The ileo neo rectal anastomosis: long-term results of surgical innovation in patients after ulcerative colitis and familial adenomatous polyposis.

PURPOSE: Restorative proctocolectomy with ileo neo rectal anastomosis (INRA) combines cure of ulcerative colitis (UC) or familial adenomatous polyposis (FAP) with restoration of intestinal continuity. Evaluation of long-term results was needed to determine if there is a place for INRA in the armamentarium of a surgeon besides the ileal pouch anal anastomosis (IPAA). METHODS: All patients with INRA were included in the analysis. Patient demographics and clinical and follow-up data (morbidity, dietary problems, defecation frequency, fecal continence, anal and neorectal physiology, and neorectal mucosa assessment) were registered prospectively. RESULTS: Seventy-nine patients were enrolled, and in 58 patients (50 UC, 8 FAP), INRA was successful. In 21 patients, intraoperative conversion to IPAA was needed. In 49 patients with INRA, a functional reservoir was achieved. No pelvic sepsis or bladder or sexual dysfunction occurred. Thirteen patients experienced episodes of reservoir inflammation. Median bowel movements of six (5, 8) with a nocturnal defecation frequency of one were recorded with fecal continence or minor incontinence. Anal manometry and neorectal physiology showed a decrease in resting pressure and an increase in squeeze pressure and maximum tolerated volume. The median follow-up was 8.1 years (6.7, 10.1). CONCLUSIONS: This is an example of a surgical innovation with a theoretical potential to be superior to the current technique. This potential was not confirmed in short- and long-term evaluations. Hence, IPAA is currently the best available alternative to a conventional ileostomy.

Autosomal dominant adult neuronal ceroid lipofuscinosis: a novel form of NCL with granular osmiophilic deposits without palmitoyl protein thioesterase 1 deficiency.

We describe the neuropathological and biochemical autopsy findings in 3 patients with autosomal dominant adult neuronal ceroid lipofuscinosis (ANCL, Parry type; MIM 162350), from a family with 6 affected individuals in 3 generations. Throughout the brain of these patients, there was abundant intraneuronal lysosomal storage of autofluorescent lipopigment granules. Striking loss of neurons in the substantia nigra was found. In contrast, little neuronal cell loss occurred in other cerebral areas, despite massive neuronal inclusions. Visceral storage was present in gut, liver, cardiomyocytes, skeletal muscle, and in the skin eccrine glands. The storage material showed highly variable immunoreactivity with antiserum against subunit c of mitochondrial ATP synthase, but uniform strong immunoreactivity for saposin D (sphingolipid activating protein D). Protein electrophoresis of isolated storage material revealed a major protein band of about 14 kDa, recognized in Western blotting by saposin D antiserum (but not subunit c of mitochondrial ATPase (SCMAS) antiserum). Electron microscopy showed ample intraneuronal granular osmiophilic deposits (GRODs), as occurs in CLN1 and congenital ovine NCL. These forms of NCL are caused by the deficiencies of palmitoyl protein thioesterase 1 and cathepsin D, respectively. However, activities of these enzymes were within normal range in our patients. Thus we propose that a gene distinct from the cathepsin D and CLN1-CLN8 genes is responsible for this autosomal dominant form of ANCL.

Autosomal dominant adult neuronal ceroid lipofuscinosis: parkinsonism due to both striatal and nigral dysfunction.

We describe a family with adult neuronal ceroid lipofuscinosis, with apparent autosomal dominant inheritance, observed in six affected individuals in three generations. Disease onset was usually in the fifth decade, but was earlier in the youngest generation. Early symptoms consisted of myoclonus in face and arms, epilepsy, auditory symptoms, cognitive decline, or depression. Parkinsonism occurred a few years after disease onset, with stooped posture, shuffling gait, bradykinesia, and mask face. Four subjects deteriorated to a state of severe handicap, with severe dementia, contractures, dysphagia, and dysarthria. Leg weakness evolved to flaccid paraparesis in two patients. Diagnosis was confirmed by brain biopsy in one patient and full autopsy in two patients. Abundant intraneuronal storage of autofluorescent material was found throughout the brain. Electron microscopy showed granular osmiophilic deposits and scarce fingerprint profiles. Striking loss of neurons in the substantia nigra pars compacta and reticulata was found. (123)I-IBZM Single photon emission computed tomography in two patients showed loss of postsynaptic D2 receptor binding in the striatum. We conclude that parkinsonism in ANCL is likely to be caused by both presynaptic nigral cell loss and postsynaptic striatal degeneration.
