Abstract

Background Gastrointestinal route is considered for feeding in subjects who are unable to swallow, either as a temporary or permanent option. Percutaneous endoscopic gastrostomy (PEG) is the preferred mode for long-term enteral nutrition. The aim was to study the outcome of protocol-based PEG placement in a tertiary medical center.

Materials and Methods All the patients who underwent PEG placement between January 2017 and December 2019 were included in the retrospective study. Study variables were entered into a uniform structured proforma. The procedure was done by two people using Ponsky-Gauderer pull-technique. Fluoroscopy guidance was considered for placement in special situations. Post-procedure, all the patients were regularly followed as per protocol to evaluate for adverse events.

Results One hundred and eighteen patients with placement of PEG were included in the study. The mean age of the patients was 49.6 ± 7 years with 67.8% males. The most common indication of PEG was inability to swallow associated with head injury (43, 36.4%), followed by carcinoma esophagus (35, 29.8%) and stroke (24, 20.3%). Fluoroscopy was useful in 38 (32%) for PEG site identification. Tube dislodgement (16, 13.5%) and aspiration pneumonia (20, 16.9%) were the common adverse events. Age more than 60 years and dysphagia in neurologic disorders accounted for more than 60% of adverse events. Forty-nine (42%) of the PEG patients expired due to either primary illness or due to sepsis after a median time of 139 days (range: 32–288 days). There was no difference in the survival in patients with or without PEG-related complications (p = 0. 74).

Conclusions Fluoroscopy assistance helps in accurate PEG placement in one third. Age > 60 years and dysphagia in neurologic disorders were independent risk factors associated with PEG tube complications.

Introduction

Percutaneous endoscopic gastrostomy (PEG) was first reported by Gauderer et al.[1] For enteral nutrition, PEG gained preference over the already established surgical or radiological gastrostomy due to superior outcome both in terms of morbidity and mortality.[2] [3] [4] For long-term nutrition in neurological dysphagia, PEG is preferred over nasogastric (NG) tube due to aesthetic appeal, avoidance of uncomfortable oropharyngeal symptoms, less chance of oropharyngeal candidiasis and respiratory infections, averting esophageal ulcer and stricture, and reduced risk of clogging or displacement of tube.[5] [6] [7] [8] Also, overnight feeding is safer with a PEG tube.[9]

In contrast to PEG, the placement of NG tube is relatively easy at the bedside by trained medical staff. The accuracy of NG tube position can be easily confirmed by auscultation over the upper abdomen on air insufflation through the tube or by aspiration of gastric contents and occasionally by radiographic examination.[10]

Although PEG placement is safe, it has both early and late complications like bleeding, peritonitis, bowel obstruction or perforation, and abscess at the operative site.[7] [11] [12] The reported PEG-related morbidity and mortality are 9–17% and 0–10%, respectively.[3] [13] The American Society of Gastrointestinal Endoscopy recommends PEG insertion in patients who are expected to survive longer than 1 month after the procedure.[14]

The use of fluoroscopy at PEG tube placement (F-PEG) is infrequently reported.[15] In patients with ventriculoperitoneal shunts, fluoroscopy assists in identifying and avoiding it, and helps select a suitable site for PEG placement. Fluoroscopy is also useful in patients having altered upper gastrointestinal (GI) anatomy, kyphoscoliosis, gastric volvulus, or pseudo-obstruction. It can occasionally help in confirming accidental colonic or small bowel injury during puncture and also aids in detection of any significant pneumo-peritoneum at the time of procedure.[16]

PEG remains an underutilized procedure in India, mainly due to lack of inclination or awareness among the treating physicians.[17] The aim of our study was to study the outcome of protocol-based PEG placement in a tertiary medical center.


#

Materials and Methods

Data was collected retrospectively for all the patients who underwent a PEG tube placement between January 2017 and December 2019 at our hospital. The study was approved by Institute Ethical Committee.

The baseline data points captured included age, gender, comorbidities, indications, and contraindications for PEG. Also, regular follow-up data was maintained (especially looking for adverse events associated with PEG), including its removal. The patients underwent the procedure after required informed consent. All the procedures were performed by the same endoscopic team under supervised anesthesia.

