ABSTRACT
BACKGROUND: Portal vein thrombosis is a potentially devastating complication following pediatric liver transplantation. In rare instances of complete portomesenteric thrombosis, cavoportal hemitransposition may provide graft inflow. Here we describe long-term results following a case of pediatric cavoportal hemitransposition during liver transplantation and review the current pediatric literature. METHODS: A 9-month-old female with a history of biliary atresia and failed Kasai portoenterostomy underwent living donor liver transplantation, which was complicated by portomesenteric venous thrombosis. The patient underwent retransplantation with cavoportal hemitransposition on postoperative day 12. OUTCOME: The patient recovered without further complication, and 10 years later, she continues to do well, with normal graft function and no clinical sequelae of portal hypertension. CT scan with 3-D vascular reconstruction demonstrated recanalization of the splanchnic system, with systemic drainage to the inferior vena cava via an inferior mesenteric vein shunt. The cavoportal anastomosis remains patent with hepatopetal flow. Of the 12 previously reported cases of pediatric cavoportal hemitransposition as portal inflow in liver transplantation, this is the longest-known follow-up with a viable allograft. Notably, sequelae of portal hypertension were also rare in the 12 previously reported cases, with no cases of long-term renal dysfunction, lower extremity edema, or ascites. CONCLUSIONS: Long-term survival beyond 10 years with normal graft function is feasible following pediatric cavoportal hemitransposition. Complications related to portal hypertension were generally short-lived, likely due to the development of robust collateral circulation. Additional reports of long-term outcomes are necessary to facilitate informed decision making when considering pediatric cavoportal hemitransposition for liver graft inflow.

BACKGROUND: Inaccuracy of clinical staging renders management of clinical T2 N0 M0 (cT2 N0 M0) esophageal cancer difficult. When an underlying advanced-stage disease is understaged to cT2 N0 M0, patients miss the opportunity to gain the potential benefits of neoadjuvant therapy. This study aimed to identify preoperative factors that predict underlying advanced-stage esophageal cancer. METHODS: From 2000 to 2020, 1579 patients with esophageal cancer underwent esophagectomy. Sixty patients who underwent upfront surgery for cT2 N0 M0 esophageal cancer were included in this study. The median age was 62.5 years, and 78% (n = 47) of these patients were male. Radiologic, clinical, and endoscopic factors were evaluated as preoperative markers. The Fisher exact and the Wilcoxon rank sum tests were used for categoric and continuous variables, respectively. Random forest classification was used to identify preoperative factors for predicting upstaging and downstaging. RESULTS: Of the 60 patients, 8 (13%) were found to have pathologic T2 N0 M0 esophageal cancer. Sixteen (27%) patients had cancer that was pathologically downstaged, and 36 (60%) had upstaged disease. Seven (19%) patients had upstaged cancer on the basis of the pathologic T stage, 14 (39%) had upstaging on the basis of the pathologic N stage, and 15 (42%) had upstaging on the basis of both T and N stages. Dysphagia (P = .003) and tumor maximum standardized uptake value (P = .048) were predictors of upstaging, with a combined predictive value of up to 75%. CONCLUSIONS: The presence of dysphagia and of high maximum standardized uptake value (≥5) of the tumor is predictive of more advanced underlying disease for patients with cT2 N0 M0 esophageal cancer, and these patients should be considered for neoadjuvant therapy.

BACKGROUND: Open approaches for esophagectomy are often still useful; of these, left thoracoabdominal esophagectomy (TAE) is poorly understood and often criticized. Hence, we examined TAE's worldwide utilization, survival, and present-day use and outcomes at our institution compared with contemporary national averages. METHODS: The Worldwide Esophageal Cancer Collaboration database includes 8854 patients who underwent esophagectomy for cancer between 2005 and 2014, a period when TAE was our center's most common approach. Two propensity score-matched models were constructed: worldwide TAE vs worldwide non-TAE (751 matched pairs); and our high-volume center TAE vs worldwide non-TAE (273 matched pairs). All-cause mortality was compared between matched groups. Institutional TAE data from 2017 to 2021 were assessed for present-day use and outcomes. RESULTS: Worldwide, propensity score-matched patients undergoing TAE had a median of 20 lymph nodes resected vs 17 after non-TAE (P < .0001). Five-year survival was 34% for worldwide TAE vs 42% for worldwide non-TAE groups (P = .04). Three-year matched survival was 52% for high-volume TAE compared with 54% for worldwide non-TAE groups (P = .1). From 2017 to 2021 at our institution, 90 (26%) of 346 esophagectomies were performed by TAE. Pneumonia developed in 5 patients (5.6%), with 88 patients (98%) alive at 30 days, comparable to contemporary averages of The Society of Thoracic Surgeons. CONCLUSIONS: When it is performed as the primary approach in high volumes, TAE can have comparable outcomes to non-TAE with low morbidity. At present, we find that TAE is most useful in patients with truncal obesity, prior abdominal operations, and locally advanced cardia tumors with potential for variable extent of resection.

