Morbidity of major hepatic resections: a 100-case prospective study.

OBJECTIVE: To assess the morbidity and its main risk factors after major hepatic resection. DESIGN: Retrospective study of prospectively collected data. SETTING: University hospital, France. SUBJECTS: 100 consecutive patients who underwent major hepatic resections, 1989-95. INTERVENTIONS: Major hepatic resection, defined as resection involving 3 or more segments according to Couinaud's classification, in all cases. MAIN OUTCOME MEASURES: All complications that affected outcome or prolonged hospital stay. Risk factors identified by univariate and multivariate analysis. RESULTS: 45 patients developed at least 1 complication and 7 died. The most common complications were: pleural effusion (n = 21), hepatic failure (n = 12), and ascites (n = 9). Univariate analysis showed that the following variables were significantly related to the morbidity: age >55 years, American Society of Anesthesiologists (ASA) grade II or more, bilirubin >80 micromol/L, alkaline phosphatase activity more than double the reference range, malignant tumours, abnormal liver parenchyma, simultaneous surgical procedures, operative time >4 hours, and perioperative blood transfusion > or =600 ml. The extent of resection did not correlate with postoperative complications. Multivariate analysis showed that volume of blood transfusion > or =600 ml and simultaneous surgical procedures were the most important independent risk factors for complicated outcome. CONCLUSIONS: The morbidity associated with major hepatic resections remains high, and the main determinants of outcome are intraoperative surgeon-related factors.

Advances in general and vascular surgical care of Jehovah's Witnesses.

BACKGROUND: Jehovah's Witnesses are an enlarging religious community in the US and throughout the world. Members of this faith refuse administration of blood during medical or surgical therapy even if death may occur as a consequence. The surgeon is consequently faced with difficulties and moral dilemmas of caring for these patients. PATIENTS AND METHODS: From July 1, 1975 to March 1, 1999, the author performed 132 general and vascular surgical procedures on pediatric and adult patients who were Jehovah's Witnesses. RESULTS: A surgical series of 132 patients who are Jehovah's Witnesses is reported. The series includes general surgical procedures in children and adults. Also, vascular surgical procedures in adults are reported. Thirty-one procedures were of significant magnitude to possibly require a blood transfusion. No patient in this series received a blood transfusion. No patient was refused an indicated surgical procedure. Fourteen complications incurred in this series which included one death. The age range of patients in this surgical series was 9 months to 91 years. There was no difference in the male to female ratio. The spectrum of cases reported represents the entire range of procedures seen in general and vascular surgical practices. CONCLUSIONS: The surgical care of Jehovah's Witnesses has become less of an operative risk over the last decade. There are now significant alternatives to the transfusion of blood, such as erythropoietin, iron dextran, aprotinin and Fluosol-DA 20%. Technological surgical developments and advances, such as the cell saver, argon beam coagulator, acute limited normovolemic hemodilution, autologous whole plasma fibrin gel, and controlled hypotensive anesthesia during anesthesia have contributed substantially to a reduction in the operative loss of blood. The time honored rule of hemoglobin of 10 g/dl and a hematocrit of 30% should not require strict adherence in the postoperative care of most patients. The acceptance of a lower transfusion trigger point of hematocrit of 22% and a hemoglobin of 7 g/dl can significantly reduce transfusion requirements without an increase in morbidity. Ethical considerations are discussed and evaluated when treatment restrictions, such as blood transfusion and other life-preserving therapies are limited by religious beliefs or living wills.

Extra charge and extra length of postoperative stay attributable to surgical site infection in six selected operations.

