IntroductionDiaphragmatic injuries include wounds and diaphragm ruptures, due to a thoracoabdominal blunt or penetrating traumas. Their incidence ranges between 0.8 and 15 %. The diagnosis is often delayed, despite several medical imaging techniques. The surgical management remains controversal, particularly for the choice of the surgical approach and technique. The mortality is mainly related to associated injuries. The aim of our study was to evaluate the incidence of diaphragmatic injuries occuring in thoraco-abdominal traumas, and to discuss their epidemiology, diagnosis and treatment.Patients and methodsWe performed a retrospective study over a period of 21 years, between January 1994 and June 2015 at the Department of General Surgery of the Aristide Le Dantec hospital in Dakar, Senegal. All patients diagnosed with diaphragmatic injuries were included in the study.ResultsOver the study period, 1535 patients had a thoraco-abdominal trauma. There were 859 cases of blunt trauma, and 676 penetrating chest or abdominal trauma. Our study involved 20 cases of diaphragmatic injuries (1.3 %). The sex-ratio was 4. The mean age was 33 years. Brawls represented 83.3 % (17 cases). Stab attacks represented 60 % (12 cases). The incidence of diaphragmatic injury was 2.6 %. The wound was in the thorax in 60 % (seven cases). Chest radiography was contributory in 45 % (nine cases). The diagnosis of wounds or ruptures of the diaphragm was done preoperatively in 45 % (nine cases). The diaphragmatic wound was on the left side in 90 % (18 cases) and its mean size was 4.3 cm. The surgical procedure involved a reduction of herniated viscera and a suture of the diaphragm by “X” non absorbable points in 85 % (17 cases). A thoracic aspiration was performed in all patients. Morbidity rate was 10 % and mortality rate 5 %.ConclusionThe diagnosis of diaphragmatic rupture and wounds remains difficult and often delayed. They should be kept in mind in any blunt or penetrating thoraco-abdominal trauma. Diaphragmatic lesions are usually located on the left side. Surgery is an efficient treatment.

IntroductionSupravesical hernias develop at the supravesical fossa between the remnants of the urachus and the left or right umbilical artery. They are often the cause of intestinal obstruction. We describe the anatomical variant of the supravesical hernia in this case and discuss the pre-operative findings revealed by computed tomography. We discuss diagnostic and therapeutic procedures, and review other anatomical variants.Case presentationA 60-year-old Senegalese man was admitted with a two-day history of small bowel obstruction. A physical examination showed abdominal distension. An abdominal X-ray revealed dilated small bowel loops. A computed tomography scan showed an image at the left iliac fossa that suggested an intussusception. A median laparotomy showed a left lateral internal supravesical hernia. The hernia was reduced and the defect was closed. The patient recovered uneventfully.ConclusionsSupravesical hernia is a possible cause of intestinal obstruction and diagnosis is very often made intraoperatively. Morphological examinations, such as computed tomography scanning, can lead to a preoperative diagnosis. Laparoscopy may be useful for diagnosis and therapy.

IntroductionSplenic pseudocysts are nonparasitic cyst without epithelial lining. We report this case especially by its way of revelation, its large size and its per operative presentation which needed total splenectomy. To this opportunity, we discuss the diagnostic procedure and therapeutic indications.Case presentationA twenty-year old Senegalese woman, was admitted with a three-month history of spontaneous abdominal mass associated with a pain. Ultrasonography and CT scan found the giant splenic pseudocyst with a diameter of 20 cm which needed a total splenectomy by median laparotomy.ConclusionUsually, symptomless splenic cysts are untreated. When surgical treatment is indicated, recommendations are to preserve splenic parenchyma by partial splenectomy or fenestration especially by laparoscopy. Total splenectomy retains some guidance.

Intussusception is a rare cause of bowel obstruction in adults, and has generally an organic etiology. However, adenomatous polyp of the small bowel is an uncommon etiology. Moreover, there’s a great difference with childhood intussusception in its presentation, etiology and management. We describe herein a case of adult ileocecal intussusception due to an adenomatous ileal polyp with a preoperative diagnosis made on computed tomography. We performed a right hemicolectomy, without attempting to reduce the intussusception, and an end-to-end ileotransverse anastomosis. The pathological examination of the surgical specimen revealed an adenomatous polyp with a high grade dysplasia on the terminal ileum, being the cause of the ileocecal intussusception.

