Stapled hemorrhoidectomy--cost and effectiveness. Randomized, controlled trial including incontinence scoring, anorectal manometry, and endoanal ultrasound assessments at up to three months.

PURPOSE: Stapled hemorrhoidectomy is performed without leaving painful perianal wounds. The aim of this study was to assess any benefits, compared with a conventional open diathermy technique. METHODS: A total of 119 consecutive patients with prolapsed irreducible hemorrhoids were randomly assigned (conventional open diathermy technique = 62; stapled hemorrhoidectomy = 57). Preoperative fecal incontinence scoring, anorectal manometry, and endoanal ultrasound were performed. Postoperatively, these were repeated at up to three months with pain scores, analgesic requirements, quality of life assessment, and total related medical costs. RESULTS: Conventional open diathermy technique was quicker to perform (mean, 11.4 (standard error of the mean, 0.9) vs. 17.6 (3.1) minutes). Hospitalization was similar, but conventional open diathermy technique patients felt more pain during defecation (5.1 (0.4) vs. 2.6 (0.4); P < 0.005) at two weeks, and analgesic requirements were more for up to six weeks (P < 0.05). Up to the latter, 85.5 percent conventional open diathermy technique wounds remained unhealed, with more bleeding (33 (53.2 percent) vs. 19 (33.3 percent); P < 0.05) and pruritus (27 (43.5 percent) vs. 9 (15.8 percent); P < 0.05). Total complication rates were similar (conventional open diathermy technique 16 (25.8 percent) vs. stapled hemorrhoidectomy 10 (17.5 percent)), including mild strictures and bleeding in both groups. Minor incontinence occurred postoperatively in two conventional open diathermy technique and two stapled hemorrhoidectomy patients at six weeks. Endoanal ultrasound internal anal sphincter defects were found in the incontinent conventional open diathermy technique patients, but were asymptomatic in another one conventional open diathermy technique and one stapled hemorrhoidectomy. Only one patient (conventional open diathermy technique with internal sphincter defect) remained incontinent at three months. Changes between preoperative and postoperative anorectal manometry were similar in the two groups. Patients' satisfaction scores and quality of life assessments were also similar. Conventional open diathermy technique patients resumed work later (mean 22.9 (1.8) vs. 17.1 (1.9) days; P < 0.05), but the total costs incurred were less ($921.17 (16.85) vs. $1,283.09 (31.59); P < 0.005). CONCLUSIONS: Stapled hemorrhoidectomy is a safe and effective option in treating irreducible prolapsed piles. It is more expensive but less painful, with less time needed off work. Nonetheless, long-term results are still awaited.

Miscarriages among female physical therapists who report using radio- and microwave-frequency electromagnetic radiation.

Physical therapists are exposed to radio- and microwave-frequency electromagnetic radiation by operating shortwave and microwave diathermy units. Recent studies suggest that use of shortwave diathermy is associated with an excess risk of birth defects, perinatal deaths, and late spontaneous abortions among the offspring of exposed female therapists. To assess the impact of occupational use of microwave and shortwave diathermy at the time of conception, the authors mailed questionnaires to 42,403 physical therapists in 1989. Both occupational and reproductive histories were obtained. Exposures to shortwave and microwave diathermy were both assessed in the same fashion and were examined in relation to early recognized fetal loss in a nested case-control design. A total of 1,753 case pregnancies (miscarriages) were matched to 1,753 incidence density control pregnancies (other pregnancies except ectopic pregnancies). A pregnancy was considered "exposed" if the mother reported using microwave or shortwave diathermy anytime during the 6 months prior to the first trimester or during the first trimester. Pregnancies of mothers reporting microwave use 6 months prior to the pregnancy or during the first trimester were more likely to result in miscarriage (odds ratio (OR) = 1.28, 95% confidence interval (CI) 1.02-1.59). The odds ratio increased with increasing level of exposure (chi 2 = 7.25, p < 0.005). The odds ratio in the highest exposure group (20 or more exposures/month) was 1.59. The overall odds ratio was slightly lower after it was controlled for prior fetal loss (OR = 1.26, 95% CI 1.00-1.59), but the exposure-response effect remained (chi 2 = 5.17, p < 0.01). The risk of miscarriage was not associated with reported use of shortwave diathermy equipment (OR = 1.07, 95% CI 0.91-1.24). The odds ratio in the highest exposure group was 0.87.

