应用大网膜衬垫技术预防腹腔镜胰十二指肠切除术后胰瘘及相关并发症研究

目的 探讨大网膜衬垫技术在降低腹腔镜胰十二指肠切除术（LPD）后胰瘘及相关并发症发生率的应用。方法 回顾性分析2018年1月至2021年12月复旦大学附属华东医院普外科实施的88例LPD病人的临床资料。采用倾向性评分匹配（PSM）法对网膜衬垫组（采用大网膜衬垫技术）和对照组（未采用大网膜衬垫技术）进行2∶1匹配,网膜衬垫组获得38例病人,对照组获得19例病人,比较匹配后两组相关临床指标。结果 网膜衬垫组在B、C级胰瘘发生率（10.5%vs. 26.3%）,术后迟发性出血（2.6%vs. 10.5%）以及术后感染率（0 vs. 21.1%）低于对照组（P<0.05）。单因素分析显示,BMI、血清清蛋白、大网膜衬垫技术以及术后第1天胰肠侧引流液淀粉酶与LPD术后胰瘘发生相关;多因素分析显示,BMI≥23、血清清蛋白<35 g/L和未应用网膜垫是LPD术后胰瘘发生的独立危险因素。结论 大网膜衬垫技术可有效减少LPD术后胰瘘、出血及其相关严重并发症的发生,提高围手术期安全性。

胰十二指肠切除术胰瘘的防治

近二十年来由于手术技术和围手术期处理的改善，胰十二指肠切除术的手术死亡率已明显下降，但术后并发症率仍很高。胰瘦是胰十二指肠切除术最严重和最常见的并发症。近年来其发生率仍在10％左右，发生后死亡率达50％[1]。主要是由于胰瘘可造成腹腔内严重感染和大出血。因此防止胰瘘的发生是降低术后死亡率的关键之一。胰十二指肠切除术残留胰腺的大小、质地，胰管的直径、以及胰液排出量与胰瘘的发生有明显的关系。残留胰腺质地柔软、胰液分泌率相对高而且通过未扩张胰管时易引起吻合口瘘，因此残胰可分为正常、柔软、脆弱而且胰管未扩张和…

胆胰分流消化道重建在胰十二指肠切除术中的应用

从1935年Whipple报道壶腹部肿瘤胰十二指肠切除后,胰十二指肠切除术(pancreaticoduodenectomy,PD)渐成为壶腹周围癌的标准治疗方法.近年来,由于手术熟练程度的改善、手术方法及围手术期管理等方面的改进,胰十二指肠切除术的病死率已明显地改善,但由于手术切除范围广泛、消化道重建等手术操作复杂,术后并发症仍有较高的发生率,其中胰瘘是其常见且严重的并发症,文献报道胰十二指肠切除术后胰瘘的发生率仍可达5%～10%,其中病死率甚至可达25%[1],其对患者的生存质量和预后都产生严重的影响.因此减少和预防胰瘘的发生仍是当前胰十二指肠切除术迫切需要解决的难题.

The analysis of diagnosis and treatment for pancreatic fistula after pancreaticoduodenectomy for 105 periampullary carcinoma cases

Aim: To investigate the ways in which to decrease the morbidity of pancreatic fistula after pancreaticoduodenectomy and corresponding therapy. Methods: Double-layered end-to-side duct-to-mucosa anastomosis was applied in 105 cases of pancreaticoduodenectomy and pancreaticoenteric reconstruction, postoperative pancreatic fistula cases were treated aggressively by early surgery, effective drainage and enteral nutrition. Results: Ten cases of pancreatic fistula occurred among 105 operative cases and required reoperation. The rest of the cases recovered uneventfully, except for five cases of in-hospital death. Conclusion: Aggressively early surgery, effective drainage, comprehensive treatment and continual improvement of operative technique are the key to dealing with postoperative pancreatic fistula.     

