Background: Docking the scope and instruments through a multi-channel trocar has enabled reduced-port robotic distal gastrectomy (RRDG) for gastric cancer. To facilitate lymphadenectomy over the anatomical hindrances during RRDG, we recently introduced the Vessel Sealer Extend (VSE) (Intuitive Surgical, Sunnyvale, CA, USA), a bipolar vessel-sealing device (BVSD) with an articulating jaw.
Methods: From May 2020 to August 2023, we performed RRDG to treat T1 gastric cancer. One endoscope arm and three instrument arms of the da Vinci Xi Surgical System (Intuitive Surgical) were used. During the lymphadenectomy, the endoscope and VSE (Intuitive Surgical) were docked through a multi-channel trocar established on a trans-umbilical incision. Two Cardiere forceps were docked through cannulas established on each flank. A trans-umbilical lymphadenectomy using an articulating BVSD (TULAB) was then performed.
Results: A total of 42 patients underwent planned RRDG with the TULAB technique. The number of retrieved lymph nodes did not differ between the patients who underwent RRDG and those who underwent conventional laparoscopic distal gastrectomies (CLDG) ( = 0.362). There was no statistically significant difference in postoperative complications between the RRDG and CLDG group ( = 0.189). The mean time to first semi-fluid diet was shorter in the patients who underwent RRDG than CLDG ( = 0.030), and the incidence of postoperative ileus was lower in the RRDG group than the CLDG group (0% and 9.9%, respectively, = 0.034).
Conclusions: Despite use of fewer ports, RRDG with TULAB had similar outcomes to CLDG in terms of the incidence of postoperative morbidity and the number of harvested lymph nodes. Furthermore, by reducing the number of incisions, the incidence of the intra-abdominal adhesions can potentially be lowered when RRDG is used.

Purpose: To assess and compare the diagnostic efficiency of histogram analysis of monochromatic and iodine images derived from spectral CT in predicting Ki-67 expression in gastric gastrointestinal stromal tumors (gGIST).
Methods: Sixty-five patients with gGIST who underwent spectral CT were divided into a low-level Ki-67 expression group (LEG, Ki-67 < 10%, n = 33) and a high-level Ki-67 expression group (HEG, Ki-67 ≥ 10%, n = 32). Conventional CT features were extracted and compared.

Background: GI cancers pose an increasing global health burden, with their impact on the working-age population (WAP) aged 15-64 years remaining largely unexplored despite the crucial role of this group in societal and economic well-being.
Objective: To assess trends and cross-country inequality in the global burden of six GI cancers from 1990 to 2021 among individuals in the WAP.
Design: The 2021 Global Burden of Disease study dataset was used to obtain estimates of GI cancer incidence and 95% uncertainty intervals, including the number of cases, crude incidence rate and age-standardised incidence rate (ASIR).

Background/aim: The effect of left ventricular systolic dysfunction (LVSD), a risk factor for postoperative mortality, in older adult patients with gastric cancer has not been fully elucidated. This study aimed to evaluate the impact of low preoperative left ventricular ejection fraction (EF) on short- and long-term outcomes in older adult patients with gastric cancer.
Patients And Methods: This retrospective study enrolled 237 older adult patients with gastric cancer (≥75 years old) who underwent preoperative echocardiography and curative gastrectomy.

Background/aim: Body weight loss (BWL) after gastrectomy for gastric cancer (GC) decreases postoperative quality of life and survival in patients with GC. This study aimed to evaluate the effect of oral nutritional supplements composed of high protein on BWL in the early period following gastrectomy.
Patients And Methods: Pre- and postoperative body weight and skeletal muscle mass were measured using bioelectrical impedance analysis in patients undergoing radical gastrectomy for GC and analyzed retrospectively.