Inclusion Criteria

Patients presenting with neurological diseases having reduced level of consciousness (e.g., cerebrovascular disease, motor neuron disease, head injury), cancer of head and neck or esophagus, and gastric volvulus were included. All patients were on enteral feeds through a NG prior to PEG tube insertion. In gastric volvulus, fixation of anterior stomach wall to the abdominal wall was the primary aim to prevent recurrence. In patients on dual antiplatelets (aspirin and clopidogrel), clopidogrel was stopped 7 days before the procedure while continuing aspirin. Patients on warfarin were changed over to low molecular weight heparin for 5 days before the procedure. The last dose of heparin was given 12 hours before procedure and restarted after 6 hours, post-procedure.


#

Exclusion Criteria

Following are the exclusion criteria: Coagulopathy (International Normalized Ratio > 1.5, partial thromboplastin time > 50 seconds, platelets < 50,000/mm3), hemodynamic instability, sepsis, gross ascites, peritonitis, peritoneal carcinomatosis, history of total gastrectomy, gastric outlet obstruction, and lack of informed consent for the procedure. Those with documented fever or significant leucocytosis were excluded.


#

Technique

All the patients received betadine oral gargle on the night before procedure. After overnight fasting, oral cleansing was performed in the morning on the day of procedure. Prophylactic antibiotic was given before the procedure (1 gm of ceftriaxone/vancomycin).

The procedure was performed in an endoscopy room having fluoroscopy facility. PEG procedure was done by two people using Ponsky-Gauderer pull-technique using standard flexible endoscope (GIF–Q 150/H 180-Olympus, Tokyo, Japan) and 24Fr gastrostomy tube (Wilson-Cook, Winston-Salem, North Carolina, United States).[18] At endoscopy, luminal contents were cleared including from hypopharynx ([Fig. 1]).

In image (D), an Asepto pump was being used for home-based blenderized feeds.

A balloon replacement tube (BRT) was used for PEG exchange when required. The BRT tube was inserted at previous gastrostomy site and balloon was inflated to the capacity with prefilled syringes.


#

Post-PEG Care

Patients were kept nil orally after PEG procedure for 8 hours. Prior to PEG feeding, the tube site was inspected and free rotation of tube and the external bolster was confirmed. Tube feeding was started with 100 to 200 mL of clear liquids, after ensuring no abdominal pain, vomiting, or tube leakage as per protocol.[19] After 4 hours, PEG feeds were initiated in boluses of 250 mL in 20 minutes for every 4 hours. Flushing with 20 mL of water was done after every feeding. At discharge, the patients’ family were instructed about feeding, and made aware of potential PEG-related complications (mentioned below) and follow-up (either telephonically or physically) as per clinical requirement.

Aspiration pneumonia was defined by new development of chest symptoms (cough, purulent sputum, or fever after PEG) with changes in chest radiograph and/or oxygen saturation and/or witnessed aspiration.[20] Dislodgement was defined as complete inadvertent pulling out of gastrostomy tube.[20] Buried bumper syndrome (BBS) was considered when the inner bumper migrates alongside the stoma tract out of the gastric lumen and can be anywhere between the stomach mucosa and the surface of the skin. BBS was suspected when there was increased leakage around the PEG tube, along with pain or resistance to PEG feeding.[21] Peristomal infections (PSI) were defined as having at least two of the following: peristomal erythema, induration, purulent discharge with supportive laboratory evidence of infection/positive culture report.[22] [23] Positive culture growth but no clinical signs were regarded as colonization and were not included under PSI. Bleeding from the PEG tract was defined by bleeding from any side of the PEG tract that can present as external wound bleeding, subcutaneous hematoma at PEG site, melena or other forms of GI bleeding confirmed to be from PEG site on endoscopy and/or drop in hemoglobin concentration.[24] PEG tube obstruction was identified by inability to pass feed or flush water down the tube with no visible sign of tube kinking.[24]

The patients that recovered from primary illness and resumed oral intake had their PEG tube removed.

Statistical Analysis

Data were reported as mean ± standard deviation) for continuous variables and frequencies (percentages) for categorical variables. All analyses were performed using the SPSS statistical analysis software version 17.0 (SPSS Inc., Chicago, Illinois, United States). Survival was assessed using Kaplan–Meier curve after comparing median survival time using Koch's regression model. All tests were two-sided and statistical significance was defined as a p-value less than 0.05.

Results

Two hundred and seventy-five PEG procedures were performed during the study period. The flowchart depicts the final number included in the study ([Fig. 2]). The demographic data of the study group is presented in [Table 1]. The mean age of the patients was 49.6 ± 7 years (range: 10–95 years). Majority of the patients were males (80, 67.8%). Inability to swallow associated with head injury was the most common indication (43, 36.4%) followed by carcinoma esophagus (35, 29.8%) and stroke (24, 20.3%).

