Abstract
This case report describes a patient who underwent segment IV hepatic resection and 7 months later developed an abdominal wall abscess. This was a foreign body reaction to the surgical clips. The patient required an exploratory laparotomy with debridement and excision of the inflammatory mass in the anterior abdominal wall. Although occurrence is rare, foreign body reactions to surgical clips have been reported, especially as a complication of laparoscopic surgery.

Abstract
Congenital intestinal malrotation is a developmental anomaly resulting from interruption of the physiological herniation and return to the abdominal cavity of the midgut during the 6th to 10th week of embryological development. Normal vascular and anatomic relationships used as landmarks during pancreaticoduodenectomy (PD) are altered in patients with congenital malrotation. We present 3 cases of PD in adults with congenital intestinal rotation disorders. Three adult patients with congenital rotational disorders required PD. Two of these patients had bilio-pancreatic tumors, and 1 cadaveric donor underwent total pancreatectomy during pancreas allograft procurement. All patients had arterial and venous anomalies around the celiac trunk and mesenteric vessels, respectively. The midgut and hindgut in each case were shifted toward opposite sides of the abdominal cavity. Modifications to the standard approach to PD were made, and outcomes were favorable in each case. Each patient showed anatomic abnormalities with the need for identifying vascular structures through their expected (or projected) course and location before parenchymal division or ligation of any vessel. This approach becomes crucial in cases of vascular anomalies, such as ones occurring in congenital malformations, and can be used in similar situations encountered during pancreaticoduodenectomy.

Abstract
BACKGROUND Despite the risks associated with transfusion, the medical community continues to view blood as a safe and abundant product. In this article, we provide an effective strategy to accomplish orthotopic liver transplantation without transfusion. STUDY DESIGN From June 1999 through July 2004, 27 liver transplantations were performed in Jehovah's Witness patients at the USC-University Hospital (24 adults, 3 children). Nineteen of these were living donor (LD) and eight were deceased donor (DD) liver transplants. Preoperative blood augmentation with erythropoietin and iron was achieved. At induction, all LD and six of eight DD recipients underwent acute normovolemic hemodilution (ANH), and the operation was conducted under conditions of moderate anemia. Cell scavenging techniques were used. Acute normovolemic hemodilution and salvaged blood were returned as needed during bleeding or on completion of transplantation. RESULTS The preoperative liver disease severity score was higher in the deceased donor group. We had 100% graft and patient survivals in the LD group, and 75% in the DD recipients. Two DD recipients died. The remaining are all alive and well, with a mean followup of 965 days (range 266 to 1,979 days) in the LD group and 624 days (range 119 to 1,132 days) in the DD group. CONCLUSIONS Preoperative blood augmentation and acute normovolemic hemodilution provide a safe cushion against operative blood loss. Elective living donor liver transplantation allows full implementation of a transfusion-free strategy in the setting of early hepatic failure, portal hypertension, and anemia. This feat is an important step toward global standardization of transfusion-free surgical practice and an important response to widespread blood shortages and transfusion risks.

Abstract
Living donor liver transplantation has come to be an acceptable alternative to deceased donor transplants. Several ethical issues related to living donation have been raised in the face of reported perioperative morbidity and mortality. We report our experience in 13 consecutive Jehovah's Witness (JW) donor hepatectomies. From June 1999 to April 2004, 13 adult JW donors underwent donor hepatectomies at the USC-University Hospital. Nine donors underwent right lobectomy with a 62% mean volume of the liver resected. Four donors underwent a left lateral segmentectomy with a mean volume of 17.8%. Cell scavenging techniques, acute normovolemic hemodilution and fractionated products were used. The mean hospital stay was 6.2 days. All donors are alive and well at a median follow-up time of 3 years and 4 months. Live liver donation can be done safely in JW population if performed within a comprehensive bloodless surgery program.

