Factors related to difficult self-expandable metallic stent placement for malignant colonic obstruction: A post-hoc analysis of a multicenter study across Japan.

Background And Aim: Colorectal cancer patients often present with large bowel obstruction. Elective placement of a self-expandable metallic stent (SEMS) can relieve obstruction, but can be challenging. Previous studies have compared cases by outcomes only, but the present study investigated successful cases only to identify factors related to prolonged and difficult SEMS placement in patients with malignant colonic obstruction.

Transformation of jejunoileal follicular lymphoma into diffuse large B-cell lymphoma detected using double-balloon enteroscopy.

Jejunoileal follicular lymphomas (FLs) are rare and have been reported to undergo histological transformation (HT). We report a case of jejunoileal FL transformation into diffuse large B-cell lymphoma (DLBCL). An 82-year-old woman presented with a 5.

Gastric and enteric anisakiasis successfully treated with Gastrografin therapy: A case report.

We report a case of a 59-year-old woman who was diagnosed with gastric and small intestinal anisakiasis, which was successfully treated with endoscopic extraction and Gastrografin therapy. She was admitted to our hospital with epigastric pain and vomiting one day after eating raw fish. She exhibited tenderness in the epigastrium without obvious rebound tenderness or guarding.

Endoscopic submucosal dissection of early colorectal neoplasms with a monopolar scissor-type knife: short- to long-term outcomes.

 Endoscopic submucosal dissection (ESD) for colorectal neoplasms remains challenging because of technical issues imposed by the complex anatomical features of the large intestine. We evaluated the feasibility, and the short- and long-term clinical outcomes of ESD for early colorectal neoplasms performed using the Stag-beetle Knife Jr. (SB Knife Jr.

[A case of ileus due to radiation enteritis 19 years after radiotherapy].

A 73-year-old female visited our hospital complaining of nausea and epigastric pain because of ileus. She had a history of two laparotomy procedures in her youth, interferon treatment for chronic hepatitis C, and radiation therapy for uterine cervical cancer 19 years ago. Transanal double-balloon enteroscopy demonstrated annular stenosis with ulceration of the anal side of the dilated small intestine.

Safety and efficacy of self-expandable metallic stents in malignant small bowel obstructions.

In this report, we present 3 cases of malignant small bowel obstruction, treated with palliative care using endoscopic self-expandable metallic stent (SEMS) placement, with the aim to identify the safety and efficacy of this procedure. Baseline patient characteristics, procedure methods, procedure time, technical and clinical success rates, complications, and patient outcomes were obtained. All 3 patients had pancreatic cancer with small bowel strictures.

Clinical usefulness of transabdominal ultrasonography prior to patency capsule for suspected small-bowel strictures.

Objective: Patency capsule (PC) examination has made it possible to perform capsule endoscopy (CE) in patients with a suspected small-bowel stricture. However, PC has some drawbacks, so we assessed the usefulness of transabdominal ultrasonography (TUS) prior to PC in patients with suspected small-bowel strictures to avoid unnecessary PC examination.

Patients And Methods: Fifty-two patients who underwent TUS prior to PC were enrolled in this study.

A trial of the use of patency capsules in combination with overnight capsule endoscopy.

Background: The PillCam® patency capsule (PPC) was developed to minimize the risk of capsule retention during capsule endoscopy (CE). Typically, the use of patency capsules prior to CE requires patients to be monitored over a period of time. To reduce the need for frequent outpatient visits during PPC examination and CE, we developed the overnight CE (ON-CE) procedure.

Effectiveness of polaprezinc for low-dose aspirin-induced small-bowel mucosal injuries as evaluated by capsule endoscopy: a pilot randomized controlled study.

Background: Treatment of low-dose aspirin (LDA)-induced small-bowel injury has not been established. Polaprezinc, a chelate of zinc and L-carnosine, may be efficacious for such injury. We conducted a pilot randomized controlled study to investigate whether polaprezinc is effective against LDA-induced small-bowel injuries.

Feasibility of spiral enteroscopy in Japanese patients: study in two tertiary hospitals.

Background And Aim: Despite recent advances in enteroscopy, such as balloon enteroscopy, accessing the small intestine remains challenging. Spiral enteroscopy is a novel technique in which an endoscope is fitted with a rotating overtube that has a soft spiral fin at the tip. Whereas spiral enteroscopy is beginning to be carried out in Western countries, it is not common in many Asian countries.

Diagnostic yield of capsule endoscopy vs. double-balloon endoscopy for patients who have undergone total enteroscopy with obscure gastrointestinal bleeding.

Background/aims: The usefulness of capsule endoscopy (CE) and of double-balloon endoscopy (DBE) for detection of small-bowel lesions is widely accepted. We compared CE- and DBE-based detection of small-bowel lesions in patients with obscure gastrointestinal bleeding (OGIB) who underwent total enteroscopy by both CE and DBE.

Methodology: One hundred eighteen consecutive patients (70 men, 48 women; mean age 62.

Outcome of patients who have undergone total enteroscopy for obscure gastrointestinal bleeding.

Aim: To assess the diagnostic success and outcome among patients with obscure gastrointestinal bleeding who underwent total enteroscopy with double-balloon endoscopy.

Methods: Total enteroscopy was attempted in 156 patients between August 2003 and June 2008 at Hiroshima University Hospital and achieved in 75 (48.1%).

Removal of a sewing needle penetrating the wall of the third portion of the duodenum by double-balloon endoscopy.

We describe successful removal a sewing needle penetrating the wall of the third portion of the duodenum by means of double-balloon endoscopy (DBE). The patient was a 47-year-old woman who accidentally swallowed a sewing needle and was admitted to our hospital. Abdominal radiography and abdominal computed tomography revealed a metallic object in the third portion of the duodenum.

Risk factors for bleeding after endoscopic submucosal dissection of gastric epithelial neoplasm.

Background: Although endoscopic submucosal dissection (ESD) is standard therapy in Japan for gastric epithelial neoplasm, the complication rate is unsatisfactory, with postoperative bleeding as the major complication. The aim of the present study was to determine risk factors for post-ESD bleeding in patients with gastric epithelial neoplasm.

Patients And Methods: The study included 764 patients in whom 924 gastric epithelial neoplasms were resected endoscopically between June 2005 and December 2009: the period during which preventative coagulation for all exposed vessels on the artificial ulcer with hemostatic forceps upon completion of ESD was performed routinely.

Clinical validity of endoscopic submucosal dissection for submucosal invasive gastric cancer: a single-center study.

Background: The 2010 Japanese Gastric Cancer Association guidelines for the treatment of submucosal invasive gastric cancer (SM-GC) specify size 30 mm or less, differentiated-dominant histology, lack of vessel involvement, and submucosal invasion of less than 500 μm (SM1) as expanded criteria for curative endoscopic resection. Our purpose in this study was to confirm the validity of the expanded indications for curative endoscopic submucosal dissection (ESD) of SM-GC.

Methods: The study subjects were 173 patients with SM-GC resected by ESD at Hiroshima University Hospital between April 2002 and September 2010, including 99 patients for whom 3-plus years' follow-up information was available.

Improved detectability of small-bowel lesions via capsule endoscopy with computed virtual chromoendoscopy: a pilot study.
