慢性胰腺炎的外科治疗

目的 改善慢性胰腺炎的外科治疗效果。方法 回顾性分析我院外科1983－2000年收治的34例慢性胰腺炎病人的临床资料，并将其分为慢性钙化性胰腺炎及慢性梗阻性胰腺炎两组。结果 男性23例（68％），女性11例（32％），平均年龄52.89岁。嗜酒者23例（67.65%），合并胆石症者13例（38.24%），继往有急性胰腺炎发作者11例（32.35%）。主诉腹痛者28例（82.35%），合并黄疸者17例（50％），慢性钙化性胰腺炎与慢性梗阻性胰腺炎在某些临床表现间存在显著性差异，提示二者可能存在不同的发病机制。34 病人分别采用9种不同的手术方式，无围手术期死亡。Puestow手术及胰十二指肠切除可有效地缓解疼痛，并可改善胰外分泌功能，对胰内分泌的影响不大。Puestow手术并行胆肠吻合适于合并胆道狭窄的慢性胰腺炎病人，而仅行胆道引流效果不佳。结论 慢性胰腺炎的外科治疗应采用个体化原则，如合并胰管扩张可行Puestow引流手术，胰头炎性包块病人应行切除手术。     

慢性胰腺炎的分型与术式选择

目的 探讨慢性胰腺炎的分型与术式选择及其外科治疗效果。方法 回顾性分析我院外科1983-2004年收治的54例慢性胰腺炎患者的临床资料,并将其分为慢性钙化性胰腺炎及慢性梗阻性胰腺炎两组。结果男性41例(76％),女性13例(24％),平均年龄53．7岁。嗜酒者25例(46％),合并胆石症者21例(39％),原因不明特发性者2例(4％),既往有急性胰腺炎发作者18例(33％)。主诉腹痛者38例(70％),合并黄疸者27例(50％)。慢性钙化性胰腺炎与慢性梗阻性胰腺炎在某些临床表现问存在显著性差异,后者临床表现更趋复杂多样。34例患者分别采用9种不同的手术方式,无围手术期死亡。Puestow手术及胰十二指肠切除可有效地缓解疼痛,并可改善胰外分泌功能,对胰内分泌的影响不大。Puestow手术并行胆肠吻合适于合并胆道狭窄的慢性胰腺炎患者;胰头肿块型胰腺炎以黄疸为主要表现,应行胰十二指肠切除等切除术式,仅行胆道引流减黄效果良好,但胰头病变的演变尚待进一步观察。结论慢性梗阻性胰腺炎临床表现复杂,外科治疗应采用个体化原则。     

Groove pancreatitis masquerading as pancreatic carcinoma.

The clinicopathologic and radiologic features of groove pancreatitis masquerading as pancreatic carcinoma in eight Japanese patients were reviewed. All patients were men with a mean age of 58 years. Three patients complained of abdominal pain whereas others had jaundice. The jaundice fluctuated in one patient. Four patients had several episodes of pancreatitis, and four patients were alcoholics. Radiologically, a duodenal stricture was evident in five patients, biliary stenosis in six, pancreatic duct stenosis in four, and a mass in the pancreatic head in six. The biliary stenosis was characterized by smooth tapering, which improved after biliary drainage in three cases. Of the four patients who underwent angiography, two showed an encasement of vessels, one a hypervascular mass, and the other no abnormality. All patients underwent a pancreatoduodenectomy for suspected pancreatic carcinoma. However, the histopathologic diagnosis was chronic pancreatitis confined to the groove between the distal common bile duct, duodenum, and pancreas. The duodenum showed scarring and hyperplasia of the Brunner's gland. The biliary stenosis was produced by fibrosis and chronic inflammation around the distal common bile duct. Groove pancreatitis presents various clinical features, such as biliary obstruction, duodenal stenosis, and pancreatic mass, and often masquerades as pancreatic head carcinoma. This condition should be kept in mind when making a diagnosis of pancreatic head carcinoma to avoid an unnecessary radical operation.     

