This is the case of a 72-year-old man in whom multiple colorectal cancers including rectal and appendiceal cancers and synchronous S3 liver metastases were observed in 2014, and resection was performed in 2 stages. In 2017, a single recurrence was found in the liver S8, and he underwent a liver S8 sub-segmental resection. Implantation of a CV port for postoperative chemotherapy was planned. At the time of insertion, the catheter was punctured from the exterior portion of the left subclavian vein to avoid the pinch-off syndrome wherein the catheter is crushed between the clavicle and the first rib. Subsequently, FOLFOX therapy was started, but it was discontinued because of allergic symptoms, which appeared during the third course. Two years after the CV port was implanted, a catheter fracture was found on a chest X-ray performed during a regular visit. Since the detached catheter did not fall into the vein, it was possible to remove the port under fluoroscopy. When a catheter is implanted, even under ultrasound guidance, it is considered important to always keep in mind the possibility of a catheter fracture and to detect and respond to it early.

We report a case of malignant stenosis due to recurrence of lymph node metastasis treated with laparoscopic gastrojejunal bypass. A 83-year-old man who underwent chemoradiotherapy for esophageal cancer(cT3N2M0). About 3 and half years after chemoradiotherapy, he was referred to hospital for vomiting. As a result of the examination, we diagnosed malignant stenosis of descending part of duodenum due to retroperitoneum lymph node recurrence of esophageal cancer. We performed laparoscopic gastrojejunal bypass operation because we suggested self-expandable metallic stent make easy to migrate into anal side of the duodenum. The postoperative course was good. He was enrolled in oncology department on the 21 days after the operation. Gastroduodenal stenosis is common pathology by malignant tumor. Gastrojejunostomy and placement of self-expandable metallic stent is commonly performed for malignant gastroduodenal obstruction. Endoscopic metallic stent placement is minimally invasive treatment for malignant stenosis of the intestine, however sometime the stent placement will make easy to migrate by extra compression. Gastrojejunostomy mat be more safety than endoscopic stent placement for the malignant gastroduodenal obstruction.

A 63-year-old man was admitted for the evaluation of Hb 4.8 g/dL anemia. He underwent colon fiberscopy and was subsequently diagnosed with synchronous cancers of the ascending colon and rectum. He underwent laparoscopic ileocecal resection and low anterior resection with 2 segmental anastomoses. The histopathological diagnosis of A/C and rectal cancer was Stage Ⅱ and Stage Ⅲa, respectively. His treatment was completed after 6months of adjuvant chemotherapy with oral TS-1, which was followed by a subsequent 2 year follow-up study, without disease recurrence. Operations of synchronous cancers with 2 segmental anastomoses usually require longer surgical time and are associated with more postoperative complications compared with a single segmental anastomosis. We report a case of synchronous colorectal cancer successfully treated by laparoscopic surgery with 2 segmental anastomoses.

The patient was an 85-year-old man who received chemotherapy with gemcitabine for 2 years 9 months under the diagnosis of unresectable locally advanced pancreatic body and tail cancer. He visited our hospital because of anorexia, upper abdominal fullness, and vomiting. A CT scan showed severe stenosis in the third portion of the duodenum, which was associated with the direct invasion of the advanced pancreatic cancer. Upper gastrointestinal fiberscopy revealed a severe duodenal obstruction; however, pancreatic cancer exposure within the duodenal mucosa was not observed. As the stenosis of the duodenum was relatively smooth because of the cancer invasion into only the submucosa, deviation of the metallic stent was possible, so we performed laparoscopic gastrojejunostomy. We started the surgery with 5-port settings. A slit was made in the gastric body by using ENDO-GIA®, and bypass surgery with a Roux-en-Y anastomosis was performed. The postoperative course was good, and oral intake resumed on the third postoperative day. Thereafter, he could leave the hospital with good progress and received systemic chemotherapy using gemcitabine. In the present case, an extramural gastrointestinal stenosis without cancer that was not exposed in the gastrointestinal mucosa was poorly fixed with gastrointestinal metallic stents and use of a deviating metallic stent was reported, so we chose laparoscopic gastrojejunostomy. In addition, after undergoing laparoscopic surgery, which is a minimally invasive treatment, he recovered quickly and shifted early to systemic chemotherapy. Herein, the usefulness of laparoscopic gastrojejunostomy for extramural stenosis is reported with a review of related literature.

A 51-year-old female presented to our hospital with a chief complaint of abdominal pain. A blood test showed high ALP value(7,001 IU/L), and the abdominal CT showed a mass lesion of 20 cm in diameter with calcification and infiltrated surroundings. From these findings, we diagnosed the patient with peritonealcancer pre-operatively. The intraoperative findings showed an advanced tumor infiltrated into the sigmoid, transverse colon, small intestine and uterus. There were multiple suspected metastasis tumors in the peritonealcavity. Therefore, we resected the tumor as much as possible without curative surgery. Pathologically, the spindle cells were growing with bone formation. Immunostaining showed negative epithelial markers. The tumor protruded out of the intestinal wall, and the patient was diagnosed with extraskeletal osteosarcoma in the omentum. Chemotherapy with doxorubicin and cisplatin was initiated. Because of the disease progression and the presence of side effects, the patient discontinued chemotherapy and died 4 months after the operation. Extraskeletal osteosarcoma is a very rare tumor with poor prognosis. We reported a case of extraskeletal osteosarcoma in the omentum and review the literature.

Among patients who receive enteral nutrition through a gastric fistula, some are concomitantly administered viscosity modifiers to avoid aspiration pneumonitis caused by gastroesophageal reflux. These patients(and families)often bear the high economic and care burdens associated with enteral nutritional management. We developed an outpatient-based pharmacy service through multidisciplinary cooperation, facilitating a shift from enteral nutrition to semi-solid formula. This shift is expected to reduce the economic burden by approximately 120 thousand yen, and the hours of care by about 550 hours annually. Owing to family circumstances or economic conditions, some patients(and families)do not receive at-home guidance of pharmaceutical management by pharmacists. The family members of such patients visit the pharmacy to obtain the prescribed medications. Such patients and families could be supported within the outpatient-based pharmacy services, through proactively participating in home health care daily(collaborative relationship with the local community)and re-counting experiences of providing home guidance of pharmaceutical management.
