[Evaluation of the results of surgical treatment of granuloma teleangiectodes].

In the clinic of dermatological surgery, I Department of Dermatology Silesian Medical Academy in Katowice 328 patients were treated surgically for granuloma teleangiectodes in the years 1973-1988. Two methods were used: excision of the lesion and curettage with electrocoagulation of the base of the lesion. After excision the wound was closed by approximation of its margins or local plastic procedure (285 cases) and by covering it with a free full-thickness skin graft (3 cases). Curettage and electrocoagulation was used in 43 cases, mainly due to the location of the lesion (in 90% on fingers). After granuloma excision no recurrences were observed, while after curettage and electrocoagulation recurrences developed in 20% of cases.

[Endoscopic hemostasis against hemorrhage from the upper gastrointestinal tract: its indication and limitation].

We reviewed endoscopic hemostasis that had been performed upon 353 acutely hemorrhagic peptic ulcer cases: Among them, 145 received thrombin spraying; 36, electrocoagulation; 145, topical injection of ethanol; and 27, topical injection of aetoxyscrelol. Hemostasis lasting for more than 24 hours after the treatment was defined as transient hemostasis, and hemostasis lasting for more than two weeks, as permanent hemostasis. The overall rate of transient hemostasis was 87.5%; 84.8% by thrombin spraying, 83.4% by electrocoagulation, 89.0% by injection of ethanol, 100% by injection of aetoxyscrelol, respectively. The overall rate of permanent hemostasis was 71.1%; 75.9% by thrombin spraying, 58.3% by electrocoagulation, 69.7% by injection of ethanol, 70.4% by injection of aetoxyscrelol, respectively. The rate of emergency operation for bleeding was reduced to 9.9% after the induction of endoscopic hemostasis from 64.0% before the induction. The mortality was also reduced to 3.1% from 8.9%. Particularly, over the last 4 years, the emergency operation and the mortality have been reduced, accounting from 7.2% and 2.2%, respectively. In conclusions, thrombin spraying is the first choice for mild and diffuse hemorrhage, and topical injection of ethanol is indicated for hemorrhage from exposed vessels and for localized hemorrhage.

[Endovascular electrosurgery of varicocele].

A new method of treatment of varicocele is described consisting in the endovascular electrocoagulation of the internal testicular vein in order to interrupt reno-testicular reflux resulting from insufficiency of the internal testicular vein valves. The endovascular electrocoagulation of the internal testicular vein was fulfilled via either a retrograde or an antegrade access. The endovascular electrocoagulation of the internal testicular vein was made in 49 patients with a left-side varicocele. In 38 of them coagulation was performed via a retrograde access, in 11 patients an antegrade access was used. The method is less traumatic and possesses both a diagnostic and curative value.

Endoscopic argon plasma coagulation (APC) first clinical experiences in flexible endoscopy.

Argon plasma coagulation (APC) is a new mode of non-contact electrocoagulation in which current is applied to tissues by means of ionised argon gas (argon plasma). In open surgery, APC is used for the haemostasis of superficial, diffuse haemorrhages from parenchymatous organs and for the devitalization of various tissues. Experimental studies have shown the superiority of APC to standard electrocoagulation modes and surgical techniques due to its efficiency and limited tissue traumatisation. After developing and designing special probes which can be applied through flexible endoscopes and after testing these in in vitro studies, we have been able to utilise APC in both the gastrointestinal tract and the tracheobronchial system. From June, 1991 to September, 1992, 102 patients were treated endoscopically in 189 sessions with APC in the upper and lower gastrointestinal tract as well as in the respiratory system. The indications were malignant and benign tumours, diffuse haemorrhages of various origins and sites, tissue overgrowth after stent implantation, tissue remnants after endoscopic adenomectomy, and the conditioning of fistulas prior to fibrin sealing. In all cases, APC in flexible endoscopy was highly effective and easy to perform, with advantages over standard electrocoagulation. No problems or complications were observed. The limited depth of tissue coagulation (2-3 mm) with concomitant, efficient tissue coagulation allows application even in critical areas where there is risk of perforation, such as the duodenum or colon. For many indications, APC has replaced the Nd:YAG-laser, which was formerly used widely in our unit, Except for vaporisation of extended tumours, the APC shows remarkable advantages in nearly all applications.(ABSTRACT TRUNCATED AT 250 WORDS)

[Sterilization of women in Denmark in 1990].

