Hepato-pancreato-biliary surgery in West Africa: a timely capacity assessment.

BACKGROUND: West Africa has among the highest rates of hepato-pancreato-biliary (HPB) malignancies in the world. Although surgery is critical for treatment, the availability of HPB surgery in Africa is unknown. This cross-sectional study investigated the current HPB surgical capacity of West African hospitals. METHOD: The Surgeons OverSeas Personnel, Infrastructure, Procedure, Equipment, and Supplies (PIPES) survey was modified to include HPB-specific parameters and quantify capacity. The survey was completed by consultant surgeons from West Africa. A PIPES index was calculated, and a higher score corresponded to greater HPB surgical capacity. RESULTS: The HPB PIPES survey was completed by 35 institutions from The Gambia, Ghana, Ivory Coast, and Nigeria. Most institutions (94.2%) were tertiary referral centres; five had an HPB-trained surgeon. The most commonly available procedure was an open cholecystectomy (91.4%), followed by gastric bypass (88.6%). Major hepatic resections (14.3%) and the Whipple procedure (17.1%) were rare. ICU capabilities were present at 88.6% of facilities while interventional radiology was present in 25.7%. CONCLUSIONS: This is the first HPB capacity assessment in Africa. This study showed the limited availability of HPB surgery in West Africa. These results can be used for regional quality improvement initiatives and as a baseline for future capacity assessments.

Challenges of practicing neuro-endovascular interventions in a resource-limited country; Ghana in focus.

OBJECTIVE: Now is the time to reflect on the situation of neuro-endovascular interventions (NEVT) in Africa, particularly Ghana, and to renew our commitment to provide high-quality health care to our people. This evaluation is significant because it seeks to assess progress toward our goals and identify potential obstacles for remedial action and to highlight the challenges of NEVT in Ghana. METHODS: Retrospective review of all endovascular treatments performed between January 1, 2019, and December 31, 2021, at two Ghanaian hospitals. A descriptive analysis was done having entered data in Microsoft Excel utilizing frequencies and percentages. Four experienced specialist radiologists discussed NEVT issues in Ghana. The fishbone diagram was used to depict the challenges and problems of NEVT practices in Ghana. RESULTS: From January 2019 to December 2021, 278 patients' records were analyzed at two Ghanaian hospitals. The majority of patients (71.9%) had digital subtraction angiography of the head and neck. The high cost of medical supplies, lack of vendor interest, and limited awareness of symptoms by general practitioners were noted as obstacles associated with neuro-endovascular treatment in Ghana. CONCLUSION: Although the future of NEVT is bright, Interventional Neuroradiologists and other stakeholder need to make conscious effort to improve quality, accessibility, and cost of NEVT in Ghana.

Radiologic patterns of distant organ metastasis in advanced breast cancer patients: Prospective review of computed tomography images.

BACKGROUND: Breast cancer (BC) metastases to the abdomen and pelvis affect the liver, mesentery, retroperitoneum, peritoneum, bladder, kidney, ovary, and uterus. The study documented the radiological pattern and features of the chest, bone, abdominal and pelvic (AP) metastases among advanced BC patients. AIM: The aim is to document the radiological pattern and features of breast cancer metastasis in the chest, abdomen, pelvis and bones. MATERIALS AND RESULTS: Chest, abdominal, and pelvic computed tomography scan images of 36 patients with advanced BC were collated from Cape Coast Teaching Hospital and RAAJ Diagnostics. The images were prospectively assessed for metastasis to the organs of the chest, AP soft tissues, and bones. Radiologic features of metastasis of the lungs, liver, lymph nodes (LNs), and bones were documented. Patients' demographics, clinical data, and histopathology reports were also collected. The data were captured using UVOSYO and exported to Microsoft Excel templates. The data obtained were descriptively analyzed. Only 2.8% of BCs exhibited metaplastic BC, whereas 97.2% had invasive ductal BC. Triple-negative cases were 55.6%. Of 36 patients, 31 (86.1%), 21 (58.3%), and 14(38.8%) were diagnosed of chest, AP, and bone tissues metastasis, respectively. LN involvement was reported in 26 (72.2%) patients. Majority, 21 (58.3%) were diagnosed of multiple sites metastasis with 15 (41.7%) showing single site. Lungs (77.4%, 24/31) and liver (47.6%, 10/21) were the most affected distant organs. Most bone metastases were lytic lesions (92.9%, 13/14) with the vertebrae (85.7%, 12/14) been the most affected. CONCLUSION: According to the study, advanced BC patients have a higher-than-average radiologic incidence of lung, liver, bone, and LN metastases.

