Forty nine patients were recoverwd from the teatment and 1 patient died.
Objective To explore the diameter change of the extrahepatic bile duct before and after laparoscopic cholecystectomy (LC). Methods From Jan. 2006 to Dec. 2007， 113 patients including chronic gallstone cholecystitis （n=55）, inactive cholecystolithiasis （n=46） and gallbladder polyps （n=12） were collected and treated by LC. The diameters of their extrahepatic bile ducts were measured by B ultrasonography before operation， 3 months and 6 months after operation. These data were collected and analyzed retrospectively. Results The diameters of the extrahepatic bile ducts of all patients before LC， 3 months and 6 months after LC were (5±2) mm, (8±2) mm and (6±2) mm respectively. And in chronic gallstone cholecystitis patients they were (5±2) mm, (9±2) mm and (6±2) mm respectively， in inactive gallstone cholelithiasis patients they were (5±2) mm, (8±2) mm and (6±2) mm respectively， and in gallbladder polyps ones they were (5±2) mm, (7±2) mm and (5±2) mm respectively. Conclusion The change of the extrahepatic bile duct diameter after LC is a dynamic process. It is enlarged on the third month after operation than before operation. In the sixth month after operation marked retraction occurs, and compared with before operation, it shows no obvious statistic significance.

Methods : One hundred and five serum samples from patients with liver cirrhosis were detected in PAB, ChE, TBA and other biochemical markers. All patients were classified in accordance with ChildPugh scale. Results : For PAB, the differences among ChildPugh A, B, C and healthy group were statistically significant (t=1254, 1887, 2316) (Plt;001). For ChE, the differences among ChildPugh A, B, C and healthy group were statistically significant (t=1288, 0856, 1002) (Plt;001). For TBA, the differences among ChildPugh C group, B group and A group were statistically significant (t=0526, 1081)(Plt;001), the difference among ChildPugh A group and healthy group was not statistically significant (t=5615) (Pgt;005). Conclusion : PAB and ChE reflect liver reserve function earlier in patients with liver cirrhosis. The role of TBA is important in reflecting prognosis in patients with liver cirrhosis.
As an important tool for nucleic acid detection of variant strains of severe acute respiratory syndrome coronavirus 2 (SARS CoV-2), the mobile air capsule construction laboratory is a key medical resource in the prevention and control of COVID-19. Medical staff, security guards, cleaners, maintenance workers and volunteers in the mobile air capsule construction laboratory have high contact frequency with the samples, so they have a high risk of infection with COVID-19. In order to reduce this risk, this article discusses the infection management measures in the aspects of wearing and taking off personal protective equipment, environmental health management, post use goods management, medical waste management, staff training management and disposal process after occupational exposure, and analyzed the common problems in operation, based on the operation process of Nanchong mobile air capsule construction laboratory. The purpose is to provide a reference for the construction and management of other mobile air capsule construction laboratory.
【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.
Objective To compare the difference of anterior knee pain between mobile-bearing prosthesis and fixedbearing prosthesis after total knee arthroplasty (TKA). Methods Between January 2008 and October 2008, 72 patients withosteoarthritis were treated with primary TKA. All patients were randomly divided into fixed-bearing prosthesis group (n=37)and mobile-bearing prosthesis group (n=35). In fixed-bearing prosthesis group, there were 8 males and 29 females with an average age of 69.6 years (range, 57-76 years), weighing from 55 to 92 kg (mean, 66.7 kg); the locations were the left knee in 20 cases and the right knee in 17 cases; the body mass index (BMI) ranged from 17.6 to 37.3 (mean, 26.2); the disease duration was 3-22 years; the Knee Society Score (KSS) knee score, function score, patellar score, and pain score were 29.4 ± 15.3, 33.4 ± 16.8, 7.2 ± 2.5, and 2.5 ± 2.2, respectively; and the Insall-Salvati (I-S) index was 1.6 ± 0.3. In mobile-bearing prosthesis group, there were 9 males and 26 females with an average age of 68.2 years (range, 58-73 years), weighing from 50 to 86 kg (mean, 67.9 kg); the locations were the left knee in 30 cases and the right knee in 5 cases; the BMI ranged from 18.4 to 34.4 (mean, 25.6); the disease duration was 6-18 years; the KSS knee score, function score, patellar score, and pain score were 30.9 ± 14.7, 31.4 ± 14.4, 6.8 ± 3.1, and 2.0 ± 2.3, respectively; and the I-S index was 1.6 ± 0.2. There was no significant difference in general data between 2 groups (P gt; 0.05). Results All incisions healed by first intention; no deep vein thrombosis of lower l imbs or pulmonary embol ism occurred. All patients were followed up 12-16 months. In mobile-bearing prosthesis group, knee infection occurred in 1 case, dislocation of the knee in 1 case, and cl icking of the knee in 3 cases; in fixed-bearing prosthesis group, cl icking of the knee occurred in 1 case. There was no significant difference in KSS knee score, function score, patellar score, or pain score between 2 groups (P lt; 0.05) at last follow-up; and there was no significant difference in congruence angle, lateral patellofemoralangle, patellar tilt angle, lateral patellar displacement, patellar displacement, or I-S index between 2 groups at last follow-up (P gt; 0.05). Anterior knee pain occurred in 7 cases (18.9%) of the fixed-bearing prosthesis group and in 5 cases (14.3%) of the mobilebearing prosthesis group, showing no significant difference (χ2=0.227, P =0.634). There were significant differences in KSS knee score, function score, patellar score, and I-S index between patients with anterior knee pain and patients without anterior knee pain (P lt; 0.05). Conclusion Fixed-bearing prosthesis and mobile-bearing prosthesis have the same short-term effectiveness and the incidence of anterior knee pain.
