Pure tissue repairs: a timely and critical revival.

"The majority of hernias can be satisfactorily repaired by using the tissues at hand. The use of mesh prosthesis should be restricted to those few hernias in which tension or lack of good fascial structures prevents a secure primary repair. This group includes large direct inguinal hernias and incisional hernias in which the defect is too large to close primarily without undue tension. Most recurrent hernias, because of this factor are best repaired with mesh prosthesis". These words, penned in 1960 by Francis Usher have reconfirmed what had been a mantra of the Shouldice Hospital (Usher in 81:847-854, 1960). The Shouldice Hospital has specialized in the treatment of abdominal wall hernias since 1945. It has, since its beginning, insisted on the fact that a thorough knowledge of anatomy coupled with large volumes of surgical cases would lead to unparalleled expertise. It was Cicero who taught us that "Practice, not intelligence or dexterity, will win the day"! Since the seminal contribution of Bassini (1844-1924), there have been no less than 80 procedures imitating his inguinal herniorrhaphy and much more since the introduction of mesh and mesh devices (Iason in Hernia. The Blakiston Company, Philadelphia, pp 475-604, 1940). All have failed to some extent and it appears that the common denominator for these failures was the inability to understand the importance of entering the preperitoneal space. Only Shouldice and McVay (Lotheissen, Narath) realized the shortcoming and have continued to thrive as a successful procedure. Entering the preperitoneal space eliminates any temptation to plicate the posterior inguinal wall, a layer normally deficient in direct inguinal hernias, but it also allows the identification of muscle layers rectus, transversus and internal oblique muscles which will go to reconstruct the posterior inguinal wall, without tension as reported by Schumpelick (Junge in 7(1):17-20, 2003).

Theodor Billroth's vision and Karl Ziegler's action: commemoration of the 40th day of death and the 50th anniversary of conferment of Nobel Prize for Chemistry of Karl Ziegler.

Alloplastic materials are broadly used in modern surgery. Until the middle of the 20th century, metal materials and especially silver were used because of their antimicrobial properties. With the development of a new catalytic process for the production of high-density polyethylene and polypropylene materials, a new era of prosthesis was introduced. These polymers are integral part of our everyday operations surgery, especially in hernia repair. The famous surgeon Billroth mentioned to his pupil Czerny in 1878: "If we could artificially produce tissues of the density and toughness of fascia and tendon, the secret of the radical cure of hernia would be discovered". The polypropylene developed by Karl Ziegler gave the surgeon a material for daily practice, which in its properties (nearly) achieved Billroth's initial vision. In 1963 the Nobel Prize for Chemistry was awarded to Karl Ziegler and Giulio Natta in Stockholm. Furthermore, August 11, 2013 will be the 40th anniversary of Karl Ziegler's death. This manuscript honors both days.

Degradation, infection and heat effects on polypropylene mesh for pelvic implantation: what was known and when it was known.

Many properties of polypropylene mesh that are causative in producing the complications that our patients are experiencing were published in the literature prior to the marketing of most currently used mesh configurations and mesh kits. These factors were not sufficiently taken into account prior to the sale of these products for use in patients. This report indicates when this information was available to both mesh kit manufacturers and the Food and Drug Administration.

The contributions of Usher and others to the elimination of tension from groin herniorrhaphy.

Relaxing incisions (Wolfler 1892) were eventually shown (Read and McLeod, 1981) to reduce but not eliminate wound tension after sutured herniorrhaphy of the groin. Reinforcing prosthetics became widely shunned because of morbidity until Usher et al (1958) introduced polyethylene, then polypropylene mesh (1963) for preperitoneal tensionless repair of large defects. Excellent long-term results were obtained, with his technique, by Collier and Griswold (1967). Patt (1967) envisaged its application to primary hernia. Reis (1899) introduced early ambulation. However, it was not until Leithauser (1943), Blodgett (1946), and others showed immediate rising accelerated wound healing and reduced complications that Farquharson (1955) began outpatient hernioplasty (in 1950) under local anesthesia (Cushing 1900). Bellis (1964) followed, performing tensionless repair in 25%. Rodriguez and Phillips (1967) described office herniorrhaphy, 30% undergoing polypropylene mesh coverage without tension. Lichtenstein (1970) reported mesh onlay reinforcement for sutured repair of large defects, discharge was within 24 hours. Martin et al (1982) began (in 1972) to treat all inguinal herniation in adults with polypropylene mesh "to avoid recurrences". Newman did likewise, using tension-free placement (Rodriguez et al) in the subaponeurotic plane. Encountering resistance to publication ("real surgeons don't use mesh") he, in 1980, asked Lichtenstein to publish and popularize the technique. Kelly (1898) introduced plug prosthestic repair of femoral herniation. Drainer and Reid (1972) used polypropylene mesh from below under local anesthesia. Lichtenstein and Shore followed, treating recurrent inguinal defects similarly. Gilbert (1989) applied the technique to indirect herniae. Usher and others deserve recognition for their contributions to the elimination of tension from herniorrhaphy.
