Q

Describe a subtotal gastrectomy c RNY for gastric cancer?

A
  • Subtotal Gastrectomy c RNY DI resection (supra and infrapyloric LN and along greater and lesser curves)
    • supine incase of right thoracic or cervical approach
    • laparoscopy exploration catches 30% mets not seen on CT scan
    • Palpate liver
    • Dissect omentum from L transverse colon
    • Mobilize Left colon from spleen (resect spleen if involved)
    • Lift stomach and determine if involves transverse mesocolon
    • Biopsy celiac node and if negative may proceed with resection for cure
    • Biopsy porta hepatis
    • determine if possible to resect with 5 cm margins
    • Dissect along greater curvature of stomach to 5 cm margin from tumor and mobilize
    • Kocherize duodenum and divide using GIA taking care to avoid retained antrum
    • Dissect along port hepatic toward celiac axis to take all nodal tissue
    • divide L gastric at its origin and nodal tissue is swept from crus and hiatus
    • Proximal splenic artery is dissected along superior border of pancreas and nodal tissue is taken so splenic hilum
    • Subtotal gastrectomy - divide proximal stomach with GIA
    • Total gastrectomy - encircle esophagus with penrose, control c satinsky clamp and transect
    • send proximal margins for frozen
    • reconstruct c RNY gastro or esophagojejunostomy (D1 resection)
    • Adjuvant chemoradiation is questionable f(5FU and (radiation decreases recurrence))
    • feeding J
    • drains to the stump and EJ anastomosis check amylase and bilirubin
    • NGT beyond GJ anastomosis

A

Sleeve

- no foley
- no arms tucked
- veress
- two 5 and 12 in the upper quadrants

  • PE-distended, Hernias, abdominal masses, lymphadenopathy, Cirrhosis stigmata
    • high pitched and very tympanic more distal small bowel or large bowel
  • mechanical vs ileus?
  • partial vs complete?
  • simple or strangulating?
93
Q

SBO work up?

A
  • acidosis lactic acid, e-lytes
  • abdominal films - dilated loops, air fluid level
  • CT scan
    • fluid filled stomach, transition pt, complete, pneumotosis and portal vein air, swirl si, bowel wall integrity decreased enhancement, intuss, hernia, volvulus, neoplasm
94
Q

    • NGT (follow outputs), fluids, NPO, +/- ABX foley
    • Follow lactates!
    • bowel rest if PSBO if 2/2 to adhesions give it 48hrs and if no improvement
    • If patient without h/o surgery or trauma sugg of duodenal HTA then likely pt will require surgery
      • get a contrast study to evaluate progression
      • can follow with serial films watching the contrast hopefully makes it to the end of colon in 24hrs
      • or if worsens F, tacky, pain out of proportion to PE
      • 65-80% resolve without surgery
      • OR if complete, LBO or strangulating
95
Q

Post op obstructions?

A
  • Note- Remember bariatric patients high risk fro internal hernias
  • Note- post op obstructions
    • usually resolve w/in 14 days NPO, NGT, TPN w/in first 7 days of NPO
    • If worsens before 14 days —>OR
    • after 14 days adhesions are dense, poorly defined, highly vascular
    • If low grade partial obstruction wait 3-4 wks then go back and do complete
  • post operative
    • SBO give 14 days to resolve if worsens then go to OR before.
  • Note-
    • after 14 days the adhesions are dense, poorly defined, highly vascular.
    • if low grade psbo then go to the OR in 3-4weeks and do a complete LOA
    • Postop laparoscopic surgery SBO needs immediate exploration 2/2 port site herniation or internal hernias
    • Look out for obturator hernias (CT scan fluid filled structure behind pubic ramus)
96
Q

SBO surgery?

