BACKGROUND Pyloric atresia (PA) is a rare pathology. Calder presented the first pyloric atresia case in 1749 and Touroff, Sussman, Meltz, and their colleagues presented the first successful operation in 1940. PA has 3 types of anatomic variations: (1) type A, pyloric membrane or web; (2) type B, the pyloric channel is a solid cord; and (3) type C, in which there is a gap between the stomach and duodenum. Associated anomalies also have been described. Epidermolysis bullosa (EB) and intestinal anomalies occur most often with this condition. METHODS Charts of 16 cases of congenital PA, aged 1 to 30 days and admitted to our department between 1986 and 2001, were studied retrospectively in regard to sex, prenatal diagnosis, presence of polyhydramnios, time of admission, pathology, type of operation, associated anomalies, and mortality rate. RESULTS In the study group, the male to female ratio was 5:3, the mean birth weight was 2,312 g and the mean age of admission was 6.5 days. The distribution of the anatomic variations was type A in 9 (56.3%) and type B in 7 (43.7%) of cases. Associated anomalies were present in 7 cases (43.8%). Familial occurrence was a prominent feature of our series. Seven of 16 cases occurred in 3 families. We performed 9 web excisions together with Heineke Mikulicz (H-M) pyloroplasty, 5 atresia excisions and gastro-duodenostomy, and 2 H-M pyloroplasties alone. Stamm gastrostomy was supplemented in 3 cases. The overall mortality rate (n = 9) was 56.3%. CONCLUSIONS Pyloric atresia can be managed successfully if it is diagnosed early. In this group of patients, congenital anomalies or septicemia are the main causes of mortality.

Abstract Between 1990 and 1999, 741 bronchoscopic procedures were performed in 698 children, 594 of whom were evaluated for foreign-body aspiration (FBA) (mean age 3.9 years, male:female 287/307). Based on the presenting symptoms, clinical outcome, and complications, two major groups were identified. Group 1 consisted of 438 patients with a definitive history of FBA. Most were admitted soon after the aspiration with sudden onset of symptoms such as coughing, choking, wheezing, and respiratory distress. Group 2 comprised 156 patients with chronic pulmonary infections and/or atelectasis without a definitive history of FBA. The most common radiographic finding was emphysema of one lung in group 1 (61.1%) and pneumonia in group 2 (70%). Among the patients in whom a FB was removed, the percentage of normal radiography was 17%. The FB was identified and removed in 83% of cases in group 1. The complication rate in this group was 9.8%, and all the complications were treated medically. Only 2 patients required intercostal drainage. In group 2, a FB was identified in 25% of bronchoscopic examinations and 17% of the patients developed complications. One of these patients underwent an urgent thoracotomy due to bilateral tension pneumothoraces and 2 required tracheostomies. Patients with a definitive history of FBA, even with a normal physical examination and radiographic findings, must undergo bronchoscopic investigation. Cases with late presentation and chronic pulmonary infection are at high risk. In this group care should be take in determining the indication and timing of bronchoscopy in order to prevent life-threatening complications.

Esophageal replacement using the colon : a 15-year review

Ergun Erdoğan; Haluk Emir; E. Eroğlu; N. Danişmend; Daver Yeker

Abstract Colonic interposition is a treatment option in childhood when esophageal replacement (ER) is necessary. We reviewed 18 children who underwent ER by colon between 1984 and 1999. There were 5 with esophageal atresia and 13 with corrosive esophagitis; 15 had long-term follow-up (mean 38 months). Three procedures were performed by the Waterston technique and 12 by the retrosternal technique. ER was completed in a single stage in all but 1 patient. Pyloroplasty or antireflux surgery were not done routinely during colonic interposition. As early complications, we observed 11 cervical leaks and 2 pulmonary problems. As late complications, there were 4 redundancies, 3 gastrocolic refluxes, 2 cervical anastomotic stenoses, and 1 each intestinal obstruction due to adhesions, cologastric stricture, cosmetic deformity of the thorax, and bulging of the neck. Six patients with complications required secondary surgery. There were 4 deaths, 2 of them unrelated to the surgery. Cervical leakage, which was the most commonly observed problem, healed well. We believe the colon is still one of the best substitutes for the esophagus and that there is no need to perform a routine pyloroplasty or antireflux procedure as an adjunct to the primary surgery.

Tracheostomy in childhood: 20 years experience from a pediatric surgery clinic

Zekeriya Ilçe; Sinan Celayir; Gonca Topuzlu Tekand; Nüvit Sari Murat; Ergun Erdoğan; Daver Yeker

Background : There is a limited indication for tracheostomy procedures in pediatric surgery. It is rarely applied to the pediatric patient because they can be kept intubated for a longer duration compared with adults. Problems and complications can occur after tracheostomy, even during the childhood period.

