Abstract
BACKGROUND Inguinal herniation of the urinary bladder is uncommon and those descending into the scrotum are even rarer. Although open anterior repair has been used for inguinal bladder hernia, the efficacy of laparoscopic herniorrhaphy has been reported in recent years. CASE PRESENTATION A 63-year-old man presented with an irreducible right groin and scrotal bulge associated with voiding difficulty. Abdominal ultrasonography showed a dislocation of the urinary bladder descending into the right scrotum. Abdominal CT imaging revealed that a part of the bladder and small intestine was herniating into the scrotum through the internal inguinal ring and running laterally to the inferior epigastric artery. Under the diagnosis of indirect inguinal bladder hernia, the patient underwent trans-abdominal preperitoneal hernia repair (TAPP). The bladder herniated into the scrotum through the internal inguinal ring was replaced to the original position. Then the myopectineal orifice was exposed and covered with polypropylene mesh, where a horizontal peritoneal incision 4 cm above the hernia orifice, i.e., the high peritoneal incision approach (HPIA), allowed an easy peeling of the peritoneum and hernia sac. The patient's postoperative course was uneventful and the voiding difficulty resolved. The patient continued to do well without recurrence at 20 months after surgery. CONCLUSION Preoperative evaluation with abdominal ultrasonography and CT scan allowed a precise diagnosis of a groin hernia with voiding difficulty. TAPP with HPIA was useful in the treatment of inguinal bladder hernia because this technique facilitated a quick confirmation of the hernia contents, secure dissection of the whole protruded bladder, and adequate replacement of the bladder to the original position without any injury.

Abstract
We report a case of pulmonary tuberculosis developed during chemotherapy for colon cancer. A 78-year-old man with dyspnea was referred to our hospital for the treatment of transverse colon cancer with duodenal invasion. Chemotherapy was initiated for severe respiratory dysfunction associated with emphysema. After 3 months of chemotherapy, the patient required hospitalization because of severe general fatigue and appetite loss. Pneumonia occurred on the 9th hospital day. Antibiotic therapies with cefotiam hydrochloride or tazobactam/piperacillin were ineffective, his respiratory condition gradually decreased, and thus, endotracheal intubation was required. The patient was finally diagnosed with pulmonary tuberculosis by acid-fast staining of the sputum. Antituberculosis therapy with rifampicin, isoniazid, and streptomycin was effective, and acid-fast staining became negative after 2 weeks of antituberculosis therapy. However, he could not withdraw from the ventilator support and died of cancer progression on the 94th hospital day. Because chemotherapies induce immunosuppression, a targeted screening for latent tuberculosis infection should be performed in patients with colorectal cancer who are highly at risk for tuberculosis before starting chemotherapy, and pulmonary tuberculosis should be ruled out when a patient develops symptoms of pneumonia during chemotherapy.

Abstract
Background: Performing an intracorporeal esophagojejunostomy during laparoscopic-assisted total or proximal gastrectomy is challenging. We developed an ingenious method of overlapping esophagojejunostomy using a linear stapler to avoid stapler-related intraoperative complications. Methods: Following lymph node dissection, the esophagus was transected anterior-posteriorly. A linear stapler was used to divide the jejunum ∼20 cm distal to the Treitz ligament. A small enterotomy was then created 5 cm distal to the elevated jejunal stump to insert the linear stapler cartridge. An electronic knife was used to make a full-thickness incision, with the tip of the nasogastric tube (NGT) pressed against the posterior wall of the esophageal stump as a guide. Full-thickness sutures were placed on both the anterior and posterior walls of the entry hole in the esophageal stump to prevent the anvil fork from being misinserted into the submucosal layer of the esophagus. The thread on the posterior wall was guided through the port to the outside of the abdominal cavity, where the linear stapler was inserted to perform the side-to-side anastomosis. A 45-mm cartridge fork and an anvil fork were inserted into the elevated jejunum and esophageal stump entry holes, respectively, following which the esophageal stump was gently grasped. The thread on the posterior wall side was pulled from outside the abdominal cavity through the port. This step is necessary to close the gap between the esophageal and jejunal walls. After confirming that the anvil fork was not misinserted into the submucosal layer of the esophagus and that there was no gap between the esophagus and the elevated jejunum, the linear stapler was fired to create the anastomosis. The insertion hole was closed with hand-sewn sutures or linear staples to complete the esophagojejunostomy. Results: Eleven patients underwent this procedure with no anastomotic complications. Conclusions: This method enables us to perform an easier and more stable esophagojejunostomy.

Abstract
BACKGROUND Duplicated left gastric artery (LGA) is a rare anomaly. With an incidence of only 0.4%, its clinical significance remains largely unrecognized. CASE PRESENTATION A 65-year-old man underwent robot-assisted distal gastrectomy for early gastric cancer. After division of the left gastric vein in the left gastropancreatic fold, a slim LGA (LGA-1) was identified and dissected. Careful dissection of the left gastropancreatic fold toward the root of the celiac artery revealed another LGA (LGA-2), which was dissected without difficulty. Postoperative reevaluation of the three-dimensional-computed tomography (CT) angiography reconstructed using the preoperative CT scan identified a 2.7 mm LGA-1, branching from the splenic artery, and a 3.0 mm LGA-2, branching from the celiac artery. To the best of our knowledge, this is only the third reported case of a duplicate LGA in a patient who underwent laparoscopic gastrectomy. Our case is the first to report the use of robot surgery. CONCLUSIONS Although duplicate LGA is rare and receives little clinical attention, surgeons should keep this vascular anomaly in mind during preoperative evaluation since there is an increased risk for intraoperative bleeding during gastrectomy.

Abstract
Background: The lack of tension at the anastomosis site and the blood flow of the gastric conduit are important to prevent anastomotic leakage in the anastomosis of the esophagogastric conduit. This study reports a gastric conduit stump closure method using Endo GIA™ Radial Reload in end-to-side anastomosis of the esophagogastric conduit, especially focusing on blood flow. Methods: A 4-cm conduit was created to ensure an intramural vascular network. The gastric conduit was elevated to the neck through the posterior mediastinal route, and end-to-side anastomosis of the esophagus and gastric conduit was performed using a circular stapler. Closure of the gastric stump with an Endo GIA Radial Reload was performed 2 cm proximal to the anastomosis on the end side of the esophagogastric conduit. The lesser curvature of the stump of the gastric conduit is the most frequent site of anastomotic leakage as it has the least blood flow, and the pressure is highest when the pressure inside the gastric conduit increases. Therefore, the gastric conduit stump was closed using the Endo GIA Radial Reload to resect the intersection of the gastric stump and lesser curvature from which the gastric conduit was created. The gastric conduit stump is gently curved; therefore, the pressure applied to the gastric conduit stump could be dispersed when the intragastric pressure increases. Results: No anastomotic leakage was observed among the 21 patients who underwent this method. Conclusion: This method is a novel anastomosis method to prevent anastomotic leakage in an end-to-side anastomosis of the esophagogastric conduit.

