Background
Despite the initial absolute or relative contraindication of laparoscopic surgery during pregnancy, in the last decade, laparoscopic appendectomy (LA) has been performed in pregnant women. But few studies compare the outcomes of LA compared with open appendectomy (OA). We investigated clinical outcomes to evaluate the safety and efficacy of LA compared with OA in pregnant women.Methods
We recruited consecutive pregnant patients with a diagnosis of acute appendicitis who were undergoing LA or OA between May 2007 and August 2011 into the study.Results
Sixty-one patients (22 LA and 39 OA) enrolled in our study. There were no significant differences in duration of surgery, postoperative complication rate and obstetric and fetal outcomes, including incidence of preterm labour, delivery type, gestation age at delivery, birth weight and APGAR scores between the 2 groups. However, the LA group had shorter time to first flatus (2.4 ± 0.4 d v. 4.0 ± 1.7 d, p = 0.034), earlier time to oral intake (2.3 ± 1.6 d v. 4.1 ± 1.9 d, p = 0.023) and shorter postoperative hospital stay (4.2 ± 2.9 d v. 6.9 ± 3.7 d, p = 0.043) than the OA group.Conclusion
Laparoscopic appendectomy is a clinically safe and effective procedure in all trimesters of pregnancy and should be considered as a standard treatment alternative to OA. Further evaluation including prospective randomized clinical trials comparing LA with OA are needed to confirm our results. 相似文献2.

Introduction
Diagnostic laparoscopy with appendicectomy (LA) has become the accepted method of investigation and treatment of appendicitis. However, concerns remain in cases of complicated appendicitis when many advocate conversion to an open procedure (LCOA) owing to the risk of complications. The aim of this study was to look for factors that could predict complications occurring in patients undergoing appendicectomy.Methods
Data inclusive of all consecutive appendicectomies over a two-year period were retrieved from the computerised theatre database. Clinical details including admission inflammatory markers, complications, severity (final pathology) and length of stay were collected from the discharge letter. Readmissions were identified as those hospital identifiers had a second set of admission dates and/or a second discharge letter.Results
During the 2-year study period, 517 appendicectomies were performed. Of these, 429 patients (83%) had LA and the remaining 88 (17%) had LCOA. The LA group had a mean age of 28 years (range: 2–86 years) and a mean C-reactive protein (CRP) level of 71mg/l (range: 0–480mg/l) while the LCOA group had a mean age of 46 years (range: 11–92 years) and a mean CRP level of 162mg/l (range: 3–404mg/l). These differences in age and CRP were significant (p<0.001). LA patients were less likely to have complications overall (22% vs 52%, p=0.015). Complications were independently more than twice as common with established inflammation with a CRP level of >150mg/l (p<0.05).Conclusions
A high preoperative CRP level predicts an increased rate of postoperative complication due to established inflammation and/or infection. This raises the question of whether we should be offering primary open appendicectomies to patients with a CRP level of >150mg/l. 相似文献3.

Background
Knee and hip arthroplasty constitutes a large percentage of hospital elective surgical procedures. The Blaylock Risk Assessment Screening Score (BRASS) was designed to identify patients in need of discharge planning. The purpose of this study was to evaluate whether the BRASS was associated with length of stay (LOS) in hospital following elective arthroplasty.Methods
We retrospectively reviewed the charts of individuals undergoing primary elective arthroplasty for knee or hip osteoarthritis who had a documented BRASS score.Results
In our study cohort of 241, both BRASS (p < 0.001) and replacement type (hip v. knee; p = 0.048) were predictive of LOS. Higher BRASS was associated with older patients (p < 0.001), higher American Society of Anesthesiologists score (p < 0.001) and longer LOS (p < 0.001). We found a specificity of 83% for a BRASS greater than 8 and a hospital stay longer than 5 days and a specificity of 92% for a BRASS greater than 10.Conclusion
The BRASS represents a novel and significant predictor of LOS following elective arthroplasty. Patients with higher BRASS are more likely to stay in hospital 5 days or more and should receive pre-emptive social work consultations to facilitate timely discharge planning and hospital resources. 相似文献4.

