Abstract
Background: Evidence of superiority of robotic-assisted surgery for colorectal resections remains limited. This systematic review and meta-analysis aims to compare robotic-assisted and laparoscopic surgical techniques in high-risk patients undergoing resections for colorectal cancer.
Methods: Systematic searches were performed using Pubmed, Embase and Cochrane library databases from inception until December 2024. Randomised and non-randomised studies reporting outcomes of robotic-assisted or laparoscopic resections in the following high-risk categories were included: obesity, male gender, the elderly, low rectal cancer, neoadjuvant chemoradiotherapy and previous abdominal surgery. Comparative meta-analyses for all sufficiently reported outcomes were completed. Risk of bias was assessed using the ROBINS-I and RoB 2 tools for non-randomised and randomised studies, respectively.
Results: 48 studies, including a total of 34,846 patients were eligible for inclusion and 32 studies were utilised in the comparative meta-analyses. Conversion to open rates were significantly lower for robotic-assisted surgery in patients with obesity, male patients and patients with low rectal tumours (obese OR 0.41 [CI 0.32-0.51], p < 0.00001); male gender (OR 0.28 [CI 0.22-0.34], p < 0.00001); low tumours OR 0.10 [CI 0.02-0.58], p = 0.01). Length of stay was significantly reduced for robotic-assisted surgery in patients with obesity (SMD 0.25 [CI - 0.41 to - 0.09], p = 0.002). Operative time was significantly longer in all subgroups (obesity SMD 0.57 [CI 0.31-0.83], p < 0.0001; male gender SMD 0.77 [CI 0.17-1.37], p = 0.01; elderly SMD 0.50 [CI 0.18-0.83], p = 0.002; low rectal tumours SMD 0.48 [CI 0.12-0.84], p = 0.008; neoadjuvant chemoradiotherapy SMD 0.72 [CI 0.34-1.09], p = 0.0002; previous surgery SMD 1.55 [CI 0.05-3.06], p = 0.04). When calculable, blood loss, length of stay, complication rate and lymph node yield were comparable in all subgroups.
Conclusions: This review provides further evidence of non-inferiority of robotic-assisted surgery for colorectal cancer and demonstrates conversion rates are superior in specific, technically challenging operations.
期刊介绍：
Techniques in Coloproctology is an international journal fully devoted to diagnostic and operative procedures carried out in the management of colorectal diseases. Imaging, clinical physiology, laparoscopy, open abdominal surgery and proctoperineology are the main topics covered by the journal. Reviews, original articles, technical notes and short communications with many detailed illustrations render this publication indispensable for coloproctologists and related specialists. Both surgeons and gastroenterologists are represented on the distinguished Editorial Board, together with pathologists, radiologists and basic scientists from all over the world. The journal is strongly recommended to those who wish to be updated on recent developments in the field, and improve the standards of their work.
Manuscripts submitted for publication must contain a statement to the effect that all human studies have been reviewed by the appropriate ethics committee and have therefore been performed in accordance with the ethical standards laid down in an appropriate version of the 1965 Declaration of Helsinki. It should also be stated clearly in the text that all persons gave their informed consent prior to their inclusion in the study. Details that might disclose the identity of the subjects under study should be omitted. Reports of animal experiments must state that the Principles of Laboratory Animal Care (NIH publication no. 86-23 revised 1985) were followed as were applicable national laws (e.g. the current version of the German Law on the Protection of Animals). The Editor-in-Chief reserves the right to reject manuscripts that do not comply with the above-mentioned requirements. Authors will be held responsible for false statements or for failure to fulfill such requirements.
