ObjectiveTo evaluate the causes, clinical features, diagnosis and treatment of chronic pancreatitis (CP). MethodsWe retrospectively analyzed the clinical features of 47 patients with CP in the Sixth People's Hospital of Chengdu City from February 2008 to December 2011. ResultsThere were 24 cases of biliary pancreatitis (51.1%), and 17 cases of alcoholic pancreatitis (36.2%). The clinical manifestations included abdominal pain in 40 patients (87.2%), diarrhea in 12 patients (25.5%), and diabetes mellitus in 13 patients (27.6%). Sixteen patients were diagnosed based on the ultrasonographic results (34.0%), 41 by computed tomography (CT) (87.2%), and 31 by endoscopic retrograde cholangiopancreatography (ERCP) (88.6%). Plain abdominal radiograph showed that 9 patients had calcification, mainly composed of Ⅰ and Ⅱ classes (44.7% and 51.1%), followed by class Ⅳ and stage 3. Management for chronic pancreatitis included medical treatment (10 cases, 21.2%) and surgical treatment (13 case, 27.6%), endoscopic treatment (24 cases, 51.6%). ConclusionThe causes of chronic pancreatitis are biliary and alcoholic factors. Medical, endoscopic and surgical procedures are involved to treat chronic pancreatitis, especially for the relief of intractable chronic abdominal pain.
ObjectiveTo explore the advantages and disadvantages of duodenum-preserving pancreatic head resection (DPPHR) in the clinical application of pancreatic surgical diseases, and to summarize the progress of minimally invasive application of DPPHR combined with the current application of laparoscopy and robot surgery in pancreatic surgery. MethodThe related research literatures about DPPHR at home and abroad in recent years were searched and reviewed. ResultsThe effect of DPPHR compared with traditional pancreaticoduodenectomy (PD) for treatment of benign pancreatic diseases was still controversial, and the postoperative remission effect, perioperative period, occurrence of long-term complications and improvement of quality of life were not very advantageous compared with PD, and the prognosis of minimally invasive surgery was poor. ConclusionDPPHR remains highly controversial for surgical intervention in benign pancreatic disease and has enormous scope for advances in minimally invasive surgical applications in pancreatic surgery, but more clinical studies are needed to verify its clinical efficacy.
The course of chronic pancreatitis is prolonged, and pain is the main symptom, which seriously affects the quality of life and work ability of patients. Its treatment is the most important and complex problem. This article systematically describes the theoretical basis, indications, efficacy, selection and balance of drugs, endoscopy, surgery and other measures related to pain treatment.
Objective To summarize current research advances of mechanism and treatment of pancreatic endocrine and exocrine insufficiency in chronic pancreatitis. Method The related literatures about the research progress of the pancreatic endocrine and exocrine insufficiency in the chronic pancreatitis in recent years were retrieved and reviewed. Results In recent years, it had many new studies and discoveries on the pancreatic endocrine and exocrine insufficiency in the chronic pancreatitis. The mechanism of the pancreatic exocrine dysfunction was mainly due to the decrease of the pancreatin secretion in the patients with chronic pancreatitis. The mechanism of the pancreatic endocrine insufficiency was mainly due to the damage of the pancreatic exocrine gland and islet tissue in the chronic pancreas, which leaded to the destruction of the pancreatic endocrine cells, the other endocrine cells, and the disturbance of the intestine-islet axis, followed by the disorder of the various hormones (insulin, glucagon, pancreatic polypeptide, etc.), and eventually manifested the glucose tolerance or dominant diabetes. Conclusions At present, although there is a certain degree understanding for pancreatic endocrine and exocrine insufficiency in chronic pancreatitis, there are no breakthroughs in its mechanism and treatment, and effect is lack of large sample and multicenter clinical control study. Exploring more optimized detection methods and establishing a perfect treatment system is goal of future development and research.
Objective To explore the effect of Frey procedure on patients with chronic pancreatitis, and evaluate pain control as well as the quality of life (QOL) after Frey procedure. Methods The clinical data of 81 patients with chronic pancreatitis who underwent Frey procedure in West China Hospital of Sichuan University from January 2010 to January 2015 were retrospectively analyzed. Izbicki pain score and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC-QLQ-C30) were used to assess pain and QOL respectively. Results The mean value of operative time were (252±70) minutes (180-430 minutes), the mean value of blood loss were (220±142) mL (100-550 mL), and the mean value of hospital stay were (14.1±4.9) days (8-36 days). After Frey procedure, delayed gastric emptying occurred in 4 patients, hemorrhage occurred in 1 patient, wound infection or fat liquefaction occurred in 6 patients, abdominal infection and pyoperitoneum occurred in 4 patients, and pancreatic fistula occurred in 3 patients. All of the patients were followed up for 4-60 months, and the median time were 28 months. During the follow up period, 11 patients developed diabetes and 10 patients developed steatorrhea, respectively. In addition, the pain related score, including frequency of pain attacks, visual analogue scale of pain, analgetic medication, inability to work, and total pain score, were significantly reduced after Frey procedure (P＜0.001). Moreover, all the functional scales of EORTC -QLQ-C30, except for cognitive function, were improved postoperatively (P ＜0.001). Regarding to the symptom scales, the score of fatigue, pain, loss of appetite, and loss of body weight were significantly lower after surgery (P＜0.050). The scores of QOL after surgery were higher than before surgery (P＜0.001). Conclusion Frey procedure results in good post-operative pain control and significant improvement in qol.

