Iatrogenic intestinal injury concomitant to iatrogenic bile duct injury: The second component

Objective. Bile duct injuries have a frequency of 0.1% to 0.3% even in the most experienced centers. Complex biliary lesions usually require a bilioenteric anastomosis, achieving good long-term results in 80% to 90% of the cases. Besides injuries to the abdominal contents during laparoscopy (by trocars or electrocautery), intestinal complications associated with reconstruction attempts can be observed. We analyzed the concomitant intestinal complications in 251 patients with iatrogenic biliary injuries reconstructed over this 12-year period. Methods. A retrospective review of patients with biliary tract reconstruction after iatrogenic injury in a tertiary academic health-care center was done. All patients with concomitant intestinal injury were included; type of operation and postoperative outcome were analyzed. Results. Among 251 patients, 35 cases had a concomitant intestinal injury. The most common site of fistulization was the duodenum (18 cases, 50%); 9 cases were associated with long-term subhepatic drains (more than three weeks), and the other 9 cases were associated with a dehiscent hepatoduodenostomy. Faulty Roux-en-Y reconstruction was observed in 5 cases. In 5 cases, fistulization of the jejunum and ileum, secondary to drain placement, was documented, as well as 3 cases with colonic injuries. Two patients had a dehisced Roux-en-Y anastomosis. One had a bilioenteric omega type ileal anastomosis, and 1 had a hepatoileal anastomosis without omega reconstruction. Primary repair of the duodenum with resection of the affected intestinal or colonic segment was done at the same time of biliary repair without related morbidity. Conclusions. Concomitant gastrointestinal injures were found with an incidence of 15% in our series. The most common site of fistulization is the duodenum. In half of the patients, it was secondary to a dehiscent hepatoduodenostomy, whereas in the other, it was caused by long-term subhepatic drains. Besides faulty Roux-en-Y reconstruction, fistulization was related with long-term drains. Primary repair and resection of the affected segment of jejunum, ileum, and colon can be done during the same operative stage of biliary reconstruction, without significant correlated mortality.
