Abstract
INTRODUCTION Laparoscopic proximal gastrectomy with double flap technique (LPG-DFT) reconstruction has been used for proximal early gastric cancer in recent years. However, its feasibility and safety remain uncertain, as only a few retrospective studies have contained postoperative complications and long-term survival data. LPG-DFT for proximal early gastric cancer is still in the early stages of research. Large-scale, prospective randomised controlled trials (RCTs) are necessary to assess the value of LPG-DFT for proximal early gastric cancer. METHODS AND ANALYSIS This study is a multicentre, prospective, open-label, RCT that investigates the antireflux effect of LPG-DFT compared with laparoscopic total gastrectomy with Roux-en-Y (LTG-RY) reconstruction for proximal early gastric cancer. A total of 216 eligible patients will be randomly assigned to the LPG-DFT group or the LTG-RY group at a 1:1 ratio using a central, dynamic and stratified block randomisation method, if inclusion criteria are met. General and clinical data will be collected when the patient is enrolled in the study and keep pace with the patient at each stage of his medical and follow-up pathway. The primary endpoint is the proportion of patients with reflux esophagitis (Los Angeles Grade B or more) within 12 months postoperatively. The secondary endpoints included intraoperative outcomes, postoperative recovery, postoperative pain assessment, pathological outcomes, postoperative quality of life, postoperative nutrition status, morbidity and mortality rate, and oncological outcomes (3-year overall survival (OS), 3-year disease-free survival (DFS), 5-year DFS and 5-year OS). ETHICS AND DISSEMINATION The protocol is approved by the Sun Yat-Sen Memorial Hospital of Sun Yat-Sen University ethics committee (registration number: SYSKY-2022-276-02) on 28 September 2022.We will report the positive as well as negative findings in international peer-reviewed journals. TRIAL REGISTRATION NUMBER NCT05890339.

Risk factors and clinical significance of lower perigastric lymph node metastases in Siewert type II and III esophagogastric junction adenocarcinoma: a retrospective cohort study. Surg Endosc 2024; 38:3828-3837. [PMID: 38822144 PMCID: PMC11219428 DOI: 10.1007/s00464-024-10875-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2024] [Accepted: 04/20/2024] [Indexed: 06/02/2024]
Abstract
BACKGROUND No consensus has been concluded with regarding to the scope of lymph node (LN) dissection for Siewert type II and III adenocarcinoma of the esophagogastric junction (AEG). This study aimed to explore risk factors for lower perigastric LN (LPLN) metastases (including no. 4d, 5, 6, and 12a LN stations) and analyze the indications for LPLN dissection. METHODS In total, 302 consecutive patients with Siewert type II and III AEG who underwent total gastrectomy (TG) were enrolled. The logistic regression model was used to perform uni- and multivariate analyses of risk factors for LPLN metastases. Kaplan-Meier curves were used for survival analysis, and log-rank tests were used for group comparisons. Basing on the guidelines of Japanese Gastric Cancer Association, the LN metastases (LNM) as well as the efficiency index (EI) of each LN station was further evaluated. RESULTS The independent risk factors for LPLN metastases in patients with Siewert type II and III AEG were distance from the esophagogastric junction (EGJ) to the distal end of the tumor (> 4.0 cm), preoperative carcinoembryonic antigen (CEA) ( +), pT4 stage, and HER-2 ( +). LPLN metastases was an independent risk factor for overall survival following TG. The LNM and EI of LPLN were 8.6% and 2.31%, respectively. The LNM of LPLN > 10% under the stratification of the distance from the EGJ to the distal end of the tumor (> 4.0 cm), pT4, preoperative CEA ( +), and HER-2 ( +) exhibited EI values of 3.55%, 2.09%, 2.51%, and 3.64%, respectively. CONCLUSIONS LPLN metastases was a malignant factor for the prognosis of patients with Siewert type II and III AEG. For patients with preoperative CEA ( +), pT4 stage, HER-2 ( +), and the distance from the EGJ to the distal end of the tumor (> 4.0 cm), TG with LPLN dissection is prioritized for clinical recommendation.

Abstract
BACKGROUND Proximal gastrectomy (PG) is one of function-preserving gastrectomy (FPG). In this study, we compared the long-term results of proximal gastric cancer (PGC) patients undergoing proximal gastrectomy and total gastrectomy (TG). METHOD Patients diagnosed with PGC and receiving PG or TG between 2004 and 2020 were selected from the Surveillance, Epidemiology, and End Results (SEER) database. Propensity score matching (PSM) was applied to minimize confounding factors. Kaplan-Meier analysis and log-rank test were used to compare overall survival (OS) and cancer-specific survival (CSS) between the PG and TG groups. Univariate and multivariate Cox regression analyses were performed to identify independent risk factors affecting OS. RESULT A total of 3916 patients were recruited according to the inclusion and exclusion criteria, with 2614 undergoing PG and 1302 undergoing TG. After 1:1 PSM matching, 912 pairs of data were included for analysis. Before PSM matching, PG group tended to have better OS and CSS outcomes. However, after PSM matching, both surgical approaches showed similar long-term results. CONCLUSION PG for PGC yields comparable long-term outcomes to TG and demonstrates safety in terms of oncologic outcomes.

Ann Surg Treat Res 2024; 106:313-321. [PMID: 38868586 PMCID: PMC11164659 DOI: 10.4174/astr.2024.106.6.313] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2024] [Revised: 03/28/2024] [Accepted: 04/02/2024] [Indexed: 06/14/2024] Open
Abstract
Purpose Laparoscopic proximal gastrectomy with double-tract reconstruction (LPG-DTR) expectedly results in improved nutritional status and less body weight loss than conventional total gastrectomy in upper-third gastric cancer. This study aimed to investigate the food passage patterns following LPG-DTR and its effect on nutritional outcomes up to 1 year after surgery. Methods This prospective cohort study recruited 10 patients with early gastric cancer scheduled for LPG-DTR. Nutritional indices and body composition were assessed every 3 months up to 12 months. Liquid and solid food transits were evaluated with fluoroscopic upper gastrointestinal study and radionuclide scintigraphy, respectively. Results At 12 months, patients exhibited a body weight loss of 14.5% ± 3.6%. The main passage routes for liquid and solid foods differed, primarily via the interposed jejunum for liquids, whereas via both tracts for solids. The median half-life of solid food emptying from the remnant distal stomach was 105.1 minutes (range, 50.8-2,194.2 minutes), and duodenal passage of solid food was noted in 9 of 10 patients. Those with gastric half-emptying time >3 hours demonstrated greater weight loss (19.5% ± 1.4% vs. 12.5% ± 1.1%, P = 0.024) and more pronounced reduction in serum albumin levels (-0.5 ± 0.3 g/dL vs. 0.0 ± 0.2 g/dL, P = 0.024) after 12 months. Conclusion LPG-DTR demonstrated varying food passage patterns depending on the food contents and delayed solid food emptying from the remnant stomach was associated with more substantial weight loss.

Abstract
BACKGROUND This study aimed to investigate the oncologic long-term safety of proximal gastrectomy for upper-third advanced gastric cancer (AGC) and Siewert type II esophagogastric junction (EGJ) cancer. METHODS The study enrolled patients who underwent proximal gastrectomy (PG) or total gastrectomy (TG) with standard lymph node (LN) dissection for pathologically proven upper-third AGC and EGJ cancers between January 2007 and December 2018. Propensity score-matching with a 1:1 ratio was performed to reduce the influence of confounding variables such as age, sex, tumor size, T stage, N stage, and tumor-node-metastasis (TNM) stage. Kaplan-Meier survival analysis was performed to analyze oncologic outcome. The prognostic factors of recurrence-free survival (RFS) were analyzed using the Cox proportional hazard analysis. RESULTS Of the 713 enrolled patients in this study, 60 received PG and 653 received TG. Propensity score-matching yielded 60 patients for each group. The overall survival rates were 61.7 % in the PG group and 68.3 % in the TG group (p = 0.676). The RFS was 86.7 % in the PG group and 83.3 % in the TG group (p = 0.634). The PG group showed eight recurrences (1 anastomosis site, 1 paraaortic LN, 1 liver, 1 spleen, 1 lung, 1 splenic hilar LN, and 2 remnant stomachs). In the multivariate analysis, the operation method was not identified as a prognostic factor of tumor recurrence. CONCLUSION The patients who underwent PG had a long-term oncologic outcome similar to that for the patients who underwent TG for upper-third AGC and EGJ cancer.

