Practical use of transanal decompression tube following the repair of fourth-degree perineal tears associated with vaginal delivery

BACKGROUND

Fourth-degree perineal tears associated with vaginal delivery (PTAVD) occur in approximately 0.25 to 6% of vaginal deliveries. A persistent challenge in treating fourth-degree PTAVD is the high incidence of anastomotic leakage, leading to impaired quality of life, marked by incontinence, rectovaginal fistula, and painful sexual intercourse. Thus, effective interventions are necessary. Herein, we report our successful approach in repairing a fourth-degree PTAVD, involving the placement of a transanal decompression tube (TDT) during the early postoperative period.

CASE PRESENTATION

Five patients underwent the repair of fourth-degree PTAVD by suturing the mucosal and muscular layers of the rectum, and the vaginal wall in layers. Subsequently, a TDT was placed in the rectum, positioned 10-15 cm from the anal verge. The TDT was allowed to drain spontaneously without suction. Gastrografin enema examination was performed through a TDT, followed by a computed tomographic scan on postoperative days 3-4. After unfavorable complications were ruled out, the TDT was removed and the patients were transitioned to a normal diet.

RESULT

All patients showed favorable outcomes with no occurrence of vaginal fistula or incontinence.

CONCLUSION

This simple intervention demonstrates potential efficacy in reducing anastomotic leakage following the repair of fourth-degree PTAVD.

The Effect of Pelvic Floor Muscle Exercises on Bowel Evacuation and Quality of Life in Following Intestinal Ostomy Closure: Randomized Controlled Trial

PURPOSE

This purpose of this study was to evaluate the effect of pelvic floor muscle exercises (PFMEs) on bowel evacuation problems and health-related quality of life (HRQOL) following ostomy closure.

DESIGN

Randomized controlled trial.

SUBJECTS AND SETTING

Forty individuals following ostomy closure consented to participate in the study; 6 participants (15%) did not complete the trial (2 died and 2 required a second ostomy) yielding a study sample of 34. Participants were randomly allocated to an Exercise Group (EG, n = 17) and Control Group (CG, n = 17). The mean age of the EG was 55.7 (SD 12.6) years, whereas the mean age of the CG was 62.0 (SD 12.1) years. The study setting was the surgery clinic of 4 hospitals in Ankara, Turkey. Data were collected between December 2018 and May 2020.

METHODS

The study intervention, PFME training by a clinician, was administered to participants in the EG; CG participants received no information regarding PFME. Data were collected during face-to-face interviews on the day before discharge and by phone at the first, second, third, and sixth months after surgery. A questionnaire was used for data collection that queried a demographic and pertinent clinical questions, along with the Assessment Form for Bowel Evacuation Habits and Psychosocial Problems, Wexner Scale, and the Short Form (SF-36) Health-related Quality of Life Scale. Descriptive statistics and Mann-Whitney U test, t-test, Pearson-χ2 test, Fisher's Exact test, Friedman test, and Cochran-Q test statistical analysis according to normal distribution were used in data evaluation.

RESULTS

The number of defecations in the EG was statistically significantly lower than the CG at the second, third, and sixth months (P = .002, P = .002, P = .001, respectively). In addition, the number of individuals experiencing night defecation was statistically significantly less in the EG compared to the CG at the second-, third-, and sixth-month follow-ups (P = .001, P = .001, P = .028, respectively). HRQOL scores were also significantly higher in the EG.

CONCLUSION

Pelvic floor exercises applied after ostomy closure are effective in reducing bowel evacuation and increasing quality of life. Given these findings, PFMEs are recommended for patients after ostomy closure.

Comparing Surgical Site Infection Rate Between Primary Closure and Rhomboid Flap After Stoma Reversal

BACKGROUND

Primary closure (PC) is a common wound closure procedure after stoma reversal and is associated with a high rate of surgical site infection (SSI). This study introduced a new method of skin closure, a rhomboid flap (RF), for skin closure after stoma reversal and compared the SSI rate between the 2 techniques.

METHODS

This is a single-center retrospective study. Patients who underwent colostomy or ileostomy closure performed using either rotation flap (n = 33) or PC (n = 121) techniques for skin closure after stoma reversal between April 2019 and July 2022 were enrolled in this study. Medical records were retrospectively reviewed to obtain data. Both groups were followed up postoperatively at 1 month for wound infection. Wound infection within 30 days after surgery was indicated by the presence of purulent discharge, erythema, local heat, or positive culture for bacteria.

RESULTS

In the PC group, the infection rate was 25.6% (n = 121) compared with 12.1% (n = 33) in the RF group (P = 0.158). Among the patients who underwent colostomy reversal, the infection rate of the RF group was significantly lower compared with that of the PC group (11.1% vs 36.9%, P = 0.045). Among the patients who underwent ileostomy reversal, no significant differences in the infection rates between the groups were found (13.3% vs 12.5%, P = 1.000).

CONCLUSIONS

Although the RF technique requires slightly longer operative time for flap design in practice than the linear closure method, the technique can significantly reduce the SSI rate after colostomy reversal through the dissection of the surrounding inflammatory tissues and obliteration of the dead space. Additional studies are required to evaluate this technique, compare it with other existing methods, and explore long-term complications.

ILEOSTIM trial: a study protocol to evaluate the effectiveness of efferent loop stimulation before ileostomy reversal

PURPOSE

A protective loop ileostomy is the most useful method to reduce sequelae in the event of an anastomotic leakage (AL) after rectal cancer surgery. However, it requires an additional stoma reversal surgery with its own potential complications. Postoperative ileus (POI) remains the most common complication after ileostomy reversal, which leads to an increase in morbidity, length of hospital stay (LOS) and overall healthcare costs. Several retrospective studies carried out in this field have concluded that there are insufficient evidence-based recommendations about the routine application of preoperative bowel stimulation in clinical practice. Here we discuss whether stimulation of the efferent limb before ileostomy reversal might reduce POI and improve postoperative outcomes.

METHODS

This is a multicentre randomised controlled trial to determine whether mechanical stimulation of the efferent limb during the 2 weeks before the ileostomy reversal would help to reduce the development of POI after surgery. This study was registered on Clinicaltrials.gov (NCT05302557). Stimulation will consist of infusing a solution of 500 ml of saline chloride solution mixed with a thickening agent (Resource©, Nestlé Health Science; 6.4 g sachet) into the distal limb of the ileostomy loop. This will be performed within the 2 weeks before ileostomy reversal, in an outpatient clinic under the supervision of a trained stoma nurse.

CONCLUSION

The results of this study could provide some insights into the preoperative management of these patients.

Early-life gut dysbiosis has been associated with an increased risk of inflammatory, metabolic, and immune diseases later in life. Data on gut microbiota changes in infants undergoing intestinal surgery requiring enterostomy are scarce. This prospective cohort study examined the enterostomy effluent of 29 infants who underwent intestinal surgery due to congenital malformations of the gastrointestinal tract, necrotizing enterocolitis, or spontaneous intestinal perforation. Initial effluent samples were collected immediately after surgery and final effluent samples were collected three weeks later. Gut microbiota composition was analysed using real-time PCR and 16S rRNA gene sequencing. Three weeks after surgery, an increase in total bacteria number (+21%, p = 0.026), a decrease in Staphylococcus (-21%, p = 0.002) and Candida spp. (-16%, p = 0.045), and an increase in Lactobacillus (+3%, p = 0.045) and in less abundant genera belonging to the Enterobacteriales family were found. An increase in alpha diversity (Shannon's and Simpson's indexes) and significant alterations in beta diversity were observed. A correlation of necrotizing enterocolitis with higher Staphylococcus abundance and higher alpha diversity was also observed. H2-blockers and/or proton pump inhibitor therapy were positively correlated with a higher total bacteria number. In conclusion, these results suggest that positive changes occur in the gut microbiota profile of infants three weeks after intestinal surgery.

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.

Can physiological stimulation prior to ileostomy closure reduce postoperative ileus? A prospective multicenter pilot study

BACKGROUND

The aim of this study was to assess the impact of ileostomy closure following preoperative physiological stimulation (PPS) on postoperative ileus (POI) in patients with loop ileostomy after low anterior resection for rectal cancer.

METHODS

Patients who underwent ileostomy closure between January 2017 and February 2020 in two tertiary referral centers were prospectively included. PPS stimulation was compared to standard treatment. Stimulation was carried out daily during the 15 days prior to ileostomy closure by the patient's self-instillation of 200 ml of fecal contents from the ileostomy bag via the efferent loop, using a rectal catheter. Standard treatment (ST) consisted of observation. Outcomes measures were POI, morbidity, stimulation feasibility, and predictors to ileus.