Bilateral transverse thoracosternotomy, or "clamshell" thoracotomy, can be complicated by dehiscence. A 65-year-old male underwent lung transplantation via clamshell thoracotomy, with subsequent sternal dehiscence on postoperative day 11. Upon repair, the previous sternal wires had pulled through, so a Sternal Talon connected to a Recon Talon was utilized to re-approximate the inferior sternum. On follow-up at 3 months, the patient recovered well. Use of the Sternal Talon provides an effective technique for repairing transverse sternal dehiscence.
ABSTRACT
BACKGROUND: Type I achalasia comprises 20% of achalasia and has nearly absent esophageal motor activity. Concerns that fundoplication decreases the effectiveness of Heller myotomy in these patients has increased adoption of peroral endoscopic myotomy (POEM). Hence, we compared outcomes after Heller myotomy with Dor fundoplication vs POEM. METHODS: From 2005 to 2020, 150 patients with type I achalasia underwent primary surgical myotomy (117 Heller myotomy, 33 POEM). Patient demographics, prior treatments, timed barium esophagrams, Eckardt scores, and reinterventions were assessed between the 2 groups. Median follow-up was 5 years for Heller myotomy and 2.5 years for POEM. RESULTS: The Heller myotomy group was younger, had fewer comorbidities, and lower body mass index vs POEM. Risk-adjusted models demonstrated clinical success (Eckardt ≤3) in 83% of Heller myotomies and 87% of POEMs at 3 years; longitudinal complete timed barium esophagram emptying and reintervention were also similar. An abnormal pH test result was documented in 10% (6 of 60) after Heller myotomy and in 45% (10 of 22) after POEM (P < .001). CONCLUSIONS: Despite nearly absent esophageal contractility, Heller myotomy with Dor fundoplication and POEM result in similar long-term symptom relief, esophageal emptying, and occurrence of reintervention in patients with type I achalasia. There is decreased esophageal acid exposure with the addition of a fundoplication, without compromised esophageal drainage, allaying fears of a detrimental effect of a fundoplication. Hence, choice of procedure may be personalized based on patient characteristics and esophageal morphology and not solely on manometric subtype.

OBJECTIVES: We hypothesized that emergency complications related to asymptomatic paraconduit hernias may occur less often than generally believed. Therefore, we assessed the occurrence and timing of paraconduit hernia diagnosis after esophagectomy, as well as outcomes of these asymptomatic patients managed with a watch-and-wait approach. METHODS: From 2006 to 2021, 1214 patients underwent esophagectomy with reconstruction at the Cleveland Clinic. Among these patients, computed tomography scans were reviewed to identify paraconduit hernias. Medical records were reviewed for timing of hernia diagnosis, hernia characteristics, and patient symptoms, complications, and management. During this period, patients with asymptomatic paraconduit hernias were typically managed nonoperatively. RESULTS: Paraconduit hernias were identified in 37 patients. Of these, 31 (84%) had a pre-esophagectomy hiatal hernia. Twenty-one hernias (57%) contained colon, 7 hernias (19%) contained pancreas, and 9 hernias (24%) contained multiple organs. Estimated prevalence of paraconduit hernia was 3.3% at 3 years and 7.7% at 10 years. Seven patients (19%) had symptoms, 4 of whom were repaired electively, with 2 currently awaiting repairs. No patient with a paraconduit hernia experienced an acute complication that required emergency intervention. CONCLUSIONS: The risk of paraconduit hernia increases with time, suggesting that long-term symptom surveillance is reasonable. Emergency complications as a result of asymptomatic paraconduit hernias are rare. A small number of patients will experience hernia-related symptoms, sometimes years after hernia diagnosis. Our findings suggest that observation of asymptomatic paraconduit hernias (watch and wait) may be considered, with repair considered electively in patients with persistent symptoms.

