Four hundred and eighty two paients suffering from intrahepatic bile duct stone undergoing lobectomy and segmental resection (from 1975 to 1994,9) has reported. 63% of the patient in this group underwent 1-5 operations, including different types of biliary-intestinal anastomosis (21.6%). 482 cases underwent different types of hepatectomy, including left lateral-lobetomy 321 cases (66.6%),left hemihepatectomy 80 cases(16.6%), right hemihepatectomy 19 cases (3.9%), and multiple segmental resections 39 cases (8.1%, including Ⅴ+Ⅷ 11 cases, Ⅵ+Ⅶ 28 cases). Other type hepatectomy combined with guadrate lobectomy 20 cases (4.1%). Postoperative complication rate was 10.2%, including diliary fistula. hemobilia and subdiaphragmatic and resectional surface infectioin, 85% of the patients were followed up with an excellent result of 88%. The authors emphsize that hepatic lobectomy nad segmental resection is the core of treatment and selection of operative methods depends on clinical-patholigic types of the disease.
ObjectiveTo investigate the clinical application effect of descending hilar plate technology in laparoscopic heminephrectomy for intrahepatic bile duct calculus.MethodsThe clinical data of 40 patients with intrahepatic bile duct calculus who underwent laparoscopic heminephrectomy in our hospital from January 2015 to December 2019 were retrospectively analyzed. The patients were grouped according to different surgical procedures, 21 patients with Pringle method of total hepatic vascular exclusion were classified in the control group, and 19 patients with descending hilar plate technology of blood occlusion technology were classified in the observation group. The operation time, intraoperative bleeding volume, postoperative hospital stays, liver function recovery, and postoperative complications were compared between the two groups.ResultsThere was no statistically significant difference between the two groups in the intraoperative bleeding volume and operation time (P>0.05), but the postoperative hospital stays in the observation group shortened (P=0.025). The changes on the ALT, TB, and AST in the observation group was obvious than those of the control group (P<0.05). There was no statistically significant incidence between the two groups in the total incidence of complications (P=0.128).ConclusionsCompared with Pringle method of total hepatic vascular exclusion, descending hilar plate technology in laparoscopic heminephrectomy can fully expose the Glisson pedicles of the left and right livers, and it is convenient to implement hemihepatic blood flow occlusion. It has less damage to healthy side of the liver and quicker liver function recovery, and it can reduce postoperative complications and shorten postoperative hospital stay.
【Abstract】ObjectiveTo investigate the anatomic feature and special clinical manifestations of variant right intrahepatic bile duct draining into left hepatic bile duct near the umbilical portion. MethodsVariant right intrahepatic bile ducts joining into left hepatic bile ducts near the umbilical portions were identified through cholangiograms in 52 patients, who were included in this study. Their history, clinical process and operations were reviewed. ResultsThere were total 38 cases of intrahepatic gallstone in this group. High incidence of intrahepatic calculi was found in variant right intrahepatic bile ducts （23/38 cases, 60.52%） and left hepatic ducts （33/38 cases, 86.84%）. Most of these cases were accompanied with dilatation and stricture of bile ducts in these area. The gallstones in the variant right intrahepatic bile ducts were not detected in 8 cases (8/23) and the rate of residual gallstone was as high as 86.95%(20/23). Injury of variant right intrahepatic bile duct took place when left hepatectomy was performed in one case. ConclusionGallstone is very likely to be formed in the variant right intrahepatic bile duct due to derangement of bile hydrokinetics and compression of blood vessel. Special attention should be paid to the diagnosis and operation of this abnormity.
ObjectiveTo investigate clinical efficacy and advantages and disadvantages of primary closure with two endoscopes (1aparoscope+choledochoscope) or three endoscopes (laparoscope+choledochoscope+duodenoscope) through the cystic duct for treatment of gallbladder stone with secondary common bile duct (CBD) stones.MethodsThe clinical data of 83 patients with gallbladder stones with secondary CBD stones treated by two or three endoscopes combined with CBD exploration and lithotomy and primary closure through cystic duct from January 2017 to December 2018 in the Chengdu Second People’s Hospital were collected retrospectively. Among them, 41 patients were treated by two endoscopes mode (two endoscopes group), 42 cases were treated by three endoscopes mode (three endoscopes group).ResultsThere were no significant differences in the general conditions such as the gender, age, preoperative diameter of CBD, chronic diseases, etc. between the two and three endoscopes group (P>0.05). All 83 cases underwent the operations successfully and recovered well. The success rate of operation, stone clearance rate, drainage volume of abdominal drainage tube on day 1 after the operation, time of abdominal drainage tube removal after the operation, and hospitalization time had no significant differences between these two groups (P>0.05). The time of operation, intraoperative bleeding volume, and the postoperative pancreatitis rate in the three endoscopes group were significantly more (or higher) than those in the two endoscopes group (P<0.05), but the condition of liver function recovered after the operation was better than that in the two endoscopes group (P<0.05).ConclusionsWith the strict control of the operation indications, it is safe and feasible to use two or three endoscopes through the cystic duct pathway and primary closure of CBD for treatment of gallbladder stone with secondary CBD stones. However, the choice of operative methods of two or three endoscopes should be based on the general situation of the patients before and during the operation.
