Project description:Minimally invasive direct coronary artery bypass grafting for the left anterior descending artery is a well-established technique; however, harvesting the internal thoracic artery is challenging, particularly with endoscopic approaches. In this study, 12 patients underwent internal thoracic artery harvesting using a three-dimensional endoscope with a three-port system (one incision plus two ports). Working space was established by elevating the chest wall upward using hooks anchored at the main incision site. To enhance operability, the positions of the camera and instruments were strategically adjusted within the existing ports, obviating the need for additional access points. All patients achieved graft patency. No complications, such as internal thoracic artery injury, were observed, and no patient required conversion into median sternotomy. This approach minimizes invasiveness while maintaining effectiveness, allowing for adequate dissection of the internal thoracic artery without necessitating expansion of the existing surgical setup.

Project description:We analyzed the clinical outcomes of open radial artery harvesting (OAH) and endoscopic radial artery harvesting (EAH) undergoing coronary artery bypass grafting (CABG). We designed this meta-analysis conducted using Pubmed, Medline, the Cochrane Library, and EMBASE. Articles with comparisons of OAH and EAH undergoing CABG were included. Primary outcomes included the wound infection rate, the wound complication rate, neurological complications of the forearm, in-hospital mortality, long-term survival, and the patency rate. The results of our study included six randomized controlled trials (RCTs), two non-randomized controlled trials (NRCTs) with matching, and 10 NRCTs. In total, 2919 patients were included in 18 studies, while 1187 (40.7%) and 1732 (59.3%) patients received EAH and OAH, respectively. EAH was associated with a lower incidence of wound infection (RR = 0.29, 95% confidence interval (CI) = 0.14 to 0.60, p = 0.03), and neurological complications over the harvesting site (RR = 0.41, 95% CI = 0.27 to 0.62, p < 0.0001). There was no significant difference in 30-day mortality, long-term survival (over one year), and the graft patency rate. According to our analysis, endoscopic radial artery harvesting can improve the outcome of the harvesting site, without affecting the mortality, long-term survival, and graft patency.

Project description:BACKGROUND:Minimally invasive approach is used to repair as many defects of the abdominal wall as possible with the same approach, with the advantages implied by this way to perform surgery. Nowadays, efforts are made to create a minimally invasive approach to cope with the necessity to repair different defects of the abdominal wall at the same time. METHODS:A minimally invasive approach, with long standing endoscopic and laparoscopic principles on a well stablished inguinal hernia repair technique (Lichtenstein), is used to create a new approach to restore a unilateral inguinal hernia with the possibility to perform an adjunctive approach to solve other defects of the abdominal wall, in this case midline incisional hernia. A written consent was previously obtained, and Institutional Review Board approval was not needed. RESULTS:We performed an endoscopic repair of a right inguinal hernia, and a laparoscopic approach using the same surgical site to repair a midline incisional hernia. Patient was discharged at 36 hs post-procedure. Sixth month later the patient does not have evidence of a recurrence of either defect. CONCLUSION:This new approach has proved to be feasible, giving the advantages of a minimally invasive approach, but more experience and time are needed before getting objective and real conclusions.

Project description:BACKGROUND:Advancements in surgical robotic technology over the last two decades have enabled coronary artery bypass grafting to be performed totally endoscopically, and have the potential to significantly change clinical practice in the future. METHODS:A systematic review of studies reporting clinical outcomes of total endoscopic coronary artery bypass grafting (TECABG) was performed. RESULTS:14 appraised studies included 880 beating heart TECABGs, 360 arrested heart TECABGs, 633 one-vessel operations and 357 two-vessel operations. Patients were generally low-risk. There was a significant learning curve. The weighted means for short-term beating heart and arrested heart TECABG results respectively were: intraoperative exclusion rate of 5.7% and 1.9%, intraoperative conversion rate of 5.6% and 15.0%, all-cause mortality of 1.2% and 0.4%, stroke of 0.7% and 0.8%, myocardial infarction of 0.8% and 1.8%, new onset atrial fibrillation of 10.7% and 5.1% and post-operative reintervention rate of 2.6% and 2.3%. The overall rate of short term postoperative graft patency for beating heart and arrested heart TECABG was 98.3% and 96.4% respectively. CONCLUSIONS:Appropriate patient selection was important in minimizing the risk of intraoperative and postoperative complications. Short-term outcomes of both beating and arrested heart TECABG were acceptable, but results so far have been heterogeneous. There were fewer studies reporting intermediate to long-term outcomes, but results were encouraging, and further investigation and development of the procedure is warranted.

