RESUMO
PURPOSE: Near-infrared fluorescence imaging using indocyanine green (ICG-NIFI) can visualize a blood flow in reconstructed gastric tube; however, it depends on surgeon's visual assessment. The aim of this study was to re-analyze the ICG-NIFI data by an evaluator independent from the surgeon and feasibility of creating the time-intensity curve (TIC). METHODS: We retrospectively reviewed 97 patients who underwent esophageal surgery with gastric tube reconstruction between January 2017 and November 2022. From the stored ICG videos, fluorescence intensity was examined in the four regions of interest (ROIs), which was set around the planned anastomosis site on the elevated gastric tube. After creation the TICs using the OpenCV library, we measured the intensity starting point and time constant and assessed the correlation between the anastomotic leakage. RESULTS: Postoperative leakage occurred for 12 patients. The leakage group had significantly lack of blood flow continuity between the right and left gastroepiploic arteries (75.0% vs. 22.4%; P < 0.001) and tended to have slower ICG visualization time assessed by the surgeon's eyes (40 vs. 32 s; P = 0.066). TIC could create in 65 cases. Intensity starting point at all ROIs was faster than the surgeon's assessment. The leakage group tended to have slower intensity starting point at ROI 3 compared to those in the non-leakage group (22.5 vs. 19.0 s; P = 0.087). CONCLUSION: A TIC analysis of ICG-NIFI by an independent evaluator was able to quantify the fluorescence intensity changes that the surgeon had visually determined.

BACKGROUND: The purpose of this study was to compare the results of the hybrid mediastino-thoracoscopic approach with that of the conventional thoracoscopic approach and to identify the advantages and disadvantages of the hybrid approach. METHODS: We retrospectively analyzed 172 patients who underwent thoracoscopic esophagectomy for esophageal cancer from July 2009 to June 2021, excluding salvage surgery. In the mediastinoscopic approach, the lymph nodes were dissected from a small incision in the left aspect of the neck to the aortic arch with supine double-lung ventilation. Thereafter, the middle-to-lower mediastinum and right superior mediastinum were dissected thoracoscopically in the prone position. The patients' demographics, surgical outcomes, postoperative complications, and postoperative recurrence patterns were compared between 51 patients in the hybrid approach and 121 patients in the conventional approach. RESULTS: The hybrid group had more elderly patients (71 years vs. 67 years; P = 0.010), more cardiovascular disease (33.3% vs. 16.7%; P = 0.021), lower rates of preoperative chemotherapy (49.0% vs. 69.4%; P = 0.015), and shorter right lung collapse time (196 min vs. 264 min; P < 0.001). Postoperative hoarseness was not different between the two groups (31.4% vs. 27.3%; P = 0.584), and there was a significant difference in the sternal-vertebral distance at the level of the sternal notch (41 mm in the hybrid group vs. 48 mm in the conventional group; P = 0.029). The sternal-vertebral distance of less than 45 mm was an independent risk factor for postoperative hoarseness in the logistic analysis (odds ratio 3.636, 95% confidence interval 1.054-12.546; P = 0.041). CONCLUSION: The hybrid mediastino-thoracoscopic approach could be safely adapted to elderly or cardiopulmonary diseased patients; however, short sternal-vertebral distance might be a risk factor of postoperative recurrent laryngeal nerve palsy.

