Chirurgisches Vorgehen bei chronischer Pankreatitis

The major aims of surgical therapy in chronic pancreatitis (CP) are pain relief and good long-term quality of life with preservation of endocrine and exocrine organ function. The surgical approach is therefore focused on drainage of the congested pancreatic (and bile) duct as well as resection of fibrotic and calcified tissue. Draining procedures alone are adequate for drainage of pseudocysts (cystojejunostomy) and the pancreatic duct (Partington) if no inflammatory tumor is present in the organ. Most CP patients present with unclear head mass and subsequent duct dilation. In these patients the different modifications of duodenum-preserving pancreatic head resections (e.g. Beger, Bern) offer a preferable option. Partial duodenopancreatectomy is an alternative but may be difficult to perform due to inflammatory changes around the portal vein and venous collaterals. Segmental resection and V-shaped excision may be appropriate in special situations (segmental fibrosis, small duct disease) and are performed less frequently (approximately 5 %) in the entire surgical CP population. In cases of suspected CP-related malignancy, formal resections (partial, distal or total pancreaticoduodenectomy) must be the surgical procedures of choice and be performed according to oncological principles.     

Laterale Anastomosentechniken

Characteristic symptoms of chronic pancreatitis are difficult to manage conservatively. They include severe pain and endocrine and exocrine insufficiency. Surgical treatment with simple and extended draining procedures addresses pain relief and the management of chronic pancreatitis-associated complications of adjacent organs. Following the assumption that pancreatic duct changes with intraductal hypertension are the reason for pain, simple drainage procedures have reduced pain in up to 80% of patients, with low morbidity and mortality. In case of complications involving adjacent organs with inflammatory pancreatic head tumor and stenosis of the distal bile duct, extended drainage procedures with limited pancreatic head resection according to Frey and V-shaped excision of the ventral aspect of the pancreas have been performed successfully.     

Indications and outcomes of surgical management of chronic pancreatitis: literature review

Surgical management of chronic pancreatitis remains a challenge for surgeons. Last decades, the improvement of knowledge regarding to pathophysiology of chronic pancreatitis, improved results of major pancreatic resections, and new diagnostic techniques in clinical practice resulted in significant changes in the surgical approach of this condition. Intractable pain, suspicion of malignancy, and involvement of adjacent organs are the main indications for surgery, while the improvement of patient's quality of life is the main purpose of surgical treatment. The surgical approach to chronic pancreatitis should be individualized based on pancreatic anatomy, pain characteristics, exocrine and endocrine function, and medical co-morbidity. The surgical treatment approach usually involves pancreatic duct drainage procedures and resectional procedures including longitudinal pancreatojejunostomy, pancreatoduodenectomy, pylorus-preserving pancreatoduodenectomy, distal pancreatectomy, total pancreatectomy, duodenum-preserving pancreatic head resection (Beger's procedure), and local resection of the pancreatic head with longitudinal pancreatojejunostomy (Frey's procedure). Recently, non-pancreatic and endoscopic management of pain have also been described (splancnicectomy). Surgical procedures provide long-term pain relief, improve the patients? quality of life with preservation of endocrine and exocrine pancreatic function, and are associated with low mortality and morbidity rates. However, new studies are needed to determine which procedure is safe and effective for the surgical management of patients with chronic pancreatitis.

Abstract Objective To investigate the outcome after surgery directed by pathological anatomy of chronic pancreatitis and provide evidence for surgical procedures. Methods The clinical material of 60 patients with chronic pancreatitis who underwent surgical treatment between 2000 and 2010 were investigated retrospectively. Result 43 cases (71.7%) presented with abdominal pain, Perioperative mortality was 1.7% (1 case). Forty-two patients with abdominal pain were all relieved after surgery, but long-term recurrence occered in 17 cases (40.5%). Modified Puestow procedure was performed on 21 patients with dilatation of pancreatic duct and/or lithiasis, long-term pain recurrence occered in 8 cases (38.1%); Six patients undergoing pancreatic head resection had no recurrence in the long-term follow-up; Pain recurrence rate of 11 cases with only cholangioenterostomy was 81.2% (9 cases) within 2 years. Chronic pancreatitis with common bile duct obstruction occurred in 33 cases(55%), cholangioenterostomy alone or combined with partly pancreatic resection or pancreatic duct drainage procedures could alleviate symptoms of biliary obstruction, 4(33.3%) cases after pure biliary drainage emerged abdominal pain, 5 cases of pancreatic head resection had no recurrence of jaundice and abdominal pain after long-term follow-up. Conclusion Surgical procedures should be selected according to the pathological anatomy of chronic pancreatitis. Reasonable pancreatic head resection and adequate bile and/or pancreatic drainage could significantly improve the long-term outcomes.     

