Totally laparoscopic versus laparoscopy-assisted distal gastrectomy: the KLASS-07, a randomized controlled trial.

Strong evidence is lacking as no confirmatory randomized controlled trials (RCTs) have compared the efficacy of totally laparoscopic distal gastrectomy (TLDG) with laparoscopy-assisted distal gastrectomy (LADG). We performed an RCT to confirm if TLDG is different from LADG. The XXXXX trial is a multicentre, open-label, parallel-group, phase III, RCT of 442 patients with clinical stage I gastric cancer. Patients were enrolled from 21 cancer care centers in South Korea between January 2018 and September 2020 and randomized to undergo TLDG or LADG using blocked randomization with a 1:1 allocation ratio, stratified by the participating investigators. Patients were treated through R0 resections by TLDG or LADG as the full analysis set of the XXXXX trial. The primary endpoint was morbidity within postoperative day 30, and the secondary endpoint was QoL for 1 year. This trial is registered at ClinicalTrials.gov (NCT XXXXXXXX). 442 patients were randomized (222 to TLDG, 220 to LADG), and 422 patients were included in the pure analysis (213 and 209, respectively). The overall complication rate did not differ between the two groups (TLDG vs. LADG: 12.2% vs. 17.2%). However, TLDG provided less postoperative ileus and pulmonary complications than LADG (0.9% vs. 5.7%, P=0.006; and 0.5% vs. 4.3%, P=0.035, respectively). The QoL was better after TLDG than after LADG regarding emotional functioning at 6 months, pain at 3 months, anxiety at 3 and 6 months, and body image at 3 and 6 months (all P<0.05). However, these QoL differences were resolved at 1 year. The XXXXX trial confirmed that TLDG is not different from LADG in terms of postoperative complication but has advantages to reduce ileus and pulmonary complications. TLDG can be a good option to offer better QoL in terms of pain, body image, emotion, and anxiety at 3-6 months.

Conversion surgery for gastric remnant cancer with liver metastasis after nivolumab combination chemotherapy achieving pathological complete response: a case report and literature review.

Nivolumab combination chemotherapy has recently emerged as a potential first-line treatment for patients with unresectable or metastatic gastric cancer (GC). Further research has indicated that R0 resection by conversion surgery could be an effective treatment strategy to improve overall survival. However, there have been limited reports on the successful application of conversion surgery following combination chemotherapy achieving pathological complete response (pCR) in cases of advanced gastric remnant cancer with liver metastasis. Here, we present a case of long-term survival in a patient who underwent this treatment. A 54-year-old man was initially referred to our department for treatment of stage III (cT3N1M0) gastric cancer where he underwent laparoscopic distal gastrectomy and D2 lymph node dissection. After a year of uneventful follow-up, the patient was diagnosed with a tumor in the gastric remnant combined with liver metastasis, resulting in a diagnosis of stage IV (cT3N0M1) gastric remnant cancer. Subsequently, the patient was treated with four cycles of TS-1, Oxaliplatin, and Nivolumab as the first-line regimen. Remarkably, both the remnant tumor and liver metastasis exhibited significant shrinkage, and no new lesions were found. Given this response, conversion surgery was performed to achieve complete resection of the remnant gastric cancer and liver metastasis, followed by laparoscopic remnant gastrectomy and partial hepatectomy. Pathological examination revealed the absence of residual carcinoma cells and lymph node metastases. Postoperatively, the patient was treated with adjuvant chemotherapy with S-1 for 1 year, and survived without recurrence for 18months after conversion surgery. Nivolumab combination chemotherapy shows promise as a clinically beneficial treatment approach for gastric remnant cancer with liver metastasis, particularly when pCR can be achieved following conversion surgery.

Short-Term Outcomes Analysis Comparing Open, Laparoscopic, Laparoscopic-Assisted, and Robotic Distal Gastrectomy for Locally Advanced Gastric Cancer: A Randomized Trials Network Analysis.