A
  • Surgery
    • eval bowel with doppler US mesenteric side of the bowel and rare cases flourescein dyes eval
    • reduce intussusception with gentle traction
    • crohns stricturoloplasty rather than resection
    • Check for gallstone ileus
      • XRAY- showing air in biliary tree or large stone in RLQ
      • No point in waiting 2-3 days
      • Obstruction in the pylorus or MC is ileocecal jxn.
      • ID point of obstruction and milking the stone proximal to an area not inflamed and remove via enterotomy
      • palpate entire bowel r/o other stones
      • usually really elderly and sick so 2nd procedure is probably best
        • 1st remove stone, close transversely
        • 2nd 6-8wks later if even at all for cholecystectomy /TD and 2 layer closure and cholangiogram
    • Hernia- see section

    • if drops back in prior, perform a diagnostic laparoscopy in same setting if you want to avoid a laparotomy
    • Find coopers ligament
    • reduce the hernia
    • divide the ligament if needed

102
Q

Cholecystodoudenal Fistula surgery? Note?

Postop?

A
  • Surgery
    • Primary goal is remove obstruction quickly and safely (sites are distal ileum, jejunum, gastric outlet) vast majority of patients
    • usually midline laparotomy
    • proximal! longitudinal enterotomy on anti mesenteric border distal to the stone and retrograde retrieval (ante grade causes more mucosal damage) sometimes bowel resection is necessary
    • run the entire bowel
    • really try to avoid cholecystectomy (lot of inflammation) and fistula takedown (depending on size primary repair, omental patch, pyloric exclusion) significant increase in operative time and increases risk of morbidity and mortality. may consider in patient very stable, minimal comorditiies. not to mention possible leaks after repairs which could be disastrous. if you do repair it get an UGI postop
  • Note-
    • Risk of recurrent gallstone ileus or comp to fistula is very low. generally closes spontaneously without stones
  • Postop
    • NGT, IVF, bowel rest
    • may consider interval cholecystectomy who recovers fully and good operative candidate at least 4-6 wks out

A
  • Treatment
    • 1st Phase
      • fluid resuscitation (e-lytes low K and Cl), NGT, Foley, NPO, Central Venous Access TPN
      • ABX (if signs of infection), PPI, or H2 blockers (decreases gastric and intestinal secretions and reduces stress ulcers)
      • wound vac, appliance, skin barriers
      • Consider Octreotide (can decrease output not closure)
      • Note- nutrition adjust TPN (TPN %25 glucose 4%AA 10%FFA (50% non -protein cal to be glucose and 50%FFA 1 g/kg/day protein, 25 Kcal/kg/day carb))
    • 2nd phase
      • Will not heal if FRIENDS
      • after 7-10 days fistula track is matured enough to place a catheter to fistula delineation -fistulogram r/o leak or UGI
      • tracks longer than 2 cm more likely to heal, site of bowel injury, intestinal continuity and distal obstruction
    • 3rd Phase
      • need to decide when to operate based on location
      • Unlikely to heal 50%
        • Oropharynx, esophagus, duodenal stump, pancreatic-biliary and jejunum
      • 5-6 weeks if nutrition is ok and fistula is unlikely to heal consider surgery
      • Uncontrolled sepsis - need to operate sooner if you can’t find an abscess that can be perc drained
      • If patients situation is extremes, then divert the bowel and repair the fistula later
107
Q

ECF definitive treatment?

A
  • Definitive treatment
    - open abdomen and TD all adhesions
    - small bowel segment c fistula needs to be resected
    - Place feeding tube
    - cont 5-10 days of TPN after
108
Q

ECF wait period? Note?

A
  • Note- some wait 6mo-12 mo for bowel adhesions to soften and optimize patients infxn, nutrition,wound status
  • Note- surgery new site entrance and extensive LOA if possible to avoid recurrence, drain abscess, ostomy to protect resection anastomosis if necessary depending and not a simple closure of fistula site which has a high risk of recurrence

      • useful for staging
114
Q

Carcinoid Tumors treatment location?

