Abstract
PURPOSE We conducted a randomized prospective trial (KLASS-07 trial) to compare laparoscopy-assisted distal gastrectomy (LADG) and totally laparoscopic distal gastrectomy (TLDG) for gastric cancer. In this interim report, we describe short-term results in terms of morbidity and mortality. METHODS AND METHODS The sample size was 442 participants. At the time of the interim analysis, 314 patients were enrolled and randomized. After excluding patients who did not undergo planned surgeries, we performed a modified per-protocol analysis of 151 and 145 patients in the LADG and TLDG groups, respectively. RESULTS The baseline characteristics, including comorbidity status, did not differ between the LADG and TLDG groups. Blood loss was somewhat higher in the LADG group, but statistical significance was not attained (76.76±72.63 vs. 62.91±65.68 mL; P=0.087). Neither the required transfusion level nor the operation or reconstruction time differed between the 2 groups. The mini-laparotomy incision in the LADG group was significantly longer than the extended umbilical incision required for specimen removal in the TLDG group (4.79±0.82 vs. 3.89±0.83 cm; P<0.001). There were no between-group differences in the time to solid food intake, hospital stay, pain score, or complications within 30 days postoperatively. No mortality was observed in either group. CONCLUSIONS Short-term morbidity and mortality rates did not differ between the LADG and TLDG groups. The KLASS-07 trial is currently underway. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT03393182.

Application of Overlap Gastroduodenostomy in Billroth I Anastomosis after Totally Laparoscopic Distal Gastrectomy for Gastric Cancer. Can J Gastroenterol Hepatol 2022; 2022:9094934. [PMID: 35991365 PMCID: PMC9391180 DOI: 10.1155/2022/9094934] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/11/2022] [Revised: 07/01/2022] [Accepted: 07/16/2022] [Indexed: 11/29/2022] Open
Abstract
Delta-shaped gastroduodenostomy (DSGD) and overlap gastroduodenostomy (OGD) are the two most widely used intracorporeal Billroth I anastomosis methods after distal gastrectomy. In this study, we compared the short-term outcomes of DSGD and OGD in total laparoscopic distal gastrectomy (TLDG). In a retrospective cohort study, we examined 92 gastric cancer patients who underwent TLDG performed by the same surgeon between January 2014 and June 2018. All patients underwent Billroth I reconstruction (OGD, n = 45; DSGD, n = 47) and D2 lymph node dissection. We retrospectively reviewed the surgical outcomes, clinical pathological results, and endoscopy results. Laparoscopic surgery was successfully performed in both groups without conversion to open surgery. The demographic and clinical characteristics were similar between the two groups (P > 0.05). There were no significant differences between the two groups in operation time (158.9 ± 13.6 min vs. 158.8 ± 14.8 min, P=0.955), anastomotic time (19.4 ± 3.0 min vs. 18.8 ± 2.9 min, P=0.354), intraoperative blood loss (88.9 ± 25.4 mL vs. 83.7 ± 24.3 mL, P=0.321), number of lymph node dissections (31.0 ± 7.1 vs. 29.2 ± 7.5, P=0.229), length of hospital stay (8.8 ± 2.7 days vs. 9.1 ± 3.0 days, P=0.636), fluid intake time (3.1 ± 0.7 days vs. 3.2 ± 0.7 days, P=0.914), and morbidity of postoperative complications (6.7% [3/45] vs. 10.6% [5/47], P=0.499). Endoscopy performed 6 months postoperatively showed that the residual food (P=0.033), gastritis (P=0.029), and bile (P=0.022) classification score significantly decreased in the OGD group, and there were no significant differences 12 months postoperatively. OGD is a safe and effective reconstruction technique with comparable postoperative surgical outcomes and endoscopy results when compared with those of DSGD.

