Abstract
The goal of a gastric cancer operation is a microscopically negative resection margin and D2 lymphadenectomy. Minimally invasive techniques (laparoscopic and robotic) have been proven to be equivalent for oncologic care, yet with faster recovery. Endoscopic mucosal resection can be used for T1a N0 tumor resection. Better understanding of hereditary gastric cancer and molecular subtypes has led to specialized recommendations for MSI-high tumors and patients with pathogenic CDH1 mutations. In the future, surgical management will support minimally invasive approaches and personalized cancer care based on subtype.

Abstract
BACKGROUND Gastric cancer is one of the most common malignant tumors in the digestive system in China. Few comprehensive practice guidelines for early gastric cancer in China are currently available. Therefore, we created the Chinese national clinical practice guideline for the prevention, diagnosis, and treatment of early gastric cancer. METHODS This clinical practice guideline (CPG) was developed in accordance with the World Health Organization's recommended process and with the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) in assessing evidence quality. We used the Evidence to Decision framework to formulate clinical recommendations to minimize bias and increase transparency in the CPG development process. We used the Reporting Items for practice Guidelines in HealThcare (RIGHT) statement and the Appraisal of Guidelines for Research and Evaluation II (AGREE II) as reporting and conduct guidelines to ensure completeness and transparency of the CPG. RESULTS This CPG contains 40 recommendations regarding the prevention, screening, diagnosis, treatment, and follow-up of early gastric cancer based on available clinical studies and guidelines. We provide recommendations for the timing of Helicobacter pylori eradication, screening populations for early gastric cancer, indications for endoscopic resection and surgical gastrectomy, follow-up interval after treatment, and other recommendations. CONCLUSIONS This CPG can lead to optimum care for patients and populations by providing up-to-date medical information. We intend this CPG for widespread adoption to increase the standard of prevention, screening, diagnosis, treatment, and follow-up of early gastric cancer; thereby, contributing to improving national health care and patient quality of life.

Abstract
BACKGROUND To investigate the short-term and long-term outcomes of preserving the celiac branch of the vagus nerve during laparoscopic distal gastrectomy. METHODS A total of 149 patients with prospective diagnosis of gastric cancer who underwent laparoscopic-assisted distal gastrectomy (LADG) combined with Billroth-II anastomosis and D2 lymph node dissection between 2017 and 2018 were retrospectively analyzed. The patients were divided into the preserved LADG group (P-LADG, n = 56) and the resected LADG group (R-LADG, n = 93) according to whether the vagus nerve celiac branch was preserved. We selected 56 patients (P-LADG, n = 56) with preservation of the celiac branch of the vagus nerve and 56 patients (R-LADG, n = 56) with removal of the celiac branch of the vagus nerve by propensity-matched score method. Postoperative nutritional status, weight change, short-term and long-term postoperative complications, and gallstone formation were evaluated in both groups at 5 years of postoperative follow-up. The status of residual gastritis and bile reflux was assessed endoscopically at 12 months postoperatively. RESULTS The incidence of diarrhea at 5 years postoperatively was lower in the P-LADG group than in the R-LADG group (p < 0.05). In the multivariate logistic analysis, the removal of vagus nerve celiac branch was an independent risk factor for the occurrence of postoperative diarrhea (odds ratio = 3.389, 95% confidential interval = 1.143-10.049, p = 0.028). In the multivariate logistic analysis, the removal of vagus nerve celiac branch was an independent risk factor for the occurrence of postoperative diarrhea (odds ratio = 4.371, 95% confidential interval = 1.418-13.479, p = 0.010). CONCLUSIONS Preservation of the celiac branch of the vagus nerve in LADG reduced the incidence of postoperative diarrhea postoperatively in gastric cancer. TRIAL REGISTRATION This study was registered with the Ethics Committee of the First Affiliated Hospital of Dalian Medical University in 2014 under the registration number: LCKY2014-04(X).

Abstract
BACKGROUND A previous report confirmed the safety of laparoscopy-assisted total and proximal gastrectomies (LATG and LAPG) (JCOG1401). This report demonstrates the 5-year relapse-free survival (RFS) and overall survival (OS) after long-term follow-up to confirm the efficacy of these surgical methods as key secondary endpoints for cStage I gastric cancer. METHODS This study enrolled patients who had histologically proven gastric adenocarcinoma and were diagnosed with clinical T1N0, T1N(+), or T2N0 tumors according to the 14th edition of the Japanese Classification of Gastric Carcinoma (3rd English edition). RESULTS Between April 2015 and February 2017, 246 patients were enrolled, although one patient was excluded because of misregistration. Meticulous follow-up was continued for > 5 years for each patient, and the data were analyzed in March 2022. The 5-year RFS was 90.0% (95% confidence interval [CI] 85.5-93.2%), and the 5-year OS was 91.2% (95% CI 86.9-94.2%) in all enrolled patients. Grade 3 or 4 late postoperative complications were detected in 12.7% of patients. CONCLUSIONS This single-arm study showed that the long-term outcomes of LATG/LAPG for cStage I gastric cancer were acceptable, which is considered one of the standard treatments when performed by experienced surgeons.

Abstract
Background: Cardiopulmonary complications and liver dysfunction are also specific complications and problems associated with laparoscopic surgery. The main causes of postoperative liver dysfunction, which may often occur after laparoscopic surgery, include carbon dioxide pneumoperitoneum and ligation of the aberrant left hepatic artery. Hepatic steatosis may develop as a natural consequence of neoadjuvant therapy, although rarely, owing to chemotherapy. Nathanson retractor may cause a prolonged elevation in liver enzymes of these patients compared with those who do not receive neoadjuvant therapy. Materials and Methods: The data of 151 patients who underwent laparoscopic radical gastrectomy between January 2017 and January 2022 for histologically proven primary gastric cancer in our clinic were retrospectively reviewed. Results: The mean length of hospital stay was 6.21 days. The mean time normalization of the aspartate aminotransferase (AST) value was 2.45 ± 1.83 (range, 0-12) days postoperatively. The analysis of the correlation between the preoperative and postoperative 1-day values of alanine aminotransferase (ALT) and AST revealed a significant difference between the preoperative and postoperative 1-day median values of both parameters (P < .001). Each one unit increase in ALT led to an increase of 0.338 days in the length of intensive care stay and an increase of 0.345 days in the overall length of hospital stay. As the time to normalization of the AST value increased, the length of both intensive care stay and hospital stay increased. Each one unit increase in AST resulted in an increase of 0.316 days in the length of intensive care stay and an increase of 0.376 days in the overall length of hospital stay. Conclusion: Alternative retraction methods can be used safely in laparoscopic surgery for gastric cancer patients receiving neoadjuvant therapy. We are of the opinion that the Nathanson retractor should be used only during dissection of the relevant regions to shorten the intraoperative intermittent release or the time of use.

