Gastrointestinal lymphoma and sarcoma. A case for aggressive search and destroy

The incidence of sarcomas of the gastrointestinal tract has remained the same, but gastrointestinal lymphomas are gradually contributing a larger percentage of malignant gastrointestinal neoplasms. The authors have examined their more recent experience with these relatively rare lesions. Twenty-eight patients (13 with lymphoma, 15 with sarcoma) have been treated at the Vanderbilt University and the Metropolitan Nashville General Hospital since 1976. There were eight men in the group with lymphoma and six in the group with sarcoma. The average age for patients with lymphoma was 66 years; the average age was 57 years in the patients with sarcoma. Seven patients with lymphoma and eight patients with sarcoma had been treated for 6 months to 3 years for presumed peptic ulcer disease. Eight of these 15 patients were found to have perforated tumors at the time of surgical exploration. Three patients (all in the group with sarcoma) had metastatic liver disease or peritoneal implants at the time of diagnosis. Treatment for most patients included resection of the tumor, followed by chemotherapy or radiation in cases of tumor perforation or metastatic disease. The survival rate for patients with lymphoma has averaged 5.5 years, with a 55% 5-year survival rate. Patients with cleaved cell tumors survived longer than those with other types of lymphoma. In the group with sarcoma, the survival rate has been 3.1 years on the average, with a 21% 5-year survival rate.

Perforated gastric ulcers. A plea for management by primary gastric resection

One hundred one patients with perforated gastric ulcers have been treated at our institution during the past three decades. Ninety-one patients underwent operative repair, with a 24% mortality. A reduction in mortality and complications was realized when primary gastric resection, rather than patch closure, was performed. This could not be explained by selection bias, as risk factor prevalence was equally distributed between these two groups. We conclude that primary gastric resection, with or without vagotomy, is the procedure of choice for repair of perforated gastric ulcers. Only intraoperative hemodynamic instability should limit operative selection to a faster, less definitive procedure.

Surgical management of esophageal perforation

The recognition and management of esophageal perforation remain a problem. Diagnostic and treatment delays are common, and controversy continues regarding approaches to surgical intervention. Overall survival has increased with improved adjunctive modalities; however, morbidity and mortality remain high. A total of 115 consecutive cases of nonmalignant esophageal perforation were reviewed. There were 69 thoracic, 27 cervical, and 19 abdominal perforations. Etiology of the perforations was iatrogenic in 65 patients, traumatic in 28, and spontaneous perforation in 22. Symptoms included pain (71%), fever (51%), dyspnea (24%), and crepitus (22%). Contrast roentgenography was used in 78 patients and demonstrated the perforation in all but two patients. All but 20 patients had operations. In the last decade, the survival rate was 11.4 per cent for patients treated within 24 hours of perforation. Survival significantly improved in the last 10 years because of hyperalimentation, cardiopulmonary monitoring, and better antibiotic coverage. Treatment of choice is primary closure with drainage, regardless of the duration of the perforation. In selected patients who have cervical esophageal perforation, nonoperative management has a role.

Esophageal carcinoma. Improved quality of survival with resection

Twenty years ago the experience with carcinoma of the esophagus at Vanderbilt University and affiliated hospitals was reported in 263 patients. Overall 5-year survival was 2 per cent. Esophagectomy was possible in 89 patients (34%) and was associated with a 32 per cent mortality. This study updates the authors' experience with squamous cell carcinoma of the esophagus in 311 patients seen from 1966 to 1985. Overall 5-year survival has increased to 6 per cent. Esophageal resection was accomplished in 104 patients (33%), with a 10 per cent operative mortality and 41 per cent complication rate. Multi-variant analysis disclosed that smoking, alcohol use, sex, race, and site of tumor did not influence survival. Actuarial survival rates following esophageal resection were 51 per cent at 1 year, 21 per cent at 2 years, and 13 per cent at 5 years. These survival rates were not influenced by adjuvant radiotherapy. Radiation therapy was used for attempted cure in 83 patients. Actuarial survival rates following curative doses of radiation were 29 per cent at 1 year, 15 per cent at 2 years, and 4 per cent at 5 years. These survival rates were significantly (P less than 0.001) lower than survival rates following esophagectomy. The quality of life following treatment was good or fair in 83 per cent of patients undergoing esophagectomy and good or fair in 64 per cent of patients receiving "curative" doses of radiation. The results of this review demonstrate that esophageal resection using the Lewis operation or transhiatal esophagectomy can be done with an acceptable operative mortality, results in prolonged survival, and improves the quality of life.

