ABSTRACT
<p><b>OBJECTIVE</b>To evaluate wound healing after types of pancreaticojejunostomy.</p><p><b>METHODS</b>After resection of the pancreatic head, 38 domestic piglets were divided into two groups according to the types of anastomoses group I binding pancreaticojejunostomy, a new technique designed and advocated by professor Peng Shuyou; group II end-to-end pancreaticojejunal invagination. Anastomotic strength in vivo and histopathological findings were assessed on operative day and postoperative day 5 and 10.</p><p><b>RESULTS</b>Bursting pressure was 139.7 +/- 8.0, 178.7 +/- 9.7 and 268.8 +/- 12.8 mm Hg in group I on day 0, 5 and 10, whereas 67.3 +/- 7.9, 96.2 +/- 10.4 and 130.6 +/- 9.3 mm Hg in group II. The gain on day 0 to 5 and 5 to 10 was 27.9% and 50.5% in group I and 42.9% and 35.7% in group II, respectively. A significant difference was observed between group I and group II, and between 5 and 10 day after anastomoses (P < 0.01). Breaking strength was 4.5 +/- 0.4, 6.6 +/- 0.4 and 10.0 +/- 0.6 N in group I on day 0, 5 and 10 and 4.6 +/- 0.6, 5.8 +/- 0.5 and 7.1 +/- 0.6 N in group II. Although a similar value was shown in both types of anastomoses on day 0, a rapider gain was demonstrated on day 0 to 5 and 5 to 10 in group I (44.8% and 52.9%) than in group II (25.4% and 22.0%). A significant difference was found on day 5 and 10 between the two types of anastomoses (P < 0.05 and P < 0.01). Anastomotic site was well repaired by connective tissue and the cut surface of pancreatic stump was covered by mucosal epithelium in group I on day 10, but the cut surface was incompletely repaired by granulation tissue and no, regeneration of the epithelium was found in group II.</p><p><b>CONCLUSION</b>Anastomotic strength of binding pancreaticojejunostomy was stronger than end-to-end pancreaticojejunal invagination and the healing was better and rapid.</p>
