Review
Today, the prevalence of obesity in the pediatric population has increased dramatically. Acute appendicitis (AA) is the most common surgical condition among pediatric patients. We aimed to investigate the impact of obesity on postoperative outcomes in terms of operative time (OT), length of stay (LOS), surgical site infection (SSI), overall complications, adverse events, and mortality in children undergoing appendectomy for acute appendicitis. An extensive search of the literature in PubMed and Google Scholar was conducted to evaluate the outcomes of normal weight (NW), overweight (OW), and obese (OB) children who underwent appendectomy. Although no statistically significant differences were noted in perioperative outcomes and overall postoperative complications between OW/OB and NW children in the majority of the included studies, prolonged OT and LOS and SSI were found in some studies. Moreover, no differences in terms of readmissions and ED visits were recorded. We conclude that the impact of obesity on postoperative outcomes for children undergoing appendectomy for AA is unclear, and, therefore, no safe conclusions can be drawn with the currently available data. Due to the lack of high-quality studies, further research is required to optimize the surgical approach and prevent unwarranted complications.

Meta-Analysis
OBJECTIVE
This meta-analysis aimed to compare the efficacy and safety of antibiotic treatment and appendectomy for acute uncomplicated appendicitis.
METHODS
We searched the randomized controlled studies (RCTs) comparing appendectomy with antibiotic treatment for uncomplicated acute appendicitis in the electronic database including Pubmed, Embase, Cochrane, Web of Science, CNKI, VIP, and WanFang. The primary outcomes included complication-free treatment success at 1 year, complications, surgical complications, and the complicated appendicitis rates. Secondary outcomes included negative appendicitis, length of hospital stay, the quality of life at 1 month, and the impact of an appendicolith on antibiotic therapy.
RESULTS
Twelve randomized controlled studies were included. Compared with surgery group, the antibiotic group decreased the complication-free treatment success at 1 year (RR 0.81; 95% CI 0.73-0.91; z = 3.65; p = 0.000). Statistically significance was existed between antibiotic group and surgical group with both surgical types(open and laparoscopic) (RR 0.43; 95% CI 0.31-0.58; z = 5.36; p = 0.000), while no between the antibiotic treatment and laparoscopic surgery (RR 0.72; 95% CI 0.41-1.24; z = 1.19; p = 0.236). There was no statistically significant differences between two groups of surgical complications (RR 1.38; 95% CI 0.70-2.73; z = 0.93; p = 0.353), the complicated appendicitis rate (RR 0.71; 95% CI 0.36-1.42; z = 0.96; p = 0.338), negative appendectomy rate (RR 1.11; 95% CI 0.69-1.79; z = 0.43; p = 0.670), duration of hospital stay (SMD 0.08; 95%CI -0.11-0.27; z = 0.80; p = 0.422), and quality of life at 1 month (SMD 0.09; 95%CI -0.03-0.20; z = 1.53; p = 0.127). However, in the antibiotic treatment group, appendicolith rates were statistically higher in those whose symptoms did not improve (RR 2.94; 95% CI 1.28-6.74; z = 2.55; p = 0.011).
CONCLUSIONS
Although the cure rate of antibiotics is lower than surgery, antibiotic treatment is still a reasonable option for patients with uncomplicated acute appendicitis who do not want surgery without having to worry about complications or complicating the original illness.

