Standardisation in Robotic Surgery for Inflammatory Bowel Disease: A Systematic Review

Background Robotic-assisted surgery offers technical advantages over laparoscopy, including improved dexterity and visualisation. However, its role in inflammatory bowel disease (IBD) remains poorly defined, with existing studies limited by variability and lack of standardisation. This systematic review aimed to evaluate the reproducibility, operative detail, outcome reporting, and procedural consistency in the current literature on robotic-assisted surgery for IBD. Methods A systematic review was conducted following PRISMA 2020 guidelines and registered on PROSPERO (CRD42024514488). Comprehensive searches of five databases and grey literature from January 2015 to April 2024 were performed. Studies involving robotic surgery in adult IBD patients were included. Methodological quality was assessed using the Newcastle–Ottawa Scale. Results Sixteen studies involving 614 patients met inclusion criteria. Most were retrospective (81.3%) and single-arm (62.5%), with robotic ileocolic resection being the most common procedure (50%). Significant heterogeneity existed in port placement, docking, and intraoperative techniques. Technical reporting, particularly on robotic setup, was inconsistent. Definitions of postoperative outcomes, including complications and conversion rates, varied across studies. Enhanced Recovery After Surgery protocols were used in 18.8% of studies, with minimal reporting of patient-reported outcomes. While risk of bias was generally low, limited follow-up and absence of comparator arms reduced the strength of conclusions. Conclusions Current evidence on robotic surgery in Crohn’s disease is methodologically variable and poorly standardised, particularly regarding technical setup and outcome definitions. Future research should focus on prospective, multicentre studies with detailed intraoperative data, standardised outcomes, and long-term follow-up.
