Feasibility and cost effectiveness of ambulatory laparoscopic cholecystectomy. A retrospective cohort study.

Ambulatory surgery is an efficient, safe and widely performed procedure; this study would shows the advantages of the ambulatory laparoscopic cholecystectomy procedure from the point of view of patients and the Hospital/National Health System. Materials and Methods: Single-center retrospective cohort study including 288 patients who underwent laparoscopic-cholecystectomy at **** from January 2016 to July 2018. Ambulatory LC were compared to well-matched inpatient procedures performed in the same study period. The primary endpoints was the 30-day readmission rate. Secondary endpoints were the discharge rate in the ambulatory group, the post-operative complications rate and cost effectiveness. Results: 120/288 (41.7%) patients underwent ambulatory laparoscopic cholecystectomy. Thirty-two (26.7%) patients who underwent ambulatory laparoscopic cholecystectomy had major preoperative comorbidities and 35 (29.2%) had undergone prior abdominal surgery. The readmission rates for ambulatory patients and inpatients were 0.8% and 1.7% (p = 0.56), respectively; 104 (86.7%) ambulatory patients were discharged successfully on the same day. The two groups showed the same post-operative complication rate (p = 0.40). Ambulatory procedures resulted in related cost savings of more than 300% for the hospital and a remarkable financial benefit for the National Italian Healthcare System, accounting for savings exceeding € 27 000 per year. Conclusions: Ambulatory laparoscopic cholecystectomy is safe and cost effective. Since a third of ambulatory patients showed comorbidity or previous abdominal surgery, we believe that this procedure may be performed safely in a tertiary HPB centre, even in complex patients.

Perianal Paget's disease: a case report and literature review.

Perianal Paget's disease is a rare condition characterized by an intraepidermal growth of neoplastic cells with apocrine glandular differentiation (Paget's cells), often associated with an underlying malignancy. Fewer than 200 cases have been reported in the literature over the past 20 years. Here we discuss the clinical case of a young woman who was referred to our institution for this rare disorder and briefly review the literature.

Ferguson hemorrhoidectomy with radiofrequency versus classic diathermy.

BACKGROUND: This randomized study compared results obtained with the Ferguson's technique for the treatment of hemorrhoids performed with a radiofrequency (RF) scalpel and traditional diathermy. METHODS: 28 patients affected by grade IV hemorrhoids were randomized to receive either the Ferguson operation with the RF scalpel (group A) or traditional diathermy (group B). The operating time, intra- and postoperative bleeding, postoperative pain, and overall patient satisfaction were all recorded. RESULTS: Six patients (three for each group) did not attend follow-up controls. Group A showed a significant reduction of the surgical time (23 vs. 33 min; p < .01), pain at first postoperative day (Visual Analog Scale [VAS] score 3.4 vs. 4.8; p < .05), and at the first evacuation (3.4 vs. 5.0; p < .05). No significant differences were observed for the pain score at the seventh postoperative day, or overall satisfaction scores at the 7th postoperative day, and six months postoperatively (p = NS). No severe complications were recorded. Two patients in group A (18.2%) and four patients in group B (36.4%) reported transitory gas incontinence that spontaneously resolved within one month (p = NS). Three patients in group A (27.3%) and four patients in group B (36.4%) required postoperative catheterization due to urinary retention (p = NS). CONCLUSIONS: RF scalpel shortens the operating time of the Ferguson operation and is less painful in the early postoperative period.

Results, outcome predictors, and complications after stapled transanal rectal resection for obstructed defecation.

