Comparison of three common tonsil surgery techniques: cold steel with hot hemostasis, monopolar and bipolar diathermy.

PURPOSE: To analyze the risk of postoperative hemorrhage in tonsil surgery with different surgical methods, instruments, indications, and age groups. Monopolar diathermy compared to bipolar diathermy was of particular interest. METHODS: The data from tonsil surgery patients were retrospectively collected between 2012 and 2018 in the Hospital District of Southwest Finland. The surgical method, instruments, indication, sex and age and their association with a postoperative hemorrhage were analyzed. RESULTS: A total of 4434 patients were included. The postoperative hemorrhage rate for tonsillectomy was 6.3% and for tonsillotomy 2.2%. The most frequently used surgical instruments were monopolar diathermy (58.4%) cold steel with hot hemostasis (25.1%) and bipolar diathermy (6.4%) with the overall postoperative hemorrhage rates 6.1%, 5.9% and 8.1%, respectively. In tonsillectomy patients, the risk for a secondary hemorrhage was higher with bipolar diathermy compared to both monopolar diathermy (p = 0.039) and the cold steel with hot hemostasis technique (p = 0.029). However, between the monopolar and the cold steel with hot hemostasis groups, the difference was statistically non-significant (p = 0.646). Patients aged > 15 years had 2.6 times higher risk for postoperative hemorrhage. The risk of a secondary hemorrhage increased with tonsillitis as the indication, primary hemorrhage, tonsillectomy or tonsillotomy without adenoidectomy, and male sex in patients aged ≤ 15 years. CONCLUSION: Bipolar diathermy increased the risk for secondary bleedings compared to both monopolar diathermy and the cold steel with hot hemostasis technique in tonsillectomy patients. Monopolar diathermy did not significantly differ from the cold steel with hot hemostasis group regarding the bleeding rates.

Scalpel versus diathermy skin incision in Caesarean section.

Surgical scalpels are traditionally used for skin incisions during a Caesarean delivery; the great evolutions in electrosurgical devices bring an alternative method for skin incision by the usage of cutting diathermy. This was a prospective randomised comparative study conducted during the period from March 2016 to February 2017 on 200 patients, 100 patients had skin incisions using the surgical scalpel, while 100 patients had skin incisions with a diathermy, in order to judge the variations in the postoperative pain, the incision time, the incision blood loss, the operative time, the wound healing and the wound complications. We observed a significant difference between the two groups regarding the incision time (p < .001), incisional blood loss (p < .001), operative time (p < .001) and the postoperative pain (p < .001), where these parameters were less in the diathermy group. No significant difference observed between the two groups regarding the wound healing (p = .389) and wound complications (p = .470). We can conclude that the proper usage of diathermy in making the skin incision during a Caesarean section in this study achieved better results than the scalpel incision. Impact statement What is already known on this subject? Surgical scalpels are traditionally used in making the skin incisions during a Caesarean section; diathermy incisions, on the contrary, are less popular among the surgeons. It has been hypothesised that the application of extreme heat may result in a significant postoperative pain and poor wound healing. There has been a widespread use of diathermy for hemostasis but fear of production of large scars and improper tissue healing has restricted their usage in making skin incisions. What do the results of this study add? The use of diathermy for skin incisions in Caesarean section in this study was associated with a reduced incisional blood loss, incisional time, operative time and postoperative pain. It had no effect on wound closure and was not associated with any delay in wound healing. Also, the wound complications rate was equal in both types of incisions. What are the implications of these findings for clinical practice and/or further research? Most surgeons prefer the scalpel in making skin incision during a Caesarean section due to the fear of surgical site infection. Our findings proved different, we proved that cutting diathermy could be accepted as an alternative technique for making a skin incision without increased rates of wound infections. Also, the advantages of cutting diathermy will give benefits to both the patients and the surgeons.

Blood Perfusion in Human Eyelid Skin Flaps Examined by Laser Speckle Contrast Imaging-Importance of Flap Length and the Use of Diathermy.

