Among treatment modalities for unresectable hepatocellular carcinoma (HCC), radiofrequency ablation (RFA) is getting popular due to low morbidity and its effectiveness. However, when the tumor is located just under the diaphragm, a percutaneous approach for RFA is often impossible because of the difficulty in visualizing the tumor with conventional ultrasonographic examination. ⋯ Dual-scope guided (simultaneous thoraco-laparoscopic) transthoracic transdiaphragmatic intraoperative RFA is an easy, safe, and effective minimal invasive modality for treatment of the selective patient with HCC, with liver cirrhosis, which is located immediately under the diaphragm. Further experiences and a long term follow up is mandatory.

Comparative Study
Comparison of four energy-based vascular sealing and cutting instruments: A porcine model.
To compare the safety and efficacy of four energy-based vascular sealing and cutting instruments. ⋯ The bursting pressures with EnSeal were significantly higher than with all the other instruments. Harmonic ACE was the fastest sealing instrument and LigaSure Atlas was slowest. EnSeal created less radial thermal damage to the adventitial collagen of the vessels and LigaSure Atlas created less thermal damage to the media of the vessels. The clinical significance of these findings is unknown.

To determine the best timing for thoracoscopic drainage of clotted hemothorax in order to ensure safe and effective results and to identify risk factors associated with drainage failure. ⋯ Videothoracoscopy must be considered the procedure of choice for the treatment of retained post-traumatic hemothorax. It is a safe and effective procedure allowing the successful treatment of up to 73.4% of patients. Best results are obtained when drainage is performed within the first five days after trauma.

Randomized Controlled Trial Comparative Study
Laparoscopic fundoplication: Nissen versus Toupet two-year outcome of a prospective randomized study of 200 patients regarding preoperative esophageal motility.
To determine the influence of preoperative esophageal motility on clinical and objective outcome of the Toupet or Nissen fundoplication and to evaluate the success rate of these procedures. Nissen fundoplication (360 degrees ) is the standard operation in the surgical management of gastroesophageal reflux disease (GERD). In order to avoid postoperative dysphagia it has been proposed to tailor antireflux surgery according to pre-existing esophageal motility. Postoperative dysphagia is thought to occur more commonly in patients with esophageal dysmotility and it has been recommended to use the Toupet procedure (270 degrees ) in these patients. We performed a randomized trial to evaluate this tailored concept and to compare the two operative techniques concerning reflux control and complication rate (dysphagia). ⋯ Tailoring antireflux surgery according to the esophageal motility is not indicated, as motility disorders are not correlated with postoperative dysphagia. The Toupet procedure is the better operation as it has a lower rate of dysphagia and is as good as the Nissen fundoplication in controlling reflux.

Comparative Study
Postoperative hypoesthesia and pain: qualitative assessment after open and laparoscopic inguinal hernia repair.
Chronic pain is an important outcome variable after inguinal hernia repair that is generally not assessed by objective methods. The aim of this study was to objectively investigate chronic pain and hypoesthesia after inguinal hernia repair using three types of operation: open suture, open mesh, and laparoscopic. ⋯ The incidence of hypoesthesia in patients who had laparoscopic hernia repair is significantly lower than in those who had open hernia repair. Hypoesthesia after laparoscopic but not after open repair is significantly associated with postoperative pain. Von Frey monofilaments are important tools for the assessment of inguinal hypoesthesia and pain in patients who had inguinal hernia repair allowing quantitative and qualitative comparison between various surgical techniques.
