Distinction of papillary and adamantinomatous craniopharyngioma: Clinical features, surgical nuances and hypothalamic outcomes

ObjectiveUnderstanding the differences of suprasellar papillary and adamantinomatous craniopharyngiomas (PCPs/ACPs) is pivotal for target therapy, surgical strategy or postoperative management. Here, the clinical features, surgical nuances and postoperative hypothalamic outcomes of PCPs were systematically recapitulated. Methods24 PCPs and 52 ACPs underwent initial surgery were retrospectively reviewed. Clinical data, quantified third ventricle (3rd V) occupation and optic chiasm distortion were compared, as well as intra-operative findings, operating notes and prognosis. Moreover, analysis of tumor/3rd V relationship and hypothalamic outcomes were also performed. ResultsTumors were more likely to occupies the 3rd V cavity in PCPs. Chiasm distortion of “compressed forward” was the most common pattern (45.8 %) in PCPs, whereas “stretched forward” pattern accounted the highest (42.5 %) in ACPs. Besides, round-shaped with less calcification, duct-like recess, solid consistency, rare subdiaphragmatic invasion, visible lower stalk and improved postoperative visual outcome were more frequently observed in PCPs. The basal membranes of the tumor epithelium and the reactive gliosis were separated by a layer of collagen fibers in most PCPs, which differs from ACPs in the morphological examination of tumor/3rd V floor interface. In daytime sleepiness and memory difficulty, the PCPs showed significantly better outcomes than the ACPs groups, and PCPs suffered less postoperative weight gain (p < 0.05) than ACPs among adult-onset cases. ConclusionPCPs are different from ACPs regards the clinical features, operative techniques and outcomes. If necessary, PCPs are suggested more amenable to total removal since its less invasiveness to the 3rd V floor and better hypothalamic outcomes.

A Longitudinal analysis of weight changes before and after total hip arthroplasty: Weight trends, patterns, and predictors.

It is crucial to understand weight trends in patients undergoing total hip arthroplasty (THA). To evaluate preoperative and postoperative weight trends for patients undergoing primary THA and factors associated with clinically significant weight change. A prospective cohort who underwent primary unilateral THA (n= 3,011) at a tertiary healthcare system (January 2016 to December 2019) were included in the study. The primary outcomes were clinically significant weight change (> 5% change in body mass index [BMI]) during the one-year preoperative and one-year postoperative periods. Preoperatively, 66.6% maintained a stable weight, 16.0% gained and 17.4% lost weight, respectively. Postoperatively, 64.0% maintained a stable weight, while 22.6% gained and 13.4% lost weight, respectively. Female sex, Black race, obesity, higher Charlson Comorbidity Index (CCI) scores, and older age were associated with preoperative weight loss. Female sex, obesity, higher CCI scores, and Medicare insurance were associated with postoperative weight loss. Preoperative weight loss was associated with postoperative weight gain (OR = 3.37 [CI: 2.67 to 4.25]; p< 0.001), and preoperative weight gain was associated with postoperative weight loss (OR = 1.74 [CI: 1.30 to 2.3]; p< 0.001). Most patients maintained a stable BMI one-year before and one-year after THA. Several factors are associated with weight loss before and after THA. Preoperative weight changes were associated with a reciprocal rebound in BMI post-operatively.

The relationship of decision regret with quality of life and comfort level in patients undergoing laparoscopic sleeve gastrectomy: a cross-sectional study

