Abstract
BACKGROUND Recommendations for the use of specific anastomotic techniques are not available in laparoscopic bariatric surgery. Recommendation criteria should consider the rate of insufficiency, bleeding, tendency to stricture or ulceration as well as the impact on weight loss or dumping. OBJECTIVE This article gives a review of the available evidence on the anastomotic techniques of typical surgical procedures in laparoscopic bariatric surgery. MATERIAL AND METHODS The current literature was reviewed and is discussed regarding anastomotic techniques for Roux-en‑Y gastric bypass (RYGB), one-anastomosis gastric bypass (OAGB), single anastomosis sleeve ileal (SASI) bypass and biliopancreatic diversion with duodenal switch (BPD-DS). RESULTS Few comparative studies exist, except for the RYGB. In RYGB gastrojejunostomy, a complete manual suture was shown to be equivalent to a mechanical anastomosis. In addition, the linear staple suture showed slight advantages over the circular stapler in terms of wound infections and bleeding. The anastomosis technique of the OAGB and SASI can be performed entirely with a linear stapler or with suture closure of the anterior wall defect. There seems to be an advantage of manual anastomosis in BPD-DS. CONCLUSION Due to the lack of evidence, no recommendations can be made. Only in RYGB was there an advantage of the linear stapler technique with hand closure of the stapler defect compared to the linear stapler. In principle, prospective, randomized studies should be strived for.

Abstract
BACKGROUND Single-anastomosis duodeno-ileal bypass (SADI-S) is being proposed for obese patients with insufficient weight loss or weight regain after sleeve gastrectomy (SG), but limited information is available. The purpose of this study is to assess the safety and efficacy of SADI-S as a revisional surgery after SG, compared with standard duodenal switch (DS). METHODS Unicentric cohort study including all patients submitted to SADI-S and DS after failed SG in a high-volume institution, between 2008 and 2020. RESULTS Forty-six patients submitted to SADI-S and 55 to DS were included, 37.2 and 41.5 months after SG (p = 0.447), with initial BMI of 56.2 vs. 56.6 (p = 0.777) and 39.2 vs. 39.7 before revisional surgery (p = 0.675). All surgeries were laparoscopic. Clavien-Dindo > II complication rate was 6.5% for SADI-S and 10.9% for DS (p = 0.095), with no 90-day mortality. Follow-up at 2 years was available for 38 SADI-S' and 38 DS' patients, with total weight loss of 35.3% vs. 41.7% (p = 0.009), and excess weight loss 64.1% vs. 75.3% (p = 0.014). Comorbidities resolution for SADI-S and DS was: 44.4% vs. 76.9% for diabetes (p = 0.029) and 36.4% vs. 87.5% for hypertension (p = 0.006); with no differences for resolution of dyslipidemia (72.7% vs. 88.9%, p = 0.369) and obstructive sleep apnea (93.3% vs. 91.7%, p = 0.869). DS' patients required more extra nutritional supplementation. Three SADI-S patients needed conversion to DS, two for biliary reflux and one for weight regain. CONCLUSION After a failed SG, revisional DS permits better weight control and diabetes and hypertension resolution than SADI-S, at the expense of higher supplementation needs.

Abstract
The prevalence of gastroesophageal reflux disease (GERD) has mirrored the increase in obesity, and GERD is now recognized as an obesity-related comorbidity. There is growing evidence that obesity, specifically central obesity, is associated with the complications of chronic reflux, including erosive esophagitis, Barrett's esophagus, and esophageal adenocarcinoma. While fundoplication is effective in creating a competent gastroesophageal junction and controlling reflux in most patients, it is less effective in morbidly obese patients. In these patients a bariatric operation has the ability to correct both the obesity and the abnormal reflux. The Roux-en-Y gastric bypass is the preferred procedure.

