Background

Acute appendicitis continues to be a condition at high risk for missed and delayed diagnosis. It characteristically presents with right lower quadrant pain after vague epigastric or periumbilical discomfort. Left-sided appendicitis is an atypical presentation and has been reported rarely. The majority of these cases have been described to be associated with congenital midgut malrotation, situs inversus, or an extremely long appendix. We report a case of left-sided acute appendicitis occurring in a patient with a redundant and hypermobile ascending colon.

Objectives

To alert emergency physicians to an anatomical anomaly that could delay the diagnosis of appendicitis.

Case Report

A 50-year-old man presented with fever and left lower abdominal pain. Physical examination revealed local tenderness over the left lower quadrant. Abdominal computed tomography scan revealed a redundant, floating, ascending colon and inflammatory appendix adhering to the descending colon over the left lower abdomen. Exploratory laparotomy was performed and perforated appendicitis with turbid ascites was found during the surgery. Appendectomy was performed and the patient recovered uneventfully.

Conclusion

This case is presented to increase awareness among emergency physicians of this anatomical variant and atypical presentation of appendicitis.  相似文献

Background

We report a case of an atypical presentation of acute appendicitis in an adult due to an undiagnosed congenital gut malrotation.

Objective

The obvious benefit of observation with serial examinations followed by the use of computed tomography (CT) is discussed in aiding in the diagnosis for atypical presentations of appendicitis.

Case Report

A 45-year-old man who presented with epigastric pain and vomiting was diagnosed with acute left-sided appendicitis on CT scan. The patient’s appendix was located in the left lower quadrant of the abdomen due to undiagnosed congenital gut malrotation, thus resulting in an atypical presentation of a common illness.

Conclusion

Observation with serial examinations, followed by CT scanning if indicated, is an invaluable strategy to use in diagnosing atypical presentations of common pathology.  相似文献

Background

Hyperpyrexia associated with right iliac fossa pain and tenderness in a young patient is a common finding in an Emergency Department, and is frequently caused by acute appendicitis or genitourinary affliction. Especially in the case of young males, it is debated whether the patient should undergo immediate surgery or be referred for imagery, and, when surgery is finally planned, whether an open incision of the iliac fossa or a laparoscopic approach is preferred.

Objective

We describe a case of a patient with a twisted, ischemic ileal hemangioma mimicking an acute appendicitis, which was diagnosed and managed laparoscopically.

Case Report

A 16-year-old boy was admitted to the Emergency Department with a 2-day history of hyperpyrexia, nausea, right iliac fossa pain, and tenderness. Perioperative computed tomography scan showed a 3-cm image that was interpreted as a periappendicular abscess. At laparoscopy, a twisted ischemic mass adherent to the surrounding ileum was located and removed. The patient’s outcome was uneventful. Pathology showed a benign hemangioma of the ileal mesentery. To our knowledge, this is the first case treated by laparoscopic resection.

Conclusions

Rare conditions, such as peduncolated tumors, can mimic common conditions like acute appencitis. Also, due to the aspecificity of symptoms and difficult interpretation of imagery, diagnosis can be difficult to achieve preoperatively and surgery can be challenging. Laparoscopy can allow a diagnosis to be made and the appropriate treatment to be performed without the need for laparotomy. Rare causes of appendicitis-like syndrome represent an argument in favor of a laparoscopic approach, even in the case of young male patients.  相似文献

Background

Acute appendicitis is a common disease process in which timely diagnosis minimizes the risk of complications.

Objectives

This case illustrates one example of the range of clinical presentations of young children with acute appendicitis.

Case Report

We describe a case in a young child presenting with an inguinal and scrotal mass that was ultimately due to perforated appendicitis with abscess formation.

Conclusions

In the emergency department evaluation of these children with inguinal or scrotal complaints, we maintain that intra-abdominal processes should be included in the differential.  相似文献

Background

Diverticulosis and diverticulitis of appendix vermiformis is a rare diagnosis. Clinical and laboratory examinations do not show a difference between a progressing diverticulitis and simplex appendicitis. But this entity has a higher mortality rate than common appendicitis.

