Gastric bypass complications

OBJECTIVE: To evaluate the short-term outcomes of mechanical and hand-sewn laparoscopic one-anastomosis mini-gastric bypass. MATERIAL AND METHODS: There were 233 patients who underwent laparoscopic one-anastomosis mini-gastric bypass. Short-term results were analyzed in groups of mechanical (the first group, n =108) and hand-sewn (the second group, n =125) gastrojejunostomy. No significant between-group differences in baseline data were detected (demographic characteristics, body mass index, comorbidity and previous abdominal surgeries)...

Bariatric surgery is a commonly performed procedure for patients who have failed to achieve weight loss through medical and lifestyle interventions. However, the altered gastrointestinal anatomy resulting from the surgery can significantly impact the bioavailability of antidepressants in patients with generalized anxiety disorder, potentially leading to uncontrolled anxiety symptoms. This case report describes a patient with generalized anxiety disorder who underwent Roux-en-Y gastric bypass surgery and subsequently experienced increased anxiety symptoms due to poor antidepressant bioavailability...

AIM: This guideline (GL) is aimed at providing a clinical practice reference for the management of adult patients with overweight or obesity associated with metabolic complications who are resistant to lifestyle modification. METHODS: Surgeons, endocrinologists, gastroenterologists, psychologists, pharmacologists, a general practitioner, a nutritionist, a nurse and a patients' representative acted as multi-disciplinary panel. This GL has been developed following the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach...

BACKGROUND: Leaks following bariatric surgery, while rare, are potentially fatal due to risk of peritonitis and sepsis. Anastomotic leaks and gastro-gastric fistulae following Roux-En-Y gastric bypass (RYGB) as well as staple line leaks after sleeve gastrectomy have historically been treated multimodally with surgical drainage, aggressive antibiotic therapy, and more recently, endoscopically. Endoscopic clipping using over-the-scope clips and endoscopic suturing are two of the most common approaches used to achieve full thickness closure...

Three-dimensional (3D) laparoscopy has several advantages in gastrointestinal surgery. This systematic review determined whether similar benefits exist for bariatric surgical procedures by systematically searching the MEDLINE, Embase, and Scopus databases. Six studies including 629 patients who underwent 2D (386) and 3D (243) laparoscopic bariatric surgeries were selected. Operative time was significantly shorter in patients undergoing 3D laparoscopic gastric bypass (pooled standardized mean difference [SMD] 1...

BACKGROUND: The gastric conduit is the most commonly used replacement organ for reconstruction after minimally invasive McKeown esophagectomy. Although the optimal route of gastric conduit remains controversial, the posterior mediastinal route is physiologically preferable but is not without disadvantages. Here, we report the safety and efficacy of a method of gastric conduit reconstruction via the anterior of the pulmonary hilum route. METHODS: We have used the anterior of the pulmonary hilum route since 2021...

PURPOSE: Sleeve Gastrectomy (SG) is the most performed bariatric surgery, but a considerable number of patients may require revisional procedures for suboptimal clinical response/recurrence of weight (SCR/RoW). Conversion options include One-Anastomosis Gastric Bypass (OAGB) and Single Anastomosis Duodeno-Ileal Bypass (SADI). The study aims to compare SADI vs. OAGB as revisional procedures in terms of early and mid-term complications, operative time, postoperative hospital stay and clinical outcomes...

This case outlines the complications of Roux-en-Y gastric bypass surgery (RYGBS) and demonstrates clinical manifestations of several vitamin deficiencies. We present a 45-year-old female patient who was admitted to our hospital with generalized weakness, anasarca, hypotension, and failure to thrive, a year after she had her RYGBS. After the procedure, she had nausea, vomiting, and diarrhea with progressive inability to tolerate any oral intake. Subsequently, the patient lost over 200 pounds and got bedridden...

OBJECTIVE: We searched for long-term peripheral nerve complications 10-15 years after Roux-en-Y gastric bypass surgery (RYGB), using a comprehensive nerve conduction study (NCS) protocol. METHODS: Patients (n = 175, mean age 52.0, BMI 35.2) and 86 community-controls (mean age 56.8, BMI 27.2) had NCS of one upper and lower limb. New abnormality scores from 27 polyneuropathy-relevant (PNP27s) and four carpal tunnel syndrome-relevant NCS-measures (CTS4s) were compared between groups with non-parametric statistics...

Obesity is associated with several chronic conditions including diabetes, cardiovascular disease, and metabolic dysfunction-associated steatotic liver disease and malignancy. Bariatric surgery, most commonly Roux-en-Y gastric bypass and sleeve gastrectomy, is an effective treatment modality for obesity and can improve associated comorbidities. Over the last 20 years, there has been an increase in the rate of bariatric surgeries associated with the growing obesity epidemic. Sleeve gastrectomy is the most widely performed bariatric surgery currently, and while it serves as a durable option for some patients, it is important to note that several complications, including sleeve leak, stenosis, chronic fistula, gastrointestinal hemorrhage, and gastroesophageal reflux disease, may occur...

