Introduction: Intra-peritoneal onlay mesh repair (IPOM) still remains the most common approach for laparoscopic repair of small to medium sized hernias worldwide. In this study, we compare our early outcomes of an established procedure, i.e. laparoscopic IPOM plus to robotic transabdominal pre-peritoneal (rTAPP) for small to medium sized primary ventral hernia. To compare laparoscopic IPOM plus with rTAPP in terms of pain score, time to ambulate, hospital stay, time to return to work as well as the expenses.

Patients and methods: This is a retrospective analysis of prospectively collected data at our centre between July 2021 and June 2022. Operative time including docking time was recorded. Cost analysis was done in both set of patients. Pain scores were assessed using Visual Analogue Scale (VAS) at regular intervals for up to 3 months and then at the end of 1 year. Time to ambulate, return of bowel function and return to work were documented. Any complication or recurrence during the study period was recorded.

Results: Mean operative time for IPOM plus and rTAPP groups was 59.00 and 73.55 min, respectively. Mean pain score for IPOM at 6, 12 and 24 h was 7.35, 6.81 and 5.77, while for rTAPP, it was 4.73, 3 and 2.55, respectively. VAS scores at 1 week, 1 month and 3 month also showed similar trends. Mean time to ambulate in minutes for IPOM and rTAPP group was 357.69 and 223.64, respectively. Mean hospital stay in days for IPOM and rTAPP was 2.12 and 1.18, respectively. Mean time to return to work in days was 11.77 and 8.45 for IPOM and rTAPP groups, respectively. Expenditure wise, cost of TAPP was more and statistically significant, owing to the use of robotic platform. The mean overall cost of laparoscopic IPOM plus and rTAPP in rupees was 187,177.69 and 245,174.55, respectively.

Conclusion: Robotic TAPP appears an excellent alternative to laparoscopic IPOM plus. Larger studies with long-term follow-up data are further required to reinforce it.

Introduction: Laparoscopic cholecystectomy (LC) is the gold-standard treatment for symptomatic cholelithiasis. To prevent bile duct injuries, various practices are recommended, one of which is the identification of Rouviere's sulcus (RS) and starting dissection above its level. So far, no uniform anatomical description of RS is available in the literature. After prospective observation of 302 patients, we have proposed a new classification based solely on gross morphology. The purpose of this study is to make surgeons well acquainted with its different anatomical variations and its significance for the prevention of complications.

Patients and methods: We performed a prospective analysis of 302 patients during LC, and various morphological variants of RS and its relationship with hepatobiliary anatomy were recorded. We have used the nomenclature as described by previous authors and added a few.

Results: A total of 330 patients were included in our study. We could not visualise the sulcus due to dense adhesion in 28 patients. RS was absent in 24.1% of cases and was present in various forms in 75.8% of cases. Amongst these, the open type was found in 28.8% of cases, fused type was found in 4.8% of cases, groove type was found in 24.8% of cases, pit type was found in 8.2% of cases, close type was found in 14.4% of cases, slit type was found in 8.7% of cases and scar type was found in 10% of cases. Using RS as a landmark, we could perform surgery safely in all cases.

Conclusion: The RS can be described as closed, slit, open, fused, groove, pit or scar type.

Abstract: Spontaneous diaphragmatic hernias (DHs) are uncommon, yet potentially hazardous. To prevent consequences, timely diagnosis and treatment are necessary. A 54-year-old male presented to the emergency room with dyspnoea, cough and tachycardia; he had no history of trauma. Diagnostic imaging revealed a substantial left DH, indicating the need for surgical intervention. The intraoperative examination identified a transverse colon and omentum herniation. Dissection, reduction of the contents, primary sutures of the defect and dual mesh reinforcement accomplished the laparoscopic and thoracoscopic DH repair. This case underscores the importance of timely detection, precise surgical intervention and comprehensive post-operative monitoring when utilising a multidisciplinary approach to manage DHs. It serves as a reminder to exercise caution regarding DHs, particularly in circumstances devoid of traumatic aetiology and the benefits of combined laparoscopic and thoracoscopic approaches.

Abstract: A Spigelian hernia is an uncommon, atypical protrusion of the peritoneum or abdominal contents via a defect (Spigelian fascia), consisting of the internal oblique aponeuroses and the transversus abdominis. With a frequency ranging from 0.12% to 2% of all abdominal wall hernias, Spigelian hernias are extremely rare. It usually arises from a condition that increases intra-abdominal pressure, the degeneration of the abdominal aponeurotic layers or trauma to the abdominal wall. Herein, we present a case series of patients with varying presentations of Spigelian hernia who presented, who were promptly diagnosed and who were managed successfully with laparoscopic surgical repair.

