The natural course of giant paraesophageal hernia and long-term outcomes following conservative management.

BACKGROUND: Accurate information on the natural course of giant paraesophageal hernia is scarce, challenging therapeutic decisions whether or not to operate. OBJECTIVE: We aimed to investigate the long-term outcomes, including hernia-related deaths and complications (e.g. volvulus, gastrointestinal bleeding, strangulation) of patients with giant paraesophageal hernia that were conservatively managed, and to determine factors associated with clinical outcome. METHODS: We retrospectively analysed charts of patients diagnosed with giant paraesophageal hernia between January 1990 and August 2019, collected from a university hospital in The Netherlands. Included patients were subdivided into three groups based on primary therapeutic decision at diagnosis. Radiological, clinical and surgical characteristics, along with long-term outcomes at most recent follow-up, were collected. RESULTS: We included 293 patients (91 men, mean age 70.3 ± 12.4 years) with a mean duration of follow-up of 64.0 ± 58.8 months. Of the 186 patients that were conservatively treated, a total hernia-related mortality of 1.6% was observed. Hernia-related complications, varying from uncomplicated volvulus to strangulation, occurred in 8.1% of patients. Only 1.1% of patients included in this study required emergency surgery. Logistic regression analysis revealed the presence of symptoms (odds ratio (OR) 4.4, 95% confidence interval (CI) 1.8-20.6), in particular obstructive symptoms (vomiting, OR 15.7, 95% CI 4.6-53.6; epigastric pain, OR 4.4, 95% CI 1.2-15.8 and chest pain, OR 6.1, 95% CI 1.8-20.6) to be associated with the occurrence of hernia-related complications. CONCLUSIONS: Hernia-related death and morbidity is low in conservatively managed patients. The presence of obstructive symptoms was found to be associated with the occurrence of complications during follow-up. Conservative therapy is an appropriate therapeutic strategy for asymptomatic patients.

Outcomes of laparoscopic hiatal hernia repair based on surgical specialty: thoracic versus general surgeons.

BACKGROUND: Hiatal Hernia Repairs (HHR) are performed by both general surgeons (GS) and thoracic surgeons (TS). However, there are limited literature with respect to outcomes of HHR based on specialty training. The objective of this study was to compare the utilization, perioperative outcomes, and cost for HHR performed by GS versus TS. METHODS: The Vizient database was used to identify patients who underwent elective laparoscopic HHR between October 2014 and June 2018. Patients were grouped according to surgeon's specialty (GS vs. TS). Patient demographics and outcomes including in-hospital mortality were compared between groups. RESULTS: During the study period 13,764 patients underwent HHR by either GS or TS. GS performed 9930 (72%) cases while TS performed 3834 (28%) cases. There was no significant difference between GS versus TS with regard to serious morbidity (1.28% vs. 1.30%, p = 0.97) or mortality (0.10% vs. 0.21%, p = 0.19). The mortality index was 0.24 for GS versus 0.45 for TS. Compared to TS, laparoscopic HHR performed by GS was associated with a shorter LOS (2.57 days vs. 2.72 days, p < 0.001) and lower mean hospital costs ($7139 vs. $8032, p < 0.0001). CONCLUSIONS: Within the context of academic centers, laparoscopic HHRs are mostly performed by GS with comparable outcome between general versus thoracic surgeons.

Is repairing giant hiatal hernia in patients over 80 worth the risk?

