Purse-string skin closure versus linear skin closure techniques in stoma closure: a comprehensive meta-analysis with trial sequential analysis of randomised trials

Diverting ileostomy in benign colorectal surgery: the real clinical cost analysis

There are three types of complications stoma related: ones related to its construction, ones related to its function and related to closure. The aim of this study was to assess the risk of complications related to the stoma presence and to identificate variables related to complications. We conducted a retrospective study of patients who underwent sphincter-preserving elective surgery for benign condition between January 2013 and December 2020 at IRCCS Sacro Cuore Don Calabria Hospital in Negrar, Verona. Data were collected regarding demographics and complications associated with primary surgery, stoma closure and the interval period. Univariable and multivariable analysIs were conducted. A total of 446 (12.2%) diverting loop ileostomies were performed. At index procedure, 76 (17%) patients had complications and 34 patients had complications related to ileostomy creation. Twenty patients (4.4%) were re admitted before stoma closure for dehydration. One hundred and eighty-seven patients (41.9%) suffered from ileostomy management's problems. At univariate analysis, complications of having stoma are more frequent in elder patients (p = 0.013), ASA score > 2 (p = 0.02), IBD diagnosis (p = < 0.001) and patients who had ileostomy creation complications (p = 0.04). At stoma closure, 55 (12.3%) patients had complications. Forty-seven patients (10.5%) presented incisional hernia in the stoma closure site. Ileostomy closure complications are more common with ASA score > 2 (p = 0.01) and IBD diagnosis (p < 0.001). IBD was found an independent factor of poor outcome at the time of ileostomy creation and closure. Developing complications at the time of ileostomy creation is statistically related to develop complications during ileostomy maintenance at multivariable analysis A loop ileostomy is usually created to limit the potentially life-threatening consequenceS of anastomotic leakage, but it is not able to decrease the leak-related mortality, wound sepsis, postoperative bleeding and small bowel obstruction. Debate rises not only for its uncertain efficacy but also because of the significant morbidity related to stoma. The surgeon could use these data in order to tailor his surgical strategy to the patients and their disease.

Clinical Benefits of Reducing Dead Space Using a Closed Suction Drain and Subcutaneous Large-bite Buried Suture Technique to Prevent Superficial Surgical-site Infections Following Primary Closure of a Diverting Stoma

Objectives

Surgical-site infections (SSIs) are the most common complication after stoma closure. We propose a new method for wound closure using the subcutaneous large-bite buried suture (SLBS) technique and a closed suction drain (CSD). In this study, we aimed to investigate the efficacy of a combination of the SLBS technique and a CSD to prevent superficial SSIs following stoma closure.

Methods

We retrospectively analyzed patients who underwent stoma closure between January 2019 and July 2022. Primary closure of the stomal site was performed using the SLBS technique and a CSD for wound closure. The CSD was placed until postoperative day 7. The occurrence of superficial postoperative SSIs was also evaluated.

Results

In total, 67 patients were included in the study. Within 30 days postoperatively, nine patients (13%) developed superficial SSIs. Considering the type of stoma, only 1 (2%) of 45 patients with ileostomy showed superficial SSIs, whereas 8 (36%) of 22 patients with colostomy showed superficial SSIs. Univariate analysis of the risk factors associated with the occurrence of superficial SSIs revealed that colostomy (p < 0.001) and hand-sewn anastomosis were significant risk factors (p = 0.019). Multivariate analysis of the risk factors associated with the occurrence of superficial SSIs revealed that colostomy was significant risk factor (p = 0.003).

Conclusions

This new method of stoma closure is feasible for preventing superficial SSIs, especially in ileostomy closure.

Purse-string skin closure versus linear skin closure in people undergoing stoma reversal

BACKGROUND

Stoma reversal is associated with a relatively high risk of surgical site infection (SSI), occurring in up to 40% of cases. This may be explained by the presence of microorganisms around the stoma site, and possible contamination with the intestinal contents during the open-end manipulation of the bowel, making the stoma closure site a clean-contaminated wound. The conventional technique for stoma reversal is linear skin closure (LSC). The purse-string skin closure (PSSC) technique (circumferential skin approximation) creates a small opening in the centre of the wound, enabling free drainage of contaminants and serous fluid. This could decrease the risk of SSI compared with LSC.

