Single-layer continuous suture for gastrojejunostomy.

A variety of techniques are available for the construction of a gastrojejunostomy. Little information is available regarding the influence of anastomotic technique on functional outcome, particularly delayed gastric emptying and other postgastrectomy syndromes. Twenty-seven cases were reviewed in which single-layer continuous suture was used for gastrojejunostomy. Most patients underwent pancreatoduodenectomy, subtotal gastrectomy, or gastrojejunal bypass for malignant obstruction. There were no anastomotic leaks. A regular diet was tolerated at a median of 6 days. There were no cases of delayed gastric emptying, and follow-up to date demonstrates a low incidence of postgastrectomy morbidity.

Cancer of the esophagus following allogeneic bone marrow transplantation for acute leukemia.

The successful development of allogeneic bone marrow transplantation (BMT) has markedly improved the treatment results for acute leukemia and other hematologic diseases. However, significant complications are associated with this procedure including the development of chronic graft versus host disease (GVHD). Treatment for this condition requires chronic immunosuppression which can lead to the development of second cancers. It is well known that immunosuppression is associated with a variety of tumors, most commonly lymphoma. The development of solid tumors appears to be less common but follow-up studies of patients treated for Hodgkin's disease demonstrate a rising incidence of solid tumor development after a delay of 5 to 10 years. We describe a patient recently treated for a squamous cell carcinoma of the esophagus which developed 5 years after an allogeneic BMT for acute myelogenous leukemia (AML). The patient had been treated with immunosuppressants for chronic GVHD. The clinical course is described and the literature is reviewed regarding recent experience with the development of solid tumors following allogeneic BMT. The majority of second tumors following BMT are lymphomas and leukemias. Secondary solid tumors are less common, but the incidence appears to increase over time. Squamous carcinomas are most common and a preparative regimen combining radiation and chemotherapy may increase risk. Careful long-term follow-up of BMT is essential in order to detect second tumors at an early stage.

Total pelvic exenteration with preservation of fecal continence.

Total pelvic exenteration may be required in the management of locally advanced or recurrent pelvic malignancy. Although prolonged survival may be achieved, the morbidity of this procedure is substantial. Many of the complications associated with total pelvic exenteration are related to the perineal wound, the necessity for two cutaneous stomas, and the creation of a empty pelvis that often has been previously irradiated. In selected cases, perineal preservation with restoration of coloanal continuity may significantly reduce postoperative morbidity. We report four cases of recurrent pelvic malignancy treated by total pelvic exenteration with preservation of fecal continence.

Tendosynovial sarcoma. Clinicopathologic features, treatment, and prognosis.

BACKGROUND: Clinicopathologic features, treatment, and results are reported for 95 tendosynovial sarcomas identified from a prospective sarcoma data base established at Memorial Sloan-Kettering Cancer Center (MSKCC) in 1982. METHODS: Eighty-five patients had definitive treatment of the primary tumor at MSKCC: Epithelial sarcomas were excluded. RESULTS: The local recurrence rate was 18%. Survival rates were not influenced by either the method of local treatment or the use of chemotherapy. The overall actuarial survival rate was 59% at 5 years (median, 92 months). For 25 patients who had resection of pulmonary metastases, the 5-year actuarial survival rate was 43% (median, 22 months) from the time of first thoracotomy. Sex, age, tumor site, and histologic subtype (monophasic versus biphasic) were not significant predictors of survival rates. Regional lymph node metastasis occurred in 3%. The incidence of distant metastasis was 49%, with an associated 5-year survival rate of 31% (median, 33 months). Tumor size was a highly significant prognostic feature, with 5-year survival rates of 86% for patients with tumors smaller than 5 cm and 22% for those with tumors larger than 10 cm (P less than 0.00001). CONCLUSIONS: Improvement of treatment results for tendosynovial sarcoma will require effective new systemic adjuvant therapeutic strategies.

Variables correlated with the risk of lymph node metastasis in early rectal cancer.

To ascertain the risk of lymph node metastasis (LNM) from early rectal cancer, the authors retrospectively analyzed 154 patients with pT1 or pT2 rectal cancer treated by radical resection. Gross and microscopic pathologic characteristics of the primary tumor were examined as predictors of LNM. Comparisons were done by Fisher's test; significance was defined as a P value of less than 0.05. The incidence of LNM for T1 and T2 tumors was 3 of 26 (12%) and 28 of 128 (22%), respectively. LNM occurred significantly less often in well-differentiated cancers (0 of 12.0%). The incidence of LNM for T1/T2 tumors without lymphatic vessel invasion (LVI) or blood vessel invasion (BVI) (20 of 119, 17%) was significantly less than that for T1/T2 tumors with LVI or BVI (10 of 32, 31%). None of the T1 tumors without LVI or BVI had LNM. There was a trend toward decreased LNM for sessile nonulcerated tumors compared with nonpolypoid, exophytic, or ulcerated lesions (P = 0.06). Tumor size and colloid histologic characteristics were not significant predictive features for LNM. The data suggest that local excision alone is adequate for well-differentiated or moderately differentiated T1 rectal cancer in the absence of LVI or BVI and for well-differentiated T2 tumors. Radical resection or local excision combined with pelvic radiation therapy may be more appropriate for the remainder of early cancers.

Desmoid tumors of the chest wall. A locally recurrent problem.

Desmoid tumors, in general, are known for their propensity to recur. To evaluate treatment and results, we reviewed the records of 32 patients admitted to our institution with a chest wall desmoid tumor from 1948 to 1988. There were 13 men and 19 women whose ages ranged from 12 to 67 years (median 36 years). Four patients had Gardner's syndrome. Treatment was wide resection. Median follow-up was 110 months. The overall 5-year survival was 93%; 5-year disease-free survival was 71%. The 5-year local recurrence rate was 29%. Since death from disease is uncommon after resection, but local recurrence is common, we recommend aggressive wide resection in patients who have desmoid tumors of the chest wall when seen initially.

Arterial hemorrhage after pancreatoduodenectomy. The 'sentinel bleed'.

Experienced centers report reduced operative mortality after pancreatoduodenectomy for cancer, but significant complications continue to occur in as many as 25% of patients. Anastomotic disruption leads to sepsis in the pancreatic bed where major vascular structures have been exposed by regional lymphadenectomy, creating a setting for arterial erosion or ligature slough and massive hemorrhage. Dehiscence of the pancreatojejunostomy is a particular risk. We treated five patients with arterial hemorrhage after pancreatoduodenectomy, all of whom had had "sentinel" bleeding from the abdominal drains or gastrointestinal tract. Results of endoscopy were misleading in two patients. Three of five patients were saved by prompt recognition, early operation, and, in one instance, angiographic embolization. Sentinel bleeding after pancreatoduodenectomy indicates local sepsis and probable anastomotic dehiscence. Recognition of its significance and prompt response may prevent exsanguination.

Peritoneal seeding following potentially curative resection of colonic carcinoma: implications for adjuvant therapy.

Adjuvant therapeutic strategies for colon cancer are based on the knowledge of tumor recurrence patterns following potentially curative resection. Innovative methods for regional delivery of chemotherapy to the liver and peritoneal surfaces are now available to complement systemic treatment. We reviewed clinical, reoperation, and autopsy series to determine the incidence of peritoneal seeding following colon cancer resection. The data suggest a 25-35 percent peritoneal failure rate among patients that recur, indicating that intraperitoneal chemotherapy is a sensible adjuvant approach. The theory behind intraperitoneal chemotherapy and potential complications is discussed. We suggest initiation of clinical trials combining systemic and intraperitoneal chemotherapy.
