Standardized Surgical Primary Repair for Burst Abdomen Reduces the Risk of Fascial Redehiscence.

OBJECTIVE: To determine whether a standardized surgical primary repair for burst abdomen could lower the rate of fascial redehiscence. SUMMARY BACKGROUND DATA: Burst abdomen after midline laparotomy is associated with increased morbidity and mortality. The surgical treatment is poorly investigated but known for a poor outcome with high rates of re-evisceration (redehiscence). METHODS: This study was a single-center, interventional study comparing rates of fascial redehiscence after surgery for burst abdomen in a study cohort (July 2014-April 2019) to a historical cohort (January 2009-December 2013). A standardized surgical strategy was introduced for burst abdomen: The abdominal wall was closed using a slowly absorbable running suture in a mass closure technique with "large bites" of 3 cm in "small steps" of 5 mm, in an approximate wound-suture ratio of 1:10. Demographics, comorbidities, preceding type of surgery, and surgical technique were registered. The primary outcome was fascial redehiscence. The secondary outcome was 30- and 90-day mortality. RESULTS: The study included 186 patients with burst abdomen (92 patients in the historical cohort vs 94 patients in the study cohort). No difference in sex, performance status, comorbidity, or body mass index was found. In 77% of the historical cohort and 80% of the study cohort, burst abdomen occurred after emergency laparotomy (P = 0.664). The rate of redehiscence was reduced from 13% (12/92 patients) in the historical cohort to 4% (4/94 patients) in the study cohort (P = 0.033). There was no difference in 30- or 90-day mortality. CONCLUSION: Standardized surgical primary repair for burst abdomen reduced the rate of fascial redehiscence.

Closed incision negative pressure wound therapy may decrease wound complications in major lower extremity amputations.

OBJECTIVE: Wound complications after major lower extremity amputations (LEAs) are a cause of significant morbidity in vascular surgery patients. Recent publications have demonstrated the efficacy of the closed incision negative pressure dressing at preventing surgical site infections (SSIs); however, there are few data on its use in major LEAs. This study sought to assess if closed incision negative pressure wound therapy (NPWT) would decrease the risk of complications as compared with a standard dressing in patients with peripheral vascular disease undergoing major LEA. METHODS: Fifty-four consecutive patient limbs with a history of peripheral arterial disease underwent below-knee or above-knee amputations. This was a retrospective review of a prospectively maintained database from January 2018 to December 2019, and it included 23 amputations in the NPWT group and 31 amputations in the standard dressing group. NPWT using the PREVENA system was applied intraoperatively at the discretion of the operating surgeon and removed 5 to 7 days postoperatively. The standard group received a nonadherent dressing with an overlying compression dressing. Amputation incisions were assessed and wound complications were recorded. Student's t-test and two-sample proportion z-test were used for statistical analysis. A P value of less than .05 was considered statistically significant. RESULTS: For comorbidities, there was a higher incidence of tobacco use in the NPWT as compared with the standard group (44% vs 13%; P = .011), as well as trends toward increased prior amputations, anemia, hyperlipidemia, and chronic obstructive pulmonary disorder in the NPWT group. For risk factors, there were more dirty wounds in the NPWT as compared with the standard group (52% vs 26%; P = .046). For outcomes, there were fewer wound complications in the NPWT as compared with the standard group (13% vs 39%; P = .037). The types of wound-related complications in the NPWT group included one wound dehiscence with a deep SSI, one superficial SSI, and one incision line necrosis. In the standard group, there were four wound dehiscences with deep SSI, three superficial SSIs, four incision line necroses, and one stump hematoma. The rates of perioperative mortality and amputation revision did not differ significantly between the NPWT and the standard groups (3% vs 4% and 4.3% vs 10%, respectively). CONCLUSIONS: Closed incision NPWT may decrease the incidence of wound complications in vascular patients undergoing major LEA. This held true even among a population that was potentially at higher risk. This therapy may be considered for use in lower extremity major amputations.

Reducing Cesarean Delivery Surgical Site Complications.

