181 Lessons Learned from Complex Abdominal Wall Reconstruction for the Management of Giant Paraoesophageal Hernia - a Case Analysis

Abstract

Abstract Aim In this case report, we present a new method in the management of a giant hiatus hernia: the use of crural relaxing incisions. This new method in combination with previously known strategies including botox and preoperative optimisation for surgery with weight loss and prehabiliation can result in a more effective surgical hiatus hernia repair and subsequently lead to a reduced risk of hiatus hernia recurrence. Case Presentation 71yo man admitted to hospital with a one-week history of generalised abdominal pain, nausea, vomiting and chest pain. He had a background of a known large hiatus hernia for the last 10 years. An abdominal CT showed a large type IV hiatus hernia containing the stomach, transverse colon, pancreatic body, and pancreatic neck. CT guided botulinum toxin A injections were given by interventional radiology during which the muscle bellies of the transversus abdominus, internal and external obliques were targeted. The patient was placed on a meal replacement (Optifast) diet. A laparoscopic thoraco-abdominal hiatus repair was performed finding a giant hiatus hernia containing the entire stomach, first part of the duodenum, left lobe of liver, transverse colon, small bowel and distal pancreas. Due to the size of the hiatus hernia and the potential tension likely to result from a repair, both right and left crural relaxing incisions were made to facilitate closure. Crural closure was reinforced with a Bio A mesh secured in a C configuration covering the right crural relaxing incision. The patient recovered well postoperatively. Follow up imaging did now show recurrence.
