[Laparoscopic Liver Resection for the Elderly Hepatocellular Carcinoma Patients-A Single Institutional Experience].

INTRODUCTION

Laparoscopic liver resection(LLR)has been reported as a safe, minimally invasive, and effective approach to the management of liver tumor. The aim of this study was to analyze the perioperative results and outcomes of LLR for the elderly hepatocellular carcinoma(HCC)patients and to compare to the non-elderly HCC patients.

PATIENTS AND METHOD

Between May 2010 and November 2021, 725 patients(HCC 407, CRC Mets 171, others 147)patients underwent LLR at Kansai Rosai Hospital. 407 patients who underwent LLR for HCC were divided into 2 groups those who were over 80 years old(n=67)and under 79 years old(n=340). The patient age was 82.7 and 68.8 years, while the male to female ratio was 41/26 and 238/102 in the elderly and non-elderly groups, respectively. According to the liver cancer study group of Japan, the pathological Stage 0/Ⅰ/Ⅱ/Ⅲ/Ⅳ was 23/34/8/2 and 117/146/57/20 patients(p=0.1086)in the elderly and non- elderly groups, respectively. This study was approved by the Human Ethics Review Committee of Kansai Rosai Hospital(Certificate Number: 2101006).

RESULTS

The elderly group had an average operation time of 316.1 minutes, an estimated blood loss of 277.3 g, and a hospital stay of 14.3 days. The non-elderly group had an average operation time of 347.2 minutes, an estimated blood loss of 233.7 g, and a hospital stay of 12.9 days. No significant differences were noted between the elderly patients and the non-elderly patients with respect to the rate of procedure, operation time, intraoperative blood loss, hospital stay, morbidity, and postoperative laboratory data.

CONCLUSION

The LLR was undergone in safety, even for the over 80 years old patients. The results of LLR for HCC over 80 years old were comparable both in short-term results with under 79 years old group. It was considered that the minimally invasiveness of LLR allows comparable surgical treatment for the elderly with non-eldery.
