Surgical approach to short-bowel syndrome. Experience in a population of 160 patients.

OBJECTIVE: The authors reviewed their experience with short-bowel syndrome to define the surgical approach to this problem in 160 patients. METHODS: Forty-eight adults and 112 children were evaluated over a 15-year period. RESULTS: Seventy-one patients (44%) adapted to resection and took enteral nutrition alone. Forty-four patients (28%) were supported by parenteral nutrition (PN). Forty-five patients (28%) have had 49 surgical procedures. Fifteen patients with adequate intestinal length (> 120 cm in adults) but dilated dysfunctional bowel underwent stricturoplasty (n = 4) or tapering (n = 11). Thirteen patients (87%) demonstrated clinical improvement. Fourteen patients with shorter remnants (90-120 cm) and rapid transit time received an artificial valve (n = 2) or a reversed segment (n = 1). All patients' conditions improved initially, but the reversed segment was revised or taken down. Fourteen patients with short remnants and dilated bowel underwent intestinal lengthening. Twelve patients' conditions improved (86%), one underwent transplantation, and one died. Sixteen patients with very short remnants (< 60 cm) and complications of PN underwent solitary intestine (n = 4) or combined liver-intestinal transplantation (n = 13). One-year graft survival was 65%. There have been five deaths. CONCLUSIONS: The surgical approach to short-bowel syndrome depends on the patient's age, remnant length and caliber, intestinal function, and PN-related complications. Nontransplant procedures have a role in the treatment of selected patients. Intestinal transplantation is emerging as a potential therapy for patients with significant PN-related complications.

Short bowel syndrome.

With utilization of the techniques discussed in this review, patients with short bowel syndrome can be expected to live prolonged lives, even after fairly massive resection. Advances in parenteral and home parenteral nutrition and changes in the long-term management of chronic complications have altered the lifestyles of patients with short bowel syndrome. Intestinal transplantation may become an effective mode of therapy within a short period of time. Many surgeons faced with the possibility of leaving a child with only 10-15 cm of bowel in the past have closed the abdomen with the dead bowel and let the child die. These recent advances raise interesting ethical dilemmas. Research into the process of intestinal adaptation as well as greater experience with intestinal transplantation and other modes of therapy may further improve prognosis.

Experience with intestinal lengthening for the short-bowel syndrome.

Patients with the short-bowel syndrome frequently develop dilated intestinal segments that may lead to impaired motility and malabsorption. Although intestinal tapering alone improves motility, the intestine can be lengthened as well. We reviewed our experience with six children undergoing intestinal lengthening to improve intestinal absorption secondary to the short-bowel syndrome. The procedure was performed by dissecting the vessels along the mesenteric border and dividing the intestine longitudinally with a stapler. Five patients were receiving total parenteral nutrition (TPN) and one was becoming malnourished with enteral feedings alone. Bacterial overgrowth was documented in four patients and abnormal liver function in three patients. The intestinal segments were dilated up to 10 cm in diameter and remnant length ranged from 15 to 79 cm. Segments 5 to 25 cm in length were divided, resulting in an average increase in length of 52%. Necrosis of one of the divided limbs necessitated resection in one patient. Follow-up ranged from 2 to 84 months. TPN has been discontinued in four patients and avoided in another. Symptomatic improvement occurred in all patients. We feel the tapering and lengthening procedure should be considered in patients with symptomatic, dilated intestinal segments in whom the need for TPN may potentially be obviated.

Unusual manifestations of neonatal pharyngeal perforation.

The small series of previously described cases of neonatal pharyngeal perforation are reviewed and two additional cases with atypical initial presentations are described. The condition is more common than is currently appreciated, as suggested by one of our cases which remained undetected until many years later. We also wish to emphasise the high location of perforation despite an initial presentation which may appear to the contrary.

Heparin-induced spinal fractures.

A 27-year-old woman received heparin sodium for 152 days because of antepartum iliofemoral thrombophlebitis. At the end of this time, spinal osteoporosis and multiple vertebral fractures became clinically evident and were attributed to the prolonged administration of heparin. Previously reported cases of "heparin osteoporosis" were reviewed. The significance of the daily dose of heparin and the duration of therapy are reemphasized. This therapeutic complication and the management of antepartum iliofemoral thrombophlebitis are discussed. Prolonged administration of heparin in daily doses exceeding 10,000 units is potentially hazardous.

The morbidity of vasectomy.

Elective bilateral vasectomy has become an established surgical procedure to achieve sterilization in the male. The ability to accomplish this by an ambulatory technique, with few side-effects, probably accounts for the widespread demand by the general public. However, a number of significant complications were encountered in a series of 250 patients who were carefully surveyed to determine the actual morbidity of this operation. In addition, five patients exhibited spontaneous regeneration of the severed vas deferens, one instance having been documented as occurring after the absence of spermatozoa from the ejaculate. These difficulties must be emphasized in preoperative discussions with patients seeking this method of contraception.
