Beliefs of Living Donors About Recipients' End-Stage Liver Failure and Surgery for Organ Donation.

BACKGROUND: The concept of beliefs could provide a basis for how donors may perceive recipients' end-stage liver failure (ESLF) and surgery for organ donation. However, there is no such quantitative study. Therefore, the objective of this study was to explore beliefs of living donors about recipients' ESLF and surgery for organ donation. METHODS: The sample comprised 16 living donors who donated a part of their liver to a patient who had ESLF. The data were analyzed by following established procedures for inductive qualitative analysis. RESULTS: Analysis showed that donors' beliefs can be viewed in a number of groups. Beliefs about recipients' ESLF included diverse explanations for ESLF (blaming oneself and physicians) and physical symptoms (developmental slowing down). Beliefs about being a donor included reasons for being a donor (performing a good deed, being healed), barriers to being a donor (other people being ignorant and selfish), ways to manage these barriers (following one's gut feeling), and factors facilitating being a donor (the feeling that one does not have many people to leave behind). Beliefs about surgery for organ donation included physical effects (pain, feeling stiff). Beliefs about organ donation included views that general organ donation should be encouraged and that people's awareness should be raised. CONCLUSIONS: Existing psychological perspectives could help to interpret some beliefs. Nevertheless, other beliefs, not previously reported, could be considered as targets for individual consultations/psycho-educational programs for fostering emotional well-being.

Liver Transplantation: Recipients' Evaluation of Life From the Perspective of Living Donors.

AIM: Liver transplantation affects not only recipients and living donors' lives, but also the nature and quality of their relationship. Moreover, the ways in which recipients of liver transplant experience life and views of living donors on how recipients experience life may differ. These differences may account for relational changes. It is also important to understand how recipients and their living donors' views differ if the aim is to devise psychoeducational programs for recipients and living donors. Therefore, the present study examined the recipients' experience of life after a diagnosis of end-stage liver failure (ESLF) and transplantation surgery from donors' perspective. METHODS: The sample consisted of 16 living donors who donated a part of their liver to a patient with ESLF. Thematic analysis was undertaken in parallel with interviews during which an interview guide was followed. FINDINGS: Donors felt that recipients evaluated life after the diagnosis of ESLF and transplantation surgery in terms of limitations, mixed relationships, emotional changes, and improvement in life. CONCLUSION: Experience of social limitations, negative emotions, and the feeling that one is supported by others could be interpreted in terms of existing psychological theory. Some ways of adjusting that have not been reported before within the context of ESLF extended the literature. These included others being frightened of being infected by ESLF and being insensitive, experience of positive emotions, and ways of improving. Overall, compared with findings of previous qualitative work among recipients, our findings suggest that donors' evaluation of recipients' lives converge with that of recipients.

Living donor liver transplantation: a life-saving option in emergency situations for diffuse hepatic neuroendocrine tumor metastasis.

Liver metastasis is the main cause of death in patients with gastroenteropancreatic neuroendocrine tumors (GEP-NETs), but only 10%-20% of metastasis in these cases is resectable at the time of diagnosis. In some cases, medical and interventional radiological treatments may not be effective. Liver transplantation, although controversial, may be an option. Worldwide organ-sharing systems do not provide exception points, but give recommendations for liver transplantation in cases of hepatic metastasis from GEP-NETs due to the issue of fair access to donor organs. Living donor liver transplantation is an option in select cases. Presented here are 2 cases in which living donor liver transplantation was performed in emergency situations as a life-saving procedure, with acceptable survival and without donor complications.

Acquired factor XI deficiency: a rare complication after liver transplantation.

