Villous tumors of the duodenum are rare, but treatment may be problematic because of their association with invasive adenocarcinoma. Two cases of villous tumor of the duodenum are described and 39 other reported cases are reviewed. Presenting symptoms were bleeding 27%; obstruction 24%; jaundice 22% and vague dyspepsia 20%. Diagnosis may be made by radiographic barium contrast evaluation of the duodenum, especially with the addition of air contrast hypotonic studies and by fibro-optic endoscopy. Twenty-seven per cent of villous tumors of the duodenum are associated with adenocarcinoma. Invasive tumor is more common in patients over 50 years old (35%), in tumors of the third and fourth portions of the duodenum (44%) and in tumors over 4 cm in diameter (30%). Local excision is the treatment of choice for benign lesions. Pancreatico-duodenectomy is recommended for tumors which include invasive carcinoma in patients without distal metastases.

The total gastrectomy, as known can expose to some sequences which form on a pathophysiologic and clinic plain syndrome of "AGASTRIC". The most paradigmatic of these disturbances are the weight loss, the pain, the dyspepsia, the anorexia, can be erroneously interpreted as a recurrence of the neoplasm illness. On the base of these disturbances, there are some pathophysiological alterations associated to the resection. The postprandial distension syndrome, the dumping, the diarrhea, the anemia, can be relieved by an appropriated hygienic-diet therapy. The reflux of biliopancreatic secretion into the esophagus, the disturbances related to the duodenal exclusion, the accelerated transit can be loosed or reduced by a correct technic, while the cloridopeptic deficiency is obviously unresolvable. From 1981 till 1988, 43 patients were submitted to a total gastrectomy for adenocarcinoma (29 M, 14 F), having a middle age of 62 years: 30 with a radical intent (Ro), and 13 palliative. Besides 10 of the Ro group were submitted to a enlarged intervention. The digestive continuity was renewed through an interposition of isoperistaltic jejunal loop according Mouchet-Camey in 23 cases, by use of a dysfunctional loop according Roux en-Y in 5, and by esophagus-jejunal T-L anastomosis such omega, according Horloff in 2 cases. There were registered one decrease for A.R.D.S. All the patients were been followed according the follow-up protocol, for monitoring neoplasm evolution of the illness and the eventual metabolic-functional disturbances. In the periodic postoperative control all the patients with Mouchet-Camey reconstruction had no evidenced dumping syndrome, neither cases of malabsorption of the essential nutritive principles, with constant recover of the weight.(ABSTRACT TRUNCATED AT 250 WORDS)

Nineteen patients with colorectal adenocarcinoma, three with cholangiocarcinoma, two with hepatocellular carcinoma, and one with carcinoid were treated with hepatic artery infusion chemotherapy. An implantable pump system was used to deliver floxuridine (FUdR), starting at 400 mg for 2 weeks with 2 weeks of rest. Eleven of 15 (73%) measurable patients with colorectal carcinoma responded. Of 6 complete responses, 4 were documented by laparotomy, including 1 with cholangiocarcinoma. Toxicity included dyspepsia and elevated liver function tests in all patients, gastric ulcer in 2, cholecystitis in 2, and sclerosing cholangitis in 3. Overall median survival for the colon cancer patients has not been reached at 16 months. Regional disease was controlled in the majority of patients treated with this regimen with acceptable toxicity and good quality of life.

Although the SAC generally are healthy and tolerant of a wide variety of management schemes, a number of noninfectious diseases have been documented to occur, affecting all body systems. Gastrointestinal diseases appear to be the most common afflictions, particularly dental diseases, indigestion, ulceration of the third compartment, and the various causes of colic, such as enteritis, peritonitis, and intestinal accidents. Diseases of the urinary system (urolithiasis, amyloidosis, and glomerulonephritis in particular), the nervous system (especially various compressive lesions of the spinal cord), and the respiratory system (such as obstructive pulmonary diseases) are not uncommon. Diseases of the cardiovascular system (other than congenital defects), hemolymphatic system, and nonsurgical diseases of the musculoskeletal system only rarely are encountered. Heat stress appears to be a very common problem in certain areas, but other metabolic diseases (ketosis, hypocalcemia, and hypothyroidism) are of minor importance. It is assumed that SAC are susceptible to most of the same toxicities that affect domestic livestock species. The best documented examples appear to be the Ericaceae family of plants (laurels, rhododendrons, and so on) and the organophosphate chlorpyrifos. Neoplasia occasionally is seen; examples include lymphosarcoma, gastric squamous cell carcinoma, and adenocarcinoma. As the longevity of these species increases because of their pet status, neoplasia can be expected to become more common. The treatment of most of these conditions is based upon extrapolation from domestic ruminants.

One hundred and sixty-seven patients in a single general practice who presented with ulcer-like dyspepsia were offered an upper gastrointestinal fibre endoscopy. Twenty-two patients had a peptic ulcer while only three had a gastric ulcer. One patient had a carcinoma of the cardia, one an adenocarcinoma in the body of the stomach and one a carcinoma at the ampulla of Vater. In another 55 patients the main findings at endoscopy were edema/reddening or erosions in the antral or duodenal mucosa. Endoscopic findings were normal in 46 patients. Malignancies were found only in patients over 50 years of age and only 4 ulcers were seen in patients under 40. The clinical findings of presence of night pain, pain relief after food intake and history of peptic ulcer were more common in patients with an existing peptic ulcer than in those with a normal endoscopy.

