Factors Associated With Prolonged Operative Times in Laparoscopic Right Hemicolectomy and Its Association With...

Area of Science:

• Surgical Oncology
• Minimally Invasive Surgery
• Colorectal Surgery

Background:

• Prolonged operative time in laparoscopic right hemicolectomy for colon cancer presents challenges.
• Identifying associated factors is crucial for optimizing surgical outcomes.

Purpose of the Study:

• To investigate factors associated with prolonged operative time during laparoscopic right hemicolectomy for colon cancer.
• To assess the impact of operative time on patient complications and hospital stay.

Main Methods:

• Retrospective review of 197 patients undergoing laparoscopic right hemicolectomy for colon cancer (2011-2021).
• Linear and binary logistic regression analyses were used to identify factors associated with operative time.
• Correlation analysis assessed the relationship between operative time and complications/hospital stay.

Main Results:

• Male sex (β=17.3, p=0.026) and extended hemicolectomy (β=67.7, p=0.001) were independently associated with longer operative times.
• Higher body mass index, American Society of Anesthesiologists (ASA) IV classification, and intracorporeal vessel control also correlated with increased operative duration.
• Operative times ≥160 minutes were associated with significantly longer hospital stays (5 vs. 4 days, p=0.043) but similar complication rates.

Conclusions:

• Male sex, advanced ASA classification, and extended hemicolectomy are significant predictors of prolonged operative time in this procedure.
• While longer operative times are linked to increased hospital stay, they do not appear to significantly elevate complication rates.
• These findings can inform surgical planning and patient management for laparoscopic right hemicolectomy.
