A novel method of bilateral patent processus vaginalis ligation in transumbilical single-site multiport laparoscopic orchiopexy.

Objective: To evaluate safety and efficacy of a novel method of bilateral patent processus vaginalis ligation in transumbilical single-site multiport laparoscopic orchiopexy for children. Methods: A retrospective study was carried out comparing the novel ligation and conventional ligation performed by a single surgeon between July, 2017-July, 2018. The patients were divided into the novel group (42 cases) and the conventional group (59 cases). In the novel group, transumbilical single-site multiport laparoscopic orchiopexy was performed and the bilateral internal rings was stitched with "8" pattern suture. In the conventional group, the conventional TriPort laparoscopic orchiopexy was performed and purse string suture was used to fix the internal rings. The parameters of operative duration time, postoperative hospital stay; postoperative complications were compared between 2 groups. Results: All operations were successful. No Perioperative period complications were found and all patients were discharged within 4-6 days after operation. There is no statistic difference in the surgery time and hospitalization day. However, there is significant difference in the Pain face scale scores after day 2(1.60±0.73 VS 2.02±0.86). And there is no scar and the satisfactory cosmetic could be seen in scrotum and inguinal area in the novel group. Conclusion: The novel ligation was safety and efficacy. It is relatively easy to perform with smaller scar and less pain. We propose the novel ligation as a more viable treatment option for pediatric cryptorchidism with bilateral patent processus vaginalis.

Decreasing operating room costs via reduction of surgical instruments.

BACKGROUND: Rising costs in health care demand waste reduction and improved efficiency throughout the hospital. Surgeons have an important role in regard to the number of instruments used in procedures. Previous studies have demonstrated instrument maintenance and sterilization cost approximately $0.51-$0.77 per instrument and found that only 13-21.9% of instruments opened are used. OBJECTIVE: The aim of the study was to reduce the surgical trays so that more than 50% of the instruments are used leading to a cost savings of at least 20% per tray. This was begun with the minor urology tray which is primarily used for orchiopexy and hernia repair. STUDY DESIGN: This was a single-site, prospective study. A Plan, Do, Study, Act cycle was used. A multidisciplinary team including urologists, surgical technicians, and a central processing department representative was developed. Inguinal orchiopexy with hernia, scrotal orchiopexy, and inguinal hernia cases were randomly chosen to count the total instruments used in each procedure. The exact instruments were recorded every third case to obtain a sample of variable patients and surgeon preferences. The percentage of utilization was calculated, and a list of instruments used was created. Those not used or used less than 20% of the time were removed. The new list was reviewed with the option to add or eliminate instruments. The approved reduced list was then implemented as the genitourinary (GU) minor tray. Finally, the instruments used in 10 inguinal orchiopexy with hernia cases, 10 scrotal orchiopexy cases, and 10 inguinal hernia cases were counted. The percentage of utilization was calculated. This process was then replicated in other surgical trays. RESULTS: The GU minor instrument tray was reduced from 57 to 35 instruments, a 39% reduction in size. Scrotal orchiopexy uses the least instruments (16.9), a utilization percentage of 48.3% after reduction. Inguinal orchiopexy with hernia repair uses the most number of instruments (25.1) with 71.7% utilization after reduction, compared with 43% before reduction. Using the cost analysis performed by Stockert and Langerman, $11.22 was saved during each procedure; this translates to a cost savings of $3489.42 annually. After reduction, only 10% of the cases required an extra instrument to be opened. Three other surgical trays were reduced using the same method, yielding a potential savings of $14,588. DISCUSSION: Baseline data demonstrates low average instrument utilization rangin from 21.1% to 49.1% per case. It is estimated that each instrument costs from $0.51 to $3.19. Decreasing the number of instruments opened with each surgical procedure is a viable way to decrease costs and efficiency in the operating room. CONCLUSIONS: Initially, the GU minor tray was successfully reduced by 39%, followed by the other surgical trays. A multidisciplinary approach is critical for success. This study showed an excellent opportunity for cost savings by decreasing reusable waste in the operating room.

Single port laparoscopic orchidopexy in children using surgical glove port and conventional rigid instruments.

PURPOSE: We review the literature and describe our technique for laparoendoscopic single-site orchidopexy using a glove port and rigid instruments. We assessed the feasibility and outcomes of this procedure. MATERIALS AND METHODS: We retrospectively reviewed the case records of all children who had undergone laparoendoscopic single-site orchidopexy by use of a surgical glove port and conventional rigid instruments for a nonpalpable intraabdominal testis between January 2013 and September 2014. RESULTS: Data from a total of 20 patients were collected. The patients' mean age was 18 months. All cases had a nonpalpable unilateral undescended testis. Fourteen patients (70%) had an undescended testis on the right side and six patients (30%) had an undescended testis on the left side. Seventeen patients underwent primary orchidopexy. Three patients underwent single-port laparoscopic Fowler-Stephens orchidopexy for the first and the second stage. Average operating time was 57 minutes (range, 40 to 80 minutes). No patient was lost to follow-up. At follow-up, 2 testes were found to have retracted out of the scrotum and these were successfully dealt with in a second operation. One testis was hypoplastic in the scrotal pouch. There were no signs of umbilical hernia. CONCLUSIONS: Single-port laparoscopic orchidopexy using a glove port and rigid instruments is technically feasible and safe for various nonpalpable intraabdominal testes. However, surgical experience and long-term follow-up are needed to confirm the superiority of this technique.

