Abstract
PURPOSE OF REVIEW The aim is to review recent literature for percutaneous treatment of liver hydatid cysts (cystic echinococcosis: CE) via different techniques such as PAIR (puncture, aspiration, injection, and reaspiration), standard catheterization, and modified catheterization technique (MoCaT). RECENT FINDINGS PAIR is an established technique and considered to be safe and effective for CE1 and CE3a as it is associated with lower morbidity, mortality, recurrence, and shorter hospital stay as compared with surgery. Standard catheterization is also dedicated for the treatment of CE1 and CE3a. PAIR should be preferred for treatment of liver CE1 and CE3a cysts, since PAIR is associated with lower major complication rates and shorter hospital stay. However, standard catheterization technique is indicated when cysto-biliary fistula develops or any technical difficulty arises during the PAIR. In these cases it is needed to switch PAIR to standard catheterization to complete the procedure. SUMMARY For CE1 and CE3a cysts, PAIR and standard catheterization are the choice for percutaneous treatments, while MoCaT is a treatment option for CE2 and CE3b cysts.

Comparison of ethanol and hypertonic saline as a single ıntracystic agent in the percutaneous treatment of liver hydatid cysts. Abdom Radiol (NY) 2023; 48:1148-1153. [PMID: 36627404 DOI: 10.1007/s00261-022-03795-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2022] [Revised: 12/24/2022] [Accepted: 12/27/2022] [Indexed: 01/11/2023]
Abstract
PURPOSE In this study, the effects of hypertonic saline and ethanol as a single intracystic agents in the percutaneous treatment of liver hydatid cysts were compared. METHODS The 50 patients were separated into two groups as those administered 30% hypertonic saline alone as the intracystic agent in percutaneous treatment (33 patients, 52 cysts), and those administered 96% ethanol alone (17 patients, 26 cysts). Both groups were compared in terms of percentage of cyst volume reduction, complications, and treatment success. RESULTS The follow-up period was median 17.0 months (11.0-20.0) in the ethanol group and 17.0 (14.0-22.0) in the hypertonic saline group (p = 0.269). Complications were observed in 5 (19.2%) cysts applied with ethanol as the intracystic agent and in 7 (13.5%) of the cysts where hypertonic saline was used (p = 0.521). Clinical success was evaluated as 100% in both groups. The percentage of cyst volume reduction according to the initial volume was determined as mean 75.6 ± 20.43 (28.19-98.13) in the ethanol group cysts and as 68.2 ± 16.45 (26.39-97.48) in the hypertonic saline group (p = 0.427). CONCLUSION The results of this study demonstrated similar efficacy of hypertonic saline and ethanol in the percutaneous treatment of CE1 and CE3A liver hydatid cysts. These results suggest that the use of hypertonic saline as a single intracystic agent in the percutaneous treatment of CE1 and CE3A liver hydatid cysts provides sufficient efficacy of treatment and cyst volume reduction. Nevertheless, there is a need for further prospective, randomized studies to support these findings.

Abstract
Percutaneous aspiration-injection-reaspiration (PAIR), also called sclerotherapy, is a minimally invasive, inexpensive and safe technique for the treatment of abdominal cysts in humans. A study was planned to evaluate the feasibility of this procedure in the management of abdominal cysts in sheep and goat. Adult ewes (n = 5) and one doe (n = 1) found to have abdominal cysts (one cyst/animal) on repeated survey ultrasonography (USG) were included in the study. The animals were restrained in standing position. A hypodermic needle (G-18) securely attached to a 10-mL Dispovan syringe was carefully passed under ultrasound guidance into the abdominal cyst in all these animals. Depending on the size of the cyst, 1.0-5.5 mL fluid was aspirated, and 0.5-2.0 mL of 20% hypertonic saline solution infused. The needle was thereafter kept in situ for 10 min. The maximum possible volume of the cyst content was reaspirated and the needle withdrawn. On day 7, sclerotherapy was repeated in five animals showing no appreciable reduction in cyst size by USG. USG was repeated on days 30 and 90. All the cysts except one responded to PAIR during this period. From this study it can be concluded that sclerotherapy using hypertonic saline (20%) is a minimally invasive, inexpensive, effective and safe interventional ultrasonographic technique for the treatment of abdominal cysts in sheep and goats. However, the procedure needs further evaluation after using different sclerotic agents of varying concentrations and duration of their retention in the cysts in a sufficient number of animals with cysts.

Abstract
OBJECTIVES This retrospective study aims at demonstrating the success rate, effectiveness, and advantages of alcohol as a scolicidal and sclerosing agent for the percutaneous treatment of liver hydatid cysts. METHODS A total of 554 liver hydatid cysts obtained from 347 patients admitted between January 2008 and February 2016 were retrospectively investigated. Of these, 435 (78.5%), 91 (16.4%), and 28 (5%) were classified as Gharbi type 1, 2, and 3, respectively. Type 1 and 2 cysts were treated using PAIR (puncture, aspiration, injection, respiration) and single puncture catheterization methods; type 3 lesions were treated using a modified catheterization technique. Alcohol was used as a scolicidal and sclerosing agent in all procedures. RESULTS After excluding three lesions (0.5%) because of lack of parenchymal support during catheterization, 274 (49.7%), 250 (45.3%), and 27 (4.9%) of 551 lesions were treated with PAIR, single puncture catheterization, and modified catheterization techniques, respectively. Therefore, a 99.5% of technical success rate was obtained. Major complications in 2 patients (0.5%) and minor complications were observed in 36 patients (10.3%). Mean hospital stay was 1.55±2.3 days (range: 0-23 days). Patients were followed-up for mean 19.6 months (range: 6-83 months), during which recurrences were detected in 19 patients (5.4%). CONCLUSIONS The use of alcohol as a scolicidal and sclerosing agent during the percutaneous treatment of liver hydatid cysts is associated with a high success rate and low rates of recurrence and complications, and should be considered an important alternative to surgical procedures.

