Abstract
The incidence of type 2 diabetes (T2D) is increasing at an alarming rate worldwide. Bariatric surgical procedures, such as the vertical sleeve gastrectomy and Roux-en-Y gastric bypass, are the most efficient approaches to obtain substantial and durable remission of T2D. The benefits of bariatric surgery are realized through the consequent increased satiety and alterations in gastrointestinal hormones, bile acids, and the intestinal microbiota. A comprehensive understanding of the mechanisms by which various bariatric surgical procedures exert their benefits on T2D could contribute to the design of better non-surgical treatments for T2D. In this review, we describe the classification and evolution of bariatric surgery and explore the multiple mechanisms underlying the effect of bariatric surgery on insulin resistance. Based upon our summarization of the current knowledge on the underlying mechanisms, we speculate that the gut might act as a new target for improving T2D. Our ultimate goal with this review is to provide a better understanding of T2D pathophysiology in order to support development of T2D treatments that are less invasive and more scalable.

Abstract
Background Concerns for the possibility of an excessive loss of fat-free mass (FFM) and resting metabolic rate (RMR) after bariatric surgery, such as Roux-en-Y gastric bypass (RYGB) and duodenal switch (BPD/DS), have been raised. Objectives This study aims to examine body composition and RMR in patients after RYGB and BPD/DS and in non-operated controls. Methods Body composition and RMR were studied with Bod Pod and indirect calorimetry in weight-stable RYGB (n = 15) and BPD/DS patients (n = 12) and compared with non-operated controls (n = 17). All patients were 30–55 years old and weight stable with BMI 28–35 kg/m2. Results FFM% was 58% (RYGB), 61% (BPD/DS), and 58% (controls). Body composition did not differ after RYGB and BPD/DS compared to controls, despite 27 and 40% total body weight loss, respectively. No difference in RMR or RMR/FFM was observed (1539, 1617, and 1490 kcal/24 h; and 28.9, 28.4, and 28.8 kcal/24 h/kg). Conclusion Weight-stable patients with BMI 28–35 kg/m2 after RYGB and BPD/DS have a body composition and RMR similar to that of non-operated individuals within the same BMI interval.

Abstract
Objective The aim of this study was to evaluate the Laparoscopic Sleeve Gastrectomy (LSG) with simultaneous crural repair in treatment of morbid obesity associated with gastroesophageal reflux disease. Methods This prospective observational study was carried out from September 2012 to July 2016 in Al-Azhar University Hospital (Egypt). The study was conducted on 53 patients, 14 males (26.4%) and 39 females (73.6%) with the mean age 36.2 years (range 18–52 years), presenting with morbid obesity and reflux disease either symptomatic patients or asymptomatic (Endoscopic & Manometric), their mean Body Mass Index (BMI) was 50.1 kg/m2 (range 40–62 kg/m2), who underwent LSG and antireflux procedure (crural repair). Results Excess weight Loss (EWL); the mean EWL at 6 months postoperatively was 46.3%, at 12 months was 54%, and at 18 months was 61%. Also, we found that, preoperative co-morbidities are resolved by 53% and improved by 23%. Reflux symptoms were absent in 30 patients (56 %), improved in 14 patients (26.4 %), but persistent in 7 patients (13.2 %). Conclusion Laparoscopic crural closure, during LSG, represents a valuable option for the treatment of morbid obesity and gastroesophageal reflux, and can result in favorable outcomes in terms of weight loss and gastroesophageal reflux disease (GERD) symptoms control.