Is ileoproctostomy a reasonable procedure after total abdominal colectomy?

A 17-year study has been made of 63 patients who had a variety of colonic disorders treated by total abdominal colectomy with ileorectal anastomosis in four hospitals affiliated with Vanderbilt University. Forty-three of these patients made an uneventful recovery, but 20 others sustained significant complications, nine of which proved to be fatal (hospital mortality rate, 14%). The study shows (and confirms the work of others) that ileorectal anastomosis after total abdominal colectomy is a reasonable procedure that provides satisfactory results on a long-term basis in a majority of patients when strict criteria in patient selection are followed in its application.

Living related kidney donors. A 14-year experience

Living related donor (LRD) nephrectomies are controversial due to the risks to the donor and improved cadaveric graft survival using cyclosporine A. Between December 22, 1970, and December 31, 1984, 1096 renal transplants were performed at a single institution, 314 (28.6%) from LRD. The average age was 34.3 years (range: 18-67); none had preoperative hypertension. All nephrectomies were performed transabdominally. Major perioperative complications occurred in 22 (7.0%). These include wound infections (3.5%), pancreatitis (1.0%), injuries to spleen (1.0%) or adrenal gland (0.3%) requiring removal, pneumonitis (0.6%), ulnar nerve palsy (0.6%), femoral artery thrombosis after arteriogram (0.3%), pulmonary embolus (0.3%), and upper pole infarct of contralateral kidney (0.3%). There are six known deaths in this series, none of which were related to the operation. Major late complications were seen in 50 (20.0%) of 250 patients followed for 6 to 175 months (mean 53.1 months). These included definite hypertension (5.6%), suture granuloma (4.4%), incisional hernia (3.6%), proteinuria (2.4%), bowel obstruction (2.0%), nephrolithiasis (1.2%), wound infection (0.4%), scrotal hydrocele (0.4%), and chronic pancreatitis (0.4%). While the risk of hypertension appears to increase as the interval from donation increases, no cases of renal failure after donation have been noted, and negligible proteinuria among those followed long-term has been seen in this series. It is felt that living related kidney donation is justified when the relative is sincerely motivated and well informed prior to donation.

Clostridial infection of renal cell carcinoma

We report a case of a large gas-filled clostridial abscess in a previously unrecognized renal cell carcinoma. Neoplastic tissue has a nonhomogeneous blood supply, creating areas of hypoxia and reduced glucose concentrations, which lead to tumor necrosis and an environment conducive to the growth of anaerobic organisms. Anaerobic infection should be considered in any patient with carcinoma and fever. Conversely, abscess transformation of a tumor can be the explanation for what otherwise seems to be the spontaneous development of a parenchymal abscess.

Surgical management of esophageal achalasia

Between 1970 and 1983, 46 patients were hospitalized in the Vanderbilt University Medical Center and the Metropolitan Nashville General Hospital for treatment of achalasia. All patients had been symptomatic for at least two years. Efforts were made initially to manage most of these patients (40) with periodic esophageal dilatation. This was successful in only six cases (15%). In four instances (10%), patients had esophageal perforation. Thirty patients have had esophagomyotomy (Heller procedure), and 14 of these had an associated antireflux procedure. Three had proximal gastric vagotomy for associated duodenal ulcer disease. Twenty-seven (90%) have had a good result, three died postoperatively, and two elderly patients had postoperative myocardial infarction. The other patient had sepsis after repair of a perforated esophagus. While periodic esophageal dilatation is necessary in patients who may not tolerate an operative procedure, most patients with achalasia are best treated with Heller esophagomyotomy.

