BACKGROUND: Laparoscopic hepatectomy is a common procedure that has been reported frequently [1-3]. However, laparoscopic resection of tumors located in hepatic segments 5 and/or 8 remains a technically difficult procedure as it requires two transection planes [4]. Furthermore, there are a greater number of hepatic vein and glissonian pedicle branches that require a division as compared to other hepatectomy operations. In this report, we present a pure laparoscopic right anterior sectionectomy (RAS) for hepatocellular carcinoma (HCC)...

BACKGROUND: Although energy devices have brought big advantages to surgery, there are few reports about disadvantages. We conducted an animal experiment to clarify the thermal effect of the bipolar tissue sealing system, Enseal™, to adjacent vessels of the inferior vena cava. METHODS: We used an experimental miniature pig for the experiment. After laparotomy and mobilization of the intestine, the inferior vena cava was exposed. We activated the device under two different conditions: In the first group, the so-called contact group (Group C), the blade of Enseal™ touched the surface of the IVC directly...

STUDY OBJECTIVE: To demonstrate the feasibility of laparoscopic single-incision myomectomy using new technology. DESIGN: A step-by-step video demonstrating our technique for accomplishing a laparoscopic single-site myomectomy of a large intramural myoma. SETTING: Single institution. INTERVENTIONS: Single-incision laparoscopic surgery (SILS) has been shown to have similar outcomes to multiport laparoscopy but with superior cosmetic results [1,2] but has traditionally been associated with an increased learning curve, primarily because of poor ergonomics and instrument collisions, lack of triangulation, and, until recently, inadequate instrumentation...

Accurate division and sealing of lung parenchyma particularly in cases of total or near total incomplete fissure are crucial for preventing air leakage following thoracoscopic pulmonary lobectomy (TPL). However, conventional endoscopic stapling devices cannot be used during TPL in small children because of limited space. Consequently, Ligasure (LS) and Enseal (ES) devices are being used instead. We are the first to compare LS and ES for efficacy and efficiency during TPL. Of 26 TPL (6 upper, 3 middle, and 17 lower) performed for congenital adenomatoid malformation (n = 16) and sequestration (n = 10), incomplete fissure was found in 14...

OBJECTIVES: Vessel-sealing devices (VSDs) are widely used for various surgical procedures, including thoracoscopic surgery, but very few reports have compared their safety and usefulness with human thoracoscopic lobectomy procedures not employing VSDs. METHODS: Primary lung cancer patients for whom a thoracoscopic lobectomy involving mediastinal lymph node dissection was planned in our department from April 2011 to March 2013 were recruited for the study. Patients were randomly allocated to a control group (n = 14) or a VSD group (n = 44), which comprised three sub-groups, namely EnSeal (n = 17), LigaSure (n = 15) and Harmonic (n = 12)...

Minimally invasive surgery (MIS) has become the standard of care for a variety of surgical conditions, and reliable vessel sealing and precise cutting are essential. A variety of tissue-sealing devices have been used successfully to decrease operating time and control bleeding during hysterectomy and other MIS gynecologic procedures. One development involves the next generation of advanced bipolar devices by ETHICON (Ethicon Endo-Surgery Inc., Cincinnati, OH), called ENSEAL® G2 Tissue Sealers. Tip improvements to the ENSEAL® have included stronger jaws and a welded positive electrode in the stationary jaw, thus enabling the new ENSEAL® G2 Tissue Sealer to provide reliable vessel sealing and precise cutting all in the same instrument...
