RESUMEN
INTRODUCTION: Obesity impairs patients' quality of life (QoL). Laparoscopic sleeve gastrectomy (LSG) is a common procedure for patients with severe obesity; however, studies reporting changes in obesity-related QoL are limited. The aim of this study was to assess changes in obesity-related QoL and food tolerance in the early postoperative period. METHODS: We included 20 consecutive patients who underwent LSG between May 2021 and July 2023. We evaluated changes in obesity-related QoL 6 months after surgery using an obesity and weight loss QoL questionnaire (OWLQOL) and a weight related symptom measure (WRSM). Additionally, we assessed eating satisfaction and food tolerance after surgery. RESULTS: The percentages of total weight loss and excess weight loss were 28.5% and 79.1%, respectively. OWLQOL scores and WRSM changed from 36.5 to 73.0 points and from 44.0 to 15.0 points (p = .007, .007), respectively. The food tolerance score decreased from 25 to 21.2 points (p < .001), while eating satisfaction showed no significant change (p = .25). CONCLUSION: Obesity-related QoL is enhanced even in the early postoperative period, without sacrificing eating satisfaction. The findings of this study may provide valuable insights for patients when considering LSG.

PURPOSE: To compare the pathophysiology and surgical outcomes of emergency surgery for upper gastrointestinal tract perforation with and without fungal peritonitis and identify the risk factors for fungal peritonitis. METHODS: The subjects of this retrospective study were patients with upper gastrointestinal perforation and peritonitis who underwent emergency surgery at a single medical center in Japan. The patients were allocated to two groups according to the presence or absence of fungal peritonitis: group F and group N, respectively. RESULTS: At the time of surgery, ascitic fluid culture or serum ß-D glucan levels were available for 54 patients: 29 from group F and 25 from group N, respectively. The stomach was perforated in 14 patients (25.9%) and the duodenum was perforated in 40 patients (74.1%). Group F had a higher proportion of patients with low preoperative prognostic nutritional index scores (≤ 40) and C-reactive protein levels and a higher postoperative complication rate. The time to initiate food intake and the postoperative hospital stay were also significantly longer in group F. Multivariate analysis identified that the perforation site of the stomach was a risk factor for fungal peritonitis. CONCLUSION: Patients with fungal peritonitis from upper gastrointestinal tract perforation had higher postoperative complication rates, delayed postoperative recovery, and a longer hospital stay. Gastric perforation was a risk factor for fungal peritonitis.
RESUMEN
BACKGROUND/AIM: The purpose of this study was to evaluate the outcomes of the sentinel node navigation surgery (SNNS) followed by limited gastrectomy for early gastric cancer (EGC) with Endoscopic Curability C-2 (eCuraC-2). PATIENTS AND METHODS: Between 2001 and 2018, 33 patients were included in this study. Following sentinel node (SN) biopsy using indocyanine green combined with an infrared ray laparoscopic system, limited gastrectomy (LG) [wedge resection (WR), or segmental gastrectomy (SG)] was performed without extended lymphadenectomy. RESULTS: SN detection rate was 97% (32/33). The mean number of SNs per case was 7.8. Three patients (9.1%) with lymph node metastasis (LNM) had a positive SN identified by intraoperative pathological examination. When intraoperative pathologic examination showed SN to be LNM negative, 11 patients underwent WR, and seven were subjected to SG. Postoperative pathological examinations showed no false negatives for LNM, and four patients (12%) had residual cancer in their resected stomachs. Overall survival and disease-specific survival five years after SNNS were 87.9% and 100%, respectively. CONCLUSION: SNNS followed by LG with lymphatic basin resection may be one of the ideal procedures for patients with eCuraC-2 due to the accurate diagnosis of LNM and favorable disease-specific prognosis.