Minimally invasive surgery for the treatment of locally advanced gastric cancer (AGC) is debated. The aim of this study was to execute a comprehensive assessment of principal surgical treatments for resectable distal gastric cancer. Systematic review and randomized controlled trials (RCTs) network meta-analysis. Open (Op-DG), laparoscopic-assisted (LapAs-DG), totally laparoscopic (Lap-DG), and robotic distal gastrectomy (Rob-DG) were compared. Pooled effect-size measures were the risk ratio (RR), the weighted mean difference (WMD), and the 95% credible intervals (CrIs). Ten RCTs (3823 patients) were included. Overall, 1012 (26.5%) underwent Lap-DG, 902 (23.6%) LapAs-DG, 1768 (46.2%) Op-DG, and 141 (3.7%) Rob-DG. Anastomotic leak, severe complications (Clavien-Dindo > 3), and in-hospital mortality were comparable. No differences were observed for reoperation rate, pulmonary complications, postoperative bleeding requiring transfusion, surgical-site infection, cardiovascular complications, number of harvested lymph nodes, and tumor-free resection margins. Compared to Op-DG, Lap-DG and LapAs-DG showed a significantly reduced intraoperative blood loss with a trend toward shorter time to first flatus and reduced length of stay. LapAs-DG, Lap-DG, and Rob-DG performed in referral centers by dedicated surgeons have comparable short-term outcomes to Op-DG for locally AGC.

Ectopic bile duct concomitant with gastric ulcer hemorrhage: report of a case

BackgroundAn ectopic bile duct opening into the stomach is a rare congenital anomaly of the biliary system, and thus, there are few case reports with gastric ulcer hemorrhage. Herein, we presented a case of ectopic bile duct concomitant with gastric ulcer hemorrhage.Case presentationA 75-year-old woman was referred to our hospital because she repeatedly vomited blood and had melena. Endoscopic hemostasis was attempted for hemorrhage from a gastric ulcer located on the anterior wall of the antrum. However, the bleeding was difficult to stop, and a laparoscopic distal gastrectomy was performed. Her postoperative course was uneventful. Pathological examination revealed that the bleeding point was an ectopic bile duct. In retrospect, an annual endoscopy performed at her family clinic had revealed a bulge in the same portion of the stomach. Exposure to bile acids from an ectopic bile duct opening can cause gastric mucosal damage and ulceration.ConclusionsEctopic bile ducts opening into the stomach can cause gastric ulcer and hemorrhage. Hemorrhage from a submucosal ridge with ulcer in the stomach may be rarely related to the presence of ectopic bile ducts.

Robotic vs. laparoscopic distal gastrectomy for gastric cancer: A propensity score-matched retrospective comparative study at a single institution

BackgroundAlthough robotic surgery is becoming more widespread worldwide, it is still in its infancy. This study aimed to confirm the safety and feasibility of the induction of robotic-assisted gastric surgery at a local hospital. MethodsFor five years, between 2016 and 2020, 42 laparoscopic and 71 robotic distal gastrectomies were performed at the same institution. Patients diagnosed with gastric cancer were retrieved from the database. Propensity score matching was performed based on covariates such as Age, Sex, BMI, the American Society of Anesthesiologists Physical Status, Tumor Location, pT, and pN. Clinicopathological characteristics, surgical performance, postoperative outcomes, and pathological data were retrospectively collected and compared by the Chi-square test, the Fisher's exact test, the Student's t-test, and the Mann–Whitney U test. ResultsBillroth II reconstruction was often selected for the robotic group more than the laparoscopic group (59.4% and 15.6%, respectively). In addition, the number of lymph nodes harvested after D2 dissection tended to be more significant in the robotic group than in the laparoscopic group (52.1 ± 7.6 and 29.1 ± 3.7, respectively; p = 0.00934). The mean operative time was 271.4 ± 10.5 min for the robotic group and 220.8 ± 12.3 min for the laparoscopic group (p = 0.00005). There were no differences in short-term clinical outcomes between the two groups. ConclusionsAlthough a single-center, small comparative study, the results showed that the robotic surgery group was not inferior to the laparoscopic group in feasibility and safety. Moreover, robotic surgery enables harvesting a higher number of lymph nodes, which may be more advantageous than laparoscopic surgery. This study also showed that as the surgeon gains experience with robotic surgery, its operative time becomes significantly shorter.

