Neural block therapy for radiation enteritis: a case report.

BACKGROUND

Radiation enteritis following radiotherapy targeting the abdomen occasionally causes ulcers or ileus, which can be difficult to treat and usually progressive and refractory, significantly degrading the patient's quality of life.

CASE PRESENTATION: A 58-year-old woman had undergone surgery for cervical cancer approximately 21 years ago. During treatment, she had also received radiotherapy targeting the pelvis and stomach. She presented with complaints of vomiting and lower abdominal pain and was subsequently diagnosed with multiple gastric ulcers, enterocolitis, and paralytic ileus due to late radiation-induced sequelae. We reasoned that visceral sympathetic block would improve the abdominal symptoms; therefore, we performed a splanchnic nerve block and an inferior mesenteric artery plexus block. As predicted, these block procedures improved the symptoms.

CONCLUSIONS

Radiation enteritis is an iatrogenic disease, and there is no established treatment for intractable cases. However, visceral sympathetic nerve block may show efficacy as a potential therapy for radiation enteritis-associated abdominal pain and ileus.
