Colocutaneous fistula through ulcerative colitis and cancer to the pyoderma gangrenosum: a never-ending story for a single patient. Case report.

BACKGROUND: Inflammatory bowel diseases may be associated with many extraintestinal complications, that in some cases can represent the first onset of these disorders. In particular during the course of the disease, Ulcerative Colitis develops extraintestinal manifestations very frequently. One of the rarest is pyoderma gangrenosum, a noninfectious neuthrophilic dermatosis, that can involve most commonly legs but also other parts of the skin or mucosas. It can be idiopathic or associated with gammopathies, vasculitis, chronic arthritis or, like in our case, with inflammatory bowel disease and malignancies. CASE PRESENTATION: A 38-year-old man was referred to our Department with a colo-cutaneous fistula in the left quadrant of abdominal wall. In the anamnesis he reported a trauma during a soccer match three weeks before. Through a CT scan and endoscopy with biopsy an inflammatory bowel disease with a segmental colitis and stenosis was diagnosed. After medical therapy, an initial radiological drainage and a period of parenteral nutrition, he underwent a left hemicolectomy. Despite the previous endoscopic biopsy the histopathological examination put in evidence not only inflammatory disease (in particular Ulcerative Colitis) but also a colorectal tumor pT4pN0. After the full recovery before chemotherapy he has developed on the chest and on the abdomen some painful nodules, with central necrosis, one of those in contact with one of the ribs. Through TC and RM it was impossible to understand the precise nature of these skin lesions. With biopsy a pyoderma gangrenosum was diagnosed and treated until complete resolution. DISCUSSION AND CONCLUSION: Management of inflammatory bowel diseases can be a true challenge, not only for the intestinal manifestations, but also for all the other features not related to gut. In some cases the same patient can develop many complications, such as malignancies or rare cutaneous diseases. Despite the initial surprise for such a weird evolution in a same patient, from fistula to inflammatory disease to cancer and finally to pyoderma gangrenosum, to face every single complication following consolidated diagnostic and pathological paths has been the correct strategy for controlling the disease.

Comparison of outcomes following intersphincteric resection vs low anterior resection for low rectal cancer: a systematic review.

BACKGROUND: Low Rectal Anterior Resection (LAR) is challenging when anal canal mucosa and/or internal sphincter are involved by very low tumors. In these cases, Intersphincteric resection (ISR) with the removal of the internal sphincter is designed to increase the distal margin of resection, thus preserving the external sphincter and pubo-rectalis muscle complex. Aim is to compare results after ISR with those of LAR, including subgroup analysis of open, laparoscopic and robotic ISR. METHODS: Studies published from January 1991 to January 2017 describing ISR and comparing results with LAR in adults were included irrespective of the technique. Tumor and surgical characteristics, clinical, functional and oncological results were collected. RESULTS: 25 non-randomized studies were included. Postoperative mortality ranged between 0% and 2.3%. The hospital stay ranged from 5 days to 40 days, lower in robotic ISR group if compared with laparoscopic ISR. Patients avoiding permanent stoma with ISR accept a lower continence level as satisfactory. Furthermore, anorectal function after ISR often tends to improve. ISR and LAR presented not statistically significant differences. Oncological outcomes were not statistically different Morbidity, blood loss and need for blood transfusions were lower in the laparoscopic ISR if compared with open approach. CONCLUSIONS: Morbidity could more frequently affect open ISR if compared with laparoscopic ISR. Functional outcomes were influenced by neoadjuvant CRT, but not by the surgical approach of reconstruction, while were positively influenced by partial ISR with respect to total ISR.

Modified transverse coloplasty pouch: new reconstruction techniques after total mesorectal excision. Our experience.

