Objective To investigate the application of transverse fascia in inguinal hernia repair. Methods In this study, 617 patients underwent inguinal hernia repair between January 1990 and December 2005 in our hospital were included, which were divided into two groups according to different operative ways: transverse fascia method group (n=337) and Bassini method group (n=280). Then intraoperative results, postoperative complications, and rehabilitated results of patients in two groups were compared. Results Compared with Bassini method group, the patients in transverse fascia method group did not show significant difference in operative time and blood loss during operation (Pgt;0.05). The differences of severe postoperative pain, testicular swelling, the time of the body’s restore for normal activities, and recurrence rate of patients between two groups were significant (Plt;0.05), while the difference of hematoma of scrotum and infection of incisional wound (Pgt;0.05). Conclusion The strengthening of posterior wall by transverse fascia and reconstruction of inner ring is a simple and effective method for inguinal hernia repair.
ObjectiveTo investigate the surgical skills and clinical effects of the laparoscopic transabdominal preperitoneal (TAPP) inguinal hernia repair in treatment of recurrent inguinal hernia with plug prefix mesh. MethodsThe clinical data such as operation time, intraoperative blood loss, postoperative hospital stay, and postoperative complications of 87 patients with recurrent inguinal hernia reoperated in laparoscopic TAPP after inguinal hernioplasty with plug prefix mesh (recurrent hernia group), in the Department of Gastroenterology and Hernia surgery of the First Affiliated Hospital of Kunming Medical University from January 2011 to December 2013, were retrospectively analyzed, which were compared with the 834 incipient inguinal hernia patients operated first by TAPP (incipient hernia group) at the same time. ResultsThe operations were completed successfully in all of the 921 patients without conversion to open surgery. The operation time and intraoperative blood loss in the recurrent hernia group were significantly more than those in the incipient hernia group (P=0.000, P=0.000), the postoperative hospital stay had no signifcant difference between two groups (P=0.057). No recurrences were observed in the recurrent hernia group and incipient hernia group for following-up of (31±4) months and (28±6) months, respectively. Compared with the incipient hernia group, the rates of postoperative pain on day 30 and seroma on day 1 and 3 were higher in the recurrent hernia group (P=0.001, P=0.040, P=0.003, respectively). There were no severe complications such as collateral damage, foreign body sensation, incision infection, intestinal obstruction and so on in the two groups. ConclusionsThe laparoscopic TAPP inguinal hernia repair is safe and effective for patients with recurrent inguinal hernia with plug prefix mesh. More skills are required to reduce the complications. The operation time and intraoperative blood loss in reoperated patients with recurrent inguinal hernia are more than those in patients with incipient inguinal hernia. The rates of seroma on day 1 and 3 are also higher.
Objective To explore the method and effectiveness of laparoscopic bundled fastigiated mesh in repairing inguinal hernia. Methods Between January 2003 and December 2009, 1 215 patients (1 363 sides) with inguinal hernia were treated. There were 1 132 males (1 268 sides) and 83 females (95 sides), aged from 18 to 89 years (median, 58 years). The cases included 1 187 cases (1 329 sides) of primary hernia and 28 cases (34 sides) of recurrent hernia. There were indirect inguinal hernia in 728 cases (786 sides), direct inguinal hernia in 416 cases (499 sides), femoral hernia in 43 cases (45 sides), and unusual hernia in 28 cases (33 sides). According to the hernia classification criteria, there were 31 cases (38 sides) in type I, 683 cases (754 sides) of type II, 403 cases (452 sides) of type III, and 98 cases (119 sides) of type IV. The disease duration was 1 to 9 days with an average of 3.8 days. To repair the hernia, the bundled fastigiated mesh was patched through the internal inguinal ring and fixed on the internal inguinal fascia by three-point fixation. The mesh would be wrapped in the peritoneum by purse-string suture. Results The surgeries were performd successfully. The operative time ranged from 18-32 minutes (mean, 22 minutes). Postoperative tractional pain in the inguinal region occurred in 19 cases (21 sides), acute uroschesis in 8 cases, and far-end hernial sac effusion in 2 cases (2 sides); all were cured after symptomatic treatment. All incisions healed by first intention, and no complications of fever, infection, or hematoma occurred. A total of 1 095 cases (1 182 sides) were followed up 1 to 7 years (median, 3 years and 9 months). Five patients died of medical illnesses at 1-3 years after operation. Three cases recurred and then were cured by a second surgery. No intestinal adhesion or obstruction occurred. Conclusion The bundled fastigiated mesh in laparoscopic inguinal hernia repair has the advantages of minimal invasiveness, easy-to-operate, less complications, and lower recurrence rate.
