Laparoscopic-assisted vs open transhiatal gastrectomy for Siewert type II adenocarcinoma of the esophagogastric junction: A retrospective cohort study. World J Gastrointest Surg 2022; 14:304-314. [PMID: 35664362 PMCID: PMC9131839 DOI: 10.4240/wjgs.v14.i4.304] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/07/2021] [Revised: 01/15/2022] [Accepted: 03/27/2022] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND The studies of laparoscopic-assisted transhiatal gastrectomy (LTG) in patients with Siewert type II adenocarcinoma of the esophagogastric junction (AEG) are scarce.
AIM To compare the surgical efficiency of LTG with the open transhiatal gastrectomy (OTG) for patients with Siewert type II AEG.
METHODS We retrospectively evaluated a total of 578 patients with Siewert type II AEG who have undergone LTG or OTG at the First Medical Center of the Chinese People’s Liberation Army General Hospital from January 2014 to December 2019. The short-term and long-term outcomes were compared between the LTG (n = 382) and OTG (n = 196) groups.
RESULTS Compared with the OTG group, the LTG group had a longer operative time but less blood loss, shorter length of abdominal incision and an increased number of harvested lymph nodes (P < 0.05). Patients in the LTG group were able to eat liquid food, ambulate, expel flatus and discharge sooner than the OTG group (P < 0.05). No significant differences were found in postoperative complications and R0 resection. The 3-year overall survival and disease-free survival performed better in the LTG group compared with that in the OTG group (88.2% vs 79.2%, P = 0.011; 79.7% vs 73.0%, P = 0.002, respectively). In the stratified analysis, both overall survival and disease-free survival were better in the LTG group than those in the OTG group for stage II/III patients (P < 0.05) but not for stage I patients.
CONCLUSION For patients with Siewert type II AEG, LTG is associated with better short-term outcomes and similar oncology safety. In addition, patients with advanced stage AEG may benefit more from LTG in the long-term outcomes.

Abstract
BACKGROUND The purpose of the study was to investigate the proliferation and migration capability of human gastrointestinal stromal tumor line GIST-T1 after exposure to different pressures and times of CO2 pneumoperitoneum. METHODS We established simulated CO2 pneumoperitoneum environment in vitro and divided the human GIST cell GIST-T1 into open control group, 8 mmHg CO2 pneumoperitoneum treatment group and 15 mmHg CO2 pneumoperitoneum treatment group. Each group was divided into two subgroups respectively cultured for 1 h and 3 h. pH value of cell culture, cell growth curve, and cell cycle distribution of each group was measured. By application of scratch healing tests and Transwell chamber experiments, mobility ratio and number of cells through 8 µm membranes were measured to assess the migration ability of cells in each group after intervention. RESULTS Cell culture pH value of each subgroup in CO2 group decreased significantly after exposed in CO2 pneumoperitoneum (P < 0.01). The proliferation of GIST-T1 cells in 15 mmHg CO2 group was significantly inhibited early (1-2 days) (P < 0.05) and the proliferation of GIST-T1 cells in 8 mmHg CO2 1 h subgroup and 15 mmHg CO2 1 h subgroup was increased significantly late (4-6 days) (P < 0.05) after the interventions of CO2 pneumoperitoneum. The percentage of cells in G0-G1 phase increased, the percentage of S phase cells decreased (P < 0.01) in 1-h subgroup and 3-h subgroup of 15 mmHg CO2 group 24 h after exposure to CO2. The percentage of cells in S phase increased in 1-h subgroup of 8 mmHg CO2 group and decreased in 3-h subgroup of 15 mmHg CO2 group 72 h after exposure to CO2. In the Transwell chamber experiment, the cell number through 8-µm membrane increased significantly (P < 0.01) in 3-h subgroup of CO2 group compared to that in 3-h subgroup of control group. CONCLUSIONS The routine pressure and duration of CO2 pneumoperitoneum used in clinic did not promote the proliferation of gastrointestinal stromal tumors, but had a potential risk of increasing postoperative recurrence and distant metastasis.

Abstract
AIM To evaluate the costs of the introduction of a laparoscopic surgery program for gastric cancer in a Western community training hospital and tertiary referral centre for gastric cancer surgery.
METHODS All patients who underwent surgery for gastric cancer with curative intent in 2013 and 2014 were prospectively included. Primary outcomes were costs regarding surgery and hospital stay.
RESULTS Laparoscopic gastrectomy was used in 52 patients [mean age 68 years (± 9, range 50 to 87)] and open gastrectomy was used in 25 patients [mean age 70 years (± 10, range 46 to 85)]. Mean costs (in euro’s) of surgical instrumentation were significantly higher for laparoscopic surgery: 2270 ± 670 vs 1181 ± 680 in the open approach (P < 0.001). Costs of theatre use were higher in the laparoscopic group: mean 3819 ± 865 vs 2545 ± 1268 in the open surgery (P < 0.001). Total costs of hospitalization (i.e., costs of surgery and admission) were not different between laparoscopic and open surgery, 8187 ± 4864 and 7673 ± 8064 respectively (P = 0.729). Mean length of hospital stay was 9 ± 12 d in the laparoscopic group vs 14 ± 14 d in the open group (P = 0.044).
CONCLUSION The introduction of laparoscopic gastrectomy for gastric cancer coincided with higher costs for theatre use and surgical instrumentation compared to the open technique. Total costs were not significantly different due to shorter length of stay and less intensive care unit (ICU) admissions and shorter ICU stay in the laparoscopic group.

Abstract
Laparoscopy-assisted gastrectomy (LAG) has gained international acceptance for the treatment of early gastric cancer (EGC). However, the use of laparoscopic surgery in the management of advanced gastric cancer (AGC) has not attained widespread acceptance. This retrospective large-scale patient study in a single center for minimally invasive surgery assessed the feasibility and safety of LAG for T2 and T3 stage AGC. A total of 628 patients underwent LAG and 579 patients underwent open gastrectomy (OG) from Jan 2004 to Dec 2011. All cases underwent radical lymph node (LN) dissection from D1 to D2+. This study compared short- and long-term results between the 2 groups after stratifying by pTNM stages, including the mean operation time, volume of blood loss, number of harvested LNs, average days of postoperative hospital stay, mean gastrointestinal function recovery time, intra- and post-operative complications, recurrence rate, recurrence site, and 5-year survival curve. Thirty-five patients (5.57%) converted to open procedures in the LAG group. There were no significant differences in retrieved LN number (30.4 ± 13.4 vs 28.1 ± 17.2, P = 0.43), proximal resection margin (PRM) (6.15 ± 1.63 vs 6.09 ± 1.91, P = 0.56), or distal resection margin (DRM) (5.46 ± 1.74 vs 5.40 ± 1.95, P = 0.57) between the LAG and OG groups, respectively. The mean volume of blood loss (154.5 ± 102.6 vs 311.2 ± 118.9 mL, P < 0.001), mean postoperative hospital stay (7.6 ± 2.5 vs 10.7 ± 3.6 days, P < 0.001), mean time for gastrointestinal function recovery (3.3 ± 1.4 vs 3.9 ± 1.5 days, P < 0.001), and postoperative complications rate (6.4% vs 10.5%, P = 0.01) were clearly lower in the LAG group compared to the OG group. However, the recurrence pattern and site were not different between the 2 groups, even they were stratified by the TNM stage. The 5-year overall survival (OS) rates were 85.38%, 79.70%, 57.81%, 34.60% and 88.31%, 75.49%, 56.84%, 33.08% in patients with stage Ib, IIa, IIb, and IIIa, respectively, in the LAG and OG groups. There were no statistically significant differences in the OS rate for patients with the same TNM stage between the 2 groups. LAG with radical LN dissection is a safe and technically feasible procedure for the treatment of AGC staged below T3.