24例胆总管末端良性狭窄的诊治体会

目的探讨胆总管末端良性狭窄的病因和诊断与治疗。方法回顾性总结我院1986年以来收治的24例胆总管末端良性狭窄的诊治资料。胆囊切除术后10例，胆囊切除、胆道探查术后7例，胆源性胰腺炎术后2例，慢性胰腺炎5例。作0ddi括约肌切开成形术11例，其中加作壶腹间隔切开成形术2例，胆肠内引流术9例，内窥镜下括约肌切开术(EST)2例，胰十二指肠切除术2例。结果术后并发十二指肠漏1例，胰漏2例，胆漏、胰漏1例。治愈23例，死亡1例。经1～15年随访20例。偶发胆管炎3例，频发较重胆管炎1例，其余效果满意。结论对有胆道手术史和慢性胰腺炎病人出现反复上腹或右上腹疼痛、黄疸等症状，应考虑有胆总管末端良性狭窄，影像学检查和内镜检查结合手术探查，必要时行术中活检是主要诊断手段。应根据狭窄的类型和程度选择合适的手术方式。     

慢性胰腺炎胰,胆管梗阻的处理：附6例报告

在３７例慢性胰腺炎病人中，８例合并胆道梗阻（２２％），４例合并主胰管梗阻（１１％）；６列同时或异时合并胰、胆管梗阻（１９％）。其中１例在发现胰管扩张１年后，出现胆管梗阻；２例同时发现胰、胆管梗阻。３例因黄疸在外院先行胆道手术，术后腹痛持续，影像检查证实尚伴有胰管梗阻，而再次行胰管减压手术。未合并胆石和（或）胆管炎的单纯胆道梗阻一般不引起严重的腹痛。对腹痛症状较重，而又无胆管结石的慢性胰腺炎病人应特别警惕是否同时合并胰管梗阻。     

Surgical treatment of chronic pancreatic cholangiopathy

In a consecutive surgical series of 70 patients with chronic calcifying pancreatitis, 18 presented with fixed stenosis of the terminal common bile duct. Nine patients presented with jaundice and two had a palpable gallbladder. The most relevant laboratory datum in the series was a persistently high serum alkaline phosphatase level. Long tapering of the terminal common bile duct was the characteristic radiological sign in 45 of our patients. In five of the 18 cases compression of the terminal bile duct was due to cephalic pseudocysts. Hepaticojejunostomy-en-Y was the type of drainage chosen in 16 cases, and an end-to-side technique was used in 15 patients. Side-to-side choledochoduodenostomy was performed in two cases. In 14 patients, biliary drainage was associated with other surgical procedures on the pancreatic parenchyma. No postoperative complications due to the biliary drainage occurred in this series.

Abstract Objective To investigate the outcome after surgery directed by pathological anatomy of chronic pancreatitis and provide evidence for surgical procedures. Methods The clinical material of 60 patients with chronic pancreatitis who underwent surgical treatment between 2000 and 2010 were investigated retrospectively. Result 43 cases (71.7%) presented with abdominal pain, Perioperative mortality was 1.7% (1 case). Forty-two patients with abdominal pain were all relieved after surgery, but long-term recurrence occered in 17 cases (40.5%). Modified Puestow procedure was performed on 21 patients with dilatation of pancreatic duct and/or lithiasis, long-term pain recurrence occered in 8 cases (38.1%); Six patients undergoing pancreatic head resection had no recurrence in the long-term follow-up; Pain recurrence rate of 11 cases with only cholangioenterostomy was 81.2% (9 cases) within 2 years. Chronic pancreatitis with common bile duct obstruction occurred in 33 cases(55%), cholangioenterostomy alone or combined with partly pancreatic resection or pancreatic duct drainage procedures could alleviate symptoms of biliary obstruction, 4(33.3%) cases after pure biliary drainage emerged abdominal pain, 5 cases of pancreatic head resection had no recurrence of jaundice and abdominal pain after long-term follow-up. Conclusion Surgical procedures should be selected according to the pathological anatomy of chronic pancreatitis. Reasonable pancreatic head resection and adequate bile and/or pancreatic drainage could significantly improve the long-term outcomes.     

慢性胰腺炎致梗阻性黄疸的外科治疗方式与合理性分析

目的探讨慢性胰腺炎所致梗阻性黄疸的外科治疗及其合理性.方法回顾性研究我院1985年1月至2004年12月20例慢性胰腺炎伴非结石性梗阻性黄疸的临床特点及诊治措施.结果（1）本组病例主诉黄疸,90.0%无典型慢性胰腺炎临床表现及影像特征,胰内段胆总管狭窄是特征性影像表现;（2）本组病理诊断为弥漫性胰腺慢性炎症,并造成胰内段胆总管狭窄;（3）本组选择Oddi括约肌成形术（2例）或胆肠吻合术（18例）,胆道引流效果稳定;（4）单纯T管引流者无法撤除引流管.结论本研究关注慢性胰腺炎病例中伴胆道梗阻,但缺乏典型临床及影像表现者,占同期住院慢性胰腺炎的15.0%;其伴发梗阻性黄疸与胰腺炎症直接相关;胆道引流术可缓解梗阻,胆囊或胆总管空肠吻合是安全、经济的治疗措施;单纯T管引流不是理想的选择;无胰管病变及慢性胰腺炎其他症状时无须针对胰腺进行手术操作.     