A retrospective comparison of biliopancreatic diversion with duodenal switch with single anastomosis duodenal switch (SIPS-stomach intestinal pylorus sparing surgery) at a single institution with two year follow-up. Surg Obes Relat Dis 2016; 13:415-422. [PMID: 28089438 DOI: 10.1016/j.soard.2016.11.020] [Citation(s) in RCA: 52] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2016] [Revised: 11/22/2016] [Accepted: 11/24/2016] [Indexed: 01/17/2023]
Abstract
BACKGROUND The traditional duodenal switch is performed using a Roux-en-Y configuration. This procedure has proven to be the most effective procedure for long-term weight loss and co-morbidity reduction. Recently, stomach intestinal pylorus sparing surgery (SIPS) has been introduced as a simpler and potentially safer variation of the duodenal switch (DS). It is a single anastomosis end-to-side proximal duodeno-ileal bypass with a sleeve gastrectomy. In this study, we compare our outcomes between biliopancreatic diversion with duodenal switch (BPD-DS) and SIPS at 2 years. SETTING This is a retrospective analysis from a single surgeon at a single private institution. METHODS We analyzed data from 182 patients retrospectively, 62 patients underwent BPD-DS while 120 other patients underwent SIPS between September 2011 and March 2015. A subset analysis was performed comparing data from both procedures to evaluate weight loss and complications. RESULTS Of 182 patients, 156 patients were beyond 1 year postoperative mark and 99 patients were beyond 2 year postoperative mark. Five patients were lost to follow-up. None of our patients had complications resulting in death. BPD-DS and SIPS had statistically similar weight loss at 3 months but percent excess weight loss (%EWL) was more with BPD-DS than SIPS at 6, 9, 12, 18, and 24 months. Patient lost a mean body mass index (BMI) of 23.3 (follow-up: 69%) and 20.3 kg/m2 (follow-up: 71%) at 2 years from the BPD-DS and SIPS surgery, respectively. However, patients who had undergone SIPS procedure had significantly shorter operative time, shorter length of stay, fewer perioperative and postoperative complications than BPD-DS (P<.001). Interestingly, even though BPD-DS patients lost slightly more weight, the actual final BMI for SIPS group was lower than BPD-DS group (25.6 versus 26.9) (P<.05). There was no statistical difference between 2 groups for postoperative nutritional data such as vitamins D, B1, B12, serum calcium, fasting blood glucose, glycosylated hemoglobin (HbA1C), insulin, serum albumin, serum total protein, and lipid panel. CONCLUSION The SIPS is a simplified DS procedure. The SIPS eliminates one anastomosis and compared with BPD-DS has fewer perioperative and postoperative complications, shorter operative time and length of stay, and similar nutritional results at 2 years. However, weight loss was more with BPD-DS. A fair criticism is that the vast majority of BPD-DS cases were done before the SIPS cases. As a result, experience and learning curve cannot be completely dismissed when viewing postoperative complications.

Abstract
PURPOSE OF REVIEW Obesity is a worldwide epidemic, having profound effects on Western populations. Bariatric surgery has long been employed to treat obesity and its related comorbidities. Over time, researchers have amassed significant data to support bariatric surgery in the pursuit of treating diabetes mellitus. This review serves to introduce the most recent findings and their relation to the various bariatric surgical options as bariatric surgery will continue to cement itself in the treatment paradigm of diabetes mellitus. RECENT FINDINGS Numerous studies performed in the past 10 years have demonstrated the improvement or cessation of diabetes with bariatric surgical intervention. In comparing the vertical sleeve gastrectomy and Roux-en-Y gastric bypass, data demonstrate a more beneficial response of diabetes to the Roux-en-Y gastric bypass, and an even further exaggerated response with the biliopancreatic diversion/duodenal switch. The benefit has long been established, but what causes the improvement in diabetes mellitus after bariatric surgery? Recent data suggest a decrease in circulating bile salts as well as changes to inflammatory markers and circulating cytokines. Furthermore, tailoring of existing surgical procedures has led to the development of the SIPS procedure, and its benefit is demonstrated in bypassing a large portion of intestine while eliminating an enteroenterostomy, helping to reduce short gut syndrome and resultant diarrhea. SUMMARY The surgical climate within the bariatric field is changing and will continue to do so in the future. As the understanding of the causes or mechanisms in which bariatric surgery improves metabolic disorders becomes more evident, the process of individualizing care for specific patients will become more prevalent.

Abstract
Long-term weight loss after Roux-en-Y gastric bypass (RYGB) in super-obese patients has not been ideal. Biliopancreatic diversion with duodenal switch (DS) is argued to be better; however, additional side effects are feared. The aim of the present study was to determine differences in results after DS and RYGB in publications from single-centre comparisons. A systematic review of studies containing DS and RYGB performed at the same centre was performed. Outcome data were weight results, resolution of comorbid conditions, perioperative results and complications. Main outcome was difference in weight loss after DS and RYGB. Secondary outcomes were difference in resolution of comorbidities, perioperative results and complications. The final analysis included 16 studies with in total 874 DS and 1,149 RYGB operations. When comparing weight results at the longest follow-up of each study, DS yielded 6.2 (95% confidence interval 5.0-7.5) body mass index units additional weight loss compared with RYGB, P < 0.001. Operative time and length of stay were significantly longer after DS, as well as the risk for post-operative leaks, P < 0.05. DS is more effective than RYGB as a weight-reducing procedure. However, this comes at the price of more early complications and might also yield slightly higher perioperative mortality.

