B-Myb, a repressed trans-activating protein

From April 1990 to November 1996, 313 inguinal and 14 femoral hernias were repaired in 295 subjects with a mean age of 74 years (66 to 97). Concomitant diseases increasing the operative risk were present in 206 subjects (70 per cent). A mesh repair was performed with "tension-free" or "plug" techniques in all but 23 inguinal and 2 femoral herniorrhaphies where the Bassini or the Shouldice procedures were adopted. Fifty-two inguinal hernias were recurrent, 11 emergency herniorrhaphies were performed for strangulation. Almost all operations (305), including 9 emergency herniorrhaphies, were carried out under local anaesthesia. There was no perioperative mortality. Acute intestinal bleeding occurred after surgery in a subject with colon diverticulosis. One urinary retention following emergency hernia repair under general anaesthesia and 2 following elective hernia repair under local anaesthesia in 2 subjects with hypertrophy of the prostate were observed. Some episodes of hypotension and/or bradycardia were observed either during or after surgery. Local complications following inguinal hernioplasty were 5 (1.5%) scrotal hematomas, 3 (0.9%) wound infections and 1 case (0.4%) of orchitis with atrophy after repair of a recurrent hernia. There were 1 recurrence after Bassini, 1 after Shouldice, and 1 (0.4%) after mesh inguinal hernioplasty. Using local anaesthesia and a mesh repair elective surgery of inguinal and femoral hernias can be safely and effectively performed in elderly patients. Consequently, early elective surgery should be recommended to avoid the risk of an emergency operation.     

Lichtenstein herniotomy

All standard methods of hernia repair involve suturing together tissues which are not normally in apposition. This violates the basic surgical principle that tissue must never be approximated under tension and accounts for an unacceptable number of failures. Total reinforcement of the inguinal floor with a sheet of suitable biomaterial and employment of a "tension-free" technique is a more effective approach. Since June 1984, 3250 primary inguinal hernias have been repaired at the Lichtenstein Hernia Institute by the open tension-free technique using Marlex mesh. All operations were performed under local anesthesia. Patients were discharged from the hospital within two or four hours after the operation. The patients were followed from one to 8 years by physician examination. The follow-up rate was 87%. There were four recurrences. The causes of recurrence and how to avoid them are discussed.     

Adaptation of a fiber-reinforced restorative system to the rehabilitation of endodontically treated teeth

OBJECTIVE: Review of international literature reveals eight reported cases of laparoscopic obturator hernia repair. Non-specific signs and symptoms make the diagnosis of an obturator hernia difficult. Laparoscopic intervention provides a minimally invasive method to simultaneously diagnose and repair these hernias. METHODS AND PROCEDURES: A 35 year old woman presented with lower abdominal pain, vaginal bleeding, and dyspareunia. During gynecological diagnostic laparoscopy, a pelvic floor hernia was suspected, and a general surgical evaluation was sought. At a subsequent laparoscopy, the diagnosis of a left direct inguinal and a right obturator hernia was made. Both were repaired laparoscopically with polypropylene mesh. RESULTS: At follow-up at one and six weeks postoperatively, the patient's complaints of pain had completely resolved. CONCLUSION: The diagnosis of obturator hernia is problematic. The usual presenting signs and symptoms are non-specific. Without conclusive historical or physical findings, laparoscopy is an excellent method for diagnosing obturator hernia. This entity, once diagnosed laparoscopically, can be repaired simultaneously via laparoscopic mesh technique.     

Perioperative transfusion, postoperative infection, and recurrence of head and neck cancer

BACKGROUND: Considering the high recurrence rate after conventional inguinal hernia repair, the totally preperitoneal endoscopic inguinal hernia repair has been used. METHODS: The present experience of the authors embraces 1085 patients with a total of 1717 inguinal hernias, including 200 recurrences. The operative technique is described with emphasis on pitfalls and tricks. RESULTS: Analysis of the data concerning the first 403 patients with 1 year complete follow-up reveals a mean (SEM) operating time of 42 (1.2) min for unilateral and 58 (1.0) min for bilateral hernia repair. Mean (SEM) postoperative hospital stay was 2 (0.04) days. Complication rates during and after operation were 0.3% and 3.3% respectively. The morbidity rate at 1 month after operation was 3.5%. The recurrence rate was 0.3% at 1-year follow-up. CONCLUSION: Totally preperitoneal endoscopic inguinal hernia repair is safe and reproducible for any type of primary or recurrent inguinal hernia, even in patients with previous subumbilical surgery or severe systemic disease. Careful follow-up is mandatory to assess the late recurrence rate.     

