Operative management of primary hyperparathyroidism in Europe.

BACKGROUND: Multicentre studies have previously reported on national outcomes of surgery for primary hyperparathyroidism, but not investigated whether management and outcome are uniform among countries. This study investigated whether there are differences among European countries in operative management and outcome of surgery for primary hyperparathyroidism. METHODS: Using data from Eurocrine®, a pan-European registry for endocrine surgeries, a retrospective observational cross-sectional multicentre study with 99 participating centres in 14 European countries was performed. Data on age, sex, calcium levels, operative strategy, conversion rate and rate of failed exploration were analysed for patients who underwent initial surgery for sporadic primary hyperparathyroidism. Primary outcome measures were intention to perform limited parathyroidectomy and the rate of hypercalcaemia at first follow-up. RESULTS: A total of 9548 patients were registered between 2015 and 2020. There were 7642 (80%, range 74.5-93.2%) females. There was intention to perform limited parathyroidectomy in 7320 of 9548 (76.7%) operations, ranging from 498 of 1007 (49.5%) to 40 of 41 (97.6%) among countries. Hypercalcaemia at first follow-up (median time to follow-up 15 days) was found in 416 of 9548 (4.4%) operations, ranging from 0 of 119 (0%) to 3 of 38 (7.9%) among countries. CONCLUSION: This study demonstrated large differences in the intention to perform limited parathyroidectomy for primary hyperparathyroidism among European countries, as well as differences in the rate of postoperative hypercalcaemia. Future studies are needed to evaluate the impact of these different healthcare practices on patient outcomes.

"Unresectable" polyp management utilizing advanced endoscopic techniques results in high rate of colon preservation.

PURPOSE: "Endoscopically unresectable" benign polyps identified during screening colonoscopy are often referred for segmental colectomy. Application of advanced endoscopic techniques can increase endoscopic polyp resection, sparing patients the morbidity of colectomy. This retrospective case-control study aimed to evaluate the success of colon preserving resection of "endoscopically unresectable" benign polyps using advanced endoscopic techniques including endoscopic mucosal resection, endoscopic submucosal dissection, endoluminal surgical intervention, full-thickness laparo-endoscopic excision, and combined endo-laparoscopic resection. METHODS: A prospectively maintained institutional database identified 95 patients referred for "endoscopically unresectable" benign polyps from 2015 to 2018. Cases were compared to 190 propensity score matched controls from the same database undergoing elective laparoscopic colectomy for other reasons. Primary outcome was rate of complete endoscopic polyp removal. Secondary outcomes included length of stay, unplanned 30-day readmission and reoperation, 30-day mortality, and post-procedural complications. RESULTS: Advanced endoscopic techniques achieved complete polyp removal without colectomy in 66 patients (70%). Failure was most commonly associated with previously attempted endoscopic resection and occult malignancy. Compared with matched colectomy controls, endoscopic polyp resection resulted in significantly shorter hospital length of stay (1.13 ± 2.41 vs 3.89 ± 4.57 days; p < 0.001), lower unplanned 30-day readmission (1.1% vs 7.7%; p < 0.05), and fewer postoperative complications (4.2% vs 33.9%; p < 0.001). Unplanned 30-day reoperation (2.1% vs 4.4%; p = 0.34) and 30-day mortality (0% vs 0.6%; p = 0.75) trended lower. CONCLUSIONS: Endoscopic resection of complex polyps can be highly successful, and it is associated with favorable outcomes and decreased morbidity when compared with segmental colon resection. Attempting colon preservation using these techniques is warranted.

Full-Thickness Laparoendoscopic Excision for Management of Complex Colon Polyps.

