Multiple ileal perforations as late complications of electrical injury: A rare case report

Introduction

Electric injury-induced intestinal perforation is one of rare and lethal complications. Direct injury and ischemic changes are the mechanism of intestinal perforation. Proper surgical and non-surgical management may increase the survival chance.

Case presentation

A 21-year-old male was referred from rural hospital with history of electric burn injury two days before. On arrival, the patient started complaining bloating and abdominal x-ray revealed small intestine dilation. On fourth day post-event, the symptoms worsened and abdominal CT-scan revealed free peritoneal air. Exploratory laparotomy was performed, and two ileal perforations were found. Suturing of perforation and ileostomy were performed. Forequarter amputation of the right superior limb was performed on the seventh day post-event. On the third month, the ileostomy was closed.

Conclusion

Intestinal perforation may be one of late complications of electrical injury in abdomen. Proper clinical evaluation and management helps in morbidity and mortality reduction.

Modified 2-stage IPAA has similar postoperative complication rates and functional outcomes compared to 3-stage IPAA

INTRODUCTION

Reconstructive ileal-pouch anal anastomosis (IPAA) for ulcerative colitis (UC) is often created in 3-stages: colectomy ​+ ​ileostomy, proctectomy ​+ ​pouch creation with diverting loop ileostomy, then subsequent ileostomy closure. Modified 2-stage IPAA is without pouch diversion, thus avoiding a third operation. This study compares perioperative complications, quality of life (QOL) and functional outcomes of 3- versus modified 2-stage IPAA.

METHODS

Charts were reviewed for adult UC patients undergoing IPAA between 2010 and 2020. QOL and function were assessed with EQ-5D-3L Quality of Life and Pouch Functional Score questionnaires.

RESULTS

152 patients were identified. 43 modified 2-stage and 109 3-stage IPAA were similar for anastomotic leak (9.3% vs. 1.8%, p ​= ​0.06), SSI (34.9% vs. 29.7%, p ​= ​0.51) and ileus (32.6% vs. 33%, p ​= ​0.96). Modified 2-stage had less bowel obstruction than 3-stage IPAA (7.0% vs. 30.1%, p ​= ​0.006). 92 patients returned questionnaires with similar QOL and pouch function.

CONCLUSIONS

Perioperative complications, QOL and function are similar for 3-stage IPAA and modified 2-stage IPAA. Modified 2-stage IPAA in select patients is safe and has less postoperative bowel obstruction than 3-stage IPAA.

Prophylactic Biosynthetic Retrorectus Mesh Placement During Stoma Reversal Reduces the Rate of Stoma Site Incisional Hernia

INTRODUCTION

Stoma site incisional hernias (SSIHs) are associated with substantial long-term morbidity, and the rate can be as high as 30% to 40%. Recent efforts using prophylactic mesh reinforcement (PMR) to reduce the development of hernias have shown encouraging outcomes. The objective of this study was to assess the use of prophylactic biosynthetic mesh at the time of stoma reversal on the overall SSIH rate.

METHODS

This is an observational retrospective cohort study. A review of 101 consecutive patients who underwent PMR in the retrorectus plane from 2015 to 2020 was compared to 73 consecutive patients who underwent primary stoma closure without mesh from 2011 to 2014. The primary endpoint was the presence of SSIH on clinical examination or computed tomography after ostomy takedown.

RESULTS

In total, 174 cases were analyzed with 101 patients in the treatment group (median follow-up 45.2 months) and 73 patients in the control group (median follow-up 43.2 months). There were no major differences in preoperative characteristics between the groups. Fourteen patients developed SSIHs with 1 (1.0%) in the treatment arm and 13 (17.8%) in the control arm (p = 0.001). The majority of stomas were loop ileostomies and end colostomies, and stoma type did not affect hernia rates. On univariate analysis, body mass index (p = 0.029) and chronic kidney disease < 3 (p = 0.003) were independent predictors of hernia formation, while mesh was significantly protective (p = 0.000057).

DISCUSSION

PMR with biosynthetic mesh at the time of stoma reversal and closure is an effective procedure to reduce the incidence of SSIHs and does not seem to be associated with an increased risk of complications.

Reinforced tissue matrix to strengthen the abdominal wall following reversal of temporary ostomies or to treat incisional hernias

BACKGROUND

Abdominal wall deficiencies or weakness are a common complication of temporary ostomies, and incisional hernias frequently develop after colostomy or ileostomy takedown. The use of synthetic meshes to reinforce the abdominal wall has reduced hernia occurrence. Biologic meshes have also been used to enhance healing, particularly in contaminated conditions. Reinforced tissue matrices (RTMs), which include a biologic scaffold of native extracellular matrix and a synthetic component for added strength/durability, are designed to take advantage of aspects of both synthetic and biologic materials. To date, RTMs have not been reported to reinforce the abdominal wall following stoma reversal.

AIM

To evaluate the effectiveness of using an RTM to reinforce the abdominal wall at stoma takedown sites.

METHODS

Twenty-eight patients were selected with a parastomal and/or incisional hernia who had received a temporary ileostomy or colostomy for fecal diversion after rectal cancer treatment or trauma. Following hernia repair and proximal stoma closure, RTM (OviTex® 1S permanent or OviTex® LPR) was placed to reinforce the abdominal wall using a laparoscopic, robotic, or open surgical approach. Post-operative follow-up was performed at 1 month and 1 year. Hernia recurrence was determined by physical examination and, when necessary, via computed tomography scan. Secondary endpoints included length of hospital stay, time to return to work, and hospital readmissions. Evaluated complications of the wound/repair site included presence of surgical site infection, seroma, hematoma, wound dehiscence, or fistula formation.

RESULTS

The observational study cohort included 16 male and 12 female patients with average age of 58.5 years ± 16.3 years and average body mass index of 26.2 kg/m2 ± 4.1 kg/m2. Patients presented with a parastomal hernia (75.0%), incisional hernia (14.3%), or combined parastomal/incisional hernia (10.7%). Using a laparoscopic (53.6%), robotic (35.7%), or open (10.7%) technique, RTMs (OviTex® LPR: 82.1%, OviTex® 1S: 17.9%) were placed using sublay (82.1%) or intraperitoneal onlay (IPOM; 17.9%) mesh positioning. At 1-month and 1-year follow-ups, there were no hernia recurrences (0%). Average hospital stays were 2.1 d ± 1.2 d and return to work occurred at 8.3 post-operative days ± 3.0 post-operative days. Three patients (10.7%) were readmitted before the 1-month follow up due to mesh infection and/or gastrointestinal issues. Fistula and mesh infection were observed in two patients each (7.1%), leading to partial mesh removal in one patient (3.6%). There were no complications between 1 month and 1 year (0%).

CONCLUSION

RTMs were used successfully to treat parastomal and incisional hernias at ileostomy reversal, with no hernia recurrences and favorable outcomes after 1-month and 1-year.

Surgical outcomes of very-early-onset ulcerative colitis: retrospective comparative study with older pediatric patients

PURPOSE

The study compares the surgical outcomes of very-early-onset ulcerative colitis (VEO-UC), which is a rare disease diagnosed in pediatric patients < 6 years, with those of older pediatric patients with ulcerative colitis (UC).

METHODS

A retrospective observational study of 57 pediatric patients with UC was conducted at a single center. The study compared surgical complications and postoperative growth between the two groups.

RESULTS

Out of the 57 patients, 6 had VEO-UC, and 5 of them underwent total colectomy. Compared with the surgical cases of older patients with UC (n = 6), the rate of postoperative complications in patients with VEO-UC (n = 5) was not significantly different, except for high-output ileostomy (80% vs. 0% at 3 weeks postoperatively, p = 0.02). The rate of postoperative central venous catheter (CVC) placement at > 90 days was higher in patients with VEO-UC (100% vs. 17%, p = 0.02). The median change in the Z-score of height before and 2 years after colectomy was not significantly different between VEO-UC and older patients (1.1 vs. 0.3, p = 0.13).

CONCLUSION

With regard to complications and outcomes, total colectomy for VEO-UC patients and that for older pediatric UC patients is comparable. However, high-output ileostomy and the long duration of CVC placement may pose management challenges.

Patient adherence to an oral rehydration solution intervention to prevent dehydration following ileostomy creation: A qualitative study

BACKGROUND

Patients undergoing surgery for ileostomy creation frequently experience postoperative dehydration and subsequent renal injury. The use of oral rehydration solutions (ORS) has been shown to prevent dehydration, but compliance may be variable.

METHODS

Semi-structured qualitative interviews were conducted with 17 patients who received a postoperative hydration kit and dehydration education to assess barriers and facilitators to compliance with ORS kit instructions.

RESULTS

Qualitative analysis revealed five themes affecting patient adherence to the ORS intervention: (1) patient's perception of the effectiveness of the ORS solution, (2) existing co-morbidities, (3) kit quality and taste of the ORS product, (4) quality of the dehydration education, and (5) social support.

