Abstract：

Objective To evaluate low-weight mesh for tension-free repair of inguinal hernia in the elders. Methods 120 old patients ( age at 60 -97 years) underwent tension-free repair of inguinal hernia by using low-weight mesh. The early complications, time of up and about, hospital stay, postoperative chronic pain,foreign body feelings and hernia recurrence were analyzed. Results The operations were successful in all cases and the average time of operation was (43 ± 12 ) min. 9 cases suffered from edema of the scrotum, 5 cases suffered urine retention, 4 cases suffered from incision hematoma. The average time of outof-bed was ( 17.4 ± 1.8 ) h, the average hospital days was ( 7.4 ± 1.9) d. However, there were 1.7%(2/120) patients suffering from slight chronic pain and 9. 1% (11/120) patients complaining foreign body feelings. There was no recurrence after follow-up for 6 to 48 months. Conclusions The clinical application of low-weight mesh for tension-free repair of inguinal hernia in old age is safe and effective, with an additional advantage of low occurrence of chronic pain and foreign body feelings.     

Decision analysis model of incisional hernia after open abdominal surgery

Background The incidence rate of incisional hernias after open surgery has been reported to be higher than that of port site hernias after laparoscopic surgery. No studies have compared the costs for the health care system in treating those two types of hernia. Methods A systematic review was conducted to obtain the baseline data, and a decision analysis model was created to simulate the occurrence and recurrence of incisional and port site hernias. Results The overall risk of having incisional hernias was eight-times higher than that of having port site hernias (7.4% vs 0.9%). A cost savings of ￡93 per patient can be generated for the health care system in the UK. Similar results were obtained for Germany, Italy and France. Conclusions The additional treatment costs for incisional hernia should be taken into account when the costs of a surgery performed by open approach are compared with by laparoscopy.

Abstract：

Objective To evaluate medical chemistry adhesive in tension-free herniorrhaphy for inguinal hernia. Methods In this study, 100 patients with primary unilateral inguinal hernia were assigned to study group ( n = 50) and control group ( n = 50) during Jun. 2009 and Dec. 2009. Medical chemistry adhesive (n-butyl-2-cyanoacrylate, NBCA) was used in Lichtenstein tension-free hernia repair in study group and suture procedure was used in control group. Patient demographics, operation time,postoperative length of stay, visual analogue scale ( VAS ) score 24 hours after surgery, incidence of postoperative chronic pain and hematoma, recurrence rate, and other complications were compared between the two groups. Results The duration of follow-up ranged from 12 months to 18 months. There were no recurrences or wound infection in the two groups. In study group, no patient complained of chronic pain postoperatively, whereas in the control group, 6 patients ( 12% ) had a significant chronic pain. In study group, 2 patients (4%) had local hematoma after operation, whereas there were 8 ( 16% ) in the control group ( P ＜ 0. 05 ). There were no significant differences between the 2 groups in postoperative length of stay ( P ＞ 0. 05 ), but the operation time and postoperative VAS score in study group ( 38 ± 5 min and 2. 5 ± 0. 6)were lower than in the control group (42 ± 5 min and 2. 8 ± 0. 8 ), ( P ＜ 0. 05 ). Conclusions Application of medical chemistry adhesive in tension-free herniorrhaphy for inguinal hernia is associated with less postoperative pain, lower incidence of hematoma, less postoperative chronic pain and shorter operation time.

Abstract：

Objective To review the clinical experience of diagnosis and treatment of the congenital diaphragmatic hernia in newborn infants. Methods Thirty-three neonates were diagnosed having congenital diaphragmatic hernia in our hospital from Jan. 1,2004 to Sept. 30, 2009. The clinical data was retrospectively reviewed. Results 21 cases were treated surgically and 17 survived, while 4 cases died. The main cause of death was congenital pulmonary dysplasia. Another 12 cases refused to accept surgical treatment and they all died, one died shortly after he was born. Four cases who had been diagnosed by prenatal ultrasonography were survived. Conclusion The mortality of congenital diaphragmatic hernia in neonates was still high. Prenatal diagnosis of the congenital diaphragmatic hernia is very important and the cooperation between the obstetrics, neonatology and cardiothoracic surgery will improve the survival rate of congenital diaphragmatic hernia in newborn infants.