Spontaneous passage of bile duct stones: frequency of occurrence and relation to clinical presentation

BACKGROUND: Little is known about the spontaneous passage of bile duct stones. The aim of this study was to determine the rate of spontaneous stone passage and relate it to the clinical presentation of the bile duct stone. PATIENTS AND METHODS: Prospectively collected data were studied on a total of 1000 consecutive patients undergoing laparoscopic cholecystectomy with or without laparoscopic common duct exploration. Comparisons were made between 142 patients with common bile duct stones (CBDS), 468 patients who had no previous or current evidence of duct stones, and 390 patients who had good evidence of previous duct stones but none at the time of cholecystectomy. The evidence used for previous duct stones included a good history of jaundice or pancreatitis. In patients with biliary colic or cholecystitis, abnormal pre-operative liver function tests and/or a dilated common bile duct were taken as evidence of bile duct stones. RESULTS: Of the 1000 patients studied, 532 had evidence of stones in the common bile duct at some time prior to cholecystectomy. At the time of operation, only 142 patients had bile duct stones. By implication, 80%, 84%, 93% and 55% of patients presenting with pancreatitis, colic, cholecystitis and jaundice (73% overall) had passed their bile duct stones spontaneously. All 4 patients with cholangitis had duct stones at the time of operation. CONCLUSIONS: It is likely that most bile duct stones (3 in 4) pass spontaneously, especially after pancreatitis, biliary colic and cholecystitis but less commonly after jaundice. Cholangitis appears to be always associated with the presence of duct stones at the time of operation.     

Surgical therapy of inflammatory and malignant strictures of the common bile duct

Although there are growing possibilities of interventional endoscopic treatment of benign and malignant stenosis of the distal common bile duct the definitive operative drainage by terminolateral hepaticojejunostomy is in many cases the therapy of choice. In patients with chronic pancreatitis and bile duct stricture the modified duodenum preserving pancreatic head resection ("Beger operation") enables a resection of the inflammatory mass together with a drainage of the bile. Of 391 patients from our clinic being operated due to a bile duct stricture 337 underwent a biliary drainage together with a pancreatic head resection. Early postoperative biliary complications were in 0.3 % strictures of the duct and 1.5 % bile fistulas. Half of those complications could be managed conservatively. In high volume centers the operative therapy of distal common bile duct stenosis is a safe procedure with high patency rate.     

Management of Biliary and Duodenal Complications of Chronic Pancreatitis

Biliary stricture and duodenal obstruction have been increasingly recognized as complications of chronic pancreatitis. The anatomical relationship of the distal common bile duct and the duodenum with the head of the pancreas is the main factor for their involvement in chronic pancreatitis. In hospitalized patients with pancreatitis, the incidence of biliary stricture and duodenal obstruction is reported to be about 6% and 1.2%, respectively. For patients requiring an operation for chronic pancreatitis the incidence increases to 35% for biliary stricture and 12% for duodenal obstruction. Fibrosis around the distal common bile duct can cause stenosis with obstruction of bile flow. Clinically, the presentation of these patients ranges from being asymptomatic with elevated alkaline phosphatase or bilirubin, or both, to being septic with cholangitis. Jaundice, cholangitis, hyperbilirubinemia, and persistent elevation of serum alkaline phosphatase occur more frequently in patients with pancreatitis with a biliary stricture. A twofold elevation of alkaline phosphatase is a marker of possible common duct stenosis in patients with chronic pancreatitis. The incidence of both biliary cirrhosis and cholangitis in these patients is about 10%. ERCP reveals a characteristic long, smoothly tapered stricture of the intrapancreatic common bile duct. In duodenal obstruction, the factors that convert self-limiting edema to chronic fibrosis and stricture formation are unknown, but ischemia superimposed on inflammation may be the major cause. These patients present with a prolonged history of nausea and vomiting. Barium studies typically show a long constricting lesion of the duodenum, and endoscopy reveals reactive inflammatory changes in a narrowed duodenum. Operation is indicated in patients with common bile duct strictures secondary to chronic pancreatitis when there is evidence of cholangitis, biliary cirrhosis, common duct stones, progression of stricture, elevation of alkaline phophatase and/or bilirubin for over a month, and an inability to rule out cancer. The operation of choice is either choledochoduodenostomy or choledochojejunostomy. A cholecystoenterostomy is less favored because of its higher failure rate (23%). Endoscopic stenting plays a role in patients who are unfit for surgery, but it is not recommended as definitive therapy. For duodenal obstruction, failure to resolve the obstruction with 1–2 weeks of conservative therapy is an indication for bypass. The operation of choice is a gastrojejunostomy. Not uncommonly, combined obstruction of the pancreatic duct, common bile duct, and duodenum will develop. Combined drainage procedures or resection are used to manage these problems.     

