The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.

Complications of cholecystectomy: risks of the laparoscopic approach and protective effects of operative cholangiography: a population-based study. (1/364)

BACKGROUND: Previous studies suggest that laparoscopic cholecystectomy (LC) is associated with an increased risk of intraoperative injury involving the bile ducts, bowel, and vascular structures compared with open cholecystectomy (OC). Population-based studies are required to estimate the magnitude of the increased risk, to determine whether this is changing over time, and to identify ways by which this might be reduced. METHODS: Suspected cases of intraoperative injury associated with cholecystectomy in Western Australia in the period 1988 to 1994 were identified from routinely collected hospital statistical records and lists of persons undergoing postoperative endoscopic retrograde cholangiopancreatography. The case records of suspect cases were reviewed to confirm the nature and site of injury. Ordinal logistic regression was used to estimate the risk of injury associated with LC compared with OC after adjusting for confounding factors. RESULTS: After the introduction of LC in 1991, the proportion of all cholecystectomy cases with intraoperative injury increased from 0.67% in 1988-90 to 1.33% in 1993-94. Similar relative increases were observed in bile duct injuries, major bile leaks, and other injuries to bowel or vascular structures. Increases in intraoperative injury were observed in both LC and OC. After adjustment for age, gender, hospital type, severity of disease, intraoperative cholangiography, and calendar period, the odds ratio for intraoperative injury in LC compared with OC was 1.79. Operative cholangiography significantly reduced the risk of injury. CONCLUSION: Operative cholangiography has a protective effect for complications of cholecystectomy. Compared with OC, LC carries a nearly twofold higher risk of major bile, vascular, and bowel complications. Further study is required to determine the extent to which potentially preventable factors contribute to this risk.  (+info)

Helical computed tomographic cholangiography versus endosonography for suspected bile duct stones: a prospective blinded study in non-jaundiced patients. (2/364)

BACKGROUND: Helical computed tomography performed after intravenous administration of a cholangiographic contrast material (HCT-cholangiography) may be useful for detecting bile duct stones in non-jaundiced patients. However, this method has never been compared with other non-invasive biliary imaging tests. AIMS: To compare prospectively HCT-cholangiography and endosonography (EUS) in a group of non-jaundiced patients with suspected bile duct stones. METHODS: Fifty two subjects underwent both HCT-cholangiography and EUS. Endoscopic retrograde cholangiography (ERCP), with or without instrumental bile duct exploration, served as a reference method, and was successful in all but two patients. RESULTS: Thirty four patients (68%) were found to have choledocholithiasis at ERCP. The sensitivity for HCT-cholangiography in stone detection was 85%, specificity 88%, and accuracy 86%. For EUS the sensitivity was 91%, specificity 100%, and accuracy 94%. The differences were not significant. No serious complications occurred with either method. CONCLUSIONS: HCT-cholangiography and EUS are safe and comparably accurate methods for detecting bile duct stones in non-jaundiced patients.  (+info)

Cholangiographic features in the diagnosis and management of obstructive icteric type hepatocellular carcinoma. (3/364)

In 11 years and 3 months, 2,037 patients with HCC were seen and 48 patients (2.4%) were diagnosed to have obstructive icteric type HCC. Five patients were terminally ill and were not investigated further. Forty three patients were initially investigated by endoscopic retrograde cholangiography (ERC) or percutaneous transhepatic cholangiogram (PTC) and classified as having obstructive icteric type 1, 2, or 3 HCC based on the cholangiographic findings. The obstruction in type 1 HCC was due to intraluminal tumour casts and/or tumour fragments obstructing the hepatic ductal confluence or common bile duct, while intraluminal blood clots, from haemobilia, filling the biliary tree was the cause in type 2 HCC. The pathology in type 3 HCC was extraluminal obstruction by extensive tumour encasement of the intra-hepatic biliary ductal system and/or extrinsic compression of the hepatic and common bile ducts by tumour(s) and/or malignant lymph nodes. At the initial ERC/PTC, 10 patients (5 resected, 50%) had obstructive icteric type 1 and 23 patients (0 resected) had obstructive icteric type 3 HCC. Of the 10 patients initially classified according to cholangiography to have obstructive icteric type 2 HCC, subsequent investigations revealed that 6 patients had type 1 HCC (4 resectable,67%) and 4 patients had type 3 HCC (0 resectable). The classification of the obstructive icteric type HCC into types 1, 2, and 3, based on the initial cholangiographic appearances has simplified and rationalized our management strategy for this condition.  (+info)

