RESUMO
BACKGROUND: Ingestion of gastrointestinal foreign bodies (FB) is a common clinical problem worldwide. Approximately 10-20% of FBs require an endoscopic procedure for removal, and < 1% require surgery. CASE DESCRIPTION: An 89-year-old male with Alzheimer's disease was hospitalized because of abdominal pain, abdominal distention, vomiting for three days, and cessation of bowel movements for six days. Abdominal computed tomography (CT) scan showed a small intestinal obstruction and an atypical FB in the small intestine. A pill and remaining plastic casing were removed from the small intestine during surgery. FB is a square with four sharp acute angles at its edge. The patient was discharged after two weeks of treatment, and no recurrence or complications were observed during the 6- month follow-up. CONCLUSION: Atypical intestinal FBs may cause misdiagnosis and easily lead to serious complications. Therefore, an appropriate radiological examination, such as CT, is necessary for unexplained intestinal obstruction. Symptomatic intestinal FBs should be actively removed to avoid serious complications.
.RESUMO
Peutz-Jeghers syndrome (PJS) is an autosomal dominant disorder characterized by hamartomatous polyposis of the gastrointestinal tract, melanin pigmentation of the skin and mucous membranes, and an increased risk for cancer. Radiological imaging, contrast studies, and scopy-directed biopsies confirm the diagnosis and help in surveillance. Hamartomatous mucosal polyps, which are characterized by a central core of branching smooth muscle connected to a mucosa unique to the site of origin, are pathognomonic for PJS. We present the case of a young male with a history of pain in the abdomen and vomiting. The patient had mucocutaneous pigmentations on the buccal mucosa. CT scan revealed jejuno-jejunal intussusception with multiple small and large bowel polyps causing acute intestinal obstruction. Intraoperatively, jejunal polyps were found to be the cause of jejuno-jejunal intussusception. Histopathology revealed hamartomatous polyps of PJS. Our interest in this case is due to the uncommon case of intussusception in an adult where radiological imaging played an important role in diagnosis.
RESUMO
Background Acute intestinal obstruction is a commonly encountered surgical emergency that is prevalent worldwide and has substantial morbidity and fatality rates. Therefore, swift and precise diagnosis is essential. While mortality rates in urban areas have declined due to timely medical intervention following early detection, the situation contrasts starkly in rural areas. Delays in presentations often lead to complications because of hesitancy toward surgery, economic challenges, and limited access to healthcare information. Therefore, this study aimed to evaluate how well multidetector computed tomography (MDCT) can help determine the site, cause, and level of intestinal obstruction compared to what the surgeons confirmed intraoperatively. Methodology A prospective study involving 101 patients was conducted at a tertiary care center in western Maharashtra from July 2022 to July 2024. The emergency department referred patients with clinical symptoms such as nausea and vomiting, abdominal distension, abdominal pain, inability to pass flatus, constipation, or diarrhea, which are commonly seen with intestinal obstruction. The study involved all patients who underwent a contrast-enhanced MDCT scan using both intravenous and oral contrast agents. We selected patients from both genders, regardless of their age; however, considerations were taken to include characteristics convenient and relevant to the study. Patients with abnormal serum creatinine levels or allergies to contrast were excluded from the study. We conducted CT examinations, noting findings such as the transition point between the dilated and collapsed loops, mesenteric fat stranding, and intestinal dilatation. An experienced radiologist made the final report, and the operating surgeons' notes on laparoscopy or open surgery for the same patient were reviewed to understand the operative findings. Results MDCT scans had high diagnostic accuracy for small and large bowel obstruction. Of the 101 patients, the mean age was 43.7 years. There were 70 (69.30%) males and 31 (30.69%) females. Sensitivity was 100%, specificity was 98.1%, positive predictive value was 83.7%, and negative predictive value was 100%. Conclusions MDCT demonstrated high sensitivity and specificity for diagnosing and determining the underlying cause of intestinal obstruction. It identified the location of the obstruction and discerned whether it originated from intrinsic, extrinsic, or intraluminal factors.
