Stomach

Answer c -

In Billroth 2 surgery, afferent limb obstruction is more common

In Billroth 1 reconstruction The remnant is anastomosed  to the duodenum

In Billroth 2 duodenum stump is closed and stomach is anastomosed to the jejunum limb

Advantages of Billroth 1 

1. More Physiological as normal GI continuity is maintained
2. No problem of afferent and efferent limb
3. Future procedures like endoscopy and ERCP can be done
4. Reduced chance of gastric carcinoma in remnant stomach as compared to Billroth 2  ( SKF page 682) 

In surgery for benign gastric ulcers, Billroth I reconstruction is the preferred choice.

Billroth II surgery has problems of

1. Retained antrum syndrome
2. Afferent loop obstruction
3. Duodenal stump leak (1-3%)

Billroth 2 surgery is done when there is

1. Inadequate mobility of the duodenum

2. Scarring of duodenum

Complications of gastric surgery
Complications of gastrectomy

1. Nutritional and weight loss - Iron deficiency, Copper deficiency, Vit B12 , Anemia
2. Delayed gastric emptying
3. Roux statsis- Seen in roux en y loops-  Pain, nausea, vomiting, abdominal bloating
4. Cholelithiasis-  Higher incidence in roux en y reconstruction as compared to B1 and B 2 gastrectomy
5. Recurrent ulceration

Complications of Billroth 2 surgery

1. Dumping syndrome Dumping symptoms have been reported in up to 70% of Billroth II patients and up to 75% of patients after RYGBP
   for obesity.
2. Afferent loop obstruction - It can be minimized by keeping the length of afferent loop less than 20 cm and using a retrocloic approach.
3. Bile reflux gastritis - More common with billroth I and billroth 2 surgery, incidence is decreasing after the use roux en y anastomosis