PURPOSE: It is well known that blood perfusion is important for the survival of skin flaps. As no study has been conducted to investigate how the blood perfusion in human eyelid skin flaps is affected by the flap length and diathermy, the present study was carried out to investigate these in patients. METHODS: Fifteen upper eyelids were dissected as part of a blepharoplastic procedure, releasing a 30-mm long piece of skin, while allowing the 5 mm wide distal part of the skin to remain attached, to mimic a skin flap (hereafter called a "skin flap"). Blood perfusion was measured before and after repeated diathermy, using laser speckle contrast imaging. RESULTS: Blood perfusion decreased from the base to the tip of the flap: 5 mm from the base, the perfusion was 69%, at 10 mm it was 40%, at 15 mm it was 20%, and at 20 mm it was only 13% of baseline values. Diathermy further decreased blood perfusion (measured 15 mm from the base) to 13% after applying diathermy for the first time, to 6% after the second and to 4% after the third applications of diathermy. CONCLUSIONS: Blood perfusion falls rapidly with distance from the base of skin flaps on the human eyelid, and diathermy reduces blood perfusion even further. Clinically, it may be advised that flaps with a width of 5 mm be no longer than 15 mm (i.e., a width:length ratio of 1:3), and that the use of diathermy should be carefully considered.

Post-tonsillectomy pain after using bipolar diathermy scissors or the harmonic scalpel: a randomised blinded study.

OBJECTIVE: To compare the postoperative pain following bipolar diathermy scissors tonsillectomy (higher temperature dissection) with harmonic scalpel tonsillectomy (lower temperature dissection). METHODS: Sixty patients aged 7-40 years planned for tonsillectomy with no other concurrent surgery were randomised to either bipolar diathermy scissors or harmonic scalpel as surgical technique. Blinded to the surgical technique, the patients recorded their pain scores (VAS, 0-10) at awakening and the worst pain level of the day in the postoperative period. All intake of pain medication was also recorded. RESULTS: No statistically significant differences were found between the two groups regarding postoperative pain levels or consumption of pain medication. CONCLUSION: Usage of the harmonic scalpel does not render less postoperative pain following tonsillectomy when compared with usage of the bipolar diathermy scissors.

Microwave Treatment for Axillary Hyperhidrosis and Bromhidrosis. / Tratamiento con microondas en la hiperhidrosis y bromhidrosis axilar.

Axillary hyperhidrosis (AH) and bromhidrosis are common causes of consultation in dermatology. Currently, the most widely prescribed treatment for AH is botulinum toxin, a very effective but temporary option; it is totally ineffective in bromhidrosis. Sympathectomy is an increasingly infrequent choice of treatment due to the high incidence of compensatory hyperhidrosis. We describe the treatment of AH and bromhidrosis with a novel microwave device that can fibrose eccrine and apocrine glands, achieving possibly permanent results. The procedure should preferably be performed under tumescent anesthesia. Side effects, principally local inflammation, are transient. Clinical effectiveness and safety, supported by recently published studies, position this technique as a first-choice option both for hyperhidrosis and for bromhidrosis.

Subdermal Radiofrequency for Skin Tightening of the Posterior Upper Arms.

BACKGROUND: Subsurface thermistor-controlled monopolar radiofrequency (SMRF) is an emerging technology designed to offer a minimally invasive option for tightening of lax skin. The versatility of this technique allows it to be applied to virtually any body site. OBJECTIVE: The purpose of this study is to evaluate the safety and efficacy of SMRF for tightening of posterior upper arm skin laxity. PATIENTS: This is a prospective, open-label clinical trial involving 12 subjects aged 18 to 65 with moderate-to-severe skin laxity in the posterior upper arms. METHODS/MATERIALS: Each subject received treatment to the bilateral arms resulting in a population of n = 24 arms in the analysis group. Treatment consisted of SMRF delivered at Day 0 of the trial. Follow-up evaluation was conducted at Day 7, 30, and 90 post-treatment. The primary end point was the assessment of skin laxity by a nontreating physician utilizing a standardized 5 point Skin Laxity Grading Scale at baseline, Days 30 and 90. Subject self-evaluation of firmness, laxity, texture, and satisfaction was also collected. Circumferential and vertical arm measurements were obtained via digital fractional caliper. An adverse event profile was categorized. RESULTS: Significant improvements in skin laxity were observed at both Day 30 and at Day 90 post-treatment as assessed by the nontreating investigator. Subjects also rated significant improvements in the firmness, texture, and laxity of their treated arms. The majority of subjects were "satisfied" to "extremely satisfied" with their results. Adverse events recorded at Day 7 post-treatment included erythema (4%), contour irregularity (4%), and bruising (13%). All adverse events resolved completely by Day 30 post-treatment. CONCLUSION: Thermistor-controlled SMRF is a safe and effective means to treating posterior upper arm skin laxity.

