Coexistence of gastric cancer and gastric GIST with intra-tumor bleeding: successful embolization with subsequent total gastrectomy.

Background: Gastrointestinal stromal tumor (GIST) is a rare tumor, however, simultaneous development of gastric cancer and gastric GIST has been documented more frequently in recent years. Rupture of gastric GIST is even more rare and occurred in 7% of all GISTs. Although ruptured GIST might be occasionally difficult to be managed by endoscopy, transcatheter arterial embolization (TAE) was reported to control bleeding from GIST effectively.

[Findings from Total Colonoscopy in Obstructive Colorectal Cancer Patients Who Underwent Stent Placement as a Bridge to Surgery(BTS)].

We clinically investigated 34 patients with obstructive colorectal cancer who underwent placement of a colonic stent as a bridge to surgery(BTS), focusing on endoscopic findings after stent placement.Twenty -nine patients(85.3%)underwent colonoscopy after stent placement, and the entire large intestine could be observed in 28(96.

[Results of Preoperative Colon Stent Placement for Obstructive Colorectal Cancer].

We examined short-term outcomes in 34 patients who had stenting as a bridge to surgery(BTS)for obstructive colorectal cancer during the 5-year period between April 2012 and March 2017.T he patients were 22 men and 12 women with a mean age of 72.6 years.

[A Case of Retroperitoneal Liposarcoma That Required Three Times Surgical Resections during Four Years].

The patient was a 64-year-old man, who had undergone surgical resection for a right retroperitoneal giant tumor. The histopathological diagnosis was a well-differentiated liposarcoma. Two years and 4 months after the initial surgery, 3 recurrent lesions were found on the dorsal side of the colon hepatic flexure, and resection was performed.

[Cases of Obstructive Colon Cancer for Which Elective Surgery Was Performed after Colonic Stent Placement].

The present study investigated the short-term outcomes of 20 patients with obstructive colon cancer who underwent colonic stent placement as a bridge to surgery (BTS) during the 3-year period between April 2012 and March 2015. Subjects comprised 13 men and 7 women, with a mean age of 68.3 years.

[Case Report of a Splenic Abscess Due to Colon Cancer].

The patient was a 63-year-old man with a chief complaint of fever and abdominal pain. He was admitted with the diagnosis of splenic abscess on enhanced abdominal computed tomography. After improvement of general condition, we planned a colonoscopy.

[Stage IV Gastric Cancer Made Resectable Following a Chemotherapy Regimen That Included Trastuzumab-A Case Report].

A 70-year-old man was referred to our hospital after anemia was identified by his general practitioner. A detailed examination led to the diagnosis of unresectable StageIV gastric cancer with metastasis to the paraaortic lymph nodes. The cancer was HER2-positive; therefore, the patient was administered trastuzumab, capecitabine, and cisplatin combination therapy.

Inflammatory pseudotumour-like follicular dendritic cell tumour of the spleen.

We describe an unusual case of a 73-year-old woman presenting with a solitary splenic mass 8 cm in diameter and an elevation of serum soluble interleukin-2 receptor level. The preoperative diagnosis was primary malignant lymphoma of the spleen. Splenectomy was conducted.

[Study of S-1 and oxaliplatin(SOX) plus bevacizumab as first-line therapy in patients with unresectable colorectal cancer].

We examined the safety and efficacy of S-1 and oxaliplatin plus bevacizumab (SOX+BV)as first-line therapy for advanced/recurrent unresectable colorectal cancer. The subjects were 14 patients with colorectal cancer who received ≥3 courses of SOX+BV therapy in our department.The dosing regimen for 1 course was as follows: BV (7.

Laparoscopic partial hepatectomy of focal nodular hyperplasia.

Focal nodular hyperplasia is a benign liver lesion incidentally discovered with increasing frequency because of the proliferation of imaging studies. Radiographic characterization can diagnose this pathologic lesion and nonoperative therapy is the standard of care. However, surgical resection may be required for diagnostic reasons or symptomatic patients.

[A case of hilar bile duct cancer which recurred at abdominal and cervical lymph nodes 8 years after curative resection].

A 40-year-old man underwent right hemihepatectomy with biliary reconstruction for hilar bile duct cancer, and the surgical margin being negative. The tumor, showing atypical intraductal growth, was solid adenocarcinoma with rich mucinous component, although it was negative for MUC1, MUC2 and MUC5AC, suggesting that the tumor was not an intraductal papillary neoplasm of the bile duct (IPN-B). Eight years after operation, abdominal and cervical lymph node metastases were found on computed tomography and (18)F-deoxyglucose positron emission tomography examination.

Acute hemorrhagic colitis associated with oral administration of oseltamivir for the treatment of influenza A.

The importance of oseltamivir as a strategy for the treatment of influenza has been recognized; however, the risk of acute hemorrhagic colitis should be considered, although it is rare. This report describes a case of acute hemorrhagic colitis in a 61-year-old Japanese man after the oral administration of oseltamivir for influenza A. A definitive diagnosis of influenza A was made using a rapid diagnosis kit.

Left paraduodenal hernia successfully treated with laparoscopic surgery: a case report.

A 60-year-old Japanese man was referred for examination of abdominal pain. Abdominal MRI exactly demonstrated paraduodenal hernia. Propylthiouracil was administered until the patient became euthyroid, because Graves' disease was detected during the subsequent general examinations.

Hepatocellular carcinoma associated with autoimmune hepatitis.

Autoimmune hepatitis (AIH) is a disorder of unknown etiology, which often progresses to cirrhosis and carries a high mortality, even though its treatment with corticosteroids has become common. Hepatocellular carcinoma (HCC) has been reported as a rare complication of AIH. We describe herein a patient with HCC associated with AIH, in whom microwave coagulation therapy provided a means of definitive management, and we also review the literature.
