Comparative study of safety and efficacy of electrocautery blade with cold scalpel blade for skin opening during fixation of fracture of forearm bone with plate and screws

Background: Skin incisions have usually been made using a scalpel. Electrocautery, a more recent alternative, is thought to increase the risk of infection, impair healing and decrease cosmesis. Recent studies suggest that electrocautery may offer potential advantages with respect to blood loss, incision time and postoperative pain.Objective: The aim of this study was to compare the efficacy and safety of electrocautery incisions versus conventional scalpel incisions in orthopedic surgeries using internal implants.Method: The study was conducted as a prospective one in a tertiary care center in the Department of Orthopaedics, BPKIHS, Dharan, Nepal. Patients with closed fracture of the forearm bones admitted for surgery from April 2014 to September 2014 was included in the study. Each incision was divided into two halves, proximal half to be opened by steel scalpel blades and the distal half to be opened by an electrocautery blade. Proximal half and distal half of incision were compared on operating day and on days 2, 14 and again on 6 weeks and 3 month.Result: A total of 60 patients were enrolled in the study. Forearm skin incisions using electrocautery were significantly quicker than scalpel incisions (p<0.05). Postoperative wound complication rates did not differ significantly between the Scalpel and Electrocautery groups (p>0.05).Conclusion: There is no difference in healing of two halves of skin incision made by electrocautery and scalpel in orthopedic surgeries using internal implants.Health Renaissance 2015;13(2): 43-49

Intravascular application of electrocautery in a rabbit model of abdominal aortic endarterectomy.

Effective therapies for preventing perioperative complications such as thrombosis and inflammation after coronary endarterectomy (CE) are lacking. Electrocoagulation electrotomes have been routinely used in surgery for their cutting, clotting, and hemostatic properties. As strong flattening tools, their electrocautery function may prevent mechanical intimal-adventitial injury to arterial circulation and attenuate stenosis. The present study investigated the effects of intravascular application of electrocautery on ameliorating inflammation and thrombosis in a rabbit model of abdominal aortic endarterectomy. New Zealand rabbits were randomly divided into the sham, control (endarterectomy), and study (endarterectomy + electrocautery) groups with 10 in each group. Abdominal aortas were partially blocked and intima was removed. Electrocautery was performed with an electrocoagulation electrotome through the entire blocked vessel lumen. Vascular ultrasound parameters, molecular biological and histological characteristics of the abdominal aorta including vascular diameter, blood flow velocity, serum interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) levels, and apoptosis rate of vascular endothelial cells (ECs) were evaluated postoperatively by vascular Doppler ultrasound, ELISA, real-time RT-PCR, flow cytometry, and immunofluorescence at various time points. Compared with the endarterectomy + electrocautery group, the isolated endarterectomy group had significantly increased levels and gene expression of TNF-α and IL-6 (P<0.05), and rates of apoptosis of vascular ECs (P<0.05), with gradual vascular stenosis and decreased blood flow velocity. In conclusion, intravascular application of electrocautery has favorable short-term effects on the abdominal aorta and can reduce inflammation in a rabbit model of abdominal aorta endarterectomy. Long-term anti-inflammatory and anti-thrombotic effects on arterial remodeling and the clinical value of electrocautery in CE remain to be determined.

A Comparative Study of the Use of Harmonic Scalpel versus Unipolar Cautery in Modified Radical Mastectomy.

