RESUMEN
PURPOSE: A wide variety of methods has been proposed for treating hemorrhoidal disease. The aim of the study is to assess the safety and effectiveness of hemorrhoidal artery ligation with rectoanal repair (HAL-RAR). METHODS: Retrospective study from January 2010 to November 2019 of patients who underwent HAL-RAR for grade II, resistant to conservative treatment, and grades III and IV hemorrhoidal disease. Demographics, degree of disease, hospital stay, postoperative pain, complications, and recurrence were recorded. Patients were followed up at postoperative days 1 and 8 and at 1, 6, and 12 months. RESULTS: A total of 105 patients (60 men, 45 women) underwent HAL-RAR. Median age was 49 (range, 20-86) years. Two patients with hemorrhoidal thrombosis underwent emergent excision of the hemorrhoid. Median length of hospital stay was 2 (range, 1-13) days. Patients reported median visual analog scale pain score 3 (range, 1-5) on the 1st postoperative day. At 1 month, no patient reported pain, 84.76% of patients confirmed complete resolution of symptoms, while complication rate was 7.61%: 2 patients presented urinary retention, 3 dyschezia, 2 bleeding, and 1 hemorrhoidal necrosis. At 6 months, 2 patients presented mild symptoms and 7 recurrence. At 12 months, 92.4% of patients experienced complete resolution of symptoms, 2 patients intermittent bleeding, and 2 recurrence. Overall recurrence and re-intervention rate were 8.57% rate and 10.5%, respectively. CONCLUSION: HAL-RAR is a safe and effective minimal invasive operative technique related to a high percentage of success, low complication, and recurrence rates. Long-term follow-up is lacking and would better establish the results of this technique. TRIAL REGISTRATION: Trial registration number NCT04778124 Date of registration 26/02/2021 "retrospectively registered".

CONTEXT: Posterior tibial nerve stimulation is a new second-line treatment for refractory fecal incontinence. OBJECTIVE: To assess the efficacy of bilateral transcutaneous posterior tibial nerve stimulation (BTPTNS) for treatment of fecal incontinence in Japanese patients and its impact on quality of life. DESIGN: A prospective observational-interventional study was conducted from May 2015 to June 2017 in patients with fecal incontinence in whom conservative treatment had failed. All patients received a 30-minute session of stimulation twice weekly for 6 consecutive weeks. Evaluation at baseline and at 6 weeks involved the Wexner score, Fecal Incontinence Quality of Life (FIQL) questionnaire, and anal manometry. Patients recorded episodes of incontinence in a weekly diary. MAIN OUTCOME MEASURES: Reduction of 50% or greater in incontinence episodes, decreased Wexner score, and improved FIQL scores. RESULTS: Twenty-two patients with a median age of 64.1 years (range, 26-81 years) and men:women ratio of 9:13 completed BTPTNS. Mean episodes of fecal incontinence were significantly reduced from 4.7 to 1.5 (p < 0.05). An improvement of 50% or better in episodes of fecal incontinence was achieved in 77.2% of patients. The median Wexner score significantly decreased from 10.2 to 6.9 (p < 0.05). The median FIQL score improved from 2.7 to 3.1 (p = 0.06), and significant improvement was seen in the embarrassment domain (2.2 vs 2.8, p < 0.05). Resting and squeezing anal pressures revealed no significant changes. CONCLUSION: Our findings suggest that BTPTNS is safe and well tolerated and may improve symptoms of fecal incontinence. This technique offers an additional noninvasive, less expensive form of treatment.

Generalized pustular psoriasis appears as an uncommon variant form of psoriasis consisting of widespread pustules on an erythematous background (von Zumbusch). A 39-year-old male patient with a history of plaque psoriasis since the age of 9 who had an acute relapse of generalized pustular psoriasis 12 days following a successful renal transplantation is presented. Despite administered immunosuppression for transplantation, the addition of cyclosporine and methotrexate did not reverse the ongoing process of disease and the patient died on the 57th posttransplant day due to multiorgan failure subsequent to severe bone marrow suppression.

