RESUMEN

INTRODUCTION: This case report describes a 14-year-old, male castrated York Shire Terrier, which was presented due to stranguria and tenesmus. An abdominal computed tomography (CT) scan raised a high suspicion of a persistent mullerian duct. During laparotomy structures were found that were suspected to be a persistent ovary and uterus. The abnormal uterus was filled with fluid and had a blind end on both sides. The abnormal structures were surgically removed and pathologically examined. Pathology confirmed a persistent mullerian duct. The patient recovered well from the surgery and was able to urinate spontaneously the same day and was discharged the next day.

INTRODUCTION: Ce rapport de cas décrit un York Shire Terrier mâle castré de 14 ans, qui a été présenté en raison d'une strangurie et d'un ténesme. Une tomodensitométrie (TDM) abdominale a soulevé une forte suspicion d'un canal de Müller persistant. Une laparotomie a été pratiquée, au cours de laquelle on a découvert des structures suspectées d'être un ovaire et un utérus persistants. L'utérus anormal était rempli de liquide et avait une extrémité aveugle des deux côtés. Les structures anormales ont été retirées chirurgicalement et ont fait l'objet d'un examen pathologique. La pathologie a confirmé la présence d'un canal de Müller persistant. Le patient s'est bien remis de l'opération et a pu uriner spontanément le jour même. Il a été autorisée à sortir le lendemain.

RESUMEN

Rectal tenesmus is a very uncomfortable symptom. Though antiarrhythmic drugs and nerve blocks have been proposed as a treatment for rectal tenesmus, none is well-established. We report a 68-year-old female who undertook surgery for uterine cervical cancer and underwent chemotherapy. She got a bilateral nephrostomy and bowel obstruction during the chemotherapy because of recurrence. She decided to stop chemotherapy and to receive palliative care. She had a symptom of rectal tenesmus, which was refractory to medications. The clinical sign was severe and uncomfortable, making her very nervous. We planned to treat the rectal tenesmus with a nerve block. A ganglion impar block was insufficient to remove the symptom, and the saddle block failed due to epidural lipomatosis. We finally succeeded in alleviating the sign with a neurolytic caudal epidural block. Relief of tenesmus made her hope to spend her final period at home. She could stay at home with her family for seven days before death without recurrence of the symptom. Though there is no report about the effectiveness of neurolytic caudal epidural block for rectal tenesmus, we consider the block appropriate for the symptom.

RESUMEN

Trichuris vulpis is a relatively common cause of canine large bowel disease leading to chronic diarrhea. Faecal analysis is negative most of the times due to long prepatent period and eggs may be shed intermittently. This case study done at Madras Veterinary College, Chennai, Tamil Nadu, India from 2014 to 2018 describes the usefulness of endoscopy in diagnosing the colitis due to presence of T. vulpis worms. Three dogs presented with haematochezia and tenesmus were subjected to detailed clinical examination. As the faecal examination was negative and there was no improvement on initial therapy endoscopy was performed. Numerous T. vulpis whip-worms were found attached to the colon mucosa on endoscopic examination. Multiple bleeding ulcerated sites were observed throughout the colon. The dog was treated with oral febental, praziquantal and pyrantal combination tablets (Drontal Plus). Clinical improvement was observed within a week.

RESUMEN

Introduction Long-term use of laxatives may have side effects such as bloating, allergic reaction, abdominal pain, metabolic disturbances, and hepatotoxicity. In this study, we have compared the efficacy of herbal medicine Nucarb, a combination of activated charcoal, calcium sennosides, peppermint oil, fennel oil, rhubarb extract, and purified sulfur, in relieving constipation. Methods This longitudinal study was conducted in multiple cities of Pakistan from April 2021 to June 2021. A total of 1000 patients, of either gender between age group 18 and 75 years, with complete spontaneous bowel movement of less than or equal to two times per week, were enrolled in the study. Participants were prescribed two tablets of Nucarb once daily (OD) at bedtime for the first seven days, followed by one tablet of Nucarb OD at bedtime for the following seven days. They were asked to return for follow-up after 14 days. Results There was a statistically significant improvement in all six components of constipation. After 14 days, the severity of constipation reduced by 80.70%, the sensation of straining was reduced by 72.69%, and the feeling of incomplete evacuation was reduced by 71.87%. There was no adverse event reported. Conclusion Nucarb is efficacious in reducing the severity of constipation, sensation of straining, bloating and abdominal pain, feeling of incomplete evacuation, and difficulty in passing gas. Since it is a herbal product, it can be safely used in all populations.

