BMC Surg 2024; 24:212. [PMID: 39030560 PMCID: PMC11264468 DOI: 10.1186/s12893-024-02497-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2024] [Accepted: 07/01/2024] [Indexed: 07/21/2024] Open
Abstract
BACKGROUND The ultrasonic scalpel is widely used during surgery. It is safe and effective to close the pulmonary artery branch vessels of 7 mm or below with an ultrasonic energy device as reported. However, there have been no multicenter randomized clinical trial to assess the safety and effectiveness of using ultrasonic scalpel to coagulate 5-7 mm blood vessels in thoracic surgery. METHODS This is a prospective, multicenter, randomized, parallel controlled, non-inferiority clinical trial. A total of 144 eligible patients planning to undergo lung or esophageal surgery will be randomly allocated to the experimental group and the control group. The investigational product (Disposable Ultrasonic Shears manufactured by Reach Surgical, Inc.) and the control product (Harmonic Ace + 7, 5 mm Diameter Shears with Advanced Hemostasis) will be used in each group. The primary endpoint is the success rate of coagulating target blood vessels during surgery. Secondary endpoints include postoperative rebleeding, intraoperative bleeding volume, drainage volume, surgical duration, etc. Postoperative follow-up before and after discharge will be performed. DISCUSSION This clinical trial aims to evaluate the safety and effectiveness of using the investigational product (Disposable Ultrasonic Shears manufactured by Reach Surgical, Inc.) and that of the control product (Harmonic Ace + 7, 5 mm Diameter Shears with Advanced Hemostasis) to coagulate 5-7 mm blood vessels in thoracic surgery. TRIAL REGISTRATION ClinicalTrials.gov: NCT06002737. The trial was prospectively registered on 16 August 2023, https://www. CLINICALTRIALS gov/study/NCT06002737 .

Clinical and biological effects of different energetic surgical devices currently used for mini-invasive anatomical lung resections for the treatment of NSCLC: a prospective interventional study. Surg Endosc 2024:10.1007/s00464-024-11014-3. [PMID: 38987484 DOI: 10.1007/s00464-024-11014-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2024] [Accepted: 06/30/2024] [Indexed: 07/12/2024]
Abstract
BACKGROUND This study aims to compare three commonly used energy devices for dissection during Video-Assisted Thoracoscopic Surgery (VATS) lobectomy: monopolar hook, advanced bipolar, and ultrasonic device, in terms of duration of the surgical procedure and clinical intra- and post-operative outcomes. MATERIALS AND METHODS In this prospective single-center study, 75 patients undergoing VATS lobectomy for non-small cell lung cancer between January 2022 and May 2023 were enrolled and divided into 3 groups based on the device used during the surgical procedure (Group 1: Ultrasonic Device, Group 2: Advanced Bipolar, Group 3: Monopolar Hook). The duration of the surgical procedure, daily pleural fluid production, post-operative pain, length of hospital stay, and occurrence of post-operative complications were compared for each group. In a subgroup of 20 patients (10 from Group 1 and 10 from Group 3), concentrations of inflammatory cytokines in pleural fluid at 3 h and 48 h post-surgery were analyzed. RESULTS Pleural fluid production on the first and second post-operative days was significantly lower in patients treated with the Ultrasonic device compared to the other two groups (p < 0.001). The duration of the surgical procedure was significantly shorter when using the Ultrasonic device (p < 0.001). There were no significant differences in length of hospital stay (p = 0.975), pain on the first and second post-operative days (p = 0.147 and p = 0.755, respectively), and blood hemoglobin levels on the first post-operative day (p = 0.709) and at discharge (p = 0.795). No differences were observed in terms of post-operative complications, although the incidence of post-operative cardiac arrhythmias was borderline significant (p = 0.096), with no cases of arrhythmias recorded in Group 1. IL-10 levels in pleural fluid of patients in Group 3 peaked at 3 h post-surgery, with a significant reduction at 48 h (p = 0.459). DISCUSSION The use of the ultrasonic device during VATS lobectomy may reduce pleural fluid production and shorten the duration of the surgical procedure compared to using a monopolar hook or advanced bipolar device. The choice of energy device may influence the local inflammatory response, although further studies are needed to confirm these results.

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: 2] [Impact Index Per Article: 0.7] [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.