Imaging patterns of the arterial supply of the prostate gland in adult Ghanaian men.

Background: Prostatic arterial embolization (PAE) is a novel procedure in West Africa and Ghana. A thorough understanding of the prostate artery's (PA) anatomy and pattern is required for successful prostatic arterial embolization and to guarantee targeted intervention. This study focuses on prostate arterial supply in adult males, including prevalence, variability, and imaging pattern. Methodology: A prospective cross-sectional study was conducted, at Euracare Advanced Diagnostics and Heart Centre. Patients who presented for Computed Tomography Angiography of the pelvis were included in the study. A total of 52 males were included and 104 pelvic CT angiography (one for each side) were analyzed, including: prostatic artery diameter, prostatic gland volume and prostate artery branching pattern. The PA branching pattern was classified using de Assis et al. classification. Result: Thirty-seven (71.15%) men had enlarged prostate volume (>30ml). On each side there was only one prostatic artery and no accessory one was found. Only three types of arterial branching were identified: type I, II,III. The type I artery was the most common origin 58.7% (61/104). PA originating from the anterior division of the internal iliac artery (type II) and the type III is from the internal pudendal artery, accounted for 16.3% (17/104) and 25% (26/104) respectively. Conclusion: The most frequent type of PA origin was type I followed by type III then II. Knowing the different and most frequent types of anatomy of PA may help standardization and effectiveness of the PAE in developing countries.

Contrast Medium Use in Computed Tomography for Patients Presenting with Headache: 4-year Retrospective Two-Center Study in Central and Western Regions of Ghana.

Background: Contrast medium (CM) administration during computed tomography (CT) enhances the accuracy in the detection and interpretation of abnormalities. Evidence from literature also validate the essence of CM in imaging studies. CT, by virtue of its ubiquity, ease of use, speed, and lower financial footprint, is usually the first investigation in cases of headache. Through a multicenter retrospective analysis, we compared findings of contrast-enhanced CT (CECT) to noncontrast-enhanced CT (NCECT) head examinations among patients presenting with headache. Methods: A multicenter retrospective analysis of four years' CT head examination data at two radiology centers located in Central and Western Regions of Ghana were reviewed. Records of patients who presented with headache as principal complaint between January 2017 and December 2020 were reviewed. A total of 477 records of patients with headache were identified, retrieved and evaluated. A Chi-square test and Fisher exact test were used to compare the CECT and NCECT groups. Binary logistic regression analysis was computed to assess association between CECT and each CT findings. Statistical significance was considered at p < 0.05 with a 95% confidence interval. Results: A significant proportion of the patients was females (51.8% in CECT and 60% in NCECT). The NCECT group (40.06 ± 14.76 years) was relatively older than the CECT group (38.43 ± 17.64 years). There was a significant difference between the CECT and NCECT in terms of age (p=0.002) and facility CT was performed (p < 0.0001). The rate of abnormalities was higher in CECT (43.5%, 166/382) compared NCECT (37.9%, 36/95). There was no significant association between CT head findings and contrast enhancement. Conclusion: CECT examination accounted for 5.6% increase in the detection of head abnormalities. Efforts required to establish local standard operation procedures (SOPs) for contrast medium use especially in CT head examinations. Further studies to improve the knowledge of agents, mechanism of action, and safety of contrast media used among practitioners in Ghana is recommended.
