Gastric cancer with gastric outlet obstruction has a high incidence of direct invasion into neighboring organs, with a low resection rate and a poor prognosis. Traditionally, open gastrojejunostomy has been the standard palliative treatment in these patients. Recently, endoscopic self-expanding metal stents have been used increasingly for the palliative treatment of malignant gastric outlet obstruction, but the choice of modality to treat the obstruction caused by gastric cancer is still controversial. Many studies have shown that endoscopic stenting is less invasive and offers not only a shorter time to oral intake and length of hospital stay, but also less frequent complications compared to open gastrojejunostomy. However, recurrent obstruction by tumor overgrowth and ingrowth occur more frequently and re-intervention for recurrent obstructive symptoms are more frequently performed after stent placement than after gastrojejunostomy. Thus, stent placement may be associated with more favorable results in patients with a relatively short life expectancy, while gastrojejunostomy is preferable in patients with a more prolonged prognosis. Also, open surgery affords a greater chance for curative surgery. However, most underlying diseases analyzed in previous studies were pancreaticobiliary malignancies, and there have been few prospective studies specific for patients with gastric cancer. Additional randomized controlled trials with larger sample sizes are expected to decide the treatment modality for unresectable gastric cancer with gastric outlet obstruction.

Purpose: Intracorporeal anastomosis during laparoscopic gastrectomy is becoming increasingly prevalent. However, selection of the anastomosis method after laparoscopic distal gastrectomy is equivocal because of a lack of technical feasibility and safety. We compared intracorporeal gastroduodenostomy with gastrojejunostomy using linear staplers to evaluate the technical feasibility and safety of intracorporeal anastomoses as well as its' minimally invasiveness. Materials and Methods: Retrospective analyses of a prospectively collected database for gastric cancer revealed 47 gastric cancer patients who underwent laparoscopic distal gastrectomy with either intracorporeal gastroduodenostomy or gastrojejunostomy from March 2011 to June 2011. Perioperative outcomes such as operation time, postoperative complication, and hospital stay were compared according to the type of anastomosis. Postoperative inflammatory response was also compared between the two groups using white blood cell count and high sensitivity C-reactive protein. Results: Among the 47 patients, 26 patients received gastroduodenostomy, whereas 21 patients received gastrojejunostomy without open conversion or additional mini-laparotomy incision. There was no difference in mean operation time, blood loss, and length of postoperative hospital stays. There was no statistically significant difference in postoperative complication or mortality between two groups. However, significantly more staplers were used for gastroduodenostomy than for gastrojejunostomy (n=6) than for gastroduodenostomy and (n=5). Conclusions: Intracorporeal anastomosis during laparoscopic gastrectomy using linear stapler, either gastroduodenostomy or gastrojejunostomy, shows comparable and acceptable early postoperative outcomes and are safe and feasible. Therefore, surgeons may choose either anastomosis method as long as oncological safety is guaranteed.

Purpose: In gastric cancer patients with gastric outlet obstruction, there are several complications such as malnutrition and vomiting. Palliative enteral stenting is a less invasive procedure as compared with a gastrojejunostomy. The aim of this study was to determine whether there was a significant difference between patients that undergone palliative enteral slanting and patients that had received a bypass gastrojejunostomy. Materials and Methods: One hundred patients underwent palliative entering stenting and 3f patients were subjected to a surgical bypass gastrojejunostomy. We reviewed the medical records of the patients with gastric outlet obstruction secondary to far advanced gastric cancer that were diagnosed using a gastrofibroscope, UGI and abdominal CT, and were admitted to our institution between January 2000 and August 2006. The outcome of stent placement for gastric outlet obstruction was compared with palliative gastrojejunostomy during the same period. We excluded patients with recurrent gastric cancer and double cancer from this study. Results: There were significant differences between the group of patients that underwent slanting and the group of patients that received a gastrojejunostomy regarding the age of patients ($67{\pm}12$ vs. $57{\pm}9$, P<0.001) but not between the sex of the patients (M : F, 2 : 1 vs. 2 :1, P=0.637). The most common complication of stenting was tumor ingrowth (16/100, 16%) and the second most common complication was stent migration (14/100). Failure of the procedure occurred in only three patients. Twenty-three patients underwent re-slanting and one patient required open conversion with a gastrojejunostomy. The median time to the first meal was $4{\pm}2$ days in the stent group of patients and $6{\pm}2$ days in the gastrojejunostomy group of patients (P=0.001). The median postoperative hospital stays were 9 days in the stent group of patients and 15 days in the gastrojejunostomy group of patients (P=0.003). The mean survival periods were 11 months in the stent group of patients and 10 months in the gastrojejunostomy group of patients (P=0.937). Conclusion: There were no significant differences In the mean survival rates. An earlier first meal and a shorter hospitalization stay were found in the slanting group of patients compared to the bypass gastrojejunostomy group of patients. However, re-slanting was a concern due to tumor ingrowth and stent migration.

