Currently, CT-E is not recommended as the first-line examination in patients when mucosal detail is required. Double-contrast barium air enteroclysis has advantages in demonstrating small mucosal abnormalities. The authors find CT-E of value in the work-up of patients with symptoms of intermittent small bowel obstruction, particularly those with a history of prior abdominal surgery; in the further work-up of selected patients with high-grade obstruction in whom general surgeons prefer initial conservative management (immediate postoperative small bowel obstruction, patients with history of prior abdominal surgery for malignant tumor, history of radiation treatment, and possible internal extraintestinal fistulae); in looking for complications of small bowel Crohn's disease; and in the patient with unexplained anemia or gastrointestinal bleeding. In a series of patients who had both abdominal CT and barium enteroclysis done, each examination provided unique and complimentary diagnostic information. Because CT-E combines the advantages of both methods of examination, is it the optimum imaging work-up in the investigation of small bowel disease? Further research and clinical experience will define the precise role of CT-E in the investigation of small bowel disease. Experience with this method of examination is limited to a few institutions, performed by investigators with interest in small bowel diseases. The addition of cross-sectional display and multiplanar reformatting made possible by multidetector-row helical CT to enteral volume change and the use of multifunctional nasointestinal catheters make CT-E an important tool in the investigation of small bowel disease. Experience has shown the increased reliability of any method of examining the small bowel that challenges intestinal wall distensibility by fluid enteral volume infusion.

Polyps occur throughout the gastrointestinal tract in Peutz-Jeghers syndrome, but the most serious problems are encountered in the management of small bowel polyposis. We report here on a case of Peutz-Jeghers syndrome admitted to hospital for intestinal obstruction and anaemia. The patient was submitted to colonoscopy, oesophagogastro-duodenoscopy and small bowel enema. At laparotomy, multiple intussusceptions were found and we conducted a combined surgical-endoscopic approach. Most of the polyps were identified and removed endoscopically (snare polypectomy). Five enterotomies were performed to remove 18 very large polyps (> 3 cm). Finally, a limited portion of the jejunal tract (20 cm) was resected owing to the presence of multiple, large, obstructive polyps. None of the polyps showed cancerous transformation. The shortcomings of the traditional surgical approach include repeated small bowel resections and often early reoperation to manage complications caused by polyps missed at the time of previous surgery. If surgical intervention is required, intraoperative endoscopy is always indicated. Conservative surgical management, the role of intraoperative endoscopy, planned medical follow-up and the need for a national registration system are stressed.

Helminths or worm infestations refer to worms that live as parasites in the human body and are a fundamental cause of disease associated with health and nutrition problems beyond gastrointestinal tract disturbances. Globally, over 3.5 billion people are infected with intestinal worms, of which 1.47 billion are with roundworm, 1.3 billion people with hookworm and 1.05 billion with whipworm. School children aged 5 - 15 years suffer the highest infection rate and worm burden that attributes to poor sanitation and hygiene. About 400 million school-age children are infected with roundworm, whipworm and hookworm worldwide, a large proportion of whom are found in the East Asia region (Cambodia, China, Lao PDR, Thailand and Vietnam). These parasites consume nutrients from children they infect, thus retarding their physical development. They destroy tissues and organs, cause abdominal pain, diarrhoea, intestinal obstruction, anaemia, ulcers and other health problems. All of these consequences of infection can slow cognitive development and thus impair learning. De-worming school children by anthelmintic drug treatment is a curative approach for expelling the heavy worm load. However, drug therapy alone is only a short-term measure of reducing worm infection and re-infection is frequent. Control measures through improved sanitation, hygiene and de-worming are needed to prevent infection and re-infection. UNICEF has supported many governments in this (and other) regions to assist in the provision of water supply and sanitary facilities and intensive hygiene education in many schools through the Water, Environment and Sanitation (WES) programme. The UNICEF supported school sanitation and hygiene education (SSHE) programme, and other programmes, could effectively enhance behaviour change in children to break the routes of worm transmission and other waterborne diseases.

A palliative combination chemotherapy regimen (FaFEC) was developed for patients with relapsed epithelial ovarian cancer in particular patients relapsing after, or ineligible to enter, phase II trials, usually due to lack of evaluable disease. Forty-six patients were enrolled. Patients had received a mean of 2.3 previous drug regimens and nine (19%) had intestinal obstruction at the start of FaFEC. The majority of patients were inevaluable by WHO criteria so objective response data was obtained from serial serum CA125 evaluations. A serological response was demonstrated in 8/44 (18%). The responders included 6/27 women who had a prior relapse-free interval of less than 3 months, four who were resistant to platinum chemotherapy and three patients who had previously received paclitaxel. The major (WHO grade 3/4) toxicities included leucopenia (six patients), anemia (three patients), thrombocytopenia (two patients), nausea and vomiting (four patients) and severe infections (five patients). Following FaFEC the median time to failure was 0.48 years and the median survival was 0.66 years. FaFEC was effective in this group of very poor prognosis patients. The serological response rate of 18% is noteworthy considering the multiple prior treatments that patients had received and the short treatment free intervals. FaFEC may be useful second line therapy in epithelial ovarian cancer patients ineligible for phase II studies and should be considered for a randomized comparison with paclitaxel.