Investigation of the techniques employed in sterilization of women in Denmark in 1990 was undertaken and compared to an equivalent investigation done in 1985. A questionnaire was sent to all hospitals in Denmark, Greenland and the Faroe Islands. Among the departments returning the questionnaire and carrying out sterilization of women in 1990, 29 departments were specialized gynaecological departments, 31 were non-subspecialized surgical departments and five were medical/surgical departments. Laparoscopic sterilization was used in every specialized gynaecological department. The percentage of surgical departments using this method has increased from 41.3 in 1985 to 87.0 in 1990. In 1990, bipolar electrocoagulation and clip-technique were the most frequently employed laparoscopic methods. In 1985 it was bipolar electrocoagulation. Five departments are still using unipolar electrocoagulation. In 1990, hysteroscopy mainly took place in the western part of Denmark.

Bladder and bowel injury after electrodesiccation with Kleppinger bipolar forceps. A clinicopathologic study.

To evaluate the extent of electrocoagulation damage in tissue undergoing bipolar desiccation, five mature female pigs were used as models of tissue and adjacent vital structures commonly encountered during operative laparoscopy. Electrocoagulation was performed on bowel mesentery, sidewall peritoneum, ureters, uterus, uterotubal junction and broad ligament; superficial bowel and bladder burns were treated. Kleppinger forceps were also used to coagulate various-sized arteries to determine hemostasis. Histopathologic analysis demonstrated no inflammation or tissue destruction beyond the desiccated area seen immediately after coagulation and no direct correlation between tissue thickness and spread of electrocoagulation. It also appears that blood vessel hemostasis can be achieved safely with Kleppinger forceps on vessels up to 3 mm in diameter.

[Our experience with diathermy coagulation as a form of therapeutic endoscopy in acute upper digestive tract hemorrhages].

In addition to sclerosifying by use of fibroendoscope which acts upon the source of bleeding, to achieve hemostasis and prevent bleeding relapses nowadays other methods have also gained acceptance. Major importance among these is attached to diathermocoagulation. It may principally be assumed that diathermocoagulation is indicated for critically ill patients with serious accompanying diseases of primary or secondary importance, as well as in the event of persistent bleeding during the clinical examination and impending resumption of bleeding soon after the examination. Hemostasis by electrocoagulation should not be attempted in patients in agonal state when endoscopic examination is in its self dangerous. It is contraindicated also when the source of bleeding can not be established, in cases of severe arterial bleeding, blurring the optics, and in severe concave ulcers carrying the risk of perforation. The method was applied on 173 patients; in 96 (55 per cent) electrocoagulation was successful and in 78 (45 per cent) was unsuccessful. Electrocoagulation was considered a success in patients with acute ulcers and cardiovascular disease, in cases of large erosive units of drug origin, in posteriorly located gastric ulcers, in Mallory-Weiss syndrome and in gastric cancer.

Techniques for pelvic surgery in subfertility.

