Persistent scrotal swelling after laparoscopic inguinal hernia repair: “Omentaloma of the scrotum”

Complete removal of all the contents of a hernial sac is crucial in laparoscopic inguinal hernia repair. We report a case who underwent transabdominal preperitoneal repair for a complete, irreducible inguinal hernia. He had persistent scrotal swelling and new onset scrotal pain post-surgery. Ultrasonography of the scrotum revealed a well-defined hypoechoic scrotal lesion. A magnetic resonance imaging revealed a fat-containing mass lesion, hypointense on T2 fat-saturated image. He underwent exploration of the scrotum and a well-encapsulated mass was excised. The histopathological evaluation revealed a well-encapsulated structure comprising of lobules of fibroadipose tissue with foci of chronic inflammation and foamy histiocytes likely retained omentum from previous surgery. His scrotal pain disappeared post-excision. A missed retained omentum in the hernial sac causes considerable anxiety to patients and diagnostic and therapeutic dilemmas for the treating surgeon. We coined the term “omentaloma of the scrotum” for such a lesion.     

Development of a novel training system for laparoscopic inguinal hernia repair

Background: Laparoscopic inguinal hernia repair is considered technically difficult. Although a simulation-based curriculum has been developed to help trainees, access to simulation training outside North America is limited. This study aimed to develop an educational system for the transabdominal preperitoneal (TAPP) approach based on the TAPP checklist, an assessment tool we had developed and validated earlier.

Material and methods: Consensus within the TAPP education working group consisting of local TAPP experts, hernia experts and a surgical educator to develop educational tools and the educational system based on the TAPP checklist. The system was piloted in several institutes, and participants were surveyed on its efficacy.

Results: We systematically developed an educational video and training manual explaining each item of the TAPP checklist and conveying basic knowledge of the procedure. We integrated the training tool with evaluation and feedback to develop an educational system. In a pilot study, seven trainees at five hospitals were trained using this system and found it very useful for mastering the TAPP procedure.

Conclusions: We have developed a training system for TAPP procedure and successfully implemented it in several hospitals. Further research will focus on the educational value of this tool.     

腹腔镜下两种腹股沟疝修补术治疗腹股沟疝临床疗效分析

目的探讨腹腔镜下两种腹股沟疝修补术治疗腹股沟疝的有效性及安全性。方法回顾性分析2010年3月至2012年8月施行腹腔镜下完全腹膜外腹股沟疝修补术(TEP)的38例成人腹股沟疝患者的临床资料,并与同期施行经腹腔镜腹膜前修补术(TAPP)进行比较分析。结果两组患者住院时间、住院费用、术后下床时间及并发症的发病率均无显著差异(P>0.05);但是手术时间TAPP组长于TEP组,两组比较差异具有统计学意义(P<0.05);TAPP组术后复发2例,TEP组无复发。结论 TAPP和TEP均是治疗成人腹股沟疝的有效方法,但TEP手术时间短,安全性更高,值得临床推广应用。     

腹腔镜腹股沟疝修补术后复发与并发症分析

探讨腹腔镜腹股沟疝修补术术后复发与并发症的原因。方法:回顾性分析1993年10月至2001年10月行腹腔镜腹股沟疝修补术的52例(67例次)病人的临床资料,其中经腹腹膜前补片植入术37例(48例次),经腹膜外补片植入术15例(19例次)。随访时间8～24个月(中位时间18个月)结果:本组腹腔镜腹股沟疝修补术术后复发率为4.5%(3/67);前3位并发症依次为阴囊气肿、暂时性神经感觉异常和阴囊血清肿,发生率分别为43.3%、17.9%和9.0%;手术时间为68.6min±40.5min,术后住院天数为7.1d±2.0d。结论:腹腔镜腹股沟疝修补术是安全的无张力手术,降低复发和并发症的关键在于熟悉腹膜前间隙的解剖。     

Laparoscopic hernia repair—TAPP or/and TEP?

Background Of various endoscopic hernia repair procedures, TAPP and TEP have been selected for routine use.Methods Results from Medline research were analysed.Results There is a similar risk for postoperative morbidity for both techniques. The recurrence rate in large single-centre series is between 0% and 3.4%. There were numerous indications for both procedures, whereby a transperitoneal TAPP can also be applied in cases of previous preperitoneal operations.Conclusion Randomised trials comparing both methods of hernia repair are lacking. Seven non-randomised studies showed no differences in recurrence rate and morbidity. In general the learning curve for is shorter in favour of TAPP repair.     

腹腔镜完全腹膜外腹股沟疝修补术治疗腹股沟疝的效果探讨

目的 研究腹腔镜完全腹膜外腹股沟疝修补术治疗腹股沟疝的效果.方法 整群选取该院2013年3—11月收治的90例腹股沟疝患者,按照手术方法不同,抽签随机分为经腹腔膜前修补术(TAPP)组和完全腹膜外疝修补术(TEP)组,每组各45例. 观察两组手术时间、术中出血量、恢复正常活动时间以及术后24 h的疼痛程度评分(VAS). 结果 TEP组手术时间(61.5±10.8)min、手术费用(7210.0±1200.0)元相较对TAPP组(72.4±12.4)min、(7842.0±1640.0)元显著较少,差异有统计学意义(P<0.05);TEP患者术后24hVAS(2.64±0.28)分相较TAPP(3.06±0.18)分显著较低,差异有统计学意义(P<0.05). 结论 TEP修补术治疗腹股沟疝能有效缩短手术时间,节约成本,减轻患者痛苦,具有较高的临床价值.     

Development of scar-less laparoscopic hernia repair (TAPP-252) facilitated by new 2mm instruments

Introduction: To minimize the invasiveness of laparoscopic transabdominal preperitoneal hernia repair (TAPP) for the treatment of adult inguinal hernia, we developed a new operative technique with the use of only one 5?mm port and two 2?mm punctures (TAPP-252).

Material and methods: To facilitate TAPP-252, we developed seven kinds of new 2?mm instruments, including grasping forceps, hook shaped electrode, mesh pusher, needle driver, scissors, laparoscope and port.

Results: TAPP-252 was stably performed in 35 patients with minimal abdominal wall destruction and excellent cosmetic result without any recurrence or morbidity.

Conclusions: The newly developed 2?mm devices showed sufficient performance and durability in TAPP-252. Further investigation is necessary to assess durability and long-term outcomes.