Abstract
BACKGROUND Lung cancer is the leading cause of cancer deaths worldwide. Although lung cancer can metastasize to various organs such as the liver, lymph nodes, adrenal gland, bone, and brain, metastases to the digestive organs, especially the colon, are rare. CASE SUMMARY An 83-year-old man diagnosed with lung cancer received radiation and chemoimmunotherapy, resulting in a complete clinical response. One year after the initial lung cancer diagnosis, the patient presented with obstructive ileus caused by a tumor in the descending colon. An elective left hemicolectomy was successfully performed after the endoscopic placement of a self-expandable metallic stent (SEMS). Pathologically, the tumor of the descending colon was diagnosed as lung cancer metastasis. The postoperative course was uneventful, and the patient is in good condition 13 mo after surgery, with no signs of recurrence. The previous 23 cases of surgical resection of colonic metastasis from lung cancer were reviewed using PubMed to characterize their clinicopathological features and outcomes. CONCLUSION SEMS is useful for obstructive colonic metastasis as a bridge to surgery to avoid emergency operations.

Abstract
We present the first search for the pair production of dark particles X via K_{L}^{0}→XX with X decaying into two photons using the data collected by the KOTO experiment. No signal was observed in the mass range of 40-110 MeV/c^{2} and 210-240 MeV/c^{2}. This sets upper limits on the branching fractions as B(K_{L}^{0}→XX)<(1-4)×10^{-7} and B(K_{L}^{0}→XX)<(1-2)×10^{-6} at the 90% confidence level for the two mass regions, respectively.

Abstract
PURPOSE A research subgroup was established by the Japanese Society of Gastroenterological Surgery to improve the health care quality in the Chushikoku area of Western Japan. METHODS The records of four surgical procedures were extracted from the Japanese National Clinical Database and analyzed retrospectively to establish the association between hospital characteristics, defined using a combination of hospital case-volume and patients' hospital travel distance, and the incidences of perioperative complications of ≥ Grade 3 of the Clavien-Dindo classification after gastroenterological surgery. RESULTS This study analyzed 11,515 cases of distal gastrectomy for gastric cancer, 4,705 cases of total gastrectomy for gastric cancer, 4,996 cases of right hemicolectomy for colon cancer, and 5,243 cases of lower anterior resection for rectal cancer, with composite outcome incidences of 5.6%, 10.2%, 5.5%, and 10.7%, respectively. After adjusting for patient characteristics and surgical procedures, no association was identified between the hospital category and surgical outcomes. CONCLUSION The findings of our study of the Chushikoku region did not provide positive support for the consolidation and centralization of hospitals, based solely on hospital case volume. Our grouping was unique in that we included patient travel distance in the analysis, but further investigations from other perspectives are needed.

Abstract
BACKGROUND We focused on the lymphocyte-to-monocyte ratio (LMR), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR) and devised an inflammation-combined prognostic index (ICPI) as a prognostic marker of cancer-specific survival (CSS). METHODS We reviewed the clinicopathological data of 480 patients with gastric cancer undergoing curative laparoscopic gastrectomy between 2009 and 2019. This study examined the significance of LMR, NLR, PLR, and ICPI as cancer-specific prognostic markers. RESULTS In univariate analysis, tumor diameter, histological differentiation, pathological tumor-node-metastasis (pTNM) stage, LMR, NLR, PLR, C-reactive protein (CRP) level, carcinoembryonic antigen (CEA), and postoperative chemotherapy were significantly associated with CSS. In multivariate analysis, pTNM stage and CEA were the independent risk factors for CSS, although LMR, NLR, and PLR were not the independent risk factors for CSS. The ICPI formula was constructed using hazard ratios for three inflammation-based biomarkers with worse prognosis identified in the univariate analysis: LMR <4.315, NLR ≥2.344, and PLR ≥212.01, which were each scored as 1, with all remaining values pointed at 0. ICPI was calculated as follows: ICPI = 2.9 × LMR + 2.8 × NLR + 2.8 × PLR. The optimal cutoff value of ICPII was 2.9. On multivariate analysis, pTNM stage, CEA, and ICPI were independent prognostic factors for CSS. In the Kaplan-Meier survival analysis, CSS in the high ICPI group was significantly worse than that in the low ICPI group. CONCLUSION ICPI was devised as a novel predictive index for prognosis, and its usefulness was clarified.

Abstract
Despite recent advances in cancer treatments, pancreatic cancer has a dismal prognosis globally. Early detection of cancer cells and effective treatments for recalcitrant tumors are required, but the innovative therapeutic tools remain in development. Cancer-specific antigens expressed only on cancer cells may help resolve these problems, and antibodies to such antigens have potential in basic research and clinical applications. To generate specific antibodies that bind to proteins expressed on the surface of pancreatic cancer cells, we immunized mice with human pancreatic cancer MIA PaCa-2 cells, and isolated a hybridoma that produces a monoclonal antibody (mAb), named 12-13.8. This antibody was applied to molecular biological experiments such as immunocytochemistry, immunoblotting, flow cytometry, and immunoprecipitation. In addition, we showed that mAb 12-13.8 could accumulate in tumors, through in vivo experiments using cancer-bearing mice. Immunohistochemical staining of pancreatic and lung tumor tissues indicated that the increase of the staining strength by mAb 12-13.8 positively and inversely correlated with the patients' cancer recurrence and survival rate, respectively. We identified the FXYD5 protein as the target protein of mAb 12-13.8, by a human protein array screening system. The FXYD5 protein is overexpressed in various types of cancer and is modified by O-linked glycosylation. We confirmed the binding of the FXYD5 protein to mAb 12-13.8 by using FXYD5-knockout MIA PaCa-2 cells, and detailed epitope mapping identified amino acid residues 45-52 as the minimal peptide sequence. Our results indicate that mAb 12-13.8 could be a valuable tool for FXYD5 studies, and useful in diagnostic and drug delivery applications for cancer patients.

Abstract
Oxaliplatin, widely used as a chemotherapy drug for colorectal cancer, is known to cause various adverse reactions. In particular, special attention for the development of portal hypertension associated with porto-sinusoidal vascular disease is necessary, as it is a serious adverse life-threating reaction, although rare. We herein report a case of oxaliplatin-related portal hypertension that developed several years after oxaliplatin administration and led to esophageal varices and refractory massive ascites. Clinical physicians should be aware of the possibility of oxaliplatin-induced portal hypertension and its possible development over a long period after discontinuation of the drug.

