AIM To determine whether there is a correlation between the location of the lesion and endoscopic submucosal dissection (ESD) outcome. METHODS From January 2008 to December 2010, ESD of 1443 gastric tumors was performed. En bloc resection rate, complete resection rate, procedure time and complication rate were analyzed according to the tumor location. RESULTS The rates of en bloc resection ...

Angiosarcomas are rare malignant vascular tumors that comprise only approximately 2% of all soft tissue sarcomas. They are mainly located in the head and neck area and spinal involvement is particularly very uncommon, reported only in occasional case reports or as single cases as part of a clinical series. There is therefore limited data in the literature regarding the optimum treatment strateg...

Gastrocolic fistula (GCF) is associated with a variety of diseases, but in recent years it has most frequently been observed with gastric or colonic malignancy. The management of primary tumor lesions and optimal surgical treatment strategies remain controversial. In this study, we explore the clinical diagnosis and treatment of GCF by retrospectively analyzing the records of GCF patients treat...

Background: Colorectal carcinomas (CRCs) arise from premalignant precursors in an adenoma‐carcinoma sequence, in which adenoma with high‐grade dysplasia (HGD) and early‐stage carcinoma are defined as advanced neoplasia. A limited number of studies have evaluated the long‐term outcomes of endoscopic submucosal dissection (ESD) for advanced colorectal neoplasia. This study aimed to assess the eff...

PURPOSE Additional surgery is commonly recommended in gastric cancer patients who have a high risk of lymph node metastasis or a positive resection margin after endoscopic resection. We conducted this study to determine factors related to residual cancer and to determine the appropriate treatment strategy. MATERIALS AND METHODS A total of 28 patients who underwent curative gastrectomy due to ...

BACKGROUND Inferior vena cava (IVC) leiomyosarcoma is a rare tumor of smooth muscle origin. It is often large by the time of diagnosis and may involve adjacent organs. A margin-free resection may be curative, but the resection must involve the tumor en bloc with the affected segment of vena cava and locally involved organs. IVC resection often requires vascular reconstruction, which can be done...

OBJECTIVE The treatment of patients with non-small cell lung cancer invading the parietal pleura or chest wall is still debated. It is unsolved whether the depth of chest wall involvement or the type of resection (extrapleural or en bloc) affects long-term survival. METHODS design, retrospective analysis; setting, Hyogo Medical Center for Adults, patients: the 97 patients who underwent surgic...

BACKGROUND Endoscopic mucosal resection (EMR) is simple and quick and has low complication rates. However, the disadvantage of local recurrence or remnant rate limits the use of this technique. We aimed to analyse the outcomes of conventional EMR and EMR with circumferential incision (CIEMR), a simplified modification of EMR, in the endoscopic treatment of rectal carcinoid tumours. METHODS A ...
