Objective To evaluate the role of curved-cutter-stapler in anus-preserving for low rectal cancer. Methods The clinical data of 32 patients with low rectal cancer from June 2007 to December 2008 who received low anterior resection and ultra low anterior resection by using curved-cutter-stapler were reviewed retrospectively. Results No operation death case, complete cutting and safe closure in all cases, one case was complicated with anastomotic leakage, and one case of rectovaginal fistula. Thirty patients were followed up 4 to 22 months after the operation, with an average time of 12.6 months, no hemorrhea of pelvic cavity and anastomotic stoma or anastomotic stenosis cases. Conclusion Curved-cutter-stapler has the advantages of complete cutting, safe closure and low complications, and easy being used in anus-preserving operation for low rectal cancer, which can increase the rate of anus-preserving.
Objective To compare the clinical effect of tissue selecting therapy stapler (TST) and procedure for prolapse and hemorrhoids (PPH) in treatment of hemorrhoid in Ⅲ-Ⅳ degree. Methods Clinical data of 80 cases of hemorrhoid in Ⅲ-Ⅳ degree who treated in The First Affiliated Hospital of Harbin Medical University from May 2015 to July 2015 were retrospectively collected. All the 80 cases were divided into TST group (n=40) and PPH group (n=40) according to the surgical types. The comparison of the clinical effect of 2 groups was performed. Results The operative time, hospital stay, intraoperative blood loss, anal fall bilge feeling score, postoperative pain score at 3 time points, and the incidence of anal secretions of TST group were lower or shorter than those corresponding indexes of PPH group (P<0.05). But there was no significant difference in cure rate, the incidence of urinary retention, the incidence of anal stenosis, the incidence of intractable pain, and satisfaction situation between the 2 groups (P>0.05). All of the cases were followed up for 3 months, during the follow-up period, no one suffered from rectal vaginal fistula, fecal incontinence, and recurrence. Conclusion TST and PPH both have satisfactory effect in treatment of hemorrhoid in Ⅲ-Ⅳ degree, but TST has advan- tages of less blood loss, shorter operative time, rapid postoperative recovery, and less pain.
Objective To evaluate the clinical efficacy of fistula repair by stapler technique in patients with cervical tracheoesophageal fistula. Methods Retrospective analysis of 8 patients with cervical tracheoesophageal fistula who accepted operative treatment in the Department of Thoracic Surgery, Lanzhou University Second Hospital from October 2014 to October 2016 was conducted. There were 5 males and 3 females at a mean age of 46.4±13.9 years ranging from 23 to 67 years. The fistula was induced by tracheal intubation in 4 patients, by esophageal foreign bodies in 2, by tracheal stent in 1 and by esophageal diverticulum in 1. The fistula was closed by stapler technique. The surgical effects were evaluated through Karnofsky performance score (KPS), image assessment, patient satisfaction score and assessment of improvement in feeding-induced bucking. Results The operations were performed successfully with time of 117.5±6.6 min and intraoperative blood loss of 60.0±7.0 ml. After the operations, the patients did not suffer incision bleeding and infection, hoarseness, dyspnea, drinking-induced bucking, fistula relapse, tracheoesophageal stenosis or any other complications, and no death occurred during the perioperative period. The chest X-ray test was performed 1 week later showed that the pulmonary infection disappeared, and only 1 patient suffered from esophageal stenosis 1 year later. The postoperative KPS score was 90.0±7.0 points, which significantly improved in contrast to preoperation (P<0.01). Postoperative pulmonary infection area reduced significantly (P<0.05), tracheoesophageal fistula disappeared, postoperative patients satisfaction rate was 90%, and assessment of feeding-induced bucking was excellent. Conclusion Using stapler technique to repair cervical tracheoesophageal fistula is safe, easy and useful, with less operation time and postoperative complications.
ObjectiveTo investigate the safety and feasibility of thoracoscopic lobectomy without mechanical suture.MethodsThe data of 28 consecutive patients (a non-mechanical suture group, 16 males and 12 females at age of 61.23±11.10 years) who underwent non-mechanical suture anatomic thoracoscopic lobectomy performed by the same surgeon from March 2015 to March 2018 were analyzed retrospectively, and 28 patients (18 males and 10 females at age of 59.45±13.39 years) who underwent completely anatomic thoracoscopic lobectomy with endoscopic stapler (a mechanical suture group) in the same period were matched. The clinical effectiveness of the two groups was compared.ResultsThe operation time between the non-mechanical suture group (136.30±53.46 min) and the mechanical suture group (109.63±44.61 min) showed a statistical difference (P<0.05). While in term of intraoperative bleeding volume (65.00 ml vs. 50.00 ml), postoperative thoracic drainage time (3.73 days vs. 3.56 days), thoracic drainage volume (538.60 ml vs. 563.70 ml), postoperative hospital stay (5.58 days vs. 5.35 days) and postoperative complication rate (5/28 vs. 6/28), there was no statistical difference between the two groups. Hospitalization expense was significantly different between the two groups (35 438.30 yuan vs. 51 693.60 yuan).ConclusionNon-mechanical suture thoracoscopic anatomic lobectomy is safe and feasible, and can significantly reduce the medical cost but prolong the operation time.
