Brief summary

Objective: Investigators aimed to evaluate the impact of a high resolution standardized laparoscopic (HRSL) cholecystectomy protocol on operative time and intraoperative interruptions in a teaching hospital. Background: Interruptions of the surgical workflow or microcomplications (MC) lead to prolonged procedure times and costs and can be indicative for surgical mistakes. Reducing MC can improve operating room efficiency and prevent intraoperative complications. Methods: Audio video records of laparoscopic cholecystectomies were reviewed regarding type, frequency and duration of MC before and after the implementation of a HRSL which included the introduction of a stepwise protocol for the procedure and a teaching video. After consent operating team members were obliged to prepare the operation with these resources.

Design outcomes

Primary

Measure	Time frame	Description
median hourly delay due to microcomplications	Any microcomplications are recorded between skin incision to skin closure during laparoscopic cholecysectomy	median hourly increase in operative time in seconds due to microcomplications before and after an intervention to reduce microcomplications. Microcomplications are defined as any interruption of the surgical workflow.
