RESUMO

Laparoscopic gastrectomy (LG) using intracorporeal anastomosis has recently become more prevalent due to the advancements of laparoscopic surgical instruments. However, intracorporeally hand-sewn anastomosis (IHSA) is still uncommon because of technical difficulties. In this study, we evaluated various types of IHSA following LG with respect to the technical aspects and postoperative outcomes.Seventy-six patients who underwent LG using IHSA for treatment of gastric cancer between September 2014 and June 2018 were enrolled in this study. We described the details of IHSA in step-by-step manner, evaluated the clinicopathological data and surgical outcomes, and summarized the clinical experiences.Four types of IHSA have been described: one for total gastrectomy (Roux-en-Y) and 3 for distal gastrectomy (Roux-en-Y, Billroth I, and Billroth II). The mean operation time and anastomotic time was 288.7 minutes and 54.3 minutes, respectively. Postoperative complications were observed in 13 patients. All of the patients recovered well with conservative surgical management. There was no case of conversion to open surgery, anastomotic leakage, or mortality.LG using IHSA was safe and feasible and had several advantages compared to mechanical anastomosis. The technique lengthened operating time, but this could be mitigated by increased surgical training and experience.

RESUMO

Importance: Errors and adverse events occur frequently in health care. Three-dimensional (3-D) laparoscopic systems claim to provide more realistic depth perception and better spatial orientation compared with their 2-D counterparts. Objective: To compare the association of 3-D vs 2-D systems with technical performance during laparoscopic Roux-en-Y gastric bypass (LRYGB) procedures using a multiport intraoperative data capture system. Design, Setting, and Participants: This cohort study was performed between May and December 2018, with a total of 50 LRYGB procedures performed in an academic tertiary care center; recordings of the operations were evaluated with a 30-day follow-up. All procedures were performed by the same surgical team. Exposure: Surgical teams used 2-D or 3-D laparoscopic systems. Main Outcomes and Measures: Technical performance was evaluated using the Objective Structured Assessment of Technical Skill and surgical errors and events using the Generic Error Rating Tool. Results: Of the 50 patients who underwent LRYGB procedures, 42 (86%) were women, with a median (interquartile range) age of 42 (35-47) years and a median (interquartile range) body mass index of 46 (42-48), with no significant demographic differences between the groups whose operations were performed using the 2-D and 3-D systems. The mean (SD) number of errors per case was significantly lower in procedures using the 3-D laparoscopic system than in those using the 2-D system (17 [6] vs 33 [2]; P < .001). The mean (SD) number of error-related events was significantly lower in procedures using the 3-D system than in those using the 2-D system (6 [2] vs 11 [4]; P < .001). Mean (SD) Objective Structured Assessment of Technical Skill scores were significantly higher when the 3-D system was used than when the 2-D system was used (28 [4] vs 22 [3]; P < .001). Conclusions and Relevance: In this limited sample of LRYGB procedures, the use of a 3-D laparoscopic system was associated with a statistically significant reduction in errors and events as well as higher Objective Structured Assessment of Technical Skill scores compared with 2-D systems.

RESUMO

Ehlers-Danlos syndrome is a hereditary connective tissue disorder that has gastrointestinal manifestations in over 50% of its cases. We present the first case of bariatric surgery in a patient with Ehlers-Danlos syndrome and outline management challenges in the context of the relevant literature. A 56-year-old man with type IV Ehlers-Danlos syndrome and a body mass index of 41.8 kg/m2 was referred to the bariatric centre of the Churchill Hospital, Oxford, for consideration of surgery for morbid obesity. His comorbidity included type 2 diabetes, hypertension, dyslipidaemia and obstructive sleep apnoea. He underwent a laparoscopic Roux-en-Y gastric bypass. His initial recovery was uneventful and he was discharged on the first postoperative day. Six weeks later, he presented with 43.9% excess weight loss and improved glycaemic control. Three months postoperatively, however, he complained of dysphagia, regurgitation and postprandial pain. A barium meal and gastroscopy suggested the presence of a gastric diverticulum. A surgical exploration was planned. Intraoperative gastroscopy demonstrated an asymmetrical gastric pouch dilatation and the pouch was therefore refashioned laparoscopically. Despite the initial symptomatic relief, two months later he experienced retrosternal pain with progressive dysphagia. Since then, multiple endoscopic dilatations of the gastro-oesophageal junction have been performed for recurrence of symptoms. Finally, a laparoscopic hiatus hernia repair and adhesiolysis was performed resulting in complete relief of patient's symptoms. Bariatric management of patients with Ehlers-Danlos syndrome can prove challenging. The bariatric team must implement a careful management plan including a detailed consent process, a tailored surgical intervention and a follow-up focused on potential gastrointestinal manifestations.