OBJECTIVE: Currently, there is no validated patient-reported outcome measure (PROM) applicable to all esophageal diseases. Our objective was to create a psychometrically robust, validated universal esophageal PROM that can also objectively assess patients' quality of life (QoL). METHODS: The pilot PROM constructed based on expert opinions, literature review, and previous unpublished institutional research had 27 items covering 8 domains. It was completed by 30 patients in the outpatient clinic followed by a structured debriefing interview, which allowed for refining the PROM. The final PROM: Cleveland Clinic Esophageal Questionnaire (CEQ) included 34 items across 6 domains (Dysphagia, Eating, Pain, Reflux & Regurgitation, Dyspepsia, Dumping), each accompanied by a corresponding QoL component. Further psychometric assessment of the PROM was conducted by evaluating (1) acceptability, (2) construct validity, (3) reliability, and (4) responsiveness. RESULTS: Five hundred forty-six unique patients (median 63.7 years [54.3-71.7], 53% male [287], 86% White) completed CEQ at >90% completion within 5 minutes. Construct validity was demonstrated by differentiating scores across esophageal cancer (n = 146), achalasia (n = 170), hiatal hernia (n = 160), and other diagnoses (n = 70). Internal reliability (Cronbach alpha 0.83-0.89), and test-retest reliability (intraclass correlation coefficients 0.63-0.85) were strong. Responsiveness was demonstrated through CEQ domains improving for 53 patients who underwent surgery for achalasia or hiatal hernia (Cohen d 0.86-2.59). CONCLUSIONS: We have constructed a psychometrically robust, universal esophageal PROM that allows concise, consistent, objective quantification of symptoms and their effect on the patient. The CEQ is valuable in prognostication and tracking of longitudinal outcomes in both benign and malignant esophageal diseases.

OBJECTIVE: Spread through air spaces (STAS) is a new histologic feature of invasion of non-small cell lung cancer that lacks sensitivity and specificity on frozen sections and is associated with higher recurrence and worse survival with sublobar resections. Our objective is to identify preoperative characteristics that are predictive of STAS to guide operative decisions. METHODS: From January 2018 through December 2021, 439 cT1-3N0 M0 patients with non-small cell lung cancer and a median age of 68 years, 255 (58%) women, who underwent primary surgery at our institution were included. Patients who received neoadjuvant therapy and whose STAS status was not documented were excluded. Age, sex, smoking status, tumor size, ground-glass opacities, maximum standardized uptake values, and molecular markers on preoperative biopsy were evaluated as preoperative markers. Comparisons between groups were conducted using standardized mean differences and random forest classification was used for prediction modeling. RESULTS: Of the 439 patients, 177 had at least 1 STAS-positive tumor, and 262 had no STAS-positive tumors. Overall, 179 STAS tumors and 293 non-STAS tumors were evaluated. Younger age (50 years or younger), solid tumor, size ≥2 cm, and maximum standardized uptake value ≥2.5 were independently predictive of STAS with prediction probabilities of 50%, 40%, 38%, and 40%, respectively. STAS tumors were more likely to harbor KRAS mutations and be PD-L1 negative. CONCLUSIONS: Young age (50 years or younger), larger (≥2 cm) solid tumors, high maximum standardized uptake values, and presence of KRAS mutation, are risk factors for STAS and can be considered for lobectomy. Smoking status and gender are still controversial risk factors for STAS.
ABSTRACT
BACKGROUND: Esophageal morphology in achalasia is thought to affect outcomes, with "end-stage" sigmoidal morphology faring poorly; however, evaluation of morphology's role in outcomes has been limited by lack of objective characterization. Hence, the goals of this study were twofold: characterize the variability of timed barium esophagram (TBE) interpretation and evaluate an objective classification of TBE tortuosity: length-to-height ratio (LHR). We hypothesized that the esophagus must elongate to become sigmoidal such that sigmoidal morphology would demonstrate a larger LHR. METHODS: Ninety pre-operative TBEs were selected from an institutional database. Esophageal morphology was categorized as straight, intermediate, or sigmoidal. Esophageal length was measured by a mid-lumen line from the aortic knob to the esophagogastric junction on TBE; height was measured vertically from the aortic knob to the level of the esophagogastric junction. The length divided by the height generated the LHR. Descriptive statistics and frequency of expert agreement were calculated. Median LHR was compared between consensus morphologies. A receiver operating characteristic (ROC) determined the optimal LHR for sigmoidal vs non-sigmoidal characterization. RESULTS: From a total of 90 pre-operative TBEs, expert consensus morphology was reached in 56 (62.2%) cases. Pairs of experts agreed on morphology in 62-74% of TBEs, with all three experts agreeing on 46.7-48.9% of cases. Median LHR between expert consensus morphologies was 1.03, 1.09, and 1.24 for straight, intermediate, and sigmoidal morphologies, respectively (p < 0.001). ROC demonstrated that an LHR cutoff of 1.13 was 100% sensitive and 95% specific (AUC 0.99) for ruling out sigmoidal morphology. CONCLUSION: These findings confirm our anecdotal experience that subjective morphology interpretation is variable, even between experts at a high-volume center. LHR provides an objective method for classification, allowing us to overcome the limitations of inter-observer variability, thus paving the way for future study of the role of morphology in achalasia outcomes.

