[Modern interdisciplinary management of a uretero-iliac artery fistula (case report)]. / Modernes interdisziplinäres Management einer uretero-iliakalen Fistel (Fallbericht).

INTRODUCTION: Abnormal links between the arterial system and other luminal systems are a challenge to those in charge of their adequate diagnostic and therapeutic management. OBJECTIVE: Scientific case report on an individual who underwent successful treatment combining vascular-surgical and interventional radiology techniques for a rare right uretero-iliac artery fistula based on personal clinical experience, a selective literature research and a detailed discussion of current recommendations for diagnostic workup and subsequent treatment. CASE CHARACTERISTICS: A 79-year-old patient was admitted with haematuria : and bladder tamponade : in the presence of bilateral actinic ureteral strictures secondary to neoadjuvant radiochemotherapy followed by abdominoperineal rectum exstirpation due to suprasphincteric rectal cancer (ypT3ypN0M0). Laboratory tests revealed anaemia; transabdominal ultrasound demonstrated bilateral urinary retention. A complementary CT scan did not reveal any manifest bleeding resulting from intermittent haemorrhage. SURGICAL PROCEDURE: Initially, the bladder haematoma was removed and ureteral catheters were changed. Due to endoluminal bleeding in the right ureter, a combined procedure was initiated, involving a vascular-surgical approach (access to the right femoral artery, ultimate disobliteration and intimal refixation in the right superficial femoral artery due to dissection) and an interventional radiology approach (insertion of an Amplatzer [AMPLATZER™Vascular Plug II; St. Jude Medical, Saint Paul, Minnesota, USA] into the right internal iliac artery and iliac stenting by a cross-over manoeuvre from the left femoral access site) although no acute bleeding was detected in the CT scan (but acute haemorrhage from the right ureteric ostium was confirmed during cystoscopy). CLINICAL COURSE: The patient stabilised in due time in response to periinterventional treatment in the ICU. He was discharged on the 15th day after surgery without evidence of recurrent haemorrhage. SUMMARY: In the presented case, this promptly initiated (vascular-surgical and interventional radiology) hybrid operation was absolutely indicated, being the approach with the best prospects for recurrent arterial bleeding with clinical manifestation of haematuria and haemorrhage within the urinary bladder due to a uretero-iliac artery fistula. CONCLUSION: Today, a minimally invasive approach with stenting is the method of choice in the sequential, urgent management of a potentially life-threatening uretero-iliac fistula in the presence of arterial endoluminal bleeding and an imminent haemorrhagic shock.

Is a one-step sleeve gastrectomy indicated as a revision procedure after gastric banding? Data analysis from a quality assurance study of the surgical treatment of obesity in Germany.

BACKGROUND: Since 1 January 2005, the outcomes of bariatric surgeries have been examined in Germany. All data are registered prospectively in cooperation with the Institute of Quality Assurance in Surgery at Otto-von-Guericke University Magdeburg. METHODS: Data are collected in an online data bank. Data collection began in 2005 for the results of gastric banding (GB) and in 2006 for sleeve gastrectomies (SGs). In addition to primary bariatric operations, data regarding the complications of revision procedures and redo operations have been analyzed. Participation in the quality assurance study is required for all certified centers in Germany. RESULTS: SGs are a popular redo operation after failed gastric banding. Using the German Bariatric Surgery Registry, we analyzed data from 137 SGs that were used in a one-step approach after GB and 37 SGs that were used in a two-step approach. Leakage rates for primary SGs dropped to 1.9 %. The incidence of leakage after a one-step SG after GB is significantly higher (4.4 %) than for a two-step approach (0 %). CONCLUSION: SGs are popular procedures after failed GB in Germany, but the complication rates for one-step band removal are higher than for a two-step approach. After examining the data, we suggest performing band removal and SG as a two-step procedure. Further analysis is necessary to evaluate the optimal time period between band removal and SG. Follow-up investigations must be performed to determine if SG is an effective and safe option after GB.

Positive identification of cremains recovered from an automobile based on presence of an internal fixation device.

We report on the use of a surgically implanted device, an EBI osteostimulator, as a means of establishing the identification of a homicide victim. The use of such an appliance for securing positive identification has not been previously reported. Additionally we stress the importance of intensive and accurate excavation at scenes involving intense burning where the potential for non-skeletal contaminants is high.