Inferior turbinate reduction in children using Holmium YAG laser-a clinical and histological study.

BACKGROUND AND OBJECTIVES: To compare the efficacy and safety of inferior turbinate reduction in children using Holmium:YAG (Ho:Yag) laser and diathermy. Histological effects of these treatments on turbinate tissue are also studied. STUDY DESIGN/MATERIALS AND METHODS: A retrospective review and structured telephone interview of paediatric cases treated with Ho:Yag laser and diathermy to inferior turbinates. The complications, morbidity and efficacy were quantified. Histological sections of inferior turbinates treated with diathermy (surface and submucosal) and laser were compared. RESULTS: Efficacy in the laser (n = 8) and diathermy group (n = 11) was similar. The complication/morbidity score was lower in the laser group, 1.92 versus 3.48, (P = 0.04, CI: 0.01, 2). Long-term benefit was 50 and 36% in the laser and diathermy group respectively. Histology showed very limited tissue damage in all methods of treatment. CONCLUSIONS: Ho:Yag laser treatment is equally efficacious, but causes less complications and morbidity compared to surface diathermy. Both treatment methods have poor long-term efficacy, which may be related to limited tissue damage.

Surgical management of intractable epistaxis: audit of results.

We have audited our results after changing the management practice in patients with intractable epistaxis. These patients are offered trans-nasal endoscopic sphenopalatine artery diathermy with or without anterior ethmoid artery diathermy instead of conventional surgical procedures. During the first year after the change in practice, 145 patients were treated as inpatients for epistaxis. Ten patients (seven per cent) required a surgical procedure under general anaesthesia due to the recurrent nature of bleeding. All 10 patients had endoscopic sphenopalatine artery diathermy, whereas in four patients anterior ethmoid artery diathermy was also performed concurrently. The post-operative hospital stay ranged from one to three days (mean 2.1 days). The mean follow-up was 10 months. The epistaxis recurred in one patient and this was managed conservatively. There were no complications related to surgery. In the previous year, 132 patients were admitted for epistaxis and eight patients had surgical procedures, which included septoplasty, nasal packing and external carotid artery ligation. The post-operative stay ranged from three to six days (mean 3.9 days). Our audit shows that endoscopic sphenopalatine artery diathermy is a safe, successful and effective management option for patients with refractory epistaxis. The morbidity is reduced and the hospital stay is shortened. The sphenopalatine artery diathermy can be combined with anterior ethmoid surgery, when necessary.

A prospective randomised single blinded study comparing harmonic scalpel tonsillectomy with bipolar tonsillectomy.

OBJECTIVE: To compare the differences in pain, analgesic use and bleeding in children after tonsillectomy using either a harmonic scalpel or a bipolar diathermy surgical technique. METHODS: Children 6-15 years presenting for tonsillectomy were randomised to either a harmonic scalpel or bipolar diathermy surgical technique. Post-operative pain scores (VAS, 0-10) were recorded within 30 min of surgery and again at the 4h hospital discharge. A subsequent telephone interview daily for 7 days and then every second day until day 13 was used to monitor pain scores, analgesic use and tonsil bed bleeding. RESULTS: There were 204 children studied. The response rate over the first 7 days was 93% for the children in the harmonic scalpel group and 87% for the bipolar group. Children experienced moderate post-operative pain for the first 6 days, after which pain declined from 4-7 to reach a score of 1-2 by day 11. Children undergoing harmonic scalpel tonsillectomy (n=103) reported higher mean pain scores than those who underwent bipolar diathermy (n=101) for current pain (4.7 versus 4.2, p=0.002), worst pain of the day (6.9 versus 6.2, p<0.001) and pain on swallowing (5.9 versus 5.2, p<0.001) over the first 6 post-operative days. Analgesic use (acetaminophen, ibuprofen) was similar in both groups. Hospital readmission for bleeding in children who underwent harmonic scalpel was similar to those who underwent bipolar diathermy tonsillectomy (9% versus 11%) as was bleeding requiring surgical re-exploration (4% versus 2%). CONCLUSIONS: Tonsillectomy was associated with considerable pain for the first 6 post-operative days. Children undergoing harmonic scalpel tonsillectomy had a slight increase in pain compared to the bipolar diathermy group during this time. Both methods of tonsillectomy are effective and safe.

