Long-term pulmonary repair in rat lungs after sublobar resection: electrocautery versus stapler methods.

We investigated and compared the long-term (6-month) histologic changes in a rat model of sublobar resection created using electrocautery or stapler techniques. Nine-week-old male rats were anesthetized and intubated; thoracotomy with sublobar resection was performed in the right middle lobe using electrocautery or stapler techniques. Histological examination was performed at 2, 4, 8, 12, and 24weeks post-surgery to assess long-term effects on lung tissue repair and morphologic changes. Lung expansion and alveolar epithelial cell proliferation were evaluated by measuring the mean linear intercept and counting the number of alveolar type I and II cells. The electrocautery group showed signs of lung self-repair at the resected area over time, with inflammatory cell infiltration followed by growth of vessels and bronchioles. Mesothelial cells covered the resected area by 2weeks; elastic fibers gradually connected from both sides by 24weeks. Lung expansion, measured by mean linear intercept, was initially small below the electrocautery resection area at 2weeks but recovered from 4 to 24weeks. The stapler group showed persistently small mean linear intercept over time. In the electrocautery group, the number of alveolar type II cells was higher just below the resection than in other areas from 2 to 24weeks, followed by alveolar type I cells (4 to 24weeks). The stapler group showed a transient alveolar type II cell increase at 2weeks. Compared to the stapler technique, electrocautery mayprovide advantages for postoperative lung repair by promoting lung expansion and alveolar epithelial cell proliferation.

Rectal stenosis after circular mechanical anastomosis; the influence of stapler size.

The incidence of benign anastomotic stenosis (BAS) after radical surgery for rectal cancer ranges from 2 to 30%. There are few data regarding the factors related to its occurrence. One of these factors is the diameter of the circular mechanical staplers (CMS) used. Observational study with prospective data recording of consecutive patients with non-disseminated rectal cancer operated on at two hospitals with special dedication to rectal cancer. Patients underwent low anterior resection (LAR) of the rectum with colorectal anastomosis created using CMS of diameters of either 28-29 or 31-33mm. The primary endpoint was BAS. Secondary variables were demographic and patient-dependent data, and preoperative, intraoperative, immediate postoperative and mid-term data. The incidence of BAS was compared in the groups in which the different stapler diameters were used. Between 2012 and 2022, 239 patients were included. BAS was recorded in 39 (16.3%). In the analysis of factors related to its occurrence, the only significant variable was stapler diameter (p = 0.002, 95% CI 7.27-23.53), since rates of BAS were lower in the 31-33mm group. Similarly, in the logistic regression analysis, stapler size was not associated with postoperative complications or anastomotic dehiscence (OR 3.5, 95% CI 1.2-10.5). Comparing stapler groups, BAS was detected in 35 of 165 patients (21%) in the 28-29mm group but in only four out of 74 (5.6%) in the 31-33mm group (p = 0.002, 95% CI 7.27-23.53). Ileostomy closure took longer and was less frequent in the 28-29mm group. The rate of BAS after LAR was not negligible, since it was recorded in 39 of 239 patients (16.3%). The use of a 31-33mm CMS was associated with a lower incidence of BAS. Therefore, the use of larger staplers is tentatively recommended; however, clinical trials are now required to confirm these results.

Anastomotic leak rate following the implementation of a powered circular stapler in elective colorectal surgeries: a retrospective cohort study.

