Successful one-stage laparoscopic procedure for de Garengeot hernia: A totally extraperitoneal repair-first approach

Abstract

The de Garengeot hernia is a femoral hernia in which the appendix migrates into the hernia sac. It is usually diagnosed intraoperatively due to its rarity and lack of clinical presentation typical to acute appendicitis. Although most cases need emergency operation due to incarceration, no standard procedure exists. We report the case of a 49-year-old woman who was diagnosed with a de Garangeot hernia preoperatively by contrast-enhanced computed tomography. She underwent one-stage laparoscopic surgery via a totally extraperitoneal approach followed by laparoscopic appendectomy. She recovered uneventfully and was discharged on postoperative Day 3. Generally, hernioplasty and appendectomy are required for the de Garengeot hernia treatment. Avoiding a peritoneal incision around the herniation and performing a mesh repair prior to appendectomy is expected to carry a lower infectious risk than other laparoscopic procedures. With accurate diagnosis, this procedure could be a useful modality for de Garengeot hernia.
