ObjectiveTo investigate the safety, feasibility and advantages of subxiphoid uni-portal thoracoscopic thymectomy.MethodsClinical data of 65 patients undergoing subxiphoid uni-portal thoracoscopic thymectomy in our hospital from September 2018 to March 2019 were retrospectively analyzed. They were treated as a subxiphoid surgery group, including 36 males and 29 females, aged 49.5 (29-71) years. The incision with the length of about 3 cm was located approximately 1 cm under the xiphoid process. From January 2016 to December 2017, 65 patients received intercostal uni-portal thoracoscopic thymectomy, who were treated as a control group, including 38 males and 27 females, aged 48.9 (33-67) years. All patients who were clinically diagnosed with thymic tumor before surgery were treated with total thymectomy. After surgery, expectoration and analgesia were used.ResultsThere was no statistically significant difference in general clinical data, lesion size, intraoperative blood loss, postoperative catheterization time, postoperative hospital stay and postoperative pathology between the two groups. All operations were successfully completed, and the patients in both groups recovered uneventfully after surgery. Visual analogue scale scores on the 1st, 3rd, 7th and 30th day after surgery in the subxiphoid surgery group were lower than those in the control group.ConclusionThe subxiphoid uni-portal thoracoscopic approach can achieve total thymectomy with less trauma and faster postoperative recovery.
With the upgrading of minimally invasive surgical concepts and laparoscopic equipment for gastric cancer, single-incision laparoscopic surgery (SILS) had emerged as a new focus of research in gastric cancer surgery. SILS offered advantages such as reduced damage, superior cosmetic outcomes, decreased postoperative pain, and faster recovery as compared with traditional laparoscopic gastrectomy. However, its level of difficulty limited its further promotion and application. Although numerous studies supported the safety and feasibility of SILS, more high-level evidence-based medical research was required to endorse its widespread use. The author reviewed the development history, current status, and prospects of SILS laparoscopic gastric cancer surgery.
Objective To investigate the short-term effectiveness of uni-portal non-coaxial spinal endoscopic surgery (UNSES) via crossing midline approach (CMA) in the treatment of free lumbar disc herniation (FLDH). MethodsBetween March 2024 and June 2024, 16 patients with FLDH were admitted and treated with UNSES via CMA. There were 9 males and 7 females with an average age of 55.1 years (range, 47-62 years). The disease duration was 8-30 months (mean, 15.6 months). The pathological segments was L3, 4 in 4 cases, L4, 5 in 5 cases, and L5, S1 in 7 cases. The preoperative pain visual analogue scale (VAS) score was 6.9±0.9 and the Oswestry disability index (ODI) was 57.22%±4.16%. The operation time, intraoperative bleeding volume, postoperative hospital stay, and incidence of complications were recorded. The spinal pain and functional status were evaluated by VAS score and ODI, and effectiveness was evaluated according to the modified MacNab criteria. CT and MRI were used to evaluate the effect of nerve decompression. ResultsAll 16 patients underwent operation successfully without any complications. The operation time was 63-81 minutes (mean, 71.0 minutes). The intraoperative bleeding volume was 47.3-59.0 mL (mean, 55.0 mL). The length of hospital stay after operation was 3-4 days (mean, 3.5 days). All patients were followed up 1-3 months, with 15 cases followed up for 2 months and 14 cases for 3 months. The VAS score and ODI gradually decreased over time after operation, and there were significant differences between different time points (P<0.05). At 3 months after operation, the effectiveness was rated as excellent in 12 cases and good in 2 cases according to the modified MacNab criteria, with an excellent and good rate of 100%. CT and MRI during follow-up showed a significant increase in the diameter and cross-sectional area of the spinal canal, indicating effective decompression of the canal. ConclusionWhen using UNSES to treat FLDH, choosing CMA for nerve decompression has the advantages of wide decompression range, large operating space, and freedom of operation. It can maximize the preservation of the articular process, avoid fracture and breakage of the isthmus, clearly display the exiting and traversing nerve root, and achieve good short-term effectiveness.
Single-incision laparoscopic sleeve gastrectomy (SILSG) was first described in 2008, which could effectively control excess body weight and treat metabolic diseases relevant to obesity in a long term. Over more than a decade of refinement and technical advancement, precise and standardized surgical techniques have become critical for ensuring treatment efficacy and reducing the rate of postoperative complications. Thus, this review summarizes the evolution of SILSG, further understanding and emphasizing the importance of standardized and precise surgical procedures.
Objective To investigate the effectiveness of one-hole split endoscope (OSE) technique in the treatment of single segment lumbar spinal stenosis (LSS). Methods The clinical data of 32 single segment LSS patients treated with OSE technique for simple spinal canal decompression between January 2022 and December 2022, who met the selection criteria, were retrospectively analysed. There were 18 males and 14 females, the age ranged from 45 to 82 years, with an average of 65.1 years. The disease duration was 9-72 months, with an average of 34.9 months. The surgical segments included L3, 4 in 3 cases, L4, 5 in 19 cases, and L5, S1 in 10 cases. The incision length, operation time, intraoperative blood loss, intraoperative radiation exposure frequency, postoperative mobilization time, and the area of the patient’s lesion segment dural sac before operation and at 1 month after operation were recorded. Low back pain and leg pain were assessed by visual analogue scale (VAS) score before operation and at 3 days, 3 months, and 12 months after operation; functional recovery was assessed by Oswestry disability index (ODI) before operation and at 3 months and 12 months after operation; the effectiveness was assessed by modified MacNab criteria at last follow-up. Results All 32 patients successfully completed the operation, with an average incision length of 2.05 cm, an average operation time of 88.59 minutes, an average intraoperative blood loss of 46.72 mL, an average intraoperative radiation exposure frequency of 3.84 times, and an average postoperative mobilization time of 11.66 hours. All patients were followed up 12-16 months, with an average of 13.5 months. One patient experienced lower limb numbness, pain, and decreased muscle strength after operation, while the remaining patients did not experience complications such as dural tear or important nerve damage. The VAS scores of low back pain and leg pain and ODI in patients at various time points after operation were significantly better than preoperative ones, and each indicator further improved with time. The differences between time points were significant (P<0.05). At 1 month after operation, the area of the patient’s lesion segment dural sac was (123.13±19.66) mm2, which significantly increased compared to preoperative (51.25±9.50) mm2 (t=−18.616, P<0.001). At last follow-up, the improved MacNab criteria were used to evaluate the effectiveness, with 18 cases achieving excellent results, 11 cases being good, and 3 cases being fair, with an excellent and good rate of 90.6%. ConclusionThe effectiveness of using OSE technique for simple spinal canal decompression treatment of single segment LSS is satisfactory, with the advantages of minimal surgical trauma and fast recovery.
