RESUMO
BACKGROUND: The optimal neoadjuvant chemotherapy (NAC) regimen for patients with localized pancreatic ductal adenocarcinoma (PDAC) remains uncertain. This trial aimed to evaluate the efficacy and safety of two neoadjuvant chemotherapy (NAC) regimens, gemcitabine plus nab-paclitaxel (GA) and gemcitabine plus S-1 (GS), in patients with resectable/borderline-resectable (R/BR) PDAC. PATIENTS AND METHODS: Treatment-naïve patients with R/BR-PDAC were enrolled and randomly allocated. They received two cycles (2 months) of each standard protocol, followed by radical surgery for those without tumor progression in general hospitals belonging to our intergroup. The primary endpoint was to determine the superior regimen on the basis of achieving a 10% increase in the rate of patients with progression-free survival (PFS) at 2 years from allocation. RESULTS: A total of 100 patients were enrolled, with 94 patients randomly assigned to the GS arm (N = 46) or GA arm (N = 48). The 2-year PFS rates did not show the stipulated difference [GA, 31% (24-38%)/GS, 26% (18-33%)], but the Kaplan-Myer analysis showed significance (median PFS, GA/GS 14 months/9 months, P = 0.048; HR 0.71). Secondary endpoint comparisons yielded the following results (GA/GS arm, P-value): rates of severe adverse events during NAC, 73%/78%, P = 0.55; completion rates of the stipulated NAC, 92%/83%, P = 0.71; resection rates, 85%/72%, P = 0.10; average tumor marker (CA19-9) reduction rates, -50%/-21%, P = 0.01; average numbers of lymph node metastasis, 1.7/3.2, P = 0.04; and median overall survival times, 42/22 months, P = 0.26. CONCLUSIONS: This study found that GA and GS are viable neoadjuvant treatment regimens in R/BR-PDAC. Although the GA group exhibited a favorable PFS outcome, the primary endpoint was not achieved.

BACKGROUND: In pancreatic ductal adenocarcinoma (PDAC), invasion of connective tissues surrounding major arteries is a crucial prognostic factor after radical resection. However, why the connective tissues invasion is associated with poor prognosis is not well understood. MATERIALS AND METHODS: From 2018 to 2020, 25 patients receiving radical surgery for PDAC in our institute were enrolled. HyperEye Medical System (HEMS) was used to examine lymphatic flow from the connective tissues surrounding SMA and SpA and which lymph nodes ICG accumulated in was examined. RESULTS: HEMS imaging revealed ICG was transported down to the paraaortic area of the abdominal aorta along SMA. In pancreatic head cancer, 9 paraaortic lymph nodes among 14 (64.3%) were ICG positive, higher positivity than LN#15 (25.0%) or LN#18 (50.0%), indicating lymphatic flow around the SMA was leading directly to the paraaortic lymph nodes. Similarly, in pancreatic body and tail cancer, the percentage of ICG-positive LN #16a2 was very high, as was that of #8a, although that of #7 was only 42.9%. CONCLUSIONS: Our preliminary result indicated that the lymphatic flow along the connective tissues surrounding major arteries could be helpful in understanding metastasis and improving prognosis in BR-A pancreatic cancer.

BACKGROUND: Robotic gastrectomy(RG)for gastric cancer(GC)has been covered by health insurance since 2018. In this study, we examined the results of RG for GC at our hospital during the initial period of its introduction. MATERIALS AND METHOD: From August 2022 to May 2023, we retrospectively examined the surgical outcomes and short-term postoperative outcomes of the first 9 patients who underwent RG for GC at our hospital. RESULTS: The median patient age was 77(67-82) years, gender was 4 males and 5 females, and distal gastrectomy was performed in all patients. The median operative time was 410(323-486)min, blood loss was 5(1-140)mL, postoperative hospital stay was less than 9 days in all patients, and there was no conversion to laparoscopic or open surgery. There were no postoperative complications of Clavien-Dindo Grade â ¡ or above. CONCLUSION: In this study, RG for GC was performed safely without intraoperative or postoperative complications.

