Comparison of postoperative chronic inguinal pain between the lichtenstein and laparoscopic techniques in the treatment of inguinal hernia: a systematic review and meta-analysis.

PURPOSE: Currently, inguinal hernias are highly prevalent in the Brazilian population, accounting for 75% of all abdominal wall hernias. The recommended treatment to correct them is inguinal herniorrhaphy, which can be performed through open surgery, mainly using the Lichtenstein technique, or laparoscopically, primarily through Transabdominal Preperitoneal Repair (TAPP) or Total Extraperitoneal Repair (TEP) approaches. Like any surgery, these procedures have post-operative complications, with pain being the most common and debilitating. Currently, in European and Brazilian guidelines, the open Lichtenstein and endoscopic inguinal hernia techniques are recommended as best evidence-based options for repair of a primary unilateral hernia providing the surgeon is sufficiently experienced in the specific procedure. In that matter, the surgeon should make a choice based on assessment of the benefits and risks of performing each of them, and practice shared making decision with it patient. Therefore, the objective of this review was to assess the incidence of chronic postoperative pain by comparing the aforementioned surgical approaches to evaluate which procedure causes less disability to the patient. METHODS: The search conducted until May 2024 was performed on Medline (PubMed), Cochrane (CENTRAL), and Lilacs databases. The selection was limited to randomized clinical trials, nonrandomized clinical trials and cohort studies comparing TAPP or TEP to LC, evaluating the incidence of chronic postoperative pain published between 2017 and 2023. Evidence certainty was assessed using the GRADE Pro tool, and bias risk was evaluated with the RoB 2.0 tool and ROBINS I tool. Thirteen studies were included.  RESULTS: The meta-analysis showed a significant difference between the groups in both techniques, favoring the laparoscopic approach, which had a lower occurrence of postoperative inguinodynia with a relative risk of 0.49 (95% CI = 0.32, 0.75; I2 = 66% (P = 0.001); Z = 3.28 (P = 0.001) with low certainty of evidence. CONCLUSION: The presence of chronic postoperative pain was lower in laparoscopic TEP/TAPP techniques when compared to the open Lichtenstein technique, meaning that the former can bring more benefits to patients who requires inguinal herniorrhaphy. Nevertheless, further randomized clinical trials are needed to optimize the analysis, minimizing the bias.

Groin Hernia in Females Routinely Treated by Totally Extraperitoneal Laparoscopic Approach.

BACKGROUND AND OBJECTIVES: There is a dearth of studies on laparoscopic treatment of female groin hernia. Our study assessed the outcome of groin hernia repair in females employing the totally extraperitoneal laparoscopic (TEP) access. METHODS: Data of all females who were subjected to laparoscopic groin herniorrhaphy, from August 1998 to February 2020 were retrospectively obtained. Groin hernia repair was routinely started with TEP access. RESULTS: A total of 2,399 patients who underwent laparoscopic groin herniorrhaphy, 254 (10.6%), were females. Most females (n = 191; 75.2%) had single hernia and the remaining (n = 63; 24.8%) had bilateral hernias, making a total of 317 hernias operated. Indirect inguinal hernia was the most common hernia type (72.5%), followed by femoral hernia (17.4%) and direct hernia (10.1%). Prior lower abdominal operations were recorded in 97 (38.2%) patients. Conversion to a laparoscopic transabdominal preperitoneal procedure was performed due to technical difficulties to dissect the preperitoneal space in 17 patients (6.7%) and to open procedure in only one patient (0.4%) with incarcerated femoral hernia in whom an incidental perforation of the small bowel occurred. Intra- and postoperative complications occurred in 12 (4.7%) and 15 (5.9%) patients, respectively. There was no mortality. Most patients (n = 221; 87%) were discharged on the same day of the operation. Hernia recurrence was diagnosed in 6 patients (2.4%). CONCLUSION: It is concluded that females with groin hernia may be successfully treated with totally extraperitoneal laparoscopic access, with low conversion and complication rates.

