Successful treatment of recurrent cholangitis complicating liver transplantation by Roux-en-Y limb lengthening

Short limb in biliary tract reconstruction: A retrospective study of living donor liver transplantation in children with biliary atresia

Roux-en-Y cholangiojejunostomy is a standard procedure for biliary reconstruction in pediatric living donor liver transplantation (LDLT). However, there is uncertainty on whether the adult standard of Roux branch limb is suitable for pediatric LDLT and its impact on postoperative biliary complications (BC). This study aimed to explore the effect of the short Roux limb and standard limb on pediatric LDLT biliary reconstruction. According to the length of the Roux limb, 168 LDLT children were divided into the routine limb group (n = 108) and the short limb group (n = 60). The incidences of postoperative biliary tract complications between the 2 groups were compared retrospectively. The mean Roux limb length in the short limb group was significantly shorter than that in the routine limb group group (P < .01). There were significant differences in age, height, and weight between the 2 groups (P < .01). However, there were no significant differences in graft-to-recipient weight ratio, intraoperative blood loss, cold ischemia time, and operation time between the 2 groups (P > .01). Moreover, postoperative BC, including refluxing cholangitis, were similar between the 2 groups (P = .876). Furthermore, the history of Kasai surgery, the history of postoperative RC of Kasai, and whether or not the Roux limb was reconstructed had no significant effect on the occurrence of postoperative RC. There was no significant difference in postoperative BC between the short limb and the routine limb in children with living donor liver transplantation.

Successful treatment of postoperative nonobstructive recurrent cholangitis by tract conversion surgery after total pancreatectomy: a case report

BACKGROUND

Postoperative cholangitis is a complication of biliary reconstruction during hepatobiliary pancreatic surgery. Most cases are associated with anastomotic stenosis, but there are also cases of cholangitis without stenosis, and treatment can be difficult, especially in patients with recurrent symptoms. In this report, we describe a case of repeated nonobstructive cholangitis in a patient after total pancreatectomy, in which a good outcome was obtained after performing tract conversion surgery.

CASE PRESENTATION

The patient was a 75-year-old man. He underwent total pancreatectomy for stage IIA cancer of the pancreatic body, hepaticojejunostomy via the posterior colonic route, gastrojejunostomy and Braun anastomosis via the anterior colonic route using the Billroth II method. The patient had a good postoperative course and was receiving adjuvant chemotherapy on an outpatient basis, but he developed his first episode of cholangitis 4 months after surgery. Although conservative treatment with antimicrobial agents was successful, the patient continued to have recurrent biliary cholangitis and was repeatedly admitted and discharged from the hospital. Since stenosis at the anastomosis was suspected, endoscopic observation of the anastomosis was performed using small bowel endoscopy for close examination, but no apparent stenosis was observed. Small bowel imaging indicated a possible influx of contrast medium into the bile duct, and reflux due to food residue was suspected as the cause of cholangitis. Since conservative treatment alone did not suppress the flare-up of symptoms, the decision was made to perform tract conversion surgery for curative purposes. The afferent loop was cut midstream, and jejunojejunostomy was performed downstream. The postoperative course was good, and the patient was discharged on the 10th day after surgery. He is currently an outpatient and has been free of cholangitis symptoms for 4 years without cancer recurrence.

CONCLUSIONS

Although the diagnosis of nonobstructive retrograde cholangitis can be difficult, surgical treatment should be considered in patients with recurrent symptoms and refractory treatment.

Evaluation and management of biliary complications after pediatric liver transplantation: pearls and pitfalls for percutaneous techniques

In pediatric liver transplantation, bile duct complications occur with a greater incidence than vascular anastomotic dysfunction and represent a major source of morbidity and mortality. While surgical re-anastomosis can reduce the need for retransplantation, interventional radiology offers minimally invasive and graft-saving therapies. The combination of small patient size and prevailing Roux-en-Y biliary enteric anastomotic techniques makes endoscopic retrograde cholangiopancreatography difficult if not impossible. Expertise in percutaneous management is therefore imperative. This article describes post-surgical anatomy, pathophysiology and noninvasive imaging of biliary complications. We review percutaneous techniques, focusing heavily on biliary access and interventions for reduced liver grafts. Subsequently we review the results and adverse events of these procedures and describe conditions that masquerade as biliary obstruction.

