A systematic review of the nutritional consequences of esophagectomy

Oral nutritional supplements improve clinical outcomes and are cost-effective for hospitalized patients in China

OBJECTIVE

This study assessed the therapeutic benefits and modeled the cost-effectiveness of oral nutritional supplements (ONS) in China.

METHODS

Data were collected from 27 152 adult inpatients between January 1, 2018, and December 31, 2020. Propensity score matching was used for balancing the baseline characteristics between the ONS group and non-ONS group. A decision-tree model was developed to assess the cost-effectiveness of ONS for patients with nutritional risk, and the incremental cost-effectiveness ratio was the metric to determine the most cost-effective strategy. One-way sensitivity and probabilistic sensitivity analyses were conducted to assess the model's stability. In addition, subgroup analysis was conducted based on clinical characteristics. Differences in clinical outcomes between the groups were compared using Student's t test, Mann-Whitney U test, or chi-square test.

RESULTS

The ONS group displayed significantly lower levels of prealbumin, albumin, hemoglobin, and BMI than the non-ONS group at admission. The incidence of malignant tumors, intestinal obstruction, and inflammatory bowel disease was significantly higher in the ONS group than the non-ONS group. The ONS group had a significantly higher effective rate than the non-ONS group (51.7% versus 50.3%, P < 0.05). Analysis of the decision-tree model revealed that the ONS group experienced an increase in cost of 19 850.96 yuan but achieved an additional 1.3406 effectiveness rate, resulting in an incremental cost-effectiveness ratio of 14 807.51, which fell below China's 2020 per capita gross domestic product of 71 965 yuan. Sensitivity analysis further confirmed the robustness of the model.

CONCLUSIONS

ONS are demonstrated a high rate of efficacy, although patients currently using ONS are typically in a severe disease state. In addition, ONS is cost-effective. We suggest that the reimbursement coverage of ONS be expanded to include in-hospital patients who are at high nutritional risk.

Clinical impact of postoperative changes in body composition on long-term outcomes in patients with esophageal cancer

BACKGROUND & AIMS

This study aimed to investigate the temporal changes in body composition following esophagectomy in patients with esophageal cancer using bioelectrical impedance analysis and to assess the prognostic implications of these changes.

METHODS

Our study included 528 patients who underwent esophagectomy and preoperative body composition measurements between January 2013 and June 2020. Postoperative body composition was measured in 493 patients at discharge as follows: 184 at 1 month, 144 at 2 months, 143 at 3 months, 103 at 6 months, 58 at 9 months, and 78 at 12 months.

RESULTS

Body weight (BW) continuously decreased until the 6 postoperative months (POMs), reaching -11.5% compared with preoperative levels. Subsequently, almost no change was observed at 12 POMs. Skeletal muscle mass (SMM) decreased until 3 POMs but gradually recovered after 3 POMs. Conversely, body fat mass (BFM) consistently decreased over time post-esophagectomy. The patients were categorized into moderate (>-10%) and severe (≤-10%) groups based on % BW, % SMM, and % BFM losses at 3 POMs. Severe SMM loss at 3 POMs correlated with reduced overall survival (OS) (3-year OS: 85.9% in moderate vs. 75.1% in severe, p = 0.035). BFM loss was associated with reduced recurrence-free survival (3-year RFS: 83.3% in moderate vs. 62.0% in severe, p = 0.011). Multivariate analysis identified pStages Ⅲ and Ⅳ, % SMM loss ≤ -10%, and % BFM loss ≤ -10% as independent factors for worse OS.

CONCLUSION

Post-esophagectomy, distinct temporal changes in BW, SMM, and BFM are observed. Significant reductions in SMM and BFM 3 POMs indicate a poor long-term prognosis.

Micronutrient deficiencies and anemia in the follow-up after gastroesophageal cancer surgery

Due to insufficient dietary intake and altered digestion and absorption of nutrients, patients after gastroesophageal cancer surgery are at risk of becoming malnourished and consequently develop micronutrient deficiencies. The aim of this study was to determine the prevalence of micronutrient deficiencies and anemia during follow-up after gastroesophageal cancer surgery. This single-center cross-sectional study included patients after resection for esophageal or gastric cancer visiting the outpatient clinic in 2016 and 2017. Only patients without signs of recurrent disease were included. All patients were guided by a dietician in the pre- and postoperative phase. Dietary supplements or enteral tube feeding was prescribed in case of inadequate dietary intake. Blood samples were examined for possible deficiencies or abnormalities in hemoglobin, prothrombin time, iron, ferritin, folic acid, calcium, zinc, vitamin A, vitamin B1, vitamin B6, vitamin B12, vitamin D and vitamin E. The percentage of patients with micronutrient deficiencies were scored. Of the 335 patients visiting the outpatient clinic, measurements were performed in 263 patients (221 after esophagectomy and 42 after gastrectomy), resulting in an inclusion rate of 79%. In the esophagectomy group, deficiencies in iron (36%), vitamin D (33%) and zinc (20%) were most prevalent. After gastric resection, deficiencies were most frequently observed in vitamin D (52%), iron (33%), zinc (28%) and ferritin (17%). Low levels of hemoglobin were found in 21% of patients after esophagectomy and 24% after gastrectomy. Despite active nutritional guidance, deficiencies in vitamin D, iron, zinc and ferritin, as well as low levels of hemoglobin, are frequently observed following gastroesophageal resection for cancer. These micronutrients should be periodically checked during follow-up and supplemented if needed.

Frailty and Health-Related Quality of Life in Elderly Patients Undergoing Esophageal Cancer Surgery: A Longitudinal Study

PURPOSE

This study aims to elucidate the longitudinal alterations in frailty and health-related quality of life experienced by elderly patients undergoing surgical treatment for esophageal cancer. Additionally, it seeks to ascertain the impact of preoperative frailty on postoperative health-related quality of life over time.

METHODS

131 patients were included in the prospective study. Patients' frailty and health-related quality-of-life were assessed utilizing the Tilburg and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 at preoperative, 1 week, 1 month, and 3 months, postoperatively. Statistical analyses were performed using generalized estimating equations, repeated-measures analysis of variance, and linear mixed models (LMMs).

RESULTS

Out of 131 patients, 28.2% had frailty before surgery, and the prevalence of frailty consistently higher after surgery compared with baseline (67.9%, 51.9%, and 39.7%). There was no significant change in frailty scores in preoperative frail patients within 3 months following surgery (p = .496, p < .999, p < .999); whereas in preoperative non-frail patients, the frailty scores increased at 1 week (p < .001) and then decreased at 1 month (p = .014), followed by no change at 3 months. In addition, preoperative frail patients had significantly worse global quality-of-life (β = -4.24 (-8.31; -.18), p = .041), physical functioning (β = -9.87 (-14.59; -5.16), p < .001), role functioning (β = -10.04 (-15.76; -4.33), p = .001), and social functioning (β = -8.58 (-15.49; -1.68), p = .015), compared with non-frail patients.

CONCLUSIONS

A significant proportion of participants exhibited a high prevalence of preoperative frailty. These patients, who were preoperatively frail, exhibited a marked reduction in health-related quality-of-life, a more gradual recovery across various functional domains, and an increased symptom burden during the follow-up period. Therefore, it is crucial to meticulously identify and closely monitor patients with preoperative frailty for any changes in their postoperative physiology, role, and social functioning.

Exocrine pancreatic insufficiency and pancreatic exocrine replacement therapy in clinical practice

Exocrine pancreatic insufficiency (EPI) is a complex condition that disrupts normal digestion and absorption. Patients with EPI may suffer from mild to debilitating malabsorption with a constellation of symptoms that can have a significant effect on quality of life and nutrition status. Pancreatic enzyme replacement therapy (PERT) is effective and safe to treat EPI and is the standard of care for this condition. A wide variety and various forms of these products exist, as well as numerous guidelines and recommendations. Obtaining PERT for patients can oftentimes be cost prohibitive. Determining the presence and extent of EPI can be challenging and patient specific, making it difficult for practitioners. This narrative review will explore these issues, as well as several disease states potentially affected by EPI, and review current management strategies.

Dietary habits and nutrition status in esophageal cancer patients after esophageal reconstruction

Background

Surgery is the cornerstone of the treatment of esophageal cancer (EC). This study is to evaluate the dietary habits and nutrition status in EC patients who underwent esophagectomy followed by esophageal reconstruction.

Methods

This retrospective study included patients with EC who underwent esophagectomy followed by esophageal reconstruction in the Department of Thoracic Surgery I of Peking University Cancer Hospital between February 2014 and December 2018. The primary outcomes were dietary habits and nutrition status. The secondary outcomes were gastrointestinal symptoms and quality of life (QoL).

