Study Design: Retrospective analysis of New York State Inpatient Database years 2004-2013., Objective: Assess rates of spinal diagnoses and procedures before and after bariatric surgery (BS)., Summary of Background Data: BS for morbid obesity helps address common comorbidity burdens and improves quality of life for patients. The effects of BS on spinal disorders and surgical intervention have yet to be investigated., Materials and Methods: Patients included in analysis if they underwent BS and were seen at the hospital before and after this intervention. Spinal conditions and rates of surgery assessed before and after BS using χ 2 tests for categorical variables. Multivariable logistic regression analysis used to compare rates in BS patients to control group of nonoperative morbidly obese patients. Logistic testing controlled for comorbidities, age, biological sex., Results: A total of 73,046 BS patients included (age 67.88±17.66 y, 56.1% female). For regression analysis, 299,504 nonbariatric, morbidly obese patients included (age 53.45±16.52 y, 65.6% female). Overall, rates of spinal symptoms decreased following BS (7.40%-5.14%, P <0.001). Cervical, thoracic, lumbar spine diagnoses rates dropped from 3.28% to 2.99%, 2.91% to 2.57%, and 5.39% to 3.92% (all P <0.001), respectively. Most marked reductions seen in cervical spontaneous compression fractures, cervical disc herniation, thoracic radicular pain, spontaneous lumbar compression fractures, lumbar spinal stenosis, lumbar spondylosis. Controlling for comorbidities, age and sex, obese nonbariatric patients more likely to have encounters associated with several cervical, thoracic or lumbar spinal diagnoses and procedures, especially for cervical spontaneous compression fracture, radicular pain, lumbar spondylosis, lumbar spinal stenosis, posterior procedures. BS significantly lowered comorbidity burden for many specific factors., Conclusions: BS lowered rates of documented spinal disorders and procedures in a morbidly obese population. These findings provide evidence of additional health benefits following BS, including reduction in health care encounters for spinal disorders and rates of surgical intervention., Competing Interests: The authors declare no conflict of interest., (Copyright © 2022 Wolters Kluwer Health, Inc.

Bouveret syndrome, a rare cause of intestinal obstruction, occurs by passage of a gallstone through a cholecystoduodenal fistula into the intestinal lumen. Presenting symptoms are nausea, vomiting, and abdominal pain. In some cases, chronic symptoms result in weight loss. Typically, the syndrome is diagnosed via x-ray, ultrasound, or computed tomography. Treatment options are endoscopic or surgical. Endoscopic approaches include mechanical lithotripsy, electrohydraulic lithotripsy, stone extraction, laser lithotripsy, extracorporeal shockwave lithotripsy, and/or duodenal stenting. When stone fragments migrate distally, surgical removal becomes necessary. We describe a distinct endoscopic treatment via stone breakage, followed by pushing the fragments of the stone into the jejunum, resolving the intestinal obstruction., (© 2019 The Author(s).

Background: Bariatric surgery (BS) is an increasingly common treatment for morbid obesity that has the potential to effect bone and mineral metabolism. The effect of prior BS on spine surgery outcomes has not been well established. The aim of this study was to assess differences in complication rates following spinal surgery for patients with and without a history of BS., Methods: Retrospective analysis of the prospectively collected New York State Inpatient Database (NYSID) years 2004-2013. BS patients and morbidly obese patients (non-BS) were divided into cervical and thoracolumbar surgical groups and propensity score matched for age, gender, and invasiveness and complications compared., Results: One thousand nine hundred thirty-nine spine surgery patients with a history of BS were compared to 1625 non-BS spine surgery patients. The average time from bariatric surgery to spine surgery is 2.95 years. After propensity score matching, 740 BS patients were compared to 740 non-BS patients undergoing thoracolumbar surgery, with similar comorbidity rates. The overall complication rate for BS thoracolumbar patients was lower than non-BS (45.8% vs 58.1%, P < 0.001), with lower rates of device-related (6.1% vs 23.2%, P < 0.001), DVT (1.2% vs 2.7%, P = 0.039), and hematomas (1.5% vs 4.5%, P < 0.001). Neurologic complications were similar between BS patients and non-BS patients (2.3% vs 2.7%, P = 0.62). For patients undergoing cervical spine surgery, BS patients experienced lower rates of bowel issues, device-related, and overall complication than non-BS patients (P < 0.05)., Conclusions: Bariatric surgery patients undergoing spine surgery experience lower overall complication rates than morbidly obese patients. This study warrants further investigation into these populations to mitigate risks associated with spine surgery for bariatric patients.

