    Comparison of the pull and introducer percutaneous endoscopic gastrostomy techniques in patients with head and neck cancer
    (2017) RETES, Felipe A.; KAWAGUTI, Fabio S.; LIMA, Marcelo S. de; MARTINS, Bruno da Costa; UEMURA, Ricardo S.; PAULO, Gustavo A. de; PENNACCHI, Caterina M. P.; GUSMON, Carla; RIBEIRO, Adriana V. S.; BABA, Elisa R.; GEIGER, Sebastian N.; SORBELLO, Mauricio P.; KULCSAR, Marco A.; RIBEIRO JR., Ulysses; MALUF-FILHO, Fauze
    Background and study aims: Percutaneous endoscopic gastrostomy (PEG) in head and neck cancer (HNC) patients is associated with higher complication and mortality rates when compared to a general patient population. The pull technique is still the preferred technique worldwide but it has some limitations. The aim of this study is to compare the pull and introducer PEG techniques in patients with HNC. Patients and methods: This study is based on a retrospective analysis of a prospectively collected database of 309 patients with HNC who underwent PEG in the Cancer Institute of SAo Paulo. Results: The procedure was performed with the standard endoscope in 205 patients and the introducer technique was used in 137 patients. There was one procedure-related mortality. Age, sex and albumin level were similar in both groups. However in the introducer technique group, patients had a higher tumor stage, a lower Karnofsky status, and presented more frequently with tracheostomy and trismus. Overall, major, minor, immediate and late complications and 30-day mortality rates were similar but the introducer technique group presented more minor bleeding and tube dysfunctions. Conclusion: The push and introducer PEG techniques seem to be both safe and effective but present different complication profiles. The choice of PEG technique in patients with HNC should be made individually.

    Diagnosis of Clinical Complete Response by Probe-Based Confocal Laser Endomicroscopy (pCLE) After Chemoradiation for Advanced Rectal Cancer
    (2021) SAFATLE-RIBEIRO, Adriana Vaz; MARQUES, Carlos Frederico Sparapan; PIRES, Clelma; ARRAES, Livia; BABA, Elisa Ryoka; MEIRELLES, Luciana; KAWAGUTI, Fabio Shigehissa; MARTINS, Bruno da Costa; LENZ, Luciano Tolentino; LIMA, Marcelo Simas de; GUSMON-OLIVEIRA, Carla Cristina; RIBEIRO JR., Ulysses; MALUF-FILHO, Fauze; NAHAS, Sergio Carlos
    Background Neoadjuvant chemoradiotherapy (nCRxt) followed by radical surgery is the optimal treatment for advanced rectal adenocarcinoma. Patients with clinical complete response (cCR) may be followed closely without immediate surgery. Probe-based confocal laser endomicroscopy (pCLE) is a real-time in vivo method that allows acquisition of optical biopsies with 1000 times magnification, evaluating both epithelial and vascular patterns. Aim To evaluate the role of pCLE in the diagnosis of cCR after nCRxt for advanced rectal adenocarcinoma. Methods pCLE was performed in 47 patients with locally advanced rectal adenocarcinoma (T3/T4, or N+) who underwent nCRxt (5-fluorouracil, 5040 cGy). Results Twenty-seven (57.5%) patients were men, and the mean age was 62.8 years. Thirty-seven had partial response confirmed by pCLE. Ten (21.3%) patients had good endoscopic response and presented small ulcer (n = 5) or residual scar (n = 5). After nCRxt, the essential features to differentiate malignancy from post-radiation alterations at pCLE were the presence of irregular crypts, budding, back-to-back glands, cribriform pattern, increased vessel/crypt ratio, and fluorescein leakage. A scoring system was created considering these epithelial and vascular features, with high accuracy for differentiating patients with complete response from those with residual neoplasia (p < 0.00001). pCLE sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were 100%, 71.4%, 95.2%, 100%, and 95.7%, respectively. Conclusions (1) pCLE evaluation of epithelial and vascular features may improve the diagnosis of cCR and may alter patient management; (2) pCLE might be valuable for identifying patients with advanced rectal cancer who will benefit from watch and wait strategy, avoiding immediate surgical treatment.

    A Sessile Serrated Lesion Overlying a Submucosal Colonic Lipoma: An Endoscopic Rarity Identified Using Artificial Intelligence
    (2023) FACANALI, Carolina Bortolozzo Graciolli; FACANALI JUNIOR, Marcio Roberto; SOBRADO JUNIOR, Carlos Walter; SAFATLE-RIBEIRO, Adriana Vaz
    Objective: Rare coexistence of disease or pathologyBackground: Lipomas are benign, slow-growing mesenchymal neoplasms, more prevalent in females, with a peak incidence in the fifth to sixth decades of life. Generally, due to their low clinical relevance, they receive little attention in the literature. Uncommon in the colon, lipomas are most often identified as an incidentaloma in asymptomatic patients during colonoscopy, and overlapping with epithelial lesions is a rare finding. Serrated polyps used to be considered as hyperplastic polyps without any malignant potential; however, currently, the serrated pathway accounts for one-third of all colorectal cancers. Here, we describe a rare case of a sessile serrated lesion on a submucosal lipoma identified with the aid of artificial intelligence.Case Report: A 60-year-old woman underwent screening colonoscopy for colorectal cancer after a positive fecal immunochemical test. A high-definition colonoscopy with the aid of artificial intelligence (Fujifilm CAD EYE) was performed. A flat lesion at the right colon was diagnosed with white-light endoscopy simultaneously identified by artificial intelligence, which classified the lesion as hyperplastic. Resection was performed through mucosectomy, and a sign of naked fat was observed at the base of the resected lesion. Histopathology of the specimen characterized a submucosal lipoma associated with a sessile serrated lesion.Conclusions: We describe a rare case of sessile serrated lesion on a colon lipoma, identified with the aid of artificial intelligence. We carried out a brief literature review and discussed the main findings and aspects related to the literature.
