Introduction:
Laparoscopic-assisted total proctocolectomy and ileal pouch-anal anastomosis (Lap-IPAA) is a standard surgical procedure for patients with ulcerative colitis (UC), but its operative time can be prolonged due to technical complexity and disease-specific factors. This study aimed to identify risk factors associated with prolonged operative time in hand-sewn Lap-IPAA.
Methods:
This retrospective single-center study included 156 patients with UC who underwent hand-sewn Lap-IPAA between January 2018 and June 2024. Patients receiving stapled IPAA or open surgery were excluded. Clinical, laboratory, surgical, and perioperative data were collected from electronic records. Prolonged operative time was defined as ≥ 370 min (75th percentile). Univariate and multivariate logistic regression analyses were performed to identify independent risk factors.
Results:
Among the 156 patients, 40 (25.6%) were classified into the prolonged operative time group. Male sex (80.0% vs. 51.7%, p = 0.002) and higher BMI (21.7 vs. 18.6 kg/m2, p < 0.001) were significantly more common in the prolonged group. Multivariate analysis confirmed male sex (OR, 5.153; 95% CI, 1.927-13.779; p < 0.001) and BMI (OR, 1.323; 95% CI, 1.146-1.526; p < 0.001) as independent risk factors. Other variables, including UC severity, albumin, CRP, and preoperative immunosuppressive therapies, were not significantly associated with operative time.
Conclusion:
Male sex and elevated BMI were independently associated with prolonged operative time in hand-sewn Lap-IPAA for UC. These findings highlight the importance of preoperative planning and support the centralization of complex UC surgeries to experienced centers, particularly for high-risk patients.

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