CONCLUSIONS

Given that patient adherence can greatly affect the success of an ORS intervention, the design of future ORS interventions should emphasize the educational component, the "patient friendliness" of the ORS kit, and ways that social supports can be leveraged to increase adherence.

Repair of parastomal hernia after Bricker procedure: retrospective consecutive experience of a tertiary center

BACKGROUND

Ileal conduit parastomal hernias (ICPHs) are frequent after radical cystectomy with ileal conduit urinary diversion, but their management is debated. This study aimed to review the results of ICPH repair according to Sugarbaker or Sandwich techniques, with special interest in ICPH recurrence and urological complications.

METHODS

The authors reviewed a consecutive series of patients undergoing ICPH repair between January 2014 and December 2020. Primary endpoints were ICPH recurrences at clinical exam and cross-sectional abdominal computed tomography (CT) scans. Secondary endpoints were any other complications possibly related to the ICPH repair.

RESULTS

Twenty-three patients underwent ICPH repair surgery (16 Sugarbaker and 7 Sandwich techniques) during the study period. Sixteen patients underwent a primary laparoscopic approach. All but one patient underwent at least one abdominal CT during the follow-up. Median clinical and CT scan follow-up times were 57 and 50.5 months, respectively. Clinical and CT ICPH recurrence rates were 4.5% and 13% at 5 years, respectively. Eighteen patients (78%) suffered no urological complications during the follow-up period, but three patients (13%) needed redo surgery on the urinary ileal conduit.

CONCLUSION

The modified Sugarbaker or Sandwich techniques might be considered as promising techniques for ICPH repair with a low rate of recurrence. The urological complications, and particularly the ileal conduit-related issues, need to be evaluated in further studies. Controlled and prospective data are required to compare the Sugarbaker and Sandwich techniques to the Keyhole approach for ICPH repairs.

Efferent limb stimulation prior to loop ileostomy closure: a systematic review and meta-analysis

BACKGROUND

Postoperative ileus (POI) remains a common phenomenon following loop ileostomy closure. Our aim was to determine whether preoperative physiological stimulation (PPS) of the efferent limb reduced POI incidence.

METHODS

A PRISMA-compliant meta-analysis searching PubMed, EMBASE and CENTRAL databases was performed. The last search was carried out on 30 January 2023. All randomized studies comparing PPS versus no stimulation were included. The primary endpoint was POI incidence. Secondary endpoints included the time to first passage of flatus/stool, time to resume oral diet, need for nasogastric tube (NGT) placement postoperatively, length of stay (LOS) and other complications. Random effects models were used to calculate pooled effect size estimates. Trial sequential analyses (TSA) were also performed.

RESULTS

Three randomized studies capturing 235 patients (116 PPS, 119 no stimulation) were included. On random effects analysis, PPS was associated with a quicker time to resume oral diet (MD - 1.47 days, 95% CI - 2.75 to - 0.19, p = 0.02), shorter LOS (MD - 1.47 days, 95% CI - 2.47 to - 0.46, p = 0.004) (MD - 1.41 days, 95% CI - 2.32 to - 0.50, p = 0.002, I2 = 56%) and fewer other complications (OR 0.42, 95% CI 0.18 to 1.01, p = 0.05). However, there was no difference in POI incidence (OR 0.35, 95% CI 0.10 to 1.21, p = 0.10), the requirement for NGT placement (OR 0.50, 95% CI 0.21 to 1.20, p = 0.12) or time to first passage of flatus/stool (MD - 0.60 days, 95% CI - 1.95 to 0.76, p = 0.39). TSA revealed imprecise estimates for all outcomes (except LOS) and further studies are warranted to meet the required information threshold.

CONCLUSIONS

PPS prior to stoma closure may reduce LOS and postoperative complications albeit without a demonstrable beneficial effect on POI. Further high-powered studies are required to confirm or refute these findings.

The economic burden of stomas in the UK: a retrospective observational study of health records and hospital encounters

BACKGROUND

Stomas divert waste from the small intestine (ileostomy), large intestine (colostomy) or ureters (urostomy), and complications are common.

AIMS

This study evaluated healthcare resource utilisation (HCRU) and costs of stomas from a UK perspective.

METHODS

This was a retrospective observational study of adults with new stomas (New Stoma Group) or new/existing stomas and >6 months of follow-up (Established Stoma Group) using health records linked with hospital encounters (January 2009-December 2018). Age- and sex-matched controls were identified for each stoma case (1:50).

FINDINGS

Both the New (n=8533) and Established (n=9397) stoma groups had significantly higher HCRU (all P<0.0001) and associated costs (all P<0.01), driven by inpatient admissions. New Stoma Group: colostomy versus controls, £3227 versus £99 per person; ileostomy, £2576 versus £78 per person; and urostomy, £2850 versus £110 per person (all P<0.0001). Findings were similar in the Established Stoma Group.

CONCLUSION

Stomas are associated with a substantial economic burden in the UK driven by hospital care. (Supplementary data tables can be obtained from the authors.).

Clinical management of high-output stoma: a systematic literature review and meta-analysis

PURPOSE

High output is a common complication after stoma formation. Although the management of high output is described in the literature, there is a lack of consensus on definitions and treatment. Our aim was to review and summarise the current best evidence.

METHODS

MEDLINE, Cochrane Library, BNI, CINAHL, EMBASE, EMCARE, and ClinicalTrials.gov were searched from 1 Jan 2000 to 31 Dec 2021 for relevant articles on adult patients with a high-output stoma. Patients with enteroatmospheric fistulas and case series/reports were excluded. Risk of bias was assessed using RoB2 and MINORS. The review was registered in PROSPERO (CRD42021226621).

RESULTS

The search strategy identified 1095 articles, of which 32 studies with 768 patients met the inclusion criteria. These studies comprised 15 randomised controlled trials, 13 non-randomised prospective trials, and 4 retrospective cohort studies. Eighteen different interventions were assessed. In the meta-analysis, there was no difference in stoma output between controls and somatostatin analogues (g - 1.72, 95% CI - 4.09 to 0.65, p = 0.11, I2 = 88%, t2 = 3.09), loperamide (g - 0.34, 95% CI - 0.69 to 0.01, p = 0.05, I2 = 0%, t2 = 0) and omeprazole (g - 0.31, 95% CI  - 2.46 to 1.84, p = 0.32, I2 = 0%, t2 = 0). Thirteen randomised trials showed high concern of bias, one some concern, and one low concern. The non-randomised/retrospective trials had a median MINORS score of 12 out of 24 (range 7-17).

CONCLUSION

There is limited high-quality evidence favouring any specific widely used drug over the others in the management of high-output stoma. Evidence, however, is weak due to inconsistent definitions, risk of bias and poor methodology in the existing studies. We recommend the development of validated core descriptor and outcomes sets, as well as patient-reported outcome measures.

Impact of chemotherapy on surgical outcomes in ileostomy reversal: a propensity score matching study from a single centre

PURPOSE

In patients with chemotherapy, there is no consensus on the timing of ileostomy closure. Ileostomy reversal could improve the quality of life and minimise the long-term adverse events of delayed closure. In this study, we evaluated the impact of chemotherapy on ileostomy closure and searched for the predictive factors for complications.

METHODS

We retrospectively analysed 212 patients with rectal cancer who underwent ileostomy closure surgery during and without chemotherapy and were consecutively enrolled between 2010 and 2016. As a result of the heterogeneity of the two groups, propensity score matching (PSM) was performed with a 1:1 PSM cohort.

RESULTS

A total of 162 patients were included in the analysis. The overall stoma closure-related complications (12.4% vs. 11.1%, p = 1.00) and major complications (2.5% vs. 6.2%, p = 0.44) were not significantly different between the two groups. Multivariate analysis demonstrated that chronic kidney disease and bevacizumab use are risk factors for major complications.

CONCLUSION

Patients with oral or intravenous chemotherapy can safely have ileostomy closure with an adequate time delay from chemotherapy. When patients use bevacizumab, major complications related to ileostomy closure should still be cautioned.

Defining the safety of early ileostomy closure after ileal pouch anal anastomosis

PURPOSE

The safety of early ileostomy reversal after ileal pouch anal anastomosis (IPAA) has not been established. Our hypothesis was that ileostomy reversal before 8 weeks is associated with negative outcomes.

METHODS

This was a retrospective cohort study from a prospectively maintained institutional database. Patients who underwent primary IPAA with ileostomy reversal between 2000 and 2021 from a Pouch Registry were stratified on the basis of timing of reversal. Those reversed before 8 weeks (early) and those reversed from 8 weeks to 116 days (routine) were compared. The primary outcome was overall complications according to timing and reason for closure.

