BACKGROUND Important endpoints of bariatric surgery are weight loss and improvement of comorbidities, of which obstructive sleep apnea (OSA) is the highest accompanying comorbidity (70%). This study aimed to evaluate the influence of OSA on weight loss after bariatric surgery and to provide predictive factors for insufficient weight loss (defined as ≤50%(More)
BACKGROUND To evaluate the influence of obstructive sleep apnea (OSA) on postoperative cardiopulmonary complications in bariatric surgery patients. METHODS PubMed, Embase, and the Cochrane central register databases were searched. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement was used for reviewing. RESULTS Thirteen(More)
BACKGROUND There is an overall complication rate of 6.3%-10% after bariatric surgery. After ruling out anatomic/physical causes, there is a substantial group of patients who develop unexplained postsurgical abdominal pain. OBJECTIVES To inventory the prevalence of unexplained abdominal pain after laparoscopic Roux-en-Y gastric bypass or laparoscopic(More)
BACKGROUND The Obesity Surgery Mortality Risk Score (OS-MRS) is a validated instrument for mortality risk prediction in patients undergoing laparoscopic Roux-en-Y gastric bypass (LRYGB) procedures classifying patients into low risk (class A), intermediate risk (class B), and high risk (class C). OBJECTIVES The primary aim of this study was to evaluate the(More)
BACKGROUND To examine the influence of obstructive sleep apnea (OSA) on the quality of life (QoL) in bariatric surgery. METHODS All patients who underwent a laparoscopic Roux-and-Y gastric bypass (LRYGB), preoperative poly(somno)graphy and completed an Impact of Weight on QoL-Lite questionnaire before and after surgery were included. RESULTS A total of(More)
BACKGROUND The aim of this study was to evaluate the value of preoperative liver function tests (LFTs) in patients with uncomplicated gallstone disease and scheduled for laparoscopic cholecystectomy. METHODS All 1112 patients who underwent a laparoscopic cholecystectomy for symptomatic gallstone disease during a 6-year cohort were retrospectively(More)
BACKGROUND Around 10 % of the bariatric surgery patients experience postoperative complications (<30 days). It could be hypothesized that complications influence postoperative weight loss, which is one of the most important endpoints of bariatric surgery. Therefore, this study inventoried the effect of complications on postoperative weight loss. METHODS A(More)
Women desiring pregnancy might fail to conceive due to their obesity. Bariatric surgery has shown to reduce this infertility up to 58% and is therefore considered a successful strategy for morbidly obese infertile women. Nevertheless, when pregnancy has succeeded, surgery-related complications might occur.Banded laparoscopic Roux-en-Y gastric bypass(More)
BACKGROUND Laparoscopic bariatric surgery is increasingly being performed worldwide. It is estimated that trocar port hernias occur more often in obese patients due to their obesity and because the ports are not closed routinely. The aim of the present study was to analyze the incidence, risk factors, and management of patients with trocar port hernias(More)
