Сибирский научный медицинский журнал
Vermiform appendix is the only organ in the body that has no constant anatomical position. It is so named because of its worm like appearance. Most common surgical cause of abdominal pain is appendicitis; its diagnosis is affected by anatomical variations of the vermiform appendix, because this is the most variable abdominal organ in terms of position and organ relations. Aim of the study was to examine anatomical features and different positions of the vermiform appendix in human cadavers. Material and methods. This study was carried on 45 human cadavers irrespective of sex and age from the Department of Anatomy at Andhra Pradesh over a period of 12 months. Results. Mean length of appendix was found to be 3.98 ± 1.27 cm. Mean outer girth was 2.17 ± 0.26 cm. Mean distance of vermiform appendix from ileocaecal junction was found to be 2.11 ± 0.43 cm. Commonest position was retrocaecal (44 %), followed by pelvic (21 %), postileal (9 %), subcaecal (13 %) and midinguinal (10 %). Conclusions. Variations in position of vermiform appendix will help the surgeons to make a diagnosis of appendicitis and aware about appendiceal rupture.
A study on various positions of vermiform appendix in adult human cadavers
IP Innovative Publication Pvt. Ltd., 2019
Introduction: Aim was to know various positions of Vermiform appendix. Acute appendicitis is the most common general surgrical emergency. Obstruction of its lumen is the most common cause of acute appendicitis. The severity of appendicitis along with its various positions may lead to different clinical presentations. Knowledge of positions of appendix is essential for surgeons and physicians to arrive an accurate diagnosis and proper management of appendicitis. Materials and Methods: This study was carried out in fifty adult human cadavers in the Institute of anatomy, Madras Medical College over a period of one year from 2017-2018. The appendix was examined in all the specimens to recognise its various positions. Result: In the present study, Vermiform appendix was retrocaecal in 31 specimens, then pelvic in 16 specimens. The least common postions were post ileal in 2 specimens and subcaecal in 1 specimen. Conclusion: The knowledge of various anatomical positions of appendix is must for surgeons to make proper diagnosis and management of various clinical and pathological conditions related to appendix.

Different Positions of Vermiform Appendix in Human Cadavers: A Cross-sectional Study
INTERNATIONAL JOURNAL OF ANATOMY RADIOLOGY AND SURGERY
Introduction: The vermiform appendix is a wormlike tube situated in the right iliac fossa. It arises from the posteromedial cecal wall, 2 cm or less below the end of the ileum and suspended by a peritoneal fold known as meso appendix. Position of the appendix influences its mobility. Most common position of appendix has been reported to be retrocecal followed by pelvic position. But there are other variable positions also reported by many. Aim: To study the anatomical variations of the positions of vermiform appendix in human cadavers. Materials and Methods: This was a descriptive cross-sectional study which was carried out in the Department of Anatomy, Assam Medical College, Dibrugarh, Assam, India, from June 2020 to May 2021. Total 14 adult cadavers and 66 new born cadavers were included in the study. All the cadavers were dissected and abdominal cavity was explored. The position of the appendix was then noted in all specimens. Results: In most of the cases the position of vermifo...

Journal of Coloproctology, 2015
Objective Evaluation of the frequency of the relative positions and length of vermiform appendix in a group of corpses examined by the authors. Method Dissection of 377 adult cadavers autopsied. Results and conclusions Retrocecal: 43.5%; subcecal: 24.4% post-ileal: 14.3%, pelvic: 9.3%; paracecal: 5.8%; and pre-ileal appendices: 2.4%, other positions: 0.27%, mean length: 11.4 cm.
In vivo location of the human vermiform appendix
Clinical Anatomy, 1994
The anatomic position of the appendiceal tip is cited in many surgical and anatomical texts as being fixed in the retrocecal position in as many as two-thirds of cases studied. The reference most often quoted to support this observation is Wakeley (1933), but this frequency did not correspond to the clinical experience of the surgical staff at the authors' institution. Accordingly, a prospective survey of the in vivo location of the vermiform appendix was undertaken over a 6-month period. T h e results demonstrated that the retrocecal position was indeed the most common location, but occurred in only 33% of instances. This observation may encourage greater utilization of laparoscopic appendectomy, since it suggests that retroperitoneal dissection will not be necessary to locate the appendiceal tip in the majority of cases.