RESUMO
This case report describes a patient who presented with concern for a closed-loop small bowel obstruction (SBO). During exploratory laparotomy, an area of ischemic bowel due to closed loop obstruction was resected, along with an incidentally discovered inflamed-appearing Meckel's diverticulum (MD). The resected specimen contained a well-differentiated carcinoid tumor of benign behavior with a maximum diameter of 0.6 cm, which invaded the submucosal layer (pT1b and pN0). Over the last several years, there has been a debate with little consensus regarding the proper surgical management in the case of an asymptomatic MD that is discovered incidentally during abdominal exploration. The intention of sharing this case is to underline the importance of the decision-making process in treating patients with this intraabdominal pathologic condition found incidentally at the time of surgery.
RESUMO
Urgent investigation is crucial for infants with bilious vomiting, potentially indicating bowel obstruction. Upper gastrointestinal fluoroscopy aids diagnosis, but is not without its challenges. This case report describes a rare case of neonatal intestinal malrotation and mid-gut volvulus with an additional complication of congenital peritoneal encapsulation. Contribution: This case study offers insights into associated diagnostic challenges and underscores the value of utilising fluoroscopy in diagnosing complex gastrointestinal conditions.
RESUMO
OBJECTIVES: In gastroschisis, the intestines are exposed to amniotic fluid during pregnancy. The defect in the abdominal wall may also compress the mesentery and impair the intestinal blood supply. There is a varying degree of intestinal damage at birth. Complex gastroschisis is defined as gastroschisis with severe complications such as intestinal atresia, volvulus, necrosis and perforation. The aim of this study was to investigate long-term gastrointestinal morbidity and compare simple and complex cases. METHODS: A nation-wide retrospective cohort study with data from national registers was conducted. All children born with gastroschisis in Sweden from 1 January 1997 to 31 December 2016 were included in the study. Exposure was complex gastroschisis and the primary outcomes were intestinal failure and bowel obstruction. RESULTS: The study included 315 cases with gastroschisis, 260 classifieds as simple gastroschisis and 55 as complex. The median time to follow was 8 years. A significantly higher risk of developing intestinal failure (hazard ratio: 11.7) was found in complex cases. Nine percent of the complex cases underwent autologous gastrointestinal reconstructive surgery for intestinal failure, none of the simple cases did. The complex cases had a higher risk for bowel obstruction (hazard ratio: 4.3) with a higher proportion requiring surgery (18.2% vs. 6.9%) compared to simple cases. CONCLUSIONS: This nationwide study showed that the risk for intestinal failure and bowel obstruction is significantly higher for children with complex gastroschisis compared to simple gastroschisis. Most of the events occurred during the first 2 years of life.
RESUMO
BACKGROUND: Immunotherapy is used routinely for treating deficient mismatch repair (dMMR) colon cancer (CC). This case series highlights an emerging safety issue, where patients develop bowel obstruction associated with immunotherapy response. PATIENTS AND METHODS: Patients with dMMR CC who developed bowel obstruction while responding to immunotherapy were retrospectively identified. Data on patient, disease, treatment, and response-specific factors were explored for potential risk factors. Overall treatment numbers were used to estimate incidence. RESULTS: Nine patients from eight European centres were included. Common features were hepatic flexure location (5/9), T4 radiological staging (6/9), annular shape (8/9), radiological stricturing (5/9), and endoscopic obstruction (6/9). All received pembrolizumab and obstructed between 45 and 652 days after starting treatment. Seven patients underwent surgical resection; one was managed with a defunctioning stoma; and one was managed conservatively. One patient died from obstruction. Radiological response was seen in eight patients, including two complete responses. Pathological response was seen in all seven who underwent resection, including four complete responses. The overall incidence of immunotherapy response-related obstruction in these centres was 1.51%. CONCLUSIONS: Bowel obstruction associated with immunotherapy response may represent a rare treatment-related complication in dMMR CC. Clinicians must recognise this safety signal and share experience to maintain patient safety.