Tonsillectomy technique as a risk factor for postoperative haemorrhage.

BACKGROUND: Tonsillectomy is one of the most frequent surgical procedures. "Hot" tonsillectomy techniques (eg, diathermy and coblation) have become well established, but there is little evidence to suggest that they are better than traditional "cold steel" dissection with only packs or ties for haemostasis. METHODS: We obtained data for the occurrence of complications after all tonsillectomies done since July, 2003, in England and Northern Ireland. We recorded postoperative haemorrhages and other complications, taking place within 28 days of surgery, that led to delayed discharge, return to theatre, or re-admission. By February, 2004, the audit had included 13554 patients, of whom 11796 (87%) in 252 hospitals consented to electronic submission of their tonsillectomy data. Thus, 75% of the hospitals where tonsillectomies are done submitted data for 60% of all eligible patients. FINDINGS: Haemorrhage occurred in 389 patients (3.3%). 59 patients (0.5%) had a primary haemorrhage (during initial stay), 337 (2.9%) a secondary haemorrhage (after discharge), and seven had both. The overall haemorrhage rate was 3.1 times (95% CI 1.9-5.0) higher with bipolar diathermy tonsillectomy than with cold steel tonsillectomy without any use of diathermy (p<0.001). The corresponding relative risk for coblation tonsillectomy was 3.4 (1.9-6.2; p<0.001). When cold steel was used for dissection and diathermy only for haemostasis the relative risk was 2.2 (1.3-3.7; p=0.002). INTERPRETATION: The use of techniques such as diathermy and coblation increased postoperative haemorrhage. These methods should therefore be used with appropriate caution and only after proper training.

The effects of physiotherapy on osteoarthritic knees of females.

The purpose of this study was to investigate the effect of ultrasound and shortwave diathermy, with and without therapeutic exercise on osteoarthritic (OA) knees. From February 1987 to January 1989, we collected 94 OA knees from 61 female patients and divided them into 4 groups. Group 1 received ultrasound therapy, group 2 had shortwave diathermy, group 3 received ultrasound and an exercise program, and group 4 received shortwave diathermy and exercise therapy. All 61 patients (94 knees) were assessed by functional incapacity scoring and isokinetic testing before and after treatment. At the termination of treatment, all patients had significant improvement in both functional capacity and peak torque. This study failed to prove any significant difference in treatment effect between ultrasound and shortwave diathermy for chronic OA knees. However, the exercise program in addition to the diathermy did promote the treatment effect in both function and muscle torque.

Cause and prevention of electrosurgical injuries in laparoscopy.

BACKGROUND: Electrosurgical injuries occur during laparoscopic operations and are potentially serious. The overall incidence of recognized injuries is between one and two patients per 1,000 operations. The majority go unrecognized at the time of the electrical insult and commonly present three to seven days afterward with fever and pain in the abdomen. Since these injuries appear late the pathophysiology remains speculative. STUDY DESIGN: This article reviewed the physics of electrosurgery and provides the surgeon with an insight to the mechanisms responsible in each type of injury. In addition, a comprehensive search of the world literature has reviewed all articles on the topic. RESULTS: The main causes of electrosurgical injuries are: inadvertent touching or grasping of tissue during current application, direct coupling between a portion of intestine and a metal probe that is touching the activated probe, insulation breaks in the electrodes, direct sparking to the intestine from the diathermy probe, and current passage to the intestine from recently coagulated, electrically isolated tissue. The majority of injuries, not surprisingly, are caused by monopolar diathermy. Bipolar diathermy is safer and should be used in preference to monopolar diathermy, especially in anatomically crowded areas. CONCLUSIONS: An awareness of the hazards of diathermy together with an understanding of the mechanisms of injury should enable the surgeon to dissect tissue and to achieve hemostasis, while at the same time decreasing the risk of serious complications to the patient.