Abstract
OBJECTIVE The purpose of this study was to determine the long-term results of a modified catheterization technique for percutaneous treatment of hepatic cystic echinococcosis (CE) types 2 and 3b and to retrospectively compare the results of puncture, aspiration, injection, and reaspiration (PAIR); standard catheterization; and the modified catheterization technique. MATERIALS AND METHODS Seventy-three patients (37 male, 36 female; 75 cysts) with CE types 2 and 3b who underwent percutaneous treatment from March 1991 to August 2008 were included. Informed consent from all patients and approval of the ethics board were obtained. Patients were 6-79 years old. Twenty-three cysts (30.6%) were treated with PAIR, 26 (34.7%) with standard catheterization, and 26 (34.7%) with the modified catheterization technique. The results of the three techniques were statistically compared. RESULTS Among all patients, the cysts decreased in volume by 61.1% (range, 5-100%). Cysts recurred in 11 (47.8%) patients treated with PAIR, three (11.5%) treated with standard catheterization, and one (3.8%) treated with the modified catheterization technique. The recurrence rate was not significantly different between standard catheterization and the modified catheterization technique (p > 0.05), whereas significantly more recurrences developed after PAIR than with the other two techniques (p < 0.05). Twelve (16.4%) major and 16 (21.9%) minor complications developed. Significantly fewer major complications occurred with PAIR than with the modified catheterization technique, but the difference between standard catheterization and the other two techniques was not significant. CONCLUSION Treatment of CE types 2 and 3b with the modified catheterization technique was associated with a recurrence rate lower than what is seen with other techniques, and therefore it appears to be a safe, reliable, and efficient alternative.

Abstract
The echinococcoses are chronic, parasitic diseases that are acquired after ingestion of infective taeniid tapeworm eggs from certain species of the genus Echinococcus. Cystic echinococcosis (CE) occurs worldwide, whereas, alveolar echinococcosis (AE) is restricted to the northern hemisphere, and neotropical echinococcosis (NE) has only been identified in Central and South America. Clinical manifestations and disease courses vary profoundly for the different species of Echinococcus. CE presents as small to large cysts, and has commonly been referred to as 'hydatid disease', or 'hydatidosis'. A structured stage-specific approach to CE management, based on the World Health Organization (WHO) ultrasound classification of liver cysts, is now recommended. Management options include percutaneous sterilization techniques, surgery, drug treatment, a 'watch-and-wait' approach or combinations thereof. In contrast, clinical manifestations associated with AE resemble those of a 'malignant', silently-progressing liver disease, with local tissue infiltration and metastases. Structured care is important for AE management and includes WHO staging, drug therapy and long-term follow-up for at least a decade. NE presents as polycystic or unicystic disease. Clinical characteristics resemble those of AE, and management needs to be structured accordingly. However, to date, only a few hundreds of cases have been reported in the literature. The echinococcoses are often expensive and complicated to treat, and prospective clinical studies are needed to better inform case management decisions.

Abstract
BACKGROUND To compare the effectiveness and safety for hydatid disease treatment, the 2 new minimally invasive therapies: laparoscopic and PAIR (puncture, aspiration, injection, and reaspiration) were compared by systematic meta-analysis. METHODS A comprehensive analysis of published cases from 1990 to 2014 was performed using PubMed database. A total of 231 publications on laparoscopic treatment of hydatid cysts and 298 publications on the PAIR treatment were identified. Thirty-eight studies involved 1230 laparoscope-treated subjects and 41 involved 2686 PAIR-treated subjects in this review. The effectiveness and safety of emphasis is placed on the recurrence, insufficient response, death, cure, and postoperative complications. Operation time and hospital stay are also discussed as new evaluation index. The stages of cyst are summarized to determine which stage is suitable for PAIR. RESULTS Clinical and parasitological cure occurred in 98.7% of patients undergoing laparoscopic intervention and in 97.5% of patients receiving PAIR plus chemotherapy (P<0.014). Recurrence occurred in 1.0% and 1.6%, respectively (P<0.087). Insufficient response occurred in 0.16% and 0.9%, respectively (P<0.009); 2 patients died in each group (P<0.594). Allergic reaction/urticarial/anaphylactic shock occurs in 0.14% and 4.24% of patients receiving laparoscopic intervention and PAIR plus chemotherapy, respectively (P<0.001). Infection/abscess (5.37% and 2.57%; P<0.001) and surgical-related complications (7.32% and 3.43%; P<0.001) were seen more frequently in laparoscopic intervention subjects than PAIR plus chemotherapy subjects. CONCLUSIONS Laparoscopic therapy and PAIR intervention are shown to be safe and effective alternative for open surgery with suitable indication such as cyst type and location. They have different postoperative complication features. The biliary fistula/bile leakage was more frequent in laparoscopic intervention (P<0.001) and fever occurred more in PAIR plus chemotherapy patients.

Abstract
BACKGROUND Hydatid disease of the liver is endemic in cattle rearing areas of the world. A variety of treatment options are available in its management. The common treatment options are medical therapy, surgery and puncture-aspiration-injection-reaspiration (PAIR) therapy. OBJECTIVES This study was performed to evaluate the effectiveness of PAIR therapy in the treatment of hepatic hydatid disease. PATIENTS AND METHODS This cross sectional study was carried out on 15 consecutive patients (Male: 2, Female: 13; Age group: 11-80 years) with hepatic hydatid disease and were treated by PAIR therapy and followed up for a period of 1 year. The cysts were punctured under local anesthesia with an 18G needle using sonographic guidance. Betadine (10% povidone iodine + 1% free iodine) was used as scolicidal agent and allowed to act for 30 min. Cysts larger than 5 cm (n = 5) were drained using an 8F pig tail catheter. The therapeutic response was studied by assessing the reduction in the cyst size, progressive solidification of the cyst, calcification of the wall and increase in the echogenicity of the cyst with pseudomass appearance on serial ultrasound examinations performed on the next day, after 1 month, at 3 months, 6 months and 1 year after the procedure. RESULTS Ten patients (66.7%) had Gharbi type I cysts, two (13.3%) had type II and three (20%) had type III cysts. All the patients (100%) showed reduction in cyst size over a 3-6 month period. Pseudomass appearance with solidification was seen in 73% of the patients and calcification was seen in 46.6%. None of the patients developed anaphylaxis, recurrence or peritoneal seedlings. Pain at the injection site was the most common complication observed. CONCLUSION PAIR therapy is an effective minimally invasive treatment for Gharbi type I-III hepatic hydatid cysts. It is a cost effective and safe procedure with significant reduction in the duration of hospital stay.

