目的:比较腹腔镜辅助胆道镜微创保胆取石术(LR C L)与腹腔镜胆囊切除术(LC)治疗胆囊结石的临床疗效。方法:将105例胆囊结石患者随机分为LR C L组45例和LC组60例,比较两组手术时间、术中出血量、术后肠蠕动恢复时间、术后饮食恢复时间、住院时间、住院费用及术后并发症情况。结果:术中出血量LR C L组少于LC组。术后饮食恢复时间、术后并发症发生率LR C L组明显优于LC组(P0.05)。在手术时间、术后肠蠕动恢复时间、住院时间、住院费用上,LR C L组与LC组差异无统计学意义(P0.05)。LR C L组术后半年、1年的胆囊收缩功能和胆囊壁厚度比术前有较大改善,差异有统计学意义(P0.05)。LR C L组术后1年复查结石复发率2.22%,术后2年复查结石复发率4.44%,术后3年复查结石复发率6.67%。结论:腹腔镜辅助胆道镜保胆取石术治疗胆囊结石安全有效,能够保留有功能的胆囊,提高患者的生存质量。 相似文献

Background/Purpose. Gallstone ileus is an uncommon complication of cholelithiasis in the elderly with a high morbidity and mortality rate. This study aims to clarify the current surgical management.
Methods/results. In a retrospective survey over the past 11 years there were 9 patients with gallstone ileus, all elderly (mean age, 77 years), among 2242 cholecystectomies (0.4%) and 243 operated small intestinal obstructions (3.7%). Urgent laparotomy confirmed gallstone obstruction and a cholecystoduodenal (89%) or cholecystocolonic (11%) fistula. The operation included enterolithotomy alone (3 high-risk cases) or plus fistula repair and cholecystectomy (6 cases). There were 3 postoperative complications including wound dehiscence, wound infection, and obstructive jaundice (morbidity, 37.5%) and 1 death due to myocardial infarction (mortality, 11%). On follow-up (mean, 5 years), 6 patients with cholecystectomy (in 1 case it was performed 2 months after the initial operation) and 1 patient with enterolithotomy alone are well; there was 1 death from an unrelated cause after 1 year.
Conclusion. It seems that a one-stage procedure (enterolithotomy plus fistula repair and cholecystectomy), when feasible, should be the first choice. Enterolithotomy alone should be reserved for only unstable and difficult cases. 相似文献

Gallstone disease(GD) is a chronic recurrent hepatobiliary disease,the basis for which is the impaired metabolism of cholesterol,bilirubin and bile acids,which is characterized by the formation of gallstones in the hepatic bile duct,common bile duct,or gallbladder.GD is one of the most prevalent gastrointestinal diseases with a substantial burden to health care systems.GD can result in serious outcomes,such as acute gallstone pancreatitis and gallbladder cancer.The epidemiology,pathogenesis and treatment of GD are discussed in this review.The prevalence of GD varies widely by region.The prevalence of gallstone disease has increased in recent years.This is connected with a change in lifestyle:reduction of motor activity,reduction of the physical load and changes to diets.One of the important benefits of early screening for gallstone disease is that ultrasonography can detect asymptomatic cases,which results in early treatment and the prevention of serious outcomes.The pathogenesis of GD is suggested to be multifactorial and probably develops from complex interactions between many genetic and environmental factors.It suggests that corticosteroids and oral contraceptives,which contain hormones related to steroid hormones,may be regarded as a model system of cholelithiasis development in man.The achievement in the study of the physiology of bile formation and the pathogenesis of GD has allowed expanding indications for therapeutic treatment of GD. 相似文献

AIM: To study the pathophysiological significance of gallbladder volume (GBV) and ejection fraction changes in gallstone patients.METHODS: The fasting GBV of gallstone patients with acute cholecystitis (n = 99), chronic cholecystitis (n = 85) and non-gallstone disease (n = 240) were measured by preoperative computed tomography. Direct saline injection measurements of GBV after cholecystectomy were also performed. The fasting and postprandial GBV of 65 patients with gallstones and chronic cholecystitis and 5... 相似文献

