A retrospective study of 3D laparoscopy and 2D laparoscopy in transabdominal preperitoneal (TAPP) for unilateral inguinal hernia in elderly patients

This study aims to explore the safety and efficacy of 3D laparoscopy in elderly patients undergoing transabdominal preperitoneal (TAPP) surgery for inguinal hernia. Patients were divided into two groups based on the laparoscopic equipment used during surgery. Clinical data preoperatively, intraoperatively, and postoperatively were collected and subjected to statistical analysis. From January 2020 to August 2023, a total of 127 patients with primary unilateral inguinal hernia were evaluated in this study, 61 in the 3D TAPP group and 66 in the 2D TAPP group. There were no statistically significant differences in baseline data, including average age, gender distribution, BMI index, hernia type, hernia defect size and location, comorbidities, and usage of anticoagulant drugs between the two groups (P > 0.05). In terms of operative indicators, the 3D group showed shorter mean operation time (51.61 ± 7.16 min vs. 78.59 ± 13.51 min, P < 0.001), mean mesh placement time (6.07 ± 1.40 min vs. 9.77 ± 1.21 min, P < 0.001), and mean peritoneal suture time (7.34 ± 1.85 min vs. 9.73 ± 1.32 min, P < 0.001) compared to the 2D group. However, there were no statistically significant differences in mean blood loss, postoperative pain scores, postoperative hospital stay, and total hospital costs between the two groups (P > 0.05). The incidence of postoperative complications did not differ significantly between the two groups (P > 0.05). No adverse reactions such as dizziness or nausea were reported by surgeons during the procedures in either group. Three-dimensional laparoscopy in TAPP surgery provides high-definition, three-dimensional surgical images, reducing the difficulty of operations and effectively shortening the operation time.

Postoperative Hydration in Children Using Intermittent Boluses of Balanced Salt Solution: Results of a Randomized Control Trial

BACKGROUND

Postoperative maintenance fluids are traditionally provided via hypotonic dextrose containing fluids administered intravenously by continuous infusion. We hypothesized that scheduled weight-based boluses of balanced salt solution would be more physiologic, reduce fluid volumes, and improve patient comfort.

METHODS

As part of an IRB-approved randomized controlled trial (Boluses of Ringer's in Surgical Kids, BRiSK), we randomized patients aged 1-21 years undergoing elective abdominal or thoracic surgery to post-operatively receive weight-based D50.45NS+20mEq/L KCl at a continuous rate or intermittent boluses of Lactated Ringer's solution until oral liquid toleration. Patients with nephropathy, diabetes, or receiving parenteral nutrition were excluded. We analyzed electrolytes, urine output, fluid volume, and adverse events.

RESULTS

We enrolled and randomized 60 patients: 29 to continuous fluids and 31 to bolus fluids. One patient from the bolus group dropped out. No patients crossed over due to difficulties with application of the bolus protocol. There were no baseline differences between groups with a mean age of 12.6 ± 1.4yr and weight of 50.9 ± 7.2 kg. There were no serious adverse events or electrolyte disturbances in either group. Patients in the bolus group received significantly less total fluid than those in the continuous group (0.43 mL/kg/h vs 1.1 mL/kg/h, p < 0.001) with no difference in urine output [1.4 ± 0.2 mL/kg/h vs 1.6 ± 0.3 mL/kg/h, p = 0.211]. There were two episodes of mild hypoglycemia in the bolus group compared to seven episodes of mild hyperglycemia in the continuous group.

CONCLUSIONS

Administration of post-operative intravenous fluids as boluses of balanced salt solution is feasible, safe, and results in significantly less fluid administered compared to a traditional continuous protocol.

Breaking Barriers: Ensuring Gender Neutral Care on Short Term Surgical Missions

INTRODUCTION

Gender discrimination is prevalent worldwide in medical and surgical care. In the setting of short-term surgical missions (STSMs) conducted to address the global burden of surgical disease, patient selection raises ethical considerations regarding equitable distribution of limited clinical resources. The goal of this study was to examine if equitable distribution of operative care between male and female patients occurs in STSMs.

METHODS

The International Surgical Health Initiative (ISHI) is a US based nonprofit, nongovernmental organization. Records from surgical missions to Ghana (2014-2023) and Sierra Leone (2013-2023) were analyzed to evaluate for gender equity in inguinal hernia repairs, the most common procedure performed. A control group was created from a literature review inclusive of all studies of inguinal hernia repairs that included over 500 patients and patient gender.

RESULTS

The review of 26 studies, representing 3,239,043 patients, demonstrated a gender distribution of 13% female. In Sierra Leone 246 inguinal hernia repairs were performed between 2013 and 2023. 28 (11.4%) of the hernia repairs were in females, which was not significantly different from the control group (P = 0.45). In Ghana 150 inguinal hernia repairs were performed between 2014 and 2023. 12 (8%) of the hernia repairs were in females. This was not significantly different from the control group (P = 0.07).

CONCLUSIONS

This is the first study investigating the gender equity conducted within the context of humanitarian surgical outreach. Equitable patient selection is a paramount consideration in STSMs, particularly to address gender-related disparities in surgical care.

Anorectal Abscess

Anorectal abscesses are a common colorectal emergency. The hallmark of treatment is obtaining source control while avoiding injury to the underlying sphincter complex. Understanding the anatomy of an anorectal abscess is critical to planning the appropriate drainage strategy and decreasing the risk of complex fistula formation. Use of antibiotics should be reserved for those with extensive cellulitis, signs of systemic infection, or patients who are immunocompromised. Whether antibiotics prevent future fistula formation is an area of active research. Primary fistulotomy at time of the index drainage is controversial; however, there may be situations where it is appropriate. It is important to counsel patients that after effective drainage of an anorectal abscess, they have a 30 to 50% chance of developing an anal fistula that will then require further treatment.

Increased risk of incisional hernia after stoma closure in patients with colorectal cancer

PURPOSE

Stoma construction and closure are common surgical strategies in patients with colorectal cancer. The present study evaluated the influence of multiple incisional sites resulting from stoma closure on incisional hernia after colorectal cancer surgery.

METHODS

The study included 1681 patients who underwent colorectal cancer surgery. Multiple incisional sites were defined as the coexistence of incisions at the midline and stoma closure sites. We retrospectively investigated the relationship between the presence of multiple incisional sites and incisional hernia development in patients with colorectal cancer.

RESULTS

Among the 1681 patients, 420 (25%) underwent stoma construction, with a stoma closure-to-construction ratio of 33% (139/420), and 155 (9.2%) developed incisional hernias after colorectal cancer surgery. In the multivariate analysis, female sex (p < 0.001), body mass index (p < 0.001), multiple incisional sites (p = 0.001), wound infection (p = 0.003), and postoperative chemotherapy (p = 0.030) were independent predictors of incisional hernia. In the multiple incisional sites group, the age (p < 0.001), surgical approach (laparoscopic) (p = 0.013), wound infection rate (p = 0.046), small bowel obstruction rate (p < 0.001), and anastomotic leakage rate (p = 0.008) were higher in those in the single incisional site group.

CONCLUSIONS

Multiple incisional sites resulting from stoma closure are associated with the development of incisional hernia following colorectal cancer surgery.

Human Capital and Productivity in Surgery Research Across the Globe: A Big Data Analysis Using Artificial Intelligence

INTRODUCTION

No investigation of each nation's contribution to knowledge production and human capital in surgery currently exists. Previous studies explored country-level research productivity only in few surgical subspecialties. To identify current and future leaders in surgery research, we conduct a retrospective observational study of each country's human capital and research productivity.

METHODS

A web-scraping algorithm was deployed on PubMed to retrieve information on the first and senior author of every publication in all PubMed-indexed surgery outlets-a total of 388 journals-between 2010 and 2022, according to the SCImago classification. Each country's human capital is proxied by the number of first and senior authors.

RESULTS

A total of 665,668 publications from 110 countries were reviewed. The number of publications rises over time. The United States represents 30.78% and 31.32% of global publications based on first and senior authors, respectively. Other leading contributors include the United Kingdom (5.57% and 5.69% of global first and senior author publications, respectively), China (8.84% and 8.74%), Japan (7.14% and 7.10%), and Italy (4.54% and 4.46%). The number of publications per 100K people ranges between 0.04 and 86.01, suggesting widely varying levels of research productivity relative to the population.

CONCLUSIONS

Our findings underscore the US dominance in surgery research. Countries with a higher share of first or senior authors may have greater capacity to expand their future research output. As big data research expands, we expect studies deploying artificial intelligence methodologies, such as web scraping, on data repositories to guide healthcare provision and health policy decisions to become mainstream.

