We report the value and usefulness of the proctoscope in one of the modern orthopaedic procedures. We have found the proctoscope more effective than the currently available instruments as tissue protector during intramedullary nailing. We briefly describe our technique of using the proctoscope and discuss its advantages.

BACKGROUND: Elastic band ligation by means of a rigid proctoscope is the treatment of choice for patients with symptoms caused by internal hemorrhoids of grade 2 to 3. In contrast to the flexible videoendoscope, the rigid proctoscope has limited maneuverability, has a narrower field of view, and does not allow adequate documentation. Therefore, a randomized trial was conducted to compare the safety and the efficacy of conventional elastic band ligation with videoendoscopic elastic band ligation. METHODS: A total of 100 consecutive patients (mean age 47 [12] years) with chronically bleeding grade 2 or 3 internal hemorrhoids were randomized to elastic band ligation or videoendoscopic elastic band ligation. For videoendoscopic elastic band ligation, a reusable multiband ligator was attached to the end of a therapeutic upper videoendoscope. From one to 3 bands were placed per session in both groups. Re-treatment was performed every 2 to 3 weeks in both groups until cessation of bleeding and eradication of the hemorrhoids (at least grade 2) were achieved. Thereafter, the patients were followed to assess complications and efficacy. Recurrent bleeding was considered a treatment failure. RESULTS: To achieve the desired therapeutic aims, a significantly lower number of treatment sessions was required in the videoendoscopic elastic band ligation group (1.8 [0.8] vs. 2.4 [0.9]; p < 0.01) and the total number of bands applied was significantly less (2.8 [1.1] vs. 3.7 [1.4]; p < 0.01). Pain was noted after ligation by 25% of patients in the elastic band ligation group compared with 27% of those who had videoendoscopic elastic band ligation. However, analgesic medications were required in only 7% after elastic band ligation and 9% after videoendoscopic elastic band ligation (NS). Post-ligation bleeding that had to be treated endoscopically occurred in 3.5% of the patients of the elastic band ligation group and 3.2% of those in the videoendoscopic elastic band ligation group (NS). Blood transfusion was not required. At a median follow-up of 12 months, there was no recurrence of bleeding in 40 patients (80%) in the conventional elastic band ligation group vs. 43 (86%) in the videoendoscopic elastic band ligation (NS). CONCLUSIONS: The long-term efficacy and safety of conventional elastic band ligation and videoendoscopic elastic band ligation are highly comparable. However, when videoendoscopic elastic band ligation is performed, significantly fewer treatment sessions are required.
BACKGROUND: Per-anal excision can be an effective method for treating large rectal adenomas and selected rectal cancers. This procedure is suitable for adenomas that are too large for colonoscopic excision and for early rectal cancers in patients that are unfit for major resection. PATIENTS AND METHODS: We retrospectively reviewed 37 patients (16 male, 21 female) that had a local resection using a Salvati operating proctoscope. Fifteen had rectal cancer and 22 had rectal adenoma and all have been followed-up for a median of 14 months (range 2-65). Most cancers were staged pre-operatively with endorectal ultrasound and 6 cancer patients received adjuvant therapy. RESULTS: There were no intra-operative complications, 6 minor postoperative complications, none requiring re-intervention (1 peri-anal haematoma, 2 postoperative anaemia, 2 chest complications, 1 secondary haemorrhage) and no peri-operative deaths. Lesions were histologically completely excised in 33 (89%). Thirty-four (92%) did not have any recurrence, 2 (5%) adenomas recurred (both successfully treated with further local resection) and 1 (3%) failed to attend for follow-up. Six have since died, all from comorbid conditions. CONCLUSION: Local resection of rectal tumours using the operating proctoscope is a low cost technique with a low complication rate. Outcome of this treatment is good, and similar to other surgical modalities. Local tumour recurrences are uncommon and can be successfully treated with further local treatment.
The proctoscopic diagnosis of haemorrhoids may be influenced by the surgeon's knowledge of the presence or absence of associated symptoms. In this study, an observer with no knowledge of the history, was used to check the surgeon's proctoscopic findings in 12 asymptomatic controls, and 24 symptomatic patients on 2 occasions, the latter group undergoing McGivney rubber band ligation. There was very good correlation between the findings of the surgeon and the observer, indicating a lack of 'historical bias'. The documentation method designed to allow this comparison proved sufficiently accurate and reproducible to enable a correlation between haemorrhoidal mass and symptoms. Relief of symptoms after treatment correlated well with an objective reduction in haemorrhoidal mass.
