Abstract
Aim Dysphagia is one of the most common complications after esophagectomy. However, no study has investigated the long‐term postoperative outcomes in patients with postoperative dysphagia. Here, we aimed to identify risk factors for postoperative dysphagia and to investigate long‐term postoperative outcomes in such patients. Methods This study included 304 consecutive patients with thoracic esophageal cancer who underwent curative esophagectomy. They were diagnosed with postoperative dysphagia through a contrast videofluoroscopic swallowing study, and postoperative outcomes were compared based on swallowing function. Results In total, 112 patients (37%) were diagnosed with postoperative dysphagia. Older age, low BMI, and recurrent laryngeal nerve palsy were identified as independent risk factors for postoperative dysphagia. In the dysphagia group, a significantly larger number of patients developed in‐hospital pneumonia, and hospital stays were also significantly extended. After discharge, 37 (33%) patients with postoperative dysphagia developed pneumonia. Even more than 1 year after esophagectomy, a significantly larger number of patients (24 patients, 21%) with postoperative dysphagia developed pneumonia compared to those without postoperative dysphagia. Postoperative dysphagia was identified as an independent risk factor for out‐of‐hospital pneumonia. Regarding nutritional status, there was no difference in weight loss 1 year after esophagectomy, but significant weight loss was observed 2 years after esophagectomy in the dysphagia group. Conclusion Postoperative dysphagia was associated with both preoperative patient factors and surgical factors. Moreover, patients with postoperative dysphagia had long‐term and short‐term pneumonia risk. The personalization of long‐term follow‐up through more aggressive rehabilitation and nutritional guidance is required for patients with postoperative dysphagia.

Abstract
Background Gastric cancer with portal vein tumor thrombus (PVTT) is poor prognosis, and the treatment remains challenging. Regarding surgery, there are only reports of highly invasive laparotomy. We report some techniques of the completely robotic total gastrectomy with thrombectomy and portal vein reconstruction for the patient with gastric cancer and PVTT for the first time. Case presentation A 79-year-old man was diagnosed with a 5-cm gastric cancer on the side of the lesser curvature from the middle of the gastric body to the cardia. Computed tomography revealed a massive PVTT extending from the left gastric vein to the portal trunk (28 x 16 mm). There were no other distant metastases. After 3 cycles of the chemotherapy, the PVTT shrank to 19 x 12 mm. After obtaining informed consent from the patient, robotic total gastrectomy with regional lymphadenectomy and thrombectomy were performed. We used the da Vinci Xi Surgical System. A 3-cm incision was made at the umbilicus, and a wound retractor was placed. Five additional ports were placed. The right side suprapancreatic lymph nodes were performed at the time of the thrombectomy. It was important to identify the precise extent of the PVTT with intraoperative ultrasonography before the thrombectomy. After PVTT identification, the portal trunk was clamped above and below the tumor thrombus with vascular clips. The membrane on the anterior wall of the portal trunk around the PVTT was carefully incised with da Vinci Scissors. The tumor thrombus was completely enucleated without separation. The incised part of the portal trunk was reconstructed with continuous 5-0 synthetic monofilament nonabsorbable polypropylene sutures. After removing the vascular clamps, we made sure there was no leakage from the portal vein and no tumor thrombus remnants with intraoperative ultrasonography. Robotic total gastrectomy with lymphadenectomy and Roux-en-Y reconstruction were performed. The patient was discharged without complications. The patient has remained alive for 30 months after surgery. Conclusions Robotic total gastrectomy with thrombectomy and portal vein reconstruction is a safe, minimally invasive, and precise surgery. It may contribute to improved prognosis of gastric cancer with PVTT when combined with chemotherapy.

