Turial S, Schwind M, Nyiredi A. Evaluation of the Appropriate LigaSure™ Device to Transect the Appendix-A Comparison between 5 mm and 10 mm Laparoscopic Devices in an Ex Vivo Trial. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:medicina59050927. [PMID: 37241159 DOI: 10.3390/medicina59050927] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/06/2023] [Revised: 04/03/2023] [Accepted: 05/05/2023] [Indexed: 05/28/2023]
Abstract
Background and Objectives: A topic of greatinterest in the surgical field comprises cost and time reduction operative techniques with high efficiency rates. Thus, the aim of this paper is to evaluate whether a transection of the appendix using only a laparoscopic LigaSure™ device is feasible and, if so, which size of the laparoscopic device is optimal. Materials and Methods: Appendectomy specimens were sealed and cut using LigaSureTM V (5 mm) and LigaSure AtlasTM (10 mm) devices ex vivo. Analysis criteria included handling, resistance to bursting pressure of the appendicular stump (adequacy), eligibility, durability and airtightness. Results: Twenty sealed areas were measured. While the 5 mm instrument was not able to transect the appendix in one attempt in any of the cases, the 10 mm device could be applied successfully without any handling difficulties. The adequacy of the sealed area was rated as complete and dry in all 10 cases using the 10 mm device and as oozing in 8 of the cases using the 5 mm device. There was no leakage in terms of air and liquid tightness using the 10 mm device, in contrast to six sealed segments with air and liquid leakage when using the 5 mm device. The resistance to bursting pressure was on average 285 mmHg and 60.5 mmHg with the 10 mm and 5 mm devices, respectively. The durability and eligibility of the 10 mm device were rated as very sufficient in 9 of 10 cases (1 perforation) in contrast to the 5 mm device, where the sealing in 9 of 10 cases was not sufficient (9 perforations). Conclusions: Using the 10 mm laparoscopic LigaSure™ device for the transection of the appendix seems to be feasible, safe and resistant to 300 mmHg bursting pressure. The 5 mm LigaSure™ instrument is inadequate to seal the appendix in humans.

Energy Devices for Clipless-Sutureless Laparoscopic Appendectomy: A Systematic Review and Meta-Analysis on Utility and Safety. MEDICINA (KAUNAS, LITHUANIA) 2022; 58:medicina58111535. [PMID: 36363491 PMCID: PMC9694935 DOI: 10.3390/medicina58111535] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/14/2022] [Revised: 10/23/2022] [Accepted: 10/25/2022] [Indexed: 11/06/2022]
Abstract
Background and Objectives: While laparoscopic appendectomy is standardized, techniques for appendiceal stump closure and mesoappendix division remain variable. Novel vessel sealing techniques are increasingly utilized ubiquitously. We sought to systematically summarize all relevant data and to define the current evidence on the safety and utility of energy devices for clipless−sutureless laparoscopic appendectomy in this systematic review and meta-analysis. Materials and Methods: This review was conducted following the PRISMA guidelines. PubMed, Embase, Scopus, and Web of Science were systematically searched. Inclusion criteria included studies with laparoscopic appendectomy for appendicitis. The intervention included patients undergoing division of mesoappendix and/or securing of the appendicular base using diathermy (Monopolar or Bipolar or LigaSure Sealing Device) or Harmonic Scalpel (Group A) compared to patients undergoing division of mesoappendix and/or securing of the appendicular base using endoclip or Hem-o-lok or ligature (Group B). The methodological quality of the included studies was assessed using the Downs and Black scale. The outcomes of surgical site infection (SSI) or intra-abdominal collection, postoperative ileus, average operative duration, and length of hospital stay (LHS) were compared. Results: Six comparative studies were included; three were retrospective, two were prospective, and one was ambispective. Meta-analysis revealed a shorter operative duration in Group A with respect to appendicular base ligation (MD −12.34, 95% CI −16.57 to −8.11, p < 0.00001) and mesoappendix division (MD −8.06, 95% CI −14.03 to −2.09, p = 0.008). The pooled risk ratios showed no difference in SSI between groups. Additionally, no difference was observed in LHS. The risk of postoperative ileus was higher in group B regarding mesoappendix division (RR 0.56, 95% CI 0.34 to 0.93, p = 0.02), but no difference was found concerning appendicular base ligation. The included studies showed a moderate-to-high risk of bias. Conclusions: Clipless−sutureless laparoscopic appendectomy is safe and fast. Postoperative ileus seems less common with energy devices for mesoappendix division. However, the studies included have a moderate-to-high risk of bias. Further studies addressing the individual devices with surgeons of similar levels are needed.

