An Ethical Framework for Disclosing the Training Status and Roles of Resident-Level Surgeons to Patients

The concept of informed consent includes disclosure of all information that a reasonable patient would need to make a well-informed decision about whether to undergo a surgical procedure. This has traditionally been defined as including diagnosis, details about the procedure, prognosis, potential risks, and alternative treatments. The operating surgeon has final say and responsibility for the case, but the actual operation may be done (under supervision) by a surgeon in training. In this paper, we discuss the ethical dimensions of disclosing resident involvement, reviewing considerations such as established legal and professional standards, consequences for patients and for the surgical educators responsible for preparing future generations of surgeons, and patient rights. We conclude by offering a novel ethical framework intended to serve as a guide to disclosing resident involvement as part of the overall consent process.

Machine Learning Analysis of Postlaparoscopy Hernias and "I'm Leaving You to Close" Strategy

INTRODUCTION

Contributing factors to postlaparoscopy hernia are unknown. We hypothesized that postlaparoscopy incisional hernias are increased when the index surgery was performed in teaching hospitals. Laparoscopic cholecystectomy was chosen as the archetype for open umbilical access.

MATERIALS AND METHODS

Maryland and Florida SID/SASD databases (2016-2019) wereused to track 1-year hernia incidence in both inpatient and outpatient settings, which was then linked to Hospital Compare, Distressed Communities Index (DCI), and ACGME. Postoperative umbilical/incisional hernia following laparoscopic cholecystectomy was identified using CPT and ICD-10. Propensity matching and eight machine learning modes were utilized including logistic regression, neural network, gradient boosting machine, random forest, gradient boosted trees, classification and regression trees, k nearest neighbors and support vector machines.

RESULTS

Postoperative hernia incidence was 0.2% (total = 286; 261 incisional and 25 umbilical) in 117,570 laparoscopic cholecystectomy cases. Days to presentation (mean ± SD) were incisional 141 ± 92 and umbilical 66 ± 74. Logistic regression performed best (AUC 0.75 (95% ci 0.67-0.82) and accuracy 0.68 (95% ci 0.60-0.75) using 10-fold cross validation) in propensity matched groups (1:1; n = 279). Postoperative malnutrition (OR 3.5), hospital DCI of comfortable, mid-tier, at risk or distressed (OR 2.2 to 3.5), LOS >1 d (OR 2.2), postop asthma (OR 2.1), hospital mortality below national average (OR 2.0) and emergency admission (OR 1.7) were associated with increased hernias. A decreased incidence was associated with patient location of small metropolitan areas with <1 million residents (OR 0.5) and Charlson Comorbidity Index-Severe (OR 0.5). Teaching hospitals were not associated with postoperative hernia after laparoscopic cholecystectomy.

CONCLUSIONS

Different patient factors as well as underlying hospital factors are associated with postlaparoscopy hernias. Performance of laparoscopic cholecystectomy at teaching hospitals is not associated with increased postoperative hernias.

Time-efficiency and hospital costs of open compared with laparoscopic groin hernia repair in a teaching hospital

BACKGROUND

Time efficiency and hospital costs may influence the preferred method of groin hernia repair. Despite growing expertise in laparoscopic hernia repair, knowledge on the actual costs and the potential financial advantages over open hernia repair are limited.

METHODS

A single-center retrospective cohort study comparing hospital costs and time-efficiency of open-mesh (Lichtenstein) and laparoscopic groin hernia repair between 2010 and 2015, including a comparison of surgeons and residents, was conducted. Secondary outcomes were length of hospital stay, complication and recurrence rates.

