Background: Roux-en-Y gastric bypass (RYGBP) is rarely performed in Italy because it involves gastric exclusion. RYGBP with the stomach partitioned by an adjustable gastric band has been previously described. We have developed a functional RYGBP (FRYGBP) where an adjustable band allows access from a stapled gastric bypass pouch into the distal stomach. Methods: From October 2001 to May 2002, 16 patients underwent FRYGBP. A 30-cc vertical gastric pouch was fashioned by a 25-mm circular and 90-mm four-row stapler as in the Mason VBG. A hand-sewn retrocolic gastroenterostomy with 150-cm Roux and 30-cm afferent limbs completed the operation. The pouch outlet was encircled distal to the gastrojejunostomy by a non-inflated adjustable gastric band. The bands were inflated at 1 month during barium swallow, to demonstrate occlusion of the gastro-gastric outlet and patency of the gastrojejunostomy. Results: There was no operative mortality. After 1 year, mean percent excess BMI loss (%EBMIL) was 71.2 ± 16.2% (SD), and gastroscopy of the bypassed stomach was possible on 81% of the patients. There were three asymptomatic late complications (19%): two band erosions, converted to RYGBP, and one stenosis of the gastro-gastric outlet. Conclusion: FRYGBP thus far has been effective and allows the study of the excluded stomach. This ongoing study will undergo long-term evaluation.  相似文献

The technique of gastric bypass has undergone an evolution over the last 20 years, although it is often individualized based on surgeon preference. Whereas many surgeons divide and separate the gastric pouch from the distal bypassed stomach, some surgeons choose to staple, but not cut and separate the pouch. Staple-line failure resulting in a gastrogastric fistula and weight regain is a worrisome complication. We discuss a case of a patient with an obvious staple-line failure, which resulted in complete weight regain. She underwent laparoscopic repair and was discharged on postoperative day 1. Laparoscopic repair of a staple-line disruption after an open uncut gastric bypass is feasible. Presented at the World Congress of the International Federation for the Surgery of Obesity, Sydney, Australia, August 31, 2006.  相似文献

Background: The complications of the gastric pouch in gastric bypass surgery are well known. Since the first report of this surgery 30 years ago, new technical aspects that make it safer and more effective have been implemented. Methods: As a modification of gastric bypass, the authors have performed 305 vertical banded gastroplasty-gastric bypass procedures. Two groups of patients underwent the procedure: Group I (n = 206) without a limb of jejunum interposed between the gastric pouch and the excluded stomach, and Group II (n = 99) with a limb of jejunum interposed between the pouch and the stomach. The results regarding excess weight loss and complications of the gastric pouch during the first year after surgery were compared. Results: Age, sex, initial weight, body mass index, and percentage of ideal weight were similar in both groups. Excess weight loss was also similar. The complications in Group I were 1 leak, 3 left subphrenic abscesses, 2 erosive gastritis with bleeding, 1 stenosis of the gastrojejunostomy, 1 perforated ulcer, and 4 marginal ulcers with bleeding. Two patients in Group II developed bleeding from the staple-line. Conclusions: These preliminary data suggest that complications of the gastric pouch can be reduced by interposing a limb of jejunum between the pouch and the excluded stomach. This is an early experience; long-term results are pending.  相似文献

Vertical Banded Gastroplasty--Gastric Bypass: preliminary report   总被引:2,自引:2,他引:0  
Vertical banded gastroplasty-gastric bypass is a surgical technique combining the advantages of the vertical banded gastroplasty with those of gastric bypass. The procedure was performed on 148 morbidly obese individuals: 83% were female and 17% were male. Ages ranged from 15 to 64 years, with a mean age of 35. Mean percentage weight was 215% of ideal. The vertical banded gastroplasty is constructed by creating a 10 cc vertical pouch along the lesser curvature with a 5.5 cm supporting band. The pouch is fashioned in a way that the lower portion is free and mobile. This free segment of stomach is anastomosed by triangulation to a Roux-en-Y loop of jejunum, which is brought up in a retrocolic, retrogastric fashion. With 100% follow-up in the 19 patients who have reached 1 year, average excess weight loss has been substantial. There was one early postoperative complication requiring surgery. Two patients required late revisional operations. Vertical banded gastroplasty-gastric bypass is a relatively simple procedure to perform and has a low rate of complications. Gastric bypass in combination with a small banded pouch along the lesser curvature should result in substantial and permanent weight loss.  相似文献