BACKGROUND: A majority of coagulation factors are synthesized in the liver. Factor XI (FXI) deficiency (Rosenthal syndrome) is one of the rare inherited coagulation disorders with an extremely low risk of transmission by liver transplantation (LT). CASE REPORT: We report here the case of a 50-year-old man who unknowingly acquired FXI deficiency by LT. During 1 year of post-transplant follow-up, his activated partial thromboplastin time (aPTT) remained prolonged, but he did not develop bleeding complications. The patient required retransplantation due to chronic rejection and is currently doing well 4 years after his first liver transplantation. CONCLUSIONS: The presence of a prolonged aPTT in a deceased donor should raise suspicion for the presence of rare coagulation factor deficiencies. During urgent, lifesaving procedures such as LT, it may be impossible to avoid transmission. Awareness of this possibility will allow early detection and management.

Cadaveric liver transplantation in biliary atresia splenic malformation syndrome with the absence of retrohepatic inferior vena cava, preduodenal portal vein, and intestinal malrotation: a case report.

A 9-month-old female infant with biliary atresia underwent cadaveric liver transplantation due to progressive cholestatic hepatitis following a Kasai operation. She had biliary atresia splenic malformation syndrome (BASM) composed of an absent retrohepatic inferior vena cava with an azygous connection, preduodenal portal vein, polysplenia, and intestinal malrotation. A portal vein thrombosis developed on the 4th postoperative day requiring immediate treatment by thrombectomy. The patient is well with normal liver function at 3 months follow-up. Although BASM may render the transplantation more difficult, the presence of BASM is no longer a contraindication to liver transplantation.

Merkel-cell carcinoma arising after liver transplantation: a case report.

Merkel-cell carcinoma is a rare and an aggressive neuroendocrine tumour of the skin that has been reported to be common in transplant recipients. Herein, a 25-year-old woman who developed Merkel-cell carcinoma after liver transplantation is reported.

False aneurysm of the hepatic artery after laparoscopic cholecystectomy.

PURPOSE: A rare complication of laparoscopic cholecystectomy is defined: iatrogenic injuries to hepatic artery system which may evolve to pseudoaneurysms in the late postoperative period. This rare phenomenon may be overlooked and pose a challenge to surgeons. MATERIAL AND METHODS: We will describe three cases with iatrogenic pseudoaneurysms after laparoscopic cholecystectomy. The onset of symptoms and the course of the disease was not uniform. Diagnosis was made after a considerable delay. In the first case, a small, uncomplicated extrahepatic pseudoaneurysm was successfully treated with coil embolization. The second patient who had an intrahepatic pseudoaneurysm with multiple injuries to the common bile duct and portal vein, did not survive despite surgical and endovascular interventions. In the latter, surgical treatment for a large pseudoaneurysm that had ruptured into the liver parenchyma was successfully conducted. Review of the literature reveals fifty-four more cholecystectomy-related pseudoaneurysms. The site of injury was the right hepatic artery in 61% of the cases and the presenting symptom was upper gastrointestinal bleeding (haemobilia) in two-third of the patients. Embolization was performed in 82% of the cases, and surgery was undertaken in the remaining 18%. CONCLUSION: Pseudoaneurysm is an uncommon complication of laparoscopic cholecystectomy. Prompt attention is necessary since the lesion has a high risk of rupture. Embolization is the first line of treatment and surgery is reserved for more complex injuries and cases with life-threatening rupture of the aneurysm.

Long-term results of surgery for liver hemangiomas.

BACKGROUND: Elective surgery for liver hemangiomas is still controversial. HYPOTHESIS: Long-term results show that elective surgery for liver hemangiomas is safe and effective. SETTING: A tertiary care university hospital in Istanbul, Turkey. PATIENTS: Forty-two patients underwent surgery for liver hemangiomas between January 1988 and December 1998; 41 were symptomatic. The primary indications for surgery were abdominal pain in 33 patients, diagnostic uncertainty in 6, and enlargement in 3. The median largest dimension of the major lesion was 10 cm (range, 7-45 cm). MAIN OUTCOME MEASURES: (1) Patients' assessment of the effects of surgery on preoperative symptoms, (2) determination of whether any other pathological conditions were missed in the preoperative evaluation, (3) operative mortality and morbidity, and (4) recurrences. DESIGN: Retrospective cohort study. RESULTS: Enucleation was the most frequent operation (33 patients). Hospital mortality and morbidity were 2.4% (bleeding from the biopsy site on a lesion evaluated as inoperable at laparotomy; 1 patient) and 12% (5 patients), respectively. Thirty-three patients could be followed up for a median of 53 months (range, 6-135 months). Of the 32 preoperatively symptomatic patients, surgery was successful in symptom control in 28 (88%) (complete resolution or significant amelioration). No other cause of pain could be identified during follow-up in the other patients. Control ultrasonography revealed no recurrences. CONCLUSIONS: Elective surgery is indicated in a small subset of patients with hemangiomas because of abdominal pain, enlargement, and diagnostic uncertainty. The results of surgery in symptom control are gratifying in approximately 90% of patients. Recurrences are rare. Enucleation can be performed rapidly and safely in most patients and should be preferred to resection.