Higher incidence of cholelithiasis with Roux-en-Y reconstruction compared with Billroth-I after laparoscopic distal gastrectomy for gastric cancer: a retrospective cohort study.

Cholelithiasis occurs often after gastrectomy. However, no consensus has been established regarding the difference in the incidence of postgastrectomy cholelithiasis with different reconstruction methods. In this study, we examined the frequency of cholelithiasis after two major reconstruction methods, namely Billroth-I (B-I) and Roux-en-Y (R-Y) following laparoscopic distal gastrectomy (LDG) for gastric cancer. Among 696 gastric cancer patients who underwent LDG between April 2000 and March 2017, after applying the exclusion criteria, 284 patients who underwent B-I and 310 who underwent R-Y were examined retrospectively. The estimated incidence of cholelithiasis was compared between the methods, and factors associated with the development of cholelithiasis in the gallbladder and/or common bile duct were investigated. During the median follow-up of 61.2months, 52 patients (8.8%) developed cholelithiasis postgastrectomy; 12 patients (4.2%) after B-I and 40 (12.9%) after R-Y (p = 0.0002). Among them, choledocholithiasis was more frequent in patients who underwent R-Y (n = 11, 27.5%) vs. B-I (n = 1, 8.3%) (p = 0.0056). Univariate and multivariate analyses revealed that male sex, body mass index > 22.5kg/m2, and R-Y reconstruction were significant predictors of the development of postLDG cholelithiasis. Regarding cholelithiasis development, B-I reconstruction should be preferred whenever possible during distal gastrectomy.

Impact of treatment guidelines and pivotal clinical trial results on a surgeon's decision regarding treatment for gastric cancer: a retrospective cohort study using the National Clinical Database.

The present study evaluated the impact of clinical guidelines for gastric cancer surgery on surgeons' choice of procedure in real-world practice. We focused on the 2014 guideline revision recommending laparoscopic surgery and the evidence concerning splenectomy for prophylactic lymphadenectomy reported in 2015 using the National Clinical Database, which is the most comprehensive database in Japan. We investigated the monthly percentages of laparoscopic distal gastrectomies performed for stage I gastric cancer (LDG%) and splenectomies performed during total gastrectomy for advanced cancer (TGS%) between 2014 and 2017. We evaluated the descriptive statistics of the time-series changes in the LDG%, TGS%, and annual trends of outcomes. In total, 124,787 patients were enrolled. The mean LDG% and TGS% were 69.8% and 9.2%, respectively. The LDG% and TGS% were 66.4% and 16.7%, respectively, in January 2014 and 73.1% and 5.9%, respectively, in December 2017. LDG% consistently increased, and TGS% showed a consistent downward trend throughout the observation period. There was no significant change in this trend after the publication of the guideline recommendations or clinical trial results. No significant changes in surgical procedures were observed after publication of the guidelines or results of clinical trials.

Preoperative evaluation to determine the difficulty of No. 6 lymphadenectomy in laparoscopic gastrectomy

BackgroundLaparoscopic gastrectomy (LG) requires a long learning curve because of the complicated surgical procedures. Infrapyloric (No. 6) lymph node dissection (LND) is one of the difficult procedures in LG, especially for trainees. This study investigated the impact of the prediction of the difficulty of No. 6 LND.MethodsWe retrospectively reviewed the preoperative computed tomography (CT) images and individual operative video records of 57 patients who underwent LG with No. 6 LND to define and predict the No. 6 LND difficulty. To evaluate whether prediction of the difficulty of No. 6 LND could improve surgical outcomes, 48 patients who underwent laparoscopic distal gastrectomy were assessed (30 patients without prediction by a qualified surgeon and 18 patients with prediction by a trainee).ResultsThe anatomical characteristic that LND required > 2 cm of dissection along the right gastroepiploic vein was defined as difficulty of No. 6 LND. Of the 57 LG patients, difficulty was identified intraoperatively in 21 patients (36.8%). Among the several evaluated anatomical parameters, the length between the right gastroepiploic vein and the right gastroepiploic artery in the maximum intensity projection in contrast-enhanced CT images was significantly correlated with the intraoperative difficulty of No. 6 LND (p < 0.0001). Surgical outcomes, namely intraoperative minor bleeding, postoperative pancreatic fistula, and drain amylase concentration were not significantly different between LG performed by a trainee with prediction compared with that by a specialist without prediction.ConclusionsPreoperative evaluation of the difficulty of No. 6 LND is useful for trainees, to improve surgical outcomes.