Posterior hepatic duct injury during laparoscopic cholecystectomy finally necessitating hepatic resection: case report. (4/364)

A case of bile duct injury during laparoscopic cholecystectomy finally necessitating right hepatic lobectomy is reported to re-emphasize the importance of preoperative and intraoperative assessment of the biliary tree. A 47-year-old Japanese woman underwent laparoscopic cholecystectomy for cholecystolithiasis. On postoperative day 5, fever and right hypochondralgia developed, and CT revealed fluid collection at the right hypochondrium. Percutaneous drainage was performed, and subsequent fistulography revealed a communication of the cystic cavity with the right posterior bile duct, which suggested injury of the aberrant hepatic duct. Conservative therapy, including the adaptation of fibrin glue, was performed, but closure of the fistula and cavity was not obtainable. Finally, a right hepatic lobectomy was performed four months after cholecystectomy. In this case, endoscopic retrograde cholangiopancreatography was unsuccessful preoperatively, and intraoperative cholangiography was not done. This case report re-emphasizes that the preoperative and intraoperative examination of the biliary tree is mandatory to avoid bile duct injury.  (+info)

Scintigraphic detection of bile leak and follow-up in a post-cholecystectomy patient with recognition of tail sign. (5/364)

Early detection of site and extent of biliary tract disruption can significantly reduce mortality and morbidity in a postoperative biliary leak. We report a case in whom extent and location of post surgical biliary leak was detected with the help of 99mTc BULIDA cholescintigraphy and showed a good correlation with "T" tube cholangiography. Cholescintigraphy was also useful in assessing the follow up of this patient. We conclude that 99mTc BULIDA cholescintigraphy is a non-invasive, safe, simple and sensitive procedure in the detection of the site, extent of the leak and in follow up of the postoperative biliary leak.  (+info)

The importance of intraoperative cholangiography during laparoscopic cholecystectomy. (6/364)

Laparoscopic cholecystectomy (LC) using an electrosurgery energy source was successfully performed in 59 (95%) out of 62 selected patients. The procedures were performed by different surgical teams at Trakya University, Medical Fakulty, in the department of General Surgery and the Karl-Franzens-University School of Medicine, in the department of General Surgery. Cholangiography was routine at Karl Franzens University and selective at Trakya University. Laparoscopic intraoperative cholangiography (IOC) was performed in 48 (81.3%) patients, and open IOC was performed in 3 patients. Two patients had common duct stones; one of which was unsuspected preoperatively. These cases underwent endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic papillotomy (EP). One patient had a choledocal tumor, unsuspected preoperatively. Anatomical anomalies were not identified. Cholangiography could not be performed in one case in which there was no suspected pathology. ERCP was performed on one patient 30 days after being discharged because of acute cholangitis. In this case, residual stones were identified in the choledocus. Four patients underwent open cholecystectomy because of tumor, unidentified cystic duct or common bile duct pathology that could not be visualized on the cholangiogram. Our study suggests that cholangiography performed via the cystic duct before any structures are divided can prevent the most serious complication of laparoscopic cholecystectomy--common duct injury. We recommend that cholangiography be attempted on all patients undergoing LC.  (+info)

Laparoscopic cholecystectomy and appendectomy in situs inversus totalis. (7/364)

Situs inversus totalis is an uncommon anatomic anomaly that complicates diagnosis and management of acute abdominal pain. Expedient diagnosis of common intraperitoneal disease processes such as biliary colic, acute appendicitis and diverticulitis is often delayed as a result of seemingly incongruous physical findings. We present the case of a young woman with prior emergency room visits for complaints of a vague left upper quadrant abdominal pain. An ultrasound performed on her third presentation revealed visceral situs inversus with cholelithiasis and dilated intra- and extrahepatic biliary ducts. Standard laparoscopic cholecystectomy and cholangiography with a mirror-image surgical approach was performed successfully and without complication.  (+info)

Changing strategies in diagnosis and management of hilar cholangiocarcinoma. (8/364)

