Importance The Surgery as Needed for Oesophageal Cancer (SANO) trial introduced active surveillance as a noninferior alternative to esophagectomy for patients with esophageal cancer who achieve a clinical complete response (cCR) after neoadjuvant chemoradiation (nCRT). However, concerns remain about recurrence risk, long-term survival, and quality-of-life trade-offs with organ-preserving strategies. Objective To evaluate the long-term comparative effectiveness of active surveillance vs standard esophagectomy in patients with cCR following nCRT for locally advanced esophageal cancer, using updated data from the SANO trial. Design, Setting, and Participants This decision analytical model used Markov modeling and probabilities and utility inputs derived from the SANO trial and existing literature. The base case was a 60-year-old male with good functional status and cT3N1M0 esophageal cancer achieving cCR after nCRT. Exposures Standard routine esophagectomy vs active surveillance after neoadjuvant chemoradiation. Main Outcomes and Measures The primary outcome was quality-adjusted life-years (QALYs); the secondary outcome was life-years. Additional model scenarios explored (1) quality-of-life impacts of esophagectomy modeled as a time-varying covariate and (2) 2-year outcomes to align with the SANO trial time horizon. Sensitivity analyses evaluated recurrence probabilities and surgery-related quality-of-life trade-offs. Results At 5 years, standard surgery yielded greater QALYs (1.74 vs 1.34; incremental gain of 0.40 QALYs or ~4.8 months in perfect health) and life-years (3.11 vs 2.41; incremental gain of 0.70 life-years or ~8.4 months) compared with active surveillance. However, at a 2-year horizon, active surveillance was preferred for QALYs (incremental gain of ~15 days), consistent with the SANO trial. Sensitivity analyses revealed the model favored active surveillance when the recurrence probability was less than 43%, the likelihood of local/resectable recurrence was greater than 94%, or the negative quality-of-life impact of esophagectomy was substantial. Modeling esophagectomy’s quality-of-life impact as time limited further strengthened surgery’s long-term QALY benefit. Conclusions and Relevance This study found that while active surveillance offers short-term quality-of-life benefits and may be appropriate in select patients, particularly those at low recurrence risk or with high surgical risk, esophagectomy remains the preferred strategy for maximizing long-term survival and QALYs. These findings support a nuanced, individualized approach to post-nCRT management, balancing organ preservation with long-term oncologic outcomes.

ImportancePrior research has shown differences in postoperative outcomes for patients treated by female and male surgeons. It is important to understand, from a health system and payer perspective, whether surgical health care costs differ according to the surgeon’s sex.ObjectiveTo examine the association between surgeon sex and health care costs among patients undergoing surgery.Design, Setting, and ParticipantsThis population-based, retrospective cohort study included adult patients undergoing 1 of 25 common elective or emergent surgical procedures between January 1, 2007, and December 31, 2019, in Ontario, Canada. Analysis was performed from October 2022 to March 2023.ExposureSurgeon sex.Main Outcome and MeasureThe primary outcome was total health care costs assessed 1 year following surgery. Secondarily, total health care costs at 30 and 90 days, as well as specific cost categories, were assessed. Generalized estimating equations were used with procedure-level clustering to compare costs between patients undergoing equivalent surgeries performed by female and male surgeons, with further adjustment for patient-, surgeon-, anesthesiologist-, hospital-, and procedure-level covariates.ResultsAmong 1 165 711 included patients, 151 054 were treated by a female surgeon and 1 014 657 were treated by a male surgeon. Analyzed at the procedure-specific level and accounting for patient-, surgeon-, anesthesiologist-, and hospital-level covariates, 1-year total health care costs were higher for patients treated by male surgeons ($24 882; 95% CI, $20 780-$29 794) than female surgeons ($18 517; 95% CI, $16 080-$21 324) (adjusted absolute difference, $6365; 95% CI, $3491-9238; adjusted relative risk, 1.10; 95% CI, 1.05-1.14). Similar patterns were observed at 30 days (adjusted absolute difference, $3115; 95% CI, $1682-$4548) and 90 days (adjusted absolute difference, $4228; 95% CI, $2255-$6202).Conclusions and RelevanceThis analysis found lower 30-day, 90-day, and 1-year health care costs for patients treated by female surgeons compared with those treated by male surgeons. These data further underscore the importance of creating inclusive policies and environments supportive of women surgeons to improve recruitment and retention of a more diverse and representative workforce.