Patients with giant hiatal hernia (GHH) are often symptomatic and have significantly reduced quality of life (QoL). Advanced age is a predictor of increased morbidity and mortality in open hiatal surgery, however, outcomes of laparoscopic surgery in patients over the age of 80 are limited to case reports and small case series. Data was extracted from a prospectively maintained database. Consecutive patients over the age of 80 with GHH that have undergone surgery were included. Peri-operative mortality, complications, recurrence rates, use of acid suppressive medication and QoL was analysed. Search of Ryerson index was performed to determined post-operative survival. Inclusion criteria were met by 89 patients. Mean age was 84 (80-93). The mean volume of herniated stomach was 70.9% range 30-100%; SD 27.25). There was one death in this cohort on day 30 from myocardial infarction and one mediastinal collection requiring percutaneous radiological drainage and antibiotics. There were no other major complications (Clavien-Dindo Grade III-IV). Mean post-operative survival was 74.5 months (SD 47.8). GIQLI was reduced pre-operatively (mean 91.8; SD 19.4). There was significant improvement in GIQLI scores at early (mean 101.45; SD 21.2) and late (mean 106.7; SD 19.2) post-operative follow-up (p = 0.005). Pre-operative Visick scores (mean 2.92; SD 0.98) have improved significantly in early (mean 1.94; SD 0.97; p = 0.000) and late (mean 2.03; SD 0.99; p = 0.001) post-operative periods. Satisfaction with surgery was 97% during early and 93.3% during late post-operative follow up. Laparoscopic repair of GHH in appropriately selected elderly patients is safe and results in significant improvement in quality of life.

Novel homozygous OSGEP gene pathogenic variants in two unrelated patients with Galloway-Mowat syndrome: case report and review of the literature.

BACKGROUND: Galloway-Mowat syndrome (GAMOS) is a rare autosomal recessive disorder characterized by early-onset nephrotic syndrome and microcephaly with brain anomalies. WDR73 pathogenic variants were described as the first genetic cause of GAMOS and, very recently, four novel causative genes, OSGEP, LAGE3, TP53RK, and TPRKB, have been identified. CASE PRESENTATION: We present the clinical and genetic characteristics of two unrelated infants with clinical suspicion of GAMOS who were born from consanguineous parents. Both patients showed a similar clinical presentation, with early-onset nephrotic syndrome, microcephaly, brain atrophy, developmental delay, axial hypotonia, and early fatality. We identified two novel likely disease-causing variants in the OSGEP gene. These two cases, in conjunction with the findings of a literature review, indicate that OSGEP pathogenic variants are associated with an earlier onset of nephrotic syndrome and shorter life expectancy than WDR73 pathogenic variants. CONCLUSIONS: Our findings expand the spectrum of pathogenic variants in the OSGEP gene and, taken in conjunction with the results of the literature review, suggest that the OSGEP gene should be considered the main known monogenic cause of GAMOS. Early genetic diagnosis of GAMOS is of paramount importance for genetic counseling and family planning.

Watchful waiting versus elective repair for asymptomatic and minimally symptomatic paraesophageal hernias: A cost-effectiveness analysis.

OBJECTIVE: To evaluate the decision of watchful waiting (WW) versus elective laparoscopic hernia repair (ELHR) for minimally symptomatic paraesophageal hernias (PEH) with respect to cost-effectiveness. BACKGROUND: The current recommendation for minimally symptomatic PEHs is watchful waiting. This standard is based on a decision analysis from 2002 that compared the two strategies on quality-adjusted life-years (QALYs). Since that time, the safety of ELHR has improved. A cost-effectiveness study for PEH repair has not been reported. METHODS: A Markov decision model was developed to compare the strategies of WW and ELHR for minimally symptomatic PEH. Input variables were estimated from published studies. Cost data was obtained from Medicare. Outcomes for the two strategies were cost and QALY's. RESULTS: ELHR was superior to the WW strategy in terms of quality of life, but it was more costly. The average cost for a patient in the ELHR arm was 11,771 dollars while for the WW arm it was 2207. CONCLUSION: This study shows that WW and ELHR both have benefits in the management of minimally symptomatic paraesophageal hernias.

Influence of national centralization of oesophagogastric cancer on management and clinical outcome from emergency upper gastrointestinal conditions.