Objective
To evaluate the influence of age on the evolution and severity of peritonitis.Design
A chart review.Setting
An adult university hospital.Patients
One hundred and twenty-two patients with acute appendicitis and 100 patients with acute colonic diverticulitis requiring operation or percutaneous drainage.Main Outcome Measures
Patient age and sex, presence of perforation or gangrene (appendicitis), extent of peritonitis (diverticulitis); duration of symptoms prior to admission; admission leukocyte count; duration of hospitalization before surgery; length of hospital stay; and death rate.Results
Patients with acute appendicitis who were aged 65 years or older were three times more likely than younger patients to have a gangrenous or perforated appendix (odds ratio 3.1, 95% confidence interval 1.1 to 8.4, p < 0.05); older patients with perforated diverticulitis were three times more likely than younger patients to have generalized peritonitis than localized (pericolic or pelvic) peritonitis (odds ratio 2.9, 95% confidence interval 1.2 to 7.5, p < 0.05).Conclusion
These findings are consistent with the hypothesis that the biologic features of peritonitis differ in the elderly, who are more likely to present with an advanced or severe process than young patients. 相似文献5.

INTRODUCTION
The aim of this study was to review changes in the management of acute appendicitis in a ten-year period at a large university teaching hospital in London.METHODS
This was a retrospective cohort study reviewing the medical records of patients who underwent an appendicectomy over a period of 12 months either in 1999 or 2009. Data collected included use of radiological investigations (ultrasonography, computed tomography [CT]), technique of appendicectomy (open [OA] or laparoscopic [LA]), operative time, histopathology and post-operative complications. Univariate and multivariate analysis was performed to assess the influence of variables on the incidence of negative appendicectomy, appendiceal perforation and post-operative complications.RESULTS
All of the patients operated on in 1999 (n=109) had OA. Of the patients operated on in 2009 (n=164), 67 had OA, 91 had LA and 6 had LA converted to OA.None of the patients in 1999 had CT whereas in 2009 26% of patients had CT (sensitivity 94.7%, specificity 75.0%). This increased use of pre-operative imaging had no effect on negative appendicectomy (25.7% vs 12.8%, p=0.445), perforation (30.0% vs 21.3%, p=0.308) or complication rates (9.2% vs 10.4%). The complication rate was also similar regardless of whether patients had OA or LA (11.9% vs 9.9%). Multivariate analysis revealed that age was the only predictor of negative appendicectomy (p=0.029) or perforation (p=0.014).CONCLUSIONS
This study shows that significant increase in the use of pre-operative imaging and laparoscopy in the management of patients with acute appendicitis failed to reduce negative appendicectomy, perforation and complications rates. The patient''s age was the only predictor of negative appendicectomy and perforation. 相似文献6.

Background
Laparoscopic surgery has become the standard for treating appendicitis. The cosmetic benefits of using single-incision laparoscopy are well known, but its duration, complications and time to recovery have not been well documented. We compared 2 laparoscopic approaches for treating appendicitis and evaluated postoperative pain, complications and time to full recovery.Methods
We retrospectively reviewed the cases of consecutive patients with appendicitis and compared those who underwent conventional laparoscopic appendectomy (CLA) performed using 3 incisions and those who underwent single-incision laparoscopic appendectomy (SILA). During SILA, the single port was prepared to increase visibility of the operative site.Results
Our analysis included 688 consecutive patients: 618 who underwent CLA and 70 who underwent SILA. Postsurgical complications occurred more frequently in the CLA than the SILA group (18.1% v. 7.1%, p = 0.018). Patients who underwent SILA returned to oral feeding sooner than those who underwent CLA (median 12 h v. 22 h, p < 0.001). These between-group differences remained significant after controlling for other factors. Direct comparison of only nonperforated cases, which was determined by pathological examination, revealed that SILA was significantly longer than CLA (60 min v. 50 min, p < 0.001). Patients who underwent SILA had longer in-hospital stays than those who underwent CLA (72 v. 55 h, p < 0.001); however, they had significantly fewer complications (3.0% v. 14.4%, p = 0.006).Conclusion
In addition to its cosmetic advantages, SILA led to rapid recovery and no increase in postsurgical pain or complications. 相似文献7.