The Lichtenstein open "tension-free" mesh repair of inguinal hernias

All standard methods of hernia repair involve suturing together tissues which are not normally in apposition. This violates the basic surgical principle that tissue must never be approximated under tension and thus accounts for an unacceptable number of failures. A total reinforcement of the inguinal floor with a sheet of suitable biomaterial and the employment of a "tension-free" technique is a more effective approach. Since June of 1984, 4,000 primary inguinal hernias have been repaired on an outpatient basis and under local anesthesia at the Lichtenstein Hernia Institute by the open "tension-free" technique using Marlex mesh. The patients were followed from one to 11 years (mean of 5 years) by physician examination. The follow-up rate was 87%. There were four recurrences. The causes of recurrence and how to avoid them are discussed herein. Three of the recurrences occurred at the public tubercle and were caused by placing the mesh in juxtaposition to the tubercle. This error has since been corrected by overlapping the mesh at the public bone. One recurrence was caused by disruption of the lower edge of the mesh from the shelving margin of Poupart's ligament. The error here was the utilization of a patch that was too narrow and therefore under tension. It became apparent that a wider patch, fixed in place with an appropriate degree of taxity, was required.     

Preperitoneal prosthesis implantation in surgical management of recurrent inguinal hernia. Retrospective evaluation of our results 1989-1994

Recurrent inguinal hernia represents a great problem in surgery given the frequency of this operation, with a recurrence rate of 0.5-8%. Re-recurrence after repair without implantation of a prosthesis occurs in 1-23% of cases. We analyzed our results of patients with recurrent inguinal hernia, operated according to the method of Stoppa. Between 1989 and July 1994 there were 58 operations upon 55 patients with an average age of 65 years, 79% of whom had unilateral and 21% bilateral hernias. 89% of all patients underwent surgery because of a recurrent inguinal hernia. A Marlex mesh was used in 79% of the case. All patients were followed up (mean 35 months, minimum 12 months). Early complications consisted in one hematoma (1.7%), which had to be drained, as well as one early recurrence (1.7%). No infections were observed. The overall recurrence rate was 12%. However, 60% of all recurrences occurred in the few first years after introduction of this technique at our clinic; with growing number of operations and experience with Stoppa's technique, we obtained a recurrence rate of 6-7% per year. In our opinion, supported by the results of other studies, Stoppa's technique is a successful method in the treatment of recurrent inguinal hernia.     

Laparoscopic evaluation for a contralateral patent processus vaginalis: part III

OBJECTIVES: Between May 1, 1992 and August 1, 1996, 759 consecutive children younger than 10 years of age were evaluated and treated for known inguinal hernia. These children were participating in a prospective investigation of the potential role of diagnostic laparoscopy in the evaluation of the contralateral inguinal anatomy. The initial two series of data (parts I and II of this three-part series) were previously presented at the 1993 and 1995 American Academy of Pediatrics meetings. METHODS: Of 759 patients, 100 children were diagnosed with bilateral inguinal hernias and therefore did not undergo laparoscopy. Thirty-two patients did not undergo laparoscopic evaluation due to technical difficulties or complicated clinical situations. The patient's contralateral inguinal region was carefully examined under anesthesia, and predictions were made regarding the likelihood of contralateral patent processus vaginalis (CPPV). Six hundred twenty-seven children underwent diagnostic laparoscopy to confirm the presence or absence of CPPV. Laparoscopy was initially exclusively performed through the umbilicus prior to repair of the known hernia, but over the last 26 months, 250 children successfully underwent laparoscopy through the ipsilateral hernia sac. RESULTS: Of patients younger than 1 year of age, 114 were diagnosed with both a known unilateral hernia and CPPV, whereas 132 had a unilateral hernia only (46% versus 54%). Among children older than 1 year of age, 148 (39%) were diagnosed with unilateral hernia and CPPV, and 233 (61%) were diagnosed with a unilateral hernia alone. After examination under anesthesia, 233 of the 627 patients were suspected of having a CPPV, and 107 were confirmed at laparoscopy (46%). The remaining 394 patients were not believed to have a CPPV. Normal inguinal anatomy was confirmed in 234 patients (59%), but 160 patients were found at laparoscopy to have a CPPV (41%). CONCLUSIONS: A contralateral patent processus vaginalis may be present in a surprising number of young patients being evaluated for a known inguinal hernia. Laparoscopy can be performed without a separate incision when the ipsilateral hernia sac is of sufficient width to allow passage of the scope. Laparoscopy is the best method for evaluating the contralateral inguinal region, particularly in younger children, as it prevents unnecessary inguinal exploration and it decreases the risk that the child will later present with a clinical contralateral hernia.     