Abstract
Background The increasing ratio of functional future liver remnant (functional %FLR) after modified associating liver partition and portal vein ligation/embolization for staged hepatectomy (modified-ALPPS) compared with portal vein embolization (PVE) has not been comprehensively evaluated. Purpose To compare the increasing ratio of functional %FLR between modified-ALPPS and PVE via technetium-99 m-galactosyl human serum albumin single-photon emission computed tomography (99mTc-GSA SPECT/CT) fusion imaging. Material and Methods Seven and six patients underwent modified-ALPPS (modified-ALPPS group) and PVE (PVE group) from 2015 to 2019. The functional %FLR on 99 mTc-GSA SPECT/CT fusion imaging was assessed before and 1 week (modified-ALPPS group) and 3 weeks (PVE group) after each procedure. The increasing ratio of functional %FLR (functional %FLR ratio) was calculated and compared between the two groups. Moreover, the hypertrophy ratio of future liver remnant volume (FLRV ratio) and atrophy ratio of embolized liver volume (.ELV ratio) were evaluated. Results The mean functional %FLR ratios of the modified-ALPPS group (1.47 ± 0.15) and the PVE group (1.49 ± 0.20) were comparable (p > .05). The median FLRV ratio of modified-ALPPS group (1.48) was higher than that of the PVE group (1.16), the median ELV ratio of the PVE group (0.81) was lower than that of the modified-ALPPS group (0.94), and the results significantly differed between the two groups (p < .05). Conclusion The increasing ratio of functional %FLR was comparable between modified-ALPPS and PVE. Compared with PVE, ALPPS was associated with a higher hypertrophy rate of the remnant liver but a lower atrophy rate of the embolized liver.

Abstract
Background and Objective Robot-assisted surgery is particularly useful in esophagectomy for esophageal cancer because robotic systems have high-resolution three-dimensional imaging, tremor filtering, and articulated instruments. This review article focuses on the applications and limitations of surgical devices in robot-assisted minimally invasive esophagectomy (RAMIE). Methods A narrative search of Medline was performed for articles published using the keywords “robot-assisted esophagectomy”, “technique”, “postoperative complication”, and “short-term outcomes”. Key Contents and Findings Monopolar scissors: these devices with a sharp tip have an articulating function that allows for fast, sharp dissection without an electrical source. However, scissor-type devices cannot compress the organ, and their hemostatic ability is rather weak. Maryland bipolar forceps: the device has a very thin tip that allows for accurate dissection as well as stronger hemostatic ability by closing the forceps to compress tissues and applying electric current. The disadvantage is longer operation time because the forceps need to be constantly closed and reopened. Long Maryland bipolar grasper: the tip of the long Maryland bipolar grasper is slightly blunt and has the advantage of versatility because it can grip the tissue more delicately. Ultrasonic scalpel: the device can transect tissues speedily without bleeding, shortening operation time, but lacks articulating function. Although thermal spread to the surroundings is relatively narrow, activation time increases with the amount of tissue to be grasped; this raises the temperature above that of the vessel sealer. Vessel sealer: the device is one of the most powerful hemostatic energy devices, based on bipolar electrodes. The articulating jaws on both sides are more suited for sharp transection rather than meticulous dissection because of its powerful hemostatic force and blunt tip. It is also important to note that the vessel sealer produces widespread high-temperature steam. SynchroSeal: the device offers fast activation time, and due to the tip of the device being finely divided, which requires relatively precise manipulation. Conclusions Robot-assisted surgery reduces the limitations of conventional endoscopic surgery by offering stable high-resolution three-dimensional imaging, tremor filtering, and articulated instruments. It is important to understand and exploit the advantages of energy devices suitable for RAMIE.

Abstract
BACKGROUND Despite advances in surgical techniques, long-term survival after esophagectomy for esophageal cancer remains unacceptably low, and more effective perioperative chemotherapy is expected. However, an important concern regarding the application of postoperative adjuvant chemotherapy is treatment toxicity. We aimed to evaluate the feasibility of adjuvant chemotherapy with S-1 in patients after esophagectomy. METHODS We investigated the tolerability of a 2-week administration followed by 1-week rest regimen of S1 as postoperative adjuvant therapy in 20 patients with esophageal squamous cell carcinoma who received neoadjuvant chemotherapy (NAC) and 22 patients who did not receive NAC during 2011-2020. RESULTS In the non-NAC group, the mean and median relative dose intensity (RDI) were 78.7% and 99.4%, respectively, and 11 patients (50%) had altered treatment schedules. The corresponding rates in the NAC group were 77.9% and 100%, respectively, and nine patients (45%) had altered treatment schedules, with no significant difference among the groups. Moreover, 17 patients (77.2%) in the non-NAC group and 16 patients (80.0%) in the NAC group continued S-1 treatment as planned for one year postoperatively, with no significant difference in the S-1 continuation rate (p = 0.500). Seventeen of 22 patients (77.3%) and 15 of 20 patients (75.0%) experienced several adverse events in the non-NAC and NAC groups, respectively. The frequency, severity, and type of adverse events were consistent among patients with and without NAC. CONCLUSIONS S-1 could be safely and continuously administered as adjuvant chemotherapy for patients with esophageal cancer regardless of NAC. Long-term prognosis should be evaluated for S-1 to become the standard treatment after esophagectomy.

Abstract
Background: We assessed the relationship between preoperative prognostic nutritional index (PNI) and short- and long-term outcomes among gastric cancer patients because the clinical significance of PNI in these patients remains controversial. Materials and Methods: We retrospectively reviewed the medical records of 434 consecutive patients who underwent curative laparoscopic gastrectomy for gastric cancer. Results: Patients with postoperative complications had a significantly poorer overall survival (OS) than those without. On multivariate analyses, postoperative complications were independently associated with PNI value and operative procedure type. In the low PNI group (n = 118), those with postoperative complications experienced significantly poorer OS than those without complications. Among the low PNI group with pTNM stage I and II disease, those with postoperative complications experienced significantly worse OS than those without complications. However, among the high PNI group and patients with stage II and III disease in the low PNI group, OS was similar with respect to postoperative complications. Conclusions: The present study confirmed that long-term prognosis was unaffected by postoperative complications in well-nourished gastric cancer patients. In addition, preoperative nutritional status and postoperative complications, may be crucial in determining the prognosis of gastric cancer, especially in early-stage cancer.

Abstract
BACKGROUND Although pediatric inguinal hernia (IH) is a very common disease, systematic reviews of herniated organs are scarce. The current study aims to clarify the contents of pediatric IH using preoperative ultrasonography (US) in association with patient age, sex, and risk for developing irreducible/strangulated hernia. METHODS The medical records of pediatric IH patients who underwent inguinal US examination prior to surgery between 2014 and 2019 were reviewed. Hernia contents were categorized into four groups based on US findings: bowel, omentum, ovary with or without fallopian tube, and ascites. RESULTS A total of 524 IH lesions found in 220 men and 304 women were analyzed. The most common hernia content in patients under 12 months of age was the bowel (91.0%) in males and ovaries (89.5%) in females. The omentum became the most common herniated organ in both men (78.6%) and women (88.0%) aged 2 years and older. Emergency operations were performed in 3 patients (0.57%) due to irreducible IH, where 2 patients with irreducible ovaries, 5 and 7 months old, developed ovarian torsion and needed to undergo emergent salpingo-oophorectomy. CONCLUSIONS The contents of pediatric IH depended on patient age and sex. Herniated ovaries in infants can twist in the hernia sac and become strangulated. It is important for clinicians to expect the herniated organ and take appropriate measures in the pediatric primary care setting.