Gastric carcinoma in the bypassed stomach after Roux-en-Y gastric bypass (RYGBP) is rare but has been reported. The time from RYGBP to the presentation of cancer has ranged from 5 to 22 years postoperatively in the literature. A major concern with the current technique for RYGBP is the exclusion of the bypassed stomach and difficulty in surveillance. Thus, some surgeons recommend routine preoperative evaluation via endoscopy. Although most findings are benign, abnormalities are frequently discovered during screening endoscopy in bariatric surgery patients. We present a 45-year-old woman who was discovered to have disseminated gastric cancer involving the excluded bypassed stomach following an open RYGBP. Preoperative upper endoscopy was not performed. This case illustrates the importance of endoscopic evaluation prior to RYGBP and signifies the need for a high index of suspicion in order to recognize this problem at an early stage.  相似文献

Background: The training and credentialing of surgeons for laparoscopic bariatric surgery is controversial. We sought to determine if there is an association between surgeons' practice and choice of open or laparoscopic bariatric surgery. Methods: Members of the ASBS were surveyed via email. Associations were tested with Cochran-Mantel-Haenszel or Pearson's chi-square. Results: 104/472 members responded; 65% were in private practice; 47% did 1-5 operations/week, 48% offered open procedures only, and 76% undertook gastric bypass. Respondents believe that laparoscopic procedures: should mimic open ones (77%), are safe (63%), should be evaluated by clinical trials (48%), and that expertise in bariatric surgery is more important than laparoscopic experience. 75% believe that courses and preceptorships are important. Regarding laparoscopic operations, surgeons doing only open procedures believe that: 1) the ASBS should be the main credentialing body; 2) surgeons should do >25 open before laparoscopic ones; and 3) clinical trials are needed (P<0.02, all). Surgeons with laparoscopic training or practices believe that laparoscopic surgery is safe and effective (P<0.002). Both laparoscopic and open surgeons believe bariatric surgeons should be the only surgeons doing laparoscopic bariatric procedures (P<0.008). Conclusions:There is consensus that laparoscopic bariatric surgery should be undertaken only by surgeons with strong interest in bariatric surgery. Laparoscopic bariatric surgeons should incorporate lessons learned from open surgery. Both laparoscopic and open bariatric surgeons should seek added expertise via courses and preceptorships.The skepticism of surgeons with 'open' practices could be addressed by clinical trials. The ASBS should maintain its leadership position and foster emerging technologies.  相似文献

Gallbladder Management in Obesity Surgery   总被引:4,自引:0,他引:4  
Background: In the 1980s, some surgeons recommended routine cholecystectomy for patients undergoing bariatric surgery.This was based on the high prevalence of gallstones in the obese and concern that rapid weight loss would increase the risk of gallbladder disease. Others recommended waiting for a lower weight and a definite need.With increasing prevalence and severity of obesity and increased use of gastric reduction surgery for weight control, it seemed appropriate to review the current standard of care for cholecystectomy.A survey was also made of ursodeoxycholic acid usage for prevention of gallstone formation. Methods: Data collected from active contributors for the 28th Report of the International Bariatric Surgery Registry (IBSR) were examined. Two questionnaires were also sent to members of the American Society for Bariatric Surgery (ASBS). The first (Q1) asked about the indications for cholecystectomy. The second (Q2) asked about ursodeoxycholic acid usage for prevention of gallstone formation during rapid weight loss following surgical treatment of obesity. Results:There has been an increase in concurrent cholecystectomy during the last 15 years. Some of this is due to a shift from simple gastric restrictive operations to gastric bypass with gastric restriction. When the most extensive bypass of intestine is used, as in distal Roux-en-Y gastric bypass (RYGBPX) or biliopancreatic diversion with a duodenal switch (BPD-DS), all patients were reported to have undergone cholecystectomy. Only 30% of surgeons performing standard Roux-en-Y gastric bypass (RYGBP) remove normal-appearing gallbladders. Ursodeoxycholic acid is used to prevent gallstone formation in one-third of patients when a normal-appearing gallbladder is left in place. Conclusions: Prophylactic cholecystectomy is left to the discretion of the surgeon when RYGBP is used. There has been an increase in cholecystectomy and malabsorptive operations during the last 15 years.When most of the small bowel is bypassed, all remaining gallbladders are removed. For patients with simple restriction operations, normal-appearing gallbladders are usually left in place. Urso-deoxycholic acid during rapid weight loss for prevention of gallstone formation is used in one-third of patients with remaining gallbladders.  相似文献

