Diagnosis and surgical treatment of obturator hernia in the recent decade with long-term follow-up: A single center experience

Obturator hernia (OH) is a rare and dangerous disease that can lead to life-threatening consequences, and pelvic computed tomography (CT) is widely used for its diagnosis. There is no consensus regarding the surgical approach and repair methods. Retrospective analysis of the clinical and follow-up data of 15 cases of incarcerated hernias patients admitted to the Department of General Surgery, affiliated to Taicang Affiliated Hospital of Soochow University, from January 2011 to December 2022. OH could be precisely diagnosed with pelvic CT scan, except for occult OH and non-strangulated OH. Thirteen patients underwent emergency surgery, with a total complication rate of 76.9% and no mortality. Ten patients underwent open surgery, and 3 patients underwent laparoscopic surgery, which had advantages in terms of total cost and postoperative hospital stay (P < .05). Emergency patients all underwent simple peritoneal closure, and hernial sac excision was simultaneously performed in 6 of them. A recurrence (7.7%) was detected at 38 months after the first operation. There was no statistically significant difference between the 2 tissue repair methods in terms of recurrent rate. Pelvic CT can be used as a gold standard for the diagnosis of incarcerated OH, but it has limited value in occult OH and non-strangulated OH. Laparoscopic surgery is recommended for patients with a short onset time and no abdominal physical signs. Tissue repair is sufficient for incarcerated OH and hernial sac excision may be unnecessary.
