Diverting Ostomy: For Whom, When, What, Where, and Why

Pregnancy With a Stoma is Feasible, Though Associated With Manageable Complications

BACKGROUND

Inflammatory bowel disease (IBD) is often diagnosed in young adults, and therefore frequently coincides with pregnancy. Patients may require surgery that includes (temporary) stoma placement. Literature on the occurrence of stoma-complications during pregnancy and the effect on pregnancy outcomes is limited. To evaluate stoma- complications peri- and postpartum, a retrospective study was performed in women who were pregnant while having a stoma.

METHODS

This multicentre cohort and survey study included all pregnant patients with IBD and a stoma who delivered between 2016 and 2023 from 5 Dutch university hospitals. Stoma-complications and pregnancy outcomes were retrospectively collected from electronic patient files. A questionnaire assessed patient-reported complications and long-term stoma-related complaints.

RESULTS

In total, 50 patients were included (median age at conception 31.0 years; 55.2% Crohn's disease and 44.8% ulcerative colitis), comprising 67 pregnancies, 5 of which ended in pregnancy loss. Stoma complications occurred in 44 full-term pregnancies (71.0%), most commonly obstruction (35.5%) and decreased output (29.0%). Surgery was required in four pregnancies due to obstruction (n = 3) and prolapse (n = 2). In the first-year postpartum, 7 patients required surgery for stoma-complications. Amongst 29 women who completed the questionnaire, 10 (34.5%) reported unresolved complications 6 months postpartum. Cesarean sections were performed in 31 (50.0%) pregnancies. Adverse pregnancy outcomes included prematurity (n = 9, 14.5%), low birth weight (n = 9, 14.5%), and dysmaturity (n = 5, 8.1%).

CONCLUSIONS

Pregnancy with a stoma is feasible, though manageable complications often occur. Counseling before pregnancy and close monitoring of symptoms during pregnancy and postpartum are essential for women with IBD and a stoma.

Perianal Crohn's disease: Still more questions than answers

In this editorial we comment on the article by Pacheco et al published in a recent issue of the World Journal of Gastroenterology. We focus specifically on the burden of illness associated with perianal fistulizing Crohn's disease (PFCD) and the diagnostic and therapeutic challenges in the management of this condition. Evolving evidence has shifted the diagnostic framework for PFCD from anatomical classification systems, to one that is more nuanced and patient-focused to drive ongoing decision making. This editorial aims to reflect on these aspects to help clinicians face the challenge of PFCD in day-to-day clinical practice.

Complications associated with loop ileostomy reversal delayed greater than twelve months

Diverting loop ileostomy is performed after colectomy to allow for anastomotic healing, and prevention of pelvic sepsis when an anastomotic leak occurs. There is no consensus on the optimal timing of ileostomy closure, and there is limited data on complications associated with ileostomy closure greater than 12 months after creation. The aim of this study is to investigate outcomes of delayed loop ileostomy closure greater than 12 months after creation. Patients undergoing loop ileostomy closure between 2013 and 2023 at Carilion Medical Center, in Roanoke, VA were reviewed. Cohorts compared were defined as Control Group (closure < 4 months) and Delayed Group (closure > 12 months). Demographics and outcomes were compared. Statistical comparisons were performed using either Wilcoxon rank sum test, Pearson's Chi-squared test or Fisher's exact test. Statistical modeling included binary logistic regression for 30-day readmissions and a generalized linear modeling for days till bowel function returns. Adjusted odds ratios, confidence intervals, and p-values were calculated. There were 135 patients in the Control Group and 19 patients in the Delayed Group. Demographics were similar between the groups except for a higher percentage of patients with diabetes, renal failure and history of cancer in Delayed Group (all p < 0.05). Operative time was longer for Delayed loop ileostomy closure (p < 0.05). Patients in the Delayed Group demonstrated a higher hospital readmission rate within 30 days (p < 0.05). Both groups had similar return of bowel function on post-operative day 2, similar length of stay, and similar rates of postoperative ileus (p = NS). Delayed loop ileostomy closure more than 12 months after creation does not delay return of bowel function but may lead to higher hospital readmission rates within 30 days.