Safety and short-term outcomes of a modified valvuloplastic esophagogastrostomy versus gastric tube anastomosis after laparoscopy-assisted proximal gastrectomy: a retrospective cohort study. Surg Endosc 2024; 38:1523-1532. [PMID: 38272976 PMCID: PMC10881610 DOI: 10.1007/s00464-023-10663-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2023] [Accepted: 12/22/2023] [Indexed: 01/27/2024]
Abstract
BACKGROUND There is no optimal reconstruction method after proximal gastrectomy. The valvuloplastic esophagogastrostomy can reduce postoperative reflux esophagitis, but it is technically complex with a long operation time. The gastric tube anastomosis is technically simple, but the incidences of reflux esophagitis and anastomotic stricture are higher. METHODS We have devised a modified valvuloplastic esophagogastrostomy after laparoscopy-assisted proximal gastrectomy (LAPG), the arch-bridge anastomosis. After reviewing our prospectively maintained gastric cancer database, 43 patients who underwent LAPG from November 2021 to April 2023 were included in this cohort study, with 25 patients received the arch-bridge anastomosis and 18 patients received gastric tube anastomosis. The short-term outcomes were compared between the two groups to evaluate the efficacy of the arch-bridge anastomosis. Reporting was consistent with the STROCSS 2021 guideline. RESULTS The median operation time was 180 min in the arch-bridge group, significantly shorter than the gastric tube group (p = 0.003). In the arch-bridge group, none of the 25 patients experienced anastomotic leakage, while one patient (4%) experienced anastomotic stricture requiring endoscopic balloon dilation. The postoperative length of stay was shorter in the arch-bridge group (9 vs. 11, p = 0.034). None of the patients in the arch-bridge group experienced gastroesophageal reflux and used proton pump inhibitor (PPI), while four (22.2%) patients in the gastric tube group used PPI (p = 0.025). The incidence of reflux esophagitis (Los Angeles grade B or more severe) by endoscopy was lower in the arch-bridge group (0% vs. 25.0%). CONCLUSION The arch-bridge anastomosis is a safe, time-saving, and feasible reconstruction method. It can reduce postoperative reflux and anastomotic stricture incidences in a selected cohort of patients undergoing laparoscopy-assisted proximal gastrectomy.

Abstract
Background The oncological relevance of proximal gastrectomy in advanced gastric cancer remains unclear. We aimed to examine the frequency of lymph node metastasis in advanced gastric cancer to determine the oncological validity of proximal gastrectomy selection. Materials and methods This study included consecutive 71 patients with locally advanced gastric cancer in the upper third of the stomach who underwent total gastrectomy at our institution between 2001 and 2017. Lymph node metastasis and its therapeutic value index were examined to identify candidates for proximal gastrectomy. Metastatic and 3-year overall survival rates of numbers 3a and 3b lymph nodes were examined from 2010 to 2019. Results The metastatic rate and therapeutic value index of numbers 4d, 5, 6, and 12a lymph nodes were zero or low. The number 3 lymph node had a metastatic rate and therapeutic value index of 36.6 % and 31.1, respectively. The metastatic and 3-year overall survival rates of the number 3a lymph node were 32.7 % and 89 %, respectively, whereas those of the number 3b lymph node were 3.8 % and 100 %, respectively. All patients with positive metastasis to the number 3b lymph node received adjuvant chemotherapy. Histopathological findings of positive metastasis to the number 3b lymph node were located in the lesser curvature, and the tumor diameter exceeded 40 mm. Conclusion For advanced gastric cancer of the upper third of the stomach, the indications of localization to the lesser curvature and a tumor diameter of >40 mm should be considered cautiously.

Abstract
PURPOSE This study assesses the metastasis rate of the key distal lymph nodes (KDLN) that are not routinely dissected in proximal gastrectomy, aiming to explore the oncological safety of proximal gastrectomy for upper gastric cancer who underwent neoadjuvant chemotherapy. METHODS We analyzed a cohort of 150 patients with proximal locally advanced gastric cancer (cT3/4 before chemotherapy) from two high-volume cancer centers in China who received preoperative neoadjuvant chemotherapy (NAC) and total gastrectomy with lymph node dissection. Metastasis rate of the KDLN (No.5/6/12a) and the risk factors were analyzed. RESULTS Key distal lymph node metastasis was detected in 10% (15/150) of patients, with a metastasis rate of 6% (9/150) in No. 5 lymph nodes, 6.7% (10/150) in No. 6 lymph nodes, and 2.7% (2/75) in No. 12a lymph nodes. The therapeutic value index of KDLN as one entity is 5.8. Tumor length showed no correlation with KDLN metastasis, while tumor regression grade (TRG) emerged as an independent risk factor (OR: 1.47; p-value: 0.04). Of those with TRG3 (no response to NAC), 80% (12/15) was found with KDLN metastasis. CONCLUSION For cT3/4 proximal locally advanced gastric cancer patients, the risk of KDLN metastasis remains notably high even after NAC. Therefore, proximal gastrectomy is not recommended; instead, total gastrectomy with thorough distal lymphadenectomy is the preferred surgical approach.

Total versus proximal gastrectomy for proximal gastric cancer after neoadjuvant chemotherapy: a multicenter retrospective propensity score-matched cohort study. Int J Surg 2024; 110:1000-1007. [PMID: 38085808 PMCID: PMC10871602 DOI: 10.1097/js9.0000000000000927] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2023] [Accepted: 11/09/2023] [Indexed: 02/17/2024]
Abstract
BACKGROUND This study aimed to analyze and compare the short-term and long-term outcomes of proximal gastrectomy (PG) and total gastrectomy (TG) in patients with locally advanced proximal gastric cancer (GC) following neoadjuvant chemotherapy (NACT). METHOD A multicenter retrospective cohort study and propensity score matching (PSM) were employed. The authors examined 367 patients with proximal GC who received NACT followed by PG ( n =164) or TG ( n =203) at two Chinese medical institutions between December 2009 and December 2022. Clinical and pathological parameters, postoperative complications, and 5-year overall survival (OS) and recurrence-free survival (RFS) were compared between the two groups. The dissection status and metastasis rate of each lymph node station were assessed. RESULTS After PSM, 80 patients were enrolled in both TG and PG group, and baseline characteristics were comparable between the groups (all P >0.05). The TG group had a higher total number of lymph nodes retrieved ( P <0.001) and longer operative time ( P =0.007) compared to the PG group. The incidence of Clavien-Dindo grade II or higher postoperative complications was similar between the TG group (21.3%, 17/80) and the PG group (17.5%, 14/80) ( P =0.689). The 5-year OS rates were 68.4 for the PG group and 66.0% for the TG group ( P =0.881), while the 5-year RFS rates were 64.8 and 61.9%, respectively ( P =0.571), with no statistically significant differences. Metastasis rates at lymph node stations #4d, #5, #6, and #12a were notably low in the TG group, with values of 2.74, 0.67, 1.33, and 1.74%, respectively. CONCLUSION For proximal GC patients following NACT, PG maintains comparable curative potential and oncological efficacy to TG, making it a safe option.

Abstract
OBJECTIVE To investigate the clinical efficacy of proximal gastrectomy with narrow gastric tube anastomosis (PG-NGT) and total gastrectomy with Roux-en-Y anastomosis (TG-RY) for upper gastric cancer. MATERIALS AND METHODS One hundred sixty-three upper gastric cancer patients were enrolled into the PG-NGT group and TG-RY group. The propensity score matching method was used to conduct a one-to-one match between the two groups with 38 patients in each group. RESULTS Compared with the TG-RY group, the PG-NGT group had significantly (P < 0.05) shorter operation time, shorter hospital stay, and less intraoperative blood loss. The TG-RY group had significantly (P = 0.009) more lymph nodes dissected and greater (P = 0.014) total cost than the PG-NGT group, but no significant difference existed in the surgical cost between the two groups (P = 0.214). There was no significant (P > 0.05) difference in the incidence of anastomotic stenosis (10.5% vs. 13.1%) or the reflux esophagitis rate (8.6% vs. 9.1%) in the PG-NGT group and the TG-RY group. One year after surgery, the weight and hemoglobin and albumin levels in the PG-NGT group were significantly (P < 0.05) higher than those in the TG-RY group. CONCLUSIONS PG-NGT may be better than TG-RY in improving patient weight loss and hemoglobin and albumin levels, without increasing the rate of anastomotic stenosis and reflux symptoms.

Impact of D2 Gastrectomy for Locally Advanced Gastric Cancer in the Era of Effective Adjuvant Chemotherapy. World J Surg 2023; 47:1512-1518. [PMID: 36820868 DOI: 10.1007/s00268-023-06934-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 12/25/2022] [Indexed: 02/24/2023]
Abstract
BACKGROUND Gastrectomy with D2 dissection has been established as the standard procedure for locally advanced gastric cancer in the era of surgery alone. However, no consideration has been given to the efficacy of dissection in the era of effective adjuvant chemotherapy. METHODS This study included 1298 advanced gastric cancer patients, consisting of 725 cases treated between January 2000 and December 2006 (Former group), and 573 cases treated between January 2007 and July 2015 (Latter group). Clinicopathological data were collected, survival and the therapeutic value index were determined. RESULTS The background characteristics were well balanced, except for age, tumor location, and intraoperative blood loss. The Latter group showed the following characteristics: an older population (p < 0.001), a frequent upper location (p = 0.008), and less blood loss (p < 0.001). Adjuvant chemotherapy was administered to 75.2% of the Latter group and was 9.4% in the Former group. The 5-year overall survival rate of the Latter group was 75.7% (95% confidence interval: 71.7-79.1), significantly better than that of the Former group (70.0%, 95% confidence interval: 66.5-73.2) (p = 0.025). Improvement in the index from the Former group was observed in the Latter group at almost all stations. The ratio of the index between these two groups was 1.09 at the D1 station and 1.19 at the D2 station. CONCLUSION The therapeutic value index was improved in all nodal stations by S-1 adjuvant chemotherapy, regardless of whether the D1 or D2 nodes were involved. D2 gastrectomy would be still important for locally advanced gastric cancer in the era of effective adjuvant chemotherapy.

