title: 'Cross-section gastroenterostomy' in patients with irresectable periampullary carcinoma.
abstract: BACKGROUND
  The most frequent complication following gastroenterostomy (GE) for gastric outlet obstruction is delayed gastric emptying (DGE), which occurs in roughly 20% of patients. There is evidence that DGE may be linked to the longitudinal incision of the jejunum and that a transverse incision (cross-section GE) may decrease the incidence of DGE following GE.
  
  
  METHODS
  In contrast to the orthodox GE, the jejunum is severed transversely up to a margin of 1.5 cm at the mesenteric border and the anastomosis is created with a single running suture. A Braun anastomosis is added 20-30 cm distally to the GE. Patients were followed prospectively with special regard to the occurrence of DGE.
  
  
  RESULTS
  Between 1 August 1994 and 1 August 1998, 25 patients underwent cross-section GE, mostly because of an irresectable periampullary carcinoma. Eight patients exhibited clinical signs of gastric outlet obstruction preoperatively, while in 17 the GE was performed on a prophylactic basis. A biliary bypass was added in 15 patients. There was no disruption of the GE, but one patient died in hospital (4%). The nasogastric tube was withdrawn on the first postoperative day (range 0-6 days), a liquid diet was started on the fifth day (range 2-7 days) and a full regular diet was tolerated at a median of 9 days (6-14 days).The incidence of DGE was 4%: only the single patient who died fulfilled the formal criteria for DGE.
  
  
  CONCLUSIONS
  In contrast to orthodox GE, DGE seems to be of minor clinical importance following cross-section GE. As the technique is easy to perform, is free of specific complications and leads to a low incidence of DGE, it should be considered as an alternative to conventional GE.
