Colorectal carcinoma: laparoscopic versus traditional open surgery. A clinical trial.

BACKGROUND/AIMS: The purpose of this perspective study was to define the role of laparoscopic surgery in the treatment of colorectal carcinoma. METHODOLOGY: One hundred colorectal cancer patients were submitted to surgical treatment between 1993 and 1996. Fifty patients were operated on by videolaparoscopy, the other 50 were operated on according to the standard "open" technique. The two groups had similar demographic (age, gender), pathological (site, stage), and surgical (type and extent of resection) data. Early and late results, benefits and drawbacks of the minimally invasive technique are compared to those of standard open surgery. RESULTS: No intra-operative complications and no operative mortality occurred in the two groups. Early results (complications within 30 days from surgery) were: 1 pneumonia, 3 wound sepsis, and 3 fistulas (one required a reoperation) in the laparoscopic group; 2 wound sepsis and 5 fistulas (spontaneously recovered) in the open group. Late complications occurred in the laparoscopic group only: 1 bowel bridle occlusion 2 months after surgery (that required a reoperation), and 2 stenoses of the colorectal Knight-Griffen anastomosis, successfully treated by dilatation. Concerning the oncologic results, data were calculated on 40 laparoscopic and 43 open curative resections (stage I, II and III): 20% (8/40) of the laparoscopic and 23% (10/43) of the open group patients resulted in neoplastic progression. The neoplastic recurrences were single site (liver or regional) in 3 laparoscopic and in 5 open patients; multiple sites of relapse were observed in 5 laparoscopic (liver, peritoneum and 1 trocar site) and in 5 open (liver, peritoneum and 1 scar) cases. Five-year disease-free survival rates (Kaplan-Meier method) were similar in the two groups: 73.2% in the laparoscopic and 70.1% in the open. CONCLUSIONS: Laparoscopic surgery seems to be a feasible and effective treatment of colorectal cancer and, with the improvement of technology and surgeon skill, it will represent an excellent alternative to the more diffuse and consolidated open surgery technique.

[Perioperative hemorrhage associated with laparoscopic hysterectomy: retrospective study].

OBJECTIVE: To evaluate perioperative bleeding during laparoscopic hysterectomy. DESIGN: Retrospective clinical study. SETTING: Department Gynaecology and Obstetrics, Baby Friendly Hospital Kladno, Kladno, Czech Republic. METHODS: Clinical data and cases of perioperative complications and bleeding of patients after laparoscopic hysterectomy were summarized and assessed. The primary hemostatic treatment was electrosurgery. Patients were assessed to efficacy, safety, utility and applicability of vasoconstrictive and local hemostyptic agents. RESULTS: From all laparoscopic procedure were 97.6% successfully completed. There were of nine conversions (2.4%) and twenty-six (6.9%) of severe perioperative complications. The total number of perioperative bleeding was 16 (3.7%) from 376 laparoscopic hysterectomies. The mean order of blood loss was 201.6 ml (range 50-800 ml). CONCLUSION: Clinical retrospective study demonstrates that hemorrhage during and after laparoscopic hysterectomy is most perioperative complication. The laparoscopic approach to hysterectomy appears to be safe and is seen as a good, effective procedure for women with gynaecological conditions of female pelvis organs. Laparoscopic hysterectomy could potentially decrease morbidity historically associated with hysterectomy performed abdominally. Large prospective studies are needed to evaluate the surgical trauma and optimal number of perioperative complications. In conclusion, we think the oozing from the damage tissue during laparoscopic surgery can be successfully arrested and controlled using the laparoscope to apply of local hemostyptic agent.

Laparoscopic nephroureterectomy for upper tract transitional cell cancer: the Washington University experience.