In a 48 year old man suffering from dyspepsia and progressive enlargement of the liver, the clinical suspicion of a malignant cystic disease of the liver was voiced. Six months after the onset of the complaints the disease was diagnosed through a biopsy performed during an operative laporotomy. The patient died in spite of combined antitumorous chemotherapy in some further 7 months in a state of hepatic coma. A detailed pathologico-anatomical examination divulged the picture of a very rare form of carcinoma arising from the membrane covering not only the hepatic cysts but also those in the kidneys. Microscopically it had the structure of a papillary adenocarcinoma. Differential diagnostic variations of this tumour as compared to true neoplastic cysts i. e. cystadenomas or cystadenocarcinomas arising from the lining of hepatic bile ducts, are pointed out in this paper.

High-dose thymidine (dThd) was given to 12 patients with advanced hematological and solid tumors. The dose schedule used was 75 g/sq m/day, given i.v. continuously for 5 days or more. Myelosuppression, especially leukopenia, was the dose-limiting toxicity. Nonhematological toxicities affected the gastrointestinal tract (nausea, vomiting, anorexia, diarrhea, and indigestion) and the central nervous system (somnolence, headache, visual illusions, and memory impairment). Patients who had received cumulative doses of dThd developed alopecia. Thymine crystals were noted in the urine after refrigeration. Tumor regression (less than partial remission) occurred in one patient with melanoma. Three of four patients with acute leukemia had a fall in peripheral white blood cell counts and blasts but no marrow improvement. Four patients with adenocarcinoma (three colon, one unknown primary) had stable disease. Pharmacokinetic studies revealed that, at a dThd dose of 75 g/sq m/day, millimolar concentrations of dThd and thymine can be achieved in the plasma. The half-life of dThd was approximately 100 min. One-third of the plasma concentrations was measurable in the cerebrospinal fluid. dThd was mainly excreted by the kidneys.

The extent to which the different resections relieve the symptoms of gastric cancer is poorly defined. The symptoms of 57 consecutive patients undergoing standard resection of gastric adenocarcinoma by oesophagogastrectomy (n = 19), total gastrectomy [16] or partial gastrectomy [22] were studied prospectively. Common symptoms were relieved in 80% of cases and this was independent of tumour stage. Symptoms were significantly more frequent after total gastrectomy than after partial gastrectomy or oesophagogastrectomy, the difference being attributable principally to the development of new symptoms after total gastrectomy. While abdominal pain, nausea and vomiting were largely relieved by resection, dyspepsia or dysphagia worsened in 31% of patients following surgery, especially total gastrectomy (P < 0.05). Resection relieves the symptoms of gastric cancer adequately but outcome is influenced by operation type. As total gastrectomy gives a poorer symptomatic outcome, it should be avoided when the performance of an alternative procedure does not compromise established principles of resection.

Long-term infection with Helicobacter pylori could potentially lead to asymptomatic chronic gastritis, chronic dyspepsia, duodenal ulcer disease, gastric ulcer disease, or gastric malignancy, including both adenocarcinoma and B-cell lymphoma. Currently, the two most important indications for eradication of this bacterium are proven H. pylori-associated duodenal or gastric ulcer disease. Many studies have shown that successful eradication of H. pylori dramatically reduces the rate of duodenal ulcer relapse, and long-term follow-up data appear to support the claim 'no H. pylori, no gastritis; no gastritis, no ulcer', which follows on from the old, but certainly valid, dictum 'no acid, no ulcer'. Furthermore, absence of relapse parallels the marked improvement in gastric histology (e.g. regression of gastritis). Whether there is concomitant regression of gastric metaplasia in the duodenal bulb is, however, controversial. Despite the rather limited data for H. pylori-associated gastric ulcer, successful eradication of the organism has been equated with cure of peptic ulcer disease. Again, eradication parallels a substantial improvement in gastric histology. Although eradication of H. pylori is not currently recommended in asymptomatic individuals or dyspeptics, it has been well documented in previous studies that successful eradication improves the gastric histology in patients with H. pylori-associated dyspepsia. From these studies, it appears that the disappearance of polymorphs from the inflammatory infiltrate occurs rather rapidly after eradication, although regression of the mononuclear component of the inflammatory reaction is more prolonged.

To investigate Helicobacter pylori (H. pylori) infection in subjects with and without gastroduodenal diseases in Taiwan, IgG antibodies to H. pylori were examined in 136 healthy volunteers, 101 patients with non-ulcer dyspepsia, 122 gastric ulcers, 119 duodenal ulcers, and 161 gastric adenocarcinomas. The seropositivity was highest in duodenal ulcers (87.4%) (p < 0.001, as compared to healthy volunteers), followed by gastric ulcers (76.2%) (p < 0.01, as compared to healthy volunteers), but similar among gastric adenocarcinomas (60.3%), healthy volunteers (58.8%), and patients with non-ulcer dyspepsia (55.5%). Higher acquisition of H. pylori in younger patients with duodenal and gastric ulcers suggests a strong association with H. pylori. No ulcer characteristics, including number, location, and activity, were significantly statistically associated with the seropositivity of H. pylori in gastric and duodenal ulcers. Similarly, the location, extent of invasion, and histology of gastric adenocarcinoma was not significantly statistically associated with the seropositivity of H. pylori.
