Diverticular disease, and particularly diverticulitis, has an increasing incidence in Westernized countries because of low-fiber diet. Diverticular disease may be classified as asymptomatic, atypical, acute or uncomplicated, and complicated. Conservative or medical management is usually indicated for acute or uncomplicated diverticulitis, with elective surgical resection generally being recommended after two documented episodes. Complicated diverticulitis, because of the high rate of recurrent problems, is generally managed promptly with sigmoid resection. Sigmoid resection for diverticulitis, under appropriate circumstances, has one of the highest success rates of any of the common gastrointestinal procedures.

BACKGROUND: Excessive perioperative fluid administration likely increases postoperative cardiovascular, infectious, and GI complications. Early administration of diuretics after elective surgery facilitates rapid mobilization of excess fluid, potentially leading to decreased bowel edema, more rapid return of bowel function, and reduced length of hospital stay. OBJECTIVE: This study aimed to evaluate the benefit of early diuresis after elective colon and rectal surgery in the setting of an enhanced recovery after surgery practice. DESIGN: This was a prospective study. SETTINGS: The study was conducted at a quaternary referral center. PATIENTS: A randomized, open-label, parallel-group trial was conducted in patients undergoing elective colon and rectal surgery at a single quaternary referral center. INTERVENTION: The primary intervention was administration of intravenous furosemide plus enhanced recovery after surgery on postoperative day 1 and 2 versus enhanced recovery after surgery alone. MAIN OUTCOME MEASURES: The primary outcome was length of hospital stay. Secondary outcomes included 30-day readmission rate, time to stool output during hospitalization after surgery, and incidence of various complications within the first 48 hours of hospital stay. RESULTS: In total, 123 patients were randomly assigned to receive either furosemide plus enhanced recovery after surgery (n = 62) or enhanced recovery after surgery alone (n = 61). Groups were evenly matched at baseline. At interim analysis, length of hospital stay was not superior in the intervention group (80.6 vs 99.6 hours, p = 0.564). No significant difference was identified in the rates of nasogastric tube replacement (1.6% vs 9.7%, p = 0.125). Time to return of bowel function was significantly longer in the intervention group (45.4 vs 48.8 hours, p = 0.048). The decision was made to end the study early because the conditional power of the study favored futility. LIMITATIONS: This was a single-center study. CONCLUSIONS: Early administration of furosemide does not significantly reduce the length of hospital stay after elective colon and rectal surgery in the setting of enhanced recovery after surgery practice.

AbstractApproximately 5% of rectal cancers are locally advanced with adherence to the vagina, uterus, bladder, prostate, or other structures. Sacral involvement is fortunately rare in primary cancers. In about 50% of patients there is histologic confirmation of tumor invasion in the area of adherence. It is important to recognize the nature of these tumors pre‐operatively so that the patient can be prepared for an exenterative procedure should this be necessary. When these tumors are removeden bloc, 5‐year survival rates of 50% can be obtained with survival depending on the presence or absence of regional metastasis and also the presence or absence of histologic tumor invasion into adjacent structures.

AbstractAt the Mayo Clinic, 103 patients with primary malignant lymphoma of the thyroid have been diagnosed and treated through 1978. This study examines the clinical findings in the 57 new cases seen since the last review in 1966; pathology and survival are evaluated for the series as a whole, including the 46 patients reported previously. Age and sex patterns were unchanged since the earlier review; thyroid lymphoma tended to occur in middle‐ to older‐aged women, and patients typically presented with a fairly rapidly enlarging, painless, and firm thyroid mass. The most common histologic subtype of lymphoma encountered was diffuse large cell (diffuse histiocytic). Hashimoto's disease was found in 36% of the pathologic specimens available for review. Follow‐up was completed for all patients up to 1979. Age, sex, and histologic subtype of tumor did not appear to be significant determinants of prognosis. Patients in whom the lymphoma was confined to the thyroid (intrathyroidal type) had a better overall 5‐year survival rate (86%) than those in whom tumor invaded soft tissues surrounding the hyroid or involved regional cervical nodes (38% for the extrathyroidal type). Almost all of the patients who had intrathyroidal tumors underwent surgical resection before irradiation. However, 3 of the 5 patients in this group who were treated by radiotherapy alone survived more than 5 years. There were approximately equal numbers of patients with the extrathyroidal type of lymphoma who were treated either by radiotherapy combined with surgical resection or by radiotherapy alone. The one form of therapy was just as effective as the other.
