Risk Factors Associated with Acute Pancreatitis after Percutaneous Biliary Intervention: We Do Not Know Nearly Enough. Gastroenterol Res Pract 2023; 2023:9563074. [PMID: 36644482 PMCID: PMC9839406 DOI: 10.1155/2023/9563074] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/18/2022] [Revised: 12/09/2022] [Accepted: 12/28/2022] [Indexed: 01/09/2023] Open
Abstract
Percutaneous transhepatic cholangiodrainage (PTCD) and percutaneous transhepatic biliary stenting (PTBS) may be used as a palliative treatment for inoperable patients with malignant biliary obstruction (MBO) to improve the prognosis and their quality of life. However, acute pancreatitis is a common and severe complication that cannot be ignored after PTCD and PTBS in patients with MBO. A few cases may develop severe pancreatitis with a higher mortality rate. In this study, we summarize the known risk factors for acute pancreatitis after percutaneous biliary interventional procedures and investigate possible risk factors to reduce its occurrence by early identifying high-risk patients and taking appropriate measures.

Abstract
BACKGROUND Utilization of preoperative biliary drainage prior to pancreatoduodenectomy for patients with pancreatic ductal adenocarcinoma and obstructive jaundice remains controversial. METHODS All patients that underwent pancreatoduodenectomy for pancreatic ductal adenocarcinoma at the authors' institution were analyzed retrospectively to evaluate the effect of endoscopic biliary drainage on postoperative outcomes and long-term survival. Age, gender, ASA-Score, operative time, blood loss, intraoperative transfusion rate, and postoperative complications, including postoperative pancreatic fistula, delayed gastric emptying, bleeding, bile fistula, wound infections, sepsis, pulmonary and cardiac complications as well as the need for relaparotomy were analyzed. RESULTS Two hundred eighty-five patients with similar baseline characteristics underwent pancreatoduodenectomy, 151 patients with biliary drainage (group 1) and 134 without drainage (group 2). More than 60% of patients had one or more postoperative complications, without significant difference between the two groups (P=0.140). The overall incidence of pancreatic fistula was 21.75% in both groups (group 1: 19.87% vs. group 2: 23.88%, P=0.659). Wound healing impairment was the only postoperative complication that differed significantly between the two groups (group 1: 24.50% vs. group 2: 8.96%, P<0.001). In multivariate risk analysis, biliary drainage was the only independent risk factor for wound healing impairment (OR 4.126; 95% CI: 1.295-13.143; P=0.017). The median overall survival was similar in both groups. CONCLUSIONS Preoperative endoscopic biliary drainage is associated with an increased risk for wound healing impairment and wound infections. Therefore, biliary drainage should not be used routinely in patients with obstructive jaundice prior to pancreatoduodenectomy.

Abstract
Patients with intestinal ischemia associated with acute aortic dissection often require emergent bowel resection, which results in serious complications. We present a case of successful surgical management of extensive bowel necrosis caused by acute aortic dissection. A 42-year-old man underwent emergent subtotal resection of the small intestine, right colectomy, tube gastrostomy, and transverse colostomy; however, intestinal continuity was not restored. He developed two major postoperative complications: unconsciousness due to metabolic alkalosis caused by massive discharge from the gastrostomy and jaundice due to bile salt depletion caused by disruption of the enterohepatic circulation. His serum bilirubin levels decreased after the infusion of gastric discharge through gastrostomy into the transverse colon through the colostomy; thereafter, a second operation was performed to restore gastrointestinal continuity. Overall, patients undergoing massive bowel resection without intestinal continuity require careful management of electrolytes and bile salt.

Abstract
Abstract
Background
Biliary fistula is one of the most common complications after hepatectomy. This study evaluated the effect of transcystic biliary drainage during hepatectomy on the occurrence of postoperative biliary fistula.
Methods
This multicentre RCT was carried out from 2009 to 2016 in nine centres. Patients were randomized to transcystic biliary drainage or no transcystic drainage (control). Patients underwent hepatectomy (more than 2 segments) of non-cirrhotic livers. The primary endpoint was the occurrence of biliary fistula after surgery. Secondary endpoints were morbidity, postoperative mortality, duration of hospital stay, reoperation, readmission to hospital, and complications caused by catheters. Intention-to-treat and per-protocol analyses were performed.
Results
A total of 310 patients were randomized. In intention-to-treat analysis, there were 158 patients in the transcystic group and 149 in the control group. Seven patients were removed from the per-protocol analysis owing to protocol deviations. The biliary fistula rate was 5·9 per cent in intention-to-treat and 6·0 per cent in per-protocol analyses. The rate was similar in the transcystic and control groups (5·7 versus 6·0 per cent; P = 1·000). There were no differences in terms of morbidity (49·4 versus 46·3 per cent; P = 0·731), mortality (2·5 versus 4·7 per cent; P = 0·367) and reoperations (4·4 versus 10·1 per cent; P = 1·000). Median duration of hospital stay was longer in the transcystic group (11 versus 10 days; P = 0·042). The biliary fistula risk was associated with the width and length of the hepatic cut surface.
Conclusion
This randomized trial did not demonstrate superiority of transcystic drainage during hepatectomy in preventing biliary fistula. The use of transcystic drainage during hepatectomy to prevent postoperative biliary fistula is not recommended. Registration number: NCT01469442 ( http://www.clinicaltrials.gov).

Abstract
Hypotonic hyponatremia is caused by a serum sodium level of <135 mEq/L in the
setting of excess solute loss accompanied by free water retention because of
antidiuretic hormone release, subsequent to decreased effective arterial blood
volume. Acute hyponatremia can have various neurological manifestations,
including drowsiness, lethargy, coma, seizures, respiratory depression, and even
death. In this article, we present a case of a 41-year-old man who presented
with hyponatremia as a result of sodium containing biliary fluid loss and
resultant renal free water retention in response to increased antidiuretic
hormone secretion. He underwent placement of a cholecystostomy tube for
acalculous cholecystitis and was found to be persistently hyponatremic despite
repletion with sodium-containing fluids. Once the cholecystostomy tube was
removed, the patient’s sodium levels improved, and his symptoms resolved. Our
case highlights choleuresis as an unusual but significant cause of hyponatremia
in patients who have external biliary drainage.

Abstract
Bile duct injuries with substance loss can be challenging to treat surgically. Morbid obesity, intra-abdominal sepsis and penetrating trauma increase complexity. Endoscopic/percutaneous techniques are alternative treatment options. Combined rendezvous with immediate stenting was successful in two challenging cases.
Introduction Treatment of major iatrogenic and non-iatrogenic bile duct injury (BDI) often requires delayed surgery with interim external biliary drainage. Percutaneous transhepatic cholangiography (PTC) with biliary catheter placement and endoscopic retrograde cholangiography (ERC) with stent placement have been used to bridge defects. In some patients, bridging the defect cannot be achieved through ERC or PTC alone. Materials and methods Two patients with major BDIs, one iatrogenic and one non-iatrogenic underwent an extraluminal PTC/ERC rendezvous with placement of a fully covered self-expandable metal stent (SEMS) for the acute management of BDI with substantial loss of bile duct length. Results In both patients the intraperitoneal PTC/ERC rendezvous with SEMS placement was successful with no complications after 12 and 18 months follow-up, respectively. Discussion This study is the first to report a standardized approach to the acute management of iatrogenic and non-iatrogenic major BDIs using extraluminal intraperitoneal PTC/ERC rendezvous with placement of a fully covered SEMS. The described technique may serve as a “bridge to surgery” strategy for patients where definitive management of BDIs are deferred. However, long-term data of the success of this technique, specifically the use of a SEMS to bridge the defect, are lacking and further investigation is required to determine its role as a definitive treatment of BDIs with substance loss. Conclusion PTC/ERC rendezvous with restoration of biliary continuity and internalization of bile flow is particularly useful for patients who have previously failed ERC and/or PTC alone, and in whom immediate surgical repair is not an option.