Hyperthermic intraperitoneal chemotherapy plus high-frequency diathermic therapy followed by intravenous chemotherapy versus intravenous chemotherapy alone for postoperative adjuvant treatment of gastrointestinal cancer: a comparative research study.

PURPOSE: To evaluate the therapeutic efficacy and toxicity of hyperthermic intraperitoneal chemotherapy (HIPEC) plus high-frequency diathermic therapy (HFDT) followed by intravenous chemotherapy vs intravenous chemotherapy alone for adjuvant treatment of postoperative gastrointestinal neoplasms. METHODS: Fifty-two gastrointestinal carcinoma patients who were radically operated were enrolled and divided into the treatment group and the control group. In the treatment group, 25 patients were treated with combination of HIPEC+HFDT and subsequent intravenous chemotherapy, while in the control group 27 patients received intravenous chemotherapy alone. Post-therapeutic complications and adverse reactions, time to progression (TTP) and overall survival (OS) were compared between these two groups. RESULTS: Difference in toxic reactions between the two groups was not statistically significant (p>0.05). Postoperative progression- free survival (PFS) rate at 12 and 40 months after radical surgery was 72.0 and 54.0% respectively in the treatment group, and 65.8 and 11.5% respectively in the control group (p=0.108). TTP was statistically significantly longer in the treatment group than in the control group (median TTP 40.1 vs 18.5 months, p=0.027). Postoperative OS at 12 and 20 months after radical surgery was 88.0 and 78.0% respectively in the treatment group and 92.6 and 72.7% in the control group, without significant difference. CONCLUSION: After radical surgery, combination of HIPEC+HFDT and subsequent intravenous chemotherapy brings about superior PFS compared with intravenous adjuvant chemotherapy alone, while having no more complications and adverse reactions.

Randomized double-blind trial comparing the cosmetic outcome of cutting diathermy versus scalpel for skin incisions.

BACKGROUND: Controversy exists about whether cutting diathermy for skin incisions leads to a cosmetically inferior scar. Cosmetic outcomes were compared between skin incisions created with cutting diathermy versus scalpel. Wound infection rates and postoperative incisional pain were also compared. METHODS: This was a randomized double-blind trial comparing cutting diathermy and scalpel in patients undergoing bowel resection. Scar cosmesis was assessed at 6 months after surgery by a plastic surgeon and a research associate using the Vancouver Scar Scale (VSS) and the Patient and Observer Scar Assessment Scale (POSAS). Patients also used POSAS to self-evaluate their scars. Wound infections within 30 days were recorded, and incision pain scores were measured on the first 5 days after operation. RESULTS: A total of 66 patients were randomized to cutting diathermy (31) or scalpel (35). At 6 months, there was no significant difference between the diathermy and scalpel groups in mean(s.d.) VSS scores (4·9(2·6) versus 5·0(1·9); P = 0·837), mean POSAS total scores (19·2(8·0) versus 20·0(7·4); P = 0·684) or subjective POSAS total scores (20·2(12·1) versus 21·3(10·4); P = 0·725). Neither were there significant differences in wound infection rates between the groups (5 of 30 versus 5 of 32; P = 1·000). Pain scores on day 1 after operation were significantly lower in the diathermy group (mean 1·68 versus 3·13; P = 0·018), but were not significantly different on days 2-5. CONCLUSION: Cutting diathermy is a cosmetically acceptable technique for abdominal skin incisions. There is no increased risk of wound infection, and diathermy may convey benefit in terms of early postoperative wound pain. REGISTRATION NUMBER: NCT01496404 ( http://www.clinicaltrials.gov).

[Penile necrosis resulting from post-circumcision microwave diathermy: A report of 9 cases].

