Has the Partington procedure for chronic pancreatitis become a thing of the past? A review of the evidence

Endoscopic ultrasound-guided versus surgical pancreatic duct drainage after failed endoscopic retrograde pancreatography: a pilot comparative study

BACKGROUND

Endoscopic ultrasound-guided pancreatic duct (PD) drainage (EUS-PDD) is being increasingly performed as an alternative method to surgical drainage to achieve PD decompression after failed endoscopic retrograde pancreatography (ERP). However, no directly study has compared EUS-PDD with surgical PD drainage after failed ERP in patients with chronic pancreatitis.

METHODS

Consecutive patients who underwent EUS-PDD or longitudinal pancreaticojejunostomy after failed ERP were retrospectively identified from our endoscopy and medical information systems. The primary end point was the Izbicki pain score. The secondary end points were pain relief at the end of follow-up, procedure outcomes, adverse events, readmission, and reintervention.

RESULTS

A total of 21 patients (11 EUS-PDD, 10 surgical drainages) were analyzed. There were no significant differences in mean Izbicki pain score (EUS-PDD, 13.6 ± 10.1 vs. surgical drainage 10.7 ± 7.9, p = 0.483) or complete/partial pain relief (60%/30% vs. 70%/30%, p = 0.752) at the end of follow-up of the two groups. The rates of overall adverse events (27.3% vs. 30.0%, p = 0.893) and readmission (63.6% vs. 40.0%, p = 0.290) were similar in the two treatment groups, while patients in EUS-PDD group required more reinterventions (45.5% vs. 0%, p = 0.039) compared with patients in the surgery group.

CONCLUSION

EUS-PDD showed comparable pain relief and safety to surgical PD drainage after failed ERP, with a higher rate of reintervention. The selection of EUS-PDD or surgical drainage may be appropriate based on an individualized strategy.

Surgical Treatment for Chronic Pancreatitis With a Normal-Sized Pancreatic Head and a Dilated Duct: Frey or Extended Partington Procedure?

BACKGROUND

Surgical drainage for chronic pancreatitis patients with a normal-sized pancreatic head remains controversial. Both Frey and extended Partington procedures could be used, but the level of evidence is weak.

METHOD

The object of this prospective cohort study was to assess the mid-term results concerning pain, quality of life, and pancreatic function of surgical drainage (Frey or extended Partington procedure) in patients with painful chronic pancreatitis and a normal-sized pancreatic head.

RESULTS

Fifty-nine patients (Frey procedure: 14 cases; extended Partington procedure: 45 cases) were enrolled in the study with a median length of follow-up of 16 months. The effective and complete pain relief rate was 85% and 58%, respectively. The Izbicki score decreased from 53.4 preoperatively to 8.8 postoperatively. The general 12-Item Short Form Health Survey (SF-12) score increased from 45.2 to 75.4. The pancreatic insufficiency did not change significantly postoperatively. At three months after surgery, the complete pain relief and Izbicki score were more favorable in the Frey group than in the extended Partington group.

CONCLUSION

Both Frey and extended Partington procedures resulted in excellent pain relief and quality of life improvement and did not worsen pancreatic function. The Frey procedure could yield a more favorable result in the early postoperative period.

Surgical strategies for chronic pancreatitis in a 1,327- patient Scandinavian Baltic pancreatic Club (SBPC) register

BACKGROUND

Chronic pancreatitis (CP) may cause intermittent or continuous pain and complications requiring invasive interventions. No specific recommendations for surgical interventions have been presented. Our aim was to determine the surgical treatment strategies for the treatment of CP in the Scandinavian and Baltic countries.

METHODS

This multi-centre cross sectional study included 1327 CP patients from eight centres. The data was gathered from the Scandinavian Baltic Pancreatic Club (SBPC) database. Patients who underwent pancreatic surgery were analysed. The baseline CP population from the eight centres was used as a reference. The information registered included comorbidities, pancreatic function, previous interventions, time and type of surgery and the EORTC-30 quality of life (QOL) questionnaire.