BACKGROUND: Since the introduction of in-vitro fertilisation (IVF) tubal surgery has been less frequently undertaken as a technique to improve fertility in women with damaged fallopian tubes. There are various surgical techniques that can be used to repair blocked or damaged fallopian tubes. OBJECTIVES: To evaluate the role of tubal surgery in the management of tubal infertility and to evaluate surgical techniques for the treatment of tubal infertility. SEARCH STRATEGY: This review has drawn on the search strategy developed for the Menstrual Disorders and Subfertility Group. We identified relevant trials from the Cochrane Menstrual Disorders and Subfertility Group Specialised Register (searched up to July 2005) and Cochrane Central Register of Controlled Trials (CENTRAL). The following databases were searched using the OVID platform: 1. MEDLINE (1966 to July 2005); 2. EMBASE (1980 to July 2005). SELECTION CRITERIA: All randomised controlled trials investigating the following topics on infertility surgery technique as follows were included.1) The role of infertility surgery versus no treatment.2) The role of infertility surgery versus alternative treatments.3) The role of magnification.4) The role of the CO2 laser at infertility surgery. 5) The role of operative laparoscopy to perform infertility surgery. 6) Any other intervention regarding surgical technique investigated by RCT. DATA COLLECTION AND ANALYSIS: Data were extracted independently by the first two authors. Differences of opinion were recognised and resolved by consensus. Two by two tables were generated for each trial for the dichotomous outcome of pregnancy and the effects on pregnancy rate of each study is expressed as an odds ratio with 95% confidence intervals. MAIN RESULTS: Seven randomised control trials were identified. No RCTs comparing infertility surgery versus no treatment or alternative treatments were found. There was no RCT found investigating the use of magnification for tubal surgery. There was no evidence for or against the use of a CO2 laser compared with standard techniques for adhesiolysis (OR for pregnancy 1.07, 95% CI 0.40 to 2.87) or salpingostomy (OR for pregnancy 1.38, 95% CI 0.47 to 4.05) from two RCTs. One RCT randomised women for salpingostomatolysis by laparotomy and laparoscopy using the classic approach or the one suture technique. There was no evidence of benefit or disadvantage when laparoscopy was compared to laparotomy. The OR for bilateral tubal patency was 1.32 (95% CI 0.55 to 3.22) and unilateral tubal patency OR was 0.82 (95% CI 0.29 to 2.29). The pregnancy rate was not reported. There was no evidence of benefit or disadvantage from two RCTs assessing the use of a prosthesis at salpingostomy compared with non-use (combined odds of pregnancy (term) in group using the prosthesis as compared to the control (OR for pregnancy at term 1.17, 95% CI 0.47 to 2.93). There was no evidence of benefit or disadvantage difference in one RCT comparing Cuff versus Bruhat technique for salpingostomy One RCT compared two methods of salpingostomy (OR for pregnancy rate ( intrauterine) 1.02, 95% CI 0.22 to 4.61). One RCT showed no evidence of benefit or disadvantage for the use of thermocoagulation or electrocoagulation at adhesiolysis, odds for pregnancy rate between the two groups OR 0.87 (95% CI 0.51 to 1.46). AUTHORS' CONCLUSIONS: From these limited data there is no evidence of benefit or disadvantage of tubal surgery versus no treatment or alternative treatments. Likewise there is no evidence of advantage or disadvantage of using microsurgery over standard techniques; laparoscopic approach over laparotomy; the use of CO2 laser; or electrocoagulation over thermocoagulation. Randomised controlled trials should be undertaken to determine the role of tubal surgery versus no treatment or alternative treatments. Randomised controlled trials should be undertaken to determine the role at tubal surgery of magnification, laparoscopic approach, the use of lasers or electrocoagulation.

Percutaneous radiofrequency facet denervation in low-back and extremity pain.

The present series includes 47 patients (35 females 12 males) with an average observation time of 8 months after percutaneous lumbar facet denervation by radiofrequency electrocoagulation. All patients had static and kinetic lumbar pain; 90% of them had pain radiating into the legs. None had clinical or radiologic (radiculography and/or CT scan) evidence of a lumbar disc herniation, and all had exhausted conservative therapy. All but one had provocation of their habitual pain on arthrography of the relevant intervertebral lumbar joints and/or on intraoperative stimulation prior to electrocoagulation. 22/47 of the patients had no immediate or late beneficial effect of the electrocoagulation. Eight of the remaining 25 patients had satisfactory relief of pain at follow-up. The failures included all patients with previous multiple lumbar operations except for three.

Electrolytic treatment of an industrial wastewater from a hosiery plant.

Textile plant wastewater being treated in a facultative pond system had too high of a solids concentration to be reused in the dying and rinsing processes. Electrocoagulation was evaluated to further treat the pond effluent to remove turbidity, which was caused by dyes and microorganisms. A range of amperages were tested for removal of turbidity and chemical oxygen demand (COD). Electrocoagulation lowered the turbidity from 1400 NTU to below 50 NTU; and COD was lowered from 550 mg/L to approximately 250 mg/L, which was acceptable for reuse. In addition, a laboratory-scale sedimentation study was conducted on the electrocoagulated pond effluent, which indicated that a settling time of 35 minutes would provide for 80% removal of suspended solids, which was acceptable for reuse of the water in plant processes.

Electrosurgery for the skin.

The purposes of electrosurgery are to destroy benign and malignant lesions, control bleeding, and cut or excise tissue. The major modalities in electrosurgery are electrodesiccation, fulguration, electrocoagulation, and electrosection. Electrosurgery can be used for incisional techniques that produce full-thickness excision of nevi, for shave techniques that produce partial-thickness removal of superficial lesions, and for removing vascular lesions such as hemangiomas or pyogenic granulomas. The correct output power can be determined by starting low and increasing the power until the desired outcome is attained (destruction, coagulation, or cutting). Smaller cherry angiomas can be electrocoagulated lightly. Larger cherry angiomas may be easier to treat by shaving them first, then electrocoagulating or desiccating the base. The elevated portion of pyogenic granulomas can be shaved off with a scalpel or a loop electrode using a cutting/coagulation current. The base of the lesion is curetted to remove the remaining tissue and then electrodesiccated. Complications such as burns, shocks, and transmission of infection can be prevented by careful use of the electrosurgical equipment.