The objective of this study was to compare the anastomotic leak rates between powered and manual circular staplers in elective left-sided colorectal resections. A retrospective cohort study of elective left-sided colorectal resections before and after implementation of a powered circular stapler at a tertiary care center was conducted. The manual stapler group consisted of consecutive resections performed between January 2016 to December 2016 and the powered stapler group, between September 2021 and December 2022. Primary outcome was 30-day anastomotic leak rate. A chi-squared analysis was performed to compare anastomotic leak rates. Factors associated with anastomotic leak were examined. Two-hundred forty-seven patients were included: 154 in the manual stapler group and 93 in the powered stapler group. Mean (SD) age was 60 (15) years old, 37.7% were female and 72.9% of resections were performed for malignancy. Both groups had similar patient characteristics and surgical technique. Overall leak rate was 2.0% in the manual stapler group and 10.8% in the powered stapler group. The powered staplers were found to have 6.06 times the odds of leak compared to manual staplers (95% CI, 1.62-22.65; p = 0.01). None of the other factors were found to be associated with anastomotic leak. Patients who had left-sided colorectal anastomosis had higher anastomotic leak rates with powered compared to manual circular staplers. This finding is contrary to previous retrospective studies that found lower leak rates with powered staplers.

Optimizing treatment strategies for pediatric phimosis and redundant prepuce: a comparative study of traditional circumcision and disposable circumcision stapler.

To investigate the surgical outcomes and complication rates of traditional circumcision and disposable circumcision stapler in the treatment of pediatric patients with phimosis and redundant prepuce. A retrospective analysis was conducted on pediatric patients with phimosis or preputial redundancy treated at our pediatric surgery department from January 2022 to December 2023. The patients were divided into two groups: treated with traditional circumcision (control group) and treated with a disposable circumcision stapler (experimental group). Surgical parameters (operation time, intraoperative bleeding), postoperative outcomes (postoperative pain scores, wound healing time, severe edge swelling, wound dehiscence, postoperative rebleeding, postoperative infection, aesthetic satisfaction), were compared between the two groups. A total of 301 pediatric patients were included in our study, with 146 in the traditional group and 155 in the stapler group. The stapler group showed significantly lower values in operation time, intraoperative bleeding, and postoperative rebleeding compared to the traditional group (P < 0.05). However, the traditional group had a significant advantage in postoperative wound healing time and the occurrence of severe edge swelling (P < 0.05). There were no significant differences between the two groups in terms of anesthetic drug dosage, postoperative pain level, postoperative infection rate, wound dehiscence, and aesthetic satisfaction (P > 0.05). In the treatment of pediatric phimosis and redundant prepuce, the advantage of traditional circumcision lies in faster postoperative recovery and less severe edge swelling. The disposable circumcision stapler excels in thorough hemostasis, easy and safe operation, suitable for primary medical use, but lags behind in postoperative recovery compared to the traditional method. Each treatment approach has its own advantages, and the choice should be based on the actual condition and circumstances of the patient. Personalized treatment decisions should be made collaboratively to achieve the best therapeutic outcomes.

Comparison of the wound healing and complications of zipper type closure adhesive tape and stapler for surgical wound suture: A randomized control, single-centre, open-label trial.

Xkin closure is a newly developed medical suture device for lacerations and surgical wounds that can reduce scarring, pain and the risk of infection compared with conventional sutures or staplers. A randomized controlled study was performed to compare the wound healing effects and complications of Xkin closure with stapler closure. Fifty patients who underwent robot-assisted radical prostatectomy for prostate cancer were randomly assigned. Only the wound above the navel, which was extended to take out the prostate was targeted. The wound was examined at 2, 6 and 12 weeks after surgery, and the modified Vancouver Scar Scale (mVSS), scar height and side effects were assessed with a 3D skin analyser. Forty-six patients (23 Xkin, 23 Stapler) were analysed. The mVSS scores, vascularity and pliability were significantly lower in the Xkin group compared with the stapler group at the 12-week follow-up. No significant differences in the maximum peak and depth of the scars were detected between the two groups using 3D photographs at 12 weeks. Xkin is an effective wound closure method for improving scar outcomes. This method is expected to be widely used for surgical wounds and lacerations caused by trauma in daily life.

