Objective:

To evaluate the outcomes, including anastomotic integrity and postoperative complications, of a novel manta-shaped anastomosis technique in laparoscopic low anterior resection for patients with sigmoid colon or rectal cancer.

Approach:

Key Findings:

No anastomotic leakage, bleeding, or postoperative ileus observed in the cohort.
Mean operative time was 176 minutes, mean estimated blood loss was 67 mL, and mean postoperative hospital stay was 5 days.
Two patients developed postoperative fever unrelated to anastomotic complications.

Interpretation:

The manta-shaped anastomosis technique appears effective in preventing anastomotic complications in laparoscopic low anterior resection, with promising early outcomes.

Limitations:

Lack of a control group for comparative assessment limits the ability to draw definitive conclusions.
Modest sample size from a single center limits generalizability of the findings.
Retrospective design restricts evaluation of long-term outcomes and potential complications.

Conclusion:

The manta-shaped anastomosis may reduce the risk of anastomotic leakage and associated complications, but further studies with a control group are warranted to validate these findings.
