Comparing Compensatory Sweating After Video-Assisted Thoracoscopic Sympathectomy: (T2-3) Versus (T2-4) Levels for Treating Palmar Hyperhidrosis.

INTRODUCTION

Primary hyperhidrosis is a disease that is characterized by excessive sweating beyond what is required to maintain the normal temperature of the body. Moreover, it has a great adverse effect on the life of the affected persons because of problems in their social lives. There are different modalities to treat primary hyperhidrosis, including medical and surgical treatment. However, in sympathectomy, there is still a lack of strong evidence regarding which level should be targeted to achieve maximum benefit with fewer complications.

METHODS

This prospective clinical study was conducted at the Cardiothoracic Surgery Department, Alexandria Main University Hospital, Alexandria, Egypt, from September 2021 to Jan 2022. The study involved a total of 50 eligible consecutive patients who had bilateral primary palmar hyperhidrosis managed by bilateral, bi-portal, and tubeless thoracoscopic approach with conventional general anesthesia. Group A represents 25 patients with 13 males (52%) who had sympathetic chain cutting at the level of T2-3, and group B represents 25 patients with 15 males (60%) who had sympathetic chain cutting at the level of T2-4. The effect on palmar hyperhidrosis, compensatory hyperhidrosis, and overall patient satisfaction was assessed on the Visual Analog Scale (VAS).

RESULT

Ninety-eight percent of patients in both groups showed postoperative complete dryness of the hand and improvement of their symptoms. There was a statistically significant (p<0.001) difference regarding the degree of severity of compensatory sweating post-operatively between both groups. In group A, 44% of patients had compensatory sweating, while in group B, 96% of patients had symptoms of compensatory sweating with varying degrees from 1 to 5 on a VAS-Score of five degrees.

CONCLUSION

The level of cauterization has no significant effect on palmar hyperhidrosis dryness after cutting the sympathetic chain at level (T2-3) vs. (T2-4). However, the greater the number of levels that are cauterized, which are three levels rather than two, the more severe the compensatory sweating in this study.
