The efficacy of electrosurgery and excision in treating patients with multiple apocrine hidrocystomas.

BACKGROUND: Apocrine hidrocystomas are adenomatous cystic proliferations of the apocrine glands. They typically occur as solitary lesions, though rarely may occur as multiple lesions. Management of multiple hidrocystomas can be difficult, particularly if they are large. Surgical modalities may be required for effective therapy. OBJECTIVE: To compare the results of electrosurgery and excision in treating multiple apocrine hidrocystomas. METHODS: A 50-year-old man presented with multiple apocrine hidrocystomas ranging in size from 1 to 12 mm. The lesions were located over the periorbital skin, cheeks, and pinnae. Excision and electrodessication were utilized for therapy. At a 1-year follow-up, the patient was evaluated for recurrences and cosmetic result. RESULTS: There were no recurrences until 1 year after surgery. In the areas treated with electrodessication, no visible scars were identified. In the areas treated with excision, localized scars were observed. CONCLUSIONS: Both electrodessiation and excision are effective therapies for multiple apocrine hidrocystomas. We suggest that tumors less than 1 cm be treated with electrodessication and lesions greater than 1 cm with excision.

Laparoscopic lymph node dissection using ultrasonically activated shears: comparison with electrosurgery.

PURPOSE: To assess and compare perioperative parameters in two groups of patients treated by different laparoscopic techniques of lymph node dissection (LND) for gynecologic cancer. PATIENTS AND METHODS: Between April 1996 and March 2001, 59 consecutive women with microinvasive cervical cancer (N = 5) or clinical stage I endometrial cancer (N = 54) underwent laparoscopic LND during a primary staging procedure using an electrosurgery (ELC) or ultrasonic (US) operative technique. The two groups were compared for perioperative outcomes. Differences between the two groups were determined by the Wilcoxon's rank-sum test. RESULTS: Laparoscopic LND and other staging procedures were completed successfully in 58 women (98.3%). There were no statistically significant differences between the groups with regard to perioperative outcomes (operation time, time for LND, blood loss, hospital stay, complications), but there was a significant difference (P = 0.0008) in the number of lymph nodes harvested: a mean of 13.7 in the ELC group and 17.5 in the US group. The pathologists found that the reading of histology slides was easier after US dissections because of the greater depth of thermal injury in the lymphatic tissue in ELC group. CONCLUSION: The US operative technique ensures efficient coagulation, cutting, dissection, and grasping for laparoscopic LND in patients with cervical and endometrial cancer.

High-frequency electrosurgery using the microcomputer-controlled Erbe ICC 350 unit.

To quantitate electrosurgical and tissue variables during transurethral prostatic resection and electrovaporization, these procedures were performed in five patients using standard endoscopic equipment and the Erbe ICC 350 electrosurgical generator. Current, voltage, power, and resistance were monitored continuously. Energy transfer was quantitated during each electrode pass. Prostatic resection or electrovaporization was successful in each patient. Current, voltage, resistance, and power were similar during resection and electrovaporization, whereas energy transfer was greater during electrovaporization. Generator and tissue characteristics can now be precisely monitored and instantaneously altered during transurethral prostatic electrosurgery to minimize energy transfer to the patient while producing the desired tissue effects.

Electrosurgery smoke: hazards and protection.

Early discussion regarding smoke produced by both surgical lasers and electrosurgical machines concluded that the smoke produced by these instruments was little more than a malodorous nuisance. Animal and human studies to date, however, have suggested that this smoke is, indeed, dangerous. This smoke has been shown to be mutagenic and can contain bacteria and viruses, the HIV virus being the most notable. Furthermore, these particles are small enough to penetrate deep within the respiratory tract. In response to the concerns raised by these hazards, commercial smoke evacuation systems have been designed to greatly reduce the number of hazardous particles, as well as the noxious odor produced by electrosurgery and laser surgery. The efficacy of these systems, however, is dependent o n usage and placement close to the surgical site. This review paper presents the potential hazards of electrosurgical smoke, along with some guidelines on how to properly protect hospital staff and patients from these hazards.

