Prospective comparison of laparoscopic left hemicolectomy for colon cancer with laparoscopic left hemicolectomy for benign colorectal disease.

BACKGROUND: Short-term outcome and anorectal function results after laparoscopic hemicolectomy for colon cancer were compared with results after laparoscopic hemicolectomy for benign diseases. METHODS: A total of 108 patients who underwent laparoscopic left colectomy (60 for colon cancer, 48 for diverticulitis or polyposis) were enrolled in the study. Left hemicolectomy in patients affected by cancer was performed by high ligation of the inferior mesenteric artery. A questionnaire concerning anorectal function was mailed to patients 6 months after surgery. RESULTS: Complications were more frequent in the cancer group than in the benign disease group: overall morbidity rate (29.6% versus 8.7%; P = 0.009), diarrhea during the first 6 postoperative months (58.7% versus 34.1%; P = 0.022), and anorectal function problems (fecal incontinence and/or the inability to discriminate between gas and stool, and/or urgency, and/or tenesmus) (65.2% versus 31.7%; P = 0.002). DISCUSSION: The level of ligation of the lower mesenteric artery and damage at the lower mesenteric ganglion could explain the poorer anorectal function outcome in the colon cancer group.

Laparoscopic management of complications following laparoscopic Roux-en-Y gastric bypass for morbid obesity.

BACKGROUND: We reviewed our experience with complications following laparoscopic Roux-en-Y gastric bypass (LRYGB) that were managed laparoscopically. METHODS: A total of 246 consecutive morbidly obese patients (mean body mass index, 50.9 kg/m2) underwent LRYGB by three surgeons at two institutions. All patients met National Institutes of Health criteria for surgical treatment of morbid obesity. Patients were followed prospectively. RESULTS: A total of 62 patients (25.2%) developed 64 complications, 34 of which (13.8%) required a surgical intervention. Twenty-seven of the 34 procedures were performed laparoscopically. Gastrojejunostomy stricture was the most common complication (8.9%), followed by intestinal obstruction (7.3%) and gastrointestinal bleeding (4%). The intestinal obstruction was secondary to adhesions (n = 6), internal hernia at the level of the transverse mesocolon (n = 3), jejunojejunostomy stricture (n = 3), and cicatrix around the Roux limb at the level of the transverse mesocolon (n = 3). Other complications included gastrojejunostomy leak (1.6%), symptomatic gallstone disease (2.8%), and gastric remnant perforation (0.8%). One patient underwent a negative laparoscopy to rule out anastomotic leak. There were 3 deaths in this series of patients, 2 attributable to anastomotic leak. CONCLUSIONS: A variety of complications can present after LRYGB. Laparoscopy is an excellent technique to treat these complications.

Minimal invasive approach of gastric and esophageal mobilization in total pharyngolaryngoesophagectomy: total laparoscopic and hand-assisted laparoscopic technique.

BACKGROUND: To evaluate early results in total pharyngolaryngoesophagectomy (PLE) by minimally invasive approaches for patients suffered from pharyngoesophageal tumor. METHODS: Between April 1998 and September 2001, 12 consecutive patients underwent either total laparoscopic (n = 9) or hand-assisted laparoscopic (n = 3) gastric mobilization plus transhiatal esophageal resection in total PLE. The operative data and postoperative outcomes were evaluated. RESULTS: Total PLE by minimally invasive approach was successfully performed in 11 patients, and 1 patient required conversion due to uncontrolled bleeding. The median total operative time was 8.5 h (range, 5-11 h) and the abdominal laparoscopic stage usually took less than 4 h. The median time for extubation was 2 days (range, 1-4 days) and the median ICU stay was 2 days (range, 1-20 days). There was no 30-day mortality, and major complications occurred in 5 patients (42%). CONCLUSION: Minimally invasive PLE is a feasible and safe alternative to conventional open surgery for patients with pharyngoesophageal carcinoma.

A comparison of the complication rates between laparoscopic colectomy and laparoscopic low anterior resection.

