Management of ambiguous genitalia in ile ife, Nigeria: Challenges and outcome

BACKGROUND Ambiguous genitalia are a major cause of parental anxiety and can create social problems if not properly managed. Diagnosis and management can however be challenging. The aim of this study is to highlight some of the challenges in management of ambiguous genitalia in our environment. PATIENTS AND METHODS All cases of ambiguous genitalia managed at the Paediatric surgical unit of the Obafemi Awolowo University Teaching hospital, Ile Ife, Nigeria, between January 1993 and October 2007 were analysed for age, sex at presentation, investigation modality, and final sex of rearing and outcome of surgery. RESULT Nine patients had surgical reconstruction for ambiguous genitalia during the study period. Their age ranges from 5 weeks to 19 years at presentation. The causes of genital ambiguity in the patients was congenital adrenal hyperplasia (CAH) in 6, true hermaphroditism in 2 and male pseudo-hermaphroditism in 1. Seven patients were reconstructed as females while 2 were raised as males. Change of sex of raring was necessary in 2 patients. CONCLUSION The diagnosis and management of ambiguous genitalia is a challenging problem in our environment. Early presentation and treatment is necessary to avoid psychological and social embarrassment.

Macrostomia: a report of three cases.

Transverse facial clefts (macrostomia) are rare disorders that result when the embryonic mandibular and maxillary processes of the first branchial arch fail to fuse properly to form the corners of the mouth. Macrostomia may be seen alone or in association with other anomalies. It may be unilateral, extending along a line from the commissure to the tragus. It is usually partial, but rarely complete. Transverse facial clefts are more common in males, and commoner on the left when unilateral. We report on 3 patients with macrostomia managed in our unit. There were 2 girls with a bilateral transverse facial cleft and a boy with a left unilateral transverse facial cleft. All had a 3 layered repair of their clefts with Z-plasty repair of the skin. The longest duration of follow-up was 2 weeks. Strict adherence to the principles of surgical reconstruction is advised in the repair of macrostomia to prevent a poor treatment outcome.

Paediatric endoscopy by adult gastroenterologists in Ile-Ife, Nigeria: A viable option to increase the access to paediatric endoscopy in low resource countries

Background: Paediatric endoscopy performed by adult gastroenterologists is a service delivery model that increases the access of children to endoscopy in countries where paediatric gastroenterologists with endoscopy skills are scarce. However, studies on the usefulness of this model in Nigeria and Sub-Saharan Africa are scarce. We aimed to evaluate the indications, procedures, diagnostic yield and safety of paediatric endoscopy performed by adult gastroenterologists in a Nigerian tertiary health facility. Materials and Methods: It was a retrospective study that evaluated the records of paediatric (≤18 years old) endoscopies carried out in the endoscopy suite of Obafemi Awolowo University Teaching Hospital Complex Ile-Ife, Nigeria from January 2007 to December 2014. Results: A total of 63 procedures were successfully completed in children of whom 4 were repeat procedures which were excluded. Thus, 59 endoscopies performed on children were analysed. Most (49; 83.1%) of these procedures on the children were diagnostic with oesophagogastroduodenoscopy being the commonest (43; 72.9%). Epigastric pain (22; 37.3%), haematemesis (17; 28.8%) and dysphagia (9; 15.3%) were the predominant indication for upper gastrointestinal (GI) endoscopy while haematochezia (9; 15.3%) and rectal protrusion (2; 3.4%) were the indications for colonoscopy. Injection sclerotherapy (3; 5.1%) and variceal banding (2; 3.4%) were the therapeutic upper GI endoscopic procedures conducted while polypectomies were performed during colonoscopy in 5 children (8.5%). Abnormal endoscopy findings were observed in 53 out of the 59 children making the positive diagnostic yield to be 89.8%. No complication, either from the procedure or anaesthesia was observed. Conclusion: Paediatric endoscopy performed by adult gastroenterologists is useful, feasible and safe. It is being encouraged as a viable option to fill the gap created by dearth of skilled paediatric gastroenterologists.

Childhood intussusception in Ile-ife: what has changed?

