Chinese Journal of Practical Surgery.2001;21(5):290-291.

Objective　In order to explore the prevalence of hypophosphatemia in postoperative patients of general surgery,as well as the time and dosage of phosphate replacement and its effects.Methods　To serum phosphate levels of 45 patients with phosphate replacement begun on the second postoperative day and 45 without replacement were monitored at the preoperative day,and the first,third,fifth and seventh postoperative day.Results　The incidence of hypophosphatemia was 91.1%(41/45) in cases without phosphate replacement.While it was 57.8%(26/45) in those with replacement.The serum phosphate concentrations in cases with phosphate replacement were higher than those without replacement on the third(P<0.001),fifth(P<0.05) and seventh(P<0.01) postoperative day.The Apache Ⅱ scores in cases with phosphate replacement decreased on the third postoperative days compared with those on the first day(P<0.001).Conclusion　The postoperative replacement of phosplates can avert the occurrence of hypophosphatemia and improve the Apache Ⅱ score.

Guoxiang DONG ; Xuan LI ; Jun ZHAO

Chinese Journal of Practical Surgery.2001;21(5):276-277.

Objective　This study was To investigate the incidence rate of Cockett syndrome and relationship between Cockett syndrome and varicose veins and deep venous incompetence of the left lower extremities.Methods　73 patients(100 legs) with varicose veins of the lower extremities were investigated by descending deep venography and iliography preoperatively.Results　There were 35(47.9%) cases with abnormalities of the left common iliac vein (ALCIV)in all the cases.There were 31 cases with this conditions in the patients with varicose veins of the left or both lower extremity.While in the patients with varicose veins of the only right lower extremity,there were only 4 cases with ALCIV.In contrast,there was a significant difference between groups(χ2=9.8641,P=0.0017).In the patients with ALCIV,14 cases with Ⅲ or Ⅳ grade of deep venous incomptence were found, and only 6 cases with deep venous incompetence in the patients without ALCIV.There was a significant difference(χ2=5.3688,P=0.0205).Conclusion　Cockett's syndrome frequently occurs in varicose veins of the left lower extremity.There is a relationship between them.Cockett's syndrome might be one of the causes for the deep venous incompetence of the left leg.

Clinical analysis of 531 cases of abdominal surgery with hypertension.

Jing WANG ; Yantao WU

Chinese Journal of Practical Surgery.2001;21(5):280-282.

Objective　To evaluate adbomen surgery in patients who are found to have poorly controlled or untreated hypertension before operation.Methods　From January 1997 to December 1998,the perioperative clinical data of 531 patients with hypertension and undergoing abdomen surgery in our hospital were retrospectively analyzed.Results　The incidences of perioperative hypertensive events were not significantly different,between controlled and uncontrolled patients with grade one and grade two (P>0.05).In grade three and systolic hypertension,certain perioperative complications in patients with poorly controlled hypertension were higher than in those with well-controlled hypertension(P<0.05).Conclusion　The patients with grade on e and grade two hypertension are not at increased operative risk.In Patients with grade three and systolic hypertension,perioperative complications are increased and elective surgery should be postponed until their blood pressure is brought under 180/110 mmHg over 1 to 2 weeks.

Chinese Journal of Practical Surgery.2001;21(4):228-229.

Objective To study how to reduce the incidence rate of skin flap necrosis after the eradicative resection of breast cancer. Methods 45 patients with breast cancer underwent eradicative operation with new methods to prevent the necrosis of skin flap,and they were studied and compared with 1210 cases treated by traditional ways. Results With the new methods adopted, the necrosis rate of skin flap following eradicative operation of breast cancer was reduced from 45%(original)to 2%(present).Statistic analysis showed that there was outstanding difference between them. Conclusion In the eradicative operation of breast cancer,the key to prevent the necrosis rate of skin flap is:prevention of subaxillary lymphatic fistula, two tubular drainage set individually in subcostalis and subaxillaris, appropriate force of chest bandaging, proper thickness of skin flap and perfect suture without tension.