[The surgical treatment of hemorrhoids: diathermocoagulation and traditional technics. A prospective randomized study].

INTRODUCTION: The operations to treat hemorrhoids of III and IV degree are numerous but classifiable into two groups: "closed" techniques such as Ferguson, Parks and Khubchandani, and "open" techniques such as Arnous-Parnaud of the most famous Milligan-Morgan. Recently the Anglo-Saxon school was proposed a technical variant to Milligan-Morgan operation: it involves diathermy excision without peduncle ligature. This technique partly because of the coagulation of the pain receptor, partly because of the absence of "at risk" sutures in septic ground would involve a reduction in the postoperative pain. We have developed the following study to have a global valuation of these methodologies. MATERIALS AND METHODS: From November 1993, 135 patients with haemorrhoids of III and IV degree have been recruited and grouped in 3 random groups: the patients of the I group have been subjected to closed hemorrhoidectomy (Ferguson and is variant according to Khubchandani), the patients of the II group have been subjected to the Milligan-Morgan operation and those the III group of the diathermy hemorrhoidectomy. All the patients have had the same kind of preoperative preparation and the same kind of analgesic during the post-operative course. Before the operation all the patients were given a questionnaire including a scale of the pain on which the administrations of analgesic were also noted. RESULTS: A faster canalization and a minor postoperative pain were found in the patients of the II and III group and among them a minor use of analgesics in those subjected to diathermy-hemorrhoidectomy. No statistical difference occurred in postoperative haemorrhage into Milligan-Morgan and diathermy hemorrhoidectomy without peduncle ligature (2.2%). CONCLUSIONS: All the methods we have considered have turned out to be effective for the clinical and anatomical recovery. However, in our experience, the open techniques involve in a significant reduction of the postoperative pain and those made with diathermy permit a minor use of analgesics in comparison with those made a conventional scissor excision. Finally the peduncle ligature doesn't influence postoperative haemorrhage.

Partial distal pancreatectomy with a hand-held CO2 laser. An experimental study.

Partial distal pancreatectomy was performed in dogs with CO2 laser. Results were compared with those obtained with use of diathermy and scalpel. Postoperative hyperamylasemia appeared in all the animals. The highest peaks in the laser and scalpel groups were found on the fifth postoperative day, after which they gradually returned to normal; the highest levels appeared in the diathermy group on the 21st day, and returned to normal only after 56 days. Pancreatography showed a sealed duct in the laser and diathermy groups although no duct ligation was performed. Histological study of the laser group disclosed initial thermal injury at the cut section with no damage to the nearby parenchyma, followed later by a smooth, thin scar. In the diathermy and scalpel groups, the injured zone became enlarged later by active parenchymal and interlobular inflammation in the underlying tissue.

The effect of local heat and cold therapy on the intraarticular and skin surface temperature of the knee.

OBJECTIVE: To evaluate the effects of local application of ice chips, ligno-paraffin, short-wave diathermy, and nitrogen-cold air on skin and intraarticular temperature. METHODS: Forty-two healthy subjects were divided into 4 treatment groups. A temperature probe was inserted into the knee joint cavity and another placed on the overlying skin, and changes in temperature over 3 hours, by treatment group, were recorded. RESULTS: The mean skin surface temperature dropped from 27.9 degrees C to 11.5 degrees C after application of ice chips, and from 28.8 degrees C to 13.8 degrees C after application of cold air. The mean intraarticular temperature decreased from 31.9 degrees C to 22.5 degrees C and from 32.9 degrees C to 28.8 degrees C, respectively, after these 2 treatments. Shortwave diathermy increased skin temperature by 2.4 degrees C; intraarticular temperature was increased only 1.4 degrees C by short-wave diathermy. Treatment with ligno-paraffin increased the skin surface temperature 8.9 degrees C; the temperature in the joint cavity was increased 3.5 degrees C. CONCLUSION: The use of short-wave diathermy and superficial heat packs in the treatment of patients with arthritis may potentially cause harm by increasing intraarticular temperature. This may have major implications regarding treatment policy for patients with arthritis.