Results

A total of 346 patients were included. At 30 months after the operation, 90.2% of the patients had recovered to regular dietary habits, 72.8% of patients had a restored frequency of preoperative regular food intake, 2.3% of the patients ate more than six times a day, and 0.6% had semi-liquid food because of bad teeth. The nutrition status remained stable after 6 months postoperatively and recovered slightly 1 year after the surgery. At 30 months after the operation, the most common gastrointestinal symptoms were reflux (38.4%), dysphagia (15.3%), hoarseness (11.8%), abdominal distension (6.6%), diarrhea (2.9%), and nausea and vomiting (2.3%). According to the European Organization for Research and Treatment of Cancer, Quality of Life Questionnaire-OG 25 (EORTC QLQ-OG 25), the factors that affected the life quality of patients during follow-up were anxiety, reflux, and dietary limitations.

Conclusions

Most patients with EC who underwent esophageal reconstruction recovered to regular dietary habits and stable nutrition status, while some may still suffer from gastrointestinal symptoms, anxiety, and dietary limitations.

The impact of jejunostomy feeding on nutritional outcomes after oesophagectomy

BACKGROUND

Nutritional status is compromised long-term following oesophagectomy. Controversy surrounds the optimal route for nutrition support postoperatively and there is wide variation in the use of feeding jejunostomy tubes.

METHODS

A retrospective service evaluation was conducted for all consecutive adults who underwent oesophagectomy for a cancer diagnosis within a specialist centre between April 2016 and July 2019 (n = 165). Nutritional and clinical outcomes were compared for patients who received jejunostomy feeding (n = 24), versus those who did not (n = 141).

RESULTS

Patients with feeding jejunostomy lost significantly less weight at both 6 and 12 months postoperatively compared to those without jejunostomy (p ≤ 0.001 and p = 0.001, respectively). This remained statistically significant in multiple regression, controlling for age, gender, preoperative tumour staging and adjuvant treatment (p ≤ 0.001 and p = 0.03, respectively). Median length of home enteral feeding was 10 weeks after discharge in the jejunostomy group. We observed minor jejunostomy tube-related complications in four patients (16.7%). Of those readmitted within 90 days of surgery in the non-jejunostomy group, nutritional failure was a factor in 43.2% of these readmissions. "Rescue tube feeding" was required by 8.5% of the non-jejunostomy group within the first postoperative year, including 6.4% within 90 days of surgery.

CONCLUSIONS

Use of short-term supplementary jejunal feeding in addition to oral intake after hospital discharge is beneficial for maintaining weight after oesophagectomy. We suggest a future randomised-controlled trial to confirm these findings.

Nutritional care in patients undergoing laparoscopic/minimally invasive surgeries for gastrointestinal tumours

The introduction of minimally invasive surgeries for gastrointestinal tumours has been associated with many favourable postoperative outcomes and a reduced impact on nutritional status. The literature review begins by discussing the impact of minimally invasive procedures on the nutritional status of patients with gastrointestinal tumours, followed by indications for enteral nutrition (EN) in this population, including preoperative nutritional support and postoperative nutritional support. The review then examines the evidence that favours the use of EN in this population, including studies demonstrating improved outcomes with preoperative EN and reduced postoperative complications with postoperative EN. It also discusses potential strategies for improving outcomes with EN, such as early initiation of feeding and individualized nutrition plans. Overall, current evidence shows that EN improves outcomes, reduces complications, and enhances the quality of life. However, the optimal timing, composition of EN, and long-term outcomes are still unclear, indicating the need for future investigations.

Perioperative nutritional assessment and support in visceral surgery

Malnutrition in visceral surgery is frequent; it calls for screening prior to an operation, and its postoperative occurrence should be sought out and prevented, if possible. Organization of an individualized nutritional support strategy is based on systematic nutritional assessment and adapted to the type of surgery, the objectives being to forestall malnutrition and to reduce induced morbidity (immunosuppression, delayed wound healing, anastomotic fistulas…). Nutritional support is part and parcel of enhanced recovery after surgery (ERAS), and has shown effectiveness in the field of visceral surgery. Oral feeding should always be privileged to the greatest possible extent, complemented if necessary by nutritional supplements. If nutritional support is required, enteral nutrition should be favored over parenteral nutrition. As for the role of pharmaco-nutrition or immuno-nutrition, it remains ill-defined. Lastly, each type of visceral surgery entails specific modifications of the anatomy of the digestive system and is liable to have specific functional consequences, which should be known and taken into account in view of effectively tailoring nutritional support.

Optimizing Nutritional Status of Patients Prior to Major Surgical Intervention

In patients undergoing elective cardiovascular and thoracic surgery, malnutrition and the deterioration of nutritional status are associated with negative outcomes. Recognition of the contributory factors and the complications stemming from surgical stress is important for the prevention and management of these patients. We have reviewed the literature available and focused on the nutritional and metabolic aspects affecting surgical patients, with emphasis on the recommendations of enhanced recovery protocols. The implementation of enhanced recovery protocols and nutritional support guidelines focusing on the surgical patient as part of a multidisciplinary approach would improve the nutritional status of surgical patients at risk for negative outcomes.

Vitamin insufficiency after surgery for oesophagogastric neoplasms: a study protocol for a prospective intervention study

INTRODUCTION

Oesophageal cancer (EC) and gastric cancer (GC) are among the top 10 cancers worldwide. Both diseases impact the nutritional status of patients and their Quality of Life (QoL). Preoperative malnutrition is reported in 42%-80%. However, studies investigating postoperative nutritional status are limited, and postoperative identification and treatment of micronutrient and macronutrient deficiencies are currently lacking in (inter-)national guidelines. The aim of this study is to identify and target micronutrient deficiencies after surgery for oesophagogastric neoplasms.

METHODS

This is a single-centre prospective intervention trial performed in Zuyderland Medical Centre. 248 patients who underwent oesophagectomy (n=124) or (sub)total gastrectomy (n=124) from 2011 until 2022 will be included. Both groups will receive Calcium Soft Chew D3 and a multivitamin supplement (MVS) specifically developed according to the type of operation patients underwent; the oesophagectomy group will receive Multi-E and the gastrectomy group will receive Multi-G. The MVSs will be taken once daily and Calcium Soft Chew D3 two times per day. Supplementation will start after baseline measurements. At baseline (T0), blood withdrawal for micronutrient analysis and faecal elastase-1 analysis for exocrine pancreatic insufficiency (EPI) will be performed. Additionally, patients will receive questionnaires regarding QoL and dietary behaviour. After 180 days of supplementation (T1), baseline measurements will be repeated, and the supplement tolerance questionnaire will be completed. Measurements will also be conducted after 360 days (T2) and after 720 days (T3) of supplementation. The main study parameter is micronutrient deficiency (yes/no) for all measurements. Secondary parameters include occurrence of EPI (n, %), diarrhoea (n, %), steatorrhoea (n, %) or bloating (n, %), time between surgery and start of supplementation (mean in months), and QoL at all time points.

ETHICS AND DISSEMINATION

The study was approved by the Zuyderland Medical Centre Ethics Committee, Heerlen, the Netherlands. The findings will be disseminated through scientific congresses and in peer-reviewed journals.

The effect of post-discharge oral nutritional supplements on outcomes after gastrointestinal surgery: A systematic review and meta-analysis

BACKGROUND

Malnutrition is a risk-factor for adverse postoperative outcomes. This systematic review and meta-analysis evaluated the impact of post-discharge oral nutritional supplements (ONS) on outcomes in patients undergoing gastrointestinal surgery.

METHODS

The Medline and Embase databases were searched for randomised clinical trials in patients undergoing gastrointestinal surgery who had received ONS for at least two weeks after discharge from hospital. The primary endpoint was weight change. Secondary endpoints included quality of life, total lymphocyte count, total serum protein and serum albumin. Analysis was performed using RevMan5.4 software.

RESULTS

Fourteen studies with 2480 participants (1249 ONS/1231 controls) were included. Pooling of results revealed that a reduction in postoperative weight loss in patients taking ONS, when compared with control: overall weighted mean difference (WMD) -1.69 kg, 95% CI -2.98 to -0.41, P = 0.01. Serum albumin concentration was increased in the ONS group: WMD = 1.06 g/L, 95% CI 0.04 to 2.07, P = 0.04. Haemoglobin was also increased: WMD = 2.91 g/L, 95% CI 0.58 to 5.25, P = 0.01. Total serum protein, total lymphocyte count, total cholesterol and quality of life did not differ between the groups. Patient compliance was relatively poor across the studies and there was variability in the composition of ONS, volume consumed and surgical procedures performed.

