Effect of emergency general surgery on postoperative performance status in patients aged over 90 years.

Background: Functional deterioration following emergency general surgery (EGS) poses a significant challenge in super-elderly patients. However, limited research has focused on assessing the deterioration in postoperative performance status (PS). This study aimed to investigate the impact of EGS on PS deterioration in super-elderly patients, and the extent to which deteriorated PS is recovered. Methods: This historical cohort study comprised 77 super-elderly patients who underwent EGS between July 2015 and December 2020. Functional deterioration was evaluated by comparing preoperative and postoperative Eastern Cooperative Oncology Group Performance Status (ECOG-PS). The Emergency Surgical Score (ESS) was used as a risk-adjustment tool. Questionnaires were mailed to the patients and their families to assess post-discharge PS and obtain their impressions of EGS. Results: Postoperative PS deteriorated in 35/77 patients (45.5 %). Significant differences were observed between the groups in terms of sex, serum C-reactive protein (CRP) levels, ESS scores, preoperative ECOG-PS, duration of operation, and major complications. Multivariate analysis of preoperative factors showed that ESS ≥7 (OR: 3.7, 95 % CI: 1.0-13), preoperative ECOG-PS ≤2 (OR: 5.9, 95 % CI: 1.7-21), and female sex (OR: 5.8, 95 % CI: 1.6-21) were associated with postoperative ECOG-PS deterioration. According to the questionnaire results, PS recovery post-discharge was observed in 6/36 (17 %) patients, and 34/36 (94 %) patients and their families expressed positive impressions of EGS. Conclusions: EGS in super-elderly patients highly caused a deterioration in their PS, particularly in patients with maintained preoperative PS. PS hardly recovered; however, most patients and their families had positive impressions of the EGS. Key message: We assessed the pre- and postoperative performance status of super-elderly patients who underwent emergency general surgery. Surgery caused a marked deterioration in patients' functional performance, which seldom recovered postoperatively.

Partial duodenectomy with seromyotomy by the "lift-and-cut" method for superficial nonampullary duodenal epithelial tumors: A novel technique.

INTRODUCTION: The therapeutic strategy for superficial nonampullary duodenal epithelial tumors remains controversial. We developed a novel surgical technique for superficial nonampullary duodenal epithelial tumors. We report the initial two cases managed with this method. MATERIALS AND SURGICAL TECHNIQUE: We endoscopically confirmed the tumor location and circumferentially incised the seromuscular layer of the duodenum along it. After circumferential seromyotomy, the submucosal layer was expanded by endoscopic insufflation, and the target lesion was sufficiently lifted. The submucosal layer, including the target lesion, was stapled and resected after confirming the absence of problems with endoscopic passage. The seromuscular layer was continuously sutured to bury and reinforce the stapler line. Single-incision laparoscopic surgery was performed in one case. The resected specimens measured 52 × 32 mm and 50 × 26 mm with negative surgical margins. Both patients were discharged without complications and demonstrated no evidence of stenosis. DISCUSSION: Compared with previously reported procedures, this method of partial duodenectomy with seromyotomy for superficial nonampullary duodenal epithelial tumors is promising, simple, and safe.

Evaluating the outcomes of primary anastomosis with hand-sewn full-circular reinforcement in managing perforated left-sided colonic diverticulitis.

Background: It is a challenge to avoid stoma formation in emergency surgery of perforated left-sided diverticulum. The hand-sewn full-circular reinforcement of the colorectal anastomosis is used during complete pelvic peritonectomy to avoid a diverting ileostomy. This study examined the effect of applying the reinforcement method to perforated left-sided colonic diverticulitis with respect to the permanent stoma rate and cost-effectiveness. Materials and methods: This historical cohort study examined all patients who underwent emergency surgery for perforation of a left-sided diverticulum at the Hyogo Prefectural Amagasaki General Medical Center between July 2015 and September 2019. The cohort was divided into two groups: those who underwent conventional method (Group F) and those for whom the hand-sewn full-circular reinforcement method was actively performed (Group L). Results: The number of patients who underwent emergency surgery which did not lead to an ostomy increased significantly from 12% (3/25) in Group F to 42% (11/26) in Group L (P = 0.0015). The rate of permanent stoma decreased from 80% in Group F to 27% in Group L (P < 0.001). Total treatment costs for patients under the age of 80 in Group L were significantly lower than those in Group F (2170000 ± 1020000 vs 3270000 ± 1960000 JPY; P = 0.018). Conclusions: In emergency surgery for left-sided perforated colonic diverticulitis, applying the hand-sewn full-circle reinforcement of the anastomotic site may reduce stoma formation at the initial surgery and consequently decrease permanent stoma rate and contribute to cost-effectiveness without increasing complications such as anastomotic leakage.
