Portable Cyst Extractor: Detecting Cyst Nematodes in the Field

For on-site detection of cysts, a portable cyst extraction kit was constructed from nine readily available items. The portable cyst extractor detected cysts in a range of 1-117 cysts/100 g soil from 42 fields. Samples processed by this kit in fields were clean and easy to examine, possibly because the kit is a compact version of the standard wet-sieving technique used in the laboratory. The portable cyst extractor has several advantages over traditional survey methods: i) diagnosis of cyst infestations in the field accurately and rapidly most of the year and ii) reduction in the labor of samplings and transportation of soil samples.     

Perioperative Challenges and Surgical Treatment of Large Simple,and Infectious Liver Cyst - A 12-Year Experience

Background

Cystic lesions of the liver consist of a heterogeneous group of disorders that can present diagnostic and therapeutic challenges.

Methods

A retrospective review of all medical records of adult patients diagnosed with large (>7 cm) cystic lesions of the liver between January 2000 and December 2011, at Kurume University Hospital. Cases with polycystic disease were excluded.

Results

Twenty three patients were identified. The mean size was 13.9 cm (range, 7-22cm). The majority of simple cysts were found in women (females: males, 2: 21). In 19 patients, the cyst was removed surgically by wide deroofing (laparoscopically in 16 cases, combined with ethanol sclerotherapy in 13 cases). Infection of the liver cyst occurred in one patient, who later underwent central bi-segmentectomy.

Conclusion

Simple large cysts of the liver can be successfully treated by laparoscopic deroofing and alcohol sclerotherapy. Large hepatic cyst considered to need drainage should be removed surgically to avoid possible infection.     

置管引流大剂量乙醇分次硬化治疗肝肾巨大囊肿的新探索

目的：探讨经皮穿刺置管引流及大剂量乙醇分次硬化治疗肝肾巨大囊肿的疗效及安全性。方法选取最大直径≥8 cm肝脏或肾脏巨大囊肿,囊肿患者分为两组,对照组35例,采用PTC针穿刺一次性大剂量无水乙醇囊内冲洗法。研究组38例,采用置管引流分次大剂量无水乙醇冲洗法。两组治疗方法比较术中术后不良反应的发生率。术后随访一年,观察囊肿直径变化并比较两组间的疗效差别。结果置管引流分次硬化治疗组术后疗效优于对照组,术中术后不良反应发生率低于对照组。结论应用置管引流大剂量乙醇分次硬化治疗肝肾巨大囊肿疗效更显著,更安全可靠。