A 72-year-old female with type 1 diabetes, a history of interstitial pneumonia, and diabetic ketoacidosis was admitted to our hospital with dysphagia. Endoscopy revealed a circumferential neoplastic lesion in the upper to middle esophagus, and a biopsy revealed squamous cell carcinoma. Computed tomography revealed invasion of the left main bronchus, and induction chemotherapy was initiated with a diagnosis of unresectable locally advanced esophageal cancer. After one course of induction chemotherapy, the tumor size reduced, bronchial invasion improved, and thoracoscopic esophagectomy was performed. During surgery and until 3 days after surgery, the patient's blood glucose level was controlled using an artificial pancreas, and the target blood glucose range was set at 140-180 mg/dL. On the fourth postoperative day, the patient was managed using a sliding scale. Mean blood glucose was 186.7 ± 70.0 mg/dL for 3 days before surgery, 190.5 ± 25.0 mg/dL during artificial pancreas therapy from the surgery to the next day, 169.8 ± 22.0 mg/dL during artificial pancreas therapy on the second to third postoperative days, and 174.5 ± 25.0 mg/dL during sliding scale therapy for 4-15 days after surgery. No hypoglycemia or ketoacidosis was noted.
RESUMO
The blood supply of the right gastroepiploic artery after esophagectomy with gastric tube reconstruction is essential for avoiding anastomotic leakage. Near-infrared fluorescence (NIRF) imaging with indocyanine green is widely used to assess the blood supply because it can visualize it in real-time during navigation surgery. However, there is no established protocol for this modality. One reason for this lack of protocol is that NIRF provides subjective information. This study aimed to evaluate NIRF quantification. We conducted a literature review of risk factors for anastomotic leakage after esophagectomy, NIRF procedures, NIRF quantification, and new methods to compensate for NIRF limitations. Major methods for the quantification of NIRF include measuring the blood flow speed, visualization time, and fluorescence intensity. The cutoff value for the blood flow speed is 2.07 cm/s, and that for the visualization time is 30-90 s. Although the time-intensity curve provided patterns of change in the blood flow, it did not show an association with anastomotic leakage. However, to compensate for the limitations of NIRF, new devices have been reported that can assess tissue oxygenation perfusion, organ hemoglobin concentration, and microcirculation.

We report the case of a long-term-surviving adolescent and young adult patient with unresectable advanced gastric cancer for whom multidisciplinary treatment was effective. A 29-year-old woman was referred to our hospital for further examination following a diagnosis of gastric cancer by a local physician. Esophagogastroduodenoscopy showed a deep ulcerated lesion in the lower third of the stomach, and analysis of biopsy specimens revealed an adenocarcinoma. Abdominal contrast- enhanced computed tomography showed gastric wall thickening in the lower third of the stomach. The patient underwent distal gastrectomy with lymph node dissection, including resection of localized peritoneal metastases, followed by Roux-en- Y reconstruction. The pathological diagnosis was serosa-invading poorly differentiated adenocarcinoma with 1 lymph node metastasis measuring 6.0×5.5 cm in the posterior wall of the lower third of the stomach and negative immunohistochemical staining for human epidermal growth factor receptor 2. The patient received postoperative chemotherapy with S-1 and oxaliplatin. She developed bilateral ovarian metastases measuring 13.0 cm and 7.8 cm after 17 months. The patient presented with severe lower abdominal pain and underwent an emergency bilateral ovarian metastasectomy, which revealed torsion of the right ovarian tumor, which had twisted twice on its pedicle, and a left ovarian mass. After the operation, 41 courses of ramucirumab with nab-paclitaxel were administered as a second-line treatment, and she received systemic drug treatment. Sixty months after the gastrectomy, the patient developed left hydronephrosis due to peritoneal metastases and was treated with nivolumab after ureteral stent replacement. No effective treatment was proposed in cancer multigene panel testing, and she died 66 months after the initial treatment because of disease progression. Comprehensive multidisciplinary treatment, including surgical and local therapy for peritoneal dissemination based on drug therapy for unresectable advanced gastric cancer, may result in long-term survival. Further research and accumulation of such cases would lead to the development of novel treatments.

PURPOSE: This study aimed to analyze the clinicopathological features and treatment outcomes of ovarian metastasis from gastric cancer. METHODS: This study included 155 female patients with unresectable advanced or recurrent gastric cancer at the Kochi Medical School between January 2007 and December 2021. A review of patients with ovarian metastasis was conducted, and their clinicopathological information and survival outcomes were compared with respect to ovarian metastasis. RESULTS: Fifteen patients were diagnosed with ovarian metastasis from gastric cancer with a median age of 54 years (range: 30-87 years) and an incidence of 9.7%. The median age of patients who developed ovarian metastasis was significantly lower those without ovarian metastasis (54 years vs. 71 years, P = 0.014). The median survival time (MST) for 15 patients with unresectable advanced gastric cancer who developed ovarian metastasis was 21.4 months (range: 0.2-41.4 months). The MST for 15 patients who underwent surgical resection and systemic drug treatment including chemotherapy to ovarian metastasis was significantly higher than those who received systemic drug treatment alone (28.1 months vs. 10.0 months; P = 0.021). CONCLUSION: Ovarian metastasis was found in 9.7% of female patients with unresectable advanced or recurrent gastric cancer and in younger patients than in those without ovarian metastasis. Multidisciplinary treatment, including surgical resection and systemic drug treatment for ovarian metastasis from gastric cancer, may benefit selected patients.

