Optimal timing and route of nutritional support after esophagectomy: A review of the literature

Comparison of the Efficacy of Indwelling Gastric Tubes in Preoperative and Postoperative Patients With Oral and Maxillofacial Malignancies

PURPOSE

To explore the optimal plan for the timing of indwelling gastric tube placement in oral and maxillofacial malignant tumor patients.

DESIGN

A prospective randomized controlled trial.

METHODS

80 patients with oral and maxillofacial tumor were selected, and 40 patients were Pre-operative group. The remaining 40 patients were the control group, called Postoperative group. The body weight and hospital stay of the two groups were observed before and after surgery. Blood samples were taken before surgery and 1, 3 and 7 days after surgery to detect hemoglobin and plasma albumin.

FINDINGS

The number of postoperative hospitalization days in the pre-operative group was significantly lower than that in the post-operative group; postoperative hemoglobin and plasma albumins were lower in both groups compared with the preoperative level.

CONCLUSIONS

Preoperative nasogastric tube ensured early postoperative administration of gastrointestinal nutrition, promoted postoperative plasma albumin recovery, and shortened the days of hospitalization.

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.

Effect of Early Versus Late Oral Feeding on Postoperative Complications and Recovery Outcomes for Patients with Esophageal Cancer: A Systematic Evaluation and Meta-Analysis

BACKGROUND

This study aimed to systematically evaluate the effect of early oral feeding (EOF) versus late oral feeding (LOF) on postoperative complications and rehabilitation outcomes for patients with esophageal cancer.

METHODS

This study searched relevant literature published up to March 2023 by computer retrieval of PubMed, Embase, The Cochrane Library, and Web of Science. A meta-analysis was performed using Review Manager 5.4 software to compare the effects of EOF and LOF on postoperative complications and recovery outcomes of patients with esophageal cancer.

RESULTS

The study included 14 articles, including 9 retrospective studies, 4 randomized controlled trials (RCTs), and 1 prospective study. The 2555 patients included in the study comprised 1321 patients who received EOF and 1234 patients who received LOF. The results of the meta-analysis showed that compared with the LOF group, the EOF group has a shorter time to the first flatus postoperatively (mean difference [MD],  -  1.12; 95% confidence interval [CI], (-  1.25 to -  1.00; P < 0.00001), a shorter time to the first defecation postoperatively (MD, -  1.31; 95% CI, -  1.67 to -   0.95;, P < 0.00001], and a shorter hospital stay postoperatively (MD, -  2.87; 95% CI, -  3.84 to -  1.90; P < 0.00001). The two groups did not differ significantly statistically in terms of postoperative anastomotic leakage rate (P = 0.10), postoperative chyle leakage rate (P = 0.10), or postoperative pneumonia rate (P = 0.15).

CONCLUSION

Early oral feeding after esophageal cancer surgery can shorten the time to the first flatus and the first defecation postoperatively, shorten the hospital stay, and promote the recovery of patients. Moreover, it has no significant effect on the incidence of postoperative complications.

Impact of Enhanced Recovery Protocols on Short-Term Outcomes in Esophagectomy: A Retrospective Cohort Study from Cancer Research Institute, Uttarakhand, India

OBJECTIVE

Surgery for esophageal cancer is associated with high mortality and morbidity, especially in low and middle-income countries. The recent enhanced recovery after surgery guidelines for esophagectomy (2018) which attempt to reduce complications and length of stay (LOS) have rarely been validated in these settings. This study aimed to analyse the effect of this protocol on short-term outcomes in our subset of patients.

METHODS

A retrospective review was conducted to investigate the outcomes of enhanced recovery protocol (ERP) compared to standard pre-protocol care (PP) in patients who underwent esophagectomy for cancer (31 in ERP vs 61 in PP group) at Cancer Research Institute, Uttarakhand, India. The main outcomes measured were 30-day mortality, morbidity and LOS. Risk assessment was stratified as per Physiological and Operative Severity Score for the Enumeration of Mortality and Morbidity (POSSUM) systems while complications were classified as per the Clavien-Dindo scale.

RESULTS

Preoperative clinical characteristics were similar between groups. Though the predicted POSSUM mortality and morbidity were significantly higher in the ERP group (p = 0.007), 30-day morbidity (19.35% vs 42.62%, p = 0.027) as well as median LOS (12 vs 15 days, p < 0.001) was significantly lower in ERP group. The PP group reported 4 deaths within 30 days as compared to none in the ERP group (p = 0.296). Furthermore, the ERP group reported lower occurrence of pulmonary complications (6.4%vs24.6%,p = 0.046), hemodynamic instability (0%vs14.75%,p = 0.026) as well as need for prolonged postoperative ventilation (> 24 h; 0% vs 11.48%, p = 0.004). Both minor and major complications as assessed by the Clavien-Dindo scale were lower in the group ERP though these differences were not statistically significant (0.059).

