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.

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.

Objective To explore the surgical management in patients with Bismuth Ⅳ hilar cholangiocarcinoma.Methods Retrospective study was used to analyze the clinical data with operative and pathologic diagnosis of Bismuth Ⅳ hilar cholangiocarcinoma in the recent five years.Results Of the 22 patients,there were 13 males and 9 females,with M∶F=1.4∶1.In the group of non-liver transplantation(NLTX),5 cases(31.3%) underwent resection(radical resection in 2 cases;palliative resection in 3 cases),and 11 cases had nonresectional internal or external drainage.In the liver transplantation group(LTX),the resection rate was 100 %(6/6).Five LTX cases survived for 28,19,17,12 and 9 months respectively,and one died from chronic rejection in 11 months after operation.In the NLTX group,the 1-and 2-yr survival rate was 32.1 % and 0% respectively.The 1-and 2-yr survival rate of LTX was 80.0 %(4/5)and 50.0 %(1/2)respectively.There was significant difference between the two groups in average survival rate(P=0.041).Conclusions Aggressive surgical treatment should be adopted for Bismuth Ⅳ hilar cholangiocarcinoma,and radical resection is crucial to enhance survival rate.LTX is a good choice for the patients with unresectable Bismuth Ⅳ hilar cholangiocarcinoma and the prognosis is satisfactory.

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.

Objective To explore the prevention and treatment of early pulmonary infection after liver(transplant).Methods A retrospective analysis was carried out on the clinical data of 34 cases suffered from post-transplant pulmonary infection among 62 cases of liver transplant.Results Among the 34 cases,27 cases recovered and 7 cases died.The sputum of 27 cases was cultured positive for bacteria and fungus(including) Gram-negative bacteria(51.9%),Gram-positive bacteria(29.6%) and fungus(18.5%),cytomegalovirus 1 case,EB virus in 1 case,and pathogens unknown in 5 cases.Conclusions (Gram-negative) bacteria are the main pathogens of pulmonary infection after liver transplant.The critical stage of pulmonary infection is the first week after operation.The perioperative management of respiratory tract and rational use of antibiotics are important for prevention and treatment of post-transplant pulmonary infection.

Objective:To explore the practical value of general anesthesia with non-intubated spontaneous breathing in uniportal thoracoscopic surgery in elderly patients.Methods:Clinical data of 86 elderly patients undergone uniportal thoracoscopy surgery during hospitalization at our hospital between March 2020 and December 2021 were retrospectively reviewed and analyzed.Based on the anesthesia intubation method, they were divided into a non-intubated spontaneous breathing video-assisted thoracic surgery group(NI-VATS group)and a one-lung ventilation video-assisted thoracic surgery group(OLV-VATS group), with 43 cases in each group.Data were compared on the inflammatory indexes, preparation time for anesthesia, time to awakening after anesthesia, intraoperative lung collapse score, mediastinal flutter score, time to postoperative feeding, digestive tract complications, sore throat, postoperative pulmonary atelectasis, and hospitalization time.Results:Compared with the OLV-VATS group, the NI-VATS group had a shorter anesthesia preparation time [(19.8±2.6)min vs.(32.3±4.5)min, t=-15.77, P<0.001]and a shorter time to awakening [(6.8±2.1)min vs.(11.9±2.9)min, t=-9.485, P<0.001], slightly poorer operating field during surgery, an unfavorable lung collapse score [(2.5±0.7) vs.(1.8±0.7) t=4.704, P<0.001], worse mediastinal flutter [(2.1±0.6) vs.(1.3±0.5), t=6.514, P<0.001]. Lower procalcitonin(PCT)[(0.189±0.130)μg/L vs.(0.264±0.123)μg/L, t=-2.744, P=0.007), a shorter time to postoperative feeding [(3.4±1.0)h vs.(5.5±1.0)h, t=-9.55, P<0.001], and lower rates of digestive tract reactions(4.7% vs.20.9%, χ2=5.108, P=0.024)and throat pain(4.7% vs.23.3%, χ2=6.198, P=0.013), and a shorter length of hospital stay [(3.8±0.3)d vs.(4.9±0.8)d, t=-7.266, P<0.001]. Conclusions:For the elderly patients undergoing uniportal thoracoscopic surgery, non-intubated spontaneous breathing may somewhat obstruct the operating field, but it can shorten the time of anesthesia and the time to awakening, does not increase complications from anesthesia and surgery, favors rapid postoperative recovery for patients and therefore should be promoted.

Objective To investigate the surgical methods and clinical effect of repairing the thumb tip defects in infants by applying the reversed first dorsal metacarpal radial artery island flaps along with anatomosing of nerves and veins.Methods Twenty-one cases with soft tissue defects of thumb tips caused by trauma were admitted from August,2015 to August,2017.The first dorsal metacarpal radial island artery flaps were transplanted reversely to repair the defects along with the anatomosis of nerves and veins.Among all the cases,the range of defect area was 2.0 cm×1.8 cm-3.0 cm×2.5 cm.The area range of the flap harvested during the surgery was 2.2 cm×2.0 cm-3.2 cm×2.7 cm.The regular post-operative followed-up was performed.Results All flaps survival after the surgeries,and the wounds were I-staged healing.All cases were followed-up by 3-18 months,and the average time was 7 months.The appearance and quality of the flaps were good.The range of motion of the metacarpophalangeal joints and interphalangeal joints was normal.According to the Upper Extremity Functional Evaluation Tentative Criteria set up by Hand Surgery Branch of Chinese Medical Association,14 cases were excellent,5 case was good,and 2 cases were fair.Conclusion The surgery of using the first dorsal metacarpal radial reversed island artery flap to repair the defect of thumb tip in infant,along with the anatomosis of nerve and vein,is a good method in repairing the defects due to its ease of operation,achievement of plump of finger tip and good recovery of appearance and sensation after the surgery.
