Frequency and clinical outcome of capsule retention during capsule endoscopy for GI bleeding of obscure origin

“…However, the most frequent side effect is undoubtedly the non-natural excretion (NNE) of the capsule due to a stricture or a tumor in the small bowel. The retrospective analysis of some series indicates that the incidence of NNE depends on the indication for the capsule exam: 0% in healthy controls [8] , 1.4% in obscure gastrointestinal bleeding [9][10][11][12][13] , 1.48% in suspected Crohn´s disease [14][15][16][17] , 5%-13% in known Crohn´s disease [17][18][19] and 21% in suspected small bowel obstruction [20] . In the vast majority of cases, capsule retention, regardless of its cause, is asymptomatic, being evidenced by the absence of excretion and confirmed by means of radiology.…”

“…This cause was consistent with that in the study of Chiefetz and Lewis [5] . In contrast, some authors have reported that NSAID-induced stricture was the major cause of capsule retention [6,7] . Recently, Mason et al [8] have reported that intestinal mass or radiation enteritis are the main causes of subacute small bowel obstruction.…”

“…Las complicaciones descritas para el procedimiento son bajas 31 , la más importante aunque infrecuente es la retención [32][33][34][35] . Las desventajas están dadas por su alto costo, la incapacidad de realizar acciones terapéuticas y de establecer con exactitud la relación causa y efecto, al no contar con un patrón de oro en lesiones que por sus características no requieren procedimiento terapéutico invasivo o biopsia (puntos rojos, angiodisplasias no sangrantes, lesiones protruidas inespecíficas de aspecto benigno).…”