BACKGROUND: This study compared the short-term outcomes, including the complication rate and minimum surgical invasiveness, between patients with colon and rectal carcinomas, who underwent laparoscopic surgery. METHODS: A review evaluated 151 patients who underwent laparoscopic colectomy (Lap-colectomy; n = 120) and laparoscopic low anterior resection (Lap-LAR; n = 31) between July 2001 and December 2003. The short-term outcomes were compared between the two groups. RESULTS: The mean operative time and blood loss were significantly greater in the Lap-LAR group. However, the complication rates and postoperative course between the two approaches were similar, and no anastomotic leakage was observed. There was no significant difference in the serum C-reactive protein level and white blood cell count between the two groups in the early postoperative period. CONCLUSIONS: Lap-LAR for rectal carcinoma can be performed safely without increased morbidity or mortality, and its short-term benefits are comparable with those conferred by Lap-colectomy.

Outcomes of laparoscopic Toupet compared to laparoscopic Nissen fundoplication.

BACKGROUND: Recent reports suggest that partial fundoplications such as the laparoscopic Toupet (LT) ultimately suffer from a higher recurrence rate compared to complete wraps such as the laparoscopic Nissen fundoplication (LNF). This article summarizes our experience with LT and LNF. METHODS: Over a 45-month period (February 1995 to November 1998), 206 patients underwent laparoscopic antireflux operations. The LNF group included 163 patients and the LT group included 43 patients. Global quality of life was measured using the Medical outcomes short form 36 (SF36). RESULTS: There were no differences in disease severity, except that the LT group had a higher incidence of esophageal dysmotility (37.2% 8.6%, p < 0.05). Early outcomes were similar, with no perioperative deaths and morbidity occurring in 15 (9.2%) LNF and 5 (11.6%) LT patients (p = not significant). Long-term follow-up was available in 142 patients at a mean of 19.7 months. A greater number of LT patients required proton pump inhibitors (38 vs 20%) and were dissatisfied (21 vs 7%) with their surgery (p < 0.05). SF36 physical function scores were better in the LNF group (85 vs 74; p < 0.05). Significantly more (p < 0.05) of the LT patients complained of dysphagia (34.5 vs 15%) on follow-up. There were no differences in the incidence of symptoms related to the gas-bloat syndrome. The observed differences between the LT and LNF groups did not appear to be related to differences in esophageal motility. CONCLUSIONS: Short-term results were similar for LT and LNF, but with longer follow-up, better results were seen with LNF. Even in the setting of moderate decreases of esophageal motility, complete fundoplication yields superior results.

Comparison of laparoscopic performance in vivo with performance measured in a laparoscopic simulator.

BACKGROUND: Laparoscopic skill was measured objectively through a series of seven tasks in an inanimate laparoscopic simulator. Seven analogous skills were tested in an in vivo porcine model. These skills included transferring, cutting, clipping, placement of a ligating loop, mesh placement, and suturing with an intracorporeal and extracorporeal knot. Scoring of each task rewarded precision and speed. METHODS: Twelve PGY3 residents were given a baseline evaluation in the simulator and in the animal model. They were then randomized to either five practice sessions in the simulator (group A) or no practice (group B). Each group was retested in the simulator and in the animal (final test). Scores in vivo were compared by t-test for baseline versus final evaluation for each group. Linear regression analysis was used to correlate in vivo and in vitro scores for each task and for the total score (sum of all scores). RESULTS: Group A showed significant improvement in performance in vivo for cutting, clipping, mesh placement, and suturing with an intracorporeal and extracorporeal knot, as well as in the total score (p < 0.05). Group B showed significant improvement in suturing with an intracorporeal and extracorporeal knot, and in the total score. The magnitude of improvement from baseline to final evaluation was significantly greater for group A (p < 0.05). There was significant correlation between in vitro and in vivo total scores and the score for each task (p < 0.05) except for placement of the ligating loop and mesh. CONCLUSIONS: Performance in an in vitro laparoscopic simulator correlated significantly with performance in an in vivo animal model. Practice in the simulator resulted in improved performance in vivo.

