Short-term outcome of adrenal radiofrequency ablation of adrenal cysts: a single-center experience. Sci Rep 2023; 13:3267. [PMID: 36841893 PMCID: PMC9968339 DOI: 10.1038/s41598-023-30330-7] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2022] [Accepted: 02/21/2023] [Indexed: 02/27/2023] Open
Abstract
Percutaneous thermal ablation is a minimally invasive treatment for liver, kidney, lung, bone, and thyroid tumors. This treatment also has been used to treat adrenal tumors in patients, but there is no evidence for the efficacy of thermal ablation of adrenal cysts. The present study was performed to analyze the experience of a single center with percutaneous radiofrequency ablation (RFA) of adrenal cysts and to evaluate its efficacy. The present study enrolled all patients who underwent percutaneous RFA for unilateral adrenal cysts from 2019 to 2021. All patients underwent USG-guided percutaneous aspiration of cystic fluid, followed by RFA. A total nine patients with adrenal cysts were included in this study. All of them underwent technically successful percutaneous RFA, with no immediate complication. Follow-up CT 3 months after RFA showed that six of the nine adrenal cysts showed good responses, with reductions in cyst volume ranging from 86.4 to 97.9%. One patient had poor response in the cyst size (volume reduction rate 11.2%). She underwent secondary RFA with resulting that the cyst volume reduced by 91.1%. After a median follow-up period of 17.2 months, eight patients showed no evidence of regrowth. The patient, who showed evidence of regrowth, declined any other treatment and has been under regular surveillance. None of the nine patients developed adrenal insufficiency during the follow-up period. In conclusion, percutaneous RFA is a safe and effective minimally invasive treatment for adrenal cysts, suggesting that percutaneous RFA may be a good alternative option in selected patients.

[PMID: 35913507 DOI: 10.1007/s00261-022-03621-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/06/2022] [Revised: 07/10/2022] [Accepted: 07/11/2022] [Indexed: 01/18/2023]
Abstract
OBJECTIVES To investigate predictive factors of treatment response following ethanol sclerotherapy of large renal cysts via computed tomography (CT). METHODS Retrospective study reviewed 71 patients (61.0 ± 13.2 years; M:F = 32:39) who underwent pretreatment CT and were treated with sclerotherapy of a large (> 5 cm) renal cyst (mean volume: 279.8 cc) using 99% ethanol from January 2010 to February 2019. Patients were followed up at least two times, short-term (defined as < 6 months, median 2.1 months) and long-term (defined as > 1 year, median 15.5 months), via ultrasound or CT. Suboptimal response was defined as the volume of residual cyst > 20 mL in each follow-up. Predictive variables of radiologic findings and radiomics features were analyzed using logistic regression analysis. RESULTS Suboptimal response rates were 33.8% and 18.3% at short-term and long-term follow-ups, respectively. In radiologic findings, patients with suboptimal response in the short-term follow-up showed a more frequent estimated cyst volume ≥ 270 mL (OR 14.8, 95% CI 3.9-55.9, p < 0.001) and sinus protrusion (OR 7.0, 95% CI 1.7-28.5, p = 0.007). Cyst volume ≥ 270 mL was also associated with suboptimal response in the long-term follow-up (OR 4.6, 95% CI 1.3-16.9, p = 0.021). When radiomics features were combined, the area under the curve increased from 0.83 to 0.86 and from 0.68 to 0.82 to predict suboptimal response in short-term and long-term follow-ups, respectively. CONCLUSION Greater estimated volume, sinus protrusion, and radiomics features of the cysts in pretreatment CT can help predict suboptimal response of renal cyst after sclerotherapy.

