Introduction: The gastric polyp is a tumor protruding into the gastric lumen. It is asymptomatic most often with a risk of malignant degeneration closely related to its histological nature. These data are very rare in Africa. Objectives: Reporting the frequency and endoscopic and histological characteristics of gastric polyps in the digestive endoscopy center of Aristide Le Dantec hospital in Dakar. Patients and methods: This was a retrospective study carried out in the digestive endoscopy center of Aristide Le Dantec Hospital in Dakar from January 2012 to December 2016. We have included all patients with one or more gastric polyps coupled with histological findings available. Results: There were 60 patients with gastric polyps, hence a prevalence of 0.8%. We included 37 patients. Their mean age was 46 years [21 years - 75 years]. The sex-ratio was 0.48. Epigastralgia was the most frequent endoscopic indication (51.3%). The polyp was unique in 26 patients (70.3%) with an average size of 6.87 mm [2 - 15 mm]. Polyps were sessile in 31 cases (83.8%) and pediculate in 6 cases (16.2%). They were most often in the antrum (51.4%). Antral erosions (13.5%) and fundic atrophy (13.5%) were the main associated endoscopic lesions. These were hyperplastic polyps in 27% of cases and adenoma in 16.2% of cases. Chronic atrophic gastritis (10.8%) and intestinal metaplasia (10.8%) were the main histological lesions associated with polyps. Helicobacter pylori (Hp) were present in 17 patients (45.9%). Conclusion: The prevalence of gastric polyps is 0.8% in the endoscopy center of Aristide Le Dantec hospital. They are usually hyperplastic or adenomatous.

Introduction: The treatment of Helicobacter pylori (H. pylori) requires the combination of antibiotic therapy with an antisecretory agent. Due to increasing antibiotic resistance, which varies from one geographical region to another, several eradication protocols exist. Objective: The objective is evaluate and compare the efficacy of three treatment regimens for H. pylori infection: 1) Arm A: Omeprazole + Amoxicillin + Clarithromycin for 10 days;2) Arm B: Omeprazole + Amoxicillin + Metronidazole for 10 days;3) Arm C: Sequential treatment = Omeprazole + Amoxicillin for 5 days then Omeprazole + Clarithromycin + Metronidazole for 5 days. Patients and Method: This was a prospective randomised study conducted from February 2016 to July 2016 and from April 2017 to September 2017 in the digestive endoscopy center of the gastroenterology and hepatology department of the University Hospital Center Aristide Le Dantec. Our study population consisted of all patients aged 18 years or older referred for upper GI endoscopy. We included all patients whose indication for the examination was epigastralgia and/or dyspepsia and whose rapid urease test was positive. Patients were randomized to the different treatment arms. A 13C-urea breath test was performed at least 4 weeks after stopping antibiotics and 2 weeks after stopping proton pump inhibitor (PPI). Results: We included 120 patients. There were 95 women and 25 men. The mean age was 40 years. Epigastralgia and dyspepsia were present in 90% and 59% of cases, respectively. Upper G

引用

Open Journal of Gastroenterology 2023年第1期13卷 61-65页

作者： Alioune Badara Fall Marieme Polele Fall salamata diallo Marie Louise Bassene Alsine Yauck Coumba Cisse Tene Sidibe Cheikh Anta Diop University of Dakar Hospital Aristide Le Dantec Dakar Senegal

Biliary cystadenoma is a multilocular cystic benign tumor which arises in the intrahepatic biliary system. Diagnosis is often difficult and based on imaging, however histology remains the only argument for diagnosis certainty. We report a case of biliary cystadenoma in a 69-year-old female. Observation: it was a 69-year-old female with history of RHUPUS syndrome (Lupus + Rheumatoid arthritis) under low-dose corticosteroid therapy. She presented with pain in the right hypochondrium with permanent moderate intensity for 3 months associated to altered performance status. Physical examination showed a hepatomegaly, cervical subluxation, and pulmonary condensation syndrome. Hepatobiliary ultrasound showed presence of multiple septate cystic formations occupying segments 1, 7, 8, 5 of the left liver. Abdominal CT scan and hepatic MRI were in favor of biliary cystadenoma but could not rule out biliary cystadenocarcinoma with certainty. Conclusion: biliary cystadenoma is a benign cystic tumor of the liver. The differential diagnosis with cystadenocarcinoma is most often difficult and usually requires histological analysis for diagnostic certainty.

