A 75-year old man was detected with a pediculate tumor in the upper esophagus. A biopsy determined that it was an adenocarcinoma. A subtotal esophagectomy with dissection of three-fields of lymph nodes was selected. The pathological study revealed it to be an esophageal adenocarcinoma arising from ectopic gastric mucosa of the fundus of the stomach. His(More)
PURPOSE The purpose of this study was to determine the most effective means of treating liver metastases from gastric cancer. METHODS We retrospectively examined 43 patients with liver metastases, but without peritoneal dissemination, who had received different forms of treatment. RESULTS The crude 5-year survival rates of patients who underwent(More)
BACKGROUND The clinical significance of lymph node involvement along the recurrent laryngeal nerves in cancer of the thoracic esophagus is still controversial. Although these lymph nodes are anatomically located in a well-defined compartment (proximal mesoesophagus), appropriate procedures for dissecting them are not well established. STUDY DESIGN We(More)
We report an unusual case of a large solitary fibrous tumor (SFT) in the retroperitoneum. A 53-year-old man was referred to our hospital for surgical treatment of a swelling in the right flank with dull pain. Abdominal computed tomography (CT) and echograms showed a large encapsulated tumor compressing the right kidney and liver. At laparotomy, the tumor(More)
KEY CLINICAL MESSAGE The present case involved a 62-year-old male with a large left-sided inguinoscrotal hernia. A CT scan and a clinical examination led to a diagnosis of a giant left-sided Amyand's hernia. The hernia was repaired using the ULTRAPRO Hernia System (UHS), and the patient exhibited an uneventful postoperative course.
Due to advanced gastric cancer with abdominal para-aortic lymph node metastases, we performed a curative operation in three cases in which S-1/CDDP combination therapy proved effective. In case 1, after only one course of this chemotherapy, the reduction of the primary lesion was slight, but para-aortic metastatic lymph nodes were remarkably reduced. We(More)
We examined the effect of activated lymphocytes stimulated with tumor-pulsed dendritic cells (DC-K), and found that such stimulation enhanced the cytotoxity of the activated lymphocytes. Furthermore, in applying DC-K to a recurrent case of esophageal cancer, the skin tumors disappeared after local injection of DC-K. The only adverse effect of this treatment(More)
A 71-year-old man suddenly developed abdominal pain and vomiting on drinking soda after a meal, and visited a physician. Cervical subcutaneous and mediastinal emphysemas were observed on CT, and the patient was transferred to the emergency medical center of our hospital on the same day. Esophagography was performed at our department. A ruptured region was(More)
We report the case of a 60-year-old woman with multiple lymph node metastases after ascending colon cancer who received radiation therapy and then chemotherapy with S-1. She was diagnosed with lymph node metastasis of the para aorta and left upper clavicle 10 months after surgery. We performed radiation therapy for the left upper clavicle (64 Gy)and para(More)
Even though liver resection is the first choice against metastatic liver tumors, oncologists are often obliged to include other treatment modalities depending on metastatic tumor size, number of metastatic nodules, location of tumors, patient's general condition, and so on. Among others we selected cryoablation therapy against unresectable tumors and(More)
