ABSTRACT
Background: Fistula-in-ano treatment has remained quite challenging with high failure rates and a potential for damage to the anal sphincteric complex leading to flatal or faecal incontinence. The treatment of fistula-in-ano using the fistula laser closure (FiLaC) as a minimally invasive, sphincter-saving procedure for complex disease has recently been documented. Objectives: This review aimed to report the outcome of using it at the Lagos University Teaching Hospital. Patients and Methods: The procedures were performed with a radially emitting laser fibre from Biolitec AG-CeramOptec (Bonn, Germany). The duration of symptoms, type of fistula, duration of the procedures, and postoperative complications were evaluated. Results: Eleven male patients had laser fistula-in-ano closure. The age range was 33-51 years, with a median age of 39 years and an interquartile range (IQR) of 37-47 years. Five patients were noted to have high fistula/e, whereas six had low fistula/e, seven had a single tract each, and three had three tracts each. The duration of surgery ranged, approximately from 3 to 60 min, with a median of 19 min and IQR of 9-33 min. Postoperative pain was mild in all patients and were all discharged as day case. There was no postoperative wound infection, anal incontinence, anal stenosis, and subcutaneous abscess. However, there was a recurrence in two patients. Conclusions: FiLaC has been demonstrated to be a reliable and safe sphincter-saving procedure for treating fistula-in-ano even for complex and high fistulae that is feasible in our subregion.
ABSTRACT
Background: Haemorrhoids are the most common condition of the anal canal causing significant disability. Traditional excisional haemorrhoidectomy and its various modifications, while effective, may be attended by severe postoperative pain and other complications. Laser haemorrhoidoplasty is reported to be effective with fewer complications and shorter hospital stay. Objectives: The aim of this study was to report the outcome of intrahaemorrhoidal coagulation with 1470-nm diode laser at the Lagos University Teaching Hospital. Patients and Methods: The procedures were performed with a radially emitting laser fibre from Biolitec AG-CeramOptec (Bonn, Germany). The duration of symptoms, grade of the haemorrhoids, duration of the procedures, and postoperative complications were evaluated. Results: Eleven patients had laser haemorrhoidoplasty. There were seven males and four females. The age range was 23-71 years, with a median age of 47 years and an interquartile range (IQR) of 28-57 years. Duration of surgery ranged from 20 to 90 min, with a median of 33 min and IQR of 25-53 min. Postoperative pain was mild in eight patients and moderate in three. Ten patients were discharged as day cases and one 3 days later due to spinal anaesthesia-related headache and acute urinary retention. One patient later had an anal ulcer probably due to too much energy delivered during the procedure, this was managed conservatively. There was no postoperative wound infection, anal incontinence, anal stenosis, subcutaneous abscess, and fistula or recurrence. Conclusion: The advantages of laser haemorrhoidoplasty make it a readily acceptable form of treatment for haemorrhoids in our setting.
ABSTRACT
Biliary atresia (BA) is a rare disease characterised by biliary obstruction of unknown origin that presents in the neonatal period. It is classified into syndromic with various congenital anomalies and non-syndromic (isolated anomaly). We present a case of syndromic BA associated with polysplenia and intestinal malrotation, discovered incidentally during the Kasai procedure. The small intestine was found to be non-rotated with the duodenojejunal junction to the right of the vertebral column. The presence of accessory spleens was noted. Kasai portoenterostomy and Ladd's procedure were performed. The patient had an uneventful postoperative course with the passage of cholic stool from the third postoperative day. At the seventh-month follow-up, the stool remained cholic. A multidisciplinary approach in the care of babies with BA and long-term follow-up is crucial for a successful outcome.
ABSTRACT
Cysts of the prepuce are rare, and documented reports from the English literature are mostly from Asia. Presentations in children are worrisome to the parents. We report a case of a preputial cyst occurring in a neonate who was brought to our facility due to parental anxiety. After a thorough clinical evaluation, a freehand circumcision technique was performed which allowed exposure of the full extent of the cyst, the external urethral meatus and the glans, thus ensuring complete excision and minimising the risk of injury to the adjoining structures. We postulate that preputial cysts are rare in Africa due to the universality of circumcision, which is one of the options of treatment. Preputial cysts are benign foreskin cystic lesions that can be effectively treated with circumcision. This is probably the first reported case of a benign epithelioid preputial cyst from Africa. The paucity of reported cases may be due to the universal practice of circumcision in most of Africa.

