Comparative StudyMalabsorptive gastric bypass in patients with superobesity.
Weight loss in superobese patients has been problematic after conventional gastric restrictive operations including conventional Roux-en-Y gastric bypass (RYGB). The goal of the present study was to compare weight loss in patients with superobesity (body mass index > or =50 kg/m(2)) using a distal RYGB (D-RY) in which the Roux-en-Y anastomosis was performed 75 cm proximal to the ileocecal junction (N = 47) vs. patients who had Roux limbs of 150 cm (N = 152) and 50 to 75 cm (N = 99). All operations incorporated the same gastric restrictive parameters. ⋯ However, the greater incidence of metabolic sequelae after D-RY vs. RYGB-150 cm calls into question its routine use in superobese patients undergoing bariatric surgery. We conclude that some degree of malabsorption should be incorporated into bariatric operations performed in superobese patients to achieve satisfactory long-term weight loss.

Comparative StudyEn bloc resection for locally advanced cancer of the pancreas: is it worthwhile?
The benefit of radical surgical resection of contiguously involved structures for locally advanced pancreatic cancer is unclear. The aim of this study was to examine patient outcome after extended pancreatic resection for locally advanced tumors and to determine if any subset of extended resection affected outcome. We retrospectively reviewed the records of 116 patients with adenocarcinoma of the pancreas, who underwent extirpative pancreatic surgery between 1987 and 2000. ⋯ In comparing patients in group I, who underwent vascular resection vs. mesocolon (colon or middle colic vessels) resection, the median survival was 26 months and 19 months, respectively (P = 0.12). We were unable to detect a difference in outcome for patients with locally advanced cancers requiring extended pancreatic resections compared to patients with standard resections. En bloc resection of involved surrounding structures, to completely extirpate all macroscopic disease, may be of benefit in selected patients with locally advanced disease, particularly when combined with preoperative chemoradiation therapy.

Ninety-five cases of intestinal transplantation at the University of Miami.
Intestinal failure requiring total parenteral nutrition (TPN) is associated with significant morbidity and mortality. Intestinal transplantation can be a lifesaving option for patients with intestinal failure who develop serious TPN-related complications. The aim of this study was to evaluate survival, surgical technique, and patient care in patients treated with intestinal transplantation. ⋯ Intestinal transplantation can be a lifesaving alternative for patients with intestinal failure. The prognosis after intestinal transplantation is better when it is performed before the onset of liver failure. Rejection monitoring with zoom videoendoscopy and new immunosuppressive therapy with sirolimus, daclizumab, and campath-1H have contributed to the improvement in patient survival.
