Postoperative risk of bleeding after removal of third molars in healthy patients - a prospective observational clinical study

Removal of third molars in healthy patients is considered a procedure with a low risk of bleeding. However, exactly how low the incidence of postoperative bleeding is remains unclear due to the heterogeneity of available studies. To determine the exact postoperative risk of bleeding after the removal of third molars in healthy patients, a prospective observational multicentre study was conducted. A total of 1,035 patients with complete follow-up was included. Of these, 329 patients reported subsequent bleeding, but did not consult their attending physician. A total of 15 patients visited the hospital, 8 of whom required minimally invasive (re)treatment. No hospitalizations were necessary. There was a large difference between the incidence of postoperative bleeding reported by patients and postoperative bleeding requiring clinical examination and/or treatment. To reduce this difference in future, patients should be given detailed information about what degree of postoperative bleeding is considered normal after removal of a third molar.

The Influence of Preoperative Anticoagulant and Antiplatelet Therapy on Rebleeding Rates in Patients Suffering from Spinal Metastatic Cancer: A Retrospective Cohort Study.

The age of patients requiring surgery for spinal metastasis, primarily those over 65, has risen due to improved cancer treatments. Surgical intervention targets acute neurological deficits and instability. Anticoagulants are increasingly used, especially in the elderly, but pose challenges in managing bleeding complications. The study examines the correlation between preoperative anticoagulant/antiplatelet use and bleeding risks in spinal metastasis surgery, which is crucial for optimizing patient outcomes. In a retrospective study at our department from 2010 to 2023, spinal tumor surgery patients were analyzed. Data included demographics, neurological status, surgical procedure, preoperative anticoagulant/antiplatelet use, intra-/postoperative coagulation management, and the incidence of rebleeding. Coagulation management involved blood loss assessment, coagulation factor administration, and fluid balance monitoring post-surgery. Lab parameters were documented at admission, preop, postop, and discharge. A cohort of 290 patients underwent surgical treatment for spinal metastases, predominantly males (63.8%, n = 185) with a median age of 65 years. Preoperatively, 24.1% (n = 70) were on oral anticoagulants or antiplatelet therapy. Within 30 days, a rebleeding rate of 4.5% (n = 9) occurred, unrelated to preoperative anticoagulation status (p > 0.05). A correlation was found between preoperative neurologic deficits (p = 0.004) and rebleeding risk and the number of levels treated surgically, with fewer levels associated with a higher incidence of postoperative bleeding (p < 0.01). Surgical intervention for spinal metastatic cancer appears to be safe regardless of the patient's preoperative anticoagulation status. However, it remains imperative to customize preoperative planning and preparation for each patient, emphasizing meticulous risk-benefit analysis and optimizing perioperative care.

Effect of Intraoperative Blood Pressure Regulation on Postoperative Hemorrhage After Bariatric Surgery

IntroductionWith a rising number of bariatric procedures, the absolute number of postoperative complications is increasing, too. Postoperative bleeding, particularly along the staple line, is a recognized challenge. Numerous strategies including reinforcement of the staple line (SLR) have been proposed to improve bleeding rates, but no single technique has shown superiority over the others. In our bariatric center, we have implemented intraoperative blood pressure regulation alone, without SLR, to reduce hemorrhagic complications postoperatively.MethodsThis retrospective observational analysis compares the incidence of postoperative bleeding in two groups of consecutive patients (total n = 438 patients), one with and one without intraoperative blood pressure elevation to 150 mmHg systolic without the additional use of staple line reinforcement. This intervention was integrated into our standard bariatric surgical procedure, no randomization or matching was conducted. Significant postoperative bleeding was defined as drop of hemoglobin of more than 2.5 mg/dl in 48 h and one of the following symptoms: lactate ≥ 2 mmol/L, bloody drainage, quantity of drainage more than 200 ml and/or radiological signs.ResultsDefined postoperative bleeding occurred in 33 (7.5%) patients. We observed a decrease in bleeding rates from 10% to 5% (n = 22 vs. n = 11) after introducing intraoperative blood pressure increase (p = 0.034). The rate of revisional surgery for bleeding also decreased from 2.7% to 0.5% (n = 6 vs. n = 1). In multivariate analysis, the intervention with blood pressure elevation showed a significant decrease on bleeding rates (p = 0.038).ConclusionThe use of increased intraoperative blood pressure alone, without staple line reinforcement, appears to be an effective and suitable method for reducing post-bariatric hemorrhagic complications.Graphical

