Carpal tunnel syndrome is one of the most common diseases in hand surgery. The gold standard in therapy is the surgical release of the carpal tunnel. We provide a brief update on the relevant pathogenesis, diagnosis and therapy and discuss questions related to minimal invasive decompression of the median nerve. Together with a review of the current literature, we report on our experiences in minimally invasive carpal tunnel release via a monoportal endoscopic access in over 700 cases. In conclusion, the endoscopic technique provides superior convalescence and patient safety is comparable to open methods...

Bariatric surgery has proven benefits for morbid obesity and its associated comorbidities. Laparoscopic approach is well established for bariatric surgery. Single-incision laparoscopic surgery (SILS) offers even more minimally invasive approach for the same with the added advantage of better cosmesis. We have developed and standardised the SILS approach at our institute. We share our experience and technical "tips" and modifications which we have learnt over the years. Technical details of performing sleeve gastrectomy and Roux-en-Y gastric bypass with special attention to liver retraction, techniques of dissection in difficult areas, creation of anastomoses and suturing have all been described...

Background: Thrombocytosis is triggered by and promotes tumor growth. The relationship between the change in circulating platelets after chemoradiation therapy (CRT) or adjuvant temozolomide (TMZ) and survival in glioblastoma remains unclear. We hypothesized that an increase in platelets after these treatments would be predictive of a shorter survival. Methods: We retrospectively reviewed data on 122 patients with newly diagnosed, pathologically proven glioblastoma who had been treated with surgery, followed by CRT and adjuvant TMZ, from 2007 to 2016...

For those individuals with upper-extremity amputation, a daily normal living activity is no longer possible or it requires additional effort and time. With the aim of restoring their sensory and motor functions, theoretical and technological investigations have been carried out in the field of neuroprosthetic systems. For transmission of sensory feedback, several interfacing modalities including indirect (non-invasive), direct-to-peripheral-nerve (invasive), and cortical stimulation have been applied. Peripheral nerve interfaces demonstrate an edge over the cortical interfaces due to the sensitivity in attaining cortical brain signals...

We describe an imaging approach based on an optical setup made up of a miniature, lensless, minimally invasive endoscope scanning a sample and matching post processing techniques that enables enhanced imaging capabilities. The main scopes of this article are that this approach enables imaging beyond highly scattering medium and increases the resolution and signal to noise levels reaching single cell imaging. Our approach has more advantages over ordinary endoscope setups and other imaging techniques. It is not mechanically limited by a lens, the fiber can acquire images over long time periods (unlike current imaging methods such as OCT etc...

BACKGROUND: "Advanced Core Decompression" (ACD) is a new technique for treatment of osteonecrosis of the femoral head (ONFH) that includes removal of the necrotic tissue using a percutaneous expandable reamer followed by refilling of the drill hole and the defect with an injectable, hard-setting, composite calcium sulphate (CaSO4)-calcium phosphate (CaPO4) bone graft substitute. As autologous bone has been shown to be superior to all other types of bone grafts, the aim of the study is to present and evaluate a modified technique of ACD with impaction of autologous bone derived from the femoral neck into the necrotic defect...

OBJECTIVE: Photodynamic therapy (PDT) was used as therapy for early neoplasia associated with Barrett's oesophagus (BE). This is 5-year follow-up of patients enrolled into randomised controlled trial of 5-aminolaevulinic acid (ALA) vs. Photofrin PDT. METHODS: Biopsies were taken from original Barrett's segment during endoscopic follow up using Seattle protocol. Endoscopic mucosal resection (EMR) ± radiofrequency ablation (RFA) was preferred therapy in patients who failed PDT and/or had recurrent neoplasia...

A central component of percutaneous nephrostolithotomy is an endoscopic lithotrite that safely and efficiently clears stone of all compositions from the intrarenal collecting system. The current multicenter trial studied 3 lithotrite combinations employing both mechanical ballistic and ultrasonic energy to fragment and evacuate with suction stone debris. What is clear from this work is that, with regard to the timely clearance of the stone burden and peri-operative complications, there is minimal difference between the devices studied, nothing special and nothing new...

