RESUMO

Objetivo: analisar o percentual de instrumentais cirúrgicos que compõem a caixa de laparotomia exploradora e não são utilizados durante as cirurgias. Método: estudo descritivo, transversal com abordagem quantitativa, que contabilizou instrumentais constituintes da caixa de laparotomia exploradora utilizados e não utilizados durante 13 cirurgias realizadas em um período de 17 dias, em um hospital do interior paulista. Resultados: nas 13 cirurgias analisadas, obteve-se um total de 1300 (100%) pinças presentes nas caixas, onde 832 (64%) não foram utilizadas e 468 (36%) foram utilizadas. Nos tempos cirúrgicos, o maior número de uso foi de 166 (35,5%) artigos, para preensão e afastadores. Conclusão: houve 64% de instrumentais não utilizados nas cirurgias analisadas. Há necessidade de implementar estratégias gerenciais que reduzam os números encontrados e, consequentemente, reduzam gastos, para gerar menor desperdício e reduzir falhas no gerenciamento de recursos materiais.


Objective: to analyze the percentage of surgical instruments that make up the operating laparotomy box and are not used during surgeries. Method: descriptive, cross-sectional study with quantitative approach, which counted instrumental constituents of the exploratory laparotomy box used and not used during 13 surgeries performed in a period of 17 days, in a hospital in the interior of São Paulo. Results: in the 13 surgeries analyzed, a total of 1300 (100%) tweezers were obtained in the boxes, where 832 (64%) were not used and 468 (36%) were used. In surgical times, the highest number of use was 166 (35.5%) articles, for seizures and reparators. Conclusion: there were 64% of instruments not used in the analyzed surgeries. There is a need to implement management strategies that reduce the numbers found and, consequently, reduce expenses, to generate less waste and reduce failures in the management of material resources.

RESUMO

BACKGROUND: Surgical site infection is a major surgical complication and has been studied extensively. However, the efficacy of changing surgical instruments before wound closure remains unclear. OBJECTIVE: The aim of this study was to investigate the efficacy of changing surgical instruments to prevent incisional surgical site infection during lower GI surgery. DESIGN: This was a randomized controlled trial. SETTINGS: This study was conducted at the Hyogo College of Medicine in Japan. PATIENTS: Patients undergoing elective lower GI surgery with open laparotomy were included. INTERVENTIONS: Patients were randomly assigned to 1 of 2 groups. In group A, the surgeon changed surgical instruments before wound closure, and in group B, the patients underwent conventional closure. MAIN OUTCOME MEASURES: The primary end point was the incidence of incisional surgical site infection. The secondary end point was the incidence of surgical site infection restricted to clean-contaminated surgery. RESULTS: A total of 453 patients were eligible for this trial. The incidence of incisional surgical site infection was not significantly different between group A (18/213; 8.5%) and group B (24/224; 10.7%; p = 0.78). In the clean-contaminated surgery group, the incidence of incisional surgical site infection was 13 (6.8%) of 191 in group A and 9 (4.7%) of 190 in group B (p = 0.51). LIMITATIONS: This was a single-center study. CONCLUSIONS: Changing surgical instruments did not decrease the rate of incisional surgical site infection in patients undergoing lower GI surgery in either all wound classes or clean-contaminated conditions.

RESUMO

OBJECTIVES: Recognize the avoidable costs incurred due to overpacking of rhinoplasty instrument trays. Reduce rhinoplasty instrument trays by including only instruments used frequently. Establish methods to reduce trays prepared for other otolaryngologic procedures. METHODS: This is a prospective study. The study evaluates the specific use of instruments opened for rhinoplasty procedures at the New York Eye & Ear Infirmary of Mount Sinai. Instruments were counted in 10 rhinoplasty cases. Usage rate was calculated for each instrument. Additionally, all instruments used in at least 20% of cases were noted. This "20%" threshold was used to create new rhinoplasty tray inventories more reflective of actual instrument usage. Some instruments above the 20% threshold were included in multiples (i.e. two Adson Brown forceps vs. one curved iris scissor). RESULTS: 189 instruments were opened, and 32 instruments were used on average in each rhinoplasty. 55 instruments were used in at least 20% of cases. The 55 "high usage" instruments were used to create new, reduced rhinoplasty tray inventory lists. Based on our analysis, a new rhinoplasty tray inventory was created comprised of 68 instruments, a 64% reduction from 189. CONCLUSION: Instruments are sterilized and packed in gross excess for rhinoplasty procedures. Previously published figures estimate re-sterilization costs of $0.51 to $0.77 per instrument. Reduction in instruments opened from 189 to 68 is expected to lead to cost savings ranging from $62 to $93 per case, yielding a savings between $6200 and $9300 per 100 cases performed. LEVEL OF EVIDENCE: II-3.

