RESUMO

Previous studies have suggested that patients with psychotic or mental disorders are relatively pain insensitive, resulting in difficulties in the diagnosis of acute intra-abdominal diseases requiring emergency surgeries. We aimed to evaluate whether central nervous system (CNS) or mental disorders are associated with perforated appendicitis in patients with acute appendicitis.We conducted a population-based case-control study using Taiwan's National Health Insurance Research database. Patients aged >18 years who had been hospitalized with a diagnosis of acute appendicitis between 2000 and 2013 were identified. After 1:1 matching for age and sex, 2792 patients with perforated appendicitis (case group) and 2792 patients with nonperforated appendicitis (control group) were included. CNS disorders, mental disorders, pain control medication, and several comorbidities were analyzed for the odds of appendiceal perforation with 95% confidence interval (CI) using the multivariable logistic regression model.Schizophrenia and dementia were associated with a high risk of appendiceal rupture in patients with acute appendicitis, with an adjusted odds ratio of 2.01 for dementia (95% CI: 1.19-3.39, P = .009) and 4.8 for schizophrenia (95% CI: 1.62-14.19, P = .005). Other factors, such as other CNS disorders, comorbidities, and pain control medication, were not associated with the risk of perforated appendicitis.Dementia and schizophrenia are associated with perforated appendicitis in patients with acute appendicitis. This might be owing to altered pain perception, difficult symptom expression, and delayed hospitalization. Further studies are still needed to determine the underlying mechanism and confirm the causality.

RESUMO

OBJECTIVE: This article stresses an impact of appropriate management work up in the diagnosis of acute apendicitis in puerperium. Atypical clinical symptoms may cause doubts in diagnosis and may delay necessary surgical intervention. DESIGN: Case report. SETTINGS: Department of Gynecology and Obstetrics, 1st Faculty of Medicine, Charles University, and Hospital Na Bulovce, Prague. METHODS: We present a case report describing an atypical presentation of acute apendicitis in early puerperium. Due to atypical course of the disease and atypical imaging locality and morphology, there were doubts about the diagnosis of acute apendicitis, patient was treated conservativelly and the disease later resulted in extensive surgical intervention. CONCLUSION: Acute appendicitis is the most common cause of non-urogenital morbidity in puerperium. Management of work up and timing of surgical intervention have key impact on maternal mortality and morbidity.

RESUMO

BACKGROUND: There currently exists no substantial evidence reporting the efficacy of peritoneal irrigation in reducing the incidence of postoperative intra-abdominal abscess in pediatric patients. The purpose of our study was to perform a meta-analysis to compare rates of intra-abdominal abscess after appendectomy between irrigation and suction alone groups. METHODS: We identified studies by a systematic search in EMBASE, PubMed, Web of Science, and the Cochrane Library to recognize randomized controlled trials and case control studies from the 1950 to May 2019. We limited the English language studies. We checked the reference list of studies to recognize other potentially qualified trials. We analyzed the merged data with use of the Review Manager 5.3. RESULTS: We identified 6 eligible papers enrolling a total of 1633 participants. We found no significant difference in the incidence of postoperative intraabdominal abscess, wound infection, and the length of hospitalization between 2 group, but duration of surgery is longer in irrigation group (MD = 6.76, 95% CI = 4.64 to 8.87, P < .001; heterogeneity, I = 25%, P = .26). CONCLUSION: Our meta-analysis did not provide strong evidence allowing definite conclusions to be drawn, but suggested that peritoneal irrigation during appendectomy did not decrease the incidence of postoperative IAA. This meta-analysis also indicated the need for more high-quality trials to identify methods to decrease the incidence of postoperative IAA in pediatric perforated appendicitis patients.Trial registration number Standardization of endoscopic treatment of acute abdomen in children: 14RCGFSY00150.

