External Hemipelvectomy in Soft Tissue Sarcomas: Are They Still Needed?

The development of new technologies, the interpretation of amputations as therapeutic failures by society, and the high morbidity and mortality associated with external hemipelvectomies make these mutilating surgical procedures appear obsolete. Herein, we review the scientific literature on the topic and present two cases of high-grade ulcerated soft tissue sarcomas in the gluteal region which show exceptional behavior and different outcomes. We performed a literature review of the PubMed databases from 2014 to April 2024. Additionally, we present two cases of soft tissue sarcomas in an 18-year-old female patient and in a 71-year-old female patient, which were treated with extended external hemipelvectomies with anterior flap, in combination with an abdominoperineal amputation and a colostomy in one case. After 4 years of follow-up, case 1 is living a relatively normal life. She had an uncomplicated pregnancy and a cesarean section delivery. Case 2 underwent emergency surgery for intestinal perforation and sepsis. She died 2.5 months following the surgery. External hemipelvectomy for soft tissue sarcoma treatment is a demanding surgical procedure with purpose in selected cases after review by multidisciplinary committees and with informed patient consent. This should be similarly individualized and extended to other pathologies when possible.

A novel sandwich technique of minimally invasive surgery for corneal perforation

This study aimed to describe a novel sandwich technique of minimally invasive surgical implantation by using corneal stromal lenticules for corneal perforation. This prospective observational study included nine patients aged 23–79 years (mean, 54 ± 9) from Tianjin Eye Hospital. Corneal stromal lenticules with a central thickness of 120 μm were obtained from small incision lenticule extraction(SMILE). With the corneal perforation as the central point, an iris-repositor was used to manually create a mid-stromal pocket; the stromal lenticular button was gently inserted into the intrastromal pocket and flattened. The graft was sandwiched between the anterior and posterior corneal stromal pockets; the incision was closed using two sutures. The primary health outcome measured in this study was the logMAR best spectacle-visual acuity at 6 months postoperatively. Corneal perforation closure and anterior chamber formation occurred immediately after surgery. No epithelial implantation, infection, or allogeneic rejection was observed during the follow-up. No patients required a penetrating keratoplasty. Anterior segment optical coherence tomography revealed a mean thickness of the grafted tissue of 122 ± 21 μm, with a clear interface in all cases. Comparing the baseline and postoperative 6-month values, the mean logMAR best spectacle-corrected visual acuity was improved from 0.18 ± 0.12 to 0.52 ± 0.31 (P < 0.001). There was significant reduction in the mean manifest spherical equivalent, refractive cylinder, and mean keratometry readings. The novel minimally invasive surgical method for corneal implantation. It was an effective alternative treatment that could restore corneal integrity and improve vision in patients with corneal perforations. This method appears safe, easy, cost- and time-effective, and reliable.

Risk stratification of residual abscess after surgical treatment for gastroduodenal perforation

AbstractAimsResidual abscess is a major complication after emergency surgery for gastroduodenal (GD) perforation. However, there is little evidence regarding potential risk factors contributing to its development. Establishing a risk stratification strategy would be valuable for the entire management process.MethodsThis single‐center, retrospective study analyzed 115 consecutive patients who underwent surgery for GD perforation between 2010 and 2023 at a secondary emergency care hospital. Patients were divided into two groups based on the presence or absence of residual abscesses. Potential risk factors for abscess formation were evaluated from various aspects.ResultsThe incidence of residual abscesses was 19.1% (22 of 115). Multivariable analysis revealed that current use of nonsteroidal antiinflammatory drugs (odds ratio [OR] 3.76, p = 0.037), cancer chemotherapy (OR 13.56, p = 0.005), and preoperative renal dysfunction (OR 4.72, p = 0.018) were independent predictors. A potential scoring model could be created using these three parameters, and the number of risk factors correlated with the likelihood of developing a residual abscess (0 vs. 1 vs. ≥2; 6.2% vs. 29.4% vs. 50.0%, p &lt; 0.001). From a bacteriological point of view, the presence of Enterococcus in the ascites culture was closely related to its occurrence with 100% probability. Moreover, regarding early detection of this complication, C‐reactive protein on postoperative d 5 had the highest predictive ability with an area under the curve of 0.818.ConclusionThe risk of residual abscess formation after surgical treatment of GD perforation can be assessed utilizing both preoperative and postoperative information.

