Superior mesenteric arterial occlusion from a leiomyoma.

We report a solitary leiomyoma of the superior mesenteric artery resulting in arterial occlusion and gangrenous bowel. On histologic evaluation the lesion extended into the vessel lumen off its stalk and showed immunostaining for smooth muscle antigen and desmin. Leiomyomas can arise anywhere there is smooth muscle and occur most commonly in the uterus followed by the skin and gastrointestinal tract. We could not identify any previous case in the literature of a leiomyoma arising from within the wall of a mesenteric vessel.

A survey of preferred approach to inguinal hernia repair: laparoscopic or inguinal incision?

The recent interest in laparoscopic surgery has raised some concerns that large numbers of surgeons were recommending this "minimally invasive" approach in procedures such as inguinal herniorrhaphy before the availability of adequate data regarding safety and benefits. To determine current experience and preference levels for laparoscopic inguinal herniorrhaphy (LH), we conducted a mail survey of New Jersey surgeons. Of 531 respondents, 430 (81%) preferred a traditional inguinal incision approach over a laparoscopic approach (8%). Of 344 general surgeon respondents, 227 (66%) had experience with laparoscopic cholecystectomy, but only 56 (16%) had experience with LH. This latter group had performed only an average of 9.2 laparoscopic herniorrhaphies, with a median of five cases. Most of these 56 surgeons with LH experience indicated a preference for inguinal incision herniorrhaphy although 19 surgeons who had performed 10 or more LH cases showed a slight preference for LH (11 to 8). The primary reasons for choosing LH included "less pain" and "quicker recovery." The primary reasons for choosing inguinal incision herniorrhaphy included having a "better known procedure" and avoiding general anesthesia. Our survey indicates that the laparoscopic approach to inguinal hernia repair has currently accumulated few proponents in the surgical community since many surgeons are waiting for more data on the procedure.

Pancreaticoduodenectomy without homologous blood transfusion in an anemic Jehovah's Witness.

Whipple pancreaticoduodenectomy is an accepted procedure for management of periampullary and pancreatic carcinomas and has modern mortality rates of less than 10%. The procedure is associated with significant operative blood loss. Therefore, blood transfusion is an important supportive measure. We report the case of a bleeding ampullary carcinoma in a Jehovah's Witness who refused transfusion of all homologous blood products. Despite a preoperative hemoglobin level of 51 g/L, curative pancreaticoduodenectomy was successfully performed. The success of the procedure can be primarily attributed to careful surgical technique, intraoperative autotransfusion, avoidance of postoperative complications, minimization of perioperative phlebotomies, use of human recombinant erythropoietin, and, possibly, the use of the perfluorocarbon emulsion Fluosol DA-20%. The case illustrates several important principles for the surgical treatment of patients with severe anemia who refuse transfusion of homologous blood products.

Elective surgery without transfusion: influence of preoperative hemoglobin level and blood loss on mortality.

To clarify the widespread practice of preoperative transfusion to attain a 10 g/dL level of hemoglobin, the relationship between preoperative hemoglobin level, operative blood loss, and mortality was studied by analyzing the results of 113 operations in 107 consecutive Jehovah's Witness patients who underwent major elective surgery. Ninety-three patients had preoperative hemoglobin values greater than 10 g/dL; 20 had preoperative hemoglobin levels between 6 to 10 g/dL. Mortality for preoperative hemoglobin levels greater than 10 g/dL was 3 of 93 (3.2%); for preoperative hemoglobin levels between 6 to 10 g/dL, mortality was 1 of 20 (5%). Mortality was significantly increased with an estimated blood loss of greater than 500 mL, regardless of the preoperative hemoglobin level (p less than 0.025). More importantly, there was no mortality if estimated blood loss was less than 500 mL, regardless of the preoperative hemoglobin level. From these data, we conclude that: (1) Mortality in elective surgery appears to depend more on estimated blood loss than on preoperative hemoglobin levels; and (2) Elective surgery can be done safely in patients with a preoperative hemoglobin level as low as 6 g/dL if estimated blood loss is kept below 500 mL.

A comparison of laparoscopic and open appendectomy.

BACKGROUND AND OBJECTIVES: To compare laparoscopic appendectomy with traditional open appendectomy. METHODS: Seventy-one patients requiring operative intervention for suspected acute appendicitis were prospectively compared. Thirty-seven patients underwent laparoscopic appendectomy, and 34 had open appendectomy through a right lower quadrant incision. Length of surgery, postoperative morbidity and length of postoperative stay (LOS) were recorded. Both groups were similar with regard to age, gender, height, weight, fever, leukocytosis, and incidence of normal vs. gangrenous or perforated appendix. RESULTS: Mean LOS was significantly shorter for patients with acute suppurative appendicitis who underwent laparoscopic appendectomy (2.5 days vs. 4.0 days, p < 0.01). Mean LOS was no different when patients classified as having gangrenous or perforated appendicitis were included in the analysis (3.7 days vs. 4.1 days, P = 0.11). The laparoscopy group had significantly longer surgery times (72 min vs. 58 min, p < 0.001). There was no significant difference in the incidence of postoperative morbidity. CONCLUSIONS: Laparoscopic appendectomy reduces LOS as compared with the traditional open technique in patients with acute suppurative appendicitis. The longer operative time for the laparoscopic approach in our study is likely related to the learning curve associated with the procedure and did not increase morbidity.
