Ulcerative colitis-related severe enteritis: an infrequent but serious complication after colectomy

Effectiveness of probiotic- and fish oil-loaded water-in-oil-in-water (W1/O/W2) emulsions at alleviating ulcerative colitis

Ulcerative colitis (UC) is a common chronic inflammatory disease that causes serious harm to human health. Probiotics have the effect of improving UC. This study evaluated the preventative potential of water-in-oil-in-water (W1/O/W2) emulsions containing both probiotics and fish oil on UC and associated anxiety-like behavior using a mice model. UC model was established in mice by administering dextran sulfate sodium salt (DSS). Free probiotics, probiotic-loaded emulsions, or fish oil and probiotic co-loaded emulsions were then orally administered to the mice. Various bioassays, histological studies, 16s rDNA gene sequencing, and behavioral experiments were conducted to assess changes in the intestinal environment, microbiota, and anxiety-like behavior of the mice. The fish oil and probiotic co-loaded emulsions significantly reduced the inflammatory response by enhancing tight junction protein secretion (ZO-1, Occludin, and Claudin-1), inhibiting pro-inflammatory factors (TNF-α, and IL-1β), and promoting short-chain fatty acids (SCFAs) production. These emulsions also modified the gut microbiota by promoting beneficial bacteria and suppressing pathogenic bacteria, thereby restoring a balanced gut microbiota. Notably, the emulsions containing both probiotics and fish oil also ameliorated anxiety-like behavior in the mice. The co-delivery of probiotics and fish oil using W1/O/W2 emulsions has shown significant promise in relieving UC and its associated anxiety-like behavior. These findings provide novel insights into the development of advanced therapeutic strategies for treating UC.

Severe Disease Activity May Predispose Patients to Post-colectomy Duodenitis Associated with Ulcerative Colitis

Objective Diffuse mucosal inflammation in the duodenum, distinct from peptic ulcer disease, has been repeatedly reported in patients with ulcerative colitis (UC). The pathogenesis of this complication remains uncertain; however, colectomy for medically refractory UC appears to trigger duodenitis. Cases in which colectomy was performed for UC were analyzed to characterize UC-related duodenitis after colectomy. Methods A retrospective case-control study of UC-related duodenitis that developed after colectomy in medically refractory UC between January 2011 and June 2020 was conducted. UC-related duodenitis was diagnosed based on typical clinical, endoscopic, and histological findings, and no duodenitis was endoscopically defined by the normal duodenal mucosa. Clinical and laboratory data, disease severity, and medications used were collected and compared between the UC-related and non-duodenitis cases. Results Ten UC-related duodenitis and 35 non-duodenitis cases were identified among 45 patients with UC who underwent esophagogastroduodenoscopy after colectomy. Disease severity, defined by the C-reactive protein level and partial Mayo score prior to colectomy, was significantly higher in duodenitis patients than in non-duodenitis patients. In comparison to non-duodenitis patients, duodenitis patients more frequently received rescue therapies with calcineurin inhibitors or anti-tumor necrosis factor (TNF)-α agents at the time of colectomy (100% vs. 65.7%). Conclusion Patients with UC with higher disease activity, especially those who require rescue therapies with calcineurin inhibitors and anti-TNF-α agents, may be prone to developing UC-related duodenitis after colectomy.

Case report: Successful treatment of ulcerative colitis-related post-colectomy enteritis refractory to multiple therapies with ustekinumab

Ulcerative colitis-related severe post-colectomy enteritis is a rare condition. A few cases have undergone successful treatment with corticosteroids, Cyclosporine, Azathioprine, and Infliximab. We aim to evaluate the treatment outcome of ustekinumab in this rare case. Here we describe a 56-year-old woman with post-colectomy enteritis refractory to multiple therapies. Finally, the patient was administered with ustekinumab treatment. Under monitoring, the feces volume of the patient decreased from 5000-7000 mL per day to 1700-2000 mL. Over a one-year follow-up period, the patient gradually gained body weight, with the stoma drainage of formed brown stool. And the villi of the small intestinal mucosa restore growth. To our knowledge, this is the first report that indicates ustekinumab could be a treatment selection for ulcerative colitis-related severe post-colectomy enteritis.

