A pseudo-TEP repair of an incarcerated obturator hernia.

INTRODUCTION

Obturator hernia (OH) is a rare condition and difficult to diagnose. While they account for as few as 0.073% of all hernias, mortality can be as high as 70%. The typical clinical presentation for OH is small bowel obstruction. Computed tomography is the diagnostic tool of choice. Surgical repair is mandatory in virtually all cases of OH and traditionally consists of performing an exploratory laparotomy.

PRESENTATION OF CASE

A 90-year-old female was admitted to our surgical service with signs of small bowel obstruction and a CT scan revealing incarcerated fatty tissue and small bowel within a left OH.

DISCUSSION

The role of laparoscopic surgery in the management of OH has been limited to elective repairs; most reports detail that the OH was found serendipitously during laparoscopic inguinal hernia operations or other pelvic procedures. A few reports describe the use of laparoscopy to treat OH associated with bowel obstruction in an emergency setting using a TAPP approach. A strict TEP hernia repair is not indicated for all patients with OH, and should rarely be performed in emergency situations given its limitation to assess or resect bowel if necessary. In selected cases, a formal exploratory laparoscopy that is negative for compromised bowel can be safely followed by a TEP repair using the same umbilical access as shown in our patient.

CONCLUSION

A 90-year-old female with a small bowel obstruction related to an incarcerated OH was treated effectively with an extraperitoneal laparoscopic approach.
