Neonatal appendicitis (NA) is a very rare surgical condition. The aim of this study is to once again draw attention to this subject by collecting our cases with NA and cases of NA reported separately in English-language literature over the period from 1901 to 2000. We performed a retrospective chart review of patients admitted to our hospital, with the clinical diagnosis of NA from 1990 to 2000. A survey of the English-language literature together with our own 7 cases revealed a total of 141 cases of NA during the period of 1901–2000. 128 cases had sufficient information for analysis. The patients are grouped and discussed according to these 3 time– periods: 1901–1975, 1976–1984 and 1985–2000. The incidence, etiology, and presenting signs and symptoms of appendicitis in newborns are discussed. Despite the similar perforation rates in the 3 time– periods (73%, 70%, 82%), mortality rate in NA has decreased from 78% in the 1901–1975 period, to 33% in the 1976–1984 period, and to 28% in the 1985–2000 period. A newborn baby presenting with continuous vomiting, refusal to feed, and , showing signs of pain through irritability, restlessness, sleep disturbance, and a distended abdomen; one should strongly suspect an abdominal disorder, perhaps appendicitis.

BACKGROUND/PURPOSE This study describes the pediatric inguinal hernia and hydrocele experience of a tertiary care training hospital. METHODS A total of 3776 patients who had been operated between January 2005 and June 2009 for inguinal hernia, cord hydrocele, and hydrocele were included. The surgeries and patient follow-up were performed by 6 pediatric surgery specialists and 8 pediatric surgery residents. RESULTS The patient age varied from 6 days to 17 years. There were 2959 (78.4%) males and 817 (21.6%) females (ratio: 3.6:1). The hernia was on the right in 2306 (61.1%) patients, on the left in 1111 (29.4%) patients, and bilateral in 359 (9.5%) patients. Age at presentation was younger in males (p<.001). Contralateral hernia repair was required later on during follow-up in 2% of the patients. Postoperative complications developed in 1.2% of the patients. Reoperation was needed because of wound infection in 0.6%, recurrence in 0.4%, hematoma in 0.1%, testicular atrophy in 1 patient, and acquired undescended testis in 1 patient. CONCLUSIONS The age of first hernia symptoms was younger in males compared to females and in premature babies compared to term babies (p<.05). The recurrent hernia rate was higher in infancy. The complication rate was higher in hernia surgery in the newborn period and in cases of incarcerated hernia compared to the overall rate (p<.05). There was no indication for contralateral routine exploration.

Objective: Acute scrotal pain is a common urological emergency. Urgent exploration is the standard means of management, since no investigation can confidently exclude torsion of testis from the differential diagnosis.Methods: A review of all boys presenting with acute scrotal pain who underwent emergency scrotal exploration between January 1983 and March 2003 was performed.Results: 195 boys were included in this study. They were divided into 3 groups: group 1–73 with epididymo-orchitis, group 2–63 with torsion of testicular appendages and group 3–57 with spermatic cord torsion. The patients in group 2 were older than group 1, also patients in group 1 were older than group 3. During neonatal period the most common pathology was spermatic cord torsion, whereas in prepubertal period torsion of appendages was more common. In all boys, mean duration of pain at presentation was 2.11 days. Epididymo-orchitis was diagnosed in 37% of patients, with torsion of the appendages being the next most common entity. Testicular torsion was diagnosed in 29% of patients. In the group with testicular torsion salvage rate of testis was 37% because of late admission. The perioperative morbidity and mortality was not seen in any of the groups.Conclusion: We believe that any boy with acute scrotal pain and any suspicion of testicular torsion in physical examination must be applied routine surgical exploration.

Swallowing foreign bodies is a common problem in children. Although most objects pass through the gastrointestinal tract with no untoward effect; long, sharp-pointed, or slender objects can perforate the gut. Migration of an object to the liver is extremely rare and very few cases have been reported in the literature. The aim of this study is to draw attention to this subject once again by contributing a case report of a child with a hepatic sewing needle. A survey of the literature over the period from 1971 to 2006 revealed a total of five cases of childhood hepatic sewing needle together with our case. The practical lesson illustrated by this report is that the surgeon must carefully evaluate the liver when foreign body was not found in gastrointestinal system and also perforation site was found anywhere.

PurposeTo evaluate childhood bicycle handlebar injuries.MethodsWe evaluated retrospectively 14 patients who presented with bicycle handlebar injuries within a 3-year period. Bicycle injuries not caused by the handlebar were excluded.ResultsThe mean age of the patients was 8.8 ± 2 years (range, 5–12 years) and 79% were boys. The injuries comprised gastrointestinal perforation in 21%, traumatic abdominal hernia in 21%, and spleen laceration in 14%. The three children with intestinal perforation and the one with a penetrating abdominal injury underwent surgery, whereas the others were treated medically. An isolated traumatic abdominal hernia resolved spontaneously. There was no mortality.ConclusionsAlthough bicycle handlebar injuries occur at relatively low speeds, the transfer of energy from the end of the handlebar, with a small cross-sectional area, to a small field leads to intra-abdominal injuries that are more severe than predicted. Thus, bicycle handlebar injuries should be considered as a serious intraabdominal injury until proven otherwise.

