The number of gastrointestinal stomas registered in the NCD during the study period was approximately 25,000 per year, with a moderate increase during 2013–2018. The number of stoma closures was 10,000–14,400 per year. The number of stoma closures has also increased.

R0 resection of conversion therapy can be a new strategy for gastric cancer.

Specific GIST genotypes were significantly associated with a risk of recurrence. Genotype analysis may be useful for predicting the prognosis and determining the indications for adjuvant imatinib in patients with GIST.

This study included 68 UC patients who underwent IPAA with diverting ileostomy and these cases were analyzed based on clinicopathological factors and CT-based anatomical factors. Height adjusted the root of their superior mesenteric artery and the bottom of the external anal sphincter (rSMA-bEAS; >191.0 mm/m) and male sex were independent risk factors associated with SOO. A long rSMA-bEAS distance suggests that the mesentery is likely to be under tension. In such cases, surgeons should endeavor to avoid tension in the mesentery as much as possible.

In the porcine model, anastomoses created using the triple-layered circular stapler had higher bursting pressure than the double-layered stapler. Furthermore, in the multicenter clinical cohort, the use of the triple-layered circular stapler was independently associated with the absence of anastomotic leakage.

Grip strength is an independent predictor of postoperative delirium in elderly patients with colorectal cancer, along with the MMSE, GDS, and age ≥78. It is easy to measure and should be used to prepare for postoperative delirium before surgeries.

We show that elderly patients, smokers, and patients with comorbidity are more likely to develop complicated appendicitis (CA), and emergency surgery for CA places the patient at a relatively higher risk than emergency surgery for uncomplicated appendicitis (UA). The importance of this study is that patient backgrounds suggesting the difference in the pathogenesis of CA and UA and surgical outcomes after emergency surgery for CA and UA are shown using a nationwide database.

This study explored the usefulness of an anal sphincter injury mouse model by means of a balloon catheter and examined the efficacy of electrical stimulation as a treatment modality using this model.

The mesopancreas or mesopancreatoduodenum is an important anatomical concept during pancreaticoduodenectomy (PD) in patients with periampullary carcinoma. This study investigated whether the duodenojejunal uncinate process vein (DJUV), which is defined as the vein draining from the upper jejunum to the superior mesenteric vein adjacent to the uncinate process, is a useful anatomical landmark for the caudal border of mesopancreatoduodenum resection during PD.

We propose a new scoring system to predict the necessity of a bailout procedure during LC after PTGBD, using significant predictors of time until PTGBD after symptom onset and the maximal wall thickness of GB. Our scoring system for the necessity of the bailout procedure seems to provide a precise prediction and might be associated with the risk of BDI. It might be better to select flexibly laparoscopic subtotal cholecystectomy or open cholecystectomy from the beginning for patients with a score of 2 after PTGBD.

The preoperative CA19-9 value of ≥37 U/mL reflected a systemic disease status. In this patient group, R0 resection did not affect the survival.