RESULTS

A total of 58 patients were included [42 males and 16 females, median age 67 (43-85) years]. PPS was used in 24 patients, who completed the entire stimulation process, and ST in 34 patients. No differences in preoperative factors were found between the two groups. POI was significantly lower in the PPS group (4.2%) vs the ST group (32.4%); p < 0.01, OR: 0.05 (CI 95% 0.01-0.65). The PPS group had a shorter time to restoration of bowel function (1 day vs 3 days) p = 0.02 and a shorter time to tolerance of liquids (1 day vs 2 days), p = 0.04. Age (p = 0.01), open approach at index surgery, p = 0.03, adjuvant capecitabine (p = 0.01). and previous abdominal surgeries (p = 0.02) were associated with POI in the multivariate analysis. C-reactive-protein values on the 3rd (p = 0.02) and 5th (p < 0.01) postoperative day were also associated with POI.

CONCLUSIONS

PPS for patients who underwent ileostomy closure after low anterior resection for rectal cancer is feasible and might reduce POI.

Self-Expanding Metal Stents Do Not Adversely Affect Long-term Outcomes in Acute Malignant Large-Bowel Obstruction: A Retrospective Analysis

BACKGROUND

Self-expanding metal stents as a bridge to surgery in acute malignant large-bowel obstruction has gained popularity. However, long-term oncologic outcomes have not been well established.

OBJECTIVE

To investigate long-term oncologic outcomes of patients undergoing curative resection after the placement of a colonic stent compared with emergency surgery for acute malignant large-bowel obstruction.

DESIGN

This is a retrospective study.

SETTING

All patients presenting at 3 tertiary care centers between April 2002 and December 2012 with a diagnosis of complete malignant large-bowel obstruction were reviewed. Patients with disease distal to the hepatic flexure were selected for analysis.

PATIENTS

One hundred twenty-two patients who underwent either emergency surgery or placement of a colonic stent with curative intent were included.

INTERVENTIONS

Patients receiving emergency surgery within 24 hours of presenting with obstructive symptoms, including those with failed stents, were included in the emergency surgery group. All patients with clinically successful stent deployment before surgery were included in the stent group.

MAIN OUTCOME MEASURES

Overall survival and disease-free survival were calculated using the Kaplan-Meier method.

RESULTS

Sixty-four patients underwent emergency surgery, and 58 patients underwent placement of a self-expanding metal stent. Groups were similar in terms of sex, tumor stage and grade, and Charlson and Charlson-Age Comorbidity Index scores. Patients in the surgery group were older than patients in the stent group. There were no differences in the number of lymph nodes harvested, positive nodes, rates of vascular and perineural invasion, or utilization of chemotherapy. Thirty-day mortality after resection was similar between groups (7.41% vs 4.41%; p > 0.05). Patients who underwent colonic stenting as a bridge to surgery had similar 10-year overall survival (40.5% vs 32.7%; p = 0.13) and 10-year disease-free survival (40.2% vs 33.8%; p = 0.26) compared with those who underwent emergency surgery. Similar results were seen on intention-to-treat analysis.

LIMITATIONS

This was a small retrospective study.

CONCLUSIONS

Stent insertion followed by oncologic resection is associated with similar overall survival and disease-free survival compared with emergency resection. Stent insertion as a bridge to surgery should be considered in patients presenting with malignant colorectal obstruction.

ANTECEDENTES

Los stents metálicos autoexpandibles como puente a una cirugía en la obstrucción maligna aguda del colon han ganado popularidad. Sin embargo, no se han establecido bien los resultados oncológicos a largo plazo.

OBJETIVO

Investigar los resultados oncológicos a largo plazo de los pacientes sometidos a resección curativa después de la colocación de un stent colónico en comparación con la cirugía de urgencia para la obstrucción maligna aguda del colon.

DISEO

Estudio retrospectivo.

MBITO

Entre abril de 2002 y diciembre de 2012, se revisaron todos los pacientes que acudieron a tres centros de tercer nivel con un diagnóstico de obstrucción maligna completa del colon. Se seleccionaron para el análisis los pacientes con enfermedad distal al ángulo hepático.

PACIENTES

Se incluyeron 122 pacientes que fueron operados de urgencia o a una colocación de un stent colónico con intención curativa.

PROCEDIMIENTOS

Los pacientes que se sometieron a cirugía de urgencia dentro de las 24 horas posteriores a la presentación de síntomas obstructivos; se incluyeron aquellos con stents fallidos en el grupo de cirugía de urgencia. Todos los pacientes con colocación clínicamente exitosa del stent antes de la cirugía se incluyeron en el grupo de stent.

PRINCIPALES VARIABLES ANALIZADAS

La sobrevida global y la sobrevida libre de enfermedad se calcularon mediante el método de Kaplan-Meier.

RESULTADOS

Sesenta y cuatro pacientes fueron llevados a cirugía urgente y en 58 pacientes se colocó de un stent metálico autoexpandible. Los grupos fueron similares en relación a sexo, estadio y grado del tumor, puntuación de comorbilidad de Charlson y Charlson-Age. Los pacientes del grupo de cirugía eran mayores que los del grupo de stents. No hubo diferencias en el número de ganglios linfáticos recolectados, ganglios positivos, tasas de invasión vascular y perineural o utilización de quimioterapia. La mortalidad a los 30 días después de la resección fue similar entre los grupos (7,41% frente a 4,41%; p> 0,05). Los pacientes que se sometieron a la colocación de un stent colónico como puente a la cirugía tuvieron una sobrevida general a diez años similar (40,5% vs 32,7%; p = 0,13) y una sobrevida libre de enfermedad a diez años (40,2% vs 33,8%, respectivamente; p = 0,26) en comparación a los operados de urgencia. Se observaron resultados similares en el análisis por intención de tratamiento.

LIMITACIONES

Estudio retrospectivo reducido.

CONCLUSIONES

La utilización de un stent y posteriormente la resección oncológica se asocia a una sobrevida general y una sobrevida libre de enfermedad similar en comparación con la resección de urgencia. La utilización de un stent como puente a la cirugía debe considerarse en pacientes que presentan obstrucción colorrectal maligna. Consulte Video Resumen en http://links.lww.com/DCR/B714.

Effects of anchoring sutures at diverting ileostomy after rectal cancer surgery on peritoneal adhesion at following ileostomy reversal

Purpose

During diverting ileostomy reversal for rectal cancer patients who underwent previous sphincter-saving surgery, the extent of adhesion formation around the ileostomy site affects operative and postoperative outcomes. Anchoring sutures placed at the time of the ileostomy procedure may reduce adhesions around the ileostomy. This study aimed to evaluate the effects of anchoring sutures on the degree of adhesion formation and the postoperative course at the time of ileostomy reversal.

Methods

Patients who underwent sphincter-saving surgery with diverting ileostomy for rectal cancer between January 2013 and December 2017 were enrolled. Variables including the peritoneal dhesion index (PAI) score, operation time, the length of resected small bowel, operative complications, and postoperative hospital stay were collected prospectively and compared between the anchoring group (AG) and non-anchoring group (NAG).

Results

A total of 90 patients were included in this study, with 60 and 30 patients in the AG and NAG, respectively. The AG had shorter mean operation time (46.88 ± 16.37 minutes vs. 61.53 ± 19.36 minutes, P = 0.001) and lower mean PAI score (3.02 ± 2.53 vs. 5.80 ± 2.60, P = 0.001), compared with the NAG. There was no significant difference in the incidence of postoperative complications between the AG and NAG (5.0% vs. 13.3%, respectively; P = 0.240).

Conclusion

Anchoring sutures at the formation of a diverting ileostomy could decrease the adhesion score and operation time at ileostomy reversal, thus may be effective in improving perioperative outcomes.

