- Neuroendocrine (NE) tumours of the gastrointestinal tract (carcinoids and endocrine pancreatic tumours) are rare diseases. In the presence of liver metastases these patients may suffer from disabling symptoms due to hormone overproduction. Patients with localized disease can be resected for cure and also patients with liver metastases can undergo potentially curative tumour resection. However, long-term follow-up of the latter cases indicates frequent recurrence of tumour. Using close biochemical monitoring of tumour markers combined with newer techniques for tumour visualization, these recurrences can often be diagnosed at an early stage so that repeat surgical procedures can be performed. During the last years very active surgery has been recommended for NE tumours, many of which have a relatively slow growth. Even in patients not amenable to curative liver surgery, debulking can be considered if the main tumour burden can be safely excised. The primary aim of this type of treatment is palliation of hormonal symptoms. An important question is whether the aggressive treatment actually prolongs survival. No prospective studies have been performed. Such studies are hampered by the lack of strict surgical programs running over long periods and the relative rarity of NE tumours. Liver transplantation may be another treatment modality in selected cases.

- Liver metastases imply a major problem in patients with carcinoid tumours and hormone overproduction. Patients with distant metastases can undergo resection for potential cure or for symptom palliation. In patients with bilobar liver metastases other interventions are at hand, e.g. local ablation or hepatic arterial embolization. In selected cases liver transplantation can be a treatment alternative. Prior to all interventions patients with midgut carcinoids are protected with somatostatin analogues to reduce hormone secretion. Patients with foregut carcinoids may present special problems with life-threatening release of histamine during interventions.

Liver transplantation for treatment of metastatic neuroendocrine tumors
- 2004
-
Ingår i: Annals of the New York Academy of Sciences. - 0077-8923. ; 1014, s. 265-9
-
Tidskriftsartikel (refereegranskat)abstract
- Liver transplantation can be considered a therapeutic option for patients with neuroendocrine tumors only metastatic to the liver. Important selection criteria are well-differentiated tumors and a low proliferation rate (Ki67 <10%). In this series, orthopic liver transplantation offered good relief of symptoms and long disease-free intervals with initial survival of grafts and patients as in benign disease. The experience with multivisceral transplantation is still limited.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND/AIMS: Hepatobiliary malignancies are frequently seen in primary sclerosing cholangitis (PSC) and they complicate the evaluation of patients and timing of liver transplantation. METHODS: Data from all Nordic PSC patients listed for liver transplantation during 1990-2001 were recorded prospectively. Predictors of hepatobiliary malignancy and patient survival rates have been analysed. RESULTS: Hepatobiliary malignancy was found in 52/255 (20%) patients accepted to the waiting list. Recent diagnosis of PSC, no ursodeoxycholic acid (UDCA) treatment, clinical suspicion and previous colorectal-cancer were predictors of malignancy. Among 89 patients with a strong suspicion of malignancy prior to acceptance, 35 (39%) had confirmed malignancy. A clinical suspicion had been raised in 35/52 (67%) patients with malignancy. Malignancy was found in 31/223 patients who received a liver allograft. The 1-, 3- and 5-year patient survival rates following transplantation for patients with PSC and cholangiocarcinoma were 65, 35 and 35%, respectively. CONCLUSIONS: Hepatobiliary malignancy is suspected in 1/3 of the PSC patients and found in 1/5. Although cholangiocarcinoma is regarded as a contraindication to liver transplantation (LTX), PSC patients with cholangiocarcinoma had a 35% 5-year survival following transplantation.

The essence of living parental liver donation--donors' lived experiences of donation to their children.

