Transrectal Vacuum Assisted Drainage: A New Method of Treating Anastomotic Leakage After Rectal Resection

ABSTRACT: Anastomotic leakage is a major and potentially mortal complication with an incidence of 10-13% after resection of the rectum. For patients showing no clinical signs of peritonitis, the traditional method has been a conservative treatment with transrectal rinsing. This treatment is often associated with a very protracted postoperative course with healing times of up to a year or more for the anastomotic leakage. Treatment with vacuum drainage (VD) is a new method primarily developed for wound therapy. The objective of this study is to investigate the effects of transrectal vacuum treatment on the healing of anastomotic leakage after rectum resection in a prospective, randomized, controlled multicentre trial in 60 patients found to develop clinically significant anastomotic leakages after elective rectal resection.

Project description:In colorectal surgery, hand suturing and stapling are routine methods for performing intestinal anastomoses, and these methods appear to be similar in terms of clinical safety. Despite several years of experience with surgical procedures as well as improvements to the medical devices, problems with disturbed anastomotic healing leading to leakage and stenosis after colorectal surgery remain a significant challenge for surgeons. A frequency of anastomotic leakage after stapling or suturing has been reported to range from 3% to 20%. In addition, preoperative radiotherapy has been shown to increase the risk of anastomotic leakage even further. The methods that are used today to detect leakages are unfortunately inaccurately and limited to monitoring symptoms, temperature, CRP-levels, and performing abdominal examinations and CT-scans. These clinical signs and parameters usually become apparent several days after onset of the leakage, which leads to a delayed diagnosis. Anastomotic leakage is not only a significant cause of increased morbidity of complications and mortality in patients, but also associated with increased risk of local recurrence and poor prognosis. Moreover, when reoperation is required to fix the leakage, a permanent stoma may be made at the level of the sigmoid colon and this procedure impacts live quality of patients negatively. Based on the above considerations, a novel, adaptive anastomotic method has been developed by CarpoNovum to achieve a safer anastomosis. The method’s working name is C-REX Ring-locking Procedure. C-REX is referred to our Colorectal anastomotic rings for Re-join the intestinal ends and validate the anastomosis, with function of Extract samples for analysis and conduct X-ray through connected catheters. The novel adaptive anastomotic medical devices, C-REX LapAid and C-REX DMH/DMHC are easy to use, with unique possibility to control the anastomosis during and after surgery. The previous successful preclinical study encourages a clinical verification in patients undergoing colonic resection to evaluate the safety and performance of C-REX Ring-locking Procedure by use of C-REX LapAid and C-REX DMH/DMHC.

The previous successful pre-market data support a successful CE marking of the devices, which encourages a post-market clinical follow-up (post CE mark clinical study) in patients undergoing colonic resection to collect post-market data of C-REX LapAid Cath and C-REX RectoAid Cath for the purpose of clinical evaluation and risk analysis.
