Abstract

Dissection of the mesoappendix from the appendix is a crucial step in laparoscopic appendicectomies. Variation in the position of the mesoappendix during this common operation has not been previously described. We propose a classification system for the mesoappendix position seen laparoscopically and evaluate the impact each position has on operative difficulty and surgical approach. The mesoappendix positions in laparoscopic appendicectomies between January 2023 and January 2024 were classified into four categories from M1 to M4. Patients were grouped according to their mesoappendix positions. Outcomes evaluated included operative time, need for additional ports, use of energy devices, deviations from standard operative approach. Various mesoappendix positions were correlated with the intra-operative appendix position and histopathological findings. 104 laparoscopic appendicectomy cases were reviewed. 30 were classified as M1, 31 as M2, 27 as M3, and 16 as M4. Mean operative time was significantly longer for cases where the mesoappendix was in the M3 position (p > 0.001). This position was also more likely to require an additional port and deviate from the standard operative approach including need for retrograde dissection and staple cecectomy. We introduce a potentially surgical important classification system of the mesoappendix in laparoscopic appendicectomies. In this study, we attempt to validate the differences each position has on operative approaches and outcomes. We found that the M3 position is of greater difficulty to approach when dissecting the mesoappendix. This classification may serve as a valuable tool in guiding intra-operative surgical decision-making.

期刊介绍: Updates in Surgery (UPIS) has been founded in 2010 as the official journal of the Italian Society of Surgery. It’s an international, English-language, peer-reviewed journal dedicated to the surgical sciences. Its main goal is to offer a valuable update on the most recent developments of those surgical techniques that are rapidly evolving, forcing the community of surgeons to a rigorous debate and a continuous refinement of standards of care. In this respect position papers on the mostly debated surgical approaches and accreditation criteria have been published and are welcome for the future. Beside its focus on general surgery, the journal draws particular attention to cutting edge topics and emerging surgical fields that are publishing in monothematic issues guest edited by well-known experts. Updates in Surgery has been considering various types of papers: editorials, comprehensive reviews, original studies and technical notes related to specific surgical procedures and techniques on liver, colorectal, gastric, pancreatic, robotic and bariatric surgery.