OBJECTIVES

To assess the effects of purse-string skin closure compared with linear skin closure in people undergoing stoma reversal.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, two other databases, and three trials registers on 21 December 2022. We also checked references, searched for citations, and contacted study authors to identify additional studies.

SELECTION CRITERIA

We included all randomised controlled trials (RCTs) comparing PSSC and LSC techniques in people undergoing closure of stoma (loop ileostomy, end ileostomy, loop colostomy, or end colostomy) created for any indication.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected eligible studies, extracted data, evaluated the methodological quality of the included studies, and conducted the analyses. The most clinically relevant outcomes were SSI, participant satisfaction, incisional hernia, and operative time. We calculated odds ratios (ORs) for dichotomous data and mean differences (MDs) for continuous data, each with its corresponding 95% confidence interval (CI). We used the GRADE approach to rate the certainty of the evidence.

MAIN RESULTS

Nine RCTs involving 757 participants were eligible for inclusion. Eight studies recruited only adults (aged 18 years and older), and one study included people aged 12 years and older. The participants underwent elective reversal of either ileostomy (82%) or colostomy (18%). We considered all studies at high risk of performance and detection bias (lack of blinding) and four studies at unclear risk of selection bias related to random sequence generation. PSSC compared with LSC likely reduces the risk of SSI (OR 0.17, 95% CI 0.09 to 0.29; I2 = 0%; 9 studies, 757 participants; moderate-certainty evidence). The anticipated absolute risk of SSI is 52 per 1000 people who have PSSC and 243 per 1000 people who have LSC. The likelihood of being very satisfied or satisfied with stoma closure may be higher amongst people who have PSSC compared with people who have LSC (100% vs 89%; OR 20.11, 95% CI 1.09 to 369.88; 2 studies, 122 participants; low-certainty evidence). The results of the analysis suggest that PSSC compared with LSC may have little or no effect on the risk of incisional hernia (OR 0.51, 95% CI 0.07 to 3.70; I2 = 49%; 4 studies, 297 participants; very low-certainty evidence) and operative time (MD -2.67 minutes, 95% CI -8.56 to 3.22; I2 = 65%; 6 studies, 460 participants; very low-certainty evidence).

AUTHORS' CONCLUSIONS

PSSC compared with LSC likely reduces the risk of SSI in people undergoing reversal of stoma. People who have PSSC may be more satisfied with the result compared with people who have LSC. There may be little or no difference between the skin closure techniques in terms of incisional hernia and operative time, though the evidence for these two outcomes is very uncertain.

Early diverting stoma closure is feasible and safe: results from a before-and-after study on the implementation of an early closure protocol at a tertiary referral center

BACKGROUND

Evidence on early closure (EC) of defunctioning stoma (DS) after colorectal surgery shows a favorable effect when patients are carefully selected. Therefore, a clinical pathway adapted to the implementation of an EC strategy was developed in our center. The aim of this study was to carry out a comparative analysis of time until DS closure and DS-related morbidity before and after the implementation of an EC protocol (ECP).

METHODS

This study is a before-and-after comparative analysis. Patients were divided into two cohorts according to the observational period: patients from the period before the ECP implementation (January 2015-December 2019) [Period 1] and those from the period after that (January 2020-December 2022) [Period 2]. All consecutive patients subjected to elective DS closure within both periods were eligible. Early closure was defined as the reversal within 30 days from DS creation. Patients excluded from EC or those not closed within 30 days since primary surgery were analyzed as late closure (LC). Baseline characteristics and DS-related morbidity were recorded.

RESULTS

A total of 145 patients were analyzed. Median time with DS was shorter in patients after ECP implementation [42 (21-193) days versus 233 (137-382) days, p < 0.001]. This reduction in time to closure did not impact the DS closure morbidity and resulted in less DS morbidity (68.8% versus 49.2%, p = 0.017) and fewer stoma nurse visits (p = 0.029).