Detection of the Lateral Thermal Spread during Bipolar Vessel Sealing in an Ex Vivo Model-Preliminary Results. Diagnostics (Basel) 2022; 12:diagnostics12051217. [PMID: 35626371 PMCID: PMC9141216 DOI: 10.3390/diagnostics12051217] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2022] [Revised: 04/27/2022] [Accepted: 04/28/2022] [Indexed: 02/01/2023] Open
Abstract
Background: As an unwanted side effect, lateral thermal expansion in bipolar tissue sealing may lead to collateral tissue damage. Materials and Methods: Our investigations were carried out on an ex vivo model of porcine carotid arteries. Lateral thermal expansion was measured and a calculated index, based on thermographic recording and histologic examination, was designed to describe the risk of tissue damage. Results: For instrument 1, the mean extent of the critical zone > 50 °C was 2315 ± 509.2 µm above and 1700 ± 331.3 µm below the branches. The width of the necrosis zone was 412.5 ± 79.0 µm above and 426.7 ± 100.7µm below the branches. For instrument 2, the mean extent of the zone > 50 °C was 2032 ± 592.4 µm above and 1182 ± 386.9 µm below the branches. The width of the necrosis zone was 642.6 ± 158.2 µm above and 645.3 ± 111.9 µm below the branches. Our risk index indicated a low risk of damage for instrument 1 and a moderate to high risk for instrument 2. Conclusion: Thermography is a suitable method to estimate lateral heat propagation, and a validated risk index may lead to improved surgical handling.

Abstract
PURPOSE To study the trends, techniques, outcomes and improvisations of liver resections over the study period. METHODS We analysed prospectively maintained database of patients undergoing liver resections for oncological indications at Tata Memorial Centre, Mumbai, India from June 2010 to October 2016. RESULTS Five hundred sixteen patients were operated with median age of 55 years and male to female ratio of 1.6:1. Most commonly operated neoplasms were hepatocellular carcinoma (N = 166), cholangiocarcinoma (N = 72) and metastases from colorectal cancer (N = 129). We performed 219 major hepatic resections (≥3 segments) with overall morbidity of 22.9% (N = 118) and mortality of 4.0% (N = 21). Complex hepatectomies were performed in 78 patients. In order to study the time trends, data was divided into pre-liver clinic era and post liver clinic era. Trend analysis showed improvements in complication grade, hospital stay, blood loss, and overall survival status in post liver clinic era. Liver transection in all our patients was carried out without Pringle manoeuvre under normotensive anaesthesia, only 0.7% of our patients had significant transaminitis beyond POD 5. CONCLUSION A dedicated multidisciplinary treatment approach along with standardization of liver resections culminates into optimal treatment outcomes.

[PMID: 30719344 PMCID: PMC6335858 DOI: 10.1155/2019/3402137] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/23/2018] [Revised: 11/26/2018] [Accepted: 12/09/2018] [Indexed: 02/06/2023] Open
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
Harmonic scalpel and LigaSure vessel sealing systems have been suggested as options for saving surgical time and reducing postoperative complications. The aim of the present meta-analysis was to compare surgical time, postoperative complications and other parameters between them in for the open thyroidectomy procedure. Studies were retrieved from MEDLINE, Cochrane Library, EMBASE and ISI Web of Science until December 2015. All the randomized controlled trials (RCTs) comparing Harmonic scalpel and LigaSure during open thyroidectomy were selected. Following data extraction, statistical analyses were performed. Among the 24 studies that were evaluated for eligibility, 7 RCTs with 981 patients were included. The Harmonic scalpel significantly reduced surgical time compared with LigaSure techniques (8.79 min; 95% confidence interval, -15.91 to -1.67; P=0.02). However, no significant difference was observed for the intraoperative blood loss, postoperative blood loss, duration of hospital stay, thyroid weight and serum calcium level postoperatively in either group. The present meta-analysis indicated superiority of Harmonic Scalpel only in terms of surgical time compared with LigaSure hemostasis techniques in open thyroid surgery.

