Abstract

Introduction. Laparoscopic treatment of deep endometriosis (DE) is associated with intra- and post-operative morbidity. New technological developments, such as haptic feedback in laparoscopic instruments, could reduce the rate of complications. The aim of this study was to assess the room for improvement and potential cost-effectiveness of haptic feedback instruments in laparoscopic surgery. Methods. To assess the potential value of haptic feedback, a decision analytical model was constructed. Complications that could be related to the absence of haptic feedback were included in the model. Costs of complications were based on the additional length of hospital stay, operating time, outpatient visits, reinterventions, and/or conversions to laparotomy. The target population consists of women who are treated for DE in the Netherlands. A headroom analysis was performed to estimate the maximum value of haptic feedback in case it would be able to prevent all selected intra- and post-operative complications. Results. A total of 9.7 intraoperative and 47.0 post-operative complications are expected in the cohort of 636 patients annually treated for DE in the Netherlands. Together, these complications cause an additional length of hospital stay of 432.1 days, 10.2 additional outpatient visits, 73.9 reinterventions, and 4.2 conversions. Most consequences are related to post-operative complications. The total additional annual costs due to complications were €436 623, amounting to €687 additional costs per patient. Discussion. This study demonstrated that the potential value for improvement in DE laparoscopic surgery by using haptic feedback instruments is considerable, mostly caused by the potential prevention of major post-operative complications.