Abstract
We report a case of non-exposed endoscopic wall-inversion surgery(NEWS)performed by TANKO technique for gastric GIST. A 52-year-old man was diagnosed as having gastric GIST. A 2 cm-sized tumor was found in the lesser curvature of the middle body of the stomach, and an endoscopic biopsy revealed GIST. A 2.5 cm umbilical incision was made and TANKO surgery was performed. After seromyotomy around the tumor, the outer serosal muscularis was sutured closed to invert the tumor into the stomach. The inverted tumor was resected from the stomach wall and recovered using endoscopic techniques. NEWS is an operation developed to resect a tumor without exposing it into the abdominal cavity and is expected to avoid the risk of postoperative abdominal abscess and peritoneal dissemination. On the other hand, the TANKO is a procedure with excellent plastic technique and can be performed in this operation.

Abstract
AIM Digestive reconstruction after pharyngolaryngectomy with total esophagectomy (PLTE) remains challenging, with the optimal method remaining unclear. The current study aimed to clarify the short-term outcomes after PLTE and determine the optimal digestive reconstruction method. METHODS Based on a nationwide survey of 151 patients who underwent PLTE, outcomes of digestive reconstruction methods are described. RESULTS Among digestive reconstruction methods, a simple gastric tube was most frequently used (37.1%), followed by gastric tube combined with free graft transfer (FGT) (35.1%), gastric tube with microvascular anastomosis (22.5%), and other procedures (5.3%). Intraoperative evaluation of microcirculation (IOEM) was utilized in 29 patients (19.2%). Among the included patients, 66.9% developed any-grade complications, 41.0% developed severe complications, and 23.8% developed digestive reconstruction-related complications (DRRCs; leakage or necrosis). Reoperation within 30 days for any complications and DRRCs was required in 13.9% and 8.6% of the patients, respectively. Mortality within 90 days was observed in 4.6%. Among the three major methods, gastric tube combined with FGT promoted the least DRRCs in the gastric tube (P = .005), although the overall incidence of DRRCs was comparable. The use of IOEM was significantly associated with a reduction of severe DRRCs (P = .005). CONCLUSIONS Pharyngolaryngectomy with total esophagectomy is a high-risk surgery significantly associated with the occurrence of postoperative morbidity and mortality. Nonetheless, the addition of FGT can help prevent gastric tip complications, while IOEM can be an effective method for improving outcomes.

Abstract
Atezolizumab plus bevacizumab combination therapy is the first cancer immunotherapy that has shown efficacy in the treatment of hepatocellular carcinoma(HCC). We report a case of HCC with recurrent peritoneal dissemination for which atezolizumab plus bevacizumab combination therapy was effective. The patient, a 63-year-old man, underwent transarterial embolization(TAE)for ruptured HCC, and a mass with dissemination on the caudal side of liver S3 was observed. Laparoscopic lateral hepatic resection plus resection of the dissemination plus cholecystectomy was thus performed in September 2019. However, in November 2019, multiple peritoneal dissemination recurrence was observed, and lenvatinib therapy was initiated. In May 2020, PD was observed, and we had switched to sorafenib therapy. However, in October 2020, further tumor growth and rapid increase in tumor markers(AFP 25,668 ng/mL, PIVKA-Ⅱ 64,960 mAU/mL)were observed, and the patient was judged to have PD. Atezolizumab plus bevacizumab combination therapy was initiated in the same month. Subsequently, a CT scan in January 2021 showed a marked decrease in tumor size, indicating PR. The tumor markers have since normalized(AFP 5 ng/mL, PIVKA-Ⅱ 28 mAU/mL). The patient has been treated with atezolizumab plus bevacizumab combination therapy again and is maintaining PR as an outpatient.

