Palliative venting percutaneous endoscopic gastrostomy tube is safe and effective in patients with malignant obstruction

American Society for Gastrointestinal Endoscopy guideline on gastrostomy feeding tubes: summary and recommendations

This clinical practice guideline from the American Society for Gastrointestinal Endoscopy (ASGE) provides an evidence-based approach for strategies to manage endoscopically placed gastrostomy tubes. This document was developed using the Grading of Recommendations Assessment, Development and Evaluation framework. The guideline addresses the utility of PEG versus interventional radiology-guided gastrostomy (IR-G), need for withholding antiplatelet and anticoagulant medications before PEG tube placement, appropriate timing to initiate tube feeding after PEG, and selection of the appropriate technique of gastrostomy in patients with malignant dysphagia. In patients needing enteral access, the ASGE suggests PEG as the preferred technique for initial gastrotomy over IR-G. The ASGE recommends that tube feeding can be safely started within 4 hours of gastrostomy. The ASGE suggests that PEG can be performed without withholding antiplatelet medications. The ASGE suggests that the periprocedural management of anticoagulants should be based on a multidisciplinary discussion regarding the risk of bleeding versus cardiovascular events. In patients with malignant dysphagia, either transoral "pull" PEG or direct PEG can be performed for initial enteral access.

Feasibility and benefit of decompressive percutaneous endoscopic gastrostomy (dPEG) in advanced cancer patients with malignant bowel obstruction

Background and study aims Bowel obstruction is a common complication in advanced cancer patients. Patients are restricted in quality of life (QOL) due to nausea, vomiting, or abdominal pain. Prospective data on the feasibility and benefit of decompressive percutaneous endoscopic gastrostomy (dPEG) are scarce. Patients and methods Patients suffering from symptomatic bowel obstruction due to advanced cancer were included prospectively in a single-center study when other treatments to eliminate the obstruction were impossible. Patients were given a questionnaire the day before dPEG (d-1) and, if the procedure was successful, the day after (d+1) and 14 days after the procedure (d14). Furthermore, lifetime after dPEG was assessed. Results 53 patients were included. dPEG was technically feasible in 34 of 53 (64.2%). Significant improvement could be shown for nausea and vomiting when comparing d-1 to d+1 (nausea ( P = 0.002), vomiting ( P < 0.001)) and when comparing d-1 to d14 ( P = 0.021 and P = 0.003, respectively). Comparing d+1 to d14, there was no further improvement. QOL improved significantly from 8.1 (mean) on d-1 to 5.9 (mean) on d+1 ( P < 0.001). Median survival after successful dPEG was 27 days (range 2-353). Conclusions dPEG is an effective method for quickly relieve symptoms of malignant bowel obstruction in advanced cancer patients. However, the technical success rate is limited and needs to be improved. Prospective studies comparing endoscopic and computed tomography-guided procedures are needed to avoid unsuccessful procedures in patients with advanced cancer and limited life expectancy.

Palliative Intervention for Malignant Bowel Obstruction Comes at a Cost: A National Inpatient Study

Background: Malignant bowel obstruction (MBO) due to peritoneal carcinomatosis (PC) is associated with poor outcomes. Optimal management for palliation remains unclear. This study aims to characterize nonoperative, procedural, and operative management strategies for MBO and evaluate its association with mortality and cost.Materials and Methods: ICD-10 coding identified patient admissions from the 2018 to 2019 National Inpatient Sample (NIS) for MBO with PC from gastrointestinal or ovarian primary cancers. Management was categorized as nonoperative, procedural, or surgical. Multivariate analysis was used to associate treatment with mortality and cost.Results: 356,316 patient admissions were identified, with a mean age of 63 years. Gender, race, and insurance status were similar among groups. Length of stay (LOS) was longest in the surgical group (surgical: 17 days; procedural: 14 days; nonoperative: 7 days; P = .001). In comparison to nonoperative, procedural and surgical patients had statistically higher hospital charges, post-discharge medical needs, palliative care consults, and admission to rehab centers. Mortality was 7% in nonoperative, 9% in procedural, and 8% in surgical (P = .007) groups. In adjusted analyses, older age, palliative care consult, and non-Medicare payer status were associated with higher mortality. Compared to nonoperative, procedural and surgical groups resulted in increased costs (procedural: $17K more; surgical: $30K more).Conclusions: Admissions for procedural and surgical treatment of MBO are associated with increased LOS, hospital costs, and discharge needs. Optimal management remains challenging. Clinicians must examine all options prior to recommending palliative interventions given a trend towards higher resource utilization and mortality.