Combined pancreatic duct and upper gastrointestinal and biliary tract drainage in chronic pancreatitis

In 55 patients undergoing pancreaticojejunostomy for intractable abdominal pain, common bile duct obstruction occurred in 29% (16/55) and duodenal obstruction occurred in 15% (8/55). Serum alkaline phosphatase and total and direct serum bilirubin levels were significantly higher in patients with intrapancreatic common bile duct stenosis. Transient upper gastrointestinal (UGI) tract obstruction was common with chronic pancreatitis; however, if symptoms persisted beyond 2 weeks, fixed duodenal obstruction was likely. Endoscopic retrograde cholangiopancreatography and UGI roentgenograms and endoscopy were useful in confirming mechanical obstruction to the biliary and UGI tracts, respectively. There was no difference in operative mortality and morbidity from combined drainage procedures compared with pancreaticojejunostomy alone. The biliary and UGI tracts should be investigated in symptomatic patients both before and after pancreaticojejunostomy. Combined drainage of the pancreatic duct and UGI and biliary tract is safe and effective treatment for obstructing complications of chronic pancreatitis.     

Extrahepatic biliary obstruction associated with pancreatitis.

A total of 40 patients with pancreatitis had associated extrahepatic biliary obstruction. Eighteen had biliary-induced pancreatitis. Comprehensive correction of the biliary tract disease, including cholecystectomy, common duct exploration and, when indicated, transduodenal sphincteroplasty, resulted in a high recovery rate (83%) with no recurrence of pancreatitis. Twenty-two patients had chronic pancreatitis with involvement of the terminal biliary tract by a long tapering stenosis. Nineteen of these patients had chronic fibrocalcific pancreatitis secondary to chronic alcohol abuse. In five patients, the stenosis produced a high grade obstruction which required biliary bypass with choledochoduodenostomy (four) or cholecystoduodenostomy (one). The remaining 14 patients maintained patency of the biliary tract following correction of the underlying pancreatic pathology. The latter consisted of drainage (nine) or resection (five) of 14 associated pseudocysts (present in 64% of the 22 patients), combined with side-to-side pancreaticojejunostomy to decompress an obstruction of the major pancreatic duct. In assessing the degree of terminal bile duct stenosis, calibration of the duct with Bakes dilators or rubber catheters was a useful aid. Two of the 22 patients ultimately proved to have carcinomas, producing obstruction of the pancreatic duct in the head of the gland. Both were treated initially with choledochoduodenostomy. This possibility must be considered in the management of these patients.     

BENIGN BILIARY STRICTURES ASSOCIATED WITH CHRONIC PANCREATITIS AND GALLSTONES

A series of twenty-seven patients with benign non-traumatic biliary strictures is presented. Fifteen strictures were associated with chronic pancreatitis, and were typically long, tapered Strictures of the intrapancreatic portion of the common bile duct. Twelve were associated with choledocho-lithiasis; these were usually short-segment and occurred both above and below stones in the duct. These strictures are important surgically, since they may produce pain, cholestasis and cholangitis, stone formation, and biliary cirrhosis. They may be difficult to distinguish from bile duct or pancreatic carcinomas. In the patients with chronic pancreatitis, treatment by biliary bypass was effective in the presence of cholestasis, but was ineffective for chronic pain. Treatment by biliary bypass or sphincteroplasty was highly effective in those patients with choledocholithiasis.

