Anomalous congenital bands causing intestinal obstruction in children.

The records of eight patients treated for intestinal obstruction resulting from bands that have no identifiable embryologic or acquired basis were reviewed retrospectively. All patients presented with symptoms and signs indicative of intestinal obstruction. Patients older than 2 years of age additionally had a history of chronic abdominal pain. One thick anomalous congenital band with blood vessels in it was found to be the cause of obstruction in each patient. Bands were located between ascending colon and terminal ileum in four patients (50%), ligament of Treitz and terminal ileum in two patients (25%), right lobe of liver and terminal ileum in one patient (12.5%), and right lobe of liver and ascending colon in one patient (12.5%). The obstructive mechanisms were compression of bowel by band in five patients (62.5%) and entrappment of an intestinal loop between the band and mesenterium in three patients (37.5%). These bands are suggested to be the anomalies of mesenterium that may cause intestinal obstruction and chronic abdominal pain in children.

The necessity of prophylactic antibiotics in uncomplicated appendicitis during childhood.

A prospective, randomized, clinical study was done to evaluate the place of prophylactic antibiotics in uncomplicated childhood appendicitis. One hundred patients with uncomplicated appendicitis were randomly assigned to one of four groups, each consisting of 25 cases. Group 1 patients did not receive prophylactic antibiotic. Group 2, group 3, and group 4 patients received ornidazole, penicillin plus tobramycin, and piperacillin, respectively. The use of prophylactic antibiotics did not yield better results than the use of placebos. The rarity of infectious complications after uncomplicated appendicectomy may be unique for children. Although the need for antibiotic prophylaxis is well documented in adults, the rarity of infectious complications makes it highly questionable in the treatment of uncomplicated appendicitis in children.

Conservative treatment of caustic esophageal strictures in children.

The most common cause of esophageal stricture in children is the accidental ingestion of strong corrosive agents. During a 13-year period between 1976 and 1989, 202 patients were diagnosed as having caustic esophageal strictures at the Hacettepe University Children's Hospital Department of Pediatric Surgery. A retrospective clinical study was performed to find out the place and predictors of a successful outcome for conservative treatment in children who have caustic esophageal strictures. Two hundred two children, of whom 145 were male (71.7%) and 57 female (28.3%) with 168 (83.2%) being younger than 6 years of age, were evaluated retrospectively. Whereas only 49.3% of patients could be treated within a 12-month period, 50.7% needed more than 1 year, 32.9% needed more than 2 years, 26.7% needed more than 3 years, and 15.4% needed more than 4 years of periodic dilations in order to become swallowers through native esophaguses. The success of conservative treatment has been higher in patients younger than 8 years of age, and in strictures due to caustics other than lye involving upper third portion and less than five cm of an esophageal segment. Most caustic esophageal strictures could have been treated by conservative measures in children.

Colonic replacement for the treatment of caustic esophageal strictures in children.

Caustic esophageal stricture is one of the most common indications for esophageal replacement in children. During a 13-year period between 1976 and 1989, colonic replacement was performed in 50 patients for the treatment of caustic esophageal strictures at the Department of Pediatric Surgery of Hacettepe University Children's Hospital. A retrospective clinical study was undertaken to discuss the indications and results of colonic replacement. The 50 children, 34 of whom were male (68%) and 16 of whom were female (32%) with 27 patients (54%) under 6 years of age, were evaluated retrospectively. Indications for operation included 21 (42%) who could not swallow saliva and had total or nearly total obliteration of lumen involving more than 3 cm of an esophageal segment at admittance, and 16 (32%) who had difficulty in swallowing within a 1-month period following the last dilation after completion of a 1-year dilation program. A further 13 (26%) had bleeding and difficulties during dilations, after experiencing an esophageal perforation. The right colon was used in 48 and the left in the remaining 2 patients. Patients were followed for at least 1 year following replacement. Growth was excellent in all but one patient who had redundant colon and showed growth retardation. There was one postoperative late death because of massive bleeding from ulceration of the transplanted colon. The other 49 patients were available for accurate follow-up. The results were good, 46 (92%) were able to eat everything, while occasional dysphagia in 3 (6%) required dilation after operation. Colon conduit provides an excellent substitute for esophagus in pediatric patients.(ABSTRACT TRUNCATED AT 250 WORDS)

Adhesive small bowel obstruction in children: the place and predictors of success for conservative treatment.

The records of 230 adhesive small bowel obstruction (ASBO) episodes in 181 patients have been reviewed to observe the place of conservative treatment and to establish criteria to predict the success of conservative trial. Immediate operation has been reserved for 81 episodes that have presented with fever and leucocytosis and/or localized abdominal tenderness, or complete obstruction. The remaining 149 episodes have initially undergone conservative trial. Although 110 episodes (73.8%) have been cured with conservative trial, 39 (26.2%) subsequently necessitated surgical intervention. No adverse occurrences have been observed during or after delayed operations. There was no strangulated bowel nor mortality both in delayed operation and conservatively treated groups. Recurrence has occurred with rate of 18.75% and 36.47% after surgery and conservative treatment, respectively, being significantly different (P less than .01), but the treatment method of the previous episode has been without influence on the method used in the recurrent obstruction (P less than .05). Among the assumed predictive criteria, age at recent laparotomy (P less than .02), time elapsed between recent laparotomy and obstructive episode (P less than .01), the primary condition necessitating laparotomy (P less than .01), the incision of previous laparotomy (P less than .05), and duration of conservative trial (P less than .01) correlated significantly with the success of conservative trial. The number of previous laparotomies and obstructive episodes (P less than .05) have not showed correlation. By the conservative approach used in selected patients with ASBO, 40% overall have been spared operation, without any adverse occurrences. Using the proposed criteria, the success rate of conservative treatment can be predicted.

