目的对单层吻合在消化道手术中临床应用的安全性和实用性进行评价。方法对该院1 600例消化道单层吻合术的临床资料进行回顾性分析，并结合国内外文献进行讨论。结果全组1 600例消化道单层吻合手术均顺利完成，发生吻合口漏25例（1.56%），吻合口狭窄3例（0.19%），无一例发生吻合口大出血。结论消化道单层吻合不会增加吻合口漏的发生率，并能减少吻合口狭窄、梗阻和出血，是安全、实用且有效的吻合方法。

Objective To determine the clinical efficacy of probucol in patients with diabetic macular edema (DME) and elevated serum lipids after focal/grid laser photocoagulation. Methods A prospective randomized controlled study included 48 type 2 diabetic patients with DME and dyslipidemia which were randomly divided into three groups. For patients with bilateral disease only the more severe eye was included. All patients were subjected to strict metabolic and blood pressure control during enrollment. All cases received macular laser photocoagulation. Besides, sixteen patients in group A were treated with probucol, 16 members in group B with atorvastatin and 16 members in group C were not treated with any lipid-lowering therapy for about three months. The outcome measurements were status of macular edema and hard exudates, visual acuity, foveal thickness, serum lipids and urine 8-hydroxydeoxyguanosine (8-OHdG) during the three months. Results The study included 20 men and 28 women with noninsulin dependent diabetes mellitus who could achieve good metabolic and blood pressure control within three months of inclusion in the study. Thirteen of 16 patients in group A, twelve of 16 patients in group B and five of 16 patients in group C showed reduction in hard exudates. Regression of macular edema was seen in twelve patients in group A, 11 in group B and eight in group C (χ2=2.368,P＞0.05). The difference of foveal thickness in group A, B and C was statistically significant (t=4.929, 4.669; P=0.000). Nine patients in group A, eight in group B and six in group C showed improving of visual acuity (χ2=1.169,P＞0.05). Three months after treatment, triglycerides (TG) (t=7.954, 6.832; P＜0.05), total cholesterol (TC) (t=6.643, 5.368; P＜0.05) and low-density lipoprotein cholesterol (LDLC) (t=3.279, 3.835; P＜0.05) decreased in group A and group B but not in group C, and high-density lipoprotein cholesterol showed no significant difference in the three groups. 8-OHdG decreased gradually during the first and third month in group A and group B but not in group C. In the first month post treatment, 8-OHdG showed no difference between group A and group B. In the third month, the 8-OHdG was lower in group A than group B, and the difference was statistically significant (t=2.947,P＜0.05). ConclusionsIn type 2 diabetes patients with DME and dyslipidemia, oral probucol can reduce the severity of hard exudates and macular edema, improve the visual acuity, and inhibit the levels of TG, TC, LDLC and 5-OHdG. The effect of probucol was similar to atorvastatin. Probucol could be an adjunct treatment of those patients.
Objective To explore the indications for liver transplantation among patients with hepatolithiasis. Methods Data from 1431 consecutive patients with hepatolithiasis who underwent surgical treatment from January 2000 to December 2006 were retrospectively collected for analysis. Surgical procedures included T-tube insertion combined with intraoperative cholangioscopic removal of intrahepatic stones, hepatectomy, cholangiojejunostomy, and liver transplantation. Results Nine hundred and sixty-one patients who had a stone located in the left or right intrahepatic duct underwent hepatectomy or T-tube insertion combined with intraoperative cholangioscopic removal of intrahepatic stones. The rate of residual stones was 7.5% (72/961). Four hundred and seventy patients who had a stone located in the bilateral intrahepatic ducts underwent surgical procedures other than liver transplantation; the rate of residual stones was 21.7% (102/470). Only 15 patients with hepatolithiasis underwent liver transplantation; they all survived. According to the degree of biliary cirrhosis, recipients were divided into 2 groups: a group with biliary decompensated cirrhosis (n=7), or group with biliary compensated cirrhosis or noncirrhosis group (n=8). There were significant differences in operative times, transfusion volumes and blood losses between 2 groups (P＜0.05). In the first group, 6 of 7 patients experienced surgical complications, and in the second, 8 recipients recovered smoothly with no complications. Health status, disability and psychological wellness of all recipients (n=15) were significantly improved in 1 year after transplantation as compared with pretransplantation (P＜0.05). Conclusion Liver transplantation is a possible method to address hepatolithiasis and secondary decompensated biliary cirrhosis or difficult to remove, diffusely distributed intrahepatic duct stones unavailable by hepatectomy, cholangiojejunostomy, and choledochoscopy.
肝内、外胆管结石是常见病，治疗以外科手术为主。传统开放手术治疗疾病的同时，对患者创伤亦大。随着腹腔镜、胆道镜以及十二指肠镜技术的日益成熟，许多原本需要开腹处理的肝内、外胆管结石可用微创手术治疗，现就腹腔镜联合治疗肝内、外胆管结石的几种手术方式及其常见并发症探讨如下。1 腹腔镜胆总管探查术(laparoscopic common bile duct exploration)腹腔镜胆囊切除术(LC)初期，胆囊结石并胆总管结石一般选择分期处理，即采用LC前或后行内镜括约肌切开取石术(EST)的办法，这种分期手术避免了开腹胆总管探查，但其缺点也显而易见： 据文献\[1\]报道，即便对有经验的内镜医师而言，EST仍有5%～19%的并发症发生率和1.3%的死亡率，而且EST的应用显著增加了患者的费用; 对年轻患者尚需长期随诊观察EST后乳头括约肌的功能状况。腹腔镜胆总管探查术为处理胆囊结石并胆总管结石提供了新的选择。目前多数学者认为,EST除明确应用于术后发现胆总管结石的病例外，术前及术中发现的胆总管结石病例以行腹腔镜胆总管探查术为宜\[2\]。腹腔镜胆总管探查术有两种途径: 经胆囊管或胆总管切开探查取石，后者又根据T管放置与否分为T管引流术和一期缝合术。.......
Fifty three patients with acute necrotizing pancreatitis were performed operation, treated surgically, including incision of the pancreatic capsule to release the pancreatic presure, removal of necrotic tissue, and placement of drainage tube around pancreas. Twenty two patients (41.5%) developed postoperative peripancreatic abscess. The average hospitalized days (83.3±25.1 days) of the patients with peripancreatic abscess was longer than those without (22.7±14.7 days) peripancreatic abscess (Ｐ＜0.01). Six cases of 28 (21.4%) patients who had localized or scattered pancreatic necrosis developed peripancreatic abscess, 16 cases of 25 (64.0%) patients who had subtotal or total pancreatic necrosis developed peripancreatic abscess which showed significant difference between two groups (Ｐ＜0.01). Among 21 patients in whom 2 to 4 doublelumened tubes for negative presure drainage were placed,5 cases (23.8%) had peripancreatic abscess but 32 patients with only one tube placed, 17 patients (53.1%) had peripancreatic abscess, the difference between two groups were significant (Ｐ＜0.05). At least 6 patients whose drainage tubes worked badly produced postoperative peripancreatic abscess. These results indicate that the peripancreatic abscess is closely related with the severity of the disease, surgical treatment, and proper postoperative care of the drainage tubes.