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
Background Both gastric bypass (GB) and duodenal switch with sleeve gastrectomy (DS) have been widely used as bariatric surgeries, and DS appears to be superior to GB. The aim of this study was to better understand the mechanisms leading to body weight loss by comparing these two procedures in experimental models of rats. Methods Animals were subjected to GB, DS or laparotomy (controls), and monitored by an open-circuit indirect calorimeter composed of comprehensive laboratory animal monitoring system and adiabatic bomb calorimeter. Results Body weight loss was greater after DS than GB. Food intake was reduced after DS but not GB. Energy expenditure was increased after either GB or DS. Fecal energy content was increased after DS but not GB. Conclusion GB induced body weight loss by increasing energy expenditure, whereas DS induced greater body weight loss by reducing food intake, increasing energy expenditure and causing malabsorption in rat models.

Abstract
For some time now, the research on gastric motility and function has fallen behind in the amount of research on gastric endocrine, exocrine secretion, and gastric morphology. In this paper, a noninvasive method to study gastric motility was developed, taking bioimpedance measurements over the gastric area simultaneously with the electrogastrography (EGG). This is based on the concept of observing and analyzing simultaneously the intrinsic electrical gastric activity (basic electric rhythm) and the mechanical gastric activity. Additionally, preliminary clinical studies of healthy subjects and subjects with functional dyspepsia (FD) and gastritis were carried out. The impedance gastric motility (IGM) measurements of the healthy and FD subjects were compared, along with the studies of the FD subjects before treatment and after one week and three weeks of treatment. We also compared IGM measurements of healthy subjects and subjects with erosive gastritis, along with the studies of the subjects with erosive gastritis before treatment and after one week of treatment. Results show that FD subjects have poor gastric motility (P<0.01). After a week of treatment, the gastric motility of FD subjects was not yet improved although the EGG had returned to normal by this time. By three weeks of treatment, the regular IGM rhythm returned in FD subjects. There was a significant difference of IGM parameters between the gastritis and healthy subjects (P<0.05). The EGG rhythm of the gastritis subjects returned to normal at one week post-treatment, while IGM parameters showed a trend to improvement (P>0.05), These results suggest the possibility of clinic application of the proposed method.

Abstract
CONTEXT: The surgical treatment for morbid obesity is becoming common in this country. Only a few papers reported the long-term results of the surgical approach for morbid obesity, mainly in terms of quality of life. OBJECTIVE: To compare mortality rate, weight loss, improvement of both diabetes and hypertension, and quality of life of patients from the public healthcare in Cuiabá, MT, Brazil, who underwent either medical or surgical interventions after a minimum of 2 years. METHODS: The population of this study was constituted by morbidly obese patients who initiated treatment between June 2002 and December 2006. The casuistic consisted of 89 patients submitted to medical therapy and 76 patients who underwent surgical procedures. The main variables were weight loss, improvement of hypertension and diabetes, quality of life, and mortality. RESULTS: The overall results showed that weight loss was significant in the two groups (P<0.001); however surgical patients showed a greater loss than the medical group (P = 0.05). The improvement of diabetes and hypertension was significantly greater in the surgical group (P<0.001), in which no cases of diabetes persisted. There was an increase in cases of hypertension among patients receiving medical attention. Mortality occurred in six cases (6.7%) of the medical group and in five cases (6.6%) of the surgical group (P = 0.97). The median grade of the quality of life score obtained by surgical patients (2.37 [range: -2.50 to 3.00]) was significantly greater (P<0.001) when compared to the medical group (1.25 [range: -1.50 to 3.00]). CONCLUSION: The surgical group presented better results regarding the weight loss, quality of life and improvement of hypertension and diabetes. There was no significant difference in mortality rate between the two groups after a minimum of 2 years.

