RESUMEN
Objectives: We aimed to evaluate the usefulness and acceptability of CapsoCam Plus (CapsoCam) in Japanese patients. Methods: This retrospective single-center study enrolled 930 patients with suspected small-bowel bleeding (SSBB) who underwent capsule endoscopy. Thirty-three patients using CapsoCam and PillCam SB3 (SB3) were matched using propensity score matching. The diagnostic yield and the acceptability of CapsoCam were evaluated. Results: There was no SSBB case where capsule endoscopy was performed within 48 h of bleeding. CapsoCam had a significantly higher observation rate of the entire small bowel (97% vs. 73%, p = 0.006) and Vater's papilla (82% vs. 15%, p < 0.001) than SB3. The reading time of CapsoCam was significantly longer than that of SB3 (30 vs. 25 min, p < 0.001), and CapsoCam's time from the capsule endoscopy swallowing to read completion was longer than that of SB3 (37 vs. 12 h, p < 0.001). The two groups showed no difference in the capsule endoscopy findings according to the P classification. Notably, 85% of the patients using CapsoCam reported examination distress as "not at all" or "almost not," and 94% reported swallowing difficulty as "very easy" or "easy." Conclusions: CapsoCam took time to read; however, it is a well-tolerated examination with a high observation rate of Vater's papilla and entire small-bowel mucosa. Detectability of bleeding sources was comparable in both modalities for cases of occult SSBB and overt SSBB more than 48 h after bleeding. CapsoCam is a useful modality for patients with SSBB.
RESUMEN
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.
.RESUMEN
Introduction: The one-anastomosis gastric bypass (OAGB), first published by Dr Rutledge in 1997 is now a well-established procedure in the bariatric-metabolic armamentarium. This procedure based on a (single) loop gastro-jejunal anastomosis (the biliopancreatic limb or BPL) with a long narrow gastric pouch combines restriction with hypo-absorption. The biliopancreatic limb and in particular its length is held responsible for the degree of the hypo-absorptive effect but the most appropriate or "optimal" length of the BPL remains debatable. Methods: The following text is based on a comprehensive and meticulous selection of the most recent literature in Cochrane, Pubmed and Google Scholar using the search terms "biliopancreatic limb", "biliopancreatic limb in one anastomosis gastric bypass" in an attempt to define not only the most common used biliopancreatic limb length but also to find out If there is an "ideal" limb length not only to optimize the outcomes of the OAGB in terms of weight loss and resolution of obesity-related diseases but also to reduce the potential side-effects in particular nutritional deficiencies. Results: Until today there is no consensus about the "standard" or "ideal" length of the biliopancreatic limb in OAGB, a fixed length of 200 cm is still the most common used procedure although many reports and studies are in favour of shorter limb lengths adjusted to the BMI or the total small bowel length. Conclusion: The "ideal" or "optimal" biliopancreatic limb length in OAGB still needs to be defined. There are different options and all of them have their credits, the question remains if a consensus can be reached regarding the best strategy to obtain the best outcome.
RESUMEN
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.
RESUMEN
BACKGROUND: The diagnosis of small bowel motility disorders is performed by manometric evaluation of the contractile patterns of the small intestine. Conventional intestinal manometry systems include few pressure sensors at relatively long intervals. We have recently shown that high-resolution jejunal manometry, with multiple closely spaced recording sites, allows the analysis of propagation patterns of intestinal motility in healthy subjects that cannot be detected with conventional manometry. The objective of this pilot study was to explore the feasibility and diagnostic value of high-resolution intestinal manometry in patients with suspected small bowel dysmotility. METHODS: Prospective pilot study evaluating intestinal motility patterns in 16 consecutive patients (16-61 years; 11 women) with severe, chronic digestive symptoms referred for the evaluation of intestinal motility and in 18 healthy controls (21-38 years; 8 women). A 36-channel high-resolution manometry catheter was orally placed under radiological guidance in the jejunum. Intestinal motility was continuously recorded for 3 h fasting and 2 h after a 450 kcal meal. The manometric recordings were analyzed in two formats: (a) with the high-resolution data from 34 channels and (b) showing only the recordings from 5 channels separated by 7 cm intervals, mimicking a conventional manometry recording. KEY RESULTS: In the analysis mimicking conventional manometry, abnormal motility criteria were detected in six patients and in no healthy subject [bursts (n = 3), postprandial minute rhythm (n = 1) and myopathic pattern (n = 2)]. These classical dysmotility criteria were also detected by high-resolution manometry. High-resolution analysis detected one or more abnormal findings in seven additional patients that were not observed in any healthy subject, specifically: (a) abnormal propagation of Phase III (n = 3); (b) reduced propagated activity during Fasting Phase II (n = 4); (c) increased propagated activity during Fasting Phase II and postprandial phase (n = 1). CONCLUSIONS AND INFERENCES: This pilot study suggests that high-resolution intestinal manometry may improve the sensitivity of conventional manometry in the detection of intestinal motor dysfunction.