Background: Bariatric surgery is an effective treatment for weight loss, but a higher body mass index (BMI) may lead to higher postoperative complication rates. This study aims to compare perioperative and postoperative outcomes between UAE patients with severe obesity (SO) [BMI ≥ 50 kg/m2 ] and non-severe obesity (NSO) [BMI < 50 kg/m2 ] undergoing primary bariatric surgery. Methods : From September 2015 to July 2019, 542 patients, 94 SO (56.5 ± 6.2 kg/m2 ) and 448 NSO (41.8 ± 4.1 kg/m2 ), were retrospectively reviewed...

Metabolic and bariatric surgery (MBS) is the most effective therapeutic intervention for patients with obesity, with sleeve gastrectomy (SG) being the most commonly performed primary MBS procedure. Long-term studies have demonstrated that 15-20% of patients require revisional bariatric surgery (RBS) due to weight-related issues or surgical complications. Despite the gold standard being laparoscopic revision, there are other available approaches such as open or robotic-assisted. An extensive literature review was performed for articles from their inception to February 2024...

PURPOSE: This study presents the short- (less than 6 months) and medium-term (6 months to 2 years) outcomes for weight loss and type 2 diabetes mellitus (T2DM) for all patients undergoing one anastomosis gastric bypass (OAGB) across multiple institutions between 2015 and 2021. MATERIALS AND METHODS: A retrospective analysis of prospectively collected databases was performed including 1022 participants who underwent OAGB at multiple institutions by multiple surgeons between 2015 and 2021...

One of the recent advances in bariatric surgery is the use of magnetic devices. This research paper describes magnetic liver retraction in morbidly obese patients during bariatric surgery. A descriptive, prospective and observational study was carried out, analyzing 100 patients in whom magnetic retraction was used. Mean and SD body mass index was 46.1 ± 5.09 kg/m2 . The magnetic system was successfully used for liver retraction in 95% of cases; in only 5% of cases was its use not possible due to hepatomegaly and severe hepatic steatosis...

PURPOSE: The linear-stapled (LSA) and the circular-stapled anastomosis (CSA) are the two most commonly performed techniques for the gastrojejunostomy (GJ) during laparoscopic Roux-en-Y gastric bypass (RYGB). This study compared the outcome after both techniques with special focus on postoperative morbidity using the comprehensive complication index (CCI). METHODS: Five hundred eighty-eight patients operated between 01/2010 and 12/2019 were included in the final analysis and divided in two cohorts according to the surgical technique of the GJ (LSA (n = 290) or CSA (n = 298))...

The study aimed to evaluate the mid-term weight loss outcomes and complications of revisional one-anastomosis gastric bypass (OAGB) following failed laparoscopic sleeve gastrectomy (LSG). A total of 586 patients underwent LSG from January 2010 to February 2018. Revisional OAGB (rOAGB) was performed in 22 (3.8%) patients. A retrospective analysis of prospectively collected data from 20 patients with at least 12 months of follow-up after the revisional OAGB was carried out. The indications for revisional surgery were as follows: insufficient weight loss-4 (20%), weight regain-13 (65%), weight regain and symptoms of gastroesophageal reflux disease (GERD)-2 (10%), and dysphagia with gastroesophageal reflux-1 (5%)...

BACKGROUND: One anastomosis gastric bypass (OAGB) prevalence is increasing worldwide and shows good mid- to long-term results. Data on long-term outcomes of revisional OAGB (rOAGB) is limited. This study objective is to evaluate the long-term outcomes of patients undergoing primary OAGB (pOAGB) and rOAGB. METHODS: A retrospective analysis of a prospectively maintained patient registry at a single-tertiary center. Patients undergoing OAGB from January 2015 to May 2016 were included and grouped to pOAGB and rOAGB...

BACKGROUND: The extremely obese patient deserves special consideration: significant comorbidities, technical difficulties, and increased postoperative morbidity and mortality are all expected in this patient population. The study compared early postoperative complications (≤30-day) following one-anastomosis gastric bypass (OAGB) morbidity in patients with morbid obesity class IV obesity, body mass index (BMI) ≥50-59.9 kg/m2 , and class V obesity, BMI ≥60 patients...

Obesity is associated with serious comorbidities and economic implications. Bariatric surgery, most commonly Roux-en-Y gastric bypass and sleeve gastrectomy, are effective options for weight loss and the improvement of obesity-related comorbidities. With the growing obesity epidemic, there has been a concomitant rise in bariatric surgeries, particularly in sleeve gastrectomy, which has been the most widely performed bariatric surgery since 2013. Gastroesophageal reflux disease (GERD) is highly prevalent in obese individuals, can significantly impact quality of life and may lead to serious complications...

Roux-en-Y gastric bypass (RYGB) patients are at risk of creating potential spaces for possible internal hernias during the procedure. During pregnancy, the pregnant uterus elevates the bowel, increasing intra-abdominal pressure. Cases reported to date have described mild abdominal pain and no evidence of peritoneal irritation, with inconclusive ultrasound and MRI findings for diagnosis of Petersen's hernia. We present the case of a 42-year-old female patient with a history of RYGB eight years earlier without complications, with a pregnancy of 34 weeks of gestation...
