Brief Summary

Laparoscopiccholecystectomy has replaced conventional cholecystectomy as there are limitedsurgical incisions, decreased post-operative stay, less post-operative pain anddecreased need for post-operative analgesia4-6.

 Traditionally, one ofthe first steps in laparoscopic cholecystectomy is the creation ofpneumoperitoneum7 using carbon dioxide (CO2) throughVeress needle8 or through a port (hole) in the abdominal wall.Traditionally, the pressure used is around 15mm Hg (12-16 mm Hg)9.

 The commonly seencomplications due to pneumoperitoneum are shoulder tip pain and cardiopulmonarychanges. These changes seen are directly due to pressure effects on peritoneumand diaphragm and indirectly due to absorbed carbon dioxide and hypercarbia,leading to local peritoneal acidosis, increased intrathoracic pressure,decreased venous return, and decreased cardiac output. These complications maybe well tolerated by healthy and young individuals but lead to significantcomplications in old and those who have underlying cardiopulmonary diseases.

 The increase inintrathoracic pressure depends to some extent on the pressure maintained inpneumoperitoneum due to upward compressive effects of diaphragm. This ledresearchers to think in term of low-pressure pneumoperitoneumcholecystectomies.

 Internationalguidelines recommend that the use of “the lowest intra-abdominal pressureallowing adequate exposure of operative field rather than a routine pressureâ€should be used to minimize the impact of pneumoperitoneum on normal physiologyand the positive impact on postoperative pain10. Low pressurepneumoperitoneum is defined as a pressure of 6-10mm Hg11. The mainconcern about low pressure pneumoperitoneum is its safety in terms ofinadequate exposure resulting in longer than usual operating time, increasedrate of intra-operative complications and also possibly increased frequency ofconversion to open cholecystectomy12. Therefore, attempts are madeto use low pressure pneumoperitoneum in range of 6-10mm Hg in an attempt tominimize alteration of normal physiology and simultaneously to provide anadequate working space.

  In present studyoutcome of the use of low-pressure pneumoperitoneum (LPP defined as 8-10mm Hgin our study) in comparison to the use of standard pressure pneumoperitoneum(SPP defined as 13-15mm Hg in this study) in patients undergoing laparoscopiccholecystectomy are studied.

 Theaim of the current study is to evaluate and compare the effects and outcomes ofLPP versus SPP in laparoscopic cholecystectomy.