BACKGROUND: In England in 2001 oesophagogastric cancer surgery was centralized. The aim of this study was to evaluate whether centralization of oesophagogastric cancer to high-volume centres has had an effect on mortality from different emergency upper gastrointestinal conditions. METHODS: The Hospital Episode Statistics database was used to identify patients admitted to hospitals in England (1997-2012). The influence of oesophagogastric high-volume cancer centre status (20 or more resections per year) on 30- and 90-day mortality from oesophageal perforation, paraoesophageal hernia and perforated peptic ulcer was analysed. RESULTS: Over the study interval, 3707, 12 441 and 56 822 patients with oesophageal perforation, paraoesophageal hernia and perforated peptic ulcer respectively were included. There was a passive centralization to high-volume cancer centres for oesophageal perforation (26·9 per cent increase), paraoesophageal hernia (19·5 per cent increase) and perforated peptic ulcer (23·0 per cent increase). Management of oesophageal perforation in high-volume centres was associated with a reduction in 30-day (HR 0·58, 95 per cent c.i. 0·45 to 0·74) and 90-day (HR 0·62, 0·49 to 0·77) mortality. High-volume cancer centre status did not affect mortality from paraoesophageal hernia or perforated peptic ulcer. Annual emergency admission volume thresholds at which mortality improved were observed for oesophageal perforation (5 patients) and paraoesophageal hernia (11). Following centralization, the proportion of patients managed in high-volume cancer centres that reached this volume threshold was 88·0 per cent for oesophageal perforation, but only 30·3 per cent for paraoesophageal hernia. CONCLUSION: Centralization of low incidence conditions such as oesophageal perforation to high-volume cancer centres provides a greater level of expertise and ultimately reduces mortality.

Laparoscopic Repair of Large Hiatal Hernia Without the Need for Esophageal Lengthening With Low Morbidity and Rare Symptomatic Recurrence.

The aim of this study was to assess symptomatic recurrence in patients who underwent a laparoscopic repair of large hiatal hernia without an esophageal lengthening procedure. Patients who underwent a laparoscopic repair of a large hiatal hernia from September 2009 to September 2015 by a single surgeon were identified in the retrospective review. The patients were followed up prospectively by the operating surgeon using a structured questionnaire, administered by telephone, to assess the symptoms. Symptomatic recurrence was defined as the requirement for a reoperative procedure for symptomatic recurrent hiatal hernia. There were 215 laparoscopic repairs. Reoperations (n = 35) and type I hernias of <4 cm (n = 49) were excluded. The study population included 131 patients: 36 had type I hernia, 4 had type II hernia, 37 had type III hernia, and 54 had type IV hernia. There were 102 women and 29 men, aged 63 (56-74) years. For repair, 102 Toupet, 28 Nissen, and 1 Dor fundoplications were performed. The duration of the operation was 138 (119-172) minutes. Adequate esophageal length was obtained by mediastinal esophageal mobilization in all patients, without Collis gastroplasty. A mesh was used in 106 patients. There was 1 conversion and 2 delayed esophageal leaks. The length of stay was 2 (1-3) days. Perioperative complications included atrial fibrillation in 5 patients, gastric distension or ileus in 5 patients, reintubation in 3 patients, heparin-induced thrombocytopenia in 1 patient, and temporary dialysis in 1 patient. There was no 30-day or in-hospital mortality. The questionnaire was completed by 99 out of 131 patients (76%) at 24 (9-38) months; of the 99 patients, 85 (86%) were free of preoperative symptoms; 91 (92%) were satisfied with the operation; and 73 (74%) were off proton pump inhibitors. Reoperation for symptomatic recurrent hiatal hernia occurred in 8 of the 99 patients (8%), 2 in the perioperative period and 6 at 25 (8-31) months. Laparoscopic repair of large hiatal hernia can be performed with low morbidity and results in excellent patient satisfaction. Tension-free, intra-abdominal esophageal length can be achieved laparoscopically without Collis gastroplasty. Reoperation for symptomatic recurrence is rare.

Effect of Esophageal Cancer Surgeon Volume on Management and Mortality From Emergency Upper Gastrointestinal Conditions: Population-based Cohort Study.

