An arteriovenous malformation associated ischemic colitis in the setting of acute gastrointestinal clostridium difficile colitis and intestinal amebiasis: A case report.

BACKGROUND: There is one reported case of inferior mesenteric arteriovenous malformation presenting as ischemic colitis after an episode of gastrointestinal infection. We documented this case to emphasize the possible association between ischemic colitis and vascular malformations. In addition, this is the number 15th case in the literature about this association. CASE SUMMARY: A 40 years old male patient presented with abdominal pain and diarrhea of 10 days duration after he was diagnosed and managed as a case of Clostridium Difficile infection and amebiasis. Computed tomography angiography revealed a vascular malformation of the inferior mesenteric artery, repeated colonoscopy showed ulceration and sloughing of the mucosa, he underwent Hartmann's procedure due to colonic ischemia diagnosed by the previous measures. Later on he had a colostomy closure and end to end colorectal anastomosis. CONCLUSION: There is a possible association between acute gastrointestinal infection and ischemic colitis in the setting of arteriovenous malformation.

Mapping the global research landscape on nutritional support for patients with gastrointestinal malignancy: visualization analysis.

BACKGROUND: Early nutritional treatment is crucial for the care of patients with operable and advanced gastrointestinal malignancies. Therefore, much research has focused on nutritional support for patients with gastrointestinal malignancies. Therefore, this study aimed to evaluate the global scientific output and activity with respect to nutritional support and gastrointestinal malignancy. METHODS: We searched in Scopus for publications on gastrointestinal cancer and nutritional assistance published between January 2002 and December 2021. Then, using VOSviewer 1.6.18 and Microsoft Excel 2013, we conducted bibliometric analysis and visualization. RESULTS: A total of 906 documents were published between 2002 and 2021, including 740 original articles (81.68%) and 107 reviews (11.81%). China ranked first (298 publications, 32.89%), Japan ranked second (86 publications, 9.49%) and the USA ranked third (84 publications, 9.27%). The organisation with the highest number of publications was the Chinese Academy of Medical Sciences & Peking Union Medical College from China, with 14 articles, followed by the Peking Union Medical College Hospital from China and the Hospital Universitari Vall d'Hebron from Spain (13 publications for each). Before 2016, most studies focused on 'nutrition support for patients undergoing gastrointestinal surgery'. However, the latest trends showed that 'nutrition support and clinical outcomes in gastrointestinal malignancies' and 'malnutrition in patients with gastrointestinal cancer' would be more widespread in the future. CONCLUSIONS: This review is the first bibliometric study to provide a thorough and scientific analysis of gastrointestinal cancer and nutritional support trends worldwide over the last 20 years. This study can aid researchers in decision-making by helping them understand the frontiers and hotspots in nutrition support and gastrointestinal cancer research. Future institutional and international collaboration is expected to accelerate the advancement of gastrointestinal cancer and nutritional support research and investigate more efficient treatment methods.

Knowledge levels, attitudes, and awareness of nurses toward organ donation.

OBJECTIVE: The aim of this study was to assess the knowledge, attitudes, and practices of nurses in Turkiye concerning organ donation. METHODS: This survey-based, descriptive cross-sectional study was conducted from January 2020 to March 2020, recruiting 560 of 850 nurses currently working in a tertiary university hospital with a face-to-face interview technique. The questionnaire consisted of 35 questions evaluating sociodemographic features, organ donation knowledge level, attitude, and nurses' awareness. RESULTS: This study showed that only 6.5% of the nurses donated their organs. While 31.9% stated that they are willing to consider organ donation in the future, 41.3% were not decided about organ donation yet, and 27% rejected organ donation in any condition. Among the nurses who refused organ donation, 69.6% had no specific reason and 10.6% worried that their organs might be taken without proper diagnosis of brain death. About 10% denied organ donation for religious beliefs, and 5% were because of concerns about body integrity. Hesitation about procuring organs for commercial purposes was present in 7.2% of the nurses. Following a possible diagnosis of brain death of a relative, 33.8% of the nurses said that they would consent for organ donation to him/her, whereas 47.1% were not sure about this issue. Among the nurses, 76.6% agreed on a possible living-related organ donor for a close relative, 53.3% accepted receiving an organ from a close relative if required. Furthermore, this investigation showed that nurses who reported attending previous seminars, conferences, or training programs about organ donation have significantly better donation rates and stronger attitudes toward organ donation. Nurses who donated their organs are found to know better about brain death irreversibility, understand better the related national legal regulations for organ donation, and are more informed about the compatibility of organ donation with religious beliefs. CONCLUSION: This study showed that nurses have a relatively positive attitude toward donation and transplantation but are unwilling to bequeath their organs. This study underlines the indispensable contribution of nurses promoting organ donation and highlights the need for well-structured educational programs to enhance their role in organ donation and transplantation.