Cholelithiasis is the most common cause of acute pancreatitis, accounting 35%-60% of cases. Around 15%-20% of patients suffer a severe attack with high morbidity and mortality rates. As far as treatment is concerned, the optimum method of late management of patients with severe acute biliary pancreatitis is still contentious and the main question is over the correct timing of every intervention. Patients after recovering from an acute episode of severe biliary pancreatitis can be offered alternative options in their management, including cholecystectomy, endoscopic retrograde cholangiopancreatography (ERCP) and sphincterotomy, or no definitive treatment. Delaying cholecystectomy until after resolution of the inflammatory process, usually not earlier than 6 wk after onset of acute pancreatitis, seems to be a safe policy. ERCP and sphincterotomy on index admission prevent recurrent episodes of pancreatitis until cholecystectomy is performed, but if used for definitive treatment, they can be a valuable tool for patients unfit for surgery. Some patients who survive severe biliary pancreatitis may develop pseudocysts or walled-off necrosis. Management of pseudocysts with minimally invasive techniques, if not therapeutic, can be used as a bridge to definitive operative treatment, which includes delayed cholecystectomy and concurrent pseudocyst drainage in some patients. A management algorithm has been developed for patients surviving severe biliary pancreatitis according to the currently published data in the literature.

Thirty-six randomized controlled trials and two meta-analyses were reviewed. With respect to adult patients undergoing first orthotopic liver transplantation (OLT), steroid replacement resulted in fewer cases of overall acute rejection in the corticosteroid free-immunosuppression arm. Initial steroid administration for two weeks and early tacrolimus monotherapy is a feasible immunosuppression regimen without steroid replacement, although further investigations are needed in view of chronic rejections. No significant differences were noted between the treatment groups in terms of patient and graft survival independently of steroid replacement. Renal insufficiency, de novo hypertension, neurological disorders and infectious complications did not differ significantly among steroid and steroid-free groups. Diabetes mellitus, cholesterol levels and cytomegalovirus infection are more frequent in patients within the steroid group. With respect to diabetes mellitus and hypercholesterolemia, the difference was independent of steroid replacement. In relation to transplanted hepatitis C virus patients, mycophenolate mofetil does not appear to have a significant antiviral effect despite early reports. Male gender of donors and recipients, living donors, cold ischemia times, acute rejection, and early histological recurrence were related to the development of advanced hepatitis. There is sufficient scientific clinical evidence advocating avoidance of the ab initio use of steroids in OLT.

To examine, if case series considered together with observational studies tend to produce similar results as randomized-controlled trials (RCTs), on recurrent hernia repair. A systematic literature review and meta-analysis between 1990 and 2013 revealed 46 nonrandomized studies (NRCTs) and 5 RCTs including 25,730 patients. A direct comparison of the summary estimates between RCTs and NRCTs is presented. Outcomes, within or across studies, were compared. Comparisons of all outcomes in NRCTs and RCTs failed to show statistical significance. Prospective/retrospective cohort studies, case series, and RCTs did not differ significantly in their estimates. Adjusted testing for metaregression disclosed that rerecurrence among NRCTs was independent of the study design. The number of included patients and study setting were independent predictors of outcome. Our proposed methodology for a systematic review could potentially give answers where level I evidence is missing or could be a tool for optimization of a RCT design.

This pilot study aimed to determine the feasibility of serum neurotensin/IL-8 values being used as a screening tool for colorectal cancer. Fifty-six patients and 15 healthy controls were assigned to seven groups according to their disease entity based on theater records and histology report. Blood samples for neurotensin and IL-8 were measured using an enzyme-linked immunosorbent assay. There were no differences in the clinical and biochemical parameters of patients and controls. Group (p=0.003) and age (p=0.059, marginally significant) were independent predictors of neurotensin plasma values. Neurotensin (p=0.004) and IL-8 (p=0.029) differed between healthy and colorectal cancer patients. Neurotensin values differentiate the control group from all remaining groups. The value of plasma neurotensin ≤ 54.47 pg/ml at enrollment selected by receiver operating characteristic (ROC) curves demonstrated a sensitivity of 77 %, specificity of 90 %, and an estimate of area under ROC curve (accuracy) of 85 % in predicting colorectal cancer. At enrollment, the value of plasma IL-8 ≥ 8.83 pg/ml had a sensitivity of 85 %, specificity 80 %, and an estimate of area under ROC curve (accuracy) of 81 % in predicting colorectal cancer. IL-8 should be used complementary to neurotensin due to its lower specificity. None of the colorectal cancer patients displayed a combination of high neurotensin and low IL-8 values (beyond cutoffs). It seems that a blood neurotensin/IL-8 system may be used as a screening tool for colorectal cancer, but much has to be done before it is validated in larger-scale prospective studies.