OBJECTIVE: To investigate the pathogenesis and treatment of penile necrosis resulting from microwave diathermy following circumcision. METHODS: We retrospectively analyzed the clinical data about 9 cases of penile necrosis resulting from postoperative microwave diathermy following circumcision. The 9 males, aged 20 - 39 (mean 26) years, underwent traditional circumcision for redundant prepuce or phimosis in other hospitals, followed by microwave diathermy for 30 - 60 minutes daily, which resulted in penile necrosis. With no response to conservative therapy, the patients were referred to our hospital at 3 -30 days postoperatively. Of the 9 patients, 5 presented with dry gangrene and 4 with moist gangrene. Six of the patients underwent partial penectomy, including 1 that received penis lengthening.3 months later, while the other 3 underwent total penectomy for total penile necrosis followed by penile reconstruction 3 months later, with deep inferior epigastric perforator (DIEP) flaps and by implantation of the 12th costal cartilage in 2 cases and with epigastric groin island flaps and by urethroplasty in the other. RESULTS: The patients were followed up for 2 - 8 years, and all could urinate smoothly in the standing position. Of the 6 men treated by partial penectomy, 1 received penis lengthening and achieved a penile length of 7 cm and 5 had the remaining penile length of 3 -5 cm, 4 with erectile function and the other 2 capable of sexual intercourse. The 3 men treated by total penectomy achieved nearly normal external appearance of the penis, with a finalized length of (11.7 ± 1.3) cm, a circumference of (11.4 ± 2.1) cm, and a normal feel of the skin. Of the 3 cases of penile reconstruction, 2 achieved sufficient erectile hardness of the penis (grade 3) for sexual intercourse, while the other 1 remained impotent. CONCLUSION: Post-circumcision microwave diathermy may result in penile necrosis, for the management of which, early debridement is necessitated and penile lengthening or reconstruction can be performed according to the severity of the lesion and needs of the patient.

Nursing and safety of silver needle diathermy treating ankylosing spondylitis.

This paper aims to discuss the nursing and safety of silver needle diathermy in the treatment for ankylosing spondylitis. We nursed 46 patients with ankylosing spondylitis treated with silver needle diathermy. Specific nursing was focused on physical condition evaluation and mental nursing before treatment, observation during and after treatment, diet nursing, needle eye nursing, functional training and propaganda and education when discharged. The result suggested that all the patients received mental nursing, diet guide, skin care, health education, functional training and follow-up visit from the nurse and all of them could endure silver needle diathermy as discomfort or drug allergy was barely found, so were slight scald and skin infection nearby the needle eye caused by fainting during acupuncture, accidental puncture or overheat. Follow-up visit showed that no patient suffered obvious untoward effect and the pain, joint range of motion and living condition were distinctly improved a week after discharging. In conclusion, during the treatment for ankylosing spondylitis applying silver needle diathermy, the nursing before, during and after the treatment can obviously reduce the complication, accelerate the recovery, which is highly safe.

Real time shear waves elastography monitoring of thermal ablation: in vivo evaluation in pig livers.

BACKGROUND: Thermal ablation is a widely used minimally invasive treatment modality for different cancers. However, lack of a real-time imaging system for accurate evaluation of the procedure is one of the reasons of local recurrences. Shear waves elastography (SWE) is a new ultrasound (US) imaging modality to quantify tissue stiffness. The aim of the study was to assess the feasibility and accuracy of US elastography for quantitative monitoring of thermal ablation and to determine the elasticity threshold predictive of coagulation necrosis. METHODS: A total of 29 in vivo thermal lesions were performed in pig livers with radiofrequency system. SWE and B-mode images were acquired simultaneously. Liver elasticity was quantified by using SWE data and expressed in kilopascal. After the procedure, pathologic analysis of treated tissues was compared with US images. The sensitivity and positive predictive value of the SWE maps of tissue elasticity were calculated and compared with the boundaries of the pale coagulation necrosis areas found at pathology. RESULTS: The liver mean elasticity values before and after thermal therapy were 6.4 ± 0.3 and 38.1 ± 2.5 kPa, respectively (P < 0.0001). For a threshold of 20 kPa, sensitivity (i.e., the rate of pixels correctly detected as necrosed tissue) was 0.8, and the positive predictive value (i.e., the rate of pixels in the elastographic map >20 kPa that actually developed coagulation necrosis) was 0.83. CONCLUSIONS: Tissue areas with coagulation necrosis are significantly stiffer than the surrounding tissue. SWE permits the real-time detection of coagulation necrosis produced by radiofrequency and could potentially be used to monitor US-guided thermal ablation.

Monopolar radiofrequency for skin tightening: our experience and a review of the literature.

