Purpose: The aim of this study was to compare the short-term operative outcomes of laparoscopy-assisted total gastrectomy (LATG) with those of open total gastrectomy (OTG) for patients suffering with advanced upper gastric cancer. Materials and Methods: Of the 47 patients who underwent LATG with $D1+{\beta}$ or D2 lymphadenectomy from July 2004 to March 2008, 29 patients with pathologically proven advanced gastric cancer were compared with 35 patients who underwent conventional OTG during the same time period. The comparison was based on the clinicopathological characteristics, the surgical outcome, the follow-up survival and tumor recurrence. Results: The patients' age, gender and body mass index were similar between the two groups. However, there were statistically differences in tumor size ($9.2{\pm}3.9$ vs $6.1{\pm}3.6cm$, P=0.002) and the proximal resected margin ($2.1{\pm}2.0$ vs $3.6{\pm}2.1cm$ P=0.004). There was no significant difference in most of the peri- and post-operative courses such as the time to first flatus, the time to starting a solid diet and the length of the hospital stay, except for a longer operating time (289.0 vs. 361.3 minutes, P<0.001) in the LATG group. The complication rate was higher in the LATG group (13.8%) than that in the OTG group (5.7%). The mean overall survival and disease free survival times were 32 and 31 months, and 24 and 28 months, respectively, with an average 18.8 months follow-up duration. The main recurrent sites were peritoneum and lymph node in both groups. Conclusion: The early results of the current study suggest that LATG for AGC is technically feasible and it does not show any inferiorities of the postoperative outcomes as compared to those of conventional open total gastrectomy.

Purpose: To find the effects of semi-Fowler's position on the post-operative recovery for patients with laparoscopic abdominal surgery in recovery room. Method: The research was performed by nonequivalent control group non-synchronized quasi-experimental design. The subjects are forty patients who had laparoscopic abdominal surgery in a hospital from Aug. thru Nov. of 2003. Post-recovery scores and $O_2$saturation degree were measured. The experimental group was place in semi fowler's position while the control group was placed in supine position. The homogeneity between the control group and experimental group was analyzed using the Chi-square, and the hypothesis were tested using t-test. Result: 1. The patients in the experimental group placed in semi fowler's position showed significant higher post-recovery scores than those in the control group who were in a supine position. 2. The patients in the experimental group who were in semi Fowler's position showed no significant higher $O_2$ saturation degree than those in the control group who were in supine position. Conclusion: Based on the results described above, it is considered that the semi-Fowler's position might be effective in enhancing the post-operative recovery score of the patients with laparoscopic abdominal surgery in recovery room.

Purpose: The purpose of this study was to compare the recovery outcomes between a normal weight group (BMI<25) and an overweight group ($$BMI{\geq_-}25$$), who received laparoscopic surgery for rectal cancer, to provide information for effective decision making. Methods: Data from 76 patients who received laparoscopic surgery for rectal cancer in a university hospital were reviewed retrospectively from September 2004 to March 2007. Collected data were analyzed using Win SPSS 12.0. The recovery outcomes related to the operation were the length of the operation, the amount of bleeding during the operation, the length of stay in the recovery room, first bowel movement, the length of hospital stay, and complications. Results: There was no statistical difference between the two groups with regard to the recovery outcomes. Conclusion: From the above results, nursing information can be offered to help make effective decisions before the operation for overweight patients with rectal cancer who prefer laparoscopic surgery.

Purpose: Laparoscopy-assisted distal gastrectomy (LADG) is gaining wider acceptance for the treatment of early gastric cancer. However, firm evidence supporting the long-term outcome after LADG for gastric cancer is unknown. This study compared long-term quality of life after LADG versus an open distal gastrectomy (ODG) for early gastric cancer. Methods: This study included 29 patients who underwent LADG and 57 patients who underwent ODG for the treatment of stage I gastric cancer. Quality of life was evaluated based on the Korean version of EORTC QLQ-C30 (version 3.0) and EORTC QLQ-STO22 one year after surgery. All patients underwent a Billroth II gastrectomy for stage I gastric cancer between January 2003 and December 2004. Results: A total of 86 (58%) out of 154 patients responded to the questionnaire. Demographic features showed no difference between the two groups of patients for age, sex, depth of invasion, lymph node metastasis except for tumor size and the number of retrieved lymph nodes. The mean score for global health status was not statistically different (LADG, $60.3{\pm}20.4$ vs ODG, $57{\pm}20.6$; P=0.413). The total score of 21 items related to stomach cancer (EORTC QLQ-STO22) also was not statistically different (LADG, $68.9{\pm}64.9$ vs ODG, $94.5{\pm}97.3$; P=0.340). Conclusion: Based on the results of the Korean version of EORTC QLQ-C 30 (version 3.0) and EORTC. QLQ-STO22, LADG does not seem to have any long-term benefit over ODG on 'quality of life'.