Inoperable malignant bowel obstruction: palliative interventions outcomes - mixed-methods systematic review

BACKGROUND

Parenteral nutrition (PN) and palliative venting gastrostomies (PVG) are two interventions used clinically to manage inoperable malignant bowel obstruction (MBO); however, little is known about their role in clinical and quality-of-life outcomes to inform clinical decision making.

AIM

To examine the impact of PN and PVG on clinical and quality-of-life outcomes in inoperable MBO.

DESIGN

A mixed-methods systematic review and narrative synthesis.

DATA SOURCES

The following databases were searched (from inception to 29 April 2021): MEDLINE, Embase, Cochrane Central Register of Controlled Trials, Web of Science, CINAHL, Bielefeld Academic Search Engine, Health Technology Assessment and CareSearch for qualitative or quantitative studies of MBO, and PN or PVG. Titles, abstracts and papers were independently screened and quality appraised.

RESULTS

A total of 47 studies representing 3538 participants were included. Current evidence cannot tell us whether these interventions improve MBO survival, but this was a firm belief by patients and clinicians informing their decision. Both interventions appear to allow patients valuable time at home. PVG provides relief from nausea and vomiting. Both interventions improve quality of life but not without significant burdens. Nutritional and performance status may be maintained or improved with PN.

CONCLUSION

PN and PVG seem to allow valuable time at home. We found no conclusive evidence to show either intervention prolonged survival, due to the lack of randomised controlled trials that have to date not been performed due to concerns about equipoise. Well-designed studies regarding survival for both interventions are needed.

When Should the Appropriateness of PEG be Questioned?

PURPOSE OF REVIEW

This review aims to analyze the evidence regarding the appropriateness of PEG placement in the following clinical situations: short bowel syndrome, head and neck cancer, dementia and palliative use in malignant bowel obstruction.

RECENT FINDINGS

Percutaneous endoscopic gastrostomy (PEG) tubes are placed for a variety of clinical indications by numerous different specialties. First described in 1980, PEG tubes are now the dominant method of enteral access. Typically, PEG tubes are technically feasible procedures that can come with significant risk for both minor and major complications. Therefore, it is important to perform an in-depth, patient specific risk-benefit analysis when considering insertion. By analyzing the current evidence regarding benefits in these situations, superimposed by the lens of biomedical ethics, we make recommendations that are accessible to any provider who may be a consultant or proceduralist, helping to provide informed care that is in the patient's best interest.

The range and suitability of outcome measures used in the assessment of palliative treatment for inoperable malignant bowel obstruction: A systematic review

BACKGROUND

Malignant bowel obstruction, a complication of certain advanced cancers, causes severe symptoms which profoundly affect quality of life. Clinical management remains complex, and outcome assessment is inconsistent.

AIM

To identify outcomes evaluating palliative treatment for inoperable malignant bowel obstruction, as part of a four-phase study developing a core outcome set.

DESIGN

The review is reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA); PROSPERO (ID: CRD42019150648). Eligible studies included at least one subgroup with obstruction below the ligament of Treitz undergoing palliative treatment for inoperable malignant bowel obstruction. Study quality was not assessed because the review does not evaluate efficacy.

DATA SOURCES

Medline, Embase, the Cochrane Database, CINAHL, PSYCinfo Caresearch, Open Grey and BASE were searched for trials and observational studies in October 2021.

RESULTS

A total of 4769 studies were screened, 290 full texts retrieved and 80 (13,898 participants) included in a narrative synthesis; 343 outcomes were extracted verbatim and pooled into 90 unique terms across six domains: physiological, nutrition, life impact, resource use, mortality and survival. Prevalent outcomes included adverse events (78% of studies), survival (54%), symptom control (39%) and mortality (31%). Key individual symptoms assessed were vomiting (41% of studies), nausea (34%) and pain (33%); 19% of studies assessed quality of life.