Introduction: Liver cirrhosis is a global public health issue. Our aim was to determine the epidemiological, clinical, paraclinical and therapeutic aspects of liver cirrhosis in the hepato-gastroenterology department of the hospital Aristide Le Dantec in Dakar. Patients and Methods: We conducted a retrospective study with a descriptive focus covering the period from January 1st, 2010 to December 31, 2020. We included the medical records of patients which presented body of clinical and paraclinical arguments which supported the diagnosis of cirrhosis. The data collected were related to age, gender, clinical, paraclinical, therapeutic and prognosis aspects of cirrhosis and were analyzed with the software Sphinx Plus. Results: Prevalence of cirrhosis was 6.2%. Sex ratio was 2.1%. The average age was 38 years. Asthenia (60.9%), altered performance status (60.1%), abdominal pain (37.2%), gastrointestinal bleeding (29.6%) and abdominal swelling (27.8%) were the most common motives of consultation. Physical examination revealed primarily portal hypertension (74.9%), liver failure (2.4%), hepatomegaly (28.2%) and anemia (13.7%). Viral hepatitis B was the most common etiology (81.9%). Abdominal screening (ultrasound/CT scan) showed hepatomegaly (80.6%), liver dysmorphia (87.7%), portal hypertension signs (85.3%) and portal vein thrombosis (18.2%). 55.1% Patients were classified as Child Pugh A, 33.8% were Child Pugh B and 11.1% were Child Pugh C. Tenofovir Disoproxil Fumarate (TDF) was prescribed to all patients affected by hepatitis B virus only. Evolution was characterized by clinical improvement and prognosis reclassification. Conclusion: Liver cirrhosis is a frequent pathology in the hepato-gastroenterology department of the hospital Aristide Le Dantec in Dakar. It affects young male adult.

作者： salamata diallo Alioune Badara Fall Mamadou Lamine Gueye Marie Louise Bassene Mamadou Ngoné Gueye Marieme Polele Fall Mame Aissé Thioubou Alsine Yauck Department of Gastroenterology and Hepatology Hospital Aristide Le Dantec Dakar Senegal Department of General Surgery Hospital Aristide Le Dantec Dakar Senegal Department of Gastroenterology and Hepatology Hospital Idrissa Pouye Dakar Senegal Department of Gastroenterology and Hepatology Peace Hospital Ziguinchor Senegal

Hepatic artery aneurysm (HAA) is a rare disease. HAA is generally asymptomatic disease when symptomatic, they usually present with abdominal pain, upper gastrointestinal (GI) bleeding and/or jaundice, hypovolaemia secondary to rupture or GI bleeding with normal GI endoscopy. Surgical repair and endovascular treatment are the two therapeutic options available at present. Case report: A 49-year-old male presented at the emergency department with high gastrointestinal bleeding, abdominal pain and jaundice. Gastroscopy showed an ulcer with flat pigmented haematin on ulcer base (Forrest IIc) that was controlled by medical treatment. CT angiography was done and showed aneurysm of the proper hepatic artery almost totally thrombosed measuring 100 × 59 mm associated with signs of contained rupture. Emergency surgery was indicated. The laparotomy objectified a rupture of the aneurysm in the biliary tree in per operative excision of aneurysm and ligation of the hepatic pedicle was carried out. After surgery, the evolution was favorable with a follow-up of 8 months. Conclusion: HAA rupture is a rare cause of upper GI bleeding. The mortality rate after rupture is relatively high. CT angiography or MRI can diagnose a ruptured of HAA. Urgent surgery should be the first choice in patients with a ruptured HAA with active hemorrhage causing hemorrhagic shock.

Introduction: Plummer Vinson Syndrome (PVS) is a rare pathology combining dysphagia, an iron deficiency anemia and a cervical esophageal web. It is one of the risk factors of the esophageal cancer. Objectives: To report the epidemiological, clinical, paraclinical and histological characteristics of patients with Plummer-Vinson syndrome associated with esophageal cancer. Patients and Methods: This was a retrospective study carried out at the digestive endoscopy center of Aristide le Dantec hospital in Dakar from January 2008 to December 2015. We included all patients with Plummer-Vinson syndrome associated with esophageal cancer. Results: We included 7 patients. The mean age was 36 years (24 - 65 years). There were 5 women and 2 men. The mean diagnostic period was 9 months (6 months - 15 years). The main clinical manifestations were dysphagia (100%), weight loss (100%) and clinical anemia (71.4%). The biology showed a mean hemoglobin level of 8.8 g/dl (6 - 11 g/dl), serum iron at 30.8 μg/dl (11 - 52 μg/dl) and ferritinemia at 6.2 ng/dl (1.5 - 25 ng/dl). The upper digestive endoscopy revealed a stenosis web of the cervical esophagus in all patients. An endoscopic dilatation was performed in all cases. After dilation, the endoscopy showed a tumor of the middle third of the esophagus in 4 cases and of the lower third in 3 cases. It was about of a squamous cell carcinoma in the tumors of middle third and of an adenocarcinoma in those of the lower third. Conclusion: At Aristide le Dantec hospital of Dakar, PVS is sometimes associated with an epidermoid carcinoma or an adenocarcinoma of the esophagus. The improvement of the prognosis depends on the early realization of an upper gastrointestinal endoscopy (UGI) in case of any dysphagia and the monitoring of the patients.

