Seasonal Variation in Cases of Acute Appendicitis

Surgery Research and Practice, 2021

Objectives To investigate whether the incidence of acute appendicitis increases in summer and whether complicated cases present more in summer. Methods A single-center cross-sectional, retrospective study on 697 cases of appendicitis admitted in the year 2018. Inclusion criteria: patients admitted with acute appendicitis who underwent appendectomy of all ages. Exclusion criteria: conservative management. Analysis was performed using Microsoft Excel. Pearson correlation coefficient was calculated to assess the correlation between monthly incidence of appendicitis and mean temperature in that month. Results Fifty-one patients who were managed conservatively were excluded. Accordingly, 646 patients were included. Ages ranged from three to 77 years. Males comprised the majority (500, 77.4%). Gangrenous, perforated, and purulent appendices were regarded as complicated appendicitis. The highest number of cases were admitted in summer (234), comprising 36.2% of cases. Complicated cases wer...

Patients with recurrent disease and those who underwent interval appendectomy were excluded. Statistical Analysis: Frequency percentages were used in the analysis of data. RESULTS AND CONCLUSIONS: A total of 957 patients underwent appendectomies after excluding the patients who did not meet the inclusion criteria 854 patients were selected for the study. In which 465 occurred in summer, old seasons of which, 389 in the c241 in rainy and 148 in the winter season. In this study we concluded that appendicitis is more common during the summer seasons in India.

Analysis of Risk Factors for Appendicitis in Children: A Multicenter Epidemiological Study

Dicle Medical Journal, 2016

Objectives: In our study, the assessment of age, gender, incidence and seasonal differences in the regions related to appendicitis were investigated. Methods: 676 patients that received an operation following a diagnosis of appendicitis in 3 hospitals from 3 different regions of Turkey occurring at different dates were examined retrospectively after being categorized by region. The differences among groups were compared to each. Results: The mean age of male (63%) (n = 426) and female (37%) (n = 250) patients (total = 676) was 10.8 years (range, 1–18 years). The percentage of female patients in the The Black Sea Region (BR) group was significantly higher (48%) than that in the other two groups (%33 for SR, 30% for MR) (P = 0.001). The frequency of appendicitis was higher (36%) in the spring and winter (25%) than that during summer or fall. The number of cases increased the most in the BR group in spring (47%) (P < 0.001). When the types of appendicitis in the different age groups...

Seasonal variation of acute appendicitis

Pakistan journal of medical sciences

To determine the seasonal variation of acute appendicitis. A total of 320 patients fulfilling the inclusion criteria were enrolled in the study after getting the written informed consent. Appendectomies were performed by consultant surgeons and residents. After surgery histopathological examination of specimens was performed by consultant Histopathologists at Armed Forces Institute of Pathology Rawalpindi and CMH Peshawar. The patients presenting in different four seasons September to November as autumn, December to February as winter, March to May as spring, June to August as summer, were compared to determine seasonal variations. In our study out of all 320 patients 188 (58.75%) were males and 132 (41.25%) were females. Sixty patients (18.75 %) presented in autumn season (Sep-Nov), 52 patients (16.25%) in winter season (Dec-Feb), 78 (24.25%) patients in Spring season (Mar-May).130 (40.62%) patients presented in Summer season (Jun-Aug). There was almost 24.37% increased incidence i...

Seasonal Pattern of Acute Appendicitis in Basrah

Clinical Medicine Research, 2017

Appendicitis is the most common acute surgical condition of the abdomen. The aim of the project is to study the seasonal variation in the incidence of acute appendicitis in Basrah and its correlation to gender, age, presentation and length of hospital stay of affected patients. Patients with acute appendicitis who admitted to the surgical unit in Basrah General hospital during the period from January 2010 to December 2013 were prospectively evaluated according to the demographic features, particularly age and sex, length of hospital stay, seasonal variation and the postoperative outcome. Out of 1261 patients included in this study 57% patients were males and 43% of patient were females with age range from 3-70 years. All the patients treated surgically by open and laparoscopic means. 34 patients found to have perforated appendix, 25 patients presented with abdominal mass and 7 patients were presented with appendicular abscess. A significant seasonal effect was observed, with the rate of acute appendicitis being higher in the summer months. It is concluded that acute appendicitis is more common in males, in those aged 10-19years, and during the summer months.

Monthly variation in acute appendicitis incidence: A 10-year nationwide population-based study

Journal of Surgical Research, 2012

Background: The present study investigated the monthly variation of acute appendicitis and its association with climatic factors (ambient temperature, relative humidity, atmospheric pressure, rainfall, and hours of sunshine) using a nationwide population-based data set in Taiwan. Methods: We identified 237,760 first-time hospitalizations for acute appendicitis from 2000 to 2009. We used the auto-regressive integrated moving average method to examine the monthly variation in the acute appendicitis incidence rates after adjusting for the timetrend effect and seasonality. Results: Throughout the 10-year study period, we found that the monthly incidence rate of acute appendicitis demonstrated a fairly similar monthly pattern for each gender independently and for the pooled data. May through July had the greatest rates, decreasing in August to a trough in February. We used the autoregressive integrated moving average test for seasonality and found a significant difference in the monthly incidence rate for the pooled genders and for the male-and female-only groups (all P < 0.001). Furthermore, the auto-regressive integrated moving average regression models for the male, female, and combined groups all suggested that a significant positive association exists between the monthly incidence rates of acute appendicitis per 100,000 population and the ambient temperature after adjusting for time trends and month. Conclusions: The results of our study have revealed a significant difference in the monthly incidence rate of acute appendicitis.

Factors predictive of complicated appendicitis in children

International Surgery Journal

Background: Clinical features of acute appendicitis are often overlapping with other abdominal pathology in children. This increases the risk of complicated appendicitis (CA). It is still difficult to identify CA preoperatively. The study aims to identify pre operative risk factors in children for CA.Methods: A prospective study was conducted in pediatric surgery unit of department of general surgery of a university hospital of Kathmandu, Nepal. All children up to 16 years diagnosed and operated for appendicitis were included in the study. Based on intraoperative findings and histopathological examination (HPE), patients were grouped in simple appendicitis (SA) and CA. Pre-operative clinical and laboratory variables of between simple and CA were compared. P£0.05 was considered as significant.Results: A total of 73 children were included out of which 61 (83.6%) had SA and 12 (16.4%) had CA. Mean age of participants was 12.8±2.9 years. More than half (64.4%) of the participants were m...
