基于胰腺全系膜切除理念的胰头癌整块切除原则

胰腺癌外科治疗现状胰腺癌是消化系统预后最差的恶性肿瘤之一,5年生存率<5%,中位生存时间<6个月[1]。近年来随着外科技术的进步、麻醉及围手术期管理水平的提高,胰头癌手术的安全性大大提高,围手术期死亡率<5%。胰头癌外科手术逐渐成为临床的常规手术,包括传统开腹手术以及具备时代特征的腹腔镜、达芬奇机器人手术蓬勃发展[1-3],胰头癌外科手术由强调安全性逐渐向追求根治切除转变,其中胰     

整块切除在胰头癌根治术中应用进展

正整块切除(en-bloc切除)概念的根本目的在于彻底切除肿瘤(R0切除),要求在行胰十二指肠切除时,强调采用"no-touch"隔离切除技术完整切除各组淋巴结,同时清扫胰腺周围、肠系膜上动脉(SMA)周围和腹膜后的软组织(淋巴、神经、胰腺系膜等),最后将肿瘤、各组淋巴结及周围软组织整块去除,突出手术切除的整体性,以降低术中肿瘤残余和肿瘤细胞脱落的风险~([1-4])。本文对整块切除在胰头癌根治术中的应用进行综述。     

胰腺全系膜切除在胰头癌行胰十二指肠切除术中的应用及意义

正胰腺癌早期诊断困难,手术切除率低,预后极差,五年生存率仅为6%[1]。是否接受根治性的R0切除是决定胰头癌病人远期预后的最重要因素[2]。然而,即使对于接受根治性胰十二指肠切除术的病人,肿瘤的局部复发仍是限制胰腺癌疗效的重要因素。对胰头癌根治性切除标本的临床病理学研究显示,至少有70%~80%的病人并未获得严格意义上的R0切除,尤其是胰腺环周切缘的阳性,使得这部分病人的生存期明显缩短[3]。如何减少由于不能     

胰腺全系膜切除理念争议及评价

近年来,胰腺系膜的概念被临床所关注,胰腺癌的R1切除也被认为是胰腺系膜切除不足。胰腺全系膜切除的理念随后被提出和应用。该方法安全且被认为可提高胰腺癌的R0切除率,但最终效果仍待进一步的研究证明。尽管胰腺系膜的概念和胰腺全系膜切除的方法、范围、技术、效果等均存在争议,但胰腺系膜涵盖了胰腺癌最关键的手术区域,胰腺全系膜切除有望改善胰腺癌病人预后,值得进一步的临床探索研究。     

区域性胰腺切除治疗胰头癌的临床实践和探索

目的：临床研究区域性胰腺切除治疗胰头癌的效果。方法：采用区域性胰腺切除（ＲＰ）治疗３９例，其中包括尖胰十二指肠切除的基础上扩大区域淋巴结廓清的Ｏ型ＲＰ２０例，同时联合切除受肿瘤侵犯的肠系膜上静脉门静脉（ＳＭＰＶ）的Ⅰ型１８例，和联合切除受侵的肠系膜上的动脉的Ⅱ型１例。结果：２０例发生了围手术期并发症（５１．３％），围手术期死亡率５．１％，获随访３６例（９２．３％），其中２１例已死亡的病例中，除２例     

三维可视化技术在胰头癌胰腺全系膜切除术中应用研究

目的 探讨三维可视化技术在胰头癌胰腺全系膜切除术中的应用价值。方法 回顾性分析2013年1月至2017年6月在上海交通大学医学院附属新华医院普外科行胰腺全系膜切除的105例胰头癌病人资料,采用三维可视化技术对胰头肿瘤的部位、大小、与周围血管的毗邻关系进行观察,完成术前可切除性的评估,共施行胰腺全系膜切除术105例。结果 平均手术时间239 min,平均术中出血409 mL。29例（27.6%）发生术后并发症,无围手术期死亡病例。74例标本三维空间切缘病理学检查达到R0切除,R0切除率为70.5%。结论 三维可视化技术在胰头癌全系膜切除术前规划中的应用,可以更好地指导胰头癌的精准手术,提高了术前评估的准确率与手术的R0切除率,降低手术并发症发生率。

Application and progress of medical imaging in total mesopancreas excision for pancreatic head carcinoma

Pancreatic head carcinoma (PHC) is one of the common gastrointestinal malignancies with a high morbidity and poor prognosis. At present, radical surgery is still the curative treatment for PHC. However, in clinical practice, the actual R0 resection rate, the local recurrence rate, and the prognosis of PHC are unsatisfactory. Therefore, the concept of total mesopancreas excision (TMpE) is proposed to achieve R0 resection. Although there have various controversies and discussions on the definition, the range of excision, and clinical prognosis of TMpE, the concept of TMpE can effectively increase the R0 resection rate, reduce the local recurrence rate, and improve the prognosis of PHC. Imaging is of importance in preoperative examination for PHC; however, traditional imaging assessment of PHC does not focus on mesopancreas. This review discusses the application of medical imaging in TMpE for PHC, to provide more accurate preoperative evaluation, range of excision, and more valuable postoperative follow-up evaluation for TMpE through imaging. It is believed that with further extensive research and exploratory application of TMpE for PHC, large-sample and multicenter studies will be realized, thus providing reliable evidence for imaging evaluation.     

