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

Early postoperative complications after transverse colostomy closure, a retrospective study

BACKGROUND

Ostomy is a common surgery usually performed to protect patients from clinical symptoms caused by distal anastomotic leakage after colorectal cancer (CRC) surgery and perforation or to relieve intestinal obstruction.

AIM

To analyze the complications after transverse colostomy closure.

METHODS

Patients who underwent transverse colostomy closure from Jan 2015 to Jan 2022 were retrospectively enrolled in a single clinical center. The differences between the complication group and the no complication group were compared. Logistic regression analyses were conducted to find independent factors for overall complications or incision infection.

RESULTS

A total of 102 patients who underwent transverse colostomy closure were enrolled in the current study. Seventy (68.6%) patients underwent transverse colostomy because of CRC related causes. Postoperative complications occurred in 30 (29.4%) patients and the most frequent complication occurring after transverse colostomy closure was incision infection (46.7%). The complication group had longer hospital stays (P < 0.01). However, no potential risk factors were identified for overall complications and incision infection.

CONCLUSION

The most frequent complication occurring after transverse colostomy closure surgery in our center was incision infection. The operation time, interval from transverse colostomy to reversal, and method of anastomosis might have no impact on the postoperative complications. Surgeons should pay more attention to aseptic techniques.

A systematic review of patient risk factors for complications following stoma formation among adults undergoing colorectal surgery

BACKGROUND

Stoma formation is a commonly performed procedure both during and following colorectal surgery. When designed correctly, stomas can dramatically improve patients' quality of life, but the reverse may occur when complications arise. Given the significant negative impact of complications following stoma formation, understanding risk factors that may be mitigated pre-operatively is important.

METHOD

A systematic search of publications using MEDLINE, CINAHL, and Cochrane databases was conducted in May 2022. Data was extracted and a narrative synthesis undertaken. The evidence-based librarianship (EBL) checklist assessed the methodological quality of the included studies. The systematic review includes various research designs such as randomised controlled trials (RCT), case-control studies, and observational cohort studies written in English. Reviews, conference papers, opinion papers, and those including participants < 18 years old were excluded. No restrictions on the date of publication and study setting were applied.

RESULTS

This review included 17 studies, conducted between 2001 and 2020. The study designs were prospective audit, prospective analysis, retrospective analysis, longitudinal analysis and multivariate analysis of self-reported questionaires/surveys. Twenty-two possible risk factors for the development of stoma complications following stoma formation were identified. These include demographical risk factors, underlying medical condition, type of surgery, elective vs emergency surgery, stoma factors, surgical factors, indications for surgery and factors which may impact healing. Furthermore, high BMI, emergency surgery, and stoma type were identified as the most frequently occurring risk factors.

CONCLUSION

Given the large number of risk factors identified, the implementation of a risk stratification tool may decrease the incidence and prevalence of stoma complication development. This, in turn, would decrease the associated healthcare-related costs, and negative impact on mortality, length of stay and quality of life.

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.

Diverting stomas reduce reoperation rates for anastomotic leak but not overall reoperation rates within 30 days after anterior rectal resection: a national cohort study

PURPOSE

A diverting stoma is commonly formed to reduce the rate of anastomotic leak following anterior resection with anastomosis, although some studies question this strategy. The aim of this study was to assess the leak rates and overall complication burden after anterior resection with and without a diverting stoma.

METHODS

A 5-year national cohort with prospectively registered data of patients who underwent elective anterior resection for rectal cancer located < 15 cm from the anal verge. Data were retrieved from the Norwegian Registry for Gastrointestinal Surgery and the Norwegian Colorectal Cancer Registry. Primary end point was relaparotomy or relaparoscopy for anastomotic leak within 30 days from index surgery. Secondary endpoints were postoperative complications including reoperation for any cause.

RESULTS

Some 1018 patients were included of whom 567 had a diverting stoma and 451 had not. Rate of reoperation for anastomotic leak was 13 out of 567 (2.3%) for patients with diverting stoma and 35 out of 451 (7.8%) (p > 0.001) for patients without. In multivariable analyses not having a diverting stoma (aOR 3.77, c.i 1.97-7.24, p < 0.001) was associated with increased risk for anastomotic leak. However, there were no differences in overall reoperation rates following anterior resection with or without diverting stoma (9.3% vs 10.9%, p = 0.423), and overall complication rates were similar. Reoperation was associated with increased mortality irrespective of the main intraoperative finding.

CONCLUSION

Diverting stoma formation after anterior resection is protective against reoperation for anastomotic leak but does not affect overall rates of reoperation or complications within 30 days.

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.

Outcomes on diverting ostomy formation and reversal after low anterior resection in the older more advanced rectal cancer patient

BACKGROUND

To decrease morbidity caused by anastomotic leakages after a low anterior resection (LAR) with primary anastomosis, a diverting ostomy is often created. Reversal of a diverting ostomy is associated with morbidity, which may result in non-reversal, particularly in the elderly. This study aimed to describe the diverting ostomy-related outcomes in elderly patients with more advanced rectal cancer after LAR.

MATERIALS AND METHODS

All rectosigmoid and rectal cancer patients ≥70 years who underwent LAR with primary anastomosis between 2006 and 2019 in the Catharina Hospital (Eindhoven, The Netherlands) were included for analyses. Reversal rates, ostomy-related complications, morbidity and mortality after ostomy reversal, and definitive ostomy rates were evaluated.