Prospective comparison of two surgical approaches for incarcerated and strangulated inguinal hernia: preperitoneal hernioplasty through the lower abdominal median incision and laparoscope (TAPP)

The optimal surgical approach of incarcerated and strangulated inguinal hernia is controversial. Retrospective studies showed that surgical approaches through lower abdominal median incision or laparoscopic are superior to the oblique inguinal incision, respectively. Whether transabdominal laparoscopic approach is superior to the lower abdominal median incision approach needs prospective research.Prospective comparative study of patients with incarcerated and strangulated groin hernia admitted to Jinshan hospital for emergency surgery from January 2018 to June 2022. They were divided into two groups according to different surgical approach. The open preperitoneal repair group (OPR) was operated through the lower abdominal median incision. Laparoscopic preperitoneal repair group (TAPP) was completed under transabdominal laparoscope. The perioperative complications and long-term results of the two groups were compared and analyzed. Eighty-two patients met the inclusion criteria, 40 in OPR group and 42 in TAPP group. Baseline data of the two groups were comparable. Thirteen cases (15.9%) of the two groups underwent intestinal resection and anastomosis. Seventy cases (90.2%) underwent the 1st stage mesh repair, including 5 cases of preperitoneal hernioplasty after intestinal resection. The average operation time of TAPP group was 13 min longer (60.7 ± 13.7 min vs 47.8 ± 19.8 min P < 0.001), and the visual analogue scale pain score at 24 h after operation was lower (3.5 ± 1.2 vs 4.4 ± 1.7 P = 0.019) than that of OPR group. There was 1 case of bladder injury (2.5%) in OPR group and 1 case of inferior abdominal artery injury (2.4%) in TAPP group. There was no difference in the rate of the 1st stage hernioplasty between the two groups. In OPR group, 2 cases (5%) extended the incision for more than 2 cm, while in TAPP group, 1 case (2.4%) converted to laparotomy. The time of hospital stay (3.2 ± 1.8 d vs 4.3 ± 2.7 d, P = 0.036) and return to normal activities (7.9 ± 2.7 d vs 11.0 ± 4.4 d, P < 0.001) were shorter in TAPP group. The rate of total postoperative complications including chronic pain, surgical-site infection, seroma, hernia recurrence and so on was 11.9% in TAPP group, which was not significantly different from 25% in OPR group (P = 0.212). There were no cases of mesh related infection and death within 30 days in both groups.TAPP is safe and feasible for the operation of acute incarcerated inguinal hernia. TAPP had better comfort and faster recovery over open preperitoneal repair for the appropriate patients with incarcerated/strangulated inguinal hernia, which can reduce acute pain, shorten hospital stay and return to normal activities earlier.

Routine single-incision laparoscopic common bile duct exploration with concomitant cholecystectomy for elderly patients: a 6-year retrospective comparative study

BACKGROUND

While single-incision laparoscopic cholecystectomy (SILC) has gained more popularity in recent years, its application to elderly patients needs further evaluation. Few SILC studies regarded this rapidly growing vulnerable population, and single-incision laparoscopic common bile duct exploration (SILCBDE) was never mentioned. We conducted an observational study of 146 routine SILCBDE to address this issue.

METHODS

One hundred forty-six consecutive patients underwent SILCBDE with concomitant cholecystectomies during a period of 6 years (July 2012-June 2016 and July 2018-July 2020). Forty patients with an age of 65 years or older were the study target. Characteristics and operative outcomes were compared with the remaining 106 younger patients by retrospective chart review. The primary outcomes include complications and mortality, while the secondary outcomes contain intraoperative blood loss, operative time, procedural conversions, postoperative length of hospital stay, and bile duct stone recurrence.

RESULTS

There was no mortality. The bile duct stone clearance rate was 98.6%. The elderly group had higher American Society of Anesthesiologists (ASA) scores, higher comorbidity rate, higher acute cholangitis rate, lower completion intraoperative cholangiography (IOC) rate, longer operative time, more blood loss, longer postoperative hospital stay (p < .001), longer total hospital stay (p < .001), higher procedural conversion rate (p < .05), higher complication rate (p < .001), and the exclusive open conversion (2.5%). The difference in complications derived from Clavien-Dindo grade I.

CONCLUSION

Routine SILCBDE with concomitant cholecystectomy by experienced surgeons is safe and efficacious for elderly patients as for younger patients. Randomized controlled trials are anticipated.

Evaluation of the Risk Factors for the Incisional Hernia Occurrence After Robot-Assisted Laparoscopic Radical Prostatectomy

Objective: Our aim was to evaluate patient-related factors and compare the techniques used for surgical specimen removal [trocar extension (TE) and Pfannenstiel incision (PF)] in terms of incisional hernia (IH) occurrence in patients undergoing robot-assisted laparoscopic radical prostatectomy (RALRP). Materials and Methods: The records of 219 patients who underwent RALRP in our clinic between November 2017 and March 2021 were analyzed retrospectively. Postoperative complication data and functional (continence and potency status) and oncological outcomes were recorded. Hernia type, location, and treatments applied were also noted. Results: After exclusion, complete data were available on 192 patients undergoing RALRP between the specified dates. The TE technique for removing the surgical specimen was performed in 135 patients, and the lower abdominal transverse incision technique (PF) in 57 patients. Preoperative patient- and tumor-related characteristics (age, body mass index [BMI], American Society of Anesthesiologists (ASA) score, T stage, and prostate size) were similar in both surgical groups. IH was detected in 16 patients (14 in the TE group and 2 in the PF group) (P = .156). Thirteen patients underwent surgery for IH, and three were followed up clinically. Conclusion: In our study, no statistically significant demographic or surgical technique-related factors were found to explain the occurrence of IH in patients who underwent RALRP for prostate cancer. It was observed that IH occurred more frequently in the cases where the surgical specimen was removed with the TE technique compared with the PF incision, but this result was not statistically significant. There was also no statistically significant difference between these two groups regarding oncological and functional outcomes in the early postoperative period.

Comparative Assessment Between the Fundus-First Technique and Standard Laparoscopic Technique in Difficult Laparoscopic Cholecystectomy

BACKGROUND

Laparoscopic cholecystectomy is a standard minimally invasive technique for the treatment in gallstone disease. In difficult laparoscopic cholecystectomies, bailout strategies have been developed of which the fundus-first technique is one. The present study aims to compare the outcomes of the fundus-first technique against the standard laparoscopic approach in managing difficult cholecystectomy cases by focusing on intraoperative factors such as bleeding, bile duct injury, operative time, and postoperative complications like biliary leakage.

METHODS

A prospective comparative study was conducted over a period of two years (June 2022-May 2024) with 200 consecutive patients. All patients were classified as difficult cases based on the Tokyo 2018 guidelines. Detailed data collection included patient history, physical examination, laboratory investigations, and operative findings. The study's follow-up period was six weeks.

RESULTS

The fundus-first technique demonstrated significant advantages, with a reduction in operative time, fewer intraoperative complications, and better operative outcomes compared to the standard approach. Patients in the fundus-first group had a mean operative time of 91.50 minutes as compared to 143.75 minutes in the standard group (p < 0.001) and 88% completed operative outcome vs 51%(p < 0.001). No significant differences were observed in postoperative complications such as bile leakage and bleeding between the two groups.

CONCLUSION

The fundus-first technique offers a safer and more efficient alternative to the standard approach in difficult laparoscopic cholecystectomy cases. By allowing better access to Calot's triangle, this method proves to be an effective bailout strategy, despite its steep learning curve. Further studies are needed to validate these findings and explore the broader application of the fundus-first technique in gallbladder surgeries.

Outcomes of Gallbladder Drainage Techniques in Acute Cholecystitis: Percutaneous Versus Endoscopic Methods

Acute cholecystitis, often caused by gallstones obstructing the cystic duct, is a potentially life-threatening condition that requires timely intervention. High-risk patients, particularly those with significant comorbidities, may not be suitable candidates for laparoscopic cholecystectomy, necessitating alternative drainage techniques such as percutaneous cholecystostomy (PC) and endoscopic gallbladder drainage (EGD). This systematic review aims to compare the efficacy, safety, and outcomes of PC and EGD in managing acute cholecystitis in high-risk surgical patients. A comprehensive literature search was conducted across multiple databases, including PubMed, Medline, Embase, Cochrane Library, and Scopus, from inception to October 2024. Studies were included if they assessed the outcomes of PC versus EGD in high-risk patients with acute cholecystitis. Data extraction focused on primary outcomes such as complication rates, reintervention needs, symptom resolution, hospital stay duration, and mortality. A qualitative synthesis was conducted due to heterogeneity in the study designs. Four randomized controlled trials and cohort studies were included, encompassing a total of 238 high-risk patients. Laparoscopic cholecystectomy showed significantly better outcomes compared to percutaneous drainage in reducing major complications, reintervention rates, and recurrent biliary disease. Endoscopic drainage techniques, including naso-gallbladder drainage and gallbladder stenting, demonstrated similar clinical success rates with fewer complications than percutaneous methods, particularly in patients with concurrent biliary conditions. The findings suggest that while percutaneous drainage provides rapid symptom relief, it is associated with higher reintervention rates. Endoscopic techniques offer fewer complications and are particularly beneficial for patients with suspected choledocholithiasis. However, the choice of drainage method should be based on individual patient profiles, taking into account overall health status and comorbidities. Both percutaneous and endoscopic drainage methods are effective in managing acute cholecystitis in high-risk patients, with distinct advantages depending on patient-specific factors. Further research is needed to explore long-term outcomes and hybrid approaches that may optimize care for these patients.

