Abstract
BACKGROUND The incidence of post-endoscopic retrograde cholangiopancreatography (ERCP) cholangitis (PEC) in patients who underwent mechanical lithotripsy (ML) for large stone removal is high (up to 13.3%). One of the main causes is remaining small fragments or sludge that can impair normal biliary drainage. Endoscopic placement of a nasobiliary tube or a conventional plastic biliary stent has been commonly used under such conditions, but the patient may suffer from significant discomfort after the placement of a nasobiliary tube, while additional endoscopy is required for stent removal. We developed a biliary spontaneous dislodgement spiral stent (BSDSS) to overcome those shortcomings. AIM To evaluate the feasibility, safety, and effectiveness of inserting a BSDSS for patients who underwent ML for large stone removal. METHODS We conducted a single-center, retrospective, cohort study at West China Hospital, Sichuan University. A total of 91 consecutive patients with large biliary stones (≥ 10 mm) in the common bile duct who underwent ML between November 2017 and July 2018 were included. The 49 eligible patients were divided into the BSDSS group and the nasobiliary tube group. Technical success, post-ERCP adverse events (including PEC, post-ERCP pancreatitis, stone recurrence, BSDSS retention, self-extraction and dislocation of the nasobiliary tube), drainage time, and postoperative stay were measured and compared. RESULTS Twenty-one patients in the BSDSS group and 28 patients in the nasobiliary tube group were included in the analyses. The baseline characteristics and clinical information were similar in the two groups. Insertions of BSDSS and nasobiliary tube were technically successful in all 49 patients. There was no significant difference in the incidence of overall post-ERCP adverse events between the two groups (4.8% in the BSDSS group vs 17.9% in the nasobiliary tube group, P = 0.219). The median duration of drainage time (3 d in the BSDSS group vs 4 d in the nasobiliary tube group) and length of postoperative stay (4 d in the BSDSS group vs 5 d in the nasobiliary tube group) also did not differ (P = 0.934, and P = 0.223, respectively). CONCLUSION Endoscopic placement of a BSDSS appears to be feasible, safe and effective for patients who underwent ML for large stone removal.

Abstract
OBJECTIVE To assess the feasibility, safety, and efficacy of Y-shaped jogged stent in patients with malignant hilar biliary obstruction. METHODS A total of 196 patients with malignant hilar biliary obstruction treated by biliary tract stent implantation from August 2010 to August 2017 were retrospectively reviewed. Seventeen consecutive patients who were treated with Y-shaped jogged stent implantation were identified as the Y-shaped jogged stent implantation group. Seventeen matched patients undergoing unilateral stent placement combined with percutaneous transhepatic cholangial drainage (PTCD) were enrolled as the control group. Baseline characteristics of patients, stent patency time, and survival time were compared. RESULTS There was no significant difference in the age, gender, tumor type and stage, biliary obstruction classification, bilirubin level at diagnosis, presence of metastasis, or chemotherapy between the Y-stent group and the control group (P > 0.05). One week after surgery, the reduction rate of bilirubin was significantly higher in the Y-stent group (88.2% vs 53.0%, P < 0.05). The mean stent patency time was longer in the Y-stent group (7.3 ± 1.0 months vs 5.7 ± 0.9 months, P < 0.05). The mean survival time of the Y-stent group (9.1 ± 1.5 months) was longer than the control group (7.2 ± 1.1 months, P > 0.05). There was no severe complication occurred in both two groups. CONCLUSION Y-shaped jogged stent implantation was a safe, feasible, and effective approach in the treatment of patients with malignant hilar biliary obstruction, with the significantly prolonged stent patency time and survival time.

Abstract
To compare patency between suspended over length biliary stents (SOBSs; made from nasobiliary tube) and conventional plastic biliary stents (CPBSs).We retrospectively analyzed 61 patients with extrahepatic biliary stricture who underwent SOBS placement (intrahepatic bile duct) and 74 patients who underwent CPBS placement. Stent patency and complications were compared.The SOBS group was slightly older and contained more females than the CPBS group but other baseline characteristics were similar. Malignant biliary obstruction accounted for 57.4% (SOBS group) and 45.9% (CPBS group) of cases. Technical success rate, hospital stay and post-procedure complications were similar between groups. Median patency in the CPBS and SOBS group was 116 (2-360) days and 175 (3-480) days, respectively (P <.001). The SOBS group had lower stent occlusion rates than the CPBS group at 3 months (9.8% vs 36.5%), 4 months (22.0% vs 55.4%), 5 months (35.6% vs 67.6%), and 6 months (39.3% vs 77.0%) (all P <.01). In Cox regression analysis, stent type (SOBS vs CPBS) was the only factor associated with patency (hazard ratio [HR]: 3.449; 95% CI: 1.973-6.028; P <.001).SOBS may have better medium-term patency than CPBS for benign/malignant biliary stricture.

Abstract
Background/Aims The role of endoscopic preoperative biliary drainage (PBD) for pancreatic head cancer is controversial because of the high incidence of stent occlusion before surgery. This study was performed to evaluate the feasibility and safety of PBD using a fully covered self-expandable metallic stent (FCSEMS). Patients and Methods This multicenter prospective study involved 26 patients treated for pancreatic head cancer with distal bile duct obstruction from April 2011 to March 2013. An FCSEMS was endoscopically placed in 24 patients. Among these, 7 patients were diagnosed with unresectable cancer, and 17 underwent surgery at a median of 18 days after FCSEMS placement. The main outcome measure was preoperative and postoperative adverse events. Results Two adverse events (cholecystitis and insufficient resolution of jaundice) occurred between FCSEMS placement and surgery (12%). Postoperative adverse events occurred in eight patients (47%). The cumulative incidence of stent-related adverse events 4 and 8 weeks after FCSEMS placement among the 24 patients who underwent this procedure were 19%. Conclusions PBD using an FCSEMS is feasible in patients with resectable pancreatic head cancer. Placement of an FCSEMS can be an alternative PBD technique when surgery without delay is impossible. A larger randomized controlled trial is warranted.