C-reactive Protein/Albumin Ratio Predicts Short-term Postoperative Outcomes and Intraabdominal Abscess Formation in Colorectal Perforation.

This study aimed to investigate preoperative factors, including the C-reactive protein (CRP)/albumin ratio (CAR), associated with postoperative outcomes in patients with colorectal perforation who underwent emergency surgery to improve postoperative prognosis. Twenty-eight consecutive patients who underwent emergency surgery for colorectal perforations were included. We retrospectively investigated the clinical factors associated with their postoperative outcomes. The median patient age was 69.5 years (range, 46.0-93.0 years); 13 patients (46.4%) were males and 15 (53.6%) were females. Colorectal cancer (8 [28.6%]) was the most common cause of colorectal perforation. Postoperative complications were diagnosed in 18 patients (64.3%), with intraabdominal abscess as the most common (6 [21.4%]). Multivariate analysis revealed that CAR (odds ratio, 1.357; 95% confidence interval, 1.056-1.743; p=0.017) was an independent risk factor for postoperative complications. A cutoff value of 4.9 was selected to predict the development of postoperative complications based on the CAR. The proportion of all postoperative complications (p=0.016), postoperative complications of Clavien-Dindo classification grade II or higher (p=0.002), and death during hospitalization (p=0.049) were significantly higher in the group of patients with CAR ≥ 4.9 than in those with CAR < 4.9. Additionally, intraabdominal abscess (p=0.049) was significantly higher in the group of patients with a non-improvement in CAR on postoperative day 3 than in those with an improvement in CAR on postoperative day 3. Perioperative CAR could be a predictor of perioperative complications and death and might be useful in improving the postoperative prognosis of colorectal perforations.

Togetherness Reminded by the Earthquake: Relationship Between Stress and Peptic Ulcer Perforation

Background: Severe stress is one of the leading causes of peptic ulcer perforations. Peptic ulcer perfora-tion is a clinical condition that can be fatal if not treated urgently. This study aimed to investigate the effects of social stress caused by the earthquakes in Kahramanmaraş on peptic ulcer perforation. Materials and Methods: A retrospective evaluation was conducted on 66 peptic ulcer perforation cases operated on in three major centers in Şanlıurfa, considering two large earthquakes that occurred on February 6, 2023, and by comparing the 6-month periods before and after the earthquakes. Patients were assessed in terms of age, gender, diagnostic method, perforation site, surgical technique, operation time, length of hospital stay, and mortality. Our study also evaluated laboratory parameters such as white blood cell (WBC) count, hemoglobin, urea, creatinine, and albumin levels. Results: In the 6 months prior to the earthquakes, 21 patients underwent surgery for peptic ulcer perfo-ration, whereas 45 patients were operated on for the same reason in the 6 months following the earthquakes; there were two deaths in each group. The number of patients operated on after the earthquakes was significantly higher than the number of patients operated on before the earthquakes. Furthermore, the two groups were also compared in terms of demographic data and laboratory findings; no significant differences between the two groups were observed regarding these parameters. Conclusions: Stress plays a remarkable role in the development of peptic ulcer perforation. In stressful situations that affect the general population, such as earthquakes, it is essential to assess stress tenden-cies and dyspeptic complaints in patients presenting to the hospital. Patients with positive findings should undergo endoscopy if necessary, followed by appropriate gastric treatment.

Effectiveness of surgical approach in the management of non-traumatic corneal perforations