Antireflux Status Post Roux-en-Y anastomosis: An Experimental Study for Optimal Antireflux Technique

Background

Roux-en-Y hepaticojejunostomy has been a gold standard to establish biliary-enteric anastomosis for various surgical indications, but associated with variable incidences of cholangitis. This experimental study was conducted to report a modification in Roux-en-Y anastomosis for possible better alternative to provide antireflux procedure after Roux-en-Y biliary-enteric anastomosis with the aim to minimize the possibility of reflux and its consequences.

Materials and Methods

For experimental study, the required fresh segment of Lamb's small intestine was procured. Three sets of Roux-en-Y anastomosis were created for each experiment. In set 1, there was simple Roux-en-Y anastomosis. In set 2, Roux-en-Y anastomosis along with 4-5 cm long spur between the hepatic and duodenal limbs was created. In set 3, in addition to Roux-en-Y with creation of spur, additional antireflux mechanism was created at the junction of upper two-third and lower one-third of the hepatic limb. Saline mixed contrast was infused by infusion pump to raise the intraluminal pressure to more than 10 cm of H₂O. X-ray was taken at that time.

Results

In set 1, all preparations demonstrated reflux of contrast in the hepatic limb. The set 2 also demonstrated the same findings of 100% reflux in the hepatic limb. In set 3, No reflux was observed in 8 (80%) preparations while remaining 2 (20%) preparations reveal partial reflux.

Conclusion

This experimental study suggests that the provision of spur and additional valve may be able to decrease the possibility of reflux in Roux-en-Y biliary-enteric anastomosis.

Recurrent cholangitis by biliary stasis due to non-obstructive afferent loop syndrome after pylorus-preserving pancreatoduodenectomy: report of a case

We report a 71-year-old man who had undergone pylorus-preserving pancreatoduodenectomy (PPPD) using PPPD-IV reconstruction for cholangiocarcinoma. For 6 years thereafter, he had suffered recurrent cholangitis, and also a right liver abscess (S5/8), which required percutaneous drainage at 9 years after PPPD. At 16 years after PPPD, he had been admitted to the other hospital because of acute purulent cholangitis. Although medical treatment resolved the cholangitis, the patient was referred to our hospital because of dilatation of the intrahepatic biliary duct (B2). Peroral double-balloon enteroscopy revealed that the diameter of the hepaticojejunostomy anastomosis was 12 mm, and cholangiography detected intrahepatic stones. Lithotripsy was performed using a basket catheter. At 1 year after lithotripsy procedure, the patient is doing well. Hepatobiliary scintigraphy at 60 minutes after intravenous injection demonstrated that deposit of the tracer still remained in the upper afferent loop jejunum. Therefore, we considered that the recurrent cholangitis, liver abscess, and intrahepatic lithiasis have been caused by biliary stasis due to nonobstructive afferent loop syndrome. Biliary retention due to nonobstructive afferent loop syndrome may cause recurrent cholangitis or liver abscess after hepaticojejunostomy, and double-balloon enteroscopy and hepatobiliary scintigraphy are useful for the diagnosis of nonobstructive afferent loop syndrome.

SPECIALTY

Gastroenterology and Hepatology.

OBJECTIVE

Unusual clinical course.

BACKGROUND

Cholangitis may result from biliary obstruction (e.g., biliary or anastomotic stenosis, or foreign bodies) or occur in the presence of normal biliary drainage. Although reflux of intestinal contents into the biliary tree after hepaticojejunostomy appears to be a rare complication, it is important to emphasize that there are few available surgical therapeutic techniques.

CASE REPORT

A 74-year-old woman presented to our hospital after 17 years of episodes of cholangitis. The patient had undergone a pancreatoduodenectomy (Whipple procedure) 18 years earlier due to pancreatic adenocarcinoma. The reconstruction was achieved through the sequential placement of pancreatic, biliary, and retrocolic gastric anastomosis into the same jejunal loop. The postoperative course was uneventful and the patient received adjuvant chemotherapy. Approximately 6 months after the initial operation, the patient started having episodes of cholangitis. Over the next 17 years she experienced several febrile episodes presumed to be secondary to cholangitis. A computing tomography (CT) scan of the abdomen revealed intrahepatic bile ducts partially filled with orally administered contrast material (Gastrografin). Magnetic resonance cholangiopancreatography (MRCP) showed dilatation of the left intrahepatic bile ducts. A percutaneous transhepatic cholangiography showed that the bilioenteric anastomosis was normal, without stenosis. Based on these findings, a diagnosis of a short loop between the hepaticojejunostomy and the gastrojejunostomy permitting the reflux of intestinal juice into the biliary tree was made. During the re-operation, a new hepaticojejunal anastomosis in a 100-cm long Roux-en-Y loop was performed to prevent the reflux of the intestinal fluid into the biliary tree. The patient was discharged on postoperative day 10. One year after the second procedure, the patient enjoys good health and has been free of fever and abdominal pain and has not received any antibiotic therapy.

