Out-of-Hours Laparoscopic Appendectomy: A Risk Factor for Postoperative Complications in Acute Appendicitis?

The surgical environment can influence the clinical outcomes of procedures and patient conditions. This retrospective study aimed to evaluate how surgical timing affects short-term outcomes in emergency laparoscopic appendectomy for acute appendicitis. A total of 647 patients with acute appendicitis who underwent emergency laparoscopic appendectomy at Chuncheon Sacred Heart Hospital between January 2018 and June 2021 were included in this study.

Hepatitis B Virus DNA-Level Change is Associated With Tumor Recurrence in Patients With Resected Hepatitis B Virus Hepatocellular Carcinoma.

Introduction: To investigate the significance of perioperative hepatitis B virus (HBV) DNA changes for predicting recurrence in patients with HBV-related hepatocellular carcinoma (HCC) undergoing liver resection (LR).

Methods: From 2013 to 2020, 241 patients with HBV-related HCC who underwent LR in five Hallym university-affiliated hospitals were enrolled. The serum HBV DNA level, together with other clinicopathological variables, was analyzed for association with HCC recurrence.

Impact of the COVID-19 pandemic on the outcomes of laparoscopic appendectomy for acute appendicitis.

Purpose: This retrospective study aimed to evaluate the impact of the coronavirus disease 2019 (COVID-19) pandemic on the time interval from symptom onset to surgery and on the operative outcomes of laparoscopic appendectomy for patients with acute appendicitis.

Methods: Between October 2018 and July 2021, laparoscopic appendectomy was performed in 502 patients with acute appendicitis admitted to Hallym University Chuncheon Sacred Heart Hospital in Chuncheon, Korea. We compared demographic data, serum levels of inflammatory markers, time to event of appendicitis, and operative outcomes between the pre-COVID-19 and post-COVID-19 pandemic groups.

Sarcopenia with systemic inflammation can predict survival in patients with hepatocellular carcinoma undergoing curative resection.

Background: This study aimed to examine the prognostic significance of sarcopenia combined with systemic inflammation in patients who underwent curative hepatectomy for hepatocellular carcinoma (HCC).

Methods: Between January 2010 and July 2019, we identified 159 patients with HCC who underwent curative hepatectomy at three institutional centers. We retrospectively analyzed clinicopathological outcomes, surgical outcomes, platelet lymphocyte ratio (PLR) as a systemic inflammatory marker, and computed tomography (CT)-assessed sarcopenia at the third lumbar vertebra level (L3).

Hybrid Appendectomy in Pediatric Appendicitis: A Comparative Analysis of Single-Port and Multiport Laparoscopic Appendectomy.

Hybrid appendectomy (HA) has the technical advantages of the excellent visual field provided by laparoscopic surgery and is fast and easy similar to open surgery. We aimed to compare the safety and effectiveness of HA with single- and multiport laparoscopic appendectomy (SPLA and MPLA) in pediatric patients with acute appendicitis. This retrospective study compared the short-term operative outcomes between HA, SPLA, and MPLA groups.

Learning Curve in Laparoscopic Pancreaticoduodenectomy: Using Risk-Adjusted Cumulative Summation Methods.

Laparoscopic pancreaticoduodenectomy (LPD) is one of the most technically challenging operations of minimally invasive surgery. We aimed to analyze the learning curve of a single surgeon who conducted 115 LPDs at a single center. From August 2015 to August 2020, 115 patients underwent LPD.

Outcomes of laparoscopic common bile duct exploration (LCBDE) after failed endoscopic retrograde cholangiopancreatography versus primary LCBDE for managing cholecystocholedocholithiasis.

Objective: This study was performed to compare the outcomes of laparoscopic common bile duct exploration (LCBDE) after failed endoscopic retrograde cholangiopancreatography (ERCP) versus primary LCBDE for managing cholecystocholedocholithiasis.

Methods: We retrospectively analyzed data from 59 patients who underwent LCBDE during laparoscopic cholecystectomy (LC) for managing cholecystocholedocholithiasis from January 2013 to August 2019. The patients underwent either primary LCBDE plus LC (Group I) or LCBDE plus LC after failed ERCP (Group II).

Laparoscopic versus open pancreaticoduodenectomy for pancreatic neuroendocrine tumors: a single-center experience.

Background: The efficacy and outcomes of laparoscopic resection for pancreatic neuroendocrine tumors (PNETs) are well established; however, specific data regarding the outcomes of laparoscopic pancreaticoduodenectomy (L-PD) are limited. The purpose of the present study was to compare the clinical and oncological outcomes following L-PD versus open PD (O-PD) in patients with PNETs.

Methods: This retrospective study included 149 patients with PNETs who underwent PD at the Asan Medical Center between January 2006 and December 2017.

Time-trend and recurrence analysis of pancreatic neuroendocrine tumors.

This study aimed to evaluate the evolving trends in clinicopathological features of pancreatic neuroendocrine tumors and to analyze the predictors of recurrence after curative resection. Data collected retrospectively from a single center between January 1990 and December 2017 were analyzed. Patients were categorized chronologically into three groups for evolving time-trend analysis.

The 100 most influential manuscripts on hepatocellular carcinoma: a bibliometric analysis.

Objective: Citation analysis represents one of the best available methods to identify the most influential articles. This study aimed to identify and characterize the top 100 highly cited articles (T100) that focus on hepatocellular carcinoma and to reveal the trends in accomplishments within this field.

Methods: A search of the Thomson Reuters Web of Science citation indexing database was conducted using terms related to hepatocellular carcinoma.

A single-center experience with the laparoscopic Warshaw technique in 122 consecutive patients.

Background: Preservation of the spleen in distal pancreatectomy has recently attracted considerable attention. Our current study aimed in the first instance to define the safety of lap-WT in relation to the capacity of this technique to achieve preservation of the spleen and secondly to investigate the effectiveness of a planned lap-WT procedure or early conversion to lap-WT in selected patients with a large tumor attached to the splenic vessels.

Methods: Among 1056 patients who underwent a laparoscopic distal pancreatectomy between January 2005 and December 2014 at our hospital, 122 (24.