Systemic assessment of manual circular stapler versus powered circular stapler for anastomosis in rectal cancer: A multicenter prospective cohort study.

e15614 Background: Mechanical anastomosis offers several advantages over traditional hand-sutured anastomosis. However, complications such as anastomotic leaks, strictures, and bleeding persist due to factors like interactions between staples and tissue. Powered circular anastomosis is an effective method to address these issues. Currently, there are no domestic studies on the application of powered-anastomosis technology in colorectal anastomosis. Methods: The study adopted a multicenter, randomized, parallel-controlled, non-inferiority study design, with a 1:1 random allocation ratio. The study involved 187 patients with rectal cancer who underwent Dixon surgery using IntoCare™ disposable powered circular stapler (ICS), and 195 patients who received similar process with manual circular stapler (MCS). The efficacy of stapler was evaluated by anastomosis success rate, anastomosis-related adverse events, anastomosis device performance assessment, operation time, anastomosis time, and postoperative recovery. Safety evaluation indicators included adverse events, vital signs, and laboratory tests. Results: Baseline demographic characteristics showed no notable disparities between two groups (Table 1). A high proportion of patients, 99.47% in the MCS group and 99.49% in the ICS group, successfully completed anastomosis. In the MCS group, the average anastomosis duration was clocked at 2.84 minutes (min) (±2.3), with a median time of 2.0 min (ranging from 1.0 to 22.0 min). In contrast, the ICS group exhibited a slightly quicker average anastomosis duration of 2.40 min (±1.7), and a comparable median time of 2.0 min (but with a narrower range from 1.0 to 15.0 min). Adverse events did not differ significantly between two groups. Conclusions: The results uncovered the powered stapler could considerably reduce stapling time while maintaining a safety profile. Notably, the incidence of patients with anastomotic leakage one month post-surgery, and anastomotic stricture six months post-surgery in the powered stapler group, was lower than those in the manual stapler group. This suggests that the anastomosis created by the powered stapler is more stable and promotes more effective postoperative anastomotic healing. Clinical trial information: NCT05879172 .

A Comparative Study of Wound Infections Following Wound Closure Using Staples and Absorbable Sutures Among Obese Patients Undergoing Lumbar Fusion Surgery.

Background Infections of the wounds, organs, or spaces that develop following surgery are known as surgical site infections (SSIs). Theincidence of wound infections in obese patients undergoing lumbar spine surgery with the use of absorbable sutures versus staples for skin closurehas not been studied previously. Materials and methods We conducted a retrospective observational study in our hospital where cases of lumbar spine surgery meeting the inclusion criteria were chosen retrospectively from March 2021 to March 2023. A total of 40patients aged >18 years and <75 years who underwent lumbar spine surgery were covered by this investigation. Two cohorts with 20 patients in each were chosen from thepopulation. Group A used a skin stapler to close wounds, whereas group B used absorbable sutures. The number of wound infections was the main result. Using SPSS version 23.0 (IBM SPSS Statistics, Armonk, NY), all data were analyzed after being entered into an Excel sheet (MicrosoftCorp., Redmond, WA). Results A total of 40 participants were included in this study, and it revealed that there was no discernible variation in the groups' mean age or gender distribution. There is a significantly higher incidence of SSI in the absorbable suture group (35%) compared to the staplegroup (15%). The mean duration in days for the development of SSI in the absorbable suture group (9.86±2.12) was early compared to the staple group (12.67±2.08), which was statistically significant (p<0.05). Conclusion Compared to absorbable sutures, the current study showed a decreased incidence of surgical site infection in obese individuals receiving skin staples for wound closure.

THREAD OR STAPLE: A COMPARATIVE ANALYSIS OF SURGICAL TECHNIQUES IN CIRCUMCISION SURGERY

Introduction: Male circumcision was one of the earliest operations performed by humans.The circular stapler, is a new disposal circumcision device discovered in China. It is a novel technique showing quicker procedure time, lesser complication, and sutureless. Methods: A study was conducted on 50 Adult males undergoing circumcision surgery under local anesthesia in a tertiary hospital in Navi Mumbai. They were randomized into 2 groups. In Group A conventional suturing was done and in Group B with staplers. Time efficacy calculated by stopwatch(s). Post-operative complications along with cost-effectiveness between the two techniques. Cost-effectiveness between two techniques. Results: The operative time is quicker in group B compared to conventional suturing. The intraoperative and postoperative pain scores were significantly lower in the stapler group compared to conventional suturing. It is observed that in Stapler group had higher treatment costs than conventional suturing. In group B receiving stapler had fewer post-operative complications than the conventional group. Conclusion: The present study has demonstrated that the stapler circumcision technique is superior to the conventional suturing technique. The stapler technique is quicker and less complicated with good patient compliance. A drawback is a costly approach and training in manual skills that require a precise application. The study needs to be on a larger scale with a larger population for further improvement.