Perianal Fistulizing Crohn's Disease: Utilizing the TOpClass Classification in Clinical Practice to Provide Targeted Individualized Care

BACKGROUND & AIMS

Perianal fistulation is a challenging phenotype of Crohn's disease, with significant impact on quality of life. Historically, fistulae have been classified anatomically in relation to the sphincter complex, and management guidelines have been generalized, with lack of attention to the clinical heterogenicity seen. The recent 'TOpClass classification system' for perianal fistulizing Crohn's disease (PFCD) addresses this issue, and classifies patients into defined groups, which provide a focus for fistula management that aligns with disease characteristics and patient goals. In this article, we discuss the clinical applicability of the TOpClass model and provide direction on its use in clinical practice.

METHODS

An international group of perianal clinicians participated in an expert consensus to define how the TOpClass system can be incorporated into real-life practice. This included gastroenterologists, inflammatory bowel disease surgeons, and radiologists specialized in PFCD. The process was informed by the multi-disciplinary team management of 8 high-volume fistula centres in North America, Europe, and Australia.

RESULTS

The process produced position statements to accompany the classification system and guide PFCD management. The statements range from the management of patients with quiescent perianal disease to those with severe PFCD requiring diverting-ostomy and/or proctectomy. The optimization of medical therapies, as well as the use of surgery, in fistula closure and symptom management is explored across each classification group.

CONCLUSION

This article provides an overview of the system's use in clinical practice. It aims to enable clinicians to have a pragmatic and patient goal-centered approach to medical and surgical management options for individual patients with PFCD.

[Quality of life of ostomates in Germany]

BACKGROUND

The presence of an ostomy may have a serious impact on the quality of life (QoL). The aim of this study was to evaluate the QoL of ostomates in Germany.

METHOD

An online survey was performed using the validated Gastrointestinal Quality of Life Index (GIQLI) by Eypasch et al. Ostomates ≥ 18 yrs. with an ostomy duration ≥ 3 months were eligible to participate.

RESULTS

Completed questionnaires from 519 participants (79.3 % female) with a median age of 50 yrs. (range 19-83 yrs.) and a median ostomy duration of 3 yrs. (range 3 months-58 yrs.) were analyzed. The most common indications for an ostomy were Crohn's disease (36.5 %), colorectal cancer (19.8 %) and ulcerative colitis (18.2 %). The mean GIQLI-Score in the study population was 94.8 ± 24.6, with higher scores corresponding with better QoL and healthy individuals reach 125.8. Limitations were recorded with regard to sleep, tiredness, energy level, endurance, fitness and sexuality. Individuals with a stoma due to Colitis (103,0 ± 24,5), colorectal cancer (99,2 ± 21,7) and Crohn's (95,0 ± 22,8) had the highest mean GIQLI-scores amongst all ostomates.

DISCUSSION

The findings of this study confirm that ostomates have a reduced QoL compared to the healthy population. Amongst all ostomates, those with colitis, colorectal cancer and Crohn's have a better QoL compared to ostomy carriers with other diagnoses.

Proximal protective diverting ostomy following colon anastomosis for penetrating trauma may not be protective: A matched cohort study

INTRODUCTION

Despite the shift toward liberal primary anastomosis in penetrating colon injuries, some surgeons recommend a protective diverting ostomy (DO) proximal to the anastomosis. This study evaluates the effect of DO on outcomes in patients undergoing colon resection and anastomosis following penetrating trauma.

METHODS

The TQIP database (2013-2018) was queried for penetrating colon injuries undergoing colectomy and anastomosis. Patients receiving DO were propensity matched to patients without diverting ostomy (woDO) (1:3). Outcomes were compared between groups.

RESULTS

After matching, 89 DO patients were analyzed. The DO group had more surgical site infections (32 ​% vs. 21 ​%; p ​< ​0.05) and longer hospital stay (20 [13-27] vs. 15 [9-25]; p ​< ​0.05) compared to the woDO group. Mortality and unplanned operations were similar between groups.

CONCLUSIONS

Diverting ostomy after colon resection and anastomosis is associated with increased infectious complications without decreasing unplanned operations or mortality. Its routine role in penetrating colon trauma needs reassessment.

What affects the selection of diverting ileostomy in rectal cancer surgery: a single-center retrospective study

BACKGROUND

The selection of diverting ileostomy (DI) is controversial. This study aimed to explore the factors affecting the selection of diverting ileostomy (DI) following laparoscopic low anterior resection for rectal cancer.

METHODS

This retrospective, case-control study included patients who underwent laparoscopic-assisted sphincter-saving surgery for mid-low rectal cancer from January 2019 to June 2021. Univariate and multivariate analyses were performed on the patient's clinicopathological characteristics and pelvic dimensions measured by abdominopelvic electron beam computed tomography.

