ObjectiveTo investigate and compare the advantages and disadvantages of laparoscopic cholecystolithotomy and laparoscopic cholecystectomy for patients with gallbladder stone. MethodsThe eligible patients with gallbladder stones hospitalized in our department between January 2007 and December 2011 were included, and all of them received either laparoscopic cholecystolithotomy (observation group) or laparoscopic cholecystectomy (control group) minimally-invasive surgery. The operation time, bleeding volume, enterokinesia recovery time, hospital stay, post-operative complication and follow-up results were compared between the two groups. ResultsA total of 148 patients were included, with 68 patients in the observation group and 80 patients in the control group. In this cohort, the success rate of surgery for the observation group and the control group was 100.0% (68/68) and 98.8% (79/80), respectively; and the success rate of complete stone removal was 100% for both two groups. B-ultrasound examination after 2 weeks of treatment showed that gallbladder wall was normal and gallbladder contraction rate was more than 30% for all patients with laparoscopic cholecystolithotomy. The operation time was (49.6±5.2) minutes for the observation group and (50.5±6.2) minutes for the control group, and bleeding volume was (9.5±1.4) mL for the observation group and (50.2±8.1) mL for the control group; the difference in bleeding volume was significant between the two groups (P<0.05). The difference in enterokinesia recovery time[(33.9±2.2) and (34.4±2.6) minutes] or hospital stay[(3.4±1.0) and (3.6±1.2) days] between the observation group and the control group was not significant (both P >0.05). The post-operative complications of bleeding, bile leakage and wound infection were not observed in both two groups, and all patients were followed up for 6 to 12 months with no stone recurrence; and only 2.7% of patients (1/37) had stone recurrence after 3-year follow-up. ConclusionBoth laparoscopic cholecystolithotomy and laparoscopic cholecystectomy procedures are safe and efficient. However, laparoscopic cholecystolithotomy not only reserves gallbladder but also has superiority of less bleeding volume.
ObjectiveTo evaluate the advantages and disadvantages of parasternal minimally incision surgery over median sternotomy to treat atrial septal defect (ASD) patients. MethodsWe retrospectively analyzed the clinical data of 55 ASD patients received ASD closure under cardiopulmonary bypass (CPB) in Department of Cardiovascular Surgery, West China Hospital from November 2010 through March 2014. There were 16 males and 39 females with an average age of 25.8 (range, 9-56 years). All the patients were divided into two groups depending on different surgical approach:a median sternotomy group (a MS group, 15 patients)and a parasternal minimally incision group (a PMI group, 40 patients). There was no statistical difference in age, gender, weight, cardiac function classification (NYHA), and atrial septal defect diameter between the two groups (P>0.05). We analyzed the clinical data of the patients and followed up for 6 months. ResultsAfter operation, no death occurred in the two groups. One patient in the MS group prolonged hospitalization due to poor postoperative heart function. One patient in the PMI group prolonged hospitalization because of pulmonary infection. Patients in the PMI group had longer operation time (P=0.007) and cardiopulmonary bypass (CPB) time (P < 0.001), higher cost in hospital (P=0.040), less intraoperative blood loss, less postoperative drainage volume on the first day (both P < 0.001). There was no statistical difference in aortic clamp time (P=0.500) mean hospital stay (P=0.290) after operation between the two groups. To eliminate the interference of the learning curve, there was no statistical difference in operation time (P=0.275) and hospitalization cost (P=0.188) between the two groups. While there was a statistical difference in CPB time between the two groups (P=0.007). There was no remnant shunts or wound complications in the two groups at the end of following up for 6 months. More patients in the PMI group could engage in non-strenuous activities with a statistical difference (P < 0.001). ConclusionParasternal minimally incision in the treatment of atrial septal defect is safe, effective, minimally invasive, with easy operation and shorter learning curve. It can be used as an important part of minimally invasive treatment procedure of congenital heart disease.
