Richter’s Type Recurrent Indirect Inguinal Hernia, an Extremely Rare Occurrence: A Case Report

BACKGROUND: Richter’s type recurrent indirect inguinal hernia remains to be an extremely rare entity reported scarcely. It may present with grave complications in the absence of symptoms and signs of intestinal obstruction. The aim of this study is to report a rare case of Richter’s hernia after a previously repaired indirect inguinal hernia. CASE PRESENTATION: A 31-year-old male farmer came up with complaints of colicky abdominal pain and two episodes of vomiting. He had a previous right inguinal surgery. A physical examination revealed a full abdomen with right inguinal tenderness and oblique surgical scar. Abdominal ultrasound showed a bowel segment entrapped in the deep inguinal ring of the inguinal canal. Right inguinal exploration was done, and the finding was a gangrenous Richter’s type recurrent indirect inguinal hernia. The patient was discharged and improved on the seventh post-operative day after resection and anastomosis. DISCUSSION: Richter’s hernia is a rare form of hernia that occurs when the anti-mesenteric border of the bowel is partly trapped in a tight hernial ring. Its rarity, combined with the fact that it may present in the absence of typical symptoms and signs of intestinal obstruction and local physical findings, poses a diagnostic challenge which often end up with complications like gangrenous bowel at the time of diagnosis. CONCLUSION: Richter’s hernia can occur in an extremely rare form as Richter’s type recurrent indirect inguinal hernia. A high degree of suspicion, an early referral and timely imaging on the provider's side may prevent mortality and morbidity.