How good are we really? Incidence of postoperative bleeding requiring intervention and intraoperative electrocoagulation during Thulium laser enucleation of the prostate

The need for intervention due to postoperative bleeding represents a significant complication in Thulium Laser Enucleation of the Prostate (ThuLEP). This study aimed to retrospectively analyse this complication in the treatment of benign prostatic enlargement. This study focuses on investigating potential causative factors for postoperative bleeding requiring intervention as well as the use of intraoperative electrocoagulation. A total of 503 ThuLEP procedures performed between 08/2021 and 07/2022 were examined. Postoperatively, 4.2% (n=21) of patients experienced bleeding requiring intervention. Study data revealed a significant association between these instances of bleeding and a high prostate volume (p=0.004), high enucleation weight (p=0.004), and intraoperative electrocoagulation (p=0.048). In total, intraoperative electrocoagulation was applied in 41.2% (n=207) of cases. In these cases, statistically significant factors leading to the application of electrocoagulation included intraoperative capsule perforation (p=0.005) and high enucleation weight (p=0.002).

Does resident involvement in tonsillectomy affect outcomes?

ObjectiveTonsillectomy is essentially a solo surgery with a well-described complication profile. It may serve as a good benchmark to evaluate the resident-as-surgeon. This study examined complications such as post-tonsillectomy bleeding in children undergoing tonsillectomy by attending surgeons (AS) or pediatric otolaryngologist-supervised residents. MethodsCharts were reviewed of all children aged 12 and under who had tonsillectomy +/− adenoidectomy at a children's hospital between Jan 2019 and Dec 2020. Patient age, gender, BMI, indication for surgery, surgical technique, presence of a resident surgeon, primary bleeding, secondary bleeding, treatment of bleeding, other Emergency Room (ER) visits, and clinic phone calls were recorded. Binary logistic regression was performed. Results2051 total children (1092 (53.2 %) males and 956 (46.6 %) females) with a mean age of 6.1 years (95 % CI 6.0–6.2) were included. 1910 (93.0 %) underwent surgery for tonsillar obstruction. 1557 (75.9 %) underwent monopolar cautery tonsillectomy. 661 (32.2 %) had a resident surgeon. 274 (13.4 %) had a related ER visit within 15 days. 18 (0.9 %) had a primary bleed and 155 (7.6 %) had a secondary bleed. Binary logistic regression showed that significant predictors of postoperative ER visits were patient age (OR = 1.101, 95 % CI = 1.050–1.154, p < .001) and resident involvement (OR = 0.585, 95 % CI = 0.429-,797, p < .001). Only age was associated with overall postoperative bleeding incidence (OR = 1.131, 95 % CI = 1.068–1.197, p < .001), as well as secondary bleeding (OR = 1.128, 95 % CI = 1.063–1.197, p < .001). There were no significant predictors of primary bleeding. ConclusionResident involvement in pediatric tonsillectomy is associated with decreased postoperative ER utilization and does not appear to increase common postoperative complications including bleeding and dehydration.

A Prospective Observational Study on Gastric Endoscopic Submucosal Dissection under Continuous Administration of Antithrombotic Agents.

