## Direct answer

Three routes reach the adrenal gland and the choice is dictated by tumour size, suspicion of malignancy, laterality and the patient's surgical history: laparoscopic lateral transperitoneal adrenalectomy is the workhorse (right side — mobilise the liver and divide the short adrenal vein draining directly into the inferior vena cava; left side — take the inferior phrenic and central adrenal branches off the left renal vein after mobilising spleen and pancreas tail); posterior retroperitoneoscopic adrenalectomy (prone, directly onto the gland) suits bilateral disease, smaller tumours and patients with previous abdominal surgery; and open approaches — the posterior lumbodorsal (Young's) incision, the anterior transperitoneal, and the thoracoabdominal incision — are reserved for large adrenal carcinomas, vascular invasion (inferior vena cava tumour thrombus) and occasional giant phaeochromocytomas. Laparoscopic adrenalectomy is standard for benign lesions up to about 10–12 cm because it shortens stay and morbidity without compromising oncological outcomes in appropriately selected disease.

## What you must remember

- Anatomy that decides the operation: right adrenal vein is short and enters the inferior vena cava directly (the dangerous clip — avulsion bleeds catastrophically); left adrenal vein drains to the left renal vein; arterial supply is segmental from inferior phrenic, aorta and renal artery branches, coagulated or clipped piecemeal.
- Laparoscopic lateral transperitoneal (most common worldwide): right — patient left lateral decubitus, ports below the costal margin, liver retraction, peritoneal reflection divided along the inferior vena cava, early central vein control; left — mobilise the splenic flexure and spleen (or pancreas tail) medially, vein control at the renal vein, gland removed in a retrieval bag.
- Posterior retroperitoneoscopic (prone jackknife): direct approach through Gerota's fat — no abdominal entry, ideal for bilateral tumours (reposition-free staged same anaesthetic), previous upper abdominal surgery, and smaller lesions; limitations are working space (obesity and tumours over about 6–8 cm) and the learning curve.
- Open posterior lumbodorsal (Young's) approach: through the bed of the 11th or 12th rib without entering the pleura or peritoneum — historically for bilateral hyperplasia; limited exposure above, so reserved for small glands.
- Open anterior (transperitoneal midline or subcostal): access to both glands, great vessels and the whole abdomen — the choice for adrenocortical carcinoma, large tumours over 10–12 cm, suspected malignancy, and IVC tumour thrombus (with vascular control and possible cardiac bypass for retrohepatic extension); thoracoabdominal extension for the largest right upper quadrant tumours.
- Size and malignancy logic: laparoscopic resection is acceptable for tumours up to roughly 10–12 cm in experienced hands, but breach of capsule or inability to maintain oncological principles mandates open conversion; incidentally found lesions over 4 cm (especially over 6 cm) raise carcinoma probability — operate, and if carcinoma is suspected, plan open en bloc resection with adjacent organ resection as needed.
- Partial (cortical-sparing) adrenalectomy: for bilateral phaeochromocytoma in MEN2/VHL and hereditary bilateral disease, and selected unilateral aldosterone-producing adenomas — preserving cortical function avoids lifelong steroid dependence; frozen control of the vein and a rim of cortex is left.
- Perioperative pearls that general surgical trainees must own: phaeochromocytoma comes alpha-blocked and volume-replete (beta-blocker added only after alpha-blockade), with minimal tumour handling and vasopressor readiness; cortisol-secreting lesions need intraoperative and tapering postoperative steroid cover for a suppressed contralateral axis; aldosteronomas need potassium correction and postoperative mineralocorticoid escape watch.
- Complications: bleeding from the adrenal vein/IVC (the commonest cause of conversion), pancreatic and splenic injury on the left, liver retraction injury and duodenal injury on the right, pleural entry in posterior/open approaches, and port-site or incisional issues.

## A worked example

A 42-year-old woman with a 3 cm right aldosterone-producing adenoma (resistant hypertension, hypokalaemia, adrenal vein sampling lateralising right) is offered surgery: a laparoscopic right adrenalectomy — lateral transperitoneal in most Indian centres, or posterior retroperitoneoscopic where available (she has no previous surgery, and either is defensible). Sequence: potassium repleted preoperatively; right lobe of liver retracted, peritoneum incised along the IVC, gland mobilised from medial to lateral, short central vein clipped flush with the IVC (a prettily placed clip is the operation's signature), arteries taken piecemeal, specimen bagged. Contrast the decision tree around her: the same-sized lesion in a man with a 9 cm left adrenal mass with irregular margins and radiological capsular breach (suspected carcinoma) gets an open anterior approach with en bloc resection of the tumour with surrounding fat ± kidney and distal pancreas as indicated — laparoscopy risks rupture and seeding. A woman with bilateral phaeochromocytomas in MEN2 gets posterior retroperitoneoscopic bilateral excision (or cortical-sparing partial excision) after alpha-blockade. A recurrent Cushing adenoma after prior upper abdominal surgery gets the posterior route because the abdomen is hostile. Each branch is decided by size, suspicion, laterality and surgical history — not by surgeon habit alone.

## Where students slip

The first slip is offering laparoscopy for everything: suspected adrenocortical carcinoma with IVC involvement is an open, vascular-controlled operation, and saying so earns the mark. The second is anatomical — the right adrenal vein into the IVC (short, high-pressure) versus the left into the renal vein; this single fact explains why right-sided bleeding converts more often. The third is forgetting the endocrine preparation that precedes any approach: unprepared phaeochromocytoma is lethal regardless of how elegant the access is, and the steroid-cover principle for Cushing adenomas (suppressed contralateral gland) is a standing exam question.

## Frequently asked questions

### Which approach is standard for benign adrenal tumours?
Laparoscopic adrenalectomy — lateral transperitoneal most commonly, or posterior retroperitoneoscopic for bilateral disease, smaller tumours and hostile abdomens.

### What are the indications for open adrenalectomy?
Suspected or confirmed adrenocortical carcinoma, tumours generally over 10–12 cm, inferior vena cava tumour thrombus, and local invasion requiring en bloc adjacent organ resection.

### Why is the right adrenal vein the dangerous step?
It is short and drains directly into the inferior vena cava — avulsion or slippage causes torrential venous haemorrhage, the commonest reason for conversion on the right.

### When is posterior retroperitoneoscopic access preferred?
For bilateral tumours (both glands in one anaesthetic without repositioning), previous upper abdominal surgery, and smaller lesions — limited by working space in obesity and larger tumours.

### What is cortical-sparing (partial) adrenalectomy and when is it used?
Excision of the tumour leaving a vascularised rim of adrenal cortex — for bilateral phaeochromocytoma in MEN2/VHL and selected aldosteronomas, avoiding lifelong steroid dependence.
