Abstract
OBJECTIVE To characterize adverse events, provide a safety profile, and understand patient outcomes after complications arising from LigaSure and Harmonic use in the head and neck region. METHODS Retrospective analysis of adverse events from the Manufacturer and User Facility Device Experience (MAUDE) between January 2013 and 2023. RESULTS A total of 158 LigaSure and 159 Harmonic events were extracted. There were significantly more reports of Harmonic device overheating (6.9% vs. 0.6%, p = 0.003) and spontaneous self-activation (4.4% vs. 0%, p = 0.032). Although intra-operative and post-operative complications were similar among both groups, there were significantly more intra-operative bleeding events for LigaSure as compared to Harmonic (8.2% vs. 0.0%, p = 0.001). CONCLUSION Understanding technical complications and adverse events attributable to LigaSure and Harmonic devices enables the development of clinically relevant risk mitigation strategies. Surgeons should avoid improper use by remaining vigilant of device functionality and temperature changes.

Kajiwara M, Fujikawa T, Hasegawa S. Tissue pad degradation of ultrasonic device may enhance thermal injury and impair its sealing performance in liver surgery. World J Hepatol 2022; 14:1357-1364. [PMID: 36158911 PMCID: PMC9376783 DOI: 10.4254/wjh.v14.i7.1357] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/11/2022] [Revised: 04/12/2022] [Accepted: 07/06/2022] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Ultrasonic devices are widely used in many surgical fields, including hepatectomy; however, the negative effects of tissue pad degradation of ultrasonic devices, including those in liver surgery, remain unknown. The Harmonic® 1100 (H-1100) scalpel has advanced heat control technology than previous models, such as the Harmonic® HD1000i (H-HD1000i). We hypothesized that, because of its advanced temperature-control technology, the H-1100 scalpel would show less tissue pad degradation, resulting in superior sealing performance, compared to that with the H-HD1000i scalpel.
AIM To elucidate ultrasonic device tissue pad degradation effects on instrument temperature and sealing performance using ex vivo porcine liver/vessel models.
METHODS Two different harmonic scalpels were used and compared: A newer model, the H-1100 scalpel, and an older model, the H-HD1000i scalpel. Using ex vivo porcine livers, each instrument was activated until the liver parenchyma was dissected. The device temperature (passive jaw temperature) was measured after every 10 consecutive activations, until 300 transections of the porcine liver were performed. Tissue pad degradation was evaluated after 300 activations. Sealing performance was evaluated using excised porcine carotid vessels; vessel sealing speed and frequency of vessel burst pressure below 700 mmHg were determined after 300 transections of porcine liver parenchyma.
RESULTS The temperature of the H-HD1000i scalpel was approximately 10°C higher than that of the H-1100 scalpel, and gradually increased as the number of activations increased. The median passive jaw temperature of the H-HD1000i scalpel was significantly higher than that of the H-1100 scalpel (73.4°C vs 65.1°C; P < 0.001). After 300 transections of porcine liver parenchyma, less tissue pad degradation was observed with the H-1100 scalpel than with the H-HD1000i scalpel (0.08 mm vs 0.51 mm). The H-1100 scalpel demonstrated faster vessel-sealing speed (4.9 sec. vs 5.1 sec.) and less frequent vessel burst pressure < 700 mmHg (0% vs 40%) after 300 activations than the H-HD1000i scalpel; however, the difference did not reach statistical significance (P = 0.21 and P = 0.09, respectively).
CONCLUSION In an ex vivo porcine hepatectomy model, the H-1100 scalpel shows lower passive jaw temperature and maintains its sealing performance by avoiding tissue pad degradation compared to that with the H-HD1000i.

