Abstract
AIMS Laparoscopic appendectomy (LA) for acute appendicitis (AA) is one of the most performed procedures. The effects of peritoneal lavage (PL) and the reasons to perform it have not been cleared and all meta-analyses didn't show a statistical advantage to prevent infectious complications. This study aims to investigate surgeons' perceptions during LA, comparing intraoperative findings with histological results, and exploring how surgeons' subjectivity influences the decision-making process on PL. METHODS Data were extracted from the two-year data lock from REsiDENT-1 registry, a prospective resident-led multicentre observational trial. This study investigates the relationships between PL and postoperative intraabdominal abscesses (pIAA) introducing a classification for AA to standardize the intraoperative grading. We included pre, intra, and postoperative variables. We applied our classification proposal, used a five-point Likert scale (Ls) to assess subjective LA difficulty and ran a concordance analysis between the assessment of AA and histology. Subsequently, a multivariate logistic regression model was built to find factors influencing PL. RESULTS 561 patients were enrolled from twenty-one hospitals and 51 residents. 542 procedures were included in the logistic regression analysis and 441 in the concordance analysis, due to missing data. PL was used in 222 LA (39, 6%). We discovered a moderate positive monotonic relationship between surgical evaluation and histology, p < 0.001. Despite this, the reliability of the surgeon's assessment of appendicitis is progressively lower for gangrenous and perforated forms. The increasing grade of contamination, the increasing grade of subjective difficulty and the intraoperative finding of a gangrenous or perforated appendicitis were independent predictors of PL. CONCLUSION This study shows how surgeons' evaluation of AA severity overestimated more than half of gangrenous or perforated appendices with the perception of a challenging procedure. These perceptions influenced the choice of PL. We proved that the evaluation during LA could be affected by subjectivity with a non-negligible impact on the decision-making process.

Cureus 2022; 14:e27592. [PMID: 36059326 PMCID: PMC9434359 DOI: 10.7759/cureus.27592] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 08/02/2022] [Indexed: 11/17/2022] Open
Abstract
Introduction In-patient delay is associated with increased mortality in patients with alimentary tract perforations. Access to surgical care is a glaring health issue in low-middle income countries (LMICs), where patient presentation is also delayed for a myriad of reasons, which can be broadly categorized as social/cultural, financial, and structural in their nature. The impact these delays have on surgical outcomes in low-middle income countries is not known. Methods A retrospective cohort study of patients who underwent emergency laparotomy for alimentary tract perforation from July 2015 to June 2018 was conducted at a tertiary care hospital in Karachi, Pakistan. Time was recorded in two variables: symptom onset to emergency room presentation (ERT) and emergency room to operation room time (ORT). Results Overall, 80 patients were included in the study. The 12 (15%) patients who expired were significantly older (57 ± 17.7 years of age), had a higher Charlson Comorbidity Index and had longer ORT [median ORT in hours-discharged vs expired: 8.2 (IQR 5-15) vs 16 (IQR 12-28) p=0.02]. ERT was also longer but lacked statistical significance [median ERT in hours-discharged vs expired: 24 (IQR 22-72) vs 48 (IQR 24-120) p=0.19]. Multivariable logistic regression analysis revealed ORT to be significantly associated with mortality [odds ratio (OR): 1.02, 95% confidence interval (CI): 1.003-1.041; p=0.02]. Adjusted Cox regression analysis showed that each hour of ORT increased the risk of mortality by 1.5% [hazard ratio (HR) 1.015, 95% CI 1.001-1.030]. Conclusion Inpatient delays increased the risk of mortality for patients undergoing emergency laparotomy for alimentary tract perforation. Larger sample sizes and prospective studies are needed to better understand this relationship and the impact pre-hospital delays have on outcomes.

