Laparoscopic versus open surgical management of patients with chronic pancreatitis: Amatched case–control study

Abstract

Background: The safety and feasibility of laparoscopic surgery in patients with chronic pancreatitis (CP) have been established, but its outcome has not been compared to that of open surgery. Patients and Methods: This retrospective study was conducted on patients with CP who were treated by a single surgical team from 2012 to 2018. The medical records of patients with surgical treatment of CP were reviewed. Patients were divided into laparoscopic group (LG) and open group (OG). Both the groups were matched for age and procedures. The matched groups were compared. Results: The total number of unmatched patients was 99 and post matching, there were 38 patients in each group. The demographic, aetiological, clinical and laboratory parameters were comparable. The number of each surgical procedure including bilio-enteric anastomosis was also similar. Lateral pancreaticojejunostomy was the most common surgical procedure in both the groups. An additional surgical procedure (bilio-enteric bypass) was required in 10.5% of the patients in LG and 21% of the patients in OG groups (P = 0.3). Significantly lower blood loss (100 vs. 120 ml) and higher operation time (300 vs. 210 min) were observed in LG. The post-operative complication rate was 7.9% in LG group versus 10.5% in OG group. More than 85% of the patients in both the groups had a significant relief from pain. The impact of exocrine and endocrine insufficiency was not remarkable in both the groups. The requirement of an additional surgical procedure was associated with a high conversion rate. Conclusions: The outcomes of laparoscopic surgery in patients with CP were similar to that of open surgery, and requirement of an additional surgical procedure is associated with a high conversion rate.
