Laparoscopic Left Liver Sectoriectomy of Caroli's Disease Limited to Segment II and III

Caroli''s disease is defined as a abnormal dilatation of the intra-hepatica bile ducts: Its incidence is extremely low (1 in 1,000,000 population) and in most of the cases the whole liver is interested and liver transplantation is the treatment of choice. In case of dilatation limited to the left or right lobe, liver resection can be performed. For many year the standard approach for liver resection has been a formal laparotomy by means of a large incision of abdomen that is characterized by significant post-operatie morbidity. More recently, minimally invasive, laparoscopic approach has been proposed as possible surgical technique for liver resection both for benign and malignant diseases. The main benefits of the minimally invasive approach is represented by a significant reduction of the surgical trauma that allows a faster recovery a less post-operative complications.This video shows a case of Caroli s disease occured in a 58 years old male admitted at the gastroenterology department for sudden onset of abdominal pain associated with fever (>38C° ), nausea and shivering. Abdominal ultrasound demonstrated a significant dilatation of intra-hepatic left sited bile ducts with no evidences of gallbladder or common bile duct stones. Such findings were confirmed abdominal high resolution computer tomography. Laparoscopic left sectoriectomy was planned. Five trocars and 30° optic was used, exploration of the abdominal cavity showed no adhesions or evidences of other diseases.In order to control blood inflow to the liver, vascular clamp was placed on the hepatic pedicle (Pringle s manouvre), Parenchymal division is carried out with a combined use of 5 mm bipolar forceps and 5 mm ultrasonic dissector. A severely dilated left hepatic duct was isolated and divided using a 45mm endoscopic vascular stapler. Liver dissection was continued up to isolation of the main left portal branch that was then divided with a further cartridge of 45 mm vascular stapler.At his point the left liver remains attached only by the left hepatic vein: division of the triangular ligament was performed using monopolar hook and the hepatic vein isolated and the divided using vascular stapler.Haemostatis was refined by application of argon beam coagulation and no bleeding was revealed even after removal of the vascular clamp (total Pringle s time 27 minutes).Postoperative course was uneventful, minimal elevation of the liver function tests was recorded in post-operative day 1 but returned to normal at discharged on post-operative day 3.Open in a separate windowClick here to view.^{(26M, flv)}     

塑料胆道支架引流术治疗复杂性胆总管结石的临床研究

目的:探讨内镜下逆行胰胆管造影术(ERCP)下塑料胆道支架引流术治疗复杂性胆总管结石的临床疗效和安全性。方法:回顾性分析2011年9月至2013年9月在我院经ERCP下胆道支架引流术治疗的32例复杂性胆总管结石患者的临床病例资料。结果:32例患者塑料胆道支架引流术全部成功,平均手术时间15-30分钟。术后,2例发生高淀粉酶血症,经禁食72小时后恢复正常,无穿孔、消化道大出血等ERCP严重并发症发生。术后1周,患者腹痛、发热消失,转氨酶及胆红素水平明显下降,平均住院时间6-15天。3个月复查B超,发现结石缩小19例,结石碎裂1例,支架脱落1例。术后7天、术后3个月的肝功能指标与术前比较均显著改善,差异均有统计学意义(P0.05)。结论:ERCP下塑料胆道支架引流术是一种复杂性胆总管结石安全有效的治疗方法,具有创伤小、风险较低、操作时间短、患者易耐受及手术成功率高等优点。     

医源性胆管损伤行肝切除术的指征探讨

医源性胆管损伤(IBDI)是腹腔镜胆囊切除术中最常见的并发症。复杂的医源性胆管损伤涉及肝汇流的中断和肝脏血管的损伤,对复杂的医源性胆管损伤患者施行的肝部分切除的目的是去除血管或感染性病变引起的肝实质纤维化和肝萎缩,可以彻底消除胆道狭窄、胆汁淤积及反复发作的胆管炎。肝切除术在医源性胆管损伤的手术治疗中并不是一个标准及必需的程序,但却应被视为对胆囊切除术后胆管损伤外科治疗中的一部分。     

SPECIALTY CONFERENCE: The Treatment of Retained Gallstones

Various techniques are available to evaluate patients suspected of having common duct stones before an operation on the biliary tract. In patients without jaundice, intravenous cholangiography with tomography may provide satisfactory visualization of the biliary system and its contents. Sonography and computerized axial tomography are useful noninvasive methods. Endoscopic retrograde and transhepatic cholangiography are invasive techniques; but, when successful, they provide the most precise preoperative information obtainable about the presence or absence of stones in the biliary system. The most appropriate diagnostic procedures must be carefully selected for each patient. Each year in 3,000 to 4,000 cases, stones are found remaining in the bile ducts after common duct exploration for the removal of stones. Retained stones can be treated by nonoperative extraction, by irrigation techniques and by surgical removal. Extraction methods probably deserve first consideration, if experienced personnel are available. The technique of irrigation of the common bile duct with cholic acid or other solutions, although limited in success, may also be tried; if these procedures fail, then reoperation is indicated.     

