Chimney Stoma

Chimney stoma

A chimney stoma is a raised stoma in which the longer length of bowel is brought out and stitched to the skin in a position to project out like a chimney.

It can be created as:

• Colostomy of the large intestine (chimney colostomy).
• Ileostomy (small intestine) Chimney ileostomy

The benefits of a Chimney Stoma

• Minimizes fecal contact on surrounding skin.
• Weakened chances of premature stoma retraction.
• Enhanced regulation of effluent of infected fields.
• Less strenuous wound treatment in dirty abdomen.
• Applicable as a temporary, damage-control stoma.

Chimney stoma surgery

Chimney stoma surgery is an extraordinary procedure of making a stoma (artificial bowel opening), whereinby the bowel is protruded and held in a tube-like chimney-like shape above the skin. This design allows minimizing skin complications and simplifying the process of stoma care in challenging clinical scenarios.

What is the Rationale behind Chimney Stoma Surgery?

This method is selected because a standard flat stoma has a high risk of complications, including:

• Severe abdominal wall infection/contamination.
• Bowel perforation or peritonitis.
• Edematous or friable bowel or unhealthy bowel.
• Large risk of stoma retraction (obesity, malnutrition, steroid use)
• Emergency surgeries
• Weak tissues among the pediatrics.
• Temporary fecal diversion in severely-ill patients.

Chimney stoma procedure

The chimney stoma is an expert procedure of forming a temporary stoma in the form of a long, protruding chimney-like tube instead of maturing the bowel out of the skin. It is usually applied during emergency, contaminated or high-risk surgery.

Pre-operative Preparation

• Stabilization of the patient (fluids, antibiotics, electrolytes)
• Stoma site marking (in case there is time) - in emergencies, the stoma site is usually not known.
• In contaminated cases, broad-spectrum antibiotics.
• Introduction of nasogastric and urinary catheters (when necessary)

Chimney Stoma Procedure

Abdominal Access

• Appeared through laparotomy or laparoscopic means.
• First dealt with primary pathology (perforation, obstruction, sepsis, etc.).

Selection of Bowel Segment

• Well-vascular bowel is selected which is healthy.

May be:

• Ileum → chimney ileostomy
• Colon → chimney colostomy

Creation of Stoma Opening

• A minor round opening is cut in the pre-stomal site of choice.
• Layers of the abdominal wall (skin -subcutaneous tissue -fascia -muscle -peritoneum) are incised with caution.
• It is opened just tight enough not to be slipped back again.

Bowel Exteriorization 

• A piece of bowel (6-10 cm or more) is pulled out, which is longer than usual.
• No eversion or formal maturation is made at once.
• Bowel is still edematous and cylindrical to create the chimney.

Fixation to the Skin

• Seromuscular sutures attach bowel to skin.
• Sutures allow no retraction and flatten not the stoma.
• At the top of the chimney the bowel lumen opens.

Assessment of Viability

• Peristalsis, color and bleeding are monitored.
• Any indication of ischemia must be revised.

Appliance Placement

• Stoma bag applied carefully
• The initial requirement may be larger or flexible appliances on the basis of edema.

Post-operative Management

Monitor:

• Stoma color and edema
• Production quantity and stability.
• Fluid and electrolyte balance.
• Involvement of the stoma nurses at an early stage.
• Edema is slowly resolved, stoma being also narrowed with time.

Futures and Future Management

• Normally designed as a temporary stoma.

Options later:

• Stoma reversal
• Turned to a normal matured stoma.
• Timing is based on patient recovery and sepsis/inflammation recovery.

Chimney stoma complications

Chimney stoma is safe and may be used in situations of high risk or emergency, as well as any other stoma, may cause an early and late complication. There are those that are associated with the protruding or chimney design and others that are common with each and every stoma.

Early Complications (First Days–Weeks)

• Stoma Edema
• Stoma Ischemia / Necrosis
• Mucosal Bleeding
• Retraction (Uncommon)
• High Output (Especially Ileostomy)

Late Complications (Weeks–Months)

• Stoma Prolapse
• Skin Irritation (Peristomal Dermatitis)
• Appliance Fitting Difficulties
• Parastomal Hernia
• Stoma Stenosis (Rare)

Conclusion

Chimney stoma is a useful and sometimes life-saving surgery especially when patients are in emergencies, abdominal contamination, and when cases are high-risk. It makes postoperative care safer and easier by exteriorizing the bowel in a bulbous, or protruding, chimney-like manner, thereby greatly decreasing the possible early complications, which are retraction and mutilation of the skin, which can be severe. Whereas complication such as edema, bleeding, prolapse, or problems with the appliances may arise, the majority of them are both temporary and treatable with proper monitoring, good stoma care, and early intervention. Notably, the chimney stomas are normally meant to be temporary solutions, and they are supposed to be reversed or converted to a matured stoma after the state of the patient has stabilized. On the whole chimney stoma surgery is efficient in providing fecal diversion with increased safety in difficult surgical cases leading to the enhancement of patient outcomes and recovery.

FAQ

1. Is a chimney stoma permanent?

• No. The majority of chimney stomas are provisional. They are normally turned or changed into a standard matured stoma after a patient recovers and the inflammation had died.

2. Is the care of chimney stoma challenging?

• Not usually. Care is more convenient than a flat stoma in most of the cases since the protrusive nature minimises leakage onto the surrounding skin. The preliminary equipping of appliances might have to be readjusted because of edema.

3. What duration of a chimney stoma is swollen?

• Stoma edema occurs frequently and normally subsides after 1-2 weeks following surgery when the inflammation subsides.

4. Is it safe to reverse chimney stoma?

• Yes. When the underlying disease is well treated, the patient is nutritionally and medically stable, and then reversal is pretty safe and successful.

5. Can children have chimney stoma?

• Yes. Chimney stomas are widely employed in emergency surgical operations involving the neonatal and pediatric surgical units, particularly in the cases with sensitive tissues, and high chances of infection.

6. What is the difference between chimney stoma and loop stoma?

• A chimney stoma is longer and not completely developed initially whereas a loop stoma is shorter and is normally developed at a skin level. Chimney stomas are predominately damage-control stomas.

7. Who ought to be in charge of chimney stoma?

• It should be taken care of with the assistance of a trained stoma nurse, surgeon, and health care team to avoid the complications and organize the timely reversal.
