Study Overview
Brief Summary
This study was a multicenter, retrospective cohort study. Although advancements in surgical techniques have mitigated the incidence of intestinal anastomotic fistula, complete avoidance remains elusive. Anastomotic leakage (AL) complications directly impinge on postoperative quality of life and pose life-threatening risks if inadequately managed. Given AL's adverse prognostic implications and the financial strain on patients' families, identifying its risk factors aids in perioperative risk assessment, enabling timely clinical decisions on interventions to enhance prognosis and curtail adverse outcomes and economic investments.
Detailed Description
Optimal cytoreduction, particularly in advanced cases, significantly extends 5-year survival compared to cases with residual disease exceeding 1 cm. Consequently, ultra-radical tumor cytoreduction procedures, commonly performed in advanced ovarian cancer, entail the excision of abdominopelvic tissues affected by the primary ovarian malignancy, including segments of the bowel, bladder, spleen, gallbladder, diaphragm, and other organs. Rectosigmoid resection (RSR) emerges as the predominant bowel resection, followed by colon and small bowel resections. Intestinal anastomosis post-RSR is indispensable for bowel reconstruction but bears a notable risk of postoperative anastomotic fistula (AL), a major complication. AL incidence rates fluctuate over time, reported between 8-14% in OC surgery patients undergoing RSR.
AL imposes considerable burdens, encompassing elevated hospital costs, prolonged stays, heightened rates of secondary admissions and surgeries, and mortality rates ranging from 3% to 21%. Furthermore, AL delays the commencement of adjuvant chemotherapy, detrimentally impacting overall survival and representing a significant consequence of colorectal surgery.