Objective

This case is presented to illustrate the point that preoperative simple diagnosis of acute appendicitis according to the clinical signs and physical examination may not only be insufficient, but could be fatal in certain circumstances, like appendiceal diverticulitis, if surgical intervention is delayed.

Case Report

Here we present a female patient with a history of right lower abdominal pain and fever of 3 days duration. She was diagnosed with acute appendicitis according to the preoperative physical, laboratory, and imaging examinations. The appendiceal diverticulitis accompanying acute appendicitis was an intraoperative finding, which was proven by histopathologic examination.

Conclusion

It is not easy to document this entity preoperatively. When diagnosed either preoperatively by imaging studies or intraoperatively, the only choice is appendectomy to prevent its serious complications.  相似文献

Background

Computed tomography (CT) has been used in diagnosing acute appendicitis since late 1990s. Appropriate use of CT has not been studied prospectively in patients with suspected acute appendicitis and relative low Alvarado score.

Methods

Sixty participants with suspected acute appendicitis and an Alvarado score of 4 to 7 points were enrolled for analysis. Clinical and laboratory differences were compared between patients with histologically proven acute appendicitis (AA group) and patients without evidence of acute appendicitis (non-AA group) in the first part of the analysis. In the second part of the analysis, participants were divided into 2 groups: leukocytosis (LK group) and nonleukocytosis (non-LK group).

Results

In the first phase of the analysis, there were statistically significant differences in white blood cell count (13.5 K vs 10.9 K per μL), neutrophilia (81.5% vs 73.5%), and hospital stay (4.9 vs 3.5 days) between the 2 groups. Disease spectrum between LK and non-LK groups was obtained in second part of analysis.

Conclusion

Computed tomography scan is necessary for patients with relatively low Alvarado score when leukocytosis is noted. In female patients without leukocytosis, further large-scale prospective studies are necessary to change the current diagnostic strategy.  相似文献

Objective

Acute appendicitis is the most common abdominal emergency in children and young adults. There are a lot of serotonin-containing cells in the appendix, which release serotonin into the bloodstream in response to inflammation. Consequently, serotonin is converted to 5-hydroxyindoleacetic acid (5-HIAA) and secreted into the urine. On this basis, urinary 5-HIAA could be a marker for acute appendicitis. In this study, we investigated the value of 5-HIAA levels in spot urine in the diagnosis of acute appendicitis.

Methods

The urinary 5-HIAA was measured by an enzyme-linked immunosorbent assay in the spot urine of 70 patients who presented to the emergency department with a clinical picture of acute appendicitis. Urine concentration results were correlated to final histopathologic reports, and the diagnostic value of this factor was measured.

Results

Diagnosis of appendicitis was confirmed by histopathologic reports in 59 of 70 patients with presumptive diagnosis of appendicitis. Considering 5.25 mg/L as the cutoff point for urinary 5-HIAA, 28 patients had high urinary 5-HIAA levels, whereas 42 patients had values within reference range. The sensitivity and specificity of this test was 44% and 81%, respectively.

Conclusions

The measurement of urinary 5-HIAA levels is not an ideal diagnostic tool for ruling out or determination of acute appendicitis.  相似文献

Background

To improve the diagnostic accuracy of identifying acute appendicitis, imaging modalities, such as ultrasound and the computed tomography scan, are used in combination with the history and physical examination. There is no reliable single laboratory marker to assist with this diagnosis. During inflammation, enterochromaffin cells in the appendix secrete serotonin, and 5-hydroxyindoleacetic acid (5-HIAA), a serotonin metabolite excreted in urine, has been found to be elevated in patients presenting with acute appendicitis.

Objective

The aim of this study was to measure the urinary 5-HIAA concentrations of patients presenting with symptoms of acute appendicitis to determine the sensitivity and specificity of urinary 5-HIAA levels for diagnosing acute appendicitis.