Abstract
Objective A multicenter retrospective cohort study was performed to compare the outcomes of laparoscopic gastrectomy (LG) versus open gastrectomy (OG) for scirrhous gastric cancer (GC) as a unique subtype also known as type 4 gastric cancer or linitis plastica. Background Although data on the efficacy and safety of LG as an alternative to OG are emerging, the applicability of LG to scirrhous GC remains unclear. Methods Patients with clinical type 4 GC undergoing gastrectomy at 13 hospitals from 2005 to 2015 were retrospectively reviewed. As the primary endpoint, we compared overall survival (OS) between the LG and OG groups. To adjust for confounding factors, we used multivariate Cox regression analysis for the main analyses and propensity-score matching for sensitivity analysis. Short-term outcomes and recurrence-free survival were also compared. Results A total of 288 patients (LG, 62; OG, 226) were included in the main analysis. Postoperative complications occurred in 25.8% and 30.1%, respectively (P = 0.44). No significant difference in recurrence-free survival was observed (P = 0.72). The 5-year OS rates were 32.4% and 31.6% in the LG and OG groups, respectively (P = 0.60). The hazard ratio (LG/OG) for OS was 0.98 (95% confidence interval [CI], 0.65-1.43) in the multivariate regression analysis. In the sensitivity analyses after propensity-score matching, the hazard ratio for OS was 0.92 (95% CI, 0.58-1.45). Conclusions Considering the hazard ratios and 95% CIs for OS, LG for scirrhous GC was not associated with worse survival than that for OG.

[PMID: 32026335 DOI: 10.1007/s11605-020-04516-7] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/09/2019] [Accepted: 01/03/2020] [Indexed: 01/31/2023]
Abstract
BACKGROUND We invented a simple and secure method of intracorporeal gastroduodenostomy, the delta-shaped anastomosis (DA), using endoscopic linear stapler only and standardized the DA procedure by resecting two-thirds of the stomach based on the anatomical landmarks. This study aimed to evaluate the feasibility of the standardized DA as the standard reconstruction procedure after a laparoscopic distal gastrectomy assessing functional outcomes including postoperative complications, body weight loss, nutritional status, and endoscopic findings. METHODS The medical records of 349 patients with gastric cancer who underwent laparoscopic distal gastrectomy from April 2011 to December 2017 at our hospital were retrospectively reviewed. Functional outcomes were assessed according to nutritional status and endoscopic findings. RESULTS The operation time was shorter and complication rate was lower in the standardized DA than those in Billroth-II (BII) and Roux-en-Y (RY). The body weight loss in DA was 10% 1 year postoperatively and remained stable during the follow-up period, which showed no significant difference. The endoscopic findings showed the ratio of residual food in DA was lower than that in RY (DA:RY = 13.3%:13.6% and 8.4%:33.3% at 1 and 3 years postoperatively, respectively). Severe gastritis was extremely rare in DA (6.7% at 1 year and 15.6% at 3 years postoperatively). Bile reflux was more often found in DA than RY (DA:RY = 19.9%:4.8% and 26.6%:0% at 1 and 3 years postoperatively, respectively). Reflux esophagitis was found 10% of DA only. CONCLUSIONS Functional outcomes of the standardized DA were satisfactory and feasible. Our intracorporeal Billroth-I reconstruction, by resecting two-thirds of the stomach, can be one of the standard reconstruction methods after a laparoscopic distal gastrectomy.

Preventive procedure for stenosis after esophagojejunostomy using a circular stapler and transorally inserted anvil (OrVil™) following laparoscopic proximal gastrectomy and total gastrectomy involving reduction of anastomotic tension. BMC Surg 2021; 21:47.

Abstract
Background Recently, due to increasing reports of stenosis after esophagojejunostomy created using circular staplers and a transorally inserted anvil (OrVil™) following laparoscopic proximal gastrectomy (LPG) and total gastrectomy (LTG), linear staplers are being used instead. We investigated our preventive procedure for esophagojejunostomy stenosis following use of circular staplers. Methods Since the anastomotic stenosis is considered to be mainly caused by tension in the esophageal and jejunal stumps at the anastomotic site, we have been performing procedures to relieve this tension, by cutting off the rubber band and pushing the shaft of the circular stapler toward the esophageal side, since July 2015. We retrospectively compared the incidence of anastomotic stenosis in cases of LPG and LTG performed before July 2015 (early phase, 30 cases) versus those performed after this period (later phase, 22 cases). Results Comparison of the incidence of anastomotic stenosis according to the type of surgery, LPG or LTG, and between the two time periods versus all cases, indicated a significantly lower incidence in the later phase than in the early phase (4.5 vs. 26.7%, p < 0.05), especially for LPG (0 vs. 38.5%, p < 0.05). Conclusions It is possible to use a circular stapler during laparoscopic esophagojejunostomy, as with open surgery, if steps to reduce tension on the anastomotic site are undertaken. These procedures will contribute to the spread of safe and simple laparoscopic anastomotic techniques.

