Plain English summary of protocol
Background and study aims
This study aims at consenting adult (≥ 18 years old) patients undergoing laparoscopic cholecystectomy due to gallstones or gallbladder polyps. It will involve chewing gum 30 minutes before the procedure to help decrease gastric distention and promote safer surgery through better visualization of vital structures.
Who can participate?
Adult patients (≥ 18 years old) undergoing laparoscopic cholecystectomy due to gallstones or gallbladder polyps
What does the study involve?
Participants will chew gum 30 minutes before their procedure to help decrease gastric distention. The study will compare the outcomes with standard procedures to assess the effects of this intervention.
What are the possible benefits and risks of participating?
While patients may not directly benefit, the study may provide valuable information on the efficacy of chewing gum in decreasing gastric distention before laparoscopic cholecystectomy. This could potentially reduce the use of nasogastric tubes and decrease hospital stay lengths. Risks include common complications of Laparoscopic Cholecystectomy such as:
1. Conversion to open cholecystectomy (2 - 7%)
2. Biliary duct injury (0.4 - 0.6%) or biliary fistulas (0.5%)
3. Vascular injury (0.3%) or postoperative bleeding (0.5%)
4. Intestinal injury (0.09%)
5. Infections (4%)
6. Other complications related to anesthesia and patient comorbidities.
Where is the study run from?
The study will be run from Bulacan Medical Center, City of Malolos, Bulacan.
When is the study starting and how long is it expected to run for?
November 2022 to May 2024

| Scientific title | Effects of chewing gum on gastric distention in patients undergoing laparoscopic cholecystectomy: a single centre study |
| Study objectives | Chewing gum has been proven time and again for use in promoting gastrointestinal motility post-operatively, especially in patients who undergo colorectal surgery. This study aims to use chewing gum preoperatively to decrease gastric distention thereby promoting better visualization of vital structures during laparoscopic cholecystectomy. The hypothesis is that chewing gum will aid in decreasing gastric distention. |

| Health condition(s) or problem(s) studied | The effect of chewing gum on gastric distention in patients undergoing laparoscopic cholecystectomy |
| Intervention | All consenting patients underwent Laparoscopic Cholecystectomy only from November 1, 2022, to May 31, 2024. Participants will undergo random sampling and be assigned to group NG (“no gum”) and group CG (“chewing gum”). Pre-operative Chewing Gum is the intervention. A locally branded xylitol-based mint-flavoured chewing gum was provided to the study participants randomly assigned to the "Chewing Gum" (CG) group by junior general surgery resident doctors to chew for 30 minutes before their transfer to the operating room. The intervention took place in the surgery ward. The intervention was only delivered once, 30 minutes before the patient's scheduled operation. No tailoring was done. There were no modifications done to the intervention during the study. Adherence to the trial participant's chewing of gum was assessed using a checklist accomplished by junior general surgery resident doctors wherein the participant was asked to start chewing their gum under direct observation of the junior general surgery resident and also asked to dispose of their gum after 30 minutes in front of the same observer. |
| Intervention type | Procedure/Surgery |
| Primary outcome measure(s) |
The visual presence of gastric distention during the performance of limited diagnostic laparoscopy measured using nasogastric tubes at the start of the procedure. |
| Key secondary outcome measure(s) |
1. Duration of hospitalization measured using the number of hospital days per patient recorded in study notes at one timepoint |
| Completion date | 31/05/2024 |