Objective To investigate the recurrence of intrahepatic bile duct stones and study the relations to the primary intrahepatic stones.Methods One hundred and twenty nine patients who experienced complete lithotomy were followed up for 2-10 years. Results Thirty five cases had the recurrence of intrahepatic stones at 49 sites (27.13%). The recurrent stones were found at following sites: 13 at left duct, 12 right duct , 8 left medial segment, 6 right anterior segment, 4 right posterior segment, 3 left lateral segment, 3 caudate. Nine cases were asymptomic, 16 cases had slight symptoms and 10 cases suffered from the serious attacks of stones. The time of recurrence was from 2 to 9 years (5.49±2.25 years) after surgery. The recurrent rate was 27.13% in our group. Conclusion The recurrence of intrahepatic stones also developed at several sites in the liver. The recurrence of intrahepatic stones had a tendency to develop at the primary sites. The recurrence of intrahepatic stones may be asymptomic and most patients suffered from slight attack. Liver resection is the best way to prevent the recurrence from intrahepatic stones.
ObjectiveTo explore technical essentials and safety of laparoscopic cholecystectomy (LC) guided by gallbladder ampulla localization on an imaginary clock for cholecystitis.MethodsA retrospective study of 8 707 continuous patients with mild cholecystitis who underwent LC from July 1998 to February 2018 at a single institution was conducted. Among them, 3 168 patients were treated by the traditional LC from July 1998 to February 2007 (a traditional LC group), 5 539 patients were treated by the LC with the guidance of the gallbladder ampulla localization on an imaginary clock from March 2007 to February 2018 (a gallbladder ampulla localization group). The conversion to open surgery, bile duct injury, return to the operating room due to postoperative massive abdominal bleeding, bile leakage without bile duct injury, operative time, intraoperative blood loss, and postoperative hospital stays were compared between the traditional LC group and the gallbladder ampulla localization group.ResultsThere were no significant differences in the gender, age, course of disease, and type of cholecystitis between these two groups (P>0.050). The rates of conversion to open surgery, bile duct injury, return to the operating room due to postoperative massive abdominal bleeding, bile leakage without bile duct injury and the operative time, intraoperative blood loss and postoperative hospital stays in the traditional LC group were 3.00% (95/3 168), 0.13% (4/3 168), 0.09% (3/3 168), 0.03% (1/3 168), (43.6±12.6) min, (18.7±3.3) mL, (3.6±2.7) d, respectively, which in the gallbladder ampulla localization group were 0 (0/5 539), 0 (0/5 539), 0 (0/5 539), 0 (0/5 539), (32.2±10.5) min, (12.4±3.5) mL, (3.5±2.8) d, respectively. The differences of conversion to open surgery, bile duct injury, return to the operating room due to postoperative massive abdominal bleeding rates, and the operative time and intraoperative blood loss were statistically significant between these two groups (P<0.050). The differences of the bile leakage without bile duct injury rate and postoperative hospital stays were not statistically significant between the two groups (P>0.050).ConclusionThis study shows that gallbladder ampulla localization on an imaginary clock is useful for ductal identification so as to reduce bile duct injury and improve safety of LC in case of no conversion to open surgery.
ObjectiveTo investigate the clinical significances of intraoperative methylene blue diluent injection through the residual bile duct for bile leakage after hepatic hydatidosis surgery.MethodsThe patients with hepatic hydatidosis who received the surgical treatment in this hospital from December 2018 to November 2019 were randomly divided into a study group and control group. The patients in the study group received the treatment of anatomical or nonanatomical hepatic lobectomy. The first hepatic hilum was locked, then the methylene blue diluent was injected through the residual bile duct to find the bile leakage. The drainage tube was retained in the abdominal cavity after the surgery. The patients in the control group except the white gauze was used to compress the liver wound surface for 5 min to find the bile leakage, the other treatment process was the same as the study group. The operation time, intraoperative blood loss, liver function on day 3 after the surgery (total bilirubin, alanine aminotransferase, albumin), detection rate of bile leakage during operation, postoperative complications (pulmonary infection, ascites, incision infection, bile leakage, residual cavity infection, and electrolyte disturbance), postoperative hospitalization time, and total hospitalization cost were compared between two groups.ResultsAccording to the inclusion and exclusion criteria, 67 patients were included in this study, including 32 in the study group and 35 in the control group. There were no significant differences in the baseline data such as the age, gender, preoperative complications, preoperative liver function (total bilirubin, alanine aminotransferase, albumin), and liver hydatid classification between the two groups (P>0.05). The operations were successful in the 67 patients, no perioperative death occurred. The detection rate of bile leakage during operation in the study group was higher than that in the control group (53.1% versus 17.1%, P<0.05). The postoperative hospitalization time was shorter and the total hospitalization cost was lower in the study group as compared with the control group (P<0.05). There were no significant differences in the operation time, intraoperative blood loss, liver function on day 3 after the surgery between the two groups (P>0.05). There was no case of the incision infection, bile leakage, and residual cavity infection in the study group, but there were 1, 5 and 4 cases in the control group, respectively. The incidences of incision infection and bile leakage had statistical significances between the two groups (P<0.05), and there was no significant differences in the incidences of other complications between the two groups (P>0.05).ConclusionsDetection rate of bile leakage during operation is high by intraoperative methylene blue diluent injection through the residual bile duct for bile leakage after hepatic hydatidosis surgery. It could reduce bile leakage, shorten postoperative hospitalization time, and reduce total hospitalization cost.
