: Chronic pancreatitis has been defined as a continuing inflammatory disease of the pancreas characterized by irreversible morphological changes. These changes typically cause pain and loss of exocrine and endocrine pancreatic function. The most common symptom of chronic pancreatitis is pain, which can be severe and intractable in some patients. Although it is itself benign, chronic pancreatitis can significantly affect quality of life and can cause significant distress with its complications 
. The initial treatment for pain in most cases is to start of enzyme replacement, control of diabetes with insulin, and administration of oral analgesics. Surgical intervention is required in patients with intractable pain that is resistant to conventional nonsurgical therapy, in patients with associated or suspected malignancy, and in patients who have developed complications such as biliary or duodenal obstruction, pancreatic fistulae, pancreatic ascites/pleural effusion, pseudocyst, or rare hemosuccus pancreaticus 
. The aetiology of pain in chronic pancreatitis is unclear. Some evidence has suggested that perineural inflammation may be the cause of pain. A dilated pancreatic duct, secondary to obstruction, may cause increased intraductal pressures, resulting in pain 
. The primary aim of therapy is the achievement of primary pain relief and an improvement in quality of life. This could be achieved by means of endoscopic, open or laparoscopic /robotic lateral pancreaticojejunostomy [4, 13]
Methods: We selected 41 cases of chronic pancreatitis of both genders with moderate to intractable pain hampering routine life. All patients tried conservative treatment for more than 6 months. All selected patients underwent haematological and radiological work up. MRCP of all patients showing dilated pancreatic duct more than 7mm. in size. All of these patients operated for longitudinal pancreaticojejunostomy (Modified Puestow’s). Follow up done for one year to ten years
Results: All 41 patients in long term follow up were recovered well from pain and abdominal discomfort. Appetite were improved and weight gain noted in the patients after surgery.
Conclusions: Longitudinal pancreaticojejunostomy is still safe, simple and timely approved procedure for pain associated with chronic pancreatitis.