RESUMO

Operating Rooms (ORs) generate the largest revenues and losses in a hospital. Without the prompt supply of sterile surgical trays from the Sterile Processing Department (SPD), the OR would not be able to perform surgeries to its busy schedule. Nevertheless, little emphasis has been brought in the medical literature to research on surgical instrument processing in the medical literature. The present study was done applies an Enhanced Kaizen Event (EKE) in the SPD of a rural hospital to identify sources of waste and minimize non-value-added steps in the SPD processes. The EKE consisted of three successive Plan-Do-Check-Act (PDCA) cycles, which focused on improvements at the departmental level first, then at an area level, and finally at the station level. The EKE yielded an improved streamlined workflow and a new design for the SPD layout, one of its areas, and a workstation. This paper aims at building a methodology, including identified steps. Results exhibited a 35% reduction in travel distance by the staff, eliminating non-value-added processes, reducing errors in the sterilization process, and eliminating cross-contamination for sterilized materials.

RESUMO

Laparoscopic liver resection is a demanding procedure that is undergoing continuous development. The surgeon's skill is constantly improving, new surgical instruments are being introduced, and the indications for this procedure are expanding. However, there is still great concern about patient safety during the procedure and it is not commonly performed in many centers, although numerous studies have confirmed the safety and feasibility of laparoscopic liver techniques. Our center tries to use laparoscopy routinely for most cases and we do not consider conversion to open surgery to be a complication. We present our current opinion on patient selection for laparoscopic liver resection in the hope of encouraging more centers to adopt and develop this technique. Although laparoscopic liver resection is not an official standard of care, it should be considered according to the surgeon's experience and available resources.

RESUMO

BACKGROUND: Colonic transendoscopic enteral tubing (TET) refers to colonic transendoscopic tube-delivered enteral therapy. Colonic TET has been successfully used for frequent colonic administration of drugs or multiple fecal microbiota transplantations (FMTs). This prospective observational study aimed to evaluate possible factors affecting methodology, feasibility and safety of colonic TET. METHODS: Patients who underwent colonic TET at our center from October 2014 to November 2018 were included. The feasibility, efficacy, and safety of TET were evaluated. RESULTS: In total, 224 patients were analyzed. The success rate of TET was 100%. The median retention time of TET tube within the colonic lumen was 8.5 (IQR 7-11) days in 158 patients with tube falling out spontaneously, and the maximum retention time was up to 28 days. These patients were divided into the short-retention group (≤ 8.5 days) and the long-retention group (> 8.5 days). Univariate and multivariate analysis demonstrated that the type of endoscopic clip (p = 0.001) was an independent factor for the retention time. The larger clips as well as a greater number of clips significantly affected the retention time (p = 0.013). No severe adverse event was observed during and after TET. CONCLUSIONS: Colonic TET is a feasible, practical, and safe colon-targeted drug delivery technique with a high degree of patients' satisfaction. Two to four large endoscopic clips are recommended to maintain stability of the TET tube within the colon for over 7 days.