ABSTRACT Clinical relevance Non-traumatic aetiologies are one of the leading causes of corneal perforations. The management of corneal perforation is quite challenging and complex for anterior segment surgeons. The appropriate surgical approach for each case is usually determined on the basis of a combination of many different parameters. Background The study aimed to evaluate surgical approach options and outcomes in the treatment of non-traumatic corneal perforations. Methods Patient data who underwent surgery for non-traumatic corneal perforation between 2016 and 2023 were retrospectively evaluated. Medical records were assessed in terms of age, gender, perforation aetiology, the first and last examination notes, surgical approach, follow-up time, and additional surgeries and outcomes according to anatomical, therapeutic and functional success. Anterior segment photographs were investigated for thorough explanation of the examinations. Results Forty-five eyes of 45 patients were included (mean age 61.2 ± 22.4 (90-2), female/male ratio 20/25). Surgical approaches applied according to the size and location of the perforation site included fibrin glue application (6), amniotic membrane transplantation (AMT) (9), corneal patch graft application(15), and tectonic keratoplasty (15). The ratio of inflammatory and infectious causes as the two main indications was 29/16. Globe integrity was ensured with the first surgery in 27 eyes. However, 17 eyes required secondary surgical attempts due to failure of the first approach and 1 eye underwent evisceration. AMT was the least successful method among other methods in anatomical, therapeutic, and functional assessment. Conclusion There are various surgical approaches for repairing non-traumatic corneal perforations, each with its own advantages and disadvantages. These include high tissue resistance, the ability to remove necrotic tissue, ease of access, and anti-inflammatory activity. It is possible to successfully repair corneal perforations with single and combined methods, considering the above-mentioned features, especially depending on the size and location of the defect. While AMT is a viable and time-saving choice − especially in the lack of donor tissues − further interventions are necessary in most circumstances.

Delayed primary skin closure reduce surgical site infection following surgery for gastrointestinal perforation: A systematic review and meta-analysis.

Following surgery for Gastrointestinal (GI) perforation, there is an increased occurrence of Surgical Site Infections (SSI). The beneficial effect of employing delayed primary skin closure (DPC) on severely contaminated incisions subsequent to surgery for GI perforation remains unverified. To systematically evaluate the advantages of the DPC management in surgery for GI perforation. A literature search was performed using ClinicalTrials.gov, Pubmed, Embase, Cocharane, and Web of Science identified all eligible English-language studies related to surgery for GI perforation through October 2023. Randomized clinical trials (RCTs) comparing DPC with primary skin closure (PC) in surgery for GI perforation were included. Two investigators independently performed the inclusion work, and a third investigator was consulted for resolving conflicts. Data were extracted by multiple independent investigators and pooled in a random-effects model. The primary outcome was SSI, defined in accordance with the original studies. The secondary outcome was the length of stay (LOS). Final analysis included 12 RCTs which included a total of 903 patients were randomizing divided into either DPC or PC, including 289 patients with gastroduodenal perforation (32%), 144 patients with small intestine perforation (15.96%), 60 patients with colon perforation (6.64%), and 410 patients with appendix perforation (45.4%). The rates of SSI was significantly decreased after DPC management (OR:0.31, 95%CI:0.15-0.63, p < 0.01), no significant differences were observed between the DPC group and PC group in terms of LOS (MD: - 0.37, 95% CI: - 1.91-1.16, p = 0.63). These results point to the efficacy of DPC management in reducing SSI in patients under surgery for GI perforation, and this strategy did not increase the LOS. This systematic review and meta-analysis may contribute to informed decision-making in the management of severely contaminated wounds associated with GI perforation.

Effect of Preoperative Geriatric Nutritional Risk Index on Prognosis in Patients after Surgery for Lower Gastrointestinal Perforation

Introduction: Geriatric Nutritional Risk Index (GNRI) is a reliable index derived from serum albumin levels, height, and weight. Although various prognostic factors have been studied, the effect of preoperative nutritional status on surgical outcomes remains unexplored. This study aimed to evaluate the efficacy of the GNRI in predicting postoperative outcomes of lower gastrointestinal perforation. Methods: Eighty patients treated at our institution between January 2016 and December 2022 were retrospectively analyzed. This study primarily focused on the correlation between preoperative GNRI and two key outcomes: postoperative hospital stay duration and 1-year mortality rate. Results: Our findings revealed a significant association between low GNRI scores and increased 1-year mortality (odd ratio 4.0, 95% confidence interval [CI] 1.1–16, p = 0.025). Kaplan-Meier analysis and log-rank test showed that patients in the low GNRI group had markedly poorer overall survival rates than those in the high GNRI group (12-month survival rate 0.88 [95% CI: 0.75–0.95] vs. 0.65 [95% CI: 0.47–0.78]; p = 0.018). Additionally, both univariate and multivariate analyses indicated that lower GNRI scores were associated with prolonged hospital stays. Conclusion: We showed that a low GNRI score was associated with high mortality and prolonged hospital stay after emergency surgery for lower gastrointestinal perforation.