CONCLUSIONS

Implementation of ERP improved short-term outcomes; hence can be strongly recommended in patients undergoing esophagectomy.

Epidemiology of Postoperative Complications After Esophagectomy: Implications for Management

BACKGROUND

Despite advances in operative techniques and postoperative care, esophagectomy remains a morbid operation. Leveraging complication epidemiology and the correlation of these complications may improve rescue and refine early recovery pathways.

METHODS

This study retrospectively reviewed all esophagectomies performed at a tertiary academic center from 2014 to 2021 and quantified the timing of the most common complications. Daily incidence values for index complications were calculated, and a covariance matrix was created to examine the correlation of the complications with each other. Study investigators performed a Cox proportional hazards analysis to clarify the association between early diagnosis of postoperative atrial fibrillation and pneumonia with subsequent anastomotic leak.

RESULTS

The study analyzed 621 esophagectomies, with 580 (93.4%) cervical anastomoses and 474 (76%) patients experiencing complications. A total of 159 (25.6%) patients had postoperative atrial fibrillation, and 155 (25.0%) had an anastomotic leak. The median (interquartile range [IQR]) postoperative day of these complications was day 2 (IQR, days 2-3) and day 8 (IQR, days 7-11), respectively. Our covariance matrix found significant associations in the variance of the most common postoperative complications, including pneumonia, atrial fibrillation, anastomotic leak, and readmissions. Early postoperative atrial fibrillation (hazard ratio, 8.1; 95% CI, 5.65-11.65) and postoperative pneumonia (hazard ratio, 3.8; 95% CI, 1.98-7.38) were associated with anastomotic leak.

CONCLUSIONS

Maintaining a high index of suspicion for early postoperative complications is crucial for rescuing patients after esophagectomy. Early postoperative pneumonia and atrial fibrillation may be sentinel complications for an anastomotic leak, and their occurrence may be used to prompt further clinical investigation. Early recovery protocols should consider the development of early complications into postoperative feeding and imaging algorithms.

Examining the impact of early enteral nutritional support on postoperative recovery in patients undergoing surgical treatment for gastrointestinal neoplasms

BACKGROUND

Patients with gastrointestinal tumors often suffer from poor nutritional status during treatment. Surgery is the main treatment for these patients, but the long postoperative recovery period is often accompanied by digestive and absorption dysfunction, leading to further deterioration of the nutritional status. Early enteral nutrition support is hypothesized to be helpful in improving this situation, but the exact effects have yet to be studied in depth.

AIM

To observe the effect of early enteral nutritional support on postoperative recovery in patients with surgically treated gastrointestinal tract tumors, with the expectation that by improving the nutritional status of patients, the recovery process would be accelerated and the incidence of complications would be reduced, thus improving the quality of life.

METHODS

A retrospective analysis of 121 patients with gastrointestinal tract tumors treated in our hospital from January 2020 to January 2023 was performed. Fifty-three of these patients received complete parenteral nutrition support as the control group for this study. The other 68 patients received early enteral nutritional support as the observation group of this study. The clinical indicators comparing the two groups included time to fever, time to recovery of postoperative bowel function, time to postoperative exhaustion, and length of hospital stay. The changes in immune function and nutritional indexes in the two groups were compared. Furthermore, we utilized the SF-36 scale to compare the changes in the quality of life between the two groups of patients. Finally, the occurrence of postoperative complications between the two patient groups was also compared.

RESULTS

The postoperative fever time, postoperative bowel function recovery time, postoperative exhaustion time, and hospitalization time were all higher in the control group than in the observation group (P < 0.05). The levels of CD3+, CD4+, immunoglobulin (Ig) A, IgM, and IgG in the observation group were significantly higher than those in the control group at 1 d and 7 d postoperatively, while CD8+ was lower than in the control group (P < 0.05). Total protein, albumin, prealbumin, and transferrin levels were significantly higher in the observation group than in the control group at 7 d postoperatively (P < 0.05). The SF-36 scores of patients in the observation group were significantly higher than those in the control group (P < 0.0001). The overall incidence of adverse reactions after the intervention was significantly lower in the control group than in the observation group (P = 0.021).

CONCLUSION

We found that patients with gastrointestinal tumors are nutritionally vulnerable, and early enteral nutrition support programs can improve the nutritional status of patients and speed up postoperative recovery. This program can not only improve the immune function of the patient and protect the intestinal function, but it can also help to improve the quality of life of the patient. However, this program will increase the incidence of complications in patients. Caution should be taken when adopting early enteral nutrition support measures for patients with gastric cancer. The patient's condition and physical condition should be comprehensively evaluated and closely monitored to prevent possible complications.