RESUMO

OBJECTIVE: To describe incidents of retained surgical items, including their characteristics and the circumstances in which they occur. DESIGN: A qualitative content analysis of root cause analysis investigation reports. SETTING: Public health services in Victoria, Australia, 2010-2015. PARTICIPANTS: Incidents of retained surgical items as described by 31 root cause analysis investigation reports. MAIN OUTCOME MEASURE(S): The type of retained surgical item, the length of time between the item being retained and detected and qualitative descriptors of the contributing factors and the circumstances in which the retained surgical items occurred. RESULTS: Surgical packs, drain tubes and vascular devices comprised 68% (21/31) of the retained surgical items. Nearly one-quarter of the retained surgical items were detected either immediately in the post-operative period or on the day of the procedure (7/31). However, about one-sixth (5/31) were only detected after 6 months, with the longest period being 18 months. Contributing factors included complex or multistage surgery; the use of packs not specific to the purpose of the surgery; and design features of the surgical items. CONCLUSION: Retained drains occurred in the post-operative phase where surgical counts are not applicable and clinician situational awareness may not be as great. Root cause analysis investigation reports can be a valuable means of characterizing infrequently occurring adverse events such as retained surgical items. They may detect incidents that are not detected by other data collections and can inform the design enhancements and development of technologies to reduce the impact of retained surgical items.

RESUMO

The Clutch Cutter was invented as a scissor-type knife for endoscopic submucosal dissection (ESD) of gastrointestinal neoplasms. ESD with the scissor-type knife (ESD-S) may be considered a technically easier procedure than ESD with non-scissor-type knives (ESD-NS). Therefore, this study aimed to compare the technical outcomes of ESD-S with those of ESD-NS for superficial esophageal cancer. This was a multicenter retrospective study. Patients with superficial esophageal cancer treated with ESD between October 2015 and March 2018 at three hospitals were retrospectively reviewed. The ESD-S group had 48 patients and the ESD-NS group had 114 patients. A propensity score matching analysis was performed to compensate for the confounding bias between both groups. Multivariate analyses and propensity score matching were used to adjust for age, sex, the tumor size, tumor location, tumor depth, degree of tumor circumference, operator level, usage of the traction method, and the sedation method. The primary outcome was the procedure time of the ESD. Secondary outcomes were the rate of en-bloc/complete resection and the rate of complications including perforation, delayed bleeding, and stricture. Propensity score matching analysis provided 36 matched pairs. Median procedure time in the ESD-S group was significantly shorter than that in the ESD-NS group (44.0 min vs. 66.5 min, P = 0.020). In addition, the treatment outcomes were similar in both groups (en-bloc resection: 100% vs. 97.2%, P = 1; complete resection: 88.9% vs. 86.1%, P = 1; curative resection: 80.6% vs. 77.8%, P = 1; perforation: 0% vs. 5.6%, P = 0.49; delayed bleeding: 0% in both groups; stricture: 2.8% vs. 8.3%, P = 0.61). ESD-S was associated with a shorter procedure time than ESD-NS, without an increase in the incidence of complications. Therefore, the scissor-type knife should be considered as an endo-knife for ESD of superficial esophageal cancers.

RESUMO

BACKGROUND: Bar code- or radio frequency identification (RFID)-based medical instrument management systems have gradually been introduced in the field of surgical medicine for the individual management and identification of instruments. We hypothesized that individual management of instruments using RFID tags can provide previously unavailable information, particularly the precise service life of an instrument. Such information can be used to prevent medical accidents caused by surgical instrument failure. This study aimed to predict the precise service life of instruments by analyzing the data available in instrument management systems. METHODS: We evaluated the repair history of instruments and the usage count until failure and then analyzed the data by the following three methods: the distribution of the instrument usage count was determined, an instrument failure probability model was generated through logistic regression analysis, and survival analysis was performed to predict instrument failure. RESULTS: The usage count followed a normal distribution. Analysis showed that instruments were not used uniformly during surgery. In addition, the Kaplan-Meier curves plotted for five types of instruments showed significant differences in the cumulative survival rate of different instruments. CONCLUSIONS: The usage history of instruments obtained with RFID tags or bar codes can be used to predict the probability of instrument failure. This prediction is significant for determining the service life of an instrument. Implementation of the developed model in instrument management systems can help prevent accidents due to instrument failure. Knowledge of the instrument service life will also help in developing a purchase plan for instruments to minimize wastage.