Background
The natural evolution of an acute care surgery (ACS) service is to develop disease-specific care pathways aimed at quality improvement. Our primary goal was to evaluate the implementation of an ACS pathway dedicated to suspected appendicitis on patient flow and the use of computed tomography (CT) in the emergency department (ED).Methods
All adults within a large health care system (3 hospitals) with suspected appendicitis were analyzed during our study period, which included 3 time periods: pre-and postimplementation of the disease-specific pathway and at 12-month follow-up.Results
Of the 1168 consultations for appendicitis that took place during our study period, 349 occurred preimplementation, 392 occurred postimplementation, and 427 were follow-up visits. In all, 877 (75%) patients were admitted to the ACS service. Overall, 83% of patients underwent surgery within 6 hours. The mean wait time from CT request to obtaining the CT scan decreased with pathway implementation at all sites (197 v. 143 min, p < 0.001). This improvement was sustained at 12-month follow-up (131 min, p < 0.001). The pathway increased the number of CTs completed in under 2 hours from 3% to 42% (p < 0.001). No decrease in the total number of CTs or the pattern of ultrasonography was noted (p = 0.42). Wait times from ED triage to surgery were shortened (665 min preimplementation, 633 min postimplementation, 631 min at the 12-month follow-up, p = 0.040).Conclusion
A clinical care pathway dedicated to suspected appendicitis can decrease times to both CT scan and surgical intervention. 相似文献8.
Background
The role of laparoscopy in the setting of perforated appendicitis remains controversial. A retrospective study was conducted to evaluate the early postoperative outcomes of laparoscopic appendectomy (LA) compared to open appendectomy (OA) in patients with perforated appendicitis.Methods
A total of 1,032 patients required an appendectomy between January 2005 and December 2009. Among these patients, 169 presented with perforated appendicitis. Operation times, length of hospital stay, overall complication rates within 30 days, and surgical site infection (SSI) rates were analyzed.Results
Out of the 169 evaluated patients, 106 required LA and 63 OA. Although operation times were similar in both groups (92 ± 31 min for LA vs. 98 ± 45 for OA, p = 0.338), length of hospital stay was shorter in the LA group (6.9 ± 3.8 days vs. 11.5 ± 9.2, p < 0.001). Overall complication rates were significantly lower in the LA group (32.1 vs. 52.4 %, p < 0.001), as were incisional SSI (1.9 vs. 22.2 %, p < 0.001). Organ/space SSI rates were similar in both groups (23.6 % after LA vs. 20.6 % after OA, p = 0.657).Conclusions
For perforated appendicitis, LA results in a significantly shorter hospital stay, fewer overall postoperative complications, and fewer wound infections compared to OA. Organ/space SSI rates were similar for both procedures. LA provides a safe option for treating patients with perforated appendicitis. 相似文献9.
Introduction
The prevailing view on appendicitis is that the main aetiology is obstruction owing to faecoliths in adults and lymphoid hyperplasia in children. Faecoliths on imaging studies are believed to correlate well with appendicitis.Methods
A retrospective chart review was conducted of 1,014 emergency appendicectomy patients between 2001 and 2011. Faecolith prevalence in adult and paediatric appendicectomy specimens with and without perforation was studied. The sensitivity and positive predictive value (PPV) of computed tomography (CT) for identifying faecoliths in the pathology specimen were examined.Results
Overall, faecoliths were found in 18.1% (178/986) of appendicitis specimens and 28.6% (8/28) of negative appendicectomies. Faecolith prevalence for positive cases was 29.9% (79/264) in paediatric patients and 13.7% (99/722) in adults (p<0.05). Faecolith prevalence was 39.4% in perforated appendicitis but only 14.6% in non-perforated appendicitis (p<0.05). In adults, faecolith prevalence was 27.5% in perforated appendicitis and 12.0% in non-perforated appendicitis (p<0.05) while in paediatric patients, it was 56.1% in perforated appendicitis and 22.7% in non-perforated appendicitis (p=0.00). Sensitivity and PPV of preoperative CT in identifying faecoliths on pathology were 53.1% (86/162) and 44.8% (86/192) respectively.Conclusions
Faecolith prevalence is too low to consider the faecolith the most common cause of non-perforated appendicitis. Faecoliths are more prevalent in paediatric appendicitis than in adult appendicitis. Preoperative CT is an unreliable predictor of faecoliths in pathology specimens. 相似文献10.

