Laparoscopic versus open hernia repair: outcomes and sociodemographic utilization results from the nationwide inpatient sample

Laparoscopic ventral/incisional hernia repair: updated Consensus Development Conference based guidelines [corrected]

BACKGROUND

The Executive board of the Italian Society for Endoscopic Surgery (SICE) promoted an update of the first evidence-based Italian Consensus Conference Guidelines 2010 because a large amount of literature has been published in the last 4 years about the topics examined and new relevant issues.

METHODS

The scientific committee selected the topics to be addressed: indications to surgical treatment including special conditions (obesity, cirrhosis, diastasis recti abdominis, acute presentation); safety and outcome of intraperitoneal meshes (synthetic and biologic); fixing devices (absorbable/non-absorbable); abdominal border and parastomal hernia; intraoperative and perioperative complications; and recurrent ventral/incisional hernia. All the recommendations are the result of a careful and complete literature review examined with autonomous judgment by the entire panel. The process was supervised by experts in methodology and epidemiology from the most qualified Italian institution. Two external reviewers were designed by the EAES and EHS to guarantee the most objective, transparent, and reliable work. The Oxford hierarchy (OCEBM Levels of Evidence Working Group*. "The Oxford 2011 Levels of Evidence") was used by the panel to grade clinical outcomes according to levels of evidence. The recommendations were based on the grading system suggested by the GRADE working group.

RESULTS AND CONCLUSIONS

The availability of recent level 1 evidence (a meta-analysis of 10 RCTs) allowed to recommend that not only laparoscopic repair is an acceptable alternative to the open repair, but also it is advantageous in terms of shorter hospital stay and wound infection rate. This conclusion appears to be extremely relevant in a clinical setting. Indications about specific conditions could also be issued: laparoscopy is recommended for the treatment of recurrent ventral hernias and obese patients, while it is a potential option for compensated cirrhotic and childbearing-age female patients. Many relevant and controversial topics were thoroughly examined by this consensus conference for the first time. Among them are the issue of safety of the intraperitoneal mesh placement, traditionally considered a major drawback of the laparoscopic technique, the role for the biologic meshes, and various aspects of the laparoscopic approach for particular locations of the defect such as the abdominal border or parastomal hernias.

Raising the quality of hernia care: Is there a need?

INTRODUCTION

With a focus on raising the quality of hernia care through creation of educational programs, SAGES formed the Hernia Task Force (HTF). This study used needs assessment survey to target opportunities for improving surgical training and thus patient outcomes and experience.

METHODS

This qualitative study included structured interviews and online surveys of key stakeholders: HTF members, surgeons, nurses, patients, hospital administrators, healthcare payers and medical suppliers. Questions included perceptions of recurrence and complication rates, their etiologies, perceived deficits in current hernia care and the most effective and training modalities.

RESULTS

A total of 841 participants included 665 surgeons, 66 patient care team members, 12 hospital administrators and 14 medical supply providers. Assessment of technical approach revealed that nearly 26 % of surgeons apply the same, limited range of techniques to all patients without evaluation of patient-specific factors. The majority (71 %) of surgeon respondents related hernia recurrence rates nearing 25 % or more. HTF members implicated surgeon factors (deficits in knowledge/technique, etc.) as primary determinants of recurrences, whereas nurses, medical supply providers and hospital administrators implicated patient health factors. Surgeons preferred attending conferences (82 %), reading periodicals/publications (71 %), watching videos (59 %) and communicating with peers (57 %) for learning and skill improvement. Topics of the greatest interest were advanced techniques for hernia repairs (71 %), preoperative and intraoperative decision making (56 %) and patient outcomes (64 %). Eighty-six percent of nurses felt that there was room for improvement in hernia patient safety and teamwork in the OR. Only 24 % believed that the patients had adequate preoperative education.

CONCLUSIONS

Major reported deficits in hernia care include: lack of standardization in training and care, "one size fits all" technical approach and inadequate patient follow-up/outcome measures. There is a need for a comprehensive, flexible and tailored educational program to equip surgeons and their teams to raise the quality of hernia care and bring greater value to their patients.