RESUMO

Minimally invasive mitral valve surgery has become routine in many institutions. Disadvantages of this approach include prolonged aortic cross-clamp and cardiopulmonary bypass times. Mitral valve replacement with a continuous suture technique may reduce operative times. We present a case of a 51-year-old man suffering from severe rheumatic mitral disease to highlight our continuous suture technique for minimally invasive mitral valve replacement. We also report preliminary results from our series of 15 patients suffering various rheumatic mitral pathology treated with this technique.

RESUMO

BACKGROUND: Retained suture material from primary Roux-en-Y gastric bypass or revisions may result in local inflammation, ulcer formation, and abdominal pain. The primary aim of this study was to evaluate the feasibility, efficacy, and safety of novel, disposable endoscopic scissors for suture removal. METHODS: This was a single-center, retrospective analysis of prospectively collected data from December 2016 to January 2019. Patients with history of Roux-en-Y gastric bypass and upper endoscopy utilizing this novel, disposable endoscopic scissors device were reviewed. Measured outcomes included endoscopy indication, technical success (as determined by ability to achieve adequate cut and suture removal), improvement in abdominal pain if present prior to procedure, and adverse events. RESULTS: Sixty-two patients were included in this analysis. Mean age was 54.69 ± 9.40 years. Eighty-eight percent of patients were female. Roux-en-Y gastric bypass occurred on average 142.43 ± 62.33 months prior to suture removal. Primary indications for endoscopy were evaluation of gastric pouch and gastrojejunal anastomosis for weight regain (37.10%) and abdominal pain (30.65%). Overall, technical success of these novel endoscopic scissors was 100% with a mean procedure duration of 23.00 ± 9.50 min. Symptom improvement post-suture removal occurred in approximately half of the patients (48.65%). Post-procedure bleeding was self-limited and occurred in 2 patients (3.23%). Two patients developed transient post-procedure abdominal pain. CONCLUSIONS: Novel, disposable endoscopic scissors appear to be highly effective and safe for removal of suture material with high technical success and minimal adverse events.

RESUMO

BACKGROUND: The surgical microscope is used primarily for microsurgeries, which are more complicated than other surgical procedures and require delicate tasks for a long time. Therefore, during these surgical procedures, surgeons experience back and neck pain. To solve this problem, new technology, such as wearable displays, is required to help surgeons maintain comfortable postures and enjoy advanced functionality during microsurgery. OBJECTIVE: The objective of this study was to develop a surgical microscope system that would work with wearable devices. It would include a head-mounted display (HMD) that can offer 3D surgical images and allow a flexible and comfortable posture instead of fixed eyepieces of surgical microscope and can also provide peripheral visual field with its optical see-through function. METHODS: We designed and fabricated a surgical microscope system that incorporates a see-through type 3D HMD, and we developed an image processing software to provide better image quality. The usability of the proposed system was confirmed with preclinical examination. Seven ENT (ear, nose, and throat) surgical specialists and 8 residents performed a mock surgery-axillary lymph node dissection on a rat. They alternated between looking through the eyepieces of the surgical microscope and viewing a 3D HMD screen connected to the surgical microscope. We examined the success of the surgery and asked the specialists and residents to grade eye fatigue on a scale of 0 (none) to 6 (severe) and posture discomfort on a scale of 1 (none) to 5 (severe). Furthermore, a statistical comparison was performed using 2-tailed paired t test, and P=.00083 was considered significant. RESULTS: Although 3D HMD case showed a slightly better result regarding visual discomfort (P=.097), the average eye fatigue was not significantly different between eyepiece and 3D HMD cases (P=.79). However, the average posture discomfort, especially in neck and shoulder, was lower with 3D HMD display use than with eyepiece use (P=.00083). CONCLUSIONS: We developed a see-through type 3D HMD-based surgical microscope system and showed through preclinical testing that the system could help reduce posture discomfort. The proposed system, with its advanced functions, could be a promising new technique for microsurgery.