Laparoscopic reoperative surgery after laparoscopic fundoplication: an initial experience.

BACKGROUND: Primary fundoplication results are good to excellent. We explored failure patterns and results of redo fundoplication surgery. STUDY DESIGN: Between January 1999 and July 2002, 10 redo laparoscopic fundoplications were attempted, 1 for the third time. Indications were large symptomatic hiatal hernia-2, hiatal hernia with reflux-2, hiatal hernia with reflux and dysphagia-1, hiatal hernia with dysphagia-2, bloating with dysphagia-1, dysphagia-1, and dysphagia for the third attempt. RESULTS: Two conversions (20%) were caused by dense adhesions at the crura and mediastinum. There were 8 recurrent hiatal hernia repairs. Fundoplication was left in place in 2 patients. Fundoplication was redone in 4 (2 were slipped), converted to Toupet in 2, or taken down in 1 (with esophageal myotomy). Pyloroplasty was performed in 2 patients and cruroplasty in 1. Laparoscopy operating room time was 140 (64 to 210) minutes and converted 210 and 295 minutes. Intraoperative complications occurred in 30% of patients (gastric perforation 1, bilateral chest tubes 2). Length of hospital stay was 3 (1 to 8) days for laparoscopic, 3 and 5 for converted. One patient was reoperated on acutely for a hiatal reherniation. Follow-up was 16 (1 to 40) months: 3 were symptom free, 2 had mild reflux symptoms, and were on prn H2 blockers, 1 mild bloating, 2 mild dysphasia, 2 moderate dysphagia, 1 had been dilated, and the other failed dilation and was redone. CONCLUSIONS: Hiatal hernia was the most common cause of symptoms leading to redo surgery. Laparoscopic redo surgery is effective for dysphagia and recurrent heartburn. Results are not as good as for first-time fundoplication and morbidity is higher.

Laparoscopic creation of a neovagina with the laparoscopic Vecchietti operation: comparison of two instrument sets.

OBJECTIVE: To compare safety and effectiveness of two different instrument sets for the laparoscopic Vecchietti operation for the creation of a neovagina. DESIGN: Descriptive study. SETTING: Tertiary referral center. PATIENT(S): Twenty-six women with Rokitansky syndrome. Twelve consecutive patients had surgery with the kit recently developed by Storz (group 1) and 14 consecutive patients had surgery with the original kit of Vecchietti (group 2). INTERVENTION(S): Laparoscopic Vecchietti operation and clinical and instrumental follow-up for all patients. MAIN OUTCOME MEASURE(S): All the parameters reflecting safety, effectiveness, and compliance that were systematically measured for all patients. RESULT(S): Patients in group 1 had a wider vagina at device removal and experienced less vaginal bleeding than patients in group 2, and the removal of the device was simpler. Patients in group 1 had a shorter vagina at device removal and retained the device and the Foley catheter for a longer period than patients in group 2. Diameter and length of neovagina at 1-month follow-up were comparable in the two groups. CONCLUSION(S): The availability of this new instrument set represents a small but significant improvement in the creation of a neovagina by the laparoscopic Vecchietti operation in women with Rokitansky syndrome.

Simultaneous laparoscopic prosthetic mesh inguinal herniorrhaphy during transperitoneal laparoscopic radical prostatectomy.

Concurrent repair of inguinal hernias during open radical retropubic prostatectomy is well described and commonly practiced. With the advent of the laparoscopic approach to radical prostatectomy, the possibility of concurrent laparoscopic hernia repair merits investigation. We present a case of simultaneous prosthetic mesh onlay hernia repair for bilateral inguinal hernias during laparoscopic transperitoneal radical prostatectomy.

Comparison of laparoscopic partial nephrectomy and laparoscopic cryoablation for renal hilar tumors.

