Introduction:
Transanal minimally invasive surgery (TAMIS) is a valuable surgical option for removal of rectal polyps and early rectal cancers. A potential complication of this technique is abdominal entry if the lesion is located above the peritoneal reflection. We present the first case series describing the use of a laparoscopic stapling device to remove a sessile lesion, and seal the resulting defect simultaneously with full thickness excision of the rectal lesion, avoiding abdominal entry.
Presentation of cases:
Five patients with rectal lesions between 8 and 14 cm from the anal verge are described in this case series. Each underwent a stapled-TAMIS procedure as the lesion was suspected to be above the peritoneal reflection. The goal specimen was achieved in each procedure.
Discussion:
This article demonstrates the feasibility of a novel technique to remove sessile polyps in the upper rectum using laparoscopic staplers trans-anally through the TAMIS port. More studies and long-term follow-up are needed to evaluate the oncologic outcomes including the recurrence rate for those lesions removed with a stapler.
Conclusion:
For rectal lesions suspected to be above the peritoneal reflection, a stapled resection through a TAMIS port could prove be a valuable addition to the standard excisional approach to TAMIS.
