RESUMO
INTRODUCTION AND IMPORTANCE: There are limited reports in the literature of radical surgical resection for pancreatic neuroendocrine carcinoma (PNEC). In patients with non-functioning PNEC (NF-PNEC) within the tail of the pancreas tumours can cause splenic vein thrombosis (SVT) and subsequent sinitral portal hypertension (SPH). Radical surgical resection in such patients with concomitant liver metastasis has not previously been reported. CASE PRESENTATION: We present a 67-year old female patient who presented with a large NF-PNEC within the tail of the pancreas with liver metastasis. We performed a distal pancreatectomy, splenectomy, partial gastrectomy and liver resection to achieve radical resecton. DISCUSSION: All patients with NF-PNEC within the tail of the pancreatic should be considered for radical surgical resection. In the presence of multi-visceral involvement and complications such as SVT and/or SPH multi-speciality surgical expertise is likely to be required. CONCLUSION: Radical multi-visceral resection for large NF-PNEC can be safely performed in the presence of SVT and SPH.
RESUMO
BACKGROUND: Pancreaticoduodenectomy is the only curative treatment option for patients with resectable ampullary adenocarcinoma (AA). Excellent disease free survival (DFS) can be achieved in patients with clear resection margins but it is poorly understood which patients are at increased risk of recurrence and hence would benefit from adjuvant chemotherapy. There is evolving evidence that the anatomical location of incomplete resection margins influences DFS in pancreatic adenocarcinoma. It is unknown if this also pertains to AA and therefore this study aimed to assess individual resection margin status and other predictors of DFS in AA. MATERIAL & METHODS: Consecutive patients undergoing pancreaticoduodenectomy for AA at our institution from 1996 to 2017 were analysed. Pancreas neck, posterior and superior mesenteric vein margins were assessed individually. Cox proportional hazards modelling was used to identify predictors of 5-year DFS. Factors with p < 0.1 on univariate analysis were included for multivariate analysis. RESULTS: Analysis of 104 patients revealed median OS and DFS of 56 and 34 months, respectively. Predictors associated with worse DFS on multivariate analysis were T3-stage (HR 3.6, p = 0.048), N1 (HR 2.9, p = 0.01) and N2 -stage (HR 3.6, p = 0.006), R1 status at the posterior margin (HR 3.0, p = 0.009) and a visible mass on CT (HR 2.0, p = 0.039). CONCLUSION: Routine histopathological assessment of individual resection margins may aid in predicting recurrence of AA. Future studies to assess if routine mesopancreas excision during pancreaticoduodenectomy can reduce the incidence of R1 status at the posterior margin are warranted.

OBJECTIVE: We assessed the use of ultrasound guided foam sclerotherapy (UGFS) to treat bilateral varicose veins either as synchronous or interval procedures. We specifically assessed total foam volume usage and its influence on early outcome and complications. METHODS: We reviewed our prospectively compiled computerised database of patients with bilateral varicose veins who have undergone UGFS. Duplex findings, foam volumes used and clinical outcome were assessed. RESULTS: One hundred and twelve patients had undergone UGFS for bilateral varicose veins. Sixty-one had bilateral UGFS (122 legs) and 51 had interval UGFS (102 legs). Seventy-eight percent bilateral and 60% interval procedures were for single trunk disease. Median foam volumes per treatment episode were: 17.5 mls bilateral, and 10 mls interval FS. At two weeks 81% of legs had complete occlusion after bilateral UGFS compared to 70% after interval UGFS. One patient in the bilateral UGFS developed transient visual disturbance. There was no systemic complications in the interval UGFS. CONCLUSIONS: Bilateral foam sclerotherapy treatment did not adversly affect vein occlusion rates and there was no significant difference in complication rates between the two groups. Bilateral UGFS can be safely performed in selected patient presenting with bilateral varicose veins.

OBJECTIVES: Deep vein thrombosis (DVT) is a serious complication of varicose vein surgery, with attendant risks of pulmonary embolization. Prospective duplex screening identifies DVT in 5% of patients compared to clinical incidence of approximately 1%. Universal duplex screening is costly, and the benefits of diagnosing subclinical DVT are unproven. This study evaluates whether a policy of using clinical indications (leg swelling) to determine the need for duplex imaging is safe after varicose vein surgery. METHODS: Patients undergoing varicose vein surgery over a 4-year period were studied. Postoperative venous duplex imaging was performed if leg swelling occurred within 6 weeks of surgery. Long-term follow-up was performed to detect any missed occurrence of clinical DVT or pulmonary embolism. RESULTS: A total of 411 patients had 491 leg operations with 80 bilateral procedures (27%); 29 patients with leg swelling underwent duplex imaging, 5 of whom had duplex-proven DVT. No patient without early clinical signs went on to develop clinical DVT on long-term follow-up. CONCLUSION: A policy of using clinical signs as a triage for duplex imaging detected all clinically significant DVTs and generated manageable workloads for our vascular laboratory.