Abstract
BACKGROUND Preoperative biliary drainage (PBD) prior to liver resection for hilar and intrahepatic cholangiocarcinoma (CCA) is common. While PBD for those with distal obstructions has been studied extensively and is associated with increased infectious complications, the impact of PBD among patients undergoing hepatectomy for non-disseminated proximal CCA has yet to be clearly elucidated. METHODS Patients undergoing liver resection between 2014 and 2016 for non-disseminated hilar and intrahepatic CCA were analyzed using the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database. Associations between PBD (percutaneous or endoscopic) and 30-day outcomes were evaluated. RESULTS There were 905 liver resections performed, with 186 (20.6%) for hilar CCA and 719 (79.4%) for intrahepatic CCA. Of those, 251/897 (28.0%) patients underwent PBD. Independent preoperative predictors of PBD were hilar CCA, major hepatectomy, open surgery, lower BMI, and higher preoperative bilirubin. Adjusting for preoperative variables, extent of resection, and bilirubin, PBD was independently associated with increased wound infection (OR 2.93), organ space infection (OR 3.63), sepsis (OR 3.17), renal insufficiency (OR 4.25), transfusion (OR 2.40), bile leak (OR 3.23), invasive intervention (OR 2.72), liver failure (OR 3.20), readmission (OR 3.01), reoperation (OR 2.32), and mortality (OR 4.24, all p < 0.05). CONCLUSIONS Among patients undergoing hepatectomy for proximal CCA, PBD is associated with increased postoperative complications. These data suggest that avoidance of routine preoperative biliary drainage may decrease short-term complications.

Abstract
The aim of the present study was to evaluate the prevalence and causes of spontaneous remission of obstructive jaundice in rats. Healthy male and female Wistar rats (180–220 g) were randomly assigned to receive common bile duct ligation (CBDL) and transection (group A), CBDL only (group B), or CBD dissection without ligation or transection (control group C; n=36 in each group). There was a difference in eye and skin jaundice prevalence between groups A and B from 14 days after surgery. The level of total bilirubin (TB) did not continue to increase in group A and began to decrease in the majority of rats in group B (P<0.05 vs. group B). At day 21 after surgery, the TB level returned to normal in group B and no significant difference was observed compared with group C. At day 21 after surgery, significant dilatation of bile ducts above the ligature was observed in group A following cholangiography with 38% meglumine diatrizoate and this contrast agent did not spread to other sites. Slight dilatation of the proximal bile ducts was observed in group B and the contrast agent entered the intestinal lumen through the omental ducts adhering to the porta hepatis. After 14 days of surgery, there were 36 rats in group A and B, and 17 rats exhibited spontaneous regression of jaundice. Overall, 47.2% (17/36) of rats experienced spontaneous remission of obstructive jaundice, 82.4% (14/17) of which underwent ligation only. The spontaneous remission of jaundice may have been caused by shunting through very small bile ducts or omental ducts adhering to the porta hepatis. If a model of biliary obstruction is to be established in future research, a model of CBDL and transection is preferable. In this case, jaundice reduction surgery should be performed 14 days after establishment of the model.

Abstract
The liver has an extraordinary regenerative capacity rapidly triggered upon injury or resection. This response is intrinsically adjusted in its initiation and termination, a property termed the "hepatostat". Several molecules have been involved in liver regeneration, and among them bile acids may play a central role. Intrahepatic levels of bile acids rapidly increase after resection. Through the activation of farnesoid X receptor (FXR), bile acids regulate their hepatic metabolism and also promote hepatocellular proliferation. FXR is also expressed in enterocytes, where bile acids stimulate the expression of fibroblast growth factor 15/19 (FGF15/19), which is released to the portal blood. Through the activation of FGFR4 on hepatocytes FGF15/19 regulates bile acids synthesis and finely tunes liver regeneration as part of the "hepatostat". Here we review the experimental evidences supporting the relevance of the FXR-FGF15/19-FGFR4 axis in liver regeneration and discuss potential therapeutic applications of FGF15/19 in the prevention of liver failure.

Abstract
Background Despite the improvements of surgical techniques and postoperative management of patients with liver transplantation, biliary complications are one of the most common and important adverse events. We present a first case of choledochoduodenostomy using magnetic compression following a massive resection of the small intestine due to strangulated ileus after living donor liver transplantation. Case presentation The 54-year-old female patient had end-stage liver disease, secondary to liver cirrhosis, due to primary sclerosing cholangitis with ulcerative colitis. Five years earlier, she had received living donor liver transplantation using a left lobe graft, with resection of the extrahepatic bile duct and Roux-en-Y anastomosis. The patient experienced sudden onset of intense abdominal pain. An emergency surgery was performed, and the diagnosis was confirmed as strangulated ileus due to twisting of the mesentery. Resection of the massive small intestine, including choledochojejunostomy, was performed. Only 70 cm of the small intestine remained. She was transferred to our hospital with an external drainage tube from the biliary cavity and jejunostomy. We initiated total parenteral nutrition, and percutaneous transhepatic biliary drainage was established to treat the cholangitis. Computed tomography revealed that the biliary duct was close to the duodenum; hence, we planned magnetic compression anastomosis of the biliary duct and the duodenum. The daughter magnet was placed in the biliary drainage tube, and the parent magnet was positioned in the bulbus duodeni using a fiberscope. Anastomosis between the left hepatic duct and the duodenum was accomplished after 25 days, and the biliary drainage stent was placed over the anastomosis to prevent re-stenosis. Contributions to the successful withdrawal of parenteral nutrition were closure of the ileostomy in the adaptive period, preservation of the ileocecal valve, internal drainage of bile, and side-to-side anastomosis. Conclusions Choledochoduodenostomy with magnet compression could be a less invasive and safer method for treatment of biliary stricture that cannot be accessed by conventional surgery.

Abstract
BACKGROUND The strategy for preoperative management of biliary obstruction in hilar cholangiocarcinoma (HCCA) patients with regards to drainage by endoscopic (EBD) or percutaneous (PTBD) methods is not clearly defined. The aim of this study was to investigate the utility, complications and therapeutic efficacy of these methods in HCCA patients, with a secondary aim to assess the use of portal vein embolization (PVE) in patients undergoing drainage. METHODS Studies incorporating HCCA patients undergoing biliary drainage prior to curative resection were included (EMBASE and Medline databases). Analyses included baseline drainage data, procedure-related complications and efficacy, post-operative parameters, and meta-analyses where applicable. RESULTS Fifteen studies were included, with EBD performed in 536 patients (52%). Unilateral drainage of the future liver remnant was undertaken in 94% of patients. There was a trend towards higher procedure conversion (RR 7.36, p = 0.07) and cholangitis (RR 3.36, p = 0.15) rates in the EBD group. Where specified, 134 (30%) drained patients had PVE, in association with a major hepatectomy in 131 patients (98%). Post-operative hepatic failure occurred in 22 (11%) of EBD patients compared to 56 (13%) of PTBD patients, whilst median 1-year survival in these groups was 91% and 73%, respectively. DISCUSSION The accepted practice is for most jaundiced HCCA patients to have preoperative drainage of the future liver remnant. EBD may be associated with more immediate procedure-related complications, although it is certainly not inferior compared to PTBD in the long term.

