RESUMO
Emergency surgery for a hiatal hernia (HH) is uncommon. However, mediastinal gastric perforation may occasionally present as the initial symptom of HH and demonstrate high mortality rates. Managing mediastinal gastric perforation in HH has no established standard surgical technique, and the selection of surgical techniques may be challenging. A 78-year-old female patient was referred to our department because of an upper gastrointestinal perforation in HH based on computed tomography (CT) results. Determining the possibility of esophageal perforation and intrathoracic penetration was difficult according to CT results alone, and whether a transthoracic or transabdominal approach was preferable. We diagnosed the patient with a mediastinal gastric perforation in HH without intrathoracic penetration based on an additional gastrointestinal contrast study and a right thoracentesis. We treated the patient with laparotomy, involving the perforation site and esophageal hiatus closure and gastropexy. Postoperatively, the patient experienced complications associated with delayed gastric emptying and aspiration pneumonia. Fortunately, no severe infections, such as residual abscess formation or empyema, were observed, and the recovery progressed favorably. Mediastinal gastric perforation should be considered a differential diagnosis for elderly patients with sudden-onset chest pain and dyspnea, and the threshold for imaging should be lowered. Identifying the perforation site and the presence of intrathoracic penetration based on preoperative results is useful for determining the appropriate surgical technique. Postoperative quality of life to the extent feasible needs to be considered, as the selection of surgical technique may cause subsequent recurrence or reflux symptoms.
RESUMO
PURPOSE: Cancer cachexia leads to poor outcomes, especially for patients with advanced stage disease. The cachexia index (CXI), a novel biomarker for cancer cachexia, has been identified as a prognostic indicator for several malignancies. The present study aimed to clarify the prognostic significance of the CXI for patients with recurrent pancreatic cancer. METHODS: This retrospective study enrolled 113 patients diagnosed with recurrence following pancreatectomy for pancreatic cancer, to analyze the association between the CXI and prognostic survival. RESULTS: The 2-year overall survival rate and median survival of all patients were 28.5% and 12.6 months, respectively. The 2-year overall survival curve in the high CXI group was significantly better than that in the low CXI group (p < 0.001). The rate of chemotherapy after recurrence was significantly lower in the low CXI group than in the high CXI group (p = 0.002). Multivariate analysis identified the CXI as an independent prognostic factor for patients with recurrent pancreatic cancer (p = 0.011). CONCLUSIONS: The CXI proved useful for predicting the post-recurrence prognosis of patients with recurrent pancreatic cancer. Patients with a low CXI at the time of recurrence have poorer prognostic outcomes than those with a high CXI.
RESUMO
Intraperitoneal (IP) chemotherapy with paclitaxel (PTX) for gastric cancer (GC) with peritoneal metastasis (PM) is considered a promising treatment approach, however, there are no useful biomarkers to predict the efficacy of IP therapy. We examined the association between intra-peritoneal exosomes, particularly exosomal micro-RNAs (exo-miRNAs), and IP-chemo sensitivity. MKN45 cells that were cultured with intra-peritoneal exosomes from patients who did not respond to IP therapy with PTX (IPnon-respond group) exhibited resistance to PTX compared with exosomes from responding patients (IPrespond group) (p = 0.002). A comprehensive search for exo-miRNAs indicated that miR-493 was significantly up-regulated in exosomes from the IPnon-respond group compared with those collected from the IPrespond group. The expression of miR-493 in PTX-resistant MKN45 cells (MKN45PTX-res) was higher compared with that in MKN45. In addition, MKN45PTX-res cells exhibited lower MAD2L1 gene and protein expression compared with MKN45. Finally, miR-493 enhancement by transfection of miR-493 mimics significantly down-regulated MAD2L1 expression in MKN45 cells and reduced PTX sensitivity. Our results suggest that intra-peritoneal exo-miR-493 is involved in chemoresistance to PTX by downregulating MAD2L1 in GC with PM. Exo-miR-493 may be a biomarker for chemoresistance and prognosis of GC patients with PM and may also be a promising therapeutic target.