CONCLUSIONS

Lengthening the efferent Roux-en-Y limb should be considered as a therapeutic option when treating a patient with recurrent episodes of cholangitis after hepaticojejunostomy.

Bacterial biliary tract infections in liver transplant recipients

PURPOSE OF REVIEW

The purpose of this study is to provide an overview of bacterial biliary tract infections in liver transplant recipients with a focus on pathogenesis and conservative treatment strategies.

RECENT FINDINGS

The development of interventional endoscopic and radiologic interventions has improved the outcome of conservative treatments for bile tract strictures and bilomas. However, recent data show an important rise of infections with multidrug-resistant (MDR) pathogens in liver transplant recipients.

SUMMARY

Both recurrent cholangitis and infected bilomas are bacterial biliary tract infections in liver transplant recipients responsible for significant morbidity and graft loss, which require a multidisciplinary approach. Risk factors for biliary tract strictures and bilomas formation have recently been identified. With the improved outcome of a conservative management including prolonged and/or recurrent antibiotic treatments, the risk of selecting resistant pathogens is increased. There is an urgent need to develop new strategies to reduce the risk of secondary infections by MDR isolates in liver transplant recipients.

Duct-to-duct reconstruction in liver transplantation for primary sclerosing cholangitis is associated with fewer biliary complications in comparison with hepaticojejunostomy

There is no consensus on the preferred type of biliary reconstruction for patients undergoing orthotopic liver transplantation (OLT) for primary sclerosing cholangitis (PSC). The aim of this study was to compare long-term outcomes after OLT for PSC using either duct-to-duct anastomosis or Roux-en-Y hepaticojejunostomy for biliary reconstruction. In a consecutive series of 98 adult patients undergoing OLT for PSC, 45 underwent duct-to-duct reconstruction, and 53 underwent Roux-en-Y biliary reconstruction. The median follow-up was 8.2 years (interquartile range = 3.9-14.5 years). The outcomes of the 2 groups were compared. There were no significant differences in patient demographics or general surgical variables between the groups. The overall patient and graft survival rates were similar for the 2 groups. The incidence of biliary strictures and biliary leakage within the first year after transplantation did not differ between the 2 groups. However, significantly more patients in the Roux-en-Y group suffered at least 1 episode of cholangitis within the first year (9% in the duct-to-duct group versus 25% in the Roux-en-Y group, P = 0.04). In addition, Roux-en-Y reconstruction was associated with a significantly higher rate of late-onset (>1 year after transplantation) nonanastomotic biliary strictures (NAS) in comparison with duct-to-duct reconstruction (24% versus 7% at 5 years and 30% versus 7% at 10 years, P = 0.01). In conclusion, duct-to-duct biliary reconstruction in patients with PSC is associated with lower rates of posttransplant cholangitis and late-onset NAS in comparison with Roux-en-Y hepaticojejunostomy. If technically and anatomically feasible, duct-to-duct anastomosis can be performed safely in patients undergoing OLT for PSC.

Clinical features and treatment of sump syndrome following hepaticojejunostomy

BACKGROUND

Cholangitis after Roux-en-Y hepaticojejunostomy is usually caused by anastomotic stricture. A small number of cases present without evidence of obstruction and are ascribed to reflux of gastro-intestinal content into the biliary tree above the anastomosis (sump syndrome). Despite prophylactic rotating antibiotic therapy, the cholangitic episode may be severe and life-threatening.

METHODS

From 2001 to 2006, six patients who had undergone an end-to-side hepaticojejunostomy presented to our institution with recurrent episodes of biliary sepsis. Anastomotic stricture was excluded by liver MRI/MRCP and percutaneous transhepatic cholangiogram (PTC). Barium meal showed reflux of contrast into the biliary tree in all patients. Three patients had a short jejunal Roux limb (less than 50 cm) on pre-operative imaging.

