RESUMO
Laparoscopy has already been validated for treatment of early gastric cancer. Despite that, no data have been published about the possibility of a minimally invasive approach to surgical complications after primary laparoscopic surgery. In this multicentre study, we describe our experience in the management of complications following laparoscopic gastrectomy for gastric cancer. A chart review has been performed over data from 781 patients who underwent elective gastrectomy for gastric cancer between January 1996 and July 2020 in two high referral department of gastric surgery. A fully descriptive analysis was performed, considering all the demographic characteristics of patients, the type of primary procedure and the type of complication which required reoperation. Moreover, a logistic regression was designed to investigate if either the patients or the primary surgery characteristics could affect conversion rate during relaparoscopy. Fifty-one patients underwent reintervention after elective laparoscopic gastric surgery. Among patients who received a laparoscopic reintervention, 11 patients (34.3%) required a conversion to open surgery. Recovery outcomes were significantly better in patients who completed the reoperation through laparoscopy. Relaparoscopy is safe and effective for management of complications following laparoscopic gastric surgery and represent a useful tool both for re-exploration and treatment, in expert and skilled hands.

BACKGROUND: The laparoscopic approach is a very popular technique for many gastrointestinal operations and barbed sutures may improve the difficulties of intracorporeal anastomosis by eliminating the need for knot tying. The aim of this systematic review with a meta-analysis is to explore literature to establish the security profile of barbed suture compared with conventional laparoscopic sutures. MATERIALS AND METHODS: A systematic search was performed in all electronic databases (PubMed, Web of Science, Scopus, EMBASE) and 12 studies were included in the analysis, involving 27,133 patients, whereof 3372 cases (patients undergone barbed suture usage) and 23,761 controls (patients undergone conventional suture usage). We found 3 studies discussing differences between barbed and conventional sutures in colorectal surgery and 8 studies presenting results in bariatric surgery, both in Roux-en-y gastric bypass and Mini Gastric/One Anastomosis Gastric Bypass. RESULTS: We found comparable rate of leaks, bleedings and stenosis. The meta-regression analysis demonstrated that, both in case of bariatric and colorectal surgery, the demographic characteristic of patients and the oncological features of neoplasms did not impact of these findings. As expected, operative time is significantly shorter when barbed suture is used. CONCLUSION: Our analysis on current literature define an acceptable security profile for barbed suture with effective results particularly in terms of shorter operative time.

BACKGROUND: Although it is known that portomesenteric venous thrombosis (PMVT) is associated with total colectomy and proctocolectomy in young patients with inflammatory bowel disease, little is known about incidence and risk factors of PMVT among the elderly population undergoing colorectal surgery for cancer. METHODS: Data of elderly patients (> 70 years) undergoing surgery for colorectal cancer were retrospectively registered. The occurrence of PMVT was correlated with the patients' characteristics and operative variables. Data collected included age, sex, obesity, ASA score, tumor degree, type of surgical resection, surgical approach (laparoscopic or open), and duration of surgery (from skin incision to the application of dressings). RESULTS: A total of 137 patients > 70 years who underwent surgery for colorectal cancer and developed an acute intraabdominal process with suggestive symptoms, needing a CT scan, were included. Three of these patients (2.1%) had portomesenteric venous thrombosis during the study period, which was proved with CT scan. There were no significant patients' characteristics or operative variables between patients with or without the occurrence of PMVT after surgery. Of interest, only operative time was significantly higher in patients with PMVT after surgery (256 ± 40 vs 140 ± 41, p < 0.001). CONCLUSIONS: PMVT as a cause of abdominal pain after colorectal surgery for cancer in the elderly population is uncommon. An index of suspicion for PMVT in an elderly postoperative colorectal cancer patient with sudden onset of abdominal pain must be maintained.

