RESUMEN
A 72-year-old man underwent right hemicolectomy for transverse colon cancer(pT4aN1aM0, Stage â ¢B), after which he received adjuvant chemotherapy(capecitabine plus oxaliplatin[CAPOX])for 6 months. Three years after the first surgery, FDG-PET/CT revealed a tumor in the abdomen. He underwent a tumorectomy and adjuvant chemotherapy(CAPOX plus bevacizumab[BV])performed for 6 months. Two years after a tumorectomy, the CEA level rose again. He was diagnosed peritoneal metastasis again. A central venous(CV)port was implanted for access to the right internal jugular vein, and he received systemic chemotherapy(fluorouracil, Leucovorin, and irinotecan[FOLFIRI]plus BV)as an outpatient. One year after this recurrence, no peritoneal dissemination was detected by CT. Thereafter, total 49 courses of FOLFIRI plus BV were introduced, but chemotherapy was discontinued due to CV port-related infection. Three months later, low back pain appeared and became a diagnosis of spondylodiscitis. He had surgery, but follow-up CT performed 8 years after the first surgery detected multiple liver metastasis. It was considered necessary to take infection control measures during long-term chemotherapy.

Conversion surgery(CS)post chemotherapy for unresectable pancreatic cancer is often reported recently. Although it is still controversial about adaptation of CS, it could possibly be one of the useful choices of treatment for unresectable pancreatic cancer. We report 3 cases of CS which eventually turned out to be pathological complete response.

In laparoscopic surgery, intraabdominal examination is occasionally difficult due to restriction of operative field and palpation. This is a case report of a jejunal ectopic pancreas which was incidentally found during laparoscopic surgery. A 49-year- old male underwent endoscopic mucosal resection for a rectal polyp which pathologically resulted in 5,000 µm invasion in submucosa and lymphatic invasion. Laparoscopic low anterior resection was planned for the patient as an additional treatment. During the surgery, irregular shaped tumor-like lesion was incidentally found in jejunum which was located 30 cm distal side from the ligament of Treitz. Partial resection of jejunum was also performed for pathological diagnosis. Resected jejunal lesion was pathologically diagnosed as an ectopic pancreas of Heinrich classification type â . Ectopic pancreas is defined as pancreatic tissue which is discontinuous to pancreas, asymptomatic in most cases, but some reported cases of pancreatitis, forming fistula or cancerous change. Reporting with some literature review.

A 72-year-old man was referred to our department with suspected intestinal obstruction. CT showed irregular descending colon wall thickening. Lower endoscopy showed severe descending colon stenosis. Biopsy results were group 1. FDG accumulation of significant SUV was found in the lymph nodes on the left supraclavicular region, left axilla, right mediastinum, posterior part of the right diaphragmatic leg, around the abdominal aorta, and in the liver. The accumulation in the descending colon was not definitely neoplastic. Consequently of left axillary lymph node biopsy, axillary lymph node metastasis of colorectal cancer was suspected, and laparoscopic left semicolon resection was performed. Among the simultaneous distant colorectal cancer metastases, Virchow's and left axillary lymph node metastases are extremely rare(0.1%). We report a case of descending colon cancer with simultaneous Virchow's and left axillary lymph node metastases, with some literature discussion.

We report a 76-year-old woman with meningeal carcinomatosis after gastric cancer surgery. During adjuvant chemotherapy, metastasis to the left axillary and Virchow's lymph node was suspected. A resection biopsy revealed gastric cancer metastasis, and PTX plus RAM therapy was started. Due to RAM adverse events, the treatment was changed to weekly nab- PTX, which was continued for about 6 months. During the 8th course, she was hospitalized due to worsening headache and lightheadedness. Meningeal carcinomatosis was diagnosed by cytology of CSF examination and MRI findings. She died on the 16th day after admission. Meningeal carcinomatosis has a rapidly progressive course with poor prognosis. This case shows nab-PTX may have been able to control the progression.