PURPOSE: Obstructed defecation may be treated by stapled transanal rectal resection, but different complications and recurrence rates have been reported. The present study was designed to evaluate stapled transanal rectal resection results, outcome predictive factors, and nature of complications. METHODS: Clinical and functional data of 123 patients were retrospectively analyzed. All patients had symptoms of obstructed defecation before surgery and had rectocele and/or intussusception. Of them, 85 were operated on by the authors and 38 were referred after stapled transanal rectal resection had been performed elsewhere. RESULTS: At a median follow-up of 17 (range, 3-44) months, 65 percent of the patients operated on by the authors had subjective improvement. Recurrent rectocele was present in 29 percent and recurrent intussusception was present in 28 percent of patients. At univariate analysis, results were worse in those with preoperative digitation (P<0.01), puborectalis dyssynergia (P<0.05), enterocele (P<0.05), larger size rectocele (P<0.05), lower bowel frequency (P<0.05), and sense of incomplete evacuation (P<0.05). Bleeding was the most common perioperative complication occurring in 12 percent of cases. Reoperations were needed in 16 patients (19 percent): 9 for recurrent disease. In the 38 patients referred after stapled transanal rectal resection, the most common problems were perineal pain (53 percent), constipation with recurrent rectocele and/or intussusception (50 percent), and incontinence (28 percent). Of these patients, 14 (37 percent) underwent reoperations: 7 for recurrence. Three patients presented with a rectovaginal fistula. One other patient died for necrotizing pelvic fasciitis. CONCLUSIONS: Stapled transanal rectal resection achieved acceptable results at the cost of a high reoperation rate. Patients with puborectalis dyssynergia and lower bowel frequency may do worse because surgery does not address the causes of their constipation. Patients with large rectoceles, enteroceles, digitation, and a sense of incomplete evacuation may have more advanced pelvic floor disease for which stapled transanal rectal resection, which simply removes redundant tissue, may not be adequate. This, together with the complications observed in patients referred after stapled transanal rectal resection, suggests that this procedure should be performed by colorectal surgeons and in carefully selected patients.

The Zuckerkandl tubercle.

Identification and preservation of the recurrent laryngeal nerve is a major concern during thyroidectomies. The Zuckerkandl tubercle is an anatomic landmark that can be used for this purpose. It is generally found in 63% to 80% of patients undergoing thyroidectomy and is located between the superior and inferior lobes and points toward the tracheoesophageal groove. It is classified into three grades according to size: I <.5 cm, II .5 to 1 cm, III >1 cm. A grade III tubercle, present in 45% of patients, is sometimes associated with significant pressure symptoms in otherwise small-sized goiters.

Apoptotic death in deep partial thickness burns vs. normal skin of burned patients.

BACKGROUND: Deep partial thickness burns have an ambiguous behavior evolving either into spontaneous healing or full thickness burns. The aim of this study was to investigate these lesions for the presence of apoptosis thereby giving a possible cellular explanation to their peculiar clinical progression. METHODS: We used colocalization of DNA fragments (terminal deoxynucleotidyl transferase mediated dUTP nick end labeling) and Fas ligand CD95 antibodies to calculate the apoptotic rate of deep partial thickness burns and normal skin in 21 patients after acute thermal injuries (significant difference considered: P < 0.05). RESULTS: Deep partial thickness burns were associated with a higher apoptotic rate than normal skin (48.15% +/- 17.22% versus 18.6% +/- 7.2%; P = 0.0002). There were no apparent significant correlations of apoptotic rate with age, days from injury, total burn surface area or deep burn area except for a slight correlation with sex (r = 0.484; P = 0.02). CONCLUSIONS: A higher apoptotic rate was present in dermal cells of deep partial thickness burns if compared to that of the unburned skin. These data would suggest that deep partial thickness progression derive from apoptosis. Specific studies are required to confirm this hypothesis and to investigate its clinical and therapeutic significance.

Apoptotic cells are present in ischemic zones of deep partial-thickness burns.

Deep partial-thickness burns exhibit ambiguous behavior, either spontaneously healing or evolving into full-thickness burns. The aim of this study was to investigate these lesions for the presence of apoptotic cells and to compare their rate with that of superficial and full-thickness burns. We used colocalization of DNA fragments (ie, terminal deoxynucleotidyl transferase Biotin-dUTP nick end labeling) and Fas ligand CD95 antibodies to calculate the apoptotic rate of superficial, deep partial-thickness and full-thickness burns in 45 patients after the thermal injury. Biopsies were collected mainly during the acute postburn phase (first week of hospitalization). Deep partial-thickness burns presented apoptotic cells, both in the dermis and in cutaneous adnexa, and showed a higher apoptotic rate than superficial and full-thickness burns (44.5% in deep partial thickness, interquartile range 6.3-90.5%; 5.6% in superficial partial thickness, interquartile range: 0-13%; 0% for full-thickness burn; P = .000243). A significant greater apoptotic rate was present in cells of deep partial-thickness burns when compared with superficial and full thickness. These data would suggest that deep burns sustain an ischemic damage that forces cells to undergo apoptosis and could represent the biologic basis for their clinical evolution into full-thickness burns. Further correlation studies are now required to confirm this hypothesis.