RESULTS

A total of 382 patients were included in the analysis, of which 182 patients (47.6%) did not undergo DI, and 200 patients (52.4%) underwent DI. The univariate analysis suggested that male sex (p = 0.003), preoperative radiotherapy (p < 0.001), patients with an anastomosis below the levator ani plane (p < 0.001), the intertuberous distance (p < 0.001), the sacrococcygeal distance (p = 0.025), the mid pelvis anteroposterior diameter (p = 0.009), and the interspinous distance (p < 0.001) were associated with performing DI. Multivariate analysis confirmed that preoperative radiotherapy (p = 0.037, odds ratio [OR] = 2.98, 95% confidence interval [CI] = 1.07-8.30), anastomosis below the levator ani plane (p < 0.001, OR = 7.09, 95% CI = 4.13-12.18), and the interspinous distance (p = 0.047, OR = 0.97, 95% CI = 0.93-1.00) were independently associated with performing DI.

CONCLUSION

Pelvic parameters also influence the choice of DI. According to this single-center experience, patients with a shorter interspinous distance, particularly narrow pelvic with an interspinous distance of < 94.8 mm, preoperative radiotherapy, and anastomosis below the levator ani plane, prefer to have a DI and should be adequately prepared by the physician.

Short-Term Outcomes in Patients Undergoing Virtual/Ghost Ileostomy or Defunctioning Ileostomy after Anterior Resection of the Rectum: A Meta-Analysis

BACKGROUND AND OBJECTIVES

Anterior rectal resection (ARR) represents one of the most frequently performed methods in colorectal surgery, mainly carried out for rectal cancer (RC) treatment. Defunctioning ileostomy (DI) has long been chosen as a method to "protect" colorectal or coloanal anastomosis after ARR. However, DI does not rule out risks of more or less serious complications. A proximal intra-abdominal closed-loop ileostomy, the so-called virtual/ghost ileostomy (VI/GI), could limit the number of DIs and the associated morbidity.

MATERIALS AND METHODS

We performed a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes (PRISMA) guidelines. Meta-analysis was performed by use of RevMan [Computer program] Version 5.4.

RESULTS

The five included comparative studies (VI/GI or DI) covering an approximately 20-year study period (2008-2021). All included studies were observational ones and originated from European countries. Meta-analysis indicated VI/GI as significantly associated with lower short-term morbidity rates related to VI/GI or DI after primary surgery (RR: 0.21, 95% CI: 0.07-0.64, p = 0.006), fewer dehydration (RR: 0.17, 95% CI: 0.04-0.75, p = 0.02) and ileus episodes after primary surgery (RR: 0.20, 95% CI: 0.05-0.77, p = 0.02), fewer readmissions after primary surgery (RR: 0.17, 95% CI: 0.07-0.43, p = 0.0002) and readmissions after primary surgery plus stoma closure surgery (RR: 0.14, 95% CI: 0.06-0.30, p < 0.00001) than the DI group. On the contrary, no differences were identified in terms of AL after primary surgery, short-term morbidity after primary surgery, major complications (CD ≥ III) after primary surgery and length of hospital stay after primary surgery. Conclusions: Given the significant biases among meta-analyzed studies (small overall sample size and the small number of events analyzed, in particular), our results require careful interpretation. Further randomized, possibly multi-center trials may be of paramount importance in confirming our results.

Crohn's Disease-Related Stoma Complications and Their Impact on Postsurgical Course

INTRODUCTION

Crohn's disease (CD) is a chronic inflammatory disease of the gastrointestinal tract. The diversion through a colostomy or an ileostomy is sometimes required for disease control. In these patients, common stoma-related complications sum up with CD-related complications and often require revisional surgery.

METHODS

The aim of the study was to assess stoma morbidity after surgery for CD and to identify the burden of CD-related or CD-associated complications. Thus, details of past medical history, surgery, and follow-up of 54 consecutive patients operated on for CD with any sort of stoma were retrieved from the stoma therapist prospectively maintained database.

RESULTS

In our series, 23 patients had a colostomy, and 31 patients had an ileostomy. Complications occurred after stoma creation in 38 patients (70%) at a median of 1.3 months (interquartile range 0.6-7.2). CD-related complications arose in 8 patients (including pyoderma gangrenosum in 3 patients, peristomal fistulae in 2, granulomas in 2, and peristomal abscess in 1). Patients with CD-related complications tended to have a shorter disease duration (p = 0.07) and higher occurrence of CD-related complications was associated with end-stoma (p = 0.006). In this cohort, 11 cases had to be surgically treated for peristomal fistulae or abscess, parastomal hernia, prolapse, pyoderma gangrenosum, and recurrent CD.

