Predictive factors for functional failure of ventral mesh rectopexy in the treatment of rectal prolapse and obstructed defecation.

BACKGROUND: Ventral mesh rectopexy (VMR) is widely accepted for the treatment of rectal prolapse or obstructed defecation. However, despite good anatomical results, the improvement of functional symptoms (constipation or incontinence) cannot always be obtained and in some cases these symptoms may even worsen. The aim of the present study was to identify possible predictors of functional failure after VMR. METHODS: Data of all consecutive patients who had VMR for the treatment of rectal prolapse and/or obstructed defecation between January 2017 and December 2020 in three different pelvic floor surgical centres in Italy were analysed to identify possible predictors of functional failure, intended as persistence, worsening or new onset of constipation or faecal incontinence. Symptom severity was assessed pre- and postoperatively with the Wexner Constipation score and Obstructed Defecation Syndrome score. Quality of life was assessed, also before and after treatment, with the Patients Assessment of Constipation Quality of Life questionnaire, the Pelvic Floor Disability Index and the Pelvic Floor Impact Questionnaire. Faecal incontinence was evaluated with the Cleveland Clinic Incontinence Score. The functional outcomes before and after surgery were compared. RESULTS: Sixty-one patients were included (M:F ratio 3:60, median age 64 years [range 33-88 years]). Forty-two patients (68.9%) had obstructed defecation syndrome, 12(19.7%) had faecal incontinence and 7 patients (11.5%) had both. A statistically significant reduction between pre- and postoperative Obstructed Defecation Syndrome and Wexner scores was reported (p < 0.0001 in both cases). However, the postoperative presence of constipation occurred in 22 patients (36.1%) (this included 3 cases of new-onset constipation). The presence of redundant colon and the pre-existent constipation were associated with an increased risk of persistence of constipation postoperatively or new-onset constipation (p = 0.004 and p < 0.0001, respectively). The use of postoperative pelvic floor rehabilitation (p = 0.034) may reduce the risk of postoperative constipation. CONCLUSIONS: VMR is a safe and effective intervention for correcting the anatomical defect of rectal prolapse. The degree of prolapse, the presence of dolichocolon and pre-existing constipation are risk factors for the persistence or new onset of postoperative constipation. Postoperative rehabilitation treatment may reduce this risk.

Laparoscopic Appendectomy Performed by junior SUrgeonS: impact of 3D visualization on surgical outcome. Randomized multicentre clinical trial. (LAPSUS TRIAL).

BACKGROUND: The purpose of this study was to evaluate the effect of 3D visualization applied to laparoscopic appendectomy (LA) performed by young surgeons (YS). We considered both operative features and clinical outcomes, aiming to highlight the benefits that this technology could bring to novice surgeons and their laparoscopic training. METHODS: All the surgical procedures were performed by residents who had performed less than 20 appendectomies prior to the beginning of the study under the supervision of an expert surgeon. At the time of enrolment patients were randomized into two arms: Experimental arm (EA): laparoscopic appendectomy performed with laparoscopic 3D vision technology. Control arm (CA): laparoscopic appendectomy performed with the "standard" 2D technology. The primary endpoint was to find any statistically significant difference in operative time between the two arms. Differences in conversion rate, intra-operative complications, post-operative complications and surgeons' operative comfort were considered as secondary endpoints. RESULTS: We randomized 135 patients into the two study arms. The two groups were homogeneous for demographic characteristics, BMI and ASA scores. The characteristics of clinical presentation and anatomical position showed no significant difference. The operative time was longer in the CA (57.5 vs. 49.6 min, p = 0.048, 95% CI). In the subgroup of complicated appendicitis, this trend toward inferior operative time was confirmed without reaching statistical significance (2D = 60 min, 3D = 49.5 min, p = 0.082 95% CI). No intra-operative complications were observed in either group. The conversion rate was 5.6% (4 patients) in the 2D group and 4.6% (3 patients) in 3D group. CONCLUSION: The utilization of 3D laparoscopy was associated with reduction in operative time without influencing other parameters, in particular without altering the safety profile of the procedure.

The role of tibial nerve stimulation for enhanced postoperative recovery after colorectal surgery: a double-blind, parallel-group, randomized controlled trial.

