Abstract
BACKGROUND: Gastrointestinal fistulization (GIF) is a rare and potentially fatal complication of acute necrotizing pancreatitis (ANP). There is paucity of data on clinical course and outcome of GIF in walled of necrosis (WON). OBJECTIVE: To evaluate frequency, clinical as well as imaging findings and outcome of spontaneous symptomatic GIF in patients with WON. METHODS: Retrospective analysis of database of patients with asymptomatic WON on regular follow-up over last six years to identify patients with symptomatic GIF. RESULTS: Out of 138 patients with asymptomatic WON seen during the study period, 16 (11.5%) patients (all males; mean age 41.7 ± 9.9 years) developed symptomatic GIF. The mean size of WON in patients who developed GIF was 9.5 ± 2.4 cm, and fistulization occurred after 65.1 ± 17.8 days of the onset of ANP. The site of fistulization was stomach, duodenum, jejunum, colon, and esophagus in seven (43.7%), five (31.2%), one (6.2%), two (12.5%), and one (6.2%) patients, respectively. GIF resulted in spontaneous resolution in two patients (stomach 1 and esophagus 1). The remaining patients with gastric (six patients) and duodenal (five patients) fistulization were successfully treated endoscopically by placing multiple plastic stents in the necrotic cavity after balloon dilatation of the fistulous tract. Patients with colonic fistulization required surgery. None of the patients succumbed to the illness. CONCLUSION: Symptomatic GIF of WON usually occurs within the first three months of onset of ANP. It commonly occurs in either stomach or duodenum and can be successfully managed endoscopically.
