RESUMEN

Colorectal surgery often results in a temporary or permanent ileostomy construction. The general nutritional status and intake of patients with an ileostomy have not received much attention and scientific evidence is lacking. Nutritional complications associated with ileostomy formation and colonic exclusion include fluid (dehydration) and electrolyte abnormalities (mainly hyponatremia), impaired renal function occurring from plasma volume depletion, and reduced energy absorption due to the role of the large bowel in energy assimilation. People with ileostomies frequently avoid specific foods, due to concerns of possible malfunction or food blockages of their stoma, which may produce a negative effect on their overall dietary intake and nutritional status. The present article reviews the existing literature on nutritional considerations for those with an ileostomy and discusses measures to optimize overall nutritional status of this category of patients.

RESUMEN

BACKGROUND/OBJECTIVES: Data on the effect of dietary fat on dumping syndrome (DS) symptoms are limited. The aim of this study was to assess the effect of the addition of fat to a carbohydrate meal on the appearance of DS symptoms and glycemic response, in patients who had undergone gastric surgery. SUBJECTS/METHODS: This was an interventional crossover study. Patients scheduled for gastric surgical procedures related to DS at two surgical units of two public hospitals (General University Hospital of Larissa and General Hospital of Larissa) were considered for study inclusion. Patients presenting symptoms suggestive of diagnosis (n = 12), after the ingestion of a carbohydrate meal, were used as both intervention and control groups. During the intervention process, a fat supplement was added to the carbohydrate meal that was previously used for diagnosis. Glycemic response and the amount and intensity of DS symptoms provoked by the two meals were assessed at both appointments. RESULTS: Blood glucose levels were significantly lower in the group that consumed the added fat meal compared with the group that consumed the carbohydrate meal 60 minutes after ingestion (p = 0.028). Furthermore, a significant reduction was noted in the amount of late dumping symptoms (p = 0.021) and the intensity of both early and late dumping symptoms (p = 0.007 and p = 0.012 respectively), after fat addition.  Conclusions: Incorporating fat into a carbohydrate meal seems to attenuate postprandial blood glucose rises and reduce the amount and intensity of DS symptoms, in patients who had undergone gastric surgery.

RESUMEN

INTRODUCTION: Attendance of patients to the emergency department due to acute large bowel obstruction is a common phenomenon. Most of these patients are elderly, critically ill, and with high comorbidity. The literature suggests that more than 50% of these cases are due to colon cancer. Since this condition is considered to be an emergency, immediate intervention and response is imperative. PURPOSE: The aim of the present study is to present our surgical technique of colostomy formation under local anesthesia in selected critically ill patients, with increased perioperative risk and acute large bowel obstruction. MATERIALS AND METHODS: This is a retrospective study of 24 patients, with obstipation, who underwent emergency colostomy under local anesthesia, during the period from 2014 to 2021. RESULTS: The mean age of the patients was 77 years. The vast majority of patients had an American Society of Anesthesiologists (ASA) score of ≥3 and a Charlson score of ≥7. The most common colostomy was transverse colostomy (21/24 patients). The patients' hospitalization ranged from four to 42 days. Only one patient died. All colostomies functioned properly in the immediate postoperative period. Only one patient required postoperative admission to the ICU. CONCLUSIONS: Colostomy under local anesthesia in critically ill, elderly patients is an alternative option for the treatment of ileus.

RESUMEN

Purpose: Bone mineral density (BMD) was measured in uncomplicated young adult patients with type 1 diabetes mellitus (T1DM) and sex- and age-matched controls, using both dual X-ray absorptiometry (DXA) and quantitative computed tomography (QCT) to investigate their diagnostic ability in detecting abnormal values in these patients. Methods: 118 patients with T1DM (65 females, mean age 30.12 ± 8.78 years) and 94 sex- and age-matched controls were studied. BMD was assessed in all participants by DXA and QCT at lumbar spine (LS). Biochemical markers of bone metabolism were also measured. Results: T1DM was associated with lower BMD at L1-L3 vertebrae measured by both DXA and QCT and lower bone turnover compared to sex- and age-matched controls. In T1DM subjects, QCT detected more patients with abnormal BMD values compared to DXA. BMI and HbA1c levels were the only determinants of BMD. Bone turnover markers were lower in patients with longer duration of diabetes. Conclusion: QCT provides a higher sensitivity compared to DXA in detecting abnormal BMD values in patients with uncomplicated T1DM. In these patients, the diabetes-related decreased BMD may be present early, before it is detected by DXA, the clinical gold standard for BMD measurements, and before the presence of any other diabetes complications, stressing the importance of an early intervention for fracture prevention.

