Introduction Chronic gastrointestinal obstruction can precipitate a constellation of symptoms including nausea, vomiting, abdominal distension and pain that negatively impact on health-related quality of life. Decompression via venting gastrostomy can offer symptomatic relief but safety and efficacy data are sparse. This study characterises the diverse venting percutaneous endoscopic gastrostomy (vPEG) cohort at our tertiary referral centre and defines the safety and efficacy of this procedure.
Methods Patients undergoing vPEG between May 2012 and June 2020 were identified from a prospectively maintained database and demographic, procedure-related and mortality data were extracted. Retrospective analysis of case notes provided data on patient symptoms. Last follow-up was May 2021.
Results 27 patients (median age 63, range 18–90 years) underwent vPEG insertion. The majority of vPEGs were for patients with obstruction secondary to locally advanced or metastatic malignancy (n=21/27, 77.8%). Six procedures were performed for benign disease (n=6/27, 22.2%). No patients developed the recognised serious complications of bleeding, perforation or peritonitis from vPEG insertion. Symptoms of nausea (p=0.006), vomiting (p<0.001), abdominal distension (p<0.001) and abdominal pain (p=0.002) were improved following vPEG. Pain beyond the expected postprocedural discomfort was associated with a lower number of days survived postprocedure (p=0.026).
Conclusion vPEG can be a safe and efficacious palliative intervention for benign and malignant chronic gastrointestinal obstruction. Severe postprocedural pain should be promptly investigated to exclude a potential complication. A defined clinical strategy for assessing and managing these patients would facilitate wider recognition of the benefits of vPEG and improve the safety profile in centres with more limited experience.
