Resident involvement in laparoscopic procedures does not worsen clinical outcomes but may increase operative times and length of hospital stay.

BACKGROUND: Surgical procedures have a learning curve regarding the number of cases required for proficiency. Consequently, involvement of less experienced resident surgeons may impact patients and the healthcare system. This study examines basic and advanced laparoscopic procedures performed between 2010 and 2011 and evaluates the resident surgeon participation effect. METHODS: Basic laparoscopic procedures (BL), appendectomy (LA), cholecystectomy (LC), and advanced Nissen fundoplication (LN) were queried from the American College of Surgeons National Surgical Quality Improvement Program database. Cases were identified using Current Procedural Terminology codes. Analyses were performed using IBM SPSS Statistics v.22, α-level = 0.05. Multiple logistic regression was used, accounting for age, race, gender, admission status, wound classification, and ASA classification. RESULTS: In total, 71,819 surgeries were reviewed, 66,327 BL (37,636 LC and 28,691 LA) and 5492 LN. Median age was 48 years for LC and 37 years for LA. In sum, 72.2 % of LC and 49.5 % of LA patients were female. LN median age was 59 years, and 67.7 % of patients were female. For BL, resident involvement was not significantly associated with mortality, morbidity, and return to the OR. Readmission was not related to resident involvement in LC. In LA, resident-involved surgeries had increased readmission and longer OR time, but decreased LOS. In LC, resident involvement was associated with longer LOS and OR time. Resident involvement was not a significant factor in the odds of mortality, morbidity, return to OR, or readmission in LN. Surgeries involving residents had increased odds of having longer LOS, and of lengthier surgery time. CONCLUSIONS: We demonstrate resident involvement is safe and does not result in poorer patient outcomes. Readmissions and LOS were higher in BL, and operative times were longer in all surgeries. Resident operations do appear to have real consequences for patients and may impact the healthcare system financially.

Laparoscopic redo paraesophageal hernia repair with collis gastroplasty for shortened esophagus.

Esophageal shortening can be seen in patients with chronic inflammation associated with gastroesophageal reflux disease and paraesophageal hernias. During surgical treatment of these conditions, it is important to address the esophageal shortening during the operation for optimal outcomes. Ideally, 2.5-3 cm of tension-free intraabdominal esophagus is recommended. During this video, we show a redo paraesophageal hernia repair in which we were unable to achieve adequate esophageal lengthening despite extensive mediastinal dissection. We therefore proceeded with Collis gastroplasty with Toupet fundoplication.

Long-term outcomes of radiologic recurrence after paraesophageal hernia repair with mesh.

INTRODUCTION: Paraesophageal hernia (PEH) repair has a high radiologic recurrence rate, even with the use of biologic mesh as a prosthetic buttress to reinforce the primary crural repair. This review was done to evaluate outcomes after PEH repair with mesh. METHODS: A retrospective analysis was done of all patients who underwent PEH repair with mesh at our institution between December 2004 and March 2013. Patients were reviewed for evidence of recurrence on upper gastrointestinal studies (UGI). Time-specific, mesh-specific, and size-specific recurrence was analyzed as well as pre- and postoperative symptom scores. RESULTS: A total of 209 patients underwent PEH repair with mesh. Mean follow-up was 25 months (range 0-101). In all cases, an absorbable mesh was used (159 Alloderm, 35 BioA, 15 Strattice). One hundred and fifty-six (75 %) were 5 cm or larger. Of the patients, 166 (79 %) had UGIs available to review for radiologic recurrence. Total recurrence was 21 % (n = 35). No mesh erosions were seen. Recurrence rates increased over time from 16 % (n = 23) at 1 year up to 39 % after 5-year follow-up (n = 11). Recurrence rates were higher for large hernias (23 vs. 16 %). The median size of the recurrence was 4 cm (range 2-7 cm). Overall, patients showed significant improvement in their symptom scores. At long-term follow-up, heartburn had 70.6 % reduction (p < 0.05) and regurgitation had 76.5 % reduction (p < 0.05). There was no significant difference in postoperative symptom scores between patients with or without radiologic recurrence. CONCLUSIONS: In this study, PEH repair with mesh was safe and effective at controlling symptoms over the long term. Radiologic recurrence rate increased over time and was highest in patients with hernias >5 cm. Therefore, in our experience, PEH repair with mesh is a safe therapy and though radiologic recurrence does increase with time, symptom resolution is maintained.

Long-term patient outcomes after laparoscopic anti-reflux procedures.

BACKGROUND: Laparoscopic anti-reflux surgery with or without large hiatal hernia has been shown to have good short-term outcomes. However, limited data are available on long-term outcomes of greater than 5 years. The aim of this study is to review functional and symptomatic outcomes of anit-reflux surgery in a large tertiary referral medical center. METHODS: Two hundred ninety-seven patients who underwent anti-reflux surgery at the University of Nebraska Medical Center between 2002 and 2013 were included in this study. Patient data including pre- and post-operative studies and symptom questionnaires were prospectively collected and the database was used to analyze postoperative outcomes. RESULTS: A total of 297 Nissen fundoplications, 35 redo fundoplications and 22 Toupet procedures were performed. Mean BMI was 30.0 ± 6.2. The median follow-up was 70 (6-135) months. There were three reoperations (0.9 %) for recurrent symptoms. Mesh was used in 210 cases where hiatal hernia was larger than 2 cm. Median preoperative DeMeester score was 50.8 ± 46. There was a statistically significant improvement in composite heartburn score (83 % (CI 78.2, 87.7); p < 0.05), regurgitation (81.1 % (CI 76.1, 86.1); p < 0.05), and belching (63 % (CI 56.7, 69.3); p < 0.05). Atypical presentation such as pulmonary (e.g., aspiration (25.8 % (CI 20, 31.6), wheezing (20.3 % (CI 15, 25.6); p < 0.05), and throat symptoms (e.g., laryngitis 28 % (CI 22.1, 33.9); p < 0.05) also improved. Available radiographic studies for patients more than 3 years follow-up show an overall recurrence of 33.9 % (47.8 % in hiatal hernia > 5 cm repaired with mesh). Of those with recurrence, over 84 % were asymptomatic at follow-up. CONCLUSIONS: This study shows that patients had excellent symptom control and low rates of complications and reoperations in long-term follow-up. We found that typical gastro intestinal symptoms responded better compared with atypical symptoms in spite of clear evidence of reflux on preoperative studies. Hiatal hernia was very commonly seen in our patient population and long-term radiographic follow-up suggest that asymptomatic recurrence may be high but rarely requires any surgical intervention. Anti-reflux surgery with correction of hiatal hernia if present is safe and effective in long-term follow-up.
