Usually in the subtotal gastrectomy, the left and the right gastric arteries, as well as the left and the right gastroepiploic arteries are ligated. Thus, to avoid a blue stomach surgeons preserve the spleen and the short gastric arteries. When a radical subtotal gastrectomy with splenectomy is performed, meticulous caution is necessary; otherwise, the subtotal gastrectomy might have to be changed to a total gastrectomy to prevent a blue stomach. We report the case of a 67-year-old woman who had distal stomach cancer with a splenic solitary mass, for which splenic meatastasis could be excluded. We planned and performed a laparoscopy-assisted radical subtotal gastrectomy with splenectomy as the diagnostic and therapeutic option. In this case, to avoid a remnant stomach infarction or total gastrectomy we saved the left gastric artery and vein with clearing perivascular soft tissue, lymphatics, and lymph nodes. Thus the radical therapeutic goal was reached, and serious complications were avoided.

The prevalence of gastroesophageal reflux disease(GERD) has been increased recently in Korea. Most patients who have GERD are well treated by medication. But patients who have suboptimal disease control under medical therapy are needed further treatment. Nowadays minimally invasive surgery using laparoscopy and thoracoscopy has become popular in the operation of GERD although antireflux surgery is vary. Antireflux surgery is a well-documented, effective therapeutic alternative to control GERD.

An elective laparoscopic ovariectomy on a healthy dog revealed a cystic structure in the left ovary. The surgical procedure was successful. Histopathological examination showed the presence of a teratoma adjacent to the ovary. To the best of the authors' knowledge, this is the first reported case of an ovarian teratoma removed by laparoscopic ovariectomy in a dog by using a multiport laparoscopic ovariectomy technique.

Totally robotic esophagectomy is performed using a robotic technique without additional thoracoscopy or laparoscopy. However, most robotic esophagectomies are currently performed in a hybrid form combining robotic and other endoscopic techniques. Laparoscopic stomach mobilization and thoracoscopic esophagogastric anastomosis are commonly used methods in robotic esophagectomy. In this paper, totally robotic esophagectomy without thoracoscopic or laparoscopic assistance is presented.

Purpose: To evaluate the technical feasibility and oncologic safety, we assessed the short-term and long-term outcomes of laparoscopic resection of the small bowel gastrointestinal stromal tumors smaller than 5 cm by comparing those of open surgery by subgroup analysis based on tumor size. Materials and Methods: From November 1993 to January 2011, 41 laparoscopic resections were performed among the 95 patients who underwent resection of small intestine ${\leq}10$ cm in diameter. The clinicopathologic features, perioperative outcomes, recurrences and survival of these patients were reviewed. Results: The postoperative morbidity rates were comparable between the 2 groups. Laparoscopic surgery group showed significantly shorter operative time (P=0.004) and duration of postoperative hospital stay (P<0.001) than open surgery group and it was more apparent in the smaller tumor size group. There were no difference in 5-year survival for the laparoscopic surgery versus open surgery groups (P=0.163), and in 5-year recurrence-free survival (P=0.262). The subgroup analysis by 5 cm in tumor size also shows no remarkable differences in 5-year survival and recurrence-free survival. Conclusions: Laparoscopic resection for small bowel gastrointestinal stromal tumors of size less than 10 cm has favorable short-term postoperative outcomes, while achieving comparable oncologic results compared with open surgery. Thus, laparoscopic approach can be recommended as a treatment modality for patients with small bowel gastrointestinal stromal tumors less than 10 cm in diameter.

