Percutaneous Transhepatic Biliary Drainage in the Management of Post-surgical Biliary Leaks

Application of percutaneous biliary drainage in the treatment of post-operative bile leakage after liver rupture: A case report

ABSTRACT

Post-operative bile leakage (POBL) is a serious complication following hepatobiliary surgery, with potentially life-threatening consequences if left untreated. This article presents a successful case of POBL management without surgical intervention. A 31-year-old male, diagnosed with bile leakage before hospitalisation, underwent percutaneous biliary drainage (PTBD) to address bilomas. Follow-up after 3 months indicated biloma atrophy and POBL healing but revealed bile duct stenosis. The patient received a larger biliary drainage tube, and after 1 month, the biloma and tube were removed. A 1-year follow-up confirmed the patient's excellent health. This case underscores the safety and efficacy of PTBD for managing POBL, offering a non-invasive alternative for patients with this complication. PTBD presents a viable treatment option for POBL cases, minimising the need for surgical interventions and their associated risks.

[Blunt abdominal trauma in children and adolescents: treatment concepts in the acute phase]

Fatal accidents due to blunt force trauma are the leading cause of death in children and adolescents [1]. Abdominal trauma is the third most common cause of death after traumatic brain injury and thoracic injuries [2]. Abdominal injury is seen in approximately 2-5% of children involved in accidents [3]. Blunt abdominal injuries are common sequelae of traffic accidents (for example as seat belt injury), falls, and sports accidents. Penetrating abdominal injuries are rare in central Europe. Spleen, liver, and kidney lacerations are the most common injuries after blunt abdominal trauma [4]. In most situations, nonoperative management (NOM) has become the gold standard with the surgeon leading the multidisciplinary treatment [5].

Percutaneous transhepatic cholangial drainage/percutaneous transhepatic biliary stent implantation for treatment of extrahepatic cholangiocarcinoma with obstructive jaundice

Extrahepatic cholangiocarcinoma is a malignant tumor originating from the extrahepatic bile duct including the hilar region to the lower bile duct of the common bile duct. With the development of interventional techniques and medical materials, percutaneous transhepatic cholangial drainage (PTCD) or percutaneous transhepatic biliary stent implantation (PTBS) has become the main treatment to relieve biliary obstruction. However, the occurrence of postoperative complications seriously affects the prognosis of patients, and the combination of biliary stenting with local treatment has been found to significantly prolong the time to biliary patency. This article reviews the progress of PTCD/PTBS in the treatment of extrahepatic cholangiocarcinoma with obstructive jaundice, evaluates its clinical efficacy, and points out the current problems and posible solutions to provide more reference for subsequent related studies.

Occurrence of spontaneous fistulas detected by contrast filling during computed tomography-guided percutaneous drainage placement of splenic and perisplenic fluid collections

BACKGROUND

Fistulas are serious complications of splenic and perisplenic fluid accumulations, which are often difficult to detect by routine imaging methods.

PURPOSE

To evaluate the occurrence of spontaneous fistulas detectable during computed tomography-guided percutaneous drainage placement (CTGDP) with contrast filling of splenic or perisplenic fluid collections and to assess characteristics in comparison with perihepatic or peripancreatic fluid accumulations, also being treated with CTGDP.

MATERIAL AND METHODS

In 127 CTGDP-procedures, pre-interventional CTs conducted with intravenous contrast agent were compared to post-interventional CTs including contrast filling of the drain to identify spontaneous fistulas. Patient and case characteristics were evaluated, and therapeutic consequences of fistula identification were analyzed.

RESULTS

A total of 43 perisplenic, 40 peripancreatic, and 44 perihepatic drains were evaluated; 13 (30.2%) perisplenic, 7 (17.5%) peripancreatic, and 10 (22.7%) perihepatic fistulas were observed. Concerning the frequency of fistulas, no significant difference was found between the patient groups (P = 0.39). All fistulas were solely proven in CT scans including contrast filling of the drain. Seven fistulas (23.3%) required additional interventions. Perihepatic drains were significantly more often associated with recent surgery (P < 0.001). The mean size of peripancreatic drains was significantly greater (11.8 ± 3.9 F; P < 0.001) than in perihepatic or perisplenic fluid collections.

CONCLUSION

Spontaneous fistulas detected during CTGDP of splenic or perisplenic fluid collections are common. Post-interventional contrast filling of the drain drastically improves the detection rate of perisplenic, peripancreatic and perihepatic fistulas simultaneously initiating appropriate follow-up interventions.

The role of interventional radiology in the management of refractory bile leaks

Refractory bile leaks represent a damaging sequela of hepatobiliary surgery and direct trauma. Management of bile leaks represents a challenging clinical problem. Despite advances in endoscopic techniques, interventional radiology continues to play a vital role in the diagnosis and management of refractory bile leaks. This article reviews strategies for optimizing the diagnosis and management of bile leaks and provides an overview of management strategies, including the management of complicated biliary leaks.

