Introduction Idiopathic, chronic, inflammatory diseases of GIT It includes ulcerative colitis, Crohn’s disease , and indeterminate colitis(15%). Anti-TNF agents the most effective available therapy Abdominal TB usually involves intestines, peritoneum, and mesenteric lymph nodes, commonest site being ileocecal region Typhoid fever is a major health problem 5/28/2024 temesgen d 4
Epidemiology of IBD Epidemoilogy ; Ulcerative colitis occurs in 8 to 15 people per 100,000 and peak age 3 rd and 7 th decade of life, Crohn’s disease occurr in 1 to 5 people per 100,000 between ages 15 to 30 years and ages 60 to 70 years. In 15% of patients with IBD are classified as having indeterminate colitis 5/28/2024 temesgen d 5
Etiology Enviromental factor;diet,microorganism,alcohol,oral contraceptive,smoking,location Genetics;account about 10-30%, There is a stronger genetic influence in CD compared with UC Thus, non-genetic factors may have a more important role in UC than in CD Immunity Antibiotics;due to shift of bacterial community structure NSAIDS . Appendectomy 5/28/2024 temesgen d 6
Clinical Manifestation UC Diarrhoea Rectal bleeding Rectal urgency Nocturnal defecation Tenesmu s Passage of mucopurulent exudates Crampy abdominal pain Systemic symptoms CD Diarrhoea Abdominal pain Weight loss Systemic symptoms Blood and/or mucus in the stool Obstruction Perianal fistula/abscess malnutrition 5/28/2024 temesgen d 7

Imaging Barium enema-lead pipe colon Abdominal x ray-in acute severe colitis see toxic megacolon or perforation CT scan-to see moderate to severe small bowel or colonic inflammation,intraabdominal or perianal abscess,and bowel obstruction chxs by transitional point and evaluation of enteric fistula U/S-to see stricture and fibrosis MRI-for perianal crohns diseasea 5/28/2024 temesgen d 13
Endoscopy Colonoscopy with terminal ileal intubation Findings abnormal erythematous mucosa ulcerations The most commonly used criterion for an abnormal finding is the presence of three or more ulcers in the absence of NSAID 5/28/2024 temesgen d 14
5/28/2024 temesgen d 15
Classification and Grading of IBD The Montreal classification and the Paris classification (for pediatric patients) remain the most well-accepted classification. 5/28/2024 temesgen d 16
Treatment of IBD Objective of treatment Induce remission Prevent relapse Treat complication Can be Surgical or Medical : 5/28/2024 temesgen d 17
Medical treatment of CD Antibiotics - role in the treatment of infectious complications,associated with Crohn’s disease,they are also used to treat,patients with perianal disease, enterocutaneous fistulas, and active colonic disease Aminosalicylates Corticosteroids Immunomodulators B iologic therapies 5/28/2024 temesgen d 18
Indications for surgical intervention in Crohn’s disease 5/28/2024 temesgen d 19
Emergency surgery Uncontrolled Hemorrhage Perforation Toxic megacolon Abscesses 5/28/2024 temesgen d 20
Preoperative considerations Preoperative high-dose glucocorticoids increase the risk of postoperative infectious complications and attempts should typically be made to wean glucocorticoids before surgical intervention. Immunomodulators are not associated with increased risk of postoperative infectious complications and do not typically need to be held before surgery Preoperative nutritional support for patients with malnutrition may decrease postoperative morbidity Smoking cessation may reduce postoperative morbidity in patients with Crohn’s disease 5/28/2024 temesgen d 21
General principles … Extent of resection 2cm margin = is similar to 12cm margin resection Feel normal bowel from mesenteric border Internal bypass Not advisable-risk of malignancy in bypassed segment Gastro-duodenal stricture- bypass can be used Anastomosis-comparable outcome Stapled or Hand sewn Side to side or End to End anastomosis Approach to mesentery- standard-clamp-tie technique -Gently tissue handling-risk of hematoma 5/28/2024 temesgen d 22
Cont.. Segmental intestinal resection of grossly evident disease followed by primary anastomosis is the usual procedure of choice An alternative to segmental resection for obstructing lesions is stricturoplasty 5/28/2024 temesgen d 23

Methods A prospective descriptive study of patients who presented with abdominal tuberculosis was conducted at Bugando Medical Centre (BMC) in northwestern Tanzania from January 2006 to February 2012. Ethical approval to conduct the study was obtained from relevant authorities. Statistical data analysis was performed using SPSS version 17.0. Results Out of 256 patients enrolled in the study, males outnumbered females. The median age was 28 years (range = 16–68 years). The majority of patients (77.3%) had primary abdominal tuberculosis . A total of 127 (49.6%) patients presented with intestinal obstruction, 106 (41.4%) with peritonitis, 17 (6.6%) with abdominal masses and 6 (2.3%) patients with multiple fistulae in ano. Forty-eight (18.8%) patients were HIV positive. A total of 212 (82.8%) patients underwent surgical treatment for abdominal tuberculosis. Bands /adhesions (58.5%) were the most common operative findings. Ileo-caecal region was the most common bowel involved in 122 (57.5%) patients . Release of adhesions and bands was the most frequent surgical procedure performed in 58.5% of cases . Complication and mortality rates were 29.7% and 18.8 % respectively. The overall median length of hospital stay was 32 days and was significantly longer in patients with complications ( p < 0.001). Advanced age (age ≥ 65 years), co-morbid illness, late presentation, HIV positivity and CD4+ count < 200 cells/ μl were statistically significantly associated with mortality (p < 0.0001). The follow up of patients were generally poor as only 37.5% of patients were available for follow up at twelve months after discharge. 5/28/2024 temesgen d 52

5/28/2024 temesgen d 61 Patients and Methods: The study retrospectively reviewed all patients diagnosed with typhoid perforation and managed in Damaturu and Potiskum district Hospitals North-Eastern Nigeria between January 2012 and December 2016. Results: A total of 279 patients were seen, 268 analyzed and 11 were excluded due to incomplete records. Age ranged from 3 to 50 years with male to female ration of 1.1:1 and a mean of 14.75 years. The peak age group was 11-20 years accounting for 39.93%. The clinical features were abdominal pain in 99.25 % and abdominal tenderness Perforations were single in 183 (68.28%) while 85 (31.72%) were multiple with 13 perforations in an individual being the highest in all patients. Procedures done were simple closure of perforation in 87.31% patients, resection and anastomosis in 70.84%. Post-operative complications were surgical site infection in 21.64%, and renal failure in 1.12%. The mortality was 14.18%.
SUMMARY IBD is comprised of two major disorders: ulcerative colitis and Crohn's disease Ulcerative colitis - relapsing and remitting episodes of inflammation limited to the mucosal layer of the colon Crohn's disease - transmural inflammation and by skip lesions Tuberculous enteritis consists of relatively vague, nonspecific symptoms and signs Intestinal perforation and bleeding are surgical complication of typhoid fever 5/28/2024 temesgen d 62
