Hydatid Disease of the Spleen: Single-Center Experience and a Brief Literature Review

Abstract

We found no significant difference in recurrence rates between splenectomy and spleen-sparing surgery, either in our patient cohort or among cases reported in the literature. Nevertheless, we cannot make any solid recommendations for either procedure based on these results, as the studies were largely retrospective.

Hydatid cyst of the pancreas: Report of an undiagnosed case of pancreatic hydatid cyst and brief literature review

“…Larvae with a diameter less than 0.3 mm can escape the liver's filtering system (first Lemman's filter) and reach the lungs where they are entrapped by a second capillary filtering system (second Lemman's filter). Larvae that escape the lung may then pass to any part of the human body via arterial circulation [1][2][3] . The organization of the filtering systems explain why hydatid cysts most commonly re- Diop et al [31] CT + MR + EUS Distal pancreatectomy + polar nephrectomy + partial cystectomy-Liver This patient arrived at the hospital with signs of acute pancreatitis.…”

“…Four different Echinococcus species have been defined as causative agents of hydatid disease in humans [1,2] . The most common species encountered in humans are the Echinococcus granulosus (E. granulosus), which causes cystic echinococcosis, and the Echinococcus multilocularis, which causes alveolar echinococcosis [1,2] . E. granulosus is responsible for 95% of the human hydatid cases reported.…”

“…In the biological life cycle of hydatid disease, carnivores are the definitive hosts while herbivores are the intermediary hosts. Humans themselves have no role in the biological life cycle and are usually infected after inadvertent ingestion of Echinococcus eggs in canine feces [1,2] . The disease continues to be a major public health issue in many regions of the world where agriculture and stockbreeding are primary sources of income.…”

“…Percutaneous drainage can be accomplished by puncture, aspiration, injection of hypertonic saline solution, and re-aspiration of cyst content (PAIR) or direct catheterization of the cyst [13,18,28] . These procedures should be specifically carried out in Type Ⅰ and Ⅱ PHCs, cysts with a diameter less than 50 mm, patients who refuse surgery, and cases with a higher anesthesia risk [1] . The main advantage of PAIR is the ability to show scoleces in the aspirated cyst fluid cytopathologically within a short period of time.…”

“…The risk associated with release of cyst contents into abdominal cavity is markedly lower with a PAIR procedure that is carried out by passing through parenchyma of solid organs like liver and spleen than it would be with pancreatic and other intraabdominal cysts [26] . In cases where minimally invasive surgical therapy has been contemplated, antihelminthic therapy should be administered before (≥ 4 d) and after (≥ 3-4 wk) the procedure in order to reduce intracystic pressure and prevent anaphylaxis [1] .…”
