Severe small intestinal bacterial overgrowth syndrome after jejunal feeding requiring surgical intervention: a case report and review of the literature.

BMC Gastroenterol 2022 Jun 20;22(1):300. Epub 2022 Jun 20.

Department of Surgery, Valleywise Health Medical Center, Phoenix, AZ, USA.

Background: Small intestinal bacterial overgrowth (SIBO) is a condition of unknown prevalence characterized by an excessive amount of bacteria in the small bowel, typically resulting in vague gastrointestinal symptoms with bloating being most commonly reported. Here we describe a severe case of SIBO leading to small bowel necrosis requiring surgical intervention.

Case Presentation: A 55-year-old Hispanic female with gastric outlet obstruction secondary to a newly diagnosed gastric adenocarcinoma, receiving neoadjuvant chemotherapy, developed bloody gastrostomy output and rapidly progressing nausea and abdominal distention 3 days after jejunostomy tube placement and initiation of jejunal enteral nutrition.

Pneumatosis cystoides intestinalis accompanied by schistosomiasis: a case report.

J Int Med Res 2022 Jun;50(6):3000605221105160

Department of Pathology, Minhang Hospital, Fudan University, Shanghai, P. R. China.

Pneumatosis cystoides intestinalis (PCI) is a rare disease that most frequently occurs in the large and small intestine and has no obvious clinical symptoms. The main pathological feature is the presence of air-filled cysts in the intestinal submucosa, intermuscular wall, and subserous membrane. Conservative treatment is the first choice when no serious complications are present, whereas timely surgical treatment is needed for serious and life-threatening complications. Read More

Unusual computed tomography findings of gas in the superior mesenteric artery system with no signs of porto-mesenteric venous gas in a case of acute mesenteric ischemia.

Radiol Case Rep 2022 Jul 20;17(7):2568-2572. Epub 2022 May 20.

Department of Radiological Sciences, Oncology and Pathology, "Sapienza" University of Rome - I.C.O.T. Hospital, Via Franco Faggiana, 1668, 04100, Latina, Italy.

Acute Mesenteric Ischemia (AMI) is a rare life-threatening entity caused by sudden interruption of the blood supply to a segment of the bowel due to impairment of mesenteric arterial blood flow or venous drainage. Clinical presentation varies according to the time course of vascular occlusion. Contrast-enhanced Computed Tomography (CT) of the abdomen represents the main diagnostic test for AMI diagnosis, enabling fast and excellent evaluation of the intestine, mesenteric vasculature, and other ancillary characteristics of AMI.

An Update on Acute Mesenteric Ischemia.

Can Assoc Radiol J 2022 May 11:8465371221094280. Epub 2022 May 11.

Department of Diagnostic Radiology, 8664University of Manitoba, Winnipeg, MB, Canada.

Acute mesenteric ischemia (AMI) is an uncommon yet highly lethal cause of acute abdomen in the emergency setting. Computed tomography (CT) imaging, in particular a biphasic protocol consisting of angiographic and venous phase scans, is widely used to corroborate non-specific clinical findings when suspicions of AMI are high. Techniques such as low kilovoltage peak scanning, dual energy acquisition, or a combined arterial/enteric phase can improve iodine conspicuity and evaluation of bowel enhancement. Read More

Pneumatosis Intestinalis of the Colon and Greater Omentum following Small Bowel Resection.

Case Rep Surg 2022 16;2022:2670244. Epub 2022 Apr 16.

Discipline of Surgery, Faculty of Medicine, Memorial University of Newfoundland, St. John's, NL, Canada A1B 3V6.

Introduction: Pneumatosis intestinalis (PI) is a condition of gas collection within the bowel wall that can represent either a benign clinical finding or a forerunner to potential gastrointestinal catastrophe. As a potentially sinister discovery typically first detected on radiographic imaging, clinicians need to astutely assess the need for additional urgent medical or surgical management in these patients. Apart from portal venous gas, PI outside of the bowel wall is an extremely rare entity that is poorly described. Read More

Pneumatosis Cystoides Intestinalis: A Benign Cause of Pneumoperitoneum.

J Med Cases 2022 Apr 25;13(4):188-191. Epub 2022 Mar 25.

South East Regional Hospital, Bega, NSW, Australia.

Pneumatosis cystoides intestinalis (PCI) is an uncommon condition where cyst-like locules of gas are present in the submucosa or subserosa of the gastrointestinal tract. The majority of cases are benign and are associated with drugs such as chemotherapy agents or conditions including chronic obstructive airways disease. We present the case of PCI resulting in pneumoperitoneum in a 72-year-old male patient on chemotherapy for esophageal adenocarcinoma. Read More

Pneumatosis cystoides intestinalis associated with etoposide in hematological malignancies: a case report and a literature review.

BMC Gastroenterol 2022 Mar 28;22(1):150. Epub 2022 Mar 28.

Department of Critical Care Medicine, West China Hospital, Sichuan University, Chengdu, 610041, Sichuan Province, People's Republic of China.

Pneumatosis cystoides intestinalis (PCI) is a rare condition characterized by the presence of air collection within the subserosa and/or submucosa of the gastrointestinal wall. Due to the lack of specific symptoms, PCI is likely to be misdiagnosed or missed without the use of imaging techniques or gastrointestinal endoscopy. Here, we report a patient who complained of abdominal distention and constipation after chemotherapy for hematological malignancies, and was diagnosed with secondary PCI via computed tomography (CT) and exploratory laparotomy.

Gastric Pneumatosis with Portal Venous Gas can be Treated Non-operatively: A Retrospective Multi-institutional Study.

World J Surg 2022 04 6;46(4):784-790. Epub 2022 Feb 6.

Service de chirurgie digestive et cancérologique, CHU Nord Saint Etienne, Avenue Albert Raimond, 42270, Saint-Priest-en-Jarez, France.

Background: Gastric pneumatosis (GP) is a rare radiologic finding with an unpredictable prognosis. The aim of this study was to identify mortality risk factors from patients presenting with GP on computed tomography (CT), and to develop a model which would allow us to predict which patients would benefit most from operative management.

Methods: Between 2010 and 2020, all CT-scan reports in four tertiary centers were searched for the following terms: "gastric pneumatosis," "intramural gastric air" or "emphysematous gastritis. Read More

A problem at any age: a case report of congenital malrotation with bowel ischemia in an 84-year-old.

BMC Surg 2022 Jan 29;22(1):35. Epub 2022 Jan 29.

Department of Surgery, California Pacific Medical Center, San Francisco, CA, USA.

Background: Malrotation with bowel ischemia is classically thought of as a disease of infants. However, the true prevalence of malrotation in both the pediatric and adult population is unknown due to the unclear number of asymptomatic patients.

Case Presentation: A previously healthy 84-year-old man with no prior abdominal surgeries presented with an acute abdomen and was found on CT to have small bowel located in the right hemiabdomen and an abnormal SMA-SMV relationship suggestive of intestinal malrotation, as well as pneumatosis intestinalis.