RESUMEN

BACKGROUND: Severe complicated intra-abdominal sepsis (SCIAS) has an increasing incidence with mortality rates over 80% in some settings. Mortality typically results from disruption of the gastrointestinal tract, progressive and self-perpetuating bio-mediator generation, systemic inflammation, and multiple organ failure. A further therapeutic option may be open abdomen (OA) management with negative peritoneal pressure therapy (NPPT) to remove inflammatory ascites and attenuate the systemic damage from SCIAS, although there are definite risks of leaving the abdomen open whenever it might possibly be closed. This potential therapeutic paradigm is the rationale being assessed in the Closed Or Open after Laparotomy (COOL trial) ( https://clinicaltrials.gov/ct2/show/NCT03163095 ). Initially, the COOL trial received Industry sponsorship; however, this funding mandated the use of a specific trademarked and expensive NPPT device in half of the patients allocated to the intervention (open) arm. In August 2022, the 3 M/Acelity Corporation without consultation but within the terms of the contract canceled the financial support of the trial. Although creating financial difficulty, there is now no restriction on specific NPPT devices and removing a cost-prohibitive intervention creates an opportunity to expand the COOL trial to a truly global basis. This document describes the evolution of the COOL trial, with a focus on future opportunities for global growth of the study. METHODS: The COOL trial is the largest prospective randomized controlled trial examining the random allocation of SCIAS patients intra-operatively to either formal closure of the fascia or the use of the OA with an application of an NPPT dressing. Patients are eligible if they have free uncontained intraperitoneal contamination and physiologic derangements exemplified by septic shock OR severely adverse predicted clinical outcomes. The primary outcome is intended to definitively inform global practice by conclusively evaluating 90-day survival. Initial recruitment has been lower than hoped but satisfactory, and the COOL steering committee and trial investigators intend with increased global support to continue enrollment until recruitment ensures a definitive answer. DISCUSSION: OA is mandated in many cases of SCIAS such as the risk of abdominal compartment syndrome associated with closure, or a planned second look as for example part of "damage control"; however, improved source control (locally and systemically) is the most uncertain indication for an OA. The COOL trial seeks to expand potential sites and proceed with the evaluation of NPPT agnostic to device, to properly examine the hypothesis that this treatment attenuates systemic damage and improves survival. This approach will not affect internal validity and should improve the external validity of any observed results of the intervention. TRIAL REGISTRATION: National Institutes of Health ( https://clinicaltrials.gov/ct2/show/NCT03163095 ).

RESUMEN

Inguinal hernias are amongst the most common conditions requiring general surgical intervention. For decades, the preferred approach was the open repair. As laparoscopy became more popular and available and more surgeons became familiarized with this modality, laparoscopic inguinal hernia repair became an alternative. The aim of this study is to assess the effectiveness of laparoscopic inguinal repair, with a focus on bilateral inguinal hernias. Initial reports have shown promising clinical outcomes compared to those of conventional repair of bilateral hernias. However, there are only a few studies concerning laparoscopic repair of bilateral hernias. It is yet to be proven that laparoscopy is the "gold standard" in the treatment of bilateral inguinal hernias. So far, the choice of an inguinal hernia repair technique has been up to each surgeon, depending on their expertise and available resources after taking into consideration each patient's needs.

