    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.

    Argon plasma coagulation for the endoscopic treatment of gastrointestinal tumor bleeding: A retrospective comparison with a non-treated historical cohort
    (2016) MARTINS, Bruno Costa; WODAK, Stephanie; GUSMON, Carla C.; SAFATLE-RIBEIRO, Adriana Vaz; KAWAGUTI, Fabio Shiguehissa; BABA, Elisa Ryoka; PENNACCHI, Caterina M. P.; LIMA, Marcelo Simas; RIBEIRO JR., Ulysses; MALUF-FILHO, Fauze
    Background: The endoscopic use of argon plasma coagulation (APC) to achieve hemostasis for upper gastrointestinal tumor bleeding (UGITB) has not been adequately evaluated in controlled trials. This study aimed to evaluate the efficacy of APC for the treatment of upper gastrointestinal bleeding from malignant lesions. Methods: Between January and September 2011, all patients with UGITB underwent high-potency APC therapy (up to 70 Watts). This group was compared with a historical cohort of patients admitted between January and December 2010, when the endoscopic treatment of bleeding malignancies was not routinely performed. Patients were stratified into two categories, grouping the Eastern Cooperative Oncology Group (ECOG) performance status scale: Category I (ECOG 0-2) patients with a good clinical status and Category II (ECOG 3-4) patients with a poor clinical status. Results: Our study had 25 patients with UGITB whom underwent APC treatment and 28 patients whom received no endoscopic therapy. The clinical characteristics of the groups were similar, except for endoscopic active bleeding, which was more frequently detected in APC group. We had 15 patients in the APC group whom had active bleeding, and initial hemostasis was obtained in 11 of them (73.3%). In the control group, four patients had active bleeding. There were no differences in 30-day re-bleeding (33.3% in the APC group versus 14.3% in the control group; p=0.104) and 30-day mortality rates (20.8% in the APC group, versus 42.9% in the control group; p=0.091). When patients were categorized according to their ECOG status, we found that APC therapy had no impact in re-bleeding and mortality rates (Group I: APC versus no endoscopic treatment: re-bleeding p=0.412, mortality p=0.669; Group II: APC versus no endoscopic treatment: re-bleeding p=0.505, mortality p=0.580). Hematemesis and site of bleeding located at the esophagus or duodenum were associated with a higher 30-day mortality. Conclusions: Endoscopic hemostasis of UGITB with APC has no significant impact on 30-day re-bleeding and mortality rates, irrespective of patient performance status.

    Impact of radiotherapy on adverse events of self-expanding metallic stents in patients with esophageal cancer
    (2023) MACHADO, Andressa A.; MARTINS, Bruno C.; JOSINO, Iatagan R.; CHEN, Andre T. C.; HONG, Carlos B. C.; SANTOS, Alisson L. D. R.; LIMA, Gustavo R. A.; CORDERO, Martin A. C.; V, Adriana Safatle-Ribeiro; PENNACCHI, Caterina; GUSMON, Carla C.; PAULO, Gustavo A.; LENZ, Luciano; LIMA, Marcelo S.; BABA, Elisa R.; KAWAGUTI, Fabio S.; UEMURA, Ricardo S.; SALLUM, Rubens A. A.; JR, Ulysses Ribeiro; MALUF-FILHO, Fauze
    Self-expanding metallic stents (SEMS) are considered the treatment of choice for the palliation of dysphagia and fistulas in inoperable esophageal neoplasms. However, the safety of SEMSs in patients who received or who will be submitted to radiotherapy (RT) is uncertain. The study aimed to evaluate the impact of RT on adverse events (AEs) in patients with esophageal cancer with SEMSs. This is a retrospective study conducted at a tertiary cancer hospital from 2009 to 2018. We collected information regarding RT, the histological type of the tumor, the model of SEMSs and AEs after stent placement. Three hundred twenty-three patients with malignant stenosis or fistula were treated with SEMSs. The predominant histological type was squamous cell carcinoma (79.6%). A total of 282 partially covered and 41 fully covered SEMSs were inserted. Of the 323 patients, 182 did not received RT, 118 received RT before SEMS placement and 23 after. Comparing the group that received RT before stent insertion with the group that did not, the first one presented a higher frequency of severe pain (9/118 7.6% vs. 3/182 1.6%; P = 0.02). The group treated with RT after stent placement had a higher risk of global AEs (13/23 56.5% vs. 63/182 34.6%; P = 0.019), ingrowth/overgrowth (6/23 26.1% vs. 21/182 11.5%; P = 0.045) and gastroesophageal reflux (2/23 8.7% vs. 2/182 1.1%; P = 0.034). Treatment with RT before stent placement in patients with inoperable esophageal neoplasm prolongs survival and is associated with an increased risk of severe chest pain. Treatment with RT of patients with an esophageal stent increases the frequency of minor, not life-threatening AEs.

    Adverse events of self-expandable esophageal metallic stents in patients with long-term survival from advanced malignant disease
    (2017) MEDEIROS, Vitor Sousa; MARTINS, Bruno Costa; LENZ, Luciano; RIBEIRO, Maria Sylvia Ierardi; PAULO, Gustavo Andrade de; LIMA, Marcelo Simas; SAFATLE-RIBEIRO, Adriana Vaz; KAWAGUTI, Fabio Shiguehissa; PENNACCHI, Caterina; GEIGER, Sebastian N.; BASTOS, Victor R.; RIBEIRO-JUNIOR, Ulysses; SALLUM, Rubens A.; MALUF-FILHO, Fauze
    Background and Aims: Self-expandable metallic stents are considered the best palliative treatment of dysphagia for patients with advanced esophageal cancer. Adverse events (AEs) are a major concern, especially in patients with better prognosis and longer survival. The present study aimed to evaluate the AEs of patients who survived longer than 6 months with esophageal stents in place. Methods: This is a retrospective analysis of a prospectively collected database including all patients submitted to esophageal stent placement for the palliation of malignant diseases during the period from February 2009 to February 2014 at a tertiary care academic center who had stents longer than 6 months. Results: Sixty-three patients were included. Mean follow-up was 10.7 months. Clinical success was achieved in all patients, and the median stent patency was 7.1 months. AEs occurred in 40 patients (63.5%), totaling 62 AEs (mean, 1.5 AEs per patient). Endoscopic management of AEs was successful in 84.5% of cases, with a mean of 1.6 reinterventions per patient. The univariate analysis revealed that performance status, age, and post-stent radiotherapy presented a trend to higher risk of AEs. The multivariate analysis revealed that only performance status was associated with AEs (P = .025; hazard ratio, 4.1). Conclusions: AEs are common in patients with long-term esophageal stenting for malignancy. However, AEs were not related to higher mortality rate, and most AEs could be successfully managed by endoscopy. Only performance status was a risk factor for AEs. Our data suggest that metallic stenting is a valid option for the treatment of malignant esophageal conditions, even when survival longer than 6 months is expected.