OBJECTIVE: To study the influence of esophageal cancer surgeon volume upon mortality from upper gastrointestinal emergencies. BACKGROUND: Volume-outcome relationships led to the centralization of esophageal cancer surgery. METHODS: Hospital Episode Statistics data were used to identify patients admitted to hospitals within England (1997-2012). The influence of esophageal high-volume (HV) cancer surgeon status (≥5 resections per year) upon 30-day and 90-day mortality from esophageal perforation (EP), paraesophageal hernia causing obstruction or gangrene (PEH) and perforated peptic ulcer (PPU) was analyzed, independent of HV esophageal cancer center status and patient and disease-specific confounding factors. RESULTS: A total of 3707, 12,411, and 57,164 patients with EP, PEH, and PPU, respectively, were included. The observed 90-day mortality was 36.5%, 11.5%, and 29.0% for EP, PEH, and PPU, respectively.Management by HV cancer surgeon was independently associated with significant reductions in 30-day and 90-day mortality from EP (odds ratio, OR 0.51, 95% confidence interval, CI, 0.40-0.66), PEH (OR=0.70, 95% CI 0.53-0.91), and PPU (OR=0.85, 95% CI 0.7-0.95). Subset analysis of those patients receiving primary surgery as treatment showed no change in mortality when performed by HV cancer surgeons.However HV cancer surgeons performed surgery as primary treatment more commonly for EP (OR=2.38, 95% CI 1.87-3.04) and PEH (OR=2.12, 95% CI 1.79-2.51). Furthermore surgery was independently associated with reduced mortality for all 3 conditions. CONCLUSION: The complex elective workload of HV esophageal cancer surgeons appears to lower the threshold for surgical intervention in specific upper gastrointestinal emergencies such as EP and PEH, which in turn reduces mortality.

Practice Patterns and Outcomes After Hospital Admission With Acute Para-esophageal Hernia in England.

OBJECTIVE: (i) To establish at a national level clinical outcomes from patients presenting with acute para-esophageal hernia (PEH); and (ii) to determine if a hospital volume-outcome relationship exists for the management of acute PEH. BACKGROUND: Currently, no clear guidelines exist regarding the management of acute PEH, and practice patterns are based upon relatively small case series. METHODS: Patients admitted as an emergency for the treatment of acute PEH between 1997 and 2012 were included from the Hospital Episode Statistics database. The influence of hospital volume upon clinical outcomes was analyzed in unmatched and matched comparisons to control for patient age, medical comorbidities, and incidence of PEH hernia gangrene. RESULTS: Over the 16-year study period, 12,441 patients were admitted as an emergency with a PEH causing obstruction or gangrene. Of these, 90.8% patients were admitted with PEH with obstruction in the absence of gangrene and 9.2% with PEH with gangrene. The incidences of 30 and 90-day mortality were 7% and 11.5%, respectively, which did not decrease during the study period. Unmatched and matched comparisons showed, in high-volume centers, there were significant reductions in utilization of emergency surgery (8.8% vs 14.9%; P < 0.0001), 30-day (5.3% vs 7.8%; P < 0.0001), and 90-day mortality (9.3% vs 12.7%; P < 0.0001). Multivariate analysis also confirmed high hospital volume was independently associated with reduced 30 and 90-day mortality from acute PEH. CONCLUSIONS: Acute PEH represents a highly morbid condition, and treatment in high-volume centers provides the appropriate multidisciplinary infrastructure to manage these complex patients reducing associated mortality.

The impact of frailty on outcomes of paraesophageal hernia repair.

BACKGROUND: Frailty is a measure of physiological reserve that has been used to predict outcomes after surgical procedures in the elderly. We hypothesized that frailty would be associated with outcomes after paraesophageal hernia (PEH) repair. METHODS: The National Surgical Quality Improvement Program database (2011-2013) was queried for International Classification of Diseases, Version 9 and Current Procedural Terminology codes associated with PEH repair in patients aged ≥ 60 y. A previously described modified frailty index (mFI), based on 11 clinical variables in National Surgical Quality Improvement Program was used to quantify frailty. Multivariate logistic regression was used to determine the relationship between frailty, complications, and mortality. RESULTS: Of the 4434 PEH repairs that met inclusion criteria, 885 records were included in the final analysis (20%). Excluded patients were missing one or more variables in the mFI. The rate of complications that were Clavien-Dindo Grade ≥ 3 was 6.1%. Mortality was 0.9%. The readmission rate was 8.2%, and 10.9% of patients were discharged to a facility other than home. Relative to mFI scores of 0, 1, 2, and ≥3, the respective occurrence percentages were as follows; Grade ≥3 complication: 3.2%, 4.7%, 9.8%, and 23.3% (P < 0.0001; odds ratio [OR] 3.51; confidence interval [CI] 1.46-8.46); mortality: 0.0%, 0.9%, 1.8%, and 2.3% (P = 0.0974); discharge to facility other than home: 4.4%, 10.9%, 15.7%, and 31.7% (P < 0.0001; OR 4.07; CI 1.29-12.82); and readmission: 8.9%, 6.8%, 8.5%, and 16.3% (P = 0.1703; OR 1.01; CI 0.36-2.84). Complications and discharge destination were significantly correlated with the mFI. CONCLUSIONS: Frailty, as assessed by the mFI, is correlated with postoperative complications and discharge to a facility other than home after PEH repair.