AIM: The incidence of rectal cancer continues to rise. The functional results after complete Total Mesorectal Excision (TME) depend on the segment of colon used for reconstruction of colonic continuity and the form, the volume and the functional proprieties of the "neorectum". The aim of our study is evaluate the efficacy of our Modified Transverse Coloplasty Pouch (MTCP) after the treatment of low rectal cancer in terms of functional outcomes and quality of life. PATIENTS AND METHODS: The study included 136 patients, underwent TME from January 2007 to December 2016 with diagnosis of extraperitoneal carcinoma of the rectum. The average distance of the tumor from the dentate line was 5.6 cm. Our follow-up protocol included functional outcome evaluation at 7th post-operative day (POD), 2nd month, and 6th month after the surgery. RESULTS: All patients (M/F 84/52) underwent anterior rectal resection (TME) with MTCP. Frequency of bowel movements per 24 hours in the studied patients compared at 7th POD, 2 months, and 6 months. Since the first post-operative weeks there is an encouraging reduction of the frequency of bowel movements. CONCLUSION: Modified Transverse Coloplasty Pouch (MTCP) had better functional results and quality of life compared to patients with a Colonic J Pouch (CJP) and traditional Transverse Coloplasty Pouch (TCP).

Reconnection surgery in adult post-operative short bowel syndrome < 100 cm: is colonic continuity sufficient to achieve enteral autonomy without autologous gastrointestinal reconstruction? Report from a single center and systematic review of literature.

A systematic bibliographic research concerning patients operated on for SBS was performed: inclusion criteria were adult age, reconnection surgery and SBS < 100 cm. Autologous gastrointestinal reconstruction represented an exclusion criteria. The outcomes of interest were the rate of total parenteral nutrition (TPN) independence and the length of follow-up (minimum 1 year) after surgery. We reviewed our experience from 2003 to 2013 with minimum 1-year follow-up, dealing with reconnection surgery in 13 adults affected by < 100 cm SBS after massive small bowel resection: autologous gastrointestinal reconstruction was not feasible. Three (out of 5168 screened papers) non randomized controlled trials with 116 adult patients were analysed showing weaning from TPN (40%, 50% and 90% respectively) after reconnection surgery without autologous gastrointestinal reconstruction. Among our 13 adults, mean age was 54.1 years (53.8 % ASA III): 69.2 % had a high stomal output (> 500 cc/day) and TPN dependence was 100%. We performed a jejuno-colonic anastomosis (SBS type II) in 53.8%, in 46.1% of cases without ileo-cecal valve, leaving a mean residual small bowel length of 75.7 cm. In-hospital mortality was 0%. After a minimum period of 1 year of intestinal rehabilitation, all our patients (100%) went back to oral intake and 69.2% were off TPN (9 patients). No one was listed for transplantation. A residual small bowel length of minimum 75 cm, even if reconnected to part of the colon, seems able to produce a TPN independence without autologous gastrointestinal reconstruction after a minimum period of 1 year of intestinal rehabilitation.

Surgery for post-operative entero-cutaneous fistulas: is bowel resection plus primary anastomosis without stoma a safe option to avoid early recurrence? Report on 20 cases by a single center and systematic review of the literature.

BACKGROUND: A review was performed on entero-cutaneous fistula (ECF) repair and early recurrence, adding our twenty adult patients (65% had multiple fistulas). METHODS: The search yielded 4.098 articles but only 15 were relevant: 1.217 patients underwent surgery. The interval time between fistula's diagnosis and operative repair was between 3 months and 1 year. A bowel resection with primary anastomosis was performed in 1.048 patients, 192 (18.3%) underwent a covering stoma: 856 patients (81.7%) had a fistula takedown in one procedure. RESULTS: The patients had 14.3% recurrence and 13.1% mortality rate. In our experience 75% were surgically treated after a period equal or above one year from fistula occurrence: surgery was very demolitive (in 40% remnant small bowel was less than 100 cm). We performed a bowel resection with a hand-sewn anastomosis (95%) without temporary stoma. In-hospital mortality was 0% and at discharge all were back to oral intake with 0% early re-fistulisation. CONCLUSIONS: Literature supports our experience: ECF takedown could be safely performed after an adequate period of recovery from 3 months to one year from fistula occurrence. In our series primary repair (bowel resection plus reconnection surgery without temporary stoma) avoided an early recurrence without mortality.