Methods

5-HIAA was quantitatively measured by high-performance liquid chromatography in the spot urine of 100 healthy individuals, aged 18 to 70 years, who presented to the emergency medicine department with a clinical picture of acute appendicitis. Urine concentration results were correlated to the gold standard of histopathologic reports of removed appendices. The sensitivity, specificity, and their 95% confidence intervals were derived.

Results

Of the 100 patients presenting with symptoms consistent with acute appendicitis, 72 had appendectomies and 2 had cholecystectomies. The remaining 26 patients were discharged after hospital observation. A total of 64 patients were found to have appendicitis: 52 had acute appendicitis, whereas 12 had perforated and/or gangrenous (nonacute) appendices. The acute appendicitis group had a mean urinary 5-HIAA level of 19.31 μmol/L, slightly lower than the 23.10 μmol/L of the patients with gangrenous/perforated appendicitis. The group without appendicitis had a urinary 5-HIAA value of 17.27 μmol/L. Using the lowest of previously reported cutoffs, we calculated the sensitivity and specificity of this test for acute appendicitis as 63% and 33%, respectively.

Conclusion

Urinary 5-HIAA level is not a good diagnostic tool for determining acute appendicitis.  相似文献

Background

Aggressive behavior and violence directed by patients at nurses are increasing worldwide. Aggressive behavior against nurses in their workplace can result in personal problems, such as impairment of physical and mental well-being, and, consequently, in organizational problems. Underreporting of patients’ aggressive behavior is prevalent among nurses. Although underreporting might lead to inefficient attention to strategies for preventing aggressive behavior, the reasons for such behavior not being reported frequently have not been well examined.

Objectives

To explore the frequency of nurses’ reporting to their managers of patients’ aggressive behavior by type and degree of impact suffered by the nurses, to examine the association between reporting of aggressive behavior and demographic factors, and to determine the reasons for underreporting.

Design

A questionnaire-based cross-sectional survey.

Setting

Six acute care hospitals in two regions in Japan.

Participants

A total of 1953 nurses working at general acute care hospitals participated.

Methods

Data were collected through a questionnaire seeking sociodemographic information, information on experience of aggressive behavior from patients, and the frequency with which they had reported such behavior in the previous month. The questionnaire also contained items assessing barriers to reporting of patients’ aggressive behavior. The association between the possible influencing factors and reporting behavior was assessed using multiple logistic regression analyses.

Results

Of the 1953 questionnaires distributed, 1498 (76.7%) were returned, and 1385 (70.9%) fully completed questionnaires were analyzed. More than one-third of the respondents had experienced the mildest assessed level of impact from patients’ aggressive behavior, and 70% of those hardly reported any incidents. The milder the impact was, the less the nurse victims tended to report the incident. Nurse's tendency to feel that aggressive behavior was mitigated by the situation, less work experience, and lack of confidence that management would defend staff nurses from patients’ aggressive behavior were found to be negatively associated with reporting behavior.

Conclusions

This study identified factors associated with nurses’ reporting of patients’ aggressive behavior. Underreporting was found to be associated with the level of impact, managerial attitudes, nurses’ work experience, and nurses’ perception that the behavior was mitigated by the situation. Improving education among nurses to promote reporting incidents and establishing an organized system is needed.  相似文献

Background

Both ectopic pregnancy and appendicitis are surgical emergencies that should be considered in female patients who present with right lower-quadrant pain. Deciding on the appropriate imaging modality in the pregnant patient can be difficult. The challenge of diagnosis is compounded when one considers that both pathologies may be present simultaneously.

Objectives

We present a case demonstrating co-occurrence of ectopic pregnancy and appendicitis and suggest an algorithm for evaluation and management of cases with this presentation.

Case Report

A 25-year-old woman presented to the Emergency Department complaining of 3 days of abdominal pain and a positive urine pregnancy test. After consultation with Obstetrics/Gynecology (OB/GYN) and General Surgery, a nondiagnostic pelvic ultrasound (US), and a magnetic resonance imaging (MRI) study consistent with appendiceal inflammation, the patient was taken to the operating room for a laparoscopic appendectomy. While removing the inflamed appendix, the general surgeon noted the right fallopian tube was enlarged, suggestive of an ectopic pregnancy. OB/GYN was consulted again intraoperatively and noted a right ectopic pregnancy. The surgical intervention was completed with a right salpingectomy.

