Briefly, after the pancreatic transaction, a stent tube was inserted into the lumen of the pancreatic duct and ligated with it by a fast-absorbable suture. Another tip of the stent tube was introduced into the intestinal lumen at the jejunal limb, where a purse-string suture was made by another fast-absorbable suture to roughly fix the tube. The pancreaticojejunostomy was completed by ligating two fast-absorbable sutures to approximate the ductal end and the jejunal mucosa, and by adding a rough anastomosis between the pancreatic parenchyma and the seromuscular layer of the jejunum. The initial surgical results with this method were retrospectively compared with those of the 28 patients treated with conventional duct-to-mucosa anastomosis.RESULTS: The incidences of postoperative morbidity including pancreatic fistula were comparable between the two groups (new; 3%-17% vs conventional; 7%-14% according to the definitions). There was no mortality and re-admission. Late complications were also rarely seen.CONCLUSION: A pancreaticojejunostomy using an irradiated polyglactin 910 suture material and a temporary stent is easy to perform and is feasible even in cases with a narrow pancreatic duct and a normal soft pancreas.展开更多

No consensus exists regarding the optimal pancreaticojejunostomy reconstruction technique to reduce this complication. We aimed to perform a systematic review comparing two commonly used techniques of pancreaticojejunostomy reconstruction （duct-to-mucosa versus invagination）, by meta-analysis and assessment of evidence quality. Methods Databases searched including The Cochrane Library, Medline, PubMed, Embase, etc. Randomized controlled trials （RCTs） comparing duct-to-mucosa and invagination pancreaticojejunostomy were included. Outcomes of interest were pancreatic fistula rate, mortality, morbidity, reoperation and hospital stay. Pooled estimates were expressed as risk ratio （RR） or mean difference. Results From 321 identified abstracts, four RCTs （467 patients; duct-to-mucosa： 232; invagination： 235） were included. Pancreatic fistula rate （RR, 0.74; 95% confidence interval （C/）： 0.24-2.28; P=0.60）, mortality （RR, 1.18; 95% CI： 0.39- 3.54; P=0.77）, morbidity （RR, 0.91; 95% CI： 0.69-1.21; P=0.53）, reoperation （RR, 1.09; 95% CI： 0.54-2.22; P=-0.81） and hospital stay （mean difference, -1.78; 95% CI： -4.60-1.04; P=0.22） were similar between techniques. Conclusions Duct-to-mucosa and invagination pancreaticojejunostomy are comparable with regards to assessed parameters. High-quality, large-volume, multi-center RCTs with standard outcome definitions are required.展开更多
