Preoperative localization of undescended testes in children: Comparison of clinical examination and ultrasonography

BACKGROUND Preoperative localization of the testis aids effective management of undescended testes. Various diagnostic techniques have been applied in the localization of undescended testes with varying results. The aim of this study was to compare clinical assessment and ultrasound evaluation in the preoperative localization of undescended testes in children. METHODS A prospective evaluation of all boys undergoing operation for undescended testes at the Lagos University Teaching Hospital, Idi Araba, from July 2010 to June 2011 was carried out. The findings on preoperative clinical and ultrasound examinations were compared with intraoperative findings. RESULTS Forty boys with 52 undescended testes were studied. The median age of the boys at the time of surgery was 4 years (range 1-11 years). Forty-five testes (86.5%) were accurately localized preoperatively by ultrasound while 25 testes (48.1%) were accurately localized on clinical examination. Ultrasound evaluation had an accuracy of 86.5% in preoperative localization of undescended testes. Clinical examination had an accuracy of 48.1% in preoperative localization of undescended testes. Ultrasound was more accurate than physical examination (p < 0.001). CONCLUSIONS Ultrasonography is more accurate than clinical examination in the preoperative localization of undescended testes in children and could play a role in preoperative evaluation of patients with undescended testes.

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.

Diagnostic value of high resolution ultrasound in localisation of the undescended testis in children.

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.

Two-stage flap repair of severe hypospadias: Usefulness of the tubularized incised plate urethroplasty

PURPOSE The use of flaps in the two-stage repair of posterior hypospadias associated with severe chordee has been well established. Despite the almost certain guarantee of flap take, complications such as diverticuli are still relatively high. While different applications of the tubularized incised plate have been described, experience with the application of the technique to the two-stage flap repair is very limited. A previous local review of 15 cases performed at the present institution during the period 1998-2003, using the technique as described by Rekit, revealed fistulae and diverticulum rates of 20% and 27%, respectively. With the primary objective of improving surgical outcome, the midline incision was incorporated into the two-stage flap repair. MATERIALS AND METHODS Between 2004 and 2015, 35 boys (aged 2-15 years) with severe hypospadias that required excision of the urethral plate were operated using the two-stage flap technique. The first stage involved mobilization of preputeal or dorsal penile skin (if circumcised) to the ventral surface, as described by Retik. After a minimum interval of 6 months, the second-stage operation was performed in a way similar to the technique of tubularized incised plate urethroplasty, as popularized by Snodgrass, and involved a preliminary midline incision on the neo-urethral plate followed by tubularization and multilayered closure. RESULTS All but one flap took successfully. The outcome was satisfactory in 80% of patients, and there was a fistula rate of 14% ( Summary Table). One patient had a complete breakdown of the flap and was successfully treated about 12 months later by repeating the second stage of the operation. No case of diverticulum or stricture was recorded. DISCUSSION Even though there was a marginal improvement in the fistula rate, the most striking observation was the complete absence of diverticulum or stricture. With a reported incidence rate of 20-63%, different authors have reported diverticulum formation (despite the absence of distal obstruction) to be a major problem of the two-stage flap technique. Attempts by these authors at reducing the risk of diverticulum by reducing flap size have tended to increase the risk of strictures. This has been the main reason given by some authors for abandoning the technique. The main limitations of the present study included the wide age range of the patients and the small sample size. CONCLUSION The inclusion of a midline incision in a two-stage flap urethroplasty for proximal hypospadias appears to prevent the development of diverticulum.

Formal saline versus honey as escharotic in the conservative management of major omphaloceles

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.

Factors influencing waiting time in hypospadias repair surgery.

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.

A single-institution experience with hydrostatic reduction for childhood intussusception: A preliminary report

Background/purposeHydrostatic reduction for intussusception has the benefit of achieving reduction without the need for general anaesthesia or surgery and the possible attendant complications. This has made it the most popular interventional modality in many centres today. Hydrostatic reduction was added to our armamentarium in the treatment of childhood intussusception recently and this report represents our initial experience. MethodsThis study is a prospective review of all cases of intussusception that presented at the Emergency Department at the Lagos University Teaching Hospital between February 2012 and May 2014. Eligibility for hydrostatic reduction was based on internationally recognized criteria, which included absence of peritonitis and shock. Data were analyzed using the statistical package for social sciences (version 20). The &khgr;2-test was used to compare categorical variables, and a P value of 0.05 was considered significant. ResultsA total of 66 patients were seen within the study period. Thirty-eight were male (57.6%) and 28 were female (42.4%). The age range was 3–84 months and the mean age was 12.0±30.8 months. Twenty-six patients (39.4%) underwent hydrostatic reduction, of which 11 (42.3%) were successful. There was a correlation between the duration of symptoms and successful hydrostatic reduction (P<0.05), with five of the 11 (45.5%) presenting within 24 h of symptoms. ConclusionAlthough less than half of the patients presenting with childhood intussusception were eligible for hydrostatic reduction, the method remains a feasible option in our environment in spite of late presentation by most of our patients. The duration of presenting symptoms was the most important determinant of successful hydrostatic reduction.

Neonatal neuroblastoma with adrenal primary and metastasis to the liver: A case report and a review of literature

We report the case of a 23-day-old neonate with neuroblastoma (NBL) in the right adrenal gland and widespread metastases to the liver. This raises the possibility of foetal NBL, which was missed during periodic ultrasonography done during the mothers pregnancy. We hope that this report would increase the awareness of physicians about foetal, congenital and neonatal NBL; and of sonographers about space-occupying lesions in the foetus. The clinicopathologic features and the management of neonatal NBL are discussed.

Survey of teaching, research and conference experiences of paediatric surgical trainees in Nigeria

AIM To determine the teaching methods used by residents in paediatric surgery in Nigeria and their exposure to research and conferences. MATERIALS AND METHODS A structured questionnaire was administered to trainees in paediatric surgery in Nigeria seeking information regarding different teaching methods used, frequency of use, involvement in research and participation in conferences. RESULTS There were 11 respondents (91.6%) of 12 questionnaires that were distributed. All of them were training in accredited teaching hospitals in Nigeria. All of them had been involved in teaching medical students. Ten residents were involved in teaching in wards/bedside two times or more in a week and all were involved in teaching at the clinics. Only one resident used audiovisual aid at least once a week to teach students. Eight trainees used tutorial or seminar group discussion as a teaching tool once a week. Four trainees had not used written essay as a way of teaching students while five had never given students lectures in a classroom before. All the respondents had participated in retrospective research while nine had been involved in prospective research. Nine residents had attended conferences nationally while two had attended international conferences. Six trainees presented a paper or more at national conferences while one presented at an international conference. CONCLUSION Trainees in paediatric surgery in Nigeria are significantly involved in the teaching of undergraduate medical students and clinical research. This should be encouraged and further enhanced by motivating the trainees to attend international conferences.
