The importance
of QOL…

Pylorus
Preserving
Billroth I
Pros
o
Less dumping syndrome
o
Less gastritis
o
Less reflux esophagitis
o
Less gallbladder stones
Cons
o
More delayed gastric emptying
o
(Limited oncological dissection)
Gastric reconstructions

and pyloric branchs
Preservation of coeliach
branch
Preservation of infrapyloric
vessels

Cons
Theoretically better for
Reflux esophagitis
early stages proximal
Improved cancer

Ivor Lewis – Personal Tecnique
o Narrow gastric conduit
o Intramediastinical conduit position
o GERD reduction
Termino-Terminal
Anastomosis
o Better vascularization
o Avoids the “could de sac”
o Without weaknesses
Prefer intrathoracic
anastomosis
o Eases the venous outflow
o Less tension on the anastomosis
o Over-azygos for GERD reduction
o Shorter conduit with better vascularization

Prophylactic Cholecistectomy?
Rationale
o Higher risk of gallstones formation





Vagal denervation
Postoperative fasting
Extent of lymphadenectomy
Extent of gastric resection
Digestive reconstruction
o Difficult endoscopic management (Roux-en-Y)
o Higher morbi-mortality for subsequent cholecistectomy
Physiophatology
Alteration in hormons
production: cholecystokinin and
secretin
Altered motility
Altered secretions
hepatich branch of vagus
nerve
Altered motility
Cholelythiasis
In general
Symptomatic in
population 10%
…5 y after gastric
surgery
15-25% develop
cholelythiasis
30%
o
16 studies (retrospective and prospective)
o
3735 pz
CCE: cholecistectomy
High morbidity in
delayed CCE
Low additional
morbidity for the
whole cohort
Gillen, et al.(2010) World J Surg
o

o

Simultaneous cholecystectomy
seems not to be necessary

o
Propylactic cholecystectomy (PC) VS standard surgery (SS)
o

Overall:
PC 25% vs SS 17%

Biliary:
