Overview

Surgery is usually considered when pain management fails with medical and endoscopic therapies. The goals of surgery include effective pain relief, and to preserve long-term pancreatic function. Surgery for chronic pancreatitis tends to be divided into two areas - resectional and drainage procedures. Dilated pancreatic duct may be managed with lateral pancreaticojejunostomy (LPJ) and lateralpancreaticojejunostomy with localized pancreatic head resection. Nondilated pancreatic duct is usually managed with pancreaticoduodenectomy, duodenal-preserving pancreatic head resection (DPPHR), distal pancreatectomy (DP) and total pancreatectomy (TP).

Surgery for the pain management:

1. Dilated pancreatic duct:

1.1 Lateral pancreaticojejunostomy (LPJ):

  • LPJ is the conventional surgical approach for pancreatic drainage.[4][5]
  • The procedure involves connecting the pancreatic duct to a Roux-en-Y jejunal limb for drainage.
  • Laparoscopic LPJ is the minimally invasive procedure with the success rate being directly proportional to the duct size.[6][7]
  • Complications such as intraoperative hemorrhage, postoperative hemorrhage and anastomotic leak are less common with this procedure.[5][8]

1.2  Lateral pancreaticojejunostomy with localized pancreatic head resection:

2. Nondilated pancreatic duct:

2.1 Head-dominant disease :
  • Common techniques for pancreatic head resection include:
  • Multiple trials have failed to prove any significant advantage of one technique over the other.[12][13][14][15][16][17]
  • The operative time and the length of stay after DPPHR was found to be shorter in trials.
2.1.1 Pancreaticoduodenectomy
  • Classic pancreaticoduodenectomy may cause significant pain relief in patients with chronic pancreatitis.[18][19][20][21]
  • PPPD is based on the idea of intact gastric emptying mechanism.[22]
  • PPPD is being used as a standard technique in modern pancreatic surgery but the nutritional advantages still need to be established.[23][24][25][26][27]
  • When compared with classic PD, retrospective studies on PPPD have shown:
    • Earlier return-to-work[24]
    • Better quality of life[26]
  • Laparoscopic PD and Robot-assisted laparoscopic PD are found to have the following favorable outcomes when compared to open PD.[28][29][30][31][32]
    • Reasonable operative time (357 to 368 minutes)
    • Minimal blood loss(75 to 240 cc)
    • Decreased morbidity (26.7 to 42 percent)
    • Lower pancreatic fistula rates (6.7 to 18 percent)
2.1.2 Duodenal-preserving pancreatic head resection (DPPHR):
  • In 1980, Beger described duodenal-preserving pancreatic head resection (DPPHR) technique for chronic pancreatitis to decrease the morbidity of pancreatic head resection.[33][13][27][33][34][35]

2.2 Tail-dominant disease

2.3 Diffuse parenchymal disease:

  • Total pancreatectomy (TP) may be helpful for pain relief in patients with chronic pancreatitis with diffuse pancreatic involvement.
  • Total pancreatectomy (TP) includes:
  • Total pancreatectomy (TP) is effective in following cases:
    • Patients with diffuse small duct pancreatitis
    • Patients with genetic pancreatitis
    • Patients who have failed previous pancreatic surgeries of a lesser extent (salvage pancreatectomy)
  • Total pancreatectomy (TP) may result in brittle type 3c pancreatogenic diabetes.[43][44]
  • Total pancreatectomy with islet autotransplantation (TPIAT) is being used more commonly to decrease the morbidity resulting from total pancreatectomy (TP).[45][46]