Abstract
Background For elderly patients with mild clinical symptoms of uncomplicated appendicitis(UA), non-surgical treatment has been shown to be feasible, whereas emergency surgical treatment is recommended in elderly patients with complicated appendicitis(CA), but it is still challenging to accurately distinguish CA and UA before treatment. This study aimed to develop a predictive model to assist clinicians to quickly determine the type of acute appendicitis. Methods We retrospectively studied the clinical data of elderly patients with acute appendicitis who visited the First Affiliated Hospital of Anhui University of Traditional Chinese Medicine from January 2012 to January 2022. The patients were divided into UA group and CA group, and the general conditions, medical history, physical examination, laboratory examination and imaging examination were compared between the two groups, and SPSS 26.0 and R 4.0.2 software were used to establish CA clinic. Predict the model, and validate it internally. Results The clinical data of 441 elderly patients with acute appendicitis were collected, 119 patients were excluded due to incomplete clinical data or other diseases. Finally, 332 patients were included in the study and divided into UA group (n = 229) and CA group (n = 103). By analyzing the clinical data of the two groups of patients, the duration of abdominal pain [OR = 1.094, 95% CI (1.056–1.134)], peritonitis [OR = 8.486, 95% CI (2.017–35.703))] and total bilirubin [OR = 1.987, 95% CI (1.627–2.426)] were independent predictors of CA (all p < 0.01). The model's Area Under Curve(AUC) = 0.985 (95% CI, 0.975–0.994). After internal verification by Bootstrap method, the model still has high discriminative ability (AUC = 0.983), and its predicted CA curve is still in good agreement with the actual clinical CA curve. Conclusion We found that a clinical prediction model based on abdominal pain duration, peritonitis, and total bilirubin can help clinicians quickly and effectively identify UA or CA before treatment of acute appendicitis in the elderly, so as to make more scientific clinical decisions.

CT based Acute Appendicitis Severity Index for acute appendicitis and validate its effectiveness in predicting complicated appendicitis. Emerg Radiol 2021; 28:921-927. [PMID: 34032950 DOI: 10.1007/s10140-021-01950-1] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2021] [Accepted: 05/19/2021] [Indexed: 10/21/2022]
Abstract
AIM To propose a CT-based scoring system called Acute Appendicitis Severity Index (AASI) for diagnosis of acute appendicitis and validates its effectiveness in predicting complicated appendicitis. SUBJECTS AND METHODS Retrospective analyses of CT images of 120 adult patients with pathologically proven uncomplicated (n = 64) and complicated (n = 56) acute appendicitis were performed. All patients had undergone a CT scan of the abdomen and pelvis using 320 multi-detectors computed tomography with Adaptive Iterative Dose Reduction 3D (AIDR 3D). CT image parameters were identified and used to develop a CT-based scoring system (AASI) to predict the severity of acute appendicitis and its outcome. All image analysis was performed by 2 radiologists and the total score was assigned to each patient based on the proposed CT scoring system. Validation of the effectiveness of the proposed scoring system (AASI) was done using statistical models. RESULTS The mean and standard deviation of AASI was found to be significantly higher (P value = 0.001) in the complicated appendicitis group (observer 1 = 10.2 ± 1.6 and observer 2 = 9.63 ± 2.3) as compared to that in uncomplicated acute appendicitis group (observer 1 = 7.09 ± 2.2 and observer 2 = 6.38 ± 1.9). There was an excellent interobserver agreement of the Acute Appendicitis Severity Index for both the uncomplicated and complicated appendicitis groups (K = 0.89, 95% CI = 0.87-0.92, P = 0.001). The cutoff value for AASI used to predict complicated appendicitis was taken as 9.5 and 8.5. This resulted in an AUC of 0.877 and 0.848, accuracy of 83% and 81%, the sensitivity of 75% and 80%, the specificity of 90% and 81%, the positive predictive value of 87% and 78%, and a negative predictive value of 81% and 83% by both reviewers respectively. CONCLUSION The proposed CT-based AASI is a reliable parameter for the prediction of complicated appendicitis.