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.

Clinical effect of home enteral tube feeding supplementation on nutritional status after esophagectomy with retrosternal gastric tube reconstruction

Body weight loss and poor nutritional status are frequently observed after esophageal cancer surgery. The aim of this study was to pilot an investigation on the impact of home enteral tube feeding supplementation (HES) for up to 3 months after esophageal cancer surgery. We retrospectively reviewed consecutive 67 esophageal cancer patients who underwent esophagectomy with gastric tube reconstruction. We started HES from April 2017. The patients were divided into 2 groups. Among 67 patients, 40 patients underwent HES between April 2017 and November 2020 (HES group). Other 27 patients who underwent esophagectomy between January 2012 and March 2017 were not administered HES (C group). Thereafter, multiple factors concerning patient nutritional status at long-term follow-up were evaluated. The baseline characteristics were balanced between the two groups. There were no significant differences in nutritional status scores before esophagectomy. The percentage weight loss was less in the HES group compared with the C group both at 3 months and 1 year after surgery: 7.3% (-7.6 to 15.2), 7.7% (-4 to 13.9) in the HES group and 10.6% (-3.6 to 29.1), 10.8% (-5.8 to 20.0) in C group (P < 0.05, P < 0.05). In the patients with anastomotic stenosis, the percentage weight loss was less in the HES group compared with the C group: 7.2% (2.0-14.9) and 14.6% (6.2-29.1), P < 0.05. HES may improve early weight loss in postesophagectomy patients.

Effect of dietary consumption on the survival of esophageal squamous cell carcinoma: a prospective cohort study

BACKGROUND/OBJECTIVES

This prospective cohort study was to assess the association of pre-diagnostic dietary intake and dietary pattern with the survival of esophageal squamous cell carcinoma (ESCC) patients.

SUBJECTS/METHODS

855 patients were recruited and successfully followed. Information on diet over past five years before diagnosis was collected using a food frequency questionnaire, and dietary patterns were extracted using principal component analysis. Hazard ratio (HR) with 95% confidence interval (95% CI) was calculated using the Cox proportional hazard model.

RESULTS

164 (19.18%) ESCC patients survived during the follow-up. Every 25-g increment intake of pickled vegetables was associated with a 6.0% (HR: 1.060, 95% CI: 1.003-1.121) increased risk of death after adjustment for covariates. When comparing the highest with lowest tertiles of energy-adjusted intake, pickled vegetables intake was associated with a 21.9% elevated risk of death (HR: 1.219, 95% CI: 1.014-1.465), while fish and shrimp intake was associated with a 19.4% (HR: 0.816, 95% CI: 0.675-0.986) reduced risk of death. Three dietary patterns were defined and labeled as patterns I, II, and III. Every 10-score increment of dietary pattern II, characterized with a higher loading of preserved vegetables, pickled vegetables, and salted meat, was associated with a 1.7% (HR: 1.017, 95% CI: 1.003-1.032) increased risk of death.

CONCLUSIONS

A diet characterized with higher loading of preserved vegetables, pickled vegetables, and salted meat, was negatively associated with death risk among ESCC patients. Prospective studies concerning the role of post-diagnosis dietary intake in ESCC prognosis are needed.

Hospital Variation in Feeding Jejunostomy Policy for Minimally Invasive Esophagectomy: A Nationwide Cohort Study

The purpose of this study was to investigate hospital variation in the placement, surgical techniques, and safety of feeding jejunostomies (FJ) during minimally invasive esophagectomy (MIE) in the Netherlands. This nationwide cohort study analyzed patients registered in the Dutch Upper Gastrointestinal Cancer Audit (DUCA) that underwent MIE for cancer. Hospital variation in FJ placement rates were investigated using case-mix corrected funnel plots. Short-term outcomes were compared between patients with and without FJ using multilevel multivariable logistic regression analysis. The incidence of FJ-related complications was described and compared between hospitals performing routine and non-routine placement (≥90%−<90% of patients). Between 2018−2020, an FJ was placed in 1481/1811 (81.8%) patients. Rates ranged from 11−100% among hospitals. More patients were discharged within 10 days (median hospital stay) without FJ compared to patients with FJ (64.5% vs. 50.4%; OR: 0.62, 95% CI: 0.42−0.90). FJ-related complications occurred in 45 (3%) patients, of whom 23 (1.6%) experienced severe complications (≥Clavien−Dindo IIIa). The FJ-related complication rate was 13.7% in hospitals not routinely placing FJs vs. 1.7% in hospitals performing routine FJ placement (p < 0.001). Significant hospital variation in the use of FJs after MIE exists in the Netherlands. No effect of FJs on complications was observed. FJs can be placed safely, with lower FJ-related complication rates, in centers performing routine placement.