The Safety and Efficacy of Hepatic Transarterial Embolization Using Microspheres and Microcoils in Patients with Symptomatic Polycystic Liver Disease. J Pers Med 2022; 12:jpm12101624. [PMID: 36294764 PMCID: PMC9605116 DOI: 10.3390/jpm12101624] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2022] [Revised: 09/06/2022] [Accepted: 09/11/2022] [Indexed: 11/06/2022] Open
Abstract
Purpose: We investigated the long-term safety and efficacy of hepatic transarterial embolization (TAE) in patients with symptomatic polycystic liver disease (PLD). Materials and Methods: A total of 26 patients were included, mean age of 52.3 years (range: 33−78 years), undergoing 32 TAE procedures between January 2012 and December 2019 were included in this retrospective study. Distal embolization of the segmental hepatic artery was performed with 300−500 µm embolic microspheres associated with proximal embolization using microcoils. The primary endpoint was clinical efficacy, defined by an improvement in health-related quality of life using a modified Short Form-36 Health Survey and improvement in symptoms (digestive or respiratory symptoms and chronic abdominal pain), without invasive therapy during the follow-up period. Secondary endpoints were a decrease in total liver volume and treated liver volume and complications. Results: Hepatic embolization was performed successfully in 30 of 32 procedures with no major adverse events. Clinical efficacy was 73% (19/26). The mean reduction in hepatic volume was −12.6% at 3 months and −27.8% at the last follow-up 51 ± 15.2 months after TAE (range: 30−81 months; both ps < 0.01). The mean visual analog scale pain score was 5.4 ± 2.8 before TAE and decreased to 2.7 ± 1.9 after treatment. Three patients had minor adverse events, and one patient had an adverse event of moderate severity. Conclusion: Hepatic embolization using microspheres and microcoils is a safe and effective treatment for PLD that improves symptoms and reduces the volume of hepatic cysts.

Perioperative characteristics, histologic diagnosis, complications, and outcomes of dogs undergoing percutaneous drainage, sclerotherapy or surgical management of intrarenal cystic lesions: 18 dogs (2004-2021). BMC Vet Res 2022; 18:233. [PMID: 35718776 PMCID: PMC9208150 DOI: 10.1186/s12917-022-03327-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2022] [Accepted: 05/18/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Canine intrarenal cystic lesions (ICLs) are infrequently reported in the veterinary literature. Several treatment options have been described including cyst fenestration (partial nephrectomy/deroofing) +/- omentalization, sclerotherapy using alcohol as a sclerosing agent, percutaneous cyst drainage (PCD), and ureteronephrectomy. Information regarding presenting clinical signs, physical examination findings, histologic diagnosis and outcomes of dogs with ICLs treated by different methods is limited. Medical records of 11 institutions were retrospectively reviewed to identify dogs that underwent PCD, sclerotherapy, surgical deroofing +/- omentalization, or ureteronephrectomy for management of ICLs from 2004 to 2021. Six weeks postoperative/post-procedural follow-up was required. Cases suspected to represent malignancy on preoperative imaging were excluded. The study objective was to provide information regarding perioperative characteristics, complications, and outcomes of dogs undergoing treatment of ICLs. RESULTS Eighteen dogs were included, with 24 ICLs treated. Ten had bilateral. There were 15 males and 3 females, with crossbreeds predominating. PCD, sclerotherapy, deroofing and ureteronephrectomy were performed in 5 (5 ICLs treated), 7 (11 ICLs), 6 (6), and 7 (7) dogs, respectively, with 5 dogs undergoing > 1 treatment. Seven dogs experienced 8 complications, with requirement for additional intervention commonest. PCD, sclerotherapy and deroofing resulted in ICL resolution in 0/5, 3/11 and 3/6 treated ICLs, respectively. Histopathology identified renal cysts (RCs) in 7/13 dogs with histopathology available and neoplasia in 6/13 (4 malignant, 2 benign). Of 5 dogs diagnosed histopathologically with neoplasia, cytology of cystic fluid failed to identify neoplastic cells. Among 7 dogs with histologically confirmed RCs, 4 had concurrent ICLs in ipsilateral/contralateral kidney, compared with 2/6 dogs with histologically confirmed neoplasia. CONCLUSIONS Benign and neoplastic ICLs were approximately equally common and cystic fluid cytology failed to differentiate the 2. Among renal-sparing treatments, deroofing most commonly resulted in ICL resolution. Presence of concurrent ICLs in ipsilateral/contralateral kidney does not appear reliable in differentiating benign from malignant ICLs.

