Hemorrhoidal disease is considered to be one of the most common anorectal pathological conditions worldwide. Though symptomatic hemorrhoidal disease significantly hampers the quality of life, in most cases, patients are disinclined to seek medical attention. This makes it difficult to determine the exact incidence of the condition. Hemorrhoid disease is said to be the fourth leading outpatient gastrointestinal diagnosis, accounting for 3.3 million ambulatory care visits in the United States [1]. Although so common, only around 4% seek medical help [2]. Levels of spontaneous consultation for hemorrhoidal symptoms worldwide are only around 2%, increasing to around 14% when patients presenting for an unrelated condition are subject to targeted questioning [3] [4]. The most common complaints related to hemorrhoids are bleeding, pain during defecation, swelling, prolapse, itching and fecal incontinence.

The exact pathophysiology of hemorrhoidal disease is still not completely understood. Several mechanisms may be involved including sliding anal cushion, hyperperfusion of hemorrhoidal plexus, vascular abnormality, tissue inflammation, and internal rectal prolapse. Factors like constipation, straining during defecation, pregnancy, obesity aggravate the above-mentioned pathologic changes. These factors are also involved in chronic venous disease development. The co-morbidity of these two disease conditions is yet to be properly evaluated.

The different philosophies of hemorrhoidal disease development may lead to different approaches to the treatment of hemorrhoids [5]. Dietary and lifestyle modifications remain the primary choice of physicians for hemorrhoidal disease management. Other treatments include pharmacological approach, hemorrhoidectomy, and other non-excisional surgeries.

In light of these data, this study aimed to determine the frequency of complaints such as pain, bleeding, rectal swelling, itching, soiling, as well as constipation in subjects consulting for hemorrhoids and to assess the possible concomitance between hemorrhoids and chronic venous disorders.

This was a multi-center, cross-sectional, observational study. The study was conducted by 20 Physicians involved in hemorrhoidal disease management from 17 hospitals located in different regions of Bangladesh. The study period lasted for 2 months, from 1^st June 2018 to 31^st July 2018. Convenient sampling technique was used for selection of the study sample. After obtaining informed consent, 499 Patients aged over 18 years and consulting spontaneously for hemorrhoidal complaints or referred by another physician for hemorrhoids were enrolled. Patients who were consulting for other emergencies except hemorrhoids were excluded from the program. Informed written consent was taken from all the participants. Ethical approval was taken from the Department of Surgery, US Bangla Medical College, Narayanganj, Bangladesh.

Demographic data and lifestyle characteristics of the subjects were collected including age, sex, body mass index, occupationally activeness, duration of standing position in a day, smoking habits, and obstetrical history. Subjects were asked to describe their anal complaints including symptoms, presence or duration of constipation, duration of evacuation, use of laxatives, consistency of stools in the last 15 days using the Bristol stool scale, [6] history of hemorrhoids. Patient examination, if performed, was described (digital and/or anoscopy) and the type (internal, external or mixed) and grade of hemorrhoids were noted. Internal hemorrhoids were graded from I to IV according to the classification of Goligher et al. [7] Patients were also questioned about the chronic venous disease of the lower extremities and chronic venous disease was graded according to the revised CEAP (Clinical manifestations, Etiologic factors, Anatomic distribution of disease, and underlying Pathophysiology) classification [8]. Details of any hemorrhoidal treatment prescribed including dietary fiber, topical treatment, veno-active drugs, pain killers, and surgery (including minimally-invasive procedures) were recorded. All necessary information was collected through a detailed questionnaire and test results of participants, and the collected data was compiled and analyzed using SPSS software.

The study included 499 patients with hemorrhoids who met the selection criteria. The mean age was 38.6 ± 11.4 years (range 15 - 83 years) and the male:female ratio was 1.6:1 [Table 1]. BMI was normal for most of the participants [Table 2]. 71.5% of the participants were occupationally active [Table 3]. Duration of standing position during the day was less than 2 hours for 46.7% of the participants [Table 4]. Most of the participants (60.5%) were nonsmokers [Table 5]. Most of the participants (87.4%) had given birth before [Table 6]. Less than 18 months of constipation was recorded for most of the participants [Table 7]. 32.1% were laxative medication users [Table 8]. 67.1% of participants had evacuation lengths of 6 to 30 minutes [Table 9]. Consistency of stools in the last 15 days (without laxatives) were type 3 in 23.8% of participants [Table 10]. History of hemorrhoids was present in 68.1% and among them, history of hemorrhoids once was present in 43.8% [Table 11]. 92.4% were examined. Among them, 38.9% were digitally examined [Table 12]. Grade 2 hemorrhoids were present in the maximum (37%) number of the participants after examination [Table 13]. The most frequently encountered complaints were bleeding (80.8%), pain (66.3%), swelling (51.7%), prolapse (28.9%), itching (37.7%), soiling (12%) and fecal incontinence (13.4%) [Figure 1]. Among the hemorrhoidal patients, 13.8% presented concomitant chronic venous disease. CEAP classification was used to classify the clinical signs and symptoms of the patients as C0 (6.2%), C1 (4.4%), C2 (1.4%), C3 (2.6%), C4a (2%), C4b (0.2%) and C5 - C6 (0.6%) [Figure 2]. Maximum patients (89.8%) were prescribed Dietary fiber. Topical treatment,

veno-active drugs, analgesics were prescribed as conventional treatments in respectively 63.7%, 74.7%, and 11.2% of the patients. 30.3% of the patients underwent surgical procedures [Figure 3]. MPFF was the most prescribed veno-active drug (87.1%). 12.3% and 0.7% of the patients were prescribed Diosmin and Calcium Dobesilate respectively [Figure 4]. 73.4% of patients continued veno-active drugs for more than 4 weeks. 17.4% and 9.2% continued for 2 - 3 weeks and less than 1 week, respectively [Figure 5].

