As hérnias inguino-escrotais afetam principalmente equinos machos, sendo caracterizadas como diretas ou indiretas e congênitas ou adquiridas. O emprego da laparoscopia para o fechamento do anel vaginal permite a fixação de implantes e retalhos peritoneais para recobrir a entrada do canal inguinal. As membranas biológicas empregadas como enxerto tecidual apresentam vantagens como baixo custo, fácil armazenamento, pouca reação tecidual, boa incorporação, elasticidade e resistência. Este estudo teve como objetivo avaliar a fixação e a presença do implante de pericárdio homólogo em anel vaginal de equino, realizado por sutura laparoscópica mecânica ou manual por um período de 11 semanas. Neste estudo foram utilizados seis equinos, machos inteiros, da raça Mangalarga, entre três e 12 anos, submetidos à anestesia inalatória, posicionados em Trendelenburg com elevação de 25 º da porção pélvica. Foram criados cinco portais, sendo um na cicatriz umbilical para entrada do laparoscópio e dois portais em cada hemi-abdômem, para acesso dos instrumentais. Em cada animal fixaram-se dois implantes de pericárdio, com medidas de 4 x 5 cm. Em um dos anéis a fixação foi realizada através de sutura manual e no contralateral por sutura mecânica. Avaliou-se o tempo cirúrgico, eventuais complicações, custo, eficiência, processo inflamatório e cicatrização. O tempo necessário para a realização da sutura manual em padrão contínuo simples foi em média 4,7 vezes maior (P > 0,05) que na sutura mecânica, apesar do tempo de sutura manual corresponder a apenas 40% do tempo total do procedimento. Porém, a sutura manual apresentou melhor ancoragem e estabilidade do implante quando comparado com a fixação mecânica. A fixação com endogrampeador aumentou em 50 % o custo total do procedimento quando comparado à sutura manual. Na avaliação macroscópica todos os implantes foram recobertos por tecido cicatricial, apresentando coloração esbranquiçada, difícil delimitação das margens e incorporação do implante pelo peritônio parietal. Os seis implantes fixados com sutura manual permaneceram no local, com boa oclusão do anel vaginal, sendo que em dois foi visualizada, aderência de epíplon e em outro uma sinéquia entre a cicatriz inguinal e o colón maior. Em dois dos seis implantes fixados por sutura mecânica ocorreu deiscência parcial, ocasionando migração de uma das margens e oclusão incompleta do anel vaginal. Uma aderência de epíplon foi observada no implante fixado por grampeamento. O líquido peritoneal no pós-operatório apresentou coloração avermelhada, aspecto turvo e alta celularidade, com diferença significativa (P >0,05), sendo basicamente neutrófilos. Essas alterações diminuíram gradativamente até a quarta semana quando os valores apresentaram-se normais para a espécie. Na avaliação histológica os implantes fixados pelos dois tipos de sutura apresentaram alterações similares, sendo identificado tecido cicatricial em fase de remodelação com moderado infiltrado de células mononucleares, apresentando discreta neovascularização e intensa fibroplasia. O uso de pericárdio homólogo para recobrimento do anel vaginal de equino, fixado através de sutura laparoscópica, manual ou mecânica, proporcionou oclusão satisfatória do anel vaginal, com vantagem para o uso de sutura manual quanto à fixação e custo e para a sutura mecânica quanto ao tempo operatório. / The inguinal hernias affect mainly equine males, being classified as direct or indirect and congenital or acquired. The use of laparoscopy for vaginal ring closure allows the fixation of implants and peritoneal flaps to recover the vaginal canal. The biological membranes employed like flap tissue present advantages such as low cost, easy storage, mild reaction tissue, complete incorporation, elasticity and resistance. The aim of this study was to evaluate the homologous pericardium implanted at equine vaginal ring, carried out by mechanical or manual laparoscopic suture during and after a period of 11 weeks. Six males Mangalarga breed horses between three and 12 years old were used. They underwent general anesthesia, positioned in Trendelenburg with elevation of 25 º of the pelvic region. Five laparoscopic portals were created, one being in the umbilical scar for the entry of the laparoscope and two in each hemi-abdomen for access of the laparoscopic instruments. On each horse two pericardium implants measuring 4 x 5 cm were attached at the vaginal ring regions. In one of the rings the fixation was carried out through manual suture and the contra lateral using mechanical suture. The surgical time, complications, costs, efficiency, inflammatory response and healing were evaluated. The time to carry out the manual suture was 4,7 times longer (P> 0,05) than the mechanical suture. The time for manual suture execution was 40 % of the total time spent for the surgical and anesthetic procedures. However, the manual suture presented better anchorage and stability of the implant when compared with the mechanical fixation. The fixation with intracorporeal staples increased the total cost of the procedure in 50 % when compared to the manual suture. All the implants were covered and incorporated by scar tissue presenting whitish color, without graft definition. Six implants attached by manual suture remained at the place with adequate occlusion of the vaginal ring, and in two of them epiplon adhesions was visualized and in other one a synechia was identified between the inguinal scar and the large colon. In two of six implants attached by mechanical suture, partial dehiscence was occurred, as a result of implant migration and incomplete occlusion of the vaginal ring. An epiplon adhesion was observed in the implant attached by intracorporeal staple. The peritoneal fluid presented changes in color (reddish), aspect (turbidity) and cellularity with significant difference (P> 0, 05), being basically neutrophils. These changes reduced gradually up to the normal values at the fourth week. In the histological evaluation of the implants attached using both types of sutures the aspects were similar presenting healing in remodeling phase with moderate mononuclear cells infiltration, mild neovascularization and intense fibroplasia. The use of homologous pericardium for equine vaginal ring covering, attached by laparoscopic suture, manual or mechanical, provided satisfactory occlusion of the vaginal ring with advantage for the manual suture relative to efficiency and cost and for the mechanical suture relative to reduced surgical time.

