Minimally invasive percutaneous catheter drainage versus open laparotomy with temporary closure for treatment of abdominal compartment syndrome in patients with early-stage severe acute pancreatitis / 华中科技大学学报（医学）（英德文版）

This study aimed to examine the clinical efficacy of minimally invasive percutaneous catheter drainage (PCD) versus open laparotomy with temporary closure in the treatment of abdominal compartment syndrome (ACS) in patients with early-stage severe acute pancreatitis (SAP). Clinical data of 212 patients who underwent PCD and 61 patients who were given open laparotomy with temporary closure in our hospital over the last 10-year period were retrospectively analyzed, and outcomes were compared, including total and post-decompression intensive care unit (ICU) and hospital stays, physiological data, organ dysfunction, complications, and mortality. The results showed that the organ dysfunction scores were similar between the PCD and open laparotomy groups 72 h after decompression. In the PCD group, 134 of 212 (63.2%) patients required postoperative ICU support versus 60 of 61 (98.4%) in the open laparotomy group (P<0.001). Additionally, 87 (41.0%) PCD patients experienced complications as compared to 49 of 61 (80.3%) in the open laparotomy group (P<0.001). There were 40 (18.9%) and 32 (52.5%) deaths, respectively, in the PCD and open laparotomy groups (P<0.001). In conclusion, minimally invasive PCD is superior to open laparotomy with temporary closure, with fewer complications and deaths occurring in PCD group.

Etiology, pathology, management and prognosis of chronic pancreatitis in Chinese population: A retrospective study / 华中科技大学学报（医学）（英德文版）

The purpose of this study was to investigate the etiology, pathological characteristics, management and prognosis of chronic pancreatitis in the Chinese population. The clinical data of 142 patients with chronic pancreatitis were retrospectively studied. All patients were of Chinese nationality and hospitalized from January 2008 to December 2011. Their ages ranged from 14 to 76 years, with a mean of 43 years. Of 142 patients, there were 72 cases of obstructive chronic pancreatitis (50.70%), 19 cases of alcoholic chronic pancreatitis (13.38%), 14 cases of autoimmune pancreatitis (9.86%) and 37 cases of undetermined etiology (26.06%). Pathologically, the average inflammatory mass diameter was 3.8 ± 3.3 cm, biliary obstruction occurred in 36 cases, gall stones in 70 cases, calcification in 88 cases, ductal dilatation in 61 cases, side branch dilatation in 32 cases, ductal irregularity in 10 cases, lymphocytic inflammation in 23 cases, obliterative phlebitis in 14 cases, extra pancreatic lesion in 19 cases and fibrosis in 142 cases. Location of pancreatic lesion in the region of head (n=97), neck (n=16), body (n=12), tail (n=15) and whole pancreas (n=2) influenced the choice of surgical procedures. Ninety-four patients (66.20%) received surgical treatment and 33.80% received other treatments. After operation, 80.85% of 94 patients experienced decreased pain, and 8.51% of 94 showed recovery of endocrine function but with a complication rate of 12.77%. All the operations were performed successfully. According to the pain scale of European Organization for Research and Treatment of Cancer (QLQ-C30) a decrease from 76 ± 22 to 14 ± 18 was observed. Etiology, pathological characteristics, management and prognosis of chronic pancreatitis in the Chinese population vary from others.

Surgical treatment of chronic pancreatitis in young patients / 华中科技大学学报（医学）（英德文版）

The main treatment strategies for chronic pancreatitis in young patients include therapeutic endoscopic retrograde cholangio-pancreatography (ERCP) intervention and surgical intervention. Therapeutic ERCP intervention is performed much more extensively for its minimally invasive nature, but a part of patients are referred to surgery at last. Historical and follow-up data of 21 young patients with chronic pancreatitis undergoing duodenum-preserving total pancreatic head resection were analyzed to evaluate the outcomes of therapeutic ERCP intervention and surgical intervention in this study. The surgical complications of repeated therapeutic ERCP intervention and surgical intervention were 38% and 19% respectively. During the first therapeutic ERCP intervention to surgical intervention, 2 patients developed diabetes, 5 patients developed steatorrhea, and 5 patients developed pancreatic type B pain. During the follow-up of surgical intervention, 1 new case of diabetes occurred, 1 case of steatorrhea recovered, and 4 cases of pancreatic type B pain were completely relieved. In a part of young patients with chronic pancreatitis, surgical intervention was more effective than therapeutic ERCP intervention on delaying the progression of the disease and relieving the symptoms.

Indication and choice of operation technique for duodenum-preserving resection of pancreatic head: 22 cases reports / 中华外科杂志

<p><b>OBJECTIVE</b>To analyze the indication and choice of operation technique for duodenum-preserving resection of pancreatic head.</p><p><b>METHODS</b>The Clinical material of the 22 patients who received duodenum-preserving resection of pancreatic head (DPPHR) from January 2001 to January 2006 was analyzed. Of the 22 cases, 8 cases presented with mucinous cystadenoma, 2 cases with mucinous cystadenocarcinoma, 4 cases with solid-pseudopapillary tumors, 2 cases with pancreatic endocrine tumors, 4 cases with chronic pancreatitis, 1 case with lymph epidermis cyst, 1 case with serous cystadenoma. The indication, choice of operation technique of DPPHR and the prevention and management of the post-operative complications were investigated.</p><p><b>RESULTS</b>No patient died of the operation. Three cases (13.6%) developed pancreatic fistula after the operation, 1 case (4.5%) developed biliary fistula, 1 case (4.5%) developed abdominal infection and 2 cases of duodenal fistula occurred (9.1%).</p><p><b>CONCLUSIONS</b>DPPHR retains the continuity of stomach, duodenum and biliary ducts. The operation is safe and it reduces wounds and excision scope. This procedure can be used in benign and low malignant lesions in the head and neck of the pancreas.</p>

Clinical significance of the expression of MUC4 mRNA in peripheral blood mononuclear cells of pancreatic cancer patients / 中国医学科学院学报

<p><b>OBJECTIVE</b>To explore the expression and clinical significance of MUC4 mRNA in peripheral blood mononuclear cells of pancreatic cancer patients.</p><p><b>METHODS</b>The expression of MUC4 mRNA in peripheral blood mononuclear cells of pancreatic cancer patients were detected with reverse transcription realtime PCR.</p><p><b>RESULTS</b>Expression of MUC4 mRNA was not detected in the peripheral blood mononuclear cells of chronic pancreatitis patients and normal healthy people, but was observed in those of pancreatic cancer patients. The positive expression rate of MUC4 mRNA in pancreatic cancer patients was 60%, which was significantly higher than those of chronic pancreatitis patients and normal healthy people (P < 0.01). The positive expression rate of MUC4 mRNA increased with the development of clinical stage, and the positive expression rate in stage of II - IV (TNM system) was 76.92%, which was significantly higher than that of I - II stage (P < 0.01).</p><p><b>CONCLUSIONS</b>Expression of MUC4 mRNA is highly correlated with the clinical stage in pancreatic cancer patients. Detecting the expression of MUC4 mRNA in peripheral blood mononuclear cells of pancreatic cancer patients may be helpful for the early diagnosis and differential diagnosis.</p>
