腹腔镜胆囊切除术前超声内镜检查胆总管必要性的探讨

目的 探讨腹腔镜胆囊切除（laparoscopic cholecystectomy,LC）术前超声内镜（endoscopic ultrasonography,EUS）检查胆总管的临床价值。方法 对25例术前经腹超声检查诊断胆囊结石,胆总管内径〉0.7 cm可疑胆总管梗阻的患者进行EUS检查,并与手术结果或内镜十二指肠乳头切开术（endoscopic sphincterotomy,EST）取石结果进行比较。结果 EUS对于胆总管病变诊断的敏感性、准确性和阴性预测值[100%（17/17）、92%（23/25）、100%（6/6）]均优于经腹超声[35%（6/17）、56%（14/25）、42%（8/19）]（P=0.000,0.008,0.020）。结论EUS对胆总管病变诊断优于经腹超声检查,可作为术前常规检查,特别是当胆总管内径〉1.0 cm时,EUS应作为术前必检项目。     

Early laparoscopic cholecystectomy for acute cholecystitis

Background: The timing of laparoscopic cholecystectomy for acute cholecystitis remains controversial. Methods: One hundred ninety-four patients with acute cholecystitis were reviewed. The conversion rates for the various number of days of symptoms before surgery were analyzed. The conversion rate dramatically increased from 3.6% for those patients with 4 days of symptoms to 26% for those patients with 5 days of symptoms. The mean number of days of symptoms prior to surgery in those patients who underwent successful laparoscopic cholecystectomy was 4.1 as compared to 8.0 in those patients who required open cholecystectomy (p < 0.0001). Based on this data the patients were divided into two groups. Group 1 consisted of 109 patients who underwent laparoscopic cholecystectomy within 4 days of onset of symptoms and group 2 consisted of 85 patients who underwent laparoscopic cholecystectomy after more than 4 days following onset of symptoms. Results: The conversion rate from laparoscopic to open cholecystectomy was 15%. The conversion rate for group 1 was 1.8% as compared to 31.7% for group 2 (p < 0.0001). Indications for conversion were inability to identify the anatomy secondary to inflammatory adhesions (68%), cholecystoduodenal fistula (18%), and bleeding (14%). The major complication rate for group 1 was 2.7% as compared to 13% for group 2 (p= 0.007). The mortality rate for all patients with attempted laparoscopic cholecystectomy for acute cholecystitis was 1.5%. The average procedure time for group 1 was 100 ± 37 min vs 120 ± 55 min in group 2. The average number of postoperative hospital days in group 1 was 5.5 ± 2.7 days as compared to 10.8 ± 2.7 days in group 2. Conclusions: We advocate early laparoscopic cholecystectomy within 4 days of onset of symptoms to decrease major complications and conversion rates. This decreased conversion rate results in decreased length of procedure and hospital stay. Received: 28 March 1996/Accepted: 12 September 1996     

Initial results of a prospective trial of outpatient laparoscopic cholecystectomy

Background: Whether or not laparoscopic cholecystectomy may be performed safely as an outpatient procedure is controversial. In 1993, a protocol for outpatient laparoscopic cholecystectomy was instituted to determine the benefits and safety of discharging patients within several hours of surgery. Methods: The initial 60 outpatient laparoscopic cholecystectomies performed by one surgeon in a hospital-based outpatient teaching facility between February 1993 to June 1996 were prospectively studied. Results: Fifty-eight (97%) patients were discharged successfully after an average stay in the recovery room of 3 h. There were no deaths. Two patients required overnight observation and three patients required readmission. Two patients (3%) had cystic duct leak. The average hospital stay for all patients undergoing laparoscopic cholecystectomy at the institution (inpatient and outpatient) decreased from 3.2 to 1.5 days and the average hospital cost decreased from $7,800 to $4,600 during this period. Conclusion: Laparoscopic cholecystectomy in an outpatient setting is safe and cost-effective in healthy patients. Received: 3 April 1997/Accepted: 10 June 1997     

老年人腹腔镜胆囊切除术118例报告

目的探讨老年人腹腔镜胆囊切除术（laparoscopic cholecystectomy，LC）的特点。方法回顾性分析2000年1月～2005年1月我院收治的118例老年病人LC的临床资料。结果116例顺利施行LC，中转开腹手术2例，其中1例为胆囊管开口于胆总管下端，另1例胆总管损伤。LC手术时间30～120min，平均50min。术后均恢复顺利。术后住院3～7d，平均4．5d。1例胆总管损伤术后随访2年6个月，有短暂的腹痛和发热，应用抗生素2—5d后症状消失，无胆道狭窄和胆道结石。余117例术后随访6～12个月，平均10．5月，无腹痛、发热、黄疸等并发症。结论老年人可耐受LC，且安全可靠，充分的围手术期处理、仔细的手术操作是成功的关键。

Techniques for difficult cases of laparoscopic cholecystectomy

Our basic techniques for the management of difficult cases of laparoscopic cholecystectomy (LC) are presented in this article. If access to Calot's triangle cannot be gained safely, dissection should be started at the fundus or body of the gallbladder (GB), rather than the neck (fundus-first method). In cases with a short and wide cystic duct, a transfixing suture should be applied for ligation instead of clipping. EndoGIA is useful for ligating and transecting this case to avoid a subsequent stricture caused by normal method of ligation. Intraoperative cholangiography should be performed near the neck of the GB in cases in which orientation is lost during dissection. More dissection should be performed in the direction of the junction of the bile ducts after orientation is regained. In cases with GB filled with stones accompanied by severe fibrosis, part of the GB is incised to remove the stones and expose the lumen of the GB. Confluence stones can be removed by placing an incision on the GB side of the junction of the duct. The incised part is closed with suture. A cystic tube (C-tube) is placed in the common bile duct through the cystic duct for decompression. In more difficult cases in which dissection cannot be started safely at any location, the body and the fundus of the GB are excised, and a drain is placed at the neck of the GB. Dissection can be carried out from the main surgeon's or the assistant's side depending on the situation, and cooperation between the two surgeons is mandatory to achieve safe LC in difficult cases. When performing the LC, one must have a low threshold for converting to open surgery if injuries cannot be managed safely.     

The impact of laparoscopic cholecystectomy on the treatment of symptomatic cholelithiasis

Background: There has been a debate about the cost-effectiveness of laparoscopic cholecystectomy (LC), as well as a concern regarding its possible overutilization and changes in the indication for surgery. Methods: A retrospective analysis of all cholecystectomies performed at UCDMC from 1988 to 1994 was done. The annual rate of cholecystectomy increased by 50% in 1990 when LC was introduced but has since stabilized at a rate 11% higher than the rate before LC. The disease status and severity did not change. Results: The incidence of nonelective surgery remained stable at 31.2% to 37.5%. Elective cholecystectomy had lower mortality (0.16% vs 1.8%, P=0.029), morbidity (2.6% vs 11.2%, P=0.0001), and conversion rate (2.6% vs 16%, P=0.0001) and a shorter length of stay (2.1 days vs 5.4 days), compared with nonelective procedure. Conclusions: The indication for surgery in cholelithiasis has not changed since the introduction of LC. In patients with symptomatic gallstones, early elective surgery is recommended and may be more cost-effective.Presented at the annual meeting of the Society of American Gastrointestinal Endoscopic Surgeons (SAGES), Orlando, FL, March 12–14, 1995
