Anastomotic leak in colorectal surgery: are 75 % preventable?

Area of Science:

• Colorectal Surgery
• Surgical Techniques
• Patient Outcomes

Background:

• Anastomotic leak (AL) is a serious complication of colorectal surgery, leading to increased morbidity, mortality, and healthcare costs.
• Effective strategies to minimize AL are crucial for improving surgical outcomes.

Purpose of the Study:

• To compare the anastomotic leak rates between end-to-end (E-E) and side-to-end (S-E) anastomosis techniques.
• To evaluate the impact of different risk factors on leak rates for each technique.

Main Methods:

• Retrospective analysis of colorectal resections involving E-E versus S-E anastomosis.
• Comparison of leak rates and associated risk factors between the two anastomosis groups.

Main Results:

• A total of 382 E-E and 363 S-E anastomoses were analyzed.
• The anastomotic leak rate was significantly lower with S-E (1.93%) compared to E-E (8.64%) (p < 0.001).

Conclusions:

• The side-to-end anastomosis technique is associated with a significantly reduced rate of anastomotic leak.
• Implementing S-E anastomosis may be a key strategy to improve safety and reduce complications in colorectal surgery.
