Abstract
BACKGROUND AND AIM Double-balloon endoscopic retrograde cholangiography (DBERC) is a valuable procedure for patients with altered gastrointestinal anatomy. Nonetheless, it is time-consuming and burdensome for both patients and endoscopists, partly because route selection in the reconstructed bowel with complicating loop is challenging. Carbon dioxide insufflation enterography is reportedly useful for route selection in the blind loop. This prospective randomized clinical trial investigated the usefulness of carbon dioxide insufflation enterography for route selection by comparing it with conventional observation. METHODS Patients scheduled to undergo DBERC were consecutively registered. They were divided into carbon dioxide insufflation enterography and conventional groups via randomization according to stratification factors, type of reconstruction methods, and experience with DBERC. The primary endpoint was the correct rate of initial route selection. The secondary endpoints were the insertion time, examination time, amount of anesthesia drugs, and complications. RESULTS The correct rate of route selection was significantly higher in the carbon dioxide insufflation enterography group (23/25, 92%) than in the visual method (15/25, 60%) (P = 0.018). The insertion time was significantly shorter in the carbon dioxide insufflation enterography group than in the visual group (10.8 ± 11.1 min vs 29.8 ± 15.7 min; P < 0.001). No significant differences in complications were noted between the two groups. The amounts of sedatives and analgesics used were significantly lower in the carbon dioxide insufflation enterography group (P < 0.001 and P < 0.001, respectively). CONCLUSIONS Carbon dioxide insufflation enterography can reduce the burden of DBERC on patients and endoscopists by shortening the examination time and reducing the amount of medication.

The Evaluation of Clinical Status of Endoscopic Retrograde Cholangiography for the Placement of Metal and Plastic Stents in Cholangiocarcinoma Therapy. COMPUTATIONAL AND MATHEMATICAL METHODS IN MEDICINE 2022; 2022:5741437. [PMID: 36267306 PMCID: PMC9578868 DOI: 10.1155/2022/5741437] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/20/2022] [Revised: 09/07/2022] [Accepted: 09/20/2022] [Indexed: 11/27/2022]
Abstract
Objective Cholangiocarcinoma is a common malignant tumor that occurs in the bile duct system, which can be treated by using the endoscopic retrograde cholangiography (ERCP). This study was aimed at exploring the therapeutic effect of ERCP with metal stent and plastic stent for cholangiocarcinoma. Methods The clinical data of 71 patients with cholangiocarcinoma treated by ERCP in our hospital from June 2020 to October 2021 were retrospectively analyzed. According to different stent types, the patients were divided into plastic stent group (n = 43) and metal stent group (n = 28). Patients in the plastic stent group and metal stent group were received with plastic stent and metal stent, respectively. The indexes of liver function (serum alkaline phosphatase (ALT), direct bilirubin (DBIL), glutamic oxaloacetic transaminase (AST), alkaline phosphatase (ALP), and total bilirubin (TBIL)), postoperative complications, success rate of stent implantation, and survival time of patients in the two groups were determined. Logistic multivariate regression analysis was used to analyze the prognostic factors of postoperative cholangiocarcinoma. Results The liver function indexes of the two groups were significantly improved after treatment with the stent, in which the ameliorative effect in the metal stent group was better than that in the plastic stent group (P < 0.05). The incidence of postoperative complications in the plastic stent group and the metal stent group was 53.49% and 14.29%, respectively, and the success rate of stent placement was 60.47% and 96.43%, respectively. The incidence of complications in the metal stent group was lower than that in the plastic stent group, and the success rate of stent placement was higher than that in the plastic stent group (P < 0.05). The median survival time of patients in the plastic stent group and the metal stent group was 8.15 and 11.83 months, respectively. The survival time of patients in the metal stent group was longer than that of the plastic stent group. The median survival time of patients with types I, II, III, and IV was 12.73, 11.54, 10.57, and 9.36 months, respectively. The survival time of patients with stage I was significantly higher than that of patients with types II, III, and IV. There was an inverse relationship between the disease type and the survival time of patients. Logistic multivariate regression analysis showed that tumor diameter ≥ 5 cm, portal vein invasion, lymph node metastasis, and classification of hilar cholangiocarcinoma were the risk factors (P < 0.05) and metal stent type was the protective factor (P < 0.05). Conclusion In the clinical treatment of patients with cholangiocarcinoma, the placement of metal stent and plastic stent under ERCP plays an important role. The placement of the metal stent under ERCP has a higher success rate and better prognosis and can prolong the survival time of patients to a greater extent, but the price of the metal stent is relatively expensive. For patients with an expected survival period of more than 4-6 months, the metal stent should be considered; otherwise, the plastic stent can be used to maintain cost-effectiveness. Therefore, it is necessary to comprehensively analyze the patient's economic affordability, expected survival time, stent drainage time, and personal needs and then select an appropriate treatment method.

