RESUMEN
INTRODUCTION: Weight regain and insufficient weight loss are major challenges after metabolic bariatric surgery (MBS), affecting patients' comorbidities and quality of life. The current systematic review and meta-analysis aim to assess the efficacy and safety of GLP-1 receptor agonists (GLP-1 RA) in patients with weight regain or insufficient weight loss after MBS. METHODS: A systematic search was conducted across PubMed, Embase, Scopus, and Web of Science databases to find the relevant studies. RESULTS: A total of 19 articles were included. The highest doses of liraglutide and semaglutide were 3 mg per day and 1 mg once weekly, respectively, in the included studies. The mean differences in weight and body mass index after treatment were -7.02 kg or 3.07 kg/m2, -8.65 or -5.22 kg/m2, and -6.99 kg or -3.09 kg/m2 for treatment durations of ≤ 6 months, 6-12 months, and >12 months with liraglutide, respectively. Additionally, weekly semaglutide showed significantly greater weight loss compared to daily liraglutide, with a mean difference of 4.15 kg. Common complications included nausea (19.1%), constipation (8.6%), abdominal pain (3.7%), and vomiting (2.4%). CONCLUSION: Using GLP-1 RA is a safe and effective treatment for weight regain and insufficient weight loss after MBS.
RESUMEN
INTRODUCTION: The role of routine preoperative esophagogastroduodenoscopy (EGD) in bariatric surgery candidates is controversial. This study compares preoperative EGD outcomes with patient-reported gastroesophageal reflux disease (GERD) symptoms to determine if a case-based EGD is appropriate. PATIENTS AND METHODS: A prospective cohort study was conducted from April 2022 through September 2023 in Mashhad, Iran. All patients underwent EGD. To assess GERD symptoms, we used the GERD-Health Related Quality of Life questionnaire. Patients were categorized into two groups: the asymptomatic group (GERD-HRQL = 0) and the symptomatic group (GERD-HRQL > 0). RESULTS: A total of 165 patients were included, out of which 133 (80.6%) were in the symptomatic group and 32 (19.4%) were in the asymptomatic group. Esophagitis was present in 41 (24.8%) patients. There was no significant difference in the frequency of esophagitis (18.8% vs. 26.3%, p-value = 0.37), hiatal hernia (18.8% vs. 18.8%, p-value = 1.00), gastritis (56.3% vs. 63.9%, p-value = 0.42), and H. pylori infection (9.4% vs. 12.0%, p-value = 1.00) between the asymptomatic and symptomatic groups, respectively. None of the demographic factors or comorbidities of asymptomatic patients were associated with esophagitis, except for hiatal hernia (OR = 7.67, 95% CI 3.01-19.53, p-value < 0.001). Receiver operating characteristic (ROC) analysis showed that the GERD-HRQL total scores, as well as the heartburn and regurgitation subscales, were poor predictors of esophagitis (AUC 0.57, 0.51, and 0.56, respectively). CONCLUSION: EGD findings were not associated with GERD symptoms in candidates for bariatric surgery.