An experimental evaluation of ablation devices for the local treatment of the liver resection edge.

UNLABELLED: Surgical margin is the only technical variable that has an impact on long-term outcome after liver resection. In this study we compared radiofrequency (RFA), cryotherapy, diathermy and argon beam for the local treatment of liver resection edge. METHODS: Sixty eight ablations were produced on the surface of ex vivo sheep liver using the various modalities. Cryoablations were produced using both the Cryotech and the Erbe probes. Radiofrequency ablations were produced using a custom-made surface application probe and the RITA 1500 generator. Conmed 7500 system was used to produce diathermy and argon beam coagulation. RESULTS: Argon beam and the diathermy resulted in ablation to maximum depth of 3.5 mm with endpoint and spray modes at various power setting. RF ablation resulted in consistent ablations the diameter of which varied in a linear manner to the time of RF application and the depth of the ablations with the length of electrode deployment. Cryotherapy was as effective as RFA with both the cryotherapy systems but the Erbe trocar probe resulted in a deeper ablation, whereas the Cryotech paddle probe resulted in a larger diameter ablation. CONCLUSIONS: RF and cryotherapy are equally effective as liver edge ablation device. Diathermy and argon are considered less effective. Cryotherapy requires expensive complex equipment that at least with liquid nitrogen systems requires to be prepared for use and this may not be available if the need for edge treatment during resection was unplanned.

The impact of treatment on the natural history of endometriosis.

A group of 50 infertile female patients was assessed laparoscopically to study the natural history of endometriosis. They were treated either with danazol (n = 21), or diathermy ablation (n = 13) or had conservative surgery with postoperative danazol (n = 5) or were left untreated (n = 11). All these patients had second look laparoscopy performed after a mean interval of 12 months (range 9-18 months). Improvement was noted among 53% of those treated with danazol, 70% treated with diathermy, 80% treated with surgery and danazol and 27% of those left untreated. The status of endometriosis remained unchanged among 14% of those treated with danazol, 8% treated by diathermy and 9% of those left untreated. However, the disease became worse in the remaining women, 33% in the danazol treated group, 22% treated by diathermy, 20% treated with surgery and danazol and 64% of those left untreated. Thus treatment hinders progression in a majority of patients, and conversely, there is a small but definite spontaneous regression rate.

Technical basis for the application of localized hyperthermia.

Techniques of localized hyperthermia have been developed these last years. Very superficial tumors may be heated by infra-red radiation, radiative diathermy at high frequencies (2450 MHz) or even by techniques of contact hyperthermia. Superficial tumors (some cm deep) may be heated by radiative diathermy at lower frequencies (434 MHz or 915 MHz), inductive diathermy or ultrasound. Deeper tumors (about 10 cm deep) are the most problematic. They may be heated by capacitive diathermy at frequencies of 13.5 or 27 MHz under favourable conditions, or perhaps by ultrasound when multiple transducers are used. Hyperthermic extracorporeal perfusion (in limbs) and interstitial hyperthermia are efficient and promising techniques but their indications are limited.

Thermal tissue damage following laser and large loop conization of the cervix.