BackgroundLaparoscopic sleeve gastrectomy (SG) is one of the effective methods of weight loss. It is essential to determine patients' regret and predictive factors to improve their quality of life and comfort. No study has investigated decision regret and affecting factors in patients undergoing SG in Turkey. ObjectivesThe study aimed to determine the relationship of decision regret with quality of life and comfort level in patients undergoing SG. SettingThe research was carried out with patients who had undergone SG in a private hospital in the west of Turkey. MethodsThe research was conducted as a descriptive, correlational, and cross-sectional study. Data were collected between March and May 2023, and the study was completed with 286 patients. Data were collected using the Personal Information Form, Decision Regret Scale (DRS), Quality of Life Following Obesity Surgery Scale (QoL-OS), and Comfort Scale. ResultsPatients’ mean score on the DRS was 5.27 ± 13.41 (0-100), the total mean score on the QoL-OS-Biopsychosocial dimension was 79.57 ± 9.35 (18-90), the mean score on the QoL-OS-Complications dimension was 17.17 ± 4.60 (7-35), and the environmental comfort score average was 8.87 ± 2.23 (0-10). Patients’ decision regret was significantly affected by the QoL-OS-Biopsychosocial Area dimension in the first place (Beta = −.516; P < .001), social comfort in the second place (Beta = −.278; P < .001), postoperative weight gain in the third place (Beta = .221; P < .001), and complication development in the fourth place (Beta = .163; P < .001). ConclusionsThe study revealed that patients’ decision regret levels were very low up to 3 years after surgery and found that low postoperative quality of life and social comfort level, postoperative weight gain, and complications affected decision regret.

Comparative Study of Laparoscopic Sleeve Gastrectomy With or Without Jejunal Bypass.

We evaluated the weight loss effect of laparoscopic sleeve gastrectomy (LSG) and jejunal bypass (JJB) in treating obesity by analyzing and comparing the effects of LSG with or without JJB. A retrospective analysis was performed on the data of 150 patients with obesity who underwent bariatric metabolic surgery in Affiliated Xiaolan Hospital,Southern Medical University from October 2014 to April 2019. The patients were divided into two groups, LSG and LSG + JJB, according to the different surgical methods. The differences in the percentage of excess weight loss (%EWL) and total weight loss (TWL) between the two groups were statistically analyzed. The %EWL of the patients in the LSG group reached the maximum value at one year and six months post-surgery and steadily decreased after two years post-surgery. In contrast, the %EWL of the patients in the LSG + JJB group gradually increased after two years post-surgery; however, no significant difference between the two groups was observed. The TWL in the LSG + JJB group was significantly greater than that in the LSG group at each follow-up point. Postoperative %EWL was similar in both groups. The TWL in the LSG + JJB group was greater than that in the LSG group, and the postoperative recurrent weight gain rate in the LSG + JJB group was lower than that in the LSG group.

Perioperative Delta Weight and Pediatric Obstructive Sleep Apnea Resolution after Adenotonsillectomy.

The first-line treatment for pediatric obstructive sleep apnea (OSA) is adenotonsillectomy. Post-operative weight gain is a well-documented phenomenon. We hypothesized that higher peri-adenotonsillectomy delta weight correlates with lower rates of OSA resolution in pediatric patients. This was a retrospective cohort study consisting of 250 patients from 2 to 17 years of age at a tertiary academic medical center between January 2021 and December 2022. Polysomnography results and body mass index (BMI) changes were collected through the electronic health record. Univariate and multivariate logistical regression analyses were performed, adjusting for confounding factors. Perioperative delta weight and pre-operative baseline AHI values were significant predictors of residual OSA. For every 1-kilogram gain in weight, the odds of residual OSA (AHI >5) increase by 6.0% (OR = 1.06, 95% CI = 1.02-1.10, p < 0.002), and the odds of residual severe OSA (AHI > 10) increase by 8% (OR = 1.08, 95% CI = 1.04-1.12, p < 0.001). Increased AHI, Black/African American race, and male sex were also factors associated with incomplete OSA resolution. Increased peri-adenotonsillectomy delta weight is associated with higher rates of residual OSA in children. Patients and families should be counseled about appropriate weight loss and control methods before adenotonsillectomy. IV Laryngoscope, 134:4141-4147, 2024.

Protocol to evaluate the efficacy and safety of tolvaptan in patients with refractory ascites after liver resection: an open-label, single-arm phase I/II study.