PURPOSE: Sarcopenia is a prognostic predictor in emergency surgery. However, there are no reports on the relationship between osteopenia and in-hospital mortality. This study clarified the effect of preoperative osteosarcopenia on patients with gastrointestinal perforation after emergency surgery. METHODS: We included 216 patients with gastrointestinal perforations who underwent emergency surgery between January 2013 and December 2022. Osteopenia was evaluated by measuring the pixel density in the mid-vertebral core of the 11th thoracic vertebra. Sarcopenia was evaluated by measuring the area of the psoas muscle at the level of the third lumbar vertebra. Osteosarcopenia is defined as the combination of osteopenia and sarcopenia. RESULTS: Osteosarcomas were identified in 42 patients. Among patients with osteosarcopenia, older and female patients and those with an American Society of Anesthesiologists Physical Status of ≥ 3 were significantly more common, and the body mass index, hemoglobin value, and albumin level were significantly lower in these patients than in patients without osteosarcopenia. Furthermore, the osteosarcopenia group presented with more postoperative complications than patients without osteosarcopenia (P < 0.01). In the multivariate analysis, age ≥ 74 years old (P = 0.04) and osteosarcopenia (P = 0.04) were independent and significant predictors of in-hospital mortality. CONCLUSION: Preoperative osteosarcopenia is a risk factor of in-hospital mortality in patients with gastrointestinal perforation after emergency surgery.

BACKGROUND: The real-world efficacy, feasibility, and prognostic factors of immune-checkpoint inhibitor combination therapy for unresectable or metastatic esophageal cancer are not fully established. METHODS: This multi-institutional retrospective cohort study evaluated 71 consecutive patients treated with immune-checkpoint inhibitor combination therapy for esophageal cancer between March 2021 and December 2022. We assessed tumor response, safety, and long-term survival. RESULTS: In patients with measurable lesions, the response rate was 58%, and the disease control rate for all enrolled patients was 80%. Five patients (7.0%) underwent successful conversion surgery. Grade 3 or higher immune-related adverse events occurred in 13% of patients, and one patient (1.4%) died due to cholangitis. Median progression-free survival was 9.7 (95% confidence interval: 6.5-not reached). C-reactive protein levels and performance status were identified as significant predictors of progression-free survival through Cox proportional hazards analysis. CONCLUSIONS: Immune-checkpoint inhibitor combination therapy for esophageal cancer demonstrated comparable tumor response, safety, and long-term survival to previous randomized clinical trials. Patients with good performance status and low C-reactive protein levels may be suitable candidates for this treatment.

PURPOSE: Systemic inflammatory response markers are reported to be prognostic for patients with cancer. The C-reactive protein (CRP)-albumin-lymphocyte (CALLY) index has been established as an immuno-nutritional scoring system. The aim of this study was to clarify the impact of the preoperative CALLY index on the outcome of patients undergoing gastrectomy for gastric cancer. METHODS: We analyzed the data of 826 patients who underwent gastrectomy for stage I, II, or III gastric cancer between 2010 and 2017. The CALLY index was defined as (albumin × lymphocyte)/(CRP × 104). RESULTS: The cut-off of the CALLY index was 2. The 147 patients with a preoperative CALLY index < 2 had significantly worse overall survival (OS) and relapse-free survival (RFS) than those with a CALLY index ≥ 2 (P < 0.01, P < 0.01, respectively). Multivariate analysis identified that a CALLY index < 2 (P = 0.02), intraoperative blood loss (P < 0.01), and stage II or III disease (P < 0.01) were independent and significant predictors of worse RFS. A CALLY index < 2 (P = 0.01), intraoperative blood loss (P < 0.01), postoperative complications (P = 0.02), and stage II or III disease (P < 0.01) were independent and significant predictors of worse OS. CONCLUSION: The preoperative CALLY index was independently associated with a poor prognosis for patients after gastrectomy for gastric cancer.