RESUMEN
Bezoars are indigestible masses of material forming within the gastrointestinal system. Phytobezoars are the most common subtype consisting of plant matter such as fibre, skins, and seeds. Rarely they present causing small bowel obstruction (SBO) and may be difficult to distinguish from faecalization on imaging. Here we present the case of a man in his 70s who rapidly consumed an expiring bag of peanuts and subsequently developed a SBO due to formation of a peanut phytobezoar. After failing conservative management, he required emergency surgery with intentional enterotomy to milk out the bezoar. This case highlights the importance of maintaining a broad differential and thorough history taking in patients presenting with SBO.
RESUMEN
Adhesive small bowel obstruction is thought to be a disorder limited to the jejunum and ileum. As a result, the list of aetiologies for duodenal obstruction does not include adhesions. We report the case of a patient who presented with gastric outlet obstruction (GOO), but with no lesions identified on cross-sectional imaging or endoscopy. Laparoscopy revealed duodenal adhesions as the cause of her GOO. Kockerization of the duodenum led to resolution of her symptoms. This previously undocumented finding leads us to suggest that laparoscopy should be considered in patients who have features highly suspicious for GOO, but have no cause identified on investigation.
RESUMEN
Paraduodenal hernias are a rare but important clinical entity, as their presentation can be life-threatening if not properly diagnosed and managed appropriately. Additionally, this entity is defined by a unique and complex congenital anatomical abnormality which dictates a specific treatment algorithm. Here we present the cases of three patients from our clinical experience who all presented with either acute or chronic small bowel obstructions secondary to paraduodenal hernias. Two were left-sided paraduoenal hernias and one was right-sided. All three patients were successfully managed with surgical intervention. An appreciation of paraduodenal hernias, including the defining anatomy and methods of surgical management, is important for the general surgeon.
RESUMEN
We present a case of a 60-year-old male with known seropositive rheumatoid arthritis and cerebral vasculitis who presented to the emergency room with abrupt onset lower back and abdominal pain. The patient developed peritonitis which led to an abdominal laparotomy where jejunal ischemia, necrosis, and perforation were found, requiring bowel resection. On pathology examination, the patient had mesenteric vessel intramural inflammation indicative of vasculitis. He developed an anastomotic leak on postoperative Day 4 and elected hospice care. A high index of suspicion for mesenteric vasculitis should be considered in patients presenting with abdominal pain in the setting of known rheumatoid arthritis associated vasculitis, especially patients with long-standing rheumatoid arthritis. The high mortality represented by gastrointestinal involvement in rheumatoid arthritis associated vasculitis warrants investigation in high-risk patients, despite its low prevalence. Treatment may consist of high-dose corticosteroids, immunosuppressive agents, biologic therapies that target the underlying autoimmune process, and in severe cases, bowel resection.
RESUMEN
Crohn's disease (CD) is a chronic inflammatory bowel disease (IBD) that frequently affects the small bowel. Individuals diagnosed with CD are at increased risk of developing bowel cancer compared to the general population. Small bowel cancer is a rare but significant CD complication. Adenocarcinoma represents the most prevalent of these neoplasms, followed by neuroendocrine tumors and sarcomas. The primary risk factors identified are being of the male sex, disease duration, previous surgical intervention, perianal disease, and chronic inflammation. The precise etiology remains unclear. Another crucial issue concerns the role of immunomodulators and advanced therapies. By inhibiting inflammation, these therapies can reduce the risk of cancer, which is often initiated by the inflammation-dysplasia-adenocarcinoma sequence. In accordance with the most recent guidelines, it is not necessary to conduct surveillance in patients with small bowel cancer among CD patients, as it is considered a rare disease. Nevertheless, it is of significant importance for gastroenterologists to be aware of this potential CD complication, as well as the patients who are most at risk of developing it. The purpose of this review is to provide a comprehensive overview of CD-SBC, focusing on epidemiology, etiopathogenesis, risk factors, diagnosis, and the role of advanced therapies in CD-SBC.
RESUMEN
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.
