More recent demographics

• 222 ulcer operations 1981-1998 (UCLA)– No change in mortality (13%)– Decrease in annual number of operations (24 to

11.3)

– Increased percentage of patients needing urgent surgery

– No change in percentage of patients explored for uncontrolled hemorrhage despite endoscopy

Towfigh et al, American Surgeon, 2002

Page 6: Complications of pud

Poland, 1977-81 vs. 1992-96

• Decreased surgery overall (360 vs. 246)

• Increased operative patient age and percentage of women in later period

• Decreased number of patients with obstruction

• No change in number of patients needing surgery for bleeding or perforation

Janik, et al, Medical Science Monitor, 2000

Page 7: Complications of pud

UT San Antonio 1980-1999

• 80 % decrease in number of ulcer operations performed– 70/year early 1980’s, 14/year late 1990’s

• Decreased need for surgery most pronounced for intractability (95%), but also diminished for complicated peptic disease (86% hemorrhage and 36% perforation)

Schwesinger et al, J Gastrointest Surg, 2001

Page 8: Complications of pud

Bleeding

• When should operation be performed?

• What operation should be done?

Page 9: Complications of pud

Clinical predictors of continued/recurrent bleeding

• Shock (SBP < 100 mmHg)

• Anemia (hemoglobin <7, <10)

• High transfusion requirement (2000 cc/24, 5 units total)

• Age > 60 (comorbidities)

• Bleeding rate of > 600cc/hour as measured hematemesis

Page 14: Complications of pud

Summary of rebleeding risk data

• Clinical and endoscopic features can predict rebleeding and mortality

• Early operation an appropriate consideration, ideally after stabilization, if rebleeding risk is high

• Availability of endoscopic hemostatic techniques can greatly diminish need for urgent surgery in many, but not all cases

Page 15: Complications of pud

Value of endoscopic rx and re-rx• 80-100% initial hemostasis rates• 75% success with endoscopic retreatment

– Slight increased risk of perforation with thermal re-rx

• Randomized trial for rebleeding shows decrease in overall complications and need for surgery with endoscopic re-rx, with no increase in mortality– Hypotension at randomization and ulcer size>2

cm predictive of higher failure with endo re-rxLau et al, NEJM, 1999

Page 16: Complications of pud

Does Endoscopic Rx Affect Outcome?

• Metanalysis all randomized controlled trials– 62% reduction rebleeding– 64% reduction need for operative intervention

– 45% reduction mortality

– Cook et al., Gastroenterology 1992;102:139

Page 17: Complications of pud

Choice of operation--gastric ulcers

• Generally higher rebleeding rate with gastric lesions (30% with simple oversew), also increased risk of neoplasia (10%) compared to duodenal

• Location and setting influence choice of operation

Page 18: Complications of pud

Gastric ulcer typology (Modified Johnson Classification)

• Type I: incisura, lesser curve

• Type II: associated duodenal ulcer disease

• Type III: antral/prepyloric

• Type IV: high lesser curve/gastroesophageal junction

• Type V: associated with NSAID use

Page 19: Complications of pud

Choice of operation--type I, II, III

• Distal gastrectomy incorporating ulcer and Billroth I reconstruction– no vagotomy necessary in pure type I setting– add vagotomy if type II, ongoing ulcerogenic

stimulus (alcohol, steroids, NSAID’s), type III within 3 cm of pylorus

– Consider vagotomy and pyloroplasty with bx and oversew or wedge excision if unacceptable risk for gastrectomy, accept 15% higher risk of rebleeding

Page 20: Complications of pud

Billroth I (gastroduodenostomy)

Page 21: Complications of pud

Billroth II (gastrojejunostomy)

Page 22: Complications of pud

Choice of operation--type IV• Pauchet procedure (distal gastectomy with

lesser curve tongue-extension to incorporate higher ulcer and Billroth I reconstruction)

• Csendes operation (gastrectomy incorporating portion of GE junction on lesser curve side and esophagogastrojejunostomy)

• Kelling-Madlener procedure (antrectomy with oversew/bx of ulcer left in situ)

Page 23: Complications of pud

Csendes operation

Page 24: Complications of pud

What about parietal cell vagotomy?

• Acceptably documented in elective setting for gastric ulcers (with ulcer excision)

• Caveats in bleeding setting:– experience/time issue in emergent setting

– risk of damage to nerves of Laterjet with oversew/biopsy of lesser curve ulcer

– higher recurrence rates with type III, can decrease with addition of pyloroplasty

Page 25: Complications of pud

A few thoughts on reconstruction...

