How convex ostomy bags should be to ensure the avoidance of leaks & irritation

The purpose of a convex colostomy, ileostomy or ureterostomy bag is to ensure perfect fit of the base to the skin to prevent leaks, one of the most common challenges in the care of any ostomy.

• He should apply sufficient pressure around the stoma to smooth out the peristomal contour, especially the folds and creases of the skin, to ensure that the base of the pouch has perfect contact with the skin.
• At the same time, he should apply the right amount of pressure to the skin around the stoma, to allow it to protrude as much as possible into the pouch. This improves the drainage of waste into the pouch and is extremely useful for flat stomas as well as those that are retracted .
• He should not apply prolonged pressure that could damage the stoma and surrounding skin.
• It should be flexible enough to adhere and conform perfectly to the shape of the body, especially when the patient tries to move or change position.
• It should make accessories such as colostomy bag rings unnecessary.
• It should be comfortable.

Curved stoma systems are suitable for:

• Stomata that are flat or retracted, especially when the stoma secretions are quite “wet”.
• When the stoma outline shows skin folds, wrinkles, scars, channels or there is significant abdominal relaxation
• When the stoma is in an unfavorable position, e.g. it tilts downwards or is at the level of the skin
• In loop orifices, where there is a loop with two orifices.
• In the case of prolapse
• In stomas with high amounts of secretions or very liquid secretions to increase the life of the bag. Liquids penetrate the “gaps” that the skin may have much more easily than formed feces

If you suffer from ostomy leaks , your doctor will usually prescribe a convex ostomy pouch. However, their decision is based on an assessment of both the nature of the ostomy and the patient's abdomen and its contours.

Such an assessment is necessary and particularly important in the early postoperative period since it is not limited only to determining the correct size of the bag but the patient is assessed in different positions such as lying down, sitting and standing.

Ultimately, of course, those living with permanent stomas decide for themselves which pouch they use, however, regular re-evaluation by a doctor is always recommended, as inappropriate use of a curved pouch can lead to complications.

B Braun ostomy bags provide all the features described above and are available in one- and two-piece systems for all types of stomas.

• Base that acts as a skin protector with moderate curvature
• 4mm deep curvature
• Gentle slope for good pressure distribution
• For retractable spouts
• Three slots on each side of the protective ring for a fastening belt that allow the patient to wear the bag at an angle

• Base with moderate curvature
• 6mm deep curvature with a gentle slope
• Curved design for good pressure distribution
• Guided coupling system for precise, simple and safe positioning of the bag on the base
• For retractable spouts
• Three slots on each side of the protective ring for a fastening belt that allow the patient to wear the bag at an angle
