Medical management of ulcerative colitis and indications for colectomy

Good long-term survival and patient-reported outcomes after high tibial osteotomy for medial compartment osteoarthritis

The lateral closing and medial opening wedge high tibial osteotomy can correct a varus malalignment of the knee caused by medial compartment osteoarthritis. These procedures have produced great short-term and mid-term results. As no systematic review has examined their long-term results yet, the goal of this article was to compare the results of all articles about lateral closing and medial opening wedge high tibial osteotomies, published after the year 2000, with a mean follow-up of more than 10 years. A systematic search of the Medline, Web of Science and Cochrane databases resulted in the inclusion of 30 articles. All these studies combined examined the results of 7087 high tibial osteotomies in a total of 6636 patients after a mean follow-up of more than 10 years. Primary outcome measures were the survival rate of the osteotomy, functional scores, patient satisfaction and pain scores. Secondary outcome measures were alignment correction and the identification of factors influencing the survival of the osteotomy. The 5-year, 10-year, 15-year and 20-year survival rates, respectively, ranged from 86 to 100%, 64-97.6%, 44-93.2% and 46-85.1%. The subjective scoring systems showed an improvement postoperatively that was maintained until final follow-up. The anatomical and mechanical tibiofemoral axis were, respectively, corrected to a mean of 7.3°-13.8° of valgus and 0.6°-4° of valgus. The results of the articles evaluating the influence of potential risk factors were contradictory. Despite the low quality of the available evidence, the lateral closing and medial opening wedge high tibial osteotomy seem to remain valid long-term treatment options for patients with painful varus malalignment caused by isolated medial compartment osteoarthritis of the knee. The available results indicate that the need for arthroplasty could be delayed for more than 15 years in the majority of patients. However, higher-quality studies are needed to confirm these findings. As a systematic review is assigned a level of evidence equivalent to the lowest level of evidence used from the analyzed manuscripts, the level of evidence of this systematic review is IV.

Postoperative diagnostic revision for Crohn disease after subtotal colectomy for inflammatory bowel disease

PURPOSE

Subtotal colectomy (STC) is performed for severe acute and refractory colitis. The diagnosis can be difficult even after the surgery when colectomy specimen has overlapping features of ulcerative colitis (UC) and Crohn's disease (CD). The aim of this study was to evaluate the rate of postoperative diagnostic revision to CD after surgery and determine predictor factors.

METHODS

Retrospective study of 110 patients who underwent STC (2005-2018).

RESULTS

Preoperative diagnosis comprised UC = 80 (73%), CD = 11 (10%), and unclassified colitis (IBDU = 19, 17%). Initial diagnosis of IBDU and UC was modified to CD in 6 patients (6%) after STC. The final diagnosis after the follow-up of 10 ± 6 years switched from CD for 8 patients (9%). The multivariate analysis showed that patients with a colitis evolving for less than 10 years and initial diagnosis of IBDU were the two independent factors associated with an increased risk of diagnosis change to CD (p = 0.03; p = 0.016). At the end of the follow-up, 15 patients (14%) had a definitive stoma.

CONCLUSIONS

In patients with IBD, attention must be paid to determine the right restorative strategy to patients with an evolution of the disease less than 10 years or with IBDU who are more at risk to have a diagnosis change to CD after STC.

Surgical management of patients with ulcerative colitis during pregnancy: maternal and fetal outcomes

BACKGROUND AND AIMS

Ulcerative colitis can develop during the reproductive years, and there are limited data about perinatal care for patients with ulcerative colitis. In this study, we analyzed perinatal follow-up, complications, and maternal and fetal outcomes in pregnant patients undergoing surgery for ulcerative colitis.

METHODS

Between January 1998 and July 2013, female patients who underwent surgery during pregnancy for abdominal complications of ulcerative colitis and followed up during their pregnancy in our institution were included in our study. Patient characteristics, complications, operations performed, maternal and fetal morbidity and mortality during the perinatal period, and type of delivery were analyzed.