A peritoneal loose body is reported to develop because of torsion and separation of the epiploic appendages. The condition is usually symptomless and may be incidentally during abdominal surgery or autopsy. It usually occurs in middle-aged and elderly adults and is very rare in children. In this paper, we report a case of a peritoneal loose body in the pelvic cavity of a 10-year old-girl who presented with urinary frequency and left lower abdominal discomfort. A second plain X-ray film of the abdomen, obtained before surgery, in a different view than the first, revealed that the calcified mass had migrated to a lower position. The mass was laparoscopically resected, and histological examination revealed it to be a fibrotic nodule with central liquefaction and calcification.

Laparoscopic surgery is a well-established alternative to open surgery across disciplines. However, in veterinary medicine, laparoscopic surgery in dogs was rarely reported because of small abdominal size for multiple ports insertion. The concept of single-incision laparoscopic surgery (SILS) is to perform the entire laparoscopic operation through a single incision rather than conventional multiple small skin incisions. Indirect evidence of potential benefits of SILS, decreases operative morbidity related to reduction in port size, already exists. Therefore, this study was performed to evaluate the safety and feasibility of the modified form of SILS using flexible endoscope in Cholecystectomy before clinical adoption. A 2 cm single periumbilical incision was performed, and flexible endoscope was introduced into the abdominal cavity. A laparoscopic grasper was inserted into the abdominal cavity for the traction of gall bladder. Cystic duct and artery were ligated by 5 mm Hem-o-lok$^{(R)}$. Then, gall bladder was dissected and resected from the liver with 5 mm Autonomy Laparo-Angle Maryland dissector and endoscopic needle knife. Resected gall bladder was wrapped by using specimen pouch and was retrieved through abdominal incision from the cavity. All three gall bladders were successfully removed. Hematological changes were not observed during examination periods. No leakage sign was identified at necropsy. The flexible endoscope, as distinct from conventional rigid laparoscope, allows the visualization from various angles and the wide range of motion, result in less crowding.

This study was performed to determine the estrous cycles by macroscopic observation of the ovarian changes using the laparoscopy and to make use of these results for embryo transfer in Korean black goat (Copra hircus aegagrus). Laparoscopic examinations of the ovaries were performed from 2 days after $CIDR^(R)$ removal to 22 days after ovulation. The serial morphological changes of follicles and corpus luteum (CL) were observed. CL was classified corpus hemorrhagicum(CH), corpus luteum (CL) and corpus albicans (CA) by its maturation and regression. On the day before ovulation (Day 0), Graafian follicles (GF) were found on one or both ovaries. On the day (Day 1) and $2^{nd}$day (Day 2) of ovulation, and ovulation depression (OD) and an early stage corpus hemorrhagicum $(CH_1)$ were observed at the site of GF, respectively. On Days 3 to 4, more developed and enlarged corpus hemorrhagicum $(CH_2\;and\;CH_3)$ arised from the ovulation of the GF with well vascularization. On Days 5 to 6, it was identified that mature corpus luteum $(CL_3)$ was grown on the ovary, and fully developed CL with adjacent follicles were occupied most part of the ovary on Days 17 and 18. Then the size of CL was diminished, and completely luteal regression $(CL_1\;or\;CA)$ with new large follicle was identified on Days 20 and 22. From these results, the 4 stages of the estrous cycle in Korean black goats were 1) estrus (Day 0) for 1 day, 2) metestrus $(Day\;1{\sim}4)$ for 4 days (stage of CH development), 3) diestrus $(Day\;5{\sim}16/17)$ for 12 or 13 days (luteal stage), and 4) proestrus $(Day\;17/18{\sim}20/22)$ for 4 or 5 days (stage of luteal regression and follicular growing). Laparoscopy for observation of ovarian changes was invasive than laparotomy. Additionally, it had advantages of reduced adhesion and quick operation time. It was considered that laparoscopic examination of ovarian changes will be useful for embryo transfer in the Korean black goats.

Minimally Invasive Surgery (MIS) is surgery of the chest, abdomen, spine and pelvis, done with the aid of a viewing scope, and specially designed instruments. Benefits of minimally invasive surgery are less pain, less need for post-surgical pain medication, less scarring and less likelihood for incisional complications. Since the late 1980's, minimally invasive surgery has gained widespread acceptance because of the such advantages. However there are significant disadvantages which have, to date, limited the applications for these promising techniques. The reasons are limited degree-of-freedom, reduced dexterity and the lack of tactile feeling. To overcome such disadvantages many researchers have endeavored to develop robotic systems. Even though some robot aided systems achieved success and commercialized, there still remain many thing to be improved. In this paper, the robotic system which can mimic whole motions of a human arm by adding additional DOF is presented. The suggested design is expected to provide surgeons with improved dexterity during minimally invasive surgery.