RESULTS

Overall, 95/1327 (7%) patients underwent pancreatic surgery. Fifty-one (54%) of these underwent pancreatic surgery for chronic pain (PSCP) and formed the final study group. Median follow-up time was two (range 0-8) years after surgery and seven (1-46) years after diagnosis. The most common surgical procedures were pancreatic resection combined with drainage (54%) followed by pancreatic resections (32%) and drainage procedures (14%). Postoperatively, 47% of the patients were pain free with or without pain medication while 16% had chronic pain episodes, this did not differ from the base CP population. In QOL questionnaires, PSCP patients reported the same QOL but worse social functioning and more symptoms compared to the CP population.

CONCLUSIONS

Pancreatic surgery for CP is rare: surgical procedures were performed on only 7% of the CP patients in the SBPC database. In half of the patients the indication was pain. Most of these patients underwent endoscopic procedures before surgery. Half of the patients reported being pain-free after surgery.

Re-pancreaticojejunostomy for Necrosis of the Roux-en-Y Limb Tip 14 Years After Partington-Rochelle Procedure

Longitudinal pancreaticojejunostomy for chronic pancreatitis, the Partington-Rochelle (PR) procedure, is a good option to control pain caused by dilation of the main pancreatic duct. However, long-term complications related to anastomosis are still unclear. Here, we present a case of a 78-year-old patient with sudden necrosis of the Roux-en-Y limb tip in a PR procedure performed 14 years ago. During emergent laparotomy, we resected the necrotic limb and re-anastomosed the remaining Roux-en-Y limb to the main pancreatic duct. Postoperatively, we managed the inflammation caused by the pancreatic fistula and successfully saved the patient by long-term drainage. Although the cause of necrosis is still unclear, mild kinking and stenosis of the Roux-en-Y limb might be associated with this situation.

Pancreatitis After Pancreaticojejunostomy Procedure? A Tale Involving the Tail of the Pancreas

Recurrent acute pancreatitis (RAP) involving the tail of the pancreas after pancreaticojejunosotomy (PJP) is rare, has very challenging management, and there is minimal literature. We describe a case of idiopathic RAP, complicated with chronic pancreatitis that failed medical and endoscopic management and required PJP. Unfortunately, RAP recurred after PJP, and we describe his clinical course and management.

Surgical treatment for chronic pancreatitis: A single-center retrospective study in Japan

BACKGROUND/PURPOSE

To determine the short- and long-term results of surgical treatments for chronic pancreatitis (CP) at a high-volume center in Japan.

METHODS

The records of 151 consecutive patients undergoing surgery for CP were retrospectively reviewed. Selection of surgical procedures used had been according to the Japanese Clinical Practice Guidelines for CP 2015. Long-term (≥1 year) follow-up was performed in 100 patients (median of 37 months).

RESULTS

Surgical drainage procedures were performed in 107 patients (Frey operation in 81, longitudinal pancreaticojejunostomy in 26), pancreatic resection in 37 (subtotal stomach-preserving pancreaticoduodenectomy in 11, distal pancreatectomy in 26), and other procedures in six. The rates of postoperative mortality and morbidity were 1% and 26%, respectively. The rates of complete and partial pain relief were 62% and 37%. The frequency of occurrence of severe morbidity was significantly higher after pancreatic resection than in patients receiving drainage procedures (13% vs 2%, P = .019). The rate of new-onset diabetes was also significantly higher after resection than drainage (60% vs 25%, P = .017).

CONCLUSIONS

Surgical treatment for painful chronic pancreatitis can be safe and effective. An optimal procedure should guarantee pain relief and preserve a maximum of pancreatic function.

Laparoscopic longitudinal pancreaticojejunostomy for chronic pancreatitis: Systematic review of the literature

BACKGROUND

Longitudinal pancreaticojejunostomy, also known as modified Puestow or Partington-Rochelle procedure, is a technique for the treatment of chronic pancreatitis. It is usually performed by laparotomy, but in a very small number of cases it has been performed using a laparoscopic or robot-assisted approach. We carried out a systematic literature review to clarify the current status of laparoscopic longitudinal pancreatojejunostomy (LLPJ).

