Routine esophageal manometry for surgical planning before laparoscopic paraesophageal hernia (PEH) has been advocated in an effort to reduce the likelihood of postoperative dysphagia. The purpose of this study is to investigate whether omitting routine preoperative esophageal manometry is associated with a change in the type of fundoplication performed and with an increase in the incidence of postoperative dysphagia. A retrospective cohort study of consecutive patients with and without preoperative esophageal manometry undergoing PEH repair was performed between January 2011 and July 2014 at an academic medical center. Demographic and outcome data were collected in a prospective database. The primary outcome measures were the type of fundoplication performed and postoperative disease-specific quality-of-life (GERD-HRQL) dysphagia score. Secondary outcome measures were total GERD-HRQL score, proton pump inhibitor (PPI) use, and requirement for endoscopic dilation. One hundred twenty-five patients underwent laparoscopic PEH repair. Forty-seven (37%) patients had preoperative manometry and 79 (63%) did not. Patients who did not have manometry were older (67.9 ± 14.3 vs. 61.7 ± 13.5, P = 0.02), but the groups did not differ in terms of BMI, gender, PPI use, baseline GERD-HRQL dysphagia score, or baseline total GERD-HRQL score. Sixty-nine (87%) patients without manometry and 43 (93%) patients with manometry underwent a complete fundoplication (P = 0.55). At a median follow-up of 16 (4-44) months, the median GERD-HRQL dysphagia scores (0(0-1) vs. 0(0-1); P = 0.66) and total GERD-HRQL scores (3(1-8) vs. 4(0-8); P = 0.72) were equivalent between the groups. Equivalent proportion of patients without and with preoperative manometry used PPI (9% vs. 21%; P = 0.06) and required endoscopic dilation (6% vs. 6%; P = 0.99) in the postoperative period. Omission of routine preoperative manometry prior to laparoscopic PEH repair is not associated with a change in the type of fundoplication performed, an increased incidence of postoperative dysphagia, or an increased requirement for postoperative endoscopic dilation.