Context:Oncosurgery is an emerging branch with the set goals of prolonging the life and ensuring the best possible quality of life to the surviving patient. The use of harmonic scalpel has proved to be beneficial in a variety of surgeries but its role in breast surgery is still controversial.Aims:We conducted this study to compare the intraoperative and postoperative outcomes in modified radical mastectomy using harmonic scalpel versus electrocautery.Subjects and Methods:Fifty female patients with confirmed diagnosis of breast carcinoma and planned for modified radical mastectomy were taken up for surgery. Twenty-five patients were operated using harmonic scalpel (Group A) and another 25 were operated using unipolar cautery (Group B).Results:The mean operative time was significantly longer with harmonic scalpel when compared to that with electrocautery (140.40 ± 29.96 vs. 99.80 ± 24.00 min, P < 0.001). The smaller amount of drainage content (431.60 ± 145.94 vs. 594.20 ± 278.63, P = 0.013) and intraoperative blood loss (426.00 ± 76.54 vs. 502.00 ± 104.56, P = 0.005) in the group operated with the ultrasound harmonic scalpel was statistically significant. There was no significant difference between the groups with regard to drain duration (5.24 ± 0.97, P = 0.127), seroma (12% vs. 16%, P = 0.684), hematoma (4% vs. 4%, P = 1.000), wound infection (24% vs. 32%, P = 0.529), flap necrosis (8% vs. 28%, P = 0.066), pain intensity (measured on visual analog scale) (5.08 ± 1.29 vs. 5.20 ± 1.68, P = 0.778), and lymphedema (4% vs. 8%, P = 0.552). The length of hospital stay could not be compared effectively because all the patients were discharged on the 10th or 11th postoperative day. The cost of the equipment used in the electrocautery group was almost negligible as compared to the harmonic group.Conclusions:The use of harmonic scalpel versus electrocautery is somewhat advantageous but not cost-effective.

Seroma formation after modified radical mastectomy

Background Modified radical mastectomy remains the most commonly performed surgery for breast cancer. Aim of the work The aim of this study was to evaluate the effect of different methods (conventional scalpel, electrocautery, and harmonic scalpel) of breast dissection during mastectomy on seroma formation. Patient and methods This study was conducted in Al-Azhar University Hospital in Assiut from April 2013 to April 2016, on 110 female patients aged from 25 to 70 years; all patients were having stage II breast cancer, according to the Manchester and International Union against Cancer (TNM). Modified radical mastectomy was done after complete preoperative assessment. Result One-hundred and ten female patients have stage II breast cancer aged from 25 to 70 years. During the modified radical mastectomy, in this study, the breast dissection was done by electrocautery in 42 patients, using conventional scalpel in another 42 patients and using harmonic scalpel in the remaining 26 patients. At the end of this study, there were 15 cases (out of 110 patients) of postmastectomy seroma detected postoperatively, only one case in the conventional scalpel group, 14 cases in the electrocautery group and no case in the harmonic scalpel group. The wound drains were removed in all cases on day 7postoperatively. In all patients of this study, a pressure garment was used postoperatively. Conclusion The use of harmonic scalpel in breast dissection is better than electrocautery use as regards postmastectomy seroma formation. If harmonic scalpel is not available, it is better to use the conventional scalpel.

Neck dissection with harmonic scalpel and electrocautery? A randomised study

ObjectiveIs the use of harmonic scalpel for neck dissection useful? Literature search did not show a single, prospective, randomised control trial. We intended to study the role of harmonic scalpel in neck dissection and compare it with conventional electrocautery technique for oral cavity carcinoma. Methods40 patients undergoing selective neck dissection for primary oral cavity malignancy were enrolled in this study. The harmonic scalpel (HS) group consisted of 20 patients, and the electrocautery technique (ET) group comprised of 20 patients. The following variables were examined: intraoperative blood loss, operative time, number of ligatures used, postoperative drain, and postoperative hospital stay. ResultsIntraoperative blood loss was found to be significantly reduced in harmonic scalpel group as compared to electrocautery group. However, we found no difference in other parameters like operative time, postop drain, postoperative hospital stay and number of ligatures used between both groups. ConclusionHarmonic scalpel for neck dissection is associated with significantly lesser intraoperative blood loss as compared to electrocautery. There is no effect on operative time and postoperative hospital stay in both groups.

