Anterior Abdominal Wall Desmoids Tumor in a Five Year Old Girl – A Pre Operative Diagnostic Challenge in Resource-Poor Setting

Desmoid tumors are rare, slow – growing, mesenchymal monoclinic proliferation. It may occur as intra-abdominal tumor usually affecting the mesentery of the intestine or it could be extra-abdominal in which they may affect the popliteal region, the chest wall or the anterior abdominal wall. Reports in children less than 10 years is rare. Here, we report a 5 year old girl with anterior abdominal wall desmoid that was managed in our unit and challenges at reaching a diagnosis are highlighted.

Medical Education Impact Assessment: Knowledge of Final Year Medical Students of Obafemi Awolowo University about Male Urethral Catheterization

Urethral catheterization is one of the commonest procedures performed by doctors either for prophylactic, diagnostic or therapeutic purposes. Themedical education impact of this procedure on graduating medical students was assessed using a structured questionnaire.This is a questionnaire - based study and the respondents were final year medical students who have completed their final examinations.There were 86 respondents with M:F ratio of 1. About a third of the respondents have not done urethral catheterization during their training while only 7% have done the procedure more than 5 times. All the students know that urethral catheterization is a sterile procedure and 96% knew that sterile gloves should be donned during the procedure. 92.4% of the respondents knew that skin preparation was necessary during the procedure with 75% of them responding that cetriomide andchlorhexidine solution was appropriate. 54% of the students used xylocaine as lubricant while 46% used KY Jelly. On the quantity of the lubricant for catheterization, only 2.7% of the respondents felt that 11-15mls should be injected into the urethra. On the maximum amount of fluid to retain the balloon, only 36% of the students respondedthat it should be according to the specified capacity of the balloon. Majority of the students (88%) know that the catheter should get to theY-junction before it is inflated. Most of the students in this study were taught appropriately the procedure of urethral catheterization; however, about a third had not performed the procedure as a medical student.Keywords: Medical education, knowledge, male catheterizatio

Spontaneous retraction of the ligated hernial sac during herniotomy: an accurate guide to successful herniotomy for young surgeons

Inguinal herniotomy is one of the most common surgical procedures in paediatric surgery practice. To most experienced surgeons, herniotomy is supposed to be one of the easiest surgical procedures and one of the many procedures a trainee should be able to perform proficiently. However, this is not usually the experience of young trainees. This communication aims to highlight an intraoperative observation to reassure the ‘uninitiated’ trainee surgeon on the accuracy of the hernial sac ligation

The Undescended Testes in Children: a Prospective Epidemiological Study

Background: The management of undescended testes remains a topical issue. This study was aimed at determinining the presentation and outcome of children presenting with undescended testes at the Lagos University Teaching Hospital (LUTH).Methods: This was a prospective cross-sectional study that included all male children aged 1-15 years with undescended testes who were treated by the paediatric surgery unit in LUTH from January 2010 to December 2011Results: A total of 56 boys with 73 undesecended testes were surgically treated during the study period. The median age at operation was 3.0 years (range: 1 to 11years). Seventeen (30.4%) boys had bilateral undescended testes while 39 (69.6%) boys had unilateral undescended testes . Associated anomalies were present in 6 (10.7%) boys- hypospadias in 5 (8.9%) boys and vertebral anomaly in 1 (1.8%) boy.. Open orchidopexy was performed in 59 (80.8%) cases while stagedorchidopexy was done in 11 (15.1%) cases. There were 4 (5.4%) post operative complications -3 cases of postoperative hematoma and 1 case of wound dehiscence.Conclusion: Children with undescended testes present late in Lagos. About a third of patients with undesended testes in our centre have bilateral undescended testes while about 10% have associated congenital anomalies.Key words: Undescended, Testis, Children, Epideniolog

Preliminary model assessing the cost-effectiveness of preoperative chlorhexidine mouthwash at reducing postoperative pneumonia among abdominal surgery patients in South Africa

Background Pneumonia is a common and severe complication of abdominal surgery, it is associated with increased length of hospital stay, healthcare costs, and mortality. Further, pulmonary complication rates have risen during the SARS-CoV-2 pandemic. This study explored the potential cost-effectiveness of administering preoperative chlorhexidine mouthwash versus no-mouthwash at reducing postoperative pneumonia among abdominal surgery patients. Methods A decision analytic model taking the South African healthcare provider perspective was constructed to compare costs and benefits of mouthwash versus no-mouthwash-surgery at 30 days after abdominal surgery. We assumed two scenarios: (i) the absence of COVID-19; (ii) the presence of COVID-19. Input parameters were collected from published literature including prospective cohort studies and expert opinion. Effectiveness was measured as proportion of pneumonia patients. Deterministic and probabilistic sensitivity analyses were performed to assess the impact of parameter uncertainties. The results of the probabilistic sensitivity analysis were presented using cost-effectiveness planes and cost-effectiveness acceptability curves. Results In the absence of COVID-19, mouthwash had lower average costs compared to no-mouthwash-surgery, $3,675 (R 63,770) versus$3,958 (R 68,683), and lower proportion of pneumonia patients, 0.029 versus 0.042 (dominance of mouthwash intervention). In the presence of COVID-19, the increase in pneumonia rate due to COVID-19, made mouthwash more dominant as it was more beneficial to reduce pneumonia patients through administering mouthwash. The cost-effectiveness acceptability curves shown that mouthwash surgery is likely to be cost-effective between $0 (R0) and$15,000 (R 260,220) willingness to pay thresholds. Conclusions Both the absence and presence of SARS-CoV-2, mouthwash is likely to be cost saving intervention for reducing pneumonia after abdominal surgery. However, the available evidence for the effectiveness of mouthwash was extrapolated from cardiac surgery; there is now an urgent need for a robust clinical trial on the intervention on non-cardiac surgery

