Pull-Through for Hirschsprung's Disease: Insights for Limited-Resource Settings From Mbarara.

INTRODUCTION: In many resource-limited settings, patients with Hirschsprung's Disease (HD) undergo initial diverting colostomy, followed by pull-through, and finally, colostomy closure. This approach allows for decompression of dilated and thickened bowel and improved patient nutritional status. However, this three-stage approach prolongs treatment duration, with significant stoma morbidity, costs, and impact on quality of life. Our aim was to determine whether pull-through for HD can safely be performed with simultaneous stoma closure, reducing treatment approach from three to two stages. METHODS: Children with HD and diverting colostomy were prospectively followed as they underwent pull-through with simultaneous stoma closure. Their in-hospital course and 3-mo outpatient course were assessed for postoperative complications. Patients with total colonic HD, redo pull-through, and residual dilated colon were excluded from the study. RESULTS: Of the 20 children, 17 were male (n = 17, 85%). All patients had rectosigmoid HD. The median weight, age at colostomy formation, and age at pull-through were 11.05 kg (interquartile range [IQR] 10-12.75), 0.9 y (IQR 0.25-2.8), and 2.08 y (IQR 1.28-2.75), respectively. Mean duration with colostomy before pull-through was 1.1 y (standard deviation 1.51). Median hospital length of stay was 6 d (IQR 5-7). Early complications included anastomotic leak (n = 1), perianal skin excoriation (n = 2), surgical site skin infection (n = 3), and fascial dehiscence (n = 1). Longer-term complications included stricture (n = 1, 5%) and enterocolitis (n = 2, 10%). CONCLUSIONS: In this small case series, we have demonstrated that pull-through with simultaneous stoma closure can be safely performed in resource-constrained settings. Further studies are needed to understand the quality of life and economic impact of this change in management for HD patients.

Pediatric Emergency Surgery Course in Uganda: Long-Term Follow-Up and Insights From Further Dissemination.

INTRODUCTION: Approximately 170 pediatric surgeons are needed for the 24 million children in Uganda. There are only seven. Consequently, general surgeons manage many pediatric surgical conditions. In response, stakeholders created the Pediatric Emergency Surgery Course (PESC) for rural providers, given three times in 2018-2019. We sought to understand the course's long-term impact, current pediatric surgery needs, and determine measures for improvement. METHODS: In October 2021, we distributed the same test given in 2018-2019. Student's t-test was used to compare former participants' scores to previous scores. The course was delivered again in May 2022 to new participants. We performed a quantitative needs assessment and also conducted a focus group with these participants. Finally, we interviewed Surgeon in Chiefs at previous sites. RESULTS: Twenty three of the prior 45 course participants re-took the PESC course assessment. Alumni scored on average 71.9% ± 18% correct. This was higher from prior precourse test scores of 55.4% ± 22.4%, and almost identical to the 2018-2019 postcourse scores 71.9% ± 14%. Fifteen course participants completed the needs assessment. Participants had low confidence managing pediatric surgical disease (median Likert scale ≤ 3.0), 12 of 15 participants endorsed lack of equipment, and eight of 15 desired more educational resources. Qualitative feedback was positive: participants valued the pragmatic lessons and networking with in-country specialists. Further training was suggested, and Chiefs noted the need for more trained staff like anesthesiologists. CONCLUSIONS: Participants favorably reviewed PESC and retained knowledge over three years later. Given participants' interest in more training, further investment in locally derived educational efforts must be prioritized.

Efforts to improve outcomes among neonates with complex intestinal atresia: a single-center low-income country experience.

PURPOSE: Intestinal obstruction caused by intestinal atresia is a surgical emergency in newborns. Outcomes for the jejunal ileal atresia (JIA), the most common subtype of atresia in low-income countries (LIC), are poor. We sought to assess the impact of utilizing the Bishop-Koop (BK) approach to JIA in improving outcomes. METHODS: A retrospective cohort study was performed on children with complex JIA (Type 2-4) treated at our national referral hospital from 1/2018 to 12/2022. BK was regularly used starting 1/1/2021, and outcomes between 1/2021 and 12/2022 were compared to those between 1/2018 and 12/2020. Statistical significance was set at p < 0.05. RESULTS: A total of 122 neonates presented with JIA in 1/2018-12/2022, 83 of whom were treated for complex JIA. A significant decrease (p = 0.03) was noted in patient mortality in 2021 and 2022 (n = 33, 45.5% mortality) compared to 2018-2020 (n = 35, 71.4% mortality). This translated to a risk reduction of 0.64 (95% CI 0.41-0.98) with the increased use of BK. CONCLUSION: Increased use of BK anastomoses with early enteral nutrition and decreased use of primary anastomosis improves outcomes for neonates with severe JIA in LIC settings. Implementing this surgical approach in LICs may help address the disparities in outcomes for children with JIA.