Laparoscopic gastrectomy for cancer has some significant postoperative benefits over open surgery with similar oncologic outcomes. This procedure is more popular in the Far East countries where obesity is not a serious public health problem. In the Western countries, laparoscopic gastrectomy for cancer is not a common procedure, yet obesity is more common. Herein, we aimed to demonstrate the feasibility of laparoscopic gastrectomy for advanced gastric cancer in a morbidly obese patient. Additionally, we used natural orifice specimen extraction as an option to decrease wound-related complications, which are more prevalent in morbidly obese patients. In this case, we performed a fully laparoscopic subtotal gastrectomy with lymph node dissection and Roux-en-Y gastrojejunostomy with the specimen extracted through the vagina. To the best of our knowledge, this was the first report of a natural orifice surgery in a morbidly obese patient with gastric cancer.

Purpose: Mechanical stapler is regarded as a good alternative to the hand sewing technique, when used in gastric reconstruction. The circular stapling method has been widely applied to gastrectomy (open orlaparoscopic), for gastric cancer. We illustrated and compared the hand-sutured method to the circular stapling method, for Billroth-II, in patients who underwent laparoscopy assisted distal gastrectomy for gastric cancer. Materials and Methods: Between April 2009 and May 2011, 60 patients who underwent laparoscopy assisted distal gastrectomy, with Billroth-II, were enrolled. Hand-sutured Billroth-II was performed in 40 patients (manual group) and circular stapler Billroth-II was performed in 20 patients (stapler group). Clinicopathological features and post-operative outcomes were evaluated and compared between the two groups. Results: Nosignificant differences were observed in clinicopathologic parameters and post-operative outcomes, except in the operation times. Operation times and anastomosis times were significantly shorter in the stapler group (P=0.004 and P<0.001). Conclusions: Compared to the hand-sutured method, the circular stapling method can be applied safely and more efficiently, when performing Billroth-II anastomosis, after laparoscopy assisted distal gastrectomy in patients with gastric cancer.

Purpose: Laparoscopic gastrectomy has been common treatment modality for gastric cancer. But, most surgeons tend to perform laparoscopy-assisted distal gastrectomy using epigastric incision. Delta-shaped anastomosis is known as intracorporeal gastroduodenostomy, but it is technically difficult and needed many staplers. So we tried to find simple and economical method, here we report on the results of liner-shaped gastroduodenostomy in totally laparoscopic distal gastrectomy. Materials and Methods: We retrospectively reviewed the medical records of 25 patients who underwent totally laparoscopic distal gastrectomy using liner-shaped anastomosis at School of Medicine, Ajou University between January to October 2009. The indication was early gastric cancer as diagnosed by preoperative workup, the anastomoses were performed by using laparoscopic linear stapler. Results: There were 12 female and 13 male patients with a mean age of $55.6{\pm}11.2$. The following procedures were performed 14 laparoscopic gastrectomies, 11 robotic gastrectomies. The mean operation time was $179.5{\pm}27.4$ minutes, the mean anastomotic time was $17.5{\pm}3.4$ minutes. The mean number of stapler cartridges was $5.6{\pm}0.8$. Postoperative complication occurred in one patient, anastomotic stenosis, and the patient required reoperation to gastrojejunostomy. The mean length of postoperative hospital stay was $6.7{\pm}1.0$ days except the complication case, and there was no case of conversion to open procedure and postoperative mortality. Conclusions: Linear-shaped gastroduodenostomy in totally laparoscopic distal gastrectomy is technically simple and feasible method.
