Predictors of major postoperative complications in cytoreductive surgery with or without hyperthermic intraperitoneal chemotherapy.

PURPOSE: Cytoreductive Surgery (CRS) ± Hyperthermic Intraperitoneal Chemotherapy (HIPEC) is associated with a high incidence of postoperative morbidity. Our aim was to identify independent, potentially actionable perioperative predictors of major complications. METHODS: We reviewed patients who underwent CRS ± HIPEC from June 2020 to January 2022 at a high-volume center. Postoperative complications were categorized using the Comprehensive Complication Index, with the upper quartile defining major complications. Multivariate logistic analysis identified predictive and protective factors. RESULTS: Of 168 patients, 119 (70.8%) underwent HIPEC. Mean Comprehensive Complication Index was 12.6 (12.7) and upper quartile cut-off was 22.6. Medical complications were more frequent but less severe than surgical (63% vs 18%). Forty-six patients (27.4%) comprised the "major complications" group (mean CCI 30.1 vs 6.3). Multivariate logistic regression showed that heart disease (RR 1.9; 95% CI: 1.1 to 3.3), number of anastomoses (RR 2.4; 95% CI:1.3 to 4.6) and first 24-h fluid balance (RR 1.1; 95% CI: 1.1 to 1.2), were independently associated as risk factors for major complications, while opioid-free anesthesia (RR 0.6; 95% CI: 0.3 to 0.9) and high preoperative hemoglobin (RR 0.9; CI 95%: 0.9 to 0.9) were independent-protective factors. CONCLUSION: Preoperative heart diseases, number of anastomoses and first 24 h-fluid balance are independent risk factors for major postoperative complications, while high preoperative hemoglobin and opioid-free anesthesia are protective. Correction of anemia prior to surgery, avoiding positive fluid balance and incorporation of opioid-free anesthesia strategy are potential actionable measures to reduce postoperative morbidity.

Pseudomixoma peritoneal: primeros casos tratados en Colombia con peritonectomía radical y quimioterapia intraperitoneal hipertérmica / Pseudomyxoma peritonei: first cases treated by radical cytoreductive surgery and hyperthermic intraperitoneal chemotherapy

El pseudomixoma peritoneal es una enfermedad infrecuente caracterizada por ascitis mucinosa acompañada de implantes tumorales peritoneales y sobre el epiplón. La etiología de esta entidad es desconocida y, según la histología, se divide en dos grandes grupos: la adenomucinosis y la carcinomatosis mucinosa peritoneal.Tradicionalmente, el tratamiento quirúrgico recomendado es la citorreducción parcial que se repite regularmente para controlar los síntomas hasta que no se encuentre ningún beneficio adicional. A pesar de la controversia, en la actualidad, la evidencia favorece la realización de la peritonectomía radical más quimioterapia intraperitoneal hipertérmica, seguidas de quimioterapia intraperitoneal posoperatoria temprana (en los 7 días siguientes al procedimiento).A continuación se presentan los dos primeros casos tratados con esta técnica en Colombia y se revisa detalladamente la información publicada al respecto.