Pilonidal disease mimicking anterior anal fistula and associated with posterior anal fistula: a two-step surgery. Case report.

AIM: Anal fistula is a common disease originated from abscess according the cryptoglandular theory. A rare etiology is the pilonidal disease. In our case we observed a pilonidal disease mimicking an anterior perianal fistula, associated with another posterior anal fistula. CASE PRESENTATION: A 36-year old man was referred to our department with an anal fistula with an anterior opening. Despite the clinical examination and the endoanal ultrasound, only during the surgery we discovered the origin of the anterior fistula from a misdiagnosed pilonidal sinus. There was also a posterior anal fistula in communication with the same abscess of the anterior one. We performed a two-step surgery with a first fistulectomy of the anterior tract, a drainage of abscess and the positioning of a seton for the posterior fistula. After about one month and the fall of the seton we evaluate the good healing of posterior anal fistula and excised the residual pilonidal sinus. CONCLUSION: This misdiagnosed pilonidal disease created in our clinical report a true challenge. Our goal was to eliminate as much disease as possible, but also to avoid major complications or recurrences. We refused an aggressive approach and chose a two-step surgery, with in the first approach not only a demolitive time but also a reconstruction to facilitate healing, and in the second time the complete eradication of the pathology.

Nonsurgical treatment of Mason type II radial head fractures in athletes. A retrospective study.

OBJECTIVE: The best treatment for moderately displaced radial head fractures (Mason type II) still remains controversial. In cases of isolated fractures, there is no evidence that a fragment displacement of ≥ 2 mm gives poor results in conservatively treated fractures. PATIENTS AND METHODS: We retrospectively reviewed 52 patients (31M, 21F) affected by an isolated Mason type II fracture, treated with a long arm cast for two weeks between 2008 and 2013. All patients had practiced sports before being injured. They were all either bicyclists, or baseball, boxers, basketball, rugby, tennis or football players. The mean follow-up was 36 months. Elbow and forearm range of motion were measured. The Mayo Elbow Performance Score, the Broberg and Morrey rating system and the Disabilities of the Arm, Shoulder and Hand Score (DASH score) were analyzed. Follow-up radiographs were examined for evidence of consolidation, late displacement, early arthritis and non-unions. RESULTS: Flexion was slightly impaired in the injured limb when compared to the uninjured limb (137°± 6° versus 139°±5°) as were extension (-3°±6° versus 1°±4°, p < 0.05), supination (86°±6° versus 88°±3°), pronation (87°±4° versus 88°±6°) and valgus deviation (10°±4° versus 8°±3°, p < 0.05). 40 patients had no elbow complaints; 9 patients experienced occasional pain, 2 a mild instability of the elbow, and 4 a mild loss of grip strength. The DASH score was excellent in 48 patients (92.31%). In only 6 cases (11.53%) degenerative changes were greater in formerly injured elbows than in uninjured elbows. All patients returned to their previous sports activities. CONCLUSIONS: Isolated Mason type II fractures can have a good or excellent mid-term functional outcome even when treated conservatively.

Gastrointestinal stromal tumors treatment in the Imatinib era. The role of fair indication.

