Simultaneous presence of the hepato-spleno-mesenteric trunk, a common trunk for both inferior phrenic arteries, the left gastric artery, and a common hepatic artery that ran behind the portal vein in a patient with gastric cancer.

The celiac artery usually trifurcates into the common hepatic artery, splenic artery, and left gastric artery, but it is known to present several anatomical variations. In such cases, detailed knowledge of the variation is needed preoperatively to safely perform surgery. A 77-year-old woman was referred to our hospital for the treatment of gastric cancer. She had a triple anatomical variation: simultaneous presence of the hepato-spleno-mesenteric trunk, a common trunk for both inferior phrenic arteries and the left gastric artery, and a common hepatic artery that ran behind the portal vein. We detected this variation on routine preoperative multidetector computed tomography angiography, and safely and adequately performed laparoscopic distal gastrectomy.

[Three Cases of Solitary Brain Metastasis in Advanced Gastric Cancer].

We have experienced 3 cases of solitary brain metastasis after radical surgery in advanced gastric cancer. All of them have similar characteristics such as, upper third location, solitary metastasis to the cerebellum, and no other organ metastasis. As there is a risk of brain hernia, resection have been underwent first, and radiotherapy administered after surgery. One case has been provided over 2-year survival.

Using the preoperative prognostic nutritional index as a predictive factor for non-cancer-related death in post-curative resection gastric cancer patients: a retrospective cohort study.

BACKGROUND: Gastric cancer (GC) is the third leading cause of cancer-related mortality worldwide. Therefore, identifying the predictive factors for surgical morbidity, disease recurrence, and long-term survival is necessary for preventing GC patient mortality. We aimed to evaluate the factors that contribute to the poor prognoses of GC patients. METHODS: In this retrospective cohort study, the data of 182 patients who underwent curative gastrectomy for GC was reviewed. The data included patients' cancer stage and preoperative prognostic nutritional index (PNI) score. We identified the prognostic factors using a univariate analysis and the multivariable Cox proportional hazards model. The associations between PNI and other clinicopathologic factors for GC were compared via logistic regression analysis. Kaplan-Meier curves were used to evaluate patients' survival in relation to these factors. The median follow-up period was 3.5 years. Multivariable cumulative incidence method based on Fine and Gray's method was performed to evaluate the association between non GC-related death and potential prognostic factors. RESULTS: There were significant differences in overall survival (OS) between comorbidities (myocardial infarction: P = 0.040, liver disease: P = 0.017), cancer stages (I vs. II: P = 0.049, I vs. III: P < 0.001), tumor size (P = 0.002), lymphatic vessel infiltration (P < 0.001), serum CA 19-9 (P = 0.024), and PNI scores (P = 0.002). Moreover, only PNI score was determined to be an independent prognostic factor for survival. Furthermore, stage I GC patients with high PNI scores had significantly longer OS than those with low PNI scores (P < 0.001), but these groups were not significantly different in terms of recurrence-free survival (P = 0.756). Stage II and III GC patients showed no significant difference in terms of OS and recurrence-free survival, regardless of PNI scores. Finally, Fine and Gray's method revealed that PNI score was an independent prognostic factor for non-GC-related death (P < 0.001). CONCLUSIONS: Preoperative PNI is effective in predicting the prognosis of post-curative gastrectomy GC patients and can be used to predict non-GC-related death and the OS of post-curative gastrectomy patients with stage I GC.

Palliative surgery for advanced gastric cancer: Partial gastrectomy using the inverted laparoscopic and endoscopic cooperative surgery method.

INTRODUCTION: Laparoscopic and endoscopic cooperative surgery (LECS) is a minimally invasive hybrid procedure that facilitates the precise dissection of gastrointestinal malignancies. We report the use of LECS as palliative treatment for a patient with advanced gastric cancer at a high risk due to comorbidities. PRESENTATION OF CASE: A 68-year-old woman with general malaise was admitted to the hospital and received multiple transfusions for anemia. Endoscopy examination detected an ulcerative lesion in the stomach. She was at high risk due to comorbidities including liver cirrhosis (Child-Pugh score B), aortic stenosis, and coronary artery stenosis requiring operative treatment. DISCUSSION: Imaging revealed no evidence of metastasis. We resected the tumor using LECS to control bleeding. Postoperatively, there were no short-term complications, and there was no recurrence during 6-month follow-up. CONCLUSION: LECS as palliative treatment may be a viable option for high-risk patients with advanced gastric cancer.

[Twenty-Five Cases of Locally Advanced Rectal Cancer That Underwent Laparoscopic Surgery after Preoperative Chemotherapy].

Several recent reports have described the administration of preoperative chemotherapy for locally advanced rectal cancer. In our hospital, preoperative chemotherapy based on oxaliplatin was administered for locally advanced rectal cancer with a tumor diameter of 5 cm or more and half semicircularity or more, and curative resection with laparoscopic surgery was performed after tumor shrinkage. We have experienced 25 cases that underwent preoperative chemotherapy for local advanced rectal cancer in our hospital from May 2012 to April 2016. No tumor increased in size during preoperative chemotherapy and there were no cases where R0 resection was impossible. In addition, no distant metastasis during chemotherapy was observed. Postoperative complications were observed in 3 cases(12%), and anastomotic leakage was observed in 1 case (4%), but conservative treatment was possible. Multidisciplinary treatment of preoperative chemotherapy and surgery should be considered as a therapeutic strategy for locally advanced rectal cancer, mainly in medical institutions without radiation treatment facilities.

Late-onset diaphragmatic hernia after percutaneous radiofrequency ablation of hepatocellular carcinoma: a case study.

Percutaneous radiofrequency ablation (RFA) is widely used as an effective treatment of liver tumors. Several reported complications associated with RFA are due to thermal damage of neighboring organs. The present report presents a case of diaphragmatic hernia associated with RFA and hepatocellular carcinoma (HCC). A 72-year-old woman with S5 and S8 HCCs was treated repeatedly with RFA and transcatheter arterial chemoembolization for 3 years. After the third course of RFA to target the recurring S5 HCC, acute abdominal pain and dyspnea suddenly occurred. Contrast-enhanced computed tomography revealed intrusion of the transverse colon through the right diaphragmatic hernia. In addition, the colon was dilated and showed changes suggestive of ischemic conditions. An emergency surgery was performed to close the hernia by using non-absorbable sutures to preserve the colon. The patient was discharged without any complications 13 days after the surgery. The first-line treatment of this disease involves surgical intervention. Diaphragmatic hernia is a rare complication of RFA. The present case suggests that patients who undergo several rounds of RFA require surveillance for diaphragmatic hernias.