Project description:BackgroundTo compare the clinical outcomes, quality of saphenous vein (SV) grafts, and wound complications between endoscopic vein harvesting (EVH) technique and open vein harvesting (OVH) technique in patients with coronary artery bypass graft (CABG) surgery.MethodsWe reviewed one hundred patients with multi-vessel coronary artery disease who underwent elective CABG and agreed to preserve their SV specimens for study. Fifty patients (OVH group) underwent OVH, and the remaining (EVH group) underwent EVH. The median follow-up time was 12 months. Clinical outcomes, 1-year graft patency rates, endothelium integrity of SV grafts and wound complications were assessed.ResultsThe follow-up time was 12 [12-13] months. Recurrence of angina was observed in 5 patients, with 3 (6.1%) in EVH group and 2 (4%) in OVH group (P=0.68). The endothelium integrity of specimens before distension was similar in both the groups (EVH: 81.1%±6.11% vs. OVH: 80.8%±6.58%, P=0.83). After distension, the endothelium integrity was still similar (EVH: 70.7%±9.73%; OVH: 68.3%±9.60%; P=0.22). Grafts of 5 (11.6%) patients in EVH group were classified as occluded, and 4 (9.8%) patients in OVH group showed occlusion of SV grafts (P=1.0). After day 7, the postoperative leg pain was significantly milder in EVH group than OVH group (1.16±0.76 vs. 2.50±0.91, P<0.01).ConclusionsThese findings suggest that EVH is not associated with worse clinical outcomes or conduit quality. However, it may have advantage in wound healing.

Project description:ObjectiveThe standard approach for coronary artery bypass grafting is open surgery. Totally endoscopic coronary artery bypass has emerged as an alternative for selected patients. This meta-analysis sought to evaluate clinical outcomes with this emerging technique.MethodsA PRISMA-compliant search was performed up to December 14, 2022, in PubMed (MEDLINE), Scopus, and Cochrane. Time-to-event data were reconstructed using Kaplan-Meier curves from source literature.ResultsA total of 2,774 patients with symptomatic coronary artery disease underwent totally endoscopic coronary artery bypass in 18 eligible studies. The mean patient age was 63.2 ± 12.3 years, and 77.5% (95% confidence interval [CI]: 72.2% to 82.4%) of the included patients were males. The mean operative time was 304.2 ± 155 min, whereas the mean internal mammary artery takedown time was 38.3 ± 18.4 min. Of the patients, 4.7% (95% CI: 1.6% to 9.1%) required conversions to open surgery. The 30-day complication rate was 5.9% (95% CI: 1.2% to 13.1%), whereas late complications developed in 4.8% (95% CI: 1.9% to 8.5%) of the patients. Freedom from major adverse cardiac events was 93.4% (95% CI: 85.3% to 94.8%) and 1-year, 5-year, and 10-year survival rates were 95.2%, 83.2%, and 81.7%, respectively. Reintervention was required in 3.3% (95% CI: 2.3% to 4.4%) of the cohort within a mean follow-up of 42.5 ± 27.8 months.ConclusionsTotally endoscopic coronary artery bypass may be a safe and viable alternative for selected patients with coronary artery disease. Long-term follow-up will help define the place of robotic endoscopic treatment in the armamentarium of myocardial revascularization.