Abstract
The patient was a 78-year-old man who underwent upper gastrointestinal endoscopy, revealing a sub-circumferential type 2 tumor in the lower body of the stomach. Histopathology revealed poorly differentiated adenocarcinoma. Computed tomography(CT)showed lymph node and liver metastasis(S6, S8), which corresponded to clinical Stage Ⅳ(cT4bcN2cM1 [HEP]). Five courses of XP therapy were administered for Stage Ⅳ disease. The sizes of the primary lesion and metastatic liver tumors were reduced, and a partial response was achieved. Distal gastrectomy and partial hepatectomy were performed. The resected specimen was diagnosed as ypT4b(transverse colon mesenteric), ypN0, ypM1(HEP). Thus, the final Stage was Ⅳ. During adjuvant chemotherapy with S-1, the para-aortic, left common iliac, and external peri-iliac lymph node metastases were detected by CT imaging 6 months after the operation. This prompted XP therapy resumption. The lymph node metastases worsened despite 2 additional XP courses. Progressive disease prompted the change in regimen to PTX plus RAM. After 7 courses, swollen lymph nodes were observed and CPT-11 was initiated. Since the disease continued to progress, nivolumab therapy was administered. The para-aortic, left common iliac, and external peri-iliac lymph nodes shrank after nivolumab initiation. The patient has responded well to nivolumab for more than 3 years without immunological adverse events.

Abstract
PURPOSE Intraoperative fluid restriction is reported to be associated with reduced postoperative tissue edema and decreased incidence of postoperative pancreatic fistula (POPF) in pancreatic surgery. However, there is limited information regarding the postoperative approach to prevent postoperative tissue edema and reduce POPF. METHODS Patients undergoing distal pancreatectomy from 2013 to 2018 in our institute were retrospectively enrolled (n = 128). The patients were classified into the two groups: an early diuresis group (ED group: patients administered diuretic agents on postoperative day 2 or earlier between 2016 and 2018, n = 69) and a conventional diuresis group (CD group: patients administered diuretic agents on postoperative day 3 or later between 2013 and 2015, n = 59). Postoperative tissue edema assessed by CT imaging and the incidence of clinically relevant POPF (CR-PF; grade B or C) were compared. RESULTS Postoperative tissue edema was significantly reduced in the ED group (p < 0.0001). The incidence of CR-PF was lower in the ED group (19% vs. 32%, p = 0.082), especially in patients with postoperative diuresis on POD 1 (12%, p = 0.044). CONCLUSION Early and aggressive postoperative diuresis potentially reduced postoperative visceral tissue edema. This postoperative approach to prevent tissue edema may reduce the incidence of CR-PF in pancreatic surgery.

Abstract
OBJECTIVE To compare short-term outcomes between two- vs. three courses of neoadjuvant chemotherapy (NAC) to clarify the optimal treatment for esophageal squamous cell cancer (ESCC) in a multicenter, randomized, phase II trial. BACKGROUND An optimal number of NAC cycles remains to be established for locally advanced ESCC. METHODS Patients with locally advanced ESCC were randomly assigned to either two (N = 91) or three (N = 89) courses of DCF (70 mg/m2 intravenous docetaxel and 70 mg/m2 intravenous cisplatin on day 1, and a continuous 700 mg/m2 fluorouracil infusion for 5 days) every 3 weeks followed by surgery. We compared the two groups for perioperative parameters, adverse events, and the response to NAC. RESULTS The two- and three-course groups showed similar completion rates and overall NAC dose reductions. Although the two-course group showed significantly lower overall grades 3-4 leukopenia and anemia compared to the three-course group, the two groups had similar overall toxicity rates. Postoperative complications were not significantly different between the two groups, except arrhythmia (13 vs. 0%, P = 0.0007). Only two postoperative in-hospital deaths occurred in the three-course group, due to sepsis following severe pneumonia. Compared to the two-course group, the three-course group was associated with a significantly better clinical response (42.9 vs. 65.2%, P = 0.0027) and a relatively higher rate of pathological complete response (9.1 vs. 15.3%, P = 0.212). CONCLUSION Both two- and three-course DCF regimens in the NAC setting seemed to be equally feasible in locally advanced ESCC patients. Additional DCF courses led to a better NAC response without increasing the incidence of adverse events or postoperative morbidity.