Hilar cholangiocarcinoma is one of the most difficult tumors to stage and treat. This study aims to evaluate (1) the best diagnostic imaging, (2) the usefulness of preoperative biliary drainage, (3) the resectability rate, and (4) the results of palliative treatments and surgical resection. Seventy-six patients with hilar cholangiocarcinoma with a mean age of 64 +/- 11 years were treated at our institution from 1989 to 1999. Patients were studied preoperatively using ultrasound, computed tomography (CT), and percutaneous cholangiography or magnetic resonance cholangiography. Forty-eight patients (63%) underwent palliative treatment. Twenty-eight patients underwent surgical curative therapy; 20 resections and 8 orthotopic liver transplantations (OLTs). Percutaneous transhepatic cholangiography was performed in 18 of 28 patients (64%), and magnetic resonance cholangiography in 5 patients; both methods were equally effective in establishing tumoral invasion of the biliary ducts. Five patients did not undergo either diagnostic modality. Excluding the patients who underwent OLT, no significant differences were found in surgical mortality (1 v 2 patients) or postoperative morbidity (100% v 66%) for patients with and without preoperative biliary drainage. The postoperative mortality rate was 11% (3 of 28 patients). The overall resectability rate was 37%. Mean survival in the surgical and palliative groups was 35 and 6 months, respectively (P <.0001). Patients who underwent OLT had a better 5-year survival rate than those treated by tumor resection (36% v 21%; P =.02). Combined chemotherapy and radiotherapy apparently did not provide a significant survival benefit. Helical CT and magnetic resonance cholangiography are useful techniques to delineate tumor extent and rule out vascular invasion and lymph node or liver metastases. No clear conclusions regarding preoperative drainage can be drawn from this study. A high resectability rate (37%) is feasible with major hepatectomy.  (+info)

MRC is emerging as the latest imaging technology to evaluate the biliary tree. This noninvasive method is used to visualize these structures without using a contrast agent. Because the magnetic resonance images can be directly acquired in any plane, 3-dimensional representation of biliary tract anatomy and pathology can be accurately obtained. Patients receive no radiation exposure and unlike other imaging modalities, such as ultrasonography, ERCP, or percutaneous transhepatic cholangiography, MRC does not rely on operator skill. The limitations of MRC include imaging artifact caused by metallic surgical clips and air in the biliary tree. Additionally, MRC does depend on technology that requires a multicoil device for better spatial resolution, which is currently not widely available (1). Should MRC be used in the routine diagnosis of biliary tract disease, and where does it fit in the diagnostic work-up? Although Soto and colleagues should be commended for their efforts, it is difficult to ...

Malignant hilar tumours are usually unresectable at the time of diagnosis.6 7 Although resection offers the only chance of cure, the five year survival rate after potentially curative resection for hilar cholangiocarcinoma has been reported to be from 0 to 22%,2 16 and the resectability rate from 20 to 30%6 16; there is no indication for surgery in patients with hilar metastases. Hence palliative non-surgical treatment of obstructive jaundice is often the main treatment for most patients at the time of diagnosis, as radical excision of hilar tumours is precluded by the patients general condition, tumour extension into both lobes of the liver, portal vein, or hepatic artery tumour encasement, or distant metastasis.. When communication persists between the right and left hepatic ducts (Bismuths type I), the endoscopic insertion of a single stent is admittedly the best way to ensure drainage, although some type I stricture patients may be candidates for surgical resection or bypass. When the ...

A surgical marker clip and method for enhancing the safe performance of a cholangiography and cholecystectomy is disclosed. The clips are configured to frictionally engage the outer surface of the duct and are retained in place by light clamping force without damaging the duct. Placement of the clips allows a physician to visually isolate the common bile duct from the cystic duct during laparoscopic procedures which reduces bile duct injury typically caused by misidentification or visual misperception of the anatomy during the procedure.

We report a case of cholecysto-colonic fistula in a female patient, due to bile duct lithiasis. Cholelithiasis is the most common cause of fistula (in more than 90% of the cases) [1]. Cholelithiasis could cause either repeated episodes of acute cholecystitis/cholangitis or asymptomatic chronic calculous cholecystitis [1]. The chronological events that lead to the fistula include gallbladder inflammation, adhesions between intestines and gallbladder, mechanical erosion by gallstones and gangrenous changes of both the gallbladder and the adjacent colon wall.. Enterobiliary fistulae most commonly result from calculus cholecystitis, but can also occur occasionally following carcinoma of the gallbladder where the necrotic tumour perforates into the adjacent duodenum or colon, or both [2]. Due to its proximity, the duodenum is the most common site of intestines involved.. Biliary ileus is defined as a mechanical intestinal obstruction due to a gallstone lodging in the intestinal lumen.