CONCLUSIONS

There was a reduction in postoperative weight loss and an improvement in some biochemical parameters in patients receiving ONS after gastrointestinal surgery. Future RCTs with more consistent methodologies are needed to investigate the efficacy of ONS after discharge from hospital following gastrointestinal surgery.

PYloroplasty versus No Intervention in GAstric REmnant REconstruction after Oesophagectomy: study protocol for the PYNI-GAREREO phase III randomized controlled trial

BACKGROUND

After esophagectomy for esophageal and esophagogastric cancer, more than half of patients have lost > 10% of their body weight at 12 months. In most cases, the gastric remnant is used for reconstruction after esophagectomy. One of the most serious nutritional complications of this technique is delayed gastric emptying caused by gastric remnant mobilization and denervation of the vagus nerve. The aim of the PYloroplasty versus No Intervention in GAstric REmnant REconstruction after Oesophagectomy (PYNI-GAREREO) trial is to analyze the clinical outcome of modified Horsley pyloroplasty (mH-P) as a method of preventing delayed gastric emptying.

METHODS

The PYNI-GAREREO trial is designed as an open randomized, single-center superiority trial. Patients will be randomly allocated to undergo gastric remnant reconstruction with mH-P (intervention group) or no intervention (control group) in parallel groups. All patients with esophageal cancer or esophagogastric cancer planning to undergo curative minimally invasive esophagectomy will be considered for inclusion. A total of 140 patients will be included in the study and randomized between the groups in a 1:1 ratio. The primary outcome is the body weight change at 6 months postoperatively, and the secondary outcomes are the nutritional status, postoperative complications, functional outcome, and quality of life until 1 year postoperatively.

DISCUSSION

We hypothesize that mH-P after minimally invasive esophagectomy more effectively maintains patients' nutritional status than no pyloroplasty.

The Impact of Acute Systemic Inflammation Secondary to Oesophagectomy and Anastomotic Leak on Computed Tomography Body Composition Analyses

This study aimed to longitudinally assess CT body composition analyses in patients who experienced anastomotic leak post-oesophagectomy. Consecutive patients, between 1 January 2012 and 1 January 2022 were identified from a prospectively maintained database. Changes in computed tomography (CT) body composition at the third lumbar vertebral level (remote from the site of complication) were assessed across four time points where available: staging, pre-operative/post-neoadjuvant treatment, post-leak, and late follow-up. A total of 20 patients (median 65 years, 90% male) were included, with a total of 66 computed tomography (CT) scans analysed. Of these, 16 underwent neoadjuvant chemo(radio)therapy prior to oesophagectomy. Skeletal muscle index (SMI) was significantly reduced following neoadjuvant treatment (p < 0.001). Following the inflammatory response associated with surgery and anastomotic leak, a decrease in SMI (mean difference: -4.23 cm²/m², p < 0.001) was noted. Estimates of intramuscular and subcutaneous adipose tissue quantity conversely increased (both p < 0.001). Skeletal muscle density fell (mean difference: -5.42 HU, p = 0.049) while visceral and subcutaneous fat density were higher following anastomotic leak. Thus, all tissues trended towards the radiodensity of water. Although tissue radiodensity and subcutaneous fat area normalised on late follow-up scans, skeletal muscle index remained below pre-treatment levels.

Early postoperative weight loss is associated with poor prognosis in patients with esophageal cancer

BACKGROUND

Surgery for esophageal cancer (EC) causes morphological and functional changes in the upper gastrointestinal tract, resulting in postoperative weight loss (PWL). PWL has been shown to lead to poor nutritional status and immunocompetence, which may worsen the prognosis for several types of cancer. However, few reports have examined the relationship between weight loss (WL) in the early postoperative period and cancer prognosis.

METHODS

A total of 421 esophageal cancer patients underwent curative esophagectomy at Osaka University Hospital from 2010 to 2016. Based on the patients' body weight 1.5 months after surgery, they were classified into severe WL (n = 50) and slight-moderate WL (n = 371) groups.

RESULTS

The 5-year overall survival (OS), cancer-specific survival (CSS), and recurrence-free survival (RFS) were significantly lower in the severe WL group than the slight-moderate WL group (p = 0.0002, p < 0.0001, and p = 0.0004, respectively). In the multivariate analysis, tumor invasion depth (pT3, 4), lymph node metastasis (pN2, 3), preoperative Prognostic Nutrition Index (< 45), postoperative complications (≥ G3), and severe WL were independent prognostic factors for CSS (hazard ratio [HR] 2.5, 95% confidence interval [CI] 1.7-3.7; HR 1.6, 95% CI 1.1-2.4; HR 1.9, 95% CI 1.3-2.8; HR 1.6, 95% CI 1.1-2.4; and HR 2.7, 95% CI 1.7-4.2, respectively). In a multivariate analysis of risk factors leading to severe WL, thoracotomy (VATS) and postoperative MAX CRP (high) were independent risk factors (odds ratio [OR 0.48, 95% CI 0.24-0.97; OR 1.9, 95% CI 1.0-3.5).

CONCLUSION

Early PWL would be a useful marker of poor cancer prognosis in EC patients. Highly inflammatory conditions due to surgical invasion and postoperative complications may contribute to early PWL.

Postoperative Nutrition Management: Who Needs What?

Background

Early oral feeding after major abdominal surgery has been clearly shown to be safe and not a risk factor for anastomotic dehiscence. Within the Enhanced Recovery after Surgery protocol, it is the nutritional plan A. Nonetheless, one must consider that postoperative protein and energy requirements will often be not covered by oral food intake alone. Because nutritional status has been shown to be a prognostic factor in patients undergoing major abdominal surgery, the preoperative identification of patients at risk may be mandatory. Malnutrition may be underestimated in an overweight society. With special regard to patients with cancer and those with preexisting malnutrition, an accumulating caloric gap may be harmful in the early and late postoperative periods. Furthermore, complications requiring reoperation and intensive care treatment may occur.

Summary

Therefore, a plan B for postoperative nutrition therapy is needed, using preferentially the enteral route. The European Society for Clinical Nutrition and Metabolism recently addressed perioperative nutritional management and the indications for enteral and even parenteral supplementation to achieve caloric requirements in the postoperative course. In the first months after surgery, persisting weight loss is common in patients with upper gastrointestinal resections, even in those with an uncomplicated course. This may delay the initiation of adjuvant chemotherapy, increase toxicity, and worsen long-term outcomes.

Minimally invasive surgical techniques for oesophageal cancer and nutritional recovery: a prospective population-based cohort study

OBJECTIVES

To explore whether the minimally invasive oesophagectomy (MIE) or hybrid minimally invasive oesophagectomy (HMIE) are associated with better nutritional status and less weight loss 1 year after surgery, compared with open oesophagectomy (OE).

DESIGN

Prospective cohort study.

SETTING

All patients undergoing oesophagectomy for cancer in Sweden during 2013-2018.

PARTICIPANTS

A total of 424 patients alive at 1 year after surgery were eligible, and 281 completed the 1-year assessment. Of these, 239 had complete clinical data and were included in the analysis.

PRIMARY AND SECONDARY OUTCOME MEASURES

The primary outcome was nutritional status at 1 year after surgery, assessed using the abbreviated Patient-Generated Subjective Global Assessment questionnaire. The secondary outcomes included postoperative weight loss at 6 months and 1 year after surgery.

RESULTS

Of the included patients, 78 underwent MIE, 74 HMIE while 87 patients underwent OE. The MIE group had the highest prevalence of malnutrition (42% vs 22% after HMIE vs 25% after OE), reduced food intake (63% vs 45% after HMIE vs 39% after OE), symptoms reducing food intake (60% vs 45% after HMIE vs 60% after OE) and abnormal activities/function (45% vs 32% after HMIE vs 43% after OE). After adjustment for confounders, MIE was associated with a statistically significant increased risk of reduced food intake 1 year after surgery (OR 2.87, 95% CI 1.47 to 5.61), compared with OE. Other outcomes were not statistically significantly different between the groups. No statistically significant associations were observed between surgical techniques and weight loss up to 1 year after surgery.

CONCLUSIONS

MIE was statistically significantly associated with reduced food intake 1 year after surgery. However, no differences were observed in weight loss between the surgical techniques. Further studies on nutritional impact of surgical techniques in oesophageal cancer are needed.

Home enteral nutrition for patients with esophageal cancer undergoing esophagectomy: A systematic review and meta-analysis

Introduction

Home enteral nutrition (HEN) is a relatively new nutritional intervention that provides patients with EN support at home through jejunostomy or nasogastric feeding tubes. We conducted this systematic review and meta-analysis to explore the safety and effect of HEN compared with normal oral diet (NOD) in postoperative patients with esophageal cancer (EC).