Accelerating Fleur-de-lis Panniculectomy with the Absorbable Dermal Stapler-A Study of Efficiency, Aesthetics, and Quality-of-life.

Fleur-de-lis panniculectomy (FDL), a contouring technique involving vertical and horizontal tissue resections, often involves longer operative times and potential complications. This study assessed operative time, postoperative outcomes, and patient-reported quality of life (PRO) with Insorb® Absorbable Subcuticular Skin Stapler versus traditional sutures during FDL. A retrospective review from 2015 to 2022 of FDL patients excluded those with complex concomitant procedures. Demographics, operative details, and surgical outcomes were compared between patients using the dermal stapler and those with suture-only closures. Forty subjects were identified, with 25 (62.5%) in the dermal stapler cohort. The dermal stapler significantly reduced total procedure time (66.76 vs. 125.33 min, p < 0.05). There were no significant differences in surgical site occurrences, aesthetic outcomes, readmissions, or reoperations. Multivariate regression analysis further highlighted the choice of closure technique as an independent predictor of operative time, with traditional sutures indicating a significantly increased operative time compared to using the dermal stapler (AOR 76.53, CI 38.11-114.95, p < 0.001). Regarding PROs, both groups saw improvements across multiple BODY-Q domains, but the dermal stapler group reported greater enhancements (six out of nine domains vs. three for sutures). The absorbable dermal stapler significantly reduces FDL operative time without increasing wound healing or aesthetic dissatisfaction incidents and maintains comparable quality-of-life improvements to standard suture closure.

Stapler versus conventional pharyngeal repair after total laryngectomy: a randomized clinical trial

ObjectivesThe aim of the current study was to evaluate the functional outcomes of stapler pharyngeal closure after total laryngectomy by the incidence of PCT and assessment of swallowing after surgery. In addition, the study aimed to evaluate the oncological outcomes in terms of patients’ survival rates.MethodsThis randomized clinical trial was conducted on 58 patients with advanced laryngeal carcinoma who underwent total laryngectomy. Patients were randomly assigned to two groups according to the method of pharyngeal repair after laryngectomy: manual closure group (n = 28), and stapler group (n = 30). Functional and oncological outcomes were assessed and compared.ResultsThe incidence of pharyngocutaneous fistula was significantly less in the stapler group. Additionally, operative time was significantly shorter and swallowing function was better in the stapler group compared to the manual group. There was no statistically significant difference between groups regarding survival rates.ConclusionThe stapler is a reliable method for pharyngeal closure after total laryngectomy if the limits of its indications regarding the primary tumor are considered. Stapler closure decreases the incidence of PCF and decreases the surgical time. Good swallowing outcomes are achieved without compromising the oncological outcomes.

Proximal ligation technique prevents thrombus formation in the pulmonary vein stump after lobectomy.

To assess the risk factors for thrombosis in the pulmonary vein stump (PVT) and the efficacy of proximal ligation in preventing PVT after lobectomy. In total, 649 surgical patients with lung cancer were retrospectively reviewed. To compare the clinical effectiveness of PV proximal ligation, the simple stapler group (290 patients) and the proximal ligation group (359 patients who underwent thread ligation at the pericardial reflection with/without a stapler) were analyzed. In the simple stapler group, 12 of 290 patients (4.1%) developed PVT. Among these, 9 of 58 underwent left upper lobectomy (LUL). In contrast, 5 of the 359 patients (1.4%) in the proximal ligation group developed PVT. All five patients received LUL. The incidence of PVT in the proximal ligation group was significantly lower than that in the simple stapler group (p = 0.0295) as well as in the analysis by LUL alone (p = 0.0263). A logistic regression analysis indicated that higher BMI and LUL were associated with the development of PVT (p = 0.0031, p < 0.0001), and PV proximal ligation reduced PVT (p = 0.0055). Proximal ligation of the PV has the potential to prevent PVT, especially after LUL.

