Anatomical and Functional Features of the Internal Rectal Prolapse With Outlet Obstruction Determined With 3D Endorectal Ultrasonography and High-Resolution Anorectal Manometry: An Observational Case-Control Study.

OBJECTIVES: To investigate correlation between rectal wall thickness (RWT) and anorectal pressures, in obstructed defecation syndrome (ODS) patients caused by internal rectal prolapse. METHODS: ODS patients and healthy volunteers (HVs) underwent 3D endorectal ultrasound (3D-EUS) and high-resolution anorectal manometry (HRAM); RWT, total rectal wall volume (TRWV), pushing endorectal pressure (PEP), recto-anal gradient were determined RESULTS: We enrolled 35 ODS patients and 25 HVs. Patients showed markedly decreased TRWV, PEP, and recto-anal gradient. Linear correlation was found between markedly reduced TRWV and markedly hypotonic PEP. CONCLUSIONS: HRAM and 3D-EUS could be performed in ODS assessment, to better understand rectal function.

Is Percutaneous Transhepatic Biliary Drainage Better than Endoscopic Drainage in the Management of Jaundiced Patients Awaiting Pancreaticoduodenectomy? A Systematic Review and Meta-analysis.

PURPOSE: To compare postoperative complications in patients who underwent pancreatoduodenectomy after either endoscopic or percutaneous biliary drain (BD). MATERIAL AND METHODS: Data from studies comparing the rate of postoperative complications in patients who underwent endoscopic BD or percutaneous BD before pancreatoduodenectomy were extracted independently by 2 investigators. The primary outcome compared in the meta-analysis was the risk of postoperative complications. Secondary outcomes were the risks of procedure-related complications, postoperative mortality, postoperative pancreatic fistula, severe complications, and wound infection. For dichotomous variables, the odds ratio (OR) with 95% confidence interval (CI) was calculated. RESULTS: Thirteen studies, including 2334 patients (501 in the percutaneous BD group and 1833 in the endoscopic group), met the inclusion criteria. Postoperative and procedure-related complication rates were significantly lower in the percutaneous BD group (OR = .7, 95% CI = .52-.94, P = .02 and OR = .44, 95% CI = .23-.84, P = .01, respectively). No significant differences were observed when severe postoperative complications, postoperative mortality, postoperative pancreatic fistula, and wound infection rates were compared. CONCLUSIONS: In patients awaiting pancreatoduodenectomy, preoperative percutaneous BD is associated with fewer procedure-related or postoperative complications than endoscopic drain.

Long-term functional follow-up after anterior rectal resection for cancer.

PURPOSE: This is a retrospective analysis including all of the patients that have undergone anterior resection for rectal cancer from January 1998 to December 2005 in two tertiary referral centers. The study aims to evaluate the long term functional results after low anterior resection and to identify the risk factors of postoperative bowel disorders. METHOD: Data were collected from the clinical records, and then the low anterior resection syndrome score which is a specific questionnaire to investigate the symptoms after surgery was submitted to the selected patients. Exclusion criteria were intra-abdominal rectal cancer, partial mesorectal excision, permanent stoma, recurrent local disease, and patients who declined the questionnaire. RESULTS: A total of 93 patients were included in the analysis with a median age at the diagnosis of 66 years. The median follow-up was 13.7 years, and low anterior resection syndrome was reported in 44 patients (47.5 %), with major manifestations in 19 patients (20.5 %), and minor symptoms in 25 patients (27 %). Age more than 70 years, tumor distance from the external anal verge, neoadjuvant treatment, and interval time of closing stoma are independent prognostic factors of functional disorders after surgery. CONCLUSIONS: Because of its great impact on the quality of life of these patients, it is necessary to early identify the syndrome trying to reduce its manifestations. Moreover, the symptoms seem to remain stable 1 year after surgery; hence, it is important to have an exhaustive, preoperative counseling and an integrated post-operative functional and rehabilitational follow-up in association with the oncologic pathway.

Quality of life and scar evolution after negative pressure or conventional therapy for wound dehiscence following post-bariatric abdominoplasty.