Although minimally invasive surgery is recognized as the gold standard of many surgical procedures, laparoscopic suturing is still considered as the most difficult skill in laparoscopic surgery. The introduction of barbed sutures facilitates laparoscopic suturing because it is not necessary to tie a knot. The efficacy of this method has been evaluated in different types of surgery; however, less is known about general surgery. We retrospectively analysed data from 378 patients who had undergone bariatric or surgical treatment for colic or gastric malignancy requiring a closure of gastroentero, entero-entero or enterocolotomy from January 2014 to January 2019, admitted to the General Surgery Unit and Operative Unit of Surgical Endoscopy of the University Federico II (Naples, Italy). We registered 12 anastomotic leaks (3.1%), 16 anastomotic intraluminal bleedings (4.2%) and 7 extraluminal bleedings. Other complications included 23 cases of postoperative nausea and vomit (6%), 14 cases of postoperative ileus (3.7%) and 3 cases of intra-abdominal abscess (0.8%). Overall complications rate was 19.8% (75/378). No postoperative death was registered. Thus, by pooling together 378 patients, we can assess that barbed suture could be considered safe and effective for closure of holes used for the introduction of a branch of mechanical stapler to perform intracorporeal anastomosis.
RESUMO
The management of chronic pilonidal disease remains controversial, but recently, new minimal invasive approaches have been proposed. Whereas in the conventional surgical treatment an elliptical wedge of skin and subcutaneous tissue is created to remove the sinus and its lateral tracks, the basis for our new treatment is to create a minimal elliptical wedge of the subcutaneous tissue, including all the inflamed tissue and debris while leaving the overlying skin intact. The mechanism of an endoscopic approach relies on use of the endoscope without cutaneous tissue damage. Advantages include shorter operative time and time to discharge, which impact resource management in both primary and secondary care: patients undergoing endoscopic technique have a high satisfaction rate, probably due to the low level of postoperative pain and early return to work and daily activities. However, it is mandatory that further studies would analyze surgical approaches to pilonidal sinus disease (PSD) with a consistent and adequate follow-up of at least 5 years. Both sinusectomy and endoscopic approach to PSD were found to be safe and effective compared with conventional techniques. Publishedresults of studies of newer approaches have demonstrated a low short-term complication rate, comparable to conventional surgery results.
RESUMO
Since its first description in 1883, different treatments for pilonidal sinus disease have been proposed, but we are still far from the identification of an ideal approach. The objective of this study is to determine if video-assisted ablation of pilonidal sinus (VAAPS) could be considered superior/non-inferior to standard sinusectomy for treatment of pilonidal sinus disease. After applying propensity score analysis, data from 40 patients who underwent sinusectomy and 40 patients who underwent VAAPS, from March 2011 to August 2013, were collected. The two groups were similar in terms of sex, age, BMI, smoking status and complexity of sinus. The mean operative time was less for the sinusectomy group compared with the minimally invasive treatment group (30.38 ± 6.23 vs 44.39 ± 7.76; p = 0.001). On the other hand, the recurrence rate (7.5% vs 25%; p = 0.035) was significantly lower in the VAAPS group and the infection rate showed a trend toward reduction in the endoscopically treated patients (12.5% vs 30%; p = 0.057). No differences were found in terms of pain score at 1 week from surgery (3.71 ± 1.24 vs 3.76 ± 1.39; p = 0.883), satisfaction at 6 months (8.3 ± 1.2 vs 8.2 ± 1.3; p = 0.78) and time off work (2.01 ± 1.30 vs 2.08 ± 1.24; p = 0.620). The effectiveness of our new technique can be assessed again and the comparative analysis with the conventional sinusectomy shows the feasibility of VAAPS, suggesting that this procedure is the best way to perform a sinusectomy.