METHODS

Adhering to the PRISMA guidelines, a systematic search for LLPJ was performed in PubMed, Embase, and Cochrane Library, for articles published up to 31 December 2017.

RESULTS

357 articles were evaluated for eligibility and 17 were included for critical appraisal: eight case reports, eight retrospective case series, and one series of cases and controls without randomization. All of them had a grade of recommendation C and a level of evidence 4 according to the CEBM. Patients were relatively young (mean age 37 years), with a slight preponderance of males (ratio 1.3: 1). All had long-standing disease, ERCP prior to surgery and a dilated pancreatic duct (mean 11 mm). The surgery was usually performed laparoscopically using four trocars; the conversion rate was low (5%), bleeding was minimal, the morbidity rate was 11% and no mortality was reported. Mean hospital stay was 5.6 days. The follow-up period varied but was usually short (less than two years). The results for pain control were very good since 90% of patients reported no pain, although visual analog scales were rarely used.

CONCLUSIONS

In conclusion, LLPJ seems to be a safe, feasible and effective technique in patients with chronic pancreatitis. However, the number of descriptions published to date is very small, and there are no studies with high scientific evidence comparing LLPJ with open surgery or with endoscopic treatment that would allow us to draw firmer conclusions at the present time.

Endoscopic and surgical treatment options for chronic pancreatitis: an imaging perspective

Chronic pancreatitis is a chronic fibro-inflammatory syndrome characterized by chronic pancreatic inflammation leading to fibrosis and scarring. Patients with this multifactorial debilitating illness often require endoscopic or surgical intervention for treatment. Radiologists play a crucial role in pre-therapeutic workup as well as post-treatment imaging of chronic pancreatitis. This review summarizes the most common surgical and endoscopic treatment options that are currently available for chronic pancreatitis, including the implications on imaging.

Drainage procedure for pancreatolithiasis: re-examination of the pancreatic duct diameter standard

Purpose

Pancreatic duct decompression relieves pancreatic duct stone (PDS)-associated abdominal pain, though a consensus indication for the drainage procedure of the main pancreatic duct (MPD) is lacking. Moreover, major prognostic factors for postsurgical long-term pain relief and recurrence are largely unknown.

Methods

The clinical outcomes of 65 consecutive PDS patients undergoing surgery from 2008–2012 with 3+ years of follow-up were assessed.

Results

At postsurgical follow-up (median, 4.5 years; range, 3–7 years; procedure: Partington, n = 32; Frey, n = 27; pancreatoduodenectomy, n = 3; distal pancreatectomy, n = 3), the early complication and complete stone clearance rates were 29.2% and 97%, respectively. Long-term, complete and partial pain relief were 93.9%, 83.1%, and 10.8%, respectively. The risk of pancreatic fistula was higher in the <8 mm group than in the >8 mm group (P < 0.05), and 80% of the pancreatic fistula cases occurred in the <8 mm group. A shorter pain duration (P = 0.007), smaller MPD diameter (P = 0.04), and lower Izbicki pain score (P < 0.001) predicted long-term pain relief. Pain recurrence after initial remission occurred in 5 patients and was only related to pain duration (P = 0.02). Stone recurrence and pancreatic exocrine functional and endocrine functional deterioration occurred in 2, 5, and 11 patients, respectively.

Conclusion

Surgery provides excellent stone clearance, long-term pain relief, and acceptable postoperative morbidity. Using 8 mm as the criterion for drainage surgery can minimize the postoperative pancreatic fistula risk. Individualized and timely surgical treatment may improve the effect of surgery.

International consensus guidelines for surgery and the timing of intervention in chronic pancreatitis

BACKGROUND/OBJECTIVES

Chronic pancreatitis (CP) is a complex inflammatory disease with pain as the predominant symptom. Pain relief can be achieved using invasive interventions such as endoscopy and surgery. This paper is part of the international consensus guidelines on CP and presents the consensus guideline for surgery and timing of intervention in CP.

