Abstract
Bariatric surgery has been recognized as the most effective long-term treatment for morbid obesity. Despite the considerable positive results, adverse consequence can develop. Excessive Weight Loss (EXWL), a rare consequence of bariatric surgery, can lead to a broad adverse consequence. The aim of this study was determining of prevalence and the predicting model of EXWL in patient underwent bariatric surgery until 24 months after surgery. Data have been extracted from the National Obesity Surgery Database in obesity clinic of Iran University of Medical Sciences. The subjects of this retrospective cohort study were morbid obese individuals who underwent three various types of bariatric surgery [One Anastomosis Gastric Bypass (OAGB), Roux-en-Y Gastric Bypass (RYGB), or Sleeve Gastrectomy (SG)] in period of 24 months ago. EXWL has been defined as reaching to less than or equal to BMI 18.5 at any time until 24 months after surgery. SPSS was used in data analysis. Among 4214 subjects of this study, most excess weight loss after surgery has taken place in 18 months after surgery. 11.4% (n = 495) of patients experienced EXWL with highest percentage among OAGB patients (15.1%) at time of 24 months after surgery. The females (20.4% vs.9.9%) and younger persons (35.45 ± 10.25 vs. 39.06 ± 10.76) were more susceptible to EXWL. Patients with EXWL had significantly lower BMI (body mass index) (41.11 ± 4.51 vs. 46.73 ± 6.26) (Kg/m2), and were less probable to had emotional eating. Visceral fat level, fat percentage, and BMI were the best predictor of EXWL (P value for all < 0.05). So that per level increase in visceral fat, decreases the probability of EXWL as 47% and 61% in SG and OAGB. Moreover, each unit lower BMI leads to 25% higher susceptibility to experience EXWL. Surgery should be adjusted in younger females with a lower BMI and healthy metabolic status who are more prone to EXWL. In such a way that minimize weight loss speed/value. It may be possible by selection of other surgery procedures, rather than OAGB, tighter follow-ups, and consultations of patients after surgery is emphasized for more EXWL vulnerable patients.

Abstract
BACKGROUND Roux-en-Y gastric bypass (RYGB) is considered the gold standard for surgical management of morbid obesity due to its good results on weight loss and correction of comorbidities related to obesity. However, RYGB could have some adverse effect in the mid and long term. Here, we describe simple technique for laparoscopic reversal of RYGB into normal anatomy. METHODS The video shows our laparoscopic technique of the reversal of RYGB that was performed for severe protein deficiency. A 35-year-old woman with history of RYGB was referred to our center for restoration of normal digestive anatomy. RESULTS A 35-year-old woman was managed for severe protein deficiency 3 years after RYGB. Renutrition was performed using peripherally inserted central catheter but nutritional status was dependent on PICC. No gastrostomy tube was implemented at the time where the patient was referred because the reversal of RYGB was decided. We found a modified RYGB with a common channel of 130 cm, an alimentary channel of 350 cm, and a biliopancreatic limb of 70 cm. Revision to normal digestive anatomy was performed using linear staplers, resection of 15 cm of the small bowel, and only one small bowel anastomosis. An uneventful post-operative course enabled rapid discharge (post-operative day 5). At 6-month follow-up, there was no more protein deficiency and the patient had acceptable weight regain. CONCLUSION Reversal of RYGB is not usual and can be performed safely with few small bowel sacrifices. The optimization of pre-operative nutritional status is necessary to avoid complications.