Abstract
BACKGROUND Laparoscopic biliopancreatic diversion/duodenal switch (LDS) and laparoscopic Roux-en-Y gastric bypass (LRYGB) are the main surgical options for super-obese patients (body mass index >50 kg/m(2)). METHODS We performed a medium long-term evaluation of 13 super-obese patients who had undergone LDS compared with a control group of 19 patients who had undergone LRYGB. The patients were assessed 31 months (range 17-38) and 34 months (range 26-62) after LDS and LRYGB, respectively, for body mass index changes, relief of co-morbidities, nutrition, quality of life, postoperative bowel function, and accumulated healthcare consumption. RESULTS The mean body mass index decreased from 54.9 to 30.0 kg/m(2) in the LDS group and 57.8 to 39.8 kg/m(2) in the LRYGB group (P = .005). The hemoglobin A1c level was lower in the LDS group than in the LRYGB group (3.8 +/- .31% versus 4.3 +/- .43%, respectively; P = .01). The LDS patients reported greater energy intake than the LRYGB patients (3132 +/- 1392 kcal versus 2014 +/- 656 kcal, respectively; P = .021). The number of stools daily was 4.1 +/- 3.3 in the LDS group and 1.9 +/- 1.1 in the LRYGB group, P = .0482). Of the 12 patients in the LDS group, 6 reported fecal incontinence or soiling compared with 2 of 16 in the LRYGB group (P = .034). The number of outpatient visits was 5.6 +/- 4.6 for the LDS group and 2.0 +/- 1.9 for the LRYGB group (P = .016), and the number of telephone consultations was 5.0 +/- 5.6 and 1.4 +/- 1.6 for the LDS and LRYGB groups, respectively (P = .043). CONCLUSION LDS resulted in greater weight loss than LRYGB in super-obese patients. However, the LDS patients in our series had more frequent gastrointestinal side effects, required greater doses of calcium and vitamin supplementation, and required more postoperative monitoring. Patient satisfaction was high in both groups.

Abstract
BACKGROUND Laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic biliopancreatic diversion with duodenal switch (LDS) are surgical options for superobesity. A randomized trial was conducted to evaluate perioperative (30-day) safety and 1-year results. METHODS Sixty patients with a body mass index (BMI) of 50-60 kg/m(2) were randomized to LRYGB or LDS. BMI, percentage of excess BMI lost, complications and readmissions were compared between groups. RESULTS Patient characteristics were similar in the two groups. Mean operating time was 91 min for LRYGB and 206 min for LDS (P < 0.001). One LDS was converted to open surgery. Early complications occurred in four patients undergoing LRYGB and seven having LDS (P = 0.327), with no deaths. Median stay was 2 days after LRYGB and 4 days after LDS (P < 0.001). Four and nine patients respectively had late complications (P = 0.121). Mean BMI at 1 year decreased from 54.8 to 38.5 kg/m(2) after LRYGB and from 55.2 to 32.5 kg/m(2) after LDS; percentage of excess BMI lost was greater after LDS (74.8 versus 54.4 per cent; P < 0.001). CONCLUSION LRYGB and LDS can be performed with comparable perioperative safety in superobese patients. LDS provides greater weight loss in the first year.

Abstract
OBJECTIVE To assess vitamin D status and the influences of race, sun exposure and dietary vitamin D intake on vitamin D levels, and to evaluate two vitamin D repletion regimens in extremely obese patients awaiting bariatric surgery. METHODS A cross-sectional analysis of dietary vitamin D, sun exposure, PTH [intact (iPTH) and PTH(1-84)] and 25-hydroxyvitamin D (25OHD; differentiated 25OHD2 and 25OHD3) in 56 obese [body mass index (BMI) > 35 kg/m(2)] men and women (age 20-64 years). In a pilot clinical trial, 27 subjects with 25OHD levels < 62 nmol/l were randomized to receive ergocalciferol or cholecalciferol for 8 weeks. RESULTS Serum 25OHD was low (mean 45 +/- 22 nmol/l) and was inversely associated with BMI (r = -0.36, P < 0.01). Each BMI increase of 1 kg/m(2) was associated with a 1.3 nmol/l decrease in 25OHD (P < 0.01). BMI, sun exposure, African American race and PTH predicted 40% of the variance in 25OHD (P < 0.0001). Serum 25OHD significantly increased at 4 and 8 weeks in both treatment groups (P < 0.001), whereas PTH(1-84) declined significantly in subjects treated with cholecalciferol (P < 0.007) and tended to decrease following ergocalciferol (P < 0.09). CONCLUSIONS In severely obese individuals, those who are African American, have higher BMI and limited sunlight exposure are at greatest risk for vitamin D insufficiency. These demographic factors can help to identify at-risk patients who require vitamin D repletion prior to bariatric surgery. Commonly prescribed doses of ergocalciferol and cholecalciferol are effective in raising 25OHD. Further investigation is needed to evaluate whether these regimens have differential effects on PTH, and to determine the optimal regimen for vitamin D repletion in the extremely obese patient.

