DIAGNOSTIC ACCURACY OF BARIUM ENEMA FINDINGS IN HIRSCHSPRUNG'S DISEASE.

Arq Bras Cir Dig 2016 Jul-Sep;29(3):155-158

Nursing Care Research Center in Chronic Diseases and Department of Pediatric Gastroenterology, Ahvaz Jundishapur University of Medical Sciences, Ahvaz, Iran.

Background: Hirschsprung's disease is the most common cause of pediatric intestinal obstruction. Contrast enema is used for evaluation of the patients with its diagnosis.

Aim: To evaluate sensitivity, specificity, positive predictive value, and negative predictive value of radiologic findings for diagnosis of Hirschsprung in patients underwent barium enema.

Methods: This cross sectional study was carried out in Imam Khomeini Hospital for one year starting from 2012, April. Sixty patients were enrolled. Inclusion criteria were: neonates with failure to pass meconium, abdominal distention, and refractory constipation who failed to respond with medical treatment. Transitional zone, delay in barium evacuation after 24 h, rectosigmoid index (maximum with of the rectum divided by maximum with of the sigmoid; abnormal if <1), and irregularity of mucosa (jejunization) were evaluated in barium enema. Biopsy was obtained at three locations apart above dentate line. PPV, NPV, specificity , and sensitivity was calculated for each finding.

Results: Mean age of the cases with Hirschsprung's disease and without was 17.90±18.29 months and 17.8±18.34 months respectively (p=0.983). It was confirmed in 30 (M=20, F=10) of cases. Failure to pass meconium was found in 21(70%) cases. Sensitivity, specificity, PPV, and NPV were 90%, 80%, 81.8% and 88.8% respectively for transitional zone in barium enema. Sensitivity, specificity, PPV, and NPV were 76.7%, 83.3%, 78.1% and 82.1% respectively for rectosigmoid index .Sensitivity, specificity, PPV, and NPV were 46.7%, 100%, 100% and 65.2% respectively for irregular contraction detected in barium enema. Sensitivity, specificity, PPV, and NPV were 23.3%, 100%, 100% and 56.6% respectively for mucosal irregularity in barium enema.

Conclusion: The most sensitive finding was transitional zone. The most specific findings were irregular contraction, mucosal irregularity, and followed by cobblestone appearance.

END-TO-END VERSUS END-TO-SIDE ANASTOMOSIS IN THE TREATMENT OF ESOPHAGEAL ATRESIA OR TRACHEO-ESOPHAGEAL FISTULA.

Arq Bras Cir Dig 2016 Mar;29(1):48-9

Department. of Pediatric Gastroenterology, Abuzar Children's Hospital, Ahvaz Jundishapur University of Medical Sciences, Ahvaz, Iran.

Background: Dehiscence of esophageal anastomosis is frequent and there are still controversies which type of anastomosis is preferred to diminish its incidence .

Aim: To compare end-to-end anastomosis versus end-to-side anastomosis in terms of anastomotic leakage, esophageal stricture and gastroesophageal reflux symptom.

Methods: This study was carried out for two year starting from 2012. End-to-side and end-to-side anastomosis were compared in terms of anastomotic leakage, esophageal stricture, gastroesophageal reflux symptom, length of surgery and pack cell infusion.

Results: Respectively to end-to-end and end-to-side anastomosis, duration of surgery was 127.63±13.393 minutes and 130.29±10.727 minutes (p=0.353); esophageal stricture was noted in two (5.9%) and eight (21.1%) cases (p=0.09); gastroesophageal reflux disease was detected in six (15.8%) and three (8.8%) cases (p=0.485); anastomotic leakage was found in five (13.2%) and one (2.9%) cases (p=0.203); duration of neonatal intensive care unit admission was significantly shorter in end-to-end (11.05±2.438 day) compared to end-to-side anastomosis (13.88±2.306 day) (p<0.0001).

Conclusion: There were no significant differences between end-to-end and end-to-side anastomosis except for length of neonatal intensive care unit admission which was significantly shorter in end-to-end anastomosis group.

Omphalocele, gastroschisis: epidemiology, survival, and mortality in Imam Khomeini hospital, Ahvaz-Iran.

Pol Przegl Chir 2012 Feb;84(2):82-5

Department of Surgery, Imam Khoemini Hospital, Ahvaz Jundishapur University of Medical Sciences, Ahvaz, Iran.

Unlabelled: Gastroschisis and omphalocele are the most common malformation of the anterior abdominal wall.The aim of the study was to determine the abdominal wall defect frequencies, survival, and mortalities in Ahvaz, Khuzestan province of Iran.Materiał and methods. All cases born with omphalocele or gastroschisis whom born in Imam Khomeini hospital, were included in this study. Duration of study was 3 years from April 2005. All patients treated at Imam Khomeini hospital in Ahwaz, Iran.Results. Among 15321 consecutive births, 42 patients had abdominal wall deformity. Overall incidence was 27.41 per 10,000 live births. Of all cases, 18 (42.9%) of cases were male and 24 (57.1%) were female. Of all cases, 21.7% of patients with omphalocele and 10% patients with gastroschisis had other anomalies. Of all cases, 71.8% of patients with omphalocele and 60% with gastroschisis underwent surgery. The type of anomaly (omphalocele and gastroschisis) had correlation with post operation prognosis significantly (p<0.001). Of 66.7% of patients under went surgery, 46.4% with mesh and 53.6% without mesh performed. 80% of patients with omphalocele and 20% with gastroschisis were lived.

Conclusions: In our study, mortality was significantly higher in cases with gastroschisis than cases with omphalocele.
