Prognostic factors for complications after loop ileostomy reversal

Area of Science:

• Gastroenterology
• Surgical Oncology
• Colorectal Surgery

Background:

• Defunctioning ileostomy creation and closure are associated with morbidity.
• Limited data exists on complications specifically after ileostomy closure.
• This study evaluates morbidity from loop ileostomy closure (LIC) and its relation to prior surgical complications.

Purpose of the Study:

• To assess the morbidity associated with loop ileostomy closure (LIC).
• To identify risk factors for postoperative complications after LIC.
• To determine if prior postoperative complications influence outcomes of stoma closure.

Main Methods:

• Retrospective study of prospectively registered patients undergoing elective LIC.
• Data collected on baseline characteristics and complications after primary surgery and LIC.
• Logistic regression analysis used to identify predictors of LIC complications.

Main Results:

• 37.4% of 428 patients experienced complications after LIC, most commonly paralytic ileus.
• Significant predictors for LIC complications included chronic kidney disease (OR 2.31), prior postoperative complications (OR 2.25), and LIC >10 months post-surgery (OR 1.52).

Conclusions:

• Patients with chronic kidney disease face higher risks of LIC complications.
• Previous postoperative complications significantly increase the likelihood of complications after LIC.
• Delayed loop ileostomy closure (beyond 10 months) is associated with increased postoperative morbidity.