CONCLUSIONS

The ECP was able to significantly reduce intervals to restoration of bowel continuity in patients with DS, which in turn resulted in a direct impact on the reduction of DS morbidity without negatively affecting DS closure morbidity.

A case series of prophylactic negative pressure wound therapy use with purse-string closure in stoma closure wounds in infants

BACKGROUND

The study introduces the application of negative pressure wound therapy (NPWT) in pediatric stoma closure, emphasizing the importance of enhancing aesthetics and minimizing surgical site infections (SSI).

CASE PRESENTATION

The case series involves four infants undergoing non-umbilical stoma closure with a combination of purse-string closure (PSC) and NPWT, focusing on aesthetic outcomes and infection prevention. NPWT was initiated immediately after surgery, and patients were monitored every 3-4 days. Notably, none of the four infants experienced SSI or other complications. The patients adequately tolerated NPWT, with no significant adverse events. Furthermore, Manchester Scar Scale (MSS) was 9 [7-10], and Patient and Observer Scar Assessment Scale (POSAS) (observer) was 12.5 [12-19], POSAS (patient) was 12.5 [11-16] (all median values [minimum-maximum]), indicating that excellent aesthetic outcomes were achieved.

DISCUSSION

We emphasizes the significance of aesthetics in pediatric patients; in addition, our findings demonstrate that four infants who received NPWT combined with PSC achieved superior outcomes that did the most recent four infants who underwent PSC only at our institution. It also addresses the risk of SSI in stoma closure and discusses the pros and potential cons of using NPWT in pediatric cases, underlining the need for further research and the accumulation of additional reports.

CONCLUSIONS

This is the inaugural report of prophylactic NPWT for pediatric stoma closure, emphasizing the effectiveness of combining PSC and NPWT for SSI prevention and improved aesthetics. The study calls for additional research and reports on NPWT in pediatric cases to further solidify its benefits in this patient population.

The effectiveness of negative-pressure wound therapy for wound healing after stoma reversal: a randomized control study

Purpose

The purse-string closure (PSC) method is used for skin closure after stoma reversal to reduce surgical site infections (SSIs). However, PSC requires a longer healing period than primary closure. The application of negative-pressure wound therapy (NPWT) may reduce the healing period of many wound types. This study aimed to investigate whether the application of NPWT promotes wound healing after the PSC method for stoma reversal.

Methods

This study was a randomized controlled study. Patients who had undergone stoma reversal surgery were randomized to receive NPWT or simple dressing after surgery. The primary outcome was a complete wound-healing period. We also investigated SSI, hospital stay, total cost, and the patient and observer scar assessment scale (POSAS) as secondary outcomes.

Results

A total of 36 patients were randomized into 2 groups. The median wound healing period was shorter in the NPWT group than in the control group (17.5 days [range, 11-24 days] vs. 21.5 days [range, 14-41 days], P = 0.006). SSI rate and hospital stay did not differ between the groups. However, the number of dressings was lower in the NPWT group than in the control group (5 [range, 3-7] vs. 17 [range, 10-30], P < 0.001). The total cost for dressing was comparable between the groups. The POSAS was not different between the groups.

Conclusion

This study revealed that NPWT application after PSC for stoma reversal site is effective in reducing the wound healing period compared to simple dressing, without increasing SSI and total cost.

Comparison of modified gunsight suture technique and traditional interrupted suture in enterostomy closure

BACKGROUND

Prophylactic enterostomy surgery is a common surgical approach used to reduce the risk of anastomotic leakage in patients who have undergone partial intestinal resection due to trauma or tumors. However, the traditional interrupted suturing technique used in enterostomy closure surgery has several issues, including longer surgical incisions and higher incision tension, which can increase the risk of postoperative complications. To address these issues, scholars have proposed the use of a "gunsight suture" technique. This technique involves using a gunsight incision instead of a traditional linear incision, leaving a gap in the center for the drainage of blood and fluid to reduce the risk of infection. Building on this technique, we propose an improved gunsight suture technique. A drainage tube is placed at the lowest point of the incision and close the gap in the center of the gunsight suture, which theoretically facilitates early postoperative mobility and reduces the burden of dressing changes, thereby reducing the risk of postoperative complications.