Abstract
BACKGROUND Biliopancreatic diversion is a powerful bariatric procedure that relies on gastric restriction combined with a large malabsorptive component. This can lead to excessive side effects and/or weight loss. Despite this, long-term weight regain can also occur. OBJECTIVES To determine the rate of and options for revision in patients who experience excessive side effects and weight loss. To explore the revisional procedures available to overcome weight regain. METHODS A PubMed search was conducted of all reports published between 1979 and August 31, 2014. Series and case reports on revision or reversal after biliopancreatic diversion with duodenal switch (BPD/DS) or without (BPD) were included. RESULTS Revision rates for excessive malabsorption ranges from .5%-4.9% and 3%-18.5% after BPD/DS and BPD respectively. Revisions increase common channel by up to 150 cm. Reversal is necessary in .2%-7% of cases, with an increased risk when the common channel is ≤ 50 cm. In most instances, reversal (of the malabsorptive component only) is indicated after the revision failure. A proximal, side-to-side anastomosis between the biliopancreatic and alimentary limbs is the preferred option. Most reoperations are performed within 2 years of the initial procedure and for protein malnutrition in about half of the cases. Revision for insufficient weight loss is reported in .5%-2.78% of cases. Except inadequate channel lengths, little is to be gained by common channel shortening. Additional gastric restriction, which results in an average 9-14 kg weight loss, is another option. CONCLUSIONS Biliopancreatic diversion can be relatively easily revised to control excessive side effects and protein malnutrition. Early diagnosis is essential and warrants a close nutritional monitoring. In case of weight regain, limited results can be obtained by reducing the gastric volume provided the lengths of the small bowel channels are adequate.

Abstract
Severe obesity is associated with increased morbidity and mortality and represents a major health care problem with increasing incidence worldwide. Bariatric surgery, through its efficacy and improved safety, is emerging as an important available treatment for patients with severe obesity. Classically, bariatric surgery has been described as either a restrictive or a hybrid surgery, which is a combination of restriction and malabsorption. For most severely obese patients, bariatric surgery results in the remission of major obesity-related comorbidities including type 2 diabetes mellitus, sleep apnea, hypertension, and dyslipidemia. Thus, bariatric surgery reduces cardiovascular risk burden, and overall mortality risk. Early complications (< 30 days) after bariatric surgery were reported to be < 10% and tend to be lower in restrictive surgeries compared with hybrid surgeries. Most common early complications reported are gastric and anastomosis leak (1.6%-5.1%), bleeding (0.5%-3.5%), and pulmonary embolism (0.2%-1%). Long-term complications (> 30 days) might differ depending on the type of bariatric surgery. According to the type of surgery and the type of study, the 30-day operative mortality rates differ from 0.1% to 1.2%. Studies on postoperative outcomes, investigations on weight loss physiology, and mechanism of action after bariatric surgery provide a better understanding of the bariatric surgery metabolic benefits. In this article, we present an overview of bariatric procedures with their effects, including risks and benefits, on the severely obese patients' health. It provides evidence to support surgical treatment of severe obesity to achieve cardiovascular disease risk reduction in severely obese patients.

Abstract
The prevalence of morbidly obese individuals is rising rapidly. Being overweight predisposes patients to multiple serious medical comorbidities including type two diabetes (T2DM), hypertension, dyslipidemia, and obstructive sleep apnea. Lifestyle modifications including diet and exercise produce modest weight reduction and bariatric surgery is the only evidence-based intervention with sustainable results. Biliopancreatic diversion (BPD) produces the most significant weight loss with amelioration of many obesity-related comorbidities compared to other bariatric surgeries; however perioperative morbidity and mortality associated with this surgery are not insignificant; additionally long-term complications including undesirable gastrointestinal side effects and metabolic derangements cannot be ignored. The overall quality of evidence in the literature is low with a lack of randomized control trials, a preponderance of uncontrolled series, and small sample sizes in the studies available. Additionally, when assessing remission of comorbidities, definitions are unclear and variable. In this review we explore the pros and cons of BPD, a less well known and perhaps underutilized bariatric procedure.

