ABSTRACT
Objective To investigate the efficacy of gastric bypass surgery for the treatment of nonobese type 2 diabetes mellitus. Methods From November 2008 to August 2009, 40 patients with gastric diseases and nonobese type 2 diabetes mellitus were admitted to the Changhai Hospital, and their clinical data were prospectively studied. All patients were randomly divided into 4 groups; 10 patients received Billroth I distal gastrectomy +gastroduodenal anastomosis (BⅠ group) , 10 received proximal gastrectomy + remanant gastric esophageal anastomosis ( PG group), 10 received total gastrectomy + esophagoduodenal Y-anastomosis ( RY group) and 10received subtotal gastrectomy Billroth Ⅱ gastro-jejunostomy (BⅡ group). The length of hospital stay, pre- and postoperative body mass indexes (BMIs) , waist circumferences, levels of fasting blood glucose (FBG) , glycated hemoglobin ( GHbA1) , fasting serum insulin (FSI) and fasting C-peptide (FCP) of patients in the 4 groups were compared. All data were analyzed using analysis of variance, LSD-t test, paired t test or chi-square test. Results The clinical effects of the 4 different operative procedures on the gastric diseases were similar. The levels of FBG were (8.0 ±2.9)mmol/L before operation and (5.9 ±0.7)mmol/L after operation in the RY group, with a significant difference (t = 2. 342, P < 0. 05). The preoperative level of GHbA1 in the RY group was 7.7% ± 1.1%, which was significantly higher than 6. 9% ± 0. 6% at 2 months after the operation and 6. 1 % ± 0. 4% at 6 months after the operation (t = 4. 920, 3.012, P < 0.05). The preoperative level of FCP in the RY group was (1.30 ±0.54) μg/L, which was significantly lower than (1.95 ± 0.86) μg/L at 2 months after the operation and (2.18 ± 0.63)μg/L at 6 months after the operation (t =6. 063, 4. 651, P < 0.05). The levels of FSI in the RY group at postoperative month 1, 2 and 6 were (18 ±5) , (19 ±3) , (21 ±3) mU/L, which were significantly higher than the level of FSI [(11 ±4) mU/L]before operation (t =3. 158, 4. 502, 7. 517, P <0. 05). Preoperative levels of FBG, GHbA1, FSI and FCP in the B Ⅱ group were (8. 3 ± 1. 3) mmol/L, 7. 7% ±0. 9% , (13±4)mU/L and (1.34±0.48) μg/L, which were ignificantly different from (6.7 ± 1.2)mmol/L, 6.8%± 0.8%, (18±4)mU/L and ( 1.68 ±0.46) μg/L at postoperative month 1, (6.4 ± 1.3)mmol/L, 6.3% ±0.6% ,(18±4)mU/L and (1. 96 ± 0. 67) μg/L at postoperative month 2, and (5. 6 ±0. 7) mmol/L, 6.0%±0.3%, (19 ± 4) mU/L and (2.27 ± 0. 59) |μg/L at postoperative month 6 (t = 2. 468, 2. 598, 6. 028; 3. 055, 4. 586,4.572; 3.618, 5.860, 8.577; 2.300, 3.511, 3.943, P<0.05). The levels of FBG,GHbA1 and FCP in the 4 groups at 2 months after surgery were significantly different from those at 6 months after surgery (F = 4. 699,14. 378; 7.411, 29. 192; 3. 335, 9. 334, P < 0.05). The levels of FSI in the 4 groups at different time points were significantly different (F =2. 896, 7. 012, 11. 998, P < 0.05). Conclusion The efficacy of gastric bypass surgery for the treatment of nonobese type 2 diabetes mellitus is satisfactory.