PURPOSE: Laparoscopic nephroureterectomy has only recently been done to treat patients with upper tract transitional cell carcinoma. We retrospectively evaluated our experience with and long-term followup of laparoscopic nephroureterectomy, compared our results to those of contemporary series of open nephroureterectomy and reviewed the literature. MATERIALS AND METHODS: We reviewed the charts of and followed up by telephone 25 patients who underwent laparoscopic nephroureterectomy between May 1991 and June 1998, and 17 who underwent open nephroureterectomy between March 1990 and January 1997. Demographic, perioperative and followup data were compared. We performed a MEDLINE search and reviewed the literature on laparoscopic nephroureterectomy for upper tract transitional cell carcinoma. RESULTS: Laparoscopic nephroureterectomy required twice the operating time of open nephroureterectomy (7.7 versus 3.9 hours). However, patients who underwent the laparoscopic procedure had a 74% decrease in analgesia requirements (37 versus 144 mg. morphine sulfate equivalent), a 63% shorter hospital stay (3.6 versus 9.6 days) and a 72% more rapid convalescence (2.8 versus 10 weeks). Subsequent bladder transitional cell carcinoma and overall cancer specific survival were similar at a mean followup of 2 years. There was no sign of trocar site or peritoneal seeding after laparoscopic nephroureterectomy. CONCLUSIONS: Although laparoscopic nephroureterectomy is a longer operation, it has the same efficacy and is better tolerated by patients than open nephroureterectomy for upper tract transitional cell carcinoma. As operating time decreases due to surgeon experience and the recent development of hand assisted laparoscopy, laparoscopic nephroureterectomy may soon become the procedure of choice for the ablative management of upper tract transitional cell carcinoma.

Hand assisted laparoscopic radical nephrectomy for renal carcinoma using a new abdominal wall sealing device.

PURPOSE: We report our initial experience with a hand assisted laparoscopic radical nephrectomy for patients with renal carcinoma, and compare our results to those of conventional open radical nephrectomy. MATERIALS AND METHODS: The clinical data on 6 consecutive patients who underwent hand assisted laparoscopic radical nephrectomy for stage T1N0M0 renal cell carcinoma were reviewed. We performed hand assisted laparoscopic surgery using the new LAP DISC* abdominal wall sealing device. We compared the results of this procedure with those of conventional open radical nephrectomy in 12 patients with stage T1N0M0 renal cell carcinoma. RESULTS: The hand assisted laparoscopic radical nephrectomy for renal carcinoma was successfully performed without any major or minor complications in all 6 patients. Mean operation time for the laparoscopic group was significantly longer than that for the open surgery group (303 minutes versus 224 minutes, p = 0.0042). However, no significant difference was observed in mean estimated blood loss for the 2 groups (264 ml. in the laparoscopic group versus 341 ml. in the open surgery group). The frequency of parenteral analgesia postoperatively in the laparoscopic group was significantly lower than that in the open surgery group (16.7% versus 75.0%, p = 0.043). In addition, the laparoscopic group seemed to recover more rapidly than the open surgery group. The abdominal wall sealing device was easy to attach to the abdominal wall, and allowed rapid hand removal and reinsertion. CONCLUSIONS: Our preliminary results indicate that a hand assisted laparoscopic radical nephrectomy with the abdominal wall sealing device is an effective and safe surgical procedure, and is less invasive than open radical nephrectomy.

Laparoscopic radical nephroureterectomy for upper tract transitional cell carcinoma: the Cleveland Clinic experience.

PURPOSE: We report our single institutional experience with retroperitoneal laparoscopic radical nephroureterectomy in patients with upper tract transitional cell carcinoma and compare results to those achieved by the open technique. MATERIALS AND METHODS: A total of 77 patients underwent radical nephroureterectomy for pathologically confirmed upper tract transitional cell carcinoma. Of these patients 42 underwent laparoscopic nephroureterectomy from September 1997 through January 2000 and 35 underwent open surgery. All specimens were extracted intact. Of the laparoscopic group the juxtavesical ureter and bladder cuff were excised by our novel transvesical needlescopic technique in 27 and radical nephrectomy was performed retroperitoneoscopically in all 42. Data were compared retrospectively with 35 patients undergoing open radical nephroureterectomy from February 1991 through December 1999. RESULTS: Laparoscopy was superior in regard to surgical time (3.7 versus 4.7 hours, p = 0.003), blood loss (242 versus 696 cc, p <0. 0001), specimen weight (559 versus 388 gm., p = 0.04), resumption of oral intake (1.6 versus 3.2 days, p = 0.0004), narcotic analgesia requirements (26 versus 228 mg., p <0.0001), hospital stay (2.3 versus 6.6 days, p <0.0001), normal activities (4.7 versus 8.2 weeks, p = 0.002) and convalescence (8 versus 14.1 weeks, p = 0.007). Complications occurred in 5 patients (12%) in the laparoscopic group, including open conversions in 2, and in 10 (29%) in the open group (p = 0.07). Followup was shorter in the laparoscopic group (11.1 versus 34.4 months, p <0.0001). The 2 groups were similar in regard to bladder recurrence (23% versus 37%, p = 0.42), local retroperitoneal or port site recurrence (0% versus 0%) and metastatic disease (8.6% versus 13%, p = 1.00). Mortality occurred in 2 patients (6%) in the laparoscopic group and 9 (30%) in the open group. Cancer specific survival (97% versus 87%) and crude survival (97% versus 94%) were similar between both groups (p = 0.59). CONCLUSIONS: In patients with upper tract transitional cell carcinoma who are candidates for radical nephroureterectomy the retroperitoneal laparoscopic approach satisfactorily duplicates established technical principles of traditional open oncological surgery, while significantly decreasing morbidity from this major procedure. Short-term oncological and survival data of the laparoscopic technique are comparable to open surgery. Although long-term followup data are not yet available, it appears that laparoscopic radical nephroureterectomy may supplant open surgery as the standard of care in patients with muscle invasive or high grade upper tract transitional cell carcinoma.

