Appendectomy for suspected appendicitis cases is a common procedure. Its clinical diagnosis needs to be supported by accurate confirmatory tests. No single paraclinical test with a high degree of sensitivity and specificity is available for its diagnosis. The appendix contains numerous serotonin-producing cells (enterochromaffin cells). In the inflammatory process and subsequent cell injury, serotonin is released and converted to 5-HIAA (5-hydroxy indole acetic acid). We studied the elevation of 5-HIAA in the spot urine of acute appendicitis patients. ⋯ We have concluded that measurement of 5-HIAA in spot urine is a highly reliable test supporting the clinical diagnosis of appendicitis and if it does not show an increase, appendicitis can be ruled out with a very high degree of confidence which helps to reduce unnecessary appendectomies. In clinically suspected appendicitis patients with diarrhea, an increase of 5-HIAA may not confirm the diagnosis.

Splenic arterial ligation prevents liver injury after a major hepatectomy by a reduction of surplus portal hypertension in hepatocellular carcinoma patients with cirrhosis.
In this study, we investigated whether a reduction of surplus portal hypertension after a major hepatectomy by SPL (splenic arterial ligation) prevents a liver injury in cirrhotic patients with hepatocellular carcinoma. ⋯ The decompression of surplus portal hypertension by SPL might be effective in the prevention of post hepatectomized liver injury and the improvement of postoperative mortality and morbidity.

Randomized Controlled Trial Clinical TrialIs there any relationship between functional dyspepsia and chronic gastritis associated with Helicobacter pylori infection?
The relationship between functional dyspepsia, H. pylori infection and chronic gastritis is controversial. Our aims were 1) To determine the prevalence of symptoms and the degree of association between symptoms and histopathological findings in different topographical gastric regions in patients with functional dyspepsia and H. pylori infection; 2) To determine the effect of eradication treatment on functional dyspepsia symptoms. ⋯ Advanced morphological changes of gastric mucosa were found to be significantly associated with symptoms of dysmotility. Pain on an empty stomach is predictive of antral inflammation. Cardia showed higher values of mean association with symptoms 6 months after therapy. Eradication treatment results in an improvement of both inflammatory changes and symptoms. In some patients persisting dysmotility symptoms were associated with persistent inflammation in cardia, which was also true for antrum, however to a lesser degree.

Case ReportsIntestinal Behçet's disease associated with myelodysplastic syndrome with chromosomal trisomy 8--a report of two cases and a review of the literature.
Two cases of intestinal Behçet's disease, which developed in the state of myelodysplastic syndrome with trisomy 8, are presented. Both cases are included in the incomplete type of Behçet's disease, with recurrent aphthous stomatitis, skin lesions, genital ulcers or vascular involvement and punched-out ulcers in the cecum, without ocular involvement. ⋯ Their histories indicated that myelodysplastic syndrome might have started before the development of intestinal Beçet's disease. Theses findings suggested that chromosomal trisomy 8 might play an important role in the pathogenesis, at least in some groups, of intestinal Behçet's disease.

Practical guidelines for the preservation of the pancreaticoduodenal arteries during duodenum-preserving resection of the head of the pancreas: clinical experience and a study using resected specimens from pancreaticoduodenectomy.
The purpose of this study was to create a practical guideline for vascular preservation during duodenum-preserving resection of the head of the pancreas. ⋯ To safely perform duodenum-preserving resection of the head of the pancreas, preservation of the whole posterior pancreaticoduodenal artery and anterior inferior pancreaticoduodenal artery is recommended because they can be safely dissected from the pancreas, and the posterior pancreaticoduodenal artery provides the major blood supply to the papilla and distal bile duct. However, removal of a short segment of posterior pancreaticoduodenal artery does not preclude a good blood supply to the duodenum because of bidirectional blood flow.
