Bakar SM, Shamim M, Salam A, Sultana SA

Ir J Med Sci, 2016 Feb;185(1):249-57.
PMID: 25894278 DOI: 10.1007/s11845-015-1287-4

BACKGROUND: The anatomy of the vermiform appendix shows variations in its macroscopic dimensions and microscopic features, some of which have potentials of influencing the clinical aspects of the appendix.
AIM: The aim of this study was to find out some microscopic features of appendix and evaluate the correlation between the microscopic features of the appendix and the age of the subjects and to determine whether these findings should influence the clinical implications of appendix.
METHODS: In this cross-sectional observational study, thirty adult males' (age from 18 to 67 years) postmortem appendices and adnexa from Bangladeshi victims of road traffic accidents were sectioned at the base, midzone and tip stained with H+E stain and examined under microscope. Measurements were taken at the base, at the midzone and at the tip of the appendix, and the mean of the three measurements was considered as the overall value.
RESULTS: The overall number of mucosal glands in a section ranged from 42.33 to 130.00 and the number of the germinal centres varied between 2.33 and 10.00. The overall luminal diameter ranged between 1764.58 and 3208.33 µm. The overall luminal diameter in more than 52 % of cases was between 2700.00 and 3299.99 µm with a median value of 2750 µm.
CONCLUSION: The overall number of mucosal glands showed a tendency towards a positive correlation with age. The overall luminal diameter and the overall number of germinal centres showed a tendency towards a negative correlation with the age. However, none of the tendencies of correlation reached statistically any significant level.

Appendicitis has a worldwide prevalence and affects all age groups. The aetiology of acute appendicitis is still much debated, many factors have been implicated. The pathology is likely to be due to obstruction of the lumen of the appendix. Parasites, both helminths and protozoa have been suggested to be the cause of acute appendicitis. Studies have demonstrated that parasites are present in the appendix specimens removed from surgery methods.

Rare complication of appendix: small bowel gangrene caused by the appendicular knot

Mohana RT, Zainal AA

Med J Malaysia, 2017 12;72(6):370-371.
PMID: 29308777 MyJurnal

Intestinal knot formation was first described by Riverius in 16th century and later by Rokitansky in 1836. We report a very rare cause of small bowel gangrene caused by appendiceal knotting on to the ileum in a previously healthy mid aged lady. Patient underwent laparatomy and right hemicolectomy and primary anastomosis. The intra operative findings were the appendix was twisting (knotting) the small bowel about 40cm from the terminal ileum and causing gangrene to the segment of small bowel. Appendicitis is a common condition and management is usually straightforward. However we must be aware of rare complications which may arise that require a change from the standard treatment of acute appendicitis.

Acute appendicitis is an infrequent yet the commonest surgical emergency in pregnancy occurring in about 1:1500 pregnancies. The classical abdominal pain in the right lower quadrant of the abdomen is the only reliable clinical sign. Delay in diagnosis is attributed to presence of symptoms commonly seen in pregnancy like nausea and vomiting and difficulty in localizing abdominal pain due to displacement of the appendix with advancing gestation. Perforated appendix and generalized peritonitis impacts adversely on pregnancy contributing to increases in miscarriage, pre-term delivery, fetal loss and even maternal mortality. Imaging studies like abdominal ultrasonogram, helical computerized tomography and magnetic imaging have been utilized to complement clinical suspicion and decrease ‘negative appendectomies’ but robust data on their routine use is awaited. Although the laparoscopic approach is a useful diagnostic and therapeutic tool in early pregnancy, its use as the primary approach for appendicectomy in pregnancy requires further evaluation as increases in the incidence of fetal loss of 5.6% has been reported compared to 3.1% in open access surgery

Fulltext A Case of Appendiceal Goblet Cell Carcinoid Tumor: Getting it right under the Microscope

Kang WH, Wahab NA, Kamaruddin NA

J ASEAN Fed Endocr Soc, 2020;35(1):102-104.
PMID: 33442175 DOI: 10.15605/jafes.035.01.16

Goblet cell carcinoid (GCC) is a rare neoplasm of the vermiform appendix and can be mistaken as a typical neuroendocrine tumour (TNET). The natural history of this disease is more aggressive compared to TNETs and requires a more aggressive approach. We report a case of a 37-year-old male who was initially diagnosed with TNET, but subsequently revised as Tang's A GCC. He underwent appendectomy and right hemicolectomy. Aside from a persistently elevated carcinoembyrogenic antigen (CEA) result, his 18F-fluorodeoxyglucose (FDG) PET/CT and a 68-Gallium DOTATATE PET/CT scan showed no FDG or DOTATATE avid lesions.