- The use of living parental liver donors will continue and probably increase because of lack of cadaveric livers for paediatric transplantation and the excellent graft survival of parental livers. Therefore, it is important for the health care professionals involved in living parental liver donation to understand the experience of being a liver donor. The aim of this study was to investigate the expressed deeper feelings of parents who donated a part of their liver to their own child. The study took the form of in-depth interviews with 11 donors. All donors were biological parents of the recipient, nine fathers and two mothers. The interpretive phenomenology method was used, and interpretive analysis was carried out in three interrelated processes in line with Benner. Data collection was guided by the researcher's preliminary understanding of the donor experience from being involved in the surgery and care of the donors as well as the paediatric recipients. However, the research question was approached from the perspective of holistic care for the donor. In this study, the essence of living parental liver donation was found to be the struggle for holistic confirmation. There were three categories leading to this central theme; the total lack of choice, facing the fear of death and the transition from health to illness. There was total agreement among the respondents that there is no choice when it comes to the question of donation. The findings in this study stress the importance of organizing the parental liver donation programme with as much focus on the donor as on the child. Based on the results of this study, several clinical implications are suggested for the formation of guidelines for living parental liver donation.

- Outcome after intestinal transplantation has improved dramatically since the introduction of novel immunosuppressive agents and refined surgical techniques. Small bowel transplantation is now considered to be the best treatment modality for patients with life threatening complications of intestinal failure and parenteral nutrition. We hereby review the international experience as well as the first ten cases of intestinal transplantation performed in Sweden.

Laparoscopic or open surgery for living donor nephrectomy factor for graft loss
- 2001
-
Ingår i: Nephrology Dialysis and Transplantation. - 1460-2385. ; 16:2, s. 383-6

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: The anterior extraperitoneal approach for living donor nephrectomy has been used in more than 700 living cases in the unit and proved to be safe for the donor. In 1998, laparoscopic nephrectomy was introduced as an option when technically feasible. We found it essential to investigate the consequences of the new technique. SUBJECTS AND METHODS: One hundred living donor kidney transplantations were performed from 1998 to June 2000, 45 with laparoscopic, 55 with open nephrectomy. The donors took part in a structured interview 4 weeks after the donation and their responses were categorized in three classes. RESULTS: In each group, one recipient had delayed initial function. The serum creatinine levels after 3 and 7 days or the GFR values after 6 months did not differ. One graft has been lost following laparoscopic nephrectomy and four after open surgery. For the laparoscopy donors, the median number of post-operative days in hospital was 5.0 days (range 2-9), vs 6.0 (4-8) after open surgery (NS). The requirement of opoid analgesics post-operatively was 5.0 doses (1-22) vs 6.0 (1-38) (P=0.02); and after 4 weeks, 23 of 45 laparoscopic donors were free of pain vs eight of 55 open nephrectomy donors (P=0.0004). Approximately one-third of all donors felt some restriction of physical activity and the majority complained of impaired physical energy. There were no differences between the groups. The duration of sick-leave after laparoscopic surgery was median 6 (2-19) weeks vs 7 (1-16) (NS). CONCLUSIONS: Laparoscopic nephrectomy is safe. Less post-operative pain is a definite advantage for the donor. PMID: 11158417 [PubMed - indexed for MEDLINE]

Oral administration of xenogeneic erythrocytes induces production of antibodies that are capable of inducing hyperacute rejection of concordant vascularized xenografts
- 2004

Ingår i: Transplantation. - 0041-1337. ; 77:7, s. 1100-3

Tidskriftsartikel (refereegranskat)abstract
- Oral tolerance induction has proven to be an effective approach for inducing antigen-specific unresponsiveness in several models for allogeneic transplantation and autoimmune diseases. The authors' preliminary studies, however, indicated that xenospecific antibodies are produced when rats are given mouse erythrocytes orally. This response was further examined. Mouse erythrocytes were administered to rats orally or intravenously during one or two episodes, and sera were obtained on day 9 or day 29, respectively. Rat sera containing a positive hemagglutinating titer against mouse antigens were injected into rats that had recently undergone xenotransplantation to study graft survival. Oral administration of xenogeneic cells induced a powerful antibody response consisting mainly of xenospecific immunoglobulin (Ig) M and IgG. This antibody response also induced hyperacute rejection as powerfully as sera from intravenously immunized rats. The authors' study thus indicates that oral administration of xenogeneic cells is a powerful immunization pathway that induces an antibody response capable of rejecting concordant vascularized xenografts.