In patients with chronic liver diseases such as cirrhosis, massive ascites after hepatic resection is the cause of prolonged hospitalization and worsening prognosis. Recently, the efficacy of tolvaptan in refractory ascites has been reported; however, there are no reports on the efficacy or safety of tolvaptan for refractory ascites after hepatic resection. This study aims to evaluate the efficacy of early administration of tolvaptan in patients with refractory ascites after hepatic resection. This is an open-label, single-arm phase I/II study. This study subject will comprise patients scheduled for hepatic resection of a liver tumor. Patients with refractory ascites after hepatic resection (drainage volume on postoperative day 1 ≥5ml/body weight 1kg/day) will be treated with tolvaptan. The primary endpoint will include the maximum change in body weight after hepatic resection relative to the preoperative baseline. The secondary endpoints will include drainage volume, abdominal circumference, urine output, postoperative complication rate (heart failure and respiratory failure), number of days required for postoperative weight gain because of ascites to decrease to preoperative weight, change in improvement of postoperative pleural effusion, total amount of albumin or fresh frozen plasma transfusion, type and amount of diuretics used, and postoperative hospitalization days. This trial will evaluate the efficacy and safety of tolvaptan prophylaxis for refractory ascites after hepatic resection. As there are no reports demonstrating the efficacy of tolvaptan prophylaxis for refractory ascites after hepatic resection, the authors expect that these findings will lead to future phase III trials and provide valuable indications for the selection of treatments for refractory postoperative ascites.

Altered central pain processing in patients with degenerative lumbar diseases and its association with low physical activity levels after lumbar spinal surgeries: a retrospective cohort analysis.

To investigate the occurrence of altered central pain modulation in patients with degenerative lumbar diseases (DLDs) and to analyze its association with physical activity (PA) 3years after lumbar decompression and fusion. Preoperative assessments of pressure pain thresholds (PPTs), temporal summation (TS), conditioned pain modulation (CPM) and pain were, respectively, recorded in 304 patients. These patients further underwent International Physical Activity Questionnaire (IPAQ) and both pain-related and psychological assessments 3years post-operation. Preoperatively, the patients had lower PPTs in both local pain and pain-free areas and lower CPM and higher TS in pain-free areas than healthy subjects (P < 0.05). Postoperatively, 53.9% (164/304) patients showed PA below healthy-related thresholds (< 600 MET min/w). Low PA group showed a greater postoperative weight gain and bone loss and a higher postoperative prevalence of both moderate anxiety and marginal depression than high PA group (P < 0.05). All covariates with differences between the high and low PA groups were subjected to multivariate logistic regression, and long preoperative disease duration, low preoperative PPT in pain-free area, high preoperative TS, revision surgery, severe postoperative low back pain and significant postoperative pain catastrophizing thought were independently associated with low postoperative PA (P < 0.05). This study supports the existence of central sensitization (CS) caused by abnormal central pain modulation in DLDs. Pre-existing CS in these patients may be associated with low PA after lumbar surgeries, and this low-activity lifestyle may predispose patients to multiple adverse health outcomes. Preoperative dynamic quantitative sensory testing may provide information for the identification of at-risk patients.

A Longitudinal Analysis of Weight Changes before and after Total Knee Arthroplasty: Weight Trends, Patterns, and Predictors.

Longitudinal data on patient trends in body mass index (BMI) and the proportion that gains or loses significant weight before and after total knee arthroplasty (TKA) are scarce. This study aimed to observe patients longitudinally for a 2-year period and determine (1) clinically significant BMI changes during the 1 year before and 1 year after TKA and (2) identify factors associated with clinically significant weight changes.A prospective cohort of 5,388 patients who underwent primary TKA at a tertiary health care institution between January 2016 and December 2019 was analyzed. The outcome of interests was clinically significant weight changes, defined as a ≥5% change in BMI, during the 1-year preoperative and postoperative periods, respectively. Patient-specific variables and demographics were assessed as potential predictors of weight change using multinomial logistic regression.Overall, 47% had a stable weight throughout the study period (preoperative: 17% gained, 15% lost weight; postoperative: 19% gained, 16% lost weight). Patients who were older (odds ratio [OR] = 0.95), men (OR = 0.47), overweight (OR = 0.36), and Obese Class III (OR = 0.06) were less likely to gain weight preoperatively. Preoperative weight loss was associated with postoperative weight gain 1 year after TKA (OR = 3.03). Preoperative weight gain was associated with postoperative weight loss 1 year after TKA (OR = 3.16).Most patients maintained a stable weight before and after TKA. Weight changes during the 1 year before TKA were strongly associated with reciprocal rebounds in BMI postoperatively, emphasizing the importance of ongoing weight management during TKA and the recognition of patients at higher risk for weight gain.Level of evidence II (prospective cohort study).