Abstract
Background: Standard treatments for nonparasitic hepatic cysts (NPHCs) include laparoscopic deroofing (LD), percutaneous aspiration, and alcohol sclerotherapy. However, these treatments have limitations. LD and alcohol sclerotherapy, for example, fail to prevent NPHC recurrences, although alcohol sclerotherapy is satisfactorily effective in treating small cysts (diameter <5 cm), which do not usually need treatment. The present study introduces a novel surgical procedure, laparoscopic enucleation with intact cyst (LEIC), which may prevent postoperative cyst recurrence. Materials and Methods: In this study, we enrolled 14 patients, with NPHCs larger than 9 cm in diameter, who underwent LEIC. Dissection and coagulation were performed using the harmonic shear enucleation and bipolar coagulation techniques. We attempted to completely remove the cysts intact. Results: For all patients, symptoms disappeared after complete elimination of the cyst capsule. No complications (hemorrhage or bile leakage) were found during the perioperative period. The mean follow-up period was 19.3 months (range 10-38 months), during which no recurrences or complications were noted. Conclusions: LEIC is a novel surgical approach that shows satisfactory efficacy and safety in patients with large, surficial, and symptomatic NPHCs. LEIC's main advantage is that it can efficiently prevent cyst recurrence and decrease postoperative morbidity. However, its long-term efficacy and safety require further verification, especially with huge cysts.

A Painless and Time-Saving Modified Technique for Simple Renal Cyst Treatment with Single-session Ethanol Sclerotherapy. Sci Rep 2020; 10:5019.

Abstract
Percutaneous puncture ethanol sclerotherapy is a simple, effective, minimally invasive, and inexpensive procedure to manage symptomatic simple renal cysts. We modified specific technical aspects to balance certain potential intraprocedural factors for ensuring minimal procedural pain and duration as well as maximal clinical therapeutic effects and evaluated the safety and efficacy of this modified technique. A total of 84 eligible patients underwent computed tomography-guided single-session ethanol sclerotherapy using the conventional (group A) or modified (group B) technique. In group B, the puncture route was modified from tansparenchymal to direct for reducing renal injury, and preinjection of low-dose intracystic lidocaine was used to control distending pain caused by ethanol injections; therefore, greater ethanol volumes could be injected for improving the resistance and contact of ethanol with the cyst wall, precluding the need for patient repositioning multiple times to decrease procedural duration. Visual analog scale score for pain and procedural time were significantly higher in group A than in group B. The complication rate was slightly higher in group A than in group B, but the success rate was comparable between the two groups. These results suggest that the modified technique is painless, time-saving, and injury-reducing and can thus improve medical care.

Abstract
Background: Percutaneous aspiration with sclerotherapy (PAS) and laparoscopic marsupialization (LM) are minimally invasive treatment modalities for renal cysts. We aimed to compare the efficacy and cost/effectiveness of LM and PAS for the treatment of simple symptomatic renal cysts. Methods: Data were prospectively collected from three health care institutions in which 80 patients with symptomatic simple renal cysts underwent a single session of PAS with 95% ethanol (PAS group, n = 40) or underwent LM under general anesthesia (LM group, n = 40) between March 2012 and May 2016. We compared the patient profile, duration of procedure, duration of hospital stay, radiological and symptomatic success rates, treatment costs, and incidence of complications between the two groups. Results: At the 6-month follow-up, the radiological success rate in the LM group was significantly greater than that in the PAS group (97.5% versus 60%; P < .001). The symptomatic success rate was comparable in the two groups (95% versus 90%; P = .675). The treatment failure rate did not significantly differ between the two groups (5.0% versus 17.5%, P = .154). The mean total cost in the PAS and LM groups was 1256 USD and 2343 USD, respectively (P = .001). No significant between-group difference was noted regarding the overall complication rate (P = .615). Conclusions: Both LM and PAS are effective and safe procedures for the treatment of symptomatic simple renal cysts. A single session of PAS seems to be a cost-effective method for the management of symptomatic simple renal cysts.

Abstract
Background and Objectives Ethanol retention therapy (ERT) under EUS guidance or a percutaneous approach is a safe treatment for large symptomatic hepatic cysts. However, reports on the long-term outcomes after ERT are very rare. Therefore, we aimed to evaluate the long-term outcomes of ERT in symptomatic large hepatic cysts. Materials and Methods A total of 47 consecutive patients with large symptomatic hepatic cysts treated at the Asan Medical Center from April 2009 to October 2017 were analyzed. Thirty patients with right hepatic cysts were treated with ERT through a percutaneous approach, and 14 patients with left hepatic cysts were treated with ERT under EUS guidance. Three patients were treated with ERT using both methods. Results Of the 47 patients, 43 (91%) showed complete regression and four (9%) showed partial regression on abdominal computed tomography. Recurrence of the cysts was not observed during the follow-up surveillance of a median of 66 months. Conclusions Percutaneous catheter drainage-guided ERT and EUS-guided ERT, based on their favorable long-term outcomes, may be considered as first-line treatments in patients with large symptomatic hepatic cysts.