RESUMO

BACKGROUND: Gastrojejunostomy (GJ) tubes are frequently used to provide nutrition in patients who do not tolerate gastric feeding. Despite their widespread use, there is little literature on the lifespan of GJ tubes, reasons for failure, and recommendations for optimal techniques and timing of replacement. We aimed to evaluate the natural history of GJ tubes in pediatric patients. MATERIALS AND METHODS: We reviewed all pediatric patients who underwent GJ tube placement or exchange at our institution from January 2012 to July 2018. Demographic data, time, and indication for replacement or removal of GJ tubes were collected. End points were permanent removal of GJ tube or mortality. RESULTS: Seventy-nine patients underwent 205 GJ tube procedures with a median of 2 GJ tubes per patient. Median GJ tube lifespan was 98 d (interquartile range = 54-166). The two most common indications for tube exchange were structural or mechanical problems (43.1%) and GJ tube dislodgement (34.6%). Although most GJ tube exchanges (66%) were performed under general anesthesia or with moderate sedation, 34% of exchanges were done without sedation. During the study period, 12 patients (15.2%) died from their primary disease, nine patients (11.4%) required subsequent fundoplication, one (1.3%) underwent a jejunostomy, and 23 (29.1%) progressed to gastric feeds without fundoplication at a median time of 208 d. CONCLUSIONS: GJ tubes offer a safe and effective feeding option in patients intolerant of gastric feeding. GJ tubes fail most commonly from intrinsic structural or mechanical issues, and many patients ultimately tolerate gastric feeds without need for further intervention. Exchange of tubes without anesthesia is a viable option.

RESUMO

BACKGROUND: Technical improvement of gastrojejunostomy is critical in bariatric and metabolic surgery. In this study, a novel magnetic compression approach for gastrojejunostomy was evaluated. MATERIALS AND METHODS: Both cylindrical and rectangular magnets were used in rabbits, and the magnets were named according to their location. All the magnets were perorally introduced into the stomach. The position of the jejunal magnet was controlled by a connecting line. When the jejunal magnet spontaneously entered the jejunum, the gastric magnet was introduced into the stomach. An extracorporeal magnet was used to guide these two magnets together, and the magnet pair was left to create a side-to-side anastomosis. The state of the animals and extrusion time of the magnets were observed. The anastomoses were evaluated by burst pressure and histology. RESULTS: Gastrojejunostomy was successfully established in all animals. Cylindrical and rectangular magnets spontaneously entered the jejunum through the pylorus within 2.4 ± 0.5 and 6.0 ± 0.8 d, respectively (P < 0.01). The cylindrical and rectangular magnet pairs fell off within 15.3 ± 0.8 and 11.9 ± 1.1 d, respectively (P < 0.01). The burst pressures were statistically similar between the two types of magnets (P > 0.05). Histological examination showed sealed anastomoses with mild inflammation of the mucosa and fibrosis within the submucosa. CONCLUSIONS: The feasibility and efficacy of establishing gastrojejunostomy by guidewire introduction of magnets, which were guided together with an extracorporeal magnet, were confirmed in rabbits. In humans, with the clinical use of this procedure, surgery would be greatly simplified.

RESUMO

BACKGROUND: The Roux-en-Y gastric bypass (RYGB) surgery helps patients achieve excellent excess weight loss, with subsequent improvement or resolution of co-morbidities. However, up to 20% of all RYGB patients, and 40% of the super morbidly obese, experience significant weight regain. The etiology of weight regain is multifactorial; hence, multidisciplinary management is mandatory. Revision options for failed conservative and medical management include resizing the restrictive component of the bypass or intensifying malabsorption. While improvement of restriction generally has limited efficacy, intensifying malabsorption achieves significant long-term excess weight loss. The optimal surgical option should be personalized, considering eating behavior and psychological issues, surgical anatomy of the bypass, and anesthetic and surgical risks.

