Laparoscopic Completion Total Gastrectomy as a Standardized Procedure for Gastric Stump Cancer: A Case Control Study

Objective

Complete gastrectomy for gastric stump cancer (GSC) can be challenging due to severe adhesions; therefore, advanced techniques are required when being performed by laparoscopic surgery. This study aimed to evaluate the clinical outcomes of laparoscopic completion total gastrectomy (LCTG) for the treatment of GSC.

Methods

Patient records from January 2010 to October 2018 were retrospectively evaluated. The patients were classified into 2 groups depending on whether they underwent open or laparoscopic gastrectomy. We compared patient characteristics; operative, clinical, and pathological data between the groups.

Results

Twenty open and 17 LCTGs were performed. Laparoscopic gastrectomy resulted in a significantly longer operation time (230 versus 182.5 min; P = 0.026), lower blood loss (14 versus 105 mL; P < 0.001), and shorter period to the first flatus passage (2 versus 3 days; P < 0.001) than open gastrectomy. No significant differences in the number of retrieved lymph nodes, duration of hospital stay, complication rate, and postoperative analgesic usage between the 2 groups were observed. No patients required conversion to open surgery in the laparoscopic-treatment group. Pathologic findings revealed that the laparoscopic group had a smaller tumor size (not pathologic T category) and fewer metastatic lymph nodes than the open group, leading to an earlier distribution of the pathologic stage in the laparoscopic group.

Conclusions

LCTG for the treatment of GSC was safely conducted with fewer complications and mortalities than previously reported results. Advanced technologies and sophistication of laparoscopic skills may further yield minimal invasiveness with better short-term outcome.

Surgical resection of gastric stump cancer following proximal gastrectomy for adenocarcinoma of the esophagogastric junction

BACKGROUND

Proximal gastrectomy (PG) is performed widely as a function-preserving operation for early gastric cancer located in the upper third of the stomach and is an important function-preserving approach for esophagogastric junction (EGJ) adenocarcinoma. The incidence of gastric stump cancer (GSC) after PG is increasing. However, little is known about the GSC following PG because very few studies have been conducted on the disease.

AIM

To clarify clinicopathologic features, perioperative complications, and long-term survival rates after the resection of GSC following PG.

METHODS

Data for patients with GSC following PG for adenocarcinoma of the EGJ diagnosed between January 1998 and December 2016 were retrospectively reviewed. Multivariate analysis was performed to identify factors associated with overall survival (OS). GSC was defined in accordance with the Japanese Gastric Cancer Association.

RESULTS

A total of 35 patients were identified. The median interval between the initial PG and resection of GSC was 4.9 (range 0.7-12) years. In 21 of the 35 patients, the tumor was located in a nonanastomotic site of the gastric stump. Total gastrectomy was performed in 27 patients; the other 8 underwent partial gastrectomy. Postoperative complications occurred in 6 patients (17.1%). The tumor stage according to the depth of tumor invasion was T1 in 6 patients, T2 in 3 patients, T3 in 9 patients, and T4 in 17 patients. Lymph node metastasis was observed in 18 patients. Calculated 1-, 3-, and 5-year OS rates were 86.5%, 62.3%, and 54.2%, respectively. Multivariate analysis showed advanced T stage to be associated with OS.

CONCLUSION

This study reveals the characteristics of GSC following PG for adenocarcinoma of the EGJ and suggests that a surgical approach can lead to a satisfactory outcome.
