Cervical gastric decompression tube: safety and efficacy outcomes for inoperable malignant bowel obstruction

Abstract

Background: Inoperable malignant bowel obstruction, which results in chronic nausea, vomiting and abdominal pain, often requires nasogastric tube decompression. However, these tubes are often uncomfortable for patients and require hospitalization during the end-of-life care. Cervical esophago-gastric (CEG) decompression tubes are a potential palliative solution. The objective of this study is to present the outcomes of CEG tubes in 11 patients with malignant bowel obstruction.

Methods: We performed a retrospective review of patients requiring nasogastric tube decompression who received CEG decompression tubes for inoperable malignant bowel obstructions between 2016-2022. CEG tube placement was performed percutaneously through the left neck using a guidewire and an endoscopic technique.

Results: The average age of patients was 58 years (31-72 years), with metastatic colorectal cancer (36.4%) and ovarian cancer (27.3%) being the most common causes of malignant bowel obstruction. All procedures were completed percutaneously, without requiring conversion to open procedures. The morbidity of the procedure was 27%, which included tube dislodgement, local cellulitis, or bleeding at the insertion site. None of the patients required reoperation, with most of the patients successfully treated conservatively. Most patients were discharged home after the procedure (82%); however, 45% were readmitted (mostly due to abdominal pain). Most patients (73%) were able to continue additional chemotherapy after tube placement. The average survival from cancer diagnosis was approximately six months, whereas the average survival after the procedure was about four months. No mortalities occurred due to CEG tube placement.

Conclusions: A CEG decompression tube is safe for patients with malignant bowel obstruction. The procedure allows patients to undergo additional chemotherapy and be discharged home with a more comfortable tube.
