Background: This project analyses all iatrogenic injuries from our department over the last decade and tracks their rate against several interventions.

Methods: All patients who sustained an iatrogenic injury between 2012 and 2022 were reviewed.

Results: A total of 946 iatrogenic injuries occurred in 731 patients. Sixty per cent of these patients were male; the median age was 39 years. Of 946 injuries, 574 (60.7%) occurred during an operation, and 372 (39.3%) were not related to an operation. Of the operative injuries 412 (71.8%) were enteric injuries. Of the 372 non-operative iatrogenic injuries 304 (82%) were due to indwelling devices (ID), and 34 (10%) occurred during flexible endoscopy. Fifty-five per cent of the injuries due to ID were due to central venous catheters (CVC) and urinary catheters (UC). CVC contributed toward 31% of all non-operation related iatrogenic injuries. One in 54 admissions (946/51 178) and one in 47 (574 /27 342) patients undergoing an operation sustained an iatrogenic injury. The annual rate of iatrogenic injuries did not decrease over the decade despite a multifaceted approach to reduce them. Interventions included electronic database development, procedural standardisation, and checklist implementation.

Conclusion: Despite multiple interventions over a decade, our rate of iatrogenic injury remains constant. Ongoing multifaceted efforts to reduce this rate must focus on engendering a culture of safety at all levels of healthcare if we hope to match the enviable safety record of the aeronautics industry.

Background: Documentation on the spectrum, comorbidities, profile, and outcomes of adult surgical admissions in Botswana is limited. This information may guide manpower distribution for proposed rotations in the new general surgery training programmes.

Methods: The medical records of adult surgical admissions for a period of one year (August 2017 - July 2018) were reviewed retrospectively. Demographics, types of admissions, dates of admission and discharge, and known comorbidities were captured and the outcomes were analysed.

Results: Of the 2610 admissions the mean age was 44.4 years and 60.8% were male. Gastrointestinal tract (GIT), neurosurgical, and cardiothoracic admissions constituted 60.7%. Emergency admissions constituted 50.1%. Comorbidities were found in 45.6% of the admissions, and HIV-prevalence was 697/1822 (38.3%) among known HIV-status patients. Elective admissions underwent more surgical procedures, 776/1303 (59.6%), p = 0.001 (COR 1.9, 95% CI:1.7-2.3). A total of 220/2610 complications (8.4%) were documented, including 42/1355 (3.1%) superficial surgical site infections and 159/2610 deaths (6.1%). Hypertension and diabetes mellitus were associated with higher mortality, p = 0.002 (COR 1.8,95% CI:1.2-2.6) and p = 0.031 (COR 1.9, 95% CI:1.1-3.4) respectively. HIV-positive patients had longer hospital stays than HIV-negative patients, p = 0.001 (COR 1.03, 95% CI:1.02-1.04). HIV-positive admissions with CD4 count < 200 had significantly higher composite complication and mortality rate than those with ≥ 200, p = 0.002 (COR 3.03, 95% CI:1.52-6.04) and p = 0.001 (COR 4.34, 95% CI:2.08-9.05) respectively.

Conclusion: Contributions of emergency and elective admissions were even. A higher burden of diseases was found in gastroenterology. The higher mortalities associated with hypertension, diabetes, and CD4 count < 200 warrant further study.

Summary: Gestational gigantomastia is a rare condition typified by disproportionate bilateral breast enlargement in pregnant women, resulting in skin thinning, ulceration, and bleeding. Less than sixty cases have been documented worldwide, and only one other in South Africa. Pseudo-angiomatous stromal hyperplasia (PASH) is a rare benign proliferation of stromal tissue in a tumorous or diffuse pattern. This, to the best of our knowledge, is the first published case, a 27-year-old human immunodeficiency virus (HIV) positive woman, to present with both conditions concurrently. Medical management with cabergoline was initiated and, seven months post-delivery, a novel Goldilocks mastectomy was performed with acceptable outcomes.

Background: Perforation of peptic ulcer (PPU) is the most morbid complication of peptic ulcer disease (PUD) with scant recent reports from sub-Saharan Africa. The aim of this study was to describe a PPU series from a single centre in South Africa and contrast the findings with other recent reports from sub-Saharan Africa.

Methods: A retrospective study of PPU at Kalafong Hospital in Pretoria was performed. The relationship of patient demographics, risk factors, ulcer pathology and severity scores to mortality were analysed. Recent similar reports from sub-Saharan Africa were reviewed and the findings compared to the current study and findings from high income countries (HIC).

Results: The study comprised 121 patients. The majority were black men with an average age of 46.6 years, with few comorbidities. A large proportion of patients admitted to risk factors and most presented to hospital 48 hours after the onset of symptoms. The majority (71%) of the perforations occurred in the stomach. The patient sex, age, risk factors and the mortality at 4% were similar to other African studies, although perforations were mainly duodenal in most of the African studies. The median age of patients in the East African studies was lower by 13 years. Patients in HIC series of PPU were older, more likely to be female, have duodenal perforations and a higher mortality than in the African series.

