[Stage â £ Gastric Cancer with Long Term Survival by Conversion Surgery-A Case Report].

A 78-year-old man presenting with a chief complaint of discomfort was found to have advanced gastric cancer invading pancreatic body, and with the metastasis of paraaortic lymph node(No. 16). After 3 courses of the S-1 plus oxaliplatin regimen, CT scan showed the disappearance of invasion to pancreatic body, and the No. 16 lymph node. Then total gastrectomy(D2+No. 19+No. 16a1+No. 16a2), Roux-en-Y reconstruction and cholecystectomy were undergoing. Histological assessment for treatment response showed Grade 1a, and we finally diagnosed gastric cancer: MU, Post, type 2, 30×20 mm, tub1>por1, ypT3, ypN1, ycM0, ypStage ⅡB. The postoperative course was uneventful, and the patient was discharged from the hospital on postoperative day 19. S-1 as adjuvant chemotherapy was performed for 12 months, and no recurrence was recognized for 5 years and 9 months after operation.

[A Case Report of Organ Preservation by Total Neoadjuvant Therapy and Local Excision for Lower Rectal Cancer].

In our department, total neoadjuvant therapy(TNT), which is a combination of preoperative chemotherapy and preoperative chemoradiotherapy(nCRT), has been introduced for the purpose of local and systemic disease control for lower rectal cancer. For patients in whom a clinical complete response(cCR)was obtained by TNT, we avoid the surgery and preserve organs, and follow-up strictly under the informed consent(watch and wait). In addition, for patients with remarkably reduced primary lesions(near cCR)without lymphadenopathy after TNT, the option of omitting total mesorectal excision (TME)and performing organ preservation by local excision can be introduced. Here, we report a case in which near cCR was obtained by TNT and organ preservation was performed by local excision. A 67-year-old man with lower rectal cancer(AV 5 cm, 15 mm, type 2, cT2N0M0, cStage Ⅰ)was referred to our department with a desire to preserve the anus. TNT with nCRT→CAPOX was performed, and near cCR was obtained. After that, full thickness local excision of the residual disease was performed by transanal minimally invasive surgery(TAMIS). The final pathological diagnosis was Rb, 0.7 mm, por2, ypT1a, ypPM0, ypDM0, ypRM0. No recurrence is recognized for 3 years and 10 months after the operation.

Successful management following combined thoracic endovascular aortic repair and minimally invasive esophagectomy for primary aortoesophageal fistula: A case report.

Aortoesophageal fistula (AEF) is a rare but life-threatening pathology. We report a case of a primary AEF that was successfully managed with temporary thoracic endovascular aortic repair (TEVAR) and esophagectomy with video-assisted thoracoscopic surgery. A 73-year-old man was transferred to the emergency department with a complaint of hematemesis. A computed tomography scan identified an AEF due to aortic aneurysm. We placed a stent using TEVAR for the purpose of hemodynamic stasis, and the operation was performed 23 h after admission. Right video-assisted thoracoscopic esophagectomy (VATS-E) was chosen, and a cervical esophagostomy and a feeding gastrostomy tube was constructed. Infection had been effectively controlled postoperatively. Four months after the first operation, we performed esophageal reconstruction. At the 70-month follow-up examination, the patient had no signs of mediastinitis. VATS-E immediately after hemostabilization by TEVAR is useful management for primary AEF.

Clinical feasibility of the preoperative C-reactive protein-albumin-lymphocyte index to predict short- and long-term outcomes of patients with gastric cancer.

