Splenic injury after colonoscopy is extremely rare; however internists/gastroenterologists should be aware of this possible potentially fatal complication and its delayed and unspecific onset. Lorenz Theilmann, Ulrich Voehringer and Ahmed Abdel Samie* Department of Gastroenterology, HELIOS Hospital, Germany Case Presentation A 44 years old female was admitted to the hospital with Crohn’s disease involving the upper GI tract as well as the terminal ileum. Diagnosis had been attained 4 months before histologically by gastroduodenoscopy and MRI enterography and treatment with corticosteroids had been initiated. The patient was readmitted to complete staging including ileocolonoscopy which she previously had refused. Ileocolonoscopy was performed under conscious sedation using propofol and revealed active Crohn ́s disease of the distal ileum on a length of 10 cm. The entire colon showed normal appearance. These findings were confirmed by histology. The endoscopic procedure was uneventful. Progression of the scope up to the terminal ileum was achieved smoothly with no significant looping with a total procedure time of 12 min and withdrawal time of 8 min. The patient was asymptomatic and mobile following the procedure. However, 10 hr later she reported slight dizziness and unspecific abdominal discomfort. During the following night she complained about abdominal pain. Lab tests showed a drop of her hemoglobin to 7.4 g/dl. Ultrasound examination was performed demonstrating pathological findings in the left upper abdomen (Figure 1 and 2). Abdominal ultrasound revealed an enlarged spleen with hypoechoic areas at the upper splenic pole consistent with intrasplenic bleeding (Figure 1). In addition, free fluid was detected in the perisplenic abdominal cavity (Figure 2). Diagnostic aspiration of this fluid confirmed Intra-abdominal bleeding due to splenic injury. The patient was immediately transferred to the operating room, received transfusion of two packed red blood cells, and explorative laparotomy and splenectomy have been performed. Intraoperatively pronounced adhesions of the greater omentum (mainly in the left lower abdomen) have been documented. The spleen was partially avulsed with sub capsular hematoma and secondary rupture. The postoperative course was uneventful and the patient was discharged after five days having received triple vaccination against postsplenectomy infections according to the current guidelines. Treatment of Crohn's disease was resumed. Discussion Splenic injury due to colonoscopy is a rare complication and most patients have delayed symptoms. Less than 80 cases have been reported so far. In systematic reviews [1,2] two hypothetic mechanism of trauma have been suggested. Direct trauma by the endoscope being positioned in the left flexure, yet this mechanism of injury appears to be less frequent than excessive traction on the splenocolic ligament when advan","PeriodicalId":11275,"journal":{"name":"Diagnostic imaging","volume":"39 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74846057","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Ultasonographic indicators of carpal tunnel syndrome demonstrate reversibility following carpal tunnel release","authors":"Ryusuke Osada, Mineyuki Zukawa, Tomoatsu Kimura","doi":"10.15761/rdi.1000121","DOIUrl":"https://doi.org/10.15761/rdi.1000121","url":null,"abstract":"Background: The objective of the present study was to use ultrasound examination to determine the cross-sectional area (CSA) of the median nerve and quantify transverse sliding motion during finger movements in patients with carpal tunnel syndrome (CTS). Method: CSA and transverse sliding motion were compared between 15 cases with bilateral CTS (30 hands; 3 men, 12 women; average age: 65.7 years) and a control group (30 hands) of ageand sex-matched healthy individuals. Furthermore, 13 hands of 12 patients who underwent open carpal tunnel release (2 men, 10 women; average age: 62.3 years) were assessed and compared before and after surgery. Results: The mean CSA was larger in the CTS group (16.9 mm2) than in the controls (10.0mm2), whereas transverse sliding motion was significantly higher in controls (6.6 mm) than in the CTS group (4.9 mm). The 12 patients with CTS who underwent surgery showed a mean preoperative CSA of 19.1mm2 that declined significantly to 14.2 mm2 postoperatively, and the mean transverse sliding motion increased from 3.2 mm preoperatively to 5.0 mm postoperatively. Conclusion: Combining CSA and transverse sliding motion as observed in ultrasound examination can improve CTS diagnosis. Increased CSA and decreased transverse sliding motion noted at the median nerve in the wrists of patients with CTS are partially reversible by open carpal tunnel release.

Subject and Method: One hundred and fifty repeat CT examinations with an implementation of a CT dose reduction technique per examination were included. Percent of dose reductions compared with their prior CT examinations with standard CT protocols in terms of dose length product were calculated. Result: There were 95 examinations using scanning parameter optimization technique, 47 examinations using reduction of multiphase scanning and 8 examinations using limited scan range. Percent of dose reductions for scanning parameter optimization, reduction of multiphase scanning and limitation of scan range were 43.3%, 52.5%, and 39.1% respectively. Among the scanning parameter optimization, percent of dose reductions by lowering tube voltage, and lowering tube current were 47.9%, and 38.6%, respectively. Conclusion: The presented dose lowering protocols are simple and available in most modern CT scanners. Reduction of multiphase scanning shows highest dose reduction. All of these techniques do not depend on CT scanners but requiring special CT protocol tailored for the individual patient for optimal diagnostic quality in the optimization of patient dose in CT.