No studies have examined scars and quality of life after different treatments of wound dehiscence in patients undergoing post-bariatric abdominoplasty. Scars and quality of life of patients with postoperative wound dehiscence managed with negative pressure wound therapy (group A) and conventional wound therapy (group B) were reviewed 6 months after wound healing. Of 38 patients undergoing treatment for wound dehiscence after 203 abdominoplasty, 35 (group A = 14 versus group B = 21) entered the study. Wound healing in group A was significantly faster than group B (P = 0·001). Patients (P = 0·0001) and observers (P = 0·0001) reported better overall opinions on a scar assessment scale for group A. Better overall quality of life and general health satisfaction were observed in group A (P < 0·05). A significant correlation was observed between the World Health Organization Quality of Life scores and Patient and Observer Scar Assessment Scale scores (r=-0·68, P < 0·0001) in all 35 patients. Negative pressure wound therapy is feasible and effective in patients with wound dehiscence following post-bariatric abdominoplasty. An adequate post-treatment outcome is achieved compared with conventional wound therapy in light of a strong association found between worse patient scar self-assessment and poor overall quality of life, regardless of the received treatment.

A Gelatin-Thrombin Matrix Topical Hemostatic Agent (Floseal) in Combination With Harmonic Scalpel Is Effective in Patients Undergoing Total Thyroidectomy: A Prospective, Multicenter, Single-Blind, Randomized Controlled Trial.

BACKGROUND: Hemostasis during thyroidectomy is essential; however, the safest, most efficient, and most cost-effective way to achieve this is unclear. This randomized, multicenter, single-blind, prospective study evaluated the efficacy and safety of using different hemostatic approaches in patients undergoing total thyroidectomy. METHODS: Patients aged ≥18 to 70 years were randomized to Floseal + a harmonic scalpel (HS), Floseal alone, HS alone, or standard total thyroidectomy. Primary endpoint was 24-hour drain output. Secondary endpoints included surgery duration and complications. RESULTS: Two hundred and six patients were randomized to Floseal + HS (n = 52), Floseal alone (n = 54), HS alone (n = 50), and standard total thyroidectomy (n = 50). The 24-hour drain output was lower in the Floseal + HS group compared with standard thyroidectomy. Floseal + HS also had a shorter surgery time (P < .0001) versus the other 3 treatments. CONCLUSION: Floseal + HS can be effective at reducing postsurgical drain output and provides a complementary hemostatic approach in patients undergoing total thyroidectomy.

The patterns of reflux can affect regression of non-dysplastic and low-grade dysplastic Barrett's esophagus after medical and surgical treatment: a prospective case-control study.

BACKGROUND: To date, therapeutic guidelines and pattern of reflux for patients with no-dysplasia (ND) or low-grade dysplasia (LGD) Barrett's esophagus (BE) remain unclear. We aimed to analyze pattern of reflux and regression of ND- or LGD-BE after medical and surgical treatment. METHODS: We studied a cohort of ND- and LGD-BE patients who underwent laparoscopic total fundoplication and a cohort of ND- and LGD-BE patients managed medically. Patients were matched for age, sex, and disease duration. After 1 year of follow-up at least, all patients underwent upper endoscopy with esophageal biopsies to evaluate any histological changes, as well as manometry and impedance-pH-metry to re-assess reflux patterns. RESULTS: Thirty-seven patients (20 LGD, 17 ND) undergoing laparoscopic fundoplication were enrolled and compared with 25 patients (13 LGD, 12 ND) managed with proton pump inhibitors (PPI). Laparoscopic fundoplication resulted in a better control of both acidic and weakly acidic reflux (P < 0.001) and was associated with a higher probability of reversion for LGD (P < 0.01). Esophageal motility did not differ between surgically and medically treated patients. CONCLUSIONS: In patients with ND- or LGD-BE, laparoscopic fundoplication seems to warrant a better control of all kinds of refluxate and it is associated with a higher likelihood of reversion of both LGD- and ND-BE, compared with PPI therapy.