Methods

EMBASE, Medline, Web of Science, and the Cochrane Library were used to search articles in English-language journals. The intervention effect was expressed using risk ratios (RRs) for dichotomous outcomes and mean differences (MDs) for continuous outcome measures, with 95% confidence intervals (95% CIs). The chi-square test and I-square test were used to test heterogeneity among studies.

Results

Four studies were eventually included in this meta-analysis. Compared with NOD, HEN has a favorable impact on postoperative body mass index (BMI) (weighted mean difference [WMD] = 0.70, 95% CI: 0.09–1.30, P = 0.02), lean body mass (LBM) (WMD = 0.76, 95% CI: 0.04–1.48, P = 0.04), and appendicular skeletal muscle mass index (ASMI) (WMD = 0.30, 95% CI: 0.02–0.58, P = 0.03). Physical function (WMD = 9.26, 95% CI: 8.00–10.53, P < 0.001), role function (WMD = 9.96, 95% CI: 8.11–11.82, P < 0.001), and social function (WMD = 8.51, 95% CI: 3.48–13.54, P = 0.001) of the HEN group were better than those of the NOD group at 3 months, and HEN could reduce the fatigue of patients (WMD = −12.73, 95% CI: −14.8 to −10.66, P < 0.001) and the incidence of postoperative pneumonia (RR = 0.53, 95% CI: 0.34–0.81, P = 0.004). There was no significant difference in albumin between HEN and NOD groups (WMD = 0.05, 95% CI: −0.03 to 0.13, P = 0.20).

Conclusion

HEN improved nutritional status and quality of life (QOL) in postoperative patients with EC and reduced fatigue and the incidence of postoperative pneumonia. All in all, the results of our meta-analysis support the use of HEN after esophagectomy.

Vitamin B12 supplementation post-gastrectomy: a service closed-loop audit at St. James's Hospital, Dublin

Background

Vitamin B₁₂ (VB12) deficiency is a well-described complication post-gastrectomy. It is caused by the loss of parietal cell mass leading to megaloblastic anaemia. This closed-loop audit assesses patient understanding of and adherence with VB12 supplementation guidelines post-gastrectomy.

Methods

A closed-loop audit cycle was performed. After the first cycle, an educational intervention was actioned prior to re-audit. One hundred twenty-five patients who underwent gastrectomy between 2010 and 2020 were available for study (86 total gastrectomies (TG), 39 subtotal gastrectomies (STG)). Twenty-nine patients who had not been adherent with VB12 supplementation/surveillance were eligible for re-audit.

Results

91.9% (79/86) of TG patients reported adherence in regular parenteral VB12 supplementation. Adherence was significantly lower for STG for checking (and/or replacing) their VB12, with only 53.8% (21/39) checking their VB12 levels. 67/125 (53.6%) of the patients stated that they knew it was important to supplement B₁₂ post-gastrectomy. 37.8% (43/113) of participants could explain why this was important, and 14.4% (18/125) had any knowledge of the complications of VB12 deficiency. Following re-audit, 5/8 (57.5%) of TG patients who had not been adherent with VB12 supplementation in the first cycle were now adherent with VB12 supplementation following our educational intervention. 7/17 (41.2%) of the STG group had received VB12 or made arrangements to receive supplemental VB12 if it was indicated.

Conclusion

This study demonstrates good adherence in those undergoing TG. Patient understanding correlates with adherence, suggesting that patient education and knowledge reinforcement may be key to adherence with VB12 supplementation. A simple educational intervention can improve adherence with VB12 supplementation in patients undergoing gastrectomy.

Incidence, Diagnosis and Management of Malabsorption Following Oesophagectomy: a Systematic Review

BACKGROUND

Survival following oesophagectomy for cancer is improving, resulting in increased focus on quality of life and survivorship. Malabsorption syndrome is multifactorial and includes exocrine pancreatic insufficiency (EPI), small intestinal bacterial overgrowth (SIBO) and bile acid malabsorption (BAM). The aim of this study was to evaluate the reported incidence and management of malabsorption syndromes post-oesophagectomy.

METHODS

A systematic search of PubMed, EMBASE, MEDLINE, Scopus and the Cochrane Library evaluating incidence, diagnosis and management of malabsorption was performed for studies published until December 2021.

RESULTS

Of 464 identified studies, eight studies (n = 7 non-randomised longitudinal studies) were included where patients were identified with malnutrition following oesophagectomy. Studies included a combined sample of 328 (range 7-63) patients. Malabsorption syndromes including EPI, SIBO and BAM occurred in 15.9-100%, 37.8-100% and 3.33-100% over 21 days-60 months, 1-24 months and 1-24 months respectively. There was no consensus definition for EPI, SIBO or BAM, and there was variation in diagnostic methods. Diagnostic criteria varied from clinical (gastrointestinal symptoms or weight loss), or biochemical (faecal elastase, hydrogen breath test and Selenium-75-labelled synthetic bile acid measurements). Treatment modalities using pancreatic enzyme replacement, rifaximin or colesevelam showed improvement in symptoms and weight in all studies, where investigated.

CONCLUSIONS

Malabsorption syndromes following oesophagectomy are under-recognised, and thus under-reported. The resultant gastrointestinal symptoms may have a negative effect on post-operative quality of life. Current literature suggests benefit with outlined therapies; however, greater understanding of these conditions, their diagnosis and management is required to further understand which patients will benefit from treatment.

Unresolved issues in perioperative nutrition: A narrative review

Surgical patients are at an increased risk of negative outcomes if they are malnourished or at risk of malnutrition preoperatively. Optimisation of nutritional status should be a focus throughout the perioperative continuum to promote improved surgical outcomes. Enhanced Recovery after Surgery (ERAS) protocols are increasingly applied in the surgical setting but are not yet widespread. This narrative review focused on areas of perioperative nutrition that are perceived as controversial or are lacking in agreement. A search for available literature was conducted on 1 March 2022 and relevant high-quality articles published since 2015 were considered for inclusion. Most malnutrition screening tools are not specific to the surgical population except for the Perioperative Nutrition Screen (PONS) although more large-scale initiatives are needed to improve the prevalence of preoperative nutrition screening. Poor muscle health is common in patients with malnutrition and further exacerbates negative health outcomes indicating that prevention, detection and treatment is of high importance in this population. Although a lack of consensus remains for who should receive preoperative nutritional therapy, evidence suggests a positive impact on muscle health. Additionally, postoperative nutritional support benefits surgical outcomes, with some patients requiring enteral and/or parenteral feeding routes and showing benefit from immunonutrition. The importance of nutrition extends beyond the time in hospital and should remain a priority post-discharge. The impact of individual or personalised nutrition based on select patient characteristics remains to be further investigated. Overall, the importance of perioperative nutrition is evident in the literature despite select ongoing areas of contention.

Circular Stapler Method for Avoiding Stricture of Cervical Esophagogastric Anastomosis

BACKGROUND

This study was performed to verify the superiority of a new "non-tensioning method" for avoiding stricture of the cervical esophagogastric anastomosis by circular stapling compared with the conventional method.

METHODS

In total, 395 consecutive patients who underwent McKeown esophagectomy with gastric conduit (GC) reconstruction were reviewed. A 4 cm-wide GC was created and pulled up at the cervical site through the retrosternal route. The esophagogastrostomy site of the GC was planned as far caudally as possible on the greater curvature side. In the conventional technique, the stapler was fired while pulling the GC to avoid tissue slack. In the non-tensioning technique, the stapler was fired through the natural thickness of the stomach wall. The length of the blind end was changed from 4 to 2 cm in the non-tensioning technique. Anastomotic leakage and stricture formation were compared between the two techniques, and adjustment was performed using propensity score matching.

RESULTS

The conventional group comprised 315 patients, and the non-tensioning group comprised 80 patients. Anastomotic leakage occurred in 22 (7%) and 2 (2.5%) patients, respectively (P = 0.134) [and in 9 (2.9%) and 2 (2.5%) patients, respectively, if leakage at the blind end was excluded]. Anastomotic stricture occurred in 92 (29.2%) and 3 (3.8%) patients, respectively (P < 0.001). The propensity score-matching analysis including 79 pairs of patients confirmed a lower stricture rate in the non-tensioning than conventional group (2.5% vs. 29.1%, P < 0.001).

CONCLUSIONS

The non-tensioning technique significantly reduced the incidence of anastomotic stricture compared with the conventional technique.

The effectiveness of telephone and Internet-based supportive care for patients with esophageal cancer on enhanced recovery after surgery in China: A randomized controlled trial

Objective

The aim of this study was to establish a nurse-led supportive care program based on telephone and Internet support and evaluate its efficacy in comparison with conventional care on enhanced recovery after surgery.