Background
Although ischemic stroke is a well-known complication of cardiovascular surgery it has not been extensively studied in patients undergoing noncardiac surgery. The aim of this study was to assess the predictors and outcomes of perioperative acute ischemic stroke (PAIS) in patients undergoing noncardiothoracic, nonvascular surgery (NCS).Methods
We prospectively evaluated patients undergoing NCS and enrolled patients older than 18 years who underwent an elective, non-daytime, open surgical procedure. Electrocardiography and cardiac biomarkers were obtained 1 day before surgery, and on postoperative days 1, 3 and 7.Results
Of the 1340 patients undergoing NCS, 31 (2.3%) experienced PAIS. Only age (odds ratio [OR] 2.5, 95% confidence interval [CI] 1.01–3.2, p < 0.001) and preoperative history of stroke (OR 3.6, 95% CI 1.2–4.8, p < 0.001) were independent predictors of PAIS according to multivariate analysis. Patients with PAIS had more cardiovascular (51.6% v. 10.6%, p < 0.001) and noncardiovascular complications (67.7% v. 28.3%, p < 0.001). In-hospital mortality was 19.3% for the PAIS group and 1% for those without PAIS (p < 0.001).Conclusion
Age and preoperative history of stroke were strong risk factors for PAIS in patients undergoing NCS. Patients with PAIS carry an elevated risk of perioperative morbidity and mortality. 相似文献11.

Objective
We conducted a retrospective cohort study to determine whether laparoscopic adrenalectomy (LA) is a safe and effective therapy for the management of pheochromocytoma, as compared with open adrenalectomy (OA).Methods
We collected pertinent data on 47 pheochromocytoma resections from 44 patient charts. Perioperative outcomes of 30 LAs were compared with 14 OAs.Results
Median (and standard deviation [SD]) length of postoperative stay was shorter in the laparoscopic group (3.0, SD 3.3 d v. 6.0, SD 1.1 d; p < 0.05), and tumour size was smaller (3.9, SD 2.7 cm v. 5.0, SD 2.9 cm; p < 0.05). No statistically significant differences were found for operative time or rate of postoperative complications. There were no statistically significant between-group differences in intraoperative hypertensive episodes (systolic blood pressure > 180 and/or diastolic blood pressure > 90) or hypotensive episodes (systolic blood pressure < 100 and/or diastolic blood pressure < 60) or in the need for antihypertensive or vasopressive agents. There were no intraoperative complications related to extremes of blood pressure. There were no perioperative mortalities in this series, nor was there an increased risk of recurrent disease with the laparoscopic technique.Conclusion
LA is safe and effective for the management of pheochromocytoma. 相似文献12.
Objective
Laparoscopic appendectomy (LA) remains controversial in our city, in part because of results obtained early in the learning curve. In 1995, our centre reported that LA took 30 minutes longer and yet resulted in similar length of hospital stay, compared with open appendectomy (OA). The purpose of the current study is to reexamine LA now that more experience has been gained with the procedure and to document the learning curve at a typical Canadian teaching centre.Methods
We undertook a retrospective chart review of patients undergoing nonelective appendectomy between January 2001 and June 2004; this yielded 201 charts that satisfied the inclusion criteria. The 201 cases were divided into 3 groups, each consisting of 67 consecutive cases, to allow for comparison between early, middle and late experience. The main outcomes of interest were operative time, length of stay and the changes over time that occurred in these 2 measures. An intent-to-treat analysis was performed.Results
The mean operative time differed by only minutes: 54.9 (standard error of mean [SEM] 1.9) minutes for LA and 48.8 (SEM 1.4) minutes for OA (p = 0.004). Length of stay was 1.3 (SEM 0.1) days and 2.9 (SEM 0.2) days for LA and OA groups, respectively (p < 0.0001). Analysis of the 3 time periods (early, middle and late) revealed significant improvements in operative time and length of stay for LA in the middle, compared with the early, time periods.Conclusion
These data suggest that, with experience, LA operative time approaches that of OA and length of stay decreases. A shortened hospital stay and similar operative time, along with educational advantages, support the use of the LA in teaching centres. 相似文献13.