Laparoscopic versus open ventral hernia repair: longitudinal outcomes and cost analysis using statewide claims data

BACKGROUND

There is still considerable debate regarding the best operative approach to ventral hernia repair. Using two large statewide databases, this study sought to evaluate the longitudinal outcomes and associated costs of laparoscopic and open ventral hernia repair.

METHODS

All patients undergoing elective ventral hernia repair from 2007-2011 were identified from inpatient discharge data from California and New York. In-hospital morbidity, in-hospital mortality, incidence of readmission, and incidence of revisional ventral hernia repair were evaluated as a function of surgical technique. The associated costs of medical care for laparoscopic versus open ventral hernia repair were evaluate for both the index procedure and all subsequent admissions and procedures within the study period.

RESULTS

A total of 13,567 patients underwent elective ventral hernia repair with mesh; 9228 (69%) underwent OVHR and 4339 (31%) underwent LVHR. At time of the index procedure, LVHR was associated with a lower incidence of reoperation (OR 0.29, CI 0.12-0.58, p = 0.001), wound disruption (OR 0.35, CI 0.16-0.78, p = 0.01), wound infection (OR 0.50, CI 0.25-0.70, p < 0.001), blood transfusion (OR 0.47, CI 0.36-0.61, p < 0.001), ARDS (OR 0.74, CI 0.54-0.99, p < 0.05), and total index visit complications (OR 0.72, CI 0.64-0.80, p < 0.001). LVHR was associated with significantly fewer readmissions (OR 0.81, CI 0.75-0.88, p < 0.001) and a lower risk for revisional VHR (OR 0.75, CI 0.64-0.88, p < 0.001). LVHR was associated with lower total costs at 1 year ($3451, CI 1892-5011, p < 0.001).

CONCLUSIONS

Open ventral hernia repair was associated with a higher incidence of perioperative complications, postoperative readmissions and need for revisional hernia repair when compared to laparoscopic ventral hernia repair, even when controlling for patient sociodemographics. In congruence, open ventral hernia repair was associated with higher costs for both the index hernia repair and tallied over the length of follow-up for readmissions and revisional hernia repair.

Inpatient outcomes after elective versus nonelective ventral hernia repair

BACKGROUND

Patients who present emergently with hernia-related concerns may experience increased morbidity with repair when compared with those repaired electively. We sought to characterize the outcomes of patients who undergo elective and nonelective ventral hernia (VH) repair using a large population-based data set.

MATERIALS AND METHODS

The Nationwide Inpatient Sample was queried for primary International Classification of Diseases, Ninth Revision codes associated with VH repair (years 2008-2011). Outcomes were inhospital mortality and the occurrence of a preidentified complication. Multivariable analysis was performed to determine the risk factors for complications and mortality after both elective and nonelective VH repair.

RESULTS

We identified 74,151 VH repairs performed during the study interval. Of these procedures, 67.3% were elective and 21.6% were performed laparoscopically. Nonelective repair was associated with a significantly higher rate of morbidity (22.5% versus 18.8%, P < 0.01) and mortality (1.8% versus 0.52, P < 0.01) than elective repair. Elective repairs were more likely to occur in younger patients, Caucasians, and were more likely to be performed laparoscopically. Logistic modeling revealed that female gender, Caucasian race, elective case status, and laparoscopic approach were independently associated with a lower probability of complications and mortality. Minority status and Medicaid payer status were associated with increased probability of nonelective admission.

CONCLUSIONS

Patients undergoing elective VH repair in the United States tend to be younger, Caucasian, and more likely to have a laparoscopic repair. Nonelective VH is associated with a substantial increase in morbidity and mortality. We recommend that patients consider elective repair of VHs because of the increased morbidity and mortality associated with nonelective repair.

Laparoscopic ventral hernia repair with primary closure versus no primary closure of the defect: potential benefits of the robotic technology

BACKGROUND

Some authors recommend primary closure of the defect before placement of the mesh. The purpose of this study is to compare laparoscopic ventral hernia repair (LVHR) without primary closure of the defect (NPCD) versus LVHR with primary closure of the defect (PCD).