Abstract
BACKGROUND Bariatric surgery is widely performed to induce weight loss. OBJECTIVE The objective was to examine changes in vitamin status after 2 bariatric surgical techniques. DESIGN A randomized controlled trial was conducted in 2 Scandinavian hospitals. The subjects were 60 superobese patients [body mass index (BMI; in kg/m(2)): 50-60]. The surgical interventions were either laparoscopic Roux-en-Y gastric bypass or laparoscopic biliopancreatic diversion with duodenal switch. All patients received multivitamins, iron, calcium, and vitamin D supplements. Gastric bypass patients also received a vitamin B-12 substitute. The patients were examined before surgery and 6 wk, 6 mo, and 1 y after surgery. RESULTS Of 60 surgically treated patients, 59 completed the follow-up. After surgery, duodenal switch patients had lower mean vitamin A and 25-hydroxyvitamin D concentrations and a steeper decline in thiamine concentrations than did the gastric bypass patients. Other vitamins (riboflavin, vitamin B-6, vitamin C, and vitamin E adjusted for serum lipids) did not change differently in the surgical groups, and concentrations were either stable or increased. Furthermore, duodenal switch patients had lower hemoglobin and total cholesterol concentrations and a lower BMI (mean reduction: 41% compared with 30%) than did gastric bypass patients 1 y after surgery. Additional dietary supplement use was more frequent among duodenal switch patients (55%) than among gastric bypass patients (26%). CONCLUSIONS Compared with gastric bypass, duodenal switch may be associated with a greater risk of vitamin A and D deficiencies in the first year after surgery and of thiamine deficiency in the initial months after surgery. Patients who undergo these 2 surgical interventions may require different monitoring and supplementation regimens in the first year after surgery. This trial was registered at ClinicalTrials.gov as NCT00327912.

Abstract
To update evidence-based best practice guidelines for surgical care in weight loss surgery (WLS). Systematic search of English-language literature on WLS in MEDLINE, EMBASE, and the Cochrane Library between April 2004 and May 2007. Use of key words to narrow the search for a selective review of abstracts, retrieval of full articles, and grading of evidence according to systems used in established evidence-based models. Evidence-based best practice recommendations from the most recent literature on surgical methods and technologies, risks and benefits, outcomes, and surgeon qualifications and credentialing. We identified >135 articles; the 65 most relevant were reviewed in detail. Regular updates of evidence-based recommendations for best practices in WLS are required to address rapid changes in surgical techniques and patient demographics. Key factors in patient safety include surgical risk factors, type of procedure, surgeon training, and facility certification.

Abstract
BACKGROUND A paucity of information is available on the comparative body composition changes after bariatric procedures. The present study reports on the body mass index (BMI) and body composition changes after 4 procedures by a single group. METHODS At the initial consultation, the weight and body composition of the patients undergoing 4 different bariatric procedures were measured by bioimpedance (Tanita 310). Follow-up examinations were performed at 1 year and at subsequent visits after surgery. Analysis of variance was used to compare the postprocedure BMI and body composition. Analysis of covariance was used to adjust for baseline differences. RESULTS A total of 101 gastric bypass (GB) patients were evaluated at 19.1 + or - 10.6 months, 49 biliopancreatic diversion with the duodenal switch (BPD/DS) patients at 27.5 + or - 16.3 months, 41 adjustable gastric band (AGB) patients at 21.4 + or - 9.2 months, and 30 sleeve gastrectomy (SG) patients at 16.7 + or - 5.6 months (P <.0001). No differences were found in patient age or gender among the 4 groups. The mean preoperative BMI was significantly different among the 4 groups (P <.0001): 61.4 kg/m(2), 53.2, 46.7, and 44.3 kg/m(2) for the SG, BPD/DS, GB, and AGB group, respectively. The postoperative BMI adjusted for baseline differences was 27.8 (difference 23.6 + or - 8.3), 32.5 (difference 15.6 + or - 5.0), 37.2 (difference 18.2 + or - 8.2), and 39.5 kg/m(2) (difference 7.5 + or - 4.3) for the BPD/DS, GB, SG, and AGB groups, respectively (P <.0001). The percentage of excess weight loss was 84%, 70%, 49%, and 38% for the BPD/DS, GB, SG, and AGB groups, respectively (P <.0001). The postoperative percentage of body fat adjusted for baseline differences was 25.7% (23.9% + or - 7.0%) 32.7% (16.1% + or - 10.5%) 37.7% (16.7% + or - 5.6%), and 42% (6.0% + or - 6.8%) for the BPD/DS, GB, SG, and AGB groups, respectively (P <.0001). The lean body mass changes were reciprocal. CONCLUSION Although the BPD/DS procedure reduced the BMI the most effectively and promoted fat loss, all the procedures produced weight loss. The AGB procedure resulted in less body fat loss within 21.5 months than SG within 16.7 months. Longer term observation is indicated.

