Project description:Due to its potential benefits and increased patient satisfaction minimal invasive cardiac surgery (MICS) is rapidly gaining in popularity. These procedures are not without challenges and require careful planning, pre-operative patient assessment and excellent intraoperative communication. Assessment of patient suitability for MICS by a multi-disciplinary team during pre-operative workup is desirable. MICS requires additional skills that many might not consider to be part of the standard cardiac anesthetic toolkit. Anesthetists involved in MICS need not only be highly skilled in performing transesophageal echocardiography (TEE) but need to be proficient in multimodal analgesia, including locoregional or neuroaxial techniques. MICS procedures tend to cause more postoperative pain than standard median sternotomies do, and patients need analgesic management more in keeping with thoracic operations. Ultrasound guided peripheral regional anesthesia techniques like serratus anterior block can offer an advantage over neuroaxial techniques in patients on anti-platelet therapy or anticoagulation with low molecular weight or unfractionated heparin The article reviews the salient points pertaining to pre-operative assessment and suitability, intraoperative process and postoperative management of minimally invasive cardiac procedures in the operating theatre as well as the catheterization lab. Special emphasis is given to anesthetic management and analgesia techniques.

Project description:Median sternotomy incision has shown to be a safe and efficacious approach in patients who require thoracic aortic interventions and still represents the gold-standard access. Nevertheless, over the last decade, less invasive techniques have gained wider clinical application in cardiac surgery becoming the first-choice approach to treat heart valve diseases, in experienced centers. The popularization of less invasive techniques coupled with an increased patient demand for less invasive therapies has motivated aortic surgeons to apply minimally invasive approaches to more challenging procedures, such as aortic root replacement and arch repair. However, technical demands and the paucity of available clinical data have still limited the widespread adoption of minimally invasive thoracic aortic interventions. This review aimed to assess and comment on the surgical techniques and the current evidence on mini thoracic aortic surgery.Supplementary informationThe online version contains supplementary material available at 10.1007/s12055-021-01258-2.

Project description:Minimally invasive surgery, which has been extensively used to treat gastric adenocarcinoma, is now regarded as one of the standard treatments for early gastric cancer, and its suitability for advanced gastric cancer is being investigated. The use of cutting-edge techniques for minimally invasive surgery enables surgeons to deliver various treatment options to minimize a patient's distress and to maintain oncologic safety. Ongoing multicenter prospective studies aim to validate the efficacy of these surgical techniques and to expand the indications of minimally invasive surgery for the treatment of gastric cancer. In this review, we summarize the current status and issues regarding minimally invasive surgery for the treatment of gastric cancer.

Project description:We report a case of 44-year-old female patient with congenital heart disease, ostium secundum atrial septal defect (ASD) with moderate mitral regurgitation for minimally invasive ASD repair along with mitral valve repair. Venous cannulations were performed through right internal jugular vein and right femoral vein (RFV) and arterial cannulation was accomplished through right femoral artery. Intraoperative transesophageal echocardiography (TEE) could not visualize venous cannula through RFV. However, cardiopulmonary bypass (CPB) was initiated and surgery was proceeded. During surgery, patients abdomen became tense and distened, ontable ultrasound examination of abdomen was done after completion of the surgery to rule out hemoperitoneum but was inconclusive, patient was evaluated further under fluoroscopy in cathlab and found to have interrupted inferior vena cava. Postoperative course of the patient was uneventful. We discuss the importance of preoperative evaluation and the role of TEE in placement of cannulas during minimally invasive cardiac surgery.

