ABSTRACT
Objective To explore the application value of vacuum sealing drainage (VSD) in wound repair after resection of pilonidal sinus.Methods The retrospective cross-sectional study were conducted.The clinical data of 11 patients with pilonidal sinus who were admitted to the China-Japan Union Hospital of Jilin University from April 2015 to June 2016 were collected.All the patients received resection of pilonidal sinus after preoperative antibiotic therapy,and then received postoperative VSD and regular treatments of anti-infection and dressing changes.Observation indicators:(1) treatment situations:surgical procedures,operation time,volume of intraoperative blood loss,gross specimens,results of postoperative pathological examination,postoperative treatment (VSD),growth condition of granulation tissue,duration of hospital stay and treatment expenses;(2) follow-up situations:cases with follow-up,follow-up time,wound healing,postoperative complications and disease recurrence.Follow-up using outpatient examination and telephone interview was performed to detect the wound healing,postoperative complications and disease recurrence up to July 2017.Measurement data with normal distribution were represented as (x)±s.Measurement data with skewed distribution were described as M(range).Results (1) Treatment situations:all the 11 patients underwent successful surgery for pilonidal sinus.The operation time and volume of intraoperative blood loss were respectively (79 ± 19) minutes and (10 ± 4) mL.Observation of gross specimens of 11 patients:hairs were scattered within the resected lesions in 7 patients,and hairs didn't found in 4 patients.Results of postoperative pathological examination of 11 patients:there were acute and chronic inflammation accompanied with granulation tissues in the subepithelial fibrous tissues,and discrete multinucleated giant cell reaction.Of 11 patients undergoing VSD,9 received VSD material changes for 3 times,2 received VSD material changes for once,and wounds were not sutured after VSD removal.The new granulation tissues of 11 patients were found at (5.9±1.3) days postoperatively.The duration of hospital stay and treatment expenses were respectively (33.3±8.3) days and (37 790± 8 811) yuan.(2) Follow-up situations:11 patients were followed up for 12-18 months,with a median time of 14 months.The wound healing time was (41.0±9.0)days.Of 11 patients with follow-up,10 were in the primary healing,1 who was complicated with wound infection and abscess of wound deep surface underwent sacral wound incision and drainage,gauze packing and routine dressing change,and then wound healed completely.There was no recurrence in 11 patients during the follow-up.Conclusions The VSD has great application value in managing wounds after resection of pilonidal sinus,with a lower incidence of wound infection and smaller scar,and it is worth recommending to patients with wide wounds,high tension and serious infection.
ABSTRACT
Objective To explore whether antibiotic prophylaxis is beneficial in tension-free in-guinal hernia repair Method A perspectiverandomized controlled study was conducted which included 1 28 patients who underwent tension-free inguinal hernia repair from July 201 1 to August 201 3.In the anti-biotic prophylaxis group,antibiotic was intravenously administrated within 30 minutes before surgery.In the control group,no preoperative antibiotic wasadministrated.The incidence of incision infection was com-pared between groups.Result Incision infectiondeveloped in onepatient of the antibiotic prophylaxis group and two patientsin the placebo group,indicating no significant difference between the groups(P >0.05).Conclusion Before tension-free repair,there is no real need to apply prophylactic antibiotics reg-ularlyfor inguinal hernia without high risk factors.