Laparoscopic minimally invasive gynecologic surgery (MIGS) for benign conditions results in decreased morbidity, and faster recovery, compared with laparotomy. Tissue fragmentation by electromechanical morcellation permits the removal of large specimens through small laparoscopic incisions. Since the US Food and Drug Administration (FDA) published its safety warning about the risk of power morcellators spreading cancer during fibroid surgery in 2014, power morcellation has become rare. MIGS for fibroids and other large tissue specimens has declined...

Surgical repair of extensive thoracic aortic disease induced by repeated aortic dissection is challenging due to its invasive nature in some cases. We report a rare case of successful endovascular repair of a dissected 3-channelled thoracic aortic aneurysm using the PETTICOAT (provisional extension to induce complete attachment) technique and false-lumen embolization (the candy-plug technique). The PETTICOAT technique improved visceral flow, and the false lumen of the aneurysm was completely thrombosed by the candy-plug technique...

Aims: We hypothesized that the absence of a decrease in minimal left ventricular (LV) pressure during exercise would be associated with impaired LV apical back rotation during exercise. Methods and results: A total of 21 patients (59 ± 10 years) underwent invasive LV pressure measurements and simultaneous echocardiography at rest and during submaximal supine bicycle exercise. Patients were classified according to the changes in minimal LV pressure from rest to maximal exercise (Δminimal LVP); Group 1 (n = 8) had a decrease in minimal LV pressure with exercise, whereas Group 2 (n = 13) had an increase in minimal LV pressure...

BACKGROUND: Traumatic thoracoabdominal injuries can involve multiple organs and multiple cavities, which increases the complexity of surgical management. Traditionally, these injuries required laparotomy and thoracotomy. However, minimally invasive intervention may be reasonable for stable patients. MATERIALS AND METHODS: We present a case of a thoracoabdominal gunshot wound resulting in multiorgan, multicavity injury to the lung, diaphragm, and liver. We performed hepatorrhaphy and diaphragm repair, and addressed a retained hemothorax through a transabdominal laparoscopic approach...

High Intensity Focused Ultrasound (HIFU) is an emerging therapeutic solution that enables non-invasive treatment of several pathologies, mainly in oncology. On the other hand, accurate targeting of moving abdominal organs (e.g., liver, kidney, pancreas) is still an open challenge. This paper proposes a novel method to compensate the physiological respiratory motion of organs during HIFU procedures, by exploiting a robotic platform for ultrasound-guided HIFU surgery provided with a therapeutic annular phased array transducer...

A new controversy is raising in cardiovascular surgery, whether or not the new generation transcatheter valves used for valve implantation are superior to surgical techniques used for traditional valve replacement. If such a debate is far from being an issue for mitral valve treatment, where minimal invasive, (robotic or video-assisted) mitral valve repair has become the gold standard for mitral valve treatment while transcatheter mitral valve solutions are lagging behind(1-4), there are many voices stating that the future of aortic valve treatment will mainly be transcatheter(5)...

PURPOSE: Recently, conservative approaches such as wide local excisions and neoadjuvant chemotherapy are being considered to select young adult females with gynecologic RMS who have strong desire to preserve fertility. This analysis aims to identify prognosticators affecting survival outcomes and defining potential candidacy for fertility-preservation. Another focus is to explore the role of chemotherapy in reducing the need for aggressive surgery and the role of radiotherapy in decreasing rates of local failure...

INTRODUCTION: Even if different surgical approaches for total knee arthroplasty are well known since decades, the standard medial parapatellar incision remains the most common one; general agreement about significant advantages with minimally invasive techniques is lacking. Furthermore, the surgical stress effect on the organism has always been analyzed through blood inflammatory parameters. This study aim was to compare the standard and subvastus approaches, using the salivary cortisol in particular as measure for systemic surgery-related stress...

Background: Distal tibial fractures are common injuries that are prone to complications and require careful management. The use of medial periarticular locking plates is an established modality in the treatment if these fractures. These plates are inserted using the minimally invasive plate osteosynthesis (MIPO) or open technique. Our study looks at the soft tissue complications associated with the use of medial locking plates in the management of these fractures. Methods: This was a retrospective study carried out at a tertiary care university hospital in an urban setting...
