Complications and Readmissions Associated with First Assistant Training Level Following Elective Bariatric Surgery

American society for metabolic and bariatric surgery: intra-operative care pathway for minimally invasive Roux-en-Y gastric bypass

BACKGROUND

Clinical care pathways help guide and provide structure to clinicians and providers to improve healthcare delivery and quality. The Quality Improvement and Patient Safety Committee (QIPS) of the American Society for Metabolic and Bariatric Surgery (ASMBS) has previously published care pathways for the performance of laparoscopic sleeve gastrectomy (LSG) and pre-operative care of patients undergoing Roux-en-Y gastric bypass (RYGB).

OBJECTIVE

This current RYGB care pathway was created to address intraoperative care, defined as care occurring on the day of surgery from the preoperative holding area, through the operating room, and into the postanesthesia care unit (PACU).

METHODS

PubMed queries were performed from January 2001 to December 2019 and reviewed according to Level of Evidence regarding specific key questions developed by the committee.

RESULTS

Evidence-based recommendations are made for care of patients undergoing RYGB including the pre-operative holding area, intra-operative management and performance of RYGB, and concurrent procedures.

CONCLUSIONS

This document may provide guidance based on recent evidence to bariatric surgeons and providers for the intra-operative care for minimally invasive RYGB.

Metabolic and Bariatric Surgeon Criteria-An International Experts' Consensus

PURPOSE

With the global epidemic of obesity, the importance of metabolic and bariatric surgery (MBS) is greater than ever before. Performing these surgeries requires academic training and the completion of a dedicated fellowship training program. This study aimed to develop guidelines based on expert consensus using a modified Delphi method to create the criteria for metabolic and bariatric surgeons that must be mastered before obtaining privileges to perform MBS.

METHODS

Eighty-nine recognized MBS surgeons from 42 countries participated in the Modified Delphi consensus to vote on 30 statements in two rounds. An agreement/disagreement among ≥ 70.0% of the experts was regarded to indicate a consensus.

RESULTS

Consensus was reached on 29 out of 30 statements. Most experts agreed that before getting privileges to perform MBS, surgeons must hold a general surgery degree and complete or have completed a dedicated fellowship training program. The experts agreed that the learning curves for the various operative procedures are approximately 25-50 operations for the LSG, 50-75 for the OAGB, and 75-100 for the RYGB. 93.1% of experts agreed that MBS surgeons should diligently record patients' data in their National or Global database.

CONCLUSION

MBS surgeons should have a degree in general surgery and have been enrolled in a dedicated fellowship training program with a structured curriculum. The learning curve of MBS procedures is procedure dependent. MBS surgeons must demonstrate proficiency in managing postoperative complications, collaborate within a multidisciplinary team, commit to a minimum 2-year patient follow-up, and actively engage in national and international MBS societies.

First Assistant In Bariatric Surgery: A Comparison Between Laparoscopic And Robotic Approaches: A 4-Year Analysis of the MBSAQIP Database (2016-2019)

PURPOSE

The first assistant (FA) plays an important role in the operating room for bariatric surgery. The aim of this study was to examine the relationship between the type of FA and operative time (OT) and postoperative outcomes comparing robotic and laparoscopic approaches in bariatric surgery.

METHODS AND MATERIALS

The Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) data for 2016-2019 was queried. Log-normal regression was performed to evaluate the association of FAs and OT variations within and between groups. We used logistic regression to examine the relationship between the type of FA and 30-day outcomes across all procedures and approaches.

RESULTS

A total of 691,789 patients who underwent robotic (R), and laparoscopic (L) sleeve gastrectomy (SG), Roux-en-Y gastric-bypass (RYGB), and duodenal switch (DS) were included. The percentage variation of OT was higher in the laparoscopic group (L-SG: 8.18%, L-RYGB: 9.88%, and L-DS: 15.00%) compared to the robotic group (R-SG: 2.43%, R-RYGB: 5.76%, and R-DS: 0.80%). There was not a significant difference in 30-day outcomes between laparoscopic and robotic approaches for the same procedures.

CONCLUSIONS

The FA was associated with a decreased variability in OT in the robotic cohort compared to the laparoscopic group with no significant difference in complication rates. These results suggest that the robotic approach may decrease the need for skilled FAs in bariatric procedures.

New findings regarding the influence of assistants on surgical outcomes in penile prosthesis implantation

Penile prosthesis implantation is the definitive treatment for refractory erectile dysfunction, yet exposure to this procedure during training of urology residents is often limited. To assess the effects of resident participation in penile prosthesis surgery, we compared surgical outcomes in a retrospective case series of 253 penile prosthesis surgeries by a single surgeon at the same institution between 2017 and 2020 with the assistance of either a registered nurse first assistant (RNFA) or a resident. Pertinent patient characteristics and surgical complications including device complications, surgical site infection, postoperative bleeding, iatrogenic injury, cardiovascular events, pulmonary events, and urinary retention were documented. Measured outcomes included operative time, Emergency Room (ER) visits, unplanned postoperative visits, pain medication refills, and surgical complications. Compared to RFNAs, resident-assisted penile prosthesis surgery was associated with significant increase in mean operative time (71.4 min vs. 87.9 min, p < 0.01) and postoperative ER visits (3.0% vs. 10.6%, p = 0.03) but not surgical complications (19.7% vs. 20.8%, OR 1.03, 95% CI [0.46 -2.30]) or other measured outcomes. Compared to a dedicated RFNA, Resident assistance increased operative time by approximately 17 min, but did not increase post-operative surgical complications, supporting the notion that resident assistance in these procedures may be appropriate as an integral part of training.