Background: This study aimed to assess the completion rate and postoperative bleeding incidence of endoscopic submucosal dissection (ESD) for gastric tumors under continuous antithrombotic therapy. Methods: A prospective observational study was conducted including 88 patients with 100 gastric lesions who underwent gastric endoscopic submucosal dissection (ESD) and received continuous antithrombotic therapy. Additionally, retrospective data on gastric ESD in 479 patients with 534 lesions who did not receive antithrombotic therapy were collected for comparison. Results: The en bloc resection rates (100% in the continuous antithrombotic therapy group vs. 100% in the non-antithrombotic therapy group) and complete resection rates (97.0% vs. 96.3%, respectively) were high and comparable between the groups. No significant differences were found in the specimen size or procedure time. Perforation rates were low (0% vs. 2.3%, respectively) and were not significantly different between the groups. However, postoperative bleeding occurred significantly more frequently in the continuous antithrombotic therapy group (10.2% vs. 4.2%, respectively) than in the non-antithrombotic therapy group. The subgroup analysis revealed a higher incidence of postoperative bleeding in patients receiving thienopyridine derivatives. Conclusions: Continuous administration of antithrombotic agents, especially thienopyridines, increased the risk of postprocedural hemorrhage following gastric ESD. These findings support the need for careful consideration of pharamcological management before ESD, aligning with the current guidelines.

Laparoscopic liver resection is superior to radiofrequency ablation for small hepatocellular carcinoma: a systematic review and meta-analysis of propensity score-matched studies.

The approach in small hepatocellular carcinoma (HCC) is controversial, no prospective randomized trials to compare ablative or surgical approaches. We compared the surgical and oncological outcomes after laparoscopic hepatectomy (LH) and radiofrequency ablation (RFA) in small HCC patients based on matched cohort studies that performed propensity score matching (PSM). We systemically searched the PubMed, Cochrane Library, Embase, Web of Science, and the Chinese BioMedical Literature (CBM) databases. All published propensity score-matched studies that compared LH and RFA for small HCC were included in this study. Eight studies with a total of 1273 small HCC cases were included. The results of the meta-analysis revealed that there was no significant difference in the 1- year overall survival (OS) rate between the two groups, whereas the LH group had significantly higher 3- year overall survival rate (RR = 1.14, 95% CI 1.08-1.20, p < 0.00001) as well as 1- and 3-year disease-free survival (DFS) rates (RR = 1.31, 95% CI 1.22-1.42, p < 0.00001; RR = 1.66, 95% CI 1.46-1.90, p < 0.00001) than the RFA group. Meanwhile, the local recurrence rate and intrahepatic distant recurrence rate were significantly lower in the LH group than in the RFA group (RR = 0.29, 95% CI 0.20-0.42, p < 0.00001; RR = 0.67, 95% CI 0.49-0.92, p = 0.01). In comparison with the LH group, the RFA group had a lower incidence of overall and major postoperative complications (RR = 1.81, 95% CI 1.47-2.24, p < 0.00001; RR = 2.76, 95% CI 1.48-5.12, p = 0.001), but there was no significant difference in postoperative mortality between the two groups. In addition, further comparison of single postoperative complications showed that the incidence of ascites was lower in the RFA group than in the LH group (RR = 3.62, 95% CI 1.64-7.96, p = 0.001), whereas there was no significant difference in the incidence of postoperative bleeding, abdominal infection and bile leakage between the two groups (RR = 3.50, 95% CI 0.74-16.61, p = 0.11; RR = 5.00, 95% CI 0.59-42.23, p = 0.14; RR = 4.00, 95% CI 0.45-35.23, p = 0.21). Besides, the hospital stay was shorter in the RFA group than in the LH group (MD = 4.29, 95% CI 2.06-6.53, p = 0.0002). Our meta-analysis demonstrated that in comparison with RFA in the treatment of small HCC, LH provided superior long-term OS and DFS together with lower rates of local and intrahepatic distant recurrence after surgery. However, RFA was associated with better short-term outcomes.

Improved Patient Outcomes with Electrocauterization Following Wedge Resection and Curettage for Ingrown Toenails: A Prospective Comparative Study.