Inguinal hernia repair (IHR) is a common ambulatory surgery procedure performed in Canada, after which many patients experience moderate to severe pain. Limited research has been found that examines interventions to reduce pain following ambulatory surgery, and none specifically for patients undergoing IHR. This trial evaluated the effectiveness of an individualized Hernia Repair Education Intervention (HREI) for patients following this ambulatory surgery. Participants (N= 82) were randomized to either the intervention or usual care group pre-operatively in the pre-admission clinic. The HREI included a booklet about managing pain and face-to-face session to discuss its content, and two telephone support calls (before surgery and 24 hours after surgery). The primary outcome was WORST 24 hour pain intensity on movement on post-operative day 2. Secondary outcomes included pain intensity at rest and movement, pain–related interference with activities, pain quality, analgesics taken, and adverse effects at post-operative days 2 and 7. At day 2, the intervention group reported significantly lower scores for all pain intensity outcomes, including WORST 24hr pain on movement (t (df) = 4.7 (73), p< 0.001), WORST 24 hr pain at rest (t (df) = 3.8 (73), p < 0.001), pain NOW at rest (t (df) = 3.3 (73), p = 0.001) and on movement (t (df) = 3.4 (73), p = 0.001). Also on day 2, pain-related interference scores for the intervention group were lower than the usual care group but not significantly different with the bonferroini correction (t (df) = 2.1 (73), p=0.04). The intervention group took significantly fewer opioids on day 2 (t (df) = 3.0 (73), p=0.004). Although there were no differences in any of the pain or interference outcomes on day 7, 36% (n=26) of the total sample reported moderate-severe pain at day 7. Constipation was the adverse effect identified most often, by both groups, on both days 2 and 7.This intervention was effective at post-operative day 2 but revisions need to be made to the intervention to assess for outcomes over a longer period of time.

Ectopic adrenal cortical tissue is not an infrequent incidental finding during abdominal and inguinal operations in infants; however, it is a rare finding in adults with only a few case reports described in the literature. We report a case of adrenal heterotopia as an incidental finding in a hernia sac from a 56 year-old man. We review the literature and discuss the importance of recognizing this rare finding.

Approximately one in four men will have surgery for ingunial hernia in their lifetime. In Sweden, 16 000 procedures are performed each year. To investigate the possible link between handling of nerves and sensory disturbance, 97 groins in 92 patients were examined one year after inguinal hernia surgery. Sensory disturbances were found to be common after open surgery (29 %), but were not seen after the laparoscopic procedures. No significant relationship between sensory disturbance and handling of nerves or pain was seen. The risk for recurrence has been significantly reduced due to the use of prosthetic meshes, but continued surveillance of this important outcome will always be necessary. In that context, the time frame in which recurrence develops in relation to possible risk factors can help our understanding of the underlying mechanisms. To explore such temporal relationships, 142,578 patients were included in a register study. A relative over-risk for early recurrence was seen after suture repair, laparoscopic repair, after postoperative complications, and after surgery for previous recurrence. Corticosteroids are known to decrease pain and nausea after several surgical procedures. In a randomised trial on open hernia surgery, 398 patients were randomised to treatment with 12 mg of betamethasone or placebo. Decreased levels of pain were seen on the day of surgery, the next day and after one month. No difference was seen on days 2-7 and after one year. Nausea was not common and did not differ between the groups. Reoperation is sometimes performed to correct a presumed structural defect thought to cause the long-term pain. In order to evaluate the result of such treatment, 111 cases were analysed based on register data, questionnaires and medical records. Sixty-two per-cent of the patients reported an improvement compared to before the reoperation, but a high level of pain remaining (42 %), and impaired quality of life was seen. There was no clear advantage for any surgical intervention over the other.

Inguinal hernia repair is the most common operation in general surgery. Its main challenge is to achieve low recurrence rates. With the introduction of mesh implants, first in open and later in laparoscopic repair, recurrence rates have decreased substantially. Therefore, the focus has been shifted from clinical outcome, such as recurrence, towards patient-experienced endpoints, such as chronic pain. In order to compare the results of open and laparoscopic hernia repair, a randomised multicentre trial - the Swedish Multicentre trial of Inguinal hernia repair by Laparoscopy (SMIL) - was designed by a study group from 11 hospitals. Between November 1996 and August 2000, 1512 men aged 30-70 years with a primary inguinal hernia were randomised to either laparoscopic (TEP, Totally ExtraPeritoneal) or open (Lichtenstein) repair. The primary endpoint was recurrence at five years. Secondary endpoints were short-term results, frequency of chronic pain and a cost analysis including complications and recurrences up to five years after surgery. In total, 1370 patients, 665 in the TEP and 705 in the Lichtenstein group, underwent operation. With 94% of operated patients available for follow-up after 5.1 years, the recurrence rate was 3.5% in the TEP and 1.2% in the Lichtenstein group. Postoperative pain was lower in the TEP group up to 12 weeks after operation, resulting in five days less sick leave and 11 days shorter time to full recovery. Patients in the TEP group had a slightly increased risk of major complications. Chronic pain was reported by 9-11% of patients in the TEP and 19-25% in the Lichtenstein group at the different follow-up points. Hospital costs for TEP were higher than for Lichtenstein, while community costs were lower due to shorter sick leave. By avoiding disposable laparoscopic equipment, the cost for TEP would be almost equal compared with Lichtenstein. In conclusion, both TEP and Lichtenstein repair have advantages and disadvantages for the patient. Depending on local resources and expertise both methods can be used and recommended for primary inguinal hernia repair.
