Predictors of Rescue Surgery, Mortality, and Permanent Stoma After Anastomotic Leak Following Colorectal Cancer Resection

Anastomotic leakage is a serious complication following colorectal cancer resection and may result in emergency reoperation, severe sepsis, death, loss of the colorectal anastomosis, and formation of a long-term or permanent intestinal stoma. This multicentre observational cohort study will investigate patients who develop an anastomotic leak following colorectal cancer resection with primary anastomosis. The study will evaluate patient-related, tumour-related, operative, biochemical, radiological, leak-related, and treatment-related factors associated with three major outcomes: unplanned rescue surgery, 90-day mortality, and permanent stoma formation. No treatment will be assigned by the investigators. Diagnosis and management of anastomotic leakage will be determined by the treating surgical teams according to their usual clinical practice. Participants will be followed for at least 12 months after the index colorectal resection. The results may help clinicians identify high-risk patients, improve the timing of intervention and source control, support discussions with patients and families, and develop future risk-prediction models for anastomotic leak outcomes.

Effect of a Mobile Application on Stoma Adaptation and Quality of Life

This single-blind, parallel-group randomized controlled trial aims to evaluate the effects of a mobile app-based education, counseling, and follow-up program on stoma adaptation and quality of life in adults with a newly ostomy. The study will be conducted at the Stomatherapy Unit of Gazi University Health Research and Application Center (Ankara, Turkey). Participants meeting the inclusion criteria (n=66) will be assigned to intervention (mobile app support + standard care) and control (standard care only) groups in a 1:1 ratio via block randomization; participants will be kept unaware of their group assignment. Participants in the intervention group will download the "Stomatherapy-M" app on the day of discharge and will access structured educational content, receive nurse counseling (messaging and scheduled video calls), and share scheduled follow-up records regularly for six months. Follow-up frequency will be weekly in the first month, biweekly in the second month, and monthly in the following months. Primary outcomes; Adaptation to the stoma (Ostomy Adjustment Inventory) and stoma-related quality of life (Quality of Life Adaptation Scale) assessed at 15 days and 1, 3, and 6 months after discharge. App usability (MAUS) will be measured at 6 months only in the intervention group.