Laparoscopic subsegmentectomy for hepatocellular carcinoma with cirrhosis: a case report.

Laparoscopic liver resection is feasible for both benign and malignant disease with present laparoscopic techniques and technology. Laparoscopic liver tumor resection is indicated instead of the conventional hepatectomy if the tumor is located in the peripheral part of the liver. Here, we reported a case of a 73-year-old woman who accepted laparoscopic subsegmentectomy for hepatocellular carcinoma of segment 6. After traditional laparoscopic trocar was settled down under the low pneumoperitoneal pressure of 8 mm Hg, laparoscopic ultrasound allowed exact localization of lesions first and then transection line was marked. Then, dissection the liver parenchyma was carried out with laparoscopic microwave coagulator and ultrasonic aspirator gradually. After operation, she resumed full diet on the second day and was discharged on the 5th post-operative day with no complications and high patient satisfaction. She had follow-up study regularly in our clinic and was disease free at nine months. With the improvement of laparoscopic techniques and the development of new and dedicated technologies, laparoscopic hepatectomy has become feasible.

Survey of urological laparoscopic practices in the state of California.

PURPOSE: In the interest of maintaining our surgical domain we performed a survey aimed at establishing laparoscopic practice patterns as they pertain to urological disease. MATERIALS AND METHODS: Surveys were mailed to 2,902 surgeons in California who were listed with the American College of Surgeons, including 2,175 general surgeons, 510 urologists and 217 obstetricians-gynecologists. RESULTS: A total of 442 complete responses (15.2%) were tallied. Of urologists and of nonurologists 54% and 11% performed no laparoscopy, while 12% and 80%, respectively, devoted at least 5% of their time to laparoscopic surgery. Urologists and nonurologists performing no laparoscopy were older than those performing a significant volume (p < 0.05). Of urologists 16% thought that they were trained adequately during residency to perform laparoscopic surgery compared with 30% of nonurologists. Of the urologists who performed hand assisted laparoscopy, 50% tended to use it as a means of gaining familiarity with these techniques. These urologists performed more laparoscopic surgery than other urologists. While 80% of laparoscopy cases were community based, academic urologists are actively interested in laparoscopic surgery. The 2 most important reasons cited for performing laparoscopy were more rapid recovery and decreased morbidity. The leading laparoscopic procedures according to incidence for urologists performing laparoscopic surgery were diagnostic procedures (12.9%), varicocelectomy (12.1%), adrenalectomy (9.7%), pelvic lymphadenectomy (8.9%), and simple nephrectomy and renal cyst decortication (8.1% each). The leading laparoscopic cases according to the number of available cases per urologist were colposuspension-bladder neck suspension (1.06), donor nephrectomy (0.77), pelvic lymphadenectomy (0.52), varicocelectomy (0.48) and orchiopexy (0.45). Urologists performed more urological laparoscopy cases than nonurologists. CONCLUSIONS: Urological laparoscopic practice in California remains in its infancy. It is imperative that exposure should be increased in residency training programs.

Laparoscopic pelvic lymphadenectomy in the surgical treatment of endometrial cancer: results of a multicenter study.

