Volvulus de l'intestin grêle comme cause primaire d'abdomen aigu [Volvulus of the small intestine as a cause of primary acute abdomen].

As a cause of small intestine occlusion, volvulus is often a consequence of a band or adhesions. Except in infants, it is rarely the primary cause of symptomatology. Between January 1976 and December 1992, 13 patients (7 women and 6 men, mean age of 56.8 years) were admitted in our department for an acute abdomen due to a spontaneous primary volvulus of the small bowel. Clinical examination and laboratory tests did not help in preoperative diagnosis. All patients underwent an explorative laparotomy. Six patients had had prior abdominal surgery but none of them presented adhesion or band. In 8 patients (62%), detorsion was sufficient. Resection of a segment of small bowel was necessary in 4 patients. Gangrenous of the entire bowel was observed in one patient who rapidly died. Two patients presented minor complications. One patient with Down syndrome died of bronchoaspiration. One patient has been reoperated on one year later for recurrence of the volvulus, and underwent a Noble procedure. We conclude that volvulus of the small bowel is a rare cause of acute abdomen that must be remembered. Early surgery is mandatory to reduce the risk of gangrene, which is known to double the mortality. Laparoscopy will be helpful in early diagnosis and therapy.

Ultraschalldiagnostik des nichttraumatischen akuten Abdomens: die Ursachen ausserhalb des Gastro-Intestinaltraktes [Ultrasound of non traumatic acute abdomen: extra-digestive causes]

In recent years, management of abdominal pain in emergency care units (ECU) has undergone a radical change. Chronic work overload of ECU and increase in severity and complexity of cases required an optimal medical imaging method, such as ultrasound, to establish an accurate diagnosis as quickly as possible. A great variety of causes may cause acute abdominal pain and the role of sonography is to accurately distinguish between these aetiologies. For the application of sonography, perhaps more so than with other imaging methods, a perfect knowledge of sonographical characteristics and technical possibilities is essential to achieve an optimal answer. The purpose of this review is to present and discuss the sonographic characteristics of extra-digestive causes of acute abdominal pain such as splenic infarction, thoracic pathologies, urinary and gynaecologic diseases or retroperitoneal pathologies.

Acute abdomen secondary to complete tubular colonic duplication.

We report the case of a 6-month-old infant who presented with a complete duplication of the large intestine, debuting clinically with acute abdomen and severe metabolic disorders. We discuss the pathogenesis and morphology of the lesions, diagnostic difficulties and peculiarities of surgical treatment.

Acute ulcerative jejunal diverticulitis: case report of an uncommon entity.

Jejunal diverticulosis is a rare entity with variable clinical and anatomical presentations. Its reported incidence varies from 0.05% to 6%. Although there is no consensus on the management of asymptomatic jejunal diverticular disease, some complications are potentially life threatening and require early surgical treatment. We report a case of an 88-year-old man investigated for acute abdominal pain with a high biological inflammatory syndrome. Inflammation of multiple giant jejunal diverticulum was discovered at abdominal computed tomography (CT). As a result of the clinical and biological signs of early peritonitis, an emergency surgical exploration was performed. The first jejunal loop showed clear signs of jejunal diverticulitis. Primary segmental jejunum resection with end-to-end anastomosis was performed. Histopathology report confirmed an ulcerative jejunal diverticulitis with imminent perforation and acute local peritonitis. The patient made an excellent rapid postoperative recovery. Jejunal diverticulum is rare but may cause serious complications. It should be considered a possible etiology of acute abdomen, especially in elderly patients with unusual symptomatology. Abdominal CT is the diagnostic tool of choice. The best treatment is emergency surgical management.

L'orientation du patient souffrant d'un syndrome douloureux abdominal aigu a domicile [Hospitalisation criteria for the acute abdominal pain patient seen at home or in an ambulatory setting].

Dealing at patient's home with an acute abdominal pain may be particularly challenging for the primary care physician. In such a clinical situation, the part of laboratory and radiological investigations is increasing in the diagnostic process. The decision to keep the patient at home based on a clinical evaluation alone may represent a great medical responsibility for the physician. Emergency departments (ED) are of course in charge of investigating such patients with a wide panel of investigation techniques. But these structures are chronically overcrowded resulting frequently in long and difficult periods of waiting. Based on a literature review, a description of useful clinical symptoms and signs is summarized and should help the decision process for the orientation of the patient.

Le syndrome douloureux abdominal (SDA) aux urgences: quelle analgésie [Acute abdominal pain: what about analgesia]

Acute abdominal pain tends not to be treated by surgeons and emergency physicians. However, literature has become clear that analgesics are effective and do not disturb clinical examination, diagnostic process and do not delay surgery. Thus, early treatment of acute abdominal pain is recommended. In the absence of scientific evidence, protocols must be established by each institution and validated by quality process.

Invasive enteritis by Strongyloides stercoralis presenting as acute abdominal distress under corticosteroid therapy.

Overwhelming helminthiasis is still a problem in endemic areas, especially in immunocompromised patients. We report a case of invasive intestinal strongyloidiasis that was clinically expressed as acute abdominal distress in a 73-year-old man from São Paulo who had been receiving methylprednisone, 20 mg/day, for one year for osteoarthritis. A surgical specimen from the ileum revealed invasive enteritis with severe infestation by Strongyloides stercoralis. The patient died of sepsis 6 days after surgery. The possibility of invasive strongyloidiasis should be considered in the differential diagnosis of acute abdominal distress in patients undergoing immunosuppressive therapy.

Acidosis D-Láctica secundaria a síndrome de intestino corto.

