RESUMO
Introduction: Cholelithiasis is a prevalent disease in Chile. Therefore, there is sufficient evidence regarding the results of cholecystectomy in adults; however, information in pediatric population is scarce. The aim of this study is to report the results of a series of pediatric patients undergoing surgery for cholelithiasis, in terms of postoperative morbidity (POM). Material and Methods: Retrospective case series. All patients undergoing laparoscopic cholecystectomy for cholelithiasis in the period 2004 to 2013, in the Department of Surgery of Hospital de Puerto Montt, Chile, were included. The main outcome variable was POM. Other variables of interest were cause of consult, coexistence of choledocholithiasis, concomitant diseases, nature of surgery, hospital stay and mortality. Descriptive statistics were used to calculate percentages, measures of center tendency and dispersion. Results: 71 patients, with a median age of 13 years, 84.5 percent female, were operated. POM was 1.4 percent (one case of hemoperitoneum that required reoperation, Dindo-Clavien IIIb). The most frequent cause of consultation was biliary colic (95.8 percent of cases). Coexistence of choledocholithiasis was determined in 6 cases (8.5 percent). The most common concomitant disease was familiar microspherocytosis (4 cases, 5.6 percent). The surgery was elective in 62 patients (87.3 percent). Median hospital stay were 2 days. The serie has no mortality. Conclusion: The observed results are comparable with those from other series of laparoscopic cholecystectomy in pediatric patients.
Introducción: La colelitiasis es una enfermedad prevalente en Chile; por ende, existe suficiente evidencia respecto de los resultados de la colecistectomía en población adulta; sin embargo, la información en población pediátrica es escasa. El objetivo de este estudio, es reportar los resultados de una serie de pacientes pediátricos, intervenidos quirúrgicamente por colelitiasis, en términos de morbilidad postoperatoria (MPO). Material y Método: Serie de casos retrospectiva. Se incluyeron todos los pacientes pediátricos colecistectomizados vía laparoscópica en el Servicio de Cirugía del Hospital de Puerto Montt, Chile; en el período 2004 y 2013. La variable resultado fue MPO. Otras variables de interés fueron causa de consulta, coexistencia de coledocolitiasis, enfermedades concomitantes, carácter de la cirugía, estancia hospitalaria y mortalidad. Se utilizó estadística descriptiva con cálculo de porcentajes, medidas de tendencia central y dispersión. Resultados: Se intervinieron 71 pacientes, con una mediana de edad de 13 años; 84,5 por ciento de sexo femenino. La MPO fue de 1,4 por ciento (un caso de hemoperitoneo que requirió reoperación; Dindo-Clavien IIIb). La causa de consulta más frecuente fue el cólico biliar (95,8 por ciento de los casos). Se determinó coexistencia de coledocolitiasis en 6 casos (8,5 por ciento). La enfermedad concomitante más frecuente fue microesferocitosis familiar (4 casos; 5,6 por ciento). La cirugía fue electiva en 62 pacientes (87,3 por ciento). La mediana de la estancia hospitalaria fue 2 días y no se reporta mortalidad. Conclusión: Los resultados observados son comparables con los de otras series de colecistectomía laparoscópica en pacientes pediátricos.

<b>Objectives: </b>Radon (<sup>222</sup>Rn) is a noble gas found in the water of hot spring spas (“onsen”).