Comprehensive management of chronic ear disease: Consecutive patient analysis at a tertiary children's hospital

ObjectiveTo characterize medical complexity and advanced interventions necessary to treat pediatric patients with chronic ear disease. MethodsA retrospective case review of children who received surgery for chronic otitis media, cholesteatoma, or tympanic membrane perforation at a tertiary children's hospital from 2020 to 2024 was performed. The frequency and type of medical complexities as well as distribution and success of advanced otologic interventions were recorded. ResultsOperations were performed on 80 ears. Forty-five percent were in medically complex patients. Twenty-five percent had a syndrome, 13 % had American Society for Anesthesiologists Severity Class 3 or more, and 38 % attended multi-disciplinary programs. Advanced audiology testing protocols were utilized in 53 % of patients, and multiple children received complex sleep and airway operations. Advanced surgical techniques were required in 58 %. Post-operatively, an intact tympanic membrane was achieved in 95 % of operated ears (p < 0.01). Residual and recurrent cholesteatoma were each present in 5 % of cases, with mean follow-up of 11.6 months. Otorrhea reduced from 64 % of patients pre-operatively to 2 % post-operatively (p < 0.01), including cessation in all individuals who reported social/bullying issues related to ear drainage/odor. Unrestricted water exposure was achieved in 99 % of individuals (p < 0.01). Patients showed a mean improvement after surgery of 7.6 dB, as measured by the change in air-bone gap (p < 0.05). Conclusions: Comprehensive treatment of otologic conditions included care that was holistic of all medical needs, integrated with other services, developmentally appropriate, encompassing of non-otologic procedures, technically advanced, effective, and functionally-focused. Surgical teams should endeavor together to provide this combination of services.

Risk Factors for Postoperative Major Morbidity, Anastomotic Leakage, Re-Surgery and Mortality in Patients with Colonic Perforation.

Background/Objectives: This study aimed to determine the risk factors associated with postoperative major morbidity, anastomotic/suture leakage, re-surgery and mortality in patients undergoing emergency surgery for colonic perforation. Methods: A total of 204 adult patients treated surgically for colonic perforation from 2016 to 2021 at the University Hospital Erlangen were included in a retrospective analysis. Patient demographics and pre-, intra- and postoperative parameters were obtained and evaluated among various outcome groups (in-hospital major morbidity, anastomotic/suture leakage, re-surgery and 90-day mortality). Results: Postoperative in-hospital major morbidity, anastomotic/suture leakage, need of re-surgery and 90-day mortality occurred in 45%, 12%, 25% and 12% of the included patients, respectively. Independent risk factors for in-hospital major morbidity were identified and included the presence of any comorbidity, a significantly reduced preoperative general condition, the localization of perforation in the right hemicolon and the need for an intraoperative blood transfusion. The only independent risk factor for anastomotic/suture leakage was the presence of any comorbidity, whereas no independent risk factors for re-surgery were found. An age > 65 years, a significantly reduced preoperative general condition and the need for an intraoperative blood transfusion were independent risk factors for 90-day mortality. Conclusions: Our study identified risk factors impacting postoperative outcomes in patients undergoing emergency surgery for colonic perforation. These patients should receive enhanced postoperative care and may benefit from individualized and targeted therapeutic approaches.

Predictors of Morbidity and Mortality of Gastrointestinal Perforation in Children

Background: Gastrointestinal perforation is a common surgical problem in paediatric surgical ward in our country. It carries a high morbidity and mortality in children. The predictors of postoperative morbidity and mortality are still not well established. Objectives: The objective of this study was to identify the predictors of morbidity and mortality following surgery for gastrointestinal perforation in children. Methods: This was a single centre cross sectional type of descriptive observational study carried out in the Department of Paediatric Surgery, Mymensingh Medical College Hospital with 16-month duration from 1st January, 2017 to April 30, 2018, in children aged from 2-12 years. Predictors related to postoperative morbidity and mortality were investigated. Results: A total of 40 patients were selected for this study with mean age of 8.92±2.61 years. Male: female was 1.5:1. Analysis indicated that factors associated with postoperative morbidity and mortality were low BMI, poor nutritional status, low serum total protein and albumin, delay in seeking treatment and contaminated peritoneal collection. Appendicular perforation was the highest number perforation in 23(57.5%) patients. Ileal perforation was the second highest number 8(20%). Appendectomy was the highest surgical procedure 21(52.5%), followed by resection-anastomosis and wound excision &amp; repair 3(7.5%) each. Serum total protein and albumin were below normal limit among 15(37.5%) and 35(87.5%) patients respectively. 13(32.5%) patients received treatment 72 hours after onset of symptom and 18(45%) patients undergone operation within 24-48 hours of admission. Postoperative complications developed in 30 patients. Among them SSI were in 20(66.66%), SIRS in 9(30%) and leakage of repair in 1(3.33%) patient. Mortality rate was 5%. Conclusion: Poor nutritional status, low total serum protein and albumin, delay in initiation of treatment, and contaminated peritoneal fluid are the predictors of morbidity and mortality of gastrointestinal perforation in children.