AIM

To compare the effectiveness of improved gunsight suture technique with traditional interrupted suture in closing intestinal stomas.

METHODS

In this study, a retrospective, single-center case analysis was conducted on 270 patients who underwent prophylactic ileostomy closure surgery at the Department of Colorectal Surgery of Qilu Hospital from April 2017 to December 2021. The patients were divided into two groups: 135 patients received sutures using the improved gunsight method, while the remaining 135 patients were sutured with the traditional interrupted suture method. We collected data on a variety of parameters, such as operation time, postoperative pain score, body temperature, length of hospital stays, laboratory indicators, incidence of incisional complications, number of wound dressing changes, and hospitalization costs. Non-parametric tests and chi-square tests were utilized for data analysis.

RESULTS

There were no statistically significant differences in general patient information between the two groups, including the interval between the first surgery and the stoma closure [132 (105, 184) d vs 134 (109, 181) d, P = 0.63], gender ratio (0.64 vs 0.69, P = 0.44), age [62 (52, 68) years vs 60 (52, 68) years, P = 0.33], preoperative body mass index (BMI) [23.83 (21.60, 25.95) kg/m² vs 23.12 (20.94, 25.06) kg/m², P = 0.17]. The incidence of incision infection in the improved gunsight suture group tended to be lower than that in the traditional interrupted suture group [ (n = 2/135, 1.4%) vs (n = 10/135, 7.4%), P < 0.05], and the postoperative hospital stay in the improved gunsight suture group was significantly shorter than that in the traditional interrupted suture group [5 (4, 7) d vs 7 (6, 8) d, P < 0.05]. Additionally, the surgical cost in the modified gunsight suture group was slightly lower than that in the traditional suture group [4840 (4330, 5138) yuan vs 4980 (4726, 5221) yuan, P > 0.05], but there was no significant difference in the total hospitalization cost between the two groups.

CONCLUSION

In stoma closure surgery, the improved gunsight technique can reduce the incision infection rate, shorten the postoperative hospital stay, reduce wound tension, and provide better wound cosmetic effects compared to traditional interrupted suture.

COMPARISON BETWEEN OSTOMY CLOSURE USING PURSE-STRING VERSUS LINEAR IN CHILDREN

BACKGROUND

Type of ostomy closure has connection with some complications and also cosmetic effects.

AIMS

This study aimed to compare result of colostomy closure using purse-string method versus linear method in terms of surgical site infection, surgical time, and patient satisfaction.

METHODS

In this study, 50 patients who underwent purse-string ostomy closure and 50 patients who underwent linear closure were included. Two groups were compared for surgical time, wound infection, patient satisfaction, scar length. A p-value <0.05 was considered significant.

RESULTS

Wound infection was not reported among purse-string group compared to 10% in linear group (p=0.022). Scar length was 24.09±0.1 mm in purse string and 52.15±1.0 mm in linear group (p=0.033). Duration of hospital admission was significantly shorter in purse-string group (6.4±1.1 days) compared to linear (15.5±4.6 days, p=0.0001). The Patient and Observer Scar Assessment Scale scale for observer (p=0.038) and parents (p=0.045) was more favorable among purse-string group compared to linear.

CONCLUSION

Purse-string technique has the less frequent surgical site infection, shorter duration of hospital admission, less scar length, and more favorable cosmetic outcome, compared to linear technique.

Natural history of anastomotic leakage after elective stoma closure

INTRODUCTION

Elective stoma closure (ESC) is a common procedure. The main complication of ESC is anastomotic leakage, which can be revealed by peritonitis or an enterocutaneous fistula (ECF). The objective of the present study was to describe the natural history of AL after ESC.

PATIENTS AND METHODS

Between January 2015 and March 2020, all patients having undergone AL after loop or double-barreled ESC were included in a retrospective, single-center study. The rate of ECF and peritonitis at presentation, the success rate of a conservative treatment and the factors associated with the success of healing of ECF were evaluated.

