Clinical Studies

Identifying Factors Influencing Surgical Choice Of Laparoscopic Vs Robotic Cholecystectomy Through Patient Interviews Rochester, MN
This study aims to provide qualitative evidence on the factors influencing the choice between laparoscopic cholecystectomy (LC) and robotic cholecystectomy (RC) among patients. The primary objective of this study is to identify key factors that influence patients’ choice between LC and RC through qualitative interviews.

Reducing Emissions Of Robotic Surgical Approaches Through Transdisciplinary Studies – Life Cycle Assessment Rochester, MN
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.

Hybrid Argon Plasma Coagulation and Endoscopic Sleeve Gastroplasty Trial (HAPCET): A Single-center Randomized Controlled Trial (HAPCET) Rochester, MN
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.
Prediction of Post-laparoscopic Sleeve Gastrectomy Gastroesophageal Reflux Disease with an Endolumenal Functional Lumen Imaging Probe (EndoFLIP) Rochester, MN
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.
