Outcomes after laparoscopic Roux-en-Y gastric bypass for morbid obesity.

ObjectiveTo evaluate the short-term outcomes for laparoscopic Roux-en-Y gastric bypass in 275 patients with a follow-up of 1 to 31 months. Summary Background DataThe Roux-en-Y gastric bypass is a highly successful approach to morbid obesity but results in significant perioperative complications. A laparoscopic approach has significant potential to reduce perioperative complications and recovery time. MethodsConsecutive patients (n = 275) who met NIH criteria for bariatric surgery were offered laparoscopic Roux-en-Y gastric bypass between July 1997 and March 2000. A 15-mL gastric pouch and a 75-cm Roux limb (150 cm for superobese) was created using five or six trocar incisions. ResultsThe conversion rate to open gastric bypass was 1%. The start of an oral diet began a mean of 1.58 days after surgery, with a median hospital stay of 2 days and return to work at 21 days. The incidence of early major and minor complications was 3.3% and 27%, respectively. One death occurred related to a pulmonary embolus (0.4%). The hernia rate was 0.7%, and wound infections requiring outpatient drainage only were uncommon (5%). Excess weight loss at 24 and 30 months was 83% and 77%, respectively. In patients with more than 1 year of follow-up, most of the comorbidities were improved or resolved, and 95% reported significant improvement in quality of life. ConclusionLaparoscopic Roux-en-Y gastric bypass is effective in achieving weight loss and in improving comorbidities and quality of life while reducing recovery time and perioperative complications.

The learning curve for laparoscopic Roux-en-Y gastric bypass is 100 cases

Background: The purpose of this study was to determine the effect of operative experience on perioperative outcomes for laparoscopic Roux-en-Y gastric bypass (LGB). Methods: Between July 1997 and September 2001, 750 patients underwent LGB for the treatment of morbid obesity at our center. We evaluated the perioperative outcomes of the first 150 consecutive patients to determine if a learning curve effect could be demonstrated. The patients were divided into three groups (1, 2, and 3) of 50 consecutive patients, and outcomes for each group were compared. Results: The patients in group 3 had a larger body mass index (BMI), were more likely to have had prior abdominal surgery, and were more likely to have secondary operations at the time of LGB. Operating time decreased from a mean of 311 min in group 11 to 237 min in group 3, and technical complications were reduced by 50% after an experience of 100 cases. Conclusions: Operative time and technically related complications decreased with operative experience even though heavier patients and higher-risk patients were more predominant in the latter part of our experience. LGB is a technically challenging operation with a long learning curve. To minimize morbidity related to the learning curve, strategies for developing training programs must address these challenges.n

LAPAROSCOPIC SURGERY FOR MORBID OBESITY

Minimally invasive approaches to bariatric surgery offer significant advantages over those of open surgery. The potential of laparoscopic approaches to reduce the morbidity of these operations may exceed that of laparoscopic cholecystecomy and laparoscopic Nissen fundoplication because the access incisions for open bariatric operations have relatively greater potential for harming the morbidly obese patient. Early results of laparoscopic VBG suggest a significant decrease in perioperative morbidity compared to the open approach, with similar weight-loss results. LGB may have the lowest perioperative morbidity and mortality of all current bariatric operations. However, the reoperation rate for device-related complications or failure of the patient to lose sufficient weight appears significant. Long-term esophageal motility also remains questionable for the LGB. It is hoped that the FDA trial will address many of the issues regarding LGB. Results of Lap RYGBP are accumulating and appear promising. The early experience suggests that it is technically feasible and safe in the hands of surgeons who have appropriate training. It is associated with low perioperative morbidity, short hospital stay, and rapid recovery compared to expected results of open RYGBP. Weight loss for Lap RYGBP after 5 years is excellent. It is, however, a technically formidable operation requiring long operating times and a steep learning curve. Early results indicate that technical complications may be greater than those experienced with open RYGBP because of the learning curve. Lap RYGBP is a promising bariatric procedure with potentially significant advantages over open RYGBP. Thus, for patients in the United States, Lap RYGBP may become the preferred weight-reduction procedure. The value of hand-assisted bariatric procedures and laparoscopic malabsorption procedures must await further study.