Because of regain of weight to BMI 37.1 kg/m2 6 years after a VBG, a 41-year-old female now underwent revision to divided Roux-en-Y gastric bypass, performed laparoscopically. 12 days postoperatively, she started bleeding from the main stomach, and CT scan revealed that the bypassed stomach was distended with clot. She was treated conservatively and stopped bleeding. Upper GI series 2 weeks postoperatively revealed a large gastrogastric fistula between the tiny pouch and the bypassed stomach. We initially planned to close the fistula. However, upper GI series 2 months and 4 months postoperatively showed no sign of gastrogastric fistula, and proton pump inhibitors were stopped. At 1 year after gastric bypass, our patient has had good weight loss.  相似文献

Background: The authors present a new restrictive and malabsorptive operation for treatment of morbid obesity, called vertical isolated gastroplasty (VIG). Methods: From Feb 2004 to May 2005, 30 patients with BMI ≥40 kg/m2 or >35 kg/m2 with co-morbidities underwent VIG via laparoscopy or laparotomy. The technique consisted in creation of a gastric tube preserving pylorus, and a Roux-limb of 300 cm to the bypassed stomach with the division 30 cm distal to the ligament of Treitz. Excess weight loss (EWL), BMI, complications and co-morbidities were assessed. Results: BMI and average preoperative weight were 41.2 kg/m2 and 110.7 kg, respectively. At 12 months postoperatively, BMI and average weight were 23.4 kg/m2 and 65.1 kg, respectively, with EWL 90.2%. None of the patients presented dumping. Improvement in co-morbidities was >90%. Complications consisted of: 1 dehiscence of gastric sutureline, 1 hemoperitoneum, 1 gastroenterostomy ulcer, 1 anemia of undetermined cause, and 3 cholelithiasis. There was no mortality. Conclusion: VIG has thus far been safe and effective, with the same results as other bariatric operations. VIG has certain advantages, such as lack of dumping and lack of clinically significant stenosis of the gastroenterostomy, which can occur with other techniques. Because a duodenal bypass is not performed, it allows physiologic absorption of iron and diagnostic and/or therapeutic access to the ampulla of Vater.  相似文献

Mucosal alterations after vertical banded Roux-en-Y gastric bypass have not been clearly evaluated. The aim of this paper was to analyze the histological findings and the presence of Helicobacter pylori in the excluded stomach. Forty consecutive patients who underwent Roux-en-Y gastric bypass longer than 36 months were selected for double-balloon enteroscopy. The excluded stomach was reached in 35/40 patients (88%). Morphological alterations were analyzed through hematoxilin and eosin and the presence of H. pylori was confirmed with Giemsa staining. Thirty patients (86%) were female, and the mean age was 43 years old. The mean postoperative time was 78 months (36-110 months). Histologically, all patients had chronic gastritis in the bypassed stomach, with pangastritis in 33/35 (94%). Five cases (5/35, 14%) presented atrophy and four of them also had intestinal metaplasia. Helicobacter pylori was detected in 7/35 (20%) of the excluded stomach and in 12/35 (34%) of the functional pouch. All patients positive for H. pylori in the excluded stomach were also positive in the functional pouch, p = 0.0005. Helicobacter pylori is still present in the excluded stomach after Roux-en-Y gastric bypass and might be considered for treatment. Histological findings indicated high prevalence of atrophy and intestinal metaplasia in this selected population.  相似文献