Local Resection of the Pancreatitic Head for Pancreatic Pseudocysts

Background  Local resection of the head (LRPH) has improved markedly the clinical outcome of patients that undergo surgery for chronic pancreatitis. LRPH is often combined with a lateral pancreatojejunostomy for complete duct drainage. Randomized controlled trials have confirmed the superiority of the Frey and Beger operations compared to pancreatoduodenectomy. Appropriate patient selection is critical to an excellent outcome. Patients with an enlarged pancreatic head or duodenal or biliary obstruction are ideal candidates for LRPH. In addition, patients with symptomatic pseudocysts in the pancreatic head can be adequately treated with these operations. Procedure  The procedure described herein includes a generous pancreatic head resection to ensure pain relief, a pancreatic ductotomy onto the body and tail of the gland for complete drainage, and an intrapancreatic biliary sphincteroplasty for decompression of an obstructed bile duct. Conclusions  Perioperative hemorrhage is a potential major complication associated with LRPH. The long-term outcome is an excellent pain relief and improves overall quality of life.     

Ductal drainage or resection for chronic pancreatitis

We report a 10 year review comparing the results of pain relief after three procedures for chronic pancreatitis: Whipple pancreatoduodenectomy, modified Puestow side-to-side longitudinal pancreaticojejunostomy and distal pancreatic resection. Results of follow-up review at 6 months, 2 years and 5 years were tabulated. Five year follow-up data were available on more than 80 percent of patients. The proportion of good results for pain relief decreased with the passage of time regardless of the procedure performed. Although equally good results are obtained after either pancreatoduodenectomy or pancreaticojejunostomy, we conclude that in the presence of a dilated duct, the procedure of choice is pancreaticojejunostomy. If the duct is not dilated, we then favor pancreatoduodenectomy, after which the pain relief is significantly better (p = 0.05) than after distal resection. Our data show that, for all factors evaluated, the poorest pain relief was obtained after distal resection. Therefore that procedure has limited value when used specifically for relief of pain in chronic pancreatitis, except in the uncommon circumstance when the disease is confined to the distal part of the gland. Our study also shows that patients who have more radical distal resection have no better pain relief than those who have 50 percent distal resection.     

What should be the standard operation in chronic pancreatitis: Whipple or duodenum-preserving pancreatic head resection?

Surgical options in the treatment of chronic pancreatitis have undergone both development and controversial discussion in the past decades. Operations such as the classical and pylorus-preserving Whipple resections are more and more being replaced by operations such as the duodenum-preserving pancreatic head resection, which preserves extrapancreatic organs like the stomach, the duodenum and the extrapancreatic bile duct. The latter operation preserves a normal food passage and glucose metabolism after surgical intervention. In addition, the duodenum-preserving pancreatic head resection provides long-term pain relief and reduction in up to 90% of chronic pancreatitis patients, as well as a general improvement in quality of life. This article will summarize and compare the surgical options in the treatment of chronic pancreatitis and will provide arguments why the duodenum-preserving pancreatic head resection should replace the classical and the pylorus-preserving Whipple resections as the standard surgical procedure used to treat chronic pancreatitis-related complications.     