Tissue Heavy Metals in Liver Diseases.

BACKGROUND: Our objective was to determine the levels of heavy metals, oxidants, and antioxidants in liver tissue of patients with chronic liver disease (CLD) compared with healthy living liver donors (LLDs). METHODS: We obtained liver specimens from patients undergoing liver transplant for CLD. Samples were also obtained from LLDs. Biochemical analyses were performed on all samples, and the levels of liver tissue, heavy metal, and oxidant-antioxidants biomarker levels in patients with CLD were compared with those measured in LLDs. RESULTS: One hundred and eighteen individuals were included for analyses. Fifty-nine were patients with CLD, and 59 were LLDs. The median levels of liver tissue of superoxide dismutase (P = .009), glutathione peroxidase (P = .042), total oxidant status (P = .006), oxidative stress index (P < .001), and copper (P = .035) were prominently more elevated in CLD than LLDs. On the other hand, the median levels of liver tissue of cadmium (P < .001), selenium (P = .042), and zinc (P < .001) levels were more elevated in the LLDs than patients with CLD. The 2 groups were similar in terms of total antioxidant status, manganese, arsenic, and lead levels. CONCLUSIONS: Superoxide accumulation in the liver was higher in patients with CLD. Concerning heavy metals, only the median tissue copper was elevated in patients with CLD with higher Cu/Zn ratio. Cadmium, selenium, and zinc were significantly higher in the healthy LLDs.

Coexistence of tuberculosis and extranodal marginal zone lymphoma of the thyroid gland: Case report and literature review.

Introduction: Primary thyroid tuberculosis (TB) is rare even in countries where TB disease is endemic, with the prevalence ranging from 0.1 to 1.15%. Primary thyroid lymphoma is uncommon, and the majority of lymphomas arising in the thyroid gland are non-Hodgkin's lymphomas of B-cell origin, of which about 25% is extranodal marginal zone B cell lymphoma (MALToma). Case presentation: An 86-year- old Turkish female patient with thyroid nodules and cervical lymphadenopathies presented with large multinodular goiter and compressive symptoms. Total thyroidectomy and central lymph node dissection were performed. The revised histological and immunohistochemical revealed the coexistence of thyroid TB and MALToma. The patient received an anti-TB treatment for six months before a revised histopathological examination. About seven months after anti-TB treatment, the patient died due to an unknown cause. Clinical discussion: Although six cases of thyroid TB and papillary thyroid cancer have been documented in the medical literature, no cases of TB and MALToma coexistence have been published so far, to our knowledge. Another essential feature of this study is that the initial pathological examination was reported as thyroid TB. A subsequent re-examination revealed that the patient had both TB and MALT lymphoma. Conclusion: We discuss this rare association and the dilemma encountered in the diagnosis and management of this patient with a review of the literature.

Medical students' knowledge, attitudes and awareness toward organ donation.

OBJECTIVE: This survey study aimed to evaluate medical students' attitudes, knowledge, and awareness toward organ donation. METHODS: For this questionnaire-based cross-sectional study, 1000 medical students were interviewed, out of which 950 students agreed to participate in the study and were enrolled. A questionnaire form consisting of 29 questions was used to determine the students' socio-demographic characteristics and rate their knowledge, attitudes, and behaviors about organ donation. RESULTS: While 95.5% (n = 907) of the students stated that they had not donated organs, 41.1% stated that they had not yet decided to donate organs, and 59.7% stated that they had no specific reason for them not donating organs. Out of the participants, 68.1% stated that organ donation complies with the Islamic rules; 40.7% stated that the Directorate of Religious Affairs issued a fatwa on organ donation, and 39.4% stated that there are legal regulations on organ donation in the country. While 22.1% of the students stated that a person with brain death could come back to life, 19.7% stated that they did not know about this issue. The students who had donated organs and who did not show significant differences regarding the answers given to the questions about whether organ donation complies with religious rules (p < 0.001), where one must apply to donate organs (p = 0.032), the will to donate the organs of a relative with brain death (p = 0.004), and whether preaching in mosques and foundations is needed to increase organ donation rates (p = 0.042). Although there was a correlation between the students' grade and their attitude and knowledge about organ donation, this correlation was weak and showed no parallelism with increasing grades. CONCLUSION: This study indicates that medical students have inadequate knowledge, attitudes, and behaviors about organ donation. In our opinion, it is of paramount importance to provide physician candidates, who should set an example for society, with periodic training on organ donation throughout their academic life in shaping the national organ donation policy in the future.

