Abstract
INTRODUCTION Generative artificial intelligence (AI) chatbots have recently been posited as potential sources of online medical information for patients making medical decisions. Existing online patient-oriented medical information has repeatedly been shown to be of variable quality and difficult readability. Therefore, we sought to evaluate the content and quality of AI-generated medical information on acute appendicitis. METHODS A modified DISCERN assessment tool, comprising 16 distinct criteria each scored on a 5-point Likert scale (score range 16-80), was used to assess AI-generated content. Readability was determined using the Flesch Reading Ease (FRE) and Flesch-Kincaid Grade Level (FKGL) scores. Four popular chatbots, ChatGPT-3.5 and ChatGPT-4, Bard, and Claude-2, were prompted to generate medical information about appendicitis. Three investigators independently scored the generated texts blinded to the identity of the AI platforms. RESULTS ChatGPT-3.5, ChatGPT-4, Bard, and Claude-2 had overall mean (SD) quality scores of 60.7 (1.2), 62.0 (1.0), 62.3 (1.2), and 51.3 (2.3), respectively, on a scale of 16-80. Inter-rater reliability was 0.81, 0.75, 0.81, and 0.72, respectively, indicating substantial agreement. Claude-2 demonstrated a significantly lower mean quality score compared to ChatGPT-4 (p = 0.001), ChatGPT-3.5 (p = 0.005), and Bard (p = 0.001). Bard was the only AI platform that listed verifiable sources, while Claude-2 provided fabricated sources. All chatbots except for Claude-2 advised readers to consult a physician if experiencing symptoms. Regarding readability, FKGL and FRE scores of ChatGPT-3.5, ChatGPT-4, Bard, and Claude-2 were 14.6 and 23.8, 11.9 and 33.9, 8.6 and 52.8, 11.0 and 36.6, respectively, indicating difficulty readability at a college reading skill level. CONCLUSION AI-generated medical information on appendicitis scored favorably upon quality assessment, but most either fabricated sources or did not provide any altogether. Additionally, overall readability far exceeded recommended levels for the public. Generative AI platforms demonstrate measured potential for patient education and engagement about appendicitis.

Abstract
BACKGROUND ChatGPT has substantial potential to revolutionize medical education. We aim to assess how medical students and laypeople evaluate information produced by ChatGPT compared to an evidence-based resource on the diagnosis and management of 5 common surgical conditions. METHODS A 60-question anonymous online survey was distributed to third- and fourth-year U.S. medical students and laypeople to evaluate articles produced by ChatGPT and an evidence-based source on clarity, relevance, reliability, validity, organization, and comprehensiveness. Participants received 2 blinded articles, 1 from each source, for each surgical condition. Paired-sample t-tests were used to compare ratings between the 2 sources. RESULTS Of 56 survey participants, 50.9% (n = 28) were U.S. medical students and 49.1% (n = 27) were from the general population. Medical students reported that ChatGPT articles displayed significantly more clarity (appendicitis: 4.39 vs 3.89, P = .020; diverticulitis: 4.54 vs 3.68, P < .001; SBO 4.43 vs 3.79, P = .003; GI bleed: 4.36 vs 3.93, P = .020) and better organization (diverticulitis: 4.36 vs 3.68, P = .021; SBO: 4.39 vs 3.82, P = .033) than the evidence-based source. However, for all 5 conditions, medical students found evidence-based passages to be more comprehensive than ChatGPT articles (cholecystitis: 4.04 vs 3.36, P = .009; appendicitis: 4.07 vs 3.36, P = .015; diverticulitis: 4.07 vs 3.36, P = .015; small bowel obstruction: 4.11 vs 3.54, P = .030; upper GI bleed: 4.11 vs 3.29, P = .003). CONCLUSION Medical students perceived ChatGPT articles to be clearer and better organized than evidence-based sources on the pathogenesis, diagnosis, and management of 5 common surgical pathologies. However, evidence-based articles were rated as significantly more comprehensive.

Abstract
Acute appendicitis in the pediatric population is a pathology of heterogeneous presentation that is currently diagnosed using various criteria or predictive scales, which have proven not to be sufficiently accurate to be standardized, however, methods have been created to establish a more accurate diagnosis, an aspect that has been provided by artificial intelligence, which through different algorithms has the ability to show the patient's condition and the most appropriate intervention for this, thus reducing the rate of unnecessary interventions and therefore possible related complications.

Abstract
A Gram-negative, facultatively anaerobic, short rod-shaped bacterium, designated as strain HZ0627T, was isolated from the appendiceal pus of a patient with appendicitis in Yongzhou, Hunan, China. This strain was subjected to comprehensive phenotypic, phylogenetic, and genomic analyses using polyphasic taxonomic methods. Phylogenetic analysis of the 16S rRNA gene sequence revealed that this strain belonged to the genus Proteus and the family Morganellaceae, whereas that based on the rpoB gene sequence and phylogenomic analysis demonstrated that this strain was distinctly separated from other type strains of Proteus species. Moreover, whole-genome-based analyses, including in silico DNA-DNA hybridization (isDDH) and average nucleotide identity (ANI), revealed that strain HZ0627T had much lower isDDH rates (24.5-55.6%) and ANI (82.04-93.90%) than those of the thresholds (i.e., 70% and 95%, respectively) for species delineation, when compared to the type strains of other Proteus species. The cellular fatty acid profile of strain HZ0627T was dominated by C16:0 (34.5%), cyclo C17:0 (25.8%), C14:0 (12.6%), C16:1 iso I/14:0 3-OH (7.7%), C18:1ω7c/18:1ω6c (6.5%), and C16:1ω7c/16:1ω6c (4.9%), which clearly differentiated it from the documented type strains of Proteus species. In addition, several specific physiological traits, including optimal growth temperature, tolerance to sodium chloride, and carbon source utilization, differed from those of other Proteus species. Therefore, we propose the name Proteus appendicitidis sp. nov. for strain HZ0627T (= CCTCC AB 2022380T = KCTC 92986T), which represents the type strain of this novel Proteus species.

