Evaluation of a polyester collagen-coated heparin bonded vascular graft.

This animal study was designed to compare a collagen coated heparin bonded vascular graft (CHG) versus a collagen coated vascular graft (CG) regarding intraoperative blood loss and healing process. 24 polyester vascular grafts (12 CHG and 12 CG) of 6 mm in diameter and 5 mm in length were implanted between the common iliac and external iliac artery in 12 adult dogs. The grafts were explanted between the first and the sixth months which followed the implantations.

[Antral exclusion. A complement to palliative gastrojejunal shunt in pancreatic cancer].

Objectives: Prophylactic gastrojejunostomy remains a controversial issue in the management of unresectable pancreatic cancer. The main disadvantage of the gastrojejunostomy being the postoperative delayed gastric emptying (gastroparesia and circulus vitiosus through the nonobstructed duodenum). In the aim to reduce the effects of delayed gastric emptying we advocated the adjunct of an antral exclusion to simplify antrectomy by eliminating antral dysfunction and duodenal circulus vitiosus.

High morbidity rate after converted laparoscopic colorectal surgery.

Sixteen of 65 laparoscopically assisted colorectal operations were converted to an open procedure, usually because of dissection difficulties. Conversion was decided early in the procedure in four cases without perioperative morbidity and later in 12 cases, after a mean of 56 min. The results in patients undergoing converted operation were compared with those in 252 having a planned open colorectal procedure during the same period.

[Appendiceal mucoceles. Pathophysiology and therapeutic indications].

Appendiceal mucoceles (AM) are rare lesions of the appendix, characterized by an accumulation of mucus. Two main pathogenic mechanisms may be invoked to explain their development. Firstly, AM are secondary to an obstruction of the appendiceal lumen for a wide variety of reasons.