RESUMO

Objective: The development of these updated clinical practice guidelines (CPGs) was commissioned by the American Association of Clinical Endocrinologists (AACE), The Obesity Society, American Society of Metabolic and Bariatric Surgery, Obesity Medicine Association, and American Society of Anesthesiologists Boards of Directors in adherence with the AACE 2017 protocol for standardized production of CPGs, algorithms, and checklists. Methods: Each recommendation was evaluated and updated based on new evidence from 2013 to the present and subjective factors provided by experts. Results: New or updated topics in this CPG include: contextualization in an adiposity-based chronic disease complications-centric model, nuance-based and algorithm/checklist-assisted clinical decision-making about procedure selection, novel bariatric procedures, enhanced recovery after bariatric surgery protocols, and logistical concerns (including cost factors) in the current health-care arena. There are 85 numbered recommendations that have updated supporting evidence, of which 61 are revised and 12 are new. Noting that there can be multiple recommendation statements within a single numbered recommendation, there are 31 (13%) Grade A, 42 (17%) Grade B, 72 (29%) Grade C, and 101 (41%) Grade D recommendations. There are 858 citations, of which 81 (9.4%) are evidence level (EL) 1 (highest), 562 (65.5%) are EL 2, 72 (8.4%) are EL 3, and 143 (16.7%) are EL 4 (lowest). Conclusion: Bariatric procedures remain a safe and effective intervention for higher-risk patients with obesity. Clinical decision-making should be evidence based within the context of a chronic disease. A team approach to perioperative care is mandatory, with special attention to nutritional and metabolic issues.

RESUMO

BACKGROUND: In high-income countries, morbid obesity is a growing health problem that has already reached epidemic proportions. When performing a laparoscopic gastric bypass several operative methods exist. AIM: To describe the institutional experience using a knotless unidirectional barbed suture (V-Loc 180/Covidien, Mansfield, MA) to create a hand-sewn gastrojejunostomy (GJ) and jejunojejunostomy (JJ) during bariatric surgery. METHODS: Evaluation of a case series of 87 morbidly obese patients who underwent laparoscopic gastric bypass with a hand-sewn gastrojejunostomy (GJA) and jejunojejunostomy (JJA) between 01/2015 and 06/2017. The patients were divided into two groups: in group I, GJA und JJA sutures were performed using the knotless unidirectional barbed suture; in group II, GJA and JJA were sutured with resorbable multifilament thread (Vicryl® 3/0 Ethicon, Livingstone, UK). The recorded data on gender, age, BMI, ASA score, operative time, postoperative morbidity, length of hospital stay, and reoperation, were analyzed and compared. RESULTS: All procedures were completed laparoscopically with no mortality. The mean operative time was 123.23 (±30.631) in group I and 127.57 (±42.772) in group II (p<0.05). The postoperative complications did not differ significantly between the two groups. Early complications were observed for two patients (0.9%) in the barbed suture group and for one patient (0.42%) in the multifilament suture group (p<0.05). In group I two patients (0.9%) required reoperation: on the basis of jejunojejunal stenosis in one patient, and local abscess near the gastrojejunostomy, without a leakage, in the other. In group II one patient (0.42%) required reoperation due to stenosis of the GJA. The duration of hospital admission was similar for both groups: 3.36 (±0.743) days in group I vs. 3.38 (±1.058) days in group II (p<0.05). CONCLUSION: The novel anastomotic technique is a safe and effective method and can be applied to gastrojejunal anastomosis and jejunojejunal anastomosis in laparoscopic gastric bypass.

