Maintaining quality of life after major lung resection for carcinoid tumor.

BACKGROUND: Pulmonary carcinoid is a rare diagnosis with surgery remaining the standard treatment of choice. However, resection may impact patients' daily activities due to decreased lung volume reserve and postoperative pain. Our study aims to compare the impact of different types of surgical resection on the post-operative quality of life with the application of a strict peri-operative pulmonary care program. METHODS: Patients who underwent surgery for bronchopulmonary carcinoid tumors in a tertiary cancer center between August, 2017 and March, 2020 were identified and demographic data was collected. Patients were contacted via phone for the qualitative and quantitative assessment of pain and quality of life, utilizing the Arabic version of Short-form McGill Pain Questionnaire and Activity of Daily Living (ADL) instrument respectively. Lung reserve was assessed before and after surgery. Statistical analysis used Chi-Square for categorical variables and ANOVA for continuous variables. RESULTS: A total of 16 patients underwent different type of resection. The majority were male (n = 10; 63%) with a mean age of 44 years (19-81). Most common clinical stage was stage I (n = 12, 75%) with typical carcinoid features recorded in more than half of the cases (n = 11, 69%). Almost all patients underwent surgical excision (n = 15, 94%) with negative resection margin and no major post-operative complications. Bilobectomy was the most frequent procedure (n = 6, 40%) and video-assisted thoracoscopic surgery (VATS) was utilized in 8 patients (50%). Expected changes were recorded in pre- and postoperative pulmonary function test with an average drop of 10 in FEV1 and 14 mL/min/mmHg in DLCO. The majority of patients (n = 15, 94%) were totally independent doing daily activities. Mild intermittent pain was found in 7 patients (44%) who scored an average intensity of 1.6 out of 10. CONCLUSIONS: Excellent long-term outcomes can be achieved following surgical resection of pulmonary carcinoid tumors with little to no effect on patients' lung function and quality of life in regard to performance status and post-operative pain when a good peri-operative pulmonary, physical rehabilitation, and pain management programs are adopted and strictly implemented.

Locally advanced thymoma; does neoadjuvant chemotherapy make a difference?

BACKGROUND: Regardless of its rare occurrence, Thymoma remains the most frequently encountered primary tumor of the anterior mediastinum comprising about 50% of all masses in the region. Surgical resection, via thymectomy, remains the mainstay treatment modality. In locally advanced and borderline resectable tumors, neoadjuvant chemotherapy (NACT) may be utilized to increase the chance of R0 resection, raising the question of its efficacy and safety. METHODS: Demographic and clinical data from patients who presented to a tertiary cancer center between January 2015-October 2021 with a diagnosis of thymoma and underwent curative surgical resection was collected. Computed tomography scan was used to delineate clinical staging, tumor size and to detect post-therapeutic variations in tumor burden. The response evaluation criteria in solid tumors (RECIST) was used to classify the effect of NACT on tumor burden. The pathological response was determined by measuring the percentage of necrotic tissue. RESULTS: A total of 23 patients were diagnosed with thymoma. Most patients were male with a mean age 46 (± 15) years at diagnosis. The most common clinical stage was stage II with 5 patients (22%). A total of 12 patients had NACT as compared to 11 patients who had upfront surgery. The mean change in tumor volume was 165 cm3 (p = 0.079) and the change in and maximum diameter was 1.53 ± 1.49 cm (p < 0.01). The effect of NACT on tumor burden based on RECIST criteria was minimal as 8 patients had stable disease. Based on pathological findings, the average necrotic portion of the tumor was 39.5% (p = 0.152). The overall survival rate is 95.65%, mean survival was 115 months (4-125). Recurrence occurred in 5 patients. The NACT group had a higher risk for recurrence (4; 33.3%) with a mean survival of 43.8 months compared to 59.6 months in those who did not receive induction therapy. CONCLUSIONS: The exact role of induction chemotherapy in locally advanced thymoma patients remains controversial. NACT effect after utilizing radiological and pathological assessment tools was not found to significantly improve oncological outcomes compared to upfront surgery in locally advanced disease, with minimal radiologic and pathologic effect. To further demonstrate the impact of induction chemotherapy, we recommend multicentric collaborative studies.

