Prepyloric antrectomy, truncal vagotomy, and front pylorotomy for the treatment of duodenal ulcer.

We have performed a suprapyloric antrectomy with anterior pylorotomy and truncal vagotomy in 106 patients with chronic duodenal ulcer between 1975 and 1990. Follow-up was carried out in 94 patients, during a mean time of 6 years. We have had no postoperative mortality and no long-term recurrence.

[The treatment of a simple pancreatic pseudoaneurysm or one associated with hemosuccus pancreaticus].

When a permanent communication occurs between an artery and a pancreatic pseudocyst, the pseudocyst becomes a pseudoaneurysm. Pancreatic pseudoaneurysms are primarily found in patients with alcoholic chronic pancreatitis. Fistulization of a pseudoaneurysm into the main pancreatic duct results in ductal hemorrhage.

Exteriorized colonic anastomosis.

The risk of anastomotic failure in the unprepared colon is generally high. Therefore, Hartmann's operation is frequently employed in emergencies. We present an alternative technique, the exteriorized anastomosis described until now only for cases of perforation.

[Histopathologic changes seen during the reopening of the intestinal lumen after obliteration of the digestive tract with nonabsorbable material. Experimental study in the rat].

The constant pressure exerted by occlusive ligation on the intestinal wall produces ischemia and ulceration of the mucosa, interruption of the muscular layer and transmural inflammatory reaction, which terminates when the ligature is eliminated and the injured tissues are repaired.
