A Hybrid Technique to Manage a Large Perigraft Seroma after an Open Abdominal Aortic Aneurysm Repair: A Case Report.

Perigraft seroma (PGS) is a relatively rare complication of aortoiliac reconstructive surgery. We, herein, describe a case of a large PGS that was managed by using a hybrid technique of relining the original graft with simultaneous open drainage. An 86-year-old man with a 17.3-cm diameter PGS after prosthetic bifurcated graft replacement for abdominal aortic aneurysm was admitted to our hospital. He presented with abdominal distension and discomfort and had difficulty in taking food. The entire relining of the original covered stent graft with GORE® EXCLUDER® using aortic extension cuff and iliac extenders and simultaneous open evacuation of PGS were successfully performed. The symptoms of the patient totally improved, and no recurrence was detected at 2 years after the operation. This technique would be a feasible treatment option for this rare complication.

Surgical strategy for airway management and bleeding control in penetrating neck injury in zone II: A case report.

We report the case of a 33-year-old man with a self-inflicted neck wound with severe hypopharynx injury, and hemorrhagic shock, which was well managed by a trauma surgeon trained in esophageal surgery. Training in cervical lymph node dissection for esophageal cancer could be useful in the management of penetrating neck injuries.

Planned Versus On-Demand Relaparotomy Strategy in Initial Surgery for Non-occlusive Mesenteric Ischemia.

BACKGROUND: There has been insufficient evidence regarding a treatment strategy for patients with non-occlusive mesenteric ischemia (NOMI) due to the lack of large-scale studies. We aimed to evaluate the clinical benefit of strategic planned relaparotomy in patients with NOMI using detailed perioperative information. METHODS: We conducted a multicenter retrospective cohort study that included NOMI patients who underwent laparotomy. In-hospital mortality, 28-day mortality, incidence of total adverse events, ventilator-free days, and intensive care unit (ICU)-free days were compared between groups experiencing the planned and on-demand relaparotomy strategies. Analyses were performed using a multivariate mixed effects model and a propensity score matching model after adjusting for pre-operative, intra-operative, and hospital-related confounders. RESULTS: A total of 181 patients from 17 hospitals were included, of whom 107 (59.1%) were treated using the planned relaparotomy strategy. The multivariate mixed effects regression model indicated no significant differences for in-hospital mortality (61 patients [57.0%] in the planned relaparotomy group vs. 28 patients [37.8%] in the on-demand relaparotomy group; adjusted odds ratio [95% confidence interval] = 1.94 [0.78-4.80]), as well as in 28-day mortality, adverse events, and ICU-free days. Significant reduction in ventilator-free days was observed in the planned relaparotomy group. Propensity score matching analysis of 61 matched pairs with comparable patient severity did not show superiority of the planned relaparotomy strategy. CONCLUSIONS: The planned relaparotomy strategy, compared with on-demand relaparotomy strategy, did not show clinical benefits after the initial surgery of patients with NOMI. Further studies estimating potential subpopulations who may benefit from this strategy are required.

Comparison of diagnostic accuracy for nonocclusive mesenteric ischemia in models with biomarkers including intestinal fatty acid-binding protein in addition to clinical findings.

BACKGROUND: Nonocclusive mesenteric ischemia (NOMI) is an acute and life-threatening gastrointestinal disorder, requiring rapid therapeutic intervention for ischemic bowel. However, its rapid detection remains challenging. This retrospective, observational study was aimed at comparing the diagnostic accuracy for NOMI in models of biomarkers, including intestinal fatty acid-binding protein (I-FABP), and clinical findings. METHODS: All consecutive patients who presented to the emergency department of the study hospital with suspected NOMI were prospectively enrolled. Receiver operating characteristic analysis compared the diagnostic accuracy of I-FABP with traditional biomarkers (white blood cell count, C-reactive protein, lactate, creatine kinase, and D-dimer) alone and in combination with the baseline model established from clinical findings. RESULTS: Of 96 patients with suspected NOMI, 25 (26.0%) were clinically diagnosed with NOMI. In-hospital mortality was higher in patients with NOMI than those with other conditions (56.0% vs. 4.2%, p < 0.001). Receiver operating characteristic analyses revealed that the I-FABP model had the highest area under the curve (0.805) in the diagnosis of NOMI, compared with other biomarkers. The diagnostic model of clinical findings including age, cardiovascular disease history, undergoing hemodialysis, hypotension, and consciousness disturbance in combination with I-FABP showed the best discrimination (area under the curve, 0.883), compared with other biomarkers. The bootstrap optimism estimate showed the lowest discrimination among the other models with other biomarkers (0.006). CONCLUSION: The usefulness of I-FABP for final diagnosis of NOMI in patients with clinically suspected NOMI at the emergency department was internally validated. Further external validation study is warranted. LEVEL OF EVIDENCE: Diagnostic test, level III.

