Wound Healing Following Open Groin Hernia Surgery: The Impact of Comorbidity

Totally extraperitoneal repair of groin hernia in liver transplant patients: a case series study (TOHER)

PURPOSE

The present study aims to describe the feasibility and the postoperative results of groin hernia repair in liver transplant patients using a totally extra-peritoneal (TEP) repair approach.

METHODS

From May 2022 to March 2023, liver transplant patients with groin hernia underwent TEP groin hernia repair, by the single common senior experimented surgeon. Background information, intraoperative findings, postoperative complications, postoperative pain, health, and well-being were registered.

RESULTS

Thirteen TEP approach groin hernioplasties were performed in 10 patients, completing the procedure in all cases without the need for conversion either to open or transabdominal preperitoneal approaches. 70% of surgical explorations revealed multiple hernia defects: lateral hernias in all patients, medial defects in 62%, and femoral defects in 30.8%. Median hospital stay was 1 day [range (0.3)], with 30% treated as outpatients. Post-surgical complications occurred in 30% of cases: 1 hematoma and 2 seromas. Postoperative pain and physical functioning scored 100 (IQR 44) and 90 (IQR 15), respectively.

CONCLUSION

TEP groin hernioplasty is safe and feasible for liver transplant patients, with low complication rates, short hospital stays, and a significant proportion treated as outpatients. The posterior approach allows comprehensive repair of myopectineal defects, crucial due to associated hernial defects.

The impact of compensated and decompensated cirrhosis on the postoperative outcomes of patients undergoing hernia repair: a propensity score-matched analysis of 2011-2017 US hospital database

BACKGROUND AND AIMS

Since there is clinical overlap between populations with cirrhosis and those who require hernia repair (i.e. due to stretching of abdominal walls), we systematically evaluate the effects of cirrhosis on post-hernia repair outcomes.

METHODS

2011-2017 National Inpatient Sample was used to identify patients who underwent hernia repair (included: inguinal, umbilical, and other abdominal hernia repairs). The population was stratified into those with compensated cirrhosis (CC), decompensated cirrhosis (DC), and no cirrhosis; hepatic decompensation was defined as those with portal hypertension, ascites, and varices. The propensity score was used to match the no-cirrhosis controls to CC and DC using the 1:1 nearest neighbor mechanism. Endpoints included mortality, length of stay, costs, and complications.

RESULTS

Postmatch, there were 392/446 CC/DC with equal number controls in those undergoing inguinal hernia repair, 714/1652 CC/DC with equal number controls in those undergoing umbilical hernia repair, and 784/702 CC/DC. In multivariate, for inguinal repair, there was no difference in mortality [CC vs. no-cirrhosis aOR 2.61, 95% confidence interval (CI) 0.50-13.52; DC vs. no-cirrhosis: aOR 1.75, 95% CI 0.84-3.63]. For umbilical repair, there was no difference in mortality for CC vs. no-cirrhosis: aOR 0.94, 95% CI 0.36-2.42); however, DC had higher mortality (aOR 2.86, 95% CI 1.76-4.63) when comparing DC vs. no-cirrhosis. For other abdominal repairs, there was no difference in mortality for CC vs. no-cirrhosis (aOR 1.10, 95% CI 0.54-2.23); however, DC had higher mortality (P < 0.001, aOR 2.58, 95% CI 1.49-4.46) when comparing DC vs. no-cirrhosis.

CONCLUSION

This study demonstrates that the presence of DC affects postoperative survival in patients undergoing umbilical or other abdominal hernia repair surgery.

Perioperative outcome in groin hernia repair: what are the most important influencing factors?

INTRODUCTION

Using registry analyses, a large number of influencing factors on the perioperative outcome of groin hernia repair has been identified. The interactions between several influencing factors and differences in the influencing value have to date been inadequately investigated.

METHODS

This retrospective analysis of prospectively collected data from the Herniamed Registry included all fully documented cases with minimum age of 16 years and groin hernia repair. Patients were assigned to the risk groups unilateral, bilateral, recurrent and emergency groin hernia repair. Multivariable analysis was performed to investigate the influence of confirmatory defined patient- and procedure-related characteristics on the outcome parameters intraoperative, postoperative general and postoperative surgical complications, complication-related reoperation and total perioperative complications.