• Billroth I most “anatomic”– No afferent loop or retained antrum issues

• Billroth II if inadequate length, duodenal status marginal

• Roux en Y if reflux a major concern; risk of Roux stasis/emptying difficulty must be considered--best if very small gastric remnant

Page 26: Complications of pud

Operation for bleeding duodenal ulcer

• Support for PCV with oversewing of ulcer bed in this setting, particularly in stable, younger, healthier patient population– Miedema, Jordan (both 1991): one death in 79

patients, 1.3% rebleeding risk (combined series)

• Caveat that relatively few patients in era of endoscopic hemostasis come to surgery with above credentials

Page 27: Complications of pud

Operation for bleeding duodenal ulcer

• Truncal vagotomy and pyloroplasty with oversew most attested and efficient operation in less stable patient

• Antrectomy a useful alternative in stable patient with large ulcers (>2 cm)– Increased bleeding and rebleeding with giant

ulcers– Nissen closure technique can be a helpful

adjunct with large posterior ulcers into pancreas or adjacent structures

Page 28: Complications of pud

Nissen closure of duodenal stump

Page 29: Complications of pud

Conservative vs. conventional surgery

• Prospective, randomized multicenter trial

• Simple oversew and ranitidine vs. TV&P or T&A– Similar mortalities (13-16%)

– High rebleeding (11%) in simple oversew group with attendant high mortality (86%)--trial stopped

Poxon et al., Br J Surg 1991

Page 30: Complications of pud

Technique of oversew

• Four deep circular suture technique may miss vessel entering posteriorly

• Superior, inferior, posterior mattress technique

What about H. pylori?• Clear data available showing lower

rebleeding rates with H. pylori eradication– Rokkas, Gastrointest Endosc 1995;41:1-4– Jaspersen, Gastrointest Endosc 1995;41:5-7

Page 33: Complications of pud

Counterargument

• Conversely, only 10% of HP+ patients develop PUD, of those only 20% bleed, and only 10% of those come to surgery for bleeding (0.2% of total infected population)--may be other factors which need to be considered before accepting minimal surgical approaches

Page 34: Complications of pud

Is bleeding different?

• Decreased rapid urease sensitivity with bleeding– False negative CLO 18% with bleeding, only 1% w/o

• Lee et al, Am J Gastroenterol 2000; 95:1166-1170

• Surgical bleeding patients HP + only 40-55% of time in most studies

• U. Tennessee study: emergency surgery for bleeding 1993-1998– H. pylori positive (specimen histology) 68% duodenal

and 19% gastric (<usual ulcer pop.)– No correlation NSAID use with H. pylori status– No patient rebled (33 V&A, 6 V&oversew)

Callicutt et al, J Gastrointest Surg, 2001

Page 35: Complications of pud

Gastric outlet obstruction

• Acute vs. chronic, natural history

• Nonsurgical options

• Surgical options

Page 36: Complications of pud

Natural history--peptic gastric outlet obstruction

• 68% of acute obstructions and 98% chronic obstructions ultimately require surgery

Weiland, 1982

Page 37: Complications of pud

? Nonoperative strategies for peptic GOO

• Balloon dilation– ASGE survey: 76% immediate improvement,

but only 38% objective improvement at 3 mos.– Kozarek: 70% asymptomatic over mean follow

up of 2.5 years, however 52% had active/acute component when dilated and included patients with anastomotic and NSAID-induced GOO as well as peptic (Gastrointest Endosc, 1990)

– Technique: 15mm balloon, 2 one-minute inflations

Page 38: Complications of pud

GOO--? Just do the antibiotics

• 22 consecutive patients with benign peptic stenosis (16 duodenal, 6 pyloric)

• Eradicative triple therapy followed by 8 weeks PPI

• 20/22 fully resolved clinically and endoscopically within 2 months

• No recurrence at mean follow up of 12 months

Brandimarte et al, Eur J Gastroenterol Hepatol, 1999

Page 39: Complications of pud

GOO--surgical options

• Issues– Parietal cell vs. truncal vagotomy– Dilation vs. drainage

– Type of drainage procedure • pyloroplasty/duodenoplasty (Heineke-Mikulicz,

Finney)• gastroduodenostomy (Jaboulay)• gastrojejunostomy

• antrectomy/anastomosis

Page 40: Complications of pud

Pyloroplasties

Page 41: Complications of pud

GOO--vagotomy• Multiple studies attest PCV minimizes

recurrence when accompanied by drainage procedure (decreased gastrin), with less delayed emptying/postgastrectomy sequelae than seen with TV– Recurrence 0-5%, 95+% of patients Visick I or