[PMID: 36105859 PMCID: PMC9464866 DOI: 10.3389/fped.2022.998106] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/19/2022] [Accepted: 08/05/2022] [Indexed: 11/15/2022] Open
Abstract
BACKGROUND AND OBJECTIVE In spite of being one of the most common surgical procedures performed in adults, laparoscopic cholecystectomy (LC) is relatively uncommon in the pediatric age group. Most surgeons prefer to dissect the cystic duct using a monopolar electrosurgical hook and occlude it with simple metal clips. Although the safety of using the ultrasonically-activated shears, e.g., harmonic scalpel for dissection of the gallbladder is confirmed in many studies, its efficacy in the closure of the cystic artery and duct in adults is still debatable. Furthermore, very few reports studied its safety in children during LC. The aim of our work is to study the safety and efficacy of ultrasonic shears in controlling the cystic duct and artery during LC in children. MATERIALS AND METHODS A prospective study was conducted from May 2017 to April 2020, where all children having symptomatic gallbladder stone disease were included in the study. HS was used as a sole instrument in gallbladder dissection as well as in controlling cystic duct and artery. No metal clips or sutures were used throughout the procedure. RESULTS A total of forty-two children having symptomatic gallstone disease were included in the study. The main indication for LC was hemolytic anemia. Their age ranged from 3 to 13 years with a mean of 8.4 ± 3.25 years. All operations were completed laparoscopically, i.e., no conversion to open surgery was needed. The mean operative time was 40 ± 10.42 min. There were no intraoperative complications apart from gall bladder perforation in two cases during dissection from the liver bed while the postoperative recovery was smooth in all patients. Patients started oral feeding after 11.30 ± 3.01 h. The mean time for discharge was 25.47 ± 7.49 h, ranging from 14 to 48 h. Postoperative ultrasound for all cases showed no evidence of minor or major bile leaks or CBD injuries. CONCLUSION This is the first report to evaluate the use of HS as a sole instrument during LC in the pediatric age group. HS is a safe and efficient instrument that can be used alone in gallbladder dissection as well as in controlling cystic duct and artery during LC in children.

Abstract
The advent of trans-oral robotic surgery (TORS) has facilitated removal of tumors previously deemed unresectable, by providing access to the deep structures of the head and neck. Despite this, the wider dissemination of TORS has been restricted due to issues with line of access, as the da Vinci robot was never designed with head and neck surgery in mind. Flexible instruments and novel energy delivery devices offer great potential in overcoming some of the existing challenges surrounding TORS. This review aimed to summarize the existing literature surrounding energy delivery in TORS and highlight areas of future innovation. MEDLINE was searched for studies relating to energy delivery in TORS in November 2019. The existing literature surrounding monopolar and bipolar electrocautery, LASER (CO2, Tm:YAG and blue LASER), Ligasure and Harmonic was reviewed. Additionally, the latest iteration of the da Vinci; the SP, and the FLEX robot were evaluated as novel methods of energy delivery in TORS. Overall, these novel energy devices and robotic systems are predicted to further improve energy delivery to the head and neck. The use of flexible LASER in particular is well substantiated in the literature. This has the potential to achieve treatment de-escalation, based on the excellent outcomes demonstrated for disease-free margins and post-operative morbidity.

Abstract
Introduction: We evaluated and compared five currently available energy-based vessel sealing devices to assess typical surgical metrics. Methods: We tested Caiman 5 (C5), Harmonic Scalpel Ace Plus (HA), Harmonic Ace +7 (HA7), LigaSure (LS), and Enseal G2 (ES) on small (2–5 mm), medium (5.1–7 mm), and large (7.1–9 mm) vessels obtained from 15 Yorkshire pigs. Vessels were randomly sealed and transected. We recorded sealing and transection time, charring and carbonization, thermal spread, and bursting pressure (BP). Specimens were sent for histopathologic evaluation of seal quality and thermal spread. Results: A total of 246 vessels were evaluated: 125 were arteries and 121 were veins. There was no difference in BPs for small size arteries. For medium arteries, C5 provided the highest BP (proximal and distal jaw), followed by HA7, ES, LS, and HA [1740, 1600, 1165, 1165, 981, and 571 mm Hg, respectively, HA<C5-D(<0.001); HA<C5-P(<0.001); HA<ES(0.002); HA<HA7(0.002); HA7<C5-P(0.026); ES<C5-P(0.026); LS<C5-P(0.001); LS<C5-D(0.014)]. For large arteries, C5 and LS provided highest BP followed by HA7, ES, and HA [1676, 530, 467, 467, and 254 mm Hg, respectively, C5<HA(<0.001); C5<HA7(0.006); C5<ES(0.006); C5<LS(0.012)]. There were no bursting pressure failures for C5, HA7, and LS up to 9 mm vessels. For medium and large size arteries, HA had bursting failure of 20% and 40%, respectively. The ES was significantly less efficient with small, medium, and large arteries with bursting failure rates of 10%, 40%, and 80%, respectively. Conclusions: In this study, C5 outperformed all other devices. However, all of the devices provide a seal that was superphysiologic in that all burst pressures were >250 mm Hg.