Abstract
Rationale & Objective Autosomal dominant polycystic kidney disease (ADPKD) is the most common inherited kidney disorder. Progressive increase in cyst number and size leads to kidney failure in a majority of patients. Large kidney cysts, although few, can be especially deleterious by impeding kidney blood flow and obstructing urine flow over a large region. Foam sclerotherapy is a minimally invasive procedure that may be used to ablate large cysts. We examined the effectiveness and safety of foam sclerotherapy for kidney volume reduction in patients with ADPKD. Study Design Prospective cohort study. Setting & Participants Adults with ADPKD at a tertiary referral center in Toronto. Predictor Foam sclerotherapy. Outcomes Volume of treated kidneys and adverse events. Analytical Approach Treated and nontreated kidney volume, kidney function, tolerability, and symptoms were analyzed within each patient. Results We performed 77 foam sclerotherapy treatment sessions in 66 patients. Foam sclerotherapy was associated with a 21.8% volume reduction of the treated kidneys (n = 95; median, 1,138 [IQR, 801-1,582] mL before vs 891 [IQR, 548-1,450] mL after; P < 0.001), while the volume of the nontreated kidneys increased by 3.4% during the same time frame (n = 37; median, 655 [IQR, 352-998] mL before vs 677 [IQR, 371-1,164] mL after; P < 0.001). 4 (6%) patients had a higher measured creatinine clearance by at least 10 mL/min at least 12 months after foam sclerotherapy. 9 (14%) patients experienced self-limiting pain at the procedure site and 2 (3%) had cyst or urinary tract infection. Most patients with flank/back pain, abdominal pain, and abdominal distension had improvement in their symptoms. Limitations Small sample, observational data. Conclusions Foam sclerotherapy is a safe and effective procedure for kidney volume reduction and amelioration of compressive symptoms in select patients with ADPKD. Further studies are needed to assess its effects on kidney blood flow and kidney function and determine the subgroups of patients most likely to benefit.

Abstract
Background Over the past decades, multiple approaches to aspiration sclerotherapy of large symptomatic hepatic cysts have been investigated. However, comparative data are scarce. Objective The objective of this article is to compare cyst reduction, symptomatic relief, and adverse events between ethanol sclerotherapy and polidocanol sclerotherapy. Methods This retrospective study included adults having a symptomatic hepatic cyst treated at a European tertiary referral center with ethanol sclerotherapy (Center 1) or polidocanol-sclerotherapy (Center 2). We compared cyst diameter reduction (%) and symptom improvement (yes/no) within 12 months’ post-treatment between centers using multivariate regression analyses adjusted for confounding factors. Finally, we compared adverse events using Fisher’s exact test. Results We included 71 patients from Center 1 and 66 patients from Center 2 (median age 57 years; 126/137 (92%) female). Cyst reduction was comparable between Centers 1 and 2: 37.5% (IQR 15.7–61.0%) versus 44.2% (IQR 24.6–60.5%), respectively (p = 0.35). Correspondingly, symptomatic relief was comparable: 30/53 (56.6%) versus 43/66 (65.2%), respectively (p = 0.88). Center 1 reported significantly more (11 versus 3; p = 0.047) adverse events than Center 2. Conclusion We found comparable cyst reduction and symptomatic relief rates between ethanol- and polidocanol sclerotherapy, while adverse events occurred more often in the ethanol group. Prospective studies focused on clinical response are needed to further explore differences between approaches.