Comparison of spinal accessory dysfunction following neck dissection with harmonic scalpel and electrocautery – A randomized study

IntroductionHarmonic scalpel is being increasingly used in neck dissection as alternative to conventional electro-cautery for achieving haemostasis. Use of harmonic scalpel has been shown to significantly reduce intra operative blood loss and intra operative time in neck dissection. But how safe is it with regards to nerve injury (spinal accessory nerve and other nerves) during neck dissection. We intended to study the spinal accessory nerve injury during neck dissection by both harmonic scalpel and electro cautery technique and compared postoperative recovery of shoulder function after neck dissection. Methods40 patients undergoing selective neck dissection for primary oral malignancy were enrolled in this study. The Harmonic scalpel (HS) group consisted of 20 patients, and the electo cautery technique (ET) group had 20 patients. The following variables were examined: shoulder pain by visual analog scoring and shoulder function by means of degree of abduction and graded was grade I-0–90°; grade II-90–135°; grade III-135–180°. They assessment was done at the time of discharge, 1month and 3month and six month after surgery. ResultsThough shoulder pain was almost similar at 1st week and 1month, however at 2nd and 6th month shoulder pain was found to be significantly lesser in harmonic scalpel group as compared to electro cautery. At 1week more no of patients had restricted shoulder mobility in HS as compared to EC group. But at 6months the shoulder function was found to be significantly better in HS group as compared to EC group (p value<0.05). ConclusionSpinal accessory nerve function recovery after selective neck dissection is better in HS group as compared to the electro cautery group.

Comparison of Radiofrequency and Electrocautery With Conventional Scalpel Incisions

The disadvantages of conventional scalpels, including insufficient control of bleeding, prompted us to search for new alternative methods such as electrosurgery and radiosurgery. In this study, the conventional scalpel was compared with radiosurgery and electrosurgery for wound healing with assessment of lateral heat production, inflammation, and instrument performance. Incisions were made in the palatal mucosa of 42 Wistar rats using a scalpel, electrocautery instrument, or radiofrequency instrument. Postoperative hemostasis, tissue coagulation, and tissue sticking were measured, and pain evaluation through weight loss was recorded. Gingival biopsy specimens from the surgical area were obtained at the time of surgery and 2, 4, 7, and 14days postoperatively and were evaluated immunohistochemically for inducible nitric oxide synthase and heat shock protein 70. Kruskal-Wallis, 1-way analysis of variance, and Mann-Whitney U tests were used for statistical evaluation. The rats in the electrosurgery and radiosurgery groups had aggressively greater weight loss when compared with the scalpel group in the first 7days. Hemostasis was better in the electrocautery group, tissue coagulation was greater in the radiofrequency group (P < .001), and tissue sticking was lesser in the scalpel group (P < .001) compared with the other groups. Inducible nitric oxide synthase expression and heat shock protein 70 expression were similar in all 3 groups. Electrosurgery performed better regarding hemostasis, whereas a scalpel was superior in terms of tissue sticking and tissue coagulation. Radiosurgery was superior regarding hemostasis when compared with a conventional scalpel, but it was not as successful as electrosurgery.

Reduced blood loss and operation time in lumbar posterolateral fusion using a bipolar sealer.

A bipolar sealer using Transcollation® technology, a combination of radiofrequency energy and saline, can provide hemostasis at 100°C, which is lower than that used in standard electrocautery. Previous studies of joint arthroplasty have shown that use of the bipolar sealer reduces blood loss and tissue damage during the operation. However, it is unknown whether a bipolar sealer reduces blood loss and tissue damage in lumbar posterolateral fusion (PLF) surgery. The purpose of this study was to analyze the efficacy of this device in limiting blood loss during exposure of the lumbar spine in the treatment of PLF and postoperative pain. Fifty patients who underwent PLF were prospectively enrolled between October 2011 and March 2013. Twenty-five patients were randomized to the bipolar sealer group (BS group) and 25 patients to the standard electrocautery group (control group). Operative time and blood loss during exposure of posterior bony elements including the transverse process for PLF, visual analog scale (VAS) to quantify postoperative pain, and the interval from the surgery to hospital discharge were compared. Operative time and blood loss expressed per level of exposure were significantly lower in the BS group than in the control group. There was a tendency toward a lower VAS at postoperative week 1 in the BS group. The duration of hospitalization was 15 and 26days in the BS and control groups, respectively. A large randomized control trial adjusted for the number of fusion levels and body mass index is required to confirm the novelty value of this new bipolar sealers.