Review
Adults can accidentally swallow foreign bodies (FBs) with food. In rare occasions, these can lodge in the appendix lumen causing inflammation. This is known as foreign body appendicitis. We conducted this study to review different types and management of appendiceal FBs. A comprehensive search on PubMed, MEDLINE, Embase, Cochrane Library and Google Scholar was performed to detect appropriate case reports for this review. Case reports eligible for this review included patients above 18 years of age with all types of FB ingestion causing appendicitis. A total of 64 case reports were deemed to be eligible for inclusion in this systematic review. The patient mean age was 44.3 ± 16.7 years (range, 18-77). Twenty-four foreign bodies were identified in the adult appendix. They were mainly lead shot pellet, fishbone, dental crown or filling, toothpick, and others. Forty-two percent of the included patients presented with classic appendicitis pain, while 17% were asymptomatic. Moreover, the appendix was perforated in 11 patients. Regarding modalities used for diagnosis, computed tomography (CT) scans confirmed the presence of FBs in 59% of cases while X-ray only managed to detect 30%. Almost all of the cases (91%) were treated surgically with appendicectomy and only six were managed conservatively. Overall, lead shot pellets were the most common foreign body found. Fishbone and toothpick accounted for most of the perforated appendix cases. This study concludes that prophylactic appendicectomy is recommended for the management of foreign bodies detected in the appendix, even if the patient is asymptomatic.

Meta-Analysis
The aim of this study was to analyze the diagnostic performance of Leucine-Rich Alpha-2-Glycoprotein (LRG1) in pediatric acute appendicitis (PAA). We conducted a systematic review of the literature in the main databases of medical bibliography. Two independent reviewers selected the articles and extracted relevant data. Methodological quality was assessed using the QUADAS2 index. A synthesis of the results, standardization of the metrics and 4 random-effect meta-analyses were performed. Eight studies with data from 712 participants (305 patients with confirmed diagnosis of PAA and 407 controls) were included in this review. The random-effect meta-analysis of serum LRG1 (PAA vs control) resulted in a significant mean difference (95% CI) of 46.76 μg/mL (29.26-64.26). The random-effect meta-analysis for unadjusted urinary LRG1 (PAA vs control) resulted in a significant mean difference (95% CI) of 0.61 μg/mL (0.30-0.93). The random-effect meta-analysis (PAA vs control) for urinary LRG1 adjusted for urinary creatinine resulted in a significant mean difference (95% CI) of 0.89 g/mol (0.11-1.66). Conlusion: Urinary LRG1 emerges as a potential non-invasive biomarker for the diagnosis of PAA. On the other hand, due to the high between-study heterogeneity, the results on serum LRG1 should be interpreted with caution. The only study that analyzed salivary LRG1 showed promising results. Further prospective studies are needed to confirm these findings. What is Known: • Pediatric acute appendicitis continues to be a pathology with a high rate of diagnostic error. • Invasive tests, although useful, are a source of stress for patients and their parents. What is New: • LRG1 emerges as a promising urinary and salivary biomarker for the noninvasive diagnosis of pediatric acute appendicitis.

Meta-Analysis Review
Spontaneous Resolution of Uncomplicated Appendicitis may Explain Increase in Proportion of Complicated Appendicitis During Covid-19 Pandemic: a Systematic Review and Meta-analysis.
BACKGROUND
Reports of an increased proportion of complicated appendicitis during the Covid-19 pandemic suggest a worse outcome due to delay secondary to the restrained access to health care, but may be explained by a concomitant decrease in uncomplicated appendicitis. We analyze the impact of the pandemic on the incidences of complicated and uncomplicated appendicitis.
METHOD
We did a systematic literature search in the PubMed, Embase and Web Of Science databases on December 21, 2022 with the search terms (appendicitis OR appendectomy) AND ("COVID" OR SARS-Cov2 OR "coronavirus"). Studies reporting the number of complicated and uncomplicated appendicitis during identical calendar periods in 2020 and the pre-pandemic year(s) were included. Reports with indications suggesting a change in how the patients were diagnosed and managed between the two periods were excluded. No protocol was prepared in advance. We did random effects meta-analysis of the change in proportion of complicated appendicitis, expressed as the risk ratio (RR), and of the change in number of patients with complicated and uncomplicated appendicitis during the pandemic compared with pre-pandemic periods, expressed as the incidence ratio (IR). We did separate analyses for studies based on single- and multi-center and regional data, age-categories and prehospital delay.
RESULTS
The meta-analysis of 100,059 patients in 63 reports from 25 countries shows an increase in the proportion of complicated appendicitis during the pandemic period (RR 1.39, 95% confidence interval (95% CI 1.25, 1.53). This was mainly explained by a decreased incidence of uncomplicated appendicitis (incidence ratio (IR) 0.66, 95% CI 0.59, 0.73). No increase in complicated appendicitis was seen in multi-center and regional reports combined (IR 0.98, 95% CI 0.90, 1.07).
CONCLUSION
The increased proportion of complicated appendicitis during Covid-19 is explained by a decrease in the incidence of uncomplicated appendicitis, whereas the incidence of complicated appendicitis remained stable. This result is more evident in the multi-center and regional based reports. This suggests an increase in spontaneously resolving appendicitis due to the restrained access to health care. This has important principal implications for the management of patients with suspected appendicitis.

