Backgrounds/Aims: Despite its limited benefits, operative site drainage after elective hepatectomy is routinely used. This study aimed to investigate the safety and effectiveness of left lateral sectionectomy without operative site drainage. Methods: This study retrospectively collected data from 31 patients who underwent elective left lateral sectionectomy between January 2017 and June 2020. Based on whether operative site drainage was used, the patients were divided into two groups: drainage and non-drainage of the operative site and a comparative analysis was conducted. Results: A total of 31 patients underwent left lateral sectionectomy during the study period. Of these, 22 patients were diagnosed with hepatocellular carcinoma; three, with intrahepatic cholangiocarcinoma; three, with liver metastasis; and three, with benign liver disease. Ten patients underwent laparoscopy. No significant differences were observed between the open and laparoscopic surgery groups. In the univariate analysis, there were no significant differences in the pre-, intra-, and postoperative clinicopathological factors between the non-drainage and drainage groups. The hospitalization period in the non-drainage group was significantly shorter than in the drainage group (8.44 days vs. 5.87 days, p < 0.05). In the operative site drainage non-use group, there were no cases of intraperitoneal fluid collection requiring additional procedures. Conclusions: Routine use of surgical drainage for left lateral sectionectomy of the liver to prevent intraperitoneal fluid collection is unnecessary.

Backgrounds/Aims: Anatomical resection has superior oncologic outcomes over non-anatomical resection in hepatocellular carcinoma, and left lateral sectionectomy is the simplest and easiest perform anatomical resection procedure among liver resections. The purpose of this study was to find out the safety and feasibility of pure laparoscopic left lateral sectionectomy (PLLLS) for hepatocellular carcinoma. Methods: Patients who underwent left lateral sectionectomy at a tertiary referral hospital, from August 2007 to April 2019 were enrolled in this retrospective study. After matching the 1 : 3 propensity score, 17 open and 51 pure laparoscopic cases were selected out of 102 cases of total left lateral resection for hepatocellular carcinoma. The group was analyzed in terms of patient demographics, preoperative data, and postoperative outcomes. Results: During the study period, there was no open conversion case. The mean operative time and complication were not statistically significant different between the two groups. There was no statistically significant difference in disease-free survival and overall survival had no statistical between the two groups. There were no mortality cases, and postoperative hospital stay was significantly shorter in the PLLLS group than in the open left lateral sectionectomy (OLLS) group. Conclusions: The oncologic outcomes and complication rate were the same in the PLLLS and OLLS groups. However, the hospital stay was shorter in the PLLLS group than in the OLLS group. The present study findings demonstrate that the PLLLS is a safe and feasible procedure for hepatocellular carcinoma.

Ascaris lumbricoides causes one of the most common soil-transmitted helminthiases globally. The worms mostly infect the human small intestine and elicit negligible or nonspecific symptoms, but there are reports of extraintestinal ectopic ascariasis. We describe a rare case of biliary ascariasis mistaken for biliary stent in a 72-year-old female patient with a history of liver resection. She visited our outpatient clinic complaining of right upper quadrant pain and fever for the past week. She had previously undergone left lateral sectionectomy for recurrent biliary and intrahepatic duct stones 2 years ago. Besides mildly elevated gamma-glutamyl transferase levels, her liver function tests were normal. Magnetic resonance cholangiopancreatography revealed a linear filling defect closely resembling an internal stent from the common bile duct to the right intrahepatic bile duct. A live female A. lumbricoides adult worm was removed by endoscopic retrograde cholangiopancreatography (ERCP). Despite a significant decrease of the ascariasis prevalence in Korea, cases of biliary ascariasis are still occasionally reported. In this study, a additional case of biliary ascariasis, which was radiologically misdiagnosed as the biliary stent, was described in a hepatic resection patient by the worm recovery with ERCP in Korea.