A New Self-Expandable Metallic Stent with Low Axial Force and a High Axial Force Zero-Border Shows a Very Low Perforation Rate in Malignant Colorectal Obstruction: A Japanese Multicenter Prospective Study.

Background: Recently, there has been a significant increase in the utilization of self-expandable metallic stents (SEMSs) for treating malignant colorectal obstructions through colorectal stenting. The mechanical properties of SEMSs are usually considered to affect clinical outcomes of patients with malignant colorectal obstructions. Methods: This single-arm, prospective, multicenter study of SEMS with a lower axial force and high axial force zero-border included 200 patients with malignant colorectal obstruction. Technical and clinical success, stent patency, and adverse events associated with SEMS placement were evaluated. Results: One patient was excluded, and 199 patients were evaluated. The treatment intent was bridge-to-surgery in 129 and palliation in 70 patients. Technical and clinical success rates were 99.5% and 97.0%, respectively. The percentage of the ColoRectal Obstruction Scoring System scores of 3 or higher improved significantly from 19.2% before placement to 93.9% after placement. Clinical success was not achieved in five patients due to insufficient stent expansion in four patients and stent occlusion in one patient. Only one patient underwent emergency surgery for perforation of the proximal colon, far from where the stent was placed; the rescue procedure was not performed, despite no improvement in proximal dilatation due to insufficient stent expansion. Among the palliation cohort, 15 patients received chemotherapy, including molecular-targeted agents such as bevacizumab. There were no fatal cases related to stent placement. Conclusions: For management of malignant colorectal obstruction, this newly developed SEMS with low axial force and a high axial force zero-border showed high technical and clinical success rates, and an extremely low perforation rate (0.5%).

Validity of laparoscopic surgery for lower gastrointestinal perforations.

This study aimed to clarify the validity of laparoscopic surgery for lower gastrointestinal perforation by comparing the clinical outcomes of laparoscopic and open emergency surgery. We reviewed the data of patients who underwent surgery for lower gastrointestinal perforation. Patients were categorized into two groups: the laparoscopic group who underwent laparoscopic surgery, and the open group who underwent laparotomy. Clinical and operative outcomes between the two groups were evaluated. A total of 219 patients were included in the study. There were 66 and 153 patients with small bowel and colorectal perforations, respectively. The median operative time in the laparoscopic group was shorter than that in the open group (126 min vs. 146 min, p = .049). The mean amount of intraoperative blood loss was significantly lower in the laparoscopic group (50.4 mL vs. 400.1 mL, p < .001). The incidence of postoperative complication was higher in the open group (20.0% vs. 66.5%, p < .001), especially wound infection (0% vs. 26.3%, p = .002). Median hospital stays were 14 days and 24 days in the laparoscopic and open groups, respectively (p < .001). In the laparoscopic group, hospital mortality was 0%. The laparoscopic approach for small bowel and colorectal perforation in an emergency setting is a safe procedure in carefully selected patients and may contribute to decreased intraoperative blood loss, shortened hospital stay, and decreased incidence of postoperative complications, especially wound infection.

Initial surgery for spontaneous intestinal perforation in extremely low birth weight infants is not associated with mortality or in-hospital morbidities.

Determine short-term outcomes following peritoneal drain (PD), laparotomy (LAP) after PD (PD-LAP), and LAP in extremely low birth weight (ELBW) infants with spontaneous intestinal perforation (SIP). ELBW infants with SIP were identified using the Children's Hospitals Neonatal Database. Mortality and length of stay (LOS) were compared among groups. Of 729 SIP infants from 6/2010-12/2016, 383(53%) received PD, 61(8%) PD-LAP, and 285(39%) LAP. PD infants had lower GA at birth, at SIP diagnosis and upon admission than PD-LAP or LAP; and higher sepsis rates than LAP. Bivariate analysis and Kaplan-Meier survival estimates suggested PD had increased mortality vs. PD-LAP and LAP (27%, 11.5%, and 15.8% respectively, p < 0.001). However, surgical approach was not significantly associated with mortality in multivariable analysis accounting for GA and illness severity. LOS did not differ by surgical approach. In ELBW infants with SIP, mortality, and LOS are independent of the initial surgical approach.