BACKGROUND: Benign colon polyps are increasingly being detected because of improved colonoscopic screening and early detection of masses on the adenoma-to-carcinoma pathway. Full-thickness laparoendoscopic excision is a colon-preserving technique for endoscopically unresectable polyps consisting of endoscopically guided nonanatomic wedge colectomy. OBJECTIVE: This study aimed to evaluate the safety and success of full-thickness laparoendoscopic excision compared to segmental colectomy for complex polyps not amenable to endoscopic resection. DESIGN: This is a retrospective case-control study. SETTINGS: This study was conducted at a tertiary academic center. PATIENTS: A prospectively maintained institutional database identified 22 patients with benign complex polyps managed with full-thickness laparoendoscopic excision from 2015 to 2020. These patients were compared with 22 propensity score-matched controls from the same database that underwent laparoscopic segmental colectomy. MAIN OUTCOME MEASURES: Primary outcome was inpatient length of stay. Secondary outcomes included operative details and postoperative morbidities. RESULTS: Full-thickness laparoendoscopic excision was successful in all patients. Patients had a median age of 64 years (41-85), and 82% were men. Final pathology revealed complete excision of benign lesions in 20 of 22 patients and adenocarcinoma in 2 of 22. For the adenocarcinomas, 1 patient underwent subsequent elective colectomy without complications, and 1 patient declined surgery. Propensity score matching was successful for age, sex, BMI, ASA score, colon location, and prior abdominal surgery. Compared with controls, cases had significantly shorter operative time (89.5 minutes (46-290) vs 122 minutes (85-200), p = 0.009), length of stay (1 day (0-17) vs 3 days (1-8), p < 0.001), and reduced blood loss (5 mL (2-15) vs 25 mL (10-150), p < 0.001). Thirty-day morbidity (9.1% vs 27.3%, p = 0.240) was not significantly different. An unplanned 30-day reoperation was performed in 1 patient for suspected small-bowel obstruction. There was 1 mortality due to decompensated cirrhosis in the treatment group. LIMITATIONS: This study was limited by its single-institution retrospective design. CONCLUSIONS: Full-thickness laparoendoscopic excision is safe and successful compared with corresponding segmental colectomy for complex polyps. Favorable postoperative outcomes, including decreased operative time, length of stay, and blood loss, make it a useful approach for managing complex polyps throughout the colon.

Reduction of Opioid Overprescribing and Use Following Standardized Educational Intervention: A Survey of Patient Experiences Following Anorectal Procedures.

BACKGROUND: A pilot study conducted at our institution showed that a significant amount of prescribed postoperative opioids is left unused with the potential for diversion and misuse. OBJECTIVE: This study aimed to evaluate the impact of provider- and patient-targeted educational interventions on postoperative opioid prescription and use following anorectal procedures. DESIGN: Patients were enrolled on July 2019 through March 2020 after implementing educational interventions (study) and were compared with the pilot study group (control) enrolled on August 2018 through May 2019. A telephone survey was conducted 1 week postoperatively. SETTINGS: This study was conducted at a 600-bed, safety-net hospital in southern California. PATIENTS: Adult patients undergoing ambulatory anorectal procedures were included. Patients who had undergone an examination under anesthesia, had been incarcerated, and had used opioids preoperatively were excluded. INTERVENTIONS: Educational interventions were developed based on the pilot study results. Providers received education on recommended opioid prescription quantities and a multimodal pain regimen. Standardized patient education infographics were distributed to patients pre- and postoperatively. MAIN OUTCOME MEASURES: The primary outcomes measured were total opioid prescribed, total opioid consumed, pain control satisfaction levels, and the need for additional opioid prescription. RESULTS: A total of 104 of 122 (85%) patients enrolled responded to the survey and were compared with the 112 patients included in the control group. Despite similar demographics, the study cohort was prescribed fewer milligram morphine equivalents (78.8 ± 11.3 vs 294.0 ± 33.1, p < 0.001), consumed fewer milligram morphine equivalents (23.0 ± 28.0 vs 57.1 ± 45.8, p < 0.001), and had a higher rate of nonopioid medication use (72% vs 10%, p < 0.001). The 2 groups had similar pain control satisfaction levels (4.1 ± 1.3 vs 3.9 ± 1.1 out of 5, p = 0.12) and an additional opioid prescription requirement (5% vs 4%, p = 1.0). LIMITATIONS: This study was limited by its single-center experience with specific patient population characteristics. CONCLUSION: Educational interventions emphasizing evidence-based recommended opioid prescription quantities and regimented multimodal pain regimens are effective in decreasing excessive opioid prescribing and use without compromising satisfactory pain control in patients undergoing ambulatory anorectal procedures.