Gastrointestinal metastasis from lung cancer is exceptional and generally asymptomatic. Other secondary localizations are often present. Metastastic dissemination may involve any portion of the gastrointestinal tract. Clinical expression is variable: dysphagia, anemia, bowel obstruction, peritonitis. Surgical treatment may be indicated in selected patients. We describe the cases of two patients who developed obstruction of the small bowel due to metastases from squamous-cell lung cancer. Bowel obstruction was in the inaugural sign in the first patient. Mesenteric metastasis was associated in the second patient.

Peutz-Jeghers syndrome is an autosomal dominantly inherited rare syndrome characterized by mucocutaneous pigmentations, with intestinal and extraintestinal polyps. It is accepted to be a precancerous syndrome. The polyps can cause anemia and intestinal obstruction and intussuception. We present a young patient admitted to our clinic with a history of recent gastrointestinal bleeding. Upper and lower gastrointestinal endoscopic examinations revealed multiple polyps located in the stomach, jejunum, rectum and terminal ileum. In addition, there were many mucocutaneous pigmentations on the lips, buccal mucosa and finger and toe nails. Jejunal polyps were found to be the cause of jejuno-jejunal invagination and iron deficiency anemia. Histopathological evaluation of the polyps revealed hamartomatous polyps of Peutz-Jeghers syndrome and this diagnosis was supported by a dermatology specialist. It is suggested that any patient presenting with ileus attacks and findings of anemia should be investigated for polyps and mucocutaneous pigmentations of the precancerous Peutz-Jeghers syndrome.

A 79-year-old female patient with rheumatoid arthritis treated with NSAIDs on long-term developed iron-deficiency anaemia and subsequently subacute intestinal obstruction. Barium enema showed multiple diaphragm-like strictures. At colonoscopy the lumen of the ascending colon was divided into compartments by multiple thin circumferential mucosal membranes. Right hemicolectomy was carried out. The histology of the resected specimen confirmed diaphragm disease of the large bowel. Diagnosis is usually difficult, even at laparotomy, due to the poor external presence of the disease. Such lesions are rare (about 10 cases have been reported in the world literature) and are similar to those previously described in the small bowel. With the increasing world-wide use of NSAIDs, clinicians must be aware of this rare gastrointestinal complication, which may require emergency surgical intervention.

Cavernous haemangioma of the small bowel is a vascular, benign and infrequent tumour, similar in both sexes and more typical from the third decade onwards. Its most common clinical manifestation is a chronic anaemia secondary to intestinal bleeding, other causes are intestinal obstruction and perforation. Preoperational diagnosis is difficult and the treatment of choice is surgical resection.

Ninety-eight patients with 100 different tumors of the small bowel were studied. There were more malignant than benign tumors. Adenocarcinoma was the commonest lesion and the ileum the most frequent anatomical site of all tumors. Except for carcinoid tumors, the lesions were observed more often in male than in female patients. The average age of patients in this series was higher than that reported in most other series. Loss of weight, and abdominal pain were the most constant symptoms. Clinical syndromes of anemia and bleeding, small bowel obstruction, biliary obstruction, perforation with peritonitis, abdominal tumor, melanosis with small bowel polyposis, and cutaneous von Recklinghausen's disease with small bowel neurofibromatosis were encountered either alone or in combination. In the group operated upon, a resection of the involved segment with end-to-end anastomosis was done when feasible. None of the patients operated upon before 1946 lived as much as five years after operation. The most common causes of death were extension of the primary tumor and metastasis, peritonitis due to perforation, associated bronchopneumonia, and hemorrhage.

About 20 per cent of patients with carcinoma of the colon or rectum present with metastatic disease. Surgeons are frequently asked to consider resection or other operative procedures in these patients for palliation. We performed this review to determine whether patients presenting with known metastatic colorectal cancer derive benefit from surgical intervention. We performed a retrospective review of all patients with M1 carcinoma of the colon or rectum who were identified from the University of Mississippi Medical Center Cancer Registry from April 1985 through February 2003. Patients who underwent hepatic and/or pulmonary resection with curative intent were excluded from analysis, as were patients with metachronous metastases. Eighty patients with M1 colorectal cancer who did not undergo surgery with curative intent were identified, and in 74 of these, complete medical records and follow-up were available. Forty-nine of the 74 patients (66%) underwent an operation, and 25 were managed nonoperatively. Indications for surgery included bowel obstruction, active hemorrhage, severe anemia from gastrointestinal bleeding with requirement for blood transfusions, intractable pain, and perforation of the colon. Average survival was 11.2 months for operative patients versus 6.5 months for nonoperative patients (P < 0.05). Thirty-six patients who underwent resectional procedures had a postoperative hospitalization of 7.5 days and a median survival of 11.5 months. Thirteen patients who had a nonresectional procedure had an average postoperative stay of 9 days and a median survival of 4 months. Median survival in those who did not undergo an operation was 4.8 months. Although metastatic colorectal carcinoma cannot usually be cured by surgical intervention, many patients who present with metastatic disease will benefit from palliative operations with relatively short hospitalizations and reasonable survival. Those who are not candidates for resection of the primary tumor have shorter survival times. Surgery can alleviate many of the distressing symptoms in patients with metastatic colorectal carcinoma.