BACKGROUND: Gastric cancer (GC) is a major leading cause of cancer-related death worldwide. Systemic inflammation and the nutrition-based score are feasible prognostic markers for malignancies. Emerging evidence has also revealed the C-reactive protein-albumin-lymphocyte (CALLY) index to be a prognostic marker for several cancer types. However, its clinical significance to predict surgical and oncologic outcomes of patients with GC remains unclear. METHODS: We assessed the preoperative CALLY index in 426 patients with GC who received gastrectomy. RESULTS: A low preoperative CALLY index was significantly correlated to all well-established clinicopathologic factors for disease development, including an advanced T stage, the presence of venous invasion, lymphatic vessel invasion, lymph node metastasis, distant metastasis, and an advanced TNM stage. A low preoperative CALLY index was also an independent prognostic factor for overall survival (hazard ratio [HR], 2.64; 95 % CI, 1.66-4.2; P < .0001) and disease-free survival (HR, 1.76; 95 % CI, 1.01-3.05; P = .045). In addition, a low preoperative CALLY index was an independent predictive factor for postoperative surgical site infection (odds ratio, 2.64; 95 % CI, 1.42-4.89; P = .002). CONCLUSION: The preoperative CALLY index is valuable for perioperative and oncologic management of patients with GC.

Clinical implications of C-reactive protein-albumin-lymphocyte (CALLY) index in patients with esophageal cancer.

PURPOSE: The C-reactive protein-albumin-lymphocyte (CALLY) index is a novel inflammatory nutritional biomarker. This study aimed to investigate the potential clinical significance and oncological prognostic role of the preoperative CALLY index in patients with esophageal cancer. METHODS: We analyzed the preoperative CALLY index in 146 patients with esophageal cancer. The CALLY index and clinicopathological variables were analyzed by the Mann-Whitney U test, and associations between the CALLY index and survival outcomes were analyzed by Kaplan-Meier analysis and log-rank tests. Univariate and multivariate analyses of prognostic variables were conducted using Cox proportional hazards regression. RESULTS: A lower preoperative CALLY index was significantly correlated with patient age, advanced T stage, presence of lymph node metastasis, neoadjuvant therapy, lymphatic invasion, and advanced stage classification. The preoperative CALLY index decreased significantly in a stage-dependent manner. Patients with esophageal cancer with a low CALLY index had poorer overall survival, disease-free survival than those with a high CALLY index. Multivariate analysis showed that a low CALLY index was an independent prognostic factor for overall survival, disease-free survival and an independent predictor of postoperative surgical site infection. CONCLUSIONS: Preoperative CALLY index is a useful marker to guide the perioperative and postoperative management of patients with esophageal cancer.

Prediction of Post-Gastrectomy Pancreatic Complications: A Preoperative Imaging Study Based on Computed Tomography.

BACKGROUND: Postoperative pancreas-related complications (PPRCs) are common after laparoscopic gastrectomy (LG) in patients with gastric cancer. We estimated the anatomical location of the pancreas on a computed tomography (CT) image and investigated its impact on the incidence of PPRCs after LG. METHODS: We retrospectively reviewed the preoperative CT images of 203 patients who underwent LG for gastric cancer between January 2010 and December 2017. From these images, we measured the gap between the upper edge of the pancreatic body and the root of the common hepatic artery. We evaluated the potential relationship between PPRCs and the gap between pancreas and common hepatic artery (GPC) status using an analysis based on the median cutoff value and assessed the impact of GPC status on PPRC incidence. We performed univariate and multivariate analyses to identify predictive factors for PPRC. RESULT: Postoperative pancreas-related complications occurred in 11 patients (5.4%). The median of the optimal cutoff GPC value for predicting PPRC was 0 mm; therefore, we classified the GPC status into two groups: GPC plus group and GPC minus group. Univariate analysis revealed that sex (male), C-reactive protein (CRP) > .07 mg/dl, GPC plus, and visceral fat area (VFA) > 99 cm2 were associated with the development of PPRC. Multivariate analysis identified only GPC plus as independent predictor of PPRC (hazard ratio: 4.60 [95% confidence interval 1.11-31.15], P = .034). CONCLUSION: The GPC is a simple and reliable predictor of PPRC after LG. Surgeons should evaluate GPC status on preoperative CT images before proceeding with laparoscopic gastric cancer surgery.

Robot-assisted laparoscopic abdominoperineal resection for anal canal cancer associated with Crohn's disease: A case report.

