A Double Suspension Technique for Laparoscopic Isolated Caudate Lobectomy

Background: Laparoscopic isolated caudate lobectomy is still a challenging procedure for hepatobiliary surgeons because of its deep location and narrow operating space. Hilar exposure and adequate operation space play an important role during laparoscopic caudate lobectomy. Very few references are available on this technique, and in this study, we present a new suspension technique to assist laparoscopic caudate lobectomy.Materials and Methods: The data of patients with caudate hepatic tumors who underwent laparoscopic isolated caudate lobectomy with or without the double suspension technique at the Eastern Hepatobiliary Surgery Hospital were retrospectively analyzed.Results: A total of 25 patients underwent laparoscopic isolated caudate lobectomy at Eastern Hepatobiliary Surgery Hospital between June 2016 and March 2022. Eight patients had perioperative complications, and no patient died within 30 days after surgery. There were no significant differences between the two groups in terms of conversion rate (8.3% versus 7.7%; P = .954), complication rate (25.0% versus 38.5%; P = .480), length of stay (8.0 [6.0-11.0] days versus 9.0 [6.0-19.0] days; P = .098), and postoperative liver function changes. Patients who underwent resection in the suspension group had shorter operation time (154.9 +/- 44.3 minutes versus 224 +/- 86.3 minutes; P = .018), inferior vena cava dissection time (30.1 +/- 5.4 minutes versus 44.8 +/- 7.4 minutes; P < .001), and less bleeding (125.0 [20-800.0] mL versus 350 [80-850.0] mL, P = .011).Conclusions: This double suspension technique is a safe and feasible method to assist laparoscopic caudate lobectomy. It provides clear exposure and adequate surgical space, thereby shortening the operation time and reducing intraoperative blood loss.
