Clinical predictors of leak after laparoscopic Roux-en-Y gastric bypass for morbid obesity.

BACKGROUND: Gastrointestinal leak is a complication of laparoscopic Roux-en-Y gastric bypass (LRYGB). Contrast studies may underdiagnose leaks, forcing surgeons to rely solely on clinical data. This study was designed to evaluate various clinical signs for detecting leakage after LRYGB. METHODS: We retrospectively reviewed 210 consecutive patients who underwent LRYGB between April 1999 and September 2001. There were nine documented leaks (4.3%). Clinical signs between patients with leaks (group 1) and those without leaks (group 2) were compared using univariate and multivariate logistic regression analysis. RESULTS: Evidence of respiratory distress and a heart rate exceeding 120 beats per min were the two most sensitive indicators of gastrointestinal leak. Routine upper gastrointestinal contrast imaging detected only two of nine leaks (22%). CONCLUSION: Leak after LRYGB may be difficult to detect. Evidence of respiratory distress and tachycardia exceeding 120 beats per min may be the most useful clinical indicators of leak after laparoscopic Roux-en-Y gastric bypass.

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.

Laparoscopic management of large paraesophageal hiatal hernia.

BACKGROUND: Large paraesophageal hernias (POHs) predominantly occur in the elderly population. Early repair is recommended to avoid the risks associated with gastric volvulus. METHODS: Data were collected prospectively during an 8-year period. Laparoscopic repair of POHs initially included circumcision of the sac and mesh hiatal repair. Sac excision and suture hiatal repair were later adopted. A fundoplication was also included, initially as a selective procedure. RESULTS: Fifty-three patients with large POHs were treated by one surgeon. All had attempted laparoscopic repair, with four conversions to an open procedure. Symptomatic hernia recurrence occurred in five patients (9%). The 21 patients who had sac excision, hiatal repair, and fundoplication have remained free of symptomatic recurrence. The postoperative morbidity rate was 13%, with one death. CONCLUSIONS: Laparoscopic repair of large POHs remains feasible. We advocate complete sac excision, hiatal repair, fundoplication, and gastropexy to prevent early recurrence.

Hand-assisted laparoscopic resection of serous cystadenoma of the pancreas.

It is difficult to exclude the possibility of malignancy of pancreatic cystic tumors because a biopsy of the pancreas is hard to obtain. The indication of open surgery for those cystic tumors without evidence of malignancy is controversial. Therefore, laparoscopic or laparoscopically assisted procedure would be an adequate choice of treatment for cystic tumors of the pancreas. Hand-assisted laparoscopic distal pancreatectomy with preservation of the spleen and the splenic artery and vein was performed for two cases of pancreatic cystic tumors. Three ports and one hand port were used. After careful dissection and accurate hemostasis between the pancreas and splenic vessels, laparoscopic distal pancreatectomy was carried out using an endoscopic linear stapler. There were no perioperative complications. The pathological diagnoses were oligocystic serous cystadenoma and solitary cystic serous cystadenoma, respectively. Hand-assisted, spleen-preserving laparoscopic distal pancreatectomy with preservation of the splenic artery and vein is a feasible procedure for the treatment of benign or borderline-malignant cystic lesions of the distal pancreas.

Hand dominance and performance in a laparoscopic skills curriculum.

BACKGROUND: This study evaluated the influence of hand dominance on skill acquisition during a basic laparoscopic skills curriculum. METHODS: A total of 27 surgical residents (5 postgraduate year 3 [PGY-3] and 22 PGY-2 residents) participated in a 4-week laparoscopic skills curriculum. The residents were pre- and posttested on six laparoscopic tasks during weeks 1 and 4. During weeks 2 and 3, the residents attended a proctored practice session. The results were compared using analysis of variance (ANOVA), (with significance determined by a p value less than 0.05. RESULTS: The posttest scores were significantly higher than the pretest scores. On the pretest, lefthand-dominant (LHD) surgeons (n = 4) performed significantly better than righthand-dominant (RHD) surgeons (n = 23). In the analysis of individual task pretest scores, LHD surgeons performed significantly better on pattern cutting and vessel loop application. Posttest analysis of overall performance did not show significant differences between the RHD and LHD surgeons. CONCLUSIONS: Participation in a laparoscopic skills curriculum improved overall performance. The LHD surgeons demonstrated better initial performance, but posttest comparison showed no difference between the two groups.

