PURPOSE: Robotic surgery is known to provide an improved technical ability as compared to laparoscopic surgery. We aimed to compare the efficiency of surgical skills by performing the same experimental tasks using both laparoscopic and robotic systems in an attempt to determine if a robotic system has an advantage over laparoscopic system. METHODS: Twenty participants without any robotic experience, 10 laparoscopic novices (LN: medical students) and 10 laparoscopically-experienced surgeons (LE: surgical trainees and fellows), performed 3 laparoscopic and robotic training-box-based tasks. This entire set of tasks was performed twice. RESULTS: Compared with LN, LEs showed significantly better performances in all laparoscopic tasks and in robotic task 3 during the 2 trials. Within the LN group, better performances were shown in all robotic tasks compared with the same laparoscopic tasks. However, in the LE group, compared with the same laparoscopic tasks, significantly better performance was seen only in robotic task 1. When we compared the 2 sets of trials, in the second trial, LN showed better performances in laparoscopic task 2 and robotic task 3; LE showed significantly better performance only in robotic task 3. CONCLUSION: Robotic surgery had better performance than laparoscopic surgery in all tasks during the two trials. However, these results were more noticeable for LN. These results suggest that robotic surgery can be easily learned without laparoscopic experience because of its technical advantages. However, further experimental trials are needed to investigate the advantages of robotic surgery in more detail.

3.Laparoscopic Extracorporporeal Knot Thying Using an Instrument for Knot Pushing and Tightening.
Journal of the Korean Surgical Society 1997;53(4):470-472
Priciples of kont-tying have assumed a new and enhanced role in operative laparoscopy. The surgeon should be familiar with extracorporeal knot-tying techniques. For extracorporeal knot-tying, a knot pusher is used to properly secure the knot. But a knot pusher has some limitation for tightening of the knot. I developed an instrument which has a slit and hole.(slit for knot pushing and hole for knot tightening) for a secure knot. By using this instrument(Lee's knot presser) it is very easy and secure for knot-tying. The surgeon can confirm and control the knot tightening.

We report a case of a large peritoneal loose body diagnosed on computed tomography. The most common causes of a peritoneal loose body are thought to be torsion and separation of the appendices epiploicae. Peritoneal loose bodies are usually small, 0.5 to 2.5 cm in diameter. However, "giant" peritoneal loose bodies, larger than 4 cm in diameter, are an uncommon disease and present with various symptoms, and are difficult to diagnose preoperatively. Especially, abdominal large peritoneal loose bodies are frequently misdiagnosed as tumorous disease preoperatively. In our case, the loose body appeared as a round pelvic mass with central calcifications and a distinct fat plane separating it from adjacent organs. Preoperatively, we suspected a tumorous lesion from the wall of the upper rectum; however, at laparoscopy, a large peritoneal loose body was detected. An extraction of the giant peritoneal loose body was performed laparoscopically.

Background: Laparoscopic cholecystectomy is the first laparoscopic surgery that was performed at Cho Ray hospital in September 1992. In 2005, Quang Tri general hospital has performed successfully the first case of laparoscopic appendectomy. Objectives: To access the preliminary results of application on endoscopic surgery in Quang Tri general hospital. Subjects and method: A prospective study was conducted on 140 patients with laparoscopic surgery or retroperitoneal surgery, was performed in Quang Tri general hospital from September, 2005 to April, 2006. Results:Among 140 patients was operated, there was only one case of postoperative intestinal obstructive complication (accounted for 0.7%), no case of death. Operative aged was between 11 and 70 years old. The average surgical time was 65 minutes for cholecystectomy, 35 minutes for appendectomy, 85 minutes for ureterolithotomy, 80 minutes for gynecological diseases. 2 cases of cholecystectomy and appendectomy changed open surgery. Conclusion: Laparoscopic surgery is a safe and effective method. It can be developed in provincial hospitals. Quang Tri general hospital has successful preliminary developed the new technique.

Objective: Various techniques and instruments have been
developed to provide safe and secure closure of
laparoscopic wounds. Herein we describe a simple method
to close laparoscopic supraumbilical wounds with the aid of
a laparoscopic port.
Method: This was a retrospective review of prospective data,
which were from 151 patients who underwent laparoscopic
cholecystectomy for symptomatic gallstone disease from
December 2009 to December 2010 in Sultanah Bahiyah
Hospital. A senior consultant hepato-pancreato-biliary (HPB)
surgeon and two HPB trainee surgeons performed the
operations. Postoperatively, all patients were followed up at
4 weeks.
Results: All patients successfully underwent closure of the
supraumbilical wound with the assistance of a 5mm
laparoscopic port. None of the patients had incisional hernia
on follow up.
Conclusion: Port assisted closure of supraumbilical
laparoscopic wounds is a feasible and safe technique.

Presence of a hypofunctioning pigmented adenoma are commonly asymptomatic and is usually only found during an autopsy. In contrast, hyperfunctioning pigmented adenoma is a rare clinical entity and in the majority of cases results in Cushing‟s syndrome. In this case study, we report a 66-year-old male who presented instead with the clinical and biochemical features of Conn‟s syndrome. On laparoscopic adrenalectomy, it was found that the tumour had a functioning black adenoma which does not usually present with Conn‟s syndrome but rather to that of a Cushing‟s. The intraoperative changes and histopathological findings are discussed.
