Introduction: Acute intestinal obstruction (AIO) is a syndrome defined by the cessation of intestinal transit caused by an obstacle or paralysis of intestinal peristalsis. It is a diagnostic and therapeutic emergency. The multi-bar CT scan has revolutionized the management of this pathology, as it allows the surgeon to answer different questions. The aim of our study was to describe the CT aspects of AIO, to determine the etiologies and to show the place of CT in the management of AIO. Material and Method: This was a retrospective descriptive study conducted over 5 years (January 2010 to December 2015) on 81 patient files collected in the imaging departments of the CHU Aristide Le Dantec and the Hôpital Principal. The files retained were those whose diagnosis was established from the clinic, imaging and/or not from surgery. Results: Mechanical occlusions represented 94.4% (76 cases) and functional occlusions 5.6% (05 cases). They were of the small bowel type in 70% of cases and colonic in 30%. The elementary lesions found were: transitional zone (36 patients), feces sign (28 patients), beak sign (06 patients), whirlpool sign (11 patients), signs of severity (36 patients). Seventytwo patients received surgery and 04 patients received medical treatment. The preoperative diagnosis was confirmed by surgery in 68 patients. Surgery corrected the diagnosis in 04 cases. Signs of severity were confirmed at surgery in all our patients. Conclusion: The CT scan has a major role in the therapeutic choice of AIO. It should be requested in first intention before an occlusive syndrome. [ABSTRACT FROM AUTHOR]

The objective of this work was to study the place of ultrasound in the positive diagnosis, etiology and choice of the therapeutic modality of acute intestinal intussusception. Material and methods: This was a retrospective, descriptive, cross-sectional, multicenterstudy, carried out over a period of 18 months (January 1, 2016 to June 30, 2017) on 45 patient files collected in the radiology departments (Aristide Le Dantec and Albert Royer). Were included all patients aged less than 14 years, admitted with acute abdominal pain, whose diagnosis of IIA was retained on ultrasound. Pneumatic disinvagination was performed in patients without signs of severity. We studied the time of management, the ultrasound aspects of the invagination puddles, the therapeutic choice but also the radiosurgical concordance and the factors of failure of the pneumatic enema. Statistical analysis was done by SPSS version 21.0 software. Results: Ultrasound was used to make the diagnosis of IIA in 43 cases (95.5%). The sonographic characteristics were as follows: 27.9% of the IIA were located in the right hypochondrium, 19 cases were ileo-caecal, 10 (22.2%) ileo-caeco-colic, 9 (20%) ileo-colic, 4 (8.9%) colocolic and one (2.2%) gregelic; 44 cases were idiopathic and one case was a Meckel's diverticulum The management time was less than 48 hours in 34% of cases and 66% more than 48 hours. Pneumatic reduction was performed in 18 cases (40%), with success in 14 cases (77.8%) and one case of pneumoperitoneum complication. Surgery was performed in 31 cases (68.8%). The sensitivitý and specificity of ultrasound in the diagnosis of signs of severity were 77.7% and 78.9%. Good agreement was observed between the results of the Doppler ultrasound and the intraoperative findings. Ultrasound parameters associated with failed pneumatic deinvagination were: outer cylinder thickness ≥10 mm, adenopathy at the level of the small-axis bladder ≥10 mm, effusion in the bladder, and hypovascularization of the bladder head. Hypovascularization of the boudin head was the only factor independently associated with failure of pneumatic disinvagination. Conclusion: Ultrasound is a powerful imaging modality in the positive diagnosis, etiology, severity and therapeutic choice of IIA. [ABSTRACT FROM AUTHOR]

The abdominal pseudocyst is a rare complication that can occur in subjects with a ventriculoperitoneal drain (VPD). We report the case of an 11-year-old adolescent with congenital hydrocephalus antecedent, for whom a ventriculoperitoneal shunt was made. He presented a progressive abdominal distension without notion of transit disorders. Abdominal ultrasound and uroscanner revealed an organized peritoneal effusion of great abundance, thin and regular wall, exerting a mass effect on the bladder and the ureters responsible for bilateral uretero-hydronephrosis. Above all, it has made it possible to individualize the distal ventriculo-peritoneal bypass catheter projecting in the effusion., (Le comité de rédaction se réserve le droit de renvoyer aux auteurs avant toute soumission à l'avis des lecteurs les manuscrits qui ne seraient pas conformes à ces modalités de présentation.