Abstract
OBJECTIVE To establish evidence-based guidelines for best practices in pediatric/adolescent weight loss surgery (WLS). RESEARCH METHODS AND PROCEDURES We carried out a systematic search of English-language literature in MEDLINE on WLS performed on children and adolescents. Key words were used to narrow the field for a selective review of abstracts. Data were extracted, and evidence categories were assigned according to a grading system based on established evidence-based models. Eight pertinent case series, published between 1980 and 2004, were identified and reviewed. These data were supplemented with expert opinions and literature on WLS in adults. RESULTS Recommendations focused on patient safety, reduction of medical errors, systems improvements, credentialing, and future research. We developed evidence-based criteria for eligibility, assessment, treatment, and follow-up; recommended surgical procedures based on the best available evidence; and established minimum guideline requirements for data collection. DISCUSSION Lack of adequate data and gaps in knowledge were cited as important reasons for caution. Physiological status, comprehensive screening of patients and their families, and required education and counseling were identified as key factors in assessing eligibility for surgery. Data collection and peer review were also identified as important issues in the delivery of best practice care.

Abstract
BACKGROUND The biliopancreatic diversion with duodenal switch can be performed by different combinations of restriction and malabsorption. The aim of this study was to evaluate weight loss and potential side effects for two variants of the procedure. METHODS All patients eligible for a 2-year follow-up (n = 182) was included in the study. Thirty-five patients (group A) had a gastric remnant with a volume of approximately 200 ml, an alimentary limb (AL) of 250 cm, and a common channel (CC) of 100 cm, while 147 patients (group B) had a gastric remnant of 100-120 ml, an AL of 40%, and a CC of 10% of the small bowel length. Preoperative variables, such as body mass index (BMI), sex, age, and factors that might influence weight loss, and postoperative weight loss and side effects were registered and compared. RESULTS Preoperatively, the BMI was 50.6 in group A and 52.1 in group B (ns), with no difference in age, sex, or variables that might influence weight loss. At 2 years, the BMI was 33.1 in group A (n = 34) and 28.5 in group B (n = 119) with an adjusted difference in weight loss of 5.6 BMI units between the groups (p < 0.001). Vitamin D status was also better in group B than in group A at follow-up, while there was no difference in side effects. CONCLUSIONS Patients with a remnant stomach of 100-120 ml, and AL and CC with individually adapted lengths had a larger weight loss and better vitamin D status postoperatively without an increase in side effects.

Abstract
INTRODUCTION The duodenal switch (DS) technique is considered to be complex surgery with a series of metabolic complications due to its malabsorptive character. For these reasons, it has not been extensively used by bariatric surgeons. Despite this, we consider it to be a suitable technique for the grossly obese. PATIENTS AND METHODS A retrospective study was performed on 110 patients with morbid obesity operated on using the DS technique and who were followed up for a minimum period of four years after surgery. We evaluated the weight loss, the outcomes of the comorbidities, and the metabolic complications. RESULTS The loss of excess weight was greater than 50% in 75% of the patients after 12 months follow up. The comorbidities suffered by 68 patients (75.5%) were completely resolved. The most frequent metabolic complications were iron (Fe) deficiency and an increased parathyroid hormone (PTH). CONCLUSIONS DS is a safe and effective technique for the treatment of morbid obesity, with good weight loss results, a high percentage of remission of the comorbidities, a similar morbidity and mortality to other techniques, and with correctable nutritional changes, and thus acceptable.

