Abstract
Background
The aim of this prospective study was to evaluate safety and efficacy of the NiTi ColonRing™ for anastomoses on the colon or rectum.
Methods
During the period September 2008–June 2011, anastomosis using the NiTi ColonRing™ was scheduled to be performed on 60 patients (36 females, 24 males/mean aged 67 years), 53 of whom underwent colectomy for cancer and 7 reconstruction after Hartmann’s procedure. Application of the device failed in one case due to anatomical reasons. Colorectal resections performed were as follows: Right hemicolectomy (5 patients), left colectomy (2), sigmoidectomy (15) and low anterior resection (31). A follow-up clinic visit after 1 month was planned for all patients. Ten patients among the first 14 had rectosigmoidoscopy at 2–3 months. All cancer patients were scheduled for colonoscopy at 12 months.
Results
No intraoperative or postoperative bleeding related to the anastomotic technique was recorded. Median hospital stay after surgery was 10.2 days (9–22 days). One patient died on day 13 due to myocardial infarction. Clinically apparent leak was detected in one patient who had undergone reconstruction after Hartmann; the only treatment required was total parenteral nutrition for 12 days. Anastomotic stenosis occurred in another one patient who had undergone reconstruction after Hartmann; it was easily resolved by balloon dilatation. Mild complications were encountered in 23 other patients (39%). Oral feeding started after day 4. Anastomotic rings were expelled naturally within 7–17 days (mean, 9.2 days). A satisfactory anastomosis was revealed in patients examined colonoscopically at 2–3 and 12 months. Mean follow-up was 15.2 months (2–33 months).
Conclusions
NiTi ColonRing™ is reliable, safe and efficacious for large bowel anastomoses.
