RESUMO
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.

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.
RESUMO
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: 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.
RESUMO
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: 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.

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.

PURPOSE: Laparoscopic sleeve gastrectomy (LSG) drastically affects body composition. However, studies focusing on the association between the changes in the pre-and postoperative muscle mass and postoperative results are limited. We evaluated the association between changes in the muscle mass and weight loss and fat reduction. METHODS: This retrospective study included 29 consecutive patients who underwent both LSG and a bioelectrical impedance analysis (BIA) consecutively. We investigated changes in the body composition on the BIA and visceral fat area (VFA) on computed tomography and correlational changes in muscle mass with weight loss and fat reduction. RESULTS: The total weight loss (%TWL) 12 months after surgery was 30.9%. The VFAs pre- and postoperatively were 224 and 71.0 cm2, respectively. The fat mass (FM), percentage of FM, appendicular skeletal muscle mass (ASM), and skeletal muscle mass index (SMI) decreased from pre- to postoperatively (54.8 vs. 32.2 kg; 49.0 vs. 41.2%, 26.7 vs. 23.9 kg, 9.24 vs. 8.27, respectively), whereas the percentage of ASM (%ASM) increased (22.1 vs. 28.0%). The rate of change in %ASM positively correlated with weight loss and fat reduction (%TWL, rs = 0.65; %VFA loss, rs = 0.62). CONCLUSION: The rate of change in %ASM was positively correlated with weight loss and fat reduction.
RESUMO
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: 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.

BACKGROUND & AIMS: The straight leg raise (SLR) maneuver during high-resolution manometry (HRM) can assess esophagogastric junction (EGJ) barrier function by measuring changes in intraesophageal pressure (IEP) when intra-abdominal pressure is increased. We aimed to determine whether increased esophageal pressure during SLR predicts pathologic esophageal acid exposure time (AET). METHODS: Adult patients with persistent gastroesophageal reflux disease (GERD) symptoms undergoing HRM and pH-impedance or wireless pH study off proton pump inhibitor were prospectively studied between July 2021 and March 2022. After the HRM Chicago 4.0 protocol, patients were requested to elevate 1 leg at 45º for 5 seconds while supine. The SLR maneuver was considered effective when intra-abdominal pressure increased by 50%. IEPs were recorded 5 cm above the lower esophageal sphincter at baseline and during SLR. GERD was defined as AET greater than 6%. RESULTS: The SLR was effective in 295 patients (81%), 115 (39%) of whom had an AET greater than 6%. Hiatal hernia (EGJ type 2 or 3) was seen in 135 (46%) patients. Compared with patients with an AET less than 6%, peak IEP during SLR was significantly higher in the GERD group (29.7 vs 13.9 mm Hg; P < .001). Using receiver operating characteristic analysis, an increase of 11 mm Hg of peak IEP from baseline during SLR was the optimal cut-off value to predict an AET greater than 6% (area under the receiver operating characteristic curve, 0.84; sensitivity, 79%; and specificity, 85%), regardless of the presence of hiatal hernia. On multivariable analysis, an IEP pressure increase during the SLR maneuver, EGJ contractile integral, EGJ subtype 2, and EGJ subtype 3, were found to be significant predictors of AET greater than 6% CONCLUSIONS: The SLR maneuver can predict abnormal an AET, thereby increasing the diagnostic value of HRM when GERD is suspected.

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: 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.

