Predictive value of C-reactive protein, ultrasound and Alvarado score in acute appendicitis: a prospective pediatric cohort.

PURPOSE: To evaluate whether C-reactive protein (CRP) level and ultrasound (US) results on admission could aid the diagnostic accuracy of Alvarado score. METHODS: A prospective study was performed on children <14 years admitted for suspected acute appendicitis. Patients were categorized into three groups based on the Alvarado score: group I: score 7-10, group II: score 5-6, group III: score 0-4. RESULTS: The difference between predictive values of Alvarado score alone and Alvarado score with CRP was not statically significant. The PPV increased from 74.29% (Alvarado score and CRP) to 93.75% (Alvarado score and US) in group 1 (P = .001) and the NPV increased from 64.86 and 79.69% (Alvarado score and CRP) to 82.6 and 88.2% (Alvarado score and US) in group 2 (P = .01) and group 3 (P = .001), respectively. CONCLUSIONS: Alvarado score and ultrasound taken together improve the predictive value of diagnosing acute appendicitis in children.

Single port laparoscopic orchidopexy in children using surgical glove port and conventional rigid instruments

PURPOSE: We review the literature and describe our technique for laparoendoscopic single-site orchidopexy using a glove port and rigid instruments. We assessed the feasibility and outcomes of this procedure. MATERIALS AND METHODS: We retrospectively reviewed the case records of all children who had undergone laparoendoscopic single-site orchidopexy by use of a surgical glove port and conventional rigid instruments for a nonpalpable intraabdominal testis between January 2013 and September 2014. RESULTS: Data from a total of 20 patients were collected. The patients' mean age was 18 months. All cases had a nonpalpable unilateral undescended testis. Fourteen patients (70%) had an undescended testis on the right side and six patients (30%) had an undescended testis on the left side. Seventeen patients underwent primary orchidopexy. Three patients underwent single-port laparoscopic Fowler-Stephens orchidopexy for the first and the second stage. Average operating time was 57 minutes (range, 40 to 80 minutes). No patient was lost to follow-up. At follow-up, 2 testes were found to have retracted out of the scrotum and these were successfully dealt with in a second operation. One testis was hypoplastic in the scrotal pouch. There were no signs of umbilical hernia. CONCLUSIONS: Single-port laparoscopic orchidopexy using a glove port and rigid instruments is technically feasible and safe for various nonpalpable intraabdominal testes. However, surgical experience and long-term follow-up are needed to confirm the superiority of this technique.
