Objective To explore primary surgical treatment experience of typeⅣ hilar cholangiocarcinoma. Methods From April 2008 to April 2011，20 patients with type Ⅳ hilar cholangiocarcinoma were enrolled into the same surgical group in Department of Hepatobiliary and Pancreatic Surgery of West China Hospital of Sichuan University.The intra- and post-operative results were analyzed.Results The total resection rate was 75%，which was consisted of 10 cases of radical excision and 5 cases of non-radical excision.Seven patients received left hepatic trisegmentectomy and caudate lobe resection including anterior and posterior right hepatic duct reconstruction，hepatojejunostomy，and Roux-en-Y jejunojejunostomy.Six patients received enlarged left hepatic trisegmentectomy and caudate lobe resection including left intrahepatic and extrahepatic duct reconstruction，hepatojejunostomy，and Roux-en-Y jejunojejunostomy. Two patients received quadrate lobe resection including two cholangioenterostomies after anterior and posterior right hepatic duct reconstruction，and left intrahepatic and extrahepatic duct reconstruction.After percutaneous transhepatic cholangial drainage （PTCD） and portal vein embolization （PVE），two patients with total bilirubins ＞400 mmol/L received radical excision and non-radical excision，respectively.Three patients only received PTCD during operation due to wide liver and distant metastasis，and two patients received T tube drainage during operation and postoperative PTCD due to left and right portal vein involvement. All 15 patients who received lesion resection survived more than one year， whereas another five patients whose lesions can not been resec ted only survived from 3 to 6 months with the mean of 4.2 months.No death occurred during the perioperative period. Conclusions For patients with type Ⅳ hilar cholangiocarcinoma， preoperative evaluation and tumor resection shall conducted so as to relieve obstruction of biliary tract，otherwise PTCD and PVE prior to the final lesion resection shall be performed.
ObjectiveTo study the effectiveness of liver function, hepatic energy metabolism, regeneration, and apoptosis on the obstructive jaundice rat after partial hepatectomy (PH) combined with internal biliary drainage under the condition of conspicuous bilirubinemia. MethodsOne hundred and twenty male SD rats were used in research, six of whom were divided into sham operation (SO) group. Twenty rats underwent bridge operation between common bile duct and duodenum after 70% PH (70%PH group), and 6 rats out of the 94 rats who underwent common bile duct ligation (CBDL) for 5 d were randomly selected as CBDL group, and the residual rats were done the second operations after 5 d and were divided into three groups: bile duct obstruction combined with reperfusion of bile flow group （BDO-RBF group， n=20), 42% PH with BDO-RBF group (n=20), and 70%PH with BDO-RBF group (n=25). Levels of TB, ALT, ALB, and ALP in serum; HGF, bcl-2 mRNA and protein； ATP, ADP, and AMP; hepatocyte proliferation/apoptosis index in hepatic tissues were dynamically observed after operation (24 h, 72 h, and 7 d), respectively. The liver function and hepatocyte energy metabolism were only detected in the SO group. ResultsRats without obstructive jaundice would have an excellent liver regeneration after 70% PH, while the liver function and hepatocyte energy metabolism could recover rapidly. The liver function, hepatocyte energy metabolism, HGF and bcl-2 mRNA and protein of liver tissue and the hepatocyte proliferation/apoptosis index in partial (42% or 70%) hepatectomy combined with internal biliary drainage in obstructive jaundice group were significantly influenced while recovered rapidly (Plt;0.05). ConclusionsUnder the condition of conspicuous bilirubinemia, the influences of hepatectomy combined with internal biliary drainage on hepatocyte energy metabolism, liver function, hepatocyte regeneration and apoptosis are severer than that of normal rats who underwent 70% hepatectomy, while also make the rats recover rapidly in hyperbilirubinemia groups. The database suggest that it is not necessary to do preoperative external biliary drainage before performing liver resection.