METHODS

An international working group with 15 experts on CP surgery from the major pancreas societies (IAP, APA, JPS, and EPC) evaluated 20 statements generated from evidence on 5 questions deemed to be the most clinically relevant in CP. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach was used to evaluate the level of evidence available for each statement. To determine the level of agreement, the working group voted on the 20 statements for strength of agreement, using a nine-point Likert scale in order to calculate Cronbach's alpha reliability coefficient.

RESULTS

Strong consensus was obtained for the following statements: Surgery in CP is indicated as treatment of intractable pain and local complications of adjacent organs, and in case of suspicion of malignant (cystic) lesion; Early surgery is favored over surgery in a more advanced stage of disease to achieve optimal long-term pain relief; In patients with an enlarged pancreatic head, a combined drainage and resection procedure, such as the Frey, Beger, and Berne procedure, may be the treatment of choice; Pancreaticoduodenectomy is the most suitable surgical option for patients with groove pancreatitis; The risk of pancreatic carcinoma in patients with CP is too low (2% in 10 year) to recommend active screening or prophylactic surgery; Patients with hereditary CP have such a high risk of pancreatic cancer that prophylactic resection can be considered (lifetime risk of 40-55%). Weak agreement for procedure choice in patients with dilated duct and normal size pancreatic head: both the extended lateral pancreaticojejunostomy and Frey procedure seems to provide equivalent pain control in patients.

CONCLUSIONS

This international expert consensus guideline provides evidenced-based statements concerning key aspects in surgery and timing of intervention in CP. It is meant to guide clinical practitioners and surgeons in the treatment of patients with CP.

Pancreatoscopy in endoscopic treatment of pancreatic duct stones: a systematic review

INTRODUCTION

Treatment of chronic calcifying pancreatitis is challenging and requires an interdisciplinary approach including endoscopist, surgeon and radiologist. With advances in endoscopic technology therapeutic interventions in the pancreatic duct became available. Extracorporeal shock wave lithotripsy (ESWL) is still recommended to be first line treatment, hence peroral pancreatoscopy- (POP) -guided intracorporal lithotripsy is a promising supplement in endoscopic therapy especially if ESWL is unsuccessful or not available.

EVIDENCE AQUISITION

Evidence from published trials, abstracts and case reports on direct pancreatoscopic treatment of main pancreatic duct (MPD) stones was reviewed with focus on efficiency and safety of available technologies, endoscopes and lithotripsy devices. A systematic Medline and Cochrane Database search for relevant studies was performed.

EVIDENCE SYNTHESIS

Seventeen relevant publications meeting the inclusion criteria have been identified (two prospective series, seven retrospective trials, six case reports, two abstracts, for a total of 225 patients). Successful ductal clearance for POP-guided treatment was reported between 37.5% and 100%. Clinical success was reported between 74% and 100%. Adverse event (AE) rate for POP-guided therapy is reported with 0-30%. There is no reported mortality following POP treatment. Three ongoing trials found to be registered.

CONCLUSIONS

POP-guided lithotripsy seems to be a promising alternative in a very selected patient cohort. Good powered randomized controlled trials are needed to prove efficiency and safety of the new technique also for large numbers of patients before it can be recommended as general practice. The focus of future studies should not only be on technical success, but also clinical success and patient-reported outcomes (quality of life).

Endoscopic treatment of pancreatic duct stones under direct vision: Revolution or resignation? Systematic review

BACKGROUND AND AIM

The main treatment aim in chronic pancreatitis (CP) is symptom control and especially pain relief. Management of stone-predominant CP is challenging and requires a multidisciplinary approach. Extracorporeal shock wave lithotripsy (ESWL) has emerged as the cornerstone of non-surgical treatment as a result of disappointing results of available endoscopic treatment options during the last decades. With new developments in the field of direct peroral pancreatoscopy (POP) and intracorporeal lithotripsy, direct intraluminal treatment of main pancreatic duct (MPD) stones returns to the spotlight.

