Trans-pacific multicenter collaborative study of minimally invasive proximal versus total gastrectomy for proximal gastric and gastroesophageal junction cancers. BMC Surg 2023; 23:262. [PMID: 37653380 PMCID: PMC10472658 DOI: 10.1186/s12893-023-02163-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2022] [Accepted: 08/16/2023] [Indexed: 09/02/2023] Open
Abstract
BACKGROUND The current standard operation for proximal gastric and gastroesophageal junction (P/GEJ) cancers with limited esophageal extension is total gastrectomy (TG). TG is associated with impaired appetite and weight loss due to the loss of gastric functions such as production of ghrelin and with anemia due to intrinsic factor loss and vitamin B12 malabsorption. Theoretically, proximal gastrectomy (PG) can mitigate these problems by preserving gastric function. However, PG with direct esophagogastric reconstruction is associated with severe postoperative reflux, delayed gastric emptying, and poor quality of life (QoL). Minimally invasive PG (MIPG) with antireflux techniques has been increasingly performed by experts but is technically demanding owing to its complexity. Moreover, the actual advantages of MIPG over minimally invasive TG (MITG) with regards to postoperative QoL are unknown. Our overall objective of this study is to determine the short-term QoL benefits of MIPG. Our central hypotheses are that MIPG is safe and that patients have improved appetite after MIPG with effective antireflux techniques, which leads to an overall QoL improvement when compared with MITG. METHODS Enrollment of a total of 60 patients in this prospective survey-collection study is expected. Procedures (MITG versus MIPG, antireflux techniques for MIPG [double-tract reconstruction versus the double-flap technique]) will be chosen based on surgeon and/or patient preference. Randomization is not considered feasible because patients often have strong preferences regarding MITG and MIPG. The primary outcome is appetite level (reported on a 0-10 scale) at 3 months after surgery. With an expected 30 patients per cohort (MITG versus MIPG), this study will have 80% power to detect a one-point difference in appetite level. Patient-reported outcomes will be longitudinally collected (including questions about appetite and reflux), and specific QoL items, body weight, body mass index and ghrelin, albumin, and hemoglobin levels will be compared. DISCUSSION Surgeons from the US, Japan, and South Korea formed this collaboration with the agreement that the surgical approach to P/GEJ cancers is an internationally important but controversial topic that requires immediate action. At the completion of the proposed research, our expected outcome is the establishment of the benefit and safety of MIPG. TRIAL REGISTRATION This trial was registered with Clinical Trials Reporting Program Registration under the registration number NCI-2022-00267 on January 11, 2022, as well as with ClinicalTrials.gov under the registration number NCT05205343 on January 11, 2022.

Abstract
Background Appropriate gastrointestinal reconstruction after proximal gastrectomy can effectively reduce the incidence of postoperative complications in patients with proximal early gastric cancer. However, there is still great controversy about the choice of digestive tract reconstruction after proximal gastrectomy, and there is no clinical consensus on the choice of digestive tract reconstruction after proximal gastrectomy. Currently, there is a lack of large-sample, prospective, randomized controlled studies to compare the efficacy of Kamikawa, double-tract reconstruction, and tube-like stomach reconstruction after proximal gastrectomy. Methods/design This study will investigate the efficacy of three reconstruction methods after proximal gastrectomy in a prospective, multicenter, randomized controlled trial, which will enroll 180 patients with proximal early gastric cancer. Patients will be randomly divided into three groups: Group A (Kamikawa, n = 60), Group B (double-tract reconstruction, n = 60), and Group C (tube-like stomach, n = 60). The general information, past medical history, laboratory findings, imaging findings, and surgical procedures of the patients will be recorded and analyzed. The incidence of reflux esophagitis will be recorded as the primary endpoint. The incidence of anastomotic leakage, anastomotic stenosis, operative time and intraoperative blood loss will be recorded as secondary endpoints. Discussion This study will establish a large-sample, prospective, randomized controlled trial to compare the efficacy of Kamikawa, double-tract reconstruction, and tube-like stomach reconstruction after proximal gastrectomy. Trial registration This study was approved by the Chinese Clinical Trial Registry and registered on April 30, 2021. The registration number is ChiCTR2100045975.

