Técnica TAPP en manos jóvenes. Es posible reproducir los resultados de la técnica Lichtenstein para la hernia inguinal sintomática primaria unilateral / Tapp technique performed by young hands. Reproducing the results of the lichtenstein procedure for symptomatic primary unilateral inguinal hernia

RESUMEN Antecedentes: La hernioplastia inguinal es el procedimiento quirúrgico más frecuentemente realizado dentro de la Cirugía General. Se realizan anualmente 20 millones de hernioplastias; la técnica de Lichtenstein y la transabdominal preperitoneal (TAPP) mediante cirugía laparoscópica son las más utilzadas. Objetivo: El objetivo del presente estudio es valorar la factibilidad de la realización del TAPP, en un centro universitario, por parte de residentes y cirujanos jóvenes en formación. Se comparó dicho procedimiento con la técnica de Lichtenstein valorando los resultados en los primeros 30 días del posoperatorio. Las principales variables para estudiar fueron: complicaciones, dolor posoperatorio, estadía hospitalaria y costo del procedimiento. Como variables para estudiar, a largo plazo, se compararon la recidiva herniaria y el dolor crónico. Material y métodos: Se realizó un estudio observacional comparando dos técnicas quirúrgicas utilizando la base de datos del Servicio con información adquirida de forma prospectiva. Se analizaron 80 pacientes, divididos en dos grupos: hernioplastia de Lichtenstein (grupo1) y hernioplastia por TAPP (grupo 2), durante el período comprendido desde mayo de 2015 hasta mayo de 2019, en dos Centros Universitarios de Montevideo Uruguay (Hospital de Clínicas y Hospital Español). Resultados: No hubo diferencia significativa en la estadía hospitalaria y complicaciones posoperatorias. El grupo del Lichtenstein presentó una recidiva herniaria. La hernioplastia laparoscópica presentó un tiempo operatorio promedio de 20 minutos más y el costo de materiales fue mayor. Si bien el dolor posoperatorio en las primeras 24 horas fue mayor en TAPP, el dolor a las 48 horas, 7días, un mes, tres meses y seis meses fue similar en ambos grupos. Conclusión: La técnica de TAPP, para la hernia inguinal primaria unilateral, es factible de ser realizada por cirujanos jóvenes o en formación, con un porcentaje de complicaciones, dolor posoperatorio y recidivas similares al Lichtenstein, aunque con un costo de materiales y tiempo operatorio levemente mayor.

ABSTRACT Background: Inguinal hernia repair is one of the most common procedures in general surgery. Each year, 20 million surgeries for inguinal hernia repaired are performed; the most common techniques used are the Lichtenstein procedure and the transabdominal preperitoneal (TAPP) laparoscopic approach. Objective: The aim of the present study is to evaluate the outcomes of the TAPP approach performed by residents and young surgeons in training in a university center. TAPP was compared with the Lichtenstein and the outcomes at 30 days were compared. The variables considered were complications, postoperative pain, length of hospital stay and procedure-related costs. The long-term variables analyzed were recurrence and chronic pain. Material and methods: We conducted an observational study comparing two surgical techniques, using prospectively acquired information from the database of our department. The cohort was made up of 80 patients undergoing inguinal hernia repair in two university-based hospitals in Montevideo, Uruguay (Hospital de Clínicas and Hospital Español), between May 2015 and May 2019. The patients were divided into two groups: Lichtenstein procedure (group 1) and TAPP procedure (group 2). Results: There were no significant differences in length of hospital stay and postoperative complications. One patient in the Lichtenstein group presented hernia recurrence. Mean operative time was 20 minutes longer with laparoscopic hernia repair, and the cost of the materials was higher. Postoperative pain at 24 hours was greater in the TAPP group, but was similar at 48 hours, 7 days, one month, three months and six months in both groups. Conclusion: The use of TAPP technique for unilateral primary inguinal hernia is feasible to perform by young surgeons or surgeons in training, and the percentage of complications, postoperative pain and recurrences is similar to that of the Lichtenstein technique, although the cost of materials and operative time are slightly higher.

Effect of addition of buprenorphine or dexamethasone to levobupivacaine on postoperative analgesia in ultrasound guided transversus abdominis plane block in patients undergoing unilateral inguinal hernia repair: a prospective randomized double blind controlled trial / 대한마취과학회지