Abstract
Background
The use of totally laparoscopic surgery with Billroth-I reconstruction (delta-shaped anastomosis) has rapidly become widespread in recent years. However, we experienced delayed gastric emptying (DGE) in the early period after introduction of this technique. To the best of our knowledge, there are no reports that mention the incision line when discussion prevention of DGE in distal gastrectomy. In the present study, we standardized the surgical techniques, including the gastric incision line, and compared the short-term results before and after standardization.
Methods
A total of 86 patients were enrolled in this study. Twenty-eight procedures were performed in the early period, 58 procedures were performed in the late period, and the 2 groups were compared retrospectively.
Results
The operation time decreased significantly after standardization from 288 to 224 minutes (P < 0.001). The median value of perioperative bleeding volume decreased from 22.5 to 12.5 mL (P = 0.060). There were no postoperative complications related to the site of anastomosis in either group. Five cases of DGE (17.8%) were noted in the early period, but only 2 cases (3.4%) were noted in the late period (P = 0.022).
Conclusions
Standardization of the incision line after laparoscopic gastrectomy resulted in a decrease in the incidence of DGE.

Abstract
PURPOSE We evaluate surgical outcomes of intracorporeal esophagojejunostomy in laparoscopic total gastrectomy using 2 linear stapler methods. MATERIALS AND METHODS The functional end-to-end anastomosis (FEEA) method was chosen as a first choice. The overlap method was chosen in cases with esophageal invasion. We retrospectively analyzed the early and late surgical outcomes of consecutive 168 laparoscopic total gastrectomy cases from April 2011 to December 2016. RESULTS AND CONCLUSIONS The FEEA method was selected in 120 cases, and the overlap method was selected in 48 cases. The mean time of esophagojejunostomy for the FEEA and overlap method was 13.2 and 36.5 minutes, respectively. Two cases with FEEA method and 3 cases with overlap method experienced complications due to esophagojejunostomy leakage. These cases were treated without performing a reoperation. One case with FEEA method was complicated due to esophagojejunostomy stenosis. This case was endoscopically treated. Our procedures are safe and feasible.

Stapling an extracorporeal Billroth-I anastomosis by the complete double stapling technique after laparoscopy-assisted distal gastrectomy. Asian J Endosc Surg 2017; 10:137-142. [PMID: 28127939 DOI: 10.1111/ases.12357] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2016] [Revised: 10/31/2016] [Accepted: 12/18/2016] [Indexed: 12/23/2022]
Abstract
INTRODUCTION Laparoscopy-assisted distal gastrectomy is one of the major treatments for early stage gastric cancer, particularly in the East Asia. In this method, extracorporeal anastomosis is performed via a small laparotomy wound, but excessive tissue traction may be encountered during the anastomotic procedure. Therefore, we developed an original procedure for extracorporeal Billroth-I reconstruction: end-to-end stapling gastroduodenostomy with complete double stapling technique. This procedure aims to reduce the problems related to maneuvers through a small laparotomy. METHODS An end-to-end anastomosis is constructed on the transection line using a circular stapler inserted from the distal end of the greater curvature of the remnant stomach. Short-term outcomes were reviewed in 218 consecutive patients who underwent complete double stapling technique reconstruction after laparoscopy-assisted distal gastrectomy between 2002 and 2012. Findings from GI endoscopy were reviewed in 110 patients. RESULTS The mean operative time was 216 min, and mean blood loss was 163 mL. There was no conversion to the open surgery and no operative death. Eight patients (3.6%) had anastomosis-related postoperative complications. In follow-up endoscopic examinations 1 year after surgery, grade 3 or higher residual food was seen in 17.2% of patients. Gastritis extending to the entire remnant stomach was observed in 8.2% of patients, and grade 3 gastritis was seen in 2.7%. Los Angeles classification grade A or higher reflux esophagitis was found in 10.9%. CONCLUSIONS Billroth-I reconstruction by the complete double stapling technique is a safe and feasible procedure. This method provides satisfactory short-term outcomes, including the incidence of reflex remnant gastritis and esophagitis.

