[Colon anastomosis: single-layer (row) suture (author's transl)].

Area of Science:

• Gastrointestinal Surgery
• Surgical Techniques
• Comparative Studies

Background:

• Anastomosis is a critical step in large-bowel resection surgery.
• Choosing the optimal anastomosis technique is crucial for patient outcomes.
• Previous studies have yielded mixed results regarding suture techniques.

Purpose of the Study:

• To compare the complication rates of single-row versus double-row anastomosis in large-bowel resection.
• To evaluate the impact of different anastomosis techniques on healing and revascularization.
• To determine the preferred suture method for minimizing adverse events.

Main Methods:

• A comparative study involving 622 patients undergoing large-bowel resection.
• Evaluation of complication rates associated with single-row and double-row anastomosis.
• Animal studies (dogs and rats) were conducted to validate findings.
• Assessment of healing process and revascularization in both techniques.

Main Results:

• Single-row anastomosis was associated with a significantly lower rate of complications.
• Double-row sutures prolonged the healing process and delayed revascularization.
• Intramural abscess and stenotic intraluminal roll formation were observed with double-row sutures.
• These adverse events were not present in the single-row anastomosis group.

Conclusions:

• Single-row anastomosis is superior to double-row techniques for large-bowel resection.
• The single-row technique facilitates faster healing and reduces surgical complications.
• Findings in animal models support the clinical observations, reinforcing the benefits of single-row anastomosis.
