Total pancreatectomy(TP) is a surgical procedure which includes the complete removal of the pancreatic gland, the spleen, the duodenum, the gallbladder, and the distal part of the stomach. TP represents the curative treatment of pancreatic cancer which simultaneously involves the head and the body/tail of the pancreas. Other possible indications for TP comprise multifocal parenchymal diseases, such as intraductal papillary mucinous neoplasms, pancreatic neuroendocrine tumors, multiple endocrine neoplasms, and chronic pancreatitis. Sometimes, TP is carried out in patients scheduled for pancreaticoduodenectomy(where only the head of the pancreas is removed) when a cancer located in the pancreatic head is intraoperatively found to also extend to the pancreatic body [1].

Introduction: In hyperthyroidism, selective irradiation of the thyroid gland with radioactive iodine is a radical treatment and an alternative to surgery. The aim of this review is to assess the medium-term efficacy of outpatient treatment of hyperthyroidism with iodine-131 in Africa. Methods: We identified the studies carried out in Africa on outpatient radiation therapy between 2016 and 2020. For each article included, we noted the country concerned and the year of publication, the numbers studied, the socio-demographic characteristics of the patients, the indications for radio iodine therapy, the dose administered, the results of the hormonal dosage 6 months after radiation. Results: 13 retrospective studies were included to constitute a total population of 925 patients. The average age was 40.77 years, the sex ratio of 1/5.4 with a clear female predominance. The 3 main etiologies of hyperthyroidism justifying outpatient radio iodine therapy were Graves’ disease (55.89%), toxic multinodular goiter (22.70%) and toxic adenoma (21.40%). The average dose of iodine 131 administered per course is 13.7 mCi. No short-and medium-term complications were reported. The radio iodine therapy was effective in 86.08% (n = 796) of the patients with extremes of 72% and 100%. Conclusion: Radio iodine therapy is effective in Africa. It is simple, inexpensive on an outpatient basis and well tolerated. The introduction of outpatient radio iodine therapy could improve the management of patients with hyperthyroidism in Burkina Faso.