In carcinoma esophagus (n = 35), luminal dilatation with bougie was required in 25 (71.4%) patients prior to PEG placement. Fifty-six (48%) patients returned to oral feeding after radiotherapy and PEG tube was removed during the study period. Overall, 56 (48%) patients had removal of PEG tube that occurred between 12 weeks and 1 year of the placement. A total of 83 (71%) had comorbidities ([Table 1]). PEG-related complications were observed in 30 (25.4%) patients. The association of the complications with age, gender and the indication for PEG placement are described in [Table 2]. There was no PEG tube-related mortality.

PEG Site Identification and Fluoroscopy

The endoscopic transillumination, finger indentation, and safe needle track techniques were used for PEG site selection. Fluoroscopy was utilized in 38 (32.2%) patients of the total cases. In five cases, transillumination was not feasible due to thick abdominal wall. Ventriculoperitoneal shunt was present in 10 patients where fluoroscopy helped to map it out and avoid any accidental injury. In 15 cases of tube dislodgement and 8 cases of BBS, under fluoroscopy contrast injection with a cannula was used for assessing the previous tract patency and for PEG tube replacement ([Fig. 3]). In three cases of PEG site bleeding, the puncture was observed to be closer to the gastric wall. We assume that bleeding can be reduced if the puncture can be positioned away from the sides of stomach. The average dose of exposure in the use was 2–4 mSv (4–8 spot images) in intermittent fluoroscopy.

Tube Dislodgement

Tube dislodgement ([Fig. 4]) was the most common complication observed in 16 (13.5%) patients. Age > 60 years and dysphagia in neurologic disorders (DIN) were significantly associated with tube dislodgement (p-value = 0.001) ([Table 2]). All dislodgements occurred after 4 weeks of PEG placement. In 12 cases, a 16F or 18F Foley catheter was placed as a temporary measure by a trained staff at home. Later, reinsertion of PEG was done. In other four cases, the event occurred during the hospital stay and a new PEG tube was reinserted.

Aspiration Pneumonia

Aspiration pneumonia was noted in 15 (12.7%) patients with significant association with DIN (p-value = 0.028) ([Table 2]). They were managed conservatively using standard procedures.


#

Peristomal Infection)

A total of 13 (11%) cases had growth of organisms from PEG site (12 g—negative, 1 g—positive organisms). Ten cases had purulent secretion with sterile cultures and were not included in PSI. They were managed successfully with regular dressing. The positive isolates included Klebsiella,[6] Pseudomonas,[8] Acinetobacter, [1] and Staphylococcus aureus.[1] They were managed with antibiotics and regular dressing without removal of PEG tube. There were positive cultures from other sites: blood (n = 7), urine (n = 19), and tracheostomy catheter (n = 1). Two patients had recurrent PEG site infection and required multiple courses of antibiotics ([Fig. 5]). In none of the cases, the PEG site cultures matched with other site cultures, though they were done in the same admission.

Buried Bumper Syndrome

All the 15 (12.7%) cases of BBS presented with inability to feed or peristomal tightness. The urgent endoscopic assessment was done for suspected PEG tube malposition. PEG tube was removed by traction at the abdominal end and a new PEG tube was placed at the same site. Age > 60 years and DIN were significantly associated with both BBS and PSI (p-value = 0.001) ([Table 2]).


#

PEG Site Bleeding

Three patients presented with melena and peritubal bleeding in less than 7 days after PEG insertion ([Fig. 6]). One patient required blood transfusion. All the bleeding complications happened in hospital and were on combination of clopidogrel and aspirin. All the patients required tightening of external bumper and endoscopic injection of diluted adrenaline at the PEG site.[24]

Tube Obstruction

Tube obstruction was noted in five cases ([Fig. 5]). The PEG tube was cleaned with brush (Wilson Cook Medical GI Endoscopy,Cook, Ireland) and warm water, without the need for replacement.


#
#

PEG Tube Removal

PEG tube was removed in 56 (48%) patients on their recovery (between 12 weeks and 1 year after PEG insertion) either by external traction removal or under direct endoscopic vision by snaring the inner bumper and cutting loose the external bumper for the removal. Endoscopic removal was performed in 23 carcinoma esophagus cases that also enabled to assess the disease response to radiotherapy.


#

Survival

Forty-nine (42%) of the PEG patients expired due to either primary illness or due to sepsis ([Table 1]). Aspiration pneumonia was the cause of death in 12 (24.5%) of the patients. There was no mortality due to PEG tube procedure or PEG tube per se. There was no significant difference in median survival in patients having PEG-related complications (n = 30; 208 191–224 days) compared with those without (n = 88, 214 (28–233 days); (p = 0.740). The survival depended more on the primary disease than on the PEG-related complications ([Fig. 7]).