RESULTS

There were nine female patients with a median (range) age of 30 (21-33) years. Indications for surgery were fulminant/refractory colitis (n = 6) and bowel obstruction (n = 3). Operations performed were subtotal colectomy with an end ileostomy (n = 3), Turnbull blowhole procedure (n = 3), adhesiolysis with small bowel resection (n = 1), detorsion and decompression of bowel (n = 1) and adhesolysis (n = 1). Median (range) postoperative length of stay was 11 (5-28) days and median (range) duration of pregnancy was 36 (32-40) weeks. There were only two patients who had a transvaginal delivery, while a cesarean section was performed in seven patients. Indications for cesarean section were as follows: physician's preference (n = 4), planned small bowel surgery with cesarean section (n = 2), and metabolic disorders (n = 1). There were no perinatal maternal or fetal deaths.

CONCLUSIONS

Surgery for ulcerative colitis complications can be performed safely if indicated during pregnancy under the care of a multidisciplinary team that includes gastroenterologists, obstetricians, and colorectal surgeons.

Women's health issues after ileal pouch surgery

: Restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) is the surgical treatment of choice for patients with ulcerative colitis and familial polyposis who require colectomy. This surgical intervention allows for resection of colon, while offering intestinal continuity with fecal continence, discontinuation of most medications related to ulcerative colitis and reduction in the risk of colitis-associated neoplasia. As a proportion of these patients are women of childbearing age, it is important to understand the impact on reproductive health and function. Although limited data exist, restorative proctocolectomy/IPAA does not seem to adversely affect menstrual function. In general, sexual function is reported to improve postsurgery with the ability to achieve orgasm unaltered. However, dyspareunia is commonly reported post restoratively. Of concern, there are data to suggest that fertility is decreased post-IPAA. The reasons stated are pelvic adhesions and obstruction of fallopian tubes. Laparoscopic approach may improve fertility outcomes by reducing postoperative adhesions as compared with the open approach. Once achieved, pregnancy in patients with IPAA is characterized by a transient increase in stool frequency that resolves postdelivery. Whether vaginal delivery or cesarean section is preferred route of delivery in these patients is still controversial. But commonly cesarean section is advocated for patients' post-IPAA to prevent anal sphincter injury and long-term effects on pouch function. All of these issues should be included in the discussion with women who are contemplating IPAA, so they are well aware of them before deciding on the best management plan.

Primary ileo-anal pouch anastomosis in patients with acute ulcerative colitis

INTRODUCTION

Proctocolectomy with ileal pouch-anal anastomosis (IPAA) was performed in ulcerative colitis (UC) for emergent or urgent indications in three stages. Since the three-step procedure imposes enormous demands on a patient, there was an attempt to introduce primary IPAA for urgent indications. The aim of this study was to compare early complications after Hartmann's colectomy (HC) and IPAA in a selected group of patients.

MATERIAL AND METHODS

Medical records of 274 patients who underwent surgery for UC between 1996 and 2010 were retrospectively evaluated. Finally, a group of 77 patients with acute form of UC entered this study.

RESULTS

All patients were divided into two groups. Group 1 consisted of 32 (42%) patients who underwent HC, whereas group 2 comprised 45 (58%) patients after IPAA. There was no postoperative mortality. Respiratory failure occurred in 8 (24%) patients after HC and in 6 (14%) patients who underwent IPAA. Intra-abdominal sepsis developed in 4 (12%) patients after HC and in 8 (17%) undergoing IPAA. Fascia dehiscence was present in 3 (8%) patients after HC and in 4 (9%) with IPAA. Bowel obstruction occurred in 1 (4%) patient after the former operation and in 3 (6%) patients after the latter one. Wound infection was diagnosed in 6 (20%) patients after HC and in 9 (20%) after IPAA. The differences between the investigated groups of patients were not statistically significant.

CONCLUSIONS

The IPAA could be performed for urgent indications only in the patients with no critical dilatation of the colon or with active UC but without signs of severe malnutrition.

