ObjectiveTo investigate the effectiveness of debridement and single-incision vertebral screw-rod fixation combined with pedicle screw-rod fixation and autograft bone fusion in treatment of thoracolumbar tuberculosis. MethodsBetween January 2008 and October 2010, 22 patients with thoracolumbar tuberculosis were treated by debridement and single-incision vertebral screw-rod fixation combined with pedicle screw-rod fixation and autograft bone fusion, and were given anti-tuberculosis therapy after operation. Of 22 patients, 14 were male and 8 were female with an average age of 42 years (range, 18-66 years). The disease duration was 2-16 months (mean, 6 months). Sixteen double-segment lesions included T7, 8 in 3 cases, T8, 9 in 1 case, T9, 10 in 3 cases, T11, 12 in 2 cases, L1, 2 in 4 cases, and L3, 4 in 3 cases; 6 three-segment lesions included T7-9 in 2 cases, T11-L1 in 1 case, and L2-4 in 3 cases. Preoperative visual analogue scale (VAS) score was 7.50 ± 0.63. According to Frankel classification of America Spinal Injury Association (ASIA), 2 cases were rated as grade B, 4 cases as grade C, 9 cases as grade D, and 7 cases as grade E. ResultsTwenty-two patients were followed up 15-36 months (mean, 25.2 months). Wound infection occurred in 1 case and was cured after corresponding treatment; incision healed by first intention in other patients. No loosening or breakage of internal fixator was found; the patients had no deteriorations in spinal cord injury or cerebrospinal fluid leakage. X-ray films and CT showed obvious bone fusion in the intervertebral space. The time of bone fusion was 3-6 months (mean, 5.2 months). The erythrocyte sedimentation rate after operation was significantly lower than that before operation (P lt; 0.05). The VAS scores were significantly improved to 2.90 ± 1.00 at 2 weeks after operation and 2.60 ± 0.81 at last follow-up (P lt; 0.05). At last follow-up, nerve function was significantly improved. According to Frankel classification, 2 cases were rated as grade C, 5 cases as grade D, and 15 cases as grade E. ConclusionSingle-incision vertebral screw-rod fixation combined with pedicle screw-rod fixation for thoracolumbar tuberculosis is a stable and minimally invasive method. However, the long-term effectiveness need further follow-up.
Objective To evaluate the effect of posterior lumbar interbody fusion (PLIF) using single incision via MAST Quadrant retractor in the management of lumbar spondylolisthesis. Methods From July 2008 to June 2009, 20 cases of lumbar spondylolisthesis were treated with posterior lumbar interbody fusion via MAST Quadrant retractor using single incision,including 2 cases of degenerative spondylolisthesis and 18 cases of isthmic spondylolisthesis. There were 8 males and 12 females aged from 34 to 62 years (average 45.5 years). The disease course was 1 to 6 years (mean 34.5 months). The spondylol isthesis locations were L4,5 in 8 cases and L5, S1 in 12 cases. According to Meyerding classification, all cases were classified as degree I. The Visual Analogue Scale (VAS) score was (6.6 ± 1.2) points. The operative time, the blood loss, and the therapeutic effects were recorded. Results The operative time was (155 ± 23) minutes and the amount of blood loss was (360 ± 102) mL. The hospitalization time were (12.0 ± 3.4) days. All incisions healed by first intention. X-ray films showed spondylolisthesis reduction immediately after operation. All patients were followed up 14.3 months on average (from 9 to 20 months). The VAS score decreased to (1.6 ± 2.3) points at the last follow-up, showing significant difference when compared with that of preoperation (P lt; 0.05). The X-ray films showed that lumbar interbody fusion was achieved in all the patients. No lossening, breakage, and displacement of pedicle screw fixation was observed. According to Nakai standard, the results were excellent in 18 cases and good in 2 cases at the last follow-up. Conclusion As long as the indication is strictly chosen, PLIF via MAST Quadrant retractor is a safe, effective, and minimally invasive surgical technique in treating lumbar spondylolisthesis.

ObjectiveTo summarize the procedure of transumbilical single incision laparoscopic surgery (SILS) with conventional laparoscopic instruments for different tumor diameter and different site of gastric stromal tumor. MethodThe clinical data, intraoperative procedure, and postoperative recovery of 34 patients with gastric stromal tumor from December 2009 to February 2014 in this hospital were analyzed retrospectively. ResultsThe transumbilical SILS was performed successfully in all the 34 patients.Among these patients, the wedge resection of stomach was perfor-med in 27 patients, distal subtotal gastrectomy was performed in 6 patients, distal subtotal gastrectomy complicated with multivisceral resection was performed in 1 patient.The pathology confirmed that the diameter of tumors was from 0.6 cm to 10.0 cm (average 3.4 cm).The resection margins were tumor free.The risk assessment showed that tumors with extremely low risk were in 9 cases, low risk were in 17 cases, intermediate risk were in 6 cases, high risk were in 2 cases.During surgery, 9 tumors were located on the fundus of stomach, 6 tumors on the gastric greater curvature, 7 tumors on the gastric lesser curvature, 2 tumors on the anterior and posterior wall of the stomach respectively, 3 tumors on the cardia below, 4 tumors on the gastric antrum, tumor invaded the surrounding organs in 1 case.There was no conversion to open or conventional laparoscopic surgery.no intraoperative or postoperative complications were experi-enced in all the patients except one was postoperative intraperitoneal bleeding and one was incision infection.All the patients were followed for an average of 25 months (range 3-49 months), there was no evident recurrence of disease. ConclusionsThe transumbilical SILS for gastric stromal tumor is a feasible and safe technique when performed by an experienced laparoscopic surgeon.The suitable procedure of SILS should be selected for gastric stromal tumor according their different size and location.
