ABSTRACT
Intestinal malrotation is a congenital anomaly caused by incomplete rotation or absence of rotation of the primitive intestine along the axis of the upper mesenteric artery during embryonic development. Embryonic development and its anatomical variations were described by Dott in 1923. Intestinal malrotation is a rare condition among adults - prevalent in a mere 0.0001% to 0.19% of the population -, and it may be associated with other anatomical deformities. It can be asymptomatic or manifest with varying intensity, from obstruction to necrosis of intestinal segments. In general, this abnormality is diagnosed in the first year of life; however, symptomsmay appear later in life,making diagnosis in adults difficult on account of non-specific symptoms. In the present study, we report a case of intestinal malrotation associated with chronic non-specific symptoms progressing to mesenteric angina. (AU)

OBJETIVO: descrever a experiência na abordagem dos doentes com abdome agudo por obstrução por IB, desde o diagnóstico até o tratamento definitivo. MÉTODOS: estudo retrospectivo incluindo todos os casos de IB tratados em um período de 23 anos. De acordo com a abordagem cirúrgica realizada, os pacientes foram divididos em dois grupos (1) enterolitotomia com colecistectomia no segundo momento; e (2) enterolitotomia, colecistectomia e abordagem da fístula. RESULTADOS: Doze pacientes foram incluídos, sendo 11 mulheres (91,6%), com média de idade de 72,2 anos. Todos os pacientes apresentavam doenças associadas, principalmente hipertensão arterial sistêmica (75%). Dois pacientes não apresentavam sintomas significativos de obstrução intestinal. O diagnóstico de IB foi realizado em seis pacientes (50%) antes da laparotomia. O grupo 1 foi constituído de oito pacientes e o grupo 2 de quatro, e a morbidade foi, respectivamente, 33,3% e 8,3%. A mortalidade foi 16,6% (um paciente de cada grupo). CONCLUSÃO: O manejo do IB deve ser individualizado. O tratamento da obstrução mediante remoção do cálculo biliar por enterotomia proximal é a escolha inicial para o tratamento do IB. A colecistectomia e a correção da fístula bilioentérica podem ser realizadas juntamente com a remoção do cálculo, no entanto, em pacientes com comorbidades significativas, esses procedimentos devem ser realizados posteriormente.
OBJECTIVE: To perform a systematic review of the history, available image exams and clinical approach to the diagnosis and treatment of gallstone ileus. METHOD: Retrospective study in a university hospital including all cases of SBO treated over a period of 23 years. According to the surgical treatment the patients were divided into two groups: (1) enterolithotomy with cholecystectomy performed later (two-stage surgery); and (2) enterolithotomy, cholecystectomy and fistula closure (one-stage surgery). RESULTS: Twelve patients were included in the study, including 11 females (91,6%), with a mean age of 72.2 years. All patients presented associated diseases, mainly arterial hypertension (75%). All except one patient had multiple SBO symptoms. Gallstone ileus diagnosis was achieved in six patients (50%) before laparotomy. There were 8 patients in group 1 and 4 in group 2, and the morbidity was, respectively, 33.3% and 8.3%. Overall mortality was 16.6% (one patient in each group). CONCLUSIONS: Gallstone ileus should be suspected in the elderly with SBO symptoms. Early diagnosis can reduce post-operative complications. Treatment is urgent laparotomy, and surgical treatment must be individualized for each case. The majority of patients in this study were treated with enterolithotomy, with cholecystectomy being performed later in two symptomatic patients.
