Review Meta Analysis
Systematic review and meta-analysis of continuous local anaesthetic wound infiltration versus epidural analgesia for postoperative pain following abdominal surgery.
Local anaesthetic wound infiltration techniques reduce opiate requirements and pain scores. Wound catheters have been introduced to increase the duration of action of local anaesthetic by continuous infusion. The aim was to compare these infiltration techniques with the current standard of epidural analgesia. ⋯ Within a heterogeneous group of RCTs, use of local anaesthetic wound infiltration was associated with pain scores comparable to those obtained with epidural analgesia. Further procedure-specific RCTs including broader measures of recovery are recommended to compare the overall efficacy of epidural and wound infiltration analgesic techniques.

The treatment of papillary thyroid carcinomas larger than 1 cm usually consists of total thyroidectomy and central lymph node dissection (LND). In patients with the follicular variant of papillary thyroid carcinoma (FVPTC), preoperative cytology and intraoperative frozen-section analysis cannot always establish the diagnosis. The aim of this study was to evaluate predictive factors for lymph node metastasis in patients with FVPTC and to identify patients who might benefit from LND. ⋯ The rate of lymph node metastasis in patients with FVPTC varies widely according to the presence or absence of predictive risk factors.

The aim was to assess the risk of rupture, and determine the benefits of intervention for the treatment of type II endoleak after endovascular abdominal aortic aneurysm repair (EVAR). ⋯ Aortic aneurysm rupture after EVAR secondary to an isolated type II endoleak is rare (less than 1 per cent), but over a third occur in the absence of sac expansion. Translumbar embolization had a higher success rate with a lower risk of complications.

Recent studies in the USA have shown a lower postoperative mortality rate in mildly obese patients, described as the 'obesity paradox'. The results from the relatively obese population in Western countries may not be generalizable to Asian countries, prompting the present study to investigate the relationship between body mass index (BMI) and outcomes after gastrointestinal surgery. ⋯ Unlike previous studies in the USA, in the present national Japanese cohort of patients undergoing surgery for gastrointestinal cancer, those who were either underweight or overweight had more postoperative complications and greater perioperative costs than those of normal weight.
