RESUMO
Objective To discuss the application effect of using a stone extractor balloon catheter to assist in crossing the anastomotic stenosis in treatment of anastomotic biliary stenosis after liver transplantation using endoscopic retrograde cholangiopancreatography(ERCP).Methods Clinical data of 48 patients who developed anastomotic biliary stenosis after liver transplantation and underwent ERCP treatment were collected.Upon unsuccessful use of a dilation catheter to cross the stricture,attempts were made to cross the anastomotic biliary stenosis by using a stone extractor balloon catheter.The success rate of the procedure was recorded,intraoperative conditions were observed,treatment outcomes and complications were analyzed.Results The main presenting symptoms in the 48 patients on admission were abdominal discomfort(32 patients),fever(7 patients),pruritus(4 patients),jaundice(3 patients),and no obvious symptoms(2 patients).Preoperative magnetic resonance cholangiopancreatography(MRCP)examination revealed isolated stricture of the anastomotic site in 35 cases,and stricture associated with stones in 13 cases.Using the stone extractor balloon catheter as a guide,guidewire crossing of the anastomotic stenosis was successful in 26 cases,resulting in a success rate of 54.17%(26/48).Through statistical analysis of the successful group and the failed group,there was a significant difference in whether the distal biliary dilatation between the two groups,and the difference was statistically significant(χ2 = 8.39,P = 0.004).In the 26 successfully treated cases,alanine transaminase(ALT),aspartate transaminase(AST),γ-glutamyl transpeptidase(γ-GT),alkaline phosphatase(ALP),and total bilirubin(TBiL)levels decreased significantly 48 hours after the procedure(P<0.05),and no serious complications occurred.Conclusion The use of a stone extractor balloon catheter significantly increases the success rate of crossing anastomotic stenosis in the treatment of anastomotic biliary stenosis after liver transplantation,especially in cases with distal dilatation of the common bile duct.This approach is safe and worth promoting.
RESUMO
Objective To evaluate the application efficacy of SpyGlass endoscopic direct visualization system in management of complex biliary complications after orthotopic liver transplantation. Methods Clinical data of 369 adult patients with biliary complications after orthotopic liver transplantation who received endoscopic retrograde cholangiopancreatography (ERCP) for the first time were retrospectively analyzed. Preoperative conditions, intraoperative manifestations, treatment outcomes and complications of patients treated with SpyGlass system were analyzed. Results Fifty-six patients were treated with SpyGlass system. The main preoperative symptoms included abdominal discomfort in 38 cases, fever in 8 cases, jaundice in 6 cases and skin itching in 4 cases. Ultrasound examination in 18 patients indicated common bile duct stenosis and significant intrahepatic bile duct dilatation. Preoperative magnetic resonance cholangiopancreatography (MRCP) of 56 patients revealed that 36 cases were diagnosed with common bile duct stenosis complicated with stones, 16 cases of common bile duct stenosis alone and 4 cases of suspected tumors. All patients had definite indications for SpyGlass system treatment. Among 56 patients treated with SpyGlass system, 34 cases were diagnosed with anastomotic stricture complicated with stones, 12 cases of anastomotic stricture alone, 1 case of biliary stone and 4 cases of tumors. Among 48 cases who were successfully treated, the levels of alanine aminotransferase, aspartate aminotransferase, γ-glutamyltransferase, alkaline phosphatase and total bilirubin at postoperative 48 h were all significantly lower than preoperative levels (all P<0.05). No severe complications occurred in 56 patients treated with SpyGlass system. Conclusions Use of SpyGlass system may significantly increase success rate and guarantee surgical safety in the treatment of complex biliary complications after liver transplantation, which is worthy of promotion and application.
RESUMO
Objective:To evaluate the clinical efficacy of PTCD and ERCP combined with T tube in the perioperative period of biliary anastomosis in patients with moderate to severe obstructive jaundice.Methods:The data of 93 patients with moderate obstructive jaundice who met the inclusion criteria and planned to undergo cholangiojejunostomy (including reconstruction after pancreaticoduodenectomy) in Shuguang Hospital Affiliated to Shanghai University of traditional Chinese medicine from March 2015 to December 2021 were collected. According to the perioperative drainage strategy, 54 cases were divided into PTCD group and 39 cases were divided into ERCP combined with intraoperative T-tube drainage group. Retrospective cohort method was used to analyze the bile duct diameter, postoperative hospital stay, operation cost, time of jaundice reduction, degree of jaundice reduction, average postoperative bile loss, postoperative bile leakage, abdominal infection of the two groups. The measurement data were expressed as mean ± standard deviation( ± s), and t test was used for comparison between groups. The data of skewed distribution were represented by M( Q1, Q3), and nonparametric rank sum test was used. Chi-square test was used for counting data. Results:The preoperative yellowing reduction time, operation cost, mean bile loss 7 days after operation, time to remove biliary drainage tube, and postoperative hospital stay in PTCD group were (5.9±3.1) d, (59 846.3±9 129.7) yuan, 210.0(170.0, 325.0) mL/d, (18.4±5.6) d, and(10.7±4.4) d, respectively, while those in ERCP group were (9.5±4.4) d, (77 833.1±12 164.5) yuan, 285.0(225.0, 370.0) mL/d, (41.4±17.2) d and(15.3±5.6) d, respectively. The difference between the two groups was statistically significant ( P<0.05). There was no significant difference between the two groups in general condition before drainage, cholangitis and hemorrhage after drainage, degree of jaundice reduction, bile leakage after surgery, abdominal infection, etc. Conclusions:When performing biliary enterostomy in patients with moderate or above obstructive jaundice, PTCD and ERCP combined with intraoperative T-tube drainage are effective means to improve the safety of perioperative period. PTCD has some advantages in reducing jaundice efficiency, operation cost and rapid postoperative rehabilitation.