Review
OBJECTIVES
To perform a systematic review on the use of magnetic resonance imaging (MRI) of the abdomen to evaluate clinically suspected appendicitis in the general adult population. We examined the diagnostic accuracy, the reported trends of MRI use, and the factors that affect the utility of MRI abdomen, including study duration and cost-benefits.
METHODS
We conducted a systematic literature search on PubMed, MEDLINE, Embase, Web of Science, and Cochrane Library databases. We enrolled primary studies investigating the use of MRI in diagnosing appendicitis in the general adult population, excluding studies that predominantly reported on populations not representative of typical adult appendicitis presentations, such as those focusing on paediatric or pregnant populations.
RESULTS
Twenty-seven eligible primary studies and 6 secondary studies were included, totaling 2,044 patients from eight countries. The sensitivity and specificity of MRI for diagnosing appendicitis were 96% (95% CI: 93-97%) and 93% (95% CI: 80-98%), respectively. MRI can identify complicated appendicitis and accurately propose alternative diagnoses. The duration of MRI protocols in each primary study ranged between 2.26 and 30 minutes, and only one study used intravenous contrast agents in addition to the non-contrast sequences. Decision analysis suggests significant benefits for replacing computed tomography (CT) with MRI and a potential for cost reduction. Reported trends in MRI usage showed minimal utilisation in diagnostic settings even when MRI was available.
CONCLUSIONS
MRI accurately diagnoses appendicitis in the general adult population and improves the identification of complicated appendicitis or alternative diagnoses compared to other modalities using a single, rapid investigation.

Review
BACKGROUND
Ladd's Procedure has been the surgical intervention of choice in the management of congenital intestinal malrotation for the past century. Historically, the procedure included performing an appendectomy to prevent future misdiagnosis of appendicitis, since the location of the appendix will be shifted to the left side of the abdomen. This study consists of two parts. A review of the available literature on appendectomy as part of Ladd's procedure and then a survey sent to pediatric surgeons about their approach (to remove the appendix or not) while performing a Ladd's procedure and the clinical reasoning behind their approach.
METHODS
The study consists of 2 parts: (1) a systematic review was performed to extract articles that fulfill the inclusion criteria; (2) a short online survey was designed and sent by email to 168 pediatric surgeons. The questions in the survey were centered on whether a surgeon performs an appendectomy as part of the Ladd's procedure or not, as well as their reasoning behind either choice.
RESULTS
The literature search yielded five articles, the data from the available literature are inconsistent with performing appendectomy as part of Ladd's procedure. The challenge of leaving the appendix in place has been briefly described with minimal to no focus on the clinical reasoning. The survey demonstrated that 102 responses were received (60% response rate). Ninety pediatric surgeons stated performing an appendectomy as part of the procedure (88%). Only 12% of pediatric surgeons are not performing appendectomy during Ladd's procedure.
CONCLUSION
It is difficult to implement a modification in a successful procedure like Ladd's procedure. The majority of pediatric surgeons perform an appendectomy as part of its original description. This study has identified gaps in the literature pertaining to analyze the outcomes of performing Ladd's procedure without an appendectomy which should be explored in future research.