Background The cholinergic anti‐inflammatory pathway is proposed to be part of the so‐called vago‐vagal ‘inflammatory reflex’. The aim of this study is to provide neuro‐anatomical evidence to support the existence of a functional neuronal circuit and its activation in response to intestinal inflammation. Methods The expression of c‐fos was evaluated at different levels of the neurocircuitry in the course of postoperative ileus (POI) in a mouse model. Specific activation of the motor neurons innervating the inflamed intestine and the spleen was monitored by retrograde tracing using cholera toxin‐b. The role of the vagal afferent pathway nerve was evaluated by selective vagal denervation of the intestine. Key Results Abdominal surgery resulted in subtle inflammation of the manipulated intestine at 24 h (late phase), but not after 2 and 6 h (early) after surgery. This local inflammation was associated with activation of neurons in the nucleus of the solitary tract and in the dorsal nucleus of the vagus. The vagal output mainly targeted the inflamed zone: 42% of motor neurons innervating the intestine expressed c‐fos IR in contrast to 7% of those innervating the spleen. Vagal denervation of the intestine abolished c‐fos expression in the brain nuclei involved in the neuronal network activated by intestinal inflammation. Conclusions & Inferences Our data demonstrate that intestinal inflammation triggers a vagally mediated circuit leading mainly to activation of vagal motor neurons connected to the inflamed intestine. These findings for the first time provide neuro‐anatomical evidence for the existence of the endogenous ‘inflammatory reflex’ and its activation during inflammation. 相似文献

Intercostal hernias develop most often as a result of a blunt or penetrating thoracoabdominal trauma. We know of no prior report of a spontaneously occuring intercostal hernia. This study presents a review of the published literature that deals with this uncommon phenomenon, along with a discussion of our patient’s clinical presentation and imaging findings. 相似文献

目的 探讨男性居民吸烟、饮酒水平与胆石症患病的关系。方法 在广东省人群脂肪肝现况调查的基础上,选取成年男性居民,对其吸烟、饮酒水平与胆石症关系进行分析。结果 男性居民胆石症的患病率随着每天吸烟量的增加而升高(趋势χ^25.542,P=0.019),同时随着年吸烟总量的增加而不断升高(趋势χ^27.302,P=0.007),排除胆石症常见影响因素年龄和肥胖的影响后每天吸烟量以及年吸烟总量仍然是胆石症的危险因素(每天吸烟量OR=1.269,95%CI:1.018~1.580;吸烟总量OR=1.295,95%CI:1.020~1.646)。饮酒与胆石症的关系是少量和适量饮酒(〈40g/d)可降低男性居民的胆石症的发病,但大量饮酒(≥40g/d)反而会刺激胆石症的形成,呈现“V”形分布。排除胆石症常见影响因素年龄和肥胖的影响后,少量和适量饮酒的保护作用仍然存在(OR=0.537,95%CI:0.313~0.920)。每次饮酒量限制在20g内对胆石症的保护作用最强(OR=0.370,95CI:0.145~0.942)。每周饮酒频率不宜超过7次,饮酒年龄不宜过早,饮酒总年数不宜超过35a。结论 不吸烟、少量或适量饮酒可能对减少男性胆石症患病率有重要作用。 相似文献

A laparoscopic cholecystectomy (LC) was successfully performed on a 61-year-old man who had undergone coronary artery bypass
grafting (CABG) using the right gastroepiploic artery (RGEA). He complained of right hypochondralgia 20 days after CABG. Gallstones
were diagnosed and a cholecystectomy was performed 9 months after CABG. Under general anesthesia, the operation was performed
using a pneumoperitonium. When a laparoscope was inserted, the RGEA pedicle could be clearly recognized. The pedicle obstructed
the operating field and made the working space narrower than usual. No ST changes on the electrocardiogram were seen during
LC, especially during the initiation of pneumoperitonium, the insertion of the ports, or when retracting the gallbladder.
The postoperative course was uneventful. To avoid complications, care should be taken not to stretch the RGEA pedicle during
LC, and careful monitoring of the electrocardiogram is also necessary. It is difficult to view the operating field and the
RGEA pedicle together. It is therefore better to insert another laparoscope for concomitant monitoring of the RGEA pedicle.
