Abstract
Background Compared to distal gastrectomy (DG), pylorus-preserving gastrectomy (PPG), a peristaltic function-preserving surgery for early gastric cancer (EGC), is advantageous as it leads to a more improved nutritional status and quality of life (QOL) of patients. In recent years, total laparoscopic PPG (TLPPG), an anastomosis which is performed intracorporeally, has increasingly replaced laparoscopic-assisted PPG (LAPPG) due to its minimal invasiveness. Aim To evaluate the safety and feasibility of TLPPG in terms of perioperative efficacy. Patients Three patients underwent TLPPG in the Affiliated Hospital of Changzhi Medical College from September 2021 to March 2022. Methods Surgical safety analysis: Our three cases (TLPPG group) were compared to data from the CLASS-02 study, which collected data from multiple centers across China for the laparoscopic total gastrectomy (LTG group). The CLASS-02 study provides data from the most invasive type of gastric surgery, providing solid comparative data to our own.Postoperative short-term efficacy analysis: Patient questionnaire responses provided data on postoperative nutritional and QOL status. Results from our three cases were compared to the Japanese multicenter data PGSAS-37 (PGSAS group). Results There were no complications or deaths occurred during or after operation in our cases. Compared to the PGSAS group, our cases scored lower for abdominal pain, dyspepsia, and weight loss. Conclusion Although more case information is needed, our findings demonstrate that TLPPG may be a possible and effective treatment for EGC in China, similar to that in Japan.

Intracorporeal hand-sewn anastomosis following pylorus-preserving gastrectomy: surgical technique and short-term surgical outcome. Langenbecks Arch Surg 2022; 407:1711-1720. [PMID: 35670857 DOI: 10.1007/s00423-022-02575-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2021] [Accepted: 05/29/2022] [Indexed: 10/18/2022]
Abstract
BACKGROUND Although several procedures for mechanical anastomosis have recently been reported, intracorporeal manually hand-sewn anastomosis for totally laparoscopic pylorus-preserving gastrectomy (TLPPG) is considered technically difficult. Here, we report a new technique for laparoscopic reconstruction using hand-sewn sutures. METHODS Together with a proper lymphadenectomy, the stomach was detached and resected using separate two-layer incisions, similar to the original laparotomy method. An approximately 5-cm antral cuff was left in place. The essential concept of this new method was to align the anastomotic site by rotating each clamped gastric stump. This allowed us to perform a secure, hand-sewn, two-layer anastomosis successfully. The short-term surgical outcome after TLPPG was retrospectively compared with that for patients who underwent a conventional laparoscopy-assisted procedure (LAPPG). RESULTS Of the 20 consecutive patients who underwent pylorus-preserving gastrectomy in our department between 2014 and 2021, the first 8 patients and the subsequent 12 patients underwent LAPPG and TLPPG, respectively. The operation time was significantly longer in the TLPPG group (median, 302 vs. 269 min). The morbidity was comparable (8.3% in TLPPG vs. 12.5% in LAPPG). Postoperative delayed gastric emptying was only observed in one patient in the LAPPG group. TLPPG reduced the cost of the operation by reducing the number of linear stapler cartridges required. CONCLUSION A purely hand-sewn gastrogastrostomy is safe, feasible, and cost-effective, and it omits the need for a mini-laparotomy in the upper abdomen.

Abstract
Background Perioperative blood transfusion reserves are limited, and the outcome of blood transfusion remains unclear. Therefore, it is important to prepare plans for perioperative blood transfusions. This study aimed to establish a risk assessment model to guide clinical patient management. Methods This retrospective comparative study involving 513 patients who had total gastrectomy (TG) between January 2018 and January 2021 was conducted using propensity score matching (PSM). The influencing factors were explored by logistic regression, correlation analysis, and machine learning; then, a nomogram was established. Results After assessment of the importance of factors through machine learning, blood loss, preoperative controlling nutritional status (CONUT), hemoglobin (Hb), and the triglyceride–glucose (TyG) index were considered as the modified transfusion-related factors. The modified model was not considered to be different from the original model in terms of performance, but is simpler. A nomogram was created, with a C-index of 0.834, and the decision curve analysis (DCA) demonstrated good clinical benefit. Conclusions A nomogram was established and modified with machine learning, which suggests the importance of the patient’s integral condition. This emphasizes that caution should be exercised regarding transfusions, and, if necessary, preoperative nutritional interventions or delayed surgery should be implemented for safety.