BACKGROUND: Duke pancreatic mono-clonal antigen type 2 (DUPAN-II) is a famous tumour maker for pancreatic cancer (PC) as well as carbohydrate antigen 19-9 (CA19-9). We evaluated the clinical implications of DUPAN-II levels as a biological indicator for PC during preoperative chemoradiation therapy (CRT). METHODS: This retrospective analysis included data from 221 consecutive patients with resectable and borderline resectable PC at diagnosis who underwent preoperative CRT between 2008 and 2017. We focused on 73 patients with elevated pre-CRT DUPAN-II levels (> 230 U/mL; more than 1.5 times the cut-off value for the normal range). Pre- and post-CRT DUPAN-II levels and the changes in DUPAN-II ratio were measured. RESULTS: Univariate analysis identified normalisation of DUPAN-II levels after CRT as a significant prognostic factor (hazard ratio [HR] = 2.06, confidence interval [CI] = 1.03-4.24, p = 0.042). Total normalisation ratio was 49% (n = 36). Overall survival (OS) in patients with normalised DUPAN-II levels was significantly longer than that in 73 patients with elevated levels (5-year survival, 55% vs. 21%, p = 0.032) and in 60 patients who underwent tumour resection (5-year survival, 59% vs. 26%, p = 0.039). CONCLUSION: Normalisation of DUPAN-II levels during preoperative CRT was a significant prognostic factor and could be an indicator to monitor treatment efficacy and predict patient prognosis.

The anastomotic technique after esophagectomy is of great interest in the prevention of anastomotic complications that adversely affect postoperative recovery. This study aimed to compare the clinical outcomes of modified Collard (MC) and circular stapled (CS) anastomoses after esophagectomy. A total of 504 consecutive patients with thoracic esophageal cancer who underwent esophagectomy and cervical esophagogastric CS or MC anastomosis from January 2013 to December 2019 were enrolled. Out of 504 patients, 134 and 370 underwent CS and MC anastomoses. The frequency of anastomotic leakage and stricture was significantly lesser in the MC group than in the CS group (3.0 vs. 10.5%, P = 0.0014 and 11.1 vs. 34.3%, P < 0.001, respectively). CS anastomosis was an independent risk factor for anastomotic stricture (odds ratio, 4.89; P < 0.001). Oral intake was significantly higher in the group without anastomotic stricture than in the group with anastomotic stricture at 2, 3, and 6 months postoperatively (P < 0.001, P = 0.013, and P < 0.001, respectively). The percentage body weight loss (%BWL) was -12.2% in the group with anastomotic stricture and -7.5% in the group without anastomotic stricture at 3 months postoperatively (P = 0.0012). Anastomotic stricture was an independent factor associated with %BWL (odds ratio, 4.86; P = 0.010). Propensity score-matched analysis, which included 88 pairs of patients, confirmed a significantly lower anastomotic stricture rate in the MC group than in the CS group (10.2 vs. 35.2%, P < 0.001). MC anastomosis is better than CS anastomosis for reducing the frequency of anastomotic stricture, which may be useful for maintaining early postoperative nutritional status.

A 79-year-old man was scheduled for surgery for hepatocellular carcinoma(HCC)after transcatheter hepatic arterial embolization for rupture. Two weeks before surgery, the patient came to our hospital with a chief complaint of back pain. First, we performed biliary drainage, under the diagnosis of HCC with obstructive jaundice due to haemobilia. Hepatectomy was performed when the patient's condition stabilized. It should be kept in mind that haemobilia may occur after TAE for HCC with bile duct tumor thrombus, and appropriate treatment should be performed when bleeding occurs.

We report a case of colon metastasis from gastric cancer treated by laparoscopic-assisted segmental colectomy. An 81-year-old man was undergone distal gastrectomy, D2 dissection and Billroth â reconstruction for gastric cancer 3 years previously, with a final diagnosis of gastric cancer L, Post, Type 2, sig/por2, pT4a(SE), pN3b(30/56), H0, P0, M0, pStage â ¢C. Three years after gastrectomy, CT scan showed an elevated lesion in the transverse colon, which was suspected to be metastatic colorectal cancer on closer examination. As no metastatic lesions were found other than the tumor of transverse colon, we performed laparoscopic-assisted segmental colon resection. A small incision was placed in the umbilical region, and the transverse colon was extracted from the umbilical region after dissection of the adhesions by single-incision laparoscopic surgery. The transverse colon containing the mass lesion was partially resected extracorporeally and reconstructed with a functional end-to-end anastomosis. The postoperative pathological findings revealed tumor cells predominantly below the submucosal layer and partly showing the signet ring cell carcinoma, and the transvers colon tumor was diagnosed as a metastasis from gastric cancer. The postoperative course was uneventful and the patient was discharged 8 days after surgery, and is alive for 10 months after the segmental colon resection followed by chemotherapy.

We report a case of recurrent esophageal cancer with long-term survival treated by S-1 monotherapy. A 66-year-old man underwent subtotal esophagectomy, two-field lymphadenectomy after 2 courses of DCF chemotherapy for esophageal cancer 1 year earlier. The final diagnosis was esophageal cancer, Lt, CT-Type 2, ypT3, ypN0(0/62), M0, ypStage â ¢. At 6 months after esophagectomy, CT scan revealed mediastinal lymph node metastasis and pleural dissemination, and paclitaxel monotherapy was performed, but lymph node re-enlargement was observed on CT at 12 months after esophagectomy. Chemotherapy with S-1 monotherapy was performed, and 3 months after initiation of S-1 monotherapy, CT showed reduced lymph node metastases and pleural dissemination remained reduced. Adverse events were CTCAE v5.0 Grade 2 thrombocytopenia and diarrhoea, but no Grade 3 or higher adverse events were observed. Long-term survival was achieved with no disease progression for more than 2.5 years after initiation of S-1 monotherapy.