Conclusion

In a pregnant patient with right lower-quadrant pain, the differential diagnosis includes ectopic pregnancy, acute appendicitis, or in rare cases, both.  相似文献

Background

Phytobezoar-induced small bowel obstruction is an uncommon clinical entity accounting for 2–4.8% of all mechanical intestinal obstructions. In addition, presentation with features of acute surgical abdomen is extremely rare, accounting for only 1% of the patients.

Objectives

The aim of this report is to present a very rare case of a phytobezoar-induced small bowel obstruction in a male patient who presented with acute surgical abdomen. A correct preoperative diagnosis was made based on the patient’s history and characteristic imaging features on the emergency computed tomography (CT) scan.

Case Report

A 55-year-old man with previous gastrectomy presented with typical manifestations of acute abdomen. CT scan demonstrated dilatated small bowel loops and an intraluminal ileal mass with a mottled appearance. At exploratory laparotomy, a phytobezoar was found impacted in the terminal ileum and was removed through an enterotomy.

Conclusions

Phytobezoar should be considered in patients with previous gastric outlet surgery who present with bowel obstruction and features of acute surgical abdomen. The presence of a well-defined intraluminal mass with a mottled gas pattern on emergency CT scan is suggestive of an intestinal phytobezoar.  相似文献

Study Objective

There has been no clear-cut value of the white blood cell (WBC) count in differential diagnosis of acute appendicitis in emergency medicine. Therefore, the aim of this study was to assess the preoperative WBC counts in 3 groups of patients operated on for a clinical suspicion of acute appendicitis with different findings at appendectomy: uninflamed appendix, uncomplicated acute appendicitis, or complicated acute appendicitis.

Methods

The medical records of 540 patients who underwent appendectomy for suspected acute appendicitis during a 17-month period were retrospectively reviewed. Data for 3 groups of patients were analyzed to calculate the sensitivity and specificity of the WBC count in the diagnosis of acute appendicitis, and we calculated likelihood ratios for 2 cut-points with either high sensitivity or high specificity. Receiver operating characteristic curves were used to evaluate the WBC count in relation to the true diagnosis and severity of acute appendicitis.

Results

We were able to identify patients with appendicitis on a statistically significant level using receiver operating characteristic curves of WBC counts (area under the curve = 0.756, P < .001), but the WBC count had no diagnostic value in differentiating between uncomplicated and complicated groups (area under the curve =0.55, P = .086). Likelihood ratio ranged from 1.79 (95% confidence interval, 1.17-2.3) for WBC count of more than 10 500 cells/mm3 to 3.20 (95% confidence interval, 2.72-3.24) for WBC count of more than 14 300 cells/mm3.

Conclusion

White blood cell count is helpful in the diagnosis and exclusion of appendicitis. However, there is no value to differentiate advanced appendicitis.  相似文献

Background

Bilateral vocal cord paralysis can produce severe airway obstruction, leading to acute respiratory failure. Discriminating the pathology of the upper airway from chronic obstructive diseases of the lower airways often presents a challenge for clinicians in the Emergency Department.

Objectives

To underlie the value of clinical examination and flow-volume loops in the establishment of diagnosis of upper airway obstruction.

Case Report

We describe the case of a 55-year-old female ex-smoker who presented with a long history of hoarseness and progressive exertional dyspnea. The patient developed repeated episodes of acute respiratory failure and was supported with noninvasive ventilation. The diagnosis of bilateral vocal cord paralysis was finally established by patient’s symptoms and flow-volume loops demonstrating variable extrathoracic obstruction.

Conclusion

Vocal cord paralysis is a rare and often neglected condition, contributing to repeated episodes of acute respiratory failure. Flow-volume loop is a useful tool when symptoms are suggestive of upper airway obstruction.  相似文献

Background

Right-sided diverticulitis is a rare source of right lower quadrant pain in Western society; however, it is quite common in Asian societies. Right-sided diverticulitis presents very similarly to appendicitis, with right lower quadrant pain, fever, nausea, and laboratory abnormalities, and is often seen in young patients.