RESULTS

Ileostomy reversal was performed early in 92 patients and routinely in 1908. Median time to closure was 49 days in the early group and 93 days in the routine group. Reasons for early reversal were stoma-related morbidity in 43.3% (n = 39) and scheduled closure in 56.7% (n = 51). The complication rate in the early group was 17.4% versus 11% in the routine group (p = 0.085). When early patients were stratified according to reason for reversal, those reversed early for stoma-related morbidity had an increased complication rate compared to the routine group (25.6% vs. 11%, p = 0.006). Patients undergoing scheduled reversal in the early group did not have increased complications (11.8% vs. 11%, p = 0.9). There was a higher likelihood of pouch anastomotic leak when reversal was performed early for stoma complications compared to routinely (OR 5.13, 95% CI 1.01-16.57, p = 0.049).

CONCLUSIONS

Early closure is safe but could be delayed in stoma morbidity as patients may experience increased complications.

Comparison of Enhanced Recovery After Surgery (ERAS) Pathway Versus Standard Care in Patients Undergoing Elective Stoma Reversal Surgery- A Randomized Controlled Trial

BACKGROUND

Practices such as prolonged preoperative fasting, bowel preparation, delayed ambulation and resumption of orals result in morbidity in 15-20% of stoma reversal cases which can be improved by Enhanced Recovery After Surgery (ERAS) pathways.

AIM

To evaluate the safety, feasibility and efficacy of ERAS pathway in patients undergoing elective loop ileostomy or colostomy reversal surgery METHODS: This was an open-labeled, superiority randomized controlled trial in which patients undergoing loop ileostomy or colostomy reversal were randomized to standard or ERAS care. Patients with ASA class ≥3, needing laparotomy for stoma reversal, cardiac, renal and neurological illnesses were excluded. Components of ERAS protocol included pre-operative carbohydrate loading, avoidance of mechanical bowel preparation, goal directed fluid therapy, avoidance of long-acting opioid anesthetics or analgesics, avoidance of drains, urinary catheter or nasogastric tube, early mobilization and early enteral feeding. The primary outcome was length of stay (LOS) while the secondary outcomes were postoperative recovery and morbidity parameters.

RESULTS

Forty patients each were randomized to standard care and ERAS. Demographic and laboratory parameters between the two groups were comparable. ERAS group patients had significantly reduced LOS (5.3 ± 0.3 vs 7 ± 2.6; mean difference: 1.73 ± 0.98; p=0.0008). Functional recovery was earlier in the ERAS group compared to the standard care group, such as early resolution of ileus (median-2 days; p<0.001), time to first stool (median-3 days; p=0.0002), time to the resumption of liquid diet (median-3 days; p<0.001) and solid diet (median-4 days; p<0.001). Surgical site infections (SSI) were significantly lesser in ERAS group (12.5% vs 32.5%; p=0.03) while postoperative nausea/vomiting (p=0.08), pulmonary complications (p=0.17) and urinary tract infections (p=0.56) were comparable in both groups.

CONCLUSION

ERAS pathways are feasible, safe and significantly reduces LOS in patients undergoing elective loop ileostomy or colostomy reversal surgery.

Cost benefit analysis and pathology review of ileostomy and colostomy specimens processed over a 20-year period

Rising healthcare costs have been linked to overtreatment and overuse of available resources. Identifying and eliminating low-value services is vital for reducing such costs. At many institutions, including ours, all ileostomy and colostomy specimens are sent for pathological evaluation. It is estimated that approximately 120,000 ileostomy/colostomy procedures are done every year, and at least 1 million patients have stomas at any given time in North America. Hence, we decided to analyze the pathological findings and cost-benefit of undertaking the pathological evaluation of these colostomy and ileostomy specimens. The pathology database of our department was searched for all ileostomy and colostomy specimens received between 2000 and 2020, resulting in a total of 2762 cases (1944 ileostomy and 818 colostomy). We performed a cost-benefit analysis and pathologic review of these cases. The results of our study show that 99.38% of these specimens did not show any significant pathological abnormality, and non-neoplastic pathologic findings accounted for 99.63% of cases. Less than 1% of our cases showed any clinically significant pathological findings. All 10 cases that showed a neoplastic or malignant diagnosis showed some abnormal finding that was appreciated at the time of gross examination. We conclude that microscopic evaluation of ileostomy and colostomy specimens incurs significant costs and provides no clear value or relevant information for patient care. The results of our study provide support for ileostomy and colostomy specimens to be triaged by gross-only pathological examination in the first instance for the vast majority of cases.

Parastomal Hernia Repair

Parastomal hernias (PHs) are common and contribute to significant patient morbidity. Despite 45 years of evolution, mesh-based PH repairs continue to be challenging to perform and remain associated with high rates of postoperative complications and recurrences. In this article, the authors summarize the critical factors to consider when evaluating a patient for PH repair. The authors provide an overview of the current techniques for repair, including both open and minimally invasive approaches. The authors detail the mesh-based repair options and review the evidence for choice of mesh to use for repair.

Protective ileostomy after low anterior resection for extraperitoneal rectal cancer: does the reversal surgery timing affect closure failure?

Loop ileostomy is commonly performed after LAR with TME to temporarily protect the anastomosis. Usually, defunctioning stoma is closed after 1-6 months, although sometimes it becomes definitive de facto. The aim of this study is to investigate the long-term risk of no-reversal of protective ileostomy after LAR for middle-low rectal cancer and the predictive risk factors. A retrospective analysis of a consecutive cohort of patients who underwent curative LAR with covering ileostomy for extraperitoneal rectal cancer in two colorectal units was performed. A different policy for scheduling stoma closure was applied between centers. All the data were collected through an electronic database (Microsoft Excel®). Descriptive statistical analysis was performed using Fisher's exact and Student's t test. Multivariate logistic regression analysis was conducted. Two-hundred twenty-two patients were analysed: reversal procedure was carried out in 193 patients, in 29 cases stoma was never closed. The mean interval time from index surgery was 4.9 months (Center1: 3 vs. Center2: 7.8). At the univariate analysis, mean age and tumor stage were significantly higher in the "no-reversal" group. Unclosed ostomies were significantly lower in Center 1 than Center 2 (8% vs. 19.6%). At the multivariate analysis female gender, anastomotic leakage and Center 2 had significant higher risk of unclosed ileostomy. Currently, no clinical recommendations have been established and the policy of scheduling stoma reversal is variable. Our study suggests that an established protocol could avoid closure delay, decreasing permanent stomas. Consequently, ileostomy closure should be weighed as standardized step in cancer therapeutic pathway.

Outcome of early versus late ileostomy closure in patients with rectal cancers undergoing low anterior resection: A prospective cohort study

BACKGROUND

Protective loop ileostomy is performed following low anterior resection (LAR) in patients with rectal cancer to reduce the complications of primary anastomosis. The optimal timing for ileostomy closure remains controversial. The aim of the current study was to compare the effects of early (<2 weeks) versus late (≥2 months) closure of the stoma in patients with rectal cancer undergoing LAR on surgical outcome and complications rates.

METHODS

This prospective cohort study was conducted in two referral centers in Shiraz, Iran, during a 2-year period. We have consecutively and prospectively included adult patients with rectal adenocarcinoma who underwent LAR followed by protective loop ileostomy in our center during the study period. The baseline, tumor characteristics and complication as well as outcome was recorded in a 1-year follow-up and was compared between early and late ileostomy closure.

RESULTS

Overall, 69 patients (32 in early and 37 in late group) were included. The mean age of the patients was 59.40 ± 9.30 years and there were 46 (66.7%) men and 23 (33.3%) women. Patients undergoing early closure of the ileostomy had significantly shorter operation duration (p<0.001) and lower intraoperative bleeding (p<0.001) compared to late ileostomy closure. There was no significant difference between two study groups regarding the complications. Early closure was also not found to be a predictive factor of post-ileostomy closure complications.

CONCLUSION

Early closure (<2 weeks) of ileostomy after LAR in patients with rectal adenocarcinoma is a safe and feasible technique which is associated with favorable outcome.

Determination of Factors Related to the Reversal and Perioperative Outcomes of Defunctioning Ileostomies in Patients Undergoing Rectal Cancer Surgery: A Regression Analysis Model

PURPOSE

Defunctioning ileostomies are often performed during rectal cancer surgery. However, stomas are sometimes associated with complications, while 20-30% of them are never reversed. Additionally, ileostomy closure can have associated morbidity, with rates as high as 45%, with the respective literature evidence being scarce and conflicting. Thus, we evaluated the stoma reversal outcomes and the risk factors for non-closure after rectal cancer surgery.

METHODS

This is a retrospective analysis of a prospectively collected database of all patients who had a defunctioning ileostomy at the time of resection for rectal cancer. All operations were performed by the same surgical team. A multivariable regression model was implemented.

RESULTS

In this study, 129 patients (male: 68.2%, female: 31.8%) were included. Ileostomy formation was associated with a total of 31% complication rate. Eventually 73.6% of the stomas were reversed at a mean time to closure of 26.6 weeks, with a morbidity of 13.7%. Non-reversal of ileostomy was correlated with neoadjuvant CRT (OR: 0.093, 95% CI: 0.012-0.735), anastomotic leakage (OR: 0.107, 95% CI: 0.019-0.610), and lymph node yield (OR: 0.946, 95% CI: 0.897-0.998). Time to reversal was affected by the N status, the LNR, the need for adjuvant chemotherapy, and the histologic grade.