Abstract
Introduction The overall incidence of port site hernias in laparoscopy and robot-assisted surgeries ranges from 0% to 5.2%. Sufficient port site closure is essential to reduce and prevent the occurrence of port site hernia. However, complete fascial closure of 8-mm robot-port site appears to be difficult. In this study, we propose a safe and reliable robot-assisted port-site closure for robot-assisted gastrectomy. Materials and methods The robotic arm was tilted 60–70° cranially or caudally to create a small gap between the port and the skin margin that was cut open for port insertion. While viewing through the robotic camera and grasping the polydioxanone (PDS) thread, the Lapa-Her-Closure was inserted into the peritoneal cavity through the gap. The Lapa-Her-Closure was removed after the PDS thread was grasped with robotic forceps. Subsequently, the Lapa-Her-Closure was inserted into the abdominal cavity by tilting the arm cranially or caudally, in contrast to the previous step. The PDS thread was inserted into the loop wire using robotic forceps. After tightening the loop wire and grasping the PDS thread, the Lapa-Her-Closure was removed, and the PDS thread was ligated to complete the abdominal wall closure, with total closure of the fascia and peritoneum. Results and conclusions We utilized this port site closure technique in 12 patients who underwent robot-assisted gastrectomy for gastric cancer. The procedure was accomplished safely and efficiently in all cases without any technical problems. In conclusion, our port site closure is safe, reliable, and efficient procedure that can be performed using basic surgical techniques. This study discusses a new approach in robot-assisted port site closure for robot-assisted gastrectomy. •Our study makes a significant contribution to the literature because it introduces a safe, reliable, and efficient approach of robot-assisted port site closure for robot-assisted gastrectomy to reduce the occurrence of hernias.

Abstract
BACKGROUND Risk factors for anastomotic leakage include local factors such as excessive tension across anastomosis and increased intraluminal pressure on the gastric conduit; therefore, we consider the placement of a nasogastric tube to be essential in reducing anastomotic leakage. In this study, we devised a safe and simple technique to place an NGT during an end-to-side, automatic circular-stapled esophagogastrostomy. METHODS First, a 4-0 nylon thread is fixed in the narrow groove between the plastic and metal parts of the tip of the anvil head. After dissecting the esophagus, the tip of the NGT is guided out of the lumen of the cervical esophageal stump. The connecting nylon thread is applied to the anvil head with the tip of the NGT. The anvil head is inserted into the cervical esophageal stump, and a purse-string suture is performed on the esophageal stump to complete the anvil head placement. The main unit of the automated stapler is inserted through the tip of a reconstructed gastric conduit, and the stapler is subsequently fired and an end-to-side esophagogastrostomy is achieved. The main unit of the automated stapler is then pulled out from the gastric conduit, and the NGT comes out with the anvil head from the tip of the reconstructed gastric conduit. Subsequently, the nylon thread is cut. After creating an α-loop with the NGT outside of the lumen, the tip of the NGT is inserted into the gastric conduit along the lesser curvature toward the caudal side. Finally, the inlet of the automated stapler on the tip of the gastric conduit is closed with an automated linear stapler, and the esophagogastrostomy is completed. RESULTS We utilized this technique in seven patients who underwent esophagectomy for esophageal cancer; smooth and safe placement of the NGT was accomplished in all cases. CONCLUSION Our technique of NGT placement is simple, safe, and feasible.

Abstract
Gastrointestinal stromal tumors (GISTs) develop in the digestive tract, mainly in the stomach, small intestine, colon, or esophagus. However, primary tumors with the same pathologic features as GISTs have been reported to occur outside of the digestive tract and are called extragastrointestinal stromal tumor (EGIST). We herein report a rare case of EGIST arising from the greater omentum in a patient with abdominal pain caused by intraperitoneal bleeding from the tumor.

Abstract
Pyomyositis has recently been recognized as a primary infection of the large skeletal muscles, and it is often accompanied by single or multiple intramuscular abscess formation. Immunocompromised patients, including those with diabetes mellitus, human immunodeficiency virus infection, and cancer, as well as those undergoing chemotherapy, are at a greater risk of developing pyomyositis. A 78-year-old Japanese man with recurrent gastric cancer being treated with chemotherapy presented with sudden-onset pain in his left lower extremity while undergoing a second-line regimen with irinotecan. T2-weighted magnetic resonance imaging (MRI) showed an abnormally high-intensity signal in the left internal and external obturator muscles, a finding consistent with pyomyositis. Following intensive antibiotic treatment, the patient recovered completely and was able to resume chemotherapy with irinotecan. For a patient who developed pyomyositis during chemotherapy for gastric cancer, early diagnosis using MRI followed by administration of timely intensive antibiotic therapy resulted in complete recovery.

Abstract
BACKGROUND This study aimed to evaluate the feasibility, safety, and efficacy of postoperative adjuvant chemotherapy with docetaxel/cisplatin/S-1 (DCS) following S-1 therapy in patients with stage III gastric cancer after curative gastrectomy. METHODS Patients with stage III gastric cancer who underwent D2 gastrectomy were enrolled. Adjuvant chemotherapy was initiated within 8 weeks of gastrectomy. The first cycle of chemotherapy consisted of S-1 monotherapy (day 1-14), followed by a 7-day rest period. Cycles 2 and 3 consisted of the following: S-1 (day 1-14) administration, followed by a 14-day rest period, and an intravenous infusion of cisplatin and docetaxel on days 1 and 15. After two cycles, S-1 was administered for up to 1 year. RESULTS Thirty patients were enrolled between 2014 and 2017. Febrile neutropenia of grade 3 or higher was the most common hematological toxicity with 4 patients (13.3%). Other hematological toxicities of grade 3 or higher were as follows: neutropenia in 3 (10.0%), leukopenia in 3 (10.0%), and anemia in 2 (6.7%) patients. Most frequent non-hematological toxicity of grade 3 was anorexia (n = 4, 13.3%) and general fatigue (n = 3, 10.0%); no grade 4 non-hematological toxicities were observed. Twenty-five patients (83.3%) completed two cycles of DCS treatment and 18 (60.0%) completed subsequent S-1 treatment for 1 year. The relative dose intensity of docetaxel and cisplatin was 0.86 and that of S-1 was 0.88. CONCLUSION The DCS regimen can be acceptable as an adjuvant chemotherapy and offers an effective postoperative treatment option for stage III gastric cancer patients.