Methods

The study was designed as an open-label, randomized controlled trial to value the efficacy of a nurse-led supportive care program in comparison with conventional care. A convenience sampling method was employed to recruit patients with esophageal cancer in a tertiary Grade A cancer center in Beijing from November 2018 to January 2019. Patients were assigned randomly (1:1) to one of the two groups (intervention group vs control group) via a web randomization system. The control group received conventional care. Patients from the intervention group received conventional care and one-on-one phone calls from nurses following their discharge assessments and education about nutrition and symptoms. Nurses also set up a WeChat group, which they invited patients to join in before discharge for better communication during follow-up. Statistical testing, including nutritional status, quality of life, the helpfulness of the follow-up service, and the patients’ satisfaction with their care, was conducted 6 months after discharge to assess for differences between the two groups. The independent sample t, chi-squared, and Mann–Whitney tests were used to compare between the experiences of the intervention and control groups. The Spearman correlation analysis was used for the analysis of correlation of the nutritional index and quality of life.

Results

Finally, 168 patients were included in the study, with 86 patients in the intervention group and 82 in the control group. Significant differences between the intervention and control groups were found in the nutrition risk screening 2002 and simple diet self-assessment tool scores. The changes in blood albumin, prealbumin, and transferrin were also statistically significant. All (European Organization for Research and Treatment of Cancer Quality of Life Questionnaire) QLQ-C30 results of the intervention group were better than those of the control group. A significant positive correlation of the simple diet self-assessment tool (the higher, the better) and the scores for total health/quality of life were detected (r ​= ​0.214, P ​= ​0.005). A significant negative correlation of the nutrition risk screening 2002 (the lower, the better) and the scores of total health/quality of life was detected (r ​= ​−0.446, P ​= ​0.000). The patients’ scores on the helpfulness of the follow-up service and their satisfaction with it were both significantly higher in the intervention group than in the control group.

Conclusions

This study highlighted the important role of nurse-led supportive care based on telephone and Internet-based support for patients after enhanced recovery after surgery. The supportive care improved patients’ nutritional status, elevated their quality of life, and improved their satisfaction with the care provided to them.

Effect of Home Enteral Nutritional Support Compared With Normal Oral Diet in Postoperative Subjects With Upper Gastrointestinal Cancer Resection: A Meta-Analysis

Introduction

We performed a meta-analysis to evaluate the influence of a home enteral nutritional support compared with a normal oral diet in postoperative subjects with upper gastrointestinal cancer resection.

Methods

A systematic literature search up to December 2021 was done and 23 studies included 3,010 subjects with upper gastrointestinal cancer resection at the start of the study; 1,556 of them were given home enteral nutritional support and 1,454 were normal oral diet. We calculated the odds ratio (OR) and mean difference (MD) with 95% CIs to evaluate the influence of home enteral nutritional support compared with a normal oral diet in postoperative subjects with upper gastrointestinal cancer resection by the dichotomous or continuous methods with a random or fixed-influence model.

Results

Home enteral nutritional support had significantly higher quality of life (MD, 2.08; 95% CI, 1.50–2.67, p &lt; 0.001), better body weight change (MD, 1.87; 95% CI, 1.31–2.43, p &lt; 0.001), higher albumin (MD, 1.27; 95% CI, 0.72–1.82, p &lt; 0.001), and higher pre-albumin (MD, 30.79; 95% CI, 7.29–54.29, p = 0.01) compared to the normal oral diet in subjects with upper gastrointestinal cancer resection. However, home enteral nutritional support had no significant impact on the hemoglobin (MD, 4.64; 95% CI, −4.17 to 13.46, p = 0.30), and complications (OR, 1.03; 95% CI, 0.76–1.40, p = 0.83) compared to the normal oral diet in subjects with upper gastrointestinal cancer resection.

Conclusions

Home enteral nutritional support had a significantly higher quality of life, better body weight change, higher albumin, and higher pre-albumin, and had no significant impact on the hemoglobin and complications compared to the normal oral diet in subjects with upper gastrointestinal cancer resection. Further studies are required.

Survival Prediction Capabilities of Preoperative Inflammatory and Nutritional Status in Esophageal Squamous Cell Carcinoma Patients

BACKGROUND

Studies have revealed the impacts of various inflammatory and nutritional markers in patients with esophageal squamous cell carcinoma (ESCC). We evaluated the prognostic values of multiple inflammation- or nutrition-based markers, either alone or in combination with pStage, in ESCC patients.

METHODS

In total, 360 patients undergoing upfront surgery for ESCC were retrospectively reviewed. The prognostic capabilities of 7 inflammatory and 3 nutritional parameters were investigated. Furthermore, we devised new staging systems by adding these markers to pStage and examined the prognostic abilities of our new approach. Time-dependent receiver operating characteristic curves and the areas under the curve (AUCs) were estimated to compare prognostic capabilities among the parameters.

RESULTS

The AUCs for predicting overall survival (OS) of the prognostic nutritional index (PNI), CRP to albumin ration (CAR), lymphocyte to CRP ratio (LCR) and the Naples prognostic score (NPS) were similar to that of pStage. Notably, CAR and LCR showed high predictive capabilities for OS (AUCs; 0.627 and 0.634 for 3-year OS, respectively). New staging systems combining inflammatory or nutritional markers with pStage provided higher AUCs for predicting OS than pStage alone. In particular, NPpStage (NPS and pStage) (P = 0.03), PNpStage (PNI and pStage) (P = 0.03) and LCpStage (LCR and pStage) (P = 0.05) showed significantly higher accuracy for predicting OS than pStage alone.

CONCLUSIONS

Various inflammatory or nutritional markers, especially those derived from CRP, are useful for predicting survival outcomes of ESCC patients. The predictive capabilities of these indices were augmented when used in combination with pStage.

Case reports of new-onset eating disorders in older adult cancer survivors

BACKGROUND

It is unusual for a de novo eating disorder to emerge in late adulthood. Across a number of years, a number of patients were identified who experienced severe and unexpected weight loss post curative management of an upper abdominal cancer (i.e., cancer survivors). Each of the patients was readmitted to the tertiary surgical hospital due to complications of severe malnutrition. Each presentation was initially considered to have a major physical health problem (such as cancer recurrence). Each required extensive investigations and multidisciplinary team involvement and were later conceptualised as a new-onset (in later adulthood) eating disorder that emerged post curative cancer treatment. The team wished to better understand this group and/or characterise and/or inform the scientific community of this phenomena if not already well described.

LITERATURE REVIEW

The review identified that the re-emergence of pre-existing eating disorders at the time of cancer treatment was described; however, there was no identification of similar new-onset in later adulthood cases of eating disorders in cancer survivors in the medical literature.

REVIEW OF THE CASES

Once ethics and consent was obtained, then the clinical course of four complex individuals were reviewed, including the use of a multidisciplinary Delphi review process, to understand commonalities and then plot a common care pathway with potential intervention points.

CASE PRESENTATIONS

Common factors identified among the four patients included the lack of a physical health (organic) cause to the weight loss and ongoing weight loss despite intense multidisciplinary care. All had abnormal attitudes and behaviours relating to food, nutritional rehabilitation and/or recovery. None returned to a healthy weight and/or healthy eating despite extensive team input. The presentations were ultimately conceptualised as having severe disordered eating behaviours and in at least three cases met criteria for a formal eating disorder. The cohort had similar psychosocial characteristics including low socioeconomic status and complex family dynamics. None had prior formal psychiatric care. The outcomes were poor; one patient died, another required admission to a specialist eating disorder admission with a subsequent relapsing remitting course, and the remaining two had complicated chronic courses.

CONCLUSION

Similar cases may be underreported. If identified earlier, there may be a role for intervention to prevent high morbidity and mortality and to support clinical teams managing similar complex patients.

Early implementation of a perioperative nutrition support pathway for patients undergoing esophagectomy for esophageal cancer

Background

Unintentional weight loss and malnutrition are associated with poorer prognosis in patients with cancer. Risk of cancer‐associated malnutrition is highest among patients with esophageal cancer (EC) and has been repeatedly shown to be an independent risk factor for worse survival in these patients. Implementation of nutrition protocols may reduce postoperative weight loss and enhance recovery in these patients.

Methods

We retrospectively identified all patients who underwent Ivor Lewis esophagectomy for EC from January 2015 to August 2019 from a prospectively collected institutional database. Patients who underwent surgery after the implementation of this protocol (September 2017–August 2019) were compared with patients who underwent resection before protocol implementation (January 2015–July 2017). Patients undergoing surgery during the month of protocol initiation were excluded.

