Purpose: Uncertainty with the safety of the biofragmentable anastomosis ring makes surgeons hesitate in its widespread use in intestinal surgery. This study was designed to evaluate the validity of the biofragmentable anastomosis ring as a routine anastomotic device in enterocolic surgery.
Methods: The study analyzed the nine-year experience of 632 biofragmentable anastomosis ring anastomoses performed in 617 patients: 525 (83 percent) as elective procedures and 107 (17 percent) as emergency. Three classic types of anastomosis, end-to-end (n=354), end-to-side (n=263), and side-to-side (n=15), were performed with a standard technique.
Results: Anastomotic sites included ileocolic/ileorectal in 283 patients (45 percent), colorectal in 148 (23 percent), enteroenteric in 101 (16 percent), and colocolic in 100 patients (16 percent). Anastomotic leakage with clinical relevance was observed in five patients (0.8 percent): three elective cases, and two emergency (2 colorectal anastomoses and 1 ileorectal required diversions). Among 13 instances (2.1 percent) with postoperative intestinal obstruction, only 1 required relaparotomy for closed-loop obstruction. Seven patients (1.1 percent; 4 elective cases, and 3 emergency) died postoperatively; no deaths were directly related to the biofragmentable anastomosis ring technique.
Conclusions: Our data suggest that the anastomosis using the biofragmentable anastomosis ring is a uniform and highly reliable technique even in high-risk emergency surgery. Along with its clinical validities, clinical application of the biofragmentable anastomosis ring in different types of anastomoses in enterocolic surgery is expected to be expanded with a high level of technical safety.

Article Synopsis
- The study evaluated a new stent-assisted ileal bypass method for rectal cancer patients who underwent sphincter-preserving surgery, aiming to ensure safety and practicality.
- Data was gathered from 11 patients who received the procedure, which involved placing a biofragmentable stent in the terminal ileum to support recovery and eliminate the need for a protective stoma.
- Results showed that the procedure was successful with minimal complications, offering a promising alternative for rectal cancer treatment by potentially reducing the need for additional surgeries.
Clinical application of a novel stent-assisted in situ intestinal bypass in preventing postoperative anastomotic leakage for low-mid rectal cancer: A retrospective study.

This study aimed to investigate the safety and feasibility of a novel stent-assisted in situ intestinal bypass for low-mid rectal cancer patients. Patients who were diagnosed with rectal cancer and received laparoscopic low anterior rectal resection plus a novel stent-assisted in situ intestinal bypass were respectively included from March 2022 to June 2022. Biofragmentable intestinal stent with a protective sleeve was placed in the proximal colon before anastomosis, and feces could be discharged through the protective sleeve without touching the anastomosis, which achieved an in situ bypass of feces.

BACKGROUND Three patients with stage IV esophagogastric junction cancer (EGJC) underwent extended resection to achieve a graphic/surgical R0 status (no visible remnant of viable tumor in imaging/surgical findings) and adjuvant chemotherapy from the early postoperative period. We also introduced use of our digestive reconstruction technique in these patients. CASE REPORT We used jejunal interposition for digestive reconstruction, which involved end-to-end jejunojejunostomy with a biofragmentable anastomosis ring.

Anastomotic leak following colorectal surgery can be a devastating adverse event. The ideal stapling device should be capable of rapid creation of an anastomosis with serosal apposition without the persistence of a foreign body or a foreign body reaction which potentially contribute to early anastomotic dehiscence or late anastomotic stricture. A systematic review was performed examining available data on controlled randomized and non-randomized trials assessing the NiTi compression anastomosis ring-(NiTi CAR™) (NiTi Solutions, Netanyah Israel) in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) standards.

A temporarily defunctioning stoma, while effective at reducing symptomatic anastomotic leakage after low anterior resection (LAR) of rectal cancer, and its subsequent closure, is associated with significant morbidity. Here, we devised a new tube ileostomy using a biofragmentable anastomosis ring (TIB) with no need for reversal.This is a retrospective cohort study.