Short-term Outcomes of Pylorus-Preserving Gastrectomy for Early Gastric Cancer: Comparison Between Extracorporeal and Intracorporeal Gastrogastrostomy. J Gastric Cancer 2022; 22:135-144. [PMID: 35534450 PMCID: PMC9091456 DOI: 10.5230/jgc.2022.22.e16] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/19/2021] [Revised: 04/07/2022] [Accepted: 04/07/2022] [Indexed: 12/02/2022] Open
Abstract
Purpose This study aimed to compare the surgical and oncological outcomes between totally laparoscopic pylorus-preserving gastrectomy (TLPPG) with intracorporeal anastomosis and laparoscopy-assisted pylorus-preserving gastrectomy (LAPPG) with extracorporeal anastomosis. Materials and Methods A retrospective analysis was performed in 258 patients with cT1N0 gastric cancer who underwent laparoscopic pylorus-preserving gastrectomy using two different anastomosis methods: TLPPG with intracorporeal anastomosis (n=88) and LAPPG with extracorporeal anastomosis (n=170). The following variables were compared between the two groups to assess the postoperative surgical and oncological outcomes: proximal and distal margins, number of resected lymph nodes (LNs) in total and in LN station 6, operation time, postoperative hospital stay, and postoperative morbidity including delayed gastric emptying (DGE). Results The average length of the proximal margin was similar between the TLPPG and LAPPG groups (2.35 vs. 2.73 cm, P=0.070). Although the distal margin was significantly shorter in the TLPPG group than in the LAPPG group (3.15 vs. 4.08 cm, P=0.001), no proximal or distal resection margin-positive cases were reported in either group. The average number of resected LN was similar in both groups (36.0 vs. 33.98, P=0.229; LN station 6, 5.72 vs. 5.33, P=0.399). The operation time was shorter in the TLPPG group than in the LAPPG (200.17 vs. 220.80 minutes, P=0.001). No significant differences were observed between the two groups in terms of postoperative hospital stay (9.38 vs. 10.10 days, P=0.426) and surgical complication rate (19.3% vs. 22.9%), including DGE (8.0% vs. 11.8%, P=0.343). Conclusions The oncological safety and postoperative complications of TLPPG with intracorporeal anastomosis are similar to those of LAPPG with extracorporeal anastomosis.

Abstract
BACKGROUND The number of overweight gastric cancer patients who are undergoing laparoscopic gastrectomy (LG) has increased in Japan. However, the relationship between obesity and surgical outcomes of LG remains unclear. Therefore, this study aimed to evaluate the effect of visceral fat area (VFA) on surgical outcomes of LG for gastric cancer compared to the body mass index (BMI). METHODS This study was a retrospective, cohort study that included 587 patients who underwent LG in our institution between January 2015 and December 2019. The patients were divided into two groups according to VFA (< 100 cm2 and ≥ 100 cm2) and BMI (< 25 kg/m2 and ≥ 25 kg/m2) values, respectively. Surgical outcomes and postoperative complications were compared between the low and high groups for each VFA and BMI value. Propensity score matching was used to minimize potential selection bias. RESULTS After propensity score matching, 144 pairs of patients in the VFA group and 82 pairs of patients in the BMI group were extracted. Operative time (p = 0.003), intraoperative blood loss (p = 0.0006), and CRP levels on postoperative day 1 (p = 0.002) and on postoperative day 3 (p = 0.004) were significantly higher in the high-VFA group than in the low-VFA group. However, these surgical outcomes were not significantly different between the high-BMI and low-BMI groups. There was no strong correlation between VFA and BMI (R2 = 0.64). There were no significant differences in postoperative complications between the high and low groups for both VFA and BMI values. On multivariate analysis, high VFA was an independent predictor of operative time, but it was not significantly associated with the incidence of postoperative complications. CONCLUSION VFA is a better indicator of longer operative time than BMI. However, increased VFA did not affect postoperative complications.