Results

Of the 404 patients included in our study, 217 were in the preprotocol group, and 187 were in the postprotocol group. Compared with the preprotocol group, there were significant reductions in length of hospital stay (p < 0.001), time to diet initiation (p < 0.001), time to feeding tube removal (p = 0.012), and postoperative weight loss (p = 0.002) in the postprotocol group. There was no significant difference in the incidence of postoperative complications, 30‐day readmission, or mortality rates between groups.

Conclusions

Results of the present study suggest a standardized perioperative nutrition protocol may prevent unintentional weight loss and improve postoperative outcomes in patients with EC undergoing resection.

Effectiveness of an early, quantified, modified oral feeding protocol on nutritional status and quality of life of patients after minimally invasive esophagectomy: A retrospective controlled study

OBJECTIVES

Previous studies confirmed the safety and feasibility of oral feeding on the first postoperative day (POD) for patients with minimally invasive esophagectomy (MIE). Nonetheless, some clinical concern can lead to delays in early oral feeding on POD 1. To our knowledge, few reports have focused on resolving these clinical concerns. The aims of this study were to evaluate the effects of an early, quantified, modified oral feeding protocol for patients after MIE and to explore its effect on nutritional status and quality of life (QoL).

METHODS

In this prospective controlled trail, 200 patients were selected as the intervention group (IG) from March 2020 to June 2021; 115 patients hospitalized from June 2019 to February 2020 were assigned to the control group (CG). For 2 wk during the postoperative period, IG participants received an early, quantified, modified oral feeding protocol. The recovery of dietary outcomes, nutritional status, and QoL were evaluated after the intervention.

RESULTS

There was no significant difference between the two groups in terms of demographic and clinical characteristics and baseline physical function. After the intervention, patients in the IG showed a more rapid growth in daily total oral caloric intake and the ratio of oral calorie intake to total calorie required by the body (K/R value) from POD 1 to POD 14, and less weight loss (1.5 ± 1 versus 2.1 ± 1.7 kg; P < 0.05), better serum prealbumin (193.0 ± 26.9 versus 139.3 ± 27.2 mg/L; P < 0.05) than the CG with statistical significance. By the second week of the intervention, IG patients reported higher global QoL and function scores and lower symptom scores than patients in the CG. The IG participants presented a shorter time to first flatus and bowel movement (P < 0.001), a shorter postoperative hospital length of stay, and higher activities of daily living scores (P < 0.05) the those in the CG.

CONCLUSIONS

The findings demonstrated that the early, quantified, modified oral feeding protocol can alleviate postoperative body weight loss, improve the patient's nutritional status, and have a positive effect on QoL and early recovery for patients undergoing MIE.

Timing of oral intake after esophagectomy: A narrative review of the literature and case report

Esophagectomy, a treatment modality for esophageal cancer, is associated with high rates of morbidity, the most common being anastomotic leaks and pulmonary complications. The current standard of care for nutrition support after esophagectomy includes a period of nothing by mouth with enteral nutrition support via jejunostomy tube owing to the concern of increasing the risk of anastomotic leak as a result of early postoperative oral intake. However, the optimal timing of oral diet initiation remains controversial. This narrative review presents a patient who incurred an anastomotic leak following esophagectomy after initiation of oral intake on postoperative day 5 and evaluates the current literature on the timing of oral diet initiation after esophagectomy. A systematic literature search was performed to assess current evidence evaluating early oral diet (EOD) initiation after esophagectomy. Over the past 5 years, 11 studies have evaluated the impact of EOD initiation after esophagectomy in comparison with a conventional feeding regimen, including a period of nothing by mouth with enteral or parenteral nutrition support. The available evidence suggests that EOD initiation does not increase rates of complications after esophagectomy. However, the evidence is limited by the lack of a standardized definition of what constitutes EOD initiation, patient selection bias, variations in nutrition support provided in the studies, and lack of statistical analyses evaluating the impact of potential confounding variables. Additional research with larger, high-quality randomized controlled trials is needed to determine the optimal timing of diet initiation after esophagectomy.

Impact of curative treatment on the physical fitness of patients with esophageal cancer: A systematic review and meta-analysis

BACKGROUND

Esophageal cancer and curative treatment have a significant impact on the physical fitness of patients. Knowledge about the course of physical fitness during neoadjuvant therapy and esophagectomy is helpful to determine the needs for interventions during and after curative treatment. This study aims to review the current evidence on the impact of curative treatment on the physical fitness of patients with esophageal cancer.

METHODS

A systematic literature search of PubMed, Embase, Cinahl and the Cochrane Library was conducted up to March 29, 2021. We included observational studies investigating the change of physical fitness (including exercise capacity, muscle strength, physical activity and activities of daily living) from pre-to post-neoadjuvant therapy and/or from pre-to post-esophagectomy. Quality of the studies was assessed and a meta-analysis was performed using standardized mean differences.

RESULTS

Twenty-seven articles were included. After neoadjuvant therapy, physical fitness decreased significantly. In the first three months after surgery, physical fitness was also significantly decreased compared to preoperative values. Subgroup analysis showed a restore in exercise capacity three months after surgery in patients who followed an exercise program. Six months after surgery, there was limited evidence that exercise capacity restored to preoperative values.

CONCLUSION

Curative treatment seems to result in a decrease of physical fitness in patients with esophageal cancer, up to three months postoperatively. Six months postoperatively, results were conflicting. In patients who followed a pre- or postoperative exercise program, the postoperative impact of curative treatment seems to be less.

Oral Nutritional Supplements and Enteral Nutrition in Patients with Gastrointestinal Surgery

Nowadays, patients undergoing gastrointestinal surgery are following perioperative treatment in enhanced recovery after surgery (ERAS) protocols. Although oral feeding is supposed not to be stopped perioperatively with respect to ERAS, malnourished patients and inadequate calorie intake are common. Malnutrition, even in overweight or obese patients, is often underestimated. Patients at metabolic risk have to be identified early to confirm the indication for nutritional therapy. The monitoring of nutritional status postoperatively has to be considered in the hospital and after discharge, especially after surgery in the upper gastrointestinal tract, as normal oral food intake is decreased for several months. The article gives an overview of the current concepts of perioperative enteral nutrition in patients undergoing gastrointestinal surgery.

ESPEN practical guideline: Clinical nutrition in surgery

Early oral feeding is the preferred mode of nutrition for surgical patients. Avoidance of any nutritional therapy bears the risk of underfeeding during the postoperative course after major surgery. Considering that malnutrition and underfeeding are risk factors for postoperative complications, early enteral feeding is especially relevant for any surgical patient at nutritional risk, especially for those undergoing upper gastrointestinal surgery. The focus of this guideline is to cover both nutritional aspects of the Enhanced Recovery After Surgery (ERAS) concept and the special nutritional needs of patients undergoing major surgery, e.g. for cancer, and of those developing severe complications despite best perioperative care. From a metabolic and nutritional point of view, the key aspects of perioperative care include the integration of nutrition into the overall management of the patient, avoidance of long periods of preoperative fasting, re-establishment of oral feeding as early as possible after surgery, the start of nutritional therapy immediately if a nutritional risk becomes apparent, metabolic control e.g. of blood glucose, reduction of factors which exacerbate stress-related catabolism or impaired gastrointestinal function, minimized time on paralytic agents for ventilator management in the postoperative period, and early mobilization to facilitate protein synthesis and muscle function.

Safety analysis of early oral feeding after esophagectomy in patients complicated with diabetes

Objective

To evaluate the safety of early oral feeding in patients with type II diabetes after radical resection of esophageal carcinoma.

Methods

The clinical data of 121 patients with type II diabetes who underwent radical resection of esophageal carcinoma in the department of cardiothoracic surgery of Jinling Hospital from January 2016 to December 2018 were retrospectively analyzed. According to the median time (7 days) of the first oral feeding after surgery, the patients were divided into early oral feeding group (EOF, feeding within 7 days after surgery, 67 cases) and late oral feeding group (LOF, feeding after 7 days, 54 cases). Postoperative blood glucose level, incidence of complications, nutritional and immune indexes, inflammatory indexes, normalized T12-SMA (the postoperative/preoperative ratio of vertical spinal muscle cross-sectional area at the 12th thoracic vertebra level) and QLQ-C30 (Quality Of Life Questionnaire) scores were recorded and compared in the two groups.

Results

There was no statistical difference in preoperative nutritional index and postoperative complication rates between the EOF and LOF group (p > 0.05). The postoperative nutritional index (ALB, PA, TRF, Hb) and immune index (IgA, IgG, IgM) of the EOF group were higher than those of the LOF group (p < 0.05), and the inflammatory indicators (CRP, IL-6) of the EOF group were significantly lower than those of the LOF group (p < 0.05). Moreover, postoperative T12-SMA variation and QLQ-C30 scores of the EOF group were higher than those in LOF group (p < 0.05).