A 50-year-old man presented with fecaluria and was diagnosed with sigmoid colon cancer with a colovesical fistula. Total bladder resection was determined to be necessary for curative resection at the time of diagnosis. In anticipation of bladder preservation, 6 courses of mFOLFOX6 plus panitumumab were administered after transverse colostomy, resulting in marked tumor regression and a decision to proceed with surgery. The patient underwent robotic-assisted low anterior resection of the rectum and partial cystectomy, which yielded pathological radical treatment. We report a case of sigmoid colon cancer with a colovesical fistula complicated by bladder invasion, in which preoperative chemotherapy was effective and total cystectomy was avoided, allowing bladder preservation.

Here we report the case of a patient with advanced gastric cancer who presented with duodenal intramural metastasis based on the pathological results after surgery. The patient was 78-year-old female, who was referred to our department for further evaluation and treatment of upper abdominal pain. An upper gastrointestinal series demonstrated a tumor occupying the lesser curvature of the gastric body. Biopsy specimens from the tumor demonstrated moderately to poorly differentiated adenocarcinoma. A computed tomography scan showed thickening of the gastric wall and swelling of the regional lymph nodes. The patient underwent distal gastrectomy and D2 lymph node dissection for gastric cancer. A histopathological examination disclosed that the gastric tumor was poorly differentiated adenocarcinoma with severe lymphatic permeation and also demonstrated the other poorly differentiated adenocarcinoma occupying the part of the muscularis propria layer of the duodenum. The gastric tumor was not contiguous with the duodenal tumor, and the duodenal cancer cells had the same pathological characteristics as the primary gastric cancer cells; therefore, we diagnosed the duodenal tumor as an intramural metastasis from gastric cancer. The patient's disease was staged as pT4aN3bM1, Stage â £ according to the TNM classification. We report this rare case along with a discussion of the literature.

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.

BACKGROUND: Laparoscopic Billroth-I gastroduodenostomy using a delta-shaped anastomosis is safe and feasible. However, it is often difficult to perform in patients who have a short posterior wall of the duodenum. Thus, we have developed a new method named duodenal overlap functional anastomosis with linear stapler (DOLFIN). We hereby report the technical details of the new method and our preliminary experience performing it. METHODS: After the completion of lymphadenectomy, the duodenum was transected craniocaudally with an endoscopic linear stapler. The hepatoduodenal mesentery was dissected approximately 4 cm along the duodenal bulb, and the anastomosis between the posterior wall of the stomach and the lesser curvature of the duodenum was created. The common entry hole was then transected using an endoscopic linear stapler, and the anastomosis was finally completed. RESULTS: There were 36 patients with gastric cancer who underwent laparoscopic distal gastrectomy (LDG) or robotic distal gastrectomy (RDG) with B-I reconstruction using DOLFIN. There were no postoperative complications classified as C-D grade 3 or more and complications related to anastomosis, such as anastomotic leak or stenosis. CONCLUSIONS: Our DOLFIN gastroduodenostomy can be performed safely. In addition, it results in good postoperative outcomes. A long-term comparative study is required to further evaluate the clinical usefulness of this method.

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.

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.

BACKGROUND: We analyzed the short-term outcomes and nutritional assessment of gastric cancer surgery patients who underwent exercise intervention after gastrectomy. MATERIALS AND METHOD: Gastric cancer patients who underwent gastrectomy at our department from January 2021 were included in the study. Postoperative exercise intervention(lower limb training) was performed in gastric cancer patients aged 75 years or older(group H: 7 patients)and compared retrospectively with gastric cancer patients younger than 75 years(group L: 10 patients)who did not receive exercise intervention. The rate of decrease in each index after 1 week was compared between the 2 groups. RESULTS: Postoperative complications(yes/no) were 3/4(42.8%)in group H and 2/8(20.0%)in group L(p=0.59); postoperative hospital stay was 11.5(10.8-21.3) days in group H and 11.0(9.0-14.0)days in group L(p=0.37). The percentage decrease in each index was as follows: for BMI in groups H/L: 2.9/5.6%(p=0.17), grip strength in groups H/L: 2.4/ï¼7.6%(p=0.07), skeletal muscle mass in groups H/L: ï¼2.3/7.0%(p=1.00), PNI in groups H/L: 26.6/18.1%(p=0.12). CONCLUSION: In this study, no significant differences were noted in postoperative complication rates or postoperative hospital stay between groups H and L.

