Peak wall stress can be calculated from routinely performed CT scans and may be a better predictor of risk of rupture than AAA diameter on an individual patient basis.

A centralized approach facilitated high volume experience in a single centre with an increase in the completeness of surgical excision rates and a reduction in mortality and morbidity over time.

Robotic colorectal surgery is a promising field and may provide a powerful additional tool for optimal management of more challenging pathology, including rectal cancer. Further studies are required to better define its role.

Aim:Robotic colorectal surgery is an emerging field and may offer a solution to some of the difficulties inherent to conventional laparoscopic surgery. The aim of this review is to provide a comprehensive and critical analysis of the available literature on the use of robotic technology in colorectal surgery. Methods:Studies reporting outcomes of robotic colorectal surgery were identified by systematic searches of electronic databases. Outcomes examined included operating time, length of stay, blood loss, complications, cost, oncological outcome, and conversion rates. Results:17 Studies (9 case series, 7 comparative studies, 1 randomised controlled trial) describing 288 procedures were identified and reviewed. Study heterogeneity precluded a meta-analysis of the data. Robotic procedures tend to take longer and cost more, but may reduce the length of stay, blood loss, and conversion rates. Complication profiles and short term oncological outcomes are similar to laparoscopic surgery. Conclusions:Robotic colorectal surgery is a promising field and may provide a powerful additional tool for optimal management of more challenging pathology, including rectal cancer. Further studies are required to better define its role.

Keeping the umbilical cord long and milking may be an effective method for improving Hb and iron stores at 6 months of age in term-infants.