Abstract
Purpose This study presents findings on the clinical usefulness of an overlap method that is another modification for the currently well-known intracorporeal gastroduodenostomy in totally laparoscopic distal gastrectomy (TLDG). Methods We studied 42 patients diagnosed with gastric cancer who underwent TLDG between December 2011 and March 2013. Endoscopic linear staplers were used for intracorporeal anastomosis and patients were observed with endoscopic tracking six months after surgery. We retrospectively reviewed the outcome of the operation, the clinical pathological results, and the endoscopy results. Results The mean duration of the operation for 42 patients was 228.3 ± 42.5 minutes and the mean time to complete the anastomosis was 12.18 ± 2.3 minutes. There were no mortalities and no cases of open conversion. Following the operation, 37 patients had stage IA, 5 in stage IB, and 3 in stage II gastric cancer. Abscesses were seen in 3 patients and 5 cases of stasis during the postoperative period. Duodenoscopy 6 months after the operation showed 11 cases of gastric stasis, 28 cases of bile reflux, and 1 new case of erosive gastritis. We did not observe contraction in any of the patients. Conclusion The overlap method for intracorporeal gastroduodenostomy, using an endoscopic linear stapler, can be considered a feasible and safe technique for the treatment of stomach cancer. However, a long-term comparative study is required to sufficiently evaluate our findings.

Abstract
Purpose Although several studies report risk factors for anastomotic leakage after gastrectomy for gastric cancer, they have yielded conflicting results. The present retrospective cohort study was performed to identify risk factors that are consistently associated with anastomotic leakage after gastrectomy for stomach cancer. Materials and Methods All consecutive patients who underwent gastrectomy at a single gastric surgical unit between May 2003 and December 2012 were identified retrospectively. The associations between anastomotic leakage and 23 variables related to patient history, diagnosis, and surgery were assessed and analyzed with logistic regression. Results In total, 3,827 patients were included. The rate of anastomotic leakage was 1.88% (72/3,827). Multiple regression analysis showed that male sex (P=0.001), preoperative/intraoperative transfusion (P<0.001), presence of cardiovascular disease (P=0.023), and tumor location (P<0.001) were predictive of anastomotic leakage. Patients with and without leakage did not differ significantly in terms of their 5-year survival: 97.6 vs. 109.5 months (P=0.076). Conclusions Male sex, cardiovascular disease, perioperative transfusion, and tumor location in the upper third of the stomach were associated with an increased risk of anastomotic leakage. Although several studies have reported that an anastomotic complication has a negative impact on long-term survival, this association was not observed in the present study.

Abstract
AIM: To investigate the feasibility, advantages and disadvantages of two types of anvil insertion techniques for esophagojejunostomy after laparoscopic total gastrectomy.
METHODS: This was an open-label prospective cohort study. Laparoscopy-assisted radical total gastrectomy with D2 lymph node dissection was performed in 84 patients with primary non-metastatic gastric cancer confirmed by pre-operative histological examination. Overweight patients were excluded, as well as patients with peritoneal dissemination and invasion of adjacent organs. After total gastrectomy, all patients were randomized into two groups. Patients in Group I underwent esophagojejunostomy using a transorally-inserted anvil (OrVilTM), while patients in Group II underwent esophagojejunostomy using the hemi-double stapling technique (HDST). Both types of esophagojejunostomy were performed under laparoscopy. Patients’ baseline characteristics, preoperative characteristics, perioperative characteristics, short-term postoperative outcomes and operation cost were compared between the two groups. The primary endpoint was evaluation of the surgical outcome (operating time, time of digestive tract reconstruction and time of anvil insertion) and the medical cost of each operation (operation cost and total cost of hospitalization). The secondary endpoints were time to solid diet, post-surgical hospitalization time, time to defecation, time to ambulation and intra-operative blood loss. In addition, complications were assessed and compared.
RESULTS: Laparoscopic total gastrectomy and esophagojejunostomy were successfully performed in all 84 patients, without conversion to laparotomy. There were no significant differences in the operative time and time for total gastrectomy between the two groups (287.8 ± 38.4 min vs 271.8 ± 46.1 min, P = 0.09, and 147.7 ± 31.6 min vs 159.8 ± 33.8 min, P = 0.09, respectively). The time for digestive tract reconstruction and for anvil insertion were significantly decreased in Group II compared with Group I (47.8 ± 12.1 min vs 55.4 ± 15.7 min, P = 0.01, and 12.6 ± 4.7 min vs 18.7 ± 7.5 min, P = 0.001, respectively). Intra-operative blood loss (96.4 ± 32.7 mL vs 88.2 ± 36.9 mL, P = 0.28), time to defecation (3.5 ± 0.9 d vs 3.2 ± 1.1 d, P = 0.12), time to ambulation (3.9 ± 0.7 d vs 3.6 ± 1.1 d, P = 0.12), time to solid diet (7.6 ± 1.4 d vs 8.0 ± 2.7 d, P = 0.31) and total hospitalization (10.6 ± 2.6 d vs 10.8 ± 3.5 d, P = 0.80) were similar between the two groups. In addition, the total costs of hospitalization were similar between the two groups (73848.7 ± 11781.0 RMB vs 70870.3 ± 14003.5 RMB, P = 0.296), but operation cost was significantly higher in Group I compared with Group II (32401.9 ± 1981.6 RMB vs 26961.9 ± 2293.8 RMB, P < 0.001).
CONCLUSION: Anvil insertion was faster and easier using the HDST technique compared with OrVilTM, and was more cost-effective. There was no significant difference in safety.

Abstract
OBJECTIVE To compare the short-term outcomes of gastric cancer patients treated with robotic gastrectomy (RG) or laparoscopic gastrectomy (LG). INTRODUCTION Robotic gastrectomy (RG) has been used for gastric cancer since 2002. This meta-analysis evaluates the safety and efficacy of robotic gastrectomy (RG) and conventional laparoscopic gastrectomy (LG) for gastric cancer. MATERIAL AND METHODS Pubmed, Embase and The Cochrane Library were searched, and manual searches were performed up to March 31, 2013. Five non-randomized control trials that reported RG and LG for gastric cancer were included. Outcomes evaluated were operation time, number of retrieved LN, blood loss, the length of the resection margin, complications, length of postoperative hospital stay. RESULTS Of 1796 patients in five studies, 551 were allocated to RG and 1245 to LG. Operation time was significantly shorter in the latter group (weighted mean difference 42.9; 95 % confidence interval 20.87 to 64.92 min; p < 0.05). Blood loss weighted mean difference was -16.07 (95 % confidence interval -32.78 to 0.64 mL; p < 0.05) and postoperative stay weighted mean difference was -1.98 (95 % confidence interval -3.66 to -0.3 days; p < 0.05); both were less in the RG group. LN, length of the resection margin, and postoperative complications were similar in both groups. CONCLUSION It may be concluded that RG is a safe and comfortable alternative to LG and is justifiable in the light of clinical trials.

