Simultaneous resection of gastric and gallbladder metastasis from renal cell carcinoma treated by laparoscopic and endoscopic cooperative surgery: a case report.

Background: Metastases to the stomach or gallbladder from any malignancy is rarely noted, and simultaneous metastases to both organs are atypical. We present a unique case of simultaneous multifocal metastases of the stomach and gallbladder from renal cell carcinoma (RCC).

Case Presentation: The case involved a 60-year-old man, with a past history of RCC (clear cell type, G2, T1b N0 M0 Stage I) treated by a right nephrectomy.

A case of gastric hamartomatous inverted polyp resected endoscopically.

We report the case of a 55-year-old woman with a tumor in the greater curvature of the upper gastric body. The tumor was incidentally found on an upper gastrointestinal X-ray series performed during a routine medical examination. Whereas endoscopy revealed a gastric submucosal tumor (SMT), endoscopic ultrasonography demonstrated a heterogeneous tumor with small, cystic, hypoechoic spots originating from the second layer.

Endoscopic transgastric drainage of a gastric wall abscess after endoscopic submucosal dissection.

A 63-year-old woman was referred to our hospital for further examination because of an incidental finding of early gastric cancer. Endoscopic submucosal dissection (ESD) was successfully performed for complete resection of the tumor. On the first post-ESD day, the patient suddenly complained of abdominal pain after an episode of vomiting.