RESULTS

From January 2015 to March 2020, 619 patients underwent a loop or double-barreled ESC in our department. The AL rate was 6.3% (n=39). The leakage was revealed by an ECF in 72% of cases (n=28). The mean±standard deviation time between the stoma closure and the diagnosis of the AL was 6±4 days. Conservative treatment was successful in 24 (85%) of the 28 patients with ECF, with a mean±SD time to recovery of 6.6±9.4 months. In a univariate analysis, none of the conservative treatments was significantly associated with healing of the ECF.

CONCLUSION

AL is not rare and is mainly revealed by an ECF. Although the fistula heals in most cases, both the surgeon and the patient must be aware that the time to recovery is long.

Closed-wound negative pressure therapy dressing after loop ostomy closure: a retrospective comparative study

Closed-wound negative pressure wound therapy (NPWT) dressings were recently introduced with the purpose to reduce incisional surgical site infections (iSSI) in high-risk wounds. The aim of this study was to compare iSSI rates in patients after ostomy closure with and without additional application of a closed-wound NPWT dressing. Single-center retrospective analysis of consecutive patients undergoing ileo- or colostomy closure over an 8-year period (January 2013-January 2021). Intradermal non-purse string technique with absorbable sutures were used in all patients. Since November 2018, all patients (study group) received a NPWT device for a maximum of 5 days postoperatively (PICO, SMITH AND NEPHEW). Primary outcome was iSSI rate within 30 days of surgery. SSI was defined in accordance with the Center of Disease Control (CDC) classification and included superficial and deep incisional SSI. Data was retrieved from the institutional enhanced recovery after surgery (ERAS) database, with standardized complication assessment by trained abstractors. In total, 85 patients (25%) in the study group were comparable with 252 (75%) patients in the control group regarding demographics (age, gender, body mass index, ASA score), ostomy type and anastomotic technique (all p > 0.05), but not wound contamination class (class III: 5% vs 0%, p < 0.001). Median time to NPWT removal was 4 (IQR 3-5) days. Incisional SSI were observed in 4 patients (4.7%) in the study group and in 27 patients (10.7%) in the control group (p = 0.097). These preliminary results suggest a potential benefit of systematic application of the NPWT device after loop ostomy closure. A randomized controlled study is needed.

Intervenciones de Enfermería en la reversión del estoma intestinal: revisión integrativa

Introducción: los estomas intestinales representan un impacto significativo en la calidad de vida de las personas; sin embargo, estos deben revertirse después de haberse restituido el tránsito intestinal o la resolución del proceso inflamatorio inicial. Por otro lado, la negación de la persona para su reversión puede deberse a la falta de información y orientación por parte de los profesionales de la salud. Por lo anterior es importante identificar las intervenciones de Enfermería en la atención de la persona con reversión del estoma intestinal. Materiales y métodos: se realizó una revisión integrativa de la literatura de alcance descriptivo en el período comprendido entre los años 2015 a 2020, a través de las bases de datos Wos, Pubmed, Scopus, Scielo y Cochrane. Se seleccionaron 36 artículos que cumplieron con los criterios de inclusión y exclusión con el respectivo análisis metodológico. Resultados: Se identificaron las siguientes intervenciones de Enfermería, para el preoperatorio: valoración preoperatoria, preparación intestinal y seguimiento a comorbilidades. El intraoperatorio: profilaxis, preparación de la piel, técnica quirúrgica y cierre de la pared abdominal. En el posoperatorio: cuidado de la herida quirúrgica, calidad de vida y educación. Discusión: es importante la reflexión sobre el tiempo de reversión, la técnica quirúrgica y la importancia de las intervenciones por Enfermería. Conclusión: Enfermería cumple un papel importante en la reversión del estoma, no solo por los cuidados físicos y la educación que se brinda, sino también en las intervenciones aplicables al contexto social y emocional que afectan el estilo de vida de la persona.

Negative-pressure wound therapy after stoma reversal in colorectal surgery: a randomized controlled trial

Background

Stoma-reversal surgery is associated with high postoperative morbidity, including wound complications and surgical-site infections (SSIs). This study aims to assess whether the application of negative-pressure wound therapy (NPWT) can improve wound healing compared with conventional wound dressing.