Abstract
BACKGROUND In literature, the reported mortality of posthepatectomy liver failure is <5 % and morbidity is 15-30 %. Around 3-8 % of patients develop liver failure after major hepatic resection. OBJECTIVE The objective of the study was to provide current definitions and managing posthepatectomy liver failure (PHLF) as per severity and ISGLS grading. METHOD A systemic search of pubmed indexed articles was done and relevant articles were selected to formulate latest guidelines for PHLF. CONCLUSION We were able to make an algorithm for standardizing management so as to identify and treat PHLF as early as possible.

Abstract
BACKGROUND Although preoperative biliary drainage in jaundiced patients is controversial, external biliary drainage (EBD) is beneficial for infection control in patients with biliary cancers. When EBD is performed, additional bile replacement (BR) has the benefit of improving impaired intestinal barrier function, but the detailed mechanism remains unknown. We examined the effect of bile replacement on immune functions over the duration of BR in jaundiced patients. METHODS Fifteen patients were enrolled into this prospective study. BR was started soon after the total serum bilirubin concentration reached 5.0 mg/dl and was continued for 14 days. Drained bile was given two times orally (2 × 100 ml/day). Concanavalin A (Con A)- and phytohemagglutinin (PHA)-stimulated lymphocyte proliferation and serum diamine oxidase (DAO) activity were measured before starting and during BR. Twenty patients with EBD and no BR were analyzed as a control group. RESULTS Serum liver enzymes, prothrombin time-international normalized ratio (PT-INR), and responses to Con A and PHA gradually improved over the 14 days of BR, but percentages of lymphocytes and DAO levels did not. PT-INR, and Con A and PHA responses did not improve during EBD in the control group. PT-INR significantly decreased in patients with a greater fraction of their drained bile replaced. CONCLUSIONS Our results indicate that preoperative BR using as large a quantity of bile as possible is useful for improving blood coagulability and cellular immunity in patients with EBD.

Abstract
BACKGROUND Preoperative jaundice is frequent in gallbladder cancer (GBC) and indicates advanced disease. Resection is rarely recommended to treat advanced GBC. An aggressive surgical approach for advanced GBC remains lacking because of the association of this disease with serious postoperative complications and poor prognosis. This study aims to re-assess the prognostic value of jaundice for the morbidity, mortality, and survival of GBC patients who underwent surgical resection with curative intent. METHODS GBC patients who underwent surgical resection with curative intent at a single institution between January 2003 and December 2012 were identified from a prospectively maintained database. RESULTS A total of 192 patients underwent surgical resection with curative intent, of whom 47 had preoperative jaundice and 145 had none. Compared with the non-jaundiced patients, the jaundiced patients had significantly longer operative time (p < 0.001) and more intra-operative bleeding (p = 0.001), frequent combined resections of adjacent organs (23.4% vs. 2.8%, p = 0.001), and postoperative complications (12.4% vs. 34%, p = 0.001). Multivariate analysis showed that preoperative jaundice was the only independent predictor of postoperative complications. The jaundiced patients had lower survival rates than the non-jaundiced patients (p < 0.001). However, lymph node metastasis and gallbladder neck tumors were the only significant risk factors of poor prognosis. Non-curative resection was the only independent predictor of poor prognosis among the jaundiced patients. The survival rates of the jaundiced patients with preoperative biliary drainage (PBD) were similar to those of the jaundiced patients without PBD (p = 0.968). No significant differences in the rate of postoperative intra-abdominal abscesses were found between the jaundiced patients with and without PBD (n = 4, 21.1% vs. n = 5, 17.9%, p = 0.787). CONCLUSIONS Preoperative jaundice indicates poor prognosis and high postoperative morbidity but is not a surgical contraindication. Gallbladder neck tumors significantly increase the surgical difficulty and reduce the opportunities for radical resection. Gallbladder neck tumors can independently predict poor outcome. PBD correlates with neither a low rate of postoperative intra-abdominal abscesses nor a high survival rate.

Abstract
BACKGROUND Obstructive jaundice in patients with hilar cholangiocarcinoma is a known risk factor for hepatic failure after liver resection. Plastic stents are most widely used for preoperative drainage. However, plastic stents are known to have limited patency time and therefore, in palliative settings, the self-expanding metal stent (SEMS) is used. This type of stent has been shown to be superior because it allows for rapid biliary decompression and a reduced complication rate after insertion. This study explores the use of the SEMS for biliary decompression in patients with operable hilar cholangiocarcinoma. METHODS A retrospective evaluation of a prospectively maintained database at a tertiary hepatobiliary referral centre was carried out. All patients with resectable cholangiocarcinoma were recorded. RESULTS Of 260 patients referred to this unit with cholangiocarcinoma between January 2008 and April 2012, 50 patients presented with operable cholangiocarcinoma and 27 of these had obstructive jaundice requiring stenting. Ten patients were initially treated with SEMSs; no stent failure occurred in these patients. Seventeen patients initially received plastic stents, seven of which failed in the interval between stent placement and laparotomy. These stents were replaced by SEMSs in four patients and by plastic stents in three patients. Median time to laparotomy was 45 days and 68 days in patients with SEMSs and plastic stents, respectively. CONCLUSIONS Self-expanding metal stents provide adequate and rapid biliary drainage in patients with obstruction caused by hilar cholangiocarcinoma. No re-interventions were required. This probably reflects the relatively short interval between stent placement and laparotomy.

Abstract
INTRODUCTION In this review of the literature, we analyze the indications for preoperative drainage in jaundiced patients who are candidates for pancreaticoduodenectomy (PD) or major hepatectomy due to periampullary or proximal bile duct neoplasms. OBJECTIVE The aim of this study is to review the literature and to report on the current management of jaundiced patients with periampullary or proximal bile duct neoplasms who are candidates for PD or major liver resection. BACKGROUND Jaundiced patients represent a major challenge for surgeons. Alterations and functional impairment caused by jaundice increase the risk of surgery; therefore, preoperative biliary decompression has been suggested. METHODS A literature review was performed in the MEDLINE database to identify studies on the management of jaundice in patients undergoing PD or liver resection. Papers considering palliative drainage in jaundiced patients were excluded. RESULTS The first group of papers considered patients affected by middle-distal obstruction from periampullary neoplasms, in which preoperative drainage was applied selectively. The second group of papers evaluated patients with biliary obstructions from proximal biliary neoplasms. In these cases, Asian authors and a few European authors considered it mandatory to drain the future liver remnant (FLR) in all patients, while American and most European authors indicated preoperative drainage only in selected cases (in malnourished patients and in those with hypoalbuminemia, cholangitis or long-term jaundice; with an FLR < 30% or 40%) given the high risk of complications of drainage (choleperitoneum, cholangitis, bleeding, and seeding). The optimal type of biliary drainage is still a matter of debate; recent studies have indicated that endoscopy is preferable to percutaneous drainage. Although the type of endoscopic biliary drainage has not been clearly established, the choice is made between plastic stents and short, covered, metallic stents, while other authors suggest the use of nasobiliary drainage. CONCLUSIONS : A multidisciplinary evaluation (made by a surgeon, biliary endoscopist, gastroenterologist, and radiologist) of jaundiced neoplastic patients should be performed before deciding to perform biliary drainage. Middle-distal obstruction in patients who are candidates for PD does not usually require routine biliary drainage. Proximal obstruction in patients who are candidates for major hepatic resection in the majority of cases requires a drain; however, the type, site, number, and approach must be defined and tailored according to the planned hepatic resection. Recently, the use of preoperative biliary drainage limited to the FLR has been a suggested strategy. However, multicenter, randomized, controlled trials should be conducted to clarify this issue.