Duodenum-preserving pancreatic head resection leads to relief of common bile duct stenosis

BACKGROUND: Common bile duct stenosis (CBDS) is one of the most frequent complications in chronic pancreatitis with inflammatory mass in the head of the pancreas (IMH). METHODS: A total of 474 patients who underwent duodenum-preserving pancreatic head resection (DPPHR) between 1982 and 1998 were reevaluated; 219 patients (46%) with a mean duration of the disease of 45 months had a radiologically proven CBDS. RESULTS: One patient (0.5%) died of septic complications in the early postoperative course, 15 patients (6.8%) had to be reoperated on for complications. A follow-up investigation of 143 patients (92%) revealed a late mortality of 12%; no patient died of biliary complications. Seventy-five percent of the patients were completely free of pain, and 85% of the patients had a constant or even increasing body weight. CONCLUSIONS: The high percentage of pain-free patients with improved physical status and economical rehabilitation demonstrates the improvement of the quality of life after DPPHR for complicated chronic pancreatitis.     

Jaundice and chronic pancreatitis: common bile duct compression by pancreatic pseudocyst

In chronic pancreatitis, obstructive jaundice solely due to common bile duct compression by a pancreatic pseudocyst is highly unusual. In most of these cases, the jaundice is due to fibrotic stricture of the intrapancreatic portion of the common bile duct. We report two cases of obstructive jaundice in chronic pancreatitis with pseudocyst. Operative findings and follow-up during the postoperative period demonstrated compression by the pseudocyst over the common bile duct as the only etiologic factor of the jaundice. We believe that intraoperative cholangiography should be performed after drainage of a pseudocyst to correctly assess the etiology of obstruction.     

急性胆囊炎行腹腔镜胆囊切除术胆管损伤的原因和处理

目的探讨急性胆囊炎行腹腔镜胆囊切除术（laparoscopic cholecystectomy,LC）胆管损伤的预防和处理。方法回顾性分析我院1999年10月～2008年10月368例急性胆囊炎行LC导致胆管损伤7例的临床资料,根据胆管损伤轻重采取修补或胆总管空肠Roux—en—Y吻合术,并置T管引流。结果5例术中发现胆管损伤均中转开腹,其中1例胆总管横行剪断和1例电灼伤分别于术后12、3个月拔除T管后出现胆管狭窄,再次手术行胆肠Roux—en-Y吻合术治愈;2例电钩伤行胆管修补、T管引流3个月造影示无狭窄拔管治愈;1例胆总管破损严重行胆总管空肠Roux—en—Y吻合术并置T管支撑引流,住院2周带管出院,1个月后经T管胆肠造影显示通畅拔管痊愈。2例术后3～5d出现黄疸,内镜逆行胰胆管造影提示1例胆管狭窄,1例胆管完全闭锁,开腹探查证实为胆总管完全夹闭、肝总管部分夹闭各1例,分别行胆管空肠Roux—en-Y吻合术并置T管支撑引流术治愈。7例随访0．5～6年,平均3．4年,无胆管狭窄、残余结石等并发症发生。无一例死亡。结论只要正确把握手术时机、掌握好手术技巧、及时正确的中转开腹,急性胆囊炎行LC胆管损伤可避免或减少。     

腹腔镜下经腹顺行推进法T管双导管捆绑支撑引流术45例

目的探讨在腹腔镜胆总管切开胆管镜探查取石术中采用腹腔镜下经腹顺行推进法T管双导管(T形管＋2根裁剪后的鼻胆管导管)捆绑支撑引流术(LCTBS)联合治疗胆囊结石、胆总管结石、合并的十二指肠乳头部梗阻或狭窄的应用体会。 方法回顾性分析2001年4月至2018年6月期间符合入选标准的45例患者的临床资料。 结果本组45例患者行胆囊切除术、行胆总管切开胆管镜取石术,必要时行冲击波碎石术。预先行逐级导管乳头扩张术、后行T形管＋双导管支撑引流术86.7% (39/45),行逐级导管联合球囊导管乳头扩张术、T形管＋双导管支撑引流术4.4% (2/45),行乳头扩张术失败而改为内镜乳头切开术、T形管＋双导管支撑引流术6.7% (3/45),双导管支撑引流放置失败而改为T管引流术2.2% (1/45)。无残余结石。胆漏1例(2.2%)。经T管瘘道拔除双导管支撑引流管无失败病例。术后无肠穿孔和胆管穿孔,无大出血,无重症胰腺炎,无非计划再次手术病例,无死亡病例。手术并发症发生率为2.2%(1/45)。 结论从本文有限病例进行初步研究发现,只要病例选择合适,LCTBS治疗胆囊结石、胆总管结石、合并十二指肠乳头部梗阻或狭窄是可行、有效和安全的。