Derivation and validation of a predictive model for subtotal cholecystectomy

INTRODUCTION

Rates of subtotal cholecystectomy (STC) are increasing in response to challenging cases of laparoscopic cholecystectomy (LC) to avoid bile duct injury, yet are associated with significant morbidity. The present study identifies risk factors for STC and both derives and validates a risk model for STC.

METHODS

LC performed for all biliary pathology across three general surgical units were included (2015-2020). Clinicopathological, intraoperative and post-operative details were reported. Backward stepwise multivariable regression was performed to derive the most parsimonious predictive model for STC. Bootstrapping was performed for internal validation and patients were categorised into risk groups.

RESULTS

Overall, 2768 patients underwent LC (median age, 53 years; median ASA, 2; median BMI, 29.7 kg/m2), including 99 cases (3.6%) of STC. Post-operatively following STC, there were bile leaks in 29.3%, collections in 19.2% and retained stones in 10.1% of patients. Post-operative intervention was performed in 29.3%, including ERCP (22.2%), laparoscopy (5.0%) and laparotomy (3.0%). The following variables were positive predictors of STC and were included in the final model: age >  60 years, male sex, diabetes mellitus, acute cholecystitis (AC), increased severity of AC (CRP > 90 mg/L), ≥ 3 biliary admissions, pre-operative ERCP with/without stent, pre-operative cholecystostomy and emergency LC (AUC = 0.84). Low, medium and high-risk groups had a STC rate of 0.8%, 3.9% and 24.5%, respectively.

DISCUSSION

The present study determines the morbidity of STC and identifies high-risk features associated with STC. A risk model for STC is derived and internally validated to help surgeons identify high-risk patients and both improve pre-operative decision-making and patient counselling.

Surgical unit volume and reoperation for recurrence following total extraperitoneal groin hernia repairs: nationwide population-based register study

BACKGROUND

The quality of total extraperitoneal groin hernia repair and recurrence rates are influenced by various factors, potentially including the annual surgical unit volume of repairs. The precise nature of this relationship remains unclear. The aim of this study was to investigate the influence of surgical unit volume on reoperation rates for recurrence following total extraperitoneal groin hernia repair.

METHODS

This observational nationwide population-based study utilized prospectively collected data from the Swedish Hernia Register. Patients aged 15 years old or older who underwent a total extraperitoneal groin hernia repair from 1 January 2015 to 31 August 2019 were eligible. Follow-up time was until 31 August 2022. Surgical units were grouped into low-volume (fewer than 12 repairs per year), low-medium-volume (12-50 repairs per year), medium-high-volume (greater than 50-150 repairs per year), and high-volume (greater than 150 repairs per year) units. The primary outcome was reoperation for recurrence. The secondary outcome was postoperative complications.

RESULTS

A total of 20 656 elective total extraperitoneal groin hernia repairs were included across 75 surgical units. The reoperation rate for recurrence was higher in all three lower-volume groups (low-volume, 5.3%; low-medium-volume, 3.8%; and medium-high-volume, 3.5%) compared with the high-volume group (2.9%). Adjusted multivariable Cox regression analysis revealed a statistically significant increased HR for reoperation for recurrence in the low-volume group (1.87 (95% c.i. 1.31 to 2.67)) and the low-medium-volume group (1.32 (95% c.i. 1.07 to 1.62)) compared with the high-volume group. No difference was seen between the groups regarding the risk of postoperative complications.

CONCLUSION

The risk of reoperation for recurrence following total extraperitoneal groin hernia repair is significantly increased in surgical units that perform fewer than 51 repairs per year. The findings may influence guidelines on required annual surgical unit volume to improve patient outcomes following total extraperitoneal groin hernia repair.

Robotic-assisted surgical treatment of complex giant incisional hernias: A report of 3 cases

Incisional hernia of abdominal wall is one of the most common complications following open surgery. Giant incisional hernia of abdominal wall is defined as having a maximum defect diameter >12 cm or a hernia sac volume-to-abdominal cavity volume ratio >20%. The Primary treatment for giant incisional hernia of abdominal wall is surgical repair; however, both open surgery and conventional laparoscopic surgery are associated with significant technical difficulty, high surgical trauma, frequent postoperative complications, and suboptimal outcomes. From May 2021 to November 2023, 3 patients with giant incisional hernia of abdominal wall were treated at the Third Xiangya Hospital of Central South University with robotic-assisted intraperitoneal onlay mesh repair using the da Vinci surgical system. These patients experienced minimal intraoperative bleeding, rapid postoperative recovery, no wound infections or severe complications, and no recurrences. Compared with traditional open and laparoscopic surgeries, robotic-assisted surgery demonstrates unique advantages in the clinical management of giant incisional hernias.

Worse cholecystectomy outcomes during the COVID-19 pandemic: were staff shortages or a change in patient case-mix the culprit?

BACKGROUND

The COVID-19 pandemic has profoundly impacted the field of surgery, mostly through infectious risks, staff shortages, reduced hospital capacities, and changed patient pathways. Prompted by an increase in wound complications, we performed an in-depth analysis of an example surgical procedure.

METHODS

A consecutive cohort of 195 patients undergoing laparoscopic cholecystectomy was studied retrospectively. Data of patients receiving cholecystectomy before, during, and after the peak of the pandemic were compared. The potential influence of patient characteristics, pandemic phase, and staffing level (surgeons and nurse assistants) was analyzed statistically. In the primary analyses, the composite measure of a 'textbook outcome' was examined, which was defined as no relevant complication, hospital stay < 5 days, and no readmission.

RESULTS

During the COVID-19 phase, acute biliary disease was more common than in the pre-COVID-19 phase (62% vs. 30%). In 35% of cases, no qualified operating room nurse was available. Intraoperative features and postoperative complication rates were increased (bile spillage in 46%, wound complications in 24%). A 59-year-old male admitted with acute cholecystitis during COVID-19 died of wound-related septic shock. Multivariate analysis confirmed the acuity of gallbladder inflammation (odds ratio 5.3) and old age (2.6) as risk factors for a non-textbook outcome. The absence of qualified nursing staff was clearly associated with a non-textbook outcome (odds ratio 3.3).

CONCLUSIONS

The fact that laparoscopic cholecystectomy outcomes were worse during COVID-19 can be partly attributed to a change in patient case-mix, but the shortage of qualified nursing staff in the operating room also had a strong negative influence.

The Evolving Applications of Laparoscopic Intracorporeal Rectus Aponeuroplasty (LIRA) in Ventral Hernia Repair-A Systematic Review

Purpose

Laparoscopic intracorporeal rectus aponeuroplasty (LIRA), emerged as a method that combines benefits from minimally invasive and abdominal wall reconstruction with defect closure, restoring the midline without tension by folding the posterior aponeurosis of both abdominal rectus muscles and using intraperitoneal mesh repair. We aimed to perform a systematic review of the existing evidence on LIRA results and potential applications.

Source

A thorough search of Cochrane Central, Scopus, SciELO, LILACS, and PubMed/MEDLINE, focusing on studies that explored LIRA's possible applications and results was performed. Key outcomes evaluated included recurrence, seroma, hematoma, surgical site infection (SSI), and length of hospital stay. We included both analytic data and descriptive studies.

Principal Findings

Out of 128 screened studies, three met the inclusion criteria and comprised 113 patients, of which 69 (61.1%) were operated using LIRA. Three studies comprised two case series of conventional and robotic LIRA repair, and one comparative study of LIRA versus intraperitoneal underlay mesh repair (IPUM plus). No surgical site infections were reported. Seroma rates ranged between 11.1% and 50%, while no bleeding or hematoma was noted. There were no patients presenting recurrence in a median follow-up ranging from 12 to 15 months, despite the comparative study reporting a 4.4% rate of bulging without clinical recurrence. The mean length of hospital stay ranged from 12 to 36 h. LIRA presented no differences in postoperative complications compared to the IPUM plus technique.

Conclusion

LIRA is linked to low recurrence and postoperative complications. It is a novel approach with potential applications in various types of primary and incisional ventral hernias.

Long-term outcomes and quality of life in patients with Hirschsprung disease

Although patients with Hirschsprung disease are mostly affected by imperfect bowel function and fecal control in the long term, they are also predisposed to lower urinary tract symptoms, impaired sexual functions, infertility, psychosocial issues, and decreased quality of life. Rare, but notable comorbidities, which may manifest after childhood, include inflammatory bowel disease and familial medullary thyroid cancer. Despite frequent occurrence of fecal incontinence and constipation, the overall long-term outlook is quite optimistic as social continence with a good quality of life can be achieved by efficient bowel management also in those affected patients, whose self-coping strategies and medical treatment remain insufficient. Bowel dysfunction and other potential long-term complications are best managed by an interdisciplinary specialized approach not overlooking psychosocial issues, which also helps to correctly identify areas requiring continuing input by adult healthcare for young adult patients after transition. Additional research is needed to unravel the pathophysiological mechanisms of the long-term bowel dysfunction to identify novel therapeutic targets for development of more efficient innovative management strategies and thereby improvement of quality of life.

The impact of periampullary diverticula on cannulation and adverse events in endoscopic retrograde cholangiopancreatography

Background

Periampullary diverticulum (PAD) is commonly encountered in endoscopic retrograde cholangiopancreatography (ERCP) procedures.