Efficacy of a half-grip technique using a fine tip LigaSure™, Dolphin Tip Sealer/Divider, on liver dissection in swine model. BMC Res Notes 2015; 8:362. [PMID: 26289073 PMCID: PMC4543461 DOI: 10.1186/s13104-015-1316-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2014] [Accepted: 08/03/2015] [Indexed: 11/21/2022] Open
Abstract
BACKGROUND Recently, a lot of energy devices in the surgical field, especially in the liver surgery, have been developed, and a fine tip LigaSure™, Dolphin Tip Sealer/Divider (DT-SD) also has been used frequently to dissect liver parenchyma as well as ultrasonically activated device (USAD). However, the utility of this instrument for liver dissection (LD) is still unknown. Moreover, to reduce bleeding during LD, a half-grip technique (HGT) was contrived. We herein report an experimental study in swine model to evaluate the feasibility and effectiveness of HGT using DT-SD for LD. METHODS The swine model experiment was carried out under general anesthesia by veterinarians. LD was performed repeatedly by DT-SD with the HGT (Group A, n = 6), or the conventional clamp-crush technique (CCT) (Group B, n = 6), and by variable mode USAD (Group C, n = 6). The dissection length and depth (cm) as well as bleeding volume (g) were measured carefully, and the dissection area (cm(2)) and speed (cm(2)/min) were calculated precisely. Histological examinations of the dissection surfaces were also executed. Mann-Whitney's U test was used for Statistical analyses with variance at a significance level of 0.05. RESULTS Among the three groups, the three averages of dissection lengths were unexpectedly equalized to 8.3 cm. The dissection area (cm(2)) was 9.9 ± 5.1 in Group A, 9.8 ± 4.7 in Group B, and 9.9 ± 4.5 in Group C. The mean blood loss during LD was 10.6 ± 14.8 g in Group A, 41.4 ± 39.2 g in Group B, and 34.3 ± 39.2 g in Group C. For Group A, the bleeding rate was the least, 0.9 ± 1.0 g/cm(2), and the average depth of coagulation was the thickest, 1.47 ± 0.29 mm, among the three groups (p < 0.05). The dissection speed in Group A (1.3 ± 0.3 cm(2)/min) was slower, than that in Group C (p < 0.05). CONCLUSIONS This report indicates firstly that the HGT using DT-SD bring the least blood loss when compared with CCT or USAD. Although the HGT is feasible and useful for LD, to popularize the HGT, further clinical studies will be needed.

Abstract
The continuing evolution of technique and devices used in laparoscopic liver resection (LLR) has allowed successful application of this minimally invasive surgery for the treatment of liver disease. However, the type of instruments by energy sources and technique used vary among each institution. We reviewed the literature to seek the best technique for parenchymal transection, which was proposed as one of the important clinical question in the 2nd International Consensus Conference on LLR held on October 2014. While publications have described transection techniques used in LLR from 1991 to June 2014, it is difficult to specify the best technique and device for laparoscopic hepatic parenchymal transection, owing to a lack of randomized trials with only a small number of comparative studies. However, it is clear that instruments should be used in combination with others based on their functions and the depth of liver resection. Most authors have reported using staplers to secure and divide major vessels. Preparation for prevention of unexpected hemorrhaging particularly in liver cirrhosis, the Pringle's maneuver and prompt technique for hemostasis should be performed. We conclude that hepatobiliary surgeons should select techniques based on their familiarity with a concrete understanding of instruments and individualize to the procedure of LLR.

Abstract
Transection methods and hemostasis achievement have an impact on blood loss, and consequently on outcome and survival. However, no consensus exists on parenchymal transection or hemostasis techniques in laparoscopic liver resection (LLR). The aim of this review is to clarify the role of energy devices (ED) in LLR. ED is a generator of mechanic or electric energy transfer to an operating tool, used for transection, sealing or both. Searches were performed in PubMed, PubMed Central, Cochrane, Embase, Google Scholar in human or animal experimental models. Each study quality was graded following the GRADE system. From 1996 to 2014, 30 studies were found: five comparative, one prospective, two case-control, and 16 case series and some case reports, with level of evidence ranging from Moderate to Very Low. Since 2012, the Research and Development of new tools raised quicker than clinical studies could follow. The two main techniques emerged are blind transection versus sharp dissection: due to the low quality and heterogeneity of the studies, no firm conclusion can be drawn, but meticulous dissection of vessels usually never leads to vascular damage. As a matter of fact, ED, though efficient and reliable, cannot replace the basic skills of hepatic surgery: sharp dissection, vascular control and elective sealing.

