Description of intervention(s) / exposure
Not applicable - Observational study: in this study no experimental intervention or treatment is applied.It involves observations done in the retrospective manner.Data obtained from hospital database from yr Dec-2011-June-2012 Acute pain service data also used.Since the surgery has already been done there is no intervention in that course. But the satisfaction outcomes are measured by doing a likert score to observe what extent these methods benefited in each group.

Statistical methods / analysis
Group differences on continuous variables were assessed using the Wilcoxon (Mann-Whitney) test. Differences on dichotomous measures were assessed using Pearson’s Chi-square statistic or Fisher’s Exact test as appropriate. All tests were two-tailed and statistical significance was assessed at a 5% alpha level.

Summary
Brief summary
The key hole gall bladder surgery is one of the commonest surgery performed. there are various methods used for pain relief after the surgery.Traditionally local anaesthetics is injected into the wounds.Recently by ultrsound guidance local anaesthetics were injected into the abdonminal planes (transverses abdominis plane).The nerves supply the the entire abdominal wall. Recent trials did show they benefit in abdominal surgery. So far only one trial compared these two methods.The purpose of this trial is to find out which one of them did better in regards to pain releief. Also patient satisfaction score may reveal which of these methods were acceptable
