Cholecystectomy
Operative Indications
atients with symptomatic gallstones are candidates for
cholecystectomy. In the past even patients with asymptomatic
gallstones were thought to require cholecystectomy. Howe\'<7,
recent natural history data suggest that unless patients with
gallstones have symptoms referable to their biliary tract, the likeljbrxxJ
developing significant morbidity is low enough to justify merely t
patient and performing cholecystectomy only if symptom arise. There::JaY be
exceptions to this rule. An individual living in or traveli ng to remorearea"
where medical care is not readily available may be a candidate for prophylactic
cholecystectomy if stones are present. Other factors such a diabe or other
systemic illnesses may also modify this decision. Most patients wilh
asymptomatic gallstones, however, are no longer considered candida
cholecystectomy.
lIoith
Some patients with symptomatic gallstone disease may be man

a minority of patients with symptomatic gallstones; the majority are managed
by cholecystectomy. There are also other rare indications for cho ecystectomy.

he hepatic flexu re of the colon is retracted in a caudal di rection,
frequently with a Mi kulicz pad , and the stomach is packed medially,
also with a Mikulicz pad. A clamp is placed on the fund us of the
gallbladder, and it is gen tly retracted in a cephalad direction. Thesero a
overl ying the porta hepatis is opened and the portal struct ures identified (B).
The cystic duct is identified and looped with a vessel loop. If it is doubly
looped, this will prevent gallbladder stones from passing through the cystic duct
into the common duct du ring gallbladder manipulation (C).
Dissection of Calot's triangle allows identification of the cystic artery,
which arises from the common hepatic or right hepatic artery. This anatom y is
extremely variable, and this area has to be dissected carefully and completely to
clearly identify the cystic duct and cystic artery and to avoid injuring
anomalous structures. The right hepatic artery freq uently fo llows the cystic
duct and/ or gallbladder very closely before cu rving back up into liver
parenchyma, and for a 1· or 2·cm course it can easily be confused with the
cystic artery. The arterial anatomy has to be dissected such that the cystic
artery is clearly seen joining the gallbladder before one can be certain of its
identification. Likewise the cystic duct, which usuall y arises from the common
hepatic duct, may arise from the righ t hepatic duct or from one of the two
segmental ducts to the right lobe of the liver. This area has to be carefull y and
completely dissected to be certain of the anatomy.
If the anatomy cannot be clearly delineated, one shou ld stop further
dissection in th is area and proceed to mobilize the gallbladder from above
downward. When the gallbladder has been mobilized out of the liver bed, the
anatomy of this area will become clear. Early cholangiography, performed by
injecting contrast directly into the gall bladder or ductal system, may also be
hel pful.

transverse abdominal incision is made in the anterior axillary line,
approximately 2 inches below the costal margin. In a particularly
cachectic individual with no subcutaneous tissues, the valve may be
inserted in the rectus sheath and covered by the rectus muscle. In
most instances, however, the valve is inserted lateral to the rectus sheath.
The transverse incision in the right axillary line is deepened down to the
external oblique muscles, which are spread in the direction of their fibers (C).
The internal oblique muscles are then separated in the direction of their
fibers (D), and the transversus abdominis muscle fibers on the peritoneum
exposed. In preparation for passing the tubing from the valve, in a cephalad
direction, a small opening is made through the abdominal wall muscle layers
into the subcutaneous space (D).

been previou ly identified, control of that vessel can now be
accomplished. Controversy remain as to whether or not routine
cholangiography should be performed. Our bia i that selection hould be used
and that not all patients need undergo operative cholangiography. If one is
operating upon a patient with normal liver funct ion tests and a single, large
cholesterol gallstone, the likeli hood of common duct stones is so Iowa to be
negligible, and operat ive cholangiography is unnecessary. In a significant
proportion of patients undergoing cholecystectomy, however, uperative
cholangiography will be required.
After placing a tie proximally at the cystic duct-gall bladder junction, a
small opening is made distally in the cystic duct and a cholangiocatheter
inserted (H). The cholangiocatheter is secured with a 2-0 silk that i tied around
the dista l cystic duct containing the catheter and then passed through the
opening on the catheter.
After adequate cholangiography has been obtained, the cholangiocatheter is
removed, the cystic duct is doubly clamped and divided, and the gallbladder is
removed from the operative field (1).
The cystic duct stump is then ligated with a 2-0 silk (J ). Many urgeons
contin ue to use sil k, as we do; others are concerned abou t it acting a a nidus
for gallstone form ation and thus use a synthetic absorbable material.

the electrocautery.
Whether or not to drain the liver bed and porta hepatis following routine
cholecystectomy rema ins somewhat con troversial (K). There are virtually no
significant liabilities from drain ing the operative site following elective
cholecystectomy, but many studies have shown it to be unnecessary. The only
reason for leaving a drain behind is if an unexpected bile leak occur from a
small , unrecognized bile ductule in the bed of the li ver; leaving drain in place
obviates the need for reexploration. If drains have not been placed, this can
present a serious life-th reatening complication. Even though rare, it seems to us
that the discomfo rt of a dra in is worth the avoidance of this unusual but lifethreatening complication. We prefer a closed suction drain left in place for
hours. If biliary drainage does not occu r, the drain is removed ju t prior to
discharge.