ObjectiveTo study the curative effect and postoperative anorectal dynamics change of tissue-selecting therapy stapler (TST) and procedure for prolapse and hemorrhoids (PPH) respectively combined with mixed Milligan-Morgan and lauromacrgol injection in the treatment of Ⅲ–Ⅳ degree mixed hemorrhoid.MethodsClinical data of 158 patients with Ⅲ–Ⅳdegree mixed hemorrhoid who received operation in the Department of Colorectal and Anal Surgery, Chaoyang Central Hospital, from May 2016 to March 2018 were analyzed retrospectively, the observation group (TST+Milligan-Morgan+lauromacrgol injection, 80 cases) and control group (PPH+Milligan-Morgan+lauromacrgol injection, 78 cases). The clinical efficacy, adverse reactions, postoperative complications and recurrence of the two groups were observed, and the changes of anorectal dynamic indexes before and after operation were observed.ResultsPostoperative symptoms of mixed hemorrhoid prolapse could be alleviated by 100% in both the observation group and the control group, and the relief rate of hematochezia was 93.8% and 92.3%, respectively, and the effective rate of 1 year after surgery was 97.5% and 94.9%, respectively. Comparison between the two groups showed no statistical difference (P>0.05). The operative time, intraoperative blood loss, VAS pain score and hospital stay of the observation group were all better than those of the control group (P<0.05). In terms of postoperative massive hemorrhage and anastomotic stenosis, although the incidence rate of the control group was higher than that of the observation group (3.8% vs. 1.3% and 2.6% vs. 0.0%, respectively), there was no statistical significance in the two groups (P>0.05). Postoperative anal drop, stool urgency, postoperative urinary retention and postoperative stimulation of anal papilla hypertrophy and proliferation complications were significantly better in the observation group than in the control group (P<0.05). The difference of maximum anal systolic pressure (MASP) in the two groups of patients between before and after surgery and the comparison of MASP results between the two groups after surgery showed no statistical differences (P>0.05). The differences of resting anal sphincter pressure (RASP) and rectal sensory threshold volume (RSTV) between before and after operation were not statistically significant (P>0.05). The difference of rectal maximum threshold volume (RMTV) value and the comparison of RASP, RSTV and RMTV value between the two groups after surgery showed that the observation group were superior to the control group and the differences were statistically significant (P<0.05).ConclusionsTST or PPH combined with Milligan-Morgan and lauromacrgol injection both are effective and minimally invasive methods for the treatment of Ⅲ–Ⅳ degree mixed hemorrhoid. However, the observation group has shorter operative time and hospital stay, less intraoperative blood loss, and lower postoperative pain score. What is more important is that the postoperative complications are less and the anal function is protected to the maximum extent, and the quality of life of patients after operation is greatly improved.
Objective To investigate the benefits of using a stapler tractor in the treatment of segmental bronchus during lung segmentectomy through detailed video replay analysis of surgical procedures. Methods We collected data from patients who underwent segmentectomy performed by the same surgical team in the Department of Thoracic Surgery, the First Affiliated Hospital of Nanjing Medical University, from November 2020 to August 2023. After excluding data that lacked analysis parameters, the remaining patients were divided into four groups based on the methods used for dissociating segmental bronchus: a stapler tractor group (group A), a stapler with bronchial stretching group (group B), a stapler only group (group C), and a silk ligature group (group D). Then, we compared baseline data and videotaped surgical details across all groups. Surgical details included the success rate of one-time segmental bronchus dissociation and severance, the time taken for successful one-time dissociation and severance of the segmental bronchus, the incidence of bleeding during bronchus dissociation, the conversion rate to thoracotomy during surgery, and surgical outcomes such as total operative time, postoperative hospitalization days, postoperative thoracic drainage volume, and pulmonary air leakage rate. Results The study included 325 patients (203 in the group A, 62 in the group B, 29 in the group C, and 31 in the group D). There was no statistically significant difference in baseline data among the four groups. However, significant differences were found in terms of total operation time, postoperative hospitalization days, intraoperative blood loss, segmental bronchial stump length, postoperative air leakage rate, hemorrhage rate during segmental bronchial dissociation, and conversion to thoracotomy rate among the four groups (P<0.05). ConclusionUsing a stapler tractor for dissociating segmental bronchus in lung segmentectomy results in shorter operative time, less risk of intraoperative bleeding, and less surgical complications. This study provides valuable evaluation methodologies through the analysis of video replay surgical details, contributing to the improvement of lung segmentectomy quality.
Compared to traditional suturing, lung stapling using automatic staplers offers advantages such as smaller trauma, faster wound healing, ease of operation, and lower complication rates, making it widely used in clinical practice. However, there are significant differences in bronchial tissue thickness at different anatomical locations, and the market is flooded with various types of staplers. Currently, there is a lack of recommended stapling schemes for bronchial staplers at different anatomical locations. This article reviews the development and application of automatic staplers and summarizes some types of staplers that are currently used in clinical practice, with the aim of promoting the formation of individualized stapler selection protocols for minimally invasive thoracic surgery based on the Chinese population.