RESULTS

A highly significantly unfavorable association with the total perioperative complication rate was identified for emergency groin hernia repair, scrotal hernia, anticoagulant medication and coagulopathy. A significantly unfavorable relation with the total perioperative complication rate was found for recurrence procedure, bilateral repair, high age, ASA score III/IV, femoral hernia, antithrombotic medication, smoking, COPD and corticosteroid medication. A significantly favorable correlation with the total perioperative complication rate was observed for the laparo-endoscopic techniques, smaller defects, female gender, normal weight and medial hernia.

CONCLUSION

Both the number of potential influencing factors and their influencing value on the perioperative outcome should be considered when estimating the individual risk of a patient with groin hernia repair.

Perioperative Evaluation and Management of Patients With Cirrhosis: Risk Assessment, Surgical Outcomes, and Future Directions

BACKGROUND AND AIMS

Patients with cirrhosis are at increased risk of perioperative morbidity and mortality. We provide a narrative review of the available data regarding perioperative morbidity and mortality, risk assessment, and management of patients with cirrhosis undergoing non-hepatic surgical procedures.

METHODS

We conducted a comprehensive review of the literature from 1998-2018 and identified 87 studies reporting perioperative outcomes in patients with cirrhosis. We extracted elements of study design and perioperative mortality by surgical procedure, Child-Turcotte-Pugh (CTP) class and Model for End-stage Liver Disease (MELD) score reported in these 87 studies to support our narrative review.

RESULTS

Overall, perioperative mortality is 2-10 times higher in patients with cirrhosis compared to patients without cirrhosis, depending on the severity of liver dysfunction. For elective procedures, patients with compensated cirrhosis (CTP class A, or MELD <10) have minimal increase in operative mortality. CTP class C patients (or MELD >15) are at high risk for mortality; liver transplantation or alternatives to surgery should be considered. Very little data exist to guide perioperative management of patients with cirrhosis, so most recommendations are based on case series and expert opinion. Existing risk calculators are inadequate.

CONCLUSIONS

Severity of liver dysfunction, medical comorbidities and the type and complexity of surgery, including whether it is elective versus emergent, are all determinants of perioperative mortality and morbidity in patients with cirrhosis. There are major limitations to the existing clinical research on risk assessment and perioperative management that warrant further investigation.

Open inguinal hernia repair outcomes in liver transplant recipients versus patients with cirrhosis

PURPOSE

Patients with liver cirrhosis (LC) are at an increased risk for postoperative complications after open inguinal hernia repair (OIHR). It is possible that orthotopic liver transplant (OLT) recipients may have better outcomes, given reversal of liver failure pathophysiology. Therefore, we sought to compare mortality risk, complications, length of stay (LOS), and cost associated with OIHR in OLT recipients versus LC.

METHODS

From the National Inpatient Sample (NIS), using ICD-9 codes, we found 83 OLT recipients and 764 patients with LC who underwent OIHR between 2002 and 2014. We used logistic, negative binomial, and multiple linear regression models to compare peri-operative mortality risk, postoperative complications, and LOS, and cost associated with OIHR in OLT recipients versus LC patients. Models were adjusted for patient demographic and clinical characteristics, and hospital factors.

RESULTS

OLT recipients were younger (58 vs 61, p = 0.02), more likely to be privately insured (42.0% vs 24.6%, p = 0.006), less likely to have ascites at time of surgery (5.1% vs 18.9%, p = 0.003), and have surgery at large (84.3% vs 65.2%, p = 0.01) and teaching hospitals (84.2% vs 47.9%, p < 0.001). There were no mortalities among OLT recipients, but 19 (2.5%) deaths among LC patients. OLT recipients had a similar risk of overall complications (adjusted odds ratio aOR = 0.71 1.30 2.41) and hospital-associated costs (adjusted cost ratio = 0.71 0.88 1.09). However, LOS was significantly different with OLT recipients having shorter LOS (adjusted LOS ratio = 0.56 0.70 0.89).