BACKGROUND: Ectopic thymomas often occur in the upper mediastinum; however, they rarely arise in the middle mediastinum, especially on the dorsal side of the innominate vein and superior vena cava in the peribronchial region. CASE PRESENTATION: Six years prior, a 27-year-old female presented to our department and was diagnosed with locally advanced left breast cancer. First, we administered chemotherapy including an anti-human epidermal growth factor receptor 2 antibody. The size of the tumor was markedly reduced, and a radical operation involving mastectomy and axillary lymph node dissection was then performed. The patient underwent radiotherapy after the mastectomy, followed by trastuzumab therapy; she continued to receive endocrine therapy thereafter. She underwent computed tomography once a year after the surgery, and a nodule in the middle mediastinum on the dorsal side of the innominate vein and superior vena cava in the parabronchial region was detected at 4 years. We speculated that the nodule was a solitary mediastinal lymph node metastasis from her breast cancer; therefore, we performed thoracoscopic resection of the tumor. We diagnosed the tumor as a thymoma. Currently, the patient visits our hospital to receive continuous hormone therapy for her breast cancer, and the latest computed tomography scan demonstrated no metastases from or recurrence of her breast cancer or thymoma. CONCLUSIONS: We report a case of ectopic thymoma in the middle mediastinum. The tumor, which was detected during systemic therapy for locally advanced breast cancer, was located on the dorsal side of the innominate vein and superior vena cava in the parabronchial region and was indistinguishable from a lymph node metastasis from breast cancer.
RESUMEN
A 68-year-old man visited our hospital in October 201X, giving abdominal bloating as his primary symptom. We found tenderness at McBurney's point, high WBC values from a blood test, and swelling of the appendix in a CT scan, so he was diagnosed with acute appendicitis. On the same day, he had an emergency laparoscopic appendectomy, and he made good progress and was discharged from the hospital on the fourth day after the surgery. In the histopathological examination, he was diagnosed with acute gangrenous appendicitis and examination was concluded. August of the following year, ascites accumulation was found by CT scan, and he was introduced to the department of gastroenterology of this hospital for further testing. Lower endoscopy showed swelling of the appendix root, and he was diagnosed with adenocarcinoma in the biopsy. A CT scan found increased granular concentration in the omentum. Because of a diagnosis of appendix cancer/peritoneal dissemination, he underwent laparoscopic examination in October. Nodules were found scattered in the small intestinal mesentery and the omentum, and peritoneal dissemination was suspected during intraoperative rapid diagnosis. The operation was concluded with only laparoscopic examination. Because of the diagnosis of appendix cancer/peritoneal dissemination, mFOLFOX6 plus bevacizumab was implemented. Primary appendix cancer is a relatively rare disease, often diagnosed after surgery for appendicitis, reported of here 0.03% to 0.5% of cases undergoing appendectomy. We report a case of primary appendix cancer diagnosed 1 year after appendectomy, with the discussion of the literature.

A 69-year-old woman was referred to our hospital when the upper gastrointestinal endoscopy performed by the previous physician for detailed examination of upper abdominal discomfort indicated a duodenal tumor. Upper gastrointestinal endoscopy revealed a submucosal tumor with a central depression in the descending part of the duodenum. Contrast- enhanced computed tomography of the abdomen revealed a 23 mm tumor with contrast effect in the descending part of the duodenum contralateral to the Vater papilla. There was no lymphadenopathy or distant metastasis. Duodenal gastrointestinal stromal tumor was suspected, and localized duodenectomy was planned. Intraoperative findings showed that the tumor was located in the descending part contralateral to the Vater papilla with no evidence of surrounding invasion. Localized duodenectomy was performed, and on intraoperative rapid histopathological examination, an adenocarcinoma was suspected. As a result, the surgery was changed into pancreaticoduodenectomy. Based on the results of immunostaining, neuroendocrine tumor grade 2 was diagnosed. No lymph node metastasis was observed. The patient did not have recurrence of lesion 7 months after surgery.