BACKGROUND: The transversus abdominis plane (TAP) block is an effective technique to block the thoracolumbar nerves innervating the anterolateral abdominal wall. This study was conducted to evaluate the analgesic efficacy and opioid consumption with the use of perineural buprenorphine or dexamethasone in TAP blocks after unilateral inguinal hernioplasties. METHODS: This prospective, randomized, double-blinded, placebo-controlled study enrolled 93 patients scheduled for unilateral inguinal hernioplasty, followed by an ultrasound-guided TAP block. The participants were randomized into 3 groups (31 patients each). Group L received 20 ml 0.25% levobupivacaine + 1 ml normal saline (NS); group LB, 20 ml 0.25% levobupivacaine + 0.3 mg (1 ml) buprenorphine; and group LD, 20 ml 0.25% levobupivacaine + 4 mg (1 ml) dexamethasone. The patients were observed postoperatively for 24 h for first rescue analgesic requirement, total rescue analgesic consumption, and pain scores on the numeric rating scale (NRS). RESULTS: The time to first rescue analgesic requirement was significantly longer in Group LB than in groups LD and L (688.87 ± 36.11 min, 601.45 ± 39.85 min, and 383.06 ± 36.21 min, respectively; P < 0.001). The mean total tramadol consumption in the first 24 h was the lowest in group LB (P < 0.001, L vs. LB / LD). Groups LB and LD displayed significantly lower NRS scores than group L (P < 0.001 both). CONCLUSIONS: Levobupivacaine with perineural buprenorphine in a TAP block after unilateral open inguinal hernioplasty facilitates prolonged analgesia and reduced requirement for rescue analgesics compared to perineural dexamethasone, without significant side effects.

Role of antibiotic prophylaxis in open inguinal hernioplasty – A prospective randomized clinical trial.

Background: Inguinal hernia surgery is the most commonly performed surgery worldwide. Lichtenstein tension free repair using polypropylene mesh is the gold standard procedure for inguinal hernioplasty. Wound infection is the most common complication encountered in an surgical procedure. Antibiotic prophylaxis for open inguinal hernioplasty in minimizing wound infection has been a subject of debate since the beginning of mesh repair. We have conducted a randomized clinical trial in our hospital to analyze the usefulne hernioplasty. Material and methods: 60 patients were included in this prospective randomized control trial. 30 of them received 1 g of Injection Cefataxim half an hour before surgery and remaining 30 received injection Multivitamin infusion. Lichtenstein tension free hernia repair using polypropylene mesh was done. Superficial SSI was diagnosed according to CDC criteria. Results: Totally 5 patients developed SSI (8.33%). Out of the five, (6.67%) were in antibiotic group and remaining 3 (10%) were in placebo group (p = 0.64). Odd’s ratio was 0.6429 (CI=0.0995 to 4.1531). All 5 had only superficial SSI; there was no deep surgical site infection (SSI). 2 patients were managed with dressing alone and remaining 3 with antibotics. After 2 weeks, 2 had wound gapping and at four weeks wound was normal in all patients. 2 out of 5 were above 60 years of age and no SSI occurred >30 years of age (p value = 0.59). Conclusion: Routine use of antibiotics is not necessary in all open inguinal hernioplasty. Antibiotics can be reserved only for patients who are in high risk of SSI. Regularizing the use of antibiotics will have a good cost benefit and decrease the emergence of drug resistant organisms.

Tromboflebitis de Mondor del pene tras hernioplastia inguinal / Mondor's thrombophlebitis of the penis after inguinal hernioplasty

Paciente de 22 años de edad con antecedentes de salud. Hacía un mes se le había practicado una hernioplastia inguinal izquierda, y aproximadamente dos semanas después, comenzó a presentar aumento de volumen y dolor en el dorso del pene, tanto al tacto como con la erección. Al examen físico se constató, que la vena dorsal superficial del pene estaba aumentada de volumen, de color rojizo y dolorosa a la palpación. En el ultrasonido doppler-color peniano, se comprobó el engrosamiento de la pared de dicha vena, trombosis de esta, disminución del flujo sanguíneo, así como dolor al contacto del transductor. Se le indicó reposo sexual, tratamiento con antiinflamatorios no esteroideos y corticoides orales, además de iontoforesis local con pomada de heparina sódica. El paciente evolucionó satisfactoriamente, con la desaparición del dolor y la recanalización de la vena dorsal del pene. La aparición de la tromboflebitis de Mondor del pene, con posterioridad a una hernioplastia inguinal, es excepcional. Su sospecha clínica más la confirmación con el ultrasonido doppler-color, son pilares básicos para el diagnóstico de certeza. El tratamiento conservador ofrece óptimos resultados.

A male patient aged 22 years with a history of health problems. One month before, he had undergone left inguinal hernioplasty, but two weeks after surgery, he began suffering pain in the back of the penis together with increased volume, both on touch and at erect state. The physical examination revealed that the superficial dorsal vein of the penis was more swollen, red-colored and painful on palpation. Doppler-color ultrasound of the penis confirmed thickening of the vein wall, thrombosis, lower blood flow and patient's feeling of pain when the transducer touched it. He was prescribed non-steroidal anti-inflammatory drugs plus oral corticosteroids, cessation of sexual intercourse, in addition to local ionphoresis with sodium heparin ointment. The patient's progression was satisfactory since pain disappeared and the dorsal vein of the penis was re-canalized. Mondor's thrombophlebitis of the penis rarely occurs after inguinal hernioplasty. Clinical suspicion plus Doppler-color US confirmation are basic pillars for a correct diagnosis. The conservative treatment offers optimal outcomes.
