Negative-Pressure Wound Therapy to Reduce Wound Complications after Abdominoperineal Resection

The effect of incisional negative pressure wound therapy on the improvement of postoperative cosmetic suture wounds and scar hyperplasia

This study aimed to explore the effects of early incisional negative pressure wound therapy (INPWT) on cosmetic suture wounds and postoperative scar hyperplasia. We retrospectively evaluated 120 patients who underwent abdominoperineal resection at the Changhai Hospital between February 2018 and October 2021 and divided them into two groups according to their treatment: the INPWT group (n = 60) and the control group (n = 60). The quality of post-surgical wound healing in the two groups was evaluated. The Patient Scar Assessment Scale (PSAS), the Vancouver Scar Scale (VSS), and the visual analogue scale (VAS) were used to evaluate the surgical incision scar at 1-year follow-up. At this follow-up visit, 115 patients underwent reexamination; five patients were lost to follow-up, including two patients in the INPWT group and three patients in the control group. The INPWT group showed better wound healing than the control group (P < .05). The proportion of patients who received INPWT was significantly higher in the non-surgical site infection (SSI) group than in the SSI group (P < .05). The PSAS, VSS and VAS scores were significantly improved in the INPWT group compared with those in the control group (P < .05). Our results show that INPWT improved the quality of cosmetic suture wounds and reduced the degree of postoperative scar hyperplasia.

Omentoplasty in Patients Undergoing Abdominoperineal Resection After Long-Course Chemoradiation for Locally Advanced and Locally Recurrent Rectal Cancer: A Comparative Single-Institution Cohort Study

BACKGROUND

Omentoplasty is a commonly performed procedure after abdominoperineal resection for rectal cancer, but its effectiveness to reduce pelviperineal complications is not firmly established.

OBJECTIVE

This study aimed to assess the impact of omentoplasty on postoperative outcomes after long-course (chemo) radiotherapy and abdominoperineal resection in patients with locally advanced and locally recurrent rectal cancer.

DESIGN

Retrospective cohort study.

SETTINGS

Single center.

PATIENTS

All patients with locally advanced and locally recurrent rectal cancer undergoing abdominoperineal resection after neoadjuvant (chemo)radiation in a tertiary referral center between 2008 and 2020 were retrospectively reviewed.

MAIN OUTCOME MEASURES

Multivariable logistic and linear regression analyses were performed to analyze the association between omentoplasty and pelviperineal complications, duration of nasogastric tube drainage, and length of hospital stay.

RESULTS

A total of 305 patients were analyzed, of whom 245 underwent omentoplasty (80%). Pelviperineal complications occurred in 151 patients (50%) overall, in 125 patients (51%) with omentoplasty, and in 26 patients (43%) without omentoplasty. Independent predictors of pelviperineal complications in multivariable analyses were smoking (OR 2.68; 95% CI, 1.46-4.94) and high BMI (OR 1.68; 95% CI, 1.00-2.83), but not omentoplasty (OR 1.36; 95% CI, 0.77-2.40). The mean duration of nasogastric tube drainage was longer after omentoplasty (6 vs 4 d) with a significant association in multivariable analysis (β coefficient 1.97; 95% CI, 0.35-3.59). Patients undergoing omentoplasty had a significantly longer hospital stay (14 vs 10 d), and omentoplasty remained associated with a prolonged hospital stay after adjusting for confounding (β coefficient 3.05; 95% CI, 0.05-5.74).

LIMITATIONS

Retrospective design.

CONCLUSION

Omentoplasty was not associated with a reduced risk of the occurrence of short-term pelviperineal complications after abdominoperineal resection in patients undergoing long-course (chemo)radiotherapy. Furthermore, in patients undergoing omentoplasty, prolonged duration of nasogastric tube drainage and hospital stay was observed. See Video Abstract at http://links.lww.com/DCR/C124 .