BACKGROUND: Information concerning the economic impact of surgical site infection (SSI) is very rare in Thailand. As the national health care financial system has been changing, the need for such data is critical. OBJECTIVE: The purpose of this study is to estimate the extra charge and excess postoperative hospitalization attributable to SSI in six surgical operative procedures comprising appendectomy, herniorrhaphy, mastectomy, cholecystectomy, colectomy, and craniotomy. MATERIAL AND METHOD: The study population consisted of patients undergoing major operations admitted to Songklanagarind Hospital from January, 1998 to December, 2003. Data were prospectively collected to identify demographic data, surgical operations, development of SSI, and outcomes of SSI. The study used one-to-one matched-pair strategy to compare case (patient with SSI) and controls (patient without SSI). The matching criteria were same final diagnosis, same operative procedure, and same American Society of Anesthesiologists (ASA) score. Data were calculated for mean difference, median difference, and 95% confidence intervals (95% C.I) of hospital charge and postoperative stay. RESULTS: The study could identify 140 matched-pairs of case and control. When compared to matched controls, cases had higher hospital charge and greater postoperative length of stay. Mean of extra hospital charge attributable to SSI was 43,658 (95% C.I; 30,228-57,088) baht and mean of excess postoperative stay was 21.3 (95% C.I; 16.6-26.0) days. Median of extra expenditure was 31,140 (95% CI; 17,327-49,081) baht and median of prolongation of postoperative stay was 14 (95% C.I, 12-18) days. CONCLUSION: This study supports the findings of the previous published reports that patients who have SSI incur enormous excess cost and hospital stay.

Management of metacarpal fractures.

Fractures of the hand are the most common fractures of the human skeleton. Metacarpal fractures account for 30% to 50% of all of hand fractures. The mechanisms of these injuries vary from axial loading forces to direct blows to the dorsal hand. Resulting deformities include malrotation, angulation, and shortening. Treatment modalities vary from nonoperative reduction to open reduction and internal fixation. The treatment algorithm is guided by the location of the fracture, the stability of the fracture, and the resultant deformity. Operative procedures, although they may lead to excellent radiographic reduction of fractures, often lead to debilitating stiffness from the inflammatory reaction of the surgical procedure. Operative fixation must be employed judiciously and offered only when confident that non-operative therapy can be improved on with operative intervention. This article reviews the various types of metacarpal fractures, with the treatment options available for each fracture. The indications for each treatment modality, postoperative care, and rehabilitation are presented.

Operative ultrasound guidance for various surgical procedures.

Although percutaneous ultrasound-guided technique is currently a common practice, the use of ultrasound for the purpose of guidance during surgery has not been widely practiced. Over a period of 10 years, we performed operative ultrasonography in 2,314 operations. In 321 of these operations, operative ultrasound guidance was performed for direct assistance of various surgical procedures, particularly during operations on the brain and spinal cord, liver, pancreas, and kidney. Procedures guided by operative ultrasound were classified into the following categories: intraoperative needle placement for fluid aspiration (n = 38), agent injection (n = 14), catheter introduction (n = 27), biopsy (n = 57), surgical tissue dissection for incision (n = 48), resection (n = 82) of organs, and extraction (n = 55) of stones or foreign bodies. Operative ultrasound guidance facilitates various surgical procedures and is considered a useful modality for reducing operative complications, shortening operating time, performing otherwise impossible procedures, and, at times, developing new surgical operations.

Voice-controlled robotic arm in laparoscopic surgery.

AIM: To report on our experience with a voice-directed robotic arm for scope management in different procedures for "solo-surgery" and in complex laparoscopic operations. METHODS: A chip card with orders for the robotic arm is individually manufactured for every user. A surgeon gives order through a microphone and the optic field is thus under direct command of the surgeon. RESULTS: We analyzed 200 cases of laparoscopic procedures (gallbladder, stomach, colon, and hernia repair) done with the robotic arm. In each procedure the robotic arm worked precisely; voice understanding was exact and functioned flawlessly. A hundred "solo-surgery" operations were performed by a single surgeon. Another 96 complex videoscopic procedures were performed by a surgeon and one assistant. In comparison to other surgical procedures, operative time was not prolonged, and the number of used ports remained unchanged. CONCLUSION: Using the robotic arm in some procedures abolishes the need for assist ance. Further benefit accrued by the use of robotic assistance includes greater stability of view, less inadvertent smearing of the lens, and the absence of fatigue. The robotic arm can be used successfully in every operating theater by all surgeons using laparoscopy.