Unusual Acute, Massive Lower Gastrointestinal Bleeding Secondary to a Proximal Jejunal Gastrointestinal Stromal Tumor: A Case Report.

The most common primary non-epithelial neoplasms of the gastrointestinal (GI) tract are gastrointestinal stromal tumors (GISTs). Ten percent (10%) of GISTs arise from the jejunum. Usually, patients complain of abdominal discomfort, but they may present with complications such as intestinal obstruction or bleeding. This report describes a 35-year-old male who presented with unusually massive, acute lower GI bleeding. After resuscitation and investigations (including a contrast-enhanced computed tomography of the abdomen and lower GI endoscopy), the patient underwent diagnostic laparoscopy and bowel resection of the affected section with anastomosis, and he had an eventful postoperative course. Studies suggest that GI bleeding in GIST occurs due to the ulceration and necrosis of the overlying mucosa caused by the pressure effect of the mass. Small-bowel GISTs are categorized based on their size. Many guidelines have advocated conservative management for small GISTs (<2 cm) that are in the jejunum. This patient has a rare case of a small jejunal GIST with a rare presentation of massive lower GI bleeding. A multidisciplinary approach is useful in managing such cases, and our case showed that laparoscopic intervention is a feasible option in a stable patient with massive lower GI bleeding.

Comparative Study Between Silver Nanoparticles Dressing (SilvrSTAT Gel) and Conventional Dressing in Diabetic Foot Ulcer Healing: A Prospective Randomized Study.

BACKGROUND: We are trying to evaluate silver nanoparticles' effectiveness (SilvrSTAT Gel) in accelerating healing rate of nonischemic diabetic foot ulcers (DFUs). METHODS: This prospective, double-blind, randomized, controlled study includes 80 patients with nonischemic DFUs classified into 2 groups. Group A was subjected to SilvrSTAT Gel dressing, and group B was subjected to conventional dressing (wet-to-moist dressing with or without povidone-iodine). All cases had minimal debridement before treatment. In both groups, all cases were nonischemic after successful revascularization either by bypass surgery or endovascular therapy. RESULTS: The healing rate of the SilvrSTAT group was significantly higher than that of the conventional group. The healing rate per week of the SilvrSTAT group was considerably higher than that of the conventional group (P < .0001). The rate of complete healing for ulcers in group A was achieved in 22 patients (55%) by the 6th week, while 29 (72.5%), 34 (85%), and 36 (90%) patients were healed entirely by the 8th, 10th, and 12th weeks, respectively. In group B: 20 (50%), 27 (67.5%), and 30 (75%) patients were completeley healed by the 8th, 10th, and 12th weeks, respectively. CONCLUSIONS: SilvrSTATGel is effective in the treatment of DFU.

Effects of biophilic virtual reality on cognitive function of patients undergoing laparoscopic surgery: study protocol for a sham randomised controlled trial.

