Laparoscopic cholecystectomy: do risk factors for a prolonged length of stay exist?

Gallstones are one of the most common morbidities in the world. Laparoscopic cholecystectomy is the gold standard for gallbladder stones' removal. Few studies focus on the existence of predictive factors aimed at facilitating cholecystectomy in a day surgery setting. The aim of this retrospective study was to identify clinical factors that could guide day-surgery laparoscopic cholecystectomy safety. The study included 985 consecutive patients who underwent elective laparoscopic cholecystectomy for gallstone disease between May 2006 and February 2015. Patients were divided into two groups: group A with a length of stay ≤ 2 days (922 patients); group B with a length of stay > 2 days (63 patients). Univariate analysis showed that age, sex and the presence of obesity, cardiological, and nephrological comorbidities had a higher likelihood of a longer hospital stay. The logistic regression model showed that only age was a significant predictor of a longer stay. No complication has reached the statistical significance of extending the length of stay in group B. Conversely, the presence of such comorbidities has influenced the hospitalization. Our results allow the identification of a category of patients at high risk of hospitalization within 1 or 2 days from treatment. Moreover, we reported that there is no complication specifically affecting the length of stay. Our findings support the idea that a prolonged length of stay is not linked to the surgical procedure but to the patient's comorbidities.

A Randomized Trial Comparing Stapled Rectal Mucosectomy Versus Open and Semiclosed Hemorrhoidectomy.

BACKGROUND: Different results have been reported concerning the postoperative outcomes of different surgical approaches for hemorrhoids. OBJECTIVE: We aimed to determine the postoperative outcome following 3 main surgical techniques. DESIGN: A prospective, randomized trial was designed with 180 patients in 3 arms of 60 patients each. SETTINGS: The study was conducted from April 1999 to January 2007 at the University Hospital "Campus Bio-Medico di Roma." PATIENTS: All of the patients who were referred for hemorrhoid surgery were enrolled according to inclusion and exclusion criteria (ISRCTN12040297). INTERVENTIONS: Treatments according to the open, semiclosed, and stapled techniques were compared. MAIN OUTCOME MEASURES: Sample size was calculated to determine a difference in terms of the intensity of postoperative pain at the first week and the days required for return to work activity. RESULTS: After 1 week, patients who underwent semiclosed hemorrhoidectomy reported significantly less pain (p < 0.01) and a significant decrease in analgesic intake from the third postoperative day (p < 0.01) than after the other 2 techniques. The patients resumed work ≈11 days after semiclosed and stapled techniques (11.8 and 11.6 days), which was earlier compared with 21.3 days in the open group (p < 0.05). LIMITATIONS: The high number of patients excluded might be considered a limitation of the study, but our selection criteria including patients living within 50 km of the hospital allowed for a low rate (9.4%) of patients lost to follow-up. CONCLUSIONS: This study found an earlier resumption of work and less pain in patients who underwent the stapled and semiclosed procedures rather than open, which was associated with more complications, particularly because of a higher rate of stenosis (see Video, Supplemental Digital Content 1, http://links.lww.com/DCR/A196).

Infusion of bevacizumab increases the risk of intestinal perforation: results on a series of 143 patients consecutively treated.

Bevacizumab is largely used in colorectal cancer patients. Postsurgical healing complications have been described for patients following treatment with Bevacizumab. We report three cases of spontaneous intestinal perforation following infusion of Bevacizumab. From January 2002 through October 2010, Bevacizumab was delivered in 143 patients. Spontaneous intestinal perforation occurred in 3 cases (2.1 %). Bevacizumab may result in severe complications. Therefore, it is important to consider every patient treated with Bevacizumab at risk for life-threatening gastro-intestinal complications.

A singular observation of a giant benign Brenner tumor of the ovary.

INTRODUCTION: Brenner tumors are rare transitional cell tumors of the ovary. They are usually benign neoplasms, of solid or solid-cystic structure and small size. We describe the case of a benign, predominantly cystic Brenner tumor measuring 39 cm in diameter. CASE REPORT: A 62-year-old woman presented to the outpatient visit complaining about vague abdominal symptoms such as constipation and meteorism. Ultrasonography and CT scan showed the presence of a voluminous cystic mass, with fluid content, displacing other intra-abdominal organs. The patient underwent elective surgical excision, and there were no complications. Definitive pathological examination showed a metaplastic benign Brenner tumor. CONCLUSION: The largest benign Brenner tumors reported in literature have been up to 30 cm in size, and greater size has been thought to be a predictor of malignancy. We have seen, however, that it is possible for larger lesions of this type to have a completely benign behavior; consequently, a benign nature should not be excluded even in the event of a large ovarian lesion.