The aim of the present systematic review was to compare operation time and postoperative morbidity for ultrasonic and electrothermal bipolar-activated devices with conventional hemostasis techniques and with each other in open thyroidectomy. METHODS A systematic literature search (MEDLINE, Cochrane Library, EMBASE and ISI Web of Science) was performed to identify randomised controlled trials (RCTs) comparing conventional hemostasis techniques, ultrasonic devices (Harmonic® scalpel) and/or electrothermal bipolar-activated vessel sealing systems (Ligasure®) during open thyroidectomy. For the primary endpoint (operation time), a network meta-analysis with Bayesian random effects model was performed. Pairwise meta-analyses with random effects were calculated for primary and secondary endpoints. RESULTS One hundred sixteen publications were evaluated for eligibility; 35 RCTs (4,061 patients) were included. There was considerable methodological and clinical heterogeneity of included trials. The Harmonic scalpel significantly reduced operation time compared with conventional techniques (22.26 min, 22.7 min in the inconsistency model). The use of Ligasure significantly reduced operation time in total thyroidectomy (13.84 min in the consistency model, 12.18 min in the inconsistency model). In direct comparison, operations with the Harmonic scalpel were faster than with Ligasure (8.42 min in the consistency model, 2.45 min in the inconsistency model). The rates of recurrent nerve palsy and postoperative hypocalcaemia did not significantly differ in the intervention groups. CONCLUSIONS This meta-analysis shows superiority of ultrasonic devices in terms of operation time compared with conventional hemostasis techniques in thyroid surgery, with no detriment to safety outcomes.

Abstract
BACKGROUND Although the LigaSure device is widely used, its use in liver transplantation, where compounding factors of portal hypertension, coagulopathy, and thrombocytopenia exist, is poorly described. METHODS From October 1, 2011, to December 31, 2011, 6 patients underwent liver transplantation with recipient hepatectomy utilizing the LigaSure device. Outcomes using the device were compared with 6 contemporaneous patients in whom the device was not used. RESULTS Patient demographics, preoperative laboratory values, and Model for End-Stage Liver Disease scores were not different. Recipient hepatectomy was performed, on average, 43 minutes faster using the LigaSure device (P = .02). Although total operative time and intraoperative blood product usage were lower when the LigaSure was used, these differences did not attain statistical significance. Duration of stay and recipient readmission rates were similar. CONCLUSIONS LigaSure vessel sealing is an efficient method for recipient hepatectomy in liver transplantation. Vessel sealing of caval, portal, and other structures can be safely performed in the setting of end-stage liver disease.

Abstract
Liver resections are demanding operations which can have life threatening complications although they are performed by experienced liver surgeons. The parameter “Blood Loss” has a central role in liver surgery, and different strategies to minimize it are a key to improve results. Moreover, recently, new technologies are applied in the field of liver surgery, having one goal: safer and easier liver operations. The aim of this paper is to review the different principal solutions to the problem of blood loss in hepatic surgery, focusing on technical aspects of new devices.

Abstract
A bipolar electrosurgical device was found to provide safe division and effective closure of the cystic duct during laparoscopic cholecystectomy. Background: Cystic duct leakage after cholecystectomy is not uncommon and is a potentially serious complication. The aim of this study was to assess a bipolar sealing system (LigaSure®) for closure of the cystic duct. Methods: The records from consecutive laparoscopic cholecystectomies performed in 2 hospitals with closure of the cystic duct with LigaSure after informed consent were recorded and complications and morbidity registered. The records were compared with those of patients undergoing laparoscopic cholecystectomy with closure of the cystic duct with clips during the same period. Results: During the study period, 218 laparoscopic cholecystectomies were performed; 102 of these were performed with the LigaSure. One patient was excluded due to violation of the protocol. We experienced no cases of cystic duct leakage, but in one patient, bile leakage from the gallbladder bed was observed probably due to a small aberrant duct. Conclusion: The LigaSure system was safe and effective for closure and division of the cystic duct in laparoscopic cholecystectomy.

Abstract
Great advances have occurred in the field of laparoscopic hepatic surgery. It is now clear that in experienced hands, the laparoscopic method of liver resection is as safe as an open procedure. The key phrase in this last sentence is "in experienced hands". The new devices that are available might make an inexperienced hepatic surgeon, well-trained in laparoscopic surgery, embark on hepatic resection without thorough knowledge of hepatic anatomy. The converse may also be true. As no criteria for credentialing of laparoscopic hepatic surgeons exist, the decision as to who is sufficiently trained to perform these procedures is left to individual hospital credentialing boards. While a certification procedure defined by leaders in this field and supported by surgical societies would be welcomed, the ability to achieve and enforce these guidelines appear to be more of a challenge. In addition, while most comparison studies in this area conclude by suggesting that a randomized, clinical trial would be needed to definitively arrive at an answer regarding the benefits of minimally invasive liver surgery compared with open surgery, it would likely be extremely difficult to accrue patients, given the data presented in articles regarding the success of laparoscopic hepatic resections. The authors conclude that an internationalregistry of all laparoscopic cases should b e established to insure patient safety and a mechanism for self-monitoring.