RESUMO
Gallstone ileus is a rare yet significant cause of mechanical bowel obstruction, particularly in elderly patients. This condition arises when gallstones migrate into the gastrointestinal tract through a cholecystoenteric fistula, often due to chronic inflammation. Despite medical advancements, gallstone ileus remains associated with high morbidity and mortality rates due to delayed diagnosis and nonspecific symptoms. The clinical presentation typically includes intermittent nausea, vomiting, abdominal pain, and constipation, which can obscure the diagnosis. Advanced imaging techniques, especially computed tomography (CT), are crucial for identifying key diagnostic features such as pneumobilia, ectopic gallstones, and signs of bowel obstruction. Gallstone ileus should be considered in any case of small bowel obstruction, even if CT imaging is inconclusive, as gallstones can be radiolucent. Indirect clues like pneumobilia and dilated small bowel loops can lead to the diagnosis. Effective management of gallstone ileus requires prompt surgical intervention to remove the obstructing gallstone and restore bowel patency. The primary surgical procedure is enterolithotomy, although additional procedures such as cholecystectomy and fistula repair may be necessary depending on the patient's condition and intraoperative findings. The choice of surgical approach should be individualized, considering the patient's overall health and the specific characteristics of the obstruction. Early recognition and timely surgical management are essential to prevent complications and improve patient outcomes.
RESUMO
Intussusception is the invagination of one segment of the bowel into the adjacent bowel segment leading to obstruction, intestinal ischemia and, in severe cases, peritonitis and perforation. While the condition is more common in children, adult intussusception does occur and is often attributed to malignancy. In this case report, we discuss an adult man who presented for weight loss and intermittent abdominal pain and was ultimately found to have ileocecal intussusception on CT imaging. A colonoscopy with cold biopsy was performed and pathology reports displayed a well-differentiated neuroendocrine tumor lead point; a rare event with only a few cases reported. Ultimately, the patient was taken to the operating room, and an ileocecectomy was performed with primary anastomosis. Prompt diagnosis and management are crucial in adult intussusception as a missed event can lead to tumor progression, bowel ischemia, bleeding and necrosis.
RESUMO
Ileo-ileal intussusception, an infrequent cause of small bowel obstruction in adults, can be initiated by inflammatory fibroid polyps. These are uncommon, benign submucosal lesions of the gastrointestinal tract. This case report explores an adult patient with inflammatory fibroid polyps-induced ileo-ileal intussusception.
RESUMO
BACKGROUND: Superior mesenteric artery syndrome is a rare condition that has only around 400 reported cases so far. Typically, the superior mesenteric artery branches off the abdominal aorta at 45° to create an aortomesenteric distance of 10-28 mm, with the duodenum passing through. However, if this aortomesenteric angle reduces to less than 25°, the third portion of the duodenum becomes compressed between the SMA and aorta, causing mechanical obstruction. CASE PRESENTATION: This case report aims to demonstrate the diagnostic difficulties and the laparoscopic management of a 52-year-old Indian male presenting with abdominal pain and vomiting, with associated weight loss. Imaging was further suggestive of high intestinal obstruction, and he was later found to have superior mesenteric artery syndrome. CONCLUSION: Taking into account a significant reduction in morbidity, we propose laparoscopic duodenojejunostomy to be the new procedure of choice for superior mesenteric artery syndrome.

INTRODUCTION AND IMPORTANCE: Intussusception in adults is rare, constituting a miniscule number of bowel obstruction pathologies. Clinical practice often considers it a last-resort diagnosis, as other causes of mechanical small bowel obstruction are more common. The diagnosis is a challenging one to make, as the "telescoping" motion of the intestines fluctuates in a waxing-and-waning nature. In adults, the etiology is predominantly a pathological lead point being either benign or malignant. When encountering an obscure cause of abdominal pain, intussusception caused by a small bowel lipoma may be the culprit. CASE PRESENTATION: In this unique case, we present the journey of a 55-year-old Emirati male who presented with severe abdominal pain, nausea and vomiting. The patient underwent various imaging modalities, initially an "incidental" lipoma finding in the terminal ileum until a diagnosis of ileo-ileal intussusception emerged in later imaging, given its unusual and fluctuating nature. Ultimately, a resection of the bowel segment with side-to-side anastomosis was done. CLINICAL DISCUSSION: This case report aims to illuminate the diverse clues and incidental findings encountered during our patient's path to a diagnosis. By exploring the elements of this patient's journey to a diagnosis, we aspire to aid future clinicians in navigating the challenges of identifying obstructive pathologies and considering intussusception as a rare yet crucial differential diagnosis. CONCLUSION: This case highlights the importance of a comprehensive approach to diagnosis and management of patients presenting with obstructive symptoms, incorporating both clinical insight and imaging modalities such as CT to ensure optimal patient outcomes. When confronting such an obscure cause of abdominal pain, intussusception caused by a small bowel lipoma may be the culprit.
