Abstract

Objective: To determine the cause and high-risk factors for the development of intestinal fistulas (IFs) after ultrasound-guided microwave ablation (MA) of abdominopelvic lesions, and to identify effective prophylactic and therapeutic actions.Methods: Clinical data were collected from patients with an IF after ultrasound-guided MA of abdominopelvic lesions in our hospital from January 1, 2010 to December 31, 2018. The cause, diagnosis, and treatment of IFs in these patients were analyzed.Results: Among 8,969 patients who underwent ultrasound-guided MA of abdominopelvic lesions, eight patients developed IF after MA, Seven patients were discharged after being cured and one died.Conclusion: Abdominopelvic lesions are close to the intestines, so histories of surgery, radiotherapy, and abdominopelvic infection are high-risk factors for IF development after MA of these lesions. Surgical treatment should be provided as soon as an IF is identified.

Highlights

Ultrasound-guided microwave ablation (MA) is a minimally invasive method that can result in rapid recovery, short hospital stay, and good tolerance to treatment [1]
We reviewed cases of Intestinal fistulas (IFs) after MA of abdominopelvic lesions in our hospital and analyzed the primary disease, history and site of IFs, as well as the diagnosis and treatment after IF development in these patients
We identified the high-risk factors as well as prophylactic and therapeutic measures for IFs

Summary

Introduction

Ultrasound-guided microwave ablation (MA) is a minimally invasive method that can result in rapid recovery, short hospital stay, and good tolerance to treatment [1]. Common complications of ultrasound-guided MA of abdominopelvic lesions include hemorrhage, secondary infection at the MA site, diaphragmatic injury, biliary fistulas, pneumothorax, hemopleura, and gastrointestinal injury [7]. We reviewed cases of IFs after MA of abdominopelvic lesions in our hospital and analyzed the primary disease, history and site of IFs, as well as the diagnosis and treatment after IF development in these patients. In this way, we identified the high-risk factors as well as prophylactic and therapeutic measures for IFs
