Laparoscopic versus open central pancreatectomy: a propensity score-matched analysis in a single centre

Langenbecks Arch Surg. 2023 Jan 18;408(1):40. doi: 10.1007/s00423-023-02752-4.

Abstract

Purpose: Laparoscopic central pancreatectomy (LCP) has been implemented in pancreatic surgery; however, open surgery is still the predominant approach for central pancreatectomy (CP). Our objective was to compare LCP with open CP (OCP).

Methods: Data were collected from patients with tumours located in the pancreatic neck and proximal body who underwent CP in the Department of Pancreatic Surgery West China Hospital from January 1, 2010, to June 30, 2019. A comparison between the LCP and OCP groups was performed.

Results: Fifteen patients underwent CP via the laparoscopic approach, and 96 patients underwent CP via the open approach. Using 1:2 propensity score matching (PSM), 12 patients in the LCP group were matched to 21 in the OCP group. Regarding safety, postoperative pancreatic fistula (POPF) was not significantly different between the two groups (13.3% vs. 12.5%, P = 1.000), even with PSM (16.7% vs. 14.3%, P = 1.000). However, regarding effectiveness, the operative time in the OCP group was significantly shorter than that in the LCP group before (307.0 ± 92.3 ml vs. 220.6 ± 63.6 ml, P < 0.000) and after (300.3 ± 90.2 ml vs. 212.7 ± 44.4 ml, P = 0.002) PSM. Regarding length of stay (LOS), there was no difference between the two groups before (13.1 ± 13.7 days vs. 12.7 ± 10.1 days, P = 0.376) and after PSM (14.4 ± 15.1 days vs. 14.5 ± 16.2 days, P = 0.985). The length of the resected pancreas was shorter in the OCP group than in the LCP group before PSM (50.0 ± 13.2 mm vs. 41.1 ± 11.1 mm, P = 0.043). However, there was no difference between the two groups after PSM (47.9 ± 12.5 mm vs. 37.9 ± 10.4 mm, P = 0.084). Moreover, the other variables showed no difference between the two groups before and after PSM.

Conclusion: LCP can demonstrate similar safety and effectiveness to OCP, even in the early stages of the learning curve.
