Long-term safety and efficacy of ethanol retention therapy via percutaneous approach and/or EUS guidance for symptomatic large hepatic cysts (with video)

Symptomatic hepatic cyst treated with endoscopic ultrasound-guided drainage and minocycline hydrochloride injection: a case report

A 72 year-old male patient with a history of a hepatic cyst presented to our hospital with epigastric pain. The cyst had enlarged to approximately 130 mm and was diagnosed as a symptomatic hepatic cyst. Percutaneous cyst drainage was deemed challenging because of the risk of intestinal perforation; therefore, transgastric endoscopic ultrasound-guided hepatic cyst drainage was performed with external nasal cyst drainage. After cyst shrinkage was confirmed, minocycline hydrochloride was injected into the cyst through the nasal drainage tube, and the nasal cyst drainage was removed. Nine months after treatment, the cyst diameter markedly reduced to 12 mm on computed tomography, and the symptoms improved. In cases where surgery is complex or it is difficult to secure a percutaneous puncture line, endoscopic ultrasound-guided drainage and minocycline hydrochloride injection may be effective if a puncture route can be secured under endoscopic ultrasound.

A safe and effective endoscopic treatment method for simple hepatic cysts (with video)

Background and study aims Symptomatic simple hepatic cysts require treatment, with several guidelines recommending laparoscopic deroofing. However, cysts located in the posterosuperior segments are considered poor candidates for this procedure. Gastrointestinal endoscopes are more flexible and able to reach less accessible areas than laparoscopes. This study aimed to evaluate the utility of endoscopic transgastric hepatic cyst deroofing (ETGHCD) for treatment of simple hepatic cysts. Patients and methods Seven patients with simple hepatic cysts were evaluated between June 2021 and October 2023. The success rate, procedure time, post-procedure length of hospital stays, complications, pathologic diagnosis, and efficacy were recorded. Results Eleven cysts in seven patients (5 men; mean age 65.5 (standard deviation [SD] 8.5) years) were successfully treated without any complications. The mean procedure time was 65.6 minutes (SD 17.2). Mean post-procedure hospitalization was 4.4 days (SD 1.0). The pathologic diagnosis of 11 cysts showed simple hepatic cysts. The size of the cysts was significantly decreased from 337.0 cm 3 (SD 528.8) to 5.2 cm 3 (SD 6.3) 1 month after ETGHCD. During the median 12.7-month follow-up in seven patients, the cysts showed a 99.6% reduction with no recurrence. Conclusions ETGHCD provided a feasible, safe, effective, and minimal invasive alternative approach for the treatment of simple hepatic cysts.

Comparison of endoscopic ultrasound-guided drainage and percutaneous drainage combined with minocycline sclerotherapy for symptomatic hepatic cysts: A retrospective study

Simple hepatic cysts (SHC) are generally asymptomatic and incidentally diagnosed using imaging studies. Asymptomatic SHC does not require treatment, but symptomatic SHC warrants treatment using different modalities, including intravenous antibiotic therapy, ultrasound-guided percutaneous catheter drainage (PCD) with sclerotherapy, and surgery. The dissemination of endoscopic ultrasonography (EUS) intervention techniques has enabled the performance of puncture and drainage via the transgastrointestinal route for intra-abdominal abscesses. Despite the development of an EUS-guided drainage method for treating symptomatic SHC, only a few case reports using this method have been reported. This study retrospectively analyzed the safety and feasibility of EUS-guided drainage of symptomatic SHC as well as its clinical outcomes and compared it with combined therapy using PCD and minocycline sclerotherapy. The records of 10 consecutive patients with 11 symptomatic SHCs treated with either EUS-guided drainage or PCD combined with minocycline sclerotherapy at the Musashino Tokushukai Hospital from August 2019 to January 2024 were retrospectively examined. All cases in both groups achieved technical and clinical success, with no reported adverse events. The median reduction rates of the major cyst diameters in the EUS-guided drainage and PCD with sclerotherapy groups were 100% (interquartile range [IQR]: 94%-100%) and 67% (IQR: 48.5%-85%). The length of hospital stay was 7 and 22.5 days in the EUS-guided and PCD with sclerotherapy groups (P = .01). EUS-guided drainage of symptomatic SHC is a safe and effective therapeutic alternative to percutaneous drainage with sclerotherapy and surgery for treating symptomatic SHC.

Laparoscopic Approach to Primary Splenic Cyst: Case Report and Review of the Literature

Splenic cysts are rare benign lesions of the spleen, often asymptomatic and incidentally discovered during imaging studies. While many splenic cysts remain asymptomatic and do not require intervention, surgical management becomes essential in cases of symptomatic cysts, large cysts, or when malignancy cannot be ruled out. Laparoscopic surgery has emerged as a minimally invasive and effective approach for treating splenic cysts, offering advantages such as shorter hospital stays, reduced postoperative pain, and faster recovery. In this case report, we describe our experience with laparoscopic surgery for a symptomatic splenic cyst in a young patient.

Liver cyst with biliary communication treated with endoscopic ultrasound-guided drainage: A case report

RATIONALE

Simple liver cysts are common, and usually benign and asymptomatic, requiring little to no treatment. Liver cysts with biliary communication, however, are rare and require effective treatment to avoid recurrence.

PATIENT CONCERNS

A 70-year-old woman with breast cancer visited our hospital for treatment. Physical examination revealed abdominal distension and bilateral lower leg edema.

DIAGNOSIS

Abdominal contrast-enhanced computed tomography revealed a giant liver cyst, inducing inferior vena cava compression that was causing her edema.

INTERVENTIONS

Percutaneous transhepatic cyst drainage was performed. Since the bilirubin level in the drained fluid was high, the patient was diagnosed with a liver cyst with biliary communication. After the procedure, her symptoms improved and the cyst decreased in size. However, the drainage volume did not decrease after approximately 2 weeks. Sclerotherapy with minocycline was ineffective. Thus, endoscopic retrograde cholangiopancreatography was performed, and an endoscopic nasobiliary drainage tube was inserted. The percutaneous drainage tube was clamped, and the cyst showed increase in size. Therefore, endoscopic ultrasound-guided cyst drainage, which is less invasive than surgery, was performed.

OUTCOMES

The cyst tended to decrease in size even after the percutaneous drainage tube had been removed. At 3years follow-up, the cyst has almost disappeared.

LESSONS

Endoscopic ultrasound-guided drainage can treat liver cyst with biliary communication.

Endoscopic ultrasound in chronic liver disease

Endoscopic ultrasound (EUS) is a minimally invasive diagnostic and therapeutic modality with a number of established as well as evolving uses in patients with chronic liver disease. Compared to other diagnostic tools such as cross-sectional imaging or conventional endoscopy, EUS has been shown to increase diagnostic sensitivity and therapeutic success for many clinical scenarios and applications with a low rate of adverse events. In this review, we discuss and focus on the current and growing role of EUS in the evaluation and/or treatment of hepatobiliary masses, hepatic parenchymal disease, portal hypertension, esophageal and other varices, and indeterminate biliary strictures.
