Secondary sympathetic chain reconstruction after endoscopic thoracic sympathicotomy.

Thoracoscopic sympathicotomy by electrocautery is an irreversible procedure. Thus the indications must be meticulously considered before the final decision to operate is taken by both the surgeon and the patient. All possible side effects should be dealt with and written informed consent required. A case of an open nerve reconstruction of the divided sympathetic chains is presented. One year after the reconstruction the patient reported subjective relief of the compensatory oversweating and restoration of sweating in the face and the armpit. Reversible methods like clipping the sympathetic chain should be considered whenever feasible instead of the irreversible electrocoagulation of the sympathetic chain.

Operative colonoscopy in cancer patients.

Gastrointestinal endoscopy has experienced tremendous developments in technology and equipment over the past decades. It is not only a diagnostic tool, but it also allows some interventional treatments in benign and malignant digestive diseases. Operative colonoscopy has been used to perform curative treatment of various kinds of polyps, flat and carpet-like adenomas and early colorectal carcinomas. Endoscopic palliative treatment strategies, such as the placement of self-expandable metal stents (SEMS), laser ablation, photodynamic therapy (PDT), argon plasma coagulation (APC), electrocoagulation, and injection therapy, have been proved to effectively alleviate advanced colorectal cancer (CRC) associated symptoms and maintain or improve the quality of the patient's remaining life.

Laparoscopically assisted subtotal colectomy.

A technique for laparoscopic total resection of the colon performed in six patients is reported. The diseased colon was separated from the mesocolon and the greater omentum by electrocoagulation and sharp dissection. The mesenteric vessels were divided using an Endo GIA stapling device (AutoSuture, France). The whole colon was removed after transection of the rectum and extraction through a right minilaparotomy. A primary stapled end-to-side ileorectal anastomosis was performed through the anus under laparoscopic guidance. This technique can be applied to cases involving a variety of benign lesions of the entire bowel or multifocal small malignant colonic neoplasms with a decrease in patient morbidity and shorter inpatient period.

Laparoscopic procedures for treatment of infertility related to polycystic ovarian syndrome.

The use of laparoscopic techniques for the treatment of polycystic ovarian syndrome (PCOS) has included many different approaches in the 1980s and 90s. Broadly similiar results have been obtained using biopsy, cauterization, multi-electrocoagulation and laser surgery; i.e. > 50% ovulation and a mean pregnancy rate of 50%. Evaluation of the data is complicated by the lack of uniformity in these clinical studies and the variation in diagnostic criteria. None of the studies included a treatment-independent control group. Endocrine changes following laparoscopy have been identified in many studies, but the mode of action of these treatments remains a mystery. In conclusion, laparoscopic techniques have the advantage over surgical wedge resection of cost saving and a lower risk of post-operative adhesions. For clomiphene resistant patients, laparoscopic techniques have many advantages over gonadotrophin therapy including serial repetitive ovulation events, no increased risk of ovarian hyperstimulation or multiple pregnancies and a lower incidence of spontaneous abortion, but these procedures must not be considered as the first line treatment for the anovulatory patient with PCOS, for whom clomiphene citrate remains the first choice mode of therapy.

Cost effective management of heavy uterine bleeding: ablative methods versus hysterectomy.

The treatment of menorrhagia in the twentieth century changed after 1960 with the introduction of hormonal therapy as well as an array of laboratory, imaging and minimal access tests for more accurate diagnosis. Since 1981, hysteroscopy has been used for diagnosis as well as the control of thermoablative treatments of bleeding non-malignant endometrium, including laser, electrocoagulation and electroresection. The success rates, complications, intermediate range outcome and cost comparisons with hysterectomy favor hysteroscopic methods. But the long term data on both hysteroscopic ablation and hysterectomy are not yet complete. In an effort to simplify techniques, reduce costs, and reduce complications, a variety of non-hysteroscopic methods and devices have appeared. Only two balloon devices have satisfactory success data as well as sufficient field experience to provide some degree of reliability regarding complications, which appear to be very low. Most of the devices have had clinical trials, which suggest equivalence to hysteroscopic endometrial ablation, but the determination of clinical safety requires at least several thousand cases. However, the levels of effectiveness for most of these devices make them candidates for commercial use. Hysterectomy may move from a primary surgical treatment of menorrhagia to a second-line treatment after ablation, particularly if some of the non-hysteroscopic methods become well accepted. If they are found to be safe, the costs and ease of use for the gynecologist and patient will make them attractive as a first-line surgical option. Hysterectomy, whether abdominal, vaginal, or laparoscopic will then be applied to ablation failures or non-candidates. This has the potential to change gynecological training and practice significantly in the future.