ObjectiveTo observe the effects of oral Xiaoyan Lidan tablets(XYLDT) on the bile composition(total bile acids, cholesterol, phospholipids) in patients with intrahepatic duct stones after common bile duct exploration(CBDE) with T tube drainage, to explore its possible preventive effects on stone recurrence. MethodsForty consecutive patients with intrahepatic bile duct stones who underwent CBDE with T tube drainage were randomly divided into experi mental group and control group. XYLDT were administrated at day 4 after surgery in experimental group(n=20), while none of medication were given in control group(n=20). 2 mL of bile was collected through T tube in both groups at day 1, 2, 3, 7, 14, and 21 postoperatively. Total bile acids(TBA), cholesterol(CHO), and phospholipids(PLIP) in bile were measured, and TBA/CHO ratio and PLIP/CHO ratio were calculated respectively. The results were statistical analyzed. ResultsThe demographic data in both groups including age, gender, height, weight, preoperative concomitant diseases, operative time, postoperative complications, hospital stays, serum total bilirubin, direct bilirubin, alanine aminotransferase(ALT), aspartate aminotransferase(AST), and amylase were not significantly different(P > 0.05). The measurements of TBA, CHO, PLIP, and the ratio of TBA/CHO and PLIP/CHO in bile were not significant on day 1, 2, and 3 after surgery in both groups(P > 0.05). In experimental group, the TBA, CHO, and PLIP on day 7, 14, and 21 after surgery were significantly increased compared with the control group(P < 0.05). The ratio of TBA/CHO on day 7, 14, and 21 was 2.17±0.29, 2.29±0.44, and 2.59±0.58, the ratio of PLIP/CHO was 2.03±0.68, 2.84±0.64, and 2.86±0.77, respectively, which were also significantly increased compared with the control group(P < 0.05). ConclusionsOral XYLDT can increase the secretion of TBA, CHO, and PLIP, elevate the TBA/CHO and PLIP/CHO ratio, and change the bile composition which may increase the dissolution of cholesterol in the bile. Presumably, oral XYLDT may have preventive effects in the recurrence of intrahepatic bile duct stones.
Objective To explore the clinical therapeutic value of pancreatoduodenectomy in patients with carcinoma of ampulla of Vater (AVC). Methods The clinical data of 195 patients with AVC between March 1995 and March 2009 in this hospital were analyzed retrospectively. All the patients were divided into non-surgery group (n＝51), palliative surgery group (n＝96), and resection group (n＝48) according to the treatment methods. Results The 1-year, 3-year, and 5-year survival rates in the resection group were higher than those in the non-surgery group and the palliative surgery group (Plt;0.01). However, the incidence of complications in the resection group was higher than that in the nonsurgery group or the palliative surgery group (Plt;0.05). The radical resection rates, 1-year, 3-year, and 5-year survival rates of carcinomas of head of pancreas were significantly lower than those of carcinomas of the terminal of common bile duct or carcinomas of duodenal papilla (Plt;0.05, Plt;0.01). There was no significant difference of the perioperative mortality, complications rate, 1-year, 3-year, or 5-year survival rate between preoperative drainage jaundice group and preoperative nondrainage jaundice group (Pgt;0.05). The perioperative mortality in the resection group above the age of 70 years old was higher than that of less than or equal to 70 years old （Plt;0.05）. Compared with the non-surgery group or palliative surgery group, there were significant increasement of the incidence of serious or deadly perioperative complications in the resection group (Plt;0.05). Conclusions Surgical resection remains one of the most important measures of the treatment of AVC, in particular, the radical pancreatoduodenectomy is the only effect way for AVC, thus significantly prolonging the patient’s postoperative survivals and significantly improving the qualities of life.

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.
