– Timing of surgery• Non-surgical management as long as possible to avoid
surgical complications
• Better pain relief with early surgical drainage
• Decision regarding timing of surgery be individualized on a patient to patient basis.
• With failure of medical management, counsel regarding the risks and benefits of both modalities.

» Known as “Hamburg modification”
» Inflammatory head mass + Small duct disease
» More extensive excavation of head + lateral decompressive pancreaticojejunostomy of the body and tail
www.nidhihospital.org
![Page 16: Surgical Management of Chronic Pancreatitis](https://reader035.fdocuments.in/reader035/viewer/2022062304/55d1b0c8bb61eb36288b46f3/html5/thumbnails/16.jpg)
• Drainage procedures– Indication• Isolated dilatation of the pancreatic duct >7mm or
“chain of lakes” appearance without an inflammatory mass in the head
• Generalized parenchymal involvement (no focal involvement)
• Recurrent or progressive segmental stenosis of the pancreatic duct
www.nidhihospital.org
![Page 17: Surgical Management of Chronic Pancreatitis](https://reader035.fdocuments.in/reader035/viewer/2022062304/55d1b0c8bb61eb36288b46f3/html5/thumbnails/17.jpg)
– Procedures• Duval’s procedure (1954)
– Drainage of the tail with a Roux-en-Y limb of jejunum
– Not effective for disease in the proximal pancreas
www.nidhihospital.org
![Page 18: Surgical Management of Chronic Pancreatitis](https://reader035.fdocuments.in/reader035/viewer/2022062304/55d1b0c8bb61eb36288b46f3/html5/thumbnails/18.jpg)
• Puestow’s procedure (Lateral P-J) (1958)– Longitudinal decompression of the body and tail of the
pancreas into a Roux limb of jejunum
– Initially described in conjunction with splenectomy and the distal pancreatectomy
www.nidhihospital.org
![Page 19: Surgical Management of Chronic Pancreatitis](https://reader035.fdocuments.in/reader035/viewer/2022062304/55d1b0c8bb61eb36288b46f3/html5/thumbnails/19.jpg)
• Partington’s lateral P-J (1960)– P-J without resection of the pancreatic tail
– Maximum pancreatic tissue preservation
– Recurrence of symptoms on long term due to incomplete decompression of MPD in head
www.nidhihospital.org

• Resection procedures– Indications• Focal disease, confined to head of pancreas (except in
distal pancreatectomy)
• Suspicious malignant lesion
• Obstructive complication developed by fibrosis
• Non dilated duct
– Disadvantages• Endocrine insufficiency
• Exocrine insufficiencywww.nidhihospital.org

![Page 23: Surgical Management of Chronic Pancreatitis](https://reader035.fdocuments.in/reader035/viewer/2022062304/55d1b0c8bb61eb36288b46f3/html5/thumbnails/23.jpg)
• Traverso’s pylorus preserving pancreaticoduodenectomy– Preservation of pylorus
– Improved QOL compare to Whipples’ pancreaticoduodenectomy
www.nidhihospital.org
![Page 24: Surgical Management of Chronic Pancreatitis](https://reader035.fdocuments.in/reader035/viewer/2022062304/55d1b0c8bb61eb36288b46f3/html5/thumbnails/24.jpg)
• Distal pancreatectomy– Isolated involvement of body and tail
– With or without splenectomy
– Stump closure by sutures or stapler application or by creating a Roux-en-Y pancreatojejunostomy
– Post-operative outcome is similar in both groups
– Drainage procedure should be reserved for patients with a dilated duct and/or a stricture in the pancreatic head
www.nidhihospital.org
![Page 25: Surgical Management of Chronic Pancreatitis](https://reader035.fdocuments.in/reader035/viewer/2022062304/55d1b0c8bb61eb36288b46f3/html5/thumbnails/25.jpg)
– Major portion of parenchyma remains untreated
– High risk of recurrence
– Requirement of completion pancreatectomy in 13%

![Page 26: Surgical Management of Chronic Pancreatitis](https://reader035.fdocuments.in/reader035/viewer/2022062304/55d1b0c8bb61eb36288b46f3/html5/thumbnails/26.jpg)
• Total pancreatectomy– For persistence or recurrent pain
– Extended hospitalisation due to poor diabetes control
– Profound metabolic consequences in absence of islet transplantation
– Outcomes identicles with Whipple’s pancreaticoduodenectomy
www.nidhihospital.org

• Beger’s duodenum preserving pancreatic head resection– Division of the neck overlying the confluence of the
splenic and superior mesenteric veins + Removal of the head of the pancreas, leaving a small rim of pancreatic tissue along the duodenum
– Maintain GI and biliary continuity
– Better long term outcomes
www.nidhihospital.org
![Page 28: Surgical Management of Chronic Pancreatitis](https://reader035.fdocuments.in/reader035/viewer/2022062304/55d1b0c8bb61eb36288b46f3/html5/thumbnails/28.jpg)
• Bern Modification of DPPHR– Pancreas is not divided at level of portal vein
– Useful in significant inflammation and PHTN
– Less intra-operative bleeding– Equal outcome compare to Beger’s procedure
www.nidhihospital.org
![Page 29: Surgical Management of Chronic Pancreatitis](https://reader035.fdocuments.in/reader035/viewer/2022062304/55d1b0c8bb61eb36288b46f3/html5/thumbnails/29.jpg)
• Comparison of results (PD vs Beger’s vs Frey)– Study of 43 patients by Klempa et al• DPPHR patients had a shorter hospital stay, greater
weight gain, less post operative diabetes, and exocrine dysfunction than standard Whipple patients
• Pain control was similar between two groupsKlempa I, Spatny M, Menzel J, et al. Chirurg.1995;66:350 –359

– Study of 40 patients by Buchler et al• DPPHR patients had better pain relief, glucose
tolerance, and weight gain compared with PPPD patients
Buchler MW, Friess H, Muller MW, et al. Am J Surg. 1995;169:65– 69; discussion 69 –70
– LR-LPJ and DPPHR compared with the PPPD• Shorter operation times
• Less intraoperative blood loss
• Less perioperative transfusion requirementsAspelund G, Topazian MD, Lee JH, et al.J Gastrointest Surg. 2005;9: 400 – 409

– Study by Farkas et al examined 40 patients• Randomized to PPPD or organ-preserving pancreatic
head resection (OPPHR)
• OPPHR was associated with a shorter operating time, less post operative morbidity, shorter hospital stay, and better quality of life than PPPD.
• The degree of pain relief was equalFarkas G, Leindler L, Daroczi M, et al. Langenbecks Arch Surg. 2006;391:338 –342

• Conclusion– Pain relief and quality of life - main concern in
treatment of chronic pancreatitis
– Surgery is indicated for relief of intractable pain and complications associated with CP
– Timing of surgery should be individualized on a patient to patient basis.