Abstract
OPINION STATEMENT The surgical treatment of gastric carcinoma has progressed significantly in the past few decades. A major milestone was the establishment of multimodal therapies for locally advanced tumours. Improvements in the technique of endoscopic resection have supplanted surgery in the early stages of many cases of gastric cancer. In cases in which an endoscopic resection is not possible, surgical limited resection procedures for the early stages of carcinoma are an equal alternative to gastrectomy in the field of oncology. Proximal gastrectomy is extensively discussed in this context. Whether proximal gastrectomy leads to a better quality of life and better nutritional well-being than total gastrectomy depends on the reconstruction chosen. The outcome cannot be conclusively assessed at present. For locally advanced stages, total or subtotal gastrectomy with D2 lymphadenectomy is now the global standard. A subtotal gastrectomy requires sufficiently long tumour-free proximal resection margins. Recent data indicate that proximal margins of at least 3 cm for tumours with an expansive growth pattern and at least 5 cm for those with an infiltrative growth pattern are sufficient. The most frequently performed reconstruction worldwide following gastrectomy is the Roux-en-Y reconstruction. However, there is evidence that pouch reconstruction is superior in terms of quality of life and nutritional well-being. Oncological gastric surgery is increasingly being performed laparoscopically. The safety and oncological equivalency were first demonstrated for early carcinomas and then for locally advanced tumours, by cohort studies and RCTs. Some studies suggest that laparoscopic procedures may be advantageous in early postoperative recovery. Robotic gastrectomy is also increasing in use. Preliminary results suggest that robotic gastrectomy may have added value in lymphadenectomy and in the early postoperative course. However, further studies are needed to substantiate these results. There is an ongoing debate about the best treatment option for gastric cancer with oligometastatic disease. Preliminary results indicate that certain patient groups could benefit from resection of the primary tumour and metastases following chemotherapy. However, the exact conditions in which patients may benefit have yet to be confirmed by ongoing trials.

Abstract
IMPORTANCE Patients undergoing proximal gastrectomy (PG) with double-tract reconstruction (DTR) have been reported to have an incidence of reflux esophagitis that is as low as that observed after total gastrectomy (TG). It is unclear whether PG has an advantage over TG for the treatment of patients with upper early gastric cancer (GC). OBJECTIVE To evaluate the effect of laparoscopic PG with DTR (LPG-DTR) vs laparoscopic TG (LTG) on levels of hemoglobin and vitamin B12 supplementation required among patients with clinically early GC in the upper third of the stomach (upper-third early GC). DESIGN, SETTING, AND PARTICIPANTS This multicenter open-label superiority randomized clinical trial was conducted at 10 institutions in Korea. A total of 138 patients with upper-third cT1N0M0 GC were enrolled between October 27, 2016, and September 9, 2018. Follow-up ended on December 3, 2020. INTERVENTIONS Patients were randomized to undergo either LPG-DTR or LTG. MAIN OUTCOMES AND MEASURES The primary co-end points were change in hemoglobin level and cumulative amount of vitamin B12 supplementation at 2 years after LPG-DTR or LTG. The secondary end points included morbidity, postoperative reflux esophagitis, quality of life, overall survival, and disease-free survival. Quality of life outcomes were assessed using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ) 30-item core questionnaire (C30) and the EORTC QLQ stomach cancer-specific questionnaire at 3 months, 12 months, and 24 months. RESULTS Among 138 patients (mean [SD] age, 60.0 [10.9] years; 87 men [63.0%]; all of Asian race and Korean ethnicity), 68 (mean [SD] age, 56.7 [10.4] years; 39 men [57.4%]) were randomized to receive LPG-DTR and 69 (mean [SD] age, 61.3 [11.3] years; 48 men [69.6%]) were randomized to receive LTG. The mean (SD) changes in hemoglobin levels from baseline to month 24 were -5.6% (7.4%) in the LPG-DTR group and -6.9% (8.3%) in the LTG group, for an estimated difference of -1.3% (95% CI, -4.0% to 1.4%; P = .35). The mean (SD) cumulative amount of vitamin B12 supplementation was 0.4 (1.3) mg in the LPG-DTR group and 2.5 (3.0) mg in the LTG group, for an estimated difference of 2.1 mg (95% CI, 1.3-2.9 mg; P < .001). The late complication rates in the LPG-DTR and LTG groups were 17.6% and 10.1%, respectively (P = .31). The incidence of reflux esophagitis was not different between the LPG-DTR and LTG groups (2.9% vs 2.9%; P = .99). Compared with the LTG group, the LPG-DTR group had better physical functioning scores (85.2 [15.6] vs 79.9 [19.3]; P = .03) and social functioning scores (89.5 [17.9] vs 82.4 [19.4]; P = .03) on the EORTC QLQ-C30. Two-year overall survival (98.5% vs 100%; P = .33) and disease-free survival (98.5% vs 97.1%; P = .54) did not significantly differ between the LPG-DTR vs LTG groups. CONCLUSIONS AND RELEVANCE In this study, patients with upper-third early GC who received LPG-DTR required less vitamin B12 supplementation than those who received LTG, with no increase in complication rates and no difference in overall and disease-free survival rates. There was no difference in change in hemoglobin level between groups. In addition, the LPG-DTR group had better physical and social functioning than the LTG group. These findings suggest that LPG-DTR may be as safe as LTG and may be a function-preserving procedure for the treatment of patients with upper-third early GC.

Abstract
LN dissection is essential for accurately staging and improving GC patient prognosis. However, the compliance rate for No. 12a LND in practice is low, and its necessity is controversial. Data from GC patients who underwent total gastrectomy (TG)/distal gastrectomy (DG) plus D2 lymphadenectomy between January 2000 and December 2017 at West China Hospital, Sichuan University were reviewed. No. 12a LND noncompliance's effect on the long-term prognosis of patients with GC after D2 gastrectomy was explored. Of the 2788 patients included, No. 12a LND noncompliance occurred in 1753 patients (62.9%). Among 1035 patients with assessable LNs from station 12a, 98 (9.5%) had positive LNs detected at station 12a. No. 12a LN metastasis patients (stage IV not included) had significantly better overall survival (OS) than TNM stage IV patients (p = 0.006). Patients with No. 12a LND compliance had a significantly higher OS than those without, both before (p < 0.001) and after (p < 0.001) PSM. Cox multivariate analysis confirmed that No. 12a LND noncompliance was an independent prognostic factor before (HR 1.323, 95% CI 1.171-1.496, p < 0.001) and after (HR 1.353, 95% CI 1.173-1.560, p < 0.001) PSM. In conclusion, noncompliance with No. 12a LND compromised the long-term survival of patients who underwent D2 gastrectomy for GC.

Abstract
Background Proximal gastrectomy with gastric tubular reconstruction is a surgical procedure that can preserve function in patients with proximal gastric cancer. However, whether gastric tubular reconstruction with proximal gastrectomy has certain advantage in some aspects over total gastrectomy is controversial. To evaluate the benefit of gastric tubular reconstruction after proximal gastrectomy, we compared gastric tubular reconstruction with total gastrectomy for proximal gastric cancer. Method A total of 351 patients were enrolled. Concurrent total gastrectomy patients matched with the Proximal gastrectomy group in age, sex, body mass index, clinical stage, and ASA score were selected by propensity score matching. Preoperative basic information, perioperative indicators, histopathological features, postoperative complications and nutritional status, reflux were compared between the two groups. Results There was no significant difference in the incidence of reflux between two groups (14.8% and 6.5% respectively, P = 0.085). There were significant differences between the two groups in bowel function recovery (2.29 ± 1.16 vs. 3.01 ± 1.22; P = 0.039) and start of soft diet (4.06 ± 1.81 vs. 4.76 ± 1.69; P = 0.047). There were no significant differences between the two groups in nutritional status one year after surgery. However, the decrease in serum hemoglobin in the TG group at 3 and 6 months after surgery was significantly higher than that in the PG group (P = 0.032 and 0.046, respectively). One month after surgery, %BW loss in TG group was significantly lower than that in the PG group (P = 0.024). Conclusion The Proximal gastrectomy group has better clinical outcome and gastric tubular reconstruction is simple, similar complications and reflux rates, gastric tubular reconstruction may be more suitable for proximal gastric cancer.

