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.

[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 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.

[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.

[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.
