Abstract
BACKGROUND Benign biliary strictures can have a significant negative impact on patient quality of life. There are several modalities which can be utilized with the goal of stricture resolution. These techniques include balloon dilatation, placement of multiple plastic stents and more recently, the use of metal stents. The aim of this study was to evaluate the local success of self-expanding metal stents in successfully resolving benign biliary strictures. METHODS This was a single institution, retrospective case series. Patients included in our study were patients who underwent endoscopic retrograde cholangiopancreatography with placement of self expanding metal stents for benign biliary strictures at our institution between 2016-2022. Patients were excluded for the following: malignant stricture, and inability to successfully place metal stent. Data was evaluated using two-sided t-test with 95% confidence interval. RESULTS A total of 31 patients underwent placement of 43 self-expanding metal stents and met inclusion criteria. Mean age of patients was 59 ± 10 years, and were largely male (74.2% vs. 25.8%). Most strictures were anastomotic stricture post liver transplant (87.1%), while the remainder were secondary to chronic pancreatitis (12.9%). Complications of stent placement included cholangitis (18.6%), pancreatitis (2.3%), stent migration (20.9%), and inability to retrieve stent (4.7%). There was successful stricture resolution in 73.5% of patients with anastomotic stricture and 33.3% of patients with stricture secondary to pancreatitis. Resolution was more likely if stent duration was > / = 180 days (73.3% vs. 44.4%, p < 0.05). There was no demonstrated added benefit when stent duration was > / = 365 days (75% vs. 60.9%, p = 0.64). CONCLUSIONS This study demonstrates that self expanding metal stents are a safe and effective treatment for benign biliary strictures, with outcomes comparable to plastic stents with fewer interventions. This study indicates that the optimal duration to allow for stricture resolution is 180-365 days.

Abstract
Endoscopic methods are nowadays a priceless tool for the treatment of postoperative complications after hepatobiliary, pancreatic and thoracic surgery. Endoscopic decompression of the biliary tract is the treatment of choice for biliary duct leakage after cholecystectomy, hepatic resection or liver transplantation. Postoperative biliary duct stenosis can also be successfully treated by endoscopic balloon dilatation and implantation of various endoprostheses in most of the patients. In the case of pancreatic fistulas, especially those occurring after central or distal pancreatic resections, endoscopic decompression of the pancreatic duct can significantly contribute to rapid healing. Additionally, interventional endosonography provides a valuable treatment option for transgastric drainage of postoperative fluid collections, which often accompany a pancreatic fistula. Various treatment alternatives have been described for the bronchoscopic treatment of bronchopleural and tracheoesophageal fistulas, which often lead to the rapid alleviation of symptoms and often to the definitive closure of the fistula.

Endoscopic Management of Biliary Strictures after Orthotopic Liver Transplantation: A Single Center Experience Study. Diagnostics (Basel) 2022; 12:diagnostics12051221. [PMID: 35626376 PMCID: PMC9140460 DOI: 10.3390/diagnostics12051221] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2022] [Revised: 04/17/2022] [Accepted: 05/12/2022] [Indexed: 12/04/2022] Open
Abstract
Background and Aim. Endoscopic therapy is the method of choice in the management of biliary strictures after orthotopic liver transplantation (OLT). Even though the mainstay approach for OLT stricture complications is represented by consecutive procedures of multiple plastic stents (MPS) insertion, a valuable alternative is the use of fully covered self-expandable metal stents (FCSEMS). The aim of the study was to compare MPS with FCSEMS used in the management of OLT biliary strictures, in terms of clinical outcomes and complications. Material and Methods. This is a retrospective, single-center study conducted between February 2014 and November 2019 in the Clinical Emergency Hospital of Bucharest, Romania. We enrolled all consecutive patients who developed biliary strictures after OLT and were treated by endoscopic retrograde cholangiopancreatography (ERCP) either with MPS or FCSEMS. Results. Thirty-six patients were included in the study, 27 patients had MPS and nine patients had FCSEMS. 106 ERCP procedures were performed and 159 stents were inserted. The mean number of ERCP procedures required per patient was significantly higher for MPS than for FCSEMS (3.34 ± 1.46 vs. 2.11 ± 0.33, p < 0.001). In the FCSEMS group only one patient had three procedures, due to stent migration. Difficult cannulation was encountered in 22 patients, 18 patients from MPS group and four patients from FCSEMS group. Dilation was performed in 20 (77%) MPS patients and in four FCSEMS patients (44%). Overall, we used 159 stents for stricture resolution, 149 plastic stents and 10 FCSEMS. Mean number of stents inserted was significantly lower in the FCSEMS group compared to MPS group (1.16 ± 0.40 vs. 5.73 ± 2.64, p < 0.001). Conclusions. Stricture resolution using FCSEMS is comparable to MPS and even has some advantages. In line with prior studies, FCSEMS are effective, with fewer complications and similar outcome compared to plastic stents. Other particular aspects should be further assessed, especially long-term follow up of FCSEMS and their cost efficiency.