Malaria remains a major problem in African countries despite substantial decreases in morbidity and mortality due to sustained control programs. Studies for the evaluation of qualitative or quantitative Ab responses to key targets of anti-plasmodium immunity were mostly done in rural endemic setting compared to urban area. In a cohort of 200 patients with mild malaria and living in Dakar, we analyze total and subclasses IgG responses to a panel of P. falciparum blood stage antigens: MSP1p19, MSP3, EB200, GST-5 and R23. A mean age of 15 yrs (4 to 56 yrs) and parasitemia between 0.1 to 17% were found. Levels of IgG anti-MSP3 were higher in patients with low parasitemia (≤1%) and appear negatively correlated to parasite densities (Rho =. 0.54; p= 0.021). This correlation is more significant in children (≤ 15 yrs). In addition, an increase of IgG responses against MSP1p19 is highly observed in adults having a parasitemia less than 1%. In those patients, we find that IgG1 subclasses were predominant (p <0.01). Our study shows an association between Ab responses and parasitemia. This association is dependant to IgG anti-MSP3 in children and IgG anti-MSP1p19 in adults living in urban area.

La dilatation aiguë de l'estomac est une pathologie rare. Elle est classiquement observée en psychiatrie dans les troubles du comportement alimentaire. Le diagnostic préopératoire est difficile et fait appel à la radiologie. La mortalité liée aux complications varie entre 80% et 100%. Nous rapportons 2cas de dilatation aiguë de l'estomac prises en charge au service de Chirurgie Générale de l'Hôpital Aristide Le Dantec de Dakar dont l'une était compliquée de nécrose et l'autre d'une rupture gastrique. Il s'agissait de 2 patients dont l'un était de sexe masculin âgé de 32 ans et l'autre de sexe féminin âgée de 36 ans. Ils étaient reçus dans un tableau de douleurs abdominales aiguës et un état de collapsus cardiovasculaire. L'examen avait retrouvé un syndrome d'irritation péritonéale chez les 2 patients. A la biologie, on notait une anémie chez tous les patients. A la radiographie de l'abdomen sans préparation, on notait un pneumopéritoine massif chez le patient et un gros niveau hydro-aérique chez la patiente. Le diagnostic préopératoire était une péritonite par perforation d'organe creux chez le patient et une occlusion intestinale aiguë chez la patiente. Après une réanimation, la laparotomie avait permis de retrouver une dilatation énorme de l'estomac avec une large rupture au niveau de la petite courbure chez le patient et une dilatation importante de l'estomac avec une nécrose du fundus chez la patiente. Une suture de la petite courbure était réalisée chez le patient et une gastrectomie atypique fundique chez la patiente. Les suites opératoires étaient marquées par un décès chez le patient au deuxième jour post-opératoire et une sténose gastrique chez la patiente nécessitant une gastrectomie totale.La dilatation aiguë de l'estomac est une pathologie rare. Son diagnostic aux urgences est difficile car les signes ne sont pas spécifiques. Les formes compliquées donnent un tableau d'abdomen chirurgical aigu. L'exploration chirurgicale pose le diagnostic. Le traitement des complications va de la suture à la gastrectomie. La mortalité dans les formes compliquées est élevée.

IntroductionSitus inversus is a congenital anomaly characterized by the transposition of the abdominal viscera. When associated with dextrocardia, it is known as situs inversus totalis. This condition is rare and can be a diagnostic problem when associated with appendicular peritonitis.Case presentationWe report the case of a 20-year-old African man who presented to the emergency department with a 4-day history of diffuse abdominal pain, which began in his left iliac region and hypogastrium. After examination, we initiated a surgical exploration for peritonitis. We discovered a situs inversus at the left side of his liver, and his appendix was perforated in its middle third. A complementary post-operative thoracic and abdominal tomodensitometry revealed a situs inversus totalis.ConclusionAppendicular peritonitis in situs inversus is a rare association that can present a diagnostic problem. Morphologic exploration methods such as ultrasonography, tomodensitometry, magnetic resonance imaging, and laparoscopy may contribute to the early management of the disease and give guidance in choosing the most appropriate treatment for patients.
