BACKGROUND: Acute small bowel obstruction (SBO) is a common surgical emergency. The study aims to provide a comprehensive clinical-epidemiological description of SBO in adults at a tertiary care center in western India.
METHODS: This hospital-based cross-sectional study was conducted from July 2020 to June 2022 and enrolled 88 SBO patients requiring surgical intervention. After adequately resuscitating the patients, various surgical procedures were performed based on the intraoperative conditions of the bowel. Patients were assessed postoperatively for the duration of their hospital stay, postoperative complications, and surgical recovery.
RESULTS: There was a male preponderance (n=55), with a median age of 50 (18-90) years. Abdominal discomfort was the most frequent symptom, necessitating a hospital visit (97.9%, n= 86), followed by nausea (85.2%, n= 75), constipation (78.1%, n=69), and abdominal distension (51.1%, n=45). Ileal strictures (18.2%, n=16) were the most common etiology, followed by postoperative adhesions (14.8%, n=13) and bands (13.6%, n=12), of which 76.4% (n=9) had past surgical history. Resection and anastomosis were the most frequently performed surgical interventions in this study (36.4%, n=32), followed by stoma creation (27.3%, n=24) and adhesiolysis (17%, n=15). The postoperative 30-day mortality of 11.36% (n=10) was noted, which could be ascribed to the elderly population with comorbidity, postoperative complications, and who required extended stay in the critical care unit.
CONCLUSIONS: Benign ileal stricture was the most common cause of acute SBO in the emergency. Prompt and timely diagnosis combined with a multidisciplinary approach and effective management can improve outcomes and reduce morbidity and mortality in adult patients with SBO.

Small bowel obstruction is a frequent medical condition with various causes, the most common being postoperative adhesions, volvulus, intussusception, hernias, and tumors. A bezoar-induced blockage of the small intestine is a rare condition that accounts for approximately 4% of all small bowel obstruction cases. Herein, we present the case report of a 71-year-old patient with diffuse abdominal pain caused by a small bowel obstruction due to a calcified bezoar (bezoar egg) resulting from a post-radiation intestinal stricture. The patient underwent a small bowel excision with the extraction of the bezoar, after which a full recovery was made.

The incidence of tuberculosis (TB) worldwide is still significantly high, with India contributing a high global TB burden. This case study features a 49-year-old male who had complaints of pain and abdominal distention for one and a half months. An erect abdominal radiograph showed features suggesting small bowel obstruction. Contrast-enhanced computed tomography (CT) of the abdomen was done. It showed multiple strictures involving the distal jejunum and ileum, causing small bowel obstruction. There was mesenteric and retroperitoneal lymphadenopathy with central necrosis and ascites. The patient was operated on for a small bowel obstruction. The resected intestine showed four strictures, tiny nodules on the serosal surface, and many enlarged lymph nodes. Representative tissue from these areas showed the typical picture of multiple caseating granulomas and fibrosis. Ziehl-Neelsen (ZN) staining highlighted the acid-fast bacilli (AFB). The suspicion index for intestinal tuberculosis (ITB) should be kept high while evaluating patients with intestinal obstruction presenting in endemic areas and high-risk populations, such as HIV-infected, undernourished, immunocompromised, and those with diabetes, smoking, and alcohol addiction.

A 44-year-old man presented to our hospital with lower gastrointestinal bleeding. We performed balloon-assisted enteroscopy, which revealed diverticulum and stricture at the ileum. The patient underwent segmental small bowel resection and diagnosed with Meckel\'s diverticulum. We should keep in mind the possibility of intestinal stricture due to Meckel\'s diverticulum.

BACKGROUND: Patients with Crohn\'s disease can develop intestinal strictures, containing various degrees of inflammation and fibrosis. Differentiation of the main component of a stricturing lesion is the key for defining the therapeutic management.
OBJECTIVE: We assessed for the first time the accuracy of magnetic resonance elastography in detecting intestinal fibrosis and predicting clinical course in patients with Crohn\'s disease.
METHODS: This was a prospective study of adult patients with Crohn\'s disease and magnetic resonance imaging examination, including magnetic resonance elastography, between April 2019 and February 2020. The association between the bowel stiffness value and the degree of fibrosis was evaluated. The relationship between the stiffness value and the occurrence of clinical events was also investigated.
RESULTS: A total of 69 patients were included. The stiffness value measured by magnetic resonance elastography was correlated with the degree of fibrosis (p < 0.001). A bowel stiffness ≥ 3.57 kPa predicted the occurrence of clinical events with an area under the curve of 0.82 (95% CI 0.71-0.93). Bowel stiffness ≥ 3.57 kPa was associated with an increased risk of clinical events (p < 0.0001).
CONCLUSIONS: In Crohn\'s disease, magnetic resonance elastography is a reliable tool for detecting intestinal fibrosis and predicting a worse disease outcome.

