Exigent ileostomy hemorrhage. A complication of proctocolectomy in patients with chronic ulcerative colitis and primary sclerosing cholangitis

Case Series Regarding Parastomal Variceal Bleeding: Presentation and Management

Parastomal variceal bleeding (PVB) is a serious complication occurring in up to 27% of patients with an ostomy and concurrent cirrhosis and portal hypertension. The management of PVB is difficult and there are no clear guidelines on this matter. Transjugular intrahepatic portosystemic shunt (TIPS), sclerotherapy, and /or coil embolization are all therapies that have been shown to successfully manage PVB. We present a case series with five different patients who had a PVB at our institution. The aim of this case series is to report our experience on the management of this infrequently reported but serious condition. We also conducted a systemic literature review focusing on the treatment modalities of 163 patients with parastomal variceal bleeds. In our series, patient 1 had embolization and sclerotherapy without control of bleed and expired on the day of intervention due to hemorrhagic shock. Patient 2 had TIPS in conjunction with embolization and sclerotherapy and had no instance of rebleed 441 days after therapy. Patient 3 did not undergo any intervention due to high risk for morbidity and mortality, the bleed self-resolved and there was no further rebleed, this same patient died of sepsis 73 days later. Patient 4 had embolization and sclerotherapy and had no instance of rebleed 290 days after therapy. Patient 5 had TIPS procedure and was discharged five days post procedure without rebleed, patient has since been lost to follow-up.

Proctocolectomy-ileal pouch-anal anastomosis for ulcerative colitis after liver transplantation for primary sclerosing cholangitis: a multi-institutional analysis

BACKGROUND

The association between primary sclerosing cholangitis (PSC) and ulcerative colitis (UC) often mandates their contemporaneous management. Orthotopic liver transplantation (OLTX) has emerged as the only curative therapy for PSC, and total proctocolectomy with ileal pouch-anal anastomosis (IPAA) is the definitive treatment for refractory UC. The published experience to date describing IPAA after OLTX has been limited; we sought to examine outcomes associated with proctocolectomy-IPAA after OLTX.

MATERIALS AND METHODS

We reviewed our multi-institutional experience performing proctocolectomy-IPAA for UC after OLTX for PSC.

RESULTS

Twenty-two patients underwent proctocolectomy-IPAA for UC after OLTX for PSC at four academic medical centers between 1989 and 2006. No perioperative complications or allograft dysfunction were observed. During a median follow-up of 52 months, complications have included transient dehydration (n = 6), chronic pouchitis (n = 2), recurrent PSC (n = 2), small bowel obstruction (n = 2), and pouch-anal anastomotic stricture (n = 1). Median 24-h stool frequency was 5, and fecal continence was reported as satisfactory by all patients.

CONCLUSIONS

This multi-institutional experience suggests that proctocolectomy-IPAA can be performed safely after OLTX. Management strategies should include optimization of small bowel length during pouch and ileostomy construction, vigorous postoperative hydration, early ileostomy closure, and careful monitoring for pouchitis.

Bleeding stomal varices: case series and systematic review of the literature

BACKGROUND & AIMS

Bleeding stomal varices are a common problem in patients with surgical stomas and portal hypertension, and remain difficult to diagnose and manage.

METHODS

We identified all patients at our institution with bleeding stomal varices from 1989 to 2004. We surveyed all patients undergoing ileal pouch-anal anastomosis from 1997 to 2007 for bleeding anastomotic varices. Finally, we performed a systematic review of the literature focusing on diagnosis and treatment of bleeding stomal varices that included 74 English language studies of 234 patients.

RESULTS

We identified 8 patients with bleeding stomal varices. Recognition of stomal varices typically was delayed, particularly when failing to examine the ostomy without the appliance. Stomal variceal bleeding was confirmed by Doppler ultrasound or angiographic imaging. Simple local therapy usually stopped bleeding, albeit temporarily. Sclerotherapy was effective, but at the expense of unacceptable stomal damage. Decompressive therapy was required for secondary prophylaxis, including transjugular intravascular transhepatic shunts (2 patients), surgical portosystemic shunts (2 patients), and liver transplantation (1 patient). No patient with an ileal pouch-anal anastomosis developed anastomotic bleeding from varices.