Abstract
Systemic sclerosis (SSc), also known as scleroderma, is an autoimmune-related connective tissue disease with a complex and unknown pathophysiological mechanism with genes association. Several articles have reported a high prevalence of thyroid disease in SSc patients, while one study suggested a potential contribution of appendicitis to the development of SSc. To investigate this causal association, we conducted Mendelian randomization (MR) analysis using instrumental variables (IVs) to assess exposure and outcome. In the MR study involving two cohorts, all analyses were conducted using the TwoSampleMR package in R (version 4.3.0). Single nucleotide polymorphisms (SNPs) meeting a statistically significant threshold of 5E-08 were included in the analysis. Multiple complementary approaches including MR-IVW, MR-Egger, weighted median, simple mode, and weighted mode were employed to estimated the relationship between the exposure and outcome. Leave-one-out analysis and scatter plots were utilized for further investigation. Based on the locus-wide significance level, all of the MR analysis consequences manifested no causal association between the risk of appendicitis with SSc (IVW OR 0.319, 95% CI 0.063-14.055, P = 0.966). Negative causal effects of autoimmune thyroiditis (AT) on SSc (IVW OR 0.131, 95% CI 0.816-1.362, P = 0.686), Graves' disease (GD) on SSc (IVW OR 0.097, 95% CI 0.837-1.222, P = 0.908), and hypothyroidism on SSc (IVW OR 1.136, 95% CI 0.977-1.321, P = 0.096) were derived. The reverse MR revealed no significant causal effect of SSc on thyroid disease. According to the sensitivity analysis, horizontal pleiotropy was unlikely to distort the causal estimates. The consequences indicated no significant association between AT, GD, and hypothyroidism with SSc. Similarly, there was no observed relationship with appendicitis.

Abstract
A 65-year-old woman was admitted to our hospital with complaints of lower abdominal pain. Her physical examination was unremarkable. The results of routine laboratory testing were within the normal limits. In addition, abdominal CT was normal. Colonoscopy showed a cecum submucosal tumor with a pale yellow surface. Endoscopic ultrasound revealed homogeneous hypoechoic lesions originated from submucosal layer. ESD was subsequently performed to remove the submucosal lesion. During the ESD procedure, fecal outflowed from appendix opening . Yellow fecal-like material was visible after submucosal incision. The trap electrocut surface uplift showed more fecal attachment on the lamina propria surface, and myolayer integrity after clean the fecal (Fig1c), The final pathology of the surface bulge suggested hyperplasia (Fig1d). Patients were discharged with relieved lower abdominal pain. The final diagnosis was submucosal fecalith mimicking a submucosal tumor, eventually leads to chronic appendicitis. Common causes of cecal submucosal tumor include neuroendocrine tumors, lipomas, etc. There was few report about fecalith mimicking a submucosal tumor. ERTA is currently an effective endoscopic method for treating appendicitis combined with fecalith blockage. To our knowledge, this is the first report on a case of cecum submucosal fecalith mimicking a submucosal tumor and was successfully removed using endoscopy.

Abstract
Human infections caused by Pseudomonas citronellolis, an environmental bacterium, are infrequent, with only two cases related to uncommon urinary tract infections and bacteremia reported in recent years. All these cases typically occurred in elderly patients with compromised or decreased immune function. Simultaneously, the epithelial barrier disruption induced by invasive biopsy procedures or gastrointestinal disorders such as gastroenteritis provided a pathway for Pseudomonas citronellolis to infiltrate the organism. In this study, we present the first report of a case where Pseudomonas citronellolis and Escherichia coli were isolated from the inflamed appendix of a patient without underlying conditions. Compared to the Escherichia coli, Pseudomonas citronellolis has never been isolated in patients with appendicitis. We identified the species using MALDI-TOF MS and genetic sequencing. Based on our findings, we highlight the perspective that Pseudomonas citronellolis can colonize the intestines of healthy individuals and may trigger infections like appendicitis.

Abstract
BACKGROUND Secondary peritonitis is a common emergency surgical condition with varying aetiologies managed by surgeons all over the world. One important morbidity associated with it is postoperative surgical site infection (SSI). A better prevention strategy can be instituted if this complication in patients can be correctly predicted. The study aimed to identify factors in patients with peritonitis that have a significant bearing on the development of postoperative SSI. METHOD A total of fifty patients operated on for peritonitis in a period of one year were studied. Factors including age, gender, comorbidities, presenting symptoms, time of presentation, time of intervention, intraoperative findings, duration of surgery, and postoperative SSI were noted. Chi-square, Fisher's exact test and Student's t-test were used to test for association where appropriate and a p-value of < 0.05 was considered statistically significant. RESULTS Peritonitis was most commonly due to a ruptured appendix (46%) followed by perforated peptic ulcer disease (42%). The incidence of SSI was 44%. For the patients that developed SSI, the lowest rate was observed in cases of ruptured appendix (39.1%) and the highest in perforated gastric ulcer (64.3%) which was closely followed by perforated duodenal ulcer (57.1%). The association between the time of presentation and the occurrence of SSI was statistically significant (p = 0.028). CONCLUSION The SSI rate (44%) from peritonitis in our centre was quite high and the time of presentation played a crucial role. Prevention strategies focusing on predictors of SSI is necessary to reduce the rate of SSI in our setting.

Abstract
BACKGROUND Data from the National Health Expenditure Accounts have shown a steady increase in healthcare cost paralleled by availability of laboratory tests. Resource utilization is a top priority for reducing health care costs. We hypothesized that routine post-operative laboratory utilization unnecessarily increases costs and healthcare system burden in acute appendicitis (AA) management. METHODS A retrospective cohort of patients with uncomplicated AA 2016-2020 were identified. Clinical variables, demographics, lab usage, interventions, and costs were collected. RESULTS A total of 3711 patients with uncomplicated AA were identified. Total costs of labs ($289,505, 99.56%) and repletions ($1287.63, 0.44%) were $290,792.63. Increased LOS was associated with lab utilization in multivariable modeling, increasing costs by $837,602 or 472.12 per patient. CONCLUSIONS In our patient population, post-operative labs resulted in increased costs without discernible impact on clinical course. Routine post-operative laboratory testing should be re-evaluated in patients with minimal comorbidities as this likely increases cost without adding value.

