Kasus obstruksi intestinal dengan peningkatan tekanan intraluminal merupakan kasus yang sering ditemukan
dan memiliki angka morbiditas dan mortalitas yang tinggi. Dekompresi intestinal praoperasi terbukti
memberikan luaran paskaoperasi yang lebih baik.
Tujuan
Penelitian dengan judul “Perbedaan Jumlah
Sebukan Sel Radang dan Ketebalan Usus Halus Pada Peningkatan
Tekanan Intraluminal Usus dengan dan tanpa Dekompresi: Studi Eksperimental Pada Tikus Albino
Galur Wistar (Rattus novergicus)” ini bertujuan untuk mengetahui perbedaan
jumlah sebukan sel radang dan ketebalan usus besar pada tikus albino galur wistar
dengan peningkatan tekanan intraluminal usus dengan dan tanpa dekompresi.
Metode
Penelitian ini menggunakan metode eksperimental post test only dengan melibatkan 30 ekor Tikus Albino Galur Wistar
sebagai subyek penelitian. Penelitian dilakukan di Laboratorium Pusat Antar
Universitas (PAU) dan Laboratorium Patologi Anatomi Universitas Gadjah Mada.
Penelitian dengan subyek tikus galur wistar ini menggunakan teknik acak
sederhana dan analisis data dengan one
way ANOVA menggunakan SPSS versi 25.0.0.0.
Hasil
Penelitian menunjukkan bahwa terdapat Perbedaaan signifikan pada rerata
jumlah neutrofil pada kelompok kontrol terhadap kelompok perlakuan A (p=
0,001). Perbedaan signifikan pada rerata jumlah neutrofil juga ditemukan pada kelompok A terhadap
kelompok perlakuan B (p=0,002). Secara statistik, terdapat perbedaan bermakna
jumlah sebukan sel neutrofil pada mukosa usus halus tikus yang mengalami
peningkatan tekanan intraluminal usus antara yang didekompresi dan yang tidak didekompresi.
Penelitian juga menunjukkan perbedaan signifikan pada jumlah rerata
sel plasma pada kelompok
kontrol terhadap kelompok
perlakuan A (p=0,006). Perbedaan signifikan
pada rerata jumlah sel plasma
juga ditemukan pada kelompok kontrol
terhadap kelompok perlakuan B
(p=0,004). Sebaliknya, tidak terdapat perbedaan bermakna pada jumlah rerata sel plasma antar perlakuan (p=0,909).
Secara statistik, tidak
terdapat perbedaan
bermakna jumlah
sebukan sel plasma pada mukosa usus besar tikus yang mengalami peningkatan
tekanan intraluminal usus, baik yang didekompresi maupun yang tidak didekompresi.
Pada penelitian ini tidak terdapat perbedaan rerata jumlah sel limfosit
yang signifikan secara statistik pada kelompok subyek penelitian (p >0,776).Tidak terdapat perbedaan rerata ketebalan usus
halus yang signifikan secara statistik pada kelompok subyek penelitian (p >0,127).
Kesimpulan
Pada penelitian ini, terdapat perbedaan bermakna jumlah sebukan sel neutrofil pada mukosa usus halus tikus yang mengalami peningkatan tekanan intraluminal usus antara yang didekompresi dan yang tidak didekompresi

ABSTRACT
Background: Intestinal obstruction with increased intraluminal pressure is a
commonly encountered condition with high morbidity and mortality rates.
Preoperative intestinal decompression has been shown to improve postoperative
outcomes.
Objective: This study, titled "Differences in the Number of Inflammatory
Cell Infiltrates and Thickness of the Small Intestine in Increased Intraluminal
Pressure with and without Decompression: An Experimental Study on Wistar
Albino Rats (Rattus
norvegicus)," aims to investigate the differences in the
number of inflammatory cell infiltrates and the thickness of the small
intestine in Wistar albino rats with increased intraluminal pressure, with and
without decompression.
Method: This experimental
post-test-only study involved 30 Wistar albino rats as subjects. The research
was conducted at the Center for Inter-University Laboratory (PAU) and the
Department of Anatomical Pathology, Universitas Gadjah Mada. The study utilized
a simple randomization technique and data analysis was performed using one-way
ANOVA with SPSS version 25.0.0.0..
Results: The study revealed
a significant difference in the mean number of neutrophils between
the control group and Group A
(p = 0.001), as well as between Group A and Group B (p = 0.002). This indicates
a notable variation in neutrophil infiltrates in the mucosa of the small
intestine in rats with increased intraluminal pressure depending on whether
decompression was performed. Conversely, although there was a significant
difference in the mean number of plasma cells between the control group and
Group A (p = 0.006) and between
the control group and Group B (p = 0.004),
no significant difference was observed between
the treatment groups (p = 0.909). This suggests that plasma cell infiltrates in
the mucosa of the large intestine did not significantly differ between
decompressed and non-decompressed conditions. Furthermore, there were no
statistically significant differences in the mean number of lymphocytes (p >
0.776) or in the mean thickness of the small intestine (p > 0.127) among the
study groups. Thus, the lack of significant differences in lymphocyte counts
and intestinal thickness suggests that these
factors may not be influenced by decompression in the
context of increased intraluminal pressure.
Conclusion: This study found
a significant difference in the number
of neutrophil infiltrates in the mucosa of the small intestine in rats
with increased intraluminal pressure between those that underwent decompression
and those that did not.