The short bowel syndrome appears for the reduction of intestinal absorptive surface due to functional or anatomical loss of part of the small bowel. We present the case of a 35-year-old woman with severe short bowel syndrome secondary to acute intestinal ischemia in adults, who presented at 5 years of evolution episodes of dizziness with gait instability and loss of strength in hands. The diagnosis was D-lactic acidosis. D-lactic acidosis is a rare complication, but important for their symptoms, of this syndrome. It is due to a change in intestinal flora secondary to an overgrowth of lactic acid bacteria that produce D-lactate. D-lactic acidosis should be looked for in cases of metabolic acidosis in which the identity of acidosis is not apparent, neurological manifestations without focality and the patient has short bowel syndrome or patients who have had jejunoileal bypass surgery. Appropriate treatment usually results in resolution of neurologic symptoms and prevents or reduces further recurrences.

Cisto de úraco em adultos simulando abdômen agudo

Urachus anomalies are generally asymptomatic, but when infected can simulate acute abdomen. This anomaly has to be deemed when abdominal tenderness is associated with inflammation signs in parumbilical or hypogastric regions. Ultrasonography has great sensibility to settle down the diagnosis as observed from our three cases. Ultrasonography images with air suggest intestinal fistula in most cases with sigmoid or ileum as shown here.

Abdome agudo: ruptura espontânea de bexiga como um importante diagnóstico diferencial

A case of spontaneous perforation of the bladder in a diabetic female patient is reported. It is a rare clinical condition, that should be suspected in patients with a past history of radiotherapy to the pelvis, enterocystoplasty and those suspected of having a tumor in the bladder. A general surgeon should be aware of this possibility in the differential diagnosis of an acute abdomen.

Abdome agudo como manifestação inicial de melanoma metastático: relato de caso

The malignant melanoma is a relatively common neoplasia, with origin generally in the melanocytics cells in the skin, but with presentation of other possible primary lesions, being presented in this, a case witnessed of liver and mesentery metastases with unknown primary sites.

Outcome of the acute abdomen in patients with previous spinal cord injury

Background: Patients with spinal cord injury (SCI) have always posed difficulties for the diagnosis of an acute abdomen. The aim of the present study was to define this problem retrospectively at Princess Alexandra Hospital and to assess the results of treatment for these patients. Methods: A retrospective review was conducted of 133 SCI patients admitted with an acute abdomen in the 16 years prior to this analysis at the Spinal Injuries Unit (SIU) of Princess Alexandra Hospital. There were 21 patients who conformed to the study criteria. All the patients had sustained traumatic SCI at or above the level of T11, more than 1 month prior to admission. Results: There were 13 male and eight female patients. The time lapse between SCI and the onset of an acute abdomen ranged from 1.5 months to 27 years. The age range was 26-79 years. The majority of patients had C6 injuries (six patients). There were 18 patients with injury levels above T6 and three patients with injuries below this level. The time taken to diagnose the cause of the acute abdomen ranged between 1 day and 3 months. Investigations were found to be useful in making the diagnoses in 61.9% of cases. There were 14 patients who had surgical interventions. Five patients had surgical complications and there were two deaths in the study. The length of follow up was 1-132 months. The mortality in the study was 9.5%. Conclusion: An aggressive approach to the diagnosis and treatment of the acute abdomen in SCI patients with suspicious symptoms is recommended. A high index of suspicion should be maintained in those patients with pre-existing SCI who present with abdominal trauma.

Radiologists' vs. surgeons' reading performance in non traumatic acute abdomen CTs : P32

Purpose: Emergency room reading performances have been a point of interest in recent studies comparing radiologists to other physician groups. Our objective was to evaluate and compare the reading performances of radiologists and surgeons in an emergency room setting of non-traumatic abdominal CTs. Methods and materials: A total of ten readers representing four groups participated in this study: three senior radiologists and visceral surgeons, respectively, and two junior radiologists and surgeons, respectively. Each observer blindedly evaluated a total of 150 multi-slice acute abdominal CTs. CTs were chosen representing established proportions of acute abdomen pathologies in a Level I trauma centre from 2003 to 2005. Each answer was interpretated as right or wrong regarding pathology location, diagnosis and need for operation. Gold standard was the intraoperative result, and the clinical patient follow-up for non-operated patients. Significance was assumed at a p <.05 level. Results: Senior radiologists had a mean score of 2.38 ± 1.14, junior radiologists a score of 2.34 ± 1.14, whereas senior surgeons scored 2.07 ± 1.30 and junior surgeons 1.62 ± 1.42. No significant difference was found between the two radiologist groups, but results were significantly better for senior surgeons as compared to junior surgeons and better for the two radiologist groups as compared to each of the surgeon groups (all p <.05). Conclusion: Abdominal CT reading in an acute abdomen setting should continue to rely on an evaluation by a radiologist, whether senior or junior. Satisfying reading results can be achieved by senior visceral surgeons, but junior surgeons need more experience for a good reading performance.

Obstructive acute abdomen due to intestinal intussusception in adolescent

Introduction: Intestinal intussusception is a rare disease out of childhood. It is represented by an invagination of a bowel into the lumen of the adjacent segment. Case Report: This article reports a case of 14 year-old patient presenting intestinal obstruction caused by an intussusception at the level of the terminal ileum. A surgical resection of the invaginated segment was done and the histopathological study disclosed no evidence of malignancy. Discussion: In children, it is usually idiopathic, but among adolescents and adults it is often related to anatomic lesions, some of them neoplastic with high risk of malignancy. Preoperative diagnosis of intestinal intussusception is difficult due to its nonspecific and subacute symptoms. Computed tomography and ultrassonography can confirm the intussusception through characteristic images. Conclusion: Intestinal intussusception in adolescents is a rare and often misdiagnosed disease, deserving special attention from surgeons and general doctors.