复发性胆源性胰腺炎的临床特征及危险因素分析

目的:研究复发性胆源性胰腺炎(RGP)的临床特征及危险因素。方法:选择从2012年1月至2017年1月在本院接受治疗的80例RGP患者作为观察组,另选同期在本院接受治疗的胆源性胰腺炎(GP)患者86例作为对照组,分析观察组患者的临床特征及两组患者的致病因素,采用Logistic回归分析RGP的危险因素。结果:在RGP患者的临床特征中,复发次数均较多,平均达到(3.21±0.23)次。发病诱因则主要是胆囊结石、胆总管结石及高脂血症;临床症状主要是黄疸、呕吐、恶心、腹痛、腹胀;并发症主要包括胆管炎、胰腺脓肿以及腹水;临床体征主要有出血征象、腹肌紧张、腹部压痛等。观察组的男性、重度胰腺炎、合并胆总管结石、胆胰管开口狭窄、有高脂血症、手术治疗的患者致病率分别高于对照组,并且观察组急性生理与慢性健康评分(APACHE-Ⅱ)明显高于对照组,差异均有统计学意义(P0.05)。由多因素Logistic回归分析可知,导致RGP的危险因素有男性、高APACHE-Ⅱ评分、重度胰腺炎、合并胆总管结石、胆胰管开口狭窄、有高脂血症以及手术治疗。结论:RGP患者的临床特征具有一定的规律性,其中男性、高APACHE-Ⅱ评分、重度胰腺炎、合并胆总管结石、胆胰管开口狭窄、有高脂血症以及手术治疗是导致RGP发生的危险因素。     

Transhepatic Cholangiography

Percutaneous transhepatic cholangiography is a method of visualizing the biliary tree by the injection of radio-opaque medium through the abdominal wall and liver into an intrahepatic bile duct. The procedure is indicated in the immediate preoperative evaluation of patients with obstructive jaundice of unknown etiology and is usually diagnostic in these cases. It may also be of value in avoiding operation in poor-risk patients with obstructive jaundice. Biliary leak resulting in chemical peritonitis is a complication in about 5% of these procedures. Intraperitoneal hemorrhage is a complication in less than 1%. Death results from the procedure in less than 0.5% of cases. Transhepatic cholangiography during surgical operation is of value in demonstrating obstructive lesions of the bile ducts. However, preoperative percutaneous transhepatic cholangiography is preferred, since it makes possible adequate preparation for technically difficult repairs and resections.     

Non-operative removal of bile duct stones by duodenoscopic sphincterotomy in the elderly.

Between January 1975 and December 1979, 71 patients over the age of 70 underwent attempted duodenoscopic sphincterotomy for stones in the common bile duct. Fifteen patients still had gall bladders in situ. Sphincterotomy was possible in 69 of the patients and in 65 of these duct clearance was achieved, giving an overall success rate of 92%. Failure to achieve sphincterotomy in two cases was due to substantial peripapillary diverticula. Duct clearance failed in four patients, mostly due to the size of the retained stones. The largest stone extracted was 24 mm diameter. There were no deaths but complications occurred in nine patients (13%); these were haemorrhage in four (requiring surgery in one), cholangitis in four (two of whom required surgical extraction of stones), and pancreatitis in one. The average duration of hospital stay in successful cases was 11 days (range three to 30). Clinical follow-up of 55 patients one to five years after sphincterotomy showed no evidence of stones or of stenosis of the sphincter. Duodenoscopic sphincterotomy is a major advance in the management of elderly patients with stones in the common bile duct.     

Intraductal papillary neoplasms of bile duct. A distinct entity like its counterpart in pancreas

To recognize the new entity-intraductal papillary neoplasia of bile duct in liver, the authors reviewed the clinical records of sixteen patients, analyzed the microscopic features, and selected immunohistochemical reactivity (cytokeratins and mucins) that might correlate with classification. Ten patients were male and six were female, with a mean age of 58 years (range, 21-73 years). According to their cell phenotypes, these papillary tumors were classified as intestinal type (6 cases), pancratobiliary type (4 cases), gastric type (5 cases) and oncocytic type (1 case). Most were located in the left hepatic duct and accompanied with bile duct dilatation (10 cases). Eight showed minimal expansile invasion into the ductal wall and eight were noninvasive. Five patients were treated with a hepatectomy, three underwent segmental resections, and one underwent a left hepatic lobectomy. One patient died of unrelated causes 6 years after operation, and another died of postoperative complications. The remaining 7 patients are alive and disease free 1-5 years after surgery. Because of its distinct clinical, pathological features and a favorable prognosis can be expected after complete surgical resection, we suggested that intraductal papillary neoplasia should be distinguished from other types of peripheral cholangiocarcinoma, as a distinct entity, like its counterparts in the pancreas. Neoexpressed and overexpressed mucins are of clinical value as a marker for supportive diagnosis, prognosis or monitoring therapy.     

