RESUMO
BACKGROUND: Resident operative involvement is an integral aspect of general surgery residency training. However, current data examining the effect of resident autonomy on perioperative outcomes remain limited. METHODS: Patient and operator-specific data were collected from 344 adult laparoscopic cholecystectomies at a tertiary academic institution and its regional affiliates between 2018 and 2019. Multivariate modeling compared postoperative outcomes between cases completed with or without resident involvement and its effect modification by resident seniority and autonomy per Zwisch scale. Outcomes include 30-day postoperative complications, hospital readmission rate, and operative time. RESULTS: Multivariate analysis revealed resident involvement in laparoscopic cholecystectomy did not significantly change odds of 30-day postoperative complications (OR 2.52, p = 0.185, 95% CI 0.64-9.92) or hospital readmission (OR 1.61, p = 0.538, 95% CI 0.36-7.23). Operative time is significantly increased compared to faculty-only cases (IRR 1.37, p < 0.001, 95% CI 1.26-1.48). While accounting for case difficulty and resident performance evaluated by SIMPL criteria, stratification by resident autonomy measured by Zwisch scale or seniority reveal no effect modification on 30-day postoperative complications, readmissions, or operative time. The effect of resident involvement on longer relative rates of operative time loses its significance in supervision-only cases (IRR 1.18, p = 0.069, 95% CI 0.99-1.41). CONCLUSION: While resident involvement and autonomy are associated with significantly longer operative times in laparoscopic cholecystectomy, their lack of significant effect on postoperative outcomes argues strongly for continued resident involvement and supervised operative independence.

INTRODUCTION: Collecting accurate operative details remains a limitation of surgical research. Surgeon-entered data in clinical registries offers one solution, but natural language processing (NLP) has emerged as a modality for automating manual chart review (MCR). This study aims to compare the accuracy and efficiency of NLP and MCR with a surgeon-entered, prospective registry data in determining the rate of gross bile spillage (GBS) during cholecystectomy. METHODS: Bile spillage rates were abstracted from an institutional, surgeon-entered clinical registry from July 2018 to January 2019. These rates were compared to those documented in the electronic medical record (EMR) using NLP and MCR to determine the sensitivity, specificity, and efficiency of each approach. RESULTS: Of the 782 registry entries, 191 cases (24.4%) had surgeon-reported bile spillage. MCR identified bile spillage in 121 cases (15.6%); however, bile spillage information was either missing or ambiguous in 454 cases (58.1%). NLP identified 99 cases (12.7%) of bile spillage. Data abstraction times for the registry, NLP, and MCR were 3 min, 5 min, and 12 h, respectively. When compared to the registry, MCR was 45% sensitive and 94% specific, while NLP was 27.2% sensitive and 92% specific for detecting bile spillage. These differences were significant (X2 = 19.446, P = < 0.001). CONCLUSION: Operative details, such as GBS, may not be abstracted by NLP or MCR if not clearly documented in the EMR. Clinical registries capture operative details, but they rely on surgeons to input the data.

Importance: Urinary catheters are commonly placed during laparoscopic inguinal hernia repair as a presumed protection against postoperative urinary retention (PUR), one of the most common complications following this operation. Data from randomized clinical trials evaluating the effect of catheters on PUR are lacking. Objective: To investigate the effect of intraoperative catheters on PUR after laparoscopic inguinal hernia repair. Design, Setting, and Participants: This 2-arm registry-based single-blinded randomized clinical trial was conducted at 6 academic and community hospitals in the US from March 2019 to March 2021 with a 30-day follow-up period following surgery. All patients who presented with inguinal hernias were assessed for eligibility, 534 in total. Inclusion criteria were adult patients undergoing laparoscopic, elective, unilateral, or bilateral inguinal hernia repair. Exclusion criteria were inability to tolerate general anesthesia and failure to understand and sign the written consent form. A total of 43 patients were excluded prior to intervention. Interventions: Patients in the treatment arm had placement of a urinary catheter after induction of general anesthesia and removal at the end of procedure. Those in the control arm had no urinary catheter placement. Main Outcomes and Measures: PUR rate. Results: Of the 491 patients enrolled, 241 were randomized to catheter placement, and 250 were randomized to no catheter placement. The median (IQR) age was 61 (51-68) years, and 465 participants (94.7%) were male. Overall, 44 patients (9.1%) developed PUR. There was no difference in the rate of PUR between the catheter and no-catheter groups (23 patients [9.6%] vs 21 patients [8.5%], respectively; P = .79). There were no intraoperative bladder injuries. In the catheter group, there was 1 incident of postoperative urethral trauma in a patient who presented to the emergency department with PUR leading to a suprapubic catheter placement. Conclusions and Relevance: Intraoperative urinary catheters did not reduce the risk of PUR after laparoscopic inguinal hernia repair. While their use did not appear to be associated with a high rate of iatrogenic complications, there may be a low rate of catastrophic complications. In patients who voided urine preoperatively, catheter placement did not appear to confer any advantage and thus their use may be reconsidered. Trial Registration: ClinicalTrials.gov Identifier: NCT03835351.

