RESUMO
INTRODUCTION: This study compared the short-term outcomes of older adult patients with locally advanced gastric cancer who underwent open distal gastrectomy (ODG) with those who underwent laparoscopic distal gastrectomy (LDG) using propensity score matching analysis. METHODS: Overall, 341 consecutive older adult patients aged 75 years with gastric cancer who underwent ODG or LDG between January 2013 and December 2020 were retrospectively assessed. Among them, 121 patients with locally advanced gastric cancer were included. To compare short-term outcomes, a 1:1 propensity score matching analysis was performed. RESULTS: After matching, 29 patients were included in both groups. Compared with the ODG group, the LDG group had a longer operative time (mean, 290 vs. 190 min; p < .0001) and lower estimated blood loss (mean, 39 vs. 223 mL; p < .0001). Overall postoperative complications of grade 2 and higher were observed in 2 (6.9%) and 12 (41%) patients in the LDG and ODG groups, respectively (p = .0046). Of these, the LDG group had a significantly lower incidence rate of infectious complications than the ODG group (3.4% vs. 27.6%; p = .025). Furthermore, in multivariate analysis, the laparoscopic approach was an independent protective factor against postoperative complications (p = .029). CONCLUSIONS: LDG is safe and feasible for locally advanced gastric cancer in patients aged ≥75 years. Moreover, it may be a promising alternative to ODG with better short-term outcomes, including significantly lower incidence rates of postoperative complications.

BACKGROUND: Preoperative chemotherapy with 5-fluorouracil and cisplatin (FP) followed by surgery has been considered a standard treatment for patients with stage II/III esophageal squamous cell carcinoma (ESCC) based on the results of a phase III trial (JCOG9907) in Japan. Subsequently, the phase III NExT trial (JCOG1109) revealed the survival benefit of the neoadjuvant DCF regimen, which adds docetaxel to FP, and it became a standard treatment. However, the long-term results and prognostic factors of neoadjuvant DCF therapy in the real world are unknown. METHODS: We retrospectively investigated 50 patients with ESCC treated with neoadjuvant DCF therapy from July 2012 to December 2017 at The University of Tokyo Hospital. RESULTS: Median overall survival (OS) and progression-free survival (PFS) were 32.3 [95% confidence interval (CI) 21.0-NA] and 10.0 months (95% CI 6.3-15.6), respectively. Median OS [not reached (95% CI 31.5-NA) vs. 21.4 months (95% CI 13.5-33.0); p = 0.028] and PFS [83.3 months (95% CI 6.4-NA) vs. 7.4 months (95% CI 6.0-12.8] were significantly longer in patients with an objective response than in non-responders. Of 44 surgical cases, median PFS tended to be longer in pathological lymph node metastasis-negative patients. Conversely, survival did not differ according to cStage (II/III vs. IV) or the average relative dose intensity (ARDI, ≥ 85% vs. < 85%). DISCUSSION: The response to neoadjuvant DCF therapy could predict patient prognosis. Additionally, pN+ tended to increase the recurrence risk, whereas cStage and ARDI did not influence survival.
RESUMO
PURPOSE: In this study, we assessed the relationship between remnant gastritis and muscle mass loss and then investigated the potential relationship between Helicobacter pylori (HP) infection and remnant gastritis and muscle loss. METHODS: We reviewed the medical records of 463 patients who underwent distal gastrectomy between January 2017 and March 2020. Of these patients, 100 with pStage I after laparoscopic surgery were included in this analysis. RESULTS: A multivariate analysis showed that the total Residue, Gastritis, Bile (RGB) classification score, which indicates the degree of gastritis, was significantly associated with the rate of change (rate of decrease) in the psoas muscle area (PMA) during the first 6 months after surgery (p = 0.014). Propensity score matching was performed according to HP infection, and the rate of change in the PMA and the degree of remnant gastritis in 56 patients were compared. Neither was significantly associated with HP infection. CONCLUSIONS: Remnant gastritis did contribute to psoas muscle mass loss during the initial 6 months after gastrectomy, and HP infection was not significantly associated with either remnant gastritis or psoas muscle mass loss. Nevertheless, the potential for HP eradication to prevent muscle loss and improve the survival prognosis for gastrectomy patients merits further research.