Methods

This was a single-centre, superiority, open-label, parallel, individually randomized controlled trial. Patients undergoing stoma reversal were randomized (1 : 1) to receive NPWT or conventional wound dressing. The primary endpoint of the study was the rate of wound complications and SSIs after stoma closure. The secondary endpoints were postoperative wound pain, rate of wound healing after 30 days from stoma closure, and wound aesthetic satisfaction.

Results

Between June 2019 and January 2021, 50 patients were allocated to the NPWT group (all received NPWT, 49 were analysed); 50 patients were allocated to the conventional wound dressing group (48 received the treatment, 45 were analysed). No significant difference was found in wound-complication rate (10 per cent NPWT versus 16 per cent controls; odds ratio 0.61 (95 per cent c.i. 0.18 to 2.10), P = 0.542) and incisional SSI rate (8 per cent NPWT versus 7 per cent controls; odds ratio 1.24 (95 per cent c.i. 0.26 to 5.99), P = 1.000). The NPWT group showed less pain, higher aesthetic satisfaction (P < 0.0001), and a higher proportion of wound healing (92 versus 78 per cent; P = 0.081) compared with the control group.

Conclusion

NPWT does not reduce the incidence of SSI after stoma-reversal surgery compared with conventional wound dressing. However, NPWT improved the healing of uninfected wounds, reduced wound pain and led to better aesthetic outcomes.

Registration number: NCT037812016 (clinicaltrials.gov).

Negative pressure therapy for stoma closure sites-a nonrandomised case control study

AIM

The PICO (Smith & Nephew, UK) dressing is a single use negative pressure wound therapy (NPWT) system that is designed to be used for up to 7 days for closed wounds. We aimed to assess its use for stoma closure wounds.

METHOD

We conducted a retrospective analysis of stoma reversal wounds from April 2018 to June 2019. The wound was partially closed with an absorbable subcutaneous suture in a purse-string fashion. A 15 cm × 15 cm PICO dressing was applied directly over this wound. A control group who had received partial purse string closure with packing over the same time period was identified. Patients were contacted and information collected using a questionnaire. The primary outcome measure was the number of visits for dressing changes in the community. Further information was collected about length of stay, time to resolution of pain and return to work.

RESULTS

On average, the patients with PICO dressings attended the community nurses 1.9 times. The patients in the PICO group stated it took 1-2 weeks to return to full work/daily activities. The control group averaged attending the community nurse 11.9 times, and 33% had not returned to work/daily activities in 1-2 weeks.

CONCLUSION

Those who had a PICO dressing required fewer visits to the community nurse and the majority were able to return to work or resume usual activities within 1 to 2 weeks. This pilot study suggests that negative pressure dressings may be a useful aid for stoma closure site wounds.

Gunsight Procedure Versus the Purse-String Procedure for Closing Wounds After Stoma Reversal: A Multicenter Prospective Randomized Trial

BACKGROUND

Stoma reversal is associated with a high risk of wound infection. The gunsight and purse-string closure techniques are both effective alternatives for stoma reversal, but comparative studies are lacking.

OBJECTIVE

The purpose of this study was to compare the gunsight procedure with the purse-string closure technique when closing wounds after loop stoma reversal.

DESIGN

This was a nonblinded, multicenter prospective randomized study (clinicaltrials.gov No. NCT02053948).

SETTINGS

The study was conducted at a general surgery unit of 7 tertiary academic medical centers.

PATIENTS

A total of 143 patients undergoing loop stoma reversal were included in the study (72 in the gunsight group and 71 in the purse-string group) between November 2013 and December 2017.

INTERVENTION

Patients were randomly assigned to undergo either gunsight or purse-string closure procedure.

MAIN OUTCOME MEASURES

Primary outcome was wound healing time. Secondary outcomes were the incidence of surgical site infection, morbidity, and patient satisfaction.

RESULTS

No differences were found between the 2 groups in terms of surgical site infection, intraoperative blood loss, and postoperative hospital stay. The gunsight procedure had a shorter wound healing time compared with the purse-string procedure (17 vs 25 d; p < 0.001). A patient satisfaction questionnaire showed that the gunsight group had a higher score level of patient satisfaction with respect to wound healing time (p < 0.001) and total patient satisfaction score (p = 0.01) than the purse-string group.