Background Ingrown toenail is a common condition that results in chronic pain, recurrent infections, and difficulty in performing daily activities. Our aim is to compare two surgical methods for the treatment of ingrown toenails: wedge resection with curetting versus wedge resection curetting followed by electrocauterization of the nail bed. Methods A prospective, comparative study that included 130 patients with ingrown toenails. All patients had stage II or III disease. We divided the participants into two groups according to the type of surgery and all patients were followed up for 6 months. The outcomes measured were the incidence of postoperative bleeding and infection, recovery time, patient satisfaction, and recurrence rate 6 months after surgery. Results Of the 130 patients included, 59 (45.4%) underwent excision and curetting of the nail matrix (group 1) and 71 (54.6%) underwent excision, curetting, and electrocauterization of the nail matrix (group 2). The postoperative infection rates were 20.3 and 4.2% in the first and second groups, respectively ( p = 0.004). Patient satisfaction was 76.3% among the first group, while 91.5% of patients in the second group were satisfied with the results of surgery. Six months postoperatively, recurrence rates were 25.4 and 4.2% in the first and second groups, respectively ( p = 0.001). Conclusion Wedge excision and curettage, followed by electrocauterization of the ingrown toenail is a safe treatment modality with a high success rate, that is evident by a lower recurrence rate, and greater patient satisfaction, with no effect on postoperative pain score or recovery time.

A Study of Association Between Initiating Time of Oral Feeding and Development of Postoperative Complications After Tonsillectomy &amp; Adenoidectomy Operation In Children

Background and Objectives Tonsillectomy is one of the most common operative procedures performed in children by otolaryngologists. However, many surgeons demand excessive fasting from their patients for the fear of pulmonary aspiration and postoperative bleeding after surgery. This study was performed to investigate the effect of early feeding after tonsillectomy on acute postoperative pain, vomiting and postoperative bleeding in children.Subjects and Method Data were collected via retrospective medical chart review. A total of 121 patients under the age of 12, who underwent tonsillectomy along with adenoidectomy in our hospital, were included in this study. The patients were divided into two groups according to the time of first water or liquid intake and first diet, respectively. Operation time, anesthesia time, state of appetite at the beginning of a soft diet, degree of postoperative pain, the requirement of intravenous analgesics and incidence of vomiting during hospitalization and incidence of postoperative bleeding were compared.Results There was no significant difference in the degree of pain, the requirement of intravenous analgesics, the incidence of vomiting or postoperative bleeding according to the time of first water or liquid intake. In addition, there was no difference in the degree of appetite and pain, the requirement of intravenous analgesics, incidence of vomiting or postoperative bleeding according to the time of first diet.Conclusion Initiating feeding as early as possible after tonsillectomy does not appear to increase acute postoperative pain, vomiting or postoperative bleeding.

Intra-operative Tranexamic Acid Administration Significantly Decreases Incidence of Postoperative Bleeding Without Increasing Venous Thromboembolism Risk After Laparoscopic Sleeve Gastrectomy: a Retrospective Cohort Study of Over 400 Patients.

There is evidence that tranexamic acid (TXA) reduces surgical bleeding and is widely used in trauma, obstetrics and other specialties. This practice is less well-established in laparoscopic sleeve gastrectomy (LSG) due to concerns surrounding venous thromboembolism (VTE); equally postoperative bleeding is a serious complication often requiring re-operation. This retrospective cohort study compared 30-day outcomes following primary LSG in patients receiving intra-operative TXA (March 2020-July 2022) to those who did not (March 2011-March 2020). The primary outcome was postoperative bleeding (Hb < 9g/dL) requiring transfusion or re-operation. Secondary outcomes were incidence of VTE, serious postoperative complications (Clavien-Dindo > grade 3) and death. Patients underwent standardised-protocol LSG without staple line re-enforcement under a single surgeon within the independent sector (private practice). TXA 1g intravenous was administered immediately after a methylene blue leak test, prior to extubation. TXA group had 226 patients and non-TXA group had 192 patients. Mean age was 40.5 ± 10.3 and 39.1 ± 9.8years, respectively. In the TXA group, no postoperative bleeds [versus 3 (1.6%) in non-TXA group, p = 0.0279] occurred. One staple line leak (0.4%) occurred in the TXA group compared to zero in the non-TXA group (p = ns). There was no VTE or death. This is the largest cohort study of intra-operative TXA in primary LSG to date, which demonstrates significant decrease in postoperative bleeding without increasing VTE risk. The authors recommend administration of TXA immediately following leak test, or removal of bougie to maximise efficacy. Data of TXA in LSG is awaited from the randomised controlled PATAS trial.