BACKGROUND: Laparoscopic gastrectomy is a common procedure for early gastric cancer treatment. Improving postoperative pain control enhances patient recovery after surgery. The use of multimodal analgesia can potentially enhance the analgesic effect, minimize side effects, and change the postoperative management. The purpose of this study was to evaluate and compare the efficacies of the use of patient-controlled intravenous analgesia with regular acetaminophen (PCIA + Ace) and patient-controlled thoracic epidural analgesia (PCEA) for postoperative pain control. METHODS: We retrospectively collected the data of 226 patients who underwent laparoscopic distal gastrectomy (LDG) with delta-shaped anastomosis between 2016 and 2019. After 1:1 propensity-score matching, we compared 83 patients who used PCEA alone (PCEA group) with 83 patients who used PCIA + Ace (PCIA + Ace group). Postoperative pain was assessed using a numeric rating scale (NRS) with scores ranging from 0 to 10. An NRS score ≥ 4 was considered the threshold for additional intravenous rescue medication administration. RESULTS: Although NRS scores at rest were comparable between the PCEA and PCIA + Ace groups, NRS scores of patients in the PCIA + Ace group during coughing or movement were significantly better than those of patients in the PCEA group on postoperative days 2 and 3. The frequency of additional rescue analgesic use was significantly lower in the PCIA + Ace group than in the PCEA group (1.1 vs. 2.7, respectively, p < 0.001). The rate of reduction or interruption of the patient-controlled analgesic dose was higher in the PCEA group than in the PCIA + Ace group (74.6% vs. 95.1%, respectively, p = 0.0002), mainly due to hypotension occurrence in the PCEA group. Physical recovery time, postoperative complication occurrence, and liver enzyme elevation incidence were not significantly different between groups. CONCLUSIONS: PCIA + Ace can be safely applied without an increase in complications or deterioration in gastrointestinal function; moreover, PCIA + Ace use may provide better pain control than PCEA use in patients following LDG.

BACKGROUND: Higher relative dose intensity (RDI) of chemotherapy improves the clinical outcomes of various cancers. The psoas muscle index (PMI) is related to sarcopenia, and patients with low PMI have worse prognoses. However, few studies have demonstrated its clinical relevance in gastric cancer. METHODS: This retrospective study included 188 stage II/III gastric cancer patients who had undergone curative gastrectomy between January 2013 and March 2017, 124 of whom had received postoperative S-1 adjuvant chemotherapy. RESULTS: Per receiver operating characteristic analysis, patients were divided into high and low RDI groups, between which relapse-free survival differed marginally significantly and disease-specific survival differed significantly. In patients who received adjuvant chemotherapy, multivariate analysis found that high RDI and low PMI reduction rate 1 year after surgery were significantly associated with better relapse-free survival. Low RDI can be predicted by a combination of low preoperative PMI and non-distal gastrectomy, whereas high PMI reduction rate at 1 year can be affected by non-distal gastrectomy. CONCLUSION: High RDI with preserved psoas muscle up to 1 year after gastrectomy may be associated with prognoses in gastric cancer requiring postoperative adjuvant chemotherapy. Since RDI and PMI reduction rate can be predicted preoperatively, respectively, interventional consideration is possible for optimal adjuvant therapy in gastric cancer.

