Randomized Controlled Trial Comparative Study Clinical Trial
Preoperative versus postoperative endoscopic retrograde cholangiopancreatography in mild to moderate gallstone pancreatitis: a prospective randomized trial.
To determine whether endoscopic retrograde cholangiopancreatography (ERCP) and common bile duct (CBD) stone extraction should be performed routinely before surgery or'selectively after surgery in patients with mild to moderate gallstone pancreatitis. ⋯ In patients with mild to moderate gallstone pancreatitis without cholangitis, selective postoperative ERCP and CBD stone extraction is associated with a shorter hospital stay, less cost, no increase in combined treatment failure rate, and significant reduction in ERCP use compared with routine preoperative ERCP.

Liver adenomatosis (LA) is a rare disease originally defined by Flejou et al in 1985 from a series of 13 cases. In 1998, 38 cases were available for analysis, including eight personal cases. The aim of this study was to review and reappraise the characteristics of this rare liver disease and to discuss diagnosis and therapeutic options. ⋯ Liver adenomatosis is a rare disease, more common in women, where outcome and evolution vary and are exacerbated by estrogen intake. Most often, conservative surgery is indicated. Liver transplantation is indicated only in highly symptomatic and aggressive forms of the disease.

To assess the impact of possible risk factors on intestinal resection and postoperative recurrence in Crohn's disease (CD) and to evaluate the disease course. ⋯ Three of four patients with CD will undergo an intestinal resection; half of them will ultimately relapse. The extent of disease at diagnosis and the presence of perianal fistulas have an impact on the risk of surgery and the risk of postoperative recurrence. Women run a higher risk of postoperative recurrence than men. The frequency of surgery has decreased over time, but the postoperative relapse rate remains unchanged.

To study the ability of bombesin (BBS) to recover gut-associated lymphoid tissue (GALT) and preserve immunity in a lethal model of Pseudomonas aeruginosa (Ps) pneumonia in mice receiving total parenteral nutrition (TPN). ⋯ The results demonstrate that BBS reverses TPN-induced changes in GALT and preserves mucosal immunity. Ps immunization reduces the death rate in a gram-negative pneumonia model and maintains gastrointestinal and respiratory immunity in Ps immune mice receiving IV TPN.

Carcinomas of the colon and rectum are the third leading cause of cancer-related deaths. Although advances in the surgical treatment of primary colorectal cancers have lead to improvements in patient survival at early tumor stages, treatment of more progressive cancers has not resulted in dramatic improvements in patient survival. However, the selection of patient subgroups based on their prognosis and other characteristics could result in improved outcomes from adjuvant therapies in patients with Dukes B and C carcinomas. ⋯ Although data exist on the prognostic values of certain cell surface markers, the use of multivariate analysis for the identification of valuable prognostic factors remains uncommon. Using reproducible and standardized multivariate analysis procedures, new tumor markers should be carefully examined for their biologic and prognostic relevance before being considered as potentially useful in the management of colorectal cancers.
