Abdominal wall hernia repair: a long-term comparison of Sepramesh and Dualmesh in a rabbit hernia model.

Surgeons are faced with a wide variety of mesh products, which they can use to perform tension-free abdominal wall hernia repair. The purpose of this study is to compare Sepramesh (SM) and Dualmesh (DM) in terms of strength of tissue incorporation, mesh shrinkage, and adhesiogenesis. We conducted a prospective, randomized trial using 24 New Zealand White rabbits. Each animal underwent creation of a standardized ventral hernia defect and was randomized to receive either SM or DM repair. There were 12 animals in each study arm. Five months postoperatively, the animals were sacrificed and the hernia repairs were analyzed. Specimens were evaluated for strength of incorporation (SOI), mesh shrinkage, as well as the type and amount of adhesions. SOI for DM was not statistically different from SM (37.2N vs 40.8N). DM underwent significantly more shrinkage than did SM (50.8% vs 32.6%, P < 0.0001). Adhesions were predominantly omental in nature. DM demonstrated a greater amount of adhesed area as a percentage of the mesh (30.7% vs 25.2%), but fewer adhesions in terms of absolute area involved (636 mm2 vs 717 mm2). This difference was not statistically significant. Previous studies, terminated at 30 days, demonstrated an increased SOI for SM as compared to DM. This study shows that SOI for DM continues to increase over time such that it is equivalent to DM at 5 months. Though there is increased mesh shrinkage for DM, adhesions to the two materials are equivalent.

[Laparoscopic repair of incisional hernias and bulky umbilical hernias: technique and results].

Historically, incisionnal hernias and bulky umbilical hernias were closed by direct suturing. These techniques generated a significant number of recurrences (31% to 51%). More recently the prosthetic nets, revolutionized hernia surgery. Their use in this type of surgery then made passed below 10% the rate of recurrence. But it persisted a morbidity related to the wound healing higher than 12%. The development of double layer prostheses allowed the treatment by laparoscopy. These one are feasible, show a low rate of recurrence. The prosthesis is placed in the peritoneum. Parietal morbidity, as well as the postoperative pain is clearly decreased. The recurrence rate is probably the same then by laparotomy. For these reasons we have chosen the laparoscopic technique.

Peritoneography, a safe method to assess the bilaterality of inguinal hernias in children with an obvious unilateral hernia or cryptorchidism (100 cases).

A safe method to assess the bilaterality of inguinal hernias by herniography in 100 children up to 13 years was successfully adopted for the young patients with already a clinical unilateral hernia or undescended testis. In 40% of the cases was an occult contralateral open processus vaginalis peritonei radiologically discovered and surgically removed during the anesthesia for primary inguinal pathology. This is a safe preventive and curative technique to treat inguinal hernias in infants and children.

[Laparoscopic hernia repair of recurrent hernias].

Successful treatment of recurrent inguinal hernias is still a problem, in spite of the availability of several different methods. We present our experience with laparoscopic TAP repair, which was performed in 154 patients with 168 recurrent inguinal hernias after traditional anterior repairs. Our results show an acceptable complication rate (5.4%, n = 9) and a low re-recurrence-rate (1.8%, n = 3), combined with the benefit of the minimal access technique, so that this procedure can be recommended in recurrent inguinal hernia repair.

Trocar site hernia after laparoscopic ventral hernia repair.

BACKGROUND: The incidence of trocar site hernia (TSH) after laparoscopic ventral hernia repair (LVHR) is reported to be low. The present study investigates the associated risk factors, with a view to preventing this complication. METHODS: A retrospective study was made of the incidence of TSH in a personal series of LVHR, recording anthropometric and clinical data on the patients. Risk factors were assessed by bivariate and multivariate analyses. The patients were subjected to clinical and telephone follow-up. RESULTS: In a series of 27 LVHR, the incidence of TSH was 22% (6 patients). The use of meshes larger than 10 x 15 cm for LVHR was the only TSH risk factor to reach statistical significance. Female gender and diabetes showed a higher incidence in the TSH group. CONCLUSIONS: The use of large meshes may be a risk factor for TSH. We believe this to be due to dilatation of the trocar orifice during introduction of the mesh, and also to postoperative retraction of the mesh.

Pathophysiology of congenital diaphragmatic hernia. VIII: Inhaled nitric oxide requires exogenous surfactant therapy in the lamb model of congenital diaphragmatic hernia.