Preventive effects on seroma formation with use of the harmonic focus shears after breast reconstruction with the latissimus dorsi flap

Background: Postoperative seroma is the most common complication of latissimus dorsi (LD) flap surgery for breast reconstruction. The use of EC for elevation of the flap might cause additional risk for seroma formation by injuring surrounding lymph vessels due to heat dispersion. There is a possibility that seroma formation can be prevented by using alternative devices such as harmonic focus (HF) shears that can dissect the tissue simultaneously with sealing the lymph vessels.Methods: Forty-eight patients who underwent breast reconstruction with LD flaps since August 2011 up to April 2015 were enrolled. They were retrospectively split into two groups: 24 in group HF, 24 in group EC (conventional electrocautery). The primary outcome measures were rate of seroma formation and total volume of drain discharge and indwelling period of drainage at the anterior chest and donor site. Secondary outcome measures were length of hospital stay and duration of surgery.Results: The incidence of seroma was 45.8% in the EC group and 20.8% in the HF group. The total volumes of the drain discharge and indwelling period of drainage in the back (donor site) were significantly decreased in the HF group. The length of the hospital stay and surgical time was significantly shorter for the HF group.Conclusions: The use of HF shears on the LD flap donor site is helpful for reducing seroma formation, the length of the drainage period, the surgical time, and the length of the hospital stay.

Free Flap Elevation Times in Head and Neck Reconstruction Using the Harmonic Scalpel Shears.

Summary:Free tissue transfer has become the mainstay of head and neck cancer (HNC) reconstructive surgery. The objective of the study is to examine the efficacy of the Harmonic Scalpel (HS) Shears on free flap elevation time and complication rates after HNC reconstruction compared with traditional electrocautery. A retrospective review of 215 HNC patients undergoing surgical ablation and free flap reconstruction from January 2010 to April 2013 at the University of Alberta Hospital was undertaken. All patients requiring free flap reconstruction with radial forearm free flap or fibula free flap were included. Overall, there was no significant difference demonstrated between the HS and electrocautery groups for free flap elevation time for RFFFs (P = 0.563) or FFFs (P = 0.087). No differences were observed in donor-site complications. The HS is a reliable, safe, and alternative method of free flap elevation in HNC reconstructive surgery.

Health-Related Quality of Life and Sexual Functioning of HIV-Positive Men Who Have Sex With Men Who Are Treated for Anal Intraepithelial Neoplasia.

The impact of the treatment of precursor lesions of anal cancer (anal intraepithelial neoplasia) on health-related quality of life has not been investigated. This study aimed to evaluate the impact of 3 treatment options for anal intraepithelial neoplasia on health-related quality of life and sexual functioning in HIV-positive men who have sex with men. The prospective cohort was embedded in a randomized clinical trial evaluating the optimal treatment of anal intraepithelial neoplasia. This study was performed at the HIV outpatient clinic of the Academic Medical Center, Amsterdam, the Netherlands. Included in the study were HIV-positive men who have sex with men with anal intraepithelial neoplasia. Treatment with imiquimod (n = 54), topical fluorouracil (n = 48), or electrocautery (n = 46) was given for 16 weeks. Health-related quality of life and sexual functioning were assessed before, during, and 4 weeks after treatment. Health-related quality of life was assessed using the EQ5D, sexual functioning was assessed using items derived from the International Index of Erectile Function, and the female sexual function index adapted for anal intercourse. One hundred forty-five patients (98%) completed at least 1 questionnaire. There was a significant different pattern of change over time in health-related quality of life among the 3 treatment groups. Patients in the imiquimod group were more likely to report pain/discomfort at week 8 than patients in the electrocautery group. Patients in the electrocautery group were more likely to report anxiety/depression and were less satisfied with their overall sex life at week 16 than patients in the imiquimod and fluorouracil groups, and patients in the electrocautery group were also more likely to report pain/discomfort and problems with usual activities at week 20 than patients in the fluorouracil group. The follow-up method differed slightly among treatment groups. There is no standardized, validated sexual functioning questionnaire for HIV-positive men who have sex with men. All treatment options have a negative impact on aspects of health-related quality of life. Electrocautery has significantly more negative effects on health-related quality of life than imiquimod and fluorouracil and also has a negative effect on sexual functioning.

