Purpose: The intracorporeal reconstruction after laparoscopic gastrectomy can minimize postoperative pain, and give better cosmetic effect, while it may have technical difficulties and require the learning curve. This study aimed to analyze the surgical outcome of intracorporeal reconstruction according to the surgeon's experience comparing with extracorporeal procedure. Materials and Methods: From January 2009 to September 2011, intracorporeal reconstruction in laparoscopic surgery for gastric cancer was performed for 71 patients (Intra group). During same period, 231 patients underwent laparoscopy-assisted gastrectomy (Extra group). These patients were classified into initial (1st to 20th case of intra group), intermediate (21th to 46th case), and experienced (after 47th case) phases. Results: Intracorporeal procedures included 35 cases of Billroth-I, 30 Billroth-II and 6 Roux en Y reconstructions. In the initial phase, operation time (P=0.022) were significantly longer for the patients of intra group than them of extra group. Although the difference was not significant, the length of hospital stay was longer and complication rate was higher in the intra group. In intermediate and experienced phases, there was no difference between two groups in operation time and hospital stay. In these phases, complication rate was lower in the intra group than the extra group (3.9% versus 9.7%). The pain scale was significantly lower post operation day 5 in the intra group. Conclusions: Intracorporeal reconstruction after laparoscopic distal gastrectomy was feasible and safe, and the technique was stabilized after 20th case if the surgeon has sufficient experiences when we compared it with extracorporeal reconstruction.
Purpose: The number of laparoscopy assisted distal gastrectomies (LADG) is gradually increasing for the treatment of early gastric cancer (EGC) patients as a surgical modality for improving quality of life. However, there are few reports on laparoscopy-assisted total gastrectomy (LATG), mainly because this procedure is performed relatively infrequently, and the procedure is more complicated than LADG. This study was performed to evaluate the technical feasibility, safety, and surgical results of LATG with lymphadenectomy through a review of our experience. Materials and Methods: From July 2003 to June 2007, 77 LATG with Roux-en-Y esophagojejunostomy were performed for patients with a preoperative diagnosis of EGC. The clinicopathological features and surgical outcomes were analyzed. Results: There were 49 males and 28 females in the study with a mean age of 61 years (range $30{\sim}85$ years). The mean operation time was 210 minutes (range $100{\sim}400$ minutes) and the operation time was gradually decreased as the case numbers increased. There were 13 operative morbidities (16.9%) and no operative mortalities. The restoration of bowel motility was noted at 3.2 postoperative days; a soft diet was started at 4.4 postoperative days and the duration of hospital stay was 10 days. There were 20 mucosal lesions, 32 submucosal lesions, 15 proper muscle lesions, 7 subserosal lesions and 3 serosal lesions. A total of 20 patients were treated by D2 lymph node dissection, 55 patients were treated by D1+$\beta$ lymph node dissection, and two patients were treated by D1+$\alpha$ lymph node dissection. The mean number of retrieved lymph nodes was 42 (range $11{\sim}86$). Lymph node metastases were noted in 12 patients. Conclusion: This study indicated LATG could be applied safely and effectively for patients with EGC. However, a prospective study comparing laparoscopy-assisted versus open gastrectomy for short-term and long-term surgical outcome is needed.
This nationwide survey was conducted to evaluate the current status of clinical practice for gastric cancer patients in Korea. The Information Committee of the Korean Gastric Cancer Association (KGCA) sent questionnaires containing 45 items about the preoperative diagnosis, medical and surgical treatment, and postoperative follow-up for gastric cancer patients to all 298 KGCA members in 108 institutes. Response rates were $32.6\%$ (97/298) for individuals and $59.3\%$ (64/108) for institutes. Most university hospitals responded (response rate of university hospitals: $71.6\%$, 48/67). The preoperative staging work up was performed primarily by abdominal CT, followed by bone scans, abdominal ultrasound, endoscopic ultrasound, and so on. Gastric cancer patients with stages II, III, and IV usually received adjuvant chemotherapy after a curative operation. About half of the surgeons regarded 2 cm as a safe resection margin in early gastric cancer and 5 cm in advanced gastric cancer. More than half of surgeons usually performed a D2 lymph node dissection in early gastric cancer and D2+$\alpha$ lymph node dissection in advanced gastric cancer. About $20\%$ of surgeons performed less invasive surgery and/or function-preserving surgery, such as a pylorus-preserving gastrectomy, a laparoscopic wedge resection, or a laparoscopy-assisted distal gastrectomy.
Purpose: This study aimed to compare the surgical and oncological outcomes between totally laparoscopic pylorus-preserving gastrectomy (TLPPG) with intracorporeal anastomosis and laparoscopy-assisted pylorus-preserving gastrectomy (LAPPG) with extracorporeal anastomosis. Materials and Methods: A retrospective analysis was performed in 258 patients with cT1N0 gastric cancer who underwent laparoscopic pylorus-preserving gastrectomy using two different anastomosis methods: TLPPG with intracorporeal anastomosis (n=88) and LAPPG with extracorporeal anastomosis (n=170). The following variables were compared between the two groups to assess the postoperative surgical and oncological outcomes: proximal and distal margins, number of resected lymph nodes (LNs) in total and in LN station 6, operation time, postoperative hospital stay, and postoperative morbidity including delayed gastric emptying (DGE). Results: The average length of the proximal margin was similar between the TLPPG and LAPPG groups (2.35 vs. 2.73 cm, P=0.070). Although the distal margin was significantly shorter in the TLPPG group than in the LAPPG group (3.15 vs. 4.08 cm, P=0.001), no proximal or distal resection margin-positive cases were reported in either group. The average number of resected LN was similar in both groups (36.0 vs. 33.98, P=0.229; LN station 6, 5.72 vs. 5.33, P=0.399). The operation time was shorter in the TLPPG group than in the LAPPG (200.17 vs. 220.80 minutes, P=0.001). No significant differences were observed between the two groups in terms of postoperative hospital stay (9.38 vs. 10.10 days, P=0.426) and surgical complication rate (19.3% vs. 22.9%), including DGE (8.0% vs. 11.8%, P=0.343). Conclusions: The oncological safety and postoperative complications of TLPPG with intracorporeal anastomosis are similar to those of LAPPG with extracorporeal anastomosis.