RESUMO

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.

RESUMO

BACKGROUND: Although many studies investigated the accuracy of customized cutting block (CCB), the data on rotational alignment are still lacking. The study aimed to assess whether CCB improved the component rotational position compared with conventional cutting instrument (CCI) using computed tomography scanning. METHODS: Eighty-six of 102 total knee arthroplasties from the previous randomized study were analyzed. The outcomes were rotational position of the femoral and tibial components, frequency of outliers and intra-class correlation coefficient. RESULTS: The mean femoral component rotation was not different between CCB versus CCI: 0.9° ± 0.8° versus 1.1° ± 1.1° (P = 0.29). Both groups had similar outlier frequencies: 2% (CCB) versus 2% (CCI) (P = 0.74). CCB had nearly 1° less mean tibial component deviation compared with CCI (P < 0.001): (1) dorsal tangent reference (DTR): 0.7° ± 0.8° versus 1.5° ± 1.0°, and (2) tibial trans-epicondylar reference (TTR): 0.5° ± 0.9° versus 1.4° ± 1.1°. Outlier frequencies were similar: (1) DTR: 0% CCB versus 5% CCI (P = 0.24), and (2) TTR: 5% in CCB versus 12% CCI (P = 0.20). Measurements based on tibial tubercle showed that CCB had ~ 1.4° less mean tibial component deviation compared with CCI: 0.3° ± 1.4° versus 1.7° ± 1.6° (P < 0.001) with a corresponding, less frequency of outliers: 0% versus 19% (P = 0.002). However, there was poor intra-observer reproducibility (0.61). CONCLUSIONS: CCB did not improve femoral component rotational alignment compared with CCI nor affect outlier frequency, but it marginally improved the accuracy of tibial rotational alignment. The tibial tubercle reference point had poor intra-observer reproducibility.

RESUMO

Importance: Although several studies have reported data on surgical aortic valve durability, variability in study methodologies and definitions as well as inadequate follow-up make the interpretation of data from these studies difficult to interpret. Objective: To review available data on structural valve deterioration (SVD) of surgical bioprosthetic aortic valves by examining the published literature as well as data reported to the US Food and Drug Administration (FDA). Evidence Review: A systematic review using Preferred Reporting Items for Systematic Review and Meta-Analysis reporting guidelines to obtain all available data from preexisting literature on the actuarial freedom from SVD and outcomes of SVD. Data were collected from database inception to November 2016. Additionally, data reported to the FDA were obtained. Findings: In total, 167 studies and 12 FDA reports including 101 650 patients and 17 different valve types were analyzed. There were 11 different definitions of SVD used in the studies. Core laboratory data were available for 11 studies. Mean follow-up ranged from less than 1 year to 14 years. Kaplan-Meier estimates were reported for up to 30 years of follow-up, with 0% to 37% of patients remaining at risk at maximum follow-up. Food and Drug Administration-reported data are similarly variable in duration (mean follow-up range, 1.2 to 7 years) and completeness of follow-up, with final follow-up of 0.1% to 95%. Conclusions and Relevance: There is considerable variability in reporting SVD of surgical aortic valves, with different definitions and inadequate long-term systematically collected core laboratory data. Rigorously collected long-term data with standardized definitions for surgical valves are needed to provide a benchmark for the durability of rapidly evolving transcatheter valves.