Abstract
Background and Objectives: The ultrasonically activated scalpel is a surgical instrument that is used in minimally invasive surgery to safely cut and seal vessels. This study reported the experimental observations of the use of a laparoscopic ultrasonic scalpel, including its safety and feasibility. in sealing vessels of different diameters in an in vivo animal model during both physiological and supraphysiological blood pressure (BP) conditions. Methods: One healthy female swine was used. We performed resections of the omentum, biopsies in different regions of the liver, and a hysterectomy. Vessels with diameters ranging from 2 to 10 mm were sealed with the ultrasonic scalpel under regular hemodynamic conditions and during pharmacologically induced arterial hypertension (BP challenge). Results: For 10 random cuts made in the omentum and during the hysterectomy, the ultrasonic scalpel was effective and fast, with no immediate or delayed bleeding. Bipolar energy, sutures, and hemoclips were not required to control bleeding. No bleeding was observed in sealed vessels up to 8 mm, even during BP challenges sustained for longer than 5 minutes. When testing vessels of 10 mm, bleeding occurred in 1 common iliac vein before 10 minutes of waiting (the point of bleeding was easily identified) and bleeding occurred in 1 of the common iliac arteries during the BP challenge. Conclusion: Our findings corroborate that the ultrasonic scalpel can safely seal arteries up to 8 mm in diameter to prevent or control bleeding during laparoscopic procedures, even when BP exceeds normal levels.

Abstract
BACKGROUND New laparoscopic devices, such as electrothermal bipolar-activated devices (LigaSure™ (LS)) or ultrasonic systems (Harmonic® scalpel (HS)), have been applied recently to bariatric surgery allowing to reduce blood loss and surgical risks. The aim of this study was to retrospectively compare intraoperative performance of HS and LS, postoperative results, and clinical outcomes in a large cohort of patients undergoing LSG. METHODS Data from 422 morbidly obese patients undergoing LSG in our Bariatric Unit at the Advanced Biomedical Sciences Department of the "Federico II" University of Naples (Italy) between January 2009 and December 2017 were retrospectively analyzed. Subjects were divided into two groups (HS and LS), and operative time, intraoperative complications, and postoperative (within 30 days from surgery) complications were compared. Bleeding from the omentum or from the staple line, use of hemostatic clips, and absorbable hemostat were recorded as intraoperative complications; hemorrhages, abscess formation, gastric leaks, fever, and mortality were considered as postoperative complications. RESULTS Statistical analysis showed no difference in terms of baseline demographics between the two cohorts. Operative time (48 ± 9 vs 49 ± 6 min, p=0.646) and the rates of intraoperative and postoperative complications did not significantly differ between groups. CONCLUSION Harmonic® and LigaSure™ are both useful tools in bariatric surgery, and these two advanced power devices are user-friendly and can facilitate surgeon work; from this point of view, the choice of the energy device should be based on the preference of the surgeon and on the hospital costs policy and availability.

Abstract
Purpose Among the various energy-based devices, ultrasonic shears are popular in thyroid surgeries. In this study, we tested the safety of Harmonic ACE and Harmonic ACE+ around the recurrent laryngeal nerve (RLN) in experimental swine models. Methods Harmonic ACE and Harmonic ACE+ were each tested in 4 piglets. Harmonic ACE and Harmonic ACE+ were activated at a 0- to 5-mm distance from the RLN. The function of the RLN was assessed using continuous electrophysiological monitoring. Results For Harmonic ACE, there was no adverse EMG event found when activated at 4- and 5-mm distances from the RLN. At a 2- to 3-mm distance, there were 4 adverse EMG events observed. In these 4 cases, adjacent tissue shrinkage occurred after 6 to 15 seconds of activation, and the RLN touched the Harmonic ACE. At a 1-mm distance, there were 2 adverse EMG events found after 25 seconds of activation. For Harmonic ACE+, there was no adverse EMG event observed when activated at 1- and 3-mm distances from the RLN. At a 0-mm distance, 2 adverse EMG events occurred after 6 to 10 seconds of activation. Conclusion The safe distance of Harmonic ACE and ACE+ was 4 and 1 mm, respectively, in the swine models. Harmonic ACE+ is safer than Harmonic ACE because it did not cause any tissue shrinkage. Surgeons need to understand the characteristics of devices for safe operation.

