This meta-analysis was performed to evaluate and compare the outcomes of robotic gastrectomy (RG) and laparoscopic gastrectomy (LG) for treating gastric cancer. A systematic literature search was carried out using the PubMed database, Web of Knowledge, and the Cochrane Library database to obtain comparative studies assessing the safety and efficiency between RG and LG in May, 2013. Data of interest were analyzed by using of Review Manager version 5.2 software (Cochrane Collaboration). A fixed effects model or random effects model was applied according to heterogeneity. Seven papers reporting results that compared robotic gastrectomy with laparoscopic gastrectomy for gastric cancer were selected for this meta-analysis. Our metaanalysis included 2,235 patients with gastric cancer, of which 1,473 had undergone laparoscopic gastrectomy, and 762 had received robotic gastrectomy. Compared with laparoscopic gastrectomy, robotic gastrectomy was associated with longer operative time but less blood loss. There were no significant difference in terms of hospital stay, total postoperative complication rate, proximal margin, distal margin, numbers of harvested lymph nodes and mortality rate between robotic gastrectomy and laparoscopic gastrectomy. Our meta-analysis showed that robotic gastrectomy is a safe technique for treating gastric cancer that compares favorably with laparoscopic gastrectomy in short term outcomes. However, the long term outcomes between the two techniques need to be further examined.

A gastroduodenostomy is the most physiological reconstruction after a distal gastrectomy. However, a gastroduodenostomy with either sutures or staples has many complications. These include bleeding, leakage and stenosis. A sutureless gastroduodenostomy with a biofragmentable anastomosis ring (BAR) in was used adenocarcinoma patients to prevent these complications from 1999. A BAR is composed of polyglycolic acid and Barium sulfate to allow for X-ray visualization. Hardy in first introduced the BAR in 1985. Since then, it has been used in an anastomosis of the colon or small bowel surgery but its use in a gastroduodenostomy is the first trial in the world. A 70 year male patient, old who received a subtotal gastrectomy (Billroth I), underwent a A sutureless gastroduodenostomy with a BAR. The gastroduodenostomy with the BAR was watertight and maintained the initial burst strength in the gastrografin X-ray study performed at the postoperative 1 week. The BAR began to fragment 3 weeks after the operation and disappeared from the digestive tract completely. The diameter of the anastomosis site was sufficient for passed foods. No other secondary changes from remained foreign bodies were found in the endoscopic examination. In a second operation to treat a primary hepatoma, there was no adhesive changes around the gastroduodenostomy site. In conclusion, a sutureless gastroduodenostomy with BAR is a safe, easy and efficient reconstructive method after a distal gastrectomy.

목적: 위암이 국소적으로 진행하여 췌장과 비장으로 직접 침윤이 발생되었을 췌-비장 절제를 시행하는 것에는 반대 의견이 없지만, 췌-비장의 보존이 가능함에도 불구하고, 비장혈관이나 비문부 림프절의 완전 절제를 위해서 췌-비장 절제가 시행되는 것은 논란의 여지가 많다 저자들은 위 중-상부의 진행암으로 위 전절제술과 함께 원위부 췌-비장 절제가 시행되었던 환자들의 수술 결과 분석을 통하여 불필요한 합병절제를 피할 수 있는 방법을 찾고자 하였다. 대상 및 방법: 1990년부터 2001년까지 가톨릭대학교 의과대학 외과학교실에서 위 전절제술과 동반되어 원위부 췌-비장 절제가 시행된 118명의 환자 중, 병리 조직학적으로 암의 췌장 침윤이 없었던 90예(I군)와 침윤이 확인된 28예(II군)의 임상병리학적 특성, 이환율과 사망률 및 생존율 등을 후향적으로 분석하였다. 결과: 전체 118예 중 췌장 침윤이 확인된 pT4는 28예(23.7%)였고, 침윤이 없었던 pT3과 pT2가 각각 65예(55.1%) 와 20예(16.9%)였으며, pT1도 5예(4.3%)였다. 병기는 28예의 pT4 중에서 림프절 전이가 있어 IV기인 경우가 25예(89.3%)였고, 림프절 전이가 없는 IIIa기는 3예(10.7%)에 불과하였다. 또한 I군은 la (pT1N0)기 4예, Ib (pT2N0)기 7예였고, II기는 pT2N1 8예, pT3N0 12예, pT1N2 1예였으며, III기는 IIIa 15예, IIIb 17예, IV기는 26예였다. 두 군의 임상병리학적 특성 중 병기, 절제연 및 근치도에서 유의한 차이를 보였고, 생존에 영향을 미치는 인자들의 단변량 분석에서는 병기, 위벽 침윤, 췌장 침윤, 림프절전이, 비장혈관과 비문부 림프절 전이, 전이 림프절 비율, 근치도, 간 및 복막 전이 등에서 유의한 차이를 보였으며, 이 중 병기와 전이 림프절 비율 및 근치도가 예후에 영향을 미치는 독립적 예후인자로 나타났다. 5년 생존율은 I군이 36.2%, II군이 13.9%였고, 술 후 합병증으로 췌장 루 6예(5.1%), 복강 내 농양 5예(4.2%), 출혈 5예(4.2%)로 수술로 인한 전체 이환율은 22.1%였으며, 사망률은 6.8% (8예)였다. 결론: 진행성 상부 위암으로 위 전 절제술을 시행할 때 원위부 췌-비장 절제는 이환율이 비교적 높은 술식이기 때문에 간이나 복막전이가 없는 상태에서 위암의 병기가 높고, 절제연이 불충분하며, 근치적 절제가 불가능하다고 판단될 때에만 선택적으로 시행되는 것이 좋다고 생각한다.