Abstract
BACKGROUND Superior mesenteric artery (SMA) aneurysms account for about 5.5% of all visceral aneurysms, and are most commonly secondary to infectious causes or dissection. They tend to expand and rupture. Here, we present our successful diagnosis and treatment of a 41-year-old man with asymptomatic coeliac trunk stenosis, in whom the large aneurysm of the branch of the SMA developed in a very short time after conservative treatment of plastron appendicitis. CASE REPORT A 41-year-old man was diagnosed with plastron appendicitis during abdomen ultrasound (US) examination. Following 2 weeks of conservative treatment with intravenous antibiotic therapy, complete resolution of symptoms was obtained and confirmed in the computed tomography (CT) scan, and no other pathologies were diagnosed. Three weeks later, during the US examination, a 33-mm aneurysm of the branch of the SMA was diagnosed. The patient was admitted to the Vascular Surgery Department, where a critical stenosis of the coeliac trunk secondary to the compression by median arcuate ligament and a 33-mm true visceral aneurysm of one of the branches of the SMA were diagnosed. Successful treatment of the aneurysm was performed. Surgical decompression of the coeliac trunk and subsequent elective endovascular embolization of the SMA aneurysm with angioplasty of the coeliac trunk were performed. The postoperative period was uneventful and the patient was released from the hospital and remains asymptomatic. CONCLUSIONS Visceral artery aneurysm can form very quickly. In some of the aneurysms, a combination of open surgical and endovascular methods should be performed.

Abstract
INTRODUCTION Scientific literature regarding the characterization of lymphocyte subpopulations of the cecal appendix is sparse, with few precedents limited to immunohistochemical techniques. METHODS We conducted a prospective pilot study to characterize lymphocyte subpopulations of the cecal appendix in children. Participants were divided into three groups: (1) patients without histological acute appendiceal inflammation, (2) patients with histological uncomplicated acute appendicitis, and (3) patients with histological complicated acute appendicitis (gangrenous, perforated). A fresh sample of the base of the appendix was taken from all patients and a flow cytometric study was performed. Quantitative variables were compared using Kruskal-Wallis test and Mann-Whitney U test. RESULTS This study included 57 patients divided into Group 1 (n = 5), Group 2 (n = 37), and Group 3 (n = 15). Median values (IQR) of the percentage of B-lymphocytes were 67.8 [66.8-68.1] in group 1, 61.15 [53.74-66.4] in group 2, and 52.1 [33-62.02] in group 3 (p = 0.02). Median values (IQR) of the percentage of NK-lymphocytes were 0.26 [0.2-0.3] in group 1, 0.55 [0.37-0.66] in group 2, and 0.84 [0.35-1.45] in group 3 (p = 0.008). Median values (IQR) of the percentage of T-lymphocytes were 31.9 [31.7-33.1] in group 1, 37.68 [32.15-45.69] in group 2, and 46.9 [37.03-67] in group 3 (p = 0.02). Pair comparisons of groups 2 and 3 also showed significant differences in the percentage of B lymphocytes (p = 0.03) and NK-lymphocytes (p = 0.02). CONCLUSIONS Significant differences in lymphocyte subpopulations were identified according to the histologic grade of the cecal appendix. More specifically, a lower percentage of B-lymphocytes and a higher percentage of T- and NK-lymphocytes were observed in cases of acute appendicitis. These findings must be confirmed and their etiopathogenic, diagnostic, and prognostic implications elucidated in future studies with larger sample sizes.

Abstract
"Bariolith" is defined as the concretion of barium sulfate in the intestine after performing a radiological study with said contrast. Complications derived from the use of barium are exceptional, but appendicitis, intussusception, volvulus, ulceration, ischemia and perforation have been described. We present the case of a 62 years old woman, who underwent a EGD exploration on the 15th of January 2021 as a part of her study for suspected GERD.

Abstract
PURPOSE Appendicitis is a common cause of acute abdominal pain, and treatment with laparoscopy has become increasingly common during the past two decades. Guidelines recommend that normal appendices are removed if operated for suspected acute appendicitis. It is unclear how many patients are affected by this recommendation. The aim of this study was to estimate the rate of negative appendectomies in patients undergoing laparoscopic surgery for suspected acute appendicitis. METHODS This study was reported following the PRISMA 2020 statement. A systematic search was conducted in PubMed and Embase for retrospective or prospective cohort studies (with n ≥ 100) including patients with suspected acute appendicitis. The primary outcome was the histopathologically confirmed negative appendectomy rate after a laparoscopic approach with a 95% confidence interval (CI). We performed subgroup analyses on geographical region, age, sex, and use of preoperative imaging or scoring systems. The risk of bias was assessed using the Newcastle-Ottawa Scale. Certainty of the evidence was assessed using GRADE. RESULTS In total, 74 studies were identified, summing up to 76,688 patients. The negative appendectomy rate varied from 0% to 46% in the included studies (interquartile range 4-20%). The meta-analysis estimated the negative appendectomy rate to be 13% (95% CI 12-14%) with large variations between the individual studies. Sensitivity analyses did not change the estimate. The certainty of evidence by GRADE was moderate due to inconsistency in point estimates. CONCLUSION The overall estimated negative appendectomy rate after laparoscopic surgery was 13% with moderate certainty of evidence. The negative appendectomy rate varied greatly between studies.

Abstract
BACKGROUND the barriers to implement emergency laparoscopy in public teaching hospitals involve issues such as resident learning curves and resource costs and availability. This study was designed to describe the issues facing the implementation of laparoscopic approach for acute appendicitis over 15 years in a single academic center in Brazil. MATERIALS AND METHODS retrospective study of patients undergoing emergency appendectomy from 2004 to 2018. Clinical data were compared to four major actions implemented in the emergency surgical service: minimally invasive surgery training for residents (2007), laparoscopic stump closure using metal clips (2008), 24/7 availability of laparoscopic instruments for emergency surgeries (2010), and third-party contract for maintenance of the laparoscopic instruments and implementation of polymeric clips for stump closure (2013). We evaluated the increase in laparoscopic appendectomy after the implementation of those major changes. RESULTS we identified 1168 appendectomies during the study period, of which 691 (59%), 465 (40%), and 12 (1%) were open, laparoscopic, and converted, respectively. The implementation of the major changes since 2004 resulted in an increase of laparoscopic appendectomies from 11% in 2007 to 80% in 2016. These actions were decisive in the widespread use of laparoscopy for acute appendicitis (p<0.001). The standardization of the hem-o-lok clip in the treatment of the appendiceal stump made the procedure more feasible, reducing the surgical time using laparoscopic access and increasing the team's adherence, so that this became the route of choice in about 85% of cases in the period from 2014 to 2018, 80% performed by 3rd year resident physicians. No intraoperative complications were noted related to laparoscopic access, even in more complicated appendicitis. There was no mortality reported, no reoperations or readmissions to hospital during a 30-day postoperative period. CONCLUSION the development of a feasible, reproducible, and safe technical standardization, associated with continuous cost optimization, are the cornerstones for a consistent and viable change in the current practice for appendectomies in middle and lower-income countries.