BACKGROUND: Systemic inflammatory response is significant prognostic indicator in patients with various diseases. The relationship between prognostic scoring systems based on the modified Glasgow Prognostic Score (mGPS) and achalasia in patients treated with laparoscopic Hellermyotomy with Dorfundoplication (LHD) remains uninvestigated. This study aimed to examine the role of mGPS in patients with achalasia. METHODS: 457 patients with achalasia who underwent LHD as the primary surgery between September 2005 and December 2020 were included. We divided patients into the mGPS 0 and mGPS 1 or 2 groups and compared the patients' background, pathophysiology, symptoms, surgical outcomes, and postoperative course. RESULTS: mGPS was 0 in 379 patients and 1 or 2 in 78 patients. Preoperative vomiting and pneumonia were more common in patients with mGPS of 1 or 2. There were no differences in surgical outcomes. Postoperative upper gastrointestinal endoscopy revealed that severe esophagitis was more frequently observed in patients with mGPS of 1 or 2 (P < 0.01). The clinical success was 91% and 99% in the mGPS 0 and mGPS 1 or 2 groups, respectively (P < 0.01). CONCLUSIONS: Although severe reflux esophagitis was more common in patients with achalasia with a high mGPS, good clinical success was obtained regardless of the preoperative mGPS.

Laparoscopic sleeve gastrectomy (LSG) is the most frequently performed procedure in bariatric-metabolic surgery (BMS) worldwide, accounting for approximately 90% of BMS procedures in Japan. While numerous studies have reported on the safety and efficacy of LSG, gastroesophageal reflux disease (GERD) remains a major postoperative complication. Although Roux-en-Y gastric bypass (RYGB) is preferred for severe obesity with GERD, it is less suitable for Japanese patients who have a higher risk of gastric cancer due to the remnant stomach which is difficult to observe with esophago-gastro-duodenoscopy. To address de novo and exacerbation GERD after LSG, we conducted LSG with Toupet fundoplication (T-sleeve) for Japanese patients with severe obesity. In our first T-sleeve case, the patient demonstrated sufficient weight loss and improved GERD following surgery. Hence, we suggest that T-sleeve is a feasible option for Japanese patients with obesity and concurrent GERD.

BACKGROUND/AIM: The Japan Society of Endoscopic Surgery (JSES) proctoring system was established to prevent serious pancreatic pressure injuries in Japan in 2019. To safely perform robotic gastrectomy (RG) in our hospital, which has no experience in robotic surgery, we conducted a clinical trial with the support of this proctoring system. PATIENTS AND METHODS: The present study was a single-center clinical prospective study. The primary endpoint was morbidity determined using Clavien-Dindo classification (C-D) Grade IIIa or higher. RESULTS: Ten patients, seven males and three females, were recruited in this study. RG was performed under the proctoring system of the JSES in the initial six cases and was completed independently for the remaining four patients. We successfully performed the initial ten cases without C-D classification grade IIIa or higher morbidities. CONCLUSION: This study underscores the significance of a proctoring system for introducing RG to facilities with limited experience in robotic surgery. Despite some limitations, this study demonstrated successful outcomes in the initial ten cases, emphasizing the benefits for both surgeons and patients. This study provides valuable insights into the safety of RG in small institutions and calls for further research in this area.

