[Electrocoagulation--a curative method in the treatment of rectal carcinoma].

The authors analyze a group of 27 patients with carcinoma of the rectum who were treated in the authors' department in 1975-1990 by electrocoagulation. The authors emphasize the view of local treatment of rectal carcinoma in conjunction with modern findings on biological properties of this tumour and with regard to clinical results published in the world literature. The prerequisite of success of the method is high standard technical equipment of the department. The achieved results in the group of treated patients (66% five-year survival, 50% ten-year survival) despite the possible error of small numbers justify the authors' conviction that under conditions of strict selection and perfect technical equipment this method holds it place in the treatment of carcinoma of the rectum.

[Temperature-controlled bipolar electrocoagulation].

The safety of electrocoagulation for laparoscopic surgery has been greatly improved by the introduction of the bipolar coagulation technique. But complications caused by coagulation, especially by the overheated forceps, are still reported. In order to reduce those complications, a temperature controlled bicoagulation system was developed. This system allows coagulation with lower temperatures which can be kept constant during the coagulation process. In experiments with human fallopian tubes obtained by adnexectomy and rabbit uterine horns it is shown that those lower temperatures are sufficient for homogeneous coagulation. On line monitoring of the temperature during coagulation provides the surgeon with the possibility of directly controlling the actual temperature at the tip of the forceps. The temperature curves can easily be stored in order to be able to demonstrate the particular coagulation process even after years.

[Treatment of spontaneous pneumothorax by electrocoagulation via a fiberoptic bronchoscope with a hysteroscope irrigation outer sheath as a thoracoscope].

Since 1981 in Yamagata Prefectural Central Hospital, the authors performed electro-coagulation therapy for air leakage from bullae (blebs) via a rigid thoracoscope in 31 patients with spontaneous pneumothorax. Among these patients, this treatment was unsuccessful in 14 patients (45.2%) because of 5 multiple or giant bullae and 9 cases in which it was impossible to visualize the bullae in the mediastinum or because of pleural adhesion. In order to widen the visual field and increase the mobility of the thoracoscope, we employed a fiberoptic bronchoscope with a hysteroscope outer sheath used for irrigation as a flexible thoracoscope. This method makes it possible to examine both mediastinal pleura and adhesive pleural space, and to electrocoagulate bullae which cannot be visualized by a rigid thoracoscope. It was possible to visualize the blebs in all 13 cases with spontaneous pneumothorax in which this examination was attempted. This therapeutic procedure causes the patients less pain and the hospitals more economical because no new thoracoscope is necessary. This method of thoracoscopic therapy of spontaneous pneumothorax using a fiberoptic bronchoscope is more successful, effective, economical and painless than by rigid thoracoscope and should be attempted before thoracotomy.

[Blue rubber bleb nevus syndrome. 3 cases treated with a Nd:YAG laser and bipolar electrocoagulation].

This report concerns three patients with "blue rubber bleb nevus syndrome" presenting with recurrent digestive tract hemorrhage. Tuberous angiomas of the digestive tract associated with typical skin lesions as described by Bean led to diagnosis. Endoscopic coagulation with Nd:YAG laser and bipolar electrocoagulation "Bicap" of gastric and colonic angiomas was performed successfully without complication but did not avoid hemorrhagic recurrence originating from lesions located in the small bowel, as demonstrated during laparotomy in one case.

Symptomatic internal hernia of the broad ligament: a complication of electrocoagulation therapy of endometriosis.

A 31-year-old nulligravid woman had had two previous laparoscopies for endometriosis. Disease of the right broad ligament was treated by electrocoagulation at the first surgery, but pain persisted despite postoperative danazol therapy. At her second laparoscopy, a large defect of the right broad ligament was noted, but not treated. At her third operation, laparoscopic excision of endometriosis was followed by herniorrhaphy of the right broad ligament through mini-laparotomy. The potential for bowel herniation exists whenever a closed loop is present in the abdominal cavity.

[Laparoscopic sterilization. Late sequelae of endocoagulation and bipolar electrocoagulation].

A randomized investigation of bipolar electrocoagulation (BE) and endocoagulation (EK) was undertaken. The material was examined two years after the intervention with the object of revealing possible late complications. No significant differences were found between the two techniques. In the entire material, 97.4% were satisfied with the intervention performed and 1.3% had regretted sterilization. In approximately 40% pain of one sort or another related to the abdomen/genitalia and/or to menstruation occurred. The distribution among the groups was lower than in other materials. In 40% (EK) and 60% (BE) changes in menstrual bleeding occurred while 40% in both of the groups had developed one or other form of menopausal symptoms. In the BE-group, two women had intrauterine pregnancies as compared with no pregnancies in the EK-group.

[Endoscopic electrocoagulation and controlled pharmacological hypotension in the treatment of acute gastrointestinal hemorrhage].

The experience with the treatment of 602 patients with gastrointestinal bleeding before the introduction of endoscopy, and 805--with the use of endoscopy is summarized. At investigation, it was established that in 587 (72.9%) patients, the bleeding stopped, in 180 (27.1%)--it continued, and required in 93 the performance of electrocoagulation hemostasis. In 25 patients, the guided hypotension was used in the complex with the other methods of arresting the bleeding, the favourable outcome was noted in 22.

[Endoscopic bipolar circumactive electrocoagulation in acute upper gastrointestinal bleeding].