Cesarean delivery (CD) wound complications disrupt the time a mother spends with her newborn. Surgical site infections (SSI) may result in unplanned office visits, emergency room visits, and hospital readmissions. Despite increasing attention to preoperative preparation, the CD SSI rate remains high. Local practices must be evaluated, and new methods to reduce CD SSI must be used.

Clinical outcome of V-Y flap with latissimus dorsi and gluteal advancement for treatment of large thoracolumbar myelomeningocele defects: a comparative study.

OBJECTIVE: Surgical repair and closure of myelomeningocele (MMC) defects are important and vital, as the mortality rate is as high as 65%-70% in untreated patients. Closure of large MMC defects is challenging for pediatric neurosurgeons and plastic surgeons. The aim of the current study is to report the operative characteristics and outcome of a series of Iranian patients with large MMC defects utilizing the V-Y flap and with latissimus dorsi or gluteal muscle advancement. METHODS: This comparative study was conducted during a 4-year period from September 2013 to October 2017 in the pediatric neurosurgery department of Shiraz Namazi Hospital, Southern Iran. The authors included 24 patients with large MMC defects who underwent surgery utilizing the bilateral V-Y flap and latissimus dorsi and gluteal muscle advancement. They also retrospectively included 19 patients with similar age, sex, and defect size who underwent surgery using the primary or delayed closure techniques at their center. At least 2 years of follow-up was conducted. The frequency of leakage, necrosis, dehiscence, systemic infection (sepsis, pneumonia), need for ventriculoperitoneal shunt insertion, and mortality was compared between the 2 groups. RESULTS: The bilateral V-Y flap with muscle advancement was associated with a significantly longer operative duration (p < 0.001) than the primary closure group. Those undergoing bilateral V-Y flaps with muscle advancement had significantly lower rates of surgical site infection (p = 0.038), wound dehiscence (p = 0.013), and postoperative CSF leakage (p = 0.030) than those undergoing primary repair. The bilateral V-Y flap with muscle advancement was also associated with a lower mortality rate (p = 0.038; OR 5.09 [95% CI 1.12-23.1]) than primary closure. In patients undergoing bilateral V-Y flap and muscle advancement, a longer operative duration was significantly associated with mortality (p = 0.008). In addition, surgical site infection (p = 0.032), wound dehiscence (p = 0.011), and postoperative leakage (p = 0.011) were predictors of mortality. Neonatal sepsis (p = 0.002) and postoperative NEC (p = 0.011) were among other predictors of mortality in this group. CONCLUSIONS: The bilateral V-Y flap with latissimus dorsi or gluteal advancement is a safe and effective surgical approach for covering large MMC defects and is associated with lower rates of surgical site infection, dehiscence, CSF leakage, and mortality. Further studies are required to elucidate the long-term outcomes.

Complications in cardiac surgery: An analysis of factors contributing to sternal dehiscence in patients who underwent surgery between 2010 and 2014 and a comparison with the 1990-2009 cohort.

BACKGROUND: Sternal dehiscence is a serious postoperative complication of cardiac surgery observed in 0.2-5% of procedures performed by median sternotomy. OBJECTIVES: Assessment of factors, including the method of sternum closure, which may affect the incidence of this complication. MATERIAL AND METHODS: A total of 5,152 consecutive patients undergoing surgery with median sternotomy access in the Cardiac Surgery Department of the Pomeranian Medical University between 2010 and 2014 were included in the study. The analysis centered on cases of sternal dehiscence, which occurred in 45 patients (0.9%). RESULTS: Factors such as age (p < 0.05), body mass (p < 0.005) and coronary artery bypass surgery (CABG) (p < 0.005) were found to be significant risk factors. Diabetes and chronic obstructive pulmonary disease (COPD) also had an impact on an increased risk of sternal dehiscence (p < 0.006 and p < 0.015). However, the differences were only significant in the whole study group. Apart from CABG, the type of operation did not affect the incidence of dehiscence. Logistic regression analysis found independent risk factors for the development of sternal dehiscence: body mass index (BMI) (odds ratio (OR): 2.1; p < 0.019), diabetes (OR: 2.4; p < 0.004), COPD (OR: 2.7; p < 0.016), and redo procedure (OR: 3.0; p < 0.014). There were no significant differences in postoperative mortality between these groups - 6.7% in the group with sternal dehiscence and 3.9% in the group without dehiscence. CONCLUSIONS: Introducing a more durable sternum stabilization method with 8+ loops helped to improve conditions for bone union and reduced the risk of dehiscence. Therefore, we suggest that centers which still use 6-loop sternal closure should consider shifting to a stronger technique.