Electrocautery vs non-electrocautery dilation catheters in endoscopic ultrasonography-guided pancreatic fluid collection drainage.

To investigate the safety and utility of an electrocautery dilation catheter for endoscopic ultrasonography (EUS)-guided pancreatic fluid collection drainage. A single-center, exploratory, retrospective study was conducted between August 2010 and August 2014. This study was approved by the Medical Ethics Committee of our institution. Informed, written consent was obtained from each patient prior to the procedure. The subjects included 28 consecutive patients who underwent EUS-guided transmural drainage (EUS-TD) for symptomatic pancreatic and peripancreatic fluid collections (PFCs) by fine needle aspiration using a 19-gauge needle. These patients were retrospectively divided into two groups based on the use of an electrocautery dilation catheter as a fistula dilation device; 15 patients were treated with an electrocautery dilation catheter (electrocautery group), and 13 patients were treated with a non-electrocautery dilation catheter (non-electrocautery group). We evaluated the technical and clinical successes and the adverse events associated with EUS-TD for the treatment of PFCs between the two groups. There were no significant differences in age, sex, type, location and diameter of PFCs between the groups. Thirteen patients (87%) in the electrocautery group and 10 patients (77%) in the non-electrocautery group presented with infected PFCs. The technical success rates of EUS-TD for the treatment of PFCs were 100% (15/15) and 100% (13/13) for the electrocautery and the non-electrocautery groups, respectively. The clinical success rates of EUS-TD for the treatment of PFCs were 67% (10/15) and 69% (9/13) for the electrocautery and the non-electrocautery groups, respectively (P = 0.794). The procedure time of EUS-TD for the treatment of PFCs in the electrocautery group was significantly shorter than that of the non-electrocautery group (mean ± SD: 30 ± 12 min vs 52 ± 20 min, P < 0.001). Adverse events associated with EUS-TD for the treatment of PFCs occurred in 0 patients and 1 patient for the electrocautery and the non-electrocautery groups, respectively (P = 0.942). EUS-TD using an electrocautery dilation catheter as a fistula dilation device for the treatment of symptomatic PFCs appears safe and contributes to a shorter procedure time.

A comparative study to evaluate the outcome between electrocautery versus scalpel skin incision in tension free inguinal hernioplasty: a tertiary care teaching centre experience

