Introduction

Hemipelvectomy is the removal of part of the pelvis and has been indicated in the surgical treatment of bone tumors and even soft tissues in humans and animals, and of constipation and poor union fractures of the pelvis.

Objectives

Surgical treatment for resolution of secondary constipation frame to stenosis of the pelvic canal after complication of bilateral ilium osteosynthesis.

Methods

A three-year-old mongrel, neutered male canine diagnosed with megacolon and fecal impaction due to a pelvic distress caused by a complication of left ilium body osteosynthesis, underwent partial hemipelvectomy surgery on the same side. After the removal of the implants of both bone fragments, an ileum osteotomy was performed cranial to the acetabulum, followed by dilatation of adjacent soft tissue and osteotomy of the pubis lateral to the pubis symphysis, until complete releasing of the bone fragment.

Results

Stenosis of the pelvic canal resulted in rectum compression that prevented the passage of stool by the site; the impossibility of defecation led to the formation of fecal impaction and megacolon. The left part hemipelvectomy, which was performed, made defecation possible because it removed the mechanical component of the pelvic canal stenosis, so that the passage of fecal contents through the intestine did not find any barrier in the pelvis.

Conclusions

The partial hemipelvectomy technique used for the treatment of constipation caused by pelvic canal stenosis was effective, providing normal defecation for the patient and absence of pain during defecation.
