Laparoscopic Management of a Hydatid Cyst of the Adrenal Gland

Hydatid disease is endemic in parts of India, yet genitourinary involvement is rare. Laparoscopic management of such cases is uncommonly reported. We present a case of an adrenal hydatid and its management by laparoscopic aspiration, instillation of scolicidal solution, and partial excision of the cyst.

Gamma Knife Radiosurgery after Stereotactic Aspiration for Large Cystic Brain Metastases

OBJECTIVE: Several treatment options have proven effective for metastatic brain tumors, including surgery and stereotactic radiosurgery. Tumors with cystic components, however, are difficult to treat using a single method. We retrospectively assessed the outcome and efficacy of gamma knife radiosurgery (GKRS) for cystic brain metastases after stereotactic aspiration of cystic components to decrease the tumor volume. METHODS: The study population consisted of 24 patients (13 males, 11 females; mean age, 58.3 years) with cystic metastatic brain tumors treated from January 2002 to August 2008. Non-small cell lung cancer was the most common primary origin. After Leksell stereotactic frame was positioned on each patient, magnetic resonance images (MRI)-guided stereotactic cyst aspiration and GKRS were performed (mean prescription dose : 20.2 Gy). After treatment, patients were evaluated by MRI every 3 or 4 months. RESULTS: After treatment, 13 patients (54.2%) demonstrated tumor control, 5 patients (20.8%) showed local tumor progression, and 6 patients (25.0%) showed remote progression. Mean follow-up duration was 13.1 months. During this period, 10 patients (41.7%) died, but only 1 patient (4.2%) died from brain metastases. The overall median survival after these procedures was 17.8 months. CONCLUSION: These results support the usefulness of GKRS after stereotactic cyst aspiration in patients with large cystic brain metastases. This method is especially effective for the patients whose general condition is very poor for general anesthesia and those with metastatic brain tumors located in eloquent areas.

Efficacy of transvaginal ultrasound-guided aspiration in benign pelvic cyst / 대한산부인과학회지

OBJECTIVE: We investigated the clinical efficacy and safety of transvaginal ultrasound-guided aspiration in treatment of benign pelvic cyst. METHODS: We analyzed medical records of the 343 women with pelvic cyst who underwent transvaginal ultrasound-guided aspiration between 1996 and 2004. We investigated the age, parity, tentative diagnosis, size of the cyst at short-, and long- term follow up, type of aspiration, character and cytology of the aspirated contents, and complication. RESULTS: Mean diameters were significantly reduced after transvaginal ultrasound-guided aspiration at short-, and long-term follow up in all types of cysts except lymphocele (p<0.05). However, at long-term follow up, the proportions of the cysts that were completely resolved or reduced in size greater than 50% after ultrasound-guided aspiration were only 37%, 24.8%, 28%, and 30% in simple cyst, endometrioma, pseudocyst, and lymphocele, respectively. No serious aspiration related complication was identified except two cases. One was ovarian abscess and the other was bladder puncture during aspiration. CONCLUSION: This study suggests that transvaginal ultrasound-guided aspiration of benign pelvic cyst is a simple and safe procedure, but the application of aspiration to simple cyst, pseudocyst, lymphocele should be prudent because of the limited therapeutic efficacy. But for patients with endometrioma who wish to be pregnant, transvaginal ultrasound-guided aspiration could be a good treatment option to preserve ovarian reserve function.