Objectives

We sought to determine whether PADs are associated with a lower success rate of cannulation and an increased risk of adverse events.

Design

A retrospective cohort study was conducted using prospectively gathered nationwide registry data.

Methods

Using the Swedish registry for gallstone surgery and ERCP, we analyzed a cohort of 66,974 prospectively registered ERCP procedures performed in 2006-2021. The presence of PAD was divided into two groups based on the PAD type: Boix type 1 (the papilla located inside the PAD) and Boix types 2-3 (the papilla located either at the edge of the PAD or immediately adjacent to the PAD). The primary outcomes were the success rate of cannulation and overall adverse events within 30 days.

Results

PADs were registered in 8130 (12.1%) of ERCPs included in the study population. In total, 2114 (3.9%) patients had Boix type 1 PAD, while 5035 (8.2%) patients had Boix type 2 or 3 PAD. The chance of successful cannulation was lower in patients with type 1 PAD compared to no PAD (80.1% vs 88.7%; odds ratio: 0.42, 95% confidence interval: 0.38-0.46). No differences were seen in overall adverse events or post-ERCP pancreatitis. Adverse events occurred in 14.6% of patients with PAD type 1 and 16.0% of patients with PAD type 2 or 3, compared to 16.5% of patients without a PAD.

Conclusion

Cannulation appears less successful during ERCP when the papilla is located in the PAD (i.e., type 1). Adverse events seem not to increase with the presence of a PAD, but they could theoretically be influenced by the inability to cannulate.

Effect of the Green Cross method on patient safety culture in a postanaesthesia care unit: a longitudinal quasi-experimental study

BACKGROUND

Hospitals should adopt multiple methods to monitor incidents for a comprehensive review of the types of incidents that occur. Contrary to traditional incident reporting systems, the Green Cross (GC) method is a simple visual method to recognise incidents based on teamwork and safety briefings. Its longitudinal effect on patient safety culture has not been previously assessed. This study aimed to explore whether the implementation of the GC method in a postanaesthesia care unit changed nurses' perceptions of different factors associated with patient safety culture over 4 years.

METHODS

A longitudinal quasi-experimental pre-post intervention design with a comparison group was used. The intervention unit and the comparison group, which consisted of nurses, were recruited from the surgical department of a Norwegian university hospital. The intervention unit implemented the GC method in February 2019. Both groups responded to the staff survey before and then annually between 2019 and 2022 on the factors 'work engagement', 'teamwork climate' and 'safety climate'. The data were analysed using logistic regression models.

RESULTS

Within the intervention unit, relative to the changes in the comparison group, the results indicated significant large positive changes in all factor scores in 2019, no changes in 2020, significant large positive changes in 'work engagement' and 'safety climate' scores in 2021 and a significant medium positive change in 'work engagement' in 2022. At baseline, the comparison group had a significantly lower score in 'safety climate' than the intervention unit, but no significant baseline differences were found between the groups regarding 'work engagement' and 'teamwork climate'.

CONCLUSION

The results suggest that the GC method had a positive effect on the nurses' perception of factors associated with patient safety culture over a period of 4 years. The positive effect was completely sustained in 'work engagement' but was somewhat less persistent in 'teamwork climate' and 'safety climate'.

Background

Individuals from all over the world are increasingly using the internet to purchase sex toys and gadgets to enhance their sexual experience and provide variety and excitement to their sexual encounters.

Aim

This study examined the trends about the most popular preferred sex toys by nation/region from 2009 using data from Google Trends (GT).

Methods

GT was used to generate a "line-graph" that displays how interest in a topic in certain places has risen or diminished over time. Search terms were generated for vibrator, dildo, anal plug, strap-on, and masturbator. The data were included "globally" from January 1, 2009 to June 30, 2023.

Outcomes

The search values for certain terms were indexed using the relative search volume (RSV), which is shown on a scale of 0-100.

Results

In the linear regression analysis, the trends by strength were sorted as follows: dildo, vibrator, strap-on, anal plug, and masturbator. In 2018, vibrator surpassed strap-on and came in second, while the regression analysis showed a positive trend for dildo between 2009 and 2016 (P = .014). It had a negative trend after 2016. Strap-on was the only one to have a downward trend (P = .029). Regression analysis revealed positive trends for vibrator and masturbator (P = .030, P = .045). The upward trends have continued uninterruptedly since 2009.

Clinical implications

According to our research, interest in online trends relating to sex toys has increased along with advancements in technology and clinical applications. This rise is linked to the worldwide sex toy industry's development in response to consumer demand and ease of accessibility.

Strengths and limitations

This is the first research of this sort, looking into the interests of internet users about sex toys by country over time using GT. GT data is anonymous, and analysis of subpopulation groups is not possible.

Conclusion

Individual preferences for sex toys have different trends on different continents around the world. The compatibility of sex toys with technology over time, their clinical use, and sex toy-related injuries play an important role in the selection process. Web trends seem appropriate to reflect how the demand for sex toys has changed over time.

Outcomes of elective and emergency surgical repair of incisional hernia: a comparative observational study

PURPOSE

Incisional hernia (IH) is a common complication following abdominal surgery. Surgical repair of IH is associated with the alleviation of symptoms and improvement of quality of life. Operative intervention can pose a significant burden to the patient and healthcare facilities. This study aims to describe and compare outcomes of elective and emergency surgical repair of IH.

METHODS

This study is a single-centre comparative retrospective study including patients who had repair of IH. Patients were divided into Group I (Emergency) and Group II (Elective), and a comparison was conducted between them.

RESULTS

Two hundred sixty-two patients were identified with a mean age of 61.8 ± 14.2 years, of which 152 (58%) were females. The mean BMI was 31.6 ± 7.2 kg/m2. More than 58% had at least one comorbidity. 169 (64.5%) patients had an elective repair, and 93 (35.5%) had an emergency repair. Patients undergoing emergency repair were significantly older and had higher BMI, p = 0.031 and p = 0.002, respectively. The significant complication rate (Clavien-Dindo III and IV) was 9.54%. 30 and 90-day mortality rates were 2.3% (n = 6) and 2.68% (n = 7), respectively. In the emergency group, the overall complications, 30-day and 90-day mortality rates were significantly higher than in the elective group, p ≤ 0.001, 0.002 and 0.001, respectively. Overall, 42 (16.1%) developed wound complications, 25 (9.6%) experienced a recurrence, and 41 (15.71%) were readmitted within 90 days, without significant differences between the two groups.

CONCLUSION

Patients who underwent emergency repair were significantly older and had a higher BMI than the elective cases. Emergency IH repair is associated with higher complication rates and mortality than elective repair.

Relationships of diastasis recti abdominis with stress urinary incontinence and pelvic floor muscle dysfunction in postpartum women

OBJECTIVES

To determine whether diastasis of the rectus abdominis muscles was related to stress urinary incontinence, dysfunction of pelvic floor muscles, and of hiatal area size in postpartum women.

STUDY DESIGN

This observational prospective study included 150 women from 6 weeks to 6 months postpartum, with a mean age of 33.1 years. Diastasis Recti Abdominis is a condition in which the abdominal muscles are separated by an increased inter-rectus distance due to widening of the linea alba, measured using 2D ultrasound. Pelvic floor muscle function was examined using manometry, and the size of the hiatal area was examined using 3D/4D ultrasonography. Stress urinary incontinence symptoms were assessed using the International Incontinence Consultation Questionnaire (ICIQ-UI SF).

RESULTS

We identified a significant weak correlation between diastasis of the rectus abdominis and symptoms of stress urinary incontinence (r = 0.283). We also found weak significant correlations of diastasis of the rectus abdominis with the maximum voluntary contraction (r = -0.278) and with the duration voluntary contraction (r = -0.274). No correlation was found between diastasis of the rectus abdominis and size of the hiatal area.

CONCLUSIONS

Diastasis of the rectus abdominis was weakly related to stress urinary incontinence and also to pelvic floor muscle dysfunction.

Recurrence Rates after Primary Femoral Hernia Open Repair a Systematic Review

PURPOSE

Femoral hernia accounts for 22% of groin hernia operations in women and for 1.1% in men. Numerous surgical approaches have been reported but there is no consensus. Many of the recurrence rates are reported in old literature, while recent reports are scarce. The aim of the present study was to review rates of recurrences in patients who underwent open repair of a primary femoral hernia.

METHODS

We conducted a systematic search in the electronic literature, using the search terms "femoral hernia" and "recurrence". We included studies published from 2002 that had as primary or secondary endpoint to evaluate the recurrence after surgery. Risk of bias was assessed by the Cochrane risk of bias tool for RCT and by the Newcastle-Ottawa Scale for cohort studies.

RESULTS

Fifteen eligible articles were included in our systematic review. A total of 1087 procedures were performed according to the defined criteria. The metanalytic evaluation highlighted a higher probability of recurrence for non-mesh than mesh repairs (6.5% vs 1.9%; RR 0.924, 95% CI: 0.857 - 0.996). In patients treated in emergency settings the rate of recurrences was 3.7%; in patients who received elective repairs it was 0.71%. Six studies reported that most of recurrences occurred within the first post-operative year.