METHODS

A retrospective review of 134 LVHR was performed. Each group included 67 cases. For the PCD group the robotic platform was used.

RESULTS

Groups were similar in terms of demographics and comorbidities. For NPCD and PCD groups mean surgical time was 87.9±53.1 and 107.6±33.9 minutes (p = 0.012); conversion to open surgery was seen in 3(4.5%) and 1(1.5%) (p = 0.310); complications were 7(10.4%) and 2(3%) (p = 0.084); and finally, recurrences were seen in 5(7.5%) and 1(1.5%) (p = 0.095).

CONCLUSIONS

PCD has longer surgical time, however, a tendency in terms of complications and recurrences was found favoring the PCD group. The robotic assistance is a good alternative when primary closure of the defect is attempted.

Laparoscopic transabdominal inguinal hernia repair in community hospital settings: a general surgeon's last 10 years experience

Numerous studies have documented the laparoscopic TransAbdominal Pre-Peritoneal (TAPP) approach as an excellent choice for inguinal hernia repair, especially with an experienced surgeon. A cohort population of patients who underwent TAPP laparoscopic surgery for inguinal hernias over the last 10 years, with follow-up, were evaluated, focusing on the feasibility, safety and benefits of this procedure in a community hospital setting.

MATERIALS AND METHODS

A total of 533 patients underwent TAPP for inguinal hernias between January 2003 and March 2013 in two community hospitals in the Northeast of Italy-"Civil Hospital" in Vittorio Veneto (TV) and "Civil Hospital" in Adria (RO).

RESULTS

The total number of hernias treated was 1,000. The overall mean operative time was 43.50 min (±13.2). All but three of the procedures were done on a day surgery basis. There were no conversions to open repair or deaths in our series. We had two cases of small bowel obstruction and eight relapses (0.8 %) in our series. The mean follow-up was 59.4 months (±5.6; range 3-120). No patients reported severe pain at 10 days, 21 patients (3.9 %) reported mild pain at 3-month follow-up. Over 90 % of the patients had a return of physical work capacity within 2 weeks, the remaining within 30 days. All patients were completely satisfied (numerical rating scale 10/10) 3 months after the operation.

CONCLUSIONS

The analysis of the short- and long-term post-operative outcomes of our experience enabled us to conclude that in an appropriate setting, TAPP is feasible, effective, safe and beneficial for patients. It should be incorporated into general surgeons' expertise and selectively used for the management of patients with hernias, as long as adequate training is obtained and appropriate preparation performed.

Impact of the Establishment of a Specialty Hernia Referral Center

Background. Creating a surgical specialty referral center requires a strong interest, expertise, and a market demand in that particular field, as well as some form of promotion. In 2004, we established a tertiary hernia referral center. Our goal in this study was to examine its impact on institutional volume and economics. Materials and methods. The database of all hernia repairs (2004-2011) was reviewed comparing hernia repair type and volume and center financial performance. The ventral hernia repair (VHR) patient subset was further analyzed with particular attention paid to previous repairs, comorbidities, referral patterns, and the concomitant involvement of plastic surgery. Results. From 2004 to 2011, 4927 hernia repairs were performed: 39.3% inguinal, 35.5% ventral or incisional, 16.2% umbilical, 5.8% diaphragmatic, 1.6% femoral, and 1.5% other. Annual billing increased yearly from 7% to 85% and averaged 37% per year. Comparing 2004 with 2011, procedural volume increased 234%, and billing increased 713%. During that period, there was a 2.5-fold increase in open VHRs, and plastic surgeon involvement increased almost 8-fold, ( P = .004). In 2005, 51 VHR patients had a previous repair, 27.0% with mesh, versus 114 previous VHR in 2011, 58.3% with mesh ( P < .0001). For VHR, in-state referrals from 2004 to 2011 increased 340% while out-of-state referrals jumped 580%. In 2011, 21% of all patients had more than 4 comorbidities, significantly increased from 2004 ( P = .02). Conclusion. The establishment of a tertiary, regional referral center for hernia repair has led to a substantial increase in surgical volume, complexity, referral geography, and financial benefit to the institution.