Abstract
Severe thiamine (vitamin B-1) deficiency is a medical emergency that has long been recognized as a potential complication of bariatric surgery. The incidence of this rare complication is largely unknown. We describe a super-obese male patient with extreme lower limb weakness 3 months following a duodenal switch operation, occurring in association with persisting vomiting. Excessive malabsorption led to severe malnutrition, with lower limb edemas and clinical evidence of ascites and pleural effusion. Blood tests revealed low levels of albumin, hemoglobin, potassium, vitamins A, B-1, and B-6, and elevated prothrombin time. The symptoms of neuropathy improved after extensive nutritional therapy. Weight eventually stabilized following elongation of the common channel. This case report demonstrates the importance of awareness of neurological complications following bariatric surgery. These complications require urgent and vigorous therapy when they occur.

Abstract
Adolescents bariatric surgery (ABS) in morbid obesity (MO), with or without comorbid conditions, is and will be more and more indicated. Restrictive operations have the advantage of no influence on absorption. Laparoscopic sleeve gastrectomy (LSG) can be an excellent alternative. A LSG was done in a 10-year-old boy, body mass index (BMI) 42, who has Blount's disease (tibia vara) with severe pain at the knee joints that made him a wheelchair-bound person. He had a LSG and gallbladder removal without incidents. Eight months later, he has a BMI 28 and almost all his knees pain is gone. No side effects have been detected. A LSG may be the ideal bariatric operation for ABS with MO.

Surg Obes Relat Dis 2008; 3:521-5.

Abstract
BACKGROUND Of patients who have undergone gastric banding, 11-25% will require a major reoperation with band removal and conversion to another bariatric procedure after they have failed to lose sufficient weight or have developed dysphagia or reflux. The aim of this study was to evaluate the respective benefits of Roux-en-Y gastric band (RYGB) or biliopancreatic diversion with duodenal switch (BPD-DS) after failed gastric banding and whether 1 of the 2 procedures might be a better procedure for such cases. METHODS RYGB or BPD-DS was performed according to the institutional protocols with synchronous band removal, irrespective of the reason for failure. RESULTS Of the 53 patients, 32 underwent laparoscopic RYGB for a body mass index (BMI) of 43.1 +/- 6.4 kg/m(2) (BMI 45.8 +/- 6.4 kg/m(2) before laparoscopic adjustable gastric banding) and 21 underwent BPD-DS for a BMI of 46.0 +/- 5.5 kg/m(2) (BMI 49.6 +/- 5.2 kg/m(2) before laparoscopic adjustable gastric banding). BPD-DS required significantly longer operative times (239.7 +/- 55.8 versus 135 +/- 26.7 minutes) and resulted in more complications (62% versus 12.5%; P <.002). No patients died postoperatively. The 2 groups of patients had a similar BMI at 12 and 18 months after revision (BMI 33.4 +/- 5.6 kg/m(2) and 31.4 +/- 3.5 kg/m(2)). The weight loss was greater after BPD-DS than after RYGB compared with the prerevision weight loss (66.2% versus 58.8% excess weight loss) or initial weight (73% versus 61.8%), although this was not significant. CONCLUSION Despite an excessive rate of complications that were, in part, related to the learning curve in this series, BPD-DS resulted in greater weight loss compared with RYGB. However, both procedures were successful after failed gastric banding. A more accurate definition of failure could help to determine the respective indications for revisional surgery.