Clinical application of the dissection of the preperitoneal space without electrocoagulation in laparoscopic transperitoneal inguinal hernia repair throughout of the whole process.

The dissection of the preperitoneal space is performed using a monopolar instrument to prevent bleeding in laparoscopic transabdominal preperitoneal hernia repair (TAPP). It may also cause energy injuries and nerve damage. To assess the effectiveness and safety of dissection of the preperitoneal space without electrocoagulation (DPSWE) in TAPP throughout the process. A retrospective analysis of data of 134 patients was made. The electrocoagulation group (EG) relied on monopolar instruments. In the non-electrocoagulation group (NEG) mainly scissors were used without electrocoagulation. The patients were followed for up for 3 months. Intraoperative and postoperative conditions and other complications were observed. The VAS scores in the NEG were lower than those in the EG (p < 0.05). The operation time in the NEG was shorter than that in the EG (p < 0.05). Hospitalization expenses, scrotal seroma formation, and rupture of hernia sac in the NEG were lower than those in the EG (p < 0.05). The intraoperative bleeding volume above 20 ml in the NEG was higher than that in the EG. There was no significant difference in the incidence of postoperative bleeding, vas deferens injury, intestinal injury, surgical site infection, length of hospital stay, urinary retention and hernia recurrence in the NEG and the EG (p > 0.05). There was no significant difference in the incidence of surgical site infections (SSIs) in the NEG and the EG. DPSWE is effective and safe. DPSWE may reduce postoperative pain and have no significant increase in postoperative bleeding.

An initial experience with laser hemorrhoidoplasty in patients with grade 2-3 hemorrhoids

Hemorrhoids are detected in 11% of the adult population, and they account for 42% of all rectal disorders. According to leading coloproctology centres, about 30% of patients with chronic hemorrhoids require surgical intervention. Each of these methods has its own advantages and disadvantages. None of them, however, provides minimally invasive intervention, which is the prevailing trend in modern surgery. Objective — to conduct a comparative analysis and evaluate the outcomes of laser hemorrhoidoplasty and Milligan‑Morgan hemorrhoidectomy for patients with grade 2—3 chronic hemorrhoids. Materials and methods. The study presents the treatment outcomes of 59 patients with grade 2—3 chronic internal hemorrhoids. The main group included 29 patients who underwent laser hemorrhoidoplasty. As a surgical treatment, the 30 patients in the control group underwent the Milligan‑Morgan operation using an Ethicon Harmonic ultrasonic electrosurgical coagulator. Results. Treatment of hemorrhoids with a diode laser performed by a trained surgeon in accordance with the protocol and manner of execution offers a number of advantages compared to the traditional Milligan‑Morgan procedure. These advantages include a shorter operation time (p &lt;0.001), reduced intensity and duration of postoperative pain after laser hemorrhoidoplasty (an average of 3.59±1.15 days), whereas after Milligan‑Morgan surgery, it was 5.60±1.22 days (p &lt;0.001), decreased incidence of postoperative bleeding, and maintaining the radicality of the removal of the cavernous tissue substrate. Conclusions. In the surgical treatment of grade 2—3 chronic internal hemorrhoids, laser hemorrhoidoplasty of internal hemorrhoidal nodes has undeniable advantages over the standard Milligan‑Morgan procedure.

