The study was performed in 22 patients with pancreatic stones treated at Surgical Department of Bach Mai Hospital from May 1996 to July 2001. The study was to describe the clinical and paraclinical symptoms as well as the early outcome of wirsungotomy removing the calculi and pancreatico – jejunostomy. The result showed that the disease was more often seen in working ages; more male than females; clinical symptoms were not specific; diagnosis relied mainly on imagery examens. The pancreatolithotomy is effective operation and easy for patients and riquires futher surverying for long term evaluation.

Endoscopic therapy has been increasingly recognized as the effective therapy in selected patients with chronic pancreatitis. Utility of endotherapy in various conditions occurring in chronic pancreatitis is discussed. Its efficacy, limitations, and alternatives are addressed. For the best management of these complex entities, a multidisciplinary approach involving expertise in all pancreatic specialties is essential to achieve the goal.

A retrospective survey was conducted on 62 patients aged 20-70 years during the period from 1995-1997 with a gender ratio of 64.5%/34.5% (male/female). Subjects were diagnosed as bile duct occlusion icteria due to the tumors of pancreatic head. Not any surgical interventions were performed. Main clinical signs were progressive jaundice, no fever, weigh loss, white faeces, and large size of liver and pancreas. Hematological exams and imaging diagnosis including ultrasonography were carried out. Survival times of an average of 2.8 months for operable group and under 1 month for non operable group were noted

BACKGROUND/AIMS: Although a few recent studies have reported the effectiveness of endoscopic pancreatic sphincterotomy (EPST), none has compared physicians' skills and complications resulting from the procedure. Thus, we examined the indications, complications, and safety of EPST performed by a single physician at a single center. METHODS: Among 2,313 patients who underwent endoscopic retrograde cholangiopancreatography between January 1996 and March 2008, 46 patients who underwent EPST were included in this retrospective study. We examined the indications, complications, safety, and effectiveness of EPST, as well as the need for a pancreatic drainage procedure and the concomitant application of EPST and endoscopic sphincterotomy (EST). RESULTS: Diagnostic indications for EPST were chronic pancreatitis (26 cases), pancreatic divisum (4 cases), and pancreatic cancer (8 cases). Therapeutic indications for EPST were removal of a pancreaticolith (10 cases), stent insertion for pancreatic duct stenosis (9 cases), nasopancreatic drainage (7 cases), and treatment of sphincter of Oddi dysfunction (1 case). The success rate of EPST was 95.7% (44/46). Acute complications of EPST included five cases (10.9%) of pancreatitis and one of cholangitis (2.2%). EPST with EST did not reduce biliary complications. Endoscopic pancreatic drainage procedures following EPST did not reduce pancreatic complications. CONCLUSIONS: EPST showed a low incidence of complications and a high rate of treatment success; thus, EPST is a relatively safe procedure that can be used to treat pancreatic diseases. Pancreatic drainage procedures and additional EST following EPST did not reduce the incidence of procedure-related complications.

OBJECTIVETo explore the improvement of typing and reasonable surgical treatment for pancreatic ductal stone (PDS).

METHODSTotally 89 patients with pancreatic ductul stone treated underwent surgeries from January 2000 to December 2012 were involved into this study. There were 57 male and 32 female patients, the average age was (52 ± 23) years. According to the magnetic resonance cholangiopancreatography imaging and finding during surgery, pancreatolithiasis was classified into three types: type I, the stones were located in the main pancreatic duct; type II, the stones were located both in main and branch pancreatic duct; type III, the stones were diffusely scattered in the branch pancreatic duct; the position of PDS within pancreatic parenchyma were subtitled. In this group, 43 type I PDS were extracted with endoscopic papillotomy or endoscopic pancreatic sphincterotomy, or pancreatolithotomy plus pancreato-jejunal lateral anastomosis with wide anastomotic stoma; 39 type II cases were treated by pancreatolithotomy plus pancreato-jejunal lateral anastomosis or/and resection of pancreatic section; 7 type III PDS were managed with resection of pancreatic section.

RESULTSAll surgeries were performed successfully. Among complications, 6 cases (6.7%) were pancreatic leakage which recovered after systematic non-surgical treatment, 2 cases (2.2%) were anastomotic bleeding which led to 1 death, 6 cases (6.7%) were residual pancreatolithiasis in branch pancreatic duct type. Seventy-eight patients were followed up for 6 to 131 months, 57 cases were still alive so far. Five cases were intermittent abdominal pain, 7 cases were diabetes resulted from 2 subtotal pancreatectomy and 5 distal pancreatectomy, 5 cases occurred pancreatolithiasis recurrence and 3 underwent secondary surgeries.

CONCLUSIONSThe basis of this modified typing of pancreatolithiasis is the position of stone in pancreatic duct rather than pancreas parenchyma. It is more important and valuable for surgical principle of taking stones out completely and maintaining pancreatic function.