Abstract
The use of the robotic platform for gastrointestinal surgery was introduced nearly 20 years ago. However, significant growth and advancement has occurred primarily in the last decade. This is due to several advantages over traditional laparoscopic surgery allowing for more complex dissections and reconstructions. Several randomized controlled trials and retrospective reviews have demonstrated equivalent oncologic outcomes compared to open surgery with improved short-term outcomes. Unfortunately, there are currently no universally accepted or implemented training programs for robotic surgery and robotic surgery experience varies greatly. Additionally, several limitations to the robotic platform exist resulting in a distinct learning curve associated with various procedures. Therefore, implementation of robotic surgery requires a multidisciplinary team approach with commitment and investment from clinical faculty, operating room staff and hospital administrators. Additionally, there is a need for wider distribution of educational modules to train more surgeons and reduce the associated learning curve. This article will focus on the implementation of the robotic platform for surgery of the pancreas, stomach, liver, colon and rectum with an emphasis on the associated learning curve, educational platforms to develop proficiency and perioperative outcomes.

Abstract
Since Theodore Billroth and Cesar Roux perfected the methods of post-gastrectomy reconstruction in the late 19th century, surgical management of gastric and gastroesophageal cancer has made incremental progress. The majority of patients with localized disease are treated with perioperative combination chemotherapy or neoadjuvant chemoradiation. Staging laparoscopy before initiation of treatment or before surgical resection has improved staging accuracy and can drastically inform treatment decisions. The longstanding and contentious debate on the optimal extent of lymph node dissection for gastric cancer appears to have settled in favor of D2 dissection with the recently published 15-year follow-up of the Dutch randomized trial. Minimally invasive gastric and gastroesophageal resections are performed routinely in most centers affording faster recovery and equivalent oncologic outcomes. Pylorus-preserving distal (central) gastrectomy has emerged as a less invasive, function-preserving option for T1N0 middle-third gastric cancers, while randomized data on its oncologic adequacy are pending. Multi-visceral resections and cytoreductive surgery with hyperthermic intraperitoneal chemotherapy has been utilized selectively for patients with locally advanced tumors who have demonstrated disease control on preoperative chemotherapy. This review summarizes the current standard of surgical care for gastroesophageal junction and gastric cancer as well as highlights recent and upcoming advances to the field.

Abstract
PURPOSE Epidural analgesia (EDA) is an imperative modality for postoperative pain relief after major open abdominal surgery. However, whether EDA has benefits in laparoscopic surgery has not been clear. In this study, the effects of EDA and patient-controlled intravenous analgesia (PCIA) after laparoscopic distal gastrectomy (LDG) were compared. METHODS This was a retrospective study that included 82 patients undergoing LDG for gastric cancer. Patients received either EDA (n=67) or PCIA (n=15) for postoperative pain relief. Postoperative outcomes and analgesia-related adverse events were compared between the two modalities. RESULTS EDA and PCIA patients showed no differences in the incidence of complications [9 (13%) vs. 2 (13%); P=0.99] and the length of postoperative hospital stay (9.6±4.5 d vs. 9.7±4.0 d; P=0.90), although the PCIA included poorer preoperative physical status (PS) patients. The number of additional doses of analgesics was higher in the EDA than in the PCIA (1.8±2.4 vs. 0.9±1.0; P=0.01), although postoperative pain scores were similar in the 2 groups. Though the time to first passage of flatus was shorter in the EDA (P<0.05), more EDA patients developed postoperative hypotension as an adverse event (P<0.01). The full mobilization day and the day of oral intake tolerance were not significantly different between the 2 groups after surgery. CONCLUSIONS After LDG, EDA may not be indispensable, while PCIA may be the optimal modality for providing safe and effective postoperative analgesia and recovery.

Abstract
BACKGROUND We aimed to improve the tumor localization system using radiofrequency identification (RFID) technology used during laparoscopic surgery for gastric and colorectal cancer. To this end, we developed a detection algorithm and designed improvement for the RFID clip. METHODS To evaluate the proposed system, a swine-based animal study was conducted, followed by experiments on porcine stomachs and colons using the EASIE-R simulator. The success rates of endoscopic clipping, detection time, and detection accuracy, which is the distance between the detection point and RFID tag, were measured. RESULTS Results of the in vivo swine animal study showed success in all three clippings and detections of the RFID clips. Results of the 60 RFID endoclip attempts using the EASIE-R simulator showed a total clipping success rate of 85.0% (n = 51/60; stomach, 83.3%, n = 25/30; colon, 86.7%, n = 26/30). The median detection times were 29.2 s for the stomach and 25.5 s for the colon. The median detection accuracy was 4.0 mm for the stomach and 4.5 mm for the colon. CONCLUSIONS We confirmed that the proposed RFID-based system showed improvements over the system of a previous study. This RFID-based system is effective at localizing gastric and colorectal tumors.

Abstract
The World Health Organization (WHO) has declared gastric carcinoma a global health concern and gastric cancer remains the third leading cause of cancer deaths worldwide. With the rising incidence of gastric cancer, a body of both retrospective and randomized data has emerged since the early 1990's evaluating the role of minimally invasive platforms in the management of gastric cancer. While Eastern studies have shown that the laparoscopic approach is safe and feasible for advanced gastric cancer in Eastern patients, it is not clear whether this is true for patients in the West. Differences in tumor biology, stage at presentation, institutional volume, and surgeon experience all may impact the efficacy and widespread utilization of minimally invasive approaches in regions where gastric cancer is less prevalent. The majority of studies have pointed to a number of improvements associated with minimally invasive approaches including decreased blood loss, shorter length of hospital stay, lower analgesic requirements, decreased minor complications, and faster recovery without any significant difference in overall or disease specific survival (DSS). The benefits associated with minimally invasive approaches and evidence supporting similar oncologic outcomes compared to the traditional open approach will hopefully expand the indications for minimally invasive surgery in the management of gastric cancer. In the United States, results following initial experiences with minimally invasive techniques, including robotic platforms, have revealed promising results. Well-established laparoscopic and robotic techniques are emerging, particularly from high volume United States institutions, which will hopefully pave the way for increased utilization of minimally invasive surgery for gastric cancer in the West.

Abstract
The incidence of gastric cancer is increasing in the United States, particularly for various subtypes as well as presenting in earlier states. Such changes have allowed various centers to increasingly offer less invasive approaches to the treatment of gastric cancer, namely laparoscopic and robotic techniques. Minimally invasive gastrectomy has been suggested to have similar oncology outcomes compared to open procedures. In the last two decades, large retrospective and a series of randomized trials evaluated the role of minimally invasive gastrectomy for early gastric cancer, distal gastrectomy, total gastrectomy and advanced gastric cancer. As the experience with emerging technologies such as robotic assisted gastrectomies increases, the indications for minimally invasive surgery will likely expand.

