RESUMO
Introduction: Insulinoma during pregnancy is a rare condition with vague clinical symptoms, making diagnosis challenging. The standard treatment for insulinoma is surgical tumor removal, preferably using a minimally invasive method. However, there have been no recorded examples of employing a robotic platform in pregnant women with insulinoma. In this report, we present the first successful case of robotic enucleation for insulinoma during pregnancy. Case presentation: A 30-year-old pregnant woman presented with recurrent hypoglycemic symptoms throughout her first trimester that were relieved by food intake. After confirming endogenous hyperinsulinemia, an abdominal magnetic resonance imaging scan was performed to locate the tumor. A well-defined 2-cm mass was found in the pancreatic body. Robotic enucleation was performed at week 18 of gestation, and the patient experienced relief from hypoglycemic episodes postoperatively. Her blood glucose levels returned to normal, and she had an uneventful pregnancy. The patient eventually delivered a healthy baby via cesarean section without any complications. Conclusions: For a subset of pregnant individuals with insulinoma, a minimally invasive approach as robotic-assisted surgery is safe and feasible. This innovative technique has the potential to both mothers and fetuses.
RESUMO
Background/Aims: The coronavirus disease 2019 pandemic has affected the worldwide practice of upper gastrointestinal endoscopy. Here we designed a modified N95 respirator with a channel for endoscope insertion and evaluated its efficacy in upper gastrointestinal endoscopy. Methods: Thirty patients scheduled for upper gastrointestinal endoscopy were randomized into the modified N95 (n=15) or control (n=15) group. The mask was placed on the patient after anesthesia administration and particles were counted every minute before (baseline) and during the procedure by a TSI AeroTrak particle counter (9306-04; TSI Inc.) and categorized by size (0.3, 0.5, 1, 3, 5, and 10 µm). Differences in particle counts between time points were recorded. Results: During the procedure, the modified N95 group displayed significantly smaller overall particle sizes than the control group (median [interquartile range], 231 [54-385] vs. 579 [213-1,379]×103/m3; p=0.056). However, the intervention group had a significant decrease in 0.3-µm particles (68 [-25-185] vs. 242 [72-588]×103/m3; p=0.045). No adverse events occurred in either group. The device did not cause any inconvenience to the endoscopists or patients. Conclusions: This modified N95 respirator reduced the number of particles, especially 0.3-µm particles, generated during upper gastrointestinal endoscopy.
RESUMO
PURPOSE: Emerging evidence revealed that brain-derived neurotrophic factor (BDNF), secreted protein acidic and rich in cysteine (SPARC), fibroblast growth factor 21(FGF-21) and growth differentiation factor 15 (GDF-15) are involved in energy metabolism and body weight regulation. Our study aimed at examining their association with BMI, their alterations after anti-obesity treatments, and their association with 1-year weight loss. METHODS: A prospective observational study of 171 participants with overweight and obesity and 46 lean controls was established. All participants received lifestyle educational intervention (LEI) with or without anti-obesity treatments (LEI + bariatric/metabolic surgery, n = 41; LEI + topiramate, n = 46; LEI + liraglutide, n = 31; LEI + orlistat, n = 12; and LEI alone, n = 41). Anthropometric and metabolic parameters, insulin sensitivity, C-reactive protein (CRP), fasting plasma levels of BDNF, SPARC, GDF-15, and FGF-21 were measured at baseline and 1 year. RESULTS: Multiple linear regression showed that fasting levels of SPARC, FGF-21, and GDF-15 were significantly associated with baseline BMI after adjustment for age and sex. At 1 year, the average weight loss was 4.8% in the entire cohort with a significant improvement in glycemia, insulin sensitivity, and CRP. Multiple linear regression adjusted for age, sex, baseline BMI, type of treatment, and presence of T2DM revealed that the decrease in log10FGF-21 and log10GDF-15 at 1 year from baseline was significantly associated with a greater percentage of weight loss at 1 year. CONCLUSIONS: This study highlights the association of SPARC, FGF-21, and GDF-15 levels with BMI. Decreased circulating levels of GDF-15 and FGF-21 were associated with greater weight loss at 1 year, regardless of the types of anti-obesity modalities.