Surgical Treatment in Ulcerative Colitis, Still Topical: A Narrative Review

In this paper, different studies were integrated to conclude the impact of ulcerative colitis (UC) on the patient's vital prognosis, specifically highlighting the association with colorectal cancer (CRC). These severe complications have led us to consider studying the role of preventive surgery in managing UC. This study reviewed total preventive colectomy in UC patients for preventing the onset of CRC, the role of surgery in UC management, and its potential as a definitive treatment for the condition. The study also emphasized the effectiveness of annual colonoscopic monitoring and preventive colectomy in reducing the incidence of colorectal cancer (CRC). It discussed the role of laparoscopic surgery in minimizing postoperative complications and highlighted that partial surgical resection of the colon can be a viable option, offering improved bowel function without increasing the risk of CRC-related mortality. Elective surgery has an important place in UC management by preventing the development of forms requiring emergency surgery. Although surgery can cure UC, it can lead to significant postoperative complications and adverse effects.

A case of ulcerative colitis-related postoperative enteritis treated with granulocyte and monocyte apheresis

A 46-year-old man, receiving continuous steroid therapy for refractory ulcerative colitis with an insufficient response to anti-tumor necrosis factor-α therapy, presented with left buttock pain. He was diagnosed with steroidal left femoral head necrosis, and total proctocolectomy with permanent ileostomy was performed. At 6 months postoperatively, the patient developed general fatigue, abdominal pain, and severe ileostomy diarrhea. Computed tomography revealed continuous intestinal edema from the descending duodenal leg to the upper jejunum. Gastrointestinal endoscopy revealed deep ulcers, coarse mucosa, and duodenal erosion. Based on clinical progress, findings, and pathology, the patient was diagnosed with ulcerative colitis-related postoperative enteritis. Although 5-aminosalicylic acid treatment was initiated, his symptoms persisted, bloody diarrhea from colostomy was observed. Subsequently, granulocyte and monocyte apheresis treatment was added. Symptoms and endoscopic findings improved with granulocyte and monocyte apheresis. Azathioprine was introduced as maintenance therapy, and no sign of recurrence was observed. Although ulcerative colitis-related postoperative enteritis has no definitive treatment, granulocyte and monocyte apheresis may be considered for initial treatment.

Syndrome of inappropriate secretion of antidiuretic hormone after total proctocolectomy for ulcerative colitis

We report a case of the syndrome of inappropriate secretion of antidiuretic hormone (SIADH) after total proctocolectomy followed with ileal pouch-anal anastomosis (TPC-IPAA) for ulcerative colitis (UC). The patient was a 46-year-old woman. She was diagnosed with UC of pancolitis in 2000. High grade dysplasia was detected in the transverse colon after a surveillance colonoscopy in 2021. She underwent laparoscopy-assisted TPC-IPAA. On the sixth postoperative day, she had a decreased level of consciousness that worsened on the following day. Her laboratory data showed a serum sodium level of 108 mEq/L and the plasma osmolality was 234 mOsm/kg. We did not find any other abnormalities in the laboratory examination that could cause hyponatremia. Computed tomography scan showed no central nervous system disturbances such as a pituitary tumor, antidiuretic hormone-producing tumors, or pulmonary diseases. The patient was diagnosed with Syndrome of inappropriate secretion of antidiuretic hormone (SIADH) caused by surgical invasion. We started to administer 3% sodium chloride slowly to improve the hyponatremia. Her serum sodium level became normal and stable. Although it is rare for SIADH to be caused by abdominal surgery, if hyponatremia is observed after surgery, the possibility of postoperative SIADH should be considered.

