Acute appendicitis is one of the most common surgical emergencies encountered in general surgical practice across the world. It represents a major cause of acute abdomen requiring prompt surgical intervention. The lifetime risk of developing acute appendicitis is approximately 7–8%, with the highest incidence seen in the second and third decades of life. Despite advances in diagnostic modalities and antibiotic therapy, appendectomy remains the definitive treatment for acute appendicitis. The vermiform appendix is a narrow, blind-ended tubular structure arising from the posteromedial wall of the caecum. Although its exact physiological function is not fully understood, it is believed to play a role in gut immunity. Acute appendicitis most commonly results from obstruction of the appendiceal lumen due to fecaliths, lymphoid hyperplasia, foreign bodies, or rarely neoplasms. This obstruction leads to increased intraluminal pressure, bacterial proliferation, ischemia, inflammation, and eventual perforation if untreated. Clinically, acute appendicitis typically presents with periumbilical pain migrating to the right iliac fossa, associated with anorexia, nausea, vomiting, fever, and localized tenderness at McBurney’s point. Diagnosis is primarily clinical but is supported by laboratory investigations and imaging modalities such as ultrasonography and computed tomography. Early and accurate diagnosis is essential to prevent complications such as gangrene, perforation, appendicular abscess, and generalized peritonitis. Since the late 19th century, open appendectomy has been the standard surgical treatment for acute appendicitis. First described by Charles McBurney, open appendectomy involves removal of the appendix through a right lower quadrant incision. It is a simple, widely practiced, and effective procedure, especially in emergency settings. However, it is associated with certain disadvantages such as larger incision, increased postoperative pain, higher wound infection rates, longer hospital stay, and delayed return to normal activities. The advent of minimally invasive surgery has revolutionized the management of abdominal surgical conditions. Laparoscopic appendectomy was first performed by Kurt Semm in 1983 and has since gained widespread acceptance. This technique involves removal of the appendix using small trocar incisions under video guidance. Over the years, improvements in laparoscopic instruments and surgical expertise have made this procedure increasingly safe and feasible even in complicated cases. Laparoscopic appendectomy offers several potential advantages over open appendectomy, including reduced postoperative pain, smaller surgical scars, decreased wound infection rates, earlier return of bowel function, shorter hospital stay, and faster recovery.1 Additionally, laparoscopy allows better visualization of the abdominal cavity, which is particularly useful in cases where the diagnosis is uncertain or when other intra-abdominal pathology is suspected. Despite these advantages, concerns still exist regarding laparoscopic appendectomy, including longer operative time, higher equipment costs, technical difficulty, and potential risk of intra-abdominal abscess formation, particularly in complicated appendicitis.2 In resource-limited settings, these factors may influence the choice of surgical approach. In India and other developing countries, both laparoscopic and open appendectomy are widely practiced depending on available resources, surgeon expertise, and patient factors. Therefore, comparative evaluation of these two techniques is important to determine the most effective and practical approach in routine clinical practice.3 The present study was undertaken to compare laparoscopic appendectomy and open appendectomy in patients with acute appendicitis, with special emphasis on operative outcomes, postoperative complications, and recovery parameters.4 The aim is to evaluate which surgical approach provides better clinical outcomes and faster recovery, thereby helping in evidence-based decision-making in the management of acute appendicitis.