Conclusions

Early oral feeding is safe and feasible for patients with type II diabetes after radical resection of esophageal cancer, and it can improve short-term nutritional status and postoperative life quality of the patients.

Postoperative Changes in Nutritional and Functional Status of Gastroesophageal Cancer 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.

Association between low-fat enteral nutrition after esophagectomy and a lower incidence of chyle leakage: A call for more and better evidence

Objective

Reliable methods to prevent chyle leakage after esophagectomy are needed. This retrospective study was performed to evaluate the correlation between low-fat nutrition and the incidence of chyle leakage after esophagectomy.

Methods

This multicenter retrospective case–control study involved patients who underwent Ivor Lewis esophagectomy from December 2012 to August 2017. Tube feeding was started on postoperative day 1 with a normal fat-containing formula (control group, 203 patients) or low fat-containing formula (241 patients).

Results

The patients in the control group and low-fat group had a similar incidence of chyle leakage (7 [3.4%] vs. 19 [9.4%], respectively) and anastomotic leakage (4 [2.0%] vs. 11 [5.4%], respectively). The multivariate logistic regression indicated that high-volume surgeon experience (performance of ≥100 esophagectomies per year) was correlated with a lower incidence of chyle leakage (odds ratio, 0.280; 95% confidence interval, 0.110–0.712), whereas low-fat nutrition was correlated with an increased risk of anastomotic leakage (odds ratio, 5.995; 95% confidence interval, 1.201–29.925).

Conclusion

Prophylactic low-fat enteral nutrition following esophagectomy might not decrease the risk of chyle leakage. More and better evidence is needed.

[Perioperative nutritional supplementation-what is really evidence based?]

For patients undergoing major surgery, perioperative management according to an early recovery after surgery (ERAS) protocol focusing on early oral food intake is the strategy of choice. So-called perioperative nutritional (artificial) support now seems to be very traditional and outdated. Nevertheless, even in an overweight and obese society the prevalence of combined malnutrition and/or sarcopenia should not be underestimated. This results in the necessity for identification of patients at metabolic risk and the indications for nutritional therapy. This article provides a review of the current concepts of perioperative nutritional supplementation and discusses the available evidence and guideline recommendations.

Severe weight loss after minimally invasive oesophagectomy is associated with poor survival in patients with oesophageal cancer at 5 years

BACKGROUND

Patients often experience severe weight loss after oesophagectomy. Enteral nutrition via a feeding jejunostomy tube (FT) is commonly practised. This study aimed to assess the effect of severe weight loss postoperatively and enteral nutrition via an FT on long-term prognosis after oesophagectomy.

METHODS

This study analysed 317 patients who underwent minimally invasive oesophagectomy at Kobe University Hospital and Hyogo Cancer Center from 2010 to 2015. The patients' body weight was evaluated at 3 months postoperatively. They were organised into the severe weight loss (n = 65) and moderate weight loss (n = 252) groups. Furthermore, they were categorised into the FT group (184 patients who had an FT placed during oesophagectomy) and no-FT group (133 patients without FT). Patients (119 per group) matched for the FT and no-FT groups were identified via propensity score matching.

RESULTS

The 5-year overall survival (OS) rate in the severe weight loss group was significantly lower (p = 0.024). In the multivariate analysis, tumour invasion depth (pT3-4), preoperative therapy and severe weight loss had a worse OS (hazard ratio = 1.89; 95% confidence interval = 1.12-3.17, hazard ratio = 2.11; 95% confidence interval = 1.25-3.54, hazard ratio = 1.82; 95% confidence interval = 1.02-3.524, respectively). No significant differences in the number of severe weight loss patients and OS were found between the FT and no-FT groups.

CONCLUSION

Severe weight loss is significantly associated with poor OS. In addition, enteral nutrition via an FT did not improve the severe weight loss and OS.

Home enteral nutrition and oral nutritional supplements in postoperative patients with upper gastrointestinal malignancy: A systematic review and meta-analysis

BACKGROUND

The safety and potential benefits of home enteral route nutrition (HERN), referring specifically to home enteral nutrition (HEN) and oral nutritional supplements (ONS) in this article, after upper gastrointestinal (GI) resection are inconsistent.

OBJECTIVE

To evaluate the impact of HERN on nutritional status, complications, and quality of life (QOL) after upper GI resection.

METHODS

This systematic review was conducted in accordance with the PRISMA statement. Nine databases were searched from inception to October 2019. Randomized controlled trials (RCTs) comparing the impact of HERN after upper gastrointestinal resection were included. Relative risk/weighted mean difference/standardized mean difference (RR/WMD/SMD) and corresponding 95% confidence intervals (95% CI) were calculated using fixed- or random-effects models.

RESULTS

Overall, 15 RCTs involving 1059 patients were included. Compared with normal oral diet, HERN significantly prevented weight loss (-3.95 vs -5.82 kg; SMD: 1.98 kg; 95% CI: 1.24-2.73); improved added-level of albumin (3.48 vs 2.41 g/L; SMD: 1.36 g/L; 95% CI: 0.81-1.91), hemoglobin (6.54 vs -1.29 g/L; WMD: 7.45 g/L; 95% CI: 5.05-9.86), pre-albumin (37.59 vs 7.35 mg/L; WMD: 21.6 mg/L; 95% CI: 5.96-37.24), and transferrin (63.08 vs 50.45 mg/L; WMD: 16.44 mg/L; 95% CI: 13.51-19.38); and reduced the incidence of malnutrition or latent malnutrition (RR = 0.54; P < 0.01). Subgroup analysis based on the approach of HERN showed that weight loss in the HEN subgroup was significantly lower than that of the control group (WMD = 2.69, P < 0.01), while there was no significant difference between the ONS subgroup and the control group (P = 0.1). The same results were found in albumin. Physical function (WMD: 5.29; 95% CI: 1.86-8.73) and fatigue (WMD: -8.59; 95% CI: -12.61, -4.58) dimensions in QOL were significantly better in the HERN group. No significant differences in gastrointestinal and tube-related complications.

CONCLUSION

HERN improved nutritional status and some dimensions of QOL in upper GI malignancy patients after surgery, without increasing complications. Subgroup analysis showed that HEN experienced more benefits than ONS.

Gastrointestinal side effects of upper gastrointestinal cancer surgery

In this chapter, we describe the gastrointestinal side effects of oesophagectomy, gastrectomy and pancreaticoduodenectomy for cancer, with a focus on long-term functional impairments and their management. Improvements in upper gastrointestinal cancer surgery have led to a growing group of long-term survivors. The invasive nature of these surgeries profoundly alters the upper gastrointestinal anatomy, with lasting implications for long-term function, and how these impairments may be treated. Successfully maintaining a high quality of survivorship requires multidisciplinary approach, with survivorship care plans focused on function as much as the detection of recurrence.

Home enteral nutrition after esophagectomy for esophageal cancer: A systematic review and meta-analysis

BACKGROUND

Not only has the placement rate of enteral feeding tubes during operations for esophageal cancer increased, but also has number of patients who choose to continue enteral feeding at home instead of removing the feeding tube at discharge. The impacts of home enteral nutrition (HEN) after esophagectomy in esophageal cancer patients are analyzed.

METHODS

A systematic review was conducted in accordance with PRISMA and Cochrane guidelines. English and Chinese databases, including PubMed, Embase, Web of Science, The Cochrane Library, Scopus, CBM, CNKI, and Wan Fang were searched from inception to December 7, 2019. Randomized controlled trials evaluating the short-term outcomes of HEN following esophagectomy in cancer patients were included. The risk of bias of the included studies was appraised according to the Cochrane risk of bias tool. The summary of relative risk/weighted mean difference (WMD) estimates and corresponding 95% confidence interval (95% CI) were calculated using fixed- and random-effects models.

RESULTS

Nine randomized controlled trials involving 757 patients were included in the meta-analysis. Compared with oral diet, HEN was associated with significantly increased body weight (WMD 3 kg, 95% CI 2.36-3.63, P < .001), body mass index (WMD 0.97 kg/m, 95% CI 0.74-1.21, P < .001), albumin (WMD 3.43 g/L, 95% CI 2.35-4.52, P < .001), hemoglobin (WMD 7.23 g/L, 95% CI 5.87-8.59, P < .001), and total protein (WMD 5.13 g/L, 95% CI 3.7-6.56, P < .001). No significant differences were observed in prealbumin and gastrointestinal adverse reactions. Physical (WMD 8.82, 95% CI 6.69-10.95, P < .001) and role function (WMD 12.23, 95% CI 2.72-21.74, P = .01) were also significantly better in the HEN group. The nausea/vomiting (WMD -5.43, 95% CI -8.29 to -2.57, P = .002) and fatigue symptoms (WMD -11.76, 95% CI -16.21 to -7.32, P < .001) were significantly reduced. Appetite loss (WMD -8.48, 95% CI -14.27 to -4.88, P = .001), diarrhea (WMD -3.9, 95% CI -7.37 to -0.43, P = .03), and sleep disturbance (WMD -7.64, 95% CI -12.79 to -2.5, P = .004) in the HEN group were also significantly less than the control group.