Update on the management of sigmoid diverticulitis

Diverticular disease and diverticulitis are the most common non-cancerous pathology of the colon. It has traditionally been considered a disease of the elderly and associated with cultural and dietary habits. There has been a growing evolution in our understanding and the treatment guidelines for this disease. To provide an updated review of the epidemiology, pathogenesis, classification and highlight changes in the medical and surgical management of diverticulitis. Diverticulitis is increasingly being seen in young patients (< 50 years). Genetic contributions to diverticulitis may be larger than previously thought. Potential similarities and overlap with inflammatory bowel disease and irritable bowel syndrome exist. Computed tomography imaging represents the standard to classify the severity of diverticulitis. Modifications to the traditional Hinchey classification might serve to better delineate mild and intermediate forms as well as better classify chronic presentations of diverticulitis. Non-operative management is primarily based on antibiotics and supportive measures, but antibiotics may be omitted in mild cases. Interval colonoscopy remains advisable after an acute attack, particularly after a complicated form. Acute surgery is needed for the most severe as well as refractory cases, whereas elective resections are individualized and should be considered for chronic, smoldering, or recurrent forms and respective complications (stricture, fistula, etc.) and for patients with factors highly predictive of recurrent attacks. Diverticulitis is no longer a disease of the elderly. Our evolving understanding of diverticulitis as a clinical entity has led into a more nuanced approach in both the medical and surgical management of this common disease. Non-surgical management remains the appropriate treatment for greater than 70% of patients. In individuals with non-relenting, persistent, or recurrent symptoms and those with complicated disease and sequelae, a segmental colectomy remains the most effective surgical treatment in the acute, chronic, or elective-prophylactic setting.

Factors affecting the morbidity and mortality of diverting stoma closure: retrospective cohort analysis of twelve-year period

Background Diverting stoma is often performed in rectal cancer surgery for reducing the consequences of possible anastomotic failure. Closing of stoma follows in most cases after a few months. The aim of our study was to evaluate morbidity and mortality after diverting stoma closure and to identify risk factors for complications of this procedure. Patients and methods At our department, we have performed a retrospective cohort analysis of data for 260 patients with diverting stoma closure from 2003 to 2015. Age, stoma type, patient's preoperative ASA score, surgical technique and time to stoma closure were investigated as factors which could influence the complication rate. Results 218 patients were eligible for investigation. Postoperative complications developed in 54 patients (24.8%). Most common complications were postoperative ileus (10%) and wound infection (5%). Four patients died (1.8%). There was no effect on complication rate regarding type of stoma, closing technique, patient's ASA status and patient age. The only factor influencing the complication rate was the time to stoma closure. We found that patients which had the stoma closed prior to 8 months after primary surgery had lower overall complication rate (p<0. 05). Conclusions To reduce overall complication rate, our data suggest a shorter period than 8 months after primary surgery before closure of diverting stoma. As diverting stoma closure is not a simple operation, all strategies should be taken to reduce significant morbidity and mortality rate.

Anastomotic Leakage After Stoma Reversal Combined with Incisional Hernia Repair

BACKGROUND

Stoma reversal in patients with an incisional hernia represents a clinical dilemma, as it remains unknown whether hernia repair should be concomitantly employed. We aimed at examining postoperative complications and mortality in patients undergoing stoma reversal with or without concomitant hernia repair.

METHODS

This study included all patients subjected to stoma reversal between 2010 and 2016 at our institution. Patients were grouped according to conductance of concomitant incisional hernia repair or not. The primary outcome was anastomotic leak (AL). Secondary outcomes were surgical site occurrences (SSO), overall surgical complications, 90-day mortality and overall survival.

RESULTS

In total, 142 patients were included of whom 18 (13%) underwent concomitant hernia repair. The incidence of AL was significantly higher in patients subjected to concomitant hernia repair (four out of 18 [22.2%]) compared with patients undergoing stoma reversal alone (three out of 124 [2.4%], P = 0.002). Additional variables associated with AL were duration of surgery (P < 0.001) and ischemic heart disease (P = 0.039). Twenty-two patients (15.5%) developed a SSO: eight (44.4%) in the hernia repair group and 14 (11.3%) in the non-hernia repair group (P < 0.001). In the multivariable analysis, concomitant hernia repair remained significantly associated with development of postoperative complications (OR = 5.92, 95% CI = 1.54-25.96, P = 0.012).

CONCLUSIONS

Compared with stoma reversal alone, incisional hernia repair concomitant with stoma reversal was associated with a higher incidence of AL and other complications.

Application of the cuff rectum drainage tube in total mesorectal excision for low rectal cancer: A retrospective case-controlled study

To investigate therapeutic effect of cuff rectum drainage tube (CDT) in preventing the postoperative complications of total mesorectal excision (TME) and promoting the recovery of the patients.The clinical data of 84 cases of low rectal cancer performed TME from June 2015 to June 2017 in the First Affiliated Hospital of Xiamen University were analyzed retrospectively. All the cases were performed anus-retained operation without preventive colostomy. Patients were divided into 2 groups according to the material of the anorectal drainage tube placed in the colonic cavity. Group I (CDT group) was transanal cuff rectal drainage tube placement (Patent No. ZL 201320384337.8) (n = 48), and group II (conventional group) was transanal clinical conventional drainage tube placement (n = 36). Anastomotic fistula incidence, the time of anal exsufflation, postoperative first ambulation time, intestinal function recovery time, the incidence of interrelated complications of drainage tube and postoperative hospital stay between 2 groups were analyzed retrospectively.Both postoperative first ambulation and anal exhaust time in CDT group were shorter than those in the conventional group ([2.3 ± 0.4] d vs [3.0 ± 0.2] d, P < .05; [3.3 ± 0.3] d vs [3.9 ± 0.5] d, P < .05). Meanwhile, the postoperative hospital stay of CDT group was significantly decreased than that in the conventional group ([10.3 ± 1.6] d vs [11.8 ± 1.1] d, P < .05). Significant different occurrence of complications existed in anastomotic fistula (2.1% [1/48] vs 16.7% [6/36], P < .05), frequent defecation (8.3% [4/48] vs 27.8% [10/36], P < .05), defecating unfinished feeling (12.5% [6/48] vs 30.6% [11/36], P < .05), drainage tube complication (4.2% [2/48] vs 22.2% [8/36], P < .05).The cuff rectum drainage tube may reduce incidence of anastomotic fistula after TME, shorten postoperative first ambulation and anal exsufflation time, enable faster recovery with good toleration and decrease postoperative hospital stay.

Systematic review and meta-analysis of incisional hernia post-reversal of ileostomy

PURPOSE

Incisional hernia following closure of loop ileostomy is a common problem. Assessment of the proportion of this complication is limited by small sample size and inconsistent reporting. The aim of this review was to provide an estimate of the proportion of incisional hernia following closure of loop ileostomy according to clinical and radiological diagnostic criteria and to investigate the association of bibliometric and study quality parameters with reported proportion.

METHODS

A systematic review of PubMed, Embase, CENTRAL, ISRCTN Registry and Open Grey from 2000 onwards was performed according to PRISMA standards. Reporting on the type of stoma and mesh reinforcement after closure was mandatory for inclusion, whereas studies on paediatric populations were excluded. Fixed effect or random effects models were used to calculate pooled proportion estimates. Meta-regression models were formed to explore potential heterogeneity.

RESULTS

42 studies with 7166 patients were included. The pooled estimate of the proportion of incisional hernia after ileostomy closure was 6.1% (95% confidence interval, CI 4.4-8.3%). Proportion estimates for higher quality studies and studies reporting on incisional hernia as primary outcome were 9.0% (95% CI 6.3-12.7%) and 13.1% (95% CI 8.8-19.1%). Significant between-study heterogeneity was identified (P < 0.001, I² = 87%) and the likelihood of publication bias was high (P = 0.028). Mixed effects regression showed that both year of publication (P = 0.034, Q = 4.484, df = 1.000) and defining hernia as a primary outcome (Q = 20.298, P < 0.001) were related to effect size. Method of follow-up and quality of the studies affected the proportion.

CONCLUSION

The proportion of incisional hernia at ileostomy closure site is estimated at 6.1%. Reporting incisional hernia as primary or secondary outcome, the method of diagnosis, the year of publication and methodological quality are associated with reported proportion.

Incidence and predictors of postoperative ileus after loop ileostomy closure: a systematic review and meta-analysis

INTRODUCTION

Postoperative ileus (POI) is regarded as the most clinically significant morbidity following loop ileostomy closure; however, its incidence remains poorly understood. Our objective was therefore to determine the pooled incidence of POI after loop ileostomy closure and identify risk factors associated with its development.

METHODS

We systematically searched MEDLINE (via Ovid and PubMed), Embase, the Cochrane Library, Biosis Previews, and Scopus to identify studies reporting the incidence of POI in patients who underwent loop ileostomy closure. Two independent reviewers extracted data and appraised study quality. Cumulative incidence proportions were pooled across studies using a random-effects meta-analytic model.