Abstract：

Objective To evaluate the efficacy of perioperative antibiotic prophylaxis for tension-free repair of inguinal hernia. Methods A randomized, prospective double-blind control trial was performed to evaluate the efficacy of perioperative antibiotic prophylaxis for tension-free mesh repair in 180 cases of inguinal hernia from March 2007 to March 2008. Intravenous cefuroxime ( 1.5 g ) was given immediately before the surgery in two groups followed by postoperative administration of cefuroxime 1.5 g twice a day for 3 days in test group compared with NS infusion in the control group. Postoperatively 16 patients (8. 89 per cent) could not be contacted at any point, giving a response rate of91. 11%. The total number of subjects for per- protocol (PP) analysis was 180, 84 cases in test group and 80 cases in control group. Results Complete data were available for 164 patients, 3 ( 1.83 per cent) developed surgical site infection (SSI) including 2 cases of surgical site infection in test group and 1 case of superficial incision surgical site infection in control group. The differences were not statistically significant. The time to follow up was 12 -29 months, the mean follow up time in test group was (15.6 ±2.2) months and (18 ±3)months in control group respectively. 93.33% patients in test group were followed up and 88. 89% patients in control group. There were not hernia recurrence and side effect of antibiotics reported in the two groups.Conclusions To prevent SSI, it is necessary to use preoperative antibiotics prophylaxis just one time for inguinal hernia repair.     

Complete recovery after the removal of an ectopic testicle in a case of primary reninism and retroperitoneal hemangioma

A 32-year-old man recovered completely from hypokalemic hypertension that had been caused by primary reninism after the ablation of an ectopic left testis, epididymis and ductus deferens. For several years, severe hypertension has been resistant to treatment, even the concurrent administration of up to seven antihypertensive agents. In this case, cryptorchidism was associated with an indirect inguinal hernia and an open peritoneo-vaginal process on both sides, aplasia of the posterior wall of the inguinal canal on the right side, an umbilical hernia, and a retroperitoneal tendrillar hemangioma. （Asian J Androl 2006 Mar; 8： 247-250）     

Use of bovine pericardium graft for abdominal wall reconstruction in contaminated fields

AIM:To employ, in such conditions, a biological graft such as bovine pericardium that offers resistance to infection. METHODS:In our surgical department, from January 2006 to June 2010, 48 patients underwent abdominal wall reconstruction using acellular bovine pericardium; of these 34 patients had a contaminated wound due to diffuse peritonitis (complicated diverticulitis, bowel perforation, intestinal infarction, strangled hernia, etc. ) and 14 patients had hernia relapse on infected synthetic mesh. RESULTS: In our series, one patient died of multiorgan failure 3 d after surgery. After placement of the pericardium mesh four cases of hernia relapse occurred. CONCLUSION: Recurrence rate is similar to that of prosthetic mesh repair and the application of acellular bovine pericardium (Tutomesh , Tutogen Medical Gmbh Germany) is moreover a safe and feasible option thatcan be employed to manage complicated abdominal wall defects where prosthetic mesh is unsuitable.     

Cost-effective laparoscopic TEP inguinal hernia repair: the Portsmouth technique

NICE (UK) has not recommended unilateral primary laparoscopic inguinal hernia repair because of its expense. A two-port technique without balloon inflator or routine tacking was developed, which helped reduce costs to just ￡35 more than day-case open hernia repair. Over a 6-month period, 40 patients underwent 60 TEP repairs with a 6-month follow up. Zero degree laparoscope (10 mm) and blunt graspers (5 mm) created the pre-peritoneal space, identified landmarks and completed the dissection. Trimmed 15×15 cm mesh was placed over each defect. Operating times for unilateral and bilateral hernias for consultants and supervised trainees were 30*, 42.5* and 40*, 55* min (*: Median) respectively. Verbal rating pain scores at 24 and 72 h were 1* (0–3) and 0* (0–2) respectively. Patients returned to activity, driving and work in 5*, 7* and 14* days respectively. Cost of laparoscopic hernia repair was calculated at ￡105. A two-port laparoscopic hernia repair can be performed effectively and safely, in reasonable time and at a low cost. These data support the use of this technique in primary unilateral inguinal hernia.