Abstract
Gastric cancer is one of the most common cancers in Korea and the world. Since 2004, this is the 4th gastric cancer guideline published in Korea which is the revised version of previous evidence-based approach in 2018. Current guideline is a collaborative work of the interdisciplinary working group including experts in the field of gastric surgery, gastroenterology, endoscopy, medical oncology, abdominal radiology, pathology, nuclear medicine, radiation oncology and guideline development methodology. Total of 33 key questions were updated or proposed after a collaborative review by the working group and 40 statements were developed according to the systematic review using the MEDLINE, Embase, Cochrane Library and KoreaMed database. The level of evidence and the grading of recommendations were categorized according to the Grading of Recommendations, Assessment, Development and Evaluation proposition. Evidence level, benefit, harm, and clinical applicability was considered as the significant factors for recommendation. The working group reviewed recommendations and discussed for consensus. In the earlier part, general consideration discusses screening, diagnosis and staging of endoscopy, pathology, radiology, and nuclear medicine. Flowchart is depicted with statements which is supported by meta-analysis and references. Since clinical trial and systematic review was not suitable for postoperative oncologic and nutritional follow-up, working group agreed to conduct a nationwide survey investigating the clinical practice of all tertiary or general hospitals in Korea. The purpose of this survey was to provide baseline information on follow up. Herein we present a multidisciplinary-evidence based gastric cancer guideline.

Abstract
According to the World Health Organization, gastric cancer is the fifth most common type of tumor, and is the third most common cause of tumor-associated death. Although gastric cancer incidence rates have decreased in the past few decades, the prevalence of proximal gastric cancer has been steadily rising in developed countries. Techniques regarding the improvement of treatment options must thus be developed. This can be achieved through incorporating both a wider use of endoscopic surgery (endoscopic mucosal resection-EMR, endoscopic submucosal dissection-ESD) and a review of applied surgical interventions. Even though there is no single international consensus available, the Japanese Gastric Cancer Association (JGCA) recommends proximal gastrectomy with D1+ lymphadenectomy in early gastric tumors. Despite recommendations from Asian guidelines and the short term outcomes of the KLASS 05 trial, surgical treatments in Western countries still rely on total gastrectomy. This is mostly due to technical and oncological challenges regarding surgical interventions in a proximal gastrectomy. However, the residual stomach after a proximal gastrectomy has been shown to diminish the incidence of dumping syndrome and anemia, and even improve postoperative quality of life (QoL). Therefore, it is necessary to define the place of proximal gastrectomy in the treatment of gastric cancers.

Signature and Prediction of Perigastric Lymph Node Metastasis in Patients with Gastric Cancer and Total Gastrectomy: Is Total Gastrectomy Always Necessary? Cancers (Basel) 2022; 14:cancers14143409. [PMID: 35884470 PMCID: PMC9319199 DOI: 10.3390/cancers14143409] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2022] [Revised: 07/07/2022] [Accepted: 07/12/2022] [Indexed: 02/04/2023] Open
Abstract
Simple Summary The signature and prediction of perigastric lymph node metastasis (pLNM) is clinically important, but evidence is still lacking. Here, we aimed to identify an informative signature for the prediction of pLNMs in gastric cancer patients after total gastrectomy, and reassess the current indications for proximal gastrectomy and pylorus-preserving gastrectomy (PPG). We found that proximal gastrectomy may be expanded to patients with stage T1–T2 GC and/or tumor diameter < 4 cm in the upper-third stomach, while PPG may be expanded to include T1–T2/N0 and/or tumors < 4 cm in the middle-third stomach. Furthermore, we developed a new predictive factor, the shortest distance from the pylorus ring to the distal edge of the tumor, which showed good predictive performance for pLNMs. Abstract Background: A growing number of studies suggest that the current indications for partial gastrectomy, including proximal gastrectomy and pylorus-preserving gastrectomy (PPG), may be expanded, but evidence is still lacking. Methods: We retrospectively analyzed 300 patients with gastric cancer (GC) who underwent total gastrectomy. We analyzed the incidence of pLNMs in relation to tumor location, tumor size and T stage. We further identified predictive factors for perigastric lymph node metastasis (pLNM) in stations 1, 2, 3, 4sa, 4sb, 4d, 5, and 6. Results: No patients with upper-third T1–T2 stage GC had pLNMs in stations 4sa, 4sb, 4d, 5, or 6, but 3.8% of patients with stage T3 had 4d pLNM. No patients with upper-third GC < 4 cm in diameter had pLNMs in 2, 4sa, 4d, 5, or 6, and 2.3% of patients had pLNMs in 4sb. For middle-third GCs, 2.9% of patients with T1 stage had pLNMs in 4sa and 5, but no patients with T2 stage or tumors < 4 cm had pLNMs in 2, 4sa, or 5. The shortest distance from pylorus ring to distal edge of tumor (sDPD) was a new predictive factor for pLNMs in 2, 4d, 5, and 6. Conclusions: Proximal gastrectomy may be expanded to patients with stage T1–T2 GC and/or tumor diameter < 4 cm in the upper-third stomach, whereas PPG may be expanded to include T1–T2/N0 and/or tumors < 4 cm in the middle-third stomach. A new predictive factor, sDPD, showed good predictive performance for pLNMs, especially in stations 4d, 5, and 6.

Abstract
Purpose The incidence of adenocarcinoma of the esophagogastric junction (AEG) has increased in recent years, and the optimal surgical strategy for AEG remains highly controversial. We aimed to evaluate the safety and efficacy of proximal gastrectomy with double-tract reconstruction (PG-DT) for the treatment of patients with AEG. Materials and Methods We retrospectively analyzed patients with Siewert type II/III AEG between January 2013 and July 2018. Clinicopathological characteristics, survival, surgical outcomes, quality of life (QOL), and nutritional status were compared between the PG-DT and total gastrectomy with Roux-en-Y anastomosis (TG-RY) groups. Results After propensity score matching, 33 patients in each group were analyzed. There were no statistical differences between the 2 groups in terms of disease-free survival and overall survival. The surgical option was not an independent prognostic factor based on the multivariate analysis. In addition, no differences were found in terms of surgical complications. There were no significant differences in QOL assessed by the Visick grade, Gastrointestinal Symptom Rating Scale, or endoscopic findings. Furthermore, the long-term nutritional advantage of the PG-DT group was significantly greater than that of the TG-RY group. Conclusions PG-DT is a safe and effective procedure for patients with local Siewert type II/III AEG, regardless of the TNM stage.

Effect of Double-Channel Anastomosis and Esophagojejunal Anastomosis on Postoperative Recovery and Complications of Laparoscopic D2 Radical Gastrectomy for Gastric Cancer. JOURNAL OF HEALTHCARE ENGINEERING 2022; 2022:8281558. [PMID: 35368937 PMCID: PMC8967533 DOI: 10.1155/2022/8281558] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/27/2022] [Accepted: 02/18/2022] [Indexed: 11/17/2022]
Abstract
The aim of this study was to investigate the effects of double-channel anastomosis versus esophagojejunostomy on postoperative recovery and complications after laparoscopic D2 radical gastrectomy for early proximal gastric cancer. The cases were collected from 100 patients with early proximal gastric cancer admitted to our hospital from January 2017 to January 2021. According to different surgical methods, they were divided into control group (total gastrectomy + esophagojejunal anastomosis) and experimental group (D2 radical resection + double-channel anastomosis). The two groups were compared in terms of clinical outcomes (operative time, intraoperative blood loss, number of lymph nodes dissected, digestive tract anastomosis time, postoperative exhaust, and hospitalization days), postoperative complications, and nutritional status; the expression of T lymphocyte subsets in peripheral blood of the two groups was detected to reflect the recovery of immune ability. There was no significant difference between the observation group and the control group in clinical operation effect indexes (P < 0.05). The incidence of complications of dumping syndrome and reflux esophagitis in the observation group was significantly lower than that in the control group (P < 0.05). In terms of postoperative nutritional status, the ratio of plasma albumin level and body weight restored to operation at 12 and 24 weeks after operation in the observation group was significantly higher than that in the control group (P < 0.05). 3 months after the operation, the levels of CD3 +, CD4 + cell subsets, and CD4+/CD8+ index reflecting the recovery of immune ability in the observation group were significantly higher than those in the observation group (P < 0.05). The application of double-channel anastomosis in laparoscopic D2 radical gastrectomy for early proximal gastric cancer has a better effect on reducing complications and promoting postoperative recovery, which is of great application value.

Double tract reconstruction versus double flap technique: short-term clinical outcomes after laparoscopic proximal gastrectomy for early gastric cancer. Surg Endosc 2022; 36:5243-5256.