Treatment abandonment in children with Wilms tumor at a national referral hospital in Uganda.

INTRODUCTION: The incidence of pediatric Wilms' tumor (WT) is high in Africa, though patients abandon treatment after initial diagnosis. We sought to identify factors associated with WT treatment abandonment in Uganda. METHODS: A cohort study of patients < 18 years with WT in a Ugandan national referral hospital examined clinical and treatment outcomes data, comparing children whose families adhered to and abandoned treatment. Abandonment was defined as the inability to complete neoadjuvant chemotherapy and surgery for patients with unilateral WT and definitive chemotherapy for patients with bilateral WT. Patient factors were assessed via bivariate logistic regression. RESULTS: 137 WT patients were included from 2012 to 2017. The mean age was 3.9 years, 71% (n = 98) were stage III or higher. After diagnosis, 86% (n = 118) started neoadjuvant chemotherapy, 59% (n = 82) completed neoadjuvant therapy, and 55% (n = 75) adhered to treatment through surgery. Treatment abandonment was associated with poor chemotherapy response (odds ratio [OR] 4.70, 95% confidence interval [CI] 1.30-17.0) and tumor size > 25 cm (OR 2.67, 95% CI 1.05-6.81). CONCLUSIONS: Children with WT in Uganda frequently abandon care during neoadjuvant therapy, particularly those with large tumors with poor response. Further investigation into the factors that influence treatment abandonment and a deeper understanding of tumor biology are needed to improve treatment adherence of children with WT in Uganda.

Pediatric surgery backlog at a Ugandan tertiary care facility: COVID-19 makes a chronic problem acutely worse.

BACKGROUND: 1.7 billion of the world's 2.2 billion children do not have access to surgical care. COVID-19 acutely exacerbated this problem; delaying or preventing presentation and access to surgical care globally. We sought to quantify the effect of COVID-19 on children requiring surgery in Uganda. METHODS: Average monthly incident, elective pediatric surgical patient volume was calculated by sampling clinic logs before and during the pandemic, and case volume was quantified by reviewing operative logbooks for all surgeries in 2020 at Mulago Hospital, Kampala. Disability-Adjusted Life Years (DALYs) resulting from untreated disease were calculated and used to estimate economic impact using three different models. RESULTS: Expected elective pediatric surgery cases were 956. In 2020, pediatric surgery at Mulago was limited to 46 elective cases, approximately 5% of the expected incident cases, leading to a backlog of 910 patients and a loss of 10,620.12 DALYs. The economic impact of more than 10,000 disability years in Uganda is conservatively estimated at $23 million USD with other measures estimating ~ $120 million USD. CONCLUSION: The COVID-19 pandemic limited access to pediatric surgery in Uganda, making a chronic problem acutely worse, with costly consequences for the children and health system.

Impact of Bowel Coverage and Resuscitation Protocol on Gastroschisis Mortality in Low-Income Countries: Experience and Lessons From Uganda.

BACKGROUND: Gastroschisis causes near complete mortality in low-income countries (LICs). This study seeks to understand the impact of bedside bowel reduction and silo placement, and protocolized resuscitation on gastroschisis outcomes in LICs. METHODS: We conducted a retrospective cohort study of gastroschisis patients at a tertiary referral center in Kampala, Uganda. Multiple approaches for bedside application of bowel coverage devices and delayed closure were used: sutured urine bags (2017-2018), improvised silos using wound protectors (2020-2021), and spring-loaded silos (2022). Total parental nutrition (TPN) was not available; however, with the use of improvised silos, a protocol was implemented to include protocolized resuscitation and early enteral feeding. Risk ratios (RR) for mortality were calculated in comparison to historic controls from 2014. RESULTS: 368 patients were included: 42 historic controls, 7 primary closures, 81 sutured urine bags, 133 improvised silos and 105 spring-loaded silos. No differences were found in sex (p = 0.31), days to presentation (p = 0.84), and distance traveled to the tertiary hospital (p = 0.16). Following the introduction of bowel coverage methods, the proportion of infants that survived to discharge increased from 2% to 16-29%. In comparison to historic controls, the risk of mortality significantly decreased: sutured urine bags 0.65 (95%CI: 0.52-0.80), improvised silo 0.76 (0.66-0.87), and spring-loaded silo 0.65 (0.56-0.76). CONCLUSION: Bedside application of bowel coverage and protocolization decreases the risk of death for infants with gastroschisis, even in the absence of TPN. Further efforts to expand supply of low-cost silos in LICs would significantly decrease the mortality associated with gastroschisis in this setting. TYPE OF STUDY: Treatment Study. LEVEL OF EVIDENCE: III (Retrospective Comparative Study).

