ABSTRACT
Objective:To investigate the clinical efficacy of modified biliary-intestinal anasto-mosis by pancreaticoduodenectomy and influencing factors of postoperative biliary leakage.Methods:The propensity score matching and retrospective cohort study was conducted. The clinicopatholo-gical data of 165 patients with benign and malignant diseases around the ampullary who underwent pancreaticoduodenectomy in the Affiliated Hospital of Inner Mongolia Medical University from June 2014 to October 2020 were collected. There were 92 males and 73 females, aged (59±10)years. Of the 165 patients, 44 patients undergoing modified biliary-intestinal anastomosis within pancreatico-duodenectomy were divided into the modified group, and 121 patients undergoing traditional biliary-intestinal anastomosis within pancreaticoduodenectomy were divided into the traditional group. Observation indicators: (1) propensity score matching and comparison of general data of patients between the two groups after matching; (2) intraoperative and postoperative situations; (3) analysis of influencing factors of biliary leakage after pancreaticoduodenectomy. Propensity score matching was done by the 1:1 nearest neighbor matching method, with the caliper setting as 0.05. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Univariate analysis was conducted using the corresponding statistical methods based on data type. All indicators in univariate analysis were included in multivariate analysis. Multivariate analysis was conducted using the Logistic regression model. Results:(1) Propensity score matching and comparison of general data of patients between the two groups after matching. Of the 165 patients, 72 cases were successfully matched, including 36 cases in the modified group and 36 cases in the traditional group, respectively. The elimination of jaundice, preoperative reduction of jaundice and hypertension confounding bias ensured comparability between the two groups after propensity score matching. (2) Intraoperative and postoperative situations. All patients in the two groups underwent surgery successfully. The operation time, postoperative pathological type (lower bile duct cancer, pancreatic head cancer, pancreatic cystic tumor, chronic pancreatitis, duodenal cancer), time of no drainage fluid in the drainage tube around biliary-intestinal anastomosis were 371(270,545)minutes, 6, 12, 1, 2, 15, (12±7)days in patients of the modified group, versus 314(182,483) minutes, 13, 14, 1, 4, 4, (16±8)days in patients of the traditional group, showing significant differences in the above indicators between the two groups ( Z=-3.54, χ2=10.01, t=-2.34, P<0.05). Cases with postoperative grade A biliary leakage was 0 in patients of the modified group, versus 6 in patients of the traditional group, showing a significant difference between the two groups ( P<0.05). Cases with postoperative grade B biliary leakage, cases with postoperative grade B pancreatic fistula, cases with postoperative bleeding, cases with abdominal infection, cases with incision infection, cases with delayed gastric emptying, cases undergoing unplanned readmission were 1, 0, 1, 4, 1, 5, 1 in patients of the modified group, versus 0, 1, 2, 5, 2, 5, 2 in patients of the traditional group, showing no significant difference in the above indicators between the two groups ( P>0.05). Cases with postoperative grade A pancreatic fistula, cases with overall complications, cases with Clavien-Dindo grade Ⅰ-Ⅱ complications, cases with Clavien-Dindo grade Ⅲ-Ⅳ complications were 6, 12, 6, 6 in patients of the modified group, versus 7, 14, 8, 6 in patients of the traditional group, showing no significant difference in the above indicators between the two groups ( χ2=0.09, 0.24, 0.36, 0.00, P>0.05). None of patient in the two groups had postoperative grade C biliary leakage and postoperative grade C pancreatic fistula. (3) Analysis of influencing factors of biliary leakage after pancreaticoduodenectomy. Results of multivariate analysis showed that preoperative reduction of jaundice and traditional biliary-intestinal anastomosis were independent risk factors for biliary leakage after pancreaticoduodenectomy ( odds ratio=11.37, 12.27, 95% confidence interval as 1.76-73.35, 1.14-131.23, P<0.05). Conclusions:Compared with traditional biliary-intestinal anastomosis, modified biliary-intestinal anastomosis within pancreaticoduodenectomy is safe and feasible. Preoperative reduction of jaundice and traditional biliary-intestinal anastomosis are independent risk factors for biliary leakage after pancreaticoduodenectomy.
