Endoscopic band ligation without electrosurgery: a new technique for excision of small upper-GI leiomyoma.

BACKGROUND: Leiomyoma is a relatively common submucosal tumor in the upper-GI tract. The efficacy of a new method for resection of these tumors, endoscopic band ligation, was evaluated. METHODS: The study included 59 patients with 64 small upper-GI leiomyomas arising in the muscularis propria as determined by endoscopy, EUS, and EUS-guided FNA. The distribution of the 64 leiomyomas was the following: esophageal, 50; gastric, 12; duodenal, 2. A standard endoscope with a transparent cap attached to the tip was used. The cap was placed over the lesion, maximum sustained suction was applied, and an elastic band was released around the base. Beginning 2 weeks after banding, the lesions were observed endoscopically once per week until healing was complete. RESULTS: The 50 esophageal leiomyomas sloughed completely. The mean time required for complete healing after band ligation was 3.6 weeks. Nine of the 12 gastric leiomyomas sloughed completely; the resulting ulcer defect was healed at a mean of 4.5 weeks. The other 3 lesions did not slough because they were not completely ligated. The two duodenal lesions sloughed completely after banding, and the mean time until healing of the defect was 4.5 weeks. No perforation occurred. Follow-up ranged from 16 to 31 months, during which time no recurrence was observed. CONCLUSIONS: Endoscopic band ligation is an effective and safe treatment for small upper-GI leiomyoma.

High-Frequency Electrosurgery in Minimal Access Procedures.

In open surgery preparation, dissection and hemostasis are easy to perform compared with endoscopic surgery. In open surgery, the surgeon is able to use a variety of instruments and methods, In endoscopic surgery, scalpels cannot be used and the freedom of manipulation of instruments such as scissors and forceps is limited. Hence, endoscopic surgery depends on the availability of special methods, instruments, and equipments for different endoscopic operations. High-frequency surgery offers different methods and instruments for preparation, dissection, and hemostasis for endoscopic interventions.

First clinical experience with new transurethral bipolar prostate electrosurgery resection system: controlled tissue ablation (coblation technology).

BACKGROUND AND PURPOSE: Bipolar transurethral resection of the prostate (TURP) can allow transurethral debulking of the adenoma with a lower potential for complications from systemic absorption of hypotonic irrigant. We evaluated a new bipolar double-loop resection system with a dedicated controlled ablation (Coblation) generator in this context. PATIENTS AND METHODS: In our series of 36 patients, 32 underwent transurethral bipolar loop resection, of whom 12 had prostates >50 cc (range for entire series 30-126 cc) on transrectal ultrasonography. Ten men had indwelling catheters because of urinary retention. The four other patients underwent transurethral resection of bladder tumors. After an initial learning curve of eight TURPs, some minor technical modifications were made, both to the bipolar-loop resection technique and to the hardware. The modified Vista Coblation system was subsequently evaluated by 18 other urologists in 17 other centers throughout the U.S. RESULTS: The median resected dry weight was 22 g, and the median operating-room time was 48 minutes, giving a median resection rate of approximately 1 g every 2 minutes. Two of the eight men in our learning curve required treatment for delayed bleeding problems (clot obstruction of catheter), and one of these received a blood transfusion. Transfusion was not required subsequently regardless of prostate size, even in men with larger glands. One of the patients treated for bladder tumor had a minor perforation of the posterior bladder wall, which healed with conservative management. In the multicenter experience in the U.S., there were 59 evaluable patients. The median resected weight was 23 g, and the median resection time was 55 minutes. Two men required conversion to monopolar roller coagulation for intraoperative bleeding. Most patients (80%) were discharged from hospital within 24 hours. No adverse neuromuscular stimulation occurred. CONCLUSION: This first single-center and international multicenter experience with Coblation technology for bipolar double-loop saline TURP confirms the feasibility and safety of this procedure. Subjective evaluation showed the four most important perceived benefits of bipolar over monopolar TURP to be smoother cutting action, elimination of TUR syndrome, less tissue burning (and no smell), and reduced bleeding. The results of randomized studies with this technology are awaited, while its role in bladder tumor resection remains unclear.

Electrosurgery using insulated needles: treatment of telangiectasias.

This paper deals mainly with operative techniques and clinical aspects of treating telangiectasias using insulated needles. The specialized needle is insulated at its base as well as on one half of the needle surface. The results have proven to be very satisfying, and this method shows promise not only in the treatment of superficial telangiectasias but also in deeper lesions as well.

Aborted implantable cardioverter defibrillator shock during facial electrosurgery.

A patient with a fourth-generation transvenous implantable cardioverter-defibrillator system nearly received an inappropriate defibrillation discharge while undergoing electrofulguration of keratotic facial skin lesions. The incident was confirmed by analyses of the implantable cardioverter-defibrillator's time/date stamped event log and stored electrogram record. Therapy was withheld by the noncommitted implantable cardioverter-defibrillator as the pulsed electrocautery was not continued beyond the charging period.

Electrosurgery and wound healing: an experimental study in rats.

Many surgeons are hesitant in the use of electrocautery on the gastrointestinal tract. The aim of the present study is to compare wound healing following incisions made by scalpel and diathermy in the rat. Healing was assessed by bursting strength measurements and histology. This study revealed no difference in strength by bursting measurements between scalpel and diathermy incision. Histologically there is not a lag in healing in the gastrointestinal tract following electroincision. It is concluded that in abdominal surgery, diathermy can be used without detriment to the strength of any suture line and with no difference in its final healing.

Effects of electrosurgery on the gingival attachment in rhesus monkeys.

A biometric and histometric study of electrosurgical gingival "troughing" with a fully rectified current was accomplished in four Rhesus monkeys. The operation resulted in a statistically significant recession of the free gingival margin and loss of connective tissue attachment associated with apical migration of the junctional epithelium. Burn marks from contacts with the electrodes were observed on the cemental surfaces and in the dentin under the enamel close to the cemento-enamel junction. The cemental burn marks usually were covered by epithelium, which may explain the apical migration of the junctional epithelium observed in the experiemtal teeth. A slight loss of crestal alveolar bone occurred in the experimental areas and a bone sequestrum formed in one instance. Secondary dentin was found in response to electrosurgical contact of the cemental surface.

Post-cholecystectomy wound morbidity: the influence of electrosurgery.

The wound morbidity patterns following elective cholecystectomy were reviewed in 235 patients. The method used to divide the musculo-aponeurotic layers of the abdominal wall did not influence the overall wound morbidity rate. There was, however, a disproportionate number of males with wound morbidity following an electrosurgical incision. The explanation may be related to the increased rectus muscle mass in males.

[Bipolar hysteroscopic electrosurgery done with Versapoint system: comparison to operations done with monopolar electrodes, own experience].

The aim of the paper was to compare properties of mono- and bipolar electrodes in histeroscopic surgery. The bipolar electrodes allow enriching better hemostasis, thanks of the vaporisation effect it takes less time to remove submucosal myomas. Versapoint is an alternative tool for the laser. Use of physiologic saline as the medium for uterine cavity distension is safer for patients during long-lasting histeroscopic operations.
