Massive weight loss induced by gastric bypass reduces IL-18, TNFR2 and CRP. IL-18 might be a marker of the chronic inflammatory process underlying insulin resistance but its lack of association with anthropometric and body composition parameters does not support a major secretion by human adipocytes. IL-18 and sTNFR1 and -2 do not play a main role in the inhibition of the secretion of adiponectin.

Resection, on-table lavage and primary anastomosis constitute the operation of choice for selected patients with left colonic emergency.

Our experience suggests that laparoscopic surgery in the elderly is safe, is associated with short hospital stay, and produces less morbidity and mortality. Therefore, it should be adopted widely if the expertise in the area of laparoscopic surgery is available for this group of patients.

To determine if ischemic conditioning of the stomach improves the morbidity, mortality, and the anastomotic failure in gastroplasties with cervical anastomosis. Analysis of all patients with indication for cervical gastroplasty during the period of study. In all cases, ischemic conditioning was performed by selective embolization. Anastomotic failure, morbidity, and mortality rates were studied. Thirty-nine consecutive patients were included. Angiography and selective embolization of the left gastric, right gastric, and splenic arteries were performed. Surgery was performed 2 weeks later. Four patients did not have a complete embolization; median hospital stay after conditioning was 1.24 ± 0.6 days. In two patients, surgery could not be completed. Of the 33 remaining, 29 had a posterior mediastinic gastroplasty and four through the anterior mediastinum. The most common morbidity was respiratory. Five patients had a reoperation and the mortality was 6%. One case of anastomotic leak was found (3%). The mean hospital stay was 17.5 days. Preoperative embolization is a technique with acceptable morbidity and a short hospital stay. In our experience it can reduce the incidence of the morbidity, mortality, and anastomotic leak in gastroplasties with cervical anastomosis. Prospective studies will be necessary to demonstrate the validity of this approach.
