Establishment and Clinical Application of the Concept of Invalid Extraction Rates in Follicular Unit Extraction.

Objective: This study aims to establish the concept of invalid extraction rates in follicular unit extraction and evaluate its clinical value.

Methods: The present study involved 30 patients with alopecia. Three young surgeons (nominated A, B, and C) each performed follicular unit extraction on a randomly selected portion of the donor site of each patient for ten minutes.

Reducing the gastroesophageal reflux with lip-type reinforcement technique during intrathoracic esophagogastrostomy.

Background/aims: Gastroesophageal reflux is a significant problem after esophagogastrostomy, and impact considerably upon the quality of patients' lives. Aims of this study were to evaluate the operative effects in prevention of reflux with lip-type reinforcement during intrathoracic esophagogastric anastomosis.

Methodology: From January 2005 to December 2009, 216 patients received circular stapled esophagogastrostomy with lip-type reinforcement (LR group), and 69 patients with standard reinforcement (SR group) at our hospital.

Clinical application of mucosal valve technique for anastomosis during esophagogastrostomy.

Background: The study aims to compare the efficacy in prevention of anastomotic complications using layer-to-layer mucosal valve technique versus circular stapled technique for esophagogastric intrathoracic anastomosis after resection for esophageal and gastric cardiac carcinoma.

Methods: From January 2005 to December 2010, 136 patients received layer-to-layer mucosal valve technique (LM group), 219 received circular stapled anastomosis (CS group) after curative intent resection for esophageal and gastric cardiac carcinoma. The technique details were reported and the clinical results were analyzed.
