Abstract

Minimally invasive techniques have revolutionized operative surgery. Computer aided surgery and robotic surgical systems strive to improve further on currently available minimally invasive surgery and open new horizons. Only several centers are currently using surgical robots and publishing data. In gastrointestinal surgery, robotic surgery is applied to a wide range of procedures, but is still in its infancy. Cholecystectomy, Nissen fundoplication and Heller myotomy are among the most frequently performed operations. The ZEUS (Computer Motion, Goleta, CA) and the da Vinci (Intuitive Surgical, Mountain View, CA) surgical systems are today the most advanced robotic systems used in gastrointestinal surgery. Most studies reported that robotic gastrointestinal surgery is feasible and safe, provides improved dexterity, better visualization, reduced fatigue and high levels of precision when compared to conventional laparoscopic surgery. Its main drawbacks are the absence of force feedback and extremely high costs. At this moment there are no reports to clearly demonstrate the superiority of robotics over conventional laparoscopic surgery. Further research and more prospective randomized trials are needed to better define the optimal application of this new technology in gastrointestinal surgery.

[Endoscopic resection for early gastric cancers by EMR/ESD].

The key issue in the field of therapeutic endoscopy in recent years is the development of a new therapeutic strategy for early gastric cancers using endoscopic submucosal dissection (ESD) technique. ESD was developed to overcome the problem of remnant or recurrent tumors after incomplete resection by conventional endscopic mucosal resection (EMR). Ever since after the emergence of ESD, indication criteria for endoscopic resection of early gastric cancers were extended through expansion of both theoretical and technical conditions. Complete en bloc resection rates were 96.7% and 62.6% in the ESD group and the EMR group, respectively, in our institution. ESD is a highly effective technique enabling us to resect much larger and difficult lesions, which cannot be resected by conventional EMR techniques. However, it involves a much higher complication rate and requires much higher skills. A small lesion less than 20 mm located in a good position can be resected completely, without any difficulties using conventional EMR techniques. Therefore, we must consider the approach to treatment, when conducting an endoscopic resection,it terms of the situation and skills of the endoscopist.

Laparoscopic excision of duodenal schwannoma.

BACKGROUND: Benign duodenal tumours are rare and less common than malignant tumours. They comprise a wide variety of pathologies. Schwannoma is an ectodermal neoplasm arising from the nerve sheath that envelops axons. A duodenal location is extremely rare. Therapy consists in the radical excision of the tumour. Our aim was to describe a minimally invasive technique used for the excision of duodenal schwannoma, so that a laparotomy has been avoided. METHODS: A laparoscopic operation under general anaesthesia was undertaken with the patient in supine position with the legs abducted. No macroscopic peritoneal seedling was found. Therefore, a laparoscopic Kocher maneuver was performed. The retroperitoneum was entered using the harmonic scalpel and the dissection extended beyond the vena cava and the duodenum. The location and the size of the lesion have been confirmed using an intraoperative endoscopic ultrasound examination. The excision of the lesion was performed by use the harmonic scalpel. Then, the duodenal wall was sutured by use endoscopic stitches. The resected lesion was then placed in a retrieval bag and extracted through the port incision. Operating time was 300 min and blood loss 200 ml. RESULTS: The postoperative course was uneventful. Histological findings showed a benign schwannoma. CONCLUSIONS: The minimally invasive technique may be a valid alternative to open surgery in the treatment of benign duodenal tumors.
