To compare the outcomes of pancreaticojejunostomy and pancreaticogastrostomy reconstruction after pancreaticoduodenectomy: A prospective observational study

BackgroundWe have been in constant search of novel innovations to decrease the high morbidity after Pancreaticoduodenectomy (PD). Pancreaticojejunostomy (PJ) and pancreaticogastrostomy (PG) are the two different methods of reconstruction after PD. However, the existing data is ambiguous in supporting either of them as the preferred technique of reconstruction.MethodsThis was a single-center prospective observational study that included 64 patients who underwent PD over two years. We compared PG with PJ as a method of reconstruction after PD. The primary objective was to assess whether PG decreases the rate of postoperative pancreatic fistula (POPF) rates or not. Secondary objectives comprised analysis of perioperative outcomes, 30-day and 90-day mortality.ResultsPancreatic fistula was significantly lower in PG as compared to the PJ group (24% vs. 47%) with a p-value of 0.027. The incidence of clinically pertinent (grade B) fistula was only 3% in the PG group and 32% in the PJ group. PG group had a higher incidence of post pancreatectomy hemorrhage (PPH) and delayed gastric emptying (DGE). No statistically significant difference was seen between either group need for blood transfusion, re-exploration, re-admissions, ICU stay, or length of hospital stay, and 30-day and 90-day mortality. Pancreatic texture and high BMI were independent predictors for pancreatic fistula.ConclusionPG when compared to PJ for reconstruction after PD, decreases the rate of POPF significantly; however, it is associated with an elevated risk of DGE and PPH. There was no difference in 30-day and 90-day mortality between both the treatment groups.     

胰腺-空肠端端套入式间断U型缝合法吻合在胰腺外科中的应用

目的:探讨胰腺-空肠端端套入式间断U型缝合法吻合在胰腺外科应用的临床价值。方法:回顾性分析我院自2001年1月到2006年4月间施行的胰头十二指肠切除术83例。比较不同胰肠吻合方法对胰瘘发生的影响。结果:胰瘘总发生率为27%(22/83)。胰肠端端套入式间断U型缝合法吻合术后恢复良好,无胰瘘发生。端端吻合的胰瘘发生率为40%(10/25);端侧吻合的胰瘘发生率为27%(12/44)。比较各种吻合方式,端端套入式间断U型缝合法吻合的胰瘘发生率显著低于端端吻合(P<0.01)和端侧吻合(P<0.05),而端端吻合和端侧吻合之间胰瘘发生率无明显差异(P>0.05)。结论:胰腺-空肠端端套入式间断U型缝合法吻合降低手术所致胰肠吻合口瘘的发生率,效果满意。但因临床例数较少,其安全可靠性、实用合理性还有待进一步观察、证实。     

改良胰管空肠黏膜端侧吻合胰十二指肠切除术临床效果研究

目的探讨改良胰管空肠黏膜端侧吻合的胰十二指肠切除术临床效果。方法回顾性分析2016年1月至2019年3月62例行胰十二指肠切除术(PD)患者临床资料,其中30例行改良胰管空肠黏膜端侧吻合术(改良组),32例行传统胰管空肠黏膜端侧吻合术(传统组)。选用SPSS 20.00统计学软件进行数据分析,围术期相关指标和术后第1、3、5、7、9 d的腹腔引流液淀粉酶水平用(±s)表示,采用独立t检验;并发症发生率采用χ^2检验,P<0.05差异有统计学意义。结果改良组出血量明显小于传统组(P<0.05),其余相关围术期指标差异均无统计学意义(P>0.05);改良组术后发生1例胰瘘明显小于传统组9例(P<0.05),其中改良组B级胰瘘发生率明显小于传统组(P<0.05),生化瘘、C级胰瘘发生率、淋巴瘘、胃排空发生率比较差异均无统计学意义(P>0.05);两组患者腹腔引流液淀粉酶含量在术后第1、3、5、7、9 d的检测期间内,传统组腹腔引流液淀粉酶含量小于改良组(P<0.05)。结论改良胰管空肠黏膜端侧吻合术相比于传统胰管空肠黏膜端侧吻合术在PD中能有效降低胰瘘的发生率,具有一定的临床推广价值。     

