[A Case in Which Inferior Vena Cava Stent Placement Was Effective for Inferior Vena Cava Stenosis Due to Metastatic Liver Tumor].

A 60s woman was diagnosed with cecal cancer with multiple liver metastases(final pathology was T4aN1M1[H1])and underwent ileocecal resection and D3 dissection. She did not wish for postoperative chemotherapy and surgical treatment of liver metastases. One and a half years after surgery, she developed extremity edema of lower legs and hypoalbuminemia, and she gained 20 kg. Contrast-enhanced CT showed stenosis of the inferior vena cava due to liver metastases, which was markedly improved the symptoms by placement of an inferior vena cava stent. Inferior vena cava stent placement is a minimally invasive treatment and can be an option as it can be expected to improve quality of life in some cases.

A case of gastric and duodenal mucosa-associated lymphoid tissue lymphoma with multiple gastric cancers: a case report.

BACKGROUND: Gastric mucosa-associated lymphoid tissue (MALT) lymphoma is often caused by Helicobacter pylori and has a good prognosis. Rarely, patients with MALT lymphoma may have gastric cancer and have a poor prognosis. CASE PRESENTATION: We herein report a case in which surgical treatment was achieved for a 72-year-old male patient with gastric and duodenal MALT lymphoma coexisting multiple gastric cancers. He underwent upper endoscopy for epigastric discomfort, which revealed mucosal erosion on the posterior wall of the middle body of the stomach, an elevated lesion on the duodenal bulb, and a raised tumor on the antrum of the stomach. He was diagnosed with gastric and duodenal MALT lymphoma with early gastric cancer. One month after H. pylori eradication, a second upper endoscopy revealed no improvement in the gastric or duodenal mucosa, and areas of strong redness with a shallow recess just below the cardia of the stomach. As a result, a diagnosis of gastric and duodenal MALT lymphoma with two gastric cancers was made. Total gastrectomy with proximal duodenum resection using intraoperative upper endoscopy and regional lymph node dissection was performed. Pathologically, gastric and duodenal MALT lymphoma and three gastric cancers were detected. Since one of them was an advanced cancer, he started taking S-1 after his general condition improved. CONCLUSION: For early detection of gastric and duodenal MALT lymphoma or gastric cancer, appropriate upper endoscopy and a biopsy are important. It is necessary to select a suitable treatment, such as H. pylori eradication, endoscopic treatment, surgery, chemotherapy, and irradiation, according to the disease state.
