Comparison of surgical outcome between conventional laparoscopic cystogastrostomy method and plication of the edge of anterior gastrotomy in patients with pancreatic pseudocyst: A retrospective study at two tertiary care centres

BACKGROUND: In retro-gastric Pancreatic pseudocyst (PP) Laparoscopic cystogastrostomy (LCG) is an established procedure of drainage. AIMS AND OBJECTIVES: To compare surgical outcome between laparoscopic cysto-gastrostomy conventional method and plication of the edge of anterior gastrotomy in patients of pancreatic pseudocyst. MATERIALS AND METHODS: Twenty six patients were underwent LCG from 2010-2020 by a single surgeon. Both the conventional LCG group Group-1(Gr-1) and the plication group Group-2 (Gr-2) where plication of edge of anterior gastrostomy was performed, contained 13 patients each. RESULTS: The numbers of male/female in Gr-1 was 9/4 and that in Gr-2 was 10/3 (P = 1). Mean ages of patients were 45.3 ± 10.4 years (range 23-60) in Gr-1 and 48.0 ± 12.3 years (range 27-65) in Gr-2. Etiological factors were alcohol (46.1% in Gr-1, 53.8% in Gr-2), gallstone disease (38.4% in Gr-1,15.3% in Gr-2), trauma (15.3% in each groups), idiopathic cause (15.3% in Gr-2). The cyst size was 9.0 ± 1.5 cm in Gr-1and 8.9 ± 2.1cm in Gr-2. The mean operative time in Gr-1 (107.6 ± 12.5 minutes) was longer than Gr-2 (97 ± 1 3.6 minutes) (P = 0.06). The size of cystogastric anastomosis in Gr-1 was 4.6 ± 0.7 cm and that in Gr-2 was 4 ± 0.8 cm (P = 0.04). The intra-operative blood loss in Gr-1 and Gr-2 were 101.9 ± 21.7ml and 78.4 ± 30.7 ml respectively. There was a significant change in intraoperative blood loss and stoma size in Gr-2. The postoperative complications were managed conservatively. No recurrence over a period of 18 months of follow-up. CONCLUSION: Plication of edges of anterior gastrostomy result in reduction in operative time, smaller anastomosis without complication and less intra-operative blood loss.
