Comprehensive small intestine surgical care — management of small bowel obstruction, Crohn's disease complications, small intestinal tumours, enterocutaneous fistulae, and mesenteric ischaemia — by Dr. Hamikchandra Patel at Shaleen Multi Speciality Hospital, Sola, Ahmedabad.
Understanding the Small Intestine
The small intestine — approximately 6 metres long — is the primary site for nutrient absorption. It consists of three segments: the duodenum (connected to the stomach), the jejunum, and the ileum (connecting to the large intestine). The small intestine processes most of digestion: proteins, fats, and carbohydrates are broken down and absorbed along its enormous surface area, augmented by millions of finger-like projections called villi.
Small intestine disorders span a wide spectrum — from common and acutely life-threatening (small bowel obstruction, mesenteric ischaemia) to chronic and complex (Crohn's disease, short bowel syndrome, enterocutaneous fistulae) to neoplastic (carcinoid tumours, GIST, lymphoma, adenocarcinoma). The management of small intestinal disease requires the expertise of a specialist surgical gastroenterologist — someone trained not just in the technical aspects of bowel surgery but in the complex nutritional, inflammatory, and oncological dimensions of small bowel disease.
Dr. Hamikchandra Patel's Fellowship in Surgical Gastroenterology and Minimal Access Surgery provides this specialised background for managing small intestine disorders in Ahmedabad.
Complete small bowel obstruction — from adhesions, hernia, volvulus, or tumour — is a surgical emergency. Without prompt relief of obstruction, the bowel's blood supply may be compromised (strangulation), leading to bowel gangrene, perforation, and peritonitis. Urgent surgical evaluation is essential for any suspected obstruction.
Most Crohn's disease is managed medically. Surgery is indicated for complications: strictures causing obstruction, internal or external fistulae, abscesses, and segments refractory to medical treatment. Surgery controls complications without claiming to cure the disease — Crohn's can affect any remaining bowel segment.
Capsule endoscopy and balloon-assisted enteroscopy allow direct visualisation of the small intestinal lining — diagnosing Crohn's, tumours, obscure GI bleeding, and coeliac disease complications that standard upper and lower endoscopy cannot reach.
Small Intestine Conditions We Treat
Expert diagnosis and surgical management for the complete spectrum of small bowel disorders.
Blockage of the small intestine — most commonly from adhesions (post-operative scar tissue), incarcerated hernia, volvulus, or tumour. Mild obstruction may resolve with conservative management; complete or strangulated obstruction requires urgent laparoscopic or open surgical relief.
Transmural inflammatory disease affecting any segment of the GI tract — most commonly the terminal ileum. Complications requiring surgery include: fibrostenotic strictures causing obstruction, fistulae (enteroenteric, enterovesical, enterocutaneous), abscesses, and perforation.
Rare but important — gastrointestinal stromal tumours (GIST), carcinoid tumours, small bowel adenocarcinoma, and lymphoma. Often diagnosed late due to vague symptoms. Surgical resection is primary treatment for GIST and carcinoid; medical therapy is central for lymphoma.
Acute obstruction of mesenteric blood supply — from arterial embolism, thrombosis, or venous thrombosis — causes rapid bowel infarction. A catastrophic surgical emergency requiring immediate intervention. Chronic mesenteric ischaemia presents with postprandial pain and weight loss (intestinal angina).
Surgical Procedures
Laparoscopic division of adhesive bands causing obstruction — restoring intestinal patency with minimal operative trauma. Resection of infarcted or tumour-bearing bowel segments with primary anastomosis (re-joining bowel ends) — performed laparoscopically where feasible, open in complex or emergency settings.
Strictureplasty — widening the narrowed bowel without removing it — preserves intestinal length in Crohn's patients with multiple strictures. Ileocaecal resection removes the terminal ileum and caecum — the most commonly affected Crohn's segment — with anastomosis restoring continuity.
For strangulated obstruction, mesenteric ischaemia, perforation, or Meckel's diverticulum complications — urgent surgical intervention including bowel resection with primary anastomosis or temporary stoma creation. Mesenteric revascularisation for salvageable acute mesenteric ischaemia.
Treatment Process
CT abdomen with contrast is the most important investigation for small bowel disorders — identifying obstruction site and level, assessing bowel viability (wall thickening, pneumatosis), and detecting tumours, fistulae, or abscesses. Plain X-ray abdomen for initial obstruction screening. MRI enterography for Crohn's disease assessment.
Partial obstruction from adhesions: NG tube decompression, IV fluids, nil by mouth for 24–48 hours — many resolve spontaneously. Complete obstruction, strangulation, or peritonitis: immediate surgical intervention. Crohn's abscess: CT-guided drainage before elective surgical resection.
Adhesiolysis, bowel resection, strictureplasty, or vascular surgery as indicated. Intraoperative assessment of all small bowel for ischaemia or secondary pathology. Anastomosis performed where safe; stoma created in contaminated or ischaemic fields for safety.
Small intestinal surgery may temporarily impair absorption. Early enteral nutrition (feeding through a nasojejunal tube or jejunostomy) is initiated promptly. Parenteral nutrition for complex cases. Dietitian involvement for long-term nutritional planning, particularly in short bowel syndrome.
For Crohn's: monitoring for recurrence with ileocolonoscopy at 6–12 months post-operatively; medical maintenance therapy with gastroenterology. For tumours: oncology-directed surveillance imaging and tumour markers. Adhesion-related obstruction recurrence risk counselling and lifestyle advice.