Background and aim: Endoscopic sleeve gastroplasty (ESG) is an effective treatment for obesity. Recently, a novel single-channel endoscopic suturing device has been made available to overcome the need for a double-channel endoscope. However, there is limited evidence evaluating its utility for ESG. In this multicenter study, we aim to assess the efficacy and safety of the single-channel suturing device for ESG. Methods: We reviewed the records of 18 patients who underwent ESG using the novel device at the Singapore General Hospital, Singapore, and Siriraj Hospital, Bangkok, between 2020-2021. We adopted a "U" suture pattern. Our primary outcome was to assess technical feasibility and safety. The secondary outcome was to determine the percentage of total body weight loss at 1 year. Results: The mean ± SD age and body mass index were 42 ± 8.5 years and 34.9 ± 4.4 kg/m2, respectively. The majority were female (61%). ESG was technically successful in 94% (n = 17) of patients. Device dislodgement occurred in one patient. We used an average of five sutures (range, 4-8), and the mean ± SD procedure time was 96.5 ± 43.8 min. No complications occurred. The mean ± SD length of stay was 2.3 ± 1.5 days. The mean ± SD percentage of total body weight loss at 6 and 12 months were 16 ± 5.2% and 13.1 ± 5.8%, respectively. We found that >5%, >10%, and >15% total body weight loss was observed in 83.3%, 72.2%, and 56%, respectively. Conclusion: ESG using the single-channel endoscopic suturing system is safe and effective for inducing weight loss at 1 year in patients with obesity.
RESUMO
BACKGROUND: Despite the infrequency of trocar site hernias (TSHs), fascial closure continues to be recommended for their prevention when using a ≥ 10-mm trocar. AIM: To identify the necessity of fascial closure for a 12-mm nonbladed trocar incision in minimally invasive colorectal surgeries. METHODS: Between July 2010 and December 2018, all patients who underwent minimally invasive colorectal surgery at the Minimally Invasive Surgery Unit of Siriraj Hospital were retrospectively reviewed. All patients underwent cross-sectional imaging for TSH assessment. Clinicopathological characteristics were recorded. Incidence rates of TSH and postoperative results were analyzed. RESULTS: Of the 254 patients included, 70 (111 ports) were in the fascial closure (closed) group and 184 (279 ports) were in the nonfascial closure (open) group. The median follow up duration was 43 mo. During follow up, three patients in the open group developed TSHs, whereas none in the closed group developed the condition (1.1% vs 0%, P = 0.561). All TSHs occurred in the right lower abdomen. Patients whose drains were placed through the same incision had higher rates of TSHs compared with those without the drain. The open group had a significantly shorter operative time and lower blood loss than the closed group. CONCLUSION: Routine performance of fascial closure when using a 12-mm nonbladed trocar may not be needed. However, further prospective studies with cross-sectional imaging follow-up and larger sample size are needed to confirm this finding.
RESUMO
In the highly contagious coronavirus disease 2019 pandemic, aerosol-generating procedures (AGPs) are associated with high-risk of transmission. Upper gastrointestinal endoscopy is a procedure with the potential to cause dissemination of bodily fluids. At present, there is no consensus that endoscopy is defined as an AGP. This review discusses the current evidence on this topic with additional management. Prevailing publications on coronavirus related to upper gastrointestinal endoscopy and aerosolization from the PubMed and Scopus databases were searched and reviewed. Comparative quantitative analyses showed a significant elevation of particle numbers, implying that aerosols were generated by upper gastrointestinal endoscopy. The associated source events have also been reported. To reduce the dispersion, certain protective measures have been developed. Endoscopic unit protocols are recommended for the concerned personnel. Therefore, upper gastrointestinal endoscopy should be classified as an AGP. Proper practices should be adopted by healthcare workers and patients.
RESUMO
BACKGROUND: The SARS-CoV2 virus has been identified in abdominal cavity of the COVID-19 patients. Therefore, the potential viral transmission from any surgical created smoke in these patients is of concern especially in laparoscopic surgery. This study aimed to compare the amount of surgical smoke and surgical field contamination between laparoscopic and open surgery in fresh cadavers. METHODS: Cholecystectomy in 12 cadavers was performed and they were divided into 4 groups: laparoscopic approach with or without smoke evacuator, and open approach with or without smoke evacuator. The increased particle counts in surgical smoke of each group were analyzed. In the model of appendectomy, surgical field contamination under ultraviolet light and visual contamination scale between laparoscopic and open approach were compared. RESULTS: Open cholecystectomy significantly produced a greater amount of overall particle sizes, particle sizes < 5 µm and particle sizes ≥ 5 µm than laparoscopic cholecystectomy (10,307 × 103 vs 3738 × 103, 10,226 × 103 vs 3685 × 103 and 81 × 103 vs 53 × 103 count/m3, respectively at p < 0.05). The use of smoke evacuator led to decrease in the amount of overall particle sizes of 58% and 32.4% in the open and laparoscopic chelecystectomy respectively. Median (interquatile range) visual contamination scale of surgical field in open appendectomy [3.50 (2.33, 4.67)] was significantly greater than laparoscopic appendectomy [1.50 (0.67, 2.33)] at p < 0.001. CONCLUSIONS: Laparoscopic cholecystectomy yielded less smoke-related particles than open cholecystectomy. The use of smoke evacuator, abeit non-significantly, reduced the particles in both open and laparoscopic cholecystectomy. Laparoscopic appendectomy had a lower degree of surgical field contamination than the open approach.

