Abnormal connection between two epithelial surfaces
Tenesmus
Sensation of needing to open bowels without being able to produce stools
Hemicolectomy
Removing portion of large intestine
Hartmann’s procedure (proctosigmoidectomy)
Removal of rectosigmoid colon with closure of anorectal stump and formation of colostomy
Anterior resection
Removalal of rectum
Whipple procedure (pancreaticoduodenectomy)
Removal of head of pancreas, duodenum, gallbladder and bile duct

2 caesarean section scars
- Pfannenstiel incision
- Joel-Cohen incision
Pfannenstiel incision
- Caesarean section
- Curved incision two fingers width above pubic symphysis
Joel-Cohen incision
- Caesarean section
- Straight incision that is slightly higher than Pfannestial incision
Laparoscopic surgery
Several 5-10mm incisions to allow cameras and instruments to be inserted into abdomen via port sites
Diathermy
Uses high-frequency electrical current to cut through tissues or to cauterise small blood vessels to stop bleeding
2 kinds of diathermy
Monopolar diathermy
Bipolar diathermy
Monopolar diathermy
- Used in small or large operations
- Diathermy probe used by surgeon producing electrical signal
- Grounding plate is placed uner leg or buttocks, so circuit formed
- At site causes localised burning and tissue damage, electrical signal spreads through body to grounding plate
Bipolar diathermy
- Instrument with 2 electrodes, current passes between the two and affects the tissues in area
- Used for microsurgery
- Useful to stop signal passing through rest of body, such as with pacemaker
2 main categories of sutures
- Absorbable
- Non-absorbable
2 examples of absorbable suture
- Vicryl
- Monocryl
3 examples non-abdorbable sutures
- Silk
- Nylon
- Polypropylene
How is the skin closed
- Subcutaneous tissues closed with absorbable sutures to prevent dead space where fluid or air can go
- Epidermis closed with various techniques
Techniques for closing epidermis
- Staples
- Interrupted sutures
- Mattress sutures
- Continuous sutures
- Subcuticular sutures
Staples
Rapid way of closing skin which need removed later
Interrupted sutures
Series of individual knots
Mattress sutures
Series of individual sutures that each go from one side of wound, under and out the other side, and then back again to original side
Continuous sutures
Single suture goes in and out along the wound in a spiral shape
Cubcuticular sutures
Single absorbable suture side to side just below the skin to pull the skin edges together
What are drains
Tubes left inside body to allow air and fluid to drain away
At what 3 stages is WHO surgical safety checklist carried out
- Before induction of anaesthesia
- Before first skin inscision
- Before patient leaves theatre
What does WHO surgical safety checklist include
- Checking essential factors such as
- Patient identity
- Allergies
- Operation
- Risk of bleeding
- Introduction of all team members
- Anticipated critical events
- Counting the number of sponges and needles to ensure nothing is left inside patient
