Role of laryngopharyngeal reflux (LPR) in complications after tonsillectomy in adult patients

Tonsillectomy and tonsillectomy with adenoidectomy are among the most common surgical procedures in otolaryngology practice, but the complications, especially the postoperative bleeding, are seriously troubling surgeons. Some authors had identified that gastroesophageal reflux and LPR are both risk factors for complications in tonsillectomy of children patients.Therefore, we designed this prospective study to assess the role of LPR in the development of complications following tonsillectomy in adult patients. We want to provide a basis for future clinical practice.We recruited a totally of 150 adult patients (18-60 years old) who had an indication of tonsillectomy because of recurrent tonsillitis and divided them into two groups, the laryngopharyngeal reflux (LPR) group and the control group identified by the results of Reflux Symptom Index (RSI) and Reflux Finding Score (RFS). The complications that were observed and evaluated were pain, hemorrhage, fever, infection, and pulmonary problems.All the patients complained of pain after surgery. The duration of the pain in the LPR group was much longer than that of the control group. In the LPR group, patients had a similar pain level on the first day after surgery. However, on the 7th day and 14th day after surgery, the pain level was obviously higher than that of the control group. We found that the body temperature mildly rose on the 1st day after surgery and gradually fell to normal level in both groups. No cases had bleeding within 24 h after surgery. There were nine cases of bleeding in the LPR group, while only one case of bleeding occurred in the control group. There were no cases of infection or pulmonary complications in either group.LPR is closely related to the complications followed by tonsillectomy and we also suggest that high dosages of proton pump inhibitors (PPI), alkaline water, and alginates should be prescribed to the patients with LPR during the perioperative period.