A 37-year-old man with Crohn's disease (CD) and a history of abdominal surgery was diagnosed with anal canal cancer. Robot-assisted laparoscopic abdominoperineal resection was performed and the patient was discharged without any postoperative complications. Recently, minimally invasive surgery for CD patients has grown in popularity. However, there have been few studies of robotic surgery for CD patients with anal canal cancer. To the best of our knowledge, we present the first report of a patient with CD-associated anal canal cancer who underwent robot-assisted laparoscopic abdominoperineal resection.

Clinical factors associated with in-hospital death in pediatric surgical patients admitted to the neonatal intensive care unit: a 15-year single tertiary center experience.

BACKGROUND/PURPOSE: The purpose of this study was to explore clinical characteristics and primary surgical diagnoses associated with in-hospital death in pediatric surgical patients admitted to the neonatal intensive care unit (NICU) of a tertiary hospital. METHODS: This retrospective study includes all patients admitted to our NICU for pediatric surgical diseases between January 2001 and December 2015. Univariate and multivariate binary logistic regression were performed to assess independent factors associated with in-hospital death. RESULTS: A total of 440 cases were included and 334 (83.5%) patients underwent one or more surgeries. Thirty six patients (8.2%) died while hospitalized in the NICU. The 5 most common surgical diagnoses were intestinal atresia/stenosis, anorectal malformation, congenital diaphragmatic hernia (CDH), esophageal atresia, and urinary system disorder. Necrotizing enterocolitis (NEC) had the highest mortality rate. Using logistic regression, in-hospital death was predicted by extremely low birth weight (ELBW) (odds ratio (OR)=6.594; P=0.006), CDH (OR=13.954; P<0.001), and NEC (OR=8.991; P=0.049). CONCLUSIONS: This study describes CDH, NEC, and ELBW are independent predictive factors associated with in-hospital death of pediatric surgical patients in our NICU. Novel approaches for those conditions are required to improve the survival. TYPE OF STUDY: Prognostic LEVELS OF EVIDENCE: II.

Diagnostic Potential of Cell-Free and Exosomal MicroRNAs in the Identification of Patients with High-Risk Colorectal Adenomas.

BACKGROUND: Although there is a growing interest in developing circulating microRNA (miRNA) as noninvasive diagnostic biomarkers for the detection of high-risk colorectal adenomas and early-stage CRCs, but the comparative diagnostic significance of serum vs. exosomal miRNAs remains unexplored. METHODS: Based upon published literature, we performed an initial discovery step by investigating the expression of a miRNA panel in 20 normal colonic mucosa, 27 adenomas, and 19 CRC tissues. We performed subsequent validation by quantifying expression of candidate miRNAs in total serum and in exosomes from 26 adenoma patients and 47 healthy controls, and evaluated their clinical significance and potential diagnostic value in colorectal adenomas. RESULTS: We observed that the expression of four miRNAs, miR-21, miR-29a, miR-92a, and miR-135b, was significantly higher in colorectal adenomas vs. normal colonic mucosa. During validation, expression of miR-21, miR-29a and miR-92a in serum was significantly higher in adenomas vs. healthy controls, significantly correlated with adenoma size and total adenoma number within the colorectum, and significantly discriminated patients with advanced adenomas. In contrast, although exosomal miR-21 and miR-29a levels in adenoma patients were significantly higher than those of healthy volunteers, only exosomal miR-21 significantly correlated with adenoma size and total adenoma number, and could discriminate patients with high-risk adenomas. CONCLUSION: Compared to exosomal miRNAs, serum levels of miR-21, miR-29a and miR-92a are superior diagnostic biomarkers in patients with high-risk adenomatous polyps.

Distinguishing between limited systemic scleroderma-associated pseudo-obstruction and peritoneal dissemination.

