OBJECTIVE: Understanding factors for prolonged operative time is essential for surgery. This study aims at identifying the factors related to prolonged ileostomy closure operation time.

PATIENTS AND METHODS: The data of 88 patients who underwent ileostomy reversal in the Department of Gastrointestinal Surgery of Jiaxing First Hospital between January 2018 and October 2021 were retrospectively analyzed. Prolonged operation time was defined as operative time >65 minutes. The Chi-square test was used to compare data between patients with normal operative time (≤65 minutes) and patients with prolonged operative time. Univariate and multivariate logistic regression analyses were performed to identify the factors associated with prolonged ileostomy closure operation time.

RESULTS: Among the 88 patients (mean age: 62.78 years), median ileostomy retention time was 127.50 (range: 61.00-1,192.00) days. The operation time ranged from 35.00 minutes to 125.00 minutes. Prolonged ileostomy closure time occurred in 41 (46.6%) patients. In univariate analysis, the factors associated with prolonged operation time were body mass index (BMI) ≥25 kg/m2, previous history of abdominal surgery, and manual suture. History of serious complications after the primary operation was associated with shorter operation time. In multivariate analysis, the independent risk factors for prolonged operation time were BMI ≥25 kg/m2 (OR = 4.552, 95% CI: 1.369-15.136, p = 0.013), previous history of abdominal surgery (OR = 4.377, 95% CI: 1.394-13.739, p = 0.011), and manual suture (OR = 3.941, 95% CI: 1.181-13.154, p = 0.026).

CONCLUSIONS: Overweight, previous history of abdominal surgery, and manual suture appear to be risk factors for prolonged operative time for ileostomy closure.
