Anastomotic Leak after Ileal Pouch-Anal Anastomosis

Management of J-pouch Complications

Most patients with a restorative proctocolectomy with ileal pouch-anal anastomosis do well; however, properly identifying acute and chronic complications are paramount to managing and correcting these complications to allow for optimal pouch function and avoid pouch failure. Inflammatory conditions like pouchitis may require ongoing medical therapy, but surgical intervention may be needed to correct any underlying septic complication and to repair any structural disorders. Patients with signs of pouch failure may be candidates for pouch augmentation or redo pouch surgery and should be referred to high-volume centers before pouch excision is offered if the patient wishes to avoid a permanent ileostomy.

Diagnosis and treatment of primary ileal pouch leaks: a 27-year experience at a referral center

BACKGROUND

Ileal pouch-anal anastomosis (IPAA) is considered the preferred restorative surgical procedure for patients with ulcerative colitis and familial adenomatous polyposis requiring proctocolectomy. Unfortunately, postoperative leaks remain a complication with potentially significant ramifications. This study aimed to provide a comprehensive description of the evaluation, management, and outcomes of leaks after primary IPAA procedures.

METHODS

Between 1995 and 2022, a total of 4058 primary IPAA procedures were performed at Cleveland Clinic. From a prospectively maintained pouch registry, we retrospectively reviewed the data of 237 patients who presented to the pouch center for management. Of these, 114 (3%) had undergone the index IPAA procedure at our clinic (de novo cases), whereas 123 patients had their index IPAA performed elsewhere. Data were missing for 43 patients, resulting in a final cohort of 194 patients.

RESULTS

Our cohort had an average age of 41 years (range, 16-76) at the time of leak diagnosis. Overall, 55.2% were males, average body mass index was 24.4 kg/m2, and pain was the most prevalent presenting symptom (61.8%), followed by fever (34%). Leaks were confirmed through diagnostic testing in 141 cases, whereas 27.3% were detected intraoperatively. The most common initial diagnoses were pelvic abscess (47.4%) and enteric fistulas (26.8%), including cutaneous (9.8%), vaginal (7.2%), and bladder fistulas (3.1%). By location, leaks occurred at the tip of the "J" (52.6%), at the pouch-anal anastomotic site (35%), and in the body of the pouch (12.4%). A nonoperative management approach was initially attempted in 49.5% of cases, including antibiotic therapy, drainage, endoclip, and endo-sponge, with a success rate of 18.5%. Surgery was eventually required in 81.4% of patients, including (1) sutured or stapled pouch repair (52.5%), with diversion performed in 87.9% of these cases either before or during the salvage surgery; (2) pouch excision with neo-IPAA (22.7%), including 9 patients from the first group; and (3) pouch disconnection, repair, and reanastomosis (9.3%). Pouch failure occurred in 8.4%, with either pouch excision (11.1%) or permanent diversion (4.5%). Ultimately, 12.4% of patients (24 of 194) required permanent diversion, with all necessitating pouch excision. In the 30-day follow-up after salvage surgery, short-term complications arose in 38.7% of patients. The most common complications observed were ileus, pelvic abscess/sepsis, and fever.

CONCLUSION

Leaks after primary IPAA procedures represent an infrequent, yet challenging, complication. Despite attempts at nonoperative management, the success rate is limited. Salvage surgery is associated with a high pouch retention rate, underscoring its importance in the management of post-IPAA leaks.

Complications following ileal pouch-anal anastomosis in pediatric ulcerative colitis

Ileal pouch-anal anastomosis (IPAA) is the procedure of choice for reconstruction after total proctocolectomy in pediatric patients with ulcerative colitis. 30-60 % of patients undergoing IPAA will experience a postoperative complication. The primary objective of this article is to address the most common complications specific to IPAA in the pediatric population and provide an up-to-date review of their presentation, risk factors, workup, and management. We also share our preferred approaches to management and prevention of complications, where relevant. We intend to provide a concise review on the topic aimed at pediatric surgeons and healthcare providers involved in the care of this population with the goal of contributing to improved outcomes and patient quality of life.

Creation of a Custom Endoluminal Vacuum-Assisted Device for Salvage of Ileal Pouch-Anal Anastomotic Leak

Endoluminal vacuum-assisted devices have become increasingly popular solutions for low-colorectal injuries and anastomotic defects in recent years. We present a case of a 23-year-old male who underwent salvage of an ileal pouch-anal anastomosis (IPAA) anastomotic leak with a customized endoluminal vacuum sponge and cavity marsupialization. This case highlights the easy-to-follow steps to create a customized endoluminal vacuum (endo-vac) sponge with readily available materials for the treatment of low colorectal anastomotic leaks. Included are step-by-step photos and instructions for successful endoluminal vacuum device construction.

Assessment of the ileoanal pouch for the colorectal surgeon

INTRODUCTION

Many pouch complications following ileoanal pouch surgery have an inflammatory or mechanical nature, and specialist colorectal surgeons are required to assess the anatomy of the ileoanal pouch in multiple settings. In this study, we report our stepwise clinical and endoscopic assessment of the patient with an ileoanal pouch.