LIMITATIONS

Treatment teams were not blinded, and there was operator dependence of techniques.

CONCLUSIONS

The gunsight and purse-string techniques are effective procedures for stoma reversal and both have a low incidence of surgical site infection. The gunsight technique is associated with shorter wound healing time, higher levels of patient satisfaction with regard to healing time, and overall final score and is recommended as the closure technique of choice.

El procedimiento de gunsight tuvo un tiempo más corto en la cicatrización de la herida, en comparación con el procedimiento de jareta (17 días frente a 25 días, p <0,001). Un cuestionario de satisfacción del paciente, mostró que el grupo de gunsight tenía una puntuación más alta en relación al tiempo de cicatrización de la herida (p <0.001) y la puntuación total en satisfacción del paciente (p = 0.01), que en el grupo de jareta.Los equipos de tratamiento quirúrgico, no fueron cegados y hubo en los cirujanos, dependencia en las técnicas.Las técnicas de gunsight y de jareta son procedimientos efectivos para la reversión de estoma y ambas tienen una baja incidencia de infección en el sitio quirúrgico. La técnica de gunsight está asociada con un tiempo más corto en cicatrización de heridas, mejores niveles en satisfacción del tiempo de cicatrización y en la puntuación general final. Se recomienda como la técnica de cierre de elección. Consulte Video Resumen en http://links.lww.com/DCR/B319. (Traducción-Dr Fidel Ruiz Healy).

Meta-analysis and single-center experience on the protective effect of negative suction drains on wound healing after stoma reversal

BACKGROUND

Compromised wound healing following stoma reversal is a frequent problem. The use of negative suction drainage for reduction of complications remains controversial.

METHODS

The patient database of our center was reviewed for patients with ileostomy reversal between 2007 and 2017. Risk factors for wound complications were analyzed using multivariate regression analysis. Systematic review and meta-analysis was performed. Ultimately, results of this study were integrated into meta-analysis to assess the effect of drainage placement on wound healing.

RESULTS

In our institutional analysis, a total of 406 patients with ileostomy reversal were included (n = 240 (59.1%) with drainage vs. n = 166 (40.8%) without drainage). In multivariate analysis, body mass index (BMI) was a risk factor for wound complications (odds ratio (95% CI) 1.06 (1.02-1.12)). Patients with drainage needed significantly fewer interventions than those without drainage (17.1% vs. 28.9%, p = 0.005). Placement of drainage significantly reduced the risk of wound complications even in the group with elevated BMI (odds ratio (95% CI) 0.462 (0.28-0.76), p = 0.003). Meta-analysis identified 6 studies with a total of 1180 patients eligible for further analysis (2 prospectively randomized trials; 4 retrospective cohort studies). Overall analysis revealed a significantly beneficial effect of wound drainage following ileostomy reversal (RR (95% CI) 0.47 (0.34, 0.66); p < 0.0001).

CONCLUSION

In our institutional analysis as well as meta-analysis, the use of subcutaneous suction drains was beneficial for prevention of wound healing complications following ostomy reversal. Drainage placement is especially valuable in high-risk situations such as in obese patients.

Biological Treatment and the Potential Risk of Adverse Postoperative Outcome in Patients With Inflammatory Bowel Disease: An Open-Source Expert Panel Review of the Current Literature and Future Perspectives

Background

There is widespread concern that treatment with biologic agents may be associated with suboptimal postoperative outcome after surgery for inflammatory bowel diseases (IBD).

Aim

We aimed to search and analyze the literature regarding the potential association of biologic treatment on adverse postoperative outcome in patients with IBD. We used the subject as a case in point for surgical research. The aim was not to conduct a new systematic review.

Method

This is an updated narrative review written in a collaborative method by authors invited through Twitter via the following hashtags (#OpenSourceResearch and #SoMe4Surgery). The manuscript was presented as slides on Twitter to allow discussion of each section of the paper sequentially. A Google document was created, which was shared across social media, and comments and edits were verified by the primary author to ensure accuracy and consistency.