Abstract
Background Ligation clips are used for vessel or tissue ligation in surgery. Although previous reports have described the migration of metallic clips after hepato-biliary-pancreatic surgery, very few reports have described the migration of non-absorbable polymer clips (NAPCs: Hem-o-Lok). Case presentation We present 4 cases of NAPC migration that occurred after laparoscopic surgery. Case 1 was an 81-year-old woman that had undergone a laparoscopic right hemihepatectomy for an intrahepatic bile duct cyst adenocarcinoma at the age of 79 years. Two years after the operation, she underwent an upper gastrointestinal endoscopy to investigate epigastric pain. The endoscopy showed NAPCs lodged at the anterior side of the duodenal bulb. Case 2 was an 80-year-old man that had undergone a laparoscopic cholecystectomy for choledocholithiasis at the age of 77 years. Three years after the operation, follow-up computed tomography and magnetic resonance cholangiopancreatography (MRCP) imaging indicated a mass in the upper bile duct. After a laparoscopic bile duct resection and reconstruction, an NAPC was found inside the inflammatory pseudotumor. Case 3 was a 63-year-old man that had undergone laparoscopic liver S4b and S5 resections and lymph node dissection for gallbladder cancer. Three months after the operation, follow-up MRCP imaging suggested a bile duct stenosis. An endoscopic retrograde cholangiopancreatography (ERCP) was performed, and an NAPC was found inside the bile duct. Case 4 was a 74-year-old man that had undergone a laparoscopic S5 segmentectomy, S7 partial liver resection, and cholecystectomy for liver metastasis of lung cancer and cholelithiasis. A trans-cystic drainage tube was inserted, and it was ligated and fixed with NAPCs. Three months after the operation, follow-up MRCP imaging showed common bile duct stones (CBDS). An ERCP was performed, and two NAPCs were found with the CBDS. Conclusions Few previous reports have described complications due to NAPC migration after hepato-biliary-pancreatic surgery. However, with the widespread use of NAPC, postoperative complications due to NAPC migration are expected to increase in the near future. The differential diagnosis of complications should include potential NAPC migration in patients that have undergone laparoscopic surgery.

Abstract
Background Total mesorectal excision (TME) and lateral lymph node dissection (LLND) without radiotherapy (RT) are standard treatment for lower cT3/4 rectal cancers in Eastern countries. In comparative studies, both TME + LLND and RT + TME yield good local control. Although Japanese guidelines recommend LLND for locally advanced rectal cancers below the peritoneal reflection, LLND dissection of clinically negative lateral pelvic lymph nodes (LPLN) is controversial, and laparoscopic TME + LLND is technically challenging and time-consuming. New optical instruments for laparoscopy allow easy perioperative sentinel lymph node (SLN) identification using ICG. The SLN concept may facilitate accurate diagnosis of LPLN involvement, and thus reduce LLND in laparoscopic rectal cancer surgery. Here we investigated lateral pelvic SLN navigation surgery for SLN detection during laparoscopic rectal cancer surgery. Methods This study included 21 patients with clinical StageII/III lower rectal cancer without LPLN enlargement, who underwent curative laparoscopic surgery. All patients underwent TME, followed by lateral SLN identification and biopsy using ICG, and then laparoscopic LLND. ICG fluorescence imaging was conducted using the laparoscopic near-infrared camera system. Results Lateral SLNs were successfully identified in 16 (76.2%) of the 21 patients. Among the 15 patients without SLN tumor metastasis, the dissected lateral non-SLNs were all negative. Conclusions A lack of metastasis in the lateral pelvic SLN seems to reflect a lack of metastases to all lateral LNs. Our present results suggest that this laparoscopic ICG-guided SLN strategy may be a low-risk and time-saving method to prevent laparoscopic LLND in cases with negative lateral pelvic lymph nodes.

