Incarcerated Richter's congenital umbilical hernia in a young male: A case report

Introduction and importance: Richter's hernia is a protrusion of a portion of the circumference of anti-mesenteric side of intestine through the fascial defect. It is a rare type of hernia and typically occurs in elderly patients. Richter's hernia could result in grave complications. The objective of the study was to describe a rare case of incarcerated Richter's congenital umbilical hernia in a 20-year-old male patient.Case presentation: A 20-year-old male presented with a complaint of intermittent crampy peri-umbilical pain of three days duration associated with non-reducible umbilical bulge and vomiting. On examination, there was 4 cm by 4 cm oval, firm, tender, non-reducible mass over the umbilical area without cough impulse. He was kept nothing per os, broad spectrum antibiotic started, consent taken & operated. A loop of the ilium which was mildly ischemic found in the hernia sac. Sac and entrapped intestine were thoroughly cleaned with warm saline and reduction and herniorrhaphy done. The client discharged on the 2nd postoperative day.Clinical discussion: There have been very few reports of Richter's congenital umbilical hernia. Richter's hernia progresses more rapidly to gangrene than other strangulated hernias however patients often have no intestinal obstruction. Raised suspicion therefore is important to take timely surgical intervention before the disease advance and complications occurred.Conclusion: Richter's hernia has subclinical symptoms and late presentation which could result in grave complications and increased mortality. The early decision for surgery has paramount importance in reducing complication and associated mortality.
