The axillopectoral muscle (Langer's axillary arch): a cause of axillary vein obstruction.

The second patient recognized to have high grade intermittent obstruction of the axillary vein due to an anomalous axillopectoral muscle is reported. This relatively common anomalous muscle extends from the latissimus dorsi to the insertion of the pectoralis major and overlies the neurovascular bundle in the axilla. Preoperative recognition of this anomaly appears possible by phlebography, a history of intermittent axillary vein obstruction, loss of the normal axillary concavity, and a market disparity between obvious visual fullness in the axilla and the great difficulty encountered in palpating an axillary mass. Although a correct preoperative diagnosis of the presence of this anomaly has not been made yet, awareness of this entity is important because simple excision of this muscle is curative.

Massive rectal bleeding of colonic origin: localization of the bleeding site.

Fourteen patients with massive colonic bleeding underwent preoperative evaluation including visceral angiography and/or colonoscopy. Segmental for subtotal colectomy was performed in each case. The freshly excised colonic specimen was opened and washed clean, and the mucosal surface was closely examined by manually compressing the specimen segment by segment in order to detect the minute bleeding site(s), which were then marked with a suture for histologic sectioning. This maneuver was successful in 13 instances. In 11 of these, histologic identification was made; seven were cases of vascular malformations, and four were cases of diverticular bleeding. In 5 of these 11 cases, colonoscopy and/or visceral angiography failed to localize the bleeding sites; four were cases of bleeding of diverticular origin. Of the two patients in whom histologic identification was not made despite suture identification, one underwent a second colonic resection in which bleeding sites were histologically identified; the bleeding was not caused by vascular malformations or diverticula. The method of examining the freshly excised specimen described is useful for accurate histologic identification of the cause of colonic bleeding, particularly for diverticular bleeding. The method is also useful for immediate assessment of adequacy and appropriateness of surgical resection.

Ischemic colitis incidence following abdominal aortic reconstruction: a prospective study.

With few exceptions, the incidence of left colon ischemia following abdominal aortic reconstruction has been reported to be one to 2 percent. All reports of such ischemic events are retrospective analyses of clinically manifest or autopsy. Fifty patients were studied prospectively to determine more accurately the incidence of this complication. Aortic reconstruction was performed in 23 patients for occlusive disease (OD) and in 27 for aneurysm disease (AD). No emergency operations were performed. All patients underwent colonoscopy within 4 days of operation. Three instances of colon ischemia were noted, an incidence of 6 percent (OD 4.3 percent, AD 7.4 percent). Each patient recovered uneventfully. Two patients had diarrhea, but only after colon ischemia was recognized. Arteriographic opacification of the inferior mesenteric artery by the superior mesenteric artery collateral (meandering mesenteric artery) was documented in 35 percent of patients with OD and in 27 percent of patients with AD. Colon ischemia did not develop when this collateral was identified. The inferior mesenteric artery was patent at the aorta in all who developed colon ischema. Although clinically significant colitis following aortic reconstruction is rare, colonoscopy after operation may prove to be valuable for early recognition of ischemic changes before clinical manifestations preclude effective management.

Improved treatment of popliteal arterial injuries using anticoagulation and extra-anatomic reconstruction.

Management of popliteal arterial injuries remains a challenging problem. Early recognition and treatment, arteriography, fasciotomy, and repair of concomitant popliteal venous injuries are modalities that have contributed to improved results. Systemic heparin sodium anticoagulation and selected extra-anatomic vein graft bypass of the popliteal area are two additional measures that have contributed to a 91% success rate in treatment of popliteal arterial injuries and five of six blunt injuries were treated successfully in this time period. A limb salvage rate of only 46% was attained in the previous five-year period. There were no operative deaths. No complications attributable to systemic anticoagulation or extra-anatomic bypass graft occurred. These adjuncts are recommended to all who manage vascular injuries.

Proximal hepatic duct reconstruction. Repair using sutureless mucosal graft hepaticojejunostomy.

Six patients who had hepatic duct lesions, five who had strictures, and one who had a right hepatic duct transection underwent repair by sutureless mucosal graft hepaticojejunostomy. All patients had initial improvement, and five have maintained excellent biliary-intestinal continuity after an average 25-month follow-up. In one patient, recurrent symptoms developed and she died of cholangiocarcinoma. This technique is simple and fulfills the criteria for successful high hepatic duct reconstruction. The promising early results in these patients suggest that this procedure may provide a superior approach to this difficult problem.

Hemosuccus pancreaticus (hemoductal pancreatitis): gastrointestinal hemorrhage due to rupture of a splenic artery aneurysm into the pancreatic duct.