INTRODUCTION: Virtual reality (VR) is already being used for cognitive or emotional rehabilitation. However, its role in postoperative cognitive dysfunction (POCD) has not been fully recognised. Due to the lack of an effective postoperative follow-up system, the incidence of POCD in China is not clear, and although many drugs have been proposed to improve POCD in the animal study, their clinical applications are limited, while VR provides an innovative method to provide non-pharmacological management. METHODS AND DESIGN: This is a single-centre, randomised, double-blind, sham-controlled clinical trial. In this study, 600 patients over 55 years old undergoing laparoscopic surgery will be recruited. Participants will be randomly assigned to receive biophilic VR or sham VR (1:1 ratio), all patients have 20 min of exposure per day during the hospital stay. The primary outcome is the impact of VR on the incidence of POCD. Secondary outcomes include perioperative anxiety and instrumental activities of daily living. Changes in the performance of the neurocognitive batteries are measured by a local resident doctor. Serum samples will be collected on the day before surgery and 7 days after surgery. ETHICS AND DISSEMINATION: This trial has ethical approval from the Medical Ethics Committee of the Affiliated Hospital of Medical School of Ningbo University (KY20210302). The study is sponsored by Ningbo University and Ningbo Science and Technology Bureau. CONTACT: Dr. Mao Haijiao, Chair of the hospital medical Ethics committee (ndfylunli@126.com). Trial results will be submitted for publication in peer-reviewed journals, patient recruitment began in April 2021. Written informed consent is obtained for all participants. All information acquired will be disseminated via national or international conferences and published in peer-reviewed journals. TRIAL REGISTRATION NUMBER: ChiCTR2000040919.

2021 NATIONAL DIAGNOSTIC REFERENCE LEVELS FOR PAEDIATRIC COMPUTED TOMOGRAPHY IN EGYPT.

OBJECTIVE: To establish national diagnostic reference levels (NDRLs) for most common paediatric computed tomography (CT) examinations in Egypt. METHODS: This was a prospective study that included all dedicated paediatric imaging centers in Egypt. Data from 1680 individual paediatric patients undergoing CT scanning of the head, chest and abdomen-pelvis were collected. Computed tomography dose indices were recorded, data were analysed and compared with the internationally published paediatric DRLs in14 countries. RESULTS: The Egyptian NDRLs of the CTDIvol (mGy) for head, chest and abdomen-pelvis scans among four paediatric age groups were found to be (23, 27, 28, 32, 4, 5, 6, 8, 5, 6, 7, 9) mGy, respectively; and the corresponding NDRLs of the DLP (mGycm) for head, chest and abdomen-pelvis scans were found to be (345, 428, 499, 637, 67, 85, 145, 215, 97, 135, 240, 320) mGycm, respectively. There were variations in the radiation doses between CT centers and identical scanners indicating the need for dose optimization. The NDRLs of the CTDIvol (mGy) and the DLP (mGycm) values were similar to or lower than international DRLs. CONCLUSION: This study summarizes the results of the first Egyptian Computed Tomography survey that provides national diagnostic reference levels for paediatric patients in Egypt. Despite the reasonable NDRLs values, the study depicted certain pros and cons concerning CT practice, and identified some problems that hinder the process of optimization as well as justification in children.

Prevalence and determinants of refractive error and related ocular morbidities among Saudi adolescence population in Riyadh, Saudi Arabia.

PURPOSE: The purpose of this study was to determine the magnitude and determinants of refractive error (RE) and related ocular morbidities among preparatory and secondary Saudi students in Riyadh. METHODS: This study was conducted in 2017-2018 at preparatory (12-14 years) and secondary (15-18 years) schools. A "Spot Screener" was used to determine if the child passed or failed a refraction test. Fail test meant RE ≥ ± 0.50 D. Data were collected on refractive status in each eye, anisometropia, and strabismus. The type of RE was estimated and analysis was performed for an association to gender, age, and education levels. The use of spectacle while screening defined the compliance of spectacle wear. RESULTS: The study sample was comprised of 708 Saudi students. There were 59.5% of boys. The prevalence of RE was 43.6% (95% confidence interval [CI]: 40.0, 47.3). The prevalence of RE in preparatory and secondary students was 44.5% and 43.2%, respectively. The proportion of myopia (≥ -0.5 D) and hyperopia (≥ +0.5 D) among students with RE was 82.2% and 17.8%, respectively. Family history of RE was positively associated to RE in students (odds ratio: 1.8 [95% CI: 1.3, 2.5]). The current screening initiative identified 45 (6.4%) new cases of RE who required spectacles. The compliance rate for using visual aid among students with RE was 74.6%. The prevalence of anisometropia and strabismus was 3.0% and 4.1%, respectively. CONCLUSIONS: A high proportion of Saudi adolescence in Riyadh have RE. Periodic ophthalmic assessment and refractive services are recommended as part of school health screening initiatives.

