We compared the resolution over time of pulmonary atelectasis after a laparoscopic procedure by performing computed tomography scans in two different groups of patients: 1 group had 10 nonobese patients, and in the other group there were 20 morbidly obese patients.

LGB appeared promising during the first few years after its introduction, but results worsen over time, despite improvements in the operative technique and material. Only about 60% of the patients without major complication maintain an acceptable EWL in the long term. Each year adds 3-4% to the major complication rate, which contributes to the total failure rate. With a nearly 40% 5-year failure rate, and a 43% 7-year success rate (EWL >50%), LGB should no longer be considered as the procedure of choice for obesity. Until reliable selection criteria for patients at low risk for long-term complications are developed, other longer lasting procedures should be used.

Introduction : outre son effet bénéfique sur le poids, la chirurgie bariatrique améliore de façon considérable l'homéostasie glucide chez les patients diabétiques. Cette amélioration survient très tôt dans la période post-opératoire, avant que le poids ne soit réduit de manière importante. De plus, les interventions chirurgicales qui "court-circuitent" une partie de l'intestin grêle, telle que le by-pass gastrique, apparaissent être plus efficaces que les interventions purement restrictives, telles que le cerclage gastrique. Finalement, j'adresse mon ultime remerciement à ma mère pour le soutien qu'elle m'apporte depuis des années. Objectifs

Laparoscopic management of small bowel obstruction is possible in roughly 60% of the patients selected for this approach. Morbidity is lower, resumption of a normal diet is faster, and hospital stay is shorter than with patients requiring conversion. No clear predictor of success or failure was identified, but intraoperative complications must be avoided. If the surgeon is widely experienced in advanced laparoscopic surgery and there is a liberal conversion policy, laparoscopy is a valuable alternative to conventional surgery in the management of acute small bowel obstruction.

This study confirms the increased prevalence of GERD in the morbidly obese population. Upper GI endoscopy should be performed routinely during evaluation of morbidly obese patients for bariatric surgery. When both conditions coexist, effective treatment is probably best provided by Roux-en-Y gastric bypass, which produces effective weight loss and correction of pathological reflux.