Interact Cardiovasc Thorac Surg 2021; 31:847-852. [PMID: 33150403 DOI: 10.1093/icvts/ivaa192] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2020] [Revised: 07/26/2020] [Accepted: 08/06/2020] [Indexed: 12/13/2022] Open
Abstract
OBJECTIVES Energy vessel-sealing devices are being increasingly utilized to seal pulmonary artery (PA) branches during lobectomy. Heat from these devices can potentially injure surrounding tissues. We evaluated heat production from devices in a live animal model. METHODS PA branches were sealed in pigs with 4 energy vessel-sealing devices: 2 ultrasonic (US), 1 advanced bipolar or 1 mixed US and bipolar (mixed) device. Thermocouples were implanted in tissue surrounding the PA branch being sealed to measure tissue temperature. A thermal camera measured the sealing site and the temperatures of the instruments. Pathological analysis was performed on PA stumps to identify thermal damage. RESULTS A total of 37 PA branches were sealed in 4 pigs. Maximum tissue heat measured by the thermocouples for the 2 US, advanced bipolar and mixed devices was 42, 39, 42 and 46°C, respectively. The mean tissue temperatures at the site of the sealing measured with the thermal camera were 78, 75, 70 and 82°C (P = 0.834) and the mean instrument blade temperatures were 224, 195, 83 and 170°C (P = 0.000005) for the 2 US, advanced bipolar and mixed devices, respectively. The mean diameter of the region with tissue reaching 60°C or more measured with the thermal camera was between 4 and 6 mm for the 4 devices (P = 0.941). On pathological analysis, PA stumps had either thermal damage on the adventitia and external media (26/37) or transmural damage (11/37) at 1 mm from sealed site. CONCLUSIONS A 3-mm safety margin between the instrument blades and vital structures is recommended. Instrument blades can reach high temperatures that may cause tissue damage.

Abstract
Background This study aims to compare safety and impact of monopolar electrocautery and ultrasonic dissector (Harmonic ACE Plus®) on postoperative short-term outcomes after video-assisted thoracoscopic (VATS) lobectomy and lymphadenectomy for lung cancer. Methods We analyzed the prospectively collected data of 140 consecutive patients [59% male; median age: 71(IQR:62–76) years] undergoing VATS lobectomy and lymphadenectomy in our institution between October 2016 and November 2019. Patients were divided in two groups based on device used: monopolar electric hook in 79 cases (Group A); ultrasonic dissector in 61(Group B). Energy instrument-related intraoperative accidents, hemothorax/chylothorax incidence, total pleural effusion volume at 48 postoperative hours and chest tube duration were compared between groups. Multivariable analysis was performed to test energy device as possible independent risk factor either for increased pleural effusion volume or for prolonged chest tube duration. Results No intraoperative accidents due to energy device occurred. No hemothorax was recorded. Postoperative chylothorax incidence was slightly higher in Group A (2.5% vs 0%; p-value = 0.21). Total pleural effusion volume at 48 h was significantly higher in Group B: 400 (285–500) vs 255 (150–459) ml (p-value = 0.005). Chest tube duration was similar in the two groups: 5 (3–9) vs 5 (3–8) days (p-value = 0.77). At multivariable analysis the energy device used was not associated with increased pleural effusion volume (p-value = 0.43) nor with prolonged chest tube duration (p-value = 0.28). Conclusions Monopolar electrocautery and Harmonic ACE Plus® were safe and had a similar impact on short-term outcomes after VATS lobectomy and lymphadenectomy, suggesting that energy devices choice could be left to surgeon’s preference.

Abstract
OBJECTIVES The study objectives were to evaluate the immediate, short-, and medium-term efficacy and safety of pulmonary artery branch sealing using an ultrasonic vessel-sealing device in minimally invasive anatomic lung resection. METHODS This study consists of a prospective, phase 2, multicenter, international clinical trial (clinicaltrials.gov: NCT02719717) that enrolled patients planned for video-assisted thoracoscopic surgery/robotic anatomic lung resection in 7 centers (United States, Canada, United Kingdom). Pulmonary artery branches of 7 mm or less were sealed and divided with an ultrasonic energy vessel-sealing device. The remainder of the lobectomy was performed according to surgeon preference. Intraoperative, in-hospital, and 30-day postoperative bleeding and complications were prospectively recorded. RESULTS A total of 150 patients with a minimum of 1 pulmonary artery branch sealed with an ultrasonic vessel-sealing device were prospectively enrolled in the trial. Resections included 139 lobectomies and 11 segmentectomies. A total of 424 pulmonary artery branches were divided: 239 with the ultrasonic vessel-sealing device, 181 with endostaplers, and 4 with endoscopic clips. The mean and median pulmonary artery diameters were 4.7 mm/5.0 mm, 10.3 mm/10.0 mm, and 6.5 mm/6.5 mm for each method, respectively. Three of the pulmonary artery branches divided with the ultrasonic vessel-sealing device (1.3%) and 4 pulmonary artery branches divided with endostaplers (2.2%) bled intraoperatively. Among the patients with seal failures, 1 patient required conversion to thoracotomy. There was no postoperative bleeding from divided pulmonary artery branches with either sealing method. There was no mortality at 30 days. CONCLUSIONS Pulmonary artery branch sealing with ultrasonic energy during video-assisted thoracoscopic surgery lobectomy is safe for vessels 7 mm or less. The use of an ultrasonic device is a reasonable sealing method for pulmonary artery branches 7 mm or less.