Abstract
Immunoglobulin (Ig)G4-associated cholangitis (IAC) is one of the common organ manifestations of IgG4-related systemic disease (ISD). IAC and autoimmune pancreatitis (AIP) may mimic sclerosing cholangitis, cholangiocarcinoma, or pancreatic carcinoma. Diagnosis is based on a combination of clinical, biochemical, radiological, and histological findings.To study the clinical presentation of and treatment strategy for IAC, we reviewed clinical, serologic, and imaging characteristics, as well as treatment response, in 39 patients with IAC. The majority of patients were men (82%). Clinical features on presentation included obstructive jaundice in 26 patients (67%) and abdominal pain in 20 (51%). Positive IgG4 immunostaining was seen in 27 patients. The median serum IgG4 level before treatment was 769.4 mg/dL (range, 309.1-1229.7 mg/dL). After the steroid therapy, the median serum IgG4 level in 23 patients was 247.0 mg/dL (range, 139.0-355.0 mg/dL). Cholangiograms were available in 36 (92%) patients. Stenosis of the lower part of the common bile duct was found in 26 of 39 patients. Stenosis was diffusely distributed in the intra- and extrahepatic bile ducts in 14 of 39 patients. Additionally, strictures of the bile duct were detected in the hilar hepatic lesions in 27 of 39 patients. AIP was the most frequent comorbidity (35/39 in this study) of IAC. Other affected organs included eyes (n = 6), salivary glands (sialadenitis, n = 10), lymph nodes (mediastinal and axillary, n = 3), kidneys (n = 2), and the retroperitoneum (retroperitoneal fibrosis, n = 2).Regarding treatment, 29 patients were treated with steroids, of whom one underwent pancreatoduodenectomy, and one underwent choledochojejunostomy. Eight patients were treated with biliary stents. The remaining 19 patients took prednisolone alone. Eight patients achieved spontaneous resolution. Four patients with suspected pancreatic cancer or cholangiocarcinoma underwent surgery, including 2 patients who also received postoperative steroids. All patients were regularly followed up for 9 to 36 months. Only 2 patients in the steroids treatment group relapsed to manifest obstructive jaundice and high serum IgG4 levels. These 2 patients were treated with steroids and biliary stents, resulting in complete remission.We also review the diagnostic and therapeutic management and discuss recent pathophysiological findings, which might aid in understanding the molecular mechanisms contributing to IAC and other manifestations of IgG4-related diseases (IgG4-RD). Biomarkers that are more accurate are needed to correctly diagnose IAC and prevent misdiagnoses and unnecessary therapeutic interventions.

Abstract
This study aimed to assess the clinical value of transprepancreatic septotomy indwelling guide wire or pancreatic duct stent in intractable endoscopic retrograde cholangiopancreatography (ERCP) for bile duct cannulation.Of the 2107 patients treated by ERCP, a total of 81 cases with difficult bile duct cannulation underwent transprebiliopancreatic septotomy (referred to as the septotomy group, 37 cases) and transprepancreatic septotomy with pancreatic duct stent (modified septotomy group, 44 cases). Success rates of cannulation and postoperative complications for both methods were compared.Among them, 77 cases were successfully administered bile duct cannulation. The success rates of the septotomy and modified septotomy groups were 91.89% and 97.73%, respectively, with no significant difference (P = .489). Of the 77 patients, 12 cases had complications. The septotomy group included 7 acute pancreatitis, 1 bleeding, and 1 biliary tract infection cases; while in the modified septotomy group, there were 1 acute pancreatitis, 1 bleeding, and 1 biliary tract infection cases. The occurrence rate of acute pancreatitis in the modified septotomy group was lower than that of the septotomy group (2.33% vs 20.59%) with a significant difference (P = .026).These findings indicate that transprepancreatic septotomy with pancreatic duct stent seems to be a safe and feasible operation with reducing complication rates.

Abstract
BACKGROUND Laparoscopic cholangiojejunostomy (LCJ) with hand-sewn technique is technically difficult and requires a long time to master. The purpose of this study was to assess the feasibility of LCJ using a novel magnetic compression device (MCD) in dogs. METHODS The concept of the purse-string technique of the circular stapler was used to design a novel MCD for LCJ. To test the feasibility of this MCD in a more clinically relevant situation, four dogs were subjected to bile duct ligation. When the diameter of their bile ducts reached 10 mm, LCJ using MCD was performed. The anastomotic time and expelling time of the magnets were assessed. RESULTS In the clinically relevant model of bile duct obstruction in dogs, LCJ created with this MCD yielded patent anastomoses. The LCJ procedure using this novel MCD was simple, and the mean anastomotic time was 12.9 ± 1.73 min. All animals recovered smoothly after the operation without complications. All magnets spontaneously passed through the rectum in 14.5 ± 2.08 d after LCJ. CONCLUSIONS LCJ in dogs using this novel MCD is feasible.

Abstract
Recently, the novel SpyGlass DS Direct Visualization system (SPY DS) has become available. This system offers several advantages over the conventional SPYGlass system. This study evaluated the clinical feasibility and efficacy of diagnostic and therapeutic procedures for biliary disorder using SPY DS.In this retrospective study, consecutive patients who had biliary disorder were enrolled between November 2015 and February 2016. All patients could not be diagnosed or treated by standard endoscopic retrograde cholangiopancreatography in our hospital or at another hospital.A total of 28 consecutive patients (21 men and 7 women; median age, 73 years; age range, 55-87 years) were retrospectively enrolled in this study. Among them, diagnostic procedure was performed in 20 patients, and 8 patients underwent therapeutic procedures. The technical success rate for diagnostic procedures was 100% (20/20). Diagnostic accuracy was 100% (19/19). The technical success rate for therapeutic procedures was 88% (7/8). Among these 8 patients, 4 patients with common bile duct stones underwent electrohydraulic lithotripsy. One patient successfully underwent guidewire insertion to remove a migrated plastic stent. The 3 remaining patients underwent SPY DS to insert a guidewire for left bile duct obstruction and for posterior bile duct branch. In the patient who underwent guidewire insertion for left hepatic bile duct obstruction cause by primary sclerosing cholangitis, we could not advance the guidewire into the left hepatic bile duct. No adverse events were seen. Median SPY DS insertion time was 21 min (range, 8-32 min).Single-operator cholangioscopy using SPY DS was feasible and had a marked clinical impact in patients with biliary disease. Additional case reports and prospective studies are needed to examine further applications of this system.