Abstract
IMPORTANCE Segmental gastrectomy, a type of function-preserving surgery, is not broadly studied but can improve postoperative function and quality of life among patients with gastric cancer (GC). OBJECTIVE To establish an indication for middle segmental gastrectomy (MSG) as a treatment for middle-body (MB) and high-body (HB) GC. DESIGN, SETTING, AND PARTICIPANTS This cohort study analyzed patients with GC undergoing surgery between January 2000 and December 2015 in the National Cancer Center, Goyang, Korea, a high-volume cancer center with a structured database and accurate long-term follow-up. Inclusion criteria were age 18 to 85 year, histologically proven adenocarcinoma located in the HB or MB, cT1 to cT3 category cancers, curative resection with negative margins performed, and follow-up for at least 3 years. Exclusion criteria were Borrmann type 4 GC, T4 category cancer, neoadjuvant chemotherapy, and a history of other cancers. Data analysis was performed from December 2018 to May 2020. EXPOSURES Total or subtotal gastrectomy and LN dissection. MAIN OUTCOME AND MEASURES The primary outcome was the rate of metastasis at LN stations 2, 4sa, 5, 6, and 11d, which cannot be dissected during MSG. RESULTS Among 9952 patients who underwent surgery for GC, 8219 underwent either laparoscopic or open total or subtotal gastrectomy. Seven hundred seventy-three patients (mean [SD] age, 56.21 [12.16] years; 464 men [60.0%]) had GC in the MB or HB of the stomach. Among the 701 patients included in the final analysis after exclusion of the cN2/N3 carcinomas, the mean (SD) age was 56.35 (12.24) years, and 418 (59.6%) were men. The incidence of LN metastasis was 0% at station 5 for cT1-3N0/1M0 cancers, station 4sa for cT1-2N0/1M0 cancers, station 2 for cT1N0/1M0 cancers, station 6 for cT1N1M0 cancers, station 11d for cT1N1M0-cT2N0/1M0 cancers, and station 12a for cT1N0/1M0-T2N1M0 cancers, regardless of size and differentiation. The rates of LN metastasis for cT1N0M0 cancers were 0.3% (1 of 396 LNs) at station 6 and 0.8% (1 of 129 LNs) at station 11d. Tumors 4 cm or smaller were associated with a lower risk of LN metastasis compared with tumors 4.1 cm or larger (odds ratio, 2.10; 95% CI, 1.20-3.67; P = .009), and well-differentiated tumors were associated with lower risk of LN metastasis compared with poorly differentiated tumors (odds ratio, 2.88; 95% CI, 1.45-5.73; P = .002). CONCLUSIONS AND RELEVANCE These findings suggest that MSG with dissection of stations 1, 3, 4sb, 4d, 7, 8a, 9, 11p, and 12a could be done for HB and MB cT1N0/1M0 gastric cancers 4 cm or smaller and well-differentiated cT2N0/1M0 cancers.

J Gastric Cancer 2020; 20:277-289.

Abstract
Purpose To evaluate the feasibility and safety of intracorporeal overlapping gastrogastrostomy between the proximal anterior wall and antrum posterior wall (PAAP; PAAP anastomosis) of the stomach in minimally invasive pylorus-preserving gastrectomy (PPG) for early gastric cancer (EGC). Materials and Methods From December 2016 to December 2019, 17 patients underwent minimally invasive PPG with PAAP anastomosis for EGC in the high body and posterior wall of the stomach. Intraoperative gastroscopy was performed with the rotation maneuver during proximal transection. A longer antral cuff (>4-5 cm) was created for PAAP than for conventional PPG (≤3 cm) at the point where a safe distal margin and good vascular perfusion were secured. Because the posterior wall of the proximal remnant stomach was insufficient for intracorporeal anastomosis, the anterior wall was used to create an overlapping anastomosis with the posterior wall of the remnant antrum. The surgical and oncological outcomes were analyzed, and the stomach volume was measured in patients who completed the 6-month follow-up. The results were compared to those after conventional PPG (n=11 each). Results PAAP anastomosis was successfully performed in 17 patients. The proximal and distal resection margins were 2.4±1.9 cm and 4.0±2.6 cm, respectively. No postoperative complications were observed during the 1-year follow-up esophagogastroduodenoscopy (n=10). The postoperative remnant stomach (n=11) was significantly larger with PAAP than with conventional PPG (225.6±118.3 vs. 99.1±63.2 mL; P=0.001). The stomach length from the anastomosis to the pylorus was 4.9±2.4 cm after PAAP. Conclusions PAAP anastomosis is a feasible alternative for intracorporeal anastomosis in minimally invasive PPG for highly posteriorly located EGC.

