ObjectiveTo summarize the data of robotic hysterectomy in patients with large and super-large uterus in single center, and explore the relevant clinical experience and advantages of robotic surgery.MethodsThe medical records of the patients with large uterus caused by gynecological diseases who underwent robotic hysterectomy in the Chinese PLA General Hospital from January 2016 to December 2018 were retrospectively analyzed. The patients with uterine size from 12 to 16 weeks of gestation were divided into large uterus group and those with uterine volume larger than 16 weeks of gestation were divided into super large uterus group.ResultsA total of 62 patients were included, including 28 in the large uterus group with the average uterus size of (14.3±2.1) gestational weeks, and 34 in the super large uterus group with the average uterus size of (19.9±2.8) gestational weeks. There was no significant difference in mean age, body mass index, history of abdominal surgery or diagnostic composition between the two groups (P>0.05), except for the size of the uterus (t=8.772, P<0.001). The operation time in the large uterus group was less than that in the super-large uterus group [(75.4±22.6) vs. (91.7±27.8) min; t=2.495, P=0.015]. The incidence of complications after robotic hysterectomy was 14.5% (9/62) in the 62 patients, including 14.3% (4/28) in the large uterus group and 14.7% (5/34) in the super-large uterus group. There was no significant difference in the amount of bleeding, blood transfusion rate, ratio of conversion to open surgery, average hospitalization days or incidence of postoperative complications between the two groups (P>0.05).ConclusionsRobotic hysterectomy has the advantages of flexible manipulator, 3-D operative field of vision and stability of manipulation. In addition, increased uterine volume does not lead to increased surgical trauma, nor apparently affect the prognosis.
ObjectiveTo assess the feasibility of the treatment of unresectable late pancreatic cancer with laparoscopic choledochojejunostomy and gastric bypass. MethodsFrom June 2000 to December 2003, laparoscopic choledochojejunostomy and gastric bypass were successfully performed in 15 patients with unresectable late pancreatic cancer. Endoscopic nosobiliary drainage (ENBD) was performed before the operation. ResultsAll procedures were completed laparoscopically. Jaundice and hepatic function of the patients were obviously improved after the bypass. Oral nutrition was recovered after operation. The mean operative time was (100±26) min (range 70-200 min); the mean operative blood loss was (60±15) ml (range 30-120 ml); the bowel function recovery was on the 3rd-5th postoperative day; the average hospital stay was (8.1±0.7) days (range 6-13 days). Incision infection ocurred in one patient. No operative complications occurred in other patients. ConclusionTreatment of unresectable late carcinoma of the pancreas with laparoscopic choledochojejunostomy and gastric bypass aided by ENBD is a minimally invasive technique with less postoperative pain，shorter hospital stay, lower procedurerelated morbidity,and better oral nutrition. The life quality of patients with late pancreatic cancer can be obviously improved.

Objective To compare the short-term effectiveness of minimally invasive surgery-transforaminal lumbar interbody fusion (MIS-TLIF) versus open-TLIF in treatment of single-level lumbar degenerative disease. Methods Between February 2010 and February 2011, 147 patients with single-level lumbar degenerative diseases underwent open-TLIF in 104 cases (open-TLIF group) and MIS-TLIF in 43 cases (MIS-TLIF group), and the clinical data were analyzed retrospectively. There was no significant difference in gender, age, disease type, lesion level, disease duration, preoperative visual analogue scale (VAS), and preoperative Oswestry disability index (ODI) between 2 groups (P gt; 0.05). The operation time, intraoperative radiological exposure time, intra- and post-operative blood loss, postoperative hospitalization time, and postoperative complications were compared between 2 groups. The VAS score and ODI were observed during follow-up. The imaging examination was done to observe the bone graft fusion and the locations of internal fixator and Cage. Results There was no significant difference in operation time between 2 groups (t=0.402, P=0.688); MIS-TLIF group had a decreased intra- and post-operative blood loss, shortened postoperative hospitalization time, and increased intraoperative radiological exposure time, showing significant differences when compared with open-TLIF group (P lt; 0.05). Cerebrospinal fluid leakage (2 cases) and superficial infection of incision (2 cases) occurred after operation in open-TLIF group, with a complication incidence of 3.8% (4/104); dorsal root ganglion stimulation symptom (3 cases) occurred in MIS-TLIF group, with a complication incidence of 7.0% (3/43); there was no significant difference in the complication incidence between 2 groups (χ2=0.657, P=0.417). The patients were followed up 18-26 months (mean, 21 months) in MIS-TLIF group, and 18-28 months (mean, 23 months) in open-TLIF group. The VAS scores and ODI of 2 groups at each time point after operation were significantly improved when compared with those before operation (P lt; 0.05). There was no significant difference in VAS score between 2 groups at discharge and 3 months after operation (P gt; 0.05); VAS score of MIS-TLIF group was significantly lower than that of open-TLIF group at last follow-up (t= — 2.022, P=0.047). At 3 months and last follow-up, no significant difference was found in the ODI between 2 groups (P gt; 0.05). The imaging examination showed good positions of Cage and internal fixator, and bone graft fusion in 2 groups. Conclusion The short-term effectiveness of MIS-TLIF and open-TLIF for single-level degenerative lumbar diseases was similar. MIS-TLIF has the advantages of less invasion and quick recovery, but the long-term effectiveness needs more observation.