The pathophysiology of the lamb model of congenital diaphragmatic hernia (CDH) involves pulmonary hypoplasia, pulmonary hypertension, and surfactant deficiency. Inhaled nitric oxide (NO) is a highly selective pulmonary vasodilator. The aim of this study was to determine the effects of inhaled NO on pulmonary gas exchange, acid-base balance, and pulmonary pressures in a lamb model of CDH with or without exogenous surfactant therapy. At the gestational age of 78 days (full term, 145 days) 11 lamb fetuses had a diaphragmatic hernia created via a left thoracotomy and then were allowed to continue development in utero. After cesarean section, performed at term, six lambs received exogenous surfactant therapy (50 mg/kg, Infasurf) and five served as controls. All animals were pressure-ventilated for 30 minutes and then received 80 ppm of inhaled NO at an F1O2 of .9 for a 10-minute interval. Compared with the control lambs, the lambs with exogenous surfactant therapy had higher pH (7.17 +/- .06 v 6.96 +/- .07; P < .05), lower PCO2 (73 +/- 8 v 122 +/- 20, p < .05), and higher PO2 (153 +/- 38 v 50 +/- 23; P < .05). In control CDH lambs (without surfactant), inhaled NO did not improve pH, PCO2, or PO2, or decrease pulmonary artery pressure. In CDH lambs given exogenous surfactant, NO decreased pulmonary artery pressures (42 +/- 4 v 53 +/- 5; P < .005) and further improved PCO2 and PO2. NO also made the difference between pulmonary and systemic artery pressures more negative in the surfactant-treated lambs (-15 +/- 4 v -2.3 +/- 2.4; P < .005).(ABSTRACT TRUNCATED AT 250 WORDS)

Current surgical management of congenital diaphragmatic hernia: a report from the Congenital Diaphragmatic Hernia Study Group.

BACKGROUND: Repair of congenital diaphragmatic hernia (CDH) has changed from an emergent procedure to a delayed procedure in the last decade. Many other aspects of management have also evolved since the first successful repair. However, most reports are from single institutions. The lack of a large multicenter database has hampered progress in the management of congenital diaphragmatic hernia (CDH) and makes determination of the current standard difficult. METHODS: The CDH study group was formed in 1995 to collect data from multiple institutions in North America, Europe, and Australia. Participating centers completed a registry form on all live-born infants with CDH during 1995 and 1996. Demographic information, data about surgical management, and outcome were collected for all patients. RESULTS: Sixty-two centers participated, with 461 patients entered. Overall survival was 280 of 442 patients (63%) where survival was recorded. The defect was left-sided in 78%, right-sided in 21%, and bilateral in 1%. A subcostal approach was used in 91% of patients, with pleural drainage used in 76%. A patch of some kind was used in just over half (51%) of the patients, with polytetrafluoroethylene being the most commonly used material (81%) in those patients with a patch. The mean surgical time was 102 minutes, with an average blood loss of 14 mL (range, 0 to 500 mL). The overwhelming majority of patients underwent repair between 6:00 AM and 6:00 PM (289 of 329, 88%). Nineteen percent of patients had surgical repair on extracorporeal membrane oxygenation (ECMO) at a mean time of 170 hours into the ECMO course (range, 10 to 593 hours). The mean age at surgery in patients not treated with ECMO was 73 hours (range, 1 to 445 hours). CONCLUSIONS: The multicenter nature of this report makes it a snapshot of current management. The data would indicate that prosthetic patching of the defect has become common, that after-hours repair is infrequent, and that delayed surgical repair has become the preferred approach in many centers. Furthermore, the mean survival rate of 63% indicates that despite decades of individual effort, the CDH problem is far from solved. This highlights the need for a centralized database and cooperative multicenter studies in the future.

Pathophysiology of congenital diaphragmatic hernia. V. Effect of exogenous surfactant therapy on gas exchange and lung mechanics in the lamb congenital diaphragmatic hernia model.

The aim of this study was to assess the impact of surfactant deficiency on the pathophysiology of congenital diaphragmatic hernia (CDH). Pregnant ewes were operated on at 80 days of gestation for creation of a diaphragmatic hernia in the lambs. Twenty-one lambs survived to be delivered by cesarean section and were studied. Compliance was improved when surface tension effects were removed by saline solution in lungs of both control animals and lambs with CDH; however, the lungs of the lambs with CDH still had significantly impaired compliance. In a second series of experiments, two groups were studied: a surfactant-treated and a control, nontreated group. Surfactant was given prophylactically into the liquid-filled lungs before the first breath. All lambs were paralyzed and sedated and their lungs mechanically ventilated with 100% oxygen for 30 minutes; gas exchange was then assessed, pressure-volume data were obtained, and compliance was calculated. Surfactant significantly improved gas exchange; arterial oxygen pressure increased from 39 +/- 11.4 to 316 +/- 53.6 mm Hg, arterial carbon dioxide pressure decreased from 148 to 63 mm Hg, and pH increased from 6.87 to 7.16 (p < 0.001). Lung volume at 25 cm H2O, functional residual capacity, and compliance were all increased (p < 0.02). Thus, in the CDH lamb model, pulmonary mechanics are impaired by both parenchymal and surfactant abnormalities. Both lung mechanics and gas exchange are markedly improved by exogenous surfactant therapy.

Umbilical hernia, inguinal hernias, and hydroceles in children: diagnostic clues for optimal patient management.