Abstract
Although splenic involvement alone in hydatid disease is very rare, spleen is the third most common organ involved in hydatid disease. The rarity of splenic hydatid disease poses a diagnostic challenge for clinicians, particularly in non-endemic areas. As the hydatid cyst can present as a simple cyst without having the classic serological and imaging features, and later can lead to life-threatening complications like anaphylaxis, hydatid disease of spleen should be considered in differential in every patient in endemic areas with cystic lesion of spleen until proved otherwise. The author used the keyword “splenic hydatid cyst” in PubMed and reviewed the scientific literatures published from January 1965 to June 2012. The present review is to accentuate the incidence, classification, clinical and pathophysiological features, differential diagnosis, diagnostic modalities, and treatment choices of hydatid cyst of spleen along with follow-up strategy and newer treatment approaches.

Abstract
AIM: To determine the efficacy and success of percutaneous aspiration irrigation and reaspiration (PAIR) in the management of hepatic hydatidosis.
METHODS: Twenty-six patients with 32 hepatic hydatid cysts had PAIR. Twenty-two patients received at least 2 wk of drug therapy before the procedure was carried out to reduce the risk of recurrence from spillage during the procedure. The procedure was performed under local anesthesia with a 19-gauge 20 cm long needle, the cyst was punctured, cystic content (approximately 30 mL) was aspirated by a 12-14 F pigtail catheter and aspirated fluids were sent for analysis. Once the cyst was almost empty, two-thirds of the net amount of material aspirated was replaced by hypertonic saline and left in the cavity for about 30 min, with the catheter left in place for reaspiration of most of the fluid. When the amount of fluid drained was less than 10 mL per 24 h, the drainage catheter was removed.
RESULTS: All 32 cysts showed evidence of immediate collapse after completion of the procedure, and before discharge from hospital, ultrasound examination showed fluid reaccumulation in all cysts. Serial follow-up showed a progressive decrease in the size and change in the appearance of cysts. To confirm the sterility of these cystic cavities, seven cysts were reaspirated on average 3 mo after the procedure. Investigations revealed no viable scolices.
CONCLUSION: PAIR using hypertonic saline is very effective and safe with proper precautions.

Abstract
BACKGROUND Hepatic hydatid cyst is an important public health problem in parts of the world where dogs are used for cattle breeding. Management of uncomplicated hepatic hydatid cysts is currently surgical. However, the puncture, aspiration, injection, and re-aspiration (PAIR) method with or without benzimidazole coverage has appeared as an alternative over the past decade. OBJECTIVES To assess the benefits and harms of PAIR with or without benzimidazole coverage for patients with uncomplicated hepatic hydatid cyst in comparison with sham/no intervention, surgery, or medical treatment. SEARCH STRATEGY The Cochrane Hepato-Biliary Group Controlled Trials Register, The Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library, MEDLINE, EMBASE, DARE, and ACP Journal Club and full text searches were combined (all searched October 2010). Reference lists of pertinent studies and other identified literature were scanned. Researchers in the field were contacted. SELECTION CRITERIA Only randomised clinical trials using the PAIR method with or without benzimidazole coverage as the experimental treatment of uncomplicated hepatic hydatid cyst (ie, hepatic hydatid cysts, which are not infected and do not have any communication with the biliary tree or other viscera) versus no intervention, sham puncture (ie, performing all steps for puncture, pretending PAIR being performed, but actually not performing the procedure), surgery, or chemotherapy were included. DATA COLLECTION AND ANALYSIS Data were independently extracted, and the risk of bias in each trial was assessed by the authors. Principal authors of the trials were contacted to retrieve missing data. MAIN RESULTS We found no randomised clinical trials comparing PAIR versus no or sham intervention. We identified only two randomised clinical trials, one comparing PAIR versus surgical treatment (n = 50 participants) and the other comparing PAIR (with or without albendazole) versus albendazole alone (n = 30 participants). Both trials were graded as 'adequate' for allocation concealment; however, generation of allocation sequence and blinding methods were 'unclear' in both. Compared to surgery, PAIR plus albendazole obtained similar cyst disappearance and mean cyst diameter with fewer adverse events (32% versus 84%, P < 0.001) and fewer days in hospital (mean + SD) ( 4.2 + 1.5 versus 12.7 + 6.5 days, P < 0.001). Compared to albendazole, PAIR with or without albendazole obtained significantly more (P < 0.01) cyst reduction and symptomatic relief. AUTHORS' CONCLUSIONS PAIR seems promising, but there is insufficient evidence to support or refute PAIR with or without benzimidazole coverage for treating patients with uncomplicated hepatic hydatid cyst. Further well-designed randomised clinical trials are necessary to address the topic.

Abstract
BACKGROUND This study aimed to evaluate the efficacy of percutaneous treatment of giant abdominal hydatid cysts. METHODS In this study, 15 abdominal giant hydatid cysts were treated with the catheterization technique, which included puncture of the cyst, aspiration of fluid, instillation and respiration of hypertonic saline solution, and catheterization and sclerosant therapy with absolute ethanol followed by free drainage of the cavity. The catheter was removed when the daily drainage was less than 10 ml. RESULTS The goals, including inactivation of the parasite and elimination of the mass effect, were achieved in all patients. Catheterization required a mean of 32 days (range, 14-52 days) and hospitalization a mean of 8.73 days (range, 2-30 days). No evidence for recurrence was observed in any patient during a mean follow-up period of 52.8 months (range, 36-72 months). CONCLUSION Percutaneous treatment of giant hydatid cysts is effective because it eliminates both the mass effect and the parasite and alleviates the symptoms. Although the long catheterization time associated with the procedure is unfavorable, it is tolerated by the patients.