INTRODUCTION: The Surgeons OverSeas Assessment of Surgical Needs (SOSAS) survey tool is used to determine the unmet surgical needs in the community and has been validated in several countries. A major weakness is the absence of an objective assessment to verify patient-reported surgically treatable conditions. The goal of this study was to determine whether a picture portfolio, a tool previously shown to improve parental recognition of their child's congenital deformity, could improve the accuracy of the SOSAS tool by how it compares with physical examination. This study focused on children as many surgical conditions in them require prompt treatment but are often not promptly diagnosed. METHODS: We conducted a descriptive cross-sectional community-based study to determine the prevalence of congenital and acquired surgical conditions among children and adults in a mixed rural-urban area of Lagos, Southwest Nigeria. The picture portfolio was administered only to children and the surgical conditions to be assessed were predetermined using an e-Delphi process among pediatric surgeons. The modified The Surgeons OverSeas Assessment of Surgical Needs-Nigeria Survey Tool (SOSAS-NST) was administered to household members to collect other relevant data. Data were analyzed using the REDCap analytic tool. RESULTS: Eight hundred and fifty-six households were surveyed. There were 1984 adults (49.5%) and 2027 children (50.5%). Thirty-six children met the predetermined criteria for the picture portfolio-hydrocephalus (n = 1); lymphatic malformation (n = 1); umbilical hernia (n = 14); Hydrocele (n = 5); inguinal hernia (n = 10) and undescended testes (n = 5). The picture portfolio predicted all correctly except a case of undescended testis that was mistaken for a hernia. The sensitivity of the picture portfolio was therefore 35/36 or 97.2%. CONCLUSIONS: The SOSAS-NST has improved on the original SOSAS tool and within the limits of the small numbers, the picture portfolio has a high accuracy in predicting diagnosis in children in lieu of physical examination.

Background: Male circumcision is the most common surgical procedure worldwide and is often carried out for religious, cultural, medical and public health reasons. It is commonly performed during the neonatal period. Many studies have now shown that pain is a common intra- and post-operative complication. To ensure proper analgesia during the procedure, many surgeons opt for the use of pacifiers as an adjunct to anaesthesia during neonatal circumcision. The aim of this study is to compare nutritive pacifiers (NPs) versus non-NPs (NNPs) as adjuncts to local anaesthesia in male neonatal circumcision using the Plastibell technique. Methods: A prospective randomised controlled study was carried out between October 2019 and March 2020. A total of 100 neonates were circumcised using the Plastibell technique and randomised into NP (Group A, n = 33), NNP (Group B, n = 33) and controls (Group C, n = 34), respectively. The differences in pain scores using the Neonatal Infant Pain Scale, total crying time and heart rate during circumcision were recorded and assessed. Results: The age of participants ranged from 5 to 28 days and the weight ranged from 2.5 to 5.0 kg. The overall mean age, birth weight and current weight of the participants were 15.5 ± 6.1 days, 3.4 ± 0.4 kg and 3.5 ± 0.6 kg, respectively. The control group had the highest average pain score of 5.5 (4.5-5.8) compared to the intervention groups with median pain score (NP: 3.3 [1.3-4.3] and (NNP: 4.3 [3.1-5.1], respectively). NPs had significantly lower pain scores (P = 0.023) and reduced total crying time (P = 0.019) at all stages of the circumcision compared to those given NNPs and controls. Conclusion: This study showed that NPs were superior to NNPs in providing additional pain control during male neonatal circumcision.