Predictive factors for complications after pancreaticoduodenectomy

BACKGROUND: Knowledge of the risk factors for complications following pancreaticoduodenectomy (PD) is sparse and there is not a consensus regarding the criteria to define the complications. The objective of this study was to determine the predictive risk factors for this surgery using the international study group definition. PATIENTS AND METHODS: Between October 1999 and September 2005, data from 295 consecutive patients who underwent a PD in the Eastern Hepatobiliary Surgery Hospital were recorded prospectively. Medical records and specific charts from surgical procedures, histopathology reports, and intensive care units were continually scrutinized. Multivariable logistic regression analyses were used to estimate relative risks and their 95% confidence intervals. RESULTS: Among 295 patients undergoing PD, 103 (34.9%) experienced at least one complication. Operations by low-volume surgeons (<50 PD surgeries across their lifetime) were followed by more abdominal complications (odds ratio [OR] 45.2). End-to-end pancreaticojejunostomy (PJ) resulted in more complications than end-to-side PJ (OR 2.7). Diabetes mellitus, increased estimated blood loss, and soft gland texture significantly increased the risks of abdominal complications. Systemic morbidity (OR 9.9) was the only independent predictive factor for mortality. CONCLUSION: High-volume surgeons and end-to-side PJ greatly reduce the risk of abdominal complications in patients undergoing PD. The higher abdominal complications rate in patients with soft gland texture was similar to those found in previous reports. Moreover, PD should be performed with considerable attention in patients with diabetes mellitus.     

Amylase level after pancreaticoduodenectomy in predicting postoperative pancreatic fistula

BackgroundIt is new clinical interest higher serum amylase level with pancreatitis after pancreaticoduodenectomy (PD) correlates with postoperative pancreatic fistula (POPF). Nevertheless, its evidence and study were scarce. We aimed to investigate correlation of serum amylase level immediate after PD and POPF occurrence.MethodsOf 163 patients who underwent PD at between January 2009 and December 2019, retrospective analysis was conducted to identify risk factors including serum amylase level immediate after PD for POPF occurrence.ResultsOverall incidence of POPF (25/163) was 15.3%. The patients occurred a POPF had significantly higher level of serum amylase on POD0 compared to in whom without a POPF (414 vs 253, p < 0.001). In univariate analysis, ASA classification, post pancreatectomy acute pancreatitis (POAP, serum amylase on POD0 >285IU/L) and Fistula Risk Grade were correlated with POPF occurrence. In multivariable analysis, Fistula risk grade and POAP were significantly associated with developing POPF.ConclusionIn patients with higher serum amylase (>285IU/L) on POD0 with higher fistula risk grade, comprehensive management to achieve mitigation of POPF is important.

Prognostic significance of pancreatic fistula and postoperative complications after pancreaticoduodenectomy in patients with pancreatic ductal adenocarcinoma

BackgroundThe influence of postoperative complications, specifically, pancreatic fistula (PF), on long-term oncologic outcome in patients with pancreatic ductal adenocarcinoma (PDAC) is unclear.MethodsProspectively collected data of patients who underwent pancreaticoduodenectomy (PD) for PDAC between 2008 and 2016 were retrospectively reviewed and analyzed. Deaths within 90 days were excluded. Median follow-up time was 22 months for the entire cohort (range 2–102 months). PF was graded as biochemical leak, grade B, or grade C according to the criteria of the International Study Group on Pancreatic Fistula. Postoperative complications were graded according to the Clavien-Dindo classification (CDC). Data on clinical and pathological characteristics as well as on recurrence and survival were collected.ResultsTwenty-nine of the 148 identified patients (19%) developed PF, of whom 17 (11.4%) had a PF grade B or C. 29 patients developed a postoperative complication CDC grade 3 or 4. The respective 3-year disease-free survival was 15.5% and 19.2% (P = 0.725), and the 5-year overall survival was 20% and 16% (P = 0.914) in patients with and without PF. On multivariate analysis, the use of adjuvant chemotherapy, lymph node involvement, surgical margin involvement, and tumor grade were associated with patient survival. PF and postoperative complications CDC grade 3 or 4 were not associated with decreased long-term survival, disease-free survival or local recurrence rate.ConclusionsWhile acknowledging the limited sample size, no association was seen between PF or postoperative complications and overall or disease-free survival in patients undergoing PD for PDAC.
