Abstract
Gastric dilatation-volvulus (GDV) is a common disease in large breed dogs. Its treatment involves medical management and surgical reposition of the stomach. To prevent the occurrence or recurrence of GDV, gastropexy is commonly applied. Various gastropexy techniques exist, among which incisional gastropexy (IG) is one of the most popular. Although IG is a very effective procedure, occurrences of GDV after IG have been reported. As a result, a modified incisional gastropexy (MIG) was developed to further reduce the failure of IG. This modification involves two additional simple interrupted sutures, one cranial and one caudal to the standard incisional gastropexy (SIG). A prospective biomechanical study using harvested pig tissues was performed to evaluate the acute strength of SIG and MIG. It was hypothesized that the higher acute strength would indicate a stronger gastropexy. The MIG had superior biomechanical strength compared to SIG. Meanwhile, a retrospective study of 347 dogs examined the intraoperative complications, postoperative complications, short-term follow up, and long-term follow up of SIG and MIG. There were no identified significant differences regarding complications between SIG and MIG in the retrospective study. There was no occurrence of GDV after either procedure. Considering the results of both studies, MIG may be a useful substitute for SIG to prevent GDV.