Safety of limb lengthening after Roux-en-Y gastric bypass: an analysis of the MBSAQIP database

BackgroundRoux-en-Y gastric bypass (RYGB) effectively treats severe obesity, but some patients may require revisional surgery like limb lengthening (LL) for postoperative weight gain. ObjectivesThis study aims to compare 30-day serious complications and mortality rates between LL and primary RYGB, given limited safety data on LL. MethodsPatients who underwent LL and RYGB were identified from the 2020 and 2021 MBSAQIP databases, the only years in which LL data were available. Baseline characteristics and 30-day rates of serious complications and mortality were analyzed. ResultsA total of 86,990 patients underwent RYGB and 455 underwent LL. Patients undergoing RYGB were younger (44.4 versus 49.8 yr, P < .001), had a higher body mass index (BMI) (45.5 versus 41.8 kg/m2, P < .001) and higher rates of comorbidities including diabetes (30.0 versus 13.6%, P < .001). RYGB and LL had similar operative duration (125.3 versus 123.2 min, P = .5). There were no statistical differences between cohorts for length of stay (LOS) (1.6 RYGB versus 1.6 LL d, P = .6). After LL, there were higher 30-day rates of reoperation (3.3 versus 1.9%, P = .03) and deep surgical site infections (1.3 versus .5%, P = .03) compared to RYGB. There were no differences in overall serious complications (5.1 LL versus 5.0% RYGB, P = 1.0) and mortality (.2 LL versus .1% RYGB, P = .5). Multivariable logistic regression adjustment found that previous venous thromboembolism was associated with serious complications after LL. ConclusionsWhen compared to primary RYGB, LL has a favorable safety profile with similar 30-day rates of serious complications and mortality.

SHORT AND LONG-TERM RESULTS OF LAPAROSCOPIC ESOPHAGOCARDIOMYOTOMY WITH FUNDOPLICATION (HELLER-PINOTTI SURGERY) IN THE TREATMENT OF NON-ADVANCED ACHALASIA (MEGAESOPHAGUS).

Videolaparoscopic esophagocardiomyotomy with fundoplication has been a widely used technique for the treatment of achalasia. This study analyzes the safety and effectiveness of the technique in the treatment of non-advanced achalasia (megaesophagus) in a Brazilian federal university public hospital. To evaluate the short- and long-term results of videolaparoscopic treatment of non-advanced megaesophagus in a public university hospital in Brazil, employing the esophagocardiomyotomy technique with fundoplication. The medical records of 44 patients who underwent surgical treatment for non-advanced achalasia at the Clinical Hospital of Federal University of Uberlândia (UFU-MG), Minas Gerais, from January 2001 to July 2021 were analyzed. The following data were evaluated: gender, age, etiology, radiological classification of Rezende-Alves and Ferreira-Santos, immediate and late complications (mean follow-up of 31.4 months), need or not for conversion to open access, postoperative reflux, performance or not of endoscopic esophageal dilation in the preoperative period, postoperative mortality, frequency of pre and postoperative symptoms (persistent dysphagia, regurgitation, heartburn, vomiting, odynophagia, and weight loss), surgery time, hospital stay, duration of dysphagia, pre and postoperative weight, and Eckardt score. Among the analyzed patients, 23 (52.3%) were male, and 21 (47.7%) were female, with a mean age of 50.8 years. No early complications were recorded and there were 27.2% cases of late gastroesophageal reflux. Postoperative weight gain was 81.8% and the success rate of surgery according to the Eckardt score was 84.1%. Esophagocardiomyotomy with fundoplication is an effective and safe technique for the treatment of non-advanced achalasia.

Challenges in the care and treatment of patients with extreme obesity.

