During development, there is physiologic herniation of the midgut into the umbilical cord, and it then slips back in with a counterclockwise rotation. Jejunum and ileum occupy the mid abdomen and pelvis. The jejunum is involved in calcium and magnesium absorption. The ileum contains lymphoid tissue at the antimesenteric border. Small bowel infections present with a range of symptoms from diarrhea to severe dehydration to sepsis. Suspected SBO can be evaluated with plain radiography, upper GI studies, or CT. The treatment of SBO is initially nonoperative. Paralytic ileus occurs in many patients after abdominal surgery and is treated with IV fluids, nothing by mouth, and electrolyte replacement.

Background:The small intestine is the longest and convoluted portion in the digestive tract. It starts from pylorus and ends at ileocaecal valve. The small bowel consists of three parts measuring about 5 to 6 meters. The rst 25cm is the duodenum. Out of the rest part of small gut, jejunum th th. constitute the proximal 2/5 and ileum distal 3/5 The jejunum and ileum extend from the peritoneal fold that supports the duodeno-jejunal junction (Ligament of Treitz) down to ileocaecal valve. Material and Methods:All the patients admitted to PMCH, Patna and KMC, Katihar as intestinal obstruction was included for the study. The time period of study was from October 2014 to November 2016 in PMCH and December 2016 to January 2019 in KMC, Katihar. Out of all Intestinal obstruction 59 cases only of adult small gut obstruction were recorded for comparison and conclusive study.Conclusion: Small bowel obstruction remains a frequently encountered problem in abdominal surgery. Although modern day surgical management continues to focus appropriately on avoiding delayed operation, whatever surgery is indicated, not every patient is always best served by immediate operation

Abstract BACKGROUND Small bowel obscured its lesions as secrets which were difficult to diagnose before video capsule endoscopy as a new modality for investigation. Aim of the study Evaluation of video capsule endoscopy in comparison to radiological examination in detection of small bowel lesions. Patients and methods Fifty patients were recruited from Kafrawy Video Capsule Endoscopy Unit of Internal Medicine Department and endoscopy unit of Ain Shams University Hospital. The study included patients with occult or overt GIT bleeding, patients with unexplained microcytic iron deficiency anemia, patients with chronic diarrhea and abdominal pain, with normal upper GI endoscopy and colonoscopy. Exclusion of any patient younger than 18 years old, has intestinal stricture, achalasia, or dysphagia. All patients were studied biochemically with CBC and radiological by CT pelvis and abdomen with IV and oral positive contrast some of them were radiologically examined with CTE or CT mesenteric angiography. All patients were endoscopically examined by OGD, colonoscopy, VCE, and some of them were examined also with enteroscope. Results The study revealed that the detection rate of SB lesions with VCE was 84%. In the current study, (44%) of cases had AVMs, (72.73) % of them were above the age of forty five, and (27.27) % were below the age of forty five. All patients who were investigated with CT mesenteric angiography revealed negative results. In this study (20) % of patients had SB masses and polyps, (70) % of them were at age of forty five or more and only (30) % of them were below the age of forty five. All patients underwent CT pelvis and abdomen with IV and oral positive contrast, and we found that all patients had a negative results regarding the SB lesions. In comparison between CTE and VCE in detection of SB vascular lesions CTE did not detect SB vacular lesions. On the other hand, VCE detected the AVMs in the cases with negative CTE results. In this study one patient (2)% was diagnosed with hookworm infection. All patient underwent for OGD. We found that (20)% of patients had a significant gastric or duodenal lesions (proximal to the papilla) by VCE but missed by upper GI endoscopy. In our study the concomitant of VCE and enteroscope increase the detection of SB vascular lesions than isolated use of VCE only. Conclusion VCE has a high detection rate of SB lesions (84)%. CTE has a low significance in detection of SB vascular lesions and CT mesenteric angiography sensitivity relatively low. AVMs more common with increasing the age. PHE and SB ectopic varicies, were found to be common causes of GIT bleeding in CLD patient. There is a significant rate of missed gastric and duodenal (proximal to the papilla) lesions that the cause of GIT bleeding and unexplained iron deficiency anemia in OGD examination that were detected by VCE.

Abstract Background Small-bowel capsule endoscopy is advocated and repeat upper gastrointestinal (GI) endoscopy should be considered for evaluation of recurrent or refractory iron deficiency anemia (IDA). A new device that allows magnetic steering of the capsule around the stomach (magnetically assisted capsule endoscopy [MACE]), followed by passive small-bowel examination might satisfy both requirements in a single procedure. Methods In this prospective cohort study, MACE and esophagogastroduodenoscopy (EGD) were performed in patients with recurrent or refractory IDA. Comparisons of total (upper GI and small bowel) and upper GI diagnostic yields, gastric mucosal visibility, and patient comfort scores were the primary end points. Results 49 patients were recruited (median age 64 years; 39 % male). Combined upper and small-bowel examination using the new capsule yielded more pathology than EGD alone (113 vs. 52; P < 0.001). In upper GI examination (proximal to the second part of the duodenum, D2), MACE identified more total lesions than EGD (88 vs. 52; P < 0.001). There was also a difference if only IDA-associated lesions (esophagitis, altered/fresh blood, angioectasia, ulcers, and villous atrophy) were included (20 vs. 10; P = 0.04). Pathology distal to D2 was identified in 17 patients (34.7 %). Median scores (0 – 10 for none – extreme) for pain (0 vs. 2), discomfort (0 vs. 3), and distress (0 vs. 4) were lower for MACE than for EGD (P < 0.001). Conclusion Combined examination of the upper GI tract and small bowel using the MACE capsule detected more pathology than EGD alone in patients with recurrent or refractory IDA. MACE also had a higher diagnostic yield than EGD in the upper GI tract and was better tolerated by patients.