Abstract
BACKGROUND Bile acid signalling and farnesoid X receptor activation are assumed to be essential for liver regeneration. This study was designed to investigate the association between serum bile acid levels and extent of liver regeneration after major hepatectomy. METHODS Patients who underwent left- or right-sided hemihepatectomy between 2006 and 2009 at the authors' institution were eligible for inclusion. Patients were divided into two groups: those undergoing hemihepatectomy with external bile drainage by cystic duct tube (group 1) and those having hemihepatectomy without drainage (group 2). Serum bile acid levels were measured before and after hepatectomy. Computed tomography was used to calculate liver volume before hepatectomy and remnant liver volume on day 7 after surgery. RESULTS A total of 46 patients were enrolled. Mean(s.d.) serum bile acid levels on day 3 after hemihepatectomy were significantly higher in group 2 than in group 1 (11·6(13·5) versus 2·7(2·1) µmol/l; P = 0·003). Regenerated liver volumes on day 7 after hepatectomy were significantly greater in group 2 138·1(135·9) ml versus 40·0(158·8) ml in group 1; P = 0·038). Liver regeneration volumes and rates on day 7 after hemihepatectomy were positively associated with serum bile acid levels on day 3 after hemihepatectomy (P = 0·006 and P < 0·001 respectively). The incidence of bile leakage was similar in the two groups. CONCLUSION Initial liver regeneration after major hepatectomy was less after biliary drainage and was associated with serum bile acid levels. External biliary drainage should be used judiciously after liver resection.

Abstract
Cholestasis is a clinical condition commonly encountered by both surgeons and gastroenterologists. Cholestasis can cause various physiological changes and affect the nutritional status and surgical outcomes. Study of the pathophysiological changes occurring in the liver and other organs is of importance. Various studies have been done in cholestatic rat models. We used a reversible cholestatic rat model in our recent study looking at the role of methylprednisolone in the ischemia reperfusion injury. Various techniques for creation of a reversible cholestatic model have been described. Creation of a reversible cholestatic rat model can be challenging in view of the smaller size and unique hepatopancreatobiliary anatomy in rats. This video article demonstrates the creation of a reversible cholestatic model. This model can be used in various studies, such as looking at the changes in nutritional, physiological, pathological, histological and immunological changes in the gastrointestinal tract. This model can also be used to see the effects of cholestasis and various therapeutic interventions on major hepatic surgeries.

Abstract
BACKGROUND The value of preoperative biliary drainage (PBD) before resection for hilar cholangiocarcinoma (HCCA) is still controversial nowadays. The objective of this review is to summarize quantitatively the evidence related to this issue. METHODS Two investigators independently searched the Medline, Embase, Academic Search Premier (EBSCO), Chinese BioMedical Literature on disc (CBMdisc), and Chinese Medical Current Contents (CMCC) databases. Eleven studies with a total number of 711 HCCA cases were included. Comparison was made of PBD versus no PBD in HCCA patients undergoing surgical resection. Outcome measures were postoperative complications, in-hospital death rate, postoperative infectious complications, and postoperative hospital stay. RESULTS There was no difference in death rate or postoperative hospital stay between the two treatment modalities. However, the overall postoperative complication rate and postoperative infectious complication rate were significantly adversely affected by PBD compared with surgery without PBD. In postoperative complications analysis, ten studies including 442 patients who underwent PBD and 233 patients who had no PBD were estimated. The odds ratio (OR) for postoperative morbidity was 1.67: 95% confidence interval (CI) [1.17, 2.39]. In postoperative mortality analysis, ten studies including 422 patients who underwent PBD and 238 patients who had no PBD were estimated. The OR for postoperative mortality was 0.70: 95% CI [0.41, 1.19]. In postoperative infectious complications analysis, five studies including 134 patients who underwent PBD and 122 patients who had no PBD were estimated. The OR for infectious morbidity was 2.17: 95% CI [1.24, 3.80]. In postoperative hospital stay analysis, only three studies with 84 patients who underwent PBD and 65 patients who had no PBD were estimated; the weighted mean difference (WMD) for postoperative hospital stay was 5.37 days: 95% CI [-1.78, 12.52 days]. CONCLUSIONS This systematic review could not provide evidence for a clinical benefit of using PBD in jaundiced patients with HCCA planned for surgery. Preoperative drainage should not routinely be performed in patients with proximal bile duct cancer scheduled for surgical resection. Because of the lack of uniformity of this analysis, randomized controlled trials (RCTs) with large sample size and improved PBD techniques should be carried out to confirm our results.

Abstract
BACKGROUND Long-term survival after complete resection of hilar cholangiocarcinoma remains disappointing. The aim of this retrospective study was to assess the impact of liver optimization on postoperative outcome of hilar cholangiocarcinoma type III. MATERIALS AND METHODS In a retrospective, single-center analysis, outcomes in patients with hilar cholangiocarcinoma type III who underwent resection after preoperative liver optimization (preoperative transhepatic biliary drainage [PTBD], bile replacement, and/or portal vein embolization [PVE]) were compared with nonoptimized controls. RESULTS Of 41 patients undergoing surgery, 38 patients undergoing curative intent procedures were identified, of whom 15 underwent preoperative optimization. After PTBD, direct bilirubin decreased from 218.0 ± 184.2 to 75.9 ± 42.7 μmol/L (P = 0.03), and there was a trend toward decreased AST and ALT levels. Overall, 3- and 5-year survival rates were 47.9 ± 9.1 and 41.9 ± 9.8%. The primary endpoint, 5-year survival after surgery, was not significantly different between groups. Preoperative jaundice was identified as an independent prognostic factor for poor outcome (hazard ratio [HR] 2.12, P = 0.02). Four patients (10.5%) without preoperative optimization died of liver failure within the first 30 days postsurgery, preceded in three cases by intra-abdominal abscesses. PTBD was associated with a lower rate of postoperative intra-abdominal abscesses; however this factor was not independently predictive of higher survival. CONCLUSION Preoperative optimization of the liver in hilar cholangiocarcinoma Type III reduced the incidence of intra-abdominal abscesses, but its impact on postoperative survival remains unclear.

Abstract
INTRODUCTION Controversy exists over the preferred technique of preoperative biliary drainage (PBD) in patients with hilar cholangiocarcinoma (HCCA) requiring major liver resection. The current study compared outcomes of endoscopic biliary drainage (EBD) and percutaneous transhepatic biliary drainage (PTBD) in patients with resectable HCCA. METHODS One hundred fifteen consecutive patients were explored for HCCA between 2001 and July 2008 and assigned by initial PBD procedure to either EBD or PTBD. RESULTS Of these patients, 101 (88%) underwent PBD; 90 patients underwent EBD as primary procedure, and 11 PTBD. The technical success rate of initial drainage was 81% in the EBD versus 100% in the PTBD group (P = 0.20). Stent dislocation was similar in the EBD and PTBD groups (23% vs. 20%, P = 0.70). Infectious complications were significantly more common in the endoscopic group (48% vs. 9%, P < 0.05). Patients in the EBD group underwent more drainage procedures (2.8 vs. 1.4, P < 0.01) and had a significantly longer drainage period until laparotomy (mean 15 weeks vs. 11 weeks in the PTBD group; P < 0.05). In 30 patients, EBD was converted to PTBD due to failure of the endoscopic approach. CONCLUSIONS Preoperative percutaneous drainage could outperform endoscopic stent placement in patients with resectable HCCA, showing fewer infectious complications, using less procedures.