CONCLUSION

In patients with rectal cancer resections, defunctioning stoma closure rate and time to closure were associated with several perioperative and pathological outcomes.

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

Purpose

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

Methods

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

Results

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

Conclusion

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

Continent ileostomies: what the radiologist needs to know

Continent ileostomies are performed in patients who are not candidates for or do not want a traditional J-pouch after total colectomy. In these cases, patients may opt for a type of continent ileostomy instead of an end ileostomy. The most common types of continent ileostomies include the Kock (K) pouch, S-pouch and Barnett Continent Intestinal Reservoir. The normal fluoroscopic and CT appearance of these types of continent ileostomies are reviewed. CT provides better evaluation of the proximal small bowel and pouch for inflammatory bowel disease, while fluoroscopy is superior in evaluating the nipple valve. Common complications of these types of continent ileostomies are discussed including slipped nipple valve, pouch inflammation, fistulas, and polyps. Radiologist should be familiar with the different types of continent ileostomies that exist and their common complications.

Benefits of laparoscopy-assisted ileostomy in colorectal cancer patients with bowel obstruction

BACKGROUND

Ileostomies are commonly performed after colon and rectal surgeries. Laparoscopy-assisted ileostomy with adhesion lysis may have potential benefits over conventional open surgery.

AIM

To compare the outcomes of laparoscopy-assisted and conventional ileostomies.

METHODS

Data from 48 consecutive patients who underwent ileostomy at our institution between May 2021 and May 2022 were retrospectively analyzed. The groups comprised 26 and 22 patients who underwent laparoscopic ileostomy (laparoscopic group) and conventional ileostomy (conventional group), respectively, performed by a single surgeon. Patient demographics, operative characteristics, postoperative outcomes, and 30-d morbidities and mortality rates were analyzed.

RESULTS

The two groups had comparable mean ages, sex distributions, American Society of Anesthesiologists scores, and body mass indices. However, the laparoscopic group showed similar operative time, better visualization for adhesion lysis, and lower visual analog scale scores than the conventional group.

CONCLUSION

Laparoscopy-assisted ileostomy is a safe and efficient method that produces lower visual analog scale scores, better intraoperative visualization for effective adhesion lysis, and similar operative time compared with conventional ileostomy.

open loop ileostomy reversal: a meta-analysis of randomized and non-randomized studies

PURPOSE

The present meta-analysis compares laparoscopic loop ileostomy reversal (LLIR) with open loop ileostomy reversal (OLIR) to evaluate the advantages of the laparoscopic technique compared to the traditional open technique in ileostomy reversal.

METHODS

Primary endpoints were hospital stay and overall complications. Secondary endpoints were operative time, EBL, readmission, medical complications, surgical complications, reoperation, wound infection, anastomotic leak, intestinal obstruction, and cost of the procedures. The included studies were also divided based on the type of anastomotic approach: extracorporeal laparoscopic loop ileostomy reversal (ELLIR) and intracorporeal laparoscopic loop ileostomy reversal (ILLIR).

RESULTS

In the analysis, 4 studies were included. Three hundred fifty-four patients were enrolled. As primary outcomes, a significant difference was found in hospital stay between the LLIR and OLIR groups (MD = -0.67, 95% CI -1.16 to -0.19, P = 0.007). The overall complications outcome resulted in favor of the LLIR group (RR = 0.64, 95% CI 0.43-0.95, P = 0.03). As secondary outcomes, the operative time was in favor of the OLIR group (MD = 19.18, 95% CI 10.20-28.16, P < 0.001). Surgical complications were lower in the LLIR group than in the OLIR group. No other differences between the secondary endpoints were found. Subgroup analysis showed a significant difference in hospital stay between the ILLIR and OLIR groups (MD = -0.92, 95% CI -1.55 to -0.30, P = 0.004). The overall complications outcome significantly favored the ILLIR group (RR = 0.38, 95% CI 0.15-0.96, P = 0.04).

CONCLUSION

Our meta-analysis shows an advantage in terms of shorter post-operative hospitalization and reduction of complications of LLIR compared to OLIR. The sub-group analysis shows that performing an extracorporeal anastomosis exposes the same risks of the open technique.

Dysbiosis of gut microbiota during fecal stream diversion in patients with colorectal cancer

BACKGROUND

The effect of fecal stream diversion on the gut microbiota is still uncertain. The present study was designed to assess the effect of fecal stream diversion on the composition of the gut microbiota in patients with colorectal cancer. We included patients undergoing left-sided colorectal cancer surgery with (ileostomy group) or without (control group) diverting ileostomy. Fecal samples were collected from 10 patients in each group before surgery (t1) and after ileostomy repair in the ileostomy group and 6-12 months after the initial surgery in the control group (t2). The fecal microbiota was assessed using 16S rRNA sequencing, and changes in the composition of the fecal microbiota were compared between the two groups.

RESULTS

Alpha diversity analysis revealed that the complexity of fecal microbiota decreased between t1 and t2 only in the ileostomy group. Beta diversity analysis also showed dissimilarity between t1 and t2 only in the ileostomy group. The composition of the microbiota was similar between the two groups at t1. However, at t2, the ileostomy group had lower proportion of beneficial bacteria (Lachnospiraceae, 3.8% vs. 29.9%, p < 0.001; Ruminococcaceae, 0.6% vs. 18.4%, p < 0.001; Blautia, 0.1% vs. 9.1%, p < 0.001; Faecalibacterium, 0.2% vs. 7.5%, p < 0.001) and a higher proportion of harmful bacteria (Proteobacteria, 17.9% vs. 5.1%, p = 0.006; Clostridium, 16.2% vs. 1.1%, p = 0.013; Streptococcus, 17.7% vs. 1.6%, p = 0.002) than the control group.

CONCLUSIONS

Fecal stream diversion was closely associated with less diversity and dysbiosis of the gut microbiota.

Short- and long-term direct and indirect costs of illness after ostomy creation - a Swedish nationwide registry study

BACKGROUND

Despite advance in care of people with an ostomy, related complications remain prevalent. The objective of this study was to examine short- and long-term healthcare resource utilization and associated costs after ostomy creation.

METHODS

This observational study was based on retrospectively collected data from national and regional Swedish registries. The population consisted of people living in Sweden, who had an ostomy created. The earliest index date was 1 January 2006, and people were followed for ten years, until death, reversal of temporary ostomy, termination of purchases of ostomy products, or end of study, which was 31 December 2019. Each person with an ostomy was matched with two controls from the general population based on age, gender, and region.

RESULTS

In total, 40,988 persons were included: 19,645 with colostomy, 16,408 with ileostomy, and 4,935 with urostomy. The underlying diseases for colostomy and ileostomy creations were primarily bowel cancer, 50.0% and 55.8% respectively, and additionally inflammatory bowel disease for 20.6% of ileostomies. The underlying cause for urostomy creation was mainly bladder cancer (85.0%). In the first year after ostomy creation (excl. index admission), the total mean healthcare cost was 329,200 SEK per person with colostomy, 330,800 SEK for ileostomy, and 254,100 SEK for urostomy (100 SEK was equivalent to 9.58 EUR). Although the annual mean healthcare cost decreased over time, it remained significantly elevated compared to controls, even after 10 years, with hospitalization being the main cost driver. The artificial opening was responsible for 19.3-22.8% of 30-day readmissions after ostomy creation and for 19.7-21.4% of hospitalizations during the entire study period. For the ileostomy group, dehydration was responsible for 13.0% of 30-day readmissions and 4.5% of hospitalization during the study period.

CONCLUSIONS

This study reported a high disease burden for persons with an ostomy. This had a substantial impact on the healthcare cost for at least ten years after ostomy creation. Working ability seemed to be negatively impacted, indicated by increased cost of sickness absence and early retirement. This calls for improved management and support of ostomy care for the benefit of the affected persons and for the cost of society.

Ileostomy versus colostomy: impact on functional outcomes after total mesorectal excision for rectal cancer

AIM

Even if a defunctioning stoma mitigates the serious consequences of anastomotic leakage after total mesorectal excision (TME) for rectal cancer, the presence of a temporary stoma or having a stoma for a prolonged period of time may also be a determining factor for further morbidities and poor bowel function. The aim of this study was to evaluate the impact of diverting stomas on clinical and functional outcomes after TME, comparing ileostomy or colostomy effects.

METHODS

All consecutive patients who underwent TME for rectal cancer between March 2017 and December 2020 in three Italian referral centres were enrolled in the present study. For every patient sex, age, stage of the tumour, neoadjuvant therapy, surgical technique, anastomotic technique, the presence of a diverting stoma, perioperative complications and functional postoperative status were recorded. Considering the diverting stoma, the kind of stoma, length of time before closure and stoma related complications were evaluated.