Abstract
BACKGROUND To evaluate feasibility and benefits of intracorporeal anastomosis, we compared short-term surgical outcomes between laparoscopy-assisted distal gastrectomy (LADG) and totally laparoscopic distal gastrectomy (TLDG) with Billroth-II (B-II) anastomosis for gastric cancer. METHODS Sixty patients underwent attempted B-II TLDG from 2011 through 2013. Patients who underwent B-II LADG prior to 2011 were matched to TLDG cases for demographics, comorbidities, tumor characteristics, and TNM stage. Perioperative and short-term surgical outcomes were compared between the two groups. RESULTS Clinicopathological characteristics of both groups were comparable. The B-II TLDG group had a shorter hospital stay (9.4 vs. 12.0 days, P = 0.038) and average incision size was smaller (3.5 vs. 5.4 cm, P = 0.030) than in the B-II LADG group. Anastomotic leakage was not recorded in either group, and there were no differences in the rates of perioperative complications and in inflammatory parameters between the two groups. CONCLUSIONS This study suggests that B-II TLDG is feasible, compared to B-II LADG, and that it has several advantages over LADG, including a smaller incision, a shorter hospital stay, and more convenience during surgery. However, prospective randomized controlled studies are still needed to confirm that B-II TLDG can be used as a standard procedure for LDG.

Abstract
Minimally invasive surgery (MIS) for upper gastrointestinal (GI) cancer, characterized by minimal access, has been increasingly performed worldwide. It not only results in better cosmetic outcomes, but also reduces intraoperative blood loss and postoperative pain, leading to faster recovery; however, endoscopically enhanced anatomy and improved hemostasis via positive intracorporeal pressure generated by CO2 insufflation have not contributed to reduction in early postoperative complications or improvement in long-term outcomes. Since 1995, we have been actively using MIS for operable patients with resectable upper GI cancer and have developed stable and robust methodology in conducting totally laparoscopic gastrectomy for advanced gastric cancer and prone thoracoscopic esophagectomy for esophageal cancer using novel technology including da Vinci Surgical System (DVSS). We have recently demonstrated that use of DVSS might reduce postoperative local complications including pancreatic fistula after gastrectomy and recurrent laryngeal nerve palsy after esophagectomy. In this article, we present the current status and future perspectives on MIS for gastric and esophageal cancer based on our experience and a review of the literature.

Totally laparoscopic gastrectomy using intracorporeally stapler or hand-sewn anastomosis for gastric cancer: a single-center experience of 478 consecutive cases and outcomes. World J Surg Oncol 2016; 14:115. [PMID: 27094509 PMCID: PMC4837503 DOI: 10.1186/s12957-016-0868-7] [Citation(s) in RCA: 21] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2015] [Accepted: 04/12/2016] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND Totally laparoscopic gastrectomy (TLG) using intracorporeal anastomosis has gradually become mature thanks to the advancements of laparoscopic surgical instruments and the accumulation of operative experience. The goal of this study is to review our institution's experience with TLG for the treatment of gastric cancer. METHODS A retrospective study was conducted to examine the short-term outcomes of TLG using intracorporeally stapler or hand-sewn anastomosis performed at Sir Run Run Shaw Hospital between March 2007 and June 2015. The details of intracorporeal anastomosis were described, and the clinicopathological data, surgical outcomes, and postoperative complications were evaluated. RESULTS Four hundred seventy-eight patients were included in the study. Generally speaking, the patients could be divided into stapler or hand-sewn groups according to whether intracorporeal anastomosis was performed by only hand-sewn technique (n = 97) or only stapling devices (n = 381). For overall patients, the mean operation time and anastomotic time were 225.7 and 30.0 min, respectively. Postoperative complications were observed in 65 patients. All of the patients recovered well without perioperative death by conservative or surgical management. CONCLUSIONS TLG using intracorporeally stapler or hand-sewn anastomosis is a reasonable option for the treatment of gastric cancer, with early data showing acceptable perioperative outcomes.