Anatomy and lessons of partnerships in global pediatric surgery.

Partnerships in Global Surgery have evolved over several decades and continue to do so based on reports from different experiences and collaborations. These should be characterised by their objectives, leadership and "championship," communication, ethics and equity. Partnerships take the form of academic collaborations or clinical support whose details vary with the different stakeholders involved. Over time, these have evolved based on challenges, successes, and failures. Recently, quality improvement activities have been increasingly initiated with locally derived information. This has come from local databases in low and middle income country (LMIC) settings whose maintenance and analysis have been done through academic collaborations. For many sites in LMICs, there would be very little advance in paediatric surgery without collaborations. Despite this, problems still arise from collaborations due to failure to learn from past problems, lack of local championship, poor communication, and externally driven objectives. For success and longevity, the collaboration must pay attention to unique the needs of the site, champions and equity.

Surgical neonates in a low-resource setting: Baseline nutrition and outcome assessment.

INTRODUCTION: Congenital anomalies necessitating prolonged fasting have a high mortality in low-income settings, partially due to malnutrition and electrolyte disturbances in the absence of parenteral nutrition (PN). Interventions to address these problems require an accurate baseline quantification of the morbidity and mortality of this population. This prospective study aimed to determine peri-operative morbidity, fluid and electrolyte disturbance, growth, and mortality in neonates with gastroschisis (GS), intestinal atresia (IA), and esophageal atresia (EA) in Uganda. METHODS: Standardized patient care of 45 neonates treated in Uganda from Oct 2021 to March 2022 with protocolized fluid and nutrition, vital signs, and routine laboratory measurements. Patient demographics, admission and hospital characteristics are described with mean ± SD. Characteristics of survivors and non-survivors were compared with Fischer's exact tests, logrank tests, and CoX Ph model. RESULTS: Twenty-eight (62.2%) patients had GS, 4 (8.9%) EA, and 13 (28.9%) IA. Thirty-six percent (16/44) of patients survived to discharge (26% GS, 50% EA, 54% IA) with an average length of stay of 17.3 days ( ± 2.2) (survivors) and 9 days ( ± 1.7) (non-survivors). Average weight was 2.21 kg ( ± 0.62) at presentation, with no significant weight change during the study. Abnormal serum sodium in 64%, phosphate 36.5%, and magnesium 20.8% of measurements. Mortality did not correlate with diagnosis (p = 0.47), electrolyte derangement, or weight change. CONCLUSION: Mortality of neonates born with GS, EA, and IA is high in Uganda. Malnutrition and fluid/electrolyte derangements are common and may affect mortality. This study provides a comparison group for studying interventions to improve outcomes for these populations. TYPE OF STUDY: Prospective cohort. LEVEL OF EVIDENCE: Level 3.

Pediatric abdominal trauma in a National Referral Hospital.

Background: Trauma is a major contributor to pediatric morbidity and mortality. Injury and violence are a major killer of children throughout the world. Unintentional injuries account for almost 90% of these cases. They are the leading cause of death for children aged 10-19 years. More than 95% of all injury deaths in children occur in low income and middle-income countries. Abdominal trauma is present in approximately 25% of pediatric patients with major trauma and is the most common cause of unrecognized fatal injury in children. Objectives: To describe the patterns, the management and outcomes of pediatric abdominal trauma.This was a descriptive retrospective study. Data was extracted from the Pediatric surgery Unit database from January 2012 to July 2019 on all abdominal trauma admissions to the unit. Results: Falls were the commonest (51.3%) mechanism for trauma on the unit. Most (84%) of the admissions had blunt abdominal trauma, with the majority (77%) managed non operatively. Only 16% had penetrating trauma, with the majority (84%) of these managed operatively. The average length of hospital stay for most (71.9%) of the patients was less than 7 days, with 96.1% of all admitted patients being discharged upon recovery. Conclusion: Blunt abdominal trauma is the most common pattern of pediatric abdominal trauma, with majority of these patients being managed non-operatively with good outcomes. Selective non-operative management for penetrating pediatric abdominal trauma has good patient outcomes as well.