Common Duct Exploration
Operative Indications
ost common duct explorations for calculi are performed in
conjunction with cholecystectomy. In the past, patients who bad
previously undergone cholecystectomy and presented with primary
or recurrent common duct stones were also treated surgically_
Now the majority of such patients can be managed non operatively with
endoscopic papillotomy. Thus today the only patients with common duct caIaili
who routinely are treated surgically are those patien ts with a gallbladder in
place who also require cholecystectomy.
The most common indication for common duct exploration today i the
radiographic demonstration of stones in the biliary tree. T he majority of
patients in our institution who present with jaundice have their biliary tree
anatomy and pathology delineated cholangiographically prior to surgery. This is
carried out preoperatively via either endoscopic or percutaneous tran hepatic
cholangiography. However, in the event that cholangiography has not been
performed preoperatively, operative cholangiography is performed at the timed
surgery in most patients who prove to have biliary tract stones. Common dud
exploration in the absence of preoperative or intraoperative cholangiography is
infrequent in our institution. At the time of elective cholecystectomy, if a tone
is unexpectedly palpated in the biliary tree or a dilated com mon duct is
unexpectedly found, the patient would undergo operative cholangiography to
demonstra te the entire biliary tree prior to common duct exploration.

M

Operative Technique
nce the decision is made to perform a com mon duct exploration. the
duoden um is kocheri zed extensively (A). This allows one to palpate
the distal common duct as it traverses behind the first portion of the
duodenu m and head of the pancreas, prior to entering the di tal
second portion of the duodenum through the am pulla. It is impossible to
adequately palpate this portion of the biliary tree without extensive
kocherization. The common duct is cleaned fo r a 2· or 3·cm length, generaUy
between the cystic duct stump and the duodenum .
tay sutures of 5-0 synthetic nonabsorbable material are placed in the
common duct, and a choledochotomy is performed (B). The choledochotomy

duct without traumatic exten ion.

here are a variety of instruments that one can utilize to explore the
biliary tree; generally we utilize all of these instruments in an effort
to completely rid the tree of biliary calculi. It is important that the
choledochotomy be made adequate in length, so that the instrument
used to extract biliary calculi do not traumaticall y extend the incision.
A variety of scoops with malleable handles can be used to pass distally
down to the ampulla and up into the intrahepatic biliary tree via both the right
and left hepatic ducts (D). These scoops come in a variety of sizes and can be
extremely effective in removing small stones or biliary sludge.
Randall Stone forceps are also utilized, and many surgeons use these
instruments initially in the duct exploration (E). These forceps come with a
variety of curves that range from almost straight, as pictured here, to righ tangled and even acute-angled. These instruments are very effective in grasping
larger, well-formed stones.
The biliary balloon catheter is particularly usefu l; it can be passed down
distally, through the ampulla, and then inflated to document patency of the
distal biliary tree into the duodenum. This is perhaps the safest way to
demonstrate an open ampulla. In using the balloon catheter, one has to be
careful that it is not overdistended. Experimental studies have demonstra ted
intrahepatic ductal disruptions and liver abscesses formed from overinflation of
the balloon. If one constantly moves the catheter to and fro as the balloon is
inflated, being certain that the balloon catheter remains mobile within the
ductal system, overinflation is unli kely. T he balloon catheter is particularly
effective in retri.eving intrahepatic stones (F).

ne of the most effective maneuvers in ridding the biliary tree of
stones and biliary sludge is irrigation using a small French cath
A #12 French catheter placed intrahepatically into the right and I
hepatic ducts, together with large volume irrigation with saline, is
extremely effective in ridding the entire intrahepatic biliary tree of mall st
(G). This maneuver can also be carried out distally.
Passage of the French catheter through the ampulla into the duodenum is a
safe way of demonstrating ampulla patency (H).
The use of Bakes dilators is controversial. Many surgeons feel that the
potential for creating false passages, injuring the ampulla, and/or initiating
postoperative pancreatitis is so great that these metal dilators should never be
used. Other surgeons feel it is acceptable to carefully and gently utilize the
smallest Bakes dilator to demonstrate patency of the am pulla only (and not for
dilatation). Our philosophy is that it is safer to demonstrate patency of the
ampulla with either a balloon catheter or a small French catheter. Ii neither of
these is effective in demonstrating patency of the ampulla, then very cautious
and gentle use of a small Bakes dilator is acceptable. Generally the Bake dilator
easily passes gently through the ampulla, and patency can be demonstrated by
seeing the "steel gray" end of the dilator pressed against the lateral wall of the
duodenum (1). We feel there is rarely an indication for the use of a Bak dilator
larger than a #3.