Biliopancreatic and biliary leak after pancreatoduodenectomy treated by percutaneous transhepatic biliary drainage

BACKGROUND

Complementary to percutaneous intra-abdominal drainage, percutaneous transhepatic biliary drainage (PTBD) might ameliorate healing of pancreatic fistula and biliary leakage after pancreatoduodenectomy by diversion of bile from the site of leakage. This study evaluated technical and clinical outcomes of PTBD for this indication.

METHODS

All patients undergoing PTBD for leakage after pancreatoduodenectomy were retrospectively evaluated in two tertiary pancreatic centers (2014-2019). Technical success was defined as external biliary drainage. Clinical success was defined as discharge with a resolved leak, without additional surgical interventions for anastomotic leakage other than percutaneous intra-abdominal drainage.

RESULTS

Following 822 pancreatoduodenectomies, 65 patients (8%) underwent PTBD. Indications were leakage of the pancreaticojejunostomy (n = 25; 38%), hepaticojejunostomy (n = 15; 23%) and of both (n = 25; 38%). PTBD was technically successful in 64 patients (98%) with drain revision in 40 patients (63%). Clinical success occurred in 60 patients (94%). Leakage resolved after median 33 days (IQR 21-60). PTBD related complications occurred in 23 patients (35%), including cholangitis (n = 14; 21%), hemobilia (n = 7; 11%) and PTBD related bleeding requiring re-intervention (n = 4; 6%). In hospital mortality was 3% (n = 2).

CONCLUSION

Although drain revisions and complications are common, PTBD is highly feasible and appears to be effective in the treatment of biliopancreatic leakage after pancreatoduodenectomy.

Percutaneous management of postoperative Bile leak after hepato-pancreato-biliary surgery: a multi-center experience

BACKGROUND

Bile leak (BL) after hepato-pancreato-biliary (HPB) surgery is associated with significant morbidity and mortality. Aim of this study was to evaluate effectiveness and safety of percutaneous transhepatic approach (PTA) to drainage BL after HPB surgery.

METHODS

Between 2006 and 2018, consecutive patients who were referred to interventional radiology units of three tertiary referral hospitals were retrospectively identified. Technical success and clinical success were analyzed and evaluated according to surgery type, BL-site and grade, catheter size and biochemical variables. Complications of PTA were reported.

RESULTS

One-hundred-eighty-five patients underwent PTA for BL. Technical success was 100%. Clinical success was 78% with a median (range) resolution time of 21 (5-221) days. Increased clinical success was associated with patients who underwent hepaticresection (86%,p = 0,168) or cholecystectomy (86%,p = 0,112) while low success rate was associated to liver-transplantation (56%,p < 0,001). BL-site,grade, catheter size and AST/ALT levels were not associated with clinical success. ALT/AST high levels were correlated to short time resolution (17 vs 25 days, p = 0,037 and 16 vs 25 day, p = 0,011, respectively) Complications of PTA were documented in 21 (11%) patients.

CONCLUSION

This study based on a large cohort of patients demonstrated that PTA is a valid and safe approach in BL treatment after HPB surgery.

Indian College of Radiology and Imaging Evidence-Based Guidelines for Percutaneous Image-Guided Biliary Procedures

Percutaneous biliary interventions are among the commonly performed nonvascular radiological interventions. Most common of these interventions is the percutaneous transhepatic biliary drainage for malignant biliary obstruction. Other biliary procedures performed include percutaneous cholecystostomy, biliary stenting, drainage for bile leaks, and various procedures like balloon dilatation, stenting, and large-bore catheter drainage for bilioenteric or post-transplant anastomotic strictures. Although these procedures are being performed for ages, no standard guidelines have been formulated. This article attempts at preparing guidelines for performing various percutaneous image-guided biliary procedures along with discussion on the published evidence in this field.

Imaging findings and available percutaneous techniques for the treatment of bile leaks after hepatobiliary surgery

Background

The aim of this study was to evaluate the diagnosis and management of postoperative bile leaks, reporting typical diagnostic findings and available percutaneous techniques in association with other diagnostic and management methods.

Methods

Thirty-six patients (28 male) were treated for postoperative bile leaks. A biliary leak was clinically suspected in case of persistent leakage of bilious material from a surgical drain, or in the presence of non-specific symptoms such as abdominal pain, fever and anorexia, with or without laboratory alteration of liver enzymes. Radiological confirmation was mainly based on noninvasive methods such as ultrasound, computed tomography, and magnetic resonance cholangiopancreatography. We assessed each treatment by evaluating multiple factors, including technical success (TS) and clinical effectiveness (CE), defined as primary or secondary. We also evaluated overall CE (OCE), defined as leak control with either single or multiple procedures.