Abstract
BACKGROUND The purpose of the present study was to investigate the clinical association between serum bile acid level changes and liver hypertrophy in portal vein embolization (PVE). METHODS In 31 patients, the serum total bile acid level was prospectively measured before and 1, 3, 5, 7, and 14 days after right PVE. Computed tomographic volumetry was performed before and 25.0 +/- 3.6 days after PVE. RESULTS Portal vein embolization induced the liver hypertrophy with a median increase in the left lobe volume (ILV) of 165 cm(3) and a median percentage ILV (%ILV) of 29%. Compared with the pretreatment level, the serum bile acid levels significantly increased on day 3 and day 14 after PVE (p = 0.017 and p = 0.003, respectively). In patients with greater hypertrophy after PVE (ILV > 165 cm(3) and %ILV > 30%), the increases in the bile acid level on day 3 were larger than that in those with lesser hypertrophy (p = 0.008 and p = 0.002, respectively). The increase on day 3 positively correlated with the ILV and %ILV (p = 0.003 and p = 0.004, respectively). The serum bile acid levels on day 3, 5, and 7 after PVE increased in patients with %ILV > 30% but not in those with %ILV < or = 30%. CONCLUSIONS Portal vein embolization increases the serum bile acid level in patients with effective liver hypertrophy in the nonembolized lobe. The increase on day 3 is a useful predictor of effective hypertrophy of the nonembolized lobe. Thus, bile acid signaling may be important for liver regeneration post-PVE.

Abstract
In patients with malignant biliary obstruction considered suitable for surgical resection, preoperative drainage might be expected to improve surgical outcomes by restoring liver function and improving nutritional status. In practice, however, the benefits of preoperative drainage are far from clear. Studies to date have reported differing outcomes, and some have suggested that morbidity and mortality are greater in patients undergoing drainage than in those proceeding directly to surgery. The development of clinical guidelines has been limited by the lack of convincing randomized data, which in turn has led to variations in practice. This article examines the arguments for and against preoperative biliary drainage, the conflicting data on the subject, and the techniques used.

Abstract
BACKGROUND The role of preoperative biliary drainage before liver resection in jaundiced patients remains controversial. The objective of this study is to compare the perioperative outcome of liver resection for carcinoma involving the proximal bile duct in jaundiced patients with and without preoperative biliary drainage. METHODS Seventy-four consecutive jaundiced patients underwent hepatectomy for carcinoma involving the proximal bile duct from January 1989 to June 2006 and their data were retrospectively analyzed. Fourteen patients underwent biliary drainage before portal vein embolization and were excluded from the study. Thirty patients underwent biliary drainage before hepatectomy and 30 underwent liver resection without preoperative biliary drainage. All patients underwent resection of the extrahepatic bile duct. RESULTS Overall mortality and operative morbidity were similar in the two groups (3% vs. 10%, p = 0.612 and 70% vs. 63%, p = 0.583, respectively). The incidence of noninfectious complications was similar in the two groups. There was no difference in hospital stay between the two groups. Patients with preoperative biliary drainage had a significantly higher rate of infectious complications (40% vs. 17%, p = 0.044). At multivariate analysis, preoperative biliary drainage was the only independent risk factor for infectious complication in the postoperative course (RR = 4.411, 95%CI = 1.216-16.002, p = 0.024). Even considering patients with preoperative biliary drainage in whom the bilirubin level went below 5 mg/dl, the risk of infectious complications was higher compared with patients without biliary drainage (47.6% vs. 16.6%, p = 0.017). CONCLUSIONS Overall mortality and morbidity after liver resection are not improved by preoperative biliary drainage in jaundiced patients. Prehepatectomy biliary drainage increases the incidence of infectious complications.

Abstract
RATIONALE Preoperative biliary drainage (PBD) has been introduced to improve outcome after surgery in patients suffering from obstructive jaundice due to a potentially resectable proximal or distal bile duct/pancreatic head lesion. In experimental models, PBD is almost exclusively associated with beneficial results: improved liver function and nutritional status; reduction of systemic endotoxemia; cytokine release; and, as a result, an improved immune response. Mortality was significantly reduced in these animal models. Human studies show conflicting results. FINDINGS For distal obstruction, currently the "best-evidence" available clearly shows that routine PBD does not yield the appreciated improvement in postoperative morbidity and mortality in patients undergoing resection. Moreover, PBD harbors its own complications. However, most of the available data are outdated or suffer from methodological deficits. CONCLUSION The highest level of evidence for PBD to be performed in proximal obstruction, as well as over the preferred mode, is lacking but, nevertheless, assimilated in the treatment algorithm for many centers. Logistics and waiting lists, although sometimes inevitable, could be factors that might influence the decision to opt for PBD, as well as an extended diagnostic workup with laparoscopy (on indication) or scheduled preoperative chemotherapy.

Abstract
Three types of preoperative biliary drainage (BD): percutaneous transhepatic (PTBD), endoscopic (EBD), and endoscopic nasobiliary (ENBD) can be indicated before resection of cholangiocarcinoma. However, three randomized controlled trials (RCTs) have revealed that preoperative PTBD does not improve perioperative results. Other RCTs have revealed that preoperative EBD for malignant obstructive jaundice has no demonstrable benefit and after EBD for hilar cholangiocarcinoma there are highly developed infectious complications. Most patients with distal cholangiocarcinoma undergo pancreatoduodenectomy (PD) without preoperative BD. However, no RCTs have been performed to clarify the safety of major hepatectomy without preoperative BD for cholestatic patients with hilar cholangiocarcinoma. Furthermore, preoperative intrahepatic segmental cholangitis is a prognostic factor in the outcome of major hepatectomy for biliary cancer. Preoperative BD has another purpose in the preoperative management of patients with hilar cholangiocarcinoma. Selective cholangiography via ENBD and/or PTBD catheters provides precise information about the complicated segmental anatomy of the intrahepatic bile ducts and extent of cancer along the separated segmental bile ducts, which contributes toward designing a type of resective procedure. RCTs in biliary cancer patients undergoing major hepatectomy have revealed that bile replacement during external biliary drainage and perioperative synbiotic treatment can prevent postoperative infectious complications. Although preoperative EBD increases the risk of cholangitis, major hepatectomy combined with preoperative biliary drainage, preferably PTBD and/or ENBD, followed by portal vein embolization has been established as a safer management strategy for perihilar cholangiocarcinoma.

Abstract
The clinical application of portal vein embolization (PVE) has contributed to improving the postoperative outcome of hilar cholangiocarcinoma. The enlarged nonembolized lobe after PVE protects the patient from postoperative hepatic failure, due to the increased functional reserve, and shortens the hospital stay. Although numerous reports have shown beneficial effects of PVE on postoperative outcome after extended hepatectomy, no randomized controlled study has been performed so far. It is urgent to establish a "gold standard" of PVE, because the indications, approach to the portal vein, types of embolic materials, and methods used to evaluate the function of the future liver remnant are variable among institutions. The indications and procedures of PVE for hilar cholangiocarcinoma may be different from those for hepatocellular carcinoma or colorectal metastasis, because, in many patients with hilar cholangiocarcinoma, biliary cancer is associated with biliary obstruction and cholangitis. This review article summarizes the contribution of PVE to the outcome of postoperative management in patients with hilar cholangiocarcinoma needing extended hepatectomy. We also describe our PVE procedure, which has been established from our experience of more than 240 cases of biliary cancer. Furthermore, the drawbacks of PVE, which may reduce the pool of candidates for surgery, are also discussed.

