INTRODUCTION: Roux-en-Y gastric bypass is the most common bariatric procedure in Belgium. Retrograde intussusception is identified as a rare late complication. METHODS: Here we present two cases of retrograde jejuno-jejunal intussusception after Roux-en-Y gastric bypass. RESULTS: Women who experienced excellent weight loss appear most prone. Although ectopic pacemaking is suggested, the exact pathophysiologic mechanism remains unclear. Simple manual reduction seems to be insufficient as treatment...

BACKGROUND: Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG) can be proposed in case of failed laparoscopic adjustable gastric band (LAGB). The main question is whether the revisional procedure is carried out in one or two stages. OBJECTIVE: Postoperative outcomes between the one-step approach and the two-step approach of conversion of failed LAGB to RYGB or SG were, respectively, compared. METHODS: A systematic review of the literature published until June 2019 was conducted...

BACKGROUND: Obesity is well known to increase the risk of gastroesophageal reflux disease (GERD). The impact of sleeve gastrectomy (SG) on GERD is still discussed but seems to be associated with the development of de novo GERD or the exacerbation of preexisting GERD. OBJECTIVE: The objective of this study was to evaluate the impact of preoperative pH monitoring, using the DeMeester score (DMS), on the risk of conversion to Roux-en-Y gastric bypass (RYGB) after SG...

INTRODUCTION: In the last two decades, an impressive increase in the number of surgical interventions was recorded in bariatric surgery. Similarly, several bibliometric studies reported an increasing trend for scientific production. This study aims to compare these two trends. METHODS: This study focused on the period 2003-2016 and included the following procedures: adjustable gastric banding (AGB), bilio-pancreatic deviation (BPD), one-anastomosis gastric bypass (OAGB), Roux-en-Y gastric bypass (RYGB), sleeve gastrectomy (SG), and vertical banded gastroplasty (VBG)...

BACKGROUND: Insufficient weight loss or secondary weight regain with or without recurrence of comorbidity can occur years after laparoscopic Roux en Y gastric bypass (LRYGB). In selected patients, increasing restriction or adding malabsorption may be a surgical option after conservative measures failed. OBJECTIVES: Evaluation of short and long term results of revisional surgery for insufficient weight loss or weight regain after LRYGB. SETTING: Tertiary hospital...

PURPOSE: Distinct anatomical rearrangements of the gastrointestinal tract achieved by various types of bariatric surgery cause changes in nutrient intake and gut microbiota. The contribution of such gut microbiota changes to remission of type 2 diabetes (T2D) remains unclear. AIM: We examined gut microbiota changes following banded Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG) in a randomised study, in relation to T2D remission. MATERIALS AND METHODS: Whole-metagenome shotgun sequencing was carried out on paired stool samples at pre- and 1-year post-surgery collected from 44 participants with T2D randomised to banded Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG)...

Published estimates of weight regain (WR) after bariatric surgery vary greatly. Understanding the sources of variability in the literature and clarifying the magnitude of WR after Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) are critical for informing expectations and planning interventions. A literature search through January 2019 yielded 15 English-language studies that reported WR in at least 30 participants, not selected based on weight loss or WR, at least 3 years after primary RYGB (n = 11) or SG (n = 5)...

OBJECTIVE: Weight regain (WR) after Roux-en-Y gastric bypass surgery (RYGB) starts to occur 2 years after surgery, ultimately affecting at least 25% of patients. A limited number of studies have evaluated the impact of antiobesity medications (AOMs) on this phenomenon. METHODS: This study reviewed the electronic medical records of 1,196 patients who underwent RYGB between 2004 and 2015. WR was evaluated by comparing each patient's weight during subsequent postoperative office visits to nadir weight (lowest weight after RYGB, n = 760), taking into consideration the interval during which WR occurred...

PURPOSE: Bariatric procedures reduce the capacity of the gut and alter the gastrointestinal transit time predisposing to micro-nutritional deficiencies. This study analyzed and compared the micro-nutritional parameters following laparoscopic sleeve gastrectomy (LSG) and Roux-en-Y gastric bypass (RYGB) in the Indian population. MATERIALS AND METHODS: This is a retrospective study of patients who underwent LSG or RYGB for morbid obesity at a tertiary care center between January 2015 and December 2016...

Background: Roux-en-Y gastric bypass (RYGB) has been proved to be more effective than other bariatric procedures in the long term on body-weight loss and remission of diabetes. However, the mechanism remains poorly understood. Long-term changes in energy metabolism after RYGB have rarely been reported. Objective: To investigate the long-term effects of RYGB on energy metabolism on a diet-induced obesity (DIO) mouse model. Methods: DIO mice fed a high-fat diet were assigned to two groups: RYGB (n=8) and sham (n=7), followed by high-fat diet feeding until 12 weeks after surgery...

İNTRODUCTION: Gastroesophageal reflux disease (GERD), which can be seen in up to 30% in postoperative series, is perhaps the most important complication of sleeve gastrectomy(SG). The general trend for patients who are planning to have bariatric surgery and have symptomatic GERD, Roux-en-Y gastric bypass is the most common choice. CASE PRESENTATION AND MANAGEMENT: A 42-year-old female patient with a body mass index of 36 kg/m2 presented to our clinic with obesity and symptomatic GERD. She had been using proton pump inhibitör (PPI) regularly for 1 year...