Abstract
BACKGROUND Laparoscopic proximal gastrectomy (LPG) is increasingly preferred for operative management of early gastric cancer, although there is no consensus on a standard reconstruction method after resection. Two popular methods used after LPG are double tract reconstruction (DTR) and double flap technique (DFT). This study assessed comprehensive clinical outcomes including quality of life (QoL) and body composition change 1 year after DFT and DTR. METHODS We retrospectively reviewed prospectively collected data from 51 to 18 patients who underwent DTR and DFT, respectively, between September 2014 and December 2018. Short-term surgical outcomes, presence of reflux esophagitis, nutritional supplementation, medications, nutritional status (laboratory results and body composition analysis), and QoL measured preoperatively and at 1 year postoperatively were compared between both groups. RESULTS Both groups did not differ significantly in clinicopathological characteristics. The DFT as compared to the DTR group required significantly longer time for anastomosis (79.4 vs. 60.9 min, p < 0.001) and use of fewer staplers (3.39 vs. 6.86, p < 0.001). While the presence of endoscopic reflux esophagitis and iron/vitamin B12 replacement were comparable, the DTR group showed a higher tendency of taking anti-reflux medications for reflux symptoms (DTR: 13.7% vs. DFT: 0.0%, p = 0.177). The DTR group lost significantly more weight (p = 0.038) and body fat (p = 0.009). QoL analysis showed significant deterioration in diarrhea, eating restriction, and taste problems in both groups (DTR group: p = 0.008, p < 0.001, p = 0.010, respectively, and DFT group: p = 0.017, p = 0.024, p = 0.034, respectively). However, only the DTR group showed significant deterioration in physical function (p = 0.009), role function (p = 0.033), nausea/vomiting (p = 0.041), appetite loss (p = 0.019), dysphagia (p = 0.001), pain (p = 0.025), and body image (p = 0.004). CONCLUSIONS Despite requiring a longer anastomosis time, performing DFT after LPG was shown to be an ideal reconstruction method in terms of better 1-year QoL and nutritional outcome. Further larger studies over longer postoperative periods are necessary to confirm our findings.

Potential Applicability of Local Resection With Prophylactic Left Gastric Artery Basin Dissection for Early-Stage Gastric Cancer in the Upper Third of the Stomach. J Gastric Cancer 2022; 22:184-196.

Abstract
Purpose Total or proximal gastrectomy of the upper-third early gastric cancer (u-EGC) often causes severe post-gastrectomy syndrome, suggesting that these procedures are extremely invasive for patients without pathologically positive lymph node (LN) metastasis. This study aimed to evaluate the clinical applicability of a stomach function-preserving surgery, local resection (LR), with prophylactic left gastric artery (LGA)-basin dissection (LGA-BD). Materials and Methods The data of patients with u-EGC (pathologically diagnosed as T1) were retrospectively analyzed. Total gastrectomy was performed in 30 patients, proximal gastrectomy in 45, and subtotal gastrectomy in 6; the LN status was evaluated assuming that the patients had already underwent LR + LGA-BD. This procedure was considered feasible in patients without LN metastases or in patients with cancer in the LGA basin. The reproducibility of the results was also evaluated using an external validation dataset. Results Of the 82 eligible patients, 79 (96.3%) were cured after undergoing LR + LGA-BD, 74 (90.2%) were pathologically negative for LN metastases, and 5 (6.1%) had LN metastases, but these findings were only observed in the LGA basin. Similarly, of the 406 eligible tumors in the validation dataset, 396 (97.5%) were potentially curative. Tumors in the lesser curvature, post-endoscopic resection status, and small tumors (<20 mm) were considered to be stronger indicators of LR + LGA-BD as all subpopulation cases met our feasibility criteria. Conclusions More than 95% of the patients with u-EGC might be eligible for LR + LGA-BD. This function-preserving procedure may contribute to the development of u-EGC without pathological LN metastases, especially for tumors located at the lesser curvature.

Abstract
Simple Summary For patients with early gastric cancer (EGC), a good prognosis is achieved by conventional standard gastrectomy with radical lymphadenectomy. However, postgastrectomy syndrome is often inevitable and results in decreased quality of life (QOL). To improve patients’ QOL, proximal gastrectomy instead of total gastrectomy and pylorus-preserving gastrectomy instead of distal gastrectomy have been widely accepted as function-preserving gastrectomies. Recently, personalized, minimized gastrectomy with sentinel node navigation surgery has been developed and is expected to be an ideal treatment option for patients with EGC. Herein, we review the indications, surgical techniques, and postoperative outcomes of function-preserving gastrectomy. Abstract Recently, minimally invasive (endoscopic or laparoscopic) treatment for early gastric cancer (EGC) has been widely accepted. However, a standard gastrectomy with radical lymphadenectomy is generally performed in patients with EGC who have no indications for endoscopic resection, and postgastrectomy dysfunction is one of the problems of standard gastrectomy. Function-preserving gastrectomy, such as proximal gastrectomy and pylorus-preserving gastrectomy, can be considered when attempting to preserve the patient’s quality of life (QOL) postoperatively. In addition, sentinel node navigation surgery for EGC has been applied in clinical practice in several prospective studies on function-preserving personalized minimized gastrectomy. In the near future, the sentinel lymph node concept is expected to form the basis for establishing an ideal, personalized, minimally invasive function-preserving treatment for patients with EGC, which will improve their postoperative QOL without compromising their long-term survival. In this review article, we summarize the current status, surgical techniques, and postoperative outcomes of function-preserving gastrectomy for EGC.

Indication of Proximal Gastrectomy for Advanced Proximal Gastric Cancer Based on Lymph Node Metastasis at the Distal Part of the Stomach. ANNALS OF SURGERY OPEN 2021; 2:e107. [PMID: 37637877 PMCID: PMC10455053 DOI: 10.1097/as9.0000000000000107] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2021] [Accepted: 10/07/2021] [Indexed: 12/24/2022] Open
Abstract
Objective To suggest the possible indication of proximal gastrectomy for advanced gastric cancer located at the upper third of the stomach. Background Proximal gastrectomy has been an alternative surgical procedure for early proximal gastric cancer due to its benefits for quality of life while maintaining oncological outcomes. However, the oncological safety of proximal gastrectomy for advanced tumors remains unclear. Methods We retrospectively reviewed data from 878 patients who underwent radical total gastrectomy from 2003 to 2018 for pathologic T2-T4 gastric cancer in the upper third of the stomach. We identified risk factors for lymph node metastasis at the distal part of the stomach, which was not dissected in proximal gastrectomy. Subsequently, we evaluated the metastasis rate and therapeutic value index of lymph nodes at the distal part of the stomach in patients with none of these risk factors. Results Multivariable analysis revealed that esophagogastric junction (EGJ)-tumor epicenter distance >30 mm, tumor size >70 mm, macroscopic type IV tumor, and serosal invasion were risk factors for lymph node metastasis at the distal stomach. In patients without risk factors, the therapeutic value index for any lymph nodes at the distal stomach was 0.8, suggesting that lymph node dissection could be omitted in these patients. Conclusions EGJ-tumor epicenter distance ≤ 30 mm, tumor size ≤ 70 mm, not a macroscopic type IV tumor, and no serosal invasion could be an indication of proximal gastrectomy for advanced gastric cancer located at the upper third of the stomach.

Abstract
PURPOSE This retrospective nationwide survey investigated the quality of life (QOL) of patients with esophagogastric junction cancer after gastrectomy using the Postgastrectomy Syndrome Assessment Scale-45. METHODS The Postgastrectomy Syndrome Assessment Scale-45 comprises 45 questions classified into symptoms, living status, and QOL domains. A total of 1950 gastrectomized patients with upper-third gastric or esophagogastric junction cancer returned the completed forms. Among them, 224 eligible patients with esophagogastric junction cancer were selected, including 86, 120, and 18 patients who underwent total gastrectomy, proximal gastrectomy (reconstruction-esophagogastrostomy: 56; double-tract method: 51), and other procedures, respectively. RESULTS The postoperative period was significantly shorter (47 ± 30 vs. 34 ± 30 months, p = 0.002), and the rates of early-stage disease and minimally invasive approaches significantly higher (both p < 0.001) in the proximal gastrectomy group than in the total gastrectomy group. Despite advantageous background factors for proximal gastrectomy, the postoperative QOL did not differ markedly between the groups. Compared to patients who underwent reconstruction with the double-tract method, patients who underwent esophagogastrostomy had significantly larger remnant stomachs but a similar QOL. CONCLUSION Even with total gastrectomy, a postoperative QOL comparable to that with proximal gastrectomy can be maintained. Clarifying the optimal reconstruction methods for proximal gastrectomy for esophagogastric junction cancer is warranted. TRIAL REGISTRATION This study was registered at the University Hospital Medical Information Network Clinical Trials Registry (UMIN-CTR; registration number: 000032221).

