Cathamenial pneumothorax.

Cathamenial pneumothorax is a relatively low-frequency pathology (approximately 100 cases cited in the literature) characterized by recurrent pneumothorax episodes during the menstruation period. We report on a 34-year-old female patient who had recurrent pneumothorax that did not respond to chest drainage and whose presentation was directly related to the menstruation period. Our patient also had a significant clinical record for pelvic endometriosis. She underwent video-assisted thoracoscopic exploration (VATS) of the pleural cavity and dystrophic parenchymal blebs of the middle lobe were found. An atypical resection of the bollous tissue was performed and pleurodesis completed the intervention. During VATS no ectopic endometriosis foci or diaphragmatic fenestrations (widely considered as a possible cause of this clinical picture) were evidenced.

Is the loss of gallstones during laparoscopic cholecystectomy an underestimated complication?

Laparoscopic cholecystectomy entails an increased risk of gallbladder rupture and consequent loss of stones in the abdominal cavity. Herein we report the case of a 51-year-old male patient, who underwent laparoscopic cholecystectomy 2 years before presentation to our hospital. He had experienced tension sensation and epigastric pain since 4 months postoperatively. A well-defined epigastric mass, which was hard and painful on palpation, was detected and later confirmed by ultrasonography and CT scan. Explorative laparotomy revealed a mass in the area of the gastrocolic ligament,resulting from biliary gallstones in conjunction with a perimetral inflammatory reaction. A review of the literature showed that the incidence of gallbladder lesions during laparoscopy is 13-40%. In order to prevent this complication, meticulous isolation of the gallbladder, proper dissection of the cystic duct and artery, and careful extraction through the umbilical access are required. Ligation after the rupture or use of an endo-bag may be helpful. The loss of gallstones and their retention in the abdominal cavity should be noted in the description of the surgical procedure.

Carcinoma of the head of the pancreas: review of 67 cases and comparison with 27 additional periampullary carcinomas.

BACKGROUND/AIMS: Carcinoma of the head of the pancreas is reported with increasing incidence. The classical Whipple procedure, modified by Traverso and Longmire, is a major surgical undertaking and there is question on its indication in the case of lesions which, although technically resectable, are not susceptible to cure. PATIENTS AND METHODS: We review 67 cases of carcinoma of the head of the pancreas comparing the results of radical vs. palliative surgery. The results were then compared with 27 additional cases of periampullary carcinomas. RESULTS: Long term survival was obviously higher after resection, due to the more advanced tumor stage in the palliation group. However, perioperative mortality, supposedly high in extensive resective surgery, was 8.7% (vs 11.9% in the palliation group). CONCLUSIONS: At present, extensive resective surgery carries unacceptable incidence of perioperative mortality. Therefore we suggest that indication for resection should be widened, as it may offer better chances of cure in resectable periampullary carcinomas and, even in non curable cases, it offers better quality of life and the advantages of tumor debulking.

[Surgical treatment of ulcerative rectocolitis: technical aspects of total restorative proctocolitis with S pouch]. / Il trattamento chirurgico della rettocolite ulcerosa: aspetti tecnici della proctocolectomia totale restaurativa con pouch a S.

Restorative proctocolectomy with an ileal-pouch-anal anastomosis seems to be the treatment of choice for ulcerative colitis. The aim of this study was to discuss a number of technical and functional aspects of the procedure that still appear to be controversial such as the shape of the pouch, the mucosectomy and the type of anastomosis. The authors report on their experience with the surgical treatment of ulcerative colitis with an "S" pouch. The technique reported, however, differs from the original method proposed by Parks and Nicholls in 1978 and the reasons for this surgical choice are discussed. A six-year experience (1993-1999) regarding 35 patients undergoing this approach is reported. No perioperative deaths were observed. The early and long-term complication rates were 8.5% and 11.4%, respectively. The average number of daily evacuations was 4. Mucosectomy affords complete resolution of the disease, while the particular shape of the pouch guarantees good functional results.

[The conservative surgery of Crohn's disease: the long-term results]. / La chirurgia conservativa della malattia di Crohn: risultati a lungo termine.

INTRODUCTION: Patients with Crohn's disease (CD) receive one or more surgical interventions throughout their clinical history. Conservative surgery has recently been proposed as a safe and effective option for the treatment of complicated CD and for the prevention of short bowel syndrome and stoma. PATIENTS AND METHODS: One hundred nineteen patients affected by CD were treated with stricture plasty and mini-resection in our Department between January 1993 and January 1998. At admission, the prior complete clinical and surgical history of each patient was collected and then inserted in a prospectively maintained data base. Analysis of recurrence was made using the Kaplan-Meier function and the influence of certain variables on the risk of recurrence was analyzed using a Cox proportional hazard model. RESULTS: Perioperative mortality was nil, postoperative complications occurred in 8 patients (6.7%). Overall long term surgical recurrence at 5 years was 28%, 35% in patients operated on within one year and 15% in those treated after one year from the diagnosis (p < .05). CONCLUSIONS: Stricture plasty and minimal resections show lower perioperative mortality and postoperative complications similar to resective surgery. From risk factor analysis, a group of patients with high risk of surgical recurrence emerged. In this group and whenever technically possible, we consider stricture plasty and minimal resection the gold standard in the treatment of complicated CD.

Lymphocytic subpopulation changes after open and laparoscopic cholecystectomy: a prospective and comparative study on 38 patients.

Up to now it has been unclear whether laparoscopic surgery has fewer immunosuppressive effects than traditional laparotomic procedures. In a series of 38 patients affected by symptomatic gallstone disease and operated on either by laparoscopy (group 1) or by traditional open surgery (group 2), we determined the postoperative changes in lymphocyte subpopulations up to postoperative day (POD) 30. We collected 15 ml of venous blood from all patients in both groups on the day before surgery and on POD 1, 7, 15, and 30. A control group (group 3) comprised 56 healthy volunteers; the control group was used only to ensure that baseline values were totally comparable with a normal population; only one blood sample was obtained from the subjects in group 3. Patients undergoing open cholecystectomy had a significant decrease in total lymphocyte count on POD 1. Basal levels of lymphocyte subpopulations did not differ significantly in the study and control groups. No differences were found in the preoperative lymphocyte cell counts in the two groups who underwent cholecystectomy. Pan-T cells (CD3) showed a statistically significant marked reduction throughout the observation period. The counts of helper (CD4), suppressor (CD8), and natural killer NK (CD16) T cells were reduced on POD 1; the NK cell (CD16) count remained low until POD 30, B lymphocytes showed no postoperative reduction. In patients who underwent laparoscopic cholecystectomy, a significant postoperative decrease in total lymphocyte count, and in CD3, CD4, and CD8 subpopulations was observed on day 1 only. There was no reduction in CD16 and CD19 subpopulations. A comparative statistical analysis of lymphocyte subpopulations in the two groups was carried out: In the open cholecystectomy group, compared with the laparoscopy group, CD3, CD4, CD8, and CD16 lymphocyte subpopulations showed marked reductions at different time points. In particular, statistically significant differences were found in CD3 levels from POD 1 through POD 30, in CD4 from day 1 through day 7, and in CD8 and CD16 only on day 1.
