Dr. Reisfeld Performing Surgery

Dr. Reisfeld, one of the worlds top hyperhidrosis surgeons.This page describes the most effective types of surgery depending on the location and severity of a patient’s hyperhidrosis. Dr. Reisfeld is the only surgeon in the world to be an expert at all three major procedures listed below. This gives him unparalleled expertise in performing these procedures.

  1. For those who suffer primarily from severe and excessive hand sweating (palmar hyperhidrosis) then endoscopic thoracic sympathectomy is most appropriate.Learn more about Endoscopic Thoracic Sympathectomy (ETS)
  2. For those who suffer from severe excessive foot sweating (plantar hyperhidrosis) as their primary or only area of excessive sweating or for those patients who did not get any benefit from endoscopic thoracic sympathectomy for their foot sweating then endoscopic lumbar sympathectomy is an appropriate procedure.Learn more about Endoscopic Lumbar Sympathectomy (ELS)
  3. For those patients suffering from excessive armpit sweating (axillary hyperhidrosis) the current method is a combination of subdermal laser ablation of sweat glands and as well as axillary suction currettage. This method combines the benefits of the two most used procedures.
    • Patients who suffer from excessive hand sweating as well as armpit sweating can benefit from a slightly modified ETS approach.

  4. Even though ETS and ELS are very effective in treating hyperhidrosis in specific areas these surgeries cannot be performed at the same time. At least 4 months should be allowed between each surgery. This time allows the body to adjust to physiological changes. It is up to the doctor and patient to determine which surgery is most appropriate for the patient.

Advantages of hand sweating procedure (ETS)

  • ETS is the only procedure available that provides a permanent solution to excessive hand sweating (palmar hyperhidrosis).
  • The procedure is proven to be safe and effective.
  • This procedure has a 98-99% success rate.
  • Dr. Reisfeld is highly experienced, performing the procedure on almost a daily basis.
  • Patients are able to leave the same day of the procedure.
  • Patients are able to return to their normal daily routine within a short time.

Details of the surgery (ETS – Endoscopic Thoracic Sympathectomy):

  • The procedure itself is done on an outpatient basis. The patient returns home or to their hotel the same morning.
  • The operation is done under general anesthesia. Two very small incisions are made on either side.
  • Air is inserted through the incision into the chest cavity. The reason for the air is to push the lung away from the operative site. At no time does the lung collapse because we use single lumen intubation. This means that air is exchanged through both lungs throughout the entire procedure. Different ETS surgeons use different techniques including the use of double lumen endotracheal tubes, which in turn, leads to a collapsed lung. Even with a collapsed lung, however, the lung will go back to its normal position once it is inflated again.

  • Endoscopic equipment (a fiber optic camera and a working instrument) is then inserted. Two high-resolution monitors are placed at either side of the patient so the doctor has a perfect view of the custom-made instruments he is using.
  • The sympathetic chain is located along the rib’s head.
  • The endoscopic instruments are used to clamp the T3 to T4 segment of the sympathetic nerve node responsible for the cause of excessive sweating. Four titanium clips are placed on each side of the nerve chain. In cases of severely associated armpit sweating clips are applied on the T5 level.The theoretical basis for this idea is the fact that most of the sympathetic innervation to the head area originates at a T2 level. Leaving this segment intact, renders more body surface (upper body) with sympathetic innervation which results in less compensatory sweating. In 2006 Dr. Reisfeld completed an important clinical study on patients and showing that the number of patients with severe compensatory sweating was reduced when the procedure was done at the T3-T4 level compared to the T2-T3 level. At the present time, for patients with the typical presentation of sweaty hands, sweaty feet, and armpit sweating, Dr. Reisfeld is doing the sympathectomy on the segment between the 3rd and the 4th rib. More clinical studies and research will need to be done to prove this further but Dr. Reisfeld is very pleased with the findings so far.
  • Once the surgery is completed, the air is taken out and the lung returns to its normal position. The instruments are carefully removed.
  • The incision is then sutured internally with absorbent sutures. This eliminates the necessity for sutures removal.
  • The process is then repeated on the other side of the chest.
  • At the present time, clamping is the procedure of choice and the one recommended by Dr. Reisfeld. The primary reason for using the clamping procedure is that it leaves the possibility for easier reversal. Easier technically and physiologically. In the cutting method, when a patient is unhappy with the results of the procedure a reversal may be done by performing a nerve graft operation. This procedure is much more involved and time consuming as compared to clamp removal. In the clamping method, reversal is much easier because it simply requires removal of the clips and by doing so gives the nerve segment a possibility for regeneration. It has been shown that some patients having the clamps removed showed lessening of the compensatory sweating (compensatory hydrosis or reflex sweating) to total disappearance of the compensatory sweating.
  • Patients who have an equal problem with the severity of their sweating in the hands and armpit area will benefit from the endoscopic thoracic sympathectomy on levels T3-T4-T5. In other words for those patients who explain that their excessive hand sweating is equal to their excessive armpit sweating adding sympathectomy at the T5 level will give them a higher chance of slowing down or eliminating their armpit problem as well. On the other hand if patients only have excessive armpit sweating Dr. Reisfeld’s current opinion is that sympathectomy should not be done for isolated armpit sweating only.

