ABSTRACT
Objective To study the safety and efficacy of damage control using percutaneous transhepatic biliary drainage (PTBD) in acute cholangitis of severe type (ACST) secondary to intrahepatic choledocholithiasis.Methods The clinical data of 8 patients who received PTBD after hospital admission followed by conventional surgery for ACST when their general condition improved were retrospectively studied.Results All patients received PTBD successfully and the amount of bile drained was 100-400 ml in the first day.The general condition of these 8 patients became better after 24 h and the total bilirubin decreased for about 25-100 mmol/L after 48 h.Three patients with a platelet count of less than 20 × 109/L showed an improved count to more than 50 × 109/L 72 h after PTBD.All patients were operated at different times after the PTBD:2 received T-tube drainage,3 T-tube drainage combined with left hepatectomy,and 3 choledochojejunostomy.Seven patients recovered uneventfully,but 1 developed hepatic failure with the total billurubin rose to more than 200 μmol/L.He was discharged home with the PTBD tube.During the waiting time of 7 days to 3 months before surgery,the tubes were kept patent and no mortality or morbidity such as bleeding,bile leakage,and peritonitis occurred.Conclusions PTBD was a safe and efficacious procedure for patients who were in a serious condition with ACST secondary to intrahepatic choledocholithiasis.It was more likely to be successful as it is minimally invasive and therefore well-tolerented.It reduced the biliary pressure,relieved the ongoing sepsis,and was a good preparatory procedure before any conventional surgery.
ABSTRACT
Objective To determine if using a soft-tipped guidewire to cannulate the common bile duct may ameliorate development of PEP(post-ERCP pancreatitis)and facilitate cannulation of the CBD(common bile duct).Methods A total of 78 patients treated treateed in our hospital underwent ERCP through conventional direct cannulation(52 diagnostic ERCPs,26 therapeutics ERCPs)from 1998 to 2001 were randomly selected as group A while 112 patients underwent ERCP through guide wire-directed cannulation(21 diagnostic ERCPs,91 therapeutics ERCPs)from 2007 to 2008 as group B.Then we retrospectively studied and compared the following parameters between the two groups:1)Success rate of biliary access;2)visualization rate of pancreatic duct;3)the level of serum amylase,severity of abdominal pain and the rate of PEP.Meanwhile,the correlation between grading of pancreatic duct visualization and PEP was analyzed.Results The success rate of biliary access of the guidewire group(106/112 cases)was significantly greater than the conventional group(33/78 cases)(94.64%vs.42.30%,P<0.01).In group A,about61.53%(16/26)of the 26 cases could not continue the next therapeutics ERCP because of unsucceasful carmulation. The visualization rate of pancreatic duct of group A and B were 58.97%(46/78 cases)and 8.04%(9/112 cases)(P<0.01) respectively.On occurrence rate of PEP,group A(17/78 cases)was significantly higher than group B(4/112 cases)(21.79% vs.3.57%,P<0.01),and severe pancreatitis occurred in 3 patients in conventional group.However,there was no severe pancreatitis in the guide wire group.There were no significant differences (P>0.05) in terms of the rate of hyperamylasemia between the two groups.The significant correlation was found between the grading of pancreatic duct visualization and the occurrence of PEP.Condusion Guidewire-directed selective access to the bile duct lowers likdihood of PEP by facilitating cannulation and lowering the visualization rate of pancreatic duct.The occurrence of PEP could be predicted by the grading of pancreatic duct visualization,which is a very important but not the unique factor leading to PEP.
ABSTRACT
Objective To explore the clinical characteristics of portal vein thrombosis(PVT) after splenocaval shunt plus devascularization in treatment of portal hypertension and find Out ways for its prevention.Methods The formation,diagnosis,treatment of PVT and variceal rehemorrhage in 110 patients with portal hypertension who received splenocaval shunt plus devascularization procedures (Combined Group)and 92 patients subjected to pericardial devascularization operation(PCDV Group) were retrospectively analyzed.Meanwhile,the effect of two procedures on PVT was compared.Results The incidence of PVT was 10.0%in combined group and 22.8%in PCDV group (P<0.05).The rebleeding rate from esophagogastric varices because of PVT in combined group was 3.6%,which was significantly lower than that of 10.8%in PCDV group(P<0.05).Conclusion Splenoeaval shunt plus devascularization is a better choice to decrease the incidence of PVT.The postoperative anti-coagulation therapy in the early stage is important for the prevention of PVT.