Introduction and importance: Paraduodenal hernias (PDHs) are congenital internal hernias. Overall, internal hernias are between 0.2 % and 0.9 %, while 53 % of these statistics are for PDH. There are left and right types of PDHs. CASE PRESENTATION: An otherwise healthy 26-year-old man was presented with a sudden-onset epigastric and right upper quadrant abdominal pain. Abdominopelvic double contrasted CT scan revealed multiple dilated proximal-mid small bowel loops in the portal venous phase consistent with small bowel obstruction, suggesting concomitant bowel malrotation with internal paraduodenal hernia. The patient with the pre-operative diagnosis of small bowel obstruction due to volvulus was scheduled for emergency surgery. He was four weeks complication-free in his regular follow-up. CLINICAL DISCUSSION: In 1857, Treitz first described PDH as a phenomenon when the primitive midgut in embryonic life abnormally rotates and causes mesocolic hernia. The location of the duodenal recess is the origin point for describing the hernia; thus, the jejunum is the most common herniating viscus. However, the stomach, small intestine, and sometimes the colon usually consist of the contents of the hernia. CONCLUSION: In the absence of surgical history, abdominal wall hernia, and intra-abdominal inflammatory disease, in case of repeated abdominal pain or intestinal obstruction, and if no other causes are found, the possibility of a PDH should be kept in mind.
RESUMEN
Malignant melanoma of the small intestine is mostly a metastatic tumor of other primary lesions, especially of skin origin. Primary malignant melanoma of the small intestine is very uncommon. The clinical presentation is usually nonspecific, thus leading to late diagnosis. We report a 42-year-old man who presented to the emergency department of Imam-Reza Hospital with symptoms and signs of peritonitis and was a candidate for emergency laparotomy and enterectomy. The medical and family history were unremarkable. A bulky mass was seen 190 cm away from the Treitz band, and a diagnosis of malignant melanoma was confirmed by histologic and immunohistochemical study. Further clinical examination revealed no primary tumor elsewhere, so the diagnosis of primary small intestinal melanoma was concluded. Although metastatic malignant melanoma in the GI tract is common, the primary one is a very rare entity. The diagnosis could be challenging because a thorough investigation is needed to rule out the possible initial origin.
RESUMEN
Key Clinical Message: Although gastro-pleural fistulas after bariatric surgeries are rare, they are life-threatening complications that should be suspected in patients who present with gastrointestinal or respiratory symptoms after bariatric surgery. Abstract: Previous studies showed an incidence rate of 0.2%-0.37% for gastro-pleural fistulas after bariatric surgery. We report a 56-year-old female with a rare presentation of gastro-pleural fistula after Roux-en-Y gastric bypass, simultaneous fistula of the gastric pouch, and remnant to the pleural space.
RESUMEN
This systematic review of 10 studies aimed to investigate the mid- and long-term results of duodeno-ileostomy with sleeve gastrectomy (SADI-S) according to the PRISMA guideline. Related articles, which reported outcomes of laparoscopic SADI-S with follow-up ≥ 3 years, were selected and analyzed. The percentage of excess weight loss (EWL) was 70.9-88.7%, and 80.4% at 6, and 10 years, respectively. The more common late complications were malabsorption (6.3%) and gastroesophageal reflux disease (GERD) (3.6%). The remission rates of hypertension, diabetes, GERD, obstructive sleep apnea, and dyslipidemia were 62.9%, 81.3%, 53.2%, 60.9%, and 69.7%, respectively. In conclusion, SADI-S is a safe and effective surgical technique with durable weight loss and a high rate of comorbidity resolution in mid and long term.

This systematic review and meta-analysis aimed to investigate the incidence of new-onset gastroesophageal reflux, reflux change, esophagitis, Barrett's esophagus, and revision due to reflux, gastritis, and marginal ulcer after one-anastomosis gastric bypass (OAGB). We performed subgroup analyses based on primary and revisional OAGB and time of follow-up. Meta-analysis of 87 studies with 27,775 patients showed a 6% rate of new-onset reflux after OAGB. Preoperative reflux status did not change significantly after OAGB. The rate of esophagitis and Barrett's esophagus was 15% and 1%, respectively. The new-onset reflux rate after OAGB was significantly higher than gastric bypass but not different with sleeve gastrectomy. The current study showed a relatively low rate of reflux and its complications after OAGB, but it was significantly higher than Roux-en-Y gastric bypass.