Top Gastric Cancer Articles from 2022 and 2023 to Inform Your Cancer Practice.

The multimodality management of patients with gastroesophageal cancers is rapidly evolving, with the introduction of new therapies against potential molecular targets paving the way to personalized medicine for patients with both resectable and metastatic disease. Over the past 2years, several important studies evaluating these new targeted therapies, as well as minimally invasive surgical approaches to gastric cancer, have been published. This review article summarizes the top studies published in gastric cancer over the past 2years that are fundamentally changing our practice approach to gastric cancer patients. First, the long-term safety and efficacy of laparoscopic distal gastrectomy as compared with open gastrectomy for locally advanced gastric cancer was confirmed with the publication of the 5-year outcomes of the CLASS-01 and KLASS-02 randomized clinical trials. In addition, several important studies of perioperative immunotherapy for patients with resectable gastric or gastroesophageal junction cancers are ongoing, and in 2022, an interim analysis of the DANTE trial and the final results of the GERCOR NEONIPIGA study were reported. Lastly, the KEYNOTE-859 and SPOTLIGHT trials address an unmet need for additional targeted therapies for patients with previously untreated, human epidermal growth factor receptor-2 (HER2)-negative, unresectable or metastatic gastroesophageal cancers, incorporating immune checkpoint inhibitors and targeting Claudin-18 isoform 2 (CLDN18.2) with the monoclonal antibody zolbetuximab, respectively. This article summarizes the findings and implications of several important studies published over the past 2years that are fundamentally changing the way we treat patients with gastroesophageal cancer.

Investigation of the impact of COVID-19 on postoperative outcomes using a nationwide Japanese database of patients undergoing laparoscopic distal gastrectomy and low anterior resection for gastric cancer and rectal cancer.

The COVID-19 outbreak made conventional medical care impossible, forcing changes in both healthcare providers and patients. In Japan, COVID-19 infection began spreading in earnest in 2020 and exploded in 2021. There was concern that the medical impact of COVID-19 in 2021 would differ from that in 2020. We aimed to clarify the impact of COVID-19 on mortality and anastomotic leakage in laparoscopic surgery for gastric cancer and rectal cancer in Japan using the National Clinical Database (NCD). We collected data from patients who underwent laparoscopic distal gastrectomy (LDG) and laparoscopic low anterior resection (LLAR) from January 2018 to December 2021 from the NCD, a web-based surgical registration system in Japan. The number of surgical cases, monthly incidence of mortality and morbidity (anastomotic leakage), standardized mortality ratio (SMR), and standardized morbidity-leakage ratio (SMLR [ratio of observed patients to expected patients calculated using the risk calculator established in the NCD]) were evaluated. The numbers of LDG and LLAR cases continued to decline in the first year of the pandemic in 2020 and were as low in 2021 as in 2020. Although the numbers of robot-assisted LDG and LLAR cases increased, the growth rate was lower than the rate of increase prior to the pandemic. Mortality and anastomotic leakage, two of the most important complications, as assessed by SMR and SMLR, did not worsen during the pandemic in comparison to the pre-pandemic period. Laparoscopic surgeries were performed safely in Japan and were not affected by the COVID-19 pandemic.