Considerations on pancreatic exocrine function after pancreaticoduodenectomy

The pancreaticoduodenectomy (PD) procedure may lead to pancreatic exocrine and endocrine insufficiency. There are several types of reconstruction for this kind of operation. Pancreaticogastrostomy (PG) was introduced to reduce the rate of postoperative pancreatic fistula. Although some randomized control trials have shown no differences regarding pancreatic leakage between PG and pancreaticojejunostomy (PJ), recently some reports reveal benefits from the PG over the PJ. Some surgeons concern about the performing of the PG and inactivation of pancreatic enzymes being in contact with the gastric juice, and the detrimental results over the exocrine pancreatic function. The pancreatic exocrine function can be measured with direct and indirect tests. Direct tests have the highest sensitivity and specificity for detection of exocrine insufficiency but require tube placement. Among the tubeless indirect tests, the van de Kamer stool fat analysis remains the standard to diagnose fat malabsorption. The patient compliance and time consuming makes it not so suitable for its clinical use. Fecal immunoreactive elastase test is employed for screening of exocrine insufficiency, is not cumbersome, and has been used to study pancreatic function after resection. We analyze the FE1 levels in our patients after the PD with two types of reconstruction, PG and PJ, and we discuss some considerations about the pancreaticointestinal drainage method after pancreaticoduodenectomy.     

贯穿缝合式胰肠（端侧）吻合术的临床研究与应用：附视频

目的研究一种安全可靠、简单通用的全新的胰腺吻合方法——贯穿缝合式胰肠端侧吻合术（PPJ）。方法总结泰兴市人民医院普外科2002年5月至2012年6月间47例应用PPJ行胰肠吻合（端端吻合6例,端侧吻合41例）的临床经验和手术方法。设计理念是手术时把胰腺切断看作是一个实质性器官（而非空腔器官）,用胰腺切断全层（而非切缘）与空肠进行吻合。一针贯穿缝合胰腺切断全层和空肠后、前壁全层,间断缝合6～8针同时完成胰腺切面与空肠前、后壁的吻合。主胰管内放置短的支架管,端侧吻合时对应的空肠壁全层切开。结果 PPJ的平均手术时间12（8～18）min。术后胰瘘（POPF）发生率29.8%（14/47）,其中A级胰瘘21.3%（10/47）,B级胰瘘8.5%（4/47）。无胰肠吻合口出血,无再次开腹手术和死亡病例。术后门诊随防34例,3个月后CT或MRI检查胰管未见明显扩张。结论贯穿缝合式胰肠端侧吻合术操作简单、吻合可靠,可适用于所有的胰腺切断,易于推广应用。     

胰十二指肠切除术中放置与不放置胰管支撑管的比较

目的评价不同胰肠吻合方式在胰十二指肠切除术中的临床疗效,探讨不放置胰管支撑管的胰肠吻合的适用性。方法我院自2012年1月~2015年12月收治的87例可行胰十二指肠切除术患者,按随机分配方式分为胰管-空肠黏膜对黏膜端侧吻合+胰管支撑管外引流组(A组,43例)和胰腺-空肠端侧吻合不放置胰管支撑管组(B组,44例),比较两种不同胰肠吻合方式行胰肠吻合术的时间及术后住院时间、术后并发症的发生率。结果术中未放入胰管支撑管组的胰肠吻合时间(平均15.4min)明显小于术中放入胰管支撑管组(平均21.1min),差异有统计学意义(t=7.137,P0.05)。B组患者术后住院时间小于A组(t=2.408,P0.05,差异有统计学意义)。两组患者术后胰漏、腹腔出血、腹腔感染、胃潴留,差异无统计学意义(χ~2=0.181,0.322,0.603,0.001;P0.05)。结论胰十二指肠切除术不放置胰管支撑管可减少手术时间,降低术后住院天数,且术后并发症的发生率无显著差异,是安全可靠的。

胰十二指肠切除术后不同胰肠吻合方式的效果与评价

目的比较胰十二指肠切除术后三种不同胰肠吻合方式的胰肠吻合口瘘发生率,探讨实施不同吻合方式的适用条件及其合理性。方法回顾性分析92例胰十二指肠切除术患者的临床资料。按吻合方式不同分为捆绑式胰肠吻合组(A组)、胰管对空肠粘膜端侧吻合组(B组)和套入式端侧吻合组(C组),观察其术后胰瘘的发生率。结果胰肠吻合口瘘的发生率为:A组1例(1/41,2.44%);B组无胰肠吻合口瘘发生;C组3例(3/19,15.79%)。A、B两组间胰肠吻合口瘘发生率无统计学差异(P>0.05);C组胰肠吻合口瘘发生率显著高于A、B两组,差异有统计学意义(P<0.05)。结论胰管对空肠粘膜吻合法和捆绑式吻合法均为较安全的胰肠吻合方法。在条件许可下,胰管对粘膜吻合法应作为胰十二指肠切除术首选的胰肠吻合方法。