Effects of ketamine and midazolam on emergence agitation after sevoflurane anaesthesia in children receiving caudal block: a randomized trial / Efeitos de cetamina e midazolam sobre a incidência de agitação pós-anestesia com sevoflurano em crianças submetidas ao bloqueio caudal: estudo randomizado / Efectos de la ketamina y el midazolam sobre la incidencia de agitación postanestesia con sevoflurano en niños sometidos al bloqueo caudal: estudio aleatorizado

Background and objectives: Emergence agitation is a common postanaesthetic problem in children after sevoflurane anaesthesia. We aimed to compare the effects of ketamine and midazolam administered intravenously, before the end of surgery, for prevention of emergence agitation in children who received caudal block for pain relief under sevoflurane anaesthesia. Methods: 62 American Society of Anesthesiologists patient classification status I children, aged 2–7 years, scheduled for inguinal hernia repair, circumcision or orchidopexy were enrolled to the study. Anaesthesia was induced with sevoflurane 8% in a mixture of 50% oxygen and nitrous oxide. After achieving adequate depth of anaesthesia, a laryngeal mask was placed and then caudal block was performed with 0.75 mL kg−1, 0.25% bupivacaine. At the end of the surgery, ketamine 0.25 mg kg−1, midazolam 0.03 mg kg−1 and saline were given to ketamine, midazolam and control groups, respectively. Agitation was assessed using Paediatric Anaesthesia Emergence Delirium scale and postoperative pain was evaluated with modified Children's Hospital of Eastern Ontario Pain Scale. Results and conclusions: Modified Children's Hospital of Eastern Ontario Pain Scale scores were found higher in control group than in ketamine and midazolam groups. Paediatric Anaesthesia Emergence Delirium scores were similar between groups. Modified Children's Hospital of Eastern Ontario Pain Scale and Paediatric Anaesthesia Emergence Delirium scores showed a significant decrease by time in all groups during follow-up in postanaesthesia care unit. The present study resulted in satisfactory Paediatric Anaesthesia Emergence Delirium scores which are below 10 in all groups. As a conclusion, neither ketamine nor midazolam added to caudal block under sevoflurane anaesthesia did show further effect on emergence agitation. In addition, pain relief still seems to be the major factor in preventing emergence ...

Justificativa e objetivos: A incidência de agitação é um problema pós-anestésico comum em crianças após a anestesia com sevoflurano. Nosso objetivo foi comparar os efeitos de cetamina e midazolam administrados por via intravenosa, antes do término da cirurgia, para prevenir a incidência de agitação em crianças submetidas ao bloqueio caudal para alívio da dor sob anestesia com sevoflurano. Métodos: Foram inscritos no estudo 62 pacientes pediátricos, entre 2-7 anos, estado físico classificado de acordo com a Sociedade Americana de Anestesiologistas (ASA: I), programados para correção de hérnia inguinal, circuncisão ou orquidopexia. A anestesia foi induzida com sevoflurano a 8% em uma mistura de oxigênio (50%) e óxido nitroso (50%). Depois de atingir a profundidade adequada da anestesia, uma máscara laríngea foi colocada e, em seguida, o bloqueio caudal foi feito com bupivacaína a 0,25% (0,75 mL kg−1). No fim da cirurgia, cetamina (0,25 mg kg−1), midazolam (0,03 mg kg−1) e solução salina foram administrados aos grupos cetamina, midazolam e controle, respectivamente. A incidência de agitaçio foi avaliada com a escala Paediatric Anaesthesia Emergence Delirium (PAED) e a dor no período pós-operatório avaliada com a escala modificada Children's Hospital of Eastern Ontario Pain Scale (mCHEOPS). Resultados e conclusões: Os escores de dor da escala modificada mCHEOPS foram maiores no grupo controle do que nos grupos cetamina e midazolam. Os escores PAED foram semelhantes entre os grupos. Os escores dessas duas escalas mostraram uma diminuição significativa do tempo em todos os grupos durante o acompanhamento em sala de recuperação pós-anestesia. O presente estudo resultou em escores satisfatórios da escala PAED, que ficaram abaixo ...

The unidirectional testicular tunneller: a simple, safe and novel device for orchidopexy in patients with palpable undescended testes.

