    Endoscopic Ultrasound-Guided Tissue Acquisition Versus Fine Needle Aspiration for Diagnosis of Pancreatic Ductal Adenocarcinoma
    (2023) OMAIRI, Tarik W.; MICELLI-NETO, Otavio; TAGLIERI, Eloy; ARAUJO-FILHO, Jesse C. de; FARIA, Andressa Tome R. de; GOLDMAN, Suzan M.; SURJAN, Rodrigo Canada T.; MACHADO, Marcel A.; VENCO, Filadelfio E.; ARDENGH, Jose C.
    Objectives: Compare the 22G needle versus EchoTip ProCore & REG; 20 (Cook Medical, Bloomington, IN, USA) on their handling, specimen suitability, amount of tissue obtained, diagnostic performance, the possibility of immunohistochemistry, and rate of adverse events. Materials and methods: This is a retrospective, comparative study of consecutively examined patients with pancreatic masses who underwent endosonography-guided fine needle aspiration (FNA) via the 22G needle, and endosonography-guided tissue acquisition (TA) via ProCore 20 (PC20). The operator evaluated needle insertion and subjectively classified the specimen. The pathologist measured the samples, classified the amount of tissue, and determined the influence of bleeding on the interpretation. Results: A total of 129 patients participated in the study, out of whom 52 underwent endosonographyguided FNA with 22G and 77 underwent endosonography-guided TA with a PC20 needle. Malignant lesions were found in 106, and 23 had benign lesions. The duodenal route was used in 62% of patients. The 22G needle was easier to introduce (p=0.0495). However, PC20 obtained a larger amount (p<0.01) with fewer punctures (p<0.001). The PC20 also yielded a larger average microcore diameter (p=0.0032). Microhistology was adequate for 22G and PC20 in 22 (42.2%) and 50 (78.1%) specimens, respectively (p<0.001). Bleeding was not significantly different (p>0.999). Immunohistochemistry was possible in 36 (69.2%) and 40 (51.9%) specimens obtained by 22G and PC20, respectively (p=0.075). The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of 22G were 93.5%, 100%, 100%, 66.7%, and 94.2%, respectively; and for PC20, it was 95%, 100%, 100%, 85%, and 96.1%, respectively. Mild bleeding was the most common early adverse event, occurring in 2/52 (3.8%) 22G and 4/77 (5.2%) PC20 cases (p>0.05). Conclusions: The PC20 required fewer punctures and reduced the need for immunohistochemistry as it yielded better and larger microcores. Its ease of insertion into the target lesion makes it a good option to obtain satisfactory microcore specimens in difficult positions, such as the transduodenal route.

    First Robotic Roux-en-Y Gastric Bypass for the Treatment of Refractory Gastroesophageal Reflux Disease in a Patient With Systemic Sclerosis
    (2023) SURJAN, Rodrigo Canada T.; SILVEIRA, Sergio; FIGUEIRA, Estela R.
    Systemic sclerosis (SSc) is an immune-mediated disease that results in fibrosis of the skin and internal organs. Refractory gastroesophageal reflux disease (GERD) associated with severe esophageal dysmotility is common in SSc patients, and surgical treatment with usual anti-reflux procedures such as fundoplications is associated with dismal symptomatic relief and postoperative dysphagia. We report the first robotic short -limb Roux-en-Y gastric bypass (RYGB) with a short Roux limb for the treatment of GERD in a patient with SSc with intense esophageal dysmotility. The operative time was two hours. The procedure and postoperative course were uneventful. The patient presented complete relief of gastroesophageal reflux symptoms and no postoperative dysphagia in a two-year follow-up. Therefore, short-limb RYGB is a safe and very effective alternative for the treatment of severe GERD in patients with SSc. The robotic surgical platform may have some advantages compared to conventional laparoscopy.