OBJECTIVE: Anastomotic leakage is one of the most severe complications after esophagectomy. However, a diagnostic gold standard for anastomotic leakage has not been established yet. This retrospective cohort study aimed to evaluate the potential use of routine postoperative contrast-enhanced computed tomography findings as an early predictor of anastomotic leakage in patients who underwent esophagectomy for esophageal cancer. METHODS: This study included 75 patients who underwent Mckeown esophagectomy, of whom 22 developed anastomotic leakage after surgery. The computed tomography findings for this patient cohort were categorized into 3 grades based on mural enhancement patterns observed at the anastomotic site. Both semiquantitative and quantitative analyses were performed, and the interobserver agreement between the 2 experienced radiologists was assessed. RESULTS: It was found that poor enhancement in both the early and portal venous phases (grade 2) had a robust association with the occurrence of anastomotic leakage. The computed tomography enhancement ratio that is used to estimate wall degeneration and ischemia was significantly higher in patients with anastomotic leakage. CONCLUSIONS: Routine postoperative contrast-enhanced computed tomography could be beneficial for the early detection of anastomotic leakage, even in asymptomatic patients, after esophagectomy.
RESUMEN
BACKGROUND: While laparoscopic fundoplication is a standard surgical procedure for patients with esophageal hiatal hernias, the postoperative recurrence of esophageal hiatal hernias is a problem for patients with giant hernias, elderly patients, or obese patients. Although there are some reports indicating that reinforcement with mesh is effective, there are differing opinions regarding the use thereof. The aim of this study is to investigate whether mesh reinforcement is effective for laparoscopic fundoplication in patients with esophageal hiatus hernias. METHODS: The subjects included 280 patients who underwent laparoscopic fundoplication as the initial surgery for giant esophageal hiatal hernias, elderly patients aged 75 years or older, and obese patients with a BMI of 28 or higher, who were considered at risk of recurrent hiatal hernias based on the previous reports. Of the subject patients, 91 cases without mesh and 86 cases following the stabilization of mesh use were extracted to compare the postoperative course including the pathology, symptom scores, surgical outcome, and recurrence of esophageal hiatus hernias. RESULTS: The preoperative conditions indicated that the degree of esophageal hiatal hernias was high in the mesh group (p = 0.0001), while the preoperative symptoms indicated that the score of heartburn was high in the non-mesh group (p = 0.0287). Although the surgical results indicated that the mesh group underwent a longer operation time (p < 0.0001) and a higher frequency of intraoperative complications (p = 0.037), the rate of recurrence of esophageal hiatal hernia was significantly low (p = 0.049), with the rate of postoperative reflux esophagitis also tending to be low (p = 0.083). CONCLUSIONS: Mesh reinforcement in laparoscopic fundoplication for esophageal hiatal hernias contributes to preventing the recurrence of esophageal hiatal hernias when it comes to patient options based on these criteria.

BACKGROUND: Although findings from both animal and clinical research indicate that the blood-brain barrier (BBB) contributes to the pathogenesis of various psychiatric disorders (including depression), the underlying mechanisms are unknown. We investigated the levels of the tight-junction proteins claudin-5 and aquaporin-4 (AQP-4) in astrocytes of learned helplessness (LH) rats (an animal model of depression) and non-LH rats (a model of resilience). METHODS: We administered inescapable mild electric shock to rats and then identified the LH and non-LH rats by a post-shock test. The expressions of claudin-5 and AQP-4 in several brain regions of the LH and non-LH rats were then evaluated by a western blot analysis. RESULTS: The levels of both claudin-5 and AQP-4 in the CA-1 and CA-3 hippocampal areas of the LH group were significantly lower than those of the control group, whereas those of the non-LH rats were not significantly different from those of the control and LH rats. CONCLUSIONS: These results suggest that LH rats but not non-LH rats experienced down-regulations of claudin-5 and AQP-4 in the CA-1 and CA-3. It is possible that a region-specific modulation of claudin-5 and AQP-4 is involved in the mechanisms of vulnerability but not resilience in depression.