METHODS

Herein, we reviewed the current data on direct pancreatoscopic treatment of MPD stones with a focus on efficiency and safety of available technologies, endoscopes and lithotripsy devices. A systematic Medline search for relevant studies was done.

RESULTS

Ten relevant publications meeting the inclusion criteria were identified (two prospective series, six retrospective trials, two case reports, n = 87 patients). Successful ductal clearance for POP-guided treatment was reported as between 43% and 100% compared to ESWL with 59% to 80%. Adverse event rate for POP-guided therapy was reported as 0-13.5%. One study showed a noticeable higher adverse event rate of 43%. In this trial, POP was carried out after ESWL. There is no reported mortality following POP treatment.

CONCLUSION

Available results are promising in terms of ductal clearance and pain relief compared to standard endoscopic techniques and ESWL as the current gold standard for lithotripsy. Interpretation of this data is limited by the small number of cases for POP and the lack of prospective randomized controlled trials.

Chronic pancreatitis: Multicentre prospective data collection and analysis by the Hungarian Pancreatic Study Group

INTRODUCTION

Chronic pancreatitis is an inflammatory disease associated with structural and functional damage to the pancreas, causing pain, maldigestion and weight loss and thus worsening the quality of life.

AIMS AND METHODS

Our aim was to find correlations from a multicentre database representing the epidemiological traits, diagnosis and treatment of the disease in Hungary. The Hungarian Pancreatic Study Group collected data prospectively from 2012 to 2014 on patients suffering from chronic pancreatitis. Statistical analysis was performed on different questions.

RESULTS

Data on 229 patients (74% male and 26% female) were uploaded from 14 centres. Daily alcohol consumption was present in the aetiology of 56% of the patients. 66% of the patients were previously treated for acute exacerbation. One third of the patients had had previous endoscopic or surgical interventions. Pain was present in 69% of the cases, endocrine insufficiency in 33%, diarrhoea in 13% and weight loss in 39%. Diagnosis was confirmed with US (80%), CT scan (52%), MRI-MRCP (6%), ERCP (39%), and EUS (7,4%). A functional test was carried out in 5% of the patients. In 31% of the cases, an endoscopic intervention was performed with the need for re-intervention in 5%. Further elective surgical intervention was necessitated in 44% of endoscopies. 20% of the registered patients were primarily treated with surgery. The biliary complication rate for surgery was significantly smaller (2%) than endoscopy (27%); however, pancreatic complications were higher in the patients treated with surgery. Patients who smoked regularly needed significantly more surgical intervention following endoscopy (66.7% vs. 26.9%, p = 0.002) than non-smokers, and the ratio of surgical intervention alone was also significantly higher (27.3% vs. 10.8%, p = 0.004). The ratio of surgery in patients who smoked and drank was significantly higher (30.09% vs. 12.5%, p = 0.012) than in abstinent and non-smoking patients, similarly to the need for further surgical intervention after endoscopic treatment (71.43% vs. 27.78%, p = 0.004).

CONCLUSIONS

According to the data analysed, the epidemiological data and the aetiological factors in our cohort differ little from European trends. The study highlighted the overuse of ERCP as a diagnostic modality and the low ratio of use of endoscopic ultrasonography. The results proved that alcohol consumption and smoking represent risk factors for the increased need for surgical intervention. Chronic pancreatitis should be treated by multidisciplinary consensus grounded in evidence-based medicine.

Role of original and modified Frey's procedures in chronic pancreatitis

AIM

To retrospectively review patients with chronic pancreatitis (CP) treated with Frey’s procedures between January 2009 and January 2014.

METHODS

A retrospective review was performed of patients with CP treated with Frey’s procedures between January 2009 and January 2014 in the Department of Pancreatic Surgery. A cross-sectional study of postoperative pain relief, quality of life (QoL), and alcohol and nicotine abuse was performed by clinical interview, letters and telephone interview in January 2016. QoL of patients was evaluated with the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) version 3.0. The patients were requested to fill in the questionnaires by themselves via correspondence or clinical interview.