BACKGROUND: Chronic postoperative inguinodynia is a challenging long-term complication after inguinal hernia repair. Surgery may be an option for patients who are refractory to non-operative measures. We aim to evaluate the short-term outcomes of surgical treatment for chronic inguinodynia at our institution. METHODS: Consecutive patients undergoing surgical treatment for chronic groin pain were identified in a prospectively maintained database. Outcomes included operative details, intra- and postoperative complications, pain scores, and patient satisfaction. RESULTS: 29 patients were included in the study. All patients were refractory to multimodal pain management. The median pain score on presentation was 8 (IQR 7-10), and after a median follow-up of 6 months (IQR 4-11), there was a statistically significant reduction in pain scores (median 2, IQR 2-6, pâ¯<â¯0.001). Fifty-five percent of patient were pain free or almost pain free and 93 percent reported they would undergo the same operation again. CONCLUSIONS: Chronic groin pain is a complex problem with no universal solution. In our experience, surgical treatment significantly decreased short-term pain scores.

Postoperative leaks after laparoscopic Roux-en-Y gastric bypass (LRYGB) are a source of morbidity and mortality. Any intervention that would decrease leak rates after LRYGB would be useful. This investigation tested the hypothesis that postoperative leak rates are lower after LRYGB with the routine use of intraoperative endoscopy (EN). Consecutive patients who underwent LRYGB were included. Intraoperative leak testing with air and methylene blue through an orogastric tube (OG) was used in the first 200 patients. Intraoperative endoscopy was used after the first 200 patients. There were 400 patients in this study. Preoperative demographics did not differ between groups. The intraoperative leak rate of the EN group was double the OG group (8 vs 4%; P = not significant), although the difference was not statistically significant. The OG group had a postoperative leak rate of 4 per cent with a mortality rate of 1 per cent. The EN group had a postoperative leak rate of 0.5 per cent with a mortality rate of 0 per cent. The difference in leak rates was statistically significant (P < 0.04). Despite the issues of learning curve, EN demonstrates more intraoperative leaks than OG, indicating EN may be a more sensitive test than OG. Routine use of EN is associated with less postoperative leaks after LRYGB.

The complications of spinal cord injury are exaggerated with obesity, and create complex medical and socioeconomic issues. Despite the well-documented advantages of bariatric surgery in reducing the morbidity of obesity, this option has not been routinely offered to obese patients with spinal cord injuries. We describe the first case of a morbidly obese male with a spinal cord injury who underwent a successful Roux-en-Y gastric bypass.

BACKGROUND: A fine-needle aspiration biopsy (FNAB) specimen of a thyroid nodule with a predominance of Hürthle cells usually is indicative of a Hürthle cell neoplasm, but it also may occur with nonneoplastic disease. METHODS: A prospective nodular thyroid disease database was used to identify patients with a FNAB specimen consisting of a predominance of Hürthle cells. Clinical factors were investigated and FNAB specimens were examined in a blinded fashion by a single cytopathologist to determine if there were specific factors that could be used to distinguish nonneoplastic from neoplastic disease. RESULTS: Of the 738 patients with nodular thyroid disease, 622 had a FNAB specimen. The FNAB specimen was interpreted as consistent with a Hürthle cell neoplasm in 45 (7%) patients, 7 (16%) with carcinoma, 21 (47%) with adenoma, 12 (27%) with adenomatous hyperplasia, and 5 (11%) with thyroiditis. Extensive cellularity and absent colloid were associated with neoplastic disease (P < .05). No cytologic feature reliably excluded neoplastic disease (P > .05). No significant differences in age (x +/- SD) (51 +/- 17 vs 54 +/- 17 y), sex (female/male ratio, 6/1 vs 15/2), nodule size (3.9 +/- 1.9 vs 3.4 +/- 2.0 cm), weight of excised thyroid tissue (42 +/- 27 vs 33 +/- 30 g), or functional status of the thyroid gland was observed between patients with neoplastic (n = 28, 62%) versus nonneoplastic (n = 17, 38%) disease. CONCLUSIONS: Neoplastic disease accounts for two thirds of the pathology in patients with a predominance of Hürthle cells on FNAB specimen and neither clinical nor cytologic features reliably exclude Hürthle cell adenoma or carcinoma. As a result, thyroidectomy is recommended for all patients with a thyroid nodule and a predominance of Hürthle cells on FNAB specimen.

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.