Conclusion: Patients were mostly smokers, presented late to hospital and had gastric perforations. The findings of low mortality and male predominance concurred with those of other sub-Saharan African reports and were the opposite of trends in HIC.

Background: This study aimed to compare factors contributing to a positive outcome of adult burn injury patients managed at two primary and one tertiary level Western Cape hospitals. These patients from the primary hospitals (PLHs) met the referral criteria for specialised care at the Tygerberg Hospital burns unit (TBU) but were not accepted or were accepted late.

Methods: A total of 1034 adult burn injury patients seen at two primary level ("A" and "B") hospitals and the TBU between 2016 and 2019 were retrospectively analysed. One hundred and eleven (111) primary level patients ("A" 71, "B" 40) met the criteria for referral to the TBU. The outcomes and factors contributing to positive outcome of these patients were compared with the 859 patients treated at the TBU during the same period.

Results: Patients treated at the TBU showed longer theatre waiting times, more operations, and higher complication and death rates than their primary level counterparts. The PLHs showed no factors significantly contributing to hospital discharge. At TBU, pregnancy status, younger age, hot water burns, lower abbreviated burns severity index (ABSI) score, and longer time to theatre were associated with hospital discharge. A shortage of beds was the main reason for denial of admission to the TBU.

Conclusion: The PLHs showed good outcomes in managing severe burn injuries, although no significant contributors to a positive outcome were identified. Patient- and facility-related factors contributed to positive outcomes at the TBU. Upgrading both the Western Cape's primary level capabilities and the TBU's accessibility and efficiency are necessary to improve burns services.

Background: Children are less susceptible to infection with SARS-CoV-2 and subsequent severe disease, yet especially vulnerable to the indirect effects of the pandemic. A constrained healthcare service, combined with the societal and behavioural changes observed during the pandemic, is likely to have altered the presentation of paediatric surgical disease. The objective was to investigate the impact of the COVID-19 pandemic on the volume of paediatric surgical admissions, the severity of disease and the type of surgical pathology treated at our centre.

Methods: A retrospective cohort study compared paediatric surgical admissions in an eleven-month period before COVID-19 to the same period during the pandemic. Comparisons in volume and diagnoses were based on the number of admissions. Predetermined criteria for severity of disease using triage scores, intraoperative findings and intensive care admissions were compared.

Results: A total of 1 810 admissions were recorded, 1061 in the pre-COVID group and 749 during COVID. Emergency admissions reduced by 9.2%, most notably due to a reduction in trauma, caustic ingestions and constipation. There was an increase in incarcerated inguinal hernias and helminth-related pathologies. Significantly more intussusceptions failed pneumatic reduction requiring surgical intervention with bowel resection. There was a two-fold increase in patients requiring emergency intensive care.

Conclusion: Paediatric surgical volumes at our centre decreased during the COVID-19 pandemic. There was evidence of more advanced disease on presentation of inguinal hernias and intussusception and a generalised increased demand for emergency ICU admission.

Background: Perforated peptic ulcer (PPU) is associated with significant morbidity and mortality, particularly in low to middle income countries. This study aimed to scrutinise the clinical course of patients diagnosed with PPU and identify modifiable factors to improve outcomes.

Methods: A retrospective review of the hybrid electronic medical record (HEMR) database at Grey's Hospital was performed. All patients diagnosed with PPU between January 2013 and December 2020 were entered into the study. The variables collected include age, ethnicity, comorbid profile, Boey score, type of surgery performed and complications. These factors were analysed to determine the factors responsible for morbidity and mortality.

Results: One hundred and ninety four patients were diagnosed with PPU during the study period. Six patients were treated non-operatively, all of whom survived. In the surgically treated group, omental patch repair was performed in 159 (84.5%) patients, and primary closure in 26 (13.8%) patients. The leak rate was 32% in the cohort that underwent relaparotomy and the overall mortality was 14%. There was no significant relationship between the type of repair performed and outcome. All patients had a Boey score of 1 or more. The following factors were found to increase the probability of in-hospital mortality: age > 40 years (OR: 8.49, 95% CI 2.46-29.29 p < 0.01), female gender (OR: 2.509, CI 0.98-6.37, p = 0.048), need for relaparotomy (OR: 0.398, CI 0.17-0.91, p = 0.027) and Boey score > 1 (OR: 46.437, CI 6.13-350.28, p < 0.01). A Boey score > 1 was the only variable that increased the likelihood of finding a leaking repair at relaparotomy (p < 0.01).

Conclusion: The Boey score was a significant predictor of mortality and leak rate in our patients with PPU. Adding age as a variable may improve the ability to predict mortality in our setting, while the impact of gender and ethnicity needs further investigation.

Summary: Transverse colon volvulus is a rare diagnosis, with less than 100 cases reported up to 2019. The condition is complicated by the absence of characteristic radiological findings and is typically diagnosed intraoperatively. It is a surgical emergency as the condition can lead to bowel necrosis and is associated with a mortality rate of up to 33%. Bowel resection is the treatment of choice, and if a megacolon is present a subtotal colectomy is recommended. Due to the rarity of transverse colon volvulus, limited data is available on the long-term outcome of patients.