Cessation of Routine Jejunostomy Tube Placement at Time of Minimally Invasive Ivor Lewis Esophagectomy and Impact on Body Mass Index

Jejunostomy tubes are frequently placed at time of esophagectomy. The purpose of this study is to evaluate cessation of routine j-tube placement on postoperative body mass index (BMI), return to the emergency room, and time until adjuvant therapy. We performed a retrospective review of an institutional database for consecutive patients undergoing minimally invasive Ivor Lewis Esophagectomy from 2014-2021 (after January 2019, routine j-tube placement was abandoned). Data was analyzed using Pearson's Chi-squared tests and Student's t test with 2-sided significance level of P < 0.05. In total,179 patients were included, 95 underwent j-tube placement and 84 did not. Cohorts had comparable baseline BMI's (no j-tube: 30.48 vs j-tube: 28.64, P = 0.06) and anastomotic leak rates (2.4% vs 4.2%, P = 0.5). Patients with no jejunostomy tubes were more likely to receive total parenteral nutrition (14.3% vs 5.3%, P < 0.05), but were no more likely to require total parenteral nutrition at discharge and had comparable durations of TPN requirement (7 days vs 12 days, P = 0.53). There was no difference in mean BMI reduction at 2 weeks (2.54 vs 2.09, P = 0.49) and 3-6 months postoperatively (6.11 vs 4.45 P = 0.15). There was no difference in return to the emergency room (8.3% vs 8.4%, P = 0.98) or readmissions (13.1% vs 11.6%, P = 0.76). There was a no difference in mean time to adjuvant therapy (83.5 days vs 72.6 days, P = 0.67). At esophagectomy centers with low anastomotic leak rates, cessation of routine j-tube placement at time of minimally esophagectomy can be undertaken without increasing risk of readmission, time until initiation of adjuvant therapy, or significantly impacting postoperative BMI loss.

Nasogastric tube drainage and pyloric intervention after oesophageal resection: UK practice variation and effect on outcomes

BACKGROUND

Over 1500 patients with oesophageal cancer undergo a resection in the UK each year. At surgery, patients commonly have a nasogastric tube (NGT) placed and may undergo a pyloric intervention. There is conflicting evidence on the use of both NGTs and pyloric interventions during oesophageal resections. We performed a national survey of oesophageal centres and assessed practice variation.

MATERIAL AND METHODS

An electronic survey was distributed to all resection centres in England, Wales and Scotland. Variations in practice regarding NGTs and pyloric intervention were assessed, and compared to nationally reported centre volumes and length-of-stay data.

RESULTS

Most centres (31/39, 79%) responded to the survey. All centres reported routine NGT use. The majority of centres (19/31, 61%) did not perform pyloric interventions. When used, surgical pyloroplasty was the most frequent strategy (8/31, 26%). Routine post-operative radiological assessment was utilised in 9/31 (29%) of centres. Criteria for NGT removal and dietary progression was highly variable, with every centre reporting different protocols. There were no significant differences in practice between high and low volume centres. There were also no trends seen when comparing centres above vs at-or-below the median length-of-stay. The majority (68%) of centres were willing to take part in a trial assessing NGT use and pyloric interventions.

CONCLUSIONS

Pyloric intervention use varies widely, with no clear link to outcomes. NGT use remains standard practice despite evidence for safe omission. Surgeons require and recognise the need for a trial to assess requirement for NGTs and pyloric intervention after oesophageal resection.

Long-Term Insufficiency of Oral Intake after Esophagectomy; Who Needs Intense Nutritional Support after Esophagectomy?

BACKGROUND

Patients with esophageal cancer are at a high risk of malnutrition after esophagectomy, and nutritional support may at times be required for several months following surgery. In this study, we aimed to clarify the clinical features and preoperative risk factors of patients with long-term insufficiency of oral intake after esophagectomy by evaluating the duration of feeding enterostomy placement.

METHODS

A total of 306 patients who underwent esophagectomy, reconstruction with gastric conduit, and feeding enterostomy creation were retrospectively reviewed. We analyzed the clinical features and preoperative risk factors for long-term placement of feeding enterostomy.

RESULTS

The feeding enterostomy tube was removed less than 90 days after esophagectomy in 234 patients (76.5%) (Short group), whereas 72 patients still needed enteral nutrition after 90 days (23.5%; Long group). Although severe malnutrition was observed more frequently in the long group compared with the short group (p=0.021), overall survival time was comparable between the groups (p=0.239). Multivariate analysis revealed that higher age (OR 1.04; 95% CI, 1.01-1.07; p=0.021), poor performance status(OR 2.94; 95% CI, 1.10-7.87; p=0.032), and lower preoperative body weight(OR 0.96; 95% CI, 0.94-0.99; p=0.009) were the independent variables predicting the long-time placement of feeding enterostomy.