RESULTS

During the study period 416 consecutive patients (63% men) were included. Preoperative neoadjuvant therapy was performed in 79%. A minimally invasive approach was performed in >95% of patients. Temporary stoma was performed during the operation in 387 patients (93%) (ileostomy 71%, colostomy 21%). The stoma was closed in 84% of patients. The median time from surgery to stoma closure was 145 days. No difference was found between ileostomy and colostomy in overall morbidity after stoma creation and closure. Moreover, increased postoperative functional disturbance seemed to be significantly proportional to the attending time for closure for ileostomy.

CONCLUSION

The presence of a defunctioning stoma seems to have a negative impact on functional bowel activity, especially for delayed closure for ileostomy. This should be considered when the kind of stoma (ileostomy vs. colostomy) is selected for each patient.

Sodium depletion and secondary hyperaldosteronism in outpatients with an ileostomy: a cross-sectional study

OBJECTIVE

Patients with an ileostomy may experience postoperative electrolyte derangement and dehydration but are presumed to stabilise thereafter. We aimed to investigate the prevalence of sodium depletion in stable outpatients with an ileostomy and applied established methods to estimate their fluid status.

METHODS

We invited 178 patients with an ileostomy through a region-wide Quality-of-Life-survey to undergo outpatient evaluation of their sodium and fluid status. The patients delivered urine and blood samples, had bioelectrical impedance analysis performed and answered a questionnaire regarding dietary habits.

RESULTS

Out of 178 invitees, 49 patients with an ileostomy were included; 22 patients (45%, 95% CI, 31-59%) had unmeasurably low urinary sodium excretion (<20 mmol/L), indicative of chronic sodium depletion, and 26% (95% CI, 16-41%) had plasma aldosterone levels above the reference value. Patients with unmeasurably low urinary sodium excretion had low estimated glomerular filtration rates (median 76, IQR 63-89, mL/min/1.73m2) and low venous blood plasma CO2 (median 24, IQR 21-26, mmol/L), indicative of chronic renal impairment and metabolic acidosis. Bioelectrical impedance analysis, plasma osmolality, creatinine and sodium values were not informative in determining sodium status in this population.

CONCLUSION

A high proportion of patients with an ileostomy may be chronically sodium depleted, indicated by absent urinary sodium excretion, secondary hyperaldosteronism and chronic renal impairment, despite normal standard biochemical tests. Sodium depletion may adversely affect longstanding renal function. Future studies should investigate methods to estimate and monitor fluid status and aim to develop treatments to improve sodium depletion and dehydration in patients with an ileostomy.IMPACT AND PRACTICE RELEVANCE STATEMENTSodium depletion in otherwise healthy persons with an ileostomy was identified in a few publications from the 1980s. The magnitude of the problem has not been demonstrated before. The present study quantifies the degree of sodium depletion and secondary hyperaldosteronism in this group, and the results may help guide clinicians to optimise treatment. Sodium depletion is easily assessed with a urine sample, and sequelae may possibly be avoided if sodium depletion is detected early and treated. This could ultimately help increase the quality of life in patients with an ileostomy.

A propensity score matching investigation of short-term results of single-incision laparoscopic low anterior rectal resection via ileostomy site

Aims

The study was performed to verify the results of single-incision laparoscopic surgery (SILS) through the ileostomy site for low rectal cancer compared with conventional laparoscopic surgery (CLS).

Materials and Methods

From January 2019 to November 2021, 133 patients with low rectal cancer underwent single-incision (n = 27) or conventional (n = 106) methods of low anterior rectal resection surgery with ileostomy. All patients were balanced by propensity score matching for basic information in a ratio of 1:2, resulting in 27 and 54 in SILS and CLS groups, respectively.

Results

Relative to the CLS group, the SILS group exhibited fewer leucocyte changes, shorter time to first exhaust and first bowel sounds, shorter length of hospital stay and lower Visual Analogue Score on post-operative days (POD2) and POD3. Intraoperative or post-operative complications or readmissions were comparable between the two groups. The oncologic results remained consistent between the two groups other than the number of lymph nodes dissected in group no. 253.

Conclusions

Single-incision laparoscopic low rectal resection surgery through the ileostomy site has advantages in terms of reduced post-operative pain, shorter post-operative exhaust time and length of hospital stay while also achieving oncologic outcomes similar to those of conventional laparoscopy. It can be an alternative procedure for patients with low rectal cancer who require ileostomy.

Predictors of cognitive impairment in patients undergoing ileostomy for colorectal cancer: a retrospective analysis

Background

Early detection of cognitive impairment in patients undergoing ileostomy for colorectal cancer may help improve patient outcomes and quality of life. Identifying risk factors and clinically accessible factors is crucial for prevention and treatment.

Objective

This retrospective study aimed to identify risk factors for post-operative cognitive impairment in patients undergoing ileostomy for colorectal cancer and to explore potential factors for its prevention and treatment.

Methods

A total of 108 cases were selected and included in the study. Patient data including general characteristics, disease stage, complications, and chemotherapy status were collected, and sleep quality and cognitive function were assessed using questionnaires and follow-up. Patients were randomly divided into training and validation groups. A random forest model was used to rank clinical features based on their contribution to predicting the prognosis of cancer-related cognitive impairment (CRCI). Nomograms were constructed using the support vector machine-recursive feature elimination (SVM-RFE) method, and the minimal root-mean-square error (RMSE) values were compared to select the best model. Regression analysis was performed to determine independent predictors.

Results

Significant differences were observed in age, body mass index (BMI), alcohol consumption, frequency of physical activity, comorbidity, and cancer-related anemia (CRA) between the CRCI and non-CRCI groups. Random forest analysis revealed that age, BMI, exercise intensity, PSQI scores, and history of hypertension were the most significant predictors of outcome. Univariate logistic regression analysis of 18 variables revealed that age, alcohol consumption, exercise intensity, BMI, and comorbidity were significantly associated with the outcome of CRCI (p < 0.05). Univariate and multivariate models with P-values less than 0.1 and 0.2, respectively, showed better predictive performance for CRCI. The results of univariate analysis were plotted on a nomogram to evaluate the risk of developing CRCI after colorectal cancer surgery. The nomogram was found to have good predictive performance. Finally, regression analysis revealed that age, exercise intensity, BMI, comorbidity, and CRA were independent predictors of CRCI.

Conclusions

This retrospective cohort study revealed that age, exercise intensity, BMI, comorbidity, CRA, and mobility are independent predictors of cognitive impairment in patients undergoing ileostomy for colorectal cancer. Identifying these factors and potential factors may have clinical implications in predicting and managing post-operative cognitive impairment in this patient population.

Impact of ileostomy in the adjuvant treatment and outcome of colon cancer

BACKGROUND

After tumor resection, a preventive diverting loop ileostomy creation is a routine surgical procedure to prevent anastomotic leakage and infections and to preclude secondary surgeries. Despite its benefits, several studies have proposed potential complications that extend the disease course by impairing the feasibility of adjuvant chemotherapy and adherence.

PURPOSE

The aim of this study was to evaluate the impact of ileostomy complications on the adherence to adjuvant treatment and overall survival (OS) of colon cancer (CC) patients.

METHODS

Retrospective, observational study. Patients diagnosed with colon adenocarcinoma were treated between January 2010 and December 2020 at the National Cancer Institute in Mexico.

STATISTICAL ANALYSIS

χ² and t-test, Kaplan-Meier, log-rank, and Cox regression. Statistical significance differences were assessed when p was bilaterally < 0.05.

RESULTS

The most frequent complications of loop-derived ileostomy were hydro-electrolytic dehydration (50%), acute kidney injury (AKI) (26%), grade 1-2 diarrhea (28%), and grade 3-4 diarrhea (21%) (p = 0.001). Patients with complete chemotherapy did not reach the median OS. In contrast, the median OS for patients with non-complete chemotherapy was 56 months (p = 0.023). Additionally, 5-year OS reached to 100% in the early restitution group, 85% in the late restitution group, and 60% in the non-restitution group (p = 0.016). Finally, AKI (p = 0.029; 95% confidence interval (CI) 3.348 [1.133-9.895]), complete chemotherapy (p = 0.028; 95% CI 0.376 [0.105-0.940]), and reversed ileostomy (p = 0.001; 95% CI 0.125 [0.038-0.407]) remained as predictors of overall survival for patients with CC treated with a loop ileostomy.

CONCLUSIONS

Our results emphasize the early stoma reversal restitution as a safe and feasible alternative to prevent severe complications related to ileostomies which improve chemotherapy adherence and overall survival of colon cancer patients. This is one of the pioneer studies analyzing the impact of ileostomy on treatment adherence and outcome of Latin American patients with colon cancer.

Does stoma modify compliance with enhanced recovery after surgery programs? Results of a cohort study

PURPOSE

Few studies have focused on enhanced recovery programs (ERPs) in patients who have received a stoma after colorectal surgery. The objective of the study was to compare ERP compliant patients who have not received a stoma, those who received a colostomy, and those who received an ileostomy.