    What happens to the rest of the sympathetic chain?
    There is tremendous overlap in function within the sympathetic chain, so there are no known long-term side effects.

    Do you collapse the lungs during surgery?
    No, Dr. Reisfeld uses the single lumen intubation method which allows air to go in and out of the lungs at all times. Those surgeons that are using the double lumen technique the lung on the operated side is being collapsed.

  • Dr. Reisfeld has performed dozens of clamp removal procedures. The results are not 100% but about 50% of those cases showed improvements in their clinical condition which translated into reduction of compensatory sweating, better exercise tolerance, re-appearance of sweat in the hands and upper body, etc. Obviously more time is needed to come to any definite conclusions and also we will need more cases so statistical analysis can be made.
  • Most patients are able to walk out of the medical center within 2 hours after surgery. Regular physical activity and returning to work are possible in one week or less. Scarring is minimal as the incisions are small and well hidden in the folds of skin of the armpit.
  • Dr. Reisfeld personally checks up with each of his patients post surgery to ensure they are perfectly taken care of and to answer any and all of their questions. Dr. Reisfeld takes pride in his excellent patient care; this is very evident by reading any of the patient testimonials.

    Lumbar Sympathectomy – For Excessive Foot Sweating:

    This particular procedure was added to the variety of surgical treatments for focal hyperhidrosis since about 2006. Pioneering work was done in Brazil, Austria and France and it showed that lumbar sympathectomy could be done efficiently safely and successfully for those patients with excessive plantar hyperhidrosis (foot sweating).

    Lumbar Diagram

    Lumbarectomy: Anatomical drawing showing where the incisions are made.

    In this procedure access is made to the sympathetic chain that runs along the lumbar vertebrae. The operation is done under general anesthesia and takes about 1 to 2 hours. Patients typically go home/hotel the same day however in rare instances some patients stay at the hospital for one night and then go home the next day.

    If the operation starts early in the morning and the anatomical relations are displayed easily and nicely, the resultant pain and discomfort can be brought down to a minimum enabling the patient to leave the medical facility 2-3 hours later. Typically patients can return to normal activities such as work within a few days.

    In rare cases the patient’s anatomy may be more difficult so the operation may take a little longer. It should be re-emphasized again that because this is a more involved operation and some patients may need a slightly longer stay at the medical facility. Dr. Reisfeld is always cautious to ensure the patients safety and well-being so travel plans may be adjusted accordingly. With the experience accumulated since about 2007 it became obvious that athletes, with very developed lumbar area muscles, the sympathetic chain might be buried between or underneath the muscle. It takes a lot of knowledge of the anatomy and experience to overcome this particular finding.

    The operation is done endoscopically. In this approach there are three small cuts made on the side of the abdomen (flank region). And through those cuts endoscopic equipment is inserted, a space behind the stomach is developed and then the sympathetic chain running along the lumbar vertebrae is located. The sympathetic chain is then clamped below the level of the second lumbar vertebra. It is important to be at that level to reduce the chances of side effects. The exact location is checked with the help of X-Rays during the operation. In extremely rare cases there may be a necessity to convert the operation from an endoscopic approach to an open approach and the only difference is that one of the incisions is slightly longer. The amount of pain and the time spent at the hospital are the same. Among the reasons that sometimes necessitate conversion to an open approach are obesity, anatomical variations and safety. The operation has about a 98% success rate and it can help those patients where plantar hyperhidrosis is a major problem.

