Prevalence, diagnosis, and surgical management of complex ileocolic-duodenal fistulas in Crohn's disease.

BACKGROUND: The aim of the present study was to review the prevalence and surgical management of patients with Crohn's disease (CD) complicated by ileocolic-duodenal fistulas (ICDF). METHODS: We performed a retrospective chart review of CD patients who underwent surgical takedown and repair of ICDF during January 2011-December 2021 at two inflammatory bowel disease referral centers. RESULTS: We identified 17 patients with ICDF (1.3%) out of 1283 CD patients who underwent abdominal surgery. Median age was 42 (20-71) years, 13 patients were male (76%) and median body mass index was 22.7 (18.4-30.3) kg/m2. Four patients (24%) were diagnosed preoperatively and only 2 (12%) were operated on for ICDF-related symptoms. The most common procedure was ileocolic resection (13 patients, 76%) including 4 repeat ileocolic resections (24%). The duodenal defect was primarily repaired in all patients with no re-fistulization or duodenal stenosis, regardless of the repair technique. A laparoscopic approach was attempted in the majority of patients (14 patients, 82%); however, only 5 (30%) were laparoscopically completed. The overall postoperative complication rate was 65% including major complications in 3 patients (18%) and 2 patients (12%) who required surgical re-intervention for abdominal wall dehiscence and postoperative bleeding. Preoperative nutritional optimization was performed in 9 patients (53%) due to malnutrition. These patients had significantly less intra-operative blood loss (485 vs 183 ml, p = 0.05), and a significantly reduced length of stay (18 vs 8 days, p = 0.05). CONCLUSION: ICDF is a rare manifestation of CD which may go unrecognized despite the implementation of a comprehensive preoperative evaluation. Although laparoscopic management of ICDF may be technically feasible, it is associated with a high conversion rate. Preoperative nutritional optimization may be beneficial in improving surgical outcomes in this select group of patients.

Options and strategies for the management of choledocholithiasis.

The introduction of laparoscopic techniques for the management of biliary stone disease has expanded the therapeutic choices for surgeons confronted with choledocholithiasis. As new strategies emerge, the treatment of cholelithiasis and choledocholithiasis remains controversial. This paper discusses the options available for the treatment of common bile duct stones. Diagnostic and therapeutic algorithms are proposed. The treatment of these patients must be individualized, taking into consideration the condition of the patient, associated diseases, secondary complications of the gallstones, and the surgical expertise and resources of the institution.