RESULTS

Nine hundred forty-seven open and 449 laparoscopic groin hernia repairs were included. Unilateral open repair showed a shorter operation theatre occupancy (63.5 min±17.2 vs. 71.9 min±19.9, P<0.001) and lower total costs (€ 974.51±266.67 vs. € 1165.32±285.94, P<0.001) compared with laparoscopic repair. Residents had longer operative times compared with surgeons in the unilateral open procedure (43.8±13.4 min vs. 34.5±16.3 min, P<0.001), in the unilateral laparoscopic procedure (46.9±16.6 min vs. 41.7±18.7 min, P<0.001) and higher total costs in the unilateral open procedure (€ 1007.47±238.58 vs. € 909.35±305.00, P<0.001). There were no significant differences in complication and recurrence rates between residents and surgeons.

CONCLUSIONS

Open-mesh hernia repair appears to be superior in costs for both uni- and bilateral groin hernias when performed by surgeons as well as residents. Residents had higher total costs and longer operation times in the unilateral open groin hernia group when compared with surgeons, yet overall complications and recurrence rates were similar in all groups suggesting that residents are sometimes more expensive and slower, but just as safe.

The clinical outcomes of pediatric inguinal hernia repairs operated by surgical residents

BACKGROUND

Inguinal hernia is one of the most common surgical diseases, and surgical residents perform inguinal hernia repairs during pediatric surgery rotation. The aims of this study were to examine the clinical outcomes of pediatric inguinal herniorrhaphy performed by surgical residents and to assess the suitability for surgical training.

METHODS

We extracted data on elective unilateral inguinal hernia repairs performed in children between 2014 and 2018. All eligible cases were divided into surgical resident and attending surgeon groups according to the operator. We reviewed medical records retrospectively and compared some clinical indicators between the 2 groups.

RESULTS

Of 294 eligible cases, 163 were performed by 37 surgical residents and 131 were performed by 4 attending surgeons. The median operative times in the resident and attending surgeon groups were 30 and 19 min, respectively. Operative time was statistically longer in the resident group (p < 0.001). The complication and recurrence rates in the resident and attending surgeon groups were 11.0% and 11.5%, and 0% and 0.8%, respectively (p = 1.000 and p = 0.466).

CONCLUSION

Inguinal hernia repairs could be properly performed by surgical trainees with the assistance of attending surgeons. Hernia operation might provide good opportunities for surgical residents to practice basic surgical skills.

Network meta-analysis of urinary retention and mortality after Lichtenstein repair of inguinal hernia under local, regional or general anaesthesia

BACKGROUND

Urinary retention and mortality after open repair of inguinal hernia may depend on the type of anaesthesia. The aim of this study was to investigate possible differences in urinary retention and mortality in adults after Lichtenstein repair under different types of anaesthesia.

METHODS

Systematic searches were conducted in the Cochrane, PubMed and Embase databases, with the last search on 1 August 2018. Eligible studies included adult patients having elective unilateral inguinal hernia repair by the Lichtenstein technique under local, regional or general anaesthesia. Outcomes were urinary retention and mortality, which were compared between the three types of anaesthesia using meta-analyses and a network meta-analysis.

RESULTS

In total, 53 studies covering 11 683 patients were included. Crude rates of urinary retention were 0·1 (95 per cent c.i. 0 to 0·2) per cent for local anaesthesia, 8·6 (6·6 to 10·5) per cent for regional anaesthesia and 1·4 (0·6 to 2·2) per cent for general anaesthesia. No death related to the type of anaesthesia was reported. The network meta-analysis showed a higher risk of urinary retention after both regional (odds ratio (OR) 15·73, 95 per cent c.i. 5·85 to 42·32; P < 0·001) and general (OR 4·07, 1·07 to 15·48; P = 0·040) anaesthesia compared with local anaesthesia, and a higher risk after regional compared with general anaesthesia (OR 3·87, 1·10 to 13·60; P = 0·035). Meta-analyses showed a higher risk of urinary retention after regional compared with local anaesthesia (P < 0·001), but no difference between general and local anaesthesia (P = 0·08).

CONCLUSION

Local or general anaesthesia had significantly lower risks of urinary retention than regional anaesthesia. Differences in mortality could not be assessed as there were no deaths after elective Lichtenstein repair. Registration number: CRD42018087115 ( https://www.crd.york.ac.uk/prospero).
