Cystic duct stones in postcholecystectomy Mirizzi syndrome - A novel endoscopic treatment.

Mirizzi syndrome is a rare type of cholelithiasis, and the main treatment is still surgery. The development of endoscopic technology has made surgeons more active in the management of rare diseases of the biliary tract and pancreas. Here we report that our center applied the new endoscopic method to treat a Mirizzi patient with residual cystic neck duct stones after laparoscopic cholecystectomy.

Intraoperative detection of the remnant cystic duct during robot-assisted surgery using near-infrared fluorescence imaging: a case report.

BACKGROUND: Post cholecystectomy syndrome is characterized as recurrence of symptoms as experienced before cholecystectomy. In rare cases, a remnant cystic duct is causing these symptoms and occasionally surgical resection is performed. During surgery, visualization of the biliary ducts could be difficult due to inflammation and dense adhesions. CASE PRESENTATION: In this article, we presented a 36-year old woman with post-cholecystectomy syndrome in which we evaluated the feasibility of near-infrared (NIR) fluorescence imaging using indocyanine green (ICG) for visualization of the remnant cystic and common bile duct during robot-assisted surgery. Intraoperative visualization of the remnant biliary duct and other important structures was feasible, and resection of the remnant cystic duct was successfully performed under fluorescence guidance, without any complications. CONCLUSIONS: NIR fluorescence imaging of the biliary ducts using ICG does not prolong the operating time, and could potentially decrease the operation time in difficult procedures, because of easy and fast detection of the biliary tract. Furthermore, it is a non-hazardous and non-invasive technique, as it does not require use of radiation and cannot cause bile duct injury. This case illustrated that ICG NIR fluorescence imaging during difficult robot-assisted surgical procedures of the bile ducts is effective and therefore highly recommended.

Post-laparoscopic cholecystectomy Mirizzi syndrome induced by polymeric surgical clips: a case report and review of the literature.

BACKGROUND: Laparoscopic cholecystectomy is the gold standard treatment of gallbladder disease. Post-cholecystectomy syndrome is a severe postoperative complication which can be caused by multiple mechanisms and can present with multiple disorders. The wide use of laparoscopy induces the need to understand more clearly the presentation and pathophysiology of this syndrome. Post-cholecystectomy Mirizzi syndrome is one form of this syndrome and, according to literature, this is the first report that clearly describes it. CASE PRESENTATION: We describe the case of a 62-year-old Greek woman who underwent laparoscopic cholecystectomy because of gallstone disease. A few days after surgery, post-cholecystectomy syndrome gradually developed with mild bilirubin increase in association with epigastric pain, nausea, and vomiting. After performing ultrasound, magnetic resonance cholangiopancreatography, and endoscopic retrograde cholangiopancreatography, we conducted a second laparoscopic surgery to manage the obstruction, which was converted to open surgery because of the remaining inflammation from the post-endoscopic retrograde cholangiopancreatography acute pancreatitis. Four polymeric laparoscopic clips were removed because they were identified as the cause of her post-cholecystectomy syndrome. She had a quick recovery without further complications. CONCLUSIONS: Postoperative Mirizzi syndrome induced by the migration of polymer laparoscopic clips is a rare (only one case referring to polymeric clips has been published in the literature) but a well-identified complication of laparoscopic cholecystectomy which can confuse the diagnostic and therapeutic field requiring simultaneous immediate management.

Utility of endoscopic ultrasound to diagnose remnant stones in symptomatic patients after cholecystectomy.

