Laparoscopic Proctocolectomy With Transanal Total Mesorectal Excision for Ulcerative Colitis

Area of Science:

• Colorectal Surgery
• Minimally Invasive Surgery
• Gastroenterology

Background:

• Transanal total mesorectal excision (TaTME) is an endoscopic retrograde technique for rectal cancer surgery.
• It is indicated for challenging transabdominal approaches and ensures clear resection margins.
• Ulcerative colitis carries a risk of dysplasia and cancer, necessitating surgical intervention.

Observation:

• A case report details the use of TaTME in a 38-year-old woman with ulcerative colitis and rectal dysplasia.
• The patient underwent laparoscopic proctocolectomy with TaTME performed simultaneously by two surgical teams.
• This approach was chosen due to suspected cancerous changes in the rectum.

Findings:

• The simultaneous two-team laparoscopic proctocolectomy with TaTME was successfully completed.
• The procedure resulted in a shorter operation time compared to traditional methods.
• The patient recovered well with no complications and preserved anal sphincter function.

Implications:

• Laparoscopic proctocolectomy with simultaneous two-team TaTME is proposed as a safe and effective surgical option for ulcerative colitis.
• TaTME facilitates accurate dissection and improved surgical manipulation in this context.
• This technique expands the application of TaTME beyond rectal cancer surgery.
