The correct answer is  PHARYNGEAL POUCH Also called hypopharyngeal diveiculum or Zenker's diveiculum, it is a pulsion diveiculum where pharyngeal mucosa herniates through the Killian's dehiscence--a weak area between two pas of the inferior constrictor. TREATMENT :- 1. Excision of pouch and cricopharyngeal myotomy. This is done through cervical approach. 2. Dohlman's procedure. The paition wall between the oesophagus and the pouch is divided by diathermy through an endoscope. This is done in poor risk debilitated patients. 3. Endoscopic laser treatment. It is similar to Dohlman's procedure. Paition between the pouch and oesophagus is divided by CO2 laser using operating microscope. Ref:- Dhingra; pg num:-274,275