Abstract
OBJECTIVE Migration of a fish bone to the bile duct or pancreatic duct is a possible complication after pancreaticoduodenectomy (PD). The aim of this study was to clarify the incidence and indications for intervention in such cases. METHODS We reviewed the cases with fish bone migration after PD detected on computed tomography (CT) scan between October 2000 and October 2020 were reviewed and the incidence of fish bone migration, presence of symptoms and signs, therapeutic modalities and patient outcomes were analyzed. RESULTS Among the 1475 PD procedures performed at our institution during the study period, 14 cases of fish bone migration were noted on CT, the incidence of which was 0.95% (14/1475). The time duration from surgery to the detection of fish bone ranged from 88 to 5902 days (median 917 d). Ten patients remained asymptomatic without therapeutic intervention for up to 2919 days (median 509 d). Four patients were treated by endoscopy, either at the patient's request (n = 1) or because of their symptoms (n = 3), and removal was successful in three cases but failed in one case in which the fish bone migrated to the right intrahepatic bile duct. No surgical treatment was required in any case. CONCLUSIONS The incidence of fish bone migration on CT after PD was about 1%. Some cases resolved spontaneously, and most of the asymptomatic cases required no intervention. For symptomatic cases, endoscopic treatment should be considered first. It is important to confirm the location of the fish bone by CT and determine whether it can be removed.

Abstract
Bile duct and anastomotic strictures and intrahepatic stones are common postoperative complications of congenital biliary dilatation (CBD). We performed double-balloon endoscopic retrograde cholangiography (DBERC) for diagnostic and therapeutic purposes after radical surgery. We focused on the effectiveness of DBERC for the treatment of postoperative complications of CBD patients. Bile duct and anastomotic strictures and intrahepatic stones are common postoperative complications of congenital biliary dilatation (CBD). We performed double-balloon endoscopic retrograde cholangiography (DBERC) for diagnostic and therapeutic purposes after radical surgery. We focused on the effectiveness of DBERC for the treatment of postoperative complications of CBD patients. This retrospective study included 28 patients who underwent DBERC (44 procedures) after radical surgery for CBD between January 2011 and December 2019. Strictures were diagnosed as “bile duct strictures” if endoscopy confirmed the presence of bile duct mucosa between the stenotic and anastomotic regions, and as “anastomotic strictures” if the mucosa was absent. The median patient age was 4 (range 0–67) years at the time of primary surgery for CBD and 27.5 (range 8–76) years at the time of DBERC. All anastomotic strictures could be treated with only by 1–2 courses of balloon dilatation of DBERC, while many bile duct strictures (41.2%) needed ≥ 3 treatments, especially those who underwent operative bile duct plasty as the first treatment (83.3%). Although the study was limited by the short follow-up period after DBERC treatment, DBERC is recommended as the first-line treatment for hepatolithiasis associated with biliary and anastomotic strictures in CBD patients, and it can be safely performed multiple times.

Abstract
A comprehensive understanding of gastrointestinal anatomy is essential for performance of any endoscopic procedure. Surgical approaches to therapy have become increasingly common in the past decade, which has resulted in a substantial proportion of patients with surgically altered anatomy who require endoscopy. In parallel with the obesity epidemic, bariatric surgery for obesity management has been widely adopted. In response to these trends, gastroenterologists must become familiar with patient anatomy after these surgical interventions and understand the implications of this altered anatomy on the current array of available endoscopic modalities for diagnosis and therapy. This review describes the range of surgically altered anatomy commonly encountered in the upper gastrointestinal tract. For each foregut location-esophagus, stomach, and small bowel-we describe indications for and specific details of the range of common surgical approaches affecting this regional anatomy. We then provide an endoscopic roadmap through the altered anatomy resulting from these surgical interventions. Finally, we address the impact of postsurgical anatomy on performance of endoscopic ultrasound and endoscopic retrograde cholangiopancreatography, with guidance surrounding how to successfully execute these procedures. Evolution of endoscopic approaches over time might be expected to enhance the safety and efficacy of these interventions in patients with surgically altered anatomy.

