Self-Harm Before and Six Months After Obesity Surgery.

Purpose: Previous research on obesity surgery (OS) showed that patients do not only experience weight loss but also improvements in certain mental health outcomes (e.g., depression) after OS.

Postoperative Dumping Syndrome, Health-Related Quality of Life, Anxiety, Depression, and Eating Disturbances: Results of a Longitudinal Obesity Surgery Study.

Introduction: Given the lack of research on the relationship of post-surgery dumping syndrome and eating disturbances, the purpose of the present longitudinal study was to investigate whether dumping after obesity surgery is associated with pre-/postoperative eating disorder symptoms or addiction-like eating beyond the type of surgery, gender, health-realted quality of life (HRQoL) and anxiety/depressive symptoms.

Methods: The study included 220 patients (76% women) before (t0) and 6 months after (t1) obesity surgery (sleeve gastrectomy [n = 152], Roux-en-Y gastric bypass [n = 53], omega loop gastric bypass [n = 15]). The Sigstad Dumping Score was used to assess post-surgery dumping syndrome.

Bariatric Surgery as the One Route to Achieving Donor Heart Transplantation in a Patient with a Left-Ventricular Assist Device.

Bariatric and metabolic surgery is currently the most effective procedure of achieving and maintaining weight loss. In the case under discussion, a 48-year-old male patient with heart insufficiency and an implanted left-ventricular assist device (LVAD) wanted to reduce his high BMI (48.6 kg/m2), so as to qualify for the heart transplant waiting list.

Primary Sleeve Gastrectomy and Leaks: The Impact of Fundus-Wall Thickness and Staple Heights on Leakage-An Observational Study of 500 Patients.

The most feared complication of laparoscopic sleeve gastrectomy (LSG) is staple-line leakage. Staple height and fundus-wall thickness might influence such leakage, and this study examined their possible impact on leak incidence. Factors including gender, age, comorbidities, and reinforcement of the staple line were also investigated.

A rare case of hepatic metastasis 20 years after surgical resection of a thymoma: A case report.

Introduction: Thymoma is the most common solid, primary mediastinal tumour, accounting for 20% of mediastinal neoplasms. Malignant thymus tumours (thymomas and thymic carcinomas) metastasize primarily locally. Distant metastases, especially to liver are very rare.

No addiction transfer from preoperative food addiction to other addictive behaviors during the first year after bariatric surgery.

Objective: The aim of the present study was to investigate whether the remission of preoperative food addiction is associated with increases or new onset of other addictions within the first year following bariatric surgery.

Methods: One hundred and twenty-five bariatric surgery patients were assessed before surgery (t1) and at 6 months (t2) and 1 year (t3) follow-ups. The assessments included the Yale Food Addiction Scale 2.

30-Day Morbidity and Mortality of Bariatric Surgery During the COVID-19 Pandemic: a Multinational Cohort Study of 7704 Patients from 42 Countries.

Background: There are data on the safety of cancer surgery and the efficacy of preventive strategies on the prevention of postoperative symptomatic COVID-19 in these patients. But there is little such data for any elective surgery. The main objectives of this study were to examine the safety of bariatric surgery (BS) during the coronavirus disease 2019 (COVID-19) pandemic and to determine the efficacy of perioperative COVID-19 protective strategies on postoperative symptomatic COVID-19 rates.

Psychosocial Predictors of Work Ability in Morbidly Obese Patients: Results of a Cross-Sectional Study in the Context of Bariatric Surgery.

Background: Obesity is associated with a higher risk of work disability and premature early retirement.

Objective: The aim of this study was to examine psychosocial predictors for work ability prior to surgery.

Methods: Based on a sample of 197 surgery-seeking obese patients (preoperative body mass index [BMI] above 35 kg/m2) from a German bariatric surgery unit, the present cross-sectional study examined based on standardized self-rating measures whether depressive symptoms, dysfunctional eating behaviors, relationship satisfaction, and life satisfaction have a predictive value for work ability.

Correction to: Laparoscopic Sleeve Gastrectomy: Investigation of Fundus Wall Thickness and Staple Height-an Observational Cohort Study Fundus Wall Thickness and Leaks.

There is an error in the published article. One patient's gender was mistaken; it has been changed from female to male. Thus, the number of male and female patients in Tables 1 and 2, and the median and p value in Table 2 are incorrect.

Food addiction and other addictive behaviours in bariatric surgery candidates.

Objective: The present study investigated the association between food addiction (FA) and other addictive behaviours in 216 bariatric surgery candidates (91.7% class 3 obesity; 80.1% women; age Mdn = 44.

Development and Evaluation of the Quality of Life for Obesity Surgery (QOLOS) Questionnaire.

Background And Aim: Even though health-related quality of life (HRQOL) is considered an important component of bariatric surgery outcome, there is a lack of HRQOL measures relevant for preoperative and postoperative patients. The objective of the current study was to develop a new instrument assessing HRQOL prior to and following bariatric surgery, entitled Quality of Life for Obesity Surgery (QOLOS) Questionnaire.

Methods: Topics for the QOLOS were initially generated via open-ended interviews and focus groups with 19 postoperative bariatric surgery patients.

Laparoscopic Sleeve Gastrectomy: Investigation of Fundus Wall Thickness and Staple Height-an Observational Cohort Study : Fundus Wall Thickness and Leaks.

Background: Staple line leakage is a well-known complication after laparoscopic sleeve gastrectomy (LSG). Gastric wall thickness and the staple height may be determining factors for the occurrence of insufficiencies. To investigate this problem, an observational cohort study was carried out.

