Laparoscopic cholecystectomy vs open cholecystectomy in the treatment of acute cholecystitis: a prospective study.

OBJECTIVE: To compare the results of laparoscopic cholecystectomy (LC) with those of open cholecystectomy (OC) in the treatment of acute cholecystitis. DESIGN: A prospective, nonrandomized trial. SETTING: "Virgen de la Arrixaca" University Hospital, El Palmar (Murcia), Spain. PATIENTS: One hundred fourteen patients underwent LC, and 110 underwent OC. The patients underwent surgery within 72 hours of the onset of symptoms. The patients were selected for LC or OC depending on the surgeon's experience in laparoscopic surgery. MAIN OUTCOME MEASURES: Operating time, rate of conversion from LC to OC, complications, and length of hospital stay. RESULTS: Conversion from LC to OC was necessary in 15% of the patients. The mean operating time was 77 minutes for the OC group and 88 minutes for the LC group (P<.001). Complications occurred in 14% of the patients in the LC group and in 23% of the patients in the OC group, with no significant differences between the 2 groups (P=.06). The number of moderate or severe complications was similar in both groups, whereas mild complications were more common in the OC group (P<.02). The length of the hospital stay averaged 8.1 days for the OC group and 3.3 days for the LC group (P<.001). CONCLUSIONS: Laparoscopic cholecystectomy is a safe, valid alternative to OC in patients with acute cholecystitis. The technique has a low rate of complications, implies a shorter hospital stay, and offers the patient a more comfortable postoperative period than OC.

Subtotal colectomy vs. intraoperative colonic irrigation in the management of obstructed left colon carcinoma.

PURPOSE: Whether primary anastomosis should be performed after segmental resection with intraoperative colonic irrigation or subtotal colectomy is not yet established in the surgical treatment of obstructive left colon carcinoma. In this prospective, nonrandomized study, we present the results of 66 patients undergoing one-stage surgery for obstructed left colon carcinoma. PATIENTS AND METHODS: We compared two techniques, subtotal colectomy (35 patients) and intraoperative colonic irrigation with segmental resection and immediate anastomosis (31 patients). RESULTS: The mortality rate was similar in both groups, 8.5 percent in the subtotal colectomy group and 3.2 percent in the intraoperative colonic irrigation group. The surgical complication rate was significantly higher in the intraoperative colonic irrigation group (41.9 percent) than in the subtotal colectomy group (14.2 percent; P < 0.05). Mean operating time was significantly lower in the subtotal colectomy group than in the intraoperative colonic irrigation group (P < 0.05). Both groups had a similar mean duration of hospital stay. Ten patients who underwent subtotal colectomy (31.2 percent) presented with diarrhea in the immediate postoperative period, which disappeared spontaneously or with antidiarrheal medication; a disabling diarrhea persisted in two patients only (6.2 percent). CONCLUSION: We believe that subtotal colectomy is the treatment of choice for obstructed left-sided colonic carcinoma. Segmental resection with intraoperative colonic irrigation is more appropriate than subtotal colectomy only in patients with carcinomas of the rectosigmoid junction or with previous anal incontinence to avoid the appearance of postoperative diarrhea.

Laparoscopic vs. open cholecystectomy in patients aged 65 and older.

Laparoscopic cholecystectomy (LC) has displaced open cholecystectomy (OC) in the management of cholelithiasis. However, there are few studies on the role of this technique in patients who run a high risk of surgical complications. We performed a prospective study in 264 patients aged >65 years undergoing surgery for symptomatic cholelithiasis. They were divided into two groups according to the surgical technique performed: OC (131 patients) and LC (133 patients). Conversion from LC to OC was necessary in 11 patients (8.3%). Mean surgery time was 70.9 min for the OC group and 75 min for the LC group. The LC group had a lower rate of postoperative complications (13.53%) than the OC group (23.6%). The incidence of mild complications was similar in both groups; however, the rate of moderate complications was significantly higher in the OC group. Hospital stay was significantly longer in the OC group (9.9 days) than in the LC group (3.71 days). These results suggest that LC should be indicated in elderly patients, as they are better than those obtained with with OC and involve a lower morbidity rate and shorter hospital stay.

Thoracoscopic partial pericardiectomy in the diagnosis and management of pericardial effusion.

