ABSTRACT
Objective To investigate the effect of carbon dioxide (CO2) pneumoperitoneum with different duration periods on renal function.Methods Eighty-nine patients undergoing laparoscopic operations from October 2009 to December 2011 were divided into 3 groups according to operative time.The patients whose operative time was less than 1 hour belonged to group T1,between 1 hour and 2 hours belonged to group T2,and more than 2 hours belonged to group T3.The levels of serum creatinine,urinary creatinine,urinary microalbumin were detected at preoperation as well as 10 minutes,1 hour,24 hours after operation.Results There was no significant difference regarding of the endogenous creatinine clearance rate(Ccr) postoperatively between group T1 and T2 (P ＞ 0.05).The Ccr levels at 10 minutes after operation in group T3 was significant lower than at preoperation(P ＜0.05),and increased gradually at 1 h and 24 h after operation.The ratio of urinary microalbumin to urinary creatinine (A/C) increased at post-operation compared with at pre-operation in all 3 groups (P ＜ 0.05),but there was no significant difference between the 3 groups after operation (P ＞ 0.05).The renal function post-operation of patients over 60 years old was as same as that of patients less 60 years old in group T1 (P ＞ 0.05).However,the Ccr level in patients over 60 years old at post-operation was lower than that of patients less 60 years old in group T2 and T3 (P ＜ 0.05).Conclusion Long CO2 pneumoperitoneum could lead to the acute and obvious injury on renal function,especially in the patients over 60 years old.Fortunately,the renal function recovered to be normal gradually in a short time.
ABSTRACT
Objective To identify the types of pulmonary complications after pancreaticoduodenectomy,and to discuss the prevention and management of these complications.Methods Clinical data of 165 cases of pancreaticoduodenectomy in our hospital were retrospectively analyzed.Pulmonary complications were identified,therapeutic effects were observed.Results The incidence rate of pulmonary complications was 19.4％ ( 32/165),case-fatality rate was 6.25％ (2/32),two patients died from pneumonia,respiratory failure and ARDS.Complications mainly included pneumonia 13.9％ (23/165),pleural effusion 4.2％ (7/165),atelectasis 3.6％ (6/165),pneumothorax 1.8％ ( 3/165 ),respiratory failure 2.4％ (4/165) and ARDS 1.2％ (2/165).Conclusion Pulmonary complications after pancreaticoduodenectomy are not rare,especially for pulmonary infection and most are hospital acquired pneumonia.To understand rules and particularity of respiratory physiopathological changes after pancreaticoduodenectomy is very important for patients to safely pass over the perioperative period.
ABSTRACT
Purpose:To investigate the pathogenesis,diagnos is and treatment of hashimoto's disease(HD) complicated with papillary thyroid c ancer (PTC ). Methods:Clinical data of 12 cases of HD complicated with PTC un dergoing surgery were analysed retrospectively and followed-up for one half to 8 years. Results:In this series papillary thyroid cancer occurred in 25 % (12/48) in patients with HD, but correct preoperative diagnosis was obtained i n 3 (25%) of 12 cases.All patients had thyroid nodules and received thyroidectom y,3 cases underwent functional cervical clearance of lymph nodes. All patients w ere followed up for 6 months to 8 years and there was no death , no recurrence and no metastasis. Conclusions:HD can develop into PTC .The clinical diagnosis of coexistence of HD and PTC is still difficult. The key to diagnosis and rational treatment includes detailed understanding its clinical features, routine examin ation of serum antibodies and ultrasonography, selected scintigraphic thyroid s can or FNAB and finally quick frozen pathologic section in operation. HD complic ated with PTC should be treated surgically.Intraoperative frozen section diagnos is should be performed routinely so that HD complicated with PTC can be diagnose d.The operation procedure should be individualized.All patients should be given small dosage of thyroxine.