any biliary tract surgeons have adopted the routine use of
choledochoscopy during common duct exploration. T hi can be
carried out with either a rigid right·angled scope or a flexible
fiberoptic instrument. Many studies demonstrate that operative
choledochoscopy significantly lowers the incidence of retained common duct
stones. The rigid scope is easier to use but allows one to visualize a relatively
smaller proportion of the intrahepatic and extrahepatic biliary tree (J).
The flexible scope is more difficult to use, but it allows the surgeon to
visualize a greater extent of the intra· and extrahepatic biliary tree (K).
With either instrument one can utilize balloon and basket catheters to
remove stones visualized in the biliary tree (insets).
Following completion of the common duct exploration, a T-tube should be
inserted routinely. Our preference is for the variety of T - tube with a larger
diameter external limb and a smaller diameter T. We further decrease the size
of the T by cutting off the back wall. A wedge should also be removed from the
back wall to allow collapse of the two T - limbs when the T -tube is removed (L
Following insertion of the T -tube, the choledochotomy is closed with a
continuous suture. Many surgeons feel that synthetic absorbable material,
either 4-0 or 5-0, should be utilized to eliminate the theoretical possibility of a
permanent suture material acting as a nidus for stone formation. Other,
however, have utilized silk, or even synthetic nonabsorbable material, without
any obvious adverse effects.
The T -tube should be brought straight out laterally, without sharp turns
to allow for easy instrumentation s ubsequently if a retained stone should be
identified (M).
Closing cholangiography should always be performed. If filling defect
suggestive of stones are seen, the duct exploration should be repeated. Except in
emergency situations, the surgeon should not rely upon postoperative mean of
stone extraction to substitute for a completely successful operative procedure. If
contrast does not enter the duodenum, glucagon should be administered. If
repeat cholangiography still does not demonstrate contrast in the duodenum,
the surgeon should consider opening the duodenum and performing a
sphincteroplasty (demonstra ted on pages 18-27) to be certain there is not a
ampullary stone. The area of the choledochotomy is drained with Penrose or
closed suction drains.

Sphincteroplasty, Including
Transampullary Common Duct
Exploration
Operative Indications
phincteroplasty is an operative procedure that has been used in a
variety of settings over the past several decades. For many years it was
utilized as treatment for recurrent acute and/or chronic pancreatitis.
This is now considered only a rare indication in an unusual instance
where the pancreatitis appears to emanate from a proximal pancreatic duct
structure. Some surgeons feel that sphincteroplasty should be added to
papillotomy of the accessory papilla when surgically treating a patient who has
recurrent abdominal pain secondary to pancreas divisum. Recently there has
been some enthusiasm for sphincteroplasty and septotomy of the pancreatic
duct orifice for the management of patients with refractory postcholecystectomy
abdominal pain, perhaps secondary to stenosis of the pancreatic ductal orifice.
Sphincteroplasty has also been utilized for calculus disease of the biliary
tract. If after a common duct exploration the surgeon is not certain that all of
the stones have been removed, some surgeons have s uggested opening the
duodenum and performing a sphincteroplasty so that any retained stones may
pass spontaneously. It is still used frequ ently for patients who have an impacted
distal common duct stone that cannot be retrieved from above through a
choledochotomy. A sphincterotomy is performed to disimpact the stone, and
most s urgeons will proceed to extend to the incision and convert it in to a form al
sphincteroplasty. Man y biliary tract surgeons utilize sphincteroplasty if a
patient is treated operatively for a recurrent or primary common duct stone.
Most of these patients are now managed with endoscopic papillotomy. If tha t is
unsuccessful and the patient requires laparotomy, most biliary tract surgeons
now feel that it is impor tant to add a drainage procedure to common duct
exploration and stone extraction in many of these patients. Sphincteroplasty
can be successfully used as the drainage procedure.
Finally, we have utilized sphincteroplasty in recent years as a means of
exploring a common duct for calcu li when the common duct is of normal or
s mall caliber. Common duct exploration through a choledochotomy and
subsequent T - tube insertion carries sign ificant morbidity if the diameter of the
bile duct is small. Exploration through the ampulla is a good alternative. T he
operative procedures of sphincteroplasty and septotomy will be demonstrated,
as well as retrograde common duct exploration through the sphincteroplasty
mClSlon.
