ABSTRACT
OBJECTIVE: To investigate the clinical value of pancreaticogastrostomy(PG) in the treatment ofpancreatojejunostomy stricture(PJS) after pancreaticoduodenectomy(PD).METHODS: The clinical data of 3 patients withPJS who failed the endoscopic treatment underwent PG followed by resection of pancreatojejunostomy(PJ) from May2010 to December 2017 in Department of General Surgery,Xinhua Hospital,Shanghai Jiaotong University School ofMedicine were analyzed retrospectively. After the pancreatointestinal anastomosis was explored and resected, thedigestive tract of the remnant pancreas was reconstructed by using the single-layer bundle pancreaticogastric mucosaanastomosis. The intraoperative and postoperative conditions were observed.RESULTS: The median time of presentationwas 72,37 and 21 months. Three cases of operation were completed successfully. The operation time was 137, 210, 120 min,and blood loss was 210, 350, 180 m L. No pancreatic fistula,surgical bleeding and other serve complicationoccurred postoperatively. All the 3 patients experienced resolution of symptoms without recurrent acute pancreatitis afterPG during the follow-up of 23, 58 and 15 months.CONCLUSION: PG especially duct-to-mucosa PG followed byresection of PJ could be used in the PJS patients who failed the endoscopic treatment.
ABSTRACT
<p><b>BACKGROUND</b>Choledochal cyst is rare in western countries. The relatively high incidence of coexistent hepatobiliary disease increases the difficulty of the surgical management of choledochal cyst. Here we analyze the diagnosis and treatment of congenital bile duct cyst in 122 Chinese adults.</p><p><b>METHODS</b>The clinical data of 122 patients with congenital choledochal cysts admitted from 1981 to 2006 were analyzed.</p><p><b>RESULTS</b>Clinical symptoms in most cases were nonspecific, resulting in delayed diagnosis. Sixty-one patients (50%) had coexistent pancreatobiliary disease. Among the 122 patients, 119 patients underwent ultrasonic examination; ERCP/MRCP was performed in 63 cases and CT in 102 cases. Abnormal pancreatobiliary duct junction was found in 48 patients. Sixteen patients had malignant lesions in the bile duct, arising in 11 of them from incomplete choledochal cyst that underwent various operations including cystenterostomy or cystojejunostomy. There was significant difference between the patients who underwent incomplete cyst resection and complete cyst resection in malignancy rate of bile duct (Chi square test, P = 0.000; odds ratio, 7.800; 95% confidence interval, 2.450 to 24.836).</p><p><b>CONCLUSIONS</b>ERCP, CT and MRCP had proved their great values in the classification of the disease. Cyst excision with Roux-en-Y hepaticojejunostomy is recommended as the treatment of choice for patients with type I or type IV cysts. For type V cyst (Caroli's disease) with recurrent cholangitis, liver transplantation should be considered.</p>

<p><b>OBJECTIVE</b>To evaluate wound healing after pancreaticojejunostomy of three anastomotic methods.</p><p><b>METHODS</b>Fifty-four domestic piglets were divided into three groups according to the types of anastomoses: group of end-to-end pancreaticojejunal invagination (EE group), group of binding pancreaticojejunostomy (BP group) and group of inkwell pancreaticojejunostomy (IP group). Bursting pressure, breaking strength and histopathological findings of anastomosis were assessed on operative day and on the 5th and 10th day after operation.</p><p><b>RESULTS</b>Bursting pressure was (67+/-8) mm Hg, (96+/-11) mm Hg and (131+/-9) mm Hg in EE group on day 0, 5 and 10; and (140+/-8) mm Hg, (179+/-10) mm Hg and (269+/-13) mm Hg in BP group; and (102+/-10) mm Hg, (171+/-18) mm Hg and (254+/-24) mm Hg in IP group. Compare to EE group, bursting pressure of BP group and IP group were all increased with significant differences (P<0.05). Another significant difference was observed between BP group and IP group after anastomoses on operative day. Breaking strength was (4.6+/-0.6) N, (5.8+/-0.5) N and (7.1+/-0.6) N in EE group on 0 d, 5 d and 10 d; and (4.5+/-0.4) N, (6.6+/-0.4) N and (10.0+/-0.6) N in BP group; and (4.6+/-0.3) N, (6.5+/-0.4) N and (9.1+/-0.9) N in IP group. A similar value of anastomoses was shown in BP group and IP group on day 0, day 5 and day 10, but significant increase was demonstrated compared to EE group on day 5 and 10. Anastomotic site was well repaired by connective tissue and the cut surface of pancreatic stump was covered by mucosal epithelium in BP group and IP group on day 10, but the cut surface was incompletely repaired by granulation tissue and no regeneration of the epithelium was found in EE group.</p><p><b>CONCLUSIONS</b>Wound healing of binding pancreaticojejunostomy and inkwell pancreaticojejunostomy is more rapid and better than end-to-end pancreaticojejunal invagination, but breaking strength of inkwell pancreaticojejunostomy is weaker than binding pancreaticojejunostomy.</p>