Purpose: Laparoscopic gastrectomy is a widely accepted surgical technique. Recently, robotic gastrectomy has been developed, as an alternative minimally invasive surgical technique. This study aimed to evaluate the question of whether robotic gastrectomy is feasible and safe for the treatment of gastric cancer, due to its learning curve. Materials and Methods: We retrospectively reviewed the prospectively collected data of 100 consecutive robotic gastrectomy patients, from November 2008 to March 2011, and compared them to 282 conventional laparoscopy patients during the same period. The robotic gastrectomy patients were divided into 20 initial cases; and all subsequent cases; and we compared the clinicopathological features, operating times, and surgical outcomes between the three groups. Results: The initial 20 robotic gastrectomy cases were defined as the initial group, due to the learning curve. The initial group had a longer average operating time ($242.25{\pm}74.54$ minutes vs. $192.56{\pm}39.56$ minutes, P>0.001), and hospital stay ($14.40{\pm}24.93$ days vs. $8.66{\pm}5.39$ days, P=0.001) than the experienced group. The length of hospital stay was no different between the experienced group, and the laproscopic gastrectomy group ($8.66{\pm}5.39$ days vs. $8.11{\pm}4.10$ days, P=0.001). The average blood loss was significantly less for the robotic gastrectomy groups, than for the laparoscopic gastrectomy group ($93.25{\pm}84.59$ ml vs. $173.45{\pm}145.19$ ml, P<0.001), but the complication rates were no different. Conclusions: Our study shows that robotic gastrectomy is a safe and feasible procedure, especially after the 20 initial cases, and provides a satisfactory postoperative outcome.

We analyzed our experience with orchidopexy for undescended testicle performed during recent 10 years in order to evaluate our results and to determine the most effective treatment of undecended testes. Between 1988 and 1997, we treated 420 undescended tested (314 palpable and 106 nonpalpable) in 356 boys. Medical records were reviewed with respect to age at presentation, the surgical approach, testicular location, testicular volume and the final outcome. The average patient age at presentation was 4.1 years with 40.2 % presenting before age 2 years. Of 106 nonpalpable testes, 23 testes were intra-abdominal, 32 were preperitoneal and 51 were absent. During the first 5 years, we performed orchidopexy through 31 inguinal and 13 midline transabdominal incisions for 44 paitents with nonpalpable testes. In the next 5 years, all 47 patients with nonpalpable were treated through inguinal incisions. For the nonpalpable testes, the inguinal approach with or without intraperitoneal extension was successful in defining the location of testes and blind-ending vessels in all patients. Laparoscopy did not help to avoid surgical exploration in all our patients with nonpalpable tests. Of 339 inguinal and midline tranabdominal orchidopexies without spermatic vessels ligations, 324 testes were placed in the scrotum, 4 in the upper scrotum and 3 in the inguinal area. Eight testes underwent atrophy. Of 13 Fowler-Stephens orchidopexies, 7 were placed in the scrotum and 6 became atrophied. Testicular growths were noticed in most patients who underwent orchidopexies and the colume of pexed testes became as large as the contralateral normal testes by the mean duration of 43.3 months postoperatively. In conclusion, orchidopexies were successful in most cases of cryptochidism in terms of testicular position and growth. However, there were more testicular atrophies in cases where spermatic vessels were ligated. In cases of nonpalpable undescended testes, the inguinal approach with or without intraperitoneal extesion would be recommended.

Recently, production of transgenic animal by nuclear transfer has been known as a useful method. The production of cloned offspring derived from nuclear transfer depends upon a variety of factors such as species, donor cells type and cell cycle, and source of recipient ova. Therefore, we attempted a different transgenic methods using follicular granulosa cells (GCs). In general, ovulated GCs undergoes lutenization and transformation in vitro which might defective effects on developmental potential. In order to avoid the GCs transformation in vitro culture system, we introduced a direct injection of retrovirus into the follicles and then collected them mechanically from ovaries of 6-8 week-old ICR mice. Retrovirus vector constructed with pLN $\beta$ EGFP was injected into the follicles. The follicles are cultured in $\alpha$ -MEM supplemented with human FSH, LH and ITS in Costar Transwell dish for 4 days. Survival rate of virus injected follicles was 52.1% (12/23) and expression rate of EGPP gene was 33.3% (4/12). In this study, we found GCs performed transgenesis in our culture system. In addition, the GCs in follicle may be developed in vivo like environment rather than in vitro environment. Thus, the use of GCs as donor cells may be useful in the nuclear transfer for cloning of genetic modification. Therefore, these results suggest that follicular GCs can be transfected by viral vector during folliculogenesis in vitro.