BACKGROUND: Recently, it has been questioned if minimally invasive surgery for rectal cancer was surgically successful. We decided to perform a meta-analysis to determine if minimally invasive surgery is adequate to obtain a complete resection for curable rectal cancer. METHODS: A systematic search pertaining to evaluation between laparoscopic and open rectal resection for rectal cancer was performed until 30th November 2016 in the electronic databases (PubMed, Web of Science, Scopus, EMBASE), using the following search terms in all possible combinations: rectal cancer, laparoscopy, minimally invasive and open surgery. Outcomes analyzed were number of clear Distal Resection Margins (DRM or DM), complete Circumferential Resection Margins (CRM) and complete, nearly complete and incomplete Total Mesorectal Excision (TME) and of patients who received laparoscopic or open treatment for rectal cancer. RESULTS: 12 articles were included in the final analysis. The prevalence of successful surgical resection was similar between open and laparoscopic surgery. About distance from distal margin of the specimen, clear CRM and complete TME there were no statistically significant difference between the two groups (MD = -0.090 cm, p = 0.364, 95% CI -0.283, 0.104; OR = 1.032, p = 0.821, 95% CI 0.784, 1.360; OR = 0.933, p = 0.720, 95% CI 0.638, 1.364, respectively). The analysis of nearly complete TME showed a significant difference between the two groups (OR = 1.407, p = 0.006, 95% CI 1.103, 1.795), while the analysis of incomplete TME showed a non-significant difference (OR = 1.010, p = 0.964, 95% CI 0.664, 1.534). CONCLUSIONS: By pooling together data from 5 RCTs and 7 nRCTs, we are able to provide evidence of safety and efficacy of minimally invasive surgery. Waiting for further randomized clinical trials, our results are encouraging to introduce laparoscopic rectal resection in daily practice.

RESUMO
PURPOSE: Although intracorporeal anastomosis (IA) appears to guarantee a faster recovery compared to extracorporeal anastomosis (EA), the data are still unclear. Thus, we performed a systematic review of the literature with meta-analysis to evaluate the recovery benefits of intracorporeal anastomosis. MATERIALS AND METHODS: A systematic search was performed in electronic databases (PubMed, Web of Science, Scopus, EMBASE) using the following search terms in all possible combinations: "laparoscopic," "right hemicolectomy," "right colectomy," "intracorporeal," "extracorporeal," and "anastomosis." According to the pre-specified protocol, all studies evaluating the impact of choice of intra- or extracorporeal anastomosis after right hemicolectomy on time to first flatus and stools, hospital stay, and postoperative complications according to Clavien-Dindo classification were included. RESULTS: Sixteen articles were included in the final analysis, including 1862 patients who had undergone right hemicolectomy: 950 cases (IA) and 912 controls (EA). Patients who underwent IA reported a significantly shorter time to first flatus (MD = - 0.445, p = 0.013, Z = - 2.494, 95% CI - 0.795, 0.095), to first stools (MD = - 0.684, p < 0.001, Z = - 4.597, 95% CI - 0.976, 0.392), and a shorter hospital stay (MD = - 0.782, p < 0.001, Z = -3.867, 95% CI - 1.178, - 0.385) than those who underwent EA. No statistically significant differences in complications between the IA and EA patients were observed in the Clavien-Dindo I-II group (RD = - 0.014, p = 0.797, Z = - 0.257, 95% CI - 0.117, 0.090, number needed to treat (NNT) 74) or in the Clavien-Dindo IV-V (RD = - 0.005, p = 0.361, Z = - 0.933, 95% CI - 0.017, 0.006, NNT 184). The IA procedure led to fewer complications in the Clavien-Dindo III group (RD = - 0.041, p = 0.006, Z = - 2.731, 95% CI - 0.070, 0.012, NNT 24). CONCLUSIONS: Although intracorporeal anastomosis appears to be safe in terms of postoperative complications and is potentially more effective in terms of recovery after surgery, further ad hoc randomized clinical trials are needed, given the heterogeneity of the data available in the current literature.