To evaluate the present status of treatment of chronic pancreatitis, 116 consecutive patients with chronic pancreatitis during the last decade (1986～1996) have been surveyed retrospectively. The clinical date has been analized statisticaly. Etiology: biliogenic 56 cases (48.3%), alcoholic 17 (14.6%), idiopathic 34 (29.3%) and other 9 cases (7.8%). Better result was achieved in surgical treatment group (81 cases) than in conservative group (35 cases), pain free: 65.5% vs 33.3%. The accumulated five-year survival rate was 56.3%, 92.2% and 78.1% in alcoholic, billiogenic and idiopathic type of chronic pancreatitis respectively. Morbidity and mortality of diarrhea and diabetes mellitus increased at followup. The authors conclude that the chronic pancreatitis patients associated with obstruction of biliopancreatic duct should undergo operation early and will ameliorate abdominal pain.
ObjectiveTo investigate the differential diagnosis of chronic pancreatitis with mass of pancreatic head and pancreatic carcinoma, and choose the effective treatment of chronic pancreatitis with mass of pancreatic head. MethodsEighty cases of chronic pancreatitis with mass of pancreatic head from January 2008 to January 2014 in this hospital were retrospectively analyzed.The preoperative blood tumor markers, hepatobiliary and pancreatic color Doppler ultrasound, CT strengthen, MRI, MRCP, or other imaging studies were tested for all the patients. ResultsThere were 4 cases of long-term drinking or excessive drinking history in 8 cases of chronic pancreatitis with mass of pancreatic head.The past medical history included 5 patients with acute pancreatitis, 3 patients with chronic cholecystitis, 2 patients with cholecystolithiasis.Six patients had varying degree of jaundice and 5 patients had left upper abdominal pain.There were 4 patients with high blood sugar, 6 patients with serum hyperbilirubin, 5 patients with elevated CA19-9 and 2 patients with elevated CEA by serum assay.The imaging revealed that a mass was in the head of the pancreas.The standard pancreaticoduodenectomy was performed in 6 cases, duodenum-preserving pancreatic head resection was performed in 2 cases.These 8 patients underwent the intraoperative fine needle aspiration cytological examination revealed the changes of chronic pancreatitis by postoperative pathology.The levels of CA19-9 and CEA on 1 week after operation were reduced to normal levels in patients with elevated CA19-9 and CEA alone or together.There was no case of serious complications such as postoperative pancreatic leakage and bile leakage.The intermittent vomiting appeared in 3 months after duodenum-preserving pancreatic head resection, the upper gastrointestinal radiography showed the stenosis of duodenum, the contrac-tures of the duodenum, especial the descending duodenum, was found through reoperation, the symptom was relief after gastrojejunal anastomosis.The recurrence was not seen in all these 8 patients with follow-up of 1-6 years. ConclusionsThe jaundice and abdominal for the patients with pancreatic head mass of chronic pancreatitis and pancreatic cancer pain are the main symptoms, but their characteristics are different, the former is minor, volatility, and intermittent; the latter is sustained and progressively aggravated.Understanding of past medical history for the identification of both is some significances.CA19-9 and CEA as the identification of the pancreatic head mass in chronic pancreatitis and pancreatic cancer is not meaningful.Patients with chronic pancreatitis of pancreatic mass are finished by multi-needle biopsy for pancreatic head mass, duodenum-preserving pancreatic head resection is preferred.Patients with invasive pancreatic mass and peripheral vascular adhesion must undergo standard pancreaticoduodenectomy.
Objective To investigate the magnetic resonance imaging （MRI） assessment and functional evaluation of chronic pancreatitis （CP）. Methods Literatures about MRI assessment of CP （especially the evaluation of pancreatic exocrine function with MRI） were reviewed. Results Some early parenchymal changes （pancreatic size，signal intensity of pancreas， and enhancement pattern） in the CP could be visualized by MRI；ductal changes could be visualized by MR cholangiopancreatography （MRCP）；and secretin-stimulated MRCP （combination of both morphologic and functional evaluation） not only improved the visualization of pancreatic duct and side branches，but also allowed evaluation of the pancreatic exocrine function noninvasively. Secretin-stimulated diffusion weighted imaging also could be used as a noninvasive method to assess pancreatic exocrine function. Conclusions Conventional MRI and （or） secretin-stimulated MRI can become valuable means in CP （especially early-stage CP）， with furnishing morphologic and functional information simultaneously. However，further research is needed to verify the diagnostic accuracy of these modalities.