D-shape asymmetric excision of sacrococcygeal pilonidal sinus with primary closure, suction drain, and subcuticular skin closure: an analysis of risks factors for long-term recurrence.

BACKGROUND: Few studies have reported long-term recurrence rates after asymmetric excision with primary closure in the treatment of sacrococcygeal pilonidal disease. METHODS: A retrospective analysis of a prospectively maintained database of 550 surgical excisions performed for sacrococcygeal pilonidal disease between 1988 and 2005 was performed. RESULTS: A total of 550 patients with a diagnosis of pilonidal sinus underwent surgical excision over a period of 17 years. Thirty-eight out of the 550 patients (3.5%) were lost at follow-up. At a mean follow up of 11.2 ± 5.3 years, median 11 years (range = 3-22), the recurrence rate was 8.9%. Actuarial 1-, 5-, 10-, and 20-year disease-free survival rates were 98%, 94%, 92%, and 83%, respectively, with a median overall disease-free survival of 10 years (95% confidence interval [CI] = 3-15). When patients were stratified according to several variables known to influence recurrence, an age of less or ≥22 years (odds ratio [OR] = 1.5, 95% CI = 0.3-7.5, P = .001), a family history of sinus (OR = 5.9, 95% CI = 2.7-12, P = .0001), and intraoperative methylene blue use (OR = 6.3, 95% CI = 1.2-31, P = .024) were indicated as independent predictors of disease-free survival rates. CONCLUSIONS: D-shape asymmetric excision and scar lateralization, with primary multilayer subcuticular closure, suction drain insertion, and skin closure in patients with sacrococcygeal pilonidal disease is a safe and adequate surgical treatment offering an effective healing rate as well as low recurrence. Several features are likely to predict a better or a worse long-term recurrence rate in patients undergoing surgery for sinus pilonidalis.

Laparoscopic Drainage as First Line Treatment for Complex Pyogenic Liver Abscesses.

UNLABELLED: Background/aims: Pyogenic liver abscess (PLA) is a rare but potentially fatal condition if untreated. In available retrospective series successful rate of per- cutaneous drainage (PD) on large multiloculated PLA, that has been definited "complex". In this observation- al study, we report the experience of our Institution in performing laparoscopic drainage of complex liver ab- scess over a 5-years period as first line treatment for selected cases of PLA. Methodology: All cases of large multiloculated liver abscesses admitted to the General and Hepatobiliary Surgery of "Loreto Nuovo" Hospital Naples, Italy over the last 5-years period were treated by laparoscopic drainage and his clinicopathological variables were retrospectively reviewed. RESULTS: Ten patients with large multiloculated liver abscess has been admitted and treated by only laparoscopic drainage without need of other perioperative procedures. Mean age was 51.5 years (range 41-75y); average hospital stay was 4.6 days (range 2-6 days) and major postoperative morbidity or deaths were not registered. Successful rate was 100% with no recurrence at 2-years follow up (range 12/38 months). CONCLUSIONS: Laparoscopic drainage seems to be a safe and reproducible mini-invasive treatment of complex liver abscesses and to offer advantages over percutaneous and surgical open approach.

Axillary lymphadenectomy for breast cancer in elderly patients and fibrin glue.

BACKGROUND: Axillary lymphadenectomy or sentinel biopsy is integral part of breast cancer treatment, yet seroma formation occurs in 15-85% of cases. Among methods employed to reduce seroma magnitude and duration, fibrin glue has been proposed in numerous studies with controversial results. METHODS: Thirty patients over 60 years underwent quadrantectomy or mastectomy with level I/II axillary lymphadenectomy; a suction drain was fitted in all patients. Fibrin glue spray were applied to the axillary fossa in 15 patients; the other 15 patients were treated with harmonic scalpel. RESULTS: Suction drainage was removed between post-operative Days 3 and 4. Seroma magnitude and duration were not significant in patients receiving fibrin glue compared with the harmonic scalpel group. CONCLUSIONS: Use of fibrin glue does not always prevent seroma formation, but can reduce seroma magnitude, duration and necessary evacuative punctures.

The impact of age and oral calcium and vitamin D supplements on postoperative hypocalcemia after total thyroidectomy. A prospective study.

