A Comparative Analysis of Single Umbilical Tangential Incision vs. Conventional Three-port Totally Extraperitoneal Inguinal Hernia Repair

PURPOSE: We have explored the question of what benefits SUTI-TEP can provide over conventional three-port TEP (C-TEP) surgery for the treatment of inguinal hernia. METHODS: One hundred forty cases (70 SUTI-TEP and 70 C-TEP) were reviewed in this study. SUTI-TEP procedure was carried out with SILS™ port as we reported before. Patient demographics and perioperative outcomes of SUTI-TEP were analyzed and compared with those of C-TEP. RESULTS: There was no conversion to open surgery or C-TEP in SUTI-TEP group. Median VAS immediate postoperatively was slightly higher in SUTI-TEP group, but it was statistically significant. POD 7th day pain after surgery were similar in both groups. Regarding the length of operation time, SUTI-TEP group (71.2 min) was significantly longer than that of the C-TEP group (41 min) (p<0.001). There was no major morbidity or mortality postoperatively in either group. There was also no recurrence or chronic pain during follow up. Patient overall satisfaction including cosmetic outcome was excellent in SUTI-TEP group. CONCLUSION: Although the longer operation time tends to be required, SUTI-TEP can provide better cosmesis and patient satisfaction, and also safety. That may be good indicator of the success of after surgery. Also we should not presume that one large incision causes less pain than small multiple incision because it is just single one. If there is more pain in one single wound, we should find the solution through the innovation of technology or preventive measures.

Outcomes of Total Laparoscopic Hysterectomy Using a 5-mm Versus 10-mm Laparoscope: A Randomized Control Trial.

STUDY OBJECTIVE: To determine if the use of a 5-mm umbilical incision and laparoscope would result in a higher likelihood of earlier discharge from hospital after total laparoscopic hysterectomy (TLH) compared with a 10-mm umbilical incision and laparoscope. Secondary objectives of the study were to determine if the use of a 5-mm laparoscope would lead to a reduction in postoperative pain scores and a shorter operating time without an increase in complication rates. DESIGN: Prospective, randomized, double-blinded, clinical trial (Canadian Task Force classification I). SETTING: A tertiary care setting. PATIENTS: Seventy-eight patients scheduled for TLH were prospectively recruited. INTERVENTIONS: Women undergoing TLH were assigned to either a 5-mm umbilical port and laparoscope (5LH) or a 10-mm umbilical port and laparoscope (10LH). All patients underwent a standardized operative technique and anesthetic protocol. Patients and research assistants responsible for postoperative pain assessment were blinded to group. Analysis was by intention-to-treat. MEASUREMENTS AND MAIN RESULTS: The primary outcome measure was length of hospital stay. Secondary outcome measures were operating time, pain scores on postoperative days 1 and 7, and complication rates. There was no difference in length of hospital stay between the 2 arms. Compared with the 10LH group, the 5LH group had shorter operative times (32.6 vs 40 minutes; p = .01) and less postoperative pain on day 1 (2.5 vs 3.3; p = .03 for "pain with movement") and on day 7 (.92 vs 1.8; p = .002). Complication rates were similar between the 2 groups. CONCLUSION: TLH with a 5-mm laparoscope resulted in shorter operative times and less pain on postoperative days 1 and 7, compared with a 10-mm laparoscope, with similar length of stay and complications.

Use of robotic-assisted laparoscopic Mitrofanoff appendicovesicostomy in a paediatric patient: problem encountered.

This report is of robotic-assisted laparoscopic Mitrofanoff appendicovesicostomy in a 12-year-old patient with detrusor underactivity and hereditary sensory neuropathy. The whole operation was performed in 555 minutes with no open conversion. The patient experienced one episode of stomal stenosis, which required dilatation. At 3-year follow-up, the patient had both stomal and urinary continence. This is a safe and effective procedure to create a means of urinary catheterisation with avoidance of a large unsightly scar and comparable clinical outcome to an open procedure.

Utilization of a novel valveless trocar system during robotic-assisted laparoscopic prostatectomy.

PURPOSE: To evaluate the effect of a novel valveless trocar system (VTS) on perioperative outcomes in patients undergoing robotic-assisted laparoscopic prostatectomy (RALP). METHODS: A single-institution retrospective review was performed of 792 patients undergoing RALP. Preoperative patient variables, tumor characteristics, and perioperative variables were collected and analyzed. The first 150 patients were excluded from analysis to account for the learning curve of robotic surgery. Univariate and multivariate linear regression models were used to assess factors affecting operative time (ORT). RESULTS: A total of 257 and 385 patients underwent RALP utilizing the VTS and conventional insufflation, respectively. There were no significant differences in American Society of Anesthesiologist score, body mass index (BMI), prostate volume, final Gleason score, estimated blood loss, and complications between the cohorts. The only difference noted was a significantly shorter mean ORT in the VTS cohort (149.5 vs. 170.1 min, p < 0.0001). In light of this finding, further analysis was performed to identify associations with ORT. Multivariable analysis demonstrated that VTS, BMI, final Gleason score, prostate volume, surgeon, and node dissection were significantly associated with ORT. The use of the VTS decreased mean ORT by 23.2 min when controlling for confounding factors (p < 0.001). The performance of a nerve sparing operation was found to decrease ORT by 15.9 min (p < 0.001), though more often performed for lower-risk disease. CONCLUSION: The use of a novel VTS demonstrated decreased ORT in patients undergoing RALP when controlling for confounding factors. Prospective randomized trials are needed to evaluate its ultimate benefit in various surgical cohorts.