Left Dorsal Wall Anastomosis Compared with Parallel-Line Anastomosis for Intracorporeal Overlap Esophagojejunostomy during Laparoscopic Total Gastrectomy. THE JOURNAL OF MINIMALLY INVASIVE SURGERY 2020; 23:17-21. [PMID: 35600735 PMCID: PMC9012208 DOI: 10.7602/jmis.2020.23.1.17] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/16/2019] [Revised: 10/01/2019] [Accepted: 10/14/2019] [Indexed: 12/05/2022]
Abstract
Purpose This study evaluated the safety and efficacy of totally laparoscopic total gastrectomy (TLTG) with esophagojejunostomy by comparing left dorsal wall anastomosis (LDA) with parallel-line anastomosis (PA) methods. Methods We retrospectively reviewed 28 patients who underwent laparoscopic total gastrectomy (LTG) for gastric cancer from January 2017 to September 2018. The patients were divided into two groups according to type of operation: 15 patients underwent PA and 13 underwent LDA. Clinicopathologic characteristics and surgical outcomes in the two groups were compared and analyzed. Results Surgical outcomes of estimated blood loss, operation time, and length of postoperative stay were similar between the two groups. In addition, there was no statistical difference in total operation time (186.5±37.0 min vs. 209.0±36.9 min, p=0.121) between the two groups. However, compared with the PA group, the LDA group required fewer additional stitches for reinforcement (p=0.002). Conclusion Intracorporeal reconstruction of esophagojejunostomy using an LDA method may be a feasible and easy technique for TLTG compared with the PA method. Additional studies with larger sample sizes are needed to further support these results.

Abstract
In addition to the popularity of laparoscopic gastrectomy (LG), many reconstructive procedures after LG have been reported. Surgical resection and lymphatic dissection determine long-term survival; however, the election of a reconstruction procedure determines the postoperative quality of life for patients with gastric cancer (GC). Presently, no consensus exists regarding the optimal reconstructive procedure. In this review, the current state of digestive tract reconstruction after LG is reviewed. According to the determining influence of the tumor site on the procedures of surgical resection and reconstruction, we divide these reconstruction procedures into three categories consistent with the resection procedures. We focus on the technical tips of every reconstruction procedure and examine the surgical outcomes (length of surgery and blood loss) and postoperative complications (anastomotic leakage and stricture) to facilitate gastrointestinal surgeons to understand the merits and demerits of every reconstruction procedure.

Abstract
BACKGROUND Totally laparoscopic gastrectomy (LG) is preferred over open gastrectomy because it allows safe anastomosis, a small wound, and early bowel recovery. However, esophagojejunostomy (EJS) following laparoscopic total gastrectomy (LTG) remains technically challenging. To popularize LTG, a secure method of reconstruction must be developed. We present a simple and safe technique for intracorporeal EJS following LTG. METHODS Our modified technique for intracorporeal EJS as a part of Roux-en-Y reconstruction following LTG incorporates an isoperistaltic stapled EJS with closure of the entry hole using two unidirectional barbed sutures. First, a side-to-side isoperistaltic EJS is created between the dorsal and left side of the esophagus and the jejunal arm. Second, the opening for the stapler is closed with a two-layer continuous suture using two 15-cm 3-0 V-Loc suture devices. The full-thickness inner layer closure commences from the sides of the staple lines and progresses toward the center of the enterotomy. During suturing, the remaining thread is utilized to apply tension and lift the enterotomy. Once the full-thickness layer closure is complete at the center of the enterotomy, suturing of the second seromuscular layer is started in the forward direction toward each corner to give a crossover-shaped suturing line. RESULTS From February 2012 to October 2017, 27 patients with gastric cancer underwent LTG with intracorporeal stapled EJS as a part of Roux-en-Y reconstruction. All procedures were successfully performed without any intra- or postoperative anastomosis-related complications. No conversion to other procedures was required. The mean suturing time was 19.1 ± 9.5 min. The mean postoperative time to tolerating a liquid diet was 3.3 days, and the mean hospital stay was 12.1 days. CONCLUSIONS We herein report our procedure for intracorporeal EJS using a linear stapler and barbed sutures. This technique is simple and feasible and has acceptable morbidity.

A novel method of intracorporeal end-to-end gastrogastrostomy in laparoscopic pylorus-preserving gastrectomy for early gastric cancer, including a unique anastomotic technique: piercing the stomach with a linear stapler. Surg Endosc 2018; 32:4337-4343. [PMID: 29785457 DOI: 10.1007/s00464-018-6237-6] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2018] [Accepted: 05/09/2018] [Indexed: 12/14/2022]
Abstract
BACKGROUND Delta-shaped anastomosis is usually applied for an intracorporeal gastrogastrostomy in totally laparoscopic pylorus-preserving gastrectomy (TLPPG). However, the remnant stomach is slightly twisted around the anastomosis because it connects in side-to-side fashion. To realize an intracorporeal end-to-end gastrogastrostomy using an endoscopic linear stapler, we invented a novel method including a unique anastomotic technique. MATERIALS AND METHODS In this new approach, we first made small gastrotomies at the greater and lesser curvatures of the transected antrum and then pierced it using an endoscopic linear stapler. After the pierced antrum and the proximal remnant stomach were mechanically connected, the gastrotomies and stapling lines were transected using an endoscopic linear stapler, creating an intracorporeal end-to-end gastrogastrostomy. We have named this technique the "piercing method" because piercing the stomach is essential to its implementation. Between October 2015 and June 2017, 26 patients who had clinically early gastric cancer at the middle third of the stomach without clinical evidence of lymph node metastasis underwent TLPPG involving the novel method. RESULTS The 26 patients successfully underwent an intracorporeal mechanical end-to-end gastrogastrostomy by the piercing method. The median operation time of the 26 patients was 272 min (range 209-357 min). With the exception of one gastric stasis, no problems associated with the piercing method were encountered during and after surgery. CONCLUSION The piercing method can safely create an intracorporeal mechanical end-to-end gastrogastrostomy in TLPPG. Piercing the stomach using an endoscopic linear stapler is a new technique for gastrointestinal anastomosis. This method should be considered if the surgical aim is creation of an intracorporeal end-to-end gastrogastrostomy in TLPPG.