Evaluación de factores de riesgo asociados a dehiscencia anastomótica en cirugía colorrectal: análisis multivariado de 748 pacientes / Evaluation of the risk factors associated with anastomotic dehiscence in colorectal surgery: multivariate analysis of 748 pacients

INTRODUCCIÓN: La dehiscencia anastomótica (DA) es una complicación severa en cirugía colorrectal con una incidencia que oscila entre 2 y 19%. La literatura internacional muestra numerosos estudios sobre la identificación de factores de riesgo (FR), mientras que en la nacional existen solo dos series que analizan esta complicación. OBJETIVO: Realizar una caracterización descriptiva de resultados institucionales y establecer la tasa de DA, sus factores de riesgo asociados y la mortalidad. MATERIALES Y MÉTODO: Serie de casos no concurrente, cuya muestra son pacientes consecutivos intervenidos de patología colorrectal con anastomosis primaria con o sin ostoma derivativo entre los años 2004 y 2016. Se realiza modelo de regresión logística univariable y multivariable. RESULTADOS: Se obtuvieron 748 pacientes, 50,5% mujeres, media de edad fue 56,2. Las indicaciones quirúrgicas más frecuentes fueron cáncer colorrectal en 381 (50,9%) pacientes y enfermedad diverticular en 163 (21,8%). La DA fue de 5,6% (42/748) y la mortalidad fue de 2% (15/748), siendo de 1% para los electivos (7/681). En el análisis univariado encontramos que los FR que tuvieron significancia estadística fueron la albúmina (p < 0,001), altura anastomosis (p < 0,001), transfusión (p < 0,001), localización (colon derecho > izquierdo) (p = 0,011), mientras que en el análisis multivariado fueron la albúmina (p = 0,002) con un OR 3,64 (IC 95% 1,58-8,35) y transfusión (p = 0,015) con un OR 7,15 (IC 95% 1,46-34,91). CONCLUSIÓN: Nuestra serie es la más grande reportada en Chile, con resultados similares a estudios internacionales y nacionales. Establecemos que la hipoalbuminemia y la presencia de transfusiones intraoperatorias se asocian a alta tasa de DA.

INTRODUCTION: Anastomotic leakage (AL) is a severe complication in colorectal surgery, its incidence ranges from 2 to 19%. In international literature, we found numerous studies on the identification of risk factors (RF), while in the national there are only two series that analyze this complication. AIM: Perform a descriptive characterization of institutional results and establish the AL rate, its associated risk factors and mortality. MATERIALS AND METHOD: Non-concurrent series of cases, whose sample is consecutive patients operated for colorectal pathology with primary anastomosis with or without a derivative ostoma between 2004 and 2016. Univariate and multivariable logistic regression model was performed. RESULTS: There were 748 patients, 50.5% women, mean age was 56.2. The most frequent surgical indications were colorectal cancer in 381 (50.9%) patients and diverticular disease in 163 (21.8%). The AL was 5.6% (42/748) and the mortality was 2% (15/748), being 1% for the electives (7/681). In the univariate analysis, we found that the RF that had statistical significance were albumin (p < 0.001), anastomosis height (p < 0.001), transfusion (p < 0.001), location (right colon > left) (p = 0.011), while that in the multivariate analysis were albumin (p = 0.002) with an OR 3.64 (IC 95% 1.58-8.35) and transfusion (p = 0.015) with an OR 7.15 (IC 95% 1.46-34.91). CONLUSION: Our series is the largest reported in Chile, with similar results to international and national studies. We establish that hypoalbuminemia and the presence of intraoperative transfusions are associated with a high rate of AL.