BACKGROUND: Although the American Society of Anesthesiologists (ASA) score of 3 is relatively common in elderly patients, there have been few debates on the indications for gastrectomy in elderly gastric cancer (GC) patients with ASA3. Therefore, this study aimed to investigate gastrectomy's clinical relevance in elderly patients with GC and ASA3. METHODS: We retrospectively analyzed 228 consecutive elderly GC patients (aged ≥ 75 years) without prior treatments who underwent curative gastrectomy between 2013 and 2017. RESULTS: Thirty-three patients with ASA3 showed significantly poorer prognosis than those with ASA1 and 2 (p = 0.004). The multivariate Cox proportional hazards model showed that ASA3 (p = 0.021) and pStage (p = 0.007) were independent prognostic factors, respectively. Elderly GC patients with pStage III and ASA3 exhibited uniquely dismal prognosis (p < 0.001); however, several survivors were still confirmed. Postoperative complications (PCs) were only the final remnant independent prognostic factor (p = 0.020) among the 33 elderly GC patients with ASA3, where dead patients included cancer-specific and other deaths, especially pneumonia. PCs were independently associated with prognostic nutritional index (PNI) (< 42.7) in elderly GC patients, and the most frequent complication was pneumonia, which was significantly associated with ASA3 and marginally associated with PNI in a multivariate analysis. CONCLUSIONS: ASA3 has a dismal prognosis after curative gastrectomy in the elderly GC patients, but the number of survivors was confirmed. Curative gastrectomy is not considered contraindicated even in elderly GC with ASA3. Preoperative malnutrition is associated with PCs, which proposing preoperative nutritional intervention in the context of treatment strategy for the elderly GC patients with ASA3.

BACKGROUND AND PURPOSE: We investigated the impact of postoperative changes in the psoas muscle mass index (PMI) after gastrectomy and S1 adjuvant chemotherapy (AC) on the long-term outcomes of elderly patients with gastric cancer. METHODS: We reviewed the medical records of 228 patients aged over 75 years, who underwent distal, proximal, or total gastrectomy between January, 2013 and March 2017. Among these patients, 78 with pStage IIA-IIIC who survived for at least 1 year without recurrence after gastrectomy were the subjects of this analysis. RESULTS: The log-rank test using the cut-off value from the rate of change in PMI from 6 to 12 months after gastrectomy (late rate of decrease) showed significantly poorer prognosis for the group above the cut-off value for both overall survival (OS) and recurrence-free survival (RFS) (RFS: PMI decrease ≥ 1.55%, p < 0.001; OS: PMI decrease ≥ 1.55%, p < 0.001). Patients with a relative dose intensity of S1 below 68.7% and a late rate of decrease in PMI above 1.55% were found to have a poor prognosis. CONCLUSION: It is necessary to prevent decline in the PMI of elderly patients from 6 months after gastrectomy and to administer adjuvant chemotherapy with about two-thirds or more RDI of S1 to improve their survival prognosis.

BACKGROUND: Little is known about the disadvantages of the coronavirus disease 2019 (COVID-19) pandemic in patients with gastric cancer. This study aimed to examine the negative impact of the COVID-19 pandemic on patients with gastric cancer in the first era in Japan. METHODS: This retrospective study included 725 patients diagnosed with gastric cancer who visited our hospital between April 2019 and March 2021. The number of patients and their characteristics before and during the COVID-19 pandemic were compared. RESULTS: The number of patients diagnosed with gastric cancer during the COVID-19 pandemic decreased by 26.2% (from 417 to 308; p = 0.013) compared to that before the COVID-19 pandemic. There was a significant decrease in cStage I cancer and an increase in cStage III cancer (p = 0.004). Patients were often symptomatic (p = 0.029), especially those with stenosis-related symptoms (p < 0.001) and longer symptom duration (p < 0.001). The number of endoscopic resections was decreased by 34.8% (p = 0.005). The number of total gastrectomy was higher than that of partial gastrectomy (p = 0.021). The median time to treatment was significantly shorter (p < 0.001). CONCLUSIONS: In Japan, delays diagnosing patients with gastric cancer, probably due to refraining from consultation, may have resulted in an increase in the diagnosis of advanced-stage cancer. Moreover, an increasing proportion of patients required more invasive gastrectomy. Therefore, it may be necessary to educate patients not to refrain from consultation, even during the COVID-19 pandemic, as it can have a negative impact on treatment, policy decision, and prognosis of gastric cancer.

