Background: Acute appendicitis (AA) is the most common surgical emergency in patients who visit the emergency department with abdominal pain. In some of the patients who were operated with a prediagnosis of AA, lymphoid hyperplasia, fecalitis, enterobius vermicularis, carcinoid tumor, or adenoma are determined without transmural inflammation in microscopic examination of the appendix. 'Submucosal lipomatosis' is also another entity that has been rarely reported in appendix localization. In this study, we aimed to determine the frequency and severity of submucosal fatty tissue (SFT) in appendectomy specimens and identify risk factors.
Materials and Methods: 293 appendectomy specimens were evaluated retrospectively. The amounts of SFT (A0: None, A1: Isolated adipocytes (Mild), A2: Small adipocyte groups (Moderate), A3: Prominent adipocyte groups (Marked), A4: Severe adipocyte groups that narrow the lumen (Severe)) and the groups that were created according to the amounts of SFT (Group 1: Cases with A1,2,3,4, group 2: Cases with A2,3,4, group 3: Cases with A3,4) were determined in hematoxylin-eosin sections.
Results:
91.47% of the cases had any amount of SFT. Amounts of SFT were mild in 23.89%, moderate in 46.76%, marked in 18.09%, and severe in 2.73%. All of the cases without SFT were in pediatric age. When the amount of SFT increased, the mean age and adult rate increased regularly (p<0.05). As 68% of the cases without SFT were female, male predominance was observed in cases with SFT. When the amount of SFT increased, male rate increased regularly (p<0.05). AA wasn’t determined in 26,28% of the cases. The AA rate in the group without SFT (20%) was marked lower than group 1 (78,73%), group 2 (82,32%), and group 3 (83,87%) (p<0.05). The most prominent increase in AA rate was between the group without SFT and group 1 which was the most sensitive group to the amount of SFT. When group 1,2,3 were compared, no significant increase in the AA ratio was found.
Conclusions: The presence of SFT in the appendix is a common condition. Age increase and male gender are risk factors for the accumulation of SFT. Due to SFT accumulation increases the risk of AA, it would be logical to classify it as mild/moderate/marked/severe, and accept it as 'Submucosal lipomatosis'.

Amaç: Akut apandisit (AA) karın ağrısı ile acil servise başvuran hastalarda en sık saptanan cerrahi acildir. AA ön tanısı ile opere edilen hastaların bir kısmında apendiksin mikroskobik incelemesinde transmural inflamasyon eşlik etmeksizin lenfoid hiperplazi, fekalit, enterobius vermikularis, karsionid tümör veya adenom saptanır. ‘Submukozal lipomatozis’te apendikste nadiren bildirilen bir diğer antitedir. Bu çalışmada apendektomi spesmenlerinde submukozal yağlı doku (SYD) varlığının sıklığını ve şiddetini belirlemeyi, risk faktörlerini tanımlamayı amaçladık.
Materyal ve Metod: 293 apendektomi spesmeni retrospektif olarak incelenmiştir. Hematoksilen-eozin kesitlerde SYD miktarları (M0: Yok, M1: İzole adipositler (Hafif), M2: Küçük adiposit grupları (Orta), M3: Belirgin adiposit grupları (Belirgin), M4: Lümeni daraltan adiposit grupları (Şiddetli)) ve SYD miktarlarına göre oluşturulan gruplar (Grup 1: M1,2,3,4 olan olgular, grup 2: M2,3,4 olan olgular, grup 3: M3,4 olan olgular) belirlenmiştir.
Bulgular: Olguların %91,47’sinde değişik miktarlarda SYD mevcuttur. SYD miktarları olguların %23,89’unda hafif, %46,76’sında orta, %18,09’unda belirgin, %2,73’ünde şiddetlidir. SYD içermeyen olguların tamamı pediatrik yaş grubundadır. SYD miktarı arttıkça yaş ortalamaları ve yetişkin oranları düzenli olarak artmıştır (p<0,05). SYD içermeyen olguların %68’i kadınken, SYD içeren olgularda erkek hakimiyeti görülmüştür. SYD miktarı arttıkça erkek oranları düzenli olarak artmıştır (p<0,05). Olguların %26,28’inde AA saptanmamıştır. AA oranları SYD içermeyen grupta (%20), grup 1 (%78,73), grup 2 (%82,32) ve grup 3‘e (%83,87) göre belirgin düşüktür (p<0.05). AA oranında en belirgin artış SYD içermeyen grup ile SYD miktarına en hassas olan grup 1 arasındadır. Grup 1,2,3 karşılaştırıldığında AA oranlarında anlamlı artış belirlenememiştir.
Sonuç: Apendikste SYD varlığı sık görülen bir durumdur. Yaş artışı ve erkek cinsiyet SYD birikimi için risk faktörüdür. SYD birikiminin AA riskini arttırması sebebiyle hafif/orta/belirgin/şiddetli olarak sınıflandırılarak ‘Submukozal lipomatozis’ kabul edilmesi mantıklı olacaktır.