BACKGROUND AND STUDY AIMS: Stones in the cystic duct stump (CDS) or gallbladder remnant after cholecystectomy are difficult to identify. The aim of this study was to evaluate the utility of endoscopic ultrasound (EUS) in the diagnosis of stones in the CDS or gallbladder remnant in patients with postcholecystectomy syndrome. METHODS: A prospective study was conducted between January 2011 and December 2012 in consecutive patients with pancreaticobiliary-type pain or acute pancreatitis (n = 112) following cholecystectomy. Diagnostic modalities including EUS were used to diagnose the cause of postcholecystectomy syndrome. RESULTS: A total of 11 patients (10 %) were found to have stones in the gallbladder remnant (n = 8), CDS (n = 2), or both (n = 1). In eight patients, EUS was the first imaging procedure to make the diagnosis. Seven patients agreed to undergo repeat surgery, and six of them remained free of symptoms postoperatively after a median follow-up period of 4 months (range 1 - 13 months). CONCLUSION: EUS may be an important procedure to consider in the study of patients with symptoms after cholecystectomy, as the diagnosis of residual stones is frequently missed by other imaging modalities.

Surgical and endoscopic management of remnant cystic duct lithiasis after cholecystectomy--a case series.

INTRODUCTION: Postcholecystectomy syndrome (PCS) as a result of remnant cystic duct lithiasis (RCDL), or gallstones within the cystic duct after cholecystectomy, can cause persistent or recurrent symptoms after cholecystectomy. STUDY DESIGN: A retrospective descriptive analysis was performed for all patients with RDCL at a single institution between 2001 and 2012. Details of presentation, diagnosis, and surgical and endoscopic treatments, and outcomes were collected and analyzed. RESULTS: Twelve patients with RCDL were identified. The interval between cholecystectomy to RCDL discovery was 34.2 months (range 0.5-168 months). On a standard liver enzyme panel, 75% of patients had derangements in ≥1 indices, with the most common single laboratory test abnormality occurring in gamma-glutamyl transferase (GGT) (80%). Eight operative reports noted that the cystic duct was noticeably dilated at the time of cholecystectomy. Two patients developed a cystic duct leak (Strasberg type A bile duct injury) postoperatively, which was managed nonoperatively. Six cases of RCDL required surgery, and six were managed endoscopically. CONCLUSION: RCDL is a potential cause of postcholecystectomy syndrome, but the true incidence is unknown. Laboratory analysis and imaging are helpful in establishing the diagnosis of RCDL. Endoscopic therapy has a role in the treatment of RCDL, but surgical excision of the remnant cystic duct lithiasis may be required.

[Forced resection of the liver right lobe in the patient with cholelithiasis].

There is a case of cholelithic illness complicated by cholangiolithiasis, the treatment of which resulted in resection of the right hepatic lobe.

[Pathogenetic and diagnostic aspects of postcholecystectomy syndrome].

In the review up-to-date information about postcholecystectomy syndrome was adduced. The main underlying pathogenetic links of different functional disturbs and organic pathology were considered. Necessity of this nosologic unit common diagnostic algorithm elaboration was proved by own and literature data analysing.

Biliary ascariasis as a cause of post-cholecystectomy syndrome in an endemic area.

BACKGROUND: Post-cholecystectomy syndrome encompasses numerous biliary, pancreatic and other entities. Biliary ascariasis is a common cause of adult biliary disease in an endemic area. Post-cholecystectomy biliary ascariasis, a cause of post- cholecystectomy syndrome although not yet defined is frequently seen in this part of the world. METHOD: Between Jan. 1990 and Jan. 2001, 104 cases of post-cholecystectomy biliary ascariasis were seen. Ultrasonography was found to be an excellent tool for diagnosing and monitoring of the worms inside the biliary tract. Endoscopic retrograde cholangiopancreatography had both diagnostic and therapeutic value. RESULTS: The majority (68.2%) of patients responded to conservative treatment. Surgical treatment was advocated in 18.2%, which included 2 patients with liver abscesses. Endoscopic extraction of worms was successful in 48.2%. CONCLUSION: Post-cholecystectomy biliary ascariasis as a cause of post-cholecystectomy syndrome needs to be included in the list of causes for post-cholecystectomy syndrome. Although the majority of patients respond to conservative treatment but endoscopic extraction or surgical intervention may be needed. Routine deworming of patients undergoing cholecystectomy both preoperatively and postoperatively should be done in all patients in endemic areas of ascariasis. Although this entity is rare in Europe and United States, due to population migration and increased travel, it is necessary for surgeons in these countries to be aware of this condition.