PURPOSE AND BACKGROUND: Gastrectomy for gastric cancer in overweight patients is associated with a high incidence of postoperative complications and difficulties in achieving adequate lymph node dissection. We conducted this study to compare the outcomes of laparoscopic and open distal gastrectomy (ODG) for gastric cancer in overweight Japanese patients. METHODS: This retrospective study analyzed data from 180 patients with a body mass index ≥ 25 who underwent distal gastrectomy for pStage I-III gastric cancer. Postoperative complications, the number of harvested lymph nodes, and long-term survival were compared between ODG and laparoscopic distal gastrectomy (LDG). RESULTS: Postoperative complications of Clavien-Dindo (CD) grade ≥ 2 and ≥ 3 were significantly higher after ODG than after LDG (p < 0.001 and p = 0.004). Multivariate analysis identified age and ODG as factors related to complications of CD ≥ 2 (p = 0.014 and 0.002). The number of harvested lymph nodes at region 4sb was significantly higher in LDG for patients with pStage III disease. The 5-year lymph node recurrence-free survival tended to be better in LDG; however, no difference was found between ODG and LDG at any pathological stage. There were no significant differences in the 5-year overall and recurrence-free survival rates after ODG vs. LDG. CONCLUSIONS: LDG for gastric cancer appears to be associated with a lower incidence of postoperative complications than ODG, without compromising long-term survival, even for overweight patients.

BACKGROUND: Although the novel coronavirus disease 2019 did not lead to a serious medical collapse in Japan, its impact on treatment of oesophageal cancer has rarely been investigated. This study aimed to investigate the influence of the pandemic on consultation status and initial treatment in patients with primary oesophageal cancer. METHODS: A retrospective study was conducted among 546 patients with oesophageal cancer who visited our hospital from April 2018 to March 2021. Pre-pandemic and pandemic data were compared with the clinical features, oncological factors and initial treatment as outcome measures. RESULTS: Diagnoses of oesophageal cancer decreased during the early phase of the pandemic from April to June (P = 0.048); however, there was no significant difference between the pre-pandemic and pandemic periods throughout the year. The proportion of patients diagnosed with distant metastases significantly increased during the pandemic (P = 0.026), while the proportion of those who underwent initial radical treatment decreased (P = 0.044). The rate of definitive chemoradiotherapy decreased by 58.6% relative to pre-pandemic levels (P = 0.001). CONCLUSIONS: Patients may have refrained from consultation during the early phase of the coronavirus disease 2019 pandemic. The resultant delay in diagnosis may have led to an increase in the number of patients who were not indicated for radical treatment, as well as a decrease in the number of those who underwent definitive chemoradiotherapy. Our findings highlight the need to maintain the health care system and raise awareness on the importance of consultation.

PURPOSE: Sarcopenia is common in elderly gastrectomized patients and a known risk factor for postoperative complications and poor overall survival. However, the long-term outcomes of skeletal muscle loss after gastrectomy and the differences in outcomes of different gastrectomy procedures remain unclear. METHODS: The subjects of this retrospective study were 136 patients who underwent various gastrectomy procedures for early gastric cancer, namely: total gastrectomy (TG; n = 20), proximal gastrectomy (PG; n = 16), distal gastrectomy (DG; n = 60), and pylorus-preserving gastrectomy (PPG; n = 40). Skeletal muscle volume (SMV), calculated as the skeletal muscle index (SMI), was measured using cross-sectional computed tomography (CT) scans preoperatively and then 1, 2, and 3 years after gastrectomy. RESULTS: Sarcopenia developed from 2 years onwards in all the patients who underwent TG. The SMI and sarcopenia prevalence after gastrectomy deteriorated over time. Multivariate analysis revealed that TG and PG were significant risk factors for skeletal muscle loss in postoperative years 1 and 3. A decrease in the SMI after TG or PG was most remarkable in elderly patients. CONCLUSIONS: The type of gastrectomy affects skeletal muscle loss in the long term. Elderly patients who undergo TG or PG are at high risk of severe skeletal muscle loss.

