A 69-year-old woman was admitted with facial flushing, weight loss and intermittent diarrhoea. Urinary 5-hydroxyindole-acetic acid (5-HIAA) level was elevated at 200 micromol/24 h (normal: < 50). Computerized tomography (CT) demonstrated multiple enhancing liver metastases with biopsy proven carcinoid metastases with no evidence of primary tumour at this stage. Octreotide was initiated, resulting in marked improvement in carcinoid symptoms. Nine years later, she presented with abdominal pain and slightly deranged liver function tests. Repeat colonoscopy at this stage, showed an ileal tumour causing impending obstruction, necessitating urgent right hemicolectomy. Histology demonstrated primary carcinoid tumour. She continued on octreotide. Three years later at the age of 81 years, she suffered a fatal haemorrhagic stroke. Autopsy revealed complete regression of hepatic carcinoid metastases.

We have evaluated survival and tumor-related symptoms in the presence of mesenteric lymph node and liver metastases in relation to surgical procedures in 314 patients (148 women, mean age at diagnosis 61 years; 249 with liver metastases) treated for midgut carcinoid tumors. Of the operated patients, 46% presented with severe abdominal pain and intestinal obstruction and were operated on before the diagnosis. Medical treatment (somatostatin analogs, interferon-a) was initiated in 67% and 86%, respectively. Surgical attempts included small intestine or ileocecal/right-sided colon resection with excision of mesenteric lymph node metastases. Most of the patients (n = 286) had mesenteric lymph node metastases; 33% of them had unresectable mesenteric lymph node metastases and underwent surgery without mesenteric dissection. Patients who underwent resection for the primary tumor had a longer survival than those with no resection (median survival 7.4 vs. 4.0 years; p <0.01). Patients who underwent successful excision of mesenteric metastases had a significantly longer survival than those with remaining lymph node metastases. Patients operated on for a primary tumor but with remaining lymph nodes but no liver metastases and who subsequently received interferon and somatostatin analog treatment had a median survival of 7.4 years. Resection of the primary tumor and the mesenteric lymph node metastases led to a significant reduction in tumor-related symptoms. Surgery to remove the primary intestinal tumor including mesenteric lymph node metastases is supported by the present results, even in the presence of liver metastases. Liver metastases and significant preoperative weight loss are identified as major negative prognostic factors for survival.

An 86-year-old woman was admitted because of right lower abdominal pain. A 7 by 6 cm tumor palpable in the right lower quadrant was poorly mobile. Abdominal CT scan showed a huge tumor with a strong enhancement effect. Barium enema and colonoscopic examination revealed a submucosal tumor located from the cecum to the ascending colon on the oral side. An undifferentiated adenocarcinoma was suspected after examination of the biopsy specimen, right hemicolectomy was performed. The tumor invaded the retroperitoneal membrane. Histological examination showed a very atypical carcinoid tumor with central necrosis invading the veins. Pathohistologically, the huge tumor was diagnosed as endocrine cell carcinoma or atypical carcinoid. Furthermore, an elevated lesion, 2.5 cm in size, was revealed in the cecum closed to the huge tumor. Histological examination showed that the polypoid lesion was early moderately differentiated adenocarcinoma. There was no transition between the two tumors. The patient was discharged, but died of local recurrence 9 months after the surgery. Endocrine cell carcinoma of the large bowel is rare, in particular of the ileocecal region. Endocrine cell carcinoma of the ileocecal region adjacent to an adenocarcinoma without transition had not been reported previously in Japan.

Flushing is a known symptom in intestinal carcinoid tumors which usually occurs only in the presence of liver metastases. A 62-year-old women presented with abdominal pain, nausea and flush symptoms. US, CT, octreotide scintigraphy and biopsy revealed a primary mesenteric carcinoid with retroperitoneal lymph node metastases and a solitary leftsided supraclavicular lymph node metastasis proving lymphatic spread over the thoracic duct, but liver metastases were excluded. This is a report on a mesenteric carcinoid which lead to flush symptoms despite absence of liver metastases, since retroperitoneal lymph node metastases enabled a direct hormone release into the systemic circulation.

We report a case of primary liver carcinoid. A 50-year-old woman had undergone left nephrectomy six years earlier for renal cell carcinoma. She developed abdominal pain. CT scans showed a low-density area in the lateral segment of the liver and lymph node swelling to the left of the abdominal aorta. Angiography showed a hypovascular tumor. After lateral segmentectomy and examination of the gastrointestinal tract, we diagnosed primary liver carcinoid. Unfortunately, the tumor recurred at multiple sites in the residual liver about 9 months after the first operation. She underwent further liver resection and microwave coagulation therapy. At that time, lymph node biopsy confirmed metastatic carcinoid. We began hepatic arterial chemotherapy for the residual liver and radiation therapy for the para-aortic lymph nodes (total 45 Gy). During chemotherapy, no recurrence was seen. At 11 months after reoperation, however, multiple liver metastases occurred with severe liver dysfunction and jaundice. She died about 24 months after the first liver resection.