ANTECEDENTES:La omentoplastía es un procedimiento que se realiza comúnmente después de la resección abdominoperineal por cáncer de recto, pero su efectividad para reducir las complicaciones pelvicoperineales no está firmemente establecida.OBJETIVO:Evaluar el impacto de la omentoplastía en las complicaciones pelvicoperineales a corto plazo y los resultados postoperatorios después quimioradioterapia de curso largo y resección abdominoperineal en pacientes con cáncer de recto localmente avanzado y localmente recurrente.DISEÑO:Estudio de cohorte retrospectivo.ESCENARIO:Centro único.PACIENTES:Se revisaron retrospectivamente todos los pacientes con cáncer de recto localmente avanzado y localmente recurrente sometidos a resección abdominoperineal después de quimioradiación neoadyuvante en un centro de referencia de tercer nivel entre 2008 y 2020.PRINCIPALES MEDIDAS DE RESULTADO:Se realizaron análisis de regresión lineal y logística multivariable para examinar la asociación entre la omentoplastía y las complicaciones pelvicoperineales (p. ej., problemas de heridas perineales y abscesos pélvicos), la duración del drenaje por sonda nasogástrica y la duración de la estancia hospitalaria.RESULTADOS:Se analizaron un total de 305 pacientes de los cuales 245 fueron sometidos a omentoplastía (80%). Las complicaciones pelvicoperineales ocurrieron en 151 pacientes (50%) en general, y en 125 (51%) y 26 (43%) de los pacientes con o sin omentoplastía, respectivamente. Los predictores independientes de complicaciones pelvicoperineales en análisis multivariable fueron el tabaquismo (OR 2.68, IC del 95% 1.46 a 4.94) y un IMC alto (OR 1.68, IC del 95% 1.00 a 2.83), pero no la omentoplastía (OR 1.36, IC del 95% 0.77 a 2.40) . La duración media del drenaje por sonda nasogástrica fue mayor después de la omentoplastía (6 frente a 4 días) con una asociación significativa en el análisis multivariable (coeficiente β 1.97, IC del 95%: 0.35-3.59). Los pacientes que se sometieron a una omentoplastía tuvieron una estancia hospitalaria significativamente más larga (14 frente a 10 días), y la omentoplastía permaneció asociada con una estancia hospitalaria prolongada después de ajustar por factores de confusión (coeficiente β 3.05, IC del 95%: 0.05-5.74).LIMITACIONES:Diseño retrospectivo.CONCLUSIÓN:La omentoplastía no se asoció con un riesgo reducido de aparición de complicaciones pelvicoperineales a corto plazo después de la resección abdominoperineal en pacientes sometidos a quimioradioterapia de larga duración. Adicionalmente, en los pacientes sometidos a omentoplastía se observó una duración prolongada del drenaje por sonda nasogástrica y la estancia hospitalaria.

Closed Incisional Negative Pressure Therapy Reduces Perineal Wound Complications After Abdominoperineal Resection

BACKGROUND

Perineal wound complications after abdominoperineal resection continue to be a significant challenge. Complications, ranging from 14% up to 60%, prolong hospitalization, increase risk of readmission and reoperation, delay the start of adjuvant therapy, and place psychological stress on the patient and family.

OBJECTIVE

This study aimed to evaluate the impact of closed incision negative pressure therapy on perineal wound healing.

DESIGN

This was a retrospective study.

SETTINGS

The study was conducted in an academic community hospital.

PATIENTS

Patients who underwent abdominoperineal resection from 2012 to 2020 were included.

MAIN OUTCOME MEASURES

Perineal wound complications within 30 and 180 days were the primary outcome measures.

RESULTS

A total of 45 patients were included in the study. Of these, 31 patients were managed with closed incision negative pressure therapy. The overall perineal wound complications were less frequent in the closed incision negative pressure therapy group (10/31; 32.2%) compared to the control group (10/14; 71.4%; = 5.99 [ p = 0.01]). In the closed incision negative pressure therapy group, 2 patients (20%) did not heal within 180 days and no patient required reoperation or readmission. In the control group, 4 patients (44%) had not healed at 180 days and 1 patient required flap reconstruction. When the effect of other variables was controlled, closed incision negative pressure therapy resulted in an 85% decrease in the odds of wound complications (adjusted OR 0.15 [95% CI, 0.03-0.60]; p = 0.01).

LIMITATIONS

The nonrandomized nature and use of historical controls in this study are its limitations.

CONCLUSIONS

The ease of application and the overall reduction in the incidence and severity of complications may offer an option for perineal wound management and possibly obviate the need for more expensive therapies. Further prospective controlled trials are required to effectively study its efficacy. See Video Abstract at http://links.lww.com/DCR/B895 .

Reconstruction with omental flap and negative pressure wound therapy after total pelvic exenteration of anal fistula cancer: a case report

Introduction

Surgery for anal fistula cancer (AFC) associated with Crohn’s disease usually entails extensive perineal wounds and dead space in the pelvis, which is often filled with a myocutaneous flap. However, use of a myocutaneous flap is invasive. We report a case of total pelvic exenteration (TPE) for AFC in which a myocutaneous flap was avoided by using an omental flap and negative pressure wound therapy (NPWT).

Case presentation

The patient was a 47-year-old woman who had been treated for Crohn’s disease involving the small and large intestine for 30 years and had repeatedly developed anal fistulas. She was referred with a diagnosis of AFC that had spread extensively in the pelvis. We performed laparoscopic TPE via a transperineal endoscopic approach. To prevent infection in the large skin defect and extensive pelvic dead space postoperatively, the perineal wound was reconstructed using an omental flap and NPWT. During 20 days of NPWT, the wound steadily decreased in size and closed on postoperative day (POD) 20. She was discharged without complications on POD 30.