PURPOSE: Bleeding from unresectable gastric cancer is a localized condition that adversely affects quality of life. Radiotherapy can be used to treat gastric cancer bleeding when surgery, endoscopic treatment, and intravascular embolization are ineffective. This study evaluated the utility of radiotherapy for unresectable hemorrhagic gastric cancer. METHODS: We retrospectively analyzed data from 33 patients with gastric cancer bleeding who underwent palliative radiotherapy in our hospital between April 2013 and May 2020. In this study, successful hemostasis was defined as > 1 month after starting radiotherapy with the patient alive and showing no need for blood transfusion, no drop in hemoglobin, and no evidence of melena or hematemesis. RESULTS: Patients comprised 26 men (79%) and 7 women (21%), with a median age of 71 years (range, 41-78 years). Hemostasis was achieved in 24 patients (73%). Thirty-two patients (94%) have been discharged home or transferred to the hospice. Patients with successful hemostasis from radiotherapy showed significantly longer overall survival than patients with unsuccessful hemostasis (p = 0.0026). No toxicities of grade 2 or more were encountered. CONCLUSIONS: This retrospective study found that palliative radiotherapy for gastric cancer bleeding was useful and safe and can improve remaining quality of life in patients with poor prognosis.

BACKGROUND: Surgery is still the mainstay of radical treatment for resectable esophageal cancer (EC). It is apparent that the presence or spread of lymph node metastasis (LNM) is a powerful prognostic factor in patients with EC who are eligible for curative treatment. Although the importance and efficacy of lymph node dissection in radical esophagectomy have been reported, the clinical or prognostic relevance of specific metastatic patterns within the mediastinal cavity and abdomen remains unclear. METHODS: We retrospectively analyzed the association of postoperative survival with clinical mediastinal LNM (cMLNM) and abdominal LNM (cALNM) in 157 patients who underwent radical EC surgery at our hospital between May 2012 and March 2018. RESULTS: A significant difference in cause-specific survival (CSS) was observed between patients with and without cALNM (log-rank p = 0.000). A multivariate Cox regression analysis revealed that cALNM and thoracic surgery (mediastinal lymphadenectomy via conventional open right thoracotomy or video-assisted thoracoscopic surgery) independently predicted CSS (p = 0.0007 and 0.021, respectively). Moreover, a significant difference in systemic recurrence-free survival was observed between those with and without cALNM (log-rank p = 0.000). Multivariate Cox regression analysis revealed that cALNM and sex independently predicted systemic recurrence-free survival (p = 0.000 and 0.015, respectively). CONCLUSION: cALNM was an independent poor prognostic factor for CSS after EC surgery. It may also be an independent prognostic factor for postoperative systemic recurrence, which can shorten the CSS. For patients with cALNM-positive EC who have a high potential risk of systemic metastases, more extensive treatment besides the conventional perioperative systemic chemotherapy may be necessary.