Purpose: Laparoscopy-assisted gastrectomy (LAG) has become a technically feasible and safe procedure for early gastric cancer treatment. LAG is being increasingly performed in many centers; however, there have been few reports regarding LAG at low-volume centers. The aim of this study was to report our early experience with LAG in patients with gastric cancer at a low-volume center. Materials and Methods: The clinicopathologic data and surgical outcomes of 39 patients who underwent LAG for gastric cancer between April 2007 and March 2010 were retrospectively reviewed. Results: The mean age was 68.3 years. Thirty-one patients had medical co-morbidities. The mean patient ASA score was 2.0. Among the 39 patients, 4 patients underwent total gastrectomy and 35 patients underwent distal gastrectomy. The mean blood loss was 145.4 ml and the mean operative time was 259.4 minutes. The mean time-to-first flatus, first oral intake, and the postoperative hospital stay was 2.8, 3.1, and 9.3 days, respectively. The 30-day mortality rate was 0%. Postoperative complications developed in 9 patients, as follows: anastomotic leakage, 1; wound infection, 1; gastric stasis, 2; postoperative ileus, 1; pneumonia, 1; cerebral infarction, 1; chronic renal failure, 1; and postoperative psychosis, 1. Conclusions: LAG is technically feasible and can be performed safely at a low-volume center, but an experienced surgical team and careful patient selection are necessary. Furthermore, for early mastery of the learning curve for LAG, surgeons need education and training in addition to an accumulation of cases.

Purpose: Gastric submucosal tumors (SMTs) located very close to the esophagogastric junction (EGJ) are a challenge for gastric surgeons. Therefore, this study reports on the experience of using endoscopic and laparoscopic full-thickness resection (ELFR) with laparoscopic two-layer suturing in such tumors. Materials and Methods: Six patients with gastric SMTs very close to the EGJ underwent ELFR with laparoscopic two-layer suturing at Kyungpook National University Medical Center. With the patient under general anesthesia, the lesser curvature and posterior aspect adjacent to the EGJ were meticulously dissected and visualized using a laparoscopic approach. A partially circumferential full-thickness incision at the distal margin of the tumor was then made using an endoscopic approach under laparoscopic guidance. The SMT was resected using laparoscopic ultrasonic shears, and the gastric wall was closed using two-layer suturing. Thereafter, the patency and any leakage were checked through endoscopy. Results: All the ELFR procedures with laparoscopic two-layer suturing were performed successfully without an open conversion. The mean operation time was $139.2{\pm}30.9$ minutes and the blood loss was too minimal to be measured. The tumors from four patients were leiomyomas, while the tumors from the other two patients were gastrointestinal stromal tumors with clear resection margins. All the patients started oral intake on the third postoperative day. There was no morbidity or mortality. The mean hospital stay was $7.7{\pm}0.8$ days. Conclusions: ELFR with laparoscopic two-layer suturing is a safe treatment option for patients with an SMT close to the EGJ, as major resection of the stomach is avoided.

