AbstractMedian 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.

Cardiac surgery in patients already implanted with subcutaneous implantable cardioverter defibrillators (S-ICD) represents a challenge. Although a few reports described successful surgical procedures in these patients, a traditional approach with median sternotomy might potentially cause S-ICD malfunctioning. Minimally invasive techniques (e.g. left anterior thoracotomy) should be considered the first choice in order to preserve the integrity of the S-ICD system in suitable patients. Herein, we provide the first report of a patient implanted with S-ICD due to post-ischemic left ventricular dysfunction who underwent successful minimally invasive direct coronary artery bypass (MIDCAB).

Intradural, extramedullary schwannomas have long been treated with open midline incision, laminectomy, and dural opening to expose and resect the lesion. While this technique is well established, today new surgical techniques can be utilized to perform the same procedure while minimizing pain, size of incision, and trauma to adjacent tissues. In cases of intradural surgery, minimally invasive surgery limits the degree of soft tissue disruption. As a result, there is significant decreased dead space within the surgical cavity that may decrease the rate of CSF leak complications. Minimally invasive techniques have continuously improved over the years and have reached a point where they can be used for intradural surgeries. In this case presentation, we demonstrate a minimally invasive approach to the lumbar spine with resection of an intradural schwannoma. Surgical techniques and the nuances of the minimally invasive approach to intradural tumors compared to the standard open procedure will be discussed.

Introduction. Harold Hirschsprung, a physician at Queen Louise Children’s Hospital of Copenhagen, first described the disease that now bears his name, at the Pediatric Congress of Berlin in 1886. Since then there have been countless debates on the optimal surgical approach. This paper aims both to recap the main classical surgical techniques: Swenson, Duhamel and Soave, but the main focus is on minimally invasive techniques. Surgical techniques. In the last 25 years, the treatment for Hirschsprung disease has progressed. If classically the preferred treatment was in 2-3 stages, now the definitive intervention is per primam in most cases, thus avoiding the morbidity associated with stomas. In 1995, Georgeson describes the minimally invasive approach using laparoscopy, and then in 1998, De la Torre et al, describes the first transanal endorectal pull-through (TERPT), unattended laparoscopically. Discussions. The initial discussions were linked to comparing processes in a single stage with ones in 2 or 3 stages, finding similar results, it is now a question of comparing open techniques with minimally invasive and even minimally invasive techniques with each other, endeavoring to establish whether laparoscopically assisted approach is needed or if the transanal one is enough. Conclusion. Usually shorter forms of Hirschsprung disease are treated strictly using the transanal technique, for the forms involving the left and transverse colon laparoscopically assisted transanal pull-through is used, while for the ascending colon and for the total aganglionosis the laparoscopically assisted Duhamel procedure is preferred.

Minimally invasive cardiac surgery (MICS) has a number of proven advantages compared to median sternotomy. Safe cannulation and perfusion are some of the main components of the success of MICS. The aim. To present our perfusion strategy and describe the methods of cannulation, technical features, contraindications and potential complications. Materials and methods. We examined the results of 1088 adult patients who underwent primary cardiac surgery in our hospital (coronary artery bypass grafting, valve surgery, aortic surgery, left ventricle repair, congenital cardiac surgery and combined procedures) from July 2017 to May 2021. Of these, 851 patients were qualified for MICS. To select a safe cannulation strategy, we performed contrast enhanced computed tomography (CT) of the aorta and main branches for all the patients, also we calculated the body surface area according to the DuBois and DuBois formula. Results. We performed 838 minimally invasive on-pump procedures, which is 98.5% of all patients qualified for MICS. According to the results of the preoperative CT scan, 13 (1.5%) patients were not operated with the minimally invasive approach due to the hazards related to the provision of cardiopulmonary bypass. Peripheral cannulation was performed in 754 (90%) patients and an alternative cannulation site was selected in 62 (8.2%) patients based on preoperative CT data. There were 10 (1.32%) patients who developed major complications (stroke, acute aortic dissection, acute renal failure requiring hemodialysis) after peripheral cannulation. Conclusions. Preoperative CT scan is mandatory for planning a perfusion strategy in minimally invasive cardiac surgery. The required surgical techniques should include cannulation of the right and left femoral and right axillary arteries.

In patients with functional mitral regurgitation, the placement of a sling encircling both papillary muscles in conjunction with mitral annuloplasty appears to be a rational approach for surgical correction, because it addresses both the mitral valve and the deformities of the subvalvular mitral apparatus. Reports in the literature that describe the utilization of this technique are few, and mainly involve a median sternotomy approach. The purpose of this communication is to describe the technical details of performing this procedure via a minimally invasive approach.