BACKGROUND: The aim of this study is to evaluate the most cost-effective treatment strategy using preperitoneal mesh for patients with recurrent inguinal hernia. Currently, the issue of cost-effectiveness is entirely unresolved. METHODS: A decision analysis was carried out based on the results of a systematic literature review of articles concerning recurrent inguinal hernia repair that were published between 1979 and 2011. A virtual cohort was programmed to undergo three different treatment procedures: (1) laparoscopic totally extraperitoneal hernia repair (TEP), (2) open preperitoneal mesh repair according to Stoppa, and (3) open preperitoneal mesh repair according to Nyhus. We carried out a base-case analysis and varied all variables over a broad range of reasonable hypotheses in multiple one-way and two-way sensitivity analyses. RESULTS: The average cost-effectiveness ratio of Nyhus, Stoppa, and TEP per quality-adjusted life year was US $ ($)1,942, $1,948, and $2,011, respectively. In terms of the incremental cost-effectiveness ratio (ICER), Stoppa was dominated. The choice between TEP or Nyhus procedure depends on the combination of a specific center's rates of recurrence and morbidity as disclosed by three-way sensitivity analysis. CONCLUSIONS: Nyhus and TEP repairs are possible optimal choices depending primarily on the institution's rates of recurrence and morbidity. Based on our net benefit-related decision analysis, a hypothetical "fixed budget trade-off" suggests potential annual incremental health system cost savings of $200,000 attained by shifting care for 1,000 patients from TEP to Nyhus repair (depending on clinical end-points, which is a decisive factor).

BACKGROUND/AIMS: Evidence exists to support both surgical and nonoperative observational approaches to the management of patients with distal rectal cancer who achieve a complete response following neoadjuvant chemoradiotherapy (CRT). This article summarizes findings from key studies on management strategies for complete pathologic and clinical responders after neoadjuvant CRT for rectal cancer. METHODS: A comprehensive literature review was undertaken comparing complete responders to neoadjuvant CRT who underwent surgical procedures or nonoperative observation. RESULTS: The sensitivity and specificity of clinical assessment tools following neoadjuvant CRT are generally low. Endoscopic ultrasound and MRI are widely used for rectal cancer staging; PET/CT is applied for detecting residual cancer, although limitations exist in assessing mesorectal disease. In patients with rectal cancer who receive neoadjuvant CRT, rates of complete pathologic response vary from 5 to 44%. Rates of nodal disease in patients with complete pathologic response vary from 0 to 15%. In patients with stage 0 rectal cancer, excellent long-term oncologic results have been reported for both surgical resection and nonoperative observation; therefore, some authors consider that surgical resection may result in unnecessary morbidity. Whereas neoadjuvant CRT followed by total mesorectal excision (TME) reduces local recurrence and improves 5-year survival, TME is associated with significant morbidity and suboptimal functional results. CONCLUSION: Informed consent in patients with distal rectal cancer who achieve a complete response to neoadjuvant CRT must address both the potential risks of recurrence following nonoperative observation and the increased risks of postoperative morbidity and compromised function following extirpative surgery.

The objective of this study was to establish a prediction model of lymph node status in T1b esophageal carcinoma and define the best squamous and adenocarcinoma predictors. The literature lacks a satisfactory level of evidence of T1b esophageal cancer management. We performed an analysis pooling the effects of outcomes of 2098 patients enrolled into 37 retrospective studies using "neural networks" as data mining techniques. The percentages for lymph node, lymphatic (L+), and vascular (V+) invasion in Sm1 esophageal cancers were 24, 46, and 20 per cent, respectively. The same parameters apply to Sm2 with 34, 63, and 38 per cent as opposed to Sm3 with 51, 69, and 47 per cent. The respective number of patients with well, moderate, and poor histologic differentiation totaled 267, 752, and 582. The rank order of the predictors of lymph node positivity was, respectively: Grade III, (L+), (V+), Sm3 invasion, Sm2 invasion, and Sm1 invasion. Histologic-type squamous and adenocarcinoma (ADC/SCC) was not included in the model. The best predictors for SCC lymph node positivity were sm3 invasion and (V+). As concerns ADC, the most important predictor was (L+). Submucosal esophageal cancer should be managed with surgical resection. However, this is subject to the histologic type and presence of specific predictors that could well alter the perspective of multimodality management.

