Successful Design and Implementation of a POEM Program for Achalasia in an Integrated Healthcare System.

BACKGROUND: Per Oral Endoscopic Myotomy (POEM) is a minimally invasive treatment for achalasia with results comparable to laparoscopic Heller myotomy (LHM). Studies have described the development of proficiency for endoscopists learning to perform POEM, and societies have defined educational and technical objectives for advanced endoscopy fellows in training. However, there is limited guidance on the organizational strategy and educational plan necessary to develop an achalasia service with POEM expertise. AIMS: We aim to outline the steps for design and implementation of a successful POEM program. METHODS: We reported our experience developing a multi-disciplinary clinical program for POEM and the steps taken to achieve procedural proficiency. We also reported our technical success (successful tunneling into the gastric cardia and myotomy of LES muscle fibers) and clinical success (post-procedure Eckardt score ≤ 3) at 3-6 months and 12 months post-procedure. Adverse events were classified per the ASGE lexicon for endoscopic adverse events. RESULTS: After creating a multi-disciplinary clinical program for achalasia and completing procedural proficiency for POEM, our technical success rate was 100% and clinical success rate 90% for the first 41 patients. One adverse event (2.4%) occurred, moderate in severity per the American Society of Gastrointestinal Endoscopy (ASGE) lexicon for adverse endoscopic events. CONCLUSION: In this study, we outlined the steps involved to establish a POEM service in a large integrated healthcare system. Prior competency in interventional endoscopy, procedural training models, POEM observation and education, proctorship, and interdisciplinary patient care are recommended.

Patients Older 65 Years With Early Breast Cancer Prefer Intraoperative Radiation as a Locoregional Treatment Choice.

BACKGROUND: Patients 65 years old or older with early endocrine-responsive breast cancer have many treatment options, including no radiation. This study aimed to evaluate treatment preference when intraoperative radiation therapy (IORT) is offered in this population. METHODS: The study reviewed patients 65 years old or older with a diagnosis of early-stage endocrine-responsive breast cancer in 2016-2019 at a single hospital in a large integrated health care system. Electronic medical records of multidisciplinary breast tumor board discussion, treatment options documented by the treatment team, and final treatment offered were reviewed. Variables including age at biopsy, language, endocrine treatment, and comorbidities were collected. Regression analysis was used to evaluate for variables associated with patients' choice regarding radiation treatment. RESULTS: The institutional IORT guidelines were met by 63 patients in the described age group who had a documented offer of all radiation treatment options. The median age of the patients was 70 years (interquartile range 63-77 years). Overall, 74.6% of the patients chose IORT, and 14.3% opted for whole-breast irradiation. Only 4.8% chose to omit radiation after breast-conserving surgery, and 6.3% chose mastectomy. The patients who chose IORT were more likely to receive endocrine treatment (odds ratio 3.70; p = 0.03). Age, race, language, and comorbidities were not associated with preference for IORT (p < 0.05). CONCLUSIONS: Patients 65 years old or older with early-stage endocrine-responsive breast cancer preferred to have IORT despite counsel about the lack of survival benefit. This study suggests that local cancer control with the convenient radiation delivery method is important to the described patient population.

Volume Matters: Longitudinal Retrospective Cohort Study of Outcomes Following Consultation and Standardization of Adrenal Surgery.

PURPOSE: Subspecialization of adrenal surgery through regionalization has not been adequately evaluated. We assessed implementation of subspecialization and the association of regionalization with adrenalectomy outcomes in a community-based setting. METHODS: In this longitudinal retrospective cohort study, we used an interrupted time series analysis on consecutive adrenal surgeries at Kaiser Permanente Northern California, 2010-2019. The intervention was regionalization of surgery in 2016. Main outcomes include surgical volumes, operative time, length of stay, 30-day return-to-care, and 30-day complications obtained from the electronic medical record. t-Tests and multivariable models were used to analyze time trends in outcomes after accounting for changes in patient and disease characteristics. RESULTS: In total, 850 adrenal surgery cases were eligible. Between 2010 and 2019, the annual incidence of surgery (per 100,000 persons) increased from 2.4 (95% CI 1.9-3.1) to 4.1 (95% CI 3.5-4.8). Average annual surgeon volume increased from 2.4 (95% CI 1.6-3.1) to 9.9 (95% CI 4.9-14.9), while hospital volume increased from 3.5 (95% CI 2.3-4.6) to 15.4 (95% CI 6.9-24.0). Operative time was 34 (23-45) min faster in 2018-2019 compared with 2010-2011. After regionalization, same-day discharges increased to 64% in 2019 (p < 0.0001). The frequency of return-to-care (p = 0.69) and the overall complication rate (p = 0.31) did not change. CONCLUSIONS: Regionalizing adrenal surgery through surgical subspecialization and standardized care pathways was feasible and decreased operative time, and hospital stay, while increasing the frequency of same-day discharges without increasing return-to-care or complications.