Partially covered self-expandable metallic stent for postoperative benign strictures associated with laparoscopy-assisted gastrectomy. Gastric Cancer 2016; 19:280-6. [PMID: 25503478 DOI: 10.1007/s10120-014-0450-3] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/24/2014] [Accepted: 11/24/2014] [Indexed: 02/07/2023]
Abstract
BACKGROUND A partially covered self-expandable metallic stent (PCSEMS) is of proven benefit in palliation of unresectable or inoperable malignant gastric outlet obstruction. However, its use in patients with benign anastomotic stricture after laparoscopy-assisted gastrectomy (LAG) is not well established. METHODS Patients who between May 2007 and June 2012 underwent PCSEMS placement for management of benign gastrointestinal obstruction after LAG were included in this retrospective analysis. The primary outcomes were the technical success and clinical success of the PCSEMS. The secondary outcomes were procedure-related complications and PCSEMS dysfunction. RESULTS Eleven patients (six women, five men, mean age 53.5 years, range 15-76 years) underwent successful placement of a PCSEMS for management of benign anastomotic strictures after LAG and were followed-up for a mean of 20.6 months (range 7.9-55.6 months). The mean gastric outlet obstruction scoring system (GOOSS) score was 0.36 before PCSEMS placement and 1.55 (p = 0.010) 24-48 h after PCSEMS placement. All of the patients were able to tolerate a solid diet (GOOSS score 3) after 1 week. There were no major or minor procedure-related complications. Stent dysfunction occurred in four patients (three distal migrations, one proximal migration), and stent removal was successful in all of the remaining patients after a mean of 2.0 months (1.1-3.0 months). Obstructive symptoms recurred in two patients (one after proximal migration, one after stent removal) and were treated successfully with PCSEMS reinsertion and balloon dilation. CONCLUSIONS A PCSEMS may be a feasible and effective option for management of benign anastomotic strictures after LAG which could avoid secondary surgery.

Abstract
Laparoscopic-assisted distal gastrectomy (LADG) with D2 resection is gradually being performed for treating advanced gastric cancer. This meta-analysis aims to compare the clinical outcomes between LADG and open distal gastrectomy (ODG) when considering the impact of the learning curve. The PubMed, Embase, and ISI databases and the Cochrane Library were electronically searched. Randomized controlled trails and retrospective comparative studies published between 1994 and 2013 were collected. We divided the included studies into two subgroups according to whether the authors had experience of at least or fewer than 40 cases of LADG with D2 resection and then compared the operative time, intraoperative bleeding, the amount of resected lymph nodes, short-term recovery parameters, and complications between LADG and ODG groups. Ten comparative studies including 1100 patients were selected. Meta-analysis showed that when LADG was compared with ODG, surgeons with experience of at least 40 cases could achieve more resected lymph nodes (P=.002), reduced time to flatus (P<.0001), shortened time to liquid diet (P<.00001), and lower complication rates (P=.02). However, the above advantages of LADG faded in the subgroup of surgeons with experience of fewer than 40 cases. Our meta-analysis suggested that the learning curve has significant effects on most of the important surgical and short-term recovery outcome parameters. Accomplishment of 40 cases of LADG with D2 lymphadenectomy is required to achieve optimum proficiency.

Abstract
PURPOSE The optimal analgesia following laparoscopic distal gastrectomy (LDG) has not been determined; moreover, it has been unclear whether epidural anesthesia has benefits for laparoscopic surgery. In this study, we evaluated the effectiveness of epidural analgesia after LDG. METHODS This retrospective study included 84 patients who underwent LDG for gastric cancer. Patients received either combined thoracic epidural and general anesthesia (Epidural group, n = 34) or general anesthesia alone (No epidural group, n = 50). We recorded data on the patients, surgery, postoperative outcomes and anesthesia-related complications. RESULTS In the Epidural group, the first day of flatus was significantly earlier (2.21 vs. 2.44 days, p = 0.045) and the number of additional doses of analgesics was significantly lower (2.85 vs. 4.86 doses, p = 0.007) than in the No epidural group. Postoperative urinary retention occurred at a significantly higher rate in the Epidural group (n = 7; 20.6 %) than in the No epidural group (p < 0.001). CONCLUSION Epidural anesthesia may reduce the need for additional analgesics after LDG, but increases the risk of urinary retention.

Abstract
BACKGROUND Pre-emptive intravenous lidocaine infusion is known to improve postoperative pain in abdominal surgery. We assessed the effect of intravenous lidocaine infusion in patients who underwent subtotal gastrectomy. METHODS We conducted a double-blind, placebo-controlled study with patients undergoing subtotal gastrectomy for early gastric cancer divided into 2 groups: 1 group received intravenous lidocaine infusion preoperatively and throughout surgery, and the other received normal saline infusion (placebo). We assessed postoperative outcomes, including pain scores on a visual analogue scale (VAS), administration frequency of patient-controlled analgesia (PCA) and the amount of consumed fentanyl. Postoperative nausea and vomiting, length of hospital stay (LOS), time to return to regular diet and patient satisfaction at discharge were evaluated. RESULTS There were 36 patients in our study. Demographic characteristics were similar between the groups. The VAS pain scores and administration frequency of PCA were significantly lower in the lidocaine group until 24 hours after surgery, and fentanyl consumption was significantly lower in this group until 12 hours postoperatively compared with the placebo group. The total amount of consumed fentanyl and the total administration frequency of PCA were significantly lower in the lidocaine than the control group. No significant differences were detected in terms of nausea and vomiting, return to regular diet, LOS and patient satisfaction, and there were no reported side-effects of lidocaine. CONCLUSION Intravenous lidocaine infusion reduces pain during the postoperative period after subtotal gastrectomy.

Abstract
BACKGROUND Laparoscopic distal gastrectomy has been increasingly utilized in the treatment of gastric adenocarcinoma. This study aims to compare the morbidity/mortality and postoperative outcomes of laparoscopic-assisted versus open distal gastrectomy since 2000. METHODS A comprehensive search of MEDLINE and EMBASE was conducted including studies published between 2000 and present. RESULTS Seventeen studies with a total of 7,109 distal gastrectomies (3,496 lap vs 3,613 open) were included. Across all studies, postoperative morbidity rates for laparoscopic gastrectomy were lower than that of open [median (range) 10 (0-36) % vs 17 (0-43) %]. Meta-analysis of postoperative morbidity rates in prospective studies only yielded pooled odds ratio of 0.52 (95 % CI 0.33-0.81) (P = 0.004). In-hospital mortality rates were comparable between the two (range: laparoscopic 0-3.3 vs open 0-6.7 %). The long-term oncological outcomes of resection were difficult to analyze given variable reporting but appeared similar between the two. Meta-analysis of prospective studies showed that laparoscopic-assisted distal gastrectomy was associated with significantly shorter hospital length of stay [standard mean difference (SMD) = -0.78 (95 % CI = -1.0 to -0.56)], comparable intraoperative bleeding [SMD = 0.64 (95 % CI = -1.3-0.0430) P = 0.066] and longer operative time compared to open gastrectomy [1.9 (95 % CI 0.05-3.8) P = 0.045, with P < 0.001]. CONCLUSION This study supports the use of laparoscopic-assisted distal gastrectomy for treatment of gastric adenocarcinoma with evidence of comparable, if not better, short-term postoperative parameters when compared to open distal gastrectomy. The long-term oncological outcomes appear similar but may require more evaluation.

