This report provides our personal experience along with a general overview of the use of the circular stapler in rectal surgery. To determine the results of our experience with the use of the circular stapler for construction of anastomoses following resection, a series of 215 anastomoses performed in 214 patients was reviewed. The patients ranged in age from 33 to 88 years. There were 116 men and 98 women. Indications for operation included malignancy, diverticular disease, villous adenoma, Crohn's disease, and rectal procidentia. The types of operation performed included removal of varying portions of the large bowel. The anastomosis was performed in a uniform manner with the EEA (United States Surgical Corp., Norwalk, CT) and more recently the CEEA (United States Surgical Corp., Norwalk, CT). The operative mortality was 0.47 percent, with the death being unrelated to the anastomosis. Intraoperative complications encountered included bleeding, difficult extraction, instrument failure, incomplete doughnuts, deficient anastomoses, and miscellaneous problems. Early postoperative complications included one leak and a number of complications unrelated to the anastomoses. Anastomotic stenosis developed in 27 patients, but only 8 were permanent and only 3 of these were symptomatic. Two of these patients were treated with balloon dilatation. Anastomotic recurrences developed in 13.1 percent of patients. Our experience gained with the circular stapling device and that reported in the literature have shown it to be a reliable method of performing anastomoses to the rectum in a safe and expeditious manner.

In this paper we describe an endoscopic appearance of the sigmoid colon characterised by mucosal swelling, erythema and haemorrhage strictly localised to the crescentic mucosal folds. In a 5-year period these changes were seen in 34 (1.42%) of 2380 colonoscopies and fibreoptic sigmoidoscopies. The majority of patients were middle-aged or elderly. Diverticular disease was present in most (82%) but the abnormalities were confined to the crescentic mucosal folds with sparing of the diverticular orifices. The majority of patients presented with a history of bleeding per anum. Histologically there was a spectrum of changes varying from minor vascular congestion to florid active inflammatory disease with crypt architectural abnormalities mimicking ulcerative colitis, but rectal biopsies were invariably normal. Three patients later progressed to typical distal ulcerative colitis and two other patients presenting to us with endoscopic crescentic fold disease had a previous histologically documented history of distal ulcerative colitis. In three patients the histological features were of mucosal prolapse. About half the patients required some form of therapy to control their symptoms. Steroids and/or sulphasalazine were of value although two patients subsequently underwent sigmoid resection, one to control bleeding and the second for a diverticulosis-associated stricture. Whilst endoscopic crescentic fold disease represents a specific endoscopic appearance the clinical and histological features indicate a wide spectrum of disease.

Redundant or polypoid mucosal folds were found in eight surgically resected sigmoid colons with diverticular disease. Grossly, they were either swellings of mucosal folds or larger, leaflike, smooth-surfaced polyps with broad bases arising from mucosal folds. The number of lesions ranged from one to 11, and when multiple they formed two rows between diverticula. Swollen mucosal folds showed submucosal and mucosal vascular congestion, scanty thrombi, edema, hemorrhage, and hemosiderin deposition. Some were markedly inflamed. Polypoid lesions also showed crypt elongation and fission, upgrowth of muscle from the muscularis mucosae, and hyperplastic-metaplastic change typical of mucosal prolapse. One polyp showed evidence of an inverted diverticulum. Two cases displayed diffuse mucosal inflammation resembling inflammatory bowel disease in the region of the polyps. We speculate that these lesions result from a combination of venous congestion and mucosal redundancy secondary to spastic contraction of the muscle coat.

