Major and minor amputation rates were stable across England between 2003 and 2008, accompanied by a significant reduction in perioperative mortality. There were significant geographical variations in amputation rates, mortality rates and the below-knee : above-knee amputation ratio.

In conclusion free tissue transfer achieves successful wound healing in selected patients with diabetes and difficult to heal wounds that would have required amputation. Pre-operative optimisation of vascular supply and eradication of infection is key to success. Objective wound assessment scores and a clear multidisciplinary team (MDT) approach would improve patient care.

AIMTo compare outcomes in patients undergoing rectal resection by robotic total meso-rectal excision (RTME) vs laparoscopic total meso-rectal excision (LTME).METHODSStandard medical electronic databases such as PubMed, MEDLINE, EMBASE and Scopus were searched to find relevant articles. The data retrieved from all types of included published comparative trials in patients undergoing RTME vs LTME was analysed using the principles of meta-analysis. The operative, post-operative and oncological outcomes were evaluated to assess the effectiveness of both techniques of TME. The summated outcome of continuous variables was expressed as standardized mean difference (SMD) and dichotomous data was presented in odds ratio (OR).RESULTSOne RCT (ROLARR trial) and 27 other comparative studies reporting the non-oncological and oncological outcomes following RTME vs LTME were included in this review. In the random effects model analysis using the statistical software Review Manager 5.3, the RTME was associated with longer operation time (SMD, 0.46; 95%CI: 0.25, 0.67; z = 4.33; P = 0.0001), early passage of first flatus (P = 0.002), lower risk of conversion (P = 0.00001) and shorter hospitalization (P = 0.01). The statistical equivalence was seen between RTME and LTME for non-oncological variables like blood loss, morbidity, mortality and re-operation risk. The oncological variables such as recurrence (P = 0.96), number of harvested nodes (P = 0.49) and positive circumferential resection margin risk (P = 0.53) were also comparable in both groups. The length of distal resection margins was similar in both groups.CONCLUSIONRTME is feasible and oncologically safe but failed to demonstrate any superiority over LTME for many surgical outcomes except early passage of flatus, lower risk of conversion and shorter hospitalization.
