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%。     

A giant retention cyst of the pancreas (cystic dilatation of dorsal pancreatic duct) associated with pancreas divisum

We describe a rare case of pancreas divisum associated with a giant retention cyst (cystic dilatation of the dorsal pancreatic duct), presumably formed following obstruction of the minor papilla. The patient was treated by pancreatico(cysto)jejunostomy. A 50-year-old man was admitted with complaints of increasing upper abdominal distension and body weight loss. There was no previous history of pancreatitis, gallstones, drinking, or abdominal injury. An elastic-hard tumor-like resistance was palpable in the upper abdomen. Computed tomography and ultrasound (US) examinations revealed a giant cystic lesion expanding from the pancreas head to the tail. Endoscopic retrograde cholangiopancreatography findings showed a looping pancreatic duct which drained only the head and uncinate process of the pancreas to the main papilla. A US-guided puncture to the cystic lesion revealed that the lesion continued to the main pancreatic duct in the tail of pancreas. The lesion was connected to a small cystic lesion, which was located inside the minor papilla, and ended there. The amylase level in liquid aspirated from the cyst was 37 869 IU/l, and the result of cytological examination of the liquid showed class II. A pancreatico(cysto)jejunostomy was performed, with the diagnosis being pancreas divisum associated with a retention cyst following obstruction of the minor papilla. The histological findings of a specimen from the cyst wall revealed that the wall was a pancreatic duct covered with mildly inflammatory duct epithelium; there was no evidence of neoplasm. The patient is currently well, and a CT examination 2 years after the operation showed disappearance of the cyst and normal appearance of the whole pancreas.

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。     

胰十二指肠切除术后胰瘘的预防

胰十二指肠切除是治疗胰头及壶腹周围良、恶性疾病的一种复杂的手术方式。随着手术技术的改进和术后管理的提高,已经使胰腺切除术后死亡率减少到5%以下,然而术后并发症的发生率却改变很小,仍然在30%-40%范围。术后胰瘘依然是胰十二指肠切除术后最常见、最严重的并发症。捆绑式胰肠吻合作为一种安全、有效的吻合方式,能改变术后胰瘘的发生。胰管支撑引流可减少术后胰瘘的发生。生长抑素及其类似物的应用也可减少术后胰瘘的发生。     

Internal Pancreatic Stent Causing Irreversible Dilatation of Pancreatic Duct

A 28-year-old woman underwent a pylorus preserving Whipple procedure for pancreatic serous cystadenoma located on the head of the pancreas. During the operation, an internal stent (7F silastic catheter, 9 cm in length) was placed within the pancreatic duct in the area of pancreaticojejunal end-to-end Dunking type anastomosis to prevent development of fistula. The stent was positioned so that one third of its length would lie into the pancreatic duct, and it was anchored to the periductal pancreatic tissue with only one rapidly absorbable chromic suture. Leakage from the anastomosis was not observed, and she was discharged without any complaint. Early postoperative abdominal CT examination revealed that the stent was retained within the normal caliber pancreatic duct (Fig. 1a). Six months after the operation, she began to complain to epigastric pain triggered by the meals. The laboratory analysis was normal, particularly liver biochemical tests and serum amylase. The internal pancreatic stent within the dilated pancreatic duct was detected by an additional CT examination (Fig. 1b). The stent was removed endoscopically at the third attempt. The pain was resolved after its removal. Control CT examination which was taken at the 18th month after removal of the stent showed dilatation of the pancreatic duct (Fig. 2a). The patient remained free of any complaint, although regressed pancreatic duct dilatation has persisted over 4 years of follow-up (Fig. 2b).     

改良胰管空肠端侧吻合在胰十二指肠切除术中的应用

目的通过与其他吻合术式比较,探讨改良胰管空肠端侧吻合在胰十二指肠切除术中的应用价值。方法分析我院于2009年1月至2011年5月进行的203例因恶性肿瘤行胰十二指肠切除术的患者,其中A组86例,行改良胰管空肠端侧吻合;B组68例,行套入式胰肠端侧吻合;C组49例,行套入式胰肠端端吻合。分别比较胰肠吻合手术时间、术后胰瘘等并发症情况。结果 A、B、C三组胰肠吻合时间分别为(10.6±2.8)min、(19.9±3.6)min及(20.6±3.7)min,A组吻合时间显著低于其他两组(P<0.05)。术后胰瘘发生率A组最低,为1.1%(1/86),B组为4.4%(3/68),C组为6.1%(3/49)。结论胰管空肠端侧吻合操作简便省时,术后并发症发生率低,是胰十二指肠切除术中胰肠吻合的一种良好方法。     

