We report our experience in a patient with adenoma located in the horizontal part of the duodenum, which was effectively treated with the transmesenteric laparoscopic endoscopic cooperative surgery (LECS) approach. This approach, which entails incising the mesentery of the colon, simplified laparoscopic access to the horizontal part of the duodenum, which was minimally mobilized. Thus, the bulb and descending part of the duodenum were fixed to the retroperitoneum, facilitating stable handling of the endoscope and enabled safe and effective excision of an adenoma located in the horizontal part of the duodenum. This approach enabled safe and effective excision of an adenoma located in the horizontal part of the duodenum. The advantages of this method include a secure field of view, lower probability of damage to large vessels, and minimizing the defect to the intestine caused by the incision.

Multiple endocrine neoplasia type 1 (MEN1) is a rare autosomal dominant disease with an estimated prevalence of 2 per 100,000. This disease is caused by a mutation in the tumor suppressor gene MEN1, which is located on chromosome 11 and codifies the menin protein. It is characterized by a predisposition of parathyroids, enteropancreatic, and anterior pituitary tumors, affecting the quality of life and lifespan of those who have the disease.

An asymptomatic 79-year old woman presented with a 40 mm pancreatic cystic lesion, located in the pancreatic body-tail and consistent with branch-duct intraductal papillary mucinous neoplasm (BD-IPMN) without "high risk stigmata". During a 4-year follow-up period, imaging showed no mural nodules or main pancreatic duct dilation, and serum CEA and CA19.9 were within normal range.

The rare gastrointestinal tract epithelial polyp known as a pyloric gland adenoma (PGA) is more common in elderly women and uncommon in the duodenum. There are reports of two PGA cases involving high-grade intraepithelial neoplasia. A 75-year-old man was admitted to the hospital as Patient 1 due to "epigastric distension and pain for more than 10 days".

Purpose: We examined operative efficiency, rate of facial nerve paresis, and post-operative outcomes in patients undergoing retrograde (RGD) vs anterograde dissection (AGD) of the facial nerve controlling for tumor location.
Methods: Single-institution, retrospective analysis of patients with benign parotid tumors undergoing superficial parotidectomy with facial nerve dissection over a six-year period. Operative and pathology reports were reviewed to classify tumor size, location in relation to facial nerve branches, and technique for facial nerve dissection.

Purpose: This study examined the roles of nuclear factor erythroid 2-related factor 2 (NRF2) and programmed death ligand 1 (PD-L1) in colon carcinogenesis, underscoring on sex and differences in tumor location.
Materials And Methods: A total of 378 participants were enrolled from Seoul National University Bundang Hospital: 88 healthy controls (HC), 139 patients with colorectal adenoma (AD), and 151 patients with colorectal cancer (CRC). Quantitative real-time polymerase chain reaction (PCR), methylation-specific PCR, and immunohistochemistry (IHC) were performed utilizing tumor samples from patients and normal mucosa in the HC group.