Rectal damage control: when to do and not to do / Control de daños de recto: que hacer y que no hacer

Abstract Rectal trauma is uncommon, but it is usually associated with injuries in adjacent pelvic or abdominal organs. Recent studies have changed the paradigm behind military rectal trauma management, showing better morbidity and mortality. However, damage control techniques in rectal trauma remain controversial. This article aims to present an algorithm for the treatment of rectal trauma in a patient with hemodynamic instability, according to damage control surgery principles. We propose to manage intraperitoneal rectal injuries in the same way as colon injuries. The treatment of extraperitoneal rectum injuries will depend on the percentage of the circumference involved. For injuries involving more than 25% of the circumference, a colostomy is indicated. While injuries involving less than 25% of the circumference can be managed through a conservative approach or primary repair. In rectal trauma, knowing when to do or not to do it makes the difference.

Resumen El trauma de recto es poco frecuente, pero generalmente se asocia a lesiones de órganos adyacentes en la región pélvica y abdominal. Estudios recientes han cambiado los paradigmas del manejo tradicional derivados del trauma militar, mostrando mejores resultados en la morbilidad y mortalidad. Sin embargo, las técnicas de control de daños en el trauma rectal aún son controvertidas. El objetivo de este articulo es proponer el algoritmo de manejo del paciente con trauma rectal e inestabilidad hemodinámica, según los principios de la cirugía de control de daños. Se propone que las lesiones del recto en su porción intraperitoneal sean manejadas de la misma manera que las lesiones del colon. Mientras que el manejo de las lesiones extraperitoneales del recto dependerá del compromiso de la circunferencia rectal. Si es mayor del 25% se recomienda realizar una colostomía. Si es menor, se propone optar por el manejo conservador o el reparo primario. Saber que hacer o que no hacer en el trauma de recto marca la diferencia.

Robotic assisted eTEP ventral hernia repair: Brazilian early experience.

PURPOSE: The enhanced view totally extraperitoneal (eTEP) concept first applied to inguinal hernias has become an important tool in the armamentarium of ventral hernia repair. The purpose of this report is to date the first brazilian robotic-assisted eTEP ventral hernia repair case series. METHODS: A review of a prospectively maintained database was conducted in patients who underwent robotic-assisted enhanced view totally extraperitoneal (eTEP) for ventral hernia repair between June 2018 and January 2020. Patients demographics, preoperative hernia characteristics, intraoperative variables and postoperative outcomes were evaluated. RESULTS: Our review identified 74 patients submitted to the procedure. Thirty-one patients (41.8%) presented primary ventral hernias (PVHs) and 43 patients (58.2%) presented incisional hernias (IHs). Female patients were predominant in both groups PVHs and IHs with 17 (22.9%) and 22 (29.7%) respectively, with a total of 39 patients (52.7%). Mean BMI was 29.1 kg/m2 (range 21.3-48.0 kg/m2) with higher mean BMI rates of 30.3 kg/m2 in the IHs group (range 22-48 years). A lateral dock setup was utilized in 55 cases (74.4%), having the inferior and superior dock setup in 18 (24.3%) and 1 (1.3%) cases respectively. Mean console time was 148.3 (range 75-277 min) and 192.6 min (range 66-301 min) in the PVHs and IHs groups respectively. There were no intraoperative complications or conversions. Average length of stay was 1.5 days. Four patients were readmitted within 30 days of surgery. There were no reoperation or cases of intraparietal herniation in this cohort. No hernia recurrence was verified during the mean 230.7 days of follow up in both groups. CONCLUSION: We present the first brazilian series to-date of the robotic assisted eTEP approach for ventral hernia repairs. Although long term outcomes require further analysis, its feasibility and reproducibility in experienced surgeons hands are evident, with safe and acceptable early postoperative outcomes.