The efficacy and safety of enhanced recovery after surgery (ERAS) Program in laparoscopic distal gastrectomy: a systematic review and meta-analysis of randomized controlled trials

Background Although ERAS Program had some advantages in laparoscopic distal gastrectomy (LDG), its efficacy and safety remained unclear. We conducted a systematic review and meta-analysis to assess the efficacy and safety of the ERAS group and the traditional care (TC) group in LDG. Methods Multiple databases were retrieved from 1 January 2000 to 30 April 2023. The risk ratio (RR), standardized mean difference (SMD) and their 95% confidence interval (CI) were used to estimate the results. Results Our meta-analysis contained 17 randomized controlled trials (RCTs) studies, which comprised 1468 patients. Regarding efficacy, the ERAS group had significantly shorter postoperative time to first flatus (SMD = −1.29 [95% CI: −1.68, −0.90]), shorter time to first defecation (SMD = −1.26 [95% CI: −1.90, −0.61]), shorter hospital stays (SMD = −0.99 [95% CI: −1.34, −0.63]), and lower hospitalization costs (SMD = −1.17 [95% CI: −1.86, −0.48]) compared to the TC group. Furthermore, in the ERAS group, C-reactive protein levels were lower on postoperative days 1, 3 or 4, and 7; albumin levels were higher on postoperative days 3 or 4 and 7; and interleukin-6 levels were lower on postoperative days 1 and 3. Regarding safety, the overall postoperative complication rate was lower in the ERAS group (RR: 0.76 [95% CI: 0.60, 0.97]), but there was no significant difference in the individual postoperative complication rate. Other indicators were also not statistically significant. Conclusion The combination of ERAS Program with laparoscopy surgery was safe and effective for the perioperative management of patients with distal gastric cancer.

Laparoscopic versus open distal gastrectomy for advanced gastric cancer in elderly patients: a propensity-score matched analysis

BackgroundScarce research has reported the efficacy and safety of laparoscopic distal gastrectomy in elderly patients. This retrospective study aimed to compare the outcomes of laparoscopic and open distal gastrectomy for advanced gastric cancer in elderly patients.MethodsA total of 303 elderly patients who underwent distal gastrectomy for advanced gastric cancer from June 2017 to June 2021 were enrolled. Variables used to calculate propensity score matching included sex, age, body mass index, American Society of Anesthesiologists, history of diabetes, and history of hypertension. The statistical significance of continuous variables was tested using an independent sample t test. chi-square or Fisher’s exact tests were used for categorical variables. Kaplan–Meier curve and log-rank test were used for the evaluation of 3-year overall survival and recurrence-free survival.ResultsAfter performing 1:1 propensity score matching, 248 patients were included for analysis (laparoscopic = 124, open = 124). Compared with the open group, the laparoscopic group showed significant advantages in estimated blood loss (P < 0.001), pain scale on the first postoperative day (P = 0.002), time to first flatus (P = 0.004), time to first liquid diet (P = 0.005), hospital stays (P < 0.001), and total complications (P = 0.011), but devoted much more operation time (P < 0.001). No statistical difference was observed between the two groups in 3-year recurrence-free survival (P = 0.315) or overall survival (P = 0.159).ConclusionsOur analysis demonstrated that laparoscopic surgery had the advantages of less intraoperative blood loss, fewer postoperative complications, and faster postoperative recovery in distal gastrectomy for advanced gastric, indicating that laparoscopic distal gastrectomy is safe and effective for treating elderly patients with distal gastric cancer.

Short-term outcomes of laparoscopic and robotic distal gastrectomy for gastric cancer: Real-world evidence from a large-scale inpatient database in Japan.

Robotic distal gastrectomy (RDG) has been widely performed throughout Japan since it became insured in 2018. This study aimed to evaluate the short-term outcomes of RDG and laparoscopic distal gastrectomy (LDG) for gastric cancer using real-world data. A total of 4161 patients who underwent LDG (n = 3173) or RDG (n = 988) for gastric cancer between April 2018 and October 2022 were identified through the Japanese Diagnosis Procedure Combination Database, which covers 42 national university hospitals. The primary outcome was postoperative in-hospital mortality rate. The secondary outcomes were postoperative complication rates, time to diet resumption, and postoperative length of stay (LOS). In-hospital mortality and postoperative complication rates in the RDG group were comparable with those in the LDG group (0.1% vs. 0.0%, p = 1.000, and 8.7% vs. 8.2%, p = 0.693, respectively). RDG was associated with a longer duration of anesthesia (325 vs. 262 min, p < 0.001), similar time to diet resumption (3 vs. 3 days, p < 0.001), and shorter postoperative LOS (10 vs. 11 days, p < 0.001) compared with LDG. RDG was performed safely and provided shorter postoperative LOS, since it became covered by insurance in Japan.

