Perforated duodenal ulcer following RYGB is an unusual clinical situation that may be a diagnostic challenge. Only 23 cases have previously been reported. We present five cases. The hallmark of visceral perforation, namely pneumoperitoneum, was not seen in three of the four cases that underwent cross sectional imaging. This is perhaps due to the altered anatomy of the RYGB that excludes air from the duodenum. Our cases had more free fluid than expected. The bariatric surgeon should not wait for free intraperitoneal air to suspect duodenal perforation after RYGB...

BACKGROUND: Little is known regarding the use of opioid analgesics among patients who have undergone bariatric surgery. The Roux-en-Y gastric bypass (RYGB) procedure has been shown to significantly increase the rate of absorption of and exposure to morphine, raising concerns regarding the potentially increased risk of side-effects and the development of substance-use disorder. OBJECTIVES: The aim of this study was to describe the pattern of opioid use over time following RYGB and to see if the pattern differs between patients with a high opioid consumption (HOC) prior to surgery and those with a low consumption (LOC)...

The One Anastomosis (Mini) Gastric Bypass is rapidly gaining acceptance. This review reports cumulative results of 12,807 procedures in obese patients with a mean age of 41.18 years and BMI of 46.6 kg/m2 . The overall mortality was 0.10% and the leak rate was 0.96%. The follow-up duration ranged from 6 months to 12 years. A marginal ulceration rate of 2.7% and an anaemia rate of 7.0% were reported. Approximately 2.0% of patients reported postoperative gastro-oesophageal reflux and 0.71% developed malnutrition...

BACKGROUND: Situs inversus is a congenital condition in which the major visceral organs are reversed or mirrored from their normal positions. Situs inversus is found in about 0.01% of the population. In the most common situation, situs inversus totalis involves complete transposition (right to left reversal) of all of the abdominal organs. Several successful and safe laparoscopic weight loss surgeries were previously reported in morbidly obese patients with situs inversus (Aziret et al...

BACKGROUND: Sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) are both effective bariatric procedures to treat type 2 diabetes (T2DM) and obesity. The contribution of changes in bile acids (BAs) and fibroblast growth factor19 (FGF19) to such metabolic improvements is unclear. METHODS: We examined associations between changes in BAs, FGF19 (fasting and prandial), with changes in body weight, glycemia, and other metabolic variables in 61 obese patients with T2DM before and 1 year after randomization to SG or RYGB...

BACKGROUND: The prevalence of psychological disorders in bariatric surgery candidates is well established, where anxiety and depression are commonly observed. Depression prevalence and evolution after gastric bypass, and its impact on weight loss, have been less explored, especially among low-income patients. METHODS: A retrospective study with low-income patients undergoing bariatric surgery from 2015 to 2016. A comparative analysis of preoperative depression (the Beck Depression Inventory II) was performed and compared at 6 and 12 months...

INTRODUCTION/PURPOSE: Adverse childhood experiences (ACEs) are known risk factors for obesity and poor outcomes following weight loss interventions. ACEs are also associated with addictive behaviors and, potentially, food addiction (FA). This study examined the relationship between ACEs and FA, and their association to undergoing bariatric surgery and post-surgical weight loss outcomes. MATERIALS AND METHODS: Between June 2013 and January 2016, 1586 bariatric-surgery-seeking patients completed a psychological evaluation...

PURPOSE: The objective of this descriptive study was to identify clinical characteristics of Roux-en-Y gastric bypass (RYGB) patients who died from intentional self-harm or accidental overdose postoperatively. MATERIALS AND METHODS: This retrospective, descriptive study included RYGB patients from a large rural medical center that completed surgery between January 2004 and December 2014 and died from intentional self-harm or accidental overdose through December 2015...

BACKGROUND: Despite the ultrasound guidance of transversus abdominis plane (TAP) blocks has allowed greater precision of needle placement in the desired tissue plane, visualization of the abdominal wall muscles can be hindered by morbid obesity and could lead to failed regional anesthesia. The aim of this study was to assess the feasibility and effect of laparoscopic-guided TAP block in patients undergoing Roux-en-Y gastric bypass and to compare it with port-site infiltration. PATIENTS AND METHODS: A prospective randomized clinical trial was performed...

INTRODUCTION: Bariatric surgery is a well-established treatment option for serious obesity and concomitant type 2 diabetes mellitus (T2DM). In this analysis, we investigated predictors for bariatric surgery in everyday clinical practice. MATERIALS AND METHODS: In the DPV-registry, patients with T2DM from Germany and Austria treated by bariatric surgery were compared to non-surgery controls by descriptive statistics and regression analysis. RESULTS: Among 277,862 patients with T2DM, 0...

PURPOSE: The number of laparoscopic adjustable gastric banding (LAGB) removal has increased throughout the years. The aim of the study was to evaluate the outcomes in patients undergoing LAGB removal with or without further bariatric surgery. MATERIALS AND METHODS: Data prospectively collected from consecutive patients undergoing LAGB removal from 2008 to 2016 at our institution were retrospectively analyzed. Obesity-related comorbidities, complications, and body mass index (BMI) before removal and at 1-year follow-up were evaluated...

BACKGROUND: There is currently no evidence to support the routine use of an abdominal drain following laparoscopic Roux-en-Y gastric bypass (RYGB). Our aim was to investigate drain use in laparoscopic RYGB and its effects on postoperative pain. METHODS: Sixty-six patients were randomly divided into two groups as no-drain (n = 36) and with-drain (n = 30). Intraoperative (time, blood loss, complications) and postoperative outcomes (morbidities, pain scores, hospital stay) were compared...

BACKGROUND: Little is known about changes in bone mineral density (BMD) following weight loss after one-anastomosis gastric bypass (OAGB) and the role of serum vitamin D and its supplementation on bone metabolism. We evaluated BMD after OAGB as a function of vitamin D supplementation with respect to a minimum threshold of 25-hydroxy-vitamin-D [25(OH)D] concentration, which could prevent or decelerate an eventual bone loss. METHODS: Fifty bariatric patients who participated in the randomized controlled trial were included in this analysis...

BACKGROUND: There seems to exist a belief that weight loss is proportionally associated with improvement of health-related quality of life (HRQoL) after bariatric surgery. HRQoL is a complex multidimensional construct of one's perception of health and well-being and is measured through generic and disease specific questionnaires. OBJECTIVES: This study aimed to test the associations between weight loss after bariatric surgery and both generic and obesity-specific HRQoL, and mental distress, controlling for other patient characteristics...

AIM: Laparoscopic gastric plication (LGP) is a bariatric surgical technique based on the anatomical principles of laparoscopic sleeve gastrectomy (LSG), but its effects on the metabolic profile are still uncertain. The aim of our study is to compare the changes in weight, metabolic parameters and gastric histology following intervention by gastric plication (GP) and sleeve gastrectomy (SG) in an experimental model of obesity. METHODS: To conduct the study, 32 8-week-old male Sprague-Dawley rats (Charles River®) were fattened by means of a cafeteria diet and randomly assigned to the following experimental groups: group 1: GP (n = 12); group 2: SG (n = 12) and group 3: sham (n = 8)...