Abstract
Tumor localization during intracorporeal anastomosis after totally laparoscopic distal gastrectomy (TLDG) is challenging. The aim of this study was to assess the simplicity and feasibility of locating tumors in the stomach using radio-opaque markers and preoperative endoscopic clipping. The intra- and postoperative findings of 29 patients who underwent TLDG with intracorporeal anastomosis between January 2012 and March 2013 were reviewed. Preoperative endoscopic clips were applied just proximal to the tumor by specialized endoscopists, and surgical gauze with an attached radio-opaque marker (3 mm x 60 mm) was prepared. The marker was fixed to either the anterior or posterior of the stomach, above the predicted site of the tumor, using suture ties. Portable abdominal radiography was used during the laparoscopic surgery, and the stomach was resected using guidance by the radiomarker. The radio-opaque marker and the endoscopic clips were clearly visible by intraoperative abdominal radiography. All patients received curative resection. No complications or deaths were encountered. The mean distance between the endoscopic clips and the radiomarker by portable intraoperative radiography was 21.3 ± 18.3 mm, whereas the actual in situ mean distance was 20.7 ± 17.6 mm. This difference was not statistically significant ( P > 0.05). It is imperative that preoperative endoscopic clips are applied just proximal to the tumor by specialized endoscopists. The use of a radio-opaque marker is a simple and feasible way to locate tumors during totally laparoscopic gastrectomy.

Abstract
OBJECTIVE Laparoscopic surgery may offer advantages compared to open surgery, such as earlier mobilization, less pain and lower post-surgical morbidity. Surgical stress is thought to be associated with the postoperative immunological changes in the body as an impaired immune function, which may lead to an increased susceptibility to complications and morbidity. The aim of this review was to investigate if laparoscopic surgery reduces the immunological response compared to open surgery in gastric cancer. METHODS We conducted a literature search identifying relevant studies comparing laparoscopy or laparoscopic-assisted surgery with open gastric surgery. The main outcome was postoperative immunological status defined as surgical stress parameters, including inflammatory cytokines and blood parameters. RESULTS We identified seven studies that addressed the immunological status in patients undergoing laparoscopic or laparoscopy-assisted surgery compared to open surgery. IL-6 in circulation was found to be significantly reduced in laparoscopic patients. Furthermore, the plasma concentration of C-reactive protein was significantly lower in laparoscopic patients compared to patients undergoing laparotomy. Finally, most studies reported lower levels of white blood cell count in laparoscopic patients, although this result did not reach statistical significance in a small number of studies. CONCLUSIONS Laparoscopy-assisted gastric surgery seems to attenuate the immune response compared to open surgery. Larger and prospective studies are needed to further evaluate if the immunological status is relatively preserved in minimal invasive surgery and if this may reduce the postoperative complications compared to open surgery.

Abstract
AIM: To compare the short-term clinical outcomes of robot-assisted gastrectomy (RAG) with laparoscopy-assisted gastrectomy (LAG) in gastric cancer patients.
METHODS: Articles were identified through a literature search of Pubmed, EMBASE, Scopus, Web of Science, Chinese National Knowledge Infrastructure and the Cochrane Library. Weighted mean differences (WMDs) and odds ratios (ORs) were selected as effect sizes for quantitative variables and qualitative variables, respectively. And 95%CIs were also calculated.
RESULTS: A total of 13 studies with 3518 patients were included. RAG was associated with longer operative time (WMD = 46.26 min, 95%CI: 31.89-60.63, P < 0.00001), less blood loss [WMD = -37.19 mL, 95%CI: -60.16-(-14.23), P = 0.002] and shorter postoperative hospital stay [WMD = -0.65 d, 95%CI: -1.24-(-0.05), P = 0.03] than LAG. No significant difference in the numbers of retrieved lymph nodes was found between the two groups (WMD = 1.46, 95%CI: -0.19-3.10, P = 0.08). There was no significant difference in mortality (OR = 1.55, 95%CI: 0.49-4.94, P = 0.45), overall complications (OR = 1.00, 95%CI: 0.80-1.26, P = 0.98), anastomosis leakage (OR = 1.02, 95%CI: 0.62-1.65, P = 0.95) and anastomosis stenosis rates (OR = 0.54, 95%CI: 0.18-1.57, P = 0.25).
CONCLUSION: RAG is effective and safe in the treatment of gastric cancer. RAG is a promising alternative to laparoscopic surgery. Long-term randomized controlled studies with large scale and improved designs are needed to further evaluate the long-term outcomes.

Abstract
We report the sonographic findings in a case of dropped omental fat post laparoscopy-assisted distal gastrectomy with omentectomy for stomach cancer mistaken for malignant intraperitoneal seeding. Gray-scale sonography revealed an ovoid-shaped hyperechoic mass with central poorly defined hypoechoic portion in the right perihepatic space. Color Doppler sonography showed no blood flow within the mass. Contrast-enhanced CT scan of the liver revealed an oval-shaped fatty mass with a CT number of -100 HU

Abstract
BACKGROUND Laparoscopic total gastrectomy (LTG) is a challenging surgical procedure that has substantial technical difficulties and complications. In this study, we investigated risk factors for morbidity and mortality after LTG, and the learning curve associated with postoperative morbidity. METHODS Prospectively constructed data of 203 patients undergoing LTG between 2004 and 2013 were retrospectively reviewed. The multivariate logistic regression model was used to analyze risk factors for postoperative morbidity. The Cumulative Sum (CUSUM) technique was used to assess the learning curve. RESULTS Postoperative morbidity and mortality after LTG was 18.7 and 1.5 %, respectively. Of 38 patients with postoperative morbidity, 7 (3.4 %) were managed with reoperation, 8 (4.0 %) with radiologic or endoscopic intervention, and 23 (11.3 %) with a conservative treatment. Of local complications, gastrointestinal bleeding was the most common (12 patients), followed by anastomosis leakage (9 patients) and intra-abdominal abscess (9 patients). Respiratory complication was the most common of the systemic complications. There were 17 cases (8.4 %) of complications exceeding grade III severity, of which anastomosis leakage was the most common. CUSUM analysis showed that postoperative morbidity reached a plateau after around 45 cases. Univariate and multivariate analyses revealed that old age (over 65 years of age) and surgical experience (<45 cases) were independent factors for postoperative morbidity after LTG. CONCLUSION LTG is a feasible technique with acceptable morbidity and mortality. However, substantial surgical experience is of most importance to reduce postoperative morbidity and mortality.

Abstract
BACKGROUND Intraoperative identification of early gastric cancer is difficult to conduct during laparoscopic procedures. In this study, we investigated the feasibility and accuracy of a newly developed marking system using endoclips with radio frequency identification (RFID) tags in a canine model. METHODS RFID is a wireless near field communication technology. Among the open frequency bands available for medical use, 13.56 MHz is suitable for a surgical marking system because of the similar and linear signal decay both in air and in biological tissues. The proposed system consists of four parts: (a) endoclips with RFID tags, (b) endo-clip applier equipment, (c) laparoscopic locating probe, and (d) signal processing units with audio interface. In the experimental setting using canine models, RFID-tagged endoclips were applied to the mucosa of each dog's stomach. During the subsequent operation, the clips with RFID tags placed in five dogs were located by the detection of the RFID signal from the tag (RFID group), and the conventional clips in the other six dogs were located by finger palpation (FP group). The detected sites were marked by ablation on the serosal surface. Distance between the clips and the metal pin needles indicating ablated sites were measured with X-ray radiographs of the resected specimen. RESULTS All clips were successfully detected by the marking system in the RFID group (10/10) and by finger palpation in the FP group (17/17). The medians of detection times were 31.5 and 25.0 s, respectively; the distances were 5.63 and 7.62 mm, respectively. The differences were not statistically significant. No adverse event related to the procedures was observed. CONCLUSIONS Endoclips with RFID tags were located by our novel marking system in an experimental laparoscopic setting using canine stomachs with substantial accuracy comparable to conventional endoclips located by finger palpation through an open approach.

