The objective of this study is to determine whether the type of surgical approach (laparoscopy, laparatomy, thoracotomy) for paraesophageal hernia (PEH) repair affects post-surgical outcomes.
Prospectively collected patient demographics, pre-operative data, surgical details and complications were obtained for patients treated at the Ottawa Hospital between January 2004 and January 2012. We used the Kruskal-Wallis 1-way ANOVA to compare median length of stay (LOS), age, BMI, and operative times across the three surgical approaches. Chi-squared or Fisher’s exact tests were used to compare type of surgical booking (elective or emergency), sex, ASA score, type of hernia, previous abdominal surgery, intra-operative complications, post-operative complications and symptomatic recurrence between the treatment groups.
A total of 299 patients underwent laparoscopy (n=208), laparotomy (n=56) or thoracotomy (n=35) for paraesophageal hernia repair. The following baseline characteristic and preoperative details did not differ between the groups: sex, respiratory co-morbidities (COPD, Asthma), smoking status or DeMeester scores (p>0.05). The mean age (p<0.0001), BMI (p <0.001), and type of admission (emergency/elective) (p<0.001) differed significantly.
We found no difference in intra-operative complications. Post-operative complications measured were wound infection, leak, abscess, hemorrhage, and mortality. Of these, only wound infection was found to be statistically significant in favor of laparoscopy (laparoscopy 3%, laparotomy 13%, thoracotomy 11%; p<0.007).
The length of stay was shorter for laparoscopy (5 days) compared with laparotomy (18 days), and thoracotomy (15 days) (p <0.001). Patients undergoing laparotomy were slower to progress to a regular diet (mean=10 days) compared with the laparoscopic (5 days) and thoracotomy (6 days) groups (0.0001)
There was no difference in symptomatic recurrence across groups (p>0.05).
Minimally invasive paraesophageal repair significantly decreased post-operative wound infections. As well, these patients were discharged from hospital significantly earlier. Given these results, and the fact that symptom control was equivalent between groups, a minimally invasive approach should be considered for all patients requiring paraesophageal hernia repair.