Objectives

In this report, we present a case of right-sided diverticulitis. We review right-sided diverticulitis’ diagnosis and management. It is important to diagnose right-sided diverticulitis because it is a good mimic of appendicitis and ideally should be diagnosed before a patient has unnecessary surgery.

Case Report

A 26-year-old Asian woman presented for evaluation of right lower quadrant pain and fever. She was initially thought to have appendicitis clinically, but had right-sided diverticulitis diagnosed by computed tomography (CT) scan. She was admitted and received intravenous antibiotics and bowel rest. Her right-sided diverticulitis resolved in 3 days.

Conclusions

Severe right lower quadrant pain in young patients of Asian descent can be right-sided diverticulitis. Right-sided diverticulitis is a benign condition managed medically that mimics appendicitis. CT imaging seems to be the best way to avoid unnecessary surgery.  相似文献

Purpose

Acute appendicitis is one of the most common surgical emergencies. Diagnosis is usually made depending on the presenting history, clinical evaluation, and laboratory tests. The aim of this study was to investigate the role of urinary 5-hydroxyindoleacetic acid (U-5-HIAA) in the early diagnosis of acute appendicitis.

Methods

Thirty-five pigmented male rabbits were divided into 5 groups. Group 1 is the control (n = 7); group 2 is the sham (n = 10). The appendix was ligated from its base, and an appendectomy was performed after 12, 24, 36 hours in group 3 (n = 7), group 4 (n = 7), and group 5 (n = 7), respectively. Spot urine samples were obtained for U-5-HIAA determination, and appendectomy tissues were examined histopathologically.

Results

Acute appendicitis was diagnosed in all animals in group 3, group 4, and group 5, and the mean levels of U-5-HIAA in group 3 were higher than in the other groups. The mean of U-5-HIAA levels between animals with appendicitis and those without showed a significant difference (P = .003). The U-5-HIAA cutoff point of 4.15 mg/g creatinine had a sensitivity of 85%, a specificity of 64.29%, and an accuracy of 76% (area under curve = 0.805) for acute appendicitis. The probability of acute appendicitis is found to be 10, 2 times more when the U-5-HIAA level is greater than 4.15 mg/g creatinine.

Conclusion

We have concluded that spot U-5-HIAA level increases significantly in the early stages of acute appendicitis.  相似文献

Background

The importance of transformational leadership for nurses’ well-being is increasingly acknowledged. However, there is a paucity of research examining the mechanisms that may explain the relationships between transformational leadership and nurses’ quality of work life.

Objectives

First, to examine two possible psychological mechanisms that link transformational leadership behaviors to nurses’ quality of work life. Second, to study the relationship between nurses’ quality of work life and their work engagement.

Design

Cross-sectional study design.

Settings

The study took place in 47 different hematology, oncology, and hematology/oncology units in France. Participants were nurses and auxiliary nurses.

Participants

343 nurses completed the questionnaire. Surveys were sent to all nurses working in the units. 95% were female, the average age was 36.30 years.

Methods

Nurses were asked to rate their supervisor's transformational leadership style and their perceptions of distributive and interactional justice in the unit. They were also asked to evaluate their own level of quality of work life and their work engagement.

Results

Distributive justice and interactional justice were found to fully mediate the relationship between transformational leadership and nurses’ quality of work life. In addition, nurses’ quality of work life positively related to their work engagement.

Conclusions

Transformational leaders may help ensure nurses’ quality of work life which in turn increases their work engagement. These leadership practices are thus beneficial for both employees and organization.  相似文献

Objective

We aimed to develop a clinical prediction rule to distinguish pelvic inflammatory disease (PID) from acute appendicitis in women of childbearing age.

Methods

We reviewed medical records over a 4-year period of female patients of childbearing age who had presented with abdominal pain at an urban emergency department and had either appendicitis (n = 109) or PID (n = 72). A prediction rule was developed by use of recursive partitioning based on significant factors for the discrimination.