The management of gastric ulcers. A current review

In the past 10 years, 163 patients with documented gastric ulcers were treated at Vanderbilt University and Metropolitan Nashville General Hospitals. One hundred thirty-five were initially managed medically. Medical therapy was successful in 58 patients (43%) in this group. Twenty-eight (17%) patients required surgical treatment initially. An additional 77 patients (57%) became candidates for surgical management when their medical management failed. Of this group, 40 now have been surgically treated and 37 still have symptoms while on medical treatment. Three patients being treated for benign ulcers, two for as long as six years each, were found to have carcinoma of the stomach diagnosed by subsequent endoscopy and biopsy in one and by laparotomy with gastrectomy to include the ulcer in two. We consider subtotal gastrectomy or surgical resection of the antrum, including the ulcer site, to be the preferred surgical treatment for gastric ulcers, and this was done in 50 cases. Vagotomy was done in addition to the antrectomy in 31 of these, and in addition to the subtotal resection in 11. Two patients who had vagotomy and resection subsequently developed a marginal ulcer. One of these who had a subtotal resection and vagotomy healed with medical treatment. The one who had a vagotomy and antrectomy required a second vagotomy for a missed vagus nerve. Gastrointestinal endoscopy in the past 10 years has improved to the point that very few malignant ulcers are missed by endoscopic biopsy. Large ulcers, those that perforate or continue to bleed, and those that fail to heal on medical treatment for a maximum of 2 to 3 months should be submitted to an antrectomy that includes the ulcer. Vagotomy should be added in selected cases.

Colorectal carcinoma in pregnancy

Colorectal carcinoma in pregnancy is rare. The symptoms frequently are masked by the symptoms associated with normal pregnancy, resulting in delayed diagnosis. Based on our experience with five patients and review of the literature, we developed a management regimen that takes an aggressive approach to tumor excision, yet maintains the pregnancy and fertility if possible. The prognosis is poor for most patients because the stage of the tumor is usually advanced at the time of diagnosis. The key to improved survival, as with all cancers, is early diagnosis and treatment.

Results of an aggressive surgical approach to gastric carcinoma during a twenty-three-year period

The early work of Dr. William Longmire with total gastrectomy for gastric carcinoma prompted us to initiate an aggressive surgical approach to gastric carcinoma in 1960: in curative resections radical total gastrectomy with hepaticoceliac-left gastric arterial node dissection was to be performed for tumors involving the entire stomach or upper two thirds and radical 80% to 90% subtotal gastrectomy with similar node dissection for tumors located in the antrum. During a 23-year period 213 patients with confirmed gastric carcinoma were studied. Celiotomy was performed in 192: advanced gastric cancer was found in 185 and seven had early gastric cancer. In only 80 patients could resections for "cure" be done. In 31 patients who underwent total or extended total gastrectomy the operative mortality rate was 9.6%, and life table survival curves show a better survival rate than in 49 patients treated by subtotal gastrectomy, with an operative mortality rate of 16.3%. The study shows the urgent need for diagnosis of early gastric cancer by gastroscopic screening of adults at risk and the meager salvage by radical resection in advanced disease.