Abstract
AIM To evaluate the long-term results of percutaneous imaging-guided treatment of hydatid liver cysts. MATERIALS AND METHODS Sixty patients with 77 hydatid liver cysts underwent percutaneous treatment with ultrasonography (US) or computed tomography (CT) guidance. Absolute alcohol and hypertonic saline were used for sclerosing the cysts after aspiration. Prophylactic albendazole treatment was given before and after the procedures. Follow-up US and CT were obtained periodically, and changes in cyst morphology were recorded. Minimum follow-up period for the patients included in this study was 12 months. Serological correlation was also available for a group of patients. The outcome of the procedures were categorized into five groups based on morphological changes observed by imaging. RESULTS Procedures were regarded as successful in 80% and unsuccessful in 20% of patients. Failures most often occurred with type III cysts; less than half (39%) of the total type III cysts had a successful outcome. On the other hand, all type I cysts ended up with cure. Anaphylaxis, pneumotorax and severe pain interrupting the procedures were also among the reasons of failure. CONCLUSION Percutaneous aspiration, injection and reaspiration (PAIR) of types I and II hydatid liver cysts is effective and safe in the long-term. Surgery should no longer be regarded as the first choice treatment in all hydatid liver cysts but should be reserved for type III and certain active type IV cysts.

Abstract
BACKGROUND/AIM Intrabiliary rupture of hepatic hydatid cyst causes serious morbidity and mortality. These patients are usually managed surgically. We evaluated the feasibility and outcome of an alternative method of treatment of these patients. METHODS Seven patients with ruptured hepatic hydatid into the biliary tract underwent endoscopic treatment consisting of endoscopic sphincterotomy, cyst material extraction and hypertonic saline lavage via nasocystic catheter. RESULTS Median age of patients was 40 years (range 17-50 years) with a male:female ratio of 2:5. Abdominal pain, jaundice and fever were seen in all patients. Six out of seven patients were positive for hydatid serology. All patients were successfully treated by endoscopic sphincterotomy, clearance of cyst material and hypertonic saline lavage. On a follow-up of 6 months to 4 years (median, 3.5 years), ultrasonography, computed tomography of the abdomen and magnetic resonance imaging of the abdomen showed a complete cure. There were no complications related to procedure. CONCLUSIONS This study demonstrates endoscopic treatment as one of the therapeutic options of ruptured hepatic hydatid cyst into the biliary tract.

Abstract
BACKGROUND Hepatic hydatid cyst is an important public health problem in parts of the world where dogs are used for cattle breeding. Management of uncomplicated hepatic hydatid cysts is currently surgical. However, the puncture, aspiration, injection, and re-aspiration (PAIR) method with or without benzimidazole coverage has appeared as an alternative to surgery over the past decade. OBJECTIVES To assess the benefits and harms of PAIR with or without benzimidazole coverage for patients with uncomplicated hepatic hydatid cyst in comparison with sham/no intervention, surgery, or medical treatment. SEARCH STRATEGY The Cochrane Hepato-Biliary Group Controlled Trials Register, The Cochrane Controlled Trials Register in The Cochrane Library, MEDLINE, EMBASE, DARE, and ACP Journal Club and full text searches were combined (all searched October 2004). Reference lists of pertinent studies and other identified literature were scanned. Researchers in the field were contacted. SELECTION CRITERIA Only randomised clinical trials using the PAIR method with or without benzimidazole coverage as the experimental treatment of uncomplicated hepatic hydatid cyst (ie, hepatic hydatid cysts which are not infected and do not have any communication with the biliary tree or other viscera) versus no intervention, sham puncture (ie, performing all steps for puncture, pretending that PAIR is being performed, but actually not performing the procedure proper), surgery, or chemotherapy were included. DATA COLLECTION AND ANALYSIS Data were independently extracted and methodological quality of each trial was assessed by the authors. Principal authors of the trials were contacted to retrieve missing data. MAIN RESULTS We found no randomised clinical trials comparing PAIR versus no or sham intervention. We identified only two randomised clinical trials, one comparing PAIR versus surgical treatment (n = 50) and the other comparing PAIR (with or without albendazole) versus albendazole alone (n = 30). Both trials were graded as 'adequate' for allocation concealment; however, generation of allocation sequence and blinding methods were 'unclear' in both of them. Compared to surgery, PAIR plus albendazole obtain similar cyst disappearance and mean cyst diameter with fewer adverse events (32% versus 84%, P < 0.001) and fewer days in hospital (mean + SD) ( 4.2 + 1.5 versus 12.7 + 6.5 days, P < 0.001). Compared to albendazole, PAIR with or without albendazole obtain significantly more often (P < 0.01) cyst reduction and symptomatic relief. AUTHORS' CONCLUSIONS PAIR seems promising, but there is insufficient evidence to support or refute PAIR with or without benzimidazole coverage for treating patients with uncomplicated hepatic hydatid cyst. Further well-designed randomised clinical trials are necessary to address the topic.

Abstract
OBJECTIVE The purpose of this study was to compare the effect of intracystic injection of albendazole and hypertonic saline in patients with liver hydatid disease. MATERIALS AND METHODS Fifty-nine patients with a total of 109 hydatid cysts were treated percutaneously. In all cases, local anesthesia was applied. Twenty percent hypertonic saline was used in 31 patients (40 cysts, group 1) as the scolicidal agent, and albendazole solution was used in 28 patients (69 cysts, group 2). The PAIR (percutaneous puncture, aspiration, injection, reaspiration) method was applied in group 1. In group 2, we used a different procedure that could be called the PAI (percutaneous aspiration and injection) method. After this procedure, routine sonography and CT examinations were conducted. The results of both groups were compared. RESULTS Follow-up examinations showed that liver hydatids expanded approximately to their original size after a significant reduction during the first month. In the follow-up period, fluid contents totally disappeared; thickening and irregularities were also observed in the cyst walls and a solid, hyperechogenic, heterogeneous pseudotumor appearance representing a degenerated membrane was seen in all patients. Hypertonic saline solution inactivated the scolices from the beginning of the treatment. However, scolices were inactive in the cysts aspirated 1 month after the procedure in group 2. A significant correlation was noted between elapsed time after the treatment and the cyst size using Wilcoxon's signed rank test (p = 0.000). No difference was seen between two groups in the amount of cyst size reduction using the Mann-Whitney test (p =0.521). CONCLUSION In addition to its oral use, albendazole may be injected intracystically as we did in our study. It sterilizes the cyst cavity and affects scolices as well.

