Abdominal Actinomycotic Abscess after Laparoscopic Sleeve Gastrectomy for Morbid Obesity: A Case Report.

Actinomycosis is a rare, chronic, suppurative, and granulomatous bacterial disease. The species exist as normal flora in the oropharynx, gastrointestinal tract, and the female genital tract. They are incapable of penetrating the normal mucous membranes and become pathogenic only when this barrier has been destroyed by trauma, surgery, immunosuppression, or after viscus perforation.

The Impact of Overweight and Obesity on Reduced-Port Laparoscopic Distal Gastrectomy for Gastric Cancer Patients: A Propensity Score Matching Analysis of a Single-Institution Data.

This study aimed to investigate the short-term postoperative outcomes of reduced-port laparoscopic distal gastrectomy and demonstrate its safety and feasibility in overweight and obese patients with gastric cancer. The medical records of 211 patients who underwent reduced-port laparoscopic distal gastrectomy, between August 2014 and April 2020, were reviewed. After propensity score matching, they were divided into a non-overweight group (n = 68) and overweight group (n = 68).

Transpyloric optic navigation of tumor using a laparoscope during totally laparoscopic distal gastrectomy for gastric cancer.

Purpose: The purpose of this study was to describe the technique of intraoperative transpyloric optic navigation (TPON) and determine its efficacy and feasibility during totally laparoscopic distal gastrectomy (TLDG) in patients with gastric cancer.

Methods: Seventy-nine patients who underwent laparoscopic gastrectomy with transpyloric optic localization of the tumor from January 2016 through December 2018 were enrolled in this study. After resecting the first portion of the duodenum, the distal part of the stomach was exteriorized through an extended supraumbilical trocar site, and a balloon trocar was introduced from the pylorus to determine the location of tumor and determine its resection margin.

Reduced-port laparoscopic distal gastrectomy in obese gastric cancer patients.

Background: Reduced-port laparoscopic gastrectomy is currently widely performed for patients with gastric cancer. However, its safety in obese patients has not yet been verified. This is the first study on reduced-port laparoscopic distal gastrectomy (RpLDG) in obese patients with gastric cancer.

Implementation of Enhanced Recovery after Surgery (ERAS) Program in Perioperative Management of Gastric Cancer Surgery: a Nationwide Survey in Korea.

Purpose: Despite its clinical benefits, enhanced recovery after surgery (ERAS) is less widely implemented for gastric cancer surgery. This nationwide survey investigated the current status of the implementation of ERAS in perioperative care for gastric cancer surgery in South Korea.

Materials And Methods: This survey enrolled 89 gastric surgeons from 52 institutions in South Korea.

Adverse prognostic impact of splenectomy on survival in gastric carcinoma patients: Regression and propensity score matching analysis of 1074 patients.

Backgrounds: Patients with proximal gastric carcinoma undergo total gastrectomy with concomitant splenectomy to ensure the complete removal of splenic hilar lymph nodes. However, the impact of splenectomy on survival remains uncertain. This study aimed to investigate the impact of splenectomy on survival among patients with gastric carcinoma.

Quantitative analysis of promoter methylation in gastric carcinoma.

Purpose: To determine the occurrence of methylation in gastric carcinoma (GC), the status and level of CpG methylation in the promoter region of () were analyzed in early and advanced GCs, as well as in normal gastric tissues.

Methods: The extent of promoter methylation of the gene was assessed quantitatively using pyrosequencing in 60 early and 60 advanced GCs samples harvested upon gastrectomy, and 40 normal gastric mucosa samples from patients with benign gastric diseases as controls.

Results: The methylation frequency for the gene was significantly higher in early than in advanced GCs (40.

Transition from Conventional to Reduced-Port Laparoscopic Gastrectomy to Treat Gastric Carcinoma: a Single Surgeon's Experience from a Small-Volume Center.

Purpose: This study aimed to evaluate the surgical outcomes and investigate the feasibility of reduced-port laparoscopic gastrectomy using learning curve analysis in a small-volume center.

Materials And Methods: We reviewed 269 patients who underwent laparoscopic distal gastrectomy (LDG) for gastric carcinoma between 2012 and 2017. Among them, 159 patients underwent reduced-port laparoscopic gastrectomy.

Surgical Outcomes of Laparoscopic Resection for Subepithelial Lesions on the Gastric Fundus Performed in the Supine or Lateral Decubitus Position.

Background: Laparoscopic resection of gastric subepithelial lesions (SELs) located on the posterior wall of the gastric fundus is technically difficult and time-consuming. To facilitate access, we propose performing the laparoscopic procedure with patients in a right lateral decubitus position, rather than the standard supine position. The aim of our study was to compare operative and clinical outcomes for laparoscopic SEL resection performed in either the right lateral decubitus or the traditional supine position.

Single port intra-gastric full thickness resection: Using "Rotation and Revolution Single Instrument Tie (RRSIT)".

Background/aims: Recently, minimize incisions has led to a reduction in the number of ports, and has led to transumbilical single-port surgery. We evaluated the treatment result of single-port, intragastric, full thickness resections for gastric SMTs. In addition, we introduce a novel intracorporeal knot tying method.

Is Laparoscopy-assisted Radical Gastrectomy Safe in Patients with Child-Pugh Class A Cirrhosis?

Purpose: We investigated early postoperative morbidity and mortality in patients with liver cirrhosis who had undergone radical gastrectomy for gastric cancer.

Materials And Methods: We retrospectively reviewed the medical records of 41 patients who underwent radical gastrectomy at the Chonnam National University Hwasun Hospital (Hwasun-gun, Korea) between August 2004 and June 2009. There were few patients with Child-Pugh class B or C; therefore, we restricted patient selection to those with Child-Pugh class A.