Abstract
BACKGROUND/AIM An excessive postoperative inflammatory response is correlated with the development of pneumonia and an unfavourable prognosis in patients undergoing esophagectomy for esophageal cancer. We assessed the influence of OSK-0028, a synthetic human ghrelin on inflammatory response and energy metabolism, on the postoperative course of patients following radical esophagectomy. PATIENTS AND METHODS Esophageal cancer patients were randomly assigned to low-dose (LD; 0.25 μg/kg/h) or high-dose (HD; 0.5 μg/kg/h) intravenous OSK-0028 or placebo for 7 days after esophagectomy. The primary endpoint was serum interleukin-6 level on postoperative day (POD) 3. RESULTS A total of 75 patients were enrolled (23 LD, 26 HD, 26 placebo). The median interleukin-6 levels on POD 3 were 40.95, 35.85, and 64.50 pg/ml in the placebo, LD, and HD groups, respectively, with no significant differences (p=0.78). Postoperative complications did not differ between groups. Bodyweight loss was significantly lower in patients receiving OSK-0028 than in those receiving placebo (-0.17% vs. 1.78%, p=0.043). CONCLUSION Although OSK-0028 did not attenuate inflammatory response after esophagectomy, it prevented postoperative bodyweight loss.

BACKGROUND Transcription-reverse transcription concerted reaction (TRC) is recognized as a useful method for detecting free cancer cells in the peritoneal cavity and predicting peritoneal recurrence in patients with gastric cancer. Nonetheless, the clinical significance of TRC in laparoscopic surgery remains unclear. This study aimed to evaluate the clinical importance of carcinoembryonic antigen (CEA) messenger RNA (mRNA) level in peritoneal lavage fluids measured by TRC in laparoscopic surgery for locally advanced gastric cancer. METHODS We enrolled patients with locally advanced gastric cancer who underwent laparoscopic gastrectomy. Peritoneal lavage fluids were collected prior to gastrectomy, and the TRC method was employed to quantify CEA mRNA in peritoneal washes. Overall survival (OS), recurrence-free survival (RFS), and peritoneal recurrence-free survival (PRFS) were analyzed using the Kaplan-Meier method and compared using the log-rank test. Adjusted Cox proportional hazards regression models were used to calculate the hazard ratios (HRs) for CEA mRNA positivity. RESULTS A total of 100 patients were analyzed in this study. Overall, 22 patients (22%) exhibited CEA mRNA positivity in peritoneal lavage fluids, as measured by TRC. No significant association between CEA mRNA levels and clinicopathological characteristics was observed. Patients who were CEA mRNA-positive in peritoneal lavage fluids had significantly worse OS, RFS, and PRFS than those who were CEA mRNA-negative (p = 0.0059, p < 0.0001, and p = 0.0022, respectively). In the univariate Cox model, the HR for all-cause mortality in CEA mRNA-positive versus CEA mRNA-negative patients was 3.60 (95% CI, 1.33-9.55; p = 0.0129). Multivariate analysis revealed that CEA mRNA positivity was a significant independent factor for recurrence. CONCLUSIONS TRC enables the detection of free cancer cells in the peritoneal cavity and CEA mRNA levels can help predict the prognosis, even in laparoscopic gastrectomy.

Thoracic Duct Resection Has a Favorable Impact on Prognosis by Preventing Hematogenous Spread of Esophageal Cancer Cells: A Multi-institutional Analysis of 2269 Patients. Ann Surg Oncol 2021; 28:4402-4410.

Abstract
BACKGROUND The impact of thoracic duct (TD) resection on prognosis is controversial. This study aimed to examine the impact of TD resection. METHODS In this six-institution, matched-cohort study, 2269 consecutive patients with esophageal squamous cell carcinoma who underwent esophagectomy between 2000 and 2017 were enrolled for analysis of long-term outcomes, including overall survival (OS), disease-free survival (DFS), cause-specific survival (CSS), and recurrence patterns. RESULTS Based on a propensity score, 642 TD-resected and 642 TD-preserved patients with all stages of disease were selected. At 5 years, the TD-resected group had an OS of 57.7%, a DFS of 50.9%, and a CSS of 62.2%. These rates were significantly higher than the corresponding rates of 48.7% (p = 0.0078), 41.0% (p = 0.0297), and 55.3% (p = 0.0473) in the TD-preserved group. The OS in the TD-preserved and TD-resected groups was similar for the patients with cStage 1 or 2 (p = 0.6265), but it was significantly higher in the TD-resected group for the patients with cStage 3 or 4 (p = 0.0052). The incidence of total recurrence did not differ between the two groups. However, the incidence of hematogenous recurrence in the TD-resected group (19.0%) was significantly lower than in the TD-preserved group (26.2%) (p = 0.0021). For cT4a tumors, the incidence of local recurrence in the TD-resected group (2.4%) was significantly lower than in the TD-preserved group (18.4%) (p = 0.0183). CONCLUSIONS Performance of TD resection may help to improve prognosis, especially for patients with advanced esophageal squamous cell carcinoma, by reducing hematogenous and local recurrence. Prospective trials are needed to determine whether prophylactic TD resection has a positive impact on the prognosis of patients with esophageal cancer.