Abstract
OBJECTIVES This work aimed to find the association of mixed-type histology and prognosis of T2/T3 GC patients. METHODS Eligible T2/T3 gastric cancer patients at our institution were identified. The histological types and risk factors affecting OS were examined. Survival differences were assessed by log-rank tests and Kaplan-Meier curves. RESULTS The study identified 972 T2/T3 gastric cancer patients, including 283 differentiated-type patients, 544 undifferentiated-type patients and 145 mixed type. Mixed-type histology was associated with shorter 5-year OS (DT vs UDT vs MT:57.5% vs 44.9% vs 39.6%, P = 0.002). MT histology can be predictive for prognosis of T2/T3 GC patients (HR for OS: 1.386, 95% CI: 1.028-1.868, P = 0.032), and its malignant potential is not inferior to UDT. In the subgroup analysis, MT can potentially be independent risk factor for non-distal GC patients (P = 0.010). CONCLUSION This study reported that mixed histology could be regarded as a potential prognostic factor for T2/T3 gastric cancer patients, especially for those with non-distal cancer. MT patients have higher incidence of metastasis and recurrence and had poorer prognosis than those with pure histological type. It is necessary for MT patients to have preoperative pathological examination for accurate histologic classification, so as to make the comprehensive treatment strategies..

Ann Gastroenterol Surg 2021; 5:767-775. [PMID: 34755008 PMCID: PMC8560615 DOI: 10.1002/ags3.12486] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/18/2021] [Revised: 06/07/2021] [Accepted: 06/24/2021] [Indexed: 02/06/2023] Open
Abstract
AIM To treat upper third gastric cancer, proximal gastrectomy (PG), a function-preserving procedure, is recommended for early lesions when at least half the distal stomach can be preserved, while total gastrectomy (TG) is standard for locally advanced lesions. Oncological feasibility, when applying PG for such lesions, remains unknown. METHODS We reviewed patients undergoing TG for clinical (c) T2-T4 upper third gastric cancer between 2006 and 2015. Preoperative tumor locations were further classified into the cardia, fornix, and gastric body based on endoscopic findings. The metastatic rate and therapeutic value index for lymph node (LN) dissection were determined, and characteristics of patients with distal LN (No. 4d, 5, and 6) metastasis (DLNM) were reviewed. In addition, patients with pathological tumor invasion to the middle third (M) region were investigated. RESULTS We studied 167 patients. There were 8 (4.8%) with DLNM and 41 (24.6%) with pathological tumor invasion to the M region. As to regional stations, therapeutic indices for LN dissection at stations No. 4d, 5, 6, and 12a were zero or extremely low. No DLNM was detected in cT2 lesions or cT3/T4 lesions located within the cardia and/or the fornix. In addition, none of the lesions located within the cardia and/or the fornix by preoperative endoscopy extended to the M region in the pathological specimen. CONCLUSIONS For upper third gastric cancer, PG without No. 12a dissection might be acceptable for cT2-T4 lesions located within the cardia and/or the fornix when considering the risk of DLNM and cancer-positivity in the distal stump.

Abstract
BACKGROUND Whether proximal gastrectomy (PG) can be applied to patients with proximal advanced gastric cancer (AGC) remains controversial. We aimed to explore the oncological safety of PG for proximal AGC in this study. METHODS 452 patients undergoing surgery for proximal AGC in the Affiliated Cancer Hospital of Nanjing Medical University were enrolled in this study. 329 patients with AGC were finally analyzed, of which 254 patients underwent total gastrectomy (TG) and 75 patients underwent PG. We used propensity score-matched (PSM) analysis to reduce biases. RESULTS After PSM, 67 patients with proximal AGC were included in the PG group and TG group, respectively. The estimated 5-year OS rates for TG and PG group after PSM were 64.3% and 74.9%, respectively, and no significant difference in OS existed between the two groups (p = 0.275). Multivariate analysis showed that PG was not an independent prognostic factor. Incidence of metastasis in No.5 or 6 lymph node (LN) station was significantly higher in the patients with pathological T4 and Borrmann III tumors (9.9% and 10.6%) than those with pathological T2/3 and Borrmann I/II tumors (2.2% and 3.3%). No metastasis was observed in No.5 or 6 LN station in patients with pathological T2/3 tumors or Borrmann I/II tumors when tumor size was ≤4 cm. CONCLUSIONS PG is a reasonable choice for patients with selected proximal AGC, especially for those with tumors of size ≤4 cm, Borrmann type I/II, and pathological T2/3. Future prospective randomized trials should be conducted first in patients with these specific proximal tumors.

Proximal gastrectomy with gastric tube reconstruction or jejunal interposition reconstruction in upper-third gastric cancer: which offers better short-term surgical outcomes? BMC Surg 2021; 21:249. [PMID: 34218794 PMCID: PMC8256585 DOI: 10.1186/s12893-021-01239-7] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2021] [Accepted: 05/09/2021] [Indexed: 12/09/2022] Open
Abstract
Objective Proximal gastrectomy acts as a function-preserving operation for upper-third gastric cancer. The aim of this study was to compare the short-term surgical outcomes between proximal gastrectomy with gastric tube reconstruction and proximal gastrectomy with jejunal interposition reconstruction in upper-third gastric cancer. Methods A retrospective review of 301 patients who underwent proximal gastrectomy with jejunal interposition (JI) or gastric tube (GT) at Harbin Medical University Cancer Hospital between June 2007 and December 2016 was performed. The Gastrointestinal Symptom Rating Scale (GSRS) and Visick grade were used to evaluate postgastrectomy syndromes. Gastrointestinal fiberoscopy was used to evaluate the prevalence and severity of reflux esophagitis based on the Los Angeles (LA) classification system. Results The JI group had a longer operation time than the GT group (220 ± 52 vs 182 ± 50 min), but no significant difference in blood loss was noted. Compared to the GT group, the Visick grade and GSRS score were significantly higher. Reflux esophagitis was significantly increased in the GT group compared with the JI group. Conclusion Proximal gastrectomy is well tolerated with excellent short-term outcomes in patients with upper-third gastric cancer. Compared with GT construction, JI construction has clear functional advantages and may provide better quality of life for patients with upper-third gastric cancer.

Abstract
Purpose The aim of this study was to investigate the oncologic safety and identify potential candidates for proximal gastrectomy (PG) in upper third advanced gastric cancer (AGC) and esophagogastric junction (EGJ) cancers. Materials and Methods Among 5,665 patients who underwent gastrectomy for gastric adenocarcinoma between January 2011 and December 2017, 327 patients who underwent total gastrectomy with standard lymph node (LN) dissection for upper third AGC and Siewert type II EGJ cancers were enrolled. We analyzed the correlation between the metastatic rates of distal LNs (No. 4d, 5, 6, and 12a) around the lower part of the stomach and the clinicopathological characteristics. We identified subgroups with no metastasis to the distal LNs. Results The metastatic rate of distal LNs in proximal AGC and Siewert type II EGJ cancers was 7.0% (23 of 327 patients). On multivariate analysis, pathological T stage (P=0.001), tumor size (P=0.043), and middle third invasion (P=0.003) were significantly associated with distal LN metastases. Pathological ‘T2 stage’ (n=88), or ‘T3 stage with ≤5 cm tumor size’ (n=87) showed no metastasis in distal LNs, regardless of middle third invasion. Pathological T3 stage with tumor size > 5 cm (n=61) and T4 stage (n=91) had metastasis in the distal LNs. Conclusions In the upper third AGC and Siewert type II EGJ cancer, pathological T2 and small-sized T3 stage groups are possible candidates for PG in cases without distal LN metastasis. Further validation studies are required for clinical application.

Abstract
PURPOSE We investigated that double-tract reconstruction (DTR) may be more beneficial than esophagogastrostomy (EG) with fundoplication in terms of nutritional outcomes, focusing on loss of body weight. MATERIALS AND METHODS This study included 56 consecutive patients with early gastric cancer in the upper third of the stomach who received laparoscopic proximal gastrectomy, 39 underwent EG. In the 17 patients requiring resection of the abdominal esophagus or where the size of the remnant stomach was 50% or less, we performed DTR. RESULTS There was no significant difference in the rate of body weight change at 6 or 12 months, or in biochemical markers (hemoglobin, total protein, and albumin) at 12 months. However, 8 patients in the EG group had extreme body weight loss (≥20%) within 12 months. Conversely, in the DTR group, no patients had any extreme body weight loss. CONCLUSION DTR is useful after laparoscopic proximal gastrectomy, especially in terms of preventing extreme body weight loss.