Intraoperative Radiation Therapy: A Large Integrated Health Care System's Approach and Outcomes.

Introduction Intraoperative radiation therapy (IORT) may not be as effective in the community compared with clinical trials. Methods The authors reviewed data from the electronic health records of patients who received IORT between February 2014 and February 2020 at a single center within a large integrated health care system. The primary outcome was ipsilateral breast tumor recurrence. Results Of 5731 potentially eligible patients, 245 (4.3%) underwent IORT (mean age: 65.4 ± 0.4 years; median follow-up time: 3.5 years ± 2.2 months). According to the American Society for Radiation Oncology's accelerated partial breast irradiation guidelines based on final pathology, 51% of patients were suitable candidates for IORT, 38.4% were cautionary, and 10.6% were unsuitable. For adjuvant therapy, 6.5% had consolidative whole breast irradiation, and 66.4% received endocrine treatment. At the median follow-up time of 3.5 years, overall ipsilateral breast tumor recurrence was 3.7%. Recurrences tended to be more frequent in patients who refused or did not complete endocrine treatment than in those who received it (7.4% vs 1.9%, p = 0.07). The complication rate was 14.7%, with seroma being the most common (8.2%). Discussion The IORT ipsilateral breast tumor recurrence rate of 3.7% confirms a higher-than-expected rate compared to randomized clinical trials, possibly due to less compliance with endocrine therapy. Conclusion The authors subsequently revised their IORT protocol to require endocrine treatment as a part of the IORT treatment plan and to strongly recommend adjuvant whole breast irradiation for all patients deemed cautionary or unsuitable for IORT according to the American Society for Radiation Oncology's accelerated partial breast irradiation guidelines.

Rapid evolution of a Morgagni hernia with herniation of the left hepatic lobe: case report and review of the literature.

Morgagni hernias are a rare form of congenital diaphragmatic hernia, commonly found on cross-sectional imaging. Repair is generally performed electively for pulmonary or gastrointestinal symptoms. Our case presented acutely with gastric obstruction. Two months prior she had a small bowel obstruction and underwent computed tomography, diagnostic laparoscopy, lysis of adhesions and takedown of the falciform ligament, where a 'groove' to the left of the falciform was noted, but not repaired. We collected the presentation, technique, complications and results of 12 prior cases. A trans-abdominal, robotic-assisted tissue repair of the diaphragm with mesh reinforcement utilizing as few as three ports appears to be safe and effective. The robotic platform offers additional degrees of freedom, making retrosternal operating more ergonomic to the surgeon. The rapid progression of our patient suggests that repair at the time of discovery should be considered so that the serious complications can be avoided.

Same-Day Home Recovery for Benign Foregut Surgery.

Importance: Same-day home recovery (SHR) is now the standard of care for many major surgical procedures and has the potential to become standard practice for benign foregut procedures (eg, hiatal hernia repair, fundoplication, and Heller myotomy). Objective: To determine whether SHR for patients undergoing benign foregut surgery is feasible, safe, and effective. Design, Setting, and Participants: This prospective cohort study took place across 19 medical centers within an integrated health care system in northern California from January 2019 through September 2021. Participants included consecutive patients undergoing elective benign foregut surgery. Exposures: Standardized SHR program. Main Outcomes and Measures: The primary end point was the rate of SHR. The secondary end points were 7-day and 30-day rates of postoperative emergency department visits, hospital readmissions, and reoperations. Results: Of 1248 patients who underwent benign foregut surgery from January 2017 through September 2021, 558 were patients before implementation of the SHR program and 690 were patients postimplementation. The mean age of patients was 60 years, and 759 (59%) were female. The preimplementation SHR rate was 64 of 558 patients (11.5%) in 2018 and increased to 82 of 113 patients (72.6%) by 2021 (94/350 [26.9%] in 2019 and 112/227 [49.3%] in 2020; P < .001). There were no statistical differences in the 7-day and 30-day rates of postoperative emergency visits, hospital readmissions, and reoperations or 30-day mortality in the SHR vs non-SHR groups in the postimplementation era. Conclusions and Relevance: In this study, implementation of a regional SHR program among patients undergoing elective benign foregut surgery was feasible, safe, and effective. The changes in perioperative care require comprehensive patient education and full multidisciplinary support. An SHR program for benign foregut procedures has the potential to improve patient care and cost-effectiveness in care delivery.