Objective To investigate the safety and effectiveness of the operation of integrate subparagraph, fenestration, exclusion, cut expansion, seton, tube, and drainage (ISFECSTD) to cure complex anal fistula. Methods Using randomized comparison and multicenter parallel experiment, the total number was 240: 120 patients in study group treated by ISFECSTD, and 120 patients in control group treated by extended cutting and seton operation. Then compared the safety and effectiveness between two groups. Results The clinical recovery rate of the study group was significantly higher than that in the control group （Plt;0.05）. The operation time and wound healing time in study group were significantly less than those in control group, and the scar area after wound healing was smaller than that in control group （Plt;0.01）. The decreased extents of anorectal pressures and rectal capacity feeling function after operation in study group were smaller than those in control group (Plt;0.01). Rectal and anal reflex function and healing of the endostoma, stem, and branch in study group were better than those in control group (Plt;0.05, Plt;0.01). Incidence of anal incontinence after operation in study group was significantly less than that in of anus-rectum structure and function, and has the merits of higher cure rate, shorter time of healing, smaller scar, less pain, etc. The method of ISFECSTD is worth being a new standardized operation in the clinical application.
ObjectiveTo investigate the effect of drained versus nondrained pancreaticojejunostomy on prevention of the pancreatic leakage after pancreaticoduodenectomy. MethodsSeventysix patients underwent the standard pancreaticoduodenectomy including resection of the distal stomach,common bile duct, the head of pancreas and the duodenum.Pancreaticenteric reconstruction was accomplished via either pancreaticojejunostomy by endtoside anastomsis or pancreaticojejunostomy by ducttomucosa anastomsis.The stented external drainage of pancreatic duct was used in 45 of 76 patients. ResultsPancreatic leakage was identified in 1 patient in the drained group consisting of 45 patients,in 7 patients in the nondrained group consisting of 31 patients, the incidence of pancreatic leakage in the drained group (2.2%) was significantly less than in the nondrained group (22.6%,P＜0.05).ConclusionComparing the incidences of pancreatic leakage from both groups,the authors believe that the stented external drainage of pancreatic duct can significantly reduce the incidence of pancreatic leakage after pancreaticoduodenectomy.
Rupture is one of main complications of liver abscess. Seventy-seven patients with rupture of liver abscess are reviewed. Liver abscess may freely rupture into adjacent structures or organs or serous cavities and cause vatious complications. The causative factors of rupture of liver abscess in this series were late medical consultation in the course of the disease, delayed treatment due to misdiagnosis, and improper treatment. Measures that prevent rupture of liver abscess include raising clinical awareness of early diagnosis and timely effective drainage. The authors consider that transperitoneal surgical drainage is the best approach. Most patients with rupture of liver abscess should be treated by surgical drainage togather with transomental or transumbilital veno-catheterization for antibiotic infusion. Patients with rupture of liver abscess usually present a poor prognosis and a high mortality rate. The mortality in this group was 35.1%(27/77), which is closely related to the complications of the rupture of liver abscess.
The comparison made between two experimental models with obstructive jaundice, which were newly established reversible model and traditional bile duct ligation and internal drainage model, showed that the new model was superior to the traditional one. This study suggests that the new model would be an ideal model, which could replace the traditional one for studying obstructive jaundice.
One hundred and five hepatic resection were performed from 1984 to 1994. Six of these patients complicated with subphrenic infection after hepatectomy, of whom two patients died of liver failure. Subphrenic dropsy occureeed in nine cases. Subphrenic infection is easy to occur in: right or extend lobectomy, massive blood loss at operation, and in postoperative bleeding which subjects to laparotomy for lemostasis. Seecure hemostasis, avoidence of hepatic tissue devitalization during operation and effective subphenic drainage aree essential to reduce the incidencee of subphrenic infection, and routine bacterial culture of subphrenic drainage fluid will help to select propre antibiotic.
