Diagnostic and therapeutic interventional radiology techniques in 41 patients with complications of pancreatic inflammatory disease (noninfected pseudocyst, infected pseudocyst, phlegmon, abscess, hemorrhagic pancreatitis) are described. Computed tomography or ultrasound-guided aspiration or percutaneous pancreatic ductography enabled specific diagnoses in 43 of 45 patients (96%). In almost half the patients, diagnostic aspiration with 22-gauge needles was unsuccessful due to viscous contents or firm cavity walls. Single-step needle aspiration of noninfected pseudocysts was successful in only three of ten patients (30%). Catheter drainage cured six of seven noninfected pseudocysts (85.7%) and seven of nine infected pseudocysts (77.7%). Pancreatic phlegmons were aspirated in five patients to exclude secondary infection and help determine the need for surgery. Pancreatic abscesses were drained successfully in nine of 13 patients (69.2%); temporizing benefit was achieved in the other four who eventually underwent surgery in improved condition. Early diagnosis of the complications of pancreatitis may be established almost uniformly, and at least 70% of patients with infected or noninfected pseudocysts and pancreatic abscesses may be cured by nonoperative drainage.

The hfioUS probe allowed in this study a precise detection of the tumor and a detailed discrimination between normal, pathological and edematous tissue in all 22 cases.

Introduction Instabilities of the thumb carpometacarpal (CMC) joint, caused by idiopathic ligamentous hyperlaxity, trauma or other conditions may lead to pain, functional impairment and eventually osteoarthritis. Several techniques have been described to enhance stability of the CMC 1. The aim of this study was to evaluate postoperative outcomes after CMC 1 joint stabilization using a soft-tissue procedure in patients with chronic instability. Materials and methods This study was designed as a retrospective study with a single follow-up visit after a minimum of 1 year postoperatively. All patients who underwent stabilization of the CMC 1 with an abductor pollicis longus (APL) tendon strip for chronic, habitual instability were reassessed using clinical examination, dedicated outcome scores [Visual Analogue Scale (VAS); The Disability of the Arm, Shoulder and Hand (DASH) score; Nelson score; Kapandji opposition score], grip and pinch strength measurements, and radiographic examination. Results 12 patients (15 operated thumbs) with a mean age at surgery of 23.2 (± 9.3) years were included after a mean followup period of 3.5 (± 1.3) years. The postoperative outcomes indicated excellent results, with a mean DASH score of 13.3 (± 11.3), VAS 1.1 at rest (and 2.8 during stress) and Nelson score of 87.7 (± 11.3). Postoperative grip, pinch strength and passive stability were not significantly different between operated and non-operated sides (p = 0.852; p = 0.923 and p = 0.428, respectively). We observed one case of recurrent instability besides no other complications. However, patients with trapezium hypoplasia (5 of 12) were more prone to signs of radiographic instability during stress testing. Conclusions Thumb carpometacarpal stabilization with an APL tendon strip yielded excellent clinical outcomes and low morbidity in the mid-term. However, long-term follow-up is needed to assess specifically whether patients with trapezium hypoplasia may be more prone to clinical symptom recurrence than those with normal anatomy.