CONCLUSION

Nutritional support via feeding enterostomy for more than 90 days after esophagectomy was required in 23.5% of patients. The elderly, poor performance status, and lower body weight were the independent preoperative factors for predicting the long-term placement of feeding enterostomy.

Early versus the traditional start of oral intake following esophagectomy for esophageal cancer: a systematic review and meta-analysis

BACKGROUND

Nil by mouth is considered the standard of care during the first days following esophagectomy. However, with the routine implementation of enhanced recovery after surgery, early oral intake is more likely to be the preferred mode of nutrition following esophagectomy. The present study aims to evaluate the safety and effectiveness of early oral intake following esophagectomy for esophageal cancer.

METHODS

Comprehensive literature searches were conducted using PubMed, Web of Science, Embase, and Cochrane Library. Weighted mean differences (WMD) and odds ratios (OR) with 95% confidence intervals (CI) were calculated as the effect sizes for continuous and dichotomous variables, respectively.

RESULTS

Fourteen studies with a total of 1947 patients were included. Length of hospital stay (WMD =  - 3.94, CI: - 4.98 to - 2.90; P < 0.001), the time to first flatus (WMD =  - 1.13, CI: - 1.25 to - 1.01; P < 0.001) and defecation (WMD =  - 1.26, CI: - 1.82 to - 0.71; P < 0.001) favored the early oral intake group. There was no statistically significant difference in mortality (OR = 1.23, CI: 0.45 to 3.36; P = 0.69). Early oral intake also did not increase the risk of pneumonia and overall postoperative complications.

CONCLUSIONS

Current evidence indicates early oral intake following esophagectomy seems to be safe and effective. It may be the preferred mode of nutrition following esophagectomy. However, more high-quality studies are still needed to further validate this conclusion.

Risk Factors for Failure of Direct Oral Feeding Following a Totally Minimally Invasive Esophagectomy

Recently, it has been shown that directly starting oral feeding (DOF) from postoperative day one (POD1) after a totally minimally invasive Ivor-Lewis esophagectomy (MIE-IL) can further improve postoperative outcomes. However, in some patients, tube feeding by a preemptively placed jejunostomy is necessary. This single-center cohort study investigated risk factors associated with failure of DOF in patients that underwent a MIE-IL between October 2015 and April 2021. A total of 165 patients underwent a MIE-IL, in which DOF was implemented in the enhanced recovery after surgery program. Of these, 70.3% (n = 116) successfully followed the nutritional protocol. In patients in which tube feeding was needed (29.7%; n = 49), female sex (compared to male) (OR 3.5 (95% CI 1.5–8.1)) and higher ASA scores (III + IV versus II) (OR 2.2 (95% CI 1.0–4.8)) were independently associated with failure of DOF for any cause. In case of failure, this was either due to a postoperative complication (n = 31, 18.8%) or insufficient caloric intake on POD5 (n = 18, 10.9%). In the subgroup of patients with complications, higher ASA scores (OR 2.8 (95% CI 1.2–6.8)) and histological subtypes (squamous-cell carcinoma versus adenocarcinoma and undifferentiated) (OR 5.2 (95% CI 1.8–15.1)) were identified as independent risk factors. In the subgroup of patients with insufficient caloric intake, female sex was identified as a risk factor (OR 5.8 (95% CI 2.0–16.8)). Jejunostomy-related complications occurred in 17 patients (10.3%). In patients with preoperative risk factors, preemptively placing a jejunostomy may be considered to ensure that nutritional goals are met.

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.

Transgastric Feeding Tube Insertion into the Jejunum after Esophagectomy: Direct Puncture of the Gastric Conduit

PURPOSE

To evaluate the safety and efficacy of percutaneous ultrasound (US)-guided direct puncture of a reconstructed gastric conduit after esophagectomy for performing a percutaneous radiologic gastrojejunostomy.

MATERIALS AND METHODS

Between 2014 and 2020, 26 consecutive patients with esophageal cancer (mean age, 70 years ± 8.3) with a total of 27 attempts of percutaneous radiologic gastrojejunostomy for postsurgical enteral feeding at the National Cancer Center Hospital were included in this study. One patient required a repeat procedure because of persistent anorexia after the removal of the first tube. All patients except 1 had a gastric conduit reconstructed via a retrosternal route. All procedures were performed under local anesthesia with moderate sedation and analgesia. A gastric conduit was directly punctured with an 18-gauge needle under ultrasonographic guidance, followed by feeding tube insertion into the proximal jejunum. Technical details of the procedures, technical success (defined as adequate tube placement), procedure-related complications, and clinical outcomes were reviewed.

