2 Clinical Trials for Various Conditions
Anastomosis of intestine or other viscera currently requires open or laparoscopic surgery and is often the most difficult, time-consuming, and expensive part of many operations. We have developed a device ("Magnamosis") that may create compression anastomoses more easily, quickly, and less expensively than sutures or staples. The Magnamosis device consists of two 23-mm diameter, convex-concave, radially symmetric ring magnets encased in polycarbonate. One magnet is placed in the lumen of each viscus to be joined, the magnets self-align, and a compression anastomosis is achieved by tissue remodeling. We have completed extensive pre-clinical studies in animals and have shown that Magnamosis can be used to accomplish gastrojejunostomy, jejunojejunostomy, duodenal-colostomy, and colo-colostomy safely and effectively using available endoscopic and minimally invasive surgery techniques. We are now conducting a small first-in-human study to obtain clinical data in support of the safety and early feasibility of the Magnamosis device.
Procedure is offered today to most patients with chronic ulcerative colitis (CUC) or familial adenomatous polyposis (FAP) who are candidates for total proctocolectomy. While high rates of successful pouch surgery are reported, there is a significant long-term risk of pouch-related complications including ileo-anal anastomotic separation and stricture, pouch-perineal and pouch-vaginal fistula, pouchitis, pelvic sepsis, small bowel obstruction, and pouch dysfunction. Despite recent advances in treatment of these complications by medical and surgical means, these problems can still lead to pouch failure and pouch excision. The long-term rate of pouch excision is reported in large series to range from 5.3% to 24%. Moreover, the burden of quality of life impairment on patients with these complications is immense. Pouch excision operations are technically difficult with substantial morbidity. This study aimed to investigate the indications for pouch excision, the number of salvage operations prior to these excisions and complications of pouch excision surgeries.
