AIM: To report the effects of the vitrectomy combined with Nd: YAG 532nm laser on treatment of retinal vasculitis. METHODS: Data of 36 cases (36 eyes) with retinal vasculitis undergoing vitrectomy and Nd:YAG 532nm laser treatment were analyzed retrospectively. RESULTS: Two cases were retinal arteritis, 4 cases were retinal phlebitis and 30 cases' damnification were on both artery and vein of retina in 36 cases. The damnification of lens was in 1 case, iatrogenic retinal hole was in 6 cases and dialysis of ora serrata was in 3 cases in operation. 2 cases were of retina detachment again, 2 cases of hyphema and 9 cases of ocular hypertension after operation. The best visual acuity of 36 cases were improved, which was 0.02 to 0.1 in 2 cases (6%), 0.12 to 0.4 in 22 cases (61%) and 0.5 to 1.0 in 12 cases (33%). CONCLUSION: Vitrectomy combined with Nd:YAG 532nm laser is an effective treatment for retinal vasculitis.

Background and study aims: Endoscopic submucosal dissection (ESD) is being increasingly used for superficial esophageal cancers. However, esophageal ESD is technically difficult, time consuming, and less safe compared with endoscopic mucosal resection (EMR). To perform ESD safely and more efficiently, various types of knives have been developed. This study compared the efficacy of our newly developed device, Mucosectom2, with that of conventional devices for esophageal ESD. Patients and methods: Between May 2007 and February 2011, ESD was performed for 172 esophageal lesions. Of these, 120 lesions were treated by conventional devices only, whereas 52 lesions were treated by conventional devices and the Mucosectom2. Procedure time, en bloc and R0 resection rates, and adverse events were retrospectively compared between the conventional and Mucosectom2 groups. Results: The median procedure time was 48.0 minutes in the conventional group and 21.5 minutes in the Mucosectom2 group; the procedure time was significantly shorter in the Mucosectom2 group than in the conventional group (P < 0.0001). The en bloc and R0 resection rates were lower in the conventional group than those in the Mucosectom2 group, although these differences were not significant. The rate of exposure of the muscle layer in the Mucosectom2 group was significantly lower than in the conventional group (P = 0.04). The rates of perforation and postoperative bleeding were not significantly different between the two groups. Conclusions: This feasibility study suggests that, compared with conventional ESD devices, the Mucosectom2 may decrease the time required for esophageal ESD. Although our groups appeared comparable, they were studied at different times. Endoscopic expertise and endoscope quality may have differed during these periods, thereby affecting the results of our study. A prospective trial is therefore required to confirm our results. © Georg Thieme Verlag KG Stuttgart, New York.

Aim: To investigate the clinical manifestations, endoscopic and ultrasonographic features, and endoscopic therapy of gastric inflammatory fibroid polyps (IFPs). Methods: A total of 13 patients with IFPs treated at our center were collected between January 2007 January and April 2014. The clinical data for these patients were reviewed. All patients underwent digestive endoscopy, and 5 patients whose lesions were located at the antrum underwent endoscopic ultrasonography before therapy. Therapeutic methods were selected based on endoscopic morphology of the lesion. Results: IFPs had a modest female predominance (8 women and 5 men), with the majority of patients (11) being more than 50 years. Involved sites included the stomach (10), ileum (2), and colon (1). The tumors ranged in size from 6-60 mm (mean, 21.62 mm). Endoscopic features of the 13 lesions were submucosal tumors (7), polyps (3) and neoplasms (3). All lesions were located in the second (2) or third (3) sonographic layer of the antrum without involvement of the fourth layer. Endoscopic ultrasonographic features were hypoechoic/homogeneous echo pattern and unclear boundary. Four patients underwent endoscopic mucosal resection (EMR), 6 underwent endoscopic submucosal dissection (ESD) and 3 partial gastrointestinalresection. All were confirmed histologically as IFPs. Conclusion: IFPs can occur throughout the gastrointestinal tract, commonly in the antrum. Understanding the characteristic digestive endoscopy and EUS features of IFP scan be helpful to IFP diagnosis. Treatmentby EMR or ESD iseffective and safe. © 2014 Baishideng Publishing Group Inc.

Background: There is no specific insertion method for patients who previously underwent an incomplete colonoscopy. No multicenter prospective study using a double-balloon endoscope (DBE) for total colonoscopy was previously performed. Objective: To demonstrate the effectiveness and safety of using short DBEs in patients who previously underwent incomplete colonoscopies. Design: A multicenter, prospective trial. Setting: Four tertiary care academic centers and 6 community hospitals. Patients: Patients with a history of incomplete colonoscopy, ages 20 to 79 years, were included. Exclusion criteria were colonoscopy performed by endoscopists with experience in fewer than 1000 cases, history of colectomy, poor bowel preparation, inflammatory bowel disease, active bowel obstruction, and active bleeding. Intervention: Total colonoscopies using short DBEs were attempted in all patients. Main Outcome Measurements: Primary endpoint was the cecal intubation rate. Secondary endpoints were time to cecal intubation, complications, and tolerability. Results: A total of 110 patients (62 males, median age 66.5 years) were included. Fifty-four patients had a history of abdominal surgery. The cecal intubation rate was 100% (110/110). Median intubation time was 12 minutes (range 447 minutes). Mild mucosal tears without symptoms occurred in 1 patient. For 64.5% of patients, intravenous sedatives and/or analgesics were used during examinations. Based on questionnaires, 50.9% had no pain, 31.8% slight pain, and 17.3% tolerable pain. Moreover, 96.4% of patients answered that their examination was more comfortable than their previous colonoscopy. Limitation: Uncontrolled trial. Conclusion: The use of a short DBE is an effective and safe method for total colonoscopy in patients who previously underwent incomplete colonoscopies.

Aim: To investigate and compare the effect on small bowel obstruction (SBO) of a long intestinal tube inserted by two different endoscopic placements which are transnasal ultrathin endoscopy and conventional endoscopy. Patients and Methods: Twenty-nine patients who had been diagnosed as suffering from SBO underwent long tube insertion placed by transnasal ultrathin endoscopy were included as subjects. Thirty-two patients who had undergone insertion of a long tube placed by conventional endoscopy were included as controls. The success rate of intubation of the small bowel, the time required for the procedure, and complications were compared between the subjects and controls. Results: The success rate of intubation was 100% (29/29) in subjects and 93.8% (30/32) in controls, without a significant difference (P = 0.493). There are 2 failed cases that the procedure was attempted near 60 min in 2 patients who had performed Billroth II anastomosis before, and the intestinal tube could not be inserted into efferent loops of jejunum in controls. The mean time required for the procedure was 15.3 min in subjects and 22.9 min in controls, respectively, and with a significant difference (P < 0.001). Epistaxis occurred in both groups, and 2 cases encountered bleeding of the gastrointestinal tract in controls. Conclusion: Long tube insertion facilitated by transnasal ultrathin endoscopy takes shorter time and has a higher success rate compared with the procedure conducted with the help of conventional endoscopy. It is safe and useful to insert a long intestinal tube assisted by transnasal ultrathin endoscopy for the decompression of small bowel. © 2015 Journal of Cancer Research and Therapeutics | Published by Wolters Kluwer - Medknow.
