Aims:
This study aimed to describe the short-term perineal healing rates in patients with perineal reconstruction using a biological mesh following extralevator abdominoperineal excision (elAPE).
Methods:
In a retrospective, descriptive single-centre cohort study, 88 consecutive patients treated with elAPE and perineal closure using a biological mesh between January 2011 and December 2015 were reviewed. All available data from electronic hospital records was collected. Patients were followed for 1 year following surgery and perineal wound status assessed at 3 months and at 1 year.
Results:
In total, 63 patients were male and all but 8 patients were treated for primary rectal cancer. All patients but 3 had received radiotherapy prior to surgery. Multivisceral excisions were performed in 19 patients. Omentoplasty was performed in 55 patients and 3 different types of meshes were used during the study period. At 3 months, 58 patients (66%) had a healed perineum. No association was detected between patient, tumour or perioperative characteristics and perineal wound status at 3 months. At 1 year, 4 patients were deceased and among the remaining 84, the perineal wound was healed in 77 patients (92%).
Conclusion:
The use of biological meshes in perineal reconstruction following elAPE is feasible and safe, and the perineal wound is healed in the majority of the patients within 3 months.

Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...
Mesh Analysis with Current Sources
Current Source in One Mesh: The analysis process is straightforward when a current source is found in only one mesh within the circuit. Mesh currents are assigned as usual, with the mesh containing the current source excluded from the analysis. Kirchhoff's voltage law...