CONCLUSIONS

Primary prevention of bleeding stomal varices requires avoidance of creating enterocutaneous stomas in patients with portal hypertension. Careful inspection of the uncovered ostomy is essential for bleeding stomal varices diagnosis. Once identified, conservative measures will stop bleeding temporarily with definitive therapy required, including transjugular intravascular transhepatic shunts, surgical shunts, or liver transplantation.

Transjugular intrahepatic porto-systemic shunt and variceal embolisation in the management of bleeding stomal varices

BACKGROUND AND AIMS

Bleeding from stomal varices is uncommon. Local measures to control the bleeding offer short-lived control. Our experience with transjugular intrahepatic porto-systemic shunt (TIPS) and variceal embolisation is presented and appraised.

PATIENT AND METHODS

Three patients presented with bleeding from stomal varices (Child-Pugh class B, n=2 and class C, n=1) in association with primary sclerosing cholangitis, autoimmune hepatitis and alcoholic liver disease. Local treatment measures including suture ligation, sclerotherapy and re-siting of the stoma achieved short-lived control. TIPS were inserted in all 3 patients, with embolisation of the stomal varices in 2.

RESULTS/FINDINGS

The radiological interventions were uncomplicated and resulted in cessation of the bleeding in all patients. One of the patients has had no further bleeding at 12 months' follow-up post-TIPS insertion. The other two patients re-bled at 5 and 6 months post-TIPS insertion and were successfully managed by insertion of a second TIPS in one patient and by balloon dilatation of the TIPS in another. The former patient has had no re-bleeding at a further 8 months' follow-up, while the latter had re-bleeding at 12 months post-TIPS insertion and underwent liver transplantation.

INTERPRETATION/CONCLUSION

Transjugular intrahepatic porto-systemic shunt with variceal embolisation offers an effective, minimally invasive management option in patients with bleeding stomal varices, and may be used as the primary mode of intervention in conjunction with medical therapy, and as the definitive therapy in patients unfit for surgery. TIPS and variceal embolisation do not preclude subsequent liver transplantation, and may be used during the acute situation as a bridge to transplantation.

Complications of abdominal stoma surgery

PURPOSE

This study was undertaken to review and summarize the complications of ileostomy and colostomy creation and subsequent closure.

METHODS

The English-language medical literature for at least the past 15 years was reviewed comprehensively.

RESULTS

Complications of surgery for the creation of end, loop, and "end loop" stomas are presented. Technical factors, which might influence complication rates, are discussed. Optimal management of ostomy complications is presented, especially for peristomal hernias. Similarly, techniques and complications for stoma closure are analyzed.

CONCLUSIONS

Stoma creation is not a trivial undertaking; careful surgical technique minimizes complications (which are relatively frequent), and promotes good ostomy function. Peristomal hernias are difficult to cure permanently. The morbidity of ileostomy and colostomy closure is also appreciable.

Clinical features in primary sclerosing cholangitis

This article describes clinical features in primary sclerosing cholangitis, including clinical presentation and complications. The natural history of the disease is discussed, as well as the strong association to inflammatory bowel disease.

Percutaneous transhepatic embolization as treatment for bleeding ileostomy varices

We report two patients with bleeding stomal varices following total colectomy and ileostomy. The varices were demonstrated by superior mesenteric angiography and percutaneous transhepatic mesenteric venography; dilated ileal veins drained via the stomal varices into abdominal wall veins. Bleeding from the stomal varices was treated by transhepatic embolization. The first patient required three transhepatic embolizations after recurrent bleeding due to recanalization of the embolized ileal vein and the development of collaterals from the adjacent ileal veins over a one-year period. The second patient died of respiratory failure 1 week after embolization. Neither patient developed mesenteric or stomal ischemia.