A phase II study of the safety of olanzapine for oxaliplatin based chemotherapy in coloraectal patients. Sci Rep 2021; 11:4547. [PMID: 33633328 PMCID: PMC7907185 DOI: 10.1038/s41598-021-84225-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2020] [Accepted: 02/05/2021] [Indexed: 11/17/2022] Open
Abstract
Olanzapine has exhibited efficacy as an antiemetic agent when used with 5-HT3 receptor antagonists, dexamethasone, and NK1 receptor antagonists for patients receiving highly emetogenic chemotherapy. In addition, several studies have reported the efficacy or safety of olanzapine in patients receiving moderately emetogenic chemotherapy, including carboplatin, irinotecan, and oxaliplatin. However, no reports of olanzapine use have focused on patients receiving oxaliplatin-based chemotherapy. Therefore, we analyzed the safety of antiemetic therapy using olanzapine, palonosetron, aprepitant, and dexamethasone in colorectal cancer patients undergoing oxaliplatin-based chemotherapy. This study was a prospective phase II single-institution study of 40 patients (median age 60 years, 23 patients were male). The primary endpoint was the incidence of adverse events, and the exploratory endpoints were the rate of chemotherapy-induced nausea and vomiting. Almost all patients (90%) had a performance status of 0. All patients received the scheduled antiemetic therapy. The most common adverse event was somnolence (n = 7 patients, 17.5%). All adverse events were grade 1. Thirty-six patients were included in the exploratory analysis of efficacy. No patients experienced vomiting during the first 120 h after chemotherapy, and complete response and complete control were both 86.1%. The rate of total control was 55.6% during the same time period. Olanzapine use with 5-HT3 receptor antagonists, dexamethasone, and NK1 receptor antagonists was safe for colorectal cancer patients receiving oxaliplatin-based chemotherapy.

Abstract
Background Peutz–Jeghers syndrome (PJS) is a very rare autosomal dominant genetic disorder characterized by hamartomatous polyps in the gastrointestinal tract and hyperpigmentation of the lips, hands, and feet. The hamartomatous polyps in the small intestine often cause intussusception and bleeding. Case presentation A 62-year-old male was hospitalized for treatment of deep vein thrombosis and pulmonary embolism. In the small intestine, computed tomography showed three small polyps with intussusceptions. Since the patient had gastrointestinal polyposis and pigmentation of his lips, fingers, and toes, he was diagnosed with PJS. After an inferior vena cava filter was placed, he underwent laparoscopic-assisted surgery. The polyps causing intussusception were resected as far as possible without intestinal resection, since they had caused progressive anemia and might cause intestinal obstruction in the future. The patient was discharged from the hospital on postoperative day 9 without complications. Conclusions Laparoscopic-assisted disinvagination and polypectomy is a useful, minimally invasive treatment for multiple intussusceptions caused by small intestinal polyps in patients with PJS.

