Endoscopic Submucosal Dissection of Large Recto-sigmoid Lesions Under Spinal Anesthesia

Colorectal (Colon or Rectal) Cancer Clinical Trial

Official title: Endoscopic Submucosal Dissection of Large Recto-sigmoid Lesions Under Spinal Anesthesia

Status Completed

Clinical Trial Summary

The investigators collected data on all consecutive patients who underwent ESD for recto-sigmoid laterally spreading tumors (LSTs) >35 mm under SA between January 2021 and March 2024. The investigators evaluated the technical success and safety of SA in terms of ARAEs, and pain, measured via visual assessment scale (VAS).

Clinical Trial Description

Background and study aim: Endoscopic submucosal dissection (ESD) of large colorectal lesions requires the patient to be in a still position for a long time. Both deep sedation and general anesthesia carry a substantial risk of anesthesia-related adverse events (ARAEs), especially in frail patients. Conversely, mild-to-moderate sedation does not prevent involuntary movements of the patient. Spinal anesthesia (SA) is a safe and simple technique that provides analgesia and motor block without systemic drug administration or orotracheal intubation. As the use of SA in colorectal endoscopic resections has not been described so far, we aimed to evaluate the feasibility and performance of SA in large (>35 mm) recto-sigmoid lesion ESD.

Patients and methods: The investigators collected data on all consecutive patients who underwent ESD for recto-sigmoid laterally spreading tumors (LSTs) >35 mm under SA between January 2021 and March 2024. The investigators evaluated the technical success and safety of SA in terms of ARAEs, and pain, measured via visual assessment scale (VAS). The secondary endpoints were as follows: intra- and post-procedural need for additional opioid or other analgesic drug administration, ESD-related adverse eventss, length of hospital stay, and median ESD duration. ;