RESUMO
Meckel's diverticulum (MD), a rare congenital abnormality, can lead to issues like diverticulitis and bleeding. Foreign bodies in MD are even rarer, causing vague symptoms and perforation, requiring urgent surgery. This case report highlights a patient with a foreign body in MD, focusing on clinical presentation and management. A 55-year-old male presented with abdominal pain, nausea, and vomiting. Computed tomography scan revealed a foreign body perforating the small bowel. Exploratory laparotomy found a partially perforated MD with a foreign body. Diverticulectomy was performed, and the patient recovered, discharged the next day. Foreign bodies in MD are exceedingly rare and can cause inflammation, infection, and perforation, mimicking appendicitis. Diagnosis is challenging due to nonspecific symptoms, with imaging and clinical evaluation crucial. Surgical intervention, like diverticulectomy, is primary. Early diagnosis and prompt surgery are critical in managing MD complicated by foreign bodies, ensuring favorable outcomes. This report underscores symptom recognition and effective management strategies.
RESUMO
INTRODUCTION AND IMPORTANCE: Small bowel obstruction (SBO) is a common surgical emergency with various causes. However, SBO resulting from appendicitis is uncommon and often overlooked. Appendico-ileal knotting, a rare and dangerous form of SBO, occurs when the appendix becomes twisted around the small intestine, leading to strangulation. Despite being reported since 1901, there have been very few documented cases of this condition. Diagnosing appendico-ileal knotting preoperatively is challenging, and even imaging techniques like computed tomography scans may not provide definitive diagnostic findings. Our current case report is a valuable addition to the limited literature and enhances understanding of this infrequent cause of SBO from a resource limited setting. CASE PRESENTATION: We present the case of a 28-year-old female who presented with symptoms of dynamic SBO, including abdominal pain, vomiting, and constipation. Preoperative evaluation couldn't determine the exact cause. CLINICAL DISCUSSION: Diagnosis of a strangulated ileum was discovered, with the appendix identified as the source intraoperatively, leading to an open retrograde appendectomy. Postoperatively, the patient received IV ceftriaxone (1 g daily), metronidazole (500 mg tds), paracetamol (1 g tds), and IV crystalloids. Oral intake resumed gradually, and discharge occurred on day 4. Follow-up on 10th day was uneventful. CONCLUSION: Appendico ileal knotting is a rare cause of mechanical SBO. Knowledge of its pathophysiology, diagnosis, and management is very crucial to reduce its associated morbidity and mortality.
RESUMO
While bowel obstruction is the most common surgical disorder of the small intestine, small bowel obstruction due to Meckel's diverticulum is a relatively rare occurrence. We encountered a compelling case of small bowel obstruction that turned out to be more complex than anticipated, involving a Meckel's diverticulum with some unforeseen findings. We followed standard guidelines for history-taking, examination, investigations, and management of the intestinal obstruction. After exhausting conservative treatment options, we opted for surgical intervention, and the unexpected cause of the obstruction took us by surprise. This case report highlights an exceedingly rare entity: Meckel's diverticulum precipitating uncommon complications.
RESUMO
Video capsule endoscopy (VCE) is used to evaluate the gastrointestinal tract, particularly the small bowel for obscure bleeding, Crohn's disease, and tumors. A rare complication of VCE is the retention of the pill camera. With the expanding use of VCE, it's important to consider the pathology that may lead to retention and approach to treatment. VCE for subacute or intermittent bowel obstruction is considered a contraindication due to the increased risk of retention, however, it may also identify significant pathology. Capsule retention should be treated promptly to prevent complications such as acute small bowel obstruction (SBO) and perforation. This case describes a 51-year-old female who presented with retention of two VCE cameras in the bowel for multiple years. She had intermittent abdominal pain and partial SBOs before the retention. She underwent a successful laparoscopic-assisted surgery removing the two endoscopy cameras and resection of the stenosed small bowel. This case sheds light on the challenges and opportunities in the management of VCE and capsule retention.