Abstract
BACKGROUND This literature review focuses on the potential benefits and eventual limitations of robotic surgery with respect to the traditional minimally invasive laparoscopic surgical technique for gastric cancer. METHODS A literature survey was performed using specific search phrases in PubMed. Series including < 10 cases and series including only an 'open group' of patients in comparison with the 'robotic group' were excluded. Characteristics such as patient demographics, perioperative outcomes and oncological results were analysed. RESULTS According to the analysis of 12 series, robotic gastric surgery has been shown to be a safe and feasible method. However, a considerable number of studies are composed of early-stage gastric cancer cases and there seems to be a lack of randomized controlled studies. CONCLUSIONS Large prospective randomized studies are still required in order to demonstrate the exact benefits of robotic surgery and its effects on survival in gastric cancer.

Abstract
BACKGROUND To assess the safety of transorally-inserted anvil (TOA) for use during esophagojejunostomy (EJ) reconstruction during laparoscopic total gastrectomy (LTG). METHODS Between March 2009 and December 2011, 39 consecutive open total gastrectomies (OTGs) and 36 LTGs using TOA for gastric cancer were comparatively evaluated. We investigated postoperative complications, using the Clavien-Dindo classification. To evaluate the effect of a learning period in using TOA for LTG, we also investigated shifts in the patterns of complications and changes in total operation time over the course of the study. RESULTS The patient characteristics at baseline were not different between both groups, except for the extent of lymphadenectomy (P < 0.001) and depth of tumor invasion (P = 0.003). Multivariate analysis revealed that TOA usage elevated the occurrence of infectious complications significantly (OR = 3.32, P = 0.042), but was not associated with EJ-related complications. TOA usage did not need a learning period for the length of time required to complete the operation, or the likelihood of developing an EJ-related or infectious complication. CONCLUSIONS TOA use for EJ during LTG is relatively simple and easy enough not to require a learning period for surgeons. This procedure did not elevated the occurrence of EJ-related complications compared to circular stapling in open surgery, but it does require special prevention efforts to avoid infectious complications.

Abstract
Aim To evaluate the safety and efficacy of robotic gastrectomy versus open gastrectomy for gastric cancer. Methods A comprehensive search of PubMed, EMBASE, Cochrane Library, and Web of Knowledge was performed. Systematic review was carried out to identify studies comparing robotic gastrectomy and open gastrectomy in gastric cancer. Intraoperative and postoperative outcomes were also analyzed to evaluate the safety and efficacy of the surgery. A fixed effects model or a random effects model was utilized according to the heterogeneity. Results Four studies involving 5780 patients with 520 (9.00%) cases of robotic gastrectomy and 5260 (91.00%) cases of open gastrectomy were included in this meta-analysis. Compared to open gastrectomy, robotic gastrectomy has a significantly longer operation time (weighted mean differences (WMD) =92.37, 95% confidence interval (CI): 55.63 to 129.12, P<0.00001), lower blood loss (WMD: -126.08, 95% CI: -189.02 to -63.13, P<0.0001), and shorter hospital stay (WMD = -2.87; 95% CI: -4.17 to -1.56; P<0.0001). No statistical difference was noted based on the rate of overall postoperative complication, wound infection, bleeding, number of harvested lymph nodes, anastomotic leakage and postoperative mortality rate. Conclusions The results of this meta-analysis suggest that robotic gastrectomy is a better alternative technique to open gastrectomy for gastric cancer. However, more prospective, well-designed, multicenter, randomized controlled trials are necessary to further evaluate the safety and efficacy as well as the long-term outcome.

Abstract
Gastric cancer is the fourth most common cancer type and is the second leading cause of cancer deaths worldwide. The contemporary treatment is gastrectomy and lymphadenectomy, which can be accomplished by either conventional (open), or laparoscopic surgery. With the advances in technology, there is a paradigm shift from conventional laparoscopy. As a result, single incision laparoscopic surgery (SILS), natural orifice transluminal endoscopic surgery (NOTES), and robot assisted laparoscopic surgery (RALS) have evolved as new treatment options for minimal invasive surgery. Herein five patients who were treated via robot assisted laparoscopic gastrectomy were reported together with review of the literature.

Abstract
In recent decades, laparoscopy assisted distal gastrectomy (LADG) has been introduced to treat early gastric cancer (EGC). This study evaluated the safety and efficacy of laparoscopy assisted and conventional open distal gastrectomy for EGC. Comprehensive searches of PubMed, EmBase, Cochrane Controlled Trials Register and Chinese Biomedical Database (CBM) were performed. Included literature was evaluated using the Newcastle-Ottawa Scale. Original data were extracted, pooled odds ratio (OR) and 95% confidence intervals (CI) were calculated using RevMan 5.0. Eight RCTs of 734 patients were included in the study. Compared to CODG, LADG increases the operation time (weighted mean difference [WMD]: 63.35; 95% confidence interval [CI]: 57.96, 68.74; P<0.01), reduces intraoperative blood loss (WMD: -127.95; 95% CI: -147.97, -107.93; P<0.01), decreases number of harvested lymph nodes (WMD: -4.21; 95% CI: -6.10, -2.31; P<0.01), forwards oral intake time (WMD:-0.43; 95% CI: -0.61, -0.24; P<0.01), and shortens hospital stay(WMD: -1.29; 95% CI: -1.76, -0.83; P<0.01). There is no significant difference in postoperative complications(OR: 0.70; 95% CI: 0.46, 1.06; P=0.09). All these findings indicate that LADG for EGC is feasible and safe.

Abstract
BACKGROUND The purpose of this study was to evaluate laparoscopy-assisted distal gastrectomy (LADG) compared to open distal gastrectomy (ODG) in the treatment of early gastric cancer with respect to survival, surgical outcomes, complications, and quality of life (QOL). METHODS One hundred sixty-four patients with cT1N0M0 and cT1N1M0 distal gastric cancer were randomly assigned to either the LADG group or the ODG group. The primary end point was the 5-year disease-free survival (DFS) rate. Complications were classified using the accordion severity classification of postoperative complications scheme. QOL was measured using the European Organization for Research and Treatment of Cancer QLQ-C30 and QLQ-STO22 preoperatively and postoperatively during regular follow-up visits. This trial is registered at ClinicalTrials.gov (NCT00546468). RESULTS The median (range) follow-up period was 74.3 (24.8-90.8) months. The LADG and ODG groups showed similar survival [5-year DFS rate: 98.8 % vs. 97.6 %, respectively (P = 0.514), 5-year overall survival (OS) rate: 97.6 vs. 96.3 %, respectively (P = 0.721)] or overall complication rate (29.3 vs. 42.7 %, respectively; P = 0.073). Mild complications were significantly less frequent in the LADG group than in the ODG group (23.2 vs. 41.5 %; P = 0.012). The rates of moderate, severe, and long-term complications (i.e., 31 days to 5 years after surgery) did not differ significantly between groups. No clinically meaningful differences were detected between the two groups in long-term QOL. CONCLUSION LADG showed similar DFS and OS compared to ODG in treating early gastric cancer. Marginal benefits in mild complications were observed with LADG. LADG did not show advantages over ODG regarding other complications and long-term QOL.