Abstract
BACKGROUND Portal vein embolization (PVE) improves outcome following major hepatectomy, and basic studies have presented evidence related to the mechanisms responsible for hepatic regeneration. Hemodynamic changes following PVE are similar to, but slightly different from, those of partial hepatectomy (PH) because arterial flow to the embolized lobe is preserved. However, the process of hepatic regeneration is essentially the same after both PVE and PH. A number of mediators are involved in PVE or PH-induced hepatic regeneration. These include inflammatory cytokines, vasoregulators, growth factors, eicosanoids, and various hormones. These mediators activate a complex network of signal transduction that promotes hepatic regeneration. A variety of conditions have been shown to modulate the function of these mediators and inhibit regeneration. These include biliary obstruction, diabetes, chronic ethanol consumption, malnutrition, gender, aging, and infection. CONCLUSION Optimizing these factors, where possible, before PVE or PH, is essential to maximize hypertrophy of the liver. A fuller understanding of hepatic physiology and pathophysiology following PVE or PH may lead to greater functional capacity of the remaining liver and extend the indications for hepatectomy in patients who require large liver volume resection.

Abstract
The regenerative capacity of the liver is an important factor following liver surgery. The dramatic change in portal venous flow, due to either portal vein embolization or partial hepatectomy, induces a rapid change in liver volume. In response to these stresses, hepatocytes are primed, through the release of inflammatory cytokines, to increase the expression of immediate early genes and increase the activation of transcriptional factors. The primed hepatocytes then respond to growth factors, including hepatocyte growth factor, epidermal growth factor, and transforming growth factor-alpha. Several pathologic conditions have been shown to inhibit hepatic regeneration. These include diabetes mellitus, malnutrition, aging, infection, chronic ethanol consumption, and biliary obstruction. Impaired hepatic regeneration in the setting of biliary obstruction is an especially serious problem because it can be a major determinant in not considering surgical treatment. The mechanism responsible for impaired hepatic regeneration in patients with biliary obstruction includes decreased portal venous flow, attenuated production of liver proliferation-associated factors, an increased rate of apoptosis, and lack of enterohepatic circulation. Restoring these factors may lead to an improvement in regeneration in a cholestatic liver following portal vein embolization or partial hepatectomy. This review article summarizes the current understanding of the mechanism of hepatic regeneration, with particular emphasis on that in the cholestatic liver.

Abstract
OBJECTIVE To investigate the effect of bile replacement following percutaneous transhepatic biliary drainage, ie, external drainage, on intestinal permeability, integrity, and microflora in a clinical setting. SUMMARY BACKGROUND DATA Several authors have reported that internal biliary drainage is superior to external drainage. However, it is unclear whether bile replacement following external drainage is beneficial. METHODS Twenty-five patients with biliary cancer underwent percutaneous transhepatic biliary drainage (PTBD) as a part of presurgical management. All externally drained bile was replaced either per os or by administration through a nasoduodenal tube. The interval between PTBD and the beginning of bile replacement was 21.3 +/- 19.7 days, and the length of bile replacement was 20.7 +/- 9.6 days. The lactulose-mannitol test, measurement of serum diamine oxidase (DAO) activity, and analyses of fecal microflora and organic acids were performed before and after bile replacement. RESULTS The volume of externally drained bile varied widely from patient to patient, ranging from 220 +/- 106 mL/d to 1616 +/- 394 mL/d (mean, 714 +/- 346 mL/d). Biliary concentrations of bile acids, cholesterol, and phospholipids increased significantly after bile replacement. The lactulose-mannitol (L/M) ratio decreased from 0.063 +/- 0.060 before bile replacement to 0.038 +/- 0.032 after bile replacement (P < 0.05). Serum DAO activity increased from 3.9 +/- 1.4 U/L before bile replacement to 5.1 +/- 1.6 U/L after bile replacement (P < 0.005), and the magnitude of change in serum DAO activity correlated with the length of bile replacement (r = 0.483, P < 0.05). Neither the L/M ratios nor serum DAO activities before bile replacement correlated with the interval between PTBD and the beginning of bile replacement. Fecal microflora and organic acids were unchanged. CONCLUSION Impaired intestinal barrier function does not recover by PTBD without bile replacement. Bile replacement during external biliary drainage can restore the intestinal barrier function in patients with biliary obstruction, primarily due to repair of physical damage to the intestinal mucosa. Our results support the hypothesis that bile replacement during external drainage is beneficial.

Abstract
BACKGROUND The role of leukocytes in obstructive jaundice is obscure and the effect of relieving cholestasis on leukocyte function is unclear. We postulated that cholestasis affects systemic polymorphonuclear leukocyte function by deranging phagocytosis and hydrogen peroxide release and the leukocyte dysfunction is reversible by internal and external biliary drainage. MATERIALS AND METHODS Sixty male Sprague Dawley rats were randomly assigned to four groups: obstructive jaundice (OJ), sham operation (SH), OJ with internal drainage (ID), and OJ with external drainage (ED). The phagocytic functions of neutrophils and monocytes in whole blood were measured with flow cytometry using fluorescent microspheres. Intracellular hydrogen peroxide production by leukocytes was assessed with flow cytometry using dihydrorhodamine-123 as probes. RESULTS Leukocyte count and percentage of monocytes in rats with OJ was significantly increased compared with SH rats (P < 0.001). These elevations could be reversed by both ID and ED method (P < 0.001). The phagocytic function of neutrophils and monocytes was significantly depressed in OJ rats compared with that in SH rats (P < 0.001). After relief of the OJ, the suppressed phagocytic function of neutrophils and monocytes was completely improved in ID rats (ID versus OJ, P < 0.001), but only partially reversed in ED rats. The hydrogen peroxide production by monocytes and lymphocytes was significantly increased in OJ rats (P < 0.05). ID reversed the increased hydrogen peroxide generation (P < 0.05), but ED only partially did. CONCLUSIONS In our rodent model of biliary obstruction, deranged phagocytosis, and hydrogen peroxide generation by leukocytes was found. Internal drainage is superior to external drainage for reversal of the distorted leukocyte function.

Abstract
Recently, T cells were classified into two categories: intrathymic T cells (ITCs; thymus-derived T cells) and extrathymic T cells (ETCs). ETC, localized in the liver and intestinal intraepithelium (IE), play an important immunologic role in the suppressed condition of T-cell development in the thymus. Given the fact that complications of surgery in patients with obstructive jaundice are often related to immunosuppression in the gut-liver circulation, we attempted to investigate the changes in the proportion of ETCs in mice with obstructive jaundice. Three mice models were prepared ( n = 10 per group): sham group with simple laparotomy; ligation group with common bile duct ligation; deoxycholic acid (DCA) group with an oral intake of DCA as a model of the presence of bile salts in the gut lumen. In each model, total mononuclear cells (MNCs), ITCs in the thymus, and ETCs in the liver and IE were counted using monoclonal antibodies in conjunction with a two-color immunofluorescence test by flow cytometry. In the ligation group the number of MNCs was reduced in the thymus and IE, and only those in the IE recovered after oral intake of DCA. A decrease of ITCs in the thymus and the increase in ETCs in the liver and IE occurred simultaneously during the early phase of biliary obstruction. At day 7 after biliary obstruction, ETCs in the livers of the DCA and ligation groups decreased to nearly the level in the sham group. However, on day 7 the ETCs in the IE remained significantly higher in the DCA group than in the ligation group. These results suggested that ETCs can act in place of ITCs at an early phase of obstructive jaundice, and the presence of bile in the gut lumen may be associated with the consumption of ETCs in the IE, a reaction that may bring about improved immunoreactivity.