The assessment of pediatric patients with a possible umbilical hernia, inguinal hernias, or hydroceles can often be problematic for the pediatric nurse practitioner. Understanding the embryologic processes related to these conditions may increase the diagnostic capabilities of the practitioner. Clues to assist in the differential diagnosis and current treatment modalities will be offered. Tips for parental guidance related to these conditions will enhance the team approach to effective referrals and optimal treatment of the children in this clinical population.

[Posterior gastro-esophago-phreno-plasty (PGEPP) in the treatment of hiatal hernia and of esophagogastric reflux. Experience in over 500 cases. Anterior gastro-esophago-phreno-plasty (AGEPP) in the prevention of sliding hiatal hernia and of esophagogastric reflux. Experience in over 300 cases].

On the basis of the anatomophysiological assumption that the abdominal oesophagus is kept in its seat by the meso-oesophagus and that the complex functional role of the gastro-oesophageal junction is conditioned essentially by the inferior oesophageal sphincter under the influence of intra-abdominal and endogastric pressure variables, posterior gastro-oesophagophreno-plasty (p.g.p.p.) is proposed to offset the destruction or severe insufficiency of the meso-oesophagus and hence for the treatment of hiatal hernia and of regurgitation. This retro-oesophageal tuberous valve involves simultaneous fixation of the stomach and oesophagus to the pillars of the diaphragm, first on the right and then on the left, and the fixation of the fundus to the left diaphragmatic dome. Anterior gastro-oesophago-phreno-plasty is proposed on the basis of the finding that damage of any kind to the meso-oesophagus can cause the oesophagus to rise in the chest and thus disturb inferior sphincter function and possibly lead to the onset of regurgitation and hernia. The pre-oesophageal tuberous valve employed involves simultaneous fixation of stomach and oesophagus to the pillars of the diaphragm, first left and then right, and the fixation of the fundus to the left diaphragmatic dome. Anterior plasty is almost always confined to patients who have undergone vagotomy of the trunk without complex isolation of the oesophagus.

Gastric acid secretion (GAS) and hiatal hernia. II. Relationship between GAS and clinical results after hernia repair.

The indications for surgical procedures reducing gastric acid secretion in patients with hiatal hernia and symptomatic gastroesophageal reflux remain unclear. In a study of the postoperative results in 40 patients operated upon with modified Husfeldt hernia repair only, the results were assessed in relation to BAO and PAO. No correlation was found between the clinical results and BAO or PAO in patients in whom the reflux was successfully corrected by the procedure. It is concluded that gastric acid-reducing procedures are not indicated in patients in whom correction of reflux is anticipated.

[Intercostal abdominal hernias. Apropos of 2 cases with right hernia].

Two patients presented with abdominal wall hernia in the 9th intercostal space on the right. Such localizations are extremely rare, occurring after closed or open chest or abdominal trauma producing two contiguous orifices in the diaphragm and the intercostal chest wall. The diaphragmatic orifice is due to a low lateral disinsertion and the intercostal orifice is situated in the 7th to 11th space, occurring immediately or later. Intercostal abdominal hernias are sometimes discovered due to pain or digestive or respiratory disorders. Clinical diagnosis is simple. CT scan confirms the clinical diagnosis and give a precise description. A direct or abdominal surgical approach is used to close the diaphragmatic orifice and the intercostal space with an unabsorbed suture. Muscle plasty or a unabsorbable prosthesis may be necessary. Early recurrence may occur if the orifice in the diaphragm is ignored.

[Crural hernia after inguinal hernia repair. A technical note].

A case of femoral hernia following repair of an inguinal hernia with the Shouldice method is presented. The authors discuss the pathogenesis, suggest the use of ultrasound for a precise preoperative diagnosis, and propose the "plug" technique of Lichtenstein as the method of choice for the repair. This method offers a minimally invasive approach, without disturbing the previous inguinal repair and it is very simple to perform.

[A proposed classification of inguinocrural hernias. The classification of hernias in the inguinal and crural regions in the adult as a function of their surgical therapy].

Surgery for the treatment of inguinal and femoral hernias has recent years acquired numerous increasingly modern, innovative techniques. This has been possible thanks modern, innovative techniques. This has been possible thanks to the introduction of prosthetic material which is better tolerated by the tissues and to the utilization of new ways of approach. A new method of hernia classification, no longer based on anatomical criteria but on a broader evaluation which takes multiple aspects into account, is now needed to decide on valid criteria for choice of operation, at the same time expressing themselves in a common language which will allow the results to the verified.

Richter hernia in a sacral foramen: new site for richter hernia.

This is a report of the first case to my knowledge, of a Richter hernia occurring in a sacral foramen. A 60-year-old woman had gradual onset of postsacral pain and swelling. The area was drained and small intestinal contents found. Laparotomy showed that a Richter hernia had occurred in the third right sacral foramen. The bowel had incarcerated and perforated into the posterior sacral area, without leakage into the peritoneal cavity.