捆绑式胰管对黏膜吻合术

目的 研究一种与捆绑式胰肠吻合术和捆绑式胰胃吻合术互补的术式--捆绑式胰管对黏膜吻合术的可行性.方法 (1)动物实验:对6只成年新西兰兔行胃肠造瘘术,两个造瘘口分别用导尿管、硅胶管、输液器管作为支撑管连接,导管两端分别置入胃腔与肠腔内,造瘘口荷包缝合,胃壁与肠壁浆膜层拉拢缝合周定.观察胃肠造瘘口处渗漏及愈合情况,显微镜下观察胃黏膜与空肠黏膜愈合情况.(2)临床实践:对7例患者施行捆绑式胰管对黏膜吻合术.手术方法包括:胰端的准备、肠侧的准备、胰断端与空肠对合固定的准备、吻合的实施、最后施行胰断端与空肠的对合固定.术后定期检测腹腔内引流管和血淀粉酶以及各种并发症的情况.胰漏按来源不同分为胰腺实质漏(胰创面漏)和吻合口漏两种.结果 动物实验结果显示愈合良好.临床全部病例均未出现吻合口漏,但有2例腹腔内引流液淀粉酶出现一过性增高,引流量均未超过50 ml/d,未影响患者康复,属于胰腺实质漏(胰腺创面漏).结论 捆绑式胰管对黏膜吻合术是一种简单安全的吻合方法,给外科医生提供了一种新的选择,以便在面对不同的患者时,能够灵活采用不同的方法去取得最理想的治疗效果.

Abstract：

Objective To study the feasibility of binding pancreatic duct to mucosa anastomosis (BDM)-a complementary procedure to both binding pancreaticojejunostomy and binding pancreaticogastrostomy. Methods (1) Animal experimental study: gastrostomy and jejunostomy were performed on six adult New Zealand rabbits. The gastrostomy and jejunostomy shared a same stent (rubber urethral catheter, silicone tube or plastic infusion tube). Both ends of the stent were placed in gastric and enteric cavity. Purse-string suture was performed around the stent before the jejunum and the stomach were brought together for fixation by few stitches. And to observe whether the purse-string suture around a plastic tube,rubber tube or silicon tube inserted into jejunum and/or stomach can prevent leaking out of the jejunal or gastric content to cause peritonitis. (2)Clinically 7 patients were performed with BDM anastomosis. The procedure was consisted of five steps: preparation of the pancreatic stump; preparation of the jejunum;preparation of the fixing sutures between the pancreatic stump and the jejunum; implementation of the anastomosis; lastly, fixation of the jejunum beside the pancreas stump. Post-operative periodic examination of the blood amylase and the amylase in the abdominal drainage. Pancreatic fistula was classified in to two categories: parenchymal fistula (pancreatic cut surface fistula) and anastomotic leakage. Results Animal experiment did not show any leakage around the plastic tube or silicon tube inserted into jejunum and(or) stomach. There was no anastomotic leak in all the patients. There was transient increase of amylase in two cases, but the volume of drainage did not exceed 50 ml/d and the recovery of the patients was not affected.Conclusions BDM is a simple, safe and easy procedure to perform. It provides to the surgeons with a new option in different situations to achieve the most ideal surgical result.     

胰十二指肠切除术中两种胰肠吻合方式疗效比较

目的 比较胰十二指肠切除术中采用胰肠套入吻合与胰管-空肠黏膜对黏膜吻合术后胰漏发生率、住院时间和费用的差异。方法 回顾2009年3月至2013年5月126例接受胰十二指肠切除术治疗病例,采用胰肠套入吻合67例,胰管-空肠黏膜对黏膜吻合59例。分析两种胰肠重建方式术后胰漏发生率及严重程度的差异,同时对两组平均住院时间及费用进行比较分析。结果 套入式胰肠重建组术后胰漏发生率为31.34%（21/67）,黏膜对黏膜胰肠重建组为13.56%（8/59）;两组术后胰漏严重程度（A、B、C级）情况分别为10.45%（7/67）,14.93%（10/67）,5.97%（4/67）和8.47%（5/59）,3.39%（2/59）,1.69%（1/59）。两组平均住院时间为（24.15 d vs 16.86 d）,费用分别为（49 882.73元 vs 38 047.80元）。两组患者术后胰漏发生率和严重程度B级所占比例、平均住院时间和费用差异均有统计学意义（P均＜0.05）。结论 采用胰管-空肠黏膜对黏膜吻合的胰肠重建方式术后胰漏发生率和严重程度（B级）、平均住院时间和费用明显低于采用胰肠套入吻合,该法可能更有利于患者术后恢复。
