ABSTRACT
Purpose@#Two-millimeter needlescopic instruments induce minimal damage to the abdominal wall and have excellent cosmetic benefits. We aimed to evaluate the feasibility of a laparoscopic intracorporeal suture using 2-mm instruments for pediatric inguinal hernia. @*Methods@#We retrospectively reviewed 131 patients who underwent laparoscopic repair between March 2011 and February 2017. Three trocars were used: a 5-mm umbilical trocar for a needle holder and two 2-mm trocars for a camera and a grasper. The internal ring was closed with an intracorporeal purse-string suture. A telephone interview was conducted to confirm recurrence. @*Results@#In the 131 patients, 169 procedures were successfully performed. The ages ranged from 2 months to 14 years (mean, 52.5 months), and the mean body weight was 18.0 kg (range, 6.7~49 kg). The mean operating time was 42 minutes for the unilateral cases and 46 minutes for the bilateral inguinal hernia repairs. All the cases were completed laparoscopically without intraoperative complications. Herniotomy was not performed in all the patients except nine. A contralateral patent processus vaginalis was present in 27.3% (35/128) of the patients. During the mean follow-up period of 54.6 months, 3 recurrences (2.3%) were observed. Two recurrences were treated using laparoscopy and one using open herniorrhaphy. Hydrocele occurred in one male patient. No wound complications or umbilical hernias developed. No testicular atrophy was observed. @*Conclusion@#This study showed that laparoscopic intracorporeal internal ring suture using 2-mm instruments for pediatric inguinal hernia was technically feasible and safe, with excellent cosmetic results.
ABSTRACT
This morphometric study of the trachea was performed to provide the basic data necessary for shielding crico-thyroid membrane incision, tracheal intubation and tracheotomy in korean bodies 48 (33 male, 15 female). Tracheal measurement included the number, the length, the anteroposterior and transverse diameters of trachea, and the height of tracheal cartilages, and the inter-rings distances of cartilages. The length of trachea was 104.0+/-1.4 mm in male and 102.3+/-1.9 mm in female, but there was no significance between males and females. All of the anteroposterior and transverse diameters, and the height were longer in males, compared with females, in the first, fifth, tenth and fifteenth tracheal cartilages. The anteroposterior and transverse diameters of the first and fifteenth tracheal rings, and the height of the first tracheal ring differed significantly male's from female's. The distances between posterior end of rings of the first, tenth and fifteenth tracheal cartilages were broader in males. The inter-rings distances of tracheal cartilage were also wider in the male, and showed significant differences in the 1st~2nd and 10~11th. These results suggest that this might be useful as a clinical basic data for the emergency physician, anesthetist, and associated medical doct
