ABSTRACT
PURPOSE: Inguinal hernias are the most common type of abdominal wall hernias. Although surgery is the only effective treatment for these hernias in adults, several problems associated with surgical treatment have been reported. If the hernia exits from a weak point of the abdominal wall, it can obstruct the bowel, thereby causing serious complications, including intestinal obstruction or strangulation. Through this study, we aimed to analyze the optimal incarceration induction time taken to cause some degree of necrosis from which recovery would be possible in a rat incarcerated abdominal wall hernia model and to determine the efficacy of heparin for expedite recovery from intestinal incarceration. METHODS: A rat incarcerated abdominal wall hernia model was constructed, intestinal activity and the incarceration induction time were determined based on the color of the intestine and HE staining of intestinal sections. Heparin and procaine were sprayed onto intestinal surfaces, and their effects on the recovery from intestinal incarceration were evaluated. RESULTS: Recovery from intestinal incarceration would be better if the incarceration induction time was maintained below 2.5 h in our rat model, and heparin was found to be superior to procaine in the expedite recovery from intestinal incarceration, particularly immediately after relieving such intestines. CONCLUSIONS: The results of this study are significant for planning the treatment of incarcerated inguinal hernia. Further, heparin is superior to procaine in terms of expedite recovery from intestinal incarceration.
