What procedural step is involved in performing sigmoidopexy?

Sigmoidopexy is a surgical procedure primarily aimed at treating certain conditions such as sigmoid volvulus, where the sigmoid colon twists and obstructs its own blood supply or transportation of fecal matter. The key step in performing sigmoidopexy is the stabilization or fixation of the sigmoid colon to surrounding structures, which can help prevent recurrence of the volvulus.

In comparison to the other options, fixation to the rectal wall effectively addresses the problem of the twisted colon by anchoring it in a more stable position. The technique involves suturing the sigmoid colon to the rectal wall or nearby structures, which provides support and helps to maintain the colon's position post-operatively. This intervention does not involve reattaching the colon to the cecum, correcting malrotation, or removing any rectal segment, making fixation the critical procedural step.

Through this understanding, one can appreciate the specific goals of sigmoidopexy and how it is critical for addressing specific conditions involving the sigmoid colon.