Obesity is a prevalent chronic disease. The management of extreme obesity - i.e., body mass index (BMI) ≥ 50 kg/m2 or obesity class IV and V - is still far from ideal. Individuals with extreme obesity have a high risk of surgical complications, mortality, comorbidities, and reduced weight loss following bariatric surgery. Although lifestyle changes and anti-obesity medications are recommended for all patients with extreme obesity as adjuvants to weight loss, these measures are less effective than bariatric surgery. As a first step, sleeve gastrectomy or an inpatient very-low-calorie diet should be incentivized to enhance weight loss before definitive surgery. Although malabsorptive procedures lead to greater weight loss, they are associated with an increased risk of early complications and malnutrition. Nonstandard techniques employed in clinical trial protocols, such as transit bipartition, may be performed as they maintain a weight loss potency comparable to that of the classic duodenal switch but with fewer nutritional problems. Anatomical causes should be investigated in patients with postoperative suboptimal clinical response or recurrent weight gain. In these cases, the initiation of anti-obesity drugs, endoscopic therapies, or a conversion procedure might be recommended. More studies are needed to address the specific population of patients with extreme obesity, as their outcomes are expected to be distinct from those of patients with lower BMI.

Risk of fluid accumulation after cardiac surgery

ObjectivePatients undergoing heart surgery are at high risk of postoperative fluid accumulation due to long procedures and cardiopulmonary bypass. In the present study, we sought to investigate the prevalence of postoperative fluid accumulation and its relation to adverse events in patients undergoing cardiac surgery. MethodsCAREBANK is prospective, single-center cohort study focusing on the adverse events after cardiac surgery. The study population was divided into 2 groups based on 5% postoperative weight gain. All the in-hospital adverse events are registered on the database. The end points of the present study were length of hospital stay, length of intensive care unit stay, occurrence of new-onset atrial fibrillation after hospital major bleeding episodes major cardiac events, cerebrovascular events, and death. Three-month and 1-year follow-up data also include all major adverse events. ResultsAltogether 1001 adult cardiac surgery patients were enrolled. The most frequent operations were coronary artery bypass grafting (56.3%). Five hundred fifty-four out of 939 (59.0%) patients had ≥5% weight gain during index hospitalization. Patients with a weight gain ≥5% were more likely to be women, have lower body mass index, had heart failure, and more often had preoperative atrial fibrillation. In-hospital period fluid accumulation was associated with reoperation due bleeding and longer total hospital stay. At 3 months' follow-up, weight gain 5% or more was associated with increased occurrence of new-onset atrial fibrillation, this was not reflected in the occurrence of strokes, transient ischemic attacks, or myocardial infarctions. ConclusionsPostoperative fluid excess is associated with adverse outcomes in cardiac surgery. Women, low-weight patients, and patients with cardiac failure or atrial fibrillation are prone to perioperative fluid accumulation.

Efficacy and safety of endoscopic retrograde cholangiopancreatography in recurrent pancreatitis of pediatric asparaginase-associated pancreatitis.

Asparaginase (ASP) is an important drug in combined chemotherapy regimens for pediatric acute lymphoblastic leukemia (ALL); ASP-associated pancreatitis (AAP) is the main adverse reaction of ASP. Recurrent pancreatitis is a complication of AAP, for which medication is ineffective. To evaluate the efficacy and safety of endoscopic retrograde cholangiopancreatography (ERCP) in treating recurrent pancreatitis due to AAP. From May 2018 to August 2021, ten children (five males and five females; age range: 4-13 years) with AAP were treated using ERCP due to recurrent pancreatitis. Clinical data of the ten children were collected, including their sex, age, weight, ALL risk grading, clinical symptoms at the onset of pancreatitis, time from the first pancreatitis onset to ERCP, ERCP operation status, and postoperative complications. The symptomatic relief, weight change, and number of pancreatitis onsets before and after ERCP were compared. The preoperative symptoms were abdominal pain, vomiting, inability to eat, weight loss of 2-7 kg, and 2-9 pancreatitis onsets. After the operation, nine of ten patients did not develop pancreatitis, had no abdominal pain, could eat normally; the remaining patient developed three pancreatitis onsets due to the continuous administration of ASP, but eating was not affected. The postoperative weight gain was 1.5-8 kg. There was one case of post ERCP pancreatitis and two cases of postoperative infections; all recovered after medication. ERCP improved clinical symptoms and reduced the incidence of pancreatitis, and was shown to be a safe and effective method for improving the management of recurrent pancreatitis due to AAP.

