Esophageal surgery has traditionally been associated with high morbidity rates. Despite the recent advances in the field of minimally invasive surgery and the introduction of enhanced recovery after surgery (ERAS) protocols, post-esophagectomy morbidity, especially that attributed to the respiratory system, remains a concern. In that respect, preoperative intensification of oral care or introduction of structured oral/dental hygiene regimens may lead to tangible postoperative benefits associated with reduced morbidity (respiratory or otherwise) and length of hospital stay. A systematic literature search of the Medline, Embase, Web of Knowledge and clinicaltrials.gov databases was undertaken for studies reporting use of preoperative oral/dental hygiene improvement regimens in patients scheduled to undergo esophagectomy for esophageal cancer. Meta-analysis was performed using a random-effects model. After screening 796 unique studies, seven were deemed eligible for inclusion in the meta-analysis. Pooled results indicated equivalent postoperative pneumonia rates in the oral pretreatment group and control groups (8.7 vs. 8.5%, respectively); however, the odds for developing pneumonia were reduced by 50% in the pretreatment group (odds ratio 0.5, 95% C.I. 0.37 to 0.69, P < 0.001). No statistically significant difference was detected in the anastomotic leak (odds ratio 0.93, 95% C.I. 0.38 to 2.24, P = 0.87) and length of stay outcomes (mean difference 0.63, 95% C.I. -3.22 to 4.47, P = 0.75). Oral/dental pretreatment reduces the odds for developing post-esophagectomy pneumonia. This finding should be cautiously interpreted given the significant limitations inherent in this meta-analysis. Further investigation via well-designed clinical trials is thus warranted before implementation in routine practice can be recommended., (© The Author(s) 2022.

Oncologic patients often suffer from malnutrition, which might negatively affect treatment outcomes. Global Leadership Initiative on Malnutrition (GLIM)-based malnutrition is associated with short- and long-term outcomes in cancer patients. The aim of the current meta-analysis was to determine the impact of GLIM-defined malnutrition on postoperative complications and survival in esophageal and gastric cancer patients. A systematic search was conducted to identify studies published until February 2022 that assessed the association between GLIM criteria and short- and long-term outcomes in esophageal and gastric cancer patients. We included seven observational studies reporting on a total of 3662 patients with esophageal and gastric cancer. GLIM-defined malnutrition was associated with increased overall complications (pooled HR 2.58, 95% CI 1.45-4.59, p  = 0.001). Malnutrition was significantly associated with decreased overall survival (pooled HR 1.63, 95% CI 1.18-1.84, p  = 0.003) as well as with decreased disease-free survival (pooled HR 1.78, 95% CI 1.36-2.33, p  < 0.0001). GLIM-based malnutrition was associated with an increased risk for developing postoperative complications and impaired survival of esophageal and gastric cancer patients. Our findings support the use of GLIM criteria in clinical practice as a relatively simple and reliable tool for assessing the nutritional status of oncologic patients.

Objective: Disease-related malnutrition is a debilitating condition frequently observed in patients with cancer. The aim of the current study was to prospectively examine postoperative changes in nutritional and functional status of patients undergoing surgery for gastric, esophageal, and gastroesophageal junction cancer., Methods: Participants were prospectively recruited from September 2015 to September 2019. The assessment of malnutrition was based on the Patient-Generated Subjective Global Assessment tool. The functional assessment included the evaluation of muscle strength and physical performance, while muscle mass assessment was based on Skeletal Muscle Mass Index (SMI) derived from the analysis of computed tomography scans. The follow up of patients was scheduled at six months postoperatively., Results: A total of 98 patients were analyzed. Mean patient age was 60.79 ± 10.19 years and 80.6% were males. The mean unintentional weight loss at 6 months was 11.7 ± 8.0%. Patients who underwent McKeown esophagectomy reported the greatest weight loss postoperatively (16.2 ± 9.6%), whereas the lowest rate of weight loss was observed in patients who underwent partial gastrectomy (5.6 ± 6.7%). The rate of severe malnutrition declined at six months postoperatively (39.7% vs 27%). Muscle strength and physical performance were significantly deteriorated at 6 months postoperatively, except for the group of partial gastrectomy, while SMI significantly decreased in all groups of patients except for McKewon esophagectomy group. Finally, the prevalence of low muscle mass increased significantly from 43.5% in the preoperative period to 66.7% at the follow-up., Conclusions: Our study revealed a significant deterioration in gastroesophageal cancer patient nutritional and functional status at six months postoperatively. The high prevalence of malnutrition and low muscle mass requires systematic follow-up and multidirectional monitoring in order to ensure the successful rehabilitation of these patients.