CONCLUSION

We found that crude recurrence rate after open repair of a primary femoral hernia is about 4%. This rate is higher in case of non-mesh techniques and in emergency surgery. Our results support the recommendation that femoral hernias should be repaired with mesh techniques.

The effect of deprescribing interventions on mortality and health outcomes in older people: An updated systematic review and meta-analysis

AIMS

Previous systematic reviews suggest that deprescribing may improve survival, particularly in frail older people. Evidence is rapidly accumulating, suggesting a need for an updated review of the literature.

METHODS

We updated a 2016 systematic review and meta-analysis to include studies published from inception to 26 April 2024 from specified databases. Studies in which older people had at least one medication deprescribed were included and grouped by study designs and targeted medications. The risk of bias was assessed using the Cochrane tool and the Newcastle-Ottawa tool. Odds ratios (OR) or mean differences were calculated as the effect measures using either the Mantel-Haenszel or generic inverse-variance method with fixed- or random-effects meta-analyses. The primary outcome was mortality. Secondary outcomes were adverse drug withdrawal events, physical health, cognitive function, quality of life and effect on medication regimen. Subgroup analyses were performed based on age and intervention types.

RESULTS

A total of 259 studies (reported in 286 papers) were included in this updated review. Deprescribing polypharmacy did not result in a significant reduction in mortality in both randomized (OR 0.96, 95% confidence interval [CI] 0.84-1.09) and non-randomized studies (OR 0.70, 95% CI 0.36-1.38). Further subgroup analyses of randomized studies on deprescribing polypharmacy demonstrated a significant reduction in mortality in the young old (aged 65-79) (OR 0.71, 95% CI 0.51-0.99) and when patient-specific interventions were applied (OR 0.79, 95% CI 0.63-0.99).

CONCLUSIONS

Deprescribing can be achieved with potentially important benefits in terms of improved survival, particularly when patient-specific interventions are applied and initiated early in the young old.

Impact of Surgical Timing on Outcomes in Patients With Acute Cholecystitis: A Systematic Review

This study aims to conduct a thorough analysis of the existing studies to determine how patients with acute cholecystitis (AC) respond to surgical intervention at different times following their diagnosis. To locate studies that met the inclusion criteria, a thorough computerized search of relevant databases was carried out. A comprehensive search was carried out on PubMed, SCOPUS, Science Direct, Cochrane Library, and Web of Science to locate relevant material. Our data included seven trials with 48,747 patients: 40,955 in the early laparoscopic cholecystectomy (ELC) group and 7,792 in the delayed laparoscopic cholecystectomy (DLC) group. More than half of the participants (27,687, 56.8%) were female. ELC was found to be safe regardless of when symptoms first appeared, challenging previous assumptions that surgery should be delayed during the initial symptomatic period. Mortality rates for ELC were consistently low, ranging from 0% to 3.9% in all groups, while complication rates varied from 3.5% to 12.5% in all groups as well. Although DLC is still considered safe, the likelihood of complications such as bile duct damage and surgical site infections appeared to increase, particularly in patients who underwent surgery more than three days after the diagnosis of cholecystitis. It is important to note that ELC refers to surgery performed within the first three days after diagnosis, while DLC refers to surgery performed after three days. The systematic review reveals that ELC is a secure and successful remedy for sudden cholecystitis, offering superior outcomes compared to DLC. ELC is associated with lower complication rates, reduced hospital stays, and minimal mortality, suggesting it should be the preferred approach in most cases (performing the surgery within the first three days following the diagnosis of AC). While DLC remains a viable option, particularly for certain patient populations, it carries a higher risk of complications and prolonged recovery times.

Perioperative and Patient-Reported Clinical Outcomes of Robotic Versus Laparoscopic Cholecystectomy

Background

There is a lack of clinical evidence from India that compare robotic-assisted cholecystectomy (RAC) with laparoscopic cholecystectomy (LC).

Methods

This prospective, single-center study compares the short-term perioperative outcomes of RAC against LC. Consecutive patients who were 18 years or older, provided informed consent, and were found to be eligible for multiport RAC or multiport LC were included in the study.

Results

A total of 120 patients were enrolled in this study (n = 80, LC group; n = 40, RAC group). The most common preoperative indication was symptomatic cholelithiasis (80% in the LC group and 52.5% in the RAC group). The mean length of hospital stay was comparable for the RAC and LC groups (1.08 ± 0.26 vs 1.13 ± 0.33 days, P = .406). The mean operative time was also similar between the groups (38.06 ± 9.23 minutes in the LC group vs 40 ± 9.78 minutes in the RAC group, P = .290). Within each group, there were no conversions, intraoperative complications, bile duct injuries, surgical site infections, or mortality at day 30 postsurgery. There was just one postoperative complication in the study population (in the LC group). On postoperative days 4 and 7, the RAC group reported significantly lower pain than the LC group (P = .0000 and P = .0122, respectively). In addition, the RAC group returned to work faster than the LC group (P = .0000).

Conclusion

Our findings indicate that RAC and LC have comparable perioperative outcomes. There are advantages to the RAC approach in terms of postoperative pain and resumption of work.

Minimally Invasive Pelvic and Acetabular Surgery: Case Report of a Robot-Assisted Osteosynthesis of an Open-Book Injury of the Pelvic Ring

BACKGROUND

In recent years, endoscopic treatment of pelvic ring injuries has emerged. In addition to the complex 3D anatomy of the bony pelvis, a particular challenge is its embedding in the surrounding soft tissue structures. It is known from other surgical specialties that the preparation can be facilitated by using surgical robot systems.

MATERIALS AND METHODS

In a patient with an open-book injury of the pelvic ring, a symphysis plate was performed using the DaVinci system.

RESULTS

We describe the robotic-assisted osteosynthesis on the anterior pelvic ring with available instruments.

CONCLUSION

The further development of minimally invasive surgical techniques is always linked to the development of new instruments. For trauma surgery, this means in particular the reduction of dislocated fractures. If appropriate techniques and instruments are developed here, minimally invasive treatment of injuries to the pelvic ring or acetabulum may represent an alternative to open procedures in the future.

Standardization of the strategy for open abdomen in nontrauma emergency laparotomy: A prospective study of outcomes in primary versus temporary abdominal closure

BACKGROUND

The indications for temporary abdominal closure in nontrauma surgery are heterogeneous and with limited data on clinical outcomes. This study aimed to report the outcomes of primary closure compared with temporary abdominal closure after nontrauma emergency laparotomy within a standardized clinical setting adapted from international guidelines.

METHODS

Included were all nontrauma patients undergoing emergency laparotomy between January 1, 2021, and December 31, 2022, at Copenhagen University Hospital Herlev in Denmark. All patients received treatment on the basis of standardized bundle of care trajectory for major emergency abdominal surgery. Mortality, risks of re-laparotomy, and postoperative complications were assessed using Kaplan-Meier plots and multiple logistic regression modeling.

RESULTS

Of the 576 included patients, temporary abdominal closure was performed in 57 (10%) patients in the initial surgery. Indications for temporary abdominal closure included damage control strategy as the result of considerable hemodynamic instability in 21 (37%) patients, need for reassessment of bowel viability in 21 (37%) patients, and loss of domain in 15 (25%) patients. Fascial closure was achieved after a median period of 2 days. Sixty-seven patients (12%) underwent re-laparotomy, with temporary abdominal closure performed in 10 (15%) of the cases. Patients with temporary abdominal closure had a significantly greater risk of postoperative complications (odds ratio 2.58, 95% confidence interval 1.38-4.89, P = .003). There were no significant differences in the risks of fascial dehiscence, re-laparotomy, or 30- or 90-days mortality.

CONCLUSION

Temporary abdominal closure was performed in 10% of patients undergoing nontrauma emergency laparotomy, with the primary indications being damage control strategy and need for reassessment of bowel viability. Patients undergoing temporary abdominal closure had a significantly greater risk of postoperative complications.

Treatment of Persistent Soiling in Hirschsprung Disease With Antegrade Continence Enemas

INTRODUCTION

Patients with Hirschsprung disease (HD) can experience soiling after their pull-through. We evaluated the use of antegrade continence enema (ACE) for this patient population and investigated the timing and factors associated with getting the patient clean.

METHODS

We performed a single-institution retrospective review (from January 2020 to January 2023) of patients with HD and prior pull-through who had persistent soiling, failed laxative treatment or rectal enemas, and were treated with antegrade enemas. The primary outcome was time to become "clean of stool" which was defined as at least one bowel movement per day, no more than one stool accident per week, and no significant stool burden radiographically. Kaplan-Meier survival analysis was performed, and univariate cox proportional hazard regression was used to assess factors associated with time to continence.

RESULTS

Thirty patients who met the criteria underwent ACE creation at a median age of 6.5 y (interquartile range 5.3-9.8) with a median follow-up time of 11.5 mo (interquartile range 5.6-16.5). Most patients became clean by 4 mo (13 of 20, 65%) with similar results at 1-y follow-up (16 of 21, 76%). The median time to becoming clean was 4.3 mo (95% confidence interval: 1.7-15.0. Patients with hypermotility were more likely to continue to soil at 1 y (80% versus 13%, P = 0.01). There were no additional factors significantly associated with time to cleanliness.