The benefits of R anastomotic technique for Billroth-II reconstruction with Braun anastomosis during totally laparoscopic distal gastrectomy: a propensity score matching analysis.

Currently, there is no consensus on the most appropriate anastomotic site, anastomotic line, and direction for Billroth-II reconstruction with Braun anastomosis (B-II-B anastomosis) during totally laparoscopic distal gastrectomy (TLDG). Herein, the authors presented a novel anastomotic technique called R anastomosis for B-II-B anastomosis and compared it with the conventional B-II-B anastomosis technique to assess its feasibility, safety, and effectiveness. Between March 2019 and September 2022 in our centre, R anastomosis was performed on 123 patients undergoing TLDG for distal gastric cancer. A retrospective review of a prospectively collected database identified patients who underwent TLDG between January 2010 and September 2022. Patients who underwent R anastomosis were matched in a 1:1 ratio with patients who underwent conventional anastomosis using a propensity score based on age, sex, preoperative BMI, American Society of Anesthesiologists (ASA) score, and the history of abdominal surgery. Surgical and postoperative outcomes and clinicopathological data were analyzed for both groups. During the study period, 246 patients were included, 123 in each group. No intraoperative complications associated with digestive tract reconstruction and no cases of conversion to open surgery were reported in either group; furthermore, no incidences of perioperative mortality were noted in either group. The R group had a significantly reduced anastomotic time compared to the control group (30 ± 4.1 vs. 36 ± 5.3 min, P < 0.001). Perioperatively, the incidences of Clavien-Dindo grade II or higher complications were 6.5% (8/123) and 12.2% (15/123) in the R and control groups with no significant difference between the two groups. Postoperative gastric emptying dysfunction was found in five and one patient in the control and R groups, respectively. R anastomosis is a safe and effective technique for B-II-B anastomosis following TLDG. This novel technique enhances the convenience of performing anastomosis and can reduce postoperative gastric emptying dysfunction.

Surgical Outcomes of Laparoscopic-assisted Distal Gastrectomy Versus Totally Laparoscopic Distal Gastrectomy Billroth I for Gastric Cancer.

The present study aimed to compare intraoperative and postoperative outcomes of laparoscopic-assisted distal gastrectomy versus totally laparoscopic distal gastrectomy (TLDG) Billroth I (BI) for gastric cancer and to assess the impact of the initial introduction phase of TLDG BI anastomosis. The study analyzed the prospectively collected data of patients who underwent laparoscopic distal gastrectomy BI from 2014 to 2021 at Seoul National University Hospital. Among 1116 patients, laparoscopic-assisted distal gastrectomy BI was performed in 566 patients and TLDG BI was performed in 550 patients. The total laparoscopic arm had a faster mean operative time (190 vs 208 min; P < 0.001) and a shorter postoperative hospital stay (7.4 vs 7.9 d; P < 0.001). Local complications were higher in the total laparoscopic group (17.6% vs 9.9%; P = 0.008) during the early introduction phase. The total laparoscopic approach for BI reconstruction is safe and effective with faster operative time, shorter hospital stays, and less wound infection, but it may be associated with an increase in postoperative surgical complications and hospital stay in the early introduction phase.

A gastroduodenal artery that branched from the celiac artery in gastrectomy: A rare case of an anatomical variant

AbstractUnderstanding anatomical anomalies of the branch of the celiac artery for safe gastrectomy is important. We report a case of laparoscopic distal gastrectomy with D1+ lymph node dissection for early gastric cancer with a vascular anatomical anomaly of the celiac artery. A 45‐year‐old woman was referred to our hospital because of early gastric cancer. Computed tomography showed an anatomical variation of the gastroduodenal artery, which branched from the celiac artery. The celiac artery also branched into the left gastric artery, the splenic artery, and the common hepatic artery. Preoperative understanding of an unusual branch of the celiac artery enabled a safe laparoscopic surgery. There were no postoperative complications. The Adachi classification or Michel classification is used for an anatomical anomaly of the celiac artery, but to the best of our knowledge, this case has not been previously classified and is the first reported case.