RESULTS

Sixty-seven studies, including 9528 patients, met our inclusion criteria. The pooled estimate of POI was 8.0% (95% CI 6.9-9.3%; I² = 74%). The estimated incidence varied by POI definition: studies with a robust definition of POI (n = 8) demonstrated the highest estimate of POI (12.4%, 95% CI 9.2-16.5%; I² = 79%) while studies that did not report an explicit POI definition (n = 38) demonstrated the lowest estimate (6.7%, 95% CI 5.3-8.3%; I² = 61%). Small bowel anastomosis technique (hand-sewn) and interval time from ileostomy creation to closure (longer time) were the factors most commonly associated with POI after loop ileostomy closure. However, most comparative studies were not powered to examine risk factors for POI.

CONCLUSIONS

POI is an important complication after loop ileostomy closure, and its incidence is dependent on its definition. More research aimed at studying this complication is required to better understand risk factors for POI after loop ileostomy closure.

Comparing Surgical Site Infection and Scar Cosmesis Between Conventional Linear Skin Closure Versus Purse-string Skin Closure in Stoma Reversal - A Randomized Controlled Trial

Introduction

Stoma closure is one of the most frequently performed surgeries. The common complications are surgical site infection (SSI) and poor scar cosmesis. Purse-string sutures are expected to have less incidence of SSI due to the free drainage of secretions from the wound and possibly the early detection of a wound infection. Compared to the conventional linear closure, the purse-string closure technique is expected to have less wound infection, improved scar cosmesis, and good patient satisfaction because of a smaller size scar. Hence, a well-structured study is required to substantiate the advantage of this technique.

Methodology

This randomized control trial was carried out for two years in a tertiary care centre in Southern India. Patients with various stoma reversals, including colostomy, as well as ileostomy reversal, were included in the study. Patients were divided into Group I - conventional linear skin suturing (n = 40) and Group II - purse-string closure (n = 40). After the closure of rectus muscle, the skin is closed using the purse-string method (subcuticular) in the experimental group.

Results

Both the groups were comparable with respect to age, gender, body mass index (BMI), the presence of co-morbidities, and indication for surgery. Stomal procedures were done (26.3%) for malignant cases. The difference in mean hospital days for both groups were statistically insignificant (11.95 vs. 9.9; p = 0.927). The incidence of SSI between the groups were statistically significant (17 vs. 3; p = 0.003). The mean Patient and Observer Scar Assessment Scoring (POSAS) scores between the groups (65.30 vs. 83.40; p = 0.012) were statistically significant. This proved significant improvement in scar cosmesis in purse-string skin closure. At one month postoperative, the purse-string group had better patient satisfaction (3.08 vs. 4.48; p = 0.001), which was evidenced by a mean Likert 3 scale score. The mean visual analogue scale (VAS) score did not show any significant difference in pain between the groups.

Conclusion

Purse-string skin closure for stoma reversal had significantly less incidence of SSI. The duration of antibiotic therapy was also less in purse-string skin closure patients as compared to linear skin closure patients. Purse-string skin closures significantly improved the scar outcome and patient satisfaction.

Transanal Tube NO COIL® after Rectal Cancer Proctectomy. The “G. Paolo II” Cancer Centre Experience

Aims and background

Covering stoma is the main method used to protect low-lying anastomosis after cancer proctectomy. Intraluminal rectal pressure could be a potential risk factor for anastomotic leakage. We present our personal experience with an alternative and original device, the transanal tube NO COIL®, evaluating its feasibility and safety based on a preliminary manometric study.

Methods

From May 1998 to March 1999, an experimental manometric study on 35 subjects was performed to assess the pathophysiological basis of intraluminal rectal pressure with or without the transanal tube. Subsequently, from April 1999 to December 2009, 184 patients (107 males, 77 females, average age 68.2 ± 10 years) with primary adenocarcinoma of the rectum (≤12 cm from anal verge) were selected. Eighty-two underwent total proctectomy and 102 subtotal proctectomy. No stoma were fashioned. At the end of the operation, the silicone transanal tube NO COIL®, 60–80 mm long, 2 mm thick with a calibre of up to 2 cm, was applied and secured to the perineal skin by two stitches, then removed on the seventhpostoperative day if no signs of leakage occurred.

Results

The intraluminal rectal pressure with transanal tube was strongly reduced from 13.8 + 8.5 mmHg to 4.8 + 3.7 mmHg (P <0.01). Nine patients (4.8%) developed an anastomotic leakage, 2 males and 7 females. In 10 patients, the transanal tube NO COIL® did not remain in situ for the planned seven days, and 18 patients suffered from ulcers in the perianal skin. Leakage subsided with conservative treatment in 4 patients, whereas 5 patients required loop colostomy. The stoma rate was 2.7%. No leakage-related deaths occurred, and overall mortality was 1.3%.

Conclusions

The transanal tube NO COIL® does not abolish the risk of anastomotic leakage but could be an alternative option to covering stoma after cancer proctectomy in selected patients. In our experience, this simple and cheap device could reduce the rate of stoma without leakage-related mortality. Further studies within a randomized controlled trial are required to better define our results.

Temporary closure of colostomy with suture before colostomy takedown improves the postoperative outcomes

PURPOSE

Temporary loop colostomy is a common surgical procedure used to avoid complications in high-risk distal anastomosis as well as pelvic inflammation. Issues regarding postoperative outcomes of colostomy takedown have been widely discussed in the literature, wound infection especially. Temporary closure of colostomy with suture before takedown was adopted in our study, which provided excellent traction to aid mobilization of stomy and avoided stool spillage to downgrade the wound classification to "clean contamination." We aimed to determine the effects of the procedure on postoperative outcomes.

METHODS

This was a prospective case-control study at a single tertiary medical center. Patients presenting for elective colostomy takedown were included. Allis clamp (n = 50) or silk suture (n = 60) was applied to mobilize the colostomy, and results were compared. Operative time and wound infection rate were measured as primary postoperative outcomes. Univariate and multivariate analyses were used to demonstrate the association between the two groups and outcomes.

RESULTS

In univariate analyses, significantly shorter operative time (median = 57 min, p = 0.003) and lower postoperative wound infection rate (3%, p = 0.03) were noted in the group receiving silk suture. Multivariate analyses results showed that silk suture was significantly associated with both operative time (B = - 8.5, p = 0.01) and wound infection (odds ratio = 0.18, p = 0.04).

CONCLUSION

With the advantage of enhancing traction and decreasing contamination, the temporary closure of colostomy with suture improved takedown outcomes, including a shorter operative time and lower wound infection rate.

Risk Factors for Postoperative Complications Following Diverting Loop Ileostomy Takedown

INTRODUCTION

Diverting loop ileostomies are frequently created to divert the fecal stream in an effort to protect downstream anastomoses. These are later reversed to restore intestinal continuity. The goal of this study is to evaluate risk factors for postoperative complications following diverting loop ileostomy takedown.

MATERIALS AND METHODS

Patients who underwent diverting loop ileostomy takedown between January 1, 2010 and April 28, 2015 were identified in the Michigan Surgical Quality Collaborative registry. Candidate covariates were identified and a hierarchical logistic regression model was used to identify risk factors for postoperative complications.

RESULTS

1,737 patients met the inclusion criteria. Rates of postoperative complications were generally low. Mean length of stay (LOS) was 5.6 (± 4.5) days. Outcomes of interest were the following: overall morbidity, serious morbidity, extended LOS, SSI, UTI, pneumonia, readmission, reoperation, and mortality. Risk factors for these outcomes included the following: ASA class, bleeding disorder, prolonged operative time, race, tobacco use, gender, steroid use, peripheral vascular disease, weight loss, and functional status.

CONCLUSIONS

Diverting loop ileostomy takedown has a complication rate of approximately 20%. Higher ASA class, longer operative times, history of bleeding disorder, and functional status were identified as risk factors for most complications.

Risk factors for surgical site infection after stoma closure comparison between pursestring wound closure and conventional linear wound closure: Propensity score matching analysis

PURPOSE

Stoma closure has been associated with a high rate of surgical site infection (SSI) and the optimal skin closure method is still controversial. The aim of this study was to compare the short-term and long-term outcomes between the conventional linear closure (CC) and the persestring closure (PC) using propensity score matching analysis.

METHODS

We analysed the data of 360 patients who underwent stoma closure with CC or PC between January 2000 and December 2014. The propensity score was calculated from age, gender, body mass index, primary disease, type of stoma, diabetes mellitus, history of smoking, steroid use, the American Society of Anesthesiologists score, Prognostic Nutritional Index and modified Glasgow Prognostic Score.

RESULTS

There was no difference in operative variables between the two groups. The CC group and the PC group were comparable with regards to overall SSI (25.0 vs. 7.8%; P = 0.007), superficial SSI (21.9 vs. 4.7%; P = 0.003). Significant risk factor for SSI was conventional linear closure (OR, 4.14; 95% CI, 1.448-13.91).