Assessment of Knowledge and Attitudes Toward Organ Donation Among School Teachers: First National Survey Study.

BACKGROUND AND AIM: The most important factors affecting organ donation are socioeconomic, educational, and cultural factors. The aim of this study was to evaluate the attitudes, knowledge levels, and behaviors of school teachers toward organ donation METHODS: This study surveyed 2400 school teachers working in official public schools. Turkey was divided into 26 regions based on the similarity of social, economic, and geographic factors identified by the Turkish Statistical Institute. Teachers were distributed equally in the city center and towns based on population. The survey procedures were carried out using computer-assisted personal interviewing. RESULTS: Among teachers, 89.6% had a bachelor's degree and 8.5% had a master's degree. In addition, 32.5% worked in primary schools, 33.1% worked in secondary schools, and 34.4% worked in high schools. Furthermore, 0.7% had donated an organ; 66.5% were not considering organ donation in the future, of whom 9.0% indicated religion as the reason for not donating an organ, and 34.8% did not indicate any reason. In addition, 96.6% considered organ donation to be proper behavior for humanity and 68% believed that organ donation is appropriate in religious terms. CONCLUSIONS: This study showed that school teachers have inadequate knowledge and attitudes toward organ donation. Encouraging children and adolescents to make a well-informed decision about organ donation and to register this choice will depend largely on preparing school teachers with adequate knowledge and motivation toward creating generations with a positive attitude toward organ donation.

Dismembered pyeloplasty for post-traumatic ureteropelvic junction avulsion in a child.

Non - iatrogenic ureteral injury is rare because of the well-protected retroperitoneal location of the ureter with an incidence of less than 1%. Furthermore, isolated ureteropelvic junction (UPJ) avulsion as a result of acceleration/deceleration injury is extremely uncommon and may lead to significant morbidity if the diagnosis has not been made early using CT scan with delayed execratory phase. Endourological management of partial ureteric injuries is feasible, however, uretero-ureterostomy is the standard of care for complete upper ureteric injuries. We present a fourteen years old boy presented with UPJ avulsion secondary to blunt trauma treated with dismembered pyeloplasty approach.

An investigation into the factors predicting acute appendicitis and perforated appendicitis.

BACKGROUND: To investigate the factors predicting acute appendicitis (AAp) and perforated AAp in patients who underwent surgery with a preliminary diagnosis of AAp. METHODS: Between May 2009 and December 2018, 1316 patients underwent appendectomy with a presumed diagnosis of AAp. To investigate the factors predicting AAp, patients were divided into two groups considering the histopathological presence of inflammatory changes in the appendix: AAp positive (AAp group; n=1043) and AAp negative (Non-AAp group; n=273). Also, to investigate the factors predicting appendiceal perforation, patients with AAp were divided into two groups considering the presence of perforation: non-perforated AAp (n=850) and perforated AAp (n=193). ROC curve analysis was used to identify optimum cut-off values of quantitative variables. The groups were compared using univariate analysis methods and parameters with a p≤ 0.20 were taken into a multivariate logistic regression model. RESULTS: Multivariate analysis method related to factors predicting AAp showed that gender (male; p=0.034; OR=1.4), WBC (≥10.900; p=0.022; OR=1.5), MPV (≥29.1; p=0.006; OR=1.6), TBil (≥0.61; p=0.034; OR=1.4), CRP (≥0.725; p=0.002; OR=1.7), NLR (≥5.13; p=0.034; OR=1.5), PNR (<24.04; p=0.001; OR=1.9) and US findings (AAp+; p<0.001; OR=2.9) were independent factors for predicting AAp. Multivariate analysis method related to factors predicting appendiceal perforation showed that age (≥32 years; p<0.001; OR=2.5), TBil (≥0.67; p=0.046; OR=1.5), CRP (≥3.75; p<0.001; OR=3.0) and NLR (≥5.69; p=0.006; OR=1.8) were independent factors for predicting perforated AAp. CONCLUSION: We believe that predicting both AAp and perforation will help the clinician evaluate patients who applied to the emergency unit with presumed diagnosis AAp. This approach will also contribute to reducing the negative appendectomy and perforation rates.

