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 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)
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)
OBJECTIVE To analyze the feasibility, safety, complication and death rates, and early functional results of the transverse coloplasty pouch procedure after low anterior rectal resection and total mesorectal excision. SUMMARY BACKGROUND DATA The authors previously developed a novel neorectal reservoir, the transverse coloplasty pouch, in an animal model;(More)
PURPOSE Stapled hemorrhoidopexy has been demonstrated to be advantageous in the short term compared with the traditional techniques. We aimed to evaluate long-term results after stapled hemorrhoidopexy and to assess patient satisfaction in association with postoperative hemorrhoidal symptoms. METHODS This prospective study included 216 patients with Grade(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)
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)
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)
BACKGROUND We investigated early and midterm results of laparoscopic sleeve gastrectomy (LSG) as an isolated primary and secondary operation after failed gastric banding. METHODS Between May 2004 and October 2007, a total of 70 patients (female 77%, mean age 43 (21-65) years, mean initial body mass index (BMI) 46 (35-61) kg/m(2)) were prospectively(More)
BACKGROUND We investigated the outcome predictors of laparoscopic gastric banding (LAGB) for morbidly obese patients. METHODS From December 1996 to November 2004, a total of 380 consecutive unselected patients (78% female; median age 40 yr, range 17-66; body mass index 44.3 kg/m(2), range 35-75) were prospectively evaluated and underwent LAGB.