Bipolar circum-active probe (BICAP) is a new endoscopically deliverable bipolar electrocoagulator. 57 patients with acute upper gastrointestinal bleeding have been treated by the endoscopic BICAP and the value of the technique in the control of acute bleeding has been assessed. 57 patients underwent 47 qg probe applications with a mean value of 8.3 for each case. Immediate hemostasis was achieved in out of 57 cases (93%). Rebleeding after hemostasis by BICAP was noted in 4 out of 53 cases (7.5%). There were no complications related to the procedure. It is an important technique for the control of acute upper gastrointestinal bleeding.

Electrohemostasis with endoscopic electrocoagulation in upper gastrointestinal bleed.

Fifty patients who presented with upper gastrointestinal bleed were taken up for electrohemostasis with endoscopic electrocoagulation. Hemostasis was achieved in 32 patients at the first sitting, and in a second session in two of eight patients in whom it was attempted. No complications were encountered. EEC is an effective and safe method of achieving hemostasis in upper gastrointestinal bleed due to varied gastroduodenal lesions, and may help cut down the number of patients subjected to emergency surgery.

[Diagnostic problems posed by acute necrosis of the extremities after electrocoagulation of an epithelioma of the floor of the mouth].

Three weeks after electrocoagulation of an enormous epithelioma of the floor of the mouth, a 62-year-old man presented after a shower-bath with symmetrical cyanosis of the toes and fingers with painful oedema coloured by livedo reticularis of the lower third of the legs and forearms. In the hands this developed into a dry necrosis and necessitated their amputation. In the absence of biological tests and a posteriori the authors discuss the diagnosis of cryoglobulinaemia and intravascular disseminated coagulopathy; but in fact, these two syndromes produce very similar cutaneous symptoms, notably, cryofibrinogenaemias, cryofibrinogen being a degradation product of fibrin liberated in C. I. V. D.

An advanced system for electrocoagulation in neurosurgery.

The authors present a new, advanced system for electrocoagulation. In order to solve the problems connected with standard and bipolar EC machines available to date (i.e.: uneven and incostant coagulation; adhesion of tissue to the tips of the forceps, etc.), the Authors realized bipolar screened forceps with a well balanced current flow to avoid any heat dissipation. This new type of forceps are fed by a peculiar, two-step heating pattern, time dependent, that coagulates only the core of the clamped tissue.

Catheter electrocoagulation of serious cardiac arrhythmias.

During recent years, catheters (originally designed for intracardiac recording and pacing) have been used for purposes of electrocoagulation of the AV junction, accessory pathways, or ventricular tachycardia foci. The experience to date suggests that catheter ablation of the AV junction is a reasonable alternative for patients with drug-refractory supraventricular tachycardia who are deemed candidates for surgical division of the His bundle. Complete or partial success is expected in approximately 85 percent of patients, and thus significant numbers of patients may be spared the morbidity and expense of surgery. The available experience using catheter ablation for accessory pathways is limited, and thus definitive recommendations cannot be made. Early experience suggests that patients with posteroseptal accessory pathways who require surgical intervention may benefit from attempted catheter ablation. Although successful catheter ablation of ventricular tachycardia foci has been reported, technical problems relating to current endocardial mapping techniques, the demonstrated proarrhythmic effects of the shocks in animals, and the very limited clinical experience suggest that this use be considered highly experimental at present.

[Severe cyclophosphamide hemorrhagic cystitis controlled with transurethral electrocoagulation: a case report].

A case of massive cyclophosphamide hemorrhagic cystitis is presented. A 47-year-old woman with Evans syndrome was treated with a total dose of 56.6 g of cyclophosphamide for 2 years. Six months after the cessation of administration, massive hemorrhagic cystitis suddenly occurred following a common cold. Embolization of bilateral internal iliac arteries was ineffective. Therefore we performed transurethral electrocoagulation broadly for bleeding mucosa. The day after operation, bleeding from the bladder remarkably decreased and further transfusions were hardly required.

[Experimental endovascular electrocoagulation. Use of alternating current and a bipolar electrode (preliminary study) (author's transl)].

Early experimental studies have shown that it is possible to obtain vascular obliteration and clot formation using monopolar direct current electrocoagulation. There is a major risk of rupture of blood vessels if alternating current is used. Using a co-axial bipolar electrode and high frequency alternating current it was possible to obtain valid, reproducible, and safe vascular obliteration in the distal digestive tract arteries in dogs. The obliteration is due to lesions of the intima and the formation of a clot in situ.

Effect of median raphe nucleus electrocoagulation and serotonin synthesis blockade on oestrogen receptor content of rat uterus.

The number of oestrogen receptors (OR) in rat uterus changes in relation to the cyclic function of the ovary. In the dioestrus phase the OR content of rat uterus is significantly greater than in the oestrus phase. Electrocoagulation of the median raphe nucleus causing in rats increased release of gonadotrophins and consequent disturbances in the cyclic ovarian function is associated also with changes in OR content of the uterus. These changes are, however, not analogous to those observed in the normal sexual cycle. In the oestrus phase a very high accumulation of OR is found in the uterus, while in the dioestrus phase OR are barely detectable. Serotonin synthesis blockade with p-CPA, which is associated with an increase in the number of maturating and mature follicles in the ovary and dioestrus phase prolongation leads to a striking increase in the number of OR in the uterus.
