Intrathoracic manifestations of cervical anastomotic leaks after transhiatal and transthoracic oesophagectomy

Background: A possible advantage of cervical oesophagogastrostomy over intrathoracic anastomosis after oesophagectomy is the presumed mild clinical course of cervical anastomotic leakage. The incidence and consequences of intrathoracic manifestations after cervical anastomotic leakage remain unclear, and were investigated in this study. Methods: Consecutive patients undergoing potentially curative transhiatal oesophagectomy (THO) or transthoracic oesophagectomy (TTO) with cervical oesophagogastrostomy between 1993 and 2007 were included. Intrathoracic manifestations after cervical anastomotic leakage were compared following THO and TTO. Multivariable logistic regression analysis was used to identify potential risk factors for intrathoracic manifestations. Results: Seventy-nine (15.8 per cent) of 501 patients developed anastomotic leakage after THO compared with 50 (15.3 per cent) of 327 after TTO (P = 0.853). Intrathoracic manifestations developed in 21 (27 per cent) and 22 (44 per cent) patients respectively (P = 0.041). A transthoracic approach was the only independent predictor of the development of intrathoracic manifestations in patients with cervical leakage (odds ratio 2.60; P = 0.022). Total hospital stay (P < 0.001), intensive care unit stay (P < 0.001) and in-hospital mortality (P = 0.035) were greater in patients with intrathoracic manifestations than in those without. Conclusion: Intrathoracic manifestations of cervical anastomotic leakage are associated with a prolonged hospital stay, carry a higher mortality and occur more frequently after TTO than THO

Pylorus-preserving pancreatoduodenectomy: Influence of a Billroth I versus a Billroth II type of reconstruction on gastric emptying

Background/Aim: Delayed gastric emptying (DGE) is a frequent problem after pylorus-preserving pancreatoduodenectomy. Important risk factors are the presence of intra-abdominal complications. Searching for other causes, this study evaluates the influence of the type of reconstruction after a pancreatoduodenectomy (Billroth I vs. Billroth II; B I vs. B II on DGE. Methods: A retrospective study was performed evaluating consecutive patients from two surgical institutes. 174 patients were included (B II type of reconstruction n=123, period 1992-1996; B I type of reconstruction n=51, period 1988-1998). DGE was defined by gastric stasis requiring nasogastric intubation for 10 days or more or the inability to tolerate a regular diet on or before the 14th postoperative day. Results: After a B I type of reconstruction, there was significantly longer nasogastric intubation period as compared with a B II type of reconstruction (B I median 13 days, range 4-47, B II median 6 days, range 1-40;

Risk Factors for Development of Benign Cervical Strictures After Esophagectomy

Objective: To identify independent risk factors for development of benign cervical anastomotic strictures in general and specifically for refractory strictures after esophagectomy in a large series of patients. Summary Background Data: Benign strictures develop frequently when a cervical anastomosis is performed after esophagectomy, causing burdensome symptoms and poor quality of life. Methods: From 1996 to 2006, all patients in the Academic Medical Center prospective database undergoing esophagectomy with a cervical anastomosis were included. Stricture was defined as dysphagia requiring endoscopic dilation of the anastomosis. Prediction of stricture was assessed using uni- and multivariate logistic regression analysis. Evaluation of risk factors was also performed for refractory strictures (>2 times the median number of dilations in all patients with stricture) in a similar fashion. Results: A total of 607 patients underwent potentially curative esophagectomy, with an in-hospital mortality of 2.5%. During follow-up, 253 (41.7%) patients developed a stricture after a median time of 74 days, requiring a median number of 5 dilations. Cardiovascular disease (P = 0.002), gastric tube compared with colonic interposition (P = 0.03), and anastomotic leakage (P = 0.002) were predictive for development of stricture in multivariate analysis. Development of stricture within 90 days after surgery (P = 0.001), chemoradiotherapy (P = 0.02), and anastomotic leakage (P = 0.03) were independent predictors for refractory strictures requiring over 10 dilations. Conclusions: The benign cervical stricture rate after esophagectomy was relatively high. Cardiovascular disease, gastric tube compared with colonic interposition and postoperative anastomotic leakage were independent predictors for development of benign anastomotic stricture. Anastomotic leakage, chemoradiotherapy and early development of stricture were independently associated with the development of refractory strictures, requiring a higher number of dilations. Prevention of anastomotic stricture formation should be focused on prevention of anastomotic leakage