RESUMO

Prompt appendectomy has long been the standard of care for acute appendicitis because of the risk of progression to perforation. Recently, studies have suggested nonemergent management of acute appendicitis. Our study aimed to determine changes in risk of rupture and complications in patients with appendicitis, with increasing time from symptom onset to treatment. Retrospective study of patients aged ≥18 years presenting to the University of North Carolina Hospitals with signs and symptoms of acute appendicitis who subsequently underwent appendectomy from 2011 to 2015 was performed. Demographic, clinical, laboratory, and pathologic data were reviewed. Bivariate analysis was performed to assess variables associated with increased risk of perforation. Poisson regression modeling was completed to evaluate the risk of perforation and postoperative abscess based on time from symptoms to treatment. Within our database of 1007 patients, the mean time from onset of symptoms to operative intervention was 3.24 ± 2.2 days. Modified Poisson regression modeling demonstrated the relative risk for perforation increases by 9% (RR 1.09, P < 0.001) for each day delay. Age (RR 1.03), male gender (RR 1.50), temperature on admission (RR 1.32), and the presence of fecalith (RR 1.89) statistically significantly increased the risk of perforation. Furthermore, for each day delay, there is an 8% increased risk of postoperative abscess (RR 1.08, P = 0.027). The relative risk for appendiceal perforation is 9 per cent per day delay with a resultant 8 per cent increased risk of postoperative abscess. Thus, appendectomy for acute appendicitis should remain an emergent procedure, given that delays in operative management lead to complications and increases in cost of care.

RESUMO

INTRODUCTION: Appendectomy is one of the most common emergency surgical operations. Stump appendicitis is a rare complication after appendectomy and is caused by acute inflammation of the remnant part of the appendix. Because of the low index of suspicion owing to a previous history of appendectomy, the diagnosis of stump appendicitis is often delayed. METHODS: Between January 2008 and December 2017, 6 patients were diagnosed with stump appendicitis with or without perforation at a single institution. They had undergone operative management with laparoscopic approach. The clinical data of these patients were retrospectively analyzed by reviewing the medical records and pathologic reports. RESULTS: Five patients were male, with a mean age of 42.4 years (range 11-77 years). The time interval after initial appendectomy ranged from 2 weeks to 30 years. Three patients underwent laparoscopic completion appendectomy, and the others underwent laparoscopic ileocecectomy. The mean hospital stay was 9 days (range 5-13 days). There were no cases of open conversion. CONCLUSIONS: Stump appendicitis is a rare complication after appendectomy. A laparoscopic procedure can be performed for management of stump appendicitis with or without perforation.

RESUMO

BACKGROUND: The laparoscopic appendectomy approach (LAA) for acute appendicitis has fewer intra- and post-operative complications, less pain, and smaller scars compared to the traditional open appendectomy approach (OAA), but a higher frequency of intra-abdominal abscess (IAA). The relationship between this higher frequency of IAA and the omission of appendicular stump invagination is difficult to explain, even though such invagination of the appendicular stump is the only difference between standard LAA and OAA.

RESUMO

BACKGROUND: Stump appendicitis is a rare delayed complication post-appendectomy and it represents a diagnostic problem as clinicians are often not very familiar with this pathology. MATERIALS AND METHODS: One case of stump appendicitis has been reported in a 54 year old woman, whose acute phase was conservatively treated in our Department. A review of Medline literature was also carried out, from 1945 to 2015, showing 111 cases of stump appendicitis. RESULTS: Stump appendicitis has been reported after either open or laparoscopic appendectomy, in a range between days to several years from the first procedure. Nowadays, it is not considered yet as a possible differential diagnosis in patients with pain in the right iliac fossa previously undergone appendectomy. For this reason, the diagnosis can be delayed and complications such as acute abdomen, perforation, sepsis can occur. Completion appendectomy is the treatment of choice for stump appendicitis. CONCLUSIONS: The aim of this article is to underline the importance of stump appendicitis. Clinicians should be aware of the possibility of SA and they should confirm any clinical suspicion throughout radiologic images, in order to promptly recognize this entity and to avoid the related complications.

