Stereotactic body radiation therapy (SBRT) stems from the initial developments of intra-cranial stereotactic radiosurgery (SRS). Despite similarity in their names and clinical goals of delivering a sufficiently high tumoricidal dose, maximal sparing of the surrounding normal tissues and a short treatment course, SBRT technologies have transformed from the early days of body frame-based treatments with X-ray verification to primarily image-guided procedures with cone-beam CT or stereoscopic X-ray systems and non-rigid body immo-bilization...

Rana Alhossaini, Woo Jin Hyung
Situs inversus totalis (SIT) is a relatively rare condition where the abdominal and/or thoracic organ is positioned as a "mirror image" of the normal position. We are presenting a video of robotic distal gastrectomy performed in a 52-year-old female known to have SIT. Preoperative investigations revealed the patient has an early gastric cancer at the antrum. Ports were placed as mirror image to our usual port placement and upon exploration, the liver is visualized on the left side of the abdomen and the spleen is on the right...

Laparoscopy is considered the gold standard approach to perform left lateral sectionectomy (LLS). Furthermore, laparoscopy for cirrhotic patients can reduce intraoperative bleeding and postoperative morbidity when compared to open surgery. Although robotic surgery is feasible for both minor and major liver resections, it remains a work in progress and only few series reported this approach for cirrhotic patients. We reported two cases of 62-year-old men, both with hepatitis C virus and alcoholic cirrhosis, but with compensated liver functions (MELD 9-10 and Child-Pugh A5-A6)...

The laparoscopic approach has gained acceptance in the field of hepatopancreaticobiliary surgery. It offers several advantages including reduced blood loss, reduced postoperative pain, and shorter length of stay. However, long operating times can be associated with surgeon and assistant fatigue and image tremor. Robotic camera holders have been designed to overcome these drawbacks but may come with significant costs. The aim of this study was to economically evaluate their use compared with standard assistants using a single surgeon consecutive series of laparoscopic liver resections from January 2014 to May 2015...

Robotic needle steering will improve percutaneous radio-frequency ablation (RFA) in the liver by performing distributed ablations without requiring multiple punctures of the liver capsule, thus enabling the treatment of large or multifocal tumors. However, state-of-the-art asymmetric-tip robotic needle steering systems do not yet achieve clinically relevant curvature. This work presents the design and development of a highly articulated needle that enables distributed RFA in liver tissue under ultrasound (US) image guidance...

BACKGROUND: Epithelioid haemangioendothelioma (EHE) is a rare low-grade vascular neoplasm that can arise in the lung, liver, soft tissues or, less commonly, bone. Due to its low prevalence of less than one in a million and its non-specific clinical features, EHE is often misdiagnosed and managed inappropriately. Here we discuss the case of a 58 year-old gentleman with mediastinal EHE and review existing literature on pulmonary EHE (PEH). CASE HISTORY: A 58 year-old gentleman presented to our outpatient Clinic with chest discomfort and palpitations...
