Comparative safety of intracorporeal versus extracorporeal anastomoses in laparoscopic right colectomy

Aim – to assess the safety of a hand-sewn intracorporeal ileo-transverse anastomosis. Material and methods. The retrospective study included patients from the Omsk Regional Cancer Registry from 2015 to 2023. It included patients with colon cancer (ICD-10 C18), who underwent a laparoscopic right colectomy. In the study group patients had hand-sewn intracorporeal anastomoses dene under an original method, terminus-terminal invagination ileo-transverse anastomosis; in the control group patients had hand-sewn ‘side-to-side’ extracorporeal anastomoses. Results. 89 patients were enrolled: 42 in the study group and 47 in the control group. No cases of anastomotic leakage were found in the study group versus 2 (4.3%) in the control group (p=0.496). Grade 3 and higher surgical morbidity was equal in both groups: 2 (4.8%) versus 5 (10.7%), p=0.550. Conclusion. The hand-sewn original intracorporeal anastomosis is safe and can be considered by experienced laparoscopic surgeons. Further study is needed for a detailed comparative analysis with established techniques.
