Study summary

Acute appendicitis is one of the most common causes of emergency abdominal surgery. Laparoscopic appendectomy is now widely used because it offers advantages such as shorter hospital stay, less postoperative pain, and better cosmetic outcomes. However, the optimal technique for appendiceal stump closure remains unclear, and different methods such as endoloops, clips, sutures, and staplers are currently used in clinical practice.

This randomized controlled trial will compare two commonly used stump closure techniques during laparoscopic appendectomy: hand-made extracorporeal knotting and polymeric clip application. Participants will be randomly assigned in a 1:1 ratio to either group. The study outcomes include failure of technique, postoperative ileus, and intra-abdominal infection within 15 days after surgery.

The aim of this study is to determine whether hand-made extracorporeal knotting is more effective than clip application in reducing postoperative complications related to appendiceal stump closure.

Read the detailed description

Acute appendicitis is a major cause of acute abdomen and a frequent indication for emergency surgery. Laparoscopic appendectomy has become the preferred surgical approach due to advantages such as reduced postoperative pain, quicker recovery, lower wound infection rates, and improved cosmetic outcomes. Despite technical advancements, appendiceal stump leakage remains a serious postoperative concern, potentially resulting in intra-abdominal sepsis and reoperation.

A variety of appendiceal stump closure techniques are in use, including endoloops, sutures, staplers, and clips. Both hand-made extracorporeal knotting and polymeric nonabsorbable clips (Hem-o-lok®) are commonly employed and considered safe. Hand-made extracorporeal knotting has potential advantages of lower cost and usability in resource-limited settings, but the optimal closure technique remains controversial and evidence is limited.

This study is designed as a single-center, prospective, parallel-group randomized controlled trial conducted at Abbas Institute of Medical Sciences, Muzaffarabad. A total of 190 patients aged 10-70 years presenting with acute appendicitis and undergoing laparoscopic appendectomy will be enrolled. After diagnostic laparoscopy and confirmation of eligibility, participants will be randomized by simple lottery method into one of two groups:

Intervention Group: appendiceal stump closure using hand-made extracorporeal knotting (modified Tayside knot), with two knots applied.

Comparator Group: appendiceal stump closure using a nonabsorbable polymeric Hem-o-lok® clip.

Demographic variables, comorbidities, stump diameter, and operative time will be recorded. Outcomes will be assessed intraoperatively and postoperatively, with follow-up continuing until postoperative day 15. The primary outcome is intra-abdominal infection within 15 days. Secondary outcomes include failure of technique during surgery and postoperative ileus.

Statistical analysis will be performed using SPSS software. Categorical variables will be analyzed using a chi-square test, and continuous variables will be summarized as mean ± standard deviation. A p-value ≤ 0.05 will be considered statistically significant.

The findings of this trial may help determine whether hand-made extracorporeal knotting provides superior clinical outcomes or cost advantages compared to polymeric clips, and may guide standardization of appendiceal stump closure techniques in laparoscopic appendectomy, particularly in low-resource surgical settings.

Study arms

  • Experimental
    Hand Made Knot Group

    Appendiceal stump closure using hand-made extracorporeal knotting (modified Tayside knot). Two extracorporeal knots will be applied to secure the appendiceal stump during laparoscopic appendectomy.

    Procedure: Hand-made Extracorporeal Knotting

  • Active comparator
    Arm 2

    Appendiceal stump closure using a nonabsorbable polymeric Hem-o-lok® clip. One clip is applied at the appendiceal stump and a second clip may be added 2-3 mm above the first if needed

    Procedure: Clip Closure

Interventions

  • ProcedureHand-made Extracorporeal Knotting

    Appendiceal stump closure performed using a hand-made extracorporeal knot (modified Tayside knot technique). Two knots will be applied. Used during laparoscopic appendectomy

  • ProcedureClip Closure

    Appendiceal stump closure performed using a nonabsorbable polymeric Hem-o-lok® clip system (Teleflex Medical, USA). The clip is applied to the stump during laparoscopic appendectomy