ObjectiveTo evaluate the security and feasibility of transumbilical laparoendoscopic single-site cholecystectomy (TULESC) with conventional laparoscopic instruments. MethodsThe clinical data of 62 adult patients undergoing TULESC between October 2011 and June 2013 were analyzed retrospectively. There were 13 males and 49 females aged between 22 and 70 years old averaging 40±15. Forty-nine patients suffered from chronic cholecystitis with cholelithiasis, 10 from asymptomatic cholelithiasis and 3 from cholecystic polyposis. A single arc incision was cut on the edge of the umbilicus, and two 10 mm Trocars and one 5 mm Trocar were placed by puncture. Cholecystectomy was performed with conventional laparoscopic instruments and equipment. ResultsAll the 62 patients underwent TULESC successfully without severe complications such as bile leakage or biliary injury. The operation time was 20-70 minutes with the average of (40±15) minutes; The blood loss was 5-40 mL with the average of (15±10) mL. All the patients were discharged from the hospital within 3 to 7 days after surgery, averaging 4.0±1.0. During the 1 to 12-month follow-up (averaging 3 months), there was no obviously visible scars on the abdominal wall and the aesthetic effect was significant. ConclusionTULESC with conventional laparoscopic instruments and equipment is safe, feasible and cosmetic.
Objective To compare the clinical efficacy and safety of suturesuspension single hole laparoscopic cholecystectomy and traditional laparoscopic cholecystectomy (LC) in the treatment of gallbladder disease. Methods A total of 86 cases who got treatment in our hospital from February 2014 to July 2015 were collected prospectively, and then 86 cases were divided into 2 groups: 43 cases of control group underwent LC and 43 cases of experimental group underwent suturesuspension single hole laparoscopic cholecystectomy. Clinical efficacy and safety of the two groups were compared. Results ① Complication. No one suffered from bile duct injury, bile leakage, bile duct stricture, and umbilical hernia; but there were 2 cases suffered from complications in control group, including 1 case of abdominal pain and 1 case of bloating, and the morbidity was 4.65% (2/43). The morbidity of experimental group was 0, there was no significant difference between the 2 groups in the morbidity (P>0.05). During the follow-up period, 1 case suffered from long-term compilation in experimental group, and 2 cases in normal group, there was no significant difference in the long-term complication between the 2 groups (P>0.05). ② Operation and hospitalization. The blood loss and operation time in the experimental group were lower than those of the control group (P<0.05), but there was no significant difference in the hospital stay and hospitalization cost between the 2 groups (P>0.05). ③ Postoperative electrolytes, liver and kidney function. The levels of Na+ and K+ in the experimental group were higher than those of the control group (P<0.05), and the levels of alanine aminotransferase and aspartate aminotransferase were lower than those of control group (P<0.01), but there was no significant difference in the blood urea nitrogen and serum creatinine between the 2 groups (P>0.05). ④ The recovery of gastrointestinal function after surgery. The anal exhaust time and bowel sounds recovery time in experimental group were shorter than those of the control group (P<0.01). Conclusion Suturesus-pension single hole laparoscopic cholecystectomy in the treatment of gallbladder disease is safe, effective, and minimally invasive, and it has little disturbance on gastrointestinal function and liver function, which is worthy of clinical application.
Objective To investigate the feasibility and safety of uniportal video-assisted thoracic surgery (VATS) for primary lung cancer. Methods We retrospectively analyzed the clinical data of 95 primary lung cancer patients in our hospital between January 2014 and January 2015. The patients were divided into an observation group (45 patients) and a control group (50 patients). Standard thoracoscopy lobectomy was used in the control group. Uniportal thoracoscopy lobectomy was used in the trial group. The parameters of the two groups were observed. Results The surgeries of the two groups were successfully completed. There was no statistical difference in operative time, intraoperative transit rate, blood loss, number of lymph node dissection, thoracic drainage and pathology Ⅰ, Ⅱ period (P>0.05). Postoperative drainage tube time, postoperative hospital stay, postoperative pain in the observation group were better than those in the control group (P<0.05). But postoperative drainage time in the observation group was longer than that in the control group (P<0.05). Also, the total hospital costs, especially on the use of expensive consumables, during surgery in the observation group was higher. And there was a higher risk of delayed incision healing or airway injury (P<0.05) in the observation group. One death in the control group during perioperative period occurred. Conclusion Uniportal VATS operation applied in radical operation for lung cancer is safe and feasible. It accelerates postoperative turnover, reduces postoperative pain. But there is a higher risk for airway injury or delayed wound healing, and an increase in use of medical consumptive stuff.
