[SIDE-TO-END ANASTOMOSIS IN LOW ANTERIOR RECTAL RESECTION].

Area of Science:

• Colorectal Surgery
• Surgical Oncology
• Gastrointestinal Function

Background:

• Low anterior rectal resection is a common procedure for rectal cancer.
• Optimizing functional outcomes post-resection is crucial for patient quality of life.
• Different anastomosis techniques may impact postoperative function.

Purpose of the Study:

• To compare the functional results of straight coloanal versus side-to-end anastomosis.
• To evaluate postoperative stool frequency and anal sphincter function.
• To assess rectal compliance following low anterior rectal resection.

Main Methods:

• Prospective randomized study initiated in 2012.
• Inclusion of 40 patients in each group: straight coloanal (control) and side-to-end (main) anastomosis.
• Focus on patients with uncomplicated rectal cancer in the medium-ampullar section.

Main Results:

• The side-to-end anastomosis group demonstrated lower postoperative stool frequency.
• Patients in the main group exhibited less damage to the internal sphincter function.
• Higher rectal compliance rates were observed in the side-to-end anastomosis group.

Conclusions:

• Side-to-end anastomosis appears superior for functional outcomes after low anterior rectal resection.
• This technique may preserve internal sphincter function and improve rectal compliance.
• Further research can validate these findings for rectal cancer surgery.
