Nonspecific abdominal pain is a safe diagnosis.

AIM: The aim of this study is to assess if a clinical diagnosis of nonspecific abdominal pain (NSAP) is safe and if patients with this initial diagnosis are likely to require further investigation or surgical intervention. METHODS: 3323 patients admitted with NSAP from July 1990 to September 2012 utilizing a prospective database of all surgical admissions were included. Readmission over the period of the study and specifically within 30 days of their initial presentation was identified together with any invasive investigation or surgical intervention. MAIN RESULTS: 319 children (9.6%) were subsequently readmitted with abdominal pain at some point during the study period. Of these, 78 (2.3%) were readmitted within 30 days. 118 (3.5%) children subsequently had an operation or invasive investigation some point following their initial admission. Of these 33 (0.6%) had the procedure within 3 months of the initial admission. 13 patients had an appendicectomy within 3 months of the initial presentation. Of these histology confirmed appendicitis in 8 patients. This gives an overall incidence of "missed" appendicitis of 0.2 % (8/3323). CONCLUSION: This study confirms that a clinical diagnosis of nonspecific abdominal pain (NSAP) is safe in a pediatric population and the risk of "missing" appendicitis is only 0.2%. Patients and/or parents can be confidently reassured that the risk of missing organic pathology is very low.

Choledochal malformations: the Scottish experience.

INTRODUCTION: Excisional surgery for choledochal malformations in Scotland is currently performed in three specialist pediatric surgical centers using open or laparoscopic-assisted techniques. We reviewed the outcome of children who had excisional surgery in Scotland between 1992 and 2010. MATERIALS AND METHODS: Case notes for all patients undergoing excisional surgery in any of the three specialist pediatric surgical centers in Scotland between 1992 and 2010 were retrospectively reviewed. RESULTS: A total of 25 patients were identified, with a female preponderance of 4:1. Of these, three patients (12%) were diagnosed by antenatal ultrasound scan. The commonest presenting symptoms were anorexia (56%), abdominal pain (52%), and jaundice (52%). Only 20% had the classical triad of abdominal pain, jaundice, and a palpable mass. Using the King's College Hospital classification, 14 patients had type 1 malformations, 8 had type 4 malformations, and 3 had type 2 malformations. Median age at operation was 2 years (range 35 days to 13.5 years). Two centers performed open excision while the third center used primarily a laparoscopic-assisted technique. Median follow-up was 2.1 years (range 30 days to 11.9 years). Three patients (12%) required repeat laparotomy. The wound infection rate was 8% (n=2). The recurrent cholangitis rate was 8% (n=2). There was one late death due to adhesive small bowel obstruction, 4 years after surgery. To date, no patient has developed biliary tree stones or liver failure. CONCLUSIONS: Choledochal malformation excisional surgery, either open or laparoscopic assisted, can be safely performed in appropriately equipped, pediatric surgical centers in Scotland by experienced pediatric surgeons.