Abstract
In 1994, Kitano and colleagues first reported laparoscopy-assisted Billroth I gastrectomy. Since then, laparoscopic gastrectomy (LG) has been associated with earlier patient recovery compared with open surgery, and has gained increasing international acceptance. Japan Society of Endoscopic Surgery biennial surveys confirm the increasing use of laparoscopic procedures for treatment of gastric cancer in Japan. Its thirteenth national survey indicates that of 31,264 patients treated at Japanese institutions in 2015, approximately 9,500 (30.3%) underwent LG, and laparoscopic distal gastrectomy (LDG) was the procedure most commonly performed. Despite evidence supporting the efficacy of LDG for gastric cancer in the short term, however, uncertainty remains concerning the efficacy of LG. Today, phase III randomized control trials on this procedure are ongoing in East Asian countries. Distal gastrectomy (DG) is the most commonly performed mode of resection, and as appropriate surgical techniques need to be acquired by gastric surgeons, here we describe a 'gold standard' method to perform total LDG.

Abstract
The number of early gastric cancer (EGC) cases has been increasing because of improved diagnostic procedures including endoscopy and screening systems. Therefore, function-preserving gastrectomy (FPG) for EGC with the expectation of better quality of life (QOL) after surgery may be increasingly utilized, due to its association with low rate of lymph node metastasis and excellent survival and the possibility of employing less invasive procedures such as laparoscopic gastrectomy in combination. Pylorus-preserving gastrectomy (PPG) with curative intent lymph node dissection is a representative FPG that has been used in EGC, and its superiorities, indications, limitations, and survival benefits have already been reported in several retrospective studies. Laparoscopic proximal gastrectomy (LAPG) has also been employed in EGC of the upper third of the stomach; however, LAPG was found to be associated with major issues in achieving a balance between swallowing and reflux prevention. In patients with EGC in the upper third of the stomach, laparoscopy-assisted subtotal gastrectomy with a preserved, albeit very small, stomach may provide a better QOL and fewer postoperative complications. FPG is recommended as a surgical treatment for EGC if the indication is accurately diagnosed and strictly confirmed; however, these techniques in laparoscopic surgery present technical difficulties to surgeons without a certain degree of skills. Although many retrospective studies revealed the functional benefits or oncological safety with FPG, further prospective studies using large case series are necessary to reveal the value of FPG compared with the conventional procedures.

Abstract
Pylorus-preserving gastrectomy (PPG) is a function-preserving surgery for the treatment of early gastric cancer (EGC), aiming to decrease the complication rate and improve postoperative quality of life. According to the Japanese gastric cancer treatment guidelines, PPG can be performed for cT1N0M0 gastric cancer located in the middle-third of the stomach, at least 4.0 cm away from the pylorus. Although the length of the antral cuff gradually increased, from 1.5 cm during the initial use of the procedure to 3.0 cm currently, its optimal length still remains unclear. Standard procedures for the preservation of pyloric function, infra-pyloric vessels, and hepatic branch of the vagus nerve, make PPG technically more difficult and raise concerns about incomplete lymph node dissection. The short- and long-term oncological and survival outcomes of PPG were comparable to those for distal gastrectomy, but with several advantages such as a lower incidence of dumping syndrome, bile reflux, and gallstone formation, and improved nutritional status. Gastric stasis, a typical complication of PPG, can be effectively treated by balloon dilatation and stent insertion. Robot-assisted pylorus-preserving gastrectomy is feasible for EGC in the middle-third of the stomach in terms of the short-term clinical outcome. However, any benefits over laparoscopy-assisted PPG (LAPPG) from the patient's perspective have not yet been proven. An ongoing Korean multicenter randomized controlled trial (KLASS-04), which compares LAPPG and laparoscopy-assisted distal gastrectomy for EGC in the middle-third of the stomach, may provide more clear evidence about the advantages and oncologic safety of PPG.