Abstract
BACKGROUND Biliopancreatic diversion with duodenal switch (BPD/DS) is one of the most effective procedures in terms of weight loss and durability. It is also one of the most complex and highest risk bariatric procedures. The authors report their initial experience with BPD/DS. METHODS A retrospective review of all patients undergoing BPD/DS was performed, including a descriptive analysis of demographics, operative data, complications, and outcomes. Results were also compared with those among a group of 100 patients undergoing laparoscopic gastric bypass (LGB). RESULTS Forty-three patients were identified. Mean preoperative body mass index was 52 kg/m(2), and 56% of patients had body mass indexes > 50 kg/m(2). Twenty (47%) were attempted laparoscopically, with 5 (25%) requiring conversion to open approach. Overall mean operative time was 269 minutes, with no significant difference between laparoscopic (256 minutes) and open (280 minutes). No major intraoperative complications occurred. Major postoperative complications included 4 gastric sleeve leaks, 2 small bowel obstructions, 1 intra-abdominal hemorrhage, and 1 duodenal stump leak. There was 1 death. Mean percentage excess body weight loss was 85% at 1 year. No patients developed severe malabsorptive symptoms or evidence of protein malnutrition. BPD/DS was associated with longer operative times and higher complication rates (P < .05 for both) compared with LGB but had significantly greater weight loss at 1 year (P < .05). CONCLUSION BPD/DS is a complex procedure associated with increased operative times, increased risk for conversion from laparoscopic to open approach, and higher postoperative complication rates. However, it results in significantly greater weight loss than LGB without major adverse nutritional impact.

Abstract
BACKGROUND Duodenal switch (DS) is one of the most effective techniques for the treatment of morbid obesity and its co-morbidities, with mortality rate <1%, but with 9.4% morbidity rates (6.5% due to leaks). In our experience, leaks of the staple-line after sleeve gastrectomy (SG) are the most frequent sites of fistula formation and conservative treatment usually takes a long time. We present our experience in the treatment of gastric leaks with coated self-expandable stents (CSES). METHODS 6 patients had gastric leaks at the gastroesophageal (GE) junction after SG or DS. One patient had a symptomatic gastro-bronchial fistula. Stents were placed by the interventional radiologist under fluoroscopic control and removed endoscopically. In one case, we used an uncoated Wallstent. In two patients, percutaneous microcoil embolization of the fistula was added. RESULTS The patient treated with the Wallstent required a total gastrectomy 6 months after placement of the uncovered stent. In the other 5 patients, coated stents were successfully removed and the gastric leaks completely sealed. CONCLUSIONS CSES are proposed as an alternative therapeutic option for the management of GE junction leaks in bariatric surgery with good results in terms of morbidity and survival.

Abstract
Morbid obesity is a worldwide pandemic. Medical problems associated with being obese include hypertension, diabetes, pulmonary restrictive disease, obstructive sleep apnea, and increased risk of cancer. In addition, there is a tremendous financial burden on society and the health care system to take care of these individuals. Bariatric surgery has proved to be a safe, effective means of sustained weight loss, which can lead to improvement or resolution of obesity-related medical conditions. Individuals who are morbidly obese represent a unique population requiring special consideration when presenting for medical care.

Abstract
At present, bariatric surgery is the only treatment that can achieve meaningful and sustainable weight loss for the millions of morbidly obese individuals. The current popular operative procedures (the Roux-en-y gastric bypass, laparoscopic adjustable gastric band, and the biliopancreatic diversion with or without duodenal switch) are all relatively safe and effective. However, all of these procedures, to variable degrees, alter the anatomy and physiology of the gastrointestinal tract. This fact, along with postoperative dietary changes, makes these patients vulnerable to a multitude of potential complications. As more and more patients undergo these procedures, an increasing number of clinicians will be asked to care for them. It is therefore imperative that all clinicians have a general understanding of the operative procedures and the potential problems these patients may develop. This article will describe these operative procedures and will discuss the more common consequences.

