Abstract:

Objective

To evaluate the incidence, corresponding surgical risks, and prognosis of parastomal hernia after abdominal and perineal resection for rectal cancer under different intervention methods during surgery.

Methods

A total of 56 patients who underwent Miles surgery for rectal cancer in the Department of General Surgery, Beijing Luhe Hospital Affiliated to Capital Medical University from January 2014 to December 2018 were included. After preoperative discussions between doctors and patients, patients were divided into control group (no preset mesh, n=32) and experimental group (preset mesh, n=24) based on different surgical methods. In the experimental group, artificial mesh was placed under the sheath of the rectus abdominis, while in the control group, sigmoid colostomy was routinely performed. The incidence of parastomal hernia, short and long term surgery-related risks were observed at a follow-up of ≥6 months.

Results

After 5 years of follow-up (some cases died or lost contact), the overall incidence of parastomal hernia in the experimental group was 41.70%, which was lower than that in the control group (71.90%), (P=0.045). The incidence of H2 type parastomal hernia was 12.50% versus 43.75%, with statistical significant difference (P=0.026). The postoperative occurrence time of parastomal hernia in the experimental group was significantly later than that in the control group (48 months vs 10 months; P<0.001). In terms of safety, there was no significant difference in postoperative complications such as stoma infection, subcutaneous effusion, stoma stenosis, stoma prolapse, intestinal obstruction, and intestinal leakage between the two groups (P=0.798). But after long-term observation, we found that the preset mesh group has an increased risk of acute incarcerated parastomal hernia (H2 type).

Conclusion

Prophylactic mesh placement significantly reduces the incidence of postoperative parastomal hernia and significantly delays its appearance, and dose not increase short term surgical complications. However, the long-term risks are worth paying attention to.