Abstract
BACKGROUND Although delta-shaped gastroduodenostomy (DSGD) is used increasingly as an intracorporeal Billroth I anastomosis after distal gastrectomy, worries about anatomical distortion always exist in twisting stomach and making an oblique incision on duodenum. We developed a new method of intracorporeal gastroduodenostomy, the linear-shaped gastroduodenostomy (LSGD), in which anastomosis is done using endoscopic linear staplers only without any complicated rotation. In this report, we introduced LSGD and compared its short-term and long-term outcomes with DSGD. METHODS We analyzed 261 consecutive gastric cancer patients who underwent the intracorporeal gastroduodenostomy between January 2009 and May 2014 (LSGD: 190, DSGD: 71), retrospectively. All of them underwent a laparoscopic or robotic distal gastrectomy with regional lymph node dissection. Early surgical outcomes such as operation time, postoperative complications, days until soft diet began, length of hospital stay, and endoscopic findings in postoperative 6 and 12 months were evaluated. RESULTS Although the proportion of robotic approach and D2 lymphadenectomy were significantly higher in LSGD group, the rates for overall complications (13.2 % [LSGD] vs. 9.9 % [DSGD], p = 0.470) and major complications (5.8 vs. 5.6 %, p = 1.0) were similar between two groups. There were no differences in anastomotic bleeding (1.1 vs. 1.4 %, p = 1.0), stenosis (3.2 vs. 2.8 %, p = 1.0), and leakage (0.5 vs. 0.0 %, p = 1.0). Endoscopy performed 6 months postoperatively showed that residual food (p = 0.022), gastritis (p = 0.018), and bile reflux (42.0 vs. 63.2 %, p = 0.003) were significantly decreased in LSGD and there were no significant differences in postoperative 12 months. CONCLUSION LSGD is an innovative reconstruction technique with comparable short-term outcomes to DSGD. In addition, reduced residual food, gastritis, and bile reflux were seen in LSGD.

Abstract
Laparoscopic gastrectomy has been widely accepted as a standard alternative for the treatment of early-stage gastric adenocarcinoma because of its favorable short-term outcomes. Although controversies exist, such as establishing clear indications, proper preoperative staging, and oncologic safety, experienced surgeons and institutions have applied this approach, along with various types of function-preserving surgery, for the treatment of advanced gastric cancer. With technical advancement and the advent of state-of-the-art instruments, indications for laparoscopic gastrectomy are expected to expand as far as locally advanced gastric cancer. Laparoscopic gastrectomy appears to be promising; however, scientific evidence necessary to generalize this approach to a standard treatment for all relevant patients and care providers remains to be gathered. Several multicenter, prospective randomized trials in high-incidence countries are ongoing, and results from these trials will highlight the short- and long-term outcomes of the approach. In this review, we describe up-to-date findings and critical issues regarding laparoscopic gastrectomy for gastric cancer.

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.

Delta-shaped anastomosis, a good substitute for conventional Billroth I technique with comparable long-term functional outcome in totally laparoscopic distal gastrectomy. Surg Endosc 2014; 29:2545-52.

Abstract
BACKGROUND Delta-shaped anastomosis (DA) is a new Billroth I reconstruction technique using only a laparoscopic linear stapler under a totally laparoscopic approach. The present study compared the outcomes of DA with those of laparoscopic conventional Billroth I anastomosis (cBIA). METHODS A total of 138 and 100 patients with gastric cancer who underwent laparoscopic distal gastrectomy with DA and cBIA, respectively, were selected. Clinicopathological data and short- and long-term outcomes were compared between the two groups. RESULTS The mean operating time in the DA group was similar to that in the cBIA group. Short-term outcomes, such as bowel function recovery, morbidity, and mortality, did not differ between the DA and cBIA groups. There were no significant differences in the 5-year disease-free and overall survival rates between the two groups. All nutritional indices (body weight change, albumin level, transferrin level, and total lymphocyte count) were similar between the two groups with the exception of a few points in the early follow-up period. Endoscopic evaluation using the Residual food, Gastritis, Bile reflux classification revealed relatively better gastritis findings in the DA group despite worse bile reflux for 5 postoperative years. The food amount was significantly larger in the DA group for 2 postoperative years. CONCLUSIONS The outcomes of DA were comparable to those of cBIA. DA is a recommendable reconstruction method, especially in totally laparoscopic distal gastrectomy.

Totally laparoscopic total gastrectomy for gastric cancer: literature review and comparison of the procedure of esophagojejunostomy. Asian J Surg 2014; 38:102-12.

