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.

Duplication cyst of ascending colon presenting as an ileal volvulus in a child: a case report and review of literature.

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.

Non-trauma related paediatric abdominal surgical emergencies in Lagos, Nigeria: Epidemiology and indicators of survival.

BACKGROUND: Pediatric surgical emergencies are associated with higher morbidity and mortality. The aim of this study is to describe the epidemiology of non-trauma related pediatric abdominal surgical emergencies in our centre and determine the indicators for survival in a cohort of patients. PATIENTS AND METHODS: A retrospective study of children aged 1 day to 15 years who presented with non-trauma related abdominal emergencies at the Lagos University Teaching Hospital (LUTH). RESULTS: There were 129 children. The median age at presentation was 5 months (range: 1 day-15 years). There were 104 males and 25 females. Sixty-four (49.6%) patients presented within 48 hours of the onset of the symptoms while 65 (50.4%) presented after 48 hours. Intestinal obstruction is the commonest indication for pediatric emergency surgery in our centre accounting for 76 patients (58.9%). Appendicitis is the second most common indication for emergency surgery with 13 patients (10.1%). Thirteen patients (10.1%) had postoperative complications. There were 13 deaths in all (10.1% mortality rate). Eleven out of 43 (25.6%) neonates died compared with 2 (2.3%) out of 86 patients in the other age groups (P=0.002). Seven out of 107 (6.5%) patients that had surgery within 72 hours died while 5/22 (22.7%) patients died who had surgery after 72 hours (P=0.003). There were 4 mortalities (28.6%) among patients with postoperative complications compared with 9 (7.8%) mortalities among 116 patients without any postoperative complications (Pp=0.001). CONCLUSION: Intestinal obstruction is the commonest pediatric surgical emergency seen in LUTH. Neonatal age, admission to surgery intervention time >72 hours, and severe postoperative complications are associated with high mortality.