RESUMEN

RESUMEN Los lipomas suponen el 50% de los tumores de partes blandas. Podrían comprimir estructuras adyacen tes. Presentamos el caso de una mujer de 49 años con dolor anal intenso asociado a urgencia defecatoria, tenesmo, incontinencia y dispareunia. Presentaba tumoración blanda a nivel del glúteo derecho compa tible con lipoma. La resonancia magnética identificó una masa de 15,7 × 9 × 6 cm, de apariencia encap sulada, que se extendía por la fosa isquioanal e isquiorrectal con impronta sobre el músculo elevador del ano, desplazando el recto. Se efectuó exéresis en bloque, con alta en 48 horas sin complicaciones. El informe de Anatomía Patológica definitivo fue lipoma. Valoramos la asociación de lipoma e incontinencia fecal con una búsqueda en PubMed. Se obtuvieron 87 artículos de los cuales ninguno respondía al objeto del estudio. Esta sintomatología es un fenómeno excepcional en la literatura, que se diagnostica funda mentalmente mediante RM y ecoendoscopia. Gran resultado funcional tras la exéresis.

ABSTRACT Lipomas account for 50% of soft-tissue tumors and may compress adjacent structures. We report the case of a 49-year-old female patient with intense anal pain associated with defecation urgency, tenesmus, incontinence and dyspareunia. A soft tumor was present in the right buttock suggestive of lipoma. On magnetic resonance imaging an apparently encapsulated mass with a size of 15.7 × 9 × 6 cm was identified extending through the ischioanal fossa and ischiorectal fossa, displacing the levator ani muscle and rectum. The lesion was excised en bloc and the patient was discharged 48 hours later without complications. The pathology report concluded that the lesion corresponded to a lipoma. We performed a bibliographic search in PubMed to assess the association between lipoma and fecal incontinence; Of the 87 articles retrieved, none of them responded to the subject of the study. These symptoms are exceptional in the literature. The diagnosis is made mainly with magnetic resonance imaging and endoscopic ultrasound. An excellent functional outcome was achieved with surgical excision.

RESUMEN

We describe a case of prostate cancer recurrence 25 years after radical prostatectomy. Our patient is a 77-year-old male with past medical history pertinent for obesity and coronary artery disease. The patient's initial presentation in 1994 was for persistent lower urinary tract symptoms. He was subsequently diagnosed with high-grade prostate adenocarcinoma and underwent radical prostatectomy. The patient was followed up postoperatively for 16 years and deemed to be in clinical and biochemical remission with undetectable prostate-specific antigen (PSA). Twenty-five years post-operatively, the patient was evaluated with an investigatory colonoscopy for tenesmus, constipation, and change in stool caliber. Colonoscopy revealed significant anal canal stenosis. Biopsy of the lesion showed prostate adenocarcinoma recurrence. Prostate cancer recurrence presenting with only gastrointestinal symptoms is highly unusual, especially in a patient who never received radiotherapy and had been in remission for 25 years.

RESUMEN

Dogs with benign intra-pelvic rectal or vaginal masses show symptoms indicating compression on the adjacent organs. Clinical signs usually develop late when the lesion is large enough to interfere functionally. The dogs were referred for severe fecal and/or urinary tenesmus. The data collected included signalment, clinical signs, results of physical examination, pre-surgical diagnostic tests, surgical technique used, surgical complications and histological findings. Digital rectal and vaginal examination allowed the detection of a mass occupying space in the pelvic cavity in all patients. Abdominal ultrasonography and/or total body computed tomography (CT) were used to better characterize the lesion and to exclude a metastatic spread of the tumor in case of malignancy. A dorsal approach to the rectum, a dorsal episiotomy, a midline celiotomy, and a combined perineal and abdominal approach were performed to remove the mass. No postoperative complications were observed. Benign and well-differentiated malignant mesenchymal neoplasms were histologically diagnosed. As a consequence of the chronic urethral compression caused by the mass, urinary incontinence and/or urinary retention were observed for a few postoperative days. Fecal tenesmus resolved in all cases in the immediate postoperative period. The dogs' quality of life quickly improved after surgery, especially considering the serious and life-threatening pre-surgical clinical conditions. Both the recovery time after surgery and overall survival were also evaluated.