Abstract
Background Human infection with Enterobius vermicularis occurs worldwide. The most common clinical manifestation of a pinworm infection is an itchy anal region. This parasite is incidentally found in appendicitis. This study aims to characterize and genotype this parasite from different samples inferred by mt-DNA. Methods Forty appendectomies for acute clinical appendicitis, 40 positive scotch-tape samples, and 10 adult females worm isolated from patients. Genetic differentiation, haplotype differences, and isolates population structure were analyzed based on the cytochrome c oxidase subunit I (cox1) gene. Results It has been demonstrated that all isolations in the appendectomies specimens are similar, and the genetic difference divergence is seen in adult worm specimens. The neutral indices of the samples did not show a significant difference and show that there is no intra-specific and population distribution diversity. Conclusion Our results show different haplotypes in the B type of E. vermicularis population and add new information about genotyping of these parasites in Iran. In comparison with other studies, intra-specific variation of this parasite from Iran was observed.

Abstract
OBJECTIVE To assess whether different methods for communicating the probability of treatment complications for operative and nonoperative appendicitis treatments result in differences in risk perception. BACKGROUND Surgeons must communicate the probability of treatment complications to patients, and how risks are communicated may impact the accuracy and variability in patient risk perceptions and ultimately their decision making. METHODS A series of online surveys of American adults communicated the probability of complications associated with surgical or antibiotic treatment of acute appendicitis. Probability was communicated with verbal descriptors (eg, "uncommon"), point estimates (eg, "3% risk"), or risk ranges (eg, "1% to 5%"). Respondents then estimated the probability of a complication for a "typical patient with appendicitis." The Fligner-Killeen test of homogeneity of variance was used to compare the variability in respondent risk estimates based on the method of probability communication. RESULTS Among 296 respondents, variance in probability estimates was significantly higher when verbal descriptions were used compared to point estimates ( P < 0.001) or risk ranges ( P < 0.001). Identical verbal descriptors produced meaningfully different risk estimates depending on the complication being described. For example, "common" was perceived as a 45.6% for surgical site infection but 61.7% for antibiotic-associated diarrhea. CONCLUSION Verbal probability descriptors are associated with widely varying and inaccurate perceptions about treatment risks. Surgeons should consider alternative ways to communicate probability during informed consent and shared decision-making discussions.

Abstract
BACKGROUND We established reference intervals for research parameters of complete blood cell count and examined their usefulness for diagnosing certain diseases. METHODS Reference intervals for 26 basic and 38 research parameters were established for 3,457 and 1,325 men and 2,742 and 830 women aged 20 - 59 and ≥ 60 years, respectively. Research parameter values for patients with iron deficiency anemia (IDA), appendicitis, sepsis, and myelodysplastic syndromes (MDS) were compared against gender- and age-matched reference values. RESULTS Seven basic and 10 research parameters among men and one research parameter among women required partitioning by age. No partitioning by gender was required. Further, 67% patients with IDA showed micro red blood cell ratio values above the upper reference limits of their corresponding age and gender subgroups; 3% and 5% patients with appendicitis showed immature granulocyte percentages and counts above the upper reference limits, respectively; 12% - 42% of patients with sepsis showed numerous values exceeded their reference limits, and 67% and 100% patients with MDS showed neutrophil cell complexity and structural dispersion values outside their reference ranges, respectively. CONCLUSIONS Overall, < 60% of research parameter values were outside their reference ranges among most patients, indicating their limited diagnostic usefulness.

Abstract
Purpose: E-cigarette, or vaping, product use-associated lung injury (EVALI) is a severe consequence of vaping first described in 2019. Investigating associations between neighborhood-level characteristics and EVALI cases is an important step in identifying at-risk communities to implement future targeted prevention programs. Methods: We retrospectively identified 41 adolescents <19 years hospitalized for treatment for EVALI at Children's Medical Center Dallas from December 2018 to June 2021. Patient ZIP codes were extracted from the electronic medical record and were compared with Dallas area ZIP codes containing no EVALI cases. Socioeconomic status (SES) characteristics were obtained from the 2019 American Community Survey, and they were mapped for ZIP codes using ESRI ArcMap geospatial processing software. A parallel analysis was conducted utilizing data of adolescents hospitalized with appendicitis. Results: Ninety-five percent of our cohort used tetrahydrocannabinol-containing products, and 66% obtained their vaping products from informal sources. EVALI cases were less likely to reside in higher SES ZIP codes as measured by the proportion of the population with at least a high school education (odds ratio [OR]: 0.95, 95% confidence interval [CI]: 0.92-0.99), access to broadband access (OR: 0.95, 95% CI: 0.91-0.99), and private health insurance (OR: 0.97, 95% CI: 0.95-0.99). Alternatively, they were more likely to reside in lower SES ZIP codes as measured by proportion of the population without any health insurance (OR: 1.07, 95% CI: 1.01-1.12). No neighborhood level low SES characteristics were associated with appendicitis hospitalizations. Conclusions: Although small in magnitude, EVALI cases were associated with lower SES ZIP codes but not with vape shop density.

Abstract
OBJECTIVE To analyze the achievements of laparoscopic surgery in the Central Federal District of Russia and outline perspective trends for further application. MATERIAL AND METHODS The study included adult patients with abdominal surgical diseases hospitalized in general surgical departments of the Central Federal District between 2014 and 2021. We analyzed the prevalence of elective and emergency laparoscopic surgeries. Incidence and results of laparoscopic interventions between 2018 and 2021 were estimated considering primary statistical data presented in the annual collections of the Chief Surgeon of the Ministry of Health of Russia «Surgical care in the Russian Federation». RESULTS The absolute number of laparoscopic surgeries in the Central Federal District increased from 23.686 to 80.489 (by 3.4 times) between 2014 and 2021. The annual number of elective laparoscopic surgeries exceeded the number of emergency ones up to 2019. In 2020-2021, this situation changed in favor of emergency abdominal procedures. Laparoscopic surgeries are the most common for in acute cholecystitis (71.06-81.10% of all laparoscopic interventions annually) and acute appendicitis (46.85-55.60%). In 2020 and 2021, the absolute number of laparoscopic appendectomies exceeded the number of laparoscopic cholecystectomies. These values are lower for perforated ulcers (15.44-20.39%) and acute pancreatitis (32.40-36.71%). Laparoscopic operations are rare for acute intestinal obstruction, strangulated hernia and ulcerative gastroduodenal bleeding. In elective surgery, high availability of laparoscopic surgeries was noted in patients with cholelithiasis (89.40-93.78%), hiatal hernia (62.12-77.27%) and adrenal gland diseases (64.23-87.25%). The most intensive increment of availability (by 2.4 times) was noted for inguinal hernia from minimum level (10.98%) in 2018 to 26.00% in 2021. Mortality after some laparoscopic operations decreased in comparison with laparotomy by 12-45 times (2018-2021). However, this aspect and results of laparoscopic surgeries in case of delayed hospitalization require additional study. CONCLUSION Analysis of laparoscopic surgery showed the timeliness of beginning and development of this direction In Russia. The prospect of further development of laparoscopic surgery for abdominal diseases is determined by modern trends. These are increase in the number of laparoscopic operations for acute appendicitis, acute cholecystitis and perforated ulcers, as well as higher number of early (after admission) operations.