CONCLUSIONS

Assessment focuses on survival, complications and overall symptom control. There is a need for definitions of treatment 'success' that are meaningful to patients, a more consistent approach to symptom assessment, and greater consideration of how to measure wellbeing in this population.

MASCC multidisciplinary evidence-based recommendations for the management of malignant bowel obstruction in advanced cancer

PURPOSE

To provide evidence-based recommendations on the management of malignant bowel obstruction (MBO) for patients with advanced cancer.

METHODS

The Multinational Association for Supportive Care in Cancer (MASCC) MBO study group conducted a systematic review of databases (inception to March 2021) to identify studies about patients with advanced cancer and MBO that reported on the following outcomes: symptom management, bowel obstruction resolution, prognosis, overall survival, and quality of life. The review was restricted to studies published in English, but no restrictions were placed on publication year, country, and study type. As per the MASCC Guidelines Policy, the findings were synthesized to determine the levels of evidence to support each MBO intervention and, ultimately, the graded recommendations and suggestions.

RESULTS

The systematic review identified 17,656 published studies and 397 selected for the guidelines. The MASCC study group developed a total of 25 evidence-based suggestions and recommendations about the management of MBO-related nausea and vomiting, bowel movements, pain, inflammation, bowel decompression, and nutrition. Expert consensus-based guidance about advanced care planning and psychosocial support is also provided.

CONCLUSION

This MASCC Guideline provides comprehensive, evidence-based recommendations about MBO management for patients with advanced cancer.

Gastric Cancer, Version 2.2022, NCCN Clinical Practice Guidelines in Oncology

Gastric cancer is the third leading cause of cancer-related deaths worldwide. Over 95% of gastric cancers are adenocarcinomas, which are typically classified based on anatomic location and histologic type. Gastric cancer generally carries a poor prognosis because it is often diagnosed at an advanced stage. Systemic therapy can provide palliation, improved survival, and enhanced quality of life in patients with locally advanced or metastatic disease. The implementation of biomarker testing, especially analysis of HER2 status, microsatellite instability (MSI) status, and the expression of programmed death-ligand 1 (PD-L1), has had a significant impact on clinical practice and patient care. Targeted therapies including trastuzumab, nivolumab, and pembrolizumab have produced encouraging results in clinical trials for the treatment of patients with locally advanced or metastatic disease. Palliative management, which may include systemic therapy, chemoradiation, and/or best supportive care, is recommended for all patients with unresectable or metastatic cancer. Multidisciplinary team management is essential for all patients with localized gastric cancer. This selection from the NCCN Guidelines for Gastric Cancer focuses on the management of unresectable locally advanced, recurrent, or metastatic disease.

Considerations in the Management of Malignant Bowel Obstruction

Malignant bowel obstruction is a challenging clinical problem encountered in patients with advanced abdominal and pelvic malignancies. Although medical therapies form the foundation of management, some patients may be suitable candidates for surgical and procedural interventions. The literature is composed primarily of retrospective single-institution experiences and the results of prospective trials are pending. Given the high symptom burden and limited life expectancy of these patients, management may be best informed by multidisciplinary teams with relevant expertise.

Gastrostomy Tube for Nutrition and Malignant Bowel Obstruction in Patients With Cancer

BACKGROUND

Gastrostomy tubes (G-tubes) are invaluable clinical tools that play a role in palliation and nutrition in patients with cancer. This study aimed to better understand the risks and benefits associated with the placement and maintenance of G-tubes.

METHODS

Patients who underwent placement of a G-tube for cancer from January 2013 through December 2017 at a tertiary care center were considered for inclusion. Clinical data were retrospectively collected from medical records.