AIM: Gastrointestinal stromal tumor (GIST) is the most common mesenchymal tumor of the gastrointestinal tract. Surgery remains the elective treatment. We retrospectively compared two group of patients, who underwent surgery for GIST before and after Imatinib advent in order to analyze the recurrence and survival rate. METHODS: Two patient groups who underwent surgery for GIST, from January 1997 to December 2002 (Pre-Imatinib group) and from January 2003 to December 2008 (Post-Imatinib group) were compared. Patients were evaluated on the base of gender, age, clinical manifestations, primary location and metastasis positivity, tumor size, mitotic index, immunoreactivity for CD117 and the outcome, including date of death. RESULTS: In the Pre-IM group only one patient died for prostate cancer, 12 months after operation, the other died because of GIST with a 24.6 months of median survival rate (range 15-51). In the remaining 12 patients the median follow up period was 55 months (range 6-152 months). In the Post-IM group the mean follow up was 50.7 months (range 26-74) and they are still being assessed for oncological as well as surgical treatment. CONCLUSION: Early diagnosis and radical resection remain the standard of cure for GISTs. To date, the use of Imatinib lead to its utilization as adjuvant and neo-adjuvant therapy in adults. Our experience suggests that there is a correlation between the mutational status of KIT and clinical outcome. These aspects should be explored for targeted therapy that can effectively combine biological therapy to surgery.

[Open mesh technique versus laparoscopic transabdominal preperitoneal (TAPP) approach in inguinal hernia repair. Our experience]. / Tecnica open versus TAPP nel trattamento dell'ernia inguinale. Nostra esperienza.

BACKGROUND: In the last ten years the introduction of various open mesh and laparoscopic techniques has increased the interest in inguinal hernia surgery. Anyway controversy persists about the most effective inguinal hernia repair. The aim of this study was to compare the results of open mesh technique and laparoscopic transabdominal preperitoneal (TAPP) repair for inguinal hernia. PATIENTS AND METHODS: We considered 584 patients, 532 man and 52 woman, between 19 and 86 years: 332 (56.8%) had open mesh repair and 252 (43.2%) laparoscopic TAPP repair of groin hernia. Operative time, complications, recurrences and time to normal activities were recorded in both groups (range follow-up 1-10 years). RESULTS: The median operative time was 71 min for open group and 92 min for TAPP group. No intraoperative complications were observed. Postoperative complication rate was 4,5% in patients open group and 3% in TAPP group. The recurrence rate was less than 1% in both groups (0,6% for open repair and 0,4% for laparoscopic repair). Significant difference was observed in the median time to return to normal activities: 9,8 days in TAPP group versus 13,4 days in open approach. CONCLUSIONS: Our experience confirmed the safety and effectiveness of laparoscopic transabdominal preperitoneal (TAPP) approach to inguinal hernia repair as excellent alternative to conventional surgery. The reduction of operative time, complications and recurrences is correlated to the surgeon's experience and learning curve.

[Reoperative thyroid surgery: personal experience and review of the literature]. / Reinterventi in chirurgia tiroidea: contributo casistico e revisione della letteratura.

The goal of this study was to evaluate the complication rate of reoperative thyroid surgery and to find out the way to minimize the morbidity associated with it. We reviewed our experience in 622 patients, who underwent thyroid operation from January 2000 to September 2007. Among these ones, 76 were the patients who underwent reoperative thyroid surgery. Prior surgery in the 76 reoperations was: nucleo-resection in 9 pts (12.9%), lobectomy in 43 pts (55.5%), lobectomy+isthmectomy in 7 pts (9.3%), subtotal thyroidectomy in 17 pts (22.2%). Histologic examination revealed: benign lesions in 67 pts (88.15%), papillary cancer in 4 pts (5.26%), follicular cancer in 2 pts (2.63%), follicular adenoma in 1 pt (1.32%) and Hashimoto thyroiditis in 2 pts (2.63%). Complications included: section of recurrent laryngeal nerve, that was reconstructed in the same operation, and bilateral palsy of the recurrent laryngeal nerve so that was necessary to make a tracheotomy. One of the patient at the first thyroid surgery had monolateral palsy of the recurrent laryngeal nerve with dyspnoea and dysphonia. Temporary hypoparathyroidism (Ca<8 mg/dl) occurred in 47.3% of the patients, who underwent reoperative thyroid surgery and in 45.2% of the patients, who underwent prior thyroid surgery. Conclusions. This study documents that reoperative thyroid surgery can be performed with little morbidity to the patient if precise operative rules are respected.