Background: The use of cutting electrocautery instead of scalpel for skin incision is still suboptimal worldwide. There are many studies which include its use in general surgical operations but without use of prothetic material mostly, so our study aimed at its use in operations which include use of prosthetic material during abdominal wound closure means in tension free inguinal hernioplasty, exclusively. The objective of this study was to evaluate whether the application of extreme heat by cutting electrocautery may result in significant postoperative pain and poor wound healing with increased risk of wound infection in presence of underlying prosthetic material and poor cosmesis because of excessive tissue damage and scarring respectively as per previous hypothesis or it’s safe and effective instead. Methods: This is a retrospective clinical study conducted in the Department of Surgery, of a teaching tertiary care hospital in Sola, Ahmedabad between May 2013 to April 2014. Patients were allocated consecutively to have either scalpel or cutting electrocautery incisions. The duration used in making the skin incision; the incisional blood loss and the ensuing length and depth of the wound were noted. Postoperative pain; duration of wound healing and the occurrence of surgical site infection and cosmetic outcome were also noted. Results: A total of 196 consecutive patients included to inguinal hernioplasty using the tension-free technique and fulfilling the inclusion criteria for the study were allocated alternately to either electrocautery (n=98) or scalpel (n=98) groups. The ages ranged from 16 to 73 years. The demography, case distribution and body mass index were similar in both groups. The incision time was shorter in the electrocautery group (P <0.001). The blood loss was less with the electrocautery compared to the scalpel (6.53±3.84 ml vs. 18.16±7.36 ml, P<0.001). The cumulative numerical rating scale score for pain was 12.65 (standard deviation SD 8.06) and 17.12 (SD 9.49) in the diathermy and scalpel groups respectively (P<0.001). There was no statistically significant difference in wound infection and wound closure (epithelialization time) (P=0.206). Conclusions: The use of cutting electrocautery in making skin incision during inguinal hernioplasty is as safe as scalpel in terms of wound healing and cosmesis and is also associated with reduced incision time, incisional blood loss, and postoperative pain.

Long-term outcomes in medial flap inferior turbinoplasty are superior to submucosal electrocautery and submucosal powered turbinate reduction.

Techniques for inferior turbinate reduction vary from complete turbinectomy to limited cauterization. Surgical methods differ on the degree of tissue reduction and reliance on surgical tissue removal vs tissue ablation. The outcome and morbidity from 3 different turbinate techniques are compared. A randomized double-blinded study was performed. Patient nasal cavities were randomized to different interventions on each side within the same patient. One group had a combination of submucosal powered turbinate reduction (designated "submucosal") and submucosal electrocautery (designated "electrocautery"); and the second group had a combination of submucosal powered turbinate reduction (designated "submucosal") and medial flap turbinoplasty (designated "turbinoplasty"). Patient-scored nasal obstruction and rhinorrhoea (1 to 5) along with blindly assessed nasal airway patency ratings (1 to 4) was done at 12 and 60 months postoperatively. Pain requiring additional analgesia, crusting, bleeding (needing review), and revision were documented. A total of 100 patients were recruited (age 32.79 ± 13.58 years; 39% female). This represented 200 nasal airway surgeries with 100 submucosal procedures, 50 electrocautery and 50 medial flap turbinoplasties. No patients complained of worsening of their obstruction. At 60 months patients in the turbinoplasty group had greater outcomes, with 90.2% having occasional or no decongestant use (Kendall's tau B p < 0.001) compared to electrocautery (15.8%) and submucosal (37.8%). Fewer turbinoplasty patients had a revision procedure (12%, χ(2) = 20.08, p < 0.001) compared to electrocautery (54%) and submucosal (40%). Crusting was more common in the electrocautery group (58% vs submucosal 2% and turbinoplasty 0%; χ(2) = 92.04; p < 0.001). The medial flap turbinoplasty provided consistent, robust results. Long-term relief of obstructive symptoms without additional risk of complication was observed in the turbinoplasty group.

Harmonic Scalpel Versus Electrocautery in Axillary Dissection in Carcinoma Breast.

To compare the results between harmonics scalpel and electrocautery use in axillary dissection for carcinoma breast. Randomized controlled trial. Department of Surgery, Services Hospital, Lahore, from December 2013 to June 2014. Eighty patients fulfilling the inclusion criteria were selected and equally divided in two groups. Axillary dissection for carcinoma breast was performed by using the harmonic scalpel in one group and by using electrocautery in the other group. Total mean axillary drain output and frequency of axillary numbness were noted in both groups and compared. All the patients were females with mean age of 53.52 ± 9.8. Mean axillary drain output in harmonic scalpel group was 167.75 ± 43.90 as compared to 310.00 ± 60.09 in electrocautery group while only 12.5% of patients were positive for axillary numbness in harmonic scalpel group as compared to 100% of patients who were positive for electrocautery group. Use of harmonic scalpel in axillary dissection resulted in decreased total mean axillary drain output and lowered frequency of axillary numbness when compared to utilizing electrocautery.

