Although benign in itself, hepatocellular adenoma (HCA) can be complicated by hormone-induced growth, and subsequent haemorrhage and rupture. The exact risk of haemorrhage and rupture is not known. This systematic review of the literature was carried out with the aim of estimating the risk of haemorrhage and rupture in HCA. ⋯ Haemorrhage and rupture are common in patients with HCA.

Randomized Controlled Trial
Pancolonic motor response to subsensory and suprasensory sacral nerve stimulation in patients with slow-transit constipation.
Sacral nerve stimulation (SNS) is emerging as a potential treatment for patients with constipation. Although SNS can elicit an increase in colonic propagating sequences (PSs), the optimal stimulus parameters for this response remain unknown. This study evaluated the colonic motor response to subsensory and suprasensory SNS in patients with slow-transit constipation. ⋯ In patients with slow-transit constipation, suprasensory SNS increased the frequency of colonic PSs, whereas subsensory SNS stimulation did not. This has implications for the design of therapeutic trials and the clinical application of the device.

Outcomes after oesophagectomy and gastrectomy vary considerably between hospitals. Possible explanations include differences in case mix, hospital volume and hospital type. The present study examined the distribution of oesophagectomies and gastrectomies between hospital types in the Netherlands, and the relationship between hospital type and outcome. ⋯ Oesophagogastric resections performed in UH were associated with better outcomes but, owing to variation in outcomes within hospital types, centres of excellence cannot be designated solely on hospital type. Detailed information on case mix and outcomes is needed to identify centres of excellence.

Endovascular repair of ruptured abdominal aortic aneurysm (rAAA) has rapidly gained popularity, but superior results may be biased by patient selection. The aim was to investigate whether suitability for endovascular repair predicted survival, irrespective of technique of repair. ⋯ Endovascular suitability was an independent and strongly positive predictor of survival after open repair of rAAA.

Comparative Study
Selective hepatic vascular exclusion versus Pringle manoeuvre in liver resection for tumours encroaching on major hepatic veins.
Control of bleeding is crucial during liver resection, and several techniques have been developed to achieve this. This study compared the safety and efficacy of selective hepatic vascular exclusion (SHVE) and Pringle manoeuvre in partial hepatectomy for liver tumours compressing or involving major hepatic veins. ⋯ SHVE was more efficacious than the Pringle manoeuvre in minimizing intraoperative bleeding and air embolism during partial hepatectomy for tumours encroaching on major hepatic veins, and decreased the postoperative liver failure rate.