RESULTS

A total of 242 patients with cancer, whose average age at diagnosis was 61 years (range, 21-94 years), underwent G-tube placement for nutrition (76.4%), decompression (22.7%), or both (0.8%). Successful insertion was achieved in 96.8%, but 8 patients required >1 attempted method of insertion. In the decompression group, minor postplacement complications were less common (23.6% vs 53.5%; P<.001) and survival was shorter (P<.001) compared with the nutrition group. For those with decompressive G-tubes, 45.5% had a palliative care consult; 56.4% were seen by social workers; and 46.3% went to hospice. The frequency of hospice discharge was higher in patients who had consults (53.7% vs 23.1%; P=.01).

CONCLUSIONS

Half of the patients who received decompressive G-tubes presented with stage IV disease and died within 1 month of placement. Those with >1 consult were more likely to be discharged to hospice. Patients with G-tubes for nutrition saw no change in functionality, complication rate, or survival, regardless of adjunct chemotherapy status. These findings illustrate the need for a tool to allow a better multidisciplinary approach and interventional decision-making for patients with cancer.

Narrative review of the role of gastroenterologist in the diagnosis, treatment and palliation in gastric and gastroesophageal cancer

Esophageal cancer (EC) and gastric cancer (GC) carry a high mortality rate. Unfortunately, a majority of patients are asymptomatic and at the time of diagnosis, the disease may invariably be in its advanced stages with limited curative options. Thus, it is imperative to recognize certain risk factors including gastroesophageal reflux disease (GERD), male gender, pre-existing Barrett’s esophagus, smoking history, obesity, Helicobacter pylori infection, atrophic gastritis among others for both EC and GC, intervene on time with screening and surveillance modalities if indicated and optimize treatment plans. With advances in endoscopic techniques, early neoplastic lesions are increasingly managed by gastroenterologists, offering an alternative to surgery. The gold standard for diagnosis of EC and GC is high definition endoscopy with adequate targeted biopsies. Endoscopic ultrasound (EUS) is a key in the staging of early cancers dictating the pathway for treatment options. We also play a key role in palliation cases with the aim to reduce the symptoms like nausea, vomiting and even when possible, restore oral intake and improve nutrition in both advanced GC and EC. This review article discusses the risk factors, diagnostic and endoscopic treatment modalities of early EC and GC and palliation of advanced cancer where gastroenterologists play a key role.

Illness Understanding, Prognostic Awareness, and End-of-Life Care in Patients With GI Cancer and Malignant Bowel Obstruction With Drainage Percutaneous Endoscopic Gastrostomy

PURPOSE

Malignant bowel obstruction (MBO) is common in advanced GI cancer, and MBO management, including drainage percutaneous endoscopic gastrostomy (dPEG), is palliative. How patients understand the goals of dPEG and its impact on disease is inadequately understood in the literature. Therefore, we analyzed these issues in patients with GI cancer.

METHODS

Demographics, clinical variables, and patient outcomes were abstracted from the medical record. Illness understanding and future expectations were retrieved from palliative care notes. We described additional treatment and outcomes after dPEG and estimated overall survival (OS).

RESULTS

From January 2015 to June 2017, 125 admitted patients with metastatic GI cancer underwent dPEG for MBO. Cancers were most commonly colorectal (34%) and pancreatic/ampullary (25%). During the dPEG admission, 32% (40 of 125) of patients had a palliative care consultation, and 22% (28 of 125) were asked about illness understanding and future expectations. All (28 of 28) reported good understanding of the advanced nature of their disease, but few were accurate about prognosis given their stage IV disease (10 of 28). Of the 117 (94%) discharged, 13% (15 of 117) received additional chemotherapy, which rarely prevented progression; half (63 of 117) had a do-not-resuscitate order; and most (101 of 117) were enrolled in hospice at death. Median time to death was 37 days (95% CI, 29 to 45 days); 6-month OS was 3.7% (95% CI, 1.2% to 8.4%).

CONCLUSION

dPEGs are placed close to end of life in patients with advanced GI cancer. A minority of patients receive additional chemotherapy post-dPEG. Many have adequate disease understanding, but chemotherapy benefit is low, and future expectations vary. This may be an opportunity for improved communication regarding palliative procedures in advanced cancer.