PURPOSE: This study evaluated the prognostic value of C-reactive protein-to-albumin (CAR) and neutrophil-to-lymphocyte ratios (NLR) in conjunction with host-related factors in patients with unresectable advanced or recurrent gastric cancer. METHODS: A total of 411 patients with unresectable advanced gastric cancer were treated at Kochi Medical School between 2007 and 2019. Associations between clinicopathological parameters and systemic inflammatory and nutritional markers, including CAR and NLR, with overall survival were analyzed retrospectively. RESULTS: The optimal cut-off values of predicted median survival time were 0.096 (sensitivity, 74.9%; specificity, 42.5%) for CAR and 3.47 (sensitivity, 64.1%; specificity, 57.5%) for NLR, based on the results of receiver operating characteristic analysis. A weak significant positive correlation was identified between CAR and NLR (r = 0.388, P < 0.001). The median survival time was significantly higher in patients with intestinal-type than those with diffuse-type histology (18.3 months vs. 9.5 months; P = 0.001), CAR < 0.096 than those with CAR ≥ 0.096 (14.8 months vs. 9.9 months; P < 0.029), and those with NLR < 3.47 than NLR ≥ 3.47 (14.7 months vs. 8.8 months; P < 0.001). Multivariate survival analysis revealed that diffuse-type histology (hazard ratio (HR) 1.865; 95% confidence interval (CI) 1.397-2.490; P < 0.001)), 1 or more performance status (HR 11.510; 95% CI 7.941-16.683; P < 0.001), and NLR ≥ 3.47 (HR 1.341; 95% CI 1.174-1.769; P = 0.023) were significantly associated with independent predictors of worse prognosis. CONCLUSIONS: High CAR and NLR are associated with poor survival in patients with unresectable and recurrent gastric cancer.

PURPOSE: Patients with unresectable advanced metastatic gastric cancer have a poor prognosis. This study examined the incidence and prognostic impact of cachexia during systemic drug treatment in such patients. METHODS: We enrolled patients with unresectable advanced gastric cancer who were treated with chemotherapy at Kochi Medical School from 2007 to 2020. Cancer cachexia was defined as > 5% weight loss or > 2% weight loss with a body mass index of < 20 kg/m2 within the past 6 months. Associations between clinicopathological parameters, cancer cachexia, and the overall survival were analyzed. RESULTS: Cancer cachexia occurred in 55.2% of 134 enrolled patients 6 months after chemotherapy. The incidence of cancer cachexia in initial unresectable gastric cancer was significantly higher than that in patients with recurrent cancer after curative resection. The median overall survival was significantly lower in the patients with cancer cachexia than in those without cancer cachexia at 6 months after starting systemic chemotherapy (13.7 months vs. 21.6 months, P = 0.032). Cancer cachexia at 6 months of starting treatment and CRP > 0.14 were identified as significantly associated with poor outcomes in a multivariate analysis (hazard ratio [HR] 1.339, 95% confidence interval [CI] 1.160-2.085, P = 0.019; HR 1.885, 95% CI 1.124-3.161, P = 0.016); respectively). CONCLUSIONS: Cancer cachexia was frequently observed in unresectable advanced gastric cancer patients who received chemotherapy and was useful as a prognostic factor for the overall survival.

Metastasis to the central nervous system from gastric cancer is exceedingly uncommon. We report a gastric cancer patient with cerebral metastasis during the period when durable response was obtained by systemic drug treatment using nivolumab. A 78-year-old male was referred to our hospital for further examination following diagnosis of gastric cancer by a local medical doctor. Esophagogastroduodenoscopy showed a slightly elevated lesion with central depressed area in the upper-third of the stomach, and analysis of biopsy specimens revealed an adenocarcinoma. The patient underwent laparoscopic total gastrectomy with lymph nodes dissection followed by Roux-en-Y reconstruction, resulting in submucosal invasive carcinoma and no lymph node metastasis. The patient developed solitary splenic metastasis measuring 4.2 cm after 28 months later, and the patient underwent a splenectomy, since there was no evidence of further metastatic lesions in any other organs. Subsequently, the patient was received S-1 plus oxaliplatin chemotherapy based on negative immunohistochemical staining of the resected specimens for human epidermal growth factor receptor 2. Four months after the splenectomy, the patient developed multiple liver metastases and was treated with ramucirumab plus paclitaxel. Because of disease progression, the patient was administered 3 mg/kg, iv, nivolumab every 2 weeks. After 4 courses of systemic treatment using nivolumab, abdominal computed tomography revealed marked shrinkage of the liver metastases. After 12 courses of nivolumab, the liver metastases had disappeared completely. The patient developed hypothyroidism, which could be controlled by thyroid hormone replacement treatment. The patient continues to receive nivolumab, and there is no evidence of disease recurrence in the 33 month period since starting nivolumab. However, he developed cerebral metastases after 69 months after surgery, complaining of articulation disorder. The patient underwent tumor resection by craniotomy followed by radiation therapy; however, he died 3 months after the operation. Although brain metastasis arising from gastric cancer is rare, future identification of risk factors and development of novel treatments are desired by further investigations and accumulation of these cases.

