BACKGROUND The goal of this study was to determine whether there are correlations between various options of surgical treatment and long-term outcome for spinal osteosarcoma. METHODS This was a retrospective review of 16 patients with spinal osteosarcoma, who underwent surgical treatment from 1999 to 2010. Seven patients were given total en bloc spondylectomy (TES), while nine received piecem...
BACKGROUND There is no standard surgical approach for the management of retroperitoneal sarcoma. The aim of this clinical study was to describe the experience of an anterior approach to en bloc resection in left-sided retroperitoneal sarcoma with adjacent organ involvement. MATERIAL AND METHODS This retrospective clinical study included 25 patients who were diagnosed with left-sided retroperito...
(LSTs) are found frequently in the colon but not in other sections of the gastrointestinal tract. These tumors are usually less invasive than protruding or depressed tumors of the same size; thus, we have much freedom in selecting treatment modalities for LSTs. However, a pitfall lurks in the technical difficulties. It is preferable to resect every single tumor in one piece if possible, since e...
Background and study aims The pocket-creation method (PCM) is a novel strategy for endoscopic submucosal dissection (ESD). The aim of this study is to determine the efficacy of the PCM for colorectal laterally spreading tumors, non-granular type (LST-NG). Patients and methods The records of 126 consecutive patients with colorectal LST-NG who underwent ESD between April 2012 and July 2015 were r...
To meet the requirement of extensive resection of pancreatic cancer with portal or mesenteric venous invasion, the innovation of Vascular Graft Bridged En Bloc Resection (VGBEBR) has been adopted to treat advanced biliopancreatic cancer in the Department of Hepatobiliary Surgery of the PLA Rocket Force General Hospital since 2013. This attempt could not only broaden surgical indications of radi...
Background: Giant cell tumor (GCT) of the bone is a benign neoplasm with local aggressive behavior. Distal ulna is a very rare place for GCT. Published studies have mainly focused on case reports, and thus there is no consistent treatment strategy for this tumor at this location. This retrospective study was conducted to evaluate the oncological and functional results of 2 di...
Aim: The aim of this study was to examine the safety and efficacy of endoscopic submucosal dissection (ESD) for early gastric cancer based on approximately 10 years’ experience. Methods: Endoscopic submucosal dissection was performed in 1272 patients with early gastric cancer (1657 lesions). We examined en bloc resection rate, curative resection rate, local recurrence rate, procedure time, and ...
BACKGROUND Epithelioid hemangioendothelioma (EHE) is a rare vascular tumor with malignant biological behavior. It arises from endothelial cells, usually within soft tissues, and can occur in almost all locations. CASE REPORT We report a unique case of a 25-year-old man who presented with sudden attacks of severe back pain followed by acute non-traumatic paraplegia. Emergency diagnostics revea...
Laparoscopy for liver resection is a highly specialized field, as laparoscopic liver surgery presents severe technical difficulties. However, the recent rapid development of technological innovations, improvements in surgical skills and the accumulation of extensive experience by surgeons have improved the feasibility and safety of a laparoscopic approach for properly selected patients [1]. Sin...
Background and study aims Rectal neuroendocrine tumors grade 1 (NET G1; carcinoid) ≤ 10 mm in diameter often extend into the submucosa, making their complete histological resection difficult using endoscopic techniques. Endoscopic submucosal resection with a ligation device (ESMR-L) and endoscopic submucosal dissection (ESD) are commonly used to overcome these difficulties. We also previously ...