Chronic pelvic pain is common in women of reproductive age and accounts for more than 40% of all laparoscopic procedures. In up to 40% of these patients laparoscopic findings are negative. As a result, many gynecologists frequently excise portions of the uterosacral ligaments and biopsy inconspicuous pelvic lesions in an effort to perform uterosacral nerve ablation and also to identify subclinical endometriosis. During diagnostic laparoscopy for chronic intermittent pelvic and abdominal pain, a 37-year-old woman was noted to have an incidental, 5-mm, pink-white nodule in the right uterosacral ligament. Pathologic examination reported features typical of a carcinoid tumor. Further evaluation by computerized tomographic scan and indium-III octreotide scan identified a 1.6-cm lesion in the mesentery. At laparotomy a 2-cm primary mucosal tumor in the terminal ileum and a 2-cm nodule in the adjacent mesentery were present. Carcinoid tumor was confirmed in 2 nodules and in 7 of 17 mesenteric lymph nodes. Liver and lung metastases were not seen.

Functioning gastroenteropancreatic endocrine tumors produce and secrete different substances that can be detected in the plasma and cause hormone-related syndromes. Symptoms such as diarrhea associated either with typical skin rash or peptic ulcer disease may be suggestive of the presence of intestinal carcinoid or gastrinoma. Other clinical manifestations such as severe hypoglycemia, diabetes, necrolytic erythema and gallbladder disease may also indicate an endocrine tumor. Sometimes, patients present no, or just vague, symptoms such as dyspepsia or abdominal pain and nonfunctioning endocrine tumors in these patients can be found incidentally during diagnostic imaging procedures or at operation. Usually, the diagnosis is established by the measurement of the specific tumor marker in the plasma and, sometimes, in the urine. In some cases, normal basal hormone levels are observed even in the presence of typical symptoms. Therefore, stimulatory tests such as the secretin test for gastrinomas are required to establish the diagnosis. General markers for the diagnosis of gastroenteropancreatic endocrine tumors are also available. Among these, chromogranin A has proved to be of great value for diagnosing nonfunctioning tumors and is considered the most sensitive general marker. The availability of both specific and general markers as well as stimulatory tests may enable the clinician to diagnose functioning gastroenteropancreatic endocrine tumors at an early stage and to recognize nonfunctioning tumors.

Twenty-seven primary small bowel tumours encountered at the University of Alberta Hospital in a 10-year period have been reviewed. Seventeen symptomatic growths were treated by resection and 10 asymptomatic tumours were discovered incidentally. During this same period, three intramesenteric lipomas were found. Small bowel tumours were malignant in 15 of the 17 symptomatic cases and benign in seven of the nine asymptomatic cases. Carcinoid tumours, malignant lymphomas, non-lymphoid sarcomas and carcinomas were the common malignant neoplasms while adenomas, lipomas, myomas, fibromas and angiomas comprised the majority of benign growths reported. Symptoms of anorexia, anemia, abdominal pain, obstruction and hemorrhage suggest small bowel tumour if commoner pathology has been ruled out.

Tumors of the small bowel, both benign and malignant, are relatively uncommon. As the symptoms are vague and conventional diagnostic tests are unsatisfactory, these tumors often present a clinical, radiological, and endoscopic challenge. We report here on five patients in whom small-bowel tumors were diagnosed using wireless capsule endoscopy. The indications for capsule endoscopy were: obscure gastrointestinal bleeding in four patients (one jejunal capillary hemangioma, one ileal hemangiosarcoma, and two jejunal gastrointestinal stromal tumors) and chronic abdominal pain in one patient (ileal carcinoid). Wireless capsule endoscopy, a new endoscopic method, promises to improve the diagnosis of deep small-bowel pathology.

Carcinoid tumors are rare forms of gastrointestinal tumors, although lately they have been found with increasing frequency. We report here the combined diagnosis of an intestinal metastasized carcinoid tumor. A 67-year-old patient was followed up during a nine-year period. In 1990 the patient was diagnosed with carcinoid tumor of intestinal origin with multiple liver metastases. Initial treatment consisted of partial resection of the intestine and resection of the liver. Since multiple liver metastases were found, chemoembolization was also performed. After this therapy the patient was free of complaints until 1996. That year the patient reported upper abdominal pain with occasional diarrhea. Given his past medical history and multiple hepatic metastases proven by three-dimensional ultrasonography, combined octreotide and interferon therapy was started following octreoscan scintigraphy. During a three-year period the patient was without complaints and the tumor marker value decreased to almost normal. In 1998 the patient at a regular follow-up visit complained about colic abdominal pain around the umbilical region. Abdominal ultrasonography showed a local wall thickening in the intestinal region. The computed tomography and selective enterography were positive as well. The surgical treatment and histology demonstrated intestinal recurrence of the tumor in the ileal region. After the operation we started a long-acting sandostatin and interferon treatment. We conclude that an ultrasound with a high index of clinical suspicion is a useful test for the diagnosis of carcinoid tumor in detection and in follow-up examinations.
