Impact of pandemic and socioeconomic influences on decision-making for emergency ostomy procedures: Key factors affecting hospital visit decisions.

Emergency surgeries are linked with increased morbidity and reduced life expectancy, often associated with low socioeconomic status, limited access to healthcare, and delayed hospital admissions. While the influence of socioeconomic status on elective surgery outcomes is well-established, its impact on emergency surgeries, including ostomy creation and closure, is less clear. This study aimed to explore how the pandemic and socioeconomic status affect emergency ostomy procedures, seeking to determine which has a greater effect. It emphasizes the importance of considering socioeconomic factors in patient care pathways for ostomy procedures. A total of 542 patients who underwent emergency ostomy formation between 2016 and 2022 were retrospectively analyzed and divided into pre-pandemic and pandemic periods. The pre-pandemic and pandemic periods were compared between themselves and against each other. Demographic data (age and sex), comorbidities, socioeconomic status, etiology of the primary disease, type of surgery, stoma type, length of hospital stay, ostomy closure time, and postoperative complications were retrospectively analyzed for all patients. In total, 290 (53%) patients underwent surgery during the pandemic period, whereas 252 (47%) underwent surgery during the pre-pandemic period. Emergency surgery was performed for malignancy in 366 (67%) patients. The number of days patients underwent ostomy closure was significantly higher in the low-income group (P = .038, 95% CI: 293,2, 386-945). The risk of failure of stoma closure was 3-fold (95% CI: 1.8-5.2) in patients with metastasis. The risk of mortality was 12.4-fold (95% CI: 6.5-23.7) when there was failure of stoma closure. When compared to pandemic period, the mortality risk was 6.3-fold (95% CI: 3.9-10.2) in pre-pandemic period. Pandemic patients had a shorter hospital stay than before the pandemic (P = .044). A high socioeconomic status was significantly associated with early hospital admission for ostomy closure, and lower probability of mortality. More metastases and perforations were observed during the pandemic period and mortality was increased during pandemic and in patients without ostomy closure. The socioeconomic status lost its effect in cases of emergency ostomy creation and had no impact on length of hospital stay in either the pre-pandemic or pandemic period.

Effects of hyaluronic acid and chondroitin sulfate on acute radiation proctitis in rats.

BACKGROUND: This study was designed to investigate the prophylactic and therapeutic effects of hyaluronic acid and chondroitin sulfate combination (HA/CS) on a model of acute radiation proctitis. METHODS: Rats were divided into five groups: SHAM; irradiation (IR) + saline (1 mL for 5th and 10th day); IR + HA/CS (1 mL for 5th and 10th day). A single fraction of 17.5 Gy was delivered to each rat. HA/CS was administered rectally each day after irradiation. Each rat was observed daily for signs of proctitis. Irradiated rats were euthanized on days 5 and 10. The mucosal changes were evaluated macroscopically and pathologically. RESULTS: According to the clinical findings, five rats in the irradiation + saline group showed grade 3-4 symptoms on the 10th day. No significant difference in the macroscopic finding scores on the 5th day was observed between the irradiation + saline and irradiation + HA/CS groups. In the pathological examination, radiation-induced mucosal damage was the most prominent finding 10 days after irradiation in saline-treated rats. On the 10th day, the irradiation + HA/CS group showed mild inflammation and slight crypt changes, which corresponded to grade 1-2 pathological findings. CONCLUSION: We think that HA/CS used in radiation cystitis can be beneficial for radiation proctitis.

Functional outcomes of intersphincteric resection in low rectal tumors.

Objectives: Currently, sphincter-saving procedures are increasingly performed in the treatment of low rectal cancers. This study aimed to evaluate the outcomes of patients who underwent intersphincteric resection. Material and Methods: This was a single-center, retrospective, cross-sectional study. We evaluated the electronic data files of 29 patients who had intersphincteric resections at our institute between 2008 and 2018. Bowel function outcomes were assessed prospectively using Wexner incontinence score. Histopathological, surgical and functional outcomes were analyzed. Results: Mean age of nine female and 20 male patients included in the study was 55.8 ± 12.8 (30-76) years. A tumor-free surgical margin was achieved in all patients. Anastomotic leakage was detected in two patients. Mean Wexner incontinence score of 20 patients who still had functional anastomosis was 8.35, whereas 65% of the patients (n= 13) had a good continence status. There was no relationship between the continence status and sex, tumor distance from anal verge, T stage, distal surgical margin, and lymph node involvement. Twenty-one patients underwent primary coloanal anastomosis and eight patients underwent two-stage coloanal anastomosis. Conclusion: In the treatment of distal rectal cancer, adequate oncological surgery and relatively acceptable functional outcomes can be obtained with intersphincteric resection technique in suitable patients.