OBJECTIVES: To compare laparoscopic partial nephrectomy (LPN) and laparoscopic cryoablation (LC) for the management of small renal tumors located near the renal hilum. METHODS: A retrospective chart review was performed on all patients who underwent LPN and LC. A total of 23 patients (12 LPN and 11 LC) had tumors located within 5 mm of the renal hilar vasculature. Patient data were retrospectively analyzed for specific parameters, including operative time, efficacy, morbidity, and postoperative course. RESULTS: All 23 cases were successfully completed laparoscopically. The mean operative time for LPN and LC was 2.8 hours and 2.3 hours, respectively (P = 0.03). The mean estimated blood loss was 197 mL for LPN and 70 mL for LC (P < 0.01). The analgesic requirement for those undergoing LPN and LC was 29 mg morphine equivalent and 23 mg morphine equivalent, respectively (P = 0.41). The hospital stay for patients in the LPN and LC groups was 3.9 days and 3.2 days respectively (P = 0.55). No intraoperative complications occurred in either group. Six patients experienced nine complications in the LPN group. The complications included hemorrhage in 1, fever in 1, ileus in 1, urinary tract infection in 1, urine leak in 4, and transient postoperative neuropathy in 1. The LC group had no postoperative complications. In the LC cohort, no disease recurrence developed during the 11.3 months of follow-up. No positive margins were found in the LPN cohort, and with a mean follow-up of 12 months, none have developed recurrence. CONCLUSIONS: LPN for hilar tumors is a reasonable surgical option but carries an increased risk of urine leak. LC for hilar tumors has a shorter operative time and results in significantly fewer postoperative complications. Long-term follow-up data for both techniques remain unavailable.

[Immediate postoperative complications after a laparoscopic partial posterior fundoplication. Early laparoscopic reoperation].

AIM OF THE STUDY: The immediate postoperative course of laparoscopic partial posterior fundoplication can be complicated by severe dysphagia or paraesophageal hernia. The aim of this study was to describe the technical causes of these complications. PATIENTS AND METHOD: Four patients, operated for gastroesophageal reflux disease by laparoscopic partial posterior fundoplication, developed severe dysphagia (n = 2) or paraesophageal hernia (n = 2) during the immediate postoperative period. A barium swallow examination visualized the complication in both cases of dysphagia and in 1 case of paraesophageal hernia. The correct diagnosis was established by CT scan in the other case of paraesophageal hernia. Reoperations were performed by laparoscopy, 3 days (n = 2) or 6 days (n = 2) postoperatively. RESULTS: Dysphagia was due to compression of the esophagus against the hiatus by the fundoplication. A new and looser fundoplication was easily performed. Dysphagia was no longer present postoperatively. The two patients were symptom-free after 6 and 12 months of follow-up, respectively. In the cases of paraesophageal hernia, the bottoms of the crura were torn. In the patient reoperated 3 days postoperatively, the procedure was easily performed, the postoperative course was uneventful and the patient was symptom-free after a follow-up of 20 months. In the patient reoperated 6 days postoperatively, the upper part of the stomach had moved into the left pleural cavity, the procedure was difficult due to inflammation and thickening of the gastric wall, and the postoperative course was uneventful, but reflux recurred 18 months later. CONCLUSION: When severe dysphagia or paraesophageal hernia occurs during the immediate postoperative course of laparoscopic partial posterior fundoplication, reoperation, possibly by laparoscopy, identifies and cures the technical defects. Based on our experience, we suggest that surgical cure of paraesophageal hernia is easier when performed during the immediate postoperative period.

[Laparoscopic repair of secondary lumbar hernias: open vs. laparoscopic surgery. A prospective, nonrandomized study].