BACKGROUND: Hypocalcemia caused by transient or definitive hypoparathyroidism is the most frequent complication after total thyroidectomy (TT). We aimed to compare the impact of age and the clinical usefulness of oral calcium and vitamin D supplements on postoperative hypocalcemia after TT, and to determine which risk factors are important for hypocalcemia incidence. METHODS: Two hundred consecutive patients treated by TT were included prospectively in the present study. All patients supplemented oral calcium and vitamin D in the post-operative time. The data concerning symptomatic and laboratoristichypocalcemia were collected. RESULTS: Symptomatic hypocalcemia developed only in 19 patients (9.5%), whereas laboratory hypocalcemia developed in 36 patients (18%). The risk for postoperative hypocalcemia was increate 20-fold for patients older than 50 years. CONCLUSIONS: Age is significantly associated with postoperative hypocalcemia. Implementing oral calcium and vitamin D after total thyroidectomy can reduce the incidence of hypocalcemia related to surgery.

Laparoscopic and open surgical treatment of left-sided pancreatic lesions: clinical outcomes and cost-effectiveness analysis.

BACKGROUND: Previous studies comparing open distal pancreatectomy (ODP) and laparoscopic distal pancreatectomy (LDP) have found advantages related to minimal-access surgery. Few studies have compared direct and associated costs after LDP versus ODP. The purpose of the current study was to compare perioperative outcomes of patients undergoing LDP and ODP and to assess whether LDP was a cost-effective procedure compared with the traditional ODP. METHODS: A retrospective analysis of a prospectively maintained database of 52 distal pancreatic resections that were performed during a 10-year period was performed. RESULTS: Patients included in the analysis were 16 in the LDP group and 29 in the ODP. Tumors operated laparoscopically were smaller than those removed at open operation, but the length of pancreatic resection was similar. The mean operating time for LDP was longer than ODP (204 ± 31 vs. 160 ± 35; P < 0.0001), whereas blood loss was higher in the open group (365 ± 215 vs. 160 ± 185, P < 0.0001). Morbidity (25 vs. 41; P = 0.373) and pancreatic fistula (18 vs. 20%; P = 0.6) rates were similar after LDP and ODP, as was 30-day mortality (0 vs. 2%; P = 0.565). LDP had a shorter mean length of hospital stay than ODP (6.4 (2.3) vs. 8.8 (1.7) days; P < 0.0001). Operative cost for LDP was higher than ODP (2889 vs. 1989; P < 0.0001). The entire cost of the associated hospital stay was higher in the ODP group (8955 vs. 6714; P < 0.043). The total cost was comparable in LDP and ODP groups (9603 vs. 10944; P = 0.204). CONCLUSIONS: Laparoscopic distal pancreatectomy for left-sided lesions can be performed safely and effectively in selected patients, with reduced hospital stay and operative blood loss. Major complications, including pancreatic leak, were not reduced, whereas total cost was comparable between LDP and ODP. A selective use of LDP seems to be an effective and cost-efficient alternative to ODP.

Laparoscopic liver resection for hepatocellular carcinoma in cirrhosis: long-term outcomes.