Abstract
PURPOSE The purpose of this study was to evaluate the optimum volume embolization ratio (VER) for the prevention of recanalization after portal vein embolization (PVE) and the influence of recanalization on future liver remnant (FLR) function using technetium-99m galactosyl human serum albumin single-photon emission computed tomography (99mTc-GSA SPECT/CT) fusion imaging. METHODS We analyzed procedural data of 18 patients who underwent PVE from 2015 to 2018. A total of 29 portal branches were embolized (12 anterior branch, 11 posterior branch, 4 left branch, 2 right branch) with absolute ethanol and coils. Portal vein recanalization was evaluated three weeks after PVE by contrast-enhanced CT. We classified the treated portal branches as non-recanalized and recanalized. VER was compared between the groups. In addition, for each patient, we calculated and evaluated the ratio of FLR volume to total liver volume (volumetric %FLR), FLR count to total liver count on 99mTc-GSA SPECT/CT fusion imaging (functional %FLR), and functional-volumetric ratio (functional %FLR/ volumetric %FLR). RESULTS Twenty-six portal branches showed no recanalization (non-recanalized group, n=26, 89.7%), while three portal branches showed recanalization (recanalized group, n=3, 10.3%). The median VER was 4.94% (3.12%-11.1%) in the non-recanalized group and 3.49% (2.76%-4.32%) in the recanalized group, which was significantly different between the groups (p = 0.045, Mann-Whitney U test). The median functional-volumetric ratio was 1.16 (1.03-1.50) in non-recanalized patients (n=15, 83.3%) and 1.01 (0.96-1.13) in recanalized patients (n=3, 16.7%), and it was significantly higher in the non-recanalized patients (p = 0.021, Mann-Whitney U test). CONCLUSION The VER for preventing recanalization after PVE was approximately 5% (> 4.94%). 99mTc-GSA SPECT/CT fusion imaging revealed a decrease in FLR function due to recanalization after PVE.

Abstract
The rare decay K_{L}→π^{0}νν[over ¯] was studied with the dataset taken at the J-PARC KOTO experiment in 2016, 2017, and 2018. With a single event sensitivity of (7.20±0.05_{stat}±0.66_{syst})×10^{-10}, three candidate events were observed in the signal region. After unveiling them, contaminations from K^{±} and scattered K_{L} decays were studied, and the total number of background events was estimated to be 1.22±0.26. We conclude that the number of observed events is statistically consistent with the background expectation. For this dataset, we set an upper limit of 4.9×10^{-9} on the branching fraction of K_{L}→π^{0}νν[over ¯] at the 90% confidence level.

Abstract
BACKGROUND The role of ligation of the portal venous branches to the caudate lobe (cPVL) as preparation for planned major hepatectomy is unclear. The aim of this study was to evaluate the efficacy of laparoscopic cPVL (Lap-cPVL) concomitant with transileocolic portal vein embolization of the right portal venous system (rTIPE), namely, Lap-cPVL/rTIPE, for planned right hemihepatectomy (rHx) in advanced hepatobiliary cancer patients. METHODS Thirty-one patients who underwent rHx after rTIPE with/without Lap-cPVL between March 2013 and March 2020 were enrolled in this study. The Lap-cPVL was performed for the portal branches of the right caudate lobe. RESULTS Eight of the 31 patients underwent Lap-cPVL/rTIPE. The degree of hypertrophy was significantly increased in Lap-cPVL/rTIPE (19.3%, range 6.5-25.6%) as compared to rTIPE (7.2%, range - 1.1 to 21.2%) (p=0.027). The functional kinetic growth rate was also significantly increased in Lap-cPVL/rTIPE (5.40%, range 2.17-5.97) than that in rTIPE (1.85%, range - 0.22 to 6.45%) (p=0.046). Postoperative liver failure ≧ grade B occurred in 21.7% of patients in rTIPE, while there was no postoperative liver failure ≧ grade B in Lap-cPVL/rTIPE. Mortality rates were zero after rHx in this study. CONCLUSIONS Lap-cPVL/rTIPE is safe and provides an additional effect on liver hypertrophy in advanced hepatobiliary cancers.

Abstract
BACKGROUND Rectal prolapse in young women is rare. Although laparoscopic ventral mesh rectopexy is the standard procedure because of its lower recurrence rate, postoperative infertility is a concern. Perineal rectosigmoidectomy (Altemeier procedure) is useful for these patients. However, the risk of anastomotic leakage should be considered. Recently, the usefulness of fluorescence imaging with indocyanine green (ICG) to prevent anastomotic leakage was reported. We report a case of an adolescent woman with complete rectal prolapse who underwent ICG fluorescence imaging-assisted Altemeier rectosigmoidectomy.
CASE SUMMARY A 17-year-old woman who had a mental disorder was admitted to our hospital for treatment for water intoxication. The patient also suffered from rectal prolapse, approximately 3 mo before admission. She was referred to our surgical department because recurrent rectal prolapse could worsen her psychiatric disorder. Approximately 10 cm of complete rectal prolapse was observed. However, the mean maximum anal resting and constriction pressures were within normal limits on anorectal manometry. Because she had the desire to bear children in the future, she underwent Altemeier perineal rectosigmoidectomy to prevent surgery-related infertility. We performed ICG fluorescence imaging at the same time as surgery to reduce the risk of anastomotic leakage. Her postoperative course was uneventful, and the rectal prolapse was completely resolved. She continued to do well 18 mo after surgery, without recurrence of the rectal prolapse.
CONCLUSION ICG fluorescence imaging-assisted Altemeier perineal rectosigmoidectomy is useful in preventing postoperative anastomotic leakage in young as well as elderly patients.

Abstract
BACKGROUND/PURPOSE Few reports have evaluated the differences in the predictive accuracy between the physiological and operative severity score for the enumeration of mortality and morbidity (POSSUM) and estimation of physiologic ability and surgical stress (E-PASS) in pancreatic surgery. Thus, we evaluated the accuracy and similarity of POSSUM and E-PASS for the prediction of severe postoperative complications (PCs) after pancreatic surgery. METHODS We enrolled 343 consecutive patients who underwent pancreatic surgery in our department between April 2006 and September 2017. The difference in predictive values of POSSUM and E-PASS for the occurrence of PCs ≥ Clavien-Dindo grade IIIa (PCs-CD ≥ IIIa) was nonparametrically compared. The predictive accuracy and similarity of each tool was examined using the receiver operating characteristic (ROC) curve and linear regression analyses. RESULTS Forty-five patients developed PCs-CD ≥ IIIa. E-PASS had a significantly higher predictive value for estimating PCs-CD ≥ IIIa occurrence (P = .002) than did POSSUM. The area under the curve value in ROC analysis was significantly higher in E-PASS than in POSSUM (0.643 vs 0.543, P = .014), with a weak positive correlation in the predictive value between E-PASS and POSSUM (R2 = .333, P < .001). CONCLUSION Estimation of physiologic ability and surgical stress was useful for predicting severe PCs after pancreatic surgery and had a higher accuracy than POSSUM.

