Clinical Impact of Subcutaneous Fat Area on Incisional Hernia Development Following Laparoscopic Colorectal Cancer...

Area of Science:

• Surgical Oncology
• Abdominal Wall Reconstruction
• Laparoscopic Surgery

Background:

• Incisional hernia is a frequent complication post-colorectal surgery.
• Risk factors like visceral and subcutaneous fat are known, but abdominal wall musculature role is less studied.
• This study investigates anatomical features of the abdominal cavity and wall for incisional hernia risk factors.

Purpose of the Study:

• To identify anatomical risk factors for incisional hernia after laparoscopic colorectal resection.
• To evaluate the association between abdominal fat distribution and incisional hernia development.
• To inform prevention strategies for incisional hernia in patients undergoing colorectal surgery.

Main Methods:

• Retrospective analysis of 164 patients undergoing laparoscopic colorectal resection for cancer.
• Preoperative CT scans used to measure visceral and subcutaneous fat area.
• Median follow-up of 24 months to diagnose incisional hernia.

Main Results:

• Incisional hernia developed in 9.8% of patients within 18 months postoperatively.
• Univariate analysis showed female sex, BMI, visceral, and subcutaneous fat area as predictors.
• Multivariate analysis identified subcutaneous fat area as an independent risk factor (OR=5.839, p=0.018).

Conclusions:

• Subcutaneous fat area is independently associated with incisional hernia risk after laparoscopic colorectal resection.
• Meticulous fascial closure and tailored surgical approaches are crucial.
• Abdominal wall structure should be considered alongside fat indices for comprehensive risk assessment and prevention.
