    Sleeve gastrectomy has gained popularity over the years and is commonly performed laparoscopically through multiple small incisions. The arrival of single incision laparoscopic surgery has been a game changer, allowing for sleeve gastrectomy to be performed through a cosmetically more appeasing scar with improved patient
    satisfaction. In this article, we describe the history, technical challenges, proposed solutions to some of the hurdles faced during single-incision laparoscopic bariatric surgery and highlight our method of performing single incision laparoscopic sleeve gastrectomy purely through a single access device.

    Recent studies have demonstrated the effectiveness of switching bipolar radiofrequency ablation (bRFA) in treating liver cancer. Nevertheless, the clinical use of the treatment remains less common than conventional monopolar RFA - likely due to the lack of understanding of how the tissues respond thermally to the switching effect. The problem is exacerbated by the numerous possible switching combinations when bRFA is performed using bipolar needles, thus making theoretical deduction and experimental studies difficult. This article addresses this issue via computational modelling by examining if significant variation in the treatment outcome exists amongst six different electrode configurations defined by the X-, C-, U-, N-, Z- and O-models. Results indicated that the tissue thermal and thermal damage responses varied depending on the electrode configuration and the operating conditions (input voltage and ablation duration). For a spherical tumour, 30 mm in diameter, complete ablation could not be attained in all configurations with 70 V input voltage and 5 minutes ablation duration. Increasing the input voltage to 90 V enlarged the coagulation zone in the X-model only. With the other configurations, extending the ablation duration to 10 minutes was found to be the better at enlarging the coagulation zone.

    No-touch bipolar radiofrequency ablation (bRFA) is known to produce incomplete tumour ablation with a 'butterfly-shaped' coagulation zone when the interelectrode distance exceeds a certain threshold. Although non-confluent coagulation zone can be avoided by not implementing the no-touch mode, doing so exposes the patient to the risk of tumour track seeding. The present study investigates if prior infusion of saline into the tissue can overcome the issues of non-confluent or butterfly-shaped coagulation. A computational modelling approach based on the finite element method was carried out. A two-compartment model comprising the tumour that is surrounded by healthy liver tissue was developed. Three cases were considered; i) saline infusion into the tumour centre; ii) one-sided saline infusion outside the tumour; and iii) two-sided saline infusion outside the tumour. For each case, three different saline volumes were considered, i.e. 6, 14 and 22 ml. Saline concentration was set to 15% w/v. Numerical results showed that saline infusion into the tumour centre can overcome the butterfly-shaped coagulation only if the infusion volume is sufficient. On the other hand, one-sided infusion outside the tumour did not overcome this. Two-sided infusion outside the tumour produced confluent coagulation zone with the largest volume. Results obtained from the present study suggest that saline infusion, when carried out correctly, can be used to effectively eradicate liver cancer. This presents a practical solution to address non-confluent coagulation zone typical of that during two-probe bRFA treatment.

    BACKGROUND: Weight loss surgery is an established intervention for obesity and related conditions, ensuring sustained weight reduction and improved comorbidities. Post-bariatric surgery, maintaining nutritional adequacy and weight loss necessitates ongoing, intensive dietary support. This research aims to discern the impact of standard care vs. intensive dietary support on outcomes following bariatric surgery within an Asian demographic. This study aims to research the part that intensive dietary support plays in contrast to standard care in altering weight loss and BMI change following bariatric surgery.

    METHODS: A retrospective analysis of medical records from a Malaysian tertiary care hospital documented bariatric surgeries conducted from January 2020 to January 2022. Rigorous criteria selected 200 patients from 327, evenly split between standard care and intensive dietary support groups. The latter underwent six mandatory visits with a surgeon and a dietitian in the initial 3 months post-surgery. A dual-review mechanism was implemented for data interpretation, increasing robustness, and reducing biases in our findings.

    RESULTS: At 6 and 12 months, the intensive dietary support group exhibited significantly greater weight loss and BMI reduction (p < 0.01). Postoperative complications did not significantly differ between groups.

    CONCLUSION: In an Asian population, intensive dietary support enhances weight loss and BMI reduction compared to standard care after bariatric surgery.