Surgical management of acute colitis and toxic megacolon

Toxic colitis, also known as fulminant colitis, or toxic megacolon when associated with bowel dilation, remains a significant emergent problem in patients with ulcerative colitis. The surgical options differ when compared with the patient undergoing elective resection for this disease and are influenced by the patients' overall medical status. Generally the options are total abdominal colectomy with ileostomy, and proctocolectomy with ileostomy or pouch reconstruction. In few circumstances, a decompressing colostomy and loop ileostomy may be performed. More recently, laparoscopy has been employed. The general surgical recommendations, indications, and techniques will be discussed.

Maternal and fetal outcome after colectomy for fulminant ulcerative colitis during pregnancy: case series and literature review

PURPOSE

Previous studies have reported high morbidity and mortality in mothers and their offspring after colectomy for ulcerative colitis during pregnancy. This study was designed to assess the maternal and fetal outcomes of pregnant females undergoing colectomy for ulcerative colitis in the current era.

METHODS

A retrospective analysis was performed at our institution of all pregnant females undergoing operation for ulcerative colitis between 1980 and 2004. To compare this data to that of past literature, a MEDLINE search from 1951 to 2004 reviewed all cases reported on this topic.

RESULTS

Between 1980 and 2004, five females underwent an operation at our institution for fulminant ulcerative colitis while pregnant. All five patients underwent subtotal colectomy with Brooke ileostomy. Postoperative maternal morbidity included a superficial wound infection and a small asymptomatic intra-abdominal abscess. All females had successful pregnancies, and no maternal or fetal deaths occurred. Two patients went on to have an ileal pouch-anal anastomosis, one had a completion proctectomy and end ileostomy, one is scheduled for an ileal pouch-anal anastomosis, and one patient is lost to follow-up. The literature review revealed 37 cases. The overall fetal and maternal mortality was 49 and 22 percent respectively. Postoperative maternal morbidity was reported in 24 percent.

CONCLUSIONS

In contrast to historic data, the maternal and fetal mortality from our series was zero and maternal morbidity was low. Subtotal colectomy and Brooke ileostomy for ulcerative colitis during pregnancy is safe. A multidisciplinary team that includes a gastroenterologist, high-risk obstetrician, and experienced surgeon is necessary for an optimal outcome.

Management of fulminant ulcerative colitis by primary restorative proctocolectomy

Severe acute ulcerative colitis unresponsive to medical management is characterized by multiple associated risk factors including anemia, hypoproteinemia, and high steroid requirements when urgent surgery is required. Current surgical options include use of primary ileal pouch-anal anastomosis (IPAA) vs. historic trends favoring colectomy with ileostomy.

PURPOSE

To evaluate the efficacy of primary IPAA in patients with severe colitis, we reviewed our own experience in 20 patients with this condition.

METHODS

Patients undergoing primary restorative proctocolectomy included 13 males and 7 females (mean age, 30.5 +/- 2.4 years). Exclusion criteria for primary reconstruction included septic patients and patients with associated medical conditions such as pulmonary or cardiovascular disease. History of ulcerative colitis averaged 3.1 +/- 1.1 years (range, 1 month to 19 years). Preoperative mean total serum protein concentration was 5.0 +/- 0.2 g/dl, and mean albumin concentration was 2.1 +/- 0.2 g/dl, reflecting disease severity. The average daily steroid requirement at the time of urgent colectomy was 58.0 +/- 4.4 mg of prednisone (or intravenous equivalent). Primary IPAA included 18 "W" reservoirs, 1 "S" reservoir, and 1 "J" reservoir.

RESULTS

Major surgical complications included mild pancreatitis (10 percent), anastomotic leak (5 percent), adrenal insufficiency (15 percent), an upper gastrointestinal bleed (5 percent), and small bowel obstruction (15 percent). There were no deaths, and no patients developed pelvic sepsis or required IPAA removal. At three and twelve months, 24-hr stool frequency averaged 7.3 +/- 0.4 and 4.9 +/- 0.3, respectively. Overall day and night continence was excellent and not different from patients who underwent elective IPAA procedures for ulcerative colitis.