ABSTRACT
Objective:To analyse the risk factors of biliary leakage after surgical resection in patients with perihilar cholangiocarcinoma (PHCC).Methods:The medical data on 179 patients who underwent surgical resection for PHCC at the Department of Hepatopancreatobiliary Surgery, Ningbo Medical Centre Lihuili Hospital, Ningbo University from April 2000 to April 2020 were collected, and 160 patients were finally enrolled into this study. There were 86 males and 74 females, aged (63.4±10.8) years. The 44 patients with class B biliary leakage and the 5 patients with class C biliary leakage were classified into the biliary leakage group, while the remaining 111 patients were classified into the control group. Risk factors of biliary leakage were analysed by univariate and multivariate logistic regression analyses.Results:Operation time ≥360 min, resection and reconstruction of hepatic hilar vessels on the preserved side of liver and number of bile duct openings of >3 in remnant liver were significantly higher in the biliary leakage than the control group (all P<0.05). Multivariate analysis showed that resection and reconstruction of hepatic hilar vessels on the preserved side ( OR=2.322, 95% CI: 1.078-5.002, P=0.028) and 3 or more bile duct openings in the remnant liver ( OR=2.656, 95% CI: 1.198-5.892, P=0.016) were significantly associated with biliary leakage. Conclusion:Resection and reconstruction of hepatic hilar vessels on the preserved side of liver and 3 or more bile duct openings in remnant liver were independent risk factors for biliary leakage after PHCC resection.
ABSTRACT
Background: Liver trauma is the most commonly observed injured organ in abdominal trauma. The objectives of this study was to determine and evaluate the rates of complication in the management of liver traumaMethods: This cross-sectional observational study using non-probability convenient sampling technique was done at surgical unit of Liaquat University of Medical and Health Sciences, Jamshoro, for 06 months. After ethical approval from Institute’s Institutional Review Board (IRB), patients presenting to surgical emergency of the hospital between ages 16 to 60 years having blunt or penetrating liver trauma within 04 hours of incident, either road traffic accident, sustaining a fall, sporting injury, knife or stab wound were include while patients of liver trauma conservatively managed or had severe co-morbid, not fit for anesthesia, with multiple organs lesions (polytrauma) and all hepatic injury patients that were hemo-dynamically stable were excluded. SPSS version 23 was used for data analysis keeping p-value <0.05 as significant.Results: Among 136 patients with mean age 32.33±11.23 years, 120(88.2%) were males. 122(89.7%) of the patients were admitted due to liver trauma of blunt variety while 14(10%) with penetrating liver injury. Overall mean duration of hospital stay was 13.1±4.58 days. 41(30%) patients reported intra-abdominal sepsis, followed by recurrent hemorrhage in 33(24%) of patients while in 22(16%) of patients, biliary leakage was observed. An insignificant difference persisted in either surgical intervention in terms of the complication rates.Conclusions: Higher complication rates were observed in patients with peri-hepatic packing, however outcome of both surgical techniques in terms of complication rates were found to be insignificant. Further studies are needed to shed light upon the findings or this study.
ABSTRACT
Objective To establish a modified dual liver transplantation rat model. Methods Based on the classic donor Y-shaped double iliac vein recanalization of bilateral liver grafts and portal vein and bile duct of the recipients, the dual liver transplantation rat model was modified by increasing the rat body mass, increasing the right lower lobe of the right graft, appropriate bile duct length, trimming Y-shaped blood vessels, and "triangular" anastomosis. The operation time, cold ischemia time, warm ischemia time and anhepatic phase of dual liver transplantation were recorded. The incidence of postoperative complications of the recipients was observed. The survival rates of the recipients at postoperative 7 and 30 d were calculated. Results The operation time of dual liver transplantation in rat was (114±7) min, the cold ischemia time was (36±3) min, the warm ischemia time was (9.7±1.6) min, and the anhepatic phase was (19.9±2.2) min, respectively. The incidence of postoperative complications in the recipient rats was 31% (5/16) including 2 cases of peritoneal effusion, 1 case of hemorrhage, 1 case of bile leakage and 1 case of respiratory obstruction. The postoperative 7- and 30-d survival rates of the recipient rats were 81%(13/16)、56%(9/16), respectively. Conclusions The modified technique can establish a stable dual liver transplantation rat model, which deserves widespread application.