Abstract
BACKGROUND Laparoscopy-assisted distal gastrectomy (LADG) is generally considered superior to open distal gastrectomy (ODG) with regard to postoperative quality-of-life. Differences in postoperative pain may exist due to recent pain control techniques including epidural anesthesia. There is little evidence for this difference. In this article we report the results of our randomized single-blind study in LADG versus ODG. The aim of the present study was to evaluate differences in postoperative physical activity between LADG and ODG. METHODS Forty patients with early gastric cancer (stage IA and IB) were registered in this randomized study. For strict evaluation, patients were not told about the type of operation until postoperative day 7. Postoperative physical activity was evaluated objectively by Active Tracer, which records the cumulative acceleration over a 24 h period to investigate differences in postoperative recovery. Questionnaire and visual analog scale score related to postoperative pain were also investigated. RESULTS Significant differences were observed with a more favorable outcome noted in the LADG group with respect to intraoperative blood loss (P < 0.001), total amount of pain rescue (P < 0.001), wound size (P < 0.001), postoperative hospital stay (P < 0.001), and inflammatory parameters (C-reactive protein, SaO2, and duration of febrile period) (P < 0.001). Cumulative physical recovery to 70 % of the preoperative level was significantly shorter (by 3 days, P < 0.001) in the LADG group. CONCLUSIONS Comparison of LADG and ODG for patients with early gastric cancer showed favorable outcome and earlier recovery of physical activity in the LADG group.

Abstract
BACKGROUND Completion total gastrectomy for remnant gastric cancer (RGC) is technically challenging, especially using the minimally invasive approach. Only a few small case series have reported the technical feasibility of completion total gastrectomy by minimally invasive surgery (MIS). The aim of this study was to compare the efficacy and safety of MIS and open surgery for RGC. METHODS We retrospectively analyzed 76 completion total gastrectomies for RGC between 2005 and 2012. Indications for MIS were limited to no evidence of serosa invasion or lymph node metastasis to extraperigastric areas on preoperative evaluation. We compared patient characteristics, intraoperative factors, post-operative outcomes, and survival for the MIS and open surgery groups. RESULTS Eighteen patients underwent completion total gastrectomy with MIS (10 laparoscopic, 8 robotic) and 58 patients underwent open surgery. Operation time was longer in the MIS than the open group (266 vs. 203 min, P = 0.004), but the groups had similar estimated blood loss, frequency of unplanned other organ resection, and number of retrieved lymph nodes. The MIS group had a significantly earlier initiation of soft diet, shorter hospital stay, and fewer pain medication injections. Complication rates, recurrence, and overall 5-year survival were similar for the two groups. When we compared laparoscopy with robotic, similar result was shown in all parameters except operation time. CONCLUSIONS Compared to open surgery, MIS for RGC demonstrated better short-term outcome and comparable oncologic results. MIS for RGC is feasible and safe and maintains advantages of minimal invasiveness. Both laparoscopic and robotic approaches are reasonable to the management of RGC.

Abstract
PURPOSES In the current study, we evaluated the efficacy of dual-phase three-dimensional (3D) CT angiography (CTA) in the assessment of the vascular anatomy, especially the right hepatic artery (RHA), before gastrectomy. METHODS The study initially included 714 consecutive patients being treated for gastric cancer. A dual-phase contrast-enhanced CT scan using 32-multi detector-row CT was performed for all patients. RESULTS Among the 714 patients, 3D CTA clearly identified anomalies with the RHA arising from the superior mesenteric artery (SMA) in 49 cases (6.9 %). In Michels' classification type IX, the common hepatic artery (CHA) originates only from the SMA. Such cases exhibit defective anatomy for the CHA in conjunction with the celiac-splenic artery system, resulting in direct exposure of the portal vein beneath the #8a lymph node station, which was retrospectively confirmed by video in laparoscopic gastrectomy cases. Fused images of both 3D angiography and venography were obtained, and could have predicted the risk preoperatively, and the surgical finding confirmed its usefulness. CONCLUSION Preoperative evaluations using 3D CTA can provide more accurate information about the vessel anatomy. The fused images from 3D CTA have the potential to reduce the intraoperative risks for injuries to critical vessel, such as the portal vein, during gastrectomy.

Abstract
PURPOSE Laparoscopy-assisted distal gastrectomy for early gastric cancer has gained acceptance and popularity worldwide. However, laparoscopy-assisted distal gastrectomy for advanced gastric cancer is still controversial. Therefore, we propose this prospective randomized controlled multi-center trial in order to evaluate the safety and feasibility of laparoscopy assisted D2-gastrectomy for advanced stage gastric cancer. MATERIALS AND METHODS Patients undergoing distal gastrectomy for advanced gastric cancer staged cT2/3/4 cN0/1/2/3a cM0 by endoscopy and computed tomography are eligible for enrollment after giving their informed consent. Patients will be randomized either to laparoscopy-assisted distal gastrectomy or open distal gastrectomy. Sample size calculation revealed that 102 patients are to be included per treatment arm. The primary endpoint is the non-compliance rate of D2 dissection; relevant secondary endpoints are three-year disease free survival, surgical and postoperative complications, hospital stay and unanimity rate of D2 dissection evaluated by reviewing the intraoperative video documentation. DISCUSSION Oncologic safety is the major concern regarding laparoscopy-assisted distal gastrectomy for advanced gastric cancer. Therefore, the non-compliance rate of clearing the N2 area was chosen as the most important parameter for the technical feasibility of the laparoscopic procedure. Furthermore, surgical quality will be carefully reviewed, that is, three independent experts will review the video records and score with a check list. For a long-term result, disease free survival is considered a secondary endpoint for this trial. This study will offer promising evidence of the feasibility and safety of Laparoscopy-assisted distal gastrectomy for advanced gastric cancer.

Abstract
BACKGROUND AND OBJECTIVE Laparoscopic gastrectomy (LG) for gastric cancer has been adopted to treat both early and locally advanced gastric cancer (AGC), but there are still concerns about its oncologic safety especially in AGC. The purpose of this meta-analysis is to compare the long-term outcomes of LG with those of open gastrectomy (OG) in patients with AGC. METHODS The quantitative synthesis of outcomes of studies from three major databases, PubMed, Embase, and the Cochrane Central, was performed using common keywords related to gastric cancer and laparoscopy on July 31, 2012. RESULTS Ten studies (one randomized controlled trial and nine retrospective cohort studies) with 1,819 participants (960 patients in OG, and 859 patients in LG) were included in the current meta-analysis. Nine studies compared the overall survival rate between LG and OG for AGC, and five studies reported the disease-free survival. There was no statistical difference in overall survival (hazard ratio [HR]: 0.90, 95% confidence interval [CI]: 0.76-1.06, P = 0.22) and disease-free survival (HR: 1.03, 95% CI: 0.76-1.40, P = 0.86) between the two modalities. CONCLUSIONS The current clinical evidence revealed that there was no evidence that LG is inferior to OG even for AGC if the surgeons have sufficient experience.