Abstract
BACKGROUND Minimally invasive surgery is now a standard treatment for gastric cancer. Many retrospective studies have reported that robotic gastrectomy is safe and feasible, with similar short- and long-term outcomes as laparoscopic gastrectomy. However, no studies have reported the details of surgical and survival outcomes for robotic gastrectomy. This study aimed to evaluate the surgical trends and techniques of robotic gastrectomy and analyze the surgical outcomes of 2000 consecutive patients with gastric cancer who underwent robotic gastrectomy over 14 years. METHODS Between July 2005 and January 2019, 2000 consecutive robotic gastrectomies were performed. We evaluated short- and long-term outcomes as well as surgical trends after robotic gastrectomy. RESULTS There were 1,560 subtotal gastrectomies (78%), 324 total gastrectomies (16.2%), 83 proximal gastrectomies (4.2%), and 33 completion total gastrectomies (1.7%). The rates of major complications and mortality were 3.1% and 0.3%, respectively. In a subgroup analysis, there were no significant differences in the rate of complications over time (P = 0.696). Five-year overall survival rates were 97.6% for stage I, 91.9% for stage II, and 69.2% for stage III, with a total recurrence rate of 5.3%. Since its adoption in 2005, the proportion of robotic gastrectomies, as well as technically demanding procedures have increased over time. CONCLUSIONS Our 14 years' experience of 2000 robotic gastrectomies has shown the proportion, as well as the number of robotic gastrectomies, have tended to increase and trends toward to technically demanding procedures. Outcomes of robotic gastrectomy appear safe and feasible with acceptable short- and long-term outcomes.

Abstract
The number of people with gastric cardia and distal oesophageal cancers has increased in the last five years. The surgical treatment method of choice is proximal gastrectomy, with an option being reconstruction of the gastrointestinal tract. There are many reconstruction techniques for anastomosis of the oesophagus and distal parts of the digestive tract. However, all can result in complications. This systematic review aims to identify the efficacy of the double-tract reconstruction method after gastric resection. Different operative techniques for gastric reconstruction have been included in this review. The double-tract reconstruction method, which is gaining popularity among surgeons in Asia and Europe, is a promising technique that improves the early and late results of surgical treatment. This method is associated with low complications related to gastroesophageal reflux disease and dysphagia. Double-tract reconstruction is a promising method for the treatment of patients with esofagocardial gastric cancer. However, further studies are required on the long-term complications and side effects.

Adverse Prognostic Impact of Postoperative Complications After Gastrectomy for Patients With Stage II/III Gastric Cancer: Analysis of Prospectively Collected Real-World Data. Front Oncol 2021; 11:611510. [PMID: 33996540 PMCID: PMC8116792 DOI: 10.3389/fonc.2021.611510] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2020] [Accepted: 04/13/2021] [Indexed: 12/23/2022] Open
Abstract
Background The impact of postoperative complications on the prognosis of gastric cancer remains controversial. This study aimed to evaluate the relationship between postoperative complications and long-term survival in patients undergoing gastrectomy for stage II/III gastric cancer. Methods Some 939 patients underwent curative gastrectomy for stage II/III gastric cancer were identified from real-world data prospectively collected between 2013 and 2015. We divided patients according to the presence of serious complications, specifically, Clavien-Dindo grade III or higher complications or those causing a hospital stay of 15 days or longer. Results Serious complications occurred in 125 (13.3%) patients. Patients without serious complications (64.3%) completed adjuvant chemotherapy significantly more than patients with serious complications (37.6%; p<0.001). The 5-year overall survival(OS) rate was 58.1% and recurrence-free survival(RFS) rate was 58.1% in patients with serious complications, which were significantly worse than those of patients without serious complications (73.4% and 74.7%, respectively; p<0.001 for both). In stage II, once patients completed adjuvant chemotherapy adequately, the OS and RFS of patients with serious complications did not differ from those without serious complications. However, in stage III, the patients with serious complications showed a worse OS even after completion of adequate adjuvant chemotherapy. Conclusion Serious complications after gastrectomy had a negative impact on the prognosis of stage II/III gastric cancer patients. Serious complications worsen the survival in association with inadequate adjuvant chemotherapy. Efforts to reduce serious complications, as well as support adequate chemotherapy through proper management of serious complications, would improve the prognosis of stage II/III gastric cancer patients.

