Overview
Definition:
Stoma siting is the precise marking of the abdominal wall for the creation of a surgical stoma (colostomy, ileostomy, urostomy) to facilitate fecal or urinary diversion
Comprehensive counseling involves educating the patient and their family about the stoma, its management, and its impact on their life, aiming to promote adaptation and improve quality of life.
Epidemiology:
The incidence of stoma formation varies widely depending on the underlying pathology, ranging from elective procedures for functional bowel disorders to emergency surgery for trauma or malignancy
Millions worldwide live with a stoma, highlighting the importance of expert siting and counseling.
Clinical Significance:
Proper stoma siting is paramount to prevent complications such as skin irritation, leakage, retracted stomas, or hernias, which can lead to significant morbidity and patient distress
Effective counseling empowers patients, reduces anxiety, and facilitates self-care, optimizing outcomes postoperatively.
Indications For Stoma
Colorectal Cancer:
Resection of rectal or colonic tumors requiring diversion
Low anterior resection syndrome prevention
Palliative fecal diversion.
Inflammatory Bowel Disease:
Severe ulcerative colitis or Crohn's disease requiring colectomy or proctocolectomy
Toxic megacolon management.
Diverticular Disease:
Complicated diverticulitis, such as perforation with peritonitis, abscess formation, or fistula requiring proximal diversion.
Obstruction:
Malignant or benign bowel obstruction unresponsive to conservative management
Temporary stoma to relieve distal obstruction.
Trauma:
Bowel perforation or resection due to abdominal trauma
Temporary stoma for fecal diversion following anastomotic repair.
Functional Bowel Disorders:
Intractable constipation or fecal incontinence in select cases, often as a last resort.
Stoma Siting Considerations
Patient Factors:
Patient's mobility and reach
Abdominal wall girth and contour
Presence of scars or previous surgery
Dominant hand for appliance management.
Anatomical Landmarks:
Identifying the rectus abdominis muscle bulges
Avoiding bony prominences (iliac crest, umbilicus, costal margin)
Ensuring adequate distance from the groin and beltline.
Appliance Fitting:
Considering the size and type of stoma appliance
Allowing sufficient space around the stoma for the adhesive barrier
Testing with a template if possible.
Lifestyle Factors:
Patient's occupation and hobbies
Clothing choices
Need for discretion
Potential for exposure to water or sand.
Surgeon Factors:
Surgeon's preference and experience
Ability to access the abdominal wall during surgery
Proximity to potential hernia sites.
Preoperative Counseling
Education On Stoma:
Explaining the type of stoma (colostomy/ileostomy/urostomy), its purpose, and expected output
Discussing the surgical procedure and recovery timeline
Showing visual aids or models.
Emotional Support:
Addressing patient's and family's fears, anxieties, and concerns about body image, intimacy, and social life
Encouraging questions and open communication.
Practical Aspects:
Demonstrating stoma appliances and explaining their function
Discussing diet and fluid management
Introducing the concept of stoma care nurses or support groups.
Involving Support System:
Encouraging family members or close friends to attend counseling sessions to provide additional support and understanding
Assigning a primary caregiver if needed.
Postoperative Care And Counseling
Immediate Postoperative Care:
Monitoring stoma viability, color, and output
Ensuring proper appliance fit
Pain management and fluid balance
Early mobilization.
Stoma Care Education:
Hands-on demonstration of pouch emptying, changing, and skin care
Teaching the patient and caregiver stoma care techniques in a step-by-step manner
Reinforcing hygiene practices.
Dietary And Fluid Management:
Guidance on gradual reintroduction of diet
Identifying foods that may cause gas, odor, or blockages
Emphasizing adequate hydration, especially for ileostomates.
Addressing Complications:
Educating on common complications like skin irritation, leakage, or changes in stoma output
Instructing on when to seek medical attention
Providing contact information for stoma nurses or surgeons.
Long Term Support:
Facilitating referrals to stoma care nurses for ongoing support
Connecting patients with ostomy support groups
Discussing psychological adaptation, sexuality, and travel adjustments.
Common Stoma Complications
Skin Irritation:
Caused by leakage, aggressive cleansing, or allergic reaction to appliance
Management involves proper appliance fit, skin barrier use, and appropriate cleansing agents.
Stoma Retraction:
The stoma recedes below skin level, leading to leakage and difficulty in appliance adherence
May require surgical revision.
Stoma Stenosis:
Narrowing of the stoma opening, impeding output
Can be due to scar tissue or inflammation
May require dilation or surgical revision.
Stoma Prolapse:
The bowel protrudes through the stoma opening, potentially leading to ischemia or trauma
Requires reduction, and sometimes surgical correction.
Parastomal Hernia:
Protrusion of abdominal contents through the fascial defect around the stoma
Management ranges from conservative to surgical repair.
Key Points
Exam Focus:
The ideal stoma site is within the rectus abdominis muscle, avoiding skin creases, bony prominences, and the beltline
Counseling should be holistic, addressing physical and psychosocial aspects
DNB/NEET SS expects knowledge of stoma types, siting principles, and complication management.
Clinical Pearls:
Always involve a stoma nurse in pre- and post-operative counseling
Use a marker pen to clearly delineate the stoma site on the patient's abdomen while they are in standing, sitting, and supine positions
Consider the patient's dominant hand for appliance management.
Common Mistakes:
Siting the stoma too close to bony prominences or skin folds
Inadequate preoperative counseling, leading to patient anxiety and poor adherence
Failing to address psychosocial impacts of living with a stoma.
