Introduction: Variations in biliary ductal and hepatic vascular anatomy increase the complexity of surgery for choledochal cysts (CDC). The laparoscopic approach for the management of paediatric CDCs with variant anatomy is underreported. This study aimed to describe anatomical variations, operative techniques and early outcomes of laparoscopic hepaticojejunostomy (HJ) in children with CDCs and variant anatomy.

Patients and methods: We conducted a retrospective review of 40 children who underwent laparoscopic CDC excision with HJ between 2019 and 2024 in a single surgical unit. Patients were divided into Group I (with anatomical variations, n = 20) and Group II (without variations, n = 20). Data on demographic details, clinical presentation, imaging findings, pre-operative interventions, ductal and vascular anatomical variations, surgical techniques, intraoperative variables, post-operative complications and outcomes were collected and analysed.

Results: Ductal variations were found in 10 patients, with aberrant right posterior sectoral duct being the most common. Vascular variations were identified in 12 patients, with anteriorly crossing the right hepatic artery (RHA) being the most frequent. Group I had a higher mean age (7.32 vs. 3.57 years, P = 0.014) and longer operative times (415 vs. 364 min, P < 0.0001). Conversion to laparotomy was necessary in 10% of Group I and 15% of Group II patients ( P = 0.634). Post-operative complications, primarily minor (Clavien-Dindo Grade I or II), occurred in 40% of Group I and 30% of Group II ( P = 0.495). Group I had a significantly shorter time to full feeds (72 vs. 80 h, P = 0.015). Both groups had similar post-operative hospital stays and follow-up durations. At the last follow-up, all patients, except one with liver failure in Group II, were asymptomatic with no significant biliary dilatation or liver function abnormalities.

Conclusion: Laparoscopic management of CDCs with variant ductal and vascular anatomy in children is feasible, safe and effective. Detailed pre-operative imaging, meticulous intraoperative assessment and tailored surgical techniques are crucial for successful outcomes.

Abstract: The available options for recurrent incisional hernias (RIH) following previous laparoscopic intraperitoneal onlay mesh (IPOM) plus were open onlay repair, open Rives-Stoppa (RS), laparoscopic enhanced view totally extraperitoneal-RS (ETEP-RS) and laparoscopic subcutaneous onlay mesh repair. Majority of these RIH were managed by open onlay mesh repairs or laparoscopic Redo IPOM plus. There are not much data available in the literature on the ETEP approach for RIH following previous IPOM plus with the placement of mesh in the retrorectus space. In this article, I would like to share technical aspects, challenges faced and tips to overcome these challenges of performing ETEP for RIH following previous IPOM plus repairs.

Abstract: This report describes the rare case of transverse testicular ectopia (TTE) associated with polyorchidism in a 16-month-old male, successfully managed through laparoscopic surgery. The patient presented with bilateral cryptorchidism, a palpable mass in the right inguinal canal and an absent left-side gonad. Ultrasound revealed three gonad-like structures. Laparoscopy identified duplicated and fused testes at the right deep inguinal ring, and a third testis in the right inguinal canal. Minimally invasive techniques positioned the duplicated testes in the right hemiscrotum and the single testis in the left hemiscrotum. Post-operative follow-up confirmed optimal scrotal positioning, with normal growth. This rare case underscores the efficacy of laparoscopy in diagnosing and managing rare paediatric conditions, providing valuable insights for surgeons facing cryptorchidism or scrotal masses.

Introduction: The impact of laparoscopic surgery on homeostatic systems necessitates careful consideration of intra-abdominal pressure (IAP) management. This study investigated the effects of low-pressure pneumoperitoneum with deep neuromuscular blockade (NMB) on surgeon satisfaction, haemodynamics and post-operative outcomes in laparoscopic cholecystectomy patients.

Patients and methods: The study design involves prospective randomised control. Ninety patients were assigned to low (7-10 mmHg, n = 45) or normal (12-16 mmHg, n = 45) IAP groups. Deep NMB, guided by train-of-four monitoring, was administered. This study evaluated surgical rating scale scores, haemodynamics and post-operative outcomes through a literature review. A computer programme (IBM, SPSS) was used for statistical analysis. Chi-square and Mann-Whitney U tests were used to analyse patients' IAP levels, additional NMB requirements, surgical rating scale scores and numerical rating scales. Patient demographics and other intraoperative and post-operative variables were analysed with Student's t-test and the Mann-Whitney U test. Values of P < 0.05 were considered to indicate statistical significance.

Results: No significant demographic differences were observed. The low-pressure group exhibited lower post-operative pain (P < 0.01) and reduced analgesia requirements (P = 0.00). On analysis of the surgeon rating scale, no disparities were evident between the groups. NMB usage correlated with height and weight (P < 0.01). Heart rate showed no intergroup differences. The MAP measured after 15 min was lower in Group L, and the difference was significant (P = 0.023). The SAP measured after 30 min was lower in Group L, and the difference was significant (P = 0.017). Blood gas values and surgical field visibility were unaffected by the IAP. The positive correlations between NMB, height and weight aligned with previous research.

Conclusion: This study highlights successful laparoscopic cholecystectomy under low IAP, deep NMB and favourable post-operative outcomes. Despite these limitations, the findings contribute to optimising laparoscopic surgical approaches.

