Laparoscopic liver surgery is becoming more popular, and many high-volume liver centers are now gaining expertise in this area. Laparoscopic left lateral hepatectomy (LLLH) is a standardized and anatomically well-defined resection and may transform into a primarily laparoscopic procedure for cancer surgery or living donor hepatectomy for transplantation. Five case-control series were identified comparing a total of 167 cases (86 cases of LLLH plus 81 cases of open left lateral hepatectomy). Groups were matched by age and sex, with broadly similar indications for surgery and resection techniques. LLLH is associated with shorter hospital stays and less blood loss without compromising the margin status or increasing complication rates. Donors of LLLH grafts did not have higher graft-related morbidity. Prospective studies are required to define the safety in terms of disease-free and overall survival in this new avenue in laparoscopic liver surgery.

Concerns about the over-prescription of peri-operative fluids, particularly normal saline, culminated in the recent publication of UK national guidelines on fluid prescription during and after surgery. A working group comprising members of the nutrition support team, surgeons, anaesthetists and pharmacists therefore sought to reduce the overall levels of fluid prescription and to limit normal saline usage in our large Teaching Hospital by producing written local fluid prescribing guidelines and holding a series of fluid prescription education sessions for consultants and junior staff. Ideally, the success of such measures would have been determined by studies on fluid balance, body weight and/or measured body water in large numbers of individual patients in a large cluster-randomised controlled trial. However, this would have proved logistically difficult and very costly especially as it is notoriously difficult to rely on the accuracy of daily fluid balance charts in large numbers of patients on busy post-operative surgical wards. We therefore undertook a pragmatic study, comparing historical data on fluid type/volume prescribed (from both individual and ward level pharmacy records), The UK Reference Nutrient Intake for sodium (Na) suitable for maintenance in normal adults is 70 mmol/24 h, which should be accompanied by about 1 . 5-2 . 5 litres Abbreviations: IV, intravenous; MEWS, medical early warning score; OD, oedematous.