Video. Hand-assisted laparoscopy for wandering spleen.

A wandering spleen is a rare condition with an unknown incidence. The lack of short gastric vessels and suspensory ligaments is thought to result from a fusion anomaly of the dorsal mesogastrium of the spleen. The major risk in performing a splenectomy for patients with a wandering spleen is overwhelming postsplenectomy infection (OPSI). The incidence of OPSI is 0.13% to 8.1%, with a mortality rate of 30% to 60%. Laparoscopic splenopexy provides the benefits of minimally invasive surgery while avoiding the complications of splenectomy. The reported case presents a patient with a wandering spleen. The patient, an 18-year-old woman, experienced a malarial infection at the age of 5 years and had a computed tomography (CT) scan documenting her spleen in the normal anatomic position. When she was 18 years old, a CT scan showed her spleen located in the right lower quadrant (RLQ). At laparoscopy, the presence of the spleen in the RLQ was confirmed. The spleen could not be easily manipulated with laparoscopic instruments, so a hand port was used to mobilize the spleen to the left upper quadrant (LUQ). No evidence of attenuated suspensory ligaments was seen. The spleen was secured in the left subdiaphragmatic location by the use of a Vicryl mesh bag. An omental sling was used to support the spleen further. A 1-year follow up CT confirmed that the spleen still was located in the correct anatomic position. This is a unique case in that the patient was known to have a normally located spleen at a young age and then found to have a wandering spleen later in life. This could have resulted from a congenital fusion anomaly or attenuation of the patient's suspensory ligaments caused by her previous malarial infection and splenomegaly.

Experience with a Nonopioid Protocol in Ambulatory Breast Surgery: Opioids are Rarely Necessary and Use is Surgeon-Dependent.

CONTEXT: Surgeons write 1.8% of all prescriptions and 9.8% of all opioid prescriptions. Even small doses prescribed for short-term use can lead to abuse; thus, surgeons are uniquely able to combat the opioid epidemic by changing prescribing practices. As part of a department wide quality improvement project, we initiated a nonopioid protocol for all patients undergoing ambulatory breast surgery. OBJECTIVE: To determine the feasibility of a nonopioid protocol for patients undergoing ambulatory breast surgery and to determine if patient-related factors contribute to surgeon adherence to a nonopioid protocol in ambulatory breast surgery. DESIGN: Retrospective chart review of a prospectively collected database, with χ2 analysis and a multiple logistic regression model with the surgeon as the random effect. MAIN OUTCOME MEASURE: Protocol adherence. RESULTS: A total of 180 patients, with a median age of 63 years (range = 18-95 years), were included. Of these, 127 (70.6%) did not receive opioids; in this group there were 2 hematomas (1.6%), and 3 patients required an opioid prescription (2.4%). Fifty-three (29.4%) were prescribed opioids against protocol; in this group, there was 1 hematoma (1.9%). The operating surgeon was the only variable independently correlated with protocol adherence (p < 0.0001). Age, race/ethnicity, surgery type, and history of long-term opioid use were not. CONCLUSION: Ambulatory breast surgery patients tolerated a nonopioid pain regimen well. Surgeons' decisions, rather than patient characteristics, primarily drove the choice of pain management in our study. We believe our protocol can be improved with stricter implementation and education, which must be balanced with practitioner independence.

Two-Stage Explantation of a Magnetic Lower Esophageal Sphincter Augmentation Device Due to Esophageal Erosion.

