Study of negative pressure wound therapy in management of abdominal wound dehiscence

Background: Postlaparotomy Abdominal wound dehiscence (AWD) occurs in 0.25% to3%. Many technique are being used to manage AWD like surgical revision with open dressing/closed irrigation, temporary covering with ‘Bagota bag’, saline soak gause dressing, absorbable/permanent mesh. Negative-pressure wound therapy (NPWT) is a recent modality of treatment of wound. It involves controlled application of sub atmospheric pressure to local wound environment, using sealed wound dressing connected to vacuum pump. This study aimed at finding the effectiveness of negative pressure wound therapy in management of abdominal wound dehiscence over conventional methods of wound management.Methods: This was hospital based non randomised comparative prospective interventional study carried between July 2017 to November 2019, includes all patients admitted in GMCH, Nagpur Hospital having post laparotomy AWD, excluding the patients having enter ocutaneous fistula and patient not giving consent for VAC application. Total n=60 cases were included in study. Out of 60, 30 were taken as cases in whom intervention was done by applying vaccum assisted closure (VAC) therapy and 30 were control.Results: All 60 patients had undergone laparotomy of this patients 30 patients was applied NPWT and efficacy plotted on the parameter of, wound sepsis, wound contraction, length of hospital stay and extension of time therapy. It was found that 90% patients had negative c/s post VAC dressing, compared to 26% in post ns dressing, there was MWC of 0.86 cm in post VAC patients compared to 0.14 cm in post NS dressing, MHS was 18.9 days in cases and was 28 days in controls,13 patients had complete fascial closure in cases whereas none in controls.Conclusions: NPWT significantly reduces the hospital stay of patients, it causes faster and higher degree of wound contraction, reduces wound sepsis thereby reducing morbidity of patients.

Vacuum sealing drainage with anterolateral thigh perforator flap for repair foot soft tissue defect / 中国骨伤

<p><b>OBJECTIVE</b>To investigate clinical effect of vacuum sealing drainage(VSD) with anterolateral thigh perforator flap for repair foot soft tissue defect.</p><p><b>METHODS</b>From September 2014 to September 2016, 45 patients with foot soft tissue defect repaired by VSD with anterolateral thigh perforator flap, including 31 males and 14 females aged from 17 to 55 years with an average of 36 years old. Thirty patients were dorsal soft tissue defects, and 15 patients were plantar soft tissue defects. Sizes of soft tissue defect ranged from 7 cm×10 cm to 11 cm×18 cm, the wound was contaminated seriously and assisted with deep soft tissue exposure. Emergency surgical wound debridement with VSD treatment were performed, and wound surface was cleaned after 5 to 7 days, free anterolateral thigh flap were repaired. Sizes of flap ranged from 9 cm×12 cm to 13 cm×21 cm. Appropriate method was used to repair flap donor area.</p><p><b>RESULTS</b>All 45 free propeller flap were survived without skin edge necrosis, ulcerative infection. Forty patients were followed up from 3 to 24 months with an average of 13 months. Flap showed good color, beautiful appearance, good elasticity, soft texture, but without obvious bloated, the wood of leg healed well.</p><p><b>CONCLUSIONS</b>VSD with anterolateral thigh perforator flap for repair foot soft tissue defect could effective control wound soft tissue infection, receive reliable flap blood supply and skin flap could repaired at stage I. It is an effective method for repairing foot soft tissue defects.</p>

Fístula enteroatmosférica y uso del VAC: a propósito de un caso / Enteroatmospheric fistula and vaccum assited closure: report of a case

Las fístulas gastrointestinales asociadas con abdomen abierto posterior a cirugía abdominal mayor son una complicación grave. El manejo es extremadamente difícil y la mortalidad bastante alta a pesar de los modernos avances médicos. Aquellos pacientes que sobreviven al daño metabólico y fisiopatológico inicial, requieren en su mayoría cierre quirúrgico de la fístula lo cual es técnicamente complejo. Presentamos el caso de un paciente con una neoplasia de rectosigma que se abordó por laparoscopia y desarrolló una fístula enteroatmosférica sobre la incisión de Pfannestiel que se utilizó para la extracción de la pieza. Conclusión: El cierre asistido por vacío artesanal y el manejo nutricional adecuado permiten la mejoría en pacientes con fístulas complejas logrando las condiciones adecuadas para el cierre definitivo.

The gastrointestinal fistula associated to posterior open abdominal trauma or abdominal surgery implies severe complications. The handling of these cases is extremely hard and mortality is very high despite medical advances. Those patients who survive the initial metabolic and phisycopathological damages require, on most cases, a surgical closure of the fistula which is a very complex procedure technically. We describe the case of a patient with a rectosigmoid neoplasm that was addressed laparoscopically and enteroatmospheric fistula just developing on phannestiel incision was used to extract the neoplasm. Conclusion: The closure assisted by “hand made vacuum” and adequate nourishment allows recovering patients with complex fistulas to achieve adequate conditions for definitive closure.

Vacuum-assisted Closure in Orthopedics / 中华医院感染学杂志

OBJECTIVE To observe the effect of vacuum-assisted closure in clinical persistent infection patients.METHODS Thirty two sufferers infected in soft tissue,bones and joints were treated by general methods but without durable concrescence.It lasted averagely 138 days.In our department it treated by vacuum-assisted closure in 23 days.Thereby a comparison of self-control came into being.RESULTS Thirty two cases were cured after following at least one year except for one case with recrudescence.CONCLUSIONS Vaccum-assisted closure is the most effective surgery therapy measurement and is a kind of unidirectional drainage.If we can use it felicitously then we can treat infection in orthopedics′ effectively.