Subsequent testicular histology: fertility and fecundity of rats subjected to unilateral incarcerated inguinal hernia during the prepubertal period.

An experimental study was designed to evaluate subsequent ipsilateral and contralateral testicular histologies, fertility, and fecundity of rats subjected to unilateral incarcerated inguinal hernia during the prepubertal period. Three study groups each containing 12 rats (28-day-old) were established. In group 1 the rats were only anesthetized. In group 2 the rats had undergone a sham operation. Left-sided incarcerated inguinal hernias were created in rats constituting group 3. After the rats had reached 4 months of age, each male rat was housed with two known fertile female rats for 3 weeks. Male rats were then castrated and the testes were evaluated histologically. Female rats were followed for 30 additional days, and the number of females impregnanted and the number of rats given birth to by each female rat were recorded. Left-sided incarcerated inguinal hernia has caused a lessened testicular/body weight ratio in the left testes, and histological deteriorations in both left and right testes that were expressed through diminished mean seminiferous tubular diameter and mean testicular biopsy scores. The fertility rate was not affected, but the number of rats produced by each male rat was lesser after having the incarcerated inguinal hernia. Unilateral incarcerated inguinal hernia during prepubertal period resulted in deteriorated ipsilateral and contralateral testicular histology and diminished the exocrine function of testes in rats.

Primary realignment of posterior urethral ruptures in children.

Primary realignment was used in the treatment of 12 children with complete rupture of the posterior urethra; 10 developed strictures but 7 of these responded to dilation. Problems of continence were encountered only in patients who developed strictures. Since primary realignment results in dilatable strictures in most patients, it is suggested that this should be the treatment of choice in children.

Contralateral testicular blood flow during unilateral testicular torsion.

Changes in contralateral testicular blood flow during unilateral testicular torsion were evaluated using an electromagnetic flowmeter in 13 adult male New Zealand White rabbits. There was an immediate and then a progressive decrease during torsion and a gradual increase following detorsion. A decrease in testicular blood flow over a critical period of time may be associated with contralateral testicular damage following unilateral testicular torsion.

The fate of testes following unilateral incarcerated inguinal hernia in adult rats.

The histological effects of unilateral incarcerated inguinal hernia on the ipsilateral and contralateral testes were examined in adult rats. Three groups were established. In the first group the left testis and caecum were exposed and replaced. In group 2 a left-sided incarcerated inguinal hernia was created with bilateral orchiectomy 24 h later. In group 3 a left-sided incarcerated inguinal hernia was created with reduction after 24 h. The testes of animals in groups 1 and 3 were removed after 15 days. The mean seminiferous tubular diameter (MSTD) and mean testicular biopsy score (MTBS) were determined for ipsilateral and contralateral testes in each of the 3 groups. A decreased MSTD and depressed MTBS, were pronounced in the ipsilateral testes, were found in the testes of group 3 animals. While unilateral incarcerated inguinal hernias caused more pronounced histological changes in the ipsilateral testes, they also affected the contralateral testes, but a time interval was required for the changes to become manifest.

Sarco(endo)plasmic reticulum and plasmalemmal Ca(2+)-ATPase activities in cremaster muscles and sacs differ according to the associated inguinal pathology.

Sarco(endo)plasmic reticulum Ca(2+)-ATPase (SERCA) and plasmalemmal Ca(2+)-ATPase (PMCA) activities in cremaster muscles and sacs, which have been subjected to different autonomic tonuses, were determined and compared. Samples of cremaster muscles and sacs associated with male or female inguinal hernia, hydrocele or undescended testis were obtained from children during operations and activities of SERCA and PMCA were determined. While highest SERCA and PMCA activities were encountered among cremaster muscles and sacs associated with undescended testis, least activities were encountered among structures associated with hydrocele. The alterations in SERCA and PMCA activities in cremaster muscles associated with undescended testis appear to reflect the attempts at maintaining the levels of cytosolic calcium. Despite similar total calcium contents, lower SERCA and PMCA activities were found in sacs associated with hydrocele compared to those associated with undescended testis suggest a difference among the levels of cytosolic calcium.

Redo operations of Hirschsprung's disease.

The purpose of this study was to specify the indications, applicability and final outcome of the redo definitive operations of Hirschsprung's disease. Between 1976-1993, 213 patients had undergone definitive operations of Hirschsprung's disease. In this series, 5 who required a redo pull-through operation were investigated. The redo pull-through operations were performed in 5 patients because of severe anastomotic stricture or total closure of the anastomotic site, recto-urethral fistula, anastomotic stricture, and enterocolitis due to anastomotic disruption. The initial definitive procedures were in 4 patients the Swenson operation and in one patient the Boley operation. As redo pull-through operations, the following were performed with success: in 3 patients, the Duhamel operation; and in 2 patients, the Swenson operation. The final outcome of the redo pull-through alterations were satisfactory and it can be suggested that one should not hesitate to perform a redo pull-through operation in selected Hirschsprung patients.

Respiratory distress due to esophageal perforation caused by ball point ingestion.

A 15-month-old girl who developed respiratory distress which persisted for three days prior to admission demonstrated pleural effusion on the chest x-ray which was determined to be due to esophageal perforation caused by the ingestion of a ball point. A gastrotomy was performed to extract the ball point. A gastrostomy was performed and a chest tube was inserted. The esophagus was normal radiologically within one month. Foreign body ingestion may cause esophageal perforation in childhood. If it goes unnoticed and a diagnosis is delayed, there is danger of the more hazardous development of mediastinitis. It is important that a child with respiratory distress also be evaluated for esophageal foreign body ingestion.