BACKGROUND: Postoperative ileus (POI) is the most common cause of prolonged hospital stay following abdominal surgery, despite an optimized enhanced recovery after surgery (ERAS) program. The aim of the study was to evaluate the role of postoperative transcutaneous electrical tibial nerve stimulation (TTNS) in the recovery of bowel function and in shortening hospital stay after colonic resection. METHODS: Patients having elective laparoscopic colonic surgery within an ERAS program at our institution between June 2016 and June 2019 were enrolled and randomly assigned to a treatment protocol with TTNS or sham electrical stimulation. The primary endpoint was the time of recovery of gastrointestinal motility, measured as the first passage of stool. Secondary endpoints included: first passage of flatus, length of hospital stay, and complication rate related to the use of TTNS. RESULTS: One hundred and seventy patients who had right hemicolectomy (median age 71 years (range 43-89 years); 47.5% women) and 170 patients who had left colectomy (median age 67 years range (37-92 years); 41.5% women) were enrolled. The only factor significantly affected by TTNS was time to first passage of flatus after right hemicolectomy (reduced from 46 to 33 h, p = 0.04). However, if only patients with low compliance to early oral nutrition (63 of 340; 18.5%) were considered, a statistically significant difference in time until first flatus (p < 0.01) and first bowel movement (p < 0.0001) and a shorter time until discharge (median 5 vs 7 days) were found in both left and right colectomies groups, respectively. CONCLUSIONS: TTNS may have a positive effect on gastrointestinal tract motility and recovery from POI after colorectal surgery in a selected group, who has low compliance with an ERAS program, without increasing the risk of complications.

Diagnostic and therapeutic role of laparoscopy in perforated peptic ulcer in the elderly patients.

AIM: The purpose of this study is to analyze the outcome of elderly patients with perforated peptic ulcer comparing laparoscopic treatment versus open approach. METHODS: In our General and Emergency Surgery Unit in the last 3 years, 20 elderly patients with perforated peptic ulcer were performed. We considered elderly all patients over the age of 65 years (10 females and 10 males; the mean age was 75 years). 16 patients (80%) were submitted to laparoscopic repair with omentoplasty and 4 (20%) to open repair. The patients were classified using the Boye's score which influenced the choice of surgical treatment and the outcoEmergency Romame. The two groups were compared in terms of operative surgery times, complication rate, mortality and postoperative outcomes. DISCUSSION: Perforated peptic ulcer is a common abdominal disease that is treated by surgery. The potential advantages of laparoscopy, both in terms of diagnosis and therapy, are clear and the major advantages may be observed in cases with peritonitis secondary as a perforated peptic ulcer where laparoscopy allows the confirmation of the diagnosis, the identification of the position of the ulcer and the repair. With the age the risks of comorbidities increases multidisease syndrome. Elderly patients suffer from frailty syndrome. All these factors make the elderly patient a major challenge for a laparoscopy treatment. CONCLUSION: The laparoscopic approach is an effective method for treatment of perforated peptic ulcer in the elderly with a great diagnostic and therapeutic role. Nowadays more prospective randomized studies are needed to evaluate the effectiveness of laparoscopic versus open repair.

Life-threatening bleeding for a large cameron ulcer. A novel description of a tailored-surgical strategy: report of a case and literature overview.

Hiatal hernias (HHs) are usually divided into two main groups: sliding and para-esophageal (torsional) ones. Sometimes patients presenting HHs experience progressive anemia, whereas rarely an acute anemia with melena or hematemesis can occur. In such cases a Cameron ulcer should be suspected and a careful esophago-gastro-duodenoscopy (EGDS) with a meticulous inspection of the mucosal folds along the neck of the hernia is the best examination in order to find out the ulcer itself. In front of massive hemorrhage due to a Cameron erosion, the first aim should be the control of the bleeding itself, in order to ree1Romastablish hemodynamic stability. The Authors report the case of a 72-year-old man presenting a severe bleeding secondary to a large Cameron ulcer in a para-esophageal hiatal hernia. Firstly, a combined medical-endoscopic therapy was tried; the patient underwent transfusions of pooled red blood cells and endovenous anti-acid therapy combined with an operative endoscopic treatment; unfortunately this initial approach failed, therefore the patient was referred to surgery. The surgeons realized a minimally invasive atypical gastric resection associated with the HH repair; the post-operative course was uneventful and no other rebleeding episodes occurred. The urgency treatment of a life-threatening bleeding for Cameron ulcers remains a very challenging problem as no univocal and standardized recommendation has been described in literature since now. In this case-report the Authors make an overview of the current literature on the treatment of Cameron ulcers, describing a novel surgical technique for massive upper gastro-intestinal bleeding secondary to these lesions.

