Management challenges in a patient presenting with acute mesenteric ischaemia

Area of Science:

• Gastroenterology
• Vascular Surgery
• Surgical Nutrition

Background:

• Superior mesenteric artery thrombosis (SMAT) is a critical condition causing bowel ischemia.
• Acute mesenteric ischemia necessitates prompt diagnosis and surgical intervention.
• Short bowel syndrome (SBS) is a potential complication following extensive bowel resection.

Purpose of the Study:

• To present a case of SMAT resulting in extensive small bowel resection and subsequent SBS.
• To highlight the complexities in managing SBS, including surgical, nutritional, and monitoring aspects.
• To underscore the importance of a multidisciplinary approach in optimizing outcomes for SBS patients.

Main Methods:

• A 60s male presented with acute abdominal symptoms.
• Contrast-enhanced CT confirmed SMAT with bowel ischemia.
• Exploratory laparotomy revealed gangrenous small bowel (323 cm), followed by resection and double-barrel jejuno-ileostomy.
• Postoperative management included total parenteral nutrition, oral supplementation, and refeeding.
• Surgical restoration of bowel continuity was performed after initial stabilization for SBS.
• Refeeding syndrome was managed with micronutrient supplementation.

Main Results:

• The patient developed short bowel syndrome post-initial surgery.
• Restoration of bowel continuity was successfully performed.
• Refeeding syndrome was effectively managed with micronutrient supplementation.
• The case highlights challenges in surgical and nutritional management of SBS.

Conclusions:

• Effective management of SMAT-induced SBS requires timely surgical intervention and meticulous postoperative care.
• Appropriate nutritional support, including management of refeeding syndrome, is crucial for SBS patients.
• This case emphasizes the need for a comprehensive strategy to improve outcomes in complex gastrointestinal surgical cases.
