Health-Related Quality of Life effects of rectus repair during body contouring surgery in post-bariatric patients: A prospective study.

BACKGROUND: Massive weight loss after bariatric surgery often leads to psychological and physical dissatisfaction, resulting in an increased demand for body contouring surgery (BCS). As a result of these surgeries, Health-Related Quality of Life (HRQL) is improved. However, little is known about the impact of rectus plication during BCS on HRQL. METHODS: This multicenter prospective cohort study included post-bariatric primary BCS patients with a minimum follow-up period of 12 months between January 2016 and December 2019. Patients were divided into two groups based on plication status. Using the BODY-Q, a patient-reported outcome measure, HRQL was measured preoperatively and at least 12 months postoperatively. Six HRQL domains were investigated: Body image, physical function, psychological function, sexual function, social function, and physical symptoms. RESULTS: A total of 305 patients were included in this study: 201 of these patients (66%) did not undergo plication, while 104 patients (34%) did. HRQL improved significantly 12 months after BCS in all measured domains, regardless of plication status. Delta scores were significantly higher in the plication group in all HRQL domains. After adjusting for baseline score and other significant variables through multivariate linear regression, three scales remained significant: Body image (P = 0.001), psychological function (P = 0.035), and sexual function (P = 0.035). CONCLUSIONS: Three out of six domains showed significant improvement in HRQL after BCS with rectus plication, predominantly body image. Preoperative counseling and surgical planning could benefit from this information. The long-term effects of rectus plication on HRQL should be explored in future research.

Consequences and predisposing factors of self-discharge against medical advice in plastic and hand surgery.

PURPOSE: Therapeutic success of surgical interventions is significantly affected by patients' adherence. Patient autonomy can lead to unreasonable behavior. We analyzed the consequences and predisposing factors of patient self-discharge in a plastic and hand surgery cohort. STUDY DESIGN AND SETTING: Data was collected retrospectively in a case-control study with n = 73 patients who had self-discharged in a 10-year time period and n = 130 controls (discharge by the surgeon). Data was collected through the hospital information systems and a particular questionnaire. Statistical analyses were performed via chi-squared test and logistic regression analyses. RESULTS: Patients who self-discharged against medical advice had a significantly higher complication rate (p = 0.045) and a higher number of revision operations (p < 0.001). They were more often dissatisfied with the primary inpatient treatment (p < 0.05). Secondly, they lived more often in shared households (p = 0.002; OR 5.387 (1.734-16.732)) or had to take care of their children at home (p = 0.006; OR 1.481 (1.280-1.741)). There was a significantly lower pain score (NAS) on time of self-discharge (p = 0.002) as well as 24 h after self-discharge (p < 0.001) in self-discharged patients. CONCLUSION: Self-discharge was associated with predisposing factors and poorer outcomes. Patient autonomy can lead to health-compromising behavior and patients should be counseled accordingly.

Expected Reduction of The Nipple-Areolar Complex Over Time After Treatment of Gynecomastia with Ultrasound-Assisted Liposuction Mastectomy Compared to Subcutaneous Mastectomy Alone.

BACKGROUND: The enlarged nipple-areola-complex (NAC) is a characterizing aspect of gynecomastia. OBJECTIVE: The purpose of this study was to multidimensionally quantify the reduction of the NAC after a subcutaneous mastectomy (SCM) with or without ultrasound-assisted liposuction (UAL). MATERIALS AND METHODS: A retrospective assessment of patients who underwent SCM +/- UAL due to gynecomastia over a period of 11 years was conducted. The NAC diameters were measured before and after surgery. In addition, a survey (including the BREAST-Q) regarding patient-oriented outcome was performed. RESULTS: The study cohort consisted of 55 men and resulting 105 NACs (SCM n=63, SCM+UAL n=42). It could be shown that the reduction of the NAC considering all parameters (horizontal and vertical diameter and the area) was significantly larger (p=<0.001) in the SCM+UAL compared to the SCM only cohort. The mean reduction of the area in the SCM cohort was 1.60cm2 (SD 1.48) or 23.37% (SD 9.78) after 5.82 years and in the SCM+UAL cohort 2.60cm2 (SD 1.60) or 35.85% (SD 6,86) after 7.43 years. As independent significant factors for reduction of the NAC, the resection weight and SCM+UAL combination were identified. There were no significant differences regarding the patients' satisfaction measured with the BODY-Q (p=0.222) and the ordinal scale (p=0.445) between the two cohorts. CONCLUSIONS: The SCM with UAL showed a larger reduction over time of the NAC compared to the SCM independent from the stage of gynecomastia. When planning the surgical treatment of gynecomastia, a technique and resection weight dependent reduction of the NAC over time must be considered.