Abstract
PURPOSE To evaluate the effectiveness and long-term results of percutaneous treatment for hydatid liver cysts in pediatric patients. MATERIALS AND METHODS Thirty-four pediatric patients (15 male, 19 female; ages 4-17 years; mean age, 9.4 years) with 51 hydatid liver cysts underwent ultrasound (US)-guided percutaneous treatment with albendazole prophylaxis. There were 15 type II lesions with membrane detachment and 36 type I lesions resembling simple hepatic cysts with pure anechogenic content or small echogenic reflections and a regular well-delineated wall. The method of US-guided puncture, aspiration, injection of hypertonic saline solution, and reaspiration was preferred for 21 lesions. For the remaining 30 larger cysts, the intervention was performed with the same percutaneous technique but followed by catheterization, drainage, control cystography, and sclerotherapy with ethanol. During follow-up, US examinations were performed at 1, 3, 6, and 12 months for the first year and yearly thereafter. RESULTS Percutaneous treatment of hepatic hydatid disease was successful in 33 patients (97.1%). During follow-up, US findings in the lesions changed significantly; at year 1, the inner content of the lesions became heterogeneous with a semisolid appearance, and the mean reduction in volume was 81.4%. At 2-year follow-up, most hydatid cysts had become solid in nature and the reduction in volume reached 65%-99% (mean, 85.1%). There were no recurrences or additional lesions after the follow-up of 1-6 years (mean, 3.1 years). Average hospital stay for the whole group in this study was 3.5 days. CONCLUSIONS The long-term results of percutaneous liver hydatid cyst treatment in children are in accordance with the results in adults. Percutaneous treatment of uncomplicated type I and type II liver hydatid cysts in pediatric patients is an efficient and safe treatment with short hospitalization.

Abstract
PURPOSE This paper presents a modification of the known method for percutaneous treatment of hydatid cyst, the PAIR technique. It aimed to achieve safe aspiration of large symptomatic cysts and cysts with a danger of impending rupture. METHODS We designed a coaxial catheter system to achieve concomitant evacuation of cyst contents while infusing scolicidal agent. Hypertonic saline is used to wash out cyst contents and to kill protoscolices. This was followed by injection of a sclerosant (ethyl alcohol 95%) into the residual cyst cavity to prevent formation of a cyst collection after the procedure. Seventeen cysts in 14 patients were successfully aspirated. Follow-up plain radiographs, ultrasonography and CT were performed weekly in the first 4 weeks and then at 3, 6 and 12 months for all patients. Seven patients (9 drained cysts) were followed up for 2 years and 1 patient for 3 years. RESULTS All cysts were successfully aspirated. The following morphologic changes were noticed: a gradual decrease in cyst size (17 cysts, 100%), thickening and irregularity of the cyst wall due to separation of endocyst from pericyst (7 cysts, 41%), development of a heterogeneous appearance of the cyst components (8 cysts, 47%) and development of pseudotumor (2 cysts, 12%). None of the treated cysts disappeared completely. No significant procedure-related complications were encountered. CONCLUSION This modified PAIR technique is a reliable method for percutaneous treatment of risky and symptomatic hydatid cysts.

Abstract
A number of surgical and non-surgical options exist to treat cystic echinococcosis of the liver. For decades, surgical excision via a conservative or radical approach was the recommended approach for hepatic hydatid cysts. The availability of chemotherapeutic agents with significant activity against Echinococcus granulosis has made it possible to undertake ultrasound- or computed tomography-guided transhepatic percutaneous drainage (termed puncture, aspiration, injection, and re-aspiration (PAIR)) of hydatid cysts. Pre- and post-intervention chemotherapy with albendazole or mebendazole offers the advantage of reducing the risk of disease recurrence and intraperitoneal seeding of infection that may develop via cyst rupture and spillage occurring spontaneously or during surgery or needle drainage. PAIR appears to have greater clinical efficacy (i.e. a higher incidence of cure), lower rates of major and minor complications, mortality, and disease recurrence, and fewer days of hospitalization compared to patients treated surgically. For patients who fail drug therapy alone, PAIR is a safe and effective procedure of choice for patients with hepatic echinococcosis, and perhaps other anatomic sites of infection such as lung, peritoneum, kidney, and other viscera. Surgery should be reserved for patients with hydatid cysts refractory to PAIR because of secondary bacterial infection or for those with difficult-to-manage cyst-biliary communication or obstruction.

Abstract
Using meta-analysis methodology, we compared the clinical outcomes for 769 patients with hepatic cystic echinococcosis treated with percutaneous aspiration-injection-reaspiration (PAIR) plus albendazole or mebendazole (group 1) with 952 era-matched historical control subjects undergoing surgical intervention (group 2). The rate of clinical and parasitologic cure (P<.0001) was greater in patients receiving PAIR plus chemotherapy. Disease recurrence (P<.0001), major complications (anaphylaxis, biliary fistula, cyst infection, liver/intra-abdominal abscess, and sepsis; P<.0001), minor complications (P<.0001), and death (P<.0824) occurred more frequently among surgical control subjects. Fever (P<.002) and minor allergic reactions subjects (P<.0001) were more common among PAIR-treated subjects. The mean durations of hospital stay were 2.4 days for group 1 and 15.0 days for group 2 (P<.001). Compared with surgery, PAIR plus chemotherapy is associated with greater clinical and parasitologic efficacy; lower rates of morbidity, mortality, and disease recurrence; and shorter hospital stays.

