Objective To investigate the diagnosis and treatment of injury in choledocho-pancreatico-duodenal junction. Methods The clinical data of 6 patients with injury in choledocho-pancreatico-duodenal junction who had been admitted to Beijing Hospital from January 2000 to January 2008 were retrospectively analyzed. Results Of the 6 patients, 4 were diagnosed according to the intraoperative findings, cholangiography and fiber cholangioscopy. The 4 patients were cured after suture of the perforation in the choledocho-pancreatico-duodenal junction, T-tube drainage and abdominal drainage. Two patients developed severe abdominal and retroperitoneal infection and other complications after operation, and were diagnosed by cholangiography and fiber cholangioscopy. Of the 2 patients, 1 was cured and 1 died after multiple drainage procedures and debridement. Conclusions Diagnosis and treatment in the early stage are crucial for the curative purpose. Cholangingraphy and fiber cholangioscopy are effective in the diagnosis of injury in choledocho-pancreatico-duodenal junction. The suture of the perforation in the choledocho-pancreatico-duodenal junction, T-tube drainage and abdominal drainage should be chosen for patients who are diagnosed during primary operation. For patients with abdominal and retroperitoneal abscess and cellulitis, drainage and debridement should be performed, and biliopancreatic diversion and duodenal diverticularizatian are applied to patients when necessary.

Objective To investigate the relationship of the nutritional status with liver function and clinical outcomes of liver cancer patients treated with surgery.Methods Altogether 112 hospitalized patients undergoing surgical treatments for liver cancer were enrolled from October 2011 to October 2013.Their general clinical data were collected,including creatinine-height index (CHI),arm circumference,grip strenghth,albumin,prealbumin,and transferrin.The nutritional status was assessed using Patient-Generated Subjective Global Assessment (PG-SGA).The liver function was assessed with Child-Pugh classification.Postoperative infectious complications and the hospital stays were recorded to assess the clinical outcomes.The correlation between nutritional status and liver function,and that between nutritional status and clinical outcomes were analyzed.Results Among the 112 patients,70 (62.5％) were in normal nutritional status,34 (30.4％) were with moderate malnutrition,and 8 (7.1％) were with severe malnutrition according to PG-SGA scores.PG-SGA assessment showed strong consistence with CHI nutritional assessment (κ =0.760,P =0.000),and moderate consistence with arm circumference assessment (κ =0.564,P =0.000),and grip strength assessment (κ =0.523,P =0.000).The live function classified by Child-Pugh was found highly correlated with PG-SGA assessment (rs =0.829,P =0.000).Postoperative infectious complications and hospital stays were both positively correlated with PG-SGA assessment (r =0.349,P =0.000 ; r =0.624,P =0.000).Conclusions PD-SGA combining with CHI can be used for the nutritional status assessment of liver cancer patients undergoing surgical treatments.The nutritional status of the patients has positive correlation with live function,infectious complications,and postoperative hospital stays.

Objective To investigate the changes of electrolyte metabolism in patients undergoing moderate elective abdominal operation,and explore its relationship with postoperative complications.Methods The clinical data of 1117 inpatients (age ≥ 18 years) who had undergone moderate elective abdominal operation in the Department of General Surgery of Beijing Hospital from January 1,2011 to December 31,2011 were retrospectively analyzed.They received postoperative fasting for ≥ 3 days,and the preoperative liver function and renal function were normal.The perioperative electrolyte changes and clinical outcomes were recorded.For patients with normal preoperative electrolytes but abnormal postoperative electrolytes,its potential correlations with the postoperative infections and total complications were analyzed.Results The rates of abnormal postoperative electrolytes were as follows:potassium,24.1％ ; sodium,6.4％ ; chloride,27.6％ ; calcium,61.7％ ; magnesium,16.3％ ; and phosphorus,71％.The vast majority of ion levels were below the normal levels.The total complication rate was 19.7％ and the postoperative infection rate was 17.19％.Univariate logistic regression analysis showed that the postoperative total and infective complications were significantly associated with the increased (P =0.007) or decreased (P =0.007) serum potassium,the decreased serum sodium (P =0.016),the decreased serum phosphorus (P =0.004),and the decreased magnesium (P =0.049).Conclusions Electrolyte decrease is common after moderate elective abdominal operations.There is a certain correlation between postoperative electrolyte decrease and postoperative complications.Therefore,attention should be paid to maintain electrolyte balance during the perioperative period.