Efficacy of pancreaticojejunostomy of the pancreatic stump during distal or central pancreatectomy.

A stapler is usually used for transection and closure of the pancreas in distal pancreatectomy (DP) or central pancreatectomy (CP). When the pancreas is transected to the right of the portal vein, it is difficult to use a stapler and clinically relevant postoperative pancreatic fistula (CR-POPF) frequently occurs. We report on the efficacy of pancreaticojejunostomy (PJ) of the pancreatic stump for patients in whom stapler use is difficult. Patients who underwent DP or CP were enrolled in this study. The pancreas was usually transected by a stapler, and ultrasonic coagulating shears (UCS) were used depending on the tumor situation. When using UCS, hand-sewn closure or PJ was performed for the pancreatic stump. The relationship between clinicopathological factors and the methods of pancreatic transection and closure were investigated. In total, 164 patients underwent DP or CP, and the pancreas was transected with a stapler in 150 patients and UCS in 14 patients. The rate of CR-POPF was higher and the postoperative hospital stay was longer in the UCS group than in the stapler group. PJ of the pancreatic stump, which was performed for 7 patients, did not worsen intraoperative factors. CR-POPF was not seen in these 7 patients, which was significantly less than that with hand-sewn closure. PJ of the pancreatic stump during DP or CP reduces CR-POPF compared with hand-sewn closure and may be useful especially when the pancreas is transected to the right of the portal vein.

Open distal pancreatectomy stump closure by linear stapling versus continuous suturing: a retrospective–prospective comparative study

Background Distal pancreatectomy (DP), performed for removing pancreatic lesions located to the left of the superior mesenteric vein, accounts for ~25% of all pancreatic resections. Most recently reported overall mortality rate of DP is less than 3%. However, albeit technically simpler to perform than pancreaticoduodenectomy, morbidity rate of DP remains substantial. Postoperative pancreatic fistulas (POPFs), which may result in numerous clinically significant and potentially life-threatening complications such as intraabdominal abscess, hemorrhage, and surgical site infection, is the leading cause of morbidity after DP, with an incidence of ~30–60%. Risk factors associated with POPFs after DP include decreased serum albumin levels, concurrent splenectomy, increased body weight, increased duration of surgery, higher American Society of Anesthesiologists score, and impaired renal function. Furthermore, POPFs often translate to significant increases in hospitalization costs. Objective To compare the technique of DP stump closure in two groups of patients; a group underwent stump closure with linear stapling technique and the other group underwent stump closure with continuous suturing technique. Patients and methods This was a retrospective–prospective clinical trial that was conducted at General Surgery Department, Ain Shams University Hospitals on 30 patients who were admitted to specialized hepatobiliary units in Cairo, Egypt for open DP. Between January 2020 and June 2022 with postoperative follow-up period of 2 months. In our study, there were 30 patients (15 in the continuous suturing technique group and 15 in the linear stapling technique group) with a mean age of 45.37±10.662 years. Groups were similar in demographic and clinical characteristics (P&gt;0.05). Results In our study, 13.33% patients in continuous suturing technique group developed clinically relevant POPF (grade B and grade C POPF), whereas 33.33% patients in stapling technique group develop POPF (P=1.00). The amount of the blood loss which was found to be statistically significant as the P value was found less than 0.05 and the t test was found to be −2.396 which mean that the amount of the blood lost was more in the stapler group. There was no statistically significant difference in the rate of clinically relevant POPF (grade B and grade C POPF) with suture closure compared with stapler closure (13.33 vs. 33.33%). There was no statistically significant difference in the risk of intraabdominal abscess. There were three (20%) patients with a biochemical leak in continuous suturing technique group. In stapling technique group, three (20%) patients developed biochemical leaks. There was no significant in difference between groups in terms of biochemical leak. In our study, mortality rates did not differ between stapler and suture closure techniques. Conclusion Our study showed no significant difference between suture and stapler closure of DP stump with respect to POPF or intraabdominal collection after DP. The amount of the blood lost was more in the stapler group.

