RESUMO
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: 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.

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.

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.
RESUMO
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.

BACKGROUND: Neoadjuvant chemotherapy followed by surgery is Japan's most effective treatment modality for advanced thoracic esophageal squamous cell carcinoma. However, the prognosis is not as expected. This study aimed to examine prognostic factors in patients with pathologically ineffective neoadjuvant chemotherapy followed by surgery for esophageal squamous cell carcinoma. METHODS: We retrospectively analyzed patients who underwent neoadjuvant chemotherapy followed by curative esophagectomy for esophageal squamous cell carcinoma between December 2008 and July 2021. The patients were divided into the neoadjuvant chemotherapy effective group and the neoadjuvant chemotherapy ineffective group according to the pathological diagnosis. Clinicopathological data, prognosis, and recurrence were analyzed. RESULTS: A total of 143 patients (121 males, 22 females; median age, 67 years) were included in this study. Of these, 34 patients were classified into the effective group and the remaining 109 patients were assigned to the ineffective group. The ineffective group had significantly worse overall survival and recurrence-free survival than the effective group (p = 0.0192 and p = 0.0070, respectively). In the ineffective group, multivariate analysis demonstrated that microscopic venous invasion was an independent prognostic factor for overall survival (hazard ratio 2.44; 95% confidence interval 1.13-5.30) and recurrence-free survival (hazard ratio 2.43; 95% confidence interval 1.24-4.73). CONCLUSIONS: Microscopic venous invasion was associated with poor survival and cancer recurrence in the neoadjuvant chemotherapy ineffective group of patients who underwent esophagectomy for esophageal squamous cell carcinoma.

BACKGROUNDS: The optimal method for evaluating frailty grade in patients with cancer has not been established in patients undergoing esophagectomy for esophageal cancer. This study aimed to clarify the impact of cachexia index (CXI) and osteopenia on survival in esophagectomized patients for esophageal cancer to develop frailty grade for risk stratification of the prognosis. METHODS: A total of 239 patients who underwent esophagectomy were analyzed. CXI was calculated as follows: skeletal muscle index × serum albumin/neutrophil-to-lymphocyte ratio. Meanwhile, osteopenia was defined as below the cutoff value of bone mineral density (BMD) calculated by the receiver operating characteristic curve. We evaluated the average Hounsfield unit within a circle in the lower midvertebral core of the 11th thoracic vertebra on preoperative computed tomography as BMD. RESULTS: Multivariate analysis revealed that low CXI (Hazard ratio [HR], 1.95; 95% confidence interval [CI], 1.25-3.04) and osteopenia (HR, 1.86; 95% CI, 1.19-2.93) were independent prognostic factors for overall survival. Meanwhile, low CXI (HR, 1.58; 95% CI, 1.06-2.34) and osteopenia (HR, 1.57; 95% CI, 1.05-2.36) were also significant prognostic factors for relapse-free survival. A frailty grade combined with CXI and osteopenia stratified into four groups by their prognosis. CONCLUSIONS: Low CXI and osteopenia predict poor survival in patients undergoing esophagectomy for esophageal cancer. Furthermore, a novel frailty grade combined with CXI and osteopenia stratified the patients into four groups according to their prognosis.

BACKGROUND: Impaired gastric conduit perfusion during esophagectomy and reconstruction is considered a key risk factor of anastomotic leaks. The aim of this study is to evaluate the indication and feasibility of additional microvascular anastomosis (AMA) to the gastric conduit in esophageal cancer surgery. PATIENTS AND METHODS: Patients who received an esophagectomy with gastric conduit reconstruction between July 2008 and July 2021 at a single center were reviewed. Patient characteristics, anastomotic viability index (AVI) of the gastric conduit measured with thermal imaging, and operative outcomes were analyzed using Fisher's exact test and Mann-Whitney U test. Two propensity score weighting methods (inverse probability of treatment weighting and overlap weighting) were applied to investigate whether AMA reduces anastomotic leaks. RESULTS: Of the 293 patients who underwent an esophagectomy over the study period, 26 received AMA. AVI in the AMA group was significantly lower than that in the control group (0.64 vs. 0.74, p = 0.026). Overall anastomotic leak rates were 3.8% in the AMA group and 12.4% in the control group. Using two different propensity score weighting methods, the same conclusion was obtained that AMA significantly reduced anastomotic leaks after esophagectomy (both p < 0.001). The logistic regression model for estimating probability of anastomotic leaks provided AVI criteria for AMA application and revealed that AMA significantly reduced the estimated leak rates by a maximum of 49%. CONCLUSIONS: Additional microvascular anastomosis significantly reduced anastomotic leaks after esophagectomy. The proposed AVI criteria for AMA application can help guide surgeons as to when AMA is needed.