Introduction: the Vermiform Appendix (VA) is a highly variable organ, being an enigma for the surgeon regarding its position, size and symptomatology. Rapid and accurate diagnosis for adequate treatment of acute appendicitis not only depends on the symptoms, but also on the knowledge of variations in its anatomical position. Objective: to determine the occurrence of the anatomical position of the VA in fresh cadavers, its relationship with the mesoappendix and morphometry. Material and method: the Vermiform Appendages (VAs) of 50 fresh cadavers were examined, the morphological aspects and morphometry of the VAs were studied, such as: position, length and diameter of the appendix, in addition to the length of the mesoappendix and whether it occupied the entire length of the appendix length. Morphometric data were performed with a digital caliper with a precision of 0.01 mm. Result: of the 50 cadavers autopsied during the study, 44 (88%) were male and six (12%) were female. Age ranged...
The Anatomical Position of Appendix in Iranian Cadavers
Vermiform appendix is different in terms of anatomical position, length and mesoappendix. Knowing the anatomical position of vermiform appendix is important for the surgeons in terms of diagnosis and management. The aim of this study is analysis of length, anatomical position and mesoappendix of vermiform appendix. Methods: This is a cross-sectional study on the 400 randomly selected cadavers (306 male and 94 female) who have been referred to the autopsy hall of legal medicine organization of Tehran province to be autopsied between March 21, 2010 and March, 2011. The cause of death was very heterogeneous among autopsied cadavers. Results: According to our results the anatomical positions were pelvic, subcecal, retroileal, retrocaecal, ectopic and preileal in 55.8%, 19%, 12.5%, 7%, 4.2% and 1.5% respectively. The mean length of vermiform appendix was 91.2 mm and 80.3 mm in men and women, respectively. Mesoappendix was complete in 79.5% and incomplete in 20.5%. No association was seen between sex and anatomical position of vermiform appendix. Conclusion: Anterior anatomical position was the most frequent vermiform appendix position in our population which is in discrepancy with most of the reports from western countries. It might be possible that factors such as race, geographical regions and nutritional regiment play roles in determining the position of vermiform appendix.
Study of Variations in Position of Appendix in 100 Operated Case of Appendicitis

Introduction:-Appendix is a wormlike structure arises from posteromedial wall of the cecum, about 2 cm below the ileocecal valve. Though a remarkably constant structure, the appendix is occasionally subject to the extremes of variation, Signs and symptoms may show varying degree of discrepancy depending on position of the appendix. The aim of our study is to determine the position of the appendix in a group of patients examined by the authors. Results:-The positions of the appendix found were as follow :-retrocecal: 66% , pelvic: 27%, post-ileal: 3% , subcecal: 2% , paracecal: 1% , pre-ileal: 1%. Discussion:-In our study retrocecal is the most common position, followed by pelvic> post-ileal>subcecal>paracecal>pre-ileal. The result of our study is correlating with some study in which retrocecal position is most common and contradicting with some study in which pelvic position is most common (Table 1).symptom and sign is different in various position and mimics other condition which leads to misdiagnosis. In the subcecal position, the appendix is intraperitoneal if inflamed, it can cause diffuse peritonitis. Thus, this position can be regarded as the most susceptible to complications. In pelvic position appendicitis may mimics with cystitis. In pre or post ileal position may irritate intestine and mimics gastroenteritis. Conclusion:-After the study strong association has been found between hidden locations of the appendix and the development of an advanced appendicitis, which results in longer hospital stay and high incidence of gangrene and perforation.
According to the results, the anatomical positions of the appendix were pelvic, subcecal, retroileal, retrocecal, ectopic, and preileal in 55.8%, 19%, 12.5%, 7%, 4.2%, and 1.5% of the bodies, respectively. The mean length of vermiform appendix was 91.2 mm and 80.3 mm in men and women, respectively. Mesoappendix was complete in 79.5% of the bodies. No association was found between sex and anatomical position of vermiform appendix. Anterior anatomical position was the most common position for vermiform appendix. It is inconsistent with most related reports from western countries. It might be possible that some factors, such as race, geographical changes, and dietary habits, play roles in determining the position of vermiform appendix.