Abstract
Background Traditional open surgery for gastrointestinal stromal tumors (GIST) requires a long incision. Moreover, the gas-filling laparoscopic technique used in GIST surgery still has its limitations. Therefore, we developed a gasless laparoscopic (GL) surgery for GIST and compared it with traditional open surgery. Methods Between October 2007 and September 2009, 62 GIST patients in the National Taiwan University Hospital received wide excisions. Of these 62 patients, 30 underwent the new procedure (GL group) and 32 had open surgery (OS group). Preoperative and postoperative clinicopathologic characteristics were compared between the groups. Results There were no significant differences in preoperative characteristics or blood loss. However, the days to first flatus, postoperative hospital stay, wound length, white blood cell count at postoperative day one, and peak daily body temperature were all significantly improved in the GL group. Usage of postoperative analgesia on postoperative days one to five was also significantly lower in the GL group. Conclusions Wide-excision laparoscopy for gastric GIST can be performed more safely, more effectively, and with faster postoperative recovery using the gasless technique as compared with the open method. We, therefore, recommend this new surgical technique, which hybridizes the advantages of both the traditional open method and pure laparoscopic surgery.

Abstract
BACKGROUND Laparoscopy-assisted gastrectomy (LG) is an established treatment for early gastric cancer. However, carbon dioxide pneumoperitoneum during laparoscopic surgery can adversely affect the pulmonary function of patients with chronic obstructive pulmonary disease (COPD). This retrospective cohort study was performed to assess the feasibility of LG for patients with COPD. METHODS Among 1,053 patients who underwent radical gastrectomy with lymph node dissection between 1999 and 2011 at the authors' hospital, 220 patients with COPD were studied retrospectively. The clinical outcomes for the patients with COPD who underwent LG (LG group) were compared with those of COPD patients who underwent open gastrectomy (OG group), as well as those of patients with no operative risk and normal pulmonary function who underwent LG (NOR group). Postoperative pulmonary complications (PPCs) were defined as pneumonia, atelectasis, pneumothorax, prolonged mechanical ventilation (>24 h), and adult respiratory distress syndrome within 30 days after operation. RESULTS Pulmonary function variables were similar in the LG and OG groups. The findings showed PPCs to be slightly but not significantly less frequent in the LG group (1.7 %) than in the OG group (6.3 %) (p = 0.09). No difference in PPCs was found between the LG group and the NOR group (p > 0.99). For patients with COPD, advanced stage (stage 2 or 3 vs stage 1) was significantly associated with PPCs (p = 0.03), but was not an independent risk factor for PPCs (p = 0.12). CONCLUSION The LG procedure is tolerated in patients with gastric cancer who have mild or moderate COPD, similar to OG.

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 The aims of this study were to investigate trends in minimally invasive surgery (MIS) for gastric cancer through the experience of a single center and to predict the direction of the development of MIS. METHODS During a 7-year period, 2,160 patients underwent curative gastric cancer surgery. Changes in the proportion and pathologic features of a total of 750 cases that involved MIS, as well as the surgical methods and outcomes of MIS, were analyzed. RESULTS An analysis of the patient population treated by MIS revealed that the proportion of patients with T2 or greater tumors on the basis of pathologic findings was initially <5.0% but had recently increased to 24.3%. Although the proportions of intracorporeal anastomosis and robotic surgery had recently increased, the complication rate and operative time had stabilized 2 years after the 1st MIS. CONCLUSIONS Given these results, the application of MIS for gastric cancer is expected to become more frequent. In addition, new modalities will be preferred by both surgeons and patients to reduce the invasiveness of gastric cancer surgery.

Quality of life beyond the early postoperative period after laparoscopy-assisted distal gastrectomy: the level of patient expectation as the essence of quality of life. Gastric Cancer 2012; 15:299-304.

Abstract
BACKGROUND The aim of this study was to compare the quality of life after the early postoperative period and before reaching 5 years postoperatively between patients who underwent laparoscopy-assisted distal gastrectomy (Group A) and patients who underwent open distal subtotal gastrectomy (Group B). METHODS The Korean versions of the European Organization for Research and Treatment (EORTC) Quality of Life Questionnaire Core 30 (QLQ-C30) and a gastric cancer-specific module, the EORTC QLQ-STO22, were used to assess the quality of life of 80 patients who underwent laparoscopy-assisted distal gastrectomy or open distal subtotal gastrectomy for gastric cancer. The postoperative period ranged between 6 months and 5 years. RESULTS The global health status/quality of life scores of Groups A and B were 56.0 ± 19.0 and 57.4 ± 18.2, respectively (p = 0.729). Group A experienced worse quality of life in role functioning (p = 0.026), cognitive functioning (p = 0.034), fatigue (p = 0.039), eating restrictions (p = 0.009), and anxiety (p = 0.033). Group A showed a trend to experience worse quality of life in physical functioning, emotional functioning, social functioning, insomnia, and body image, albeit without statistical significance. CONCLUSION After the early postoperative period and before achieving long-term survival, patients who underwent laparoscopy-assisted distal gastrectomy appeared to experience lower quality of life compared to patients who underwent open distal subtotal gastrectomy. This finding may be associated with the patients' erroneously high expectations of laparoscopy-assisted distal gastrectomy.

Abstract
BACKGROUND We performed a meta-analysis in an attempt to answer whether short-term outcomes and lymph nodes harvested after laparoscopy-assisted gastrectomy (LAG) are comparable to those reported after conventional open gastrectomy (COG). METHODS Prospective randomized clinical trials were eligible if they included patients with distal gastric cancer treated by LAG versus COG. End points were operating time, intra-operative blood loss, size of wound, overall post-operative complications, time to first flatus, time to start oral intake, hospital stay and lymph nodes harvested. RESULTS Six trials including 668 patients were included. For four of the 13 end points, the summary point estimates favoured LAG over COG; there was a significant reduction in intra-operative blood loss (weighted mean difference (WMD) −115.60, 95% confidence interval (CI) −159.16 to −72.04, P < 0.00001), size of wound (WMD −5.27, 95% CI −8.94 to −1.60, P= 0.005), overall post-operative complications (odds ratio 0.55, 95% CI 0.35 to 0.85, P = 0.008) and hospital stay (WMD −2.65, 95% CI −4.97 to −0.32, P= 0.03) for LAG. However, the combined results of the individual trials show significant longer operating time (WMD 112.98, 95% CI 60.32 to 165.64, P < 0.0001) and significant reduction in lymph nodes harvested (WMD −4.79, 95% CI −6.79 to −2.79, P < 0.00001) in the LAG group. There was no significant difference between the two groups in time to first flatus, time to start oral intake, wound infection, intra-abdominal fluid collection and abscess, anastomotic stenosis and leakage and pulmonary complications. CONCLUSION The results of this meta-analysis suggest that LAG for early distal cancer is a feasible and safe alternative to COG, with better short-term outcomes.