RESULTS

Five patients underwent surgery and two of them had two operations. One patient had a Tsuchida antireflux valve and subsequently underwent lengthening of the Roux loop. Three patients had lengthening of the Roux loop; one underwent re-do hepaticojejunostomy and one had concomitant revision of the hepaticojejunostomy and lengthening of the Roux loop. The latter underwent further lengthening of the Roux loop. Three patients are cholangitis-free 6, 36 and 60 months after surgery; two still experience mild episodes of cholangitis.

CONCLUSIONS

An adequate length of the Roux loop is important to prevent reflux. However, Roux loop lengthening to 70 cm or more does not always resolve the problem and cholangitis, although generally less frequent and severe, may recur despite appropriate reconstructive or antireflux surgery. In these cases, life-long rotating antibiotics is the only available measure.

Biliary reconstruction for infantile living donor liver transplantation: Roux-en-Y hepaticojejunostomy or duct-to-duct choledochocholedochostomy?

Hepaticojejunostomy is a standard biliary reconstruction method for infantile living donor liver transplantation (LDLT), but choledochocholedochostomy for infants is not generally accepted yet. Ten pediatric recipients weighing no more than 10 kg underwent duct-to-duct choledochocholedochostomy (DD) for biliary reconstruction for LDLT. Patients were followed up for a median period of 26.8 months (range: 4.0-79.0 months). The incidence of posttransplant biliary complications for DD was compared with that for Roux-en-Y hepaticojejunostomy (RY). No DD patients and 1 RY patient (5%) developed biliary leakage (P > 0.05), and biliary stricture occurred in 1 DD patient (10%) and none of the RY patients (P > 0.05); none of the DD patients and 5 RY patients (25%) suffered from uncomplicated cholangitis after LDLT (P > 0.05), and 1 DD patient (10%) and 2 RY patients (10%) died of causes unrelated to biliary complications. In conclusion, both hepaticojejunostomy and choledochocholedochostomy resulted in satisfactory outcome in terms of biliary complications, including leakage and stricture, for recipients weighing no more than 10 kg.

Relevant histopathologic findings that distinguish acute cellular rejection from cholangitis in hepatic allograft biopsy specimens

BACKGROUND AND AIM

Histopathologic differential diagnosis of acute cellular rejection (ACR) and cholangitis continue to pose important problems following liver transplantation. The purpose of the present study was to evaluate the histopathologic features of ACR versus cholangitis.

METHODS

The following variables were evaluated among 36 hepatic allograft biopsy specimens, consisting of 21 with ACR (group 1) and 15 with cholangitis (group 2) for ductal neutrophilic infiltration, presence/density of portal eosinophilia, centrilobular necrosis, central/portal vein endothelialitis, pericentral inflammation, hepatocyte ballooning, hepatocanalicular/ductular cholestasis, hepatocyte apoptosis, lobular inflammation, ductular proliferation, periductal fibrosis/edema, ductular epithelial damage, and portal inflammation. Only the first biopsy samples of the ACR group were included in this study.

RESULTS

The incidences of ductal neutrophilic infiltration (93.3% vs 19%), hepatocanalicular cholestasis (86.7% vs 47.6%), ductular cholestasis (60% vs 0%), ductular proliferation (93.3% vs 4.8%), and periductal fibrosis/edema (93.3% vs 19%) were significantly greater in group 2 than group 1 (P < .05). In contrasts the incidences of portal eosinophilia (mean +/- SD, 3.37 +/- 3.9 vs 0.73 +/- 0.8), dense portal eosinophilia (mean +/- SD, 0.33 +/- 0.31 vs 0.11 +/- 0.16), central vein endothelialitis (0% vs 57.1%), portal vein endothelialitis (20% vs 95.2%), apoptosis (40% vs 71.4%), and necroinflammation (0% vs 90.5%) were significantly higher in group 1 (P < .05). The other parenchymal histopathologic changes and features of portal inflammation were similar in the 2 groups.

CONCLUSION

In the differential diagnosis, ductal changes (cholestasis, neutrophilic infiltration, proliferation, and periductal fibrosis/edema) favor cholangitis, whereas the presence and density of portal eosinophilia favor ACR. Portal inflammation is not a distinctive morphological finding.