RESUMO
INTRODUCTION: Abdominal adhesions represent a chronic postsurgical disease without reliable prophylaxis. Animal modeling has been a cornerstone of novel therapeutic development but has not produced reliable clinical therapies for prevention of adhesive small bowel obstruction. The purpose of this scoping review is to analyze animal models for abdominal adhesion generation by key considerations of external validity (i.e., fidelity, homology, and discrimination). METHODS: A literature review was performed in accordance with the Preferred Reporting Items for Systematic Reviews Extension for Scoping Reviews guidelines. Peer-reviewed publications were included that described the development or quality assessment of experimental animal models for abdominal adhesions with inclusion of a scoring system. Studies that focused on treatment evaluation, implantation of surgical devices, models of nonsurgical etiologies for abdominal adhesions, non-in vivo modeling, and investigations involving human subjects were excluded. RESULTS: Four hundred and fifteen (n = 415) articles were identified by prespecified search criteria. Of these, 13 studies were included for review. CONCLUSIONS: Translation of investigational therapeutics for abdominal adhesion prevention is dependent upon high-quality experimental animal models that reproduce the clinical adhesions seen in the operating room as a disease of the entire abdomen.
RESUMO
BACKGROUND: Early small bowel obstruction (eSBO) (within 30-days) is a rare but important complication that is associated with high rates of morbidity, including readmission, reintervention, and reoperation. OBJECTIVES: To identify patient-specific and operation-specific characteristics that predispose patients to eSBO and to identify at-risk individuals preoperatively. SETTING: 2015-2021 Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP). METHODS: Utilizing the 2015-2021 MBSAQIP PUF, 1,016,484 records were analyzed. Pediatric, revisional, open-conversion, and cases with incomplete data in sex, body mass index, operative-time, 30-day-follow-up variables were excluded. Case details were compared using Fisher's exact & Wilcoxon -Mann -Whitney tests to identify at-risk patients. The likelihood of eSBO was modeled with rare event logistic regression. RESULTS: Incidence of eSBO was .40%. Of the 4103 occurrences of eSBO, RYGB (Roux-en-Y gastric bypass), SG (sleeve gastrectomy), and DS (duodenal switch) accounted for 79.4%, 19.3%, and 1.3%, respectively. Many patient-specific characteristics were significantly associated with eSBO. History of prior foregut surgery, a non-metabolic surgery trained operator, and longer operative times were all associated with increased eSBO (P < .0001). While simultaneously controlling for these factors, eSBO remained higher in DS (OR 9.55, P < .0001) and RYGB (OR 5.18, P < .0001) compared to SG. Increased length of operation (OR 1.03, P < .0001) and non -MS-trained operators (OR 1.33, P < .0001) remained highly significant. Male-sex (OR .70, P < .0001) and diabetes (OR .78, P < .0001) were both protective. CONCLUSIONS: In the largest analysis to date, eSBO remains a rare event. RYGB accounts for the largest proportion of eSBO, however, DS has a higher risk adjusted rate of eSBO.
RESUMO
INTRODUCTION AND PURPOSE OF THE STUDY: Small bowel obstruction (SBO) accounts for a substantial proportion of emergency surgical admissions. Malignancy is a common cause of obstruction, either due to a primary tumour or intra-abdominal metastases. However, little is known regarding the current treatment or outcomes of patients with malignant SBO. This study aimed to characterise the treatment of malignant SBO and identify areas for potential improvement and compare overall survival of patients with malignant SBO to patients with non-malignant SBO. MATERIALS AND METHODS: This was a subgroup analysis of a multicentre observational study of patients admitted with SBO. Details regarding these patients' diagnoses, treatments, and outcomes up to 1-year after admission were recorded. The primary outcome was overall survival in patients with malignant SBO. RESULTS: A total of 316 patients with small bowel obstruction were included, of whom 33 (10.4%) had malignant SBO. Out of the 33 patients with malignant SBO, 20 patients (60.6%) were treated with palliative intent although only 7 patients were seen by a palliative team during admission. Nutritional assessments were performed on 12 patients, and 11 of these patients received parenteral nutrition. 23 patients underwent surgery, with the most common surgical interventions being loop ileostomies (9 patients) and gastrointestinal bypasses (9 patients). 4 patients underwent right hemicolectomies, with a primary anastomosis formed and 1 patient had a right hemicolectomy with a terminal ileostomy. Median survival was 114 days, and no difference was seen in survival between patients treated with or without palliative intent. CONCLUSION: Malignant SBO is associated with significant risks of short-term complications and a poor prognosis. Consideration should be given to the early involvement of senior decision-makers upon patient admission is essential for optimal management and setting expectation for a realistic outcome.