This study aimed to investigate the prognostic relationship between relative dose intensity (RDI) of adjuvant S-1 chemotherapy and psoas muscle mass volume (PMV) in patients with resected pancreatic ductal adenocarcinoma. We enrolled 105 patients with histologically confirmed pancreatic ductal adenocarcinoma who had undergone pancreatectomy. Adjuvant S-1 chemotherapy was administered to 72 (68.6%) of the 105 patients and not to the remaining 33 patients. Patients who received adjuvant S-1 chemotherapy were stratified into high- and low-RDI groups by the cutoff value for RDI. Five-year overall survival (OS) and relapse-free survival (RFS) rates were significantly higher in the high- than in the low-RDI group. Similarly, both the 5-year OS and RFS rates were significantly greater among patients in the high-PMV group than among patients in the low-PMV group. The RDI was an independent prognostic factor in our study patients. Furthermore, patients who received adjuvant S-1 chemotherapy were stratified into 3 groups: those with both high RDI and high-PMV, Group A; those with either high RDI or high PMV (but not both), Group B; and those with both low RDI and low-PMV, group C. There were statistically significant differences in 5-year OS and RFS between 3 patient groups (5-year overall survival: Pâ =â .023, 5-year relapse-free survival: Pâ =â .001). The area under the curve for the combination of RDI and PMV (0.674) was greater than that for RDI alone (0.645). A sufficient dosage of adjuvant S-1 chemotherapy is important in improving survival of patients with resected pancreatic ductal adenocarcinoma. A combination of RDI and PMV may predict the prognosis of patients with resected pancreatic ductal adenocarcinoma more effective than RDI alone.

PURPOSE: This study investigated the prognostic value of the geriatric nutritional risk index (GNRI) in patients undergoing curative gastrectomy for remnant gastric cancer (RGC). METHODS: This multicenter retrospective study included 105 patients with RGC of ≥ 65 years of age who underwent curative gastrectomy at 10 institutions in Japan between January 2000 and December 2016. Postoperative complications, overall survival (OS), and disease-specific survival (DSS) were analyzed. RESULTS: Receiver operating curve analyses indicated that the optimal cutoff value of the GNRI for OS was 95.4. Patients were categorized into high and low GNRI groups based on the optimal GNRI cutoff value. The GNRI was significantly correlated with body mass index (p < 0.001), amount of bleeding (p = 0.021), Clavien-Dindo grade 5 postoperative complications (p = 0.040), death caused by primary disease (p = 0.010), and death caused by other diseases (p = 0.002). The OS and DSS were significantly worse in the low GNRI group. A low GNRI and T3 or deeper tumor invasion were independent prognostic factors for OS and DSS. CONCLUSIONS: The GNRI is a promising predictor of both short- and long-term outcomes in older patients with RGC.
RESUMO
Understanding anatomical anomalies of the branch of the celiac artery for safe gastrectomy is important. We report a case of laparoscopic distal gastrectomy with D1+ lymph node dissection for early gastric cancer with a vascular anatomical anomaly of the celiac artery. A 45-year-old woman was referred to our hospital because of early gastric cancer. Computed tomography showed an anatomical variation of the gastroduodenal artery, which branched from the celiac artery. The celiac artery also branched into the left gastric artery, the splenic artery, and the common hepatic artery. Preoperative understanding of an unusual branch of the celiac artery enabled a safe laparoscopic surgery. There were no postoperative complications. The Adachi classification or Michel classification is used for an anatomical anomaly of the celiac artery, but to the best of our knowledge, this case has not been previously classified and is the first reported case.

BACKGROUND AND PURPOSE: Older patients are more likely to encounter difficulties receiving chemotherapy, but the factors involved in the continuation of chemotherapy in these patients remain unclear. We investigated the importance of muscle mass as a factor involved in delivering a sufficient dose of postoperative S-1 adjuvant chemotherapy (ACT) to older patients with gastric cancer. METHODS: The subjects of this study were 79 patients aged ≥ 65 years with stage II/III gastric adenocarcinoma, who underwent curative gastrectomy and received S-1 ACT. RESULTS: The overall median relative dose intensity (RDI) was 75.0% (18.8-93.5%). Patients were divided into two groups for receiver operating characteristic analysis according to the cutoff value. Significantly more patients in the high skeletal muscle index (SMI) group achieved > 62% RDI of S-1 ACT (p = 0.03). Conversely, more patients in the low SMI group suffered from S-1-induced nausea (p = 0.03) and discontinued chemotherapy because of adverse events (p = 0.02). Multivariate analysis identified low SMI as an independent factor for insufficient S-1 dose delivery (p = 0.03, hazard ratio = 2.87). CONCLUSION: Preoperative SMI is an indicator of the low-dose intensity of S-1 ACT in older patients following curative gastrectomy.