AbstractSecondary deformities of repaired cleft lips are an unfortunate complication despite the meticulous approach of modern primary procedures. Most of these surgeries take place in the patient's early life and must be strategically planned to provide optimal cosmesis with minimal interventions. Depending on the level of severity, treatment of the secondary deformities ranges from noninvasive or minimally invasive techniques to complete revision cheiloplasty. Many novel topical, injectable, and laser therapies have allotted physicians more technical flexibility in treating superficial distortions. Nonetheless, surgical techniques such as diamond excision and adjacent tissue transfer remain popular and useful reconstructive modalities. Deformities involving the orbicularis oris must be completely taken down to allow full access to the muscle. Complete revision cheiloplasty requires recreation of the cleft defect and reconstruction similar to the primary repair. Due to the myriad of presentations of these secondary deformities, familiarity with the various treatments available is imperative for any cleft surgeon.

AimsAiming to reduce the numbers of high risk autopsies, we use a minimally invasive approach. HIV/hepatitis C virus (HCV)-positive coronial referrals, mainly intravenous drug abusers, have full autopsy only if external examination, toxicology and/or postmortem CT scan do not provide the cause of death. In this study, we review and validate this protocol.Methods and results62 HIV/HCV-positive subjects were investigated. All had external examination, 59 toxicology and 24 CT. In 42/62, this minimally invasive approach provided a cause of death. Invasive autopsy was required in 20/62, CT/toxicology being inconclusive, giving a potential rather than definite cause of death. Autopsy findings provided the cause of death in 6/20; in the remainder, a negative autopsy allowed more weight to be given to toxicological results previously regarded as inconclusive. In order to validate selection of cases for invasive autopsy using history, external examination and toxicology, a separate group of 57 non-infectious full autopsies were analysed. These were consecutive cases in which there was a history that suggested drug abuse. A review pathologist, provided only with clinical summary, external findings and toxicology, formulated a cause of death. This formulation was compared with the original cause of death, based on full autopsy. The review pathologist correctly identified a drug-related death or requirement for full autopsy in 56/57 cases. In one case, diagnosed as cocaine toxicity by the review pathologist, autopsy additionally revealed subarachnoid haemorrhage and Berry aneurysm.ConclusionsThese findings support the use of minimally invasive techniques in high risk autopsies, which result in a two-thirds reduction in full postmortems.

The application of minimally invasive surgery (MIS) to resect pediatric solid tumors offers the potential for reduced postoperative morbidity with smaller wounds, less pain, fewer surgical site infections, decreased blood loss, shorter hospital stays, and less disruption to treatment regimens. However, significant controversy surrounds the question of whether a high-fidelity oncologic resection of childhood cancers can be achieved through MIS. This review outlines the diverse applications of MIS to treat pediatric malignancies, up to and including definitive resection. This work further summarizes the current evidence supporting the efficacy of MIS to accomplish a definitive, oncologic resection as well as appropriate patient selection criteria for the minimally invasive approach.

Abstract BACKGROUND Epidural spinal cord compression (ESCC) is a common and severe cause of morbidity in cancer patients. Minimally invasive surgical techniques may be utilized to preserve neurological function and permit the use of radiation to maximize local control. Minimally invasive techniques are associated with lower morbidity. OBJECTIVE To describe a novel, minimally invasive operative technique for the management of metastatic ESCC. METHODS A minimally invasive approach was used to cannulate the pedicles of the thoracic vertebrae, which were then held in place by Kirschner wires (K-wires). Following open decompression of the spinal cord, cannulated screws were placed percutaneously with stereotactic guidance through the pedicles followed by cement induction. Stereotactic radiosurgery is performed in the postoperative period for residual metastatic disease in the vertebral body. RESULTS The minimally invasive technique used in this case reduced tissue damage and optimized subsequent recovery without compromising the quality of decompression or the extent of metastatic tumor resection. Development of more minimally invasive techniques for the management of metastatic ESCC has the potential to facilitate healing and preserve quality of life in patients with systemic malignancy. CONCLUSION ESCC from vertebral metastases poses a challenge to treat in the context of minimizing potential risks to preserve quality of life. Percutaneous pedicle screw fixation with cement augmentation provides a minimally invasive alternative for definitive treatment of these patients.
