Factors Affecting the Choice of Treatment in Hepatic Hydatid Cyst Surgery

The prevalence of hydatid cyst in raw meat products: a global systematic review, meta-analysis, and meta-regression

Hydatid cyst contamination in food presents a persistent and pervasive threat to public health. Hence, several studies have been published on hydatid cysts in raw meat products. The current study aimed to meta-analyze the prevalence of hydatid cysts in meat. The search was performed in international databases, including PubMed, Web of Science, Scopus, and Google Scholar, from January 1, 2000, to February 10, 2024. A meta-analysis of prevalence was conducted using the metaprop command in the subgroups of countries, animals, and WHO regions. Meta-regression of the prevalence of hydatid cysts in meat over time and sanitation services ranking was conducted using a random effects model (restricted maximum--likelihood). Fifty-seven published references with 130 data reports were included in the study. The lowest and highest prevalence of hydatid cysts in raw meat was observed in Sudan at 0.01%, 95%CI (0.01-0.02) and Italy at 69.86%, 95%CI (68.14-71.55), respectively. The highest prevalence of hydatid cysts was observed in Sheep (12.32%), Cattle (11.85%), and Buffalo (10.65%). The lowest and highest prevalence of hydatid cysts was South-East Asian Reg (2.77%) and European Region (33.21%), respectively. Meta-regression showed that the prevalence of hydatid cysts has significantly decreased over time (p-value = 0.021) and insignificantly decreased with sanitation services ranking (p-value = 0.679). Therefore, in order to maintain the existing conditions and even reduce the burden of hydatidosis, public health education, promotion of hygienic practices, and investment need to be carried out continuously.

The recurrence rate after primary resection cystic echinococcosis: A meta-analysis and systematic literature review

Cystic echinococcosis (CE) is a chronic, complex, zoonotic disease caused by Echinococcus Granulose tapeworms. The disease may present with a variety of symptoms, ranging from asymptomatic to fatal. Surgical intervention is the primary treatment modality for CE. Despite advances in surgical techniques and chemotherapy, disease recurrence remains a major concern. Therefore, we aimed to determine the true rate of CE recurrence after primary resection and identify possible factors that increase the risk of recurrence. A systematic search of Medline, PubMed, Embase, and Cochran Library was conducted to identify studies reporting the incidence of CE recurrence after primary radical surgery. Data were pooled using random effect models. The disease prevalence was determined by calculating the ratio of CE recurrence and the total number of patients. A meta-regression was conducted to identify any potential factors linked to recurrence. A total of 38 eligible studies, with a total of 6,222 CE patients who underwent primary surgical removal, revealed a pooled recurrence rate of 8% (95% CI: 6%-10%). However, significant heterogeneity was observed (I2 p-value <0.001). Subgroup analysis by region showed the highest incidence of recurrence in European and Turkish studies, with rates of 11% (95% CI: 7%-17%) and 9% (95% CI: 5%-14%), respectively. The lowest recurrence rate was observed in Asian studies, with a rate of 4% (95% CI: 2%-7%). Moreover, the non-radical intervention has a recurrence of 5% (95%CI: 4%-7%), radical 7% (95%CI: 6%-9%), and studies that contained both interventions have 10% (95%CI: 6%-16%), P-value= 0.04. This is the first meta-analysis to evaluate the overall incidence of CE recurrence after primary surgical removal. The study also revealed a substantial degree of heterogeneity across the included studies and indicated possible risk factors for higher recurrence rates, such as the study's geographic area, type of surgery and the year it was published. These findings will help to guide future research in developing effective strategies to prevent or reduce CE recurrence and improve patient outcomes.

Laparoscopic Management of Abdominal Echinococcosis: A Technical Report on Surgical Techniques and Outcomes

This technical report explores the efficacy and methodology of laparoscopic surgery for treating abdominal echinococcosis, a parasitic infection caused by Echinococcus granulosus. We highlight the zoonotic nature of the disease, which predominantly affects the liver and occasionally other organs, noting the challenge of its asymptomatic progression that complicates timely diagnosis and intervention. We detail our surgical technique using a standard laparoscopy kit to address abdominal hydatid cysts, emphasizing the critical importance of preventing cyst rupture and spillage to avoid recurrence and anaphylactic shock. We discuss considerations for opting for laparoscopy over open surgery, such as reduced postoperative morbidity, faster patient recovery, and lower costs, while also acknowledging limitations like restricted instrument movement and the absence of haptic feedback. We advocate hypertonic saline as the preferred scolicidal agent and strategies to minimize spillage and manage the residual cavity. In conclusion, we assert that laparoscopy offers a viable and effective treatment option for abdominal echinococcosis, emphasizing that optimizing outcomes for this benign condition hinges on careful patient selection and a conservative surgical approach.

Laparoscopic Management of Multiple Liver, Omental, Mesenteric, Peritoneal, and Round Ligament Hydatid Cysts-A Rare Report of a Case and a Systematic Literature Review

Hydatid cyst disease is a parasitic ailment with an endemic nature, predominantly affecting geographical areas with a tradition in animal husbandry. The most common localization of hydatid disease is in the liver (60%), followed by the lungs, with other organ localizations comprising less than 10%. The surgical approach to this condition can be carried out through open surgery or laparoscopy. The coexistence of hepatic and intraperitoneal hydatidosis often leads to the preference for open surgery. We performed a literature review aiming to retrieve data regarding demographic characteristics, clinical features, preoperative management, and surgical approach concerning these unusual localizations of hydatid disease. It was observed that the mesenteric localization frequently presented with acute abdominal pain (p = 0.038) and that the open approach was preferred in 85.71% of cases. Furthermore, an interdependence was identified between the localization of the cysts and the type of surgical approach (p = 0.001), with mesenteric localizations being approached through laparotomy and excision (p = 0.037), while omental localizations, due to the easier approach, benefited from laparoscopy with excision in 14.29% of cases. Overall, the laparoscopic approach was less frequently used, but its utilization resulted in a lower number of complications and faster recovery. Additionally, we present a rare case of hepatic and intra-abdominal hydatidosis, resolved exclusively through a laparoscopic approach, including a review of the literature for these uncommon localizations of hydatid disease. A 45-year-old patient diagnosed with multiple hydatid cysts, both hepatic and intraperitoneal, underwent surgical intervention with exploratory laparoscopy. Laparoscopic excision of peritoneal, epiploic, mesenteric cysts, and round ligament, along with laparoscopic inactivation, evacuation, and pericystectomy of hepatic hydatid cysts, was performed. The patient's recovery was uneventful, and she was reevaluated at 3 and 9 months without signs of recurrence. The association of hepatic hydatid cysts with multiple intra-abdominal localizations is not commonly encountered. The treatment of choice is surgical and is predominantly conducted through open surgery. The presented case is unique due to the exclusive laparoscopic approach in the management of mixed hepatic and intra-abdominal hydatidosis.