A
  • Treatment
    • depends on location and size of tumor (2 cm is magical!) Beyond it becomes malignant and mets
    • duodenum - 2 cm whipple
      • if hepatic mets then locally debunk (to help c symptoms ) and post operative medical tx
    • ileum and jejunum - wide local resection c en bloc mesentery resection, hepatic mets debulk
    • Appendix- >2 cm or at the base (may extend further then you think —> right hemicolectomy
      • Tip and 2cm or invade the muscularis propria —> APR
    • Mets to liver-
      • only wedge resection at original surgery don’t do extensive resection
      • remove primary lesion, get baseline 5-HIAA and observe patients symptoms
      • plan resection or ablation of these lesions after there is clear assessment of the disease

A
  • cenario- “A young patient with few months history of intermittent abdominal pain, low grade fever, mucoid/slightly bloody diarrhea, losing weight or slightly anemic”
  • Note- abdominal pain > bleeding (UC), skip lesions, transmural, granulomas, small bowel and perianal dz
122
Q

Small Bowel Crohns Disease H&P, PE

A
  • H&P- Pain, previous episodes, FHx, bowel habits, N/V, previous perirectal abscess, rectal bleeding

123
Q

Small Bowel Crohns Disease w/u?

A
  • Invasive/ Radiology (eval for IHOP)
    • Flat and upright XRAY r/o obstruction
    • sigmoidoscopy un prepped r/o UC (starts at rectum and progresses proximal no skip) and bx abnormal tissue, perianal fistula
    • Meckels if strong “bleeding picture”
    • If no obstruction on X-ray and sigmoidoscopy is negative and no peritonitis
      • Barium UGIS c SBFT look for crohns stigmata (strictures, TI (almost always involved) extent of disease
    • BE to look for colon involvement
    • Colonoscopy if colon involved c biopsies
    • CT A/P r/o path - small bowel wall thickening and mesenteric inflammation, fistula, transition points, masses, to look for relationship of disease segments and adjacent organs
124
Q

Small Bowel Crohns Disease treatment and operation?

A
  • Treatment/Operation
    • initially mostly medical
      • acute flare up
        • Prednisone 40 mg/d (is tapered over 4 weeks)
        • Sulfasalazine 0.5mg/d or mesalamine (dz modifier)
        • Flagyl for perianal dz
          • may consider Remicade-anti-TNF ab to establish remission in refractory patients
125
Q

Small Bowel Crohns Disease indications for surgery?

A
  • Indications for surgery
    • Severe symptoms as surgery doesn’t cure
    • Obstruction
    • Intraabdominal abscess
    • Symptomatic fistula (enterovesical, enterocutaneous - enteroentero may not need sx)
    • Intractable bleeding
    • Cancer (increase risk)
    • FTT in children
    • Failed medical control of symptoms (toxic megacolon Wbc>12.5, HR>100 temp>38.5, traverse colon >5cm)
    • Perianal dz
126
Q 
Small Bowel Crohns Disease surgery?
IA abscess?
Fistula?
Appy?
fistula?
intractable colon involvement?
A
  • Surgery
    - nutritional optimized
    - preserve small bowel length, least amount of surgery possible, no frozens for margins, just grossly, stricturoplasty if extensive
    - contraindications
    - perforation, mult strictures in a short segment, colonic stricture, suspect cancer and a stricture close to the proposed area to resect
    - grossly involved bowel- resect c primary anastomosis
    - if duodenum involved - then bypass with gastrojejunostomy c truncal vagotomy if there is a fistula
    - fistula- usually aggressive and requires a “cool-down” period, on third need to be taken down and resect involved small bowel and repair bladder c omentum interposed
    - IA abscess- perc drain abx and plan surgery after inflammation decreased 4 weeks later should be kept NPO and TPN in the meantime
    - If during appy- perform appy if base not involved, if its involved forego the appy for fear of fistula formation
    - Distal anal stricture- dilate vs permanent diversion
    - Anal fistula - setons, try to minimize surgery here to avoid injury to the sphincter
    - If extensive colonic involvement and rectum with incontinence - can consider total proctocolectomy with end ileostomy (lowest recurrence rate)
    - Intractable colon involvement- proctocolectomy with permanent ileostomy (poor results c high recurrence rates)
127
Q

Bowel Ischemia hx?

A

Hx- A. Fib, post op from heart surgery or MI, c/o acute severe epigastric pain or periumbilical pain disproportionate findings

128
Q

Bowel Ischemia initial tx?