Comparison of 2-octyl cyanoacrylate with polyester mesh with standard suture and staples in total knee and hip arthroplasty.

The use of 2-octyl cyanoacrylate with polyester mesh (OCA-M) has become common in total hip and knee arthroplasty (THA, TKA). We aimed to compare the safety and cosmetic outcomes between OCA-M and standard suture techniques and staples, and determine whether OCA-M can safely be used for TKA. Inclusion criteria were patients who underwent THA or TKA from January 2010 to October 2011 (Suture group), November 2011 to August 2013 (Staple group), March 2017 to September 2018 (OCA-M group). Exclusion criteria was loss of imaging data. Complications during hospitalisation (early complication) and after discharge (late complication) were compared in groups. Plastic and orthopaedic surgeons performed cosmetic evaluations with the modified Vancouver Scar Scale (VSS) and Likert scale at three and six months postoperatively and compared in groups. A total of 249 arthroplasties (suture group=88 patients; staple group=94 patients; OCA-M group=67 patients) were included in the study. The OCA-M group had a significantly lower early complication rate than the suture group (p=0.015). For THA, the OCA-M group had a significantly lower total complication rate than the suture group (p=0.048). For TKA, there was no significant difference among the three groups. The complication rate in the OCA-M group showed no significant difference between THA/TKA. With regards to the VSS, the OCA-M group was significantly better for cosmetic qualities than the suture group (p=<0.001, p=0.021 at three and six months, respectively). For the Likert scale, the OCA-M group was also significantly better for cosmetic qualities than the suture group and staple group (suture-OCA-M, p=0.003 (three months), p=<0.001 (six months); staple-OCA-M, p=0.027 (three months)). In this study, the OCA-M complication rate was low compared to suturing and similar to stapling. Moreover, better cosmetic outcomes were achieved compared to suturing and stapling.

Is circular-stapled gastrojejunostomy anastomosis apppropriate for pancreaticoduodenectomy?

INTRODUCTION:Pancreaticoduodenectomy is a highly complex procedure that requires surgical experience.. Among these is the use of a stapler in the construction of the gastrojejunostomy anastomosis during the procedure. Our study compares the patient outcomes of gastrojejunostomy anastomosis procedures performed manually and with a circular stapler. MATERIALS AND METHOD:Our study retrospectively evaluated the data of 44 patients who had undergone pancreaticoduodenectomy performed by the same surgical team between May 2015 and December 2019. The manual gastrojejunostomy anastomosis(n = 32) and stapled (circular stapler 25 millimeter) anastomosis(n=12) patient groups were compared for anastomotic stricture. RESULTS:Of the 44 patients undergoing pancreaticoduodenectomy, 68.2% were male, the mean age was 62.9±12.1 years and the mean follow-up was 28.2±21.2 months. The rate of gastrojejunostomy stricture was significantly higher in the circular stapler group (p = 0.017;p &amp;lt; 0.05). CONCLUSION:The increased risk of postoperative pancreatic fistula and anastomotic stricture prevents us from recommending the use of a circular-stapler in the creation of the gastrojejunostomy anastomosis in pancreaticoduodenectomy procedures, as it increases the risk of postoperative pancreatic fistula and anastomotic stricture, and provides no operative time advantage.