ABSTRACT
Objective To study the feasibility and safety of laparoscopically assisted hepatectomy without choledochotomy and T-tube drainage for the treatment of hepatolithiasis.Methods The study included 11 patients with hepatolithiasis in the left intrahepatic duct.Of the 11 patients,8 patients were complicated with choledocholith and 5 patients with cholecystolithiasis.After laparoscopically assisted left hepatectomy,extrahepatic bile duct stone removal and right hepatic duct exploration were carried out under video-assisted choledochoscopy through the left hepatic duct,without choledochotomy and T-tube drainage.Results The operation was successfully accomplished in all the 11 patients.Liver procedures included laparoscopically assisted left lateral lobectomy in 5 patients and left hemihepatectomy in 6 patients.The mean operation time was 128 min(range,110~150 min),and the mean blood loss was 95 ml(range,50~150 ml).No serious postoperative complications occurred.The mean postoperative hospital stay was 7 d(range,5~10 d).The 11 patients were followed for a mean of 7.6 months(range,2~16 months).The curative effects were classified as excellent in 10 patients and good in 1.No residual or recurrent stones were noted.Conclusions Laparoscopically asisted hepatectomy without T-tube drainage for the treatment of hepatolithiasis is feasible and safe for selected patients.This procedure offers advantages of simplicity of performance,short operation time,and fewer complications,being a worthwhile minimally invasive alternative.
ABSTRACT
Objective To study the feasibility and safety of hand-assisted laparoscopic hepatectomy combined with splenectomy. Methods Hand-assisted laparoscopic hepatectomy combined with splenectomy was performed in 3 patients. A midline epigastric or right subcostal incision was made for hand-assisted port. The attachments of the spleen were dissected with a harmonic scalpel and the pedicle of the spleen was severed with the Endo-GIA. The transection of the liver was conducted using the harmonic scalpel dissection and nonabsorbable polymer clipping. The cut surface of the liver was closed by interrupted sutures. Results The operation was successfully completed in all the 3 patients. The surgical time was 130 min, 115 min, and 145 min, and the blood loss was 350 ml, 50 ml, and 150 ml, respectively. No serious postoperative complications occurred. The postoperative hospital stay was 9, 7, and 11 days, respectively. Follow-up observations for 6, 23, and 5 months showed no recurrence. Conclusions Hand-assisted laparoscopic hepatectomy combined with splenectomy is feasible and safe in selected patients .
ABSTRACT
Objective To study the feasibility and invasiveness of hand-assisted laparoscopic hepatectomy(HALH) for liver cancer.Methods Forty patients undergoing hepatectomy for liver cancer were randomly divided into HALH group and open hepatectomy(OH) group.Data of patients of two groups,Which included operating time,intraoperative blood loss,length of incision,postoperative flatus time,hospital stay,complications and C-reactive protein(CRP) were compared.Results The mean intraoperative blood loss,length of incision,postoperative flatus time,hospital stay and CRP in HALH group were significantly less than that in OH group;but there was no significant difference in operating time,or complication and recurrence rate.Conclusions HALH for liver cancer is less traumatic,and achieves faster patient recovery.It is feasible and safe in selected patients.
ABSTRACT
Objective To study the feasibility and safety of hand-assisted laparoscopic modified Sugiura procedure for portal hypertension. Methods Ten patients with cirrhotic portal hypertension and splenomegaly underwent hand-assisted laparoscopic modified Sugiura procedure. Results The operation was successful in all 10 patients. Mean surgical time was 189.5 minutes, Mean blood loss was 141 ml. There was no mortality nor serious postoperative complications. The mean postoperative hospital stay was 10. 5 days. Conclusions Hand-assisted laparoscopic modified Sugiura procedure is feasible and safe. It helps to reduce operative difficulty and control intraoperative bleeding for patients with portal hypertension.
ABSTRACT
Many studies, both retrospective and prospective, have shown that there is a circadian variation in acute cardiovascular events with a peak during the morning and a trough during the night since the mid 1980s. In addition to the morning peak, a secondary less prominent peak has been observed in the late afternoon in many studies. This circadian variation may well be at least partly linked to the known physiological circadian rhythms. Because the duration of the therapeutic effect of many drugs taken at the conventional time will have reached subtherapeutic levels at the time of waking and commencing activity the following morning, timing of medication is discussed to improve the protection of the patients with cardiovascular disease in the morning waking hours.