BACKGROUND: An effort was made to present our experience with thoracoscopy in the diagnosis and management of pericardial effusions. METHODS: Twenty-two partial pericardiectomies were performed with the thoracoscopic approach in patients with pericardial effusions, the etiology of which was uremic (n = 7), neoplastic (n = 8), idiopathic (n = 5), septicemia (n = 1), and postpericardiotomy (n = 1). All cases had grade III-IV/IV radiological cardiomegaly and ultrasonographic confirmation of the effusion. We found hemodynamic compromise in 17 patients. The operation, requiring the insertion of three trocars, enabled us to remove a large part (approximately 6 x 10 cm) of the left anterolateral side of the pericardium and aspirate the effusion contents for diagnostic and therapeutic purposes. RESULTS: In five cases we found coexisting pleural effusions. The pericardial effusion had a mean volume of 817 ml, which was serous in 11 cases, hematic in six, serohematic in four, and purulent in one. Cytology of the pericardial effusion was positive for neoplasia in four cases (one pulmonary neoplasia, two breast carcinomas, and one lymphoma). We observed conversion to grade I/IV cardiomegaly in 16 cases and a return to normality in the other six, with the absence of ultrasonographic effusion in all cases. There was no recurrence during the mean follow-up period of 20.5 months (range: 2-47). CONCLUSIONS: The thoracoscopic management of pericardial effusions is a simple and effective technique that allows us to create a large pericardial window that drains the effusion definitively, determines its etiology, and explores and treats coexisting pleural lesions, all without recurrences.

Laparoscopic cholecystectomy in the treatment of acute cholecystitis.

BACKGROUND: Laparoscopic cholecystectomy has several advantages over traditional cholecystectomy, which make it the treatment of choice for patients with uncomplicated biliary lithiasis. However, in patients with acute cholecystitis, the role of this technique remains controversial and some clinicians regard this condition as a contraindication to laparoscopic cholecystectomy. STUDY DESIGN: Between June, 1991 and July, 1993, a total of 259 patients with cholelithiasis underwent laparoscopic cholecystectomy at the "Virgen de la Arrixaca" University Hospital. Of these patients, 60 underwent laparoscopic cholecystectomy for acute cholecystitis. RESULTS: Conversion to laparotomy was necessary in eight patients (13 percent). Mean operating time was 83 minutes (range, 45 to 180 minutes). Overall mean hospital stay (laparoscopy and conversions) was 3.1 days (range, one to nine days). There was no mortality or injury to the common bile duct in our series. CONCLUSIONS: We believe that laparoscopic cholecystectomy in patients with acute cholecystitis is a safe and effective procedure, in which the patient can benefit from the advantages of laparoscopic surgery without an increase in mortality and morbidity rates.

Gastrointestinal bezoars.

Of 99 patients with 117 gastrointestinal bezoars, 69 had undergone previous surgery, the most common operation being bilateral truncal vagotomy with pyloroplasty (55 patients). An excessive intake of vegetable fibre was found in 38 patients and poor mastication in 27. Thirty bezoars presented with gastric symptoms and patients had endoscopy as the diagnostic technique; 87 caused symptoms of intestinal obstruction with the diagnosis made by plain abdominal radiography. Medical treatment by enzymic or endoscopic fragmentation was used for 17 of 30 gastric bezoars; surgery was required in the remainder. Intestinal bezoars causing obstruction can be fragmented and 'milked' to the caecum. The stomach should be explored for associated gastric bezoars.

Duodenogastric reflux quantification in peptic ulcer surgery: comparison between different surgical techniques.

BACKGROUND: We quantified duodenogastric reflux with 6-hour continuous intravenous infusion of technetium 99m-labeled hepatoiminodiacetic acid (99mTc-HIDA) and subsequent quantification in gastric juice. METHODS: For this purpose, 50 patients were studied who had undergone surgery on the stomach with different surgical techniques: bilateral vagotomy plus Heineke-Mikulicz pyloroplasty, bilateral truncal vagotomy plus anterior pylorectomy, proximal gastric vagotomy, antrectomy and Billroth I reconstruction, and antrectomy and Billroth II reconstruction, comparing them with 10 healthy subjects used as a control group. We also studied the existing correlation between the rates of reflux determined by 99mTc-HIDA and those of total bile acids in gastric juice. RESULTS AND CONCLUSIONS: Patients who underwent gastric surgery had significantly greater quantities of duodenogastric reflux (p < 0.001) than had the control group. When the groups undergoing gastric surgery were compared, the patients who underwent resection showed higher reflux rates (p < 0.001) than did the patients who did not undergo resection. We found no differences among the groups of patients who did or did not undergo resection. We also found a highly significant correlation (p < 0.001) between the concentrations of 99mTc-HIDA and bile acids in gastric juice.
