First 100 cases with Doppler-guided hemorrhoidal artery ligation.

PURPOSE: This study was designed to examine the benefits of a Doppler-guided hemorrhoidal artery ligation technique in terms of surgical outcome, functional recovery, and postoperative pain. METHODS: Using local, regional, or general anesthesia, 100 patients with symptomatic Grades II or III hemorrhoids underwent sonographic identification and suture ligation of six to eight terminal branches of the superior rectal artery above the dentate line. Visual Analog Scales were used for postoperative pain scoring. Surgical and functional outcomes were assessed at 6 weeks and 3, 6, and 12 months after surgery. RESULTS: There were 42 (42 percent) males and 58 (58 percent) females (mean age, 42 years; median duration of symptoms, 6.3 years). The mean operative time was 19 minutes. Local anal block combined with intravenous sedation (n = 93) or general or spinal (n = 7) anesthesia was used. Only five were hospitalized overnight. There was no urinary retention, bleeding, or mortality in the immediate postoperative course. The mean pain score decreased from 2.1 at two hours postoperative to 1.3 on the first postoperative day. All patients had a complete functional recovery by the third postoperative day. Ninety-four patients remained asymptomatic after a mean follow-up of six months: four patients required additional surgical excision, and two required rubber band ligations for persistent bleeding. On follow-up, there was no report of incontinence to gas or feces, fecal impaction, or persistent pain. CONCLUSIONS: Our experience indicates that Doppler-guided hemorrhoidal artery ligation is safe and effective and can be performed as an outpatient procedure with local or regional anesthesia and with minimal postoperative pain and early recovery.

Bauhin's ileocecal valve syndrome-a rare cause for small-bowel obstruction: report of a case.

Benign ileocecal valve hypertrophy is a rare cause for intestinal obstruction. We describe a 51-year-old female with clinical and imaging presentation of chronic small-bowel obstruction. The patient was operated on, and a limited thickening of the ileocecal bowel wall causing intestinal obstruction was found. A right hemicolectomy was performed. On microscopic examination, severe fibrosis with hypertrophied nerves was found without any additional findings of malignancy or inflammation. Review of the relevant literature is presented.

[Review articles--to write, to read or to throw away?].

The author comments on the value of review articles, narrative and systematic, to both the reader and to the writer. Based on personal experience he advocates the publication of reviews in the local medical journal for greater impact. Review articles should not be underrated by academic institutions as they often serve as the major source of continued education to the general practitioner and to the non-academic-affiliated specialist.

[Unfinished surgery].

Appendicitis after appendectomy is rare and most often is due to incomplete appendectomy-stump appendicitis. Prophylactic appendectomy is rarely conducted as opposed to incidental appendectomy. The author focuses on the possibility of such an event by using an anecdotal case report and imagination.

Free perforation in Crohn's disease.

BACKGROUND: Free bowel perforation is one of the indications for emergency surgery in Crohn's disease. It is generally accepted that 1-3% of patients with Crohn's disease will present with a free perforation initially or eventually in their disease course. OBJECTIVES: To evaluate the incidence and treatment results of free perforation in patients with Crohn's disease and, based on our experience, to suggest recommendations. METHODS: Between 1987 and 1996, 160 patients with Crohn's disease were treated in our department and were followed for a mean period of 5 years. RESULTS: Of the 83 patients (52%) requiring surgical intervention, 13 (15.6%) were operated due to free perforation. The mean age of the perforated CD was 33 +/- 12 years and the mean duration of symptoms prior to surgery was 6 years. The location of the free perforation was the terminal ileum in 10 patients, the mid-ileum in 2 patients, and the left colon in 1 patient. Surgical treatment included 10 ileocecectomies, 2 segmental resections of small bowel, and resection of left colon with transverse colostomy and mucus fistula in one patient. There was no operative mortality. Postoperative hospital stay was 21 +/- 12 days (range 8-55 days). All patients were followed for 10-120 months (mean 58.0 +/- 36.7). Six patients (42%) required a second operation during the follow-up period. CONCLUSION: The incidence of free perforation in Crohn's disease in our experience was 15.6%. We raise the question whether surgery should be offered earlier to Crohn's disease patients in order to lower the incidence of free perforation.

Isolated rib fractures in elderly patients: mortality and morbidity.

OBJECTIVES: To describe the management, morbidity and mortality seen with isolated rib fractures in elderly patients and assess the need for hospitalization. DESIGN: A case series. SETTING: A tertiary care centre in Tel Aviv. METHODS: Hospital records of 77 elderly patients (age 65 yr and older) admitted with isolated rib fractures were reviewed over a 9-year period. MAIN OUTCOME MEASURES: Demographic, medical and hospitalization data, blood hemoglobin and oxygen saturation levels. RESULTS: The number of fractured ribs was found to correlate with the morbidity (p = 0.027) and mortality (p = 0.006). There were no significant differences in these rates with respect to comorbidity except for diabetes (higher morbidity) and congestive heart failure (higher mortality). Twenty-eight patients (36%) had pulmonary complications and 1 had cardiac complications. Pulmonary complications were fatal in 6 patients (7.8%). Multivariate analysis of the factors related to morbidity demonstrated that only oxygen saturation (p = 0.0009) and diabetes (p = 0.03) correlated significantly. CONCLUSIONS: In spite of significant morbidity and mortality in elderly patients with isolated rib fractures, prediction of the prognosis for these patients is presently not possible. Admission for observation and treatment is therefore justified and beneficial.