Sterilization by laparoscopy.

Today, female sterilization is most easily accomplished by single-puncture laparoscopy and, ideally, is carried out under local anesthesia. In experienced hands, electrocoagulation offers slightly fewer failures if a large portion of tube or two segments are destroyed. Fulguration of a small portion of tube, bands, or clips offer a better chance of reversal. It is extremely important that the operator be familiar with and use proper equipment, along with following a rigid format, if complications are to be kept to a minimum. The underlying theme for this article, and all of the articles published, shows that, regardless of the method employed to interrupt the tubes, the complication and failure rates are usually more a function of the experience of the operator than of the method employed.

Endoscopic treatment of Dieulafoy hemorrhage.

Bleeding from a Dieulafoy lesion is an underdiagnosed source of upper gastrointestinal bleeding. The literature is almost universally in support of surgical therapy as its treatment. We report three patients with bleeding Dieulafoy lesions who were treated successfully with endoscopic therapy--two by bipolar electrocoagulation and one by endoscopic sclerotherapy.

Dieulafoy's disease of the large and small bowel.

The Dieulafoy lesion is a rare cause of severe gastrointestinal hemorrhage. The lesion is usually located in the stomach, although it may occur anywhere in the gastrointestinal tract. We describe four patients with extragastric Dieulafoy's disease, in the duodenum (one), the proximal jejunum (two), and the left hemicolon (one). Diagnosis was made by endoscopy in all four and confirmed by histology in three. The pathology of the Dieulafoy lesion is essentially the same throughout the gastrointestinal tract. Endoscopic treatment by sclerotherapy combined with electrocoagulation was successful in the duodenal and colonic Dieulafoy lesions, but not in the jejunal lesions.

Scoliosis induced by medullary damage: an experimental study in rabbits.

To date, there have been no reports of experiments designed to induce scoliosis by direct damage of different areas of the spinal cord. In a series of rabbits with medullary damage, the authors attempted selectively to interrupt the pathways that mediate proprioceptive input. Unilateral lesion of the dorsal column and posterior horn of the spinal cord was performed using three different techniques: coagulation with laser, stereotaxic microcoagulation, and longitudinal electrocoagulation. Of 32 operated rabbits, 17 developed scoliosis, exhibiting clear pathologic damage of the spinal cord. Electrophysiologic study, including EMG and analysis of the tonic -- vibratory reflex, was performed on 10 rabbits with medullary damage (scoliotic and non-scoliotic) and 12 matched controls. The data suggest disturbance of the sensory afferences that control the postural tone and consequent muscular imbalance, expressed as reduced activity in the muscles of the convex side. This work supports the view that loss of proprioceptive neural impulses caused by medullary damage can induce scoliosis.

Review of nonsurgical and surgical treatment and the role of insulin-sensitizing agents in the management of infertile women with polycystic ovary syndrome.

OBJECTIVES: To review the nonsurgical and surgical treatment and the role of insulin-sensitizing agents in the management of anovulatory infertile women with polycystic ovary syndrome (PCOS). MATERIALS AND METHODS: The search term of subfertile women with anovulation and PCOS was used for identification of randomized controlled trials. Nonrandomized controlled studies were identified through computer MEDLINE and EMBASE searches for the years 1980-2002. RESULTS: For obese PCOS women weight loss of > 5% of pretreatment weight restores menstrual regularity in 89%, of whom 30% achieved spontaneous pregnancy. It was estimated that 75-80% of anovulatory PCOS women will respond to clomiphene citrate (CC) and 35-50% will achieve pregnancy. For CC-resistant PCOS women (20-25%), CC + metformin (1.5 g/day) for 3-6 months has a 70% chance of restoration of regular menses and ovulation, and a 23% chance of pregnancy. Laparoscopic ovarian drilling (LOD) can be offered to CC-resistant PCOS women. There was no statistically significant difference in the ovulation rate following LOD with electrocoagulation and laser [83% vs. 77.5%; odds ratio (OR) 1.4; 95% CI 0.9-2.1], while there was a significantly higher cumulative pregnancy rate at 12 months after surgery (65% vs. 54.5%; OR 1.5; 95% CI 1.1-2.1). CONCLUSION: Diet and exercise followed by CC should be used for nonsurgical ovulation induction. For CC-resistant PCOS women, metformin may be included in a stepwise approach before a surgical approach. LOD with electrocautery is superior to laser drilling and gonadotropin therapy.

Two uterine arterial management methods in laparoscopic hysterectomy.