RESUMO

BACKGROUND: : Bariatric surgery promotes significant weight loss and improvement of associated comorbidities; however, nutrients deficiencies and weight regain may occur in the middle-late postoperative period. AIM: To investigate nutritional status in 10 years follow-up. METHODS: : Longitudinal retrospective study in which anthropometric, biochemical indicators and nutritional intake were assessed before and after one, two, three, four, five and ten years of Roux-en Y gastric bypass through analysis of medical records. RESULTS: : After ten years there was a reduction of 29.2% of initial weight; however, 87.1% of patients had significant weight regain. Moreover, there was an increase of incidence of iron (9.2% to 18.5%), vitamin B12 (4.2% to 11.1%) and magnesium deficiency (14.1% to 14.8%). Folic acid concentrations increased and the percentage of individuals with glucose (40.4% to 3.7%), triglycerides (38% to 7.4%), HDL cholesterol (31 % to 7.4%) and uric acid (70.5% to 11.1%) abnormalities reduced. Also, there is a reduction of food intake at first year postoperative. After 10 years, there was an increase in energy, protein and lipid intake, also a reduction in folid acid intake. CONCLUSIONS: : Roux-en Y gastric bypass is an effective procedure to promote weight loss and improve comorbidities associated with obesity. However, comparison between postoperative period of five and 10 years showed a high prevalence of minerals deficiency and a significant weight regain, evidencing the need for nutritional follow-up in the postoperative period.

RESUMO

In patients undergoing bariatric surgery, the presence of metabolic syndrome (MetS) contributes to perioperative morbidity. We aimed to evaluate the utilization and outcome of severely obese patients with MetS who underwent laparoscopic sleeve gastrectomy (LSG) versus laparoscopic Roux-en-Y gastric bypass (LRYGB). Using the 2015 and 2016 Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program database, data were obtained for patients with MetS undergoing LSG or LRYGB. There were 29,588 MetS patients (LSG: 58.7% vs LRYGB: 41.3%). There was no significant difference in 30-day mortality (0.1% for LSG vs 0.2% for LRYGB, adjusted odds ratio (AOR) 0.58, confidence interval (CI) 0.32-1.05, P = 0.07) or length of stay between groups (2 ± 2 for LSG vs 2.2 ± 2 days for LRYGB, P = 0.40). Compared with LRYGB, LSG was associated with significantly shorter operative time (78 ± 39 vs 122 ± 54 minutes, P < 0.01), lower overall morbidity (2.3% vs 4.4%, AOR 0.53, CI 0.46-0.60, P < 0.01), lower serious morbidity (1.5% vs 2.3%, AOR 0.64, CI 0.53-0.76, P < 0.01), lower 30-day reoperation (1.2% vs 2.3%, AOR 0.52, CI 0.43-0.63, P < 0.01), and lower 30-day readmission (4.2% vs 6.6%, AOR 0.62, CI 0.55-0.69, P < 0.01). In conclusion, LSG is the predominant operation being performed for severely obese patients with MetS, and its popularity may in part be related to its improved perioperative safety profile.

RESUMO

Bariatric surgery is more effective in the management of morbid obesity and related comorbidities than conservative therapy. There are two main groups, restrictive and malabsorptive procedures. Laparoscopic gastric plication with pylorus-preserving loop duodenoileal bypass is classified into the latter group. It should be considered as the modernized variant of the classical Scopinaro procedure. In this article, the method is presented by a case report. Orv Hetil. 2019; 160(43): 1714-1718.

RESUMO

The prevalence of overweight and obesity has exploded in the post-industrial era. Life style interventions like dieting and exercise can induce a marked weight loss, but the main problem for most patients is to maintain the reduced body weight over time. Gastric bypass surgery is a commonly performed and very effective method for achieving a pronounced and sustained weight loss including metabolic improvements in obese patients. Despite the therapeutic successfulness there are known side-effects like chronic postprandial nausea and pain that in some patients become intractable. The pathophysiology is complex and partly unexplored. The physician or surgeon handling a patient with "post-bariatric symptoms" must be aware of the risk for symptom aggravations due to iatrogenic opioid-associated intestinal dysmotility. The present paper gives a brief overview of obesity surgery and its associated postsurgical conditions with a focus on the unexplored role of the Roux-limb following gastric bypass surgery.

RESUMO

Gastroesophageal reflux disease (GERD) is common in the morbidly obese population, and hiatal hernias are encountered in 20% to 52% of patients. Primary surgical repair of hiatal hernias, in particular the paraesophageal type, is associated with a higher recurrence rate in obese patients. Concomitant weight loss surgery may be advisable. Combined sleeve gastrectomy and paraesophageal hiatal hernia repair is feasible but can induce or worsen preexisting GERD. A Roux-en-Y gastric bypass offers advantages of more pronounced excess weight loss and better symptom control, albeit with a potentially higher rate of morbidity compared with paraesophageal hernia repair alone or sleeve gastrectomy.