BACKGROUND: This study aimed to investigate the efficacy of enteral supplementation of vitamin B12 for vitamin B12 deficiency in patients who underwent total gastrectomy for gastric cancer. METHODS: The study enrolled 133 patients who underwent total gastrectomy for gastric cancer at Kochi Medical School. Clinical data were obtained to investigate associations between vitamin B12 supplementation and vitamin B12 levels. Vitamin B12 deficiency was defined as serum vitamin B12 less than 200 pg/mL. Baseline characteristics and changes in hematological variables, including vitamin B12 levels, were examined. RESULTS: Vitamin B12 deficiency was present in 71.4% of the 133 patients. Vitamin B12 levels at 3, 6, and 12 months after enteral supplementation were 306 pg/mL, 294 pg/mL, and 367 pg/mL, respectively, which were all significantly higher than those before supplementation (p < 0.001 for all comparisons). The median red blood cell count at 3, 6, and 12 months after enteral supplementation were 380 × 104/mm3, 394 × 104/mm3, and 395 × 104/mm3, respectively, which were all significantly higher than those before supplementation (p = 0.020, p = 0.001, and p = 0.003, respectively). Vitamin B12 levels at 3, 6, and 12 months after supplementation were significantly higher in patients supplemented enterally than those supplemented parenterally (p < 0.001 for all comparisons). CONCLUSIONS: Vitamin B12 deficiency was found in 71.4% of postoperative patients who underwent total gastrectomy for gastric cancer, and enteral vitamin B12 supplements might be effective to improve anemia in these patients.

PURPOSE: Zinc is an essential dietary component for humans and the second most prevalent trace element; however, serum zinc levels after gastrectomy have not been fully elucidated. This study aimed to evaluate the correlation between clinicopathologic features and serum zinc levels in patients who underwent gastrectomy for gastric cancer. METHODS: The study enrolled 617 patients who underwent gastrectomy for gastric cancer at the Kochi Medical School. Clinical data were obtained to investigate associations between clinicopathological features, including nutritional indicators and serum zinc levels. Serum zinc deficiency was defined as serum zinc level < 80 µg/dL. RESULTS: The median zinc level of the 617 patients was 73 µg/dL (range, 31-144 µg/dL), and serum zinc deficiency was present in 68.6% of patients. Median age was significantly higher in the zinc low level group than in the normal group (69 vs. 66 years, P < 0.001). Albumin was significantly lower in the zinc low level group than in the normal group (3.9 vs. 4.2 g/dL, P < 0.001). C-reactive protein level was significantly higher in the zinc low level group than in the normal group (0.12 vs. 0.10 mg/dL, P = 0.014). The median serum zinc level was significantly lower in the patients who received chemotherapy after gastrectomy than in those who were not received chemotherapy (72 vs. 76 µg/dL, P < 0.001). Serum zinc levels showed a significant positive correlation with serum albumin (r = 0.505, P = 0.044). Multivariate analysis showed that serum albumin level was significantly associated with serum zinc level (ß = 0.489, P < 0.001). CONCLUSIONS: Serum zinc deficiency was found in 68.6% of postoperative patients who underwent gastrectomy for gastric cancer, which was highly correlated with serum albumin.