Femoral hernia: uncommon, but associated with potentially severe complications / Hérnia femoral: incomum, mas associada a complicações potencialmente graves

ABSTRACT Background: Although the laparoscopic access is becoming the preferable treatment for femoral hernia, there are only few studies on this important subject. Aim: To assess the outcomes of the totally extraperitoneal laparoscopic (TEP) access in the treatment of femoral hernia. Methods: Data of 62 patients with femoral hernia who underwent herniorrhaphy were retrospectively reviewed. The diagnosis of femoral hernia was established by clinical and/or imaging exams in 55 patients and by laparoscopic findings in seven. Results: There were 55 (88.7%) females and 7 (11.3%) males, with female to male ratio of 8:1. The mean age was of 58.9±15.9 years, ranging from 22 to 92 years. Most patients (n=53; 85.5%) had single hernia and the remaining (n=9; 14.5%) bilateral, making a total of 71 hernias operated. Prior lower abdominal operations were recorded in 21 (33.9%) patients. Conversion to laparoscopic transabdominal preperitoneal procedure was performed in four (6.5%). Open herniorrhaphy was needed in two (3.2%), one with spontaneous enterocutaneous fistula in the groin region (Richter's hernia) and the another with incidental perforation of the adjacent small bowel that occurred during dissection of hernia sac. There was no mortality. Conclusion: Femoral hernia is uncommon, and it may be associated with potentially severe complications. Most femoral hernias may be successfully treated with totally extraperitoneal laparoscopic access, with low conversion and complication rates.

RESUMO Racional: Embora o acesso laparoscópico esteja se tornando o tratamento preferencial para a hérnia femoral, poucos são os estudos sobre esse importante assunto. Objetivo: Avaliar os resultados do acesso laparoscópico totalmente extraperitoneal no tratamento da hérnia femoral. Métodos: Os dados de 62 pacientes com hérnia femoral que foram submetidos a herniorrafia foram revisados ​​retrospectivamente. O diagnóstico foi estabelecido por exames clínicos e/ou de imagem em 55 pacientes e por achados laparoscópicos em sete. Resultados: Havia 55 (88,7%) mulheres e 7 (11,3%) homens, com proporção feminino/masculino de 8: 1. A média de idade foi de 58,9±15,9 anos (22-92). A maioria (n=53, 85,5%) apresentava hérnia única e o restante (n=9, 14,5%) bilaterais, perfazendo um total de 71 hérnias femorais operadas. Operações prévias no abdome inferior foram registradas em 21 (33,9%) pacientes. A conversão para procedimento pré-peritoneal transabdominal laparoscópico foi realizada em quatro (6,5%). Herniorrafia aberta foi necessária em dois pacientes (3,2%), um com fístula enterocutânea espontânea na região da virilha (hérnia de Richter) e o outro com perfuração incidental do intestino delgado adjacente que ocorreu durante a dissecção do saco herniário. Não houve mortalidade. Conclusão: A hérnia femoral é incomum e pode estar associada a complicações potencialmente graves. A maioria das hérnias femorais pode ser tratada com sucesso através do acesso laparoscópico totalmente extraperitoneal, com baixas taxas de conversão e complicações.

Behavior of free omental grafts without vascular anastomosis implanted in cats experimental wounds / Comportamento do enxerto omental livre sem anastomose vascular implantado em feridas experimentais de gatos

It is known that skin healing in cats is slower and has a higher complication rate than in dogs, what leads to search for new resources to enhance this process. Omentum properties in the aid of tissue repair are known and, among the forms of extraperitoneal omentalization, the use of free omental grafts without vascular anastomosis is advantageous, but little studied; there is no knowledge about its effect on skin healing, nor if its still viable when implanted in the subcutaneous space. Thus, the present study aimed to describe possible alterations produced by free omental graft without anastomosis inserted in the subcutaneous space, by means of macroscopic clinical analysis of the implantation region in cats. Twenty intact female cats were divided into two groups (Group 1: treated animals; Group 2: controls) of similar size. All animals were subjected to ovariosalpingohysterectomy (OSH) prior to the induction of an experimental wound for the implantation of the omental graft. Wounds were evaluated on days 1, 2, 4, 8, and 15 postsurgery and then weekly until no lesions were noted. Data regarding color, consistency, presence or absence of crusts, wound resistance, and volume measurements were recorded. There was activation of the omentum on the 4th day of evaluation with reduction of hemorrhage and an increase in the resistance to traction of the experimental wound. We concluded that the omentum without vascular anastomosis is capable of maintaining its viability and exert positive influence on the repair process without showing deleterious signs on the implantation site.(AU)