Discussion

NPWT is useful for preventing perineal wound infection and promoting granulation tissue formation. However, direct contact with the intestine may lead to intestinal perforation. In this case, the combination of an omental flap with NPWT effectively prevented surgical site infection. The flap filled the large pelvic dead space and physically separated the intestine from the polyurethane foam used for NPWT.

Conclusion

NPWT and an omental flap may become an option when performing TPE.

Surgical Implications of LGBTQ+ Health Disparities: A Review

Lesbian, gay, bisexual, transgender, and queer/questioning (LGBTQ+) patients face challenging health care disparities. However, due to restrictions in reporting and collection of sexual orientation and gender identity (SOGI) demographic data, comprehensive studies of surgical disparities in the LGBTQ+ population are limited. This review aims to summarize the existing literature describing surgical disparities in LGBTQ+ patients and to identify areas of surgical care in which further studies are warranted. This review addresses the literature in infectious diseases, substance use disorders, bariatrics, cardiovascular medicine, oncology, and laryngology as relevant to surgical practice. Understanding the current landscape of knowledge in LGBTQ+ surgical disparities and the areas where gaps in research exist will help the surgeon to create a framework of practice to provide more equitable care to LGBTQ+ patients.

Continuous Negative Pressure Drainage with Intermittent Irrigation Leaded to a Risk Reduction of Perineal Surgical Site Infection Following Laparoscopic Extralevator Abdominoperineal Excision for Low Rectal Cancer

Purpose

High rate of perineal surgical site infection (SSI) is the most common complication following abdominoperineal resection (APR), especially for extralevator abdominoperineal excision (ELAPE). The purpose of this study was to investigate the effect of continuous negative pressure drainage combined with intermittent irrigation (CNPDCII) in the presacral space on the perineal SSI following laparoscopic ELAPE for low rectal cancer.

Patients and Methods

The clinical data of 99 patients with low rectal cancer who underwent laparoscopic ELAPE surgery were retrospectively analyzed. Among the 99 patients, 46 patients received CNPDCII and 53 patients received conventional drainage in the presacral space after ELAPE. Self-made irrigation drainage tube: took a silicone drainage tube, cut 3 side holes at every 2cm intervals at the front end, and fixed a flexible tube of an intravenous needle at the front end of the silicone drainage tube. The conventional drainage tube or self-made irrigation drainage tube was placed in the presacral space and poked out from the inside of the ischial tuberosity. The incidence of SSI and other perioperative indicators between the two groups was compared within 30 days after surgery.

Results

There was no statistical difference in clinicopathological features between the two groups of patients (p>0.05). A statistically lower rate of SSI was found in CNPDCII group (17.4%, 8/46) than the conventional drainage group (35.8%, 19/53). The drainage tube retention time (7.8±1.2 d VS 9.4±1.6 d) and the postoperative hospital stay (9.7±1.4 d VS 11.9±2.3 d) in CNPDCII group were significantly shortened than the conventional drainage group. There was no statistical difference in operating theatre time and intraoperative blood loss between the two groups. Multivariate analysis confirmed that CNPDCII was an independent protective factor for SSI after ELAPE.

Conclusion

CNPDCII can effectively reduce the incidence of SSI following laparoscopic ELAPE, which is simple, safe and effective.

Incisional negative pressure wound therapy to reduce perineal wound infection after abdominoperineal resection

We explored the effects of incisional negative pressure wound therapy in perineal wound infections after abdominoperineal resection. We retrospectively evaluated 146 patients who underwent abdominal perineal resection from December 2004 to December 2019 and compared conventional gauze dressing (controls) with incisional negative pressure wound therapy. We compared patients' characteristics, surgical factors, and perineal infection rates between groups, and patients' characteristics, surgical factors, and negative pressure therapy use between perineal infection vs non-infection groups, as well as the risk factors for perineal infections. In the negative pressure therapy group, compared with controls, the number of men, smoking prevalence, blood transfusion, drainage via the perineal wound, and intraoperative blood loss were significantly lower (p < 0.05, p < 0.05, p < 0.05, p < 0.001, p < 0.01, respectively), and operation time was significantly longer (p < 0.05). Infections were significantly less common in the negative pressure group (p < 0.05). In the univariate analysis, the infection-positive group had significantly higher laparoscopic surgery (p < 0.01) and negative pressure wound therapy-free rates (p < 0.01), and significantly more intraoperative blood loss (p < 0.05). Multivariate analysis using these three factors and preoperative radiotherapy showed that incisional negative pressure wound therapy-free status was a risk factor for infection. Incisional negative pressure wound therapy was beneficial in managing perineal wound infections after abdominoperineal resection.