Background: Diaphragmatic hernias with strangulated contents are a surgical challenge. Thoracoabdominal incisions are commonly used for a variety of thoracic and vascular cases, although rarely used for diaphragmatic hernias, which are typically repaired with laparotomy, thoracotomy, or minimally invasive approaches. Case report: We present the unique case of a 60-year-old, critically ill unstable patient with severe heart failure with a reduced ejection fraction (15-25%) and severe valve disease presenting with a left-sided diaphragmatic hernia containing strangulated small intestine and requiring urgent surgical exploration. This was safely and efficiently repaired via a thoracoabdominal approach at the index surgery, with intestines left in discontinuity and placement of temporary chest and abdominal closure. At the second planned operation, good continuity was successfully restored. Results: The patient had early extubation, gradual diet advancement with full recovery, and discharge home on postoperative day 17. Conclusion: A thoracoabdominal incision can safely be used in large strangulated diaphragmatic hernias, including in critically unstable patients. This approach provides rapid access to both the chest and abdomen with excellent, speedy, and safe exposure, which can save a life in extreme conditions.
ABSTRACT
BACKGROUND: Laparoscopic liver resection (LLR) involves a difficult learning curve, for which multiple difficulty scores have been proposed to assist with safe adaptation. The IWATE Criteria is a 4-level difficulty score shown to correlate with conversion to open surgery, estimated blood loss (EBL), and operative time in Japanese and French cohorts. We set out to validate the IWATE Criteria in a North American cohort, describe the evolution of our LLR program, and analyze the IWATE Criteria's ability to predict conversion to open surgery. METHODS: Patients that underwent LLR between January 2006 and December 2019 were selected from a prospectively maintained database. Difficulty outcomes, including conversion to open surgery, EBL, operative time, and post-operative complications were analyzed according to IWATE difficulty level, both overall and between chronological eras. The IWATE Criteria's ability to predict conversion to open surgery was assessed with a receiver operating characteristic (ROC) analysis. RESULTS: A total of 426 patients met inclusion criteria. Operative time, EBL, and conversion to open surgery increased in concordance with low to advanced IWATE difficulty. ROC analysis for conversion to open surgery demonstrated an overall area under the curve (AUC) of 0.694. Predictive performance was superior during the first two eras, with AUCs of 0.771 and 0.775; predictive value decreased as the LLR program gained experience, with AUCs of 0.708 and 0.551 for eras three and four. CONCLUSIONS: This study validated the IWATE Criteria in a North American population distinct from previous Japanese and French cohorts, based on its correlation with operative time, EBL, and conversion to open surgery. The IWATE Criteria may be of utility for identification of LLR cases appropriate for surgeon experience, as well as determination of laparoscopic feasibility. Interval difficulty score recalibration may be warranted as surgeon perception of difficulty evolves.

OBJECTIVES: To determine the prevalence of sleep disturbances in orthopaedic trauma patients 3 months following surgery and to identify any subset(s) of patients at high risk for prolonged sleep disturbance. DESIGN: Prospective cohort. SETTING: Level 1 Trauma Center. PATIENT/PARTICIPANTS: All patients at an orthopaedic trauma clinic from May 3, 2016 to Feb 23, 2017. MAIN OUTCOME MEASUREMENTS: Baseline patient Pittsburgh Sleep Questionnaire (PSQI) and Insomnia Severity Index (ISI) scores compared to PSQI and ISI scores 3-months postoperatively. Both gender and age stratified data analyses were performed. RESULTS: Sixty-six patients met our inclusion criteria and completed both baseline and 3-month surveys. There were 44 males and 22 females. There was a significant increase in PSQI and ISI scores from baseline to 3 months across all patients. Further analysis revealed significant increases from baseline to 3 months in both PSQI and ISI scores for female patients but not male patients. There was a significant difference from baseline to 3 months in patients 50 years old and under but not for patients above 50 years old. No patients required revision surgery in the first 3 months. CONCLUSIONS: More than half of all patients reported continued sleep disturbance 3 months postoperatively. Females are at particularly increased risk for sleep disturbance. These findings demonstrate that sleep disturbances merit attention in the early stages of the postoperative recovery process. LEVEL OF EVIDENCE: Therapeutic Level II.
