[Compression anastomoses with nikelid-titanium rings in peritonitis]

Area of Science:

• Surgical Innovation
• Gastrointestinal Surgery
• Medical Device Technology

Background:

• Advanced peritonitis often necessitates intestinal resections.
• Surgical complications, including anastomosis failure, are common in these high-risk patients.
• Novel techniques are needed to improve surgical outcomes.

Purpose of the Study:

• To evaluate the clinical implementation of compression anastomosis using nickel-titanium rings (NTR) with shape memory.
• To assess the safety and efficacy of NTR compression anastomosis in patients with advanced peritonitis requiring intestinal resection.

Main Methods:

• Analysis of 76 interintestinal anastomoses performed with NTR (Günter-Ziganshin implant) between 2011-2017.
• Unified technique using NTR as a 'clerical clip' for various intestinal reconstructions.
• Assessment of anastomosis adequacy via clinical observation and intraoperative findings.

Main Results:

• Mean enteroenterostomy time was 2.6±0.98 minutes.
• Anastomosis failure rate was 3% (compared to historical data).
• Macro- and microscopic analysis confirmed complete impermeability and signs of regenerative processes; implant rejection occurred at 7.8±1.4 days.

Conclusions:

• Compression anastomosis with NTR significantly reduces the risk of anastomosis failure in advanced peritonitis to 3%.
• The technique decreases surgical time, minimizing intraoperative aggression.
• This approach improves outcomes for patients with prognostically unfavorable conditions.