RESULTS

The mean procedure time was 25 minutes ± 15, and technical success was obtained in every attempt. Minor complications included mild local pain (n = 7), unintentional tube removal (n = 2), local abdominal wall hematoma (n = 1), and superficial cellulitis (n = 1); no major complications were observed. During a mean follow-up period of 118.3 days ± 85.8, 13 patients resumed oral intake, and the feeding tube could be removed in 4 patients. No procedure-related deaths occurred.

CONCLUSIONS

The US-guided direct puncture technique is feasible for percutaneous gastrojejunal tube insertion in postsurgical patients with esophageal cancer with gastric conduit reconstruction.

Preoperative nutritional counselling in patients undergoing oesophagectomy

BACKGROUND

Patients undergoing surgery for oesophageal cancer are at high risk of malnutrition due to pathology and neoadjuvent therapy. This study sought to determine if oesophageal cancer patients undergoing oesophagectomy achieve superior clinical outcomes when preoperative nutritional counselling is performed.

METHODS

Oesophageal cancer patients undergoing oesophagectomy were retrospectively divided into cohorts based on those who received (n = 48) and did not receive (n = 58) preoperative nutritional counselling. We compared weight loss, length of stay, 30-day readmission related to nutrition or feeding tube problems, and 90-day mortality.

RESULTS

Per cent weight loss was less in patients who received preoperative nutritional counselling. There was a trend toward decreased mean length of stay and there were fewer readmissions for feeding tube-related complications in patients who received counselling.

CONCLUSIONS

Nutritional counselling before surgery may lead to decreased weight loss and reduced readmissions for feeding tube-related complications in patients with oesophageal cancer undergoing oesophagectomy.

Therapeutic Effect and Cost-Benefit Analysis of Three Different Nutritional Schemes for Esophageal Cancer Patients in the Early Post-operative Period

Objective: To retrospectively investigate the comparative efficacy, safety and cost-benefits of three nutritional treatment schemes including short peptide jejunal nutrition (SPJN), whole protein jejunal nutrition (WPJN), and partial parenteral nutrition (PPN) in patients underwent esophagectomy for esophageal cancer in our hospital. This study was carried out in accordance with the conceptual framework of nutritional therapy in fast-track rehabilitation surgery.

Methods: We retrospectively reviewed 305 patients who were assigned to receive esophagectomy for esophageal cancer. Eligible patients was naturally divided into SPJN group [n = 98 (32.1%)], WPJN group [n = 95 (31.1%)], and PPN group [n = 112 (36.7%)] according to the type of nutritional scheme which was actually prescribed to patients by the attendingphysician in clinical practice. The differences of the serum total protein (TP), albumin (ALB), pre-albumin (PA), hemoglobin (HGB), white blood cells (WBCs), red blood cells (RBCs) and neutrophils were compared among 3 nutritional schemes groups. We also investigated the relationship of the fluid intake, urine output, gastric juice drainage volume and thoracic drainage volume among 3 nutritional groups at 3 days after surgery. Moreover, the differences of cost-benefit indexes, complications, length of hospitalization and hospital expenditure were also compared.

Results: The serum TP, ALB, and PA in the SPJN group were all higher than those in the WPJN and PPN groups (p < 0.05). The gastric juice volume of gastrointestinal decompression drainage and fluid volume of thoracic drainage in the SPJN group were all less than that in the WPJN group (p < 0.05). The overall hospital stay and post-operative hospital stay in the SPJN group were all shorter than that in WPJN group (p < 0.05). Moreover, the incidence of post-operative complications including anastomotic leakage, infection, and gastrointestinal reaction was remarkably lower in the SPJN group compared to the WPJN group (p < 0.05). Interesting, hospital expenditure in the PPN group was less than that in the SPJN and the WPJN groups (p < 0.001).

Conclusion: Patients may obtain benefits in improving protein level after receiving SPJN scheme at the early stage after esophagectomy. Meanwhile, patients may obtain benefits in improving post-operative complications and hospital stay after receiving SPJN or PPN compared to WPJN protocol. However, the difference between SPJN and PPN requires further study because no difference was detected in terms of clinical outcomes including complications and the length of hospitalization although PPN may achieve a possible decrease of medical expenditure.