First experience for the laparoscopic treatment of parastomal hernia with the use of Parietex composite mesh.

Parastomal herniation is a postoperative complication after colostomy or ileostomy with an incidence rate of 0-48.1%. Its repair is indicated in approximately 10-15% of cases; however, this surgery has been associated with a significant degree of morbidity and recurrence. We describe, for the first time in literature, an experience using a new technique, and a new type of mesh. This new type of laparoscopic parastomal hernia repair appears to be easier and faster. The follow-up was about 240 days. Our preliminary experience in using this technique and mesh appears to be possibly leading to a reduction of recurrences and complications. Randomized multicenter studies are required to assess the true effectiveness of the technique.

Is sacral nerve stimulation an effective treatment for chronic idiopathic anal pain?

BACKGROUND: Chronic idiopathic anal pain is a common, benign symptom, the etiology of which remains unclear. Traditional treatments are often ineffective. This study investigated the efficacy of sacral nerve stimulation in treating chronic idiopathic anal pain. METHODS: Twelve patients (10 women and 2 men; mean age, 61.0 +/- 10.3 years; range, 48-82 years) implanted with a permanent device for sacral nerve stimulation were followed in the Italian Group for Sacral Neuromodulation (GINS) Registry. All patients had frequent chronic anal or perianal pain; 75 percent had previously undergone pelvic surgery. Pharmacologic and rehabilitative therapy had yielded poor results. Changes from baseline to last follow-up examination were evaluated for scores on a visual analog pain scale (0-10) and the Short-Form 36 (SF-36) health status questionnaire. Manometric measurements recorded at last follow-up were compared with preimplantation values. RESULTS: In one patient, the permanent device was removed because of technical failure. After a mean follow-up of 15 (range, 3-80) months, visual analog pain scores had significantly improved (from 8.2 +/- 1.7 to 2.2 +/- 1.3, P < 0.001). SF-36 physical component scores increased from 26.27 +/- 5.65 to 38.95 +/- 9.08, P < 0.02). Scores on the mental component showed improvement, although not significant. Postimplantation changes in manometric functional data were not significant, but sensitivity thresholds showed a considerable decrease. CONCLUSIONS: Long-term follow-up data showing improvements in scores on the visual analog pain scale and quality of life questionnaire indicate that, before adopting more aggressive surgical procedures, SNS should be considered for patients with chronic idiopathic anal pain in whom pharmacologic and biofeedback treatments have failed to produce effective results.

Is total colectomy the right choice in intractable slow-transit constipation?

BACKGROUND: The aim of the study was to evaluate the functional results of surgical treatment for intractable slow-transit constipation and to establish that the importance of correct diagnosis and type of colon resection (total or segmental) is essential to achieve optimal outcome while minimizing side effects. METHODS: Between 1995 and 2004, of the 450 patients presenting with chronic constipation, we further investigated 33 patients with a diagnosis of slow-transit constipation that had not improved with medical or rehabilitative treatment. Preoperative evaluation included a daily evacuation diary compiled using Wexner score, psychologic assessment, Medical Outcomes Study 36-item Short Form Health Survey (SF-36), radiologic investigation of colonic transit time, enema radiograph, colpo-cysto-defecography, anal manometry, and, in selected patients, colonoscopy and pudendal nerve terminal motor latency. In 15 cases, the cause of constipation was colonic slow-transit (with a mean Wexner score of 22), which was always associated with dolichocolon. The other 18 patients presented outlet obstruction, and, therefore, these results are not included in the present report. The 15 patients with slow-transit constipation were submitted to total laparoscopic colectomy (2), total open colectomy (6), and left laparoscopic hemicolectomy for left colonic slow-transit (7). RESULTS: Mean follow-up was 38 months. All patients except 1 presented improvement in symptoms with daily evacuations (P < .01; mean Wexner score, 6). Furthermore, results of the SF-36 test showed an improvement in the perception of physical pain, and the emotional, psychologic, and general health spheres after surgical treatment. CONCLUSIONS: Meticulous preoperative evaluation of intractable slow-transit constipation may discriminate between the different causes of chronic constipation and thus avoid the well-known "Iceberg syndrome," which is responsible for many treatment failures.