Abstract
INTRODUCTION Cholestasis activates nuclear factor kappa B (NFkappaB), which is involved in both hepatocyte proliferation and apoptosis, depending on the cellular microenvironment. We hypothesized that NFkappaB inhibition would decrease hepatocyte proliferation and potentiate hepatocyte apoptosis in a rat model of extrahepatic biliary obstruction. AIM To determine if NFkappaB inhibition concomitantly decreases hepatocyte proliferation and increases apoptosis in obstructive jaundice. MATERIALS AND METHODS Male Sprague-Dawley rats underwent either sham operation or bile-duct ligation (BDL) combined with portal vein injection of vehicle or 6 x 10(9) particles of an adenovirus carrying either the control luciferase or the IkappaB super-repressor (AdIkappaBSR) transgenes. Liver was harvested 3, 5, and 7 days after sham operation or BDL, and immunohistochemistry for proliferating cell nuclear antigen and terminal dUTP nick end-labeling was performed for detection of DNA synthesis and apoptosis, respectively. RESULTS Increased serum total bilirubin and hematoxylin and eosin-stained liver sections confirmed cholestasis in BDL animals. Western blot analysis demonstrated IkappaBSR protein expression in AdIkappaBSR-infected animals only. At day 7, NFkappaB inhibition decreased hepatocyte DNA synthesis in BDL rats compared to both adenovirus carrying the control luciferase and vehicle-treated controls. Apoptosis was increased in BDL vehicle-treated animals compared to sham-operation animals, but NFkappaB inhibition did not alter hepatocyte apoptosis in the BDL group. CONCLUSION In obstructive cholestasis, NFkappaB is required for hepatocyte proliferation, but does not augment apoptosis.

Abstract
Necessity of preoperative biliary drainage for patients with obstructive jaundice is still controversial. We recently reported that liver regeneration after major hepatectomy was better restored in a rat model of obstructive jaundice with preoperative internal biliary drainage than that without biliary drainage or with external biliary drainage. The aim of this study was to investigate the differences in biliary lipid excretion after hepatectomy in obstructive jaundiced rats with or without preoperative internal or external biliary drainage. After bile duct ligation for 7 days, rats were randomly divided into the three groups; obstructive jaundice-hepatectomy (OJ-Hx), internal biliary drainage-hepatectomy (ID-Hx), and external biliary drainage-hepatectomy (ED-Hx) groups. 70% hepatectomy and internal biliary drainage were carried out 7 days after biliary decompression in the latter two groups and without biliary decompression in the OJ-Hx group. On the day of and on days 1, 2, 3 and 7 after hepatectomy, the liver weight, DNA synthesis rate, biliary lipids excretion rates, and bile acid composition were determined. In the ID-Hx group, the DNA synthesis rate and relative liver weight were significantly higher than those of the OJ-Hx and ED-Hx groups. The excretion rates of biliary lipids were disturbed in the ED-Hx group compared with those in the ID-Hx group and the values in the OJ-Hx group were in-between the ID-Hx and ED-Hx group. The liver regeneration rate was significantly correlated with bile flow and excretion rates of biliary lipids. The maintenance of enterohepatic circulation of biliary lipids before hepatectomy may be important for the liver regeneration.

Abstract
BACKGROUND The importance of bile in liver regeneration after hepatectomy is unknown, although we have recently shown that preoperative internal biliary drainage is superior to external biliary drainage for liver regeneration in obstructive jaundiced rats. This study examined the hypothesis that the presence or absence of bile in the intestinal tract modulates cyclins and cyclin-dependent kinases after hepatectomy in rats. METHODS In male Wistar rats, bile was drained externally (ED group) or into the duodenum (ID group) for 7 days before 70% hepatectomy. Relative liver weight, DNA synthesis rate, and proliferating cell nuclear antigen labeling index were determined at the time of hepatectomy (day 0) and on days 1, 3, and 7 after hepatectomy. Posthepatectomy expressions of cyclin D1 and E and of cyclin D1- and E-associated kinases were serially analyzed. Hepatic function tests were performed. RESULTS No significant difference in liver function was found between the 2 groups at hepatectomy except for the lower albumin level in the ED group. The relative liver weight was lower in the ED group than in the ID group on day 3 after hepatectomy (ED, 2.58% +/- 0.06%; ID, 2.84% +/- 0.08%; P <.05). Both the DNA synthesis rate and proliferating cell nuclear antigen labeling index in the ED group (77 +/- 36 disintegrations per minute/microg DNA and 8.3% +/- 1.9%, respectively) were lower than those in the ID group (262 +/- 50 disintegrations per minute/microg DNA and 21.6% +/- 5.6%, respectively) on day 1 after hepatectomy (P <.05, respectively). Cyclin D1-associated kinase activity and cyclin D1 expression were not significantly different between the 2 groups. Cyclin E-associated kinase activity was lower in the ED group than in the ID group at 18 hours after hepatectomy (ED, 84% +/- 17%; ID, 146% +/- 28% of the value at 0 hour in the ID group; P <.05), although expressions of cyclin E and p27 binding to cyclin E were not significantly different between the 2 groups. CONCLUSIONS These results suggest that the absence of bile in the intestine delays liver regeneration associated with cyclin E-associated kinase inactivation after hepatectomy.

Abstract
BACKGROUND Major hepatic resection in patients with unrelieved obstructive jaundice carries an increased risk of postoperative liver failure. We hypothesized that cholestasis induces hepatocyte apoptosis and impairs hepatic regeneration by inhibiting up-regulation of the known immediate-early response genes, nuclear factor kappa B (NF-kappaB) and activating protein-1 (AP-1). The aim of this study was to determine whether the immediate-early gene response in hepatic regeneration remains intact in extrahepatic cholestasis. METHODS Eight-week-old BALB/c mice underwent either sham operation (SO) or common bile duct ligation (BDL). Two-thirds partial hepatectomy (PH) was performed at 4 and 7 days, with remnant liver harvested 0, 15, 30, or 60 minutes after PH. Serum analysis for markers of cholestasis and histopathology was obtained. Proliferating cell nuclear antigen and terminal deoxyuridine triphosphate nick end labeling (TUNEL) immunohistochemistry for detection of DNA synthesis and apoptosis, respectively, was performed 4, 7, or 10 days after SO or BDL. Liver samples from 0, 15, 30, or 60 minutes after PH were analyzed for NF-kappaB and AP-1 DNA binding activity by using electrophoretic mobility shift assays. RESULTS Increased serum bilirubin level and hematoxylin-eosin-stained liver sections confirmed cholestasis in BDL mice. BDL induced marked DNA synthesis and hepatocyte apoptosis in prehepatectomy liver at both 4 and 7 days. Substantially higher basal levels of both NF-kappaB and AP-1 binding activity were present in BDL compared with SO mice. Fold induction of NF-kappaB and AP-1, however, was similar between BDL and SO mice. Cholestasis induced hepatocyte DNA synthesis and apoptosis. Basal NF-kappaB and AP-1 DNA binding activity was increased in BDL mice, but fold induction of these immediate-early genes did not differ from controls. CONCLUSIONS Although basal NF-kappaB and AP-1 DNA binding is increased in cholestasis, the immediate-early gene response to PH remains intact in BDL mice.