Laparoscopic completion gastrectomy in elderly patients with remnant gastric cancer: a case series.

BACKGROUND: Open completion gastrectomy (OCG) has been selected to treat remnant gastric cancer (RGC) due to severe adhesions and difficulty recognizing anatomical orientation after primary gastrectomy. In general, elderly individuals' physiological reserves gradually decrease. Moreover, elderly patients (EPs) often have multiple complicating factors (i.e., frailty and comorbidities), leading to more postoperative complications after abdominal surgery. Recently, several trials revealed the advantages of laparoscopic surgery for EPs with gastric cancer in early recovery. However, there are limited studies investigating the use of laparoscopic completion gastrectomy (LCG) for RGC in EPs. This study aims to assess the efficacy of LCG in EPs aged ≥ 70 years. We compared the short- and long-term outcomes of LCG with those of OCG. CASE PRESENTATION: Twenty-one EPs who underwent completion gastrectomy for RGC between 2007 and 2017 were enrolled and classified into two groups according to the surgical approach, namely the LCG (n = 6) and OCG (n = 15) groups. We adopted the G8 geriatric screening tool to comprehensively evaluate the EPs' physical, mental, and social functions. Patient characteristics, clinicopathological characteristics, surgical outcomes, and survival were retrospectively reviewed and compared between groups. RESULTS: There was no significant difference in the preoperative modified G8, indicating that the EPs' backgrounds between the groups were comparable. Of note, blood loss during surgery was significantly reduced in the LCG group [median (range); LCG, 50 ml (20.0-65.0); OCG, 465 ml (264.5-714.0); p = 0.002]. The median number of retrieved lymph nodes in the LCG and OCG groups were 7 (range 4-10) versus 3 (range 1-6), respectively. There were no statistically significant differences in postoperative hospitalization, intake of solid food, and Clavien-Dindo grade ≥ II postoperative complications. In patients with a history of gastrectomy for gastric cancer in the LCG group, operative time tended to be longer in patients who underwent D2 lymph node dissection as primary surgery. CONCLUSIONS: LCG was comparable to OCG for the treatment of RGC in EPs with significantly reduced blood loss. While LCG should be selected with caution in patients who have undergone D2 lymph node dissection as primary surgery, it could be considered as a surgical procedure in EPs with RGC.

Preoperative predictor of extensive resection for acute appendicitis.

BACKGROUND: Appendectomy has been the preferred treatment of acute appendicitis. However, extensive resection (ER) such as an ileocecal resection is sometimes needed. We analyzed the predictive factors of ER. METHODS: This was a retrospective study of 927 patients with acute appendicitis in 7 years. The data collected, including demographic characteristics, laboratory tests, computed tomography (CT) findings and days from onset. RESULTS: ER was performed in 40 patients (4.3%). Age, days from onset, C-reactive protein (CRP), and the presence of several CT findings were significantly higher in the ER group than others (p < 0.01). In a multivariate analysis, four variables (appendiceal mass, non-visualization of appendix, delayed admission, and CRP) retained statistical significance as predictors of ER (p < 0.01). CONCLUSIONS: We demonstrated that the four factors are clinically useful for predicting preoperatively whether or not ER is required. These may help in management decisions, including surgical procedure and anesthesia.