Abstract
OBJECTIVE To perform a meta-analysis of high-quality published trials, randomized and observational, comparing laparoscopic distal gastrectomy (LDG) and open distal gastrectomy (ODG) for gastric cancer. BACKGROUND Controversy persists about the clinical utility of minimally invasive techniques for the treatment of gastric cancer. Prospective data is limited to a few small randomized trails. METHODS : Studies published from January 1992 to March 2010 that compare LDG and ODG were identified. No restrictions in pathologic stage were applied. All randomized controlled trials (RCTs) were included. Selection of high-quality, nonrandomized comparative studies (NRCTs) was based on a validated tool (Methodological Index for Nonrandomized Studies). Mortality, complications, harvested lymph nodes, operative time, blood loss, and hospital stay were compared using weighted mean differences (WMDs) and odds ratios (ORs). RESULTS Twenty-five studies were included in the analyses, 6 RCTs and 19 NRCTs, compromising 3055 patients (1658 LDG, 1397 ODG). LDG was associated with longer operative times (WMD 48.3 minutes; P < 0.001) and lower overall complications (OR 0.59; P < 0.001), medical complications (OR 0.49; P = 0.002), minor surgical complications (OR 0.62; P = 0.001), estimated blood loss (WMD -118.9 mL; P < 0.001), and hospital stay (WMD -3.6 days; P < 0.001). Mortality and major complications were similar. Patients in the ODG group had a significantly higher number of lymph nodes harvested (WMD 3.9 nodes; P < 0.001), although the estimated proportion of patients with less than 15 retrieved nodes was similar (OR 1.26, P = 0.09). CONCLUSIONS LDG can be performed safely with a shorter hospital stay and fewer complications than open surgery. The long-term significance of a difference of less than 5 nodes in the number of harvested lymph nodes remains unclear. Lymph node staging appears to be unaffected. These results need to be validated in Western patients with advanced gastric cancer.

Abstract
There has been much speculation regarding differences in outcome for patients who have gastric cancer in the Eastern versus Western world. Among other factors, these differences have contributed to a unique cohort of patients and experience in the Western staging/evaluation of gastric cancer and in the application of minimally invasive approaches for treatment. This review summarizes the current state of laparoscopic approaches for the staging and treatment of gastric adenocarcinoma for patients presenting in Western countries, with their associated unique presentation, comorbidities, and outcomes.

Abstract
BACKGROUND Randomized trials and cohort studies show that laparoscopic distal gastrectomy (LDG) achieves similar oncological results to open distal gastrectomy (ODG). However, studies have consistently demonstrated lower lymph node yield (LNY) for laparoscopic lymphadenectomy. Analysis of station-specific LNY may be useful in evaluating the reasons behind this difference. OBJECTIVES Comparison of station-specific LNY, surgical, and oncological outcomes between LDG and ODG for early gastric cancer. METHODS Patients who underwent R0 distal gastrectomy with histologically confirmed early gastric cancer were eligible for the study. All consecutive cases of LDG since the beginning of our experience with laparoscopic gastrectomy and synchronous cases of ODG with R0 resection were included in the study. Demographic, operative, histopathologic, and follow-up data were recorded in all patients. RESULTS A total of 259 cases of LDG and 95 cases of ODG were performed between 2000 and 2009. Patients undergoing LDG had longer operations but less bleeding (P<0.05). Postoperative complications were similar in both groups. The preoperatively planned extent of lymphadenectomy was D1 (stations 1, 3, 4sb, 4d, 5, 6, and 7), D1+ (D1with stations 8a and 9), or D2 (D1+ with stations 11p and 12a). During surgery, dissection of stations 3, 4d, 5, 6, and 7 was performed in all cases of LDG and ODG. Dissection of stations 1, 4sb, 8a, 9, 11p, and 12a was performed more frequently during ODG than during LDG. Consequently, the total LNY was 26.71 and 31.43 for LDG and ODG, respectively. Station-specific LNY was significantly lower for LDG than for ODG in the common hepatic artery nodes only (P<0.05). The mean follow-up was 43.6 months. Lymph node metastases, metastatic-to-resected lymph node ratio, recurrence, and cancer-related deaths were similar for LDG and ODG. CONCLUSIONS LDG was associated with less extensive lymph node dissection compared with ODG. Station-specific LNY was similar in all nodal stations except for the common hepatic artery nodes. In our experience, laparoscopic sub-D2 lymphadenectomy was adequate in the context of early gastric cancer and represents the future of gastric cancer resection in Japan.

Abstract
BACKGROUND Laparoscopy-assisted gastrectomy (LAG) is becoming widely used for early gastric cancer. However, how the curability and long-term prognosis of LAG and open gastrectomy (OG) for early and advanced gastric cancer compare remains unclear. This study assessed short- and long-term outcomes after LAG with lymph node dissection in early and advanced gastric cancer. METHODS A total of 332 patients who underwent LAG or OG for early and advanced gastric cancer from January 2001 through December 2010 were reviewed retrospectively. The mean operating time, estimated mean blood loss, number of dissected lymph nodes, and survival rates were compared between LAG and OG for early and advanced gastric cancer. RESULTS Overall, 47.6% (158/332) of patients underwent LAG; D1, D1+ lymph node dissection was carried out in 77.2%, with D2 dissection in 22.8%. Only one patient required conversion to OG. Comparing LAG and OG with D1, D1+ lymph node dissection for early gastric cancer (EGC), mean operating time was significantly longer, estimated mean blood loss was significantly smaller, and the average number of retrieved lymph nodes was significantly greater with LAG. The rate of specific postoperative morbidity was 17.2% for LAG patients and 25.0% for OG patients, with no postoperative mortality. Survival and recurrence rates were not significantly different. Comparing LAG and OG with D2 lymph node dissection for advanced gastric cancer (AGC), mean operating time was significantly longer and estimated mean blood loss was significantly smaller with LAG, while the average number of retrieved lymph nodes, specific postoperative morbidity and mortality, and survival and recurrence rates were not significantly different. CONCLUSIONS LAG with D1, D1+ lymph node dissection for EGC is safe and equivalent to open gastrectomy in curability. Moreover, LAG with D2 lymph node dissection for AGC is comparable to OG with D2 lymph node dissection with regard to short- and long-term results.