Total mesopancreas excision is the better staging tool of the mesopancreas in pancreatic head carcinoma

Preoperative imaging staging based on tumor, node, metastasis classification cannot be effective to avoid R1 resection because only further improvements in imaging technologies will allow the precise assessment of perineural and lymphatic invasion and the occurrence of microscopic tumour deposits in the mesopancreas. However, waiting for further improvements in imaging technologies, total mesopancreas excision remains the only tool able to precisely assess mesopancreatic resection margin status, maximize the guarantee of radicality in cases of negative (R0) mesopancreatic resection margins, and stage the mesopancreas.     

腹腔镜下胰腺全系膜切除治疗胰头癌的临床疗效分析

目的探讨腹腔镜下胰腺全系膜切除治疗胰头癌的临床疗效。 方法回顾性分析2013年4月至2016年4月46例胰头癌患者资料,根据手术术式的差异分为腹腔镜组(25例)和开腹组(21例),腹腔镜组行腹腔镜下胰腺全系膜切除术,开腹组行开腹胰十二指肠切除术。采用SPSS 19.0统计学软件进行统计分析,术前和术后相关指标以均数±标准差表示,组间比较采用独立t检验;R0切除率、术后并发症发生率采用χ²检验,以P<0.05表示差异有统计学意义。 结果腹腔镜组患者的R0切除率为88.0%,开腹组患者为61.9%(P<0.05);与开腹组相比,腹腔镜组患者的手术时间显著增加,而术中出血量及术中输血量均显著减少(P<0.05);与开腹组相比,腹腔镜组患者的术后肛门排气时间、进食流质食物时间及住院时间均显著缩短(P<0.05);腹腔镜组患者术后并发症的发生率16.0%,开腹组42.9%,差异具有统计学意义(P<0.05)。 结论腹腔镜下胰腺全系膜切除治疗胰头癌的临床疗效较好,且安全性较高,值得在临床上推广应用。     

胰腺癌外科治疗新进展

胰腺癌的诊断和治疗问题仍极具挑战性。虽无前瞻性的研究结果报道,仍提倡对“可切除”及“可能切除”的胰腺癌患者进行新辅助治疗,以提高R0切除率。近年来针对腹膜后切缘问题不断有术式改进的报告,如动脉优先入路、提拉悬吊技术、钩突优先入路等,丰富了传统的切除方式。鉴于病理学对R0及R1切除判断标准的再评价,应重新审视R1切除对改善患者预后的价值和意义。在淋巴结清扫范围方面,基于若干临床随机对照研究结果,以日本胰腺学会淋巴结分组为基础,目前研究者们普遍认为应清扫至第二站淋巴结。由解剖学层面对胰腺系膜的探讨及临床应用有助于提高腹膜后切缘的阴性率。     

胰头癌根治性胰十二指肠切除术若干问题的思考

作者在为胰头癌施行根治性胰十二指肠切除术的过程中,依据实践,结合文献复习,针对目前的某些热点问题,提出应避免主动性姑息性胰十二指肠切除术.提倡淋巴结廓清至少应达二站淋巴结,建议将肝十二指肠韧带骨骼化清扫和腹膜后组织切除作为根治性胰十二指肠切除术的常规手术步骤,无论有无证据支持第13组淋巴结(胰头后淋巴结)已发生转移,均应对可切除胰头癌进行限制性腹膜后组织切除.显露肠系膜上动脉并辨清钩突下缘和左侧缘与动脉的关系,是保证钩突切除完整性的技术要点.术前评估血管成像等影像学资料,可提高主动性联合血管切除的手术比例.胰肠吻合方式的选择,手术者的经验非常重要,从自己熟悉和熟练的二三种方法中选择最适合患者的方式,作者更偏向于胰肠端侧双层套入吻合法.并认为能量外科技术平台(电外科工作站)应用应慎重,仍须积累更多的经验再做评价.

