[Clinical Trial to Test the iFuse Implant System® in Patients with Sacroiliac Joint Syndrome: One Year Results]. / Klinische Studie zur Prüfung des iFuse Implant Systems® bei Patienten mit Iliosakralgelenksyndrom: 1-Jahres-Ergebnisse.

Background: This study reports one year post-operative monitoring of the efficacy and safety of iFuse Implant System® in patients with sacroiliac joint syndrome. Material and Methods: After 6 months of inadequate conservative treatment, patients with properly proven ISG syndrome were selected for surgery. The iFuse implants had a triangular profile and coating of porous titanium plasma spray and were used in the minimally invasive procedures. The procedure was performed under general anaesthesia and fluoroscopic control. In each case, three implants were placed. Results: 24 patients (22 f; 92 %; 54.9 ± 14 years) participated in the study. The operations were performed in 11 patients (46 %) on the left and in 13 patients (54 %) on the right. The mean operative time was 42.4 minutes (95 % CI: 35.6-49.3). The reduction in pain intensity on the VAS scale was 58 ± 11 mm (68 ± 7 %). The Oswestry score showed a median decrease of 44 percentage points (57 %). After 12 months, 15 patients (63 %) reported that they were taking no more painkillers. Conclusion: The minimally invasive treatment of patients with sacroiliac joint syndrome using the iFuse Implant System leads to significant analgesic effects over the period of one year; it also contributes significantly to improving the functioning of the patient.

[Redo procedures in patients with pancreatic left resection]. / Revisionseingriffe und Interventionen nach Pankreaslinksresektion.

BACKGROUND: Distal pancreatectomy is performed less frequently than pancreatic head resection. Secondary operations due to postoperative complications are surgically complex and demanding, hence often interdisciplinary approaches are pursued. We have analysed the indications and outcome of revision surgery and interventional procedures subsequent to pancreatic left resection. PATIENTS AND METHODS: Between 2001 and 2009 we prospectively evaluated 61 patients regarding demographic factors, hospital stay, diagnosis, closure technique, redo operations and interventions, morbidity and mortality. RESULTS: Major complications without redo procedures were observed in 4 (9 %) of 44 patients. 8 (13 %) patients underwent early (7 +/- 8 days) postoperative revision procedures. A significant in-crease in hospital stay and mortality appeared in this group. Interventional procedures (7 x CT-guided abscess drains, 1 x haemorrhage with angio-graphic coiling, 1 x transgastral stenting of a pseudocyst) were performed significantly later (22 +/- 11 days p. o., p < 0,01) in 9 (15 %) patients. CONCLUSIONS: Pancreatic fistulas and related complications represent the most common indications for revisions, but can usually be controlled by interventional procedures. In contrast to secondary surgery, interventional revisions do not significantly increase the length of hospital stay or mortality. There was no benefit of any certain closure technique of the pancreatic remnant.
