RESUMO
INTRODUCTION: Although safe, colorectal endoscopic submucosal dissection (ESD) using a scissor-type knife has a slow resection speed. We aimed to evaluate the efficacy of a traction device to hasten the resection speed. METHODS: This multicenter randomized controlled trial was conducted at 3 Japanese institutions. Patients with a 20-50-mm superficial colorectal tumor were enrolled and randomly assigned to a conventional-ESD (C-ESD) group or a traction-assisted ESD (T-ESD) group. The primary outcome was the resection speed. RESULTS: The C-ESD and T-ESD groups comprised 49 and 48 patients, respectively. Although the mean resection speed was not significantly different in the entire cohort between the groups (23.7 vs 25.6 mm 2 /min, respectively; P = 0.43), it was significantly faster with T-ESD than with C-ESD at the cecum (32.4 vs 16.7 mm 2 /min, respectively; P = 0.02). The mean resection speed of tumors ≥30 mm tended to be faster by T-ESD than by C-ESD (34.6 vs 27.8 mm 2 /min, respectively; P = 0.054). The mean procedure time of T-ESD was significantly shorter than that of C-ESD (47.3 vs 62.3 minutes, respectively; P = 0.03). The en bloc (100% vs 100%), complete (98.0% vs 97.9%), and curative resection (93.9% vs 91.7%) rates were similar between the 2 groups. Perforation and delayed hemorrhage occurred in only 1 patient each in the T-ESD group. DISCUSSION: Although the resection rates were sufficiently high and adverse event rates were extremely low in both the groups, the use of a traction device for ESD in the proximal colon and for large lesions may increase the resection speed.

A 53-year-old man was admitted to our hospital with the complaint of neck pain and dyspnea. His blood examination revealed increased C-reactive protein and amylase levels. Enhanced computed tomography (CT) images demonstrated a retropharyngeal and a mediastinal low-density area extending to the portal area. He was diagnosed with pancreatic pseudocyst from the abdominal cavity to the cervical region accompanied by spontaneous rupture into the portal vein. Endoscopic ultrasound-guided cyst drainage (EUS-CD) of the most inferior cavity around the superior mesenteric artery was performed through the gastric wall. No adverse events were recorded during the procedure, and a near-complete resolution of his symptoms and the pseudocyst was achieved.

The patient was a terminally ill 80-year-old man with multiple lung metastases from hepatocellular carcinoma, that had developed following hepatitis-C virus-associated cirrhosis. He was admitted to our hospital with gingival bleeding, and we diagnosed gingival metastasis from hepatocellular carcinoma, based on histological examination. The bleeding could not be controlled, and the patient became dyspneic. After transcatheter arterial embolization, his bleeding was successfully controlled until his death due to respiratory failure. Transcatheter arterial embolization was a safe and effective treatment in our case.

Primary enterolith is a rare condition that can induce ileus and intestinal perforation. We report the first case of a true primary enterolith treated by balloon-assisted enteroscopy. The patient presented with a small intestinal ileus. After its improvement following the insertion of an ileus tube, radiography with amidotrizoate sodium meglumine detected a round, movable defect in the ileum measuring 42 mm diameter. The patient was diagnosed with a primary enterolith based on her past history. The enterolith was fractured and removed using balloon-assisted enteroscopy. This case suggests that balloon-assisted enteroscopy may be an effective non-invasive treatment option for enteroliths.

AIM: To evaluate the effectiveness of barium impaction therapy for patients with colonic diverticular bleeding. METHODS: We reviewed the clinical charts of patients in whom therapeutic barium enema was performed for the control of diverticular bleeding between August 2010 and March 2012 at Yokohama Rosai Hospital. Twenty patients were included in the review, consisting of 14 men and 6 women. The median age of the patients was 73.5 years. The duration of the follow-up period ranged from 1 to 19 mo (median: 9.8 mo). Among the 20 patients were 11 patients who required the procedure for re-bleeding during hospitalization, 6 patients who required it for re-bleeding that developed after the patient left the hospital, and 3 patients who required the procedure for the prevention of re-bleeding. Barium (concentration: 150 w%/v%) was administered per the rectum, and the leading edge of the contrast medium was followed up to the cecum by fluoroscopy. After confirmation that the ascending colon and cecum were filled with barium, the enema tube was withdrawn, and the patient's position was changed every 20 min for 3 h. RESULTS: Twelve patients remained free of re-bleeding during the follow-up period (range: 1-19 mo) after the therapeutic barium enema, including 9 men and 3 women with a median age of 72.0 years. Re-bleeding occurred in 8 patients including 5 men and 3 women with a median age of 68.5 years: 4 developed early re-bleeding, defined as re-bleeding that occurs within one week after the procedure, and the remaining 4 developed late re-bleeding. The DFI (disease-free interval) decreased 0.4 for 12 mo. Only one patient developed a complication from therapeutic barium enema (colonic perforation). CONCLUSION: Therapeutic barium enema is effective for the control of diverticular hemorrhage in cases where the active bleeding site cannot be identified by colonoscopy.
