“…Ultrasonography method can be used to diagnose stomach tumor, intestinal tumor, liver disease, kidney disease, cholestasis, IBD, and hypertrophic gastropathy (Penninck and d'Anjou, 2008). Endoscopy method can be used to diagnose cases such as esophaginitis, stomach ulcer, and achronic gastritis (Banerjee and Reddy, 2012).…”

The aim of this study was to describe the role of diagnostic imaging and endoscopy to define the diagnose of the upper gastrointestinal tract disorder of the Schnauzer. The information from the owner stated that the dog has been vomiting for a year, sometimes containing blood. There might also be a possibility that it had eaten a corpus alienum. This case study covered physical examination, hematology and blood chemical analysis, diagnostic imaging radiography and ultrasonography as well as endoscopy performed. Physical examination showed weight loss and anorexia. Hematology and blood chemical analysis showed an increase in hemoglobin, hematocrit, lymphocyte, ureum, creatinine, alanine aminotransferase (ALT), and alkaline phosphatase (ALP) values. Abdominal radiograph showed no abnormality in the abdominal organs. Abdominal ultrasonography showed a hiperechoic elongated mass attached on the stomach mucosal surface which forms an acoustic shadowing at the ventral. Endoscopy showed pathological lesions that is inconsistency of stomach mucosa surface, foamy fluid in the stomach, ulcers and erosion of the stomach mucosal surface. Based on the diagnostic imaging and endoscopy performed, the animal was clearly diagnosed with chronic gastritis accompanied by stomach ulcer and erosion. ____________________________________________________________________________________________________________________ Key words: diagnostic imaging, endoscopy, Schnauzer, upper gastrointestinal tract disorder ABSTRAK Studi kasus ini bertujuan menetapkan diagnosis gangguan saluran pencernaan atas pada anjing Schnauzer melalui pencitraan and endoskopi. Berdasarkan keterangan dari pemilik (anamnesa), anjing mengalami muntah yang intermiten and sesekali disertai darah yang sudah berlangsung selama satu tahun serta diduga anjing tersebut memakan benda asing. Studi kasus yang dilakukan meliputi pemeriksaan fisik, pemeriksaan hematologi and kimia darah, pencitraan radiografi, pencitraan ultrasonografi, serta endoskopi. Hasil pemeriksaan fisik menunjukkan aandya kondisi kekurusan and anoreksia. Pemeriksaan hematologi and kimia darah menunjukkan aandya peningkatan jumlah limfosit, hemoglobin (Hb), hematokrit (Hct), ureum, kreatinin, alanine aminotransferase (ALT), and alkaline phosphatase (ALP). Pencitraan radiografi abdomen menunjukkan tidak terdapat kelainan pada organ-organ di daerah abdomen. Ultrasonografi lambung terlihat bentukan hiperekhoik memanjang pada permukaan mukosa lambung yang membentuk acoustic shadowing di bagian ventral namun temuan ini tidak spesifik terhadap satu kelainan tertentu. Hasil endoskopi menunjukkan beberapa lesio patologis yang sangat siginifkan yaitu ketidakteraturan mukosa lambung, busa cairan empedu di lambung, ulkus, and erosi lambung. Berdasarkan gabungan hasil diagnosis pencitraan and endoskopi, hewan didiagnosis menderita gastritis kronis disertai ulkus and erosi lambung. ____________________________________________________________________________________________________________________ Kata kunci: diagnosis pen...

“…Flexible endoscopy has revolutionized the diagnosis and treatment of many gastrointestinal diseases. 1 Newly developed endoscopic approaches are applied to domains like gastroesophageal reflux disease (GERD), morbid obesity, pancreatic necrosis, and cholecystitis, which were once possible only through surgery. 2 However, despite numerous advances in endoscopic surgery, some gastroesophageal pathologies remain too difficult or dangerous for the endoluminal approach alone.…”

Flexible endoscopy has evolved to the point that it includes many endoluminal procedures that once required open or laparoscopic surgery, for instance, antireflux surgery, pyloromyotomy, mucosal and submucosal tumor resections, and even full-thickness resection. However, these procedures remain technically demanding due to flexible technology issues: difficult imaging, limited energy devices, lack of staplers, unsatisfactory suturing abilities, and so on. Transgastric laparoscopy or hybrid laparoscopy/flex endoscopy has been described for almost two decades as an alternative to a pure endoluminal approach, mainly for pancreatic pseudocyst drainage and full-thickness and mucosal resection of various lesions. The approach has never been widely adopted mostly due to cumbersome and difficult to maintain methods of gastric access. We propose to expand the indications of transgastric laparoscopy by using novel endoscopically placed ports to replicate endoscopic procedures particularly in the difficult to access proximal stomach such as endoluminal antireflux surgery. Under general anesthesia, five female pigs (mean weight: 27.6 kg) had endoscopic placement of 3, 5 mm intragastric ports (Endo-TAGSS, Leakwood KS, USA) using a technique similar to percutaneous endoscopic gastrostomy. A 5-mm laparoscope was used for visualization. Laparoendoscopic-assisted plication of the gastroesophageal junction (GEJ) was performed using 3-0 interrupted sutures (Polysorb R , Covidien, Mansfield, MA, USA). A functional lumen imagine probe (EndoFLIP R , Crospon, Inc., Galway, Ireland) was used to measure diameter, cross sectional area (CSA), distensibility, and compliance of GEJ before and after intervention. Once the TAGSS ports were removed, the gastrotomies were closed by using endoscopic over-the-scope clips. At the end of the procedure, animals were euthanized. Five laparoendoscopic-assisted endoluminal plications were performed. The mean operative time was 65.6 min (Endoscopic evaluation: 3.2 min, TAGSS Insertion: 11 min, EndoFLIP evaluation + GEJ Plication: 43.25 min, gastric wall closure: 15 minutes). In all cases, this technique was effective and allowed to achieve an adequate GEJ plication by endoscopic grading and EndoFLIP measurements. Median pre-plication GEJ diameter (D) and median pre-plication GEJ cross-sectional area (CSA) were 11.42 mm (8.6-13.6 mm) and 104.8 mm 2 (58-146 mm 2 ). After the procedure, these values were decreased to 6.14 mm (5.7-6.6 mm) and 29.8 mm 2 (25-34 mm 2 ) respectively (p = 0.0079). Median pre-plication distensibility (d) and compliance (C) were 7.87 mm 2 /mmHg (2.4-22.69 mm 2 /mmHg) and 190.56 mm 3 /mmHg (70.9-502.8 mm 3 /mmHg). After the procedure, these values decreased to 1.5 mm 2 /mmHg (0.7-2.2 mm 2 /mmHg) and 52.17 mm 3 /mmHg (21.9-98.7 mm 3 /mmHg) respectively (p = 0.0317). No intraoperative events were observed. Endoscopically, all valves were felt to be transitioned from a Hill grade 3 (normal state for the animal model) to a Hill grade 1 at the procedure completion. A hybrid laparoendosco...
