Multicenter randomized control study of the efficacy of SO clip in colorectal endoscopic submucosal dissection (ESD). (SO clip study in colorectal ESD): Randomized controlled trial.

Introduction: Endoscopic submucosal dissection (ESD) allows the en bloc resection of colorectal epithelial tumors regardless of size. Although ESD is minimally invasive and yields favorable outcomes, it is technically difficult and requires a long procedure time. In addition, colorectal ESD is associated with a particularly high risk of complications, due to the thin bowel wall, bowel flexion, and peristalsis.

Traction method versus conventional endoscopic submucosal dissection for gastric epithelial neoplasms: A randomized controlled trial.

Introduction: Endoscopic submucosal dissection (ESD) is an advanced therapeutic technique for en bloc resection of superficial gastrointestinal neoplasms. Although gastric ESD is minimally invasive and provides favorable outcomes, it is technically difficult and requires a long procedure time for dissection. The traction-assisted approach overcomes some of the difficulties of gastric ESD, but its ability to reduce the procedure time remains unclear.

Add-on Pegylated Interferon Alpha-2a Therapy in Chronic Hepatitis B Japanese Patients Treated with Entecavir.

Entecavir requires long-term administration. Pegylated interferon (PEG-IFN) therapy leads to significant reduction of hepatitis B surface antigen (HBs Ag) levels. This study aimed to assess the safety and efficacy of adding PEG-IFN--2a to entecavir toward cessation of entecavir.

Serum pepsinogen levels can quantify the risk of development of metachronous gastric cancer after endoscopic resection.

We have previously reported that serum pepsinogen (PG) can quantify the level of gastric mucosal atrophy, and that H. pylori eradication reduces cancer development in subjects with mild atrophy identified by serum PG levels. The aim of this study was to elucidate the predictive ability of serum PG levels for the development of metachronous gastric cancer (MGC) after endoscopic resection (ER) of primary cancer in association with H.

[A case report of chronic intestinal pseudo-obstruction with autoimmune autonomic ganglionopathy suspected from seropositive results for anti-ganglionic acetylcholine receptor antibody].

A 37-year-old woman who had previously been diagnosed with idiopathic chronic intestinal pseudo-obstruction (CIPO) at another hospital was admitted to our institution with severe abdominal pain. She had a history of several abdominal surgeries to treat ileus at the previous hospital, and contrast-enhanced computed tomography on admission revealed subileus without any apparent causes of obstruction. Total parenteral nutrition, a gastrointestinal prokinetic agent, and opiates reduced persistent pain;however, breakthrough pain continued.

A case of chronic pancreatitis in which endoscopic ultrasonography was effective in the diagnosis of a pseudoaneurysm.

Endoscopic ultrasonography (EUS) was performed on a patient being treated for chronic pancreatitis because a submucosal tumor was observed in the stomach during gastrointestinal endoscopy. As internal pulsatile blood flow on Doppler was present, the diagnosis of an aneurysm was made. The pseudoaneurysm of the left gastric artery was embolized with histoacryl and lipiodol and the splenic artery was embolized with coils at the location of the pseudoaneurysm to prevent hemorrhage.

[Case of von Hippel-Lindau disease diagnosed by detection of multiple pancreatic endocrine tumors and renal tumor 13 years after bilateral adrenalectomy].

von Hippel-Lindau (VHL) syndrome is an inherited neoplastic syndrome caused by abnormity of the VHL gene found on the short arm of the chromosome 3. We reported a case of VHL disease diagnosed by the detection of multiple pancreatic endocrine tumors and renal tumor 13 years after bilateral adrenalectomy. A 40-year-old man presented with multiple pancreas tumors (maximum size 42 mm in diameter) detected by screening abdominal ultrasonography.
