The Roux-en-Y loop is tacked to the rent in the transverse mesocolon with interrupted 4-0 silks to prevent herniation of the small bowel (11). The Silastic transhepatic biliary stents are brought out through stab wounds in the right and left upper quadrants, sutured to the skin with 5-0 stainless steel wire, and connected to dependent bile-bag drainage. The egress sites of both stents on the superior surface of the liver are drained with closed-suction Silastic drains brought out through separate stab wounds in the right and left upper quadrants. A third closed-suction Silastic drain is used to drain the hepaticojejunostomy, and is brought out through a stab wound in the mid abdomen.

Cholangiography is obtained through the stents on the fifth postoperative day. If there are no leaks, the stents are internal­ized by placing three-way stopcocks or heparin locks on the ends. The patients are taught to irrigate the catheters twice a day with 20 mL of saline. The stents are left in permanently in patients with Caroli’s disease in an attempt to achieve adequate drainage, avoid stasis, and prevent episodes of cholangitis and jaundice. Whether or not transhepatic stenting decreases the likelihood of the development of cholangiocarcinoma is unknown. The stents are changed as an outpatient procedure every 3 or 4 months. During long-term follow-up, the transhepatic stents provide access for repeat choledochoscopy to look for evi­dence of the development of cholangiocarcinoma. Guidewires can be placed through the stents into the Roux-en-Y loop and the biliary stents removed (12).

Using the guidewire, a flexible choledochoscope can be placed through the skin opening and guided down into the intrahepat­ic biliary tree (13). Suspicious areas can be biopsied.

Wedge Resection of Liver and Regional Lymph Node Dissection, Resection of the Extrahepatic Biliary Tree with Hepaticojejunostomy, for Carcinoma of the Gall bladder
Operative Indications:
Carcinoma of the gall bladder is in many instances an incurable disease, and the surgeon’s role is merely a palliative one. Often, patients with carcinoma of the gall bladder pres­ent with obstructive jaundice, with tumor extending beyond the gall blad­der into the liver, and with involvement of the extrahepatic biliary tree,
Common hepatic duct
with extension to involve the portal vein and hepatic artery. Such patients are best palliated by the percutaneous insertion of a transhepatic biliary stent, or by endoscopically inserting an endoprosthesis to decompress the obstruction. An occa­sional patient presents with biliary symptoms and gall­stones and undergoes an elective laparoscopic cholecys­tectomy. At the time of pathologic examination of the gall bladder, an incidental adenocarcinoma will be found. These patients with incidental gall bladder can­cer are the ones with the greatest potential for long-term survival. Occasional patients present between these two extremes, where the neoplasm still appears to be confined primarily to the gall bladder, surrounding liver parenchyma, and regional lymph nodes (1). Although the vast majority of these patients

will not be cured, some clearly will benefit from a regional procedure.

Operative Technique:
The patient is explored through a right subcostal incision. At the time of laparotomy, a thorough exploration of the abdomen is carried out to be certain there is no evidence of disseminated disease beyond the immediate region of the gall bladder and the liver, or to extrahepatic serosal surfaces. At the time of exploration, a patient who had a preop­erative imaging CT scan or MRI suggesting gall bladder cancer will generally have a hard, thickened and whitish appearing gall bladder (2). If there is no other evidence of tumor, a cholecystectomy can be performed and the diagnosis confirmed by frozen section. If it is obvious from the beginning that a carcinoma of the gall bladder is present and can be confirmed with a biopsy, then the wedge resection of the liver can be carried out con-

Since this patient has already undergone a
laparoscopic cholecystectomy, using the
electrocautery, the margins of the wedge
resection can be outlined on the liver,
surrounding the gall bladder bed (4). The wedge resection can be performed
utilizing a variety of techniques. Many
surgeons prefer to use the Cavitron or
TissueLink for such nonanatomical liver
resections. In this example, we demonstrate
a technique of utilizing a series of overlap-

Generally, a 2 cm margin can easily be obtained using this technique. which results in a virtually bloodless resection. Small bleeding points or small bile ducts are further controlled with suture ligatures. Hemostasis can be achieved using the electrocautery and the argon beam coagulator.

Wedge Resection of Liver and Regional Lymph Node Dissection, Resection of the Biliary Tree with Hepaticojejunostomy 119
Following the local wedge resection of the liver, a regional lymph node dissection is carried out removing all lymph nodes and surrounding areolar tissue from the bifurcation of the common hepatic duct down to the distal common duct and medi­ally along the hepatic artery over to the celiac axis (6). Many nodes are actually posterior to the biliary tree. In the past, we have tried to perform this lymphadenectomy without removing the extrahepatic biliary tree. This is very difficult, and we now routinely divide the common hepatic duct just distal to the bifurcation, and include the entire extrahepatic biliary tree with the porta hepatis lymphadenectomy. This also gives a bigger margin on the gall bladder than just the cystic duct if only a cholecystectomy is performed. Following laparoscopic cholecystectomy, we have had instances when a normal-looking extra­hepatic biliary tree has been removed in the course of the porta hepatis lymphadenectomy, and a histologically positive cys­tic duct margin has been found.

Following the porta hepatis lymphadenectomy, a Roux-en-Y jejunal loop 60 cm in length is constructed in the fashion previously demonstrated (see “Insert Section Here”). It is brought up into the right upper quadrant through a rent in the transverse mesocolon on top of the second and third portions of the duodenum. A hepaticojejunostomy is performed with a single layer of interrupted 4-0 absorbable synthetic material (7) as previously described (see “Insert Section Here”). Stenting of the anastomosis is not necessary. We have generally followed the principle that, if tumor is present in the seg­ment of liver removed with the wedge resection and/or positive lymph nodes or a positive cystic duct margin is present, post-operative adjuvant therapy is carried out using both radiotherapy and chemotherapy. If these three areas are negative, adjuvant therapy is not used.