Background: The impact of the corona virus disease 2019 (COVID-19) pandemic on global health, has reached far beyond that caused by the disease itself. With ongoing mutations and the emergence of new strains of the virus alongside repeated waves of the pandemic, the full impact of the pandemic is still evolving and remains difficult to predict or evaluate. In paediatric surgery, it has led to significant disruptions in patient care, the extent and consequence of which are not fully documented in Nigeria. Aim: This study aims to evaluate the impact of COVID-19 on services, training and research in a busy paediatric surgery unit during the initial 3-month period of the COVID-19 pandemic lockdown. Methods: This study was an ambispective evaluation of the preceding 3 months before lockdown and the initial 3 months of lockdown. Clinic cancellations, elective and emergency surgeries, delays in access, extra cost of care to patients, impact on training and research, and the psychologic impact of the pandemic on staff and guardians were evaluated. Results: During the 3-month lockdown period, an estimated 78 new cases and 637 follow-up cases could not access care. Ninety-seven elective surgeries in 91 patients were postponed. Two (2.2%) patients' symptoms progressed. All emergency patients received care. Out-of-pocket expenditure increased averagely by $124. The pandemic contributed to delays in seeking (13%), reaching (20%) and receiving care (6%). Trainee participation in surgeries was reduced and academic programmes were suspended. Five staff were exposed to the virus and 3 infected. Conclusion: Paediatric surgery has been negatively impacted by COVID-19. Efforts must focus on planning and implementing interventions to mitigate the long-term impact.

The use of reverse transcription-polymerase chain reaction (RT-PCR) is the gold standard laboratory test for diagnosing SARS-CoV-2 infection. However, it has the disadvantage of a long turnaround time and cost. The Nigeria Centre for Disease Control (NCDC) formulated a case definition for COVID-19. We sought to determine the utility of a 14-item, point-weighted clinical screening questionnaire adapted from the NCDC case definition in identifying patients more likely to have the disease. This was to aid prompt clinical decision-making. Methods: We retrospectively reviewed the data of 113 non-surgical patients presenting to the Accident and Emergency Department (A and E) of Lagos University Teaching Hospital, Lagos, Nigeria. Patients were stratified based on screening scores into low (0-2), moderate (3-5) and high (6) pre-test categories. Patients with low and high scores ≥6 were admitted to the A and E and the COVID-19 holding ward, respectively, while the moderate group had chest computed tomography scans to aid further decision-making, pending the outcome of their RT-PCR results. The validity of the triage score as compared to the RT-PCR test result was calculated and the kappa score of agreement was utilised to evaluate the concordance between two triage scores. The optimum cut-off score was also obtained based on the maximal Younden's index. Results: The frequencies of low, moderate and high pre-test scores were 34 (30%), 43 (38.1%) and 36 (31.9%), respectively. Overall, 38.1% (43/113) were RT-PCR positive. RT-PCR was positive in 26.5% (9/34) with low screening scores, 55.8% (24/43) with moderate scores and 27.8% (10/36) with high scores. The sensitivity and specificity of a high score of 6 were 25% and 92.86%, while the lower score of 3 had sensitivity and specificity of 62.5% and 58.6%, respectively. Conclusion: The screening tool showed a high specificity in its initial design, which suggests that anyone with a low score using this tool has a high probability of testing negative. We recommend a cut-off score of 4 (score A) or 6 (score B) of the current screening tool be used to increase the chances of identifying persons with COVID-19 for RT-PCR testing.

BACKGROUND: Over the last two decades, there has been significant improvement in the outcomes of children with Wilms' tumour (WT) in high income countries (HICs) with approximately 85% survival rate globally. This is partly attributable to a multi-disciplinary team approach to care and the evolution of more robust treatment measures. A previous review in our centre prior to multi-disciplinary team shows a survival rate of 31.48%, However, the survival rates from low- and middle-income countries are still low when compared to HICs due to delays in access to care at all levels, poor to non-existent health insurance coverage, limited workforce resources, weak health-care systems and infrastructure. The aim of this study is to determine the impact of a multi-disciplinary team approach on the treatment outcomes of children with WT. METHODOLOGY: This is a 5-year retrospective review of all patients managed with WT at the Lagos University Teaching Hospital, Lagos, Nigeria. Information was extracted from the patients' case notes, operation notes and ward admission records. The data were analysed with SPSS 25, and P < 0.05 was considered to be statistically significant. RESULTS: Forty patients were included in the study; male to female ratio was 1.6:1. The disease occurred in the right kidney in 23 patients (57.5%) and on the left in 17 patients (42.5%). The average duration of symptoms before presentation was 3.6 months (range 1-7 months), majority of patients presented with abdominal masses and were assessed as per unit protocol with abdominal Computerized tomography scan, chest X-ray and abdominal ultrasound scan to assign the patient International Society of Paediatric oncology regimen. The predominant stage at surgery was Stage III 26 (65%), while Stage IV was 9 (22.5%). Morbidity after chemotherapy was 10 (25%). Twenty-five patients (63%) completed chemotherapy while 15 patients (37%) started chemotherapy but defaulted midway. The 5-year survival rate was 75%. Increasing age and male sex were associated with reduced odds of mortality; however, this was not statistically significant. Increased duration of treatment, being treated with chemotherapy alone, as well as advanced tumour stage and histology were associated with increased odds of mortality, however, this was not statistically significant. CONCLUSION: The development of an institutional WT treatment pathway involving a multidisciplinary team has resulted in improved outcomes. There is need for increased community awareness to improve the time to presentation.