CONCLUSION

Our study suggests that a pursestring stoma closure leads to less SSI.

Institutional Experience with Ostomies Created During Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemoperfusion

BACKGROUND

Cytoreductive surgery and hyperthermic intraperitoneal chemoperfusion (CRS-HIPEC) is a complex procedure that often requires ostomy creation to protect high-risk anastomoses. This study aimed to evaluate the authors' institutional experience with CRS-HIPEC-associated ostomies, determine predictors of ostomy creation and reversal, and assess their impact on survival.

METHODS

The study analyzed clinicopathologic, perioperative, and oncologic data from a prospective database of 1435 CRS-HIPEC procedures for peritoneal metastases. The Kaplan-Meier method was used to estimate survival. Multivariate analyses identified associations with ostomy creation/reversal and survival.

RESULTS

Ostomies were created in 34% of the patients, most commonly loop ileostomies (82%). Loop ileostomies were reversed in the majority of patients (83%), whereas non-loop ileostomies were infrequently reversed (< 10% reversal rate). In a multivariate logistic regression model, intermediate or high tumor grade, colectomy/proctectomy, longer operative time, and lower Charlson comorbidity index were associated with loop ileostomy creation, whereas incomplete macroscopic resection, colorectal histology, and major postoperative complications were associated with non-reversal of loop ileostomy. In a multivariate Cox proportional hazards model, intermediate or high tumor grade and non-reversal of loop ileostomy were associated with worse overall survival.

CONCLUSIONS

Loop ileostomies were almost always reversed, whereas non-loop ileostomies were almost always permanent. Hospital readmissions for loop ileostomy-related complications were common. Therefore, formal outpatient protocols for prevention and management should be implemented. Non-reversal of loop ileostomy was associated with very poor survival.

Assessing trends in laparoscopic colostomy reversal and evaluating outcomes when compared to open procedures

BACKGROUND

Laparoscopic colostomy reversal has emerged as a viable option for Hartmann's reversal but the trends in national adoption and postoperative complications are unknown. This study evaluates the practice trends for laparoscopic colostomy and compares complications, length of stay, and operative times between laparoscopic and open colostomy reversal.

METHODS

All patients who had open or laparoscopic colostomy reversal surgery (current procedure codes: 44227 and 44626) between 2005 and 2014 were identified from the American College of Surgeons National Surgical Quality Improvement Program. Data collected included patient demographics, comorbid conditions, postsurgical diagnosis, and estimated probabilities of morbidity and mortality. Univariate and multivariate unconditional logistic regression models and linear regression models were employed to evaluate the associations between various outcomes and surgical specialties.

RESULTS

The reported volume of both open and laparoscopic colostomy reversal surgeries increased over time, but the percentage of open reversal surgery decreased from 100% in 2005 to 74.2% in 2014. The average annual increase in percentage of laparoscopic colostomy reversal surgery was 2.87%. The complication rates of open colostomy reversal surgery were significantly higher than the rates of laparoscopic colostomy reversal surgery (P < 0.0001). Although there were fluctuations, the complication rates remained constant over the 9-year study period for both open and laparoscopic colostomy reversal surgeries. The total hospital length of stay among patients who had laparoscopic colostomy reversal surgery was shorter compared to patients who had open colostomy reversal surgery [mean change (MC) = -1.77 days, P < 0.0001]. Similarly, a shorter operation time was also observed for patients who had laparoscopic colostomy reversal surgery (MC = -26.48 min, P < 0.0001).

CONCLUSION

Based on the NSQIP database, laparoscopic colostomy reversal is increasing steadily year over year from 2005 to 2014 in NSQIP participating hospitals. Overall complication rates and length of stay are significantly lower and sustained throughout the study period for laparoscopic reversal.

Transanal tube placement for prevention of anastomotic leakage following low anterior resection for rectal cancer: a systematic review and meta-analysis

Purpose

Anastomotic leakage following low anterior resection (LAR) for rectal cancer is a serious complication that increases morbidity and mortality rates. Transanal tube placement may reduce postoperative anastomotic leakage rate by reducing intraluminal pressure and preventing fecal extrusion through the staple line. This meta-analysis evaluated the effectiveness of transanal tube placement to prevent anastomotic leakage after LAR for rectal cancer using a stapling technique.

Methods

A systematic review of the literature was consistent with the recommendations of the PRISMA (preferred reporting items for systematic reviews and meta-analyses) statement. Multiple comprehensive databases, including PubMed, Embase, Cochrane Library and KoreaMed, were searched. The main study outcomes were anastomotic leakage.

Results

Two randomized clinical trials and 4 nonrandomized studies involving 1,118 patients were included. Subgroup analyses of randomized clinical trials found that transanal tube placement had no effect on study outcomes. Meta-analysis of nonrandomized studies showed that transanal tube placement was associated with a lower incidence of anastomotic leakage (relative risk, 0.32; 95% CI, 0.15-0.67; I² = 0%).

Conclusion

Transanal tube placement may be effective in preventing or reducing the occurrence of anastomotic leakage after LAR for rectal cancer using a stapling technique. Randomized clinical trials with sufficient power are needed to confirm the benefit of transanal tube placement.

Complications after Loop Ileostomy Closure: A Retrospective Analysis of 132 Patients

BACKGROUND

Closure of a loop ileostomy is a relatively simple procedure although many studies have demonstrated high morbidity rates following it. Methods to reduce the number of complications, such as timing of closure or different surgical closure techniques, are investigated. The aim of this study was to evaluate the experience of the Abdominal Surgery Center at Vilnius University Hospital (VUH) 'Santariskiu klinikos' to review the complications after closure of loop ileostomy and to identify potential risk factors for postoperative complications.

METHODS

Data from 132 patients who underwent closure of loop ileostomy from 2003 to 2013 at the Abdominal Surgery Center of VUH were collected, including demographics, causes of ileostomy formation, additional diseases, time from creation to closure of ileostomy, anastomotic technique, duration of the operation, postoperative complications, and hospital stay after surgery. The operations were performed by 15 surgeons with varying experience assisted by surgical residents. Experience in ileostomy closure was defined by the number of procedures performed.

RESULTS

Complications occurred in 24 patients (18.2%), with 20 of them having surgical complications: bowel obstruction (9 (6.8%)), wound infection (4 (3.0%)), peritonitis due to anastomotic leak (3 (2.3%)), intra-abdominal abscess (2 (1.5%)), anastomotic leak with enterocutaneous fistula (1 (0.76%)), and bleeding (1 (0.76%)). 4 patients had non-surgical complications: postoperative diarrhea (2 (1.5%)), urinary retention (1 (0.76%)), and deep vein thrombosis (1 (0.76%)). Most complications were classified as group II according to the Clavien-Dindo classification. 2 patients died (1.5%). The anastomotic technique used did not affect the outcome. The experience of the surgeon as judged by the frequency of the procedure was the main factor affecting postoperative morbidity significantly (p = 0.03).

CONCLUSION

Our study revealed that the rate of postoperative complications and a smooth postoperative course after the closure of ileostomy was influenced by surgical experience.

Stoma Creation and Reversal After Cytoreductive Surgery with Hyperthermic Intraperitoneal Chemotherapy

INTRODUCTION

Cytoreductive surgery with heated intraperitoneal chemotherapy (CRS/HIPEC) often includes stoma creation. We evaluated the indications, morbidity, and mortality associated with stoma creation and reversal after CRS/HIPEC.

METHODS

Retrospective analysis of a prospective database of 1149 CRS-HIPEC procedures was performed. Patient demographics, type of malignancy, comorbidities, Clavien-graded morbidity, mortality, indications for stoma creation, and outcomes of subsequent reversal were abstracted.

RESULTS

Sixteen percent (186/1149) of CRS/HIPEC procedures included stoma creation, whereas 1.1 % (11/963) of patients without initial stoma creation developed anastomotic leaks requiring stoma. Patients who required a stoma had worse preoperative performance status (ECOG 0/1: 77.2 vs. 86.1 %, p = 0.002), greater burden of disease (PCI 17.6 vs. 12.9, p < 0.0001), and were more likely to have R2 resections (74.5 vs. 48.8 %, p < 0.0001) than those without stoma creation. Stomas were intended to be permanent in 17.5 % (35/199). Of 164 patients with potentially reversible ostomies, only 26.2 % (43/164) underwent reversal. Disease progression (43/164, 26.2 %) and death (40/164, 24.3 %) most commonly precluded reversal. After reversal, 27.9 % (12/43) suffered a Clavien I/II morbidity, 27.9 % (12/43) suffered Clavien III/IV morbidity, and 30-day mortality was 4.7 % (2/43). Anastomotic leak occurred after 9 % (3/33) of ileostomy and 10 % (1/10) of colostomy reversals.