RESUMEN

Gastrointestinal arteriovenous malformation (AVM) is reported as one of the possible causes of intestinal bleeding, and its occurrence in the rectum is rare. We report the case of a rectal AVM patient who experienced uncommon symptoms of anal pain and tenesmus and was treated successfully with percutaneous transarterial ethanol sclerotherapy. The patient underwent routine colonoscopy with biopsy at the time of visit; however, an accurate diagnosis was difficult. Subsequent contrast-enhanced computed tomography (CT) and angiography revealed a rectal AVM emerging from the distal inferior mesenteric artery with engorged superior rectal veins. The feeding artery was catheterized, and concurrent transarterial sclerotherapy with 80% ethanol was performed. There was no major complication related to the procedure. Disappearance of AVM nidus and improvement of associated venous congestion were shown by follow-up CT. There was no recurrence of symptoms after 10 months of clinical observation. Transarterial ethanol sclerotherapy is safe and effective in treating rectal AVM and can be considered as one of the nonsurgical treatment options.

RESUMEN

PURPOSE: The aims of this study were to examine the prevalence of myoclonus, sweating, pruritus, hiccup, and vesical and rectal tenesmus, and to explore associated factors in patients with advanced cancer. METHODS: This multicenter prospective cohort study was conducted in 23 inpatient hospices/palliative care units in Japan from January to December 2017. The prevalence and characteristics of each symptom were assessed on admission and in the 3 days before death. We selected factors that might influence the occurrence of each symptom and investigated the association. RESULTS: A total of 1896 patients were enrolled. The prevalence of orphan symptoms rose from admission to the 3 days before death: myoclonus 1.3 to 5.3% (95% CI 0.9-1.9%/4.3-6.5%), sweating 1.8 to 4.1% (95% CI 1.3-2.6%/3.1-5.1%), hiccup 1.1 to 1.8% (95% CI 0.7-1.7%/1.2-2.6%), and tenesmus 0.7 to 0.9% (0.4-1.2%/0.5-1.5%). Prevalence of pruritus fell from 3.5 to 2.5% (95% CI 2.7-4.4%/1.8-3.4%). Sweating, pruritus, and hiccups persisted throughout the day in nearly half of the patients. Myoclonus was significantly associated with brain tumors, sweating with opioids and antipsychotics, pruritus with liver and biliary tract cancer, cholestasis and severe diabetes, hiccup with male gender, digestive tract obstruction, severe diabetes, and renal failure. Vesical tenesmus was associated with urinary cancer, antipsychotics, and anticholinergics and rectal tenesmus with pelvic cavity cancer. CONCLUSION: We found that orphan symptoms occurred in 0.5-5.0% of patients, increased over time except for pruritus, and persisted in half of the patients.

RESUMEN

Gabapentinoids could be assumed to relieve cancer-related rectal/vesical tenesmus based on their pharmacological mechanism. Four patients were refractory for cancer-related rectal/vesical tenesmus although their opioid doses were titrated up. Symptom intensity difference (SID) between initiation and follow-up after 24, 48, and 72 h and daily changes in the frequency of urination, defecation, opioid rescue doses, presence of sleep disruption, and dose of regular opioid medication were evaluated. The median reductions in daily discomfort measured as SID between baseline and follow-up after 24, 48, and 72 h were 87.5%, 70.0%, and 80.0%, respectively, while those in daily pain intensity were 75%, 66.7%, and 66.7%, respectively. The initiation dose of gabapentin was 200 or 400 mg/day and that of pregabalin was 75 mg/day in one patient. Gabapentinoids were effective at low doses administered over a short duration to patients with refractory cancer-related rectal/vesical tenesmus.

RESUMEN

BACKGROUND AND PURPOSE: This study aimed to identify anatomically-localised regions where planned radiotherapy dose is associated with gastrointestinal toxicities in healthy tissues throughout the pelvic anatomy. MATERIALS AND METHODS: Planned dose distributions for up to 657 patients of the Trans Tasman Radiation Oncology Group 03.04 RADAR trial were deformably registered onto a single exemplar computed tomography dataset. Voxel-based multiple comparison permutation dose difference testing, Cox regression modelling and LASSO feature selection were used to identify regions where dose-increase was associated with grade ≥2 rectal bleeding (RB) or tenesmus, according to the LENT/SOMA scale. This was externally validated by registering dose distributions from the RT01 (n = 388) and CHHiP (n = 241) trials onto the same exemplar and repeating the tests on each of these data sets, and on all three datasets combined. RESULTS: Voxel-based Cox regression and permutation dose difference testing revealed regions where increased dose was correlated with gastrointestinal toxicity. Grade ≥2 RB was associated with posteriorly extended lateral beams that manifested high doses (>55 Gy) in a small rectal volume adjacent to the clinical target volume. A correlation was found between grade ≥2 tenesmus and increased low-intermediate dose (∼25 Gy) at the posterior beam region, including the posterior rectum and perirectal fat space (PRFS). CONCLUSIONS: The serial response of the rectum with respect to RB has been demonstrated in patients with posteriorly extended lateral beams. Similarly, the parallel response of the PRFS with respect to tenesmus has been demonstrated in patients treated with the posterior beam.

