ABSTRACT
BACKGROUND:
Cytoreductive surgery (CCRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) improves the overall survival in selected cases of peritoneal carcinomatosis (PC) of colorectal origin. Second-look surgery in asymptomatic patients at high risk of developing PC has shown encouraging results. This study aims at identifying cases in which initial anastomosis should be resected.METHODS:
Patients treated by second-look surgery and HIPEC were identified from a prospective database. High-risk was defined as synchronous resected and minimal PC, ovarian metastasis or perforated primary tumor. Patients were divided in two groups based on intra-operative evaluation of the anastomosis possibly-invaded (PI) and unlikely-invaded (UI). PI was defined as 1) PC away from the anastomosis, 2) nodules resting on the anastomosis 3) anastomotic stenosis or anastomotic thickening. Anastomosis in the PI group were resected.RESULTS:
Forty patients were included 12 in the PI group and 28 in the UI group. Incidence of pathological anastomotic invasion was 42% (5 on 12 patients) in the PI group. In the UI group, 2 patients had anastomotic recurrence, both associated with peritoneal recurrence. Morbidity and mortality was not influenced by anastomosis resection. The presence of suspicious nodules on the anastomosis had a sensitivity of 100% and a specificity of 89% in predicting anastomotic invasion.CONCLUSION:
In second-look surgery and HIPEC for colorectal cancer at high-risk of PC, anastomosis should be resected when overlying PC nodules are found. This attitude is supported by high sensitivity of this finding for anastomotic invasion and low morbidity related to anastomotic resection.Palavras-chave
