Stoma examination (by Dr Ikhwan Sani)
    1. Stoma examination
         ● Part of abdominal examination
          ● Position: supine position
          ● Exposure: supposed to be from nipple to knee, but for patient’s
           modesty, I expose from xiphisternum to pubic symphysis
          ● Inspection (bag → content → stoma → skin)
                ● Drainage bag located at left lower quadrant of the abdomen
                ● The drainage bag is transparent and I can see a stoma behind
                   the drainage bag
                      ● The drainage bag is not transparent so I could not know
                         the content. Will confirm by palpation later
                 ● Content of drainage consists of faecal matter which is semi-solid
                      ● Yellowish effluent usually for ileostomy
                      ● Semi-solid faeces for colostomy
                       ● Stoma bag is distended with gas & vapour is seen
                ● And I can see a single lumen stoma on my inspection
                 ● The stoma is created flush with the skin (flat and even with
                   the skin)
                      ● Presence of a spout or flush with the skin
                       ● Spout = ileostomy
                       ● Stoma flush with the skin = colostomy
                ● Stoma looks healthy, pink, dark=gangrene, pale=ischemia
                 ● No prolapse, no retraction of stoma
                ● No bleeding point
                ● No skin excoriation seen around the stoma
                 ● No scar on the abdomen
         ● Wear gloves, prepare gauze and yellow bag, open the drainage bag
         ● After I opened the bag,
                ● Content of drainage bag
                 ● I see a single lumen stoma created flushed to the skin
                ● Stoma looks healthy, pink, no gangrene
                 ● No bleeding point
                 ● No skin excoriation seen around the stoma
          ● Ask patient to cough
                ● Look for parastomal hernia
                ● 2 types of parastomal hernia: revealed and concealed
                 ● Revealed hernia is protruded even without coughing
                ● Concealed hernia is expulsion seen on coughing
          ● Palpation
               ● (from outside to inside - less contaminate the skin with stoma
                  content)
                ● Pak cik ade rase sakit mane mane?
               ● Palpate the skin around the stoma with two fingers for
                   tenderness (infection parastomal abscess)
                  ● Palpate the stoma to see contact bleeding
                   ● Put gel and insert little fingers into the lumen to confirm whether
                     is a single or double lumen stoma
                        ● If 2 lumen try to separate them
                         ● If cannot be separated, it is a loop stoma
                         ● if able to be separated, it is a double barrel stoma
                        ● Any stenosis
         ● Auscultation
               ● For bowel sound on the abdomen as the evident of functioning
                  stoma (+ drainage bag content)
         ● Complete the examination with
               ● Digital rectal examination
                    ● If end colostomy for post-APR: absence of anus
                    ● If Hartmann procedure: anus still patent
                     ● If paediatric patient: assess anal tone (Hirschsprung
                        disease) and anal patency (imperforate anus)
               ● Look at urine I/O chart, BUSE
                     ● To detect fluid electrolyte imbalance
    2. What is a stoma?
        ● Stoma is a surgically created opening that connects a hollow organ to
            another hollow organ or a hollow organ to the external environment
   3. Not only for drainage and diverting, stoma can also be an input port eg
      feeding jejunostomy and tracheostomy
   4. How to classify stoma?
        ● According to the location (stoma is created on a mobile part of the
             bowel)
                 ● Left lower quadrant - sigmoid colostomy
                  ● Right upper quadrant - proximal transverse colostomy
                  ● Right lower quadrant - cecostomy (rarely done nowadays due to
                   high complication such as perforation)
                  ● Right lumbar or iliac fossa - ileostomy
         ● According to design
                ● End colostomy
               ● Double barrel colostomy
               ● Loop colostomy
         ● Based on function
               ● Temporary
                     ● Double barrel colostomy
                    ● Loop colostomy
                   ● Permanent
                       ● Usually end colostomy
   5. Cecum, transverse colon and sigmoid colon are mobile so suitable to have
       stoma
          ● Ascending and descending colon are not suitable because they are
            fixed to the posterior abdominal wall by lateral peritoneal fold /
             paracolic gutter / Todt fascia
   6. If a stoma located at left iliac fossa, but spouting of mucosa, with a laparotomy
       scar?