BACKGROUND: Accumulating evidence suggests that expression levels of tumor-infiltrating (TI) cells may play a prognostic role in patients with esophageal cancer who have undergone esophagectomy. However, its effect on patients undergoing neoadjuvant docetaxel, cisplatin, and 5-fluorouracil (DCF) therapy followed by esophagectomy for esophageal squamous cell carcinoma (ESCC) remains unclear. Therefore, this study aimed to elucidate the prognostic impact of TI cells in patients who underwent esophagectomy following neoadjuvant DCF therapy. METHODS: Overall, 81 patients with ESCC who underwent curative esophagectomy following neoadjuvant DCF therapy were included. The number of TI CD8+ cells was determined using light microscopy at ×400 in tumor invasive margins. Receiver operative characteristic curve was used to determine the cutoff values for mortality for continuous variables; the patients were separated into high and low TI CD8+ cell groups and their backgrounds and clinical outcomes were compared. RESULTS: Overall and relapse-free survival were significantly worse in the TI CD8+-low group than that in the TI CD8+-high group (p < 0.01). Multivariate analysis revealed that positive ypN (hazard ratio [HR], 3.12; 95% confidence interval [CI], 1.08-9.02) and low TI CD8+ cell levels (HR, 2.77; 95% CI, 1.31-5.85) were independent prognostic factors for overall survival. Furthermore, positive venous invasion (HR, 2.63; 95% CI, 1.29-5.35) and low TI CD8+ cell levels (HR, 2.77; 95% CI, 1.70-5.46) were significant prognostic factors for relapse-free survival. CONCLUSIONS: Low TI CD8+ cell level was a prominent prognostic factor for patients with ESCC undergoing neoadjuvant DCF therapy followed by esophagectomy.

PURPOSE: Some prospective trials have demonstrated the feasibility of sentinel node (SN) biopsy in gastric cancer (GC) surgery. This study aimed to identify the appropriate concentration settings for the intraoperative injection of indocyanine green (ICG) for SN biopsy. METHODS: Before the clinical studies, porcine model experiments explored the optimal concentration of ICG injected intraoperatively. Next, nine GC patients were enrolled in the clinical research. ICG (0.5 ml) was injected intraoperatively into four quadrants of the submucosa around the tumor at various concentrations (0.5, 0.25, and 0.1 mg/ml). The lymphatic basin dissection method was applied to the ICG-positive lymphatic areas. The number and location of the lymphatic basins and positive nodes were recorded intraoperatively. RESULTS: In the porcine model, the visibility gradually became clear at an ICG concentration higher than 0.1 mg/ml. In the clinical study, the average number of detected lymphatic basins was 3.3, 1.7, and 1.7, respectively. The mean number of detected SNs was 14.7, 6.7, and 4.0, respectively. CONCLUSION: To improve the reproducibility of SN biopsy, it is essential to prepare the correct concentration setting of ICG. Under current conditions in which ICG is injected intraoperatively, a 0.1 mg/ml concentration setting of ICG may be necessary and sufficient for SN identification.