REDUCCIN DE LA SOBREPRESCRIPCIN Y EL USO DE OPIOIDES DESPUS DE UNA INTERVENCIN EDUCATIVA ESTANDARIZADA UNA ENCUESTA DE LAS EXPERIENCIAS EN PACIENTES POSTOPERADOS DE PROCEDIMIENTOS ANORRECTALES: ANTECEDENTES:Un estudio piloto realizado en nuestra institución mostró que una cantidad significativa de opioides posoperatorios recetados no se usa, con potencial de desvío y uso indebido.OBJETIVO:Evaluar el impacto de las intervenciones educativas dirigidas al paciente y al proveedor sobre la prescripción y el uso de opioides posoperatorios después de procedimientos anorrectales.DISEÑO:Los pacientes se incluyeron entre julio de 2019 y marzo de 2020 después de implementar intervenciones educativas (estudio) y se compararon con el grupo de estudio piloto (control) inscrito entre agosto de 2018 y mayo de 2019. Se realizó una encuesta telefónica una semana después de la cirugía.ENTORNO CLÍNICO:Hospital de 600 camas en el sur de California.PACIENTES:Pacientes adultos sometidos a procedimientos anorrectales ambulatorios. Los criterios de exclusión fueron pacientes que recibieron un examen bajo anestesia, pacientes encarcelados y uso preoperatorio de opioides.INTERVENCIONES:Se desarrollaron intervenciones educativas basadas en los resultados del estudio piloto. Los proveedores recibieron educación sobre las cantidades recomendadas de opioides recetados y un régimen multimodal para el dolor. Se distribuyeron infografías estandarizadas de educación para el paciente antes y después de la operación.PRINCIPALES MEDIDAS DE RESULTADO:Opioide total prescrito, opioide total consumido, niveles de satisfacción del control del dolor y necesidad de prescripción adicional de opioides.RESULTADOS:Un total de 104 de 122 (85%) pacientes inscritos respondieron a la encuesta y se compararon con los 112 pacientes incluidos en el grupo de control. A pesar de una demografía similar, a la cohorte del estudio se le prescribió menos miligramos de equivalente de morfina (MME) (78,8 ± 11,3 frente a 294,0 ± 33,1, p <0,001), consumió menos MME (23,0 ± 28,0 frente a 57,1 ± 45,8, p <0,001) y presentaron una mayor tasa de uso de medicamentos no opioides (72% vs 10%, p <0,001). Los dos grupos tenían niveles similares de satisfacción del control del dolor (4,1 ± 1,3 frente a 3,9 ± 1,1 de 5, p = 0,12) y la necesidad de prescripción de opioides adicionales (5% frente a 4%, p = 1,0).LIMITACIONES:Experiencia en un solo centro con características específicas de la población de pacientes.CONCLUSIÓN:Las intervenciones educativas que enfatizan las cantidades recomendadas de prescripción de opioides basadas en la evidencia y los regímenes de dolor multimodales reglamentados son efectivas para disminuir la prescripción y el uso excesivos de opioides sin comprometer el control satisfactorio del dolor en pacientes sometidos a procedimientos anorrectales ambulatorios.

Outcomes of colostomy takedown following Hartmann's procedure: successful restoration of continuity comes with a high risk of morbidity.

AIM: Restoration of bowel continuity following a Hartmann's procedure is a major surgical undertaking associated with significant morbidity. The aim of this study was to review the authors' experience with Hartmann's reversal. METHOD: This was a retrospective review of consecutive patients from institutional databases who were selected to undergo open or laparoscopic Hartmann's reversal at two tertiary academic referral centres and a public safety net hospital (2010-2019). The main outcome measure was the rate of successful stoma reversal. Secondary outcomes included 30-day postoperative outcomes and procedural details. RESULTS: One hundred and fifty patients underwent attempted reversal during the study period, which was successful in all but three patients (98%). Patients were 59% Hispanic and 73% male, with a mean age of 48.7 ± 14.1 years, mean American Society of Anesthesiologists classification of 2.2 ± 0.6 and mean body mass index (BMI) of 28.6 ± 5.3 kg/m2 , with 39% of patients having a BMI > 30 kg/m2 . The mean time interval between the index procedure and reversal was 14.4 months, 53% of the index cases were performed at outside institutions and the most common index diagnoses were diverticulitis (54%), abdominal trauma (16%) and colorectal malignancy (15%). In 22% of cases a laparoscopic approach was used, with 42% of these requiring conversion to open. Proximal diverting stomas were created in 32 patients (21%), of which 94% were reversed. The overall morbidity rate was 54%, comprising ileus (32%), wound infection (15%) and anastomotic leak (6%), with a major morbidity rate (Clavien-Dindo ≥ 3) of 23%. CONCLUSION: Hartmann's reversal remains a highly morbid procedure. Our results suggest that operative candidates can be successfully reversed, but there is significant morbidity associated with restoration of intestinal continuity, particularly in obese patients. A laparoscopic approach may decrease morbidity in selected patients but such cases have a high conversion rate.

Aspiration Therapy As a Tool to Treat Obesity: 1- to 4-Year Results in a 201-Patient Multi-Center Post-Market European Registry Study.

