A retrospective study of histological outcome for IPMN after surgery in Lausanne, Switzerland: A case series.

ABSTRACT: Introduction:Intraductal papillary mucinous neoplasm (IPMN) is a 21st century concept and its management is still controversial. Strong guidelines suggest that surgery is the safest way to prevent malignant evolution. Though the risk of neoplasia is still debated, high-morbidity and mortality surgery must be proposed for high-risk patients to prevent malignant and most likely fatal pancreatic neoplasia. Methods:The aim of this study was to analyze histological results of patients who underwent operation for IPMN under the Sendai and Fukuoka guidelines. From January 2005 to August 2016, 491 consecutive patients who underwent pancreatic resection in Lausanne University Hospital were analyzed, including 18 IPMN with surgical indication according to the Sendai and Fukuoka criteria. Results:Thirteen (68.4%) patients had benign histopathology after surgery (the non-malignant group). Of the patients with malignant pathology, four (21%) had high-grade dysplasia and two (20.1%) had invasive carcinoma (the malignant group). The median patient age (p = 0.011) and preoperative Carbohydrate Antigen 19-9 (CA19-9) (p = 0.030) were significantly higher in the malignant group than in the non-malignant group. Discussion:The use of the current criteria is adequate, but it may be resulting in surgery on excessive numbers of patients with IPMN. A modern decision-making strategy should be based on clinical features, precise imaging data, and biological markers.

Project description:PurposeThis study aimed to determine the long-term level of pain after surgical treatment of one or more symptomatic rib fracture nonunions. Secondary aims were to evaluate the occurrence of adverse events, satisfaction, and activity resumption. The final aim was to assess the association between pain and the presence of bridging callus at the nonunified fracture. Hypothesized was that thoracic pain would diminish after surgery.MethodsThis retrospective case series included adults who underwent surgery for a symptomatic rib fracture nonunion from three hospitals. Symptomatic nonunion was defined as persistent pain associated with nonbridging callus of ≥1 rib fractures on a chest CT scan at ≥3 months after the initial injury. Patients completed questionnaires about pain, satisfaction, and activity resumption ≥3 months postoperatively.ResultsThirty-six patients (26 men, 10 women), with a median age of 55 (P25-P75 49-62) years and 169 acute rib fractures were included. Nonunion occurred in 98 (58%) fractures of which 70 (71%) were treated surgically. After a median of 11 months (P25-P75 7-21), 13 (36%) patients reported severe pain, in contrast to 26 (72%) preoperatively. Patients who underwent intercostal neurectomy or neurolysis in addition to surgical stabilization less often reported pain reduction. Twenty-six (72%) had postoperative complications, for which 12 (33%) underwent additional surgery, mostly for persistent pain. The majority (n = 27; 75%) was satisfied with their functional recovery. Of patients who had paid work pre-trauma, 65% had resumed working.ConclusionMost patients reported less pain and better daily functioning after surgical stabilization of symptomatic rib fracture nonunions, although causality cannot be proven with this retrospective case series. Additional intercostal nerve treatment was not associated with pain relief. Despite surgery-related complications being common, patient satisfaction was high.Level of evidenceLevel V.Study typeTherapeutic.

Project description:PURPOSE:The Xen® Gel Stent (Allergan, Irvine, CA, USA) is a minimally invasive glaucoma surgery device implanted to reduce intra-ocular pressure (IOP) in glaucoma. The stents can fail to drain post-operatively due to scarring of the conjunctiva around the stent opening. Data on the success rates of revision surgery in patients with Xen stent failure are scarce. We present the first detailed report of the steps, outcomes and complications of Xen revision surgery with 12 months of follow-up data. METHODS:We share our experiences on the circumstances in which to perform Xen revision surgery, the steps of the surgery and the results of a retrospective interventional case series of all Xen revisions performed at a single centre from 2013 to 2018. RESULTS:A total of 151 Xen implants were inserted into eyes at our tertiary centre during the study period, of which 21 eyes (patients) underwent revision surgery. Mean pre-operative IOP was 26.1 (standard deviation 8.3) mmHg with the patient on two drops of anti-glaucoma medication. Four patients were excluded from the analysis due to incomplete data (medical records were unavailable for 2 patients; 1 patient died shortly after surgery; and 1 patient moved to another area). A non-functioning Xen implant was identified in another patient during revision surgery, and the procedure was converted to a trabeculectomy. The remaining 16 patients were included in the analysis, all of whom had a minimum follow-up of 12 months, with the longest follow-up being 4 years following revision surgery. Of these 16 patients, four required needling and 5-fluorouracil injection in the first 12 months following revision surgery, three required further glaucoma drainage surgery due to the failure of the revision surgery to control IOP in the first year and one suffered bleb-related endophthalmitis at the site of previous trabeculectomy surgery. Mean IOP at 12 months following revision surgery was 16.3 (standard deviation 3.7) mmHg on 0.7 drops of anti-glaucoma medication, which equates to a 37.5% reduction in IOP and a 65% reduction in the amount of IOP-lowering drops required. CONCLUSION:Our study shares experience on when to perform Xen revision surgery and the steps required. The results of our small cohort are the first in the literature and show that revisions can achieve promising IOP and medication reductions. Some patients still require needling in the post-operative period to optimise outcomes.