Results

The significant factors to favor PID over appendicitis were (1) no migration of pain (odds ratio [OR], 4.2; 95% confidence interval [CI], 1.5-11.5), (2) bilateral abdominal tenderness (OR, 16.7; 95% CI, 5.3-50.0), and (3) absence of nausea and vomiting (OR, 8.4; 95% CI, 2.8-24.8). The prediction rule could rule out appendicitis from PID with sensitivity of 99% (95% CI, 94-100%) when classified as a low-risk group by the following factors: (1) no migration of pain, (2) bilateral abdominal tenderness, and (3) no nausea and vomiting.

Conclusion

We developed a prediction rule for childbearing-aged women presenting with acute abdominal pain to distinguish acute appendicitis from PID based on 3 simple, clinical features: migration of pain, bilateral abdominal tenderness, and nausea and vomiting. Prospective validation is needed in other settings.  相似文献

Background

The evaluation of patients with pelvic pain is a common task for emergency physicians. Accurate diagnosis of the underlying cause of pelvic pain in women is often difficult given the diversity of pathology that can generate pelvic pain.

Objective

To report a rare but clinically significant cause of acute pelvic pain in women.

Case Report

We describe a rare case of a periurethral abscess secondary to an infected urethral diverticulum in a 41-year-old woman. She presented to our Emergency Department with pelvic pain, dysuria, and fever of 4 days duration.

Conclusion

Physical examination, imaging studies, and surgery aided in confirming the diagnosis of a periurethral abscess.  相似文献

Background

The digital rectal examination (DRE) has been reflexively performed to evaluate common chief complaints in the Emergency Department without knowing its true utility in diagnosis.

Objective

Medical literature databases were searched for the most relevant articles pertaining to: the utility of the DRE in evaluating abdominal pain and acute appendicitis, the false-positive rate of fecal occult blood tests (FOBT) from stool obtained by DRE or spontaneous passage, and the correlation between DRE and anal manometry in determining anal tone.

Discussion

Sixteen articles met our inclusion criteria; there were two for abdominal pain, five for appendicitis, six for anal tone, and three for fecal occult blood. The DRE was shown to add no additional diagnostic information and confounded the diagnosis in acute, undifferentiated abdominal pain. The sensitivity, specificity, positive predictive value, negative predictive value, and odds ratio for the DRE were too low to reliably diagnose acute appendicitis in children and adults. No statistical differences in the number of colonic pathologies were found between stool collection methods in those with positive FOBT. The DRE correlation with anal manometry in determining resting and squeeze anal tone ranged from 0.405 to 0.82 and 0.52 to 0.97, respectively.

Conclusion

We found the DRE to have a limited role in the diagnosis of acute, undifferentiated abdominal pain and acute appendicitis. Stool obtained by DRE doesn't seem to increase the false-positive rate of FOBTs, and the DRE correlated moderately well with anal manometric measurements in determining anal sphincter tone.  相似文献

Purpose

The purpose of this study is to test whether maternal deceased organ donation is associated with rates of subsequent acute injuries among surviving children after their mother’s death.

Methods

This is alongitudinal cohort analysis of children linked to mothers who died of a catastrophic brain event in Ontario, Canada, between April 1988 and March 2012. Surviving children were distinguished by whether their mother was an organ donor after death. The primary outcome was an acute injury event in surviving children during the year after their mother’s death.

Results

Surviving children (n = 454) had a total of 293 injury events during the year after their mother’s death, equivalent to an average of 65 events per 100 children per year and a significant difference comparing children of mothers who were organ donors to children of mothers who were not organ donors (21 vs 82, P < .001). This difference in subsequent injury rates between groups was equal to a 76% relative reduction in risk (95% confidence interval, 62%-85%).

Conclusions

Deceased organ donation was associated with a reduction in excess acute injuries among surviving children after their mother’s death. An awareness of this positive association provides some reassurance about deceased organ donation programs.  相似文献