BACKGROUND: Effective nonablative skin tightening has become a reality. There are many devices that are now available. OBJECTIVE: To create a concise reference material for existing and new practitioners who wish to be updated about the available technologies. MATERIALS AND METHODS: The authors reviewed the literature from the points of view of efficacy and safety and availability. RESULTS: The increasing number of nonablative systems all seem to be effective and safe when used in the recommended manner. CONCLUSION: Radiofrequency energy can be applied to human facial, neck, and body skin to create tightening without surgical incisions and recovery time.

Effect of monopolar diathermy power settings on postoperative pain, wound healing, and tissue damage after tonsillectomy: a randomized clinical trial.

This study aimed to assess the impact of varying monopolar diathermy power settings on postoperative pain, hemorrhage, and wound healing following tonsillectomy. A single-center, prospective, randomized, double-blinded, controlled clinical study was conducted. During bilateral tonsillectomy procedures, one tonsil received low-power settings (15 W, cutting/blend) while the other tonsil received high-power settings (35 W, cutting/blend). Postoperative pain scores (0-10) and wound healing scores (0-3) were evaluated immediately after surgery and at 1, 2, and 4 weeks postoperatively using the visual analog scale. Additionally, histological analysis was performed on electrically resected tonsil tissues to assess tissue damage in the tonsil bed. The allocation of high and low power settings to each side was randomized. Results showed that 1 week after the surgery, the high-power group experienced significantly higher pain scores (mean ± standard deviation: 4.84 ± 2.21) compared to the low-power group (3.56 ± 2.24, p = 0.049). Moreover, the high-power side exhibited slower wound healing during the initial 1-2 weeks postoperatively, as indicated by lower wound scores at 2 weeks (high-power: 1.96 ± 0.64; low-power: 2.43 ± 0.59, p = 0.008). Furthermore, histological analysis revealed significantly deeper tissue degradation on the high-power side compared to the low-power side (p < 0.001), with mean depths of 565.2 ± 291.0 µm and 156.0 ± 36.8 µm, respectively. In conclusion, these findings suggest that when employing monopolar diathermy in tonsillectomy, lower power settings can lead to improved outcomes in terms of postoperative pain, wound healing, and tissue damage.Trial registration: CRIS identifier: KCT0005670 (cris.nih.go.kr, registration date: 11/12/2020).

Does unilateral laparoscopic diathermy adjusted to ovarian volume increase the chances of ovulation in women with polycystic ovary syndrome?

STUDY QUESTION: Does unilateral volume-adjusted laparoscopic diathermy increase the chances of ovulation in women with polycystic ovary syndrome (PCOS)? SUMMARY ANSWER: Although unilateral laparoscopic ovarian drilling (ULOD) using adjusted thermal doses was more efficient than bilateral laparoscopic ovarian drilling (BLOD) using fixed doses, the chances of ovulation were improved in patients irrespective of the technique used. WHAT IS KNOWN ALREADY: The adjustment of the thermal dose to ovarian volume in BLOD increases ovulation and pregnancy rates compared with fixed-dose treatment, but BLOD causes the formation of adhesions, particularly on the left ovary, and increases the risk of damage to ovarian tissue. In contrast, ULOD with a fixed thermal dose minimizes the risk of ovarian tissue damage, and can increase the activity in both right and left ovaries, although this varies in humans and in other species. STUDY DESIGN, SIZE, DURATION: This prospective, longitudinal, study, between September 2009 and January 2013, included 96 infertile women with PCOS who were unresponsive to clomiphene citrate treatment and had underwent either ULOD or BLOD. After surgery, the groups were followed up for 6 months to assess ovulatory response. PARTICIPANTS/MATERIALS, SETTING, METHODS: Patients were assigned to two groups; one group underwent laparoscopic ovarian drilling of the right ovary alone, while both ovaries were treated in the second group. The ULOD group (n = 49) received thermal doses adjusted to the volume of the right ovary (60 J/cm³). The BLOD group (n = 47) received fixed doses of 600 J per ovary, regardless of its volume. The two treatment groups were matched by the number of participants, age and baseline parameters. MAIN RESULTS AND THE ROLE OF CHANCE: The ovulation rate during the first menstrual cycle after LOD was significantly higher in the ULOD group than in the BLOD group [73 versus 49%; absolute risk reduction (ARR), -0.25; 95% confidence interval (CI), -0.44 to -0.03; P = 0.014]. Treatment with ULOD on the right ovary significantly increased the chances of ovulation in patients with a larger right ovary compared with those who had a smaller right ovary (100 versus 36%; ARR, -0.64; 95% CI, -0.84 to -0.37; P = 0.004). Interestingly, the chances of ovulation were also significantly higher in patients in the BLOD group who had a larger right ovary compared with those who had a smaller right ovary (88 versus 33%; ARR, -0.55; 95% CI, -0.73 to -0.28; P = 0.002). The pregnancy rate was also significantly higher in patients with a larger right ovary compared with those with a smaller right ovary, regardless of the treatment group. LIMITATIONS, REASONS FOR CAUTION: The 6-month follow-up was too short to demonstrate any long-term differences in the ovulation rates. Future research should therefore extend the follow-up beyond 6 months. Another limitation is that ULOD was used to treat only the right ovary. Future studies should investigate whether ULOD treatment of the larger ovary, whether left or right, would significantly increase the ovulation rate. WIDER IMPLICATIONS OF THE FINDINGS: This study represents an advance in the determination of the optimal laparoscopic treatment for women with PCOS, as it was shown that improved results can be achieved using less thermal energy in volume-adjusted ULOD.

