Treatment of postoperative peritonitis of small-bowel origin with continuous enteral nutrition and succus entericus reinfusion

HYPOTHESIS: Proximal intestinal stomas established by the exteriorization of leaking anastomosis in the presence of peritonitis can be used to reinfuse succus entericus and provide adequate enteral nutrition. DESIGN: Retrospective analysis of prospectively gathered data from a cohort of consecutive patients admitted between January 1993 and December 1999 for postoperative peritonitis requiring laparotomy and the construction of one or more small-bowel stomas. SETTING: Tertiary referral center with a surgical intensive care unit experienced in the treatment of intra-abdominal sepsis and succus entericus reinfusion. PATIENTS: Twenty-one consecutive patients with postoperative peritonitis originating from a jejunal or ileal leak. We excluded patients with established enterocutaneous fistulae, abscesses amenable to percutaneous drainage or other conservative treatments, and postoperative peritonitis caused by ileocolic or ileorectal anastomosis. INTERVENTIONS: Early laparotomy with exteriorization of small-bowel leak(s), and continuous enteral nutrition (CEN) and succus entericus reinfusion (SER) via the distal portion of the stoma until gastrointestinal continuity was restored. MAIN OUTCOME MEASURES: Feasibility of CEN and SER with temporary, diverting small-bowel stomas and their associated postoperative morbidity and mortality rates. RESULTS: One patient died, and 14 experienced complications. For technical reasons, CEN and SER were discontinued early on in 7 patients. The mean duration of CEN and SER was 58 days and 61 days, respectively. Enteral feedings allowed the suppression of central venous access after a median of 28 days, with 82 days as a median time to restoration of intestinal continuity. CONCLUSIONS: Although the exteriorization of small-bowel leaks with CEN and SER is generally feasible and effective in the treatment of critically ill patients with peritonitis secondary to small-bowel leaks, it is associated with significant morbidity and mortality, in part relating to patients' underlying diseases.
