BACKGROUND: The posterior retroperitoneoscopic adrenalec tomy has several advantages compared with the transperitoneal approach such as a shorter and more direct route to the target organ, no breach of the intraperitoneal space, and no required retraction of the adjacent organs. It also is a safe procedure with a short learning curve.1-5 This report presents a challenging case of an extra-adrenal paraganglioma located in the aorto-caval space and managed using the retroperitoneal approach...

BACKGROUND: An estimated 5 billion people worldwide lack access to basic surgical care. In particular, the vast majority of low- and middle-income countries (LMICs) currently struggle to provide adequate neurosurgical services. Significant barriers exist, including limited access to trained medical, nursing and allied health staff, lack of equipment, and availability of services at reasonable distance and at reasonable cost to patients. An accurate assessment of current neurosurgical capacity in LIMCs is an essential first step in tackling this deficit...

Surgeon controlled study of 200 cold/cold and 200 hot/hot tonsillectomy cases in one institution Hot/hot resulted in higher overall rates of early and late post-tonsillectomy haemorrhage and return-to-theatre when compared to cold/cold methods. Bipolar diathermy tonsillectomy resulted in a statistically significant higher rate of secondary post-tonsillectomy haemorrhage than cold-steel of nearly three times. Trainee surgeons performed better in bipolar haemostasis than cold-steel dissection with regard to post-operative morbidity...

REVIEW
Sepehr Feizi, Amir A Azari, Sharareh Safapour
Angiogenesis refers to new blood vessels that originate from pre-existing vascular structures. Corneal neovascularization which can lead to compromised visual acuity occurs in a wide variety of corneal pathologies. A large subset of measures has been advocated to prevent and/or treat corneal neovascularization with varying degrees of success. These approaches include topical corticosteroid administration, laser treatment, cautery, and fine needle diathermy. Since the imbalance between proangiogenic agents and antiangiogenic agents primarily mediate the process of corneal neovascularization, recent therapies are intended to disrupt the different steps in the synthesis and actions of proangiogenic factors...

PURPOSE: The purpose of this study was to develop intra-ocular diathermy forceps and test them on perfused porcine cadaver eyes. METHODS: We designed two types of 23-gauge intra-ocular bipolar diathermy forceps by modifying commercially available membrane peeling forceps. In the first type, the emitting electrode is connected to one-half of the core and the return electrode to the other half, with one jaw of the forceps attached to each half. In the second type, the emitting electrode is attached to the core and both jaws of the forceps, and the return electrode to the surrounding tube...

Low-intensity, unfocused, ultrasound-induced diathermy can produce undesired temperature increases at the interface of adjacent tissues within the body; particularly, at the interface of soft tissue and bone. This study provides a computational framework for predicting an upper bound on the temperature profile within a multiphase system composed of gel pad (water), tissue and bone from an input of acoustic energy, at frequencies and power levels consistent with applications of therapeutic hyperthermia. The model consists of solving a (one-dimensional) spatially discretized bioheat transfer equation via finite-difference method and updating the solution in time with a forward-Euler scheme...

This review focuses on oxidative stress and more specifically lipid peroxidation in cardiac surgery, one of the fundamental theories of perioperative complications. We present the molecular pathways leading to lipid peroxidation and integrate analytical methods that allow detection of lipid peroxidation markers in the fluid phase with those focusing on volatile compounds in exhaled breath. In order to explore the accumulated data in the literature, we present a systematic review of quantitative analysis of malondialdehyde (MDA), a widely used lipid peroxidation product at various stages of cardiac surgery...

Calyceal diverticula in children are rare and 20% eventually become symptomatic. Following the use of laparoscopic or endoscopic treatments, 85% of children report symptomatic relief. However, complete radiological resolution is seen only in three-fourths of the laparoscopic group and a quarter of those treated via endoscopy. Diathermy ablation of the lining and/or prolonged double J stenting has not altered this outcome. The robotic approach is superior to the other two techniques as the leak can be clearly identified and securely suture ligated...

Intraoperative bleeding is one of the main severe complications in complete video-assisted thoracic surgery (c-VATS) and post-operative air-leaks prevention still represents an important challenge. Usually, hemostasis is often difficult and unsafe when the VATS approach is performed and the potential role of bipolar sealing devices is still undefined, as proven by limited experiences reported in the literature. By introducing endostaplers in VATS surgery, it was possible to perform safe thoracoscopic resections of lung...

PURPOSE: It is well known that blood perfusion is important for the survival of skin flaps. As no study has been conducted to investigate how the blood perfusion in human eyelid skin flaps is affected by the flap length and diathermy, the present study was carried out to investigate these in patients. METHODS: Fifteen upper eyelids were dissected as part of a blepharoplastic procedure, releasing a 30-mm long piece of skin, while allowing the 5 mm wide distal part of the skin to remain attached, to mimic a skin flap (hereafter called a "skin flap")...

STUDY DESIGN: Benchtop model with prospective surgeon video testing. OBJECTIVE: To create a surface bleeding severity scale, the SPOT GRADE (SG), for quantitative assessment of target bleeding site (TBS) blood loss. This is of particular interest for spinal surgery due to epidural bleeding and an inability to use diathermy and radiofrequency cautery close to nerve roots. SUMMARY OF BACKGROUND DATA: A novel apparatus perfusable at known flow rates and simulating different sized wounds was used to create movies to educate surgeons on specific degrees of bleeding...

Adipose tissue biopsies offer tissue samples that, upon analysis, may provide insightful overviews of mechanisms relating to metabolism and disease. To obtain subcutaneous adipose tissue biopsies in the abdominal area, researchers and physicians use either a surgical or a needle-based technique. However, surgical subcutaneous fat biopsies can offer tissue samples that may provide a more comprehensive overview of the complexities of biological indices in white adipose tissue. Usually, a surgical adipose tissue biopsy includes a diathermy treatment for cauterizing blood vessels to prevent excessive bleeding...