RESUMEN
Background: Small bowel adenocarcinoma (SBA) is a rare gastrointestinal malignancy with an increasing incidence and a high propensity for liver metastasis (LM). This study aimed to investigate the risk factors for synchronous LM and prognostic factors in patients with LM. Methods: Utilizing the Surveillance, Epidemiology, and End Results (SEER) database, this study analyzed data from 2,064 patients diagnosed with SBA between 2010 and 2020. Logistic regression was used to determine risk factors for synchronous LM. A nomogram was developed to predict the risk of LM in SBA patients, and its predictive performance was assessed through receiver operating characteristic (ROC) curves and calibration curves. Kaplan-Meier and Cox regression analyses were conducted to evaluate survival outcomes for SBA patients with LM. Results: Synchronous LM was present in 13.4% of SBA patients (n = 276). Six independent predictive factors for LM were identified, including tumor location, T stage, N stage, surgical intervention, retrieval of regional lymph nodes (RORLN), and chemotherapy. The nomogram demonstrated good discriminative ability, with an area under the curve (AUC) of 83.8%. Patients with LM had significantly lower survival rates than those without LM (P < 0.001). Survival analysis revealed that advanced age, tumor location in the duodenum, surgery, RORLN and chemotherapy were associated with cancer-specific survival (CSS) in patients with LM originating from SBA. Conclusions: This study highlights the significant impact of LM on the survival of SBA patients and identifies key risk factors for its occurrence. The developed nomogram aids in targeted screening and personalized treatment planning.
RESUMEN
Encapsulating peritoneal sclerosis (EPS) is a serious complication of chronic peritoneal dialysis (PD) that results in encapsulation of the bowel in a thick, fibrocollagenous membrane. Given its rare and complex nature, diagnosis of EPS often arises late in the disease process or intraoperatively. We report the case of an 86-year-old male with a history of renal failure managed with PD who presented with multiple hospital admissions for recurrent abdominal pain and symptoms of small bowel obstruction. Open laparotomy revealed encasement of the entire abdominal cavity in a cocoon-like membrane, consistent with EPS, which was successfully managed with extensive excision and adhesiolysis. This discussion, enriched by unique radiographic insights and delineation of a surgical strategy, seeks to enhance the understanding of this underreported disease characterized by a lack of definitive treatment and an enigmatic pathophysiology.
RESUMEN
Background: Small bowel capsule endoscopy (SBCE) is an essential tool for evaluation of small bowel (SB) Crohn disease (CD). Fecal calprotectin (FC) represents an important biomarker of intestinal inflammation, widely used in ulcerative colitis and CD. Our aim was to evaluate the role of FC for diagnosing inflammatory activity in patients with isolated SB CD and how it correlates with SBCE findings. Methods: This is a retrospective study conducted in a tertiary inflammatory bowel disease referral center that included patients with SB CD who underwent SBCE between January 2017 and February 2023. FC value was obtained from the closest stool examination to SBCE. Results: One hundred ninety-six patients were included: 123 were women (63%) with a mean age of 44.2 years. In the SBCE, 127 (65%) patients had a Lewis Score ≥135 and, among the 94 patients with FC >200 µg/g, 23 had LS <135, 36 had LS between 135 and 790, and 35 had LS ≥790. FC levels were predictive of endoscopic lesions in SBCE, with significant correlation between FC level and total LS (Pearson correlation coefficient 0.43, P<.001). The sensitivity and specificity were calculated for each cut-off value being respectively 78% and 45% for FC = 100 µg/g, 69% and 59% for FC = 150 µg/g and 67% and 67% for FC = 200 µg/g. Conclusion: FC showed moderate correlation with endoscopic findings in SBCE in SB CD. It is, therefore, a reasonable marker for predicting significant inflammatory lesions in SBCE; however, none of the cut-off had a high sensitivity or specificity.
RESUMEN
Background: Adhesive small bowel obstruction (ASBO) is a common acute abdominal complication. Although non-surgical treatment is the primary treatment approach, more and more studies show that surgical treatment can reduce the incidence rate. Laparoscopic adhesiolysis (LA) has many advantages of minimally invasive surgery.But not all patients with ASBO are suitable for LA. Objective: The aim of this scoping review was to summarize the keys to successful LA by analyzing the extensive literature. Methods: A literature search was conducted in PubMed for articles on laparoscopic treatment of ASBO published between January 2000 and February 2024. This scoping review followed the framework suggested by Arksey and O'Malley for a scoping review. Results: By analyzing the included studies we found that LA does have many advantages and can be performed safely. However, the prerequisite is to select patients with simple adhesions whenever possible and to focus on reasonable intraoperative measures. To improve the success rate of LA, we summarized the following characteristics of patients: no contraindications related to pneumoperitoneum, few previous abdominal operations (≤2), no pregnancy, bowel dilatation < 4 cm in diameter, simple adhesions, no diffuse peritonitis, no history of abdominal radiotherapy, <24 h of ASBO, limited previous abdominal surgery (appendix, cholecystectomy), no bowel strangulation ischemia, and bowel necrosis or bowel resection required for other reasons. In addition, we also summarized reasonable intraoperative measures. Conclusions: Laparoscopic adhesiolysis has many advantages.Specific patients can benefit from LA. This scoping review Summarized the conditions for patient screening and reasonable intraoperative measures with the aim of providing a reference for surgeons, thereby ensuring that more patients benefit from LA.