OBJECTIVE: The purpose of this study was to evaluate whether laparoscopic separation with coagulation of the uterine arteries and uterosacral ligaments can be used in an attempt to improve the operative procedure when hysterectomy is carried out by laparoscopic and vaginal method. METHOD: A prospective study was carried out in 70 women who underwent laparoscopic hysterectomy excluding total laparoscopic hysterectomy. Laparoscopic uterine arterial separation with coagulation (include laparoscopic reperitonization) was performed after laparoscopic detachment of the bladder and resection of the broad ligament (or adnexa) in 39 cases (Group 1). Uterine artery was coagulated by bipolar electrocoagulator and separated from the uterine side wall by scissors. Endoloop tie was applied to the arterial pedicle, if bleeding occurred. Uterine arterial management was performed through the vaginal route (include vaginal reperitonization) after laparoscopic procedure which was finished at the lower part of broad ligament with bladder detachment in 31 cases (Group 2). RESULTS: The average duration of operation was 84.0 min and 101.8 min in Groups 1 and 2, respectively (p < 0.05). The average amount of bleeding was 154.8 ml and 298.4 ml in Groups 1 and 2, respectively (p < 0.05). Hemoglobin decreased in average by 0.9 g/100 ml and 1.6 g/100 ml in Groups 1 and 2, respectively (p < 0.05). CONCLUSION: These results demonstrate that laparoscopic management of uterine arterial pedicles after bladder detachment could reduce the duration of operation time and amount of bleeding in laparoscopic hysterectomy.

Outpatient laparoscopic sterilisation: Comparison between electrocautery and clip application.

In a personal prospective series of 504 day-case laparoscopic sterilisations in 1977-78, unipolar tubal electrocoagulation was compared with spring-loaded clip application. Two patients who had cautery required laparotomy because of serious bleeding and one because of accidental bowel diathermy. Clip application was free from serious complications, but caused more post-operative pain. The majority of patients were performing normal or light household duties within 24 hours of sterilisation.

Electrosurgery: high-frequency modalities.

The most popular form of electrosurgery used in cutaneous surgery involves the application of high voltage electromagnetic energy in the form of a damped sine wave. This form of current may be applied by electrofulguration, electrodesiccation, or electrocoagulation. The principles involved in the application of these three forms of electrosurgery are discussed.

Frequency of use of suturing and repair techniques preferred by dermatologic surgeons.

BACKGROUND: There are many closure techniques and suture types available to cutaneous surgeons. Evidence-based data are not available regarding the frequency of use of these techniques by experienced practitioners. OBJECTIVE: To quantify, by anatomic site, the frequency of use of common closure techniques and suture types by cutaneous surgeons. METHOD: A prospective survey of the members of the Association of Academic Dermatologic Surgeons that used length-calibrated visual-analog scales to elicit the frequency of use of specific suture techniques. RESULTS: A response rate of 60% (61/101) indicated reliability of the received data. Epidermal layers were closed most often, in descending order, by simple interrupted sutures (38-50%), simple running sutures (37-42%), and vertical mattress sutures (3-8%), with subcuticular sutures used more often on the trunk and extremities (28%). The most commonly used superficial sutures were nylon (51%) and polypropylene (44%), and the most common absorbable suture was polyglactin 910 (73%). Bilayered closures, undermining, and electrocoagulation were used, on average, in 90% or more sutured repairs. The median diameters (defined as longest extent along any axis) of most final wound defects were 1.1 to 2.0 cm (56%) or 2.1 to 3.0 cm (37%). Fifty-four percent of wounds were repaired by primary closure, 20% with local flaps, and 10% with skin grafting, with the remaining 15% left to heal by second intent (10%) or referred for repair (5%). Experience-related differences were detected in defect size and closure technique: defects less than 2 cm in diameter were seen by less experienced surgeons, and defects greater than 2 cm by more experienced surgeons (Wilcoxon's rank-sum test: p=.02). But more experienced surgeons were less likely to use bilayered closures (r=-0.28, p=.036) and undermining (r=-0.28, p=.035). CONCLUSIONS: There is widespread consensus among cutaneous surgeons regarding optimal suture selection and closure technique by anatomic location. More experienced surgeons tend to repair larger defects but, possibly because of their increased confidence and skill, rely on less complicated repairs.

Catheter ablation for patients with cardiac arrhythmias.