Background:
Appendectomy, being the most common surgical procedure performed in general surgery, is still being performed by both open and laparoscopic methods due to a lack of consensus as to which is the most appropriate method. Because further trials are necessary and few such studies have been performed in developing countries, we decided to evaluate the outcomes of the 2 procedures to share our experience with the international community.Methods:
Consecutive patients with suspected acute appendicitis who underwent laparoscopic (LA) (n=48) and open (n=52) appendectomy (OA) over a period of 3 years were studied. Clinical outcomes were compared between the 2 groups in relation to operative time, analgesia used, length of hospital stay, return to work, resumption of a regular diet, and postoperative complications.Results:
Mean age of patients was 25.8 years in the laparoscopic and 25.5 years in the open group. Patient demographics were similar in both groups (P>0.05). There was significantly less need for analgesia (1.0±0.5 in LA and 1.5±0.6 doses in OA), a short hospital stay (1.4±0.7 in LA and 3.4±1.0 days in OA), early return to work (12.6±3.3 in LA and 19.1±3.1 days in OA), and less time needed to return to a regular diet (20.1±2.9 in LA and 22.0±4.7, P<0.05 in OA) in the laparoscopic appendectomy group. Operative time was significantly shorter (54.9±14.7 in LA and 13.6±12.6 minutes in OA) in the open group. Total number of complications was less in the laparoscopic group; however, there was no statistically significant difference.Conclusion:
The laparoscopic technique is a safe and clinically beneficial operative procedure. It provides certain advantages over open appendectomy, including short hospital stay, decreased requirement of postoperative analgesia, early food tolerance, and earlier return to normal activities. Where feasible, laparoscopy should be undertaken as the initial procedure of choice for most cases of suspected appendicitis. 相似文献14.

Background
The increasing incidence of hip fractures in our aging population challenges orthopedic surgeons and hospital administrators to effectively care for these patients. Many patients present to regional hospitals and are transferred to tertiary care centres for surgical management, resulting in long delays to surgery. Providing timely care may improve outcomes, as delay carries an increased risk of morbidity and mortality.Methods
We retrospectively reviewed the cases of all patients with hip fractures treated in a single Level 1 trauma centre in Canada between 2005 and 2012. We compared quality indicators and outcomes between patients transferred from a peripheral hospital and those directly admitted to the trauma centre.Results
Of the 1191 patients retrospectively reviewed, 890 met our inclusion criteria: 175 who were transferred and 715 admitted directly to the trauma centre. Transfer patients’ median delay from admission to operation was 93 hours, whereas nontransfer patients waited 44 hours (p < 0.001). The delay predominantly occurred before transfer, as the patients had to wait for a bed to become available at the trauma centre. The median length of stay in hospital was 20 days for transfer patients compared with 13 days for nontransfer patients (p < 0.001). Regional policy changes enacted in 2011 decreased the median transfer delay from regional hospital to tertiary care centre from 47 to 27 hours (p = 0.005).Conclusion
Policy changes can have a significant impact on patient care. Prioritizing patients and expediting transfer will decrease overall mortality, reduce hospital stay and reduce the cost of hip fracture care. 相似文献15.