Abstract
There has been a recent increase in the use of totally laparoscopic total gastrectomy (TLTG) for gastric cancer. However, there is no scientific evidence to determine which esophagojejunostomy (EJS) technique is the best. In addition, both short- and long-term oncological results of TLTG are inconsistent. We reviewed 25 articles about TLTG for gastric cancer in which at least 10 cases were included. We analyzed the short-term results, relationships between EJS techniques and complications, long-term oncological results, and comparative study results of TLTG. TLTG was performed in a total of 1170 patients. The mortality rate was 0.7%, and the short-term results were satisfactory. Regarding EJS techniques and complications, circular staplers (CSs) methods were significantly associated with leakage (4.7% vs. 1.1%, p < 0.001) and stenosis (8.3% vs. 1.8%, p < 0.001) of the EJS as compared with the linear stapler method. The long-term oncological prognosis was acceptable in patients with early gastric cancers and without metastases to lymph nodes. Although TLTG tended to increase surgical time compared with open total gastrectomy and laparoscopy-assisted total gastrectomy, it reduced intraoperative blood loss and was expected to shorten postoperative hospital stay. TLTG is found to be safer and more feasible than open total gastrectomy and laparoscopy-assisted total gastrectomy. At present, there is no evidence to encourage performing TLTG for patients with advanced gastric cancer from the viewpoint of long-term oncological prognosis. Although the current major EJS techniques are CS and linear stapler methods, in this review, CS methods are significantly associated with leakage and stenosis of the EJS.

Abstract
BACKGROUND Intracorporeal Billroth I (ICBI) (delta-shaped) anastomosis is being increasingly used for laparoscopic distal gastrectomy. However, few studies have focused on the safety and feasibility of adopting this new technique. The present study aimed to review the surgical outcomes after the initial experience of performing ICBI anastomosis and to evaluate whether this technique can be safely adopted without increasing operative risk during the early learning process. METHODS Forty-two consecutive patients who underwent ICBI anastomosis with laparoscopic distal gastrectomy by a single surgeon were enrolled, and their operative outcomes and hospital course were compared with those of 179 patients who underwent conventional extracorporeal Billroth I (ECBI) anastomosis by the same operator. The learning curve was assessed by evaluating the moving average of anastomosis time. RESULTS The operating time in the ICBI group was significantly longer than that in the ECBI group (142 vs. 116 min, p < 0.001). However, there were no significant differences in the postoperative hospital course such as gas passage, diet initiation, postoperative fever, and hospital stay between the two groups. Postoperative morbidity did not significantly differ between the ICBI and ECBI groups (7.1 vs. 12.3 %, p = 0.428). No anastomosis-related complications occurred in the ICBI group. The mean anastomosis time for ICBI anastomosis was 24 ± 5 min, and the anastomosis average time curve showed that it reached a plateau approximately after the 14th case. CONCLUSIONS ICBI anastomosis has a steep learning curve without increasing operative risk in the early learning process, when performed by experienced laparoscopic surgeons. The technical feasibility and clinical advantages of intracorporeal anastomosis need to be proven in future clinical trials.

Abstract
BACKGROUND We introduced a new, safe and simple intracorporeal Billroth II (B-II) gastrojejunostomy technique using laparoscopic linear staplers with totally laparoscopic distal gastrectomy (TLDG) for gastric cancer. We further compared the short-term operative outcomes between intracorporeal B-II gastrojejunostomy with TLDG and extracorporeal B-II gastrojejunostomy with laparoscopy-assisted distal gastrectomy (LADG). METHODS From January 01, 2012 to January 31, 2013, a total of 36 patients with gastric cancer underwent TLDG and LADG. Overall, 11 patients underwent intracorporeal B-II gastrojejunostomy with TLDG, and 25 patients underwent a mini-laparotomy incision for extracorporeal B-II anastomosis with LADG. Perioperative parameters, including patient and tumor characteristics, short-term postoperative outcomes, and anastomosis-related complications, were analyzed to compare the two operations. RESULTS The time to first flatus, the time on a liquid diet, and the mean postoperative length of hospital stay were significantly different between the groups (P < 0.05). In the TLDG group, the postoperative time to first flatus and the mean postoperative length of hospital stay were significantly shorter than in the LADG group (2.6 ± 0.20 vs. 3.8 ± 0.1 days; 10 ± 1.84 vs. 12.7 ± 3.35 days). However, the operation-related costs were significantly greater for totally laparoscopic distal gastrectomy (P < 0.001). The mean number of staples used in TLDG was six compared with four in LADG. CONCLUSION Our new intracorporeal B-II anastomosis method using laparoscopic linear staplers with TLDG was safe, feasible, and minimally invasive compared with extracorporeal B-II gastrojejunostomy with LADG. At the same time, one of its characteristics of our technique is to avoid stricturing of the efferent loop or afferent loop of the jejunum when the entry hole is closed with a stapler.

