[A Case of Long-Term Survival after Pancreatoduodenectomy for Gastric Cancer with Pancreatic Invasion].

A 79-year-old woman with symptomatic pyloric stenosis was diagnosed with advanced gastric cancer. CT revealed that the tumor had invaded into the pancreatic head.Since no contraindications were found at laparotomy, we performed pancreatoduodenectomy. The histopathologic diagnosis was pT4b (panc), pN3a (11/35), P0, CY0, H0, M0, pStage ⅢC, R0. The patient received adjuvant chemotherapy with S-1 for 1 year. The patient has survived without recurrence for more than 2 years. The efficacy of pancreatoduodenectomy for advanced gastric cancer is still controversial. Pancreatoduodenetomy may be indicated for selected cases of advanced gastric cancer, if an R0 resection can be achieved.

[The treatment plan for squamous cell anal canal carcinoma].

The current treatment plan for squamous cell anal canal carcinoma using chemoradiotherapy (CRT) is becoming more standardized. We use CRT rather than surgery to select the appropriate treatment. We experienced 4 patients treated with abdominoperineal resection(APR), of which 1 underwent adjuvant CRT. We also experienced 3 patients treated with radiotherapy(RT) and 2 treated with CRT. A patient treated with RT underwent APR because of radiation colitis. RT and CRT are advantageous for quality of life and are expected to be effective for controlling the disease. We hope that the standard treatment plan for anal cancer in Japan will be determined on the basis of histological features.

[A surgical (right lobectomy) case of liver metastasis of colon cancer after chemotherapy using mFOLFIRI and cetuximab].

A man in his early seventies underwent low anterior resection and partial resection of the liver for the rectal cancer and liver metastasis. However, 4 months after the surgery, he was found to have a liver tumor at S5 and S7 by abdominal CT scan. Then, he underwent chemotherapy (mFOLFOX6), but the metastatic tumor was progressive. We selected FOLFIRI + cetuximab regimen for second-line therapy to resect the metastatic tumor. As the metastatic lesion was become smaller after 4-course of the regimen including cetuximab, we decided to perform a radical resection. We conducted a right lobectomy of the liver, and the tumor was completely resected.

[A surgical (pancreatoduodenectomy) case of lymph node metastatic recurrence of colon cancer after chemotherapy].

A woman in her fifties underwent a right hemicolectomy (D3) for cancer of the ascending colon in October 2007, definitively and pathologically diagnosed as papillary adenocarcinoma invading to the subserosa, and no metastasis was detected to lymph node. But 13 months after the surgery, she was found to have a mass near the anastomosis by an abdominal CT scan. Colonoscopy showed an evaluating lesion with ulcer in the anal side of the anastomosis. We tried to resect the metastasis, but it was not resectable because of the invasion to the pancreas. The mFOLFOX regimen was effective. After the chemotherapy (6 courses), we decided to perform a radical resection. We conducted pancreatoduodenectomy in May 2009. She is still alive 12 months after surgery.

Learning curve for laparoscopic transabdominal preperitoneal repair: A single-surgeon experience of consecutive 105 procedures.

INTRODUCTION: Based on previously published papers, the learning curve for laparoscopic groin hernia repair is controversial. The purpose of the present study was to evaluate the learning curve for laparoscopic surgery for groin hernia in a local hospital setting. METHOD: We analyzed 100 consecutive cases of laparoscopic transabdominal preperitoneal repair performed by a single surgeon at a single facility from April 2013 to December 2015. The total operative time was divided into three parts: (a) preparing the peritoneal flap, (b) unfolding the mesh, and (c) suturing the peritoneum. A cumulative sum method for the total operative time and duration of the three parts was used to determine the learning curve. RESULTS: The learning curve was overcome after 75 cases based on cumulative sum analysis of the total operative time. The cumulative sum analysis of the times to unfold mesh and to suture the peritoneum indicated that the learning curve was overcome after 22 and 32 cases, respectively. The learning curve for preparing the peritoneal space was correlated with that for the entire procedure. No cases of recurrence were encountered. CONCLUSION: At least 75 cases were needed to overcome the learning curve for laparoscopic transabdominal preperitoneal repair.

[The introduction of the clinical study in the general hospital].

Our hospital fights against a clinical study clearly. However, our hospital did not participate in a clinical study here. When I widened a clinical study in cooperation with the staff, I make a progress report. I started a clinical study only with a doctor first. Therefore it was recognized many problems happened and to promote a clinical study without cooperation of the work of many kinds. I studied with the staff to promote a clinical study and deepened understanding. Thereafter the clinical study was led by a nurse of the chemotherapy room; , in addition, was able to get various cooperation from a skiagrapher. When OGSG0603 began, the nurse and the pharmacist served to become the key than a doctor. I was able to promote a clinical study by cooperation of much staff. In addition, I was able to carry out the system improvement of each section by performing a clinical study.