ABSTRACT
Objective To investigate the indication and clinical experience of laparoscopic subtotal cholecystectomy. Methods We performed a retrospective analysis on the clinical data of 468 patients who underwent laparoscopic subtotal cholecystectomy from January 2012 to December 2015. Results There were no deaths. 7 cases that underwent laparoscopic cholecystectomy were converted to open surgery with laparoscopic subtotal cholecystectomy. 5 cases that were diagnosed with Mirizzi syndrome (3 cases with type I and 2 with type II) and 456 cases underwent laparoscopic subtotal cholecystectomy. No severe complication was detected after surgery. 16 cases with biliary leakage and 2 with duodenum leakage. The patients got recovered after a short time of drainage. 362 cases were followed up and the median follow-up time was (21.0 ± 4.9) months. 18 ones were with dyspepsia and 11 ones with upper or right upper discomfort. Conclusion Laparoscopic subtotal cholecystectomy was a safe choice and avoided injury of biliary duct for patients with severe adhesion of calot's triangle. The biliary leakage should be mainly observed during and after surgery.

ABSTRACT
Background: Cholecystectomy is one of the most frequently performed surgeries. The surgery is associated with many avoidable complications and hence requires a serious and cautious approach. Aim: The aim of this study was to know the outcome of post cholecystectomy biliary leaks and its management methods. Materials and methods: 10 cases of biliary leaks were studied from 100 open cholecystectomies and 100 laparoscopic cholecystectomies from 2013 January to 2014 January. Pre-operative workup with ultrasound abdomen, LFT and other biochemical investigations were done and diagnosis was established. The outcome of surgery and its most common post-operative complication - biliary leak was studied with following parameters: Post-operative diagnosis, Surgery - Lap or Open, Incision, Method of approach – Fundus or Classical method, CBD exploration, Intra-operative findings, Drains used, Post-operative symptoms, Amount of collections, Removal of drains, USG – Sub hepatic collections, ERCP etc. Results: In the present study of 10 cases, fundus first method was done in 3 cases of open cholecystectomies and none in laparoscopic cholecystectomies. Classical procedure was done in 7 cases out of which 3 cases were done in laparoscopy method and 16 cases in open method. Intraoperative detection of bile duct injury is noted in 3 cases of open cholecystectomies and non in laparoscopic method. In the present study, 56 % of the patients were treated conservatively who required no therapy and surgical placement of the drain itself was sufficient. P. Krishna Kishore, B. Manju Sruthi, G. Obulesu. Study of post cholecystectomy biliary leakage and its management. IAIM, 2016; 3(9): 222-227. Page 223 Conclusion: Pain abdomen, Jaundice, Nausea and Vomiting are the major complaints in case of bile leaks and fistulas. Pathologically, chronic cholecystitis is commonest cause of leaks after surgery mainly because of fibrosis at calots triangle. Incidence of Post-operative bile leaks is almost the same in open and laparoscopic cholecystectomy. Routine placement of drains is must because it permits post operative evacuation of serosanguineous exudates and monitoring of bleeding or leakage of bile. Abdominal collections, bilomas or sub-hepatic abscess are reported less with the placement of drains
ABSTRACT
SUMMARY OF EVENT: Persistent greenish discharge with abdominal pain and fever were developed in the patient who had undergone laparoscopic cholecystectomy. For the endoscopic treatment of postoperative bile leak, endoscopic biliary sphincterotomy (EBST) with endoscopic retrograde biliary drainage (ERBD) was done and patient's symptoms and persistent discharge via surgical drain were resolved. TEACHING POINT: A high grade bile leak suggests a large defect and EBST alone may be insufficient to allow healing of the defect, and thus, ERBD with or without EBST is proposed as the preferred initial endoscopic treatment.

A biloma is a rare abnormal accumulation of intrahepatic or extrahepatic bile caused by a traumatic or spontaneous rupture of the biliary tree. The reported incidence of postoperative biloma ranges from 4.8% to 7.6%. Biliary drainage is usually important and necessary for the treatment of biloma, but sometimes bile leakage fails to improve despite prolonged conservative drainage. We report a case of postoperative refractory biliary leakage managed with percutaneous ablation by N-butyl cyanoacrylate.

