Marking a Stoma on a BMI 39 Abdomen: The Mark That Works Only When Lying Down

The existing mark is unsafe, for one decisive reason: it was placed with the patient in a single position.

A stoma site must be assessed in supine, seated, and standing positions. This mark disappears under the pannus when he sits. A stoma brought out through or beneath a pannus will:

• be difficult or impossible to see and pouch, especially for a patient who will be doing this himself;
• retract as the pannus moves and hangs;
• leak continuously, because a pouch cannot maintain a seal on skin that folds and falls away;
• carry a higher risk of parastomal hernia and of skin breakdown.

Assessment sequence before placing a mark:

1. Observe standing, seated, and supine, with the abdomen relaxed and then tensed (ask him to lift his head and shoulders to engage the rectus).
2. Identify the rectus abdominis borders and mark within them - a stoma through the rectus has lower hernia risk.
3. Map no-go zones: umbilicus, all scars, skin folds and creases, the pannus edge and undersurface, bony prominences (ASIS, costal margin), the belt line, and the tool-belt line.
4. Confirm he can see and reach the site - and that he can do so while wearing his usual clothing and belt.
5. Ask about his work: lifting, bending, belt wear, and where a pouch would be crushed or sheared.
6. Check the skin itself - field changes from prior chemoradiation, and any existing dermatologic disease.
7. Document and photograph the chosen site and a backup site, and communicate directly with the operating surgeon the day of surgery.

Mark above the pannus, within the rectus, off the belt line.

• Height: the site should sit on the flat, stable abdominal wall that remains flat in all three positions. On a BMI 39 abdomen with a large overhanging pannus, that frequently means moving superiorly - toward the right upper quadrant or high right lower quadrant - rather than the textbook RLQ position. The textbook quadrant is a starting point, not a mandate; a pouching surface that stays flat beats an anatomically conventional site that retracts under a fold.
• Within the rectus sheath to reduce parastomal hernia risk, which is already elevated by obesity, midline incisions, and his lifting job.
• Off the tool belt and trouser waistband: a belt that crosses the stoma every working day will shear the seal, and in a lifting worker it will also press on the stoma. Identify his actual belt line with the belt on, not by estimating.
• Away from all three midline scars - scar tissue does not hold a barrier well and may tether.
• Mark a second, backup site and label both. Intraoperative findings - adhesions, the mesentery's reach, tension, the extent of resection - can invalidate the first choice. If the surgeon must move the stoma, the backup tells them where it can safely go.
• Verify the final mark seated and standing, with his shirt on and off, and have him look at it and reach it. A mark the patient cannot see or reach is a mark for the nurse, not for the patient.

This plan trades a conventional location for a durable, self-manageable one - which is the correct trade in a patient with this body habitus and this job.

Preoperative teaching and preparation:

• Acknowledge and reframe his "just get it over with." Avoidance is normal before cancer surgery and is a reason to teach in short, concrete increments, not a reason to skip preparation. Preoperative education reliably reduces postoperative anxiety and improves early self-care.
• Show him a pouch and a stoma model. Describe what the stoma will look like immediately after surgery - red, moist, swollen - so that the expected does not become terrifying.
• Set the timeline: the stoma will shrink over roughly 6–8 weeks; the initial system will be cut-to-fit and re-measured; independence usually comes in weeks, not days.
• Skill preview: emptying, changing, and what he can delegate early on.
• Anticipatory guidance: gas and odor are normal and manageable; diet advances gradually; he should chew well and add fiber slowly.
• Resources: a peer visitor or support group before surgery if he will accept one, and the name and number of the ostomy nurse.
• Screening: body image concerns, prior coping, depression risk, and social support at home.

Return to work and lifting:

• Avoid lifting more than roughly 10 lb (about 5 kg) for 6 weeks, then progressive increase, because of parastomal hernia risk. With his obesity and midline incisions, his risk is already high.
• No heavy crates or repetitive straining until cleared by the surgeon - which may mean modified duty when he returns.
• The tool belt has to be reconsidered: either it stays off the stoma or he chooses a different carry arrangement.
• Give these instructions in writing, and confirm with teach-back that he can state the lifting limit and the hernia warning signs (bulge, pain, change in stoma output).

Coordinate: the mark is only useful if the operating surgeon sees and honors it. Communicate directly, document the position and the backup, and photograph it.