Background: Intussusception is one of the most common causes of intestinal obstruction in children. While the outcome has improved in the developed nations, the same cannot be said of the developing countries, more especially in the sub-Saharan region. This study aims to review our current experience in the management of childhood intussusception and factors affecting surgical outcome at the Obafemi Awolowo University Teaching Hospitals Complex Ile-Ife. Patients and Methods: This was a retrospective study of 78 patients treated for intussusception at paediatric surgical unit of Obafemi Awolowo University Teaching Hospitals Complex Ile-Ife between January 1993 and December 2011. The case notes of the patients were retrieved and the following information was recorded: Demographic characteristics, month of occurrence, clinical presentation, investigations, and management as well as the post-operative outcome. The patients were divided into two groups in terms of outcome. Results: There were 58 males and 20 females (M:F = 2.9-1). The age of most of the patients was between 3 months and 9 months with peak incidence at 6 months. Most patients 46 (58.9%) were seen during the dry season of December to April. Only six patients (7.7%) presented within 24 hours of onset of illness. More than half of the patients presented after 24 hours. Passage of red currant stool, vomiting, abdominal pain, fever, and abdominal distension, passage of watery stool, anal protrusion and palpable abdominal mass in various combinations were the clinical features. All the patients had surgical operations. The most common type of intussusception was ileo-colic type in 64 patients (82.1%). Intestinal resection rate was 41%. The overall mortality rate was 15.4%. Conclusion: There was a delay in presentation of children with intussusception with high post-operative mortality.

Ten-year experience with the Swenson procedure in Nigerian children with Hirschsprung’s disease

BACKGROUND Hirschsprungs disease (HD) is a common cause of intestinal obstruction in children. Definitive treatments consist of excision of the aganglionic segment and anastomosing the normal colon to the anal remnant. The outcome of this approach in Nigerian children is not known. The aim of this study was to analyze the short to mid-term outcome of children who have undergone the Swenson Procedure (SPT) as a treatment of HD over a period of 10 years. PATIENTS AND METHODS The clinical data of biopsy-proven cases of HD managed at the Obafemi Awolowo University Teaching Hospital, Ile-Ife, Nigeria, between 1998 and 2007 were reviewed. RESULTS There were 33 children 28 were males and five were females (M 5.6: F = 1). The median age at presentation was eight months (range three days to 11 years). Eighteen (54.5%) patients had primary pull-through without colostomy while 15 (45.5%) patients had a two-staged operation. The operation was carried out at a median age of 14 months with a range of seven weeks to 11 years, four months. Twenty-one (64%) of the patients were older than one year at the time of surgery. The level of aganglionosis was in the recto-sigmoid area in 30 (91%) patients. The commonest post-SPT complication was intestinal obstruction from adhesions. Bowel opening varied from once daily to eight times daily, median thrice daily. CONCLUSION The Swensons Procedure is an effective procedure in the treatment of HD in children in Ile Ife, Nigeria.

Posterior Urethral Valves in Children: Pattern of Presentation and Outcome of Initial Treatment in Ile-Ife, Nigeria.

Background: The management of posterior urethral valves (PUV) and its sequelae is still a challenge to most pediatric surgeons in our environment due to late presentation and inadequate facilities for long-term evaluation and treatment. Despite initial successful treatment about 40% would develop chronic renal failure. The aim is to describe the presentation, management and outcome of the initial treatment in boys with PUV. Materials and Methods: It is a retrospective analysis of PUV in boys 8 years and below over a 17 years period. Demographic characteristics, clinical features, investigations, and treatment outcome were reviewed. Results: Thirty-seven cases were analyzed. The median age was 5 months (range from birth to 8 years). Three (8.1%) patients had prenatal ultrasound diagnosis. The most common presentation was voiding dysfunction 37 (100%). Part of the preoperative investigation included micturating cystourethrogram (n = 31: 83.8%) and abdomino-pelvic ultrasonography (n = 37:(100%). The mean serum creatinine value of those who presented within thefirst 30 days of life and those who presented afterwards were 325 (±251) µmol/L and 141 (±100) µmol/L respectively, P = 0.003. Surgical interventions included trans-vesical excision of valves (n = 9: 28.1%), valvotomy (n = 10: 31.3%), balloon avulsion (n = 8: 25.0%), vesicostomy (n = 4: 12.5%) and endoscopic valve avulsion (n = 1: 3.1%). Seventeen (56.7%) patients had serum creatinine >70.4 µmol/L after 1-month of valve excision. Five (13.5%) patients had postrelief complications and 5 (13.5%) died on admission. Ninety percentage (27/30) of patients had poor prognostic indices. Conclusions: The initial treatment outcome was good but most had poor prognostic factors.