Increase in Postoperative Body Mass Index in Patients After Total Knee Arthroplasty.

Objectives The aim of this is to investigate the changes in body mass index (BMI) following knee arthroplasty and to evaluate their impact on patient-reported outcomes and functional evaluations. Methods This observational study included 90 patients who underwent total knee arthroplasty (TKA) and were followed up for a median period of 2.6 years. BMI measurements were recorded before and after surgery, and patient-reported outcomes and functional evaluations were assessed using standardized scales and tests. Results Following TKA, BMI increased statistically significantly (Wilcoxon signed-rank test, p < 0.000). In addition, half of the patients experienced an increase in BMI, with 32% moving up in their BMI category. However, there were no clinically significant differences in patient-reported outcomes or functional evaluations between the group that gained BMI and the group that maintained or lost BMI. Conclusion This study reveals that patients tend to have increased BMI following TKA. However, these BMI changes do not significantly impact patient-reported outcomes or functional evaluations. It underscores the importance of patient education regarding healthy lifestyle habits, including diet and physical activity, to address postoperative weight gain effectively.

Outcomes of open revascularization for chronic mesenteric ischemia at a tertiary care center in India.

Chronic mesenteric ischemia (CMI) is a rare, debilitating disease associated with higher morbidity and mortality if not treated on time. In the past two decades, there has been a paradigm shift in its management with endovascular modality due to reduced perioperative morbidity and mortality. In the endovascular era, only a few patients require surgical therapy. We conducted this study to report our experience with open surgical revascularization at our hospital. We have conducted a retrospective study after obtaining approval from Institutional Ethics Committee. Data regarding patients who underwent open revascularization for CMI with long-segment occlusion from 2016 to 2021 has been retrieved from the institutional database. The demographic data, clinical presentation, type of surgery and graft used, perioperative mortality and morbidity and length of hospital stay were evaluated. Overall survival and disease-free survival were assessed using Kaplan-Meier analysis. Twenty-one patients underwent open surgical revascularization; 16 were males and five females. The median age was 43years. Fourteen (66.7%) were smokers. The mean duration of follow-up was 28.4 ± 13.6months. Thirty-day postoperative mortality was 0% and morbidity was 28%. The average duration of hospital stay and postoperative weight gain were 6.9 ± 3.7days and 11 ± 4.9 kgs, respectively. One patient died at two years of follow-up due to myocardial infarction and one had a recurrence. Long-term survival at 60months of follow-up was 91.6% and the primary-patency rate was 95.2%. Owing to better long-term and reintervention-free patency, open revascularization should be considered in patients who are fit for surgery, particularly in patients with long-segment mesenteric artery occlusion.

Factors Influencing Patient Satisfaction With Breast Augmentation: A BREAST-Q Effect of Magnitude Analysis.

Breast augmentation is one of the most performed cosmetic surgeries. Despite this, patient satisfaction following breast augmentation is poorly understood. The aim of this study was to investigate what patient and surgical factors influence patient satisfaction following primary breast augmentation. The BREAST-Q Augmentation module was sent to all females undergoing primary breast augmentation at a single private clinic (Amalieklinikken, Copenhagen, Denmark) between 2012 and 2019. Patient and surgical characteristics at the time of surgery were obtained from the patients' medical records, and data on factors that occurred after the surgery (eg, breastfeeding) were obtained by patient contact. Multivariate linear regression modeled the impact of these factors on BREAST-Q outcomes. A total of 554 females with a mean follow-up time of 5 years after primary breast augmentation were included in this study. Implant type and volume did not affect patient satisfaction. However, higher patient age was associated with significantly higher postoperative patient satisfaction, psychosocial well-being, and sexual well-being (P < .05). Conversely, higher patient BMI, postoperative weight gain, and breastfeeding were associated with significantly lower satisfaction (P < .05). Additionally, subglandular implant placement was associated with significantly lower satisfaction than submuscular implant placement (P < .05). Implant type and volume did not affect patient satisfaction with breast augmentation. However, young age, higher BMI, subglandular implant placement, and postoperative weight gain were associated with lower patient satisfaction. These factors should be considered when aligning outcome expectations with breast augmentation.

