Overview
Brief Summary
The study is a single-institution prospective, randomised controlled non-inferiority trial conducted at the Department of Surgical Disciplines, AIMS, New Delhi. Sixty patients with primary ventral hernia (European Heria Society classification - umbilical hernia W1 and W2, defect size less than or equal to 4 cm) will be included, randomised into two groups of 35 each. Group A will undergo laparoscopic IPOM plus repair with low-pressure pneumoperitoneum (8-10 mmHg) and deep neuromuscular blockade (NMB), while Group B will undergo standard-pressure pneumoperitoneum (12-14 mmg). Randomisation will follow a computer-generated permuted block sequence (blocks of 10), sealed in envelopes.
Patients will be blinded to the intervention, and pain scores
will be assessed postoperatively by blinded clinicians.
Standard pre-operative workup includes blood tests (LFT, CBC, RFT, CRP, ESR, ete.), informed consent, and adherence to institutional anaesthetic protocols. During surgery, mesh fixation and defect closure will be performed laparoscopically by a skilled surgeon using a standardised approach. Post-operatively, blood markers will be reevaluated at 24 hours, and pain will be assessed using a visual analogue scale at 6 and 24 hours. Postoperative analgesia will be standardised across both groups. Data on operative outcomes, including inflammatory markers, pain, and complications, will be collected and analysed to compare the efficacy of the two techniques.

Outcomes
Primary Outcomes
1.To asses and compare pain during the post operative period at 6 hours and 24 hours post-surgery in two groups A(low pressure pneumoperitoneum with deep neuromuscular blockade) and B (standard pressure pneumoperitoneum)
Time Frame: Post operative period at 6 hours and 24 hours
Secondary Outcomes
- 1.Compare difficulty in performing surgery according to predefined surgical rating scale - likert scale in group A & B(Immediately at the end of surgery)
- 2.Compare operative time( Skin incision to skin closure in minutes) in group A & B(Immediately at the end of surgery)
- 3. Compare rise of inflammatory markers post operatively – CRP in group A & B(24 hours post operatively)
- 4.Proportion of patients in which conversion to standard pressure pneumoperitoneum is required(At the end of data collection i.e. 1 year 6months)
- 5.Compare need for conversion of intracoporeal to transfacial method, for closure of defect in group A & B(Immediately at the end of surgery)
- 6.Compare need for additional analgesia( other than Paracetamol 10-15 mg/kg & diclofenac 1.5-2 mg/kg 1.5-2 mg/kg) in group A & B(6hors & 24 hours post operatively)
