A Study of the Safety and Morbidity Profile of Closed versus Open Technique of Laparoscopic Primary Peritoneal Access Port in Patients Undergoing Routine Laparoscopic Cholecystectomy at a Tertiary Care Hospital in Northeastern India.

Introduction: Laparoscopic cholecystectomy (LC) is the gold standard operation for gallstone disease. Primary port placement into the abdomen is a blind procedure and is challenging with chances of unforeseen complications. The complication rate has remained the same during the past 25 years. Both closed/Veress and open/Hasson's techniques are commonly employed and have their typical indications for use.

Materials and methods: This prospective study was carried out in the Department of General Surgery, North Eastern Indira Gandhi Regional Institute of Health and Medical Sciences (NEIGRIHMS), Shillong, from January 2014 to January 2016, with the aim to compare the safety profile of closed/Veress and open/Hasson's methods of access to the abdomen during laparoscopic cholecystectomy (LC). The study had 400 eligible cases undergoing LC who were randomly allotted into 2 groups with 200 cases each: group A: closed/Veress needle method and group B: open/Hasson's method.

Results: Closed/Veress and open/Hasson's method of establishing pneumoperitoneum in laparoscopic cholecystectomy is equally safe in terms of major complications. The closed/Veress method gives faster access to the abdomen as compared to the open method (5.62 ± 2.23 minutes and 7.18 ± 2.52 minutes, respectively, p value <0.0001). The open/Hasson's method is associated with more primary port site complications (9/200 vs. 0/200, p value 0.0036) and troublesome intraoperative gas leaks (39/200 vs. 2/200, p value <0.0001). The open technique for primary peritoneal access port for laparoscopic cholecystectomy does not impart any additional benefits in terms of safety and morbidity profile in patients undergoing LC.

Conclusion: The closed/Veress method of establishing pneumoperitoneum in laparoscopic cholecystectomy is equally safe in terms of major complications and gives quicker access to the abdomen as compared to the open method.