    Treatment for Excessive Armpit Sweating:

  • In isolated cases excessive armpit sweating can cause substantial discomfort, embarrassment and problems socially. There is a lot of medical options such as aluminum chloride lotions or antiperspirants with many varieties on the market (over the counter or prescribed). Botox also exists as a potential treatment to control armpit sweating but it is costly and temporary. Multiple surgical approaches were described from excision of the skin in the armpit area to a less invasive procedures where the inner layer of the armpit area skin is curated. Varying degrees of success have been noted. Laser ablation or energy applied to the armpit or ultra sound ablation were described with somewhat inconsistent results.The opinion held by Dr. Reisfeld is that the axillary suction curretage has better long term results but it should be known that even in the best of hands variations in results can happen.
  • The procedure is short and results in a minimal amount of pain. Some swelling and discomfort are to be anticipated but those are temporary.To learn more about how this life changing procedure could possibly help you please contact us.

    It is important to note that patients should always try conservative methods and consult with their doctors before embarking on a surgical approach.

    Groin Sweating:

    For those patients who suffer primarily from groin sweating visit our groin sweating page to learn about the options available.


    Can I do the operation if I have scoliosis?
    Yes, but we would need to know the degree of scoliosis. In experienced hands this anatomical variation can be handled. But experience is needed to locate the nerve which could slightly be off the regular course.

    I have a problem of hyperhidrosis in my armpits. How much it will take cost to get ETS surgery. Thanks

    • Center For Hyperhidrosis  March 14, 2015

      Thanks for the comment. Costs will be discussed with the office staff after a medical evaluation in person or over the phone with Dr. Reisfeld determines if there is a need for surgery.

    I had ETS surgery in 2006 to treat excessive sweating in my underarms and hands. After reading your surgery details, it mentions there’s a surgical option for foot sweating.

    Although my ETS surgery treated my hand sweating 100%, I am still experiencing mild underarm sweating and extreme secondary hyperhidrosis. In addition to my feet, I sweat profusely on my back and abdomen. I also experience lower body sweating including my butt and groin area.

    Do you have any recommendations on what I can do to treat the secondary sweating? I’d like to consider the lumbar sympathectomy, but I fear that I’d be sweating constantly considering my results from ETS. Any guidance is appreciated.


    • Center For Hyperhidrosis  March 9, 2015

      The compensatory sweating is a side effect that all patients who had ETS for Palmar hyperhidrosis get. The majority of the patients (up to 95%) get it on a mild to moderate fashion and they are very happy with the results. Between 3-5% of the patients get the compensatory sweating on a higher level which will leave them some what unhappy. The actual end results of the c/s are multi factorial and depend on the surgical method,body built,temperature and other factors. The Lumbar sympathectomy addresses the issue of feet excessive sweating which was not corrected by the ETS. You might get some help with the buttocks sweating after ELS. I know that it is some what complicated to explain or understand so the best way is to call us at 310 557 3037 to have a full discussion with Dr. Reisfeld. Thanks.

    Hi, I suffer from excessive hand sweating i have had this problem for as long as i can remember. I am currently enrolled in massage school and working hands on with others is difficult for me at times. It has become a problem socially for me as well always has, no matter the weather. it gets so bad that the pads of my fingers swell and the sweat drips down my hand. I just would really like to know what do i do from here. i have seen an endocrin before they thought maybe it was thyroid related, that wasnt the case. so i went to a dermatologist and they didnt even see me they suggested botox, but with what i want to do as a caree i dont know the effects it will have on my hands. so please what should i do. feel free to email me or simply reply. thanks so much

    • Center For Hyperhidrosis  March 9, 2015

      What you are describing is a typical case of primary/focal hyperhidrosis. This is a genetic disorder. In the severe cases like yours conservative treatment modalities are not helpful but should be tried(not Botox). If those fail than ETS is the best choice. You can call us at 310 557 3037 so I can answer all of your questions. Thanks

    Good Morning.
    Could having hyperparathyroidism cause the excess sweating of the neck,facial and forehead? I am on many medications but these areas are the only areas I have trouble with. I do have fibromyalgia and degenerative joint disease, having had both knees replaced. This is very fatiguing. It occurs with any type of motion, getting up from a chair, walking, bending over, and any type of house work.
    I have had many blood tests including thyroid and glucose-all negative.
    Thank You for reading my message.

    • Center For Hyperhidrosis  November 22, 2014

      Hyperparathyroidism can cause excessive sweating in the areas you mentioned. Are your parathormones within normal range? If they are not you might have a problem with your parathyroid glands and attention should be given to that. It is not so infrequent to have it but also you can read more about this on our older age body sweating page.
