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.

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.

Use of collagen wrap from bovine origin for the management of colic perforation. Preliminary study in a pig model.

Introduction: The prevention or the management of digestive fistulae may be performed by using an external wrap of collagen of animal origin. To evaluate this treatment, an experimental study creating a hole in the colon of pig covered by a resorbable collagen belt was performed. Results are very interesting and collagen wrap is very well tolerated by the colon wall.

Is collagen a good banding material for outlet control of vertical gastroplasty? Preliminary study in pigs.

Background: To maintain the long-term effects of a gastric bariatric operation, bands are often placed to control the restriction. Erosion into the gastric wall by these devices remains a problem. A soft resiliant prosthesis of animal origin, constituted by a network of non-absorbable collagen fibres, may be a solution to this problem.

Simultaneous aberrant left and right gastric veins draining directly into the liver.

Aberrant gastric veins draining directly into the liver are rare variations of the portal vein system. We report on an autopsy in which both right and left gastric veins drained directly into the liver without joining the portal vein. Although the left gastric artery adopted a standard disposition, the left gastric vein was indeed found to ascend from the lesser curvature through the upper part of the lesser omentum.