METHODS

This study used data that had been prospectively collected as part of the ERP audit performed through the Groupe francophone de Réhabilitation Améliorée après Chirurgie [Francophone Group for Enhanced Recovery after Surgery] over a 4-year period. All patients who had undergone colorectal surgery were included and separated into three groups (no stoma, ileostomy, and colostomy). The primary outcome was ERP compliance, calculated through the use of 16 tracer items.

RESULTS

Of the 422 recruited patients, 317 had not received a stoma (75.12%), 59 had an ileostomy (13.98%), and 46 had a colostomy (10.90%). ERP compliance was 73% in the non-stoma group, 66.6% in the ileostomy group, and 66% in the colostomy group (p < 0.001). Multivariate analysis showed that patients from the ileostomy group had a higher risk of bowel preparation [OR = 9.1; 95% CI = 1.16-71.65] and of maintaining their urinary catheter [OR = 0.3; 95% CI = 0.14-0.81] than the group which did not receive a stoma. Patients from the colostomy group required significantly more drainage than those in the non-stoma group (OR = 4.3; 95% CI = 1.33-14.02).

CONCLUSION

ERP is feasible in colorectal surgery in the context of stomas, but in case of ileostomy protecting a rectal surgery, the audit system must be adapted to the protocols in use in the departments.

A comparative study of stoma-related complications from diverting loop ileostomy or colostomy after colorectal surgery

PURPOSE

Even though minor, stoma-related complications significantly impact quality of life, they are often excluded from clinical analyses that compare short-term postoperative outcomes of loop ileostomy and loop colostomy. This study compares stoma-related complications between loop ileostomy and loop colostomy after rectal resection, including minor complications, and discusses the characteristics of diverting stoma types.

METHODS

A retrospective review was conducted in patients who underwent diverting stoma construction after rectal resection. Data on patient background and postoperative short-term outcomes, including stoma-related complications and morbidity after stoma closure, were collected and compared between loop ileostomy and loop colostomy groups. Morbidities of all severity grades were targeted for analysis.

RESULTS

A total of 47 patients (27 loop ileostomy, 20 loop colostomy) underwent diverting stoma construction following rectal resection. Overall stoma-related complications, incidence of skin irritation, high-output stoma, and outlet obstruction were significantly higher in the loop ileostomy group but high-output stoma and outlet obstruction were absent in the loop colostomy group. Regarding morbidity after stoma closure, operation times and surgical site infections were significantly higher in the loop colostomy group while anastomotic leakage after diverting stoma closure occurred (2 cases; 15%) in the loop colostomy group but not the loop ileostomy group.

CONCLUSION

Because stoma-related complications were significantly higher in the loop ileostomy group, and even these minor complications may impair QOL, early loop ileostomy closure is recommended. For loop colostomy, stoma-related morbidities are lower but post-closure leakage is a calculated risk.

MUC-FIRE: Study protocol for a randomized multicenter open-label controlled trial to show that MUCous FIstula REfeeding reduces the time from enterostomy closure to full enteral feeds

Background

After enterostomy creation, the distal bowel to the ostomy is excluded from the physiologic passage of stool, nutrient uptake, and growth of this intestinal section. Those infants frequently require long-term parenteral nutrition, continued after enterostomy reversal due to the notable diameter discrepancy of the proximal and distal bowel. Previous studies have shown that mucous fistula refeeding (MFR) results in faster weight gain in infants. The aim of the randomized multicenter open-label controlled MUCous FIstula REfeeding ("MUC-FIRE") trial is to demonstrate that MFR between enterostomy creation and reversal reduces the time to full enteral feeds after enterostomy closure compared to controls, resulting in shorter hospital stay and less adverse effects of parenteral nutrition. Methods/Design: A total of 120 infants will be included in the MUC-FIRE trial. Following enterostomy creation, infants will be randomized to either an intervention or a non-intervention group.In the intervention group, perioperative MFR between enterostomy creation and reversal will be performed. The control group receives standard care without MFR.The primary efficacy endpoint of the study is the time to full enteral feeds. Secondary endpoints include first postoperative bowel movement after stoma reversal, postoperative weight gain, and days of postoperative parenteral nutrition. In addition adverse events will be analyzed.

Discussion

The MUC-FIRE trial will be the first prospective randomized trial to investigate the benefits and disadvantages of MFR in infants. The results of the trial are expected to provide an evidence-based foundation for guidelines in pediatric surgical centers worldwide.

Trial registration

The trial has been registered at clinicaltrials.gov (number: NCT03469609, date of registration: March 19, 2018; last update: January 20, 2023, https://clinicaltrials.gov/ct2/show/NCT03469609?term=NCT03469609&draw=2&rank=1).

Beclometasone inhaler-induced recovery of refractory peri-ileostomy skin complications

Peristomal skin complications (PSCs) are relatively common in ostomy patients, particularly in those with ileostomies. Non-healing irritation presents a clinical challenge and leads to pain and impaired quality of life for patients.

METHODS

The cases of four ileostomy patients experiencing severe, challenging PSCs refractory to appliance changes, conventional dressings and barrier creams are discussed.

FINDINGS

The cases of one male and one female patient with an end ileostomy post-subtotal colectomy for ulcerative colitis, one female with a defunctioning ileostomy post-anterior resection for sigmoid carcinoma and one male with an end ileostomy with a complex Crohn's surgical history are described. Two puffs of a 250 mcg metered dose beclometasone inhaler were applied to the affected skin once or twice daily. Treatment ranged from 6 to 21 days. Complete resolution was seen in all cases.

CONCLUSION

Topical use of a beclometasone inhaler was effective for severe peri-ileostomy PSC secondary to four different aetiologies. Further studies are warranted to determine the effectiveness of this treatment in a larger patient cohort.

Ileostomy volvulus as an underreported problem causing small bowel obstruction in patients living with ostomy: a case report and literature review

Purpose

Ileostomy volvulus is a rare cause of small bowel obstruction. We present an unusual case of ileostomy volvulus without the presence of adhesions. Additionally, a systematic literature review was performed to collate the current literature on the causes, diagnosis, treatment, and preventative measures of ileostomy-related small bowel obstruction.

Methods

PubMed (Medline), Embase, Google Scholar, Scopus, and Cochrane CENTRAL were searched from their inception up to August 2022. This study adhered to the PRISMA guidelines and was registered on PROSPERO. The primary outcomes included patients' demographics, imaging modality, indication for initial surgery, type and configuration of stoma, surgical treatment, and recurrence of volvulus. The quality of included studies was assessed using the Murad tool. Written informed consent was obtained from the patient.

Results

Seven studies were included, comprising 967 patients. Stoma outlet obstruction (SOO) was reported in all 159 patients, and 12 had ileostomy volvulus as the cause. A majority of patients had loop ostomies for ileostomy volvulus. No complications or mortality were reported in the included studies, and half of the included studies were deemed to be of good quality.

Conclusion

This case demonstrates the need for high clinical suspicion of SOO in patients with loop ileostomy, and rapid management should be undertaken. Whilst loop ileostomies, increased rectus abdominal muscle thickness, and lower preoperative total glucocorticoid dosage are associated with SOO, large-scale retrospective studies are needed to validate our findings.

Impact of a diverting ileostomy in total mesorectal excision with primary anastomosis for rectal cancer

BACKGROUND

The role of diverting ileostomy in total mesorectal excision (TME) for rectal cancer with primary anastomosis is debated. The aim of this study is to gain insight in the clinical consequences of a diverting ileostomy, with respect to stoma rate at one year and stoma-related morbidity.

METHODS

Patients undergoing TME with primary anastomosis for rectal cancer between 2015 and 2017 in eleven participating hospitals were included. Retrospectively, two groups were compared: patients with or without diverting ileostomy construction during primary surgery. Primary endpoint was stoma rate at one year. Secondary endpoints were severity and rate of anastomotic leakage, overall morbidity rate within thirty days and stoma (reversal) related morbidity.

RESULTS

In 353 out of 595 patients (59.3%) a diverting ileostomy was constructed during primary surgery. Stoma rate at one year was 9.9% in the non-ileostomy group and 18.7% in the ileostomy group (p = 0.003). After correction for confounders, multivariate analysis showed that the construction of a diverting ileostomy during primary surgery was an independent risk factor for stoma at one year (OR 2.563 (95%CI 1.424-4.611), p = 0.002). Anastomotic leakage rate was 17.8% in the non-ileostomy group and 17.2% in the ileostomy group (p = 0.913). Overall 30-days morbidity rate was 37.6% in the non-ileostomy group and 56.1% in the ileostomy group (p < 0.001). Stoma reversal related morbidity rate was 17.9%.

CONCLUSIONS

The stoma rate at one year was higher in patients with ileostomy construction during primary surgery. The incidence and severity of anastomotic leakage were not reduced by construction of an ileostomy. The morbidity related to the presence and reversal of a diverting ileostomy was substantial.