Sabe-se que a cicatrização de pele em gatos é mais lenta e apresenta índice maior de complicações que nos cães, dai a importância da busca de novos recursos para estimular o processo cicatricial. São conhecidas as propriedades do omento no auxílio ao reparo tecidual e, dentre as formas de omentalização extraperitoneal, o uso do omento livre sem anastomose vascular é vantajoso, porém pouco estudado; não há conhecimento sobre seu efeito na cicatrização cutânea, tampouco se permanece viável quando implantado no espaço subcutâneo. Sendo assim, o presente trabalho tem como objetivo avaliar possíveis alterações produzidas pelo enxerto omental livre sem anastomose inserido no espaço subcutâneo, por meio da avaliação clínica macroscópica da região de implantação em gatos. Foram utilizadas 20 gatas, de idade entre um e sete anos, sem alterações em exame de sangue, FIV/FELV negativas. Os animais foram divididos em dois grupos (Tratado e Controle) de igual tamanho, diferindo quanto à utilização do enxerto de omento livre. Foi realizada cirurgia de ovariossalpingohisterectomia (OSH) em todos os animais, previamente à criação da ferida experimental para implantação ou não do enxerto omental. As feridas foram avaliadas nos dias 1, 2, 4, 8 e 15 do pós-operatório e a partir de então semanalmente, até nenhuma alteração ser observada. Foram anotados dados referentes à coloração, consistência, presença de crosta, resistência da ferida e medidas do volume. Nos resultados destacou-se a ativação do omento no quarto dia de avaliação, observada pelo aumento de volume, com redução de hemorragia e aumento na resistência da ferida experimental à tração. Conclui-se que o omento em sua forma livre sem anastomose é capaz de manter sua viabilidade e exercer influência positiva sobre o processo de reparo, sem demonstrar sinais deletérios sobre a região implantada.(AU)

Albumin for cirrhotic patients with extraperitoneal infections: A meta-analysis.

BACKGROUND AND AIM: Bacterial infections are among the main causes of death in patients with cirrhosis. While there are unquestionable benefits of using albumin in patients with spontaneous bacterial peritonitis, the benefits of albumin are controversial for those with extraperitoneal infections. The aim was to compare the use of albumin associated to antibiotics and antibiotics alone in cirrhotic patients with extraperitoneal infections. METHODS: A systematic review was performed using MEDLINE and Embase databases. Randomized controlled trials comparing albumin associated to antibiotics and antibiotics alone in cirrhotic patients with extraperitoneal infections were considered eligible, as long as at least one of the following outcomes was evaluated: mortality and renal dysfunction. Meta-analysis was performed using the random effects model, through the Mantel-Haenszel method. The study protocol was registered at PROSPERO platform (CRD42018107191). RESULTS: The literature search yielded 812 references. Three randomized controlled trials fulfilled the selection criteria and were included in this meta-analysis. There was no evidence of significant difference between the groups regarding mortality in 30 days (risk ratio [RR] = 1.62, 95% confidence interval [CI]: 0.92-2.84, P = 0.09, I2 = 0%) or in 90 days (RR = 1.27, 95% CI: 0.89-1.83, P = 0.19, I2 = 0%). Regarding renal dysfunction, there was also no evidence of significant difference between the groups (RR = 0.55, 95% CI: 0.25-1.19, P = 0.13, I2 = 0%). CONCLUSION: There is no evidence of significant benefits of using albumin for cirrhotic patients with extraperitoneal infections regarding mortality or renal dysfunction.

