Spleen preservation during distal pancreatectomy (SpDP) can be accomplished by a variety of surgical approaches, but the impact on spleen function is unknown. This study aimed to compare spleen volume, function and complications between patients who underwent vessel sparing (VSDP) vs. vessel ligating (Warshaw, WDP) SpDP. All patients who underwent SpDP at the Toronto General Hospital from 2006 to 2015 were included. Primary outcomes were pre- and post-operative spleen volumes and contrast enhancement on CT, hematologic parameters, and spleen-related complications. 82 patients underwent SpDP with median follow up of 20.4 months. Splenic volumes were able to be calculated on 44 patients (VSDP n = 8, WDP n = 36). There was no difference between WDP and VSDP in operative duration, blood loss, hospital length of stay, or Clavien-Dindo ≥3 complication rate. Spleen volumes did not differ from baseline in either group. On postoperative imaging more WDP patients had areas of splenic hypoperfusion (p = 0.032). These differences resolved by 3 months after surgery, there were no instances of long term infectious or bleeding complications related to poor splenic function or gastric varices. Both WDP and VSDP achieve splenic preservation. Neither technique resulted in clinically apparent spleen related complications. There is no difference in splenic volume and function in the short/long term. [ABSTRACT FROM AUTHOR]

Uveal melanoma (UM) is a rare malignancy with a propensity for metastasis to the liver. Systemic chemotherapy is typically ineffective in these patients with liver metastases and overall survival is poor. There are no evidence-based guidelines for management of UM liver metastases. The aim of this study was to review the evidence for management of UM liver metastases. A systematic review of English literature publications was conducted across Ovid Medline, Ovid MEDLINE and Cochrane CENTRAL databases until April 2019. The primary outcome was overall survival, with disease free survival as a secondary outcome. 55 studies were included in the study, with 2446 patients treated overall. The majority of these studies were retrospective, with 17 of 55 including comparative data. Treatment modalities included surgery, isolated hepatic perfusion (IHP), hepatic artery infusion (HAI), transarterial chemoembolization (TACE), selective internal radiotherapy (SIRT) and Immunoembolization (IE). Survival varied greatly between treatments and between studies using the same treatments. Both surgery and liver-directed treatments were shown to have benefit in selected patients. Predominantly retrospective and uncontrolled studies suggest that surgery and locoregional techniques may prolong survival. Substantial variability in patient selection and study design makes comparison of data and formulation of recommendations challenging. [ABSTRACT FROM AUTHOR]