Abstract
PURPOSE To investigate late complications after surgery for congenital biliary dilatation (CBD). METHODS We retrospectively reviewed the patients treated for late postoperative complications of extrahepatic bile duct resection with bilioenteric anastomosis for CBD at our hospital between 1999 and 2019. RESULTS Twenty-seven complications, including bile duct stenosis with (n = 19) or without (n = 3) hepatolithiasis, remnant intrapancreatic bile duct (n = 2), intestinal obstruction (n = 2), and refractory cholangitis (n = 1) were treated in 26 patients. The median age at radical surgery and the initial treatment of complications was 3 years, 2 months and 14 years, 5 months, respectively. The median period from radical surgery to initial treatment of complications was 7 years, 1 month. Before 2013, bile duct stenosis was initially treated with bile duct plasty (n = 11) or hepatectomy (n = 3), and 71.4% (n = 10) of patients needed further treatment; after 2013, double-balloon endoscopic retrograde cholangiography (DBERC) was used (n = 8), and 25% (n = 2) of patients needed further treatment. Patients with remnant intrapancreatic bile duct, intestinal obstruction, and refractory cholangitis required surgery. CONCLUSION Long-term follow-up is necessary after surgery for congenital biliary dilatation. DBERC is thus considered to be useful for bile duct stenosis management.

Abstract
BACKGROUND Retrograde cholangiopancreatography using double-balloon endoscopic retrograde cholangiography (DBERC) is a valuable technique to treat biliary stone and jejunobiliary anastomotic stenosis in patients with altered gastrointestinal anatomy. The accurate selection of the route at the anastomosis branch is one of the most important factors in reaching the target in a timely manner.
AIM To determine the accuracy of carbon dioxide insufflation enterography (CDE) at the branch for selecting the correct route during DBERC.
METHODS We enrolled 52 consecutive patients scheduled for DBERC at our institution from June 2015 to November 2017. Route selection via two methods (visual observation and CDE) was performed in each patient. We determined the correct rate of route selection using CDE.
RESULTS Thirty-three patients had a jejunojejunal anastomosis and 19 patients had a gastrojejunal anastomosis. The therapeutic target region was reached in 50 patients. The mean procedure times from the teeth to the target (total insertion time), from the teeth to the branch, and from the branch to the target, and the mean total examination time were 15.2, 5.0, 8.2, and 60.3 min, respectively. The rate of correct route selection using visual observation and CDE were 36/52 (69.2%) and 48/52 (92.3%), respectively (P = 0.002). The rate of correct route selection using CDE in patients with a jejunojejunal anastomosis was 29/33 (87.8%), and the rate in patients with a gastrojejunal anastomosis was 19/19 (100%).
CONCLUSION CDE is helpful in selecting the route at the branch in the anastomosis for more timely access to the target in patients with altered gastrointestinal anatomy undergoing DBERC.

Liver resections in patients with prior bilioenteric anastomosis are predisposed to develop organ/space surgical site infections and biliary leakage: results from a propensity score matching analysis. Surg Today 2020; 51:526-536. [PMID: 32785844 DOI: 10.1007/s00595-020-02105-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2020] [Accepted: 07/28/2020] [Indexed: 02/07/2023]
Abstract
PURPOSE The aims of this study were to compare the perioperative outcomes after hepatectomy with prior bilioenteric anastomosis to those without prior anastomosis, and to elucidate the mechanisms and preventative measures of its characteristic complications. METHODS The demographic data and perioperative outcomes of 525 hepatectomies performed between January 2007 and December 2018, including 40 hepatectomies with prior bilioenteric anastomosis, were retrospectively analyzed. RESULTS A propensity score matching analysis demonstrated that hepatectomies with prior bilioenteric anastomosis were associated with a higher frequency of major complications (p = 0.015), surgical site infection (p = 0.005), organ/space surgical site infection (p = 0.003), and bile leakage (p = 0.007) compared to those without. A multivariate analysis also elucidated that prior bilioenteric anastomosis was one of the independent risk factors of organ/space surgical site infection. In the patients with prior bilioenteric anastomosis, bile leakage was associated with organ/space surgical site infection at a significantly higher rate than those without prior bilioenteric anastomosis (p < 0.001). CONCLUSIONS Prior bilioenteric anastomosis is a strong risk factor for organ/space surgical site infections, which might be induced by bile leakage. To prevent infectious complications after hepatectomy with prior bilioenteric anastomosis, meticulous liver transection to reduce bile leakage rate is thus considered to be mandatory.