Study Design This study was designed as a prospective comparative observational study conducted to evaluate and compare the outcomes of laparoscopic appendectomy and open appendectomy in patients diagnosed with acute appendicitis. The study was carried out in the Department of General Surgery at N.K.P Salve Institute of Medical Sciences & Research Centre & Lata Mangeshkar Hospital, Nagpur, over a period of 12 months. Patients presenting with clinical and radiological features suggestive of acute appendicitis and fulfilling the eligibility criteria were enrolled consecutively after obtaining informed written consent. A total of 100 patients were included in the study and were allocated into two groups based on the surgical procedure performed: • Group A (Laparoscopic Appendectomy Group): 50 patients underwent laparoscopic appendectomy. • Group B (Open Appendectomy Group): 50 patients underwent conventional open appendectomy. Preoperative demographic data, clinical findings, laboratory investigations, and imaging results were recorded for all participants. Both groups were followed prospectively from admission until discharge and during the postoperative follow-up period. The primary outcome measures included postoperative complication rates such as wound infection, intra-abdominal abscess formation, postoperative ileus, and overall morbidity. Secondary outcome measures included operative duration, postoperative pain, duration of hospital stay, and time required to return to normal daily activities. All surgeries were performed by experienced general surgeons using standard operative techniques. Postoperative management protocols, including antibiotic administration, analgesia, and discharge criteria, were standardized as far as possible to minimize bias. Data collected during the study were entered into a structured proforma and analyzed using appropriate statistical methods. Continuous variables were expressed as mean ± standard deviation, while categorical variables were presented as frequencies and percentages. Statistical significance was determined using Student's t-test and Chi-square test, with a p-value of less than 0.05 considered statistically significant. The study was conducted after obtaining approval from the Institutional Ethics Committee and was performed in accordance with the ethical principles outlined in the Declaration of Helsinki.

Table 1: Demographic Characteristics of Patients Undergoing Laparoscopic and Open Appendectomy Demographic Variable Laparoscopic Appendectomy (n=50) Open Appendectomy (n=50) Total (N=100) p-value Age Group (Years) 18–20 8 (16%) 7 (14%) 15 (15%) 0.891 21–30 18 (36%) 20 (40%) 38 (38%) 31–40 12 (24%) 11 (22%) 23 (23%) 41–50 7 (14%) 6 (12%) 13 (13%) 51–60 5 (10%) 6 (12%) 11 (11%) Mean Age (Years) 28.4 ± 10.2 29.8 ± 11.4 29.1 ± 10.8 0.52 Gender Male 30 (60%) 32 (64%) 62 (62%) 0.68 Female 20 (40%) 18 (36%) 38 (38%) Residence Urban 29 (58%) 27 (54%) 56 (56%) 0.69 Rural 21 (42%) 23 (46%) 44 (44%) Body Mass Index (BMI) <18.5 kg/m² 4 (8%) 5 (10%) 9 (9%) 0.87 18.5–24.9 kg/m² 32 (64%) 31 (62%) 63 (63%) 25–29.9 kg/m² 11 (22%) 10 (20%) 21 (21%) ≥30 kg/m² 3 (6%) 4 (8%) 7 (7%) A total of 100 patients diagnosed with acute appendicitis were included in the study. Among them, 50 patients underwent laparoscopic appendectomy and 50 patients underwent open appendectomy. The majority of patients belonged to the 21–30 years age group, accounting for 38% of the total study population. The mean age of patients in the laparoscopic appendectomy group was 28.4 ± 10.2 years, while in the open appendectomy group it was 29.8 ± 11.4 years. The difference between the two groups was not statistically significant (p = 0.52), indicating comparability with respect to age distribution. Regarding gender distribution, males constituted 62% of the study population, whereas females represented 38%. In the laparoscopic group, 60% were male and 40% were female, while in the open appendectomy group, 64% were male and 36% were female. The difference was not statistically significant (p = 0.68). Most participants were from urban areas (56%), whereas 44% belonged to rural areas. The distribution of residence was comparable between the two groups (p = 0.69). Body Mass Index (BMI) analysis showed that the majority of patients (63%) had a normal BMI (18.5–24.9 kg/m²). No statistically significant difference was observed between the groups regarding BMI distribution (p = 0.87). Overall, both study groups were comparable in terms of baseline demographic characteristics, ensuring that postoperative outcomes and recovery parameters could be reliably compared without significant demographic bias. Table 2: Comparison of Operative Outcomes between Laparoscopic Appendectomy and Open Appendectomy Operative Outcome Laparoscopic Appendectomy (n=50) Open