Robotic resection compared with laparoscopic rectal resection for cancer: systematic review and meta‐analysis of short‐term outcome

Aim  The study aimed to compare robotic rectal resection with laparoscopic rectal resection for cancer. Robotic surgery has been used successfully in many branches of surgery but there is little evidence in the literature on its use in rectal cancer.

Laparoscopic vs open resection for rectal cancer: a meta‐analysis of randomized clinical trials

Aim  Laparoscopic and open rectal resection for cancer were compared by analysing a total of 26 end points which included intraoperative and postoperative recovery, short‐term morbidity and mortality, late morbidity and long‐term oncological outcomes.

Elective sigmoid colectomy for diverticular disease. Laparoscopic vs open surgery: a systematic review

Aim  A meta‐analysis of nonrandomized studies and one randomized trial was conducted to compare laparoscopic surgery with open surgery in the elective treatment of patients with diverticular disease.

Fibrin glue in the treatment of anal fistula: a systematic review.

BackgroundNew sphincter-saving approaches have been applied in the treatment of perianal fistula in order to avoid the risk of fecal incontinence. Among them, the fibrin glue technique is popular because of its simplicity and repeatability. The aim of this review is to compare the fibrin glue application to surgery alone, considering the healing and complication rates.MethodsWe performed a systematic review searching for published randomized and controlled clinical trials without any language restriction by using electronic databases. All these studies were assessed as to whether they compared conventional surgical treatment versus fibrin glue treatment in patients with anal fistulas, in order to establish both the efficacy and safety of each treatment. We used Review Manager 5 to conduct the review.ResultsThe healing rate is higher in those patients who underwent the conventional surgical treatment (P = 0,68), although the treatment with fibrin glue gives no evidence of anal incontinence (P = 0,08). Furthermore two subgroup analyses were performed: fibrin glue in combination with intra-adhesive antibiotics versus fibrin glue alone and anal fistula plug versus fibrin glue. In the first subgroup there were not differences in healing (P = 0,65). Whereas in the second subgroup analysis the healing rate is statistically significant for the patients who underwent the anal fistula plug treatment instead of the fibrin glue treatment (P = 0,02).ConclusionIn literature there are only two randomized controlled trials comparing the conventional surgical management versus the fibrin glue treatment in patients with anal fistulas. Although from our statistical analysis we cannot find any statistically significant result, the healing rate remains higher in patients who underwent the conventional surgical treatment (P = 0,68), and the anal incontinence rate is very low in the fibrin glue treatment group (P = 0,08). Anyway the limited collected data do not support the use of fibrin glue. Moreover, in our subgroup analysis the use of fibrin glue in combination with intra-adhesive antibiotics does not improve the healing rate (P = 0.65), whereas the anal fistula plug treatment compared to the fibrin glue treatment shows good results (P = 0,02), although the poor number of patients treated does not lead to any statistically evident conclusion. This systematic review underlines the need of new RCTs upon this issue.

Antibiotic prophylaxis in thyroid surgery: a preliminary multicentric italian experience

Post-operatory wound infections are a very uncommon finding after thyroidectomy. For these reasons international guidelines do not routinely recommend systemic antibiotic prophylaxis.The benefits of this antibiotic prophylaxis is not supported by clinical evidence in the literature. We have conducted a multicentric randomized double-blind trial on 500 patients who had undergone thyroidectomy for goitre or thyroid carcinoma. The 500 patients enrolled in the study (mean age 47 years) were randomized in two subgroups of 250 patients. 250 patients were treated with standard antibiotic prophylaxis with sulbactam/ampicillin 1 fl (3 gr.) 30 min before surgery. No antibiotic prophylaxis was instituted in the remainder 250 patients. Our RCT showed that prophylactic antibiotic treatment is not beneficial in patients younger than eighty years old, with no concomitant metabolic, infective and hematologic disease, with no cardiac valvulopathies, not under steroidal or immunosuppressive treatment, and not severely obese. Our study should be regarded only as a preliminary RCT, and should be followed by a study in which a larger number of patients should be enrolled so that statistically significant data can be obtained.

The sigmoid volvulus: surgical timing and mortality for different clinical types

BackgroundIn western countries intestinal obstruction caused by sigmoid volvulus is rare and its mortality remains significant in patients with late diagnosis. The aim of this work is to assess what is the correct surgical timing and how the prognosis changes for the different clinical types.MethodsWe realized a retrospective clinical study including all the patients treated for sigmoid volvulus in the Department of General Surgery, St Maria Hospital, Terni, from January 1996 till January 2009. We selected 23 patients and divided them in 2 groups on the basis of the clinical onset: patients with clear clinical signs of obstruction and patients with subocclusive symptoms. We focused on 30-day postoperative mortality in relation to the surgical timing and procedure performed for each group.ResultsIn the obstruction group mortality rate was 44% and it concerned only the patients who had clinical signs and symptoms of peritonitis and that were treated with a sigmoid resection (57%). Conversely none of the patients treated with intestinal derotation and colopexy died. In the subocclusive group mortality was 35% and it increased up to 50% in those patients with a late diagnosis who underwent a sigmoid resection.ConclusionsThe mortality of patients affected by sigmoid volvulus is related to the disease stage, prompt surgical timing, functional status of the patient and his collaboration with the clinicians in the pre-operative decision making process. Mortality is higher in both obstructed patients with generalized peritonitis and patients affected by subocclusion with late diagnosis and surgical treatment; in both scenarios a Hartmanns procedure is the proper operation to be considered.