BACKGROUND: Surgical indications for liver metastases from pancreatic ductal adenocarcinoma (PDAC) are lacking because outcomes are usually poor. However, liver resection and the recent progress in perioperative chemotherapy have been observed to improve survival. METHODS: We performed liver resection for liver metastases from PDAC only under the following criteria: (1) liver-only metastasis, (2) up to three tumors, and (3) no increase in the number of metastases during the 3-month observation period. No limitations were placed on the location or size of liver metastasis. In this study, we aimed to validate our surgical criteria and analyze factors affecting survival in patients with PDAC. RESULTS: Seventy-nine patients underwent curative resection for PDAC between 2005 and 2015. Seventy-one patients experienced recurrence, with liver-only recurrence in 17 patients. Among these, nine patients underwent liver resection and eight did not. The median survival time was significantly better for patients who underwent liver resection (55 months) than for those with other recurrences (17.5 months, p = 0.016). The median survival after liver recurrence was significantly better in the liver resection group (31 months) than in the non-liver resection group (7 months, p = 0.0008). The median disease-free interval (DFI) after pancreatectomy was significantly longer in the liver resection group (21 months; range, 3-44 months) than in the non-liver resection group (3 months; range, 2-7 months; p = 0.02). CONCLUSION: Good indications for liver metastases from PDAC include solitary metachronous tumors and longer DFIs.

This paper presents a case of critical anatomic variation in laparoscopic cholecystectomy, as an anterior segmental branch of segment V from the left hepatic artery passing anterior to the fundus of the gallbladder and coursing to the anterior hepatic segment. A 46-year-old man was admitted to our hospital complaining of hypochondralgia attributed to gallbladder stones. An aberrant artery crossed the ventral side of the neck of the gallbladder and ran into the right liver Glissonean sheath of segment V. During laparoscopic cholecystectomy, this artery was taped and exposed from proximal to distal ends, revealing an origin from the left hepatic artery with the vessel acting as the anterior branch of segment V to the liver. The cystic artery branching from the aberrant artery was found on the left side of the gallbladder. Laparoscopic cholecystectomy was performed with no injury to the hepatic arteries and the patient was discharged 3 days postoperatively. In general laparoscopic cholecystectomy, we expose only the area inside Calot's triangle. With such an approach, this type of aberrant hepatic artery may be injured intraoperatively without consequences. Detailed preoperative evaluation using modalities such as 3-dimensional reconstruction of CT and knowledge of variations in the hepatic artery will help avoid vessel injury.

A 71-year-old man presented with the chief complaints of constipation, melena, and weight loss, and sigmoid colon cancer was suspected on lower gastrointestinal endoscopy. The cancer was diagnosed as RAS wild type adenocarcinoma(tub2)on biopsy. Abdominal contrast-enhanced CT revealed a mass with a maximum diameter of 55mm in the sigmoid colon; therefore, bladder infiltration was suspected. The Group 1 lymph nodes were bulky, with a maximum diameter of 50 mm, and No. 253 lymph node was enlarged. No fistulas were found on cystoscopy. The sigmoid colon cancer was cT4b(bladder), N3, M0, cStage â ¢c. After performing a colostomy, neoadjuvant chemotherapy with mFOLFOX6 plus panitumumab was started. Radical surgery was performed after 3 courses of chemotherapy. The clinical treatment effect was PR, and the final histopathologi- cal examination revealed ypT3, ypN0(0/17), R0, ypStageâ ¡a. The therapeutic effect was Grade 2a. Postoperative adjuvant chemotherapy was performed for 6 months with mFOLFOX, and there have been no signs of cancer recurrence for 9 postoperative months. We experienced a case of colon cancer with suspected bladder infiltration, successfully treated with neoadjuvant chemotherapy and radical surgery.

The patient was a 75-year-old woman who had experienced left breast cancer(BT plus AX)in 1988. Local recurrences in the skin of the left chest wall appeared and were treated with operation, radiotherapy, and systemic therapy. Twenty-four years later, she developed continuous bleeding due to skin metastasis of the breast cancer and received Mohs chemosurgery and continued systemic therapy. After using Mohs paste 10 times, the skin surface healed and dried up. Improving the quality of life of patients with several symptoms such as skin cancer or metastatic skin lesions is essential in multidisciplinary therapy and Mohs paste was useful for the local control of the unresectable skin lesion.