RESULTS

A total of 80 patients were enrolled for analysis, including 44 who underwent the original Frey’s procedure and 36 who underwent a modified Frey’s procedure. The mean age was 46 years in the original group and 48 years in the modified group. Thirty-five male patients (80%) were in the original group and 33 (92%) in the modified group. There were no differences in the operating time, blood loss, and postoperative morbidity and mortality between the two groups. The mean follow-up was 50.3 mo in the original group and 48.7 mo in the modified group. There were no differences in endocrine and exocrine function preservation between the two groups. The original Frey’s procedure resulted in significantly better pain relief, as shown by 5-year follow-up (P = 0.032), better emotional status (P = 0.047) and fewer fatigue symptoms (P = 0.028). When stratifying these patients by the M-ANNHEIM severity index, no impact was found on pain relief after the two types of surgery.

CONCLUSION

The original Frey’s procedure is as safe as the modified procedure, but the former yields better pain relief. The severity of CP does not affect postoperative pain relief.

Evaluation of Pain Preoperatively and Postoperatively in Patients with Chronic Pancreatitis Undergoing Longitudinal Pancreaticojejunostomy

Chronic pancreatitis is a fairly common condition with pain being the major symptom, and longitudinal pancreaticojejunostomy (LPJ) is performed for symptomatic relief. The aim of the study is to assess relief of pain post-LPJ for chronic pancreatitis and to evaluate the factors influencing relief of symptoms. A prospective observational non-interventional study enrolling 28 patients. This study involved a questionnaire studying various risk factors and pain related to chronic pancreatitis, pancreaticojejunostomy, and postoperative assessment of pain relief at 1 and 6 months from surgery. Pain was assessed using Visual analogue scale (VAS). In chronic pancreatitis, there is a significant relief in symptoms of pain post-LPJ; the degree of relief was less in the alcoholics vs non-alcoholics (p = 0.09) and smokers. There was also reduction in analgesic requirement and frequency of acute attacks of pain. Fifty-seven percent of patients had a complete remission of their pain after LPJ for CP. In chronic pancreatitis, there is a significant relief in symptoms of pain post-LPJ, although the degree of relief is less in the alcoholics and smokers.

Surgery remains the best option for the management of pain in patients with chronic pancreatitis: A systematic review and meta-analysis

Controversy related to endoscopic or surgical management of pain in patients with chronic pancreatitis remains. Despite improvement in endoscopic treatments, surgery remains the best option for pain management in these patients.

Short- and long-term results of the Frey procedure for chronic pancreatitis

BACKGROUND

The aim of this study was to determine the short- and long-term results of the Frey procedure for chronic pancreatitis.

METHODS

From November 1998 to December 2013, 41 patients underwent the Frey procedure for painful chronic pancreatitis at Kyushu University Hospital. The short- and long-term results of the Frey procedure including mortality, morbidity, pain relief, weight gain and pancreatic endocrine function were analyzed. The long-term results were analyzed in 29 patients who had been followed-up for more than 12 months. The long-term follow-up rate was 85%.

RESULTS

There was no mortality. Early postoperative complications occurred in seven patients (17%), including pancreatic fistula in four (10%, International Study Group of Pancreatic Fistula ISGPF grade B) and hemorrhage in three (7%). Long-term relief of abdominal pain was achieved in 90% (26/29) of cases. One patient developed relapse of inflammation of the head of pancreas during the follow-up period, necessitating pylorus-resecting pancreatoduodenectomy. Only two patients (7%) developed new-onset diabetes mellitus after the Frey procedure during the follow-up period.

CONCLUSIONS

The Frey procedure for painful chronic pancreatitis may be safe and pancreatic endocrine function is preserved. Complete decompression of the pancreatic ducts in the head of pancreas and full length drainage of the main pancreatic duct from the head of pancreas to the tail may be important in the Frey procedure to prevent recurrence of acute inflammation.

