Methods: We created a cuboid box (500 × 650 × 450 mm) with four sides were covered with a transparent, vinyl-chloride sheet having two windows for endoscopic passage and assistance.

[Endoscopic closure of an esophago-pleural fistula resulting from a perforated esophageal ulcer due to systemic sclerosis:filling and shielding using polyglycolic acid sheets and fibrin glue].

A woman in her 70s with systemic sclerosis experienced dyspnea, and consequently, she was diagnosed with an esophago-pleural fistula, which was caused by a perforated esophageal ulcer. We administered conservative treatments including continuous pleural drainage and total parenteral nutrition. The fistula was closed but recurred, at which point we attempted to close the fistula by filling and shielding using polyglycolic acid (PGA) sheets and fibrin glue (FG).

Filling of Polyglycolic Acid Sheets for Closure of Gastrointestinal Fistulas With an Easily Deliverable Technique Using a Guidewire.

Background: This retrospective study aimed to investigate the suitable indications, methodology and long-term effect of the closure of gastrointestinal (GI) fistulas using polyglycolic acid (PGA) sheets and fibrin glue (FG) and to evaluate the usefulness of a delivery technique using a guidewire.

Methods: It involved 10 applications in six patients (median age 73 (range 53 - 78) years old, three men) with GI fistulas. A guidewire was introduced endoscopically or percutaneously into the fistula beyond the opposite orifice of the fistula with radiologic control.

IgG4-related Autoimmune Hepatitis with a Suspected Drug-induced Etiology.

A 69-year-old man was referred to our department with acute hepatitis. He had been newly treated with benidipine hydrochloride for two months. His blood test results were as follows: aspartate aminotransferase, 1,614 IU/L; alanine aminotransferase, 1,091 IU/L and anti-smooth muscle antibody, ×80.

Endoscopic Gastrojejunostomy for Superior Mesenteric Artery Syndrome Using Magnetic Compression Anastomosis.

An 89-year-old woman who was bedridden suffered repeated vomiting due to superior mesenteric artery syndrome (SMAS). We performed gastrojejunostomy via the magnetic compression anastomosis (MCA) technique because her situation was not improved by conservative therapy and because the operative risk was high. We prepared two neodymium magnets: a flat plate-shaped magnet (15 × 3 mm) and a ring-shaped magnet of the same size.

A rare case of Goodpasture syndrome concomitant with bleeding jejunal Dieulafoy's lesion.

An 81-year-old man was diagnosed with Goodpasture syndrome (GS) because he met the criteria of positive anti-GBM antibodies, rapid progressive glomerulonephritis and pulmonary hemorrhage. After starting plasmapheresis and steroid pulse therapy, he experienced tarry stool and contrast-enhanced CT revealed an aneurysmal finding in the jejunum. Paroral enteroscopy showed a jejunal Dieulafoy's lesion (DL) with gush-out hemorrhage.

Experience of Endoscopic Jejunojejunostomy for Anastomotic Obstruction After Subtotal Gastrectomy Using Magnetic Compression Anastomosis.

Magnetic compression anastomosis (MCA) was developed as a low-invasive treatment for gastro-enteric or entero-enteric obstruction. A 72-year-old man underwent subtotal gastrectomy with Billroth II reconstruction for early gastric cancer. After the operation, he suffered from repeated aspiration pneumonia due to anastomotic obstruction caused by jejunal kinking at the efferent loop of anastomosis.

Prophylactic Biliary Stenting Before Cholecystectomy in Patients With Gallstones and Common Bile Duct Stones.

Background: The usefulness of prophylactic biliary stenting for patients with common bile duct stones (CBDS) and gallstones (GS) to prevent recurrent biliary events after endoscopic sphincterotomy (EST) and CBDS extraction before elective cholecystectomy remains controversial. The aim of this study was to evaluate the risk of recurrent CBDS around the perioperative period and clarify its risk factors.

Methods: The clinical data of all patients who received prophylactic biliary stenting after EST for CBDS and later underwent cholecystectomy for GS followed by stent extraction in our institution were retrospectively reviewed.

Experience of Manual Compression Hemostasis Under Endoscopic Observation for Acute Hemorrhagic Rectal Ulcer.

We experienced two cases in which manual compression hemostasis under endoscopic observation was used in patients with acute hemorrhagic rectal ulcer (AHRU). The patients experienced an episode of massive fresh hematochezia, requiring the blood transfusion. Emergent sigmoidoscopy revealed multiple ulcers with a large protuberant visible vessel or with gush-out hemorrhage on the lower rectum.
