The objectives of the study presented here were to evaluate the role of faecal stasis in the development of acute appendicitis. Inquiries about bowel habits were made of 188 patients admitted to this Department of Surgery with a clinical diagnosis of acute appendicitis, and of 188 healthy volunteers without known gastrointestinal disease, matched for age and sex. The results show that the number of bowel actions per week were significantly lower in the group of patients with acute appendicitis. Furthermore, the patients with a gangrenous and perforated appendix found at operation had significantly fewer bowel actions per week than those with phlegmonous appendicitis. These findings support the hypothesis of the importance of the obstruction of the appendix lumen in the development of acute appendicitis.

Because it may be difficult to evaluate gastrointestinal diseases in children with insulin-dependent diabetes mellitus (IDDM), this report highlights several clinical features unique to diabetes and emphasizes the relationship between gastrointestinal pathology and glycemic control. Two children with IDDM are described whose hyperglycemia, ketosis, and abdominal pain were the presenting features of H. pylori-positive duodenal ulcer disease and acute appendicitis, respectively. A third nondiabetic child developed persistent postprandial hyperglycemia as the initial manifestation of dumping syndrome. These patients illustrate the relationship between glycemic control and gastrointestinal pathology in children with diabetes and the effects of gastrointestinal dysfunction on glucose regulation in nondiabetic children. In children with IDDM, gastrointestinal pathology can be confused with ketoacidosis and complicate diabetes control and management. Early recognition and treatment of the underlying gastrointestinal disease often improves glycemic control. Furthermore, severe gastrointestinal dysfunction in nondiabetic children may deleteriously influence glycemic regulation and may be confused with childhood diabetes.

Appendicitis is the most common acute surgical emergency of childhood. Since the original report by Puylaert in 1986, the use of ultrasonography in the diagnosis of appendicitis has been the subject of considerable study. Among the reported diagnostic criteria, the maximal outer diameter (MOD) of the appendix is accepted as the one of the most reliable criteria used to differentiate between a normal appendix and acute appendicitis. However, MOD measurement is subject to inaccuracies because luminal distention by non-compressible, non-inflammatory material such as fecal material, or increased maximal mural thickness due to reactive mucosal lymphoid hyperplasia, or a medical cause due to a generalized gastrointestinal disease, such as Crohn's disease, can cause the measurement to exceed the upper limits of normality. The aim of this article is to introduce the spectrum of ultrasonographic findings in the normal and abnormal appendix and eventually to reduce unnecessary surgery in children.

Background. Visceral myopathy is rare pathological condition of gastrointestinal tract with uncertain clinical presentation and unknown etiology. It often presents with symptoms of chronic intestinal pseudoobstruction of colon. We report a case of visceral myopathy which presented to us as acute appendicitis and Ogilvie syndrome, and we managed it surgically. Method and Result. A case report of 20-year female clinically presented as acute appendicitis and we performed laparoscopic exploration which revealed inflamed appendix with grossly dilated ascending colon. We performed laparoscopic appendectomy and postoperatively managed the patients with IV fluids, antibiotics, neostigmine, and extended length rectal tube for enema and decompression. During postoperative period, she developed abdomen distension and peritonitis, and we ordered abdomen CT which revealed colon pseudo- obstruction. We performed right hemicolectomy with permanent ileostomy, and the histopathology reports of resected colon were visceral myopathy. Conclusion. Visceral myopathy is very rare group of disease and poorly understood condition that may present with chronic or acute intestinal pseudo-obstruction and often mimic other more common gastrointestinal disease. VM should be considered as differential diagnosis whenever the patient presents with acute appendicitis, uncharacteristic abdominal symptoms, recurrent attacks of abdominal distention, and pain with no radiological evidence of intestinal obstruction.

The failure to diagnose acute appendicitis (AA) is the third most common medical malpractice allegation related to gastrointestinal disease. There is a paucity of detailed data on this topic; however, publications by Whang et al and by Berlin and Berlin, which analyzed all types of malpractice suits against radiologists, have shown that the incidence of litigation has increased over time in the United States. This is likely true for cases of AA as well. The misinterpretation of cross-sectional imaging in patients with suspected appendicitis may be caused by suboptimal technique, errors of omission, i.e, missing key findings, failure to review a portion of the examination, and satisfaction of search error. This article summarizes the published legal, clinical, and imaging literature regarding litigation in cases of missed AA, and reviews optimized multidetector computed tomography and magnetic resonance imaging protocols for the diagnosis of AA, with examples shown of challenging cases.
