"Pendahuluan: COVID-19 telah dilaporkan menyebabkan berbagai gejala, termasuk gejala pernapasan dan gejala gastrointestinal seperti mual, muntah, dan diare. Standar emas untuk pengujian COVID-19 adalah RT-PCR menggunakan koleksi swab nasofaring. Namun, beberapa penelitian menunjukkan bahwa pengambilan swab nasofaring memiliki beberapa keterbatasan, terutama untuk mendeteksi gejala gastrointestinal. Salah satu variabel dalam pengujian RT-PCR adalah Nilai CT yang diketahui dapat meningkatkan spesifisitas pengujian. Namun, belum ada penelitian yang menghubungkan Nilai CT pasien dengan pengambilan sampel swab anal dengan gejala gastrointestinal terkait COVID-19. Metode: Penelitian ini menggunakan desain penelitian analitik, khususnya penelitian potong lintang. Data sekunder diperoleh dan diolah yang berisi data pribadi, pekerjaan, dan hasil CT Value. Analisis lebih lanjut dilakukan pada hubungan antara gejala gastrointestinal dan tingkat Nilai CT pada swab anal. Hasil: Distribusi tingkat Nilai CT responden berdasarkan cut off >25 untuk tinggi, dan <25 untuk rendah dan sedang. Dari 37 subjek, 1 orang (2,7%) memiliki Nilai CT rendah dan 36 pasien memiliki Nilai CT tinggi. Distribusi gejala subjek didapatkan 15 pasien (40,5%) tidak mengalami gejala gastrointestinal dan sebanyak 22 pasien (59,5%) mengalami gejala gastrointestinal. Gejala gastrointestinal umum yang dilaporkan pada pasien meliputi: mual (54,1%), muntah (18,9%), sakit perut (16,2%) dan diare (13,5%). Namun, tidak ada hubungan yang signifikan (p>0,05) antara Nilai CT pada pengambilan anal swab dengan gejala gastrointestinal pada pasien COVID-19. Kesimpulan: Hubungan antara Nilai CT pada pengambilan anal swab dengan gejala gastrointestinal pada pasien COVID-19 tidak menunjukkan hubungan yang signifikan. Penelitian lebih lanjut tentang faktor risiko yang mempengaruhi hasil nilai CT direkomendasikan.

Introduction: COVID-19 has been reported to cause a range of symptoms, including respiratory symptoms and gastrointestinal symptoms such as nausea, vomiting, and diarrhea. The gold standard for COVID-19 testing is RT-PCR using nasopharyngeal swab collection. However, several studies have shown that taking nasopharyngeal swabs have some limitation, particularly to detect gastrointestinal symptoms. One of the variables in RT-PCR testing is CT Value, which known can increase specifity of the test. However, there has been no study linking the CT Value of patients with anal swab sampling with COVID-19 related gastrointestinal symptoms. Methods: This study used an analytical research design, particularly a cross-sectional study. Secondary data were obtained and processed which contained personal data, work, and CT Value results. Further analysis was conducted on the relationship between gastrointestinal symptoms and the level of CT Value on anal swabs. Result: The distribution of respondents' CT Value levels were based on a cut off of >25 for high, and <25 for low and moderate. From 37 subjects, 1 person (2.7%) had a low CT Value and 36 patients had a high CT Value. The distribution of the subject's symptoms found 15 patients (40.5%) had no gastrointestinal symptoms and as many as 22 patients (59.5%) had gastrointestinal symptoms. Common gastrointestinal symptoms reported in patients include: nausea (54.1%), vomiting (18.9%), abdominal pain (16.2%) and diarrhea (13.5%). However, there was no significant relationship (p>0.05) between CT Value in anal swab taking and gastrointestinal symptoms in COVID-19 patients. Conclusion: The association between CT Value in anal swab taking and gastrointestinal symptoms in COVID-19 patients did not show a significant relationship. Further research on risk factors affecting the CT value results are recommended"

Background: Increased gastric residual volume is a sign of food intolerance. Food intolerance is one form of gastrointestinal disorder. Gastrointestinal disorder often occurs in critically ill patients. MSOFA is one of the scoring system to assess disease severity in critically ill patients. Gastrointestinal system hasn't included in any scoring system. This study was to determine the correlation of gastric residual volume with disease severity based on MSOFA, and whether the gastric residual volume may be complementary parameters MSOFA scoring system.

