Perioperative outcomes of robotic versus laparoscopic paraesophageal hernia repair: a NSQIP analysis

BACKGROUND

Studies comparing outcomes between robotic and laparoscopic paraesophageal hernia repairs have yielded conflicting results. We sought to analyze early postoperative complications between these approaches using a newly available NSQIP variable indicating robot use.

METHODS

We queried the 2022 ACS NSQIP database for adult patients undergoing elective minimally invasive hiatal hernia repair. Chi-squared and Kruskal-Wallis tests were used to compare cohort characteristics. Logistic, linear, and Cox proportional hazards regression analyses were used to compare perioperative outcomes between the laparoscopic and robotic groups.

RESULTS

We identified 4345 patients who underwent repair using a laparoscopic (2778 patients; 63.9%) or robotic (1567 patients; 36.1%) approach. Most (73.1%) were female, and the median age was 65 (IQR 55, 73). Patients who underwent robotic repair were younger (median age 64 vs 66), had a slightly higher body mass index (BMI; median 30.2 vs 29.9), and were more likely to have hypertension (53.0% vs 48.5%), all p < 0.01. On unadjusted analysis the robotic approach was associated with decreased 30-day mortality (0.0% vs 0.4%, p < 0.01). After adjusting for age, gender, race, BMI, and hypertension, the robotic approach was not associated with increased major complications (5.6% vs 5.1%, AOR 1.13, 95% CI 0.86, 1.49), minor complications (0.9% vs 1.5%, AOR 1.20, 95% CI 0.74, 1.93), or unplanned readmission (6.5% vs 5.5%, AHR 1.17, 95% CI 0.89, 1.54), all p ≥ 0.26. After adjusting for age and hypertension, the robotic cohort had an increased risk of myocardial infarction (AOR 2.53, 95% CI 1.01, 6.33, p = 0.048) and pulmonary embolism (AOR 2.76, 95% CI 1.17, 6.49, p = 0.02), although none resulted in 30-day mortality.

CONCLUSIONS

Robotic and laparoscopic paraesophageal hernia repairs had similar overall complication and readmission rates. The robotic cohort had an increased risk of myocardial infarction and pulmonary embolism but no 30-day mortality. Current data support the use of both robotic and laparoscopic approaches for paraesophageal hernia repair.

Venous Thromboembolism Chemical Prophylaxis in Patients Undergoing Shoulder Arthroscopy

» Venous thromboembolism (VTE) after shoulder arthroscopy is rare (0.01%-0.38%) but impacts a significant number of patients because of the high procedure volume.» Studies found no significant benefit in reducing VTE risk with aspirin or low-molecular-weight heparins.» Current guidelines for thromboprophylaxis in shoulder arthroscopy lack consensus and need patient-specific considerations.» Further research is required to develop evidence-based thromboprophylaxis guidelines for shoulder arthroscopy.

Revision Total Hip Arthroplasty in Octogenarians Compared with Septuagenarians: Is There a Real Difference?

BACKGROUND

The increasing frequency of total hip arthroplasty (THA) as well as an aging population indicate that the need for revision THA will continue to grow, especially in older and potentially medically complex patients. The purpose of this study was to compare THA revision indications, perioperative complications, and readmissions between octogenarian and septuagenarian patients. We hypothesized that patients aged 80 to 89 years would have similar outcomes to patients aged 70 to 79 years undergoing revision THA.

METHODS

Between 2008 and 2019, 572 revision THAs were performed at a single tertiary care hospital. Patients were stratified by age group: 70 to 79 years (n = 407) and 80 to 89 years (n = 165). Indication for revision, perioperative medical complications, and 90-day readmission were identified for each patient. Chi-square tests and t-tests were used to compare the groups. Logistic regression was used to assess medical complications and readmissions.

RESULTS

Aseptic loosening was a more common indication for revision in patients aged 70 to 79 years (33.4% versus 26.7%; p < 0.001), while periprosthetic fracture was a more common indication for revision in those aged 80 to 89 years (30.9% versus 13.0%). Perioperative medical complications occurred more often in octogenarians (10.9% versus 3.0%; p = 0.001), with arrythmia being the most common type. Patients aged 80 to 89 years were at increased risk for medical complications (odds ratio [OR], 3.2; 95% confidence interval [CI], 1.5 to 7.3; p = 0.004) and readmission (OR, 3.2; 95% CI, 1.7 to 6.3; p < 0.001) when adjusting for body mass index (BMI) and indication for revision. Octogenarians had a higher rate of reoperation following first-time revision than septuagenarians (10.3% versus 4.2%, p = 0.009).

CONCLUSIONS

Octogenarians more commonly underwent revision THA for periprosthetic fracture and had higher rates of perioperative medical complications, 90-day readmissions, and reoperations than septuagenarians. Such findings should be considered when counseling patients on both primary and revision THAs.

The use of absorbable skin stapler in mastectomy does not increase the rate of surgical site infection

Purpose

The use of absorbable skin staplers (ASS) for skin closure has been increasing due to their convenience and time-saving effect. In this study, we evaluated the effectiveness of ASS in reducing skin closure time and its safety regarding surgical site infection (SSI), comparing it to conventional hand sewing (HS) in patients who underwent mastectomy.

Methods

A single-center, retrospective study was conducted. The electronic medical records of patients who underwent mastectomy between July 2015 and June 2020 in Samsung Medical Center were reviewed. The data included previously known risk factors for SSI. We compared the time expended on skin closure and the occurrence rate of SSI between the ASS group and the HS group.

Results

We included 4,311 patients in the analysis. Among them, 520 patients were treated with ASS and 3,791 patients with HS. The average time for skin closure was 16.2 ± 10.1 minutes in the ASS group and 36.5 ± 29.0 minutes in the HS group (P < 0.001). The SSI rate was 0.38% (2 of 520) in the ASS group and 0.36% (14 of 3,791) in the HS group (P > 0.999).

Conclusion

The use of ASS in mastectomy reduced the time for skin closure significantly but did not increase the SSI. Therefore, it can be an effective and safe choice to use ASS instead of HS for skin closure in mastectomy.

Removing Well-Fixed, Collared and Noncollared Tapered Hip Stems Without an Extended Trochanteric Osteotomy Using a Novel Stem Removal System

Improvements in materials, components, and surgical techniques in cementless total hip arthroplasty are resulting in improved femoral stem fixation through bony ongrowth or ingrowth. While improved femoral stem fixation is one reason for the current excellent total hip survivorship, indications for stem removal such as infection, implant fracture, or osteolysis remain. A commonly used technique for fully ingrown femoral stems is an extended trochanteric osteotomy which can result in comminuted fractures of the proximal femur during stem removal requiring additional fixation. Therefore, a novel hip stem removal was developed to facilitate removal of these well-ingrown stems without the need for an extended trochanteric osteotomy. This study describes the removal system and surgical technique and presents a case series of successfully removed ingrown stems.
