Filter by:Background:Fistula-in-ano is described as Bhagandara in the classics of Ayurveda, is an ancient surgical problem. It was commonly described even in the Vedic period. The description of Bhagandara, with the full text of its managements, can be gathered from the Sushruta Samhita, which is supposed to have been written in the second century B.C. Fistula-in-ano is a tubular ulcer formed around the peri-anal region. It may also be found anywhere in the perineal region. Its ramifications can extend to the lower back, subscrotal region, vagina etc. Hypothesis:In Sushruta Samhita(2nd BC) Acharya Sushruta has advocated Kshar Sutra treatment due to probability of recurrence after surgery. The present treatment modality Kshar Sutra has been found effective and as adjuvant therapy by avoiding recurrence.
Background Arteriovenous (AV) fistula is the most common vascular access for long-term hemodialysis in the end-stage renal disease (ESRD) patients. About 25% of these patients are diabetes mellitus. However, the effects of hyperglycemia on the vascular function of arteriovenous fistula are still remained unclear. Studies have shown that blood flow in the AV fistula is significantly reduced in patients with diabetes mellitus. Diabetic patients also require a longer period of time for the maturation of AV fistula, and have slightly higher complication rate than non-diabetic patients. Statins have been widely shown to mediate several important pleiotropic effects in the improvement of vascular endothelial dysfunction, attenuation of inflammatory responses, stabilization of atherosclerotic plaques, inhibition of vascular smooth muscle proliferation, and modulation of procoagulant activity and platelet function.Our experimental studies in diabetic animals demonstrate that administration of a water-soluble statin rosuvastatin significantly improves the fistula flow, vascular function and luminal dilatation of AV fistula in diabetic rats by suppression of vascular oxidative stress and inflammatory load. Study hypothesis The central hypothesis of this research project is rosuvastatin mediates pleiotropic protective effect on vascular endothelial function and suppresses the regional pro-inflammatory reaction in the vasculature, therefore administration of rosuvastatin during the perioperative period of creation of native AV fistulas in diabetic patients with ESRD may potentiate the vascular function and reduce the primary failure rate of AV fistulae.
The aim of this study is to evaluate the effect of hyperbaric oxygen therapy (HBOT) on patient suffering from residual Crohn's disease related perianal fistulas already treated with TNF alpha blockers
A study to evaluate the efficacy of SRM003 treatment versus participating sites' standard practice treatment in improving the rate of AVF maturation and use in subjects with end-stage renal disease undergoing surgery for creation of an AVF to facilitate hemodialysis access. It is hypothesized that when placed outside the blood vessel, the seeded SRM003 gelatin matrix containing endothelial cells can provide a continuous supply of multiple growth regulatory compounds to the underlying cells within the blood vessel, while being protected from the effects of blood flow in the vessel(s) or complications resulting from being in direct contact with the point of injury.
Efficacy of treatment of perianal fistula with mesenchymal stem cells and surgery
Pancreaticoduodenectomy is a surgical procedure for removing cancer in the pancreas, the bile system or the duodenum that is associated with a high rate of complications. The study wants to investigate whether a new technique to reconstruct the joint between the pancreatic gland and the short bowel can reduce the rate of severe complications after this complex surgical procedure.
Patients that have undergone pre-operative radiation for pancreatic carcinoma, that upon pathologic examination of the normal portion of the pancreatic gland that was in the radiation field showed acute and chronic changes in the pancreatic cells. The hypothesis for utilizing stereotactic radiation on pancreatic fistulae is that the treatment will decrease pancreatic secretions, thus decreasing autodigestion.
This will be a prospective, multi-center, post-market, single arm observational study to collect clinical outcome data on the use of Permacol™ Collagen Paste in the treatment of anorectal fistulas. The subjects will have baseline and day of surgery visits performed, and then subjects will return to the investigator for evaluation of defect and safety related morbidities at follow up visits scheduled at 1 month, 3 months, 6 months and 12 months post-surgery.
Anal abscess-fistula disease is of common occurrence and has a significant impact on the quality of life of affected individuals. The course of abscess-fistula disease as well as its treatment modalities may affect anal continence. The present cohort study investigates the results of anal fistula plug surgery. In particular, this study focus on the impact of anal fistula plug surgery on fistula healing, quality of life, and anal continence. Fifty patients will be included and followed up at 6 weeks and 6 months after surgery in the clinic of participating surgeons.
An arterio-venous fistula is a surgical procedure that supports access for people undergoing hemodialysis (HD) for End Stage Renal Disease (ESRD). This observational pilot study seeks to better understand the factors that contribute to the successful maturation of an arterio-venous fistula. A primary aim of this study is to see if endothelial function (the biochemical events initiated by cells lining the arteries) is associated with successful maturation. Other aims include determining if pro-inflammatory markers in the blood or evidence of gene expression are associated with successful maturation.