Klatskin tumor--results of surgical therapy

Between January 1st 1990 and December 31st 1999, 24 patients affected by Klatskin tumor underwent operation in our department of surgery. According to Bismuth's classification, there were 0 (0%) type I, 5 (21%) type II, 6 (25%) type IIIa, 4 (17%) type IIIb and 9 (37%) type IV tumors. Five patients (21%) were treated by curative resection (group I) while in 14 patients (58%) palliative surgical procedure was performed (group II). In 5 cases (21%) the extension of malignancy did not allowed any procedure (group III). Curative resection for malignant tumors of the hepatic duct bifurcation included wide tumor excision and bile duct resection at the liver hilum (with wedge hepatic resection in one patient) and creation of biliary-enteric anastomosis. Palliative surgical procedure included stent insertion. Jaundice was completely relieved in all patients undergoing resection, since 3 patients (21%) after stenting hadn't satisfactory biliary drainage. There was 1 (20%) perioperative death in the group 1, while in group 2, 5 patients (36%) died postoperatively. In this series, the mean postoperative survival of all patients was 16 months. The mean postoperative survival of patients undergoing localized tumor resection with curative intent was 38 months, in contrast to 10 months for those undergoing operative stent insertion. in addition, only 1 patient from group III, in whom only exploratory surgery were performed survived 7 months, while other 4 patients died in the hospital. This retrospective review suggests that aggressive surgical treatment could improve survival and quality of life in patients suffering from Klatskin tumor.     

内镜下乳头括约肌切开术联合不同时长气囊扩张术治疗胆总管结石的疗效观察

摘要 目的：探讨内镜下乳头括约肌小切开术( endoscopic sphincterotomy,EST)联合不同时长持续时间十二指肠乳头气囊扩张术（Endoscopic papillary balloon dilatation,,EPBD）对胆总管结石患者治疗效果差异。方法：选择2018年1月至2018年12月于我院接受EST联合EPBD治疗的92例胆总管结石患者为研究对象, 按照其术中气囊扩张时间的不同将其分为A组（46例,扩张时间20 s）、B组（46例,扩张时间40 s）,对比两组患者一次净石率、机械碎石率、操作时间及X线暴露时间,对比两组患者术前及术后肝功能指标,术后12 h血淀粉酶,对比两组患者术后胰腺炎、消化道出血、胆道感染、穿孔等并发症的发生率。结果：（1）对比显示两组患者一次净石率、机械碎石率、操作时间、X线暴露时间及12 h血淀粉酶对比差异不具有统计学意义（P>0.05）;（2）术前两组患者总胆红素(Total bilirubin,TBIL)、谷氨酸转氨酶(Glutamate aminotransferase,ALT)、碱性磷酸酶(alkaline phosphatase,ALP)对比差异不具有统计学意义（P>0.05）,术后两组患者上述指标均较治疗前出现明显的下降,但组间比较无差异（P>0.05）;（3）A组患者术后各类并发症发生率为4.35 %（2/46）,B组患者术后各类并发症发生率为17.39 %（8/46）,两组对比差异具有统计学意义（P<0.05）。结论：EST联合EPBD对胆总管结石具有较好的治疗效果,术中不同气囊扩张时间不会对手术成功率、手术时间等指标造成影响,但长时间扩张存在增加术后出血的风险,建议在能够正常实施手术的情况下尽量控制术中气囊扩张时间。

Diagnosis and Treatment of Xanthogranulomatous Cholecystitis: A Report of 39 Cases

