RESUMO
Background and Aim: Inguinal hernia is the most common defect of the abdominal wall in 75% and their treatment consists of surgical repair. The technique of choice is laparoscopic because of its overall benefits. However, when this is not available, open approaches may be a viable option. Currently, the most commonly used open techniques are Lichtenstein and Nyhus. However, there are few medium- or long-term studies that have compared outcomes between these two techniques. Methods: This is a retrospective comparative study that included patients undergoing open inguinal hernia correction with mesh, using Lichtenstein open hernioplasty versus Nyhus preperitoneal hernioplasty, in two tertiary referral centers in Bogota, Colombia, during a period of 2 years. A bivariate analysis was performed to compare groups, according to the complications presented between the two techniques. Results: A total of 193 patients were included, of whom 53.36% were men and 112 (58.03%) were approached with the Nyhus technique versus 81 patients with the Lichtenstein technique. Nonabsorbable suture fixation was performed in 100% of patients. Among the main complications, seroma (5.18%), pain (4.14%), bleeding (2.07%), recurrence (10.88%), and reoperation (0.51%) were observed, of which only recurrence showed a statistically significant difference, which is lower in the Nyhus approach (3.57% vs. 20.67%; p < 0.001). No patients died. Conclusions: Both Nyhus and Lichtenstein hernioplasty techniques were shown to cause a low incidence of postoperative complications, with significantly lower recurrence using the Nyhus technique up to 1 year postoperatively.
RESUMO
BACKGROUND: Bariatric surgery is an effective way to lose weight and the laparoscopic gastric sleeve is one of the techniques currently used. Portosplenomesenteric venous thrombosis is a complication that occurs in patients undergoing this surgical technique. At the moment there are no protocols to reduce the risk of this thrombotic event, so we show our experience and propose an algorithm. CASE REPORT: A total of 620 patients were evaluated, six of whom presented between postoperative days 10 to 20 abdominal pain, nausea and dehydration. Therefore, a double contrast abdominal computed tomography scan was carried out, which demonstrated portomesenteric and portoesplenomesenteric thrombosis, in addition to two patients with signs of intestinal ischemia, which required reoperation. One of the patients died of pulmonary thromboembolism.
ANTECEDENTES: La cirugía bariátrica es una forma eficaz de perder peso, y la manga gástrica laparoscópica es una de las técnicas usadas actualmente. La trombosis venosa portoesplenomesénterica es una complicación que se presenta en los pacientes sometidos a esta técnica quirúrgica. En el momento no existen protocolos para disminuir el riesgo de este evento trombótico, por lo cual mostramos nuestra experiencia y proponemos un algoritmo. CASOS CLÍNICOS: Se evaluaron 620 pacientes, de los cuales seis, entre los días 10 y 20 de posoperatorio, presentaron dolor abdominal, náuseas y deshidratación. Se les realizó tomografía computarizada de abdomen con doble contraste, que demostró trombosis portomesentérica y portoesplenomesentérica; además, dos pacientes tuvieron signos de isquemia intestinal y requirieron reintervención quirúrgica. Uno de los pacientes falleció por tromboembolia pulmonar.