Abstract
BACKGROUND The technique of totally laparoscopic total gastrectomy (TLTG) has been developed for gastric cancer, but its feasibility and surgical outcomes remain unclear. This is the first study comparing the early surgical outcomes of TLTG with those of conventional open total gastrectomy (OTG) for gastric cancer. PATIENTS AND METHODS Between January 2011 and December 2011, 139 patients underwent TLTG, and 207 patients underwent OTG for gastric cancer; surgical procedures were selected by means of preoperative diagnostic tests under T3N2M0. Clinicopathologic characteristics and early surgical outcomes in the two groups were compared retrospectively. RESULTS There were no significant difference in preoperative characteristics between the two groups, and the durations of surgery were not significantly different. However, TLTG was superior to OTG in terms of time to first flatus, time to commencement of soft diet, pain score (visual analog scale), need for analgesics, length of hospital stay, and overall postoperative complications (each P<.05). The median number of lymph nodes harvested was significantly higher in the TLTG group (37 versus 34; P=.039). Resection margins were negative in all patients. CONCLUSIONS TLTG should be considered as a safe and practicable alternative to OTG for the treatment of gastric cancer. Moreover, it is less invasive and results in faster recovery than OTG.

Abstract
BACKGROUND Many reconstructive procedures have been developed in an effort to resolve complications after total gastrectomy (TG). However, anatomical disruption of the esophagogastric junction, especially the low esophageal sphincter, still occurs so that postoperative complications continue to arise. In this study, we developed a procedure for intracorporeal laparoscopic Roux-en-Y gastrojejunostomy (RYGJ) after 95% (near-total) gastrectomy, to reduce postoperative complications in early gastric cancer (EGC) of the upper third of the stomach. PATIENTS AND METHODS Laparoscopic RYGJ after 95% gastrectomy was performed on 21 patients with EGC in the upper third of the stomach between May 2011 and April 2012 in Asan Medical Center, Seoul, Korea. The resection line of the stomach was marked using metallic preoperative endoscopic clips and intraoperative laparascopic vessel clips together with a portable abdominal radiograph. Approximately 95% of the stomach was transected using an endoscopic linear stapler, and an antecolic side-to-side gastrojejunal anastomosis was created between the posterior side of the gastric remnant and the antimesenteric side of the jejunal limb, also using an endoscopic linear stapler. The entry hole was first closed in approximate fashion with three sutures, and closure was completed with an endoscopic linear stapler. RESULTS Intracorporeal laparoscopic RYGJ after 95% gastrectomy was successfully performed in all patients. No patients required conversion to open surgery or other laparoscopic anastomosis techniques. No postoperative complications occurred. All patients had tumor-free resection margins, and there was no mortality. CONCLUSIONS Intracorporeal laparoscopic RYGJ after 95% gastrectomy can be performed easily and safely. We recommend this method over laparoscopic TG or open TG for treatment of EGC in the upper third of the stomach.

Abstract
BACKGROUND The stomach is the most common site for gastrointestinal stromal tumors (GIST) development. Surgical treatment consists of excision of the entire neoplastic mass, with sufficient surgical margins within healthy tissue. This can be achieved with different techniques ranging from wedge resections, typical gastric resections, right up to total gastrectomy. There aren't clear guidelines for the use of minimally invasive approach. MATERIALS AND METHODS From January 2011 to April 2012, 5 patients with presumed preoperative diagnosis of GIST were treated by robotic surgery at the Unit of Surgery and Advanced Oncologic Therapies, Forlì Hospital, Forlì, Italy. We report operative techniques, perioperative outcomes and follow-up. RESULTS Lesions were localized at anterior wall of gastric antrum (N = 2) and near pyloric area (N = 3). Mean tumor size was 5 cm (range 4-7 cm). Surgical procedures were 5 distal gastrectomy. None intervention was converted to open surgery and there weren't major intraoperative complications. Median operative time was 240 min (range 210-300 min) and mean intraoperative blood loss was 96 ml (80-120 ml). All lesions had microscopically negative resection margins. Median follow-up was 13.5 months (range 12-15 months) with a disease-free survival rate of 100%. CONCLUSIONS Surgical robotic approach for large GISTs is feasibility and new evidences are needed to clarify the effective role of different surgical strategies.

Abstract
BACKGROUND Laparoscopic gastrectomy is a new and technically challenging surgical procedure with potential benefit. The objective of this study was to investigate clinical and para-clinical consequences following Roux-en-Y and Jejunal Loop interposition reconstructive techniques for subtotal gastrectomy using laparoscopic assisted surgery. RESULTS Following resection of the stomach attachments through a laparoscopic approach, stomach was removed and reconstruction was performed with either standard Roux-en-Y (n = 5) or Jejunal Loop interposition (n = 5) methods. Weight changes were monitored on a daily basis and blood samples were collected on Days 0, 7 and 21 post surgery. A fecal sample was collected on Day 28 after surgery to evaluate fat content. One month post surgery, positive contrast radiography was conducted at 5, 10, 20, 40, 60 and 90 minutes after oral administration of barium sulfate, to evaluate the postoperative complications. There was a gradual decline in body weight in both experimental groups after surgery (P < 0.05). There was no difference in blood parameters at any time after surgery between the two methods (P > 0.05). Fecal fat content increased in the Roux-en-Y compared to the Jejunal loop interposition technique (P < 0.05). No major complications were found in radiographs and gastric emptying time was similar between the two groups (P > 0.05). CONCLUSION Roux-en-Y and Jejunal loop interposition techniques might be considered as suitable approaches for reconstructing gastro-intestinal tract following gastrectomy in dogs. The results of this study warrant further investigation with a larger number of animals.

Abstract
BACKGROUND The role of laparoscopic surgery for the treatment of gastric cancer is still controversial, particularly in terms of oncologic efficacy. The aim of this study was to compare short-term outcomes of laparoscopic and open resection for gastric cancer at a single Western institution. SUBJECTS AND METHODS This study was designed as a matched cohort study from a prospective gastric cancer database. Forty-one patients undergoing laparoscopic gastrectomy for gastric cancer between June 2008 and January 2012 were matched with 41 patients undergoing open gastrectomy in the same time period. Patient pairing was done according to age, gender, type of gastrectomy (subtotal or total), and tumor stage via a randomized statistical method. The short-term outcomes and oncologic adequacy of the laparoscopic and open procedures were compared. A D2 lymph node dissection was performed in the majority of patients in both groups. RESULTS The two study groups were similar with respect to patient and tumor characteristics. Laparoscopic procedures were associated with a decreased blood loss (118.7 versus 312.4 mL, P<.005), incidence of surgery-unrelated complications (3 versus 9 patients, P<.05), and duration of hospital stay (8.1 versus 11.5 days, P<.05) but increased operative time for both subtotal (223.5 versus 158.2 minutes, P<.001) and total (298.1 versus 185.5 minutes, P<.001) gastrectomies. The mean number of retrieved lymph nodes after D2 dissection was similar: 30.0 for laparoscopic and 29.7 for open patients. CONCLUSIONS Within the limitations of a nonrandomized analysis, this study shows that the laparoscopic approach is a safe and oncologically adequate option for the treatment of gastric cancer, which compares favorably with open gastrectomy in short-term outcomes.

