Background: Data on endoscopic resection (ER) for superficial duodenal epithelial tumors (SDETs) are insufficient owing to their rarity. There are two main ER techniques for SDETs: endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD). In addition, modified EMR techniques, such as underwater EMR (UEMR) and cold polypectomy, are becoming popular.

Recent reports have described the efficacy of the endoscopic shielding method with polyglycolic acid (PGA) sheets and fibrin glue for the prevention of adverse events after ESD. The aim of the present study was to investigate whether the PGA shielding method provides additional benefit in preventing post-ESD bleeding compared with standard care.

Due to the malignant potency of the lesion, endoscopic submucosal dissection (ESD) was performed. Microperforation occurred during ESD.

Rectourethral fistulais a relatively rare complication of radical prostatectomy but is extremely difficult to treat. We report a case with post-laparoscopic radical prostatectomy rectourethral fistula, treated with only endoscopic shielding.A 75-year-old man had undergone laparoscopic radical prostatectomy for prostate cancer, cT2cN0M0.

Perforations can occur during ESD, and clipping has been reported as useful for treating small pinhole perforations. However, it is often difficult to close postoperative perforations because they usually have large diameters, and the muscle layer around the perforated region is often fragile, so additional open surgery is the only currently used method to treat large perforations and delayed perforations.

We investigated the application of the combination of a polyglycolic acid (PGA) sheet and fibrin glue. PGA sheets comprise materials widely used in surgery for absorbable thread.

Methods: Nine endoscopists and a surgeon responded to a questionnaire on endoscopic diagnosis of SNADET. The subjects of this survey were histologically confirmed SNADET that were endoscopically or surgically resected from 2007 to 2012.
Aim: Although the treatment of early gastric cancer with endoscopic submucosal dissection (ESD) has been widely carried out, a standardized method of sedation for ESD has not been established. The purpose of the present study was to evaluate the efficacy and safety of sedation with dexmedetomidine (DEX).
Methods: We conducted a randomized study involving 90 patients with gastric tumors who were intended to be treated with ESD.

We present a 68 years old woman who was referred to our department due to impaired liver function. Hepatitis A IgM antibody and anti-nuclear antibody were positive, IgG, and gamma-globulin were elevated. Percutaneous liver biopsy was performed and autoimmune hepatitis was suspected pathologically.

The lymphoma involved the spleen, bilateral adrenal glands, and paraaortic lymph nodes of the abdomen. In both the bone marrow and lymph nodes, hemophagocytosis was evident, and the laboratory findings were consistent with HPS.