Objective To investigate the early effectiveness of transiliac-transsacral screws internal fixation assisted by augmented reality navigation system HoloSight (hereinafter referred to as “computer navigation system”) in the treatment of posterior pelvic ring injuries. MethodsA retrospective analysis was made in the 41 patients with posterior pelvic ring injuries who had been treated surgically with transiliac-transsacral screws between June 2022 and June 2023. The patients were divided into navigation group (18 cases, using computer navigation system to assist screw implantation) and freehand group (23 cases, using C-arm X-ray fluoroscopy to guide screw implantation) according to the different methods of transiliac-transsacral screws placement. There was no significant difference in gender, age, body mass index, causes of injuries, Tile classification of pelvic fracture, days from injury to operation, usage of unlocking closed reduction technique between the two groups (P>0.05). The time of screw implantation, the fluoroscopy times, the guide wire adjustment times of each screw, and the incidence of complications were recorded and compared between the two groups. The position of the transiliac-transsacral screw was scanned by CT within 2 days after operation, and the position of the screw was classified according to Gras standard. ResultsThe operation was successfully completed in both groups. The time of screw implantation, the fluoroscopy times, and the guide wire adjustment times of each screw in the navigation group were significantly less than those in the freehand group (P<0.05). There were 2 cases of incision infection in the freehand group, and the incision healed by first intention after active dressing change; there was no screw-related complication in the navigation group during operation and early period after operation; the difference in incidence of complications between the two groups (8.7% vs. 0) was not significant (P=0.495). According to the Gras standard, the screw position of the navigation group was significantly better than that of the freehand group (P<0.05). ConclusionCompared with the traditional freehand method, the computer navigation system assisted transiliac-transsacral screws internal fixation in the treatment of posterior pelvic ring injuries has advantages of improving the accuracy of screw implantation and reducing radiation damage and the time of screw implantation.
ObjectiveTo summarize experience of laparoscopy combined with choledochoscopy common bile duct exploration for patients with schistosomiasis liver cirrhosis with common bile duct stones. MethodThe clinical data of 45 patients with schistosomiasis liver cirrhosis combined with common bile duct stones (liver function Child-Pugh grade A and B) admitted in this hospital from September 2012 to September 2015 were analyzed retrospectively. ResultsTwenty cases were successfully treated by laparoscopy combined with choledochoscopy (laparoscope group), 25 cases were treated by conventional open common bile duct exploration (laparotomy group). Two cases were converted to laparotomy due to bleeding during laparoscopic operation. The mean operation time, intraoperative bleeding, postopera-tive hospitalization time, and postoperative total complications rate had no significant differences between these two groups (P>0.05). There were 2 cases of pulmonary infection and 1 case of incision infection in the laparoscope group, and 1 case of grade A bile leakage and 1 case of pulmonary infection in the laparotomy group, there was no common bile duct stone residual in these two groups. ConclusionAlthough laparoscopic surgery is more difficult for schistosomiasis liver cirrhosis combined with common bile duct stones patients, it is safe and feasible. Appropriate perioperative management and precise laparoscopic and choledochoscopic operation are key to success of operation.
How to effectively repair esophageal fistulas, caused by esophageal perforation, rupture and anastomotic leakage after esophagectomy has always been a key problem for the digestive surgeon. Although there are many clinical treatment methods, the therapeutic effect is still completely unsatisfactory, especially when severe mediastinal purulent cavity infection is associated with the esophageal fistula. In recent years, foreign centers have promoted a new minimally invasive endoscopic treatment technology to repair the esophageal fistula, endoscopic vacuum-assisted closure therapy, with significantly curative effect. In this article, we will review the specific operation, advantages and disadvantages, as well as the clinical efficacy of endoscopic vacuum-assisted closure therapy in treating the esophageal fistulas, to provide a new therapeutic technique for esophageal fistulas and expand the new field of minimally invasive endoscopic therapy.
ObjectiveTo explore the effectiveness of self-made adjustable tractor for correction of inverted ni pple. MethodsBetween March 2005 and March 2011, 37 female patients with inverted ni pples (69 ni pples) underwent continuous traction with self-made adjustable tractor for 2 to 4 months. The age ranged from 18 to 46 years (mean, 23 years). Of 37 cases, 5 had unilateral inverted ni pple, and 32 had bilateral inverted ni pples, including 8 cases (15 ni pples) of mild inversion, 16 cases (30 ni pples) of moderate inversion, and 13 cases (24 ni pples) of severe inversion. The 2 cases (4 ni pples) recurred after traditional surgical method, and 1 case (2 ni pples) had infection because of severe inversion before traction. ResultsNo infection or hemodynamic disorder occurred during traction. All cases were followed up 6-12 months (mean, 8.2 months). Wound healed after traction in 1 patient (2 ni pples) with infection because of severe inversion; 2 recurrent cases (2 ni pples) were cured after re-traction; wire dislocation occurred in 1 case (1 ni pple), and was cured after changing traction position. The shape, sensation, and erectile function were normal after treatment with no scar. ConclusionContinuous traction with selfmade adjustable tractor is a good method for all the types of inverted ni pple. It is a simple, safe, effective, and minimally invasive method without scar.
