Single-stapled Double Purse-string Technique for Colorectal Anastomosis

Single-stapled Double Purse-string Anastomotic (SIA) Technique in Robotic Malignant Sigmoid Resections

A single-arm, single-center prospective study of a novel double purse-string technique for constructing the colorectal anastomosis in robot-assisted laparoscopic resection of the sigmoid colon for cancer.

In all, 30 consecutive patients will be enrolled. The first 5 will be regarded as a pilot series for testing and aligning the study setup. The next 25 patients will form the study group. The clinical outcomes will be compared with historical control patients from our own department. Safety and feasibility will be assessed by short-term clinical outcomes.

Inclusion Criteria (all must be fulfilled):

• Verified cancer of the sigmoid colon
• Planned elective robot-assisted laparoscopic resection of sigmoid colon with primary anastomosis
• Operation with curative intent

Exclusion Criteria:

• Not legally competent and/or < 18 years old
• Not able to comprehend information and/or give written consent