PURPOSE: There are various reconstruction methods for Laparoscopic proximal gastrectomy (LPG), such as esophagogastrostomy (EG), double-tract reconstruction, and jejunal interposition. We have performed EG using a circular stapler (OrVil) from 2013 and using a linear stapler from 2017. The aim of this retrospective study was to clarify which stapler is better for EG for LPG. METHODS: The data of 84 patients who underwent EG for LPG between January 2013 and September 2019 were analyzed. EG with fundoplication was done using a circular stapler (OrVil) in 45 patients (CS group) and a linear stapler in 39 patients (LS group). The patients' medical records were reviewed. Clinical symptoms were obtained by interview at each outpatient consultation. All patients underwent postoperative 1-year follow-up endoscopy. To minimize bias between the two groups, propensity scores were calculated using a logistic regression model. After propensity-score matching, 60 patients (30 in the CS group and 30 in the LS group) were studied. RESULTS: Patient characteristics, operative outcomes were similar in two groups. Anastomotic leakage occurred in one patient (3.3%) in both groups. Anastomotic stenosis occurred in five patients (16.7%) in the CS group and two patients (6.7%) in the LS group. The rate of patients with severe reflux esophagitis (grade C or D) was significantly lower in the LS group (3.4%) than in the CS group (26.7%) (p = 0.026). CONCLUSIONS: EG with a linear stapler could reduce the risk of severe reflux esophagitis, and it could be a safe and feasible anastomosis for patients after LPG.

PURPOSE: This study aimed to clarify the relationship between obesity and postoperative C-reactive protein (CRP) and assess the usefulness of obesity status-adjusted CRP levels for predicting early complications following laparoscopic gastrectomy for gastric cancer. METHODS: This study retrospectively analyzed 527 patients who underwent laparoscopic gastrectomy for gastric cancer between January 2013 and March 2019. Patients were classified into three groups according to body mass index (BMI): BMI < 20; BMI ≥ 20 to < 25; and BMI ≥ 25. The correlation between BMI and perioperative CRP was investigated in 447 patients, excluding 80 with postoperative complications. The optimal CRP cutoff value of Clavien-Dindo (CD) grade ≥ 3 for predicting severe complications for each group was determined. RESULTS: BMI was significantly correlated with CRP on postoperative day (POD) 3 (p < 0.001) in 447 patients without complications. According to the receiver operating characteristic curve analysis, CRP cutoff values on POD 3 for predicting severe complications were 92.4, 111.1, and 171.9 in the BMI < 20, BMI ≥ 20 to < 25, and BMI ≥ 25 groups, respectively. In multivariate analysis for CD grade ≥ 3 complications, cardiac history and POD 3 CRP levels higher than the adjusted cutoff were identified as independent factors significantly associated with severe complications (p = 0.021 and 0.015, respectively). CONCLUSION: CRP cutoff values on POD 3 adjusted for BMI were useful for predicting severe complications in gastrectomy for gastric cancer.

Various innovative robotic systems have been developed to improve surgery precision. The Senhance Surgical System (SSS) is a digital laparoscopic system offering eye tracking and haptic feedback. Several reports have described application of the SSS to general surgeries, including cholecystectomy and colectomy. However, use of the SSS for gastric tumor has not been reported. We experienced a case of laparoscopic local gastrectomy (LLG) for gastrointestinal stromal tumor (GIST) with the SSS. A 74-year-old man diagnosed with GIST underwent LLG with the SSS. Operation, docking, and console times were 117, 11, and 59 minutes, respectively. No perioperative complications were encountered. This study is the first to report LLG for GIST with the SSS. LLG with the SSS was safe and feasible. The SSS can use reusable forceps and contribute to reducing medical costs. The development of instruments is also progressing, and various kinds of surgery are likely to be indicated.

Esophageal gastrointestinal stromal tumors (E-GIST) are very rare tumors, and there is no consensus regarding the optimal surgical approach for E-GISTs. Here, we report a case of a large E-GIST that was resected via video-assisted thoracoscopic surgery (VATS) and hand-assisted laparoscopic surgery (HALS). When examining for comorbidities of myasthenia gravis using computed tomography, a 7-cm-sized tumor was detected in the lower esophagus of a 68-year-old woman. Further examination revealed the tumor to be an E-GIST with high malignant potential, and thus, esophagectomy was performed. The hybrid procedure for VATS and HALS techniques was safe and minimally invasive for this E-GIST that required esophagectomy. Thus, esophagectomy with VATS and HALS is thought to be a reasonable surgical option for resecting large E-GISTs, for which enucleation is not recommended.