AIM: To evaluate the impact of open or laparoscopic rectal surgery on pulmonary complications in elderly (>75 years old) patients. METHODS: Data from consecutive patients who underwent elective laparoscopic or open rectal surgery for cancer were collected prospectively from 3 institutions. Pulmonary complications were defined according to the ACS/NSQUIP definition. RESULTS: A total of 477 patients (laparoscopic group: 242, open group: 235) were included in the analysis. Postoperative pulmonary complications were significantly more common after open surgery (8 out of 242 patients (3.3%) versus 23 out of 235 patients (9.8%); p = 0.005). In addition, PPC occurrence was associated with the increasing of postoperative pain (5.04 ± 1.62 versus 5.03 ± 1.58; p = 0.001) and the increasing of operative time (270.06 ± 51.49 versus 237.37 ± 65.97; p = 0.001). CONCLUSION: Our results are encouraging to consider laparoscopic surgery a safety and effective way to treat rectal cancer in elderly patients, highlighting that laparoscopic surgery reduces the occurrence of postoperative pulmonary complications.
RESUMO
Leaks arising at the level of gastro-esophageal junction remain a major complication in patients who undergo a laparoscopic sleeve gastrectomy. Besides technical pitfalls, these fistulas are mainly attributable to tissue ischemia following the preparation of the gastric sleeve, explained by the irregular vascularization often present in the area of the gastro-esophageal junction. This video presentation shows how, the utilization of a new model of bougie can be of help in preventing a leak, allowing a better visualization of the particular vascular anatomy present at the level of the gastro-esophageal junction area. Currently, 25/334 (18 F-7 M) (7.4%) patients, who underwent a laparoscopic sleeve gastrectomy at our institution, were operated on using this new model of bougie. No leaks have been so far reported.

BACKGROUND: Little is known about the impact of bariatric surgery on obese infertile women seeking an assisted reproductive technology. METHODS: All obese women with a history of assisted reproductive technology (ART) failure that underwent ART treatment cycles both prior to and following bariatric surgery were included. ART outcomes were compared evaluating the duration and dose of gonadotrophins used; the measurement of day 3 FSH; the anti-mullerian hormone dosage; the number of follicles >15 mm; the number of retrieved and fertilized oocytes; the number of metaphase II, metaphase I and germinal vesicle oocytes; the number of embryos obtained; the number of top-quality oocytes and embryos; the number of transferred embryo; the pregnancy rate and the live birth rate. RESULTS: Forty women were included. The total number of gonadotropin units required and in the length of stimulation following bariatric surgery decreased (p = .001), with an increase of the number of follicles ≥15 mm (p = .005), of retrieved oocytes (p = .004), of top-quality oocytes (p = .001) and metaphase II oocytes (p = .008). More oocytes were fertilized (4.2 ± 1.7 vs 5.3 ± 2.4; p = .02). After surgery, we have registered also a better number of top-quality embryos (0.5 ± 0.6 vs 1.1 ± 0.9; p = .003). Pregnancy rate following the bariatric surgery increased to 15/40 (37.5%) (p < .001), and live birth rate (LBR) increased to 14/40 (35%) in the post-surgery group (p<. 001). CONCLUSIONS: Although additional research would be useful to draw definitive conclusion, our results appear to be encouraging enough to suggest the use of bariatric surgery in obese infertile women seeking an ART treatment.