To evaluate the effects of different pressure and duration of autologous bile perfusion into dog’s pancreatic duct on the severity of induced acute pancreatitis. Thirty mongrel dogs were divided into five groups, with each group consisting of six dogs. Histological changes of pancreas were observed. Results: Histological changes of pancreas were correlated with the pressure and duration of autologous bile perfusion into pancreatic duct. It was easier to produce acute hemorrhagic necrotizing pancreatitis in the groups with a higher pressure and a longer duration of perfusion than in the groups with a lower pressure and a shorter duration. The results indicated that there was a significant effect of higher pressure and longer duration bile perfusion into pancreatic duct on the severity of induced acute pancreatitis.
ObjectiveTo investigate the anesthesia management of transcatheter ultrasound-guided percutaneous interventional therapy for pediatric patients with congenital heart disease at a mobile surgical platform. Methods From March to July 2023, 13 patients in remote areas underwent interventional surgery on the mobile truck operating platform. The patients undergoing general anesthesia using non-tracheal intubation were collected. ResultsFinally, 8 patients received monitored anesthesia care (MAC) with local anesthesia-assisted sedation and analgesia drugs under the supervision of anesthesiologists (general anesthesia using non-tracheal intubation), due to the patients having difficulty cooperating with the surgery (young age, nervous mood, and crying), including 5 males and 3 females with an average age of 6.95±3.29 years and an average weight of 19.50±6.04 kg. There were 6 patients diagnosed with atrial septal defect, 1 patient with residual shunt after patent ductus arteriosus ligation, and 1 patient with severe pulmonary stenosis by transthoracic ultrasonography. The surgical process was smooth, analgesia was perfect, anesthesia and surgical effect were satisfactory, postoperative recovery was satisfactory, and there were no surgical or anesthesia complications. The anesthesia time was 41.53±8.62 min, the operation time was 39.88±8.52 min, and the recovery time was 41.50±14.56 min. Conclusion Transthoracic ultrasound-guided interventional surgery is a minimally invasive approach for congenital heart disease, offering the advantages of zero radiation exposure. Non-tracheal general anesthesia preserved spontaneous breathing can be safely and effectively administered to pediatric patients who cannot cooperate in mobile operating platform.
Objective To prevent bile duct injury, a new anatomy marker, named “common bile duct window” is created. Methods From November 2005 to March 2006, 60 patients who underwent laparoscopic cholecystectomy were researched in this hospital. All data were collected, including: age, gender, course of disease, body mass index (BMI), blood lipid level (triglyceride and cholesterol), the thickness of gallbladder wall and the degree of cholecystitis. The frequency, location and mean size of “common bile duct window” were recorded and calculated. Patients were divided into two groups according to the presence of “common bile duct window”, and the diference of data between two groups was analyzed by using χ2 test or t test. Results “Common bile duct window” was found at the end of hepatoduoduenal ligament with oval-shaped, the mean longitude of “common bile duct window” was (1.20±0.60) cm, and mean width was (0.45±0.30) cm. “Common bile duct window” were found in 81.6% (49/60) of patients. Age, gender, course of disease, BMI, triglyceride and cholesterol were proved to have no relationship with the presence of “common bile duct window” （Pgt;0.05）, but the thickness of gallbladder wall and the degree of cholecystitis affected the presence （P＜0.05）. Conclusion An oval-shaped “common bile duct window” can be found in almost all patients undergoing laparoscopic cholecystectomy. During the operation, the common bile duct can be located easily by the surgeon through “common bile duct window”, thereby to avoid common bile duct injury when the cyst duct was dissected. It is believed that during laparoscopic cholecystectomy the chances of bile duct injuries can be effectively decreased by the presence of “common bile duct window”.