A novel method for π-shaped esophagojejunostomy and double-tract reconstruction (DTR) as an alternative in totally laparoscopic or robotic proximal gastrectomy for treating upper third proximal early gastric cancer. Updates Surg 2021; 73:597-605. [PMID: 33576931 DOI: 10.1007/s13304-021-00993-w] [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: 07/14/2020] [Accepted: 01/29/2021] [Indexed: 02/07/2023]
Abstract
This study evaluated the impact of a new intracorporeal π-shaped esophagojejunostomy (EJS) and double-tract reconstruction (DTR) in totally laparoscopic and totally robotic proximal gastrectomy (TLPG or TRPG) for treating upper third early gastric cancer (U-EGC) in terms of intraoperative and short-term postoperative outcomes. Early proximal gastric cancer patients were identified based on a prospectively established database. From January 2017 to December 2018, these patients underwent intracorporeal π-shaped EJS and DTR after totally laparoscopic (n = 8) or robotic (n = 4) proximal gastrectomy (PG). We recorded and analyzed the baseline characteristics and surgical outcomes, including postoperative complications for these patients. No severe postoperative complications were observed following the operational procedures. Twelve patients (seven male and five female) diagnosed with cardia cancer (Siewert II and III) were enrolled, of which eight underwent the totally laparoscopic proximal gastrectomy (TLPG), and four underwent the totally robotic proximal gastrectomy (TRPG). The mean operative time, blood loss, day of the start of the diet, and postoperative hospital stay was 235.54 ± 20.79 min, 50.65 ± 35.44 mL, 3.85 ± 0.65 days, and 12.45 ± 3.24 days, respectively. All patients presented with a diagnosis of stage I gastric cancer. The mean number of lymph node dissections and the maximum tumor diameter was 13.91 ± 4.63 and 2.18 ± 0.73 cm, respectively. After the operational procedure, using the iodoethylene contrast reagent, we observed that a large proportion of iodoethylene contrast agents entered the jejunum directly, and a small proportion entered the jejunum through the duodenum. Surgeons followed up with ten patients for more than 12 months and the remaining two patients for more than 24 months. None of the patients showed any signs of anastomotic stenosis or reflux esophagitis or anemia symptoms. This study presents a novel method for π-shaped EJS and DTR as an alternative in TLPG or TRPG for treating proximal early gastric cancer, and it offers better short-term postoperative and intraoperative surgical outcomes.

Postoperative nutritional outcomes and quality of life-related complications of proximal versus total gastrectomy for upper-third early gastric cancer: a meta-analysis. Sci Rep 2020; 10:21460.

Abstract
Although proximal gastrectomy (PG) provides superior nutritional outcomes over total gastrectomy (TG) in upper-third early gastric cancer (EGC), surgeons are reluctant to perform PG due to the high rate of postoperative reflux. This meta-analysis aimed to comprehensively compare operative outcomes, nutritional outcomes, and quality of life-related complications between TG and PG performed with esophagogastrostomy (EG), jejunal interposition, or double-tract reconstruction (DTR) to reduce reflux after PG. After searching PubMed, Embase, Medline, and Web of Science databases, 25 studies comparing PG with TG in upper-third EGC published up to October 2020 were identified. PG with DTR was similar to TG regarding operative outcomes. Patients who underwent PG with DTR had less weight reduction (weighted mean difference [WMD] 4.29; 95% confidence interval [0.51–8.07]), reduced hemoglobin loss (WMD 5.74; [2.56–8.93]), and reduced vitamin B12 supplementation requirement (odds ratio [OR] 0.06; [0.00–0.89]) compared to patients who underwent TG. PG with EG caused more reflux (OR 5.18; [2.03–13.24]) and anastomotic stenosis (OR 3.94; [2.40–6.46]) than TG. However, PG with DTR was similar to TG regarding quality of life-related complications including reflux, anastomotic stenosis, and leakage. Hence, PG with DTR can be recommended for patients with upper-third EGC considering its superior postoperative nutritional outcomes.

Abstract
BACKGROUND The double-tract reconstruction (DTR) could be a preferable option in avoiding the postoperative esophageal reflux and anastomotic stenosis during totally laparoscopic proximal gastrectomy (TLPG). An optimal procedure to achieve the DTR in TLPG remains to be established. METHODS During March 2018 to April 2019, 15 consecutive patients with gastric cancer in the upper third of the stomach underwent intracorporeal DTR after TLPG at our hospital. The intracorporeal esophagojejunostomy (E-J), gastrojejunostomy (G-J) and jejunojejunostomy (J-J) were, respectively, performed using circular staplers by the Self-Pulling and Holding Purse-String Suture Technique, Intraluminal Poke Technique and U-shaped Parallel Purse-string Suture Technique (Technical Tie-Up). Demographic and clinicopathologic characteristics, perioperative details and postoperative outcomes were analyzed. RESULTS The mean operating time was 216.1 ± 18.2 min. Total time for three anastomoses was 49.8 ± 6.1 min, and the time for E-J, G-J, J-J was 22.4 ± 5.0 min, 13 (range 11-16) min, 14.2 ± 2.8 min, respectively. The median proximal and distal resection margins were 2.5 (range 2-4) cm and 6 (range 5-7) cm, respectively, which were all tumor-free in 15 patients. No major complications and mortality occurred. During the median follow-up period of 14 months (range 7 to 20.5 months), there were no postoperative anastomosis-related complications observed, such as anastomotic bleeding, leakage or stenosis. No patients complained the symptoms indicating esophageal reflux and remnant gastritis. CONCLUSIONS Predominant classic circular-stapled double-tract reconstruction is safe, feasible and time-saving in TLPG by the technical tie-up.

