    The aim of this study was to examine the relationship between reactive swelling of regional lymph node (LN) and survival in colorectal carcinoma. We retrospectively studied 170 patients with surgically resected colorectal carcinoma histopathologically diagnosed as stage II (pStage II). These patients were classified into two groups:a) a "reactive LN swelling" group (clinically diagnosed as positive for LN metastasis, but pathologically negative) and b) a "no LN swelling" group. Survival analyses of the two groups showed that overall survival (OS) and disease-specific survival (DSS) were longer in the reactive LN swelling group than in the no LN swelling group in patients with total colorectal and right-sided colon cancer. Multivariate analyses revealed that reactive LN swelling was an independent prognostic factor in OS and DSS in patients with right-sided colon cancer. Reactive swelling of regional LN is regarded as an expression of local immune responses, which could explain the present results.

    Backgrounds and Aims:Peripherally inserted central catheters (PICC) have been widely used as a blood access route for total parenteral nutrition (TPN) in recent years. However, there have been few reports that evaluated the usefulness of PICC for patients with inflammatory bowel disease (IBD). In this study, we compared the clinical courses in patients with IBD who received TPN during their hospitalization by conventional central venous catheters (CVC) and PICC. Patients and Methods:A total of 137 IBD patients were enrolled. The CVC group and the PICC group included 56 and 81 patients, respectively. The clinical courses in both groups were compared retrospectively. Results:As a complication of the puncture, pneumothorax occurred in two patients (3.6%) in the CVC group, but in none (0%) in the PICC group. The PICC group had significantly higher rates of achieving the scheduled TPN without removing the catheter, lower rates of catheter-related blood stream infection (CRBSI) and longer periods without CRBSI than the CVC group. Conclusion:PICC might be more useful than CVC in terms of safety and the ability to deliver scheduled TPN for IBD patients.

    Laparoscopic cholecystectomy (LC) is performed for gallbladder stones and cholecystitis in a large number of elderly patients. However, the safety of LC in the elderly is questioned. The aim of this study was to investigate predictive factors for the incidence of postoperative complications and deaths after LC in patients aged 80 years and older. Data from 85 elderly patients who underwent LC between January 2005 and December 2015 were prospectively collected in a database at our hospital. The following factors were compared for the occurrence of postoperative complications and deaths:age, gender, Body Mass Index, laboratory date, severity grade of cholecystitis, comorbidity of choledocholithiasis, conversion to open cholecystectomy, early or delayed LC, amount of time from onset to LC, operative duration, blood loss, and the following scoring systems for predicting risk of surgery:ECOG-PS, ASA, SIRS, CONUT, POSSUM, SAS, E-PASS. The complication rate of LC was 14.1% in this cohort. WBC, CRP, BUN, Cre, Na, PT-INR, severity of cholecystitis, conversion to open cholecystectomy, operative duration, early LC, ASA, SIRS, CONUT, POSSUM (PS, OS, complication rate), SAS, E-PASS (PRS, SSS, CRS) showed significant variability in univariate analysis. A high POSSUM score of complication and moderate or severe cholecystitis were independent risk factors for postoperative complication. Analysis of the ROC showed that the best cut-off point for the POSSUM score of complication was 51.5. LC for gallbladder stones and cholecystitis in elderly is a reliable operation, but the procedure for cases with a high score of the POSSUM for complications, or moderate or severe cholecystitis, may have the risk of postoperative complications in elderly patients.

    This case involved a 76-year-old man. Total colonoscopy was performed as a second examination for colorectal cancer because of positive fecal occult blood results, revealing a neoplasm with ulceration in the sigmoid colon. We suspected type-3 colorectal cancer and performed a biopsy, but the biopsy diagnosis showed only an ulcer with active inflammation. Colonoscopic re-examination in a highly advanced medical institution revealed granulomatous inflammation of the sigmoid colon caused by a fish bone, and the fish bone was removed endoscopically. Granulomatous inflammation of the colon caused by a fish bone is very rare, but sometimes needs to be differentiated from cancer. Endoscopic therapy can also be an option, depending on abdominal findings and the penetration status of the fish bone into the large intestinal wall.

    An 80-year-old man presented to our hospital with complaints of tarry stool and shortness of breath. A blood test confirmed marked anemia. On abdominal contrast-enhanced computed tomography, neither hemorrhagic lesions nor tumorous lesions could be pointed out. Upper gastrointestinal endoscopy revealed multiple erythematous flat elevated lesions, which were about 10mm in diameter, located between the stomach and the horizontal part of the duodenum. Colonoscopy revealed similar lesions throughout the entire colon. Pathological examination of biopsy specimens demonstrated the proliferation of neoplastic cells positive for immunostaining of factor VIII-related antigen, CD31, and CD34. Accordingly, the patient was diagnosed with angiosarcoma of the gastrointestinal tract. Although the patient was transferred to another hospital for chemotherapy, he died shortly after the transfer because of deterioration of his bleeding symptoms. Angiosarcoma is a soft-tissue neoplasm of vascular endothelium origin, accounting for less than 2% of all sarcomas. It usually occurs in the skin of the head and neck and in soft tissues. Angiosarcoma of the gastrointestinal tract is rare and is described only in case reports and small series. These tumors are characterized by an extremely aggressive course, with a high tendency to metastasize, leaving patients with a poor prognosis. When angiosarcoma is found in multiple sites of the gastrointestinal tract, it is sometimes difficult to differentiate between primary and metastatic occurrences. We analyzed reported cases of multifocal angiosarcoma of the digestive tract, of which there are 43 so far. In 24 cases, the angiosarcoma was thought to originate from the gastrointestinal tract (primary angiosarcoma). In 13 cases, angiosarcoma of other organs metastasized to the digestive tract (metastatic angiosarcoma). In the remaining 6 cases, whether the multifocal angiosarcoma of the digestive tract was primary or metastatic was unclear. In the current case, no primary lesion was found outside the gastrointestinal tract. Therefore, he was diagnosed with primary multifocal angiosarcoma.

    A 45-year-old man presented with a 24-mm macrocystic lesion at the pancreatic head, which was detected by computed tomography (CT). During six years of follow-up, CT, MRI, and endosonographic images of the cystic lesion showed that the cystic lesion had enlarged to 42mm, with the appearance of a thick cyst wall. Since a cystic tumor could not be ruled out, surgery was performed. Pathological examination of the resected specimen revealed microcystic-type serous cystadenoma of the pancreas, with the presence of internal bleeding in the cyst and hemorrhage and thick fibrous tissue in the cyst wall. We could observe a serous cystic neoplasm with prismatic form changes on an image obtained during long-term follow-up. Thus, we considered this case to be useful for investigating the natural history of serous cystic neoplasm of the pancreas.