A patient with recurrent upper gastrointestinal bleeding was found to have pancreatitis and a pseudoaneurysm of the splenic artery that communicated with the pancreatic duct. Similar pathology noted in ten other patients found in an extensive review of the literature suggest that this rare entity must be considered in the diagnosis of gastrointestinal hemorrhage of obscure origin. In this collected experience, the combination of recurrent left upper quadrant pain, a history of pancreatitis, and recurrent bouts of gastrointestinal bleeding of obscure origin were usually present in those patients who were found to have a splenic artery aneurysm as the source of the blood loss. Distal pancreatectomy with resection of the splenic artery aneurysm is curative.

Bacterial endocarditis in the critically ill surgical patient.

The association of endocarditis with persistent intraperitoneal sepsis and right-sided heat catheterization (Swan-Ganz catheter and central venous catheter) was found in four (27%) of 15 patients with endocarditis identified at the University of Kentucky Medical Center, Lexington, during a 14-year period. These four patients had (1) intra-abdominal abscesses as a persistent source of sepsis, (2) documented septicemia, (3) long-term use of right sided heart catheters, and (4) prolonged hospitalization with a fatal outcome. In each case, endocarditis with persistent septicemia was considered a major factor contributing to a fatal outcome. Identification of a new cardiac murmur associated with septicemia was the most reliable means of diagnosis in these patients. The best form of treatment seems to be prevention by (1) eliminating septic foci, (2) using central catheters for specific indications for as short a period as possible, and (3) promptly discontinuing use of the catheter when septicemia is suspected.

Diagnostic errors with peritoneal lavage in patients with pelvic fractures.

Diagnostic peritoneal lavage, considered to be a highly accurate, technique for detecting intraperitoneal blood in the trauma patient, may be less reliable in the presence of a pelvic fracture. In a retrospective review of 222 patients with pelvic fractures, 61 patients were found who had had a diagnostic peritoneal lavage performed as part of the initial evaluation of their condition. Twenty-six of these patients had had a negative lavage result negative lavage result. There had been no false-negative results in this group, although six patients required operations for extraperitoneal injuries. Of the 35 patients with a positive lavage results, 10 (29%) were found to have false-positive lavage results with no intraperitoneal source of bleeding. The only deaths in this series occurred in the group requiring operations, eight of 41 (20%). Four of the eight detahs were due to uncontrollable bleeding that resulted from exploration of the retroperitoneal hematoma. These data suggest that a negative lavage result is highly reliable in the patient with a pelvic fracture and should allow management with confidence that there is no severe intraperitoneal injury. Positive lavage results, however, must be interpreted with caution.

A simple method to determine the resolution of operative cholangiograms.

A cholangiographic technique which facilitates visualization of the catheter itself permits the surgeon to measure the resolution of the roentgenographic technique used. When the wall of the catheter is visible, the surgeon can be confident that the resolution of the technique is in the 0.3 mm range. It is unlikely that stones greater than 0.3 mm in diameter will be missed using this technique.

Rapid totally diverting loop sigmoid colostomy with noncontaminating rectal irrigation.

Loop sigmoid colostomy employing a stapling device and catheter irrigation of the distal segment is less time-consuming and has lest potential for contamination than the standard double-barrel colostomy. Unlike the standard loop colostomy, it is totally diverting.

Hereditary polypoid diseases of the gastrointestinal tract: a working classification.

Almost all published cases of hereditary intestinal polypoid diseases can be meaningfully classified into a relatively few distinct syndromes including familial polyposis of the colon, Peutz-Jeghers syndrome, and juvenile polyposis. Familial polyposis is characterized by the development of numerous adenomatous polyps of the colon and subsequent development of colorectal carcinoma in nearly all patients. Extracolonic manifestations are common but do not influence the premalignant nature of this syndrome. Peutz-Jeghers syndrome is identifiable by a combination of circumoral melanin pigmentation and hamartomatous polyps. These polypoid lesions have an unusually wide distribution and may occur in the respiratory, gastrointestinal, or genitourinary tract. There is a small but definite increased incidence of gastrointestinal cancer in these patients. Juvenile polyposis presents a more variable spectrum. In one form there is extensive intestinal involvement leading to diarrhea, inanition, and increased susceptibility to infection. Another form is limited to the colon and easily confused with familial polyposis. With the third form, there is involvement of the stomach, intestines, and colon, which makes it easily mistaken for the Peutz-Jeghers syndrome.

Selective management of gunshot wounds to the neck. Report of a series and review of the literature.

Thirty-two patients with gunshot wounds to the neck, 13 with multiple pellet injuries and 19 with single missile injuries, were managed selectively. Although 3 of the 32 patients died in the hospital, no death was attributable to the neck injury. This experience and a review of the literature support the concept of selective management of penetrating neck injuries with intervention based on specific indications.