Increased Incidence of Perforated Appendicitis in Children During COVID-19 Pandemic in a Bavarian Multi-Center Study. Front Pediatr 2021; 9:683607. [PMID: 34026695 PMCID: PMC8138624 DOI: 10.3389/fped.2021.683607] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/21/2021] [Accepted: 04/12/2021] [Indexed: 12/29/2022] Open
Abstract
Introduction: Since early 2020 the COVID-19 pandemic and statutory preventive reorganization of treatment capacities with cancellation of elective surgery as well as curfew regulations led to vastly decreased utilization of primary health care. Materials and Methods: To assess whether there are negative effects on pediatric acute care in Bavaria during the spring 2020 lockdown a state-wide retrospective multi-center study was performed to analyze the rate of perforated appendicitis during lockdown. Children who have been operated on during the corresponding period in 2018/19 served as control group. Results: Overall, 514 patients (292 boys, 222 girls) were included (2020: 176 patients; 2019: 181 patients; 2018: 157 patients). Median age was 11.2 years. Four hundred thirty-nine patients (85.4%) underwent laparoscopic surgery, 69 (13.4%) open surgery and 1.2% underwent conversion from laparoscopic to open surgery. In 2020 a perforation rate of 27.8% (49/176 patients) was found, in 2018-2019 perforation rate was 20.7% (70/338 patients, p = 0.0359, Cochran-Mantel-Haenszel-Test). Subgroup analysis showed that in younger patients (≤ 11.2 years), in 2020 perforation rate was significantly higher with 37.6% (32/85 patients), while 22.2% (39/176) in 2018/2019 (p = 0.014, Fisher's exact test).In boys perforation rate was significantly higher in 2020 with 35.0% (35/100 patients) compared to 21.4% in 2018-2019 (p = 0.0165, Fisher's exact test). Conclusion: During the period of curfew regulations in Bavaria the rate of perforated appendicitis in childhood increased significantly, especially in younger children and boys. Potentially this has to be attributed to delayed presentation to pediatric surgery care. Because of potential long-term sequelae of perforated appendicitis these adverse effects during curfew have to be taken into account for future political decision making to ensure reasonable patient care and avoid collateral damage in near-future or on-going pandemic situations.

Abstract
PURPOSE To identify discrepancies between intraoperative and histological evaluations of the appendix in acute appendicitis and to evaluate the effect on surgical outcome. METHODS Data was used from our previous multicentre, prospective, cohort study of patients with suspected acute appendicitis. Appendices were scored during intraoperative and histological evaluation as uncomplicated or complicated appendicitis. Primary outcome was percentage of concordance between intraoperative and histological evaluation. Secondary outcomes were (infectious) postoperative complications, length of hospital stay, hospital re-admission and re-intervention rate, all within 30 days of surgery. RESULTS A total of 1850 patients were included. In 65.7% (1215/1850) of the appendices, the intraoperative evaluation was uncomplicated and in 34.3% (635/1850), complicated appendicitis. Patients with uncomplicated appendicitis had a postoperative course with significantly less postoperative complications (7.2% vs 24.3%), a shorter length of hospital stay (2 vs 5 days) and a lower re-admission (4.2% vs 9.6%) and re-intervention rate (1.1% vs 4.3%) than intraoperative complicated appendicitis (p < 0.001). In 93.5% (1136/1215) of the intraoperative uncomplicated patients and in 46.6% (296/635) of the intraoperative complicated patients, there was an agreement with pathology (Kappa 0.45). In 23.9% (81/339) of patients with intraoperative complicated and histological uncomplicated appendicitis, a postoperative complication was observed, which was similar to the postoperative complication rate of complicated appendicitis both on intraoperative and histological evaluation (24.7% (73/296)). CONCLUSIONS There is a moderate agreement between a surgeon and pathologist in diagnosing patients with complicated appendicitis. However, the intraoperative diagnosis of complicated appendicitis was significantly associated with postoperative complications. Routine histological evaluation should be preserved for excluding malignancies in suspect appendices.