RESUMEN

Background Incarcerated hernia is a common surgical emergency with considerable morbidity or even mortality. Manual reduction (taxis) and elective surgery could be an alternative management approach. This study examines the role of taxis with the adjuvant use of the visual analogue scale (VAS) score in treating incarcerated hernias and thereby decreasing the emergency surgery rate, especially during the novel coronavirus disease 2019 (COVID-19) pandemic. Methods All adult patients admitted to the emergency department of our hospital with incarcerated hernias of anterior abdominal wall were prospectively submitted to hernia manual reduction. The VAS score was used as an adjuvant tool for monitoring the success of this maneuver. Patients with successful taxis and low VAS score were hospitalized for a 24-hour period of observation. On their discharge, they were scheduled for an elective hernia repair. Patients with unsuccessful taxis or with less than a 50% reduction in VAS score after successful taxis were submitted to emergency surgical repair. Age, sex, type of hernias, time until taxis, VAS scores before and after taxis, length of hospital stay, and adverse events for both groups were recorded. Results Between September 2018 and September 2020, 86 patients with incarcerated hernias were included. The types of hernias were incisional in 8 patients, umbilical in 15 patients, inguinal in 56 patients, and femoral in 7 patients. Taxis was successful in 66% of patients with a mean reduction in VAS score from 83 to 17 mm. Following successful taxis, patients were hospitalized for a 24-hour period of observation. No taxis-related complications were observed. Fifty-two patients were safely discharged from hospital and scheduled for an elective repair during the first month. Thirty-four patients were operated emergently. Five patients had successful taxis but with a reduction of posttaxis VAS score less than 50% (a mean reduction from 86 to 62 mm), while taxis failed in twenty-nine patients. Patients with emergency surgery had longer time until reduction and longer stay of hospitalization. In this group, two patients required admission to the intensive care unit while one patient died. Conclusion In this protocolized approach, taxis is a safe and feasible option for most patients with incarcerated hernias. It should be kept in our armament, especially in times when emergency surgery capabilities are under strain like the ongoing COVID-19 pandemic.

RESUMEN

Bacteria of the human intestinal microflora have a dual role. They promote digestion and are part of a defense mechanism against pathogens. These bacteria could become potential pathogens under certain circumstances. The term "bacterial translocation" describes the passage of bacteria of the gastrointestinal tract through the intestinal mucosa barrier to mesenteric lymph nodes and other organs. In some cases, the passage of bacteria and endotoxins could result in blood stream infections and in multiple organ failure. Open elective abdominal surgery more frequently results in malfunction of the intestinal barrier and subsequent bacterial translocation and blood stream infections than laparoscopic surgery. Postoperative sepsis is a common finding in patients who have undergone non-elective abdominal surgeries, including trauma patients treated with laparotomy. Postoperative sepsis is an emerging issue, as it changes the treatment plan in surgical patients and prolongs hospital stay. The association between bacterial translocation and postoperative sepsis could provide novel treatment options.

RESUMEN

INTRODUCTION: This randomized controlled study aims to investigate the prophylactic effect of tamsulosin on the development of postoperative urinary retention (POUR) in men undergoing elective open inguinal hernia (IH) repair under spinal anesthesia. The study also focused on potentially predisposing factors for POUR. METHODS: 100 eligible patients were randomized into two groups. Patients in the experimental group were given two doses of tamsulosin 0.4 mg orally 24 hours and 6 hours before surgery. In the control group, two doses of placebo were administered, in the same manner as the study group. The following parameters were also recorded: the International Prostate Symptom Score (IPSS) questionnaire scores, the presence of scrotal hernia, operation duration, perioperative administration of IV opioids and/or atropine, postoperative pain, and preoperative anxiety. RESULTS: Overall, the incidence of POUR was 37% (37/100) with no difference between the two groups. Among patients receiving tamsulosin, 39.2% (20/51) developed POUR, compared to 34.7% (17/49) in the control group. Preoperative patients' high anxiety visual analog scale (VAS) score (>51mm) (P=0.007) and the intraoperative use of atropine (P=0.02) were detected as risk factors for POUR. CONCLUSION: This interim analysis of our prospective randomized trial showed no benefit from the prophylactic use of tamsulosin in preventing POUR after IH repair under spinal anesthesia. This type of anesthesia was also correlated with an overall high incidence of POUR. Preoperative anxiety and administration of atropine were identified as statistically significant factors for POUR. In patients with preoperative high anxiety, VAS score a different type of anesthesia may be used.

RESUMEN

INTRODUCTION: Gastrointestinal stromal tumors (GISTs) quite frequently occur synchronously with other malignancies, with most cases being adenocarcinomas. GISTs and liposarcomas are both of mesenchymal origin, and their coexistence is extremely rare. METHODS: We conducted a review of the current literature regarding the synchronous occurrence of GISTs and intra-abdominal liposarcomas. An electronic search of the literature was undertaken using MEDLINE (database provider PubMed). Furthermore, we present the first described case of an 86-year-old male with a GIST and synchronous liposarcoma, both located in the stomach, as well as a 66-year-old male with a gastric GIST and concurrent retroperitoneal liposarcoma. RESULTS: A total of 5 cases of synchronous GIST and intra-abdominal liposarcoma have been reported in the literature to date, with the most recent cases included in the present study. CONCLUSION: Further research is required to explain any possible correlation in the coexistence of these different neoplasms of the same origin. Meanwhile, R0 resection of both tumors remains the treatment of choice.