Pancreatic duct pressure in chronic pancreatitis

The wide variety of surgical procedures available for the relief of pain in patients with chronic pancreatitis attests to a lack of understanding of the precise mechanisms responsible for the onset of pain in this condition. In the development of surgical procedures designed to “decompress” the pancreatic duct in chronic pancreatitis, it has been tacitly assumed that pancreatic duct hypertension exists and is important in the pathophysiology of the disease. In 19 patients with chronic pancreatitis and dilated pancreatic ducts, pancreatic duct pressure was significantly higher than in control patients. In view of the dramatic relief of preoperative pain after procedures for decompressing the pancreatic ducts, ductal hypertension has been confirmed as an important mechanism of pain production in this group of patients.     

Surgery for Chronic Pancreatitis

Chronic pancreatitis (CP) is progressive inflammatory process of the pancreas. Abdominal pain remains the most debilitating symptom affecting quality of life, apart from diabetes mellitus, steatorrhoea and weight loss. The treatment options have evolved over the past decades and are aimed to provide durable relief in pain with possible attempt to support or improve the failing endocrine and exocrine functions. Surgical treatment options have shown the potentials to provide superior long term results compared to the pharmacological and endoscopic modalities and are broadly divided in to drainage, resection and combination hybrid procedures. The choice is based on the morphology of the main pancreatic duct, presence of head mass and associated complication of CP. Knowing the basic nature of the disease, total pancreatectomy seems a curative option but not without significant morbidities. There is recent paradigm shift towards organ sparing surgical procedures with reasonable success. Despite recent advancement in the treatment modalities for CP the overall quality of life remains moderate which need further addressal.     

Surgical treatment of chronic pancreatitis

Debilitating abdominal or back pain remains the most common indication for surgery in patients with chronic pancreatitis. The surgical approach to chronic pancreatitis should be individualized based on pancreatic and ductal anatomy, pain characteristics, baseline exocrine and endocrine function, and medical co-morbidity. No single approach is ideal for all patients with chronic pancreatitis. Pancreatic ductal drainage with pancreaticojejunostomy targets patients with a dilated pancreatic duct and produces good early postoperative pain relief; however, 30%–50% of patients experience recurrent symptoms at 5 years. Resection for chronic pancreatitis should be considered (1) when the main pancreatic duct is not dilated, (2) when the pancreatic head is enlarged, (3) when there is suspicion of a malignancy, or (4) when previous pancreaticojejunostomy has failed. Re-sectional strategies include pancreaticoduodenectomy, distal pancreatectomy, total pancreatectomy, duodenum-preserving pancreatic head resection (Beger procedure), or local resection of the pancreatic head with longitudinal pancreaticojejunostomy (Frey procedure). Superior results are obtained when the pancreatic head is resected, either completely (pancreaticoduodenectomy) or partially (Beger or Frey procedure). Although pylorus-preserving pancreaticoduodenectomy remains the gold standard resection procedure, there is evidence that newer operations, such as the Beger resection, may be as effective in regard to pain relief and better in respect to nutritional repletion and preservation of endocrine and exocrine function.

Surgical treatment of pancreas divisum causing chronic pancreatitis: The outcome benefits of duodenum-preserving pancreatic head resection