Abstract
We report here a case of reexpansion pulmonary edema following laparoscopy-assisted distal gastrectomy (LADG) for early gastric cancer. A 57-year-old Japanese woman with no preoperative comorbidity was diagnosed with early gastric cancer. The patient underwent LADG using the pneumoperitoneum method. During surgery, the patient was unintentionally subjected to single-lung ventilation for approximately 247 minutes due to intratracheal tube dislocation. One hour after surgery, she developed severe dyspnea and produced a large amount of pink frothy sputum. Chest radiography results showed diffuse ground-glass attenuation and alveolar consolidation in both lungs without cardiomegaly. A diagnosis of pulmonary edema was made, and the patient was immediately intubated and received ventilatory support with high positive end-expiratory pressure. The patient gradually recovered and was weaned from the ventilatory support on the third postoperative day. This case shows that single-lung ventilation may be a risk factor for reexpansion pulmonary edema during laparoscopic surgery with pneumoperitoneum.

Abstract
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±74.54 minutes vs. 192.56±39.56 minutes, P>0.001), and hospital stay (14.40±24.93 days vs. 8.66±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±5.39 days vs. 8.11±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±84.59 ml vs. 173.45±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.

Abstract
OBJECTIVE To evaluate the safety and efficacy of laparoscopy-assisted distal gastrectomy (LADG) in patients with early gastric cancer (EGC) to determine whether LADG is an acceptable alternative to open distal gastrectomy (ODG). BACKGROUND LADG combined with less than D2 or D2 lymphadenectomy for EGC is still a controversial surgical intervention for its uncertain oncological safety and economic benefit. We conducted this systematic review and meta-analysis that included randomized control trials (RCTs) and non-RCTs of LADG versus ODG to evaluate whether the safety and efficacy of LADG in patients with EGC are equivalent to those of ODG. METHODS A comprehensive search of PubMed, EMBASE, Cochrane Library, and China Knowledge Resource Integrated Database was performed. Eligible trials published between January 1, 1994, and December 31, 2010, were included in the study. Data synthesis and statistical analysis were carried out by RevMan 5.0 software. The quality of evidence was assessed by GRADEpro 3.2.2. RESULTS Twenty-two studies with 3411 participants were included in this study. The mean number of lymph nodes retrieved in LADG was close to that retrieved in ODG (in the less than D2 resection: weighted mean difference [WMD] = -1.79; 95% confidence interval [95% CI], -5.78 to 2.19; P = 0.38; heterogeneity: P < 0.00001, I = 98%; and in the D2 resection: WMD = -1.53; 95% CI, -3.56 to 0.51; P = 0.14; heterogeneity: P = 0.23, I = 26%). The overall postoperative morbidity was significantly less in LADG than in ODG (relative risk = 0.58; 95% CI, 0.46-0.74; P < 0.00001; heterogeneity: P = 0.94, I = 0%). LADG reduced the intraoperative blood loss, postoperative analgesic consumption, and hospital duration, without increasing the total hospitalization costs and cancer recurrence rate. The long-term survival rate of patients undergoing LADG was similar to that of patients undergoing ODG. However, LADG was still a technically dependent and time-consuming procedure. Conversion rate of LADG was 0% to 2.94%. The reported reasons for conversion were bleeding, adhesion, and safety resection margin requirement. LIMITATIONS : There were potential biases and significant heterogeneity in some clinical outcome measures in this study. Methodologically high-quality controlled clinical trials were sparse for this new surgical intervention. According to The Grading of Recommendations Assessment, Development and Evaluation approach, when assessing the safety and efficacy of LADG by comparing with those of ODG with the defined clinical outcomes in patients with EGC, the quality of the currently available clinical evidence was very low. CONCLUSIONS LADG may be a technically feasible alternative for EGC when it is performed in experienced surgical centers in which patients undergoing LADG may benefit from the faster postoperative recovery. However, the currently available evidence cannot exclude the potential clinical benefits or harms, especially in the node-positive cases. Methodologically high-quality comparative studies are needed for further evaluation.

Abstract
BACKGROUND Robotic gastrectomy (RG) for gastric cancer remains controversial. The main aim of this meta-analysis was to compare the safety and efficacy of robotic gastrectomy (RG) and conventional laparoscopic gastrectomy (LG) for gastric cancer. METHODS Literature searches of electronic databases (PubMed, Embase, Cochrane Library Ovid, and Web of Science databases) and manual searches up to December 30, 2011 were performed. Comparative clinical trials were eligible if they reported perioperative outcomes for RG and LG for gastric cancer. Fixed and random effects models were used. The RevMan 5.1 was used for pooled estimates. RESULTS Three NRCTs enrolling 918 patients (268 in the RG group and 650 in the LG group) were included in the meta-analysis. RG for gastric cancer was associated with a significantly longer operative time (WMD: 68.77, 95% CI: 35.09-102.45; P < 0.0001), but significantly less intraoperative blood loss (WMD: -41.88, 95% CI: -71.62 to -12.14; P = 0.006). We found no significant differences in the number of lymph nodes (WMD: -0.71, 95% CI: -6.78 to 5.36; P = 0.82), overall morbidity (WMD: 0.74, 95% CI: 0.47 to 1.16; P = 0.19), perioperative mortality rates (WMD: 1.80, 95% CI: 0.30 to 10.89; P = 0.52) and length of hospital stay (WMD: 0.42, 95% CI: -1.87 to 0.79; P = 0.42) between the two groups. CONCLUSIONS It may be concluded that RG is a safe and effective alternative to LG and is justifiable under the setting of clinical trials. Additional RCTs that compare RG and LG and investigate the long-term oncological outcomes are required to determine potential advantages or disadvantages of RG.

Abstract
Through the advent of surgical techniques and the improvement of laparoscopic tools including the ultrasonic activated scissor, laparoscopic gastrectomy has been increasingly used in far more cases of benign or malignant gastric lesions for the benefit of patients without compromising therapeutic outcomes. Even though possible complications provoked by the ultrasonic activated scissor can be prevented during the procedure with increasing advanced laparoscopic experience and supervision, unexpected late complications after the operations rarely occur. An extremely rare case of left incarcerated diaphragmatic hernia of the transverse colon developed in an 81-year-old female patient as a late complication, 8 months after laparoscopy-assisted total gastrectomy for gastric cancer, with laparoscopy successfully resumed and without the need to sacrifice any portion of the bowel.

Abstract
Stomach cancer is one of the most common cancers worldwide, despite its declining overall incidence. Although there are differences in incidence, etiology and pathological factors, most studies do not separately analyze cardia and noncardia gastric cancer. Surgery is the only potentially curative treatment for advanced, resectable gastric cancer, but locoregional relapse rate is high with a consequently poor prognosis. To improve survival, several preoperative and postoperative treatment strategies have been investigated. Whereas perioperative chemotherapy and postoperative chemoradiation (CRT) are considered standard therapy in the Western world, in Asia postoperative monochemotherapy with S-1 is often used. Several other therapeutic options, although generally not accepted as standard treatment, are postoperative combination chemotherapy, hyperthermic intraperitoneal chemotherapy and preoperative radiotherapy and CRT. Postoperative combination chemotherapy does show a statistically significant but clinically equivocal survival advantage in several meta-analyses. Hyperthermic intraperitoneal chemotherapy is mainly performed in Asia and is associated with a higher postoperative complication rate. Based on the currently available data, the use of postoperative radiotherapy alone and the use of intraoperative radiotherapy should not be advised in the treatment of resectable gastric cancer. Western randomized trials on gastric cancer are often hampered by slow or incomplete accrual. Reduction of toxicity for preoperative and especially postoperative treatment is essential for the ongoing improvement of gastric cancer care.