PURPOSE: A fecalith is a fecal concretion that can obstruct the appendix leading to acute appendicitis. We hypothesized that the presence of a fecalith would lead to an earlier appendiceal perforation. METHODS: Between January 2001 and December 2005, the charts of all patients younger than 18 years old who underwent appendectomy at our institution were reviewed. Duration of symptoms and timing between presentation and operation were noted along with radiologic, operative, and pathologic findings. RESULTS: There were 388 patients who met the study criteria. A fecalith was present in 31% of patients (n = 121). The appendix was perforated in 57% of patients who had a fecalith vs 36% in patients without a fecalith (P < .001). The overall rate of interval appendectomies was 12%. A fecalith was present on the initial radiologic studies of 36% of the patients who had interval appendectomies, and the appendix was perforated significantly sooner in these patients when compared to those without a fecalith (91 vs 150 hours; P = .036). CONCLUSION: The presence of fecalith is associated with earlier and higher rates of appendiceal perforation in pediatric patients with acute appendicitis. An expedient appendectomy should therefore be performed in the pediatric patient with a radiologic evidence of fecalith.

INTRODUCTION: Community hospitals commonly obtain computed tomographic (CT) imaging of pediatric trauma patients before triaging to a level I pediatric trauma center (PTC). This practice potentially increases radiation exposure when imaging must be duplicated after transfer. METHODS: A retrospective review of our level 1 PTC registry from January 1, 2004, to December 31, 2006, was conducted. Level I and II trauma patients were grouped based on whether they had undergone outside CT examination (head and/or abdomen) at a referring hospital (group 1) or received initial CT examination at our institution (group 2). Subgroups were analyzed based on whether duplicate CT examination was required at our PTC (Fischer's Exact test). RESULTS: A duplicate CT scan (within 4 hours of transfer) was required in 91% (30/33) of group 1 transfer patients, whereas no group 2 patient required a duplicate scan (0/55; P < .0001). There was no significant difference within the groups for weight, age, or intensive care unit length of stay. CONCLUSION: A significant number of pediatric trauma patients who receive CT scans at referring hospitals before transfer to our level I PTC require duplicate scans of the same anatomical field(s) after transfer, exposing them to increase potential clinical risk and cost.

PURPOSE: We studied the effects of total parenteral nutrition (TPN)-associated hyperglycemia on the clinical outcome in premature septic infants in the neonatal intensive care unit. METHODS: The charts of all premature infants weighing less than 1500 g upon admission to the neonatal intensive care unit between January 1, 2002, and December 31, 2002, with sepsis, ventilator dependence, and feeding intolerance were studied. Maximum serum glucose concentrations were compared with duration of TPN, mechanical ventilation, hospital length of stay, and survival using Pearson regression analysis and Student's t test. RESULTS: Thirty-seven patients met the search criteria. The average caloric intake for all infants at the time of blood culture-proven sepsis was 83 +/- 19 kcal/kg per day. The maximum serum glucose concentration (milligrams per deciliter) after having positive blood cultures (sepsis) was positively correlated with the duration of TPN (r = 0.45, P = .005), length of dependence on mechanical ventilation (r = 0.45, P = .006), and hospital length of stay (r = 0.36, P = .03). The average maximum serum glucose level was significantly higher in the nonsurviving infants (241 +/- 46 vs 141 +/- 48, P < .0001). CONCLUSION: Hyperglycemia correlated with prolonged ventilator dependency and increased hospital length of stay in premature septic infants. Avoidance of excessive nutrient delivery and tight glycemic control during periods of acute metabolic stress may improve outcome in this patient population.

BACKGROUND/PURPOSE: Serum C-reactive protein (CRP) levels reflect the severity of the metabolic response to injury in critically ill children. During this period, caloric overfeeding can increase complications and delay recovery. The authors hypothesized that by avoiding excessive caloric delivery, the effect of injury severity would be the major factor determining clinical outcome. METHODS: Twenty-eight surgical infants who had indirect calorimetry measurements while in the Neonatal Intensive Care Unit between August 2000 and January 2002 were studied. Serum CRP concentrations, mean energy expenditure (MEE), respiratory quotient (RQ), length of hospital stay (LOS), and caloric intake (I) at the time of indirect calorimetry were recorded. Data were analyzed using the Pearson product-moment correlation. RESULTS: Peak serum CRP was significantly correlated to LOS in all patients (r = 0.79, P < .0001). When net caloric balance (I-MEE) did not exceed 5 kcal/kg/d (n = 9), peak serum CRP was correlated positively with RQ (r = 0.66, P = .05). When I-MEE exceeded 5 kcal/kg/d (n = 19), the positive correlation of serum CRP with RQ was diminished (r = 0.23, P = .33). CONCLUSIONS: CRP-measured injury severity is a major determinant of clinical outcome in surgical infants. In addition, overfeeding causes additional RQ elevation.
