Single incision laparoscopic totally extraperitoneal inguinal hernia repair

Aims

Various single incision laparoscopic surgeries (SILS) and natural orifice transluminal endoscopic surgeries (NOTES) have been reported recently. Herein we performed SILS for totally extraperitoneal inguinal hernia repair (TEP) on three cases.

Cases

Three males of 72, 49, and 73?years old with the diagnoses of bilateral primary inguinal hernia underwent single incision TEP. The operative steps of single incision TEP are very similar to those of a traditional laparoscopic TEP. The difference between them is a 2?cm infraumbilical incision for the placement of three (5?mm) trocars in single incision TEP. We preferred to use a 30° 5?mm laparoscope with some routine laparoscopic instruments during the surgical procedure. All the hernia defects were repaired with VyproII of 15?×?10?cm (Ethicon, NJ, USA). The operations took 32, 26, and 65?min, respectively, with no obvious inconvenience.

Results

All three patients were discharged on the second postoperative day uneventfully. The postoperative follow-up showed no recurrence in the three patients up to now.

Conclusion

The single incision TEP using an access port device is safe and feasible. Meanwhile SILS may reduce medical costs and complication rates through practice and improvement of SILS instruments.

Learning curve for laparoscopic totally extraperitoneal repair of inguinal hernia

Background

Laparoscopic totally extraperitoneal (TEP) repair has been accepted as a popular procedure for inguinal hernia repair, but surgeons still encounter technical difficulties owing to unfamiliar pelvic anatomy and limited working space. We sought to estimate the learning curve for laparoscopic TEP repair without supervision.

Methods

We retrospectively analyzed the medical records of patients scheduled for laparoscopic TEP repair of an inguinal hernia from December 2000 to October 2007.

Results

We reviewed medical records for 700 patients. The cases were divided into 8 groups: 20 patients each in groups I–V and 200 patients each in groups VI–VIII. No significant difference in demographic characteristics was identified among the groups. The mean duration of surgery significantly decreased (p < 0.001) in relation to experience; it reached a plateau of less than 30 minutes (mean 28 min) after 60 cases. The mean length of stay in hospital was 0.97 days, reaching a plateau after 20 cases. Six patients were converted to other techniques: 1 patient each in groups III and VIII and 4 patients in group VII. Three recurrences were detected; however, 2 were excluded because the patient had bilateral inguinal hernias.

Conclusion

We estimate the learning curve for laparoscopic TEP repair is 60 cases for a beginner surgeon. The presence of an experienced supervisor during the first 60 cases can help prevent unnecessary complications and shorten the duration of surgery.

Prospective audit of laparoscopic totally extraperitoneal inguinal hernia repair

BACKGROUND: This article reports the results of a multicenter prospective audit of totally extraperitoneal (TEP) inguinal hernia repair conducted by the Swiss Association for Laparoscopic and Thoracoscopic Surgery (SALTC) from May 1995 to August 1996. METHODS: At 29 Swiss centers 1,605 inguinal hernia repairs were performed in 1,186 patients. Half of the repairs were performed by operators whose experience consisted of fewer than 51 procedures. Patients were followed up for 1 year. RESULTS: Bilateral repairs were performed in 35% of the patients, and 15% of all repairs were for recurrent hernia. Conversion rates to the transabdominal preperitoneal (TAPP) technique and open surgery were 1.8% and 1.6%, respectively. Main postoperative complications were hematoma and urinary retention. At 3 months, seroma was more frequent with slit prosthesis. The recurrence rate was 0.6% at 3 months and 1.6% at 1 year, not depending on the type of implant. The rate for recurrent hernias did not differ from that for primary repairs. CONCLUSIONS: Total extraperitoneal (TEP) repair can be performed with low morbidity and a high level of patient satisfaction. The effects of the learning curve are not to be neglected. The 1-year recurrence rate is 1.6%. Published data on TEP suggest that late recurrences may be less frequent than after open repair.     