BACKGROUND: COVID-19 pandemic has affected surgical practice worldwide. Laparoscopic procedures utilizing gas for pneumoperitoneum require specific consideration. METHOD: A panel of experts of the Laparoscopic Surgery Society of Nigeria (LASSON) was constituted to draft recommendations on the conduct of minimal access surgical (MAS) procedures during and after the pandemic in Nigeria. RESULTS: The Society strongly believes that laparoscopy and other (MAS) procedures can be safely performed during and after the current COVID-19 pandemic if appropriate safety measures are adhered to. The Society therefore makes the following recommendations for all units performing MAS in Nigeria: (1) Design clear cut measures to navigate the pandemic in each hospital. (2) Triage surgical services and procedures. (3) Encourage screening and testing of all patients (4) Provide adequate patient communication and consenting (5) Ensure compulsory use of Personal Protective Equipments (PPEs) (6) Minimize preoperative and intraoperative personnel (7) Envisage postoperative respiratory challenges and make adequate preparation for respiratory support: (8) Make specific considerations for the confirmed COVID 19 positive patients:(9) Private facilities offering MAS and endoscopic procedures should take special measures during the pandemic (10) Know your limits. CONCLUSION: The Society encourages all MAS practitioners to adhere to these recommendations.
ABSTRACT
Hirschsprung's disease is a relatively common disease in pediatric colorectal surgery. The treatment modalities have evolved from third-stage to single-stage in the past three decades. The single-stage procedure can be performed using the open, transanal or laparoscopy-assisted techniques. We use these cases to illustrate the first laparoscopically assisted procedures for Hirschsprung's disease in our center. The laparoscopic-assisted technique is described, and lessons in collaboration across institutions and within institutions are discussed.
ABSTRACT
BACKGROUND: The practice of laparoscopy involves the use of training models that are different from conventional open surgery. These concepts are not captured in the traditional models of surgical residency training. Residency training in surgery has been seen as an ample opportunity for early introduction and training in laparoscopy. OBJECTIVES: This study aimed to assess the level of exposure and training experience of some surgical resident doctors in accredited training institutions in Nigeria on laparoscopy. METHODOLOGY: A cross-sectional survey was conducted among the resident doctors undergoing revision course in surgery at the National Orthopaedic Hospital, Igbobi, Lagos, and Lagos University Teaching Hospital, Lagos, in March 2018. Using the quantitative method of data collection, a pre-tested structured questionnaire was used to collect information on the demography and training exposure of the residents in laparoscopy. RESULTS: A total of 54 of 96 residents surveyed returned the questionnaire, giving a response rate of 56%. There were 53 (98.1%) males and 1 (1.9%) female. The age range of the respondents was between 30 and 46 years, with a mean of 34.2 ± 3.96 years. Thirty-two (59.3%) respondents had spent at least 2 years training in surgery. Thirty-six (66.7%) respondents had not participated in more than four laparoscopic procedures during their rotation. Forty-six percent of respondents reported that their experience in laparoscopy was mainly by observation of the procedures. Forty-nine (90.7%) of respondents surveyed had not attended any training program in laparoscopy. Eighty-one (81.0%) of respondents had a strong motivation and desire for future practice of laparoscopy. CONCLUSION: This study revealed that few Nigerian postgraduate trainees sampled in the survey were exposed and had training experience in laparoscopy.
ABSTRACT
BACKGROUND: In many low- and middle-income countries, data on the prevalence of surgical diseases have been derived primarily from hospital-based studies, which may lead to an underestimation of disease burden within the community. Community-based prevalence studies may provide better estimates of surgical need to enable proper resource allocation and prioritization of needs. This study aims to assess the prevalence of common surgical conditions among children in a diverse rural and urban population in Nigeria. METHODS: Descriptive cross-sectional, community-based study to determine the prevalence of congenital and acquired surgical conditions among children in a diverse rural-urban area of Nigeria was conducted. Households, defined as one or more persons 'who eat from the same pot' or slept under the same roof the night before the interview, were randomized for inclusion in the study. Data was collected using an adapted and modified version of the interviewer-administered questionnaire-Surgeons OverSeas Assessment of Surgical Need (SOSAS) survey tool and analysed using the REDCap web-based analytic application. MAIN RESULTS: Eight-hundred-and-fifty-six households were surveyed, comprising 1,883 children. Eighty-one conditions were identified, the most common being umbilical hernias (20), inguinal hernias (13), and wound injuries to the extremities (9). The prevalence per 10,000 children was 85 for umbilical hernias (95% CI: 47, 123), and 61 for inguinal hernias (95% CI: 34, 88). The prevalence of hydroceles and undescended testes was comparable at 22 and 26 per 10,000 children, respectively. Children with surgical conditions had similar sociodemographic characteristics to healthy children in the study population. CONCLUSION: The most common congenital surgical conditions in our setting were umbilical hernias, while injuries were the most common acquired conditions. From our study, it is estimated that there will be about 2.9 million children with surgically correctable conditions in the nation. This suggests an acute need for training more paediatric surgeons.