INTRODUCTION
No reliably specific marker for acute appendicitis has been identified. Although recent studies have shown hyperbilirubinaemia to be a useful predictor of appendiceal perforation, they did not focus on the value of bilirubin as a marker for acute appendicitis. The aim of this study was to determine the value of hyperbilirubinaemia as a marker for acute appendicitis.MATERIALS AND METHODS
A retrospective analysis of appendicectomies performed in two hospitals (n=472). Data collected included laboratory and histological results. Patients were grouped according to histology findings and comparisons were made between the groups.RESULTS
The mean bilirubin levels were higher for patients with simple appendicitis compared to those with a non-inflamed appendix (p<0.001). More patients with simple appendicitis had hyperbilirubinaemia on admission (30% vs 12%) and the odds of these patients having appendicitis were over three times higher (odds ratio: 3.25, p<0.001). Hyperbilirubinaemia had a specificity of 88% and a positive predictive value of 91% for acute appendicitis. Patients with appendicitis who had a perforated or gangrenous appendix had higher mean bilirubin levels (p=0.01) and were more likely to have hyperbilirubinaemia (p<0.001). The specificity of hyperbilirubinaemia for perforation or gangrene was 70%. The specificities of white cell count and C-reactive protein were less than hyperbilirubinaemia for simple appendicitis (60% and 72%) and perforated or gangrenous appendicitis (19% and 36%).CONCLUSIONS
Hyperbilirubinaemia is a valuable marker for acute appendicitis. Patients with hyperbilirubinaemia are also more likely to have appendiceal perforation or gangrene. Bilirubin should be included in the assessment of patients with suspected appendicitis. 相似文献16.

Introduction
Enhanced recovery is a concept that has become increasingly popular for arthroplasty surgery over the last ten years. This study was designed to assess the analgesia requirements, pain levels and time to discharge for patients having primary arthroplasty in the enhanced recovery pathway.Methods
A multidisciplinary prospective cohort study was carried out between January 2012 and March 2012. Data were collected for patients undergoing primary arthroplasty in one hospital during this time. Details of anaesthesia, local infiltration, additional medications and analgesia were recorded. A visual analogue scale pain score was obtained from each patient at time of mobilisation on days 0, 1, 2 and 3 postoperatively.Results
Ninety-six patients were included in the study. Of these, 34 underwent total hip arthroplasty and 62 total knee arthroplasty (TKA). Pain was the greatest contributor for delayed discharge in TKA patients. The patients who had TKA and did not receive non-steroidal anti-inflammatory drugs (NSAIDs) had significantly higher pain scores (day 0, p<0.01; day 1, p<0.001; day 2, p<0.01) and significantly increased opiate demands compared with those patients who did receive NSAIDs.Conclusions
There are unacceptably high pain scores in patients undergoing TKA without the use of NSAIDs. There should be focused intervention with this group of patients to improve their pain scores and reduce their length of stay. 相似文献17.

Objective
To test the hypothesis that complication rates for elective total hip replacement operations are related to surgeon and hospital volumes.Design
Retrospective population cohort study.Study cohort
Patients who had undergone elective total hip replacement in Ontario during 1992 as captured in the Canadian Institute for Health Information database.Main outcome measures
In-hospital complications, 1- and 3-year revision rates, 1- and 3-year infection rates, length of hospital stay, and 3-month and 1-year death rates.Results
Surgeons with patient volumes above the 80th percentile (more than 27 hip replacements annually) discharged patients approximately 2.4 days earlier (p < 0.05) than surgeons with volumes below the 40th percentile (less than 9 hip replacements annually) even after adjusting for discharge disposition, hospital volume, patient age, sex, comorbidity and diagnosis. Complication rates requiring hospital readmission and death rates did not differ by surgeon or hospital volume (p > 0.05).Conclusions
There is no evidence to support regionalization of elective hip replacement surgery in Ontario based on adverse clinical outcomes. Surgeons who perform a large number of total hip replacements are discharging patients earlier than less experienced surgeons, without any demonstrable increase in complications leading to hospital readmission. The explanation for this observation remains unknown and will require further study. 相似文献18.