Abstract A description is presented on the surgical experience of 10 patients who underwent laparoscopic extraperitoneal para-aortic lymphadenectomy (LEPL) in order to classify locally advanced cervical carcinoma (LACC), as well as a literature review. Methods: A literature search was performed in MEDLINE and EMBASE using the following keywords:''Uterine Cervical Cancer; Cancer Staging; Lymph Nodes; Lymph Node Excision; Laparoscopy; extraperitoneal''. The surgical technique for LEPL is described, as well as the outcomes of the 10 patients who underwent surgery. Results: A total of 10 patients, with ages between 29 and 65 years and with LACC underwent LPEL. There were surgical blood losses between 5 to 30 cc, a lymph node count between 2 and 11, no surgical complications, and a hospital stay of between 1 and 3 days. Conclusion: This is the first experience reported for LPEL for LACC in Colombia. It is a safe, feasible, and useful procedure to identify para-aortic involvement.

Mesh Displacement After Bilateral Inguinal Hernia Repair With No Fixation.

BACKGROUND AND OBJECTIVES: About 20% of patients with inguinal hernia present bilateral hernias in the diagnosis. In these cases, laparoscopic procedure is considered gold standard approach. Mesh fixation is considered important step toward avoiding recurrence. However, because of cost and risk of pain, real need for mesh fixation has been debated. For bilateral inguinal hernias, there are few specific data about non fixation and mesh displacement. We assessed mesh movement in patients who had undergone laparoscopic bilateral inguinal hernia repair without mesh fixation and compared the results with those obtained in patients with unilateral hernia. METHODS: From January 2012 through May 2014, 20 consecutive patients with bilateral inguinal hernia underwent TEP repair with no mesh fixation. Results were compared with 50 consecutive patients with unilateral inguinal hernia surgically repaired with similar technique. Mesh was marked with 3 clips. Mesh movements were measured by comparing initial radiography performed at the end of surgery, with a second radiographic scan performed 30 days later. RESULTS: Mean movements of all 3 clips in bilateral nonfixation (NF) group were 0.15-0.4 cm compared with 0.1-0.3 cm in unilateral NF group. Overall displacement of bilateral and unilateral NF groups did not show significant difference. Mean overall displacement was 1.9 cm versus 1.8 cm in the bilateral and unilateral NF groups, respectively (P = .78). CONCLUSIONS: TEP with no mesh fixation is safe in bilateral inguinal repairs. Early mesh displacement is minimal. This technique can be safely used in most patients with inguinal hernia.

[Complicated diverticular disease debuting as necrotising fasciitis of pelvic limb. A case report]. / Enfermedad diverticular complicada iniciada como fascitis necrosante de miembro pélvico. Reporte de caso.

BACKGROUND: Diverticular disease, and the diverticulitis, the main complication of it, are widely studied diseases with multiple chronic cases reported in the literature, but there are no atypical presentations with extra-abdominal symptoms coupled with seemingly unrelated entities, such as necrotising fasciitis. CLINICAL CASE: Female 52 years old, was admitted to the emergency department with back pain of 22 days duration. History of importance: Chronic use of benzodiazepines intramuscularly. Physical examination revealed the presence of a gluteal abscess in right pelvic limb with discoloration, as well as peri-lesional cellulitis and crepitus that stretches across the back of the limb. Fasciotomy was performed with debridement of necrotic tissue. Progression was torpid with crackling in abdomen. Computed tomography showed free air in the cavity, and on being surgically explored was found to be complicated diverticular disease. DISCUSSION: It is unusual for complicated diverticular disease to present with symptoms extra-peritoneal (< 2%) and even more so that a diverticulitis is due to necrotising fasciitis (< 1%). The absence of peritoneal manifestations delayed the timely diagnosis, which was evident with the crackling of the abdomen and abdominal computed tomography scan showing the parietal gaseous process. CONCLUSION: All necrotising fasciitis needs an abdominal computed tomography scan to look for abdominal diseases (in this case diverticulitis), as their overlapping presentation delays the diagnosis and consequently the treatment, making a fatal outcome inevitable.