Abstract
BACKGROUND Knowledge of the intraoperative location of lesions is a prerequisite for deciding the proper extent of gastric resection or the choice of anastomosis technique during totally laparoscopic distal gastrectomy (TLDG) for early gastric cancer (EGC). In this study we introduce a novel tumor localization method for TLDG: endoscopic blood tattooing. METHODS Twenty-three consecutive patients scheduled for TLDG for EGC were enrolled in this prospective study. The day before surgery, 2-3 ml of autologous blood was injected into the gastric muscle layer at 3-4 cm proximal to the lesion during endoscopy. RESULTS The study subjects consisted of 15 males and 8 females with a mean age of 61 ± 10.4 years. During surgery, the endoscopic blood tattooed sites were successfully identified in all 23 patients. No complications associated with the procedure occurred, and no patient had microscopic residual tumor cells at the proximal resection margin, with a mean proximal margin length of 3.3 ± 2.7 cm. Eighteen patients underwent TLDG with Billroth II anastomosis, four patients with Roux-en-Y gastrojejunostomy, and one patient with laparoscopic total gastrectomy. At final pathologic examinations, 20 patients were of stage IA and 3 were of stage IB according to the UICC TNM classification (6th ed.). CONCLUSIONS Endoscopic blood tattooing provides a simple and useful means of localizing lesions during TLDG for EGC. Although the superiority of this technique over other localization methods needs to be evaluated further, the authors recommend endoscopic blood tattooing as an alternative to other intraoperative localization methods for laparoscopic surgery for EGC.

Baek SJ, Lee DW, Park SS, Kim SH. Current status of robot-assisted gastric surgery. World J Gastrointest Oncol 2011; 3:137-43. [PMID: 22046490 PMCID: PMC3205112 DOI: 10.4251/wjgo.v3.i10.137] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/23/2010] [Revised: 10/04/2011] [Accepted: 10/10/2011] [Indexed: 02/05/2023] Open
Abstract
In an effort to minimize the limitations of laparoscopy, a robotic surgery system was introduced, but its role for gastric cancer is still unclear. The objective of this article is to assess the current status of robotic surgery for gastric cancer and to predict future prospects. Although the current study was limited by its small number of patients and retrospective nature, robot-assisted gastrectomy with lymphadenectomy for the treatment of gastric cancer is a feasible and safe procedure for experienced laparoscopic surgeons. Most studies have reported satisfactory results for postoperative short-term coutcomes, such as: postoperative oral feeding, gas out, hospital stay and complications, compared with laparoscopic surgery; the difference is a longer operation time. However, robotic surgery showed a shallow learning curve compared with the familarity of conventional open surgery; after the accumulation of several cases, robotic surgery could be expected to result in a similar operation time. Robotic-assisted gastrectomy can expand the indications of minimally invasive surgery to include advanced gastric cancer by improving the ability to perform lymphadenectomy. Moreover, ”total” robotic gastrectomy can be facilitated using a robot-sewing technique and gastric submucosal tumors near the gastroesophageal junction or pylorus can be resected safely by this novel technique. In conclusion, robot-assisted gastrectomy may offer a good alternative to conventional open or laparoscopic surgery for gastric cancer, provided that long-term oncologic outcomes can be confirmed.

Open vs robot-assisted laparoscopic gastric resection with D2 lymph node dissection for adenocarcinoma: a case-control study. Int J Med Robot 2011; 7:452-8. [PMID: 21984205 DOI: 10.1002/rcs.416] [Citation(s) in RCA: 69] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2011] [Revised: 06/06/2011] [Accepted: 06/16/2011] [Indexed: 12/12/2022]
Abstract
BACKGROUND A population-based case-control study was conducted in order to investigate the advantages of robot-assisted gastric resection (RGR) for gastric cancer as opposed to traditional open gastrectomy (OG). METHODS Data were collected in two prospectively maintained databases on patients who underwent a D2 gastrectomy with curative intent for primary gastric adenocarcinoma. All (n = 29) the first consecutive gastric cancer patients submitted to RGR from a referral centre for minimally invasive surgery were matched to control cancers (n = 120) extrapolated from a high volume centre database including patients submitted to OG. RESULTS Robot-assisted laparoscopic procedures implied increased operative time (290 vs 222 min, p = 0.004), decreased blood loss (197.6 vs 386.1 mL, p = 0.0001) and shorter hospital stay (9.6 vs 13.4 days, p < 0.0009). There was no difference in the mean number of harvested lymph nodes between the two groups (28.0 vs 31.7, p = 0.023). The total morbidity rate, including major complications such as anastomotic and duodenal suture failure, was comparable between groups (41.4% vs 42.5%; in the RGR and OG, respectively, p = 0.764). Preliminary data on overall survival did not show prognostic differences between the two groups (p = 0.615). CONCLUSIONS Robot-assisted surgery fulfils oncologic criteria for D2 dissection and has an oncologic outcome comparable with that of OG. RGR resulted in shorter hospital stays, the loss of less blood and morbidity comparable with that of OG. Randomized clinical trials and longer follow-up are needed to evaluate whether RGR achieves long-term survival rates equivalent to that of open and laparoscopic surgery.

Abstract
BACKGROUND Widespread diffusion of minimally-invasive surgery for gastric cancer treatment is limited by the complexity of performing an extended D2-lymphadenectomy. This surgical step can be facilitated by using robot-assisted surgery. The aim of this study is to describe our technique and short-term results of a consecutive series of full robotic gastrectomies with D2-lymphadenectomy for gastric cancer, using the da Vinci Surgical System. MATERIALS AND METHODS Between May 2004 and December 2009, we performed 24 consecutive full robot-assisted total and subtotal gastrectomies with extended D2-lymphadenectomy for histologically-proven gastric adenocarcinoma. Data referring to 11 robot-assisted total gastrectomies and 13 subtotal gastrectomies were collected in a database and analyzed. RESULTS Median operative time was 267.50 min (255-305). Median intraoperative blood loss was 30 mL. Median number of harvested lymph nodes was 28 (23-34). Resection margins were negative in all cases. No conversions occurred. Surgery-related morbidity was 8%. Thirty-day mortality was 0%. Liquid diet started on postoperative d 5 (2-5). Median length of stay was 6 d (5-8). CONCLUSIONS Robot-assisted gastrectomy with D2-lymphadenectomy is a safe technique and allows achieving an adequate lymph node harvest and optimal R0-resection rates with low postoperative morbidity and the learning curve appears to be shorter than in laparoscopic surgery. Longer follow-up and randomized clinical trials are needed to define the role of robot-assistance in gastric cancer surgery.

Abstract
BACKGROUND There may be large differences between measurements of end-tidal carbon dioxide partial pressure (Petco(2)) and arterial carbon dioxide partial pressure (Paco(2)) during laparoscopic surgeries. Transcutaneous carbon dioxide (Ptcco(2)) monitoring can be used to noninvasively and continuously estimate Paco(2). In the present study we evaluated the accuracy of Ptcco(2) monitoring in predicting the Paco(2) during laparoscopic surgeries with prolonged pneumoperitoneum. METHODS Sixteen patients who underwent laparoscopic radical gastrectomy or radical proctectomy under general anesthesia were included in the study. Their Paco(2), Petco(2), and Ptcco(2) values were measured at 3 time points before and after pneumoperitoneum. Agreement among measures was assessed by the Bland-Altman method. RESULTS Forty-eight sample sets were obtained. The average Paco(2)- Ptcco(2) difference was -0.9 + or - 6.4 mm Hg (mean + or - 2 SD). The average Paco(2) - Petco(2) difference was 7.5 + or - 7.0 mm Hg (mean + or - 2 SD). Paco(2) - Ptcco(2) was less than or equal to + or -5 mm Hg for 88% of the samples. Paco(2) - Petco(2) was less than or equal to + or -5 mm Hg for 17% of the samples (P < 0.05). CONCLUSIONS While undergoing long-term pneumoperitoneum laparoscopic surgery, Ptcco(2) monitoring is more accurate than is PETCO(2) monitoring in predicting the patients' Paco(2).