RESUMEN

OBJECTIVE: To conduct a prospective study of the potential prognostic role of endothelin-1 (ET-1) in a cohort of primary high-grade non-muscle-invasive urothelial bladder cancer patients, who were treated with adjuvant intravesical Bacillus Calmette-Guérin (BCG). MATERIAL AND METHODS: Patients with primary high-grade nonmuscle- invasive urothelial bladder cancer, who received postoperatively induction and maintenance BCG therapy, were prospectively included. Recurrence and progression were histologically proven. Immunohistochemical staining for ET-1 was assessed. Epidemiological, pathological and clinical parameters as well as the expression of ET-1 in tumor specimens were statistically analyzed for recurrence, progression, recurrence-free survival (RFS) and progression-free survival (PFS). RESULTS: ET-1 associates significantly with recurrence (p = 0.000), progression (p = 0.000), RFS (p = 0.000) and PFS (p = 0.000). The patient's age is also significant for recurrence (p = 0.003, OR = 1.273 95% CI: 1.086-1.492) and RFS (p = 0.013). CONCLUSIONS: ET-1 seems to deteriorate prognosis in patients suffering from primary high-grade non-muscle-invasive urothelial bladder cancer, who are treated with adjuvant BCG instillations. Furthermore, the patient's age associates with an increased likelihood for recurrence.

RESUMEN

The potential of apigenin (APG) to enhance cisplatin's (CDDP) chemotherapeutic efficacy was investigated in HepG2, Hep3B, and Huh7 liver cancer cell lines. The presence of 20 µM APG sensitized all cell lines to CDDP treatment (degree of sensitization based on the MTT assay: HepG2>Huh7>Hep3B). As reflected by sister chromatid exchange levels, the degree of genetic instability as well as DNA repair by homologous recombination differed among cell lines. CDDP and 20 µM APG cotreatment exhibited a synergistic genotoxic effect on Hep3B cells and a less than additive effect on HepG2 and Huh7 cells. Cell cycle delays were noticed during the first mitotic division in Hep3B and Huh7 cells and the second mitotic division in HepG2 cells. CDDP and CDDP + APG treatments reduced the clonogenic capacity of all cell lines; however, there was a discordance in drug sensitivity compared with the MMT assay. Furthermore, a senescence-like phenotype was induced, especially in Hep3B and Huh7 cells. Unlike CDDP monotherapy, the combined treatment exhibited a significant anti-invasive and anti-migratory action in all cancer cell lines. The fact that the three liver cancer cell lines responded differently, yet positively, to CDDP + APG cotreatment could be attributed to variations they present in gene expression. Complex mechanisms seem to influence cellular responses and cell fate.

RESUMEN

PURPOSE: The aim of this meta-analysis was to investigate the role of adjuvant chemotherapy (AC) in rectal cancer patients with pathologic complete response (pCR) after neoadjuvant chemoradiotherapy (nCRT) and curative resection. METHODS: This study was completed in accordance to the PRISMA guidelines and the Cochrane Handbook for Systematic Reviews of Interventions. The electronic scholar databases (Medline, Web of Science, Scopus) were screened for eligible articles. The level of evidence (LoE) was assessed using the GRADE methodology. RESULTS: Overall, 23 non-randomized studies and 17,406 patients were included in the present meta-analysis. Pooled comparisons confirmed that AC improved overall survival (HR: 0.68, p=0.0003), but not disease-free (p=0.22) and recurrence-free survival (p=0.39). However, the LoE for all outcomes was characterized as "very low," due to the absence of RCTs. CONCLUSIONS: Considering the study limitations and the lack of randomized studies, further high-quality RCTs are required to confirm the findings of our study.

