Anisakiasis of the gastrointestinal tract is caused by the consumption of raw or undercooked seafood infected with larvae. Penetration of larvae into the gastrointestinal mucosa leads to severe epigastric pain, nausea, and vomiting, usually within hours of ingestion of the parasite. Suspicion for gastrointestinal Anisakiasis should be raised in patients with a compatible dietary history. Definitive diagnosis can be made by direct visualization of larvae via endoscopic examination. Although symptoms are self-limiting, the removal of larvae by gastroscopy can hasten relief of symptoms. There are a large number of cases of gastric anisakiasis reported from Japan, Korea, and Western Europe, where it is customary to consume raw fish. Cases reported from the United States are less common, and given the nonspecific symptoms of anisakiasis, the diagnosis can be missed. We report a patient who presented with gastroesophageal reflux disease like symptoms that started after ingesting raw fish. He was found by esophagogastroduodenoscopy to have white, filiform worms penetrating into the wall of his stomach, consistent with a diagnosis of gastric anisakiasis.

Review
BACKGROUND
Helminths sometimes require surgical or endoscopic intervention. Helminths may cause acute abdomen, mechanical intestinal obstruction, gastrointestinal hemorrhage, perforation, hepatitis, pancreatitis, and appendicitis. This study aimed to determine the surgical diseases that helminths cause and to gather, analyze the case reports, case series and original articles about this topic in literature.
METHODS
This study was designed as a retrospective observational study. In order to determine the studies published in literature, the search limits in Pub-Med database were set to 1 Jan 1957 and 31 Mar 2016 (59 yr), and the articles regarding Helminth-Surgery-Endoscopy were taken into examination. Among 521 articles scanned, 337 specific ones were involved in this study.
RESULTS
The most common surgical pathology was found to be in Ascaris lumbricoides group. was found to be the parasite that caused highest amount of acute appendicitis. Anisakiasis was observed to seem mainly because of abdominal pain and mechanical intestinal obstruction. causes duodenal pathologies such as duodenal obstruction and duodenitis. comes into prominence with appendicitis and gastrointestinal perforations. exhibits biliary tract involvement and causes common bile duct obstruction. Hookworms were observed to arise along with gastrointestinal hemorrhage and anemia. draws attention with gastrointestinal hemorrhage, mechanical intestinal obstruction.
CONCLUSION
Helminths may lead to life-threatening clinic conditions such as acute abdomen, gastrointestinal perforation, intestinal obstruction, and hemorrhages. There is a relationship between surgery and helminths. It is very important for surgeons to consider and remember helminths in differential diagnoses during their daily routines.

Review
Anisakiasis is a zoonotic parasitic disease caused by consumption of raw or undercooked fish or seafood infected with nematodes of the Anisakis, Pseudoterranova or Contracaecum genera. Here, we describe the first case of anisakiasis in Colombia and summarize the available literature. A 52-year-old female with a history of abrupt-onset sharp epigastric pain, nausea, vomit, diarrhea, and urticaria following fish consumption consulted the health service. The physical examination revealed moderate tenderness of the epigastric region; the laboratory evaluation showed leukocytosis and a simple X-ray and ECG showed no abnormalities. The diagnosis was made by endoscopic examination, which revealed a thickened gastric wall and a moving larval worm. An Anisakis larva was found and extracted endoscopically, which relieved the pain of the patient. Clinically, anisakiasis may present as a gastric, intestinal, extragastrointestinal or allergic disease. Diagnosis and treatment of anisakiasis are made by a dietary history, direct visualization and endoscopic extraction of possible larvae, which is the only effective therapy.

Review
Anisakiasis is an arising zoonosis induced by parasitic nematodes belonging to the family Anisakidae. Anisakiasis is often caused by the ingestion of larval nematodes in uncooked or minimally processed seafood dishes, which are regularly consumed by humans. Significant potential sources of infection are raw fish (e.g., sushi and sashimi) that can be found in traditional Japanese cuisine and can be part of the culinary tradition of consumption of raw or marinated fish that is particularly diffused in European countries. During the last five decades, the global prevalence of human anisakiasis has been rising, becoming an emergent major public health problem. Thus, there is an unmet need for well-defined and cost-effective methods aimed at killing Anisakis larvae, thus reducing the incidence of anisakiasis. In this mini-review, we discuss the clinical features of anisakiasis as well as the effectiveness and mechanisms of action of the main methods employed for increasing seafood safety and killing Anisakis larvae, including freezing, heating, use of high hydrostatic pressure, salting process, pepsin digestion method and use of garlic oil.