BACKGROUND: The use of honey as an escharotic agent in the conservative management of omphalocele major has not been widely explored in spite of its proven benefits in chronic wound management. We explored the use of local honey as an escharotic agent by comparing its use with 2.5% formal saline in the conservative management of major omphaloceles at the Lagos University Teaching Hospital, Lagos, Nigeria. METHODS: From January 2006 to December 2009, 43 consecutive newborns with intact omphalocele major were alternately assigned into either Honey (H) or formal saline (FS) group. The membrane cover of each omphalocele was painted with the allotted group agent once every 48 h. The occurrence of faecal fistulas, rupture of eschar, intestinal obstruction as well as the mean duration of full wound healing, infection rates and overall mortality rates were compiled for the two groups. RESULTS: Eighteen newborns were assigned to the FS group while 25 others were prospectively enrolled into the H group. The age, sex and weight of newborns in both groups at presentation were comparable. Three omphaloceles (16.7%) ruptured and eviscerated among the FS group during the study while 1 (4%) of these occurred in the H group. Four (22.2%) cases of faecal fistula occurred in the FS group while none was recorded in the H group. One (5.6%) patient in the FS group developed small bowel stricture. This was not recorded in the honey group. Overall, there were 8 (44.4%) complications in the FS group and 1 (4%) in the H group. There was no statistical difference between the two groups concerning the occurrence of fistulae, sac rupture or bowel stricture. However, overall number of complications was statistically more in the FS group when compared to the H group (P < 0.05). Wounds in the H group healed within a mean period of 34.4 ± 4.9 days while those in the FS group healed within a mean period of 45.7 ± 6.8 days P < 0.01). CONCLUSION: Honey is a good escharotics agent in the conservative management of major omphaloceles. Honey promotes faster healing and unlike 2.5% formal saline, is not significantly associated with faecal fistulas, rupture or bowel stricture.

AIMS: Hypospadias is a common congenital anomaly of the urethra and phallus, which is not life threatening. It is thus less prioritised in a resource-limited setting. The aim of this study was to evaluate the management of hypospadias by our paediatric surgery unit and determine the factors affecting the delay between presentation and surgical repair while proffering possible solutions to such delay in hypospadias repair surgery. PATIENTS AND METHODS: This was a retrospective review of all hypospadias repair surgeries carried out by our paediatric surgery unit over a 38-month period, evaluating the period between presentation and first surgery for each patient. Data were analysed using IBM SPSS Statistics for Windows, Version 20.0 (IBM Corp., Released 2011, Armonk, NY, USA). Chi-square test was used to compare categorical variables and P ≤ 0.05 was considered significant. RESULTS: In 38 months, 47 operations for hypospadias were carried out on 42 boys. Thirty-seven patients (88.1%) had >3 months delay to surgery. The most frequent contributory factor to delay was unavailable theatre space (13 patients, 31%). Surgical outcome was good in only 16 patients (44%). Of the 16 patients with good outcome, 10 (63%) were operated between the ages of 2-4 years (P > 0.05). CONCLUSIONS: Multiple factors are responsible for delays in carrying out hypospadias surgery in resource-limited environments, notably securing a functional operating theatre suite in the light of more urgent conditions. To combat these delays, we recommend having dedicated hypospadias repair sessions and surgeons dedicated to hypospadias repair. Hypospadias outreach camps are also proposed.

