Extracorporeal versus intracorporeal anastomosis after laparoscopic right hemicolectomy: cost-effectiveness analysis.

Le résumé fourni par la source

AIM: The cost effectiveness of the laparoscopic right hemicolectomy is still debated, and the current literature does not allow to be drawn certain conclusion. Our study compared direct clinical costs and outcomes for laparoscopic right hemicolectomy with the two most used type of anastomosis, such as ExtraCorporeal Anastomosis (ECA) and IntraCorporeal Anastomosis (ICA). MATERIAL AND METHODS: In this retrospective study, all patients who underwent laparoscopic right hemicolectomy with intracorporeal and extracorporeal anastomosis between January 2016 and April 2018 were evaluated. Patients were divided into two groups according to the type of anastomosis: ECA or ICA. RESULTS: Thirty ECA and twenty-nine ICA patients were included in the study. Operative time was significantly longer in ICA group than ECA group (p < 0.001). No significant differences between the groups were seen in terms of timeto- first flatus, postoperative complications and re-admission rate. ICA group showed a shorter hospitalization (5 vs 6; p < 0.022). In the ICA group, considering only the surgical tools were more expensive than in ECA (1435.6 € vs 72 €). Nevertheless, the total cost of the two procedures in similar (14451.36 € in ECA group vs 14631.04 € in ICA group). CONCLUSION: ECA and ICA are comparable in terms of postoperative outcomes. ICA requires much more expensive charges, compared to a minor hospitalization. The ECA seems to be less expensive in terms of surgical supplies but the longer recovery determines an increase in the total cost resulting in a non-inferiority of one compared to the other technique. KEY WORDS: Cost-analysis, ExtraCorporeal Anastomosis, IntraCorporeal Anastomosis, Laparoscopy, Right Hemicolectomy.