The presence of mucosal hyperplasia and sialomucin goblet cell secretion (transitional mucosa) was assessed in various benign, premalignant and malignant colorectal tissues. Transitional mucosa was seen in diverticular disease, solitary ulcer syndrome of the rectum, ischaemic and irradiation colitis and other diseases including pneumatosis coli, endometriosis, haemorrhoids and a colostomy margin. Adenocarcinomas had a sulphomucin or mixed secretion pattern with transitional features in the adjacent mucosa mucosa (18/27). Premalignant adenomatous polyps showed mixed secretion with transitional glands incorporated in the stalk and sometimes in the adjacent mucosa. Epithelium showing dysplasia secreted sulphomucins and in amounts related to its degree of differentiation. Transitional mucosa may not be a primary premalignant phenomemon. The conclusion and unifying concept is that it is a secondary event related to goblet cell immaturity. This can occur, secondary to proliferation in mucosal inflammation, ischaemia and prolapse or as a phenotypic expression of growth derived from underlying dysplastic epithelium.

A clinicopathological study of polypoid lesions of the lower gastrointestinal tract from 12 patients was undertaken. Clinically, the majority had signs and symptoms of rectal prolapse despite having a variety of other primary diagnoses (e.g. carcinoma of the bowel or diverticular disease). Three patients were asymptomatic. The polyps were more common in females and were usually solitary. Histologically, fibrin 'caps', fibromuscular hypertrophy and obliteration of the lamina propria, goblet cell hypertrophy and serrated tubules were consistently noted. The fibromuscular tissue often extended into the lamina propria in a radial fashion. This study shows that mucosal prolapse underpins a variety of lesions that are part of a histological spectrum of changes. Inflammatory cloacogenic polyps, inflammatory 'cap' polyps, polypoid prolapsing mucosal folds of diverticular disease and inflammatory myoglandular polyps are all due to mucosal prolapse.

We examined retrospectively 100 sigmoid colon resection specimens removed for diverticulitis (DD [diverticular disease]-diverticulitis), 53 adenocarcinoma specimens that also had diverticulosis (DD-adenocarcinoma), and 50 adenocarcinoma specimens that did not have DD (adenocarcinoma only) to study the mucosal changes that occur in DD. Documenting these histologic features could be helpful in deciphering changes seen in colonoscopic biopsy specimens from the sigmoid colon in older patients. Prominent mucosal folds were present in approximately 90% of all DD specimens. Increased mucosal lymphoplasmacytic inflammation at the bases of the prominent folds was present in 15% and 9% of DD-diverticulitis and DD-adenocarcinoma specimens, respectively. Eleven percent of the DD-diverticulitis and 4% of the DD-adenocarcinoma specimens had prolapselike mucosal abnormalities of the mucosa on the surface of the prominent mucosal folds. Mildly increased lymphoplasmacytic inflammation surrounded the diverticulosis ostia in approximately 25% of all DD specimens. All the diverticulitis ostia had neutrophilic and lymphoplasmacytic inflammation in the surrounding mucosa. No specimens had crypt distortion. Diverticular disease-related inflammation may be one cause of mild patchy inflammation that is occasionally observed in sigmoid colon biopsy specimens. Diverticular disease also should be considered as a cause of mucosal prolapse changes in sigmoid colon biopsy specimens. Other diseases should be considered when markedly increased mucosal inflammation, crypt distortion, or granulomas are present. Distinction between a DD-related incidental finding and a significant pathologic abnormality frequently can be made with the procurement of multiple biopsy specimens.

Infections are an increasing problem in the elderly population, because of the often atypical presentation and the more frequent occurrence of complications, which lead to increased morbidity and mortality. The increased prevalence of infections in the elderly is due to a number of factors: increased exposure to micro-organisms (especially in nursing homes); degeneration of various organs (atherosclerosis, pulmonary emphysema, diverticulosis, prolapse); decreased immune response; concomitant diseases (e.g. diabetes mellitus) and (or) use of medication. There is often a delay in the diagnosis because the presentation of infection in the elderly is frequently atypical and symptoms are attributed to old age, rather than to infection. Treatment may be hampered by increased resistance of micro-organisms, interaction with other drugs and toxicity problems.