Laparoscopic Roux-en-Y gastric bypass (RYGB) is currently the preferred surgical procedure to treat morbid obesity. It has proven its effects on excess weight loss and its positive effect on comorbidities. One of the main issues, however, is the post-operative evaluation of the bypassed gastric remnant. In literature, cancer of the excluded stomach after RYGB is rare. We describe the case of a 52-year-old woman with gastric linitis plastica in the bypassed stomach after Roux-en-Y gastric bypass, diagnosed by means of laparoscopy and Single-Balloon enteroscopy, and it is clinical importance. Linitis plastica of the excluded stomach after RYGB is a very rare entity. This case report shows the importance of long-term post-operative follow-up, and the importance of single-balloon enteroscopy for visualization of the bypassed stomach remnant, when other investigations remain without results. This case report is only the second report of a linitis plastica in the bypassed stomach after Roux-en-Y gastric bypass.  相似文献

Background: This study examined the current practice of bariatric surgeons and their colleagues regarding patients with binge eating disorder (BED) and night eating syndrome (NES) who present for Roux-en-Y gastric bypass (RYGBP) for obesity. Method: We conducted a 9-item internet survey of American Society for Bariatric Surgery (ASBS) members. For each item, the numbers of respondents endorsing each possible response, including "Other" and "Unknown or not applicable," were tabulated, and percentages of the total sample of respondents were calculated. Results: Most respondents' screening process included mental health (82.0%) and nutritional (78.0%) evaluations. Most inquired about binge eating (88.0%) and other eating disturbances (83.3%), while fewer respondents (52.7%) screened for night eating. Management of patients with eating disorders varied widely. For patients with binge eating, 20.0% of respondents proceeded with surgery, 2.7% recommended against surgery, and 27.3% postponed surgery, with the remainder (50.0%) reporting that their management varied. For night eating and other eating disturbances, responses were similarly diverse. Respondents who postponed surgery reported a wide range of estimates of how often patients with eating disorders follow through with treatment for their eating problem and return for surgery: 16% (always/almost always), 36% (usually), 24% (sometimes), 12% (occasionally), and 12% (never/almost never). Conclusion: Although bariatric surgeons commonly screen for eating disorders such as BED, there are limited empirical data and no consensus regarding the optimal management of these patients.  相似文献

BackgroundThe use of circular staplers with a low staple height is associated with a lower risk for complication when used to construct the gastroenterostomy in laparoscopic gastric bypass surgery. The influence of staple height on outcome when using linear staplers has not been studied.ObjectivesTo investigate the influence of staple height when constructing the gastric pouch and gastroenterostomy using a linear stapler in laparoscopic gastric bypass surgery.SettingNationwide, Sweden.MethodsA retrospective, register-based cohort study, including all primary laparoscopic gastric bypass surgical procedures in Sweden registered in the Scandinavian Obesity Surgery Registry from January 2010 until January 2017, where linear staplers were used to construct the gastric pouch and the gastroenterostomy. Low stapler heights (closed height ≤1.0 mm) were compared with higher stapler heights (closed height ≥1.5 mm). The main outcome was postoperative complication within 30 days of surgery.ResultsWithin the study period, 27,975 patients were identified from the Scandinavian Obesity Surgery Registry. A closed staple height ≥1.5 mm was associated with higher risk for postoperative complication within 30 days of surgery compared with lower staple height. The risk was greater when used to construct the gastric pouch (adjusted odd ratio 1.30, 95% confidence interval 1.17–1.44, P < .001) as well as when constructing the gastroenterostomy (adjusted odd ratio 1.32, 95% confidence interval 1.20–1.45, P < .001).ConclusionThe use of low staple height for construction of the gastric pouch and gastroenterostomy in laparoscopic gastric bypass surgery was associated with lower complication rates.  相似文献

