Abstract
AIM Although proximal faecal diversion is standard of care to protect patients with high-risk colorectal anastomoses against septic complications of anastomotic leakage, it is associated with significant morbidity. The Colovac device (CD) is an intraluminal bypass device intended to avoid stoma creation in patients undergoing low anterior resection. A preliminary study (SAFE-1) completed in three European centres demonstrated 100% protection of colorectal anastomoses in 15 patients, as evidenced by the absence of faeces below the CD. This phase III trial (SAFE-2) aims to evaluate the safety and effectiveness of the CD in a larger cohort of patients undergoing curative rectal cancer resection. METHODS SAFE-2 is a pivotal, multicentre, prospective, open-label, randomized, controlled trial. Patients will be randomized in a 1:1 ratio to either the CD arm or the diverting loop ileostomy arm, with a recruitment target of 342 patients. The co-primary endpoints are the occurrence of major postoperative complications within 12 months of index surgery and the effectiveness of the CD in reducing stoma creation rates. Data regarding quality of life and patient's acceptance and tolerance of the device will be collected. DISCUSSION SAFE-2 is a multicentre randomized, control trial assessing the efficacy and the safety of the CD in protecting low colorectal anastomoses created during oncological resection relative to standard diverting loop ileostomy. TRIAL REGISTRATION NCT05010850.

Abstract
BACKGROUND Diverting ileostomy and colostomy after total mesorectal excision reduces the risk of complications related to anastomotic leakages but is associated with a reduction in health-related quality of life and long-term economic consequences that are unknown. Our objective was to estimate the lifetime costs of stoma placement after rectal cancer resection in the U.S., England, and Germany. METHODS Input parameters were derived from quasi-systematic literature searches. Decision-analytic models with survival from colorectal cancer-adjusted life tables and country-specific stoma reversal proportions were created for the three countries to calculate lifetime costs. Main cost items were stoma maintenance costs and reimbursement for reversal procedures. Discounting was applied according to respective national guidelines. Sensitivity analysis was conducted to explore the impact of parameter uncertainty onto the results. RESULTS The cohort starting ages and median survival were 63 and 11.5 years for the U.S., 69 years and 8.5 years for England, and 71 and 6.5 years for Germany. Lifetime discounted stoma-related costs were $26,311, £9512, and €10,021, respectively. All three models were most sensitive to the proportion of ostomy reversal, age at baseline, and discount rate applied. CONCLUSION Conservative model-based projections suggest that stoma care leads to significant long-term costs. Efforts to reduce the number of patients who need to undergo a diverting ostomy could result in meaningful cost savings.

Abstract
Objectives Materials wrapping the bowel elicits tissue erosion gradually. We experienced several bowel wall erosions with no serious clinical consequences in our two previous animal experiments aimed at the safety and efficacy of the COLO-BT developed for intra-luminal fecal diversion. We tried to find out why the erosion is safe by investigating histologic changes of the tissue. Material and Methods Tissue slides at the COLO-BT fixing area from the subjects which had COLO-BT over three weeks acquired from our two previous animal experiments were reviewed. For the classification of the histologic change, microscopic findings were classified for six stages (from minimal change of stage 1 to severe change of stage 6). Results A total of 26 slides of 45 subjects were reviewed in this study. Five subjects (19.2%) had stage 6 histological change; three of stage 1 (11.5%), four of stage 2 (15.4%), six of stage 3 (23.1%), three of stage 4 (11.5%), and five of stage 5 (19.2%). All subjects which had a stage 6 histologic change survived. The phenomenon from which the back of the band is passed through is replaced by a relatively stable tissue layer due to fibrosis of the necrotic cells in the stage 6 histologic change. Conclusion We found that thanks to the sealing effect of the newly replaced layer, no leakage of the intestinal content occurs even if perforation by erosion develops according to this histologic tissue evaluation.