Preliminary investigation of endoscopic surgery for tympanic membrane perforation: Regenerative treatment compared with conventional surgery

PurposeTo compare surgical outcomes of regenerative treatment (RT) including basic fibroblast growth factor (bFGF) (Group-R) with the conventional method (Group-C) for patients with tympanic membrane perforation (TMP), both of whom underwent transcanal endoscopic ear surgery. MethodsThe study population of Group-R included 61 ears of 59 patients treated with RT-TMP in which TMP edges were disrupted mechanically and a gelatin sponge immersed in bFGF was inserted into the TMP. Fibrin glue was then dripped over the sponge. Group-C consisted of 13 patients who underwent conventional surgery before adopting the RT-TMP. Patients' characteristics and outcomes including TMP closure rates, and change in hearing level were evaluated three or more weeks after the surgery. ResultsThe baseline characteristics including size of TMP were not significantly different between the two groups. Although Group-R had significantly shorter operating time than Group-C, the complete TMP closure rates were 69 % (9/13) and 85 % (52/61), respectively. Air-conduction hearing thresholds showed significant improvements, and analysis of variance showed that Group-R achieved significant interactions other than at 8 kHz, implying better improvement in cases with TMP closure. The air-bone gaps also improved at all frequencies in both groups. Specifically, at 4 kHz, there was a trend showing better improvement in Group-R. ConclusionRT-TMP had a high TMP closure rate and good hearing improvement, with no significant differences compared with those of conventional surgery. This new therapy is simple and safe, and requires less operating time, and it could help improve the quality of life of patients with TMP.

Usefulness of laparoscopic surgery for colorectal perforation: a single-center retrospective cohort study.

This study aimed to determine the safety and efficacy of laparoscopic surgery in patients with colorectal perforation owing to a significant lack of evidence in this field. This retrospective cohort study analyzed the data of 70 patients who underwent emergency surgery for colorectal perforations between January 2017 and December 2023. The surgical outcomes of the patients who underwent open and laparoscopic surgeries were statistically compared. The primary endpoints were postoperative mortality and complications. The secondary endpoints included blood loss, surgical time, length of hospital stay, and 1-year overall survival. Overall, 28 patients underwent open surgery and 42 underwent laparoscopic surgery. No significant difference was noted in the postoperative mortality or overall rate of severe complications between the two groups. The incidence of superficial and deep incisional surgical site infection was lower in the laparoscopic surgery group (35.7% vs. 0.0%, p < 0.001), while the surgical time was significantly longer in the laparoscopic group (175.6 ± 92.2min vs. 290.0 ± 102.3min, p < 0.001). No significant differences were found in blood loss, length of hospital stay, or 1-year overall survival. Laparoscopic surgery for colorectal perforation markedly reduced superficial and deep incisional surgical site infection, with no substantial difference in mortality or severe complications.

Time-to-surgery paradigms: wait time and surgical outcomes in critically Ill patients who underwent emergency surgery for gastrointestinal perforation

BackgroundWaiting time for emergency abdominal surgery have been known to be linked to mortality. However, there is no clear consensus on the appropriated timing of surgery for gastrointestinal perforation. We investigated association between wait time and surgical outcomes in emergency abdominal surgery.MethodsThis single-center retrospective cohort study evaluated adult patients who underwent emergency surgery for gastrointestinal perforations between January 2003 and September 2021. Risk-adjusted restricted cubic splines modeled the probability of each mortality according to wait time. The inflection point when mortality began to increase was used to define early and late surgery. Outcomes among propensity-score matched early and late surgical patients were compared using percent absolute risk differences (RDs, with 95% CIs).ResultsMortality rates began to rise after 16 h of waiting. However, early and late surgery groups showed no significant differences in 30-day mortality (11.4% vs. 5.7%), ICU stay duration (4.3 ± 7.5 vs. 4.3 ± 5.2 days), or total hospital stay (17.4 ± 17.0 vs. 24.7 ± 23.4 days). Notably, patients waiting over 16 h had a significantly higher ICU readmission rate (8.6% vs. 31.4%). The APACHE II score was a significant predictor of 30-day mortality.ConclusionsAlthough we were unable to reveal significant differences in mortality in the subgroup analysis, we were able to find an inflection point of 16 h through the RCS curve technique.Trial registrationFormal consent was waived due to the retrospective nature of the study, and ethical approval was obtained from the institutional research committee of our institution (B-2110–714-107) on 6 October 2021.