Prospective randomized controlled trial on comparison of standard CO2 pressure pneumoperitoneum insufflator versus AirSeal®.

BACKGROUND: AirSeal® is a valve-free insufflation system that enables a stable pneumoperitoneum with continuous smoke evacuation and CO2 recirculation during laparoscopic surgery. Comparative evidence on the use of AirSeal® and standard CO2 insufflator in laparoscopic general surgery procedures is scarce. The aim of this study was to compare surgical outcomes between AirSeal® and standard CO2 insufflators in patients undergoing the most frequently performed laparoscopic procedures. METHODS: One hundred and ninety-eight patients undergoing elective laparoscopic cholecystectomy, colorectal surgery and hernia repair were randomized to either AirSeal® (group A) or standard pressure CO2 insufflator (group S). The primary endpoints were operative time and level of postoperative shoulder tip pain (Visual Analog Scale). Secondary outcomes included Clavien-Dindo grade complications, surgical side effect and length of hospital stay. RESULTS: Patients were randomized to either group A (n = 101) or group S (n = 97) and were analyzed by intention-to-treat. There was no significant difference in mean operative time between the groups (median [IQR]; 71 min [56-94] in group A vs. 69 min [52-93] in group S; p = 0.434). Shoulder tip pain levels were significantly lower in group S (VAS 0 [0-3] in group S vs. 2 [0-4] in group A; p = 0.001). There was no significant difference in complications, surgical side effects (subcutaneous emphysema was not observed in any group) and length of hospital stay. CONCLUSION: This randomized controlled trial showed that using the AirSeal® system did not reduce operative time and was associated with a higher postoperative shoulder tip pain compared to standard CO2 insufflator for short elective surgeries.

Risk Factors for Complications after Skin-Sparing and Nipple-Sparing Mastectomy.

INTRODUCTION: In order to achieve a complication-free breast reconstruction, it is fundamental for each individual patient case to determine preoperatively certain risk factors that might have a negative impact on the postoperative result after skin-sparing (SSM) or nipple-sparing mastectomy (NSM). METHODS: A retrospective study of 39 female breast cancer patients who received SSM or NSM breast reconstruction in our department (time interval: 2010-2015), was performed. The study focus is on determining patient characteristics (e.g., demographics, history of radiotherapy/chemotherapy, menopausal status, amount of resected breast tissue) leading to higher complication rates. RESULTS: Overall, 50 mastectomies (27 SSM and 23 NSM) with 6 immediate and 35 immediate 2-stage tissue expander breast reconstructions amounting to a total of 41 surgical interventions (n = 41) were carried out. Median follow-up time was 2 years and 5 months (range 121-1,863 days). Increased complication rates were associated with the following patient characteristics: age >50 years (p < 0.05) and personal history of cardiovascular disease (p < 0.05). Increased but not significant risk factors included postmenopausal status (p = 0.07), radiotherapy prior to SSM/NSM (p = 0.06), and weight of resected breast tissue >438 g (p = 0.09). CONCLUSION: This work identified age >50 years and personal history of cardiovascular disease to be risk factors for increased complication rates following SSM and NSM. Therefore, the given findings should be taken into account when selecting patients for these 2 procedures.

How to become a medical professor - a comparative analysis of academic requirements in Germany and the United States.