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.

PURPOSE: Pancreaticoduodenectomy (PD) concomitant with portal vein resection (PVR) often develops into digestive varices with an occurrence rate of 30-50%, and the variceal bleeding is sometimes untreatable and results in fatality. Against this issue, splenic artery (SpA) ligation during PD-PVR is emerging as an easy and effective prophylactic surgical option. The aim of this study was to investigate the significance of SpA ligation in the development of digestive varices in patients undergoing PD-PVR. METHOD: We retrospectively investigated 97 patients with PDAC who received PD-PVR in two hospitals. Vascular reconstruction of the splenic vein (SpV) was not performed in either hospital. We assessed the occurrence rate of digestive varices in these patients in association with the performance of SpA ligation. RESULTS: The occurrence rate of digestive varices was 23%. SpA ligation was the only significant decreasing factor for the development of digestive varices (odds ratio 0.3, p = 0.035). Although SpV resection was not a significant risk factor for the development of digestive varices in all patients, SpV resection was a significant risk factor for the development of digestive varices in patients without SpA ligation, as demonstrated in previous reports. SpA ligation did not increase surgical complications or impair pancreatic function. CONCLUSION: PD-PVR surgery was accompanied by a 23% incidence of digestive varices, and SpA ligation significantly decreased the development of digestive varices without causing clinically significant complications. TRIAL REGISTRATION: No. 18196 (Osaka International Cancer Institute) and no. 19006 (National Hospital Organization Osaka National Hospital).

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.

BACKGROUND: Postoperative atrial fibrillation (POAF) after esophagectomy for esophageal cancer is not uncommon. The aim of this study is to examine whether preoperative transthoracic echocardiography is useful for predicting new-onset POAF in esophageal cancer. METHODS: In this prospective observational study, we evaluated 200 patients with esophageal cancer who underwent esophagectomy at our hospital between January 2016 and July 2019. Conventional echocardiographic assessment and tissue Doppler imaging were performed before surgery. We investigated the utility of preoperative transthoracic echocardiography for predicting new-onset POAF in esophageal cancer. RESULTS: New-onset POAF occurred in 51 (25.5%) of 200 patients. POAF was significantly associated with older age (p = 0.007), higher body mass index (p = 0.020), preoperative hypertensive disease (p = 0.021), and lower hemoglobin level (p = 0.028). The incidence of postoperative complications was significantly higher in patients with POAF than in patients without POAF (43.1% vs. 24.2%, p = 0.013). Transthoracic echocardiography showed that left atrial diameter (LAD) and E wave/e' wave ratio (E/e') were significantly higher in patients with POAF than in patients without POAF (34.1 vs. 31.3 mm, p < 0.001 and 11.6 vs. 10.5, p = 0.003, respectively). Multivariate analysis showed that LAD ≥ 36.0 mm, E/e' ≥ 8.4 are independent risk factors for POAF (odds ratios 2.47 and 3.64; p values 0.035 and 0.027, respectively) CONCLUSIONS: Preoperative echocardiographic evaluation is useful for predicting the onset of POAF after esophagectomy for esophageal cancer. Risk stratification using LAD and E/e' enables clinicians to identify patients at high risk for POAF before esophagectomy.

BACKGROUND: Esophageal cancer patients sometimes have a history of previous gastrectomy. To determine whether we should resect or preserve the remnant stomach, we need to understand the frequency and sites of abdominal lymph node (LN) metastasis from esophageal cancer after gastrectomy. PATIENTS AND METHODS: In 46 patients with thoracic esophageal squamous cell carcinoma (ESCC) who had a history of previous gastrectomy due to gastric cancer (n = 20) or benign disease (n = 26), the frequency and sites of any LN metastasis including LN metastasis at surgery and LN recurrence were investigated. The factors associated with abdominal LN metastasis were also examined. RESULTS: The incidence of metastasis to cervical, mediastinal, and abdominal LNs at surgery was 10.8%, 30.4%, and 30.4%, respectively. The incidence of abdominal LN recurrence was 6.5%. Of 46 patients, 16 patients (34.8%) had any abdominal LN metastasis, including abdominal LN metastasis at surgery or abdominal LN recurrence. There was no significant difference in the incidence of any abdominal LN metastasis between the gastric cancer group and the benign disease group (25.0% vs. 42.3%, p = 0.222). Clinically, nodal status was identified as the only independent factor associated with the occurrence of any abdominal LN metastasis, although neither tumor location nor the reason for gastrectomy was. CONCLUSIONS: The present study showed that the incidence of abdominal LN metastasis from ESCC after gastrectomy was not necessarily low, regardless of the tumor location and the reason for previous gastrectomy. This result suggests that gastrectomy should not be omitted easily in ESCC patients after previous gastrectomy.