BACKGROUND: The purpose of this study was to identify which age-related groups of hemodynamically stable blunt trauma patients will present a positive cost-to-benefit ratio, in regard to the screening of incidental findings on Focused Assessment with Sonography for Trauma (FAST). METHODS: We conducted a prospective study using retrospective data taken from the trauma registry of 6,041 consecutive hemodynamically stable blunt trauma patients who underwent FAST at our Level I urban trauma hospital during the year 2009. A receiver operating characteristic curve was used to determine whether age level is useful in detecting organ-/system-specific incidental findings in trauma patients undergoing FAST and to establish the required diagnostic cutoff value of this selected test. A cost-benefit analysis was then performed for the age-specific cutoff values of each organ/system evaluated by FAST. RESULTS: We found 522 incidental findings in 468 patients (7.8%). Further diagnostic workup was instructed in 35% (168 of 468) of patients with incidental findings. The cost-benefit analysis for the age-specific cutoff values found in the receiver operating characteristic curve analysis showed that the project of screening for incidental findings on FAST was viable only when the ultrasound operator additionally searches the liver/biliary tree (≥43 years) and the kidneys (≥56 years). CONCLUSIONS: A systematic examination of the liver and biliary tree and both kidneys of specific age groups during FAST screening of hemodynamically stable blunt trauma patients may disclose a potentially unknown pathology with a positive cost-to-benefit ratio.

BACKGROUND: The objective of this study was to examine the outcomes of comparisons between laparoscopic and open mesh repairs in the setting of recurrent inguinal hernia. METHODS: The electronic databases MEDLINE, Embase, Pubmed, and the Cochrane Library were used to search for articles from 1990 to 2008. The present meta-analysis pooled the effects of outcomes of a total of 1,542 patients enrolled into 5 randomized controlled trials and 7 comparative studies, using classic and modern meta-analytic methods. RESULTS: Significantly fewer cases of hematoma/seroma formation were observed in the laparoscopic group in comparison with the Lichtenstein group (odds ratio, .38; .15-.96; P = .04). A matter of great importance is the higher relative risk of overall recurrence in the transabdominal preperitoneal group compared with the totally extraperitoneal group (relative risk, 3.25; 1.32-7.9; P = .01). CONCLUSIONS: Laparoscopic versus open mesh repair for recurrent inguinal hernia was equivalent in most of the analyzed outcomes.

BACKGROUND: The objective of this study was to examine the impact of self-expanding stents versus locoregional treatment modalities in the setting of esophageal cancer palliation. METHODS: The present meta-analysis pooled the effects of outcomes of 1,027 patients enrolled in 16 randomized controlled trials. RESULTS: The meta-analysis revealed an advantage to the use of stents compared to locoregional modality treatments with respect to the number of patients requiring reinterventions, although the latter treatment arm had a higher 1-year survival. No difference was observed between the use of the antireflux stents and conventional stents in relieving reflux. Previous chemoradiotherapy had no impact on complications, procedural deaths, and overall patient survival. Differences in outcomes among stents were minimal. CONCLUSIONS: Conventional self-expanding stents and anti-reflux stents are equally effective. Although the risk difference for 1-year survival favoured locoregional palliative treatment modalities, the latter were associated with a higher number of patients requiring reintervention.