Endoscopic therapy for chronic pancreatitis

Endoscopic therapy is recommended as the first-line therapy for painful chronic pancreatitis with an obstacle on the main pancreatic duct (MPD). The clinical response should be evaluated at 6 to 8 weeks. Calcified stones that obstruct the MPD are first treated by extracorporeal shockwave lithotripsy; dominant MPD strictures are optimally treated with a single, large, plastic stent that should be exchanged within 1 year even in asymptomatic patients. Pancreatic pseudocysts for which therapy is indicated and are within endoscopic reach should be treated by endoscopy.

Is endoscopic therapy the treatment of choice in all patients with chronic pancreatitis?

Chronic pancreatitis (CP) is a progressive inflammatory disease of the pancreas characterized by destruction of the pancreatic parenchyma with subsequent fibrosis that leads to pancreatic exocrine and endocrine insufficiency. Abdominal pain and local complications (bile duct or duodenal stenosis and pancreatic tumor) secondary to CP are indications for therapy. At the beginning, medical therapy is used. More invasive treatment is recommended for patients with pancreatic duct stones (PDS) and pancreatic obstruction in whom standard medical therapy is not sufficient. Recently, Clarke et al assessed the long-term effectiveness of endoscopic therapy (ET) in CP patients. The authors compared ET with medical treatment. They reported that ET was clinically successful in 50% of patients with symptomatic CP. In this commentary, current CP treatment, including indications for ET and surgery in CP patients, is discussed. Recommendations for endoscopic treatment of CP according to the European Society of Gastrointestinal Endoscopy Clinical Guidelines are reviewed. Different surgical methods used in the treatment of CP patients are also discussed. ET is the most useful in patients with large PDS, pancreatic duct obstruction and dilation. It should be the first-line option because it is less invasive than surgery. Surgery should be the first-line option in patients in whom ET has failed or in those with a pancreatic mass with suspicion of malignancy. ET is a very effective and less invasive procedure, but it cannot be recommended as the treatment of choice in all CP patients.

The Spanish Pancreatic Club's recommendations for the diagnosis and treatment of chronic pancreatitis: part 2 (treatment)

Chronic pancreatitis (CP) is a complex disease with a wide range of clinical manifestations. This range comprises from asymptomatic patients to patients with disabling symptoms or complications. The management of CP is frequently different between geographic areas and even medical centers. This is due to the paucity of high quality studies and clinical practice guidelines regarding its diagnosis and treatment. The aim of the Spanish Pancreatic Club was to give current evidence-based recommendations for the management of CP. Two coordinators chose a multidisciplinary panel of 24 experts on this disease. These experts were selected according to clinical and research experience in CP. A list of questions was made and two experts reviewed each question. A draft was later produced and discussed with the entire panel of experts in a face-to-face meeting. The level of evidence was based on the ratings given by the Oxford Centre for Evidence-Based Medicine. In the second part of the consensus, recommendations were given regarding the management of pain, pseudocysts, duodenal and biliary stenosis, pancreatic fistula and ascites, left portal hypertension, diabetes mellitus, exocrine pancreatic insufficiency, and nutritional support in CP.

Improved quality of life following total pancreatectomy and auto-islet transplantation for chronic pancreatitis

BACKGROUND

Total pancreatectomy (TP) with auto-islet transplant (AIT) is an extreme treatment for chronic pancreatitis, and we reviewed our experience to assess the impact on quality of life (QOL).

METHODS

A prospective cohort study from 2007 through 2010 with pre- and postoperative assessments of the Depression Anxiety Stress Scale, Pain Disability Index, and visual analogue pain scale was performed.

