Resect the tumour area
Mobilise stomach into chest
Anastomose the distal oesophagus to stomach
Describe the post-op care for oesophagectomy
Diet: clear liquid -> liquid -> soft food -> normal diet
Jejunostomy tube until eating normally eg. 4-6 weeks
Describe the complications of oesophagectomy
Surgical: bleeding, recurrent laryngeal nerve damage
Anaesthetic
Short term post-op: pain, wound infection, DVT, anastomotic leak

- Abscess
Describe the complications of splenectomy
Intra-operative: bleeding, damage to surrounding structures
Anaesthetic
Short term post-op: pain, wound infection/dehiscence, DVT
Long term post-op: adhesions, infections (encapsulated bacteria)
Describe the indications for Whipple’s procedure
Pancreatic lesions: cancer, cysts
Cholangiocarcinoma
Describe the process of a Whipple’s procedure (briefly)
Open surgery (Chevron, midline)
- Dissect + move pancreas
- Remove the antrum to duodenum + head of pancreas + GB
- Anastomose stomach and jejunum
- Attach pancreas to free end of jejunum
Describe the complications of a Whipple’s procedure
Intra-operative: bleeding, damage to surrounding structures
Anaesthetic
Short term post-op: wound infection, bile leak, DVT, pancreatitis
Long term post-op: DM, recurrence, delayed gastric emptying
Describe the complications of rectal prolapse repair
Intra-operative: bleeding, damage to surrounding structures
Anaesthetic
Short term post-op: wound infection, DVT, pain, bowel obstruction
Long term post-op: recurrence, fistula, sexual dysfunction, mesh complications
Describe the process of rectal prolapse repair
Can be open/lap abdominal approach (rectopexy) or perineal
Abdo: use sutures/mesh sling to attach rectum to sacrum
Delorme: shorten rectum by removing mucosa
Altemeier: resect rectum segment + anastomose to sigmoid colon
Describe the pros and cons of open vs laparoscopic abdominal surgery
Open:
- Pros: better exposure, allows full resection/removal of large structures
- Cons: longer recovery time, higher rate of complications (wound infection, pain, bleeding)
Laparoscopic:
- Pros: smaller scars, decreased risk of complications, shorter recovery
- Cons: may not be practical (eg. inserting large stents), reduced visibility, not used in emergencies
Describe the indications for laparotomy
Perforation
Intraperitoneal bleeding
Penetrating trauma
Malignancy (resection)
Describe the procedure for laparoscopy
- Make 3-4 0.5mm incisions for entry, usually 1 umbilical
- Tilt table, inflate abdo w carbon dioxide gas
- Insert trocars + instruments
Describe the post-op side effects of laparoscopic surgery + post-op care
- Bloating
- Nausea
- Pain in chest/shoulders/neck
May go home same day depending on complications
Return to work after 1 week ish
Describe the indications for liver transplant
Acute liver failure eg paracetamol OD, hepatitis
Cirrhosis
Malignancy
Describe the complications of liver transplant
Intra-operative: bleeding, bile leak, damage to surrounding structures
Anaesthetic
Short term post-op: delayed graft function, pain, wound infection, anastomotic leak, DVT
Long term post-op: recurrence, graft rejection, comp of immunosuppression
Describe the relevant liver anatomy + types of resection
Liver divided into 2 lobes + 8 segments
Each has own portal triad (hepatic A and V, portal V)
Anatomic resection: resection of lobes/segments
Non-anatomic resection: resection of lesion w/o regard to lobes/segments

Others:
-Gastric banding