Abstract
Laparoscopy-assisted distal gastrectomy for gastric cancer was first reported by Kitano et al. in 1991. Laparoscopic wedge resection (LWR) and intragastric mucosal resection (IGMR) were quickly adapted for gastric cancer limited to the mucosal layer and having no risk of lymph node metastasis. Following improvements in endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD), the use of LWR and IGMR for these indications decreased, and patients with gastric cancer, including those with a risk of lymph node metastases, were more likely to be managed with laparoscopic gastrectomy (LG) with lymph node dissection. Many retrospective comparative trials and randomized-controlled trials (RCT) have confirmed that LG is safe and feasible, and that short-term outcomes are better than those of open gastrectomy (OG) in patients with early gastric cancer (EGC). However, these trials did not include a satisfactory number of patients to establish clinical evidence. Thus, additional multicenter randomized-controlled trials are needed to delineate significantly quantifiable differences between LG and OG. As laparoscopic experience has accumulated, the indications for LG have been broadened to include older and overweight patients and those with advanced gastric cancer. Moreover, advanced techniques, such as laparoscopy-assisted total gastrectomy, laparoscopy-assisted proximal gastrectomy, laparoscopy-assisted pylorus-preserving gastrectomy (PPG), and extended lymph node dissection (D2) have been widely performed.In the near future, sentinel node navigation and robotic surgery will become additional options in minimally invasive surgery (MIS) involving LG. Such developments will improve the quality of life of patients following gastric cancer surgery.

Current literature suggests that minimally invasive distal gastrectomy (MIDG) may enhance post-operative recovery and decrease morbidity compared to open surgery (ODG) in patients with gastric cancer. A meta-analysis of six Prospective Randomized Trials comparing MIDG (343 patients) and ODG (323 patients) for gastric cancer was conducted. MIDG was associated with increased operative time, reduced blood loss and overall morbidity. There was not sufficient data to draw solid conclusions about the oncologic quality of MIDG.

Abstract
BACKGROUND Totally laparoscopic distal gastrectomy (TLDG) has several advantages over laparoscopic-assisted distal gastrectomy (LADG), including a shorter incision, less pain, and earlier recovery. We compared the feasibility and early surgical outcomes of TLDG and LADG in patients with gastric cancer. METHODS Between September 2008 and December 2009, 180 patients with gastric cancer underwent TLDG with intracorporeal gastroduodenostomy using linear staplers; and between January 2006 and December 2009, 268 patients with gastric cancer underwent LADG with extracorporeal gastroduodenostomy using circular staplers. Clinical features and early surgical outcomes were compared between the two groups. RESULTS There were no between-group differences in postoperative clinical course and complications. Postoperative pain and the amount of pain killer administered were significantly lower (P<.05 each), and postoperative scars were smaller in the TLDG group. CONCLUSIONS TLDG with intracorporeal gastroduodenostomy is as safe and feasible as LADG for patients with gastric cancer. Moreover, TLDG is less invasive and more comfortable for patients than LADG.

Laparoscopic versus open distal gastrectomy for locally advanced gastric cancer: a case-control study. Updates Surg 2011; 63:17-23.

Abstract
In a non-specialized setting, laparoscopic distal gastrectomy (LDG) for locally advanced diseases remains controversial, particularly given to the technical demands of the learning curve required to perform an adequate resection with D2 lymph node dissection. Inclusion criteria for this statistically generated matching controlled study were all patients who underwent subtotal laparoscopic gastrectomies from January 2006 until September 2009 for locally advanced gastric adenocarcinoma (stage II-IIIb), compared with matched patients who underwent the same procedure in an open fashion during the same period. Sixty case-matched patients were evaluated (30 laparoscopic vs. 30 open). Operative time was significantly longer (p < 0.05) for LDG. Benefits for LDG (p < 0.05) were observed among surgical short-term outcome (postoperative hospital stay, ambulation, first bowel movement, first flatus, first stool, first eating and use of analgesic drugs) and postoperative non-surgical site complications (cardiopulmonary, urinary, etc.). The 42 months' overall survival was similar (p = 0.646). Laparoscopic gastrectomy is a safe technique in a non-academic hospital setting for locally advanced gastric cancer; it seems to be adequate in terms of margin status and adequate lymph node retrieval and is associated with additional benefits as a decreased length of hospital stay, a decreased narcotic use and fewer complications.

Abstract
BACKGROUND Laproscopic surgery is widely used in treating gastrointestinal disease. This study investigated the clinical result, short-term outcomes, and cost analysis of the newly developed gasless laparoscopy-assisted distal gastrectomy (GLADG) and compared it with conventional open distal gastrectomy (ODG). METHODS Seventy-five patients underwent distal gastrectomy with radical lymph node dissection for early gastric cancer from December 2005 to January 2008. Thirty-one patients underwent GLADG and 44 underwent ODG. Postoperative pain, morphine use, disease-free and overall survival, and surgical and hospital costs were measured postoperatively and compared between the two groups. RESULTS Patients in the two groups were comparable by age, sex, body mass index, tumor size, tumor location, cancer staging, and operative time. The GLADG group had early start of oral intake and shorter postoperative hospital stay (P < .05). There was less morphine use from postoperative day 1 to 4 in the GLADG group than in the ODG group (P < .05), and body temperature from postoperative day 1 to 2 was lower in the GLADG than in the ODG group (P < .05). Cost analysis showed that operation cost (100,242 ± 5385 versus 36,455 ± 1419) and equipment cost (65,909 ± 5385 versus 2122 ± 1419) was higher in the GLADG group, but its total hospital cost (193,552 ± 12,715 versus 206,676 ± 41,920) was lower than in the ODG group (P < .05). The 2-year disease-free and overall survival rates were not different between the two groups. CONCLUSIONS GLADG is feasible for early gastric cancer. It is advantageous because of less pain, less postoperative inflammatory response, less blood loss, and shorter total hospital stay while achieving the same oncologic results as ODG.

Abstract
BACKGROUND Laparoscopic distal pancreatectomy (LDP) has been shown to be an effective surgical option for benign lesions in the body and tail of the pancreas. However, its advantages and disadvantages have not been well characterized. In this study, we compared the outcomes of LDP and open pancreatectomy performed in our clinic. MATERIALS AND METHODS Peri- and postoperative outcomes were retrospectively compared between patients with benign pancreatic disorders who underwent open distal pancreatectomy (ODP) (n = 35) and those who underwent LDP (n = 40). The peri- and postoperative factors analyzed included operative time, blood loss, hospital stay, postoperative recovery, biochemical findings, and complications. RESULTS LDP was associated with significantly less operative blood loss (363 versus 606 mL; P = 0.001) and shorter hospital stay (22 versus 27 day; P = 0.009), but longer operative time (342 versus 250 min; P = 0.000), compared with ODP. There were no significant differences between the two groups in complication rates or postoperative recovery, except for the significantly shorter duration of postoperative pain-killer intake and earlier improvement of the biochemical analysis in LDP than in ODP. CONCLUSIONS LDP appears to be a safe, desirable procedure for the management of benign pancreatic diseases, with outcomes similar to ODP.

