Percutaneous gastrostomy for treating dilatation of the bypassed stomach after bariatric surgery for morbid obesity.

Objective: Retrospective analysis was performed to determine the safety and effectiveness of percutaneous gastrostomy for treating distention of the bypassed stomach after gastric bypass for morbid obesity.

Materials And Methods: Eight patients with morbid obesity and Roux-en-Y gastric bypass underwent percutaneous radiologic gastrostomy for postoperative decompression of the bypassed stomach. Four patients underwent gastrostomy on the fourth day after surgery: two in the early postoperative period (< or = 30 days after surgery) and two in the late postoperative period (6, 11 months after the procedure).

Bilateral smooth-muscle tumors of the adrenals in a child with AIDS.

We report a case of bilateral smooth muscle tumors (SMT) involving the adrenal glands in an 11-year-old female with acquired immunodeficiency syndrome (AIDS). The SMT of the right adrenal gland extended into the inferior vena cava, producing a tumor thrombus.

Reduction of adhesion formation by intraperitoneal administration of Arg-Gly-Asp-containing peptides.

Objective: To evaluate the ability of a variety of peptides containing the Arg-Gly-Asp (RGD) sequence to reduce the formation of intraperitoneal adhesions in a rabbit model.

Design: Prospective, randomized, double-blinded study.

Setting: University-based laboratory.

Reduction of adhesion formation by intraperitoneal administration of various anti-inflammatory agents.

Adhesion formation is a major source of postoperative morbidity and mortality. Therefore, the reduction of postoperative adhesion formation would be of clinical benefit. Various modalities have been shown to reduce adhesion formation, including fibrinolytic enzymes, nonsteroidal anti-inflammatory drugs, and barriers that reduce the apposition of sites of potential adhesion formation.