Purpose: Electrogastrography is a method of measuring action potentials of the stomach. The purpose of this study was to investigate early postoperative changes in the electrogastrography and determine the correlation between electrogastrography and quality of life of patients with stomach cancer who underwent distal gastrectomy. Materials and Methods: This study analyzed 20 patients with stomach cancer who underwent electrogastrography and quality of life was measured 1, 12, and 24 weeks after the operation. Quality of life-C30 version 3.0 and quality of life-STO22, were used. Results: Fasting and postprandial mean dominant frequency at 1 week after the operation was 2.7 and 2.7 cycles per minute, and 2.8 and 2.7 cycles per minute at 12 weeks, 2.6 and 2.8 cycles per minute at 24 weeks. Fasting and postprandial mean dominant power at 1 week was 36.5 and 36.4 dB, 36.3 and 40.1 dB at 12 weeks and 40.9 and 42.3 dB at 24 weeks. The percentage of tachygastria was increased whereas the percentage of bradygradia was decreased during the postoperative periods (P<0.05). Global health, physical, emotional and social functioning scales were improved, but role and cognitive functioning were not changed. Pain, insomnia, diarrhea and financial difficulties were significantly improved according to the postoperative periods (P<0.05). The correlation between the STO22 and electrogastrography parameters was not significant (P>0.05). Conclusions: These may suggest that electrogastrography is a simple and noninvasive method and may be applicated for evaluating motility and autonomic functions of the remnant stomach.

Background: Esophageal cancer is one of the major health concerns in Southeast Asian countries, including Thailand. However, only a limited number of studies have been reported from this region. This study was designed to evaluate the prevalence, clinical characteristics and survival rate of esophageal cancer in Thailand. Materials and Methods: Clinical information, histological features and endoscopic findings were collected from a tertiary care center in central region of Thailand between September 2011- November 2014 and reviewed. Results: A total of 64 esophageal cancer patients including 58 men and 6 women with mean age of 62.6 years were enrolled. Common presenting symptoms were dysphagia (74%), dyspepsia (10%) and hematemesis (8%). Mean duration of symptoms prior to diagnosis was 72 days. Esophageal stenosis with contact bleeding was the most common endoscopic finding (55.6%). The location of cancer was found in proximal (16%), middle (50%) and distal (34%) esophagus. Squamous cell carcinoma was far more common histology than adenocarcinoma (84.2% vs 10.5%). However, esophageal adenocarcinoma was significantly more common than squamous cell carcinoma in distal area of esophagus (100% vs 22.9%; p=0.0001, OR=1.6, 95%CI=1.1-2.2). Esophageal cancer stages 3 and 4 accounted for 35.2% and 59.3% respectively. Overall 2-year survival rate was 20% and only 16% in metastatic patients. Conclusions: Most esophageal cancer patients in Thailand have squamous cell carcinoma and nearly all present at advanced stage with a grave prognosis. Screening of high risk individuals and early detection might be important keys to improve the survival rate and treatment outcome in Thailand.

Purpose: Perioperative chemotherapy improves survival outcomes in locally advanced (LA) gastric cancer. Materials and Methods: We retrospectively analyzed patients with LA gastric cancer who were offered perioperative chemotherapy consisting of epirubicin, oxaliplatin, and capecitabine (EOX) from May 2013 to December 2015 at Tata Memorial Hospital in Mumbai. Results: Among the 268 consecutive patients in our study, 260 patients (97.0%) completed neoadjuvant chemotherapy, 200 patients (74.6%) underwent D2 lymphadenectomy, and 178 patients (66.4%) completed adjuvant chemotherapy. The median follow-up period was 17 months. For the entire cohort, the median overall survival (OS), 3-year OS rate, median progression-free survival (PFS), and 3-year PFS rate were 37 months, 64.4%, 31 months, and 40%, respectively. PFS and OS were significantly inferior in patients who presented with features of obstruction than in those who did not (P=0.0001). There was no difference in survival with respect to tumor histology (well to moderately differentiated vs. poorly differentiated, signet ring vs. non-signet ring histology) or location (proximal vs. distal). Survival was prolonged in patients with an early pathological T stage and a pathological node-negative status. In a multivariate analysis, postoperative pathological nodal status and gastric outlet obstruction on presentation significantly correlated with survival. Conclusions: EOX chemotherapy with curative resection and D2 lymphadenectomy is a suggested alternative to the existing perioperative regimens. The acceptable postoperative complication rate and relatively high resections, chemotherapy completion, and survival rates obtained in this study require further evaluation and validation in a clinical trial.

Purpose: In the UICC staging system, stage IV contains not only those patients with distant metastasis but also patients with far advanced T and N status but without distant metastasis. We investigated the prognostic factors of stage IV gastric carcinoma patients without distant metastasis after curative resection. Materials and Methods: 190 stage IV gastric carcinoma patients without distant metastasis were reviewed after curative resection. Results: Male sex, distal third location, Borrmann type III, IV and histologically undifferentiated type were common. 5 year survival rate of the 190 patients was $22.2\%$. Depth of invasion and lymph node metastasis did not influence survival. The lymph node ratio (positive lymph node / retrieved lymph node) and combined resection affected survival by univariate and multivariate analysis. Conclusion: Combined resection and positive lymph node ratio were the independent prognostic factors in the patients with stage IV gastric carcinoma who underwent curative resection.
