Colorectal Resections in Patients With Retroperitoneal Sarcoma

COLOSARC-Q is a multicenter study with the objective of providing an up-to-date assessment of colorectal resections and reconstruction techniques in the context of multivisceral resections for retroperitoneal sarcomas, as well as colorectal surgery-associated complications and their impact on patients' quality of life. In multivisceral resections involving the colon and rectum, the primary aim is to achieve complete resection and preserve organ function. However, multivisceral resections have a high risk of perioperative morbidity including anastomotic leakage. The proposed project aims to determine the number of primary anastomoses, their insufficiency rates, and the fraction of patients with primary and secondary stomas. In addition, the patients' quality of life after multivisceral sarcoma resection is to be recorded using standardized surveys. The analysis has the potential to facilitate intraoperative decision-making for colorectal resections in the context of multivisceral resections.