Totally laparoscopic transhiatal esophago-gastrectomy without thoracic or cervical access. The least invasive surgery for adenocarcinoma of the cardia?

BACKGROUND: The recent progress of minimally invasive surgery has allowed esophagectomy to be performed by both combined laparoscopic/thoracoscopic and totally laparoscopic transhiatal approaches. All these techniques imply a thoracic and/or cervical access for the creation of the esophagogastric anastomosis. METHODS: Five surgical ports are introduced in the abdomen. The stomach is mobilized, divided, and tubulized, preserving the right arteries. The lymphadenectomy of the celiac trunk and the hepatic pedicle is achieved. The dissection and resection of distal esophagus and a two-fields mediastinal lymphadenectomy are performed by means of harmonic scalpel. The realization of the intrathoracic esophago-gastrostomy is accomplished by means of a circular stapler. RESULTS: Three patients underwent the procedure. Mean operating time and blood loss were 347 min and 360 cc. There were no intraoperative or postoperative complications. Mean postoperative stay was 9 days. CONCLUSION: In selected cases, it is possible to perform a distal esophagectomy entirely by laparoscopy, without the need for any thoracic or cervical access.

A nickel-titanium memory-shape device for colonic anastomosis in laparoscopic surgery.

BACKGROUND: Minimally invasive surgery is used increasingly for colonic resection. With this procedure, the involved colon is dissected laparoscopically and exteriorized through a small incision, and the segment containing the tumor is resected. The anastomosis is performed extraperitoneally either by hand suture or with a stapler. This study was designed to evaluate the feasibility of using a memory-shape compression anastomosis clip (CAC) to perform laparoscopically assisted colonic anastomosis. The study was prompted by the authors' successful experience with the CAC in an animal model and in 10 patients with diverse colonic cancers. METHODS: The sample consisted of 10 patients who underwent laparoscopic colonic surgery at the authors' center. The anastomosis was performed with the CAC for five patients and with a stapler for five patients. To perform anastomosis with the CAC, the two edges of the resected colon are aligned. Two 5-mm incisions are made near the edges, through which the CAC, after cooling in ice water, is introduced in an open position using a special applier. In response to body temperature, the clip resumes its original (closed) position, thereby clamping the two bowel loops together. At the same time, the small scalpel incorporated in the applier makes a small incision through the clamped walls for the passage of gas and feces, and the clip is released into the intestine. The two 5-mm incisions are sutured. The clip is expelled with the stool within 5 to 7 days, creating a perfect uniform anastomosis. RESULTS: Neither group had complications, except one patient from the control group who experienced a small bowel obstruction attributable to a wound suture problem, which required laparotomy. His recovery was uneventful. CONCLUSIONS: The use of the CAC for colonic laparoscopic surgery is simple and very efficient, shortening operation time. It creates a uniform anastomosis, approximating the no-touch concept in surgery, and may prevent infection. It also is lower in cost than the stapler.

Results of thoracoscopic pleural abrasion for primary spontaneous pneumothorax.