Early postoperative feeding following surgery for upper gastrointestinal cancer: A systematic review

Nutrition post major upper gastrointestinal (UGI) cancer surgery is a significant consideration known to affect postoperative recovery and the ability to tolerate adjuvant treatment. This systematic review assessed the effect of early oral feeding (EOF), compared to traditional timing of oral feeding, following major surgery for UGI cancer on postoperative complications, postoperative length of hospital stay (LOS), nutritional status and quality of life (QOL). The literature was searched up to March 9th 2020 using CINHAL, PubMed, MEDLINE, Embase, Scopus and Web of Science databases. Quality assessment was completed using the Academy of Nutrition and Dietetics quality criteria checklist. Fifteen articles were included, consisting of seven randomised controlled trials, six cohort studies and two non-randomised trials, with a total of 2517 participants. The type and timing of EOF varied considerably across studies with limited reporting of energy and protein intakes from oral or enteral feeding. Fourteen studies assessed postoperative complications of which 13 reported no difference between EOF and standard care. Fourteen studies assessed postoperative LOS and of these, 13 reported a reduced length of stay in the EOF group. Four of 15 studies assessing nutritional status found no difference between groups. Three of 15 studies assessed QOL with inconsistent findings. This review found EOF reduced postoperative LOS and did not increase postoperative complications. However, the optimal timing for the introduction of EOF could not be established. Furthermore, the type of EOF varied considerably making comparison across studies challenging and demonstrates a need for internationally standardised definitions.

Utility of feeding jejunostomy in patients with esophageal cancer undergoing esophagectomy with a high risk of anastomotic leakage

BACKGROUND

Feeding jejunostomy is widely used for enteral nutrition (EN) after esophagectomy; however, its risks and benefits are still controversial. We aimed to evaluate the short-term and long-term outcomes of feeding jejunal tube (FJT) in patients undergoing esophagectomy for esophageal squamous cell carcinoma (ESCC) who were deemed high-risk for anastomotic leakage.

METHODS

We retrospectively analyzed 716 patients who underwent esophagectomy with (FJT group, n=68) or without (control group, n=648) intraoperative placement of FJT. Propensity score matching (PSM) was used for the adjustment of confounding factors. Risk level for anastomotic leakage was determined for every patient after PSM.

RESULTS

Patients in the FJT group were at higher risk of anastomotic leakage (14.9% vs. 11.3%), and had a statistically non-significant increase of postoperative complications [31.3% vs. 21.8%, odds ratio (OR) =1.139, 95% confidence interval (CI), 0.947-1.370, P=0.141] after PSM. Medical expenditure, length of postoperative hospital stay, and short-term mortality were similar between the FJT and control groups. Placement of FJT appeared to accelerate the recovery of anastomotic leakage (27.2 vs. 37.4 d, P=0.073). Patients in FJT group achieved comparable overall survival (OS) both before [hazard ratio (HR) =0.850, P=0.390] and after (HR =0.797, P=0.292) PSM.

CONCLUSIONS

FJT showed acceptable safety profile along with potential benefits for ESCC patients with a high presumed risk of anastomotic leakage. While FJT does not impact OS, placement of FJT should be considered in esophagectomy patients and tailored to individual patients based on their leak-risk profile.

Effect of postoperative early enteral nutrition on clinical outcomes and immune function of cholangiocarcinoma patients with malignant obstructive jaundice

BACKGROUND

Most cholangiocarcinoma patients with malignant obstructive jaundice (MOJ) have varying degrees of malnutrition and immunodeficiency preoperatively. Therefore, perioperative nutritional support has important clinical significance in the treatment of cholangiocarcinoma.

AIM

To investigate the effects of postoperative early enteral nutrition (EEN) on immunity function and clinical outcomes of cholangiocarcinoma patients with MOJ.

METHODS

This prospective clinical study included 60 cholangiocarcinoma patients with MOJ who underwent surgery. The patients were randomly divided into an experimental group and a control group according to the nutrition support modes. The control group received postoperative total parenteral nutrition (TPN), whereas the experimental group received postoperative EEN and parenteral nutrition (PN; EEN + PN). The clinical outcomes, postoperative immune function, incidences of surgical site infection and bile leakage, intestinal function recovery time, average hospitalization days, and hospitalization expenses of the two groups were assessed on postoperative days (PODs) 1, 3, and 7.

RESULTS

The CD3+T, CD4+T, CD8+T, and CD4+T/CD8+T cell count and the immunoglobulin (Ig) G, IgM, and IgA levels in the EEN + PN group were significantly higher than those in the TPN group on PODs 3 and 7 (P < 0.05), whereas no significant differences in the CD3+T, CD4+T, CD8+T, and CD4+T/CD8+T cell counts and IgG, IgM, and IgA levels before operation and on POD 1 were found between the two groups (P > 0.05). The intestinal function recovery time and postoperative hospital stay were shorter (P < 0.001 for both) in the EEN + PN group than in the TPN group. The hospitalization expenses of the EEN + PN group were lower than those of the TPN group (P < 0.001). However, the incidence of abdominal distension was higher than in the EEN + PN group than in the TPN group (P < 0.05). The incidence rates of biliary leakage and surgical site infection were not significantly different between the two groups (P > 0.05).