Postcolectomy Enteritis in a Pediatric Patient With Ulcerative Colitis

Postcolectomy enteritis is characterized by diffuse small bowel inflammatory changes following colectomy for medically refractory ulcerative colitis. Symptoms may include abdominal pain, massive intestinal bleeding, intestinal perforation, and high stoma output. While the exact pathogenesis is unknown, immune dysregulation with increased cytokine and inflammatory cell response is suspected to lead to the inflammatory response. Therefore, immunosuppressive medications are the mainstay for treatment. All cases to date have been described in adult patients. We present a case of postcolectomy enteritis in a pediatric patient who improved without significant intervention.

Treatment of pouchitis, Crohn's disease, cuffitis, and other inflammatory disorders of the pouch: consensus guidelines from the International Ileal Pouch Consortium

Pouchitis, Crohn's disease of the pouch, cuffitis, polyps, and extraintestinal manifestations of inflammatory bowel disease are common inflammatory disorders of the ileal pouch. Acute pouchitis is treated with oral antibiotics and chronic pouchitis often requires anti-inflammatory therapy, including the use of biologics. Aetiological factors for secondary pouchitis should be evaluated and managed accordingly. Crohn's disease of the pouch is usually treated with biologics and its stricturing and fistulising complications can be treated with endoscopy or surgery. The underlying cause of cuffitis determines treatment strategies. Endoscopic polypectomy is recommended for large, symptomatic inflammatory polyps and polyps in the cuff. The management principles of extraintestinal manifestations of inflammatory bowel disease in patients with pouches are similar to those in patients without pouches.

Diagnosis and classification of ileal pouch disorders: consensus guidelines from the International Ileal Pouch Consortium

Restorative proctocolectomy with ileal pouch-anal anastomosis is an option for most patients with ulcerative colitis or familial adenomatous polyposis who require colectomy. Although the construction of an ileal pouch substantially improves patients' health-related quality of life, the surgery is, directly or indirectly, associated with various structural, inflammatory, and functional adverse sequelae. Furthermore, the surgical procedure does not completely abolish the risk for neoplasia. Patients with ileal pouches often present with extraintestinal, systemic inflammatory conditions. The International Ileal Pouch Consortium was established to create this consensus document on the diagnosis and classification of ileal pouch disorders using available evidence and the panellists' expertise. In a given individual, the condition of the pouch can change over time. Therefore, close monitoring of the activity and progression of the disease is essential to make accurate modifications in the diagnosis and classification in a timely manner.

Ulcerative colitis-related postoperative enteritis treated with anti-tumor necrosis factor therapy: two case reports and a literature review

Several case reports have described severe postoperative enteritis shortly after total colectomy for ulcerative colitis. The very low incidence of this condition makes diagnosis and treatment difficult, and the appropriate treatment strategy is unclear. We report two cases of enteritis after surgery for ulcerative colitis, which were treated with anti-tumor necrosis factor-α therapy. Case 1 involved a 22-year-old man with symptoms, such as nausea 40 days after total colectomy. Gastrointestinal endoscopy revealed patchy obliteration of the vascular pattern, erosions in the duodenum, and superficial ulcers in the small intestine. His symptoms and endoscopic findings immediately improved upon administration of infliximab; clinical remission lasted 5 years with continuous administration. Case 2 involved a 64-year-old man, who had a large amount of watery diarrhea from ileostomy that increased 5 days after total colectomy; gastrointestinal endoscopy revealed extensive ulcers in the small intestine. Symptoms and endoscopic findings improved with prednisolone, but relapsed with tapering of the corticosteroid. Administration of adalimumab resulted in marked improvement of enteritis. However, the small intestine developed a pinhole stricture, and partial resection of the small intestine was performed. Our experience with two cases indicates that anti-tumor necrosis factor-α therapy may play an important role in ulcerative colitis-related postoperative enteritis.
