Deconstructing the Operative Times of Robotic Pancreaticoduodenectomy

Introduction Despite numerous benefits offered, robotic procedures take longer than “open” procedures. With the intent to reduce operative duration, we examined the degree each operative step contributes to operative duration in robotic pancreaticoduodenectomy. Materials and Methods With IRB approval, we prospectively followed 88 patients to determine the duration of robotic pancreaticoduodenectomy, and the duration of 12 key steps. Each operative step was regressed against the operation date, from most distant to most recent operation date. Data are presented as median (mean ± SD) for illustrative purposes. Results Patients were 73 (71 ± 10.2) years old; 53% were men. Total time patient spent in the operating room was 471 (488 ± 93.3) minutes. Total operative time was 399 (421 ± 90.7) minutes. Total console time was 293 (297 ± 68.0) minutes. The 3 longest portions of the operation were (1) mobilization of the specimen and specimen extraction; (2) construction of the duodenojejunostomy; and (3) closure. Conclusion A third of the operative time is spent off the console. Over half of the steps required more than 20 minutes each to complete. Since robotic operations are associated with shorter LOS and without increased complication rates relative to “open” operations, salutary benefit can be gained by decreasing operative times of robotic procedures. Operative duration is an important metric that needs to be addressed. We need to target the most time-consuming steps, and break them into smaller pieces, to reach optimal efficiency and provide the benefits of decreased operative duration to the patients, hospitals, and providers.