Outcomes of pancreatic debridement in acute pancreatitis: analysis of the nationwide inpatient sample from 1998 to 2010

BACKGROUND

The objective of this study was to perform a national review of patients with acute pancreatitis (AP) who undergo pancreatic debridement (PD) to evaluate for risk factors of in-hospital mortality.

METHODS

The Nationwide Inpatient Sample was used to identify patients with AP who underwent PD between 1998 and 2010. Risk factors for in-hospital mortality were assessed with multivariate logistic regression.

RESULTS

From 1998 to 2010, there were 585,978 nonelective admissions with AP, of which 1,783 (.3%) underwent PD. From 1998 to 2010, the incidence of PD decreased from .44% to .25% (P < .01) and PD in-hospital mortality decreased from 29.0% to 15% (P < .05). Of patients undergoing PD, independent factors associated with increased odds of mortality were increased age (odds ratio [OR] 1.04, confidence interval [CI] 1.03 to 1.05; P < .01), sepsis with organ failure (OR 1.76, CI 1.24 to 2.51; P < .01), peptic ulcer disease (OR 1.83, CI 1.02 to 3.30; P < .05), liver disease (OR 2.27, CI 1.36 to 3.78; P < .01), and renal insufficiency (OR 1.78, CI 1.14 to 2.78; P < .05).

CONCLUSIONS

The incidence and operative mortality of PD have decreased significantly over the last decade in the United States with higher odds of dying in patients who are older, with chronic liver, renal, or ulcer disease, and higher rates of sepsis with organ failure.

The first nationwide evaluation of robotic general surgery: a regionalized, small but safe start

BACKGROUND

The purpose of this study was to evaluate the outcomes of the most commonly performed robotic-assisted general surgery (RAGS) procedures in a nationwide database and compare them with their laparoscopic counterparts.

METHODS

The Nationwide Inpatient Sample was queried from October 2008 to December 2010 for patients undergoing elective, abdominal RAGS procedures. The two most common, robotic-assisted fundoplication (RF) and gastroenterostomy without gastrectomy (RG), were individually compared with the laparoscopic counterparts (LF and LG, respectively).

RESULTS

During the study, 297,335 patients underwent abdominal general surgery procedures, in which 1,809 (0.6 %) utilized robotic-assistance. From 2009 to 2010, the incidence of RAGS nearly doubled from 573 to 1128 cases. The top five RAGS procedures by frequency were LG, LF, laparoscopic lysis of adhesions, other anterior resection of rectum, and laparoscopic sigmoidectomy. Eight of the top ten RAGS were colorectal or foregut operations. RG was performed in 282 patients (0.9 %) and LG in 29,677 patients (99.1 %). When comparing RG with LG there was no difference in age, gender, race, Charlson comorbidity index (CCI), postoperative complications, or mortality; however, length of stay (LOS) was longer in RG (2.5 ± 2.4 vs. 2.2 ± 1.5 days; p < 0.0001). Total cost for RG was substantially higher ($60,837 ± 28,887 vs. $42,743 ± 23,366; p < 0.0001), and more often performed at teaching hospitals (87.2 vs. 50.9 %; p < 0.0001) in urban areas (100 vs. 93.0 %; p < 0.0001). RF was performed in 272 patients (3.5 %) and LF in 7,484 patients (96.5 %). RF patients were more often male compared with LF (38.2 vs. 32.3 %; p < 0.05); however, there was no difference in age, race, CCI, LOS, or postoperative complications. RF was more expensive than LF ($37,638 ± 21,134 vs. $32,947 ± 24,052; p < 0.0001), and more often performed at teaching hospitals (72.4 vs. 54.9 %; p < 0.0001) in urban areas (98.5 vs. 88.7 %; p < 0.0001).

CONCLUSIONS

This nationwide study of RAGS exemplifies its low but increasing incidence across the country. RAGS is regionalized to urban teaching centers compared with conventional laparoscopic techniques. Despite similar postoperative outcomes, there is significantly increased cost associated with RAGS.

Disparities in use of laparoscopic hysterectomies: a nationwide analysis

STUDY OBJECTIVE

To determine patient and hospital characteristics that were associated with undergoing laparoscopic hysterectomy compared with abdominal hysterectomy.

