Adenomyoma is a rare benign lesion occurring commonly in the fundus of the gallbladder in the biliary tract. Ampullary adenomyoma is rarer still, presenting as obstructive jaundice due to its location at the ampulla and may mimic malignancy on clinical and radiological examination. Endoscopic biopsy may not be always diagnostic if the lesion is deep seated. Histologically these lesions show a c...

Endoscopic retrograde cholangiopancreatography with endoscopic sphincterotomy is a well-established procedure for the treatment of bile duct strictures. However, the procedure is difficult to perform in patients with intradiverticular papillae or tumor infiltration of the major papilla. Percutaneous transhepatic biliary stenting (PTBS) is commonly used in the management of malignant biliary str...

Gardner's syndrome is characterized by colonic polyps, osteomas of the skull and the mandible, and soft tissue tumors. Patients with this syndrome can also develop extracolonic manifestations such as periampullary tumors and desmoid tumor of the abdomen. We report a 36 year-old female with Gardner's syndrome and recurrent desmoid tumors of the abdomen, presenting with fever and malaise for 2 da...

The results of operations on 129 cases of periampullary carcinoma performed in our department during the period from January 1969 to June 1983 were studied. The rates of resection in ampullary carcinoma and inferior bile duct carcinoma were high, while the rate in pancreas head carcinoma was low. The operative mortality in resected cases was as low as 4. 3%. The number of longer survival for ov...

Sperti, C., Pasquali, C., Piccoli, A., Sernagiotto, C. andPedrazzoli, S. (1994) Radicalresectionfor ampullary carcinoma." long-term results. British Journal ofSurgery, 81: 668-671. Of 36 patients with carcinoma of the ampulla of Vater who underwent surgery between 1971 and 1990, 31 had a radical operation. There was one operative death. The overall 5and 10-year survival rates were 56 and 37 per...

The efficacy of lung metastasectomy is well established in several cancers, including colorectal cancer. However, little is known about the result of lung metastasectomy in carcinoma of the ampulla of Vater. Only two case reports have reported the efficacy of metastasectomy in ampullary cancer patients with pulmonary metastasis. We report the result of bilateral lung metastasectomy in a patient...

Duodenal gangliocytic paraganglioma (DGP) is a rare tumor that characteristically occurs in the second part of duodenum. These appear as submucosal masses that protrude into the lumen of a duodenum. Gastrointestinal bleeding is the commonest manifestation of DGP. Metastatic spread to regional lymph nodes occurs rarely. Surgical resection is the treatment of choice for DGP. A case of a DGP is re...

Familial adenomatous polyposis is an archetypal disease illustrating the genetic basis of human cancer. The adenomatous polyposis coli gene functions as a tumor suppressor with hundreds of known mutations that result in a defective adenomatous polyposis coli protein. In addition to the certain fate of colon cancer without colectomy, patients with familial adenomatous polyposis are also at incre...

To reveal patterns of input from the six semicircular canals to motoneurons of various neck muscles and their relationship to the mechanical actions of individual neck muscles, patterns of input to neck motoneurons of the longissimus and the semispinalis muscle groups were investigated in the upper cervical spinal cord of anesthetized cats. Intracellular potentials were recorded from motoneuron...