Abstract
Early gastric cancer (EGC) has excellent postoperative survival outcomes; thus, one of the recent keywords in the treatment of EGC is "function-preserving gastrectomy (FPG)." FPG reduces the extent of lymphadenectomy and gastric resection without compromising the long-term prognosis. Proximal gastrectomy (PG) is an alternative to total gastrectomy (TG) for EGC in the upper-third of the stomach, in which the gastric reservoir, gastric acid secretion, and intrinsic factors are maintained. Distal gastrectomy (DG) with a small remnant stomach, namely subtotal gastrectomy (STG), is another option for upper EGC, where the function of the cardia and fundus is preserved. Pylorus-preserving gastrectomy (PPG) is a good alternative to DG for EGC in the middle-third of the stomach, where pyloric function is preserved. Following elucidation of the markedly low incidences of possible metastasis to lymph node stations where dissection is omitted, the oncological safety of these FPG procedures was clarified. Nutritional advantages of PG or STG over TG have been reported; however, the standardized reconstruction methods after PG are yet to be established, and it is important to devise methods to prevent postoperative gastroesophageal reflux and anastomotic complications regardless of the reconstruction method. Nutritional benefits of PPG compared with DG have also been clarified, in which reducing postoperative gastric stasis is important. For the further spread of these FPG procedures, several issues, such as precise evaluation of preserved function, confirmation of oncological safety, and standardization of the technique, should be addressed in future prospective randomized controlled trials.

Abstract
Background Currently, the surgical approach to adenocarcinomas of esophago-gastric junction (AEG) remains controversial. Function-preserving gastric surgeries are becoming more popular, with proximal gastrectomy with double-tract anastomosis being one of the most important for AEG. Meanwhile, with the increasing use of laparoscopic techniques in the treatment of gastric cancer, the safety and effectiveness of laparoscopic-assisted proximal gastrectomy with double-tract anastomosis for Siewert type II-III AEG need to be further clarified. Methods Data of patients with Siewert type II/III AEG was collected at our center from October 2010 to December 2019 were retrospectively analyzed. 61 patients underwent open proximal gastrectomy with double-tract anastomosis (OPG-DT group) and 52 underwent laparoscopic-assisted proximal gastrectomy with double-tract anastomosis (LAPG-DT group). The clinical features, surgery, and short-term outcomes of patients in these 2 groups were collected to assess the safety and feasibility of LAPG-DT. Results A total of 113 patients were analyzed, there were 98 males and 15 females. No death during the operation. The differences in the number of lymph nodes, time to first flatus time to first eating, postoperative hospital stay, Additional analgesics were not statistically significant between two groups. Although the operative duration of LAPG-DT group was significantly longer than that of the OPG-DT group [(217±61) vs. (161±14) min, P=0.000), while less blood loss and less stress in LAPG-DT group. Early and late postoperative complications were similar between two groups. Conclusions Although laparoscopic-assisted proximal gastrectomy with double-tract anastomosis requires long operative time, it is associated with less bleeding and milder stress. Therefore, it is a safe and feasible surgical method.

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.

Clinical outcomes of proximal gastrectomy for gastric cancer: A comparison between the double-flap technique and jejunal interposition. PLoS One 2021; 16:e0247636. [PMID: 33626086 PMCID: PMC7904176 DOI: 10.1371/journal.pone.0247636] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2020] [Accepted: 02/02/2021] [Indexed: 01/07/2023] Open
Abstract
Background The optimal reconstruction method after proximal gastrectomy (PG) has been debatable. Recent reports have shown that the double-flap technique (DFT) provides good outcomes in terms of postoperative nutritional status and quality of life. However, no study has compared the clinical outcomes of the DFT with other reconstruction methods. Here, we evaluated and compared the clinical outcomes between the DFT and jejunal interposition (JI) after PG for gastric cancer. Materials and methods The medical records of 34 consecutive patients who had undergone PG for upper third gastric cancer between January 2011 and October 2016 were reviewed retrospectively. The main factors investigated were surgical outcomes, postoperative nutritional status, symptoms, and endoscopic findings 1 year after surgery. Results Thirty-four patients were enrolled (DFT, 14; JI, 20). The operation time was similar between the two techniques (228 and 246 minutes for DFT and JI, respectively, P = 0.377), as were the rates of anastomotic complications (7% and 0% for DFT and JI, respectively, P = 0.412). Body weight loss was significantly lower in the DFT group than in the JI group (-8.1% vs -16.1%, P = 0.001). Total protein and albumin levels were higher in the DFT group than in the JI group (0% vs -2.9%, P = 0.053, and -0.3% vs -6.1%, P = 0.077, respectively). One patient in the DFT group and no patients in the JI group experienced reflux esophagitis (≥ grade B) (P = 0.393). Anastomotic strictures were not observed as postoperative complications in either group. Conclusions Surgical outcomes revealed that the DFT was safe and feasible, similar to JI. In terms of controlling postoperative body weight loss, the DFT is a better reconstruction technique than JI after PG.

Abstract
Background We invented a new antireflux anastomosis method for use in proximal gastrectomy for adenocarcinoma of the esophagogastric junction (AEG) and named it semi-embedded valve anastomosis (SEV). This study was conducted to compare and analyze the short-term efficacy and long-term prognosis of this anastomosis reconstruction method versus laparoscopic total gastrectomy (LTG). Methods We retrospectively analyzed the general data and surgical outcomes of patients with AEG who underwent three united laparoscopic proximal gastrectomy plus semi-embedded valve anastomosis (TULPG-SEV, N = 20) and LTG (N = 20) at our hospital from January 2015 to September 2017 and investigated the incidence of postoperative reflux esophagitis and postoperative nutritional status between the two groups. Survival analysis was also performed. Results The operative time (178.25 ± 15.41 vs 196.5 ± 21.16 min) and the gastrointestinal reconstruction time (19.3 ± 2.53 vs 34.65 ± 4.88 min) of the TULPG-SEV group were significantly less than that of the LTG group. There was no difference in intraoperative blood loss, length of hospital stay, and postoperative complications. There was no difference in the scores on the postoperative reflux disease questionnaires (RDQs) conducted 1 month (P = 0.501), 3 months (P = 0.238), and 6 months (P = 0.655) after surgery between the TULPG-SEV group and LTG group. Gastroscopy revealed 2 cases of reflux esophagitis (grade B or higher) in each group. The postoperative hemoglobin level was better in the TULPG-SEV group than in the LTG group, and the difference was most noticeable at 1 month after surgery (P = 0.024) and 3 months after surgery (P = 0.029). The levels of albumin and total protein were not significantly different between the groups. There were more patients with weight loss over 5 kg after surgery in the LTG group than in the TULPG-SEV group (P = 0.043). There was no significant difference in the 3-year overall survival rate between the two groups (P = 0.356). Conclusion SEV has a certain antireflux effect and can reduce the anastomosis time. Proximal gastrectomy may be better than total gastrectomy for maintaining postoperative hemoglobin levels and reducing weight loss.

Abstract
IMPORTANCE It is unclear whether proximal gastrectomy (PG) can replace total gastrectomy (TG), even in cases of advanced gastric carcinoma. OBJECTIVES To evaluate the oncologic safety of PG based on the lymph node (LN) metastasis rate and develop a selection diagram for PG eligibility. DESIGN, SETTING, AND PARTICIPANTS In this cohort study, a retrospective analysis of a prospective database of gastric carcinoma surgery was performed including procedures that took place between December 1, 2000, and December 31, 2015, in the National Cancer Center, Korea, a high-volume carcinoma center with a structured database and accurate long-term follow-up. Among 9952 patients who underwent surgery for gastric carcinoma, 2347 underwent TG. Six-hundred fifty-five (564 in a second statistical analysis) had gastric carcinoma in the upper third of the stomach. The inclusion criteria were age 18 to 85 years, histologically proven adenocarcinoma (any size or differentiation) located in the upper third of the stomach, curative R0 TG performed, and postoperative follow-up for at least 3 years. Exclusion criteria included Borrmann type 4 carcinoma, T4 category, use of neoadjuvant chemotherapy, and a history of other carcinomas. Data analysis was performed from December 1, 2019, to May 30, 2020. EXPOSURES Total gastrectomy and LN dissection. MAIN OUTCOMES AND MEASURES The primary end point was the rate of LN metastasis at LN stations 4d, 5, and 6, which are usually not dissected during PG. RESULTS Among the 655 study patients, the mean (SD) age was 57.7 (11.9) years, and 462 (70.5%) were men. Only those with poorly differentiated cT3 category carcinomas had an increased incidence of LN metastasis at stations 4d (2 of 32 [6.3%]) and 11d (T3N0: 2 of 22 [9.1%], T3N1: 3 of 27 [11.1%]), independent of tumor size. For cT1-T3N0/1M0 category carcinomas, the incidence of station 5 LN metastasis was 0, irrespective of tumor size and differentiation. The LN metastasis rate at stations 4d and 6 for cT1-T3N0/1M0 differentiated tumors was also 0. Tumor size greater than or equal to 4.1 cm was associated with significantly increased LN metastasis compared with tumors less than 4.1 cm (40.0% vs 20.4%, P = .001). CONCLUSIONS AND RELEVANCE The findings of this study suggest that PG can be safely performed for cT1-T2N0/1M0 tumors less than 4.1 cm in diameter that are located in the upper third of the stomach. The cT3N0/1M0-differentiated tumors less than 4.1 cm may also be eligible for PG, whereas poorly differentiated cT3 tumors and any cT4 or cN2/3 diseases require TG.