Linfadenectomía retroperitoneal lumboaórtica laparoscópica por vía extraperitoneal en cáncer testicular no seminoma / Extraperitoneal laparoscopic retroperitoneal lymph node dissection in non-seminomatous testicular cancer

Objective: The aim is to describe the technique of extraperitoneal laparoscopic access for retroperitoneal lymph node dissection in a series of patients with testis cancer stage A. Material and Methods: The extraperitoneal approach was performed in 5 patients with stage A testicular cancer. The technique includes the creation of a totally extraperitoneal space, full exposition of the retroperitoneum and classic retroperito-neal lymph node dissection. We analyzed demographic data, histology, access and surgical complications, estimated blood loss and follow up. Results: The average age was 29.4 years old (22-41). The mean operative time was 144 minutes, with an estimated blood loss of 42.4 ml. There were no surgical complications. The average hospital stay was 33.6 hr, and mean number of lymph nodes was 27.4 (24 -32). In long-term follow up there was no recurrence. Discussion: The extraperitoneal approach is an alternative access for retroperitoneal lymph node dissection in testis cancer patients. It allows avoiding potential intestinal lesions and there is no contraindication in patients with prior abdominal surgery.

Objetivo: Mostrar la experiencia en la técnica de disección lumboaórtica por vía totalmente extra-peritoneal, en un grupo de pacientes con cáncer testicular en estadio A. Material y Métodos: La serie está formada por 5 pacientes, portadores de un tumor testicular no seminoma, en estadio A. En ellos se planteó como alternativa la linfadenectomía retroperitoneal lumboaórtica laparoscópica. La técnica quirúrgica consistió en la formación de un espacio extraperitoneal, con rechazo de peritoneo, exposición del retroperitoneo y disección linfática clásica. Se analizaron los datos demográficos, histología, complicaciones del acceso y la técnica quirúrgica, tiempo operatorio, sangrado estimado y seguimiento a largo plazo. Resultados: El tiempo operatorio medio fue de 144 min, con un sangrado medio estimado en 42,5 ml (20-150 ml). No hubo complicaciones intra ni postoperatorias. El tiempo medio de hospitalización fue de 33,6 h. El número medio de nodos linfáticos resecados fue de 27,4 (24 a 32). Con un promedio de seguimiento de 134 meses, no ha habido recurrencia retroperitoneal ni diseminación a distancia. Discusión: La vía extraperitoneal es una alternativa de acceso para la disección linfática retroperitoneal en pacientes con cáncer testicular. Permite evitar potenciales lesiones intestinales y es factible de realizar en pacientes con cirugía abdominal previa.

¿Existen ventajas en el abordaje extraperitoneal para el tratamiento del aneurisma de aorta abdominal? / Are there advantages in the extraperitoneal approach for the treatment of abdominal aortic aneurysm?