Endoscopic coagulation of sphenopalatine artery for posterior epistaxis.

OBJECTIVE: To present our experience of endoscopic electrocoagulation of sphenopalatine artery for persistent posterior epistaxis despite conservative measures. METHODS: Seven endoscopic electrocoagulation of sphenopalatine artery was done for four patients from early 2001 till the present for recalcitrant epistaxis despite conservative treatment. The basic principle of this surgical method is to identify the sphenopalatine artery via endonasal endoscopy and to electrocoagulate the vessel. RESULTS: Seven procedures were carried out in four patients. Endoscopic coagulation of sphenopalatine artery was carried out unilaterally in one patient and bilaterally in three patients. The artery was identified in all cases with successful postoperative results. CONCLUSION: This method is an effective surgical technique for persistent posterior epistaxis with low morbidity.

[Gastric antral vascular ectasia (GAVE) or watermelon stomach syndrome: report of 3 cases and clinical and therapeutic indications].

OBJECTIVE: The authors report their experience in diagnosis, treatment and ambulatorial follow up of 3 cases of obscure upper gastrointestinal bleeding by gastric antral vascular ectasia (GAVE). EXPERIMENTAL DESIGN: Complete clinical report of 3 cases. Clinical and endoscopic indication, evaluation of effectiveness of endoscopic treatment with bipolar electrocoagulation and follow-up. SETTING: Operative Unit of General and Thoracic Surgery. University "Paolo Giaccone" of Palermo. INTERVENTION: Endoscopic treatment by multiple session with bipolar electrocoagulation. No complications were registered. RESULTS: Complete recovery with "restitutio ad integrum". No relapse were recorded at follow up. CONCLUSIONS: The objective of the treatment is to recognize the site of obscure bleeding and then stop it. The choice between pharmacological, endoscopic and surgical treatment is individual for each patient. According to us, the endoscopic treatment is the first step in a gradual clinical approach, to detect the site of the lesion, to treat with bipolar electrocoagulation or with Argon Plasma Coagulator (lower wall penetration and minimal risk of perforation).

[Microsurgical technique of brain glioma---a report of 183 cases].

BACKGROUND & OBJECTIVE: Prognosis of glioma is still poor, its main treatment is surgery. The extent of tumor resection relates with prognosis. This study was to evaluate the extent of resection, post-operative Karnofsky performance scale (KPS), and survival rate of the glioma patients received microsurgery. METHODS: Records of 183 glioma patients received microneurosurgery were retrospectively analyzed, the extent of resection, post-operative KPS, and survival rate of patients were evaluated. Different microsurgical techniques were applied according to the location of gliomas. En bloc resection was performed for gliomas in non-functional areas by dissecting the tumors along edema area with high-power bipolar electrocoagulation. The tumors in functional areas were separated along cortex sulcus, the central part of tumor was removed firstly, and residual part was resected with low-power electrocoagulation. Gliomas close to important vessels were sucked, and electrocoagulation seldom performed. RESULTS: Among 183 cases of glioma, 85 in non-functional area, 47 in functional area, and 51 close to important vessels. Total and sub-total resection was performed in 163 patients (89.1%). The average post-operative KPS was 74. The KPS was decreased in 23 patients, increased in 44 patients, and stable in 116 patients. Patients were followed up for 12-216 months with an average of 47.8 months. The follow-up rate was 100%. Among 113 patients with long-term follow-up (>/=5 years), 5-year survival rates of low-grade, and high-grade astrocytoma patients were 75.4% (52/69), and 18.2% (8/44). CONCLUSION: Using different microsurgical patterns according to location of glioma, maximal resection of tumor may achieve with protection of neurological function.

[Electrosurgical technologies in hemorrhoidectomy].

Based on experience in the treatment of 156 patients with chronic haemorrhoids, a comparative study of clinical efficiency of electrosurgical techniques in hemorrhoidectomy was carried out. Device-controlled bipolar electrocoagulation is characterized by less invasiveness compared with electrosurgical closed hemorrhoidectomy. Device-controlled bipolar electrocoagulation provides better repair and treatment of wound inflammation, shorter wound healing. Long-term results of device-controlled bipolar electrocoagulation were followed-up for 12 months; a high level of life quality was achieved.