          ● Think ileostomy! Because patient may have adhesions
              post-laparotomy, causing difficulty to bring out and create the ileostomy
               on RIF, thus mobilise the bowel and do it on LIF
   7. Why is transverse colostomy done in the Right hypochondriac region?
         ● Colostomy is anchoring by hepatic flexure
        ● Can prevent stoma prolapse
        ● Less impact of peristaltic movement as the distance from stoma to the
             flexure is short
        ● The longer the distance, the higher risk of stoma prolapse
    8. Criteria of location to bring out the stoma
          ● Able to be seen and easily accessible by patient especially in obese
               patient - mark stoma site on patient lying and standing
                    ● Unless nephrostomy at the back
          ● Away from bony prominence - ASIS
           ● Away from waist line or belt area in male
          ● Avoid skin crease
          ● Avoid surgical scar - risk of wound contamination + infection
           ● Away from old surgical scars - risk of hernia
          ● Must have enough bowel mobilisation - to prevent tension over the
              stoma which leads to decreased vascularity and finally stoma necrosis
   9. Indicators of a functioning stoma
          ● Abdomen not distended - no intestinal obstruction
          ● Presence of vapour / distended with gas
         ● Content drained out into the bag
          ● Bowel sound present
   10. Indications of stoma
           ● Temporary
                   ● Emergency procedure (Eg: Hartmann’s procedure done in the
                     case of Rectosigmoid Ca presented with intestinal obstruction)
                  ● Defunctioning a distal anastomosis aka Covering stoma (Eg:
                    Trephine transverse loop colostomy done after left
                     hemicolectomy+primary end to end anastomosis in the case of
                    colorectal Ca)
                   ● Defunctioning an inflamed sigmoid in diverticular disease /
                    Crohn disease (Eg: Trephine transverse loop colostomy)
A loop of colon is brought to the surface of the body and may be supported by a rod
which is removed after about 5 days. The bowel wall is partially cut to produce 2
 openings (afferent and efferent limb). The afferent limb leads to functioning part of
the colon (which stool and gas pass out) and the efferent limb leads to
 non-functioning part of the colon.
                  ● Defunctioning the rectum or anus (Eg: Loop sigmoid colostomy
                     was currently done in the case of rectal cancer/
                    incontinence/perianal abscess/pelvic fracture)
                   ● Diversion (Eg: in acute IO due to advanced rectal Ca, trephine
                    sigmoid colostomy done to divert faeces and relief bowel
                    obstruction, then arrange patient for radiotherapy to shrink
                     tumours, then only subject patient for surgery)
**Trephine colostomy is a type of loop colostomy without laparoscopy or open
 laparotomy. It is a minimally invasive procedure done only in emergency situations.
Commonly created as proximal trephine transverse colostomy or trephine sigmoid
 colostomy.
**Ileo-colic anastomosis usually won’t need covering stoma because small bowel
 has rich blood supply → faster healing → less risk of anastomotic risk. However,
anastomosis btw large bowel usually needs covering stoma because large bowel
has poor blood supply.
          ● Permanent
               ● End colostomy (after Abdominal Perineal Resection follows
                  rectal Ca or anal Ca)
               ● End Ileostomy (after panproctocolectomy follows Familial
                 Adenomatous Polyposis)
   11. Common causes of stoma
          ● Paediatrics: (All are temporary)
                 ● Hirschsprung disease
                     ● Short segment rectosigmoid 80%
                      ● Long segment 10%
                      ● Total colonic 5%
                     ● Total colonic with small bowel involvement 2%
                 ● Necrotizing enterocolitis
                ● Imperforate anus
                ● Anorectal swelling - trauma
                      ● Worry of soiling - diversion to promote healing
                ● TB colitis lead to TB peritonitis as anastomosis cannot be done
                  immediately
         ● Adult
                ● Hartmann procedure
                 ● IO to divert faeces
                ● Covering stoma to rest bowel after dissection (defunctioning)
                 ● Perineal injury - perianal abscess, severe pelvic fractures
                  ● Permanent stoma
                        ● APR
                        ● Rehabilitation patient
                       ● Advanced ca
                        ● Immobilize patient
   12. Complications of stoma
          ● Early complication
                  ● Stoma gangrene
                       ● due to poor blood supply
                   ● Parastomal abscess
                  ● Stenosed stoma
                       ● Due to inadequate cutting on the rectus sheath
                   ● Skin excoriation due to digestive enzyme
                       ● Treat with zinc oxide and frequent dressing
         ● Late complication
                ● Prolapsed stoma (> 4cm protrusion from skin)
                 ● Retracted stoma
                ● Parastomal hernia
                ● Disuse atrophy of distal part of stoma
                      ● Distal lumen became smaller
                     ● Due to faecal diversion
    13. Presence of midline laparotomy scar + single lumen stoma, how to
       differentiate it is a Hartmann procedure or abdominal perineal resection?
            ● Inspect the anus
                     ● Closed anus → Abdominoperineal excision
                    ● Patent anus → Hartmann
    14. In bowel resection, when can we anastomose immediately without a
       defunctioning stoma?
            ● For colocolic anastomosis, a covering/defunctioning stoma is done
                   ● As blood supply in large intestine is not as good as in small
                     intestine
                    ● So give time for healing
                   ● Loopogram done to look at anastomotic site
                         ● See any stricture
                    ● If healthy, then can close back / reverse the stoma
         ● For ileocolic anastomosis, then no need a covering stoma