Appendectomy (n=50) p-value Operative Time (minutes) 58.2 ± 12.4 51.6 ± 10.8 0.01* Intraoperative Blood Loss (mL) 24.5 ± 8.2 42.8 ± 11.6 <0.001* Postoperative Pain Score (VAS, 0–10) 3.2 ± 1.1 5.8 ± 1.4 <0.001* Time to Oral Feeding (hours) 12.4 ± 3.6 18.9 ± 4.8 <0.001* Duration of Hospital Stay (days) 2.8 ± 0.9 4.5 ± 1.2 <0.001* Time to Return to Normal Activities (days) 10.4 ± 2.6 16.8 ± 3.4 <0.001* Duration of Analgesic Requirement (days) 2.1 ± 0.8 4.3 ± 1.2 <0.001* *Statistically Significant (p < 0.05) Table 2 compares the operative and postoperative outcomes between patients who underwent laparoscopic appendectomy and those who underwent open appendectomy. The mean operative time was slightly longer in the laparoscopic appendectomy group (58.2 ± 12.4 minutes) compared to the open appendectomy group (51.6 ± 10.8 minutes). This difference was statistically significant (p = 0.01). The longer operative duration observed in laparoscopic surgery may be attributed to trocar placement, establishment of pneumoperitoneum, and intracorporeal dissection techniques. The mean intraoperative blood loss was significantly lower in the laparoscopic group (24.5 ± 8.2 mL) than in the open appendectomy group (42.8 ± 11.6 mL) (p < 0.001). The enhanced visualization and precise dissection offered by laparoscopy likely contributed to reduced blood loss. Postoperative pain assessment using the Visual Analog Scale (VAS) demonstrated significantly lower pain scores among patients who underwent laparoscopic appendectomy (3.2 ± 1.1) compared to those who underwent open appendectomy (5.8 ± 1.4) (p < 0.001). This finding reflects the minimally invasive nature of laparoscopic surgery and smaller incision size. Patients in the laparoscopic group resumed oral feeding significantly earlier (12.4 ± 3.6 hours) than patients in the open surgery group (18.9 ± 4.8 hours) (p < 0.001). Early recovery of gastrointestinal function contributed to enhanced postoperative recovery. The mean duration of hospital stay was significantly shorter among laparoscopic appendectomy patients (2.8 ± 0.9 days) compared with open appendectomy patients (4.5 ± 1.2 days) (p < 0.001). Reduced postoperative pain, earlier mobilization, and fewer wound-related complications may explain this difference. Similarly, patients who underwent laparoscopic appendectomy returned to normal daily activities much earlier, with a mean recovery period of 10.4 ± 2.6 days compared to 16.8 ± 3.4 days in the open appendectomy group (p < 0.001). This difference was clinically significant and highlights the socioeconomic benefits of minimally invasive surgery. The duration of postoperative analgesic requirement was also significantly lower in the laparoscopic group (2.1 ± 0.8 days) than in the open appendectomy group (4.3 ± 1.2 days) (p < 0.001), indicating better postoperative comfort and reduced dependence on pain medication. The findings of Table 2 demonstrate that laparoscopic appendectomy offers superior postoperative recovery outcomes compared to open appendectomy. Although the operative time was marginally longer in the laparoscopic group, significant advantages were observed in terms of reduced blood loss, lower postoperative pain, earlier oral intake, shorter hospital stay, decreased analgesic requirement, and faster return to normal activities. These results support the growing preference for laparoscopic appendectomy as the standard surgical approach for uncomplicated acute appendicitis. Table 3: Comparison of Postoperative Complications between Laparoscopic Appendectomy and Open Appendectomy Postoperative Complication Laparoscopic Appendectomy (n=50) Open Appendectomy (n=50) p-value Wound Infection 2 (4%) 7 (14%) 0.04* Intra-abdominal Abscess 1 (2%) 2 (4%) 0.56 Postoperative Ileus 2 (4%) 5 (10%) 0.23 Fever (>38°C) 3 (6%) 8 (16%) 0.11 Seroma Formation 1 (2%) 4 (8%) 0.17 Urinary Retention 1 (2%) 3 (6%) 0.31 Respiratory Complications 0 (0%) 2 (4%) 0.15 Reoperation Required 0 (0%) 1 (2%) 0.31 Overall Complications 5 (10%) 14 (28%) 0.02* *Statistically Significant (p < 0.05) Table 3 presents the comparison of postoperative complications observed in patients undergoing laparoscopic appendectomy and open appendectomy. Wound infection was the most common postoperative complication in both groups. However, its incidence was significantly lower in the laparoscopic appendectomy group, occurring in only 2 patients (4%), compared to 7 patients (14%) in the open appendectomy group. This difference was statistically significant (p = 0.04). Intra-abdominal abscess formation was observed in 1 patient (2%) in the laparoscopic group and 2 patients (4%) in the open appendectomy group. Although the incidence was lower in the laparoscopic group, the difference was not statistically significant (p = 0.56). Postoperative ileus occurred in 2 