The results of the economic evaluation suggest that , on average , the surgery strategy costs £ 1236 more per patient than the conservative management strategy but was , on average , more effective .
An increase in the number of people requiring surgery while treated conservatively corresponded to a reduction in the cost-effectiveness of the conservative strategy .
The results of this assessment indicate that cholecystectomy is still the treatment of choice for many symptomatic people .
However , approximately half of the people in the observation group did not require surgery or suffer complications in the long term indicating that a conservative therapeutic approach may represent a valid alternative to surgery in this group of people .
BACKGROUND Approximately 10 - 15 % of the adult population suffer from gallstone disease , cholelithiasis , with more women than men being affected .
Cholecystectomy is the treatment of choice for people who present with biliary pain or acute cholecystitis and evidence of gallstones .
However , some people do not experience a recurrence after an initial episode of biliary pain or cholecystitis .
As most of the current research focuses on the surgical management of the disease , less attention has been dedicated to the consequences of conservative management .
OBJECTIVES To determine the clinical effectiveness and cost-effectiveness of  cholecystectomy  compared with observation/conservative management in people presenting with uncomplicated symptomatic gallstones ( biliary pain ) or cholecystitis .
Wait-and-see policy or laparoscopic cholecystectomy after endoscopic sphincterotomy for bile-duct stones: a randomised trial
BACKGROUND Patients who undergo endoscopic sphincterotomy for common bile-duct stones , who have residual gallbladder stones , are referred for  laparoscopic cholecystectomy .  However , only 10 % of patients who do not have this operation are reported to develop recurrent biliary symptoms . We aim ed to assess whether a wait- and -see policy is justified . METHODS We did a prospect i ve , r and omised , multicentre trial in 120 patients ( age 18 - 80 years ) who underwent endoscopic sphincterotomy and stone extraction , with proven gallbladder stones . Patients were r and omly allocated to wait and see ( n=64 ) or laparoscopic cholecystectomy ( 56 ) . Primary outcome was recurrence of at least one biliary event during 2-year follow-up , and secondary outcomes were complications of cholecystectomy and quality of life . Analysis was by intention to treat . FINDINGS 12 patients were lost to follow-up immediately . Of 59 patients allocated to wait and see , 27 ( 47 % ) had recurrent biliary symptoms compared with one ( 2 % ) of 49 patients after laparoscopic cholecystectomy ( relative risk 22.42 , 95 % CI 3.16 - 159.14 , p<0.0001 ) . 22 ( 81 % ) of 27 patients underwent cholecystectomy , mainly for biliary pain ( n=13 ) or acute cholecystitis ( 7 ) . Conversion rate to open surgery was 55 % in patients allocated to wait and see who underwent cholecystectomy compared with 23 % in those who were allocated laparoscopic cholecystectomy ( p=0.0104 ) . Morbidity was 32 % versus 14 % ( p=0.1048 ) , and median hospital stay was 9 versus 7 days . Quality of life returned to normal within 3 months after either treatment policy . INTERPRETATION A wait- and -see policy after endoscopic sphincterotomy in combined cholecystodocholithiasis can not be recommended as st and ard treatment , since 47 % of expectantly managed patients developed at least one recurrent biliary event and 37 % needed cholecystectomy . No major biliary complications arose , but conversion rate was high