Laparoscopic gastrectomy for gastric cancer: A single cancer center experience.

Laparoscopic gastrectomy (LG) was challenging to most surgeons due to the two-dimensional view, difficult manipulations of the instruments, ergonomic discomfort, and the associated muscular spasm and effort. Technological advances with improved surgical experience, have made LG a more feasible and favorable approach for gastric cancer (GC) patients. LG was performed in 44 patients with GC between July 2015 to June 2022, in the Department of Surgical Oncology, Oncology Center, Mansoura University, Egypt, and we assessed the surgical outcomes of this approach as an initial experience of a single cancer center. Twenty-seven patients underwent laparoscopic distal gastrectomy, and seventeen underwent laparoscopic total gastrectomy. Two cases had combined resection. Operative time was 339.2 ± 76.73 min, while blood loss was 153.86 ± 57.51 mL. The patients were ambulant on postoperative day 0, oral intake was started within three days (range 1-5 days) and the hospital stay was six days (range 3-9 days). LG for GC is a feasible approach for both early and advanced GC patients as it allows for adequate diagnosis of the peritoneal disease, meticulous dissection, and identification of the lymph nodes with minimal blood loss and decrease surgery-related problems and encourage the early patients' discharge from hospital and return to daily life activities.

Short- and long-term outcomes of Roux-en-Y and Billroth II with Braun reconstruction in total laparoscopic distal gastrectomy: a retrospective analysis

BackgroundThe controversy surrounding Roux-en-Y (R-Y) and Billroth II with Braun (BII + B) reconstruction as an anti-bile reflux procedure after distal gastrectomy has persisted. Recent studies have demonstrated their efficacy, but the long-term outcomes and postoperative quality of life (QoL) among patients have yet to be evaluated. Therefore, we compared the short-term and long-term outcomes of the two procedures as well as QoL.MethodsThe clinical data of 151 patients who underwent total laparoscopic distal gastrectomy (TLDG) at the Gastrointestinal Surgery Department of the Second Hospital of Fujian Medical University from January 2016 to December 2019 were retrospectively analyzed. Of these, 57 cases with Roux-en-Y procedure (R-Y group) and 94 cases with Billroth II with Braun procedure were included (BII + B group). Operative and postoperative conditions, early and late complications, endoscopic outcomes at year 1 and year 3 after surgery, nutritional indicators, and quality of life scores at year 3 postoperatively were compared between the two groups.ResultsThe R-Y group recorded a significantly longer operative time (194.65 ± 21.52 vs. 183.88 ± 18.02 min) and anastomotic time (36.96 ± 2.43 vs. 27.97 ± 3.74 min) compared to the BII + B group (p < 0.05). However, no other significant differences were observed in terms of perioperative variables, including blood loss (p > 0.05). Both groups showed comparable rates of early and late complications. Endoscopic findings indicated similar food residuals at years 1 and 3 post-surgery for both groups. The R-Y group had a lower occurrence of residual gastritis and bile reflux at year 1 and year 3 after surgery, with a statistically significant difference (p < 0.001). Reflux esophagitis was not significantly different between the R-Y and BII + B groups in year 1 after surgery (p = 0.820), but the R-Y group had a lower incidence than the BII + B group in year 3 after surgery (p = 0.023). Nutritional outcomes at 3 years after surgery did not differ significantly between the two groups (p > 0.05). Quality of life scores measured by the QLQ-C30 scale were not significantly different between the two groups. However, on the QLQ-STO22 scale, the reflux score was significantly lower in the R-Y group than in the BII + B group (0 [0, 0] vs. 5.56 [0, 11.11]) (p = 0.003). The rest of the scores were not significantly different (p > 0.05).ConclusionBoth R-Y and B II + B reconstructions are equally safe and efficient for TLDG. Nevertheless, the R-Y reconstruction reduces the incidence of residual gastritis, bile reflux, and reflux esophagitis, as well as postoperative reflux symptoms, and provides a better quality of life for patients. R-Y reconstruction is superior to BII + B reconstruction for TLDG.