Anisakiasis is a gastrointestinal disease caused by infection with anisakid nematodes. larvae have been listed as distinct food poisoning agents in the manual of Food Poisoning Statistics, Japan since 2013. The reported numbers of food poisoning cases caused by larvae are gradually increasing. A total of 94.0% of the causative larvae species were identified as sensu stricto (), and 4.4% were identified as , among human-isolated anisakid nematodes examined in Tokyo Metropolitan Institute of Public Health, Japan from 2011 to 2018. species infecting fishes in Japanese waters differ depending on their habitat and depth. mainly infects fishes in the Pacific side of Japan, and mainly infects fishes in the East China Sea and Sea of Japan sides. Regarding the causative foods of anisakiasis, cases by ingestion of mackerel ( spp.) have been the most common in Japan, and cases caused by eating "marinated mackerel" accounted for 32.8% of the total in Tokyo from 2011 to 2017. However, the number of reports of food poisoning caused by skipjack tuna () was highest in May 2018 in Japan. A parasitological surveys of third-stage larvae in skipjack tuna in Japanese waters were conducted in 2018 and 2019, and it was confirmed that more infections of skipjack tuna may have occurred in 2018 than usual due to the meandering flow of the Black Current. Moreover, a portion of larvae migrated from visceral organs to the ventral muscle in live skipjack tuna before capture, suggesting that an extensive cold chain after capture cannot prevent anisakiasis. In fish species that were reported to be high frequency of causative food of anisakiasis, it is necessary to freeze or at least remove the ventral muscle.

Observational Study
INTRODUCTION
Anisakiasis is a zoonosis of parasitic origin whose diffusion seems to be continuously increasing.
OBJECTIVE
The aim of this study was to evaluate the benefits of a fish-free diet in patients allergic to Anisakis simplex as well as underlining the importance of awareness and prevention. Furthermore, we aimed to investigate the critical issues related to the spread of anisakiasis in relation to eating habits.
METHODS
Patients were assessed by means of skin prick tests (SPTs) and targeted laboratory testing, with an 18-month-long fish-free diet being recommended in cases of severe sensitization. The degree of awareness about anisakiasis was evaluated from interviews. Patients were subjected to follow-up visits after 18 months.
RESULTS
A total of 70 cases of sensitization to A. simplex were evaluated. The Interview answers highlighted a general state of misinformation among patients and healthy subjects along with a remarkable underestimation of anisakiasis-related risks. An overall lack of care regarding eating habits and diet plans also emerged. In 21 patients affected by severe sensitization, clinical and laboratory evaluations were repeated after 18 months of the subjects being on a fish-free diet. There was a remarkable improvement in serum IgE levels and clinical symptoms.
CONCLUSION
Data analysis proved the need to implement new and more effective awareness-raising and prevention campaigns in order to reduce the incidence of anisakiasis. It is crucial to establish an adequate diet therapy for sensitized patients. Evaluation of cytokine patterns suggests how a polyphenol-rich regime can activate regulatory T cell function and possibly reduce the allergic and inflammatory components of the disease.

We present a unique image from a case of anisakiasis that was detected incidentally in an elderly man during surveillance esophagogastroduodenoscopy. Given the popularity of sushi and sashimi throughout the world, we believe that our observations will raise awareness about the risk of Anisakis contamination in seafood.

Review
This review provides an inventory of the biodiversity of the anisakid species identified so far from fish and marine mammals of the NE Atlantic Ocean. The paper reviews and discusses various taxonomical and epidemiological aspects related to biodiversity assessment, with emphasis on: (1) taxa recognized as 'biological species' based on molecular/genetic markers; (2) current molecular/genetic approaches to identify the species at different developmental stages; (3) ecological data related to the actual geographical distribution and definitive host preferences of the species; (4) their distribution in various, commercially important fish species in northern European waters; (5) their possible occurrence in farmed fish; and, finally, (6) an update of their zoonotic potential as causative agents of anisakidosis in humans.
