A 49-year-old diabetic patient with abdominal pain was found at ultrasonography and computed tomography to have a cystic mass in the head of the pancreas with dilatation of the main pancreatic duct. The head of the pancreas and the duodenum were removed surgically. Examination of the operative specimen showed chronic pancreatitis, dilatation of the main pancreatic duct, and impacted mucus in the secondary ducts with villous proliferation of the ductal epithelium, thus allowing a diagnosis of intraductal adenomatosis. There was no evidence of malignancy. The resection margin was involved, and consequently the remainder of the pancreas was removed six months after the initial surgical procedure. A review of the literature showed that intraductal adenomatosis tends to spread and carries a high risk of malignant transformation. Surgery is required because of the risk of pancreatic duct obstruction and pancreatic cancer. Intraductal papillary tumour of the pancreas shares many characteristic with other adenomatous proliferation of the gastrointestinal tract (colorectal villous adenoma, bile duct adenomatosis) including the presence of villous structures with increased mucus production, a tendency to spread massively, and a high risk of malignant transformation.

A 47-year-old woman underwent endoscopic polypectomy of a villous adenoma in the lesser curvature of the gastric antrum. Shortly after the procedure, she complained of severe abdominal pain. An abdominal x-ray showed air under the diaphragm, suggestive of gastric perforation. On re-endoscopy, the cavity at the site of polypectomy was closed using endoscopically applied metallic clips. She was treated with intravenous hyperalimentation, omeprazole, and antibiotics for 10 days. Ingestion of food was started 10 days after admission, and she was discharged without any complaints. She is free of symptoms on follow-up after 8 months, and endoscopy showed complete healing of the perforation. The procedure is the third described for the stomach in the English literature and emphasizes the use of endoclipping in selected cases of small and well-defined perforations.

Enteroenteric intussusception is a condition in which full-thickness bowel wall becomes telescoped into the lumen of distal bowel. In adults, there is usually an abnormality acting as a lead point, usually a Meckels' diverticulum, a hamartoma or a tumour. Duodeno-duodenal intussusception is exceptionally rare because the retroperitoneal situation fixes the duodenal wall. The aim of this report is to describe the first published case of this condition. A patient with duodeno-duodenal intussusception secondary to an ampullary lesion is reported. A 66 year-old lady presented with intermittent abdominal pain, weight loss and anaemia. Ultrasound scanning showed dilated bile and pancreatic ducts. CT scanning revealed intussusception involving the full-thickness duodenal wall. The lead point was an ampullary villous adenoma. Congenital partial (type II) malrotation was found at operation and this abnormality permitted excessive mobility of the duodenal wall such that intussusception was possible. This condition can be diagnosed using enhanced CT. Intussusception can be complicated by bowel obstruction, ischaemia or bleeding, and therefore the underlying cause should be treated as soon as possible.

Alimentary tract duplications are rare congenital anomalies. They most often become symptomatic in childhood and rarely undergo malignant transformation. Pseudomyxoma peritonei (PMP) is an equally uncommon condition, most frequently originating from a primary appendiceal mucinous neoplasm. We report an extremely unusual case of PMP arising from an intestinal duplication. A 67-year-old woman presented with vague upper abdominal pain, and, unexpectedly, explorative laparoscopy revealed diffuse jelly-like peritoneal implants. The histopathological diagnosis of a low-grade PMP or "disseminated peritoneal adenomucinosis" was made. At that moment, no primary tumor was found. During later surgery, a cystic lesion located in the mesentery of the small bowel could be resected. Histologically, the cyst wall clearly showed the concentric layering of a normal bowel wall. The mucosa, however, displayed a diffuse low-grade villous adenoma. We concluded that this histological picture was most consistent with a small intestinal duplication, containing a low-grade villous adenoma. The adenoma caused a mucocele, which subsequently leaked or ruptured, giving rise to noninvasive mucinous peritoneal implants or low-grade PMP, also known as "disseminated peritoneal adenomucinosis" (DPAM).

Urachal carcinoma is an uncommon neoplasm. Benign urachal tumours are extremely rare. All urachal mucinous tumours, regardless of tumour type, have the potential to behave in an aggressive clinical manner that includes the development of pseudomyxoma peritonei. We report a 58-year-old man who presented with lower abdominal pain. Ultrasound and CT imaging defined a large lobulated cystic mass superior to the urinary bladder. At laparotomy, the multiloculated cystic mass, 10 x 8 x 6 cm, could be completely separated from the bladder and was excised. It was smooth-walled and filled with thick mucinous fluid. Histology revealed a complex mucinous cystadenoma of undetermined malignant potential of the urachus. The cystic spaces were lined by mucin-secreting columnar epithelium that showed focal areas of mild atypia. The epithelium lacked architectural features of villous adenoma. There was no stromal invasion to support an invasive neoplastic process. No pseudomyxoma peritonei was present. The patient was well, with no tumour recurrence, at 6 months follow-up.

An 81-year-old man with a history of villous adenoma of the duodenum was admitted with new-onset jaundice, abdominal pain, and pruritus, which raised concerns about disease progression and hepatobiliary obstruction. The patient had refused surgical resection of tumor on initial diagnosis 2 years earlier and opted out of it again at the current presentation because of his significant comorbidities. While discussing treatment options with his family, he developed symptoms suggesting myocardial infarction. Therefore, before anesthetizing this patient with escalating cardiac enzyme levels for an urgent noncardiac procedure, it was important to attend to the dynamics of the decision-making process.

Tubullo-villous adenoma of duodenum is a rare entity. These are potentially malignant tumours and therefore, complete excision is the treatment of choice. However, at times preoperative diagnosis could not be always achieved posing difficulty in choosing the optimal surgical method of excision. We report a 40-year-old male patient presented with vague upper abdominal pain and vomiting for last 6 months. His computed tomography and endoscopy demonstrated intraluminal polypoidal mass. Endoscopic biopsies were negative for malignancy. Local surgical excision with tumour free margin was performed and histology revealed tubullo-villous adenoma.

Giant tubular-villous adenoma of the rectum can determine secretory diarrhea, associated with a depleting syndrome of prerenal acute renal failure, hyponatremia, hypokalemia and hypoproteinemia. These symptoms are known as the McKittrick-Wheelock syndrome, and there are about 50 cases reported in literature. We present the case of a 59-year-old woman presented to our emergency department with abdominal pain, prerenal azotemia, and electrolyte disturbances with a background of chronic diarrhea, caused by a giant rectal tumor. Conservative therapy initially improved and normalized renal function, and made surgical resection of the tumor possible.