Abstract
Background The aim of this study was to investigate the early and late results of use of LigaSure, Harmonic Scalpel, and conventional hemorrhoidectomy in hemorrhoidectomy, to determine the least painful method, and to investigate the relationship between pain perception and personal differences in hemorrhoid bundles. Material/Methods Ninety patients undergoing hemorrhoidectomy between 2014 and 2017 were retrospectively evaluated. We investigated the duration of hospitalization and the presence of bleeding, incontinence, perianal wetness, urinary retention, stenosis, and recurrence during follow-up after surgery. Analgesic requirement was determined by Patient-Controlled Analgesia, as well as pain score by use of the Visual Analog Score and patient satisfaction by Short Form-36. We also assessed the relationship between pain and lateral thermal damage, the number of peripheral nerves, number of excised bundles, and the number of thrombosed vessels, as determined by histopathological examination. Results No differences were found among the 3 methods in the duration of hospitalization, the presence of bleeding, fecal incontinence, perianal wetness, urinal retention, anal stenosis, recurrence rate, VAS, analgesic consumption, or results of the SF-36. There was no difference in the number of bundles, thrombosed vessels, or number of nerve fibers in a bundle, but the LigaSure Hemorrhoidectomy had more lateral thermal damage (p<0.001). While there was a difference between VAS of day 1 and 7 according to the hemorrhoid bundles, there was no difference in the other parameters. Conclusions There was no difference among the 3 methods in terms of complications, postoperative pain, or patient satisfaction, and pain intensity was positively correlated with the number of excised bundles.

Abstract
Background We performed an umbrella review of systematic reviews summarizing the evidence on the Harmonic scalpel (HS) compared with conventional techniques in surgical oncology (including lymph node dissection). Methods We searched MEDLINE, EMBASE, and the Cochrane Database of Systematic Reviews from inception to end of March of 2017 for meta-analyses or systematic reviews of randomized trials comparing HS to conventional techniques in surgical oncology. We assessed the quality of included systematic reviews with AMSTAR (A MeaSurement Tool to Assess systematic Reviews) and assessed the certainty in evidence for each pooled outcome using GRADE (Grading of Recommendations Assessment, Development, and Evaluation). Results We identified ten systematic reviews on breast cancer (n = 3), gastric cancers (n = 3), oral, head, and neck cancers (n = 1), and colon cancers (n = 3). Most reviews received a higher rating using AMSTAR. For operative time, systematic reviews reported a reduction of 25 to 29 min for HS compared with conventional methods across oncology types, with the exception of breast cancer where little differences were observed (very low to moderate quality of evidence (GRADE)). For blood loss and drainage volume, the majority of reviews reported statistically significant reductions with HS, and reductions ranged from 42 to 141 mL, and from 42 to 292 mL, respectively (very low to moderate quality of evidence). Hospitalization days were reported to decrease with use of HS by 0.2 to 3.2 days; however, reductions were only statistically significant for half of the included reviews (low to moderate quality of evidence). Regarding perioperative complications, two of six reviews reported a significantly reduced risk with HS use (breast cancer surgery) (moderate to high quality evidence)). Conclusion Across surgical oncology types, the majority of included systematic reviews showed a statistically significant or numerical improvement in surgical outcomes with use of the HS compared with conventional methods. Well-designed randomized studies with large sample sizes will help to provide more precise estimates and reduce the risk of heterogeneity.

Abstract
BACKGROUND AND OBJECTIVE The Harmonic ACE+7 Shears with Advanced Hemostasis Mode (Ethicon, Somerville, NJ, USA) is an ultrasonic device designed to transect and seal vessels up to 7 mm in diameter. The device applies an algorithm that optimizes ultrasonic energy delivery combined with a longer sealing cycle. The purpose of this study was to assess the initial clinical experience with the Harmonic device by evaluating large-vessel sealing during laparoscopic colectomy in consecutive cases. METHODS This prospective, multicenter, observational series involved 40 adult patients who were to undergo elective laparoscopic colectomy where dissection and transection of the inferior mesenteric artery was indicated. The primary study endpoint was first-pass hemostasis, defined as a single activation of the Advanced Hemostasis Mode to transect and seal the inferior mesenteric artery. The use of any additional energy device or hemostatic product to establish or maintain hemostasis was noted. Patients were observed after surgery for ∼4 weeks for adverse events that were considered to be related to the study procedure or study device. Descriptive statistical analyses were performed for study endpoints. RESULTS Forty patients underwent the laparoscopic colectomy procedure. First-pass hemostasis of the inferior mesenteric artery was achieved and maintained in all 40 patients, with no required additional hemostatic measures. Exposure of the vessel was reported as skeletonized in 22 of 40 (55%) patients. Mean transection time was 21.9 ± 7.4 s. One adverse event (postoperative anemia) was considered possibly related to the study device. CONCLUSION In this initial clinical consecutive series, the device demonstrated successful transection and sealing of the large mesenteric vessels during laparoscopic colorectal surgery.