RESUMEN

Background: Malignant rectal pain (MRP) and tenesmus cause significant morbidity for cancer patients at all stages of disease. There is little evidence to guide management of these symptoms. Objective: The objective of this review was to summarize the existing evidence base for palliative management of MRP and tenesmus outside of standard oncologic or surgical management. Design: A systematic review of PubMed and Embase was conducted according to PRISMA guidelines using preselected search terms for publications between 1980 and January 2017. Setting/Subjects: Studies that described management for patients with tenesmoid pain from malignant tumors of the rectum, anus, or perineum were identified. Measurements: The primary outcome was response of pain to treatment. Results: The search produced 1412 titles. Twenty articles met criteria for inclusion in the review, including 11 case series and 9 case reports. A variety of treatments were found with most patients receiving interventional procedures, but overall evidence to support any particular intervention is limited and of poor quality. Conclusions: This review highlights the limited current evidence base for medical and interventional treatments for MRP and tenesmus. Further study is needed to clarify the best approach to managing these challenging symptoms.

RESUMEN

Introduction: Rectal tenesmus pain in cancer patients most frequently appears in patients with colon cancer, and as a consequence of radiotherapy of the hypogastrium region. Treatment with opioids and adjuvant analgesics is often ineffective. Patients and methods: Here, we report on two female patients diagnosed with colon and ovary cancer, respectively, who had very severe tenesmus pain (numerical rating scale 8-10) despite using high doses of opioids, including methadone with corticosteroids, anticonvulsants, antidepressants and ketamine. Results: In both patients, bupivacaine was administered via a rectal enema. In the first patient, bupivacaine was administered at a dose of 100 mg 0.1% (100 mL), and subsequently 100 mg 0.2% (50 mL), leading to effective analgesia for 8 and 12 hrs, respectively. In the second patient, 100 mg 0.1% (100 mL) was initially administered, followed by 100 mg 0.2% (50 mL), leading to effective analgesia for 12 and 17 hrs, respectively, with only dull abdominal pain reported that was relieved by 100 mg IV ketoprofen and complete disappearance of tenesmus pain. Rectal bupivacaine administration did not cause neurologic adverse effects, heart function disturbances or decreased blood pressure. A volume of 50 mL was enough to cover a painful area in the colon. Initial bupivacaine concentrations in the blood serum did not exceed 50 ng/mL and eventually dropped to 20 ng/mL and below. Conclusions: Administration of 100 mg bupivacaine as a rectal enema is safe and provides effective analgesia, and this procedure may be conducted in hospital departments and out-patient clinics. Furthermore, this procedure in the case of pain recurrence, can be repeated, and by providing effective pain relief often allows time for the patient to be transferred to a specialized pain center.

RESUMEN

Rectal irritative symptoms in cancer patients are often refractory to treat and exacerbate their quality of life. We experienced a peadiatric case of rectal irritative symptoms treated by Yokukansan. A 9 year-old boy developed rectal irritative symptoms as itching sensation in rectum caused by relapsed rhabdomyosarcoma in pelvis. Oral Yokukansan, which is common Japanese Kampo medicine for temper tantrum of children, was administered and relieved his symptoms. Yokukansan is known as adjuvant drug for neuropathic pain. It could be one of the adjuvant drugs for refractory symptoms in palliative care setting.