RESUMEN

BACKGROUND AND AIMS: The effects of ileostomy construction and colonic bypass on the general nutritional status of the patients have not yet received much attention. The aim of the present study was to assess the effect of a diverting ileostomy formation, on the nutritional intake, body composition and nutritional status biochemical markers of patients with a newly formed ileostomy. METHODS: This was an observational study. Patients scheduled for elective rectosigmoid resection at a surgical unit of a public university hospital, were considered for study inclusion. Patients in whom a diverting ileostomy was created were assigned to the ileostomy group (n = 41), and patients who underwent rectosigmoid resection without requiring a diverting ileostomy served as a control group (n = 37). Anthropometric characteristics, body composition, dietary intake and biochemical markers representative of nutritional status were assessed preoperatively and at 40 days postdischarge (NCT02036346). RESULTS: Anthropometric and body composition characteristics (weight, BMI and body fat percentage) significantly declined from 75 to 71.6 kg, 26.9 to 25.6 kg/m2 and 28.6 to 25.6% respectively (p = 0.001 for all) in the ileostomy group, between the preoperative stage and 40 days postdischarge from the hospital. Furthermore, a significant reduction in mean daily energy intake from 1871 to 1713 kcal/day (p = 0.046) was observed in the ileostomy group 40 days after discharge compared to preoperative assessment. No significant changes in the above measured parameters were observed in the non-ileostomy group. CONCLUSION: Diverting ileostomy can have a negative effect on general nutritional status and dietary intake of patients, during the first postoperative period. Nutritional assessment might need to be included in the routine clinical management of this patient category to prevent weight loss and impaired energy intake.

RESUMEN

To investigate the potential prognostic role of NFκB expression in primary high-grade non-muscle-invasive bladder cancer. Patients with primary high-grade non-muscle-invasive bladder cancer who received induction and maintenance BCG therapy were retrospectively included. Recurrence and progression were histologically proven. Intensity and extent of immunochemistry were assessed. The final evaluation of the NFκB staining was done by combining intensity and extent as ΄΄product΄΄ and expressing it as ΄΄low NFκΒ expression΄΄ or ΄΄high NFκB expression΄΄. Epidemiological, pathological, clinical parameters and NFκB expression were statistically analyzed for recurrence (REC), progression (PR), recurrence-free survival (RFS) and progression-free survival (PFS). NFκB is significantly associated with disease progression (p < 0,001 in univariate analysis and p = 0,001, Odds Ratio = 14,484, 95% Confidence Interval = 3187-65,821 in multivariate analysis), but not with recurrence. The median value of NFκB expression as ΄΄product΄΄ is significantly higher for the patients with progression in comparison to patients with recurrence only (p = 0,003) and patients without recurrence or progression (p = 0,001). Patients' age is significantly associated (p = 0,001 in univariate analysis and p = 0,003, Odds Ratio = 1273, 95% Confidence Interval = 1086-1492 in multivariate analysis) with disease recurrence. High NFκB expression in primary high-grade non-muscle-invasive bladder cancer, treated with postoperative intravesical BCG immunotherapy, could represent an unfavorable prognostic factor.

RESUMEN

PURPOSE: To evaluate the effect of hexanic extract of Serenoa repens (HESr) on prostatic inflammation in patients with diagnosed prostatic inflammation. METHODS: Patients with prostatic inflammation histologically confirmed by TRUS prostatic biopsy were randomized either to receive HESr (320 mg/day) or no treatment. A second biopsy was performed 6 months later according to standard clinical practice. Inflammation was assessed by the Irani's score and immunohistochemical staining using the CD3, CD4 and CD8 (for T-leucocytes), CD20 (for B-leucocytes) and CD163 (for macrophages) antibodies. RESULTS: Overall 97 patients were eligible for analysis. In the HESr group the mean inflammation grading and aggressiveness grading score significantly decreased from 1.55 and 1.55 at baseline to 0.79 (p = 0.001) and 0.87 (p = 0.001) at the second biopsy, respectively. In the control group the mean inflammation grading score was 1.44 at first biopsy and 1.23 at the second biopsy. The mean aggressiveness gradings core was 1.09 and 0.89, respectively. No statistical significance was found (p = 0.09 and p = 0.74).The mean decrease in all inflammation scores was statistically higher in the HESr patients compared to controls. The immunohistochemical staining showed a significant change in the expression of the analyzed antibodies for the HESr patients compared to the first biopsy. In the nontreatment group, no significant difference was found at the second biopsy. The change in expression of each antibody in the HESr group was statistical significant compared to control. CONCLUSIONS: HESr seems to reduce prostatic inflammation in terms of histological and immunohistochemical parameters in this specific patients population.