OBJECTIVE: To analyze the results and determine the contribution of laparoscopic pelvic lymphadenectomy in the surgical treatment of women with endometrial cancer and compare with the open technique. METHODS: A prospective multicenter study was carried out on 120 women who underwent laparoscopic surgery (96 women) and open procedures (24 women) for endometrial cancer between April 1996 and March 2000. RESULTS: Four patients whose laparoscopic surgery was completed by laparotomy were excluded from the study. The other 92 laparoscopic procedures were successfully completed. Laparoscopically assisted surgical staging (LASS) was performed based on the grade of the tumor and the depth of myometrial invasion. Sixty-seven of the patients underwent hysterectomy, bilateral salpingooophorectomy (BSO), and pelvic lymphadenectomy, and 25 women also had para-aortic lymph node sampling dissection. Eleven of these patients had positive pelvic or para-aortic nodes. The mean operating time for the laparoscopic procedure was significantly longer (173.8 min, P < 0.0001) than the time for the open procedure (135.0 min). The rate of complications was similar in both groups. The recovery time was significantly reduced (P < 0.0001). CONCLUSION: The laparoscopic approach to hysterectomy and lymphadenectomy for early stage endometrial carcinoma is an attractive alternative to the abdominal surgical approach. The advantages of laparoscopically assisted surgical staging are patient related. Because the abdominal incision is avoided, the recovery time is reduced. Laparoscopic pelvic lymph node dissection is a procedure that is appropriate, when applicable.

Laparoscopic nephrectomy is cost effective compared with open nephrectomy in a large county hospital.

BACKGROUND AND OBJECTIVES: To evaluate the experience with laparoscopic nephrectomy in a large county hospital and perform a cost comparison between uncomplicated open and laparoscopic nephrectomy. METHODS: Eleven consecutive patients who underwent an uncomplicated laparoscopic nephrectomy in a large county hospital were compared with 8 patients who underwent uncomplicated open nephrectomy during the same period. Patient charts and corresponding billing records were reviewed to determine overall hospitalization cost and individual cost components. RESULTS: No perioperative complications occurred in either the laparoscopic or open group, and no statistically significant differences existed between groups with regard to patient demographics or operative parameters. The overall operating room costs favored the open nephrectomy group by dollars 1070 (P=0.003). However, the overall cost of hospitalization, surgeon professional fees, duration of hospitalization, room and board costs, laboratory, and radiology costs, pharmacy costs, intravenous solution and infusion pump costs all significantly favored the laparoscopic patient group. The mean difference in overall hospital cost between laparoscopic and open nephrectomy was dollars 1211 in favor of laparoscopy (P=0.037). CONCLUSIONS: Our experience with laparoscopic nephrectomy in a large county hospital demonstrates a clear economic advantage in favor of the laparoscopic approach. Given limited funding for public hospitals and a clear patient benefit, laparoscopic nephrectomy should constitute first-line therapy when nephrectomy is indicated.

Laparoscopic appendectomy in children can be done as a fast-track or same-day surgery.

BACKGROUND: Laparoscopic surgery has reduced the length of hospital stay for common operations like cholecystectomy, gastric fundoplication, and appendectomy. We have noticed a reduction in length of hospital stay for children undergoing laparoscopic appendectomy. We, therefore, looked at our data to assess whether laparoscopic appendectomy in children could be performed as fast-track or same-day surgery (< or = 24-hour postoperative stay). METHODS: We performed a retrospective review of the records of all children who underwent laparoscopic appendectomy for suspected appendicitis during a 3-year period (7/97 to 7/00). RESULTS: Laparoscopic appendectomy was performed in 79 children (44 boys and 35 girls), between 2 to 17 years of age (mean, 11 years). In 4 (5%) children with perforated appendicitis, the laparoscopic appendectomy was converted to an open appendectomy. At operation, 51 (64.5%) had acute appendicitis, 22 (27.8%) had perforated appendicitis, 4 (5%) had ruptured ovarian cysts, and 2 (2.5%) had no pathology. The median operative time was 54 minutes. Total length of stay for all 79 patients was a median of 58 hours, and median postoperative LOS was 35 hours. Complications included wound infection (2), abdominal abscess (4), drug rash (2), and epididymo-orchitis (1). In 57 (72%) children without perforated appendicitis, the total length of hospital stay was a median of 42 hours, while median postoperative length of stay was only 28 hours. Thirty-two (56%) children went home in < or = 24 hours following laparoscopic appendectomy. No significant morbidity was noted in the nonperforated group (drug rash, 1 fever > 24 hrs, 3); and no readmissions or reoperations were necessary on follow-up. CONCLUSION: Laparoscopic appendectomy is safe and effective for treating children with appendicitis. Laparoscopic appendectomy may be safely performed as fast-track or same-day surgery, in select children without perforated appendicitis, with a postoperative stay of < or = 24 hours.