Abstract
Echinococcosis is a zoonotic infection caused by Echinococcus spp. and is one of the most important helminthic diseases worldwide. Two forms of echinococcosis occur in Turkey, i.e. Echinococcus granulosus and E. multilocularis. The life cycle of E. granulosus is predominantly in dogs and sheep, and most sheep farmers in Turkey keep a dog or two. Stray dogs are numerous and prevention or treatment of infection in these dogs is very difficult. Cystic echinococcosis (CE) occurs throughout Turkey whereas alveolar echinococcosis (AE) predominantly occurs in the eastern Anatolian region of the country. Both CE and AE are known to be endemic but few surveys have been performed. Most data on human CE and AE have been collected from hospital records. The first reference of echinococcosis, "Kyste hydatique multiloculaire", in Turkey dates as far back to 1872 by an Ottoman Physician, C.R. Katibian. The results of the first Turkish study on E. granulosus were published in 1928. According to Ministry of Health records, 21303 patients had operations to treat or confirm CE in the period 1987-1994 which corresponds to approximately 2663 patients per year. The estimated surgical case rate of CE is 0.87-6.6 per 100000 in Turkey. The prevalence of E. granulosus infection in dogs in Turkey is between 0.32 and 40% and varies widely with geographical location. The reported prevalence of CE in domestic animals in Turkey has ranged from 11.2 to 50.7% and has varied widely with geographical location. Although no detailed information has been published on AE in domestic and wild animals in Turkey, the main definitive and intermediate hosts of E. multilocularis are assumed to be rodents and red foxes, respectively. However, there has been only a single published report of E. multilocularis in a wild animal (fox) in the northwest in 1965 by Merdivenci. The first human case of AE in Turkey was reported by Mutlu in 1939, and total cumulative reported case number is 202 between 1980 and 1998.

Abstract
PURPOSE The purpose of this study was to evaluate the safety and efficacy of sonographically guided percutaneous drainage and irrigation of hepatic hydatid cysts. METHODS Sixty-one patients with 84 hepatic hydatid cysts were treated using the puncture, aspiration, injection, and reaspiration (PAIR) technique under sonographic guidance. Patients with cysts larger than 6 cm in diameter underwent PAIR followed by percutaneous drainage (PAIR-PD). The cysts were sterilized by the injection of 1 of 2 scolicidal agents, 20% hypertonic saline solution (38 patients) or 0.5% silver nitrate (23 patients). All patients underwent follow-up examinations for 1 month-6 years after aspiration. Clinical and radiologic examinations and laboratory analyses were performed every month for the first 6 months and then at 3-month intervals. RESULTS Serial sonographic examinations revealed a heterogeneous echo pattern in 78 cysts (93%); a progressive decrease in diameter in 76 cysts (90%); calcification of the cyst wall, cystic contents, or both in 10 cysts (12%); and complete disappearance of 1 cyst (1%) in a patient who had been monitored for over 6 years. Five patients developed urticaria, and 6 developed fever. One patient developed a biliary fistula after the first aspiration attempt. Two patients developed infection of the cyst cavity after PAIR-PD and were successfully treated with oral antibiotics. An anaphylactic reaction developed in 2 patients and was successfully treated with antiallergenic medication. No recurrence of hydatid disease after PAIR or PAIR-PD was observed in any patient over the follow-up period of 72 months (mean, 26 +/- 27 months). CONCLUSIONS Percutaneous drainage of hydatid cysts is a safe, effective, and reliable treatment. Antiallergenic medication is required before PAIR or PAIR-PD. Both sclerosing agents, hypertonic saline and silver nitrate solutions, gave excellent results.

Abstract
Hydatid disease of the liver remains an important and challenging problem in rural areas; although, surgery is considered the treatment of choice, percutaneous treatment of hydatid cysts is relatively new, and the data related to it are limited. The purpose of the study was to present the results of percutaneous treatment of liver hydatid cysts. Thirty-four patients (13 male and 21 female), ranging in age between 14 and 80 years, with 55 liver hydatid cysts underwent percutaneous treatment with albendazole prophylaxis. Cysts were treated with a one-stage procedure that consisted of puncture of the cysts under guidance with computed tomography, aspiration of fluid, injection of hypertonic saline solution as scolicidal agent and reaspiration. Follow-up examinations showed progressive reduction and solidification of the cysts. The mean reduction in volume was 72%. No mortality, abdominal dissemination, or tract seeding occurred. Minor complications were urticaria with pruritus in two patients. One patient had a subcapusular hematoma without problem. Hospitalization courses varied from ambulatory procedures to 15 days of in-patient, mean hospital stay was 1.82 days. The results of percutaneous liver hydatid cyst treatment, indicating that the procedure is efficient and safe and offers complete cure in selected patients with a short hospitalization and that this technique should be considered an alternative to surgery.

Abstract
PURPOSE We report our technique for and results of percutaneous treatment of heterogenous, predominantly solid echopattern hepatic hydatid cysts (HHC), i.e., complex type IV cysts according to Gharbi's sonographic classification of HHC. METHODS Eight patients with nine complex type IV HHC were treated by percutaneous aspiration followed by hypertonic saline ablation, using a 14 Fr van Sonnenberg sump drainage catheter under sonographic and fluoroscopic guidance. RESULTS Successful drainage of cysts contents was achieved in all eight patients. No major complications, such as anaphylaxis, abdominal dissemination, cyst recurrence, or death, occurred. Minor complications including pain (n = 4), mild fever (n = 5), right reactive pleural effusion (n = 4), and transient hypernatremia (n = 2) were observed and managed conservatively. Follow-up imaging studies for an average period of 15 months (range 1-48 months) showed either complete healing (n = 3) or significant reduction in the size of the cyst with solidification (n = 6). CONCLUSION Nine complex type IV HHC were effectively treated by suction of the membranes and hypertonic saline ablation using a 14 Fr sump drainage catheter, without major complications.

