Ligasure versus diathermy hemorrhoidectomy under spinal anesthesia or pudendal block with ropivacaine: a randomized prospective clinical study with 1-year follow-up.

PURPOSE: We evaluate the safety and efficacy of a spinal anesthesia with lidocaine versus a local anesthesia of pudendal block with ropivacaine combined with intravenous sedation in the hemorrhoidectomy procedure and also we compared the short- and long-term efficacy of conventional diathermy versus Ligasure diathermy hemorrhoidectomy. METHODS: Seventy-four patients of grade III or IV hemorrhoids were randomized to conventional diathermy hemorrhoidectomy under spinal (n = 19) or local anesthesia (n = 18) and Ligasure diathermy hemorrhoidectomy under spinal (n = 17) or local anesthesia (n = 20). Time of follow-up was 12 months. RESULTS: Patients operated under local anesthesia had less pain (p < 0.01), less analgesic requirements (p < 0.001), shorter hospital stay (p < 0.01), and less postoperative complications (p < 0.05). A shorter operating time (p < 0.001) and less complications at 4 months postoperatively (p < 0.05) was observed in the Ligasure group, but differences at 12 months were not found. CONCLUSIONS: Hemorrhoidectomy under local anesthesia with pudendal block with ropivacaine and sedation reduced postoperative pain, analgesic requirements, and postoperative complications, and can be performed as day-case procedure. Ligasure diathermy hemorrhoidectomy reduced operating time and was equally effective than conventional diathermy in long-term symptom control.

Gestión clínica de la lista de espera en un servicio de cirugía general / Management of the hospital waiting list in a general surgery department

Introducción. Presentamos nuestra experiencia en la gestión clínica de la lista de espera del Servicio de Cirugía General del Hospital de Viladecans (hospital público del Institut Català de la Salut).Objetivos. Diseño de una base de datos para la gestión clínica de la lista de espera del servicio de cirugía general, y evaluación de los resultados tras su diseño y aplicación.Material y método. Base de datos creada a tal fin, y que recoge todos los pacientes incluidos en lista de espera para intervención quirúrgica electiva durante un período de 5 años (desde el 1 de enero de 1996 al 31 de diciembre de 2000).Resultados. El número de intervenciones quirúrgicas electivas año tras año se ha mantenido por debajo de la demanda, creando un déficit que equivaldría a incrementar nuestra actividad en un 23,8 por ciento para adecuarla a la demanda. La lista de espera para la cirugía electiva ha estado condicionada a la presión de urgencias, que ha ido progresivamente en aumento. El criterio establecido de prioridad se ha demostrado útil, habiendo operado el 60,8 por ciento de los pacientes preferentes antes de 3 meses, y el 65,2 por ciento de los pacientes no preferentes entre 3 y 9 meses.Conclusiones. 1) Existe un progresivo incremento de la demanda de servicios quirúrgicos en nuestra área de influencia. 2) Se ha logrado una mejor gestión clínica, con un progresivo descenso en el número de anulaciones y un incremento en la actividad quirúrgica. 3) Se ha reducido el número de reprogramaciones de un 32 a un 14,3 por ciento. 4). Calculamos un déficit de recursos (horas de quirófano) que equivaldría a un 23,8 por ciento de nuestra actividad quirúrgica actual para poder adecuarnos a la demanda. 5) La base de datos diseñada por nosotros ha demostrado ser un instrumento útil de gestión de nuestra lista de espera (AU)

[Central venous catheter location by endocavitary ECG: an alternative to chest radiography]. / Comprobación de catéter central por electrocardiografía endocavitaria: la alternativa a la radiografía de tórax.

BACKGROUND: The location of a central venous catheter is checked with a chest radiograph. Right endocavitary electrocardiography (ECG), a technique in which the catheter is connected to the ECG recorder wire to record ECG in DII, might be an alternate method to check the position of the catheter. When the catheter enters the right atrium, there is a large increase in the amplitude of P wave. The aim of this study was to compare the efficacy of endocavitary ECG against the chest radiography as a method to check the position of a central catheter, and to determine whether the ECG method can replace the radiological method. MATERIAL AND METHODS: One-hundred central catheters which location was checked by ECG and by chest X-ray entered the study. Efficacy of endocavitary ECG, delay between catheter insertion and radiological check, and the cost of the two methods were studied. RESULTS: Endocavitary ECG determined that de catheter was in a correct position in 80 cases and malpositioned in 20 cases. ECG check agreed with radiological check in 93 catheters. There were 4 false-positive and 3 false-negative cases. The efficacy of endocavitary ECG was 93% (sensitivity: 82%; specificity: 81%; positive predictive rate: 95%; negative predictive rate: 85%). Catheter location was checked immediately on insertion by ECG in all cases, while radiological check was delayed 32 +/- 25 min in the emergency department and 68 +/- 206 min in the admitted patients. The cost of the ECG method was less than that of the radiological method. CONCLUSIONS: The check of the position of a central venous catheter by endocavitary ECG is taster, cheaper, and of similar efficacy to the radiological method. Endocavitary ECG can replace chest X-rays to check the position of the catheter in more than 90% of cases.

[Efficacy of the ilioinguinal and iliohypogastric block in the treatment of the postoperative pain of inguinal herniorrhaphy]. / Eficacia del bloqueo ilioinguinal e iliohipogástrico en el tratamiento del dolor postoperatorio de la herniorrafia inguinal.

INTRODUCTION: The ileoinguinal-ileohypogastric block (IHB) improves pain control in inguinal hernioplasty. OBJECTIVE: To determine the efficacy of the IHB on the treatment of postoperative pain in inguinal herniorrhaphy, and to compare the effect of its use before and after incision for diminishing pain and postponing the first dose of analgesia. PATIENTS AND METHODS: Sixty-eight patients scheduled for inguinal herniorrhaphy with mesh were enrolled and distributed randomly in 4 groups as follows: 1) IHB before incision using 0.25 ml/kg bupivacaine 0.5% with no vasoconstrictor; 2) IHB after incision with the same dose of bupivacaine; 3) IHB before incision with 0.25 ml/kg of serum; and 4) IHB after incision with 0.25 ml/kg of serum. Pain was evaluated on visual analog scales employing facial expressions and verbal description, a patient questionnaire and time elapsing between surgery and the first dose of analgesia. The evaluations were performed in the postoperative recovery unit and on the ward 8 and 24 hours after surgery. RESULTS: The total overall score for postoperative pain was lower in the bupivacaine group than in the placebo group (9.2 +/- 4.4 and 1.5 +/- 3.9, respectively; p = 0.026). The first dose of analgesia was given to those who received placebo between the second and third hour after surgery, whereas it was given between the fourth and fifth hour to the bupivacaine group. No significant differences were found between infiltration before and after incision. CONCLUSIONS: IHB decreases pain, delaying the need for a first dose of analgesic and improving patient comfort. Its use is therefore recommended for relief of postoperative pain.
