Objective To investigate the variation of total hospitalization cost for single-diagnosed disease of different types of acute appendicitis in a three-A hospital, so as to provide evidence for the reimbursement amount of social medical insurance. Methods All patients with acute appendicitis who had surgery treatment during January-April 2011 (before implementing the fee system for single-diagnosed disease) and January-April 2012 (after implementing the fee system for single-diagnosed disease) were collected in this study for analysis. According to the types of acute appendicitis, the patients were stratified into the low risk group (simple, suppurative and gangrenous) and the high risk group (perforative, abscess-formed and pregnancy-combined). The correlation between total hospitalization cost and types of acute appendicitis, as well as the changes of total hospitalization cost after implementing the fee system for single-diagnosed disease were analyzed. Results A total of 90 eligible patients were included. The disease types were positively correlated with hospital stays and total hospitalization cost. All three types in the low risk group could control the average total hospitalization cost within RMB 10 000 yuan. The results of sensitivity analysis showed that, before implementing the fee system for single-diagnosed disease, the total hospitalization cost up to RMB 6 000 yuan could be positively correlated with the above risk stratification (r=0.442, P=0.003). After implementing the fee system for single-diagnosed disease from January to April 2012, the constituent ratio of hospital stays, compared with that in the same period of 2011, had no significant difference (P=0.108) between the two groups; but the ratio of hospital stays (less than 5 days) increased from 45% to 64%, and the ratio of hospital stays (greater than or equal to 10 days) decreased from 17% to 4%, indicating a tendency of shortening hospital stays. Also, the constituent ratio of total hospitalization cost had no significant difference (P=0.114) between the two groups; but the ratio of total hospitalization cost (greater than or equal to RMB 9 000 yuan) decreased from 32% to 13%, indicating a tendency of lowering total hospitalization cost. Conclusion The low risk group of acute appendicitis, RMB 6 000 yuan should be rated as the rational reimbursement amount of social medical insurance. The total hospitalization cost for the high risk group is quite various, so the further studies are needed to investigate the feasibility of the fee system for single-diagnosed disease as well as the rating amount of total hospitalization cost. The implementation of the fee system for single-diagnosed disease is helpful to shorten hospital stays and reduce total hospitalization cost.
ObjectiveTo study the diagnostic significance of modified Alvarado Score System for different types of acute appendicitis. MethodsClinical data of 1 930 cases of acute appendicitis, who underwent appendicectomy in The First Hospital of Yulin from Jan. 2004 to Jan. 2014, were retrospectively collected. Then the diagnostic significance of Modified Alvarado Score System was detected and evaluated by receiver operating characteristic (ROC) curve, and its correlation with postoperative pathological results was calculated. ResultsThe modified Alvarado score of cases in progressive group was higher than that of simplex group (7.5±1.3 vs. 3.6±0.7, P < 0.001). The areas under ROC curve of modified Alvarado Score System was 0.943 (95% CI:0.929-0.958, P < 0.001). The critically diagnostic points of Modified Alvarado Score System for differential diagnosis of simplex acute appendicitis and progressive acute appendicitis was 6 score, with sensitivity of 92.9%, specificity of 86.3%, positive predictive value of 96.9%, negative predictive value of 72.6%, positive likelihood ratio of 6.8, negative likelihood ratio of 0.1, and Youden index of 91.7%. ConclusionThis Modified Alvarado Score System has a certain significance for the type diagnosis of acute appendicitis.
目的 分析急性阑尾炎及易与之混淆的其他急腹症的CT图像特征，探讨CT检查对急性阑尾炎诊断及鉴别诊断思路的辅助意义。方法 收集2009年6月至2012年6月期间南方医科大学附属小榄医院收治的120例初步诊断为急性阑尾炎患者的CT影像资料，回顾性分析和对比CT征象，研究其与最终诊断之间的内在联系。结果 120例患者中，单纯性阑尾炎15例，化脓性阑尾炎45例，阑尾坏疽、穿孔25例，阑尾脓肿10例；其他急腹症20例；5例未确诊。阑尾炎患者的术前CT征象因阑尾炎种类不同而略有区别，有56例发现粪石；而其他急腹症的CT征象有结肠管壁局限性增厚、肾输尿管高密度影、肾周筋膜增厚、子宫附件区囊性或实性肿物、肠系膜淋巴结肿大、腹水等。结论 CT检查对急性阑尾炎诊断与鉴别诊断思路的形成具有重要的价值。
目的 比较低频与高频探头超声对急性阑尾炎的诊断价值。 方法 对2010年1月－2011年6月120例急性阑尾炎的手术病理结果与超声检查结果进行回顾性分析，比较低、高频探头超声对急性阑尾炎的诊断价值。 结果 120例急性阑尾炎中，通过低频探头超声检出67例（55.8%），通过高频探头超声检出105例（87.5%）；单纯性阑尾炎以及化脓性和坏疽性阑尾炎高频探头超声检出例数明显大于低频探头超声，差异有统计学意义（P＜0.05）；阑尾周围脓肿低、高频探头超声均全部检出。 结论 高频探头超声对急性阑尾炎的检出率高于低频探头超声，但二者各有所长，在临床中联合应用能有效提高急性阑尾炎的超声诊断符合率。
