Error rating tool to identify and analyse technical errors and events in laparoscopic surgery

Abstract

The proposed error rating tool allows an objective and reliable assessment of operative performance in laparoscopic gastric bypass procedures.

The Generic Error Rating Tool: A Novel Approach to Assessment of Performance and Surgical Education in Gynecologic Laparoscopy

“…12 Each of these generic task groups is subdivided into 4 distinct error modes: (1) too much use of force or distance, (2) too little use of force or distance, (3) inadequate visualization, and (4) wrong orientation of instrument. 12 Technical errors and resulting events are marked in the GERT checklist (e-component) under the adequate surgical task group and error mode, according to the time they appear in the video material (time stamped). Every error is counted irrespective of perceived seriousness or the absence or presence of sequelae (e.g., bleeding and tissue damage).…”

“…Therefore, there may also be a benefit in assessing technical surgical errors and injury mechanisms. 12 Studies investigating technical errors in laparoscopy are limited, and widespread implementation of error analysis as an educational tool or as a method of quality control is lacking. [13][14][15] Recently, a new framework has been developed that was designed to measure technical errors during laparoscopy.…”

“…The Generic Error Rating Tool (GERT) has been trialed in the context of laparoscopic Roux-en-Y gastric bypass procedures, satisfying multiple sources of validity. 12 The tool is intuitive to use and deemed applicable to any laparoscopic procedure. In contrast to global skill rating frameworks, analysis with the GERT assesses every technical error that occurs during a laparoscopic procedure and therefore allows an in-depth analysis of the surgeon's specific skills and respective weaknesses.…”

Video retrieval in laparoscopic video recordings with dynamic content descriptors

“…While many works have been proposed for the first two categories mentioned above, content similarity search for supporting surgical quality assessment has been addressed only sparsely in the literature so far. De facto standards for objective assessment methods are just starting to establish [10,22], and related research in this medical field is a niche area. However, it has been shown in recent work that manual post-hoc analysis of video recordings of laparoscopic surgeries can adequately categorize surgeons according to skill and training level.…”

“…The reasons behind are manifold -among some other motivations the videos are used for: (1) teaching purposes; e.g., to train surgery techniques with inexperienced surgeons, (2) post-operative explanations to the patients, (3) detailed visual information for follow-up surgeries, and (4) evidence in case of lawsuits from patients [34,43]. Another, more recently emerged purpose for usage of the recorded endoscopic video footage is surgical quality assessment (SQA) [10,22]. Through the recorded video the surgery can be revisited, the surgeon's level of skill can be assessed, and the video can be thoroughly checked for the occurrence of technical errors, which is especially important in medical endoscopy.…”