RESUMO

Femoral hernia strangulation is usually observed in middle-aged women. There are few case reports of appendix strangulation in the femoral hernia. Acute appendicitis in a strangulated femoral hernia is relatively rare (0.4% of cases). Clinical case of acute destructive appendicitis within a strangulated femoral hernia in an elderly woman is reported in the article. If there is doubt about the urgency of surgical intervention, surgeon needs to take a proactive stance and lean toward emergency surgery. Surgeon should be aware of possible strangulation-associated destructive appendicitis due to injury of the appendix.

RESUMO

Using a practical scoring system for diagnosing acute appendicitis can help reduce the rate of unnecessary surgery. This prospective study was carried out to evaluate Alvarado scoring system for diagnosing of acute appendicitis in our set up. Out of total 100 patients, appendicitis was confirmed in 80 patients, thus giving negative appendectomy rate of 20% (male 6%, female 14%). Perforation rate was 4%. Positive predictive value was 89%. The sensitivity was 54% and specificity 75%. Alvarado score is not a sensitive tool for aiding diagnosis of acute appendicitis.

RESUMO

RATIONALE: Mesenteric venous thrombosis is an uncommon but potentially fatal condition that can cause bowel ischemia. It results from a systemic hypercoagulable state or abdominal infection draining into the portal venous system. Several cases regarding portomesenteric venous thrombosis as a complication of appendicitis were reported in adults, but there are far fewer reports in pediatric patients. The mortality rate of the condition is high if untreated, especially in children, reaching up to 50%. PATIENT CONCERNS: A healthy 15-year-old male with no significant past medical history presented with right lower quadrant pain, lethargy, and fever. The computed tomography scan showed a focal thrombosis at the superior mesenteric vein branch and an inflamed appendix. DIAGNOSES: Mesenteric venous thrombosis complicating acute appendicitis. INTERVENTIONS: Intravenous antibiotics along with anticoagulants and laparoscopic appendectomy OUTCOMES:: After 1 month, a follow-up ultrasonography revealed full resolution of the thrombosis. LESSONS: Appendicitis is one of the most frequently encountered causes of pediatric surgical emergencies; therefore, physicians should be conscious of mesenteric venous thrombosis as a possible complication of acute appendicitis, irrespective of whether patients have thrombophilic conditions or not.

RESUMO

OBJECTIVE: To study the clinical features and etiology of abdominal distension in children with different ages. METHODS: A retrospective analysis was performed for the clinical data of 1 561 children who were admitted due to abdominal distension from January 2013 to October 2016, including clinical manifestations, radiological examination, pathological results, and disease diagnosis. RESULTS: Among the 1 561 children, there were 823 neonates (aged <28 days), 307 infants (aged 28 days to 1 year), 186 toddlers (aged 1-3 years), 120 preschool children (aged 3-6 years), 106 school-aged children (aged 6-12 years), and 19 adolescents (aged 12-17 years). Vomiting was the major associated symptom in neonates, infants, toddlers, and school-aged children, abdominal pain was the major associated symptom in pre-school children, and vomiting and abdominal pain were the major associated symptoms in adolescents. Hypoactive bowel sound was the major accompanying sign in neonates and infants, and abdominal tenderness was the major accompanying sign in the other four age groups. Plain abdominal radiograph showed intestinal inflation in neonates and intestinal inflation with an air-fluid level in the other five age groups. Histopathological examination was performed for 339 children and the pathological results of intestinal tissue showed small, few, or poorly developed submucosal ganglion cells in neonates, intestinal inflammation/bleeding/necrosis in infants, and appendicitis in the other age groups. Necrotizing enterocolitis was the main cause of abdominal distension in neonates (34.4%), and intestinal obstruction was the main cause in infants (36.8%), toddlers (52.2%), pre-school children (51.7%), school-aged children (62.3%), and adolescents (52.6%). CONCLUSIONS: Vomiting is a common symptom in children with abdominal distension in all age groups. Neonates and infants with abdominal distension often present with hypoactive bowel sounds, and children over 1 year old mainly suffer from abdominal tenderness. Necrotizing enterocolitis is the most common cause of neonatal abdominal distension, and abdominal distension in the other age groups is mainly attributed to intestinal obstruction.