Abstract
BACKGROUND Portal vein embolization (PVE) is widely used to promote the hypertrophy of a future liver remnant (FLR) and reduce posthepatectomy liver failure. The aim of this study was to evaluate the efficacy of transileocecal portal embolization (TIPE) associated with staging laparoscopy (hybrid lap-TIPE) for a planned hepatectomy in advanced hepatobiliary cancers. METHODS The hybrid lap-TIPE procedure consisted of staging laparoscopy for complete screening of the abdominal cavity with cytoreductive surgery and subsequent TIPE. Data on hybrid lap-TIPE, performed between March 2013 and February 2020, were collected retrospectively. RESULTS Hybrid lap-TIPE was conducted for 52 patients, and a subsequent TIPE was accomplished in 42 patients (80.8%), since staging laparoscopy detected latent or unresectable factors in 13 patients (25.0%), among which 2 patients with hepatocellular carcinoma and 1 with colorectal liver metastasis received laparoscopic cytoreductive surgery for latent lesions in the FLR. Finally, radical hepatectomy was completed in 36 patients (69.2%), including 3 patients who underwent cytoreductive surgery. The most common operation was an extended right hepatectomy (50.0%), followed by right hepatectomy (30.6%), including 3 hepatopancreatoduodenectomies. The overall morbidity associated with hybrid lap-TIPE and hepatectomy was 7.1% and 41.7%, respectively. The mortality associated with hybrid lap-TIPE and hepatectomy was 0% and 5.6%, respectively. The rates of 2-year survival and 2-year disease-free survival were 64.8% and 61.9%, respectively, after hepatectomy. CONCLUSIONS Hybrid lap-TIPE is safe and could be a useful treatment option for patients with advanced hepatobiliary cancer because it can help to identify optimal candidates for PVE followed by a planned hepatectomy.

Abstract
Background: Inflammation influences cancer progression by increasing catabolism and impairing nutrient absorption. We compared the prognostic ability of three inflammation-based prognostic scoring systems—the Glasgow prognostic score (GPS), modified GPS (mGPS), and high-sensitivity mGPS (HS-mGPS)—in gastric cancer patients. Materials and Methods: We retrospectively examined 434 curatively resected gastric cancer patients to evaluate the prognostic ability of scoring systems for overall survival (OS) and cancer-specific survival (CSS). Results: OS analysis identified the following independent prognostic factors: GPS model: pathological stage (pStage, p < 0.001), carcinoembryonic antigen (CEA, p = 0.004), and GPS 1 (hazard ratio [HR], 1.929; 95% confidence interval [CI], 1.152-3.228; p = 0.013); mGPS model: body mass index (BMI, p = 0.027), pStage (p < 0.001), and CEA (p < 0.001); HS-mGPS model: BMI (p = 0.029), pStage (p < 0.001), and CEA (p = 0.003). mGPS and HS-mGPS were not independent prognostic factors for OS. CSS analysis of the GPS model identified pStage (p < 0.001), CEA (p = 0.015), and GPS 1 (HR; 2.095, 95% CI; 1.025–4.283; p = 0.043) and 2 (HR, 2.812; 95% CI, 1.111–7.116; p = 0.029) as independent prognostic factors; however, mGPS and HS-mGPS were not independent prognostic factors for CSS. Log-rank tests demonstrated significant differences in OS among patients with GPS 0 vs. 1 (p < 0.001) and 0 vs. 2 (p < 0.001) and in CSS among the three GPS (0 vs. 1; p = 0.005, 0 vs. 2; p < 0.001, 1 vs. 2; p = 0.009). Conclusions: GPS most reliably predicts long-term survival of gastric cancer patients.

Abstract
Case of esophageal cancer associated with an aberrant V2. Used preoperative 3D-CT for performing safe VATS-E. Preoperative contrast-enhanced 3D-CT clearly depicted the aberrant V2.
Background Subcarinal lymphadenectomy is an essential procedure in curative esophagectomy for esophageal cancer. The right superior pulmonary vein (RSPV) and its branches are usually located in front of the right main or intermediate bronchus. However, an anomalous posterior branch (aberrant V2) of RSPV passes behind the right intermediate bronchus, where the aberrant V2 may be embedded in the subcarinal nodal packet. This can lead to unanticipated bleeding when dissecting the subcarinal lymph node. We present a case study on the use of preoperative three-dimensional contrast-enhanced computed tomography (3D-CT) for performing a safe video-assisted thoracoscopic surgery-esophagectomy in lower thoracic esophageal cancer. Case presentation A 77-year-old man had esophageal cancer associated with an aberrant V2 passing behind the right intermediate bronchus. Esophagogastroduodenoscopy revealed a type 1 tumor in the lower thoracic esophagus. Contrast-enhanced and 3D-CT scans showed a space-occupying lesion with contrast enhancement and an aberrant V2 passing behind the right intermediate bronchus, respectively. The patient was then diagnosed with lower thoracic esophageal cancer (cT2cN1cM0 cStage II). As per the patient’s request, he underwent a surgery-first approach followed by adjuvant chemotherapy. The patient underwent video-assisted thoracoscopic surgery-esophagectomy (VATS-E) with three-field lymphadenectomy, and a large aberrant V2 involving the subcarinal nodal packet was recognized behind the right intermediate bronchus. After the thoracoscopic subtotal esophagectomy with three-field lymph node dissection, laparoscopy-assisted reconstruction of the esophagus was performed with elevation of the gastric conduit to the neck. Recurrent laryngeal nerve palsy was not observed. He started to receive rehabilitation for swallowing on day 3 and resumed oral intake on day 10 after surgery. The final pathological diagnosis was squamous cell carcinoma of the esophagus (pT3N1M0 pStageIII). Conclusions Preoperative contrast-enhanced 3D-CT clearly depicted the aberrant V2, which enabled us to perform a safe VATS-E with three-field lymphadenectomy. Thorough understanding of the anatomical configuration of the pulmonary vessels and bronchus is important for avoiding unexpected bleeding during subcarinal lymphadenectomy. 3D-CT imaging study is useful for recognizing the anomalous RSPV before surgery.

Abstract
Aside from the induction of cell death, some anticancer chemotherapeutic drugs can modulate antitumor immune responses. In this study, we examined the anticancer effects of 5‐fluorouracil (5‐FU) and oxaliplatin (L‐OHP), which are standard chemotherapeutic drugs for colon cancer, combined with cyclophosphamide (CP) in two mouse colon cancer models (CT26 and MC38 colon adenocarcinoma models). In the CT26 model, two injections of 5‐FU/L‐OHP and CP significantly suppressed the growth of subcutaneously established CT26 tumors compared with either 5‐FU/L‐OHP or CP, without a significant loss of body weight. The anticancer effect was weakened in nude mice. Cured mice acquired protective immunity against CT26, and CT26‐specific cytotoxic T cells (CTLs) were induced from their spleen cells. Analysis of tumor‐infiltrating immune cells revealed that 5‐FU/L‐OHP treatment with or without CP increased the proportion of CD8+ T cells at tumor sites. The 5‐FU/L‐OHP treatment decreased the proportion of granulocytic myeloid‐derived suppressor cells (MDSCs) and increased monocytic MDSCs in tumor sites, whereas the addition of CP treatment reversed these changes. In the MC38 model, although significant anticancer effects of the triple combination therapy were seen, additional treatment with anti‐PD‐1 antibody increased the number of cured mice. These mice exhibited protective immunity against MC38, and MC38‐specific CTLs were generated from their spleen cells. Together, these results indicate that the antitumor effects of the combination of 5‐FU/L‐OHP and CP mainly depend on host T cells; moreover, the therapeutic efficacy can be effectively boosted by immune checkpoint blockade.

