[Relative contraindication of latanoprost in iris tumors with secondary glaucoma].

INTRODUCTION: Melanocytic iris tumors are often benign and merely require regular follow-up. Evident growth, increasing pigmentation and secondary glaucoma, however, are possible signs of a malignant transformation. PATIENT: We present a 34-year-old male patient showing a localized, mildly prominent hyperpigmentation of the right iris expanding over 2 h. The lesion had been known since childhood and increasing intraocular pressure (IOP) was treated with timolole, dipivefrin and finally with latanoprost. PROGRESSION: The patient was seen for the first time at our hospital 4 years previously, presenting an IOP of 28-30 mmHg of the right eye. The tumor had developed marked heterochromia and a nodular prominent surface, the chamber angle was partly closed and completely hyperpigmented. The ciliary body was not affected by the tumor and standard ultrasound revealed a maximum thickness of 1.2 mm. Over the last 4 years, IOP and heterochromia had increased but without growth of the tumor. An excisional biopsy of the prominent portion was refused by the patient. DISCUSSION: The melanocytic iris tumor described shows malignant characteristics such as progressive heterochromia and secondary glaucoma. However, increasing iris pigmentation can also be caused by topical application of latanoprost. With the evidence of absent tumor growth, there is no reason to suggest malignant degeneration. Generally, in iris naevi or tumors requiring regular follow-up, application of latanoprost should be avoided in order not to conceal the alteration of pigmentation as possible malignant conversion.

[Elective stenting of "unprotected" left main coronary stenosis in patients without contraindication to bypass surgery].

Coronary surgery is at this point of time the standard therapy of unprotected left main coronary artery stenosis. Coronary angioplasty (PTCA) is performed only in bail out situations. The number of publications of successful percutaneous intervention in unprotected left main coronary stenosis is increasing because of increasing use of stents and ticlopidine to avoid stent-thrombosis. From 9/96 to 7/98, 13 patients with unprotected left main coronary stenosis were treated with stents. All of them were accepted by the heart surgeon for bypass surgery but were not considered to be optimal candidates due to advanced age of more than 80 years (n = 5), significant co-morbidity (n = 2) or diffuse diseased peripheral coronary segments (n = 6). Mean age of patients was 74 +/- 10 years, 9 were male, and all patients presented with angina III-IV (CCS). Mean ejection fraction was 55 +/- 15%. Localization of stenoses were classified as ostial (n = 5), middle (n = 3), and bifurcational (n = 6). One patient had stenoses both in the ostium and in the bifurcation. In all cases a PTCA of the culprit stenosis was performed prior to stent implantation. The mean diameter of the stents used was 3.3 +/- 0.3 mm and the mean length was 11 +/- 4 mm. In 6 patients a PTCA of either left anterior descendens (LAD) or right coronary artery was performed in the same session. In 4 of these patients it was followed by a stent implantation. All procedures were performed with surgical stand-by, an intraaortal balloon pump was available, but was not uses prophylactically. Stent implantation could be performed successfully in 12 out of the 13 patients (success rate 92%). In bifurcational stenoses stents were positioned with the proximal end in the left main and the distal end in the LAD. Significant injury or occlusion of the circumflex artery was not observed. In one patient with bifurcational stenosis with severe calcification it was not possible to cross the lesion with an accurate sized balloon. Trying to cross with a smaller balloon (2.5 mm) resulted in dissection of the left main coronary artery which could not be reopened again by catheter technique. This patient was transferred to the operating room under conditions of cardiopulmonary resuscitation and a bypass surgery was performed. He was dismissed from the hospital with no evidence of perioperative myocardial infarction. The mean time for follow-up was 12 +/- 7 months, all patients are still alive. In 6 patients an angiography was performed during follow-up because of suspicion of recurrent ischemia. Two patients out of these 6 had restenoses in the left main coronary artery which were re-dilated (17%). Another 2 patients had stenoses in other coronary segments and were also dilated. Thus, stenting of left main coronary artery stenoses is feasible, however, with acceptable risks and could be considered in selected patients as an alternative to coronary artery surgery.

A poor response to proton pump inhibition is not a contraindication for laparoscopic antireflux surgery for gastro esophageal reflux disease.