Health-Related Quality of Life, Anxiety, and Depression in Bariatric Surgery Candidates Compared to Patients from a Psychosomatic Inpatient Hospital.

Background And Aim: Past research indicated high psychiatric comorbidity and poor health-related quality of life (HRQOL) in patients seeking surgical treatment for obesity. This study investigated if preoperative bariatric surgery patients perceive equally poor HRQOL and increased levels of anxiety and depression as mentally ill patients.

Methods: The study included four groups: 192 bariatric surgery candidates (PRE, 71% women, BMI 48.

Quantity-guided drain management reduces seroma formation and wound infections after radical lymph node dissection: results of a comparative observational study of 374 melanoma patients.

Background: Lymphatic fistulas are common complications after lymph node dissections in melanoma patients. We investigated whether drain management could improve the patient's outcome.

Methods: Patients who underwent axillary or inguinal lymph node dissection (RALND or RILND) for malignant melanoma were recorded in a prospective database.

Postoperative surgical complications after radical axillary lymph node dissection in melanoma disease result in increased pain.

Postoperative pain is one of the major problems caused by the operative trauma. We recorded the postoperative pain of patients who underwent a radical axillary lymph node dissection (RALND) to evaluate the quality of our standardized perioperative pain management program and the influence of surgical complications. Between August 2003 and December 2007, we registered the postoperative level of pain of 111 patients who underwent a therapeutic RALND, using a visual analog scale (VAS).

The German registry for natural orifice translumenal endoscopic surgery: report of the first 551 patients.

Objective: To analyze patient outcome in the first 14 months of the German natural orifice translumenal endoscopic surgery (NOTES) registry (GNR).

Summary Background Data: NOTES is a new surgical concept, which permits scarless intra-abdominal operations through natural orifices, such as the mouth, vagina, rectum, or urethra. The GNR was established as a nationwide outcome database to allow the monitoring and safe introduction of this technique in Germany.

Preemptive analgesia reduces pain after radical axillary lymph node dissection.

Background: Analyzing prospective data of our melanoma patients, we registered a suboptimal pain score under mobilization after radical axillary lymph node dissection (RALND). We performed a randomized, double blinded clinical trial to investigate the effects of a preemptive Parecoxib analgesic during the perioperative course.

Materials And Methods: Between October 2006 and December 2007, 32 patients with stage III/IV melanoma underwent therapeutic RALND and were randomized into two groups.

Effects of cyclooxygenase inhibition on anastomotic healing following large bowel resection in a rabbit model--a randomized, blinded, placebo-controlled trial.

Purpose: We performed an experimental study in a rabbit model to investigate the effects of a selective Cox-2 inhibitor (Valdecoxib) on anastomotic healing following large bowel resection after 1 week.

Materials And Methods: Eighty New Zealand white rabbits were randomized into four groups and underwent a colon resection with end-to-end anastomosis. Group 1 (n = 20) was treated with Valdecoxib, group 2 with Metamizole (Novalgin), group 3 with Resveratrol (specific Cox-1 inhibitor), or a placebo vehicle with similar volume (group 4).

Intraoperative application of fibrin sealant does not reduce the duration of closed suction drainage following radical axillary lymph node dissection in melanoma patients: a prospective randomized trial in 58 patients.

Background: Patients suffering from malignant melanoma often require radical lymph node dissection of the axillary nodal basin. The effects of intraoperative application of fibrin sealant following radical axillary lymph node dissection (RALND) on the incidence of postoperative lymphatic secretion are discussed. To study the effect of intraoperatively applied fibrin sealant following RALND a randomized patient-blinded trial was carried out.

The ubiquitin- and proteasome-dependent degradation of COX-2 is regulated by the COP9 signalosome and differentially influenced by coxibs.

The cyclooxygenase-2 (COX-2) enzyme is induced upon inflammation and in neoplastic tissues. It produces prostaglandins that stimulate tumor angiogenesis and tumor growth. Therefore, destruction and/or specific inhibition of COX-2 should be an important aspect of future tumor therapy.

Laparoscopic sigmoidectomy in Germany--a standardised procedure?

Background: Laparoscopic resection of the sigmoid colon is generally considered as feasible option to open surgery, but standardised guidelines on surgical details have not been adopted yet. The aim of this survey was to investigate which techniques were applied by laparoscopic surgeons who are members of the Surgical Working Group for Minimal Invasive Surgery (CAMIC) of the German Surgical Society.

Materials And Methods: In 2005, we conducted a written survey among all members of the CAMIC asking them for their routine surgical strategy of laparoscopic sigmoid resection in a standardised multiple-choice questionnaire.

Re-endothelialization of punctured ePTFE graft: an in vitro study under pulsed perfusion conditions.

Background: When used as arteriovenous (AV) shunts for haemodialysis, small diameter expanded polytetrafluoroethylene (ePTFE) grafts have a high failure rate in vivo. Attempts to improve graft patency are various, and focus on either improvement of implantation techniques or graft tissue engineering. The tissue engineering approach attempts to reproduce in grafts the properties of pristine vasculature.

Intraperitoneal administration of the angiogenesis inhibitor thalidomide does not impair anastomotic healing following large bowel resection in a rabbit model.

The effects of thalidomide after intraperitoneal instillation on the healing of colonic anastomoses are not known. A series of 40 New Zealand White rabbits underwent an end-to-end colonic anastomosis. The animals were randomized into four groups.

Thalidomide given intraperitoneally reduces the number of postoperative adhesions after large bowel resection in rabbits.