Effect of interval between neoadjuvant chemoradiotherapy and surgery on disease recurrence and survival in rectal cancer: long-term results of a randomized clinical trial.

BACKGROUND: The optimal timing of surgery following chemoradiotherapy (CRT) is controversial. This trial aimed to assess disease recurrence and survival rates between patients with locally advanced rectal adenocarcinoma (LARC) who underwent total mesorectal excision (TME) after a waiting interval of 8 weeks or less (classic interval; CI) versus more than 8 weeks (long interval; LI) following preoperative CRT. METHODS: This was a phase III, single-centre, randomized clinical trial. Patients with LARC situated within 12 cm of the anal verge (T3-T4 or N+ disease) were randomized to undergo TME within or after 8 weeks after CRT. RESULTS: Between January 2006 and January 2017, 350 patients were randomized, 175 to each group. As of February 2022, the median follow-up time was 80 (6-174) months. Among the 322 included patients (CI, 159; LI, 163) the cumulative incidence of locoregional recurrence at 5 years was 10.1 per cent in the CI group and 6.9 per cent in the LI group (P = 0.143). The cumulative incidence of distant metastasis at 5 years was 30.8 per cent in the CI group and 18.6 per cent in the LI group (sub-HR = 1.78; 95 per cent c.i. 1.14 to 2.78, P = 0.010). The disease-free survival (DFS) in each group was 59.7 and 69.9 per cent respectively (P = 0.157), and overall survival (OS) rates at 5 years were 73.6 versus 77.9 per cent (P = 0.476). CONCLUSION: Incidence of distant metastasis decreased with an interval between CRT and surgery exceeding 8 weeks, but this did not impact on DFS or OS. REGISTRATION NUMBER: NCT03287843 (http://www.clinicaltrials.gov).

Fall of another myth for colon cancer: Duration of symptoms does not differ between right- or left-sided colon cancers.

BACKGROUND/AIMS: Patients with colorectal cancer continue to present with relatively advanced tumors that are associated with poor oncological outcomes. The aim of the present study was to assess the association between localization, symptom duration, and tumor stage. MATERIALS AND METHODS: A prospective, multicenter cohort study was conducted on patients newly diagnosed with a histologically proven colorectal adenocarcinoma. Standardized questionnaire-interviews were performed. Data were collected on principal presenting symptoms, duration of symptoms (time to first presentation to a doctor and time to diagnosis) and treatment, diagnostic procedures, tumor site, and stage of the tumor (tumor, node, and metastasis (TNM)). RESULTS: A total of 1795 patients with colorectal cancer were interviewed (mean age: 60.76±13.50 years, male patients: 1057, patients aged >50 years: 1444, colon/rectal cancer: 899/850, right side/left side: 383/1250, stage 0-1-2/stage 3-4: 746/923). No statistically significant correlations were found between duration of symptoms and either tumor site or stage. Principal presenting symptoms were significantly associated with left colon cancer. Patients who had "anemia," "change in bowel habits," "anal pruritus or discharge," "weight loss," and "tumor in right colon" had a significantly longer symptom time. CONCLUSION: Symptom duration is not associated with localization, nor is the tumor stage. Diagnosis of colorectal cancer at an earlier stage may be best achieved by screening of the population.

The effects of chemoradiotherapy on recurrence and survival in locally advanced rectal cancers with curative total mesorectal excision: a prospective, nonrandomized study.

BACKGROUND: There are only two prospective, randomized studies comparing preoperative long-term chemoradiotherapy and postoperative chemoradiotherapy in locally advanced rectal cancer (LARC); however, conflicting results in terms of locoregional recurrence (LR) and survival rates have been reported. This prospective study aims to compare the effects of preoperative versus postoperative chemoradiotherapy on recurrence and survival rates in LARC patients. METHODS: From January 2003 to January 2016, a total of 336 eligible patients who were clinically diagnosed with LARC (T3-T4 tm or node-positive disease) were prospectively assigned into preoperative chemoradiotherapy (n = 177) and postoperative chemoradiotherapy (n = 159) groups. The preoperative treatment consisted of 50.4 Gy total dose of radiotherapy (delivered in fractions of 1.8 Gy) and concomitant two cycles chemotherapy of 5-fluorouracil and leucovorin. The patients in the preoperative group underwent curative total mesorectal excision (TME) following long-term chemoradiotherapy. Surgery was performed 8 (range 4-12) median weeks after the completion of the chemoradiotherapy. Similar protocol was administered to the postoperative group 4 weeks after the operation. Four cycles of adjuvant chemotherapy were added to the groups. The primary end points were locoregional recurrences and 5-year cancer-specific, overall, and disease-free survivals. RESULTS: The mean follow-up period was 60.4 (range 12 to 168) months. Five-year cumulative incidence of locoregional recurrence (LR) was 7.4% in the preoperative group and 13.4% in the postoperative group (p = 0.021). Five-year cancer-specific survival (CSS) was 87.5% in the preoperative group and 80% in the postoperative group (p = 0.022). Overall survival (OS) was 79.8 versus 74.7% (p = 0.064), disease-free survival (DFS) was 75.2 versus 64.8% (p = 0.062), and severe late toxicity was 7.4 versus 13.2% (p = 0.002), respectively. The rate of patient compliance was higher in the preoperative group (p < 0.001). CONCLUSIONS: Preoperative chemoradiotherapy, as compared with postoperative chemoradiotherapy, significantly improved local control, patient compliance, CSS, and late toxicity and suggested a trend toward improved overall and disease-free survival.