Abstract
Hepatobiliary disease, although rare, may present during pregnancy with potential complications for mother and fetus. We present two cases of choledochal cysts and one case of a hepatic adenoma diagnosed in gravid patients. All three patients had acute events or failed medical management and were successfully treated with open resection, excision, or reconstruction during the second or third trimesters of pregnancy without requiring blood transfusions or tocolytic therapy. Although conservative treatment may be indicated in select patients due to the risk of underlying disease, we recommend surgical treatment preferably in the second trimester. With diligent intra- and postoperative management, pregnant patients can safely proceed with major hepatobiliary surgery.

Abstract
BACKGROUND The role of radiofrequency ablation (RFA) in the treatment of hepatic metastases from recurrent ovarian tumors is undefined. CASE Three patients with hepatic lesions from recurrent ovarian cancers underwent a combined partial hepatectomy with radiofrequency ablation (RFA) to achieve optimal tumor cytoreduction. Follow-up radiological studies as well as serial tumor markers are consistent with disease-free survival after 39, 13, and 9 months. CONCLUSION These results demonstrate the feasibility and safety of RFA for metastatic ovarian lesions to the liver in patients previously deemed as poor or non-surgical candidates, and suggest the potential for improvement in survival over unresected patients or in patients resected with residual disease.

Abstract
Indisputably, liver transplantation is among the most technically challenging operations in current practice and is compounded by significant coagulopathy and portal hypertension. Recombinant human coagulation factor VIIa (rFVIIa) is a new product that was initially described to treat bleeding in hemophilia patients. We present in this paper 10 liver transplants in Jehovah's Witness patients using this novel product at University of Southern California-University Hospital. The subject population included nine males and one female with an average age of 50 years. Six patients underwent cadaveric and four live donor liver transplantation. Surgeries were conducted following our established protocol for transfusion-free liver transplantation, which includes preoperative blood augmentation, intraoperative blood salvage, acute normovolemic hemodilution, and postoperative blood conservation. Factor rFVIIa was used at a dose of 80 microg/kg intravenously just prior to the incision in all patients, and a second intraoperative dose was used in 3 patients. All living donor liver transplantation (LDLT) recipients did well and were discharged uneventfully with normal liver functions. Two of the six cadaveric recipients died. One patient died intraoperatively from acute primary graft nonfunction, and the other died 38 hours postoperatively from severe anemia. This report suggests factor rFVIIa might have a much broader application in surgery in the control of bleeding associated with coagulopathy.

Abstract
Orthotopic liver transplantation (OLT) is usually associated with significant blood loss and frequently requires the usage of blood products. OLT has been offered sparingly in Jehovah's Witness (JW) patients because of their refusal to accept blood products for religious reasons. Several innovations have made surgery safer in these patients. These include the pre-operative use of erythropoietin to increase red cell mass, the use of intraoperative cell salvage and acute normovolemic hemodilution, and judicious postoperative blood testing. Thoughtful perioperative decision-making and careful surgical techniques remain the cornerstone to a successful outcome. We report our experience in a two-stage hepatectomy done for a JW patient who underwent live donor liver transplant from his mother, also a JW, without blood transfusion. The recipient had an unusually enlarged left lateral segment of the liver which was densely adherent to the spleen. Removing these adhesions in the presence of significant portal hypertension would have resulted in considerable blood loss. This was successfully avoided by leaving this portion of the liver attached to the spleen while proceeding with the hepatectomy. The right lobe of the liver from the donor was then implanted uneventfully. Two weeks later the remaining segment of the recipient liver was removed without incident. The two-stage procedure was life-saving in this JW patient.