Abstract
OBJECTIVE In this experimental study, the effectiveness of intracystic injection of albendazole sulfoxide solution was investigated as a new approach to percutaneous treatment in liver hydatid disease. METHODS Ten naturally infected sheep were selected and divided into two groups: a treatment group (n = 7), and a control group (n = 3). Intracystic injection of albendazole sulfoxide was performed in the first group, whereas the control group received intracystic distillated water injection instead. No reaspiration was performed in any group. RESULTS During the follow-up period of 6 months, serial sonographic examination revealed a significant decrease in the cyst size, progressive solidification, and complete separation of the germinal and the laminated membranes of hydatid cysts from the pericysts in the treatment group. In the control group, diameters and volumes of cysts were increased. All procedures were done without any complications. During the follow-up-period, liver function tests were normal. After 6 months, all sheep were killed and were examined for macroscopic and microscopic changes. Pathological examination showed pericyst hyalinization, inflammatory cells in the cyst wall, degeneration of laminated and germinal membranes, and necrotic material in the cyst cavity. No viable protoscoleces or daughter cysts were observed. CONCLUSION Albendazole sulfoxide injection as a scolecidal agent in the percutaneous treatment of cystic echinococcosis seems to be effective in this animal model. Further studies are suggested to evaluate the effectiveness of this procedure in human subjects.

Abstract
Hydatic disease caused by Echinococcus granulosus is an endemic disease and an important public health problem in some countries of the world. The results of surgical treatment are associated with a high rate of mortality, morbidity, postoperative recurrence and a long period of hospital stay and the medical treatment results are still controversial. Although the percutaneous aspiration and treatment of liver hydatid cysts were considered to be contraindicated due to risks of anaphylactic shock and dissemination of clear-crystal fluid into the abdomen, several reports of successful percutaneous treatment of liver hydatid cysts have been published in the literature. Today, percutaneous treatment of liver hydatid cysts is the most effective and reliable treatment procedure in the selected cases. In this review, indications, contraindications, method and techniques, healing criteria, complications, results and importance of the percutaneous treatment of liver hydatid cysts are discussed.

Abstract
We report a rare case of a patient with a primary hydatid cyst in the head of the pancreas who presented with obstructive jaundice caused by extrinsic compression of the intrapancreatic portion of the bile duct. The patient was treated successfully by ultrasound-guided percutaneous drainage of the cyst using hypertonic (20%) saline as the scolicidal agent and albendazole chemoprophylaxis before and after the drainage. The cyst was not visible on ultrasonography at 6 months follow up. Clinical, sonographic and serological follow up to 35 months showed no evidence of cyst recurrence or dissemination. In endemic areas of hydatid disease, hydatid cyst should be a differential diagnosis in cystic lesions of the pancreas in patients presenting with obstructive jaundice.

Abstract
BACKGROUND Trauma as a cause of hydatid cyst rupture leads to various clinical sequelae. However, extensive data in the current literature regarding clinical presentation and management of such patients are lacking. METHODS This article is a retrospective review of 16 patients with traumatic rupture of hydatid cysts treated at a university hospital in an endemic area. RESULTS Falls (44%) were the most common cause of trauma. The ruptured cysts were located in the liver in 13 patients (81%), in the spleen in 2 patients, and in the lung in 1 patient. Computerized tomography had a sensitivity of 100% in demonstrating cyst rupture; whereas, ultrasonography had a sensitivity of 85%. Ten patients (62%) had rupture into the peritoneal cavity and 5 patients (31%) into the biliary tree. Five (31%) of the cysts were infected. Surgical procedures included introflexion (five patients), pericystectomy-choledochoduodenostomy (three patients), external drainage-choledochoduodenostomy (two patients), unroofing-external drainage (two patients), splenectomy (two patients), unroofing (one patient), and right hepatectomy (one patient). Mean length of hospitalization was 15.9 days (range, 5-61 days). One patient (6%) died, and eight patients (50%) developed complications. Nine patients (56%) were followed-up for an average of 30 months (range, 3-72 months), and there was no recurrence. CONCLUSION Computed tomography is currently the most sensitive diagnostic tool for demonstrating hydatid cyst rupture. The surgical options vary depending on intraoperative findings. Allergic reactions and recurrence as a result of intraperitoneal spillage are not as common as once believed. Biliary rupture is associated with an increased rate of wound infection.

Abstract
Rupture and the sequellae of rupture are more important than the mass effect of hydatid cysts, except in the brain where the mass effect by itself has severe consequences. The biology of hydatid disease, including the complex interaction between primary and secondary hosts, is reviewed. The hydatid cyst always starts as a fluid-filled, cyst-like structure (Type I) which may proceed to a Type II lesion if daughter cysts and/or matrix develop. In some instances the Type II lesion becomes hypermature and due to starvation dies to become a mummified, inert calcified Type III lesion. Type I and II lesions may undergo three types of rupture: contained, communicating and direct. Contained rupture is clinically silent, but communicating rupture may cause biliary obstruction and evacuation or infection of the cyst. Direct rupture has the greatest clinical consequences which include anaphylaxis, dissemination of hydatid disease (secondary hydatosis) within the host, and bacterial infection of the pericyst cavity. The clinical implications of the hydatid disease at different stages are discussed. A plea is made for the development of an international medical hydatid registry employing uniform nomenclature and consistent reporting in order to allow more rational comparisons of different types of management.

Abstract
The purpose of this paper is to evaluate the significance of two CT findings: evidence of an exophytic component of part of a hydatid cyst and dilated ducts in the vicinity of a cyst. The CT scans and clinical records of 63 patients were reviewed. There was evidence that cysts with an exophytic component are probably unstable and unsuitable for treatment by percutaneous drainage or prolonged medical treatment. Dilated pericystic ducts are a relative contraindication to nonsurgical treatment because of the danger of complicating biliary obstruction. Surgery should not be delayed unduly when either sign is encountered.