Prognostic factors in peptic ulcer perforations: a retrospective 14-year study.

Regarding the complications of peptic ulcer, a perforation remains the most important fatal complication. The aim of our retrospective study was to determine relations between postoperative morbidity and comorbid disease or perioperative risk factors in perforated peptic ulcer. In total, 239 patients who underwent emergency surgery for perforated peptic ulcer in Ege University General Surgery Department, between June 1999 and May 2013 were included in this study. The clinical data concerning the patient characteristics, operative methods, and complications were collected retrospectively. One hundred seventy-five of the 239 patients were male (73.2%) and 64 were female (26.8%). Mean American Society of Anesthesiologists (ASA) score was 1 in the patients without morbidity, but mean ASA score was 3 in the morbidity and mortality groups. Primary suture and omentoplasty was the selected procedure in 228 of the patients. Eleven patients underwent resection. In total, 105 patients (43.9%) had comorbidities. Thirty-seven patients (67.3%) in the morbidity group had comorbid diseases. Thirteen (92.9%) patients in the mortality group had comorbid diseases. Perforation as a complication of peptic ulcer disease still remains among the frequent indications of urgent abdominal surgery. Among the analyzed parameters, age, ASA score, and having comorbid disease were found to have an effect on both mortality and morbidity. The controversial subject in the present study is regarding the duration of symptoms. The duration of symptoms had no effect on mortality nor morbidity in our study.

A rare cause of colonic obstruction "colonic intussusception": report of two cases.

Colocolic intussusceptions are rare clinical entities in adults and almost always caused by a leading lesion which often warrants resection. Mostly being malignant, the leading lesions are rarely benign lesions where intraluminal lipomas are the most frequent among them. Most adult intussusceptions require surgical resection owing to two major reasons: common presence of a leading lesion and significantly high risk of malignancy-reaching as high as 65% regardless of the anatomic site-of the leading lesion. Resection of the affected segment is usually the treatment of choice, since preoperative diagnosis of the lesion is usually ineffective and most leading lesions are malignant. This paper represents two cases of adult colocolic intussusception caused by intraluminal lipomas with a brief review of the literature.

Should subtotal thyroidectomy be abandoned in multinodular goiter patients from endemic regions requiring surgery?

The most convenient surgical procedure for benign thyroid diseases is still controversial. The aim of this study is to determine the recurrence rate and risk factors for recurrence after different thyroidectomy procedures in multinodular goiter patients. Patients were separated into two groups according to the detection of a recurrent nodule or not after thyroidectomy. Of the 748 patients, 216 (29%) had recurrence, while 532 had no recurrent nodule. The difference between surgical procedures described as subtotal (ST), near total (NT) and total thyroidectomy (TT) was statistically significant. Transient hypoparathyroidism was significantly higher in NT and TT, when compared to ST patients (P < 0.05). Young age, bilateral multinodular goiter and insufficient surgery are risk factors affecting recurrence for benign nodular thyroid disease. Currently, subtotal procedures should be discontinued and total or near total procedures should be preferred. Meanwhile, the probability of a higher risk of hypoparathyroidism should be kept in mind.

Totally Curative Surgical Resection of Retrorectal Tumors.

BACKGROUND/AIMS: Retrorectal (also known as presacral) tumor (RT) is a rare disease of retrorectal space. There is no large numbered case series in the literature. Well documented small numbered case series will help to establish meta-analysis and surgical decision making. METHODOLOGY: Between 2000 and 2014 medical records of patients with diagnosis of RT at two institutions were reviewed. Clinical features, diagnostic studies, type of surgery, surgical findings, surgical technique, and histopathology of the tumor, morbidity and survival are examined based on data registry. RESULTS: During 14 years period of time, total of 12 patients operated with diagnosis of RT were retrieved to this study. There were five men and seven women. The median age at the time of diagnosis was 43 (27-56) years. The most frequent findings were pain and palpable mass. There were five anterior, four posterior and three anteroposterior approaches for surgery. There is no recurrence or disease related mortality observed after median of 7 years (1-14). CONCLUSION: The primary and only satisfactory treatment is surgery for RTs. Prognosis is directly related primary local control with complete excision, which is often difficult to achieve for malignant lesions.