Objective To investigate the short-term effectiveness of total hip arthroplasty (THA) with SL-PLUS MIA femoral stem prosthesis by comparing with the SL-PLUS prosthesis. Methods Retrospective analysis was made on the clinical data of 33 patients (38 hips) undergoing THA with SL-PLUS MIA femoral stem prosthesis (trial group) between June and December 2011, which was compared with those of 35 patients (40 hips) with SL-PLUS prosthesis (control group) during the same period. There was no significant difference in gender, age, disease duration, etiology, preoperative range of motion (ROM) of hip, and preoperative Harris score between 2 groups (P gt; 0.05). The incision length, operation time, and intraoperative blood loss were recorded during operation. The improvement of hip joint function was evaluated according to Harris score criteria. The ROM of hip was measured, and the X-ray film was taken to observe the position of prosthesis. Results Trial group had shorter incision length, less operation time, and less intraoperative blood loss than control group, showing significant differences (P lt; 0.05). All wounds healed by first intention. All patients were followed up 10-16 months (mean, 13.6 months). During follow-up, 5 cases (5 hips) of control group and 3 cases (3 hips) of trial group still had pain of hips. At last follow-up, the ROM of hip was (152.48 ± 9.68)° in trial group and (152.16 ± 8.18)° in control group, the Harris score was 91.4 ± 2.9 in trial group and 90.9 ± 1.8 in control group; there were significant differences when compared with preoperative values (P lt; 0.05), but no significant difference was found between 2 groups (P gt; 0.05). X-ray films showed good position of the prosthesis with no displacement, loosening, or subsidence in both groups. Conclusion SL-PLUS MIA femoral stem prosthesis has less surgical trauma and blood loss than SL-PLUS prosthesis during THA. The short-term effectiveness is satisfactory, but the long-term effectiveness still needs further observation.
Objective To summarize diagnosis and treatment outcomes of coronary arterial fistulas （CAFs） so as to improve surgical results. Methods Clinical data of 23 patients with CAFs who underwent surgical repair in Xinhua Hospital，School of Medicine，Shanghai Jiaotong University from July 2006 to January 2013 were retrospectively analyzed. There were 15 male and 8 female patients with their age of 35.4±8.7 years. CAFs originated from left anterior descendingartery in 7 patients，right coronary artery in 13 patients，dual coronary arteries in 1 patient，left main coronary artery in 1 patient，and obtuse marginal artery in 1 patient. CAFs drained into pulmonary artery in 16 patients，right ventricle in 5patients，and right atrium in 2 patients. Twelve patients received surgical repair under off-pump condition with beating heart，and the other 11 patients underwent surgery under cardiopulmonary bypass （CPB）. Surgical techniques included extracardiacgasket interrupted suture ligation，intracardiac mattress suture ligation，intracardiac gasket interrupted suture for fistula repair，and a combination of intracardiac suture ligation and extracardiac repair. Results There was no in-hospital death or seriouspostoperative complication in this group. For the 11 patients undergoing surgical repair under CPB，average CPB time was 78.6±7.4 minutes，and average aortic cross-clamping time was 39.0±5.9 minutes. Postoperatively，patients’ heart functionrecovered well，their symptoms disappeared，and there was no myocardial ischemia or residual fistula. Twelve patients werefollowed up at the outpatient department and via telephone for 3 months to 6 years after discharge. During follow-up，theirheart function all recovered well，and echocardiogram detected no abnormality. There was no late death，myocardial ischemiaor residual fistula. Conclusion All CAFs patients need early surgical repair once their diagnosis is clear. Appropriate surgical strategies should be chosen according to the characteristics of pathological anatomy and associated intracardiaclesions. Surgical outcomes are satisfactory.