INTRODUCTION: Lumbar hernia is an uncommon defect of the posterior abdominal wall and its surgical treatment remains controversial. The aim of the present study was to evaluate the utility of laparoscopy versus open surgery. PATIENTS AND METHOD: We performed a prospective, nonrandomized study of 16 patients with secondary lumbar hernias who underwent surgery between January 1997 and January 2003. Nine patients underwent laparoscopy and 7 underwent open surgery. The variables analyzed were clinical features, hospital data (operating time and length of hospital stay), patient comfort (analgesic consumption and return to normal daily activity) and recurrences. Hospital costs were also analyzed. RESULTS: No differences were found between the two groups in age or history, although the size of laparoscopically-repaired defects was smaller. Mean operating time, postoperative morbidity, mean length of hospital stay, analgesic consumption, and return to daily activities were significantly lower in the laparoscopic group (P<.01). No statistically significant differences in the cost of the process were found according to surgical approach but significant differences were found in final cost after including the cost of readmissions and recurrences (P<.01). CONCLUSIONS: In our series, the laparoscopic approach was more effective than traditional open surgery in the repair of secondary lumbar hernias while the cost of the two procedures was the same.

Laparoscopic loop ligatures for bladder repair during laparoscopic surgery.

In this paper, we report a case where a bladder perforation occurred during a laparoscopically assisted vaginal hysterectomy and was repaired by laparoscopic loop ligatures. This is the first case report of using the laparoscopic loop ligatures to close the bladder perforations. The loop ligature is an easy and quick procedure, which can be performed by most surgeons who take the time to learn the endoscopic suturing techniques.

Laparoscopic supracervical hysterectomy versus laparoscopic-assisted vaginal hysterectomy.

STUDY OBJECTIVE: To compare laparoscopic supracervical hysterectomy (LSH) with laparoscopic-assisted vaginal hysterectomy (LAVH) in terms of indications, pathology, length and weight of removed uteri, operative time, intraoperative blood loss, intra and postoperative complications, and later sexual function. DESIGN: Cohort retrospective analysis of consecutive cases (Canadian Task Force classification II-3). SETTINGS: Hutzel Hospital, Detroit Medical Center,Wayne State University, Detroit, Michigan; Vert-Pre Nouvelle Clinique, Geneva, Switzerland; and Benha University Hospitals, Egypt. PATIENTS: Two hundred and fifty-nine women. INTERVENTIONS: LSH and LAVH. MEASUREMENTS AND MAIN RESULTS: Patients in both groups were matched regarding age, indications, and pathology of the removed uteri. Blood loss with the LSH procedure was significantly lower than it was with the LAVH procedure (mean 125 +/- 5 vs 149 +/- 7 mL, p =.001). Patients that underwent LSH had significantly shorter operating times (mean 120 +/- 3 vs 150 +/- 5 minutes, p =.007). The length of the removed uteri was 14.2 +/- 0.5 cm (range 5.2-18) in the LSH group versus 11.8 +/- 0.4 cm (range, 5.6-14) in the LAVH group. Weight of the removed uteri was 280 +/- 6 g (range, 65-750) in the LSH group compared with 235 +/- 8 g (range, 59-560) in the LAVH group. There was no difference between the groups in hospital length of stay. The number of complications was less in the LSH group (3/123, 2.4%) compared with 5/136 (3.7%) in the LAVH group. Sexual function after surgery was better in the LSH group. CONCLUSION: After exclusion of preoperative cervical disease, LSH can be considered as a safer alternative to LAVH in patients that are candidates for laparoscopic hysterectomy.

Addition of laparoscopic uterine nerve ablation to laparoscopic bipolar coagulation of uterine vessels for women with uterine myomas and dysmenorrhea.