A 48 year-old African American woman presented to her physician complaining of a rapidly evolving epigastric and right upper quadrant abdominal pain. A PET-CT of the abdomen and pelvis demonstrated hypermetabolic, polypoid masses within the gallbladder and several tumors in the left lobe of the liver for which she underwent diagnostic laparoscopy. The gallbladder revealed a 3.5 × 3.3 × 2.4 tan-brown exophytic mass located at the fundus and growing into the lumen with multiple contiguous papillary projections arising from the mucosal surface. A concurrent large cell neuroendocrine carcinoma and papillary adenocarcinoma of the gallbladder was revealed histologically. There was shared reactivity to antibodies directed against the distinct antigens for each morphological component with transitional tumor cells (of both histological components) located at the areas where the two tumor types merged, revealing common immunoreactivity for carcinoembryonic antigen, cancer antigen 19-9, keratin 19, c-kit (cluster of differentiation protein 117 (CD117)) and epithelial cell adhesion molecule. Ultrastructurally, individual cells were demonstrated to have overlapping features of neuroendocrine and glandular differentiation. The aforementioned histological, ultrastructural and immunohistochemical profile is strongly suggestive of a biphenotypic stem/progenitor cell tumor of the gallbladder., (© 2011 The Authors.

Unlabelled:  Abstract: Negative pressure wound therapy (NPWT) has consistently shown significant clinical benefits in wound healing, but the mechanisms are not fully elucidated. While a reduction in bacterial burden is one possible contributor, studies have shown mixed results in this regard. The present study used a porcine infected wound model to test the effect of NPWT on bacterial burden., Methods: Infected wounds (Pseudomonas aeruginosa, coagulase negative Staphylococcus, and Bacteroides fragilis) in a porcine model were treated with V.A.C.® therapy with the standard GranuFoam™ dressing, V.A.C. therapy with the GranuFoam Silver® dressing, or moist gauze for a period of 7 days with three dressing changes. Quantitative and semiquantitative bacterial cultures, histological samples, and digital photographs were taken at dressing changes., Results: The wounds continued to show gross and microscopic improvement when treated with standard NPWT and NPWT with silver compared to moist wound care controls. However, the bacterial burden in all wounds continued to increase and broadened to include local skin flora, which had been absent immediately after wounding. These increases in bacteria were not affected by the use of silver dressings., Conclusion: Negative pressure wound therapy with either standard NPWT foam or silver NPWT foam produced significant improvements in local wound appearance. This occurred despite a persistently high level of bacterial infection; thus, the improvement in healing of these infected wounds cannot be explained by a change in the bacterial burden. .

Objective: To describe our experience with a single-incision laparoscopic cholecystectomy (SILC) performed using a flexible endoscope as the means of visualization and surgical dissection. The use of flexible endoscopy in intra-abdominal surgery has never been described., Design: Prospective observational case series., Patients: Eleven patients with symptomatic cholelithiasis were selected based on age, clinical presentation, body habitus, and history of previous abdominal surgery. Patients with acute or chronic cholecystitis were excluded., Results: All procedures were completed laparoscopically via the single umbilical incision without the need to convert to an open operation and without introduction of any additional laparoscopic instruments or trocars. The mean operative time was 149.5 minutes (range, 99-240 minutes). The mean length of hospital stay was 0.36 days. There were no associated intraoperative or postoperative complications., Conclusions: In our experience, SILC performed with a flexible endoscope is feasible and safe. Further studies are needed to determine its advantages in reference to postoperative pain and complication rate in juxtaposition with the current standard laparoscopic cholecystectomy.

Background: Abnormal positioning and size of the mitral valve contribute to the systolic anterior motion and mitral-septal contact that are important components of obstructive hypertrophic cardiomyopathy (HCM). The RPR repair (resection of the septum, plication of the anterior leaflet, and release of papillary muscle attachments) addresses all aspects of this complex pathology. This study reports outcomes regarding effectiveness of the RPR repair., Methods: Fifty consecutive unselected patients (average age, 55.8 years) undergoing RPR repair for obstructive HCM from 1997 to 2007 were studied. Each patient underwent preoperative and postoperative transthoracic echocardiograms to document gradient, ejection fraction, degree of mitral regurgitation, and systolic anterior motion. Intraoperative transesophageal echocardiogram was used to guide all surgical repairs. Clinical follow-up included patient interviews to determine New York Heart Association (NYHA) status., Results: Concomitant operations were performed in 25 patients (50%). Postoperative mortality was 0%. Average mean left ventricular outflow tract gradients decreased from 134 +/- 40 to 2.8 +/- 8.0. Mitral regurgitation improved from a mean of 2.5 to 0.1 (p < 0.001). Average length of stay was 6.9 +/- 2.7 days. NYHA class improved from 3.0 +/- 0.6 to 1.2 +/- 0.5. Follow-up was 100%, with a mean of 2.5 +/- 1.8 years. Average mitral regurgitation at follow-up was 0.9, with no residual systolic anterior motion., Conclusions: The RPR repair is safe and effective for symptomatic obstructive HCM. Our data support repair of the mitral valve that results in good intermediate outcomes with respect to gradient, mitral regurgitation, and clinical status.
