Radiation enteritis following radiotherapy for prostatic carcinoma

Area of Science:

• Oncology
• Radiation Oncology
• Gastroenterology

Background:

• Supervoltage radiation therapy is a common treatment for prostate cancer.
• Radiation enteritis and small bowel obstruction are known complications.
• The small bowel's sensitivity to radiation can be influenced by surgical procedures.

Purpose of the Study:

• To report two cases of radiation enteritis and small bowel obstruction after prostate cancer radiation therapy.
• To discuss the mechanisms and contributing factors of radiation injury to the small bowel.
• To propose a modification in surgical procedures to minimize radiation-induced small bowel damage.

Main Methods:

• Case report analysis of two patients.
• Review of literature on radiation injury mechanisms.
• Discussion of surgical approaches for lymph node staging.

Main Results:

• Two patients developed radiation enteritis and small bowel obstruction post-treatment.
• Transperitoneal procedures may increase small bowel sensitivity to radiation.
• Extraperitoneal lymph node staging is suggested as a preventative measure.

Conclusions:

• Radiation enteritis and small bowel obstruction are significant risks following prostate cancer radiation.
• Surgical technique for lymph node staging can impact radiation injury.
• Extraperitoneal lymph node dissection may mitigate radiation-induced small bowel complications.