Changes in surgical approach to rectal cancer

During the past 7.5 years, 87 patients treated for colorectal adenocarcinoma at levels 20 cm and below were studied. The early group was from 1975 to 1978 and the late group from 1979 to 1983, during which time the end-to-end anastomotic stapler (EEA) was available. There were 16 low anterior resections (LAR) and 16 abdominoperineal resections (APR) performed in the early group. Thirty-five patients underwent LAR, 20 APR, and 8 EEA resections in the late group. Mean tumor levels for the early group were LAR 14.2 cm and APR 8.1 cm; late group LAR 14.9 cm, APR 5.5 cm, and EEA 8.9 cm. Mean distal margins for the early group were LAR 4.7 cm, APR 8.0 cm; late group LAR 4.5 cm, APR 6.9 cm, and EEA 2.8 cm. Complication rates in the early group were LAR 19 per cent and APR 19 per cent; late group LAR 14 per cent; APR and EEA 0 per cent. Local recurrence has occurred only in the early group; LAR 12.5 per cent and APR 19 per cent. Cumulative survival for the early group is LAR 37 per cent and APR 44 per cent; late group LAR 75 per cent, APR 58 per cent, and EEA 100 per cent. Low anterior resections can be safely performed for colorectal lesions as low as 6 cm using the EEA--with smaller margins and no compromise of recurrence or survival.

Suprarenal vena caval occlusion. Principles of operative management

Retrohepatic occlusion of the inferior vena cava caused by tumor complicates complete resection and not infrequently is associated with life-threatening symptoms that accelerate the lethality of the underlying malignant process. This report summarizes our experience with caval thrombectomy and reconstruction that allowed complete removal of all gross tumor in seven patients with malignant occlusion of the retrohepatic inferior vena cava. Included in this group are five patients with renal cell carcinoma and extension of tumor into the retrohepatic vena cava. Three of these patients had extension of tumor thrombus into the right atrium. A sixth patient had recurrent right adrenal cortical carcinoma with tumor invasion of the vena cava and occlusion to the right atrium. Associated hepatic vein occlusion and secondary Budd-Chiari syndrome also was successfully managed in this patient. The final patient with occlusion of the entire suprarenal vena cava required caval reconstruction after resection of a primary leiomyosarcoma of the retrohepatic portion of the vena cava. Careful planning of the operative procedure, adequate exposure, complete mobilization of the retrohepatic vena cava, and control of the hepatic venous effluent will allow patients with retrohepatic vena caval occlusions to be managed with safety and success.

Experience with vagotomy--antrectomy and Roux-en-Y gastrojejunostomy in surgical treatment of duodenal, gastric, and stomal ulcers

Gastroduodenostomy (Billroth I) is our reconstruction of choice following gastric resection for gastroduodenal ulcer. Dissatisfaction with a Billroth II anastomosis has led us in recent years to employ a Roux-en-Y diversion in selected cases, particularly those in which the pathologic state of the pyloroduodenal canal would render a Billroth I anastomosis unsafe. During the past 7 years, truncal vagotomy-antrectomy and Roux-en-Y (VARY) has been carried out in 50 selected patients: duodenal ulcer (DU) 13 patients, gastric ulcer (GU) 11 patients, and stomal ulcer (SU) 26 patients. Fourteen patients (28%) developed postoperative complications, of which nine (18%) were of major degree and five (10%) of a lesser degree. No hospital death occurred among the 50 patients. Five patients (10%) developed postoperative delayed gastric emptying and two of the five required revision of the Roux. Forty-five patients had no clinical problems with delayed emptying. Overall results showed a Visick grading of I in 72%, Visick II in 24%, and Visick III in 4%. Further analysis revealed that of the 13 patients with DU who had VARY, 62% were Visick I, 30% Visick II, and 8% Visick III. The 11 GU patients with VARY were graded Visick I 73% and Visick II 27%. Of 26 patients with SU who underwent VARY, 77% were Visick I, 19% Visick II, and 4% Visick III. Mild to moderate dumping took place in 8% of the 50 patients, mild diarrhea 10%, weight loss 10%, and no patient experienced alkaline reflux gastritis. Long-range postoperative gastric emptying studies among nine patients using a radionuclide revealed varying patterns of emptying. Overall clinical results have been satisfactory and we are continuing to use VARY in selected cases, particularly those in which a Billroth I reconstruction appears contraindicated.