Rectal washout and local recurrence in rectal resection for cancer: a meta-analysis.

Aim  The effectiveness of rectal washout was compared with no washout for the prevention of local recurrence after anterior rectal resection for rectal cancer.

Efficacy of surgery and imatinib mesylate in the treatment of advanced gastrointestinal stromal tumor: a systematic review

AIMS AND BACKGROUND In patients with localized gastrointestinal stromal tumors, surgery remains the elective treatment. Nowadays, imatinib therapy has been standardized in advanced gastrointestinal stromal tumors, showing continuous improvements in progression-free and overall survival. A combination of imatinib therapy and surgery may also be effective in a subset of patients with metastatic or unresectable gastrointestinal stromal tumors. In this review, the authors analyzed the role of imatinib mesylate associated to surgery in unresectable and/or metastatic gastrointestinal stromal tumors. METHODS AND STUDY DESIGN We searched for all published and unpublished randomized controlled clinical trials and controlled clinical trials. We conducted the review according to the recommendations of The Cochrane Collaboration. We used Review Manager 5 software for the statistical analysis. RESULTS There are currently no randomized controlled clinical trials or controlled clinical trials on this issue. We performed a subgroup analysis in the patients preoperatively treated with imatinib mesylate. This subgroup revealed a minor incidence of recurrent or metastatic gastrointestinal stromal tumors and a greater incidence of locally unresectable gastrointestinal stromal tumors in the responsive disease group (P = 0.001). In this patient group, more complete resections were observed (P = 0.00001). Furthermore, in the same patient group we observed a more significant 12 and 24-month disease-free survival after imatinib treatment and complete resection (respectively P= 0.06 and P= 0.003) and also a better 24-month overall survival (P = 0.004). CONCLUSIONS There is actually only one ongoing European randomized study evaluating surgery of residual disease in patients with metastatic gastrointestinal stromal tumors responding to imatinib mesylate. Imatinib mesylate represents the standard treatment as preoperative supplement for locally unresectable and/or metastatic gastrointestinal stromal tumors, and a trial to compare the approach versus surgery alone is not necessary. For patients responding to imatinib or patients with prolonged stable disease, resection of residual disease should be considered. A phase III randomized study evaluating surgery of residual disease in patients with metastatic gastrointestinal stromal tumor responding to imatinib mesylate, EORTC 62063, has been opened. Moreover, surgery should be considered for patients at higher risk of complications during pharmacological debulking. In advanced gastrointestinal stromal tumors, the advantages of the integrated treatment are significant in the complete or partial response disease group in terms of more complete resections and better disease-free and overall survival.

Ghost ileostomy after anterior resection for rectal cancer: a preliminary experience.

PurposeThe aim of this study was to describe and evaluate the feasibility and the eventual advantages of ghost ileostomy (GI) versus covering stoma (CS) in terms of complications, hospital stay and quality of life of patients and their caregivers after anterior resection for rectal cancer.MethodsIn this prospective study, we included patients who had rectal cancer treated with laparotomic anterior resection and confectioning a stoma (GI or CS), in the period comprised between January 2008 and January 2009. Short-term and long-term surgery-related mortality and morbidity after primary surgery (including that stoma-related and colorectal anastomosis-related) and consequent to the intervention of intestinal recanalization (CS group) and GI closure were evaluated. We evaluated hospital stay and quality of life of patients and their caregivers.ResultsStoma-related morbidity rate was higher in the CS group than in GI group (37% vs. 5.5%, respectively, P = 0.04). Morbidity rate after intestinal recanalization in the CS group was 25.9% and 0% after GI closure (P = 0.08). Overall stoma morbidity rate was significantly lower in the GI group with respect to CS group (5.5% vs. 40.7%, respectively, P = 0.03). CS group was characterized by a significantly longer recovery time (P = 0.0002). Caregivers and stoma-related quality of life were better in the GI group than in CS group (P < 0.0001 and P = 0.0005, respectively).ConclusionsGI is feasible, characterized by shorter recovery, lesser degree of total, as well as anastomosis-related morbidity and higher quality of life of patients and the caregivers in respect to CS. We suggest that GI (should be evaluated as an alternative to conventional ileostomy) could be indicated in selected patients that do not present risk factors, but require caution for anastomotic leakage for the low level of colorectal anastomosis.

Ovarian hydatid cyst: A case report

Discovering an hydatid cyst in pelvic region, especially as primary localization, is a rare event; as a matter of fact according to data provided by literature the incidence is between 0.2 and 2.25%. The ovarian involvement is often secondary to a cysts dissemination localized in a different site. When possible the optimal treatment is represented by radical laparotomic cystectomy. We report a case of an old woman affected by this pathology that we have treated with a cysts marsupialization after a draining and irrigation of cyst cavity with hypertonic saline solutions.
