Background: 3D laparoscopy has been proposed with the aim of improving the depth perception and overall operative performance. To aim of this study is to compare 3D laparoscopy with conventional 2D laparoscopy in terms of operative time and visual parameters., Methods: This is a prospective, randomized, single-center trial designed to determine 10% reduction in the mean operative time. Ulcerative colitis patients >18 years of age who underwent laparoscopic total abdominal colectomy with end ileostomy between 2015 and 2020 were included. Patients were randomized into 3D and 2D laparoscopy groups. Duration of operation and surgeons' evaluation of the visualization system were the primary outcomes., Results: Fifty-three subjects (26 in 2D, 27 in 3D group) were included in the analysis, with 56% being male. Mean age and body mass index were 40 (16.3) years and 23.5 (4.7) kg/m 2 , respectively. Twenty-five subjects underwent single port laparoscopic surgery, of whom 13 were in 3D and 12 in 2D group. Mean operative time was 75.3 (30.8) versus 82.7 (38.6) minutes (P = 0.4) for 3D and 2D groups, respectively. Operative times spent for individual steps were comparable. Post-operative minor complications (8 in 3D versus 8 in 2D, P = 1) and median number of times for scope maintenance were also similar between the groups. 69% of the visual evaluation survey results favoured 3D over 2D (P = 0.014)., Conclusion: Three-dimensional laparoscopy for total colectomy in ulcerative colitis patients is safe and feasible option providing better visualization with no difference in operative time., (© 2023 The Authors.

Aim: Failure ratio of an anti-reflux surgery is 2-17% in adults. After unsuccessful fundoplications, if necessary, revisional surgeries can be performed. Revisional surgeries are technically difficult to perform and require professionally advanced experience. On the other hand, it is still controversial which technique should be used in revisional surgery. The aim of this study is to present our experience with revisional surgical procedures for complications or recurrences after anti-reflux surgeries., Material and Metods: A total of 18 patients, 16 of whom were referred to our clinic from other centers, and who underwent revisional surgery for failed fundoplication between 2014 and 2019 were retrospectively analyzed RESULTS: Five patients were male and 13 were female. The mean age was 40.3±11.7 years. The most common symptom was the persistence of reflux symptoms (61.2%). Indications for revisional surgery were recurrent hiatal hernia in 10 patients, thightness in 4 patients, mesh migration in 2 patients, mesh migration with recurrent hiatal hernia in 1 patient, and mesh migration with thightness in 1 patient. The mean operative time was 107.2+29.2 minutes. The median hospital stay was 2.9 days (range: 1-6 days). The most common surgical procedure performed was the repair of hiatal crura with mesh, and reconstruction of fundoplication and fixation of neo-fundoplication to the right crus (44.4%). In addition, other surgical procedures performed were takedown of the previous fundoplication (16.6%), takedown of the previous fundoplication and reconstruction of fundoplication (11.1%), cruroplasty and fundoplication with gastric wedge resection (11.1%), removal of the mesh and takedown of the previous fundoplication (5.6%), removal of sutures from the hiatal crura (5.6%), and gastric wedge resection (5.6%). Four patients (27.8%) developed morbidity due to gastric perforation and pleural opening during these procedures. The median follow-up period was 29 months (range: 6-69 months). Two cases (11.1%) who underwent revisional surgery failed, and re-revisional surgery was performed., Conclusions: Revisionary surgical procedures performed for failed anti-reflux surgery are not limited to re-fundoplication. Different procedures such as takedown of the previous fundoplication, reconstruction of fundoplication, removal of the mesh, removal of the sutures or wedge resection may be necessary. These procedures can successfully be performed laparoscopically by experienced surgeons in well-equipped centers., Key Words: Fundoplication, Gastroesophageal reflux, Laparoscopy, Revisional Surgery, Antireflux surgery.

