Minimally Invasive Surgical Treatment

The aim of the research is to study the results of minimally invasive surgery for the treatment of nonspecifi c infectious spine lesions, and to present personal experience. Material and methods. Three patients with purulent nonspecifi c spondylodiscitis of lumbar spine got minimally invasive surgical treatment. The essence of surgical intervention included X-ray-assisted placement of tubular retractors in the area of intervertebral disc aff ected by purulent process; debridement and irrigation with antiseptic solution of interbody space, and setting a drain tube. All patients were treated during the period from December 2016 to February 2019. They were examined before surgery and in 3 months aft er the discharge. Laboratory parameters (CBT, C-reactive protein, bacteriological analysis of intervertebral disc contents) and instrumental research methods (computer tomography, magnetic resonance imaging) were evaluated. ODI, VAS, SF-36 questionnaires helped to assess pain syndrome and life quality of patients. Results. In 100 % of studied cases infection was caused by Staphylococcus aureus. The result of treatment in all cases was assessed as good, because pain syndrome, neurological disorders and inflammatory process were arrested; there were no signs of disease progression. In all cases, life quality of patients was restored. In one case, additional surgical intervention was required (posterior instrumental fi xation of spine) because of instability signs. Conclusion. Minimally invasive surgical treatment of purulent single-level spondylodiscites can be recommended for practical use. The use of such approache allows to verify purulent infection agent, to damage soft tissues less getting proper sanitation of interbody space. It also allows to stop the infection and restore life quality of a patient

Acute Epidural Hematoma

Background and Objective. Although minimally invasive surgical treatment of acute epidural hematoma attracts increasing attention, no generalized indications for the surgery have been adopted. This study aimed to evaluate the effects of minimally invasive surgery in acute epidural hematoma with various hematoma volumes.Methods. Minimally invasive puncture and aspiration surgery were performed in 59 cases of acute epidural hematoma with various hematoma volumes (13–145 mL); postoperative follow-up was 3 months. Clinical data, including surgical trauma, surgery time, complications, and outcome of hematoma drainage, recovery, and Barthel index scores, were assessed, as well as treatment outcome.Results. Surgical trauma was minimal and surgery time was short (10–20 minutes); no anesthesia accidents or surgical complications occurred. Two patients died. Drainage was completed within 7 days in the remaining 57 cases. Barthel index scores of ADL were ≤40 (n=1), 41–60 (n=1), and >60 (n=55); scores of 100 were obtained in 48 cases, with no dysfunctions.Conclusion. Satisfactory results can be achieved with minimally invasive surgery in treating acute epidural hematoma with hematoma volumes ranging from 13 to 145 mL. For patients with hematoma volume >50 mL and even cerebral herniation, flexible application of minimally invasive surgery would help improve treatment efficacy.

Minimally Invasive Surgical Treatment

This article is devoted to the results of applying the original minimally invasive surgical technique for the treatment of chronic internal hemorrhoids. The purpose of the study is to improve the outcomes of treatment in patients with chronic internal hemorrhoids by the simultaneous use of pathogenically substantiated low-traumatic surgical methods: dearterialization of internal hemorrhoids with Doppler guidance and clamping with latex rings. Materials and methods. Study included 204 patients with chronic hemorrhoids of the II–III degree, divided into 3 groups depending on the technique of minimally invasive surgery. The standard research methods for coloproctology were used. Results. It was found that the best short-term and long-term results of the surgical treatment of chronic internal hemorrhoids were obtained using the combined surgical technique proposed by the authors. Conclusions. The proposed combination of minimally invasive surgery may be the method of choice in the surgical treatment of chronic hemorrhoids of the II–III degree.

Abstract Background Minimally invasive surgery (MIS) procedures cause less trauma to the patient and might improve recovery. This study aimed to determine the efficacy and safety of condylectomy with MIS to treat interdigital corns of the lesser toes. Methods This prospective cohort study was conducted in seven podiatry centers. Patients with interdigital corns of the lesser toes, progressing for more than a year, with one or more recurrences in the last year following conservative treatments were eligible. The recruited patients were classified according to their treatment: conservative or surgical (condylectomy with MIS) and were compared. Patient satisfaction, pain, the clinical and functional status of the foot and the appearance of sequelae were assessed at 3 and 6 months after treatment. Results At 6 months, patients in the surgical treatment group showed no pain on pressure, which significantly differed from the conservative treatment group (p <  0.001). They also improved clinical and functional status of the foot, reaching values comparable to those of the standard population. No paresthesia, joint stiffness or instability, toe malalignment, or corn transfer to a contiguous site resulted from the surgical treatment. Conclusions Condylectomy with MIS is effective and safe to treat interdigital corns of the lesser toes.

Inverse Kinematics Problem

A crucial design challenge in minimally invasive surgical (MIS) robots is the provision of a fully decoupled four degrees-of-freedom (4-DOF) remote center-of-motion (RCM) for surgical instruments. In this paper, we present a new parallel manipulator that can generate a 4-DOF RCM over its end-effector and these four DOFs are fully decoupled, i.e., each of them can be independently controlled by one corresponding actuated joint. First, we revisit the remote center-of-motion for MIS robots and introduce a projective displacement representation for coping with this special kinematics. Next, we present the proposed new parallel manipulator structure and study its geometry and motion decouplebility. Accordingly, we solve the inverse kinematics problem by taking the advantage of motion decouplebility. Then, via the screw system approach, we carry out the Jacobian analysis for the manipulator, by which the singular configurations are identified. Finally, we analyze the reachable and collision-free workspaces of the proposed manipulator and conclude the feasibility of this manipulator for the application in minimally invasive surgery.