Catheter ablative techniques have recently been introduced as therapy for patients with drug-resistant cardiac arrhythmias. These techniques include delivery of high-energy direct-current shocks in order to electrocoagulate the atrioventricular junction for those with supraventricular arrhythmias. This technique, if successful, results in arrhythmia control but induces chronic pacemaker dependency. The evidence, to date, suggests that 90% of these patients are improved after attempted atrioventricular junctional ablation. Catheter ablative procedures have been used for attempted ablation of accessory pathways and has been shown to be especially effective for those with posteroseptal accessory pathways. More recently, techniques for ablation of ventricular tachycardia foci have been introduced but experience with this procedure is too limited to allow for definitive recommendations.

Biomarker studies in reversed Barrett's esophagus.

OBJECTIVE: The purpose of this study was to use biomarkers to assess for cancer risk in Barrett's esophagus patients with either squamous islands or complete reversal of their intestinal metaplasia to squamous epithelium. METHODS: The biomarkers included proliferation characteristic using Ki-67, p53 abnormalities using immunohistochemical methods with two antibodies, DO-1 and DO-7, and ornithine decarboxylase (ODC) activity. RESULTS: Eleven patients had complete reversal produced by a combination of acid suppression and thermal injury (multipolar electrocoagulation). Ki-67 staining was indistinguishable from that of normal squamous esophageal epithelium, i.e., basal layer staining only. All 11 cases were negative for p53. ODC activity was low and in the range for normal squamous epithelium. Fourteen patients had squamous islands (partial reversal) after prolonged proton pump inhibitor therapy. Multilayer Ki-67 staining occurred in nine cases (64%), and six (43%) had areas of positive p53 staining. CONCLUSIONS: Initial biomarker studies suggest that completely reversed squamous epithelium is biologically similar to normal squamous epithelium and of low cancer risk. In contrast, partial reversal, manifest as squamous islands, is accompanied by biomarker abnormalities.

Impact of esophageal acid exposure on the endoscopic reversal of Barrett's esophagus.

OBJECTIVE: Normalization of esophageal acid exposure had been assumed to be necessary for the reversal of Barrett's esophagus with endoscopic therapy. This assumption is examined by evaluating the esophageal pH in a group of patients undergoing reversal therapy with fixed high-dose proton pump inhibitor therapy and endoscopic multipolar electrocoagulation (MPEC). METHODS: Patients with Barrett's esophagus of 2-6 cm in length were treated with omeprazole (40 mg b.i.d.). They underwent 24-h esophageal pH monitoring 5 cm above the upper margin of the lower esophageal sphincter determined by a water-perfused catheter. They then underwent MPEC therapy to an endpoint of elimination of Barrett's (reversal) by both endoscopy and biopsy 6 months after the last MPEC session or failure to achieve visual (endoscopic) reversal after six treatment sessions. RESULTS: Twenty patients had 24-h pH testing and reached a reversal endpoint. Three patients had abnormal pH tests, two total and supine and one supine only. These patients had documented reversal. The remaining 17 patients had normal pH testing but five failed reversal therapy. CONCLUSION: Barrett's esophagus can be completely reversed with endoscopic therapy despite abnormal esophageal acid exposure. Also, patients can fail reversal even with normal esophageal acid exposure. The necessary reduction of esophageal acid exposure for reversal therapy has yet to be defined.

Prospective trial of endoscopic clips versus combination therapy in upper GI bleeding (PROTECCT--UGI bleeding).

BACKGROUND: It is not known if combination therapy of epinephrine injection and multipolar electrocoagulation or hemoclips are a more efficient or effective treatment for patients with acute nonvariceal upper gastrointestinal (GI) bleeding. METHODS: Adult patients with active nonvariceal upper GI bleeding, a nonbleeding visible vessel, or after removal of an adherent clot findings of active bleeding or a visible vessel were studied. Patients were randomized to either therapy and the outcomes were assessed at 30 days. RESULTS: Forty-seven patients were studied: 26 patients randomized to hemoclips and 21 to combination therapy. There were 22 patients with active bleeding, 13 with a nonbleeding visible vessel, and 12 with an adherent clot. The median duration of endoscopic therapy was 17 min in the hemoclip group versus 20 min for the combination therapy, p= 0.29. Primary hemostasis with successful initial control of bleeding occurred in 26 (100%) of 26 hemoclip patients and 20 (95.2%) of 21 combination therapy patients, p= 0.45. The rebleeding rates were: 4 (15.4%) of 26 hemoclip patients versus 5 (23.8%) of 21 combination therapy patients, p= 0.49. Overall, the length of hospital stay, units of blood transfused, surgery rates, and mortality were not different. CONCLUSIONS: In this prospective, randomized controlled trial of endoscopic hemoclips versus combination therapy in the nonvariceal upper GI bleeding, the efficiency, efficacy, and complications of the two treatment modalities were not significantly different.