Abstract
AIM The aim is to report the long-term outcomes of preoperative cisplatin and fluorouracil plus docetaxel (DCF) vs Adriamycin (ACF) for resectable esophageal squamous cell carcinoma (ESCC). Previously, this trial showed that DCF is associated with prolonged recurrence-free survival (RFS). METHODS Patients were randomly assigned to two cycles of ACF (35 mg/m2 of Adriamycin, 70 mg/m2 of cisplatin intravenously on day 1, and 700 mg/m2 of fluorouracil infusion for 7 days) every 4 weeks or DCF (70 mg/m2 of docetaxel, 70 mg/m2 of cisplatin intravenously on day 1, and 700 mg/m2 of fluorouracil infusion for 5 days) every 3 weeks, followed by surgery. The primary endpoint was RFS. The secondary endpoint was overall survival (OS). RESULTS Between October 2011 and October 2013, 162 patients at 10 institutions were enrolled in the study, 162 of whom were eligible and randomly assigned to the two groups. The median follow-up for surviving patients was 69.8 months. The 5-year RFS was significantly better in the DCF group than in the ACF group (59.9% vs 40.7%, hazard ratio [HR] 0.55; 95% confidence interval [CI], 0.35-0.86; P = .009) and the 5-year OS was significantly better in the DCF group than in the ACF group (63.5% vs 49.4%, HR, 0.61; 95% CI, 0.38-0.96; P = .03). The benefit of DCF chemotherapy on survival was significantly greater in the subgroups with more advanced clinical T and N stage. CONCLUSIONS Cisplatin and fluorouracil plus docetaxel are associated with better RFS and OS than ACF in resectable ESCC patients.

Abstract
OBJECTIVE This prospective randomized phase-II trial examined whether gastric reconstruction with duodenal diversion plus Roux-en-Y anastomosis(RY) minimized gastroduodenal reflux and delayed gastric emptying compared with standard gastric reconstruction. SUMMARY BACKGROUND DATA There is no established standard surgical procedure to prevent both gastroduodenal reflux and delayed gastric emptying simultaneously. METHODS Sixty patients with thoracic esophageal cancer scheduled to undergo esophagectomy with retrosternal gastric tube reconstruction were randomly allocated to standard gastric reconstruction (non-RY, n = 31) or gastric reconstruction with duodenal diversion plus RY (n = 29) groups. Primary endpoint was quality of life assessed by DAUGS-32 score 1 year after surgery. Secondary endpoints were the extent of postoperative duodenal juice reflux into the gastric tube, postoperative morbidity, endoscopic findings, body weight changes, and nutritional status. RESULTS Preoperative clinicopathological characteristics and postoperative morbidity did not differ significantly between groups. However, operation time and blood loss volume were significantly higher in the RY group. Pancreatic amylase concentrations in the gastric conduit on postoperative days 2, 3, and 7 were higher in the non-RY group. Postoperative endoscopic examination showed residual gastric content in 7 of 17 patients in the non-RY group but in none in the RY group (P = 0.012). Quality of life was significantly favorable in the RY group with regard to reflux symptoms and food passage dysfunction. Postoperative body weight changes, serum albumin levels, and peripheral blood lymphocyte counts were not significantly different between groups. CONCLUSION Gastric reconstruction with duodenal diversion plus RY is effective in improving both gastroduodenal reflux and delayed gastric emptying.

Abstract
BACKGROUND Biological factors are emphasized in borderline resectable pancreatic cancer (BRPC), and CA19-9 is an important factor for biological borderline resectability (b-BR). The aim of this study was to investigate the cut-off value of CA19-9 for biological borderline resectability and "biological downstaging" in chemoradiation therapy (CRT) for pancreatic cancer (PC). METHODS A total of 407 patients with anatomically resectable PC (a-R) and BRPC (a-BR) received preoperative gemcitabine-based CRT. The b-BR was determined, according to the CA19-9 value prior to preoperative CRT (pre-CA19-9), as the subgroup of a-R cases in which the survival was comparable with that in a-BR cases. "Biological downstaging" was determined based on prognostic analyses regarding the CA19-9 value after preoperative CRT (post-CA19-9) in association with the survival of R cases (a-R cases without the b-BR factor). RESULTS The 5-year survival of a-R patients with pre-CA19-9 > 120 U/mL was comparable with that of a-BR patients (44% vs 34%, p = 0.082). The survival of b-BR patients with post-CRT CA19-9 ≤ 37 U/mL (normalized) was comparably favorable with that of R patients (56% vs 65%, p = 0.369). The incidence of distant recurrence was higher in b-BR patients without post-CA19-9 normalization than in those with post-CA19-9 normalization (70% vs 50%, p = 0.003), while the incidence of local recurrence was comparable between these two groups (12% vs 13%, p = 0.986). CONCLUSIONS Biological BRPC was determined to be an anatomically resectable disease with pre-CA19-9 > 120 U/mL, and post-CA19-9 normalization indicated "biological downstaging" in b-BR in the preoperative CRT strategy.