Pancreas divisum (PD) represents a duct anomaly in the pancreatic head ducts, leading frequently leading to recurrent acute pancreatitis (rAP) or chronic pancreatitis (CP). Based on endoscopic retrograde cholangiopancreatography, pancreas divisum can be found in 1% to 6% of patients with pancreatitis. The correlation of this abnormality with pancreatic disease is an issue of continuing controversy. Because of the underlying duct anomalies and major pathomorphological changes in the pancreatic head, duodenumpreserving pancreatic head resection (DPPHR) offers an option for causal treatment. Thirty-six patients with pancreatitis caused by PD were treated surgically. Thirty patients suffered from CP, 6 from rAP. The mean duration of the disease was 47.5 and 49.8 months, respectively. The age at the time of surgery was 39.2 years in the CPgroup, and 27.6 years in the rAP group. Median hospitalization since diagnosis was 18.8 weeks for CP patients and 24.6 weeks for rAP patients. Previous procedures performed in these patients included endoscopic papillotomy (30%), duct stenting (14%), and surgical treatment (17%). The median preoperative pain score was 8 on a visual analog scale. According to the classification of pancreas divisum, 10 patients demonstrated a complete PD, 25 had a functionally incomplete PD, and 1 had a dorsal duct type. The pain status as well as the endocrine (oral glucose tolerance test) and exocrine (pancreolauryl test) function were evaluated preoperatively and early and late postoperatively with a median follow-up time of 39.3 months. There was no operative-related mortality. The follow-up was 100%; 4 patients died (1 from suicide, 1 from cardiac arrest, and 2 from cancer of the esophagus). Fifty percent of the patients were completely pain-free,31%hada significant reduction of pain with a median pain score of 2 (P < 0.001). Six patients (5 CP, 1 rAP) had further attacks of acute pancreatitis with a need for hospitalization. DPPHR reduced pain and preserved the endocrine function in the majority of patients with pancreas divisum. Therefore, DPPHR is an alternative to other resective or drainage procedures after failure of interventional treatment.     

Surgery and chronic pancreatitis

It is hoped that, in this millennium, chronic pancreatitis will be diagnosed earlier in the course of the disease process. Improved axial imaging of the pancreatic duct and pancreatic parenchyma will diminish the need for other invasive tests. Surgical procedures are directed at pancreatic duct decompression or resection of the pancreas (head, body or tail) or, infrequently, total pancreatectomy. Pain relief in 75% to 90% is the general rule, with diabetes developing subsequently in as many as 33% of patients. Surgery for chronic pancreatitis is effective in correcting sequelae of pancreatic fibrosis. Endoscopic stenting of the pancreatic and bile duct is used more frequently today. Until their place is ascertained, careful performance of surgery will continue to be a mainstay of treatment.     

Dorsal duct sphincterotomy is effective long-term treatment of acute pancreatitis associated with pancreas divisum

Nonbiliary, nonalcoholic pancreatic inflammatory disease was investigated by biochemical investigation, ultrasonography, endoscopic retrograde cholangiopancreatography, and secretin tests. Twenty-five consecutive cases were followed up for 12 months to 10 years after treatment of disease associated with pancreas divisum, diagnosed by endoscopic retrograde cholangiopancreatography. Thirteen patients had no recurrence of acute pancreatitis after dorsal duct sphincterotomy alone, during long-term follow-up (mean, 54 months); one patient had recurrent pancreatitis during 33 months after failed sphincterotomy. Eight patients had variable results 12 months to 8 years (mean, 49 months) after dorsal duct sphincterotomy for pancreatic pain syndrome (without amylase elevation), three were pain free, and one had recurrent pancreatitis. For 10 years after dorsal duct sphincterotomy for chronic pancreatitis, one patient had no pain relief; after subtotal pancreatectomy and pancreaticojejunostomy of the dorsal duct, both for chronic pancreatitis, one patient each was pain free and normoglycemic after 54 and 12 months, respectively. Dorsal duct sphincterotomy alone is successful in achieving long-term freedom from recurrence of acute pancreatitis associated with pancreas divisum. Pancreatic pain syndrome is not consistently improved by dorsal duct sphincterotomy. Chronic pancreatitis associated with pancreas divisum should be treated by resection or drainage procedures, not by dorsal duct sphincterotomy.     