Pasireotide does not improve efficacy of aspiration sclerotherapy in patients with large hepatic cysts, a randomized controlled trial. Eur Radiol 2018; 28:2682-2689. [PMID: 29318424 PMCID: PMC5938297 DOI: 10.1007/s00330-017-5205-1] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2017] [Revised: 10/28/2017] [Accepted: 11/22/2017] [Indexed: 01/13/2023]
Abstract
OBJECTIVES We tested whether complementary use of the somatostatin analogue pasireotide would augment efficacy of aspiration sclerotherapy of hepatic cysts. METHODS We conducted a double-blind, placebo-controlled trial in patients who underwent aspiration sclerotherapy of a large (>5 cm) symptomatic hepatic cyst. Patients were randomized to either intramuscular injections of pasireotide 60 mg long-acting release (n = 17) or placebo (sodium chloride 0.9 %, n = 17). Injections were administered 2 weeks before and 2 weeks after aspiration sclerotherapy. The primary endpoint was proportional cyst diameter reduction (%) from baseline to 6 weeks. Secondary outcomes included long-term cyst reduction at 26 weeks, patient-reported outcomes including the polycystic liver disease-questionnaire (PLD-Q) and safety. RESULTS Thirty-four patients (32 females; 53.6 ± 7.8 years) were randomized between pasireotide or placebo. Pasireotide did not improve efficacy of aspiration sclerotherapy at 6 weeks compared to controls (23.6 % [IQR 12.6-30.0] vs. 21.8 % [9.6-31.8]; p = 0.96). Long-term cyst diameter reduction was similar in both groups (49.1 % [27.0-73.6] and 45.6 % [29.6-59.6]; p = 0.90). Mean PLD-Q scores improved significantly in both groups (p < 0.01) without differences between arms (p = 0.92). CONCLUSIONS In patients with large symptomatic hepatic cysts, complementary pasireotide to aspiration sclerotherapy did not improve cyst reduction or clinical response. KEY POINTS • Complementary pasireotide treatment does not improve efficacy of aspiration sclerotherapy. • Cyst fluid reaccumulation after aspiration sclerotherapy is a transient phenomenon. • Aspiration sclerotherapy strongly reduces symptoms and normalizes quality of life.

Predictors of treatment response following aspiration sclerotherapy of hepatic cysts: an international pooled analysis of individual patient data. Eur Radiol 2016; 27:741-748. [PMID: 27180184 PMCID: PMC5209423 DOI: 10.1007/s00330-016-4363-x] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2015] [Revised: 02/29/2016] [Accepted: 04/11/2016] [Indexed: 12/13/2022]
Abstract
Objectives To identify predictive variables of treatment response following aspiration sclerotherapy of large symptomatic hepatic cysts. Methods We collected individual patient data from two tertiary referral centres and included all patients treated with aspiration sclerotherapy of a large (>5 cm), symptomatic hepatic cyst. At six months, clinical response was defined as complete or incomplete. Secondary, suboptimal technical response was defined as lower quartile of cyst reduction. Predictive variables of clinical and technical response were analyzed by logistic regression analysis. Results We included 86 patients (58 ± 10 years; female 90 %). Complete clinical response rate was 55 %. Median cyst diameter and volume reduction were 71 % (IQR 50-87 %) and 98 % (IRQ 88-100 %), respectively. Patients with complete clinical response had a significantly higher cyst reduction compared to incomplete responders (OR 1.02, 95 % CI 1.00-1.04). Aspiration of haemorrhagic cyst fluid (OR 4.39, 95 % CI 1.34-14.39) or a lower cyst reduction at one month (OR 1.06, 95 % CI 1.02-1.10) was associated with a suboptimal technical response at six months. Conclusion Complete clinical response is associated with effective cyst reduction. Aspiration of haemorrhagic cyst fluid or a restricted diameter reduction at one month predicts a suboptimal technical treatment response, however, these variables did not predict symptom disappearance. Key Points • Aspiration sclerotherapy of hepatic cysts shows excellent clinical and technical efficacy. • Optimal clinical responders have a markedly higher cyst reduction. • Haemorrhagic aspirate and a strong fluid reaccumulation predict suboptimal cyst reduction.