RESUMO

BACKGROUND: Right-sizing instrument trays reduce processing and replacement costs, physical strain, and turnover times. Historically, a 98-instrument head and neck tray has been used for breast lumpectomy cases at our institution. Observations revealed that many instruments on the tray were not used during the breast cases. With the significant number of surgical breast lumpectomies performed annually, tray downsizing could significantly reduce costs and physical strain. METHODS: Surgical technicians identified instruments needed for a standard breast lumpectomy. Breast surgeons reviewed the list and made final recommendations. Three of 13 existing head and neck trays were converted to breast lumpectomy trays. The number of breast lumpectomies in 2017 was pulled from the institution's health information system. Instrument quantities were verified using instrument management software. Weights were taken on a digital scale, and processing cost was estimated by a consultant. RESULTS: The new breast trays included 51 instruments rather than the standard 98-instrument trays. Reprocessing cost decreased from $49.98 to $26.01. With 449 breast lumpectomies performed at the institution in 2017, the annual reprocessing savings totaled $10,763. The tray weight was reduced from 27 to 16 pounds. Setup time decreased from 7 to 4 min per use (22.5 h saved annually). CONCLUSIONS: Downsizing from a head and neck tray to a specific breast lumpectomy tray demonstrated a reduction in reprocessing cost, tray weight, and setup time. Lighter trays allow for safer handling and transport by surgical personnel. In the current health-care environment, it is important to maximize operating room efficiency and minimize cost.

RESUMO

Objective: To verify the relationship between the time of clamping of the umbilical cord and the development of neonatal jaundice, the dosage of bilirubin and the need for phototherapy. Methods: Cross-sectional, retrospective study with 398 parturients at normal risk (single term gestation, no complications during gestation or delivery, birth weight between 2500 and 4499 g). The population was divided into three groups regarding the time of cord clamping: <1 min(117, 29.4%), between 1 and 3 min(228, 57.3%) and >3 min(53, 13.3%). Sociodemographic, clinical and obstetric characteristics, birth and delivery data, and maternal and perinatal outcomes were evaluated. Pearson's chi-square test, Fisher's exact test and the Kruskal-Wallis test were used for comparison between the groups. Statistical significance was considered p < .05. Results: The groups were similar in the development of jaundice (p = .370), bilirubin dosage (p = .342) and need for phototherapy (p = .515). Late clamping was more prevalent in vaginal deliveries when compared to cesarean sections (1-3 min: 64 versus 21.4%, >3 min: 16.6 versus 1%) (p < .001). There was no difference in other maternal or perinatal variables. Conclusion: The clamping time of the umbilical cord showed no association with jaundice, bilirubin dosage, or phototherapy needs in neonates at normal risk. The adoption of late clamping was more prevalent in vaginal deliveries.

RESUMO

ABSTRACT Background: The surgical treatment of anal fistula is complex due to the possibility of fecal incontinence. Fistulotomy and cutting Setons have the same incidence of fecal incontinence depending on the complexity of the fistula. Sphincter-preserving procedures such as anal fistula plug and ligation of intersphincteric fistula tract procedure may result in more recurrence requiring repeated operations. The aim of this study was to evaluate and compare the outcomes of treating fistula in Ano utilizing two methods: Fistula plug (Gore Bio-A) and ligation of intersphincteric tract (LIFT). Methods: Fifty four patients (33 males; 21 female, median ages 42 [range 32-47] years) with high anal inter-transphenteric fistula were treated with LIFT and fistula plug procedures from September 2011 until August 2016 by a single surgeon and were retrospectively evaluated. All were followed for a median of 23.9 (range 4-54) months with clinical examination. Twenty one patients underwent fistula plug and 33 patients underwent LIFT procedure (4 patients of the LIFT group underwent LIFT and rectal mucosa advancement flap). The healing rate and complications were evaluated clinically and through telephone calls. Results: The mean operative time for the Plug was 25 ± 17 min and for the LIFT was 40 ± 20 min (p = 0.017) and the mean hospital stay was 2.4 ± 1.1 and 1.9 ± 0.3 (p = 0.01) respectively. The early complications of the plug and LIFT procedures included; anal pain (33.3%, 66.6%, p = 0.13), perianal discharge (77.8%, 91%, p = 0.62), anal pruritus (38.9%, 50.0%, p = 0.71) and bleeding per rectum (16.7%, 33.3%, p = 0.39) respectively. The overall mean follow-up was 20.9 ± 16.8 months, p = 0.68. There was no statistically significant difference between the two groups (21.9 ± 7.5 months, 19.9 ± 16.1 months, p = 0.682). The healing rate was 76.2% (16/21 patients) in the fistula plug group and 81.1% (27/33 patients) in the LIFT group (p = 0.73). Patients who had LIFT procedure and a mucosal advancement flap had 100% healing rate (4 out of 4 patients). No incontinence of stool or feces and no fistula plug expulsion were seen in our patients. The healing time ranged from 1 to 6 months after surgery. There was no post-operative perianal abscess, cellulitis or pain. Conclusions: LIFT and anal plug are safe procedures for patients with primary and recurrent anal fistula. Both techniques showed excellent results in terms of healing and complication rate. None of our patients had incontinence after 5 years follow-up. The best success rate in our patients was seen after LIFT procedure with mucosal advancement flap. Larger and controlled randomized trials are needed for better assessment of treatment options.