Abstract
AIM: To investigate the safety and feasibility of needlescopic grasper-assisted single-incision laparoscopic common bile duct exploration (nSIL-CBDE) by comparing the surgical outcomes of this technique with those of conventional laparoscopic CBDE (CL-CBDE).
METHODS: We retrospectively analyzed the clinical data of patients who underwent CL-CBDE or nSIL-CBDE for the treatment of common bile duct (CBD) stones between January 2000 and December 2014. For performing nSIL-CBDE, a needlescopic grasper was also inserted through a direct puncture below the right subcostal line after introducing a single-port through the umbilicus. The needlescopic grasper helped obtain the critical view of safety by retracting the gallbladder laterally and by preventing crossing or conflict between laparoscopic instruments. The gallbladder was then partially dissected from the liver bed and used for retraction. CBD stones were usually extracted through a longitudinal supraduodenal choledochotomy, mostly using flushing a copious amount of normal saline through a ureteral catheter. Afterward, for the certification of CBD clearance, CBDE was performed mostly using a flexible choledochoscope. The choledochotomy site was primarily closed without using a T-tube, and simultaneous cholecystectomies were performed.
RESULTS: During the study period, 40 patients underwent laparoscopic CBDE. Of these patients, 20 underwent CL-CBDE and 20 underwent nSIL-CBDE. The operative time for nSIL-CBDE was significantly longer than that for CL-CBDE (238 ± 76 min vs 192 ± 39 min, P = 0.007). The stone clearance rate was 100% (40/40) in both groups. Postoperatively, the nSIL-CBDE group required less intravenous analgesic (pethidine) (46.5 ± 63.5 mg/kg vs 92.5 ± 120.1 mg/kg, P = 0.010) and had a shorter hospital stay than the CL-CBDE group (3.8 ± 2.0 d vs 5.1 ± 1.7 d, P = 0.010). There was no significant difference in the incidence of postoperative complications between the two groups.
CONCLUSION: The results of this study suggest that nSIL-CBDE could be safe and feasible while improving cosmetic outcomes when performed by surgeons trained in conventional laparoscopic techniques.

Abstract
Decompression of the biliary system in patients with malignant biliary obstruction has been widely accepted and implemented as part of the care. Despite a wealth of literature, there remains a significant amount of uncertainty as to which approach would be most appropriate in different clinical settings. This review covers stenting of the biliary system in cases of resectable or palliative malignant biliary obstruction, potential candidates for biliary drainage, technical aspects of the procedure, as well as management of biliary stent dysfunction. Furthermore, periprocedural considerations including proper mapping of the location of obstruction and the use of antibiotics are addressed.

Abstract
Roux-en-Y hepaticojejunostomy anastomosis is the treatment of choice for common hepatic duct injury type E2. It has been performed laparoscopically with the advancement of laparoscopic skill. Recently, a telemanipulative robotic surgical system was introduced, providing laparoscopic instruments with wrist-arm technology and 3-dimensional visualization of the operative field. We present a case of 36-year-old female patient who had undergone elective cholecystectomy 2 mo ago for gall stones and had a common bile duct injury during surgery. As the stricture was old and complete it could not be tackled endoscopically. We did a laparoscopic assisted adhesiolysis followed by robotic Roux-en-Y hepaticojejunostomy. No intraoperative complications or technical problems were encountered. Postoperative period was uneventful and she was discharged on the 4th postoperative day. At follow-up, she is doing well without evidence of jaundice or cholangitis. This is the first reported case of robotic hepaticojejunostomy following common bile duct injury. The hybrid technique gives the patient benefit of laparoscopic adhesiolysis and robotic suturing.

Abstract
BACKGROUND Treatment or prevention of a benign biliary tree stricture is an unresolved problem. A novel self-expandable biodegradable polydioxanon biliary stent in a porcine model was studied. MATERIALS AND METHODS This new stent was used in 23 pigs. Feasibility and safety of surgical stenting, time of biodegradation, and histologic reaction in 2, 8, 13, and 20 wk of a follow-up were studied. All stents were inserted into a common bile duct through a duodenal papilla following small dilatation. After surgical evaluation of abdominal cavities, the pigs were sacrificed to remove common bile ducts with the stents. All bile ducts were assessed by macroscopic and histopathologic examination. RESULTS Self-expansion was correct in all cases. Neither bile duct obstruction nor postsurgical complications were observed. Macroscopic evaluation indicated lightening of the stent color in 2 wk, a partial disintegration in 8 wk, and a complete absorption in 13 and 20 wk. Histologic evaluation in general substantiated a mild-to-moderate inflammatory reaction in the lamina propria during the whole follow up and had no clinical consequences. No cholangitis, necrosis, abscess, or excessive fibroplasia was found in a hepatoduodenal ligament. CONCLUSIONS Our results suggest that polydioxanon biodegradable self-expanding stents seem to be useful for biliary system implantation, offer a good biocompatibility, and completely degrade within 13 wk.

Abstract
Living donor liver transplantation (LDLT) has become an accepted therapeutic option for patients with end-stage liver disease. However, biliary complications remain the major causes of morbidity and mortality for LDLT recipients. Although there are currently no reports of a clear therapeutic algorithm, many approaches have been developed to treat biliary complications, including surgical, endoscopic, and percutaneous transhepatic techniques. Endoscopic treatment is currently the preferred initial treatment for patients that have previously undergone duct-to-duct biliary reconstruction. This article discusses aspects of endoscopic management of biliary complications that occur in adult LDLT.

Abstract
The authors suggest an original method of endobiliary stenting with laparoscopic assistance for reduction of obstructive jaundice in patients with non-operative tumors of hepatopancreaduodenal zone in the case of impossibility of performance of percutaneous or endoscopic decompression of the bile ducts. A recanalization of tumor stricture was carried out with the aid of laparoscopic assistance. A self-expandable metal stent with polymeric covering was implanted in the bile ducts. The proposed method was applied in 5 cases. An adequate decompression of the bile ducts was noted in all cases. The patient's condition was good after surgery. There weren't any cases of serious complications or hospital lethality.

Abstract
Hepatobiliary surgery is a challenging surgical subspecialty that requires highly specialized training and an adequate level of experience in order to be performed safely. As a result, minimally invasive hepatobiliary surgery has been met with slower acceptance as compared to other subspecialties, with many surgeons in the field still reluctant about the approach. On the other hand, gastric surgery is a very popular field of surgery with an extensive amount of literature especially regarding open and laparoscopic surgery but not much about the robotic approach especially for oncological disease. Recent development of the robotic platform has provided a tool able to overcome many of the limitations of conventional laparoscopic hepatobiliary surgery. Augmented dexterity enabled by the endowristed movements, software filtration of the surgeon's movements, and high-definition three-dimensional vision provided by the stereoscopic camera, allow for steady and careful dissection of the liver hilum structures, as well as prompt and precise endosuturing in cases of intraoperative bleeding. These advantages have fostered many centers to widen the indications for minimally invasive hepatobiliary and gastric surgery, with encouraging initial results. As one of the surgical groups that has performed the largest number of robot-assisted procedures worldwide, we provide a review of the state of the art in minimally invasive robot-assisted hepatobiliary and gastric surgery.The English full-text version of this article is available at SpringerLink (under supplemental).