Neonatal Gastric Perforation: Review of 23 Years’ Experience

Cem Sultan Kara; Zekeriya Ilçe; Sinan Celayir; Nuvit Sarimurat; Ergun Erdoğan; Daver Yeker

PurposeTo review our experience of treating 13 neonates with gastric perforation (GP) over the past 23 years.MethodsThe records of all 13 patients were reviewed, noting gender, weight, gestational age, age at admission, associated anomalies, site of perforation, type of operation, and clinical outcome.ResultsThere were 11 boys and 2 girls, with a mean body weight of 2 375 g, including 4 (45%) preterm infants. The mean age at admission was 3.2 days. Three (23%) infants had associated anomalies. Perforation occurred in the lesser curvature and anterior wall in 3 (23%) infants, at the greater curvature and anterior wall in 2 (15.4%), in necrosis of anterior wall in 1 (7.7%), at the esophageal junction and posterior wall in 2 (15.4%), at the lesser curvature and posterior wall in 1 (7.7%), at the lesser curvature and esophageal junction in 1 (7.7%), and the site was not specified in 3 (23%). Twelve patients were treated with gastrorrhaphy and drainage, and 1 was treated with gastrorrhaphy alone. Three patients required additional gastrostomy. Mortality was 53.8% (n = 7). Early diagnosis and management before clinical deterioration of the metabolic status improved the prognosis.ConclusionThe pattern of presentation and surgical findings should be investigated comparatively in premature and full-term neonates, as the etiology of this condition is likely to differ in these two gestational groups.

Osman Faruk Şenyüz; A. C. Celayir; N. Kiliç; Sinan Celayir; Nuvit Sarimurat; Ergun Erdoğan; Daver Yeker

Abstract The records of 100 children with hydatid disease were reviewed retrospectively from 1978 to 1997; 43 were girls and 57 were boys. The mean age was 9.14 years; 61 patients had 124 hepatic cysts. Presenting symptoms were asymptomatic abdominal masses, found masses incidentally during ultrasonography (US), or acute abdomen. Plain X-ray films, US, or computerized tomography (CT) are sufficient for diagnostic evaluation in endemic areas. In the differential diagnosis, laboratory investigations such as the Casoni and Weinberg tests, indirect hemagglutination, eosinophilia, and ELISA were also used. These tests may give negative results, however, in some patients with hydatid disease. The mean follow-up time was 10.5 years (range 1–18 years), the mean duration of hospitalization 7 days. The complication rate was 3.6%. Mortality was 3.27% and occurred after the administration of formaldehyde and hypertonic scolicidal agents. Hydatid disease of the liver can be treated medically in selected patients; conservative surgical approaches that save as much parenchyma as possible, such as partial cystectomy and capitonnage, are indicated in the other cases.

PurposeWe review our experience of treating intestinal rotation anomalies in infants and children in the 22-year period between 1978 and 2000.MethodsThe type of operation performed, postoperative complications, and mortality were compared in three age groups. Group 1 consisted of neonates ≪1 month old, Group 2 consisted of infants aged ≪1 year old, and Group 3 consisted of children aged ≫1 year old.ResultsThere were 101 infants and children, with a female : male ratio of 2 : 1. Of the 101 patients, 72 (71%) were neonates, with a mean age of 11.8 days (range 1–28 days); 20 (19.8%) were under the age of 1 year, with a mean age of 6.7 months (range 1–12 months); and 9 (8.9%) were ≫1 year of age, with a mean age of 6 years (range 1–9 years). Eighty-five (84%) patients underwent emergency procedures. Ladd’s operation was performed in all patients, with various additional procedures. The most frequent postoperative complications were adhesive intestinal obstruction, stoma necrosis, evisceration, and short bowel syndrome. The mortality rate was 36% in Group 1, 20% in Group 2, and 0% in Group 3.ConclusionsIn this series surgery was usually performed as an emergency procedure, with higher morbidity and mortality in newborns than in older infants and children.

E. Eroğlu; Ergun Erdoğan; G. Gundogdu; Sergülen Dervişoğlu; Daver Yeker

Abstract Appendiceal anomalies are extremely rare malformations that are usually found in adult population as an incidental finding during laparotomy due to another reason. When appendiceal duplications are detected in childhood, almost all the patients have serious associated intestinal, genito-urinary or vertebral malformations. Presented herein are a case of a huge (15×13 cm mass) appendiceal duplication in a child causing acute abdomen without an accompanying pathology, its differentiation from appendiceal and caecal diverticulum, and classification of appendiceal duplications with the review of literature.

Nuvit Sarimurat; Sinan Celayir; Mehmet Eliçevik; Sergülen Dervişoğlu; Daver Yeker

Congenital short bowel with functional intestinal obstruction and absence of appendix vermiformis is a very rare condition with poor prognosis. Seventeen cases of congenital short bowel have been reported previously in the literature. The etiology is unknown. In this report, a case of congenital short bowel, combined with functional intestinal obstruction, mal-rotation, and absence of the appendix vermiformis, is presented and the pathogenesis discussed.