A survey of general surgeons regarding laparoscopic inguinal hernia repair: practice patterns, barriers, and educational needs.

PURPOSE: Practice patterns for inguinal hernia repair vary significantly among surgeons. The purpose of this study was to identify perceived indications for laparoscopic inguinal hernia repair (LIHR), and to identify barriers to its adoption and educational needs for surgeons. METHODS: A web-based survey was sent to general surgery members of several North American surgical societies, and to surgical residents through program directors. The 33-item survey was divided in 4 sections: demographics, utilization of techniques, management based on 11 clinical scenarios, reasons for not performing LIHR and educational needs for those who want to learn. RESULTS: Six hundred and ninety-seven general surgeons and 206 general surgery residents responded to the survey. Surgeons with MIS fellowships, and surgeons at the beginning of their careers are more likely to perform LIHR. Out of the 11 clinical scenarios, surgeons preferred a laparoscopic approach (totally extraperitoneal or transabdominal preperitoneal) for bilateral (48 %) and recurrent (44 %) hernias. However, 46 % of respondents never perform LIHR. Of these, 70 % consider the benefits of laparoscopy to be minimal, 59 % said they lack the requisite training, and 26 % are interested in learning. Surgeons (70 %) and residents (73 %) agreed that the best educational method would be a course followed by expert proctoring. CONCLUSION: Surgeons remain divided on the utility of laparoscopic surgery for inguinal hernia repair. Nearly half of responding surgeons never perform LIHR, and the other half offer it selectively. One quarter of surgeons who do not perform LIHR are interested in learning. This reveals a knowledge gap that could be addressed with educational programs.

Parasitic myoma after supracervical laparoscopic histerectomy.

Parasitic myoma is a condition defined as a myoma of extrauterine nourishing. It may occur spontaneously or as a consequence of surgical iatrogeny, after myomectomy or videolaparoscopic supracervical hysterectomy, due to remaining residues of uterine tissue fragments in the pelvic cavity after morcellation. The authors describe two cases in which the patients were submitted to videolaparoscopic supracervical hysterectomy and uterine body removal through morcellation. The sites of development of the parasitic myomas were next to the cervix stump in Case 1, and next to the right round ligament in Case 2. These parasitic myomas were removed by videolaparoscopy. After myomectomies or videolaparoscopic supracervical hysterectomies followed by uterine fragments removal from the pelvic cavity through morcellation, meticulous searching for residues or fragments of uterine tissue is mandatory to prevent the occurrence of parasitic myomas.

Laparoscopía y apendicectomía laparoscópica en niños: experiencia nacional / Laparoscopy and laparoscopic appendectomy in children: national experience

Introducción: la apendicitis aguda es la urgencia quirúrgica más frecuente en niños. Las dificultades diagnósticas determinan un porcentaje de apendicitis evolucionadas o de apendicectomías innecesarias. La morbilidad y la incidencia de estos eventos disminuye con la laparoscopía. Objetivo: presentar nuestra experiencia laparoscópica en niños, compararla con los trabajos internacionales y con la laparotomía en nuestro medio. Metodología: se realizó un trabajo retrospectivo de las laparoscopías diagnósticas (LD) y apendicectomías laparoscópicas (AL) en el período 2001-2009 . Se consideró: edad, sexo, tipo de apendicitis, tiempo quirúrgico, conversión, complicaciones, reintervención, estadía hospitalaria, antibioticoterapia, e histología. Se dividió la serie en un primer período de 50 apendicectomías en el que hubo criterios de exclusión, y un segundo de 75 en el que se desarrolló un aprendizaje tutorizado. Se compararon los dos períodos de la serie de AL entre sí, y la serie de AL con una serie local de apendicectomizados por vía abierta (AA). Las variables categóricas de interés se analizaron mediante test de Chi cuadrado, test de Fisher y test t de student, utilizando el programa Epi-info6. Resultados: se realizaron 164 procedimientos: 125 AL y 39 LD. Las primeras 50 AL se realizaron en 60 meses, y las 75 siguientes en 40. En el CHPR se realizaron 91 AL. La media de edad fue 10,2 (DE 1,9). Predominaron el sexo masculino (59%) y la apendicitis simple, que correspondió al 60,8% (76 casos). El índice de conversión en la serie fue de 4,8%, con disminución significativa (p=0,03) del primer período (10%) al segundo (1,3%). Hubo diferencia significativa (p de 0,002) en el tiempo quirúrgico entre el primer período (media 40’, DE 15,8) y el segundo (media 32’, DE 7,7). El índice de infección de la herida operatoria (IHO) en AL fue de 0,8% (un caso) y el de infección abdominal (IA) fue de 1,6% (dos casos)...