An Evaluation of the Usefulness of YouTube® Videos on Crown Preparation.

BACKGROUND: You Tube is one of the most commonly used online sources for sharing information and knowledge. Academic topics or clinical data shared on this platform is not peer reviewed or evaluated by subject specialists for accuracy. No study was found in the literature examining the validity of crown preparation videos available at this platform. OBJECTIVE: To evaluate the authenticity of the content and quality of the crown preparation videos uploaded on the YouTube. METHODS: The systematic search for YouTube videos was carried out over a period of one year from January 2020 until February 2021. The keywords or phrases and tags used were crown preparation, PFM crown preparation, all ceramic crown preparation, and dental crown preparation. The videos were shortlisted on the basis of inclusion and exclusion criteria to select educationally useful videos in terms of content and quality. RESULTS: Three subject specialists evaluated the videos on crown preparation three times to shortlist only 12 (11%) educationally useful videos out of 109 relevant videos. These 12 videos met the preset inclusion criteria. CONCLUSION: Although YouTube is the most popular social media platform used as the source of information by the students, the majority of uploaded content lacks authenticity. This study found that crown preparation videos uploaded by the faculty members or subject specialists can be considered as the reliable source.

Sleep Monitoring of Children With Nocturnal Enuresis: A Narrative Review.

The purpose of this article is to provide a succinct summary of the sleep monitoring efforts that have been used in nocturnal enuresis (NE) and an overview of the knowledge that has accrued. This is not intended to be a comprehensive review, but rather is intended to highlight how polysomnography (PSG), a common sleep detection tool, has contributed to our understanding of NE, as arousal disorder is considered to be one of the important mechanisms. The authors have organized this report by analysis and display of different ingredients of PSG, starting with comparing the electroencephalogram (EEG) of controls and the enuretic children and then moving to evaluation of respiratory patterns of NE and comorbid disease obstructive sleep apnea (OSA). In addition, the authors' goal is to better understand the mechanism of NE by integrating various levels of sleep monitoring; those sleep-related clinical scale scores for NE are presented to date. Finally, we propose further research of NE to explore the microstructure alterations via PSG combined with EEG-fMRI or to use novel technology like portable device internet and deep learning strategy.

Groin abscess, a rare complication of strangulated femoral hernia: Case report.

Femoral hernias account for 8%-11% of all groin hernias and 3%-5% of all anterior abdominal wall hernias. While groin hernias are more common in males, femoral hernias are developed more commonly in female, accounting for 22%-34% of all groin hernias compared with 1.1% in male. The lifetime risk of developing groin hernia in male is approximately 25% but in female less than 5%, so in all female patients with groin hernias, femoral hernias should be included in the differential diagnosis until proven otherwise. The main concern of a femoral hernia is the higher risk of bowel strangulation, presenting emergently in 32%-39% of patients. We report a case of strangulated femoral hernia in a 78-year-old female who was presented to emergency department with groin abscess based on ultrasound image; patient was then diagnosed as having strangulated femoral hernia and taken to the operating theater, where she was found having strangulated segment of small intestine, so the patient underwent bowel resection and anastomosis with repair of the defect extraperitoneally, and ultimately, the patient improved and discharged from the hospital. Strangulated femoral hernia can present with groin abscess. Furthermore, femoral hernia should be ruled out in elderly patient presented with groin abscess, especially female patients.

Role of perioperative parathormone hormone level assay after total thyroidectomy as a predictor of transient and permanent hypocalcemia: Prospective study.