RESULTS

In total 164 patients were included, of which 150 (91.5%) underwent primary or secondary ostomy creation. Ostomy-related complications were reported in 34.7% (95%-CI 27.1-42.9%). In total, 72.5% (95%-CI 64.2-79.7%) reversed their diverting ostomy. Non-reversal was mostly due to relapsing disease (52.6%). Median time to ostomy reversal was 3.2 months (IQR 2.3-5.0). No or minor complications after ostomy reversal were observed in 84.0% (95%-CI 75.3-90.6%). Over time, ostomy recreation was performed in 15.0% (95%-CI 8.6-23.5%), and ultimately 65.8% (95%-CI 57.8-73.2%) were ostomy-free after the median follow-up of 3.8 years.

CONCLUSION

Although most elderly successfully reversed their diverting ostomy after LAR with limited morbidity, attention should be paid for the risk of non-reversal and ostomy recreation over time. Preoperative patient counselling is important in every individual to be able to decide if LAR with primary anastomosis or a permanent end colostomy is preferred.

Outcomes of diverting loop ileostomy reversal in the elderly: a case-control study

BACKGROUND

Although diverting loop ileostomy (DLI) reversal is considered to be a relatively simple procedure, it is not immune from major morbidity. We aimed to compare outcomes of DLI reversal between elderly and non-elderly patients.

METHODS

Retrospective review of all patients who underwent DLI reversal at a single tertiary medical centre between 2010 and 2020. The elderly group consisted of patients 70 or older compared to a control group of those younger than 70 years.

RESULTS

During the study period, 307 patients underwent DLI reversal. Of these, 76 patients were in the elderly group (mean age 75.6) and 231 in the control group (mean age 55.3). The groups were comparable in terms of mean time interval between the creation of the ileostomy and reversal (242 versus 255 days, respectively, P = 0.5), choice between stapled and hand-sewn anastomoses (97.4% stapled anastomosis versus 93.1%, P = 0.086), median post-operative length of stay (5 days in both, P = 0.086), rates of post-operative complications (26.3% versus 26.8%, P = 0.99), severe complications (5.3% versus 6.9%, P = 0.81) and 30-day readmission rates (13.2% versus 10.8%, P = 0.58). Multivariate analysis found the time interval between the creation of the stoma and its reversal to be the only significant risk factor for major post-operative morbidity. Age was not found to be correlated with post-operative morbidity.

CONCLUSION

The outcomes of loop ileostomy reversal in elderly patients are similar to non-elderly patients. Efforts should be made to decrease the time interval between the creation of the stoma and its reversal as this is a significant risk factor for major post-operative morbidity.

Predictors of morbidity related to stoma closure after colorectal cancer surgery

PURPOSE

A defunctioning stoma is essential in reducing symptomatic leakage after colorectal surgery, particularly after lower anterior resection. Subsequent stoma closure is associated with morbidity and rarely mortality. This study aimed to identify the risk factors associated with post-operative complications related to stoma closure.

METHODS

This retrospective cohort included patients who have undergone elective stoma closure between 2015 and 2017. Patient demographics, pre-morbidities, use of systemic therapy, stoma characteristics, and post-operative complications were retrieved from electronic records. Univariate and multivariate analysis was carried out to identify risk factors of stoma closure related morbidity.

RESULTS

Ninety patients were included with a median age of 65 years, of which 58 (64.4%) of them were male. Sixty-nine (76.7%) patients had loop colostomy, while the rest had loop ileostomy. Fifty-four (60%) patients received neoadjuvant or adjuvant therapy. The median time interval from stoma creation to closure was 15 months. Nineteen (21.1%) patients had post-operative complications. The two most commonly observed post-operative complications were wound complications (16.7%) and intra-abdominal collections (6.7%). Fifteen (16.7%) patients developed an incisional hernia. The median follow-up time was 29 months. There was no 30-day mortality in this cohort. In multivariate analysis, adjuvant chemotherapy was associated with a higher risk of wound complications (p = 0.027). Higher risk of incisional hernia was seen in patients with history of hypertension (p = 0.046), use of adjuvant chemotherapy (p = 0.042) and stoma-related complications before closure (p = 0.002). Male patients might be associated with a higher risk of incisional hernia.

CONCLUSION

Adjuvant chemotherapy is associated with a higher risk of post-operative complications, particularly with wound complications. Male patients, hypertension, adjuvant chemotherapy, and stoma-related complications are associated with a higher risk of incisional hernia.

A Comprehensive Review of Randomized Clinical Trials Shaping the Landscape of Rectal Cancer Therapy

Colorectal carcinoma is the second leading cause of cancer-related deaths in the United States, with rectal cancer accounting for approximately one third of newly diagnosed cases. Surgery remains the cornerstone of curative therapy, with total mesorectal excision being the standard of care. Although minimally invasive procedures might be appropriate for a subset of patients with early-stage, superficial tumors, the standard of care for medically operable patients with nonmetastatic rectal cancer includes a comprehensive multimodality approach of neoadjuvant chemoradiotherapy, surgery with total mesorectal excision, and systemic chemotherapy. However, the morbidity and mortality related to both local and distant organ relapse have remained challenging. In the present review, we have discussed the trial-level evidence that has shaped the current clinical practice patterns in the treatment of curable, nonmetastatic rectal cancer. In addition, we have discussed the anticipated results of ongoing clinical trials and outlined pragmatic opportunities for future investigation to optimize the current status quo and, hopefully, provide prospective validation of novel approaches in the treatment of rectal cancer.