Relation of coffee, green tea, and caffeine intake to gallstone disease in middle-aged Japanese men.

A possible protective effect of coffee or caffeine intake in the formation of gallstones has been suggested in some epidemiological studies. We examined the relation of coffee, green tea, and caffeine intake to gallstone disease in middle-aged Japanese men, distinguishing known gallstones from unknown diagnosed gallstones. Study subjects were 174 cases of gallstones as determined by ultrasonography, 104 cases of postcholecystectomy, and 6889 controls of normal gallbladder in the total of 7637 men who received a health examination at four hospitals of the Self-Defense Forces (SDF). Of the 174 cases of prevalent gallstones, 50 had been aware of having gallstones. Previously diagnosed gallstones and postcholecystectomy were combined as known gallstone disease. The consumption of coffee and green tea was ascertained by a self-administered questionnaire, and caffeine intake was estimated. Statistical adjustment was done for body mass index, smoking, alcohol use, rank in the SDF, and hospital. Coffee and caffeine intake were associated each with a statistically significant increase in the prevalence odds of known gallstone disease, but unrelated to newly diagnosed gallstones. Adjusted odds ratios of known gallstone disease were 1.7 (95% confidence interval [CI] 1.1-2.8) for coffee consumption of five cups or more per day vs. no consumption and 2.2 (95% CI: 1.3-3.7) for caffeine intake of 300 mg/day or more vs. less than 100 mg/day. The consumption of green-tea showed no material association with either unknown gallstones or known gallstone disease. The findings do not support a hypothesis that coffee drinking may be protective against gallstone formation.

Oral contrast-enhanced three-dimensional helical-CT cholangiography: clinical applications.

Our objective was to define the possibility of using oral-contrast-enhanced helical CT for the assessment of patients with cholecystolithiasis and of cholecystectomized symptomatic patients. Twenty-seven patients with cholecystolithiasis and 20 with a painful abdominal symptomatology after cholecystectomy (12 laparoscopic and 8 laparotomic) were recruited for this study. Cholangio-CT was performed 12-14 h after oral administration of 6 g of hyopanoic acid. The acquired data were then transferred to a second workstation and 3D reconstruction of the biliary tract was obtained. In all the cases the extrahepatic bile ducts were recognizable. Seven patients had no gallbladder opacification: CT images showed in 3 cases an infundibular stone and in 4 cases sclero-atrophic gallbladder. The intrahepatic bile ducts were visible in 21 of 27 patients with lithiasis and in 14 of 20 cholecystectomized patients. In 5 cholecystectomized patients cholangio-CT demonstrated the presence of residual choledochal or intrahepatic stones. In 3 cholecystectomized patients 3D reconstruction allowed identification of a long and winding stump of the cystic duct. Cholangio-CT is a non-invasive method to evaluate the biliary tract in patients who cannot be subjected to cholangio-MR, or as a preliminary to endoscopic retrograde cholangiopancreatography in cases of doubtful diagnosis after US and cholangio-MR.

Obstructive jaundice due to internal herniation: a case report and review of the literature.