Colonoscopic findings in Crohn''s disease--reproducible, but of questionable benefit

Between January, 1991 and December, 1993, 208 subjects with monolateral and 19 with bilateral inguinal hernia were submitted to herniorrhaphy. Thirty-four were recurrent hernias. All but one bilateral hernias were treated at the same time. Eight cases were operated in emergency condition for acute strangulated hernia. Two-hundred and ten operations were performed under local, 17 under general and 1 under spinal anesthesia. Herniorrhaphy was performed in 14 cases with the Bassini and in 38 with the Shouldice technique. In 191 instances the "tension-free" and in 3 the "plug" techniques were adopted utilizing a polypropylene mesh. Following local anesthesia 13 episodes of bradycardia with hypotension were recorded during the operation and 4 in the early postop period. There were no general complications. Two elderly patients developed urinary retention following general anesthesia. Local complications included 6 (2.4%) cases of infection and 4 (1.6%) cases of hematoma of the wound, and 5 (2.0%) cases of edema with infiltration of the cord. Percentage of follow-up at 1, 2 and 3 years was 96, 95, and 93 percent respectively. Five recurrences were recorded: in 1 case following Bassini repair (7.6%), in 2 following Shouldice (5.6%), and in 2 following tension-free (1.5%). Local anesthesia has been confirmed to be well accepted by the patients, effective an safe, especially in the elderly patients with high operative risk. Similarly, the tension-free hernioplasty has been confirmed as a simple, easily reproducible technique, followed by less pain and disability as compared with other types of herniorrhaphies, and more effective mainly in the treatment of recurrent hernia.     

Surgical treatment of postop abdominal hernia in elderly and geriatric patients

The results were summarized on surgical treatment of 56 patients, ageing 60-85 years, for femoral hernia using two methods--according to Bassini and original one stipulated for femoral ring strengthening using implant made of poliuretane in hernial sac tunic fixed without tension to inguinal and public ligaments. Recurrence of hernia in the late follow-up period have occurred in 13.6% of patients operated on according to Bassini and was never observed after operation performed using original method.     

The features of contralateral manifestations after the repair of unilateral inguinal hernia

BACKGROUND/PURPOSE: Routine contralateral exploration in infants and children with unilateral clinical inguinal hernia is performed by many surgeons in a selected population of patients based on a presumed high incidence of patent processus vaginalis. Our purpose is to report the actual incidence of contralateral manifestations in infants and children after the repair of unilateral inguinal hernia. METHODS: From July 1985 through December 1995, 1,052 infants and children with unilateral inguinal hernia or hydrocele were treated in our hospital without contralateral exploration. Among them, 1,001 patients (95.2%) were followed up for 1 to 11 years to determine if contralateral hernia developed after unilateral inguinal herniorrhaphy. RESULTS: The overall incidence of contralateral hernia was 11.6% (116 of 1,001). In boys, the incidence was 13.1%, 13.7%, and 11.7% in those under 1 year, under 2 years of age, and in total, respectively. In girls, the incidence was 9.6%, 13.9%, 11.3%, in those under 1 year, under 5 years of age, and in total, respectively. The side of the initial repair did not influence the subsequent development of contralateral inguinal hernia. In children with hydrocele, the incidence of contralateral hernias was lower (7.6%). In girls with sliding hernias the contralateral occurrence was 12.5%. CONCLUSION: Given this low incidence of contralateral hernia after unilateral inguinal herniorrhaphy, the authors do not recommend contralateral exploration for infants and children with unilateral inguinal hernia.     

Chronic inguinal pain after transperitoneal mesh implantation. Case report of net shrinkage

The implantation of a mesh is an essential step in laparoscopic inguinal hernia surgery. We present the case of a 22-year-old man who developed an unspecific and refractory syndrome of inguinal pain after a TAPP procedure for a primary inguinal hernia. Repeated reoperation for removement of clips and nerve transection were unsuccessful. By a transinguinal approach, 18 months after the first operation we removed a preperitoneal Prolene mesh which had shrunk and folded to 30% of its original size. The problem of biocompatibility of meshes currently used in inguinal hernia surgery is discussed.     

Laparoscopic inguinal herniorrhaphy: the new gold standard of hernia repair?