Persisting perianal ulcer after radiotherapy for anal cancer: recurrence of disease or late radiation-related complication?

We report the case of a 47-year-old HIV-negative male affected by a perianal ulcer which occurred after chemoradiation delivered for anal cancer. In spite of a negative biopsy the lesion was highly suspected to be a disease recurrence. Uncontrollable pain and anal stenosis were also present; abdominoperineal resection with a large excision of perianal tissues and reconstruction with bilateral musculocutaneous gracilis flaps was therefore performed. Histology did not confirm tumor recurrence. Thirteen months after surgery, the patient is still alive and free of disease. The introduction of radiotherapy and concomitant chemotherapy has revolutionized the treatment of anal cancer, avoiding demolitive surgery in a large subset of patients. Radionecrosis is an uncommon but potentially devastating event occurring in up to 10% of patients undergoing radiotherapy for anal cancer. It causes clinical (pain, anal stenosis, mucositis and diarrhea) and diagnostic problems (recurrence vs. benign post-attinic lesion). In the present article we review this uncommon complication, discuss the technical surgical aspects associated with a very large perianal tissue removal, and data of the most recent literature in this field.

Reliability of electrophysiologic anal tests in predicting the outcome of sacral nerve modulation for fecal incontinence.

INTRODUCTION: Sacral nerve modulation has been demonstrated to be a new efficacious treatment for fecal incontinence. The effectiveness of the procedure is preliminarily tested by means of a peripheral nerve evaluation. Integrity of the sacral neural pathway is generally believed to be a necessary condition for a good response, but no data are available to confirm whether electrophysiologic anal tests are predictive of the clinical outcome of the peripheral nerve evaluation. METHODS: Eighty-two incontinent patients underwent the peripheral nerve evaluation after full evaluation of the anorectal physiology. Univariate analysis was performed, and the positive predictive value, sensitivity, and specificity were calculated for each of the tests. RESULTS: Forty-six patients had successful results to the peripheral nerve evaluation and were subjected to permanent implant of a sacral electrostimulator. Anal sphincter electromyography had been performed in 60 patients, whereas pudendal nerve terminal motor latency had been assessed in 68 and evoked sacral potentials in 29 patients. Anal electromyography was statistically related to the outcome of the peripheral nerve evaluation ( P = 0.0004) with a positive predictive value of 81 percent, a sensitivity of 44 percent, and a specificity of 81 percent. Pudendal nerve terminal motor latency on the right side did not correlate with the outcome, but left pudendal nerve terminal motor latency was weakly correlated ( P = 0.02), although both tests had a low positive predicting value and sensitivity vs. good specificity. Evoked sacral potentials did not correlate with the outcome and had a low positive predictive value, sensitivity, and specificity. CONCLUSIONS: Simple anal sphincter electromyography can predict the outcome of the peripheral nerve evaluation with good positive predictive value and specificity in patients with fecal incontinence. Other, more expensive, electrophysiologic anal tests do not add further prognostic information.

Mucinous cystic lesions of the pancreas. Report of a patient submitted to distal pancreatectomy.

Intraductal papillary neoplasm consists a variant of the mucin-producing neoplasms of the pancreas; these are rare diseases that can be divided into mucinous ductal ectasias and intraductal papillary neoplasms. Such neoplasms have a malignant potential, and their prognosis is good if they are early diagnosed and localized surgical resection. This paper describes a case of an intraductal papillary neoplasm localized in the tail of the pancreas and treated by distal splenopancreatectomy. The literature on this rare disease is also reviewed.

Rectal perforation, retropneumoperitoneum, and pneumomediastinum after stapling procedure for prolapsed hemorrhoids: report of a case and subsequent considerations.

Stapling procedure is a new technique for the surgical management of third-degree hemorrhoids. Even if long-term experience has not been reported, this new technique is generating a lot of interest and its use is becoming more common in Europe. Some articles have just been published about severe adverse effects of this operation, and in the present article we describe a case of a life-threatening complication that occurred with the use of the stapling technique for hemorrhoidectomy. A patient with perineal descensus and third-degree hemorrhoids underwent a stapling procedure for the treatment of hemorrhoids. Retropneumoperitoneum and pneumomediastinum developed on postoperative Day 2 and a colostomy was performed, allowing a quick recovery of the patient. After six months the colostomy was closed and bowel function restored. Our experience, taken together with some other cases previously published of severe complications after such an operation, suggests caution in the use of this new technique for the treatment of a benign disease.