Groin exploration for the nonpalpable testes: A single center experience

Background: Management of non-palpable testes in Nigeria can be difficult due to late presentation and poor resources. Surgical exploration is often required for diagnosis and treatment. Aim: This study reviews the management outcome of clinically non-palpable testeis in a tertiary center in Nigeria. Materials and Methods: Ten years retrospective review of all clinically non-palpable testes in children aged 2-15years managed at the Obafemi Awolowo University Teaching Hospitals Complex Ile-Ife Nigeria. Results: Thirty two children with 44 testicular units were managed. The right side was involved in 12 (37.5%); left in 8 (25.0%) and bilateral in 12 (37.5%) patients. Pre-operative ultrasound was done in 12 patients with localization in just 4 patients (33.3% success rate).At groin exploration, 34 (77.32%) testicular units were located in the inguinal canal. Eight patients with 10 The remaining 10 (22.7%) testicular units required additional mini-laparotomy for which six (13.6%) and 4 (9.1%) testicular units respectively were either in the retroperitoneum or not found. Of the testes in the groin, twenty two (64.7%) testicular units were normal while 12 (35.3%) were atrophic. Four of the retroperitoneal testes were normal while 2 were atrophic. Eight (22.5%) testicular units among the inguinal group had multi-staged orchidopexy; while 2 each of the retroperitoneal group had orchidectomy,one stage orchidopexy, two staged Fowler Stephens (F-S) procedure or lost to follow up after first stage of F-S procedure. Mean follow up period was 2 months. 2 testicular units each had retracted or vanished respectively during follow up. Conclusion: Groin exploration still offers a viable approach Surgical exploration is still useful in to the management of non-palpable testes in low resource environment despite the lack of laparoscopy.

Situs inversus in association with duodenal atresia.

Situs inversus in association with duodenal atresia is very rare. A high index of suspicion coupled with appropriate evaluation is necessary for diagnosis and operative planning. We report a case of a 5-day-old who presented with duodenal atresia associated with polysplenia and situs inversus with a review of the medical literature.

A 10-year retrospective review of perioperative mortality in pediatric general surgery at Ile-Ife Hospital, Nigeria

BACKGROUND/PURPOSE The analysis of perioperative mortality as well as surgery- and anesthesia-related death in pediatric patients may serve as a potential tool to improve outcome. The aim of this study is to report the 24-h and 30-day overall, and surgery and anesthesia-related, mortality in a tertiary hospital. METHODS This is a retrospective review of perioperative mortality in children ≤15years at a general pediatric surgery unit. All pediatric general surgery cases operated under general anesthesia between January 2007 and December 2016 were included in the study and data analyzed. RESULTS A total of 4108 surgical procedures were performed in 4040 patients. The age was 1day to 15years with a median age of 2years. The all cause 24-h mortality was 34 per 10,000 procedures and the all cause 30-day mortality was 156 per 10,000 procedures. Septicemia was the most common cause of death. The determinants of mortality were neonatal age group (Adjusted Odd Ratio (AOR)=0.033, 95% CI=0.015-0.070, p=0.001), emergency surgery (AOR=90.91, 95% CI=27.78-333.33, p=0.001), higher ASA status (AOR=0.014, 95% CI=0.005-0.041, p=0.001) and multiple operative procedures (AOR=38.46, 95% CI=10.64-142.85, p=0.001). CONCLUSIONS Neonatal age group, children with poorer ASA status, emergency and multiple surgeries were predictors of perioperative mortality. LEVEL OF EVIDENCE Retrospective study.
