An extracorporeal and finely adjustable Pringle maneuver instrument for Laparoscopic Mesohepatectomy

Abstract

Background Laparoscopic mesohepatectomy remains in the exploratory stage because it is difficult to perform. Bleeding control is crucial for a successful operation. Our medical center has designed blocking forceps to perform the Pringle maneuver. This study aimed to investigate the value of these novel blocking forceps in laparoscopic mesohepatectomy. Methods Data from patients with malignant liver tumors who underwent laparoscopic mesohepatectomy between July 2017 and June 2022 were retrospectively collected. Patients who underwent the Pringle maneuver using novel blocking forceps were selected. The baseline data of all patients and the data of perioperative laboratory tests, imaging, and surgery-related parameters were statistically analyzed. Results All 61 patients who met the screening criteria underwent laparoscopic mesohepatectomy using novel blocking forceps for the Pringle maneuver. A total of 4 patients underwent an open surgery. Times of blocking was 2.92 ± 2.17, and the duration of blocking was 42.74 ± 33.00 minutes. Blood transfusions were performed in 6 patients, of whom 566.67 ± 150.55 ml were administered. All the patients underwent R0 resection. The complication rate was 8.2% in all cases. No deaths occurred. Conclusion Our designed blocking forceps for the Pringle maneuver in laparoscopic mesohepatectomy is conducive to the successful completion of surgery.