Epidemiology of postoperative bleeding after endoscopic nasal and sinus surgery and factors associated with bleeding

PurposeEndoscopic nasal and sinus surgery is a surgical procedure frequently performed by otolaryngologists. Postoperative bleeding is detrimental to both healthcare providers and patients. We investigated the epidemiology of postoperative bleeding during endoscopic nasal and sinus surgery and explored possible bleeding triggers.MethodsWe evaluated the patients who underwent endoscopic nasal and sinus surgery. Data regarding the age, sex, presence of hypertension, and abnormal coagulability, including oral anticoagulants, diagnoses, operative procedures, intraoperative use of drills and blood loss, and postoperative antimicrobial administration of eligible patients, were extracted from medical records and retrospectively reviewed.ResultsOne hundred and eighty-six patients underwent endoscopic nasal or sinus surgery during the study period, and postoperative bleeding occurred in 9 patients (4.8%). Posterior nasal neurotomy (PNN) was the procedure most likely to cause postoperative bleeding (4 surgeries, 13.3%). Postoperative antimicrobial administration significantly reduced the incidence of postoperative bleeding (p = 0.04).ConclusionsPostoperative bleeding requiring intervention occurs in 4.8% of cases, and PNN is associated with a high risk of postoperative bleeding. Wound infection is a potential cause of postoperative bleeding, and antimicrobial administration should be considered in addition to local treatment.

Postoperative Morbidity of Different Tonsillectomy Techniques: A Systematic Review and Network Meta-Analysis.

To compare different tonsillectomy techniques in terms of postoperative bleeding incidence and postoperative pain. An arm-based network analysis was conducted using a Bayesian hierarchical model. The primary and secondary outcomes were postoperative bleeding incidence and mean postoperative pain score. A total of 6464 patients were included for five different interventions (cold dissection tonsillectomy; extracapsular coblation tonsillectomy; intracapsular coblation tonsillectomy [ICT]; bipolar diathermy tonsillectomy [BDT]; monopolar diathermy tonsillectomy). ICT showed the lowest absolute risk (4.44%) of postoperative bleeding incidence (73.31% chance of ranking first) and the lowest mean postoperative pain score (1.74 ± 0.68) with a 94.0% chance of ranking first, whereas BDT showed both the highest absolute risk of bleeding incidence (10.75%) and the highest mean postoperative pain score (5.67 ± 1.43). ICT seems to offer better postoperative outcomes, in terms of reduced risk of bleeding and reduced pain. Further prospective studies are advised to confirm these findings.

Milligan-Morgan hemorrhoidectomy combined with non-doppler hemorrhoidal artery ligation for the treatment of grade III/IV hemorrhoids: a single centre retrospective study

BackgroundMilligan-Morgan hemorrhoidectomy (MMH) is the most widely used surgical procedure because of its precise curative effect, but it has the disadvantages such as obvious postoperative pain and bleeding. To retrospectively evaluate the efficacy and safety of MMH combined with non-Doppler hemorrhoidal artery ligation (MMH + ND-HAL) for the treatment of grade III/IV hemorrhoids.MethodsWe conducted a retrospective analysis of 115 patients with grade III/IV hemorrhoids, 53 patients had received MMH + ND-HAL, and the remaining 62 patients received MMH. We collected and compared demographic and clinical characteristics of both groups, including intraoperative blood loss, postoperative visual analog scale (VAS) for pain, analgesic consumption, postoperative bleeding, perianal incision edema, urinary retention, anal stenosis, anal incontinence incidence, recurrence rate (prolapse or bleeding), and patient satisfaction.ResultsThe VAS pain score of the first postoperative defecation and at the postoperative 12 h, 1 day, 2 days, 3 days, and 7 days, as well as the total analgesic consumption within 7 days, for the MMH + ND-HAL group were lower than those for the MMH group (P < 0.05). The intraoperative blood loss, the incidence of postoperative bleeding, perianal incision edema, and urinary retention in the MMH + ND-HAL group was lower than that in the MMH group (P < 0.05). No anal stenosis or anal incontinence occurred in either group. At follow-up by telephone or outpatient 12 months after surgery, the recurrence rate (prolapse or bleeding) was lower in the MMH + ND-HAL group than in the MMH group (P < 0.05), and satisfaction was higher in the MMH + ND-HAL group than in the MMH group (P < 0.05).ConclusionsMMH + ND-HAL was a satisfactory surgical modality for treating III/IV hemorrhoids.

