Initial evaluation of children sustaining blunt abdominal trauma: ultrasonography vs. diagnostic peritoneal lavage.

A prospective clinical study was performed to compare ultrasonography (US) with a modality having 96-99% accuracy like diagnostic peritoneal lavage (DPL) to find the accuracy of US in the initial evaluation of children sustaining blunt abdominal trauma (BAT). Sixty-eight children with BAT were initially evaluated by US, then DPL. All patients with pathologic US findings underwent computerized tomographic examination before DPL to confirm the pathologies. Through US examination free intraperitoneal fluid (FIF) was present in eleven, absent in 57 patients. DPL was positive in ten, negative in 58 patients. Sensitivity, specificity, negative predictive value, positive predictive value and efficiency of US were 100, 98.3, 100, 91 and 98.5 respectively. US detected intraperitoneal solid organ injuries in eleven patients, but DPL was positive in only ten of these patients. While US detected renal injuries in six patients and intrapleural fluid in two patients, DPL was positive in only two of these patients as a result of concomitant intraperitoneal solid organ injuries with FIF. The present study has shown that US can detect FIF with a high rate of accuracy comparable to DPL in children. In addition, US has advantages over DPL in the detection of intraperitoneal organ injuries with or without concomitant FIF, retroperitoneal injuries and intrathoracic injuries. Thus US is thought to be superior to DPL and recommended as a routine first choice screening tool in the initial evaluation of children sustaining BAT.

Outpatient catheterless Mathieu repair: how to cover ventral penile skin defect.

A modification of the Mathieu repair eliminating stenting has been described by Rabinowitz which makes the method more convenient for outpatient performance. We report on our experience with this modification with special emphasis on coverage of ventral penile skin defect. To cover the raw area formed on the ventral aspect of penis with the creation of meatal based flap Rabinowitz used Byar's flap. Two different flaps prepared from prepuce were used in this series. In some patients an island flap was used. In others the prepuce was incised transversally on its dorsal aspect and transferred to the ventral surface as a bipedicle visor flap, as described by Ombrédanne and popularized by Nesbit. Twenty-two patients ranging in age from one to twelve years (mean +/- 1SD = 6 +/- 3.28) were operated on using the technique. The meatus was glandular in two, coronal in twelve and distal penile in eight patients. Preputial flap was not used in one patient because the defect was small. Island flap was used in three and Ombrédanne-Nesbit's flap in 18 patients. Complete disruption of the repair occurred in one of the patients in whom an island flap was used. Among 18 patients in whom Ombrédanne-Nesbit's flap was used, one partial necrosis of the preputial flap was encountered which required revision and two urethrocutaneus fistulae occurred which healed spontaneously. The use of the present technique yields a good cosmetic result, a high success rate with minimal complications, and eliminates catheterization; hence, hospitalization is recommended.

Experimental study investigating the feasibility of a new method for laparoscopic indirect inguinal hernia repair.

With the progress in laparoscopic techniques in recent years, there is an increased interest in laparoscopic hernia repair. The laparoscopic indirect inguinal hernia repair with simple closure of the internal ring seems feasible in childhood inguinal hernia repair; however, this technique carries the risk of postoperative patent processus vaginalis. In this-study we investigated the possibility of avoidance of this complication by chemical obliteration of processus vaginalis with 6% iodine solution in rats. The study population was comprised of three groups: simple suture of the internal ring, iodine application plus simple suture of the internal ring, and iodine application alone. While processus vaginalis was anatomically closed in 75% of the rats in the iodine plus simple suture of the internal ring group, it was closed in 10% of the iodine application alone group and was not closed in the simple suture of the internal ring alone group. No histopathologic injuries to the testis or cord were detected attributable to iodine. Our study showed that simple suture of the internal ring is not sufficient for hernia repair. Laparoscopic chemical agent application in addition to simple suture of the internal ring may be beneficial for successful laparoscopic indirect inguinal hernia repair in children.