Safety and Efficacy of Venting Gastrostomy in Malignant Bowel Obstruction: A Systematic Review

Malignant bowel obstruction (MBO) is a common manifestation in patients with advanced intra-abdominal malignancy. It is especially common with bowel or gynecological cancers and produces distressing symptoms, including nausea, vomiting, and pain. Medical management options are less effective than decompressive strategies for symptom control. Surgery is the gold-standard treatment but is unsuitable for most patients with high complication rates. Consensus guidelines recommend nonsurgical management with a venting gastrostomy in those unsuitable for surgery or for whom medical management is ineffective. The aim of this systematic review is to establish the safety and efficacy of percutaneous venting gastrostomy in relieving symptoms of MBO. Twenty-five studies were included in this review comprising 1194 patients. Gastrostomy insertion was successful at first attempt in 91% of cases and reduction in symptoms of nausea and vomiting was reported in 92% of cases. Mean survival following the procedure ranged from 35 to 147 days. Major complications were rare, with most complications classed as minor wound infections or leakage of fluid around the tube. Studies suggest that the presence of ascites is not an absolute contraindication to the insertion of percutaneous venting gastrostomy in patients with MBO; however, these studies lack longitudinal outcomes and complication rates related to this. However, it is reasonable to suggest that ascitic drainage is performed to reduce potential complications. There is a relative lack of good quality robust data on the utilization of percutaneous venting gastrostomy in MBO, but overall, the combination of being a safe and efficacious procedure alongside the known complication profile suggests that it should be considered a suitable management option.

Palliative Management of Advanced Peritoneal Carcinomatosis

Despite advances in the management of peritoneal carcinomatosis, morbidity remains high with survival often measured in weeks to months. Patients are often subjected to symptoms and complications that impact quality of life. Much of the management revolves around palliation of symptoms and providing support and resources to address emotional and existential concerns. This article reviews surgical and nonsurgical palliative treatments for the symptoms and complications associated with advanced, incurable peritoneal carcinomatosis. It is important that providers caring for patients with peritoneal carcinomatosis be knowledgeable in the palliative management of this condition, including the usefulness of early palliative care referral.

Which G-Tube to Use in Pullers: Assessment of Pull Pressures on Skin Models to Determine Optimal Catheter Choice in Patients with Recurrent Pulled Gastrostomy Tubes

INTRODUCTION

Pulled or dislodged gastrostomy catheters represent a common complication associated with percutaneous gastrostomy and are a common cause of recurrent visits in patients with altered mental status. We intended to perform an experiment to compare the pull forces required to dislodge different commonly used gastrostomy catheters.

MATERIALS AND METHODS

We used a digital force gauge device to measure the pull forces required to dislodge three types of 20 French gastrostomy catheters in double-layer skin models. These included the Flow 20 Pull Method (Cook Medical, Bloomington, IN, USA), Entuit Gastrostomy BR Balloon Retention feeding tube (Cook Medical, Bloomington, IN, USA), and Ponsky Non-Balloon Replacement Gastrostomy Tube (CR Bard Inc, Salt Lake City, Utah, USA). The catheters were inserted into the skin model using the same technique as would be utilized in a patient.

RESULTS

The mean forces measured to dislodge the per-oral Flow 20 Pull Method, Entuit Thrive Balloon Retention, and button-type retention Ponsky replacement catheters were 35.6, 22.8, and 20.6 Newtons, respectively. The pull method per-oral gastrostomy catheter required significantly more pull force to dislodge than both the Ponsky button-type retention catheter and the Entuit balloon retention catheters. There was no significant difference in the pull force required to dislodge the Ponsky replacement catheter and the Entuit balloon retention catheter.

CONCLUSIONS

Per-oral image-guided gastrostomy with pull-method button-type retention catheters may be the ideal choice in patients at high risk of tube dislodgment.

Survival, Healthcare Utilization, and End-of-life Care Among Older Adults With Malignancy-associated Bowel Obstruction: Comparative Study of Surgery, Venting Gastrostomy, or Medical Management

OBJECTIVE

To compare survival, readmissions, and end-of-life care after palliative procedures compared with medical management for malignancy-associated bowel obstruction (MBO).