BACKGROUND: The researchers are trying to evaluate the measurement of: Intact parathyroid hormone (iPTH) and serum total calcium (sCa) levels for predicting hypocalcemia after total thyroidectomy (TT). METHODS: The sample of this single center prospective study consists of (100) patients, where (77) females and (23) males with an age range between (28) and (65) (the mean level is, 48.17 ± 6.54). These selected patients underwent total thyroidectomy (TT) in the general surgery department, Benha university hospital from the period of June 2019 to February 2020. Levels of sCa and iPTH were measured aat several times preoperatively, 10 min, 48 h, 3, 6, 9 months, and 1 year after being after gone TT. RESULTS: Among the entire study sample, 23 patients (23%) developed transient hypoparathyroidism and hypocalcemia (˂8.5 mg/dl), none of them developed permanent hypoparathyroidism and hypocalcemia. The cut-off point of PTH has been 10 min after TT was at 23 pg/mL as it was the best compromise between sensitivity and specificity for predicting hypocalcaemia. It has been found that Patients who have a PTH greater than 23 pg/mL can be discharged safely after 24 h. Patients who have PTH of less than 23 pg/mL were observed for an additional 24 h, and the study found that timely treatment initiation is recommended. A PTH ˂ 10 pg/mL measured at 48 h after surgery had a sensitivity, specificity as well as an accuracy of 100%, for predicting hypocalcemia after TT. The accuracy of a single PTH concentration at 48 h was useful for predicting hypocalcemia [Area under receiver-operator characteristic curve (AUC) 1; confidence interval (CI), 95%, 0.85-0.94]. CONCLUSION: Patients with iPTH ˂ 10 pg/mL, and sCa levels ˂ 7.4 mg/dL are at higher risk of developing hypoparathyroidism and hypocalcemia after TT.

Neuropsychological Tests in Post-operative Cognitive Dysfunction: Methods and Applications.

Post-operative cognitive dysfunction (POCD) is a neurological complication that relatively frequently occurs in older people after anesthesia/surgery, with varying durations and significant differences in the severity of cognitive impairment. POCD is mainly characterized by memory loss mostly without consciousness disorders, accompanied by abnormal emotions, behaviors, and language, mostly without consciousness disorder. The clinical performance of POCD lacks specificity but can reflect the severity of cognitive impairment in patients. The diagnosis of POCD cannot be separated from the evaluation of perioperative cognitive function of patients, and the more popular and accepted method is neuropsychological tests (NPTs).

Feasibility and impact of laparoscopic sleeve gastrectomy after renal transplantation on comorbidities, graft function and quality of life.

BACKGROUND: The aim of this study is to clarify the feasibility and effect of laparoscopic sleeve gastrectomy (LSG) on comorbidities, graft function and quality of life in patients who underwent renal transplantation (RT). METHODS: This is a retrospective review of five patients who underwent LSG after RT. Demographic data, anthropometric parameters, the effect on comorbidities, postoperative course, immunosuppressive medications, causes of RT, renal function, the survival of graft, and quality of life after SG in obese patients with a history of RT were assessed using BAROS-Moorhead-Ardelt survey RESULTS: From September 2015 to September 2019, 5 renal transplant patients underwent LSG; three female, and two male. Median body mass index (BMI) decreased from 42.17 kg/m2 (range 36-55) before surgery to 28.16 kg/m2 (range 25-42) after surgery. Improvement in blood pressure, triglyceride, and cholesterol levels was observed, and all cases were able to decrease their medications. Insulin was stopped and replaced with linagliptin in all diabetic patients. Graft function improved, and proteinuria level decreased in all cases. All patients reported to have an excellent quality of life. CONCLUSION: LSG showed excellent outcomes in this high-risk group of patients regarding comorbidities, graft function and quality of life.

Incidence of Silent Deep Venous Thrombosis after Laparoscopic Bariatric Surgery in Patients Who Received Combined Mechanical and Chemical Thromboprophylaxis Compared to Patients Who Received Mechanical Thromboprophylaxis Only.