CONCLUSIONS

ACE is a useful modality for HD patients with soiling. Most became clean of stool in 4 mo. The presence of hypermotility was associated with a higher incidence of persistent soiling at 1 y.

Multicenter analysis of the efficacy of early cholecystectomy and preoperative cholecystostomy for severe acute cholecystitis: a retrospective study of data from the multi-institutional database of the Hiroshima Surgical Study Group of Clinical Oncology

BACKGROUND

Severe acute cholecystitis (AC) is a challenging disease because it comprises coexisting systemic infections that lead to vital organ dysfunction. This study evaluated the optimal surgical timing and efficacy of preoperative percutaneous cholecystostomy (PC) for patients with severe AC.

METHODS

Data of 142 patients who underwent cholecystectomy for severe AC between 2011 and 2021 were retrospectively collected from the multi-institutional database of the Hiroshima Surgical Study Group of Clinical Oncology. Patients were divided into the early cholecystectomy (EC) group (within 72 h of symptom onset) and delayed cholecystectomy (DC) group. They were also subdivided into the upfront cholecystectomy group and preoperative PC before cholecystectomy group. The diagnosis and severity of AC were graded according to the Tokyo Guidelines 2018. Clinicopathological variables and outcomes were compared.

RESULTS

No significant differences in age, body mass index, American Society of Anesthesiologists (ASA) classification, and Charlson comorbidity index between the EC and DC groups were observed. Preoperative drainage was more commonly performed for the DC group than for the EC group. Local severe AC features were more commonly detected in the DC group than in the EC group. The postoperative outcomes of the EC and DC groups were comparable. Compared to the PC before cholecystectomy group, the upfront cholecystectomy group included more patients with ASA physical status ≥ 3 and more patients who used oral warfarin. Warfarin usage and cardiovascular dysfunction rates of the PC after cholecystectomy group were higher than those of the upfront cholecystectomy group. PC was associated with significantly less intraoperative bleeding and shorter hospital stays.

CONCLUSIONS

Patients who can tolerate general anesthesia are good candidates for EC. Patients who use warfarin and those with cardiovascular dysfunction are considered to be at high risk for postoperative complications; therefore, to prevent AC recurrence during the waiting period, PC before cholecystectomy during the same admission is more appropriate than upfront cholecystectomy for these patients.

Healthcare as a driver, reservoir and amplifier of antimicrobial resistance: opportunities for interventions

Antimicrobial resistance (AMR) is a global health challenge that threatens humans, animals and the environment. Evidence is emerging for a role of healthcare infrastructure, environments and patient pathways in promoting and maintaining AMR via direct and indirect mechanisms. Advances in vaccination and monoclonal antibody therapies together with integrated surveillance, rapid diagnostics, targeted antimicrobial therapy and infection control measures offer opportunities to address healthcare-associated AMR risks more effectively. Additionally, innovations in artificial intelligence, data linkage and intelligent systems can be used to better predict and reduce AMR and improve healthcare resilience. In this Review, we examine the mechanisms by which healthcare functions as a driver, reservoir and amplifier of AMR, contextualized within a One Health framework. We also explore the opportunities and innovative solutions that can be used to combat AMR throughout the patient journey. We provide a perspective on the current evidence for the effectiveness of interventions designed to mitigate healthcare-associated AMR and promote healthcare resilience within high-income and resource-limited settings, as well as the challenges associated with their implementation.

Computed tomography for evaluation of abdominal wall hernias-what is the value of the Valsalva maneuver?

PURPOSE

To investigate the differences in the visibility and size of abdominal wall hernias in computed tomography (CT) with and without Valsalva maneuver.

METHODS

This single-center retrospective study included consecutive patients who underwent abdominal CTs with Valsalva maneuver between January 2018 and January 2022. Inclusion criteria was availability of an additional non-Valsalva CT within 6 months. A combined reference standard including clinical and surgical findings was used. Two independent, blinded radiologists measured the hernia sac size and rated hernia visibility on CTs with and without Valsalva. Differences were tested with a Wilcoxon signed rank test and McNemar's test.

RESULTS

The final population included 95 patients (16 women; mean age 46 ± 11.6 years) with 205 hernias. Median hernia sac size on Valsalva CT was 31 mm compared with 24 mm on non-Valsalva CT (p < 0.001). In 73 and 82% of cases, the hernias were better visible on CT with Valsalva as compared to that without. 14 and 17% of hernias were only visible on the Valsalva CT. Hernia visibility on non-Valsalva CT varied according to subtype, with only 0 and 3% of umbilical hernias not being visible compared with 43% of femoral hernias.

CONCLUSIONS

Abdominal wall hernias are larger and better visible on Valsalva CT compared with non-Valsalva CT in a significant proportion of patients and some hernias are only visible on the Valsalva CT. Therefore, this method should be preferred for the evaluation of abdominal wall hernias.

Redefining Abdominal Contours: An Analysis of Medium Definition Liposuction Abdominoplasty

INTRODUCTION

This study elucidates the application of Medium Definition Liposuction Abdominoplasty, a novel technique for achieving well-defined abdominal contours. The technique focuses on revealing the patient's inherent muscular volume and form by creating thinner flaps compared to traditional liposuction methodologies.

METHODS

Objective evaluations of the abdominal wall's configuration were systematically executed both pre- and post-intervention for each participant. Digital image measurements facilitated by an image software constituted the basis for these assessments. The Body Fat Index was computed using precise measurements from seven distinct anatomical sites, with two measurements taken at each site and subsequently averaged.

RESULTS

Over a span of 63 months, 300 patients underwent this combined procedure, resulting in discernible enhancements in the configuration of their abdominal walls in 97.6% of cases. However, complications such as partial diminution of tension in the muscular wall (2%), distal flap necrosis (0.6%), and minor muscular hernia (0.3%) were observed.

CONCLUSION

The employment of combined muscle plication emerges as an efficacious methodology in meticulously rectifying alterations inherent within the muscular aponeurotic abdominal wall. This technique ensures the preservation of the original anatomical structure and functional dynamics, thereby circumventing the manifestation of local distortions that may arise from inadequate or excessive corrections.

Postoperative Outcomes and Recurrence Rate in Laparoscopic Tep Inguinal Hernia Repairs Using Partially Absorbable Meshes: A Retrospective Single-Surgeon Study Over a 5-Year Period

Objectives

This study aimed to evaluate the postoperative outcomes and recurrence rate in laparoscopic inguinal hernia repairs performed over a 5-year period with totally extraperitoneal (TEP) technique and use of partially absorbable meshes.

Methods

A total of 100 patients (mean (SD, min-max) age: 51.0 (14.6, 16-83) years, 91.0% were males) who underwent 150 laparoscopic TEP inguinal hernia repairs (bilateral in 50 patients) with use of the partially absorbable mesh were retrospectively reviewed. Data on patient demographics, hernia characteristics (side, subtype), date of operation, operating time, early and late postoperative complications as well as the recurrence rate were recorded over a 5-year period.

Results

The inguinal hernia was bilateral in 50 (50.0%) patients and indirect hernia was noted in 53 (53.0%) patients, while lipoma was evident in 17 (17.0%) cases. Median operating time was 45.0 min (range, 23.0 to 140.0 min). Overall, seroma occurred in 6 (6.0%) patients and was treated conservatively, while none of patients developed preperitoneal hematoma, infection or persistent chronic inguinal pain. Recurrence rate was 0.67% (1/150 operations) within a median 30.0 months (range, 2 to 60 months) of postoperative follow-up. Bilateral hernia was associated with significantly longer operating time compared to left or right unilateral hernia (median (min-max) 50.0 (34.0-140.0) vs. 40.0 (23-80) and 40.0 (25.0-130.0) min, p<0.01 and p<0.001, respectively). Operating time was positively correlated both with patient age (r=0.240, p=0.017) and BMI (r=0.205, p=0.044).

Conclusion

In conclusion, our findings indicate that laparoscopic TEP inguinal hernia repair with use of the partially absorbable meshes enables a favorable postoperative outcome with minimal early and late postoperative complications and 0.67% recurrence rate over a 5-year period.