CONCLUSIONS

Stomas are more common among CRS/HIPEC patients with a high burden of disease and poor functional status. Reversal is uncommon and is associated with significant major morbidity. Preoperative counseling for those with high disease burden and poor functional status should include the risk of permanent stoma.

Meta-analysis of defunctioning stoma in low anterior resection with total mesorectal excision for rectal cancer: evidence based on thirteen studies

BACKGROUND

Recent studies have shown that a protective stoma can reduce morbidity in low anterior resection for rectal cancer; however, the necessity of it is still controversially discussed.

METHODS

We performed this meta-analysis to provide a comprehensive evaluation of the role of defunctioning stoma in low anterior resection for rectal cancer on the rates of anastomotic leakage and reoperation related to leakage with or without defunctioning stoma by calculating the pooled risk ratio.

RESULTS

Studies and relevant literature published between 2004 and 2014 regarding the construction of a protective stoma after low anterior resection were searched though PubMed and EMBASE databases. Finally, a total of 13 studies including 8,002 patients were included in this meta-analysis. The results indicated that protective stomas significantly reduced the rate of postoperative anastomotic leakage and reoperation after low anterior rectal resection. The pooled risk ratios were 0.47 (95% CI: 0.33-0.68, P <0.0001) and 0.36 (95% CI: 028-0.46, P <0.00001), respectively.

CONCLUSIONS

The findings from this present meta-analysis suggest that a defunctioning stoma could effectively reduce the clinical consequences of anastomotic leakage and reoperation, it is recommended in patients undergoing low rectal anterior resection for rectal cancer.

Ostomy Closures in Children: Variations in Perioperative Care Do Not Change the Outcome

This study aimed to evaluate ostomy closure applications and outcomes and determine the effect of personal differences among surgeons on patient postoperative course. Ninety-eight patients who underwent elective ostomy (ileostomy and colostomy) closure for 8 years at a pediatric surgery training department were investigated. Postoperative complications included superficial surgical site infection (SSI; 9.4 %), organ/cavity infection (1 %), small bowel adhesions (8.2 %), and incisional hernia (1 %). SSI and postoperative complications were not affected by the preoperative antibiotic regimen used. Operation duration, pre- and postoperative antibiotic use durations, postoperative inpatient period, ostomy type, primary diagnosis, performance of abdominal exploration, SSI, and postoperative complications were not significantly different. However, the time of nasogastric (NG) tube withdrawal, time to oral feeding initiation, abdominal closure method used, and preoperative antibiotic regimen were significantly different among different surgeons. We conclude that while surgeons used different preoperative antibiotic regimens and abdominal closure methods and stipulated different times for NG tube withdrawal and oral feeding initiation, the postoperative course and prognosis were unaffected Thus, the pre- and postoperative inpatient period and antibiotic use duration can be decreased in children by procedure standardization using practice guidelines; the procedures can also be performed with a more aesthetic, acceptable incision.

Role of protective stoma in low anterior resection for rectal cancer: A meta-analysis

AIM: To provide a comprehensive evaluation of the role of a protective stoma in low anterior resection (LAR) for rectal cancer.

METHODS: The PubMed, EMBASE, and MEDLINE databases were searched for studies and relevant literature published between 2007 and 2014 regarding the construction of a protective stoma during LAR. A pooled risk ratio (RR) with 95% confidence intervals (CIs) was used to assess the outcomes of the studies, including the rate of postoperative anastomotic leakage and reoperations related to leakage. Funnel plots and Egger’s tests were used to evaluate the publication biases of the studies. P values < 0.05 were considered statistically significant.

RESULTS: A total of 11 studies were included in the meta-analysis. In total, 5612 patients were examined, 2868 of whom had a protective stoma and 2744 of whom did not. The sample size of the studies varied from 34 to 1912 patients. All studies reported the number of patients who developed an anastomotic leakage and required a reoperation related to leakage. A random effects model was used to calculate the pooled RR with the corresponding 95%CI because obvious heterogeneity was observed among the 11 studies (I² = 77%). The results indicated that the creation of a protective stoma during LAR significantly reduces the rate of anastomotic leakage and the number of reoperations related to leakage, with pooled RRs of 0.38 (95%CI: 0.30-0.48, P < 0.00001) and 0.37 (95%CI: 0.29-0.48, P < 0.00001), respectively. The shape of the funnel plot did not reveal any evidence of obvious asymmetry.

CONCLUSION: The presence of a protective stoma effectively decreased the incidences of anastomotic leakage and reoperation and is recommended in patients undergoing low rectal anterior resections for rectal cancer.

Enterostomy closure timing for minimizing postoperative complications in premature infants

BACKGROUND

For premature infants with advanced acute abdomen, creating a temporary enterostomy is believed to be an appropriate surgical management. However, there is no consensus regarding the timing of enterostomy reversal. The aim of this study was to determine the optimal timing for enterostomy closure (EC) by analyzing EC-related complications.

METHODS

This was a retrospective study of preterm infants who underwent enterostomy for suspected acute abdomens and subsequent closure.

RESULTS

EC-related complications occurred in 35 of 54 infants (65%). A univariate analysis determined the following risk factors for EC-related complications: lower weight and younger age at the time of EC and a shorter stoma duration. In a multiple logistic regression analysis, the only significant risk factor was a weight under 2660 g at the time of the closure operation. Infants with EC-related complications were ventilated longer, were administered more vasopressors, and were more likely to undergo reoperation. Additionally, these infants required parenteral nutrition for a longer duration, had a longer length of hospital stay after EC, and had a significantly lower weight and height at a corrected age of 7-10 months than infants without EC-related complications.

CONCLUSION

Body weight may be one of the most important factors to consider for minimizing EC-related complications.

Mechanically powered ambulatory negative pressure wound therapy device for treatment of a colostomy takedown site

BACKGROUND

The management of postostomy takedown surgical wound sites can be challenging. Complications from these contaminated wounds can lead to serious complications such as hernia formation and increased healthcare costs. Negative pressure wound therapy (NPWT) has been shown to be potentially helpful in managing these heavily colonized wound sites. We report the case of a mechanically powered ambulatory NPWT device (SNaP Wound Care System; Spiracur Inc, Sunnyvale, California) for treating these postcolostomy takedown wounds.

CASE

A young 9-year-old boy in Port-Au-Prince, Haiti, had under gone colostomy as a protective measure after pelvic fracture 5 months prior. Having healed the pelvic fracture and being fully ambulatory, he underwent takedown of his colostomy with reanastomosis of the bowel. At the completion of surgery, the ostomy wound site was managed by a mechanically powered NPWT device. This allowed the patient to remain ambulatory without the need for attachment to a heavier electrically powered NPWT device during healing. Dressing changes were limited to twice weekly instead of 3 times daily.

CONCLUSION

This case demonstrates the feasibility of an underdescribed application for a new mechanically powered ambulatory negative pressure device. Findings from this case study suggest that this device may be clinically applicable for patients undergoing ostomy takedown in the United States and in developing nations such as Haiti.

Abdominal wall closure after a stomal reversal procedure

The closure of a temporary stoma involves 2 different surgical procedures: the stoma reversal procedure and the abdominal wall reconstruction of the stoma site. The management of the abdominal wall has different areas that should be analyzed such us how to avoid surgical site infection (SSI), the technique to be used in case of a concomitant hernia at the stoma site or to prevent an incisional hernia in the future, how to deal with the incision when the stoma reversal procedure is performed by laparoscopy and how to close the skin at the stoma site. The aim of this paper is to analyze these aspects in relation to abdominal wall reconstruction during a stoma reversal procedure.

Does primary closure increase surgical site infection after intestinal stoma reversal? A retrospective cohort study

BACKGROUND

This study was undertaken to test the veracity of the hypothesis that primary incision closure after intestinal stoma reversal in adult patients is associated with a greater risk of surgical site infection (SSI) than are open incisions.

METHODS

A retrospective cohort study was conducted at the Surgical Department of the Aga Khan University Hospital, Karachi, Pakistan. The study included adult patients who underwent elective loop and double-barreled intestinal stoma (ileostomy or colostomy) reversal through peristomal incisions between January 2005 and May 2011. Files were reviewed independently by two surgeons to establish main exposure (closed or open surgical sites) and outcome; i.e., SSI based on U.S. Centers for Disease Control and Prevention criteria.