ABSTRACT
Objective To investigate the clinical effects of a modified splenocaval shunt combined with pericardial devascularization ( PCDV ) in the treatment of gastroesophageal variceal bleeding. Methods From 1997 to 2007, 168 patients with gastroesophageal variceal bleeding caused by portal hypertension were treated at the People's Hospital of Shaanxi Province. Among all the patients, 90 received a splenocaval shunt + PCDV(combined group) and the remaining 78 received PCDV (PCDV group). Changes in intra- and postoperative hemodynamics of the portal venous system were detected by Doppler color flow imaging, and free portal pressure was measured intraoperatively. All data were analysed using analysis of variance, the paired t test and chi-square test.Results The mortality was 3% (3/90) in the combined group and 5% (4/78) in the PCDV group, with no significant difference between the two groups (x2 = 0.038, P ＞0.05 ). The postoperative rebleeding rate was 6%(5/79) in the combined group, which was significantly lower than 13% (8/60) in the PCDV group (x2 =4.824,P ＜ 0.05 ). The incidence of hepatic encephalopathy was 6% (5/79) in the combined group and 7% (4/60) in the PCDV group, with no significant difference between the two groups ( x2 = 0.072, P ＞ 0.05 ). The 1-, 3-, 5-,and 10-year survival rates were 97% (77/79), 92% (55/60), 80% (16/20) and 60% (3/5) in the combined group, and 97% (58/60), 83% (40/48), 73% (22/30) and 53% (8/15) in the PCDV group, respecitvely,with no significant difference between the two groups ( x2 = 0.731, P ＞ 0.05 ). The intra- and postoperative portal pressures in the combined group were (38.8±4.2) cm H20 ( 1 cm H2O =0. 098 kPa) and (33.1 ± 1.5) cm H2O,with a significant difference ( t = 8. 574, P ＜ 0.05 ). The intra-and postoperative portal pressures in the PCDV group were (38.9±2.5) cm H2O and (34.6±2.6) cm H2O, with a significant difference (t =6. 530, P ＜0.05 ). There was also a significant difference in postoperative portal pressure between the two groups ( t = 2. 859,P ＜ 0.05 ). The intra-and postoperative diameters of the portal vein in the combined group were (1.40 ± 0.41 )cm and ( 1.22 ± 0. 15) cm, respectively, with a significant difference ( t = 2. 608, P ＜ 0.05 ). The intra-and postoperative portal venous flows in the combined group were (1280 ±350) ml/min and (830±360) ml/min, with a significant difference ( t = 5. 668, P ＜ 0. 05 ). The intra-and postoperative diameters of the portal vein in the PCDV group were ( 1.41 ±0.32) cm and ( 1.27 ±0.32) cm, respectively, with no significant difference between the two groups (t = 1. 637, P ＞ 0.05 ). The intra-and postoperative portal venous flows in the combined group were ( 1350 ± 380) ml/min and (980 ± 290) ml/min, with a significant difference ( t = 4. 096, P ＜ 0.05 ). There was no significant difference in postoperative portal venous flow between the two groups ( t = 1.871, P ＞ 0.05 ).Conclusions The modified splenocaval shunt combined with PCDV is safe and effective with a low rate of recurrent rebleeding. The clinical outcome and rational hemodynamic changes show that the combined procedure of splenocaval shunt and PCDV is a good choice for treatment of gastroesophageal variceal bleeding.
ABSTRACT
Objective To investigate the short- and long-term complications after endoscopic Oddi's sphincterotomy (EST) upon endoscopic retrograde cholangiopancreatography (ERCP) procedure and determine whether the size of EST correlates to the occurrence of EST complications.Methods 95 cases receiving EST in the process of ERCP in our hospital were studied and followed up. The patients were divided into large, moderate and small incision groups according to the size of EST and the states of short-term and long-term EST complications were statistically analyzed.Results The incidence of short-term complications of EST was 18. 94% (18/95). They included bleeding in the process of ERCP in 11 cases, delayed bleeding in 3, acute pancreatitis in 1, acute cholangitis in 2 and duodenal perforation in 1. All these patients but 1 with duodenal perforation were discharged after undergoing symptomatic treatments. Eleven out of the 95 patients had long-term complications (11.57 % ). These included biliary system infection in 5 cases, recurrent calculus of bile duct in 3, papilla stricture in 1 and chronic relapsing pancreatitis in 2. All 11 patients recovered after therapeutic ERCP again or symptomatic drug treatments. There was no significant difference in incidence of short-term (χ2 =2.433, P=0.296) or long-term complications (χ2 = 1.151, P=0.562) among the 3 groups. Furthermore, there was no statistical correlation between the incision size of Oddi and complications including operative bleeding (P=0.109), short-term complications (P=0.124) and longterm complications(P=0.402). Conclusion There are many short-term and long-term complications after EST, but there is no correlation between the complications and the incision size of Oddi. The occurring rate of complications might be reduced through accurate direction of papilla incision, avoidance from injury of blood vessel, keeping bile drainage unobstructed and protection of the function of Oddi sphincter as far as possible in the process of ERCP.
ABSTRACT
Objective To evaluate the effects,hemodynamies and hepatic functional reserve of a combined procedure of modified pmximal splenocaval shunt and pericardial devascularlzation (PCDV) in the treatment of portal hypertension.Methods From 1997 to 2007,a total of 255 patients with cirrhotic portal hypertension received combined (135 cases) or PCDV procedure (120 cases,) in our hospital.The clinical results were retrospectively analyzed.Changes of hemodynamics of the portal venous system were studied by Doppler color flow imaging and intraoperative free portal pressure (FPP) measurement.The hepatic functional reserve was evaluated by indocyanine green (ICG) retention ratio and functional hepatic flow(FHF).Results Postoperative mortality was 2.2% in combined group and 4.3% in PCDV group.The long term rebleeding rate was 5.5%as revealed by follow-up in combined group,which was significantly lower than that in PCDV group of 14.1%(P<0.05).The incidence of encephalopathy was 6.4%and 5.4%in combined group and PCDV group respectively(P>0.05).The 1-,3-,5-and 10 year-survival rates were 96.4%,90.0%,81.3%and 62.5% in combined group and 95.7%,86.7%,75.0%,57.1%in PCDV group.In combined group,the FPP、PVF and FHFwere(32.0±1.5)cm H_2O、(880±260)ml/min and(430±1 80)ml/min respectively,a significant decrease when compared with preoperative parameters (P<0.05),while R_(15) (30%±4%)increased (P<0.01).The similar results were observed in PCDV group postoperatively (P<0.05).Compared to PCDV group,the decrease of FPP in combined group was more significant(P<0.05),but the PVF,FHF and R_(15) were not significantly different (P>0.05).Conclusions The combined procedure is safe and effective in treatment of portal hypertension with better clinical outcome,moderate homodynamic changes and good maintenance of hepatic functional reserve.