Prospective control study using fibrin sealants and Harmonic® scalpel in Latissimus Dorsi flap transfer

Background: Latissimus dorsi flap (LD) is used in breast reconstruction procedures, although prolonged donor site drainage is a frequent complication. To decrease this problem, quilting sutures and/or fibrin sealants were proposed, with alternate results. The primary objective of this study was to assess the effectiveness of Tisseel® in association with the Harmonic Synergy® blade system to reduce this complication. Materials and methods: Between 2010–2012, 20 consecutive patients undergoing immediate unilateral breast reconstruction with LD were enrolled in the study (Group A) and matched with 20 patients in which LD was raised with electrocautery (Group B), and 20 patients in which LD was harvested with Harmonic® (Group C). After informed consent acquisition, Harmonic® was used in Group A for LD harvesting, but differed from other groups as fibrin glue was applied to the donor site prior to closure. In all groups donor site drainage measurements at 24 and 48 hours, total drain volume, days to drain removal, operation time, and complication rate were recorded. Pearson’s Chi-squared, ANOVA, and Bonferroni post-hoc tests were used to analyze the data. Results: Data analysis did not show any statistical difference. Prolonged drains output ≥ 15 days occurred in one patient of Group A and C, and in three Group B patients. Conclusion: Although the combined use of Harmonic® and Tisseel® presents a low donor site fluid collection rate, the fibrin glue seems not to have further beneficial effects in reducing the post-operative serous drainage or to lead to an early drain removal when compared to Harmonic® only.

Tunical Outer Layer Plays an Essential Role in Penile Veno-occlusive Mechanism Evidenced from Electrocautery Effects to the Corpora Cavernosa in Defrosted Human Cadavers

To determine the exact anatomical structure for establishing penile veno-occlusive function, we sought to conduct a hemodynamic study on defrosted human cadavers. Thirteen penises were used for this experiment, and 11 intact penises were allocated into the electrocautery group (EG, n = 6) and the ligation group (LG, n = 5). A circumcision was made on the penis to access the veins. Two #19 scalp needles were fixed in the 3 and 9 o'clock positions in the distal penis for colloid infusion and intracavernous pressure (ICP) monitoring, respectively. For the EG, the deep dorsal vein and cavernosal vein trunks were freed for 3-5 cm where at least 3 emissary veins were identified via opening Buck's fascia; these veins underwent electrocautery at 45 watts, while the ICP was maintained at 0, 50, 75, 100, 125, and 150 mmHg, respectively. For control, venous ligation was made but at the ICP of 150 mmHg. A tissue block including the emissary vein was then obtained for histological analysis. Except all in the EG and those whose ICP exceed 125 mmHg in the EG, the sinusoids of the corpora cavernosa sustained varied fulgurated fibrosis in every specimen and the severity appeared reversely commensurate with the ICP regarding sinusoidal clumping and darkish bands (P <.02 and .01 respectively). We conclude that the tunica albuginea can prevent the electrocautery damage to intracavernous sinusoids once the ICP reached a level corresponding to a rigid erection. The outer tunica plays an essential role in fulfilling the veno-occlusive mechanism.

Ultrasonic Technology Decreases Wound Complications in Groin Dissection for Vascular Procedures