BACKGROUND: Several video-assisted techniques have been used to treat primary spontaneous pneumothorax (PSP). The aim of this study was to evaluate the results of thoracoscopic pleural abrasion for PSP. METHODS: From 1991 to 2003, 185 consecutive patients, 143 male and 42 female, aged 15 to 60 years (average 31.6) underwent thoracoscopic pleural abrasion for PSP. The indications for surgery were as follows: a first episode with persistent air leak in 33 patients (17.9%), a recurrent ipsilateral pneumothorax in 122 patients (65.9%), a previous contralateral pneumothorax in 23 patients (12.4%), and recurrence after surgical treatment in seven patients (3.8%). Bullae were resected in 163 patients (88.1%). Mechanical pleural abrasion was performed in all cases. RESULTS: There were no deaths. Intraoperative hemorrhage occurred in three patients. It was controlled via thoracotomy in one patient and via thoracoscopy in two patients. The postoperative complication rate was 8.1% (15/185). Complications included prolonged air leak in eight patients (4.3%), pleural effusion in two (1.1%), extrapleural hematoma in one (0.5%), chest wall infection in one (0.5%), atelectasis in one (0.5%), and hemorrhage in two (1.1%). Postoperative hospital stay ranged between 2 and 17 days (mean, 5). Mean duration of drainage was 3.8 days (range; 1-16). Postoperatively, 111 patients were contacted, with a mean follow-up of 36.5 months. Four of them had a recurrence (3.6%) that did not require reoperation. CONCLUSION: Thoracoscopic pleural abrasion associated with bullae resection is a safe and efficient treatment for PSP. Results remain stable in the long term.

Five-year outcome of laparoscopic and Lichtenstein hernioplasties.

BACKGROUND: Laparoscopic hernia repair has been proved superior to open repairs in terms of short-term results, but long-term results of laparoscopic and open mesh repairs have been lacking until recently. METHODS: A total of 123 patients were randomly allocated to two treatment groups comparing laparoscopic and Lichtenstein hernioplasties in three separate trials. The first and second trials compared small and large mesh used in transabdominal preperitoneal repairs, and the third study compared totally extraperitoneal hernioplasty with the Lichtenstein operation. A 5-year follow-up visit was scheduled to assess recurrencies, symptoms, and patient satisfaction. RESULTS: For the follow up evaluation, 121 (98.4%) of the patients were reached. There were five hernia recurrences in the laparoscopic group (small mesh) and two in the Lichtenstein group (difference, 5%; 95% confidence interval, -4-13%; p = 0.3). One patient who underwent the transabdominal preperitoneal polypropylene procedure underwent reoperation 3 years later because of dense small bowel adhesions at the inguinal surgical site. Chronic groin pain was more common after open operation (0 vs 4) patients (difference 7%; confidence interval, -0.4-16%; p = 0.04). Ten patients (16%) in the laparoscopic group and 12 (20%) in the open group reported discomfort or pain at the surgical site. CONCLUSIONS: Both laparoscopic and Lichtenstein hernioplasties have a low risk for hernia recurrence if proper mesh size is used. The patients who undergo hernioplasty with open mesh hernioplasty seem to experience chronic symptoms and pain more often than those managed with the laparoscopic procedure.

Laparoscopic rectopexy for full-thickness rectal prolapse: a single-institution retrospective study evaluating surgical outcome.