Abstract
UNLABELLED Acute appendicitis is the most frequent urgent abdominal surgical pathology in children. Therapeutic decisions in patients who have undergone an appendectomy are made based on the macroscopic findings at the moment of surgery. There is high variability between surgical and histopathological findings. METHOD Concordance among surgeons and pathologists regarding the diagnosis and classification of acute appendicitis was assessed in children who have undergone an appendectomy. Surgical site infection (SSI) incidence was measured for both the surgical and pathological classification. RESULTS The statistical analysis included 1092 children. The pathologists confirmed the presence of appendicitis in 90.4% of the patients. Concordance in the diagnosis of appendicitis among surgeons and pathologists was weak (kappa 0.57), while concordance in the classification of perforated or non-perforated appendicitis was moderate (kappa 0.7). There were no significant differences in these findings determined by the surgeons' experience or the open or laparoscopic approach. In the discordant group of 70 patients in which the surgeon classified the appendicitis as non-perforated but the pathologist classified as perforated, just one patient developed an intra-abdominal abscess. CONCLUSIONS The classification of appendicitis as perforated or non-perforated shows moderate concordance between the surgical and histopathological diagnosis. This concordance is not determined by the surgeons' experience or the surgical approach. TYPE OF STUDY Diagnostic Test LEVEL OF EVIDENCE: Level II.

Abstract
Background: Acute appendicitis (AA) is one of the most common causes of abdominal pain requiring surgical intervention. Approximately 20% of AA cases are characterized by complications such as gangrene, abscesses, perforation, or diffuse peritonitis, which increase patients' morbidity and mortality. Diagnosis of AA can be difficult, and evaluation of clinical signs, laboratory index and imaging should be part of the management of patients with suspicion of AA.Methods: This consensus statement was written in relation to the most recent evidence for diagnosis and treatment of AA, performing a literature review on the most largely adopted scientific sources. The members of the SPIGC (Italian Polispecialistic Society of Young Surgeons) worked jointly to draft it. The recommendations were defined and graded based on the current levels of evidence and in accordance with the criteria adopted by the American College of Chest Physicians (CHEST) for the strength of the recommendations.Results: Fever and migratory pain tend to be present in patients with suspicion of AA. Laboratory and radiological examinations are commonly employed in the clinical practice, but today also scoring systems based on clinical signs and laboratory data have slowly been adopted for diagnostic purpose. The clinical presentation of AA in children, pregnant and elderly patients can be unusual, leading to more difficult and delayed diagnosis. Surgery is the best option in case of complicated AA, whereas it is not mandatory in case of uncomplicated AA. Laparoscopic surgical treatment is feasible and recommended. Postoperative antibiotic treatment is recommended only in patients with complicated AA.