Background: Portal thrombosis (PT) is a rare pathology. Its prevalence is estimated at 1%. Its consequences depend on the acute or chronic nature, the extent of the clot and the etiology. In Sub-Saharan Africa, very few studies have been devoted to it. Patients and Method: The objective of our work was to determine the prevalence of PT and to describe its clinical and etiological presentation as well as its therapeutic management in the Hepato-gastroenterology department of the Aristide Le Dantec hospital in Dakar. This was a retrospective, longitudinal and descriptive study during the period from January 1, 2012, to December 31, 2018. It included all patients followed in ambulatory or inpatient, who presented a PT objectively determined by a medical imaging examination (ultrasound and/or CT scan). Age, gender, clinical and radiological aspects, proposed treatments and etiology of PT were collected. Results: We collected 71 observations. The prevalence of PT was 1.9%. The mean age of the patients was 41 years 15 and 75 years. A predominance of men was found with a sex ratio of 2.73. The clinical manifestations were dominated by abdominal pain (74.6%), ascites (35.7%) and gastrointestinal bleeding (25.4%). Imaging allowed the diagnosis to be made in 50 patients on ultrasound and 21 patients on abdominal CT scan. PT was acute in 5 patients and chronic in 66 patients. Thrombosis was complete in 71.4% of cases and extended to the spleno-mesaraic venous trunk and the superior mesenteric vein in 2.8% and 8.4% respectively. Etiological research found cirrhosis complicated by hepatocellular carcinoma in 67.6% of cases, cirrhosis with cruoric thrombosis in 21.1% of cases, a combined protein C and S deficiency in 1.4% of cases. No aetiology was objectified in 9.9% of cases. Treatment with beta-blockers was initiated in 32 patients. Anticoagulant treatment was performed in one patient. Evo

Introduction: As of February 2022, coronavirus disease 2019 (COVID-19) has caused a pandemic affecting all countries, with a total of 399 million patients and 5 million deaths. The lungs are the major organs involved in COVID-19. COVID-19 infection is not limited to the respiratory system but can affect multiple organs including the gastrointestinal tract. The aim of our study was to assess the prevalence of gastrointestinal (GI) symptoms on admission in patients with COVID-19 and their association with adverse outcomes, including mortality. Methods: In a retrospective study, we examined medical record data from patients with SARS-CoV-2 infection admitted to epidemic treatment center of hospital Aristide Le Dantec, Dakar (Senegal) between May 1, 2020, and June 31, 2021. SARS-CoV-2 infection was diagnosed by real-time polymerase chain reaction on nasopharyngeal and throat swabs. We included all patients with SARS-CoV-2 infection and GI symptoms. Result: The study identified 472 hospitalized patients with confirmed SARS-CoV-2 infection during the study period. We recruited 222 patients with gastrointestinal symptoms. The mean age of patients with GI symptoms was 56 years [17 - 90 years], and 54.9% were male. Patients with GI symptoms had comorbidities in 66.2% of cases. Hypertension, diabetes mellitus and chronic kidney disease were the most common comorbidities at 29.3%, 23.9%, and 6.7%, respectively. Patients with GI had cough in 69.4%, shortness of breath in 61.7%, ageusia in 57.6%, and fever in 53.1%. At presentation among patients with GI symptoms, 32.4% had mild disease, 27.5% had moderate disease, and 40.1% had severe disease. The prevalence of digestive manifestations was 47%, and the main digestive manifestations were nausea (27%), diarrhea (17.1%), abdominal pain (17.1%) and vomiting (14.4%). GI symptoms such as abdominal pain, diarrhea, and vomiting were more common in those with hypertension (45%) and those with diabetes (43%). Conclusion: Gastrointestinal

Introduction: Covid-19 is a systemic disease that can spread to all systems. Among the gastrointestinal manifestations, pancreatic involvement can have a major prognostic impact. We report 3 acute pancreatitis cases occurring during Covid-19, in Dakar. Case 1: 65-year-old woman who presented with intense atypical epigastric pain. Physical examination revealed obesity, high blood pressure and abdominal tenderness. Biological tests found increase CRP (134 mg/l) and lipasemia (312 UI/l). Abdominal CT scan showed findings of Balthazar grade C acute pancreatitis. RT-PCR for SARS CoV 2 RT-PCR was positive. The outcome was favorable. Case 2: 56-year-old woman patient with history of nephroangiosclerosis who presented with dyspnea, cough, fever and moderate epigastric pain. Physical examination revealed epigastric tenderness, high blood pressure, anuria. Biological testing, noted increase CRP (96 mg/l), lipasemia (793 UI/l), creatinine (227 mg/l) and urea (3.84 g/l). Abdominal CT scan showed acute edematous pancreatitis findings. SARS CoV 2 RT PCR was positive. The outcome was favorable. Case 3: 27-year-old man who presented with physical asthenia, headache, and epigastric pain. Physical examination found epigastric tenderness. Elevated CRP level was of 102 mg/l and lipasemia level was of 427 UI/l (7N). Abdominal CT scan showed acute edematous pancreatitis findings. SARS CoV 2 RT PCR was positive. The outcome was favorable. Conclusion: Acute pancreatitis can occur during Covid-19 infection. However, the imputability to the Covid-19 disease necessitates to rule out the most common causes.