Existen controversias acerca de las posibles ventajas del abordaje transperitoneal vs. extraperitoneal en la cirugía de aneurisma de aorta abdominal; con este último, algunos estudios reportan menor morbilidad y complicaciones operatorias. Este estudio describe los resultados que se obtuvieron con los dos abordajes en un solo centro de referencia. Es un estudio retrospectivo, descriptivo, de doce años, en un grupo de 299 pacientes con diagnóstico de aneurisma de aorta abdominal que fueron intervenidos de manera electiva y distribuidos en dos grupos según el abordaje (transperitoneal = grupo 1, extraperitoneal = grupo 2). En total se operaron 93 pacientes en el grupo 1 y 206 pacientes en el 2. En ambos predominaron pacientes del sexo masculino. La edad media fue de 68 años. Las frecuencias de co-morbilidades fueron similares en los dos grupos. Se registró una tendencia a menor número de reoperaciones en el grupo 2 (12,9% vs. 5,8%), De otra parte, se observó una tendencia de mayores complicaciones post-operatorias en el grupo 1 con una frecuencia de 30,1% vs. 12,6% en el grupo 2; sin embargo, el tipo de complicaciones fue similar. Los resultados mostraron una estancia hospitalaria media de 13,3 días (DE ± 10,4) vs. 7,19 días (DE ± 4,20) p= 0,00001, estancia post-operatoria media de 9,16 días (DE ± 8,1) vs. 5,62 días (DE ± 3,46) p= 0,001 y estancia en la unidad de cuidados intensivos media de 2,76 días (DE ± 4,19) vs. 1,56 días (DE ± 1,86) p= 0,00001 en los grupos 1 y 2 respectivamente. La mortalidad inmediata total fue de 3,3%. La frecuencia de mortalidad para los grupos fue de 6,5% (n= 6) vs. 1,9% (n= 4) respectivamente. En nuestra experiencia el abordaje por la vía extraperitoneal presenta una tendencia favorable para los pacientes en cuanto a la estancia hospitalaria, la estancia en la unidad de cuidados intensivos, la frecuencia de complicaciones post-operatorias y la frecuencia de re-intervenciones en el post-operatorio inmediato. Debido al tamaño de la muestra no puede concluirse que hubo una diferencia estadísticamente significativa en cuanto a la mortalidad; sin embargo se observó una tendencia a la reducción de la misma con el abordaje extraperitoneal.

There are current controversies over the benefits of the extraperitoneal vs the transperitoneal approach for repairing an infrarenal abdominal aortic aneurysm. Several studies report a reduction in morbidity and mortality with the former approach. This study reports the short term results using both approaches at one reference center. This is a 12 year, retrospective descriptive study of 299 patients who underwent an elective open repair of an abdominal aortic aneurysm, distributed in two groups: transperitoneal approach group=1, extraperitoneal approach group=2. A total of 93 patients in group 1 and 206 in group 2 were intervened, mainly male patients with an median age of 68 years. The frequencies of co-morbidities were similar in both groups. There was a reduced tendency of reoperations in group 2 (12.9%vs 5.8%), and a greater tendency of postoperative complications in group 1 (30.1% vs 12.6%). However, the types complications were similar. The results show a median hospital stay of 13.3 days (SD+- 10,4) vs. 7.19 days (SD+- 4.20) p=0.00001, median post-operative stay of 9.16 days (SD-+ 8,1) vs. 5.62 days (SD+- 3,46) p= 0.001 and median intensive unit stay of 2.76 days (SD+-4.19) vs 1.56 days (SD+-1.86) p=0.00001 in group 1 y 2 respectively. Early global mortality was 3.3% with a distribution frequency of 6.5% (n=6) in group 1 and 1.9% (n=4) in group 2. In our experience, the extraperitoneal approach offers better results regarding hospital, postoperative and intensive care unit stay, as well as post-operative re-operation rates and complications. Because of the small sample size, the mortality difference was not statistically significant; however, we found an important tendency towards improved mortality rates with this approach.

Abordaje extraperitoneal de la columna lumbar: experiencia en 192 casos / Extraperitoneal approach of lumbar spine: a 192 cases experience

Exponer nuestra experiencia en el abordaje extraperitoneal de la columna lumbar y comparar con la literatura relacionada. Estudio realizado en el Hospital de Clínicas Caracas y en el Centro Médico Docente La Trinidad. Estudio retrospectivo, basado en la revisión de historias clínicas de 131 pacientes sometidos a 192 abordajes de columna lumbar en el perìodo comprendido entre mayo de 2004 y noviembre 2009. 47,5% de los pacientes son masculinos y 52,5% femeninos. La edad promedio fue de 42,78%. El tiempo quirúrgico promedio fue de 138,56 minutos. La tasa global de complicaciones postoperatorias fue de 18,32%. La estancia hospitalaria promedio fue de 2,33 días. Para el reemplazo de discos intervertebrales se han utilizado múltiples abordajes, siendo el extraperitoneal el más recomendado, ya que permite una amplia exposición de la anatomía, disminuye la incidencia de daño nervioso, evita el trauma muscular paraespinal y disminuye la estancia hospitalaria.