RESUMEN

BACKGROUND: Solitary rectal ulcer syndrome (SRUS) is a benign and chronic disorder well known in young adults and less common in children. The objective of this study was to determine the frequency and clinical spectrum of solitary rectal ulcer in children with bleeding per rectum. METHODS: This study was conducted in the Department of Paediatric Gastroenterology Hepatology& Nutrition; The Children's Hospital & The Institute of Child Health, Lahore, from January-December 2015. Total 187 children presenting with per-rectal bleeding who underwent colonoscopy were entered in the study. Demographic and presenting clinical features; colonoscopy and histopathology findings were recorded. Data was analysed using SPSS-20. RESULTS: Out of a total of 187 children with bleeding per rectum, 21 (11.23%) were diagnosed with solitary rectal ulcer. Males were 15 (71.43%) and females were 6 (28.57%) with age range 8-12 years. Mucus in stool 14 (66.7%), constipation 12 (57.1%) and tenesmus 10 (47.6%) were the most common clinical presentations. Colonoscopic finding are solitary erythmatous ulcerative lesion was seen in 8 (38.09%) children, multiple ulcerative lesions in colon 6 (28.57%), multiple ulcerative lesions in rectum 5 (23.81%), polypoidal growth in colon and hyperaemic rectal mucosa in 1 (4.76%) each. Histopathological findings were consistent with SRUS in all the cases. CONCLUSIONS: The frequency of SRUS was high (19.6%) in patients with per-rectal bleed. Mucus in stool, constipation and tenesmus were the most common clinical presentations. Colonoscopic and histopathological findings were helpful in the confirmation of the underlying aetiology.

RESUMEN

AIM: Tenesmus in rectal prolapse leads to a vicious circle of straining with deterioration of prolapse. The primary phenomenon triggering this may be rectal hypersensitivity. We aimed to assess whether treatment with tricyclic antidepressants (TCAs) may break the vicious circle and improve tenesmus. METHOD: A retrospective review was carried out of patients with rectal prolapse and severe tenesmus who were poor surgical candidates or had refused surgery. They were treated at our tertiary centre with low dose tricyclic antidepressants. RESULTS: Twenty-three (18 female) patients were included, with mean age 75.3 (±SD 14.6) years. The mean duration of symptoms was 10.8 (± 8.6) months. Full-thickness rectal prolapse was diagnosed in 16 (70%) patients while seven (30%) had mucosal or incomplete prolapse. Ten (43%), eight (35%) and five (22%) patients were treated with nortriptyline (25 mg daily), amitriptyline (10 mg daily) and desipramine (25 mg daily). After a mean follow-up of 9.05 (± 8.2) months, 14 (61%) patients reported significant improvement in symptoms, five (22%) had a partial response, three (13%) were lost to follow-up and one (4%) failed to respond. The response rates for nortriptyline, desipramine and amitriptyline were 90%, 100% and 62.5%. CONCLUSION: To the best of our knowledge this is the first report to address the symptomatic, conservative treatment of tenesmus in patients with rectal prolapse. TCAs may be an acceptable option for poor surgical candidates or patients refusing surgery.

RESUMEN

BACKGROUND: The medical management of hemorrhoids should include an integrated approach. This integrated approach can be achieved by polyherbal formulations containing anti-inflammatory, styptics, analgesics, and laxative effect which reduce inflammation, pain, and bleeding, and increase gastro-intestinal motility and soften stools. One such polyherbal kit is "Arshkeyt™, a 7 day kit," which consists of oral tablets and powder along with topical cream. OBJECTIVE: Efficacy and safety of Arshkeyt™, a 7 day kit, a marketed polyherbal formulation was evaluated in comparison with conventional therapy practiced in surgery outpatient departments. MATERIALS AND METHODS: Patients (n = 90) with hemorrhoids were randomly allocated to receive either Arshkeyt™ or standard therapy (combination of oral Isabgul powder and 2% lidocaine gel) for 14 days. Assessment on the basis of rectal symptoms and proctoscopic examination was done on day 0, 7, and 14 to derive a "composite score" which ranged from 0 to 25 by a blinded evaluator. The primary endpoint was number of patients achieving composite score 0 at the end of therapy (day 14). Inter-group analysis was done using Chi-square test. RESULTS: On day 14, the composite score of 0 was achieved in 15 patients of Arshkeyt™ group versus 6 patients receiving standard therapy. The symptoms and signs which showed significant improvement in Arshkeyt™ group compared to standard treatment group were the tenesmus (visual analog score) score (P = 0.047), anal sphincter spasm (P = 0.0495) and a decrease in the grade of hemorrhoids (P = 0.0205) on day 14. Arshkeyt™ was also more beneficial in case of bleeding hemorrhoids as compared to nonbleeding hemorrhoids (P < 0.05). The incidence of adverse drug reactions in both groups was comparable and no patient required any treatment for the same. CONCLUSION: "Arshkeyt™, a 7 day kit," was effective in the treatment of hemorrhoids and had a good safety profile.
