Background: Recommended treatment for complicated peri-rectal abscess is incision and drainage (I&D) in conjunction with antibiotics. However, there is no standard antibiotic regimen for post-opera...

Objective: To observe and research the influence degree of hyperbaric oxygen therapy on wound healing and related serum indexes of rectal abscess patients after surgery. Methods: A total of 48 rectal abscess patients treated with operation in my hospital from April 2014 to August 2015 were taken as research objects, and the 48 patients were randomly divided into two groups: control group (postoperative routine treatments, 24 cases) and observation group (postoperative routine treatments and hyperbaric oxygen therapy, 24 cases), and then compared the time constitutes of wound healing, the edema degrees and the related serum indexes of patients in two test groups before the operation and at 1 d, 3 d and 10 d after operation. Results: The time constitute of wound healing of observation group is better than that of control group, and the edema degree and the related serum index of observation group are lower than those of control group, and the test result of two groups have significant differences. Conclusions: The hyperbaric oxygenation therapy can effectively promote the postoperative wound healing of patients with rectal abscess, and it also has active clinical significance for the control of edema and related serum indexes.

A 25-year-old homosexual man, not regular with treatment, presented with fever, rectal pain and intermittent haematochezia. He had been diagnosed with HIV/AIDS 1 year prior. Examination showed anal condylomas and non-tender inguinal lymphadenopathy. CD4 count was 74/µL. CT scan of abdomen and pelvis showed a small hypodense collection with peripheral enhancement in the left perirectal region, measuring 1.9×1.4×2.5 cm (figure 1A). A diagnosis of rectal abscess was made. Treatment was done with intravenous antibiotics. Patient’s symptoms improved after 7 days of treatment. Two months …

Three male patients without accompanying diseases, 27, 47, and 52 years of age, were admitted with fever of unknown origin. Focal liver disease was seen on ultrasound and the diagnosis of an abscess was confirmed by sonographically-guided fine-needle puncture. Microaerophilic streptococci were found in two cases, streptococcus viridans once. Two patients had cryptogenic abscesses; one had previously undergone surgery for a rectal abscess. All three patients were cured of their condition by appropriate antibiotic coverage and evacuation of the abscess by needle aspiration.

Introduction norectal abscess is one of the common surgical problems of the anorectal region1-4. It is a suppurative process of the anal canal that originates from infection of an obstructed anal gland5,6. Once infection gains access to the intersphincteric space, it has easy access to the adjacent perirectal spaces7. Men are affected more than women with 3rd and 4th decades of life as the peak age of incidence7,8. In a descending order of frequency; perianal, ischiorectal, sub-mucosal and supralevator are abscess types according to anatomical location7-12. The bacterial profile of an abscess, which is usually a mixed infection involving aerobic and anaerobic microorganisms, is considered as a prognostic factor for recurrent abscess and fistula formation1,5, 7,10,13,14. Diagnosis is made on basis of history and anorectal examination and is usually easy except in case of deep abscess9,15. All cases require urgent incision and drainage4,16.

Anorectal sepsis is classified into perianal abscess which is the most common followed by Ischio Rectal Abscess. The incidence of ischio rectal abscess located around the anal canal in relation to the line joining both the ischeal tuberosity is 53% in posterior, 35% in lateral and 12% in anterior quadrant 2.

The purpose of this paper is to reemphasize that pilonidal cyst infection may result in sinuses which reach the perianal region and simulate anal fistula. Five such cases are presented for addition to the literature. Although this condition occurs infrequently, individual cases have been reported in the recent literature * in sufficient number to warrant their consideration in the differential diagnosis of anal fistula. Frequently when the secondary opening of an anal fistula is correctly located, the primary opening is either partially or completely sealed. The most valuable clinical observation in establishing the presence of an anal fistula is palpation of the tract leading from the secondary opening to the anus. This is present in the majority of cases. When no primary opening is observed and no tract palpable, the possibility of an extra-anal source of the infection must be considered. The coexistence of anal fistula and pilonidal disease has been

Postpartum pelvic hematomas, collections of blood anywhere in the pelvis between the pelvic brim and the perineum, are much more common than is evident from reports in the literature. They vary in significance from minor local vulvar and perineal hematomas that are readily visible to massive hidden retroperitoneal hematomas that may be fatal. Pain is a frequent symptom. With the vulvovaginal or vaginal hematoma, the chief complaint may be rectal pain. The proctologist should be cognizant of the entity and the similarity of its presenting symptoms to those of rectal abscess. A case of a patient who had postpartum pelvic hematoma is described. The initial symptom was severe rectal pain. The hematoma was drained by an unusual route, with a very satisfactory result.

A 60-year-old man was admitted with non-Hodgkin lymphoma, organic brain syndrome, rectal abscess, and hypotension. Two days after admission, he was comatose, and a 16 gauge central venous line was introduced. This was changed the next day to a triple-lumen catheter (fig. 1A). During the next 2 days, the catheter migrated toward the entry site (figs. 1 B and 1C). The patient died from septic shock 5 days after admission.

During the three years of its use, tolbutamide has established a remarkable record for safety. Side-reactions have been relatively few, consisting of mild gastrointestinal disturbances, skin eruptions, and mild granulocytopenias. 1 These reactions are generally not serious and disappear either after discontinuation of use of the drug or in spite of its continued administration. To date, no serious untoward reactions have been reported. Reactions, however, do occur. It should not be surprising, therefore, if an occasional case should assume grave proportions. With this thought in mind, a case is reported in which serious depression of the bone marrow was observed during the course of treatment with tolbutamide. Report of a Case A 69-year-old man was admitted to St. Vincent's Hospital on Aug. 7, 1956, with the chief complaint of weakness and collapse. The history revealed that in 1940 he was hospitalized for rectal abscess and in 1942 for cellulitis of