PURPOSE: The objective of this post-market study was to evaluate long-term safety and efficacy of aspiration therapy (AT) in a clinical setting in five European clinics. MATERIALS AND METHODS: The AspireAssist® System (Aspire Bariatrics, Inc. King of Prussia, PA) is an endoscopic weight loss therapy utilizing a customized percutaneous endoscopic gastrostomy tube and an external device to aspirate approximately 30% of ingested calories after a meal, in conjunction with lifestyle counseling. A total of 201 participants, with body mass index (BMI) of 35.0-70.0 kg/m2, were enrolled in this study from June 2012 to December 2016. Mean baseline BMI was 43.6 ± 7.2 kg/m2. RESULTS: Mean percent total weight loss at 1, 2, 3, and 4 years, respectively, was 18.2% ± 9.4% (n/N = 155/173), 19.8% ± 11.3% (n/N = 82/114), 21.3% ± 9.6% (n/N = 24/43), and 19.2% ± 13.1% (n/N = 12/30), where n is the number of measured participants and N is the number of participants in the absence of withdrawals or lost to follow-up. Clinically significant reductions in glycated hemoglobin (HbA1C), triglycerides, and blood pressure were observed. For participants with diabetes, HbA1C decreased by 1% (P < 0.0001) from 7.8% at baseline to 6.8% at 1 year. The only serious complications were buried bumpers, experienced by seven participants and resolved by removal/replacement of the A-Tube, and a single case of peritonitis, resolved with a 2-day course of intravenous antibiotics. CONCLUSION: This study establishes that aspiration therapy is a safe, effective, and durable weight loss therapy in people with classes II and III obesity in a clinical setting. TRIAL REGISTRATION: ISRCTN 49958132.

Tertiary Care Multidisciplinary Teams Associated with Improved Survival in Rectal Cancer Patients: A Comparative Study.

For stage II/III rectal cancer patients, comprehensive multidisciplinary care (MDC) affects outcomes. Randomized trials have shown the effectiveness of adjuvant and neoadjuvant therapy in treatment of these patients. However, the effectiveness of collaboration within MDC is undetermined. It is possible that regional variation in survival outcomes may be tied to treatment facility. We retrospectively reviewed a prospectively collected database of patients with stage II/III rectal cancer who received MDC at any location and underwent oncologic colorectal resection at a tertiary care center (TCC) between 2005 and 2011. Of the 571 rectal cancer patients, 391 had a stage II/III rectal cancer and received surgery at a TCC. After exclusion criteria, we observed that 120 patients received neoadjuvant therapy and 119 patients received adjuvant therapy. For neoadjuvant patients, no difference in overall survival was observed between treatment received at a TCC versus an outside facility. However, a significant improvement in survival was observed in patients who received adjuvant therapy at a TCC (P = 0.01). Thus, the location of postoperative adjuvant therapy shows improvement in 10-year survival at a TCC versus elsewhere. Thus, standardization of care can impact outcomes for invasive rectal cancer patients. The limitations of this study are its retrospective nature and relatively small sample size.

Aspiration therapy for obesity; a safe and effective treatment.

BACKGROUND: This study evaluated the efficacy and safety of the novel AspireAssist® Aspiration Therapy System for treatment of obesity, and its effect on patient's quality of life. METHODS: A prospective observational study with 25 obese subjects, mean age 48 years (range 33-65), was performed. A custom gastrostomy tube (A-tube, Aspire Bariatrics) was percutaneously inserted during a gastroscopy performed under conscious sedation. Drainage and irrigation of the stomach were performed 3 times daily, 20 min after each meal, for 1-2 years. Efficient aspiration required thorough chewing of ingested food. Treatment included a cognitive behavioral weight loss program. RESULTS: Mean body mass index (BMI) at inclusion was 39.8 kg/m2 (range 35-49). After 1 year mean (SD) BMI was 32.1 kg/m2 (5.4), p < 0.01, and excess weight loss was 54.4% (28.8), p < 0.01. Quality of life, as measured with EQ-5D, improved from 0.73 (0.27) to 0.88 (0.13), p < 0.01. After 2 years BMI was 31.0 kg/m2 (5.1), p < 0.01, and excess weight loss was 61.5% (28.5), p < 0.01. There were no serious adverse events or electrolyte disorders. Compliance was 80% after 1 year and 60% after 2 years. CONCLUSIONS: Aspiration therapy is an efficient and safe treatment for obesity, and weight reduction improves quality of life. Excess weight was approximately halved in a year, with weight stability if treatment was continued. TRIAL REGISTRATION: Trial Register ISRCTN 49958132. Retrospectively registered 28/02/2014.