CONCLUSIONS

Improved options such as primary IPAA may be safely used in selected patients requiring urgent surgery for severe or fulminant ulcerative colitis. Medical management should be abbreviated when disease control cannot be promptly achieved.

Topical anticolitic efficacy and selectivity of the glucocorticoid budesonide in a new model of acetic acid-induced acute colitis in the rat

AIMS

To study the effect of local or parenteral administration of the glucocorticoid budesonide in the acetic acid-induced colitis model in the rat.

METHODS

Colitis was induced in an exteriorized colonic segment by administration of 4% acetic acid for 15 s. Four days later, this colonic segment with colitis was examined using a morphological scoring system, and measurements of myeloperoxidase activity and of plasma exudation into the colonic segment. The experimental colitis showed morphological similarities to human ulcerative colitis, with 3-fold increase in myeloperoxidase activity and 6-fold increase in the plasma exudation. Budesonide in different doses administered for 3 days, starting one day after acetic acid instillation, prevented the development of colitis in a dose-dependent manner. The best effect of budesonide on the morphological score was achieved after local treatment at a dose of 10(-5) M twice daily (76% reduction compared with a control colitis group) and parenteral treatment with 0.75 mg/kg (80% reduction). These doses also normalized myeloperoxidase activity and significantly reduced the plasma exudation. The systemic effects of the drug were most pronounced in the group treated with parenteral budesonide. This group showed the greatest reduction in body weight and a significant reduction of the weight of adrenal glands and spleen (as compared to controls). Thymus weight in animals treated systemically was significantly lower than in locally treated animals. In the group treated with local budesonide the weight of adrenals was reduced. However, the weights of spleen and thymus were not reduced and the reduction of the body weight was even less than in the control group.

CONCLUSION

Local treatment with budesonide at a dose of 10(-5) M (0.17 mg/kg if completely absorbed, but only 0.03 mg/kg with 15% bioavailability on colonic application) was as effective as parenteral treatment at a dose of 0.75 mg/kg in the attenuation of acetic acid-induced colitis in the rat, but resulted in minor systemic side-effects.

Management of the rectum following colectomy for acute colitis

During a 6 year period, 31 consecutive patients under the care of one surgeon had emergency colectomies for complicated colitis. A selective policy of closing the rectum intraperitoneally to minimize the length of retained diseased bowel and to avoid a mucus fistula was used during the study period. One patient underwent proctocolectomy, 7 subtotal colectomy with mucus fistula and 23 total colectomies with intraperitoneal closure of the rectum. Two patients (8.9%) developed pelvic sepsis. Both had intraperitoneal closure of the rectal stump and were readily managed by drainage into the stump. Subsequent surgery in the 18 patients having rectal excision has been uncomplicated. Intraperitoneal closure of the rectal stump in emergency surgery for complicated colitis can be performed safely in most of these patients.

Restorative proctocolectomy: the Irish experience. Irish Association of Coloproctology

Between January 1982 and March 1990, 106 patients underwent restorative proctocolectomy in eight separate surgical departments. The indication for operation was ulcerative colitis in 86%, familial adenomatous polyposis in 12% and megacolon in 2%. The age at operation was 33 +/- 2 years (mean +/- sem) (range 15-55 years). There were no perioperative deaths. The principal causes of post-operative morbidity were intra-abdominal sepsis (15%), anastomotic stricture (10%) and intestinal obstruction (8%). Intestinal continuity has been restored in 99 patients. All were grossly continent, but 32% experienced occasional soiling. The mean stool frequency was 5/day and 1/night. The overall failure rate was 6%. Eighty-nine percent of patients were happy with the outcome. We conclude that restorative proctocolectomy is safe and provides acceptable functional results. It should be the operation of choice in most patients with ulcerative colitis or familial adenomatous polyposis.
