Study type
Description of intervention(s) / exposure
This study was done between May 2008 until September 2011, in our university hospital, about 191 cases of unilateral groin hernia, who were fit for general anesthesia and pneumoperitoneum with co2, without complicated hernia, or previous lower abdominal surgery were included. Exclusion criteria also included bilateral and, recurrent hernias. 191 cases were randomly distributed into two groups, using a big container containing 200 balls each ball had a number either one, or, two i.e one hundred ball containing number one, and, another one hundred ball contained number two. After explanation the surgical techniques and the side effects of each technique, and after getting a written consent from the patient to participate in the study, each patient was asked to withdraw one ball with a number, number one means that the patient had undergone laparoscopic transabdominal per-peritoneal mesh repair (TAPP) or group one, and, number two means that the patient belong to the group two or the open Lichtenstein free tension repair. Both procedures were performed under general anesthesia plus a mixtures of 0.5% Bupivacaine, and 1% lidocaine as 1:1 was used to achieve local anesthesia either in inguinal incision or at port site infiltration. Six cases were excluded from laparoscopic group I after surgery, as intra-operative finding of bilateral hernia, and, bilateral repair was done for them, and, they were excluded from the study.
TAPP approach with three port sites was performed in 88 unilateral inguinal hernia patients. With sharp dissection, a posterior peritoneal flap was obtained to expose the internal inguinal ring, the sac was dissected and reduced completely if small or partially excised left in situ if large, continued dissection medially exposing the inferior epigastric vessels, the floor of the inguinal canal or the transverses abdominus arch, Cooper’s ligament, and iliopubic tract.7 by 12 cm polypropylene mesh was used to cover the defect and fixed to the transverses abdominus arch, Cooper’s ligament, and iliopubic tract using stables. The peritoneum was closed over the mesh using stables. periumbilical fascial defect was closed with vicryl number 1.
The open repair was performed in 97 patients according to the technique, described by Lichtenstein et al., 1989
Lichtenstein, I.L., Schulman, A.G., Amid, P.K.: The tension-free hernioplasty.
Am. J. Surg. 159:188, 1989
In both groups skin closure was achieved using subcutaneous monocryl. Follow up of patient early after one month, then every six months or when needed. The definition of chronic pain was depending upon “International Association of the Study of Pain” which defined chronic pain as “pain lasting for 3 months or more,”
International Association for the Study of Pain, Subcommittee on Taxonomy. Classification of chronic pain: descriptions of chronic pain syndromes and definitions of pain terms. Pain 1986;3(Suppl): S1–226.
The Short-Form 36 (SF-36) was used in the first visit to assess quality of life. SF-36 has three levels: (1) items, (2) eight scales that aggregate, and (3) two summary measures (physical and mental health). The eight scales are well known as: physical functioning which expressed by (10 items), social functioning represented by (2 items), role physical limitations was expressed by (4 items), role limitations due to emotional problems as (3 items), mental health represented with (5 items), vitality had (4 items), bodily pain expressed by (2 items), and general health perception represented by (5 items), each item was represented with a score staring by zero for the worst and 100 for the best.
SPSS V 19 was used for data entry. All procedures, patient demographics, and follow-up data were recorded. Results were grouped and statistical significance was determined using the two-sample Wilcoxon rank-sum (Mann-Whitney) test.
The primary end point for the study was the total outcomes of the quality of life, the secondary end point was identifications of the complications of both techniques, recurrent rate, and, technical failure.
Average time of procedure is between 30-60 minutes
Group I or TAPP is the intervention group and Group 2 Lichtenstein free tension repair is the control but active group

Quality of Life using SF-36 Quality of Life Questionnaire and scoring for each question beginning at 0-100. data entry and analysis using SPSS V19.
these scores re-code the answers of each question of the SF-36 for example non of the time- a little of the time- some of the time-most of the time- all of the time for the question "Did you feel tired?' in question 9-i , these answers can be coded as 100-75-50-25-0

Secondary outcome [1] 294258 0
Complication and morbidity as (haemorrahge, seroma, haematoma, ileus, .....etc these data well be collected and SPSS V19 well be used for statistical analysis, presented as numbers and percentage in each group, and compared using the chi square test.

each patient had his own clinical file and follow up sheet in which each complication can be diagnosed clinically by examination assessment or radiological investigation as ultrasound if needed, all data recorded, and re-entered to computer system and SPSS program for statistical analysis