BACKGROUND: We aimed to determine if a poor response to proton pump inhibitors (PPIs) can predict a poor outcome following laparoscopic antireflux surgery (LARS) in our surgically treated population. METHODS: A total of 324 patients undergoing LARS were included in this study. Following standardized assessment, patients recorded the efficacy of their medication on visual analogue scales. Pre- and postoperative symptom scores were recorded, with outcomes measured by modified Visick scores. RESULTS: There were 233 good responders (>50% relief) and 91 poor responders (<49% relief). Both groups demonstrated a significant decline in postoperative symptom scores. Ninety-four percent of good responders had an excellent or good outcome, compared to 87% of poor responders. Twenty-seven patients reported a fair or poor outcome, despite improved postoperative symptom scores. Fifteen of these patients reported continuing heartburn; five had positive pH tests. CONCLUSION: Our results do not support the assumption that a poor response to PPIs equates to a poor outcome after LARS.

Cirrhosis is not a contraindication to laparoscopic surgery.

BACKGROUND: Cirrhosis of the liver contributes significantly to morbidity and mortality in abdominal surgery. The proven benefits of laparoscopy seem especially applicable to patients with this complex disease. This study evaluates the safety and efficacy of laparoscopic procedures in a series of consecutively treated patients with biopsy-proven cirrhosis. METHODS: The medical records of all patients with biopsy-proven cirrhosis undergoing laparoscopic surgery at the authors' medical center between January 2000 and December 2003 were retrospectively reviewed. RESULTS: A total of 50 patients (27 men and 23 women) underwent 52 laparoscopic procedures. Among these 50 patients were 39 patients with Child-Pugh classification A cirrhosis, 10 with classification B, and 1 with classification C, who underwent a variety of laparoscopic procedures including cholecystectomy (n = 22), splenectomy (n = 18), colectomy (n = 4), diagnostic laparoscopy (n = 3), ventral hernia repair (n = 1), Nissen fundoplication (n = 1), Heller myotomy (n = 1), Roux-en-Y gastric bypass (n = 1), and radical nephrectomy (n = 1). There were two conversions (4%) to an open procedure. The mean operative time was 155 min. Estimated blood loss averaged 124 ml for all procedures, and 20 patients (40%) required perioperative transfusion of blood products. One patient required a single blood transfusion postoperatively because of anemia. No one experienced hepatic decompensation. Overall morbidity was 16%. There were no deaths. The mean length of hospitalization was 3 days. CONCLUSIONS: Although technically challenging because portal hypertension, varices, and thrombocytopenia frequently coexist, basic and advanced laparoscopic procedures are safe for patients with mild to moderate cirrhosis of the liver.

Scrotal hernias: a contraindication for an endoscopic procedure? Results of a single-institution experience in transabdominal preperitoneal repair.

INTRODUCTION: Endoscopic repair was introduced for use with inguinal hernia therapy more than 10 years ago. The technique as well as the indications for this method are debated, however. As a borderline inguinal hernia situation, the scrotal hernia in particular evokes vehement objections to an endoscopic procedure because of the anticipated problems and complications in dissecting the extended hernia sac. The efficiency of the laparoscopic transabdominal preperitoneal (TAPP) technique in the treatment of scrotal hernia therefore is discussed in this article. METHODS: Laparoscopic hernia repair (TAPP) has been performed in our department since 1993. Data are collected by a prospective documentation of operative and follow-up results. For evaluation, a comparison of scrotal and normal hernia repair was performed. RESULTS: Between April 1993 and June 1998 the TAPP technique was used to treat 191 scrotal hernias, 42 (22%) of which were recurrent hernias. The median operating time for a normal inguinal hernia repair was 45 min, whereas scrotal hernias required a median of 65 min and irreducible scrotral hernias a median of 68.5 min. Major complications were observed in 1.6% of scrotal and 0.6% of normal inguinal hernia repairs. The most frequent scrotal hernia repair problem was the formation of a seroma, 10.5% of which had to be evacuated. During a follow-up period of 30 months, we found a total of two recurrences (1.05%). CONCLUSION: In scrotal hernia repair, TAPP is not associated with higher complication rates and can be performed with efficiency comparable with that in normal inguinal hernia repair.