Introduction: acute appendicitis is the most common surgical emergency in children. The diagnostic difficulties determine a percentage of evolved appendicitis or unnecessary appendectomies. The morbidity and the incidence of these events diminishes with laparoscopy. Objective: to present our experience with laparoscopy in children, compared with international papers and laparotomy in our country.Method: we conducted a retrospective study of diagnostic laparoscopy (DL) and laparoscopic appendectomy (LA) in the period 2001-2009. Were considered: age, sex, type of appendicitis, surgical time, conversion, complications, reoperation, hospital stay, antibiotic therapy, and histology. We divided the series into a first period of 50 appendectomies in which there were exclusion criteria, and another 75 in which supervised learning was developed. We compared two periods of the AL series between themselves, and the number of AL with a local number with open appendectomy (AA). The categorical variables of interest were analyzed by Chi square, Fisher test and Student t test, using Epi-info 6.Results: 164 procedures were conducted: 125 AL and 39 LD. The first 50 were done in 60 months, and the following 75 in 40. The 91 were held CHPR AL. The mean age was 10.2 (SD 1.9). Males (59%) and simple appendicitis, which corresponded to 60.8% (76 cases), predominated. The conversion rate in the range was 4.8%, with significant reduction (p=0.03) from the first period (10%) to second (1.3%). There were significant reduction (p=0.002) in surgical time between the first period (average 40, DE 15.8) and second (mean 32', DE 7.7). The rate of surgical wound infection (SWI) in LA was 0.8% (one case) and abdominal infection (AI) was 1.6% (two cases). The AI and SWI in the series of AL was lower compared to the number of AA, with a significant reduction in SWI (p 0.001)...

Avaliação da utilização de sistema de suspensão abdominal mecânica: estudo experimental em cães / Evaluation of abdominal wall lifting system utilization: experimental study in dogs

Com o intuito de avaliar sistema de suspensão mecânica da parede abdominal, elaborou-se protocolo experimental, estudando-se trinta cães, distribuídos em três grupos experimentais de maneira aleatória: grupo pneumoperitônio com gás carbônico, grupo suspensão pela cavidade peritoneal e grupo suspensão abdominal (intraperitoneal) pela tela subcutânea, para documentar alterações metabólicas, hemodinâmicas e respiratórias em cada grupo, compará-las e verificar possíveis vantagens ou desvantagens dos métodos. Os animais foram monitorizados com eletrocardiograma, cateter de Swan-Ganz e pressão arterial invasiva, sendo colhidas amostras de sangue arterial e venoso misto nos momentos basal, 0, 15, 30, 60, 90, 120 minutos e 30 minutos após o término do procedimento, anotando-se para cada momento os parâmetros hemodinâmicos. Calculouse a média e o desvio padrão dos parâmetros, sendo os diferentes grupos comparados pelo teste de Kruskal-Wallis, e nos momentos em que se encontrou diferença estatística entre os três grupos, comparou-se os grupos dois a dois pelo teste de Mann-Whitney. Observou-se, no grupo pneumoperitônio em relação aos grupos suspensão, queda significativa do pH sangüíneo, elevação do bicarbonato, elevação da pressão venosa central e elevação da pressão parcial de gás carbônico, diferenças estas estatisticamente significativas, com p<0,05, não havendo diferenças estatísticas entre os grupos suspensão abdominal e subcutânea.

With the purpose of evaluate abdominal wall lifting system, a experimental protocol was elaborated, and thirty dogs, distributed randomly in three experimental groups, pneumoperitoneum with carbon dioxide gas, abdominal (intraperitoneal) suspension and subcutaneous suspension, were studied to document metabolic, hemodynamic and respiratory alterations, compare then and verify if there are some advantage or disadvantage in each method. The animals were monitored with electrocardiogram, Swan-Ganz catheter and invasive arterial blood pressure, and samples of arterial and venous blood were collected at the moments basal, 0, 15, 30, 60, 90 and 120 minutes, and 30 minutes after the end of procedure, registering at each moment the hemodynamical parameters. The three groups were statically compared with Kruskal-Wallis test and, at the moments with statistical differences, the groups were compared two by two with Mann-Whitney test. At the group pneumoperitoneum was observed significant decrease of blood pH, raising of bicarbonate, central venous pressure, and partial carbon dioxide blood pressure in relation to suspension groups, and those differences were statistically significant with p<0.05, without significant differences between abdominal and subcutaneous suspension groups.