Background
Patients with neuromuscular disorders often have an increased risk of pneumonia and decreased lung function, which may further be compromised by scoliosis. Scoliosis surgery may improve pulmonary function in otherwise healthy patients, but no study has evaluated its effect on the risk of pneumonia in patients with neuromuscular scoliosis (NMS).Methods
The patient charts of 42 patients (mean age 14.6 years) who had undergone surgery for severe NMS (mean scoliosis 86°) were retrospectively reviewed from birth to a mean of 6.1 years (range 2.8–9.5) after scoliosis surgery. The main outcome was radiographically confirmed pneumonia as a primary cause for hospitalization. We excluded postoperative (3 months) pneumonia from the analyses.Results
The lifetime annual incidence of pneumonia was 8.0/100 before and 13.4/100 after scoliosis surgery (p > 0.10). The mean number of hospital days per year due to pneumonia were 0.59 (SD 2.3) before scoliosis surgery and 2.24 (SD 6.9) after surgery (p > 0.10). Multivariate analysis demonstrated that lifetime risk factors for pneumonia were epilepsy (RR 15.2, 95 % CI 1.3–176.8, p = 0.027), non-cerebral palsy (CP) etiology (RR = 10.2, 95 % CI 3.2–32.7, p < 0.001) and major scoliosis (main curve >70°; RR = 11.3, 95 % CI 1.8–70.7, p = 0.01).Conclusions
Epilepsy, non-CP etiology and major scoliosis are significant risk factors for pneumonia in patients with NMS. Scoliosis surgery does not decrease the incidence of pneumonia in patients with severe NMS.Level of Evidence

Background
Clinical evaluation alone is still considered adequate by many clinicians who treat patients with appendicitis. The impact of computed tomography (CT) on clinical outcomes remains unclear, and there is no consensus regarding the appropriate use of CT in these patients. We sought to evaluate the impact of abdominal CT on the clinical outcomes of patients presenting with suspected appendicitis.Methods
We conducted a systematic review of the literature to identify studies that examined clinical outcomes related to the use of abdominal CT in the diagnosis of acute appendicitis. Inclusion criteria were studies of adult patients with suspected appendicitis that evaluated the impact of abdominal CT on negative appendectomy rates, perforation rates or time to surgery. Two independent investigators reviewed all titles and abstracts and extracted data from 28 full-text articles. Statistical analysis was conducted using Review Manager 5.0.10 software.Results
The negative appendectomy rate was 8.7% when using CT compared with 16.7% when using clinical evaluation alone (p < 0.001). There was also a significantly lower negative appendectomy rate during the CT era compared with the pre-CT era (10.0% v. 21.5%, p < 0.001). Time to surgery was evaluated in 10 of the 28 studies, 5 of which demonstrated a significant increase in the time to surgery with the use of CT. Appendiceal perforation rates were unchanged by the use of CT (23.4% in the CT group v. 16.7% in the clinical evaluation group, p = 0.15). Similarly, the perforation rate during the CT era was not significantly different than that during the pre-CT era (20.0% v. 19.6%, p = 0.74).Conclusion
This meta-analysis supports the hypothesis that the use of preoperative abdominal CT is associated with lower negative appendectomy rates. The use of CT in the absence of an expedited imaging protocol may delay surgery, but this delay is not associated with increased appendiceal perforation rates. Routine CT in all patients presenting with suspected appendicitis could reduce the rate of unnecessary surgery without increasing morbidity. 相似文献20.