BACKGROUND: The laparoscopic approach promises to become the gold standard for the transabdominal management of full-thickness rectal prolapse. The aim of this study was to review our experience and to highlight the functional results achieved with this new technique. METHODS: Forty-eight patients with full-thickness external prolapse underwent laparoscopic repair between February 1997 and February 2003. All patients underwent preoperative evaluation of their rectal function. Patients with isolated rectal ulcer without prolapse or with internal prolapse and patients deemed by the anesthesiologist to be unfit for general anesthesia were excluded from the study. The laparoscopic technique was either a mesh rectopexy without resection (n = 35) or a suture rectopexy with sigmoid resection (n = 13). Patients with intractable constipation preceding the development of the rectal prolapse were advised to have a resection-rectopexy. In the postoperative follow-up, attention was paid to mortality, morbidity, recurrent prolapse, incontinence, and constipation. Follow-up was done by clinical review and postal questionnaire. RESULTS: There were no deaths and no septic or anastomotic complications. The postoperative morbidity rate was 5%. Oral intake was started on postoperative day 1. Discharge from the hospital was on postoperative day 4 in patients without sigmoid resection and on postoperative day 7 in patients with sigmoid resection. Two patients (4%) developed recurrent total prolapse during a median follow-up period of 36 +/- 15 months (range, 7-77). The functional results were good or excellent in 72% of the cases, without digitations or dyschesia. Continence was improved in 31% of the patients and remains unchanged in 64% of them. In 11 patients (23%), constipation was worsened by the procedure. CONCLUSION: Laparoscopic rectopexy with or without resection is both safe and effective. Advantages include low-morbidity, improved cosmesis, the rapid return of intestinal function, early discharge from hospital, and a low recurrence rate. The fecal continence score is improved; however, constipation is frequently worsened.

Laparoscopically assisted reversal of Hartmann's procedure.

BACKGROUND: Restoration of bowel continuity after Hartmann's procedure is a major surgical procedure associated with substantial morbidity and occasional mortality. The authors review their experience with laparoscopically assisted reversal of Hartmann's procedure (LARH) to assess difficulties and potential advantages associated with this procedure. METHODS: A retrospective chart review of a prospectively entered database was performed to identify patients who underwent LARH over a period of 7 years. Data regarding demographic and clinical characteristics, surgical details, and postoperative course were reviewed. Specifically, age, gender, diagnosis at initial operation, American Society of Anesthesiology (ASA) score, comorbidities, operative time, conversion, surgical team, complications, postoperative bowel movements, and hospital stay were assessed. All surgeries were performed by six experienced laparoscopic surgeons. RESULTS: A total of 27 patients, 17 men and 10 women, with mean ages of 58.1 and 62.9 years, respectively, underwent LARH. The procedure was laparoscopically completed for 23 patients. Conversion to laparotomy was required for four patients (14.8%) because of dense adhesions after the initial Hartmann's procedure in three patients and rectal perforation in one patient. The median operative time was 226 min, and the median hospital stay was 6 days. The overall morbidity rate was 33% (9 patients), attributable to colostomy site infection in 5 of the 9 patients. One patient required reoperation because of intraabdominal bleeding. No anastomotic leaks or intraabdominal abscesses were recorded. There was no operative mortality. CONCLUSIONS: Laparoscopically assisted reversal of Hartmann's procedure is technically challenging and time consuming. However, in the hands of experienced laparoscopic surgeons, it is safe and associated with a reasonably low conversion rate. Furthermore, the relatively low morbidity rate, short hospital stay, and earlier return of bowel function may be beneficial to patients.

Laparoscopic bariatric surgery.

Laparoscopy has meant profound changes for the field of bariatric surgery. Bariatric operations, which are technically difficult because of the patient population, were not performed laparoscopically until the last 5 years of the 20th century. The years 1998 to 2003, herein defined as the Bariatric Revolution, saw profound changes in the way bariartric surgery was practiced. Major changes in patient education, public awareness, patient enthusiasm, popularity of the surgery, and academic acceptance of bariatric surgery occurred during this time. This led to such a massive increase in procedures performed that there was a reactionary movement by insurers to deny coverage for these procedures. Limitation of access to care and other important socioeconomic issues are now being debated and confronted in the bariatric arena. Recommendations for the field are suggested. The outcomes of these controversies will potentially have a profound impact on all of surgery.

New applications for endoscopy: the emerging field of endoluminal and transgastric bariatric surgery.