Trans-anal rectoscopic ball diathermy (TARD) for radiotherapy-induced haemorrhagic telangiectasia: a safe and effective treatment.

AIM: Rectal bleeding may occur late after radiotherapy for prostate or bladder cancer, particularly when given by external beam, due to radiotherapy-induced haemorrhagic telangiectasia (RIHT). We present the results of trans-anal rectoscopic ball diathermy (TARD) for RIHT. METHOD: Data were collected from patients who received TARD for RIHT. The diagnosis was made during endoscopic examination. Treatment involved discretely spaced spot monopolar diathermy coagulation of the rectal mucosa to the affected areas. RESULTS: Thirteen patients [median age 76 (69-80) years] underwent TARD for RIHT between 2005 and 2008. All presented late with rectal bleeding following radiotherapy for prostate or bladder cancer. Eight were treated as a day case, four remained in hospital for one night and one was hospitalized for 2 days. There was no mortality. Eleven patients achieved excellent symptomatic control requiring no further treatment at a median follow-up of 20 (3-36) months. One patient underwent further TARD for recurrence. One patient complained of severe anorectal pain of no obvious cause and one developed constipation. CONCLUSION: Trans-anal rectoscopic ball diathermy (TARD) is a safe and effective treatment for patients with rectal bleeding due to RIHT.

Cold versus hot tonsillectomy: state of the art and recommendations.

An investigation of the risk factors for haemorrhage after tonsillectomy with particular reference to the use of bipolar diathermy for tonsillar dissection and haemostasis, diathermy power settings and coblation tonsillectomy. The findings of the National Prospective Tonsillectomy Audit and subsequent related research are summarised and discussed with reference to the issue of use of hot versus cold tonsillectomy techniques. Additional unpublished data on coblation tonsillectomy is presented. Overall, increased haemorrhage rates were noted for diathermy dissection tonsillectomy (adjusted odds ratio 2.47, p < 0.0001) and coblation tonsillectomy (adjusted odds ratio 3.07, p < 0.0001) compared to the reference category of cold steel tonsillectomy. Use of bipolar diathermy for haemostasis only carried an intermediate risk of haemorrhage (adjusted odds ratio 1.57, p = 0.004). Further investigation of diathermy power settings demonstrated a quantitative relationship between increasing power usage and subsequent haemorrhage. Use of diathermy for haemostasis at the lowest effective setting may carry a comparable risk of haemorrhage to that of cold steel tonsillectomy. Recommendations are given on the optimum tonsillectomy technique for both the older child or adolescent and the particularly young or low weight child.

Trichloroacetic acid application versus spray monopolar diathermy for treating benign cervical lesions: a randomized controlled clinical trial.