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: In recent years, the number of patients requiring surgery for intra-thoracic stomach (ITS) has been increasing due to the effects of obesity and gibbus due to aging. The aim of this study is to assess the effects of the degree of hernia on the pathological conditions and surgical outcomes in ITS patients. METHODS: ITS was defined as cases in which over 50% of the stomach had deviated into the mediastinum by esophagogastric fluoroscopy and/or computed tomography, with 65 patients who underwent laparoscopic surgery as the initial surgery included. We compared the pathological conditions and surgical outcomes by dividing the subjects into 3 groups: Group A: 50%- < 75%; Group B: 75%- < 100%; and Group C: 100% (upside-down stomach), depending on the degree of deviation into the mediastinum of the stomach. RESULTS: The breakdown of patients was 33 in Group A, 21 in Group B, and 11 in Group C. Regarding the preoperative pathological conditions, Group C had a high body mass index (BMI) and a low score for factor V according to upper gastrointestinal endoscopy (p = 0.0109, p = 0.0062, respectively). While the surgical results indicated that the operation time was extended depending on the degree of hernia (p = 0.0051), there was no marked difference in other surgical outcomes or the postoperative course among the three groups, with a high degree of satisfaction. CONCLUSIONS: In the case of ITS, although the operation time was extended depending on the degree of the hernia, the surgical outcomes were the same, and overall good results were obtained.

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.

BACKGROUND: Despite a high degree of satisfaction with laparoscopic Heller-Dor surgery (LHD) for esophageal achalasia, some cases show no improvement in postoperative esophageal clearance. We investigated whether an objective evaluation is essential for determining the therapeutic effect of LHD. METHODS: We investigated the difference in symptoms, regarding esophageal clearance, using timed barium esophagogram (TBE), in 306 esophageal achalasia patients with high postoperative satisfaction who underwent LHD. Furthermore, these patients were divided into two groups, in accordance with the difference in postoperative esophageal clearance, in order to compare the preoperative pathophysiology, symptoms, and surgical results. RESULTS: Although the poor postoperative esophageal clearance group (117 cases, 38%) was mostly male and the ratio of Sigmoid type was high compared to the good postoperative esophageal clearance group (p = 0.046, p = 0.001, respectively); in patients with high surgical satisfaction, there was no difference in terms of preoperative symptom scores and surgical results. However, although the satisfaction level was high in the poor esophageal clearance group, the scores in terms of the postoperative dysphagia and vomiting were high (p = 0.0018 and p = 0.004, respectively). The AUC was 0.9842 upon ROC analysis regarding the presence or absence of clearance at 2 min following postoperative TBE and the postoperative feeling of difficulty swallowing score, with a cut-off value of 2 points (sensitivity: 88%, specificity: 100%) in cases with a high degree of surgical satisfaction. CONCLUSION: The esophageal clearance ability can be predicted by subjective evaluation, based on the postoperative symptom scores; so, an objective evaluation is not essential in cases with high surgical satisfaction.

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.

Peptic esophagitis can occur as a complication of laparoscopic Heller-Dor surgery (LHD) among patients with esophageal achalasia. The goal of this study was to identify the characteristics of patients who have developed peptic esophagitis following LHD surgery along with the risk factors associated with the occurrence of peptic esophagitis. Among the 447 cases consisting of esophageal achalasia patients who underwent LHD as the primary surgery, we compared the patient background, pathophysiology, symptoms, and surgical outcomes according to whether or not peptic esophagitis occurred following surgery. We also attempted to use univariate and multivariate analyses to identify the risk factors for peptic esophagitis occurring following surgery. Esophagitis following surgery was confirmed in 67 cases (15.0%). With respect to the patient backgrounds for cases in which peptic esophagitis had occurred, a significantly higher number were male patients, with a significantly high occurrence of mucosal perforation during surgery in terms of surgical outcomes, along with a high occurrence of esophageal hiatal hernias in terms of postoperative course (P = 0.045, 0.041, and 0.022, respectively). However, there were no significant differences in terms of age, BMI, disease duration, preoperative symptoms, esophageal manometric findings, esophageal barium findings, and esophageal clearance. A multivariate analysis indicated independent risk factors for the occurrence of peptic esophagitis following LHD as being male, the occurrence of mucosal perforation during surgery, and the occurrence of esophageal hiatal hernias. Peptic esophagitis occurred following LHD in 15% of cases. Independent risk factors for the occurrence of peptic esophagitis following LHD included being male, the occurrence of mucosal perforation during surgery, and the occurrence of esophageal hiatal hernias following surgery.

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.