Symptomatic improvement in gastroesophageal reflux disease (GERD) following laparoscopic Roux-en-Y gastric bypass

Background: The purpose of this study was to determine the effect of laparoscopic Roux-en-Y gastric bypass (LRYGBP) on symptomatic control of gas-troesophageal reflux disease (GERD). Methods: Morbidly obese patients (n = 435) who un-derwent LRYGBP for morbid obesity were assessed for changes in GERD symptoms, quality of life, and patient satisfaction after surgery. Results: A total of 238 patients (55%) had evidence of chronic GERD, and 152 patients (64%) voluntarily participated in the study. The mean body mass index (BMI) was 48 kg/m2. The mean excess weight loss was 68.8% at 12 months. There was a significant decrease in GERD-related symptoms, including heartburn (from 87% to 22%, p < 0.001); water brash (from 18% to 7%, p<0.05); wheezing (from 40% to 5%, p<0.001) laryngitis (from 17% to 7%, p < 0.05); and aspiration (from 14% to 2%, p<0.01) following LRYGBP. Post-operatively, the use of medication decreased significantly both for proton pump inhibitors (from 44% to 9%, p < 0.001) and for the H2 blockers (from 60% to 10%, p < 0.01). SF-36 physical function scores and the mental component summary scores improved after the operation (87 vs 71; p < 0.05 and 83 vs 66; p < 0.05, respectively). Overall patient satisfaction was 97%. Conclusion: LRYGBP results in very good control of GERD in morbidly obese patients with follow-up as late as 3 years. Morbidly obese patients who require surgery for GERD may be better served by LRYGBP than fundoplication because of the additional benefit of significant weight loss.

Comparison of laparoscopic versus open repair of paraesophageal hernia

BACKGROUNDnRecent reports suggest that laparoscopic paraesophageal hernia repair (LPHR) is feasible, but no direct comparisons with the standard open paraesophageal hernia repair (OPHR) have been reported. The purpose of this study was to compare the short-term outcome of LPHR versus OPHR at a single institution.nnnMETHODSnThe operative and postoperative courses of 95 consecutive patients undergoing open or laparoscopic repair of a paraesophageal hernia (PEH) were retrospectively reviewed, and outcomes of LPHR versus OPHR were compared.nnnRESULTSnPEH was associated with advanced age and significant comorbidity. Although the operative time was increased for LPHR, there was a significant reduction in blood loss, intensive care unit stay, ileus, hospital stay, and overall morbidity associated with LPHR compared with OPHR.nnnCONCLUSIONSnPEH is associated with significant comorbidity that increases the operative risk. Short-term outcomes for LPHR are superior to OPHR, suggesting that the laparoscopic approach is the preferred approach to paraesophageal hernia repair.

Outcomes after minimally invasive esophagomyotomy.

BACKGROUNDnThoracic surgeons traditionally performed thoracotomy and myotomy for achalasia. Recently minimally invasive approaches have been reported with good success. This report summarizes our single-institution experience using video-assisted thoracoscopy (VATS) or laparoscopy (LAP) for the treatment of achalasia.nnnMETHODSnA review of 62 patients undergoing minimally invasive myotomy for achalasia was performed. There were 27 male and 35 female patients. Mean age was 53 years (range 14 to 86). Thirty-seven (59.7%) had failed prior treatments (balloon dilation, botulinim toxin injection, or prior surgery). Outcomes studied were dysphagia score (1 = none, 5 = severe), Short-Form 36 quality of life (SF36 QOL) score, and heartburn-related QOL index (HRQOL).nnnRESULTSnSurgery included myotomy and partial fundoplication (5 VATS and 57 LAP). Mortality was zero, and complications occurred in 9 (14.5%) patients. There were 6 perforations (4 repaired by LAP and 2 open). Median length of stay was 2 days, time to oral intake was 1 day. At a mean of 19 months follow-up, 92.5% of patients were satisfied with outcome. Dysphagia scores improved from 3.6 to 1.5 (p < 0.01) but 3 patients ultimately required esophagectomy for recurrent dysphagia. HRQOL scores for heartburn and SF-36 QOL scores were comparable with control populations.nnnCONCLUSIONSnMinimally invasive myotomy and partial fundoplication for achalasia improved dysphagia in 92.5% of patients with heartburn and QOL scores were comparable with normal values at 19-month follow-up. The laparoscopic approach offers excellent results and was the preferred approach by our thoracic group for treating achalasia. Thoracic residency training should strive to include laparoscopic esophageal experience.