METHODS

The most common configuration of the ileoanal pouch is a J-pouch, and the stapled anastomosis is more frequently performed than a handsewn post-mucosectomy. A structured clinical and endoscopic assessment of the ileoanal pouch must provide information on 7 critical areas: anus and perineum, rectal cuff, pouch anal anastomosis, pouch body, blind end of the pouch, pouch inlet and pre-pouch ileum.

RESULTS

We have developed a structured pro forma for step-wise assessment of the ileoanal pouch, according to 7 essential areas to be evaluated, biopsied and reported. The structured assessment of the ileoanal pouch in 102 patients allowed reporting of abnormal findings in 63 (61.7%). Strictures were diagnosed in 27 patients (26.4%), 3 pouch inlet strictures, 21 pouch anal anastomosis strictures, and 3 pre-pouch ileum strictures. Chronic, recurrent pouchitis was diagnosed in 9 patients, whilst 1 patient had Crohn's disease of the pouch.

CONCLUSIONS

Detailed clinical history, assessment of symptoms and multidisciplinary input are all essential for the care of patients with an ileoanal pouch. We present a comprehensive reporting pro forma for initial clinical assessment of the patient with an ileoanal pouch, with the aim to guide further investigations and inform multidisciplinary decision-making.

Redo ileal pouch-anal anastomosis for early versus late sepsis-related pouch failure

BACKGROUND

Pouch failure after restorative proctocolectomy with ileal pouch-anal anastomosis occurs in 5% to 15% of cases, mostly due to septic complications. We aimed to determine if the timing of pouch failure impacted long-term outcomes for redo ileal pouch-anal anastomosis after sepsis-related complications.

METHOD

We retrospectively analyzed our prospectively collected institutional pouch database. Patients who underwent redo ileal pouch-anal anastomosis for septic complications between 1988 and 2020 were divided into an early (pouch failure within 6 months of stoma closure after index operation, or stoma never closed) and a late failure group (pouch failure after 6 months of stoma closure). The primary endpoint was pouch survival.

RESULTS

In total, 335 patients were included: 241 (72%) in the early and 94 (28%) in the late failure group. The most common indication for failure was an anastomotic leak in the early failure group (163, 68%) and fistula in the late failure group (59, 63%), P < .001. Pouch survival at 3, 5, and 10 years was 77%, 75%, and 72% for the early and 79%, 75%, and 68% for the late failure group (P = .94). The most common reason for redo pouch failure was fistula in both groups. Quality of life was similar in both groups. In multivariate analysis, the only factor associated with pouch failure was the final diagnosis of Crohn's disease.

CONCLUSION

Outcomes after redo ileal pouch-anal anastomosis were comparable between patients with early and late sepsis-related index pouch failure, with acceptable rates of long-term pouch survival and good quality of life.

MRI of the ileal pouch

Ileal pouch surgery is the surgical gold standard treatment for patients with ulcerative colitis (UC) and familial adenomatous polyposis (FAP). However, ileal pouch surgery is a technically challenging procedure and is associated with high morbidity. Clinical presentations of pouch complications are often nonspecific but imaging can identify many of these complications and is essential in clinical management. This paper will focus on magnetic resonance imaging (MRI) of the ileal pouch, including recommended MRI protocol and approach to imaging interpretation with an emphasis on those ileal pouch complications particularly well evaluated with MRI.

Intraoperative crystalloid-colloid infusion ratio associated with the development of early surgical complications after ileal pouch-anal anastomosis in ulcerative colitis: a multicenter long-term follow-up study

BACKGROUND

Intraoperative intravenous fluid administration proves to be associated with surgical patients' postoperative outcomes. Few studies reported the relationship between intraoperative crystalloid-colloid infusion ratio and early surgical complications after ileal pouch-anal anastomosis (IPAA) in ulcerative colitis (UC).

METHODS

Data on patients with underwent IPAA from January 2008 to March 2022 at our three inflammatory bowel disease (IBD) surgery centers were retrospectively collected. Intraoperative anesthetic data were recorded and later evaluated by our team anesthesiologist.

RESULTS

A total of 140 eligible patients with a median follow-up time of 6.0 years [interquartile range (IQR): 2.0-8.0] were enrolled. Among all enrolled patients, 34 (24.3%) developed early surgical complications after IPAA. Greater blood loss and lower crystalloid-colloid infusion ratio were observed in patients with early surgical complications. Crystalloid-colloid infusion ratio < 2 and blood loss ≥ 200 ml had the most significant area under the receiver-operating characteristic curve (AUC) of 0.664 and 0.674 in predicting early surgical complications. Crystalloid-colloid infusion ratio < 2 [odds ratio (OR), 2.571; 95% confidence intervals (CI), 1.067-6.195, p = 0.035] and blood loss ≥ 200 ml (OR, 3.165; 95% CI, 1.288-7.777, p = 0.012) were independent risk factors for the development of early post-IPAA complications.

CONCLUSION

Intraoperative crystalloid-colloid infusion ratio < 2 and blood loss volume over 200 ml during IPAA contribute to the occurrence of early surgical complications. Early attentions and necessary interventions are warranted to avoid these risk factors during the IPAA surgery in order to prevent the development of early surgical complications.
