Review
To review studies examining the appendiceal microbiota and microbial changes in acute appendicitis. After a systematic literature search, 11 studies examining the appendiceal microbiota (414 samples) using non-culture-based methods were included. The appendiceal microbiota showed decreased α-diversity compared with fecal microbiota. Inflamed and uninflamed appendices showed differences in β-diversity, and there was an increased abundance of oral-associated bacteria in inflamed versus uninflamed appendices. The appendiceal microbiota exhibits lower α-diversity than the fecal microbiota, with an increased abundance of oral-associated bacteria. Compared with uninflamed appendices, the appendix microbiota in acute appendicitis also showed increased abundance of oral-associated bacteria, but no bacterial profile unique to either complicated or uncomplicated appendicitis was found.

Review
Surgical procedures for the symptomatic removal of the gallbladder and the vermiform appendix have been posited to adversely shift the assemblage of the intestinal microbiome increasing the risk of disease. The associated mechanisms have been linked with dysbiosis of the gut microbiota. Cholecystectomy causes changes of bile acid compositions and bile secretion patterns as bile acids interact with the intestinal microbiota in a bidirectional capacity. An appendectomy precludes the further recolonization of the proximal colon with a commensal biofilm that could maintain a stable intestinal microbiome. Epidemiological studies indicate that there is an increased risk of disease rather than causality following a cholecystectomy and appendectomy. This narrative review summarizes studies that report on the role that bile salts and the appendix, contribute to the assemblage of the intestinal microbiome in health and disease.

Review
The aim of this review is to focus light on the history of the human vermiform appendix from the morphological, anatomical, surgical, classification of the origin, types, blood supply aspects in order to understand the real function and summarized this information that positively impacts the clinical decision in case of appendicitis, the most popular surgical condition. Although the characteristic features of the normal and diseased appendix had been reported for many previous centuries, it was still the most common challenge facing every single day in the operation room. The appendectomy, the commonest surgical emergency procedure, may cause little confusion for the surgeons due to highly variable situations of inside the abdominal cavity. However, the recent imaging techniques have increased the surgeon's ability for crucial diagnosis of the diseased appendix. Besides the above-mentioned criteria, with its clinical features diagnosis and management, the author was deeply searched in many scientific databases including EMBASE, Cochrane Library, PubMed, Pubmed Central (PMC), Medline, Web of Science, and Scopus.

INTRODUCTION
Appendix muscle bands (AMB) develop from the appendix muscle layer into the mesoappendix. There are few recent publications on this forgotten entity. The objectives of this study were to assess the morphological features of AMB as detected at microscopy examination of appendectomy specimens.
METHODS
Sixty-six cases of AMB as detected on appendectomy specimens were assessed for microscopy features on routine hematoxilin and eosin stained tissue slides. The morphological features were analyzed with regard to the main clinico-pathological parameters.
RESULTS
AMBs were multiple in 35 cases. Most AMBs were located between the tip and cecal limit, 7 at the tip, and 1 at the cecal limit of the appendectomy specimen. Associated appendix lesions were: acute appendicitis, neuroma, mesoappendix cyst, muscle hiatus, and diverticulae (60,6,2,45, and 1, respectively). In 24 appendices, the AMB developed from the perihiatus muscle. Two microscopy types of AMBs were detected: muscle-AMB and mesoappendix-AMB.
CONCLUSION
AMB may be detected incidentally at microscopy of appendectomy specimens. Acute appendicitis was associated in most cases, independently on the microscopy type of AMB. Appendix abnormalities as neuroma, mesoappendix cyst, muscle hiatus, and diverticulae can be associated to AMBs.
