In a study led by Dr. Peng Sun from Tongren Hospital, 68 patients undergoing laparoscopic low anterior resection with a new manta-shaped anastomosis had no occurrences of anastomotic leakage or bleeding. Mean operative time was 176 minutes, and hospital stays averaged five days. The innovative technique aimed to mitigate risks from the double-stapling method by fully enclosing previously vulnerable regions. The study examined patients with sigmoid or rectal cancer, ruling out those who had previous therapies. However, the sample size and single-center design limit findings' broader application.
1. The study involved 68 patients with sigmoid or rectal cancer. 2. No anastomotic leakage or bleeding was reported postoperatively. 3. Mean operative time was 176 minutes with an average hospital stay of 5 days. 4. Manta-shaped anastomosis addresses risks of double-stapling technique. 5. Indocyanine green imaging assessed anastomotic perfusion. 6. Retrospective design limits long-term outcome evaluation. 7. Lack of control group affects comparative outcome assessment.