Abstract
BACKGROUND Additional studies comparing several reconstruction methods after proximal gastrectomy have been published; of note, it is necessary to update systematic reviews and meta-analysis from the current evidence-based literature. AIM To expand the current knowledge on feasibility and safety, and also to analyze postoperative outcomes of several reconstructive techniques after proximal gastrectomy. METHODS PubMed, Google Scholar, and Medline databases were searched for original studies, and relevant literature published between the years 1966 and 2019 concerning various reconstructive techniques on proximal gastrectomy were selected. The postoperative outcomes and complications of the reconstructive techniques were assessed. Meta-analyses were performed using Rev-Man 5.0. A total of 29 studies investigating postoperative outcomes of double tract reconstruction, jejunal pouch interposition, jejunal interposition, esophagogastrostomy, and double flap reconstruction were finally selected in the quantitative analysis. RESULT Pooled incidences of reflux esophagitis for double tract reconstruction, jejunal pouch interposition, jejunal interposition esophagogastrostomy, and double flap reconstruction were 8.6%, 13.8%, 13.8%, 19.3%, and 8.9% respectively. Meta-analysis showed a decreased length of hospital in the JI group as compared to the JPI group (heterogeneity: Chi2 = 1.34, df = 1 (P = 0.25); I2 = 26%, test for overall effect: Z = 2.22 (P = 0.03). There was also a significant difference between JI and EG in length of hospital stay with heterogeneity: Chi2 = 1.40, df = 3 (P = 0.71); I2 = 0%, test for overall effect: Z = 5.04 (P < 0.00001). Operative time was less in the EG group as compared to the JI group (heterogeneity: Chi2 = 31.09, df = 5 (P < 0.00001); I2 = 84%, test for overall effect: Z = 32.35 (P < 0.00001). CONCLUSION Although current reconstructive techniques present excellent anti-reflux efficacy, the optimal reconstructive method remains to be determined. The double flap reconstruction proved to lower the rate of complication, but the DTR, JI, JPI, and EG groups showed higher incidence of complications in anastomotic leakage, anastomotic stricture, and residual food. In the meta-analysis result, the complications between the JI, JPI, and EG were comparable but the EG group showed to have better postoperative outcomes concerning the operative time, blood loss, and length of hospital stay.

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
Purpose The robotic system for surgery was introduced to gastric cancer surgery in the early 2000s to overcome the shortcomings of laparoscopic surgery. The more recently introduced da Vinci Xi® system offers benefits allowing four-quadrant access, greater range of motion, and easier docking through an overhead boom rotation with laser targeting. We aimed to identify whether the Xi® system provides actual advantages over the Si® system in gastrectomy for gastric cancer by comparing the operative outcomes. Materials and Methods We retrospectively reviewed all patients who underwent robotic gastrectomy as treatment for gastric cancer from March 2016 to March 2017. Patients' demographic data, perioperative information, and operative and pathological outcomes were collected and analyzed. Results A total of 109 patients were included in the Xi® group and 179 in the Si® group. Demographic characteristics were similar in both groups. The mean operative time was 229.9 minutes in the Xi® group and 223.7 minutes in the Si® group. The mean estimated blood loss was 72.7 mL in the Xi® group and 62.1 mL in the Si® group. No patient in the Xi® group was converted to open or laparoscopy, while 3 patients in the Si® group were converted, 2 to open surgery and 1 to laparoscopy, this difference was not statistically significant. Bowel function was resumed 3 days after surgery, while soft diet was initiated 4 days after surgery. Conclusions We found no difference in surgical outcomes after robotic gastrectomy for gastric cancer between the da Vinci Xi® and da Vinci Si® procedures.