Abstract
BACKGROUND Improvements in bile duct injury repairs have been shown in centres with specialized surgeons. The aim of the present study was to demonstrate the temporal change in the pattern of referral, technical variation associated with repair and long-term outcome of bile duct injuries at a tertiary referral centre in Mexico City. METHODS A retrospective case note review was performed. Patients were divided into two groups: group I (GI) 1990 to 2004 and group II (GII) 2005-2008, and appropriate statistical analysis undertaken. RESULTS Over a 20-year period, 312 patients with iatrogenic bile duct injuries required surgical treatment (GI = 169, GII = 140 patients). All injuries were reconstructed using a Roux-en-Y hepaticojejunostomy. The proportion of patients who had undergone a laparoscopic cholecystectomy increased from 24% to 36% (P = 0.017) over the two time periods. In the second time period there was an increase in segment IV and V partial resections (P = 0.020), a reduction in the use of transanastomotic stents (42% to 2%, P = 0.001) and an increase in the proportion of patients requiring a neoconfluence (2% to 11%, P = 0.003). In the second time period, the number of patients requiring a hepatectomy during repair (2% to 1%, P = 0.001), a portoenterostomy (16% to 9%, P = 0.060) or a double-barrel hepatico-jejunostomy (5% to 1%, P = 0.045) significantly decreased. During follow-up, patients in the second time period had a reduction in the incidence of post-operative cholangitis (11% to 6%, P = 0.310) and the frequency of post-operative anastomotic stenoses (13% to 5%, P = 0.010). Mortality remained low throughout the series but was absent in the second group. CONCLUSIONS Changes in technique and growing experience of the multidisciplinary team improved operative and long-term results of bile duct injury repair.

Abstract
BACKGROUND Although reports on endosonography-guided biliary drainage (ESBD) have been increasing, only a few discuss deployment of a self-expandable metal stent (SEMS) in the first session. OBJECTIVE To evaluate the safety and efficacy of ESBD with the one-step placement of a newly designed fully-covered SEMS. PATIENT AND METHODS Five patients with malignant biliary obstruction in whom one-step placement of an anti-migration designed SEMS in the first session of ESBD had been attempted between January 2007 and October 2009 were included in this study. Main outcome measurements were technical and clinical successes, early complications, and short-term results. RESULTS ESBD was attempted to bridge the extrahepatic bile duct and the duodenum and one-step SEMS placement was successful in all cases. There were no early complications related to ESBD and excellent biliary decompression was obtained in all cases. SEMS dysfunction such as stent migration and occlusion was not seen during the follow-up period (mean follow-up 138 days, range 102-184 days). CONCLUSION One-step placement of a fully-covered SEMS in ESBD is possibly a safe and effective treatment for biliary obstruction.

Abstract
OBJECTIVE To evaluate the efficacy of da Vinci surgical system in the treatment of biliary diseases. METHODS The clinical data of 15 patients with biliary diseases who had undergone operations with da Vinci surgical system from March 2009 to November 2009 at our hospital were retrospectively analyzed. RESULTS The operations were successfully performed on all patients. And no case was converted into open laparotomy. The total operative duration was 256 +/- 151 min and the robot operative duration 224 +/- 94 min. No blood transfusion was needed. Postoperative recovery time of bowl movement was 30 +/- 18 hours. And the average postoperative hospital stay was 6 +/- 3 days. Two patients had postoperative complications and were cured by conservative treatment. CONCLUSION Various laparoscopic operations for biliary diseases may be performed with the aid of three-dimensional imaging system and flexible surgical tools of the Da Vinci surgical system. And its superiority is more obvious for complicated biliary diseases.

Abstract
Endosonography-guided biliary drainage (ESBD) is a new method enabling internal drainage of an obstructed bile duct. However, the histological conditions associated with fistula development via the duodenum to the bile duct have not been reported. We performed ESBD 14 d preoperatively in a patient with an ampullary carcinoma and histologically confirmed changes in and around the fistula. The female patient developed no complications relevant to ESBD. Levels of serum bilirubin and hepatobiliary enzymes declined quickly, and pancreatoduodenectomy was carried out uneventfully. The resected specimen was sliced and stained with hematoxylin-eosin. Histological evaluation of the puncture site in the duodenum and bile-duct wall, and the sinus tract revealed no hematoma, bile leakage, or abscess in or around the sinus tract. Little sign of granulation, fibrosis, and inflammatory cell infiltration was observed. Although further large-scale confirmatory studies are needed, the findings here may encourage more active use of ESBD as a substitute for percutaneous transhepatic drainage in cases with failed/difficult endoscopic biliary stenting.

Abstract
PURPOSE To determine the application and clinical effectiveness of ePTFE/FEP-covered metallic stents for palliation of malignant biliary disease, and to evaluate the efficiency of stent coverage in preventing tumor ingrowth. METHODS During a 3-year period, 36 patients with malignant obstructive jaundice were treated with ePTFE/FEP-covered stents, with or without proximal side holes. The stricture was located in the lower common bile duct (CBD) in 18 cases, the upper CBD in 9, the lower common hepatic duct (CHD) in 6, and the upper CHD in 3 patients. RESULTS Thirty-seven covered stents were percutaneously implanted. The technical success rate was 97%. Reintervention was required in 6 cases. The 30-day mortality rate was 40%, not procedure-related. Mean survival was 128 days. Primary patency rates were 100%, 55.5%, and 25% at 3, 6, and 12 months, respectively, while the assisted patency rate was 100% at 12 months. Stents without side holes had higher primary patency rates compared with those with side holes, where occlusion was always due to tumor ingrowth. Tumor ingrowth did not occur in the completely covered stents. No stent dysfunction due to sludge incrustation was found. Complications were 1 case of arterial laceration that occurred during percutaneous transhepatic cholangiography, and a subcapsular hematoma and 1 case of bile peritonitis, that both occurred during primary stenting. No complications followed the secondary stenting technique. CONCLUSION ePTFE/FEP-covered metallic stents are safe and effective for palliation of malignant biliary disease. The presence of the ePTFE/FEP coating is likely to prevent from tumor ingrowth.