Concurrent radical retropubic prostatectomy and inguinal hernia repair through a modified Pfannenstiel incision

OBJECTIVE: To describe a technique for concurrent radical retropubic prostatectomy (RRP) and inguinal hernioplasty, using a modified Pfannenstiel incision. PATIENTS AND METHODS: RRP is usually done through a midline lower abdominal incision but some patients with localized prostate cancer have an inguinal hernia. Concurrent inguinal hernia repair at the time of RRP with the usual method is only possible by either a preperitoneal mesh repair or formal hernioplasty, requiring an additional incision(s). A 10-12 cm Pfannenstiel incision is made along the pubic hairline centred over the pubic symphysis, and a 'Y'-shaped incision in the rectus sheath. The rectus muscle is split vertically along the midline, followed by RRP. After removing the prostate and completing the anastomosis, the surgeon identifies the inguinal canal along the inferior and lateral aspect of the transverse incision and uses a formal tension-free hernioplasty with a 3 x 5 cm polypropylene mesh. We used this technique in fifteen concurrent inguinal hernioplasties (two bilateral hernias and thirteen unilateral) at the time of RRP, with no additional incisions, using the formal tension-free Lichtenstein technique. One patient with bilateral hernias had a right indirect inguinal hernia, and all the remaining men had a direct inguinal hernia. RESULTS: All patients were discharged 2 days after surgery, with no complications associated with the procedure and no recurrences; however, the follow-up was short (mean 5.5 months). CONCLUSION: A modified Pfannenstiel incision is ideal for concurrent RRP and inguinal hernioplasty, providing excellent exposure of the pelvic structures and allowing the surgeon to use a formal tension-free mesh hernioplasty through the same incision. Wound healing and cosmetic results are excellent.

Recurrent inguinal hernia due to mesh dissolution: two case reports

The recurrence of inguinal or other abdominal hernia due to Prolene polypropylene mesh dissolution has never been reported in the literature. This is a report of two cases of recurrent inguinal hernias after mesh hernioplasty, but, on exploration, no mesh was found.     

Preperitoneal prosthetic mesh hernioplasty during radical retropubic prostatectomy

PURPOSE: The number of radical retropubic prostatectomies performed in the United States has increased during the last decade. There are 5 to 10% of candidates for radical retropubic prostatectomy who have a detectable inguinal hernia on physical examination. Furthermore, recent data suggest that there is an increased incidence of inguinal hernia after radical retropubic prostatectomy. We evaluated the role of simultaneous inguinal hernioplasty during radical prostatectomy. MATERIALS AND METHODS: During 575 radical prostatectomy procedures from June 1991 to June 1997, 70 hernioplasties were performed in 48 patients. Retrospective chart review was performed for all men who underwent simultaneous hernia repair. Mean patient age was 60.9 years (range 43 to 73). Polypropylene or polyester fiber prostheses were used for mesh hernioplasty. All repairs were performed using a preperitoneal approach during radical retropubic prostatectomy. RESULTS: There were 35 hernioplasties performed without and 35 with mesh. Mean postoperative followup was 24 months (range 6 to 66). Of the hernias 71% were indirect and 29% were direct. No recurrence was detected after mesh hernioplasty, whereas 5 hernias (14%) recurred in the nonmesh group. In this group 2 men (4%) also had de novo hernias on the contralateral side during followup. All recurrent hernias were diagnosed within 1 year of the initial operation. No patient had wound infection, persistent neuralgia or ischemic orchitis. CONCLUSIONS: Simultaneous repair of inguinal hernias during radical retropubic prostatectomy is effective and technically feasible. There is convenient access to the preperitoneal space during radical retropubic prostatectomy and hernia repair adds only 5 to 10 minutes of operative time. Mesh repair appears to offer optimized results compared to the nonmesh technique. Despite the use of prosthetic material, no complications were attributable to its application during these genitourinary procedures.     