Abstract
INTRODUCTION bariatric surgery is currently the only treatment that leads to long-term and sustained weight loss and decreased morbidity and mortality in morbidly obese individuals. Roux-en-Y bypass causes weight loss by restricting food intake associated with reduced intestinal absorption, in addition to multiple endocrine and satiogenic effects. Biliopancreatic diversion promotes weight loss mainly due to poor absorption of the nutrients ingested. Both procedures exclude parts of the gastrointestinal tract. OBJECTIVE to describe four cases of revisional surgery after primary bariatric surgery, due to serious nutritional complications, and to review the literature regarding this subject. METHODS a retrospective analysis of patients of Unicamps bariatric center database and review of the literatures were performed. RESULTS four patients were identified, 2 women and 2 men, with a mean age of 48 years. The mean body mass index before revisional surgery was 23.7 kg/m2. Three patients underwent Scopinaro biliopancreatic diversion, and onde patient underwent Roux-en-Y gastric bypass. The revisional surgeries were revision, conversion, and reversion. One patient died. For the review of the literature 12 articles remained (11 case reports and 1 case series). Another five important original articles were included. CONCLUSION fortunately, revision surgery is rarely necessary, but when indicated it has increased morbidity, It can be revision, reverion or conversion according to the severity of the patient and the primary surgery performed.

Abstract
Bariatric/metabolic surgery is currently the only effective long-term treatment for morbid obesity- and obesity-related diseases such as diabetes, heart disease, hypertension, obstructive sleep apnea, and dyslipidemia. In addition, bariatric/metabolic surgery has been shown to significantly reduce the incidence of diabetes and cancer and prolong life when compared to non-surgical therapies. However, as obesity is a chronic disease, recidivism of weight and comorbid conditions can occur. In addition, the surgical construct can lead to long-term consequences such as marginal ulceration, bowel obstruction, reflux, and nutritional deficiencies. Despite these drawbacks, prospective randomized controlled studies and long-term longitudinal population-based comparative studies greatly favor surgical intervention as opposed to traditional lifestyle, diet, and exercise programs. Revisional surgery can be quite complex and technically challenging and may offer the patient a wide variety of solutions for treatment of weight recidivism and complications after primary operations. Given the paucity of high quality published data, we have endeavored to provide indications for revisions after bariatric surgery.

Abstract
Revisional bariatric procedures are increasingly common. With more primary procedures being performed to manage severe obesity and its complications, 5% to 8% of these procedures will fail, requiring revisional operation. Reasons for revisional bariatric surgery are either primary inadequate weight loss, defined as less than 25% excess body weight loss, or weight recidivism, defined as a gain of more than 10 kg based on the nadir weight; however, each procedure also has inherit specific complications that can also be indications for revision. This article reviews the history of each primary bariatric procedure, indications for revision, surgical options, and subsequent outcomes.

Abstract
BACKGROUND Due to the large number of Roux-en-Y gastric bypass surgeries performed over the last decade, reversal of the bypass to normal anatomy has been increasingly reported. SETTING University affiliated Teaching Hospital, United States. OBJECTIVES The aim of this systematic review was to summarize the literature data regarding the indications, technical considerations, and outcomes of gastric bypass reversal. METHODS PubMed/MEDLINE search was conducted for articles reporting reversal of gastric bypass to normal anatomy. Patients' demographic characteristics, primary reason for reversal, reversal technique, and postreversal events were retrieved and categorized from each eligible paper. RESULTS Thirty-five articles encompassing a total of 100 patients were eligible. Malnutrition was the most common indication for reversal (12.3%), followed by severe dumping syndrome (9.4%), postprandial hypoglycemia (8.5%), and excessive weight loss (8.5%). Techniques for gastrogastrostomy were available in 42 patients, with the hand-sewn technique as the most common (67.4%) followed by the linear stapler (23.2%) and the end-to-end anastomosis stapler used in 3 patients (6.9%). The reversal technique was performed endoscopically and described in 3 studies (3 patients). Techniques for handling the Roux limb were described in 56 patients (56%); the limb was reconnected in 32 patients (57.2%) and resected in 24 patients (42.8%). Weight regain was the most prevalent postreversal event (28.8%), followed by severe gastroesophageal reflux diseases (10.2%) and persistent abdominal pain (6.8%). There was no reported mortality. CONCLUSION Gastric bypass reversal is indicated for excessive weight loss, dumping syndrome, and postprandial hypoglycemia. The procedure is well tolerated and feasible when performed laparoscopically and has no reported mortality.