Mesoatrial shunt in Budd-Chiari syndrome.

BACKGROUND: The operations with proven effects on survival in Budd-Chiari syndrome are shunt operations and liver transplantation. PATIENTS AND METHODS: Between 1993 and 1999 (June), 13 cases of Budd-Chiari syndrome have been treated surgically. Four cases had concomitant thrombosis of the inferior vena cava; the others had marked narrowing of the lumen due to the enlarged caudate lobe. Mesoatrial (n = 12) or mesosuperior vena caval (n = 1) shunts were constructed with ringed polytetrafluoroethylene grafts. RESULTS: The median portal pressure fell from 45 (range 32 to 55) to 20 (range 11 to 27) cm H(2)O (P <0.001). Two patients died in the early postoperative period. One patient who did not comply with anticoagulant treatment had a shunt thrombosis in the second postoperative year. The other 10 patients are alive without problems during a median 42 (range 1 to 76) months of follow-up. CONCLUSION: Mesoatrial shunt with a ringed polytetrafluoroethylene graft is effective in Budd-Chiari syndrome cases with thrombosis or significant stenosis in the inferior vena cava.

Primary lymphoma of the liver: report of a case.

We describe herein a female patient with non-Hodgkin's lymphoma of the liver and present a review of the related literature. The patient was referred with the diagnosis of malignant hemangiopericytoma (with an open biopsy). The physical examination, standard laboratory test results and tumor marker levels were all normal. A nonstandard left lobectomy was performed. Histopathological and immunohistochemical examinations revealed non-Hodgkin's lymphoma of B-cell type. The findings of a peripheral blood smear and bone marrow biopsy were normal. There was no other site of involvement based on physical or radiological examinations. These findings established the diagnosis of primary hepatic lymphoma. Fewer than 100 cases have been reported in the world literature. The best treatment results have been obtained by a resection followed by chemotherapy when feasible.

Phantom steatosis of the liver: report of a case.

A patient, referred under a diagnosis of metastatic liver tumors, was found to have multiple areas of focal fatty change (FFC) which, during follow-up, exhibited discordant evolutions. To our knowledge, this phenomenon-regression of a FFC lesion with concurrent appearance or progression of other similar lesions in the same patient, has been reported in only one previous case. FFC can be strongly suggested by clinical, biochemical and radiologic criteria. However, an exact diagnosis can only be made with biopsy. To avoid misdiagnosing a malignancy as FFC and vice versa, biopsy should be performed without hesitation in all patients in whom a change in approach is possible.

Elective repair of abdominal wall hernias in decompensated cirrhosis.

