The Rate of Compensatory Sweating and Clinical Outcomes of Selective Thoracoscopic Sympathectomy (Ramicotomy) in Patients with Primary Palmar Hyperhidrosis

Abstract

Background: Primary hyperhidrosis is a sympathetic disorder characterized by prolonged and uncontrollable sweating. It is associated with emotional stress or psychological causes that preferably affects the axillae, palms, feet, and face. Video-assisted thoracoscopic sympathetic surgery is currently a globally recognized treatment for primary palmar hyperhidrosis (PH). However, compensatory sweating (CS) is the most prominent long-term adverse effect of thoracoscopic sympathectomy. Objectives: Here, we aim to perform selective sympathetic ramicotomy for primary palmar hyperhidrosis patients and evaluate the clinical outcomes of satisfaction, as well as the effect on the frequency, location, and severity of compensatory sweating. Methods: In this single-arm trial study, 24 sympathectomies were carried out on 12 patients with primary palmar hyperhidrosis who were candidates for bilateral thoracoscopic selective sympathectomy (ramicotomy) at Imam Khomeini Hospital. The patients’ demographic information was interviewed and followed up using telephone questionnaires in the health center one week after surgery. Then, the rates of compensatory sweating, satisfaction, and failure or recurrence were retrospectively analyzed. Results: No significant differences were observed between age, gender, weight, BMI, and compensatory sweating rates. Notwithstanding, there was a statistically significant difference in the severity of compensatory sweating with patients’ height (P = 0.016). Compensatory sweating occurred in 66.7% of the patients; 50% of the patients were mild, 16.7% of the patients were moderate, and there was no intolerable compensatory sweating or recurrence. The most incidence of compensatory sweating was on the lower back. The rate of satisfaction was 94.5 ± 7.8%. Conclusions: Selective thoracoscopic sympathectomy (ramicotomy) is an effective surgical procedure with a very high level of precision and satisfaction. This technique hence should be considered the method of choice for the treatment of primary palmar hyperhidrosis.

Robotic Sympathectomy for Hyperhidrosis

“…ETS usually leaves a patient with complications such as compensatory sweating noted in more than half of patients, while robotic sympathectomy reduces these complications [ 9 , 15 , 21 ]. A patient’s biggest doubts regarding surgery are the side effects, in particular, excessive compensatory hyperhidrosis and anhidrosis [ 21 , 22 ]. Therefore, patients in the past have opted for pharmacological treatments [ 22 ].…”
