Simultaneous colorectal and hepatic resections for colorectal cancer: postoperative and longterm outcomes

BACKGROUND Our goal was to analyze the results of resection of colorectal cancer and liver metastases in one procedure. STUDY DESIGN Between June 1982 and July 1998, 522 patients underwent liver resection for colorectal metastases. Liver resection was performed simultaneously with colorectal resection in 71 cases, representing the population in this study. Morbidity, mortality, overall survival, and disease-free survival times were analyzed. Median followup time was 29 months (range 6 to 162 months). Prognostic factors and their influence on outcomes were analyzed. RESULTS The median hospital stay was 8 days (range 5 to 23 days). Morbidity was 21% and included nine pleural effusions, seven wound abscesses, four instances of hepatic failure, three systemic infections, three intraabdominal abscesses, and one colonic anastomosis leakage. Operative mortality was 0%. Recurrence rate was 57.7% (41 or 71), and progression of disease was detected in 33.8%. Overall and disease-free survivals at 1, 3, and 5 years were 88%, 45%, and 38% and 67%, 17%, and 9%, respectively. Prognostic factors with notable influence on patient outcomes were nodal stage as per TNM classification, number of liver metastases, diameter (smaller or larger than 5 cm), liver resection specimen weight (lighter or heavier than 90 g), and liver resection margin (smaller or larger than 1 cm). CONCLUSIONS Simultaneous resection of colorectal cancer and liver metastases can be performed with low morbidity and mortality rates, avoiding a second surgical procedure.

Nuevo Metodo de Regeneracion hepatica

Postoperative liver failure (PLF) is the most feared and serious complication after extensive liver resections. We present an innovative surgical technique for the treatment of a patient with colorectal cancer and initially unresectable liver metastases. After completing neoadjuvant chemotherapy, it was decided to perform simultaneous surgery. A left hemicolectomy and cleaning of the metastases in the left liver was performed. As the future liver remnant (FLR) was insufficient, it was decided to perform an in situ liver split and a right portal vein ligation. On the 6(th) day after the surgery a volumetric CT showed an increase greater than 40% of the FLR. The right hepatectomy was completed and the patient was discharged on the 11(th) day after surgery. The technique induced a rapid growth of the FLR, exceeding that reported using portal occlusion. If these findings are corroborated in future studies, this revolutionary technique could enable surgery to be performed in two stages on patients with initially unresectable liver disease during the same hospital admission and without PLF.