Abstract
It has been hypothesized that short appendices increase intraluminal pressure more rapidly and perforate more frequently than long appendices. Two hundred seventy-seven adult patients were retrospectively analyzed and underwent an appendectomy between January 2015 and August 2021. Data extracted from patient records included sex, age, time from admission to operation (hospital interval), weekday or weekend operation time, and operative and pathological findings. Operation was performed on 273 patients, of whom 178 (65.2%) were male and 95 (34.8%) female. The mean age of the male patients was 31.7 ± 08 (range 18-67), and that of the female patients was 38.9 ± 1.4 (range 18-78). Perforation was observed in 57 (20.9%) patients. Sex was not a factor in the development of perforation (P = .95). The mean age of the patients with and without perforation was 40.1 ± 2.2 and 32.7 ± 0.7, respectively. The perforation rate increased with age (P = .003). Appendix lengths were similar in both groups, and length was not a factor in the development of perforation (P = .83). This study found that the development of perforated appendicitis is not related to the length of the appendix. The risk of perforation increased with age.

Abstract
This document focuses on imaging in the adult and pregnant populations with right lower quadrant (RLQ) abdominal pain, including patients with fever and leukocytosis. Appendicitis remains the most common surgical pathology responsible for RLQ abdominal pain in the United States. Other causes of RLQ pain include right colonic diverticulitis, ureteral stone, and infectious enterocolitis. Appropriate imaging in the diagnosis of appendicitis has resulted in decreased negative appendectomy rate from as high as 25% to approximately 1% to 3%. Contrast-enhanced CT remains the primary and most appropriate imaging modality to evaluate this patient population. MRI is approaching CT in sensitivity and specificity as this technology becomes more widely available and utilization increases. Unenhanced MRI and ultrasound remain the diagnostic procedures of choice in the pregnant patient. MRI and ultrasound continue to perform best in the hands of the experts. The ACR Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision process support the systematic analysis of the medical literature from peer-reviewed journals. Established methodology principles such as Grading of Recommendations Assessment, Development, and Evaluation or GRADE are adapted to evaluate the evidence. The RAND/UCLA Appropriateness Method User Manual provides the methodology to determine the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances in which peer-reviewed literature is lacking or equivocal, experts may be the primary evidentiary source available to formulate a recommendation.

Abstract
ObjectivesTo describe the burden of disease and hospitalisation costs in children with common infections using statewide administrative data.MethodsWe analysed hospitalisation prevalence and costs for 10 infections: appendicitis, cellulitis, cervical lymphadenitis, meningitis, osteomyelitis, pneumonia, pyelonephritis, sepsis, septic arthritis, and urinary tract infections in children aged <18 years admitted to hospital within New South Wales, Australia, using an activity-based management administrative dataset over three financial years (1 July 2016-30 June 2019).ResultsAmong 339 077 admissions, 28 748 (8.48%) were coded with one of the 10 infections, associated with a total hospitalisation cost of AUD230 905 190 and a per episode median length-of-stay of 3 bed-days. Pneumonia was the most prevalent coded infection (3.1% [n = 10 524] of all admissions), followed by appendicitis (1.61%; n = 5460), cellulitis (1.22%; n = 4126) and urinary tract infections (0.94%; n = 3193). Eighty per cent of children (n = 22 529) were admitted to a non-paediatric hospital. Mean costs were increased 1.18-fold per additional bed-day, 2.14-fold with paediatric hospital admissions, and 5.49-fold with intensive care unit admissions, which were both also associated with greater total bed-day occupancy. Indigenous children comprised 9.7% of children admitted with these infections, and mean per episode costs, and median bed-days were reduced compared with non-Indigenous children (0.84 [95% CI 0.78, 0.89] and 3 (IQR: 2,5) vs 2 (IQR: 2,4), respectively.ConclusionsInfections in children requiring hospitalisation contributea substantial burden of disease and cost to the community. This varies by infection, facility type, and patient demographics, and this information should be used to inform and prioritise programs to improve care for children.

Abstract
INTRODUCTION/BACKGROUND Laparoscopic surgery is still at its budding phase in low resource countries. The reasons for this include poor financing of the health sector and lack of trained personnel. The aim of this article is to highlight our initial experiences, our challenges in setting up laparoscopic surgery in a private tertiary hospital in rural southwestern Nigeria, and to share our efforts towards alleviating these challenges. METHODOLOGY A retrospective analysis of all patient who had laparoscopic surgery between January 2019 and December 2020 at the Surgery Department of Babcock University Teaching Hospital, Ilisan, Ogun State was carried out. Their sociodemographic, preoperative and intraoperative data along with postoperative records were subjected to descriptive analysis. RESULTS During the period, 19 patients had laparoscopic procedures: 12(63.2%) males and 7 (36.8%) females with age ranging from 4 to 63years. The most common indication for laparoscopic surgery was appendicitis, representing 84.2% of the procedures. Most of the procedures were done on emergency basis (63.1%) while 36.9% were elective procedures. All the procedures were therapeutic though in 21.1% we started with diagnostic intent but intra-operatively we proceed to therapeutic procedure following confirmation of the diagnosis. The duration of the procedures ranged from 40 minutes to 107 minutes with a mean duration of 74.8±19 minutes. No intra or post operative complications were recorded in this cohort of patients. The mean duration of hospital stay was 2 days. CONCLUSION Laparoscopic surgery is safe and feasible in low resource setting. We recommend that centers embarking on laparoscopic surgeries should start with diagnostic procedures and gradually incorporate therapeutic procedures as they improve in proficiency.

