This study aims to provide qualitative evidence on the barriers and facilitators influencing the choice between laparoscopic cholecystectomy (LC) and robotic cholecystectomy (RC) among the involved stakeholders and healthcare professionals.

The purpose of this study is to compare the environmental and clinical impacts of elective robotic cholecystectomy (RC) and laparoscopic cholecystectomy (LC) for benign disease.

The objectives of this study are to assess the safety and durability of combined hybrid APC and ESG compared to traditional ESG, and to assess weight loss and improvement in obesity-related co-morbidities in combined hybrid APC and ESG compared to ESG alone.

The purpose of this study is to compare treatment effectiveness and safety between Transoral Incisionless Fundoplication (TIF) and Laparoscopic Nissen Fundoplication (LNF) in GERD patients with hiatal hernia undergoing hernia repair.

The purpose of this study is to identify a predictive model for worsening of preexisting gastroesophageal reflux disease (GERD) or development of de novo GERD after laparoscopic sleeve gastrectomy (LSG) by using EndoFLIP, upper endoscopy and esophageal manometry to assess patients preoperatively in a discovery cohort.  This prospective predictive model will then identify sensitivity, specificity, positive and negative predictive values for prediction of worsening or de novo GERD.