RESUMEN
Small bowel into small bowel intussusception can present with symptoms similar to those observed in patients with more common small bowel into large bowel intussusception. In most cases, intussusceptions isolated to the small bowel are self-limited and less likely to result in bowel ischemia. Nonetheless, any patient with recurrent intussusception should be evaluated to assess location and for the presence of a pathologic lead point. We report a patient with recurrent small bowel into small bowel intussusception who underwent a comprehensive evaluation that revealed lymphoid hyperplasia in the absence of a pathologic lead point. His symptoms resolved after a dose of oral dexamethasone.
RESUMEN
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.
RESUMEN
OBJECTIVE: Crohn's disease (CD) is heterogeneous, and proximal involvement in the small bowel (SB) is associated with worse outcomes. Nonetheless, studies on the impact of duodenal and jejunal lesions in SB CD are limited. This study aimed to investigate the clinical characteristics and outcomes of individuals diagnosed with SB CD, comparing those with and without proximal inflammation. METHODS: A cohort of 53 treatment-naive SB CD patients that underwent Capsule Endoscopy at diagnosis were retrospectively selected. The inflammatory activity was quantified using the Lewis Score for each SB tertile. RESULTS: Thirty-seven (69.8%) patients displayed inflammatory activity in the first and/or second tertile together with third tertile involvement (Proximal+T3 group). Sixteen (30.2%) had inflammation in the third tertile only (T3 group). Individuals in the Proximal+T3 group had a higher risk for moderate-to-severe inflammation (OR 4.93, 95% CI: 1.3-18.3, p=0.013). A subgroup analysis for those with mild inflammatory activity showed that individuals in the Proximal+T3 group initiated biologic drugs more often (OR 11, 95% CI: 1.1-109.7, p=0.036). CONCLUSION: Proximal SB lesions are associated with increased inflammatory activity, necessitating more frequent use of biologics in patients with mild disease. Early detection of proximal SB CD with Capsule Endoscopy may contribute to timely treatment.
RESUMEN
AIMS: Inflammatory bowel disease-associated colorectal carcinomas are known to have different morphology, immunoprofile, and genetic findings from sporadic colorectal carcinomas; however, little is known for Crohn's disease-associated small bowel neoplasms (CD-SBNs). Cadherin 17 is a useful biomarker of adenocarcinomas with intestinal phenotype and recently reported as an ideal target for chimeric antigen receptor T-cells (CAR-T) therapy for gastrointestinal carcinoma. Claudin 18 is a cell adhesion protein, and Claudin18 isoform 2 (CLDN18.2) is frequently expressed at high levels in gastric-type adenocarcinoma. Zolbetuximab, a targeted monoclonal antibody, has been developed for CLDN18.2-positive gastroesophageal adenocarcinoma. We examined a series of CD-SBNs for both Cadherin 17 and Claudin 18, and also hypothesized that expression of Claudin 18 was associated with gastric phenotype. METHODS AND RESULTS: We performed histological and immunohistochemical examinations on 25 CD-SBNs. Most of adenocarcinomas showed tubular morphology as seen in gastric carcinomas, whereas a subset of dysplasia was morphologically similar to that of the large bowel. Cadherin17 and Claudin 18 expression was identified in 93% and 57% CD-associated adenocarcinomas respectively. In Cadherin 17-positive CD-SBNs, frequent MUC5AC, MUC6, and Claudin18 expression was identified (61%, 57%, and 57%, respectively). Claudin 18-positive CD-SBNs showed significantly more MUC5AC and MUC6 expression than Claudin 18-negative CD-SBNs (P = 0.005, < 0.001 respectively). CONCLUSION: In CD-associated small bowel adenocarcinomas, Cadherin 17 expression was frequently retained and Claudin 18 was frequently co-expressed. Claudin 18 had a positive correlation with the expression of gastric mucins. These results suggest that CD-associated small bowel adenocarcinomas may be candidates for Cadherin 17- and Claudin 18-targeted immunotherapies.
RESUMEN
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.