RESULTS

Twenty patients underwent TP-AIT with a median follow-up of 12 months (6.75-24 months). All patients reported moderate (45 %) to severe (55 %) pain prior to surgery. TP-AIT resulted in significant decreases in abdominal pain (p < 0.001), 80 % reporting no or mild pain. Despite pain improvement, only 30 % discontinued narcotics. Improvements in all PDI QOL domains improved from 79 to 90 % (p = 0.002), with greatest improvements seen in those without prior pancreatic surgery, younger patients, and in those with higher levels of preoperative pain. Patients were less affected by depression and anxiety prior to surgery, but 60 and 70 % did show improvement in depression and anxiety, respectively (p = 0.033). Sixteen patients (80 %) required exogenous insulin at last follow-up (mean total dose of insulin 11.6 U/day).

CONCLUSIONS

TP-AIT significantly improves pain and QOL measures in appropriately selected patients with CP.

Functional and medical outcomes after tailored surgery for pain due to chronic pancreatitis

OBJECTIVE

We measured a comprehensive set of outcome measures after different surgical procedures for painful chronic pancreatitis (CP) at long-term follow-up.

BACKGROUND

Pain caused by CP can be alleviated through operative intervention with type of procedure depending on anatomical abnormalities. Outcome measures include functional (pain relief, quality of life [QoL]), medical (endo- and exocrine function), and clinical (reoperation) results reported by patient.

METHODS

A cross-sectional cohort of 223 consecutive patients who underwent surgical drainage, head resection, or left-sided pancreas resection, depending on anatomical abnormalities, was analyzed. Participating patients were reassessed during a prospectively scheduled outpatient clinic visit.

RESULTS

At follow-up, 44 patients had died; 146 of 179 living patients consented to participate in the study. After 63 months (range: 14-268), 68% reported no or little pain, 19% reported intermediate pain, and 12% reported severe pain. Preoperative daily opioid use (OR: 3.04; 95% confidence interval [CI]: 1.09-8.49) and high numbers of preceding endoscopic procedures (OR [odds ratio]: 3.89; 95% CI: 1.01-14.9) were associated with persistent severe pain. Compared with the general population, physical more than mental QoL remained impaired (P < 0.05). At follow-up, endocrine insufficiency was present in 57% of patients and exocrine insufficiency was present in 77%. Independently, a head resection and a reoperation for any cause were moderately associated with new-onset diabetes (P < 0.1). Compared with patients who underwent left-sided resection, the risk of developing exocrine insufficiency after surgery was higher after drainage or head resection. After 20 months (interquartile range: 10-51) after surgery, 26 (12%) of 223 patients underwent 1 or more elective reoperations.

CONCLUSIONS

Operative intervention for painful CP, tailored to anatomical abnormalities, results in excellent to fair long-term pain relief, but approximately 10% of patients do not respond. QoL scores remained slightly compromised. High preoperative pain levels, suggested through daily opioid use and high numbers of endoscopic procedures, are associated with less favorable outcome.

Laparoendoscopic single-site lateral pancreaticojejunostomy

BACKGROUND

Chronic pancreatitis is mainly managed with drugs, but surgery is required in selected groups of patients. The Partington procedure is still the procedure of choice for patients with a dilated main pancreatic duct but without an inflammatory pancreatic head mass. The same equivalent can be achieved by laparoscopic approach. Laparoendoscopic single-site surgery gained tremendous attention in the past few years. Complex surgeries are being reported using this technique. We report in this paper the first laparoendoscopic single-site lateral pancreaticojejunostomy (LPJ) for chronic calcific pancreatitis with dilated pancreatic duct.

PATIENT AND METHOD

The procedure was performed on a 32-year-old female diagnosed to have chronic calcific pancreatitis. A single vertical 2.5-cm umbilical incision and one 10-mm and two 5-mm ports were made. The procedure was completed in 220 min without any intraoperative complication. There were no postoperative complications, and the patient was discharged on day 5 when she started taking routine diet.

CONCLUSION

This preliminary experience suggests that single-incision laparoscopic LPJ is feasible and safe when performed by an experienced laparoscopic surgeon. It has a cosmetic advantage over laparoscopic LPJ. However, it remains to be determined if this technique offers additional advantages of decreased analgesia, decreased hospital stay or cost effectiveness. Further studies are required to analyze these factors.