[Adenocarcinoma of the appendix. A case report and review of the literature]. / L'adenocarcinoma dell'appendice ileo-ciecale: presentazione di un caso clinico e revisione della letteratura.

Primary adenocarcinoma of the appendix is a rare malignancy that constitutes less than 0.5% of all gastrointestinal neoplasms. Usually the diagnosis is made only after histological examination of surgically removed inflamed appendix. Alternatively represent an unexpected finding, confirmed by frozen section, during surgery performed for acute appendicitis or other non appendiceal pathologies. Natural history is strongly influenced by anatomic peculiarities of the appendix that predispose to early spread and perforation. Frequently is associated with synchronous and metachronous colorectal or extraintestinal cancers. The correct management is the right hemicolectomy as a primary procedure in the case of preoperatively or intraoperatively diagnosis or as secondary procedure, after two-three weeks from appendectomy, when the microscopic examination of specimen reveals the presence of adenocarcinoma. Right hemicolectomy is the best treatment for all histologic types (colonic, mucinous, adenocarcinoid), in presence of perforation and even in Dukes A tumors. A careful intraoperative search for synchronous lesions and a life-long program of surveillance for the detection of early stage metachronous carcinomas are recommended. The Authors report a case of primary adenocarcinoma of the appendix occurred in a 78 year-old female patient, diagnosed incidentally during surgery performed for ileus from suspected cecal neoplasm.

Laparoscopic versus open colectomy for obstructing right colon cancer: A systematic review and meta-analysis.

BACKGROUND: Hemicolectomy is the treatment of choice for intestinal obstruction from right colon cancer. This review compares the laparoscopic vs open access in hemicolectomy for patients with right colon cancer. METHODS: A systematic review and meta-analysis of clinical studies published after January 2017 was performed according to the Prisma guidelines. The study has been recorded on the Prospero register (CRD42016044108). RESULTS: Five studies were included for review. Only one anastomotic leak was reported in conventional open anastomosis group (1.9%) and none of the studies included in the meta-analysis reported re-operations during the first 30 postoperative days. The 30-day postoperative mortality did not differ between the two groups. The length of incision, blood loss, early mobilization after surgery, the 30-day postoperative overall complication rate and hospital length of stay were significantly shorter in the laparoscopic group. The difference in the duration of procedure was statistically significant in favor of the open group. The number of dissected lymph nodes, the overall survival at 5 years and time to flatus were described only in one study, without any significant difference. Finally, none of the trials reported any information concerning differences in the costs between the two techniques. CONCLUSIONS: The better outcomes described in this study achieved with laparoscopy, must be interpreted with caution because of the small number of patients involved, the selection and publication bias and the low level of evidence of the analysed trials. Indeed, the advantages of a minimally invasive approach, which have been demonstrated by the present meta-analysis, should encourage the use of laparoscopy also in emergency setting.

[Parathyroid carcinoma: clinical case and review of the literature]. / Carcinoma paratiroideo: caso clinico e revisione della letteratura.

INTRODUCTION: Parathyroid carcinoma is a rare endocrine neoplasm, difficult to define clinically and histopathologically. CASE REPORT: The case concerns of a 20 years old male with situs viscerum inversus (with dextrocardia), and symptoms: asthenia, oliguresis, nausea, emesis, myalgia, lower limb paresthesia and very high levels of calcium and PTH. Laboratory findings (PTH 580 pg/ml; Ca 12.40 mg/dl; P 1.9 mg/dl), echography, TC, and parathyroid scintigraphy, associated with clinical data, have suggested hypothesis of parathyroid carcinoma confirmed by histological examination and immunochemistry. Surgery was efficacious with normalization of Calcium and PTH levels, and disappearance of symptoms. After two years no signs of local recurrence were present, but imaging show pulmonary micronodulations of uncertain pathological meaning. DISCUSSION AND CONCLUSION: No clinical or bio-humoral data allows a preoperative diagnosis of parathyroid carcinoma. Only with definitive pathology and immunohistochemistry it is possible to differentiate an adenoma from a carcinoma. Surgery is the only effective therapy and therefore should be always performed. This neoplasm usually relapses, locally first and later with distant metastases. For this reason after surgery the patients should always undergo a strict follow-up programme including evaluation of PTH and calcemia.