Abstract
BACKGROUND The vertical gastrectomy (VG) is the restrictive part of the technically difficult biliopancreatic diversion with duodenal switch operation (DS). The VG was originally conceived of as an independent operation-the first stage of a two-stage DS that would reduce mortality and morbidity in the high-risk superobese because of a shorter operating time and no anastomoses. This article presents two-year data after VG. METHODS Laparoscopic VG was performed in a nonrandomized fashion in obese patients that met the NIH criteria for bariatric surgery. By using 5-7 firings of 45-60-mm linear 3.5-mm GI staplers along a 32-Fr bougie, a greater-curvature gastrectomy is performed and a 60-80-ml gastric tube is created. VG was compared to adjustable Lap-Band placement, Roux-en-Y gastric bypass (RGB), and DS. RESULTS Between November 2002 and August 2005, 216 patients underwent VG. The mean age was 44.7 years (range = 16-64) and 173 (80%) were female. The mean preoperative weight and body mass index (BMI) was 302 +/- 77 lbs and 49 +/- 11 kg/m2, respectively. Of the 216 patients, 5 (2.3%) had a BMI > 80 kg/m2, 6 (2.8%) had a BMI of 70-80 kg/m(2), and 25 (11.6%) had a BMI of 60-70 kg/m2. The mean operative time was 66 +/- 11 min (range = 45-180) and the mean length of hospital stay was 1.9 +/- 1.2 days. Complications occurred in 20 (6.3%) patients (vs. 7.1% after Lap-Band). Leaks occurred in 3 (1.4%) VG patients, reoperations were performed in 6 (2.8%), and no conversions to open or deaths occurred. Weight loss on par with the DS and RGB was achieved with just the VG alone. CONCLUSION The VG operation is able to achieve significant weight loss comparable to the RGB and DS operations but with the low morbidity profile similar to that of Lap-Band placement.

Abstract
BACKGROUND Gastric restrictive procedures are widely used for the surgical treatment of morbid obesity. OBJECTIVE Our purpose was to determine the technical feasibility of endoscopic gastric reduction in a live porcine model. SETTING Acute experiments on 50-kg pigs under general anesthesia. DESIGN AND INTERVENTIONS After per-oral intubation, the endoscope was inserted into the stomach. A fishing line was sutured to the gastric wall along the fundus approximately 5 cm below the gastroesophageal junction with a prototype endoscopic suturing device (Olympus, Eagle Claw). Then the fishing line was tied to create a small proximal pouch. A flexible sheath was placed on one side of fishing line and additional knots were tied, forming a ring at the outlet of the gastric pouch. The ring was anchored to gastric wall with additional stitches, completing the gastric reduction. Then the animals were killed for postmortem examination. MAIN OUTCOME MEASUREMENTS The feasibility of endoscopic gastric reduction. RESULTS We performed 4 acute experiments. It required 12 to 14 stitches in each animal to create gastric reduction. There were no technical problems during the procedures. Postmortem examination demonstrated an approximately 30-mL gastric pouch separated from the rest of the stomach by the line of stitches. There were no complications during the procedure. LIMITATIONS We have not performed survival experiments to determine how long our gastric reduction will last. CONCLUSIONS Endoscopic gastric reduction is technically feasible on a live porcine model.

Abstract
CONTEXT AND OBJECTIVE Most bariatric surgical techniques include essentially non-physiological features like narrowing anastomoses or bands, or digestive segment exclusion, especially the duodenum. This potentially causes symptoms or complications. The aim here was to report on the preliminary results from a new surgical technique for treating morbid obesity that takes a physiological and evolutionary approach. DESIGN AND SETTING Case series description, in Hospital Israelita Albert Einstein and Hospital da Polícia Militar, São Paulo, and Hospital Vicentino, Ponta Grossa, Paraná. METHODS The technique included vertical (sleeve) gastrectomy, omentectomy and enterectomy that retained three meters of small bowel (initial jejunum and most of the ileum), i.e. the lower limit for normal adults. The operations on 100 patients are described. RESULTS The mean follow-up was nine months (range: one to 29 months). The mean reductions in body mass index were 4.3, 6.1, 8.1, 10.1 and 10.7 kg/m2, respectively at 1, 2, 4, 6 and 12 months. All patients reported early satiety. There was major improvement in comorbidities, especially diabetes. Operative complications occurred in 7% of patients, all of them resolved without sequelae. There was no mortality. CONCLUSIONS This procedure creates a proportionally reduced gastrointestinal tract, leaving its basic functions unharmed and producing adaptation of the gastric chamber size to hypercaloric diet. It removes the sources of ghrelin, plasminogen activator inhibitor-1 (PAI-1) and resistin production and leads more nutrients to the distal bowel, with desirable metabolic consequences. Patients do not need nutritional support or drug medication. The procedure is straightforward and safe.