Abstract
INTRODUCTION Laparoscopic gastrectomy is rapidly expanding despite reservations by some surgeons regarding its safety and radicality. The aim of this study was to evaluate patients undergoing laparoscopic gastrectomy for both benign and malignant disease with particular emphasis on technical feasibility, safety, effectiveness and complications. PATIENTS AND METHODS Review of prospectively collected data of patients who underwent laparoscopic gastrectomy from May 2005 to September 2009 under the care of one consultant surgeon. RESULTS A total of 61 laparoscopic gastrectomies were performed (35 men and 26 women) with a median age of 68 years (range, 41-90 years). There were 39 distal gastrectomies (19 adenocarcinoma, 6 gastrointestinal stromal tumour [GIST], 4 benign gastric outlet obstruction, 4 high-grade dysplasia in gastric adenomas, 4 non-healing ulcers, 2 gastric antral vascular ectasia [GAVE]); 15 sub-total gastrectomies (13 adenocarcinomas, 2 GIST); and 7 total gastrectomies (5 adenocarcinomas, 1 GIST, 1 carcinoid). Median follow-up was for 48 months (range, 1-72 months). There was one death, two major and six minor complications. All patients with complications made a satisfactory recovery. CONCLUSIONS Laparoscopic gastrectomy is associated with a low mortality (1.75%) and major morbidity (3.50%). Although technically demanding, especially when a D2 lymphadenectomy is performed, our results have shown that tailored laparoscopic resection based on tumour characteristics with either D1 or D2 lymphadenectomy results in good surgical and oncological outcomes.

Abstract
PURPOSE Laparoscopic appendectomy usually needs 3 ports, 1 for the videoscope and 2 as working channels. The aim of this study was to compare the feasibility and postoperative outcomes of laparoscopic transumbilical single-port appendectomy with conventional three-port appendectomy. METHODS From October 2008 to January 2009, 35 patients underwent single-port appendectomy (SA). Surgical outcomes such as operation time, number of times of parenteral analgesic injected, complication, and hospital stay of 35 patients receiving SA were analyzed and compared with those of 37 patients receiving three-port appendectomy (TA) during the same period. RESULTS Comparing SA with TA, there were no statistically significant differences in operation time (75.9+/-27.4 vs. 66.4+/-21.7 min), times of injected analgesic (0.86+/-1.3 vs. 0.97+/-1.47 times), complication rate (8.6% vs. 2.7%), and hospital stay (3.0+/-1.3 vs. 3.2+/-1.4 d). The most common complication was wound infection (2 cases for SA and 1 for TA). One instance of intra-abdominal fluid accumulation occurred in a patient with perforated appendicitis during SA, and this was managed with image-guided drainage. In contrast to the TA, the abdominal scar in SA was nearly inconspicuous. CONCLUSIONS This study showed SA to be feasible, and it did not show any difference in postoperative outcomes compared with TA. Moreover, SA can produce scarless surgery without the need for specialized instrumentation.

Abstract
OBJECTIVE The aim of this study was to evaluate the safety of this trial with respect to morbidity and mortality. SUMMARY BACKGROUND DATA Laparoscopic-assisted distal gastrectomy (LADG) is rapidly gaining popularity. However, there is limited evidence regarding its oncologic safety. We therefore conducted a phase III multicenter, prospective, randomized study comparing LADG with open gastrectomy (ODG). METHODS Patient eligibility criteria were pathologically-proven adenocarcinoma, 20 to 80 years of age, preoperative stage I, no history of other cancer, chemotherapy, or radiotherapy. The primary end point was to determine whether there is a difference in overall survival between 2 groups. The morbidity and mortality were compared to evaluate the safety of this trial. The time was decided on the hypothesis that the morbidity of this trial was not significantly different from that of previous reports on open gastric cancer surgeries (17%-20%). This study is registered at ClinicalTrials.gov and carries the following ID number: NCT00452751. RESULTS A total of 342 patients were randomized (LADG, 179 patients; ODG, 161 patients) between January 1, 2006 and July 19, 2007. There were no significant differences between the 2 groups in age, gender, and comorbidities. The postoperative complication rates of the LADG and ODG groups were 10.5% (17/179) and 14.7% (24/163), respectively (P = 0.137). Reoperations were required in 3 cases each group. The postoperative mortality was 1.1% (2/179) and 0% (0/163) in the LADG and ODG groups (P = 0.497), respectively. CONCLUSION There was no significance difference in the morbidity and mortality between the 2 groups. Therefore, we conclude that this trial is safe and is thus ongoing.

Abstract
OBJECTIVE To study the data from the Laparoscopic Gastric Surgery Spanish National Register of laparoscopic Gastric Surgery and to analyse the type of surgery, the conversion to laparotomy, postoperative complications and mortality. PATIENTS AND METHOD From March 2005 to July 2008, details of 302 laparoscopic gastric surgical interventions were sent to the Association of Spanish Surgeons web-site. Details of surgical technique, reconversion, clinical and pathological data, morbidity and mortality were collected and analysed. RESULTS A total of 245 patients had gastric adenocarcinoma, 35 of them stromal tumours and 22 other gastric pathologies. In gastric adenocarcinoma patients, resection was performed in 232 cases (95%). The most frequent histology was intestinal, mainly located in the distal third of the stomach, with 34% of the tumours being locally advanced. D2 lymphadenectomy was performed in 117 cases, D1 in 105, and D0 in 6. Reconversion was needed in 21 cases (9%), with technical difficulty being the most frequent cause. Postoperative complications were reported in 72 patients (31%), with anastomotic leak being one of the most significant. Postoperative mortality was 6%, with sepsis due to anastomotic leak and cardiac or respiratory complications the most frequent causes. The mean hospital stay of patients without complications was 9.2 +/- 3 days. CONCLUSIONS Laparoscopic gastrectomy for gastric cancer is a feasible but technically demanding procedure. Potential benefits of minimal invasive surgery can be reduced due to a high rate of postoperative complications.

Abstract
BACKGROUND Fat volume and large abdominal shape are known to disrupt the procedures of lymph node retrieval used in gastric cancer surgery. The present study examined the effect of increasing fat content on surgical outcomes, including estimated blood loss and the number of lymph nodes retrieved during gastrectomy. METHODS Of 154 patients, 50 underwent the conventional open procedure (OPEN) and 104 underwent laparoscopy-assisted distal gastrectomy (LADG). The BMI-related factors of total fat, subcutaneous fat, and visceral fat area, as well as the peritoneum-celiac axis distance were calculated by computed tomography. Regression analysis was used to determine the effects of BMI-related factors that obstruct the surgical procedures on the specific outcomes of estimated blood loss and the number of lymph nodes retrieved. RESULTS In the OPEN, but not in the LADG, increases in all BMI-related factors were related to increases in estimated blood loss. The increases in BMI, subcutaneous fat, and the peritoneum-celiac axis distances were related to decreased numbers of retrieved lymph nodes only in the OPEN. Only the factor of visceral fat at the celiac level was modestly associated with a decreased number of dissected lymph node in both groups. CONCLUSIONS The present study demonstrated that increased fat content and large body shape have little effect on the number of lymph nodes retrieved and blood loss in LADG. However, for patients undergoing conventional open distal gastrectomy, increased fat content and large body shape do impact on the amount of blood lost and the number of lymph nodes retrieved.