Outcomes of (chinese) mini-percutaneous nephrolithotomy for renal stones: a prospective trial

Objective: Mini-percutaneous nephrolithotomy (mini-PCNL) has been recently advocated as a minimally invasive procedure for the management of renal stone. In this trial, we assessed the postoperative outcomes of chinese mini-PCNL (MPCNL) in adult patients with renal calculi less than 3 cm in diameter. Material and methods: We performed a single-arm prospective trial that recruited adult patients with unilateral single kidney stones less than 3 cm. Patients were followed up for the assessment of postoperative complications and stone-free status. Results: Sixty patients were included in the present study, with a mean age of 36.9 ±8.5 years and slightly male predominance (56.7%). The mean operative time was 133.7 ±29.2 minutes. None of the patients needed a nephrostomy tube or DJ tube stent. The mean hospital stay was 1.4±0.62 days. Eight patients (13.3%) showed mild perinepheric collection on the postoperative US. All patients had mild postoperative pain, with no incidence of post-operative bleeding, residual stone, sepsis, or pelvi-calyceal injury. A total of four patients (6.7%) had a postoperative fever. The incidence of postoperative urine was 13.3%. Conclusion: Chinese Mini-PCNL is an effective minimally invasive modality for the management of renal calculi less than 3 cm, with a low rate of postoperative complications and excellent stone-free status. Mini-PCNL can be used in well-resourced centres to reduce postoperative complications and hospital stay among patients with renal calculi.

Safety of Concomitant Laparoscopic Cholecystectomy and Laparoscopic Sleeve Gastrectomy in Morbidly Obese Patients: A Meta-Analysis

Abstract Background Laparoscopic sleeve gastrectomy is one of the most common bariatric procedure performed. The prevalence of cholelithiasis in morbidly obese individuals is 19–30 % and Gall stones are more symptomatic in obese patients than in non-obese patients. This study evaluates the safety of performing laparoscopic sleeve gastrectomy and laparoscopic cholecystectomy in the same session. Objective To evaluate the safety profile of performing laparoscopic cholecystectomy and sleeve gastrectomyin the same session in terms of : The incidence of biliary leakage. The incidence of gastric leakage. The incidence of intra operative bleeding from the sleeve gastrectomy and the cholecystectomy. The incidence of post-operative bleeding. The incidence of post-operative surgical site infection. Operation time. Length of hospital stay. Method Selected papers for the present meta-analysis included those that provided data from January 2010 to December 2020 on factors related to the patients who undergone laparoscopic sleeve gastrectomy with and without laparoscopic cholecystectomy. When institutions have published duplicate trials, only the most updated reports were included for qualitative appraisal. All publications were limited to human subjects and English language. Abstracts, case reports, conference presentations, editorials and expert opinions were excluded. Data Sources Medline databases (PubMed, Medscape, ScienceDirect. EMF-Portal) and all materials available in the Internet till 2021. Data Extraction If the studies did not fulfill the inclusion criteria, they were excluded. Study quality assessment included whether ethical approval was gained, eligibility criteria specified, appropriate controls, and adequate information and defined assessment measures. Conclusion Overall concomitant laparoscopic sleeve gastrectomy and laparoscopic cholecystectomy appears to be a safe procedure. The increase in surgical site infection and pneumonia may warrant prophylaxis against such infections with antibiotics. Another study is needed to determine the need and efficacy of such prophylaxis

Outcomes of Staple Line Reinforcement Following Robotic Assisted Sleeve Gastrectomy Based on MBSAQIP Database.