BRIC Pancreatic and Biliary Stent Procedures Outlook to 2025 - Endoscopic Retrograde Cholangiopancreatography (ERCP) Pancreatic and Biliary Stenting Procedures and Percutaneous Transhepatic Cholangiography (PTC) Biliary Stenting Procedures
Different approaches to the treatment of bile duct injuries. According to the existing literature, endoscopic and/or radiologic management of BDI is feasible, whenever theres a continuity in bile duct and not a complete transection. These approaches can include an endoscopic retrograde cholangiography to drain bile ducts after sphincterotomy or placement of endoprosthesis [1]. Approach by an endoscopic retrograde cholangiography allows biliary stenting or balloon dilatation, considered to be the first-line treatment in some referral centres. Usually the placement of a 7 - 8.5 French single plastic stent is the first step in a series of endoscopic rehabilitation protocol. If a single stent is not effective, placement of multiple stents or a large-diameter stent can be selected [2]. Patients undergoing endoscopic stent treatment has shown a safe and favourable long term outcome, although no consensus has been reached regarding placement of one single stent alone or sequential insertion of ...

HPB Surgery is a peer-reviewed, Open Access journal that offers ready access to important developments in the field of HPB surgery and associated disciplines. We aim to publish fresh experimental and clinical work across the spectrum of HPB disease, while concentrating on those conditions for which surgical treatment - not necessarily an actual operation - is a common option. Thus diabetes mellitus and hepatitis, for example, might belong more appropriately elsewhere, though not if the paper should concern pancreatic transplantation or virally-induced hepatoma.
The lack of excretion may also constitute valuable information. Patients without excretion are likely to have either a total occlusion of the main bile duct/choledochus or severely impaired hepatocyte function. The bilirubin concentration, if not already considerably elevated, is likely to increase in these patients. In this study, the lack of excretion could be explained by the final diagnosis in all patients (Table 3).. The protein-binding characteristics essential for biliary contrast media increase the risk of adverse reactions [11, 15]. In a previously published review of the literature on the frequency of adverse reactions in examinations with short injection time (,10 min), the pooled number of adverse events was three times higher (16% vs. 5%) than after infusion (,30 min) of the same amount of contrast media [11]. The frequency of adverse events of iotroxate (Biliscopin®) at infusion has been reported to be as high as 3.4%, with a pooled frequency of 1.9% (Table 4). It has been ...

TY - JOUR. T1 - Carcinoma of the extrahepatic bile ducts. AU - Wei, T. C.. AU - Wei, P. L.. AU - Yu, S. C.. AU - Lee, P. H.. AU - Hsu, S. C.. PY - 1995. Y1 - 1995. N2 - Fifty-two patients with carcinoma of the extrahepatic bile ducts were reviewed. There were 28 men and 24 women whose ages ranged from 31 to 78 years, with a mean age of 58 years. Symptoms, signs and laboratory results were primarily the result of bile duct obstruction. The most valuable diagnostic procedures were percutaneous transhepatic cholangiography and endoscopic retrograde cholangiopancreatography. In 28 patients the tumor was located in the upper, 9 in the middle and 12 in the lower common bile duct. In the other three patients the tumor was diffuse. The resectability rate was 21.2% (11/52). Of the remaining patients, 10 (19.2%) had T-tube drainage, 5 (9.6%) had biliary digestive anastomosis, 18 (34.6%) had percutaneous transhepatic biliary drainage and 8 (15.4%) had biopsy only. The histologic diagnosis was sclerosing in ...

Y1 - 1983/1/1. N2 - Cholangiograms of 86 patients with primary sclerosing cholangitis (PSC) were compared with those of 82 patients with primary bile duct carcinoma and 16 with primary biliary cirrhosis. Multifocal strictures involving both intra- and extra-hepatic bile ducts were most common in PSC; they were diffusely distributed, short, and annular, alternating with normal or slightly dilated segments to produce a beaded appearance. Very short, band-like strictures occurred in 18 patients; 9 also had diverticulum-like outpouchings. Fourteen patients had diverticula without band strictures. Both findings appear to be specific for PSC. Inflammatory bowel disease was seen in 57 patients (66%), who could not be distinguished cholangiographically from other PSC patients. Of 40 patients with adequate ...