BACKGROUND AND OBJECTIVES: Laparoscopic cholecystectomy with common bile duct exploration (LC with LCBDE) remains the preferred technique for difficult common bile duct stone (CBDS) removal. The chopstick method uses commonly available instruments and may be cost-saving compared to other techniques. We studied the outcome of LCBDE using the chopstick technique to determine if it could be considered a first-choice method. METHODS: Data from all patients that underwent LCBDE from January 1, 2012 to April 30, 2019 were retrospectively analyzed. A standard 4-port incision and CBDS permitted extraction with two laparoscopic instruments by chopstick technique via vertical choledochotomy. Demographic data, stone clearance rate, surgical outcomes, complications, and other associated factors were evaluated. RESULTS: Thirty-two patients underwent LCBDE. The mean number of preoperative endoscopic retrograde cholangiopancreatography (ERCP) sessions was 2.4. In 65.5% of cases, the CBDS was completely removed by the chopstick technique, while 96.9% of stones were removed after using additional tools. The need for additional instruments was associated with increased age, increased numbers of stones, longer period from the latest ERCP session, and previous upper abdominal surgery. The conversion rate to open surgery was 28.1% and was significantly associated with a history of upper abdominal surgery. CONCLUSION: The chopstick technique is a good alternative and could be considered as a first-line technique in LCBDE to remove the CBDS in cases with 1 to 2 large suprapancreatic CBDS due to instrument availability, cost-effectiveness, and comparable surgical outcomes.

INTRODUCTION: Inguinal hernia is one of the most surgical common diseases. Giant inguinal hernia is more unusual and significantly challenging in terms of surgical management. It is defined as an inguinal hernia that extends below the midpoint of inner thigh when the patient is in standing position. PRESENTATION OF CASE: A 67-year-old male presented with giant right-side inguinal hernia with symptoms of partial colonic obstruction and significant weight loss. Barium enema revealed ascending colon, cecum and ileum contained in hernia sac without significant lesions of large bowel. He underwent hernia repair with omentectomy. Hernioplasty with polypropylene mesh was performed without any complications. He recovered uneventfully. DISCUSSION: There were several repair techniques suggested by published articles such as resection of the content and increased intraabdominal volume procedure. Many key factors for management of the giant inquinal hernia were discussed. A new classification of the giant inquinal hernia was described. CONCLUSION: Surgical repair for the giant inquinal hernia is challenging and correlated with significant morbidity and mortality due to increased intra-abdominal pressure.
RESUMO
INTRODUCTION: Acquired post-traumatic tracheoesophageal fistula (TEF) is an uncommon entity requiring early diagnosis. Among the many strategies in surgical management, we report a case successfully treated with a single-stage tracheal resection and esophageal repair with platysma myocutaneous interposition flap. PRESENTATION OF CASE: A 24-year-old man had a motor vehicle accident with head injury and cerebral contusion who required mechanical ventilation support. Three weeks later, he developed hypersecretion, and recurrent episodes of aspiration pneumonia. The chest computed tomography, esophagogastroduodenoscopy, and bronchoscopy revealed a large TEF diameter of 3cm at 4.5cm from carina. Single-stage tracheal resection with primary end-to-end anastomosis and esophageal repair with platysma myocutaneous interposition flap was performed. A contrast esophagography was done on post-operative day 7 and revealed no leakage. He was discharged on post-operative day 10. Esophagogastroduodenoscopy at 1 month revealed patient esophageal lumen. At present he is doing well without any evidence of complications such as esophageal stricture or fistula. DISCUSSION: There are many choices of myocutaneous muscle flaps in trachea and esophageal closure or reinforcement. The platysma myocutaneous flap interposition is simple with the advantage of reduced bulkiness. Concern on the vascular supply is that flap should be elevated with the deep adipofascial tissue under the platysma to ensure that the flap survival is not threatened. CONCLUSION: The treatment of acquired TEF with platysma myocutaneous flap is an alternative procedure for a large uncomplicated TEF as it is effective, technically ease, minimal donor site defect and yields good surgical results.
