[A Case of Double Colorectal Cancer Diagnosed by Preoperative CT Colonography].

A 66‒year‒old man was admitted to our hospital because of anemia and a positive fecal occult blood test in the medical examination. Colonoscopy revealed a type 2 advanced sigmoid colon cancer with circular stenosis. Computed tomography (CT)colonography was performed to examine the oral colon. The apple core signs were found both in the sigmoid and transverse colon. We diagnosed a double colon cancer and performed a laparoscopic left hemicolectomy and sigmoidectomy. The tumor was histopathologically diagnosed as a multiple cancer including a transverse and a sigmoid colon cancer. Although evaluations of the intestine for colon cancer with stenosis are performed by enema examination or endoscopic examination after colon stent placement, both examinations are invasive. CT colonography is considered to be a minimally invasive and an effective preoperative examination for colorectal cancer with stenosis.

Cervical chylous leakage following esophagectomy that was successfully treated by intranodal lipiodol lymphangiography: a case report.

BACKGROUND: Chylous leakage is a well-known complication after esophagectomy, but cervical chylous leakage is relatively rare, and considerable controversy remains regarding the appropriate management strategies. We herein report a case of cervical chylous leakage treated successfully by lipiodol lymphangiography. CASE PRESENTATION: The patient, a 70-year-old man with middle thoracic esophageal cancer, underwent radical esophagectomy with 3-field lymph node dissection and subsequently developed cervical chylous leakage. From the second postoperative day (POD2), the amount of fluid in the cervical drainage tube increased by 200-300 ml/day. We started octreotide (300 µg/day) on POD5 and etilefrine (120 mg/day) on the POD6. However, the amount of cervical discharge did not decrease. We performed lipiodol lymphangiography on POD8. Thereafter, the amount of cervical discharge finally began to decrease. We removed the drainage tube on POD13, and the patient was discharged from the hospital on POD23. CONCLUSIONS: Our case suggests the clinical efficacy of lipiodol lymphangiography for cervical chylous leakage after esophagectomy.

[A Patient with Recurrent Ulcerative Colitis-Associated Rectal Cancer Attaining a Complete Response with FOLFIRI plus Bevacizumab].

A 60-year-old man underwent laparoscopic total proctocolectomy with ileostomy for advanced ulcerative colitis-associated rectal cancer. The final diagnosis was advanced cancer pT3, pN2 and M0 (pStage Ⅲb). Adjuvant therapy with XELOX was performed. However, abdominal CT revealed a liver metastasis and lymph node metastases in the pelvis 6 months after surgery. The patient was treated with FOLFIRI plus bevacizumab. After 20 courses of chemotherapy, the patient was considered to have experienced a clinical CR, which has been maintained for 3 years 5 months.