The surgical treatment of the common inguinal hernia has been one of the most analyzed and debated topics in medicine. Recently, with the success of laparoscopic cholecystectomy, interest in minimally invasive surgical techniques has led to it's application for inguinal hernia repair. Current laparoscopic herniorrhaphies are based on the principles of conventional open preperitoneal repairs and are classified into two types: 1) transabdominal preperitoneal repair (TAPP) and 2) totally extraperitoneal repair (TEP). Common advantages to both techniques include a decrease in postoperative pain, earlier return to normal activity, and improved cosmesis. Both laparoscopic techniques have the disadvantage of requiring general or regional anesthesia and increased procedural costs. Lastly, there is a concern that laparoscopic hernia repair has not been around long enough to know the risk of late recurrences. Laparoscopic herniorrhaphy, however, is a viable alternative to standard open inguinal hernia repair.     

Follow-up after inguinal hernia repair. Questionnaire compared with physical examination: a prospective study in 299 patients

OBJECTIVE: To assess the value of a written questionnaire in the follow-up of patients after inguinal hernia repair. DESIGN: Prospective study. SETTING: University and two district hospitals. The Netherlands. SUBJECTS: 314 patients with 362 inguinal hernias. MAIN OUTCOME MEASURES: Correlation between answers to questionnaire and clinical examination in the diagnosis of recurrent hernias. RESULTS: 13/24 recurrences (54%) after a mean follow-up of 33 months with a follow-up rate of 93% were not diagnosed by the questionnaire. CONCLUSION: Follow-up after hernia repair must be by physical examination.     

The silent epidural abscess as a complication of acute otitis media in children

Vesical hernia is defines as a vesical shift associated to a direct or indirect inguinal hernia. It accounts for 0.4-3% of all inguinal hernias, but the existence of a massive vesical hernia formation at the inguinoscrotal level is uncommon; a total of 114 cases have been found in the literature. Clinically it should be suspected every time an inguinoscrotal hernia is found in patients over 50 years old with urinary flow obstruction. Diagnosis is usually reached through serial voiding cystouretrography (SVCU). The preferred treatment should be extraperitoneal inguinal herniorrhaphy associated to correction of the obstructive process.     

Measurement of DNA in intervertebral disc and other autofluorescent cartilages using the dye hoechst 33258

BACKGROUND AND OBJECTIVES: Morgagni hernias are unusual congenital diaphragmatic hernias that are generally asymptomatic and discovered incidentally. Surgical treatment is indicated once the diagnosis is made. These hernias have traditionally been repaired by the open abdominal or thoracic approaches. We report a case of Morgagni hernia repaired successfully via the laparoscopic approach. METHODS AND RESULTS: The patient was noted to have a large anteromedial diaphragmatic hernia by chest radiograph and CT imaging. He underwent laparoscopy, during which the hernia was reduced and the defect repaired with mesh placement. We used intracorporeal suture placement to anchor the mesh. The patient recovered uneventfully after a short hospitalization. CONCLUSIONS: The laparoscopic approach for repair of Morgagni hernias offers diagnostic advantages as well as the potential for reduced morbidity when compared to laparotomy. We report intracorporeal knot-tying for fixation of the mesh to be a secure and satisfactory means to achieve the laparoscopic repair.     

Classification systems for groin hernias

All groin hernia classifications are somewhat arbitrary and artificial. Currently, there is no consensus among either general surgeons or hernia specialists as to a preferred system. A survey by Zollinger in 1998 of hernia specialists in North American and Europe showed, that although the Nyhus, Gilbert, and Schumpelick-Arit systems were commonly used, the majority of these specialists still used the traditional classification for groin hernias. It is apparent that only the traditional classification of groin hernias has stood the test of time. As stated by Fitzgibbons, "the primary purpose of a classification system for any disease is to stratify for severity so that reasonable comparisons can be made between various treatment strategies." Given the multiplicity of operative techniques and approaches for the repair of groin hernias, it appears that no one classification system can satisfy all. With time, it is likely that we surgeons will settle upon a given operation for a specific type of inguinal hernia. For that given operation to be accepted as proven best, however, it is essential the competing operations be applied to simliar (classified) groups of groin hernia patients.     

Abdominal incisional hernia occurring after an esophagectomy reconstructed with a gastric tube through an antesternal route: report of a case

A Japanese man, who had undergone a subtotal esophagectomy reconstructed with a gastric tube through an antesternal route for esophageal carcinoma 16 years previously, was admitted to our hospital because of an abdominal incisional hernia. The abdominal incisional hernia was in his upper abdomen and was difficult to push back into the intraabdominal cavity by hand. The hernia was successfully repaired by operation. We thus conclude that an abdominal incisional hernia is a rare but important late-phase complication occurring after an esophagectomy reconstructed with either an antesternal or retrosternal route, and an operation should be the treatment of choice.     