    Juvenile nasopharyngeal angiofibroma (JNA) is a rare benign neoplasm that occurs almost exclusively in the nasopharynx of adolescent males. Surgery remains the primary treatment of choice. JNA has always presented a management challenge to surgeons because of its vascular nature, site of occurrence, and local tissue destruction. The surgical approaches are either standard open method which include external or intraoral incisions, or the recent advanced approach, i.e. via using the endonasal endoscope. It is widely accepted that the use of preoperative angiographic embolization reduces the occurrence of intraoperative bleeding and facilitates tumour removal. However, angiographic embolization is not available at all centres. The purpose of this article is to present our experience with five patients diagnosed with JNA who were resected without embolization, using various surgical approaches. Two tumours were removed via endonasal endoscopic surgery. None of the tumours were embolized prior to surgery. We highlight the preoperative evaluation of tumour extent, using both computed tomography (CT) and magnetic resonance angiography, and the importance of temporary clamping of the external carotid artery intraoperatively. Our results suggest that the latter procedure is a safe and effective means of facilitating surgery and reducing intraoperative bleeding.

    Craniosynostosis is a premature pathologic fusion of one or more cranial vault sutures leading to abnormally-shaped skull. It can occur in isolated event (non-syndromic), or it can occur in conjunction with other anomalies in welldefined patterns (syndromic). The diagnosis rests on clinical examination and confirmation is generally on the computed tomography scan. The need for surgery is both for cosmetic and functional reasons. Here we describe a case of nonsyndromic craniosynostosis that was treated with frontal orbital advancement (FOA). The potential benefits of FOA need to be carefully weighed against the potential complications when deciding for any surgical intervention.

    ABSTRACT: The aim of this study was to evaluate the effects of multiple factors (congenital and postnatal treatment factors) on the treatment outcome by assessing the maxillary arch dimension of children with unilateral cleft lip and palate (UCLP). Eighty-five Pakistani children with UCLP were taken who received cheiloplasty and palatoplasty. Laser scanned 3D digital models of UCLP subjects were prepared before any orthodontic treatment and bone grafting at 7.69 ± 2.46 (mean ± standard deviation) years of age. Inter-canine width (ICW), inter-molar width (IMW), and arch depth (AD) measurements of maxillary arch were measured with Mimics software. Multiple linear regression analyses were used to evaluate the association between congenital factors (age, gender, UCLP side, family history of cleft) and postnatal treatment factors (techniques of cheiloplasty and techniques of palatoplasty) with maxillary arch dimensions (ICW, IMW, and AD). P value was set at 5%. The mean (standard deviation) dimensions of ICW, IMW, and AD are 26.7 (5.70) mm, 43.3 (4.66) mm, and 27.1 (5.26) mm, respectively. There is no significant association found between multiple factors and maxillary arch dimensions. This regression analysis shows no significant association between multiple factors and MAD in this sample.

    PURPOSE: For the liver to remain viable, the resection during hepatectomy procedure should proceed along the major vessels; hence, the resection planes of the anatomic segments are defined, which mark the peripheries of the self-contained segments inside the liver. Liver anatomic segments identification represents an essential step in the preoperative planning for liver surgical resection treatment.

    METHOD: The method based on constructing atlases for the portal and the hepatic veins bifurcations, the atlas is used to localize the corresponding vein in each segmented vasculature using atlas matching. Point-based registration is used to deform the mesh of atlas to the vein branch. Three-dimensional distance map of the hepatic veins is constructed; the fast marching scheme is applied to extract the centerlines. The centerlines of the labeled major veins are extracted by defining the starting and the ending points of each labeled vein. Centerline is extracted by finding the shortest path between the two points. The extracted centerline is used to define the trajectories to plot the required planes between the anatomical segments.

    RESULTS: The proposed approach is validated on the IRCAD database. Using visual inspection, the method succeeded to extract the major veins centerlines. Based on that, the anatomic segments are defined according to Couinaud segmental anatomy.

    CONCLUSION: Automatic liver segmental anatomy identification assists the surgeons for liver analysis in a robust and reproducible way. The anatomic segments with other liver structures construct a 3D visualization tool that is used by the surgeons to study clearly the liver anatomy and the extension of the cancer inside the liver.

    The use of buccal fat pad in the management of osteoradionecrosis has not been described previously. A series of 10 consecutive cases of osteoradionecrosis treated with a combination of sequestrectomy and buccal fat pad is presented. The data were obtained by reviewing operative and medical records. The combination of sequestrectomy and buccal fat pad flap was successful in 86% of cases of stage II osteoradionecrosis and in 0% of cases of stage III. The overall success rate was 60%. Based on the result of this series, this treatment regime appeared to be beneficial in stage II osteoradionecrosis.