Background: Risk prediction of anastomotic leakage using anatomical and vascular factors has not been well established. This study aimed to assess the anatomical and vascular factors affecting the hemodynamics of the gastric conduit and develop a novel risk stratification system in patients undergoing esophagectomy with retrosternal reconstruction. Methods: This retrospective cohort study analyzed 202 patients with esophageal cancer who underwent subtotal esophagectomy with gastric tube retrosternal reconstruction between January 2008 and December 2020. Risk factors for anastomotic leakage (AL), including the anatomical index (AI) and anastomotic viability index (AVI), were evaluated using a logistic regression model. Results: According to the logistic regression model, the independent risk factors for AL were preoperative body mass index ≥23.6 kg/m2 (odds ratio [OR], 7.97; 95% confidence interval [CI], 2.44-26.00; P < 0.01), AI <1.4 (OR, 23.90; 95% CI, 5.02-114.00; P < 0.01), and AVI <0.62 (OR, 8.02; 95% CI, 2.57-25.00; P < 0.01). The patients were stratified into four AL risk groups using AI and AVI as follows: low-risk group (AI ≥1.4, AVI ≥0.62 [2/99, 2.0%]), intermediate low-risk group (AI ≥1.4, AVI <0.62 [2/29, 6.9%]), intermediate high-risk group (AI <1.4, AVI ≥0.62 [8/53, 15.1%]), and high-risk group (AI <1.4, AVI <0.62 [11/21, 52.4%]). Conclusion: The combination of AI and AVI strongly predicted AL. Additionally, the use of AI and AVI enabled the stratification of the risk of AL in patients who underwent esophagectomy with retrosternal reconstruction.
RESUMEN
BACKGROUND: Trastuzumab-based chemotherapy is a standard treatment regimen for human epithelial growth factor 2 (HER2)-positive gastric cancer. This is a case of a patient who has survived 12 years after being diagnosed with advanced gastric cancer with multiple liver and lung metastases. CASE PRESENTATION: A woman in her 70s underwent total gastrectomy, cholecystectomy, and left hepatic lobectomy for gastric cancer with liver metastasis. One month after the surgery, multiple liver metastases appeared. After two courses of S-1 + CDDP chemotherapy, the liver metastases disappeared, and new lung metastases occurred. Because the primary tumor was HER2 positive, S-1 + CDDP + trastuzumab chemotherapy was performed. After one course of chemotherapy, the blood test showed pancytopenia, and CDDP was discontinued. S-1 + trastuzumab chemotherapy was then initiated, and as a result, the lung metastases disappeared. The patient is alive without recurrence 12 years after the surgery. CONCLUSIONS: We encountered a case of long-term survival after multidisciplinary treatments for HER2-positive advanced gastric cancer with multiple liver and lung metastases.
RESUMEN
Colorectal metastasis from gastric cancer is rare and may develop several years after gastric cancer surgery. Therefore, colonoscopic findings provide useful diagnostic information. The present report describes a case of gastric cancer colon metastasis diagnosed 8 years and 10 months after gastrectomy for advanced gastric cancer. A 64-year-old male patient underwent gastrectomy in December 2010 and received chemotherapy for 4 years and 10 months after the surgery. Subsequently, the patient was diagnosed as having colorectal cancer by computed tomography in February 2019. Colonoscopy revealed linitis plastica-like colon stenosis; however, biopsy pathology did not reveal any findings indicating malignancy. Right hemicolectomy was performed, and pathological examination revealed colon metastasis from gastric cancer. The patient received chemotherapy but died of peritoneal carcinomatosis 1 year and 8 months after the colectomy. According to literature, colorectal metastasis from gastric cancer is often attributed to hematogenous metastasis and often exhibits characteristic macroscopic features. Treatments, such as chemotherapy for gastric cancer and/or colorectal resection, are considered effective for gastric cancer colorectal metastasis.
RESUMEN
BACKGROUND: Preoperative C-reactive protein-to-albumin ratio (CAR) and neutrophil-to-lymphocyte ratio (NLR) are correlated with a poor prognosis of various cancers. The significance of postoperative systemic inflammation markers for prognostic stratification of patients with esophageal cancer (EC) has not been established. Therefore, this study aimed to elucidate the impact of postoperative CAR and NLR on survival in patients with EC for prognostic stratification. METHODS: A total of 235 patients who received curative esophagectomy were analyzed. A Cox proportional hazard model was performed to detect prognostic factors. RESULTS: Multivariate analysis revealed that postoperative CAR ≥ 0.05 (hazard ratio [HR], 1.62; 95% confidence interval [CI], 1.01-2.57) and NLR ≥ 3.0 (HR, 2.81; 95% CI, 1.79-4.40) were independent prognostic factors for overall survival. Meanwhile, postoperative CAR ≥ 0.05 (HR, 1.61; 95% CI, 1.07-2.41) and NLR ≥ 3.0 (HR, 1.92; 95% CI, 1.29-2.85) were also significant prognostic factors for relapse-free survival. In addition, the patient group with postoperative CAR ≥ 0.05 and NLR ≥ 3.0 had the worst survival. CONCLUSIONS: Postoperative CAR ≥ 0.05 and NLR ≥ 3.0 can predict the poor survival of patients who received curative esophagectomy for EC.