Laparoscopic Hiatal Hernia Repair in the Elderly Patient.

BACKGROUND: Hiatal hernias (HH) are more common among elderly patients, with an increase in incidence with advancing age. Elderly patients frequently suffer from comorbidity, causing them to have an increased risk of perioperative mortality and morbidity. The aim of this study is to assess the safety of this procedure within elderly patients. METHODS: We performed a retrospective analysis of all patients with HH operated between July 2009 and May 2015 at two hospitals in the Netherlands specialized in antireflux surgery and HH repair. Mortality rates and short- and long-term morbidity rates were compared between patients aged under 70 years and aged over 70 years. RESULTS: A total of 204 consecutive patients underwent laparoscopic HH repair at our institutions, of whom 121 were aged under 70 years and 83 were aged over 70 years. There was no mortality intraoperatively, nor during 30-days follow-up. Intraoperative complications occurred in 7 patients aged 70 years and over, with no significant differences compared to the patients aged under 70. The 30-day morbidity rate did not significantly differ between the age groups, with an overall postoperative complication rate of 9.3 %. Only length of stay (LOS) was significantly longer in the elderly patients. Performing univariate analysis, only the occurrence of intraoperative complications was associated with 30-day morbidity. CONCLUSION: In the present study, age was not associated with increased 30-day morbidity or mortality following HH repair. Therefore, in carefully selected patients, age should not be used as an argument to withhold laparoscopic HH repair.

[Report of 12 years experience in the surgical treatment of 286 paraesophageal hernias]. / Erfahrungen aus 12 Jahren chirurgischer Versorgung von 286 paraösophagealen Hernien.

BACKGROUND: In contrast to axial hiatus hernias, paraesophageal hernias are rare but can lead to chronic iron deficiency anemia and severe acute complications. Treatment is manifold and consistent standards are lacking. OBJECTIVES: The aim of this study was to describe our experiences of 286 patients with paraesophageal hernias, who underwent surgery from 2003 to 2014 at a tertiary referral center. The study was particularly concerned with morbidity, mortality, quality of life and recurrence rates. MATERIAL AND METHODS: In 12 years a total of 286 paraesophageal hernias were surgically treated, 255 with a minimally invasive procedure and 31 with an open approach. In 138 patients (48 %) the suture-based hiatoplasty was reinforced by means of a lightweight mesh, which was fixed with fibrin glue in 90 cases. Abdominal fixation of the stomach consisted of a gastropexy and anterior (n = 244) or posterior (n = 42) fundoplication. RESULTS: Complications arose in 8.4 % of the patients. The mean hospital stay was 5.3 (± 2.8) days for elective surgery and 24.7 (± 17.8) days for emergency operations. The gastrointestinal quality of life index according to Eypasch significantly increased from mean preoperative values of 92.8 (± 22.5) to 109.6 (± 20.2) in the postoperative course (p < 0.001). Of the patients 20 (7 %) suffered a recurrence requiring surgery, including 7 early and 13 late recurrences. During the immediate postoperative period radiographically detected recurrences were promptly revised. The strategy of late recurrences in the long-term course was based on patient symptoms and asymptomatic hernias were treated conservatively while symptomatic hernias were surgically treated. Symptomatic late recurrences developed in 4.6 % of the patients, including 7.4 % (11 out of 148) without and 1.4 % (2 out of 138) with primary mesh repair. CONCLUSION: The repair of paraesophageal hernias in 286 patients provided excellent patient satisfaction and symptom improvement with low perioperative morbidity and mortality. Mesh reinforcement reduced the recurrence rate. The quality of life index is a suitable clinical course parameter for evaluation of paraesophageal hernias.