BACKGROUND
Point-of-Care Ultrasound (POCUS) is a quick, useful, noninvasive, and inexpensive diagnostic tool used for the diagnosis of trauma, abdominal pain, dyspnea, and chest pain in the emergency department (ED). However, the diagnostic accuracy of ultrasound in the ED may be different from those reported in previous studies owing to the setting and time constraints in ED.
METHODS
We conducted our study in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. A literature search was conducted using databases on US National Library of Medicine's database of biomedical literature, Ovid MEDLINE, online database of biomedical articles, and the collection of databases of systematic reviews and other evidence. The inclusion criteria were the use of bedside ultrasound as a diagnostic tool for acute appendicitis in the ED and the available data on diagnostic parameters such as sensitivity, specificity, and positive and negative predictive values (NPV). We constructed forest plots and summary receiver operating characteristic curves to evaluate the diagnostic accuracy of bedside ultrasound for acute appendicitis in the ED.
RESULTS
A total of 21 studies that met the inclusion criteria of this study were included for analysis. The overall pooled sensitivity was 0.81 (95% CI, 0.78-0.83), whereas the pooled specificity was 0.87 (95% CI, 0.85-0.88). However, the I2 test showed 91.7% and 90.9% heterogeneity in the sensitivity and specificity values, respectively. The summary receiver operating characteristic curves showed high levels of accuracy, as evidenced by an area under the curve of 0.9249 (standard error: 0.0180).
CONCLUSIONS
The use of ultrasound for the diagnosis of acute appendicitis in the ED showed that ultrasound has high overall sensitivity and specificity for the diagnosis of acute appendicitis. however, high heterogeneity among the included studies was observed.

Meta-Analysis Review
BACKGROUND
Intraoperative peritoneal lavage (IOPL) with saline has been widely used in surgical practice. However, the effectiveness of IOPL with saline in patients with intra-abdominal infections (IAIs) remains controversial. This study aims to systematically review randomized controlled trials (RCTs) evaluating the effectiveness of IOPL in patients with IAIs.
METHODS
The databases of PubMed, Embase, Web of Science, Cochrane library, CNKI, WanFang, and CBM databases were searched from inception to December 31, 2022. Random-effects models were used to calculate the risk ratio (RR), mean difference, and standardized mean difference. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) was used to rate the quality of the evidence.
RESULTS
Ten RCTs with 1318 participants were included, of which eight studies on appendicitis and two studies on peritonitis. Moderate-quality evidence showed that the use of IOPL with saline was not associated with a reduced risk of mortality (0% vs. 1.1%; RR, 0.31 [95% CI, 0.02-6.39]), intra-abdominal abscess (12.3% vs. 11.8%; RR, 1.02 [95% CI, 0.70-1.48]; I = 24%), incisional surgical site infections (3.3% vs. 3.8%; RR, 0.72 [95% CI, 0.18-2.86]; I = 50%), postoperative complication (11.0% vs. 13.2%; RR, 0.74 [95% CI, 0.39-1.41]; I = 64%), reoperation (2.9% vs. 1.7%; RR,1.71 [95% CI, 0.74-3.93]; I = 0%) and readmission (5.2% vs. 6.6%; RR, 0.95 [95% CI, 0.48-1.87]; I = 7%) in patients with appendicitis when compared to non-IOPL. Low-quality evidence showed that the use of IOPL with saline was not associated with a reduced risk of mortality (22.7% vs. 23.3%; RR, 0.97 [95% CI, 0.45-2.09], I = 0%) and intra-abdominal abscess (5.1% vs. 5.0%; RR, 1.05 [95% CI, 0.16-6.98], I = 0%) in patients with peritonitis when compared to non-IOPL.
CONCLUSION
IOPL with saline use in patients with appendicitis was not associated with significantly decreased risk of mortality, intra-abdominal abscess, incisional surgical site infection, postoperative complication, reoperation, and readmission compared with non-IOPL. These findings do not support the routine use of IOPL with saline in patients with appendicitis. The benefits of IOPL for IAI caused by other types of abdominal infections need to be investigated.
