Purpose: This trial (KLASS-12) compares the efficacy and safety of reduced-port laparoscopic gastrectomy (RPLG) versus conventional 5-port laparoscopic gastrectomy (CPLG) for early gastric cancer (EGC).

Materials And Methods: This multicenter, open-label, randomized controlled trial enrolled patients diagnosed with gastric adenocarcinoma (T1N0M0) at 15 university hospitals in Korea. Participants underwent RPLG or CPLG with at least D1+ lymph node dissection.

Comparison of treatment strategies for submucosal tumors originating from the muscularis propria at esophagogastric junction or cardia.

Background: The spectrum of gastric submucosal tumors (SMTs) in the upper gastrointestinal system ranges from non-neoplastic to malignant lesions, with gastrointestinal stromal tumors exhibiting inherent malignant potential. However, the diagnosis of SMTs remains challenging, and treatment methods, especially for tumors located at the cardia or esophagogastric junction (EGJ), are not well established. Minimally invasive techniques - such as endoscopic submucosal dissection (ESD), submucosal tunneling endoscopic resection (STER), and laparoscopic wedge resection (LWR) - have been developed for these lesions.

Impact of robotic surgery proportion among minimally invasive gastrectomy on surgical complications.

Data of 14,076 patients who underwent gastric cancer surgery obtained from the 2019 Korean Gastric Cancer Association-led nationwide survey were used.

Deep learning using computed tomography to identify high-risk patients for acute small bowel obstruction: development and validation of a prediction model : a retrospective cohort study.

Objective: To build a novel classifier using an optimized 3D-convolutional neural network for predicting high-grade small bowel obstruction (HGSBO).

Summary Background Data: Acute SBO is one of the most common acute abdominal diseases requiring urgent surgery. While artificial intelligence and abdominal computed tomography (CT) have been used to determine surgical treatment, differentiating normal cases, HGSBO requiring emergency surgery, and low-grade SBO (LGSBO) or paralytic ileus is difficult.

Intracorporeal modified delta-shaped gastroduodenostomy during 2-port distal gastrectomy: technical aspects and short-term outcomes.

Purpose: Surgeons have become increasingly interested in reduced-port gastrectomy to minimize trauma while maintaining oncologic safety. Although gastroduodenostomy has the benefits of better nutritional outcomes and fewer postoperative complications than other types of reconstruction, gastroduodenostomy is not a preferred option for reduced-port distal gastrectomy because of technical difficulties. In this study, we describe our intracorporeal modified delta-shaped gastroduodenostomy technique, which is easily applicable during 2-port distal gastrectomy.

Prognostic impacts of participation in prospective surgical clinical trials on surgical outcomes in gastric cancer patients.

Various prospective surgical trials have been conducted on treating patients with gastric cancer. In clinical practice, patients and surgeons may hesitate to participate in prospective surgical trials due to trial-related complications. In this study, we evaluated the effects of participation in prospective surgical trials on surgical outcomes after radical gastrectomy for gastric cancer.

Prevention of Gallstones After Bariatric Surgery using Ursodeoxycholic Acid: A Narrative Review of Literatures.

Obesity by itself is a factor in the development of gallstone disease, and periods of weight loss after bariatric surgery further increase the risk of gallstone formation. In patients with obesity, hypersecretion of cholesterol may increase the risk of gallstone formation, which is approximately five-fold higher than that in the general population. The incidence of gallstone formation after bariatric surgery is 10-38% and often associated with a proportional increase in the risk of developing biliary complications.

Background: The KLASS-02 trial revealed that the oncologic outcomes of laparoscopic distal gastrectomy are not inferior to open distal gastrectomy in patients with advanced gastric cancer. The surgeons participating in this trial were chosen based on the assessment scores from the KLASS-02-QC trial, which used 22 items for standardization of D2 lymphadenectomy and quality control.

Secondary Primary Cancer after Primary Gastric Cancer: Literature Review and Big Data Analysis Using the Health Insurance Review and Assessment Service (HIRA) Database of Republic of Korea.

Advances in cancer screening and early detection, as well as improvements in surgical techniques and therapeutics, have contributed to decreasing gastric cancer mortality. The number of gastric cancer survivors continues to rise; however, long-term follow-up has revealed an increase in the risk of post-gastrectomy symptoms or other health problems, such as extra-gastric secondary primary cancer (SPC), in these survivors. Therefore, evidence-based screening for new primary cancer is needed in these populations; however, the incidence of SPC varies by country or continent and its characteristics have not been clearly reported.

Perspectives of laparoscopic surgery for gastric cancer.

Gastrectomy is the main treatment option for gastric cancer patients. Laparoscopic approach has become popular as an alternative to open method during the last decades, and clinical trials have revealed safety and feasibility in the short- and long-term outcomes of laparoscopic gastrectomy. The aim of this review is to summarize the results of prospective clinical trials and propose future perspectives for laparoscopic gastrectomy.

Background: Endoscopic submucosal dissection (ESD) application for patients with tumors beyond the expanded indication for ESD is inconclusive. This study aimed to identify the preoperative clinical features that can be curatively treated with ESD in patients with early gastric cancer (EGC) beyond the indication of ESD.

Methods: From 2006 to 2016, 673 patients who underwent gastrectomy for EGC beyond the expanded indication for ESD based on preoperative assessments were retrospectively reviewed.

Determination of Additional Surgery after Non-Curative Endoscopic Submucosal Dissection in Patients with Early Gastric Cancer: A Practically Modified Application of the eCura System.

Background: Additional surgery after non-curative endoscopic submucosal dissection (ESD) may be excessive as few patients have lymph node metastasis (LNM). It is necessary to develop a risk stratification system for LNM after non-curative ESD, such as the eCura system, which was introduced in the Japanese gastric cancer treatment guidelines. However, the eCura system requires venous and lymphatic invasion to be separately assessed, which is difficult to distinguish without special immunostaining.