Discussion

PEG is cost-effective, minimally invasive method of establishing prolonged enteral feeding (> 4 weeks), hydration, and medication administration for patients unable to sustain oral intake.[25] [26] Adequate appropriate enteral nutrition can benefit critically ill patients by reducing complication rate and hospital stay.[27]

The most common indication for PEG tube placement is dysphagia secondary to cerebrovascular accident (CVA),[28] but in the present study, road traffic accident was the most common indication followed by carcinoma esophagus and CVA. This may be due to the referral pattern.

The technical success of PEG placement in the present study was 100%. The PEG placement was performed in endoscopy room with fluoroscopy facility (F-PEG). The fluoroscopy provided the advantage in accurate selection of the site of skin puncture.[29] In F-PEG, full gastric insufflation with carbon dioxide or use of water soluble contrast media delineates stomach outline and is helpful in altered upper GI anatomy.[15] [16] A cross-table lateral fluoroscopy image can identify colonic interposition between the stomach and abdominal wall.[30] Fluoroscopy-assisted colonoscopy can be used for moving transverse colon away from the anticipated PEG site in pseudo-obstruction (double-tube technique).[31] PEG site chosen in F-PEG at lower one-third of body of stomach equidistant from greater and lesser curvature lateral to rectus muscle can avoid injury to epigastric or gastroepiploic arteries and might reduce bleeding complications.[29] Placement of jejunal extension tubes (J-arm) through existing PEG tube can be performed with fluoroscopy that determines its exact position in the bowel (PEG-J).[32]

The adverse events after PEG in the literature range from 16 to 39%.[24] The most common post-PEG complication reported is inadvertent PEG tube removal or dislodgement due to pliability of inner bolster.[25] We suggest boxing hand wrap/use of abdominal binder for elderly patients and DIN to prevent tube dislodgement.[33]

BBS is an unusual complication with an estimated incidence ranging from 0.3 to 2.4%.[34]

In our series, BBS was noted in 12.7% and all of them underwent endoscopic replacement of PEG tube through the same site. BBS occurs due to inappropriate positioning of the gauge below the external bumper causing excessive pressure and tissue ischemia.[35] BBS could have been prevented by appropriate positioning of the PEG tube, leaving a small distance between the skin and the external fixator with daily rotation of the gastrostomy tube by 180 to 360 degrees.[18] BBS associated with PEG site bleeding can be prevented by releasing the tightened bumpers after 48 hours.[36] Clogged PEG tube is usually due to inadequate flushing with warm water before or after the PEG feed.[36]

In our study, PSI was noted in 11% with Klebsiella and Pseudomonas being the common organisms. In the study by Krishna et.al, PSI was noted in 24% with Pseudomonas being the most common organism.[23] The major determinants of PSI are antibiotic prophylaxis, PEG insertion techniques, wound care practices, and debilitated patients. This study suggests the organism and sensitivity pattern of PSI infection to guide the infection prevention and treatment strategy.[37] Of the PSI patients, eight patients had an infection in other sites.

A Cochrane systematic review showed pneumonia was significantly higher in patients with oropharyngeal dysphagia and favors PEG over NG in these patients. The occurrence of aspiration pneumonia depends on the cough reflex, volume and pH level of refluxed material, and the integrity of the immune system.[3] We observed that DIN had higher association with development of aspiration pneumonia. The 6-month mortality rate was 42%, which was equivalent to the earlier reported mortality rates of 1.5 to 54%.[38] [39]

The main strength of the study is availability and use of fluoroscopy during PEG procedure in unanticipated technically challenging situations; it may be difficult to transfer the sedated patient to a fluoroscopy room. The sample size was adequate with variety of indications and adverse events of PEG.

There are some drawbacks in the study. First, it being a retrospective single-center study has its inherent limitations. Second, aspiration pneumonia accounted for about one-fourth of mortality that is difficult to attribute as a complication of gastroesophageal reflux from feeds or due to underlying primary illness. Prospective multicenter studies with larger sample size will be required to validate our findings.

In conclusion, presence of fluoroscopy in the endoscopy theater will help in accurate PEG site (F-PEG) selection and placement. Age > 60 years and DIN were independent risk factors associated with tube dislodgement, PSI, and development of buried bumper. The survival after PEG placement depends more on the primary disease than on the PEG-related complications.
