目的 分析其他疾病误诊为急性阑尾炎的原因。方法 结合相关文献资料，对2004年2月至2008年12月期间本院21例其他疾病被误诊为急性阑尾炎的过程进行回顾性分析。结果 除了胆囊结石、胃穿孔、肠结核、异位妊娠等常见病可能被误诊为急性阑尾炎外，肝包虫、胆管癌、癔病、恶性淋巴瘤等也有可能被误诊为急性阑尾炎。误诊的主要原因是经治医生经验不足、思维局限、知识面狭窄，更重要的则是重视不足，检查不仔细、不全面。结论 系统和全面仔细地问诊、查体，努力提高辅助检查诊断水平等是减少误诊的关键。
Objective To investigate the clinical features, diagnosis, and surgical methods of left-sided appendicitis (LSA). Methods We retrieved LSA-related literatures through Pubmed, Google Scholar English databases, Wanfang, CNKI, VIP, and SinoMed databases (published from January 1981 to June 2017), as well as 2 cases of LSA who treated in Beibei Traditional Chinese Medical Hospital, to analyze the clinical characteristics of LSA and its diagnosis and treatment methods. Results There were 92 articles in a total of 212 LSA patients were retrieved, and 2 cases treated in Beibei Traditional Chinese Medical Hospital, a total of 214 LSA patients were included in the analysis. Pain fixed position of LSA: 139 cases (65.0%) located in left-lower quadrant, 30 cases (14.0%) located in right-lower quadrant, 8 cases (3.7%) located in peri-umbilical, 15 cases (7.0%) located in mid-lower abdomen, 15 cases (7.0%) located in left-upper quadrant, 3 cases (1.4%) located in right-upper abdomen, 2 cases (0.9%) located in mid-upper abdomen, 2 cases (0.9%) located in pelvic cavity, respectively. LSA had occurred in association with several types of abnormal anomalies: 131 cases (61.2%) suffered from situs inversus totalis (SIT), 53 cases (24.8%) suffered from midgut malrotation (MM), 21 cases (9.8%) suffered from cecal malrotation, 4 cases (1.9%) suffered from long appendix, 2 cases (0.9%) suffered from free ascending colon, and 3 cases (1.4%) were unclear. The diagnosis of 114 LSA cases (53.3%) before operation was correct, in which the correct diagnosis rates of SIT-LSA and MM-LSA were 74.8% (98/131) and 22.6% (12/53), respectively. Three patients (1.4%) underwent conservative treatment, and 211 patients (98.6%) underwent surgical treatment, including 25 cases (11.7%) of laparoscopic surgery, 145 cases (67.8%) of open abdominal surgery, and unknown of 41 cases (19.1%). Laparotomy incision: abdominal incision in 74 cases (51.0%), ventral midline incision in 16 cases (11.0%), the left side of the anti McBurney incision in 43 cases (29.7%), right McBurney incision in 12 cases (8.3%). Conclusions LSA mainly occurs in association with 2 types of congenital anomalies: SIT and MM. There is some difficult to make diagnosis for abnormal anatomy and inaccurate pain location of LSA, so it is easy to cause the delay in diagnosis or misdiagnosis. For LSA, the choices of laparoscopy or laparotomy operation methods are applicable.
ObjectivesTo assess the predictive value of neutrophils-to-lymphocytes ratio (NLR) in the diagnosis of children complicated appendicitis.MethodsThe clinical data of patients with acute appendicitis treated in Department of Pediatric Surgery, the Second Affiliated Hospital of Xi’an Jiaotong University from January 2014 to June 2017 were analyzed retrospectively. Based on the pathology results, patients were divided into two groups: simple appendicitis and complicated appendicitis. The differences of age, gender, disease time, fever, highest temperature, emesis, right lower abdominal pain, blood indicators, and ultrasound results between the two groups were analyzed. Useful parameters to aid in the diagnosis of children complicated appendicitis were screened through single-factor and multiple-factor analysis. The predictive value of the parameters was evaluated by ROC analysis, sensitivity and specificity.ResultsA total of 235 patients was evaluated and divided into simple appendicitis group (179 patients) and complicated appendicitis group (56 patients). Logistic regression analysis revealed that NLR was the independent risk factor for diagnosis of children complicated appendicitis. When NLR>11.74, the Youden index for predictive complicated appendicitis was the biggest, reaching 0.325, and the sensitivity and specificity were 47.8% and 84.7%, respectively (OR=3.121, 95%CI 2.036 to 4.783).ConclusionsThe preoperative NLR is a certain indicator for predicting children complicated appendicitis, and can be used as reference to whether or not receive an operation.
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 analyze risk factors associated with prognosis of appendiceal adenocarcinoma using data from the Surveillance, Epidemiology, and End Results (SEER) database. MethodsThe patients pathologically diagnosed with appendiceal adenocarcinoma from 2005 to 2015 were extracted from the SEER database and then randomly divided into a training cohort and validation cohort in a 7∶3 ratio. The univariate and multivariate Cox regression analyses were performed in the training cohort to identify the independent risk factors for overall survival and cancer-specific survival. Based on these factors, a nomogram prediction model was constructed and subsequently internally validated. The statistical significance was defined as α=0.05. ResultsA total of 749 patients with appendiceal adenocarcinoma were enrolled, with 524 in the training cohort and 225 in the validation cohort. The multivariate Cox regression analysis identified that the T, N, M stages, and surgery as the independent prognostic factors for both overall survival and cancer-specific survival. Additionally, the age was identified as an independent prognostic factor for overall survival, and tumor size for cancer-specific survival. Based on these factors, the nomogram prediction models for the overall survival rate and cancer-specific survival rate were developed. The nomogram of overall survival rate achieved a C-index of 0.716 [95%CI=(0.689, 0.743)] in the training cohort and 0.695 [95%CI=(0.649, 0.740)] in the validation cohort, while the nomogram of cancer-specific survival rate showed C-index values of 0.749 [95%CI=(0.716,0.782)] and 0.746 [95%CI=(0.699, 0.793)], respectively. The area under the receiver operating characteristic curves (AUCs) for 3- and 5-year overall survival rates were 0.780 [95%CI=(0.739, 0.821)] and 0.773 [95%CI=(0.732, 0.814)] respectively in the training cohort, were 0.789 [95%CI=(0.726, 0.852)] and 0.776 [95%CI=(0.715, 0.837)] respectively in the validation cohort, which for 3- and 5-year cancer-specific survival rates were 0.813 [95%CI=(0.768, 0.858)] and 0.796 [95%CI=(0.753, 0.839)] respectively in the training cohort, were 0.813 [95%CI=(0.750, 0.876)] and 0.811 [95%CI=(0.750, 0.872)] respectively in the validation cohort. The calibration curves demonstrated good agreements between predicted and observed outcomes for both overall survival rate and cancer-specific survival rate. ConclusionsThrough analysis results of appendiceal adenocarcinoma patients from the SEER database reveal that advanced T, N, and M stages, as well as lack of surgery are significant risk factors for both overall survival and cancer-specific survival. The constructed nomograms for predicting overall survival and cancer-specific survival rates, which incorporate these risk factors, demonstrate strong predictive accuracy.