Abstract
PURPOSE This study aimed to evaluate the feasibility, safety, and efficacy of ultrasound (US)-guided percutaneous ethanol ablation (PEA) for primary non-parasitic splenic cysts. MATERIALS AND METHODS Between February 2006 and February 2015, 15 patients (4 men and 11 women; mean age, 33 ± 15.3 years; age range, 17-65 years) with primary non-parasitic splenic cysts were treated with US-guided PEA. 99.5% absolute ethanol in an amount of approximately 50%-100% of the aspirated volume was injected into each cyst and no more than 240 mL. Standard laboratory tests (hemogram, coagulation, serum, and biochemical tumor marker levels) were performed before and after PEA. RESULTS The median follow-up time was 18.7 months (range 2.8-59.2 months). During follow-up, seven cysts after treatment had disappeared completely, while the other eight cysts had decreased significantly in size. The 3-, 6-, 12-, and 24-month volume reduction rates were 49.7%, 87.6%, 94.3%, and 96.7%. Serum tumor marker CA19-9 levels significantly decreased. Mild adverse reactions included moderate pain in four (26.7%), unbearable pain in one (6.67%), fever in two (13.3%) and slight intracystic bleeding in one (6.67%). There were no serious complications. CONCLUSION US-guided PEA appears to be a safe and effective minimally invasive technique for management of primary non-parasitic splenic cysts.

Abstract
BACKGROUND EUS-guided and percutaneous lavage therapy for large hepatic cysts can replace surgical drainage. EUS-guided therapy can especially enable the alcohol lavage to be done with a 1-step approach. OBJECTIVE To evaluate the utility of EUS-guidance and percutaneous ethanol lavage therapy. DESIGN Retrospective cohort study. SETTING Tertiary-care referral teaching hospital. PATIENTS Adult patients with large liver cysts who underwent cyst drainage and alcohol ablation between 2009 and 2012. INTERVENTIONS Ethanol lavage via percutaneous and/or EUS-guided approaches. MAIN OUTCOME MEASUREMENTS Feasibility, efficacy, and safety of ethanol lavage. RESULTS Seventeen patients with 19 hepatic cysts were enrolled. The median cyst volume before therapy was 368.9 mL (interquartile range, 195.3-795.9 mL). Ten cysts were drained by the percutaneous approach with a pigtail catheter, and 8 cysts underwent EUS-guided aspiration and lavage treatment. In 1 case, both the percutaneous approach and EUS-guided puncture were used. During the median 11.5-month follow-up of the percutaneous approach group, the cysts showed 97.5% reduction. During the median 15-month follow-up of the EUS-guided group, the cysts showed nearly 100% reduction. Percutaneous catheter drainage ethanol lavage was more feasible for right-sided larger cysts, whereas the EUS-guided approach was useful for left-sided lobe cysts. LIMITATIONS Single-center retrospective study. CONCLUSION Excellent symptomatic and radiologic responses and long-term results were achieved with percutaneous catheter-guided and EUS-guided ethanol lavage. Ethanol lavage could be considered a primary method of treatment for hepatic cysts given its high degree of technical feasibility and safety.

Abstract
BACKGROUND AND OBJECTIVE The mean Hounsfield value of 99.9% ethanol did get down to -190 Hounsfield units (HU), there was a linear correlation between ethanol concentration and Hounsfield values. We aimed to evaluate whether sclerotherapy with estimated ethanol concentration was helpful in improving the success rate for treatment of symptomatic simple hepatic cysts. METHODS Forty-five patients with 52 symptomatic simple hepatic cysts were enrolled in this study. Twenty-one patients (24 cysts, group A) were treated by sclerotherapy without estimated ethanol concentration and 24 patients (28 cysts, group B) with estimated ethanol concentration. The Chi-square test and Mann-Whitney U test were used to compare the difference in characteristics and treatment outcomes of the subjects between these two groups. RESULTS The mean cyst size before and after treatment were 8.4cm and 2.3cm, respectively, in group A, and 8.2cm and 0.8cm, respectively, in group B. There was no significant difference in the initial size of hepatic cysts between the groups. However, the final size was significantly smaller in group B (P=0.022). The mean ethanol exposure time was 18.3minutes in group B, which was less than that in group A (P<0.001). The success rate was significantly higher in group B (96.4%) than in group A (70.8%) (P=0.03). There were no major complications in either group. CONCLUSION CT-guided sclerotherapy with estimated ethanol concentration yields better results than those without estimated ethanol concentration in the treatment of symptomatic simple hepatic cysts.