RESUMO
Objective To discuss the clinical application of individualized strategy of endoscopic retrograde cholangiopancreatography (ERCP) in the treatment of bile duct stenosis after liver transplantation (LT).Methods Fifty-two patients,including 40 men and 12 women,aged 54.3 ± 9.1 years old,who suffered from bile duct stenosis and accepted 88 times of ERCP from June 2014 to May 2016 in our department were investigated.The procedures,clinical features and biochemical criteria were analyzed retrospectively.Results According to the treating occasions and clinical symptoms,single plastic stent,dilatation combined with single plastic stent,and dilatation combined with multiple plastic stents were chosen to use.ERCP in 8 patients out of 52 patients failed technically,and the therapeutic efficacy was 82.7％.The treatment duration was 8.2 ± 2.9 months.The recurrence rate was 4.7％ (2 cases) during the follow-up period.The most common complications were postERCP pancreatitis (2.3％) and cholangitis (3.4％),which would be cured by conservative treatment in most cases.Conclusion ERCP,as an effective and safe method,could be used as the first choice or bridge treatment for bile duct stricture after LT.We recommend individualization strategy,including step by step mode and different combinations of PTC or endoscopic procedures,in order to improve clinical efficacy of all kinds of stricture.
RESUMO
Objective To investigate the correlation between carotid intima-media thickness (CIMT) and glucose fluctuation in patients with type 2 diabetes mellitus (T2DM).Methods Sixty-eight T2DM patients admitted to Beijing Military General Hospital from March to August 2012 were enrolled in the study,including 32 cases with CIMT thickening (CIMT ≥ 0.9 mm) and 32 cases with normal CIMT (CIMT ＜0.9 mm).The 72 h continuous blood glucose levels were monitored from the day of admission.Results There were no significant differences in the gender,age,body mass index (BMI),systolic and diastolic blood pressure,HDL-C,LDL-C,CHO,TG,glycosylate hemoglobin (HbA1c),fasting blood glucose(FBG) and postprandial average blood glucose (MPBG) between two groups (P ＞ 0.05).The atherosclerosis (AS) score and mean amplitude of glycemic excursion (MAGE),glucose standard deviation,frequency of glycemic excursion (FGE) and absolute mean of daily differences (MODD) in patients with thickening CIMT were (11 ± 7) years,(6.9 ± 3.0) mmol/L,(2.8 ± 1.2) mmol/L,(3.4 ± 1.5) times/d,(2.8 ± 1.3) mmol/L,(4.5 ± 1.0) score,respectively ; while those in patients with normal CIMT were (8 ±6) years,(4.2 ± 1.1) mmol/L,(1.6 ± 0.5) mmol/L,(2.2 ± 0.8) times/d,(2.0 ± 1.0) mmol/L,(3.3 ±0.6) score,respectively.There were significant differences between two groups (all P ＜ 0.05).Pearson correlation showed that CIMT was positively correlated with MAGE,FGE,MODD,course of disease,diastolic blood pressure,LDL-C,MPBG and AS score (P ＜ 0.05).Multiple stepwise regression analysis showed that MAGE,MBPG were the influencing factors of CIMT.Conclusions The CIMT of patients with T2DM is closely correlated with glucose fluctuation,indicating that reduction of blood glucose fluctuation and MAGE,MPBG levels may delay the occurrence of diabetic macroangiopathy.
RESUMO
Pancreaticobiliary maljunction(PBM)is closely related to many surgical diseases in which are commonly seen in clinical practice.However,diagnosis of PBM is difficult and it is easily missed.The lack of knowledge and awareness of PMB has once made PBM “the forgotten corner of abdominal surgery”.This essay summarized the current knowledge on the diagnosis of PBM by medical imaging.
RESUMO
Objective To discuss the clinical significance of nephroscopic surgery for simple renal cysts. Methods A 2~4 cm incision was made below the 12th costal interspace. Through the incision the nephroscopic decortication was performed in 26 patients with simple renal cyst. Results The operation time was 20~80 min (mean, 30 min) and the postoperative hospital stay, 3~)6 days (mean, 4 days). No blood transfusion was required and no severe complications were noted. Follow-up observations for 3~)12 months (mean, 8 months) in the 26 patients found no recurrence. Conclusions Mini-incision nephroscopic decortication for renal cysts is feasible and mini-invasive, with advantages of simplicity of performance and quick postoperative recovery.
