Pancreatic cancer remains a highly malignant disease. Curative treatment is only possible for patients diagnosed at a very early stage. Therefore, the vast majority of pancreatic cancer patients receive palliative treatment. Surgical palliation is offered to patients who are found not to have a resectable tumor. The treatment of obstructive jaundice is managed by stenting of the common bile duct or by a surgical bypass. The best possible surgical procedure should be based on the factors that influence hospital mortality, length of survival, and quality of life. In patients with a life expectancy of longer than 3 months, surgical bypass is recommended, with hepaticojejunostomy the treatment of choice. In the same surgical procedure, the relief of duodenal obstruction with a gastroenteric bypass should be achieved. Chemotherapy, radiotherapy, or a combination of both is employed as a neoadjuvant measure, as an adjuvant treatment, or, in most patients, as palliation. As palliative chemotherapy alone, 5-fluorouracil (5-FU) plus folinic acid is still the treatment of choice; however, newer drugs, such as gemcitabine, seem to have similar or marginally better results. Palliative radiochemotherapy with external-beam radiation plus 5-FU and folinic acid seems to lead to better local control of tumor progression but not to better survival, for which distant metastases are the limiting factor.

Progress in double-balloon endoscopy (DBE) has allowed for the diagnosis and treatment of disease in the postoperative bowel. For example, a short DBE, which has a 2.8 mm working channel and 152 cm working length, is useful for endoscopic retrograde cholangiopancreatography in bowel disease patients. However, afferent loop and Roux-limb obstruction, though rare, is caused by postoperative recurrence of biliary tract cancer with intractable complications. Most of the clinical findings involving these complications are relatively nonspecific and include abdominal pain, nausea, vomiting, fever, and obstructive jaundice. Treatments by surgery, percutaneous transhepatic biliary drainage, percutaneous enteral stent insertion, and endoscopic therapy have been reported. The general conditions of patients with these complications are poor due to cancer progression; therefore, a less invasive treatment is better. We report on the usefulness of metallic stent insertion using an overtube for afferent loop and Roux-limb obstruction caused by postoperative recurrence of biliary tract cancer under short DBE in two patients with complexly reconstructed intestines.

A 51-year-old woman who presented with a large cystic liver tumor with mural nodules in the lateral segment developed Trousseau's syndrome. A mural nodule directly invaded her liver parenchyma. Metastatic nodules were detected in the right lobe and portal/paraaortic lymph nodes. The pathological findings showed mucin-producing adenocarcinoma cells to have invaded the fibrous stroma forming a micropapillary cluster. She developed obstructive jaundice due to tumor progression and subsequently died of hepatic failure. Invasive biliary mucinous cystic neoplasm (MCN) is a rare form of a malignant tumor with a relatively favorable prognosis. This is a very rare case biliary MCN with invasive carcinoma that showed intrahepatic and lymph node metastases.