Purpose: We aimed to develop and validate a predictive score to estimate the post-operative recurrence risk after laparoscopic excision of ovarian endometrioma (OMA).

Patients and methods: The prediction score was developed using a training set comprising 431 patients with OMA who underwent laparoscopic surgery at our institution between January 2015 and September 2017. A follow-up period of at least 5 years was required. Clinical data were entered into least absolute shrinkage and selection operator (LASSO) regression to build a scoring system that predicted OMA recurrence. A testing set containing 185 patients from October 2017 to October 2018 was used to assess its performance.

Results: Based on LASSO regression, the final score (ACSAP score) included five clinical predictors (0-15 points): Age, cyst size, previous surgery for OMA, revised American Society for Reproductive Medicine stage and post-operative pregnancy. The area under the curve values of the score were 0.741 (0.765) and 0.727 (0.795) for predicting 3-year and 5-year OMA recurrence, respectively, in the training (testing) set. The score stratified patients into three risk groups in both sets, with significant differences in the 5-year recurrence rates (low-risk, 5.3% [0%]; intermediate-risk, 20.2% [16.5%] and high-risk, 48.0% [36.5%]; P < 0.001). Moreover, patients in the intermediate- and high-risk groups exhibited a significant reduction in the 5-year cumulative recurrence following a minimum of 15-month post-operative medical treatment (both P < 0.05).

Conclusions: The ACSAP score may be a concise and useful tool for identifying patients with a higher risk of OMA recurrence after surgery who might receive long-term post-operative medical treatment.

Introduction: Small and medium sized primary midline ventral hernias are best treated by pre-peritoneal mesh placement. This helps in prevention of complications related to intra-peritoneal mesh placement. The challenges we face while performing laparoscopic transabdominal pre-peritoneal (TAPP) procedure can be overcome by robot-assisted TAPP (rTAPP), and we present our initial experience with the same. We describe the surgical technique used in rTAPP using the relatively new SSI Mantra platform for primary midline ventral hernia repair and evaluate its feasibility and present the outcomes.

Patients and methods: we performed rTAPP for primary midline ventral hernia repair in 10 patients from July 2023 to September 2023. Demographic patient data, hernia characteristics and peri-operative outcomes were measured.

Results: A total of 10 patients underwent elective rTAPP for primary midline ventral hernia, of which 7 were male and 3 were female. The average defect size was 3.2 cm. The average operative time was 113 min. All the patients were discharged within 24-36 h after the procedure. There were no deaths. No post-operative complications such as haematoma, clinically significant seroma, deep or superficial wound infection or recurrence were noted within 30 days.

Conclusion: rTAPP is a technically feasible procedure for the repair of small- and medium-sized midline ventral hernias with defect sizes up to 5 cm. SSI Mantra robotic platform provides the same benefit that other conventional robotic platforms provide at a much lesser cost. Further studies looking at the cost-benefit ratio are required to substantiate the above.

Introduction: Minimally invasive liver resection (MILR) is performed for other gastrointestinal applications. At our centre, all liver resections are systematically performed using a minimally invasive approach. This study aimed to describe our experience in minimising open surgery and emphasised the importance of minimally invasive surgery.

Patients and methods: We retrospectively reviewed 260 patients who underwent liver surgery and compared the surgical outcomes between the open and MILR groups.

Results: A total of 154 patients (68%) underwent MILR. The proportion of patients who underwent prior abdominal surgery and resection was higher in the open surgery group. However, the proportion of patients with liver cirrhosis was similar between the two groups. The MILR group was superior in terms of operative time, blood loss, Pringle manoeuvre rate and mean hospital stay. In addition, major complication and bile leak rates were lower in the MILR group. No significant differences in the tumour size, number of lesions or underlying liver pathology were observed between the two groups.

Conclusion: Acceptable outcomes can be achieved even when the minimally invasive approach is considered the primary option for all patients who require liver resection. Minimally invasive tools are necessary for the modern practice of liver surgery; therefore, laparoscopic or robotic surgery should be included in the armamentarium of liver surgeons.

