胆源性胰腺炎手术时机的探讨 总被引:88,自引:1,他引:88
目的探讨胆源性胰腺炎(GP)的手术时机。方法采用统计学方法分析了53例GP的临床资料。结果早期手术组(入院48小时内)及延期手术组(入院48小时后)并发症发生率分别为29.20%和3.50%(P<0.05);死亡率分别为8.30%和0(P<0.05)。APACHE-Ⅱ记分≤8的轻型GP死亡率与手术时机无关,但早期手术组的并发症发生率(11.10%)及胆总管探查率(91.70%)明显高于延期手术组(P<0.05)。APACHE-Ⅱ记分>8的重型GP并发症发生率及死亡率与手术时机有关,即早期手术组明显高于延期手术组。结论轻型GP应待急性发作缓解后延期手术;重型GP应采用延期与个体化相结合的处理原则。 相似文献

尿素动力学模型在持续性非卧床腹膜透析中的应用 总被引:1,自引:0,他引:1
对20例ESRD患者先后给予持续性非卧床膜腹膜透析(CAPD)1L×5/d和2L×4/d方案透析,测定其尿素清除指数(KT/V)和标化每日蛋白质分解率(NPCR),同时应用12个临床参数对两方案进行疗效评价.结果显示由IL×5/d改为2L×4/d时,KT/V和NPCR分别上升0.74±0.21和0.12±0.09(P<0.001),临床有效率上升80%(P<0.005);NPCR和KT/V呈正相关(r=0.49,P<0.05).NPCR与每日蛋白质摄入量(DPI)呈高度正相关(r=0.91,P<0.001),KT/V与临床评分也呈正相关(r=0.61,P<0.01).结果表明尿素动力学模型对评价CAPD治疗具有重要意义. 相似文献

重症胰腺炎手术指征和手术时机的探讨 总被引:13,自引:0,他引:13
目的 探讨重症且腺炎的手术指征和手术时机。方法 回顾性分析82例重症胰腺炎的治疗情况,其中行非手术治疗10例、早期手术44例、延期手术28例。结果 本组总并发症发生率为24%、总病死率为18%。非手术组10例均痊愈,并发症发生率为10%;早期手术组死亡5例,并发症经和病死率分别为14%和11%;延期手术组死亡10例,并发症发生率和病死率分别为46%和36%,两组相比差异有显著意义(P<0.01、P<0.05)。延期手术组中,无明显感染者其并发症发生率和病死率明显低于有严重感染及重要器官功能不全者(P<0.01、P<0.05)。结论 早期手术治疗对于一些重症胰腺炎患者仍然是必需的。胰腺坏死广泛者宜在发生严惩感染前进行手术。 相似文献

不同心脏病人心肺转流期间肺顺应性的动态观察 总被引:1,自引:0,他引:1
本文观察了两组心内直视手术病人心肺转流前后肺顺应性的动态变化。结果发现先心组病人(n=14)转流期间胸肺顺应性(Cs)和动态肺顺应性(Cd)均显著降低(P<0.01),停机20min和术毕时仍低于转流前(P<0.01);瓣膜组(n=11)Cs、Cd值转流期间亦同样降低(P<0.01),但转流后期至术毕渐回升至对照水平(P>0.05)。认为两类病人不同的肺部病理生理特点是造成转流中、后期肺顺应性呈不同变化的基础。体外循环本身可造成两类病人肺顺应性的降低,引起上述变化的确切因素仍待进一步探讨。 相似文献

作者通过给豚鼠注射外源性胰岛素,观察官对豚鼠的胆汁酸代谢、肝脏形态及胆石形成的影响。结果发现:①实验组(n=12)7只豚鼠有胆石形成,成石率58%,而对照组(n=15)中仅1只有胆石形成,成石率6.7%,两组间有显著性差异(P<0.05);②实验组豚鼠肝脏中央静脉周围有空泡变性及脂肪细胞沉积,对照组豚鼠则少见;③实验组豚鼠胆囊胆汁中牛磺鹅脱氧胆酸(TCDCA)与甘氨鹅脱氧胆酸(GCDCA)分别为0.597±0.39mg/ml与2.421±1.59mg/ml,而对照组分别为0.757±0.43mg/ml与3.265±2.47mg/ml,两组间也有显著性差异(P<0.01)。上述实验结果表明,外源性胰岛素可引起肝脏的空泡变性,进而使胆汁中结合胆汁酸含量降低,促进胆石形成。 相似文献

Timing of laparoscopic cholecystectomy for acute cholecystitis: evidence to support a proposal for an early interval surgery 总被引:3,自引:0,他引:3
We evaluated the safety and feasibility of delayed urgent laparoscopic cholecystectomy (LC) performed beyond 72 hours to overcome the logistical difficulties in performing early urgent LC within 72 hours of admission with acute cholecystitis (AC), and to avoid earlier readmission with recurrent AC in patients awaiting delayed interval. Patients admitted with AC were scheduled for urgent LC. Patients who underwent early urgent LC were compared with those who had delayed urgent surgery. Fifty consecutive patients underwent urgent LC for AC within 2 weeks of admission. There were no conversions and no bile duct injuries. Delayed surgery (n=36) neither prolonged operating time (90 vs. 85 minutes), nor increased operative morbidity (9.7% vs. 7.7%) or mortality (2.4% vs. 7.7%) compared with early surgery (n=14). Although delayed surgery was associated with shorter postoperative hospital stay (1 vs. 2 days, P = 0.029), it prolonged total hospital stay (9 vs. 5 days, P < 0.0001). Delay of LC beyond 72 hours neither increases operative difficulty nor prolongs recovery. It might be more cost effective to schedule patients who could not undergo early urgent LC but are responding to conservative treatment for an early interval LC within 2 weeks of presentation with AC. 相似文献