BACKGROUND: The use of ultrasonography in the pre-operative localisation of undescended testes has become controversial due to fears about its accuracy. This study was designed to ascertain the accuracy, sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of ultrasonography in the localisation of the undescended testes in children. PATIENTS AND METHODS: A prospective evaluation of all boys undergoing operation for undescended testes at the Lagos University Teaching Hospital, Idi-Araba, Lagos, over a 12 month period was performed. The pre-operative clinical and ultrasound findings were compared with the findings on surgical exploration. RESULTS: Forty boys with 52 undescended testes were studied. The mean age of the boys at the time of surgery was 4.0 ± 0 years (range 1-11 years). Forty-six (88.5%) testes were localised pre-operatively by ultrasound- 20 of 22 (90.9%) palpable testes and 26 of 30 (86.7%) non-palpable testes. Intra-operatively, 49 (94.2%) of the undescended testes were found while 3 (5.8%) were absent/vanishing testes. Ultrasound evaluation had an accuracy of 86.5%, sensitivity of 89.8%, and specificity of 33.3%, PPV of 95.7% and a NPV of 16.7%. CONCLUSION: Ultrasound assessment is beneficial in pre-operative evaluation of children with undescended testes.

Alimentary tract duplications are uncommon congenital anomalies that may be found anywhere along the gastrointestinal tract. They have a diverse presentation and often times present with complications of intestinal obstruction and/or lower gastrointestinal haemorrhage. We report a very rare finding of a colonic duplication cyst which presented as an ileal volvulus in a young girl. While available investigations were non-specific, the child survived on account of an early decision to operate. She had resection of the duplication cyst and ileo-colic anastomosis. She made good recovery post-operatively. A high index of suspicion is necessary on the part of clinicians to recognise this condition. Early operative intervention is necessary in the developing world setting where state of the art investigations are not available for accurate pre-operative diagnosis.

PURPOSE: To determine the ability to predict difficult visualization of the larynx (DVL) from the following preoperative airway predictive indices, in isolation and combination: modified Mallampati test (MMT), thyromental distance (TMD), sternomental distance (SMD), horizontal length of the mandible (HLM) and inter-incisor gap (IIG). METHODS: Three hundred and eighty consecutive patients undergoing general anesthesia were evaluated using the MMT, TMD, SMD, HLM and IIG and the cut-off points for the airway predictors were Mallampati III and IV; < or = 6.5 cm, < or = 13.5 cm, < or = 9.0 cm and < or = 4.0 cm respectively. During direct laryngoscopy, the laryngeal view was graded using the Cormack and Lehane (CL) classification. CL grades III and IV were considered difficult visualization. Sensitivity, specificity and positive predictive value for each airway predictor in isolation and in combination were determined. Logistic regression analysis was used to determine independent predictors of DVL. RESULTS: Difficulty to visualize the larynx was found in 13 (3.4%) patients. The sensitivity, specificity and the positive predictive value for the five airway predictors were: MMT (61.5%; 98.4%; 57.1%), TMD (15.4%; 98.1%; 22.2%), SMD (0%; 100%; 0%), HLM (30.8%, 76.0%; 4.3%) and IIG (30.8%; 97.3%; 28.6%). The best combination of predictors was MMT/TMD/IIG with a sensitivity, specificity and positive predictive value of 84.6%; 94.6%; 35.5% respectively. Logistic regression analysis showed that weight, MMT, IIG and TMD were independent predictors of DVL. CONCLUSION: MMT, TMD and IIG appear to provide the optimal combination in prediction of DVL in a West African population.