Abstract
PURPOSE To evaluate the effect of radiation therapy including intraluminal brachytherapy with iridium-192 on survival of patients with malignant biliary strictures (cholangiocarcinoma, histologically improved) treated with metallic stent in a prospective randomised study. METHOD AND MATERIALS In the prospective randomised study, 21 patients with cholangiocarcinoma were treated with implantation of percutaneous stents followed with intraluminal Ir-192 brachytherapy (mean dose 30 Gy) and external radiotherapy (mean dose 50 Gy) and 21 patients were treated only with stents insertion. We did not find any statistically significant differences in age and tumor localization between these two groups of patients. RESULTS All the patients died. In the group of patients treated with brachytherapy and with stent implantation, the mean survival time was 387.9 days. In the group of patients treated only with stent insertion the mean survival was 298 days. In effort to eliminate possible effect of external radiotherapy we treated the control group of eight patients with cholangiocarcinoma by stent insertion and brachytherapy only. CONCLUSION Our results show that combined radiation therapy could extend the survival in the patients with cholangiocarcinoma obstruction.

Abstract
The Mallory-Weiss Syndrome is a rare complication of endoscopic examination. Upper gastrointestinal bleeding due to the Mallory-Weiss Syndrome usually stops spontaneously. The gastroscopy is an effective procedure (method) of diagnosis and treatment of the syndrome. Presented in this paper is a case of 49-year old woman with an upper gastrointestinal bleeding due to the Mallory-Weiss after biliary prosthesis removal. The choledocholithiasis was the primary reason for the initial insertion of prostheses. The cause of gastrointestinal bleeding was determined on the basis of performed gastroscopy in the early stage of prostheses removal forced by bleeding. The bleeding was effectively stopped with endoclips.

Abstract
BACKGROUND Since 1990 we adopted the bilio-intestinal bypass (BIBP) for all morbid obese patients eligible to a malabsorption procedure. Since 2001 we used laparoscopic technique. MATERIALS AND METHODS 102 patients; mean age 35.4 (18-54) years; preoperative mean weight Kg 148.3 (105-225); mean preoperative BMI 54.1 kg/m2 (40-66.2); mean follow-up 10 years (1-22). 83 patients underwent open and 19 laparoscopic BIBP. The operation was performed with five lap ports. Section of the jejunum 30 cm from the Treitz and of mesentery was made by linear stapler. The cholecysto-jejunal anastomosis was completed with 45 mm linear stapler. A side-to-side anastomosis between the proximal jejunum and the last 12-18 cm of the ileum was created by firing a 60 mm linear stapler. On the excluded ileum an anti-reflux valve system was hand-sutured. RESULTS Five years post-operatively mean weight was 89 (62-130) kg, mean BMI was 31 (24-41) kg/m2. Two patients of the 19 laparoscopic patients were converted in open surgery for adhesions post-appendectomy. The main late complications were incisional hernia (19.3%) and abdominal bloating (2.9%). The reversal and conversion rate was 65%. There was no death. CONCLUSION Our experience showed that five years post-BIBP the weight loss was satisfactory in 90.7% of patients. Using laparoscopic technique it is possible to reduce pain, in-hospital time, respiratory and thromboembolic complications, convalescence and incisional hernia.

Abstract
BACKGROUND Percutaneous drainage or surgery is required when amebic liver abscess (ALA) fails to respond to medical management. In some of these patients, non-response may be due to communication of ALA with the biliary tree. This report describes our experience with the use of endoscopic biliary draining in such patients. METHODS Medical records of patients with ALA undergoing either needle aspiration or percutaneous pigtail drainage were retrieved; the indications for drainage were: abscess volume exceeding 250 mL, a thin rim of tissue (< 1 cm thick) around the abscess, systemic toxic features and failure to improve on medical treatment. Patients with abscess drain output >25 mL/day persisting for 2 weeks or presence of bile in the drain fluid underwent endoscopic biliary drainage. RESULTS A total of 115 patients with ALA underwent percutaneous treatment. None of the 25 patients with needle aspiration needed any further treatment. Of the 90 who underwent catheter drainage, the catheter could be removed within one week in 77 patients; the remaining 13 patients (median age 42 years, range 24-65; all men) had an abscess-biliary communication. In them, the median catheter output was 88 mL/day (range 45-347) and 54 mL/day (28-177) at 2 days and 2 weeks after catheter placement. The drain fluid contained bile in all 13 patients and in addition contained pus in 10 patients. Eleven patients had a solitary abscess and two had multiple abscesses. Cholangiogram showed biliary communication in all 13 patients. All patients were treated with placement of 10F biliary endoprosthesis or 10F nasobiliary drain. Pigtail catheter was removed within 1 week in 11 of 13 patients. CONCLUSION In patients with amebic liver abscess communicating with the biliary tree, biliary stenting may hasten clinical recovery and allow early removal of liver abscess catheter drain.

Abstract
Biliary reconstruction continues to be a major source of morbidity following liver transplantation. The spectrum of biliary complications is evolving due to the increasing number of split-liver and living-donor liver transplantation, which are even associated with a higher incidence of biliary complications. Bile duct strictures are the most common cause of late biliary complications and account for up to 40% of all biliary complications. Optimal therapy for posttransplantation anastomotic biliary strictures remains uncertain and requires a multidisciplinary approach. We report the case of a 54-year-old Caucasian male affected by hepatocarcinoma and hepatitis C-related cirrhosis who underwent right-lobe living-donor liver transplantation from his son complicated by double anastomotic stenosis of the main right hepatic duct and of an accessory biliary duct draining segments 6 and 7 of the graft that was successfully treated by percutaneous transhepatic cholangiography with long-term subcutaneous placement of two internal Rüsch-type biliary stents.

Abstract
Flexible endoscopy has evolved from a diagnostic tool practiced predominantly by gastroenterologists to a minimally invasive surgical tool. Therapeutic endoluminal procedures have become the standard of care for many gastric, biliary, pancreatic and colonic maladies. New technologies are under investigation for endoscopic treatment of gastroesophageal reflux, morbid obesity, and ablation of premalignant tissue. In the future flexible endoscopes may play a role in "natural orifice" surgery, performing operations through the mouth or rectum without the need for external incisions.

Abstract
This article reviews the current state of intraoperative ultrasonography in open surgery (IOUS) and laparoscopic surgery (LUS). The review is based on extensive study of data published (Pubmed search) and on 25 years of personal experience with intraoperative ultrasonography. The main application areas of IOUS and LUS and its use during liver, biliary tract, and pancreatic surgery are discussed. The benefits and limitations as well as future expectations with regard to the existing and emerging applications also are discussed. New developments in ultrasound technology and the increasing experience of surgeons in ultrasonography secure the future for IOUS and LUS.