Abstract
PURPOSE This study aimed to evaluate the macroscopic and microscopic peritoneal findings after intraperitoneal injection of alcohol in rats. METHODS From January to February 2012, 20 male rats were used in this study: 15 rats received intraperitoneal injection of 0.1 mL 99.9% alcohol (group 1: experiment group) and 5 rats received intraperitoneal injection of 0.1 mL normal saline (group 2: control group). Animals from each group were sacrificed the day after alcohol injection and each week thereafter. Macroscopic and microscopic examinations of the peritonea and abdominal cavity were performed in each rat. RESULTS There was no significant peritoneal abnormality on macroscopic view, except for a whitish-colored parietal peritoneum around the injection site in 3 animals from group 1. In all but 1 of the animals in group 1, mild to moderate peritoneal inflammation or fibrosis was observed 1 and 2 weeks after alcohol injection. However, the peritoneal abnormality of alcohol injection had dissipated by week 3. Peritoneal abnormalities were not observed in group 2. CONCLUSION An intraperitoneal injection of alcohol in rats caused peritoneal inflammation or fibrosis during the first 2 weeks. However, these peritoneal abnormalities were short-lived and had completely disappeared after 3 weeks.

Abstract
OBJECTIVES To describe the long-term clinical and morphological outcome of symptomatic hepatic cysts treated with percutaneous ethanol sclerotherapy (PES). METHODS From December 2003 to September 2011, all patients with hepatic cysts undergoing PES with a follow-up after 12 months were included. Evolution of the volume of the cysts and clinical and biological data were recorded. Features of the cyst were evaluated in each patient: simple, haemorrhagic or developed on underlying polycystic liver disease (PCLD). RESULTS Fifty-eight cysts (median volume 666 mL) were treated in 57 patients (52 women, mean age 58 years (18-80)). Twenty-two patients (39 %) had simple hepatic cysts, 19 (33 %) had dominant cysts on PCLD and 20 had haemorrhagic cysts (34.5 %), including 4 with PCLD. After a mean 27.3 months of follow-up, the final median cystic volume was 13.5 mL (p < 0.0001), and the median reduction in cyst volume was 94 % (58-100 %). Treatment was satisfactory in 95 % of the patients (54/57) (symptoms disappeared in 45/57 (79 %), decreased in 9/57 (16 %)). There was no clinical or morphological difference between patients with PCLD, haemorrhagic cysts or simple cysts. CONCLUSION The clinical and morphological efficacy of a single session of PES is very high, regardless of the presence of intracystic haemorrhage or underlying PCLD. KEY POINTS • The clinical efficacy of percutaneous ethanol sclerotherapy is very high. • Haemorrhagic content should not be a contraindication for percutaneous sclerotherapy. • Dominant cysts on polycystic liver disease should be treated with PES. • Imaging follow-up should not be performed shortly after the procedure.

Abstract
Percutaneous splenic biopsy and drainage are relatively safe and accurate procedures. The risk of major complication (1.3%) following percutaneous splenic biopsy does not exceed that of other solid intra-abdominal organ biopsies, and it has less morbidity and mortality than splenectomy. Both computed tomography and ultrasound can be used to provide image guidance for biopsy and drainage. The safety profile of fine-needle aspiration cytology is better than core needle biopsy, but core biopsy has superior diagnostic accuracy.

Abstract
PURPOSE To evaluate the efficacy and safety of single-session percutaneous needle aspiration and single-injection bleomycin sclerotherapy for the treatment of simple renal cysts. MATERIALS AND METHODS A total of 66 renal cysts in 53 patients were treated by single-session percutaneous needle aspiration and single-injection bleomycin sclerotherapy under computed tomography (CT) guidance. Symptomatic (n = 31) and asymptomatic cysts (n = 22) with maximum diameters greater than 5 cm were treated. As much liquid content of each cyst was aspirated as possible, and bleomycin was injected and remained in the cyst. Follow-up was performed with ultrasonography or CT every 3 months until 1 year, and cyst volume was calculated before and after sclerotherapy. Therapeutic response was assessed by cyst volume reduction rate (VRR) and classified as complete regression (CR; ie, invisible), near-CR (ie, VRR>85%), partial regression (PR; ie, VRR of 50%-85%), or no response (NR; ie, VRR<50%). Medical records were reviewed to analyze complications. RESULTS Cysts refilled partially in the initial stage after sclerotherapy and decreased gradually in size over the entire follow-up period. At 1-year follow-up, the overall response rate was 98.5% (65 of 66), with CR in 31 cysts (47.0%), near-CR in 24 cysts (36.4%), PR in 10 cysts (15.1%), and NR in one cyst (1.5%). No major complications were encountered. CONCLUSIONS Single-session percutaneous needle aspiration and single-injection bleomycin sclerotherapy is a simple, safe, effective, well tolerated alternative technique for management of simple renal cysts.

