Reduction in right upper quadrant pain after laparoscopic cholecystectomy together with lack of any difference in prevalence of mild gastrointestinal symptoms (such as indigestion and heartburn) between two groups suggest that factors associated with operative procedures may be responsible at least in part for the difference in symptoms in the both groups [18]. Stiff et al. reported that significantly fewer patients complained of right upper quadrant pain after laparoscopic cholecystectomy than after conventional surgery (3% v/s 10% P<0.05) and postulated that intercostal nerve. might be damaged by subcostal wound which may lead to neuroma formation. Other potential explanations include a reduction in intra-operational adhesions or the placebo effect of surgery [18]. According to Peterli et al. [15] the aetiologies of the postcholecystectomy syndrome after laparoscopic cholecystectomy were: residual stones (1%), subhepatic fluid formation (0.8%), incisional hernia (0.4%), peptic disease (4%), wound pain (2.4%) and functional disorders (26%). Schoenemann et al. [19] found that functional disorders were the most common cause of PCSs. In this study, flatulent dyspepsia persisted in 23.7% cases who had a complained of flatulent dyspepsia before operation and 8.0% cases who had no complaint of flatulence before operation. Flatulent dyspepsia was most common symptom after cholecystectomy in both groups. Bates et al. [20] found that commonest persisting symptoms, 12 months after cholecystectomy was excessive flatulence (47%), indigestion (46%). Scar related problems are more common in open group as compared to lap group [7,21]. In Stiff et al. [18] study found 1.3% incidence of incisional hernia after open cholecystectomy as compared to 0% after laparoscopic cholecystectomy. Port site abscess formation due to a dropped non-opaque gallstone is an unusual complication of laparoscopic cholecystectomy in which diagnosis was suggested with combination of ultrasound and computed tomography findings and confirmed by surgery [22]. One case of port site parietal abscess was present after lap cholecystectomy in this study which was diagnosed by CT scan but no calculus or foreign body was found in abscess cavity