Risk factors for serious morbidity, prolonged length of stay and hospital readmission after laparoscopic appendectomy - results from Pol-LA (Polish Laparoscopic Appendectomy) multicenter large cohort study. Sci Rep 2019; 9:14793. [PMID: 31616053 PMCID: PMC6794313 DOI: 10.1038/s41598-019-51172-2] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2019] [Accepted: 09/26/2019] [Indexed: 12/19/2022] Open
Abstract
Laparoscopic appendectomy (LA) for treatment of acute appendicitis has gained acceptance with its considerable benefits over open appendectomy. LA, however, can involve some adverse outcomes: morbidity, prolonged length of hospital stay (LOS) and hospital readmission. Identification of predictive factors may help to identify and tailor treatment for patients with higher risk of these adverse events. Our aim was to identify risk factors for serious morbidity, prolonged LOS and hospital readmission after LA. A database compiled information of patients admitted for acute appendicitis from eighteen Polish and German surgical centers. It included factors related to the patient characteristics, peri- and postoperative period. Univariate and multivariate logistic regression models were used to identify risk factors for serious perioperative complications, prolonged LOS, and hospital readmissions in acute appendicitis cases. 4618 laparoscopic appendectomy patients were included. First, although several risk factors for serious perioperative complications (C-D III-V) were found in the univariate analysis, in the multivariate model only the presence of intraoperative adverse events (OR 4.09, 95% CI 1.32-12.65, p = 0.014) and complicated appendicitis (OR 3.63, 95% CI 1.74-7.61, p = 0.001) was statistically significant. Second, prolonged LOS was associated with the presence of complicated appendicitis (OR 2.8, 95% CI: 1.53-5.12, p = 0.001), postoperative morbidity (OR 5.01, 95% CI: 2.33-10.75, p < 0.001), conversions (OR 6.48, 95% CI: 3.48-12.08, p < 0.001) and reinterventions after primary procedure (OR 8.79, 95% CI: 3.2-24.14, p < 0.001) in the multivariate model. Third, although several risk factors for hospital readmissions were found in univariate analysis, in the multivariate model only the presence of postoperative complications (OR 10.33, 95% CI: 4.27-25.00), reintervention after primary procedure (OR 5.62, 95% CI: 2.17-14.54), and LA performed by resident (OR 1.96, 95% CI: 1.03-3.70) remained significant. Laparoscopic appendectomy is a safe procedure associated with low rates of complications, prolonged LOS, and readmissions. Risk factors for these adverse events include complicated appendicitis, postoperative morbidity, conversion, and re-intervention after the primary procedure. Any occurrence of these factors during treatment should alert the healthcare team to identify the patients that require more customized treatment to minimize the risk for adverse outcomes.

Abstract
Objective To evaluate the correlation of morphological criteria of the cecal appendix
using computed tomography (CT) and the possible risk of developing acute
appendicitis. Materials and Methods Cases were defined as patients with surgically confirmed acute appendicitis
who had undergone CT at least twice: at diagnosis and at least one month
prior. Controls were defined as emergency patients with abdominal pain who
had undergone abdominal CT that excluded acute appendicitis and had also
undergone CT at least one month before. Results 100 cases and 100 controls were selected for inclusion in the final analysis.
Comparisons between the cases and controls revealed the following: mean
transverse diameter of 0.6 cm (range, 0.4-1.0 cm) versus 0.6 cm (range,
0.6-0.8 cm; p = 0.37); mean length of 6.6 cm (range,
3.5-9.7 cm) versus 6.6 cm (range, 4.5-8.3 cm; p = 0.87);
mean angle of 100° (range, 23-178°) versus 86° (range, 43-160°;
p = 0.01); vertical descending orientation in 56%
versus 45% (p = 0.2); absence of gas in 69% versus 77%
(p = 0.34); and presence of an appendicolith in 17%
versus 8% (p = 0.08). Conclusion Hypothetical risk factors for obstruction of the vermiform appendix detected
on CT were not associated with acute appendicitis. That suggests that
factors other than those related to mechanical obstruction are implicated in
the pathogenesis of acute appendicitis.

Abstract
BACKGROUND This study determined the prevalence of complicated appendicitis in elderly patients diagnosed preoperatively with uncomplicated appendicitis. METHODS Patients with a preoperative diagnosis of uncomplicated appendicitis at an academic hospital from 11/2013 to 05/2017 were reviewed. Patients ≥65 years were compared to those younger. Pathology reports were categorized as either uncomplicated or complicated (COMP). The primary outcome was the prevalence of COMP appendicitis. RESULTS The prevalence of COMP appendicitis increased with age after 20 years with an abrupt increase after 65 years. Patients ≥65 years were more likely to have COMP appendicitis (48.1% vs. 15.5%; OR: 5.1; p < 0.01) and prolonged stays (3.8 vs. 2.3 days; p < 0.01). CONCLUSION Nearly half of elderly patients had pathologic confirmation of complicated appendicitis despite no preoperative clinical or radiographic suspicion for complicated appendicitis. Nonoperative management of acute appendicitis in the elderly may not be appropriate due to the high rate of unexpected complicated appendicitis.