Abstract
Objectives To determine the proportions of abdominal US examinations during on-call hours that are negative and that contain an incidentaloma, and to explore temporal changes and determinants. Methods This study included 1615 US examinations that were done during on-call hours at a tertiary care center between 2005 and 2017. Results The total proportion of negative US examinations was 49.2% (795/1615). The total proportion of US examinations with an incidentaloma was 8.0% (130/1615). There were no significant temporal changes in either one of these proportions. The likelihood of a negative US examination was significantly higher when requested by anesthesiology [odds ratio (OR) 2.609, P = 0.011], or when the indication for US was focused on gallbladder and biliary ducts (OR 1.556, P = 0.007), transplant (OR 2.371, P = 0.005), trauma (OR 3.274, P < 0.001), or urolithiasis/postrenal obstruction (OR 3.366, P < 0.001). In contrast, US examinations were significantly less likely to be negative when requested by urology (OR 0.423, P = 0.014), or when the indication for US was acute oncology (OR 0.207, P = 0.045) or appendicitis (OR 0.260, P < 0.001). The likelihood of an incidentaloma on US was significantly higher in older patients (OR 1.020 per year of age increase, P < 0.001) or when the liver was evaluated with US (OR 3.522, P < 0.001). Discussion Nearly 50% of abdominal US examinations during on-call hours are negative, and 8% reveal an incidentaloma. Requesting specialty and indication for US affect the likelihood of a negative examination, and higher patient age and liver evaluations increase the chance of detecting an incidentaloma in this setting. These data may potentially be used to improve clinical reasoning and restrain overutilization of imaging.

Abstract
BACKGROUND AND AIM In middle-aged men, omental torsion (OT) can be a cause of acute abdomen.The right side of the omentum is longer, heavier and more mobile than the left one and, as a consequence, it can twist more easily on its vascular axis. Consequently, OT localization in the lower right quadrant is more frequent, and therefore it can mimic acute appendicitis clinical onset.In most cases, OT is defined as "primary" in the absence of any other underlying pathologies, or, rarely, "secondary", when caused by other intra-abdominal diseases such as inguinal hernia, tumors, cysts or post-surgical scarring. To date, clinical diagnosis of OT still remains a challenging one in a preoperative setting and most cases are diagnosed intraoperatively. If diagnosis is correctly achieved preoperatively by adequate imaging examinations, most patients presenting with OT do not undergo surgery anymore. Such considerations gain importance at the time of COVID 19 pandemic, where a conservative management and an early discharge may be preferred owing to in-hospital morbidity after abdominal surgery whenever surgery may be avoided. METHODS AND RESULTS We present a case of an OT successfully treated in a non-operative manner during COVID-19 outbreak in Norhern Italy and offer a review of the literature that supports such a clinical attitude. Conclusions: OT preoperative diagnosis is challenging and is usually achieved by abdominal CT-scan. The suggested OT initial management is conservative, leaving a surgical approach, preferably by laparoscopy, for the 15% of cases not improving with a non-surgical approach.

Abstract
The prevalence and incidence of neuroendocrine tumors (NETs) are increasing in the pediatric population. This increase can be associated with improved diagnostics and increased detection rates of the disease. We aimed to discuss the clinical and pathological characteristics of patients with this rare disease who were followed and treated at our center.The medical records of children (aged 0-18 years) with NETs of the digestive system, followed up and treated between 2007 and 2020 at Ondokuz Mayis University Faculty of Medicine, were reviewed.Overall, 16 patients (8 girls and 8 boys) were analyzed. Fifteen patients had NETs in the appendix; 14 of these had grade I NETs, and 1 had grade II NETs. No additional surgery was performed except for appendectomy. All patients were in complete remission at the last follow-up (median 38 months). The other patient, a 12-year-old girl, had a primary hepatic neuroendocrine carcinoma (grade III NET). Three cycles of neoadjuvant and adjuvant platinum-based chemotherapy were administered, and right hepatectomy was performed to remove the mass. The patient is being followed-up for approximately 3 years without disease recurrence.Most NETs are observed in adults, and most studies have focused on this population. Unlike adults, increasing awareness of the disease in the pediatric population (especially in cases of acute appendicitis), discovering therapeutic treatments, and sharing experiences are crucial for developing an optimal therapeutic approach for pediatric NETs.

Abstract
Surgeons encounter neutropenic patients through elective or emergency consultation with increasing regularity. As medical management continues to extend the lives of patients with benign hematologic diseases, hematologic malignancies, solid malignancies, or iatrogenic neutropenia, more patients are presenting with infectious complications caused and/or complicated by their neutropenia. This leaves surgeons in the difficult position of managing medically fragile patients with unusual presentations of common disease processes. These patients often fall outside of classical guidelines and treatment pathways. Many studies addressing these issues are retrospective and non-randomized. Here, we review common emergency gastrointestinal surgery scenarios and their management in the setting of a neutropenic patient. While biliary disease, appendicitis, anorectal disease, and perforations will be covered in detail, an extensive appreciation of a patient's medical or oncologic disease course and appropriate utilization of consultants such as interventional radiology, gastroenterology, and hematology is often necessary.

Abstract
Goblet cell carcinoid or carcinoma (GCC) refers to an extremely rare appendiceal tumor usually diagnosed on post-operative histology as an incidental finding. Primary cancers of the vermiform appendix are quite rare, representing less than 1% of all gastrointestinal malignancies. GCCs are considered as a distinct entity of appendiceal tumors, consisting of both epithelial (glandular) and neuroendocrine elements containing goblet cells. This entity tends to be more aggressive than typical carcinoid tumors as it often presents with metastatic disease. Therefore, an early recognition and an appropriate grading is essential. The 5-year overall survival is 14-22% in stage III-IV disease. As a matter of fact, GCC warrants more aggressive surgical and medical (chemotherapy) treatments than typical carcinoid tumors. We, hereby, report a case of a 67-year old male presenting with an acute abdominal obstruction and a severe tenderness predominant in his right lower quadrant, together with an endoscopic and radiological suspect of left colonic malignancy and acute appendicitis. Left hemicolectomy and appendicectomy were performed and pathological specimens revealed a lowgrade adenocarcinoma of the descending colon and a high-grade appendiceal goblet cell carcinoid. Subsequent right hemicolectomy was performed according to the current guidelines. GCCs are more aggressive compared with conventional appendiceal tumors but less aggressive compared with adenocarcinomas and they often present with serosal and mesoappendiceal involvement. The lack of a standardized classification system for GCC and the discrepancies in specific reliable markers are responsible for an insufficient prognostic and predictive value at diagnosis.