Objective To explore the effectiveness and safety of self-made washable endotracheal tube for subglottic secretion drainage. Methods Ordinary endotracheal tube and sputum aspirating tubes were used to make washable endotracheal tube for subglottic secretion drainage in our hospital. The self-made tubes were compared with washable endotracheal tube available on the market. The suction resistance, the cases of obstruction in the tubes, the average daily drainage, and the cases of infection of incisional wound were compared between the two kinds of tubes, and their safety was evaluated. Results After three days of application, the suction resistance of endotracheal tube available on the market increased, with six cases of the blockage of the lumen ( 85% ) , while that of self-made endotracheal tube did not change, with no cases of blockage ( 0% ) . There was significant difference between these two kinds of tubes ( P lt;0. 01) . The average daily drainage in the former was ( 16. 55 ±8. 66) mL/d; while that in the latter was ( 40. 12 ±25. 48) mL/d. There was no significant statistical difference between the two kinds of tubes ( P gt;0. 05) . The incidence ofinfection of incisional wound in the ordinary endotracheal tube was 50% ( 5 cases) ; that in the tubes available on the market was 28% ( 2 cases) ; that in the self-made tubes was 15% ( 2 cases) . There was significant difference among the three groups. When tube cuffs were inflated, the distance between the back edge of suction tubes and tube cuffs was was 2-4 mm. Conclusion Self-made washable endotracheal tubes are effective for subglottic secretion drainage with good safety and low price.
Proper management of chest drainage after pulmonary lobectomy is a topic that every thoracic surgeon must face up to. Reasonable chest drainage plays a critical role in postoperative normal physiological recovery. However， there are still controversies and discrepancies in many aspects of chest drainage management after pulmonary lobectomy. In this review，we focus on five aspects of chest drainage management after pulmonary lobectomy，including the choice of chest drainage system，single or double chest tubes，suction or not，treatment of persistent air leak，and removal of chest tube.
Abstract： Objective To summarize early clinical result of total cavopulmonary connection, and analyze the risk factors contributing to prolonged postoperative recovery. Methods Between February 2009 and August 2010, 58 patients with functional univentricular complex congenital heart disease received total cavopulmonary connection in Beijing Fu Wai Hospital. All of them were diagnosed by echocardiogram and angiography including 26 patients with single ventricle, 10 patients with tricuspid atresia, 4 patients with pulmonary artery atresia, 5 patients with double outlet rightventricle, 1 patient with transposition of great arteries, and 12 patients with corrected transposition of the great arteries.Fifty seven patients underwent extracardiac conduit total cavopulmonary connection, and only one patient underwent total cavopulmonary connection with an intracardiac lateral tunnel. According to their postoperative pleural drainage volume and duration, these 58 patients were divided into a large pleural drainage volume group (17 patients with 10 males and 7 females, mean age of 8.61±6.73 years）that included patients with large volume and long duration of pleural drainage, and a little pleural drainage volume group (41 patients with 15 males and 26 females, mean age of 7.21±4.24 years) . A univariable analysis was conducted to compare the risk factors that effected recovery result between the two groups. Results There was no death in hospital period. The average length of hospital stay was 12.30±9.80 d . Average drainage time (18.00±5.50 d versus 5.00±2.20 d , t= -1.967, P ＜ 0.05）, drainage volume (12.30±2.60 ml/(kg·d) versus 2.80±1.70 ml/(kg·d), t=-3.221, P ＜ 0.05), and hospital stay (20.10±7.20 d versus 7.20±1.10 d, t=-2.003, P ＜ 0.05） of the large pleural drainage volume group were significantly larger or longer than those of the little pleural drainage volume group. Univariate analysis showed that preoperative pulmonary pressure measured by catheter in the large pleural drainage volume group was significantly higher than that in the little pleural drainage volume group (17.42±5.34 mm Hg versus 13.91±5.22 mm Hg，t=-2.073，P ＜ 0.05). Conclusions The mortality and major morbidities after total cavopulmonary connection are low in the current era. Preoperative high pulmonary pressure is a risk factor for large amount of pleural drainage and prolonged recovery.