patients (4%) who underwent laparoscopic appendectomy and in 5 patients (10%) who underwent open appendectomy. The difference did not reach statistical significance (p = 0.23), but a lower trend was noted in the laparoscopic group. Postoperative fever was recorded in 3 patients (6%) in the laparoscopic group and 8 patients (16%) in the open appendectomy group. Although the incidence was higher in the open surgery group, the difference was not statistically significant (p = 0.11). Seroma formation occurred in 1 patient (2%) undergoing laparoscopic appendectomy compared with 4 patients (8%) in the open appendectomy group. The lower incidence in the laparoscopic group may be attributed to smaller incision size and reduced tissue handling. Urinary retention was observed in 1 patient (2%) in the laparoscopic group and 3 patients (6%) in the open appendectomy group. No statistically significant difference was observed (p = 0.31). Respiratory complications such as atelectasis and postoperative chest infection were not observed in the laparoscopic group, whereas 2 patients (4%) in the open appendectomy group developed respiratory complications. This difference was not statistically significant but demonstrated a favorable trend toward laparoscopic surgery. One patient (2%) in the open appendectomy group required reoperation because of postoperative intra-abdominal collection, while no patient in the laparoscopic group required reintervention. The overall postoperative complication rate was significantly lower among patients who underwent laparoscopic appendectomy (10%) compared to those who underwent open appendectomy (28%). This difference was statistically significant (p = 0.02). The results demonstrate that laparoscopic appendectomy is associated with a lower incidence of postoperative complications compared with open appendectomy. The most notable difference was observed in wound infection rates, which were significantly reduced in the laparoscopic group. Other complications such as postoperative ileus, fever, seroma formation, urinary retention, and respiratory complications were also less frequent following laparoscopic surgery. The significantly lower overall complication rate in the laparoscopic group suggests that minimally invasive surgery provides better postoperative outcomes, reduced morbidity, and enhanced patient recovery. These findings support the use of laparoscopic appendectomy as the preferred surgical approach for the management of acute appendicitis whenever appropriate expertise and facilities are available.

Acute appendicitis remains one of the most common surgical emergencies worldwide, and appendectomy continues to be the standard treatment. With the advancement of minimally invasive surgical techniques, laparoscopic appendectomy has increasingly been adopted as an alternative to conventional open appendectomy. The present study was conducted to compare laparoscopic appendectomy and open appendectomy in terms of demographic characteristics, operative outcomes, postoperative complications, and recovery parameters among patients with acute appendicitis. The findings of the present study demonstrate that laparoscopic appendectomy provides significant clinical advantages over open appendectomy. Although the operative duration was slightly longer, laparoscopic surgery resulted in reduced postoperative pain, lower blood loss, earlier oral feeding, shorter hospital stay, faster recovery, reduced analgesic requirements, and fewer postoperative complications. The significantly lower overall complication rate and improved recovery profile observed among laparoscopic patients suggest that minimally invasive surgery offers superior patient outcomes. These findings support the growing body of evidence advocating laparoscopic appendectomy as the preferred surgical approach for the management of acute appendicitis whenever appropriate expertise and facilities are available. Acute appendicitis remains one of the most common surgical emergencies worldwide, and appendectomy continues to be the definitive treatment. With the evolution of minimally invasive surgery, laparoscopic appendectomy has emerged as a widely accepted alternative to open appendectomy. The present study compares both techniques with respect to operative outcomes, postoperative complications, and recovery parameters, and the findings are interpreted in relation to existing literature. In the present study, both groups were comparable in terms of age, gender, and body mass index, ensuring that outcome differences were attributable to surgical technique rather than confounding patient variables. The majority of patients were in the 21–30-year age group, reflecting the known epidemiology of acute appendicitis. Similar age distribution has been reported by Kumar et al. (2018) and Sharma