Abstract
PURPOSE Reviewing the cases and evaluate the efficacity of the trans-tumoral drilling in the Klatskin tumours which were operated in Colentina Surgical Department. MATERIAL AND METHOD This is a clinical retrospective study on 109 cases of Klatskin tumours operated between 1998-2004. in 80 cases of them we could practice a biliary drainage using a trans-tumoral drilling. SURGICAL INDICATION: Malignant tumours of the main biliary duct developed at the level and above the junction of the two hepatic ducts , extended to the liver in many cases. SURGICAL TECHNIQUE Through the choledochostomy, we performed with a special instrument the trans-tumoral drilling with the setting of a biliary axial drainage (40 cases), external biliary drainage through a semirigid trans-choledochal tube (25 cases), Kehr tube (9 cases), U tube (3 cases), internal drainage with intra-choledochal stent (2 cases), lost tube (1 case). RESULTS In all cases we observed the early decrease of the jaundice. In the cases in which we used internal drainage, we had to perform a replacement of the closed tubes in 1-2 months after the first operation. Instead, the external biliary drainage, less expensive and periodically washed to preserve his permeability, proved his high efficiency. The average survival time was 8,9 months (between 5-20 months). CONCLUSIONS The external biliary drainage through trans-tumoral drilling remains in many cases the only one available therapeutical solution for the Klatskin tumours.

Abstract
BACKGROUND/PURPOSE The purpose of the present study was to investigate whether it was possible to use a vascular graft for reconstruction of the common bile duct (CBD) in pigs. METHODS Eight pigs, each weighing approximately 60 kg, were used for the experiments. The gallbladder was dissected and the cystic duct and cystic artery were ligated and divided. The CBD was displayed and divided. Then the CBD was reconstructed with a standard walled expanded polytetrafluoroethylene (ePTFE) vascular graft (internal diameter 4 mm) by means of 12 interrupted monofilament glycomer 63 (Biosyn) 4.0 sutures. The ends of the vascular graft were inserted into the CBD and the sutures were placed through the graft and the CBD in such a way that the latter would cover the former. The anastomotic line was covered by fibrin glue. On postoperative day 8, a laparotomy was performed; the pigs were investigated for signs of gall leakage, and cholangiography was performed. Blood samples for the determination of liver parameters were taken before the primary surgery and before the explorative laparotomy. RESULTS At evaluations on the eighth postoperative day, all animals except one were without signs of bile leakage. One pig had an encapsulated biloma. Another animal had to be operated on day 6 because of illness, and laparotomy showed a perforated gastric ulcer, but no bile leakage. Cholangiography revealed slight intrahepatic dilatation in all animals. Bilirubin and alkaline phosphatase levels were unaffected by the surgery. CONCLUSIONS Reconstruction of the CBD by means of a vascular graft seems to be a safe procedure in the short term in a pig model.

Abstract
Retained T-tubes are rare complications after biliary surgery. The authors present three cases of retained T-tubes in patients with transplanted liver that could not be removed by a standard manual traction. The authors describe a new simple percutaneous method that allows removal of these T-tubes without complication.

Abstract
BACKGROUND/AIMS To demonstrate the safety and feasibility of primary closure of the common bile duct (CBD) after laparoscopic choledochotomy in patients with CBD stones. Traditionally, the CBD is closed with T-tube drainage after choledochotomy and removal of CBD stones. However, the insertion of a T-tube is not without complication and the patients have to carry it for several weeks before removal. In the laparoscopic era, surgery is performed with minimally invasive techniques in order to reduce the trauma inflicted on patients, hasten their recovery and hence reduce the hospital stay. T-tube insertion seems to negate these benefits and we believe that primary closure can be as safe as closure with T-tube drainage. METHODOLOGY This is a retrospective analysis of patients who underwent primary closure of the CBD after successful laparoscopic choledochotomy for ductal stones between January 2000 and December 2003. A concurrent control group of patients who underwent T-tube drainage was used for comparison. RESULTS Of the 64 patients that underwent laparoscopic exploration of the CBD, 24 (37%) underwent transcystic duct approach and 40 (63%) underwent choledochotomy. There were three open conversions (5%). Stone clearance was achieved in all patients with successful laparoscopic choledochotomy (100%). Of the 38 successful laparoscopic choledochotomies, 12 had primary closure of the CBD and 26 had closure with T-tube drainage. There was no mortality in both groups. One patient in the primary closure group suffered from paralytic ileus and small subhepatic collection which was treated conservatively. The median operative time (90 vs. 120 minutes, p=0.002) and postoperative stay (5 vs. 8.5 days, p=0.003) were shorter in the primary closure group when compared with the T-tube group. CONCLUSIONS Primary closure of the CBD is feasible and as safe as T-tube insertion after laparoscopic choledochotomy for stone disease.

Abstract
BACKGROUND AND STUDY AIMS The JoStent SelfX is a new biliary uncovered self-expanding nitinol stent. The main advantage of this stent in comparison with the "gold standard" Wallstent is the minimal shortening (< 10 %) that occurs during stent deployment. A prospective feasibility study was conducted to evaluate the method of stent implantation and the stent's short-term efficacy. PATIENTS AND METHODS Between April 2001 and December 2002, the JoStent SelfX was implanted in 20 patients with inoperable malignant biliary obstructions, mainly caused by pancreatic cancer (12 of 20). All patients underwent sphincterotomy prior to stent insertion. After implantation, laboratory parameters for cholestasis and expansion of the stent were checked over a period of several days. All patients were followed for 8 weeks after implantation to document early stent dysfunction. RESULTS Stent implantation was easily managed and successful in all patients, with no technical problems. Prior bougienage was required in only one patient, who had a filiform stenosis. No stent retraction was observed during stent release. All stents showed full expansion within 5 days. No acute complications occurred. Adequate reduction in the elevated laboratory parameters for cholestasis was observed. Two patients had recurrent cholestasis and fever due to cholangitis, or stent occlusion caused by biliary sludge within 4 weeks. CONCLUSIONS This new biliary metal stent is easily inserted and does not shorten during stent release, allowing precise positioning. No acute complications occurred, but there were two cases of early stent dysfunction. The role of the JoStent SelfX in comparison with other biliary stents will need to be evaluated in a multicenter trial with a larger number of patients, to investigate the long-term results.