CONCLUSIONS

HEN improved nutrition status, physical and role function, and reduced nausea/vomiting, fatigue, appetite loss, diarrhea, and sleep disturbance compared with an oral diet in esophageal cancer patients postsurgery. HEN did not increase adverse reactions.

Needle Catheter Jejunostomy in Patients Undergoing Surgery for Upper Gastrointestinal and Pancreato-Biliary Cancer-Impact on Nutritional and Clinical Outcome in the Early and Late Postoperative Period

The metabolic risk for patients undergoing abdominal cancer resection increases in the perioperative period and malnutrition may be observed. In order to prevent further weight loss, the guidelines recommend for high-risk patients the placement of a needle catheter jejunostomy (NCJ) for supplementing enteral feeding in the early and late postoperative period. Our aim was to evaluate the safety of NCJ placement and its potential benefits regarding the nutritional status in the postoperative course. We retrospectively analyzed patients undergoing surgery for upper gastrointestinal cancer, such as esophageal, gastric, and pancreato-biliary cancer, and NCJ placement during the operation. The nutritional parameters body mass index (BMI), perioperative weight loss, phase angle measured by bioelectrical impedance analysis (BIA) and the clinical outcome were assessed perioperatively and during follow-up visits 1 to 3 months and 4 to 6 months after surgery. In 102 patients a NCJ was placed between January 2006 and December 2016. Follow-up visits 1 to 3 months and 4 to 6 months after surgery were performed in 90 patients and 88 patients, respectively. No severe complications were seen after the NCJ placement. The supplementing enteral nutrition via NCJ did not improve the nutritional status of the patients postoperatively. There was a significant postoperative decline of weight and phase angle, especially in the first to third month after surgery, which could be stabilized until 4-6 months after surgery. Placement of NCJ is safe. In patients with upper gastrointestinal and pancreato-biliary cancer, supplementing enteral nutrition during the postoperative course and continued after discharge may attenuate unavoidable weight loss and a reduction of body cell mass within the first six months.

Development and Feasibility of a Mobile Health-Supported Comprehensive Intervention Model (CIMmH) for Improving the Quality of Life of Patients With Esophageal Cancer After Esophagectomy: Prospective, Single-Arm, Nonrandomized Pilot Study

BACKGROUND

Patients with esophageal cancer often experience clinically relevant deterioration of quality of life (QOL) after esophagectomy owing to malnutrition, lack of physical exercise, and psychological symptoms.

OBJECTIVE

This study aimed to evaluate the feasibility, safety, and efficacy of a comprehensive intervention model using a mobile health system (CIMmH) in patients with esophageal cancer after esophagectomy.

METHODS

Twenty patients with esophageal cancer undergoing the modified McKeown surgical procedure were invited to join the CIMmH program with both online and offline components for 12 weeks. The participants were assessed before surgery and again at 1 and 3 months after esophagectomy. QOL, depressive symptoms, anxiety, stress, nutrition, and physical fitness were measured.

RESULTS

Of the 20 patients, 16 (80%) completed the program. One month after esophagectomy, patients showed significant deterioration in overall QOL (P=.02), eating (P=.005), reflux (P=.04), and trouble with talking (P<.001). At the 3-month follow-up, except for pain (P=.02), difficulty with eating (P=.03), dry mouth (P=.04), and trouble with talking (P=.003), all other QOL dimensions returned to the preoperative level. There were significant reductions in weight (P<.001) and BMI (P=.02) throughout the study, and no significant changes were observed for physical fitness measured by change in the 6-minute walk distance between baseline and the 1-month follow-up (P=.22) or between baseline and the 3-month follow-up (P=.52). Depressive symptoms significantly increased 1 month after surgery (P<.001), while other psychological measures did not show relevant changes. Although there were declines in many measures 1 month after surgery, these were much improved at the 3-month follow-up, and the recovery was more profound and faster than with traditional rehabilitation programs.

CONCLUSIONS

The CIMmH was feasible and safe and demonstrated encouraging efficacy testing with a control group for enhancing recovery after surgery among patients with esophageal cancer in China.

A radical change: A qualitative study of patients' experiences of eating and daily living through the first year after oesophageal resection

PURPOSE

The purpose of this study is to explore the lived experiences of patients in terms of eating and consequences in everyday life in the first year after oesophageal cancer surgery.

METHODS

Thirteen patients participated in qualitative interviews one year after surgery for oesophageal cancer. Descriptions capturing the meaning of the lived experiences of patients were then derived from subsequent analysis and interpretation of the interviews. A phenomenological hermeneutical approach comprised the epistemological stance, and theoretical perspectives were drawn from Schutz' theory of everyday life.

RESULTS

Patient descriptions of their experiences with food, eating and everyday life in the first year after oesophageal cancer surgery fell into four themes: Adjusting to a different anatomy - food and eating as a dominant and difficult activity; changed body - food and eating as an underlying shadow; feeling different - social consequences of changed eating; a nutritional jungle - guidance and support in an uncertain time.

CONCLUSION

The physical and social consequences of oesophageal cancer resection upend everyday structures, requiring patients to adopt a new, conscious and reflexive approach to food and eating as a social activity. Continuous support from healthcare professionals and patient-to-patient interaction can help redefine everyday life.

Esophageal cancer patients of heavier weight have more nutritional risk of inadequate calorie intake immediately after esophagectomy: a retrospective study

BACKGROUND

Perioperative malnutrition is common in patients undergoing esophagectomy, and nutritional support is critical for postoperative recovery in these patients. But few studies reported which characteristics of these patients were associated with post-esophagectomy inadequate calorie intake. This study aimed to explore which patients were more likely to have inadequate calories immediately after esophagectomy and the impact on clinical outcomes.

METHODS

From January 2018 to June 2019, patients undergoing esophagectomy were retrospectively divided into the "adequate calorie group" and the "inadequate calorie group" according to whether they met daily calorie requirements in a week after esophagectomy. Caloric requirements met rate and clinical outcomes were compared between patients with and without complications, and with weight > 70 kg or ≤ 70 kg.

RESULTS

Patients in the inadequate calorie group (n = 104) had significantly higher weight (p < 0.001), lean body mass (p = 0.028), and BMI (p = 0.001) than the adequate calorie group (n = 46). Weight loss after esophagectomy was reduced (p = 0.043) in the adequate calorie group. Patients with complications had lower rate of adequate calorie intake (72.8% vs. 63.8%). The caloric requirements met rate in patients with weigh ≤ 70 kg was significantly higher than those weight > 70 kg (80.2% vs. 43.2%, p < 0.001).

CONCLUSION

The weights of patients having inadequate calories in a week after esophagectomy were significantly heavier than those having adequate calories. Heavier patients after esophagectomy should attract more attention to their nutrition support.

Prognostic Implication of Postoperative Weight Loss After Esophagectomy for Esophageal Squamous Cell Cancer

BACKGROUND

Preoperative weight loss in esophageal cancer is reported to be associated with a poor prognosis. However, the impact of postoperative weight loss on the prognosis of patients with esophageal cancer remains unclear.

METHODS

This study included 186 patients with esophageal squamous cell carcinoma who underwent surgery between January 2012 and January 2015. The relationship between weight loss 6 months after esophagectomy as well as the clinical factors and prognosis of patients was investigated.

RESULTS

The mean weight loss rate for all the patients was 9.3% at 3 months, 10.8% at 6 months, 11.1% at 12 months, and 11.4% at 24 months after surgery. The patients with severe weight loss 6 months after surgery (≥ 12%) exhibited lower serum albumin levels and a lower prognostic nutrition index 6 months after esophagectomy than the patients with moderate weight loss (< 12%; p = 0.011 and 0.009, respectively). Although overall survival did not differ significantly between the two groups, for all the patients, severe weight loss was significantly associated with shortened overall survival for the cStages 3 and 4 patients (3-year overall survival rate, 76.6% in the moderate group vs 54.5% in the severe group; p = 0.042). The multivariate analyses identified only severe weight loss as an independent factor associated with worse overall survival for the cStages 3 and 4 patients (p = 0.034).

CONCLUSION

This study showed that postoperative weight loss negatively affected the prognosis for patients with advanced esophageal cancer, indicating the necessity of administering nutritional interventions to these patients to prevent postoperative weight loss.
