ABSTRACT
Background: Head of appendix can be placed in different situations but the base of appendix is connected to thececum. The variation in the situations is classified into six locations: retrocecal, pelvic, subcecal, paraileal,retroileal, and subhepatic.Objectives: To study the variation in the anatomical features, length & external diameter of appendix and itsassociation with age and sex in people in the Gujarat.Material and method: This study was conducted on total 200 cases taken from dissection laboratory of theanatomy department of three different medical college of Ahmedabad during 2009 to 2012. Length of vermiformappendix was measured by nylon thread from root to tip of appendix. Thread’s length was measured by verniercaliper. External diameter was measured by vernier caliper at a maximum external diameter of the appendix.Result: anatomical locations of the appendix which were as follows: retrocecal in 111 individuals (55.5%),pelvic in 47 individuals (23.5%), retroileal in 18 individuals (9.0%), subcaecal in 13 individuals (6.5%), paracaecalin 10 individual (5.0%), and subhepatic in 1 individual (0.5%). a significant association was found between theappendix length and different age groups. The average length of appendix was 55 mm for men and 51 mm forwomen. The average external diameter of appendix was 73 mm for men and 65 mm for women.Conclusion:Retrocaecal appendix has symptoms of upper urinary tract infection, due to irritation of the adjacentureter. In pelvic position pain may be felt when the thigh is flexed and medially rotated, because the obturatorinternus is stretched. Pelvic appendix may irritate the bladder or rectum causing suprapubic pain, pain withurination, or feeling the need to defecate.
ABSTRACT
Background: The aim of present study is to note the prevalence of various positions of appendix along with its length and extent of meso-appendix in two genders and different age groups in patients of acute appendicitis from Bundelkhand region. Method: This observational study was carried out on 100 patients belonging from Bundelkhand region of India, suffering from Acute Appendicitis. Position of appendix and extent of meso-appendix observed carefully followed by measurement of length of appendix from base to tip. All the findings were tabulated and inferences were drawn followed by statistical comparison using chi-square test and t-test with p value <0.05 considered as significant. Result: Highest prevalence of acute appendicitis was found in the age group of 11-19 years age group. Highest prevalent position amongst all appendix position was retrocaecal in both genders and in all age groups followed by pelvic position. The length of appendix ranged from 37 mm to 120 mm in males with an average of 78.9 ± 18.1 mm, while its length ranged from 38 mm to 96 mm in females with an average of 65.5 ± 17.5 mm. Average length of the appendix was found 13.4 mm higher in males as compared to females. In 90% of cases in this study, mesoappendix extended to its full extent, whereas in 10% cases it failed to reach its tip. Conclusion: Findings in this study show subtle differences in length, position and extent of mesoappendix from other studies from other regions. Such studies are needed to be conducted in all geographical regions with as much possible number of observations.
ABSTRACT
Background: The mesentery of the appendix extends almost to the appendicular tip along the whole tube or may not be to the tip. The mesoappendix has a free border which carries the blood supply to the organ. Failure of the mesoappendix to reach the tip probably reduces the vascularization of the tip of the organ making it more liable to become gangrenous and hence early perforation occurs during inflammation. Objective: This cross sectional study was carried out to advance our knowledge regarding the extent of mesoappendix in Bangladeshi people and also to find out the variations in the anatomical positions of the vermiform appendix in Bangladeshi population and their distribution according to the sex. Methods: A total of 100 (60 male and 40 female) specimens of vermiform appendix were collected of different age and sex during postmortem examination in the morgue of Mymensingh Medical College from July 2006 to June 2007. Data was collected by convenient sampling technique. Results: In this study pelvic position of the vermiform appendix were common in both sexes. The two thirds extension of mesoappendix was found in 45% cases where as in pelvic position it was 26 (14 male and 12 female) cases. Half and whole extension of mesoappendix were found in 31% and 24% cases respectively. Among half extension of mesoappendix, retrocaecal position were found to be more (12) than other positions. In whole extension of vermiform appendix pelvic position were found to be common (16) than others. Conclusion: This study provides certain basic information of extent of mesoappendix of vermiform appendix of Bangladeshi population which is responsible for vascularization of the organ and severity during inflammation.
ABSTRACT
A primary malignant fibrous histiocytoma (MFH) is a soft tissue sarcoma of mesenchymal origin. A primary MFH occurs most commonly in the extremities and the trunk in adults, but rarely in the alimentary tract. We report a case of MFH of the mesoappendix in a 49-year-old male who presented with a periappendiceal abscess. To the best of our knowledge, this is the first report of MFH in the large intestinal tract, including the appendix, in Korea. The patient recovered well after a right hemicolectomy and was given adjuvant chemotherapy.