CONCLUSION

A postoperative EEN program could reduce the incidence of postoperative complications and improve the clinical outcomes and immune functions of cholangiocarcinoma patients with MOJ and is thus beneficial to patient recovery.

Platelet-to-lymphocyte ratio is correlated with a delay in feeding resumption following a transhiatal esophagectomy with cervical anastomosis

Introduction

The lymphocytic population, neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR) are prognostic tools predictive of adverse outcomes for several solid tumors and oncologic surgeries, one of which is esophageal adenocarcinoma. Furthermore, delayed resumption of oral feeding postoperatively is associated with significant morbidity. Given the controversies regarding post-op nutritional support in these patients, this study investigates the prognostic role of the lymphocytic percentage, the NLR, and the PLR in predicting prolonged length of hospital stay (LOHS) and ICU stay (LOICUS) as well as delayed oral feeding following transhiatal esophagectomy (THE) for adenocarcinoma of the esophagogastric junction (AEG).

Methods

Forty consecutive patients who underwent transhiatal esophagectomy performed by a single surgeon for Siewert type II and type III adenocarcinoma of the esophagogastric junction at a tertiary referral center were selected. Retrospective data collection was performed from the patients’ medical records, and statistical analysis was performed using Pearson correlation and Student’s t test and Chi-square testing.

Results

An increased LOHS was correlated with a lower preoperative lymphocyte percentage (p = 0.043), higher NLR (p = 0.010) and PLR (p = 0.015), and an increased number of packed red blood cell (PRBC) transfusions perioperatively (p = 0.030). An increased LOICUS was correlated with a lower preoperative lymphocyte percentage (p = 0.033), higher NLR (p = 0.018) and PLR (p = 0.044), an increased number of PRBC transfusions (p = 0.001), and patients’ comorbidities (p < 0.05). A delay in feeding resumption was correlated with a lower preoperative lymphocyte percentage (p = 0.022), higher NLR (p = 0.004) and PLR (p = 0.001), an increased PRBC transfusions (p = 0.001), and diabetes mellitus (p = 0.033). Multivariate analysis with automatic linear modeling showed that only the preoperative PLR was a powerful predictor for the delay of feeding resumption (p < 0.01).

Conclusion

The lymphocyte percentage, PLR, and NLR are found to be associated with prolonged hospitalization and ICU stay and delayed oral feeding following THE for Siewert types II and III AEG. We hope by this series, to have set, at least one preliminary cornerstone, in the creation of a prognostic model, capable of assessing the need for an intraoperative jejunostomy placement, in patients undergoing esophagectomy for distal esophageal carcinoma.

Surgical Adjuncts During Esophagectomy

Esophagectomy is a major operation whereby intraoperative technique and postoperative care must be optimal. Even in expert hands, the complication rate is as high as 59%. Here the authors discuss the role of surgical adjuncts, including enteral access, nasogastric decompression, pyloric drainage procedures, and anastomotic buttressing as adjuncts to esophagectomy and whether they reduce perioperative complications.

The effect of early oral feeding after esophagectomy on the incidence of anastomotic leakage: an updated review

OBJECTIVE

Early oral feeding (EOF) is considered to be an important component of enhanced recovery after surgery (ERAS), but raises the concern of increased risk of anastomotic leakage (AL) in patients receiving esophagectomy. This review aimed to elucidate the correlation of EOF and the incidence of AL after esophageal resection.

METHODS

We searched PubMed, Web of Science, Scopus, Cochrane Library and Google Scholar from their inception to February 2020 for published articles that compared AL after EOF (oral feeding initiated within postoperative day [POD] 3) vs. conventional feeding regimen (nil-by-mouth with enteral tube nutrition support, until oral feeding since POD 4 and beyond) following esophagectomy.

RESULTS

A total of 11 full articles were included in this review, including 5 registered randomized controlled trials (RCTs) and 6 observational studies that compared EOF with conventional care after esophagectomy. Meta-analysis was not possible due to significant heterogeneity, bias, and small sample sizes. Among the 11 included studies, 9 (including the 5 RCTs) showed that EOF did not increase AL rate, whereas the other 2 retrospective studies indicated that delayed oral feeding resulted in fewer AL.

CONCLUSIONS

EOF after esophagectomy probably does not increase the incidence of AL, and it is a promising strategy in line with the essence of ERAS. However, more and better evidence from high-quality RCTs are still needed.