BACKGROUND

MBO is a late complication of intra-abdominal malignancy for which surgeons are frequently consulted. Decisions about palliative treatments, which include medical management, surgery, or venting gastrostomy tube (VGT), are hampered by the paucity of outcomes data relevant to patients approaching the end of life.

METHODS

Retrospective study using 2001 to 2012 Surveillance, Epidemiology, and End Results-Medicare data of patients 65 years or older with stage IV ovarian or pancreatic cancer who were hospitalized for MBO. Multivariate competing-risks regression models were used to compare the following outcomes: survival, readmission for MBO, hospice enrollment, intensive care unit (ICU) care in the last days of life, and location of death in an acute care hospital.

RESULTS

Median survival after MBO admission was 76 days (interquartile range 26-319 days). Survival was shorter after VGT [38 days (interquartile range 23-69)] than medical management [72 days (23-312)] or surgery [128 days (42-483)]. As compared to medical management, patients treated with VGT had fewer readmissions [subdistribution hazard ratio 0.41 (0.29-0.58)], increased hospice enrollment [1.65 (1.42-1.91)], and less ICU care [0.69 (0.52-0.93)] and in-hospital death [0.47 (0.36-0.63)]. Surgery was associated with fewer readmissions [0.69 (0.59-0.80)], decreased hospice enrollment [0.84 (0.76-0.92)], and higher likelihood of ICU care [1.38 (1.17-1.64)].

CONCLUSIONS

VGT is associated with fewer readmissions and lower intensity healthcare utilization at the end of life than do medical management or surgery. Given the limited survival, regardless of management, hospitalization with MBO carries prognostic significance and presents a critical opportunity to identify patients' priorities for end-of-life care.

Bowel Obstruction: Decompressive Gastrostomies and Cecostomies

Over the past 30 years, image-guided placement of gastrostomies and cecostomies for gastrointestinal decompression has developed into a safe and effective treatment for symptomatic bowel obstruction. Gastrostomies and cecostomies relieve patient symptoms, can prevent serious complications such as colonic perforation, and may bridge patients to more definitive treatment for the underlying cause of obstruction. This article will review the history of decompressive gastrostomies and cecostomies as well as the indications, contraindications, technique, complications, and outcomes of these procedures.

Drainage Percutaneous Endoscopic Gastrostomy for Malignant Bowel Obstruction in Gastrointestinal Cancers: Prognosis and Implications for Timing of Palliative Intervention

BACKGROUND

Malignant bowel obstruction (MBO) is a frequent complication in patients with advanced solid tumors. Palliative relief may be achieved by the use of a drainage percutaneous endoscopic gastrostomy (dPEG) tube, although optimal timing of placement remains unknown.

OBJECTIVES

To determine median survival after diagnosis of MBO and dPEG placement, factors associated with worse survival in MBO, factors associated with receipt of dPEG, and association of timing of dPEG placement on survival.

METHODS

This observational retrospective cohort study examined 439 patients with MBO on a gastrointestinal medical oncology inpatient service. Patients were characterized by age, gender, race, primary cancer type, length of stay, readmission, complications (aspiration pneumonia or bowel perforation), and receipt of dPEG. Select factors were analyzed to examine overall survival (OS) and dPEG placement.

RESULTS

Median survival from diagnosis of first MBO was 2.5 months. Median survival after dPEG placement was 37 days. In univariate analysis, dPEG placement, complications, longer length of stay, and readmissions were significantly associated with worse OS. Receipt of dPEG was significantly associated with younger age, longer length of stay at first admission, and shorter interval to readmission. In patients who received dPEG, longer interval from MBO diagnosis to dPEG placement did not affect OS.

CONCLUSION

We found that prognosis following diagnosis of MBO in patients with gastrointestinal malignancies remains poor. Our data suggest that timing of dPEG placement in MBO does not affect OS and, therefore, earlier intervention with this procedure may allow earlier and prolonged palliative relief.

