Elective hepatic resection is feasible and safe in a regional centre.

BACKGROUND: Hepatic resectional surgery remains a highly specialized area of general surgery usually reserved for completion at tertiary metropolitan referral centres. Port Macquarie, on the Mid North Coast of New South Wales, is the only regionally based hospital offering surgery of this nature in mainland Australia. The purpose of this study is to review the data for patients undergoing hepatic resectional surgery in this non-metropolitan centre in order to illustrate that these operations can be carried out safely in a regional setting with comparable results to tertiary-level centres. METHODS: A retrospective review of consecutive patients undergoing elective hepatic resections at Port Macquarie from February 2008 to 31 October 2015 was completed. Pre-morbid patient clinical and demographic factors, histopathological details, post-operative complications, survival and mortality data were all noted. RESULTS: A total of 66 consecutive elective liver resections were performed during the study period. Metastatic colorectal cancer was the most commonly observed pathology (n = 33, 50.0%). The 90-day mortality was 4.5% (n = 3) whilst 17 patients (n = 17, 25.8%) experienced major complications (Clavien-Dindo grade 3 or 4). The median overall survival following hepatectomy for colorectal metastases was 48 months (95% confidence interval 37-59 months). CONCLUSION: Our study shows excellent morbidity, mortality and survival for hepatic resectional surgery performed in a regional centre and is comparable data to major metropolitan centres. Our study confirms that major hepatic resectional surgery in this setting is safe and effective.

A systematic review and meta-analysis of the randomized controlled trials on adjuvant intraperitoneal chemotherapy for resectable gastric cancer.

BACKGROUND: The purpose of this systematic review and meta-analysis was to determine the effectiveness and safety of adjuvant intraperitoneal chemotherapy for patients with locally advanced resectable gastric cancer. METHODS: Studies eligible for this systematic review included those in which patients with gastric cancer were randomly assigned to receive surgery combined with intraperitoneal chemotherapy versus surgery without intraperitoneal chemotherapy. There were no language restrictions. After independent quality assessment and data extraction, data were pooled for meta-analysis. RESULTS: Thirteen reports of randomized controlled trials (RCTs) were included for quality appraisal and data extraction. Ten reports were judged to be of fair quality and subjected to meta-analysis. A significant improvement in survival was associated with hyperthermic intraoperative intraperitoneal chemotherapy (HIIC) alone (hazard ratio [HR] = 0.60; 95% CI = 0.43 to 0.83; p = 0.002) or HIIC combined with early postoperative intraperitoneal chemotherapy (EPIC) (HR = 0.45; 95% CI = 0.29 to 0.68; p = 0.0002). There was a trend towards survival improvement with normothermic intraoperative intraperitoneal chemotherapy (p = 0.06), but this was not significant with either EPIC alone or delayed postoperative intraperitoneal chemotherapy. Intraperitoneal chemotherapy was also found to be associated with higher risks of intra-abdominal abscess (RR = 2.37; 95% CI = 1.32 to 4.26; p = 0.003) and neutropenia (RR = 4.33; 95% CI = 1.49 to 12.61; p = 0.007). CONCLUSIONS: The present meta-analysis indicates that HIIC with or without EPIC after resection of advanced gastric primary cancer is associated with improved overall survival. However, increased risk of intra-abdominal abscess and neutropenia are also demonstrated.