BACKGROUND: Few data regarding survival or pattern of recurrence after laparoscopic liver resection (LLR) for hepatocellular carcinoma (HCC) on cirrhosis have been reported so far. METHODS: A retrospective analysis of a prospectively maintained database of 109 laparoscopic interventional procedures performed for HCC in cirrhotic liver between 2000 and 2008 was conducted. RESULTS: Sixty-five patients underwent an LLR. Morbidity rates were 20% (13/65), whereas there was only 1 death (1.5%). Reoperation was required in 2 patients. The overall mean postoperative hospital stay was 8.2 (2.6; 3-15) days. The actuarial overall 1-, 3-, and 5-year survival rates were 95, 70, and 55%, respectively, with a median overall survival of 75 months. Excluding the one hospital death, the actuarial 1-, 3-, and 5-year disease-free survival rates were 81, 62, and 32%, respectively, with a median overall disease-free survival of 42 months (95% confidence interval, CI: 18-65). On multivariate analysis, tumor grade (OR: 3.5, 95% CI: 1.1-10.7, p = 0.026) and microvascular invasion (OR: 4.9, 95% CI: 1.2-18.8, p = 0.020) resulted as independent predictors of overall survival. On multivariate analysis, gender (OR: 3.4, 95% CI: 1.1-10.2, p = 0.023), satellite tumor (OR: 4.3, 95% CI: 1.5-12.3, p = 0.006), microvascular invasion (OR: 3.3, 95% CI: 1.0-10.1, p = 0.036) and surgical margin (OR: 3.7, 95% CI: 1.0-10.1, p = 0.036) were identified as independent prognostic predictors of better disease-free survival. After a median follow-up of 29 (range 3-81) months, 31 (48%) out of 64 patients had recurrence. The cumulative recurrence rates at 1, 3, and 5 years were 19, 39, and 68%, respectively. CONCLUSION: This prospective observational study has confirmed the feasibility and safety of LLR in selected patients with HCC in cirrhotic liver, and proved that it can warrant long-term outcome similar to those reported with the traditional open approach.

Single port laparoscopic cholecystectomy: a new evolving technique.

Although multiple groups have reported initial success with single port laparoscopy, no consensus exists concerning the technical aspect of this surgery. In this report, we describe in detail our technique to perform single port laparoscopic cholecystectomy. Twelve cases of single port laparoscopic cholecystectomy for gallbladder stones were performed in our surgical unit. There was only one conversion during the first operation of the series to standard laparoscopy, and never to open operation. No intraoperative adverse events or major perioperative complications were reported. All the patients have been discharged within 48 hours, with uneventful postoperative course, nearly painless, without any discomfort and no visible scar. Single port laparoscopic surgery is a promising option for the treatment of gallbladder stones providing that technical and oncological surgical principles are respected.

The effect of pelvic septic complications on function and quality of life after ileal pouch-anal anastomosis: a single center experience.

Ileal pouch-anal anastomosis (IPAA) has become the procedure of choice for surgical treatment of intractable ulcerative colitis (UC). Surgical complications occurring in the short-term, like pelvic sepsis, are responsible for pouch dysfunction. We prospectively evaluated 118 patients with IPAA for UC operated on between 1987 and 2002. Follow-up intervals were at 3, 6, and 12 months in the first year, then every year for at least 5 years. Patients answered a questionnaire 1 and 5 years after ileostomy closure. One hundred and seventeen patients completed the early follow-up. Nine patients developed early pelvic sepsis (7.69%); six required pouch salvage procedure. In about 33.3 per cent of cases more than one procedure was necessary. Eighty-eight patients were available for 5-year functional evaluation. Patients developing early sepsis (n = 9) showed worse long-term functional results compared with the remaining study population (n = 79): stool frequency; night evacuation; perfect day/night continence; discrimination; antidiarrhoeals need; pad usage; and sexual restriction were significantly different (P < 0.05). Quality of life and satisfaction after surgery were good in all patients. This observation did not correlate with function. Eighty-eight and 97 per cent would undergo IPAA again and would recommend it to others respectively, in septic group and controls. Functional outcome after IPAA may be influenced by early septic complications. Overall quality of life and satisfaction with surgery are comparable with those of controls.

Treatment of complex perianal fistulas in Crohn disease: infliximab, surgery or combined approach.

BACKGROUND: The aim of this study was to compare the outcomes of the management of perianal fistulas in Crohn disease between infliximab, surgery or a combination of surgery and infliximab. METHODS: We prospectively subdivided 35 consecutive patients with Crohn disease with complex perianal fistulas into 3 groups: 11 patients received infliximab (5 mg/kg intravenously at 0, 2 and 6 wk; group A), 10 underwent surgery (group B) and 14 received a combination of surgery and postoperative infliximab (group C). We evaluated the rate and time of healing of perianal fistulas, the rate of recurrences and time to relapse at a median follow-up of 18.8 (standard deviation [SD] 10.8, range 8-38) months. RESULTS: The time to healing of fistulas was significantly shorter among patients who received surgery and infliximab than among those who received surgery alone (p < 0.05) and was close to statistically shorter among those who received both treatments than among those who received infliximab alone (p = 0.06). Patients who received surgery and infliximab had a significantly longer mean time to relapse (p < 0.05) than those who received infliximab (mean 2.6 [SD 0.7] mo) or surgery alone (mean 3.6 [SD 0.5] mo). CONCLUSION: We found better outcomes among patients who received a combination of surgery and infliximab therapy. These patients experienced a short time to healing of fistulas and significantly longer mean time to relapse of complex fistulas.