Abstract
PURPOSE Our previously published clinical studies described the short-term outcomes of a newly developed intraluminal fecal diverting device (FDD). FDD was a safe and effective substitute for a defunctioning stoma. However, the long-term efficacy and safety of this device remain unknown. We investigated the long-term outcomes of the use of the FDD as a substitute for a defunctioning stoma. METHODS We examined the medical records of patients who participated in our two previous FDD clinical studies. The main outcome was the number of patients with bowel continuity for 2 years after undergoing the FDD procedure or defunctioning stoma creation. RESULTS Between May 2015 and July 2018, 85 patients were screened for inclusion in this study. Of those, 27 patients underwent a defunctioning ileostomy after proctectomy. The remaining 58 underwent the FDD procedure after proctectomy. Seventy-two patients (ileostomy group, n = 22; FDD group, n = 50) with a follow-up duration > 24 months were included in this analysis. The mean duration of fecal diversion was significantly shorter (p < 0.001) in the FDD group (3.1 [1.6-6.1] weeks) than in the ileostomy group (16.7 [10.0-31.6] weeks). However, the rate of permanent stoma creation was not statistically different between the two groups (ileostomy and FDD groups, 13.6% [3/22] and 10.0% [5/50], respectively; p = 0.693). CONCLUSIONS The FDD procedure is a feasible substitute for a defunctioning stoma after proctectomy. Multicenter large-scaled clinical studies are required to validate our results.

Intraluminal bypass devices as an alternative to protective ostomy for prevention of colorectal anastomotic leakage: a systematic review of the literature. Colorectal Dis 2020; 22:1496-1505. [PMID: 32268451 DOI: 10.1111/codi.15055] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/07/2019] [Accepted: 03/19/2020] [Indexed: 02/08/2023]
Abstract
AIM Anastomotic leakage (AL) is the most important complication of colorectal surgery, leading to high morbidity and mortality. Protective ostomy, the current standard of care for protecting a colorectal anastomosis, has important drawbacks that require the creation of an alternative strategy. Over the past 30 years, several intraluminal bypass devices, designed to shield the anastomosis from the faecal stream, have been developed. The aim of this literature review was to create an updated overview of the devices available and their effectiveness in preventing AL, and to investigate whether they could serve as an alternative to protective ostomy in the future. METHOD A systematic review of the literature on intraluminal bypass devices used for preventing colorectal AL was performed. The MEDLINE and Cochrane Library databases were searched, and articles were marked as relevant if an intraluminal bypass device was studied in an animal or human population. RESULTS The database search yielded 24 relevant articles related to 10 intraluminal bypass devices protecting a colorectal anastomosis. These articles included experimental animal studies, preclinical (pilot) studies, as well as retrospective and prospective clinical studies. Each device was assessed with regard to surgical technique, effectiveness and device-related complications. CONCLUSION Intraluminal bypass devices show promise in preventing AL and its clinical consequences. However, there is insufficient high-level evidence to draw firm conclusions. There is a need for randomized controlled trials that directly compare these devices with the protective ostomy.

Abstract
BACKGROUND Defunctioning ostomy is commonly used to protect patients from anastomotic leakage complications after low anterior resection, but is fraught with its own deleterious effects. This first-in-human study examines the safety and preliminary efficacy of Colovac, an anastomosis protection device. The Colovac consists of a flexible bypass sheath, placed in the lumen of colon and anchored above the anastomosis using a vacuum stent. METHODS 15 patients underwent anterior resection (AR) with anastomosis protection by Colovac at 3 European centers. After 14 days, the anastomosis integrity was examined by CT scan and endoscopy. The device was then endoscopically removed. Data regarding demographics, surgical details, 30 day post-operative complications, and patient satisfaction were collected prospectively. RESULTS 15 patients (10 male) underwent laparoscopic AR with Colovac placement. Preoperative neoadjuvant therapy was administered to 54% of patients. Device placement was uneventful in all patients with a median duration of 7 min and placement was judged as easy or very easy in 93% of the cases. Patients did not report major discomfort during the 14 days. Endoscopic removal (10 min) was judged as easy or very easy in 87% of the cases. Absence of feces below the Colovac anchoring site was observed in 100% of the cases. 4 anastomotic leakages were observed (including 3 device migrations). Overall 5 patients (33%) required a planned stoma creation. At 3 months, 1 had already been closed. CONCLUSION Colovac provides a minimally invasive protection of the anastomosis during the healing process by avoiding the need for a diverting ostomy for two-thirds of patients who will not experience anastomotic complications and allowing safe conversion to the standard of care for patients requiring extended anastomotic protection. A larger study is ongoing to confirm these results.