RESUMEN

BACKGROUND: The use of surgical meshes in ventral hernia repair has significantly reduced hernia recurrence rates. However, when placed intraperitoneally prosthetic materials can trigger the development of peritoneal adhesions. The present experimental study evaluated the combined icodextrin 4% and dimetindene maleate treatment in preventing peritoneal adhesion formation to polypropylene and titanium-coated polypropylene meshes. MATERIALS AND METHODS: Sixty female white rabbits were divided into four groups. A 2 × 2 cm piece of mesh was fixed to intact peritoneum in all animals through a midline laparotomy. A lightweight polypropylene mesh was implanted in groups 1 and 2 and a titanium-coated polypropylene mesh in groups 3 and 4. Groups 2 and 4 were treated, intraoperatively, with intravenous dimetindene maleate (0.1 mg/kg) and intraperitoneal solution of icodextrin 4% (20 mL/kg) and for the next 6 d with dimetindene maleate intramuscularly. The observation period lasted 15 d. Adhesion scores, percentage of mesh affected surface, tissue hydroxyproline levels, and tissue histopathology were examined. RESULTS: All animals in group 1 and 57% of animals in group 3 presented postoperative adhesions. The combination of antiadhesives significantly reduced the extent and severity of adhesions as well as the hydroxyproline levels in groups 2 and 4 compared with groups 1 and 3. On microscopic evaluation, animals in group 1 exhibited higher inflammation scores compared with group 2, whereas animals in groups 2 and 4 had better mesotheliazation compared with groups 1 and 3. CONCLUSIONS: The combined administration of icodextrin 4% and dimetindene maleate reduces the extent and severity of adhesions and may be successfully used to prevent adhesion formation after mesh intraperitoneal placement.

RESUMEN

BACKGROUND: Patients with a newly formed ileostomy often develop electrolyte abnormalities and dehydration. OBJECTIVE: The study assessed the prophylactic effect of an isotonic hydration solution on dehydration and electrolyte abnormalities in patients with a newly formed ileostomy. DESIGN: This was a prospective, randomized, controlled trial (NCT02036346). SETTINGS: The study was conducted at a single surgical unit of a public university hospital. PATIENTS: Patients scheduled for elective rectosigmoid resection were considered for study inclusion. INTERVENTION: Patients in whom a diverting ileostomy was created were randomly assigned to the intervention group (n = 39), which received an oral isotonic glucose-sodium hydration solution for 40 days postdischarge and the control group (n = 41) which did not receive an intervention. The 2 groups were compared with a group of patients who underwent rectosigmoid resection without diverting ileostomy (n = 37). MAIN OUTCOME MEASURES: Serum electrolyte and renal function markers were assessed preoperatively and at 20 and 40 days postdischarge. RESULTS: At 20 days postdischarge, the serum sodium of the control group appeared lower than the serum sodium of the intervention group and the nonileostomy group (p = 0.007). At the same time point, urea and creatinine levels of the control group were higher than the urea and creatinine levels of the other 2 groups (p = 0.01 and p = 0.02). At 40 days postdischarge, mean sodium and renal function markers improved in the control group, but sodium and creatinine continued to differ in comparison with the intervention and nonileostomy groups (p = 0.01 and p = 0.04). The readmission rate for fluid and electrolyte abnormalities was higher in the control group (24%) than in the other 2 groups, where no rehospitalization for such a reason was required (p = 0.001). LIMITATIONS: The study was limited by its single-center design. CONCLUSION: An oral isotonic drink postdischarge can have a prophylactic effect on patients with a newly formed ileostomy, preventing readmission for fluid and electrolyte abnormalities.

RESUMEN

Uterine cervix carcinoids are distinct neuroendocrine cervical tumors, representing a comparatively small percentage of them. These well-differentiated neoplasms are far less prevalent than small- and large-cell carcinomas, characterized by a more favorable biological course. We report a case of a 43-year-old woman with a nonmetastatic cervical carcinoid, managed with radical hysterectomy. She still remains free of disease. Scant reports in the literature prohibit any reliable prediction of cervical carcinoid prognosis. Thus, prompt identification of the disease and subsequent therapeutic intervention could alter the final outcome.