Bleeding from peristomal varices: perspectives on prevention and treatment

Peristomal variceal bleeding is a serious complication in patients with chronic liver disease undergoing colon surgery with a stoma. Our aim was to examine the morbidity of bleeding for peristomal, perianastomotic, and esophageal varices in a group of patients with chronic liver disease who underwent colectomy at the Mayo Clinic between 1970 and 1988. Morbidity was evaluated in terms of the number of major bleeding episodes and the number of units of blood transfused. The treatment of bleeding was also evaluated. One hundred seventeen patients (74 males and 43 females) aged 11-78 years were studied. Sixty-two patients (53 percent) had a permanent stoma, while 55 patients (47 percent) had a colonic resection and anastomosis. Sixty-seven patients (62 percent) had chronic ulcerative colitis and primary sclerosing cholangitis. In the stoma group, bleeding appeared from stomal and/or esophageal varices in 19 patients (31 percent), while, in the non-stoma group, bleeding exclusively from the esophageal varices occurred in eight patients (15 percent). Perianastomotic variceal bleeding was never observed. The 5-year cumulative probabilities of one major bleed occurring from gastrointestinal varices appeared to be similar between the two groups. Patients who bled from peristomal varices with or without esophageal bleeding (n = 17) rebled more frequently (6.5 +/- 5.5 vs. 3 +/- 1.6; P less than 0.05) and were transfused more often (14.9 +/- 12.3 vs. 7.5 +/- 4.1; P less than 0.05) than patients who bled exclusively from esophageal varices (n = 10). No difference was found in the incidence of recurrent bleeding and the number of units of blood transfused between patients who bled exclusively from peristomal varices (n = 10) and those who bled from both peristomal and esophageal varices (n = 7). Medical and local measures were more effective in controlling esophageal bleeding than in controlling peristomal bleeding. Therefore, patients with chronic liver disease who must undergo colectomy should have a distal anastomosis rather than a terminal stoma.

The role of endoscopic injection sclerotherapy in the management of bleeding peristomal varices

Peristomal varices usually occur in patients with enterostomies who develop portal hypertension, and represent a cause of recurrent or intractable gastrointestinal bleeding. Treatment options for such bleeding include surgical ligation of varices, stoma revision with devascularization, injection sclerotherapy, portacaval shunt, or liver transplantation. We reviewed the records of seven patients with peristomal varices, who were followed for a mean of 17 months after diagnosis. Fourteen episodes of clinically significant peristomal bleeding occurred in six patients. Surgical ligation of varices was ineffective in controlling bleeding in two of three patients, although stoma revision with devascularization was temporarily effective in two other patients. Injection sclerotherapy, used in three patients, effectively controlled acute bleeding without serious complications or need for surgery. Definitive treatment for peristomal bleeding (portacaval shunt or liver transplantation) has prevented any further bleeding in three patients for a mean of 8 months after surgery.

Treatment of bleeding stomal varices. Report of a case and review of the literature

Variceal bleeding from ileostomy, colostomy, or ileal conduit stomas is unusual. There is no consensus on which of the various treatment options is best. A case of bleeding ileostomy varices is presented. The English-language medical literature since 1962 is reviewed and an additional 71 cases of stomal variceal bleeding are identified. Treatment options evaluated include stomal manipulation, variceal ligation, sclerotherapy, beta blockade, and surgical shunting. The incidence of rebleeding, requirement for additional procedures, and survival with the various options are compared. Although stomal manipulation was the most commonly performed procedure, portosystemic shunting had the lowest incidence of both rebleeding and need for additional procedures (4 percent each) and provided the longest mean postoperative survival (50 months). The authors conclude that portosystemic shunting is the treatment of choice in patients with bleeding from stomal varices who are good surgical candidates.

Indications and outcome of reoperation for ileostomy complications in inflammatory bowel disease

Indications for ileostomy revision in 49 patients with inflammatory bowel disease operated upon between January 1975 and December 1984 were obstruction (15), retraction (10), parastomal hernia (9), prolapse (8), and fistula (4). Recurrent Crohn's disease was an important factor in the pathogenesis of ileostomy complications particularly obstruction, retraction and fistula. Local revision without laparotomy was successful in seven of eight patients with an ileostomy prolapse, but in only four of eight patients with a retracted stoma. Results of local repair without laparotomy and resiting were successful in five of six patients with a parastomal hernia. Laparotomy was usually necessary in patients with obstruction especially if there was underlying Crohn's disease and in patients with peristomal fistula. Resiting of the stoma after laparotomy was used only if the stoma site was outside the rectus muscle or if the original stoma site was infected.