Abstract
BACKGROUND Laparoscopic total gastrectomy (LTG) has not gained widespread acceptance because of technical difficulties, especially esophagojejunal anastomosis. Various modified procedures for reconstruction have been reported, but an optimal method has not been established. The authors report a circular-stapled anastomosis using hand-sewn purse-string sutures, which is a simple and classic method. However, no previous study has assessed its reliability. METHODS From September 2008 to May 2009, 10 consecutive patients (9 men and 1 woman) with gastric cancer underwent LTG at the authors' institution. These patients had a median age of 63.7 years (range, 45-80 years) and a body mass index of 22.4 kg/m(2) (range, 18-26 kg/m(2)). After transection of the abdominal esophagus, a hand-sewn purse-string suture along the cut end of the esophagus was performed using 3-0 monofilament thread. An anvil head then was inserted into the esophagus, and the thread was tied. A monofilament pretied loop suture was added to reinforce the ligation. After the creation of an Roux-en-Y jejunal limb, laparoscopic esophagojejunal anastomosis was performed using a circular stapler inserted via a surgical glove attached to a wound retractor at the incision point at the umbilicus. The jejunal stump was closed with an endoscopic linear stapler. RESULTS Laparoscopic esophagojejunostomy was performed successfully for all the patients. No postoperative complications related to anastomosis occurred. In one patient, an intraabdominal abscess developed postoperatively and was treated conservatively. The mean operation time was 257 min, and the estimated blood loss was 69 ml. CONCLUSIONS With the described method, esophagojejunostomy can be performed as in conventional open surgery. Hand-sewn purse-string suturing is demanding technically, but it can be performed safely by experienced laparoscopic surgeons. This technique is feasible and can lower the cost of the laparoscopic procedure. It may be considered in countries with limited access to other special devices.

Abstract
BACKGROUND Single incision laparoscopic surgery (SILS) may further reduce the trauma of surgery leading to reduced port site complications and postoperative pain. The improved cosmetic result also may lead to improved patient satisfaction with surgery. METHODS Data were prospectively collected and retrospectively analyzed for all patients who underwent SILS appendicectomy at our institution and were compared with those who had undergone conventional laparoscopic appendicectomy during the same time period. This included patient demographic data, intraoperative, and postoperative outcomes. RESULTS Thirty-three patients underwent conventional laparoscopic appendicectomy and 40 patients underwent SILS appendicectomy between January 26, 2008 and July 14, 2009. Operative time was shorter with SILS appendicectomy compared with conventional laparoscopic appendicectomy (p < 0.05). No patients in the SILS appendicectomy group required conversion to open surgery compared with two patients in the conventional laparoscopic appendicectomy group. Patients stayed an average of 1.36 days after SILS appendicectomy, and 2.36 days after conventional laparoscopic appendicectomy. DISCUSSION SILS appendicectomy seems to be a safe and efficacious technique. Further work in the form of randomized studies is required to investigate any significant advantages of this new and attractive technique.

Abstract
Surgical resection remains the mainstay of treatment for gastric cancer. Laparoscopic assisted gastrectomy has failed to gain universal acceptance as an alternative to the open approach for a number of reasons, one of which includes the issue of oncological radicality in terms of lymph node dissection. Nodal status, which is one of the most crucial and independent predictors of patient survival, therefore has been examined both in single institutional trials and also in randomised controlled trials especially on early gastric cancer. The issue of oncological adequacy for laparoscopic lymph node harvesting for advanced gastric cancer remains a contentious issue because of the unique challenges it poses in terms of complexity, safety and time, and also the lack of randomised controlled trials in this area. It is thus imperative that good quality multicentre randomised controlled trials are designed to investigate the benefits of extended lymphadenectomy in the setting of laparoscopic surgery, especially for advanced gastric cancer and its impact on both short and long term survival.

Abstract
AIM: To compare the laparoscopic and the open gastrectomy approaches for short term morbidity, length of hospital stay and also long term gastrointestinal symptoms.
METHODS: Patients who have undergone gastrectomy had their medical records reviewed for demographic data, type of gastrectomy, short term morbidity, and length of hospital stay. Patients were contacted and asked to complete the Gastrointestinal Symptom Rating Scale (GSRS). The GSRS measures three domains of GI symptoms: Dyspepsia Syndrome (DS) for the foregut (best score 0, worse score 15), indigestion syndrome (IS) for the midgut (best score 0, worse score 12), and bowel dysfunction syndrome (BDS) for the hindgut (best score 0, worse score 16). Statistical analysis was done using the Mann-Whitney U-test.
RESULTS: We had complete data on 32 patients: 7 laparoscopic and 25 open. Of these, 25 had a gastroenteric anastomosis and 6 did not. The table shows the results as medians with interquartile range. Laparoscopic gastrectomy had a better score than open gastrectomy in the DS domain (0 vs 1, P = 0.02), while gastrectomy without anastomosis had a better score than gastrectomy with anastomosis in the IS domain (0 vs 1, P = 0.05).
CONCLUSION: Patients have little adverse gastrointestinal symptoms and preserve good gastrointestinal function after undergoing any type of gastrectomy. Laparoscopic approach had better dyspepsia and foregut symptoms. Performing an anastomosis led to mild adverse midgut and indigestion effects

Abstract
BACKGROUND In recent decade, laparoscopy-assisted distal gastrectomy (LADG) has been introduced to treatment of early gastric cancer (EGC). Previous meta-analyses included the randomized controlled trial (RCT) apparently contaminated with advanced gastric cancer. Besides, more RCTs enrolling the predictive EGC are available. The present meta-analysis was aimed to compare LADG with open distal gastrectomy (ODG) by updating the literature search and repooling the RCTs of only predictive EGC with improved methodology. METHODS Comprehensive search of PubMed, EmBase, and multiple websites of clinical trials registration and oncologic groups were performed. Only short-term outcomes measures were considered to meta-analysis. The RevMan 5.0 was used for pooled estimates. RESULTS Six RCTs of 629 patients totally were included for meta-analysis. Comparing LADG to ODG, results found less postoperative early morbidity (risk ratios=0.61, P=0.01), similar mortality (risk difference=0.01, P=0.32), prolonged operation time [mean difference (MD)=86.64 min, P<0.00001], decreased intraoperative blood loss (MD=-108.33 mL, P=0.001), decreased number of harvested lymph nodes (MD=-4.88, P<0.00001), forwarded time to oral intake (MD=-0.48 d, P=0.32), and shortened hospital stay (MD=-2.03 d, P=0.14). CONCLUSIONS LADG could bring the patients with EGC slight benefits by decreasing intraoperative blood loss and postoperative early morbidity, but unfavorably, might increase the operation time and decease the number of harvested lymph nodes. The long-term survival benefit is still eager to be proven by further outcomes of RCTs.