Introducción: Las complicaciones del tracto biliar posteriores al trasplante ortotópico de hígado (TOH) son uno de los problemas más importantes, ya que pueden ocasionar disfunción del injerto y muerte. Objetivo: Evaluar la incidencia de las complicaciones biliares posteriores al TOH en la serie de nuestra institución. Metodología: De forma retrospectiva se evaluaron las historias clínicas de 254 pacientes a quienes se les realizó TOH con donante cadavérico y se identificaron aquellos pacientes que presentaron complicaciones biliares. Resultados: Se documentaron 25 pacientes con complicaciones biliares, para una frecuencia de 9,84%; 21 casos (84%) de estenosis biliar, de estos, 16 (64%) estenosis anastomóticas y 5 (20%) estenosis no anastomóticas. Hubo 7 casos (28%) de fugas biliares. Otras complicaciones fueron menos frecuentes. La sobrevida es de 88% con una media de seguimiento de 37,8 meses. Conclusión: Las complicaciones biliares pos-TOH continúan siendo frecuentes, sin embargo, el desarrollo en las técnicas de intervención endoscópica y percutánea han mejorado el pronóstico general de estos pacientes.
Introduction: Biliary duct complications following an orthotopic liver transplant (OLT) are some of the most important problems since they can cause graft dysfunction and death. Objective: Evaluate the incidence level of biliary complications following OLTs in our institution. Methodology: The clinical charts of 254 patients who had had OLTs with deceased liver donors were retrospectively evaluated to identify those who developed biliary complications. Results: 25 patients with biliary complications, or a frequency of 9.84%, were documented. 21 cases (84%) had biliary strictures. Of these 16 (64%) had anastomotic strictures and 5 (20%) had non-anastomotic strictures. There were 7 cases (28%) of biliary leakage. Other complications were less frequent. The survival rate is 88% with mean follow up time of 37.8 months. Conclusion: Post OLT biliary complications are still frequent; however, the development of endoscopic and percutaneous interventions has improved the general prognosis of these patients.

Objective To explore for the methede and effect of endoscopic treatment on biliary leakage and biliary duct damage. Methods All patients with biliary damage such as biliary leakage and biliary duct stricture were treated by endoscopic sphincoterotomy and endoscopic nasobiliary drainage (ENBD) during abdominal cavity drainage ENBD was removd when biliary leakage healed and abdominal cavity drainage ceased for 1～2 weeks were confirmed. Plastic stents were implanted to distend the biliary duct stricture for 2-3 months. Results Twenty-six patients with biliary leakage were cured 3-4 weeks after ENBD. Fourteen out of 17 patients implanted with plastic stent were recovered uneventfully after stent removed, and 4 patients also recovered after installation of double-stents for 3 months, while another case with calculus and stricture of left hepatic duct in spite of implantation of simple-stent suffered repeatedly from biliary tract infection and one case developed hepatic abscess after repeatedly infection for one year before he had the hepatic lobectomy. Conclution Endoscopic therapy is the first choice in treating biliary leakage or secondary duct stricture.
ABSTRACT
Objective To observe prospectively the role of endoscopic diagnosis and treatment of biliary leakages in patients with liver transplantation, and the incidence of bile duct stricture after healing of the leakage. Methods Six eases of T-tube leakage and seven cases of anastomosis leakage complicating liver transplantation were enrolled in this prospective study. Six patients treated by endoscopic plastic stent placement , 2 by naso-biliary catheter drainage, 2 by papillosphincterotomy and 3 by naso-biliary catheter drainage combined with plastic stent placement. Some patients received growth hormone treatment. Results The bile leak resolution time was between 10-35 days in 10 patients with complete document. The median time of leak resolution was 15. 3 days. Four cases of anastomosis stricture, three cases of common hepatic duct and one ease of multiple bile duct stenosis were observed by followed-up nasobiliary catheter cholangiography or ER-CP. Conclusion Endoscopic nasobiliary catheter or plastic stent placement is a safe and effective treatment for bile duct stricture occurred after bile leak resolution in most of liver transplantation patients. Naso-biliary catheter combined with plastic stent placement maybe the best choice for treating bile leak, because, theoretically, it may prevent serious condition happened at accidental nasobiliary catheter dislocation, and it may have prophylactic effect on upcoming bile duct stricture and should be further confirmed.