PURPOSE: To investigate the prognostic utility of the cachexia index (CXI) in unresectable advanced gastric cancer (UAGC). METHODS: The relationship between CXI and the outcomes was evaluated in 102 patients with UAGC who had received first-line palliative 5-fluorouracil-based chemotherapy between January 2012 and December 2021. RESULTS: The median survival time (MST) from first-line chemotherapy initiation was 16.2 months, and the cohort included 60 and 42 patients with high and low CXIs, respectively, based on the optimal CXI cutoff. The rates of patients with a performance status score of 0, recurrence, third-line chemotherapy, and all grade 3-4 side effects, including febrile neutropenia (FN), were significantly higher in the CXIhigh group than in the CXIlow group. The prognosis based on MST was significantly better in the CXIhigh group than in the CXIlow group (22.5 vs. 11.6 months, p < 0.001). According to a multivariate analysis, a low CXI and performance status score of 1-2 were poor prognostic factors. CONCLUSIONS: Patients with UAGC and a low CXI had poorer prognoses and more frequent grade 3-4 side effects, including FN, than those with a high CXI. Patients with UAGC and a low CXI should be carefully managed to control for side effects to receive subsequent treatment.

BACKGROUND/AIM: Chemotherapy is the standard treatment for patients with unresectable gastric cancer (UGC); however, the survival outcomes are poor. This study investigated the predictive values of skeletal muscle mass (SMM) index (SMI) before second-line chemotherapy and the survival outcomes of patients with UGC. PATIENTS AND METHODS: A total of 79 patients diagnosed with UGC at our hospital who received at least second-line palliative chemotherapy were included. The cross-sectional SMM at the third lumbar vertebra was obtained before second-line chemotherapy. SMI was defined as the muscle area normalized by height squared (m2), and SMI before second-line chemotherapy was defined as 2ndSMI. RESULTS: Using 2ndSMI for men and women (35.4 and 31.7 cm2/m2, respectively) as the cutoff value, patients were divided into high (2ndSMIHigh; n=54) and low (2ndSMILow; n=25) 2ndSMI groups. The number of patients receiving fourth-line chemotherapy was significantly higher in the 2ndSMIHigh group than in the 2ndSMILow group (p=0.039). The overall survival time after the start of second-line chemotherapy was significantly higher in the 2ndSMIHigh group than in the 2ndSMILow group (p=0.008). The incidence of grade 3 or 4 side effects was significantly higher in the 2ndSMILow than in the 2ndSMIHigh group (p=0.028). The multivariate analysis identified 2ndSMI as independent prognostic factor after the start of second-line chemotherapy. CONCLUSION: The 2ndSMILow group had a significantly worse prognosis and significantly less conversion to fourth-line chemotherapy than the 2ndSMIHigh group. Moreover, 2ndSMILow was associated with grade 3 or 4 side effects of second-line chemotherapy.

BACKGROUND/AIM: Preoperative osteopenia, defined as low bone mineral density, is a prognostic factor in patients with digestive tract cancers, including gastric cancer (GC). However, the correlation between preoperative osteopenia and GC in elderly patients is unclear. PATIENTS AND METHODS: We enrolled 251 patients who had undergone curative surgery for histopathologically diagnosed gastric adenocarcinoma from January 2008 to December 2012. Patients were classified into the non-elderly group (n=169) and the elderly group (n=82). Bone mineral density was calculated as the average pixel density (Hounsfield units) within a circle of the mid-vertebral core at the bottom of the 11th thoracic vertebra on preoperative computed tomography. RESULTS: Although overall survival was significantly shorter in the elderly compared to the non-elderly group (p=0.0062), there was no significant difference in disease-specific survival between the two groups (p=0.71) because of the higher rate of death from other diseases. In addition, the elderly group had a significantly higher incidence of osteopenia (p<0.001) and a significantly lower prognostic nutritional index (p<0.001). Multivariate analysis revealed that preoperative osteopenia and a low preoperative prognostic nutritional index were significant risk factors for death from other diseases after gastrectomy in elderly patients. CONCLUSION: In elderly patients with GC, preoperative osteopenia is an important factor to consider in terms of both curability and death from other diseases.