Abstract
The geriatric nutritional risk index (GNRI) is associated with mortality in several malignancies. We retrospectively analyzed whether the GNRI can predict long-term outcomes in 191 patients with esophageal squamous cell carcinoma (ESCC) after curative esophagectomies by evaluating their cancer-specific survival (CSS). In multivariate analyses, serum albumin (hazard ratio [HR], 2.498; p = 0.0043), GNRI (HR, 1.941; p = 0.0181), pathological tumor-node-metastasis (pTNM) stage (HR, 3.884; p < 0.0001), and tumor differentiation (HR, 2.307; p = 0.0066) were independent prognostic factors for CSS. In pTNM stage I, multivariate analysis identified C-reactive protein (HR, 7.172; p = 0.0483) and GNRI (HR, 5.579; p = 0.0291) as independent prognostic factors for CSS. In univariate analyses in pTNM stages II and III, only low GNRI (p = 0.0095) and low serum albumin levels (p = 0.0119), respectively, were significantly associated with worse CSS. In patients with low GNRI, CSS was significantly worse than in those with normal GNRI (p = 0.0011), especially in pTNM stages I (p = 0.0044) and II (p = 0.0036) groups, but not in stage III group (p = 0.5099). Preoperative GNRI may sort patients into low- or high-risk groups for shorter CSS, especially in those with pTNM stage I and II ESCC.

Abstract
Background: Systemic immune-inflammation index (SII)—comprising platelet, neutrophil, and lymphocyte count—is an objective and reliable biomarker for predicting the prognosis in cancer patients because it comprehensively reflects the balance between host inflammatory and immune responses. In this study, we clarified the prognostic impact of immunoinflammation-based indices, i. e. SII, neutrophil/lymphocyte ratio (NLR), and platelet/lymphocyte ratio (PLR), in gastric cancer patients.
Results: In multivariate analysis, the American Society of Anesthesiologists physical status (ASA-PS) (hazard ratio [HR]: 3.366, p < 0.001), tumor differentiation (HR: 1.705, p = 0.020), pathological Tumor, Node, Metastasis (pTNM) stage (HR: 2.160, p = 0.008), and carcinoembryonic antigen (CEA) (HR: 1.964, p = 0.003) were independent prognostic factors for OS in all patients. Further, multivariate analysis revealed that age (HR: 2.088, p = 0.040), ASA-PS (HR: 2.339, p = 0.043), tumor differentiation (HR: 1.748, p = 0.044), and pTNM stage (HR: 2.114, p = 0.024) were independent prognostic factors for OS among patients without inflammation; SII was not a prognostic factor for OS. Meanwhile, body mass index (HR: 5.055, p = 0.011), ASA-PS (HR: 3.403, p = 0.007), and SII (HR: 4.208, p = 0.026) were independent prognostic factors for OS among patients with inflammation.
Materials and Methods: We performed a retrospective review of 412 patients who underwent curative laparoscopic gastrectomy. The prognostic value of SII was compared between a low SII group (SII<661.9) and high SII group (SII≥661.9). We analyzed the predictive ability of immunoinflammation-based indices for overall survival (OS) based on a C-reactive protein (CRP) level of 0.5.
Conclusions: Compared to NLR and PLR, SII is the most significant prognostic biomarker for OS, especially in gastric cancer patients with inflammation.

Abstract
Persistent gastric mucosal damage caused by Helicobacter pylori infection is a major risk factor for gastric cancer (GC). The Epstein-Barr virus (EBV) is also associated with GC. Most patients with EBV-associated GC are infected with H. pylori in East Asia. However, very few reports have described where and when both H. pylori and EBV infect the gastric mucosa. To clarify this, old biopsy samples used for the rapid urease test (RUT) were applied to count EBV genomic DNA (gDNA) copies using DNA probe quantitative polymerase chain reaction. DNA extracted from the gastric biopsy samples of 58 patients with atrophic gastritis was used to analyze the correlation between the degree of atrophic gastritis and the copy number of EBV gDNA. EBV was detected in 44 cases (75.9%), with viral copy numbers ranging from 12.6 to 4754.6. A significant correlation was found between patients with more than 900 copies of EBV gDNA and those with a more severe grade of atrophic gastritis (p = 0.041). This study shows that EBV can be detected in RUT samples in a manner that reduces patient burden.

Abstract
Background: The geriatric nutritional risk index (GNRI) was developed to evaluate the prognosis in elderly hospitalized patients at risk of malnutrition and related morbidity and mortality. This study aimed to evaluate the relationship between preoperative GNRI and long-term outcomes in elderly gastric cancer patients. Materials and Methods: We retrospectively reviewed 297 consecutive patients aged ≥ 65 years who underwent laparoscopic gastrectomy with R0 resection and evaluated their overall survival (OS) and cancer-specific survival (CSS). Results: In the univariate analyses, OS was significantly associated with the American Society of Anesthesiologists Physical Status (ASA-PS), tumor size, tumor differentiation, pathological stage, carcinoembryonic antigen (CEA), C-reactive protein, postoperative complications, and GNRI, whereas in the univariate analyses of CSS, ASA-PS, tumor size, tumor differentiation, pathological stage, CEA, postoperative adjuvant chemotherapy, and GNRI were significantly associated with poor prognosis. In the multivariate analysis, ASA-PS, tumor differentiation, pathological stage, and GNRI were significant independent prognostic factors of OS, whereas ASA-PS, pathological stage, and CEA were significant independent prognostic factors of CSS. Conclusions: GNRI is significantly associated with OS and CSS in elderly gastric cancer patients and is an independent predictor of OS. It is a simple, cost-effective, and promising nutritional index for predicting OS in elderly patients.

BACKGROUND An artery-first approach for pancreatic cancer (PC) is challenging to perform laparoscopically and is mainly performed using an open approach. The aims of this study were to assess the safety and feasibility of laparoscopic radical antegrade modular pancreatosplenectomy (RAMPS) with an artery-first approach (L-aRAMPS) as compared with open aRAMPS (O-aRAMPS) in resectable PC using matched-pair analysis. METHODS Artery-first approach is an early dissection of the superior mesenteric artery (SMA) from behind the pancreas body as the first surgical step. Data on L-aRAMPS and O-aRAMPS, performed between July 2013 and November 2019, were collected retrospectively. Additionally, the spatial characteristics of the splenic artery were analyzed using computed tomography. RESULTS Thirty L-aRAMPS and 33 O-aRAMPS for resectable PC were included. After matching, 15 L-aRAMPS were compared with 15 O-aRAMPS. Median intraoperative blood loss and hospital stay were significantly improved in L-aRAMPS compared to O-aRAMPS (30 vs. 220 g, p < 0.001; 12 vs. 16 days, p = 0.049). The overall morbidity was similar in both study groups. The total number of lymph nodes dissected and those harvested from around the SMA and R0 resection was similar in both study groups. We classified the width of the cross section of the pancreas body into three equal parts: the upper, middle, and lower parts of the pancreas; 63% of the splenic artery origin was located in middle and lower parts of the pancreas body. CONCLUSION L-aRAMPS is technically safe and oncologically feasible to secure favorable surgical outcomes for resectable PC patients.

