Low-profile visualized intraluminal support deployment in an Enterprise has been reported; however, that in an Atlas has yet to be in detail. Enterprise has a closed-cell design, while Atlas has an open-cell design. We detail here a case of a large wide-necked aneurysm treated by coil embolization with low-profile visualized intraluminal support Blue deployment within a Neuroform Atlas and a bench-top experiment using a silicon tube to test low-profile visualized intraluminal support, Atlas, Enterprise, and their combinations. A better low-profile visualized intraluminal support expansion was achieved by simultaneously pushing the wire and the system within the Atlas placed at the aneurysm neck, which resulted in an increased metal coverage of the aneurysm neck and a shorter transition zone with low metal coverage at both ends of the aneurysm neck. This technique may enable a high metal coverage by low-profile visualized intraluminal support expansion without restriction by the Atlas and contribute to aneurysm occlusion by increasing the flow-diverting effect.

Objectives: The objective of the study was to compare the outcome of Classical Dacrocystorhinostomy(DCR) alone or with Slicon intubation in patients of primary nasolacrimal duct obstruction.Study design: This is a randomized prospective interventional study performed at Saidu Teaching Hospitalform from 1st January'2006 to 31st December 2006.Material and methods: Diagnosis of nasolacrimal duct obstruction was made on basis of history, clinicalexamination, regurgitation test and syringing of the nasolacrimal passage. Patients were selected byconvenient sampling and were randomized to two groups, for DCR with and without Silicon tube. Silicontube was removed after 4 months of surgery. Patients were followed up to 6 months.Results: Total number of patients was one hundred. Fifty (50%) patients were operated with siliconintubation and 50 (50%) without silicon intubation. Male to female ratio was 1:1.27.Age range was 15 yearsto 80 years. Mean, median and mode ages were 42.54, 47 and 30 years respectively. Eleven patients werelost from the study at various stages and were not included in the results of the study. The complicationsnoted were silicon tube loss in 2 cases, silicon tube displacement in 3 cases and DCR failure in 4 cases.Among the failure, 2 cases belonged to each group with and without silicon intubation.Conclusions: We conclude that the complications rate with and without silicon intubation is the same inprimary nasolacrimal duct obstruction. It is therefore, recommended that silicon intubation may not benecessary in such cases.Key words: DCR, Intubation, NLD Obstruction.

Abstract Background The presence of urinary fistula after ileal conduit urinary diversion is a challenging complication, and this study investigated the role of the intra-conduit negative pressure system (NPS) in the presence of urinary fistula following ileal conduit (IC) urinary diversion as a conservative treatment. Methods Using the intra-conduit NPS, a minor drainage tube was placed within a silicon tube to suck urine from the conduit with consistent negative pressure. Patients with urinary fistula following IC from August 2012 to July 2017 were recorded, and the clinical characteristics and outcome were retrospectively analyzed. Results The intra-conduit NPS was used as a primarily conservative treatment for 13 patients who suffered from urinary fistula and presented with a large amount of abdominal/pelvic drainage without other significant morbidities. The median age was 60 years old (42–74 years), and 7patients were male. The median duration between the IC operation and the presence of urinary fistula was 15 days (2–28 days), and elevated creatinine levels were detected in the abdominal/pelvic drainage with a median level of 2114 μmol/L (636–388 μmol/L). A significant decrease in abdominal/pelvic drainage was identified in 12 patients. The median time that the NPS was used was 9 days (7–11 days). The other patient did not show any improvements after 2 days of observation and then underwent open surgery. With ureteral stenting, 2 abdominal drainage tubes and the intra-conduit NPS were placed during operation, no urine leakage was observed in the abdominal/pelvic field, and the patient was cured in 9 days. With a median follow-up of 22 months, no fistula recurrence or hydronephrosis was detected. Conclusion The intra-conduit negative pressure system is a feasible and promising way to cure urinary fistula following ileal conduit urinary diversion. Because this procedure is a mini-invasive and simple approach, it might represent an alternative in selected patients.

External Dcr

Dacryocystorhinostomy (DCR) is a bypass surgery in which an anastomosis is made between the medial wall of the lacrimal sac & the lateral wall of the nasal mucosa by cutting the intervening bone at the level of middle meatus to restore the flow of tears when the obstruction is beyond the common canaliculus. The only successful treatment of chronic dacryocystitis is DCR. The aim of this study was to evaluate the surgical intervention of conventional external DCR without silicon tube intubation. This prospective study was conducted at General Hospital, Faridpur from July 2012 to June 2014. Eighty cases with chronic dacryocystitis were selected for the study. We excluded the patients with lacrimal fistula, failed DCR and gross nasal pathology like deviated nasal septum, grossly hypertrophied inferior turbinate, atrophic rhinitis, nasal tumour, and polyp from our study. The patients' mean age at the time of surgery was 41.9±8.1 years ranged from 30 to 60 years. The operation was done under local anaesthesia by applying same technique. Then the patients were followed up for 12 months. In this study, we observed recurrence in five patients (6.25%) and complications from DCR are infrequent and not sight threatening. There were seven patients with reactionary haemorrhage, one wound infection, three wound gap, two epicanthal fold, one granuloma formation and five failed DCR. The success rate is 93.75% who underwent external DCR for the management of epiphora due to nasolacrimal duct obstruction.Faridpur Med. Coll. J. Jan 2015;10(1): 20-22