Abstract
Introduction Factors associated with complicated appendicitis have been inconsistently identified. Moreover, studies are lacking from low and low-middle countries where access to surgical care is limited. Our objective was to identify factors predicting complicated appendicitis as diagnosed intraoperatively in a low-middle income country hospital. Methodology Retrospective case-control study of patients who underwent laparoscopic appendectomy from 01/2008 to 12/2015 was completed. Based on intraoperative diagnosis of complicated appendicitis, patients were divided into two groups; those with complicated appendicitis (CA) and those who had non-complicated appendicitis (NCA). CT scans were further reviewed to identify presence of appendicolith. Result Of the 442 patients included, 88 (20%) patients were in the CA group while 354 (80%) patients were in the NCA group. Patients in the CA group were older [CA vs. NCA: 34.6 ± 14 vs. 30.4 ± 11.5; p-value < 0.001], had symptoms for longer duration [CA vs. NCA: 2 ± 1.2 vs. 1.5 ± 0.8; p-value: 0.001] and had a greater proportion of patients with appendicoliths [CA vs. NCA: 37 (42%) vs. 84 (23.7%); p-value: 0.001]. On multivariable regression analysis, patients with complicated appendicitis had greater odds of having appendicoliths (OR: 2.4, 95% CI: 1.4-4.07; p-value < 0.001) and symptoms for a longer duration (OR: 1.57, 95% CI: 1.25-1.97; p-value < 0.001). Conclusion Patients with complicated appendicitis had greater odds of having appendicoliths and symptoms for a longer duration. Further studies are warranted in low and low-middle income countries to gauge the impact delay in presentation and intervention has on appendicitis and its outcomes.

World J Emerg Surg 2018; 13:28. [PMID: 29988464 PMCID: PMC6025707 DOI: 10.1186/s13017-018-0191-4] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2018] [Accepted: 06/22/2018] [Indexed: 12/11/2022] Open
Abstract
Background Appendectomy is increasingly performed as a 'short stay' or 'ambulatory' procedure, yet there is no consensus for selection of patients with acute appendicitis for ambulatory surgery (AS). We aimed to compare characteristics and outcomes of complicated and uncomplicated appendectomies performed in ambulatory vs. conventional settings, and to determine factors associated with unexpected re-consultations and re-hospitalizations. Methods The authors reviewed a consecutive series of 185 laparoscopic appendectomies. Whenever possible, patients were offered AS, defined as 'discharge on the same working day.' Multivariable regressions were performed to determine associations of unexpected re-consultations and re-hospitalizations with surgery type (ambulatory or conventional) and patient characteristics (age, gender, obesity, symptoms, appendicolith, perforations, appendix diameter, serologic results, American Society of Anesthesiologists score, and Saint-Antoine score). Results From the initial cohort, 117 patients (63.2%) were eligible for AS, of which 8 had peri- or post-operative contraindications. Therefore, 109 patients (58.9%) were operated by AS, with median length of stay 8.5 h (range, 3.3-20.5). Ambulatory cases had a lower incidence of complications (11.9%) than conventional cases (25.0%) (p = 0.029). Uni- and multi-variable regressions revealed that unexpected re-consultations were not significantly associated with any of the pre- or peri-operative variables but that unexpected re-hospitalizations were 4 times more likely for patients with appendicolith (OR, 4.32; p = 0.04). Conclusions Ambulatory surgery could be considered as a standard procedure for both complicated and uncomplicated acute appendicitis. Appendicolith was found to be an independent risk factor for unexpected re-hospitalization and should therefore trigger closer monitoring.