A 45-year-old man was suffering from abdominal pain and vomiting. He was admitted to our hospital with a diagnosis of ileus and obstructive jaundice. He had undergone Roux-en-Y anastomosis for choledocholithiasis 14 years earlier. A computed tomography scan revealed a dilated afferent loop and dilated intrahepatic bile duct. Upper gastrointestinal examination with contrast medium and percutaneous transhepatic cholangiography showed a high intestinal obstruction around the jejunojejunal anastomosis. The patient underwent laparotomy based on a diagnosis of obstructive jaundice due to ileus. During the operation, he was found to have internal herniation of the small bowel through a rent in the mesentery around the Roux-en-Y anastomosis for choledochojejunostomy. The hernia was reduced, and bowel resection was performed due to stenosis of the afferent loop. Jejunojejunal anastomosis was re-performed and the defect in the mesocolon was closed. Internal herniation after Roux-en-Y anastomosis is a rare sequela, but it should be recognized that this complication can occur after Roux-en-Y anastomosis. For prevention of internal herniation around the Roux-en-Y limb, secure closing of the mesenteric defects is important.

[Long-term results of benign bile duct strictures after treatment with pedicled jejunal patches]. / Langzeitergebnisse nach Behandlung benigner Gallengangsstrikturen mit gestieltem Jejunumstreifen.

Benign strictures of the common bile duct after surgery or due to gallstones may lead to obstruction and derangement of bile drainage in the extrahepatic biliary system. Although the treatment of choice in these situations is the endoscopic dilatation, in some cases with stenosis of a long segment of the bile duct a partial replacement with a vascularised jejunal patch may be possible and useful. To our knowledge, there are no reports on long-term results of the procedure. We describe the course, the surgical technique and long-term results of four patients with a jejunal patch reconstruction of the common bile duct. Ten years after surgery there were no radiologic or laboratory signs of a restenosis of the common bile duct.

Bronchobiliary fistula: principles of management.

Bronchobiliary fistula is an uncommon entity. Recently, we encountered 2 patients with this problem. Both were treated successfully with resection of the involved pulmonary tissue and interposition of viable tissue between the lung and the fistulous tract. This approach, although invasive, provided a rapid resolution of the patients' problem.

Endoscopic management of sump syndrome after choledochoduodenostomy: retrospective analysis of 30 cases.

BACKGROUND: Side-to-side choledochoduodenostomy is a frequently performed operation. Postoperative biliary "sump syndrome" is infrequent, a complication for which endoscopic sphincterotomy is regarded as the treatment of choice. METHODS: We retrospectively analyzed 30 cases of sump syndrome and describe the symptoms, the delay before the appearance of symptoms, laboratory abnormalities, the nature of the biliary obstruction, and the outcome of endoscopic sphincterotomy including its efficiency and complications. RESULTS: The median clinical latency was 5 years (range 1 month to 28 years), the median delay between surgery and diagnosis was 6 years (range 1 month to 28 years). Fourteen patients had abdominal pain with fever, 5 had isolated abdominal pain, 4 had post-prandial pain, 4 had hepatic abscesses, and 3 had acute pancreatitis. Liver function tests were abnormal in 79%. During endoscopic retrograde cholangiopancreatography, food debris was identified in 18 patients in the biliary sump, biliary calculi in 10 patients, and a mixture of food and calculi in 2 patients. All patients underwent endoscopic sphincterotomy without complication. Recurrence during a median follow-up of 36 months (range 3 months to 11 years) was not observed. CONCLUSIONS: Sump syndrome most often becomes symptomatic only after a long delay. Abdominal pain with fever was the most frequent symptom. Liver function tests were abnormal in the majority of patients. Food debris was the most frequent cause. Endoscopic sphincterotomy appeared to be a safe, reliable treatment.

Endoscopic nasobiliary drainage for treating bile leak after laparoscopic cholecystectomy.