BACKGROUND: In esophageal cancer, long-term outcomes of minimally invasive surgery using endoscopic surgery are currently being verified. However, most trials have compared thoracic procedures; few studies have focused on the abdominal procedures, which are important for lymph node dissection in radical esophageal cancer surgery. Hand-assisted laparoscopic surgery (HALS) is a simple and minimally invasive procedure. Although HALS superiority in short-term outcomes has been reported, its oncological safety in esophageal cancer remains unclear. Therefore, we retrospectively evaluated oncological safety of HALS compared with that of conventional open laparotomy (OL) in radical surgery for thoracic and abdominal esophageal cancer. METHODS: We retrospectively analyzed the postoperative survival in 142 patients who underwent radical esophageal cancer surgery at our hospital between May 2012 and May 2017, with and without propensity score matching (PSM) between groups. RESULTS: Before PSM, OL (n = 65) and HALS (n = 77) groups differed significantly in overall survival (OS) (3-year OS rate: 74.2% and 87.3%, respectively; log-rank p = 0.040). Additionally, clinical abdominal lymph node metastasis (cALNM) independently predicted OS (p = 0.031). After PSM, the OL and HALS groups did not differ significantly in OS (3-year OS rate: 80.5% and 89.8%, respectively; log-rank p = 0.716). There was no statistically significant difference in abdominal-specific recurrence-free survival between the OL and HALS group before and after PSM. CONCLUSION: HALS may be a well-accepted procedure for radical esophagectomy in esophageal cancer, with oncological safety, including local control specific to the abdomen, comparable to that of the conventional OL.

PURPOSE: In esophageal cancer surgery, the significance of preserving the azygos arch during thoracoscopic esophagectomy remains unknown. To determine the significance, we examined the difference in postoperative courses between patients who underwent an azygos arch-preserving technique and patients whose azygos arch had been dissected. METHODS: We retrospectively analyzed 119 patients with esophageal cancer who underwent thoracoscopic esophagectomy from January 2017 to December 2019. Statistical tests, including univariate or multivariate analyses and propensity score-matched analysis, were performed focusing on changes in fluid balance caused by the preservation of the azygos arch. RESULTS: The azygos arch was preserved in 65 patients and dissected in 54 patients. Urine output on postoperative day 2 was higher, and the IN-OUT balance on postoperative day 2 or accumulated IN-OUT balance up to postoperative day 2 tended to be lower in the azygos arch-preserving group than in the dissected group. The azygos arch-preserving technique did not affect the number of dissected mediastinal lymph nodes. CONCLUSION: The azygos arch-preserving technique during thoracoscopic esophagectomy facilitated postoperative refilling and avoided postoperative fluid excess. This technique might be a novel minimally invasive option for an otherwise highly invasive esophageal cancer surgery.

We report the case of a 68-year-old male with EGJ cancer, who was treated with palliative radiotherapy for persistent bleeding, and for whom, pCR was ultimately obtained by chemotherapy. Chemotherapy was planned to treat the EGJ cancer with intramural metastasis of the esophagus, but anemia due to persistent bleeding from the tumor was noted. Even with frequent blood transfusions, the anemia was difficult to control. Palliative radiotherapy was performed at 30 Gy/10 Fr for hemostasis, followed by chemotherapy. After approximately 9 months of chemotherapy, reduction of the primary tumor, a metastatic lymph node, and disappearance of the intramural metastasis of the esophagus were noted, and conversion surgery was performed. In the final histopathological examination, pCR was obtained. Radiotherapy for persistent bleeding from advanced gastric cancer is a minimally invasive treatment, and therefore could be an effective treatment to enable chemother- apy without any loss of compliance.