Intracorporeal reconstruction after laparoscopic pylorus-preserving gastrectomy for middle-third early gastric cancer: a hybrid technique using linear stapler and manual suturing. Langenbecks Arch Surg 2016; 401:397-402.

Abstract
PURPOSE Laparoscopy-assisted pylorus-preserving gastrectomy has been increasingly reported as a treatment for early gastric cancer located in the middle third of the stomach because of its low invasiveness and preservation of pyloric function. Advantages of a totally laparoscopic approach to distal gastrectomy, including small wound size, minimal invasiveness, and safe anastomosis, have been recently reported. Here, we introduce a new procedure for intracorporeal gastro-gastrostomy combined with totally laparoscopic pylorus-preserving gastrectomy (TLPPG). METHODS The stomach is transected after sufficient lymphadenectomy with preservation of infrapyloric vessels and vagal nerves. The proximal stomach is first transected near the Demel line, and the distal side is transected 4 to 5 cm from the pyloric ring. To create end-to-end gastro-gastrostomy, the posterior wall of the anastomosis is stapled with a linear stapler and the anterior wall is made by manual suturing intracorporeally. We retrospectively assessed the postoperative surgical outcomes via medical records. The primary endpoint in the present study is safety. RESULTS Sixteen patients underwent TLPPG with intracorporeal reconstruction. All procedures were successfully performed without any intraoperative complications. The mean operative time was 275 min, with mean blood loss of 21 g. With the exception of one patient who had gastric stasis, 15 patients were discharged uneventfully between postoperative days 8 and 11. CONCLUSIONS Our novel hybrid technique for totally intracorporeal end-to-end anastomosis was performed safely without mini-laparotomy. This technique requires prospective validation.

Abstract
OBJECTIVE Intracorporeal reconstruction of the digestive tract is technically challenging. The V-Loc 180 wound closure device (Covidien) is a self-anchoring unidirectional barbed suture that obviates the need for knot tying. The aim of this prospective cohort study was to investigate the use of the novel suture in gastrointestinal enterotomy closure. METHODS The subjects comprised patients with malignant disease who were scheduled to undergo laparoscopic gastrectomy with curative intent. The barbed suture was used to close the entry hole for the linear stapler during intracorporeal reconstruction following laparoscopic gastric resection. The primary endpoint was the proportion of patients who developed anastomotic leakage at the site where the barbed suture was applied. RESULTS Between July 2012 and March 2015, 242 patients were enrolled. Of 362 anastomoses, the enterotomy hole at 256 sites was closed using the barbed suture. These 256 sites consisted of 95 gastroduodenostomies, 25 gastrogastrostomies, 13 gastrojejunostomies, 90 jejunojejunostomies, 17 esophagojejunostomies and 16 primary closures of the stomach following local gastric resection. There were no anastomosis-related complications, conversion to usual sutures, mechanical closure of the entry hole and reoperation due to adhesive obstructions or mortality over a median follow-up period of 17.8 months. CONCLUSIONS The use of the unidirectional barbed absorbable suture for gastrointestinal closure is safe and effective in laparoscopic gastrectomy.

Abstract
BACKGROUND Pylorus-preserving gastrectomy (PPG) is sometimes performed as a function-preserving surgery for the treatment of early gastric cancer. The aim of this study was to use an integrated assessment scale for postgastrectomy syndrome to determine the appropriate indicators and optimal methods for PPG. METHODS The Postgastrectomy Syndrome Assessment Study (PGSAS) is a multicenter survey based on an integrated questionnaire (PGSAS-45) consisting of 45 items. Questionnaire responses were retrieved from a total of 2,520 patients, each of whom had undergone one of six different types of gastrectomy procedures; 313 responses from patients who had received PPG were analyzed here. RESULTS The size of the proximal gastric remnant (less than one-quarter, about one-third, or more than one-half of the original size) significantly influenced the change in body weight, the scores for dissatisfaction at the meal, and dissatisfaction for daily life subscale (P = 0.030, P = 0.005, P = 0.034, respectively). The nausea score in patients who underwent hand-sewn anastomosis was significantly lower than in those who underwent anastomosis with a linear stapler (P = 0.006). The scores for diarrhea subscale, increased passage of stools, and sense of foods sticking differed significantly depending on the length of the preserved pyloric cuff (P = 0.047, P = 0.021, P = 0.046, respectively). CONCLUSIONS The results suggest that preservation of a sufficient proximal gastric remnant is recommended when utilizing PPG as function-preserving surgery.