A
  • Initial treatment
    • ABC
    • Labs
      • cbc, renal, lactate, amylase and lipase, check for met acidosis
    • EKG, cardiac enzymes, rectal exam and guaiac
129
Q

Bowel Ischemia PE?

A

PE- check for hernias

130
Q

Bowel Ischemia imaging/testing?

A
  • Imaging/ testing
    • if stable perform extended sigmoidoscopy (look for ischemic changes in colonic mucosa)
    • if suspect ischemia order a CTA or arteriogram (with papaverine drip good for non-occlusive dz)
    • Dx laparoscopy
    • If normal consider colonoscopy
131
Q

Bowel Ischemia preop?

A
  • Preop
    • IVF optimize CVP and UOP
    • ABX (Imipenem)
    • Heparin (10,000 bolus and 1000 u/h)
    • Consider dopamine and bicarb possibly post op to restore blood to bowel
132
Q

Bowel Ischemia SMA embolus ?

A
  • SMA embolus (patent proximal 3-8 cm from SMA origin)
    • Laparotomy and embolectomy
    • Expose SMA
      • transverse colon is reflected upward and the bowel is packed laterally
      • exposing root of mesentery crossing the third portion of duodenum
      • follow the middle colic artery in the transverse mesocolon
      • small longitudinal incision is made in posterior peritoneum
      • artery is ID medial to SMV
    • Transverse arteriotomy
    • flush c heparin and repair it
    • watch the bowel
      • use intraoperative doppler
        • viable bowel will have clear doppler signal on its mesenteric border
      • IV fluorescein with woods lamp
    • If segments are clearly not viable then resect
    • if questionable consider 2nd look the next day
    • Keep heparin ggt postop
133
Q

Bowel Ischemia SMA thrombosis?

A
  • SMA thrombosis (occlusion at origin of SMA)
    • laparotomy and embolectomy to SMA
    • poor flow
    • Harvest saphenous vein graft b/w soft spot in infrarenal aorta and the SMA
      • if no soft soft infrarenal then suprarenal aorta
        • approach through gastrohepatic omentum above the celiac trunk and passed behind the pancreas to SMA
134
Q

Bowel Ischemia NOMI?

A
  • Non-occlusive mesenteric ischemia (normal prox mesenteric vessels but gradual tapering and spasm)
    • Associated with low flow state (acute heart failure, dehydration)
    • Heparinization
    • papaverine infusion through the angiocatheter
    • correct underlying condition (opt intravascular volume and CO)
    • If improves repeat angiogram to confirm normal blood flow to bowel
    • if develops peritonitis then laparotomy and bowel resection
135
Q

Bowel ischemia arteriogram?

A
  • Arterial phase of arteriogram is normal but delayed, and a venous occlusion is noted on venous phase
    • also consider spiral CT delineate
    • associated with hypercoagulopathy
    • Tx
      • heparin
      • optimized medical condition and repeated exam
      • possible laparoscopy
      • possible laparotomy and bowel resection
        • ostomies and MF
        • or second look laparoscopy to check anastomosis
136
Q

Intestinal Angina hx?

A
  • Hx- postprandial pain, loss of weight, negative exam and neg GI w/u
  • Mild intermittent claudication or a smoker
137
Q

Intestinal Angina imaging/ testing surgery?

A
  • Imaging/testing
    • duplex scan to celiac artery, SMA, IMA
    • and if positive perform a CTA
      • will show two or more of three vessels
      • candidate for re-vascularization procedure
      • priority is celiac >SMA>IMA
    • Angioplasty with or without stent treatment of choice
    • if unavailable then surgery
      • transabdominally or retro
      • autologous graft b/w supraceliac aorta via gastrohepatic omentum and both celiac and SMA
        • the limb to SMA passed behind pancreas to prevent kinking near duodenum
        • other option is if infrarenal aorta is healthy then straight short graft b/w infrarenal aorta and SMA distal to its occluded segment
138
Q

intestinal angina postop?

A
  • Postop
    • re-vascularization syndrome
      • abdominal pain, tachy, wbc and intestinal edema