Abstract：

According our practice of raical pancreaticoduodenectomy for pancretic head carcinoma and combined with these reviews, we suggested the active and palliative pancreaticoduodenectomy should be aviod. Skeletonization of hepatoduodenal ligament and the retroperitoneal resection should be the routine procedure in pancreticoduodenectomy, and at least invovle two regional lymph nodes. In addition, regardless of the metastase of No 13 lymph node, ristricted retroperitoneal resection for resectable pancretic carcinoma was needed. Exposured the superior mesenteric artery and distinguished inferior of uncinate process of pancrease with the artery, were the key point of the uncinate process of pancrease resection. Preoperative evaluation of angiography and other images, the ratio of activeness and combination with vessel resection would be improved. The style of pancreaticojejunostomy could be selected by the experience of the operator, we are apt to the double-deck invaginated pancreaticojejunostomy. Additionally, utilization of the electronic surgical workstation, should be careful and also need to accumulate more experience.     

Duodenum-preserving total pancreatic head resection without segment resection of the duodenum for chronic pancreatitis

Purpose  The purpose of this study was to describe a duodenum-preserving total pancreatic head resection procedure without segment resection of the duodenum for the treatment of chronic pancreatitis with an enlarged pancreatic head. Materials and methods  Between January 1999 and December 2006, 35 patients with chronic pancreatitis were operated on by duodenum-preserving total pancreatic head resection procedure without segment resection of the duodenum. These patients were followed up to estimate the outcomes of the surgical procedure. Results  The mortality of the surgical procedure was 0. The overall morbidity was 17%. One patient developed pancreatic fistula, three patients developed bile leakage, and no patient developed duodenal fistula. Twenty-one patients who suffered abdominal pain in preoperative stage obtained complete pain relief, the mean European Organization for Research and Treatment of Cancer QLQ-C30 pain scale decreased from 59 ± 27 to 13 ± 21. In the postoperative stage, the endocrine function of the patients compared equally to the preoperative stage. Conclusion  The modified procedure obtains acceptable postoperative outcomes and benefits on extirpation of inflammatory lesions and avoidance of the anastomosis of the residual pancreatic head and the jejunum.     

Duodenum-preserving pancreatic head resection for pancreatic metastasis from renal cell carcinoma: a case report

Introduction We report a case of duodenum-preserving pancreatic head resection (DPPHR) for the treatment of pancreatic head metastasis from renal cell carcinoma (RCC). Case report The patient was a 59-year-old male with a medical history of RCC 18 years ago. Abdominal imaging studies revealed a hypervascular mass localized in the pancreatic head without distant metastasis or tumor invasion into the adjacent organs including the common bile duct and duodenum. Under the preoperative diagnosis of pancreatic metastasis from RCC, the tumor was completely resected by DPPHR. The pathological examination of the resected specimen confirmed the preoperative diagnosis. Conclusion As lymph node metastasis has been rarely reported in previous cases of pancreatic metastasis from RCC, DPPHR should be considered as a less invasive surgical option to provide a favorable postoperative quality of life (QOL).

Duodenum-preserving total pancreatic head resection for cystic neoplastic lesions in the head of the pancreas

Background/Purpose Cystic neoplastic lesions of the pancreas are now found with increasing frequency. Duodenumpreserving pancreatic head resection with segmental resection of the duodenum has been introduced for the surgical treatment of inflammatory and neoplastic lesions. We report the following data from 15 patients treated surgically for cystic neoplastic lesions of the pancreas head. Methods Duodenum-preserving total pancreatic head resection (DPPHRt) with segmental resection of the duodenum (SD) was performed in eight patients, five with intraductal papillary mucinous neoplasm (IPMN), two with mucinous cystic neoplasm (MCN), and one with cystic endocrine neoplasm (EN). In four patients, a subtotal pancreatic head resection was performed, but recurrence of the IPMN lesion was observed in two patients. Ten patients suffered cystadenoma, three patients had a borderline lesion, and two patients had an in-situ carcinoma. Results Eight patients had a DPPHRt with SD resection, two patients had a resection of the uncinate process including segmental resection of the inferior duodenal segment, and one patient had a duodenum-and spleen-preserving total pancreatectomy. In four patients a DPPHR with subtotal pancreatic head resection was carried out. Postoperative local complications occurred in eight patients: there was a recurrence of the IPMN lesion in the remnant pancreatic head in two patients; and there was intraabdominal bleeding in one patient, pancreatic fistula in one patient, and delay of gastric emptying in four patients. Seven patients showed signs of acute pancreatitis. Hospital mortality was 0%, and postoperative length of hospital stay was 10. 4 days (range, 8–18 days). Conclusions Duodenum-preserving total pancreatic head resection for IPMN, MCN, serous cystadenoma (SCA), and cystic EN lesions is a safe and beneficial surgical procedure. Segmental resection of the duodenum was applied for an oncologically complete resection. In regard to long-term outcome, the procedure is, additionally, a pancreatic cancer preventive strategy.