Project description:ObjectiveTo evaluate angiographic and clinical outcomes associated with open and closed dissection tunnel endoscopic vein harvesting (EVH) devices.BackgroundA previous PREVENT-IV (PRoject of Ex-vivo Vein graft ENgineering via Transfection IV) analysis reported that EVH for coronary artery bypass graft surgery was associated with worse outcomes than with traditional vein harvesting; however, outcomes by EVH device type were not available.MethodsUsing data from the PREVENT-IV trial, we compared 1549 patients from 75 surgical sites who underwent EVH with open (n = 390) or closed (n = 1159) harvest tunnel devices. Outcomes included the incidence of vein graft failure at 12 to 18 months and a composite of death, myocardial infarction, and revascularization through 5 years.ResultsAmong patients undergoing open and closed tunnel EVH, no difference in the per-patient incidence of vein graft failure (43.8% vs 47.1%; adjusted odds ratio, 0.91; 95% confidence interval, 0.53-1.55; P = 0.724) or per-graft incidence of vein graft failure (25.5% vs 25.9%; adjusted odds ratio, 0.96; 95% confidence interval, 0.59-1.55; P = 0.847) was observed. At 5 years, no difference was observed in the primary composite clinical outcome between patients who underwent open and closed system EVH (21.5% vs 23.9%; adjusted hazard ratio, 0.85; 95% confidence interval, 0.66-1.10; P = 0.221).ConclusionsNo differences in angiographic or clinical outcomes were observed among patients who underwent open versus closed tunnel endoscopic harvesting for coronary bypass surgery. These findings suggest that the risks associated with EVH that were reported in a previous PREVENT-IV analysis are not related to a specific EVH device.

Project description:Coronary artery bypass grafting is the most common cardiac surgical procedure performed worldwide and the long saphenous vein the most common conduit for this. When performed as an open vein harvest (OVH), the incision on each leg can be up to 85cm long, making it the longest incision of any routine procedure. This confers a high degree of morbidity to the procedure. Endoscopic vein harvest (EVH) methods were popularised over two decades ago, demonstrating significant benefits over OVH in terms of leg wound complications including surgical site infections. They also appeared to hasten return to usual activities and wound healing and became popular particularly in North America. Subgroup analyses of two trials designed for other purposes created a period of uncertainty between 2009-2013 while the impact of endoscopic vein harvesting on vein graft patency and major adverse cardiac events was scrutinised. Large observational studies debunked the findings of increased mortality in the short-term, allowing practitioners and governing bodies to regain some confidence in the procedure. A well designed, adequately powered, randomised controlled trial published in 2019 also definitively demonstrated that there was no increase in death, myocardial infarction or repeat revascularisation with endoscopic vein harvest. Endoscopic vein harvest is a Class IIa indication in European Association of Cardio-Thoracic Surgery (EACTS) and a Class I indication in International Society of Minimally Invasive Cardiac Surgery (ISMICS) guidelines.

Project description:BackgroundCoronary artery bypass grafting using the radial artery has, since the 1990s, gone through a revival. Observational studies have indicated better long-term patency when using radial arteries. Therefore, radial artery might be preferred especially in younger patients where long time patency is important. During the last 10 years different endoscopic techniques to harvest the radial artery have evolved. Endoscopic radial artery harvest only requires a small incision near the wrist in contrast to open harvest, which requires an incision from the elbow to the wrist. However, it is unknown whether the endoscopic technique results in fewer complications or a graft patency comparable to open harvest. When the radial artery has been harvested, there are two ways to use the radial artery as a graft. One way is sewing it onto the aorta and another is sewing it onto the mammary artery. It is unknown which technique is the superior revascularisation technique.Methods/designThe NEO Trial is a randomised clinical trial with a 2 × 2 factorial design. We plan to randomise 300 participants into four intervention groups: (1) mammario-radial endoscopic group; (2) aorto-radial endoscopic group; (3) mammario-radial open surgery group; and (4) aorto-radial open surgery group.The hand function will be assessed by a questionnaire, a clinical examination, the change in cutaneous sensibility, and the measurement of both sensory and motor nerve conduction velocity at 3 months postoperatively. All the postoperative complications will be registered, and we will evaluate muscular function, scar appearance, vascular supply to the hand, and the graft patency including the patency of the central radial artery anastomosis. A patency evaluation by multi-slice computer tomography will be done at one year postoperatively.We expect the nerve conduction studies and the standardised neurological examinations to be able to discriminate differences in hand function comparing endoscopic to open harvest of the radial artery. The trial also aims to show if there is any patency difference between mammario-radial compared to aorto-radial revascularisation techniques but this objective is exploratory.Trial registrationClinicalTrials.gov identifier: NCT01848886.Danish Ethics committee number: H-3-2012-116.Danish Data Protection Agency: 2007-58-0015/jr.n:30-0838.