Diverticular disease of the large bowel in Singapore. An autopsy survey

Lee YS

Dis Colon Rectum, 1986 May;29(5):330-5.
PMID: 3084185

One thousand fourteen consecutive large intestines were removed at autopsy from persons over the age of 14 years and examined for diverticular disease. Diverticulosis was encountered in 194 patients (19 percent). The lesion appeared early in life, after the second decade. Men were affected more frequently than women before the age of 60 years. Chinese men had significantly more diverticular disease than Malayan men (P less than 0.01) and Indian men (P less than 0.02). Chinese men also had significantly more diverticular disease than Chinese women. There was a predominance of right colon involvement, with the disease affecting especially the ascending colon and cecum. This pattern was observed in all three major ethnic groups, and in both the Singapore-born and foreign-born Singaporeans. The cause of right-sided diverticulosis is unknown. It appears that, while adoption of the western diet may influence the prevalence of diverticular disease, the site of predilection is determined more by racial or genetic predisposition. All diverticula examined histologically were false, including 39 (20 percent) solitary diverticula. The distribution of solitary diverticula was similar to that of multiple diverticulosis. It is suggested that solitary and multiple diverticulosis are part of the spectrum of the same disease.

PMID: 33742645

Iliac aneurysms are rare in children, especially mycotic aneurysms. Re-vascularization is challenging given the infected field and concern on patency due to their growth potential and a longer life-span. We report a complex case of a mycotic iliac aneurysm in a child. A 12-years-old boy with a previous history of infective endocarditis was referred to us for a right common iliac mycotic aneurysm after presenting with pain. A balloon-expandable stent-graft was deployed across the aneurysm during the acute presentation. He improved post-operatively, but developed abdominal pain four weeks later. A repeat computed tomography (CT) imaging showed a new inflammation of the appendix which was adhered to the calcified wall of the aneurysm and an endoleak from the internal iliac artery. A laparotomy was performed and the right internal iliac artery ligated along with an appendicectomy and omental pedicle. Postoperatively the patient was well and discharged home. Six-month surveillance revealed a healthy child and imaging showed a patent stent-graft and no residual collection.

Fulltext Intraspecific macroscopic digestive anatomy of ring-tailed lemurs (Lemur catta), including a comparison of frozen and formalin-stored specimens

Clauss M, Trümpler J, Ackermans NL, Kitchener AC, Hantke G, Stagegaard J, et al.

Primates, 2021 Mar;62(2):431-441.

Digestive tract measurements are often considered species specific, but little information exists on the degree to which they change during ontogeny within a species. Additionally, access to anatomical material from nondomestic species is often limited, with fixed tissues possibly representing the only available source, though the degree to which this material is representative in terms of dimensions and weight is debatable. In the present study, the macroscopic anatomy of the digestive tract (length of intestinal sections, and tissue weights of stomach and intestines) of 58 Lemur catta [ranging in age from 1 month (neonates) to 25 years], which had been stored frozen (n = 27) or fixed in formalin (n = 31), was quantified. Particular attention was paid to the caecum and the possible presence of an appendix. The intraspecific allometric scaling of body mass (BM)0.46[0.40;0.51] for total intestine length and BM0.48[0.41;0.54] for small intestine length was higher than the expected geometric scaling of BM0.33, and similar to that reported in the literature for interspecific scaling. This difference in scaling is usually explained by the hypothesis that, to maintain optimal absorption, the diameter of the intestinal tube cannot increase geometrically. Therefore, geometric volume gain of increasing body mass is accommodated for by more-than-geometric length scaling. According to the literature, not all L. catta have an appendix. No appendix was found in the specimens in the present study. The proportions of length measurements did not change markedly during ontogeny, indicating that the proportions of the foetus are representative of those of the adult animal. By contrast, width and tissue-mass scaling of the caecum indicated disproportionate growth of this organ during ontogeny that was not reflected in its length. Compared to overall intraspecific variation, the method of storage (frozen vs. formalin) had no relevant impact on length or weight measurements.