Prophylactic, Synthetic Intraperitoneal Mesh Versus No Mesh Implantation in Patients with Fascial Dehiscence.

BACKGROUND: Primary closure of post-operative facial dehiscence (FD) is associated with a high incidence of recurrence, revisional surgery, and incisional hernia. This retrospective study compares outcomes of implantation of non-absorbable intra-abdominal meshes with primary closure of FD. The outcomes of different mesh materials were assessed in subgroup analysis. METHODS: A total of 119 consecutive patients with FD were operated (70 mesh group and 49 no mesh group) between 2001 and 2015. Primary outcome parameter was hernia-free survival. Secondary outcome parameters include re-operations of the abdominal wall, intestinal fistula, surgical site infections (SSI), and mortality. Kaplan-Meier analysis for hernia-free survival, adjusted Poisson regression analysis for re-operations and adjusted regression analysis for chronic SSI was performed. RESULTS: Hernia-free survival was significantly higher in the mesh group compared to the no mesh group (P = 0.005). Fewer re-operations were necessary in the mesh group compared to the no mesh group (adjusted incidence risk ratio 0.44, 95% confidence interval [CI] 0.20-0.93, P = 0.032). No difference in SSI, intestinal fistula, and mortality was observed between groups. Chronic SSI was observed in 7 (10%) patients in the mesh group (n = 3 [6.7%] with polypropylene mesh and 4 [28.6%] with polyester mesh). The risk for chronic SSI was significantly higher if a polyester mesh was used when compared to a polypropylene mesh (adjusted odds ratio 8.69, 95% CI 1.30-58.05, P = 0.026). CONCLUSION: Implantation of a polypropylene but not polyester-based mesh in patients with FD decreases incisional hernia with a low rate of mesh-related morbidity.

[Patient-unrelated Risk Factors for the Development and Treatment Course of Anastomotic Failure in Colorectal Surgery - Results of Structured M+M Conferences]. / Nicht patientenbezogene Risikofaktoren für Entstehung und Behandlungsverlauf einer Anastomoseninsuffizienz nach Kolonresektion ­ Ergebnisse einer strukturierten M+M-Konferenz.

BACKGROUND: There are numerous published studies on patient-related risk factors for the development of anastomotic failure. We therefore investigated the influence of patient-unrelated risk factors for the development and course of treatment of anastomotic failure in colorectal surgery. PATIENT SAMPLE: From May 1, 2015, until December, 31, 2016, n = 179 post-colorectal surgery patients were analysed. Overall, n = 14 patients suffered from anastomotic failure. These patients' course of treatment was analysed in a Morbidity and Mortality Conference (M+M conference) structured according to the London Protocol. RESULTS: Irregularities in process quality were the most frequent analysis result (n = 8/14), followed by irregularities in post-treatment (n = 6/14). Irregularities in surgical technique (n = 2/14) and surgery procedure (n = 3/14) were less frequent. Future treatment approaches were identified for most patients (n = 11/14). On the basis of the analysis of data from four of these eleven patients, the strategy for future treatment was modified. CONCLUSION: Therapist- and environment-specific irregularities can be systematically identified in M+M conferences structured according to the London Protocol. This analysis is the prerequisite for quality improvement and must systematically complement the analysis of patient-related risk factors.

Application of Unilateral Pectoralis Major Muscle Flap in the Treatment of Sternal Wound Dehiscence.

