Abstract:
PurposeIn order to investigate whether colorectal cancer (CRC) patients with endoscopic obstruction benefited from a planned stoma before neoadjuvant chemoradiation (nCRT).MethodsPatients who were diagnosed with CRC with endoscopic obstruction at a single clinical center from January 2017 to April 2022 were retrospectively collected. Baseline characteristics and short-term and long-term outcomes were compared between the stoma group and the no stoma group. Statistical analysis was performed using SPSS (version 22.0) software.ResultsA total of 51 CRC patients with endoscopic obstruction were included in this study. Eleven (21.6%) patients received a planned stoma before nCRT, and 40 (78.4%) patients were treated with immediate nCRT. The mean time from diagnosis to nCRT was 30.6 days for the stoma group and 11.9 days for the no stoma group. There was a significant delay in the initiation of nCRT in the stoma group (P < 0.05). In terms of complications, there was a statistical difference between the stoma group and the no stoma group (P < 0.05). Planned stoma before nCRT did not affect survival for patients with endoscopically obstructing CRC (P > 0.05).ConclusionA planned stoma caused delay in nCRT; the no stoma group was more likely to develop perforation or obstruction of the tumor during nCRT. A comprehensive assessment might be needed to determine whether a planned stoma was necessary in CRC patients with endoscopic obstruction.

Ostomy Care
An ostomy is a surgical procedure that creates an artificial opening from the intestines to the outside of the body, allowing for the rerouting of effluent. This opening is known as a stoma. A stoma usually protrudes above the skin surface, appearing pink or red, moist, and round, and it lacks nerve sensations.
There are different types of ostomies, including colostomies, ileostomies, and urostomies:
Tracheostomy Decannulation
Description of the Procedure
Decannulation refers to the permanent removal of the tracheostomy tube, signaling the resolution of the condition that initially necessitated the tracheostomy. The process requires a well-coordinated interplay between...