Abstract
INTRODUCTION The feasibility, safety, and improved quality of postoperative life following laparoscopy-assisted pylorus-preserving gastrectomy (LAPPG) with a hand-sewn anastomosis via a mini-laparotomy for early gastric cancer (EGC) have been previously established. Here we describe the surgical procedure of totally laparoscopic pylorus-preserving gastrectomy (TLPPG) using an intracorporeal delta-shaped anastomosis technique, and the short-term surgical outcomes of 60 patients with EGC in the middle stomach are reported. METHODS After lymphadenectomy and mobilization of the stomach, intraoperative gastroscopy was performed in order to verify the location of the tumor, and then the distal and proximal transecting lines were established, 5 cm from the pyloric ring and just proximal to Demel's line, respectively. Following transection of the stomach, a delta-shaped intracorporeal gastrogastrostomy was made with linear staplers. RESULTS There were no intraoperative complications or conversions to open surgery. Mean operation time and blood loss were 259 min and 28 mL, respectively. Twelve patients (20.0%) experienced postoperative complications classified as grade II using the Clavien-Dindo classification, with the most frequent complication being gastric stasis (6 cases, 10.0 %). The incidence of severe complications classified as grade III or above was 1.7%; only one patient required reoperation and intensive care due to postoperative intraabdominal bleeding and subsequent multiple organ failure. CONCLUSION TLPPG with an intracorporeal delta-shaped anastomosis was found to be a safe procedure, although it tended to require a longer operating time than the well-established LAPPG with a hand-sewn gastrogastrostomy.

Abstract
The number of early gastric cancer (EGC) cases has been increasing because of improved diagnostic procedures. Applications of function-preserving gastric cancer surgery may therefore also be increasing because of its low incidence of lymph node metastasis, excellent survival rates, and the possibility of less-invasive procedures such as laparoscopic gastrectomy being used in combination. Pylorus-preserving gastrectomy (PPG) with radical lymph node dissection is one such function-preserving procedure that has been applied for EGC, with the indications, limitations, and survival benefits of PPG already reported in several retrospective studies. Laparoscopy-assisted proximal gastrectomy has also been applied for EGC of the upper third of the stomach, although this procedure can be associated with the 2 major problems of reflux esophagitis and carcinoma arising in the gastric stump. In the patient with EGC in the upper third of the stomach, laparoscopy-assisted subtotal gastrectomy with a preserved very small stomach may provide a better quality of life for the patients and fewer postoperative complications. Finally, the laparoscopy endoscopy cooperative surgery procedure combines endoscopic submucosal dissection with laparoscopic gastric wall resection, which prevents excessive resection and deformation of the stomach after surgery and was recently applied for EGC cases without possibility of lymph node metastasis. Function-preserving laparoscopic gastrectomy is recommended for the treatment of EGC if the indication followed by accurate diagnosis is strictly confirmed. Preservation of remnant stomach sometimes causes severe postoperative dysfunctions such as delayed gastric retention in PPG, esophageal reflux in PG, and gastric stump carcinoma in the remnant stomach. Moreover, these techniques present technical difficulties to the surgeon. Although many retrospective studies showed the functional benefit or oncological safety of function-preserving gastrectomy, further prospective studies using large case series are necessary.

Abstract
Background Laparoscopic gastrectomy has recently been gaining popularity as a treatment for cancer; however, little is known about the benefits of intracorporeal (IC) gastrointestinal anastomosis with pure laparoscopic distal gastrectomy (LDG) compared with extracorporeal (EC) anastomosis with laparoscopy-assisted distal gastrectomy (LADG). Methods Between June 2000 and December 2011, we assessed 449 consecutive patients with early-stage gastric cancer who underwent LDG. The patients were classified into three groups according to the method of reconstruction LADG followed by EC hand-sewn anastomosis (LADG + EC) (n = 73), using any of three anastomosis methods (Billroth-I (B-I), Billroth-II (B-II) or Roux-en-Y (R-Y); LDG followed by IC B-I anastomosis (LDG + B-I) (n = 248); or LDG followed by IC R-Y anastomosis (LDG + R-Y) (n = 128)). The analyzed parameters included patient and tumor characteristics, operation details, and post-operative outcomes. Results The tumor location was significantly more proximal in the LDG + R-Y group than in the LDG + B-I group (P < 0.01). Mean operation time, intra-operative blood loss, and the length of post-operative hospital stay were all shortest in the LDG + B-I group (P < 0.05). Regarding post-operative morbidities, anastomosis-related complications occurred significantly less frequently in with the LDG + B-I group than in the LADG + EC group (P < 0.01), whereas there were no differences in the other parameters of patients’ characteristics. Conclusions Intracorporeal mechanical anastomosis by either the B-I or R-Y method following LDG has several advantages over at the LADG + EC, including small wound size, reduced invasiveness, and safe anastomosis. Although additional randomized control studies are warranted to confirm these findings, we consider that pure LDG is a useful technique for patients with early gastric cancer.

