Meta Analysis
Prophylactic drainage after laparoscopic cholecystectomy for acute cholecystitis: a systematic review and meta-analysis.
In the literature, there is a large evidence against the use of drains in laparoscopic cholecystectomy (LC) in elective surgery. However, evidence is lacking in the setting of acute cholecystitis (AC). The present meta-analysis was performed to assess the role of drains to reduce complications and improve recovery in LC for AC. ⋯ No significant difference was present with respect to postoperative fluid collection in the subhepatic area and operative time. The present study shows that prophylactic drain placement is useless to reduce complications in LC performed to treat AC. Postoperative recovery is improved if drain is not present.

Review Meta Analysis
Local anaesthetic infiltration for the rubber band ligation of early symptomatic haemorrhoids: a systematic review and meta-analysis.
The objective of this article is to systematically analyse the randomized, controlled trials evaluating the effectiveness of local anaesthetic infiltration prior to the rubber band ligation of early symptomatic haemorrhoids. Published randomized, controlled trials comparing the use of local anaesthetic (LA) versus no-local anaesthetic (NLA) for the rubber band ligation of early symptomatic haemorrhoids were analysed using RevMan®, and the combined outcomes were expressed as odds ratios (OR) and standardized mean difference (SMD). ⋯ However, the post-procedure pain score (SMD -5.19; 95% CI -9.08, -1.30; z = 2.62; p < 0.009) was significantly lower in the group of patients undergoing rubber band ligation of haemorrhoids under local anaesthetic injection. The use of LA appears to have clinically measurable advantages over NLA in the rubber band ligation of early symptomatic haemorrhoids to lessen post-procedure pain.