Scopo Dello Studio: L'emicolectomia destra per escissione mesocolica completa (EMC) laparoscopica mostrerebbe benefici comparabili a breve termine, nonché esiti patologici e oncologici per la chirurgia a cielo aperto. Lo scopo di questo studio era di confrontare la tecnica laparoscopica e la EMC aperta per i tumori del colon sul lato destro in termini di campioni patologici e risultati a breve termine., Materiale E Metodi: I dati dei pazienti sottoposti a EMC laparoscopica (n=31) e EMC aperto (n=35) per adenocarcinoma del colon destro tra gennaio 2016 e giugno 2019 sono stati analizzati retrospettivamente. Sono stati confrontati dati demografici, parametri preoperatori, peroperatori e postoperatori e campioni di patologia dei due gruppi., Risultati: Non ci sono state differenze statistiche tra il gruppo laparoscopico di EMC e il gruppo aperto di EMC in termini di età, sesso, indice di massa corporea, posizione del tumore, punteggio dell'American Society of Anesthesiologists (ASA), presenza di comorbidità, storia di altre neoplasie e precedente chirurgia addominale (p>0,05). I pazienti nel gruppo EMC laparoscopico presentavano lunghezze d'incisione più brevi, tempi operativi più lunghi, minore perdita di sangue operativa, tempi di mobilizzazione più brevi, recupero precoce del movimento intestinale, tempo più breve per dieta leggera, durata ridotta della degenza e dimensioni del tumore più piccole (p<0,05). Il numero medio di linfonodi raccolti in gruppi laparoscopici e di EMC aperti non era statisticamente significativo (29,83+8,90 e 31,34+13,10, rispettivamente). Non ci sono state differenze statistiche in termini di lunghezza del campione tra i gruppi laparoscopici e aperti di EMC (35,19+9,8 cm e 32,71+11,12 cm, rispettivamente). Il tasso di complicanze postoperatorie di 30 giorni era più elevato nel gruppo EMC aperto (35,5% contro 42,9%, rispettivamente), ma non statisticamente significativo (p>0,05)., Conclusioni: Patologici (lunghezze dei campioni, lunghezze dei margini di resezione, numero di linfonodi e resezione R0) e risultati a breve termine del gruppo laparoscopico di EMC erano comparabili. Inoltre, la EMC laparoscopica ha conferito benefici a breve termine in termini di lunghezze di incisione più brevi, minore perdita di sangue operativa, riduzione dei tempi di mobilizzazione, recupero precoce dei movimenti intestinali, minor tempo di dieta leggera e riduzione della durata della degenza ospedaliera. Sulla base di questi risultati, la EMC laparoscopica può essere considerata come un approccio elettivo di routine per il carcinoma del colon destro.

Aim: Achalasia is a well-known disease among esophageal motility disorders, and all treatments for this disease are aimed at relaxing the lower esophageal sphincter (LES). Recently, endoscopic and surgical myotomy techniques are used more frequently because they give better results than other conservative techniques. In this study, we aimed to present the early results of surgical myotomy and anterior fundoplication techniques in the treatment of achalasia-related dysphagia., Methods: Our study enrolled patients who operated with laparoscopic myotomy and anterior fundoplication for achalasia between 2014 and 2019. Patients' demographic and clinical properties, operative details, and postoperative shortterm outcomes were retrospectively analyzed., Results: A total of 25 patients (11 women, 14 men) were enrolled. The mean age was 40.72±13.6 (range 18-66) years. The mean LES pressure was 26.6±11.2 (range 16-50) mmHg. The mean esophageal myotomy length was 7.83±1.88 (range 7-12 cm). Esophagus perforation developed in one patient during myotomy. The mean time to start oral feeding was 2.56±0.76 (range 2-4) days, and the mean length of hospital stay was 4.96±1.17 (range 3-8) days. During the follow-up, symptom regression was observed in 92 % of patients at the end of a 1-year., Conclusion: According to our results and available literature, myotomy with Dor fundoplication is an effective technique that can be used to treat achalasia disease., Key Words: Achalasia, Dor fundoplication, Heller myotomy.

Aim: The aim of this study is to compare the oncologic efficacy of laparoscopic total gastrectomy (LTG) versus open total gastrectomy (OTG) for gastric cancer and to provide our experiences regarding this surgery., Methods: A total of 107 patients who underwent curative total gastrectomy for gastric adenocarcinoma between September 2015 and September 2018 were included in this study. Demographic characteristics, operative parameters, histopathological results, postoperative morbidity and mortality results of the patients were evaluated., Results: Of 107 patients, 70 were men and 37 women. OTG consisted of 89 patients and LTG consisted of 18 patients. The mean age in OTG was 59.4 years, the mean age in LTG was 57.3 years. The mean number of lymph nodes harvested was 30.5 14.6 in OTG and 33.0 10.1 in LTG. The number of metastatic lymph nodes harvested was 7.4 10.5 in OTG and 10.0 11.8 in LTG (p= 0.366), and there was no statistical difference between the two groups. The time of onset of oral intake, anastomotic leakage, and postoperative mortality was similar in both groups. Operative duration and length of hospital stay were significantly higher in LTG. Postoperative survival duration was similar in both procedures CONCLUSION: Laparoscopic total gastrectomy for gastric cancer is an oncologically safe procedure but had a longer operation time and a longer hospital stay. There was no significant difference number of harvested lymph nodes, number of metastatic lymph nodes, and tumor localization between the two groups KEY WORDS: Gastric cancer, Laparoscopy, Gastrectomy.