OBJECTIVE: This study aimed to compare efficacy, tolerability, and safety of trichloroacetic acid (TCA) painting versus monopolar spray coagulation of the cervix for treating persistent benign cervical lesions. MATERIALS AND METHODS: A prospective randomized controlled trial was done in a tertiary care referral facility and university hospital. A total of 246 cases with objective evidence of benign cervical lesions were divided into 2 groups according to the line of management. Group A was composed of 126 cases subjected to spray monopolar coagulation, whereas group B was composed of 120 cases subjected to TCA application. Cervical smearing and colposcopy with or without cervical biopsy were performed to exclude underlying malignant lesions. Trichloroacetic acid painting or spray monopolar coagulation of the benign cervical lesion(s) was also performed. Follow-up was performed to assess relief of symptoms and cervical morphology for 1 month. Main outcome measures include success of management tool, relief of symptoms, and normal cervical morphology after 1 month of therapy. RESULTS: A statistically significant cure rate of cervical lesions after treatment in both groups without significant difference between both groups was reported. Failure rate was reported more in group B than group A mainly owing to hypertrophied ectopy and cervical polyp. Patient in group A reported low satisfaction (26.9%) and poor tolerability rate (44.5%) as compared with patients in group B, who reported high satisfaction (77.5%) and good tolerability rate (77.5%), this difference was statistically significant. CONCLUSIONS: Both topical application of 70% TCA and monopolar spray coagulation offer considerable efficacy, acceptable success rates, and minimal complications. Spray coagulation is significantly superior in terms of less persistent or incompletely healed lesions. Nevertheless, topical application of 70% TCA has the advantages of simplicity, higher patient tolerability, and safety, which can be widely used by gynecologists who have limited experience with surgical procedures. It is highly recommended if the cervical lesion is ectopy or nonspecific cervicitis but not hypertrophic lesion such as hypertrophic ectopy or polyp.

[Ligasure vs conventional diathermy in excisional haemorrhoidectomy: a retrospective study of a single center]. / Hemorroidectomía con Ligasure vs diatermia convencional: análisis retrospectivo monocéntrico.

INTRODUCTION: Hemorrhoids are a prolapse of vasculopathic structures that cushion the anal canal and haemorrhoidectomy is the most effective treatment for grades III and IV In this retrospective study we compare the outcome after haemorrhoidectomy with Ligasure or with conventional diathermy. METHODS: From June 2005 to March 2009 we analyzed 75 patients affected by hemorrhoids (grades III and IV) who underwent haemorrhoidectomy in the University Hospital Arnau de Vilanova in Lleida. We evaluated the technique, the age and the sex, and compared the post-operative hospital stay, the post-operative pain and the complications with each of the techniques. RESULTS: We used Ligasure technique in 49 patients (65%) and conventional diathermy technique in 26 (35%). The mean age was 50.3 years. There was no significant difference in both postoperative length ofstay, with an average of2.13 days (P = 0.60), and postoperative pain in the first 15 days (P = 0.275). On the contrary, we found a significant difference in the rate of postoperative complications (P = 0.032) and in the post-surgical pain at one month (P = 0.03). CONCLUSIONS: In our experience the Ligasure haemorrhoidectomy has shown to have fewer complications and post-operative pain when compared with conventional diathermy haemorrhoidectomy.

Systematic review and meta-analysis of cutting diathermy versus scalpel for skin incision.

BACKGROUND: Skin incisions have traditionally been made using a scalpel. Cutting diathermy, a more recent alternative, is thought to increase the risk of infection, impair healing and decrease cosmesis. Recent studies suggest otherwise, claiming that diathermy may offer potential advantages with respect to blood loss, incision time and postoperative pain. The aim of this meta-analysis was to compare skin incisions made by either scalpel or cutting diathermy. METHODS: A systematic literature search and review was performed for studies published from January 1980 until June 2011. Randomized clinical trials comparing scalpel and cutting diathermy for skin incisions of any operation were included. Primary outcomes included wound complication rate, blood loss, incision times and pain scores. RESULTS: Fourteen randomized trials met the criteria for inclusion in the meta-analysis, providing outcome data for a total of 2541 patients (1267 undergoing skin incision by cutting diathermy and 1274 by scalpel). The median length of follow-up across all studies was 6 weeks (range 4 days to 19 months). Compared with a scalpel incision, cutting diathermy resulted in significantly less blood loss (mean difference 0.72 ml/cm(2); P < 0.001) and shorter incision times (mean difference 36 s; P < 0.001), with no differences in the wound complication rate (odds ratio 0.87; P = 0.29) or pain score at 24 h (mean difference 0.89; P = 0.05). CONCLUSION: Skin incisions made by cutting diathermy are quicker and associated with less blood loss than those made by scalpel, and there are no differences in the rate of wound complications or postoperative pain.