Abstract
INTRODUCTION The foreign body reaction caused by oil contrast medium, Lipiodol, is rare. We present a rare case of inflammatory granuloma in the inguinal hernia sac after hysterosalpingography with lipiodol. PRESENTATION OF CASE A 30-year-old woman who had left inguinal growing mass for 7 months after hysterosalpingography with Lipiodol for examination of infertile. About 3 cm soft mass was palpable on the left inguinal region, and plane CT scan showed a multifocal cystic mass with metal concentration. Thus, laparoscopic herniorrhaphy was performed to repair the inguinal hernia and to confirm the contents of cystic lesion. The hernia sac filled with mucinous contents. Pathological examination revealed that inflammatory granuloma due to numerous lipid droplets and phagocytic images of leukocytes in the hernia capsule. DISCUSSION AND CONCLUSION Although oil contrast medium is safety agent, there is rear complication which need the surgical treatment. Complete resection of granuloma, including hernia sac, is important to prevent recurrence.

Abstract
Foreign body granuloma due to retained surgical sponge (gossypiboma) with penetration into the small intestine is very rare. Cases of gossypiboma in the abdominal cavity have sometimes been reported, yet the correct incidence has not been determined, only estimated to occur in one of every 1,000 to 1,500 intra-abdominal operations. Acute abdomen may be observed in some cases, requiring treatment. We herein introduce the case of a 70-year-old woman with gossypiboma penetrating into the small intestine presented with anemia and hematochezia. She had a history of emergency laparotomy for ectopic pregnancy several decades ago. A dynamic contrast-enhanced computed tomography revealed a hypovascular mass containing air bubbles that continued to the small intestine approximately 50 mm in size in the right lower abdomen. In addition to describing the presentation and outcome of our patient, we review the image findings of gossypiboma.

Abstract
A 70-year-old woman with loss of appetite was referred to our hospital for further examinations. Computed tomography revealed a low density tumor in the body of the pancreas measuring 4 cm in diameter. The main pancreatic duct was dilated on both the head and caudal side of the tumor. Magnetic resonance imaging showed the mass as a low intensity area in T1-weighted and high intensity area in T2-weighted images. Endoscopic retrograde cholangiopancreatography findings indicated that the main pancreatic duct was continuous with the lumen of the tumor. A cytological examination of pancreatic juice showed a class IV tumor. A distal pancreatectomy was performed as a curative resection procedure. The findings of hematoxylin eosin staining and mucus trait led to a diagnosis of invasive cancer derived from an intraductal papillary mucinous neoplasm (IPMN). We also performed sequencing analysis to investigate GNAS and K-RAS mutations in the tumor, though neither the GNAS mutation c602G>A nor K-RAS mutation c35G>A were observed. Cases negative for a GNAS mutation can be considered to have an increased risk of invasive cancer derived from an IPMN.

Abstract
An estuary is a dynamic environment where marine and fluvial processes meet to form complex and transient morphology. The estuary morphology is largely determined by net sediment transport by two-way tidal flows, but the hydrodynamics also depends on the morphology of the tidal channels. The estuary inherently accommodates cyclic processes that are internally generated through hydro-morphodynamic interactions. In addition, the estuary evolves in response to changes in external forces by natural and anthropogenic factors. Morphological changes under the different controls often hinder the comprehension of the evolutionary processes of estuaries. Here we explored morphological changes in the Sittang River estuary, Myanmar, which has great morphological dynamism from extreme tidal energy and large sediment inputs, through field surveys and satellite imagery analysis. We identify an autocyclic process in a sedimentary system driving large-scale channel migration in decadal to multidecadal cycles. We show that drastic changes of the estuary morphology occasionally occur with rapid bank erosion through modulation of the cyclic channel migration under conflicting tidal and fluvial forces. This extreme case with minimal human intervention highlights channel migration as a key process in morphological evolution of tide-dominated estuaries undergoing active infilling.

Abstract
BACKGROUND/AIM The aim of the current study was to investigate the impact of the preoperative red cell distribution width (RDW) value on the overall survival (OS) and cancer-specific survival (CSS) of gastric cancer patients. PATIENTS AND METHODS A total of 366 gastric cancer patients who underwent curative gastrectomy were retrospectively reviewed. Among them, RDW was evaluated in 165 non-elderly and 201 elderly patients. RESULTS Multivariate analysis revealed that pathological stage (pStage), RDW, and carcinoembryonic antigen (CEA), were independent prognostic factors of OS, while pStage and RDW were independent prognostic factors of CSS. In non-elderly patients, based on the multivariate analysis, pStage, adjuvant chemotherapy, and RDW were identified as independent prognostic factors of OS. In elderly patients, RDW was identified as independent prognostic factors of OS and CSS. CONCLUSION Preoperative RDW is a promising independent prognostic factor in gastric cancer.

Abstract
411 Background: FOLFIRINOX (FFX) is a standard therapy for unresectable/recurrent pancreatic cancer, but it is associated with a high frequency of severe adverse events, especially blood toxicity. Human pegylated granulocyte colony-stimulating factor (PEG-G-CSF) can reduce the outpatient frequency during outpatient chemotherapy. However, there are few reports on the effectiveness of PEG-G-CSF in preventing febrile neutropenia during FFX. We retrospectively investigated the usefulness of PEG-G-CSF in reducing the incidence of FN during FFX. Methods: From June 2014 to January 2017, 40 patients with unresectable pancreatic cancer received FFX (including modified FFX) at our hospital. Twenty-three patients were administered PEG-G-CSF as primary/secondary preventive therapy (G group) and 17 were not administered any G-CSF (NG group). Results: The median patient ages in the G and NG groups were 65 (range, 48-78) and 63 (range, 42-81) years, respectively, and the male to female ratios were 13:10 and 11:6, respectively. There were 13 and 10 patients, respectively, in the G group with performance statuses of 0 and 1 and 8 and 9 such patients, respectively, in the NG group. Seventeen and five patients in the G and NG groups, respectively, had metastatic disease and six and two patients, respectively, had locally advanced disease. The respective response rates (RRs) in the G and NG groups were 30% and 6% (p = 0.0608), and the respective disease control rates (DCRs) were 30% and 41% (p = 0.0407). The median progression-free survivals in the G and NG groups were 7.3 (95% confidence interval [CI], 3–9.4) and 4.5 (95% CI, 1.9–8.5) months, respectively (p = 0.173), and the respective overall survivals were 16.9 (95% CI, 10.2–NA) and 14.2 (95% CI, 7.8–20.5) months (p = 0.302). Conclusions: The DCR was significantly greater in the G group than in the NG group, and the RR tended to be greater in the G group than in the NG group. A high tumor shrinking effect of FFX with PEG-G-CSF indicated that it might be useful as a neoadjuvant chemotherapy. A prospective study is needed to examine first-line chemotherapy in unresectable/recurrent pancreatic cancer and neoadjuvant chemotherapy in borderline/locally advanced pancreatic cancer.