BACKGROUND/AIMS: Abdominal wall hernia is a common feature of decompensated cirrhosis. However, literature on elective hernia repair in these patients is limited. Here we report the experience of our center. METHODOLOGY: Eleven hernias (seven umbilical, three inguinal and one incisional) in nine patients with decompensated cirrhosis were repaired. The indication for operation was repeated incarceration in two patients and significant pain in four; three patients with umbilical hernias had ulceration and necrosis of the overlying skin. Pre-operatively, medical therapy of ascites was conducted at the hepatology unit. Umbilical hernias were treated with the classic Mayo repair; in all cases but two, this was buttressed with a prolene graft. One inguinal hernia was repaired with the plication-darn technique; the other two and the incisional hernia were repaired with prolene grafts. RESULTS: There was no mortality. One patient had a scrotal hematoma; two patients had leakage of ascites into the wound. Seven patients were followed up. Four patients died without recurrence after a median period of 12 months (range 6-22). The other patients have no recurrence at 1, 10 and 40 months post-operatively. CONCLUSIONS: Umbilical and inguinal hernias in patients with decompensated cirrhosis may be repaired safely on an elective basis. Control of ascites is vital for success.

Endoscopic sphincterotomy in the treatment of postoperative biliary fistulas of hepatic hydatid disease.

BACKGROUND: Ten patients with postoperative external biliary fistula treated by endoscopic sphincterotomy are reported. METHODS: Nine of these patients were operated for hepatic hydatid disease and one for a liver abscess. Mean daily output of bile through the fistulae which were present for 5-39 days was approximately 500 cc. RESULTS: Treatment was successful in nine patients with closure of the fistulae in 2-15 days (mean, 7 days). No response was obtained in one patient who was reoperated, and an intrahepatic biliary duct was found to be completely eroded by the cyst wall. CONCLUSIONS: Endoscopic sphincterotomy should be the first-line treatment for postoperative external biliary fistulae related to hepatic hydatid disease.

Laparoscopic treatment of hepatic hydatid disease.

Surgery is still the main modality in the treatment of hepatic hydatid disease. Laparoscopic methods, with their low morbidity, have gained prominence in many fields and, in some cases, have nearly replaced open surgery. In this report, a laparoscopic method for the treatment of hepatic hydatid disease is described and the results in the first six cases are presented. The method involves the use of an aspirator-grinder apparatus designed specifically for laparoscopic surgery. The postoperative courses of the patients were very comfortable and no complication related to the laparoscopic technique occurred. The method achieves evacuation of all viable cyst contents with the patient benefits of laparoscopic surgery. The apparatus practically eliminates the risk of spillage. The postoperative parameters and the early follow-up results (21-27 months) are very encouraging.

Liver hamartoma in an adult: report of a rare case.

Liver hamartoma is a rare type of benign tumor which usually occurs in the first few years of life. Although it is the second most common benign tumor in childhood, only about 100 cases have been reported in the English literature. Thus, it is extremely rare to encounter liver hamartoma in adults. This report details the clinical presentation and surgical management of a 24-year-old woman with a rapidly growing liver hamartoma. A right hepatic lobectomy was successfully performed and the patient was discharged in good health on the 10th postoperative day.

Laparoscopic surgery of hepatic hydatid disease: initial results and early follow-up of 16 patients.

Surgery is the main modality in the treatment of hepatic hydatid disease. In this report, a laparoscopic surgical method is described, and the results in the first 16 cases are presented. The method involves the use of an aspirator-grinder apparatus that achieves effective evacuation of viable cyst contents with the patient benefiting from the laparoscopic approach. Cavity infection occurred in two patients and was treated conservatively. In another patient, postoperative ultrasonography revealed a thick-walled cavity containing a dense fluid. Because the patient was symptomatic, pericystectomy was performed during the sixth postoperative month. Early postoperative parameters and the early follow-up results in other patients (2-17 months) are encouraging. The method is particularly suitable for uncomplicated, early-stage cysts located in laparoscopically accessible locations.

N-acetylcysteine ameliorates reperfusion injury after warm hepatic ischemia.