Facial Hypertrophy as a Complication of Weight Gain in Autologous Fat Graft Patients: Considerations and Recommendations.

Fat grafting can be used to restore facial volume for reconstructive and cosmetic indications. Common practice often involves extracting lipoaspirate from the most abundant anatomic location. However, grafted fat retains the phenotypic characteristics of its original location and can undergo exaggerated hypertrophy with patient weight fluctuations. This study aims to systematically assess the literature to summarize the reported effects of postoperative weight gain on facial hypertrophy in patients after facial fat grafting and to determine potentially avoidable factors. A search through PubMed/MEDLINE (National Institutes of Health; Bethesda, MD) was conducted on October 4, 2022 to identify relevant articles using appropriate search terms. No lower date limit was used and all eligible non-animal clinical articles in English were included for review. Reports were summarized and presented as descriptive statistics. The search generated 714 articles. After abstract and full text review of the initial set of articles, six were included in our analysis. All articles described poor cosmetic outcomes resulting from non-anatomic hypertrophy of the grafted fat. None of the articles reported a thorough methodology for selecting the donor site to minimize fat hypertrophy with potential future weight fluctuations. Grafted facial fat is susceptible to exaggerated hypertrophy with changes in patient weight. Specifically, harvesting lipoaspirate from maximally abundant areas of the body may increase this risk. Individualizing the area of fat donation may attenuate unwanted fat growth and further contribute to increased quality of life over time.

Postoperative Weight Gain within Enhanced Recovery after Cardiac Surgery

Optimal fluid therapy during perioperative care as part of enhanced recovery after cardiac surgery (ERACS) should improve the outcome. Our objective was finding out the effects of fluid overload on outcome and mortality within a well-established ERACS program. All consecutive patients undergoing cardiac surgery between January 2020 and December 2021 were enrolled. According to ROC curve analysis, a cut-off of ≥7 kg (group M, n = 1198) and &lt;7 kg (group L, n = 1015) was defined. A moderate correlation was shown between weight gain and fluid balance r = 0.4, and a simple linear regression was significant p &lt; 0.0001, R2 = 0.16. Propensity score matching showed that increased weight gain was associated with a longer hospital length of stay (LOS) (L 8 [3] d vs. M 9 [6] d, p &lt; 0.0001), an increased number of patients who received pRBCs (L 311 (36%) vs. M 429 (50%), p &lt; 0.0001), and a higher incidence of postoperative acute kidney injury (AKI) (L 84 (9.8%) vs. M 165 (19.2%), p &lt; 0.0001). Weight gain can easily represent fluid overload. Fluid overload after cardiac surgery is common and is associated with prolonged hospital LOS and increases the incidence of AKI.

Factors Predicting Over-Time Weight Increase After Liver Transplantation: A Retrospective Study

Post-transplantation weight control is important for long-term outcomes; however, few reports have examined postoperative weight change. This study aimed to identify perioperative factors contributing to post-transplantation weight change. Twenty-nine patients who underwent liver transplantation between 2015 and 2019 with an overall survival of >3 years were analyzed. The median age, model for end-stage liver disease score, and preoperative body mass index (BMI) of the recipients were 57, 25, and 23.7, respectively. Although all but one recipient lost weight, the percentage of recipients who gained weight increased to 55% (1 month), 72% (6 months), and 83% (12 months). Among perioperative factors, recipient age ≤50 years and BMI ≤25 were identified as risk factors for weight gain within 12 months (P < .05), and patients with age ≤50 years or BMI ≤25 recipients gained weight more rapidly (P < .05). The recovery time of serum albumin level ≥4.0 mg/dL was not statistically different between the 2 groups. The weight change during the first 3 years after discharge was represented by an approximately straight line, with 18 and 11 recipients showing a positive and negative slope, respectively. Body mass index ≤23 was identified as a risk factor for a positive slope of weight gain (P <.05). Although postoperative weight gain implies recovery after transplantation, recipients with a lower preoperative BMI should strictly manage body weight as they may be at higher risk of rapid weight increase.
