Thinking About Hiatal Hernia Recurrence After Laparoscopic Repair: When Should It Be Considered a True Recurrence? A Different Point of View

Abstract

Background: High rates of recurrence after laparoscopic hiatal hernia repair have been published. Most of these recurrences are asymptomatic and only diagnosed by endoscopic or radiologic studies. The definition of hiatal hernia recurrence is still under discussion. Objective: This study aimed to define a true hiatal hernia recurrence using a score and classification criteria considering the presence of symptoms and size of the recurrence. Patients and Methods: A total of 153 patients with giant hiatal hernia larger than 10 cm in diameter underwent an operation using a laparoscopic approach. Of these patients, 129 had a complete follow-up (3–5 years) after surgery, and they were the only ones included in this study. The IT system of our hospital was our database for data registration. A score and classification were designed for definition of a “true” hiatal hernia recurrence, based on postoperative symptoms and the presence or not of a hiatal hernia in both radiologic and endoscopic evaluations. Results: Hiatal hernia recurrence based on endoscopic and/or radiologic hiatal hernia was found in 55 patients (42.6%), and only 28 of them (50.9%) had recurrent symptoms. Applying the score and proposed classification, no recurrence was considered in 18 patients (13.9%). Symptomatic and true recurrence were considered in 22.9% of patients (29 patients). Reoperation was needed for 7 patients (5.4%) because of symptomatic and radiologic recurrence. Conclusions: Postoperative symptoms, endoscopic findings, or radiologic findings are important for the definition of the type of recurrence and for the indication of appropriate treatment. The proposed score and classification are useful in order to specify the hiatal hernia recurrence and treatment.
