Outcomes of laparoscopic primary gastrectomy with curative intent for gastric perforation: experience from a single surgeon

Perforated gastric cancer: a critical appraisal

Gastric cancer perforation is a life-threatening condition that accounts for less than 5% of all gastric cancer patients and typically requires emergency surgery. However, preoperative diagnosis is difficult and management has a dual purpose: to treat peritonitis and to achieve a curative resection. The optimal surgical strategy is still unclear and prognosis remains poor. A search of the literature was performed using MEDLINE databases (Pubmed, EMBASE, Web of Science and Cochrane) using terms such as "perforated gastric cancer", "perforated gastric cancer and surgery", "perforated gastric tumour" and "gastric cancer perforated". Case reports, other reviews, non-english written papers and papers written before 2010 were excluded. Eight articles published between 2010 and 2020 matched the inclusion criteria for this review. Perforated gastric cancer was more prevalent in elderly males. Distal stomach was most frequently involved. Preoperative diagnosis was uncommon. Mortality rates ranged from 2 to 46%. Patients able to receive an R0 resection demonstrated better long-term survival compared with patients who had simple closure procedures. Laparoscopic procedure was mentioned only in one study. In an emergency situation, curative RO resection should always be offered in patients without multiple adverse factors. A surgical strategy using laparoscopic local repair as first step of surgery to resolve the peritonitis followed by a radical open or laparoscopic gastrectomy with lymphadenectomy could be considered. A balance between emergency and oncological needs should drive the surgical choice on a case by case basis.

Perforation on the superior side of duodenum is a risk factor of laparoscopic primary repair for duodenal ulcer perforation

Purpose

Primary repair is the standard surgical method for treating duodenal ulcer perforations, with very good results usually anticipated because of the simplicity of the associated surgical techniques. Therefore, this study aimed to analyze the risk factors that affect laparoscopic primary repair outcomes for duodenal ulcer perforation.

Methods

Between June 2010 and June 2020, 124 patients who underwent laparoscopic primary repair for duodenal ulcer perforations were reviewed. Early surgical outcomes were evaluated and risk factors for postoperative complications were assessed.

Results

All surgeries were performed laparoscopically without open conversion. Multivariate analysis showed that the elderly (over 70 years), and perforations that needed more than 2 stitches for closure were risk factors for overall postoperative complications. Perforations that needed more than 2 stitches and perforations on the superior side of the duodenum were major risk factors for severe postoperative complications. Severe postoperative complications occurred in 6 of the patients, and 1 of them died of multiorgan failure.

Conclusion

Based on our results, we suggest that laparoscopic primary repair can be safely performed in duodenal ulcer perforation. However, more careful surgery and postoperative care are needed to improve the surgical outcomes of patients who need more than 2 stitches to close their perforation or who have perforations on the superior side of the duodenum.