Analysis of risk factors affecting the development of peptic ulcer perforation: case-control study.

AIM: The aim of the to determine the risk factors associated with increased risk of peptic ulcer perforation (PUP). MATERIAL AND METHODS: The demographic, clinic, and biochemical parameters of 65 patients (PUP group) who underwent PUP surgery at our clinic between June 2009 and September 2016 were compared with the data of 134 patients (control group) who underwent endoscopy at a gastroenterology clinic for dyspeptic complaints. The control group were matched at random in a 1 : 2 ratio with the PUP group. Univariate analyses were used to compare different variables and variables with clinical significance, and p ≤ 0.05 was used in the backward stepwise logistic regression model. RESULTS: This study included 65 patients with peptic ulcer perforation aged 17 to 92 years (PUP group) and 134 patients with dyspeptic complaints aged 18 to 87 years (control group). Univariate analysis showed that statistically significant differences were found between groups in terms of non-steroidal anti-inflammatory drugs usage (p = 0.042; OR = 1.868), smoking (p < 0.001; OR = 5.124), old age (p = 0.003), low body mass index (BMI) (p < 0.001), and low hemoglobin (Hb) (p = 0.002). However multivariate analysis showed that increasing age (p = 0.004; OR = 1.035), smoking (p = 0.007; OR = 3.591), decreasing Hb (p = 0.042; OR = 1.277), and decreasing BMI (p < 0.001; OR = 1.669) were independent clinically significant risk factors for development of PUP. CONCLUSIONS: This study showed that decreased BMI, decreased Hb, increased age, and smoking were independent risk factors for development of PUP. Thus, this group of patients needs particular attention paid to suggestive symptoms with early diagnosis and optimal management of peptic ulcer disease.

Xanthogranulomatous appendicitis: A comprehensive literature review.

BACKGROUND: Xanthogranulomatous inflammation is characterized histologically by a collection of lipid-laden macrophages admixed with lymphocytes, plasma cells, neutrophils, and often multinucleated giant cells with or without cholesterol clefts. AIM: To review the medical literature on xanthogranulomatous appendicitis (XGA). METHODS: We present a patient with XGA and review published articles on XGA accessed via the PubMed, MEDLINE, Google Scholar, and Google databases. Keywords used were "appendix vermiformis," "appendectomy," "acute appendicitis," and "XGA." The search included articles published before May 2020, and the publication language was not restricted. The search included letters to the editor, case reports, review articles, original articles, and meeting presentations. Articles or abstracts containing adequate information about age, sex, clinical presentation, white blood cells, initial diagnosis, surgical approach, histopathological and immunohistochemical features of appendectomy specimens were included in the study. RESULTS: A total of 29 articles involving 38 patients with XGA, were retrospectively analyzed. Twenty (52.6%) of the 38 patients, aged 3 to 78 years (median: 34; IQR: 31) were female, and the remaining 18 (47.4%) were male. Twenty-five patients were diagnosed with acute appendicitis, ruptured appendicitis, or subacute appendicitis, and the remaining 13 patients underwent surgery for tumoral lesions of the ileocecal region. Twenty-two of the patients underwent urgent or semi-urgent surgery, and the remaining 16 patients underwent interval appendectomy. CONCLUSION: Xanthogranulomatous inflammation rarely affects the appendix vermiformis. It is associated with significant diagnostic and therapeutic dilemmas due to its variable presentation. It is often associated with interval appendectomies, and a significant number of patients require bowel resection due to the common presentation of a tumoral lesion. XGA is usually identified retrospectively on surgical pathology and has no unique features in preoperative diagnostic studies.

Is right lobe liver graft without main right hepatic vein suitable for living donor liver transplantation?