Objective To assess the feasibility and adequacy of Harmonic Scalpel in a totally laparoscopic total mesorectal excision (TME) and low,ultralow,colo-anal anastomoses for rectal cancer. Methods Excision of the mesorectum and low，ultralow site anastomoses were performed laparoscopically on 30 patients with low rectal cancer based on the concept of TME. Results All 30 TME were successfully completed by laparoscopic approach, and no one was converted to open procedures. A cholecystectomy and/or an ovariotomy were meanwhile performed laparoscopically for 3 patients with rectal cancer,and 1 patient with chronic cholesyctitis, gallstone,ovarian cyst and torsion of the ovary. The operation time was 155 min (115-320 min). Operative blood loss was 20 ml (5-80 ml).The time of bowel function returned and the time to resume postoperative diet was 1-2 days after the operation. Fourteen patients had postoperative analgesic requirement. Average hospital stay was 8 days (5-14 days) and there were no intraoperative and postoperative complications in all 30 patients.Conclusion Laparoscopic excision of the mesorectum and low,ultralow,coloanal anastomoses with Harmonic Scalpel for low rectal cancer is a perspective minimally invasive technique, which is feasible, safe, effective and has dramatic high rates of sphincter preservation with decreased postoperative pain, rapid recovery.
Objective To compare the difference of traumatic related index in serum and its significance between minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) and open TLIF. Methods Sixty patients were enrolled by the entry criteria between May and November 2012, and were divided into MIS-TLIF group (n=30) and open TLIF group (n=30). There was no significant difference in gender, age, type of lesions, disease segment, and disease duration between 2 groups (P gt; 0.05). The operation time, intraoperative blood loss, and postoperative hospitalization time were recorded, and the pain severity of incision was evaluated by visual analog scale (VAS). The serum levels of C-reactive protein (CRP) and creatine kinase (CK) were measured at preoperation and at 24 hours postoperatively. The levels of interleukin 6 (IL-6), IL-10, and tumor necrosis factor α (TNF-α) in serum were measured at preoperation and at 2, 4, 8, and 24 hours after operation. Results The operation time, intraoperative blood loss, and postoperative hospitalization time of MIS-TLIF group were significantly smaller than those of open TLIF group (P lt; 0.05), and the VAS score for incision pain in MIS-TLIF group was significantly lower than that of open TLIF group at 1, 2, and 3 days after operation (P lt; 0.05). The levels of CRP, CK, IL-6, and IL-10 in MIS-TLIF group were significantly lower than those in open TLIF group at 24 hours after operation (P lt; 0.05), but there was no significant difference between 2 groups before operation (P gt; 0.05). No significant difference was found in TNF-α level between 2 groups at pre- and post-operation (P gt; 0.05). Conclusion Compared with the open-TLIF, MIS-TLIF may significantly reduce tissue injury and systemic inflammatory reactions during the early postoperative period.
Objective To investigate the effectiveness of minimally invasive transforaminal lumbar interbody fusion (TLIF) assisted with microscope for lumbar degenerative disease. Methods Retrospective analysis was made on the clinical data of 82 patients with lumbar degenerative disease (minimally invasive group) undergoing minimally invasive TLIF assisted with microscope between January 2010 and June 2011, which was compared with those of 76 patients (traditional group) undergoing traditional open TLIF. There was no significant difference in age, gender, disease duration, disease type, lesion level, preoperative visual analogue scale (VAS), and preoperative Oswestry disability index (ODI) between 2 groups (P gt; 0.05). The perioperative related parameters, radiography index, and effectiveness were documented and compared. Results There was no significant difference in operation time and intraoperative radiological exposure time between 2 groups (P gt; 0.05), but intraoperative blood loss and postoperative drainage volume in the minimally invasive group were significantly less than those in the traditional group (P lt; 0.05). Dural tear occurred in 2 patients of the traditional group. Superficial infection of incision occurred in 1 case in each group, respectively; and primary healing of incision was obtained in the other patients. All patients were followed up 12-28 months (mean, 18 months). No failure of internal fixation occurred. Radiological analysis showed that the bone graft fusion rate was 96.1% (73/76) in the traditional group and 95.1% (78/82) in the minimally invasive group at last follow-up, showing no significant difference (χ2= 0.012 2, P= 0.912 0). The postoperative ODI and VAS score were significantly improved when compared with preoperative ones in 2 groups (P lt; 0.05); the ODI of the minimally invasive group were significantly better than those of the traditional group at 3 months (t= — 11.941 1, P=0.000 0), and the VAS score of the minimally invasive group was significantly lower than that of the traditional group at 1 day and 3 months (P lt; 0.05); but no significant difference was found in ODI and VAS score between 2 groups at 1 year and last follow-up (P gt; 0.05). Conclusion Minimally invasive TLIF is an effective method to treat lumbar degenerative disease. This procedure is safe and reliable because it has less injury, less blood loss, and milder pain than the traditional open TLIF, and the short-term effectiveness is comparable in 2 procedures.
