Colon wound management and prograde colonic lavage in large bowel trauma.

Between 1983 and 1987 prograde colonic lavage was prospectively evaluated in 389 patients with colon trauma. Predefined high risk patients had exteriorization of the primarily sutured colon. Intraperitoneal primary closure was otherwise used. Patients received prograde colonic lavage by random allocation. The healing exteriorized colon was interiorized 5-10 days after the initial surgery. The median age was 29 years and only 28 patients were women. Injuries were due to stab (316), gunshot (54), shotgun (10) or blunt trauma (9). Exteriorization of the primarily sutured colon was carried out in 217 patients of whom 101 had prograde colonic lavage. Twenty (9 per cent) died. Of the survivors, 150 (76 per cent) had their colon successfully interiorized and this rate was unaffected by prograde colonic lavage. Intraperitoneal primary closure was performed in 172 patients of whom 91 had prograde colonic lavage. Seven (4 per cent) died. Mortality was directly related to the number of associated injuries. Prograde colonic lavage, irrespective of the type of colonic wound management used, did not reduce the mortality rate, which was 7.2 per cent for those who had such lavage and 6.6 per cent for the rest. Prograde colonic lavage cannot therefore be recommended in colon trauma.

Adaptation of jejunal to colonic mucosal autografts in experimentally induced short bowel syndrome.

The behavior of jejunal to colonic mucosal autografts was studied in an experimental animal model of short bowel syndrome (SBS). Histological appearances, enterocyte enzyme activities, and in vitro glucose transport were studied at the donor and recipient graft sites in control, short-bowel syndrome, and gastrocolic fistula 5-week-old Sprague-Dawley rats. Small intestinal function was maintained in the jejunocolonic graft after 80% small bowel resection; animals in which small bowel was not resected showed loss of graft function and enzyme activity. This effect is dependent on the presence of jejunal chyme: after gastrocolic fistulae, the jejunum to colon grafts lost jejunal functional activities. Total parenteral nutrition did not alter graft behavior but improved the postoperative mortality of the procedures. The results provide additional information on intestinal adaptation in SBS.

Parotid fistula: current management.

The most common cause of parotid fistula is trauma. Other causes include operative complications, infection, and malignancy. In the acute phase of ductal injury, primary reconstruction, if possible, is the treatment of choice. Acute parenchymal injury is treated by tight closure and expectancy. When diverting or flow-blocking measures fail to correct chronic ductal fistula, the treatment of choice for this situation as well as for chronic parenchymal fistula may be tympanic neurectomy, which can be done under local anesthesia, is associated with low morbidity, is relatively uncomplicated and has given excellent results to date in our hands.