Endoluminal and transgastric procedures are evolving concepts that combine the skills and techniques of flexible endoscopy with minimally invasive surgery. Precisely how this technology and skill set will be applied in the field of general surgery is not yet known, but the treatment of obesity with an endoluminal or transgastric procedure holds great promise. As the demand for bariatric surgery increases, efforts will be directed toward developing less morbid and less costly treatment options that can provide substantial weight loss and resolution of comorbid conditions. Natural orifice bariatric procedures may include short-term weight loss in preparation for a definitive laparoscopic procedure, revisional procedures to reduce stoma or pouch size or repair fistulas, or primary therapy that provides durable weight loss. The latter application will undoubtedly appeal to patients and referring physicians if it can be performed as an outpatient procedure with significantly less morbidity than a laparoscopic procedure. Early preclinical and clinical work has been published in this area, but many technical obstacles must be overcome before a primary endoluminal or transgastric bariatric procedure can be offered. This article reviews the endoluminal and transgastric technology currently available, the endoluminal procedures currently performed, and the future of these technologies with respect to bariatric surgery.

Laparoscopic treatment of ventral hernia. A bilayer repair.

Laparoscopic repair of abdominal wall hernias has been introduced recently to treat both spontaneous and incisional hernias with reported good results. In the Mafraq and Al Jaziera Hospitals in the United Arab Emirates, 18 patients have been treated using the laparoscopic technique. These cases included 11 incisional hernias, 5 spontaneous paraumbilical hernias, and 2 combined incisional and paraumbilical hernias. A bilayer repair was performed in all cases using a layer of polyester mesh to bridge the defect and a sheet of Gore-Tex (W. L. Gore & Associates, Flagstaff, AZ, USA) to prevent adhesions between first layer and the bowel. Seroma at the hernia site was the most frequent postoperative complication. Hospital stay ranged from 2 to 7 days (mean, 3.2 days). Recurrent hernia developed in one patient after a mean follow up of 22.3 months. This technique is in its evolution. Long follow-up evaluation is required before the effect on recurrence is known, and further development regarding the composition of prosthetic biomaterials and the methods of its fixation is expected.

Hand-assisted laparoscopic colorectal surgery.

Hand-assisted laparoscopic surgery is a newly developed technique. It involves the intraabdominal placement of a hand or forearm through a mini-laparotomy incision while pneumoperitoneum is maintained. In this way, the hand can be used as in an open procedure to palpate organs or tumors, reflect organs atraumatically, retract structures, identify vessels, dissect bluntly along a tissue plain, and provide finger pressure to bleeding points while proximal control is achieved. Additionally, this approach is more economical than a totally laparoscopic approach, reducing both the number of laparoscopic ports and number of instruments required. Some advocates of the technique claim that it is also easier to learn and perform than totally laparoscopic approaches and that it may increase patient safety.

Lobectomy with extended lymph node dissection by video-assisted thoracic surgery for lung cancer.

BACKGROUND: Between September 1992 and September 1996, we performed 88 VATS (video-assisted thoracic surgery) lobectomies and two VATS pneumonectomies. METHODS: The indications for surgery were 68 cases of lung cancer, nine cases of bronchiectasis, six cases of tuberculosis, and seven cases of benign lesions. Of the 68 cases of lung cancer, 36 were treated by VATS lobectomy with extended lymph node dissection for clinical stage I lung cancer, making full use of recently developed devices for thoracoscopic surgery, such as roticulating endoscissors, miniretractors, endoclips, and harmonic scalpels. RESULTS: Twenty-four lymph nodes were resected on average (range, 10 to 51) by VATS. This number was comparable to lymph nodes resected in open thoracotomy during the same period. Among the 36 patients who underwent extended lymph node dissection, 20 showed no lymph node metastasis postoperatively (stage I), while 16 had N1 or N2 cancer. All patients with stage I cancer have survived 4 to 36 months (median: 17 months) with no signs of recurrence. CONCLUSIONS: This survival of stage I lung cancer after VATS is comparable to that of open thoracotomy. We thus believe that VATS lobectomy with extended lymph node dissection can be an alternative to standard posterolateral thoracotomy for stage I lung cancer.
