Transduodenal resection of the papilla of vater Tumors arising in the region of the papilla of Vater may have their origin from the distal bile duct, the duodenum, the ampulla of Vater itself, or the pancreas. Because the epithelium of origin is often impossible to determine and because their clinical characteristics are similar, these tumors are often described as periampullary tumors.

General principles and preoperative approaches Although pancreatic cancer is the most common of periampullary tumors, cancers of the ampulla, the duodenum, and the distal bile duct have a better long-term survival after curative pancreaticoduodenectomy. Although rare, there also are cystic pancreatic tumors and endocrine tumors, for which surgical extirpation is indicated. Anatomic considerations (see chapter 1 ) It is essential that the surgeon be familiar with…
Introduction This chapter addresses the resection of primary malignancy of the intrahepatic and extrahepatic biliary tree. Gallbladder cancer is an important extrahepatic biliary cancer that is often discovered incidentally. Cholangiocarcinoma occurs at the biliary confluence, in the mid-duct, or in the distal duct presenting as a periampullary tumor (see also Chapter 11 ). Three distinct macroscopic subtypes of cholangiocarcinoma are well described: sclerosing, nodular, and papillary…
Cholecystectomy Open cholecystectomy for cholelithiasis is performed only in cases in which laparoscopic techniques do not allow a safe procedure. Cholecystectomy is also part of other operations, such as liver resection and pancreaticoduodenectomy. Basically, two techniques are used to perform cholecystectomy: (1) the retrograde technique, with initial dissection of the hilar structures of the gallbladder in Calot’s triangle, and (2) the anterograde or fundus-down technique, in…
Introduction Most hepatic cysts, regardless of type, remain asymptomatic, and hepatic function is not affected. Occasionally cysts are the focus of hemorrhage or infection, or produce hepatic dysfunction by bile duct compression or portal hypertension. This chapter emphasizes open surgical approaches to cystic disease of the liver. Diagnosis Ultrasound Simple cysts are characterized by acoustic enhancement posterior to the mass. They are solitary, thin-walled without focal…
Wedge resection Wedge resection of peripherally placed lesions within the liver is carried out easily for tumors measuring up to 2 to 3 cm in diameter. However, lesions occupying the convex surface of the liver and away from the free edge, such as lesions within segment VIII, are much more difficult to approach. Wedge resections, especially for lesions situated on the dome of the liver, are…
Introduction * * Note that resection of segments II and III (left lobectomy) in this text is described as a major resection in Chapter 5 . Segmental resection conserves functional liver parenchyma and minimizes the physiologic impact of liver resection. This is of particular benefit in a cirrhotic patient with impaired hepatocellular function. Segmentectomy may be regarded as a unisegmentectomy, when one segment is removed, or…
Left hepatectomy * Inflow control The hilar plate is lowered. The left hepatic artery is ligated and divided. Any accessory or replaced hepatic artery arising from the left gastric artery is similarly ligated. Dissection at the base of the umbilical fissure exposes the left portal vein. It should be controlled at this point and not at its origin from the main portal venous trunk. If the…
Right hepatectomy * Laparoscopic hepatectomy The indications for hepatectomy are the same whether done by open or laparoscopic technique. It should be emphasized that laparoscopic hepatectomy is a complex procedure and requires expertise both in laparoscopic techniques and open liver resections. Most importantly, understanding intraoperative anatomy is critical to avoid biliary or vascular injuries. The selection for candidates for laparoscopic liver resection is based on tumor…
Right hepatectomy * Inflow and biliary control The hilar plate is opened to expose the left hepatic duct and the confluence of the bile ducts. The cystic duct and the cystic artery are exposed, ligated, and divided ( Fig. 3.1 ), and the gallbladder is removed. The cystic duct is transfixed before being ligated, and a tie is left on the cystic duct for later retraction.…
Introduction Partial hepatectomy is possible because liver regeneration is rapid (Plate 1) and because the liver is segmental in structure (Plate 2) . Hepatic resection for removal of lesions of the liver may be necessary for a wide variety of conditions ( Table 2.1 ). Table 2.1. Most Common Conditions for Which Liver Resection May Be Used for Therapy Benign liver tumors Hemangioma Adenoma Focal nodular…
Liver Gross anatomy The liver lies under the cover of the lower ribs, applied to the undersurface of the diaphragm, and is astride the inferior vena cava (IVC) posteriorly. Most of the bulk of the liver lies to the right, where the lower border coincides with the right costal margin, but it extends as a wedge to the left of the midline between the anterior surface…
The advent and refinement of minimally invasive surgery (MIS) techniques within the realm of oncologic hepatobiliary surgery (see Chapter 127 ) has paved the way for the collateral development of this field in living donor liver transplantation (LDLT) (see Chapter 121 ). Further to the initial French report of laparoscopic donor left lateral segmentectomy two decades ago, there has been a gradual accrual of literature in…
Introduction Hepatic arterial infusion was described nearly six decades ago as a regional treatment of hepatic tumors (see Chapters 50 , 90 , and 97 ). Robotic-assisted approaches to placement of hepatic arterial infusion pumps have become more prevalent following the rise of minimally invasive hepatobiliary techniques over the past 20 years. The robotic-assisted approach to HAIP placement is associated with lower intraoperative blood loss compared…
The increasing use of laparoscopic procedures has been driven by the ability to perform surgery through small rather than large incisions, with reduced postoperative pain and enhanced recovery. This began with laparoscopic cholecystectomy (see Chapter 36 ) introduced in 1988 and almost universally adopted within 2 years, although without a proper randomized controlled trial (RCT), because its advantages appeared evident to surgeons, physicians, and patients. The…
Introduction When hepatobiliary surgeons consider what treatment is best for a patient with a tumor in the liver, several questions must be answered. What kind of tumor is it, which resection margin is necessary, is the liver sick or healthy, is the liver remnant sufficient, is there more than one tumor, did the patient undergo surgery before? When these questions and others have been answered, the…
Introduction Since its initial description by Codevilla in 1898, through the first procedure performed by Kauch in 1909 and the two-stage procedure described by Whipple in 1935, the pancreaticoduodenectomy (PD) technique has evolved significantly over the last decades to become a common and safe procedure in pancreatobiliary surgery (see Chapters 62 and 117A ). Currently, PD is executed routinely with low morbidity and mortality rates when…
Introduction Minimally invasive distal and central pancreatectomies are well accepted as safe and effective surgical approaches for the management of left-sided pancreatic lesions. , Several variations exist in the minimally invasive techniques, which will be detailed in this chapter. The indications and outcomes for minimally invasive compared with open approaches are addressed elsewhere (see Chapters 117B and 127 ). Laparoscopic distal pancreatectomy The two most common…

Introduction Diabetes mellitus is associated with extensive morbidity and mortality and represents a significant medical, financial, and emotional burden on society. Long-term diabetes mellitus is frequently associated with cardiovascular, cerebrovascular, peripheral vascular, neurologic, renal, and ophthalmologic complications. Diabetes remains the leading cause of renal failure (44% of new cases every year) and increases the risk of mortality in uremic patients. Despite marked improvements in the medical…