Malnourished patients undergoing esophagectomy have increased risk of postoperative complications. The aim of the current study was to identify nutritional and functional risk factors for postoperative complications in patients with esophageal and gastroesophageal junction cancer who underwent esophagectomy. Seventy patients who were admitted at the First Department of Surgery, Laikon General Hospital, Athens, Greece, were included in this study. Laboratory data and data regarding nutritional and functional status were recorded preoperatively. Postoperative complications were graded according to Clavien-Dindo classification. Thirty-seven patients (52.9%) developed postoperative complications. Albumin and Geriatric Nutritional Risk Index (GNRI) levels were lower in patients who developed major complications compared to patients who did not develop postoperative complications (3.90 ± 0.44 vs 4.18 ± 0.37 g/dL, p  = 0.014 and 107.40 ± 15.76 vs 114.98 ± 12.26, p  = 0.050 respectively). Major complications were associated with higher percentage of weight loss (12.1 ± 11.1 vs 6.2 ± 7.5%, p  = 0.019) and with low handgrip strength (80 vs 16.9%, p  = 0.006). Albumin (3.93 ± 0.18 vs 4.15 ± 0.41 g/dL, p  = 0.019) and low muscle mass (22.6 vs 2.8%, p  = 0.016) were significantly associated with anastomotic leakage occurence. The incorporation of patients' nutritional and functional status in the preoperative risk assessment might increase prognostic ability concerning postoperative complications of patients undergoing esophagectomy.

Objective: Malnutrition is common in patients who underwent upper gastrointestinal cancer surgery. Our goal was to explore postoperative compliance with oral nutritional supplementation and define barriers to consumption in patients with esophageal, gastroesophageal junction, and gastric cancer.Methods: Participants were prospectively recruited from September 2015 to November 2018. Preoperative nutritional status was assessed using the Patient Generated Subjective Global Assessment. Malnourished patients and patients at risk for malnutrition were offered oral nutritional supplementation at the time of hospital discharge. Compliance was evaluated 1 month after hospital discharge.Results: A total of 78 patients were analyzed. Mean patient age was 62.8 ± 10.7 years and 83.3% were males. Εsophagectomy and gastrectomy were performed in 60.3% and 39.7% of the patients respectively. Twenty-eight (35.9%) participants reported consuming all prescribed supplements, whereas 50 (64.1%) patients were noncompliant with their prescribed oral nutritional supplementation regimen. The main barriers to oral nutritional supplementation compliance were bloating (compliant vs. noncompliant patients: 17.9% vs. 58%, p < 0.001), early satiety (compliant vs. noncompliant patients: 25% vs. 52.32%, p < 0.001), flavor or texture dislike (compliant vs. noncompliant patients: 7.1% vs. 34%, p < 0.001), and diarrhea (compliant vs. noncompliant patients: 10.7% vs. 24%, p < 0.001). No other statistically significant differences were identified between the two groups.Conclusions: Postoperative compliance to oral nutritional supplementation is low in patients who underwent upper gastrointestinal cancer surgery. Patient education and support as well as providing a range of oral nutrition supplement flavors, texture, and compositions may be useful in increasing adherence to oral nutritional supplementation regimens.