ObjectiveTo compare clinical outcome between single-incision laparoscopic subtotal gastrectomy (SILSG) versus laparoscopy-assisted subtotal gastrectomy (LASG) in treatment of benign gastric ulcer and duodenal ulcer. MethodsClinical data of 37 patients with benign gastric ulcer or duodenal ulcer who underwent laparoscopic subtotal gastrectomy between Jan. 2008 and Feb. 2015 at Shengjing Hospital of China Medical University was collected retrospectively. Among them, 15 patients underwent SILSG and 22 patients underwent LASG. Demographic, intraoperative, and postoperative data was analyzed and compared between the 2 groups. ResultsThe operative time of SILSG group was significantly longer than that of LASG group (P < 0.050). However, the postoperative hospital stay was significantly shorter (P < 0.050), and the total patient scar assesment scale (PSAS) score was significantly lower (P < 0.050) in the SILSG group than those of LASG group. There was no significant difference between the 2 groups with respect to other variables (P > 0.050), such as conversion rate, intraoperative blood loss, postoperative exhaust time, incidence of complication, and visual analog scale score of pain. All patients received postoperative follow up, and the period ranged from 6 months to 25 months, with a median of 11 months. During the follow up period, no one suffered from incision hernia and recurrence of ulcer. ConclusionCompared with LASG, SILSG is a technically feasible procedure with better cosmesis and equivalent curability.
Objective To explore the feasibility of single incision laparoscopic cholecystectomy in the treatment of acute cholecystitis, and to provide evidence based medicine for clinical treatment. Methods A total of 160 cases of acute cholecystitis who received treatment in our hospital from Jan. 2012 to Dec. 2015 were randomly divided into single incision group (n=80, received single incision laparoscopic cholecystectomy) and three incisions group (n=80, received three incisions laparoscopic cholecystectomy). The clinical and laboratory indexes were compared between the 2 groups. Results Compared with the three incisions group, there were statistically significant differences in the operation time, incision pain score, and subjective satisfaction, which were better in single incision group (P<0.05). But there was no significant difference in the blood loss, bed time, anal exhaust time, recovery time of intestinal peristalsis, hospitalization time, incidence of complication (including abdominal infection, bile duct injury, biliary fistula, and incision infection), ratios of T cell subsets (including CD3, CD4, and CD8 T cell), levels of immunoglobulin (including IgA, IgG, and IgM), and level of C reactive protein (P>0.05). Conclusions The effectiveness of single incision laparoscopic cholecystectomy is as good as three incisions laparoscopic cholecystectomy, but this single incision laparoscopic surgery is difficult, and its indications should be cautious. Single incision laparoscopic cholecystectomy is more suitable for patients undergoing elective cholecystectomy.
ObjectiveTo investigate the value of single incision laparoscopic cholecystectomy in the operation of benign diseases of the gallbladder in day surgery.MethodThe clinical data of 105 patients underwent the single incision laparoscopic cholecystectomy in the Day Operation Center of Zhengzhou Central Hospital of Zhengzhou University from March 2017 to December 2018 were retrospectively analyzed.ResultsThe single incision laparoscopic cholecystectomies were successfully performed in 105 patients with benign gallbladder diseases, including 65 cases of gallbladder stones, 26 cases of gallbladder polyps, 14 cases of gallbladder adenomyosis; 45 cases of men and 60 cases of women. In all cases, no incision was increased or no case was converted to laparotomy. No bile duct injury and intra-abdominal bleeding happened during the operation. All patients were discharged overnight (no more than 24 h) after the surgery and without delayed discharge and re-admission. The intraoperative blood loss was (10.3±3.5) mL, and the operation time was (55.0±25.5) min (from laparoscopy to gallbladder removal). The postoperative pain score was 1–2 and 0–1 on day 1 and on day 3 after the surgery, respectively. The postoperative incision cosmetic satisfaction score on month 6 after the operation was 4.5±0.5.ConclusionSingle incision laparoscopic cholecystectomy is safe and feasible for benign gallbladder disease during day surgery.