Results

Forty-one collaborators responded to the invitation, and a total of 106 studies were identified that investigated the potential association of preoperative biological treatment on postoperative outcome in patients with IBD. Most of these studies were retrospective observational cohorts: 3 were prospective, 4 experimental, and 3 population-based studies. These studies were previously analyzed in 10 systematic/narrative reviews and 14 meta-analyses. Type of biologic agents, dose, drug concentration, antidrug antibodies, interval between last dose, and types of surgery varied widely among the studies. Adjustment for confounders and bias control ranged from good to very poor. Only 10 studies reported postoperative outcome according to Clavien–Dindo classification.

Conclusion

Although a large number of studies investigated the potential effect of biological treatment on postoperative outcomes, many reported divergent results. There is a need for randomized controlled trials. Future studies should focus on the avoiding the weakness of prior studies we identified. Seeking collaborators and sharing information via Twitter was integral to widening the contributors/authors and peer review for this article and was an effective method of collaboration.

Incidence and risk factors for incisional hernia after temporary loop ileostomy closure: choosing candidates for prophylactic mesh placement

OBJECTIVES

The primary aim of this study was to identify the incisional hernia rate after temporary loop ileostomy closure. Secondary outcomes were determining the risk factors linked to this incisional hernia, which could improve the patient selection for mesh prophylaxis.

METHODS

Retrospective cohort study of all consecutive patients with temporary loop ileostomy reversal through a peristomal incision from 1st January 2011 to 1st January 2017 at our centre. Data were extracted from electronic clinical records: baseline patient characteristics, surgical factors and postoperative events. CT scans performed during follow-up were precisely analysed. Survival analysis was applied to identify risk factors for hernia development.

RESULTS

129 patients were analysed of whom 15 (11.6%) developed an incisional hernia at previous ileostomy site. The median time for incisional hernia development was 11 months (IQR = 7-21) and the median follow-up time was 37 months (IQR = 22-57). The identified patient risk factors for hernia development in survival analysis were female sex, older age, higher Body Mass Index, clinically significant parastomal hernia, clinically detectable midline incisional hernia and major postoperative complications ranked as Clavien-Dindo grade III and IV.

CONCLUSIONS

Incisional hernia after temporary loop ileostomy is a relevant problem that affects at least one in every ten patients. The previously cited risk factors might favour its development, therefore the use of a prophylactic mesh should be considered in those high-risk patients.

Meta-analysis of temporary loop ileostomy closure during or after adjuvant chemotherapy following rectal cancer resection: the dilemma remains

OBJECTIVE

To evaluate comparative outcomes of temporary loop ileostomy closure during or after adjuvant chemotherapy following rectal cancer resection.

METHODS

We systematic searched MEDLINE, EMBASE, CINAHL, CENTRAL, the World Health Organization International Clinical Trials Registry, ClinicalTrials.gov , ISRCTN Register and bibliographic reference lists. Overall perioperative complications, anastomotic leak, surgical site infection, ileus and length of hospital stay were the evaluated outcome parameters. Combined overall effect sizes were calculated using fixed effects or random effects models.

RESULTS

We identified 4 studies reporting a total of 436 patients comparing outcomes of temporary loop ileostomy closure during (n = 185) or after (n = 251) adjuvant chemotherapy following colorectal cancer resection. There was no significant difference in overall perioperative complications (OR 1.39; 95% CI 0.82-2.36, p = 0.22), anastomotic leak (OR 2.80; 95% CI 0.47-16.56, p = 0.26), surgical site infection (OR 1.97; 95% CI 0.80-4.90, p = 0.14), ileus (OR 1.22; 95% CI 0.50-2.96, p = 0.66) or length of hospital stay (MD 0.02; 95% CI - 0.85-0.89, p = 0.97) between two groups. Between-study heterogeneity was low in all analyses.

CONCLUSIONS

The meta-analysis of the best, albeit limited, available evidence suggests that temporary loop ileostomy closure during adjuvant chemotherapy following rectal cancer resection may be associated with comparable outcomes to the closure of ileostomy after adjuvant chemotherapy. We encourage future research to concentrate on the completeness of chemotherapy and quality of life which can determine the appropriateness of either approach.