BACKGROUND: We have designed a modified caudal-to-cranial approach to perform laparoscopic left colectomy preserving the inferior mesenteric artery for benign colorectal diseases. METHODS: IRB approval and informed consent have been obtained. A dissection is conducted to separate the descending mesocolon of the Gerota's plan from the medial aspect to the peritoneal lining to the left parietal gutter. The peritoneal layer is incised parallel to the vessel and close to the colonic wall. The dissection is continued anteriorly up to reach the resected parietal gutter. A passage into the mesentery of the upper rectum is created for the allocation of the stapler and the dissection of the rectum. These maneuvers permit to straighten the mesentery simplifying the identification and cutting of the sigmoid arteries. A caudal-to-cranial dissection of the mesentery is performed from the sectioned rectum to the proximal descending colon by a sealed envelope device. It can be very useful to mobilize the colon in any direction: laterally, medially, or upward. The dissection is performed along the course of the vessel up to the proximal colon, with progressive sectioning of the sigmoid arterial branches. The specimen is extracted by a pfannenstiel incision. The anastomosis is performed transanally with a circular stapler according to Knight-Griffin technique. RESULTS: We performed a laparoscopic segmental colectomy using this approach for 21 patients with benign sigmoid lesions: 13 diverticulitis, 3 flat polypoid lesions (no lift-up sign), and 5 bowel endometriosis. The mean operative time and blood loss were 161.4 ± 15.7 min and 50 ± 40 ml, respectively. There were not a single conversion to open surgery and no any leakage or stricture. Only 2 cases of intraluminal bleeding and 1 case of wound infection (treated conservatively) were observed. CONCLUSION: We consider this approach to be safe and useful for segmental colectomy to be performed sectioning the sigmoid artery close to the colonic wall.

IMPORTANCE: Video-assisted ablation of pilonidal sinus (VAAPS) is a new minimally invasive treatment based on the complete removal of the sinus cavity with a minimal surgical wound. OBJECTIVE: To validate the safety and efficacy of VAAPS. DESIGN, SETTING, AND PARTICIPANTS: From January 1, 2012, through December 31, 2013, we enrolled 145 consecutive patients from an intention-to-treat population at a single academic center in Italy. The last date of follow-up for this analysis was December 31, 2014. Patients with chronic nonrecurrent pilonidal sinus were randomized to minimally invasive (76 patients) or conventional (69 patients) treatment of pilonidal sinus. INTERVENTIONS: VAAPS and Bascom cleft lift procedure. MAIN OUTCOMES AND MEASURES: The primary end point of the study was time off work. Secondary end points were the rates of operative success and perioperative complications (infection and recurrence), operative time, patient satisfaction, and intraoperative and postoperative pain ratings. RESULTS: Of the 145 patients, 60 (78.9%) were male and 16 (21.1%) were female in the minimally invasive treatment group, and 54 (78.3%) were male and 15 (21.7%) were female in the conventional treatment group. The mean (SD) age of the patients was 25.5 (5.9) years in the minimally invasive treatment group and 25.7 (5.3) in the conventional treatment group. In the minimally invasive treatment group, mean (SD) time off work was significantly less compared with the conventional treatment group (1.6 [1.7] vs 8.2 [3.9] days; P < .001). Mean (SD) operative time was significantly longer in the minimally invasive treatment group (42.9 [9.8] minutes) vs the conventional treatment group (26.5 [8.7] minutes), P < .001. Although the overall complication rate was similar in both groups, there were fewer infections (1 [1.3%] vs 5 [7.2%]; P = .10) recorded in the minimally invasive treatment group. Similarly, patients enrolled in the minimally invasive treatment group expressed significantly less pain and higher satisfaction. CONCLUSIONS AND RELEVANCE: In the new era of minimally invasive treatment surgery, pilonidal sinus could become a disease treated with an endoscopic approach. Although additional studies are needed to provide a definitive conclusion, our results encourage considering the adoption of this treatment as the most effective way to treat pilonidal sinus.