Local palliative therapies for unresectable malignant biliary obstruction: radiofrequency ablation combined with stent or biliary stent alone? An updated meta-analysis of nineteen trials. Surg Endosc 2022; 36:5559-5570. [PMID: 35296949 DOI: 10.1007/s00464-022-09181-2] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2021] [Accepted: 02/27/2022] [Indexed: 02/07/2023]
Abstract
BACKGROUND Recently, there has been a burgeoning interest in radiofrequency ablation combined with stent (RFA + Stent) for unresectable malignant biliary obstruction (MBO). This study aimed to perform a meta-analysis to evaluate the efficacy and safety of RFA + Stent compared with biliary stent alone. METHODS We searched PubMed, Cochrane Library, Embase, and Web of Science databases from their inception dates to June 20, 2021, for studies that compared RFA + Stent and stent alone for unresectable MBO. The main outcomes were survival, patency, and adverse effects. All meta-analyses were calculated using the random-effects model. RESULTS A total of 19 studies involving 1946 patients were included in this study. Compared with stent alone, RFA + Stent was significantly associated with better overall survival (HR 0.55; 95% CI 0.48, 0.63; P < 0.00001), longer mean survival time (SMD 2.20; 95% CI 1.17, 3.22; P < 0.0001), longer mean stent patency time (SMD 1.37; 95% CI 0.47, 2.26; P = 0.003), higher stent patency at 6 months (OR 2.82; 95% CI 1.54, 5.18; P = 0.0008). The two interventions had similar incidence of postoperative abdominal pain (OR 1.29; 95% CI 0.94, 1.78; P = 0.11), mild bleeding (OR 1.28; 95% CI 0.65, 2.54; P = 0.48), cholangitis (OR 1.09; 95% CI 0.76, 1.55; P = 0.65), pancreatitis (OR 1.39; 95% CI 0.82, 2.38; P = 0.22). Furthermore, the serum bilirubin levels and stricture diameter after operations were significantly alleviated than before operations, but the degree of alleviation between the two groups were not significantly different (all P > 0.05). CONCLUSION Although the alleviation of serum bilirubin and stricture diameter did not differ between the two interventions, RFA + Stent can significantly improve the survival and stent patency with comparable procedure-related adverse events than stent alone. Thus, RFA + Stent should be recommended as an attractive alternative to biliary stent alone for patients with unresectable MBO.

Abstract
Benign biliary strictures can be difficult to manage. Untreated biliary strictures can lead to complications, such as chronic cholestasis, jaundice, recurrent sepsis, and secondary biliary cirrhosis, which can have severe ramifications. The management landscape is constantly evolving, with the development of modifiable self-expandable metal stents and biodegradable stents. This review critically appraises current endoscopic treatment strategies, in particular focusing on the shortfalls, such as stent migration and stricture recurrence. It also proposes a treatment algorithm based on aetiologias and the location of the strictures.