A COMPARATIVE ANALYSIS OF MEMORY STAPLES AND COMPRESSION PLATE WITH CROSS SCREW FOR FIRST METATARSOPHALANGEAL (MTP) JOINT ARTHRODESIS: A QUANTIFICATION OF FUNCTIONAL OUTCOMES UTILIZING THE MANCHESTER–OXFORD FOOT QUESTIONNAIRE (MOXFQ)

Arthrodesis of the first metatarsophalangeal joint (MTPJ) is the most reliable surgical option, for hallux rigidus from end-stage osteoarthritis. The aim of the study was to compare the functional outcomes of memory nickel-titanium staples versus a compression plate with a cross screw construct for first MTPJ arthrodesis using the Manchester–Oxford Foot Questionnaire (MOXFQ).Patients who underwent MTPJ arthrodesis using either memory nickel-titanium staples or a compression plate with a cross screw construct were identified from the surgical lists of two orthopaedic consultants. Pre and post-operative MOXFQ questionnaire, a validated patient-reported outcome measure, was administered, and responses were analysed to derive the MOXFQ summary index.The study included 38 patients (staple group N=12 and plate and cross screw group N=26). 23 patients were female and 15 were male. Mean age was 64.8 years (SD 9.02; 40 to 82). Initial analysis showed no significant difference in preoperative MOXFQ scores between the groups (p = 0.04). Postoperatively, the staple group exhibited a mean improvement of 36.17, surpassing the plate group's mean improvement of 23. Paired t-test analysis revealed a statistically significant difference (t-score= 2.5, p = 0.008), favouring the use of staples.The findings indicate that the use of staples in MTPJ arthrodesis resulted in a significantly greater improvement in MOXFQ scores compared to plates. Further research is needed to explore the underlying factors contributing to this difference and to evaluate long-term effects on patient outcomes.

Comparing stapler and sutured mesh fixation techniques for laparoscopic TAPP repair: a study on chronic groin pain on 3-year follow-up

Trans-abdominal preperitoneal (TAPP) and totally extraperitoneal (TEP) repairs are the available surgeries for inguinal hernias, with both methods of laparoscopic repairs requiring mesh applications. This study analyzes the correlation between sutured versus stapler mesh fixation in a laparoscopic TAPP for unilateral groin hernia regarding chronic pain during 3-year follow-up. A total of 130 patients with laparoscopic hernia undergoing TAPP repair were randomized into 2 groups based on their fixation technique—one with sutures and the other with stapler. Postoperative complications and chronic groin pain were noted for each technique. Equal number of participants was present in the stapler and suture groups, with the majority having an ASA score of one. The mean age was 42.50 ± 13.86 years, and the body mass index (BMI) was 27.47 ± 5.88. The stapler group presented a shorter mean operative time than the suture group. However, the stapler group had a significantly higher mean VAS score than the suture group. Most participants in the suture group (89.2%) had LOS for 1 day, while a 2-day LOS was significantly higher in the stapler group (12.3%) than in the suture group (9.2%). No patient reported mesh erosion, conversion, recurrence, testicular atrophy, and mesh infection. Early postoperative pain was more in stapler group along with long hospital stay, but both were non-significant. Chronic postoperative pain results and recurrence incidences over 3-year follow-up were also similar. Re-admission rates were minimal, no significant complications occurred.

Can a stapling device with bioabsorbable polyglycolic acid felt reduce intraoperative air leak?

Currently, it is unknown whether polyglycolic acid (PGA) felt staplers can reduce the occurrence of intraoperative air leaks. We investigated whether staplers with bioabsorbable PGA felt reduced intraoperative air leakage compared to the conventional stapler in patients undergoing lung resection. From 2013 to 2021, 211 patients diagnosed with lung cancer or pulmonary metastasis underwent lung resection using only PGA felt (n=88) or conventional (n=123) staplers at Tokyo Rosai Hospital. One-to-one propensity score matching was used to compare intraoperative air leak rates, operation time, and intraoperative bleeding between the two groups. The PGA felt group required more staples than the conventional stapler group. The forced expiratory volume in one second percentage of predicted in the PGA felt stapler group was lower than that in the conventional stapler group. In the PGA felt stapler group, 56.8% of patients had undergone anatomic lung resection, whereas 29.3% of patients in the conventional stapler group had undergone wedge resection. In a propensity-matched analysis of 67 pairs, the occurrence of intraoperative air leaks was significantly lower in the PGA felt stapler group than in the conventional stapler group (16.4% vs. 56.7%, P<0.001). The operation time was significantly shorter and intraoperative bleeding was significantly lower in the PGA felt stapler group than in the conventional stapler group (P=0.001 and P=0.016, respectively). Pulmonary resection using staplers with a PGA felt could reduce the occurrence of intraoperative air leaks among patients undergoing lung resection.