Expert videotape analysis and critiquing benefit laparoscopic skills training of urologists.

INTRODUCTION: Teaching laparoscopic skills has become the focus of the latest generation of hands-on laparoscopic courses. METHODS: Thirty-four practicing urologists, ages 31 to 61 years (mean, 46.6 years) with laparoscopic experience (range, 0 to 200, mean, 27.6 cases), 32 of whom had taken prior American Urological Association (AUA) laparoscopy courses, participated in an AUA-sponsored hands-on laparoscopic skills course over a 2-day period in August 2002 or March 2003. They all took a knowledge assessment examination and performed standardized tasks (rope passing, ring placement, and laparoscopic suturing and knot tying) at the beginning and the end of the course with a videotape analysis and critique. Prior to the repeat-skills assessment, each participant was individually critiqued and instructed based on a videotape review of their initial performance. The urologists also participated in a porcine laboratory and a pelvic trainer session totaling 6 hours between skills assessments. None of the participants had performed significant laparoscopic suturing prior to the course. RESULTS: Using Wilcoxon's signed rank test, the participants improved from a mean of 119.32 seconds to 98.36 seconds with the rope pass (P = 0.0001), and with the ring placement from a mean of 9.70/minute to 12.09/minute (P = 0.0001). All participants had significantly fewer false passes (mean, 9.35 compared with 5.21) during repeat skills assessments (P = 0.0001). Participants improved from 0.54 sutures/minute to 1.22 sutures/ minute following the video critique and practice (P = 0.0001). Degree of laparoscopic experience (number of cases), age of the urologist, and precourse knowledge (examination score) had no significant bearing on results in the initial skills assessment or in the improvement of task time (Spearman correlation coefficients). CONCLUSION: Urologists with some laparoscopic experience (mean 27.6 cases) can improve laparoscopic skills using mentored videotape analysis and experience gained from a 2-day hands-on course. Prior knowledge, degree of experience, and urologist age had no significant bearing on performance in this setting.

[Laparoscopic adrenalectomy: Akita University experience].

We performed 52 laparoscopic adrenalectomies between January 1997 and March 2003. In 51 patients, adrenal tumors were successfully removed laparoscopically. In one patient, the laparoscopic procedure was converted to open surgery because of insufflator's trouble and hemorrhage. Perioperative blood transfusion was required in two patients; one for intraoperative and another for postoperative bleeding. We compared laparoscopic adrenalectomy with conventional open surgery which had been performed in our clinic before the laparoscopic adrenalectomy era. The mean operative time of the laparoscopic adrenalectomy (187 +/- 59 min) was not significantly longer than that of the open surgery (193 +/- 49 min). The mean estimated blood loss of laparoscopic adrenalectomy (75 +/- 145 g) was significantly less than that of the open surgery (438 +/- 447 g). Time to oral intake and ambulation for laparoscopic adrenalectomy were significantly earlier than those of the open surgery. Operation time was significantly shortened as the experience of this surgery was accumulated. The results of our experience support the concept that laparoscopic adrenalectomy is safe and is a standard treatment for surgical treatment of adrenal tumors.

Endo-laparoscopic approach in the management of obstructive jaundice and malignant gastric outflow obstruction.

