The syndrome of mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS) is an uncommon neuromuscular disorder caused by mitochondrial dysfunctions that result in headaches, seizures, and progressive dementia. The authors describe a clinical case study of gastrointestinal manifestations in a pedigree with MELAS, in which all three children, ages 11, 8, and 6, demonstrated acute onset of intestinal obstruction. They unexpectedly showed severe abdominal distension and vomiting. Their parents had no clinical manifestation. The first female sibling underwent an emergent laparotomy because she was diagnosed to have intestinal strangulation. She had postoperative complications caused by progressive lactic acidosis and died the next day. The second and third sisters had similar onsets of the disease and were treated with gastrointestinal decompression and intravenous administration of lactate-free fluid and coenzyme Q10. Genetic testing using blood samples showed an A-to-G point mutation at nucleotide position 3243 in the tRNALeu(UUR) region in the mitochondrial DNA. In MELAS children who demonstrate acute onset of gastrointestinal manifestations, a careful review of family history and an elevation of serum lactate and pyruvate levels may enable a differential diagnosis to be made of acute abdomen to avoid unnecessary surgical intervention.

Pregnancy in the rudimentary horn is rare and represents a form of ectopic gestation. Despite advances in ultrasound, prenatal diagnosis remains elusive, with confirmatory diagnosis being made at laparotomy. Because of variable muscular constitution of the wall of the rudimentary horn, pregnancy can be accommodated until late in pregnancy, when rupture occurs manifesting commonly as acute abdomen with high risk of maternal mortality. The rudimentary horn may or may not communicate with the uterine cavity with majority of cases being non-communicating. We present a case of pregnancy in the communicating horn that was difficult to diagnose which ruptured at 34 weeks and a review of literature.

In the Emergency Department it is mandatory to establish the diagnosis and the prognosis of acute pancreatitis as soon as possible. To evaluate whether the association of serum lipase either with serum beta2-microglobulin or with C-reactive protein allows simultaneously to establish the diagnosis and the prognosis of acute pancreatitis, 96 patients with acute abdomen were studied. Fifty-eight patients had non-pancreatic acute abdomen and the remaining 38 had acute pancreatitis: 23 mild acute pancreatitis, and 15 severe acute pancreatitis. Forty healthy subjects were studied as controls. Lipase, beta2-microglobulin and C-reactive protein were determined in the serum of all subjects, using commercial kits. One patient with acute pancreatitis was not correctly classified when lipase was used to discriminate between patients with non-pancreatic acute abdomen and those with acute pancreatitis. For the discrimination of patients with severe acute pancreatitis from those with the mild form of the disease in the remaining 37 acute pancreatitis patients, beta2-microglobulin had a sensitivity of 53.3 %, specificity of 81.8%, and prognostic accuracy of 70.3 % (27 of the 37 patients correctly classified); 87.5 % of the 96 cases were correctly classified. C-reactive protein showed a lower prognostic accuracy than beta2-microglobulin: sensitivity 86.7%, specificity 45.5%, accuracy 62.2 %; 84.4 % of the cases were correctly classified. Using the polychotomous logistic regression analysis we found the same accuracy in discriminating between patients with acute pancreatitis and those with non-pancreatic acute abdomen (99.0%) but a lower accuracy (54.1%) between patients with severe acute pancreatitis and those with the mild form of the disease. Our study shows that the association of serum lipase with beta2-microglobulin or with C-reactive protein is not useful in simultaneously establishing the diagnosis and prognosis of acute pancreatitis.

The aim of this study was to determine the effectiveness of 'fast-tracking' in an academic emergency department (ED) during a period of limited resources and space constraints. This was a prospective, double-blind, comparative clinical trial. Fast-tracking was applied every other day between 08.00 and 17.30 hours. Patients meeting fast-tracking criteria, which were determined as allergy, dyspepsia, hypertension, urinary tract infection, urolithiasis, gastroenteritis, upper airway infection, minor lacerations, and soft tissue injuries with no sign or symptom of life-threatening illness or acute abdomen, were treated by a designated fast-tracking team. In the alternate days fast-tracking was not done, and the patients having the same criteria were recorded and followed as the control group. ED length of stays were determined for each patient, and at time of discharge a questionnaire was applied to determine patient satisfaction. Follow-up was performed by telephone survey at the 5th day of discharge. The median length of stay was 36 minutes for the fast-tracked group compared with 63 minutes for the control group. The application of fast-tracking decreased ED length of stay and improved patient satisfaction in patients presenting with allergy, dyspepsia, upper airway infection, minor laceration, and soft tissue injury, but not in patients with gastroenteritis, urinary tract infection, hypertension, and urolithiasis. The rate of follow-up was 81% (n = 217), and there were no complications or hospitalizations to another hospital. It is concluded that fast-tracking is an applicable and useful system in an academic ED with limited resources, and decreases ED length of stay and improves patient satisfaction in a selected group of patients. Determination of fast tracking criteria must be individualized for each hospital according to resources. Additionally, fast-tracking seems to be safe when performed under strict criteria for patient selection.

