TRIAL DESCRIPTION
Public title Necrotizing biliary pancreatitis: time for cholecystectomy
Official scientific title Necrotizing biliary pancreatitis: time for cholecystectomy randomised controlled trial (NBPTC)
Brief summary describing the background and objectives of the trial Acute necrotizing or necrotic-hemorrhagic pancreatitis accounts for 10-25% of all forms of acute pancreatitis, with High mortality and morbidity due to Multi-visceral failure syndrome and Superinfection of necrosis. Biliary origin most frequent in TUNISIA Time for cholecystectomy is a controversial subject, There is No consensus with a high level of evidence We classically wait the ad integrum restitution of flows (about 3 months) to do the cholecystectomy, but in this time many patients develop recurrent pancreatitis, which is usually more severe before undergoing cholecystectomy. We propose to conduct a randomised, single-blind, unilateral controlled trial to assess the safety of early cholecystectomy in acute necrotising pancreatitis compared with late cholecystectomy. o Treatment tested (Group A): early cholecystectomy o Control group (Group B): delayed cholecystectomy  Early cholecystectomy = during the same hospitalisation (within 15 days of symptomatology).  Delayed cholecystectomy = after restitution ad integrum of the necrosis flows. Our Primary endpoint: perioperative complications (hemorrhage, biliary wound and superinfection of necrosis flows)

STUDY DESIGN
Intervention assignment Allocation to intervention If randomised, describe how the allocation sequence was generated Describe how the allocation sequence/code was concealed from the person allocating the participants to the intervention arms Masking If masking / blinding was used
Factorial: participants randomly allocated to either no, one, some or all interventions simultaneously Randomised Simple randomization using a randomization table created by a computer software program Allocation was determined by the holder of the sequence who is situated off site Masking/blinding used Care giver/Provider
INTERVENTIONS
Intervention type Intervention name Dose Duration Intervention description Group size Nature of control
Experimental Group Early Cholecystectomy within 15 days of the onset of symptoms We will practice an Early laparoscopic cholecystectomy during the same hospital stay of the acute necrotizing panceatitis (within 15 days of the onset of symptoms). 46
Control Group Delayed Cholecystectomy after 15 days at least from beginig of symptoms We will practice a delayed laparoscopic cholecytectomy after that the necrosis flows have been restored ad integrum. 46 Active-Treatment of Control Group