Methods: This study used a prospective cohort design. Data collection was conducted in February-April 2014 in the ICU RSCM. Total gastric residual volume was measured in the first and second 24 hours of treatment. MSOFA score measured on day I and II.. Data were collected using a research form. Data obtained test statistical analysis.

Results: Total of 72 subjects enrolled in this study. Gastric residual volume difference was significant in the first and second 24 hours. There is a correlation between second 24-hour gastric residual volume with second day of MSOFA score (p <0.001; r 0,544). The addition of gastric residual volume score on the MSOFA scoring system did not add sensitivity and specificity of the prediction of critically ill patient mortality.

Conclusions: There is a correlation between gastric residual volume with disease severity scores that were calculated with MSOFA for patients admitted to the ICU RSCM. The addition of gastric residual volume score on the MSOFA scoring system did not add sensitivity and specificity of the prediction of critically ill patient mortality."

"Approximately 60% of patients who die due to melanoma have gastrointestinal metastases at autopsy, yet ante mortem diagnosis is uncommon. The small bowel is the most frequent intestinal site of metastasis and prognosis is very poor with a median survival after operation was 6.2 months (range: 1-42 months). Bowel metastases may appear radiologically as polypoid mucosal lesions, submucosal nodules, diffuse infiltration with thickening of the intestinal wall, or serosal implants. Bowel obstruction due into intussusceptions is common clinical presentation of gastrointestinal metastasis; other presentation include gastrointestinal bleeding, perforation and large masses.We reported a case of m eta static melanoma to small bowel, whose had hematemesis melena, abdominal pain, diarrhea and weight loss without primary cutaneus melanoma. Gastroduodenoscopy appeared normal. The ultrasonography of bowel showed a"doughnut" configuration with concentric rings of bowel wall. Left lateral decubitus abdominal radiographies showed free air appearances. Laparatorny reported three location of invaginalion (intussuception) with multiple polyposis at ileo-jejttnal segment (29 pieces of polyp) and jejunum perforation. Resection and end-to end anastomosis of the. affected segment had been performed with no serious complication after this. Miscroscopical examination of specimen showed metasiatic melanoma malignant in 3 lymph nodes. Eight weeks later patients died with distant metastases to brain."

Background

The first US case of Covid 19 experiencing gastrointestinal disorders. Study in China found that patients with respiratory and gastrointestinal symptoms was 47% and there were 3% of patients with gastrointestinal symptoms only without respiratory symptoms.

It was found that positive results of RT-PCR were not only in the respiratory tract but also in other specimens including feces (29-53.42%). Endoscopic biopsy of several cases also found the SARS CoV-2 virus in the stomach, duodenum, ileum, and rectum. While the study using anal swab obtained 52.6% positive results. There was a case report that PCR examination of the nasopharyngeal swab was negative, but the anal swab was positive and persistent for 42 days. This finding certainly needs further investigation, because there may be cases of Covid-19 that were not detected by the naso-oropharygeal swab RT-PCR swab but can be detected by anal swabs. The RT-PCR method with anal swab is expected to be an alternative to the naso-oropharygeal swab.

Objective

This study test the performance of the anal PCR swab test when compared to the naso-oropharyngeal swab PCR test as a diagnostic tool for Covid-19.

Method

Subjects of this study are patients with suspected or probable Covid-19, aged> 18 years. Subjects with extensive diarrhea, massive hematoschezia or melena, and anal wounds, were not included in the study. RT-PCR anal swab examination was performed with MiRXES Fortitude Kit 2.1

Result

136 eligible subjects were analyzed. There were no complication and complaints from patients during sampling. The sensitivity of RT-PCR anal swab was 36.67% (CI: 28.04 to 45.28%) and specificity 93.75% (CI: 81.88 to 100%). The positive predictive value was 97.78% (CI: 93.47 to 100%) and the negative predictive value was 16.48% (8.86 to 24.10%).

Conclusion

RT-PCR Anal swabs can be a good confirmation tool of COVID 19 cases with a specificity of 93.8%, in suspected and probable COVID 19 cases. Anal swabs are also a safe procedure."
