Fasciolopsis buski, also called the giant intestinal fluke, is the largest intestinal fluke of the zoonotic trematode parasites and found mainly in Southeast Asian countries, including China. Fasciolopsis buski infection was formerly a common health problem in many countries, but it is now rare. Typically, it can be cured by oral drugs, but some infected patients need surgical intervention because of the severity of their condition or because of an unclear diagnosis or even misdiagnosis. Here, we report a case of a 15-year-old girl from Guizhou Province, China, presenting with recurrent upper-middle abdominal pain that was misdiagnosed as a choledochal cyst. Through laparotomy combined with postoperative histopathological examination, the source of the pain was proven to be mechanical biliary obstruction caused by F. buski infection. In the past, mechanical obstruction, especially biliary obstruction, caused by F. buski infection leading to surgery was not uncommon, but it is very rare in modern society. Moreover, delayed treatment and misdiagnosis of parasitic infection can lead to severe consequences. Therefore, we reviewed the previous literature on F. buski infection treated by surgical operation and summarized the characteristics and therapeutic strategies of these cases to raise clinicians\' awareness of this rare infection.

Fasciolopsiasis is rarely known as the parasitic disease in Nepal. Herein, we report a case of fasciolopsiasis in a 22-year-old man who was admitted in the hospital with abdominal pain, distension and loss of appetite for a month. He had previously diagnosed with acute viral hepatitis but, his abdominal pain was not resolving despite improvement in his liver function and general condition. During endoscopy an adult digenean worm was seen in the first part of the duodenum. After isolation, the worm was identified morphologically as Fasciolopsis buski. Microscogic examination of the patient\'s stool revealed eggs with a morphology consistent with F. buski. Eggs were yellow-brown, ellipsoidal, unembmbryonated, operculated, filled with yolk cells, with thin shell and ranging 118-130 µm in length and 60-69 µm in width. The abdominal pain of the patient was resolved after treatment with praziquantel. By the present study, it was confirmed for the first time that fasciolopsiasis is indigenously transmitted in Nepal. Accordingly, the epidemiological studies in humans and reservoir host animals should be performed intensively in near future.

During the monitoring of red deer (N = 124) and fallow deer (N = 13) populations in four neighbouring areas, the presence of Fascioloides magna was confirmed in southwestern Hungary. The prevalence and the mean intensity of the infection within the host populations ranged between 0 and 100% and 0-36.3, respectively. The determined prevalences are similar to that observed earlier in other European natural foci. The authors hypothesise that the appearance of F. magna in this region should have been a partly natural- and partly human-influenced process.

Infestation by the zoonotic trematode Fasciolopsis buski (fasciolopsiasis) is seen in several parts of South-East Asia. Abdominal pain, diarrhoea, mucosal ulceration, intestinal obstruction, anasarca, and even fatality are described following heavy infestation. We present here the case of a 10-year-old boy from the Barabanki district of Uttar Pradesh, India with heavy infestation by Fasciolopsis buski causing intestinal perforation. Fasciolopsiasis is by no means rare but its presentation as a case of intestinal perforation is extraordinary.

Fasciolopsiasis is a disease caused by the largest intestinal fluke, Fasciolopsis buski. The disease is endemic in the Far East and Southeast Asia. Human acquires the infection after eating raw freshwater plants contaminated with the infective metacercariae. There has been no report of fasciolopsiasis either in man or in animal in Malaysia. We are reporting the first case of fasciolopsiasis in Malaysia in a 39-year-old female farmer, a native of Sabah (East Malaysia). This patient complained of cough and fever for a duration of two weeks, associated with loss of appetite and loss of weight. She had no history of traveling overseas. Physical examination showed pallor, multiple cervical and inguinal lymph nodes and hepatosplenomegaly. Laboratory investigations showed that she had iron deficiency anemia. There was leukocytosis and a raised ESR. Lymph node biopsy revealed a caseating granuloma. Stool examination was positive for the eggs of Fasciolopsis buski. The eggs measure 140 x 72.5 microm and are operculated. In this case, the patient did not present with symptoms suggestive of any intestinal parasitic infections. Detection of Fasciolopsis buski eggs in the stool was an incidental finding. She was diagnosed as a case of disseminated tuberculosis with fasciolopsiasis and was treated with antituberculosis drugs and praziquantel, respectively.

A Vietnamese child presented with a history of abdominal pain. Shortly afterwards, he vomited eight live trematode flukes that were collected and morphologically identified as Fasciolopsis buski. The identification was confirmed by DNA analysis. Adult worms of F. buski from humans are very rarely seen except at autopsy, and this is the first such report from Vietnam.

Fasciolopsiasis, or infection by the intestinal fluke, Fascilopsis buski, is endemic in the eastern states of our country. While it is by no means a rarity, especially in the rural set up, awareness regarding this common parasitic infestation is still a much-needed entity. The importance of a strong degree of suspicion and early diagnosis cannot be over emphasised, if a successful campaign is to be launched in its control. With this as our central theme, we proceed to report a case of and unsually heavy Fasciolopsis buski infection in our hospital, which had failed to be diagnosed in a semi urban setup in UP.

A girl, aged 20 years presented with diarrhoea, vomiting, pain abdomen and loss of weight, the routine Stool examination revealed Fasciolopsis buski (giant intestinal fluke) in large numbers. Despite treatment with Praziquantel, she died after three days.