Objective To investigate the value of laparoscopy in resetting and repairing of inguinal incarcerated hernia. Methods Clinical data of 11 patients with acute inguinal incarcerated hernia treated with laparoscopy from March 2007 to February 2008 were reviewed, including 3 cases of direct inguinal hernia and 8 cases of oblique inguinal hernia. Results There were 7 patients with incarcerated hernia who were reset automatically after general anaesthesia, and 4 patients who were reset with laparoscopy. All the hernias were repaired with the transabdominal preperitoneal (TAPP) method after observed or improved the blood cycle of the incarcerated intestinal tract under laparoscopy. Average follow-up time was 6.6 months (2-12 months) after operation. Good recover and no recurrence were showed in all patients. Conclusion Laparoscopy is a safe technology in resetting and repairing of inguinal incarcerated hernia
Objective To discuss the prophylactic effect of handling inguinal nerves correctly duing Lichtenstein inguinal hernia repair on chronic pain after operation. Methods 158 patients with inguinal hernia who were treated in our hospital from February 2007 to March 2010 were given Lichtenstein hernia repair. The ilioinguinal nerves were carefully identified and preserved during the operation, the nerve excision had been carried on only in the cases of existing nerve injuried or interference with the position of the mesh. Results The identification rate of iliohypogastric nerve, ilioinguinal nerve, and genital branch of genitofemoral nerve was 87.97%（139/158）, 82.28%（130/158）, and 34.18%（54/158）, respectively. The postoperative complication rate was 5.06%（8/158）, in which subcutaneous hydrops 5 cases, scrotal hematoma 2 cases, and wound infection 1 case, all recovered by conservative management. There was not inguinal hernia recurrence in 12 months of follow-up. In 1 month after operation, there were 63（39.87%） patients suffered from mild pain and 34（21.52%） patients suffered from moderate pain in inguinal region, there was no patient with severe pain, the mean pain score was 0.83. The incidence of chronic groin pain in 6 months was 5.06% （8/158）, in which 7（4.43%） patients suffered from mild pain, and 1（1/158） patient suffered from moderate pain. In 12 months, only 4（2.53%） patients still experience occasional pain or discomfort, the mean pain score was 0.03. Multinomial logistic regression analysis indicated that neurectomy had no influence on postoperative pain（P＞0.05）and non-identification of ilioinguinal nerve was a risk factor for early（1 month） postoperative moderate pain（OR=3.373, P=0.030）. Conclusions Standard surgical procedure acted according to the Lichtenstein guidelines and handling inguinal nerves correctly can result in low incidence of chronic pain after operation, and can make the patients have a better quality of life.
Objective To evaluate the clinical effect of Easy Prosthesis D-10 on open preperitoneal groin tension-free hernioplasty. Methods The operative time, operation-correlated complications, hospital stay and recent follow-up findings of 63 patients underwent preperitoneal groin tension-free hernioplasty were analyzed from October 2006 to April 2008. Results No case died in perioperative period. The average operative time was (47.6±10.5) minutes. None of incision infection and scrotal hydrocele occurred. The average hospital stay was (7.7±2.1) days. During follow-up period of 6 to 24 months, no recurrence, chronic pain and foreign body sensation were found. Conclusion The open preperioneal groin tension-free hernioplasty by Easy Prosthesis D-10 is safe and reliable, especially for the inguinal hernia with large hernia ring or defect of transversalis fascia and recurrent hernia.
Objective To study the advances in clinical application of hernioplasty by high molecular material. Methods The literature in the recent years on the advances of hernioplasty by high molecular material was reviewed. Results At present time many operative techniques of hernioplasty by high molecular material have been developed. The representative techniques were ①Rives-Stoppa′s mesh inlay hernioplasty; ②Lichtenstein′s tesion-free herniorrhaphy; ③mesh plug hernioplasty; ④Gilbert′s sutureless hernioplasty; ⑤laparoscopic inguinal hernioplasty. The reparing high molecular material was divided into absorbable and unabsorbable material, the former included polyglycolic-acid and polyglaction, the later consists of polypropylene polyester and expanded polytetrafluoroethylene.Conclusion The clinical application of henioplasty by high molecular material is increasing. According to the hernia type and patient condition, excellent outcome will be achieved by the application of proper repairing method and repair material.