Bipolar electrosurgery for benign prostatic hyperplasia: transurethral electrovaporization and resection of the prostate.

PURPOSE OF REVIEW: The gold standard for surgical treatment of benign prostatic hyperplasia continues to be transurethral resection of the prostate, which is traditionally performed using a monopolar electrocautery system resulting in the possibility of certain well-recognized complications. This has led to the development of alternative surgical procedures such as vaporization of the prostate and most recently use of bipolar systems. The advantages of bipolar electrosurgery include the ability to use isotonic saline during surgery, reduced blood loss and less heat damage to the surrounding tissue. We have reviewed some of the technical aspects of the bipolar systems as well as their clinical use. RECENT FINDINGS: Bipolar electrovaporization of the prostate (Gyrus Medical Ltd, Cardiff, Wales) has been established for a few years and some data are available suggesting that the system is safe and effective, at least in the short term. The new technique of bipolar transurethral resection of the prostate has been studied in a small number of studies with promising results. SUMMARY: Bipolar transurethral resection is a novel approach in treatment of the prostate. A real paucity of clinical data is seen regarding the outcomes with this form of surgery. Although the generator and the resecting loop are different to the monopolar system, the resection technique is very similar which may be attractive to practising urologists. The need for large multi-centre studies in effectiveness of bipolar transurethral resection of the prostate is apparent.

Clinical Trials as Topic↗

Electrosurgery by bipolar modalities.

Bipolar electrosurgery is efficient for destruction or gross removal of many benign and malignant lesions. Its technique is simple and practicable in a dermatologic office. It requires local anesthesia generally, but is nearly bloodless. Instrumentation and fine points of use are described. Contraindication of use on patients bearing cardiac pacemakers is stressed.

Treatment of multiple trichoepithelioma with electrosurgery.

Multiple trichoepithelioma are benign skin tumors that present a significant cosmetic problem in young people. We report the successful treatment of two patients with electrosurgery. Specifically, through the use of a blended current, loop and triangular electrodes were used to remove the papules flush with the facial contour. In comparison to carbon dioxide laser, this modality yields identical cosmetic results yet is less expensive and considerably more time efficient.

Use of ultra-high frequency electrosurgery (radiosurgery) for cosmetic surgical procedures.

BACKGROUND: Electrosurgery has been used for many decades in medicine. Some machines generate ultra-high frequency current waveforms (radiosurgery), which minimize collateral tissue damage. OBJECTIVE: Personal experience using radiosurgery in the performance of cosmetic surgery is related in the narrative form to offer the reader a "how we do it" perspective. CONCLUSION: Radiosurgery facilitates the performance of blepharoplasty, face lifting, hair restoration surgery, abdominoplasty, nasal reduction sculpturing of rhinophyma, and minor cosmetic procedures. Collateral heat damage is minimal allowing rapid healing and aesthetically pleasing scars.

Recurrent vulvar Buschke-Löwenstein's tumor-like condylomata acuminata and Hodgkin's disease effectively treated with recombinant interferon-alpha 2c gel as adjuvant to electrosurgery.

The local application of recombinant interferon-alpha 2c hydrogel (1 x 10(6) IU IFN-alpha 2c per g) given as an adjuvant after electrosurgery led to a complete cure of previously recalcitrant untreatable giant Buschke-Löwenstein's tumor-like condylomata acuminata of a 19-year-old patient suffering from Hodgkin's disease (stage II/II). Interferon-alpha 2c hydrogel given as adjuvant with surgery may have more direct antiproliferative and antiviral activities than immunomodulating defects. This combined topical application is an effective and safe treatment which is recommended especially in immunocompromised individuals suffering from genital HPV disease nonresponsive against systemic interferon and conventional therapy modalities.

Electrosurgery in perioperative practice.