OBJECTIVE: This study aims to report the use of the unilateral pectoralis major muscle flap for the treatment of the sternal wound dehiscence. METHODS: A retrospective study including patients who underwent unilateral pectoralis major muscle flap was performed for the treatment of sternotomy dehiscence due to coronary artery bypass, valve replacement, congenital heart disease correction and mediastinitis, between 1997 and 2016. Data from the epidemiological profile of patients, length of hospital stay, postoperative complications and mortality rate were obtained. RESULTS: During this period, 11 patients had their dehiscence of sternotomy treated by unilateral pectoralis major muscle flap. The patients had a mean age of 54.7 years, the mean hospital stay after flap reconstruction was 17.9 days (from 7 to 52 days). In two patients, it was necessary to harvest a flap from the rectus abdominis fascia, in association with the pectoralis major muscle flap, to facilitate the closure of the distal wound. In the postoperative period, seroma discharge from the surgical wound was observed in six patients, five reported intense pain (temporary), three had partial cutaneous dehiscence, and two presented granuloma of the incision. CONCLUSION: The complex wound from sternotomy dehiscences presents itself as a challenge to surgical teams. Treatment should include debridement of necrotic tissue and preferably coverage with well-vascularized tissue. We propose that the unilateral pectoralis major muscle flap is an interesting and low morbidity option for the reconstruction of sternal wound dehiscences, with proper sternum stability and satisfactory functional and aesthetic outcomes.

Triclosan-coated sutures for the prevention of surgical-site infections: a meta-analysis.

BACKGROUND: The scope of this article is to perform a meta-analysis of the studies that compare the use of triclosan-coated sutures (TCS) to uncoated sutures in prevention of surgical-site infections (SSIs). METHODS: A systematic search of randomized and non-randomized studies was carried out on Pubmed and Scopus databases until July 2016. RESULTS: The meta-analysis of 30 studies (19 randomized, 11 non-randomized; 15,385 procedures) gave evidence that TCS were associated with a lower risk of SSIs (risk ratio [RR] = 0.68; 95% confidence interval [CI] 0.57-0.81). Triclosan-coated sutures were associated with lower risk for SSIs in high-quality randomized studies (Jadad score 4 or 5). A lower risk for the development of SSIs based on wound classification was observed in clean, clean-contaminated, and contaminated but not for dirty procedures. No benefit was observed in specific types of surgery: colorectal, cardiac, lower limb vascular or breast surgery. Only a trend was found for lower risk for wound dehiscence, whereas no difference was observed for all-cause mortality. CONCLUSIONS: Further randomized studies are needed to confirm the role of TCS in specific surgical procedures and whether or not they are related with lower risk for mortality.

Open Abdomen Treated with Negative Pressure Wound Therapy: Indications, Management and Survival.

BACKGROUND: Open abdomen treatment (OAT) is a significant burden for patients and is associated with considerable mortality. The primary aim of this study was to report survival and cause of mortality after OAT. Secondary aims were to evaluate length of stay (LOS) in intensive care unit (ICU) and in hospital, time to abdominal closure and major complications. METHODS: Retrospective review of prospectively registered patients undergoing OAT between October 2006 and June 2014 at Trondheim University Hospital, Norway. RESULTS: The 118 patients with OAT had a median age of 63 (20-88) years. OAT indications were abdominal compartment syndrome (ACS) (n = 53), prophylactic (n = 29), abdominal contamination/second look laparotomy (n = 22), necrotizing fasciitis (n = 7), hemorrhage packing (n = 4) and full-thickness wound dehiscence (n = 3). Eight percent were trauma patients. Vacuum-assisted wound closure (VAWC) with mesh-mediated traction (VAWCM) was used in 92 (78 %) patients, the remaining 26 (22 %) had VAWC only. Per-protocol primary fascial closure rate was 84 %. Median time to abdominal closure was 12 days (1-143). LOS in the ICU was 15 (1-89), and in hospital 29 (1-246) days. Eighty-one (68 %) patients survived the hospital stay. Renal failure requiring renal replacement therapy (RRT) (OR 3.9, 95 % CI 1.37-11.11), ACS (OR 3.1, 95 % CI 1.19-8.29) and advanced age (OR 1.045, 95 % CI 1.004-1.088) were independent predictors of mortality in multivariate analysis. The nine patients with an entero-atmospheric fistula (EAF) survived. CONCLUSION: Two-thirds of the patients treated with OAT survived. Renal failure with RRT, ACS and advanced age were predictors of mortality, whereas EAF was not associated with increased mortality.

Predictors of wound dehiscence and its impact on mortality after abdominoperineal resection: data from the National Surgical Quality Improvement Program.

