RESUMO
Post hepatectomy Liver Failure (PHLF) is a fatal complication, especially after major liver resection. Insufficient remnant liver volume is a common cause of postoperative liver failure. Many strategies have been applied to induce the remnant liver hypertrophy: Portal vein embolization (PVE), PVE combined with hepatic vein embolization (LVD), two staged liver resection, Associated liver partition with portal vein ligation for staged hepatectomy (ALPPS). We present a case of a 39-year-old male patient who underwent LVD for preoperative liver hypertrophy. After LVD, the patient underwent additional artery embolization, and the patient's remaining liver volume increased by 63.2% in 7 weeks. The patient underwent a right hepatectomy and was discharged after 10 days, with no complications of postoperative liver failure. Simultaneous portal and hepatic vein embolization is a technique that has been applied recently because it can significantly promote the speed and extent of liver hypertrophy before major liver resection compared to portal vein embolization procedure alone. In this case, additional hepatic artery embolization may be an important factor lead to hypertrophy of the remnant liver, thereby shortening the waiting time for surgery and reducing the risk of tumor progression. Liver venous deprivation is safe and feasible to perform. Additional hepatic artery embolization may accelerate the hypertrophy of the remnant liver.
RESUMO
Backgrounds/aims: To evaluate the outcomes of hepatocellular carcinoma (HCC) patients who underwent right anatomical hepatectomy using the combination of the extrahepatic Glissonean pedicle approach (Takasaki's technique) and liver hanging maneuver (LHM) (Belghiti's technique). Patients and methods: A retrospective analysis of 30 cases of HCC treated with right hepatectomy using extrahepatic Glissonean pedicle approach and LHM by only one surgeon at our department from March 2020 to August 2023. Clinical characteristics, pathological results, postoperative outcomes, and survival rate were analyzed. Results: Among the 30 HCC patients analyzed, males accounted for 96.7% of patients. The mean age was 54.9±11 years. 96.7% had normal preoperative liver function (Child-Pugh A). LHM with an extrahepatic Glissonean approach was feasible in 100% of cases with minor blood loss, no blood transfusion, intraoperative complications, or perioperative mortality. The mean operative time was 123.8±29.0 min. The mean hospital stay was 9.37±4.02 days. Postoperative liver failure accounted for 6.7%. Pathological results: 63.3% moderately differentiated HCC; 36.7% poorly differentiated HCC. 1-year, 2-year, and 3-year survival rates were 86.1, 73.8, and 59.0%, respectively. Recurrence was witnessed in 13 (43.3%) cases, with 6 (20%) cases in remnant liver. 1-year, 2-year, and 3-year disease-free survival were 69.3, 42.0, and 28.0%, respectively. Conclusion: Right anatomical hepatectomy using extrahepatic Glissonean pedicle approach combined LHM for HCC was feasible and safe at our high-volume oncology center in a developing country.