CONCLUSION

Delaying OIHR in patients with LC until after OLT decreases LOS and may carry decreased mortality.

Assessment of postoperative risk of complications on inguinal hernioplasty and its relation to risk factors

INTRODUCTION Abdominal wall hernias are a highly prevalent pathology, considering that 55 percent of the world population is affected by this disease at some point in their lives. As a large part of these patients present comorbidities, it is important to correlate the incidence of complications with the presence of previous pathologies. OBJECTIVES To evaluate whether the presence of comorbidities in patients submitted to inguinal hernioplasty increases the risk of acute and chronic complications in the postoperative period, as well as to explain which of these prior diseases present a greater association with the incidence of complications. METHODS This is a cross-sectional descriptive study carried out through the retrospective analysis of 313 medical records of patients submitted to open inguinal hernioplasty surgery between March and June 2017 at the General Surgery Service of the Cruz Vermelha Hospital - Paraná Branch, located in the City of Curitiba, state of Paraná, Brasil. RESULTS Of the 313 cases studied, the most prevalent comorbidities were: 107 patients with hypertension (34.19%), 52 smokers (16.61%), 30 cases with diabetes (9.58%), 14 with hypothyroidism (4,47%) and 10 with COPD (3.19%). Regarding the total of the sample evaluated, 130 patients (41.53%) did not present any comorbidity. When evaluating the complications, there were 49 cases (15.65%) of complications in the early postoperative period and 9 cases (2.88%) of chronic complications. The comorbidities that presented significant statistical influence (p <0.05) on the incidence of acute complications were hypertension (p = 0.02927) and smoking (p = 0.03196). CONCLUSION It is important to note the presence of acute postoperative complications of inguinal hernioplasty in patients who have hypertension or smoke, high prevalence diseases.

Fournier's Gangrene in Females: Presentation and Management at a Tertiary Center

OBJECTIVE

To report and compare presentation and management of Fournier's Gangrene (FG) in female vs male patients at a single tertiary care center.

METHODS

Patient demographics, clinical characteristics, treatments and outcomes were summarized and compared between males and females who were treated for FG from 2011 to 2018 at a single institution.

RESULTS

Of the 143 patients treated for FG at our institution, 33 (23%) were female. Female patients were predominantly white (82%), with a median (IQR) age of 55 (46, 59). Median female boby mass index (BMI) was 42.1 (32, 50.4). Female patients' wound cultures were polymicrobial mix of gram positive and gram negative organisms. Median number of debridements for females was 2 (1,3). The most common anatomic region of gangrene involvement in females was labia (76%) followed by perineum (55%) and gluteus/buttocks (42%). Mortality rate during initial admission was 6% for females. Female patients had a higher median BMI than males (42.1 vs 33.7 respectively; P = .003). FG severity index, length of hospital stay, number of debridements, and wound cultures were comparable to males. The surgical team managing initial debridements differed with females managed primarily by general surgery and males primarily by urology. Mortality rate was comparable to men (6% vs 7%, P >.05).

CONCLUSION

Female patients with FG have greater BMI but similar clinical presentation, microbiologic characteristics and mortality rate compared to men. Urologists have little involvement during initial management for females at our institution.

Factors associated with complex surgical wounds in breast and abdomen: a case-control observational study

OBJECTIVE

to identify factors associated with complex surgical wounds in the breasts and abdomen in outpatients.

METHOD

observational case-control study involving 327 patients, distributed into 160 cases (complex surgical wound) and 167 controls (simple surgical wound). Data were extracted from the medical records and a binary logistic regression model was used for analysis, considering a significance level of 5%.

RESULTS

the factors associated with greater chance of occurrence of complex surgical wound were 18 to 59 years of age (p = 0.003), schooling < 8 years (p = 0.049), radiotherapy (p < 0.001), hysterectomy (p = 0.003), glycemia (≤ 99 mg/dL) and arterial hypertension (p = 0.033), while quadrantectomy (p = 0.025) served as a protective factor.

CONCLUSION

radiotherapy was the most significant factor for surgical wound complications. Glycemic alteration was an unexpected result and shows the need for further studies related to this topic.