A 14-year-old girl with the mitochondrial neurogastrointestinal encephalopathy syndrome had an 8-year history of intestinal pseudoobstruction with abdominal pain, persistent vomiting, gastric and duodenal dilatation, and duodenal diverticulosis. The child appeared chronically malnourished and had severe growth failure. Multisystem involvement was evident with the presence of ptosis, external ophthalmoplegia, muscle wasting, peripheral neuropathy, and diffuse white matter disease seen on magnetic resonance imaging. Lactic acidosis and increased cerebrospinal fluid protein were observed. Mitochondrial enzyme analysis of fresh-frozen skeletal muscle revealed a respiratory chain defect. Molecular genetic studies showed multiple mitochondrial DNA deletions. Pathologic findings in the intestine included atrophy of the external layer of the muscularis propria and an increased number of abnormal-appearing mitochondria in ganglion and smooth-muscle cells. Microvesicular steatosis was observed in liver, skeletal, and gastrointestinal smooth muscle, and Schwann cells of peripheral nerve. Brightly eosinophilic inclusions in the cytoplasm of gastrointestinal ganglion cells were visible by light microscopy, which were confirmed to be megamitochondria by ultrastructural studies. This is the first report of abnormal mitochondria observed in intestinal ganglion and smooth-muscle cells in this syndrome.

Diverticular colitis is the term used to describe a particular pattern of active chronic inflammation in the sigmoid colon affected by diverticular disease, namely the occurrence of luminal mucosal inflammation, whether or not there is evidence of inflammation within and/or around the diverticula themselves. The pathogenesis remains uncertain but is almost certainly multifactorial. In some cases mucosal prolapse, faecal stasis and relative mucosal ischaemia have been implicated as important pathogenetic factors, whilst other cases are clearly the result of a mass effect caused by subserosal peridiverticulitis and suppuration. Symptoms and endoscopic findings are diverse. Histologically, the disease may vary from modest inflammatory changes with vascular ectasia, through classical mucosal prolapse changes, to florid active chronic inflammation, closely mimicking chronic inflammatory bowel disease, especially ulcerative colitis. Thus, accurate clinical and endoscopic correlation is vital for the attainment of the correct diagnosis. Diverticular colitis may respond well to treatment similar to that used for chronic inflammatory bowel disease, adding to the similarities of this disease, notably localised to the sigmoid colon, and ulcerative colitis. Indeed, in a few cases described in the literature, diverticular colitis may 'progress' to otherwise classical ulcerative colitis, suggesting, in some cases at least, a similar pathogenesis.

Different reconstructive operations were performed in 20 patients for intraoperative traumas of the urinary tract. 4 patients had injured ureter and urinary bladder. The damage was done in the course of obstetric operations (cesarean section, uterine extirpation). In 12 cases the ureter was injured in uterine extirpation for cancer (n = 4), myoma (n = 4), prolapse of the uterus, (n = 1), extirpation of uterine cervix stump (n = 1), ureteral electrocoagulation (n = 1) and adnexectomy (n = 1). In 4 cases ligation of the ureter complicated surgical interventions for cancer of the sigmoid colon (n = 1) and rectum (n = 1), diverticulosis of the colon (n = 1) and portal cirrhosis of the liver with evident cirrhosis (n = 1). Surgical policy in the treatment of intraoperative urinary tract injuries was organ-saving. Only in 3 patients with severe acute pyelonephritis surgery was two-staged with prior nephrostomy. In the rest cases primary reconstructive operations were made. Two patients with bilateral injury of the ureters after uterine extirpation have undergone transabdominal bilateral reimplantation of the ureters by Boari in Gregoir's modification. Reconstruction of pelvic ureter was often made by using a urinary bladder graft (Boari's technique). In 1 female patient with extensive vesicovaginal fistula resultant in detruzor corrugation sigmocystoplasty was made with a good result. Serious complications after the reconstruction were absent. Urinary fistulas formed in 4 cases. In 3 of them they closed without surgical intervention. In 1 patient, to close urinary fistula complicating ureterocystoanastomosis Boari's operation was conducted with a favourable outcome. Reconstructive operations saved the kidney function.