Key Clinical Message: Although partial hepatic necrosis often occurs following endovascular treatment for bleeding associated with hepatic trauma, it is relatively rare that additional treatment is required. However, invasive procedures such as hepatic resection should sometimes be considered when infection occurs over massive hepatic necrosis. Abstract: Although partial hepatic necrosis following endovascular treatment for bleeding associated with hepatic trauma is occasionally experienced, it is relatively rare for the necrotic area of the liver to require additional treatment. However, invasive procedures such as hepatic resection should sometimes be considered when infection occurs over massive hepatic necrosis.
RESUMO
Background: Robotic distal pancreatectomy (RDP) has a better or comparable surgical outcome when compared with laparoscopic distal pancreatectomy (LDP). However, whether the surgical outcome for these procedures in local, low-volume hospitals are comparable with those of the typically larger centers described in published reports remains unclear. Methods: This study enrolled 48 patients who underwent either RDP or LDP between August 2012 and April 2023. Data were retrospectively analyzed to evaluate the short-term surgical outcomes of RDP versus LDP in our hospital, which is a low-volume center. Results: The use of stapling with reinforcement in RDP was significantly higher than in LDP, and the postoperative hospital stay for RDP was significantly shorter than for LDP. Except for these two variables, there were no statistically significant differences between RDP and LDP in preoperative, intraoperative, or postoperative patient characteristics. Conclusion: RDP can be performed as safely and effectively as LDP in a low-volume hospital located in a sparsely populated area.
RESUMO
BACKGROUND/AIM: Preoperative osteopenia, defined as low bone mineral density (BMD), has been reported as a prognostic factor in patients with digestive tract cancers. However, the correlation between preoperative osteopenia and the prognosis of gastric cancer (GC) remains unclear. The aim of this study was to reveal the importance of preoperative osteopenia as a prognostic factor in patients undergoing gastrectomy for GC. PATIENTS AND METHODS: We enrolled 251 patients who had undergone curative surgery for histopathologically diagnosed gastric adenocarcinoma from January 2008 to December 2012. BMD was calculated as the average pixel density (Hounsfield units) within a circle of the mid-vertebral core at the bottom of the 11th thoracic vertebra on preoperative computed tomography. RESULTS: Osteopenia had a high area under the curve and predictive value for both overall survival (OS) and disease-specific survival (DSS). The study cohort was categorized into an osteopenia group and non-osteopenia group based on the optimal BMD cutoff values for OS (157.5) and DSS (195) determined by receiver operating characteristic analysis. The multivariate analysis revealed that OS (hazard ratio=3.607, p<0.001) and DSS (hazard ratio=2.797, p=0.03) were significantly worse in patients with than without preoperative osteopenia. CONCLUSION: Preoperative osteopenia is associated with poor OS and DSS in patients undergoing gastrectomy for GC.