A 78-year-old woman receiving treatment for limited systemic scleroderma (SSc) underwent high anterior resection and partial liver resections for rectosigmoid colon cancer with multiple liver metastases. A year after surgery, an abdominal computed tomography (CT) demonstrated suspicion for peritoneal dissemination with an increase in ascites, and (18)F-fluorodeoxy glucose-positron emission tomography-CT was suggestive of carcinomatosis. We began to decompress the small intestine and administer octreotide. However, the intestinal obstruction did not improve. Although intestinal pseudo-obstruction caused by limited SSc was considered as a differential diagnosis, we performed an exploratory laparotomy because the possibility of peritoneal dissemination-associated obstruction could not be excluded. We observed a moderate amount of serous ascites and dilatation of the small intestine that was white in color, hard, and with limited contractility. There was no evidence of peritoneal dissemination nor of mechanical obstruction. Our experience thus shows the difficulty of distinguishing SSc-associated intestinal pseudo-obstruction from peritoneal dissemination.

Necrotizing Fasciitis Secondary to a Primary Suture for Anoperineal Trauma by Motorcycle Accident in a Healthy Adult.

A 41-year-old man experienced a swollen scrotum three days after a motorcycle accident and presented to our hospital. He had had a primary suture repair for anoperineal trauma in an outside hospital at the time of the injury. He presented to us with general fatigue, low grade fevers, and perineal pain. Abdominal computed tomography showed subcutaneous emphysema from the scrotum to the left chest. The sutured wound had foul-smelling discharge and white exudate. We made the diagnosis of necrotizing fasciitis and immediately opened the sutured wound and performed initial debridement and lavage with copious irrigation. We continued antibiotics and lavage of the wound until the infection was controlled. Fortunately, the necrotizing fasciitis did not worsen and he was discharged after 15 days. Our experience indicates that anoperineal injuries should not be closed without careful and intensive follow-up due to the potential of developing necrotizing fasciitis.

Preoperative Lower Body Mass Index Correlates with Poorer Prognosis in Patients Undergoing Curative Laparoscopic Surgery for Colorectal Cancer.

AIM: The aim of this study was to investigate the correlations between clinicopathological findings, laboratory data and survival outcome in patients undergoing curative laparoscopic surgery for colorectal cancer (CRC). PATIENTS AND METHODS: Clinicopathological findings and laboratory data, including tumor markers carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9) and systemic inflammatory response indicators, neutrophil-to-lymphocyte ratio (NLR) and modified Glasgow prognosis score (mGPS), for 204 patients (tumor stage I-III) undergoing laparoscopic curative surgery for CRC were collected. RESULTS: Elevated CA19-9 and mGPS, and body mass index (BMI) <20 kg/m(2) were significant indicators of poorer overall survival, while CA19-9 and BMI were validated as independent predictors of overall survival. In addition, BMI <20 kg/m(2) was a significant independent factor predictive of poorer disease-free survival. BMI significantly negatively correlated with NLR, which reflects the patients' immune response. CONCLUSION: Lower BMI is a promising predictor of recurrence and poor prognosis in patients treated by laparoscopic surgery for CRC with curative intent.

Unawareness of a Prolonged Retained Capsule Endoscopy: The Importance of Careful Follow-Up and Cooperation between Medical Institutions.

A 50-year-old man with anemia was referred to our hospital to undergo capsule endoscopy (CE), which revealed small intestinal ulcers. After 5 months of CE, he returned because of recurrent anemia without abdominal symptoms. Abdominal X-ray and computed tomography showed capsule retention in the small intestine at the pelvic cavity. The capsule remained at the same place for 7 days. We performed capsule retrieval by laparoscopy-assisted surgery with resection of the involved small intestine, including an ileal stricture. Resected specimen showed double ulcers with different morphologies, an ulcer scar with stricture, and a wide ulcer at the proximal side of the others. Each ulcer had different histopathological findings such as the degree of fibrosis and monocyte infiltration. These differences led us to consider that the proximal ulcer may have been secondarily induced by capsule retention. Our experience indicated that careful follow-up and the cooperation between medical institutions after CE examination should be undertaken for patients with incomplete examination, unknown excretion of the capsule, and/or ulcerative lesions despite the lack of abdominal symptoms. Additionally, a retained CE remaining over long periods and at the same place in the small intestine may lead to secondary ulceration.