Project description:BackgroundThere is no uniformity on the safety profile of ultra-fast-track cardiac anesthesia (UFTCA), and there is a lack of research on the postoperative lung function status of patients with UFTCA. This retrospective study was to examine the benefits of UFTCA on the postoperative recovery and pulmonary function of patients undergoing minimally invasive cardiac surgery (MICS).MethodsThis retrospective study was performed on patients who underwent MICS at Zhejiang Provincial People's Hospital between January 2022 and July 2023. Patients were retrospectively segregated into two groups: UFTCA group and conventional general anesthesia (CGA group). Primary endpoints encompassed differences in the duration of postoperative intensive care unit (ICU) stay and overall hospital stay. Secondary observations included in-hospital mortality rate, 3-month post-discharge survival rate, oxygenation indexes of preoperative (T0), immediately after extubation (T1), 6 hours after extubation (T2), and 12 hours after extubation (T3), use of high-flow nasal cannula oxygen therapy in the ICU, postoperative total chest drainage volume, and the rate of complications. Group comparisons were performed using grouped t-tests and repeated measures analysis of variance (ANOVA).ResultsThe UFTCA group (n=327) demonstrated shorter ICU and hospital stays when compared with the CGA group (n=216) (P=0.001). At the immediately after extubation, the UFTCA group exhibited a decrease in oxygenation index [arterial oxygen partial pressure (PaO2)/fraction of inspired oxygen (FiO2)] accompanied by elevated alveolar-arterial oxygen tension difference [P(A-a)O2] and respiratory index [P(A-a)O2/PaO2] values compared to the CGA group (P=0.001). However, by 12 hours after extubation, the UFTCA group manifested an improved PaO2/FiO2 and diminished P(A-a)O2/PaO2 values compared to the CGA group. The UFTCA group required high-flow oxygen therapy after extubation with greater frequency than the CGA group (P=0.001). However, neither the UFTCA nor CGA group had patients who needed reintubation (P>0.05). No significant differences were observed in postoperative atelectasis and pulmonary edema rates between the groups (P>0.05), the UFTCA group recorded a diminished total chest drainage volume postoperatively (P=0.001). Incidence of postoperative nausea and vomiting (PONV) was heightened in the UFTCA group (P=0.01), while the incidence of delirium was less frequent when compared with the CGA group (P=0.001).ConclusionsUFTCA demonstrates potential benefits in minimizing ICU and postoperative hospital stay in patients undergoing MICS. This approach also contributes to a reduction in postoperative chest drainage volume and a decreased likelihood of postoperative delirium. Despite the initial decline in lung oxygenation immediately following early post-extubation, subsequent lung function proves to be superior, with no differences in postoperative atelectasis or pulmonary edema rates. However, the implementation of UFTCA requires additional strategies to prevent the occurrence of PONV.

Project description:BackgroundPrimary cardiac lymphoma (PCL) is extremely rare and progresses rapidly. The treatment of PCL has not yet been established. Unlike lymphoma that arises from other organs, PCL causes cardiovascular events. We report the complete remission (CR) of PCL after tumor resection using minimally invasive cardiac surgery (MICS) and chemotherapy.Case presentationThe patient was a 79-year-old man who visited our hospital with chief complaints of weight loss and leg edema. A 40 × 30 mm mobile pedunculated tumor continuous with the right ventricular heart muscle was present in the right atrium upon echocardiography and extended cardiac surgery was difficult to perform. Tumor embolism-induced sudden death was prevented and a pathological diagnosis was obtained by making a 4-cm skin incision, and tumor resection with MICS was performed through a right fourth intercostal thoracotomy with a cardiopulmonary system. The histopathological diagnosis was diffuse large B cell malignant lymphoma. Eight cycles of postoperative rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) therapy were performed. Three years after surgery, the tumor was not visible on imaging and CR was maintained.ConclusionsThis case highlights that tumor resection using MICS is effective for avoiding the risk of sudden death. This technique was useful for the diagnosis and treatment of a malignant cardiac tumor in an elderly patient that required a difficult extended cardiac surgery.

Project description:The aim of this study is to review the literature and report the various minimally invasive methods used to treat gastric cancer in the UK and compare it with worldwide practice. Published randomised studies, non-randomised studies and case series reporting the use of minimal invasive approach to treat gastric cancer were retrieved from the search of standard medical electronic databases and their outcomes were highlighted suggesting their effectiveness. Several randomised, controlled trials and meta-analyses have proven the clinical and oncological safety of the laparoscopic gastrectomy for gastric cancer. Similarly, robot-assisted gastrectomy, EMR (endoscopic mucosal resection) and ESD (endoscopic sub-mucosal dissection) have also been proven feasible and safe to treat gastric cancer of various stages in prospective and retrospective comparative studies. However, UK based studies on minimally invasive surgery to treat gastric cancer is scarce and the paucity of trials led to uncertain outcomes. Laparoscopic gastrectomy, robot-assisted gastrectomy, EMR and ESD are feasible procedures in terms of clinical and oncological safety but mainly being practiced in Asian countries with high prevalence of stomach cancer. The UK based practice is still small and limited but the introduction of MIGOCS and STOMACH trial might help to widen the application of this technique.