Is the risk of wound complications after total hip arthroplasty with suture closing the skin lower than closing the skin with staples?

AbstractThis is a study assessing the effectiveness of staples versus sutures for closing incisions after total hip arthroplasty (THA). We searched all relevant literature up to July 2023, and after reading through the full text, we finally included 5 for analysis, with a total of 1084 cases who underwent total hip arthroplasty, of which 548 were closed with staples and 536 with sutures, and evaluated the risk of bias with the Cochrane Risk of Bias Assessment Tool, using the ratio of ratios (OR) and 95% confidence intervals (CI) to compare the effectiveness of staples and sutures in wound closure in total hip arthroplasty. The study found that the suture group was superior to the staple group in terms of superficial infection and incisional exudate; superficial infection (OR = 3.04, 95% CI: 1.14–8.07; p = 0.03, I2 = 0%), incisional exudate (OR = 3.22, 95% CI: 1.84–5.65; p &lt; 0.001, I2 = 0%) and suture staples were superior to suture group in terms of closure time (WMD = −231.8 95% CI: −429.55 to −34.05; p = 0.02, I2 = 100%). There was no remarkable distinction between the two groups in terms of deep infection, postoperative hospital, HWES score and patient's satisfaction, deep infection (OR = 1.24, 95% CI: 0.35–4.35; p = 0.74, I2 = 0%), postoperative hospital (WMD = 2.50 95% CI: −2.25 to 7.25; p = 0.30, I2 = 100%), HWES score (WMD = −0.38 95% CI: −0.52 to −0.24; p &lt; 0.01, I2 = 72%) and patient's satisfaction (WMD = −0.23 95% CI: −1.43 to 0.96; p = 0.70, I2 = 94%); however, due to the small sample sizes of several studies included in this study, caution must be exercised when addressing their value.

Comparison of Skin Staples versus Skin Sutures After Inguinal Hernioplasty in Terms of Surgical Site Infection

Background: Surgical site infection is a major concern following inguinal hernia repair, potentially leading to extended hospital stays, increased morbidity, patient discomfort, and higher healthcare costs. This study aimed to conduct a comparative analysis between skin staples and skin sutures in inguinal hernioplasty, explicitly focusing on their impact on surgical site infection rates. Methods: From September 2022 to June 2023, a randomized control trial study was carried out at the Surgery Department, Kulsoom Bai Valika Hospital Karachi. A total of 100 patients who underwent Lichtenstein tension-free mesh hernioplasty were allocated into two groups: the stapler group (n=50) and the polypropylene suture group (n=50). The patients were monitored for 3 to 6 hours post-surgery and safely discharged on the first postoperative day. Follow-up was scheduled 7 days after surgery to assess wound complications, specifically surgical site infections. Comparison between both groups was done using the Chi-square/Fisher exact test for surgical site infection and independent samples t-test for pain score. The level of significance was set at 5%. Results: The incidence of postoperative pain was slightly lower in the stapler group compared to the suture group (10% vs. 16%), this difference was not statistically significant (p=0.544). Moreover, the surgical site infection rate was significantly lower in the stapler group (3%) than in the suture group (12%) with p=0.012. Conclusion: When securing the mesh in inguinal hernia cases, the utilization of skin staples was considered a safe approach and was associated with lower surgical site infection as compared to skin sutures.