BACKGROUND: The acquisition of a medical professorship represents a significant step in a physician's academic career. The responsibility as well as the honor and the associated obligations are significant; however, the requirements to become a medical professor vary in Germany. OBJECTIVE: We analyzed the variable requirements for prospective medical professors in Germany, with special focus on the tenure track concept and the U.S. system. METHODS: Based on an online research, we queried German medical faculty regulations to obtain a medical professorship within Germany. RESULTS: We analyzed 35 German universities. On average, 11 publications are required after "venia legendi" to meet professorship (apl) prerequisites (median x̅ = 10, max = 24, min = 6, n = 16), whereas 6 publications with first or last authorship are required on average (x̅ = 6, max = 16, min = 4, n = 26). In most German universities, it takes an average of 4 years after gaining habilitation to apply for a professorship (x̅ = 5 years, max = 6 years, min = 2 years). Candidates for university chair positions, however, can shorten this period by an average of 38%. DISCUSSION: In the German academic system, the prerequisites to gain a professorship differ among universities. Due to different scientific cooperation and exchange programs, research and academic activities have reached an intense international exchange level. Yet there is no international or even national standardization, quality assurance, and comparability to gain a medical professorship.

[Impact of delayed presentation of patients with hand infections to hand surgeons: a retrospective single-centre study of 379 patients]. / Auswirkung der verspäteten Vorstellung von Handinfektionen beim Handchirurgen ­ eine retrospektive Single-Center-Studie von 379 Patienten.

OBJECTIVE: This study investigates the impact of the presentation time of patients with hand infections to hand surgeons on hospital stay and the frequency of necessary operations. PATIENTS AND METHODS: 379 patients with hand infections treated in our clinic from 2007 to 2014 were evaluated retrospectively for time of presentation to hand surgeon, time of trauma, length of stay, and frequency of necessary operations. RESULTS: On average, a surgical presentation delayed by more than one day extended the hospital stay by 1.22 days (KHVD) (95 % CI: 1.20-1.25, p < 0.001). Also, the odds of having to undergo surgery increased by 13.59 % each day (95 % CI 4.01 % -25.43 %, p < 0.001). KHVD also increased by a factor of 1.09 (95 % CI: 1.03-1.15, p < 0.001) with delayed antibiotic challenge. However, the time antibiotics were administered did not correlate with the need to undergo surgery (yes/no) (p = 0.11). CONCLUSION: Late presentation of patients with hand infections leads to a longer inpatient stay and a higher number of necessary operations. Early presentation of hand infections to an experienced hand surgeon is important to avoid complicated patient pathways that add costs to the healthcare system.

[German linguistic validation of the BODY-Q: standardised PRO instrument after bariatric and bodycontouring surgery]. / Deutschsprachige Validierung des Body-Q ­ standardisiertes PRO-Messinstrument nach bariatrischen und körperformenden Eingriffen.

One of the most important parts of result evaluation in plastic surgery, especially postbariatric and body-contouring surgery, is the appraisal of changes in patients' quality of life after treatment. Standardised assessments of patient-reported outcomes (PROs) are indispensable.BODY-Q (A. Klassen et al.) is a multifaceted, valid PRO instrument comprising a total of 26 scales for the evaluation of multiple factors of everyday life in order to quantify well-being, satisfaction and functionality. Each scale contains 4-10 statements, which have to be rated by patients.The BODY-Q was created pursuant to ISPOR (International Society for Pharmacoeconomics and Outcomes Research) standards and subjected to psychometric tests with great results. It is considered a standard PRO instrument for quality of life in postbariatric and body-contouring surgery.In order to expand the applicability of standardised questionnaires, ISPOR established linguistic validation guidelines, which have been applied to the BODY-Q in Dutch, Danish, Finnish and Polish.In this study, German linguistic validation was completed applying the standardised guidelines. First the BODY-Q was translated in consensus with medical expertise. Then a certified translator produced a backwards translation, which was commented on by the author. After appropriate changes were made in due consideration of these comments, interviews with patients were conducted to remove any sources of content-related misconception. Finally, the translated version was applied on patients. All the scales were translated to an easily understandable questionnaire reliable in form and content. An international collaboration aiming to centralise the results has started. Further linguistic validation procedures in other languages have been initiated, and an international cohort structure is planned to be established for body-contouring procedures in order to systematically improve treatment quality in plastic surgery.

