Open AccessComparison between the mesenteric fixation method (MEFIX) and conventional methods at preventing the occurrence of Petersen’s hernia: a study protocol for a multicenter randomized controlled trial
Petersen’s hernia, which occurs after Billroth-II (B-II) or Roux-en-Y (REY) anastomosis, can be reduced by defect closure. This study aims to compare the incidence of bowel obstruction above Clavien–Dindo clas...

Actual 3-Year Survival After Reduced-Port Laparoscopic Distal Gastrectomy for Gastric Cancer (RpLDG): a Propensity Score Matching Analysis
Total laparoscopic distal gastrectomy for early gastric cancer has been widely accepted; however, reduced-port laparoscopic distal gastrectomy has not gained the same popularity because of technical difficulti...

Digital image analysis-based scoring system for endoscopic ultrasonography is useful in predicting gastrointestinal stromal tumors
When gastric mesenchymal tumors (GMTs) measuring 2–5 cm in size are found, whether to undergo further treatment or not is controversial. Endoscopic ultrasonography (EUS) is useful for the evaluation of maligna...

Tumor localization using radio-frequency identification clip marker: experimental results of an ex vivo porcine model
With the widespread use of minimally invasive surgery, tumor detection is becoming more difficult. We present the experimental results of a radio-frequency identification (RFID) lesion detection system in an e...

Long-term outcome of endoscopic submucosal dissection is comparable to that of surgery for early gastric cancer: a propensity-matched analysis
Data concerning the long-term outcomes of endoscopic submucosal dissection (ESD) versus surgery for early gastric cancer (EGC) are limited. We aimed to compare the long-term outcomes of ESD and surgery for pat...

Open AccessTwo staging systems for gastrointestinal stromal tumors in the stomach: which is better?
The prognosis of a gastrointestinal stromal tumor (GIST) is influenced by its anatomic site; however, few studies on the prognosis of gastric GISTs have been reported. The aims of this study were to evaluate l...

Risk factors for local recurrence in patients with positive lateral resection margins after endoscopic submucosal dissection for early gastric cancer
With the widespread use of endoscopic submucosal dissection (ESD) in patients with early gastric cancer (EGC), the number of cases with incomplete resection due to positive lateral resection margins (LM+) is i...

Open AccessOverexpression of Snail is associated with lymph node metastasis and poor prognosis in patients with gastric cancer
Epithelial–mesenchymal transition (EMT) plays a significant role in tumor progression and invasion. Snail is a known regulator of EMT in various malignant tumors. This study investigated the role of Snail in g...

Cancer spheres from gastric cancer patients provide an ideal model system for cancer stem cell research
Cancer stem cells have been hypothesized to drive the growth and metastasis of tumors. Because they need to be targeted for cancer treatment, they have been isolated from many solid cancers. However, cancer st...

Massive hemoperitoneum due to ruptured inferior phrenic artery pseudoaneurysm after blunt trauma
There had been no previous reports of ruptured pseudoaneurysm of inferior phrenic artery shortly after blunt abdominal trauma. Traumatic arterial pseudoaneurysms are either iatrogenic or the result of penetrat...
