Methodological Problems

Quantitative positron emission tomography (PET) brain studies often require that the input function be measured, typically via arterial cannulation. Image-derived input function (IDIF) is an elegant and attractive noninvasive alternative to arterial sampling. However, IDIF is also a very challenging technique associated with several problems that must be overcome before it can be successfully implemented in clinical practice. As a result, IDIF is rarely used as a tool to reduce invasiveness in patients. The aim of the present review was to identify the methodological problems that hinder widespread use of IDIF in PET brain studies. We conclude that IDIF can be successfully implemented only with a minority of PET tracers. Even in those cases, it only rarely translates into a less-invasive procedure for the patient. Finally, we discuss some possible alternative methods for obtaining less-invasive input function.

Sensory Evoked

We previously reported on evoked potentials elicited by electrical stimulation of the superior laryngeal nerve at an appropriate site on the dural surface as a reflection of activities in the brain stem and cortex in anesthetized cats. This evoked potential was called the laryngeal sensory evoked potential (LSEP). In this study we attempted to establish a less invasive procedure for measuring LSEP. The procedures were recording on the scalp using chloride-coated silver disk electrodes and stimulation by insertion of a bipolar platinum hooked wire electrode into the laryngeal mucosa. Evoked potentials could be detected using these less invasive procedures. The response morphologies and relative timing of LSEP components were quite similar for each method in a given cat. However, the amplitudes were slightly lower and the latencies were slightly prolonged with the less invasive techniques. These results suggest that this LSEP method might be applicable to human beings as a noninvasive method for evaluating the function of the laryngeal sensory pathway

Surgical Myectomy

The surgical myomectomy for hypertrophied myocardium in patients with HOCM is a well-established and evidence-based treatment modality. However, with the drawback of exposing the patient to major surgery and prolonged post-operative periods, cardiologists together with their surgical peers found the advent of a potentially less invasive procedure. This has been accomplished by the installation of alcohol through the coronary arteries in order to shrink the diseased and hypertrophied muscle area with an aim to alleviate the symptoms in the first instance if not completely curing the pathology as an endeavor goal. Nevertheless, with this invention, a few complications have started to emerge. The main drawback was heart block, which could require permanent pacemaker insertion in most of the cases. In the interim, there is no clear pathway or guideline to decide which treatment option would be the best, and there is no certain inclusion or exclusion criteria incorporate patients who can undergo either one of the modalities. In this review, four studies were scrutinized to investigate the major consequences of each route, especially focusing on the proportion of complete heart block. Also, the role of MRI in the delineation of the resected area either surgically or by alcohol administration is studied in detail. After reviewing these articles, it has been concluded that despite alcohol septal ablation being less invasive approach, surgical therapy remains the preferred treatment modality and it is preferred treatment modality and so far, it is the gold standard option in the management of hypertrophic obstructive cardiomyopathy. Nevertheless, it could not be overlooked the lack of strong RCTS in such area which could be one of the main points that future trialists need to consider.

Submucosal Dissection

Abstract Background Endoscopic submucosal dissection (ESD) is increasingly applied for early gastric cancer. ESD is a less invasive procedure and could be a radical treatment. However, in some cases, ESD cannot be completed owing to patient or technical factors. In such cases, which could have the potential for curative resection with ESD, standard gastrectomy is excessively invasive. Through closed laparoscopic and endoscopic cooperative surgery (LECS), gastric tumor can be precisely resected without exposing tumor cells to the abdominal cavity. Compared with standard gastrectomy, closed LECS is less invasive for the treatment of early gastric cancer. Case presentation We performed closed LECS for three cases of early gastric cancer after failed ESD. In all three cases, ESD was interrupted owing to technical and patient factors, including perforation, respiratory failure, and carbon dioxide narcosis. All three cases successfully underwent closed LECS with complete tumor resection and showed an uneventful postoperative course. All three patients remain alive and have experienced no complications or recurrence, with a median follow up of 30 (14–30) months. Conclusions Closed LECS is less invasive and useful procedure for the treatment of early gastric cancer, particularly in cases with difficulty in ESD.

Aims The traditional transosseus flexor hallucis longus (FHL) tendon transfer for patients with Achilles tendinopathy requires two incisions to harvest a long tendon graft. The use of a bio-tenodesis screw enables a short graft to be used and is less invasive, but lacks supporting evidence about its biomechanical behaviour. We aimed, in this study, to compare the strength of the traditional transosseus tendon-to-tendon fixation with tendon-to-bone fixation using a tenodesis screw, in cyclical loading and ultimate load testing. Materials and Methods Tendon grafts were undertaken in 24 paired lower-leg specimens and randomly assigned in two groups using fixation with a transosseus suture (suture group) or a tenodesis screw (screw group). The biomechanical behaviour was evaluated using cyclical and ultimate loading tests. The Student’s t-test was performed to assess statistically significant differences in bone mineral density (BMD), displacement, the slope of the load-displacement curves, and load to failure. Results The screw group showed less displacement (loosening) during cyclical loading, which was significant during 300, 500, 600, 700, 800, 900, and 1000 cycles (p < 0.05: other cycles: 0.079 < p < 0.402). Compared with the suture group, the screw group had higher mean ultimate load values (133.6 N, sd 73.5 vs 110.1 N, sd 46.2; p = 0.416). Conclusion Fixation of the FHL tendon with a tenodesis screw enables a less invasive procedure to be undertaken and shows similar biomechanical behaviour and primary strength compared with fixation using a transosseus suture.

AbstractArthroplasty is used when there is irreversible damage to the articular cartilage of the knee. It involves implanting a bicompartimental (femoral and tibial components) or a tricompartimental (femoral, tibial and patellar components) prosthesis. It is a very invasive and costly operation, so our objective was to evaluate the necessity of the patellar component.Material and methods: During our study we’ve included 39 patients: in 27 cases we used tricompartimental prosthesis, while the other 12 received only the bicompartimental components. Patients were evaluated preoperatively and postoperatively using the International Knee Documentation Comitee score. We’ve also compared our results with the results of other published authors.Results: We’ve found that there is little to no difference between the two groups regarding mobility and complication, however patients with bicompartimentalarthroplasty complained of less pain.Conclusion: We’ve found that bicompartimentalarthroplasty – being a less invasive procedure – is better not only in terms of pain management, but there is also less hemorrhaging, shorter intraoperative time is considered, revision is easier and also has financially advantages, both for the patient and for the medical facility.