STUDY OBJECTIVE: To assess the effectiveness of laparoscopic uterine nerve ablation (LUNA) in women with dysmenorrhea caused by uterine myomas treated by laparoscopic bipolar coagulation of uterine vessels (LBCUV). DESIGN: Prospective, randomized, longitudinal study (Canadian Task Force classification II-1). SETTING: Private practice, university-affiliated hospital. PATIENTS: Eighty-five women with uterine leiomyomas and associated dysmenorrhea. INTERVENTION: Laparoscopic bipolar coagulation of uterine vessels with or without LUNA. MEASUREMENTS AND MAIN RESULTS: Of 85 patients who entered the study, 41 were assigned to undergo LBCUV-LUNA (group A), which was successful in 40 (97.6%). In 44 women assigned to have LBCUV only (group B), 43 (97.7%) underwent successful surgery. Eighty women completed 1-, 3-, and 6-month follow-up (38 group A, 42 group B). The groups did not differ significantly in age, history of abdominopelvic surgery, intraperitoneal adhesions, endometriosis, concomitant surgery, and operating time. Seven (18.4%) of 38 women in group A and 12 (28.6%) of 42 in group B experienced lower abdominal pain postoperatively. Acceptable pain was defined as a score of zero or 1: 31 and 30 women in groups A and B reported scores of zero; 3 and 2 reported scores of 1; 4 and 8 reported scores of 2; zero and 2 reported scores of 3; and no patients reported scores of 4. The frequency and severity of postoperative pain were less in group A than in group B (both p <0.05). The efficacy of both methods was almost equal in shrinking the uterus and dominant myoma, and in improving menorrhagia and bulk-related symptoms. Dysmenorrhea improvement was 84.2% and 61.9% in groups A and B at 3 months and 92.1% and 73.8% at 6 months, respectively. This was more significant in group A than in group B (p <0.05). CONCLUSION: Our results suggest that LUNA may decrease postoperative ischemic pain and improve dysmenorrhea associated with uterine myomas treated by LBCUV.

Single-center comparison of purely laparoscopic, hand-assisted laparoscopic, and open radical nephrectomy in patients at high anesthetic risk.

BACKGROUND AND PURPOSE: The laparoscopic approach for management of high-risk patients with renal-cell carcinoma (RCC) may reduce perioperative and postoperative morbidity. The aim of this study was to compare the outcome of purely laparoscopic radical nephrectomy (LRN), hand-assisted laparoscopic radical nephrectomy (HALRN), and open radical nephrectomy (ORN) for renal tumors in a population of patients at high risk for perioperative complications. PATIENTS AND METHODS: All patients undergoing radical nephrectomy for presumed RCC between August 1999 and August 2001 at Vanderbilt University Medical Center and having an American Society of Anesthesiologists (ASA) score of >/=3 were reviewed. Patients with known metastasis, local invasion, caval thrombi, or additional simultaneous surgical procedures were excluded from analysis. Thirteen patients underwent LRN, eight patients underwent HALRN, and 26 underwent ORN. The patient demographics were similar in the three groups. The groups were compared with regard to intraoperative and postoperative parameters. Statistical analysis was done using chi-square testing for categorical variables and analysis of variance (ANOVA) for continuous variables. Differences in outcomes were examined using ANOVA and Dunnett's T for pairwise comparisons. RESULTS: The ASA 4 patients had significantly longer hospital stays and total hospital costs than the ASA 3 patients. The mean operative time in the ASA 3 patients was similar in the three groups: 2.8 hours, 2.8 hours, and 2.5 hours for the LRN, HALRN, and ORN patients, respectively. Both the LRN patients (22.9 mg of morphine sulfate equivalent) and the HALRN patients (42.1 mg) required less pain medication than the open surgery patients (97.7 mg). When the total hospital costs were compared, LRN was less costly than HALRN ($6089 v $7678; P = 0.57) and open surgery ($6089 v $7694; P = 0.04). The complication rate in the LRN, HALRN, and ORN group was 0%, 25%, and 27%, respectively, although the differences were not statistically different (P = 0.12). CONCLUSIONS: Both LRN and HALRN can be performed safely in patients with significant comorbid conditions. Careful preoperative preparation, intraoperative monitoring, and awareness of laparoscopy-induced oliguria can preclude inadvertent overhydration, hemodilution, and congestive heart failure. Both LRN and HALRN result in less pain medication requirement and faster return to oral intake than ORN, and LRN results in fewer perioperative complications than HALRN or ORN in patients at high perioperative risk. The LRN technique has a 21% lower total cost than both HALRN and ORN.