Abstract
BACKGROUND/AIMS The conventional transhepatic biliary drainage method requires a long period of tube placement and a technically difficult intubation. METHODOLOGY New transhepatic biliary drainage methods were applied in cases undergoing an open choledochotomy. The drainage tube was placed transhepatically using a newly developed, rigid and J-shaped needle (J-Needle) with a vertical, ventral and rotating penetration at the proximal hepatic duct. The tube was then introduced directly to the extraperitoneal space by attaching the parietal peritoneum to the liver surface without tube-fixation (extraperitoneal transhepatic tube method). RESULTS These procedures were applied in 50 patients. The J-Needle was easily and safely inserted without any complications. In the 39 analyzed cases, the patients were safely extubated on postoperative day 7 and discharged around postoperative day 10. CONCLUSIONS The combination of the J-Needle and the extraperitoneal transhepatic tube method is useful for safe transhepatic biliary intubation and early extubation, enabling a shorter hospital stay for patients requiring biliary surgery.

Abstract
PURPOSE The segmental resection of constricted bile duct and end-to-end biliary anastomosis could be an attractive alternative in the treatment of benign biliary tract stricture. The aim of this study was to restore the anatomical integrity of the hepatic-common bile duct after an artificially produced defect while maintaining the large duodenal papilla, using microsurgical technique. MATERIAL AND METHODS The experiments were carried out on 25 mongrel dogs. The common bile duct was ligated in all of the animals during laparotomy, as a model of bile duct obstruction in humans. Relaparotomy was performed 3 days after the initial operation. The segment of bile duct, 4 cm in length was resected together with the ligature. The continuous bile flow into the duodenum was assured by a polyvinyl catheter introduced into both ends of dissected bile duct. The proximal end of the hepatic-common bile duct was fixed to a device constructed by us for the distention of the bile duct (DDBD). The anterior part of the device was exteriorized through a separate fistula and fixed to the abdominal wall. The hepatic-common bile duct distention was gradually continued during 18 days, by pulling out the mobile part of the device. After 18 days the device was removed and the distended proximal end of the hepatic-common bile duct was anastomosed end-to-end with its distal end. The sequels of this procedure were observed for up to 6 months. RESULTS The hepatic-common bile duct was distended 4 cm within 18 days. The histopathological examination has shown partial damage of the duct framework due to the distention and tension. However the patency of the duct was preserved and the recovery of normal structures were observed after the device was removed and anastomosis fashioned. CONCLUSION This method, developed by us, offers the possibility of restoring the integrity of injured extrahepatic bile ducts, allowing effective treatment of benign biliary strictures.

Abstract
We describe transcystic common bile duct (CBD) stone extraction using Dormia basket in patients with preoperatively unexpected CBD stones during laparoscopic cholecystectomy (LC). We perform intraoperative cholangiography (IOC) selectively. Stone extraction was successful five times and we converted to open procedure in one patient because of the size of the stone. Mild postoperative acute pancreatitis developed once. No other complication was detected. Procedures performed if CBD stone is detected intraoperatively are evaluated in the article, including indications and difficulties of the Dormia basket method. We suggest the introduction of the method as an alternative treatment for unexpected CBD stones during laparoscopic cholecystectomy.

Abstract
The ultrasonically activated scalpel, a new tool for cutting and coagulating tissue, uses high-frequency ultrasonic vibrations, and has been widely employed in the field of laparoscopic surgery. We evaluated its usefulness for cutting the pancreas in biliary-pancreatic surgery. We planned experimental and clinical studies using an ultrasonically activated scalpel (harmonic scalpel) for cutting the pancreas. The harmonic scalpel was set up at a power level of 3 (75% of full power) in the knife mode. In the experimental study, using dogs, cutting of the pancreas with the harmonic scalpel resulted in significantly less bleeding and significantly less histological tissue damage to the cut stumps than cutting of the pancreas with an electric or a regular scalpel. In the clinical study: (1) the hemostatic effect of the harmonic scalpel was excellent or good in any condition of the pancreas; (2) of 50 stumps of the main pancreatic duct cut with the harmonic scalpel, the stump was easily found in 48 (96%), while ultrasonography was necessary to find the remaining 2 stumps in soft pancreas; (3) in 41 anastomoses (29 soft and 12 hard pancreas) there were no postoperative pancreatic fistulae. These results indicate that the ultrasonically activated scalpel is an effective tool for cutting the pancreas in biliary-pancreatic surgery.

Abstract
Primary bile duct closure with retrograde transhepatic biliary drainage (RTBD) using an RTBD tube (RTBDT) is a feasible surgical technique after common bile duct exploration in choledocholithiasis in comparison to conventional T-tube insertion. But, unfortunately, this technique is not popular because of the difficulty to introduce a catheter into a proposed intrahepatic bile duct branch without hepatic injury. In addition, the time for its safe removal is not shorter than that with T-tube insertion. So, we have devised a special needle-attached RTBDT (n-RTBDT) to guide the tube via the intrahepatic bile duct of the liver with minimal hepatic injury, and proposed a new surgical technique, namely extraperitoneal RTBD (Ep-RTBD), using the n-RTBDT providing earlier removal without fistula formation in the general peritoneal cavity. In all patients with common bile duct calculi who underwent this surgical procedure, the tube could be revoved within 10 postoperative days with no complication.

Abstract
Comparative estimation of the native microsurgical atraumatic suture material metallatraum and the foreign threads (prolene and virgin silk) application while the biliobiliary and biliodigestive anastomoses formation was done in experiment. Most favourable tissue reaction was noted using monolithic threads prolene and metallatraum. Metallatraum thread is the most resistant one to the calculi deposition on it. The silk thread application in biliary ducts surgery is not indicated.

Abstract
OBJECTIVE To test in vitro stents made from a new biomaterial that is less liable to encourage adhesion of bacteria that may lead to blockage of the stent. DESIGN Laboratory experiment. SETTING University hospital, Italy. MATERIAL 15 polyethylene biliary endoprostheses that had been removed endoscopically a mean of 151 days (range 55416) after insertion. PUPA, a biomaterial that contains polyamidoamine cross-linked to polyurethane chains. This can bind large quantities of heparin and HyalSx (hyaluronic acid at a different stage of sulphation) in a stable fashion. MAIN OUTCOME MEASURES Incidence of blockage and growth of pathogens in the polyethylene biliary prostheses. Adhesion of pathogens to PUPA in vitro on electron microscopy. RESULTS 12 of 15 polyethylene prostheses were blocked by brown concretions composed of calcium bilirubinate, palmitate, and little cholesterol. All concretions grew more than one pathogen, and the growth always included Escherichia coli. Of the 5 PUPA stents tested, only 1 had bacteria sticking to their surfaces. CONCLUSION These results confirm previous studies that showed that HyalSx appreciably inhibited the adhesion of bacteria and is therefore a suitable material for the manufacture of biliary stents.

