Postoperative management: The nasogastric tube will be removed on the 3rd postoperative day. Jejunostomy trial feed will be started intestinal activity will appear. If there is no obvious leak, bedside test feeding with water will be done on the 5th postoperative day. If bedside test feeding shows no leak, oral feeding will be started gradually with water, banana, curds and soft diet. A contrast study will be done on the 7th postoperative day unless there is an obvious anastomotic leak. The neck drain will be removed after the contrast study. If a leak is identified, the cervical wound will be opened to establish external drainage of any cervical abscess and anastomotic fistulae. Regular dressing with normal saline soaked gauze will be done. If there is no clinical leak but the contrast study shows a contained leak (type 1 leak), patients will be managed conservatively without opening the cervical wound.