RESUMO

A few studies have compared patients who were directly admitted with patients who were transferred to a tertiary facility for an appendectomy. However, there have been no reports of an association between the time to transfer and outcome in patients who underwent an appendectomy. As the only tertiary military hospital in South Korea, we occasionally encountered patients who were delayed for transfer due to the military environment. We hypothesize that patients with a longer time to transfer have a worse outcome. This study aimed to evaluate the relationship between the time to transfer and the outcome of patients who underwent an appendectomy.Patients who underwent appendectomy in the tertiary military hospital in South Korea from May 2015 to April 2017 were analyzed retrospectively. The groups were divided by the time for the transfer. Four hours was used as the cut-off point to divide the early and delayed transfer groups. Time from symptom onset to hospitalization, time from diagnosis to surgery, and time from hospitalization to surgery were also analyzed to assess the effect of time for the transfer.A total of 449 patients were analyzed: 293 with direct admission, 110 with early transfer, and 46 with delayed transfer. The time required for transfer was more critical for delaying appendectomy than the time from hospital admission to surgery. There was no difference in outcomes among the groups. When patients were compared according to the perforation, no differences were found in time from hospitalization to surgery, time from diagnosis to surgery, and presence of transfer. Multivariate analysis showed that a greater than 72 hours delay from symptom onset to hospitalization was associated with perforation (odds ratio = 12.61; 95% confidence interval: 3.84-41.40; P < .001).Even if a long transfer time is necessary, an appendectomy can be performed safely if patients were administered antibiotics immediately after diagnosis.

RESUMO

Best management for acute appendicitis (AA) in adults with liver cirrhosis is controversial and needs more investigation. We aimed to examine the impact of different treatment modalities on outcomes in this complex patient population. The Nationwide Inpatient Sample database from 2012 to 2014 was queried to identify AA patients with no cirrhosis, compensated cirrhosis (CC), and decompensated cirrhosis (DC). Each cohort was further stratified according to the treatment type: nonoperative management, open appendectomy, and laparoscopic appendectomy (LA). Chi-square, ANOVA, and binary regression analyses were used to determine differences between groups and risk factors for mortality and complications, with P < 0.05 considered statistically significant. A total of 108,289 AA patients were analyzed; of those, 304 with CC and 134 with DC were identified. Compared with CC and no cirrhosis, DC patients had significantly higher mortality, higher cost, and longer hospital length of stay. LA is accompanied by higher survival, lower cost, shorter duration of hospitalization, and lower incidence of complications across all groups. We conclude that LA is the best management strategy for AA in cirrhotic patients. Even in decompensated cirrhotics, which are associated with worse clinical outcomes, LA is still a favorable option over open appendectomy and nonoperative management.

RESUMO

Delayed presentation of acute appendicitis is associated with increased complications. We hypothesized that the outcomes of appendectomy in delayed presentations of acute appendicitis (>72 hours of pain) were dependent on radiologic findings rather than late presentation. We reviewed records from 2009 to 2015 and analyzed delayed presentations of acute appendicitis. We divided patients into three groups based on specific CT findings: uncomplicated appendicitis (UA), phlegmon or abscess (PA), and other perforated appendicitis (PERF, signs of perforation without abscess or phlegmon). One hundred thirty-eight patients were included in this study (58 in the UA, 67 in the PA, and 13 in the PERF groups). Overall, 78 (57%) patients underwent early appendectomy (EA) and 60 (43%) underwent initial conservative management. The incidence of adverse events was lower in EA than that in initial conservative management (17% vs 42%, P = 0.005). EA in the UA group was associated with shorter hospitalization (3.2 vs 5.6 days, P < 0.001) and less adverse events (6% vs 29%, P < 0.05). Severe adverse events (two colectomies and one fecal fistula) were observed in the PA group. In conclusion, in these late presentations of appendicitis, complicated appendicitis was common. EA was safe in selected patients, however, and associated with decreased adverse events.

