Introduction Congenital saccular cysts are a rare entity. Herein we present our experience with congenital saccular cysts in a tertiary pediatric institution. There have been 2 cases of congenital saccular cysts in the past 20 years. Case Series Case 1: A female neonate was born full term via normal vaginal delivery. Stridor, grunting and retractions were noted immediately at birth. She underwent microlaryngobronchoscopy and endoscopic marsupialization of left saccular cyst on day 2 of life. She was discharged two weeks later on room air. Case 2: A male neonate was born full term via emergency C-section for non-reassuring fetal status. Borderline saturations were noted at birth and intubation was attempted and failed twice. He underwent microlaryngobronchoscopy and endoscopic marsupialization of right saccular cyst on day 0 of life. He was discharged two weeks after on room air. Discussion Congenital saccular cysts are a rare cause of infant stridor. Their potential to cause significant airway compromise and frequent delay in diagnosis make them a possibly lethal condition. Some report mean time of symptom onset to diagnosis was 4 months. For our cases, the prompt availability of endoscopic guidance allowed for early diagnosis and treatment. Surgery is the mainstay of treatment. Most modern cases advocate for endoscopic excision with CO2 laser or cold instruments. Endoscopic marsupialization with cold instruments was used for our cases. The risk of recurrence for congenital saccular cysts has been found to be 43.4%, with case reports detailing recurrence as early as two weeks. For our patients, no recurrence has been noted 12 months after treatment. Conclusion More studies are needed to evaluate the best surgical treatment for cysts especially in view of their high recurrence rate. Though small, our institute’s experience suggests that endoscopic marsupialization with cold instruments is an effective surgical treatment for congenital saccular cysts.