A dramatic and rare complication: bowel perforation following abdominal liposuction.

AIM: The purpose of this study is to analyze a rare and under-reported complication of abdominal liposuction and the role of laparoscopy. CLINICAL CASE: We report a case of bowel perforation after 7 days of abdominal liposuction and bilateral mastopexy. The patient presented clinical and radiological findings of bowel obstructive syndrome and bilateral peripheral pulmonary embolism. An emergency diagnostic laparoscopy was performed and confirmed the diagnosis of bowel perforation. DISCUSSION: Bowel perforation is a known but under-reported comSOD Romaplication of abdominal liposuction, and it is characterized by a difficult diagnosis. The clinical presentation is characterized by a difficult diagnosis and severe complications. Bowel obstructive syndrome was constant, as our case and also peritonitis was never frank. This is an important point because it is one of the reasons for diagnostic delay. The development of laparoscopic surgery has changed the way to manage such conditions, where the diagnosis was doubt. In particular, when an acute abdomen occurs, laparoscopy may have three different roles: to confirm or not the diagnosis, to facilitate and guide a subsequent laparotomy or, finally, to entirely treat the disease. CONCLUSION: The bowel perforation is a dramatic and underestimated complication of abdominal liposuction. Diagnosis is complex. A clinical and radiological investigation should be quickly performed. In doubtful cases, an emergency laparoscopy can confirm the diagnosis and guide a possible subsequent laparotomy.

[Update on the laparoscopic adrenal surgery in the second decade of the century: "doubts no more?]. / Update sulla chirurgia laparoscopica del surrene nel secondo decennio del secolo: "doubts no more?"

Laparoscopic adrenal surgery has significantly improved during the last years. Thus at the moment it is possible to define such technique as the therapeutic "Gold Standard" option in the treatment of the adrenal tumors. However, some doubts are still remaining concerning the feasibility of laparoscopic adrenalectomy in case of malignant adrenal tumors, hyper-vascular tumors (pheochromocytoma) and indeterminate incidentaloma. This study aimed to review all the literature of the last three years (only article with abstracts) using the criteria of selection of the Cochrane Library, in order to find class I and class II-III studies which are able to surely or, respectively, probably respond to the various questions yet to be answered Two hundred and twelve papers have been selected. The class I studies stated the following evidences: laparoscopic treatment of pheochromocytoma is the Gold Standard too, independently from the dimension; the short term results of laparoscopic anterior and posterior approach are equivalent to those of the lateral one. Doubts still remain concerning the role of laparoscopy in the treatment of metastases, big pheochromocytomas, small size incidentalomas (risk of over-treatement). Nearly no respond has been given to others issues such as "the single port techniques" in laparoscopic adrenalectomy, the role of radiofrequency laparoscopic ablation of the adrenal tumor, the kind of treatment of stadium I and II adrenocortical carcinoma and big size (> 8 cm) tumors, the management of non-functioning incidentaloma of 4-6 cm, the role of the robot, and, finally, the approach of the bilateral tumors. We conclude that, despite many issues on the feasibility and safety of laparoscopy in the adrenal surgery have been definitely clarified, so that such technique has been declared the "Gold Standard" method in the treatment of the adrenal tumor, doubts still remain in some aspects of this method. However, since the researches in this field are proceeding with high evolution velocity, in the next future most of the questions that are still present should be definitively adressed.

[Ileal duplication in adults. A very rare nosological entity]. / La duplicazione ileale dell'adulto. Una rarissima entità nosologica.

The report presents a rare case of intestinal duplication in a 43-year old female. Intestinal duplication is a rare congenital malformation and is extremely exceptional in adults. A lot of etiopathogenic theories have been advanced to explain this malformation that can occur anywhere along the alimentary tract, even if the ileum remains the most common. It may be cystic or tubular. An important aspect of mucosal histology is the possibility of gastric heterotopy, conditioning a particular treatment. The literature shows 14 cases with clinical very different presentations and instrumental exams were rarely helpful for correct diagnosis. Treatment of choice is surgical complete resection of the duplication. When contiguous structures are involved intestinal bypass or Roux-on-Y anastomosis may be necessary with mandatory stripping of the mucosa when heterotopic gastric mucosa is present in order to prevent the risk of gastrointestinal haemorrhage or malignant transformation, an event possible in about 25% of the cases reported in the literature.