Congenital nephrogenic diabetes insipidus (CNDI) is a rare disease that results in polyuria due to decreased responsiveness to the antidiuretic hormone in the collecting ducts of the kidney. Without compensation by drinking large amounts of water, dehydration and hypernatremia can rapidly develop. We present a case of a patient originally diagnosed with CNDI who required surgery and a fasting period due to adhesive bowel obstruction. The patient was a 46-year-old man who was originally diagnosed with CNDI. He was prescribed trichlormethiazide but self-discontinued treatment in the process. His normal urine output was about 7,000-8,000 mL/day. He underwent robot-assisted radical cystectomy and uretero-cutaneostomy for bladder cancer. Two years later, he was hospitalized due to adhesive bowel obstruction. A 5% glucose solution was infused, and the dose was adjusted according to the urine volume and electrolytes. An adhesiotomy was performed due to recurrent bowel obstruction in a short period of time. A 5% glucose solution was used as the main infusion during the perioperative period. Once drinking water was resumed after surgery, urinary output and electrolytes were easily controlled. In conclusion, patients with CNDI should be given a 5% glucose solution as the primary infusion, and the infusion volume should be adjusted by monitoring daily urine output, electrolytes, and blood glucose levels. Infusion management is easier if oral intake is initiated as early as possible.
RESUMO
Background: We compared short-term clinical outcomes between robotic-assisted minimally invasive esophagectomy (RAMIE) and video-assisted thoracic esophagectomy (VATS-E) using propensity score-matched analysis. Methods: We enrolled 114 patients with esophageal cancer who underwent esophagectomy at our institution from January 2013 to January 2022. Propensity score matching was performed to minimize selection bias between the RAMIE and VATS-E groups. Results: After propensity score matching, 72 patients (RAMIE group, n = 36; VATS-E group, n = 36) were selected for analysis. No significant differences in clinical variables were observed between the two groups. The RAMIE group had a significantly longer thoracic operation time (313 ± 40 vs. 295 ± 35 min, P = 0.048), a higher number of right recurrent laryngeal nerve lymph nodes (4.2 ± 2.7 vs. 2.9 ± 1.9, P = 0.039), and a shorter postoperative hospital stay (23.2 ± 12.8 vs. 30.4 ± 18.6 days, P = 0.018) than the VATS-E group. The RAMIE group tended to have a lower rate of anastomotic leakage (13.9% vs. 30.6%) than the VATS-E group, although the difference was not statistically significant (P = 0.089). No significant differences were found in recurrent laryngeal nerve paralysis (11.1% vs. 13.9%, P = 0.722) or pneumonia (13.9% vs. 13.9%, P = 1.000) between the RAMIE group and the VATS-E group. Conclusion: Although RAMIE for esophageal cancer requires a longer thoracic surgery time, it might be a feasible and safe alternative to VATS-E for treating esophageal cancer. Further analysis is needed to clarify the advantages of RAMIE over VATS-E, especially in terms of long-term surgical outcomes.
RESUMO
PURPOSE: Perioperative surgical stress and systemic inflammation resulting from complex interactions between cancer and the host play an important role in cancer progression. This retrospective study compared the prognostic impact of various perioperative cumulative inflammation- and nutrition-based markers in patients with gastric cancer (GC). METHODS: This study included 301 patients with a histopathological diagnosis of gastric adenocarcinoma who underwent curative surgery. Perioperative cumulative markers were calculated using the newly developed trapezoidal area method. RESULTS: The cumulative prognostic nutritional index (cum-PNI) had the highest area under the receiver operating characteristic (ROC) curve for predicting the overall survival (OS) as well as the relapse-free survival (RFS). The cum-PNI was significantly correlated with tumor-related factors, including tumor size, depth of invasion, lymph node metastasis, lymphatic involvement, vascular involvement, and TNM stage classification. The cum-PNI was also significantly correlated with surgical factors, including surgical approach, gastrectomy, lymphadenectomy, intraoperative blood loss, and postoperative complications. Furthermore, the OS and RFS were poorer in patients with a low cum-PNI (< 236.3) than in those with a high cum-PNI (> 236.3). A multivariate analysis indicated that a low cum-PNI was an independent prognostic indicator in patients with GC. CONCLUSIONS: The cum-PNI might be useful for predicting the prognosis and guiding the perioperative management of patients with GC.

Mediastinal lymph node recurrence is often observed following esophageal cancer surgery; however, no treatment has been established for the same. Surgical resection is often considered for cases of recurrence in a single lymph node region, although the procedures and approaches vary depending on the recurrence site. Right thoracoscopic resection is rarely opted for owing to its high surgical difficulty. Herein, we report a successful case of right thoracoscopic resection in the supine position for recurrent pretracheal lymph nodes following esophagectomy. The intraoperative findings revealed few adhesions around the recurrent lymph nodes due to the initial surgery, and the recurrent lymph nodes were safely resected within a short period. The patient was discharged on postoperative day 4 without any complications, and there was no recurrence after 20 months. Thus, right thoracoscopic resection may be a promising treatment option for recurrent pretracheal lymph nodes after esophagectomy.