Eight hundred and twenty-three examinations were carried out on 662 homosexual patients. At each examination a blind anorectal swab and a rectal swab taken via a proctoscope were inoculated on to a culture plate. From a total of 100 gonococcal infections of the rectum 96 gave positive results from blind anorectal swabs and 99 from swabs taken via a proctoscope. Blind anorectal swabs proved to be a reliable method in the diagnosis of rectal gonorrhoea.
To determine whether laxatives alter the proctoscopic and morphological appearances of the human rectum, 10 normal subjects were studied prospectively, and the following manipulations were assessed in a randomized, blinded manner: no treatment; oral mannitol to induce diarrhea; isotonic saline enema; Fleet's Phospho-Soda enema; and bisacodyl (Dulcolax), 10 mg, by enema or suppository. The rectal mucosa after mannitol-induced diarrhea, or after saline enema could not be distinguished from untreated rectum by proctoscopy, light microscopy, or scanning electron microscopy. Fleet's enema, and bisacodyl invariably changed proctoscopic appearances, and frequently altered light and scanning microscopic aspects. Both Fleet's enema and bisacodyl caused sloughing of surface epithelium. In addition, bisacodyl decreased the uptake of hematoxylin and eosin by crypt epithelial cells so that the affected cells had a partially erased appearance (16 of 25 biopsies examined by light microscopy). The lamina propria of 3 of these 25 biopsies contained polymorphonuclear cells. Transmission electron microscopy revealed that the abnormal crypt epithelial cells contained fewer cytoplasmic organelles and less nuclear chromatin. All lesions resolved within 7 days. Fleet's enema and bisacodyl by rectum may mislead the proctologist and the pathologist by altering normal rectal mucosa.
New operating proctoscopes have been designed that facilitate the passage of a stapling head without its anvil in rectal procedures which call for this technique to be used.
An improvised method of using a proctoscope as a protector during the reaming procedure for closed retrograde femoral nailing is described. This protector is easy to handle and can be effectively used to protect the intra-articular structures, patellar cartilage and patellar tendon during the reaming process. The protector can also help minimise the reaming bone dust spilling out into the joint cavity.
It has been suggested that a barium enema may safely follow a colorectal biopsy superficial to the muscularis propria within 24 hours, but that the colon radiograph should be postponed 3 to 7 days following a biopsy including this layer. The authors prospectively studied 67 colorectal biopsies obtained with the Wolf 3-mm (grasping) and 5-mm (cutting) proctoscopic forceps from 49 patients to determine the depth of the biopsies. The 5-mm biopsies were not significantly deeper than the 3-mm biopsies (p greater than 0.5). In 18 patients biopsied with each instrument, the 3-mm biopsy was deeper in two cases (11%), the 5-mm biopsy was deeper in three cases (17%), and the biopsies were of equal depth in 13 cases (72%). None of the biopsies with either forceps reached the muscularis propria. The authors concluded that it may be unnecessary to wait longer than 24 hours before performing a barium enema after colorectal biopsy with these forceps.
Painless bright red peranal bleeding is a leading symptom of first and second degree hemorrhoid. After having excluded the possibility of bleeding in an upper region diagnosis is made proctoscopically, which is generally followed by injection therapy. Arterial blood supply can be reliably imaged with the aid of 20 MHz microvascular Doppler sonography and the success of therapy can be verified as well as documented after injecting a sclerosing substance.
PURPOSE: Endoscopic Doppler sonography is a relatively new technique in the diagnostics of intestinal hemorrhage. It has been used mainly for bleeding gastroduodenal ulcers, but can also be utilized in the lower digestive tract. METHODS: In the study presented 80 patients with symptomatic hemorrhoids of first degree and previous hemorrhage were randomized in two groups. The 40 patients in Group A were examined by transproctoscopic Doppler ultrasound. After measuring the vessels depth, local injection treatment with 5 percent phenol almond oil followed. The patients in Group B had been given conventional sclerotherapy without the aid of Doppler investigation. The success of treatment was checked using Doppler sonographics six weeks later and the results were statistically compared. RESULTS: In the patients in Group A, the hemorrhoids proved to be totally eliminated in 93 percent vs. 38 percent of the patients in Group B (P, 0.1 percent). CONCLUSIONS: Proctoscopic Doppler ultrasound is useful in the evaluation and sclerotherapy of symptomatic first-degree hemorrhoids.
On the basis of the endoscopic appearance, 71 rectal polyps were assessed as adenomata or non-neoplastic polyps, after which the endoscopic diagnosis was compared with the results of histological examination. The diagnosis based on macroscopic examination of the polyps proved correct in only 62% of the cases. It is concluded that the diagnosis of adenoma cannot be established solely on the proctoscopic appearance of a polyp and, as adenomata are premalignant, removal of all polyps found at proctoscopy is recommended.
