LC can be performed safely under epidural anaesthesia in patients with severe COPD. Intraoperative shoulder tip or abdominal pain does not seem to be a major deterrent and can be effectively controlled with small doses of opioid analgesia.

Gallbladder perforation should be reported according to the original Neimeier's classification to avoid heterogeneity in data (e.g. varying rates of perforation types). The algorithm proposed in this study aims to guide the management of complex type II gallbladder perforations to minimise subsequent morbidity and mortality.

In this study CRP on its own has been shown to have high predictive value in predicting GC, but larger studies are needed to validate this finding. Monitoring trend of CRP in patients with acute cholecystitis may help early diagnosis and decision for early surgical intervention.

BD stents provide good dysphagia relief for the life time of the stent. They may help avoid the use of feeding tubes in patients having radical chemoradiotherapy or awaiting oesophagectomy. They do not require removal or interfere with radiotherapy planning via imaging. However, the reintervention rate is high after the stent dissolves.
