Background: Internal hernias (IHs) can complicate laparoscopic Roux-en-Y gastric bypass (LRYGB). A number of radiological investigations can be used in the diagnosis. These include plain X-rays, upper gastrointestinal (UGI) series, ultrasound, and computed tomography (CT) scanning.

Our aim was to observe the changes in blood pressure (BP) in a cohort of 100 patients followed prospectively for 1 year after LRYGB.
Methods: BP measurements were recorded prospectively in 100 consecutive patients preoperatively and then postoperatively at weeks 1, 5, 9, and months 6 and 12.
Background: A discrepancy exists between patient perceptions of post-bariatric surgery reconstruction and cost, value, and ultimate attainability. The authors investigated prospective gastric bypass patients to identify misconceptions and strategies to aid in the attainability of post-bariatric surgery reconstruction.
Methods: One hundred seventy-six prospective gastric bypass patients were surveyed for perceptions of plastic surgery, a "club" concept integrating plastic surgical/bariatric teams, and payment strategies.
Background: Partial small bowel obstruction can occur as a result of circumferential extrinsic compression of the Roux limb as it traverses the transverse mesocolic rent from thickened cicatrix formation in this area. The aim of this study is to examine the incidence of Roux limb compression with particular attention to the timing of presentation and associated weight loss in the setting of a university hospital in the United States.
Methods: A retrospective chart review was performed of all patients undergoing laparoscopic Roux-en-Y gastric bypass who developed symptomatic small bowel obstruction requiring operative intervention from January 1, 2000 and September 15, 2006.
Background: Internal hernias (IHs) can occur after laparoscopic Roux-en-Y gastric bypass (LRYGBP), perhaps because of a lack of adhesion formation at the cut edges of the mesentery and a cutting through of sutures with a decrease in fat from weight loss. In patients undergoing reoperation after LRYGBP, we observed that bioabsorbable glycolide copolymer staple-line reinforcement (SLR) placed to mitigate staple-line bleeding had evoked adhesiogenesis and tissue fusion at the mesentery edges; therefore, we investigated whether use of this material decreases post-LRYGBP IH rates.
Methods: The records of the 43 patients (3%) in whom an IH developed during a mean follow-up time of 2 years in a series of 1,704 LRYGBP procedures were reviewed retrospectively.
Investigation of the bypassed stomach in patients with suspected peptic ulcer disease presents a major challenge to bariatric surgeons. Various methods have been suggested for visualization of the duodenum and bypassed stomach. These include endoscopy via percutaneous gastrostomy access, retrograde endoscopy and virtual gastroscopy using CT scan.

The aim of this study was to see when internal hernias occur in relation to weight loss and time course after surgery. Furthermore, we wish to examine the impact of Roux limb positioning ante- versus retrocolic and whether switching to running versus interrupted closure of the mesenteric defects created at surgery made any difference.

This study was primarily conducted to examine whether there is any difference in the length of hospital stay and duration of operation in patients who undergo concomitant cholecystectomy with their LRYGBP. In addition, the frequency and nature of complications in the two groups were compared.