RESUMO

To date, consumer health tools available over the web suffer from serious limitations that lead to low quality health- related information. While health data in our world are abundant, access to it is limited because of liability and privacy constraints.The objective of the present study was to develop and evaluate an algorithm-based tool which aims at providing the public with reliable, data-driven information based and personalized information regarding their symptoms, to help them and their physicians to make better informed decisions, based on statistics describing "people like you", who have experienced similar symptoms.We studied anonymized medical records of Maccabi Health Care. The data were analyzed by employing machine learning methodology and Natural Language Processing (NLP) tools. The NLP tools were developed to extract information from unstructured free-text written by Maccabi's physicians.Using machine learning and NLP on over 670 million notes of patients' visits with Maccabi physicians accrued since 1993, we developed predictors for medical conditions based on patterns of symptoms and personal characteristics.The algorithm was launched for Maccabi insured members on January 7, 2018 and for members of Integrity Family Care program in Alabama on May 1, 2018.The App. invites the user to describe her/ his main symptom or several symptoms, and this prompts a series of questions along the path developed by the algorithm, based on the analysis of 70 million patients' visits to their physicians.Users started dialogues with 225 different types of symptoms, answering on average 22 questions before seeing how people similar to them were diagnosed. Users usually described between 3 and 4 symptoms (mean 3.2) in the health dialogue.In response to the question "conditions verified by your doctor", 82.4% of responders (895/1085) in Maccabi reported that the diagnoses suggested by K's health dialogues were in agreement with their doctor's final diagnosis. In Integrity Health Services, 85.4% of responders (111/130) were in agreement with the physicians' diagnosis.While the program achieves very high approval rates by its users, its primary achievement is the 85% accuracy in identifying the most likely diagnosis, with the gold standard being the final diagnosis made by the personal physician in each individual case. Moreover, the machine learning algorithm continues to update itself with the feedback given by users.

