Objective To evaluate the perioperative safety of laparoscopic cholecystectomy(LC) in patients with gallstones complicated with end-stage renal disease(ESRD). Methods Clinical data of 41 patients with gallstones accompanying ESRD treated with LC(ESRD Group) between May 1994 and May 2005 were analyzed retrospectively.Another 200 patients without ESRD(non-ESRD Group) receiving LC during the same period were randomly selected for comparison.Results The patients in the ESRD Group were older than those in the non-ESRD Group(49.8?11.9 years vs 44.2?12.3 years;t=2.655,P=0.008).There were significant differences between the ESRD Group and the non-ESRD Group in hemoglobin levels(76.3?11.7 g/L vs 120.1?8.4(g/L)) and platelet count [(141?36)?10~9/L vs(183?51)?10~9/L)] (t=22.905 and 6.226;P

Objective To sum up clinical experience on subfascial endoscopic perforator surgery (SEPS) for the treatment of severe chronic venous insufficiency (CVI) of the lower extremities. Methods Fifty-one patients (64 limbs) with severe CVI received SEPS from Nov. 1999 to Aug.2002. CEAP classification, scoring of venous dysfunction (SVD), Color Doppler, Color Doppler velocity profile (CDVP), venography and air plethysmography (APG) were applied to assess the status of the affected limbs before and after operation. Results The postoperative follow-up was made from 3 to 35 months with the follow-up rate of 90.6% (58/64 limbs). No limbs suffered from recurrent superficial varicose. Venous ulcer was healed in 40 limbs (97.6%) and the ulcer ameliorated significantly in one limb. Ulcer healing time ranged from 9 to 91 days with the average time of (32?5) days. The average SVD was (13.9?1.7) preoperatively , while (6.4?0.8)postoperatively ( P

0.05). Conclusions LS,whereas of less traumatic and low morbidity, results in comparable effects as OS for the treatment of ITP.

OBJECTIVE To understand and use reasonably the strategy of prevention and management of overwhelming postsplenectomy infection(OPSI). METHODS According to intervention to patients with postsplenectomy by means of education,vaccination,antibotic prophylaxis after April 1998,clinical and follow-up data were reviewed and analyzed from 337 cases patients with traumatic splenectomy from Jan 1992 to Jan 2004,and correlative factors of four OPSI cases were further analyzed. RESULTS Incidence of OPSI descended obviously after intervention(P

OBJECTIVETo evaluate the result of laparoscopic colorectomy in treatment of colorectal cancer.
METHODSLaparoscopic colorectal surgery was performed in 78 patients with colorectal cancer. Operative procedures, complications and postoperative recovery were studied.
RESULTNone of the 78 patients died of laparoscopic colorectal surgery or complications. Eleven patients died from tumor metastasis and 2 from other causes. Twenty-one, 17, 8 patients for 1, 3, 5 years survived respectively. In nine patients who had received operation less than 1 year, no tumor recurrence or metastasis was found except in 1 patient 11 months after operation.
CONCLUSIONLaparoscopic colorectal cancer resection is essential to colectomy for colon and rectum cancer when indicated.

Aortic dissection, especially Stanford type A aortic dissection, is an acutely progressive and highly fatal cardiovascular disease.Early prevention and timely treatment can greatly reduce mortality and reduce the burden on families and society.However, due to the etiological mechanism is still unclear, the clinical treatment is still mainly surgery, and the early prevention and drug application are very limited.And some recent studies have found that ferroptosis may play an important role in the occurrence and development of aortic dissection, revealing the relationship between them may provide ideas for the prevention, treatment and scientific research of the disease.