A 10-year experience with the use of laparoscopic cholecystectomy for acute cholecystitis: is it safe? 总被引:8,自引:0,他引:8
BACKGROUND: In the era of open surgery, emergency open cholecystectomy has been shown for many reasons to be preferred to delayed surgery for acute cholecystitis. Despite the fact that elective laparoscopic cholecystectomy (LC) has become the gold standard for the treatment of symptomatic gallstone disease, the same procedure remains controversial for the management of acute cholecystitis because it is considered to be associated with more complications and an increased risk of common bile duct injuries than interval LC after resolution of the acute episode. The purpose of this report is to describe our experience with LC for acute cholecystitis during a 10-year period. METHODS: Patients undergoing laparoscopic surgery have been entered prospectively into a database since 1995. Those who underwent surgery before 1995 were added retrospectively to the same database. Patients were included in this study if they underwent emergency laparoscopic cholecystectomy for suspected acute cholecystitis. The diagnosis was based on clinical, laboratory, and echographic examinations. Analysis was performed to identify risk factors associated with conversion or morbidity. RESULTS: Of the 1,212 patients subjected to LC between 1990 and 1999, 268 (151 women and 117 men), with a mean age of 53 years, underwent surgery on an emergency basis for suspected acute cholecystitis. Their mean age (p = 0.002) and the proportion of men (p < 0.001) were higher than in the elective group. Delay before admission and surgery varied widely, but 72% of the patients underwent surgery within 48 h of admission. An intraoperative cholangiography, attempted in 218 patients, was successful in 207 (95%). Histologic examination confirmed acute cholecystitis in 82% of the patients. Conversion was necessary in 15.6% of the cases. It occurred more frequently in patients who underwent surgery later than 48 (p = 0.03) or 96 h (p = 0.006) after admission. No other predictor of conversion was found. Overall morbidity was 15.3%, and major morbidity was 4.4%. The only risk factor for morbidity was a bilirubin level greater than 20 mmol/l (p = 0.02). Three partial lesions of the common bile duct occurred. All were recognised and repaired immediately with no adverse effect. There was no difference in the overall rate of biliary complications between the patients operated for acute cholecystitis and those who underwent elective surgery. No reoperation was necessary, and there was no mortality. CONCLUSIONS: Although LC is safe and effective for acute cholecystitis, its associated morbidity and conversion rate are higher than for elective LC. The conversion rate decreases with experience. When surgery is performed within 2 or maximally 4 days of admission, in experienced hands, LC represents the treatment of choice for acute cholecystitis. Intraoperative cholangiography should be performed in every case because it helps to clarify the anatomy and allows for early diagnosis and repair of bile duct injuries. 相似文献

OBJECTIVE: A prospective randomized study was undertaken to compare early with delayed laparoscopic cholecystectomy for acute cholecystitis. SUMMARY BACKGROUND DATA: Laparoscopic cholecystectomy for acute cholecystitis is associated with high complication and conversion rates. It is not known whether there is a role for initial conservative treatment followed by interval elective operation. METHOD: During a 26-month period, 99 patients with a clinical diagnosis of acute cholecystitis were randomly assigned to early laparoscopic cholecystectomy within 72 hours of admission (early group, n = 49) or delayed interval surgery after initial medical treatment (delayed group, n = 50). Thirteen patients (four in the early group and nine in the delayed group) were excluded because of refusal of operation (n = 6), misdiagnosis (n = 5), contraindication for surgery (n = 1), or loss to follow-up (n = 1). RESULTS: Eight of 41 patients in the delayed group underwent urgent operation at a median of 63 hours (range, 32 to 140 hours) after admission because of spreading peritonitis (n = 3) and persistent fever (n = 5). Although the delayed group required less frequent modifications in operative technique and a shorter operative time, there was a tendency toward a higher conversion rate (23% vs. 11%; p = 0.174) and complication rate (29% vs. 13%; p = 0.07). For 38 patients with symptoms exceeding 72 hours before admission, the conversion rate remained high after delayed surgery (30% vs. 17%; p = 0.454). In addition, delayed laparoscopic cholecystectomy prolonged the total hospital stay (11 days vs. 6 days; p < 0.001) and recuperation period (19 days vs. 12 days; p < 0.001). CONCLUSIONS: Initial conservative treatment followed by delayed interval surgery cannot reduce the morbidity and conversion rate of laparoscopic cholecystectomy for acute cholecystitis. Early operation within 72 hours of admission has both medical and socioeconomic benefits and is the preferred approach for patients managed by surgeons with adequate experience in laparoscopic cholecystectomy. 相似文献
