Blumgart anastomosis for pancreaticojejunostomy minimizes severe complications after pancreatic head resection

BACKGROUND: Leakage from the pancreaticojejunostomy is the major cause of septic complications after partial pancreaticoduodenectomy. This study evaluated a new transpancreatic U-suture technique (Blumgart anastomosis, BA), which aims to avoid shear forces during knot-tying. METHODS: Using a before-after study design, BA was compared with a modified Cattell-Warren anastomosis (CWA). Two patient cohorts (CWA, 90; BA, 92), which were similar with respect to primary diagnosis, age, sex and American Society of Anesthesiologists score, were compared retrospectively. Dependent variables were surgical and overall morbidity and mortality after partial pancreaticoduodenectomy. RESULTS: Duration of operation (354 versus 328 min for CWA versus BA; P = 0.002), pancreatic leakage rate (13 versus 4 per cent; P = 0.032), postoperative haemorrhage (11 versus 3 per cent; P = 0.040), total surgical complications (31 versus 15 per cent; P = 0.011), general complications (36 versus 17 per cent; P = 0.005) and length of intensive care unit stay (median 5.4 versus 2.8 days; P = 0.015) were significantly reduced after BA. These effects were not related merely to an improvement over time. CONCLUSION: BA appears to be a fast, simple and safe technique for pancreaticojejunostomy. It might reduce leakage rates and surgical complications after partial pancreaticoduodenectomy.
