Clinical pattern of colonic atresia, management, and outcome in an indian tertiary Care Center

Introduction: Colonic atresia (CA) is an important cause of congenital intestinal obstruction and frequently associated with other comorbidities. Colon is the least common site of gastrointestinal atresias, and no large series can be documented because of the rarity of the anomaly. Historically, majority of the patients were being managed by staged approach; initial ostomy formation followed by delayed repair. Objective: The objective of this study was to analyze the demographic pattern, management approach in our set up and to compare the outcome with similar available studies. Materials and Methods: This is a retrospective study on infants with CAs managed between October 2016 and March 2019. Results: CAs constituted 10% of all gastrointestinal atresias managed in our study and females were more commonly affected. Atresias were located most commonly in sigmoid colon (7 cases), and Type III was the most common anomaly. Five patients had associated anomalies such as gastroschisis, malrotation, and anorectal malformation (ARM). The initial diversion was done in four cases, and primary repair was done in eight cases. Two neonates died postoperatively due to septicemia. Conclusion: CAs are rare anomalies and often associated with other congenital malformations. Its association should be kept in mind during colostomy formation for high ARM. CAs can be managed successfully by primary anastomosis regardless of the location of atresia. Early diagnosis and intervention are essential for the survival of these neonates.