AU - McGahan, John P. PY - 2013/4. Y1 - 2013/4. N2 - Purpose: To determine if excreted contrast is consistently visualized in the gallbladder and duodenum after a 30-minute delay using gadoxetate disodium-enhanced MRI in patients without hepatobiliary disease. Materials and Methods: Twenty-two patients without evidence of liver or biliary disease underwent gadoxetate disodium-enhanced magnetic resonance imaging (MRI) from February 17, 2009 through October 3, 2011. The mean age was 45 years (range 25-72). T1-weighted hepatobiliary phase images at 5, 10, 20, and 30 minutes after contrast injection were reviewed in consensus by two radiologists to determine the delay at which enhancement of the gallbladder and duodenum first occurred. Results: Thirteen of 22 (59.1%) patients demonstrated duodenal filling ...
This study aimed to evaluate the radiologists ability to identify excreted gadoxetate disodium within the gallbladder on CT scan. Thirty three healthy adults underwent imaging of the liver during work-up for potential liver donation. Three patients had undergone prior cholecystectomy and therefore were excluded. Imaging consisted of gadoxetate disodium-enhanced magnetic resonance cholangiography (MRC) and multiphase contrast-enhanced CT scan of the abdomen and pelvis. Two fellowship-trained abdominal imaging radiologists, who were blinded to the MRC images and the contrast agent used during MRC, independently reviewed the CT scans of the 30 patients that were included. The scans were evaluated for the presence or absence of abnormal hyperdensity within the gallbladder. Three patients did not receive intravenous gadoxetate disodium, 4 patients had their MRC after the CT scan, and 1 patient had the CT scans 5 days following the MRC. Twenty two patients had the CT scan within 24 h following the gadoxetate
Autoimmune hepatitis (AIH) may have an atypical serum alkaline phosphatase elevation, antimitochondrial antibodies, histologic features of bile duct injury/loss, or cholangiographic findings of focal biliary strictures and dilations. These manifestations characterize the overlap syndromes. Patients can be classified as having AIH with features of primary biliary cholangitis, primary sclerosing cholangitis, or a cholestatic syndrome. The gold standard of diagnosis is clinical judgment. Histologic evaluation is a major diagnostic component. Treatment is based on algorithms; outcomes vary depending on the predominant disease component. Combination therapy has been the principal recommendation.

Results:. It was observed that the presence of dilatation of the biliary tract or choledocholithiasis in the ultrasonography was four and eight times increased risk of perioperative cholangiography for positive choledocholithiasis, respectively. For each unit increased in serum alkaline phosphatase was 0.3% increased the risk of perioperative cholangiography for positive choledocholithiasis. In the presence of dilatation of the bile ducts in the ultrasonography was four times greater risk of positive magnetic resonance cholangiopancreatography for choledocholithiasis. In the presence of pancreatitis these patients had five times higher risk of positive magnetic resonance cholangiopancreatography for choledocholithiasis. On the positive magnetic resonance cholangiopancreatography presence to choledocholithiasis was 104 times greater of positive perioperative cholangiography for choledocholithiasis. ...
From November 1994 to March 1996, 150 patients treated by laparoscopic cholecystectomy were included in a prospective study, in order to compare intraoperative cholangiography and laparoscopic ultrasound. The biliary tree was successively explored by the two methods in the systematic detection of common bile duct stones. The feasibility of laparoscopic ultrasound was 100 per cent. Cholangiography was performed in only 125 cases (83 per cent). The duration of the laparoscopic ultrasound exam was significantly shorter (11.6 vs 17.6 minutes, p = 0.0001). In this study, common bile duct stones were found in 14 cases (9 per cent). The detection rates with laparoscopic ultrasound and intraoperative cholangiography were similar. For laparoscopic ultrasound, sensitivity was 80 per cent and specificity was 99 per cent, versus 78 per cent and 97 per cent for cholangiography, respectively. The combination of the 2 examinations had a 100 per cent sensitivity and specificity. Laparoscopic ultrasound failed to

The effectiveness of MRC based on overall cost, however, remains unknown. Our aim was to determine the average cost per correct diagnosis using MRC or ERCP as the initial testing strategy for the diagnosis of PSC. A decision analysis model was constructed employing diagnostic test parameters prospectively determined among 73 patients with clinically suspected biliary disease. ERCP was performed within 24 hours after MRC. Cost data were derived from average Medicare reimbursement fee schedules. ...

In the period of the study we observed 68 patients with CBD stones, 37 were older than 65 years: 15 (40.5%) males and 22 (59.5%) female, with a mean age of 76.45 years (range 65 -93). Twelve (32.4%) patients were treated by LC and intraoperative clearance of the CBD by the RV. ERCP was performed in 22 (59.5%) patients: 8(21.6%) previous cholecistectomized and 14(63.6%) who still had their gallbladder, but with high anaesthetic risk. In one patient the RV technique failed and laparoscopic choledocotomy was performed and a T-tube left in situ, but after 3 week trans-Kher cholangiography showed residual stones, so the patient was submitted to ERCP. In other two cases only LC was performed because the papilla of Vater was difficult to approach. The length of hospital stay was on average 7 days.