Obesity is considered one of the independent risk factors for atherosclerosis and is strongly correlated with cardiovascular morbidity and mortality. Previous studies showed carotid intima-media thickness (CIMT), flow-mediated dilation (FMD), and nitrite-mediated dilatation (NMD) are reliable non-invasive markers of arterial damage and dysfunction. The aim of this study was to evaluate the effect of bariatric surgery on CIMT, FMD, and NMD markers in patients with obesity. A systematic search was performed in the PubMed, Embase, Scopus, and Web of Science databases until May 2022. All the English-published studies on the effect of bariatric surgery on CIMT, FMD, and NMD were included. A quantitative meta-analysis was performed, as well as subgroup analyses for the type of procedure and duration of follow-up. Meta-analysis of 41 studies with 1639 patients showed CIMT was significantly reduced by .11 mm after bariatric surgery (95% CI, -.14 to -.08; P < .001; mean follow-up = 10.8 mo). The pooled analysis of 23 studies with 1106 patients showed an increase of FMD by 4.57% after bariatric surgery (95% CI, 2.69-6.44; P < .001; mean follow-up = 11.5 mo). The results of a pooled analysis of 12 studies with 346 patients showed a significant increase of NMD by 2.46% after bariatric surgery (95% CI, .99-3.94; P < .001; mean follow-up = 11.4 mo). The random effect meta-regression demonstrated that baseline CIMT and FMD significantly affect the changes in CIMT and FMD. This meta-analysis showed bariatric surgery can improve CIMT, FMD, and NMD markers in patients with obesity. These improvements show the known effect of metabolic surgery in decreasing cardiovascular risk.

Supralevator fistula stays a challenge in general surgery. We present a case with supralevator anorectal fistula and subsequent retroperitoneal necrotizing fasciitis in which autologous platelet-rich plasma and platelet-rich fibrin glue were used for fistula closure. A 59-year-old man was admitted with pelvic pain and fever. Abdominopelvic sonography and CT scan reported a deep horseshoe-shaped anorectal abscess with extension to the pelvic floor, supralevator, psoas, retroperitoneal muscles, and kidneys. He was managed with antibiotics, abscess drainage, repeated radical surgical debridement, and necrosectomy. After 30 days, he was discharged, but he returned to the office with the complaint of purulent discharge from the hypogastric region and a diagnosis of fistula formation. Platelet-rich plasma was injected around the fistula into the tissue, and platelet-rich fibrin glue was introduced to the fistula tract. At the 11-month follow-up, the patient did not have voiding dysfunction, constipation, diarrhea, or fistula tract infection. Autologous platelet-rich plasma injection and platelet-rich fibrin glue insertion suggest a secure and effective approach for treating supralevator anorectal fistula.

The purpose of this study was to provide pooled data from all studies on the impact of bariatric surgery on cardiac structure, and systolic and diastolic function evaluated by either echocardiography or cardiac magnetic resonance. PubMed, Web of Science, Embase, and Scopus databases were searched. Almost all of cardiac left-side structural indices improved significantly after bariatric surgery. However, right-side structural indices did not change significantly. Left ventricular ejection fraction and most of the diastolic function indices improved significantly after the bariatric surgery. The subgroup analysis showed that the left ventricular mass index decreased more in long-term follow-up (≥ 12 months). In addition, subgroup analysis of studies based on surgery type did not reveal any difference in outcomes between gastric bypass and sleeve gastrectomy groups.

