Filter by:The use of synthetic mesh to repair infected defects of the abdominal wall remains controversial. This study aimed to evaluate the short-term outcomes of using PVDF mesh to treat infected abdominal wall defects in the elective setting.
To investigate the associated risk factors of rectovaginal fistula
While some investigators found oral metronidazole to be effective in reducing pain after hemorrhoidectomy, other researchers did not find a significant analgesic effect of systemic metronidazole. On the other hand, topical application of metronidazole had more consistent favorable results as Ala et al documented a remarkable analgesic effect of topical metronidazole 10% after excisional hemorrhoidectomy which was in line with Nicholson and Armestrong who also concluded similar results. No previous study compared the analgesic effect of topical and oral metronidazole after anorectal surgery. Therefore, the present trial was conducted to compare the impact of oral versus systemic metronidazole on pain and recovery after surgery for benign anorectal conditions.
A prospective, multi-center, randomized (1:1) clinical study evaluating the FLEX Vessel Prep device plus percutaneous angioplasty (PTA) (study arm) vs PTA alone (control arm) for the treatment of obstructive lesions in the native arteriovenous dialysis fistulae.
Cerebral blood flow (CBF) is of paramount importance to human brain function, as the brain relies on a continuous blood supply to meet its energy needs. Blockage of a cerebral blood vessel during neurosurgery, even if transient and short-lived, may result in irreversible brain tissue damage (i.e. stroke) and loss of cortical function, if not identified quickly enough. Laser speckle contrast imaging (LSCI) has been demonstrated to provide the ability to visualize flow in vessels in real time and continuously without the need for contrast agents. In LSCI, the tissue of interest is illuminated with low power laser light at red or near infrared wavelengths and the light reflected from the tissue surface is imaged onto a camera. The resulting images are laser speckle patterns and a computer processes the images to produce speckle contrast images, which are images of the motion within the field of view (ie, blood flow). The purpose of this clinical investigation is to assess the usefulness and accuracy of LSCI compared to ICGA and/or FA during neurovascular surgery. LSCI videos will be recorded automatically intraoperatively in each patient before, during, and after ICGA and/or FA in the same surgical field of view to guarantee comparability of the methods.
To determine if cutting balloon angioplasty combined with DEB angioplasty provides a higher primary patency after treatment of recurrent stenoses compared with cutting balloon angioplasty or angioplasty using DEB alone in the venous outflow AVFs. For cutting balloon angioplasty in venous stenosis, the primary patency after 12 months is 55-60% (9,16) and in recurrent stenoses up to 48%(10). We hypothesise that DEB angioplasty after cutting balloon angioplasty leads to improved primary patency at 12 months.
Patients who are diagnosed with periampullary cancer will be performed pancreaticoduodenectomy with 3 types of pancreatic-jejunal anastomosis reconstructions. The investigator will analysis the complication of pancreatic fistula about: the clinical symptoms, laboratory test changing, intra-operative morphology, the risk factors
Postoperative pancreatic fistula (POPF) following pancreaticoduodenectomy is considered a life-threatening complication. This study was designed to analyze the risk factors for development of such fistula in a tertiary care center (Al-Rajhi Liver Hospital/ Assiut University).
This study is a prospective evaluation of quality-of-life after rectovaginal fistula repair at our institution
Postoperative pancreatic fistula (POPF) is a major complication and an important cause of mortality after pancreaticoduodenectomy (PD). Trans-nasal afferent loop decompression technique (TNALD) may reduce the rate of POPF based on our previous retrospective study. The aim of this open-label randomized controlled trial is to determine whether TNALD is a protective factor against the development of POPF after PD.