[The solitary rectal ulcer today. A review of the literature]. / L'ulcera solitaria del retto oggi. Revisione della letteratura.

The solitary rectal ulcer (SRU) is a benign lesion of adults of either sex, which presents with chronic constipation, peculiar defecatory disorders, rectal prolapse and smaller psychological abnormalities. The characteristic appearance of this disease is a "neither being always ulcerate, nor always solitary" lesion, but often with polypoid or granular feature, typically localized in anterior rectal wall, a few inches from anal channel. Distinctive histopathological specimens are localized mucosal distortion, hypertrophic proliferation of muscularis mucosae and obliteration of lamina propria by fibroblasts and muscle fibres from the muscularis mucosae. Very few intermittent or recurrent symptoms are rectal bleeding and mucous discharge with defecations, difficulty of a complete ampullar evacuation and sometimes pelvic or rectoperineal pain. Clinical picture and endoscopic biopsies led to diagnosis. Barium enema, defecography, transrectal ultrasound, manometry and electromyography have an additional role. Medical treatment is performed by high-fiber diet, but biofeedback training is very helpful. Surgical management is as an excisional surgery, as a rectopexy if there is prolapse. Fecal diversion and rectocolic resection are considered only for patients with obstinate and severe symptoms. Even in patients who seem to advocate a surgical approach it is important to heal a dyskinetic puborectalis muscle.

Gamma nailing for the treatment of subtrochanteric nonunion: two clinical cases.

The authors propose two cases of subtrochanteric nonunion (one infected) treated by Gamma nailing. Early movement and the fact that weight-bearing is allowed are particularly advantageous for functional recovery. This method is proposed as a good alternative to open osteosynthesis with bone grafting.

Surgical treatment for infections of the cervical spine.

Non-specific and tuberculous infections of the cervical spine are a rare disease in developed countries. In 1962-1988 in the Orhopaedic Institute Rizzoli 32 patients with spondylitis of the cervical spine were treated. Twenty-nine patients came from Italy and three from Africa. Tuberculous infection was present in 23 patients, non-specific infection in nine. Eight tuberculous infections were in the atlanto-axial junction, the remaining ones at lower levels. The diagnosis was assessed by clinical and X-ray methods, only in four instances it was verified by histological examination. Conservative treatment was provided in 26 patients and surgery in five. In the nine non-specific infections orthopaedic and antibiotic treatment was successful, three patients were operated, their case-histories are presented. All cases of tuberculous inflammations were treated conservatively by immobilization and antituberculous treatment. Only in two surgery was called for due to instability of the spine. Both case-histories are presented. Based on the assembled results, the authors recommend in the discussion indications for and the procedure of conservative treatment and in exceptional cases surgical treatment of infections affecting the cervical spine. Key words: infection of the cervical spine, conservative and surgical treatment.

Lateral discoid meniscus: treatment and results.

Forty-six patients (47 knees) who had symptomatic discoid lateral menisci were operated on between August 1981 and May 1989. The patients were categorized according to Watanabe's classifications: complete (80.8%), incomplete (10.6%), and Wrisberg type (8.5%). The treatment of the discoid meniscus is based on total or partial meniscectomy, achieved by the percutaneous or arthrometric technique. Of the 47 knees, 30 underwent a follow-up evaluation. Using Ikeuchi's knee scale, 27 cases (90%) had either excellent or good ratings, and 3 (10%) received fair ratings. There were no poor outcomes. The results in the knees treated by partial meniscectomy were better than those in the knees treated with total meniscectomy.

[Fracture of the tibial plateau: results of surgical treatment]. / Le fratture del piatto tibiale: risultati del trattamento chirurgico.

The different types of tibial plateau fractures have similar problems. Today most of them are treated surgically to obtain the adequate reduction. Ninety-three fractures of the tibial plateau have been reviewed. The clinical and X-ray examinations were performed from 7 to 13 years after surgery. Poor results with ligamentous instability and posttraumatic arthritis seem to be related to insufficient reduction of the fracture, loose fragments in the joint, axial angulation and insufficient repair of ligaments and menisci.

Osteoid osteoma of the spine.

After reviewing the international literature the authors present three new cases of osteoid osteoma with vertebral body localisation, two in the lumbar region, and one in the cervical region. This rare localisation necessitates the use of accurate instrumental techniques, based on radiography, scintigraphy, and in particular, CT scanning, in order to arrive at a correct diagnosis as a prelude to the correct surgical treatment.