DESIGN

Canadian Task Force Classification II-3.

METHODS

In this retrospective cohort study, we analyzed the 2010 Healthcare Cost and Utilization Project Nationwide Inpatient Sample database. All women who underwent laparoscopic or abdominal hysterectomy for either menorrhagia or leiomyoma were included based on International Classification of Diseases, Ninth Revision coding. A linear model with binomial distribution and logit link function was used to determine patient and hospital characteristics associated with hysterectomy approach.

MAIN RESULTS

A total of 32 436 patients were included in this study. Of these, 32% patients underwent laparoscopic hysterectomies, and 67% underwent abdominal hysterectomies. With regard to patient characteristics, women younger than 35 years old were more likely to undergo laparoscopic hysterectomy when compared with each of the other age categories (p < .001). White women were more likely to undergo laparoscopic hysterectomy than black women, Hispanic women, or women classified as "other" races (p < .001 for all comparisons). With regard to median income, patients from the lowest national quartile were less likely to undergo laparoscopic hysterectomy when compared with each of the other 3 national quartiles for income (p = .01, p < .001, p = .001, respectively). Payment by private insurance was associated with laparoscopic hysterectomy when compared with payment by Medicare or payment by insurance category "other" (p < .001 for both). With regard to hospital characteristics, hospitals in the Northeast were more likely to have laparoscopic hysterectomies than hospitals in the Midwest or South (p < .001 for both comparisons); urban hospitals were more likely than rural hospitals (p < .001); teaching hospitals were more likely than nonteaching hospitals (p < .001); and government-owned hospitals were less likely than private, nonprofit or private, investor owned (p < .001 for both comparisons).

CONCLUSIONS

Despite the increased popularity of and training in laparoscopic hysterectomies, there remains an obvious disparity in its delivery with regard to patient and hospital characteristics. Further investigation is needed on the etiology of this disparity and interventions that may alleviate it.

Current national practice patterns for inpatient management of ventral abdominal wall hernia in the United States

BACKGROUND

The health-care burden related to ventral hernia management is substantial, with more than 3 billion dollars in expenditures annually in the US. Previous studies have suggested that the utilization of laparoscopic repair remains relatively low although national volume estimates have not been reported. We sought to estimate the inpatient national volume of elective ventral hernia surgery and characterize the proportion of laparoscopic versus open operations.

METHODS

We analyzed data from the Nationwide Inpatient Sample to identify adults with a diagnosis of an umbilical, incisional, or ventral hernia who underwent an elective inpatient repair between 2009 and 2010. Cases that involved other major abdominal or pelvic operations were excluded. Covariates included patient demographics, surgical approach, and use of mesh. National surgical volume estimates were generated and length of stay and total hospital charges were compared for laparoscopic versus open repairs.

RESULTS

A total of 112,070 ventral hernia repairs were included in the analysis: 72.1 % (n = 80,793) were incisional hernia repairs, while umbilical hernia repairs comprised only 6.9 % (n = 7,788). Laparoscopy was utilized in 26.6 % (n = 29,870) of cases. Mesh was placed in 85.8 % (n = 96,265) of cases, including 49.3 % (n = 3,841) of umbilical hernia repairs and 90.1 % (n = 72,973) of incisional hernia repairs. Length of stay and total hospital charges were significantly lower for laparoscopic umbilical, incisional, and "other" ventral hernia repairs (p values all <0.001). Total hospital charges during this 2-year period approached 4 billion dollars ($746 million for laparoscopic repair; $3 billion for open repair).

CONCLUSIONS

Utilization of laparoscopy for elective abdominal wall hernia repair remains relatively low in the US despite its excellent outcomes. Given the substantial financial burden associated with these hernias, future research focused on preventing the development and optimizing the surgical treatment of ventral abdominal wall hernias is warranted.

Minimally invasive surgery: national trends in adoption and future directions for hospital strategy

BACKGROUND

Surgeons have rapidly adopted minimally invasive surgical (MIS) techniques for a wide range of applications since the first laparoscopic appendectomy was performed in 1983. At the helm of this MIS shift has been laparoscopy, with robotic surgery also gaining ground in a number of areas.

