Objective: To study the clinical characteristics, paraclinic, the operative indication and treatment outcomes operation of colorectal polyposis by laparoscopic. Marterials: 12 patients with colorectal polyposis, is surgically the subtotal colectomy, and the total colorectomy by laparoscopic from 11/2012 to 4/2015 at Digestive Surgical Department of Hue Central Hospital. Method: Prospective study, all patients were examined clinically, endoscopic colorectal, operative indication, the type of surgery, lengh of post-operative stay, complications, and pathology. Results: From 11/2012 to 4/2015. We had overalled 12 patients: 8 males and 4 females, the mean patient was 36.33 ± 19.5 years of age (15-71). Dyspepsia 66.7%, bloody stools 100%. Laparoscopic segmental bowel resection in four (33,3%) cases: right hemicolectomy in one (8.3%), resection of transverse colon in one (8.3%), left hemicolectomy in two (16.7%), and totally colorectomy in eight (66.7%) by laparoscopic surgery. The mean post-operative hospital stay was 10.1 ± 3.8 days. The early complication: fistula anastomosis in one (8.3%), patients recovered after conservative treatment, no bleeding and no wound infection. The pathology is adematous polyps 91.7% and hyperplasia polyps 8.3%. Conclusion: Laparoscopic surgery is currently the technique of choice. The resection of colorectal polyposis is the method safe, effective, high success, low rate complications. Key words: laparoscopic, polyposis, colo-rectal polyposis, hemicolectomy

Background: Inguinal hernia is a common disease in general surgery. Treatment with Lichtenstein procedure is applicate in the worldwide. Study objectives: The ultrasound may be evaluate the using of polypropylene mesh by Lichtenstein for inguinal hernias.Materials and Method: Prospective study in 176 patients with 193 inguinal hernias. Hernioplasty by Lichtenstein procedure from September 2009 to December 2012 in Hue Central Hospital. Results: The right hernia 49.4%, left hernia 40,9%, bilateral hernia 9.7%, fibromesh 100%, thick fibromesh 2.53 ± 0.23 mm, seroma 3,6%. Conclusions: Sonography can be effective for evaluation of fibromesh and complication after mesh repair of inguinal hernias. Key words: Inguinal hernia; Lichtenstein, ultrasound

Background: Inguinal hernia is a common disease in general surgery, it is treated by total extraperitoneal (TEP) procedure. It is also applicated in the worldwide. Study objectives: The results of use polypropylene mesh by TEP for inguinal hernias. Materials and Method: Prospective study of 93 patients with 102 inguinal hernias hernioplasty by TEP from November 2010 to March 2013 in Hue Central Hospital.

Introduction: To describe clinical and para-clinical characteristics of bile duct stones and results of laparoscopic choledochotomies in management of bile duct stones. Materials and methods: Retrospective and prospective study in 152 bile duct stones patient, who underwent laparoscopic choledochotomy with or without usage of flexible bile ducts scope and electrohydraulic technique, from January 2009 to May 2019 at Hue Central Hospital. Results: Mean age 54,2 (22 - 84), 66 male and 86 female, mean operative time: 135 minutes (90 - 235), intraoperative complications: 3,29%, open conversion: 5,92%. Complete stone clearance was achieved in 91,6% patients. Postoperative complications: 7,69%. Conclusions: Managementofbileductstonesbylaparoscopiccholedochotomy is safe and effective with high percentage of stones clearence, as well as low intraoperative and postoperative complications. This procedure can achieve good results if bile ducts scope and electrohydraulic technique were concomitantly applied.