Abstract
Laparoscopic duodenal switch gives a consistent excess weight loss of 70-80% with acceptable long-term nutritional complications. It is especially indicated for super-obese patients with a body mass index greater than 50 kg/m(2). A systematic review of the literature and results of open and laparoscopic duodenal switch is thoroughly presented. Also presented for the authors' surgical colleagues are some technical details concerning their preferred method. Meta-analysis now demonstrate a low mortality rate for the laparoscopic procedure close to 0.5%, and operative times close to 200 min. Laparoscopic duodenal switch is likely to increase in popularly for the treatment of morbid obesity, especially with the recent advent of laparoscopic sleeve gastrectomy for higher-risk patients.

Abstract
In the context of political, economic, and scientific anxiety around the 'epidemic' rise in obesity in the US, the social and historical forces engendering the medicalization of obesity have been widely discussed. However, the recent growth of bariatric-weight loss-surgery and the expanding presence of advertising for bariatric surgery on the Internet suggest the possible emergence of new loci and languages of medicalization. We sought to identify the nature and extent to which web advertising of bariatric surgery contributes to the medicalization of obesity by examining the design and textual content of 100 bariatric surgery center websites. We found that websites, through strategic use of text and images, consistently describe obesity as a serious disease that requires professional ascertainment and supervision, entails substantial individual suffering, and is remedied through the transformative yet low risk effects of bariatric surgery. In the process, social normalcy and risk reduction come to replace physical criteria as the basis for determining health. Further, websites draw upon contradictory discourses of medicalization; that is, they insist upon 'external' (e.g. genetics, environment) causes of obesity to legitimize surgical intervention while implicating individual behaviors in surgical failure. From this, we suggest that the economic and professional motivations underlying website advertisements for bariatric surgery may result in confusing messages being sent to prospective patients as well as the perpetuation of gendered notions of obesity and the entrenchment of health disparities.

Abstract
The duodenal switch provides excellent weight loss with preservation of good alimentation, even in the superobese. This is accomplished with acceptable operative mortality and minimal dietary limitations and metabolic sequelae. The results of the duodenal switch that are reported in the literature should remove any inhibitions that exist about the use of this procedure as treatment for patients who have morbid obesity. This article discusses the duodenal switch operation for morbid obesity.

Abstract
BACKGROUND Severe obesity is associated with important morbidity and increased mortality. The successes of lifestyle modifications and drug therapy have been partial and mostly unsustained in reducing obesity and its comorbidities. Bariatric surgery, particularly biliopancreatic diversion with duodenal switch reduces efficiently excess body weight and improves metabolic and cardiovascular functions. CASE PRESENTATION A 56-year-old man with severe clinical obesity underwent a biliopancreatic diversion with a duodenal switch after unsuccessful treatment with weight loss pharmacotherapy. He had diabetes, hypertension and sleep apnea syndrome and was on three medications for hypertension and two hypoglycemic agents in addition to > 200 insulin units daily. Eleven months after the surgery, he had lost 40% of his body weight. The lipid profile showed great improvement and the hypertension and diabetes were more easily controlled with no more insulin needed. The pseudonormalized pattern of left ventricular diastolic function improved and ventricular walls showed decreased thickness. CONCLUSION Biliopancreatic diversion may bring metabolic and cardiovascular benefits in severely obese patients from a cardiovascular perspective.