RESUMO

BACKGROUND: Controversy exists regarding the use of postoperative antibiotics for nonperforated gangrenous appendicitis. OBJECTIVE: The aim of this study was to evaluate the rate of postoperative infectious complications and the effect of postoperative antibiotic use among patients with nonperforated gangrenous appendicitis. DESIGN: This was a prospective cohort study conducted during 2 months. SETTINGS: A national multicenter observational study was conducted in 62 Dutch hospitals. PATIENTS: All of the consecutive patients who had surgery for suspected acute appendicitis were included. Patients were excluded if no appendectomy was performed or appendectomy was performed for pathology other than acute appendicitis. MAIN OUTCOMES MEASURES: Type of appendicitis was categorized as phlegmonous, gangrenous, or perforated. The primary end point was the rate of infectious complications (intra-abdominal abscess and surgical site infection) within 30 days after appendectomy. Univariable and multivariable logistic regression analyses were performed to identify predictors of infectious complications. RESULTS: A total of 1863 patients were included: 1321 (70.9%) with phlegmonous appendicitis, 181 (9.7%) with gangrenous appendicitis, and 361 (19.4%) with perforated appendicitis. Infectious complications were more frequent in patients with gangrenous versus phlegmonous appendicitis (7.2% vs 3.8%; p = 0.03). This association was no longer statistically significant in multivariable analysis (OR = 1.09 (95% CI, 0.49-2.44)). There was no significant difference in infectious complications between ≤24 hours (n = 57) of postoperative antibiotics compared with >24 hours (n = 124; 3.6% vs 8.9%; p = 0.35) in patients with gangrenous appendicitis. LIMITATIONS: Possible interobserver variability in the intraoperative classification of appendicitis was a study limitation. CONCLUSIONS: Patients with nonperforated gangrenous appendicitis are at higher risk of infectious complications than patients with phlegmonous appendicitis, yet gangrenous disease is not an independent risk factor. Postoperative antibiotic use over 24 hours was not associated with decreased infectious complications. See Video Abstract at http://links.lww.com/DCR/A1000. RESULTADOS POSTOPERATORIOS DE PACIENTES CON APENDICITIS GANGRENOSA NO PERFORADA: UN ANÁLISIS DE COHORTE PROSPECTIVO MULTICÉNTRICO NACIONAL:: Existe controversia sobre el uso de antibióticos postoperatorios para la apendicitis gangrenosa no perforada.El objetivo de este estudio fue evaluar la tasa de complicaciones infecciosas postoperatorias y el efecto del uso de antibióticos postoperatorios en pacientes con apendicitis gangrenosa no perforada.Estudio de cohorte prospectivo realizado durante dos meses.Estudio observacional multicéntrico nacional en 62 hospitales holandeses.Todos los pacientes consecutivos sometidos a cirugía por sospecha de apendicitis aguda. Los pacientes fueron excluidos si no se realizó una apendicectomía o si se realizó una apendicectomía para otra patología que no fuera la apendicitis aguda.El tipo de apendicitis se clasificó como flegmonosa, gangrenosa o perforada. El criterio de valoración primario fue la tasa de complicaciones infecciosas (absceso intraabdominal e infección en el sitio quirúrgico) dentro de los 30 días posteriores a la apendicectomía. Se realizaron análisis de regresión logística univariables y multivariables para identificar predictores de complicaciones infecciosas.Se incluyeron un total de 1863 pacientes: 1321 (70,9%) con apendicitis flegmonosa, 181 (9,7%) con apendicitis gangrenosa y 361 (19,4%) con apendicitis perforada. Las complicaciones infecciosas fueron más frecuentes en pacientes con apendicitis gangrenosa frente a flegmonosa (7,2% frente a 3,8%, p = 0,03). Esta asociación ya no fue estadísticamente significativa en el análisis multivariable (OR 1,09; IC del 95%: 0,49 a 2,44). No hubo diferencias significativas en las complicaciones infecciosas entre ≤ 24 h (n = 57) de los antibióticos postoperatorios en comparación con> 24 h (n = 124) (3,6% vs. 8,9%, p = 0,35) en pacientes con apendicitis gangrenosa.Posible variabilidad interobservador en la clasificación intraoperatoria de la apendicitis.Los pacientes con apendicitis gangrenosa no perforada tienen un mayor riesgo de complicaciones infecciosas que los pacientes con apendicitis flegmonosa, aunque la enfermedad gangrenosa no es un factor de riesgo independiente. El uso de antibióticos postoperatorios durante 24 horas no se asoció con una disminución de las complicaciones infecciosas. Vea el Resumen del Video en http://links.lww.com/DCR/A1000.

RESUMO

The present study evaluated the association between appendectomy and rheumatoid arthritis (RA) using a national sample cohort of the Korean population. In this cohort study, the Korean National Health Insurance Service-National Sample Cohort of individuals ≥20 years old was collected from 2002 to 2013. A total of 14,995 appendectomy participants were 1:4 matched with 59,980 control subjects for age, group, sex, income group, region of residence, hypertension, diabetes, and dyslipidemia. We analyzed the occurrence of RA in both the appendectomy and control groups. Appendectomies were identified using operation codes for appendicitis only. RA was defined by International Classification of Disease-10 codes (M05 or M06) and medication histories. Crude and adjusted hazard ratios (HRs) were analyzed using a stratified Cox proportional hazard model. Subgroup analyses were performed on groups stratified by age and sex. The adjusted HR for RA was 1.02 (95% confidence interval = 0.76-1.38) in the appendectomy group (P = .883). In all of the subgroup analyses according to age and sex, the adjusted HRs for RA were not higher in the appendectomy group than those in the control group. We could not identify any significant relationship between appendectomy and RA.