Abstract
Sonography is the imaging modality of choice for diagnosing diseases of the female genital tract due to its high resolution, easy availability, low cost and lack of radiation. CT is not advocated for the primary evaluation of the female pelvis. However, with the advent of Multidetector CT (MDCT), females of all ages undergo CT scan of the abdomen and pelvis for myriad non-gynaecological diseases, e.g. subacute intestinal obstruction, abdominal lump, abdominal tuberculosis, appendicitis, ureteric colic, pancreatitis, oncological staging, follow-up, etc. Incidental female genital tract disorders were seen on these scans that are a dilemma for both, the radiologists and the clinicians. The objective of this pictorial review is to characterise the incidentally detected lesions of the female genital tract observed on 64-slice MDCT by correlating with sonography, if necessary, and establishing a clinico-radiological diagnosis. Our aim is to emphasise that the radiologist may be the first person to recognise a gynaecologic disorder and hence can play a significant role in patient management.

Abstract
Enterocolic lymphocytic phlebitis (ELP) is a rare pathology, usually seen in the adult population. The condition affects the venous vasculature of the intestine sparing the arteries and lymphatics. It is commonly identified histologically after surgical resection making the preoperative diagnosis a clinical challenge. As the condition can lead to intestinal ischaemia and necrosis, surgical resection of the affected segment is the treatment of choice. We report the case of a 9-year-old girl who presented with a 2-day history of lower abdominal pain and anorexia. The initial diagnosis of appendicitis was made clinically and the patient underwent a diagnostic laparoscopy . The appendix was macroscopically normal and there were no other obvious intra-abdominal pathologies to account for her presenting complaints . The appendix was removed, as per the preoperative discussion and consent from parents. She recovered well and was discharged home the following day. The histological examination of the appendix demonstrated ELP. We describe this rare clinical entity in a child especially in view of the scarce published literature in the paediatric population.

Abstract
BACKGROUND Illness complications are condition-specific adverse outcomes. Detecting complications of pediatric illness in administrative data would facilitate widespread quality measurement, however the accuracy of such detection is unclear. METHODS We conducted a cross-sectional study of patients visiting a large pediatric emergency department. We analyzed those <22 years old from 2012 to 2019 with 1 of 14 serious conditions: appendicitis, bacterial meningitis, diabetic ketoacidosis (DKA), empyema, encephalitis, intussusception, mastoiditis, myocarditis, orbital cellulitis, ovarian torsion, sepsis, septic arthritis, stroke, and testicular torsion. We applied a method using disposition, diagnosis codes, and procedure codes to identify complications. The automated determination was compared with the criterion standard of manual health record review by using positive predictive values (PPVs) and negative predictive values (NPVs). Interrater reliability of manual reviews used a κ. RESULTS We analyzed 1534 encounters. PPVs and NPVs for complications were >80% for 8 of 14 conditions: appendicitis, bacterial meningitis, intussusception, mastoiditis, myocarditis, orbital cellulitis, sepsis, and testicular torsion. Lower PPVs for complications were observed for DKA (57%), empyema (53%), encephalitis (78%), ovarian torsion (21%), and septic arthritis (64%). A lower NPV was observed in stroke (68%). The κ between reviewers was 0.88. CONCLUSIONS An automated method to measure complications by using administrative data can detect complications in appendicitis, bacterial meningitis, intussusception, mastoiditis, myocarditis, orbital cellulitis, sepsis, and testicular torsion. For DKA, empyema, encephalitis, ovarian torsion, septic arthritis, and stroke, the tool may be used to screen for complicated cases that may subsequently undergo manual review.

Abstract
Laparoscopy is a procedure that ultimately reduces hospital stay time and speeds up post-operative recovery. It is mainly performed in high-income countries but its implementation in many low- and middle-income countries (LMICs) is increasing. However, no aggregate data exist regarding the outcomes of this procedure in resource-limited settings. We retrospectively reviewed all cases of laparoscopy recorded from January 2007 to March 2017 at the Department of Surgery of Beira to assess the related outcomes. Moreover, we performed a systematic review of the laparoscopic practices and outcomes in low-income countries. Data from the Department of Surgery of Beira identified 363 laparoscopic procedures, mainly relating to gynecological diseases, cholelithiasis, and appendicectomy with only a 1.6% complication rate (6 cases) and a 1.9% conversion rate (7 cases) to open surgery. The systematic review showed a pooled risk of overall complications significantly lower in laparoscopic vs. open appendicectomy (OR = 0.43; 95% CI 0.19-0.97; I2 = 85.7%) and a significantly lower risk of infection (OR = 0.53; 95% CI 0.43-0.65; I2 = 0.00%). The pooled SMD in operation duration in laparoscopic vs. open appendectomy was 0.58 (95% CI -0.00; 1.15; I2 = 96.52), while the pooled SMD in hospitalization days was -1.35 (95% CI -1.87; -0.82; I2 = 96.41). Laparoscopy is an expensive procedure to adopt as it requires new equipment and specialized trained health workers. However, it could reduce post-operative costs and complications, especially in terms of infections. It is crucial to increase its accessibility, acceptability, and quality particularly in LMICs, especially during this COVID-19 era when the reduction of patient hospitalization is essential.

Abstract
BACKGROUND Patients with paraplegia develop syndrome-specific complications relevant to visceral surgery, which occur in the context of the acute spinal shock or as a consequence of the progressive neurogenic bowel dysfunction (NBD) with the formation of an elongated colon and/or megacolon. Moreover, acute abdominal emergencies, such as acute appendicitis, cholecystitis, diverticulitis and ileus images, pose particular challenges for the clinician when the clinical signs are atypical or even absent. The expansion of indications for obesity surgery to include patients with a paraplegic syndrome, whose independence and quality of life can be impaired due to the restricted mobility, especially by obesity, is becoming increasingly more important. OBJECTIVE This article provides an overview of the special requirements and aspects in the treatment of this special patient collective and to show the evidence of paraplegia-specific visceral surgery treatment. MATERIAL AND METHODS Targeted literature search in Medline and Cochrane library (German and English, 1985-2020). RESULTS AND CONCLUSION The clinical treatment of paraplegic patients requires in-depth knowledge of the pathophysiological changes at the different height of the paraplegia (upper versus lower motor neuron) and the phase of the disease (spinal shock versus long-term course). Missing or atypical clinical symptoms of acute diseases delay a quick diagnosis and make early diagnosis essential. The evidence for surgical treatment of the acute and chronic consequences of NBD is based on small retrospective series and case reports, as is that for special indications such as obesity surgery.

