Topic: Recent Advances in Gastrointestinal Tumour and Bariatric-Metabolic Surgery

Introduction

Minimally invasive techniques have transformed gastrointestinal tumour and bariatric surgery by enabling faster recovery, reducing complications, and improving long-term outcomes. With the rising prevalence of GI tumour- and obesity-related diseases, ongoing surgical optimisation and innovation are essential. Recent progress in laparoscopic, robotic, and endoscopic technologies, along with the adoption of approaches such as fluoroscopic imaging, single-port surgery, and natural orifice transluminal endoscopic surgery, is expanding clinical applications. Metabolic surgery for weight management is also evolving, incorporating minimally invasive approaches such as uniportal surgery, hiatal hernia repair, and gastric diversion stenting. A growing body of evidence supports the effectiveness of these interventions in mitigating obesity-related complications. This Special Issue highlights recent innovations in gastrointestinal oncology and bariatric-metabolic surgery, aiming to shed light on the future direction in minimally invasive practice.