INTRODUCTION: Implanting a magnetic lower esophageal sphincter augmentation device (LINX, Torax Medical) has become an increasingly common option in the surgical management of gastroesophageal reflux disease. As the enthusiasm for placing this device increases, experience in the management of device-related complications-including erosion-is necessary. METHODS: We report a staged approach to LINX removal in a 64-year-old female with symptoms of odynophagia secondary to partial erosion of a LINX device into the esophagus. RESULTS: The patient had a 12-bead LINX device placed in 2011 at an outside, international facility. In late 2013, she began experiencing symptoms of odynophagia. An esophagogastroduodenoscopy at our institution in October 2015 demonstrated two metallic beads eroding through the distal esophageal lumen. An elective endoscopic removal of the two visible beads was performed. A postoperative esophagram confirmed that there was no resulting esophageal perforation. The patient noted mild improvement in her symptoms. After a 12-week period to allow for complete healing, the remaining 10 beads of the LINX device were explanted laparoscopically without complication. No further procedures were undertaken. At 2 months' follow-up, the patient noted complete resolution of her symptoms. CONCLUSION: Transmural erosion of the LINX device into the esophageal lumen is a rare occurrence, with only five such complications reported in the published literature. We present the first account of LINX explantation for esophageal erosion in the United States. We demonstrated that a staged laparoendoscopic approach to LINX removal in these cases is feasible with minimal morbidity.

Predictors of prolonged hospital stay following open and laparoscopic gastric bypass for morbid obesity: body mass index, length of surgery, sleep apnea, asthma, and the metabolic syndrome.

BACKGROUND: The number of weight reduction operations performed for type II and type III obesity is rapidly escalating. Risk of surgery has been infrequently stratified for patient subgroups. The purpose of this study was to identify patient characteristics that increased the odds of a prolonged hospital length of stay (LOS) following open or laparoscopic Roux-en-Y gastric bypass (RYGBP). METHODS: The hospital records of 311 patients who underwent RYGBP in a 6-month period were retrospectively reviewed. Patient characteristics including the presence of significant obesity-related medical conditions were recorded. Analysis was based on intent to treat. Univariate and step-wise logistic regression analysis was used to identify the odds ratio (OR) and adjusted odds ratio (AOR) for predictors of an increased hospital LOS. RESULTS: Datasets for 311 patients were complete.159 patients underwent open vertical banded gastro-plasty-Roux-en-Y gastric bypass (VBG-RYGBP) and152 laparoscopic RYGBP (LRYGBP). 78% of patients were female. Median age was 40 years (range 18-68). Median BMI was 49 kg/m2 (range 35-82). 17% of patients had sleep apnea, 18% asthma, 19% type 2 diabetes, 13% hypercholesterolemia and 44% hypertension. Median length of surgery for open VBG-RYGBP (64 minutes) was significantly faster than forLRYGBP (105 minutes). Median length of stay was significantly shorter for LRYGBP (2 days) than openVBG-RYGBP (3 days). Univariate logistic regression analysis identified 6 predictors of increased LOS:open surgery (0.4 OR); increasing BMI (60 kg/m2 0.38 OR; BMI 70 kg/m2 0.53 OR); increasing length of surgery (120 min 0.33 OR; 180 min 0.48 OR); sleep apnea (2.25 OR); asthma (3.73 OR); and hypercholesterolemia (3.73 OR). Subset analysis identified patients with the greatest odds for a prolonged hospital stay: women with asthma (2.47 AOR) or coronary artery disease (8.65 AOR); men with sleep apnea (5.54 OR) or the metabolic syndrome (6.67-10.20 OR); and patients undergoing a laparoscopic operation with sleep apnea (11.53 AOR) or coronary artery disease(12.15 AOR). CONCLUSIONS: Open surgery, BMI, length of surgery,sleep apnea, asthma and hypercholesterolemia all increased the odds of a prolonged LOS. Patients with the greatest odds of long LOS were women with asthma or coronary disease, men with sleep apnea or the metabolic syndrome, and patients undergoing laparoscopic surgery with sleep apnea or coronary artery disease. Patients at high-risk for prolonged hospital stay can be identified before undergoingRYGBP. Surgeons may wish to avoid high-risk patients early in their bariatric surgery experience.

Myelolipoma in the spleen: a rare discovery of extra-adrenal hematopoietic tissue.

Myelolipomas are benign tumors usually found within the adrenal gland. Approximately 50 cases of extra-adrenal myelolipomas have been reported in the literature and all are associated with additional lesions. Myelolipomas contain hematopoetic cells and adipose tissue. Most commonly, they are asymptomatic and are found incidentally on radiologic imaging. Here we report a case of an isolated intrasplenic myelolipoma as an incidental finding during the work up for myasthenia gravis in an otherwise asymptomatic man. The spleen and associated mass were excised during laparotomy and the patient had an uneventful recovery.
