[Long-Term Suppression with First-Line Chemotherapy(FOLFIRI plus BV)for Peritoneal Metastasis].

A 72-year-old man underwent right hemicolectomy for transverse colon cancer(pT4aN1aM0, Stage ⅢB), 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.

[A Case of Unilateral Interstitial Lung Disease in a Patient Treated with Oxaliplatin, 5-Fluorouracil, and Leucovorin].

Respiratory symptoms are rarely reported as side effects of oxaliplatin, 5-fluorouracil, and Leucovorin(FOLFOX)therapy. We report a case of a patient with FOLFOX-induced unilateral interstitial pneumonia. The patient was a 68-year-old man who underwent ileocecal resection of cecum cancer. FOLFOX regimen was started as an adjuvant chemotherapy. After the administration of 11 courses, he visited our hospital with fever, dyspnea, and anorexia. We diagnosed this as FOLFOX- induced unilateral interstitial pneumonia through a blood test, chest radiograph, computed tomography, and bronchoscopy. Treatment was started with 30 mg of prednisolone, and the dosage was gradually decreased. The patient responded well to the treatment and was discharged from the hospital without any complications on the 33th day after admission.

Postoperative diaphragmatic hernia with upside-down stomach: a case report.

A 31-year-old man presented to our hospital's Emergency Department with sudden epigastric pain and vomiting. He had undergone endoscopic resection via the retroperitoneal route for a retroperitoneal tumor located in the left diaphragmatic crus of the esophageal hiatus at another hospital 8 months previously. Radiography and computed tomography showed inversion of the stomach beyond the diaphragm into the thoracic cavity, with the gastroesophageal junction serving as the fulcrum point. This finding led to a diagnosis of postoperative diaphragmatic hernia accompanied by an upside-down stomach (UDS). The prolapsed stomach in the thoracic cavity was reduced to the abdominal cavity using laparoscopic surgery. The postoperative course was favorable, and the patient was discharged from the hospital on postoperative day 7. No recurrence has been observed in the past 5 years. The pathological condition of a UDS observed in esophageal hiatal hernias may be found in postoperative diaphragmatic hernias. Laparoscopic surgery for a postoperative diaphragmatic hernia with a UDS is considered a useful surgical procedure. Laparoscopic surgery can simultaneously confirm the viability of the herniated organs, reduce the organs to the abdominal cavity, and close and reinforce the diaphragm.

Incisional hernia after extreme lateral interbody fusion on the lumbar spine: A case report.

INTRODUCTION: Extreme lateral interbody fusion is a minimally invasive lateral transpsoas approach for spine surgery. We herein report a case of an incisional hernia after an extreme lateral interbody fusion on the lumbar spine that was successfully treated by laparoscopic surgery with intraperitoneal onlay mesh repair. PRESENTATION OF CASE: A 78-year-old woman was referred to our hospital with a complaint of left abdominal bulge and pain. She had undergone an extreme lateral interbody fusion for a lumbar spinal canal stenosis from L1 to L4 a year prior. Abdominal computerized tomography showed a left lumbar incisional hernia, and laparoscopic surgery was performed. The hernia orifice was sutured closed and covered with mesh. The patient was discharged five days after the operation with no complications. DISCUSSION: When performing XLIF for a spinal disorder, the muscles should be separated bluntly along their fibers to prevent muscle atrophy, and the incised fascia should be securely sutured closed. Abdominal wall incisional hernias can occur after spinal surgeries such as extreme lateral interbody fusion. CONCLUSION: Laparoscopic repair for abdominal wall incisional hernia after spine surgery is safe and feasible.

Laparoscopic treatment for adult inguinal hernia with cryptorchidism: A case report.

INTRODUCTION: Cryptorchidism or undescended testis is the most common disorder of male children, which is often diagnosed and treated during childhood. Adult patients with cryptorchidism are uncommon. Herein we report the case of adult inguinal hernia with cryptorchidism successfully treated by laparoscopic surgery simultaneously. PRESENTATION OF CASE: We report a case of 68 year-old-man who was admitted to our hospital with a complaint of bulge and pain in the right groin area from 2 weeks before. CT or MRI revealed a right inguinal hernia and an undescended testis in the right inguinal canal. He was diagnosed with right inguinal hernia accompanied by cryptorchidism. Laparoscopic transabdominal preperitoneal repair (TAPP) and orchiectomy were performed simultaneously. Postoperative period was uneventful and he was discharged home on the 1st postoperative day. Pathological examination of the specimen was reported as atrophic testis with no malignancy. There has been no recurrence during a follow-up. DISCUSSION: To our Knowledge, the case report of adult inguinal hernia with cryptorchidism treated by laparoscopic surgery is rare. All cases recommended the feasibility of laparoscopic surgery. CONCLUSION: Adult inguinal hernia with cryptorchidism is a rare condition. TAPP and simultaneous laparoscopic orchiectomy for inguinal hernia with cryptorchidism were safe and feasible. It could be the first surgical option for the treatment of such adult patients.

[A Case of Primary Breast Cancer and Gastric Cancer Metastasis to the Skin-Usefulness of Immunohistochemistry in Differentiating Primary Breast Cancer from Metastatic Breast Cancer].

We herein report the case of a 76-year-old female patient who had undergone gastrectomy for advanced gastric cancer (histologically tubular adenocarcinoma)before 5 months, presenting with abdominal skin tumor. A skin biopsy revealed tubular adenocarcinoma. Positron emission tomography-computed tomographic scanning detected right breast tumor. A partial mastectomy of the right breast and local resection of abdominal skin tumor were performed and both tumors depicted similar histology of tubular adenocarcinoma in routine pathological examination. Immunohistochemically, positive for CDX2 and MUC5AC in previously resected gastric cancer and skin tumor tissues, whereas negative for both antigens in breast cancer. Thus, the final pathological diagnosis demonstrated skin metastasis originating from gastric cancer and primary breast cancer(invasive ductal carcinoma)histologically mimicking gastric cancer. We emphasize difficulties in diagnosis of this situation and that immunohistochemistry is helpful to distinguish primary breast cancer from gastric cancer metastasizing to the breast.

Continuous-flow synthesis of vitamin D3.

A highly efficient, two-stage, continuous-flow synthesis of vitamin D(3) from provitamin D(3) was achieved. The developed method afforded the desired product in high yield (HPLC-UV: 60%, isolated: 32%) and required neither intermediate purification nor high-dilution conditions.