Efficacy of Ivermectin, Chloroquine/Hydroxychloroquine, and Azithromycin in Managing COVID-19: A Systematic Review of Phase III Clinical Trials

Background: During the coronavirus disease (COVID)-19 pandemic several drugs were used to manage the patients mainly those with a severe phenotype. Potential drugs were used off-label and major concerns arose from their applicability to managing the health crisis highlighting the importance of clinical trials. In this context, we described the mechanisms of the three repurposed drugs [Ivermectin-antiparasitic drug, Chloroquine/Hydroxychloroquine-antimalarial drugs, and Azithromycin-antimicrobial drug]; and, based on this description, the study evaluated the clinical efficacy of those drugs published in clinical trials. The use of these drugs reflects the period of uncertainty that marked the beginning of the COVID-19 pandemic, which made them a possible treatment for COVID-19. Methods: In our review, we evaluated phase III randomized controlled clinical trials (RCTs) that analyzed the efficacy of these drugs published from the COVID-19 pandemic onset to 2023. We included eight RCTs published for Ivermectin, 11 RCTs for Chloroquine/Hydroxychloroquine, and three RCTs for Azithromycin. The research question (PICOT) accounted for P-hospitalized patients with confirmed or suspected COVID-19; I-use of oral or intravenous Ivermectin OR Chloroquine/Hydroxychloroquine OR Azithromycin; C-placebo or no placebo (standard of care); O-mortality OR hospitalization OR viral clearance OR need for mechanical ventilation OR clinical improvement; and T-phase III RCTs. Results: While studying these drugs' respective mechanisms of action, the reasons for which they were thought to be useful became apparent and are as follows: Ivermectin binds to insulin-like growth factor and prevents nuclear transportation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), therefore preventing cell entrance, induces apoptosis, and osmotic cell death and disrupts viral replication. Chloroquine/Hydroxychloroquine blocks the movement of SARS-CoV-2 from early endosomes to lysosomes inside the cell, also, this drug blocks the binding between SARS-CoV-2 and Angiotensin-Converting Enzyme (ACE)-2 inhibiting the interaction between the virus spike proteins and the cell membrane and this drug can also inhibit SARS-CoV-2 viral replication causing, ultimately, the reduction in viral infection as well as the potential to progression for a higher severity phenotype culminating with a higher chance of death. Azithromycin exerts a down-regulating effect on the inflammatory cascade, attenuating the excessive production of cytokines and inducing phagocytic activity, and acts interfering with the viral replication cycle. Ivermectin, when compared to standard care or placebo, did not reduce the disease severity, need for mechanical ventilation, need for intensive care unit, or in-hospital mortality. Only one study demonstrated that Ivermectin may improve viral clearance compared to placebo. Individuals who received Chloroquine/Hydroxychloroquine did not present a lower incidence of death, improved clinical status, or higher chance of respiratory deterioration compared to those who received usual care or placebo. Also, some studies demonstrated that Chloroquine/Hydroxychloroquine resulted in worse outcomes and side-effects included severe ones. Adding Azithromycin to a standard of care did not result in clinical improvement in hospitalized COVID-19 participants. In brief, COVID-19 was one of the deadliest pandemics in modern human history. Due to the potential health catastrophe caused by SARS-CoV-2, a global effort was made to evaluate treatments for COVID-19 to attenuate its impact on the human species. Unfortunately, several countries prematurely justified the emergency use of drugs that showed only in vitro effects against SARS-CoV-2, with a dearth of evidence supporting efficacy in humans. In this context, we reviewed the mechanisms of several drugs proposed to treat COVID-19, including Ivermectin, Chloroquine/Hydroxychloroquine, and Azithromycin, as well as the phase III clinical trials that evaluated the efficacy of these drugs for treating patients with this respiratory disease. Conclusions: As the main finding, although Ivermectin, Chloroquine/Hydroxychloroquine, and Azithromycin might have mechanistic effects against SARS-CoV-2 infection, most phase III clinical trials observed no treatment benefit in patients with COVID-19, underscoring the need for robust phase III clinical trials.

Abstracts accepted for the 2021-2023 French Orthopaedic and Traumatology Society meetings: Proportion of women submitters

BACKGROUND

Women are underrepresented in orthopaedic and trauma surgery worldwide, with proportions of 4%-17% across countries and 9.1% in France. The annual meeting of the French Society for Orthopaedic and Trauma Surgery (SOFCOT) provides opportunities for quantifying the representation of women, which has not yet been accurately evaluated. The objectives of this retrospective study were: 1) to evaluate the proportion of women relative to men who submitted abstracts accepted for presentation at annual SOFCOT meetings, 2) to analyse this proportion in each abstract category, and 3) to compare the professional profiles of submitting authors.

HYPOTHESIS

Among authors with abstracts accepted for presentation at annual SOFCOT meetings, only a minority were women.

METHODS

This retrospective study evaluated all abstracts accepted for presentation at the annual SOFCOT meetings held in 2021, 2022, and 2023. For each accepted abstract, the gender and professional profile of the submitting author were assessed. The female/male ratio was determined for each abstract category and professional profile for each of the three years.

RESULTS

The female/male ratio among authors of abstracts accepted in 2021, 2022, and 2023 was 161/923 (14.9% women), 128/541 (19.1%), and 120/550 (17.9%). The proportion of women was significantly less than the proportion of men for abstracts on the knee (41/333, 11% women (p = 0.0008)), hip (23/209, 9.9% (p = 0.002)), trauma (53 /358, 12,9% (p = 0.017)), and tumours (14/119, 10.5% (p = 0.04)). The proportion of women was also significantly smaller than the proportion of men among residents/fellows (154/491, 23.5% (p < 0.0001)), senior surgeons in non-university institutions (42/400, 11.5% (p < 0.0001)), and senior surgeons in university hospitals (23/164, 12.3% (p = 0.009)).

DISCUSSION

The representation of women compared to men remains low at annual SOFCOT meetings despite being greater than the overall representation of women among orthopaedic surgeons in France. These results highlight the appeal of research and growing interest for orthopaedic surgery among women. Scientific societies and surgical teams must continue to encourage this dynamic.

Epidemiological, clinical and microbiological characteristics of patients with biliary tract diseases with positive bile culture in a tertiary hospital

PURPOSE

The prevalence of biliary tract diseases, which are common gastrointestinal disorders, is steadily rising. If it progresses to sepsis or septic shock, it can endanger the patient's life. Therefore, it is crucial to promptly diagnose bacterial infection in individuals suffering from biliary diseases and comprehend the risk factors associated with infection. The objective of this study was to examine the types of bacteria present in the bile of patients with biliary tract diseases, assess any alterations in their susceptibility to antimicrobial agents, and identify the risk factors contributing to the development of infection in these patients.

PATIENTS AND METHODS

From June 2019 to November 2022, 317 patients of biliary tract diseases with positive bile culture were included in this hospital-based descriptive analysis. The hospital's computerized medical records were used to collect data on demographic information (including gender, age, and occupation), laboratory, and clinical findings, physical examination results, comorbidities, basic diseases, treatment history, complications, and in-hospital outcomes. The study followed the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) principles.

RESULTS

Of the 317 patients with positive biliary tract diseases, 247 had benign diseases and 70 had malignant diseases. Patients with benign disease experienced a higher prevalence of statistically significant symptoms such as abdominal pain (81.4% vs. 57.1%, P = 0.000), nausea (31.2% vs. 14.3%, P = 0.005), vomiting (30.0% vs. 12.9%, P = 0.004), and chills (10.9% vs. 2.9%, P = 0.039), while jaundice (12.6% vs. 37.1%, P = 0.000) was more common in patients with malignant disease. At the species level, Escherichia coli (105; 40.5%), Klebsiella pneumoniae (41; 15.8%), and Pseudomonas aeruginosa (30; 11.6%) were the most commonly found Gram-negative bacterial strains in biliary tract infection. Escherichia coli, Klebsiella pneumoniae, and Pseudomonas aeruginosa were most susceptible to tigecycline, ertapenem and ceftazidime/avibactam, respectively.

CONCLUSION

Gram-negative bacteria are the most commonly isolated biliary bacteria. Clinical doctors should pay attention to patients with malignant diseases with low hemoglobin, high total bilirubin and high alkaline phosphatase. Carbapenems, tigecycline, and minocycline are the recommended antibiotics for Enterobacteriaceae. In recent years, the proportion of enterococcus has gradually increased, and clinical attention should be paid to enterococcus infection. Linezolid and vancomycin were recommended for the treatment of Enterococci infections. Overall, this work can provide reference for clinical diagnosis, treatment and effective interventions.

Appropriate Use of Antibiotics in Acute Pancreatitis: A Scoping Review

BACKGROUND

While selective use of antibiotics for infected pancreatic necrosis (IPN) in acute pancreatitis (AP) is recommended, studies indicate a high rate of inadequate treatment.

METHODS

A search of PubMed, Scopus, and Cochrane databases was conducted, focusing on primary research and meta-analyses. Data were categorized based on core concepts, and a narrative synthesis was performed.

RESULTS

The search identified a total of 1016 publications. After evaluating 203 full texts and additional sources from the grey literature, 80 studies were included in the review. The answers obtained were: (1) Preventive treatment does not decrease the incidence of IPN or mortality. Given the risks of bacterial resistance and fungal infections, antibiotics should be reserved for highly suspected or confirmed IPN; (2) The diagnosis of IPN does not always require microbiological samples, as clinical suspicion or computed tomography signs can suffice. Early diagnosis and treatment may be improved by using biomarkers such as procalcitonin and novel microbiological methods; (3) When indicated, early initiation of antibiotics is a key determinant in reducing mortality associated with IPN; (4) Antibiotics with good penetration into pancreatic tissue covering Gram-negative and Gram-positive bacteria should be used. Routine antifungal therapy is not recommended; (5) The step-up approach, including antibiotics, is the standard for IPN management; (6) Antibiotic duration should be kept to a minimum and should be based on the quality of source control and patient condition.

CONCLUSIONS

Early antibiotic therapy is essential for the treatment of IPN, but prophylactic antibiotics are not recommended in AP. High-quality randomized controlled trials are required to better understand the role of antibiotics and antifungals in AP management.