Abstract
BACKGROUND Biliary obstruction impairs liver function although the pathophysiological mechanism is incompletely understood. AIMS The aim of this study was to examine serial changes in liver metabolism in patients with obstructive jaundice using image guided in vivo 31-phosphorus magnetic resonance spectroscopy ((31)P MRS). This technique allows repeated and non-invasive assay of organ energy metabolism and phospholipid biochemistry. PATIENTS We studied 10 patients presenting with obstructive jaundice secondary to extrahepatic localised malignancy. There were eight men and two women, median age 72 years (range 54-94), six with cholangiocarcinoma (all Bismuth type 1) and four with carcinoma of the head of the pancreas. Ten healthy volunteers (median age 24 years (range 21-26)) were studied for comparison. METHODS Hepatic metabolism in jaundiced patients was measured by (31)P MRS at presentation and again after a one week period of biliary drainage. Conventional liver function tests were also recorded. RESULTS Compared with controls, liver spectra from jaundiced patients contained an excess of phosphomonoester (PME) metabolites (PME/total phosphate median 10.3% (interquartile range 8.7-11.5) in controls, 15.4% (13.1-17.7) in jaundiced cases; p<0.01). Biliary decompression was achieved in all patients (five with internal stents and five by external drainage catheters), and plasma biochemistry improved predictably (bilirubin 176 micromol/l (158-351) at presentation, 110 micromol/l (42-241) after drainage for one week; p<0.01). Enhancement of hepatic energy status, measured by the ratio of adenosine triphosphate (ATP) to inorganic phosphate (Pi), was observed in all cases after relief of biliary obstruction (ATP/Pi 1.4 (1.17-1.69) at presentation, 1.97 (1.4-2.48) after drainage; p<0.01) and was independent of the route of bile drainage. Hepatic phosphodiester (PDE) content was decreased after relief of obstruction (PDE/total phosphate 25.2% (20.5-27.4) at presentation, 19.8% (16.6-24.5) after drainage; p<0.01). This change was probably due to a reduction in the contribution from bile contents to this resonance as a strong PDE signal was also detectable in spectra obtained from separate bile specimens. CONCLUSIONS Obstructive jaundice produces alterations in liver phosphoester biochemistry, most likely reflecting disturbances in phospholipid metabolism. Relief of biliary obstruction is associated with a measurable increase in hepatic energy status. Bile may contribute to the phosphodiester signal of the 31-phosphorus liver spectrum and changes in these resonances must therefore be interpreted with caution and in relation to the clinical situation. Monitoring of liver metabolism by (31)P MRS may allow clinicians to refine the selection and timing of therapeutic options in jaundiced patients.

Abstract
BACKGROUND The aim of this study was to evaluate serial changes in liver volume after major hepatectomy for biliary cancer and to elucidate clinical factors influencing liver regeneration. METHODS Serial changes in liver volume were determined, using computed tomography, in 81 patients with biliary cancer who underwent right hepatic lobectomy or more extensive liver resection with or without portal vein resection and/or pancreatoduodenectomy. Possible factors influencing liver regeneration were evaluated by univariate and multivariate analyses. RESULTS The remnant mean(s.d.) liver volume was 41(8) per cent straight after hepatectomy. This increased rapidly to 59(9) per cent within 2 weeks, then increased more slowly, finally reaching a plateau at 74(12) per cent about 1 year after hepatectomy. The regeneration rate within the first 2 weeks was 16(8) cm3/day and was not related to the extent of posthepatectomy liver dysfunction. On multivariate analysis, the extent of liver resection (P < 0.001), body surface area (P = 0.02), combined portal vein resection (P = 0.024) and preoperative portal vein embolization (P = 0.047) were significantly associated with the liver regeneration rate within the first 2 weeks. In addition, body surface area (P < 0.001) and liver function expressed as plasma clearance rate of indocyanine green (P = 0.01) were significant determinants of final liver volume 1 year after hepatectomy. CONCLUSION The liver regenerates rapidly in the first 2 weeks after major hepatectomy for biliary cancer. This early regeneration is influenced by four clinical factors. Thereafter, liver regeneration progresses slowly and stops when the liver is three-quarters of its original volume, approximately 6 months to 1 year after hepatectomy.

Abstract
CCAAT/enhancer-binding protein (C/EBP)-alpha stabilizes p21(WAF1), whereas activating protein-1 (AP-1) and C/EBP-beta enhance cyclin D1 and cyclin E expression, respectively, during the progress of liver regeneration. In this study, we investigated the differences in the transcription factors and cell cycle regulators between obstructive jaundiced and control rats before and after hepatectomy accompanied with a release of biliary obstruction by internal biliary drainage. The expressions and activities of C/EBP-alpha and -beta were significantly decreased in the jaundiced group concomitant with the significantly lower cyclin E expression after hepatectomy than in the controls. The activities of AP-1, cyclin D1 and p21(WAF1) were not significantly different between the two groups. These results suggest that obstructive jaundice inhibits hepatic expression and activity of C/EBP, resulting in the impaired cyclin E expression that is partly responsible for the cell cycle dysfunction after hepatectomy.

Abstract
BACKGROUND Surgery for patients with malignant obstructive jaundice carries high morbidity and mortality rates. Preoperative biliary drainage (PBD) has been used in an attempt to improve the outcome in these patients. AIM To review the evidence in the literature on whether PBD improves postoperative morbidity and mortality in obstructive jaundice patients. MEHOD: Using Medline a literature search was performed for papers published in English from January 1980 to October 2000, using the text words 'obstructive jaundice', 'preoperative', 'drainage' and 'stent'. All retrieved papers which reported experimental or clinical observations relevant to the study aim were carefully analysed and the findings are summarised in this review. RESULTS AND CONCLUSION There is no evidence in the literature to support the view that routine PBD improves postoperative morbidity and mortality in patients with obstructive jaundice undergoing resection. PBD has its own complications that cancel out its benefits. However, PBD could be beneficial in patients presenting with sepsis, coagulation abnormalities or malnutrition.

Abstract
BACKGROUND Correlation of the hepatic adenosine triphosphate (ATP) level with indocyanine green (ICG) excretion into bile was examined in patients with obstructive jaundice after the relief of hyperbilirubinemia by preoperative percutaneous transhepatic biliary drainage (PTBD). METHODS Patients with complete bile duct obstruction, the mean serum total bilirubin concentration being 13.6 +/- 8.5 (SD) mg/dL, underwent PTBD prior to surgery. Within a few days before surgery when the mean serum total bilirubin level decreased to 1.2 mg/dL, ICG (0.5 mg/kg) was intravenously injected, and the whole bile was collected at 1-hour intervals for 5 hours. The ICG concentration in bile, bile flow rate, amount of ICG excreted in bile, and biliary ICG excretion rate as percentage of the injected dose were determined. At the time of surgery, a small liver tissue sample was obtained immediately after laparotomy without any ischemic procedures, and ATP concentrations were determined. Results of hepatic ATP levels were correlated with laboratory and clinical determinations. RESULTS The bile flow rate was essentially constant during the 5-hour period, the mean value being 21 mL/hour. The ICG concentrations in bile gradually increased, reached the maximal level in 3 hour, and declined thereafter. The biliary ICG excretion rate for 5 hours was 40% +/- 18% of its injected dose. The biliary ICG excretion rate and amount of ICG excreted in bile for 5 hours significantly (P <0.05) correlated with the hepatic ATP level. The decline index of serum bilirubin during PTBD was also correlated with the hepatic ATP level. The serum ICG retention rate, bile flow rate, maximal ICG concentration in bile, and other liver function tests including serum albumin and cholinesterase levels did not correlate with the hepatic ATP level. CONCLUSIONS Both the amount of and excretion rate of ICG in bile reflect the hepatic ATP level. Determination of biliary ICG excretion contributes to precise evaluation of hepatic energy status before surgery in patients with obstructive jaundice.