[Complicated diverticular disease. Three cases of colovesical fistulas and review of literature]. / La malattia diverticolare complicata: le fistole colo-vescicati. Presentazione di tre casi clinici e revisione della letteratura.

Colovesical fistulas represent a possible less frequent complication of diverticular disease of colon. They represent a complex condition because of the possible and unexpected evolution into a septic shock with a high risk of death. The Authors report three cases of colovesical fistula as a complication of diverticular disease. They underline the importance of early diagnosis, specific antibiotic therapy and appropriate surgical therapy realized in one or two stages according to general and local conditions of each patient.

[A fecal fistula in patient who underwent an abdomino-perineal resection with a continent magnetic prosthesis: observations on an obsolete technique]. / Fistola stercoracea in paziente sottoposta ad intervento di Miles e portatrice di protesi magnetica: considerazioni su una tecnica obsoleta.

The Authors consider a case of a patient who underwent an abdominal-perineal resection and presented a fecal fistula as a late complication of a magnetic prosthesis implant. After a revision of the literature, the Authors evaluate the reasons for abandoning this surgical technique of continence many years ago, underlying not only the complications observed during the experimentation but also the lack of those benefits for which this technique was proposed.

[Pelvic abscesses. Treatment modalities and personal experience]. / Gli ascessi pelvici. Modalità di trattamento ed esperienza personale.

The pelvic abscesses as complication of surgical operations or various pathologies is a delicate clinical situation because of the possible and unexpected evolution into a settic shock with a high risk of death. The authors report their personal experience of 16 cases undergone surgical treatment. They underline the importance of an early diagnosis, of a control of the patient general conditions with a specific antibiotic therapy, of the possibility to treat this pathology in a percutaneous way with the help of radiologic techniques or eventually by surgery.

Prevention of complications during reoperative thyroid surgery.

BACKGROUND: Thyroidectomy performed by an experienced surgeon is associated with a low incidence of recurrent laryngeal nerve injury and permanent hypoparathyroidism. During reoperative thyroid surgery there is a higher technical risk because detection and preservation of the recurrent laryngeal nerves and parathyroid glands are more difficult than in the primary surgery. AIM: Our retrospective cohort study was to assess short- and long-term complications associated with reoperative thyroid surgery in order to suggest a technical approach to lower the morbidity rate. MATERIALS AND METHODS: From January 2005 to September 2013, 745 patients underwent surgery for thyroid disease. Before surgery all patients underwent clinical examination, laboratory blood tests, hormonal assays, neck ultrasound, chest radiography and indirect laryngoscopy. Patients were followed up at 1, 3, 6 months and then annually after operation with hormonal assays, blood tests and neck ultrasound. RESULTS: Eighty (10.7%) out of 745 patients (mean-age= 52.5 years; age-range 18-80) underwent reoperative surgery for recurrent thyroid disease. The primary treatments were enucleoresection (11.2%), thyroid lobectomy(56,3%), thyroid lobectomy with isthmectomy(10%) and subtotal thyroidectomy (22,5%). In the reoperative surgery group (Group Re) the transient RLN complications were 1.3% compared to 0.2% in the primary surgery group (Group P) (p= 0.51). The incidence of temporary hypocalcemia was 45% in the reoperative surgery group vs. 42.7% in the primary surgery group (p=0.72). CONCLUSIONS: Reoperative surgery should be reserved to experienced surgeons. However, even in this case, when surgical maneuvers reserved for primary surgery are applied, then this surgery is associated with a low complications rate.