Impact of NPM, TFF3 and TACC1 on the prognosis of patients with primary gastric cancer. PLoS One 2013; 8:e82136.

Abstract
Background NPM, TFF3 and TACC1 are molecular markers that play important roles in cell differentiation. Herein, we investigated their prognostic impact in patients with primary gastric cancer (GC) and determined whether they could be used as markers of more aggressive gastric carcinomas by detecting the extent of expression in human gastric carcinoma samples. Methodology/Principal Findings Tumor tissue specimens from 142 GC patients were retrospectively retrieved and immunohistochemically evaluated. Correlations between NPM, TFF3 and TACC1 over-expression and clincopathologic parameters, and their prognostic values were investigated with χ2, Kaplan-Meier method, and Cox uni- and multivariate survival models. NPM, TFF3 and TACC1 expression was significantly higher in GC patients with poorly differentiated histologic type than that in patients with well differentiated histologic type. NPM expression was significantly higher in patients with hepatic metastasis or recurrence than that in patients without metastasis. TFF3 expression was significantly higher in patients with positive lymph node metastasis than that in patients with negative lymph node metastasis. Age, lymph node metastasis, and TFF3 and TACC1 over-expression were significantly correlated with low survival (P<0.05, P<0.05, P = 0.005 and P = 0.009, respectively). Multivariate analysis showed that lymph node metastasis and TFF3 and TACC1 over-expression were independent prognostic factors. Conclusions TFF3 and TACC1 over-expression in epithelial cells of surgically resected GC tissues was an independent predictor of short survival in GC patients. The prognosis was poorer in patients with positive expression of both TFF3 and TACC1 than that in patients with positive expression of TFF3 or TACC1 alone, or with negative expression of TFF3 and TACC1.

Abstract
Purpose The aims are to: (i) display the multidimensional learning curve of totally laparoscopic distal gastrectomy, and (ii) verify the feasibility of totally laparoscopic distal gastrectomy after learning curve completion by comparing it with laparoscopy-assisted distal gastrectomy. Materials and Methods From January 2005 to June 2012, 247 patients who underwent laparoscopy-assisted distal gastrectomy (n=136) and totally laparoscopic distal gastrectomy (n=111) for early gastric cancer were enrolled. Their clinicopathological characteristics and early surgical outcomes were analyzed. Analysis of the totally laparoscopic distal gastrectomy learning curve was conducted using the moving average method and the cumulative sum method on 180 patients who underwent totally laparoscopic distal gastrectomy. Results Our study indicated that experience with 40 and 20 totally laparoscopic distal gastrectomy cases, is required in order to achieve optimum proficiency by two surgeons. There were no remarkable differences in the clinicopathological characteristics between laparoscopy-assisted distal gastrectomy and totally laparoscopic distal gastrectomy groups. The two groups were comparable in terms of open conversion, combined resection, morbidities, reoperation rate, hospital stay and time to first flatus (P>0.05). However, totally laparoscopic distal gastrectomy had a significantly shorter mean operation time than laparoscopy-assisted distal gastrectomy (P<0.01). We also found that intra-abdominal abscess and overall complication rates were significantly higher before the learning curve than after the learning curve (P<0.05). Conclusions Experience with 20~40 cases of totally laparoscopic distal gastrectomy is required to complete the learning curve. The use of totally laparoscopic distal gastrectomy after learning curve completion is a feasible and timesaving method compared to laparoscopy-assisted distal gastrectomy.

Abstract
Laparoscopic gastrectomy has been widely accepted especially in patients with early-stage gastric cancer. However, the safety and oncologic validity of laparoscopic gastrectomy for advanced gastric cancer are still being debated. Since the late 90s', we have been engaged in developing a stable and robust methodology of laparoscopic radical gastrectomy for advanced gastric cancer, and have established laparoscopic distinctive technique for suprapancreatic lymph node dissection, namely the outermost layer-oriented medial approach. In this article, We present the development history of this method, and current status and future perspectives of laparoscopic gastrectomy for advanced gastric cancer based on our experience and a review of the literature.
