Initial 30 cholecystectomy procedures performed with the Senhance digital laparoscopy system.

PURPOSE: The Senhance digital laparoscopy system (SDLS) is a novel platform developed for digitization in endoscopic surgery. This retrospective study aimed to evaluate the short-term outcome in the initial 30 consecutive patients.

METHODS

SDLS cholecystectomies were performed in 30 consecutive patients (13 male, 17 female) by a single surgeon from September 2020 to March 2022. The patients' median age (range) was 77.5 (27-82) years, and median body mass index was 23.3 (19-38) kg/m2 . Four trocars were used, three of which were docked to manipulator arms of the SDLS. Surgical procedures performed with the SDLS were almost the same as those by conventional surgery.

RESULTS

Median docking time, cockpit time, and operation time in minutes were 4 (3-13), 34 (13-81), and 69 (47-201), respectively. Operation time after the sixth case tended to shorten compared with that for the initial five cases. Three cases (10%) were converted to conventional laparoscopic surgery due to severe cholecystitis, but none required conversion to open surgery. Postoperative complications of Clavien-Dindo grade ≥II were not observed.

CONCLUSION

This retrospective study showed that cholecystectomy using the SDLS appeared to be safe and feasible in limited cases without severe inflammation.