A rare cause of mechanical obstruction: Intestinal myeloid sarcoma.

Myeloid sarcoma is a rare aggressive tumour that originates from immature extramedullary myeloid cells. It can be seen as a relapse in patients with acute myeloid leukaemia. Sometimes it can be seen in the form of a solid tumour without any evidence of leukaemia. A case of a 44-year-old male patient who was admitted with symptoms and signs of mechanical intestinal bowel obstruction was operated on. The operation findings showed small bowel obstruction due to a mass. The mass was then resected with end-to-end intestinal anastomosis. The resected mass pathology results were consistent with myeloid sarcoma. The post-operative period was uneventful and adjuvant therapy was applied. In this case report we aimed to evaluate the clinical signs and treatment modalities of small intestinal myeloid sarcoma.

Recurrent pilonidal sinus: lay open or flap closure, does it differ?

Treatment options of pilonidal sinus, which has high recurrence rates, is still controversial. In this study, we aimed to analyze for possible factors affecting recurrence. Forty-one patients with recurrent pilonidal sinus were included in this study. Of them, 33 were male and 9 were female (mean age, 24.9 years; age range, 16-42). Factors (i.e., risk factors) were detected in 32 patients. Excision-secondary healing and lay open was performed on 30 of the patients admitted with recurrence. Excision and flap closure was applied on 11 patients. Our recurrence rate was 9.7%. The recurrence rate of our study is compatible with the literature. Comparative studies are needed to determine the appropriate method to decrease recurrence rate.

Complicated Meckel's diverticulum and therapeutic management.

OBJECTIVE: This study aimed to investigate the treatment options and compare patient management with the literature for patients operated on for an acute abdomen who had complications due to inflammation of the Meckel's diverticulum at our clinics. MATERIAL AND METHODS: This study retrospectively evaluated 14 patients who had been operated on for acute abdomen and had been diagnosed with Meckel's diverticulitis (MD) in Ege University Medical Faculty Department of General Surgery, between October 2007 and October 2012. RESULTS: Fourteen patients with a diagnosis of Meckel's diverticulitis (MD) were retrospectively analyzed. Radiologically, the abdominal computer tomography showed pathologies compatible with mechanical intestinal obstruction, Meckel's diverticulitis and peridiverticular abscess, as well as detection of free air within the abdomen on direct abdominal X-ray. Among patients diagnosed with complicated Meckel's diverticuli (obstruction, diverticulitis, perforation) 10 patients had partial small bowel resection and end-to-end anastomosis (71.5%), three patients underwent diverticulum excision (21.4%), and one patient underwent right hemicolectomy+ileotransversostomy (7.1%). CONCLUSION: Meckel's diverticulum is a vestigial remnant of an omphalomesenteric channel in the small bowel. It is a real congenital diverticular abnormality that contains all three layers of the small bowel. Surgical excision should be performed if Meckel's diverticulum is detected in order to avoid incidental complications such as ulceration, bleeding, bowel obstruction, diverticulitis or perforation. Meckel's diverticulitis does not have specific clinical and radiological findings. Delayed diagnosis can lead to lethal septic complications. Complications associated with Meckel's diverticulitis, especially if a definite diagnosis is not made during the preoperative period, should be considered in the differential diagnosis. In the presence of a complicated diverticulum the appropriate treatment should be emergent surgical intervention.

Spontaneous intestinal intramural hematoma: What to do and not to do.

OBJECTIVE: Spontaneous intestinal intramural hematoma is a rare complication of anticoagulant treatment. In this study, we retrospectively evaluated 14 patients with the diagnosis of intramural hematoma of the small intestine who were followed-up and treated in our clinic, and we aimed to determine current approaches in the diagnosis and treatment of intramural hematoma. MATERIAL AND METHODS: Between February 2010-October 2012, 14 patients diagnosed with small intestinal intramural hematoma were retrospectively analyzed. Nine patients were followed due to clinical findings and 5 patients underwent operation with a histopathological diagnosis of intramural hematoma. RESULTS: Abdominal computed tomography demonstrated ileal and jejunal wall thickening in 10 patients, while findings were consistent with mesenteric vascular disease in four. Five patients were operated due to mechanical bowel obstruction and acute abdomen. The other 9 patients were followed up with medical treatment and 8 of these patients were already using warfarin due to cardiac bypass and valve replacement. CONCLUSION: Spontaneous intestinal intramural hematoma is a rare cause of small bowel obstruction due to intramural hematoma, which is encountered even more rarely. An intramural hematoma should be considered among differential diagnosis of patients who present with abdominal pain and symptoms of obstruction with a history of anticoagulant drug use and elevated International Normalized Ratio (INR) levels. Early diagnosis and medical follow-up can provide a good response to treatment in the majority of patients without requiring surgery.