BACKGROUND: Wound dehiscence is a known complication following abdominoperineal resection (APR) and can have a negative impact on recovery and outcome. The aim of this study was to determine the predictors of post-APR 30-day abdominal and/or perineal wound dehiscence, readmission, and reoperation, and to assess the impact of wound dehiscence on 30-day mortality. METHODS: All patients undergoing APR between 2005 and 2012 were analyzed using the American College of Surgeons National Surgical Quality Improvement Program. RESULTS: There were 5161 patients [male = 3076 (59.6 %)] with a mean age of 61.9 ± 14.3 years. Mean body mass index was 27.4 ± 6.6 kg/m(2). The most common indication for surgery was rectal cancer (79.1 %), followed by inflammatory bowel disease (8.2 %). The overall rate of wound dehiscence was 2.7 % (n = 141). Older age (p = 0.013), baseline dyspnea (p = 0.043), smoking history (p = 0.009), and muscle flap creation (p ≤ 0.001) were independently associated with the risk of dehiscence. No association was observed between omental flap creation and dehiscence risk (p = 0.47). The 30-day readmission rate (15.6 vs. 5.6 %, p ≤ 0.001) and need for reoperation (39 vs. 6.6 %, p ≤ 0.001) were significantly higher in patients who experienced dehiscence. Dehiscence was an independent risk factor for 30-day mortality [OR = 2.69 (1.02-7.08), p = 0.045)]. CONCLUSIONS: Older age, baseline dyspnea, smoking, and the use of muscle flap were associated with higher risk of wound dehiscence following APR. Patients with wound dehiscence had a higher rate of readmission and need for reoperation, and an increased risk of 30-day mortality.

Thermoreactive nitinol clips: Propensity score comparison with Robicsek technique.

OBJECTIVE: To compare the use of thermoreactive nitinol clips with the classic Robicsek technique for treatment of sternal dehiscence after cardiac surgery. METHODS: Eighty-two (2.3%) of 3564 open heart surgery patients underwent reoperation for sternal dehiscence between October 2011 and 2012. Prospectively collected data from 26 (31%) consecutive patients who underwent reoperation using thermoreactive nitinol clips were compared with those of a retrospective cohort of 42 (51.2%) who were treated with the classic Robicsek technique. To overcome baseline and operative variations, we constructed a propensity model using logistic regression. RESULTS: Overall mortality occurred in 3 (5%) patients and a second revision was performed in 2 (7.7%) in the nitinol clip group and 2 (6.3%) in the control group (p > 0.05). Postoperative results were similar except for the mean time of operation which was significantly shorter in the nitinol clip group, and patients in this group required substernal dissection slightly less frequently than those in the control group. CONCLUSIONS: Thermoreactive nitinol clips allow the surgeon to perform a rapid and less challenging technique for sternal reoperations, without additional complications. Using this technique in an identical group with a finite sample size, we accomplished similar early results to those of the classic Robicsek technique.

Poststernotomy wound management by debridement and pedicle flaps reconstruction.

BACKGROUND: Sternal wound infection and sternal dehiscence are very serious, sometimes life-threatening complications of cardiac surgery, which require immediate attention. The mortality rate can reach 50%. During the past 30 years,various flaps for coverage of sternal wounds have been described. OBJECTIVE: The authors objective was to evaluate their 7-year experience with flaps used for coverage of poststernotomy wounds, with an emphasis on flap selection and post repair complications. RESULTS: The records of 15 patients were reviewed. The most common coverage techniques were pectoralis major flap (n=5)and rectus abdominis flap (n=4). Four patients had both of these flaps. One patient had a latissimus dorsi flap, and another one had an omental flap. Eight of the 15 patients experienced a local complication; these included seroma(n=2), hematoma (n = 1), infection requiring debridement and antibiotics (n = 2), partial flap necrosis (n = 2) and abdominal hernia (n=1). The perioperative mortality rate was 13.3% (n = 2), and all deaths were attributable to multiple organ deficiency due to sepsis. CONCLUSIONS: Early debridement and coverage of the remained defects with flaps are the two main principles in the management of poststernotomy infected wounds, especially insituations where rapid wound healing and recovery are extremely important. Individual approach to each patient and proper selection of the method of reconstruction significantly reduces the postoperative morbidity and mortality rate.