Objective: To compare and analyze the clinical efficacy of pancreaticoduodenectomy for distal bile duct cancer and pancreatic head cancer. Methods: Clinical data of 1 005 patients who underwent pancreaticoduodenectomy and postoperative pathological examination confirmed the diagnosis of distal bile duct cancer and pancreatic head cancer at the Pancreas Center of the First Affiliated Hospital of Nanjing Medical University from January 2016 to December 2020 were analyzed retrospectively. There were 112 cases in the distal bile duct cancer group, 71 males and 41 females,with age (M(IQR)) of 65(15) years(range: 40 to 87 years); 893 cases in the pancreatic head cancer group, 534 males and 359 females,with age of 64(13)years(range: 16 to 91 years). The differences between clinicopathological characteristics and postoperative overall survival of the two groups were analyzed by χ² test, Fisher's exact probability method, rank sum test or log-rank test, respectively. The difference in postoperative overall survival between the two groups was compared using Kaplan-Meier method after propensity score matching (1∶1). Results: Compared with the pancreatic head cancer group,the distal bile duct cancer group had shorter operative time (240.0(134.0) minutes vs. 261.0(97.0) minutes, Z=2.712, P=0.007),less proportion of combined venous resection (4.5% (5/112) vs. 19.4% (173/893), χ²=15.177,P<0.01),smaller tumor diameter (2.0(1.0) cm vs. 3.0(1.5) cm,Z=10.567,P<0.01),higher well/moderate differentiation ratio (51.4% (56/112) vs. 38.0% (337/893), χ²=7.328, P=0.007),fewer positive lymph nodes (0(1) vs. 1(3), Z=5.824, P<0.01),and higher R0 resection rate (77.7% (87/112) vs. 38.3%(342/893), χ²=64.399, P<0.01),but with a higher incidence of overall postoperative complications (50.0% (56/112) vs. 36.3% (324/892), χ²=7.913,P=0.005),postoperative pancreatic fistula (28.6% (32/112) vs. 13.9% (124/893), χ²=16.318,P<0.01),and postoperative abdominal infection (21.4% (24/112) vs. 8.6% (77/892), χ²=18.001,P<0.01). After propensity score matching, there was no statistical difference in postoperative overall survival time between patients in the distal bile duct cancer group and the pancreatic head cancer group (50.6 months vs. 35.1 months,Z=1.640,P=0.201),and multifactorial analysis showed that tumor site was not an independent risk factor affecting the prognosis of patients in both groups after matching (HR=0.73,95%CI:0.43 to 1.23,P=0.238). Conclusions: Patients with distal bile duct cancer are more likely to benefit from early diagnosis and surgical treatment than patients with pancreatic head cancer,but with a relative higher postoperative complication rates. The different tumor origin site is not an independent risk factor for prognosis of patients with distal bile duct cancer and pancreatic head cancer after propensity score matching.

OBJECTIVETo study the feasibility of binding pancreatic duct to mucosa anastomosis (BDM)-a complementary procedure to both binding pancreaticojejunostomy and binding pancreaticogastrostomy.

METHODS(1) Animal experimental study:gastrostomy and jejunostomy were performed on six adult New Zealand rabbits. The gastrostomy and jejunostomy shared a same stent (rubber urethral catheter, silicone tube or plastic infusion tube). Both ends of the stent were placed in gastric and enteric cavity. Purse-string suture was performed around the stent before the jejunum and the stomach were brought together for fixation by few stitches. And to observe whether the purse-string suture around a plastic tube, rubber tube or silicon tube inserted into jejunum and/or stomach can prevent leaking out of the jejunal or gastric content to cause peritonitis. (2) Clinically 7 patients were performed with BDM anastomosis. The procedure was consisted of five steps: preparation of the pancreatic stump;preparation of the jejunum; preparation of the fixing sutures between the pancreatic stump and the jejunum; implementation of the anastomosis; lastly, fixation of the jejunum beside the pancreas stump. Post-operative periodic examination of the blood amylase and the amylase in the abdominal drainage. Pancreatic fistula was classified in to two categories: parenchymal fistula (pancreatic cut surface fistula) and anastomotic leakage.

RESULTSAnimal experiment did not show any leakage around the plastic tube or silicon tube inserted into jejunum and(or) stomach. There was no anastomotic leak in all the patients. There was transient increase of amylase in two cases, but the volume of drainage did not exceed 50 ml/d and the recovery of the patients was not affected.

CONCLUSIONSBDM is a simple, safe and easy procedure to perform. It provides to the surgeons with a new option in different situations to achieve the most ideal surgical result.

OBJECTIVETo investigate the effect of pancreatic duct stent internal versus external drainage with pancreaticojejunostomy on the early curative effect after pancreaticoduodenectomy (PD).

METHODSThe study was a prospective controlled trial. A total of 219 patients undergoing PD from January 2010 to March 2013 were randomly divided into external drainage group (n = 110) and internal drainage group (n = 109). The pancreatic duct stent was put in the jejunum during the operation in the internal drainage group, while that in the external drainage group was placed outside the body through the jejunum and abdominal wall. The intra-operative blood loss, operative duration, post-operative hospital stay, mortality rate, and the morbidity of pancreatic fistula as well as other complications were compared between the two groups.

RESULTSCompared with internal drainage group, pancreatic duct stent external drainage obviously reduced the morbidity of pancreatic fistula (13.6% vs. 22.6%), delayed gastric emptying (10.0% vs. 27.5%), abdominal infection (6.4% vs. 19.3%), intestinal obstruction (8.2% vs. 20.2%) along with the overall complications (24.5% vs. 41.3%) after PD (χ(2) = 5.735 8 to 11.047 7, P < 0.05), and shortened the healing duration of pancreatic fistula ((11.5 ± 2.9) d vs. (20.1 ± 5.7) d, t = 5.07, P < 0.01), while there was no significant difference in the intra-operative blood loss, operative duration, post-operative hospital stay and mortality rate, etc between the two groups (P > 0.05).

CONCLUSIONSPancreatic duct stent external drainage can effectively reduce the morbidity of pancreatic fistula and the overall complications after PD, which is safe and feasible. The method is worthy of popularization and application clinically.