[Pre- and postoperative quantitative measures of facial sensitivity in tic douloureux].

Electrical stimulation was used for quantitative assessment of facial sensibility before, during and after percutaneous electrocoagulation of the Gasserian ganglion in 19 patients with tic douloureux. A portable stimulator was of a constant current type, which generated rectangular monophasic pulses of 0,2 ms in length and 100 Hz in frequency. The bipolar electrode consisted of saline-soaked felt discs with a surface of 1 cm2 and an interpolar distance of 1 cm. The thresholds for perception and pain were measured over six regions of each side of the face. Additionally, maximal pain tolerance was measured in the painful area and its corresponding healthy area. Shortlasting intravenous anesthesia with Brietal was given before each electrocoagulation. As soon as the patient began to react to speech, the threshold for pain was measured in the painful and the corresponding healthy area. Preoperatively, the measurements showed that the average threshold for perception was 2,5 mA and for pain 3,5 mA. The average maximal pain tolerance was 10,8 mA. There were no differences between the painful and the healthy sides. Electrocoagulations were stopped when the thresholds for pain in the trigger area had become twice as high as that on the contralateral side. The postoperative measurements showed that the average thresholds for perception and pain had doubled, measuring 4,8 and 8,0 mA, respectively. The average pain tolerance had risen from 10,8 to 22,5 mA. A marked rise of both thresholds was also seen in the ipsilateral areas adjacent to the trigger zone. There was good correlation between a heavy sensory deficit and a favourable clinical result.(ABSTRACT TRUNCATED AT 250 WORDS)

Luteal function after tubal sterilization.

The luteal function in women after tubal sterilization was evaluated and compared with a control group of women of a similar average age. Progesterone measurements and endometrial biopsies were obtained in the midluteal phase (5 to 10 days before the next menstrual period). The group of women who had been sterilized by tubal ligation or electrocoagulation had a significantly lower (P less than or equal to .001) mean midluteal progesterone level (8.5 +/- 6.0 ng/ml) than the group of women who had been sterilized by Hulka-Clemens clips (15.4 +/0 6.3 ng/ml) and the control group (17.2 +/- 4.8 ng/ml). The comparison between these 3 groups on days 19 and 20 and on days 21 and 22 gave the same statistical results. Progesterone levels were lower than 10 ng/ml in 54% of women after tubal ligation or electrocoagulation, whereas such low values were found in only 20% of women after sterilization by Hulka-Clemens clips and in 12% of the women in the control group. A retarded endometrium was observed more frequently in the women who underwent tubal ligation or electrocoagulation than in those who were sterilized by Hulka-Clemens clips. The most likely hypothesis to explain these differences is that sterilization using Hulda-Clemens clips preserves the continuity of the uteroovarian artery.

[Endoscopic argon gas coagulation--initial clinical experiences].

Argon-gas-coagulation represents a new method of contact free electrocoagulation, where RF-energy is applied to the tissue by means of ionized argon-gas. In the operative field argon-gas-coagulation has been used with success for hemostasis in several parenchymatous organs and for devitalization of various tissues. Experimental studies have shown the superiority of argon-gas-coagulation over standard electrocoagulation and surgical techniques due to its high efficiency and limited tissue traumatization. Having developed and designed special endoscopic probes and after in-vitro-studies we could utilize the method in flexible endoscopy as well. From June 1991 to September 1992, 102 patients were treated in 189 sessions with argon-gas-coagulation in the upper and lower gastrointestinal tract as well as respiratory system. The indications were: malignant and benign tumors, diffuse hemorrhages of various origins and of various sites, tissue overgrowth after stent-implantation, remaining tissue after endoscopic adenomectomy and conditioning of fistulas prior to fibrin sealing. In all cases argon-gas-coagulation in flexible endoscopy has been shown to be a very effective and easy to perform technique with advantages in comparison to standard electrocoagulation. Problems and complications have not been observed. The limited depth of tissue penetration (2-3 mm) coincident with efficient tissue coagulation allows the application even in critical areas such as the duodenum or colon. In many indications argon-gas-coagulation has replaced the former widely used Nd-YAG-laser in our unit. Except vaporisation of extended tumors, the argon-gas-coagulator shows remarkable advantages for nearly all applications.(ABSTRACT TRUNCATED AT 250 WORDS)