Incidence and mortality of anastomotic dehiscence requiring reoperation after rectal carcinoma resection.

Anastomotic dehiscence (AD) requiring reoperation is the most severe complication following anterior rectal resection. We performed a systematic review on studies that describe AD requiring reoperation and its subsequent mortality after anterior resection for rectal carcinoma. A systematic search was performed on published literature. Data on the definition and rate of AD, the number of ADs requiring reoperation, the mortality caused by AD, and the overall postoperative mortality were pooled and analyzed. A total of 39 studies with 24,232 patients were analyzed. The studies varied in incidence and definition of AD. Systematic review of the data showed that the overall rate of AD was 8.6%, and the rate of AD requiring reoperation was 5.4%. The postoperative mortality caused by AD was 0.4%, and the overall postoperative mortality was 1.3%. We found considerable risk and mortality for AD requiring reoperation, which largely contributed to the overall postoperative mortality.

Episiotomy and obstetric perineal wound dehiscence: beyond soreness.

Postpartum episiotomy dehiscence is a rare complication of vaginal delivery. Infection rates in episiotomy wounds are surprisingly low; however, it remains the most common cause of wound dehiscence, which may lead to major physical, psychological and social problems if left untreated. Most dehisced perineal wounds are left to heal naturally by secondary intention. This approach often results in a protracted period of significant morbidity for women. There is emerging evidence that early re-suturing closure of broken-down perineal wounds may have a better outcome, but randomised controlled trials are needed to yield evidence-based guidance for this management approach.

Wound dehiscence after abdominoperineal resection for low rectal cancer is associated with decreased survival.

BACKGROUND: Abdominoperineal resection for low rectal adenocarcinoma is a common procedure with high morbidity, including perineal wound complications. OBJECTIVE: The purpose of this study was to determine risk factors for perineal wound dehiscence and to investigate the effect of wound dehiscence on survival. DESIGN: This was a retrospective medical chart review. SETTINGS: The study was conducted in a tertiary care university medical center. PATIENTS: Patients included in the study were those with low rectal adenocarcinoma who underwent abdominoperineal resection between January 2001 and June 2012. MAIN OUTCOMES MEASURES: We assessed the incidence of perineal wound dehiscence, as well as survival, after surgery. RESULTS: A total of 249 patients underwent abdominoperineal resection for rectal carcinoma. The mean age was 62.6 years (range, 23.0-98.0 years), 159 (63.8%) were male, and the mean BMI was 27.9 (range, 16.7-58.5). There were 153 patients (61.1%) who survived for 5 years after surgery. Sixty-nine patients (27.7%) developed wound dehiscence. Multivariable analysis revealed the following associations with dehiscence: BMI (OR, 1.09; 95% CI, 1.03-1.15; p = 0.002), IBD (OR, 6.6; 95% CI, 1.4-32.5; p = 0.02), history of other malignant neoplasm (OR, 3.1; 95% CI, 1.5-6.6), and abdominoperineal resection for cancer recurrence (OR, 2.8; 95% CI, 1.2-6.3; p = 0.01). In the survival analysis, wound dehiscence was associated with decreased survival (mean survival time for dehiscence vs no dehiscence, 66.6 months vs 76.6 months; p = 0.01). This relationship persisted in the multivariable analysis (HR, 1.7; 95% CI, 1.1-2.8; p = 0.02). LIMITATIONS: This was a retrospective, observational study from a single center. CONCLUSIONS: The adjusted risk of death was 1.7 times higher in patients who experienced dehiscence than in those who did not. Attention to perineal wound closure with consideration of flap creation should at least be given to patients with a history of malignant neoplasm, those with IBD, those with rectal cancer recurrence, and women undergoing posterior vaginectomy. Preoperative weight loss should also reduce dehiscence risk.