Analysis of 67 cases with secondary carcinoma of the liver.

Yingbo WANG ; Zhongli XU

Chinese Journal of Practical Surgery.2001;21(4):222-224.

Objective The purpose of this study was to determine the indication,methods,safety and efficacy of hepatic resection for metastatic carcinoma of the liver. Methods Sixty-nine consecutive hepatic resections in 67 patients with secondary carcinoma of the liver were reviewed. Results One case died and operative mortality rate was 1.5 %.Median follow-up was 5 years, ranging from 1 to 7 years. The 1、3、5-year survival rates for all patients were 28.36%、 19.40% 、and 11.94% respectively. The survival rate of over 5-years in the hepatic resection for metastatic colorectal carcinoma was 21.43%. Conclusions Surgical resection of metastatic disease to liver is not only safe but also curative. We recommend that for any patient with metastatic carcinoma of the liver, an anatomic distribution of tumors to preserve hepatic function after resection and fitness to withstand the procedure should be considered for resection.

The resect margin of hepatectomy for primary hepatocellular carcinoma

Aijun YUAN ; Xingyao HUANG

Chinese Journal of Practical Surgery.2001;21(4):220-221.

Objective To understand the effect of the resect margin(RM)to hepatectomy for primary hepatocellularcarcinoma(PHC).Methods In 544 cases,72 cases were small PHC(≤3cm),473 cases were large PHC(＞3cm). Four groups were classified according to the distance of RM The 5-year recurrence rate and survival rate after hepatic resection in each group were analyzed. Results RM with residue cancer or cancer embolus had a high 5-year recurrencre rate and lower survival rate in both small and large PHC. Small PHC with RM≥1.0cm and large PHC with RM≥2.0cm had higher 5-year survival rate and lower recurrence rate. Conclusion We recommend RM≥1.0cm for smallPHC and RM≥2.0cm for large PHC.

Shi CHENG ; Zhiqiang ZHONG ; Ruotian WANG ; Yiezhi ZHAO ; Zhihong LI ; Ming JIANG ; Huisheng YUAN ; Dongbo FAN

Chinese Journal of Practical Surgery.2001;21(4):216-217.

Objective To improve the level of diagnosis and treatment of the sharp injury in the back. Methods 47 cases which were treated from Jan 1991 to May 2000 were reviewed. ResultsAmong 37 cases who underwent the exploration, 5 cases died. Among 10 cases who underwent conservative treatment, 2 cases died. ConclusionThe condition of sharp injury in the back is very complicated,it is easy to be misdiagnosed, the mortality is high. Saving should be equalled with the diagnosis and treatment. The application of wound exploration, abdominal puncture, ultrasound examination and X-ray checking is valuable to the diagnosis. The patients with operation indications should be operated at once,while the others should be observed for some time to prevent the delayed clinical manifestation.

Chinese Journal of Practical Surgery.2001;21(4):213-215.

Objectives To evaluate the effects of enteral nutrition(EN)and parenteral nutrition(PN)support in critically ill surgical patients. Methods 80 patients who could not eat were randomized into two groups:one group receivedEN,the other group received PN. The nutrition parameters including nitrogen balance, serum levels of albumin, prealbumin, transferrin and retinal-binding protein,immunity function parameters including immunoglobulin A, immunoglobulin G,immunoglobulin M,and natural kill cell activity, and patients'tolerability parameters including glutamic-oxalacetic transaminase, glutarmic-pyruvic transaminase, blood urea nitrogen and creatinine,and plasma glucose were compared. Results After 10 days'therapy,the two groups all turned from negative nitrogen balance to positive nitrogen balance. The nutrition parameters and immunity function parameters increased significantly in both groups and the latter in group EN increased more. For tolerability parameters, blood sugar in group PN increased obviously and no change in EN group. ConclusionsBoth EN and PN play a rde in nutrition support and elevation of immunity function. Patients tolerate well. EN has better effects on elevation of immunity function and patients tolerate better compared with PN.
