Surgical approaches to chronic pancreatitis: indications and imaging findings

Chronic pancreatitis (CP) is an irreversible, inflammatory process characterized by progressive fibrosis of the pancreas that can result in abdominal pain, exocrine insufficiency, and diabetes. Inadequate pain relief using medical and/or endoscopic therapies is an indication for surgery. The surgical management of CP is centered around three main operations including pancreaticoduodenectomy (PD), duodenum-preserving pancreatic head resection (DPPHR) and drainage procedures, and total pancreatectomy with islet autotransplantation (TPIAT). PD is the method of choice when there is a high suspicion for malignancy. Combined drainage and resection procedures are associated with pain relief, higher quality of life, and superior short-term and long-term survival in comparison with the PD. TPIAT is a reemerging treatment that may be promising in subjects with intractable pain and impaired quality of life. Imaging examinations have an extensive role in pre-operative and post-operative evaluation of CP patients. Pre-operative advanced imaging examinations including CT and MRI can detect hallmarks of CP such as calcifications, pancreatic duct dilatation, chronic pseudocysts, focal pancreatic enlargement, and biliary ductal dilatation. Post-operative findings may include periportal hepatic edema, pneumobilia, perivascular cuffing and mild pancreatic duct dilation. Imaging can also be useful in the detection of post-operative complications including obstructions, anastomotic leaks, and vascular lesions. Imaging helps identify unique post-operative findings associated with TPIAT and may aid in predicting viability and function of the transplanted islet cells. In this review, we explore surgical indications as well as pre-operative and post-operative imaging findings associated with surgical options that are typically performed for CP patients.

Contemporary single-center surgical experiences in redo procedures of the pancreas: improved outcome and reduction of operative risk

INTRODUCTION

Redo procedures of the pancreas are complex operations associated with significant morbidity and mortality rates. The operative risk may be minimised when indications for redo procedure are well reflected and operation is performed by an experienced surgeon. The aim of this study was to confirm this hypothesis evaluating our experiences with redo procedures.

METHODS

We reviewed 28 patients (mean age of 54 years; range 11-75 years) undergoing a redo procedure of the pancreas from January 2004 to June 2008 at our hospital. The term redo procedure was defined as a pancreatic reoperation that was carried out after preceding pancreatic surgery. Relaparotomies following acute complications after pancreatic surgery were not taken into consideration.

RESULTS

The following parameters were evaluated: median operative time 332 min (range 160-730 min), median intraoperative blood loss 625 ml (range 300-2,800 ml), median postoperative stay on Intensive Care Unit 20 h (range 0-112 h), median postoperative hospital stay 15 days (range 7-98), morbidity (14%), and mortality (3.6%).

CONCLUSIONS

Redo procedures of the pancreas can be performed with low complication rates. In order to achieve a satisfactory outcome, the indication of redo procedures has to be well reflected, and operation may be performed by specialised and experienced surgeons.

Long-term follow-up after organ-preserving pancreatic head resection in patients with chronic pancreatitis

In chronic pancreatitis (CP), enlargement of the pancreatic head develops as a result of inflammatory alterations. This report relates to the results attained with an organ-preserving pancreatic head resection (OPPHR) in 135 patients in a 7-year period. The surgical procedure consists of a wide excision of the inflammatory tumor in the region of the pancreatic head, without division and cutting of the pancreas over the portal vein. Reconstruction, with drainage of the secretion from the remaining pancreas into the intestinal tract, takes place through a jejunal Roux-en-Y loop. Only one reoperation was required in consequence to anastomosis bleeding, but no mortality occurred in the postoperative period. The duration of hospitalization ranged between 7 and 12 days. The mean follow-up period was 4.1 years (range, 0.5-7.0). The late mortality rate was 3.7%. The quality of life, measured during the follow-up by using EORTC Quality-of-Life Questionnaire, improved in 89% of the patients. One hundred sixteen patients became complaint-free, while 14 patients had moderate symptoms; the weight increased by a median of 11.3 kg (range, 4-28). The 7-year experience clearly reveals that this OPPHR technique is a safe and effective procedure for definitive control of the complications of CP.

Prospective randomised comparison of organ-preserving pancreatic head resection with pylorus-preserving pancreaticoduodenectomy

BACKGROUND AND AIMS

In a prospective, randomised, control trial organ-preserving pancreatic head resection (OPPHR) was compared with pylorus-preserving pancreaticoduodenectomy (PPPD) to assess the advantages and disadvantages of each type of operation.

PATIENTS AND METHODS

Forty patients were allocated randomly to either the OPPHR (n=20) or the PPPD (n=20) group. The surgical data, postoperative complications, induction of diabetes mellitus, postoperative pain and quality of life 1 year, postoperatively, were considered.

RESULTS

The two study groups of 20 patients were well balanced with regard to sex, age, chronic pancreatitis history and indication for surgery. The duration of the operation for OPPHR and PPPD was 142.5+/-4.9 and 278+/-6.9 min, respectively (P<0.05). The postoperative mortality in each group was zero. After OPPHR and PPPD, the morbidity was 0 and 40%, respectively (P<0.05). The duration of hospital stay was also significantly different: 8.05+/-0.9 vs 13.8+/-3.9 days (P<0.05). After 1 year the pain relief was effective in both groups, but three patients acquired diabetes mellitus after PPPD; the body weight had increased by 7.8+/-0.9 and 3.2+/-0.3 kg after OPPHR and PPPD, respectively (P<0.05).

CONCLUSION

The two procedures are equally safe and effective with regard to pain relief, but OPPHR is superior to PPPD not only in the operation data and morbidity, but also in the quality of life 1 year postoperatively. OPPHR should be regarded as a recommended procedure in the treatment of chronic pancreatitis.