BACKGROUND: Since the first living donor liver transplantation (LDLT) was performed by Raia and colleagues in December 1988, LDLT has become the gold standard treatment in countries where cadaveric organ donation is not sufficient. Adequate hepatic venous outflow reconstruction in LDLT is essential to prevent graft congestion and its complications including graft loss. However, this can be complex and technically demanding especially in the presence of complex variations and congenital anomalies in the graft hepatic veins. CASE SUMMARY: Herein, we aimed to present two cases who underwent successful right lobe LDLT using a right lobe liver graft with rudimentary or congenital absence of the right hepatic vein and describe the utility of a common large opening drainage model in such complex cases. CONCLUSION: Thanks to this venous reconstruction model, none of the patients developed postoperative complications related to venous drainage. Our experience with venous drainage reconstruction models shows that congenital variations in the hepatic venous structure of living liver donors are not absolute contraindications for LDLT.

Differences in parents of pediatric liver transplantation and chronic liver disease patients.

BACKGROUND: With advancements in the treatment of chronic liver disease (CLD), including liver transplantation (LT), quality of life and satisfaction after LT have become an important issue for pediatric patients and their parents. More evidence-based information is needed to describe and assess the impact of pediatric CLD on parents and the satisfaction of parents with treatment to better understand their needs. AIM: To assess the satisfaction of parents of pediatric LT patients and that of parents of pediatric CLD patients. METHODS: During this survey, data were collected from parents of pediatric patients who underwent LT between January 2010 and April 2017 (LT group; n = 91) and parents of pediatric patients with chronic liver disease (CLD group; n = 94). Group comparisons were made based on the pediatric health-related quality of life (PedsQL) health care parent satisfaction scale, impact on family scale (IFS) and demographic characteristics. The PedsQL was administered to parents during a phone interview and the results were used to assess the health care-related satisfaction of parents. The IFS was used to assess the impact of the child's CLD status on the family. Demographic variables such as education level (elementary vs middle vs high vs university), monthly income (low vs middle vs high), and place of residence (village vs town vs city) were compared between CLD and LT parent groups. Finally, PedsQL and IFS results were also analyzed according to demographic variables. RESULTS: A total of 185 parents aged 19 to 65 years were included. There were statistically significant differences between the LT and CLD groups in terms of career (P < 0.001), monthly income (P = 0.016), and education level (P = 0.041). According to the PedsQL results, family inclusion, communication, technical skills, emotional needs, and overall satisfaction were significantly different between the groups; the LT group had consistently higher scores (P < 0.001). Additionally, scores for the IFS parameters of financial impact, familial-social impact, personal strain, and total impact were consistently higher for the LT group (P < 0.001). There were statistically significant relationships between education level, monthly income, and place of residence according to the IFS results but not the PedsQL results. There were inverse relationships between the difficulties that parents experience because of their child's health and education levels, monthly income, and place of residence. However, no relationship was found between education level, monthly income, or place of residence and satisfaction with health care services provided in the hospital according to the PedsQL results. CONCLUSION: Parents of children who underwent LT were very satisfied with the health care services provided to their children. However, they had more difficulties than parents of children with CLD.

Attitudes, awareness, and knowledge levels of the Turkish adult population toward organ donation: Study of a nationwide survey.

BACKGROUND: The most important factors affecting attitudes on organ donation are socioeconomic, educational, cultural, and religious factors in many countries. AIM: To evaluate the attitudes, awareness, and knowledge levels of the Turkish adult population toward organ donation. METHODS: This nationwide study surveyed 3000 adults (≥ 18 years) in Turkey. To ensure a representative sample, the Nomenclature of Territorial Units for Statistics-II (modified for Turkey) was used. Turkey was divided into 26 regions based on social, economic, and geographic criteria as identified by the Turkish Statistical Institute. A stratified sampling method was used with an even distribution of adults across cities and towns based on population data. Data were collected by the PRP Research and Consultancy Company using computer-assisted personal interviews. RESULTS: Out of 3000 individuals represented in the study population, 1465 (48.8%) were male and 1535 (51.2%) female. The results showed that most participants were under 45 years (59.0%) and married (72.1%), some had a bachelor's degree or higher (21.9%), and very few (1.5%) had any direct experience with organ transplantation - whether in the family, or a family member on a transplantation waiting list. Most of the study population (88.3%) had not considered donating an organ, however, most (87.9%) said that they would accept an organ from a donor if they needed one. Among the individuals surveyed, 67% were willing to donate an organ to a close relative, while 26.8% would donate an organ to an unrelated person. Only 47.2% said they had adequate information about brain death, and 85.2% refused to consent to donating organs of family members declared brain dead. Only 33.9% thought they had adequate information about organ donation. The main source of information was the television. The two main reasons for refusing organ donation were that it was too soon to think about organ donation and the importance of retaining the integrity of the dead person's body. CONCLUSION: This study showed that Turkey's adult population has inadequate knowledge about organ donation. The study advocates for public education programs to increase awareness among the general population about legislation related to organ donation.