A proposal for a tailored approach to diverting ostomy for colorectal anastomosis.

BACKGROUND: The use of a protective stoma represents an important issue in colorectal surgery. Although evidence suggests that loop ileostomy may be superior, the optimal method for temporary decompression of colorectal anastomosis still remains controversial. Aim of this study was to make an evidence-based proposal for a tailored approach to the use of diverting colostomy or ileostomy. METHODS: A retrospective analysis of all patients subjected to creation and closure of a diverting loop colostomy or loop ileostomy between May 2007 and November 2014 in our institution was performed. Early and late complications, mortality and morbidity, time between formation and closure of the stoma in respect to adjuvant chemotherapy and the length of hospital stay were assessed and compared between the two groups. RESULTS: Outcomes of 167 patients (m=95; f=72) undergoing a loop colostomy (N.=130) or ileostomy (N.=37) were analyzed. The most frequent diagnosis was malignancy (64.1%), followed by abdominal emergency operations (18.6%) and complicated diverticular disease (17.4%). There was no mortality. Adjuvant chemotherapy (26.3%) resulted in delayed stoma reversal (P<0.001). Complications following construction of the stoma such as electrolyte disorder (P<0.001), renal insufficiency (P=0.048), and skin irritation (P=0.003) occurred significantly more often within the ileostomy group. Within the colostomy group, the rate of stoma prolapse (P=0.074) tended to be higher. CONCLUSIONS: Both methods have advantages and disadvantages. Loop transverse colostomy could be the preferred technique for older patients to avoid electrolyte disorder and renal insufficiency. Further prospective trials with documentation of electrolyte metabolism and quality of life should follow.

Optimal Positioning of the Nipple-Areola Complex in Men Using the Mohrenheim-Estimated-Tangential-Tracking-Line (METT-Line): An Intuitive Approach.

INTRODUCTION: The reconstruction of the body shape after post-bariatric surgery or high-grade gynecomastia involves, besides skin tightening, the repositioning of anatomical, apparent landmarks. The surgeon usually defines these during the preoperative planning. In particular, the positions of the nipple-areola complexes (NAC) should contribute to the gender-appropriate appearance. While in the female breast numerous methods have been developed to determine the optimal position of the NACs, there are only a few, metric and often impractical algorithms for positioning the nipples and areoles in the male. With this study, we show the accuracy of the intuitive positioning of the nipple-areola complex in men. MATERIAL AND METHODS: From a pre-examined and measured quantity of 10 young and healthy men, six subjects were selected, which corresponded, on the basis of their chest and trunk dimensions, to the average of known data from the literature. The photographed frontal views were retouched in two steps. Initially, only the NACs were removed and the chest contours were left. In a second step, all contours and the navel were blurred. These pictures were submitted to resident and consultant plastic surgeons, who were asked to draw the missing NACs without any tools. The original positions of the nipples were compared with the inscriptions. Furthermore, the results were compared between the contoured and completely retouched pictures and between the residents and consultants. RESULTS: A total of 8 consultants and 7 residents were included. In the contoured and completely retouched images, a significant deviation of the marked positions of the missing features was found. The height of the NAC was determined somewhat more precisely than the vertical position. There was no significant difference between the contoured and completely retouched images, with a discretely more accurate tendency on the contoured images. In comparison with the professional experience, the consultants were tangentially more precise, but without a statistically significant impact. DISCUSSION: The intuitive determination of the NACs is a challenge for the plastic surgeon. In this study, a statistically significant deviation was seen in almost all dimensions, although the clinical relevance cannot be conclusively assessed. We found a positional relationship of the NAC to the infraclavicular groove ("Mohrenheim pit") in the vertical and 4-4.5 cm above the submammary fold. The position of the NAC can be satisfactorily determined by a combination of plastic surgical intuition, patient wishes and practical metric methods using the Mohrenheim-Estimated-Tangential-Tracking-Line (METT-Line).