Objective To explore surgical technique and clinical outcome of transabdominal preperitoneal hernia repair (TAPP) and totally extraperitoneal hernia repair (TEP) in inguinal hernia repair. Methods 〗The clinical data of 23 patients underwent laparoscopic herniorrhaphy were retrospectively analyzed. Nine patients were underwent TAPP, and 14 patients underwent TEP. Results 〗None of patients was changed to open operation. Only one patient of TEP was changed to TAPP. Average operative time was (82.1±40.6) min. Blood loss was (5.7±3.0) ml. Disruption of peritoneum happened to 2 patients underwent TEP. The rate of postoperative complications was 21.7% (5/23), which included serum swelling (1 case), scrotal emphysema (2 cases), transient neurapraxia in the area of repair (1 case) and urinary retention (1 case). No chronic pain, foreign body sensation and infection were found. Average hospitalization after operation was (4.3±0.9) d. No recurrence was observed during a follow-up period of 1-15 months. Conclusion 〗Laparoscope herniorrhaphy is safe due to lower recurrence and complications. It also has the advantages of slight pain and rapid recovery.
Objective To evaluate the clinical application of the different operative approaches of the laparoscopicrepair of inguinal hernia and provide a more rational and scientific choice for the surgeon. Methods The strict inclusion and exclusion criteria were set up. All the randomized controlled trials （RCT） about laparoscopic transabdominal preperi-toneal （TAPP） and totally extraperitoneal （TEP） approaches of laparoscopic inguinal hernia repair were collected. Meta an-alysis was performed according to the recommendation by the Cochrane handbook. Results Seven RCTs including 552 patients were analyzed， who were divided into TAPP group （n=302） and TEP group （n=250）. Compared with TAPP group， there were no significant differences of the operation time〔WMD=8.49， 95% CI （-1.37， 18.35）， P=0.09〕， postoperative hospitalization〔SMD=0.11， 95% CI （-0.12， 0.34）， P=0.34〕， postoperative recurrence rate 〔OR=1.37， 95% CI （0.36， 5.20）， P=0.64〕， and complications （incision infection， urinary retention） 〔Incision infection：OR=4.27， 95% CI （0.85， 21.57）， P=0.08；Urinary retention：OR=0.61， 95% CI （0.21， 1.78）， P=0.36〕in the TEP group. But the postoperative 24 h pain in the TEP group was significantly milder than that in the TAPP group 〔WMD=0.72， 95% CI （0.58， 0.87）， P＜0.000 01〕. Conclusions The currently available evidence shows that postoperative 24 h pain in the TEP group is more milder than that in the TAPP group. The time of the operation， postoperative hospitalization， postoperative recurrence， and complications are no significant differences between TAPP group and TEP group. Large-scale， high-quality RCTs are still needed to confirm or refuse the available evidence.
Objective To compare the feasibility， safety， and efficiency of laparoscopic total extraperitoneal （TEP）hernia repair surgery and laparoscopic transabdominal preperitoneal （TAPP） hernia repair surgery. Methods The clinical data of 95 patients with inguinal hernia who underwent laparoscopic TEP hernia repair surgery （TEP group） and TAPP hernia repair surgery （TAPP group） from Mar. 2010 to Oct. 2013 in our hospital were retrospectively analyzed， and clinical parameters including operation time， intraoperative blood loss， postoperative hospital stay， postoperative comp-lication， and operation cost of 2 groups were compared. Results All the procedures were successful， none of them was converted to open surgery. There was no significant difference between TEP group and TAPP group when considering operation time 〔（65±16） min vs.（68±17） min〕， intraoperative blood loss 〔（7.0±1.2） mL vs. （8.0±1.4） mL〕， visual pain analogue scale 〔（2.0±1.1） score vs. （1.8±1.1） score〕， postoperative hospital stay 〔（3.1±1.4） d vs. （3.3±1.2） d〕，and time to release to regular activities 〔（4.2±1.0） d vs. （4.5±1.2） d〕， P＞0.05. But the operation cost of TEP group was significantly lower than that of TAPP group 〔（8 033±536） yuan vs. （9 632±643） yuan， P=0.007〕. There were 6 atients （6.3%， 6/95） suffered complications， 3 cases in TEP group and 3 cases in TAPP group， including 3 cases of seroma or hematoma in scrotum， 1 case of transient neurapraxia， and 3 cases of urinary retention. There was no signi-ficant difference in incidence rate of postoperative complication between the 2 groups （P=1.000）. All patients were followed-up for 1-35 months 〔（20.0±10.2） months〕 without recurrence and chronic pain. Conclusions TEP and TAPP hernia repair surgery are feasible， safe， effective， and minimally invasive technique for inguinal hernioplasty. There are advantages and disadvantages of both TAPP and TEP hernia repair surgery， but there is no statistically significant difference regarding intraoperative and postoperative complications.