Outcomes according to treatment modalities as a bridge to curative surgery for malignant obstruction of the proximal colon: stent versus stoma

BACKGROUND/AIMS

The optimal treatment for acute malignant obstruction of the proximal colon (MOPC, proximal to the splenic flexure) remains challenging. Emergency resection, the traditional modality for MOPC, has shown significantly high mortality and morbidity rates, according to recent studies. This study aimed to investigate the clinical outcomes of stent vs stoma as a bridge to curative surgery for MOPC.

METHODS

This retrospective cohort study included 72 patients who underwent endoscopic placement of a self-expanding metallic stent (SEMS) or loop ileostomy for MOPC at six referral centers between January 2011 and July 2021. Clinical and pathological characteristics, procedure-related complications, and long-term mortality rates after curative surgery were analyzed.

RESULTS

During a mean follow-up period of 32 months, 30 patients (41.7%) underwent ileostomy preferentially for more proximal cancer, complete obstruction, and advanced tumor stage compared to the SEMS group. No difference was found in procedure-related complications, but five deaths were observed after ileostomy. Survival analysis for 5-year mortality after curative surgery showed no significant difference between the bridge modalities (log-rank p = 0.253).

CONCLUSION

In this study, SEMS as a bridge to surgery showed relatively safe results in terms of post-procedural mortality. However, these results should be considered when performing ileostomy in patients with more advanced malignant obstruction.

Assessment of risk factors and establishment of a nomogram model to predict early high-output ileostomy

OBJECTIVE

This study evaluated the prevalence and perioperative risk factors for early high-output ileostomy (EHOI) and developed a precise nomogram model to predict the occurrence of EHOI.

METHODS

140 patients who underwent ileostomy surgery at three hospitals in Wuhan, Hubei Province, between January 2022 and May 2022 were enrolled in this prospective cohort study. By using univariate and multifactorial logistic regression, independent risk variables for the development of EHOI were examined, and the nomogram model for predicting the risk of EHOI was created by using R software. The calibration curve and area under the receiver operating characteristic curve (ROC AUC) were used to evaluate the calibration and discrimination of the prediction model, Hosmer-Lemeshow to verify the fit of the model. Clinical impact curve (CIC) and decision curve analysis (DCA) were used to assess the model's clinical efficacy.

RESULTS

A total of 132 patients participated in the study, and the incidence of EHOI was 25.8% (34/132). The nomogram model incorporated 3 risk factors hypertension, drinking habits, and high white blood cell (WBC) count after surgery. The AUC was 0.742, and the nomogram showed great calibration and clinical validity by comparing the calibration curve, DCA, and CIC.

CONCLUSIONS

Hypertension, drinking, and high WBC was significantly correlated with EHOI. The nomogram model has great clinical value in predicting the EHOI.

Late parastomal evisceration: A case report of a rare complication following loop ileostomy for an obstructing rectal cancer

INTRODUCTION AND IMPORTANCE

Parastomal evisceration is a very uncommon complication of a stoma, with only a few cases currently published in the literature. It may occur either early or late following either ileostomy or colostomy and has been reported in both the emergency and elective setting. The aetiology is likely multifactorial, but a few risk factors have been identified that predispose to its occurrence. Early recognition and prompt surgical evaluation is necessary, and management depends on patient, pathologic and environmental factors.

CASE PRESENTATION

A 50-year-old man with an obstructing rectal cancer underwent elective surgery for the creation of a temporary loop ileostomy prior to commencement of neoadjuvant chemotherapy (capecitabine and oxaliplatin). His background included obesity, alcohol excess and he was a current smoker. His postoperative course was complicated by a non-obstructing parastomal hernia which was managed non-operatively in the context of his neoadjuvant therapy. Seven months after his loop ileostomy and three days post his sixth cycle of chemotherapy, he presented to the emergency department with signs of shock and evisceration of small bowel via a dehiscence of the mucocutaneous junction at the superior aspect of the loop ileostomy. We discuss this unusual case of late parastomal evisceration.

CLINICAL DISCUSSION

Parastomal evisceration is caused by a mucocutaneous dehiscence. Risk factors such as coughing, increased intra-abdominal pressure, emergency surgery, and stomal prolapse or hernia can all be predisposing factors.

CONCLUSION

Parastomal evisceration is a life-threatening complication that requires urgent assessment, resuscitation, and early referral to the surgical team for intervention.

Efficacy of gel containing organic extra virgin olive oil for peristomal skin hygiene: A pilot randomised controlled trial

AIM

To assess the efficacy and safety of the application, during stoma hygiene, of a pH-neutral gel containing organic EVOO (oEVOO) for the maintenance of peristomal skin integrity.

METHOD

Patients with a colostomy or ileostomy were enrolled in a pilot randomized controlled trial and assigned treatment with a pH-neutral gel made from natural products including oEVOO or usual stoma hygiene gel. The primary outcome was three domains of abnormal peristomal skin: Discolouration, Erosion and Tissue overgrowth. Secondary outcomes that were evaluated included skin moisture; oiliness; skin elasticity; water-oil balance; patients' perceptions; difficulty inserting and removing the pouching system; pain, any other chemical, infectious, mechanical, or immunological complications of concern. The intervention lasted 8 weeks.

RESULTS

Twenty-one patients were recruited for the trial and randomly assigned to either the experimental group (n = 12) or the control group (n = 9). The groups did not differ significantly in terms of patient characteristics. No significant differences between groups were identified either at baseline (p = 0.203) or at the end of the intervention (p = 0.397). In the experimental group, domains of abnormal peristomal skin improved after the intervention. The difference observed before and after the intervention was statistically significant (p = 0.031).

CONCLUSION

The use of a gel containing oEVOO has shown similar levels of efficacy and safety to other gels commonly used for peristomal skin hygiene. It is also relevant to highlight that a significant improvement in skin condition was observed in the experimental group before and after the intervention.

The role of stomas in the initial and long-term management of Hirschsprung disease

AIM

To review the role of stomas in the initial and long-term management of Hirschsprung disease (HD).

METHODS

Patients treated for HD at our institution between January 2004 and August 2021 were identified. Data were collected regarding: demographics, indication/bowel location/type of stomas performed and outcomes, pull-through (PT) procedure, and follow-up duration.

RESULTS

Ninety-five patients (78 male) were identified including one early unrelated death. Forty-four of 94 (47%) required a stoma before PT procedure. Of these 44, 38 (86%) had ileostomies and the remaining six (14%) colostomies; one ileostomy remains long-term. The commonest indication for initial stomas was washout failure (41%). Ninety-one patients had undergone primary PT or secondary PT with stoma closure at the time of the study. A further new stoma was required after primary PT or three-stage management in 20/91 (22%). The commonest indications were constipation/soiling (25%) and anastomotic leak (20%). Seven out of 20 (35%) were performed within 30 days of a previous procedure and all were closed; three patients required further long-term stomas. Thirteen (65%) required a stoma >30 days, nine remain long-term. Surgical revision of stomas was required in 14/56 (25%) - prolapse and retraction being the commonest indications. Overall, 56/94 (60%) patients required stomas (pre- and/or post-PT) to manage their condition and 13/94 (14%) have a long-term stoma in place. Mean follow-up was 7.8 years (0.5 - 17.6).

CONCLUSIONS

Stomas remain an integral part of HD management both initially (47%) and long-term (14%); they carry a considerable associated morbidity. Ileostomy is preferred for initial management.

A novel nomogram to predict low anterior resection syndrome (LARS) after ileostomy reversal for rectal cancer patients

BACKGROUND AND AIM

Low anterior resection syndrome (LARS) in patients undergoing low or ultra-low anterior resection (LAR) is a common problem and significantly impacts the quality of life. Patients with an ileostomy after LAR are more likely to develop LARS. However, there hasn't been a model predicting LARS occurrence in these patients. This study aims to construct a nomogram to predict the probability of LARS occurrence in patients with temporary ileostomy and guide preventive strategies before reversal.

METHODS

168 patients undergoing LAR with ileostomy from one center were enrolled as the training cohort, and 134 patients of the same inclusion criteria from another center were enrolled as the validation cohort. The training cohort was screened for risk factors for major LARS using univariate and multivariate logistic regression. The nomogram was constructed using the filtered variables, the ROC curve was used to describe the model's discrimination, and the calibration was used to describe the accuracy.

RESULTS

The optimal cut-off value for stoma closure time was 128 days. Three risk factors were identified using logistic regression analysis: preoperative radiotherapy (OR = 3.038, [95%CI 1.75-5.015], P = 0.005), stoma closure time (OR = 2.298, [95%CI 1.088-4.858], P = 0.029) and pN stage (OR = 1.739, [95%CI 1.235-3.980], P = 0.001). A nomogram was constructed based on these three variables and showed good performance predicting major LARS after stoma reversal. The area under the curve (AUC) was 0.827 in the training group and 0.821 in the validation group; The calibration curve suggested good precision in both groups.

CONCLUSIONS

This novel nomogram can accurately predict the probability of major LARS occurrence after ileostomy reversal for rectal cancer patients. This model can help screen ileostomy patients with high risks and guide individualized preventive strategies before stoma reversal.