Results

TS and OCE were achieved in all patients (36/36; 100%) with a grade A or B biliary leak. No grade C was observed. There were no major complications. Minor complications were observed in 7/36 (19.4%) patients. No procedure-related deaths occurred.

Conclusions

In our study, considering all percutaneous techniques, leak healing was achieved in all the patients with a grade A or B biliary leak. These procedures provide a less invasive approach and are increasingly recognized as having a significant role in the management of complications and should be considered as an integral component in the postoperative management of these patients.

Clinical efficacy of laparoscopic modified loop cholecystojejunostomy for the treatment of malignant obstructive jaundice

OBJECTIVE

This study was performed to summarize our experience and investigate the safety and efficacy of laparoscopic modified loop cholecystojejunostomy for the treatment of malignant obstructive jaundice.

METHODS

Thirteen patients with malignant obstructive jaundice who underwent laparoscopic modified loop cholecystojejunostomy from March 2015 to March 2016 were retrospectively reviewed. The patients' characteristics, operation time, postoperative intestinal recovery time, length of hospital stay, postoperative bilirubin level, and complications were analyzed.

RESULTS

The patients were followed up as outpatients for 2 years. Nine patients with pancreatic head carcinoma, one patient with periampullary carcinoma, and three patients with distal bile duct carcinoma successfully underwent laparoscopic modified loop cholecystojejunostomy. The mean operation time was 176 ± 45 minutes, and the mean length of hospital stay was 9.5 ± 2.8 days. The serum total bilirubin concentration and gamma-glutamyl transferase concentration significantly decreased on postoperative day 7. The median follow-up time was 7 months. No patients developed bile leakage or required a reoperation.

CONCLUSIONS

Laparoscopic modified loop cholecystojejunostomy is not only safe and minimally invasive, but it is also feasible for patients with malignant obstructive jaundice.

Biliary injuries after pancreatic surgery: interventional radiology management

Bile duct injuries are among the most feared complications after pancreatic surgery. Most of these surgical complications are related to iatrogenic injuries and include bile leakage, biliary duct obstruction or stricture and infection. A wide range of Interventional Radiology treatment options are currently available. The options include percutaneous transhepatic cholangiography (PTC), percutaneous transhepatic biliary drainage (PTBD), percutaneous balloon dilatation and stenting, image-guided percutaneous abscess drainage. The purpose of this review is to describe the current evidence in this continuously evolving field.

Causes and Rates of 30-day Readmissions after Percutaneous Transhepatic Biliary Drainage Procedure

Purpose To investigate rates and causes of 30-day readmission for patients who undergo percutaneous transhepatic biliary drainage (PTBD) procedures. Materials and Methods In this retrospective study, PTBD procedures performed at a tertiary care institution (June 2008 to May 2013) were reviewed. For each patient, the first 30-day readmission was used to determine cause of readmission. Two interventional radiologists independently categorized causes for readmission as planned or unplanned, and unplanned causes as related to or unrelated to interventional radiology. Interventional radiology-related readmissions were categorized as potentially preventable or unpreventable. Factors associated with higher odds for 30-day readmission were identified with univariable and multivariable analysis. Results There were 266 procedures in 266 patients (mean age, 67 years; interquartile range, 57-76 years; 53.4% men). The cause of obstruction was malignant in 50.0% of patients (133 of 266). There were 122 of 266 patients (45.9%) readmitted within 30 days. Of these readmissions, 44 of 122 (36.1%) were planned and 78 of 122 (63.9%) were unplanned. A majority of unplanned readmissions (57 of 78; 73%) were related to interventional radiology. Of unplanned interventional radiology-related readmissions, 16% (nine of 57) were related to periprocedural complications and 51% (29 of 57) were considered preventable. At multivariable analysis, Medicaid insurance (odds ratio, 3.68; 95% confidence interval: 1.52, 9.99; P = .009) and bilateral PTBDs (odds ratio, 5.81; 95% confidence interval: 1.79, 18.90; P = .003) were associated with 30-day readmission. Conclusion Thirty-day readmissions after primary biliary drainage are common and a majority of unplanned readmissions are drain-related. Nearly half of unplanned interventional radiology-related readmissions are potentially preventable. © RSNA, 2018 See also the editorial by Nikolic in this issue.

Combined surgical and interventional radiological treatment for biliary leakage following iatrogenic biliary obstruction

Biliary leakage is a challenging complication when managing the bile duct strictures. The etiology of benign strictures of the biliary tree may have different etiologies but iatrogenic is the most common, with relevant increase after introduction of laparoscopic procedures.

Interventional radiologist plays a key role, both in diagnosis and treatment of biliary strictures and leakage.

We report on a case of a 39-year-old woman affected by abdominal pain and jaundice after laparoscopic cholecystectomy; jaundice was caused by surgical clipping of the common bile duct. The combined management by surgeon and interventional radiologist, consisting of removal of surgical clip and percutaneous management of biliary leakage, successfully resolved the leakage with clinical success.