目的 探讨急性阑尾炎手术后切口感染的相关因素。方法 观察我院2002年5月至2007年5月期间收治的665例急性阑尾炎患者采用术前预防使用抗生素、术中保护切口、术后加强切口管理等处理后切口感染情况，并分析切口感染与阑尾炎的病程、手术时间、切口选择、留置引流和病理类型之间的关系。结果 本组患者中32例发生切口感染，感染率为4.81% (32/665)，急性阑尾炎术后切口感染与性别无关（ P ＞ 0.05），与病程长短、切口选择、手术时间、腹腔留置引流与否以及病理类型均有关（ P ＜ 0.01）。结论 病程长、手术时间久、炎症较重的急性阑尾炎病例切口感染率较高； 做好围手术期的处理，术中尽量保护切口可以降低切口感染率。
ObjectiveTo compare the outcomes of laparoscopic appendectomy (LA) and open appendectomy (OA) for the acute appendicitis patients based on our extensive experiences. MethodsThe data of all the acute appendicitis patients who underwent appendectomy from January 2013 to December 2014 in our department were retrospectively reviewed. A total of 201 patients were enrolled and divided into LA group (n=102) and OA group (n=99). The relevant clinical indexes during and after operation of two groups were compared. ResultsThere were no significant difference in age, gender, and underlying disease between LA and OA patients (P > 0.05). And the abdominal cavity infection rate, abdominal drainage rate and 30-day readmission rate were also similar (P > 0.05). But LA group had less operative time, lower infection operative wound rate, less intestinal function recovery time, shorter inhospital days and higher hospital expenses than OA group (P < 0. 05). In addition, perforated appendix and LA could increase the rate of abdominal drainage[OR=2.710, 95% CI(1.129, 6.507), P=0.026]. ConclusionsBoth LA and OA are safe and effective methods for the treatment of acute appendicitis. But LA has several advantages over OA on less operative time and postoperative complications, earlier recovery, and shorter inhospital days. While LA have higher hospital cost than OA, it still should be considered as a prefer way to cure acute appendicitis. LA is a independent risk factor of abdominal drainage.
ObjectiveTo investigate the efficacy and safety of laparoscopic surgery for overweight/obese patients with acute perforated or gangrenous appendicitis. MethodsFrom January 2007 to December 2014, patients with acute perforated or gangrenous appendicitis underwent laparoscopic (152 cases) or open (60 cases) appendectomy were collected, who were retrospectively classified into overweight/obese group (BMI≥25 kg/m2, n=69) or normal weight group (BMI < 25 kg/m2, n=143). Conversion rate, operation time, hospital stay, readmission, reoperation, and postoperative complications such as incision infection, abdominal abscess, and lung infection were analyzed. Results①The rate of conversion to open surgery had no significant difference between the overweight/obese group and the normal weight group[4.2% (2/48) versus 6.7% (7/104), χ2=0.06, P > 0.05].②The operation time of laparoscopic surgery in the overweight/obese group was significantly shorter than that of the open surgery in the overweight/obese group[(41.6±11.7) min versus (63.1±23.3) min, P < 0.01], which had no significant difference between the laparoscopic surgery in the overweight/obese group and laparoscopic surgery in the normal weight group[(41.6±11.7) min versus (39.6±12.7) min, P > 0.05].③The total complications rate and incision infection rate of the laparoscopic surgery in the overweight/obese group were significantly lower than those of the open surgery in the overweight/obese group[total complications rate:16.7% (8/48) versus 52.4% (11/21), χ2=9.34, P < 0.01; incision infection rate:4.2% (2/48) versus 33.3% (7/21), χ2=8.54, P < 0.01]. Although the total complications rate of all the patients in the overweight/obese group was increased as compared with all the patients in the normal weight group[27.5% (19/69) versus 14.7% (21/143), χ2=5.02, P < 0.01], but which had no significant difference between the laparoscopic surgery in the overweight/obese group and laparoscopic surgery in the normal weight group[16.7% (8/48) versus 12.5% (13/104), χ2=0.45, P > 0.05].④The reoperation rate of all the patients performed laparoscopic surgery was significantly lower than that of all the patients performed open operation[1.3% (2/152) versus 10.0% (6/60), χ2=6.7, P < 0.01].⑤The abdominal abscess rate, lung infection rate, and hospital stay after discharge had no significant differences among all the patients (P > 0.05). ConclusionLaparoscopic appendectomy could be considered a safe technique for overweight/obese patients with acute perforated or gangrenous appendicitis, which could not increase the difficulty of laparoscopic surgery and the perioperative risk.