AbstractBackgroundPost‐operative pain management is a critical component of perioperative care. Patients at risk of poorly controlled post‐operative pain may benefit from early measures to optimize pain management. We sought to identify risk factors for post‐operative pain and opioid consumption in patients undergoing liver resection.MethodsThis is a multi‐institutional prospective nested cohort study of patients undergoing open liver resection. Opioid consumption and pain scores were collected following surgery. To estimate the effects of patient factors on opioid consumption (oral morphine equivalents—OME) and on pain scores (NRS‐11), we used generalized linear models and multivariable linear regression model, respectively.ResultsOne hundred and fifty‐three patients who underwent open liver resection between 2013 and 2016 were included in the study. The mean patient age was 62.2 years, and 43.3% were female. Younger patients were significantly more likely to use more opioids in the early post‐operative period (16.7 OME/10 years, p < 0.001). Patient factors that were significantly associated with increased NRS‐11 pain scores also included younger patient age (difference in pain score of 0.3/10 years with cough and 0.2/10 years at rest, p < 0.01 for both) as well as a history of analgesic use (difference in pain score of 0.9 with cough and 0.6 at rest, p < 0.01 and p = 0.07, respectively).ConclusionYounger patients and those with a history of analgesic use are more likely to report higher post‐operative pain and require higher doses of opioids. Early identification of these patients, and measures to better manage their pain, may contribute to optimal perioperative care.

AbstractBackgroundThe study aims were to model acute pain intensity and opioid consumption trajectories up to 72 hr after open hepatic resection, identify predictors of trajectory membership and examine the association between trajectory memberships and 6‐month pain and psychological outcomes. This is a long‐term analysis of a published randomized controlled trial on the impact of medial open transversus abdominis plane catheters on post‐operative outcomes.MethodsA total of 152 patients (89 males; mean age 63.0 [range: 54–72]) completed questionnaires on pain and related characteristics pre‐operatively and 6 months post‐operatively. Total opioid use was recorded several times over a 72‐hr period while self‐reported pain intensity scores were collected multiple times until hospital discharge. Analyses were carried out using growth mixture modelling, logistic regression and general linear models.ResultsBoth pain intensity and opioid consumption showed that a four‐trajectory model best fits the data. Patients in the lowest opioid consumption trajectory were more likely to be classified in the constant mild pain intensity trajectory. Age and baseline levels of anxiety significantly predicted opioid trajectory membership while baseline depressive symptoms significantly predicted pain intensity trajectory membership. Patients in the two highest opioid consumption trajectories reported significantly higher levels of pain catastrophizing at 6 months compared to patients in the other 3 trajectories (all p < 0.05).ConclusionHigh consumption of opioids after surgery is associated with higher levels of pain catastrophizing 6 months later. Identification of patients within these trajectories may lead to the development of early interventions targeted to high risk individuals.SignificanceDifferences in initial levels of opioid consumption and rates of change in opioid consumption shortly after surgery can help predict long‐term psychological responses to pain. Identifying key characteristics associated with initial opioid consumption can lead to the development of cost‐effective early interventions targeted to high risk individuals.

Objective: Conventional management of pain following open liver resection involves intravenous, patient-controlled analgesia (IV PCA) or epidural analgesia. The objective of this trial was to assess the efficacy of a regional technique called Medial Open Transversus Abdominis Plane (MOTAP) catheter analgesia compared with IV PCA. Methods: This was a blinded, randomized, controlled parallel-arm trial conducted at 2 high-volume centers. Patients undergoing liver resection through a subcostal incision were enrolled. Using a standardized technique, 2 catheters were placed after resection: one in the plane between internal oblique and transversus abdominis and the other in the posterior rectus sheath. Patients were randomized to receive ropivacaine 0.2% (ROP) or saline (NS) through both catheters for 72 hours. All patients received IV PCA with hydromorphone as part of a multimodality analgesia program. Primary outcome was opioid use over the first 48 hours. Results: One hundred fifty-three patients were included in the analysis (71 ROP, 82 NS). Patients receiving ROP used significantly less opioid than patients with NS at 48 hours (median 39.6 mg morphine-equivalent vs 49.2 mg, P = 0.033) and at 72 hours (median 50.0 vs 66.4 mg, P = 0.046). Pain scores at rest and with coughing were significantly lower at all time points in patients who received ROP (P = 0.002). Median length of hospital stay was 5 days in patients receiving ROP and 6 days in patients who received NS (P = 0.035). There was no difference between groups in complications [ROP 20 (28.2%) vs NS 26 (31.7%), P = 0.63]. Conclusion: MOTAP catheter analgesia reduces opioid requirements, pain, and length of hospital stay compared with IV PCA following open liver resection with subcostal incisions.