Abstract
BACKGROUND Recently, laparoscopic-assisted distal gastrectomy (LADG) has become popular for the treatment of early gastric cancer. Furthermore, the use of totally laparoscopic gastrectomy (TLG), a more difficult procedure than LADG, has been increasing in Japan. Laparoscopic-assisted distal gastrectomy is currently performed more frequently than laparoscopic distal gastrectomy (LDG) in hospitals in Japan. METHOD Reconstruction after LDG is commonly performed extra-abdominally and lymph node dissection of the lesser curvature is performed at the same time. We have developed a new method of intra-abdominal lymph node dissection for the lesser curvature. RESULTS Our technique showed positive results, is easy to perform, and is reasonable in terms of general oncology theory. CONCLUSION In oncological therapy, this technique could be a valuable surgical option for totally laparoscopic surgery.

Abstract
PURPOSE This study investigated the postoperative quality of life (QOL) after laparoscopy-assisted pylorus-preserving gastrectomy (LAPPG) in comparison to laparoscopy-assisted distal gastrectomy (LADG). METHODS Twenty-one patients with early-stage gastric cancer underwent minimally invasive LADG (n = 12) or LAPPG (n = 9). Demographic and cancer-related data were obtained retrospectively from medical records. QOL was assessed using a 13-item questionnaire and the Japanese edition of the Gastrointestinal Symptom Rating Scale, which were mailed to patients twice postoperatively. Body weight and hemoglobin levels were measured at the same time. RESULTS Early upper abdominal pain was rated as significantly worse with LAPPG than with LADG at the first checkup (1.4 vs. 1.0, P = 0.02) but not at the second checkup (1.3 vs. 1.0, P = 0.07). There was a trend toward less body weight loss in the LAPPG patients in comparison to the LADG patients. The serum hemoglobin levels of LAPPG patients at the second checkup showed significantly higher than LADG patients (13.3 vs. 11.6 g/dL, P < 0.05). CONCLUSIONS LAPPG and LADG produce similar QOL in patients. Trends toward less body weight loss and improved anemia in LAPPG patients may therefore become more pronounced in future studies that have adequate number of the patients and longer follow-up periods.

Comparative analysis of station-specific lymph node yield in laparoscopic and open distal gastrectomy for early gastric cancer. Surg Laparosc Endosc Percutan Tech 2012; 21:424-8.

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.

Intracorporeal Anastomosis Using Linear Stapler in Laparoscopic Distal Gastrectomy: Comparison between Gastroduodenostomy and Gastrojejunostomy. J Gastric Cancer 2011; 11:212-8.

Abstract
Purpose Intracorporeal anastomosis during laparoscopic gastrectomy is becoming increasingly prevalent. However, selection of the anastomosis method after laparoscopic distal gastrectomy is equivocal because of a lack of technical feasibility and safety. We compared intracorporeal gastroduodenostomy with gastrojejunostomy using linear staplers to evaluate the technical feasibility and safety of intracorporeal anastomoses as well as its' minimally invasiveness. Materials and Methods Retrospective analyses of a prospectively collected database for gastric cancer revealed 47 gastric cancer patients who underwent laparoscopic distal gastrectomy with either intracorporeal gastroduodenostomy or gastrojejunostomy from March 2011 to June 2011. Perioperative outcomes such as operation time, postoperative complication, and hospital stay were compared according to the type of anastomosis. Postoperative inflammatory response was also compared between the two groups using white blood cell count and high sensitivity C-reactive protein. Results Among the 47 patients, 26 patients received gastroduodenostomy, whereas 21 patients received gastrojejunostomy without open conversion or additional mini-laparotomy incision. There was no difference in mean operation time, blood loss, and length of postoperative hospital stays. There was no statistically significant difference in postoperative complication or mortality between two groups. However, significantly more staplers were used for gastroduodenostomy than for gastrojejunostomy (n=6) than for gastroduodenostomy and (n=5). Conclusions Intracorporeal anastomosis during laparoscopic gastrectomy using linear stapler, either gastroduodenostomy or gastrojejunostomy, shows comparable and acceptable early postoperative outcomes and are safe and feasible. Therefore, surgeons may choose either anastomosis method as long as oncological safety is guaranteed.