No series looking at basics in the perioperative environment would be complete without a good look at electrosurgery. And who better to inform us than Paul Wicker, who gives us all the information and advice we need to maintain patient and staff safety whilst this potentially dangerous but essential apparatus is in use. Paul also answers some of the most common questions about diathermy and its use, and I have certainly been asked all of these myself over the past couple of years. Thanks, Paul.

A five-year audit of the treatment of extensive anogenital warts by day case electrosurgery under general anaesthesia.

A retrospective five-year audit of patients with extensive anogenital warts (AGW) treated by day case electrosurgery was undertaken to determine clearance rates and recurrence rates. Published studies using these treatment modalities are few and most involve small numbers of patients. We present a series of 213 patients. One hundred and seventy-six patients underwent single procedures, 35 underwent repeat procedures and two (1%) spontaneously cleared before surgery. The outcome was known in 137 patients. Sixty-five (57%) of the single procedures, 18 (78%) of the repeat procedures and 83 (61%, [95% confidence interval [CI] 52.4-68.8%]) of the whole sample were clear by three months. Recurrence rates were 27 (24%), six (23%) and 33 (24%, [95 CI 16.9-31.2%]) respectively. These figures appear to be consistent with published data using electrocautery and surgical/scissor excision. There was a higher prevalence of smokers (compared to general population) but there was no difference in outcome between smokers and non-smokers.

Endobronchial electrosurgery.

Endobronchial electrosurgery (EBES) with the aid of a fiberoptic bronchoscope and a diathermic snare has been performed in 14 patients with tracheal and bronchial tumors (eight with benign, one with carcinoid, and five with malignant tumors). Total eradication has been achieved in the nine patients with benign and carcinoid tumors. In some patients, EBES was supplemented with surgical removal with the biopsy forceps or laser coagulation. Electroexcision of the endobronchial portion of the tumor helped to clear the respiratory airways in three of the five patients with malignant tumors. Emergent EBES was performed in two patients with acute respiratory failure and massive hemorrhage caused by adenocystic and thyroid cancer of the trachea.

Electrosurgery and wound healing: a review of the literature.

This literature review and discussion has presented evidence that some additional research needs to be done in this area. Particular attention should be paid to control certain variables: kind and type of waveform, shape and size of electrode, and speed of the electrode through the tissue so that meaningful results may be given to the dental profession. The evaluation of the literature seems to show that when the variables are controlled, untoward results of wound healing after electrosurgery seem unwarranted.

Thermal characterization of electrosurgery.

The volumetric heating response of soft tissues to electrosurgical cutting and coagulation was studied. A series of experiments was conducted with thermistor probes embedded in a surrogate medium during controlled application of the electrosurgery current. A series of temperature profiles was obtained for various thermistor probe locations. These temperature profiles were found to be linear, exponential, or double exponential, depending upon the probe-incision distance. Temperatures next to the site of tissue destruction approached 70 degrees C, within 2 seconds of application of power. Temperature changes due to lateral heating were an order of magnitude greater than temperature changes directly under the incision. Anisotropic heat conduction was observed for muscle fibers oriented in different directions.

Effect of hemostasis and electrosurgery on the development and evolution of brain tumor surgery in the late 19th and early 20th centuries.

Hemostatic options available to the surgeon in the late 19th and early 20th centuries were limited. The surgical ligature was limited in value to the neurological surgeon because of the unique structural composition of brain tissue as well as the approaches and operating angles used in this type of surgery. In this manuscript the authors review the options available and the evolution of surgical hemostatic techniques and electrosurgery in the late 19th and early 20th centuries and the impact of these methods on the surgical management of tumors of the brain and its coverings.

Electrosurgery. Technical note.

In this paper the author reviews the development of electrosurgery in neurosurgical procedures. Particular stress is placed on bipolar coagulation and the more recent addition of bipolar cutting. Basic electric principles are discussed as well as the electrophysiological basis of coagulating and cutting currents. Neurosurgical techniques and instrumentation criteria are presented. The material is planned to provide the neurosurgeon with greater understanding of the function of the equipment and, perhaps, to improve usage.