Emergent Surgery Does Not Independently Predict 30-Day Mortality After Paraesophageal Hernia Repair: Results from the ACS NSQIP Database.

AIM: Patients undergoing emergency surgery for paraesophageal hernia (PEH) repair have a higher adjusted mortality risk based on Nationwide Inpatient Sample (NIS). We sought to examine this relationship in the National Surgical Quality Improvement Program (NSQIP), which adjusts for patient-level risk factors, including factors contributing to patient frailty. METHODS: This is a retrospective analysis of the NSQIP from 2009 through 2011. A modified frailty index was created based on previously validated methodology. RESULTS: Of 3498 patients with PEH repair, 175 (5 %) underwent emergent surgery. Older age, lower BMI, chronic obstructive pulmonary disease (COPD), congestive heart failure (CHF), current dialysis, SIRS, and sepsis were significantly more common among emergent patients. These patients also had a poorer functional status, higher American Society of Anesthesiologists (ASA), and higher frailty scores and more likely to undergo open surgery. Postoperative complications were proportionally more common, and LOS was longer (8.5 vs. 3.4 days) among emergent patients (all p < 0.05). In univariate analysis, emergent patients demonstrated ten times greater mortality than the elective surgery group (8 vs. 0.8 %). On adjusted analysis, emergent surgery was no longer independently associated with mortality. Frailty score 2 or above and preoperative sepsis significantly predicted increased mortality while laparoscopic repair and BMI 25-50 and BMI ≥30 (vs. BMI <18.5) were significantly protective in the entire group of patients. CONCLUSION: Increased mortality among patients undergoing emergent PEH repair may be related to severity of disease and other preoperative comorbid illness. Without an emergent indication, some of these patients likely would have been excluded as candidates for elective surgical intervention.

Improved patient outcomes in paraesophageal hernia repair using a laparoscopic approach: a study of the national surgical quality improvement program data.

A consensus on the optimal surgical approach for repair of a paraesophageal hernia has not been reached. The aim of this study was to examine the outcomes of open and laparoscopic paraesophageal hernia repairs (PHR), both with and without mesh. A review of the National Surgical Quality Improvement Program (NSQIP) database from 2007 to 2011 was conducted. Patients who underwent an open or laparoscopic PHR were included. The primary outcome was 30-day mortality. Secondary outcomes included infections, respiratory and cardiac complications, intraoperative or perioperative transfusions, sepsis, and septic shock. Statistical analyses using odds ratios were performed comparing the open and laparoscopic approaches. A total of 4470 patients were identified using NSQIP; 2834 patients had a laparoscopic repair and the remaining 1636 patients underwent an open PHR. Compared with the laparoscopic approach, the open repair group had significantly higher 30-day mortality (odds ratio, 4.75; 95% confidence interval, 2.67 to 8.47; P < 0.0001). The laparoscopic approach had a statistically significant decrease in infections, respiratory and cardiac events/complications, transfusion requirements, episodes of sepsis, and septic shock (P < 0.05). Our data suggest increased perioperative morbidity associated with an open PHR compared with laparoscopic. There was no statistically significant difference in any of the primary or secondary outcomes in patients repaired with mesh compared with those without. The overall use of mesh in paraesophageal hernia repairs has increased. The NSQIP data show significantly increased 30-day mortality in open repair compared with laparoscopic as well as a significantly higher perioperative complication rate.

Thirty-day outcomes of paraesophageal hernia repair using the NSQIP database: should laparoscopy be the standard of care?