Abstract
OBJECTIVE Developing strategies for transfusion-free live donor liver transplantation in Jehovah's Witness patients. SUMMARY BACKGROUND DATA Liver transplantation is the standard of care for patients with end-stage liver disease. A disproportionate increase in transplant candidates and an allocation policy restructuring, favoring patients with advanced disease, have led to longer waiting time and increased medical acuity for transplant recipients. Consequently, Jehovah's Witness patients, who refuse blood product transfusion, are usually excluded from liver transplantation. We combined blood augmentation and conservation practices with live donor liver transplantation (LDLT) to accomplish successful LDLT in Jehovah's Witness patients without blood products. Our algorithm provides broad possibilities for blood conservation for all surgical patients. METHODS From September 1998 until June 2001, 38 LDLTs were performed at Keck USC School of Medicine: 8 in Jehovah's Witness patients (transfusion-free group) and 30 in non-Jehovah's Witness patients (transfusion-eligible group). All transfusion-free patients underwent preoperative blood augmentation with erythropoietin, intraoperative cell salvage, and acute normovolemic hemodilution. These techniques were used in only 7%, 80%, and 10%, respectively, in transfusion-eligible patients. Perioperative clinical data and outcomes were retrospectively reviewed. Data from both groups were statistically analyzed. RESULTS Preoperative liver disease severity was similar in both groups; however, transfusion-free patients had significantly higher hematocrit levels following erythropoietin augmentation. Operative time, blood loss, and postoperative hematocrits were similar in both groups. No blood products were used in transfusion-free patients while 80% of transfusion-eligible patients received a median of 4.5+/- 3.5 units of packed red cell. ICU and total hospital stay were similar in both groups. The survival rate was 100% in transfusion-free patients and 90% in transfusion-eligible patients. CONCLUSIONS Timely LDLT can be done successfully without blood product transfusion in selected patients. Preoperative preparation, intraoperative cell salvage, and acute normovolemic hemodilution are essential. These techniques may be widely applied to all patients for several surgical procedures. Chronic blood product shortages, as well as the known and unknown risk of blood products, should serve as the driving force for development of transfusion-free technology.

Abstract
Obstructive jaundice secondary to common bile duct stricture is most commonly attributed to malignancy. Here we present three unusual cases that mimicked carcinoma in presentation but were histologically diagnosed as benign inflammatory processes during operative care. The first case was attributed to obstruction-induced chronic pancreatitis secondary to Crohn's disease of the head of the pancreas, the second was due to sarcoidosis within periportal and extrahepatic biliary lymph nodes and distal common bile duct, and the third case was due to tuberculosis of biliary lymph nodes. All were successfully managed surgically, but potentially these patients may have been effectively treated pharmacologically, without the need for invasive surgical intervention, if an earlier diagnosis were available to the clinicians. A retrospective and comparative review of the data of each case demonstrated subtle clues such as multiple enlarged biliary lymph node involvement and only moderately elevated bilirubin levels that pointed toward possible nonmalignant processes.

Abstract
Concomitant abdominal aortic aneurysms and cirrhosis that need surgical attention are rare. Currently there are no guidelines with regards to the appropriate timing of the repair of these aneurysms and transplantation. In addition it also raises the issue of which procedure takes precedence. With the advent of endovascular repairs, this issue was resolved with relative ease, by doing the orthotopic liver transplantation (OLT) first and subsequent endovascular stenting on post-operative day 7 during the same hospitalization. This is the first case report of stenting an abdominal aortic aneurysm (AAA) in a liver transplant recipient. The rationale for the OLT and then AAA repair are discussed and formal guidelines are offered.

Abstract
The incidence of splenic artery aneurysm (SAA) in patients with cirrhosis ranges from 7 per cent to 17 per cent. SAA rupture after liver transplantation (LT) is reported to result in significant morbidity and mortality. We report our experience with SAA in LT candidates. From September 1995 through August 2002, 14 LT candidates were diagnosed with SAA. Twenty SAA occurred in 14 patients with an average diameter of 20 mm. Eleven patients qualified for LT; to date, seven have been transplanted. No intervention for SAA occurred prior to LT. Of the seven patients transplanted, four had SAA identified prior to LT. Three were treated at LT and are alive; the fourth had postoperative splenic artery embolization followed by splenectomy and expired on day 109 from duodenal ulcer complications. Three of seven patients had undiagnosed SAA at LT. One required emergency splenectomy for SAA rupture and is alive at 44 months. The remaining two received no treatment; one suffered a late septic death and one is alive at 15 months. No ruptures occurred in our pre-LT population, suggesting that definitive management can await LT. We recommend that all patients undergo four-phase computed tomography or magnetic resonance angiography (MRA) as part of the LT evaluation and that identified SAA be resected at transplantation.