The Fobi-Pouch operation (FPO) for obesity is the product of clinical trials, more than 15 years of personal clinical experience and information gathered from publications, scientific meetings, and personal communications with other bariatric surgeons. The essence of the operation is the small vertical pouch (< 25 ml), an externally supported stoma, the interposed Roux-en-Y limb, the gastrostomy and the bypassed stomach marker to facilitate percutaneous transabdominal access to the bypassed segment. Patients undergoing this operation are usually given bowel prep the day before the operation, admitted the morning of the operation and started on subcutaneous heparin, prophylactic antibiotic and hydration. Antithrombotic sequential compression devices are regularly used. The hospital stay is usually 4 days. Our results and those of other surgeons who have used this modification substantiate the rationale for the modifications entailed in the FPO. Our longer-term experience and results are being compiled for publication.  相似文献

Background:We developed the laparoscopic gastric bypass in 1993 and first reported the technique and results in 1994. The technique for the gastroenterostomy was derived from the method used in the percutaneous endoscopic gastrostomy tube placement. Some have questioned the safety of this technique, and alternatives have been proposed. Method: Prospectively, we have followed and recorded the results of our laparoscopic patients. To date we have performed over 1,400 laparoscopic gastric bypass operations using the same technique of anvil placement: pulling the anvil down from the mouth to the stomach pouch with a percutaneously placed wire. All patients underwent upper GI endoscopy following the anvil placement, and a water-soluble upper GI series was obtained on the first postoperative day. Results: There have been no esophageal injuries in the first 1400 patients on whom this technique was done. Conclusion:The percutaneous pull-wire technique is a safe and effective method to place the 21-mm circular stapler anvil for the performance of a laparoscopic gastroenterostomy  相似文献

Background Mechanical restriction, malabsorption, and hormonal changes appear to play a role in weight loss after Roux-en-Y gastric bypass (RYGBP). This investigation chose to investigate one aspect of the restrictive role of gastric bypass: the pouch size. Our hypothesis was that a small pouch size with no fundus after laparoscopic RYGBP (LRYGBP) would lead to greater loss of excess weight and weight loss success. Methods Upper gastrointestinal radiological (UGI) studies were retrospectively reviewed by three blinded experts (2 bariatric surgeons and 1 expert radiologist), to determine pouch size and fundus size. The following grading system was utilized: Size I - smaller than average pouch, Size II - average pouch, Size III - larger than average pouch, and Size IV - over 3 times the size of an average pouch. Fundus 0 - no fundus appreciated, Fundus I - slight amount of fundus barely noted, Fundus II - fundus noted, Fundus III - large amount of fundus noted, and Fundus IV - majority of the pouch was fundus. Percentage of excess weight loss (%EWL) and successful weight loss (A. >50% EWL, B. within 50% of ideal body weight, C. loss of >25% of preoperative weight) were calculated. Results There were 59 patients in this study with 97% follow-up of >1 year. No Size IV or Fundus IV were noted. There were no statistically significant differences between in %EWL or success for either pouch size or fundus size. Conclusions While there may be a trend for the mean %EWL to be lower with larger pouches and larger amounts of fundus, no significant differences were found. Larger pouches and the presence of fundus (within reason) still result in a high rate of success after LRYGBP.  相似文献

Background: Since the 1980s, bypass operations have been largely replaced by gastric restrictive operations. One of the most commonly performed operations for gastric restriction is vertical banded gastroplasty (VBG). However, the results are often disappointing. Adjustable gastric banding (AGB) is a viable alternative to VBG, and the ability to perform this surgery laparoscopically makes it an attractive option for patients in need of revisional surgery. It allows for refashioning of the gastric pouch in patients with a dilation of the pouch or disruption of the staple line. Methods: A total of 48 patients were referred to our center due to post-VBG weight gain. All patients underwent preoperative evaluation to determine the cause for failure of the operation. All patients found suitable for revisional surgery underwent laparoscopic placement of an adjustable band. Results: All but one of the operations were completed laparoscopically; one patient required conversion to open surgery prior to band placement via laparoscopy. This patient needed a blood transfusion. Postoperative band erosion occurred in one patient; laparoscopy surgery was used successfully for removal of the band and suturing of the stomach. Conclusions: Our short-term results indicate that revisional operation for morbid obesity using laparoscopic AGB is a safe procedure when performed cautiously. It enables early patient mobilization and discharge with good functional results and fewer perioperative complications.  相似文献