Almost all the participants (94.2%) underwent a clinical examination, either digital and/or anoscopic. Although a digital examination cannot always confirm a diagnosis of lower grade HD, it is important to eliminate any local malignancies. Anoscopy is necessary for the diagnosis of Grade I hemorrhoids and was performed in most patients with low-grade hemorrhoids, thus confirming the high level of diagnostic evidence in this study.

Patients from the age group of 31 - 40 years were most in numbers to consult for hemorrhoidal problems. Male predominance was found among the patients (61.7% vs. 38.3%). This may reflect the cultural habits of people living in Bangladesh making women with HD reluctant to come forward.

87.4% of the female patients had had at least one full-term pregnancy, and pregnancy is recognized as a risk factor for all grades of hemorrhoids. Hemorrhoids are common during pregnancy, particularly the last trimester, [9] [10] and although they generally resolve after delivery these women are at greater risk of hemorrhoids later in life. 29.5% of the patients were in the overweight category. and 13.8% were in the obese category. Some previous studies have hypothesized that obesity may be a risk factor for HD because of increased intraabdominal pressure and increased stress on rectal muscles [11].

Several studies in the past, including those that have used colonoscopy to confirm hemorrhoids, have shown an increased risk in patients with chronic constipation [12] [13] [14]. Whether causal or a contributory factor in the presence of a primary cause, prolonged straining increases intra-abdominal pressure and raises venous pressure in the hemorrhoidal tissue. In this study, more than half of the subjects (59.9%) were suffering from constipation according to the Bristol stool scale and 67.1% reported a straining duration of 6 - 30 minutes.

Hemorrhoid recurrence rates have been reported to range from 4% - 30% after treatment [15]. In this study, 68.1% of patients had had hemorrhoidal attacks previously.

Grade II hemorrhoids were found to be the most common (37%) hemorrhoidal grade among the patients in this study followed by grade III (27.9) and grade I (26.6%) hemorrhoids. This may be because patients are often ignorant of painless bleeding or are reluctant to consult with physicians unless the symptoms are severely hampering their day-to-day lives. Bleeding (80.8%) followed by pain (66.3%) and swelling (51.7%) were the most common complaints presented.

Hemorrhoidal disease and chronic venous disease may have a common cause in the form of loss of vascular integrity, [16] though there are few published papers on the coexistence of these two disorders [17]. An early review of epidemiologic evidence for a link between HD and CVD hypothesized that chronic constipation associated with a low fiber diet was involved in both these diseases by increasing intra-abdominal pressure [17]. It was suggested that this pressure would easily be transmitted to the hemorrhoidal plexus, which has no valves. The valves of the lower limb veins would offer initial protection, but would eventually become incompetent and expose the veins to elevated pressure [17]. This hypothesis is supported by data from a Hungarian epidemiologic study of pregnant women, which found that around half with a diagnosis of HD also had constipation. Varicose veins were also more common in pregnant women with hemorrhoids compared with those without [18]. 13.8% of this study subjects also presented with signs and/or symptoms of CVD, the majority having a CEAP classification of C0s to C1. The finding should prompt physicians treating patients with a hemorrhoid diagnosis to also ask about CVD and vice versa.

Non-surgical approaches are preferred for lower-grade hemorrhoids because of the physiologic importance of the hemorrhoid cushions and the potential self-limiting nature of many hemorrhoidal symptoms [10] [15] [19] [20]. When conservative therapy fails, clinical practice guidelines recommend office-based procedures such as banding, sclerotherapy, and infrared coagulation for Grade I to III hemorrhoids [19] [21]. Surgical options such as hemorrhoidectomy, stapled hemorrhoidopexy, or hemorrhoidal artery ligation may be the initial step in patients with Grade III or IV hemorrhoids or in those who are refractory to or cannot tolerate office procedures [19] [21]. However, conservative therapy can still play a role, creating favorable conditions for a smooth post-operative recovery [22]. Adherence to these guideline recommendations is important to avoid repetitive and prolonged treatment and severe complications in Grade IV disease. The majority of the patients in this study received treatment with a veno-active drug, predominantly MPFF. MPFF is an effective treatment for acute hemorrhoidal attacks, and it has been shown to serve as an effective adjuvant to surgery or other procedures in the management of hemorrhoidal diseases [23]. MPFF is able to address the underlying causes of both symptomatic hemorrhoids and CVD via their beneficial effects on venous tone, inflammatory processes, and microcirculatory permeability [24]. Early use of such agents may play a role in preventing or slowing the development and recurrence of both hemorrhoidal and CVD signs and symptoms [25] [26].

This study was conducted in multiple centers, and under different physicians, but the communication between the physicians was not strong. The study sample was also small compared to original goal. The sensitivity of the study topic also posed a limitation on how much data was able to be collected.

This study provided small-scale data on the profiles of patients presenting with HD in clinical practice. Factors like older age, obesity, constipation, increased evacuation time, male gender, and pregnancy were identified as having a statistically significant association with hemorrhoidal disease. Further studies are needed to confirm the co-relation between HD and CVD. If confirmed, a common targeted therapy needs to be given for both diseases. Moreover, since patients are less likely to spontaneously come forward with hemorrhoidal symptoms, physicians should consider the above-mentioned risk factors and be proactive in diagnosing hemorrhoids if suspected. As hemorrhoidal symptoms affect patients in all grades, a conservative treatment therefore should be the cornerstone of care.