RESULTS

Sample size calculation prior to the study required 71 patients to be included in each exposure arm. Patients with closed surgical sites were relatively younger (mean 36±15 [standard deviation] years) than those with open surgical sites (41±15 years), with a male preponderance in both groups. Fifteen patients were found to have SSI: 3/71 (4.2%) in open and 12/71 (16.9%) in closed incisions. The risk of SSI in closed surgical sites was 5.8 times greater than in open sites (95% confidence interval for relative risk 1.5-22.5) after adjusting for gender, body mass index (BMI), site of stoma, malignant disease, and preoperative chemo-radiotherapy.

CONCLUSION

The risk of SSI in closed incisions is greater than that in open incisions. It is suggested that incisions not be closed primarily in patients undergoing stoma reversal.

Impact of Clostridium difficile colitis following closure of a diverting loop ileostomy: results of a matched cohort study

AIM

Previous reports describing Clostridium difficile colitis (CDC) developing after the closure of a loop ileostomy suggest it is severe. In this study the incidence of CDC following ileostomy closure and its effect on the postoperative outcome have been studied.

METHOD

Patients undergoing closure of loop ileostomy from 2004 to 2008 were analysed using the Nationwide Inpatient Sample. Patients who developed postoperative CDC (n = 217) were matched 10:1 to a propensity-score-matched cohort of patients without CDC (n = 13 245). Linear and logistic regression were used to examine the effect of CDC on hospital cost (US dollars), length of stay and mortality rates. Population resampling was performed using nearest neighbour bootstrapping to confirm the validity of the results.

RESULTS

The incidence of CDC following ileostomy closure was 16 per 1000 patients. The mean length of stay was 11.5 days longer among CDC patients (P < 0.0001), with a greater cost of hospitalization of US$21 240 (P < 0.0001). There was no difference in mortality between the cohorts.

CONCLUSION

CDC following ileostomy closure is an uncommon, costly and morbid complication. Patients undergoing stoma closure are at high risk for an adverse outcome if they have CDC. Should it develop they should be aggressively treated.

Liposome bupivacaine (EXPAREL®) for extended pain relief in patients undergoing ileostomy reversal at a single institution with a fast-track discharge protocol: an IMPROVE Phase IV health economics trial

Background

Postoperative opioid use following ileostomy reversal procedures contributes to postoperative ileus. We assessed the impact of a liposome bupivacaine-based, opioid-sparing multimodal analgesia regimen versus a standard opioid-based analgesia regimen on postsurgical opioid use. We also assessed health economic outcomes in patients undergoing ileostomy reversal at our institution, which employs an enhanced recovery discharge protocol.

Methods

In this single-center, open-label study, patients undergoing ileostomy reversal received postsurgical pain therapy via multimodal analgesia that included a single intraoperative administration of liposome bupivacaine or opioid-based patient-controlled analgesia (PCA) with intravenous morphine or hydromorphone. Rescue analgesia (intravenous [IV] opioids and/or oral opioid + acetaminophen) was available to all patients. Primary efficacy measures included postsurgical opioid use, hospital length of stay (LOS), and hospitalization costs. Secondary measures included: time to first rescue opioid use; patient satisfaction with analgesia; additional medical intervention; and opioid-related adverse events.

Results

Forty-three patients were enrolled and met eligibility criteria (IV opioid PCA group = 20; liposome bupivacaine-based multimodal analgesia group = 23). Postsurgical opioid use was significantly less in the multimodal analgesia group compared with the IV opioid PCA group (mean [standard deviation]: 38 mg [46 mg] versus 68 mg [47 mg]; P = 0.004). Postsurgical LOS between-group differences (median: 3.0 days versus 3.8 days) and geometric mean hospitalization costs (US $6,611 versus US$6,790) favored the multimodal analgesic group but did not achieve statistical significance. Median time to first opioid use was 1.1 hours versus 0.7 hours in the multimodal analgesia and IV opioid PCA groups, respectively; P = 0.035. Two patients in the multimodal analgesia group and one in the IV opioid PCA group experienced opioid-related adverse events.

Conclusion

A liposome bupivacaine-based multimodal analgesic regimen reduced postoperative opioid consumption in patients undergoing ileostomy reversal under a fast-track discharge protocol. A reduction of 21% in LOS (0.8 days) was noted which, although not statistically significant, may be considered clinically meaningful given the already aggressive fast-track discharge program.

An extended paIn relief trial utilizing the infiltration of a long-acting Multivesicular liPosome foRmulation Of bupiVacaine, EXPAREL (IMPROVE): a Phase IV health economic trial in adult patients undergoing ileostomy reversal

BACKGROUND

Opioid analgesics are effective for postsurgical pain but are associated with opioid-related adverse events, creating a significant clinical and economic burden. Gastrointestinal surgery patients are at high risk for opioid-related adverse events. We conducted a study to assess the impact of an opioid-sparing multimodal analgesia regimen with liposome bupivacaine, compared with the standard of care (intravenous [IV] opioid-based, patient-controlled analgesia [PCA]) on postsurgical opioid use and health economic outcomes in patients undergoing ileostomy reversal.

METHODS

In this open-label, multicenter study, sequential cohorts of patients undergoing ileostomy reversal received IV opioid PCA (first cohort); or multimodal analgesia including a single intraoperative administration of liposome bupivacaine (second cohort). Rescue analgesia was available to all patients. Primary outcome measures were postsurgical opioid use, hospital length of stay, and hospitalization costs. Incidence of opioid-related adverse events was also assessed.

RESULTS

Twenty-seven patients were enrolled, underwent the planned surgery, and did not meet any intraoperative exclusion criteria; 16 received liposome bupivacaine-based multimodal analgesia and eleven received the standard IV opioid PCA regimen. The multimodal regimen was associated with significant reductions in opioid use compared with the IV opioid PCA regimen (mean, 20 mg versus 112 mg; median, 6 mg versus 48 mg, respectively; P < 0.01), postsurgical length of stay (median, 3.0 days versus 5.1 days, respectively; P < 0.001), and hospitalization costs (geometric mean, $6482 versus $9282, respectively; P = 0.01).

CONCLUSION

A liposome bupivacaine-based multimodal analgesic regimen resulted in statistically significant and clinically meaningful reductions in opioid consumption, shorter length of stay, and lower inpatient costs than an IV opioid-based analgesic regimen.

Radiation-induced distal ileal obstruction complicating ileostomy closure

BACKGROUND

Radiation enteropathy is a recognized complication in patients who undergo neoadjuvant radiotherapy for locally advanced rectal cancer. Routine formation of defunctioning loop ileostomy in these patients may mask the development of stricturing, terminal ileal and radiation enteropathy which later may complicate the ileostomy closure. Our aim was to assess the preventive techniques and key warning signs.

METHODS

We present two cases of ileostomy closure in patients with occult, radiation-induced, terminal ileal stricture and review the relevant literature.

RESULTS

The first case was complicated by dehiscence of the ileal anastomosis due to undiagnosed, downstream stenosis of the irradiated terminal ileum. A similar terminal ileal stricture was diagnosed in the second case by contrast fluoroscopy enabling an elective ileocolic anastomosis. The literature indicates the importance of identifying such problems prior to loop ileostomy closure.

CONCLUSIONS

Contrast studies before loop ileostomy closure are valuable in limiting the complications of radiation-induced distal ileal obstruction in selected patients.

Randomized clinical trial of intestinal ostomy takedown comparing pursestring wound closure vs conventional closure to eliminate the risk of wound infection

BACKGROUND

The use of temporary stomas has been demonstrated to reduce septic complications, especially in high-risk anastomosis; therefore, it is necessary to reduce the number of complications secondary to ostomy takedowns, namely wound infection, anastomotic leaks, and intestinal obstruction.

OBJECTIVE

To compare the rates of superficial wound infection and patient satisfaction after pursestring closure of ostomy wound vs conventional linear closure.

DESIGN

Patients undergoing colostomy or ileostomy closure between January 2010 and February 2011 were randomly assigned to linear closure (n = 30) or pursestring closure (n = 31) of their ostomy wound. Wound infection within 30 days of surgery was defined as the presence of purulent discharge, pain, erythema, warmth, or positive culture for bacteria. Patient satisfaction, healing time, difficulty managing the wound, and limitation of activities were analyzed with the Likert questionnaire.