Laparoscopic redo surgery for recurrent hepatocellular carcinoma in cirrhotic patients: feasibility, safety, and results.

BACKGROUND: Recurrence of cancer and the need for several surgical treatments are the Achilles' heel of the treatment for hepatocellular carcinoma (HCC) in cases of cirrhosis. The difficulty of reintervention is increased by the formation of adhesions after the previous hepatectomy that can make a new surgical procedure more difficult and less safe. With a minimally invasive approach, the formation of postoperative adhesions seems to be minimized, and the adhesiolysis procedure seems to be faster and safer in terms of blood loss and risk of visceral injuries. METHODS: This report describes a series of 15 patients submitted to a laparoscopic reintervention (hepatic resection or radiofrequency ablation) for a recurrence of HCC after a previous open (group 1) or laparoscopic (group 2) procedure for a primary tumor. It aims to explain the feasibility, safety, and results of repeated laparoscopic liver surgery. RESULTS: The rates for overall postoperative mortality and morbidity were respectively 0% and 26.6% (4/15). No patients had a severe postoperative complication. Only one patient in group 2 presented with moderate ascites postoperatively, whereas two patients in group 1 reported atelectasis requiring physiotherapy and one experienced pneumonia, which was treated with antibiotics. In this series, the findings indicated that patients submitted first to an open hepatic resection (group 1) experience more intraabdominal adhesions. Moreover, in group 1, hypervascularized adhesions typical of cirrhotic patients were several and thicker, with a major potential risk of bleeding and bowel injuries at the time of reintervention. Although for group 2 the length of the intervention was shorter, for group 1, the operating times and safety in terms of bowel injuries were acceptable, demonstrating the feasibility of iterative laparoscopic surgery also for cirrhotic patients previously treated by the open surgical approach. The operative time for the second surgical procedure was shorter and the adhesiolysis easier for the patients previously treated with the laparoscopic approach (group 2). This underscores the advantages of the minimally invasive approach for managing the long oncologic history of cirrhotic patients. CONCLUSION: Laparoscopic redo surgery for recurrent HCC in cirrhotic patients is a safe and feasible procedure with good short-term outcomes, but further prospective studies are needed to support these results.

Laparoscopic hand-assisted right hemihepatectomy by ultrasound-directed intrahepatic approach.

BACKGROUND/PURPOSE: Laparoscopic hepatectomy is a promising option for patients affected by a liver mass, and the procedure is gaining popularity. Minor laparoscopic resections have been widely reported. In contrast, major laparoscopic hepatectomy has been performed in only a limited number of cases. Hand-assisted laparoscopic liver surgery has been advocated in order to improve liver exposure and vascular control and increase the safety of the procedure. Transparenchymal en-bloc transection of the right portal triad has been reported to be safe and useful in open surgery. METHODS: We describe a personal technique for hand-assisted right hemihepatectomy. With ultrasound guidance, the right hepatic pedicle is isolated intrahepatically and transected en bloc with a single firing of an endostapler. Parenchymal transection is carried out with ultrasonically activated or vessel-sealing devices together with endostaplers. RESULTS: The procedure was successfully accomplished in three patients. The Pringle maneuver was never performed. No intraoperative or postoperative complications occurred. CONCLUSION: This study is the first to report a technique of right hemihepatectomy that combines hand-assisted laparoscopy and an ultrasound-guided intrahepatic approach. This technique may be a useful option to simplify the operation, reduce operative time, and increase the safety of the procedure.