Abstract
BACKGROUND Liver cysts are common, occurring in up to 5% of the population. For many types of cysts, a variety of different treatment options exist and the preferred management is unclear. METHODS A PubMed and Medline literature review was undertaken and articles pertaining to the diagnosis and management of cystic lesions within the liver were retrieved. RESULTS Therapy for symptomatic cysts may incorporate aspiration with sclerotherapy or de-roofing. Polycystic liver disease presents a unique management problem because of the high morbidity and mortality rates from intervention and high rates of recurrence. Careful patient counselling and assessment of symptom index is essential before embarking on any treatment. New medical treatments may ameliorate symptoms. Acquired cystic lesions in the liver require a thorough work-up to fully characterize the abnormality and direct appropriate treatment. Hydatid cysts are best treated by chemotherapy, followed by some form of surgical intervention (either aspiration and sclerotherapy or surgery). Liver abscesses can be effectively treated by aspiration or drainage. CONCLUSION All patients with cystic lesions in the liver require discussion at multidisciplinary meetings to confirm the diagnosis and determine the most appropriate method of treatment.

Abstract
BACKGROUND Liver cysts are common, occurring in up to 5% of the population. For many types of cysts, a variety of different treatment options exist and the preferred management is unclear. METHODS A Pubmed and Medline literature review using key words non-parasitic hepatic cysts, polycystic liver disease, echinococcus, hydatid cysts parasitic cysts, Caroli's disease, cystadenoma; liver abscess, surgery, aspiration and treatment was undertaken and papers pertaining to the diagnosis and management of cystic lesions within the liver were retrieved. RESULTS Asymptomatic simple cysts in the liver require no treatment. Therapy for symptomatic cysts may incorporate aspiration with sclerotherapy or de-roofing. At present, insufficient evidence exists to recommend one over the other. Polycystic liver disease presents a unique management problem because of high morbidity and mortality rates from intervention and high rates of recurrence. Careful patient counselling and assessment of symptom index is essential before embarking on any treatment. New medical treatments may ameliorate symptoms. Acquired cystic lesions in the liver require a thorough work-up to fully characterize the abnormality and direct appropriate treatment. Hydatid cysts are best treated by chemotherapy followed by some form of surgical intervention (either aspiration and sclerotherapy or surgery). Liver abscesses can effectively be treated by aspiration or drainage. With improved antimicrobial efficacy, prolonged treatment with antibiotics may also be considered. CONCLUSION All patients with cystic lesions in the liver require discussion at multi-disciplinary meetings to confirm and the diagnosis and determine the most appropriate method of treatment.

Abstract
PURPOSE OK-432 is known to be a potent sclerosant of cystic lesions. The purpose of this study was to evaluate both its safety and pathologic effects after the infusion of OK-432 into the peritoneal cavity of rats. MATERIALS AND METHODS Twenty male rats were used in this study. Twelve rats were infused intraperitoneally with 0.2 Klinishe Einheit of OK-432 melted in 2 mL of normal saline (group 1: the treated group); four rats each were infused intraperitoneally with 0.5 mL of 99% ethanol (group 2) and normal saline (group 3), and served as the control groups. An abdominal ultrasonographic examination was performed both before and after the infusions in all rats. Three rats in group 1 and one rat in each of groups 2 and 3 were sacrificed each week following the infusion. Gross and microscopic evaluations of the peritoneum and abdominal cavity were performed on each rat. RESULTS In group 1, the abdomen was clear on gross inspection and the peritoneum was unremarkable on microscopic examination. In group 2, mild-to-moderate peritoneal adhesions were revealed grossly, and inflammation and fibrosis of the peritoneum were demonstrated microscopically. In group 3, no specific abnormalities were noted on gross or microscopic examinations. CONCLUSION Leakage or abnormal infusion of OK-432 solution into the peritoneal cavity during sclerotherapy of intra-abdominal or retroperitoneal cystic lesions does not result in any significant complications.