Background: The aim of the trial is to evaluate the effectiveness of interventions provided by online support program apps, adopting health-related quality of life (HR-QOL) scores as indicators. Methods: The design is as an open, randomized, parallel-group trial with longitudinal data collection. The subjects will be female cancer patients receiving treatment in a Japanese National Cancer Hospital. Patients assigned to the experimental group will use three apps: an app for them to monitor their own health (monitoring app), an app to assess their understanding of their diagnosis and treatment and their readiness to receive treatment (confirmation app), and an app to address mental health issues (writing app); patients assigned to the control group will use only the monitoring app. At baseline (before patients undergo cancer treatment) and three other times during the study, evaluation indicators will be obtained from three different standardized HR-QOL scales that are incorporated in the monitoring app. The study hypothesis is that at 6 months after patients' baseline health monitoring, patients in the experimental group will have improved HR-QOL as compared with patients in the control group. Conclusion: This study is based on self-regulation theory, so it is important that the online support program works in an efficient way with respect to patients finding and setting their own health-related goals and adapting their behaviors to achieve those goals. Verifying the effectiveness of the combination of the three apps will show that it is a scientifically valid approach to maintaining or improving the HR-QOL of cancer patients.
RESUMO
BACKGROUND/AIM: Despite recent progress in surgical techniques and perioperative management, postesophagectomy pneumonia remains the most common complication. Thus, it is important to identify the risk factors of postoperative pneumonia and to improve perioperative management. This study aimed to clarify risk factors for postoperative pneumonia and subsequently stratify the risk of pneumonia. PATIENTS AND METHODS: A total of 154 patients who underwent subtotal esophagectomy were divided into two groups: patients without pneumonia and those with pneumonia. Their backgrounds and operative outcomes were compared. Furthermore, risk factors of postoperative pneumonia were evaluated using a logistic regression model. RESULTS: Postoperative pneumonia developed in 18.8% (n=29) of the study cohort. In the multivariate analysis, the independent risk factors for postoperative pneumonia were forced expiratory volume at 1 s (FEV1) <1.98 l [p=0.011; odds ratio (OR)=3.960; 95% confidence interval (CI)=1.380-11.400], thoracotomy (p=0.043; OR=3.110; 95%CI=1.030-9.320), operative blood loss ≥390 ml (p=0.013; OR=3.900; 95%CI=1.340-11.400), and recurrent laryngeal nerve palsy (RLNP) (p=0.014; OR=3.740; 95%CI=1.310-10.700). Patients were also stratified into the following four groups as per the number of significant risk factors: the incidence of pneumonia in patients with no risk factor, one risk factor, two risk factors, three risk factors were 7.0% (5/71), 13.7% (7/51), 43.5% (10/23), and 77.7% (7/9), respectively. CONCLUSION: FEV1 <1.98 l, thoracotomy, operative blood loss ≥390 ml, and RLNP were independent risk factors of postoperative pneumonia. Additionally, patients could be stratified into four groups according to the incidence of pneumonia.

Anastomotic stricture (AS) is one of the major complications after esophagectomy for esophageal cancer. We have previously reported that severe mucosal degeneration (MD) of the anastomotic site was associated with the incidence of AS. Meanwhile, there are few reports to correlate anastomotic internal circumference (AIC) with computed tomography (CT) with the incidence of AS. Therefore, this study was conducted to clarify the correlation of early postoperative endoscopic and CT findings with the incidence of AS. We assessed 205 patients who underwent esophagectomy. We then divided them into the non-AS group (n = 164) and the AS group (n = 41) and compared their background data and intraoperative and postoperative outcomes. We also evaluated the risk factors for AS using logistic regression model. Multivariate analysis revealed small AIC (P = 0.003; OR = 4.400; 95% CI = 1.650-11.700) and severe MD (P < 0.001; OR = 7.200; 95% CI = 2.650-19.600) as the independent risk factors for AS development. We also stratified the patients into the following four groups according to the incidence of AS: low-risk (normal AIC and intact or mild MD, 6.2%), intermediate-risk (small AIC and intact or mild MD, 29.4%), high-risk (normal AIC and severe MD, 42.9%), and very high-risk (small AIC and severe MD, 61.1%). Early postoperative endoscopic and CT findings were useful in predicting the development of AS after esophagectomy.

