“…Loss of stratification indicates destruction of the normal structure of the gastric wall. The presence of gastric cancer should be considered when a wall thickness of >10 mm is observed (22). In the present study, wall thickness ranged between 7 and 20 mm (mean, 12.2±5.9 mm).…”

Abstract. Gastric cancer is occasionally diagnosed using transabdominal ultrasonography (US) during screening or investigation of patients with abdominal symptoms. Therefore, the present study analyzed the association of the tumor diameter, pathological T (pT) staging and depth of invasion with the detection of gastric cancer using US. Patient records were analyzed retrospectively and 13 patients were enrolled, who underwent US screening prior to endoscopic mucosal resection, endoscopic submucosal dissection or surgery. In total, 5 patients were diagnosed with gastric cancer using US (positive detection group), while US was unable to detect the gastric cancer in 8 patients (negative detection group). The tumor diameter and depth of invasion were determined by pathologists. One-way analysis of variance or the χ 2 test was performed. Wall thickness in gastric cancer cases ranged between 7 and 20 mm (mean, 12.2±5.9 mm), as measured using abdominal US. The hemoglobin level was significantly lower in the positive detection patients compared with the negative detection patients (P=0.0455). In addition, the diameters of the gastric wall in the negative and positive detection patients were 24.5±16.4 and 54.4±26.2 mm, respectively (P=0.0266). These results indicate that gastric cancer in the positive detection patients were at a more advanced-stage compared with that in the negative detection patients. Furthermore, gastric cancer with a stage over pT2 was diagnosed using abdominal US (P=0.0242), whereas stage pT1a gastric cancer was not detected by abdominal US. Gastric tumors invading deeper than the submucosa were diagnosed using US (P=0.0242). However, the gastric cancer cases limited to the mucosa remained undetected. In conclusion, the detection of gastric cancer correlated well with the tumor diameter, pT staging and depth of invasion.

“…In patients with mass or wall thickening detected on ultrasonography, additional workup such as barium study, CT or endoscopy would be occasionally necessary for making a specific diagnosis, following clinical symptoms and laboratory findings, and endoscopic intervention methods and biopsy are applied as the gold standard [2]. It is recently observed that there is not a remarkable advancement in GI tract evaluations despite all developments in radiological imaging methods, and the high costs of examination, risk of radiation and difficult applicability in patients in modern CT methods emphasize the importance of US evaluations and stand US out as the scanning method in malignities of the GI tract [3]. The aim of our study is to emphasize the role of ultrasonography, which has a substantial sensitivity in diagnosis of gastrointestinal cancers, as well as the ultrasonographic findings with superiority in identifying malignity and to investigate the role of this method, which is commonly used before endoscopic interventions as it is non-invasive and easily-accessible.…”

ÖzetAmaç: Günümüzde radyolojik görüntüleme yöntemlerindeki tüm gelişmelere rağmen gastrointestinal kanalın (GIK) incelemelerinde belirgin ilerleme sağ-lanamadığı gözlenmekte, geliştirilen modern BT yöntemlerinde de tetkikin pahalılığı, radyasyon riski ve hasta açısından uygulanabilirliğinin kolay olmaması, ultrasonografik (US) incelemelerin önemini arttırmakta ve US'yi GİK malignitelerinde tarama yöntemi olarak ön plana çıkarmaktadır. Bu çalış-mada her ne kadar tanıda gold standartın üst gastrointestinal sistem endoskopisi veya kolonoskopi olduğu bilinsede ultrasonografinin gastrointestinal kanal kanserlerinde rolü araştırılmıştır. Gereç ve Yöntem: Bu çalışma-ya anamnez ve fizik muayene bulgularıyla gastrointestinal kanal malignitesi ön tanısıyla ultrasonografi ve endoskopik tetkiklerin planlanan 40 hasta alın-mıştır. Tüm hastalara ultrasonografi ve endoskopi uygulandı ve histopatolojik tanılarla sonuçlar karşılaştırılmıştır. Bulgular: Çalışmaya 25'i (%62,5) erkek, 15'i (%37,5) kadın toplam 40 hasta alınmıştır. Hastaların yaşı 63,1±11,5 olarak tespit edildi. Hastalardan 15'inde ( %37,5) histopatolojik olarak malignite tespit edildi. Ultrasonun GI kanal kanserleri saptamada sensitivitesi %71,4, spesivitesi %75,7 pozitif prediktif değeri %65,2, negatif prediktif değeri %19,3 olarak saptandı. Endoskopik girişimlerin sensitivitesi %100, spesifitesi %96, pozitif prediktif değeri %93,7 olarak saptandı. Tartışma: Abdominal ultrasonografi gastrik-kolonik kanserlerin saptanmasında oldukça spesifik ve sensitif bir yöntemdir. Bu nedenle noninvaziv, kolay ulaşılabilir, radyasyon içermeyen, ucuz, risksiz olan bu yöntemin diğer tanı koydurucu yön-temlerden önce uygulanmasının faydalı olduğuna inanmaktayız . Anahtar KelimelerGastrointestinal Kanal; Kanser; Ultrasonografi; Endoskopi Abstract Aim: It is recently observed that there is not a remarkable advancement in gastrointestinal (GI) tract evaluations despite all developments in radiological imaging methods, and the high costs of examination, risk of radiation and difficult applicability in patients in modern CT methods emphasize the importance of ultrasonography (US) evaluations and stand US out as the scanning method in malignities of the GI tract. This study investigates the role of ultrasonography in cancers of the gastrointestinal tract, although the gold standard is known to be the endoscopy of the upper gastrointestinal tract or colonoscopy. Material and Method: The study included 40 patients whose ultrasonography and endoscopic examinations were planned with the preliminary diagnosis of tract malignity with findings of anamnesis and physical examination. All patients underwent ultrasonography and endoscopy, and results were compared with histopathologic diagnosis. Results: The study included a total of 40 patients, including 25 (62,5%) male and 15 (37,5%) female patients. Malignity was histopathologically identified in 15 (37,5%) patients. The sensitivity of ultrasound to identify cancers to the GI tract was 71,4%, its specificity was 75,7%, positive predictive value...

“…POCUS has proved to be an accurate technique for the diagnosis of gastrointestinal cancers [7,8]. The diagnosis of colon carcinoma on ultrasonography is made based on the sonographic finding of a localised irregular colon wall thickening or a hypoechoic mass with a hyperechoic centre (Pseudokidney sign [1]).…”

We present a case of a 64-year-old gentleman for whom point of care ultrasound (POCUS) expedited the diagnosis and subsequent early treatment of colon adenocarcinoma. He was referred by his primary provider to our clinic for abdominal bloating. He had no other abdominal symptoms such as abdominal pain, change in bowel habits or rectal bleeding. He had no constitutional symptoms such as weight loss. The patient’s abdominal examination was also unremarkable. However, POCUS identified a 6 cm long hypoechoic circumscribed colon wall thickening around the hyperechoic pattern of bowel lumen (Pseudokidney sign) in the right upper quadrant, which suggested the presence of an ascending colon carcinoma. In view of this prompt bedside diagnosis, we organised a colonoscopy, staging computerised tomographic scan and colorectal surgery consultation the next day. After the locally advanced colorectal carcinoma was confirmed, the patient had curative surgery within 3 weeks of his presentation to the clinic.