BACKGROUND/AIMS: Only a minority of patients with tumor at the pancreaticoduodenal junction is suitable for resection, palliation is however often required relieving the obstructive jaundice and gastric outflow obstruction (GOO). This study evaluates endo-laparoscopic approach as a palliative treatment of obstructive jaundice and malignant gastric outflow obstruction. METHODOLOGY: A retrospective review of a prospectively maintained database. During the period from 1992-2002, patients with diagnosis of unresectable tumor at the pancreaticoduodenal junction were evaluated. If the tumor was confirmed to be unresectable, patients would be offered either open double bypass or laparoscopic gastrojejunostomy (LGJ) +/- endoscopic or percutaneous transhepatic stenting for any obstructive jaundice, the choice of approach would depend on whether the endoscopic access was still maintained. RESULTS: Out of 942 patients with tumors around the pancreaticoduodenal junction during the study period from 1992-2002, there were 34 patients (13 male & 21 female) with median age 69 years (range, 48-87) selected for LGJ. Of these 34 patients, 3 of them underwent endoscopic biliary stenting whereas 16 jaundice patients were palliated by transhepatic biliary drainage. When the results were compared to the 35 open double bypass (roux-en-Y choledochojejunostomy and gastrojejunostomy) during the same study period, the median operation time was significantly shorter (80 vs. 135 minutes; P=0.0001) and median intraoperative bleeding was significantly less in the endo-laparoscopic group (0 vs. 100mL; P=0.0001). Two patients in the endo-laparoscopic group were converted to open because of tumor infiltration of the small bowel mesentery causing difficulty in construction of gastrojejunostomy. Although the overall complication rate (13 vs. 17; P=0.387) and incidence of delayed gastric emptying (7 vs. 7, P=0.952) were similar in both groups, the incidence of wound infection was remarkably less common in the endo-laparoscopic group (0 vs. 6, P=0.012). The 15 postoperative complications (13 patients) in the endo-laparoscopic group (38.2%) included prolonged gastric stasis (7), biliary sepsis (2), chest infection (2), myocardial ischemia (2), gastrointestinal bleeding (1) and extensive ischemic stroke (1). Median time to resume diet was statistically shorter in endo-laparoscopic group (5 vs. 7 days, P=0.009) however the hospital stay was similar in both groups (11.5 vs. 14 days, P=0.238). The hospital mortality rate was again comparable between the two groups (6 vs. 5, P=0.703). The short median survival in the endolaparoscopic group (3 vs. 7 months; P=0.0001) might just be a reflection of selection bias. CONCLUSIONS: With the advent of laparoscopic and endoscopic surgery, palliation of both gastric outflow obstruction and obstructive jaundice can also be accomplished using the endo-laparoscopic approach. In comparing to the open double bypass, operation time, intraoperative blood loss and incidence of wound infection are significantly less and patients can have early resumption of diet. However, the results can be improved further with a better patient selection and perioperative optimization.

Results of laparoscopic versus open abdominal and incisional hernia repair.

BACKGROUND: Incisional hernia is a frequent complication of abdominal surgery. The object of this study was to confirm the safety, efficacy, and feasibility of laparoscopic treatment of abdominal wall defects. METHODS: Fifty consecutive laparoscopic abdominal and incisional hernia repairs from September 2001 to May 2003 were compared with 50 open anterior repairs. RESULTS: The 2 groups were not different for age, body mass index, or American Society of Anaesthesiologists scores. Mean operative time was 59 minutes for the laparoscopic group, 164.5 minutes for the open group. Mean hernia diameter was 10.6 cm for the laparoscopic group, 10.5 cm for the open group. Mean length of stay was 2.1 days for the laparoscopic group, 8.1 days for the open group. Complications occurred in 16% of the laparoscopic and 50% of open group. Median follow-up was 9.0 months for the laparoscopic group, 24.5 months for the open group. Recurrence rates were 2% for laparoscopic group and 0% for the open group. CONCLUSION: Results for laparoscopic abdominal and incisional hernia repair seem to be superior to results for open repair in terms of operative time, length of stay, wound infection, major complications, and overall hospital reimbursement.

[Implementation of laparoscopic resection of the sigmoid colon, initial results and experiences].

INTRODUCTION: In recent years, the enthusiasm for laparoscopic surgery has been immense. In Denmark, laparoscopic surgery of the colon has been performed in only a few cases each year. In other countries, laparoscopic surgery foreign diseases of the colon is well established. Laparoscopic surgery for malignant diseases of the colon has been awaiting the results of studies of the oncological results. Now several randomised studies have demonstrated oncological results equal to or better than those of open surgery. The aim of this study was to show the initial experience of laparoscopic surgery of the colon in a Danish hospital surgical department. MATERIALS AND METHODS: Forty patients were included in the study. They had a planned laparoscopic resection of the sigmoid colon in the period from January 2004 to February 2005. RESULTS: Thirty-six patients had the operation done laparoscopically. Four operations were converted to open operations. Four patients had major complications. The median postoperative time in hospital was three days and five days for malignant and benign disease, respectively. In the case of malignant disease, the median number of lymph nodes in the specimen was eight, and the median distance from the resection line to the tumour was 4.5 cm. CONCLUSION: Our results seems to show that if with sufficient laparoscopic expertise, laparoscopic resection of the colon for both benign and malignant diseases can be performed with the advantage of earlier convalescence and fewer days in hospital. The histopathology findings in the case of malignant disease do not differ from those of open surgery.