Is Anterior Approach Alone With Mesh Appropriate for Incarcerated Groin Hernias?: A Retrospective Analysis

This study evaluates whether an extra incision is needed in addition to the standard inguinal incision for the surgery of incarcerated groin hernias. Patients with groin hernias present to an emergency unit when their hernia incarcerates or strangulates. The classical approach to such presentations is open surgery, and a second incision is sometimes needed to resect the strangulated organ. This is a retrospective study enrolling 218 patients treated for incarcerated groin hernias at a state hospital between 2006 and 2010. Data collected were demographic data, type and location of hernia, type of surgery and anesthesia, type of incision, need for resection, and preoperative complications. A total of 37.9% of female and 13.2% of male patients had resection of an abdominal organ. Of patients with incarcerated groin hernias, 20% (n = 43) had resection. Omentum was the most commonly resected organ (n = 19; 8.8%), followed by small intestine (n = 11; 5.1%), bladder, appendix, lymphadenopathy, and preperitoneal fat (each n = 3 and 1.4%). Of 218 patients, 10 (4.58%) needed a secondary incision for hernia reduction. All of these patients had their surgery with one of the anterior approach techniques. There was no statistically significant difference (P = 0.4) in need for secondary incision between the anterior and posterior approach techniques. In recent years, posterior approach for incarcerated groin hernias was deemed advantageous because it did not necessitate an additional incision for definitive surgery. Our study showed that in the treatment of incarcerated inguinal hernia, Lichtenstein repair is also a safe and easy alternative, without the need for a second incision.

Risk factors for postoperative complications in total thyroidectomy: A retrospective, risk-adjusted analysis from the National Surgical Quality Improvement Program

Thyroid cancer incidence is increasing, and with it, an increase in total thyroidectomy. There are limited studies comparing outcomes in total thyroidectomy performed in the inpatient versus outpatient setting.The objective of this study was to perform a comparative analysis of risk factors and outcomes of postoperative morbidity and mortality in total thyroidectomy performed as an inpatient versus outpatient surgery.Retrospective cohort study of data from the 2005 to 2014 multi-institutional, risk-adjusted American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database. A multivariate regression model with corresponding odds ratios and 95% confidence intervals was used to determine 30-day morbidity and mortality after total thyroidectomies, and also risk factors of postoperative outcomes.From 2005 to 2014, 40,025 total thyroidectomies were performed (48.5% inpatient, 51.5% outpatient). The 30-day complication rate for all total thyroidectomies was 7.74%. Multivariate logistic regression analysis was performed to control for potential confounding variables. Preoperative factors that affected complications rates for inpatient thyroidectomies included: age ≥70, non-Caucasian race, dependent functional status, history of congestive heart failure, smoking history, bleeding disorder, wound infection, and preoperative sepsis (P < 0.05). In addition, preoperative factors affecting complications in thyroidectomy performed as an outpatient surgery included malignant thyroid pathology (P  0.05).We identified a subset of preoperative conditions that affect risk of complications after total thyroidectomy. Recommendations for patient selection for outpatient total thyroidectomies should be modified to account for pre-existing conditions that increase the risk of postoperative morbidity.

Data and outcome of inguinal hernia repair in hernia registers - a review of the literature

Register-based observational studies in inguinal hernia repair deliver real-world data from very large patient populations and give answers to important clinical questions never evaluated in randomized controlled trials. Data from hernia registers can provide evidence of effectiveness of therapies in the general population. Hernia registers with high case load have existed in Sweden since 1992, in Denmark since 1998, and in Germany/Austria/Switzerland since 2009. In this review, the most important findings of register-based observational studies in inguinal hernia repair are presented. After an intensive literature search, 85 articles are relevant for this review. Numerous findings from these register-based studies have been incorporated into the various guidelines on inguinal hernia repair. These highlight the particular importance of hernia registers in answering key scientific and clinical questions in hernia surgery. The myriad of surgical techniques described – spanning more than 100 and with ongoing new additions – as well as the large number of associated medical devices call for, more than in other surgical disciplines, meticulous documentation of the methods used for the treatment of inguinal hernias.