Mesenteric lymph node metastasis of gastric cancer is extremely rare. We report the case of a patient with advanced gastric cancer having lymph node metastasis in the transverse mesocolon who underwent gastrectomy with lymph node dissection followed by chemotherapy. A 74-year-old male complaining of tarry stool was referred to our hospital for further examination following a diagnosis of gastric cancer by a local medical doctor. Esophagogastroduodenoscopy revealed an irregular and ulcerated lesion in the lower third of the stomach, and analyses of biopsy specimens revealed adenocarcinoma. Abdominal computed tomography revealed abdominal wall thickening in the lower third of the stomach, with enlarged lymph nodes in the perigastric area and the left side area of the middle colic artery. With a clinical diagnosis of gastric cancer, the patient underwent distal gastrectomy with lymph node dissection followed by Billroth â reconstruction. During surgery, the enlarged lymph node along with the middle colic artery in the transverse mesocolon was dissected. The gross appearance of the resected specimen shows a large and ulcerated tumor measuring 6.0×5.5 cm in the lesser curvature side of the lower third of the stomach. The pathological examination of the resected specimen showed solid-type poorly-differentiated adenocarcinoma with lymph nodes metastases, which was detected in the perigastric area and transverse mesocolon. The final diagnosis according to the Japanese classification of gastric carcinoma by the Japanese Gastric Cancer Association was L, Less-Post-Ant, Type 2, 6.0×5.5 cm, T3(SS), N2(5/19), M1(LYM), P0, H0, CY0, por1, Ly0, V1a, Stage â £, R0. Subsequently, the patient received S-1 plus oxaliplatin chemotherapy; however, he developed para-aortic lymph node metastases 18 months after surgery. Therefore, the patient was treated with ramucirumab plus nab-paclitaxel and was alive 20 months after the operation. Although mesocolonic lymph node metastasis of gastric cancer is rare, future identification of risk factors and the development of novel treatments should be achieved through further investigations and the accumulation of 3 cases.

BACKGROUND: The present study sought to evaluate host-related factors as predictors in patients receiving chemotherapy for recurrent advanced gastric cancer. METHODS: Sixty-three patients were enrolled in the study and received chemotherapy for recurrent gastric cancer at the Kochi Medical School from 2008 to 2015. Clinicopathological information and systemic inflammatory response data were obtained retrospectively to investigate associations between baseline cancer-related prognostic variables and survival outcomes. RESULTS: The median survival time was significantly higher for patients with a Glasgow prognostic score (GPS) of 0 compared to a GPS of 1 or 2 (18.2 vs. 7.1 months; p = 0.006), and for patients in the normal range for carbohydrate antigen-125 (CA125) compared to higher levels (17.9 vs. 4.1 months; p = 0.003). There was no significant influence on overall survival by age, gender, disease status, metastatic site, time to recurrence, carcinoembryonic antigen level, CA19-9 level, prognostic nutrition index, or neutrophil to lymphocyte ratio according to the results of the univariate log-rank tests. Multivariate survival analysis identified a GPS of 1 or 2 (hazard ratio, 3.520; 95% confidence interval, 1.343-9.227; p = 0.010) and a high CA125 level (hazard ratio, 3.135; 95% confidence interval, 1.276-7.697; p = 0.013) as significant independent predictors associated with a poorer prognosis in the studied group of cancer patients. CONCLUSIONS: A GPS of 1 or 2 and a high level of CA125 are independent predictors of a poorer prognosis in patients receiving chemotherapy for recurrent gastric cancer.

PURPOSE: To evaluate the correlation between blood supply speed in the gastric tube (GT), assessed by the intraoperative indocyanine green (ICG) fluorescence method, and postoperative endoscopic assessment (PEA) of the anastomosis or anastomotic leakage (AL). METHODS: The subjects of this retrospective analysis were 66 consecutive patients who underwent GT reconstruction using ICG fluorescence during esophageal surgery. We measured the ICG visualization time, from ICG injection to visualization at the top of the GT. We performed PEA on 54 patients and classified ulcer formation as involving less than or more than half of the circumference. RESULTS: PEA revealed that nine patients (16.7%) had an anastomotic ulcer involving more than half of the circumference and ten (15.4%) had AL. The ICG visualization time in these patients was significantly delayed compared with that in those with less than half of the circumference involved by ulcer formation (37 s vs. 27 s; P = 0.015) and without AL (36 s vs. 28 s; P = 0.045). Multivariate analysis revealed that delay in the ICG visualization time (> 36 s) of the pulled-up GT (odds ratio, 6.098; 95% confidence interval, 1.125-33.024; P = 0.036) was an independent risk factor associated with AL. CONCLUSION: Delay in the ICG visualization time of pulled-up GT was associated with ulcer formation on the anastomosis and AL after esophageal surgery.