Bowel obstruction is an acute alarming situation with limited diagnostic conditions. Therapeutic decisions must be taken in time. Diagnostic differentiation between incomplete or complete bowel obstruction, intestinal obstruction and paralytic ileus is often uncertain and the underlying cause difficult to detect. Besides plain films in acute abdomen the ultrasound examination presents important additional informations: 1st Dilated intestinal loops and gas caps correlate with the characteristic x-ray finding, i.e. erected dilated intestinal loops with fluid levels. The location of the obstruction is defined in small bowel obstruction by differentiation between jejunum (with Kerckring folds) and ileum (without Kerckring folds). In large bowel obstruction the caecum is dilated and a collapse of the distal colon is detectable. 2nd Additional sonographical findings are: oedema of the intestinal walls, hyperpendulum peristalsis or absence of peristalsis, sedimentation of intestinal contents, pearlstring-like lined up gas bubbles under the ventral intestinal walls, and concomitant ascites. Duplex sonographical studies of the intestinal peristalsis may help to differentiate between mechanical obstruction and paralytic ileus. 3rd In bowel obstruction stenoses can be detected as a result of tumour, Crohn's disease diverticulitis, invagination, strangulated hernias or gall stone ileus. Intestinal adhesions cannot be found by ultrasound. Small and large bowel is dilated in paralytic ileus. Numerous causes like acute pancreatitis, ureteral colic, free gastrointestnal perforation and so on can be diagnosed. 4th In ileus of vascular disorder early diagnosis is high important, but inspite of colour flow imaging diagnostic possibilities are limited. 5th Sonographical diagnosis is of special interest when the x-ray plain films is "empty". The lack of massive fluid collection and meteorism allows an optimal ultrasound examination. In this early phase disorders of peristalsis and intestinal walls are reliably found, and it is easier to find the cause of bowel obstruction. In this way the definitive diagnosis can be arrived at earlier, because it still takes up to 6 hours to obtain the classical x-ray finding. There is a rule that the earlier ultrasound is done, the more findings one will get.

Of the anomalies affecting the urachus, fibrous hamartoma is an extremely rare pathology. In particular, in adults it is very unusual for this pathology to assume clinical relevance, producing symptoms typical of acute abdomen. Diagnosis is only confirmed by histological examination and it is impossible to diagnose prior to surgery; hamartoma of the urachus shows no peculiar characteristics during radiological and ultrasonographic imaging to allow its precise diagnosis and is usually interpreted as ovarian cysts or another mobile abdominal neoformation in the peritoneal cavity. The case reported here, which is documented by photographic images, contributes to the scarce bibliography on this topic.

When colonic carcinomas present with acute abdomen, the operating surgeon and the pathologist face a plethora of diagnostic and therapeutic problems. In this retrospective study of 92 cases of carcinoma colon, 4 presented with acute intestinal obstruction of which three had a turbulent post operative period and died. The resected colonic segment showed on gross examination cobblestone appearance characteristic of Crohn's disease but microscopically was ischemic with the stricture site showing features of an infiltrating poorly differentiated adenocarcinoma. We have made an attempt to study the various pathologic features and analyse their significance with reference to prognosis.

BACKGROUND: Although unusual, but not rare, obstruction in the vicinity of the jejunojejunostomy in Roux-Y gastric bypass (RYGBP) can progress in a very short period of time to a life-threatening situation. METHODS: Over a 10-year period in 1,174 RYGBPs, we have seen seven instances of acute and subacute partial to complete small bowel obstructions in the vicinity of the jejunojejunostomy, which can lead to acute gastric dilatation due to obstruction of the bilio-pancreatic limb. Signs and symptoms of the obstruction may include tachycardia, oliguria, hypotension, severe epigastric pain with or without a palpable mass in the epigastrium, chronic bile regurgitation and bilious vomiting, and a possible increase in serum amylase. Laboratory data otherwise has not been helpful, and although a palpable abdominal mass may be diagnostic, the best tools have been radiologic, i.e. the acute abdomen series, limited upper GI series in the patients that appear to be only partially obstructed, abdominal ultrasound and probably most importantly, CT of the abdomen. RESULTS: In the seven cases presented, diagnoses included internal hernia, adhesions, an idiopathic spontaneous hematoma of the bowel wall and retrograde intussusception at the jejunojejunostomy. CONCLUSIONS: Since many surgeons who perform bariatric surgery are alone in their community, they should train their non-bariatric surgical colleagues and associates to be aware of these potential deadly problems.

After colonoscopy with polypectomy, a patient developed a surgically acute abdomen. Although abdominal radiology did not show free air, a presumptive diagnosis of bowel perforation was made and laparotomy performed. At the time of surgery the colon was normal, and there was no peritoneal contamination. A loop of ileum was discovered incarcerated into an internal paracecal hernia. The bowel was freed, and the operation was completed without need for resection. Several cases of incarcerated inguinal hernia resulting from endoscopy are described in the medical literature; this is the first reported case of an incarcerated internal hernia as a complication of colonoscopy.

Pooling of blood in the spleen is a frequent occurrence in children with sickle cell diseases, particularly in the first few years of life, resulting in what is termed "splenic sequestration crisis." The spectrum of severity in this syndrome is wide, ranging from mild splenomegaly to massive enlargement, circulatory collapse, and even death. The diagnosis is usually clinical, based on the enlargement of the spleen with a drop in hemoglobin level by > 2 g/dl, and it is rare that imaging studies are ordered. However, in the patient who presents to the emergency department with non-specific findings of an acute abdomen, it is important to recognize the appearance of sequestration on imaging studies. We studied seven patients utilizing contrast-enhanced CT scans and found two distinct patterns--multiple, peripheral, non-enhancing low-density areas or large, diffuse areas of low density in the majority of the splenic tissue. Although radiological imaging is not always necessary to diagnose splenic sequestration, in those situations where this diagnosis is not immediately obvious, it makes an important clarifying contribution.