Inform our experience with extraperitoneal approach of lumbar disc compare with literature. Study performed at Hospital de Clinicas Caracas and Centro Médico Docente La Trinidad. Retrospective study based on history review ofr 131 patients with 192 lumbar approaches between May 2004 and November 2009. 47,5% males, 52,5 females, mean age was 42,78%. Mean surgical time was 138,56 minutes. Postoperative complications rate was 18,32%. Mean hospital stay was 2,33 days. Extraperitoneal approach for disc replacement is the recommended operation. It permits better anatomy identification, less trauma to muscles and nerves, and less hospital stay.

Morbimortalidad del traumatismo de recto extraperitoneal / Morbimortalidade do traumatismo do reto extraperitoneal / Morbidity and mortality of extraperitoneal rectal trauma

INTRODUCCION: Los traumatismos del recto extraperitoneal representan el 3 por ciento al 5 por ciento de todos los traumatismos y heridas abdominales y se destacan por la elevada morbimortalidad que presentan si no son diagnosticados y tratados precoz y adecuadamente. En la actualidad existe falta de consenso con respecto al óptimo manejo quirúrgico en el medio civil. OBJETIVO: Relatar la experiencia en el tratamiento evaluando aquellos factores que influyeron en la morbimortalidad. METODOS: Estudo retrospectivo descriptivo onde se revisaron los prontuarios de todos los pacientes operados por traumatismo recto extraperitoneal, entre enero de 1998 y diciembre de 2007. Las variables índice de trauma abdominal, intervalo entre trauma y cirugía y tipo de cirugía inicial fueron relacionadas con las complicaciones infecciosas y mortalidad. RESULTADOS: Se evaluaron 13 pacientes, 5 por herida de arma de fuego, 5 por autoempalamiento y 3 por trauma cerrado. El índice de trauma abdominal promedio en infectados y fallecidos fue superior a 25. El 61 por ciento de los pacientes(8) fueron operados antes de las 8 horas. La tasa de infección fue del 61,5 por ciento y el 90 por ciento de los pacientes infectados requirieron nuevas cirugías. La mortalidad de la serie fue de 38,5 por ciento (5 pacientes). En los pacientes intervenidos después de las 8 horas se registró un 80 por ciento de infección perirrectal y un 80 por ciento de mortalidad independientemente del tipo de cirugía realizada. CONCLUSIONES: El retraso en el tratamiento mayor 8hs y el índice de trauma abdominal mayor 25 fueron los principales factores asociados a infección perirrectal y mortalidad en esta serie. La ausencia de drenaje presacro y de lavado rectal distal se asoció a mayor incidencia de infección perirrectal.

BACKGROUND: Extraperitoneal rectal injuries represent 3 to 5 percent of all traumatisms and abdominal injuries, and they are highlighted by their high morbidity/mortality presented if not early and appropriately diagnosed and treated. Nowadays there is not a consensus related to an optimal surgical management. AIM: To relate the experience in treating this disease, evaluating factors that influence mortality and morbidity. METHODS: It consisted in a descriptive retrospective study where it was reviewed handbooks of all extraperitoneal rectal trauma patients operated between January 1998 and December 2007. The abdominal trauma rate, the interval between trauma and surgery and the initial surgery's type were related to infectious complications and mortality. RESULTS: There were evaluated 13 patients: 5 injured by firearms, 5 autoimpalament and 3 by closed trauma. The abdominal trauma mean rate of infected and dead was more than 25. 61 percent of patients (n=8) underwent surgery before 8 hours. The infection rate was 61.5 percent and 90 percent of infected patients required additional surgeries. The series' mortality was 38.5 percent (5 patients). In patients operated after 8 hours there was perirectal infection in 80 percent of them, and 80 percent of mortality regardless of surgery performed type. CONCLUSIONS: The delay over 8 hours in treating and the abdominal trauma rate over 25 were the main factors associated with perirectal infection and mortality in this series. Absence of presacral drainage and distal rectal wash were correlated with increased incidence of perirectal infection.