A novel endoscopic weight loss therapy using gastric aspiration: results after 6 months.

BACKGROUND AND STUDY AIMS: Obesity is a major public health problem with few effective treatment options. A novel device for treating obesity, the AspireAssist aspiration therapy system, was evaluated. PATIENTS AND METHODS: After 4 weeks taking a very-low-calorie diet, 25 obese men and women (BMI 39.8 ±â€Š0.9 kg/m(2)) had the AspireAssist gastrostomy tube placed during a gastroscopy. A low-profile valve was installed 14 days later and aspiration of gastric contents was performed approximately 20 minutes after meals three times per day. Cognitive behavioral therapy was also started. RESULTS: At month 6, mean weight lost was 16.5 ± 7.8 kg in the 22 subjects who completed 26 weeks of therapy (P = 0.001). The mean percentage excess weight lost was 40.8 ± 19.8 % (P = 0.001). Two subjects were hospitalized for complications: one subject for pain after gastrostomy tube placement, which was treated with analgesics, and another because of an aseptic intra-abdominal fluid collection 1 day after gastrostomy tube placement. No clinically significant changes in serum potassium or other electrolytes occurred. CONCLUSION: In this study, substantial weight loss was achieved with few complications using the AspireAssist system, suggesting its potential as an attractive therapeutic device for obese patients. Trial Register ISRCTN 49958132.

Very low calorie diet without aspartame in obese subjects: improved metabolic control after 4 weeks treatment.

BACKGROUND: Very low calorie diet (VLCD) is routinely used in programs for treatment of obesity and before bariatric surgery in order to reduce risk of postoperative complications. Aspartame, an artificial sweetener, is commonly used in VLCD and is well approved as a food additive without any adverse effects. The development of a new fructose containing VLCD formula without aspartame raises questions as to effects on glucose and lipid control. METHODS: As part of an ongoing study of a novel bariatric surgery procedure, twenty-five obese subjects with mean body mass index (BMI) 39.8 kg/m2 and mean age of 48.8 years enrolled in a single center observational study. Seven subjects presented with type 2 diabetes mellitus. The subjects underwent four weeks dietary treatment with VLCD Slanka (Slanka). Blood samples including fasting plasma glucose, HbA1c, cholesterol and triglycerides were performed at start and after four weeks of diet. Blood pressure and weight were noted. RESULTS: All subjects completed the diet without any adverse events. Mean weight reduction was 8.2 kg with 95% confidence interval 7.1-9.2 kg (p = 0.001). Excess weight (i.e. proportion of weight exceeding BMI 25) loss decreased by median 19.5% (inter quartile range (IQR) 16,8-24,2). Median fasting plasma glucose was at inclusion 5,6 mmol/l (IQR 5,3-6,8) and after diet 4.8 mmol/l (IQR 4,6-5,2) (p = 0.001). Median HbA1c changed from 39 mmol/mol (IQR 37-44) to 37 mmol/mol (IQR 35-43) (p = 0.001). There was also significant reduction in cholesterol and triglyceride levels as well as in systolic blood pressure. Changes in other monitored blood chemistry values were without clinical importance. CONCLUSION: Four weeks treatment with fructose containing VLCD of obese subjects preparing for bariatric surgery gave a substantial weight reduction without any significant negative metabolic effects.

Laparoscopic gastrostomy in children with congenital heart disease.

AIM: The aim of this study was to study the type and frequency of complications and change in weight after a laparoscopic gastrostomy procedure in 31 children with congenital heart disease, comparing patient groups of children with univentricular and biventricular circulation, and with completed and uncompleted cardiac surgery. METHODS: The method used was that of a retrospective study of all 31 children with congenital heart disease who underwent a laparoscopic gastrostomy at our center from 1995 to 2004. MAIN OUTCOME MEASURES: Postoperative complications and body weight changes during follow-up were the main outcome measures used in this study. RESULTS: Minor stoma-related problems were common in both groups. Two severe complications requiring an operative intervention occurred in the univentricular circulation group. Weight was normal at birth, low at the time of the gastrostomy procedure, and did not catch up completely during the follow-up period of a mean of 20 months. There were no significant differences regarding mean weight gain between the groups. CONCLUSIONS: The complication rate after the laparoscopic gastrostomy procedure was higher in our patient group, compared to previously studied children with various diseases. Comparisons regarding mean weight gain between the groups showed no significant differences. The mean weight gain was low, suggesting that the energy expenditure in this patient group of children with severe congenital heart disease may be even higher than previously assumed.