Chronic pancreatitis. Results of Whipple's resection and total pancreatectomy

The aim of our study was to determine the success of radical pancreatic resection in relieving the pain of chronic pancreatitis. From 1974 to 1985, 30 consecutive patients underwent radical pancreatic resection for the treatment of debilitating pain (15 underwent Whipple's resection and 15 underwent total pancreatectomy). Patients were not randomized but were subjected to the procedure deemed indicated for their clinical presentation; thus, the two groups were not strictly comparable. There was no operative mortality; major morbidity occurred in three patients (20%) in each group (four patients experienced anastomotic bile leak and two experienced abdominal sepsis). Following Whipple's resection, mean follow-up was 6.2 years (range, 1.5 to 12.1 years). Complete pain relief occurred in eight patients (53%) and significant relief in an additional four (27%). Endocrine insufficiency developed in six patients and exocrine insufficiency in eight. Following total pancreatectomy, mean follow-up was 9.1 years (range, 2.1 to 13.1 years). Complete pain relief occurred in only four patients (27%) and significant relief in an additional six (40%). Significant pain persisted in about 33% of patients after total pancreatic resection. We concluded that radical pancreatic resection can be performed safely in patients with chronic pancreatitis but with gratifying results in only 67% to 80% of patients. Whipple's resection may be preferable for disease located primarily in the head of the gland.     

Surgical treatment of chronic pancreatitis and quality of life after operation.

In conclusion, surgical therapy in patients with chronic pancreatitis may be characterized as follows: 1. Independently, several investigators have found intraductal and intraparenchymatous hypertension in patients with chronic pancreatitis. Decompression of the ductal system as the main principle of surgical therapy achieves clinical pain relief in most patients with chronic pancreatitis. The precondition is a consequent drainage of the main pancreatic duct and tributary ducts of second and third order up to the prepapillary region. The presence of an inflammatory tumor in the head of the pancreas or ductal abnormalities in the prepapillary region or a pancreas divisum requires performance of an extended drainage operation (LPJ-LPHE) to achieve pain relief and an improved quality of life. An extended drainage operation effectively manages complications arising from adjacent organs, such as distal common bile duct stenosis, segmental duodenal stenosis, and internal pancreatic fistulas. The extent of decompression has to be tailored to the anatomic and morphologic situation of the patient. 2. In patients with chronic pancreatitis, the main pancreatic duct is usually dilated. A small duct (3-5 mm) is only small for the surgeon. For the sclerosing entity of chronic pancreatitis with a truly small duct, that is, less than 3 mm in diameter ("small duct disease"), a longitudinal V-shaped excision of the ventral pancreas, as opposed to left resection, provides a new perspective for a sufficient drainage. 3. In the presence of segmental portal hypertension, a simple or extended drainage operation does not result in a normalization of the portal venous blood flow; however, how often relevant upper gastrointestinal hemorrhage develops from segmental portal hypertension is unclear. Therefore, the clinical relevance of this special problem needs further evaluation. 4. Postoperative morbidity of LPJ-LPHE is significantly lower in comparison to resectional procedures, such as PD, PPPD, and DPRHP. A lower perioperative mortality rate is not justified anymore as a relevant criterion in favor of drainage procedures because resectional procedures are burdened by a minimal or no mortality in experienced centers; however, PD and PPPD are greatly hampered by a significantly decreased postoperative global quality of life as opposed to the LPJ-LPHE. This is reflected by a significantly lower rate of social and professional rehabilitation. 5. The incidence of exocrine and endocrine organ dysfunction is lower after LPJ-LPHE compared with PD or PPPD, but not compared with DPRHP. Preservation of the gastroduodenal passage and the continuity of the bile duct with its associated feedback mechanisms of exocrine pancreatic secretion and glucose metabolism seem to be responsible for this phenomenon. 6. An early surgical or endoscopic interventional drainage of the hypertensive pancreatic duct system possibly offers the chance to favorably manipulate the natural course of chronic pancreatitis with regard to a delayed onset of exocrine or endocrine insufficiency. 7. Late mortality reflects continued alcohol abuse rather than the effect of an operative procedure.     

Duodenum-preserving resection of the head of the pancreas

Summary. Duodenum-preserving resection of the head of the pancreas was developed 25 years ago by Beger. This procedure is indicated in patients suffering from chronic pain in combination with inflammation of the head of the pancreas, common bile duct obstruction, pancreatic duct obstruction and/or obstruction of the retropancreatic vessels. At the Inselspital in Berne, 74 patients underwent this operation between 1993 and 1996. The median length of the operation was 380 min, with the need for transfusion in a median of 0 units (0–6). There was no postoperative mortality. Total postoperative morbidity was 13 %. One patient needed relaparotomy on day 17 for small bowel obstruction. Median length of hospital stay was 11 days. Postoperatively, two patients developed diabetes. Duodenum-preserving resection of the head of the pancreas represents an organ-preserving principle of surgery. This procedure treats the complications of chronic pancreatitis and provides long-term pain relief in more than 80 % of patients.      

