BACKGROUND The exclusion of the proximal small intestine is thought to play a major role in the rapid improvement in the metabolic control of diabetes after gastric bypass. OBJECTIVE In this randomized, prospective, parallel group study, we sought to evaluate and compare the effects of laparoscopic Roux-en-Y gastric bypass (LRYGB) with those of(More)
BACKGROUND The mechanisms of amelioration of glycemic control early after laparoscopic Roux-en-Y gastric bypass (LRYGB) or laparoscopic sleeve gastrectomy (LSG) are not fully understood. METHODS In this prospective, randomized 1-year trial, outcomes of LRYGB and LSG patients were compared, focusing on possibly responsible mechanisms. Twelve patients were(More)
OBJECTIVE Laparoscopic sleeve gastrectomy (LSG) has been proposed as an effective alternative to the current standard procedure, laparoscopic Roux-en-Y gastric bypass (LRYGB). Prospective data comparing both procedures are rare. Therefore, we performed a randomized clinical trial assessing the effectiveness and safety of these 2 operative techniques. (More)
BACKGROUND Deficiencies in micronutrients after bariatric operations are frequent, despite routine supplementation. Main outcome measures were pre- and postoperative frequency of nutrient deficiencies and success rate of their treatment. METHODS Between 5/2004 and 12/2006, 136 patients (m:f = 0:4) with an average body mass index of 45 (35-58) kg/m(2) and(More)
BACKGROUND Laparoscopic sleeve gastrectomy (LSG) is gaining popularity, but studies reporting long-term results are still rare. The objective of this study was to present the 5-year outcome concerning weight loss, modification of co-morbidities, and late complications. METHODS This is a retrospective analysis of a prospective cohort with a minimal(More)
OBJECTIVE Increased delivery of bile acid salts (BA) to distal L-cells and altered TGR5 receptor activation may contribute to the early and substantial increases in gut peptide secretion seen after bariatric surgery. To further elucidate a potential role of BA in the secretion of GLP-1 and PYY, we analyzed plasma BA concentrations in 14 morbidly obese(More)
We describe a young female patient suffering from a PEComa (perivascular epithelioid cell tumor) of the cecum, incidentally found at an examination made by her family physician. The perivascular epithelioid cell tumor is a very rare tumor, until today reported in a few cases in falciform ligament, uterus, jejunum, terminal ileum, rectum, liver, kidney,(More)
OBJECTIVE The melanocortin system is a key regulator in the hypothalamus of energy intake and expenditure. It is frequently linked with obesity and apparently modulates sympathetic outflow to white adipose tissues. The role of the melanocortins within adipose tissues, however, is not entirely clear. This study was aimed at determining the quantitative(More)
OBJECTIVE To assess whether antibiotic prophylaxis at urinary catheter removal reduces the rate of urinary tract infections. SUMMARY OF BACKGROUND DATA Urinary tract infections are among the most common nosocomial infections. Antibiotic prophylaxis at urinary catheter removal is used as a measure to prevent them, albeit without supporting evidence. (More)