High incidence of acute kidney injury among patients with major trauma at Mulago National Referral Hospital, Uganda: risk factors and overall survival.

Introduction: Acute kidney injury (AKI) is a common and life-threatening complication of major trauma. Recognition is often delayed and management is frequently sub-optimal. We determined the incidence, risk factors and immediate outcomes of AKI in patients with major trauma at Mulago National Referral Hospital. Methods: This was a prospective study. We recruited adult patients with ISS of > 16. The KDIGO criteria was used to stage AKI. Serum creatinine was measured at baseline, 24, 48, 72 hours and on discharge from the study. Participants were followed up for seven days if not yet discharged. Bivariate and multivariate analysis was done using modified Poisson regression with robust standard errors. Results: 224 patients were recruited. The incidence was 67/1000 persons per day. The risk factors were male sex, delayed presentation, hypoglycemia at admission, RR=1.62 (95%CI 1.24-2.12) and non-operative management RR=1.39 (95%CI 1.02-1.89). Out of the 62 patients that died, 34 (54.8%) had AKI. The overall mortality rate was 39.5 patients per thousand per day. Conclusion: There was a high incidence of AKI among patients with major trauma. Efforts to reduce morbidity and mortality should be prioritized.

Prevalence and risk factors of gallstone disease in patients undergoing ultrasonography at Mulago hospital, Uganda.

BACKGROUND: Gallstone disease (GSD) is the most prevalent medical condition in the pancreatobiliary system. The burden of GSD and its complications are major public health issues globally. It is a common cause of surgical intervention, contributing substantially to health care costs. Most patients are asymptomatic, however 20% become symptomatic after 10 years. Its prevalence differs among populations and remains unknown in Uganda. OBJECTIVE: To determine the prevalence and risk factors of GSD in patients undergoing abdominal ultrasonography at Mulago hospital, Uganda. METHODS: This was a cross-sectional study at the Department of Radiology in Mulago hospital. Convenient sampling was used to recruit individuals having an abdominal ultrasound scan. Questionnaires were used to assess risk factors, and an abdominal exam was performed for individuals with gallstones to assess symptomatology. RESULTS: The prevalence of GSD was 22%. Statistically significant factors associated with GSD were a history of hormonal contraceptive use OR 3.2 (1.88-5.41) and a history of previous biliary symptoms OR 2.9 (1.68-4.91). Ninety-four percent of individuals with gallstones had epigastric/right upper quadrant pain. CONCLUSION: The prevalence of GSD is high in Mulago hospital; use of hormonal contraceptives and a previous history of biliary symptoms were significant risk factors for GSD in this study. Majority of patients with GSD were symptomatic with epigastric pain as the cardinal symptom. We recommend a countrywide screening program using abdominal ultrasonography to determine the prevalence of GSD in the general population. There is need to study further the risk of hormonal contraceptive use and GSD. Women on these contraceptives should be informed of the potential risk, and offered alternative options where feasible.

Long term bowel function after repair of anorectal malformations in Uganda.

BACKGROUND: Anorectal malformations (ARMs) are common congenital anomalies cared for at Mulago Pediatric Surgery Unit (PSU), similar to other sites in the region. All patients undergo staged repairs and complete treatment at older ages compared to high-income countries (HICs). This is the first study to examine long-term bowel function in our patients and compare with HICs. METHODS: A retrospective cohort study was conducted of all children 3-12 years old with ARMs who had repair between January 2012 and June 2017 and who completed surgical repair at least 6 months prior to the study. Bowel function was measured using the fecal continence scoring system derived from Rintala and Lindahl (1995). As in prior studies, patients were classified by score into four categories: Poor (6-9); Fair (9-11); Good (12-17); and Normal (18-20). RESULTS: Median follow up was 2 years post stoma closure. Long-term bowel function was Normal/Good in 65% (C.I 27, 45), and Fair/Poor 35% (C.I 55, 73), with soiling in 49% (C.I 40, 59), constipation in 23% (C.I 16, 32); and incontinence in 39% (C.I 30, 39). There was no statistically significant association between bowel function and multiple demographic, social, and clinical factors. Median age at completion of treatment (stoma reversal) was 2.3 years old, and median duration of colostomy (interval between stoma placement and takedown) was 1.8 years. CONCLUSION: Despite definitive repair at older age and almost two years of living with a stoma, our patients achieve fair long-term bowel function. Nonetheless, improved follow up and timely management of complications may improve outcomes soiling, incontinence and constipation. LEVEL OF EVIDENCE: Level II.