Protective loop ileostomy or colostomy? a risk evaluation of all common complications

Purpose

Protective ileostomy and colostomy are performed in patients undergoing low anterior resection with a high leakage risk. We aimed to compare surgical, medical, and daily care complications between these 2 ostomies in order to make individual choice.

Methods

Patients who underwent low anterior resection for rectal tumors with protective stomas between January 2011 and September 2018 were enrolled. Stoma-related complications were prospectively recorded by wound, ostomy, and continence nurses. The cancer stage and treatment data were obtained from the Taiwan Cancer Database of our Big Data Center. Other demographic data were collected retrospectively from medical notes. The complications after stoma creation and after the stoma reversal were compared.

Results

There were 176 patients with protective colostomy and 234 with protective ileostomy. Protective ileostomy had higher proportions of high output from the stoma for 2 consecutive days than protective colostomy (11.1% vs. 0%, P<0.001). Protective colostomy resulted in more stoma retraction than protective ileostomy (21.6% vs. 9.4%, P=0.001). Female sex, open operation, ileostomy, and carrying stoma more than 4 months were also significantly associated with a higher risk of stoma-related complications during diversion. The incidence of complication after stoma reversal did not differ between colostomy group and ileostomy group (24.3% vs. 20.9%, P=0.542).

Conclusion

We suggest avoiding colostomy in patients who are female and potential prolong diversion when stoma retraction is a concern. Otherwise, ileostomy should be avoided for patients with impaired renal function. Wise selection and flexibility are more important than using one type of stoma routinely.

Small-bowel plication prevents ileostomy prolapse in young children with inflammatory bowel disease

PURPOSE

Young children with medically refractory very early-onset inflammatory bowel disease (VEO-IBD) sometimes benefit from ileostomy diversion alone or may be offered subtotal colectomy with ileostomy. Though generally well-tolerated, ileostomy complications are frequent. Prolapse is particularly frustrating as it can be difficult and painful to reduce, becomes a recurring problem is some patients, and often requires ostomy revision or bowel resection.

METHODS

Over the course of the past 6 months, eight consecutive children with VEO-IBD underwent 10 creation or revision of a diverting ileostomy (two underwent subsequent colectomy with ileostomy revision). In each of these 10 cases, we plicated the ileum just proximal to the ileostomy for a distance of approximately 3 cm using a running permanent monofilament suture.

RESULTS

No patient who underwent plication of bowel has developed ileostomy prolapse. There were no cases of ileostomy retraction, parastomal hernia or ostomy-level obstruction. One patient required a lysis of a single band adhesion for a more proximal small bowel obstruction. The stomas have functioned well and there have been no complications.

CONCLUSION

Simple bowel plication appears to be a quick and effective way to prevent ileostomy prolapse in young children with VEO-IBD with an ileostomy who are at high risk for prolapse.

Rectal stimulation with prebiotics and probiotics before ileostomy reversal: a study protocol for a randomized controlled trial

BACKGROUND

Ileostomy closure is associated with a high rate of postoperative morbidity, and adynamic ileus is the most common complication, with an incidence of up to 32%. This complication is associated with delayed initiation of oral diet intake, abdominal distention, prolonged hospital stay, and more significant patient discomfort. The present study aims to evaluate the rectal stimulus with prebiotics and probiotics before ileostomy reversal.

METHODS

This is a protocol study for an open-label randomized controlled clinical trial. Ethical approval was received (CAAE: 56551722.6.0000.0071). The following criteria will be used for inclusion: adult patients with rectal cancer stages cT3/4Nx or cTxN+ that underwent loop protection ileostomy, patients treated with neoadjuvant chemoradiotherapy, and patients who underwent laparoscopic or robotic total mesorectal excision. Patients will be randomized to one of two groups. The intervention group (with rectal stimulus): the patients will apply 500 ml of saline solution with 6 g of Simbioflora® rectally, once a day, for 15 days before ileostomy closure. The control group (without rectal stimulation): the patients will close the ileostomy with no previous rectal stimulus. The primary outcomes will be the adynamic ileus (need for postoperative nasogastric tube insertion; nausea/vomiting; or intolerance to oral feedings within the first 72 h) and intestinal transit (time to first evacuation/flatus).

RESULTS

The patient's enrollment starts in January 2023. We expect to finish in July 2025.

DISCUSSION

The findings of this randomized clinical study may have important implications for managing patients undergoing ileostomy reversal.

A rare presentation of appendicitis contained within an incisional hernia post loop ileostomy reversal - A case report

INTRODUCTION AND IMPORTANCE

Appendicitis within an incisional hernia is rare, with current literature describing a small number of cases, occurring through a variety of surgical incisions. We describe a case of appendicitis contained within an incisional hernia following reversal of a loop ileostomy, on a background of previous sigmoid cancer resection. This is the second such case we were able to identify on literature review.

CASE PRESENTATION

A 45 year old man presented with one day of migratory abdominal pain, predominantly focused at a tender, irreducible lump in his right lower quadrant, underlying the scar from previous reversal of loop ileostomy. CT on admission revealed an incisional hernia, containing an inflamed appendiceal tip. He underwent an uncomplicated laparoscopic appendicectomy and primary suture closure of the hernia defect, and was discharged the following day. Acute appendicitis was confirmed on histopathology.

DISCUSSION

Placement of a defunctioning ileostomy is common in the management of colonic cancers, and incisional hernias are a common complication. It is however rare for an appendix to be contained within a hernia sac, and even rarer for appendicitis to develop in this setting. As a result, the presentation of this condition may mimic that of an incarcerated or strangulated incisional hernia, with pre-operative diagnosis typically relying on diagnostic imaging.

CONCLUSION

Incisional hernia appendicitis is rare and presents a diagnostic challenge. Early recognition of this dual pathology is necessary to allow for prompt surgical management of both the appendicitis and hernia, as well as guiding the approach for hernia repair.

Clinical and surgical factors for successful stoma reversal in patients with Crohn's disease-results of a retrospective cohort study

PURPOSE

Despite the wide range of medical and interventional therapy options available, some patients with Crohn's disease (CD) need an ileostomy or colostomy. The aim of this study was to identify clinical, surgical and drug-related predictors of successful stoma reversal in CD patients.

METHODS

A retrospective medical record analysis of surgical department logs, hospital discharge letters and patient reports from outpatient departments was performed for all CD patients who underwent a first ostomy surgery.

RESULTS

Our study analysed a total of 149 patients (76 women, 73 men, median age at first stoma of 34 years after a median CD duration of 9 years), with a median follow-up of 78.4 (IQR 88.6) months after first ostomy surgery. Of these patients, 73 (49%) underwent stoma reversal after a median of 11.7 months (IQR 15.7 months) of whom 17 (23.3%) needed a second stoma. In multivariant analysis, Montreal A1 classification (HR 2.07; 95% confidence interval 1.23-3.47; p = 0.006), a primary laparotomy (HR 2.30; 95% confidence interval 1.20-4.41; p = 0.012) and the absence of perianal/rectal CD activity (HR 3.00; 95% confidence interval 1.86-4.86; p < 0.001) emerged as independent predictors of a shorter time to stoma reversal. Introduction or switch of biological therapy after first stoma was not associated with successful reversal of the stoma (OR 4.6 95% confidence interval 1.45-14.66; p = 0.01). Laboratory parameters had no influence.

CONCLUSION

Clinical and surgical features-rather than medication or laboratory findings-were found to be predictors of successful stoma reversal in CD patients. Future studies focusing on the definition of a Standard Operation Procedure for emergency and elective CD surgery are warranted.

Morbidity of Temporary Loop Ileostomy in Patients with Colorectal Cancer

Leakage of low colorectal anastomoses after total mesorectal excision is a dreaded complication. Hence, an ileostomy is commonly performed during anterior resection especially in patients who have received neoadjuvant radiation. The aim of this study was to quantify the temporary loop ileostomy-related benefits as well as morbidity in patients with colorectal cancer. We did a retrospective study including all patients who underwent anterior resection with diversion ileostomy for biopsy-proven rectal carcinoma at our institute from 1 Jan 2016 to 31 Dec 2017 with follow-up of 2 years. A total of 104 patients were included in the study. In our series, 6.7% patients had an anastomotic dehiscence which precluded patients from stoma reversal. 12.5% of the patients had a stoma-related complication. 5.7% patients had complications following a stoma reversal. Eighty percent of the patients who developed clinically evident dehiscence in the immediate postoperative period were managed conservatively because of the presence of stoma. We did not have any mortality related to the stoma. 18.3% patients did not have their stomas reversed. The stoma non-reversal due to anastomotic dehiscence or stricture could be attributed to in 7.7% patients. 3.8% had to have their ileostomies converted to a permanent colostomy due to either a rectovaginal fistula or dehiscence or stricture. The complications associated with ileostomy are not insignificant. In our study, the tumor location in lower rectum was the only significant factor for non-reversal. We have to objectively identify patients who are at low risk for leakage and avoid ileostomy in them, and also try to minimize the morbidity of ileostomy by methods like early closure.