Purpose: With advancements in laparoscopic surgery, there have been efforts to expand the indication for laparoscopic surgery up to advanced gastric cancer. However, scant data are available regarding the feasibility and advantages of laparoscopy-assisted distal gastrectomy (LADG) with standard radical D2 lymph node dissection. Materials and Methods: Twenty-two patients who were preoperatively diagnosed with cT1N0M0 gastric cancer underwent LADG with standard D2 lymphadenectomy between February and August 2007. They were compared with patients who underwent conventional open D2 lymphadenectomy with respect to clinicopathologic features, surgical outcomes, and postoperative course. Results: The mean operative time was significantly longer in the LADG group than in the open group ($160{\pm}25min$ vs. $135{\pm}21min$, P<0.001). However, surgical outcomes, such as surgical margin and number of retrieved lymph nodes ($25.7{\pm}11.1$ vs. $26.9{\pm}9.2$, P=ns) were comparable between the groups. The LADG group exhibited quicker postoperative recovery, and both groups exhibited similar postoperative morbidity and mortality. Conclusion: LADG with D2 lymphadenectomy is feasible and safe, with short-term surgical outcomes comparable to those seen in open D2 lymphadenectomy. Further prospective clinical investigation will be needed to better evaluate the advantages of LADG with D2 lymphadenectomy.

Purpose: There has been increased the number of early gastric cancer and laparoscopy-assisted gastrectomy (LAG), due to early detection through mass screening program. We started the LAG in April 2004 and performed 119 cases of gastric cancer in 2005, so we report a surgical outcome compared with that of open gastrectomy (OG). Materials and Methods: 119 patients underwent LAG in 2005, and for open group, 126 patiens of early gastric cancer were selected sequentially from January 2005 to March 2005. We compared clinicopathologic characteristics, postoperative courses and complications between two groups. Results: There was no significant difference between age, a length of hospital stay, distal resection margin and a number of retrived lymph nodes. The operation time was longer in LAG group (239.2 vs 123.3 mins, P<0.001) and a diet progression was faster in LAG group (first flatus: 3.05 vs 3.70 days, SOW: 2.86 vs 3.22 days, liquid diet: 3.87 vs 4.19 days, soft diet: 4.84 vs 5.26 days, P<0.001). But there was no difference statistically in postoperative discharge date (7.73 vs 8.25 days, P=0.229). The additional requirement of analgesic injection was less frequent in LAG group (2.97 vs 4.92 times, P<0.001). The harvested lymph nodes were similar in both groups (23.9 vs 23.1, P=0.563). A complication rate was lower in LAG group (4.9% vs 9.5%), but there was no statistical significance (P=0.179). There was no mortality in both groups and no conversion to open gastrectomy in the LAG group. Conclusion: LAG can be performed safely and accepted in view of curative procedure in treatment of early gastric cancer. But we need the follow up of long-term period to evaluate the survival rate and recurrence, and a prospective randomized controlled study should be done to establish that LAG will be a standard operation for early gastric cancer.
The Korean laparoscopic Gastrointestinal Surgery Study Group made a survey of laparoscopic gastric surgeries which were performed in Korea during 2004. Thirty-eight surgeons from 36 Institutions responded to the questionnaires. One thousand eighty-nine laparoscopic gastric operations were performed during 2004. The cumulative number from 1995 to 2004 was about 2,386. Seven hundred fifty-four operations for a gastric adenocarcinoma were performed during 2004 which is almost two times the number performed during 2003. Laparoscopic radical procedures, such as a laparoscopy-assisted distal gastrectomy or total gastrectomy (LADG and LATG) have increased rapidly since 2001 (55 cases in 2001, 150 cases in 2002, 364 cases in 2003 and 738 cases in 2004). Especially, laparoscopic total gastrectomies were explosively adopted last year (20 cases in 2003 and 112 cases in 2004). However, laparoscopic function-preserving gastrectomies, which included one laparoscopy-assisted pylorus-preserving gastrectomy and laparoscopy-assisted proximal gastrectomy, are rarely performed at this time. One hundred forty-two wedge resections for a gastric submucosal tumor were performed during 2004. Hand-assisted laparoscopic surgery (HALS) was performed in 39 cases in 2001, 55 in 2002, and 49 in 2003; however, only 5 such surgeries were performed during 2004. In 2003, laparoscopic bariatric surgery began, and during 2004, 49 operations were performed. In terms of indications of laparoscopic gastric surgery for adenocarcinoma, 19 surgeons performed a LADG only for a T1 lesion, and 7 surgeons extended their indications to T2N0 lesions. In the near future, laparoscopic procedures for gastric cancer will be widely adopted in Korea if the medical-insurance obstacle is overcome, and the long-term survival results are verified.

