Brief summary in lay language

Data science can help improve the quality of healthcare. However, there are not enough data with high quality. Thus, we need to create a standardized dataset including surgery videos to fill the gap.

Brief summary in scientific language

The Surgical data science (SDS) is a research field that aims to improve the quality of interventional healthcare by observing all aspects of the patient treatment process to provide the right assistance at the right time. To date, most SDS applications are based on the deep learning technique, which has shown great potential to solve challenging tasks in a complex surgical environment. However, such algorithms are dependent on a large amount of training data, which not only must contain data, but also labels (e.g., localization of an instrument in the image), so that they can be used for training. The application of data science in surgery has been far less successful than in other fields of science. An international consortium of experts has identified missing datasets as the major hurdle in enabling SDS. To create high-quality datasets, data needs to be collected according to strict acquisition protocols and annotated by trained personnel following strict annotation protocols. This requires significant effort and the access to expert knowledge represents a major bottleneck. By creating, curating and publishing a dataset for laparoscopic Roux-en-Y gastric bypass, an operation that requires performing intestinal anastomosis, we aim to facilitate the use of SDS methods in training and during operations. The collected data will be two-fold, consisting of (1) data deriving from training sessions and (2) real-life procedures in operating rooms (OR). Care will be taken to systematically capture and annotate perioperative data (Surgical team, skill level, patient data from the Electronic Health Record (EHR)), video clips of surgeons using standardized protocols that will be published together with the dataset. Modern tools will be used for annotation2, and algorithm specific metadata (Implementation, Version, Uncertainty, Training data used, etc.) will be collected and included in the dataset.

Interventions, Observational Groups

Arm 1:
observational study. The surgical phase of gastrojejunostomy is to be recorded and correlation with the outcomes (weight loss and complication such as dumping syndrome) 12 months after surgery will be investigated.

Endpoints

Primary outcome:
outcomes 12 months after surgery including weight loss, complications such aus dumping syndrome
Secondary outcome:
- total weight loss (%TWL) - excess weight loss (%EWL) - quality of life - Sigstad-score - postoperative morbidity