INTRODUCTION: Recent studies showed that intraoperative indocyanine green (ICG) fluorescence imaging-guided surgery helped evaluate organ perfusion. Whereas whether the gastric remnant can be preserved after distal gastrectomy for the cases of post-Nissen fundoplication remains unclarified. This case report demonstrated the applicability of intraoperative ICG fluorescence-guided surgery to assess the gastric remnant's blood supply after distal gastrectomy. CASE PRESENTATION: A 68-year-old man who previously underwent Nissen fundoplication for esophageal hiatal hernia was diagnosed with early gastric cancer in the lower body of the stomach. We performed laparoscopic distal gastrectomy to preserve the left gastroepiploic vessels considering the dissection of a part of the short gastric vessel from the previous Nissen fundoplication. After completing Billroth I reconstruction, the color of the serosal surface did not show any signs of ischemia. However, intraoperative esophagogastroduodenoscopy showed an ischemic change of the remnant stomach. In addition, ICG fluorography revealed insufficient blood supply to the gastric remnant compared with that to the pancreas and liver. Consequently, we converted to total gastrectomy to avoid necrosis in the gastric remnant. CONCLUSION: We performed intraoperative ICG fluorescence-guided surgery in patients with early gastric cancer after Nissen fundoplication. ICG fluorescence may be useful in preventing postoperative gastric remnant ischemia, especially in high-risk patients.
RESUMO
BACKGROUND: The advantages of prone position in minimally invasive esophagectomy have not been well studied. This study aimed to investigate the safety and feasibility of a transition from the left lateral decubitus position to the prone position for thoracic procedures in minimally invasive esophagectomy. METHODS: We retrospectively analyzed patients with thoracic esophageal carcinomas who underwent thoracoscopic esophagectomy and laparoscopic gastric mobilization between January 2015 and December 2019. The left decubitus and prone positions were analyzed using propensity score-matched pairs for the baseline characteristics, morbidity, and survival. RESULTS: A total of 114 consecutive patients were included in this study; 90 (78.9%) were male and the median age was 67.2 years old. Of these patients, 39 and 75 underwent left decubitus and prone esophagectomy, respectively. Prone esophagectomy was associated with a lower incidence of pneumonia than that performed in the decubitus position (12.5% vs. 37.5%, p = 0.0187). With respect to the long-term outcomes, there were no significant differences between the 2 groups. The 4-year overall and relapse-free survival rates for prone and decubitus esophagectomy were 73.8% and 73.2%, and 84.4% and 71.8%, respectively (p = 0.9899 and 0.6751, respectively). Prone esophagectomy yielded a shorter operative time (total: 528 [485-579] min vs. 581 [555-610] min, p < 0.0022; thoracic section: 243 [229-271] min vs. 292 [274-309] min, p < 0.0001), less bleeding in the thoracic procedures (0 [0-10] mL vs. 70 [20-138] mL, p < 0.0001), a shorter length of postoperative hospital stay (19 [15-23] vs. 30 [21-46] days, p = 0.0002), and a lower total hospital charge (30,046 [28,175-32,660] US dollars vs. 36,396 [31,533-41,180] US dollars, p < 0.0001). CONCLUSIONS: Transition into the prone position in minimally invasive esophagectomy is feasible with adequate postoperative and oncological safety and economical in esophageal cancer surgery.

BACKGROUND: Despite the risk of recurrent laryngeal nerve (RLN) palsy during esophagectomy, no established method of monitoring RLN injury is currently available. METHODS: This study included 187 patients who underwent esophagectomy between 2011 and 2018. Among these, intraoperative nerve monitoring (IONM) was done in 142 patients (IONM group), while the remaining 45 patients underwent conventional surgery without IONM (control group). We investigated the incidence of postoperative complications with regard to the use of IONM. RESULTS: The overall incidence of postoperative RLN palsy was 28% (52/187). The IONM group showed a significantly lower incidence of postoperative RLN palsy as compared to that in the control group (p = 0.004). The overall incidence of postoperative pneumonia was 22% (41/187) in those with Clavien-Dindo (CD) classification beyond grade 2. There were no significant differences between the incidence of any grade of postoperative pneumonia and the use of IONM (p = 0.195 and 0.333; CD > 2 and > 3, respectively). Multivariate analysis demonstrated that tumors in the upper third [odds ratio (OR) 3.12; 95% confidence interval (CI) 1.04-9.29] and lack of IONM use (OR 2.51; 95% CI 1.17-5.38) were independent factors causing postoperative RLN palsy after esophagectomy. CONCLUSION: IONM helps to reduce the risk of postoperative RLN palsy after esophageal cancer surgery.

BACKGROUND: Many surgeons preferably place a trans-nasal feeding tube or a feeding enterostomy for post-operative nutritional management after esophagectomy. Various types of tubes (such as nasogastric, transgastric, transduodenal, or transjejunal tubes) have been used for enteral feeding; however, the appropriate enteral feeding routes have not yet been proposed. Therefore, this study aimed to evaluate the feasibility and safety of button-type jejunostomy. METHODS: We reviewed 201 patients who underwent esophagectomy with placement of a button-type jejunostomy at the Jikei University Hospital (Tokyo, Japan) between 2008 and 2019. The analyzed variables included clinicopathological characteristics, operative data, jejunostomy-related characteristics, and postoperative complications. Postoperative bodyweight loss was examined 6 months and 1 year after the operation. RESULTS: Refractory enterocutaneous fistula and bowel obstruction occurred in 13 (6.5%) and 14 (7.0%) patients, respectively. The body mass index at button-type jejunostomy removal was significantly lower and the duration of button-type jejunostomy placement was significantly longer in patients with a refractory enterocutaneous fistula (p = 0.023 and p < 0.001, respectively). Bowel obstruction was significantly more likely to develop in patients with a non-squamous cell carcinoma (p = 0.021) and in patients who underwent open abdominal procedures (p < 0.001). After 1 year, the median bodyweight losses were 12.1% and 15.6% in patients with short and long jejunostomy placement durations (p = 0.642), respectively. CONCLUSION: A button-type jejunostomy is durable and allows easy self-management for maintaining the bodyweight without any adverse events. However, it is strongly recommended that the button be removed within a year to prevent refractory enterocutaneous fistula formation.
