RESUMO

Introduction Endoscopic endonasal surgery has globally improved postoperative results in pituitary adenomas. Material and Methods We retrospectively analyzed 101 patients who underwent endonasal endoscopic surgery for pituitary adenomas in the period from 2016 to 2021. Data on epidemiological variables, preoperative radiological factors including tumor volume, tumor appearance, cavernous sinus invasion (modified Knosp scale), degree of extension according to the SIPAP (stands for the five directions in which a pituitary adenoma can extend: suprasellar, infrasellar, parasellar, anterior, and posterior) classification, and preoperative visualization of the healthy gland on magnetic resonance imaging (MRI) were collected as well as intra- and postoperative cerebrospinal fluid (CSF) leak. As variables of interest, data on the degree of tumoral resection and preservation of hormonal function were collected. Results Among the preoperative factors related to greater tumoral resection, we found a lesser tumoral extension according to the SIPAP scale, and the absence of a postoperative CSF leak had a statistically significant relation with greater hormonal preservation. Conclusion The SIPAP classification is a simple-to-measure preoperative radiological variable that could predict the extent of resection, and, conversely, the occurrence of a postoperative CSF leak has been associated with an inferior endocrinological outcome in this type of surgery.

RESUMO

INTRODUCTION: Congenital pouch colon (CPC) is a rare malformation. It causes variable dilatation of the colon associated with anorectal malformation (ARM), usually presenting a fistula towards the genitourinary tract. CASE REPORT: 2-day-old female patient, with no relevant medical history. She had abdominal distension and imperforate anus. She underwent colostomy. She had an irregular evolution with high colostomy debits. Contrast imaging studies were performed, which demonstrated an erroneous exteriorization of the jejunal loop. She underwent an exploratory open surgery, which confirmed the previous diagnosis and incidentally found colonic agenesis, with ileum entering in a pouch of 6 cm of diameter that connects with the bladder. DISCUSSION: CPC is a common pathology in certain eastern countries and extremely rare in western countries. In Ecuador, no records of reported cases were found. A correct pre-surgical analysis of ARM patients should be carried out to achieve an adequate planning and surgical approach, thus reducing morbidity and mortality.


INTRODUCCION: La bolsa colónica congénita (BCC) es una malformación poco común en la que se produce una dilatación variable del colon asociada a malformación anorrectal (MAR), generalmente presenta una fistula hacia el tracto genitourinario. CASO CLINICO: Paciente femenino de 2 días de vida, sin antecedentes médicos de relevancia, presenta distensión abdominal y ano imperforado, es sometida a colostomía, presenta evolución irregular con débitos altos a través de la colostomía, se realizan estudios contrastados de imagen donde se observa exteriorización errónea de asa de yeyuno, se somete a laparotomía exploratoria donde se comprueba lo descrito y además se reporta como hallazgo incidental agenesia colónica con desembocadura del íleon en una bolsa de 6 cm de diámetro que se conecta con la vejiga. DISCUSION: La BCC es una patología común en ciertos países orientales y extremadamente rara en países occidentales; en Ecuador, no se encontraron registros de casos reportados. Se debe realizar un correcto análisis prequirúrgico de los pacientes con MAR para conseguir una adecuada planificación y abordaje quirúrgico disminuyendo con ello la morbimortalidad en el paciente.
