Mesh erosion into the rectum after laparoscopic posterior rectopexy: A case report

Area of Science:

• Gastroenterology
• Surgical Innovation
• Medical Device Complications

Background:

• Rectal prolapse is a condition often affecting elderly women.
• Mesh rectopexy offers a curative treatment for rectal prolapse.
• Mesh erosion is a significant risk associated with this procedure.

Purpose of the Study:

• To report a case of mesh erosion into the rectum following laparoscopic posterior rectopexy.
• To highlight the potential complications of synthetic mesh in rectal prolapse surgery.
• To emphasize preventive measures against mesh erosion.

Main Methods:

• A case study of a 78-year-old woman presenting with bloody stool 4 years post-laparoscopic posterior rectopexy.
• Diagnostic workup included colonoscopy and computed tomography.
• Surgical intervention involved mesh and tacker removal with rectal resection and permanent colostomy due to pre-existing fecal incontinence.

Main Results:

• Mesh erosion into the rectal lumen was confirmed.
• The mesh was found to have migrated and was protruding into the rectal lumen.
• The patient required a permanent colostomy due to severe fecal incontinence and decreased anal sphincter function.

Conclusions:

• Mesh erosion is linked to synthetic, non-absorbable mesh materials.
• Chronic irritation and friction from mesh shrinkage can contribute to erosion.
• Attention to mesh material and secure fixation is vital for preventing mesh erosion.