Evidence-based surgery in chronic pancreatitis

BACKGROUND: In the past two decades our knowledge of the pathophysiology and surgical treatment options in chronic pancreatitis has improved substantially. Surgical treatment in chronic pancreatitis has evolved from extending to organ-preserving procedures. DISCUSSION: The classical Whipple resection is no longer a standard procedure in chronic pancreatitis, and is continuously being replaced by operations such as the duodenum-preserving pancreatic head resection and pylorus-preserving Whipple. These procedures allow the preservation of exocrine and endocrine pancreatic function, provides pain relief in up to 90% of patients, and contributes to an improvement in life quality. CONCLUSIONS: In addition to presently available results from randomized controlled trials, new studies comparing available surgical approaches in chronic pancreatitis are needed to determine which procedure is the most effective in the treating chronic pancreatitis.     

Chronic pancreatitis: A surgical disease? Role of the Frey procedure

Although medical treatment and endoscopic interven-tions are primarily offered to patients with chronic pancreatitis, approximately 40% to 75% will ultimately require surgery during the course of their disease. Al-though pancreaticoduodenectomy has been considered the standard surgical procedure because of its favorable results on pain control, its high postoperative complica-tion and pancreatic exocrine or/and endocrine dysfunc-tion rates have led to a growing enthusiasm for duodenal preserving pancreatic head resection. The aim of this review is to better understand the rationale underlying of the Frey procedure in chronic pancreatitis and to ana-lyze its outcome. Because of its hybrid nature, combin-ing both resection and drainage, the Frey procedure has been conceptualized based on the pathophysiology of chronic pancreatitis. The short and long-term outcome, especially pain relief and quality of life, are better after the Frey procedure than after any other surgical proce-dure performed for chronic pancreatitis.     

Longitudinal V-shaped excision of the ventral pancreas for small duct disease in severe chronic pancreatitis: prospective evaluation of a new surgical procedure.

OBJECTIVE: The technique of longitudinal V-shaped excision of the ventral pancreas for small duct chronic pancreatitis is presented and its efficacy in terms of pain relief and improvement of quality of life is evaluated. SUMMARY BACKGROUND DATA: Small duct chronic pancreatitis has been regarded as a classical indication for more or less extensive resection, in which the therapeutic success of pain relief is offset by the considerable risk of significant perioperative mortality and morbidity and the burden of substantial loss of pancreatic function. METHODS: Thirteen patients with severe pain who were diagnosed with small duct pancreatitis (defined as maximal Wirsungian ductal diameter of 2 mm) underwent longitudinal V-shaped excision of the ventral pancreas. In addition to routine pancreatic workup, a multidimensional psychometric quality-of-life questionnaire and a pain score were used. Assessment of exocrine and endocrine function included fecal chymotrypsin and the pancreolauryl test as well as oral glucose tolerance, serum concentrations of insulin, C-peptide, and hemoglobin A1c. The interval between symptoms and surgery ranged from 12 months to 10 years (mean, 5.4 years). Median follow-up was 30 months (range, 12-48 months). RESULTS: There were no deaths. Overall morbidity was 15.4%. In 92% of patients, complete relief of symptoms was obtained. Median pain score decreased by 95%. Physical status, working ability, and emotional and social functioning scores improved by 40%, 50%, 67%,, and 75%, respectively. Global quality-of-life index increased by 67%. Occupational rehabilitation was achieved in 69% of patients. Exocrine and endocrine pancreatic function was well preserved. CONCLUSIONS: In small duct chronic pancreatitis, longitudinal V-shaped excision of the ventral pancreas is a safe and effective alternative to resection procedures. The new technique provides pain relief and improvement of quality of life, thus offering the benefit of a resection procedure without its burden.