Abstract
Background: An increasing amount of attention has been paid to minimally invasive function-preserving gastrectomy, with an increase in incidence of early gastric cancer in the upper stomach. This study aimed to compare oncological outcomes, surgical stress, and nutritional status between robot-assisted proximal gastrectomy (RAPG) and laparoscopy-assisted proximal gastrectomy (LAPG). Methods: Eighty-nine patients were enrolled in this retrospective study between November 2011 and December 2013. Among them, 27 patients underwent RAPG and 62 underwent LAPG. Perioperative parameters, surgical stress, nutritional status, disease-free survival, and overall survival were compared between the 2 groups. Results: Sex, age, and comorbidity were similar in the RAPG and LAPG groups. There were also similar perioperative outcomes regarding operation time, complications, and length of hospital stay between the groups. The reflux esophagitis rates following RAPG and LAPG were 18.5% and 14.5%, respectively (P = .842). However, patients in the RAPG group had less blood loss (P = .024), more harvested lymph nodes (P = .021), and higher costs than those in the LAPG group (P < .001). With regard to surgical stress, no significant differences were observed in C-reactive protein concentrations and white blood cell count on postoperative days 1, 3, and 7 between the groups (Ps > .05). There appeared to be higher hemoglobin levels at 6 months (P = .053) and a higher body mass index at 12 months (P = .056) postoperatively in patients in the RAPG group compared with those in the LAPG group, but this difference was not significant. Similar disease-free survival and overall survival rates were observed between the groups. Conclusions: RAPG could be an alternative to LAPG for patients with early gastric cancer in the upper stomach with comparable oncological safety and nutritional status. Further well-designed, prospective, large-scale studies are needed to validate these results.

Abstract
BACKGROUND Proximal gastrectomy offers theoretical benefits over total gastrectomy in terms of hematologic and nutritional outcomes. However, little evidence confirming these benefits has been reported. The aim of this study was to assess the hematologic and nutritional outcomes of proximal gastrectomy with double-tract reconstruction in comparison to those of total gastrectomy. METHODS We retrospectively analyzed data from 80 patients with stage I gastric cancer who underwent proximal gastrectomy with double-tract reconstruction (n = 38) or total gastrectomy (n = 42) from September 2014 to December 2015. We compared hematologic (including hemoglobin, ferritin, vitamin B12, etc.) and nutritional outcomes [including body mass index (BMI), serum total protein, albumin, total cholesterol, and total lymphocyte count] between the two groups. RESULTS We found no significant differences in changes in hemoglobin (P = 0.250) or cumulative incidence of iron deficiency anemia (P = 0.971) during a median follow-up period of 24 months (range 18-30 months) after surgery. Cumulative incidence of vitamin B12 deficiency also did not differ significantly between the proximal and total gastrectomy groups (P = 0.087). BMI changes from baseline were not significantly different between the two groups (P = 0.591). Likewise, there were no statistically significant differences in nutritional outcomes. CONCLUSIONS Proximal gastrectomy with double-tract reconstruction exhibited similar outcomes in terms of hematologic and nutritional features in comparison to total gastrectomy.

Abstract
BACKGROUND Proximal early gastric cancer is a good indication for totally laparoscopic proximal gastrectomy (TLPG) with double-tract reconstruction (DTR). However, when most of the dietary intake passes through the escape route of the jejunum, the functional benefits of proximal gastrectomy might be similar to those after total gastrectomy. Our DTR procedure was improved for easy passage through the remnant stomach. The purposes of this study were to present a novel technique for intracorporeal DTR using linear staplers after TLPG and to investigate surgical outcomes. METHODS DTR was performed using linear staplers only. A side-to-side jejunogastrostomy with twisting of both the remnant stomach and the anal jejunum was performed for the purpose of passing meals through the remnant stomach (an oblique jejunogastrostomy technique). The ten patients who underwent TLPG with DTR from January 2011 to August 2016 in Hokkaido University Hospital were retrospectively reviewed. Their clinicopathological characteristics and surgical and postoperative outcomes were collected and analyzed. RESULTS The median duration of operation was 285 (range 146-440) min. No patients required blood transfusions. The number of dissected lymph nodes was 32 (range 22-56). There were no intraoperative complications, and no cases were converted to open surgery. All the patients were pT1N0M0 stage IA. No anastomotic leakage or complications were detected. Postoperative gastrography after reconstruction showed that contrast medium flowed mainly to the remnant stomach. The average percentage body weight loss was 14.0 ± 7.1% at 10 months. The average percentage decrease in serum hemoglobin was 5.4 ± 10.4% at 12 months. CONCLUSIONS This novel technique for intracorporeal DTR provided a considerable advantage by the passage of dietary intake to the remnant stomach after LPG.