Background. This prospective randomized study compares the incidence of silent deep venous thrombosis (DVT) among 2 groups of patients who underwent laparoscopic bariatric surgery. The first group received mechanical thromboprophylaxis only, while the second group received a combination of mechanical and chemical thromboprophylaxis. Methods. This study included 150 morbidly obese patients who underwent primary one-stage laparoscopic bariatric surgery (sleeve gastrectomy and mini-gastric bypass) over a 6-month period. Patients were randomly assigned to 2 groups: group A (n = 75) was subjected to mechanical thromboprophylaxis in the form of perioperative elastic stockings on both lower limbs and early postoperative ambulation, and group B (n = 75) was subjected to combined mechanical thromboprophylaxis and chemical thromboprophylaxis in the form of 40 mg subcutaneous enoxaparin 12 hours before surgery and postoperative enoxaparin (40 mg subcutaneous every 24 hours) for 2 weeks. Bilateral lower limb venous duplex was done for all patients before discharge, on the second and fourth weeks postoperatively, to detect silent DVT. Results. Nine patients out of 150 patients developed silent DVT (6%). All patients among group A were subjected to mechanical thromboprophylaxis only (12%) [P = .247, relative risk: .45, 95% confidence interval; .37-.62]. There was no silent DVT among group B who received combined mechanical and chemical thromboprophylaxis. No bleeding complications were reported in both groups. Conclusion. Combined mechanical and mechanical thromboprophylaxis is effective and safe in the prevention of silent DVT after laparoscopic bariatric surgery. Trial registration: The trial was registered in the Thai Clinical Trials Registry (TCTR20200127002) on January 20, 2020 retrospectively.

A Novel Homozygous Frameshift Variant in DYM Causing Dyggve-Melchior-Clausen Syndrome in Pakistani Patients.

Background: Dyggve-Melchior-Clausen syndrome (DMC) is a skeletal dysplasia with associated defects of brain development and intelligence. The truncating pathogenic variants in DYM are the most frequent cause of DMC. Smith-McCort (SMC), another skeletal dysplasia, is also caused by non-synonymous DYM variants. Methods and Results: In the current study, we examined a Pakistani consanguineous family with three affected members. Clinical features like spondyloepimetaphyseal dysplasia, indicative of characteristic skeletal abnormalities, and intellectual disability were observed. Our male patients had microcephaly and coarse facial features while the female patient did not represent microcephaly or abnormal facies, which are significant features of DMC patients. Sanger sequencing identified a novel homozygous frameshift insertion (c.95_96insT, p.W33Lfs*14) in DYM, which likely leads to nonsense-mediated decay (NMD). Conclusion: The novel frameshift change verifies the fact that pathogenic variants in DYM are the most frequent cause of DMC.

Porto-mesenteric vein thrombosis following laparoscopic sleeve gastrectomy for morbid obesity: Case series and literature review.

BACKGROUND: Portal vein thrombosis is a rare and a potentially lethal complication of Laparoscopic sleeve gastrectomy. In this series, we describe the presentation, treatment, and outcome of 5 cases of PMVT post-laparoscopic sleeve gastrectomy (LSG) treated successfully at our hospital. CASE REPORT: Five patients presented to our emergency department with diffuse abdominal pain associated with anorexia, nausea and vomiting after laparoscopic sleeve gastrectomy (LSG). Computed tomography (CT) scan showed evidence of portal, mesenteric and splenic vein thrombosis and small bowel ischemia in three patients. Two patients were treated only with anticoagulant and the other three patients were treated with surgery in the form of diagnostic laparoscopy converted to laparotomy with Small bowel resection. CONCLUSION: Portal and mesenteric venous thrombosis after laparoscopic sleeve gastrectomy is an unusual complication but it has life threatening consequences if it is not diagnosed early and treated adequately. The patients with porto-mesenteric venous thrombosis (PMVT) usually present themselves with vague abdominal symptoms. As so, the physicians should have high index of suspicion to recommend computed tomography (CT) abdomen to confirm diagnosis and start adequate treatment.

