目的 探讨心导管术后的外周血管并发症的发生原因、临床表现和处理方法。方法 对心导管术后有外周血管并发症的患者的临床资料进行分析。结果 本院1996年1月-2000年1月共完成各类心导管术508例,发现外周血管并发症28例（5.5%),其中局部血肿22例,假性动脉瘤1例,动脉静瘘1例,静脉血栓形成2例,动脉血栓形成1例,股神经功能障碍1例。所有并发症经内科保守治疗后均好转。结论 心导管术后外周血管并发症不可忽视。但只要及时处理。绝大多数预后良好。     

胃-肠瘘引起腹泻的临床分析(附5例报告)

目的 探讨胃－肠瘘引起腹泻的临床特点。方法 从1988年1月－1998年12月我院消化内科住院患者2885例中筛选出以腹泻为主要临床表现的所有病例,其中胃－肠瘘为病因的5例,总结分析其各方面的临床资料。结果 5例患者均有毕II式胃大部切除术病史,腹泻特点均为吸收不良性腹泻表现,予去麦胶饮食及抗感染治疗,疗效欠佳。就诊时均有明显的低蛋白血症。均能通过消化道钡餐造影明确诊断,胃镜诊断率仅40％。二次手术治疗,症状均得到缓解。结论 在诊治腹泻患者,特别是有胃大部切除病史的患者时,要考虑到胃－肠瘘的可能。     

The impact of location and patency of the arteriovenous fistula on quality of life of kidney transplant recipients

BackgroundArteriovenous fistulae (AVFs) may remain patent after kidney transplantation (KTx), contributing to maladaptive cardiac remodeling. The flow in AVFs is associated with the diameter of its vessels and thus with the AVF location. The main objective of this study is to assess the influence of AVF location and its patency on the self-reported quality of life (QOL) of kidney transplant recipients (KTRs) with past history of hemodialysis.MethodsTo gain clinical data, during a scheduled visit, 353 KTRs were asked to fill out an anonymous questionnaire. From this group, 284 respondents were found eligible for analysis. The outcome was defined as prevalence of symptoms and health status, measured with the Left Ventricular Dysfunction-36 (LVD-36) Questionnaire in symptomatic patients.ResultsThe hemodialysis patients (n = 243) were divided into two groups according to AVF location, i.e., DAVF – distally located AVF – (n = 174) and PAVF – proximally located AVF – (n = 69). The proportion of patients with heart failure (HF) was higher in PAVF group (24% vs. 12%, p = 0.0482). In the multivariable regression, PAVF, serum creatinine levels, and the presence of HF or coronary artery disease (CAD) remained independent predictors of lower functional capacity. Among patients with heart disease, the presence of active AVF was independently associated with worse functional outcome (higher LVD-36 scores).ConclusionsThe influence of persistent PAVF in KTRs seems to be unfavorable, especially when coexisting with CAD or HF.

Duodenal complications in necrotizing pancreatitis: Challenges of an overlooked complication

BackgroundDuodenal complications of necrotizing pancreatitis (NP) are challenging and understudied. We sought to characterize the demographics and clinical course of NP patients with duodenal complications.MethodsSingle institution retrospective review of 687 NP patients treated from 2005 to 2018.ResultsDuodenal complications developed in 40 (6%) patients including fistula in 11 (2%) and stricture in 29 (4%) patients. Patients with duodenal complications had increased computed tomography severity index (CTSI), degree of glandular necrosis, organ failure, infected necrosis, and disease duration. Mortality from NP was increased in patients with duodenal fistula (36%) compared to patients with duodenal stricture (7%) and patients without duodenal complications (9%). Surgical management of duodenal complications was required in 9/11 (82%) patients with fistula and 17/29 (59%) patients with stricture.ConclusionsDuodenal complications occurred in 6% of necrotizing pancreatitis patients. Sixty five percent of patients with duodenal complications required surgical correction. Duodenal fistula was associated with increased mortality.     

Duodenopancreatectomía cefálica y tutorización externa del conducto de Wirsung. Resultados de una serie de 80 casos consecutivos

IntroductionThere is controversy regarding the ideal pancreaticojejunostomy technique after pancreaticoduodenectomy. Many authors consider the external Wirsung stenting technique to be associated with a low incidence of fistula, morbidity and mortality. We analyse our experience with this technique.Patients and methodsA retrospective analysis of the morbidity and mortality of a series of 80 consecutive patients who had been treated surgically over a 6.5-year period for pancreatic head or periampullary tumors, performing pancreaticoduodenectomy and pancreaticojejunostomy with external Wirsung duct stenting.ResultsMean patient age was 68.3 ± 9 years, and the resectability rate was 78%. The texture of the pancreas was soft in 51.2% of patients and hard in 48.8%. Pylorus-preserving resection was performed in 43.8%. Adenocarcinoma was the most frequent tumor (68.8%), and R0 was confirmed in 70% of patients. Biochemical fistula was observed in 11.2%, pancreatic fistula grade B in 12.5% and C in 2.5%, whereas the abdominal reoperation rate was 10%. Median postoperative hospital stay was 16 days, and postoperative and 90-day mortality was 2.5%. Delayed gastric emptying was observed in 36.3% of patients, de novo diabetes in 12.5%, and exocrine insufficiency in 3. Patient survival rates after 1, 3 and 5 years were 80.2, 53.6 and 19.2%, respectively.ConclusionsAlthough our low rates of postoperative complications and mortality using external Wirsung duct stenting coincides with other more numerous recent series, it is necessary to perform a comparative analysis with other techniques, including more cases, to choose the best reconstruction technique after pancreaticoduodenectomy.     

腹腔镜胰腺外科手术缝合技术与缝合材料选择中国专家共识（2021版）

正胰十二指肠切除术(pancreaticoduodenectomy,PD)及胰体尾切除术(distal pancreatectomy, DP)作为治疗壶腹周围及胰体尾肿瘤的经典术式,具有手术难度大、技术要求高及术后并发症多等特点,是腹部外科极具代表性及挑战性的术式之一。随着手术理念、技术及缝合材料的更新、进步与优化,PD术后围手术期死亡率已降至3%以下,但术后并发症特别是胰瘘的发生率仍高达10%～30%。
