Anastomosis to the rectum. Operative experience

Area of Science:

• Colorectal Surgery
• Surgical Techniques
• Gastrointestinal Surgery

Background:

• Anastomosis to the rectum is a critical step in colorectal surgery.
• Both stapled and hand-sutured techniques have been employed for rectal anastomosis.
• The choice of technique may influence complication rates and the need for diversion.

Purpose of the Study:

• To compare the outcomes of stapled versus hand-sutured anastomoses in rectal surgery.
• To evaluate complication rates, reoperation rates, and the need for diverting stomas.
• To assess the safety and efficacy of both techniques for very low rectal anastomoses.

Main Methods:

• Retrospective review of 466 consecutive rectal anastomosis procedures (March 1969 - December 1982).
• Categorization of anastomoses into stapled (n=396) using GIA or EEA instruments and hand-sutured (n=70).
• Analysis of diverting stoma construction, reoperation rates, and anastomotic complications.

Main Results:

• Stapled anastomoses had a lower reoperation rate (1.5%) compared to hand-sutured (8.6%).
• Diverting stomas were required less frequently with stapled (10%) versus hand-sutured (84%) anastomoses.
• Both techniques allowed for safe construction of very low anastomoses (0-5 cm from dentate line).

Conclusions:

• Stapling instruments are a safe and effective alternative to hand-suturing for rectal anastomosis.
• Stapled techniques are associated with significantly lower rates of complications and need for diversion.
• The decision for permanent colostomy should be based on disease factors, patient health, and anatomy, not solely on anastomotic technique.
