RESUMO
Circumportal pancreas (CP) is an extremely rare pancreatic fusion anomaly which is usually asymptomatic. This report presents the case of a patient with a tumor in the head of a CP and the retroportal accessory pancreatic duct in the pancreatic tissue behind the portal vein. A 53-year-old male was diagnosed with a nonfunctioning neuroendocrine tumor of the pancreas and resection of the tumor was scheduled. The patient was revealed to have CP on preoperative computed tomography and endoscopic retrograde cholangiopancreatography, which showed the pancreatic tissue encircling the portal vein and the retroportal accessory pancreatic duct. The patient safely underwent pylorus-preserving pancreatoduodenectomy reconstructed with pancreaticogastrostomy.
RESUMO
We report two cases of neuroendocrine carcinoma of the rectum. CASE 1: A 50s woman was diagnosed as rectal cancer and underwent anterior resection of the rectum and lymphnode dissection. The histological diagnosis was neuroendocrine carcinoma with peritoneal dissemination. She was treated with chemotherapy as an outpatient. One year later from the operation, multiple liver metastases were revealed and she died eight months later. CASE 2: A 50s man underwent endoscopic mucosal resection (EMR) of the rectum as rectal tumor and histological diagnosis was an early well-moderate deferenciated carcinoma and its cut-tend was unclear. He received a careful follow-up. One year later, a follow-up colonoscopy revealed a submucosal tumor in the lower rectum. He was diagnosised with local reccurence of rectal cancer, and then underwent an abdominoperineal resection of the rectum and lymphnode dissection. The histological diagnosis was poorly differenciated neuroendocrine carcinoma with lymphnode metastasis. Two months later from the operation, a local reccurence was revealed and he was treated with octreotide and irradiation.

A 60s male was admitted to our hospital for a diagnosis of gastric tumor sized 20 mm in diameter at the fornix of the stomach. Endoscopic mucosal resection (EMR) was performed, and the resected tumor was pap, m, ly0, v0, HMX, VM0, pathologically. One month after the EMR, the local recurrence was confirmed and a partial gastrectomy was performed. Pathological findings were tub1, sm2, ly1, v1, HM0, VM0. Total gastrectomy was added because of the possibility of the lymph node metastasis. Pathological findings revealed no residual cancers. The final pathological diagnosis was T1b(sm2) N0H0P0M0, Stage IA, based on the Japanese classification of gastric cancer. Three months thereafter, CT showed multiple liver metastases. Immunohistochemical study of the operated tumor revealed AFP-producing gastric cancer. Chemotherapy was performed, but he died of the gastric cancer. Endoscopic treatment is a minimally invasive therapeutic strategy, but it requires a considerable care in application.

We report a case of gastric metastasis of lung cancer performed gastrectomy for the primary foci. A 70s woman was diagnosed as having right lung cancer and underwent right lower lobectomy and lymph node dissection. The histological diagnosis was adenocarcinoma (pT4, N2, M0). Four years later, positron emission tomography (PET)-CT revealed a tumor in the stomach and para-aortic lymph nodes swelling. The submucosal tumor was showed in the cardia by endoscopic examination. Biopsy showed a papillary adenocarcinoma. With the diagnosis of gastric metastasis from lung cancer, she was operated on. A proximal gastrectomy was carried out. The histopathological examination demonstrated papillary adenocarcinoma similar to that of the lung cancer with lymph node metastasis. No postoperative complications occurred and she was discharged from the hospital. Since then, she was treated with adjuvant chemotherapy as an outpatient.

We report a case of multiple liver metastases of rectsigmoid colon cancer treated with systemic chemotherapy and hepatectomy. A 40s woman had undergone anterior resection of rectum for rectsigmoid colon cancer with multiple liver metastases. Then FOLFOX4 regimen was performed fifteen times, and FOLFIRI regimen was performed eleven times. After chemotherapy was enforced, an abdominal CT revealed that liver metastases were reduced in size (effect judgment of partial response). Hepatic resection of the right lobe and partial of S2 segment were performed. Pathological findings of the resected liver revealed no residual cancer cells, indicating that the histological effect of chemotherapy was complete response (CR).

The case was a 50s male with chief complaints of body weight loss and nausea. A clinical finding was Stage IV gastric cancer of poorly differentiated adenocarcinoma. We diagnosed it unresectable and started 5-FU+CDDP as the first-line chemotherapy. Partial response (PR) was observed and progression free time was 7 months. After 9 courses of 5-FU+ CDDP, the tumor grew and an oral intake was getting impossible. Gastro-jejunostomy was performed and then started a weekly PTX as the second-line chemotherapy after operation. The response was progressive disease (PD) after 4 courses of weekly PTX. Then we started S-1+CPT-11 as the third-line chemotherapy. We could continue S-1+CPT-11 for 9 courses without a severe adverse effect. Overall survival was 26.2 months.

UNLABELLED: The expandable metallic stent (EMS) have been used to treat obstructive colorectal cancer. We used EMS in 13 out of 14 cases of obstructive colorectal carcinoma patients (insertion rate 93%). Of these 13 cases, 6 cases were male patients, and 7 cases were female patients. The average age was 69.1-years-old (44-87). The placement of insertion part in rectum and sigmoid colon was 8 cases and 5 cases, respectively. We detained Ultraflex non-covered type for all patients. Seven patients were able to have an operation after stenting. After the stent treatment, 11 patients were able to eat, and 7 patients were discharged from hospital. COMPLICATIONS: perforation and stent migration were occurred in one case. These results suggested that EMS might be an effective treatment for obstructive colorectal carcinoma.

A 75-year-old man was referred to our hospital with a diagnosis of lower rectal cancer. Unstable angina attack occurred after admission and cardiac angiography revealed stenosis of three coronary arteries which were treated by percutaneous transluminal coronary angioplasty unsuccessfully. Coronary artery bypass graft was performed after colostomy. It is possible for operative stress, extracorporeal circulation and blood transfusion to diminish immunocompetence and increase the risk of recurrence. Therefore, CPT-11/5-FU/l-LV combination therapy (CPT-11 80 mg/m(2), 5-FU 500 mg/m(2), l-LV 250 mg/m(2) day 1, 8, 15 every 5 weeks) was carried out as neoadjuvant chemotherapy. The tumor decreased in size, and the level of tumor marker was normalized after two courses of the combination therapy. The patient is alive without recurrence three years after abdominoperineal resection.