Outcomes of laparoscopic Toupet compared to laparoscopic Nissen fundoplication.

BackgroundRecent 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.MethodsOver 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).ResultsThere 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.ConclusionsShort-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.

Quality of life after antireflux surgery compared with nonoperative management for severe gastroesophageal reflux disease

BACKGROUNDnGastroesophageal reflux disease significantly affects a patients quality of life (QOL). Laparoscopic fundoplication offers an alternative to medical therapy, but few studies have compared outcomes. Our objective was to examine QOL scores in gastroesophageal reflux disease patients treated medically and surgically.nnnSTUDY DESIGNnWe undertook a retrospective analysis of patients undergoing surgical or medical treatment for gastroesophageal reflux disease over a 1-year period (August 1997 to August 1998). Followup QOL was measured using the Short-Form 36, and heartburn severity was measured using the Health Related Quality of Life scale (a disease-specific instrument with a best score of 0 and a worst score of 45).nnnRESULTSnLaparoscopic fundoplication was undertaken in 120 patients with a median age of 47 years (range 17 to 80 years). The medical cohort included 51 patients selected from the gastroenterology clinic with a median age of 48 years (range 17 to 82 years). Duration of heartburn was not significantly different, with 40 (78.4%) of the 51 medical and 98 (81.7%) of the 120 surgical patients having had symptoms for longer than 12 months. There were no operative deaths. There were 12 complications (esophageal perforation 1, pneumothorax 2, pneumonia 1, pulmonary embolus 3, other/miscellaneous 5). Mean length of stay was 1.6 days, time to oral intake 1.2 days, and return to normal activity 4.2 weeks. Routine followup was available in 118 surgical and 47 medical patients. The medical cohort had increased (p < 0.05) symptoms of heartburn (43% versus 19%), waterbrash (26% versus 8%), and regurgitation (30% versus 8%) and greater requirement for proton pump inhibitors (74% versus 19%) and propulsid (19% versus 3%) over the surgical group. Detailed outcomes were available in 101 surgical and 37 medical patients. Mean (+/-SE) Health Related Quality of Life scores were better (p < 0.05) in the surgical group (4+/-0.6 versus 21+/-1.4). More of the medical patients were dissatisfied (21.6% versus 5.9%). Short-Form 36 scores at followup were better (p < 0.05) in six of eight domains for surgical patients.nnnCONCLUSIONnHeartburn scores and global QOL scores were superior after laparoscopic fundoplication compared with medical management in this patient population. Laparoscopic fundoplication should be considered for patients who are dissatisfied with medical treatment.

Outcomes after minimally invasive reoperation for gastroesophageal reflux disease

BACKGROUNDnReoperative antireflux surgery is complex and traditionally performed by open methods. Increasingly, surgeons are performing minimally invasive reoperations. This report summarizes our experience with laparoscopic reoperative antireflux surgery (LRAS).nnnMETHODSnA retrospective review (1996 to 2001) identified 80 LRAS cases. Median age was 49 (22 to 80) years with 52 females and 28 males. Primary symptoms included heartburn (53%), regurgitation (22%), and dysphagia (25%). Detailed outcomes recorded at follow-up included heartburn severity using the Gastroesophageal Reflux Disease-Health Related Quality of Life scale (HRQOL) and SF36 physical (PCS) and mental (MCS) component summary scores.nnnRESULTSnLRAS was completed in 97.5% of cases (two conversions). The most common problems identified were mediastinal migration of the wrap in 48 (60%) and misplaced wrap in 11 (13.8%). LRAS operations included Collis-Nissen (42), Nissen (26), Toupet (six), and six others. Pyloroplasty was required in nine (11%). Complications occurred in 16 patients. These included nine minor gastric perforations (all repaired intraoperatively) and two reoperations for complications (1 patient with a bile leak and the second with a pyloroplasty site leak). Median length of stay was 2.5 days. Median follow-up was 18 (1 to 52) months; 18 (23%) required proton-pump inhibitors. Detailed outcomes were available in 50 patients. Mean PCS and MCS scores were 42 and 47, respectively (normals = 50). HRQOL scores were excellent in 35 (65%), satisfactory in 9 (17%), and poor in 10 (18%). Ten patients (18%) reported that they were dissatisfied.nnnCONCLUSIONSnLRAS can be performed safely with complication and success rates similar to open operations in a center with extensive laparoscopic experience.