Abstract
Intraoperative sonography (I.O.S.) with the use of high-frequency probes placed in direct contact with structures in exploration assures a more diagnostic accuracy. I.O.S. is particularly useful in bilio-pancreatic surgery for a more precise diagnostic valuation and an excellent surgical approach. It is fundamental in the lithiasis of the biliary duct, especially hepatic lithiasis, microlithiasis, obstruction of common bile duct of uncertain cause and during laparocholecystectomy. In pancreatic surgery I.O.S. is of great usefulness in the study of acute and chronic pancreatitis and their complications, cysts, pseudocysts and cystic tumors. I.O.S. plays important role both in exocrine pancreatic carcinomas for a correct staging, and resectability decision, and in endocrine functioning tumors, permitting the location of some lesions of little dimension and eventual hormone secreting hepatic or lymph nodal metastases. In laparoscopic mini-invasive surgery, I.O.S. substitutes the palpatory sense of touch in the location and study of anatomic structures, reducing the risks of iatrogenic lesions and allowing, diagnostic accuracy even in some underestimated pathologies.

Abstract
BACKGROUND Biliary sludge which forms as a result of bacterial adherence and biofilm formation in the biliary system is a recognized cause of blockage of plastic stents. Bacteriological cultures of sludge have revealed a mixed infection with gram-positive and gram-negative bacteria. Animal studies have shown that prophylactic ciprofloxacin, which selectively suppress gram-negative bacteria, results in prolonged stent patency despite colonization of the stents by gram-positive bacteria. METHODS We tested a possible synergistic effect between gram-negative and gram-positive bacteria in adherence and biofilm formation on plastic stents. Clinical isolates of Escherichia coli and Enterococcus were cultured in separate chemostats to achieve a steady growth. Adherence of the two bacteria on plastic stent surface were tested separately by perfusing infected bile with the respective bacteria through different modified Robbins devices containing 10F polyethylene stent pieces up to 4 days. In a second experiment, Enterococcus was perfused through stent pieces precolonized with E. coli for 24 hours. The stent pieces were then removed daily and analyzed by bacteriologic culture and scanning electron microscopy for bacterial adherence and biofilm formation. RESULTS Gram-negative E. coli were more adherent than gram-positive Enterococcus. Precolonization with E. coli facilitates subsequent attachment of Enterococcus. CONCLUSIONS We concluded that there is a synergistic effect between gram-positive and gram-negative bacteria in adherence and biofilm formation.

Abstract
BACKGROUND AND STUDY AIMS Endoscopic biliary stenting is often used for large or difficult common bile duct (CBD) stones that cannot be extracted at one session. We compared the sizes of the CBD stones after a period of stenting. PATIENTS AND METHODS Over a 6-year period, a total of 444 patients with large CBD stones (> 2 cm diameter) or difficult CBD stones were managed in our endoscopy unit, of which 46 were treated by endoscopic stenting. Twenty-eight had second ERCP for stone removal after a median period of 63 days (range 17-1002 days). The largest diameter of the stones and the CBD (after correction of magnification) before and after stenting were compared using the Wilcoxon signed test. RESULTS Before stenting the largest diameters of CBD stones were 11-46 mm (mean 24.9 mm) and decreased to 5-46 mm (mean 20.1 mm) after stenting. The difference in stone sizes was statistically significant although the CBD diameter pre- and post-stenting was not significantly different. The reduction in stone sizes was not significantly correlated with the duration of stenting. CONCLUSION CBD stones became smaller after stenting. As the difficulty of stone extraction increases with stone size, a period of stenting may make subsequent removal easier for patients with large or difficult CBD stones.

Abstract
BACKGROUND AND STUDY AIMS The biliary stents in current use have a tendency to be blocked, so we designed a self-expandable metal stent covered with polyurethane to overcome the risk of tumor ingrowth of uncovered self-expandable metal stents. To evaluate the success and the effectiveness of the new membrane-covered self-expandable metal stent (covered modified Gianturco biliary stent), we studied patients with biliary obstruction caused by biliopancreatic carcinoma. PATIENTS AND METHODS We retrospectively evaluated 47 patients with malignant biliary obstruction to receive either a newly developed self-expandable metal stent covered with polyurethane (21 cases) or an uncovered metal stent (Strecker stent or Wallstent, 26 cases) by the endoscopic transpapillary route. RESULTS The success rate of stent insertion and drainage effect of stent showed no statistical difference in patients with a new membrane-covered self-expandable metal stent compared with those with an uncovered metal stent (90.4% vs. 88.5%, P > 0.05; and 100% vs. 95.6%, P > 0.05, respectively). The median patency of the stent was slightly prolonged in patients with a membrane-covered self-expandable metal stent, but there was no statistical difference between two groups (267 vs. 233 days, P > 0.05). The rate of early complication related to stent insertion showed no significant difference between the two groups. During the follow-up period, stent occlusion due to tumor ingrowth occurred in two patients (10.5%) in the membrane-covered, self-expandable stent group, compared with six patients (26.1%) in the uncovered metal stent group. The membrane-covered metal stent was removed successfully and a polyethylene stent was reinserted in one patient who had developed tumor overgrowth. CONCLUSIONS A new, membrane-covered, self-expandable metal stent has a tendency towards better long-term patency than the uncovered metal stent, and it can effectively prevent tumor ingrowth into the stent. Also it is possible to remove an occluded membrane-covered stent. However, a case-controlled study, including a larger patient number, and long-term follow-up are needed.

Abstract
A specially designed surgical drainage for biliary tracts provides safe fixation and easy and minimally traumatic removal. There are no conditions for internal rotation of the tube, and the presence of a few openings in an active part of the drainage in combination with two channels prevent disorders of the drainage function in case of clogging of some of the openings. An opportunity to control the working shape during the removal of the drainage is considered to be its important advantage. The drainage can be adyiested to the shape of hepaticocholedoch. Besides, there is an opportunity of unloading the terminal part of choledoch and evacuating the regurgitation of a pancreatic secret. The design of the drainage prevents narrowing of the choledoch in the region of choledochotomy opening. The proposed variant of the drainage can be easily created in any operating room.