Novel coronavirus disease 2019 (COVID-19) as a potential health risk factor continues to spread worldwide. Although common symptoms include headache and respiratory symptoms, some studies have suggested that COVID-19 may cause coagulation disorders and thrombolytic events, disrupt blood flow to the visceral organs, and cause some complications such as mesenteric ischemia. The authors reported four cases of acute mesenteric ischemia associated with COVID-19 confirmed in patients hospitalized in Imam Reza Hospital (a COVID-19 referral center in Mashhad University of Medical Sciences, Mashhad, Iran). The authors described the pathological findings that may be associated with this infection. The authors collected clinical data, imaging, microscopic, and operative findings of four patients with severe COVID-19 infection and evidence of intestinal necrosis. These four cases of severe COVID-19 pneumonia simultaneously showed intestinal necrosis during the infection process, indicating a relationship between coronavirus and mesenteric vascular events. Physicians should be aware of thrombosis symptoms in the digestive system in patients with severe COVID-19.
RESUMEN
BACKGROUND: Shoulder pain is among the early postlaparoscopic symptoms related to carbon dioxide used for pneumoperitoneum, which remains in the abdominal cavity. Therefore, incentive spirometry (IS) is a novel technique to alleviate this pain following laparoscopic cholecystectomy (LC). The present study was designed to investigate if the use of IS after LC would relieve shoulder tip pain, and determine the amount of postoperative opioid analgesics utilized. MATERIALS AND METHODS: This randomized clinical trial was conducted on patients who were clinically diagnosed with cholecystitis, and underwent LC. Accordingly, group I patients (n=42) received IS (including 10 deep breaths with a spirometer in sitting or semisitting positions) in full consciousness every 2 hours starting at 2 hours after surgery, but group II patients (n=42) did not have respiratory physiotherapy. The postoperative shoulder pain after the surgery was further evaluated by a numerical rating scale (NRS). RESULTS: At 4, 8, 12, 24, and 48 hours following LC, the NRS pain scores significantly reduced in group I compared with group II. In addition, the results of the repeated measures analysis of variance indicated significantly lower NRS pain scores within the first 48 hours after LC in group I compared with group II. Consequently, the study findings showed a significantly higher percentage of cases in group II, requiring postoperative analgesics, in comparison with group I. CONCLUSIONS: IS decreased the severity of shoulder tip pain after LC with no complications. Thus, IS may be considered as a viable alternative to other laparoscopic interventions. However, still further studies are necessary to evaluate its efficacy compared with other techniques.

Introduction. Solid pseudopapillary neoplasm (SPN) is a rare and indolent pancreatic tumor with low malignant potential which frequently occurs in reproductive-age females. Complete resection is almost always the curative option. Case Presentation. We present a 20-year-old woman with acute epigastric pain and vomiting in multiple episodes. Abdominal ultrasound showed a hypoechoic lesion with the probable source in the pancreas. Following that, CT scans and Endoscopic Ultrasound (EUS) manifested a 9 × 7.5 cm-sized hypodense mass with heterogeneous well-defined margins in the pancreas suggesting the diagnosis of SPN. Whipple's procedure was performed. Histopathological examination and immunohistochemistry confirmed SPN without evidence of malignancy. Discussion. SPN is known as a tumor with a favorable prognosis and a long survival rate after complete resection. However, some literature focused on minimally invasive surgery as an alternative surgical approach.
RESUMEN
BACKGROUND: Selection of anesthetic approach for lower extremity operations is often a controversial issue for anesthesiologists. OBJECTIVES: The aim of this study was to compare the incidence and severity of back pain between general and spinal anesthesia, and to find effective factors in developing postoperative back pain. PATIENTS AND METHODS: In a randomized clinical trail, 148 patients with elective lower extremity surgeries were randomly allocated into two groups of 74. The first group received general anesthesia and the second group underwent spinal anesthesia. The incidence of back pain was observed and documented. The severity of back pain was assessed at the first, fourth and eighth postoperative weeks by visual analogue scale. RESULTS: The mean of patients' age was 35.50 ± 13.34 years. The incidence and mean of back pain severity among all participants were respectively 35.80% and 15.95% at the first week, 7.40% and 2.43% at the fourth week, and 1.4% and 0.27% at the eighth postoperative week. The incidence and mean of back pain severity in spinal group were respectively 39.2% and 18.11% at the first, 12.2% and 3.92% at the fourth, and 2.7% and 0.54% eighth postoperative weeks. In general anesthesia group, these figures were respectively 32.4% and 13.78% at the first week and 2.7% and 0.95% at the fourth postoperative week. No back pain was reported at the eighth postoperative week. The incidence and severity of back pain in the first week showed significant difference between the two groups, while the mean severity of back pain showed significant difference at the fourth week after operation. CONCLUSIONS: Spinal anesthesia could be probably considered as the sole effective factor in the development of back pain after operation.