Current Diagnosis and Treatment of Acute Pancreatitis in Korea: A Nationwide Survey

Background/Aims

Acute pancreatitis (AP) is a leading cause of emergency hospitalization. We present the current diagnostic and therapeutic status of AP as revealed by analysis of a large multicenter dataset.

Methods

The medical records of patients diagnosed with AP between 2018 and 2019 in 12 tertiary medical centers in Korea were retrospectively reviewed.

Results

In total, 676 patients were included, of whom 388 (57.4%) were male, and the mean age of all patients was 58.6 years. There were 355 (52.5%), 301 (44.5%), and 20 (3.0%) patients with mild, moderate, and severe AP, respectively, as assessed by the revised Atlanta classification. The most common etiologies of AP were biliary issues (41.6%) and alcohol consumption (24.6%), followed by hypertriglyceridemia (6.8%). The etiology was not identified in 111 (16.4%) patients at the time of initial admission. The overall mortality rate was 3.3%, increasing up to 45.0% among patients with severe AP. Notably, 70.0% (14/20) of patients with severe AP and 81.5% (154/189) of patients with systemic inflammatory response syndrome had received <4 L per day during the initial 24 hours of admission. Only 23.8% (67/281) of acute biliary pancreatitis patients underwent cholecystectomy during their initial admission. In total, 17.8% of patients experienced recurrent attacks during follow-up. However, none of the patients with acute biliary pancreatitis experienced recurrent attacks if they had undergone cholecystectomy during their initial admission.

Conclusions

This study provides insights into the current status of AP in Korea, including its etiology, severity, and management. Results reveal disparities between clinical guidelines and their practical implementation for AP treatment.

Management Options for Traumatic Posterior Sternoclavicular Joint Dislocation: A Narrative Review with a Single Institution's Experience

Background: Posterior sternoclavicular joint (SCJ) dislocations are rare events that can evolve into real emergencies due to the vital structures in the mediastinum. When closed reduction maneuvers fail, open SCJ reconstruction becomes mandatory, with literature proposing several stabilization techniques that either preserve or remove the SCJ's mobility. This study is a narrative review of the most recent literature regarding posterior trauma to the SCJ along with a single institution's experience of this pathology, managed either conservatively or surgically, with a figure-of-eight autologous semitendinosus graft in case of closed reduction failure. Methods: This article provides an overview of posterior traumatic SCJ dislocation, and it describes five cases of patients managed for traumatic posterior SCJ dislocation treated either conservatively or surgically with a figure-of-eight semitendinosus tendon autograft reinforced with high-strength suture tape. A comparison with the most recent literature is performed, focusing on biomechanics. Results: The demographics, the mechanism of injury, the management algorithm and the surgical strategy align with the most recent literature. Despite the final treatment, at one year of follow-up, the ROM was restored with full strength throughout the range of motion of the shoulder with no neurological deficits. The reduced joint successfully healed in imaging, and patients returned to their daily lives. The surgical site wounds and donor harvest sites were perfectly healed. Conclusions: Although recent recommendations for treating posterior traumatic SCJ dislocation have advanced, no universally accepted method of stabilization exists, and the surgical strategy is generally entrusted to the surgeon's experience. The literature still increasingly supports figure-of-eight ligament reconstruction with a biological or synthetic graft. This work further implements the literature by reporting good outcomes at follow-up.

Extended Lichtenstein Repair for an Additional Femoral Canal Hernia

The Lichtenstein procedure is one of the most performed surgeries worldwide. However, proper examination to exclude a femoral hernia is often not performed, resulting in a high number of missed hernias. For patients in whom a femoral hernia is suspected pre- or intraoperatively, we describe a novel surgical technique of a femoral extension to the classic Lichtenstein repair. We aim to investigate its safety and clinical outcome. Methods: The femoral-extended Lichtenstein is applied when a femoral hernia is suspected. The fascia transversalis is opened, the lacunar ligament incised, and the hernia reduced. A self-gripping mesh covers the femoral orifice equally on all sides. In a prospective single-center study, we compared 50 consecutive femoral-extended to 50 classic Lichtenstein repairs, evaluating operative time, patient-reported pain (intensity, duration), and recurrence. Results: The technique seems feasible and safe. Apart from 3 min additional surgical time, no difference in pain scoring or hernia recurrence was observed between both groups. Conclusions: We successfully introduced a femoral-extended Lichtenstein repair for patients with suspected femoral herniation.

ASA-score is associated with 90-day mortality after complicated mild traumatic brain injury - a retrospective cohort study

PURPOSE

This study explores the association of the American Society of Anesthesiologists (ASA) score with 90-day mortality in complicated mild traumatic brain injury (mTBI) patients, and in trauma patients without a TBI.

METHODS

This retrospective study was conducted using a cohort of trauma patients treated at a level III trauma center in Stockholm, Sweden from January to December 2019. The primary endpoint was 90-day mortality. The population was identified using the Swedish Trauma registry. The Trauma and Injury Severity Score (TRISS) was used to estimate the likelihood of survival. Trauma patients without TBI (NTBI) were used for comparison. Data analysis was conducted using R software, and statistical analysis included univariate and multivariate logistic regression.

RESULTS

A total of 244 TBI patients and 579 NTBI patients were included, with a 90-day mortality of 8.2% (n = 20) and 5.4% (n = 21), respectively. Deceased patients in both cohorts were generally older, with greater comorbidities and higher injury severity. Complicated mTBI constituted 97.5% of the TBI group. Age and an ASA score of 3 or higher were independently associated with increased mortality risk in the TBI group, with odds ratios of 1.04 (95% 1.00-1.09) and 3.44 (95% CI 1.10-13.41), respectively. Among NTBI patients, only age remained a significant mortality predictor. TRISS demonstrated limited predictive utility across both cohorts, yet a significant discrepancy was observed between the outcome groups within the NTBI cohort.

CONCLUSION

This retrospective cohort study highlights a significant association between ASA score and 90-day mortality in elderly patients with complicated mTBI, something that could not be observed in comparative NTBI cohort. These findings suggest the benefit of incorporating ASA score into prognostic models to enhance the accuracy of outcome prediction models in these populations, though further research is warranted.

Laparoscopic transabdominal preperitoneal repair for a patient with Laugier's and inguinal hernia

BACKGROUND

Laugier's hernia is a very rare atypical femoral hernia and is challenging to diagnose preoperatively. Herein, we report a rare case of inguinal and Laugier's hernias treated with laparoscopic transabdominal preperitoneal repair.

CASE PRESENTATION

A 63-year-old man was admitted to our hospital with right groin swelling for 4 years. Computed tomography revealed an indirect inguinal hernia with protrusion of the small intestine. The preoperative diagnosis was right indirect inguinal hernia; Laugier's hernia was unknown. The patient underwent laparoscopic transabdominal preperitoneal repair. During the surgery, part of the perivesical adipose tissue penetrated the lacunar ligament. It was located medial to the typical site of a femoral hernia. Thus, Laugier's hernia was diagnosed. Finally, laparoscopic transabdominal preperitoneal repair was performed for Laugier's hernia and inguinal hernia. The postoperative course was good, without recurrence.

CONCLUSIONS

To our knowledge, this is the first reported case of inguinal and Laugier's hernia treated with laparoscopic transabdominal preperitoneal repair. Surgeons should be mindful that inguinal hernias can occur concurrently with other types of hernias, such as femoral hernias, including atypical variants like Laugier's hernia. Additionally, they should actively consider laparoscopic approaches such as transabdominal preperitoneal for femoral hernias. These approaches are beneficial for precise diagnosis, confirming the presence of other hernias, and simultaneously treating all coexisting inguinal hernias.

Diastasis Recti Abdominis: A Practical and Effective Width-Length Classification Based on Ultrasound Measurements and its Clinical Validation

OBJECTIVES

This study aimed to establish a simple and practical classification to guide the clinical treatment of diastasis recti abdominis (DRA) based on ultrasound characteristics with different severities of DRA, and to verify its clinical utility.

METHODS

We retrospectively enrolled 301 DRA patients as pilot cohort and divided into Conservative Treatment Group and Surgical Group according to clinical outcomes. A new Width-Length classification was summarized based on ultrasound measurements of the width and length of midline separation. Then, 100 DRA patients were enrolled prospectively as validation cohort, and diagnostic performance was evaluated by clinical treatment.

RESULTS

The Width-Length classification in pilot cohort was as follows: Type 1 (n = 108), open only at M3; Type 2 (n = 63), open at M3 and either M2 or M4 (inter-rectus distance at M3 <47 mm); Type 3 (n = 44), open at M3 and either M2 or M4 (inter-rectus distance at M3 ≥47 mm); Type 4 (n = 74), open at M3, along with other two sites of M1, M2, M4, or M5; Type 5 (n = 12), open at M2, M3, and M4, along with M1 or M5, or both. DRA patients in Type 1-2 were recommended for conservative treatment, and in Type 3-5 were recommended for surgical treatment (all P < .05). In the validation cohort, the accuracy of Width-Length classification in determining treatment strategy was 86.0%.

CONCLUSIONS

This study proposes a Width-Length classification based on the width and length of midline separation on ultrasound, which was validated to be simple, practical and effective in guiding DRA treatment.
