WTP5.3 Setting up a Complex Abdominal Wall Reconstruction Unit: Our first 12 months’ experience in a District General Hospital

Abstract

Abstract Aims Incisional hernias are distressing post-operative complications which develop in 25% of surgical incisions. We present our initial experience of setting up a Complex Abdominal Wall Reconstruction (CAWR) unit in line with international guidelines and Get It Right First Time (GIRFT) model of care. Methods A bespoke CAWR Multidisciplinary Team was established in our trust in January 2022, comprising 2 colorectal surgeons, 2 bariatric surgeons and anaesthetists (who performed the preoperative Botox injections and optimized high-risk patients). The unit had support from radiologists, the weight management service, and the orthotics department. We had approval from our governance, drugs and therapeutics team. Pathways for risk stratification, risk modification with pre-optimisation, standardised surgical techniques and post-operative care were created. Results Between January and December 2022, 8 MDT meetings held and 52 patients were discussed. The average BMI was 34 (22-50.5) All patients underwent a preoperative CT scan to delineate the anatomy of the hernia. The median size of the defect was 6 cm (range 3 to 22 cm). Open Rives-Stoppa repair was performed in 19 patients, with transversus abdominal muscle release in 6 and 3 patients had laparoscopic repair. One recurrence and 2 superficial surgical site infections were noted. 38.4% patients had BOTOX, 40.3% advised preoperative weight loss and 5.7% for bariatric surgery before hernia repair. A high-risk anaesthetic opinion was obtained in for 7.6% and 17% were deemed unfit. Conclusions Our initial experience and data highlight the feasibility of delivery of CAWR service at a non-tertiary unit in line with GIRFT principles. The initial follow-up indicates improved patient outcomes and experience.