PURPOSE: To investigate the usefulness of clinicopathological systemic inflammatory response and nutritional biomarkers for predicting the efficacy of nivolumab in patients with advanced gastric cancer. METHODS: The subjects of this study were 29 patients who received nivolumab treatment for advanced gastric cancer at the Kochi Medical School between 2017 and 2019. Clinicopathological information, including systemic inflammatory response data, were obtained to investigate the associations between baseline cancer-related prognostic variables and survival outcomes. RESULTS: Immune-related adverse events (irAEs) of any grade were identified in 34.5% (10/29) of the patients. The median progression-free survival of patients with irAEs was significantly greater than that of patients without irAEs (5.8 months vs. 1.2 months, respectively; P = 0.028). The neutrophil to lymphocyte ratio (NLR) after 4 weeks of treatment in the complete response (CR) or partial response (PR) group was significantly lower than that in the stable disease (SD) or progression disease (PD) group (2.2 vs. 2.9, respectively; P = 0.044). The prognostic nutrition index (PNI) before treatment in the CR or PR group was significantly higher than that in the SD or PD group (37.1 vs. 32.1, respectively; P = 0.011). The PNI 8 weeks after treatment and the Glasgow prognostic score (GPS) before treatment were significantly associated with a poor outcome. CONCLUSION: The irAE, NLR, PNI, and GPS may be useful predictive markers for nivolumab efficacy in patients with advanced gastric cancer.

BACKGROUND: Our aim was to clarify the incidence of bowel obstruction associated with a feeding jejunostomy (BOFJ) after thoracoscopic esophagectomy and its association to characteristics and postoperative change in body weight. METHODS: We reviewed 100 consecutive patients who underwent thoracoscopic esophagectomy with gastric tube reconstruction and placement of a jejunostomy feeding catheter for esophageal cancer. The incidence of BOFJ was evaluated and the change in body weight after surgery was compared between patients with and without BOFJ. RESULTS: BOFJ developed in 17 patients. Compared to patients without BOFJ, those with BOFJ had a higher preoperative body mass index (23.3 kg/m2 versus 20.9 kg/m2, P = 0.022), and greater postoperative body weight loss rate: 3 month, decrease to 84.2% of initial body weight versus 89.3% (P = 0.002). Patients with BOFJ had shorter distance between the jejunostomy and midline (40 mm versus 48 mm, P = 0.011) compared to patients without BOFJ. On multivariate analysis, higher preoperative body mass index (odds ratio (OR) = 9.248; 95% confidence interval (CI) = 1.344-63.609; p = 0.024), higher postoperative weight loss at 3 months (OR = 8.490; 95% CI = 1.765-40.837, p = 0.008), and shorter distance between the jejunostomy and midline (OR = 8.160; 95% CI = 1.675-39.747, p = 0.009) were independently associated with BOFJ. CONCLUSION: Patients of BOFJ had greater preoperative body mass, shorter distance between jejunostomy and midline, and greater postoperative weight loss.

A 72-year-old woman was referred to our hospital for further examination of para-aortic lymph node swelling and elevated carbohydrate antigen 19-9 levels. Thirteen years ago, she had undergone distal gastrectomy for gastric cancer, and the final diagnosis was T4N1M0, Stage â ¢A. Abdominal contrast-enhanced computed tomography(CT)showed an enlarged para-aortic lymph node measuring 25 mm. Endoscopic ultrasound-guided fine-needle aspiration was performed, and biopsy specimens showed poorly differentiated adenocarcinoma. Under the clinical diagnosis of gastric cancer recurrence, the patient received chemotherapy with cisplatin plus S-1. After 5 cycles of systemic treatment, abdominal CT revealed a marked shrinkage of the para-aortic lymph node metastasis, with an 84% decrease. At 15 months after treatment, we switched to S-1 monotherapy because of general fatigue and the patient's preference. However, 22 months after the treatment, the patient was treated with ramucirumab due to the progression of para-aortic lymph node metastasis. After 33 months, the patient developed metastasis in the left ovary, measuring 11.0×8.5 cm. Because there was no evidence of further metastatic lesions in any other organs, she underwent left oophorectomy. After 37 months, the patient developed metastasis in the left cerebellum, measuring 3.2×2.5 cm, accompanied with headache and nausea. The patient underwent metastasectomy of the left cerebellum as palliative treatment. Simultaneous physical examination revealed a painful nodular elevated lesion in the subcutaneous tissue of the posterior neck region, measuring 18×15 cm. Pathological examination of the biopsy specimen showed infiltration of poorly differentiated adenocarcinoma cells into the subcutaneous mass. The patient received radiation therapy; however, she died due to septic shock with hydronephrosis 39 months after starting chemotherapy. Although late recurrence of gastric cancer is rare, identification of risk factors and the development of novel treatments should be achieved through further studies and accumulation of data from such cases.