The Impact of Trainee Involvement on Outcomes in Metabolic and Bariatric Surgery

BACKGROUND

The number of bariatric operations performed in the USA rises annually. Trainee exposure to this field is necessary to ensure competency in future surgical generations. However, the safety of trainee involvement of these operations has been called into question.

OBJECTIVES

The aim of our study is to describe differences in outcomes between trainees and non-trainees as first assistants (FA) in sleeve gastrectomy (SG).

SETTING

The Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database METHODS: Patients from the MBSAQIP database who underwent primary SG from 2015 to 2020 were identified. Statistical analysis included two-tailed t-tests and χ2-tests to evaluate the impact of trainees (residents and fellows) compared to non-trainees on post-operative morbidity and operative time.

RESULTS

Of the 559,324 cases, 25.8% were performed with trainees as FA. Operative length was 27.9% longer in trainee cases. In the trainee group, there was a higher risk of conversion to open procedure (OR 1.32), readmission (OR 1.19), and specific complications (cardiac arrest, myocardial infarction, progressive renal insufficiency, pulmonary embolism, sepsis, transfusion, intubation, UTI, VTE, ICU admission, and reintervention), though overall rates were < 1% in each group. Non-trainees had a higher rate of septic shock (OR 1.4). No significant difference was seen in all other perioperative outcomes.

CONCLUSION

Trainee involvement in SG leads to longer operative times without a clinically significant increase in morbidity and mortality. Such findings should be used to counsel patients and shape expectations for surgeons and hospitals. A focused bariatric surgery trainee curriculum may lessen this gap.

Neurosurgeons Deliver Similar Quality Care Regardless of First Assistant Type: Resident Physician versus Nonphysician Surgical Assistant

OBJECTIVE

There are limited data evaluating the outcomes of attending neurosurgeons with different types of first assistants. This study considers a common neurosurgical procedure (single-level, posterior-only lumbar fusion surgery) and examines whether attending surgeons deliver equal patient outcomes, regardless of the type of first assistant (resident physician vs. nonphysician surgical assistant [NPSA]), among otherwise exact-matched patients.

METHODS

The authors retrospectively analyzed 3395 adult patients undergoing single-level, posterior-only lumbar fusion at a single academic medical center. Primary outcomes included readmissions, emergency department visits, reoperation, and mortality within 30 and 90 days after surgery. Secondary outcome measures included discharge disposition, length of stay, and length of surgery. Coarsened exact matching was used to match patients on key demographics and baseline characteristics known to independently affect neurosurgical outcomes.

RESULTS

Among exact-matched patients (n = 1402), there was no significant difference in adverse postsurgical events (readmission, emergency department visits, reoperation, or mortality) within 30 days or 90 days of the index operation between patients who had resident physicians and those who had NPSAs as first assistants. Patients who had resident physicians as first assistants demonstrated a longer length of stay (mean: 100.0 vs. 87.4 hours, P < 0.001) and a shorter duration of surgery (mean: 187.4 vs. 213.8 minutes, P < 0.001). There was no significant difference between the two groups in the percentage of patients discharged home.

CONCLUSIONS

For single-level posterior spinal fusion, in the setting described, there are no differences in short-term patient outcomes delivered by attending surgeons assisted by resident physicians versus NPSAs.

Does the experience of the first assistant affect organ injuries in laparoscopic hysterectomy for benign diseases?

PURPOSE

This study sought to explore whether the experience level of the first assistant surgeon influences perioperative organ injuries (ureteral, bladder, and intestinal injuries) in patients undergoing total laparoscopic hysterectomy (TLH) for benign diseases. We defined an experienced surgeon as a surgeon certified by the Skill Qualification Committee of the Japan Society of Gynecologic and Obstetric Endoscopy and Minimally Invasive Therapy or a surgeon with equivalent surgical skills.

METHODS

We reviewed our surgical registry database of TLH for benign indications between 2014 and 2020 and only selected cases performed by an experienced primary surgeon. Patients were divided into two groups based on the experience level of the first assistant. Inverse probability of treatment weighting by propensity score, which was adjusted for patient and procedure characteristics, was used to examine differences in perioperative organ injuries according to the experience level of the first assistant.

RESULTS

Among 1682 patients who underwent TLH, 18 organ injuries were found (0.83%). In the propensity score inverse probability of treatment weighting models, less experience of the first assistant had no significant impact on the occurrence of perioperative organ injuries (p = 0.348).

CONCLUSION

In TLH for benign indications at our hospital, given an experienced primary surgeon, the inclusion of a less experienced first assistant does not negatively affect the occurrence of perioperative organ injuries.