Background: Median arcuate ligament syndrome (MALS), also known as Dunbar syndrome or celiac artery (CA) compression syndrome, is a rare condition characterized by persistent post-meal or post-exercise abdominal discomfort, often more pronounced during expiration. Additional symptoms include nausea, vomiting, and weight loss.

Aims and objectives: To document the clinical presentation, diagnostic process, and treatment outcomes of seven patients diagnosed with MALS and to evaluate the effectiveness of surgical release of the median arcuate ligament (MAL) over a follow-up period of at least six months.

Materials and methods: The study included seven patients diagnosed with MALS from 2019 to 2021. Diagnosis was based on the presence of chronic abdominal pain and associated symptoms, absence of alternative diagnoses after various clinical assessments, and angiographic evidence of CA compression. The primary treatment involved surgical decompression of the CA by releasing the MAL through either open or laparoscopic techniques.

Results: All seven patients underwent successful surgical release of the MAL. The patients were followed up for at least six months post-surgery. The study evaluated the persistence of symptoms and the need for additional interventions such as revascularization techniques.

Conclusion: Surgical release of the MAL is the primary treatment for MALS, providing relief for many patients. However, long-term follow-up is essential as some patients may continue to experience symptoms post-surgery, necessitating further interventions.

Introduction: Uniportal video-assisted thoracoscopic surgery (U-VATS) has recently become an alternative approach for many minimally invasive thoracic procedures, but although its surgical effectiveness has been proven, still its feasibility and safety are debated and unclear. the objective of this study was to compare the safety and perioperative outcomes of U-VATS versus multiportal VATS (M-VATS).

Patients and methods: This was a comparative follow-up randomised controlled clinical trial, carried out on 36 randomly selected eligible patients, and fulfilling the inclusion and exclusion criteria for VATS, they were assigned randomly into two groups: Study Group I including 18 patients undergoing U-VATS with conventional treatment using standard chest tube drainage and Control Group II including 18 patients undergoing M-VATS) with the same conventional treatment using standard chest tube drainage and served as a comparable control group.

Results: Patients in the U-VATS Group 1 had faster operation time, and with reduced blood loss, pleural drainage and post-operative hospitalisation, they also experienced lower average post-operative pain score on comparison with those in M-VATS Group II (P < 0.001), respectively. For either group, there were no hospital deaths or infections. There was no noticeable difference between the two groups in terms of the number of resected lymph nodes or the rates of intraoperative or post-operative complications (P > 0.05).

Conclusion: U-VATS is feasible and safe in eligible selected patients with favourable short-term perioperative outcomes (operative time, duration of pleural drainage, post-operative pain, early ambulation, duration of hospital stay as well as the risk of perioperative complications), and it can be considered the preferred approach in minimally invasive thoracic procedures that open up for the possibility of fast-track thoracic surgeries.

Abstract: Being one of the most common abdominal surgical procedures, numerous techniques have been adapted to decrease post-operative pain post cholecystectomy. However, the efficacy of intravenous (IV) lidocaine in managing post operative pain after LC is still controversial, according to many recent studies. This study aims to detect the effectiveness of IV lidocaine compared to other medications in managing post-operative pain. PubMed, Scopes, Web of Science and Cochrane Library were searched for eligible studies from inception to June 2023, and a systematic review and meta-analysis was done. According to eligibility criteria, 14 studies (898 patients) were included in our study. The pooled results of the included studies showed that the pain score after 6, 12 and 24 h after the surgery was significantly lower in those who received IV lidocaine as a painkiller (Visual Analogue Scale [VAS] 6H, mean difference [MD] = -1.20, 95% confidence interval [CI] = -2.20, -0.20, P = 0.02; I2 = 98%, VAS 12H, MD = -0.90, 95% CI = -1.52, -0.29, P = 0.004; I2 = 96% and VAS 24H, MD = -0.86, 95% CI = -1.48, -0.24, P = 0.007; I2 = 92%). In addition, IV lidocaine is associated with a significant decrease in the opioid requirement after the surgery (opioid requirements, MD = -29.53, 95% CI = -55.41, -3.66, P = 0.03; I2 = 98%). However, there was no statistically significant difference in the incidence of nausea and vomiting after the surgery between the two groups (nausea and vomiting, relative risk = 0.91, 95% CI = 0.57, 1.45, P = 0.69; I2 = 50%). Lidocaine infusion in LC is associated with a significant decrease in post operative pain and in opioid requirements after the surgery.
