Surgical management of chronic fistula after sleeve gastrectomy.

Background: There is no clear definition of the chronic leak after sleeve gastrectomy. There are several endoscopic approaches, including endoprothese, endoscopic clips, endoscopic sealing glue, or balloon dilation. In case of failure of the endoscopic treatment, a definitive surgical approach can be attempted.

Capture of viable circulating tumor cells in the liver of colorectal cancer patients.

Background: The incidence and number of circulating tumor cells (CTCs) in the peripheral blood of colorectal cancer patients are lower than in other cancer types, which may point to a particular biology of colorectal cancer affecting CTC detection.

Methods: We detected CTCs in the peripheral and mesenteric blood of colorectal cancer patients by use of 2 independent technologies on the basis of different biological properties of colon cancer cells. Seventy-five patients diagnosed with localized (M0, n = 60) and metastatic (M1, n = 15) colorectal cancer were included.

A review of available prosthetic material for abdominal wall repair.

Abdominal wall incisional and inguinal hernia repair can call for utilization of implants or prostheses as an alternative to simple suture techniques. The various implants can be synthetic, biologic or mixed: their physicochemical properties condition the mechanical results and the long-term outcome of the repair. The increasing number of available materials allows the surgeon to choose between a wide variety depending on the indication, the site of implantation, the surgical approach and whether the operative field is contaminated or not.

Post-operative adhesions after digestive surgery: their incidence and prevention: review of the literature.

Introduction: Post-operative adhesions after gastrointestinal surgery are responsible for significant morbidity and constitute an important public health problem. The aim of this study was to review the surgical literature to determine the incidence, consequences and the variety of possible countermeasures to prevent adhesion formation.

Methods: A systematic review of English and French language surgical literature published between 1995 and 2009 was performed using the keywords "adhesion" and "surgery".

Circulating epithelial cells in patients with benign colon diseases.

Background: Detection of circulating tumor cells (CTCs) in the peripheral blood is a rapidly developing research field with clear clinical implications for the staging and monitoring of cancer patients. Current CTC assays, including the US Food and Drug Administration-cleared CellSearch® system, typically use markers [e.g.
