Postoperative pain is less intense after laparoscopic than after open surgery. However, minimally invasive surgery is not a a pain-free procedure. Many trials have been done in adults using intraperitoneal and/or incisional local anesthetic, but similar studies have not yet been reported in the literature in children. Aim: The aim of this study was to evaluate the analgesic effect of periportal infiltration and intraperitoneal instillation of ropivacaine in children undergoing laparoscopic surgery. Materials and Methods: Thirty patients who underwent laparoscopic surgery were randomly allocated to one of three groups. Group A ( n = 10) received local infiltration of port sites with 10 mL of ropivacaine. Group B ( n = 10) received both an infiltration of port sites with 10 mL of ropivacaine and an intraperitoneal instillation of 10 mL of ropivacaine. Group C did not receive any analgesic treatment. The local anesthetic was always administered at the end of surgery. The degree of postoperative abdominal parietal pain, abdominal visceral pain, and shoulder pain was assessed by using a Wong-Baker pain scale and a Visual Analog Scale (VAS) at 3, 6 12, and 24 hours postoperatively. The following parameters were also evaluated: rescue analgesic treatment, length of hospital stay, and time of return to normal activities. Results: Three hours after operation, patients had low pain scores. Six and 12 hours postoperatively, the abdominal parietal pain was significantly higher ( P < 0.0005) in group C than in the other two groups, both treated with an infiltration at the trocar sites; mean intensity of abdominal visceral pain was significantly lower ( P < 0.0005) in group B than in groups A and C; the overall incidence of shoulder pain was significantly lower ( P < 0.0005) in group B patients than in patients of groups A and C. At 20 hours postoperatively, pain scores were significantly reduced of intensity in all groups. Rescue analgesic treatment was significantly higher in group C, if compared to groups A and B 12 hours after the operation. No statistically significant difference was found in length of hospital stay, but children who received analgesic treatment had a more rapid return to normal activities than untreated patients ( P < 0.0005). Conclusions: Our study demonstrates that the combination of local infiltration and intraperitoneal instillation of ropivacaine is more effective for pain relief in children after laparoscopic surgery than the administration of ropivacaine only at the trocar sites.

Background: This study aimed to assess whether deferential reflux in pediatric and adolescent varicocele can be successfully treated laparoscopically. Materials and Methods: Since 2001 at our institution, 148 boys were evaluated for a left varicocele. Preoperatively, all the patients underwent ultrasound scan assessment of testicular volume and color-Doppler US (CDUS) to rule out reflux into the internal spermatic vein (ISV), deferential vein, or cremasteric vein. Boys with ISV reflux were treated by laparoscopic transperitoneal Palomo; boys with isolated deferential reflux or associated to ISV reflux were laparoscopically managed adding to the former procedure, coagulation or clipping of refluxing deferential veins. Results: Reflux in both the ISV and the deferential vein was observed in 21 (14.1%) out 148 boys with varicocele. Only one case (0.6%) of varicocele was caused by an isolated deferential reflux. No reflux in the cremasteric vein was observed. After a median follow up period of 2 years (range, 6 months–5 years), none of our patients with deferential reflux experienced varicocele recurrence either clinically or according to CDUS scanning. No testicular atrophy was observed. Conclusion: Our diagnostic approach is a rigorous standard for identifying all the venous systems concurring with the varicocele. Our proposed technique with laparoscopic interruption or coagulation of deferential veins when proved by CDUS to be refluxing may allow successful treatment for most varicoceles. This method allows reduction in recurrence of varicocele due to a missed deferential reflux. [ABSTRACT FROM AUTHOR]

Objectives: Gastroesophageal reflux (GER) and dismotility occur frequently after repair of esophageal atresia (EA). GER-associated complications can manifest either early or later; then precocious diagnosis and treatment are essential. The aim of the study was to evaluate characteristics of GER and esophageal clearance in children treated for EA with distal tracheoesophageal fistula, using pH-multichannel intraluminal impedance (pH-MII)., Patients and Methods: Twenty-two children (ages 3-40 months) treated for EA at birth, and 20 normal children of similar age with suspected GER disease were included in the study. Impedance parameters were analyzed according to age and symptoms., Results: Reflux events were mainly nonacidic. About bolus exposure index, mean acid clearing time (MACT), and mean bolus clearing time (MBCT), a significant difference was found between 2 groups: the median MACT and MBCT were longer, with values of 281 and 39 seconds, respectively, in the EA group and 110 and 15 seconds in the control group (P < 0.0005)., Conclusions: Our data show that in young patients the majority of refluxes are not acid. This implies that the incidence of GER may be underestimated if pH-metry is used. The pH-MII is an ideal test in children because it studies both GER with its characteristics and motility pattern. The quality of reflux does not seem to influence the onset of symptoms that are related to an impaired esophageal clearance. Hence, this technique could be useful to study patients treated for EA, avoiding the onset of complications.

Objective: Multichannel intraluminal impedance (MII) directly evaluates esophageal bolus transport. There is a good correlation between MII and manometry in healthy adults, but there are no reports concerning children.The aim of the present study was to determine normal values of esophageal motility using only impedance measurements in healthy children and in a pediatric population with gastroesophageal reflux (GER)., Patients and Methods: We described in the present study 60 children submitted to pH-MII for 24 hours for suspected GER. Patients were divided into 2 different groups on the basis of their pH-MII report. Group 1 patients showed acid GER, whereas group 2 patients had negative pH-MII analysis for GER despite symptoms. We described impedance reflux and motility parameters on 10 standardized swallows: number of reflux, mean acid clearing time, median bolus clearing time, bolus presence time, total bolus transit time, segmental transit time, and total propagation velocity., Results: In group 1, the median mean acid clearing time was 151 seconds, whereas the median mean bolus clearing time was 25 seconds. In group 2 patients, all of the reflux parameters were normal. In group 1 the median bolus presence time at each measuring site, the median total bolus transit time, and the median segmental transit time were significantly greater and total propagation velocity lower than values reported in group 2 (P < 0.001), if compared with those described for adult patients., Conclusions: The pH-MII is an ideal test in children because it studies GER with its characteristics and motility pattern. Our report summarizes for the first time impedance motility parameters in healthy children.

Hydrocele is defined as an abnormal collection of serous fluid in the potential space between the parietal and visceral layers of the tunica vaginalis. In the majority of affected adolescents, hydrocele is acquired and is idiopathic in origin. The pathogenesis of idiopathic hydrocele is thought to be an imbalance in the normal process of fluid production and reabsorption. The diagnosis is usually clinical. Taking a thorough history is essential to rule out any fluctuation in size, which is an indication of a patent processus vaginalis. Scrotal ultrasonography is mandatory in nonpalpable testicles to rule out a subtending testicular solid mass requiring inguinal exploration. Otherwise, open hydrocelectomy via a scrotal incision is the standard treatment of idiopathic hydroceles. The second most common cause of hydrocele in adolescents is varicocelectomy. The risk of hydrocele formation is higher with non-artery-sparing procedures or those performed without microsurgical aid, and in surgery requiring cord dissection. If hydrocele occurs after varicocelectomy, initial management should include observation with or without hydrocele aspiration. Large persistent hydroceles are best served by open hydrocelectomy.