Barrett's esophagus. A surgical entity

During a ten-year period, endoscopy demonstrated acid-peptic esophagitis in 439 patients. Forty of these patients (9.1%) had Barrett's esophagus. Adenocarcinoma was present in the columnar epithelium in 15 (37.5%) of the patients with Barrett's esophagus. Hiatal hernias, with symptoms of heartburn, dysphagia, stricture, and ulceration, were found in more than 75% of the patients with Barrett's esophagus. We developed a treatment algorithm. Patients with symptomatic reflux esophagitis should undergo endoscopy with biopsy. If Barrett's esophagus is diagnosed, an antireflux procedure should be performed, preferably a proximal gastric vagotomy with Nissen's fundoplication. Follow-up examination by endoscopy with biopsy and cytology should be performed every six months. Indications for early esophagectomy include progression of cellular dysplasia, carcinoma in situ, and a non-healing Barrett's ulcer following an antireflux procedure. Our data support an aggressive surgical treatment of patients with Barrett's esophagus.

Longitudinal pancreaticojejunostomy in chronic relapsing pancreatitis with onset in childhood

Despite the rarity of chronic relapsing pancreatitis in children, in the last 15 years at Vanderbilt University Medical Center and its Children's Hospital we have used longitudinal pancreaticojejunostomy in treatment of eight patients whose symptoms began in childhood. Duration of symptoms ranged from 2 to 36 years. Seven of the eight patients had hereditary pancreatitis. Recurrent epigastric pain was characteristic and serum amylase was elevated in all patients on admission or shortly thereafter. Demonstration of an obstructed dilated pancreatic duct in all and stones in seven of eight patients by operative pancreatography in three early patients and by endoscopic retrograde cholangiopancreatography (ERCP) in five others established the therapeutic problem and facilitated treatment by removal of stones and longitudinal pancreaticojejunostomy. Results were uniformly excellent, both in the early postoperative period and in long-range follow-ups. Early diagnosis and early surgical drainage of the obstructed pancreatic duct by longitudinal pancreaticojejunostomy are desirable objectives in chronic relapsing pancreatitis with onset in childhood.

Cefoxitin versus erythromycin, neomycin, and cefazolin in colorectal operations. Importance of the duration of the surgical procedure

Perioperative parenteral cefoxitin was compared with oral erythromycin, neomycin and parenteral cefazolin in a prospective, double-blind, randomized evaluation of 119 patients undergoing colorectal operations. Patients receiving cefoxitin had a higher wound infection rate than patients receiving erythromycin-neomycin-cefazolin (12.5% v 3.2%, respectively, p = .06). A direct correlation existed between the duration of the operation and the infection rate. Cefoxitin prophylaxis was as effective as erythromycin-neomycin-cefazolin in patients undergoing surgical procedures of 4 hours or less (infection rates of 4.8% and 4.0%, respectively). However, for surgical procedures lasting more than 4 hours, 5 of 14 patients (37.5%) receiving cefoxitin developed a wound infection v 0 of 13 patients receiving erythromycin-neomycin-cefazolin (p less than .05). It is speculative as to whether frequent two-gram doses of cefoxitin given during the operation would provide prophylaxis equivalent to erythromycin-neomycin-cefazolin.

Carcinoids and the carcinoid syndrome

The many manifestations of carcinoids will continue to puzzle and intrigue surgeons. Because these are dynamic tumors which produce multiple hormones with many potential side effects, an aggressive surgical debulking of them is advocated. Even in the presence of metastatic disease, some long-term survival can be anticipated. The most debillitating aspect of this tumor to the patient is the carcinoid syndrome. The symptoms occur erratically and are often not well controlled by presently available medication. Although metastatic disease present at diagnosis is most commonly seen with jejunoileal carcinoids, colorectal carcinoids appear to be the most lethal tumors. However, they are rarely associated with the symptoms of carcinoid syndrome. Carcinoids may often be associated with other types of tumors, some of which are known to produce their own hormones. Survival of the patients seems to be related to their other tumor type rather than the primary carcinoid. The clinician should be aware of the strong association of carcinoids with peptic ulcer disease. The ulcer diathesis is probably related to ectopic histamine production and can usually be controlled by cimetidine and antacids, although surgical intervention may be required.

