ABSTRACT
Objective: This study aimed to explore the short-term clinical efficacy of modified Kamikawa anastomosis and double tract anastomosis after laparoscopic proximal gastrectomy. Methods: A retrospective analysis was carried out by collecting the clinical and pathological data of 42 patients who underwent laparoscopic proximal gastrectomy after admission in our centre from May 2020 to October 2022. Among the 42 enrolled patients, 22 underwent modified Kamikawa anastomosis (modified Kamikawa group), and the other 20 underwent double tract anastomosis (double tract group). Outcome measures included intraoperative condition, postoperative recovery, postoperative quality of life, postoperative nutritional status and gastroesophageal reflux. The patients were followed up using outpatient examination and telephone interviews to identify their nutritional status, reflux esophagitis and anastomotic status. Results: (1) Intraoperative condition: Compared with the double tract group, the modified Kamikawa group had significantly prolonged time for operation and digestive tract reconstruction. However, no statistically significant difference in intraoperative blood loss was found between the two groups. (2) Postoperative recovery: Compared with the double tract group, the modified Kamikawa group had a significantly shorter time for the first postoperative intake of fluids, drainage tube placement and postoperative hospital stay. No statistically significant difference in the time to first postoperative anal exhaust and postoperative complications was found between the two groups. (3) Postoperative quality of life: Compared with the double tract group, the modified Kamikawa group showed better quality of life at 12 months after surgery. (4) Postoperative nutritional status and gastroesophageal reflux: No statistically significant difference in hemoglobin, total serum albumin, albumin, body mass index, MUST score, PG-SGA score, grading of reflux esophagitis using the Los Angeles classification system and GERD score was found between the two groups at 6 and 12 months after surgery. All patients did not experience anastomotic stenosis and tumour recurrence or metastasis. Conclusions: Modified Kamikawa anastomosis is a safe and feasible treatment in laparoscopic proximal gastrectomy, which can ensure good postoperative anti-reflux effect and nutritional status. It has the advantage of better postoperative recorvery and quality of life compared with double tract anastomosis.
ABSTRACT
PURPOSE: To compare the surgical safety and postoperative quality of life (QOL) between side overlap anastomosis (SOA) and double-tract anastomosis (DTA) after laparoscopic proximal gastrectomy (LPG). METHODS: This retrospective cohort study included 43 patients with proximal gastric cancer (PGC) who underwent LPG and were admitted to the Second Affiliated Hospital of Fujian Medical University between August 2020 and December 2022 were in. Their clinical and follow-up data were collected. The patients were divided into the modified SOA (mSOA) (n = 20) and DTA (n = 23) groups based on the anastomosis methods used. The main outcome measures included the QOL of patients 1 year after surgery, and the evaluation criteria were based on the postgastrectomy syndrome assessment scale. Secondary outcome measures included intraoperative and postoperative conditions, postoperative long-term complications and nutritional status 3, 6 and 12 months after surgery. RESULTS: No significant differences were observed in intraoperative and postoperative conditions (P > 0.05) between the mSOA and DTA groups. The mSOA group showed a decreased incidence of reflux esophagitis 1 year after surgery compared with the DTA group (P < 0.05), and no statistically significant differences were noticed between the two groups in terms of other postoperative complications (P > 0.05). The mSOA group showed better QOL when compared with the DTA group (P < 0.05). No significant differences were recorded in postoperative nutritional status between the two groups (P > 0.05). CONCLUSION: The efficacy and safety of LPG with mSOA for PGC were comparable. When compared with the DTA group, the mSOA group seems to show reduced incidence of gastroesophageal reflux and improved QOL, which makes mSOA one of the ideal surgical methods for PGC.
ABSTRACT
BACKGROUND: Double tract anastomosis (DTA) is a recently revisited reconstruction method for preventing reflux esophagitis in laparoscopy-assisted proximal gastrectomy (LAPG). However, only few studies have shown the advantages of LAPG-DTA. PATIENTS AND METHODS: Seventeen patients underwent LAPG-DTA compared to 17 patients undergoing laparoscopy-assisted total gastrectomy (LATG) matched with preoperative stage. Laboratory results, including hemoglobin, serum ferritin, serum iron and vitamin B12, were compared. RESULTS: Reflux esophagitis developed in two and one patient in the LAPG-DTA and LATG groups, respectively. In the laboratory analysis, fewer patients experienced decrease of serum ferritin below the low normal limit in the LAPG-DTA group. There was a significantly lower proportion of patients in the LAPG-DTA group whose vitamin B12 level decreased below the low normal limit. CONCLUSION: LAPG-DTA has the advantages of allowing absorption of iron and vitamin B12 without reflux esophagitis in proximal early gastric cancer compared to LATG.