II--Bowden, Donahue– Delayed emptying 0 (PCV) vs. 33% (TV)--

Gleysteen

Page 42: Complications of pud

Dilation vs. drainage

• Operative dilation (digitally or with Hegar dilator) has 7% recurrent stenosis rate with relatively short follow up, even when combined with parietal cell vagotomy

• Drainage procedures therefore more appropriate

Mentes, Ann Surg, 1990

Page 43: Complications of pud

GOO--type of drainage procedure

• Duodenal status limits procedures which directly approach site of obstruction

• Extended pyloroplasties and Jaboulay make reoperation more challenging, if required

• Antrectomy irreversible, contributes to higher incidence postgastrectomy sequelae

• Overall, gastrojejunostomy appears to be best choice for GOO due to duodenal ulcer

Csendes, Am J Surg 1993

Page 44: Complications of pud

Gastrojejunostomy--where and how?

• Near greater curve, retrocolic, with distal aspect approximately 3 cm proximal to pylorus– Posterior and near antroduodenal pump for

emptying, short and undistorted afferent limb

“Expert” opinion

Page 45: Complications of pud

Peptic perforation

• Nonoperative treatment

• Operative treatment– risk status

– definitive surgery vs. simple closure– ? laparoscopy

• What about H. pylori?

Page 46: Complications of pud

Nonoperative treatment• Water soluble contrast study documenting

sealed perforation

• Age<70

• NG tube, antibiotics, acid suppression, IVF

• Improving exam and clinical signs within 12 hours

• 70% success rate in avoiding surgery, 35% longer hospital stay

Crofts, NEJM 1989; Berne, Arch Surg 1989

Page 47: Complications of pud

Operative treatment--risk assessment

• Multiple studies show mortality a function of risk status, independent of operation performed– Age>70, perforation>24 hours, SBP<100,

poorly controlled comorbid conditions define high risk patient

Hamby, Am Surg 1993

Page 48: Complications of pud

Graham patch

Page 49: Complications of pud

Benefits of definitive operation• High risk of recurrent ulcer disease (48-

60%) if simple closure done, though this can be lowered by longterm acid suppression

• PCV lowers above to 3-7%, can be combined with patch closure

• Not advised in setting of shock, significant comorbidity, gross peritonitis

Griffin, Ann Surg 1976Jordan, Thornby Ann Surg 1995Feliciano Surg Clin N Am 1992

Page 50: Complications of pud

Parietal Cell Vagotomy

Page 51: Complications of pud

What about laparoscopy?

• Small series published detailing feasibility and efficacy of laparoscopic (and combined endoscopic/laparoscopic) patch procedures in selected patients

• Laparoscopic vagotomies also described and reported in small series (Taylor, truncal, true PCV)

• Remember for gastric lesions, excision or biopsy as a minimum advised

Page 52: Complications of pud

…and H. pylori?

• 83 patients with perforated DU– 47% H. pylori + (similar to non-ulcer controls)– No differences in age, smoking, EtOH, prior hx

DU, and NSAID use

– Concluded that unlike chronic uncomplicated DU, perforation has no correlation with H. pylori positive status

Reinbach, Gut 1993

Page 53: Complications of pud

An opposing view...

• 47 consecutive perforated ulcer patients– 73% H. pylori +– 38% closed laparoscopically, all treated with

simple closure• Morbidity and mortality significantly higher in

laparoscopic group

– Eradicative rx successful in 96% (triple rx)– No recurrence or delayed mortality at median

of 43.5 month follow upMetzger et al, Swiss Medical Weekly, 2001

Page 54: Complications of pud

Randomized trial, Ng et al, Ann Surg 2000; 231:153-158

• 104 patients with perforated DU and HP + on biopsy at time of simple patch closure

• Randomized to either eradicative therapy or 4 weeks omeprazole

Is H. pylori a risk factor after definitive ulcer surgery in general?

• 93 patients with dyspepsia after prior ulcer surgery (78% partial gastrectomy, 22% vagotomy and drainage)– Prevalence of H. pylori not statistically

different in patients with or without ulcer recurrence

Lee et al, Am J Gastroenterol, 1998

Concluding comments

• Know your patient (risk status, chronicity, compliance)

• Know your self (training, competence)

• Know your setting (resources, support, endoscopy, blood bank, monitoring capability)
