[Preoperative Metallic Stent Placement and Neoadjuvant Chemotherapy for Locally Advanced Sigmoid Colon Cancer with Obstruction and Invasion of the Psoas Muscle-A Case Report].

A 77-year-old man was diagnosed with obstructive sigmoid colon cancer invading the psoas major and iliac muscles. To avoid the postoperative paralysis of the lower limb, a self-expandable metallic stent(SEMS)was placed, and systemic chemotherapy was administered subsequently. After 4 courses of SOX, Hartmann's procedure was performed.

Early-stage T1b adenocarcinoma arising in the remnant cystic duct after laparoscopic cholecystectomy: a case report and literature review.

Background: The cystic duct has been included in the staging classification scheme for gallbladder cancer since the 2010 publication of the AJCC Cancer Staging Manual (7th edition). To our knowledge, only seven other cases of adenocarcinoma arising in the remnant cystic duct following cholecystectomy have been reported in the English-language literature, and none has been reported as primary early-stage T1b remnant cystic duct cancer (CDC). We report, herein, a case of primary adenocarcinoma arising in the remnant cystic duct in a patient with history of laparoscopic cholecystectomy for gallstone disease.

Evaluating the effect of injecting triamcinolone acetonide in two sessions for preventing esophageal stricture after endoscopic submucosal dissection.

Several previous reports indicate that endoscopic injection of triamcinolone acetonide (TA) after widespread endoscopic submucosal dissection (ESD) is effective for preventing esophageal stricture. We investigated the efficacy of injecting TA in two sessions for preventing stricture formation post-ESD. Sixty-six consecutive patients with widespread mucosal defects that affected more than three-fourths of the circumference of the esophagus were included.

Urinary Podocalyxin as a Biomarker to Diagnose Membranous Nephropathy.

Background: A non-invasive diagnostic marker of membranous nephropathy (MN) is desirable. The urinary level of podocalyxin (PCX) is higher in various glomerular diseases, including MN. The aim of this study was to construct a diagnostic model of MN with the combination of urinary PCX and clinical parameters.