UNASSIGNED: Self-expandable metal stents are used for malignant duodenal obstruction. Outcomes between stents placed above and below the papilla of Vater differ, and no study has investigated these differences. We evaluated the efficacy and adverse events of stent placement in these two locations and reported our experience with self-expandable metal stent placement in patients.
UNASSIGNED: We retrospectively analyzed the data of patients with unresectable metastatic cancers (n = 101), who underwent successful duodenal self-expandable metal stent placement between 2008 and 2018. Patients were divided into above and below the papilla of Vater groups. Patient demographics, technical and clinical outcomes, post-procedural morbidity, and stent patency were analyzed.
UNASSIGNED: Overall, 71 and 30 patients had intestinal obstruction above (including the papilla itself) and below the papilla of Vater and underwent successful stenting. Common bile duct obstruction was more common in the above-papilla group. Procedure time was similar between the groups, if an appropriate endoscope could facilitate stent placement in the below-papilla group. Both groups achieved symptomatic relief. Median stent patency duration was not significantly different between the groups; three patients had severe gastrointestinal bleeding due to postoperative vascular-enteric fistula.
UNASSIGNED: Self-expandable metal stents can effectively relieve symptoms of duodenal obstructions located above and below the papilla of Vater. Duodenoscopes could facilitate stent placement if the obstruction is located below the papilla of Vater; if gastrointestinal bleeding occurs postoperatively, the possibility of vascular-enteric fistula formation should be considered.

A 69-year-old man was admitted to a hospital with complaints of abdominal pain. Computed tomography showed hepatic portal venous gas and pneumatosis cystoides intestinalis. Conservative treatment was effective; however, after discharge, he developed complaints of vomiting. Fluoroscopic enteroclysis revealed a stricture in the jejunum necessitating admission to our hospital. Transoral balloon-assisted enteroscopy showed a circumferential ulcer with a stricture. The stricture was surgically resected, and a histopathological examination was consistent with ischemic enteritis. Stenotic ischemic enteritis should be considered among the differential diagnoses in a patient presenting with hepatic portal venous gas and pneumatosis cystoides intestinalis showing small intestinal obstruction.

BACKGROUND: Small bowel obstruction (SBO) in the virgin abdomen usually requires operative intervention. Intestinal stenosis of Garré is a rare and frequently missed cause of SBO following hernia repair.
METHODS: We describe a case of intestinal stenosis of Garré and provide a comprehensive review of the literature. Statistical analysis was performed using IBM SPSS Statistics V.22 software and included descriptive analysis.
RESULTS: Most males developed a delayed stricture following an inguinal hernia repair (93.3%). 84.6% of females, on the other hand, developed intestinal stenosis following repair of a femoral hernia. 87.5% of strictures developed on the right side. The timing of development of a bowel obstruction is very variable and ranges from 5days to 22 years. 22 patients (68.8%), however, presented with an obstruction within 5 months of hernia repair.
CONCLUSIONS: Intestinal stenosis of Garré is an under-reported cause of delayed stricture formation.It is most common following right inguinal hernia repair in men and right femoral hernia repair in women.

BACKGROUND: Crohn\'s disease (CD) is frequently complicated by intestinal strictures, which are commonly treated by endoscopic balloon dilation (EBD). However, available data on this area of treatment is limited. The aim of this study was to depict the heterogeneity of endoscopic management of CD-associated strictures among international CD specialists to identify common treatment standards.
METHODS: IBD experts of the International Organization for the Study of Inflammatory Bowel Disease (IOIBD), the European Crohn\'s and Colitis Organization (ECCO), and from the Prospective Value In IBD trials (PROVIT) completed a web-based questionnaire to evaluate their endoscopic experience, practice setting, and number of EBDs performed annually. Additionally, two case scenarios and technical practice parameters were investigated.
RESULTS: A total of 126 subjects from 15 countries completed the survey. The maximal length of dilated stricture was 4.5 ± 1.7 cm. The most commonly used maximal balloon size was graded as 15-18 mm. While 87.2 % of the participants favored EBD for anastomotic strictures, only 58.6 % did so in the case of naïve strictures. Only 35.7 % of physicians dilated actively inflamed strictures. Interventional endoscopists were more likely to dilate only clinically symptomatic strictures (p = 0.046). Surgeons favored surgical treatment of de novo ileocecal strictures compared to gastroenterologists (p = 0.026), reported a shorter stricture length being amendable by EBD (p = 0.045), and more frequently used concomitant therapies (p = 0.001). Operator experience increased the likelihood of EBD use in actively inflamed strictures (p = 0.002), maximum length of stricture, and maximum balloon size (p = 0.001).
CONCLUSIONS: EBD is a widely used treatment approach for stricturing CD. Individual approaches differ significantly based on background of the operator, experience level, and practice setting.
