Shall we use low-pressure CO2 pneumoperitoneum in laparoscopic cholecystectomy?

Abstract

BACKGROUND E AIMS: We aimed to determine whether intraabdominal pressure change caused by pneumoperitoneum created during laparoscopic cholecystectomy (LC) has effects on abdominal and shoulder pain, nausea, vomiting, bowel movements, time of first flatus and defecation, and biochemical parameters.

METHODS: Seventy patients that were diagnosed with cholelithiasis and would undergo LC, between the ages of 18-75, with the Society of Anesthesia Physical Status (ASA) I-III classifications were included in the study. Patients were divided into two groups as whose intervention was defined as low pressure (8-10 mm/hg) and whose intervention was defined as high pressure (14-16 mm/hg). Differences in the prognoses of patients in both groups were observed for statistical significance.

RESULTS: Shoulder pain- visual analogue scale (VAS) values in 6th and 24th hours were lower in Group 1(p<0.005).

There was no significant difference in abdominal pain-VAS values(p≥0.05). Mean intraoperative end-tidal carbon dioxide (ETCO2) values were higher in Group 2 (p<0.005). Differences in nausea and vomiting were not significant(p≥0.05).

There was no significant difference in the first flatus times(p≥0.05). Bowel movements resumed earlier in Group 1(p<0.005). Changes were not significant for biochemical blood parameters in the preoperative and postoperative periods(p≥0.05).

CONCLUSION: The use of low-pressure and high pressure carbon-dioxide (CO2)-pneumoperitoneum created during LC does not cause a significant difference in terms of clinical and laboratory results. Therefore, the surgical team should prefer an easy-to-apply pressure level which they are used to and in which they have low complication rates.