BACKGROUND: Although surgical repair is universally recognized as the gold standard for treatment of paraesophageal hernia (PEH), the optimal surgical approach is still the subject of debate. To determine which surgical technique is safest, we compared the outcomes of laparoscopic (lap), open transabdominal (TA), and open transthoracic (TT) PEH repair using the NSQIP database. STUDY DESIGN: From 2005 to 2011, we identified 8,186 patients who underwent a PEH repair (78.4% lap, 19.2% TA, 2.4% TT). Primary outcome measured was 30-day mortality. Secondary outcomes included hospital length of stay, and NSQIP-measured postoperative complications. Multivariable analyses were performed to compare the odds of each outcome across procedure type (lap, TA, and TT) while adjusting for other factors. RESULTS: Transabdominal patients had the highest 30-day mortality rate (2.6%), compared with 0.5% in the lap patients (p < 0.001) and 1.5% in TT patients. Mean length of stay was statistically significantly longer for TA and TT patients (7.8 days and 6.5 days, respectively) compared with lap patients (3.3 days). After adjusting for age, American Society of Anesthesiologists score, emergency cases, functional status, and steroid use, TA patients were nearly 3 times as likely as lap patients to experience 30-day mortality (odds ratio [OR], 2.97; 95% CI, 1.69 to 5.20; p < 0.001). Moreover, TA and TT patients had significantly increased odds of overall (OR 2.12; 95% CI 1.79 to 2.51; p < 0.001; OR 2.73; 95% CI 1.88 to 3.96; p < 0.001; respectively) and serious morbidity (OR 1.90; 95% CI 1.53 to 2.37, p < 0.001; OR 2.49; 95% CI 1.54 to 4.00; p < 0.001; respectively). CONCLUSIONS: In the absence of published data indicating improved long-term outcomes after open TA or TT approach, our findings support the use of laparoscopy, whenever technically feasible, because it yields improved short-term outcomes.

Hiatal hernia repair in laparoscopic adjustable gastric banding and laparoscopic Roux-en-Y gastric bypass: a national database analysis.

Hiatal hernia (HH) repairs are commonly done concomitantly with laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic adjustable gastric banding (LAGB) to decrease gastroesophageal reflux disease (GERD). There is limited evidence about the additional surgical risk these combined procedures engender. We used the United States Nationwide Inpatient Sample 2004-2009 to compare mortality risk, prolonged length of stay (PLOS), and perioperative adverse events using propensity score-matched analysis. We repeated the analysis after removing patients diagnosed with GERD. There were 42,272 weighted patients undergoing LRYGB alone representing 206,559 discharges nationally and an additional 1,945 and 9,060, respectively, undergoing LRYGB + HH repair. For LAGB, there were 10,558 records representing 52,901 LAGB-only discharges and 1,959 representing 9,893 LAGB + HH repair discharges. Thirty-eight percent (95 % CI: 36, 41 %) of the patients in the LRYGB-only group had GERD compared to 55 % (51, 59 %) in the LRYGB + HH repair group. Among the LAGB groups, 31 % (28, 34 %) of LAGB-only patients had GERD compared to 44 % (38, 49 %) in the LAGB + HH repair group. We find that the average treatment effect on the treated (considering the concomitant procedure as treatment and the single procedure as control) for PLOS was -0.12353 (-0.15909, -0.08797) between the LRYGB groups and -0.04353 (-0.07488, -0.01217) for the LAGB groups. We find no evidence of increased risk of perioperative adverse events among patients undergoing concomitant HH repair with LRYGB or LAGB. Patients undergoing the combined procedure appear to be at lower risk of PLOS; this may be due to surgical training norms.

Urgent laparoscopic repair of acutely symptomatic PEH is safe and effective.