Inguinal hernia repair with polypropylene mesh during radical retropubic prostatectomy: an easy and practical approach

OBJECTIVE: To report the results of the simultaneous inguinal hernia repair during radical retropubic prostatectomy (RRP) with the preperitoneal tension-free Stoppa technique, using a polypropylene mesh. PATIENTS AND METHODS: During 855 consecutive RRPs, 40 (5%) patients (median age 66.9 years, range 52-81) with 49 inguinal hernias had a simultaneous inguinal hernioplasty. The RRP was performed according to the Walsh modified technique. After the prostate and seminal vesicles were removed and the urethrovesical anastomosis completed, a polypropylene mesh of maximum size 15 x 7.5 cm and a small slit on its medial side was then created and placed in the preperitoneal space, embracing the spermatic cord and covering the myopectinal orifice. Preoperative risk factors, e.g. constipation, pulmonary disease or urinary obstructive symptoms, were collected retrospectively from the files. Complications after surgery, including wound infection, pelvic collections, urinary fistula and recurrence of the hernia, were assessed. RESULTS: Preoperative risk factors for hernia development were identified in 23 (58%) patients; three had recurrent hernias. With a median 23.1 months of follow-up period two (4%) hernias recurred. There were no complications after surgery. CONCLUSION: Preperitoneal hernia repair with polypropylene mesh is safe, effective and practical. The procedure simultaneous with RRP gave a 96% success rate and with no significant increase in operating time or additional complications.

Ultrasound tissue modifications after polypropylene prosthesis apposition in inguinal hernia

Few studies have addressed the use of ultrasonography in the evaluation of abdominal hernia. In the present study ultrasonography was used to assess tissue modifications after apposition of a polypropylene prosthesis for inguinal hernia. Seventy-two patients submitted to calibrated inguinal hernioplasty (mesh and plugs) in local anaesthesia for inguinal hernia were studied by ultrasonography at 5 days, 1 and 3 months, and 1 year after the surgical intervention. The mesh presented as a small hyperechoic layer. In 50 patients (69.4%) a seroma was present above the mesh. The seroma was < 5 cc in 33 patients, between 5 and 10 cc in 6 patients, and > 10 cc in 11 patients. During the ultrasound examinations no recurrences were found and the mesh was not displaced. The seroma disappeared spontaneously between postoperative days 30 and 90 and was probably related to the size of the hernia and the number of plugs.     

善释疝环充填式补片在复发性腹股沟疝中的应用

目的总结应用善释网塞补片在疝环充填式无张力疝修补术治疗复发性腹股沟疝的临床疗效。方法回顾分析我院自2004年12月至2008年12月32例复发性腹股沟疝疝环充填式无张力疝修补术的临床资料。其中斜疝21例,直疝11例。全部病例均行疝环充填无张力修补术。结果术后发生尿潴留2例,阴襄水肿3例。随访6～24个月,全组无复发病例。结论应用国产善释网塞补片在疝环充填式无张力疝修补术治疗复发性腹股沟疝复发率低,手术创伤小、患者恢复快、术后并发症少,是目前治疗复发性腹股沟疝较理想的方法。     

Percutaneous endoscopic external ring (PEER) hernioplasty

This pilot study was conducted to determine if percutaneous endoscopic external ring (PEER) hernioplasty would be a viable alternative to the conventional and laparoscopic methods of tension-free repair. The procedure consists of (1) a 2.0–2.5-cm incision over the external inguinal ring to reach the emerging spermatic cord structures, and ligation and excision of the hernia sac and (2) insertion of an endoscope-attached retractor through the external ring, into the inguinal canal for visualization, dissection of posterior inguinal wall, and placement of mesh to complete tension-free repair. PEER hernioplasty was used to treat 48 patients with 60 primary hernias (bilateral in 12 patients) between January 1993 and December 1994. Median follow-up was 12 months and ranged from 5 to 22 months. All patients were discharged within 24 h after surgery except for one. All patients resumed their normal activity within 2–3 weeks. Only three complications were encountered (two scrotal hematomas and one inguinal seroma). To date, there has been recurrence of two hernias in one patient. We conclude that PEER hernioplasty is an effective method of repair of primary hernias that is less invasive than the conventional approach and both less invasive and more cost-effective than laparoscopic approaches.