et al. (2019), who observed peak incidence in young adults. The male predominance observed in this study is also consistent with findings of Singh et al. (2020) and international literature, where a higher incidence in males has been documented. This demographic similarity strengthens the validity of outcome comparisons in the present study. The present study demonstrated that laparoscopic appendectomy required a slightly longer operative time compared to open appendectomy. This finding is consistent with Katkhouda et al. (Ann Surg, 2005), who reported increased operative duration in laparoscopic procedures, particularly during the learning curve phase. The increased time in laparoscopy can be attributed to port placement, creation of pneumoperitoneum, and intracorporeal dissection. However, Golub et al. (1998) noted that operative time decreases significantly with increased surgical experience, suggesting that this disadvantage diminishes over time. Importantly, the slightly longer operative time did not adversely affect patient outcomes in the present study. The present study found significantly lower intraoperative blood loss in the laparoscopic group. This finding is supported by Katkhouda et al. (2005) and Gupta et al. (2014), who demonstrated reduced blood loss in minimally invasive appendectomy due to enhanced visualization and precise dissection under magnification. Reduced blood loss contributes to improved postoperative recovery and decreased surgical stress response, further supporting the minimally invasive approach. A significantly lower postoperative pain score was observed in the laparoscopic group. This is in agreement with Bhangu et al. (Lancet, 2015) and Golub et al. (1998), who reported reduced pain and analgesic requirement following laparoscopic appendectomy. The reduced pain is primarily due to smaller incisions, reduced muscle trauma, and minimal tissue handling. This results in earlier mobilization, decreased pulmonary complications, and improved patient satisfaction. The present study demonstrated a significantly shorter hospital stay and earlier return to normal activities in the laparoscopic group. These findings are consistent with Kumar et al. (2018) and Sharma et al. (2019), who reported similar reductions in hospital stay with laparoscopic appendectomy. Bhangu et al. (2015) also emphasized that minimally invasive appendectomy is associated with faster functional recovery and reduced healthcare burden. In developing countries like India, this reduction in hospital stay has significant socioeconomic benefits, including lower treatment costs and improved bed turnover in hospitals. The overall complication rate was significantly lower in the laparoscopic group (10%) compared to the open group (28%). This finding is strongly supported by multiple studies and meta-analyses. Wound infection was significantly lower in the laparoscopic group, which aligns with findings of Katkhouda et al. (2005) and Agrawal et al. (2013). The reduced infection rate is attributed to smaller incisions and minimal exposure of intra-abdominal contents to external contamination. In the present study, intra-abdominal abscess rates were low and comparable between groups. Earlier concerns regarding increased abscess formation after laparoscopic appendectomy, as reported in some early studies, have not been consistently supported in later research. Bhangu et al. (2015) concluded that with proper surgical technique and peritoneal lavage, the risk is not significantly increased. Postoperative ileus, fever, seroma formation, and respiratory complications were less frequent in the laparoscopic group. Although not all differences reached statistical significance, the overall trend favors laparoscopic surgery. Similar observations have been reported by Singh et al. (2020) and Sharma et al. (2019). Earlier return to work and reduced hospital stay observed in the laparoscopic group are important findings with socioeconomic implications. In India, where a large proportion of patients belong to the working population, early recovery translates into reduced loss of wages and improved productivity. Gupta et al. (2014) also highlighted the cost-benefit advantage of laparoscopic appendectomy despite higher initial procedural costs.

Laparoscopic appendectomy is a superior alternative to open appendectomy for the treatment of acute appendicitis, offering reduced postoperative morbidity, faster recovery, shorter hospital stay, and better overall patient outcomes. Although it requires slightly longer operative time and advanced surgical expertise, its overall benefits outweigh these limitations. Therefore, laparoscopic appendectomy should be considered the preferred surgical approach for acute appendicitis whenever facilities and surgical expertise are available.