This study focuses on providing diagnosis and treatment for xanthogranulomatous cholecystitis (XGC). Clinical data from 39 patients diagnosed with XGC by pathological examination between 2002 and 2010 were analyzed retrospectively. As a result, in this group of patients, the male to female ratio was 30:9 and the average age of XGC onset was 62.2?years. Clinical manifestation of the disease was similar to general cholecystitis and preoperative CT examination showed that there were only 4 XGC cases, while the others were possibly misdiagnosed. Intraoperative observations showed that all the patients had gallbladder wall thickening. This was associated with gallbladder stones in 37 patients (94.9?%), choledocholith in 11 patients (28.2?%), and Mirizzi syndrome in 5 patients (12.8?%). In this study, intraoperative frozen section pathology was conducted in 14 patients and no gallbladder cancer was found. Laparoscopic cholecystectomy was performed on 7 patients, of which two were transferred to laparotomy. Of the remaining 32 cases, 25 were subjected to open cholecystectomy, 3 to partial cholecystectomy, and 4 to the cholecystectomy and partial liver wedge resection. It was concluded that XGC is a unique type of cholecystitis with atypical clinical manifestations and is often difficult to diagnose preoperatively. Pathological examination is a key to diagnose XGC and cholecystectomy is the primary surgical treatment. In patients with choledochectasia or jaundice, for whom we cannot exclude calculus of common bile duct, common bile duct exploration should be considered. The prognosis of XGC appears to be good with the above approaches.

钬激光在胆总管下段嵌顿结石术中的应用

目的探讨钬激光在胆总管下段嵌顿性结石手术中的应用价值。方法通过腹腔镜下胆道镜工作通道,应用钬激光,功率为0．6—0．8J／10Hz,直径为200um光导纤维,在直视下接触结石,将嵌顿结石击碎后注水冲出,或用取石篮套出。结果11例均取石碎石成功,手术时间75—205min,平均95．5min,出血80—130ml,平均89．4ml。平均住院8．2d。术后无胆道出血,胆漏。术后2W照影无结石残留,胆总管下段通畅无胆道狭窄。术后肝功能2W恢复正常6例,5例1月均恢复正常。随访3—6月未见结石复发。结论钬激光治疗胆总管下段嵌顿结石,具有创伤小、恢复快、碎石确切、操作容易、安全有效等优点,为治疗复杂性胆总管结石开辟了一条新的治疗途径。     

Cholecystostomy: Its Place in the Treatment of Acute Cholecystitis

Conservative management of acute cholecystitis has frequently been too prolonged, particularly in the aged. Early cholecystostomy followed by interval cholecystectomy improved the results of treatment as demonstrated in a series of 41 patients at Shaughnessy Veterans Hospital, Vancouver. The following advantages were noted. Advanced disease in the elderly toxic patient was successfully treated by a minor and short surgical procedure, cholecystostomy. Per-cholecystostomy cholangiography revealed dilatation and/or stones in the common bile duct. Interval cholecystectomy was facilitated by the absence of general toxicity, by the presence of a subsiding inflammatory process, and by the availability preoperatively of knowledge of the status of the common bile duct.     

The Prevention of Residual Biliary Calculi

Residual calculi following cholecystectomy may be expected in approximately seven percent of cases. The vast majority of these are overlooked during operation; truly re-formed stones are rare.Calculi are missed during cholecystectomy because of failure to explore the common bile duct. This is due to (1) the presence of silent choledochal stones, and (2) reliance on negative cystic duct cholangiograms in the presence of indications for common duct exploration.Overlooking of silent stones during cholecystectomy may be prevented by routine operative cholangiography. Ideally, false-negative cystic duct cholangiograms should be eliminated by the use of fluoroscopic cholangiography.Retained calculi following duct exploration may be prevented by (a) routine biliary endoscopy and (b) completion fluoroscopic cholangiography.Re-formation of ductal calculi can probably be prevented by appropriate biliary drainage procedures performed during the initial choledochotomy. Selection of patients for primary biliary decompression remains an experimental problem.     

Comparative Evaluation of Two Laparoscopic Procedures for Treating Common Bile Duct Stones

Cholesystolithiasis is often associated with common bile duct stones (CBDS). In order to assess the choice of surgery in terms of effectiveness and complications in the treatment of CBDS, we have compared three surgical procedures, viz., laparoscopic choledocholithotomy T-tube drainage (LCH-TD), laparoscopic cholecystectomy with endoscopic sphincterotomy (LC-EST), and the traditional open choledocholithotomy with T-tube drainage (OCHTD). This study is a retrospective comparative analysis of LCH-TD (77 patients), LC-EST (43 patients), and OCHTD (60 patients) for CBDS. The success of the surgical procedures was assessed in terms of recovery duration, hospitalization, and post-operative complications. Both the micro-invasive procedures, LCH-TD and LC-EST, with a success rate of 92.5%, are found to be superior to the traditional OCHTD. Between the two micro-invasive procedures, patients in LCH-TD group had shorter operation time and hospital stay, and fewer post-operative complications. Although the size of the stones is comparable between these two groups, the CBD diameter was significantly larger in patients who underwent LCH-TD. In comparison to OCHTD, both LCH-TD and LC-EST are micro-invasive, safe, and suitable for routine use in patients with CBDS. Moreover, when the CBD diameter is wider than 1 cm, LCH-TD is strongly advocated.
