Intracorporal isoperistaltic linear colorectal “side-to-side” (overlap) anastomosis: invention concept and primary results

AIM: to present the primary experience of performing intracorporeal linear colorectal anastomosis using the “overlap” technique in laparoscopic anterior rectal resection. MATERIALS AND METHODS: the study presents the outcomes of intracorporeal linear “overlap” anastomosis in patients who underwent laparoscopic anterior rectal resection between October 2023 and February 2024. The results were evaluated based on various parameters including operation time, the postoperative morbidity rate (by Clavien-Dindo scale), conversion rates, hospital stay, quality of life by SF-36 questionnaire 30 days after surgery. RESULTS: the linear “overlap” anastomosis was done in 10 patients (5 females), aged 62.0 ± 9.03 years and BMI of 27.5 ± 7.2 kg/m 2 . No intraoperative complications occurred. One patient developed a seroma at the incision site (Clavien–Dindo I). The first bowel movement was at 1 (0–3) days after surgery. The post-op hospital stay was 5.7 ± 1.9 days. CONCLUSION: primary results demonstrate the simplicity and safety of intracorporeal linear “overlap” anastomosis technique. The further advanced study is justified.
