“…Despite its high sensitivity, MRCP is not routinely performed in acutely ill patients most of all because of longer time of acquisition and insufficient panoramicity. is technique has a sensitivity of 97.7% for gallstone detection, higher than abdominal XR (40-70%), CT scan (90-93%), and even than US (95%), especially in cases of isoattenuating and radiolucent stones that can be missed at abdominal XR and CT, or even in cases of very small ones (<3 mm) [25,26].…”

“…is technique may arguably be useful in selected cases of GI with the potential to further improve diagnostic yield for noncalcified calculi due to the excellent discrimination of fluid from gallstones, the latter appearing on T2 weighted images as signal voids in the context of the high-signal fluid. Moreover, if sufficient fluid is present in a collapsed cholecystoenteric fistulous tract, it may be delineated on MR images [2]: in their work, Liang and colleagues [25] concluded that MR was more sensitive than CT in detecting and accurately describing the fistula anatomy (100%) ( Figure 13).…”

“…Furthermore, MRCP together with CT may play a potential role in the management of chronic stones inside the gallbladder, helping in estimating the tendency to fistulation towards the bowel [25]: gallstone size greater than 2 cm, loss or blurring of the fat plane between the gallbladder and duodenum, patients over 70 years old, and previous common bile duct endoscopic basket lithotomy have been identified as possible risk factors for bilioenteric fistula forming.…”

Gallstone ileus is a dramatic complication of gallstone disease, uncommon but not exceptional in a busy emergency department. It represents a cause of mechanical intestinal obstruction, which predominantly occurs in elderly and frail patients; this contributes to the high morbidity and mortality rates associated with this condition. The modern radiologist is frequently asked to determine the cause of bowel obstruction and should be aware of the most pictorial features of this unusual disease. Broadly speaking, abdominal radiography and ultrasonography alone are limited in detecting the cause of bowel obstruction, but the sensitivity for the preoperative diagnosis of gallstone ileus may be improved by combining the findings obtained by both techniques. Computed tomography is the modality of choice for the diagnosis of this disease: it may accurately describe the number, size, and location of migrated gallstones and the exact site of bowel obstruction, providing a detailed preoperative planning. Magnetic resonance imaging may be used in selected cases for an exquisite anatomic definition of the fistulous communication.

“…The most common site of gallstone impaction has been reported as terminal ileum and ileocecal valve. Less frequent localizations have been reported as jejunum, stomach, duodenum and colon [5]. In our case, the stone was localized in the jejunum.…”

Gallstone ileus (GI) is an unusual but serious complication of biliary stone and it is caused by a fistula between the bile ducts and stomach, duodenum or colon. Gallstone that reaches the intestinal tract can be cause ileus. Early diagnosis with imaging modalities (such as computed tomography) and treatment of ileus are of great importance for survival. In addition, accurate diagnosis of underlying cause of the ileus is also important because it will guide the surgeon.We present a 73-year old patient with gallstone ileus preoperatively diagnosed with computed tomography (CT). CT showed gastric distention, dilated duodenal and jejunal small bowel loops, a calculus in the jejunal segment of the small bowel and enteral contrast medium reflux into the fistula tract and bile ducts.Pam Med J 2018;11(2):161-163 Key words: Gallstone ileus, computed tomography, complication, small bowel obstruction ÖzetSafra taşı ileusu, safra yolu taşlarının nadir ancak ciddi bir komplikasyonu olup safra yolları ile mide, duodenum veya kolon arasındaki fistül nedeniyle oluşur. İntestinal sisteme ulaşan safra taşı ileusa neden olabilir. Görüntüleme yöntemleriyle (Bilgisayarlı tomografi gibi) safra taşı ileusunun erken tanısı ve ileusun erken tedavisi sağkalım açısından büyük öneme sahiptir. Ayrıca, altta yatan ileus sebebinin doğru tanısı cerrahiye yol göstereceğinden önemlidir. Biz burada, bilgisayarlı tomografi (BT) ile operasyon öncesi safra taşı ileusu tanısı konulan 73-yaşında bir hasta sunuyoruz. BT'de midede distansiyon, duodenal ve jejunal ince barsak anslarında dilatasyon, jejunumda taş ve oral kontrast maddenin fistül traktına ve safra yollarına reflüsü gösterilmektedir.

Gallstone Ileus: An Uncommon Cause of Acute Abdomen

Gallstone ileus is a rare cause of acute abdomen, representing less than 1% of intestinal obstruction. It is due to mechanical small bowel obstruction (SBO) by a migrated gallstone. we report this observation to illustrate the imaging findings especially in CT scan. A 62-year-old woman was admitted to emergency for acute bowel obstruction. The CT scan has confirmed jejunal bowel distension with fluid levels upstream endoluminal formation which was rounded and well limited, measuring 5 cm of long axis. This training was slightly hyperdense with hypodense areas of fat density. Moreover, there was aerobilia with multiple fistulas between the duodenum (D1) and gallbladder, which was empty. The triad of aerobilia, small bowel obstruction and migrant gallstone was suggestive of gallstone ileus diagnosis. The patient was operated with good evolution. Gallstone ileus is an uncommon presentation of gallstone disease. It is frequently observed in elderly patients with a history of cholelithiasis or cholecystitis. Early diagnosis is crucial and would avoid morbidity and mortality related to this disease. CT scan shows the classical triad of Rigler with pneumobilia, an ectopic stone and mechanical ileus. CT may improve the diagnosis providing important information regarding the exact number, size, and location of ectopic stones and the site of intestinal obstruction or direct visualization of a biliary-enteric fistula, to help clinicians in the therapeutic management of patients.