Endoscopically guided percutaneous repair of inguinal hernia through a 2-cm incision. Minihernia repair

BACKGROUND: The laparoscopic repair of inguinal hernia is still controversial. Transabdominal preperitoneal repair violates the peritoneal cavity and may result in visceral injuries or intestinal obstruction. The laparoscopic extraperitoneal approach has the disadvantage of being technically demanding and requires extensive extraperitoneal mobilization. The Lichtenstein repair gives good long-term results, is easy to learn, can be performed under local anesthesia, but requires a larger incision. METHODS: We describe a novel percutaneous tension-free prosthetic mesh repair performed through a 2-cm groin incision. The inguinal canal is traversed with the aid of a 5-mm video-endoscope and the canal is widened using specially designed balloons. Spermatic cord mobilization, identification and excision of the indirect sac, and posterior wall repair are carried out under endoscopic guidance. RESULTS: Between October 1993 and July 1995, 85 primary inguinal hernia repairs (48 indirect and 33 direct) were performed on 81 patients (80 men, one woman) by the author (A.D.). The mean age was 41 years (range 17-83 years). Six repairs were performed under local anesthetic. Mean operative time was 42 min (range 25-74). Mean hospital stay was 1.2 days (0-3 days). The mean return to normal activity was 8 days (2-10 days). Eight complications have occurred: a serous wound discharge, two scrotal hematomas, a scrotal swelling that resolved spontaneously, wound pain lasting 2 weeks, an episode of urinary retention, and two recurrences early in the series (follow-up 1-22 months). CONCLUSION: The endoscopically guided percutaneous hernia repair avoids the disadvantages of laparoscopy (i.e., lack of stereoscopic vision, reduced tactile feedback, unfamiliar anatomical approach, risk of visceral injury), yet the use of endoscopic instrumentation allows operation through a 2-cm incision. The minihernia repair thus combines the virtues of an open tension-free repair with minimal access trauma.     

Inhibition of fos-jun-DNA complex formation by dihydroguaiaretic acid and in vitro cytotoxic effects on cancer cells

The main cause of acquired inguinal hernia is weakness of Fruchaud's deep muscolofascial floor, following metabolically-determined collagen disorders. A technique for the anterior reinforcement of this structure with polypropylene mesh is described here. Following intermuscular decollement, the mesh is placed in direct contact with the surface formed by the transversalis fascia and the transversus abdominis muscle and stretched as extensively as possible. Because the posterior aspect of the inguinal canal is the true barrier to abdominal pressure, the author believe that its direct reinforcement, without interposition of the internal oblique muscle, constitutes the most correct anatomo-surgical approach to hernia repair. This is the case for both indirect hernias, in which the internal ring is reconstructed at a deeper level, and for direct hernias, in which the "tent effect" of the prosthesis is prevented. Ninety-two primary inguinal hernias (56 indirect, 29 direct and 7 direct and indirect) in 87 patients were repaired with this technique. Seventy-nine patients were followed up from 2 to 24 months. Early complications included: 7 ecchymosis, 3 seromas, 2 subcutaneous infections, 3 testicular swellings. Incision and testicular pain for longer than 6 months occurred in 2 cases. No prosthetic infections or recurrences have been detected up to the present.     

Lichtenstein inguinal hernia repair in a primary healthcare setting

BACKGROUND: Given the generally accepted poor outcome of inguinal hernia repair when using nylon darn, and the recent interest in low-tension mesh repair, an attempt was made to demonstrate the feasibility, outcome and patient perception of providing Lichtenstein inguinal hernia repair, using local anaesthesia, wholly within the primary healthcare sector. METHODS: A prospective study reviewed clinical outcome and patient perception in 100 adults referred with inguinal hernia only. No selection was made regarding age, sex, American Society of Anesthesiologists status or previous repairs. Recurrence, pain, infection, return to full function and associated complications were assessed at 24 h, 1 and 6 weeks, and 1 year. Local Community Health Councils assessed patient perception. RESULTS: In the first 100 patients (age range 21-83 (mean(s.d.) 60(14.7)) years; 58 of employable age; 92 men; ten recurrent hernias), no recurrences have occurred at 1 year. Infection rate was 3 per cent. Pain was maximal in the first 24-48 h (median visual analogue scale 5, range 0-10) and reduced rapidly (median 1) at 1 week. Mean time to return to work or full normal activity was 8 days. Some 85 operations were performed within 1 month of diagnosis. In all, 86 patients returned the patient satisfaction questionnaire and 98 per cent of these were 'very pleased' with the service. CONCLUSION: In highly motivated primary healthcare centres, inguinal hernia repair can be undertaken effectively, providing high patient satisfaction, minimal complications and low recurrence rates using the Lichtenstein technique.
