The aim of this study was to report the indications and results of lower digestive endoscopy in a hospital center in Senegal. Patients and Methods: We conducted a descriptive retrospective study from September 1<sup>st</sup>, 2017, to September 30, 2018 at the gastrointestinal endoscopy unit of the regional hospital center of Thiès. All patients received for lower gastrointestinal endoscopy and whose reports were usable, were included. In the reports, we collected and analyzed sociodemographic data, indication and results of the endoscopic examination. Results: We included 250 patients. There were 140 men (sex ratio 1.27). The average age was 42 years [range 1 - 92 years]. There were 37 colonoscopies (14.8%), 51 rectosigmoidoscopies (20.4%) and 162 anorectoscopies (64.8%). The patients were from the region of Thiès in 82% of cases. In most cases, they were most often referred by general practitioners (22.8%) and surgeons (20.8%). The main indications were rectal bleeding (36.8%), hemorrhoidal disease (23.2%) and proctalgia (11.6%). Hemorrhoidal disease (63.6%), anal fistula (14%) and tumors (8.8%) were the most common pathologies. Conclusion: Admitted patients at the gastrointestinal endoscopy unit of the regional hospital center of Thiès have many indications as well as pathologies. Anal pathology is dominated by hemorrhoidal disease.展开更多

The disease can be asymptomatic and discovered incidentally or symptomatic, which is often manifested by abdominal pain and motility disorders (diarrhea, constipation). The clinical presentation can also be alarming with rectal bleeding and obstructive symptoms that may be misinterpreted as a neoplastic process. In this paper, we report the case of a 58-year-old female patient with a previous history of appendicetomy. She presented with persistent abdominal pain, chronic constipation and black colored stools, following Covid-19 infection. The physical examination was unremarkable. Colonoscopy examination found a bulging, non-ulcerated mass, measuring 3.5 cm in greatest dimension, located at the right colic angle. Thoraco-abdomino-pelvic computed tomography was performed and showed right colonic wall thickening and enhanced nodule formation. Furthermore, metastatic localization was not detected. After a multidisciplinary meeting, a laparotomy with right hemicolectomy was performed. Histopathological examination of the surgical specimen revealed nodular lymphoid hyperplasia with CD20+, CD5−, CD10+ and BCL2−phenotype on immunohistochemistry. Besides, lymphocytes in interfollicular area are CD3+ T cells. Patient outcome was favorable after surgery and no additional treatment was necessary. Nodular lymphoid hyperplasia of the colon is a benign process whose endoscopic appearance can sometimes raise suspicion of malignancy. The diagnosis can only be established by histological evaluation. Immunohistochemistry is also essential to confirm the diagnosis and to rule out low-grade lymphoma. Clinical evolution is often favorable. However, endoscopic follow-up is necessary in all cases.展开更多
