Objective: To evaluate the short-term outcomes of laparoscopic distal gastrectomy and robotic distal gastrectomy performed during the same period.

Methods: This study enrolled 46 cases of laparoscopic distal gastrectomy and 67 cases of robotic distal gastrectomy that were performed by a single surgeon between April 2020 to October 2021. Baseline characteristics and short-term outcomes of these two groups were then compared. Moreover, the robotic distal gastrectomy group was further divided into two subgroups according to the learning curve. Finally, the baseline characteristics and short-term outcomes of both subgroups were compared with the laparoscopic group, respectively.

Results: The baseline characteristics and short-term outcomes of the LDG group and RDG group were comparable. In contrast, the operation time in the laparoscopic group was significantly shorter than that in the early experience robotic group (191.3 ± 37.6 VS 225.1 ± 49, P=0.001). However, the operation time (191.3 ± 37.6 VS 185.3 ± 25.3, P=0.434) was comparable between the laparoscopic group and the late experience robotic group. Likewise, the bleeding volume was comparable between the laparoscopic and early experience robotic groups. However, bleeding volume was significantly lower in the late experience robotic group compared to that in the laparoscopic group (37.5 ± 18.8 VS 49.2 ± 29.0, P=0.049).

Conclusions: With surgeons stepping into the stable stage of the robotic learning curve, RDG showed a comparable operation time and lower volume of blood loss compared with LDG. Collectively, our study supports the application of robotic distal gastrectomy in patients diagnosed with gastric cancer.

Purpose: Since 1995, the Korean Gastric Cancer Association (KGCA) has been periodically conducting nationwide surveys on patients with surgically treated gastric cancer. This study details the results of the survey conducted in 2023.

Materials And Methods: The survey was conducted from March to December 2024 using a standardized case report form.

Background: Ensuring a pathologically negative distal margin (DM) and preserving a larger remnant stomach is important for proximal gastrectomy (PG) in patients with esophagogastric junction (EGJ) cancer. However, the minimum DM length for ensuring negative margins has not been identified.

Methods: We enrolled patients undergoing PG or total gastrectomy for EGJ cancer.

Background: Although bariatric and metabolic surgical methods, including duodenal-jejunal bypass (DJB), were shown to improve metabolic dysfunction-associated steatotic liver disease (MASLD) in clinical trials and experimental rodent models, their underlying mechanisms remain unclear. The present study therefore evaluated the therapeutic effects and mechanisms of action of DJB in rats with MASLD.

Methods: Rats with MASLD were randomly assigned to undergo DJB or sham surgery.

Purpose: Obesity and type 2 diabetes (T2DM) are major risk factors for hepatic steatosis. Diet or bariatric surgery can reduce liver volume, fat content, and inflammation. However, little is known about their effects on liver function, as evaluated here using the LiMAx test.

Objective: The laparoscopic approach for locally advanced gastric cancer has recently been adopted based on the results of several randomized controlled trials (RCTs). However, findings from RCTs have not been examined at the national level. This study aimed to investigate the external validity of the Korean Laparoscopic Gastrointestinal Surgery Study-02 (KLASS-02) trial involving 13 tertiary hospitals, using data from the Korean Gastric Cancer Association (KGCA)-led nationwide survey involving 68 tertiary or general hospitals.
