Q

Oesophagectomy

A
  • removal of part or all, stomach pulled up and reanatomosed to end
  • Ivor Lewis: upper ab to mob stomach and R) post-lat thoracotomy for resection of lesion and construction of anastomosis
  • thorascopic-assisted: one ab incision & 4 or 5 ports

Imps

  • avoid head down due to gastric reflux may lead to aspiration or infection
  • care with suction
  • neck motion limited to limit stress on anastomosis
  • post-op ICC

Q

Gastric/ Duodenal surgery

  • Pyloroplasty
  • Nissen Fundoplication
  • Gastrectomy
A

gastic or duodenal ulcers or gastric carcinoma

A) pyloric muscle divided and defect is sutured transversely leaving a large gastric outlet
B) anti reflux, fundus mob and loosely wrapped around lower oesophagus. Prevents acid reflux and heals oesophagitis
C) removal of all or part of stomach, closure of duodenum and anastomosis of oesophagus to jejunum

Q

Whipples procedure

A

Cancer head of pancreas

-long incision removal of pancreas, common bile duct, part of the stomach and duodenum

17
Q

Segmental/Partial colectomy

A

removal part of colon

  • Hemicolectomy: segment of colon an end to end anastomosis, no stoma
  • Anterior resection- lesions in upper rectum and lower sigmoid colon
  • Abdominoperineal resection: removal of rectum and anus for malignancy 5cm of anal verge via mid-line and perineal incisions. Permanent colostomy

Imps

  • supine, side-lying, high side-lying
  • No sitting, avoid pressure on the perineal wound,
  • Encourage mob day 1
  • Sit out of bed with custom sitting cush
18
Q

Total colectomy and protocolectomy

A

Excision of whole colon

Imps of colostomy
-check fluid level

19
Q

Vascular general surgery : implications

A
  • assess circulation and pulses, monitor signs of ischaemia
  • care during treatment (skin)
  • footwear walking
  • patient with PVD has sheepskin or bootees during their stay
  • comps include: post-op infection, aneurysm and thrombotic occlusion
20
Q

Fem pop

A
  • performed for acute or chronic ischaemia and treatment of non-healing arterial ulcers with superficial femoral or pop artery occlusion
  • Xeno graft or autograft from femoral artery to po via long incision.
  • day chest care and mob day 1 or 2
  • ensure hip not 60 when extended
  • blood rushing feeling
21
Q

Aorto-bifemoral bypass

A

Y shared Dacron graft from aorta to two femoral arteries via midline ab incision and groin incision

22
Q

Axilla-Femoral bypass

A

-Dacron graft from axillary artery to ipsilateral femoral artery

Imps
Avoid- shoulder flex >90
-Hip flex >60
-Sidelying

  • avoid using overhead ring
  • avoid constrictive clothing

23
Q

Abdominal Aortic aneurysm repair

A

-abdominal aortic aneurysm is an abnormal, weakened dilatation in the aorta

Usually present with other co-morbidities

Pre-op imps

  • <6cm limit cough/FET
  • > 6cm risk rupture therefore no cough

Post-op

  • resp failure
  • effective pain relief and wound support are essential
  • no head tilt
  • mob once CV stable
24
Q

Naso-Gastric tube

A
  • drain bile and gastric contents
  • prevent asp or regurgitation
  • Used post-op in patient with marked ileus to decompress the gut, unconscious/semi conscious patient to prevent aspiration, marked ab distension and vomiting post-op