Cost-effectiveness of palliative surgery versus nonsurgical procedures in gastrointestinal cancer patients

Palliative care is an essential component to multidisciplinary cancer care. Improved symptom control, quality of life (QOL), and survival have resulted from its utilization. Cost-effectiveness and utility analyses are significant variables that should be considered in comparing benefits and costs of medical interventions to determine if certain treatments are economically justified. This is a review on the cost-effectiveness of palliative surgery compared to other nonsurgical palliative procedures in patients with unresectable gastrointestinal cancers. J. Surg.

ACG Clinical Guideline: Nutrition Therapy in the Adult Hospitalized Patient

The value of nutrition therapy for the adult hospitalized patient is derived from the outcome benefits achieved by the delivery of early enteral feeding. Nutritional assessment should identify those patients at high nutritional risk, determined by both disease severity and nutritional status. For such patients if they are unable to maintain volitional intake, enteral access should be attained and enteral nutrition (EN) initiated within 24-48 h of admission. Orogastric or nasogastric feeding is most appropriate when starting EN, switching to post-pyloric or deep jejunal feeding only in those patients who are intolerant of gastric feeds or at high risk for aspiration. Percutaneous access should be used for those patients anticipated to require EN for >4 weeks. Patients receiving EN should be monitored for risk of aspiration, tolerance, and adequacy of feeding (determined by percent of goal calories and protein delivered). Intentional permissive underfeeding (and even trophic feeding) is appropriate temporarily for certain subsets of hospitalized patients. Although a standard polymeric formula should be used routinely in most patients, an immune-modulating formula (with arginine and fish oil) should be reserved for patients who have had major surgery in a surgical ICU setting. Adequacy of nutrition therapy is enhanced by establishing nurse-driven enteral feeding protocols, increasing delivery by volume-based or top-down feeding strategies, minimizing interruptions, and eliminating the practice of gastric residual volumes. Parenteral nutrition should be used in patients at high nutritional risk when EN is not feasible or after the first week of hospitalization if EN is not sufficient. Because of their knowledge base and skill set, the gastroenterologist endoscopist is an asset to the Nutrition Support Team and should participate in providing optimal nutrition therapy to the hospitalized adult patient.

Percutaneous Endoscopic Gastrostomy for Decompression of Nonmalignant Gastrointestinal Disease

INTRODUCTION

The utility of percutaneous endoscopic gastrostomy (PEG) decompression for inoperable malignant bowel obstruction is well documented. However, there are limited data on decompressive PEG for prolonged ileus, gut dysmotility, and/or complicated nonmalignant bowel obstruction. The aim of this study was to assess the safety and short-term outcomes of decompressive PEG for nonmalignant indications.

SUBJECTS AND METHODS

After Institutional Review Board approval, we retrospectively reviewed and analyzed all PEG insertions completed at our institution between 2009 and 2014 for prolonged ileus, gut dysmotility, or nonmalignant obstruction.

RESULTS

We identified 72 patients (42 females, 30 males; mean age, 58.8 ± 15.2 years) who underwent decompressive PEG for nonmalignant indications. There were no procedural complications or mortalities. The mean pre- and postprocedural length of stays were 14.4 ± 10.7 and 7.6 ± 11.1 days, respectively (P = .0003). The 30-day re-admission rate was 12.5% (9 patients; the majority for unrelated issues). Fifty-two (72%) of the 72 patients were discharged with a PEG for decompression for a median of 69.5 (range, 17-316) days; the remaining 20 (28%) patients were lost to follow-up and were assumed to continue follow-up with their primary referring center. Of the 72 patients, 63 (87.5%) were discharged on total parenteral nutrition (TPN); 36 (50%) of those continued to receive TPN for a median of 51 (range, 4-316) days after discharge, and resolution of their mechanical obstruction was ultimately achieved, so that they subsequently resumed enteral nutrition. Twenty-four (33%) patients were lost to follow-up; because they were referred to our tertiary referral center, we assumed they continued follow-up at their referring institution. Three (4%) patients ultimately went on to use TPN indefinitely and thus were considered to be chronically TPN-dependent.

CONCLUSIONS

Decompressive PEG insertion is safe and effective at alleviating obstructive symptoms in patients with prolonged postoperative ileus, gut dysmotility, and/or complicated nonmalignant obstruction.