Stage IV gastric adenocarcinoma with enteroblastic differentiation with 5-year relapse-free survival after D2 gastrectomy and chemotherapy: A case report

BackgroundGastric adenocarcinoma with enteroblastic differentiation (GACED), a rare subtype of gastric cancer, is associated with a more aggressive behavior than conventional gastric adenocarcinomas. We report a rare case of stage IV GACED treated with D2 gastrectomy and postoperative chemotherapy.Case presentationA 39-year-old woman with acute upper abdominal pain immediately underwent surgery for gastric perforation. Afterward she was diagnosed with adenocarcinoma of the pylorus. D2 gastrectomy was performed and the final pathological diagnosis was stage IV GACED with positive peritoneal cytology. Postoperative chemotherapy was initiated with S1 plus oxaliplatin for 1 year, which was ceased thereafter to enhance her quality of life. The patient survived more than 5 years without relapse after gastrectomy.ConclusionsStage IV GACED, determined by positive spalt-like transcription factor 4, can be successfully treated with surgery and chemotherapy.

Pathophysiology and surgical outcomes of patients with fungal peritonitis from upper gastrointestinal tract perforation: a retrospective study.

To compare the pathophysiology and surgical outcomes of emergency surgery for upper gastrointestinal tract perforation with and without fungal peritonitis and identify the risk factors for fungal peritonitis. The subjects of this retrospective study were patients with upper gastrointestinal perforation and peritonitis who underwent emergency surgery at a single medical center in Japan. The patients were allocated to two groups according to the presence or absence of fungal peritonitis: group F and group N, respectively. At the time of surgery, ascitic fluid culture or serum β-D glucan levels were available for 54 patients: 29 from group F and 25 from group N, respectively. The stomach was perforated in 14 patients (25.9%) and the duodenum was perforated in 40 patients (74.1%). Group F had a higher proportion of patients with low preoperative prognostic nutritional index scores (≤ 40) and C-reactive protein levels and a higher postoperative complication rate. The time to initiate food intake and the postoperative hospital stay were also significantly longer in group F. Multivariate analysis identified that the perforation site of the stomach was a risk factor for fungal peritonitis. Patients with fungal peritonitis from upper gastrointestinal tract perforation had higher postoperative complication rates, delayed postoperative recovery, and a longer hospital stay. Gastric perforation was a risk factor for fungal peritonitis.

Prognostic significance of preoperative osteosarcopenia on patient' outcomes after emergency surgery for gastrointestinal perforation.

Sarcopenia is a prognostic predictor in emergency surgery. However, there are no reports on the relationship between osteopenia and in-hospital mortality. This study clarified the effect of preoperative osteosarcopenia on patients with gastrointestinal perforation after emergency surgery. We included 216 patients with gastrointestinal perforations who underwent emergency surgery between January 2013 and December 2022. Osteopenia was evaluated by measuring the pixel density in the mid-vertebral core of the 11th thoracic vertebra. Sarcopenia was evaluated by measuring the area of the psoas muscle at the level of the third lumbar vertebra. Osteosarcopenia is defined as the combination of osteopenia and sarcopenia. Osteosarcomas were identified in 42 patients. Among patients with osteosarcopenia, older and female patients and those with an American Society of Anesthesiologists Physical Status of ≥ 3 were significantly more common, and the body mass index, hemoglobin value, and albumin level were significantly lower in these patients than in patients without osteosarcopenia. Furthermore, the osteosarcopenia group presented with more postoperative complications than patients without osteosarcopenia (P < 0.01). In the multivariate analysis, age ≥ 74years old (P = 0.04) and osteosarcopenia (P = 0.04) were independent and significant predictors of in-hospital mortality. Preoperative osteosarcopenia is a risk factor of in-hospital mortality in patients with gastrointestinal perforation after emergency surgery.