OBJECTIVE: To compare thermal injury zones produced with laser and diathermy loop conization. METHODS: Excisional cervical specimens (cones and cervices) were obtained from 40 consecutive women who underwent abdominal hysterectomy. The subjects were assigned to have either laser or diathermy loop conization (20 in each group). The duration of each procedure was recorded. Histopathologic measurements of thermal injury zones were performed in all specimens. RESULTS: The techniques produced cone specimens of similar depth. The mean depth of thermal injury produced with laser conization in cone specimens (mean +/- standard deviation 0.49 +/- 0.16 mm) and cervical craters (0.58 +/- 0.24 mm) was significantly greater (P < .001) than the corresponding depth in cone specimens (0.22 +/- 0.09 mm) and cervical craters (0.27 +/- 0.11 mm) obtained by diathermy loop excision. The mean time of the two procedures was also significantly different (P < .001); laser conization 11 +/- 4.5 minutes and loop conization 2 +/- 1.2 minutes. CONCLUSION: For routine conization, loop diathermy causes less thermal damage to the specimen and is a faster procedure than laser.

Which is more painful? A randomized trial comparing loop with laser excision of the cervical transformation zone.

We compared the pain of excisional cervical surgery by the laser or loop diathermy (LLETZ) in a randomised controlled clinical trial. Eighty women with CIN III were recruited from a laser colposcopy clinic specifically adapted to run randomized trials. They were scheduled for excision of their cervical transformation zone and both groups were matched for age, parity, and size of lesion. We measured linear analogue pain scores, subjective pain scores, and operative time. The laser and loop diathermy inflicts similar discomfort and there is no detectable difference between the median pain scores of women in either group (P = 0.99). However, in the hands of an experienced surgeon it takes 4 min extra to excise the cervical transformation zone with a laser compared to loop diathermy. The average time from sitting in the chair to the end of the procedure was 13.02 min (SD 3.65) for the group allocated diathermy surgery compared to 17.30 min (SD 5.33) for a laser excision log transformed t(log transformed data) = 3.7 (P < 0.001).

Post-tonsillectomy hemorrhage: cold versus hot dissection.

OBJECTIVE: The aim of our study was to assess the rate of reactionary and secondary posttonsillectomy hemorrhage using "cold" dissection and bipolar diathermy and to determine whether there was any difference in the postoperative hemorrhage rate between the 2 methods. METHODS: This was a prospective study of all patients undergoing tonsillectomy between November 8, 1999 and November 7, 2000 in a tertiary medical centre. The data collected included patient identity, age, gender, date of surgery, method of operation, and complications (if any). The timing of reactionary or secondary posttonsillectomy hemorrhage and the treatment were recorded. We hypothesized no difference in posttonsillectomy hemorrhage rates using the 2 methods. Chi2 test was used for statistical analysis. RESULTS: A total of 349 patients underwent tonsillectomy in the period (134 males, 215 females, mean age was 16.7 years). Of these, 337 were bilateral procedures, 145 patients had tonsillectomy using cold dissection, and 192 patients had bipolar diathermy. Reactionary hemorrhage occurred in 1 patient (0.3%) and 31 patients (9.2%) developed secondary hemorrhage. The hemorrhage rates using cold dissection (n = 8) and bipolar diathermy (n = 24) were 5.5% and 12.5%, respectively ( P < 0.05). CONCLUSIONS: The primary and secondary posttonsillectomy hemorrhage rates were 0.3 and 9.2%, respectively. Tonsillectomy using bipolar diathermy has a statistically significant higher secondary hemorrhage rate than using cold dissection (12.5% vs. 5.5%, P < 0.05).

Paediatric tonsillectomy: bipolar electrodissection and dissection/snare compared.

Tonsillectomy is a common operation in children performed by a variety of techniques. Recently we have introduced a modified form of electrodissection tonsillectomy using bipolar diathermy. A prospective study was designed to evaluate this technique against the conventional dissection/snare technique. Sixty children were entered into each section of the study (total 120 children). There is a statistically significant shorter operating time (mean 11.2 minutes) and lower intraoperative blood loss (mean 5 ml) using the bipolar diathermy technique. Post-operatively, the children who had bipolar diathermy tonsillectomy were found to be able to drink and eat significantly earlier than the cold dissection group. There was no measurable difference in analgesia requirements before discharge and the time of discharge between the two methods. Post-operative haemorrhage occurred in two out of 60 (3.4 per cent) and one out of 60 (1.7 per cent children) in the conventional and bipolar diathermy dissection, respectively, but this was not statistically significant.