Methods: A retrospective analysis of prospectively collected data from a single institution (Stony Brook University Medical Center) using the Vascular Quality Initiative database was performed. The research protocol was defined prior to initiating data collection. Included were consecutive pa- tients who underwent groin dissection with either electrocautery (group A) or ultrasonic devices (group B) during the following procedures: endovascu- lar aortic aneurysm repair, thoracic endovascular aortic aneurysm repair, lower extremity bypass, or hybrid peripheral vascular intervention. In-hospi- tal and outpatient records were reviewed to capture postoperative surgical site complications, and clinical outcomes were compared between the groups. Results: Over a 24-month period, 233 patients underwent peripheral vascular interventions that required 346 groin dissections. There were no significant differences in the risk profile of the patients between group A (n ¼ 135) and group B (n ¼ 98). Wound complications (hematoma, infec- tion, dehiscence, lymphocutaneous fistula, and seroma/lymphocele) occurred significantly less often in the ultrasonic group (group B: 7.2%) compared with the electrocautery group (group A: 28.5%; P < .0001). When looking at specific wound complications, use of the ultrasonic energy device significantly decreased the rate of lymphatic complications (2.1% vs 14.6%; P < .01) and wound dehiscence (0% vs 7%; P ¼ .01). Conclusions: The use of the ultrasonic energy device (Harmonic), when compared with electrocautery (Bovie) in surgical dissection of the groin, is associated with a lower rate of wound complications, specifically lymphatic leaks and wound dehiscence. Routine use of this alternative tool may help decrease surgical site complications in this particularly vulner- able area.

Comparison of electrocautery incision with scalpel incision in midline abdominal surgery – A double blind randomized controlled trial

Aim &objectivesTo compare the electrocautery incision with scalpel incision in patients undergoing abdominal surgery using a midline incision with respect to incision time, blood loss during incision, postoperative incision site pain and wound infection. MethodsPatients undergoing midline abdominal surgery were randomized into electrocautery and scalpel groups. The incision dimensions, incision time and blood loss during incision were noted intraoperatively. Postoperative pain and wound infection were recorded on every postoperative day for one week. Results41 patients in each of the two groups were analyzed. Gender and age distribution was similar in both the groups. The mean incision time per unit wound area in the electrocautery group and scalpel group was 9.40 ± 3.37 s/cm2 and 9.07 ± 3.40 s/cm2 (p = 0.87) respectively. The mean blood loss per unit wound area was significantly lower in the electrocautery group at 6.46 ± 3.94 ml when compared to that of 23.40 ± 15.28 ml in the scalpel group (p= < 0.0001, CI = 11.97–21.89). There was no significant difference in pain on any of the postoperative days between the two groups and there was no significant difference in the wound infection rates between the electrocautery and scalpel groups (14.63% vs. 12.19%; p = 0.347). ConclusionWith a comparable Postoperative incision site pain, wound infection rate and significantly lower blood loss with the equal time taken for the incision, electrocautery can be considered safe and effective in making skin incision in midline laparotomy compared to scalpel incision.

Diathermy versus Scalpel Incision in a Heterogeneous Cohort of General Surgery Patients in a Nigerian Teaching Hospital.

Background:The anecdotal fear of using cautery for surgical incisions is still common in surgical practice despite recent evidences. The aim of this study is to compare the results of electrocautery and the scalpel in skin incisions.Materials and Methods:This is a prospective randomized double blind study conducted in the Department of Surgery, of a teaching hospital in Ibadan. Patients were randomized to have either scalpel or electrocautery incisions. The duration used in making the skin incision; the incisional blood loss and the ensuing length and depth of the wound were noted. Postoperative pain; duration of wound healing and the occurrence of surgical site infection were also noted.Results:There were 197 patients consisting of the scalpel group (n = 98) and the electrocautery group (n = 99). The ages ranged from 16 to 73 years. The demography, case distribution and body mass index were similar in both groups. The mode of presentation was predominantly elective. The incision time was shorter in the electrocautery group (P < 0.001). The blood loss was less with the diathermy compared to the scalpel (6.53 ± 3.84 ml vs. 18.16 ± 7.36 ml, P < 0.001). The cumulative numerical rating scale score for pain was 12.65 (standard deviation [SD] 8.06) and 17.12 (SD 9.49) in the diathermy and scalpel groups respectively (P < 0.001). There was no statistically significant difference in wound infection and wound closure (epithelialization time) (P = 0.206).Conclusion:The use of electrocautery in making skin incision is associated with reduced incision time, incisional blood loss, and postoperative pain.