Laparoscopic Duodenojejunostomy for Superior Mesenteric Vein Syndrome Associated with Nutcracker Phenomenon: The First Case Report.

BACKGROUND Duodenal compression between the superior mesenteric vessels and aorta or its branches is a rare disease in which the angle between the superior mesenteric vessels and aorta becomes acute, resulting in duodenal obstruction. Reduction in retroperitoneal fat due to several debilitating conditions is considered to be the cause of the decreased angle between the 2 vessels. Nutcracker phenomenon is the asymptomatic compression of the left renal vein (LRV) between the aorta and the superior mesenteric artery. CASE REPORT We report the case of a 33-year-old man who presented with postprandial abdominal pain, mainly at the epigastric region, colicky in nature, without radiation, accompanied by nausea, postprandial vomiting, and loss of weight. Computed tomography (CT) of the abdomen showed duodenal compression between the SMV and the right common iliac artery, which has never been reported before. Laparoscopic duodenojejunostomy was performed. CONCLUSIONS Vascular compression of the duodenum presents with manifestations of proximal small bowel obstruction, which may have chronic, intermittent, or acute symptoms. Diagnosis is difficult due to the lack of knowledge of this rare disorder. Most of these symptoms can be present in other diseases, and symptoms sometimes do not correspond with imaging findings. Therefore, for a better outcome, the clinician should have a high index of suspicion and should be able to exclude other causes with similar manifestations.

Persistent Hiccups After Cervical Epidural Steroid Injection.

BACKGROUND Hiccup is a rare complication after a cervical epidural steroid injection used in the treatment of chronic pain. A few studies have reported on the physiological and pharmacological aspects of hiccups after epidural steroid injection and there have been some case reports published. Our presented case report provides insight into the side effect of hiccups that can occur in association with cervical epidural analgesia, and will help inform anesthesiologist about this unpleasant complication. CASE REPORT We present a rare case of persistent hiccups after a cervical epidural steroid injection in a 60-year-old male patient with chronic pain due to disc protrusion in C3-C7. CONCLUSIONS Persistent hiccups after epidural injection is a serious complication. As the exact mechanism of hiccups is not yet known, regardless the level of epidural or the mixture of drugs used, and the incident of hiccups after epidural injection is not well-reported, we think that the etiology and the incident rate must be further evaluated.

Preceptorship and proctorship as an effective way to learn laparoscopic sleeve gastrectomy.

BACKGROUND: Laparoscopic sleeve gastrectomy has rapidly gained popularity as a procedure for morbidly obese patients. The goal of this project is to evaluate a training program for the laparoscopic sleeve gastrectomy (LSG), given to a group of surgeons by a specialized consultant in bariatric surgery. METHODS: The training process is divided in two parts. First, bringing the trainee surgeons to a specialized bariatric center to observe and take part in bariatric procedures with an experienced bariatric surgeon (preceptorship). Second, the consulting surgeon offers on-site training to all surgeons within their own hospital (proctorship). The support personnel (bariatric nurse, OR nurse, nutritionist) accompany the surgeon and are included in the training process. Finally, preoperative, intraoperative and postoperative data are compiled and analyzed. RESULTS: This study included 31 patients operated for LSG by the two newly trained surgeons after proctorship. Median age was 43 and mean BMI was 45.9. No leak, stricture, or mortality was found after the surgery. Mean surgical time was 94 min, and mean hospital length of stay was 3.9 days. Minor complications were seen during the follow-up at 1 to 3-6 months with excessive weight loss (EWL) of 62 % at 6 month. CONCLUSIONS: This study showed the effectiveness of training provided through preceptorship/proctorship with a specialized consulting surgeon. The low complication rate and the weight loss achieved in only 6 months demonstrate the safety and efficacy of this learning method.