RESULTS

The infection rate for the control group was 36.6% (n = 11) vs 0% in the pursestring closure group (p < 0.0001). Healing time was 5.9 weeks in the linear closure group and 3.8 weeks in the pursestring group (p = 0.0002). Seventy percent of the patients with pursestring closure were very satisfied in comparison with 20% in the other group (p = 0.0001).

LIMITATIONS

This study was limited by the heterogeneity in the type of stoma in both groups.

CONCLUSION

The pursestring method resulted in the absence of infection after ostomy wound closure (shorter healing time and improved patient satisfaction).

Sutureless primary repair of colonic perforation with a degradable stent in a porcine model of fecal peritonitis

PURPOSE

Colonic perforation with fecal peritonitis is a life-threatening clinical condition. For these patients, a two-stage operation of fecal diversion and a postponed colostomy closure is generally recommended. Accordingly, a simple and feasible primary repair technique was explored.

METHODS

A sutureless banding method using a biodegradable stent and a porcine model of artificial colonic perforation were introduced. The colonic perforation model was created successfully with an open procedure in 34 pigs. The primary repair with a stent or the conventional hand-sewn control was performed 72 h later. Morbidity and mortality were recorded. Pigs in each group were also sacrificed to evaluate the healing on postoperative days (PODs) 3, 7, 14, and 90. The peripheral white blood cell counts, albumin, anastomotic bursting pressure, hydroxyproline contents, and histology data were evaluated.

RESULTS

There were 17 pigs in either group. Four pigs (23.5 %) of the control group died, but no mortality occurred in the stent group. There were no significant differences in white blood cell counts and albumin. Though anastomotic hydroxyproline contents between the two groups were comparable, the collagen per protein ratio on POD 14 in the stent group was higher, as well as the bursting pressure on PODs 3 and 7. Microscopically, the local inflammation of the cut edges in the control group was more severe, and the collagen synthesis started later.

CONCLUSIONS

A sutureless primary repair of a colonic perforation with a degradable stent is a feasible method in a porcine model of fecal peritonitis.

Historical and current trends in colon trauma

The authors discuss the evolution of the evaluation and management of colonic trauma, as well as the debate regarding primary repair versus fecal diversion. Their evidence-based review covers diagnosis, management, surgical approaches, and perioperative care of patients with colon-related trauma. The management of traumatic colon injuries has evolved significantly over the past 50 years; here the authors describe a practical approach to the treatment and management of traumatic injuries to the colon based on the most current research. However, management of traumatic colon injuries remains a challenge and continues to be associated with significant morbidity. Familiarity with the different methods to the approach and management of colonic injuries will allow surgeons to minimize unnecessary complications and mortality.

A comparative study of patients with and without associated digestive surgery in a two-stage hepatectomy setting

PURPOSE

The purpose of this study was to compare the feasibility and outcomes of two-stage hepatectomy in patients with or without accompanying digestive surgery.

METHODS

We analyzed prospectively data from 56 patients with colorectal liver metastases undergoing two-stage hepatectomy between 1995 and 2009. Patients undergoing associated digestive resection (group I, n = 32) were compared with patients without associated digestive surgery (group II, n = 17).

RESULTS

The feasibility rate was 87.5% (49 patients). Neither the type and extent of hepatectomy nor the type of chemotherapy administered differed between the two groups. The median interval between hepatectomies was 1.79 and 2.07 months for groups I and II, respectively (not significant). One patient (group I) died of liver failure after the second hepatectomy. Postoperative morbidity rates were comparable: 37.5% (group I) vs. 35.5% (group II) after the first hepatectomy and 46.9% (group I) vs. 52.9% (group II) after the second hepatectomy. The median hospital stay after the first hepatectomy was longer in group I (13.5 days) than in group II (10 days) (P < 0.01). Median follow-up was 54 months. The median overall survival (OS) was 45.8 months, and 3- and 5-year OS were 58 and 31%, respectively. Median OS was longer for group II (58 months) than for group I (34 months) (P = 0.048).

CONCLUSIONS

Digestive tract resection associated with two-stage hepatectomy does not increase postoperative mortality or morbidity nor does it lead to delay in chemotherapy or a reduction in cycles administered. The need for digestive tract surgery should not affect the surgical management of two-stage hepatectomy patients.

Low complication rate after stoma closure. Consultants attended 90% of the operations

AIM

To evaluate complications after stoma closure.

METHOD

Using a retrospective review of 997 medical records, data were collected from all patients undergoing stoma closure at the Department of Surgery P, Aarhus University Hospital, Denmark, from 1996 to 2010. Patient data after Hartmann reversal and loop-ileostomy closure were compared. Data regarding the grade of the operating surgeon and assistant were extracted.

RESULTS

Out of 997 patients, 700 (70.6%) had a loop-ileostomy closure and 172 (17.4%) had a Hartmann reversal. Postoperative mortality was 0.5%. Seven patients required re-operation (0.7%). Morbidity was registered in 31.9% of the patients, with 131 (13.1%) having early complications and 187 (18.8%) having late complications. Wound infection was the most frequent early complication, which occurred in 31 patients (3.1%). Only 10 patients (1%) had an anastomotic leak. Incisional hernia was the most frequent late complication, occurring in 92 patients (9.3%). A consultant attended 90% of the operations. Junior surgeons never performed stoma closure without supervision. Body mass index was significantly associated with the development of incisional hernia. Hartmann reversal was associated with higher rates of complications compared with loop-ileostomy closure. In patients with Hartmann reversal, stapled anastomosis was associated with stricture in 12 out of 95 cases (12.6%), whereas hand-sewn anastomosis was not associated with stricture (0 out of 64 patients; 0%; P < 0.05).

CONCLUSION

Stoma closure is associated with low rates of leakage. A favourable case mix and high degree of consultant attendance may explain the good results.

Systematic review and meta-analysis of the incidence of incisional hernia at the site of stoma closure

BACKGROUND

The incidence of incisional hernias at the site of stoma closure is surprisingly unclear. A review of the current literature was undertaken to determine how commonly this complication may occur and to assess the quality of evidence available.

METHODS

A systematic review was performed to identify studies reporting the incidence of incisional hernia after closure of an ileostomy or colostomy. Studies including children (<16 years old) and studies in which >10% of the total number were trauma patients were excluded.

RESULTS

Thirty-four studies provided outcomes for 2,729 closed stomas. Median follow-up time was 36 months but was only described in seven studies. Closure of loop ileostomies was the most commonly performed procedure (48%). The overall reported hernia rate was 7%, but with a wide range among studies (0-48%). Most studies based their hernia rates on retrospective clinical findings only. A separate analysis of three studies that were specifically designed to assess for stoma site hernias found the clinical hernia rate to be 30% (28/93) and the combined clinical/radiological hernia rate to be 35% (33/93). From 11 studies reporting reoperation rates, 51% of patients who developed a hernia required a surgical repair (34/66). There was a lower risk of hernia following reversal of ileostomy versus colostomy (odds ratio 0.28, 95% confidence interval 0.12-0.65).

CONCLUSIONS

One in three patients may develop a hernia after stoma closure, and around half of hernias that are detected require repair. Risk of hernia is greater after colostomy closure than after ileostomy closure. Clinical measures to reduce the development of these hernias warrant consideration.

The Reversal of a Protective Stoma Is Feasible Before the Complete Healing of a Colorectal Anastomotic Leak

A proximal diverting stoma is recommended in “high-risk” conditions after total mesorectal excision. The aim of the study is to assess whether, after checking the anastomosis by using a water-soluble contrast enema (WCE), the closure of the ileostomy is feasible and safe, even in the presence of a persistent radiological leak. From 2003 to 2010, 210 colorectal anastomoses were performed. Ileostomy was carried out in “high-risk” anastomosis. A radiological control was performed 2 weeks later. If a leakage was present, conservative therapy controlled by serial WCEs was prescribed. Ileostomy closure was performed in the absence of leakage or with persistent leakage without clinical signs of pelvic infections. Seventy patients (33.3%) had a protective ileostomy. Fifty-eight of these (82.9%) had an uneventful course, whereas 12 (17.1%) had clinical leakage. All 70 patients were submitted to WCE after 2 weeks. Nine of 58 patients (15.5%) and eight of 12 patients with clinical anastomotic leakage showed a leakage at radiology. All these patients were scheduled another WCE 2 months later. It showed that the anastomosis had been healed in seven patients, whereas the 10 patients with leaks remained with ostomy until the third enema 1 month later. For all these patients, closure of the ileostomy was planned despite persistent radiological and subclinical leakage. A radiological study using WCE before closure of the stoma is essential and stoma closure, in the presence of a persistent leakage, is possible in selected patients.