INTRODUCTION: We describe a case of extragastrointestinal stromal tumor (EGIST) of the omentum harboring a novel KIT mutation and review the literature on omental EGISTs, emphasizing on molecular genetic data. CASE PRESENTATION: A large EGIST arising from the lesser omentum was incidentally diagnosed in a 68-year-old man during emergency laparotomy for intra-abdominal hemorrhage following a car accident. The tumor was composed of CD117+/CD34+ spindle-shaped cells with low mitotic activity. Analysis of tumor DNA revealed a heterozygous duplication of 30 bp in exon 11 of KIT. Nine months after R0 resection, positron emission tomography showed abnormal uptake in the upper abdomen. The patient was treated with imatinib mesylate and is alive and well 2 years after the operation. DISCUSSION: Omental EGISTs remain silent despite a large tumor size. They are diagnosed at a median age of 65 years and show low proliferative activity in the majority (about 80%) of cases. Although the median follow-up period of published cases is only 20 months, mortality appears to be low after R0 resection and is expected to decrease further following the recent introduction of imatinib therapy for high-risk tumors. Accumulating molecular genetic data may lead to improved prognostic classification and patient management.

This prospective randomized study aimed to evaluate the impact of hernia sac laparoscopy on the morbidity and mortality in cases with a spontaneous reduction of the strangulated hernia content before the assessment of its viability. Ninety-five patients underwent operation owing to incarcerated hernia. Forty-one patients, whose strangulated indirect inguinal hernia spontaneously reduced before the viability of the content was assessed, were included in this study. They were randomly assigned to 2 groups: group A (21 patients managed using hernia sac laparoscopy) and group B (20 patients managed without laparoscopy). The median hospital stay was 28 hours for group A and 34 hours for group B. Four patients of group B had major complications whereas there was none observed in the group A. Two unnecessary laparotomies and 2 deaths occurred in group B. Hernia sac laparoscopy seems to be an accurate and safe method allowing to prevent unnecessary laparotomy and especially in high-risk patients it contributes to decrease major morbidity.

AIMS: The objective of this study was to compare the perioperative, short-term, and long-term outcomes of stapled hemorrhoidectomy with Ferguson hemorrhoidectomy. MATERIALS AND METHODS: The present meta-analysis pooled the effects of outcomes of a total 926 patients treated with stapled or Ferguson hemorrhoidectomy in five out of 122 screened for retrieval randomized controlled trials using the fixed-effects or a random-effects model. RESULTS: Stapled hemorroidectomy was equivalent to the Ferguson procedure in comparisons pertaining to the following outcomes: hospital stay, postoperative hemorrhage requiring intervention, early postoperative bleeding <4 weeks, late postoperative bleeding <8 weeks, and the presence of anal pathology at 1 year follow-up. Stapled hemorrhoidectomy was superior with impact to operative time, pain visual analogue scale score at 24 h, urinary retention, and wound healing. CONCLUSIONS: There is convincingly apparent evidence about the safety and efficacy of stapled hemorrhoidectomy in the comparison with the well-established Ferguson procedure.

BACKGROUND: Experimental studies investigating transgastric endoscopic surgery report closure of the gastric wall incision with clips. The author of this report describes endoloop placement as an alternative, equally efficient, faster method for gastrotomy closure. METHODS: Eight female pigs with a mean weight of 30 kg were used. Abdominal endoscopic exploration and transgastric operations including hepatic biopsies, bilateral tubal ligation, cholecystectomy, and closure of the gastrotomy were performed. The experiment was divided into two parts. The first part included five animals, which were killed immediately after the procedure. The second part included five animals, which were kept alive and killed 15 to 20 days later. RESULTS: The first part of the experiment, performed for technical skills acquisition, involved transgastric abdominal exploration, liver biopsies, and bilateral tubal ligation, which were successful for all five animals. The gastric wall incision was closed by applying clips in four animals and endoloops in one animal. During the autopsy at the end of the experiment, the sites of intervention were examined macroscopically. In the second part of the experiment, gastrotomy closure with endoloop application was performed in two animals and with clip application in one animal. All three animals survived, gained weight, and demonstrated no signs of infection. They were killed 15 to 20 days after the procedure, and no signs of intraabdominal infection were found. Cultures from the peritoneal cavity were negative. At necropsy, macroscopic and microscopic examination confirmed complete healing of the gastrotomy. CONCLUSIONS: Transgastric endoscopic surgery is technically feasible and effective. The application of endoloops for closure of the gastric opening is a fast, easy, and equally safe alternative to clip placement.
