End-colostomy diverticulitis with parastomal phlegmon: A case report.

RATIONALE: Acute colonic diverticulitis is a well-known surgical emergency, which occurs in about 10 percent of patients known for diverticulosis. PATIENT CONCERNS: The case of a 77-year-old woman is reported, with past history of abdominoperineal resection with end-colostomy for low rectal adenocarcinoma, and who developed an acute colonic diverticulitis in a subcutaneous portion of colostomy with parastomal phlegmon. DIAGNOSES: Initial computed tomography imaging demonstrated a significant submucosal parietal edema with local fat tissues infiltration in regard of 3 diverticula. INTERVENTIONS: A two-step treatment was decided: first a nonoperative treatment was initiated with 2 weeks antibiotics administration, followed by, 6 weeks after, a segmental resection of the terminal portion of the colon with redo of a new colostomy by direct open approach. OUTCOMES: Patient was discharged on the second postoperative day without complications. Follow-up at 2 weeks revealed centimetric dehiscence of the stoma, which was managed conservatively until sixth postoperative week by stomatherapists. LESSONS SUBSECTIONS: Treatment of acute diverticulitis with parastomal phlegmon in a patient with end-colostomy could primary be nonoperative. Delayed surgical treatment with segmental colonic resection was proposed to avoid recurrence and potential associated complications.

Occurrence of aortic aneurysms in 5 cases of Wiskott-Aldrich syndrome.

Aortic aneurysms are a rare condition in children. Here we report the occurrence of aortic aneurysms in 5 children with Wiskott-Aldrich syndrome (WAS). Three patients had a WAS score of 4, and 2 patients had a WAS score of 5, but autoimmunity was only present in 1 patient. Discovery was fortuitous in 4 cases after chest radiography or thoracic or abdominal computed tomography, which was performed to investigate unrelated symptoms; in 1 patient, thoracic pain was an alerting sign. Age at diagnosis was 10 to 16 years. Aneurysms were confined to the thoracic aorta in 4 cases and to the abdominal aorta in 1 case and were from 2 to 6 cm in size. Aortic surgery was successfully performed on the single symptomatic patient. Two other patients are alive: there has been a low progression of the aneurysm 15 years after hematopoietic stem cell transplantation in 1 patient and no evidence of progression after 12 years of follow-up without hematopoietic stem cell transplantation in the second patient. Two patients died 2 and 4 years after diagnosis from unrelated complications. A systematic retrospective search of 33 other patients with WAS for whom imaging material was available did not reveal the presence of aortic aneurysms. This unusual frequency of aortic aneurysm found in patients with WAS (5 of 38) indicates that aneurysm can be an underdiagnosed complication of WAS. It is presently unclear whether it is caused by an infectious and/or autoimmune/inflammatory process. Therefore, we suggest that aneurysms of large vessels should be systematically searched for in patients with WAS.