Background: Laparoscopic gastric bypass and vertical banded gastroplasty are two procedures used in the treatment of morbid obesity. The authors describe alternative techniques of laparoscopic distal gastric bypass as a modification of the Scopinaro procedure, which were used experimentally in a porcine model. Methods: Five pigs were used. The laparoscopic procedure was performed with the pigs under general anesthesia after pneumoperitoneum had been achieved. Five or six trocars were used. One port was converted from 12 to 33 mm, and all the other ports were 10-11 mm. The initial surgical technique was similar to that used by others for laparoscopic gastrectomy, except that atraumatic ultracision was used for all the dissection. The stomach was stapled with a linear cutter stapler (Endopath, 31 mm) to create a 50-ml pouch. The ileum was divided with a linear cutter-stapler (Endopath, 31 mm) or ultracision cautery. A long length of ileum was positioned between the stomach pouch and the jejunoileostomy. Only 50-70 cm of terminal ileum was preserved as a common channel. In three animals, the circular stapler (ILS, 21 mm) was used to produce an end-to-side anastomosis. In one animal, two purse-string sutures were handsewn in the ileum and jejunum stumps, and in another two animals, two endoloops were used for the anvil. In two animals, the linear stapler was used to form a side-to-side pouch stomach-ileum and jejunoileostomy anastomosis. In other animals, the two types of anastomosis have been combined. All animals were killed after surgery so that the anastomoses could be evaluated for size and integrity. Results: In all animals, with the circular and linear stapler, both 21 and 13-15 mm anastomoses were intact. Conclusion: Distal gastric bypass is feasible laparoscopically, with intact anastomoses.  相似文献

Gastric bypass is the preferred operation for treatment of morbid obesity on many services. The evaluation of the excluded stomach is always difficult and a matter of concern for the attending physician. There are only four reported cases of gastric cancer in the distal stomach after gastric bypass. We report a 57-year-old man who had intestinal metaplasia at the time of the Roux-en-Y gastric bypass 4 years ago and now developed an aggressive carcinoma in the bypassed stomach.  相似文献

Background: Prosthetic devices have been used in bariatric operations to control the outlet of the gastric pouch and thus maintain weight loss. A complication of these prostheses is erosion or migration into the gastric lumen. The transected banded vertical gastric bypass (TBVGBP) is one of the modifications of gastric bypass. This modification has a silastic ring placed around the pouch to form the stoma. Method:The records of patients with band erosion (BE) after this operation were reviewed, to determine the incidence, etiology, management and outcome during a 9-year period. Results: From May 1992 through May 2001, 2,949 primary and secondary TBVGBP were performed through the Center for Surgical Treatment of Obesity, utilizing 3 hospitals. 48 patients (1.63%) were documented to have BE: 40 documented by us and 8 by subsequent treating surgeons or at other facilities. Presenting symptoms were weight regain (18), stenosis or obstruction (17), pain (9), bleeding (7), and 5 were incidental findings. Some patients presented with more than one symptom. 8 were treated expectantly with spontaneous extrusion of the band. 16 bands have been removed endoscopically in 14 patients. 26 patients had open surgical revision, with 12 having band removal only and 14 band removal and revision of either the gastroenterostomy with or without band replacement or conversion to a distal Roux-en-Y gastric bypass (DRYGBP). Two patients who had revision to DRYGBP were re-revised to a longer common limb because of protein malnutrition. Three patients who had revision of the gastroenterostomy with band removal and replacement developed leaks that were managed non-surgically. Two of these re-eroded and the band was removed endoscopically with a subsequent revision to a DRYGBP.There was no death due to BE. Conclusion: BE is an uncommon complication of TBVGBP.Infection, previous bariatric operations and surgical technique play a role in BE. BE is best managed by endoscopic removal but can be treated expectantly or by open surgical intervention. Band removal without replacement or revision to DRYGBP may result in weight regain.  相似文献