Unusual complications of laparoscopic totally extraperitoneal inguinal hernia repair

Although complications of laparoscopic totally extraperitoneal inguinal hernia repairs are well documented, the development of pneumothorax, pneumomediastinum and subcutaneous emphysema is rarely reported. The authors' experience with a 23-year-old man who developed intraoperative bilateral pneumothoraces and cervical subcutaneous emphysema during a laparoscopic totally extraperitoneal inguinal hernia repair prompted a MEDLINE literature review. Seven similar cases were found in which the patients developed pneumothorax, pneumomediastinum and/or subcutaneous emphysema following laparoscopic hernioplasty. An intercostal catheter was inserted in two out of the seven patients only. Numerous hypotheses were proposed for the development of these complications. Several authors felt that the duration of the procedure and preperitoneal insufflation pressures are related to the development of these complications. These potentially lethal complications must be diagnosed and managed promptly.

目的:探讨腹腔镜全腹膜外疝修补术(totally extraperitoneal,TEP)治疗男性双侧腹股沟斜疝的临床疗效。方法:回顾分析2010年1月至2012年6月收治的162例双侧腹股沟斜疝男性患者的临床资料,分别行TEP(腔镜组)与Lichtenstein无张力疝修补术(开放组)。对比两组患者手术时间、住院时间、恢复正常活动时间、术后并发症等。结果:与开放组相比,腔镜组患者年龄、BMI、术前ASA分级、疝分型及随访时间差异均无统计学意义(P>0.05),但手术时间较长[(54.0±6.4)min vs.(45.0±4.2)min,P<0.001],术后恢复正常活动时间显著缩短[(10.0±1.6)d vs.(12.2±2.0)d,P=0.001],并发症发生率显著降低(7.1%vs.18.9%,P=0.046),术后住院时间两组差异无统计学意义[(4.4±1.3)d vs.(4.9±1.5)d,P=0.311]。结论:与开放手术相比,TEP治疗男性双侧腹股沟斜疝具有术后康复快、并发症发生率低的优点,值得推广。     

Intestinal obstruction after totally extraperitoneal laparoscopic inguinal hernia repair.

Laparoscopic hernia repair is a frequently performed operation. Although it has many advantages over open inguinal hernia repair, laparoscopic surgery is not without complications. Small bowel obstruction is a complication unique to laparoscopic repair of inguinal hernias. It is reported following transabdominal preperitoneal repairs. We present a case of small bowel incarceration through a peritoneal defect after a totally extraperitoneal inguinal hernia repair. Techniques to avoid this complication are presented. The literature is reviewed.

SIADH following laparoscopic (totally extraperitoneal) inguinal hernia repair

Syndrome of inappropriate secretion of antidiuretic hormone (SIADH) is recognised to occur after cardiac and traditional open abdominal surgery. However, SIADH after laparoscopic surgery is not well documented in the literature. We report a case of SIADH after laparoscopic (totally extraperitoneal) inguinal hernia repair in an elderly man.

The totally extraperitoneal laparoscopic hernia repair

Background: The totally extraperitoneal laparoscopic hernia repair has become our procedure of choice to manage inguinal hernia in adult patients since March 1993. This technique was developed in an attempt to diminish post-operative pain, shorten the convalescence period and equal the recurrence figures of the classical tension-free repair. Methods: A complete extraperitoneal dissection is performed. A large Marlex prosthesis (15×15 cm) is placed and covers all potential defects. Results: A consecutive series of 195 hernias in 158 patients is proposed. The minimum follow-up in our series is at least 6 months. Morbidity is low and so far, no recurrences have been seen. Conclusions: The totally extraperitoneal laparoscopic approach for repairing inguinal hernia should have a promising future, because the same principles as the classical tension-free repair are followed. Preliminary results are promising. Further studies, even randomized prospective trials and fair reports of complications, will determine the future of laparoscopic hernia surgery.
