Background: This study aimed to create a nomogram for predicting the recurrence of small bowel obstruction (SBO) after gastrectomy in patients with gastric cancer (GC) in order to provide better guidance for its diagnosis and treatment.
Methods: A total of 173 patients undergone gastrectomy and developed SBO from January 2015 to October 2022 were admitted into this case-control study. The risk factors of postoperative recurrent SBO were analyzed by univariate and multivariate regression, and a nomogram for predicting the recurrent SBO after gastrectomy was developed using R Studio.
Results: Thirty-nine cases of postoperative recurrent SBO occurred among the 173 GC patients who underwent radical gastrectomy, and the percentage of recurrent SBO was 22.54% (39/173). Age [odds ratio (OR) = 0.938, p = 0.026], WBC count (OR = 1.547, p < 0.001), tumor size (OR = 1.383, p = 0.024), postoperative metastasis (OR = 11.792, p = 0.030), and the interval from gastrectomy to first SBO (OR = 1.057, p < 0.001) were all identified as independent risk factors for postoperative recurrent SBO by logistic regression analysis. The receiver operating characteristic curve, the calibration curve, the model consistency index, and the decision curve analysis showed that the nomogram had good predictive performance.
Conclusion: Based on these factors, we created a nomogram to predict the occurrence of postoperative recurrent SBO. This novel nomogram could serve as a crucial early warning indicator that would guide doctors to make informed decisions while managing patients with gastric cancer.

Background: Recognizing factors that predict non-operative management (NOM) failure for patients with small bowel obstruction (SBO) aids in limiting surgical intervention when needed. This study investigated the predictive factors for NOM failure in SBO patients in a resource-limited setting.
Material And Method: A retrospective study included 165 patients who were diagnosed with SBO and were admitted and managed at Althora General Hospital, IBB, Yemen, from April 2022 to March 2024.

Introduction: Growing evidence supports the success of nonoperative management (NOM) for pediatric adhesive small bowel obstruction (A-SBO). However, there is concern that patients with nonadhesive SBO (NA-SBO) will have repeat episodes of SBO if not treated with surgery upfront. We examined whether NOM of NA-SBO at initial presentation was associated with increased risk of recurrent SBO.

Small bowel obstruction (SBO) remains the most common diagnosis encountered by general surgeons, with 70% of cases related to adhesions from previous abdominal surgeries. Less common etiologies include Crohn's disease, gallstone ileus, and Meckel's diverticulum (MD). While MD is the most common congenital anomaly of the gastrointestinal tract, it is less frequently considered as a cause in adults.

BACKGROUND Encapsulating peritoneal sclerosis (EPS) is a life-threatening complication of peritoneal dialysis (PD). It is characterized by a fibrous membrane partially or totally encasing the small bowel and is a rare cause of small bowel obstruction (SBO). Here we present a case of a young woman with a history of PD presenting with SBO due to EPS.

Appendiceal carcinoma, a rare malignancy comprising less than 1% of gastrointestinal cancers, often presents diagnostic challenges due to its atypical symptoms. This report details a 68-year-old female with a history of severe anemia, gastrointestinal bleeding, and persistent abdominal symptoms, ultimately diagnosed with chronic small bowel obstruction caused by an appendiceal adenocarcinoma. Despite initial treatment for Helicobacter pylori-induced gastritis, her symptoms persisted, prompting further imaging that revealed a narrowed small bowel segment.