The objective of this study is to evaluate the outcomes for Staple Line Reinforcement (SLR) in RA-SG based on the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database for 2019. We selected patients who underwent RA-SG in the MBSAQIP PUF (Public Utility File) for the year 2019 and grouped them based on their SLR status: Oversewing (OS), Buttressing (BR), both OS and BR and neither. Our primary outcomes were bleeding, organ space infection (OSI), and adverse events (AEs), and our secondary outcomes were operation length, hospital length of stay, readmissions, and conversion to open rates. We conducted separate chi square or one-way analysis of variance (ANOVA) as appropriate and multivariable direct logistic regression models for the categorical outcomes. We found 115,621 patients with complete data of which there were 16,494 who underwent RA-SG. Our results did not show a statistically significant decrease in incidence of postoperative bleeding for BR and OS (Adjusted OR = 0.782, p = 0.2291 and Adjusted OR of 0.482, p = 0.054 for BR and OS respectively). There was a statistically significant effect for SLR status on operation length, with OS patients having the highest operative times (log-transformed mean = 2.03), followed by both BR + OS patients (log-transformed mean = 1.99). BR patients had the shortest operation length. SLR did not result in any significant differences related to bleeding, OSI or AEs following RA-SG according to MBSAQIP for the year 2019. However, OS resulted in significantly longer operative time compared to BR alone.

Comparison of Various Regimens of Antithrombotic Therapy in Patients With Valvular Heart Disease and Coronary Artery Disease After Surgical and Interventional Interventions

To evaluate the postoperative incidence of bleeding, incidence of thromboembolic complications, and all-cause mortality in patients with valvular heart disease and ischemic heart disease (IHD) associated with various regimens of the antithrombotic treatment during one year after surgery. This study included 271 patients with valvular heart disease and IHD after heart valve replacement and myocardial revascularization from 2009 through 2018. However, during the follow-up period (12 months), contact with 12 patients was lost, and therefore these patients were excluded from the study. Further analysis included 259 patients. Coronary artery bypass grafting (CABG) in combination with heart valve intervention was performed in 217 (83.8 %) patients, and percutaneous coronary interventions (PCIs) were performed in 42 (16.2 %) patients. There were 197 (72.7 %) male participants; median age was 64.0 [58.0; 67.5] years. The patients were divided into two groups. Group 1 consisted of 113 patients who received postoperative dual antithrombotic therapy (DAT) with acetylsalicylic acid (ASA)/clopidogrel+vitamin K antagonist (VKA). Group 2 included 146 patients receiving postoperative triple antithrombotic therapy (TAT) with ASA+clopidogrel+VKA. Follow-up duration was 12 months after surgery. Due to significant intergroup differences in major clinical anamnestic data, the data were adjusted using pseudo-randomization (Propensity Score Matching, PSM). In result, 109 patients were selected for each group. The incidence of adverse hemorrhagic outcomes was significantly higher in the group treated with TAT than with DAT. Minor bleedings were observed in 19 (17.4 %) vs. 8 (7.3 %) cases; moderate, clinically significant bleedings in 16 (14.7 %) vs. 6 (5.5 %) cases; and the total number of bleedings was 35 (32.1 %) vs. 14 (12.8 %; p=0.02, p=0.02, and р=0.001, respectively). Comparing the incidence of major bleedings did not show and significant intergroup differences (p=1.000). The incidence rate of any bleeding during the follow-up period was 32.1 % in patients treated with TAT (n=109) and 12.8 % in patients treated with DAT (n=109; p=0.005). The incidence of no bleeding during one year after surgery was 87 % in the DAT treatment group and 67 % in the TAT treatment group (p=0.005). The incidence of secondary endpoints, including ischemic stroke, myocardial infarction, prosthetic valve thrombosis, and death, was statistically non-significant. Administration of DAT vs. TAT after heart valve replacement and myocardial revascularization significantly decreases the incidence of any bleedings in the absence of significant differences in the incidence of thromboembolic events and mortality.
