RESUMO
INTRODUCTION: The aim of this study was to compare the impact of the depth of myotomy (selective inner layer myotomy (SIM) vs. full-thickness myotomy (FTM)) on the outcome of patients treated with POEM for achalasia. METHODS: This was a retrospective, observational, conducted in two tertiary centers between October 2018 and September 2022. Patients were divided into two groups: SIM and FTM. The primary endpoint was clinical efficacy at 6 months, while secondary endpoints were postoperative criteria (such as pain, length of hospital stay, complications) and occurrence of gastroesophageal reflux disease (GERD) (esophagitis at 6 months, heartburn, and pH-metry). RESULTS: 158 patients were included in the study (33 in the FTM group and 125 in the SIM group). The success rates at 6 and 12 months were similar in both groups, with 84% and 70% in the SIM group versus 90% and 80% in the FTM group, respectively (p=0.57 and p=0.74). However, more opioid analgesics were consumed in the FTM group compared to the SIM group (41% vs 21%, p<0.01). The length of hospitalization was longer in the FTM group than in the SIM group (2.17 ± 2.62 vs 2.94 ± 2.33, p<0.001). The rate of esophagitis at 6 months was comparable (16% in the SIM group vs 12% in the FTM group, p=0.73). There was no significant difference in terms of heartburn at 6 or 12 months between the SIM and FTM groups (18.5% vs 3.8%, p=0.07 and 27% vs 12.5%, p=0.35, respectively). CONCLUSION: There was no significant difference in terms of clinical efficacy and GERD occurrence between FTM and SIM. However, full-thickness myotomy was associated with more postoperative pain and a longer length of hospital stay. Therefore, selective internal myotomy should be preferred over full-thickness myotomy.
RESUMO
BACKGROUND: Cancer patients near end of life (EOL) often suffer malnourishment and cachexia. In these patients, the prescription of parenteral nutrition (PN) remains highly controversial. Guidelines state that nutritional support does not improve quality of life in dying patients. We aimed to assess the compliance with international recommendations about PN prescription in advanced cancer, identify factors associated with PN at EOL and to evaluate the risk of blood stream infections (BSI). METHODS: Retrospective analysis of data from medical records of patients who died in 2013, 2015, 2017 and 2019 in a cancer center. RESULTS: One thousand two hundred and sixty patients with advanced cancer were included. PN was prescribed in 574 (45.6%) patients, the mean duration of PN was 10±9.7 days. Patients with a severe malnutrition [odds ratio (OR) =2.36; 95% confidence interval (CI): 1.42-4.02], a malignant bowel obstruction (MBO) (OR =2.25; 95% CI: 1.44-3.56), a length of hospitalization >12 days (OR =2.21; 95% CI: 1.67-2.94), a body mass index (BMI) <22.14 kg/m2 (OR =2.02; 95% CI: 1.52-2.67), an antitumor treatment (OR =1.58; 95% CI: 1.14-2.20) were more frequently prescribed a PN. BSI was diagnosed in 113 patients (9%) and was more frequent in patients receiving a PN (13% vs. 6%; OR =2.01; 95% CI: 1.18-3.54). CONCLUSIONS: International guidelines on PN in EOL cancer patients are poorly applied in the studied settings. Factors associated with the use of PN were low BMI, severe malnutrition, antitumor treatment, increased length of hospitalization. These findings argue for the use of a survival estimation tool and a multidisciplinary integrative care intervention when considering PN.