Crohn's disease of the esophagus

In 1932 Crohn, Ginzburg, and Oppenheimer described a distinct pathologic and clinical entity characterized by a chronic inflammatory process of unknown etiology involving the terminal ileum. Since then, Crohn's disease has been recognized in all portions of the alimentary canal from mouth to anus. Crohn's disease of the esophagus is a rare process. Such a patient is reported with a review of the literature. A review of the English literature reveals reports of 20 patients with Crohn's disease of the esophagus. One-third of these patients had regional enteritis requiring resection. Esophageal stricture, stenosis, or fistula were frequent complications requiring resection. Regional esophagitis is difficult to distinguish from carcinoma, frequently leads to esophagitis, and is associated with a higher mortality rate than Crohn's disease in other portions of the alimentary tract.

Surgical management of Crohn's disease: experience with 135 patients

Crohn's disease may involve any portion of the alimentary tract and is being seen with increasing frequency. This report details the results in 135 patients undergoing 214 operations for Crohn's disease. There were 68 males and 67 females ranging in age from 10 to 76 years. Thirty-two per cent of patients underwent multiple operations. The recurrence rate was 53 per cent, with an average follow-up of four years. The common sites of involvement by Crohn's disease were ileocolic (36%), ileum (31%), and perianal (16%). Patients were also managed for Crohn's disease of the esophagus, stomach, and duodenum. Our patient patient with Crohn's disease of the esophagus is very unique, as only 20 such cases have been reported. Primary resection of diseased bowel with re-anastomosis is the preferred operative management. A bypass procedure was done in only four patients. The mortality rate was 2.2 per cent. The incidence of carcinoma is increased in patients with small bowel regional enteritis. A recent literature review reports 36 patients with adenocarcinoma of the small bowel affected with regional enteritis. Three of the patients developed an adenocarcinoma in association with Crohn's disease.

Major hepatic resection

Among 75 major hepatic resections from 1968 to 1978, 58 were done for severe, devitalizing hepatic trauma, two thirds of which was blunt trauma. Anatomic lobectomies were done in 32 of the trauma cases. Of the 42 patients who survived, 17 had complications postoperatively. Five patients died intraoperatively of exsanguinating hemorrhage. Eleven additional patients died between days 1 and 42, four of them within two days of cardiovascular collapse. Seventeen major resections for tumor and other conditions carried a 12% mortality; four patients each had one complication postoperatively. These cases were compared with the 50 cases previously reported from this institution, totaling 125 major hepatic resections. Despite increasing severity of injury, mortality in such trauma victims has improved from 33% in the previous series to 28% in this series; it was 24% in the latter half of this series. Mortality for elective resections has improved from 23% in the earlier series to 12% in this series. Postoperative morbidity also was reduced.

Management of adult choledochal cysts

A review of the English literature reveals a total of 1,337 patients with choledochal cysts. Improved diagnostic techniques to visualize the biliary system are demonstrating an increasing number of unsuspected choledochal cysts in adult patients. Either choledochal cysts remain clinically silent until adulthood or may develop in later life. Experience is reported with adult patients having type I, II, III, and IV choledochal cysts. Type I cysts are preferably managed by excision but cyst anatomy may necessitate choledochoenteric drainage. Type II cysts are treated by excision except for those located within the pancreatic portion of the common bile duct. These are best managed by transduodenal cystoduodenostomy. The type III cyst (choledochocele) should be excised carefully, identifying and preserving the common bile and pancreatic ducts. Type IV cysts include a combination of any one of the first three types of cyst plus the presence of intrahepatic cyst or cysts. Treatment of these cysts is dictated by the type and location of the extrahepatic cyst. Since choledochal cysts are being recognized with increased frequency in adults, surgeons need to be aware of the diagnostic and treatment modalities available for each type of biliary cyst.