Minimally invasive surgery is feasible after preoperative chemotherapy for stage IV gastric cancer. Ann Gastroenterol Surg 2020; 4:396-404. [PMID: 32724883 PMCID: PMC7382436 DOI: 10.1002/ags3.12343] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/17/2020] [Revised: 03/11/2020] [Accepted: 03/18/2020] [Indexed: 12/23/2022] Open
Abstract
AIM To elucidate the safety and feasibility of minimally invasive surgery (MIS) as conversion surgery after chemotherapy for stage IV gastric cancer, we compared the background characteristics and clinical courses of patients who underwent open conversion surgery (open group) versus MIS (MIS group). METHODS We included 94 consecutive patients with stage IV gastric cancer who received chemotherapy followed by conversion surgery gastric resection from January 2011 to October 2019 at the Osaka International Cancer Institute in this analysis. RESULTS The open group included more patients who had macroscopic peritoneal metastasis and required splenectomy. However, other background characteristics, including preoperative chemotherapy duration, were comparable. The MIS group had significantly longer operative time (266 vs 339 minutes, P = .0039) and less operative blood loss (520 vs 10 mL, P < .0001). The incidence of postoperative complication of Clavien-Dindo grade II or higher was non-significantly lower (24.5% vs 9.8%, P = .058) and length of postoperative hospital stay was significantly shorter in the MIS group (12 vs 8 days, P < .0001). Even though the open group included more patients with more advanced (ypT4a or higher, or N3) disease, the MIS group had better recurrence free survival and overall survival (OS). Multivariate analysis revealed that N status (hazard ratio [HR], 4.39; 95% confidence interval [CI], 2.18-12.26; P < .0001) and T status (2.11; 1.05-4.36; P = .036) were independent prognostic factors for OS. MIS was not a negative prognostic factor for OS (HR, 0.44; 95% CI, 0.15-1.10; P = .081). CONCLUSION MIS can be safely performed as conversion surgery following chemotherapy for stage IV gastric cancer.

Abstract
BACKGROUND Preoperative weight loss in esophageal cancer is reported to be associated with a poor prognosis. However, the impact of postoperative weight loss on the prognosis of patients with esophageal cancer remains unclear. METHODS This study included 186 patients with esophageal squamous cell carcinoma who underwent surgery between January 2012 and January 2015. The relationship between weight loss 6 months after esophagectomy as well as the clinical factors and prognosis of patients was investigated. RESULTS The mean weight loss rate for all the patients was 9.3% at 3 months, 10.8% at 6 months, 11.1% at 12 months, and 11.4% at 24 months after surgery. The patients with severe weight loss 6 months after surgery (≥ 12%) exhibited lower serum albumin levels and a lower prognostic nutrition index 6 months after esophagectomy than the patients with moderate weight loss (< 12%; p = 0.011 and 0.009, respectively). Although overall survival did not differ significantly between the two groups, for all the patients, severe weight loss was significantly associated with shortened overall survival for the cStages 3 and 4 patients (3-year overall survival rate, 76.6% in the moderate group vs 54.5% in the severe group; p = 0.042). The multivariate analyses identified only severe weight loss as an independent factor associated with worse overall survival for the cStages 3 and 4 patients (p = 0.034). CONCLUSION This study showed that postoperative weight loss negatively affected the prognosis for patients with advanced esophageal cancer, indicating the necessity of administering nutritional interventions to these patients to prevent postoperative weight loss.
