A 63-year-old male was referred to our hospital with two existing lesions in bilateral lungs. Computed tomography (CT) showed a 15-mm ground-glass opacity (GGO) in the superior segment of left lower lung (S6) and a 5-mm GGO in the center of the right upper lobe. The preoperative clinical diagnosis was stage I primary lung cancer for the left lesion while the right lesion needed follow-up. Uniportal video-assisted thoracic surgery (VATS) left superior segmentectomy in the semiprone position was performed in this case and the right upper lobe was kept untouched...

This video demonstrates surgical techniques of the occipital transtentorial approach to a pineal region tumor without using a fixed brain retractor, which may cause functional impairment or even tissue injury to the occipital visual cortex. There are several ways to facilitate retractorless surgery through this approach. A lateral-semiprone positioning of the patient can induce gravity retraction. The brain is relaxed by draining CSF fluid through lumbar drainage or lateral ventricular tap in the case of obstructive hydrocephalus...

Intralobar pulmonary sequestration (IPS) is a rare developmental abnormality of the lower respiratory system. Lobectomy by video-assisted thoracic surgery using a three-port or four-port technique is the generally accepted operative approach. However, lobectomy can also be accomplished with a single incision even if the IPS is large. This report describes the first case of a patient with a large IPS undergoing uniportal video-assisted thoracic lobectomy in a semiprone position.

INTRODUCTION: Surgical resection with curative intent is till the mainstay of treatment for resectable esophageal cancer. Minimal invasive oesophagectomy has the potential to lower morbidity and mortality. In all likelihood, thoracoscopic oesophagectomy in semiprone position gives all the benefits of prone position and can be converted to thoracotomy without change in patient position if needed. The aim of this study is to analyze the feasibility of thoracoscopic oesophagectomy in semiprone position...

BACKGROUND: Hepatic tumors in the lower edge and lateral segments are commonly treated by laparoscopic liver resection. Tumors in the anterosuperior and posterior segments are often large and locally invasive, and resection is associated with a higher risk of insufficient surgical margins, massive intraoperative bleeding, and breaching of the tumor. Laparoscopic surgery for such tumors often involves major hepatectomy, including resection of a large volume of normal liver tissue. We developed a novel method of laparoscopic resection of tumors in these segments with the patient in the semiprone position, using a dual-handling technique with an intercostal transthoracic port...

BACKGROUND: Pure laparoscopic liver resection is technically difficult for tumors located in the dorsal anterior and posterior sectors. We have developed a maneuver to perform pure laparoscopic hepatectomy in the semiprone position which was developed for resecting tumors located in these areas. METHODS: The medical records have been reviewed retrospectively in 30 patients who underwent laparoscopic liver resection in the semiprone position for carcinoma in the dorsal anterior or posterior sectors of the right liver between 2008 and 2011...

We describe a 54-year-old man in whom esophageal carcinoma was diagnosed and who underwent video-assisted thoracoscopic surgery of the esophagus (VATS-E) in the prone position. Initially, the patient was fixed in a semiprone position, from which he could be rotated to a prone or left lateral position. Four ports were inserted, and then the patient was rotated to the prone position. Once the patient was prone, gravity caused the lung to move downwards. Next, the chest cavity was inflated with a CO(2) insufflation pressure of 6 mm Hg...

The fully prone position, once used in surgery for chronic inflammatory lung diseases, has become obsolete. In the last 2 years, a modified semiprone position was used for video-assisted thoracoscopic surgery in 358 patients undergoing lobectomy with mediastinal complete lymphadenectomy The ports were placed with the patient in the lateral decubitus position. The patient was rotated 45-60 degrees towards the surgeon, giving enhanced exposure of the posterior mediastinum, esophagus, subcarinal and paratracheal spaces, due to displacement of the lung under gravity away from the operative field...

PURPOSE: Intra-articular screw penetration is one complication of volar plate fixation of distal radius fractures. This study was designed to determine the most commonly used imaging techniques and views during volar plating of distal radius fractures and to evaluate surgeons' ability to detect intra-articular screw placement on static fluoroscopic images and rotational fluoroscopy. METHODS: Active members of the American Society for Surgery of the Hand were polled regarding preferred imaging techniques (fluoroscopic vs cassette radiographs) and views (rotational fluoroscopy or static orthogonal/anatomic tilt/semipronated imaging) during volar plating of distal radius fractures...

BACKGROUND: Fracture of the scaphoid is the most common fracture of a carpal bone. Nevertheless, the diagnosis of SF might be challenging. Plain X-rays that fail to demonstrate a fracture line while clinical findings suggest the existence of such a fracture is not uncommon. Currently there is no consensus in the literature as to how a clinically suspected SF should be diagnosed, immobilized and treated. OBJECTIVES: To assess the current status of diagnosis and treatment of clinically suspected scaphoid fractures in Israeli emergency departments...

The deep-seated location of pineal parenchymal tumors (PPTs) and their associations with critical structures make their surgical resection technically challenging; further, the rarity of PPTs and repeated changes in their histopathological diagnostic criteria makes the study of their biological behavior and clinical outcomes difficult. Here, we describe the surgical techniques and results of an occipital transtentorial approach for PPTs together with the results in the clinicopathological study of PPTs. Since 1982, we have treated 93 patients with pineal region tumors, including 17 PPTs, with the occipital transtentorial approach using the lateral semiprone position...