Abstract
BACKGROUND To investigate the safety and merits of laparoscopic proximal gastrectomy with double-tract reconstruction (LPG-DT) for Siewert type II and III adenocarcinoma of the esophagogastric junction (AEG). METHODS Retrospective analysis of the clinical data of 100 consecutive patients with Siewert II and III AEG treated at the Affiliated Tumor Hospital of Zhengzhou University from October 2010 to October 2019 was performed. Out of these patients, 69 underwent open proximal gastrectomy with double-tract reconstruction (OPG-DT), while 31 underwent LPG-DT. The clinicopathological characteristics, perioperative data, and short-term outcomes of the two groups were compared. A P value <0.05 was considered statistically significant. RESULTS Males accounted for 87% of all patients. Lymph nodes (LNs) count, time to first meal, postoperative length of stay, and postoperative complications were similar between the OPG-DT and LPG-DT group. flatus time was significantly shorter in the LPG-DT group (P<0.05), while the duration of operation was significantly shorter in the the OPG-DT group (P<0.001). Furthermore, the LPG-DT group has less blood loss, shorter flatus time, and lower postoperative-day-5 white blood cell (WBC) count and C-reactive protein (CRP) levels (P<0.05). CONCLUSIONS Although LPG-DT took longer to perform, its advantages of reduced blood loss and less surgical stress reflected on inflammatory markers supports an acceptable surgical option for Siewert II and III AEG.

Abstract
Aims: To addresses whether surgical procedure (proximal gastrectomy [PG] vs total gastrectomy [TG]) influences survival outcomes. Methods: Patients were selected from Surveillance, Epidemiology and End Results Program (SEER) database. Survival curve was used to evaluate the differences in overall survival (OS) and cancer-specific survival (CSS). Results: No significant difference was detected in OS and CSS time between PG and TG groups. Also, no significant differences were observed in OS and CSS times between the two groups with respect to clinical stage, tumor stage, node stage, age, gender and tumor differentiation. Tumor differentiation, tumor size, tumor stage, node stage and age were independent prognostic factors in patients with proximal gastric cancer. Conclusions: TG was not necessary for proximal gastric cancer patients, and PG may be considered as an ideal surgery approach.

Abstract
BACKGROUND Total gastrectomy and proximal gastrectomy (PG) are both surgical options for the treatment of Siewert type III adenocarcinoma of the esophagogastric junction (AEG). Currently there is no consensus on selecting which procedure to perform; in particular, there are few reports of long-term outcomes for patients with local advanced AEG. The aim of this study was to validate the usefulness of PG with double-tract reconstruction in Siewert type III AEG. METHODS The clinical data of patients with Siewert type III AEG underwent PG with double-tract reconstruction (PG-DT) or total gastrectomy with Roux-en-Y anastomosis (TG-RY) at our hospital between October 2010 and October 2018. According to the defined inclusion and exclusion criteria, 2,146 cases were enrolled in this study. A 1-to-1 propensity score matching (PSM) was performed to compare the short and long-term outcomes between the 2 groups. RESULTS The operation time was longer in the PG-DT group, and the proportion rates of complications and recovery time was similar in the 2 groups. The rates of maintaining bodyweight and free-fat mass index were significantly higher in patients who underwent PG-DT compared to those who underwent TG-RY. While complications, recovery time and survival are similar between two groups. CONCLUSIONS Regarding short-term outcomes, PG-DT seemed to be superior in terms of maintaining body weight and skeletal muscle compared to TG-RY, while both had similar complications. It was found that PG-DT enabled a potentially longer survival of pathological stage II and III Siewert type III AEG, although the finding was statistically insignificant. These results may help surgeons to determine the appropriate surgical approach and strategy for patients with early and locally advanced Siewert type III AEG.

Abstract
Background There is a high probability of gastroesophageal reflux after laparoscopic proximal gastrectomy for adenocarcinoma of the oesophagogastric junction (AEG). Various anti-reflux anastomotic methods are emerging in clinical practice; however, none of them have been widely accepted. We have innovated a new type of anti-reflux anastomotic method, named semi-embedded valve anastomosis. The aim of this study was to explore the feasibility and anti-reflux effect of the new anastomotic method. Methods The clinical data of 28 patients with Siewert II AEG who were treated by semi-embedded valve anastomosis were collected. The key point of the operation is to reconstruct a simulated valve and form an anti-reflux barrier similar to the physiological mechanism. The gastroesophageal reflux disease questionnaire (GerdQ) and classification of gastroesophageal reflux under electron microscopy were used to evaluate gastroesophageal reflux after the operation. Results The mean operative duration was 164.3 ± 19.0 min, the median intraoperative haemorrhage volume was 65 ml, the average number of lymph nodes dissected was 23 ± 2.6, the time for valve construction was 15.8 ± 3.2 min, the time for anastomotic reconstruction was 35.4 ± 4.8 min, the median time to first flatus was 3 d, and the median hospitalization duration was 12 d. There was one case of postoperative anastomotic stenosis. The GerdQ score [median (range)] was as follows: 2 (0–6), preoperation; 0 (0–8), 1 month postoperation; 2 (0–12), 3 months postoperation; and 3 (0–12), 6 months postoperation. The Wilcoxon signed-rank sum test was carried out at different times after the operation and the day before the operation, and the differences were not significant. There was one case of grade B gastroesophageal reflux according to the Los Angeles classification system among the gastrofibroscopic re-examination reports of 28 cases. Conclusion Semi-embedded valve anastomosis is safe and feasible after proximal gastrectomy for Siewert II AEG and has good anti-reflux effects.

Abstract
Background: We aimed to assess long-term survival between locally advanced proximal gastric cancer (LAPGC) patients who underwent proximal gastrectomy (PG) and those who underwent total gastrectomy (TG) to evaluate the optimal extent of resection and adjuvant therapy. Materials and Methods: Patients diagnosed with locally advanced proximal gastric adenocarcinoma were selected from the National Cancer Data Base (2004–2015) in America. Survival analysis was performed via Kaplan-Meier and Cox proportional hazards models. Results: A total of 4,381 eligible patients were identified, 1,243 underwent PG and 3,138 underwent TG. Patients in TG group had a poor prognosis (hazard ratio [HR] = 1.13, 95% confidence interval [CI]: 1.03–1.25) compared with those in PG group. Moreover, postoperative chemoradiation therapy was associated with improved overall survival compared to surgery alone (HR = 0.71, 95% CI: 0.53–0.97) in LAPGC patients who had PG, while preoperative chemotherapy (HR = 0.74, 95% CI: 0.59–0.92) was associated with improved survival among patients who had TG. Conclusions: Our study suggested that LAPGC patients underwent PG experienced better long-term outcomes than those underwent TG. It also suggested that multimodality treatment of LAPGC, including preoperative chemotherapy followed by TG or postoperative chemotherapy followed by PG, should be considered to achieve better long-term outcomes.

Abstract
The incidence of proximal gastric cancer has been increasing continuously. This status has prevailed despite the application of laparoscopic proximal gastrectomy as a surgical treatment for early proximal gastric cancer. The widespread adoption and standardization of this surgical procedure as the primary treatment for the abovementioned cancer has been hampered by the lack of consensus on the optimal reconstruction method after proximal gastrectomy. In addition, the oncological safety of proximal gastrectomy for advanced gastric disease remains unclear. We reviewed the English-language literature to clarify the current status of laparoscopic proximal gastrectomy in proximal gastric cancer. Japanese gastric cancer guidelines have suggested three types of reconstructions for proximal gastrectomy, namely, esophagogastrostomy, double-tract reconstruction, and jejunal interposition. Optimal reconstruction methods remain to be determined because of the lack of adequately performed and well-designed randomized controlled trials. The technical complexity and challenging implementation of reconstruction procedures have resulted in several complications with anastomoses. Multicenter randomized controlled trials are necessary to evaluate the various reconstruction methods and the oncological safety of laparoscopic proximal gastrectomy for advanced gastric disease.

Abstract
Proximal gastrectomy (PG) is one of the function-preserving surgical methods for the treatment of upper gastric cancer. Favorable postoperative results have been reported in comparison with total gastrectomy. However, because there are challenges, such as postoperative reflux esophagitis, anastomotic stenosis, and residual food, appropriate selection of a reconstruction method is crucial. Some methods include esophagogastric anastomosis, including simple esophagogastrostomy, tube-like stomach esophagogastrostomy, side overlap with fundoplication by Yamashita, and double-flap technique, and reconstruction using the small intestine, including double-tract methods, jejunal interposition, and jejunal pouch interposition. However, standard reconstruction methods are yet to be established. PG has also been employed in early gastric cancer of the upper third of the stomach, and indications have also been extended to esophagogastric junction cancer, which has shown an increase in recent years. Although many retrospective studies have revealed the functional benefits or oncological safety of PG, the characteristics of each surgical procedure should be understood so that an appropriate reconstruction method, with a reflux prevention mechanism and minimal postoperative injury, can be selected.