Attitudes, knowledge levels and behaviors of Islamic religious officials about organ donation in Turkey: National survey study.

BACKGROUND: The most important factors affecting the decision of organ donation are socioeconomic, educational, cultural, and religious factors. AIM: To evaluate Islamic religious officials' attitudes and behaviors toward and level of knowledge on organ donation and transplantation. METHODS: This study surveyed 2350 Islamic religious officials in Turkey. To ensure a representative sample, we used and modified the Nomenclature of Territorial Units for Statistics. Based on the Nomenclature of Territorial Units for Statistics-II, Turkey was divided into 26 regions. The number of Islamic religious officials in each city and town in each of the 26 regions was proportionate to the population. A stratified sampling method based on demographic factors, such as age, marital status, and educational level, was used. Data were collected by PRP Research and Consultancy Company using computer-assisted personal interviewing. RESULTS: Of the 2350 religious officials surveyed, 59.9% were in the age group of 35-54 years; 84.7% had either a bachelor's or a master's degree; 99.7% never donated an organ; and 75.4% were not considering donating in the future. About 22% of the religious officials said religious belief was their reason for not donating; 45.3% did not indicate any reason. Although 41.5% of participants considered cadaveric organ donation as the best source of organ transplantation, 36.3% deemed living donor transplantation as the best option. Meanwhile, 52.9% of participants considered donating an organ from a brain dead relative in case they were asked for permission; 80.1% considered donating to a relative, if necessary; 81.6% considered undergoing organ transplantation, if necessary. About 83.7% of participants deemed organ donation as a proper human behavior; 60.5% believed that it is allowed by Islam; 55% said they preach for organ donation at their mosque; and 41.1% said their views of organ donation were influenced by their leaders in society. CONCLUSION: Religious officials are unsure whether or not organ donation is respectful of their religious belief, but they consider donating an organ if a relative need to undergo organ transplantation.

Unusual infectious agents detected in appendectomy specimens: A retrospective analysis of 42 cases.

OBJECTIVES: The aim of this study was to evaluate the clinical and histopathological features of 42 patients with unusual infectious agents detected in their appendectomy specimens. MATERIAL AND METHODS: Between January 1999 and November 2018, 2.754 patients underwent emergency or incidental appendectomy in our clinic, and their pathology reports were retrospectively reviewed. Unusual infectious agents or eosinophilic infiltration of the appendix were reported in the initial pathological examinations of 57 patients. The pathological slides of these patients were re-examined by histopathologists. The examinations revealed that 15 of these patients had no microscopic findings suggestive of parasitic infections. The remaining 42 patients with unusual appendiceal infectious agents were included into the study. RESULTS: A total of 42 patients (25 females and 17 males) aged 18 to 75 years were included into this study. While 32 of these patients (76%) underwent emergency appendectomy with a presumed diagnosis of acute appendicitis (AAp), the remaining 10 patients underwent incidental appendectomy for various reasons. Twenty-two patients (52.4%) had histopathological changes consistent with AAp while 20 patients had no evidence of AAp. Histopathological examination revealed infection with Enterobius vermicularis in 38 of the patients, Taenia species in 2, and Ascaris lumbricoides and Actinomyces species in 1 patient each. A total of 24 patients were treated for infections with mebendazole (n = 20), albendazole (n =1), niclosamide (n = 2), and amoxicillin (n = 1). CONCLUSION: Unusual infectious agents should be considered as factors potentially triggering AAp, especially in patients living in endemic areas. The appendiceal stump should be inspected for parasite residues.

Ectopic liver tissue (choristoma) on the gallbladder: A comprehensive literature review.