Abdominal Symptoms

Mesenteric venous thrombosis is a rare cause of intestinal ischemia which is potentially life-threatening because it can lead to intestinal infarction. Mesenteric venous thrombosis rarely develops after abdominal surgery and is usually associated with coagulation disorders. Associated symptoms are generally subtle or nonspecific, often resulting in delayed diagnosis. A 68-year-old woman underwent laparoscopic exploration for small bowel obstruction, secondary to adhesions. During the procedure, an intestinal perforation was identified and repaired. Postoperatively, the abdominal pain persisted and repeat exploration was undertaken. At repeat exploration, a perforation was identified in the small bowel with a surrounding abscess. After the second operation, the abdominal pain improved but anorexia persisted. Contrast enhanced abdominal computed tomography was performed which revealed superior mesenteric venous thrombosis. Anticoagulation therapy with heparin was started immediately and the thrombus resolved over the next 6 days. Although rare, this complication must be considered in patients after abdominal surgery with unexplained abdominal symptoms.

Abstract Background and Aims Intestinal failure [IF] is a feared complication of Crohn’s disease [CD]. Although cumulative loss of small bowel due to bowel resections is thought to be the dominant cause, the causes and outcomes have not been reported. Methods Consecutive adult patients referred to a national intestinal failure unit over 2000–2018 with a diagnosis of CD, and subsequently treated with parenteral nutrition during at least 12 months, were included in this longitudinal cohort study. Data were extracted from a prospective institutional clinical database and patient records. Results A total of 121 patients were included. Of these, 62 [51%] of patients developed IF as a consequence of abdominal sepsis complicating abdominal surgery; small bowel resection, primary disease activity, and proximal stoma were less common causes [31%, 12%, and 6%, respectively]. Further, 32 had perianastomotic sepsis, and 15 of those had documented risk factors for anastomotic dehiscence. On Kaplan-Meier analysis, 40% of all patients regained nutritional autonomy within 10 years and none did subsequently; 14% of patients developed intestinal failure-associated liver disease. On Kaplan-Meier analysis, projected mean age of death was 74 years.2 Conclusions IF is a severe complication of CD, with 60% of patients permanently dependent on parenteral nutrition. The most frequent event leading directly to IF was a septic complication following abdominal surgery, in many cases following intestinal anastomosis in the presence of significant risk factors for anastomotic dehiscence. A reduced need for abdominal surgery, an increased awareness of perioperative risk factors, and structured pre-operative optimisation may reduce the incidence of IF in CD.

Meckel’s diverticulum is the most common congenital abnormality affecting the gastrointestinal tract, affecting 4% of the general population. It is classically located on the antimesenteric border of the ileum within 100 cm of the ileocaecal valve. Complications may include haemorrhage, bowel obstruction, diverticulitis, perforation and malignancy. This report explores the case of intussusception in an adult, in association with a mesenteric Meckel’s diverticulum and adjacent benign polyp. A 40-year-old man presented with acute abdominal pain, affecting the central abdomen and both flanks. CT imaging revealed small bowel intussusception, with either a Meckel’s diverticulum or polyp acting as a lead point. Intraoperatively, the intussusception had already resolved; however, an inflamed outpouching was identified on the mesenteric border of the ileum, with a firm mass palpable within the bowel lumen. A 70 mm small bowel resection and primary anastomosis were performed. Histopathological analysis confirmed an inflamed Meckel’s diverticulum as well as an adjacent diverticulum comprising a benign polyp.

A 30-year-old male presented to the emergency room with complaints of periumbilical abdominal pain and vomiting. A contrast-enhanced computed tomography scan of the abdomen revealed subacute intestinal obstruction with dilated small bowel loops and associated bowel wall thickening of mid and distal ileal bowel loops. There was a fairly large small bowel diverticulum arising from the antimesenteric border of distal ileum. Findings were suggestive of small bowel diverticulitis or possibly focal enteritis. The patient was then immediately taken to the operating room for emergency laparotomy and was intra-operatively found to have a thickened Meckel’s diverticulitis with adjacent small bowel obstruction. Meckel’s diverticulectomy was performed in continuity with the adjacent inflamed small bowel. The patient had a stable post-operative course without any complications and was discharged within a week.
