"Background Intussusception is a common cause of intestinal obstruction in young children. The diagnosis and treatment of intussusception has evolved over the years with ultrasound being the first choice imaging technique and a major player in the non-operative reduction of intussusception owing to its advantage of reduced morbidity and non-exposure to ionizing radiation when compared to other modalities of treatment.Aim & Objectives: The aim of this study was to evaluate the efficiency of ultrasound guided hydrostatic reduction in the management of intussusception in children and assess the predictors of reducibility.Methods: A prospective study of all infants and children who presented with uncomplicated intussusception was conducted between January, 2005 and September, 2013. The diagnosis of intussusception was made clinically and this was confirmed by an abdominal ultrasonography. Ultrasound guided hydrostatic reduction of intussusception was performed on the selected patients after they were adequately resuscitated. Failed was abandoned in favour of operative reduction in some patients. Data collected included the age of the patient, duration of symptoms and the outcomes of the procedure and these were analyzed. Results: Eighty-four patients with intussusception were treated over this period, 36(42,9%) patients were found suitable for hydrostatic reduction of intussusception. Twenty-four(66.7%) patients presented within 48 hours of onset of symptoms. Twenty-one(58.3%) patients had successful hydrostatic reduction of intussusceptions while 15 (41.7%) patients had failed reduction. The procedure was successful in majority (58%) of the patients age of 1 year and one of the three (33%) patients older than one year. Hydrostatic reduction of intussusceptions was successful in 14 out of 24 patients (58.3%) who presented within 48 hours of onset of symptoms. Conclusion: Hydrostatic reduction of intussusception under ultrasound guidance is an effective and use conservative method of management in carefidly selected children with intussusception. Overall, this modality treatment is cost effective and could readily be used for patients in resource poor environment. It also monitors the reduction process and visualizes the components of the intussusception including the lead points. "
Pattern and outcome of childhood intestinal obstruction at a Tertiary Hospital in Nigeria
(Faculty of Medicine, Makerere University, 2009) Ogundoyin, O. O.; Afolabi, A. O.; Ogunlana, D. I.; Lawal, T. A.; Yifieyeh, A. C.
Background: Intestinal obstruction is a common cause of pediatric surgical emergency with a high morbidity and mortality in Africa. Methods: A retrospective review of cases managed from January 1996 to December 2005 at a teaching hospital in Southwestern, Nigeria was done to examine the pattern of causes of intestinal obstruction in children and the management outcome. Results: One hundred and thirty cases were seen over the study period with an age range of 2 hours to 14 years. Majority (61.24%) were infants, while 18.46% were neonates. Fifty-five cases (42.31%) were due to congenital causes while the rest were of acquired causes. The major causes of intestinal obstruction in the study were intussusception (29.23%), anorectal malformations (22.31%), obstructed inguinoscrotal hernia (16.92%) and Hirschsprungís disease (13.85%). Surgical site infection and sepsis were the commonest complications observed with an overall complication rate of 60.78%. The mortality rate was 3.08% and most (75%) occurred in neonates. Conclusion: While mortality as an outcome of management is low, the morbidity was very high in this study.
Pediatric intussusception in Ibadan, South Western Nigeria
(Wolters Kluwer - Medknow, 2008) Ogundoyin, O. O.; Afolabi, A. O.; Lawal, T. A.
Background: Intussusception is the most common cause of acquired intestinal obstruction in children presenting commonly as a surgical emergency between the fifth and ninth months of life. Method: A retrospective review of cases seen over eight years in our hospital was done to study the pattern of presentation and factors influencing management in our environment. Results: Thirty four patients were managed with age ranging from one week to six years. Thirty patients (88.2%) were infants. Majority were boys (58.8%) and the most common symptoms were vomiting (94.1%), passage of red currant jelly stool (91.2%), excessive crying (58.8%) and fever (52.9%). All the patients had exploratory laparotomy done with half of them undergoing simple reduction of the intussusception. There were three mortalities, two of which presented very late after two weeks of onset of illness with septicemia. There was no recurrence. Conclusion: Late presentation is a major cause of morbidity and mortality in developing countries. Early presentation, aggressive resuscitation and non- operative treatment will help in reducing the high mortality associated with late presentation.
Predictors and outcome of acute kidney injury after non-cardiac paediatric surgery
(Springer Science+Business Media, 2019) Lawal, T. A.; Raji, Y. R.; Ajayi, S. O.; Ademola, A. D.; Ademola, A. F.; Ayandipo, O. O.; Adigun, T.; Ogundoyin, O. O.; Olulana, D. I.; Asinobi, A. O.; Salako, B. L.
Background: It is necessary to define the problem of acute kidney injury (AKI) after non-cardiac surgery in order to design interventions to prevent AKI. The study aimed to evaluate the occurrence, determinants and outcome of AKI among children undergoing general (non-cardiac) surgery. Methods: This was a prospective cohort study of patients aged ≤ 15 years who had general surgery over 18 months period at a tertiary hospital in Nigeria. AKI was evaluated at 6 and 24 h and within 7 days of surgery. Data were analysed using SPSS version 21. Results: A total of 93 patients were studied with age ranging from 3 days to 15 years (median = 4 years). AKI occurred within 24 h of surgery in 32 (34.4%) and cumulatively over 7 days in 33 (35.5%). Patients who had sepsis were nearly four times as likely as others to develop perioperative AKI (OR = 3.52, 95% CI 1.21, 10.20, p = 0.021). Crude mortality rate was 12.1% (4/33); no mortality was recorded among those without AKI, p = 0.014. Conclusion: Perioperative AKI occurred in 35.5% of children who underwent general (non-cardiac) surgery. Patients who had sepsis were four times more likely than others to develop AKI. Mortality was documented only in patients who had AKI.
Solitary colonic neurofibroma in an African child
(SpringerOpen, 2018) Ogundoyin, O. O.; Ajani, M. A.
Neurofibromas are a group of heterogeneous neurocutaneous disorders. They are benign neoplasms consisting of neural and connective tissue components affecting any organ system. Gastrointestinal involvement in neurofibromatosis type 1 (NF1) are rare and are late manifestations of the disease, but in exceptional cases they can be the initial sign of neurofibromatosis in patients who have no external stigmata that arouse suspicion. Neurofibromatosis of the colon as a part of the NF1 is rare. Isolated colonic neurofibromatosis without other features suggestive of NF1 is rarely encountered in clinical practice. We report the case of a 12-year-old boy with an isolated colonic neurofibromatosis presenting with a right hypochondrial mass with no external features of NF1. We report this case as its presentation in children may give a diagnostic dilemma and the probability of malignant digestive disease associated with NF1 should be kept in mind, regardless of the age of the patient.