Colorectal cancer (CRC) is one of the most frequent and deadly malignancies worldwide. Despite the progresses made in diagnosis and treatment, the identification of tumor markers is still a strong clinical need, because current treatments are efficacious only in a subgroup of patients. UbcH10 represents a potential candidate biomarker, whose expression levels could be employed to predict response or resistance to chemotherapy or targeted agents. UbcH10 mRNA and protein expression levels have been evaluated in a large group of CRC patients and correlated with clinico-pathological characteristics, including KRAS mutations. Moreover, the endogenous levels of UbcH10 and its role on cell growth have been evaluated in CRC cells. Finally, to investigate the impact of UbcH10 protein expression on the response to irinotecan, its active metabolite SN-38 and cetuximab treatment, UbcH10 silencing experiments were carried-out on two colon carcinoma cell lines, Caco-2, and DLD1. Overexpression of UbcH10 mRNA and protein was observed in the vast majority of patients analyzed. UbcH10 suppression decreased CRC cell growth rate (at least in part through deregulation of Cyclin B and ERK1) and sensitized them to pharmacological treatments with irinotecan, SN-38 and cetuximab (at least in part through a down-regulation of AKT). Taken together, these findings indicate that UbcH10 expression regulates CRC growth and could play an important role in the personalization of the therapy of CRC patients.

Pilonidal sinus surgery could, as of now, be considered a surgery tailored more to the surgeon than to the patient. In an attempt to give to surgeons an objective instrument of decision, we have evaluated which variables could be considered predictive of postoperative complications after pilonidal sinus surgery. A prospective electronic database of all patients treated for sacrococcygeal pilonidal disease was analysed. Sex, age, obesity, smoking, recurrent disease, the presence of multiple orifices and the distance between the most lateral orifice and midline were recorded and correlated with the occurrence of postoperative complications (infection and recurrence); 1006 patients were evaluated. Excision with primary mid-line closure was performed on all the patients. Mean follow-up was 7·3 ± 3·6 years. A total of 158 patients with postoperative complications (infection and/or recurrence) were recorded during this period. A multivariate analysis showed that, after adjusting for major clinical and demographic characteristics, only a recurrent disease [odds ratio (OR): 3·41, 95% confidence interval (CI): 1·89-6·15, P < 0·001] and the distance of lateral orifice from midline (OR: 26·3, 95% CI: 12·2-56·7, P < 0·001) were independent predictors of overall postoperative complications. Focussing on the distance from midline, the receiver operative characteristic (ROC) analysis showed that the distance of lateral orifice from midline predicted 79·2% of complications and the Youden's test identified the best cut-off as 2·0 cm for this variable. An evidence-based tool for deciding on the type of surgical intervention could be developed and validated by further ad hoc prospective studies evaluating our results in comparison to other different types of surgical techniques. Our results support the use of these variables as an effective way to tailor pilonidal sinus surgery to the patient, so as to obtain the best results in patient care.

BACKGROUND: To identify the correlation between high body mass index (BMI ≥ 25) and the risk of postoperative complications of thyroidectomy. METHODS: A comparative study between thyroidectomy performed in normal or overweigh-obese patients has been performed. Postoperative outcomes, including hypocalcemia, laryngeal nerve palsy, bleeding, operation time and hospital stay, were evaluated. RESULTS: A total of 266 patients underwent total thyroidectomy were included. Of them, 104 patients had a BMI below 25 and 162 patients had a BMI ≥ 25. There was no statistically significant difference in the occurrence of early or permanent hypoparathyroidism, recurrent laryngeal nerve palsy, bleeding complications, or postoperative duration of hospital stay. There was, however, a higher operative time in patients with a BMI ≥ 25. CONCLUSION: Despite the longer operative time, thyroidectomy can be performed safely in patients with a BMI ≥ 25.

Little is known about the impact of weight loss interventions on pregnancy rate. A systematic review with meta-analysis of literature has been performed to evaluate the incidence of successful pregnancy after bariatric interventions in infertile women. By pooling together data from 589 infertile obese women, we have been able to provide an aggregate estimation of successful pregnancy after weight loss interventions. Our results showed an impressive high incidence (58%) of infertile women who become spontaneously pregnant after surgery. Based on our results, bariatric interventions could be included in the treatment of obesity-related infertility. However, the results must be interpreted with caution owning to the quality of the data provided by included studies. Further ad hoc studies are needed to validate the effectiveness of bariatric interventions on reproductive function.