Glutathione is important in cellular defense against oxidative stress. We postulated that administration of N-acetylcysteine (NAC), a glutathione precursor, might help maintain or replenish hepatic glutathione stores, thereby reducing reperfusion injury in liver grafts after warm ischemia. Eighteen pigs were subjected to 2 hr of warm hepatic ischemia and divided into a control group (group A, n = 6), a preischemia treatment group (group B, n = 6: NAC, 150 mg/kg, continuous i.v. infusion 1 hr before ischemia), and a postischemia treatment group (group C, n = 6: NAC, 150 mg/kg continuous i.v., begun 20 min before reperfusion and continued for 1 hr). At initiation of laparotomy, we measured hepatic levels of reduced glutathione (GSH), its oxidized form (GSSG), ATP, aspartate aminotransferase (AST), and lactate dehydrogenase (LDH). Before reperfusion, after 2 hr of warm ischemia, GSH, GSSG, and ATP were measured. One hour after reperfusion, we measured GSH, GSSG, ATP, AST, and LDH. Bile output was recorded every 10 min. Postoperfusion AST and LDH were significantly lower in both treatment groups than in controls. In group B, hepatic glutathione was maintained at significantly higher levels than in controls, even after ischemia (P < 0.05). In group C, although hepatic GSH levels fell until reperfusion, after administration of NAC, hepatic GSH reached the level of the preischemia treatment group. In both treatment groups, GSH 1 hr after reperfusion was significantly higher than in the controls (P < 0.01): regeneration of glutathione was seen in all 6 animals in group C, compared with 2/6 in group B and none in the control group. ATP recovery, bile output, and survival were all better in the treatment groups than in the control group. Pretreatment with NAC helps maintain hepatic glutathione during warm ischemia; given after ischemia, NAC is effective in replenishing depleted glutathione stores. Adjunctive use of NAC was associated with improved glutathione homeostasis, improved bile output and ATP regeneration, and increased survival.

Papillary adenocarcinoma of the common bile duct.

Five patients with papillary adenocarcinoma of the common bile duct (CBD) are described. These are rare tumors and make up 5% of all malignant tumors of the biliary tract. The symptoms and signs at the time of initial diagnosis resemble benign obstructive lesions of the bile ducts. The tumor is soft, less invasive to adjacent tissues and tends to grow into the lumen. The early onset of the symptoms results in early intervention, with a better prognosis. Two of our patients are doing well after two and four years, where as three others were readmitted with recurrent disease.

Flushing with autologous blood improves intraoperative hemodynamic stability and early graft function in clinical hepatic transplantation.

Hemodynamic instability and hyperkalemia are common after reperfusion and may cause ischemic damage on the hepatic allograft. Two techniques for flushing hepatic grafts before reperfusion were studied to evaluate their effects on intraoperative hemodynamic and metabolic status and on early graft function in 83 consecutive adult hepatic transplantations. In the first 41 patients (group 1), the hepatic grafts were rinsed with 500 milliliters of lactated Ringer's solution (LR). In the subsequent 42 patients (group 2), in addition to LR rinse, the first 500 milliliters of portal blood to flush and reperfuse the liver were drained through the cannula inserted into the donor vena cava before unclamping the vena cava. After reperfusion, the mean arterial pressure decreased 30 +/- 4 percent in group 1 versus 17 +/- 2 percent in group 2 (p < 0.02), and serum K+ increased by 1.9 +/- 0.2 in group 1 versus 0.8 +/- 0.2 milliequivalents per liter in group 2 (p < 0.01). Hyperkalemic cardiac arrest was only seen in two patients in group 1. The K+ concentration in the first 100 milliliters of discarded blood was found to be 40 +/- 2 milliequivalents per liter. The 500 milliliters of discarded blood contained 8.3 +/- 0.4 milliequivalents, which was correlated with graft liver weight (p < 0.001). Early graft function, as measured by serum glutamic-oxaloacetic transaminase, serum glutamic pyruvic transaminase, total bilirubin and prothrombin time on postoperative day No. 2, was significantly better in group 2 than in group 1 (p < 0.05). The six-month graft and patient survival rates in group 1 were 66 and 75 percent, versus 90 and 95 percent in group 2 (p < 0.01 and p < 0.02, respectively). Further flushing with 500 milliliters of autologous portal blood resulted in smaller intraoperative shifts in serum K+, greater hemodynamic stability, better graft function and improved graft and patient survival.