BACKGROUND: Liver tissue situated outside the liver with a hepatic connection is usually called an accessory liver, and that without a connection to the mother liver, is called ectopic liver tissue. AIM: To identify studies in the literature on ectopic liver tissue located on the gallbladder surface or mesentery. METHODS: We present two patients and review published articles on ectopic liver tissue located on the gallbladder surface accessed via PubMed, MEDLINE, Google Scholar, and Google databases. Keywords used included accessory liver lobe, aberrant liver tissue, ectopic liver tissue, ectopic liver nodule, heterotopic liver tissue, hepatic choristoma, heterotopic liver tissue on the gallbladder, and ectopic liver tissue on the gallbladder. The search included articles published before June 2020 with no language restriction. Letters to the editor, case reports, review articles, original articles, and meeting presentations were included in the search. Articles or abstracts containing adequate information on age, sex, history of liver disease, preliminary diagnosis, radiologic tools, lesion size, surgical indication, surgical procedure, and histopathological features of ectopic liver tissue were included in the study. RESULTS: A total of 72 articles involving 91 cases of ectopic liver tissue located on the gallbladder surface or mesentery were analyzed. Of these 91 patients, 62 were female and 25 were male (no gender available for 4 patients), and the age range was 5 d to 91 years. Forty-nine patients underwent surgery for chronic cholecystitis or cholelithiasis, and 14 patients underwent surgery for acute cholecystitis. The remaining 28 patients underwent laparotomy for other reasons. Cholecystectomy was laparoscopic in 69 patients and open in 11 patients. The remaining 19 patients underwent various other surgical procedures such as autopsy, liver transplantation, living donor hepatectomy, Whipple procedure, and liver segment V resection. Histopathologically, hepatocellular carcinoma was detected in the ectopic liver tissue of one patient. CONCLUSION: Ectopic liver tissue is a rare developmental anomaly which is usually detected incidentally. Although most studies suggest that ectopic liver located outside the gallbladder has a high risk of hepatocellular carcinoma, this is not reflected in statistical analysis.

Knowledge, attitudes, and practices of Palestinian people relating to organ donation in 2016: a cross-sectional study.

BACKGROUND: Organ transplantation is the treatment of choice for organ failure, but organs are scarce and their availability is affected by relational ties, religious beliefs, cultural influences, body integrity, medical mistrust, and other factors. This aim of this study was to assess the knowledge, attitudes, and practices of Palestinian population with respect to organ donation. METHODS: In this cross-sectional study, we used a validated questionnaire delivered by land telephone to collect data on the knowledge, attitudes, and practices relating to organ donation in the general population of the West Bank. Stratified sampling and simple random sampling were applied using data obtained from the Palestinian Telecommunication Group in 2016. Stata version 20 was used for statistical analysis, and a p value less than 0·05 was considered significant. Ethics approval was obtained from the Institutional Review Board of An-Najah National University, and all participants gave verbal informed consent. FINDINGS: The questionnaire was completed by 385 (68%) of 565 people approached (mean age 42 years [SD 14·13]). 266 (69%) respondents were married, 311 (80%) were employed, and 375 (97%) were Muslim. 136 (35%) respondents were university students or post-graduates. Half of participants lived in urban areas. Local religious clergy were reported as being the source of general information by 150 (40%) participants. 273 (71%) respondents had adequate knowledge about organ donation, TV being the main source of information for 207 (60%) participants. 70 (26%) respondents would consider donation only after death, and 342 (67%) respondents would only consider donating to a close family member, whereas 341 (100%) respondents believed that their organ could be misused and 219 (64%) believed organ donation carries a health risk. 135 (49%) respondents preferred to donate to a recipient of the same religion. 266 (78%) individuals believed that organ donation should be promoted in the occupied Palestinian territory, although 188 (55%) reported organ donation to be culturally unacceptable. Religious beliefs and fears of complications were the main obstacles to organ donation. An adequate level of knowledge was associated with the female sex (p=0·008), level of education (p=0·046), monthly income (p=0·041), and marital status (p=0·012), whereas a positive attitude to organ donation was associated with religious score (p=0·015), marital status (p=0·031), and knowledge score (p=0·003). A high level of knowledge was associated with employment and the perception of organ donation as permitted in religion, whereas a positive attitude was associated with single marital status, high level of knowledge, and residence in cities. INTERPRETATION: Despite adequate knowledge and positive attitudes towards organ donation, a comprehensive study is necessary to fully understand the local characteristics that influence organ donation by Palestinians and to better inform decision makers and future policies. FUNDING: None.