Abstract
Hand-assisted techniques facilitated dissemination of the laparoscopic approach in live kidney donors and addressed concerns regarding potential procedural complications. We report our experience with both standard and hand-assisted laparoscopic nephrectomy in routine, complicated, and higher-risk donors. From July 1999 to September 2002, 47 donors underwent standard laparoscopic donor nephrectomy (SLDN; n = 29) or hand-assisted laparoscopic donor nephrectomy (HALDN; n = 18). Donors were “complicated” if they were >60 years of age, obese, refused blood-product transfusion, had multiple renal arteries or veins, or had right nephrectomies. “Higher-risk” donors had two or more risk factors. Results for SLDN and HALDN were compared for the overall groups and for the “complicated” and “higher-risk” groups. No donor required blood transfusion or reoperation. Warm-ischemia times were shorter in left nephrectomies (191 ± 72 seconds vs. 337 ± 95 seconds, P = 0.005), and blood loss was greater in patients with a body mass index ≥30 kg/m2 (296 ± 232 mL vs. 170 ± 139 mL, P = 0.03).

Abstract
Hand-assisted techniques facilitated dissemination of the laparoscopic approach in live kidney donors and addressed concerns regarding potential procedural complications. We report our experience with both standard and hand-assisted laparoscopic nephrectomy in routine, complicated, and higher-risk donors. From July 1999 to September 2002, 47 donors underwent standard laparoscopic donor nephrectomy (SLDN; n = 29) or hand-assisted laparoscopic donor nephrectomy (HALDN; n = 18). Donors were "complicated" if they were > 60 years of age, obese, refused blood-product transfusion, had multiple renal arteries or veins, or had right nephrectomies. "Higher-risk" donors had two or more risk factors. Results for SLDN and HALDN were compared for the overall groups and for the "complicated" and "higher-risk" groups. No donor required blood transfusion or reoperation. Warm-ischemia times were shorter in left nephrectomies (191 +/- 72 seconds vs. 337 +/- 95 seconds, P = 0.005), and blood loss was greater in patients with a body mass index > or = 30 kg/m2 (296 +/- 232 mL vs. 170 +/- 139 mL, P = 0.03). Higher-risk donors had an increased operative blood loss and longer hospital stay than low-risk donors. Mean donor creatinine at discharge was 1.19 +/- 0.2 mg/dL. Comparison of SLDN versus HALDN revealed shorter operating times for the latter, which approached statistical significance. Warm-ischemia time, operative blood loss, length of hospitalization, and donor and recipient discharge creatinines were similar for both groups. Laparoscopic donor nephrectomy can be applied to selected higher-risk donors with outcomes comparable to uncomplicated donors. Hand-assisted techniques facilitate the procedure during the learning curve, with advantages similar to standard laparoscopic techniques.

Abstract
Increased worldwide travel and immigration have led to an increase in the incidence of hepatic hydatid disease outside of endemic areas. In nonendemic areas lack of familiarity with the disease may lead to a delay in diagnosis with increased risk for development of complicated disease. Complicated disease is defined as: infected cysts, cysts with a hyperechoic solid pattern or calcified walls, or cysts with biliary rupture. Over a 6-month period six patients with complicated hydatid disease were referred to our institution. All six patients were immigrants from endemic areas and were found to have complicated hepatic hydatid disease including cholangitis and intrabiliary rupture. Patients were treated with oral albendazole for 3 weeks before operation and oral praziquantel for 2 days preoperatively. Surgical therapy consisted of subtotal cystectomy, cholecystectomy in all patients, and cystic duct biliary decompression-drainage in five patients. The one patient without biliary drainage developed a postoperative bile leak that resolved with endoscopic biliary stenting. All patients received albendazole for 3 months postoperatively and were free of disease at 6 to 24 months follow-up. We conclude that although nonoperative management with percutaneous drainage or medical management alone may be successful in patients with uncomplicated disease operation remains the therapy of choice for complicated hydatid disease.