DISCUSSION/CONCLUSIONS

In patients with CD, stoma creation is burdened by a high rate of postoperative complication and a relevant rate is specifically related to CD. Often these patients are required to be reoperated on to redo the stoma. Moreover, end-stoma configuration and aggressive CD phenotype are associated to a higher rate of complications.

OUP accepted manuscript

Cases of delayed colo-anal anastomosis (DCAA) are currently reported instead of the colo-anal anastomosis with a protective loop ileostomy for rectal cancer. Post-operative colonic ischemia is considered as one of the serious complications of colorectal resection. Although indication of DCAA should be carefully selected, we experienced a case of post-operative stenosis caused by colonic ischemia after low anterior resection for rectal cancer, followed by this procedure.

Low preoperative maximum squeezing pressure evaluated by anorectal manometry is a risk factor for non-reversal of diverting stoma

PURPOSE

A diverting stoma is created to prevent anastomotic leakage and related complications impairing sphincteric function in rectal surgery. However, diverting stoma may be left unclosed. This study is aimed to analyze preoperative factors including anorectal manometric data associated with diverting stoma non-reversal before rectal surgery. We also addressed complications related to diverting stoma in patients undergoing surgery for rectal malignant tumor.

METHODS

A total of 203 patients with rectal malignant tumor who underwent sphincter-preserving surgery with diverting stoma were retrospectively evaluated. The risk factors for non-reversal of diverting stoma were identified by univariate and multivariate analyses. For these analyses, anorectal manometric data were measured before rectal surgery. The association between stoma-related complications and other clinicopathological features was also analyzed.

RESULTS

During the median follow-up of 46.4 months, 24% (49 patients) did not undergo stoma reversal. Among parameters that were available before rectal surgery, age ≥ 75 years, albumin < 3.5 g/dl, tumor size ≥ 30 mm, tumor distance from the anal verge < 4 cm, and maximum squeezing pressure (MSP) < 130 mmHg measured by anorectal manometry (ARM) were independent factors associated with stoma non-reversal. The most common stoma-related complication was peristomal skin irritation (25%). Ileostomy was the only factor associated with peristomal skin irritation.

CONCLUSION

The current study demonstrated that low preoperative MSP evaluated by ARM, old age, hypoalbuminemia, and a large tumor close to the anus were predictive of diverting stoma non-reversal. Stoma site should be well deliberated when patients have the aforementioned risk factors for diverting stoma non-reversal.

A case of simultaneous abdominal wall reconstruction and creation of diverting ostomy in a ventral hernia with loss of domain

•

Two problems of non-healing sacral ulcer and an incarcerated ventral hernia.

•

Creation of diverting ostomy and incarcerated ventral hernia repair in one.

•

The patient achieved a good outcome.

•

Wound healing improved and hernia did not recur.

Introduction

Diverting ostomies are traditionally used as a bridge to primary resection in patients with an obstructing mass, or severe inflammatory bowel disease [1]. In some cases, severe infections or non-healing wounds can be better managed after the diversion of fecal material away from the area [2]. In this case report, we discuss a patient who underwent a diverting loop colostomy placement through a ventral hernia defect with primary repair of the hernia in one procedure.

Presentation of case

A 67-year-old female presented with a large, stage four sacral decubitus ulcer and an incarcerated ventral hernia. She was taken to the operating room for a transverse loop diverting colostomy through a large, pre-existing ventral hernia. The ostomy site was passed through the ventral defect at the midline. The remainder of the ventral hernia was closed primarily, and the initial incision was stapled closed. At post-operative day 11, the ostomy remained functional and intact, with no hernia recurrence, and significantly improved healing of the ulcer was seen.

Discussion

The large ventral hernia presented a significant obstacle during pre-operative planning. It was decided that a midline stoma was to be created simultaneously with an abdominal wall reconstruction, as any other site to bring up the ostomy would have been too far laterally.

Conclusion

The patient was discharged in stable condition. This case presents a novel and viable method for the creation of an ostomy in patients with large ventral hernias. Further study regarding long-term outcomes may be beneficial in establishing utility.
