Laparoscopic Distal Pancreatectomy in Benign or Premalignant Pancreatic Lesions: Is It Really More Cost-Effective than Open Approach?

BACKGROUND: Data regarding the quality of life in patients undergoing laparoscopic distal pancreatectomy are lacking and no studies have reported a real cost-effectiveness analysis of this surgical procedure. The aim of this study was to evaluate and compare the quality of life and the cost-effectiveness of a laparoscopic distal pancreatectomy with respect to an open distal pancreatectomy. METHODS: Forty-one patients who underwent a laparoscopic distal pancreatectomy and 40 patients who underwent an open distal pancreatectomy were retrospectively studied as regards postoperative results, quality of life and cost-effectiveness analysis. The Italian neutral version of the European Organization for Research and Treatment of Cancer Quality-of-Life Questionnaire C-30, version 3.0, was used to rate the quality of life. RESULTS: Postoperative results were similar in the two groups; the only difference was that the first oral intake took place significantly earlier in the laparoscopic group than in the open group (P < 0.001). Regarding quality of life, the laparoscopic approach was able to ameliorate physical functioning (P = 0.049), role functioning (P = 0.044) and cognitive functioning (P = 0.030) and reduce the sleep disturbance scale (P = 0.050). The cost-effectiveness analysis showed that the acceptability curve for a laparoscopic distal pancreatectomy had a higher probability of being more cost-effective than an open distal pancreatectomy when a willingness to pay above 5400 Euros/quality-adjusted life years (QALY) was accepted. CONCLUSION: Despite the limitations of the study, laparoscopic distal pancreatectomy can be considered not only safe and feasible but also permits a better quality of life and is acceptable in terms of cost-effectiveness to Italian and European health care services.