BACKGROUND/AIMS: Bile leaks are common complications of laparoscopic cholecystectomy. We evaluated the diagnosis and endoscopic treatment of bile leaks. METHODOLOGY: A total of 436 patients underwent laparoscopic cholecystectomy with infrahepatic drainage. We performed immediate endoscopic retrograde cholangiopancreatography (ERCP) on all patients with bile discharge from an infrahepatic drain, and treated bile leaks which were not due to a major ductal injury by endoscopic nasobiliary drainage (ENBD) without endoscopic sphincterotomy (ES). RESULTS: Ten patients developed bile leaks which were recognized within 18 hours of operation. ERCP, on post-operative day 1 or 2, showed a bile leak from the cystic duct (9 patients) or the liver bed (1 patient). All patients underwent ENBD. Only 1 patient, who had a retained stone, had ES. In all patients, the bile leak resolved promptly and both the infrahepatic and nasobiliary drains were removed within 6 days of cholecystectomy. All patients were asymptomatic at a mean follow-up of 30 months. CONCLUSIONS: Routine placement of an infrahepatic drain is recommended for the early detection of bile leaks. Bile leaks can be successfully treated by prompt ENBD without ES.

[Post-cholecystectomy syndrome: hepatobiliary scintigraphy and cholangiopancreatography with magnetic resonance in 5 consecutive patients. Comparison of results and integrated diagnosis]. / Sindrome post-colecistectomia: studio mediante scintigrafia epatobiliare e colangiopancreatografia con Risonanza Magnetica in cinque pazienti consecutivi. Confronto dei risultati e diagnosi integrata.

PURPOSE: To investigate the clinical effectiveness of combined hepatobiliary scintigraphy (HBS) and MR-cholangiopancreatography (MRCP) studies in the postcholecystectomy syndrome. MATERIAL AND METHODS: June 1997, to February 1998, we examined with HBS and MRCP five women, three of them submitted to surgical and two to laparoscopic cholecystectomy. All patients had biliary pain but no changes in cholestasis and liver function blood parameters. After at least 4 hours' fasting HBS was performed dynamically, for one hour, injecting a 185 MBq 99mTc-mebrofenin bolus i.v. A fatty meal was given at the end of the basal test and serial static images were acquired till complete biliary washout. RESULTS: MRCP was normal in one case while in the others it showed biliary tree dilation, severe stricture of the distal common bile duct (CBD) and marked enlargement of the remnant cystic duct (RCD), which lodged a 6-mm stone in one patient. Pancreatic ducts were regular. HBS showed delayed biliary transit in all patients, which was however completed within 3 hours of injection, favored by the fatty meal. The RCD was not injected in three cases. Finally, HBS detected an early liver dysfunction in three cases. DISCUSSION: HBS and MRCP allow to evaluate the biliary tree function and anatomy, respectively, adding further data on liver function and pancreatic duct morphology. We detected associated functional and organic biliary alterations which were the likely cause of postcholecystectomy pain, such as severe spasm in Oddi's sphincter, nonpatent enlarged RCD and RCD stones. Moreover, HBS detected an early liver dysfunction in three cases. In conclusion, combined HBS and MRCP studies make a noninvasive, simple and accurate diagnostic approach in postcholecystectomy syndrome and for the screening of patients needing prompt surgical treatment.

Three-dimensional helical computed tomography with intravenous cholangiography for sclerosing cholangitis manifested as postcholecystectomy symptom.

A 46-year-old woman who had upper abdominal pain 10 years after cholecystectomy, and who had incidental sclerosing cholangitis (SC), was investigated by three-dimensional helical computed tomographic (3-DHCT) cholangiography with contrast medium, because endoscopic retrograde cholangiography (ERC) was unsuccessful and a second ERC was not permitted by the patient. The cholangiogram demonstrated annular strictures of the bilateral hepatic duct at the confluence of the common hepatic duct, and dilatation of the left intrahepatic biliary duct. Although we could not clarify the cause of the biliary tract deformity at the time of the 3-DHCT, the tentative diagnosis of postcholecystectomy deformity of the biliary tree led to successful treatment by right liver lobectomy and hepaticojejunostomy. Histologic findings were compatible with SC. From this experience and the literature, we suggest that 3-DHCT cholangiography with contrast medium can contribute to the preoperative diagnosis of morphological changes in the biliary tree in patients with postcholecystectomy symptoms.