METHODS

Researchers estimated national volumes, growth forecasts, and MIS adoption rates for the following procedures: cholecystectomy, appendectomy, gastric bypass, ventral hernia repair, colectomy, prostatectomy, tubal ligation, hysterectomy, and myomectomy. MIS adoption rates are based on secondary research, interviews with clinicians and administrators involved in MIS, and a review of clinical literature, where available. Overall volume estimates and growth forecasts are sourced from The Advisory Board Company's national demand model which provides current and future utilization rate projections for inpatient and outpatient services. The model takes into account demographics (growth and aging of the population) as well as non demographic factors such as inpatient to outpatient shift, increase in disease prevalence, technological advancements, coverage expansion, and changing payment models.

RESULTS

Surgeons perform cholecystectomy, a relatively simple procedure, laparoscopically in 96 % of the cases. Use of the robot as a tool in laparoscopy is gaining traction in general surgery and seeing particular growth within colorectal surgery. Surgeons use robotic surgery in 15 % of colectomy cases, far behind that of prostatectomy but similar to that of hysterectomy, which have robotic adoption rates of 90 and 20 %, respectively.

CONCLUSIONS

Surgeons are using minimally invasive surgical techniques, primarily laparoscopy and robotic surgery, to perform procedures that were previously done as open surgery. As risk-based pressures mount, hospital executives will increasingly scrutinize the cost of new technology and the impact it has on patient outcomes. These changing market dynamics may thwart the expansion of new surgical techniques and heighten emphasis on competency standards.

Postoperative surgical site infections after ventral/incisional hernia repair: a comparison of open and laparoscopic outcomes

BACKGROUND

The purpose of this study was to compare the incidence of postoperative surgical site infections (SSIs), operative times (OTs), and length of hospital stay (LOS) after open and laparoscopic ventral/incisional hernia repair (VIHR) using multicenter, prospectively collected data.

METHODS

The incidence of postoperative SSIs, OTs, and LOS was determined for cases of VIHR in the American College of Surgeons' National Surgical Quality Improvement Program database in 2009 and 2010. Open and laparoscopic techniques were compared using a propensity score model to adjust for differences in patient demographics, characteristics, comorbidities, and laboratory values.

RESULTS

A total of 26,766 cases met the inclusion criteria; 21,463 cases were open procedures (reducible, n = 15,520 [72 %]; incarcerated/strangulated, n = 5,943 [28 %]), and 5,303 cases were laparoscopic procedures (reducible, n = 3,883 [73 %]; incarcerated/strangulated, n = 1,420 [27 %]). Propensity score adjusted odds ratios (ORs) were significantly different between open and laparoscopic VIHR for reducible and incarcerated/strangulated hernias with regard to superficial SSI (OR 5.5, p < 0.01 and OR 3.1, p < 0.01, respectively), deep SSI (OR 6.9, p < 0.01, and OR 8.0, p < 0.01, respectively) and wound disruption (OR 4.6, p < 0.01 and OR 9.3, p = 0.03, respectively). The risk for organ/space SSI was significantly greater for open operations among reducible hernias (OR 1.9, p = 0.02), but there was no significant difference between the open and laparoscopic repair groups for incarcerated/strangulated hernias (OR 0.8, p = 0.41). The OT was significantly longer for laparoscopic procedures, both for reducible (98.5 vs. 84.9 min, p < 0.01) and incarcerated/strangulated hernias (96.4 vs. 81.2 min, p < 0.01). LOS (mean, 95 % confidence interval) was significantly longer for open repairs for both reducible (open = 2.79, 2.59-3.00; laparoscopic = 2.39, 2.20-2.60; p < 0.01) and incarcerated/strangulated (open = 2.64, 2.55-2.73; laparoscopic = 2.17, 2.02-2.33; p < 0.01) hernias.

CONCLUSIONS

Laparoscopic VIHR for reducible and incarcerated/strangulated hernias is associated with shorter LOS and decreased risk for superficial SSI, deep SSI, and wound disruption, but longer OTs when compared to open repair.