Abstract
An 84-year-old woman with a chief complaint of right lower abdominal pain was admitted to our hospital in November 20XX. Abdominal CT scan revealed a 9.6×4.1 cm diameter low density area proximal to the 13 mm diameter appendix, which led to perforated appendicitis with a huge abscess. The patient underwent an open appendectomy with partial cecum resection. The appendix was found to be twisted by 540°. The pathological diagnosis was low-grade appendiceal mucinous neoplasm(LAMN). Recent research has found that the use of laparoscopic surgery for the treatment of LAMN has been increasing. Appropriate surgical intervention should be considered for LAMN because it is a borderline malignancy. Careful treatment with laparoscopic surgery might be considered as one of the treatment options for LAMN. We hope to accumulate more cases of LAMN to confirm our results.

Abstract
BACKGROUND Treatment methods for appendiceal-colonic fistulas differ greatly depending on whether lesions are benign or malignant. If the tumor is malignant, appendectomy with lymph node resection (ileocecal resection or right hemicolectomy) should be performed. There is no consensus on the method of surgery for organs infiltrated by appendiceal cancer. Furthermore, there are no reported laparoscopic cases that could be prevented from over-surgery by laparoscopy examination or rapid intraoperative pathological examination. CASE REPORT A 76-year-old man presented with positive fecal occult blood. Lower endoscopy revealed a 10-mm tumor in the rectosigmoid colon accompanied by white moss. A biopsy showed inflammatory granulation and no malignancy. Fluorodeoxyglucose-positron emission tomography showed highly increased accumulation at the tip of the appendix, and the standardized uptake value max was 7.3. We suspected a benign lesion rather than appendiceal cancer with infiltration into the rectosigmoid colon; therefore, we performed laparoscopic appendectomy and wedge-shaped resection of the rectum of the sigmoid colon. An intraoperative rapid pathological examination showed no appearance of malignancy; therefore, additional resection was omitted, and an ileostomy was created in the right lower quadrant. A permanent pathological examination showed complicated appendicitis, with no appearance of malignancy. The ileostomy was closed on postoperative day 25, and the patient was discharged on postoperative day 32. CONCLUSIONS In cases where there is difficulty in identifying whether the appendiceal-colonic fistula lesion is benign or malignant, laparoscopy and intraoperative rapid pathological examination may be useful in avoiding excessive treatment.

Abstract
INTRODUCTION The difference in outcome between right (RCD) and left colonic diverticulitis (LCD) is not well established. The aim of this study was to analyse the presentation and surgical outcome of RCD versus left-sided disease following emergency surgery. METHOD We conducted a retrospective review of patients presenting with acute diverticulitis over a 10-year period from 2004 to 2014 to a tertiary unit. Patient demographics, Hinchey classification, need for emergency surgery, perioperative outcome and recurrence were evaluated. RESULTS In total 360 patients presented with acute diverticulitis, 218 (61%) were right-sided and 142 (39%) were left-sided. The mean age (57 yrs vs 68 yrs) and median length of stay (4 days vs 5 days) were significantly less in RCD (p < 0.001). The need for emergency surgery was similar between RCD and LCD (30.7% vs 23.2%, p = 0.12). Sixty-seven (31%) patients with RCD required emergency surgery, 42 (62.7%) of these were based on a presumptive diagnosis of appendicitis and underwent laparoscopic appendicectomy only. Operative morbidity (10.4% vs 51.5%, p < 0.001) and mortality were significantly higher in LCD (1.5% v 15.2%, p = 0.007). Subgroup analysis of non-appendicectomy, RCD patients, showed LCD were more likely to require surgery (11.5% vs 23.2%, p = 0.003). There was no difference in recurrence (p = 0.6). CONCLUSION Right colonic diverticulitis patients are younger and disease course is more benign compared to LCD. Presentation can be confused with appendicitis without proper imaging. In the rare cases where emergency surgery is required, RCD is associated with a lower operative morbidity and mortality compared to left-sided disease.

Abstract
Background: Appendiceal diverticular disease (ADD) is typically a histological diagnosis. Our paper aims to investigate the implications of ADD compared to acute appendicitis (AA). Methods: We conducted a retrospective data collection of patients who had undergone an appen dicectomy in three tertiary hospitals across Western Australia between 2009-2019 and included patients with histopathological diagnoses of ADD and AA. Results: Thirty-seven patients with ADD and forty with AA were included. The mean age in the ADD group was significantly older (p 0.001) at 50.1 compared to the AA group (37.3). The mean white cell count (WCC) in the ADD group was lower than the AA group (11x109/L vs. 13.3x109/L, p 0.001), whereas the C-Reactive Protein (CRP) level was greater, although not statistically significant. The ADD group had a greater risk of major surgery (p 0.05) and complications such as appendiceal perforation and appendiceal mass (p 0.05). Post-operative colonoscopy also demon strated a higher incidence of polyps in patients with ADD (19% vs. 2.5%, p 0.001). Conclusion: ADD frequently presents with clinical features indiscernible from AA. Our study demonstrates that ADD is associated with higher rates of appendiceal perforation, polyps and malignancy. We recommend that patients with ADD be advised to have a colonoscopy post-opera tively to rule out underlying malignancy.

Abstract
Primary appendiceal cancer is rare and most commonly found incidentally on a surgical specimen after appendectomy for acute appendicitis. This small organ gives rise to different subtypes which are histological and biological distinct. Historically the classification of these tumors has been confusing because of the different nomenclature that is used. This review has broadly classified them into four subgroups: colonic-type adenocarcinoma, mucinous neoplasm, goblet cell carcinoma and neuroendocrine neoplasm. Signet ring cells is not considered as a distinct subgroup but as a histologic feature that can be present in colonic-type adenocarcinoma and mucinous neoplasms. As staging and management of appendiceal tumors depend on these subtypes, an adequate classification of them is important. This review aimed to give an overview of the epidemiology, grading and staging, management and prognosis of these neoplasms. Despite its rarety, specific staging systems and treatment guidelines exist for some subtypes. For other subtypes staging systems and management is extrapolised from colorectal cancer because of the lack of randomised, prospective trials.
