About

Alan Karthikesalingam is a leading researcher in the field of minimally invasive and robotic surgery, with a focus on bariatric and foregut procedures. His major contributions include pioneering systematic reviews and meta-analyses that critically evaluate the efficacy and safety of robotic-assisted surgery compared to traditional laparoscopic techniques. His most cited work, a 2011 pooled analysis of robotic versus laparoscopic Roux-en-Y gastric bypass (114 citations), provided early, evidence-based insights into outcomes for morbidly obese patients, highlighting key differences in operative time and complications. He further advanced the field with a meta-analysis on robotic versus laparoscopic Nissen fundoplication for gastro-oesophageal reflux disease (73 citations), which helped clarify the role of robotics in complex anti-reflux surgery. Beyond clinical outcomes, Karthikesalingam conducted an international survey study (18 citations) that captured global surgeon attitudes toward robotic surgery, offering a unique perspective on adoption barriers and training needs. His work has been instrumental in shaping evidence-based guidelines and informing surgical decision-making, making him a respected voice in the ongoing debate over the value of robotic platforms in general surgery.
