[A Resected Case with Early Gastric Cancer That Was Overdiagnosed as Scirrhous Gastric Cancer].

We experienced a case of early gastric cancer. A 69-year-old woman with a thick gastric wall, thickened folds, and undifferentiated cancer cells in biopsy was diagnosed with scirrhous gastric cancer. The patient underwent total gastrectomy for scirrhous gastric cancer and was found to have only an early gastric cancer lesion located on the upper gastric wall.

[A Case of Gastric Remnant Cancer after Proximal Gastrectomy with Jejunum Pouch Interposing Reconstruction].

A 83-year-old man was diagnosed an earlygastric remnant cancer on the site of jejuno-gastrostomyafter proximal gastrectomywith jejunum interposing reconstruction 23 years ago. A total gastrectomywas performed due to the difficultyof endoscopic submucosal resection. The surgical operation took 200 minutes and the blood loss was 180 mL.

[A Patient with Scirrhous Gastric Cancer Diagnosed and Resected Subsequently by Laparotomy Examination Due to Difficulty to Take Cancer Specimen by Endoscopic Biopsy].

Some of scirrhous gastric cancer are difficult to diagnose on the surface view or to take correct biopsy specimen.A 85-yearold man with dysphagia was diagnosed scirrhous gastric cancer endoscopically, but could not be taken a biopsy specimen showing cancer.We informed cases of scirrhous gastric cancer difficult to take correct biopsy specimen and recommended surgical operation to take correct specimen and to start a treatment.

[Successful Multidisciplinary Treatment of Metastatic Ovarian Cancer after Perforative Peritonitis of the Rectum Due to Disseminated Ovarian Cancer].

A72 -year-old woman who complained of abdominal pain and distention visited the emergency clinic of our hospital in April 2014. Computed tomography(CT)showed an omental mass and a pelvic mass with massive ascites. The fluid was removed by abdominal aspiration, and the patient showed perforative peritonitis next day.

The retroperitoneal interfascial planes: current overview and future perspectives.

Recently, the concept of interfascial planes has become the prevalent theory among radiologists for understanding the retroperitoneal anatomy, having replaced the classic tricompartmental theory. However, it is a little known fact that the concept remains incomplete and includes embryological errors, which have been revised on the basis of our microscopic study. We believe that the concept not only provides a much clearer understanding of the retroperitoneal anatomy, but it also allows further development for diagnosis and treatment of retroperitoneal injuries and diseases, should it become an accomplished theory.

Preliminary embryological study of the radiological concept of retroperitoneal interfascial planes: what are the interfascial planes?

Purpose: Recently, the radiological concept of retroperitoneal interfascial planes has been widely accepted to explain the extension of retroperitoneal pathologies. This study aimed to explore embryologically based corroborative evidence, which remains to be elucidated, for this concept.

Methods: Using serial or semi-serial transverse sections from 29 human fetuses at the 5th-25th week of fetal age, we microscopically observed the development of the retroperitoneal fasciae and other structures in the retroperitoneal connective tissue.