Cholecystoenteric fistula (CF) is not a contraindication for laparoscopic surgery.

BACKGROUND: Cholecystoenteric fistula (CF) is a rare complication of cholelithiasis. The aim of this study was to evaluate the safety and risk of complications when the laparoscopic approach is applied in patients with CF. METHODS: A questionnaire was mailed to all surgeons with experience of >100 cholecystectomies working in Naples, Italy, and the neighboring area. RESULTS: Between February 1990 and May 1999, 34 patients presented with cholecystoenteric fistula (0.2% of >15,000 laparoscopic cholecystectomies performed in the same period). These patients were allocated into two groups: the LT group (those who underwent laparotomic conversion after the diagnosis of CF), which consisted of 20 patients, four men and 16 women, with a mean age of 66.5 +/- 9.3 years (range, 46-85) and the LS group (laparoscopically treated patients), which consisted of 14 patients, three men and 11 women, with a mean age of 65.6 +/- 8.8 years (range, 51-74). They types of CF observed were as follows: in the former group of patients, cholecystoduodenal fistulas (n = 11, 55%), cholecystocolic fistulas (n = 5, 25%), cholecystojejunal fistulas (n = 3, 15%), and cholecystogastric fistulas (n = 1, 5%); in the latter group, cholecystoduodenal fistulas (n = 8, 5.1%), and cholecystocolic fistulas (n = 4, 28.6) and cholecystojejunal fistulas (n = 2, 14.3%). Stapler closure of CF was done in four LT patients and three LS patients with cholecystoduodenal fistula; it was also done in three LT patients and three LS patients with cholecystocolic fistula. Hand-sutured fistulectomy was performed in six LT patients and three LS patients with cholecystoduodenal fistula, in two LT patients with cholecystocolic fistula, and in all patients with cholecystojejunal or cholecystogastric fistula. There were no deaths or intraoperative complications in either group. One patient in the LT group developed a bronchopneumonia postoperatively. Postoperative hospital stay was significantly longer in LT patients-17 +/- 4 vs 3+/-1 days (p < 0.001). CONCLUSION: Cholecystoenteric fistula is an occasional intraoperative finding during laparoscopic cholecystectomy. The results of this study, which are based on the collective experiences of 19 surgeons, illustrate the growing success of the laparoscopic approach to this condition, including a decreasing rate of conversion to open surgery over the last 3 years.

Pulmonary hypertension is a contraindication to beta-blockade in patients with severe mitral stenosis.

Intravenous atenolol was given to 31 patients just before balloon mitral valvotomy to assess the hemodynamic efficacy and safety of beta-blockade in mitral stenosis complicated by pulmonary hypertension. Hemodynamic response in patients with pulmonary resistance > 600 dynes.sec.cm-5 (group 2, n = 17) was compared with those (group 1, n = 14) with a resistance below this value. In addition to a higher pulmonary arterial resistance (by design), patients in group 2 had a higher systemic resistance, lower cardiac index, and smaller mitral valve area compared with those in group 1. After atenolol infusion, transmitral gradient and left atrial pressure improved similarly. In spite of the decline in left atrial pressure, pulmonary vascular resistance increased in both groups, more in group 2 (847 +/- 398 dynes.sec.cm-5 to 135 +/- 648 dynes.sec.cm-5) than in group 1 (291 +/- 149 dynes.sec.cm-5 to 363 +/- 200; p < 0.001 for drug effect and p = 0.027 for group effect by two-way analysis of variance). Cardiac index declined similarly from 2.77 +/- 0.51 L/min/m2 to 2.37 +/- 0.37 L/min/m2 in group 1 and from 2.33 +/- 0.58 L/min/m2 to 1.92 +/- 0.54 L/min/m2 in group 2. Systemic pressure tended to decline only in group 2 (mean aortic pressure, 89 +/- 12 mm Hg to 89 +/- 12 mm Hg in group 1 and 90 +/- 9 mm Hg to 83 +/- 12 mm Hg in group 2; p = 0.06 for group effect).(ABSTRACT TRUNCATED AT 250 WORDS)