PURPOSES: To establish the safety of laparoscopic-assisted colorectal resection for colorectal cancer in elderly patients aged ≥80 years. METHODS: Data were obtained from a chart review of patients who underwent colorectal cancer resection between 2009 and 2014 in Kochi Medical School. The effect of patient age on the extent of lymph node dissection and operative safety was assessed by comparing the short-term results of elderly patients with those of younger patients after propensity score matching. RESULTS: Of a total of 506 patients with colorectal cancer, 398 underwent laparoscopic surgery and 23% of these patients were aged ≥80 years old. The elderly patients tended to have poorer general condition and larger tumors, although no significant differences were found in tumor invasion, lymph node metastasis, or synchronous distant metastasis between the groups. After adjustment for preoperative factors, we noted that the elderly patients tended to undergo less aggressive surgical resection (P = 0.01). Further analysis after including surgical factors for propensity score matching revealed a similar rate of complications in the two groups (24 vs. 25%, respectively; P = 0.85), and similar postoperative death rates and length of postoperative hospital stay. CONCLUSION: The findings of the present study demonstrate that laparoscopic surgery for colorectal cancer should not be avoided based on simply the age of the patient.

We report a very rare case of delayed necrosis of the reconstructed colon 6 months after esophagectomy.A 67-year-old male patient had undergone esophagectomy with gastric tube reconstruction for esophageal cancer in 2014. Subsequently, total gastrectomy and ileo-colon reconstruction via a retrosternal route was performed for gastric tube cancer in 2022. Six months later, he suffered acute chest pain and came to our hospital. Contrast-enhanced CT showed severe dilation of the reconstructed colon with poor enhancement of the wall opposite mesentery, without arterial obstruction. Endoscopy showed no ischemic changes in the esophago-ileum anastomosis; however, mucosal color change to black was observed in the reconstructed colon. We diagnosed ischemic colitis of the reconstructed colon and started conservative treatment; however, 18 days later, he developed a right pyothorax due to perforation of the reconstructed colon. We performed necrosed colectomy with right chest drainage and cervical esophageal fistula was made. Histopathological examination revealed mucosal detachment, thinning of the muscularis propria, and ghost-like appearance of crypt. If necrosis of the reconstructed colon is suspected in the late postoperative period, endoscopic findings of the colonic mucosa may be useful in determining surgical treatment, even in the absence of arterial blood flow obstruction.
RESUMO
The placement of a jejunostomy catheter during esophagectomy may cause postoperative bowel obstruction. The proximity of the jejunostomy site to the midline might be associated with bowel obstruction, and we have introduced laparoscopic jejunostomy (Lap-J) to reduce jejunostomy's left lateral gap. We evaluated 92 patients who underwent esophagectomy for esophageal cancer between February 2013 and August 2022 to clarify the benefits of Lap-J compared to other methods. The patients were classified into two groups according to the method of feeding catheter insertion: jejunostomy via small laparotomy (J group, n = 75), and laparoscopic jejunostomy (Lap-J group, n = 17). Surgery for bowel obstruction associated with the feeding jejunostomy catheter (BOFJ) was performed on 11 in the J group. Comparing the J and Lap-J groups, the distance between the jejunostomy and midline was significantly longer in the Lap-J group (50 mm vs. 102 mm; P < 0.001). Regarding surgery for BOFJ, the distance between the jejunostomy and midline was significantly shorter in the surgery group than in the non-surgery group (43 mm vs. 52 mm; P = 0.049). During esophagectomy, Lap-J can prevent BOFJ by placing the jejunostomy site at the left lateral position to the midline and reducing the left lateral gap of the jejunostomy.