Purpose: The use of laparoscopic surgery for gastric disease has been gaining popularity. However, there has been the controversy over the indications and the standard techniques of laparoscopic gastric surgery in the early gastric cancer (EGC). The purposes of this study were to compare the clinical outcomes among a hand-assisted laparoscopic distal gastrectomy (HALDG), a laparoscopy-assisted distal gastrectomy (LADG), and an open distal gastrectomy (ODG) and to discuss the role of these procedures in the treatment of EGC. Materials and Methods: Between August 2001 and July 2004, laparoscopic surgery was performed in our institution on 25 patients, LADG (n=7) and HALDG (n=18) with EGC. Analysis was performed on clinical data such as the operative time, the hospital stay, the start of oral intake, and the number of harvested lymph nodes. Patients were categorized into early and late groups by using the date of surgery and were also grouped by surgical procedure. To evaluate the feasibility and efficacy of laparoscopic surgery for EGC, we compared the clinical data with those for ODGs performed during the same period. Results: There was no difference in the number of harvested lymph nodes between the laparoscopic group and the open group, but the operation time in the laparoscopic group was longer than that in the open group (P<0.05). Also, no significant differences in other clinical data were found between the two groups. Comparing the early and the late periods of the series, the number of harvested lymph nodes for a HALDS increased from $22.31\pm4.29\;to\;29.40\pm3.21$ (P<0.05). Conclusion: Our early experience with laparoscopic gastric surgery shows that a wide range of possibilities exist for applying laparoscopic gastric surgery to selected gastric cancer patients. However, the surgical procedure should be standardized, and the outcomes of laparoscopic surgery, in comparison to those of open surgery, need to be confirmed based on a large randomized study.

Purpose: Laparoscopic surgery for gastric cancer was introduced in the past decade because it was considered less invasive than open surgery, and this results in less postoperative pain, faster recovery and an improved quality of life. Several studies have demonstrated the safety and feasibility of this procedure. We examined the outcome of performing laparoscopic surgery for gastric cancer over the last two year. Materials and Methods: From April 2004 to December 2006, 329 patients with gastric adenocarcinoma underwent a laparoscopy-assisted distal gastrectomy with lymph node dissection. The data was retrospectively reviewed in terms of the clinicopathologic findings, the perioperative outcomes and the complications. Results: The total patient group was comprised 196 men (59.6%) and 133 women (40.4%). The mean BMI was 23.6 and the mean tumor size was 2.7 cm. The mean number of harvested lymph node was 22.7, and this was 18.6 before 30 cases and 23.1 after 30 cases, and the difference was significant (P=0.02). The mean operation time was 180.9 min, and this was than 287.9 min before 30 cases and 170.2 min after 30 cases. After 30 cases, there was a significant improvement of the operation time (P<0.01). The mean incision length after 30 cases was shorter than that before 30 cases (P<0.01). Postoperative complications occurred in 24 (7.3%) of 329 patients and there was no conversion to open surgery. Conclusion: Even though the LADG was accompanied by a difficult learning curve, we successfully performed 329 LADG procedures over the past 2 years and we believe that LADG is a safe, feasible operation for treating most early gastric cancers (EGC).

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'.
