ObjectiveTo explore the feasibility and characteristics of three-port laparoscopic cholecystectomy (LC) in the treatment of cholecystitis with gallbladder calculi incarceration. MethodsThe clinical data of 160 patients with gallbladder calculi incarceration treated by three-port LC between July 2010 and December 2014 were analyzed retrospectively. Among the patients, there were 104 cases of calculi incarcerated in the gallbladder neck area, 20 cases in the cystic gall duct, and 36 cases in the gallbladder ampullar region. Elective operations were carried out for 120 patients and 40 underwent emergency operation. ResultsThree-port LC was successfully completed in 154 patients (96.25%), and the other 6 patients were converted to open surgery among whom 2 underwent elective operation (1.67%) and 4 underwent emergency operation (10.00%). Two converted patients in the elective operation group had Mirizzi syndrome and gallbladder carcinoma respectively; all the 4 converted patients in the emergency operation group had a disease course of about one week with compacted triangle structure and gallbladder edema thickening of 1.0 cm, causing difficult separation under laparoscope. Seventy patients had varying degrees of enlargement and edema of gallbladder, 60 had varying degrees of gallbladder atrophy, and 30 had almost normal gallbladder. There were 80 cases of dark green thick bile, 10 of purulent bile, 40 of white bile, and 30 of empty gallbladder and no bile. No complications were found during the follow-up of 6 to 36 months, except that one patient was found to have secondary common bile duct stones three months after discharge, and the patient was cured by endoscopic retrograde cholangiopancreatography. Conclusions Elective or emergency three-port LC is safe and feasible for gallbladder calculi incarceration as long as the operator had skilled technique and made the right decision on opportunity of conversion.
ObjectiveTo investigate the clinical efficacy and safety of lithotripsy under flexible ureteroscope using 200 μm holmium laser for medullary sponge kidney stones. MethodsWe identified and retrospectively reviewed 10 patients who underwent flexible ureteroscopic lithotripsy for medullary sponge kidney calculi between January 2013 and July 2014. The remission of clinical symptoms and incidence of perioperative complications were observed. ResultsThe staged surgery was performed on 10 bilateral cases with one session for each kidney. The operative time of our cohort was 130-180 minutes. The postoperative average hemoglobin was not significantly reduced (110.6 g/L) as compared with preoperative average hemoglobin (116.8 g/L) (P>0.05). Two patients had fever after operation and temperatures became normal by anti-infection. The renal function and plain film of kidney-ureter-bladokr (KUB) and CT scan were rechecked for all cases on three months after operation. The kidney function in 3 cases of chronic renal failure was ameliorated to varying degrees. The postoperative average of serum creatinine (196.2 μmol/L) was reduced as compared with the preoperative average serum creatinine (385.7 μmol/L) (P<0.05). Six patients reported spontaneous discharge of residuary stones during three months after surgery. KUB and CT scan proved significant reduction of the loads of stones for all cases after operation. ConclusionFlexible ureteroscope with 200 μm holmium laser lithotripsy is a safe and effective treatment for medullary sponge kidney stones based on its effect on amelioration of symptom and renal function.
ObjectiveTo investigate the necessity of indwelling ureteral stent before flexible ureteroscopic lithotripsy in the treatment of upper urinary tract calculi. MethodsEighty-five patients with upper urinary tract calculi treated between June 2013 and December 2014 were divided into two groups:group A (without indwelling stent, n=42) and group B (with indwelling stent, n=43).Incidence of stent-related urinary tract symptoms, operation time, one-time success rate of placement for ureteral access sheath, and stone clearance rate were compared between the two groups. ResultsThe operation time and stone clearance rate had no statistically significant differences between the two groups (P > 0.05).The incidence of stent-related urinary tract symptoms and one-time success rate of placement for ureteral access sheath in group B were significantly better than those in group A (P < 0.05). ConclusionFor one-phase operation success, we suggest that indwelling ureteral stent is necessary before flexible ureteroscopyic lithotripsy for treating upper urinary tract calculi.
ObjectiveTo explore the value liver resection combined with intraoperative radiofrequency ablation during the same period in the treatment of multiple liver cancer. MethodsWe retrospectively analyzed the clinical data of 33 patients with multiple liver cancer treated between January 2005 and April 2013. All the patients were treated by liver resection combined with intraoperative radiofrequency ablation in the same period. There were 91 tumor foci in 33 patients, among which 39 tumor foci were surgically removed, and 52 tumor foci were radiofrequency ablated. Ultrasonography and enhanced CT/MRI were performed for the patients 1 year, 2 years and 3 years after surgery. ResultsNo bleeding or death occurred during the operation. It was observed that the transient liver function was damaged after surgery, but it quickly returned to A level after treatment. All the patients had no perioperative death or other serious complications. Tumor recurrence rate was 16.1% in the first year, 48.4% in the second year and 93.5% in the third year after surgery. ConclusionLiver resection combined with intraoperative radiofrequency ablation for multiple liver cancer in the same period is feasible and safe, without increasing the average length of hospital stay, operative mortality rate and postoperative tumor recurrence rate.
ObjectiveTo evaluate the safety and efficacy of flexible ureteroscopic lithotripsy for renal stones of longer than 2 cm in diameter. MethodsFrom August 2012 to July 2014, 15 selected patients with renal calculi of longer than 2 cm in diameter underwent flexible ureteroscopic lithotripsy with holmium laser by the same surgeon. Preoperative indwelling ureteral stent was performed for 1-2 weeks, and super smooth guidewire was inserted after checking and dilation of the ureter was performed with F8.0/9.8 rigid ureterosope. Flexible ureteroscope sheath was inserted through guidewire. Ureterosope was followed by flexible ureteroscope sheath. Larger stone fragments were removed by basket. ResultsThe success rate of ureteroscopic insertion was 100% and no severe intraoperative complications occurred. The operation time ranged from 50 to 125 minutes averaging 75. No ureteral perforations or pyonephrosis or acute renal insufficiency occurred. Four patients had high fever after operation and improved after positive anti-infection treatment. After 2 days, the stone-free rate was 73.3% (11/15) by reviewing KUB. The follow-up of 4 weeks showed the stone-free rate was 86.7% (13/15). One case of stone fragments retained in the middle and lower ureter and the fragments were taken out by ureteroscopic lithotripsy. The other case of renal residual calculi was operated by flexible ureteroscope holmium laser lithotripsy in two stage. ConclusionFlexible ureteroscopic lithotripsy is a favorable option for patients with renal stones of longer than 2 cm in diameter, especially for recurrent renal calculi.