Background: Esophagectomy is an invasive and complication-prone surgical procedure. Therefore, a tool that can predict the occurrence of postoperative complications may be useful for perioperative management. In this study, we investigated whether the modified frailty index (mFI) could be a useful tool for predicting the postoperative complications of esophagectomy. Methods: In this study, 162 patients who underwent curative esophagectomy for esophageal squamous cell carcinoma from 2004 to 2019 at our institution were included. The patients were divided into the high mFI (≥ 0.27) and low mFI (< 0.27) groups, and the short-term postoperative outcomes of each group were examined retrospectively. Results: Regarding background factors, age and the American Society of Anesthesiologists physical status classification were significantly higher in the high mFI group (P = 0.049 and P = 0.002, respectively); however, the other items were not significantly different between the two groups. Regarding surgical outcomes, no significant differences in operative time, blood loss, and hospital stay were observed between the two groups. Regarding postoperative complications, pneumonia was significantly more common in the high mFI group (P = 0.035). In multivariate analysis, high mFI (P = 0.034) was an independent predictor of pneumonia, along with operative time ≥ 613 min (P = 0.03) and preoperative BMI < 20.48 (P = 0.006). Conclusion: The mFI is useful for predicting pneumonia after esophagectomy.
RESUMO
PURPOSE: The goal of this study was to determine which markers are the most useful as first- and second-line pre-treatment markers in patients with unresectable or recurrent gastric cancer (URGC). METHODS: This study included 101 URGC patients who were treated with first- and second-line chemotherapy. Several prognostic scores based on nutrition and inflammation were analyzed using a receiver operating characteristic (ROC) analysis to determine the most useful prognostic marker. RESULTS: The lymphocyte-to-C-reactive protein ratio (LCR) had the highest area under the curve for both first- and second-line chemotherapy, according to an ROC analysis. An ROC analysis was used to determine the optimal LCR cut-off for the median survival time before first- and second-line chemotherapy, and patients were divided into high- and low-LCR groups. Patients with a high LCR had a significantly longer survival than those with a low LCR before first- and second-line chemotherapy (p = 0.004, p < 0.001, respectively). A low LCR before both first- and second-line chemotherapy was an independent poor prognostic factor in a multivariate analysis. CONCLUSIONS: URGC patients with a low LCR before both first- and second-line chemotherapy had a significantly worse prognosis than those with a high LCR in this study. Nutritional intervention during chemotherapy induction may lead to a better prognosis.

BACKGROUND: Ferroptosis suppressor protein 1 and glutathione peroxidase 4 have been identified as key molecules in two independent pathways associated with ferroptosis inhibition. This study investigated the prognostic significance and clinical associations of FSP1 and GPX4 expression in esophageal squamous cell carcinoma (ESCC) and assessed the therapeutic potential of regulating these molecules in ESCC cells. METHODS: Immunohistochemical analysis was performed on surgical specimens of 97 patients with ESCC for FSP1 and GPX4 expression. To identify the change in ESCC cell viability, FSP1 and GPX4 inhibitors were administered to three cell lines. In addition, ferroptosis as the cause of reduced cell viability by FSP1 and GPX4 inhibition was confirmed. RESULTS: Prognosis was significantly worse for patients in the group positive for both FSP1 and GPX4 compared with the other groups (p < 0.001). In multivariate analysis, positivity for both FSP1 and GPX4 was an independent poor prognostic factor (p = 0.002). The combination of FSP1 and GPX4 inhibitors induced cell death more potently than each inhibitor did alone. Furthermore, the ferroptosis inhibitor markedly canceled this cell death. CONCLUSIONS: Overexpression of FSP1 and GPX4 is a poor prognostic factor for patients with ESCC. Simultaneous suppression of both FSP1 and GPX4 caused potent cell death, which was markedly abrogated by ferroptosis inhibitors. These findings indicate that simultaneous regulation of FSP1 and GPX4 may be a new therapeutic target in ESCC.