RESUMO Introdução: O tratamento cirúrgico da fístula anal é complexo devido à possibilidade de incontinência fecal. A fistulotomia e o seton de corte têm a mesma incidência da incontinência fecal, dependendo da complexidade da fístula. Procedimentos de preservação do esfíncter, como o tampão da fístula anal e o procedimento LIFT (ligadura do trato da fístula interesfincteriana), podem resultar em mais recorrência, exigindo cirurgias repetidas. O objetivo deste estudo foi avaliar e comparar os desfechos do tratamento da fístula anal utilizando dois métodos: Tampão de fístula (Gore Bio-A) e Ligadura do Trato Interesfincteriano (LIFT). Métodos: Cinquenta e quatro pacientes (33 homens; 21 mulheres, com mediana de idade de 42 [variação 32-47] anos) foram tratados com LIFT e procedimentos com tampão de fístula de setembro de 2011 até agosto de 2016 por um único cirurgião e foram avaliados retrospectivamente. Todos foram acompanhados por uma mediana de 23,9 (variação de 4 a 54) meses com exame clínico. Vinte e um pacientes foram submetidos a tampão de fístula e 33 pacientes foram submetidos ao procedimento LIFT (4 pacientes do grupo LIFT foram submetidos a LIFT e retalho de avanço da mucosa retal). A taxa de cicatrização e as complicações foram avaliadas clinicamente e por meio de ligações telefônicas. Resultados: O tempo cirúrgico médio para o Tampão foi de 25 ± 17 minutos e para o LIFT foi de 40 ± 20 minutos (p = 0,017) e o tempo médio de internação foi de 2,4 ± 1,1 e 1,9 ± 0,3 (p = 0,01), respectivamente. As primeiras complicações dos procedimentos de tampão e LIFT incluíram: dor anal (33,3%, 66,6%, p = 0,13), secreção perianal (77,8%, 91%, p = 0,62), prurido anal (38,9%, 50,0%, p = 0,71) e sangramento pelo reto (16,7%, 33,3 %, p = 0,39) respectivamente. A média geral de acompanhamento foi de 20,9 ± 16,8 meses, p = 0,68. Não houve diferença estatisticamente significativa entre os dois grupos (21,9 ± 7,5 meses, 19,9 ± 16,1 meses, p = 0,682). A taxa de cicatrização foi de 76,2% (16/21 pacientes) no grupo com tampão de fístula e 81,1% (27/33 pacientes) no grupo LIFT (p = 0,73). Pacientes submetidos ao procedimento LIFT e um retalho de avanço da mucosa tiveram 100% de taxa de cura (4 de 4 pacientes). Nenhuma incontinência fecal e nenhuma expulsão do tampão da fístula foram observadas em nossos pacientes. O tempo de cicatrização variou de 1 a 6 meses após a cirurgia. Não houve abscesso perianal, celulite ou dor no pós-operatório. Conclusões: LIFT e tampão anal são procedimentos seguros para pacientes com fístula anal primária e recorrente. Ambas as técnicas apresentaram excelentes resultados em termos de cicatrização e taxa de complicações. Nenhum de nossos pacientes teve incontinência após 5 anos de acompanhamento. A melhor taxa de sucesso em nossos pacientes foi observada após o procedimento LIFT com retalho de avanço da mucosa. Ensaios clínicos randomizados de maior porte e controlados são necessários para melhor avaliação das opções de tratamento.
