保留幽门的和标准的胰十二指肠切除术后胃排空延迟的对照研究

目的 探讨保留幽门的胰十二指肠切除术与标准的胰十二指肠切除术术后胃排空延迟的临床特点及防治方法.方法 回顾性分析哈尔滨医科大学附属第一医院胰胆外科2012年1月-2016年7月行标准的胰十二指肠切除术的401例患者的临床资料,其中行保留幽门的胰十二指肠切除术患者35例(8.7％),行标准的胰十二指肠切除术患者366例(91.3％),采用独立样本均数t检验x2检验或Fisher确切概率法、Mann-Whitney Test秩和检验等统计学方法比较保留幽门的胰十二指肠切除术组与标准的胰十二指肠切除术组术后主要并发症的发生情况以及胃排空延迟的转归情况.结果 与标准的胰十二指肠切除术组相比,保留幽门的胰十二指肠切除术组胃排空延迟的发病率(22.9％)显著高于标准的胰十二指肠切除术组(10.9％),P=0.038,其余主要并发症发生率差异无统计学意义(P≥0.05).保留幽门的胰十二指肠切除术组与标准的胰十二指肠切除术组发生胃排空延迟的严重程度(分级比较)相同(P≥0.05),但保留幽门的胰十二指肠切除术组胃排空延迟的平均恢复时间(12.13±3.09)d明显短于标准的胰十二指肠切除术组的(17.28 ±9.63) d(P=O.009).结论 保留幽门的胰十二指肠切除术增加术后发生胃排空延迟的风险,但不增加胃排空延迟的严重程度,相对于标准的胰十二指肠切除术术后胃排空延迟较易恢复,为保留幽门的胰十二指肠切除术患者围手术期管理提供依据.

Case-control study of delayed gastric emptying for patients underwent pylorus-preserving pancreaticoduodenectomy and standard Whipple procedure

Objective To study the delayed gastric emptying for patients underwent pylorus-preserving pancreaticoduodenectomy and standard Whipple procedure.Methods Clinical data of 401 consecutive patients who underwent standard Whipple procedure/pylorus-preserving pancreaticoduodenectomy between January 2012 and July 2016 in the First Affiliated Hospital of Harbin Medical University were retrospectively collected and analyzed.Using the independent-samples t test,x2 test or Fisher's exact test,Mann-Whitney test and other statistical methods to compare the postoperative complications between pylorus-preserving pancreaticoduodenectomy and standard Whipple procedure group.Results Compare with standard Whipple procedure group,delayed gastric emptying after pylorus-preserving pancreaticoduodenectomy occurred in 8 of 35 patients (22.9％),obviously higher than it after standard Whipple procedure occurred in 40 of 366 patients (10.9％) (P =0.038).Other postoperative complications were not significantly different (P ≥ 0.05).Each level of delayed gastric emptying after pyloruspreserving pancreaticoduodenectomy and standard Whipple procedure were not significantly different (P ≥ 0.05),but the average recovery time of delayed gastric emptying after pylorus-preserving pancreaticoduodenectomy (12.13 ± 3.09) d was obviously shorter than it after standard Whipple procedure (17.28 ± 9.63) d (P =0.009).Conclusions Pylorus-preserving pancreaticoduodenectomy increases the risk of delayed gastric emptying,but it does not increase severity delayed gastric emnptying by each level.The recovery time of delayed gastric after pyloruspreserving pancreaticoduodenectomy is shorter.