Introduction: Awake video-assisted thoracoscopic surgery (VATS) helps to avoid the adverse effects of general anaesthesia (GA) with single-lung ventilation. Its usage in anatomic and non-anatomic pulmonary resections has spread worldwide, and it is mostly performed under thoracic epidural analgesia (TEA). We herein report our surgical experience with awake VATS non-anatomical resections under the thoracic paravertebral block (TPB).

Patients and methods: This retrospective, single-centred study reviewed patients undergoing awake VATS non-anatomical pulmonary resection under TPB, who voluntarily accepted awake VATS despite being suitable for GA and were found unsuitable for GA based on pre-operative assessment results. Demographic, pre-, per- and post-operative data were collected, analysed and compared with the literature data.

Results: Twenty-four patients (16 patients with normal pre-operative assessment results and 8 patients having high risk for GA) were selected. Fourteen bullectomies for recurrent spontaneous pneumothorax and 10 wedge resections (nine for metastasectomy and one for lung biopsy) were performed. Global in-operating room time was 77 ± 31 min. The morbidity rate was 20.8% (n = 5), including prolonged air leak in three and pneumonia in two patients. The mean duration of the chest tube was 1.9 ± 1.5 days and mean duration of hospital stay was 3.5 ± 2.1 days. There was no in-hospital mortality. Our results were mostly similar to the literature data.

Conclusion: Non-anatomical lung resections by VATS can be performed easily and safely under TPB in awake patients. Although the perioperative and post-operative outcomes are not superior to other anaesthesia approaches, preferring TPB may help to avoid the serious potential complications of TEA.

Abstract: Generalised weakness of the abdominal wall can lead to its failure to contain the abdominal viscera within the confines of the abdominal cavity, resulting in simultaneous hernias at different sites. We propose that this entity should be termed 'abdominal wall failure', and the laparoscopic approach is ideal for the management of such a condition. This report presents the case of a patient with concurrent hiatal hernia, bilateral direct inguinal hernias, bilateral femoral hernias and recurrent paraumbilical hernia, managed laparoscopically.

Abstract: While performing an intracorporeal intestinal anastomosis in minimally invasive procedures, surgeons may be encountered with many limitations which made many of them go back to doing extracorporeal anastomosis. In this article, we describe a simple but efficient technique using the Endoclose which improves the surgeon's ability to enhance the anastomosis' exposure while suturing, without having to add extra trocars.

Abstract: Broad ligament hernias (BLHs) are rare internal hernias that can lead to serious complications if left untreated. In this case report, we present the case of a BLH in a female patient and discuss its clinical presentation, diagnosis and management. A 40-year-old woman presented with subacute intestinal obstruction symptoms, including the inability to pass flatus and faeces and recurrent bilious vomiting. A computed tomography (CT) scan confirmed small-bowel obstruction adjacent to the uterus within the left broad ligament. Diagnostic laparoscopy revealed a loop of obstructed small intestine within the broad ligament, which was released and found to be healthy. The defect between the broad and infundibulopelvic ligaments was closed with sutures. The patient had an uneventful recovery and was asymptomatic at a 6-month follow-up. BLHs can be congenital or acquired, with acquired defects often resulting from previous surgeries or pregnancy-related causes. The clinical presentation typically involves the symptoms of bowel obstruction, and a CT scan is the diagnostic modality of choice, showing characteristic findings such as closed-loop obstruction and bowel dilation. Laparoscopic management offers the advantages of faster recovery and less morbidity. Closure of the defect using nonabsorbable sutures is the standard surgical approach, although a wide opening of the defect has also been described. Recurrence is a possibility, particularly if absorbable sutures are used for closure. This case report highlights the importance of early diagnosis and intervention in BLHs to prevent the complications and emphasises the role of laparoscopy in their management.

Introduction: To assess the feasibility and safety of placing a small-sized tube as drainage in patients after uniportal thoracoscopic lung resection.

Patients and methods: Patients who received uniportal video-assisted thoracoscopic surgery (U-VATS) lung resection were identified in our database. Patients placed small-sized tube drainage were compared with those placed conventional chest tube in terms of characteristics, operation modality, post-operative pulmonary complications, post-operative pain, chest tube duration and post-operative hospital stay. Propensity score matching was performed.

Results: Of the 217 enrolled patients, 173 were assigned to the conventional tube group and 44 were assigned to the small-sized tube group. Rates of post-operative pulmonary complications were relatively low and similar between the two groups. After propensity score matching, operation duration was shorter (1 h vs. 1.21 h, P = 0.01) was shorter, and the maximum value of the Visual Analogue Scale (VAS) score after operation (1 vs. 1.5, P = 0.02) and the overall average value of VAS score after operation (0.33 vs. 0.88, P = 0.006) was lower in small-sized tube group. No significant difference was observed in chest tube duration (2 vs. 2, P = 0.34) and post-operative hospital stay (3 vs. 3, P = 0.34).

Conclusions: Compared to conventional chest tubes, small-sized tubes for post-operative drainage after U-VATS lung resection may be a safe and promising approach for reducing post-operative pain.