Superficial epithelial ovarian tumors are unusual in adolescent girls (when compared with adult women) and extremely rare before menarche. Mucinous cystadenoma (MCA) in children that is a rare form of epithelial tumor is a benign cystic ovarian neoplasm. To our knowledge, there are only eight cases of mucinous cystadenoma, three of borderline mucinous cystadenoma, and three of mucinous cystadenocarcinoma reported in the English-language literature. We present a 14-year-old premenarchal girl with a giant ovarian mucinous cystadenoma. This review is supported by the finding that epithelial ovarian neoplasms are extremely rare prior to puberty and that only 14 mucinous tumors have been reported prior to menarche.

BACKGROUND/PURPOSE Pilonidal disease is a common and frustrating problem among adolescents due to its high recurrence rate. The rhomboid excision and Limberg flap techniques promise successful results, but the lower part of the incision left on the intergluteal sulcus is prone to recurrences. Consequently, we have developed a new modification to this technique and have designed a descriptive prospective study to evaluate its efficiency. METHODS We conducted this prospective study between March 2011 and March 2012. All of the patients who were operated on for sacrococcygeal pilonidal disease were included in this study. The surgical procedure primarily consisted of symmetrically rotated (clockwise) rhomboid excision and lateralization of the Limberg flap in order to keep the inferior corner of the suture line apart from the intergluteal sulcus. RESULTS A total of 15 adolescents (8 boys and 7 girls) were included in the study group. Of the patients, 47% were normal, 13% were overweight, and 40% were obese. Five patients were operated on under general anesthesia, and 10 were operated on under spinal anesthesia. The length of the flap margins ranged from 2.5 to 7 cm (median=4 cm). The median duration of hospitalization was 5 days, and the median duration of suction drainage was 4 days. The median postoperative follow-up period was 4 months (ranging from 1 to 12 months), and we did not encounter any wound infection or recurrent disease during this period. Only one patient had wound hematoma as a result of drain breakdown and was treated with wound care without any additional complications. CONCLUSION Although the number of patients in this study was small and the follow-up period was short, we obtained satisfactory results without any recurrence by performing a symmetrically rotated rhomboid excision and lateralized Limberg flap procedure.

INTRODUCTION The aim of this study was to determine whether the addition of gum chewing to standardized postoperative care is associated with a significantly earlier return of bowel function compared to simple postoperative management in children with intestinal anastomosis. MATERIALS AND METHODS We performed a prospective, randomized, controlled trial. All patients who underwent laparotomy with either colon or small bowel resection between June 2006 and March 2008 were randomized to one of two groups. Group one consisted of patients receiving standardized postoperative care plus gum chewing (gum-chewing group) (n=15); Group two consisted of patients receiving only standardized postoperative care (control group) (n=15). The patients in the gum-chewing group chewed one stick of sugarless gum three times per day, for an hour, each day. RESULTS The groups were statistically similar. The time to first flatus was 35.73+/-14.67 h in the gum-chewing group and 42.00+/-20.77 h in the control group (p=0.347). The time to first bowel movement was 56.27+/-22.14 h in the gum-chewing group and 63.00+/-26.34 in the control group (p=0.444). The length of hospital stay was 5.80+/-0.68 days for the gum-chewing group and 6.67+/-0.98 days for the control group (p=0.005). The hospital charges were 2451+/-806 YTL for the gum-chewing group and 2102+/-678 YTL for the control group (p=0.206). CONCLUSIONS The addition of gum chewing to the standardized postoperative care of children with intestinal anastomosis was not associated with a significantly earlier return of bowel function compared to simple postoperative management, but it was associated with an earlier discharge from hospital, although this earlier discharge had only minor clinical significance and no difference was found in hospital charges.

PURPOSE We investigated the efficacy of ultrasound in determining megarectum and fecal load and the response to treatment in constipation and tried to specify objective criteria in this study. METHODS A total of 66 cases were queried and divided into 2 groups as constipated (n = 35; mean age, 6.8 ± 2.9 years) and control (n = 31; mean age, 8.4 ± 3.8 years) according to Rome III criteria. After the clinical evaluation, pelvic ultrasonography (US) was performed by 2 separate radiologists. The bladder capacity and the transverse rectal diameter were measured with a full bladder. Then the rectal diameter and rectal anterior wall thickness were measured, and the presence of fecal load in the rectum and sigmoid colon was recorded with an empty bladder. The examination and ultrasound were repeated after treatment for a month in these patients. RESULTS Comparison of the US measurements of the 2 radiologists performing the US tests did not show any interobserver difference (r = 0.981; P < .001). We therefore believe our results are objective and reproducible. We found a positive correlation between the rectal diameters and the age, height, weight, and bladder capacity. The posturination mean rectal diameter was thicker in the constipated group (3.02 ± 1.04 cm) than in the control group (1.98 ± 0.64 cm) (P < .001). The cutoff point of rectal diameter for a diagnosis of constipation was determined as 2.44 cm (71% sensitive; 76% specific; area under curve, 0.825; P < .001). The rectal anterior wall thickness and fecal load were higher in the constipated patients (P < .001). There was a significant decrease in the constipation score and fecal load after treatment for a month (P < .001), but the rectal diameter had not reached normal limits yet despite the decrease (2.71 ± 0.77 cm) (P > .05). CONCLUSION The use of US helps in making a correct diagnosis and in the follow-up with objective criteria and also convinces the patient and the family that the treatment needs to be continued.