Abstract
BACKGROUND In recent years percutaneous drainage has been used successfully to treat the hepatic hydatid cysts of echinococcal disease. We performed a controlled trial to compare the safety and efficacy of percutaneous drainage with those of surgical cystectomy, the traditional treatment. METHODS In a prospective study, we randomly assigned 50 patients with hepatic hydatidosis to treatment with percutaneous drainage (25 patients) or cystectomy (25). Albendazole (10 mg per kilogram of body weight per day for eight weeks) was administered to the patients who underwent percutaneous drainage. Serial assessments included clinical and biochemical examinations, ultrasonography, and serologic tests of echinococcal-antibody titers. RESULTS The mean (+/-SD) hospital stay was 4.2+/-1.5 days in the drainage group and 12.7+/-6.5 days in the surgery group (P<0.001). Over a mean follow-up period of 17 months, the mean cyst diameter decreased from 8.0+/-3.0 to 1.4+/-3.5 cm (P<0.001) after percutaneous drainage and from 9.1+/-3.0 to 0.9+/-1.8 cm (P<0.001) after surgery. The final cyst diameter did not differ significantly between the two groups (P=0.20). The cysts disappeared in 22 patients (88 percent) in the drainage group and in 18 (72 percent) in the surgery group (P=0.29). After an initial rise, the echinococcal-antibody titers fell progressively and at the last follow-up were negative (<1:160) in 19 patients (76 percent) in the drainage group and 17 (68 percent) in the surgery group (P=0.74). There were procedure-related complications in 8 patients (32 percent) in the drainage group and 21 (84 percent) in the surgery group, 17 of whom had fever postoperatively (P<0.001). CONCLUSIONS Percutaneous drainage, combined with albendazole therapy, is an effective and safe alternative to surgery for the treatment of uncomplicated hydatid cysts of the liver and requires a shorter hospital stay.

Abstract
Liver cystic echinococcosis (CE) in non-endemic areas poses several problems in the differential diagnosis of various space occupying lesions detected by US examination. Fine needle aspiration biopsy (FNAB) using teflon covered needles with a US visible marker may be very useful for the definitive diagnosis. In the Clinic of Parasitic and Tropical Diseases in Poznan, FNAB were performed in 121 patients with liver space occupying lesions, with an addition of an anthelmintic cover of albendazole. The biopsy material was examined parasitologically, cytologically, bacteriologically and immunologically. E. granulosus infection has been confirmed in 25 patients (20.6%), in 16 cases by finding parasite protoscoleces or hooks and in nine cases by detection of an antigen specific for E. granulosus, antigen 5 (Ag5). Additionally nine cases of malignancy (7.4%), four of angioma (3.3%) and three bacterial abscesses (2.5%) were diagnosed. There were no complications related to FNAB puncture. The algorithm of the clinical management of space occupying lesions suspected for CE was proposed. FNAB is a very important technique in the differential diagnosis of cystic echinococcosis.

Abstract
The authors report their experience with ultrasound (US)-guided percutaneous treatment of hydatid abdominal cysts (mainly hepatic). From November 1987 to January 1996 in Italy and in Kenya 231 cysts in 163 patients were treated with a technique called PAIR (puncture, aspiration, injection, re-aspiration), using 95% ethanol as a scolecide agent according to a routine protocol. In Kakuma, Turkana (Kenya) 141 cysts in 85 patients were treated with a simplified protocol and a portable US machine. No anaphylactic shock or peritoneal dissemination was observed. One failure was observed due to the proximity of the parasitic cyst to the gallbladder, resulting in a fistula between the two cavities; this complication was resolved by surgery. A few minor complications were observed. In all the other cases detachment of the germinal membrane and subsequent reduction in size was observed, with a more or less complete solidification of the cyst and reduction of serology titers. Only one cyst recurred after 4 years and was treated again by PAIR. Long-term results indicate that in type I, II and III cysts, according to the Gharbi classification, PAIR is a first-choice method for treatment of liver hydatid cysts, especially in developing countries.

Abstract
Surgery is still the main modality in the treatment of hepatic hydatid disease. Laparoscopic methods, with their low morbidity, have gained prominence in many fields and, in some cases, have nearly replaced open surgery. In this report, a laparoscopic method for the treatment of hepatic hydatid disease is described and the results in the first six cases are presented. The method involves the use of an aspirator-grinder apparatus designed specifically for laparoscopic surgery. The postoperative courses of the patients were very comfortable and no complication related to the laparoscopic technique occurred. The method achieves evacuation of all viable cyst contents with the patient benefits of laparoscopic surgery. The apparatus practically eliminates the risk of spillage. The postoperative parameters and the early follow-up results (21-27 months) are very encouraging.

Abstract
Surgery is the main modality in the treatment of hepatic hydatid disease. In this report, a laparoscopic surgical method is described, and the results in the first 16 cases are presented. The method involves the use of an aspirator-grinder apparatus that achieves effective evacuation of viable cyst contents with the patient benefiting from the laparoscopic approach. Cavity infection occurred in two patients and was treated conservatively. In another patient, postoperative ultrasonography revealed a thick-walled cavity containing a dense fluid. Because the patient was symptomatic, pericystectomy was performed during the sixth postoperative month. Early postoperative parameters and the early follow-up results in other patients (2-17 months) are encouraging. The method is particularly suitable for uncomplicated, early-stage cysts located in laparoscopically accessible locations.

Abstract
BACKGROUND Recently, drug treatment and percutaneous drainage have been used successfully when treating hepatic hydatid cysts. Until now, there is no published study comparing the relative safety and efficacy of these two forms of treatment. METHODS In a prospective study, 33 hepatic hydatid cysts were randomly distributed to receive percutaneous drainage (10), albendazole (10 mg.kg-1.day-1 for 8 weeks) plus percutaneous drainage (12), and albendazole alone (11). Patients were serially assessed by clinical and biochemical examinations, ultrasonography, and hydatid serology. RESULTS On serial ultrasonography, cysts attained heterogeneous echopattern in 18, uniform echogenicity in 11, and disappearance in 3. All 22 cysts treated with percutaneous drainage and only 2 (18.2%) cysts treated with albendazole alone reduced in size and change in echopattern (P < 0.01). Maximum size reduction was observed in cysts treated with a combination of percutaneous drainage and albendazole (P < 0.05). Complications observed with drainage were cyst infection in 2 patients, fever in 3, cyst biliary rupture in 1, and urticaria in 2. These were managed successfully without any mortality. Three patients who received albendazole developed reversible elevation of liver cell enzymes. CONCLUSIONS It was concluded that percutaneous drainage with albendazole therapy is an effective form of management for hepatic hydatid cysts.
