Adult ileocecal intussusception induced by adenomatous ileal polyp: case report and literature review.

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.

[Stomach cancer: a descriptive study of 101 cases at the gastrointestinal endoscopy center at Aristide Le Dantec University Hospital]. / Le cancer gastrique : étude descriptive de 101 cas dans le centre d'endoscopie digestive du CHU Aristide Le Dantec.

INTRODUCTION: Stomach cancer is a real public health problem in Black Africa. We report its epidemiological, endoscopic, and histological aspects, as observed in our gastrointestinal endoscopy center at Aristide Le Dantec University Hospital in Dakar (Senegal). PATIENTS AND METHODS: This retrospective study covered the 5-year period from January 1, 2006, to December 31, 2010 and included all patients with stomach cancer confirmed by anatomo-pathological examination. We collected data about age, sex, indications for the examination, and description of the gastric lesions and any other associated lesions from the upper GI endoscopy reports. We also recorded information from the histological reports of all lesions. RESULTS: The study included 101 patients. The incidence of gastric cancer was 20 cases/year. Patients' mean age was 58 years [range: 24-83]. The sex ratio was 2.48. The main indications for the upper GI endoscopy were epigastralgia (33.3%), vomiting (26.1%), and tumoral hepatomegalia (10.81%). The examination found mainly ulcerative and protruded lesions (59.40%). Other types of lesions associated with the tumor were esophageal candidiasis (34.6%), peptic esophagitis (25%), and gastroesophageal junction incompetence (25%). The tumor was located in the antrum in 68% of the cases and was an adenocarcinoma in 83.2%. CONCLUSION: A cancer register to determine the characteristics and prevalence of stomach cancer in Senegal would be useful. The link with Helicobacter pylori requires further study.

Perforated mesenteric Meckel's diverticulum in an adult: a real variant?

A Meckel's diverticulum is the most common congenital anomaly of the gastrointestinal tract. It is a real diverticulum that is usually located on the anti-mesenteric edge in the last meter of the ileum. Its location on the mesenteric edge has been rarely reported. It may lead to several complications including perforation that may be life-threatening for the patient. We report herein a case of perforated mesenteric Meckel's diverticulum in an adult patient. Upon surgical exploration by laparotomy, we found a perforated Meckel's diverticulum located on the mesenteric edge of the ileum 60 cm from the ileocoecal junction and 400 ml of seropurulent peritoneal fluid. The patient underwent a segmental ileal resection and an end-to-end anastomosis. The postoperative outcomes were marked by a persistent peritonitis that required successful revision surgery.

[Severe acute colitis: two fatal cases in Dakar]. / La colite aiguë grave : deux observations mortelles à Dakar.

OBJECTIVE: Severe acute colitis (SAC) is one of the major complications of inflammatory bowel disease (IBD), especially ulcerative colitis, and it is life-threatening. Although IBD is considered rare in sub-Saharan Africa, we report 2 fatal cases of SAC in Senegalese patients with ulcerative colitis in Dakar. CASES: One patient was a 73-year-old man and the other a 35-year-old woman. In both cases, the diagnosis was preceded by a chronic dysenteric syndrome (febrile in the woman). Despite antibiotic treatment for potential infectious colitis, both patients' condition worsened. Second-line treatment of parenteral corticosteroids did not prevent the occurrence of intestinal perforation for the man, who developed multiorgan failure. The woman developed toxic megacolon during antibiotic treatment, and it was fatal despite bolus corticosteroids: cardiovascular collapse with shock (case 2) occurred before emergency surgery could begin. Conclusion: in subtropical zones where infectious colitis predominates, it is important to consider the diagnosis of SAC in patients with ulcerative colitis and to begin appropriate treatment despite the fear of infection and the difficulty of accessibility to endoscopic exploration.

[Oro-dental treatments in the child under general anesthesia (apropos of an initial case)]. / Les traitements bucco-dentaires chez l'enfant sous anesthésie générale (a propos d'un premier cas).

Oro-dental treatments under General Anesthesia (G.A.) depend on precise indications and the expected results in some cases in Pediatric Dentistry. In this report we have an indication case of oro-dental treatment under G.A. That clinical case has allowed us to record the difficulties that we face in Dakar in order to realize effectively that technics. That case has also allowed us to ascertain the necessity to integrate that practice in the training board in Pediatric Dentistry. Actually, the clinical indications of oro-dental treatments under G.A. are more and more numerous, and in some cases, the dentist intervention becomes a necessity. Moreover, the technics of intervention under G.A. for some patients is the more indicated technics to reach the expected objectives.