Initial experience with laparoscopic adrenal surgery in children: is endoscopic surgery recommended and safe for the treatment of adrenocortical neoplasms?

Through a review of 83 cases reported in literature, including our experience of two successful right laparoscopic adrenalectomies performed in a 3-year-old girl for androgen-secreting adenoma and in a 9-year-old male for pheochromocitoma, we have anaIyzed the indications, the techniques and the results of laparoscopic or retroperitoneoscopic adrenalectomy in children. Nineteen pheochromocytomas, 18 neuroblastomas, 15 adenomas, 12 ganglioneuromas, 9 hyperplasias, 2 carcinomas, 1 teratoma and 1 adrenogenital syndrome have been treated with excellent results (follow-up 1 month to 4 years) with no evidence of recurrence. The age range is from 1 month to 16 years with an equal female/male ratio. The tumor size range from 10 mm to 80 mm with approximately a mean of 40 mm. Sixty-three laparoscopies of which 54 lateral and 9 anterior have been performed versus 14 posterior retroperitoneoscopies. Regarding right adrenalectomy, 29 were laparoscopic and only 2 retroperitoneoscopic. With regards to left adrenalectomy, 23 were laparoscopic and 9 retroperitoneoscopic. Looking at bilateral lesions, these tumors were approached laparoscopically in 6 cases alternating both sides and 1 retroperitoneoscopically (this case was already operated on the other side). The operative time ranged from 25 minutes in newborn to 320 minutes in bilateral cases with an average of 120 minutes. Conversion rate is higher in retroperitoneoscopy (30%) (4 cases out of 13), than laparoscopy (6%) (4 cases out of 63). Specifically, for right retroperitoneoscopic adrenalectomy conversion rate was 100% (2 cases out 2), for left retroperitoneoscopic adrenalectomy 22.2% (2 cases out 9), for right laparoscopic adrenalectomy 6.8% (2 cases out of 29) and for left laparoscopic adrenalectomy 8.6% (2 cases out of 23). Only in 1 case were blood transfusions requested. Hospital stays ranged from 35 hours to 17 days with an average of 4 days. In conclusion the indications of endoscopic adrenalectomy in children are not different from those of traditional surgery and the well-known advantages of laparoscopic adrenal surgery should be applied to pediatric patients. It seems that there is no age and tumor size limits for a well-trained surgical team. Lateral transperitoneal approach is the most utilized with the child positioned in 90-degree flank decubitus. Laparoscopy is undoubtly preferred for right adrenalectomy (93% of cases), while for left adrenalectomy retroperitoneoscopy has been used in 39% of the cases. Considering the conversion rate and on the basis of our experience with adults, we recommend laparoscopic adrenalectomy for both right and left adrenal lesions, but we think that the pediatric surgeon should feel free to choose the approach in which he/she is more skilled. However, the best surgical result will be achieved if the pediatric and adult surgeon collaborate with their different experiences. Lastly, we suggest the use of new technological devices such as Ultracision Harmonic Scalpel which was a critical factor in our two successful right adrenalectomies.

Laparoscopic inguinal hernia repair in children.

BACKGROUND: This study aimed to document the authors' experience with laparoscopic inguinal hernia repair in children. METHODS: Ninety-three hernia repairs were performed in 64 children. The neck was closed with a purse string suture by using 4-0 absorbable suture. RESULTS: Ninety-three indirect inguinal hernial sacs were closed in 64 children. Nine percent of children had an ectopic testis. The mean operating time for laparoscopic ring closure was 25 minutes (range, unilateral 21 to 35; bilateral, 28 to 50). The contralateral processus vaginalis was patent in 20% of children. In 24% of children, the final procedure was modified based on the findings of a dilated internal ring. A laparoscopic ilio-pubic tract repair was done in these cases. Laparoscopic mobilization, orchiopexy followed by ilio-pubic tract repair was done in 9% of children. Scrotal swelling occurred in one child. Hydrocoele occurred in one patient. Recurrence rate was 3.1%. CONCLUSION: Laparoscopic inguinal hernia repair in children can be offered, as it is safe, reproducible, and technically easy for experienced laparoscopic surgeons. Ilio-pubic tract repair may be added in cases with dilated internal ring. Recurrence following laparoscopic ring closure can be managed with laparoscopic ilio-pubic tract repair. The long-term follow-up of laparoscopic ilio-pubic tract repair is awaited.