Abstract
OBJECTIVE To determine the safety and efficacy of the duodenal switch procedure as surgical treatment of morbid obesity. SUMMARY BACKGROUND DATA The longitudinal gastrectomy and duodenal switch procedure as performed for morbid obesity involves a 75% subtotal greater curvature gastrectomy and long limb suprapapillary Roux-en-Y duodenoenterostomy. This results in a restricted caloric intake and diversion of bile and pancreatic secretions to induce fat malabsorption. Broad acceptance of this procedure has been impeded because of concerns that the malabsorptive component may produce serious nutritional complications. METHODS Review of data collected prospectively from all patients who underwent duodenal switch as the primary surgical treatment of morbid obesity at a single institution during the 10-year period beginning September 1992. Operative morbidity and mortality, weight loss, volume of food intake, and bowel function were recorded. Sequential measurements of serum albumin, hemoglobin, and calcium levels were obtained to assess metabolic function and nutrient absorption. RESULTS Duodenal switch was performed as the primary operation in 701 (81%) of a total 863 patients undergoing bariatric surgery during the period of study. The average body mass index (BMI) was 52.8 (range, 34-95). Perioperative mortality was 1.4%, and morbidity (including leaks, wound dehiscence, splenectomy, and postoperative hemorrhage) occurred in 21 patients (2.9%). Weight loss averaged 127 pounds at 1 year, 131 at 3 years, and 118 at 5 or more years (% EBWL of 69%, 73%, and 66%, respectively). The mean number of bowel movements was fewer than 3 per day. Patients reported and maintained a mean restriction of 63% of their preoperative intake (approximately 1600 calories), with no specific food intolerance, at 3 or more years follow-up. At 3 years, serum albumin remained at normal levels in 98% of patients, hemoglobin in 52%, and calcium in 71%. No patients reported dumping, and marginal ulcers were not seen. CONCLUSIONS The longitudinal gastrectomy with duodenal switch is a safe and effective primary procedure for the treatment of morbid obesity. It has the advantage of allowing acceptable alimentation with a minimum of side effects while producing and maintaining significant weight loss. These results are achieved without developing significant dietary restrictions or clinical metabolic or nutritional complications.

Abstract
Surgery for massive super obesity is a formidable challenge. No existing open or laparoscopic procedure reduces BMI below 30 from a starting point above 55. Laparoscopic adjustable gastric banding has been used to treat 76 massive super obese patients with a BMI > 60 kgs/m2. Median weight was 193 kgs +/-34.7 kgs (154-335 kgs). Five patients had a BMI > 100 kgs/m2. There was neither mortality nor pulmonary emboli. hospital stay was 3 days (1-6 days). Excess weight loss was 46.69 +/-10.5 at 1 year; 59.14 +/- 11.7% at 3 years and 61 +/- 15.1% at 5 years. At 2 years, 84% of the patients had greater than 50% excess weight loss and this was maintained at 3, 4, and 5 years. BMI fell from 69 +/- 6.2 to 49 +/- 7.73 at 1 year to 37 +/- 4.45 at 3 years and this was maintained at 4 and 5 years. BMI in 13 patients with > 5 year follow up was 35.09 +/- 53 kgs/m2 (27-44). Weight loss with laparoscopic adjustable gastric banding in this group of massive super obese patients has been similar to all other surgical techniques with reduction of BMI from 69 to 33 kgs/m2 at 3 years. The relative safety of the Lapband avoids bowel surgery in these very big patients, suggesting that laparoscopic adjustable gastric banding is a valid surgical approach to these difficult patients.

Abstract
Morbid obesity is defined as obesity with a body mass index >/=40, or >/=35 with secondary serious diseases. Conservative medical therapies in these individuals generally fail to sustain weight loss. Thus, surgical operations have evolved which are based on gastric restriction and/or malabsorption. Historically, the intestinal bypass operation was followed by the gastric bypass operation (in some instances combined with intestinal bypass) or by the gastric restriction operations (gastroplasty or gastric banding). Laparoscopic techniques are now being used for these operations, but require surgical expertise in both the bariatric operations and advanced laparoscopic skills. All operations may have complications, but these occur in a very small percent. Postoperative follow-up and nutritional surveillance are mandatory. The operations result in significant weight loss, and the current operations have a mean lasting weight loss of about 50 percent of excess body weight, with improvement or resolution of most obesity-associated conditions. There is evidence that even modest to moderate weight loss in these individuals has significant medical benefit.
