RESUMO
Unlike acute diverticulitis, giant diverticulum larger than 4 cm is a rare entity with few cases described in the literature. We present a case of a 66-year-old male patient diagnosed with colonic diverticulosis. He presented to the emergency department with symptoms of acute abdomen and was diagnosed by CT scan with a 13x14 cm giant diverticulum showing signs of complication. Given the findings, an urgent surgical intervention was decided, and diverticulectomy at the diverticular neck was performed using an endostapler. The etiology of giant diverticula is related to a mechanism of one-way valve at the diverticular neck. Diagnosis poses a challenge as the clinical presentation is nonspecific. The imaging modality of choice is CT scan, which reveals a large cystic image dependent on the sigmoid colon. Definitive treatment is surgical, either by resecting the affected segment including the lesion or by performing a simple diverticulectomy in uncomplicated cases.

Atraumatic splenic rupture, an infrequent surgical emergency, constitutes a life-threatening situation. The lack of a traumatic background makes it difficult to suspect. We present a case of a 45-year-old woman, with history of bariatric surgery, referred to our emergency due to 3 weeks long abdominal and lumbar pain, in shock. Imaging diagnosis of splenic rupture, emergent surgery was performed with atypical findings and good evolution. The bibliographic review, background and surgical findings allowed to postulate causality in this unusual presentation. Despite its low frequency, this pathology involves significant mortality and must be present in the patient in shock in the emergency room.
La rotura esplénica atraumática, una emergencia quirúrgica infrecuente, constituye una situación de riesgo vital. La falta de antecedente traumático dificulta su sospecha. Presentamos el caso de una mujer de 45 años, con antecedente de cirugía bariátrica, remitida a nuestro servicio de urgencias por dolor abdominal y lumbar de 3 semanas, en shock. Con el diagnóstico imagenológico de rotura esplénica, se realizó cirugía emergente, con hallazgos atípicos, y la paciente tuvo una buena evolución. La revisión bibliográfica, los antecedentes y los hallazgos quirúrgicos permitieron postular la causalidad en esta inusual presentación. Pese a su poca frecuencia, esta patología comporta una mortalidad importante y debe tenerse presente ante un paciente en shock en la sala de urgencias.