PURPOSE: Inguinal orchidopexy is already considered a safe procedure, this paper describes a simple new surgical instrument designed to make the operation easier, simpler and quicker, whilst reducing tissue trauma, in particular to the deep ring. The result of its use in two centres is presented. METHODS: A unidirectional testicular tunneller has been developed comprising a head, shaft and eye. At operation, following testicular mobilisation, the tunneller is passed through the groin incision into the scrotum and a dartos pouch created by cutting against the head of the instrument. This allows more of a "no-touch" technique with less back and forth movement through the inguinal canal. The testis is attached to the eye of the instrument and pulled into the scrotum before fixation. RESULTS: From November 2000 to December 2011, two surgeons operated on 592 boys using the instrument. 93 procedures were bilateral. All operations proceeded without incident and a healthy testis was safely and permanently placed in the scrotum. There were no complications related to the use of the tunneller. All were treated as day cases. CONCLUSION: The instrument described in this paper simplifies inguinal orchidopexy, improves procedural safety and is felt to reduce surgical trauma. In view of these advantages and the absence of complications related to this instrument, its use in inguinal orchidopexy is recommended.

[Robotic surgery in paediatric urology: current status and perspectives]. / Robotische Chirurgie in der Kinderurologie: Aktueller Stand und Perspektiven.

The increasing experience obtained through laparoscopy has resulted in the evolution of ablative and reconstructive procedures in the field of paediatric urology. Apart from the established methods of laparoscopic nephrectomy and orchidopexy, nowadays laparoscopic hemi-nephrectomy and pyeloplasty have become standard therapeutic surgical alternatives. Nevertheless, many of these procedures require a high level of experience in laparoscopic preparation and stitching techniques and are thus performed in institutions with greater laparoscopic experience. With the introduction and evolution of the robotic-assisted technique and the availability of smaller instruments and ports (8 and 5 mm), there has been an evolution in the spectrum of complex ablative and reconstructive procedures in the field of paediatric urology as well. Nevertheless, there is a lack of randomised trails and the literature available in this area consists manly of case reports. The purpose of this article is to present the current status and perspectives of robotic-assisted surgery in the field of paediatric urology.

[Analysis of laparoscopic orchidopexy in intra-abdominal testis]. / Ergebnisse der laparoskopischen Orchidopexie beim nicht palpablen Hoden.

Laparoscopy is an established diagnostic procedure but is less frequently used as a therapeutic method for impalpable testes. To compare the results of the classic two-stage orchidopexy described by Fowler-Stephens with a testicular vessel-sparing single-stage approach in the management of intra-abdominal testes we retrospectively analyzed our data.From January 2005 to September 2010, 105 patients (mean age 32 months) underwent laparoscopy for impalpable testes. In cases of intra-abdominal testes, laparoscopic orchidopexy was performed either in a two-stage procedure including initial ligation of the testicular vessels or as a direct single-stage procedure without ligation of the vessels. The results of both approaches were evaluated postoperatively clinically and by ultrasonography. Among the 122 impalpable testes 63 were located intra-abdominally; single-stage orchidopexy was performed in 29 testes whereas a two-stage approach was conducted in 14 testes. Fourteen gonads had to be removed due to atrophy and in six cases no testis was found at all. In the other 59 cases inguinal exploration followed resulting in 22 orchidopexies, 34 removals and 3 blind-ending vessels. During a mean follow-up of 17 months none of the 29 testes treated by single-stage orchidopexy atrophied or reascended. By contrast, two cases of atrophy, one reascent and one subumbilical wound infection occurred after the two-stage procedure. Considering our excellent experiences with single-stage management, we conclude that the single-stage approach is a reliable, safe and efficacious treatment modality of intra-abdominal testes. However, the two-stage procedure including testicular vessel ligation should be restricted to high abdominal testes with very short vessels.

Initial experience in children using conventional laparoscopic instruments in single-incision laparoscopic surgery.

BACKGROUND: Single-incision laparoscopic surgery (SILS) has been successfully performed in children using 5-mm reticulating instruments. There are, however, few reports investigating the use of conventional instruments in SILS in the pediatric population. METHODS: We conducted a retrospective review of all consecutive children who underwent SILS from October 2009 to January 2010, with the procedure being solely performed by conventional 3- and 5-mm instruments through a standard access technique. RESULTS: A total of 19 SILS procedures were successfully performed in children aged 3 to 15 years. They included appendectomy (n = 10), nephrectomy (n = 1), combined cholecystectomy and splenectomy (n = 2), cholecystectomy (n = 1), high ligation for varicocele (n = 2), excision of Meckel diverticulum (n = 1), and staged orchidopexy and exploration for impalpable testis (n = 2). There was one conversion to conventional laparoscopic surgery, and that occurred in our first case of splenectomy. All the patients had smooth recovery from surgery without complications. CONCLUSIONS: Using conventional instruments in SILS is technically feasible in children from simple to complex procedures and may have the potential to popularize this approach by eliminating the mandatory demand for specially designed instruments.