BACKGROUND: Acute incarceration of paraesophageal hernias (PEHs) requiring urgent or emergent surgery is rare. Patients are often elderly with significant comorbidities and have historically been treated with open abdominal or thoracic incisions. Our study was designed to evaluate the feasibility, safety, and efficacy of laparoscopic paraesophageal hernia repair (LPEHR) in patients with PEH and acute gastric volvulus. METHODS: We reviewed our prospectively maintained database and identified 269 patients who underwent an initial LPEHR between January 2003 and January 2012. Patients were divided into group A (acute), group B (age- and comorbidity-matched 1:3), and group C (all elective repairs). Group A included those admitted with acute symptoms related to PEH and underwent urgent repair. Patient age, Charlson score, operative time, length of stay (LOS), morbidity, mortality, and recurrence rates were compared. RESULTS: Patients who underwent urgent LPEHR had a higher perioperative morbidity rate than the elective and matched groups. The overall mortality rate was low and no statistical difference was found between groups A, B, and C. LOS in group A was longer than groups B and C. The need for ICU admission was also higher in group A. There was no statistical difference in recurrence rates. CONCLUSIONS: Historically, patients presenting with acute symptoms related to PEH have required open repair, which is associated with significant morbidity and mortality. The acute group was older and sicker than our elective LPEHR patients and had more adverse events resulting in a longer LOS, even when compared with comorbidity-matched elective patients. However, the LOS remained shorter than that reported for open repair and there was no mortality. The recurrence rates in all groups were low and comparable to elective repairs.

Open versus laparoscopic hiatal hernia repair.

BACKGROUND: The literature reports the efficacy of the laparoscopic approach to paraesophageal hiatal hernia repair. However, its adoption as the preferred surgical approach and the risks associated with paraesophageal hiatal hernia repair have not been reviewed in a large database. METHOD: The Nationwide Inpatient Sample dataset was queried from 1998 to 2005 for patients who underwent repair of a complicated (the entire stomach moves into the chest cavity) versus uncomplicated (only the upper part of the stomach protrudes into the chest) paraesophageal hiatal hernia via the laparoscopic, open abdominal, or open thoracic approach. A multivariate analysis was performed controlling for demographics and comorbidities while looking for independent risk factors for mortality. RESULTS: In total, 23,514 patients met the inclusion criteria. By surgical approach, 55% of patients underwent open abdominal, 35% laparoscopic, and 10% open thoracic repairs. Length of stay was significantly reduced for all patients after laparoscopic repair (P < .001). Age ≥60 years and nonwhite ethnicity were associated with significantly higher odds of death. Laparoscopic repair and obesity were associated with lower odds of death in the uncomplicated group. CONCLUSION: Laparoscopic repair of paraesophageal hiatal hernia is associated with a lower mortality in the uncomplicated group. However, older age and Hispanic ethnicity increased the odds of death.

A clinical prediction rule for perioperative mortality and major morbidity after laparoscopic giant paraesophageal hernia repair.

OBJECTIVE: In the current era, giant paraesophageal hernia repair by experienced minimally invasive surgeons has excellent perioperative outcomes when performed electively. However, nonelective repair is associated with significantly greater morbidity and mortality, even when performed laparoscopically. We hypothesized that clinical prediction tools using pretreatment variables could be developed that would predict patient-specific risk of postoperative morbidity and mortality. METHODS: We assessed 980 patients who underwent giant paraesophageal hernia repair (1997-2010; 80% elective and 97% laparoscopic). We assessed the association between clinical predictor covariates, including demographics, comorbidity, and urgency of operation, and risk for in-hospital or 30-day mortality and major morbidity. By using forward stepwise logistic regression, clinical prediction models for mortality and major morbidity were developed. RESULTS: Urgency of operation was a significant predictor of mortality (elective 1.1% [9/778] vs nonelective 8% [16/199]; P < .001) and major morbidity (elective 18% [143/781] vs nonelective 41% [81/199]; P < .001). The most common adverse outcomes were pulmonary complications (n = 199; 20%). A 4-covariate prediction model consisting of age 80 years or more, urgency of operation, and 2 Charlson comorbidity index variables (congestive heart failure and pulmonary disease) provided discriminatory accuracy for postoperative mortality of 88%. A 5-covariate model (sex, age by decade, urgency of operation, congestive heart failure, and pulmonary disease) for major postoperative morbidity was 68% predictive. CONCLUSIONS: Predictive models using pretreatment patient characteristics can accurately predict mortality and major morbidity after giant paraesophageal hernia repair. After prospective validation, these models could provide patient-specific risk prediction, tailored for individual patient characteristics, and contribute to decision-making regarding surgical intervention.