COVID-19-related absence among surgeons: development of an international surgical workforce prediction model

Background: During the initial COVID-19 outbreak up to 28.4 million elective operations were cancelled worldwide, in part owing to concerns that it would be unsustainable to maintain elective surgery capacity because of COVID-19-related surgeon absence. Although many hospitals are now recovering, surgical teams need strategies to prepare for future outbreaks. This study aimed to develop a framework to predict elective surgery capacity during future COVID-19 outbreaks. Methods: An international cross-sectional study determined real-world COVID-19-related absence rates among surgeons. COVID-19-related absences included sickness, self-isolation, shielding, and caring for family. To estimate elective surgical capacity during future outbreaks, an expert elicitation study was undertaken with senior surgeons to determine the minimum surgical staff required to provide surgical services while maintaining a range of elective surgery volumes (0, 25, 50 or 75 per cent). Results Based on data from 364 hospitals across 65 countries, the COVID-19-related absence rate during the initial 6 weeks of the outbreak ranged from 20.5 to 24.7 per cent (mean average fortnightly). In weeks 7–12, this decreased to 9.2–13.8 per cent. At all times during the COVID-19 outbreak there was predicted to be sufficient surgical staff available to maintain at least 75 per cent of regular elective surgical volume. Overall, there was predicted capacity for surgeon redeployment to support the wider hospital response to COVID-19. Conclusion: This framework will inform elective surgical service planning during future COVID-19 outbreaks. In most settings, surgeon absence is unlikely to be the factor limiting elective surgery capacity

Laparoscopy in management of appendicitis in high-, middle-, and low-income countries: a multicenter, prospective, cohort study.

BACKGROUND: Appendicitis is the most common abdominal surgical emergency worldwide. Differences between high- and low-income settings in the availability of laparoscopic appendectomy, alternative management choices, and outcomes are poorly described. The aim was to identify variation in surgical management and outcomes of appendicitis within low-, middle-, and high-Human Development Index (HDI) countries worldwide. METHODS: This is a multicenter, international prospective cohort study. Consecutive sampling of patients undergoing emergency appendectomy over 6 months was conducted. Follow-up lasted 30 days. RESULTS: 4546 patients from 52 countries underwent appendectomy (2499 high-, 1540 middle-, and 507 low-HDI groups). Surgical site infection (SSI) rates were higher in low-HDI (OR 2.57, 95% CI 1.33-4.99, p = 0.005) but not middle-HDI countries (OR 1.38, 95% CI 0.76-2.52, p = 0.291), compared with high-HDI countries after adjustment. A laparoscopic approach was common in high-HDI countries (1693/2499, 67.7%), but infrequent in low-HDI (41/507, 8.1%) and middle-HDI (132/1540, 8.6%) groups. After accounting for case-mix, laparoscopy was still associated with fewer overall complications (OR 0.55, 95% CI 0.42-0.71, p < 0.001) and SSIs (OR 0.22, 95% CI 0.14-0.33, p < 0.001). In propensity-score matched groups within low-/middle-HDI countries, laparoscopy was still associated with fewer overall complications (OR 0.23 95% CI 0.11-0.44) and SSI (OR 0.21 95% CI 0.09-0.45). CONCLUSION: A laparoscopic approach is associated with better outcomes and availability appears to differ by country HDI. Despite the profound clinical, operational, and financial barriers to its widespread introduction, laparoscopy could significantly improve outcomes for patients in low-resource environments.

Twelve-month observational study of children with cancer in 41 countries during the COVID-19 pandemic

Introduction Childhood cancer is a leading cause of death. It is unclear whether the COVID-19 pandemic has impacted childhood cancer mortality. In this study, we aimed to establish all-cause mortality rates for childhood cancers during the COVID-19 pandemic and determine the factors associated with mortality. Methods Prospective cohort study in 109 institutions in 41 countries. Inclusion criteria: children &lt;18 years who were newly diagnosed with or undergoing active treatment for acute lymphoblastic leukaemia, non-Hodgkin's lymphoma, Hodgkin lymphoma, retinoblastoma, Wilms tumour, glioma, osteosarcoma, Ewing sarcoma, rhabdomyosarcoma, medulloblastoma and neuroblastoma. Of 2327 cases, 2118 patients were included in the study. The primary outcome measure was all-cause mortality at 30 days, 90 days and 12 months. Results All-cause mortality was 3.4% (n=71/2084) at 30-day follow-up, 5.7% (n=113/1969) at 90-day follow-up and 13.0% (n=206/1581) at 12-month follow-up. The median time from diagnosis to multidisciplinary team (MDT) plan was longest in low-income countries (7 days, IQR 3-11). Multivariable analysis revealed several factors associated with 12-month mortality, including low-income (OR 6.99 (95% CI 2.49 to 19.68); p&lt;0.001), lower middle income (OR 3.32 (95% CI 1.96 to 5.61); p&lt;0.001) and upper middle income (OR 3.49 (95% CI 2.02 to 6.03); p&lt;0.001) country status and chemotherapy (OR 0.55 (95% CI 0.36 to 0.86); p=0.008) and immunotherapy (OR 0.27 (95% CI 0.08 to 0.91); p=0.035) within 30 days from MDT plan. Multivariable analysis revealed laboratory-confirmed SARS-CoV-2 infection (OR 5.33 (95% CI 1.19 to 23.84); p=0.029) was associated with 30-day mortality. Conclusions Children with cancer are more likely to die within 30 days if infected with SARS-CoV-2. However, timely treatment reduced odds of death. This report provides crucial information to balance the benefits of providing anticancer therapy against the risks of SARS-CoV-2 infection in children with cancer