Purpose: Whether the reported theoretical benefits of single-port laparoscopic (SPL) approach can be converted to superior clinical outcomes is still unknown for ulcerative colitis (UC) patients undergoing second-stage proctectomy. This study aimed to compare the short-term postoperative and long-term pouch-related functional outcomes of SPL, multiport laparoscopic (MPL), and direct view (DV) completion proctectomy with ileal-pouch anal anastomosis (CP/IPAA)., Materials and Methods: Patients who underwent either SPL, MPL, or under DV CP/IPAA for UC between August 2009 and August 2014 were identified from an institutional review board-approved, prospectively maintained institutional database and reviewed. Demographics, patient characteristics, short-term and long-term complications, and morbidity were compared between the 3 groups. Multivariate logistic or Cox regression analysis was conducted for covariate adjustments., Results: Groups (SPL: n=36; MPL: n=67; DV: n=97) were comparable in terms of preoperative characteristics and demographics except for age. The SPL group was associated with reduced estimated blood loss, reduced length of stay compared with the MPL and DV groups, and shorter operating time compared with the MPL group (P<0.001). Similar short-term postoperative and long-term pouch-related functional outcomes were noted without significant differences in quality of life scores among the 3 groups., Conclusions: SPL CP/IPAA for UC can be safely performed with superior short-term outcomes such as reduced intraoperative blood loss and length of hospital stay compared with MPL and under direct view approaches, and shorter operating time compared with MPL.

Background: Previous work from our institution has characterized the learning curve for open ileal pouch-anal anastomosis (IPAA). The purpose of the present study was to assess the learning curve of minimally invasive IPAA., Methods: Perioperative outcomes of 372 minimally invasive IPAA by 20 surgeons (10 high-volume vs. 10 low-volume surgeons) during 2002-2013, included in a prospectively maintained database, were assessed. Predicted outcome models were constructed using perioperative variables selected by stepwise logistic regression, using Akaike's information criterion. Cumulative sums (CUSUM) of differences between observed and predicted outcomes were graphed over time to identify possible improvement patterns., Results: Institutional pelvic sepsis and other pouch morbidity rates (hemorrhage, anastomotic separation, pouch failure, fistula) significantly decreased (18.2 vs. 7.0 %, CUSUM peak after 143 cases, p = 0.001; 18.4 vs. 5.3 %, CUSUM peak after 239 cases, respectively, p < 0.001). Institutional total proctocolectomy mean operative times significantly decreased (307 min vs. 253 min, CUSUM peak after 84 cases, p < 0.001), unlike completion proctectomy (p = 0.093) or conversion rates (10 vs. 5.4 %, p = 0.235). Similar learning curves were identified among high-volume surgeons but not among low-volume surgeons. Learning curves were identified in the two busiest individual surgeons for pelvic sepsis (peaks at 47 and 9 cases, p = 0.045 and p = 0.002) and in one surgeon for operative times (CUSUM peak after 16 and 13 cases for both total proctocolectomy and completion proctectomy (p < 0.001 and p = 0.006) but not for other pouch complications (peak at 49 and 41 cases, p = 0.199 and p = 0.094)., Conclusion: Pouch complications, particularly pelvic sepsis, are the most consistent and relevant learning curve end points in laparoscopic IPAA.

The present study reports an early institutional experience with robotic proctectomy (RP) and outcome comparison with laparoscopic proctectomy (LP) in patients with inflammatory bowel disease (IBD). Patients who underwent either RP or LP during proctocolectomy for IBD between January 2010 and June 2014 were matched (1:1) and reviewed. Twenty-one patients undergoing RP fulfilled the study criteria and were matched with an equal number of patients who had LP. Operative time was longer (304 vs. 213 min, P=0.008) and estimated blood loss was higher in the RP group (360 vs. 188 mL, P=0.002). Conversion rates (9.5% vs. 14.3%, P>0.99), time to first bowel movement(2.29±1.53 vs. 2.79±2.26, P=0.620), and hospital length stay(7.85±6.41 vs. 9.19±7.47 d, P=0.390) were similar in both groups. No difference was noted in postoperative complications, ileal pouch to anal canal anastomosis-related outcomes, Cleveland Global Quality of Life, and Short Form-12 health survey outcomes between RP and LP. Our good results with standard laparoscopy are unlikely to be improved with robotics in proctectomy cases. Potential benefits of robotic approach for completion proctectomy warrant further investigation as experience grows with robotics.

Aim: Colectomies performed according to complete mesocolic excision (CME) principles have demonstrated an improvement in the quality of surgical specimen and a potential improvement of long-term results. The procedure is technically challenging and has a risk of serious complications, especially when performed laparoscopically. We here aimed to analyze our short-term results in relation to laparoscopic CME right hemicolectomy carried out for right-sided colon cancers. Material and Methods: Demographic data and preoperative, perioperative and postoperative parameters of twenty-three patients who underwent laparoscopic CME between January 2017 and January 2019 in our clinic for right-sided colon adenocarcinoma were retrospectively analysed. Results: There were 23 patients in our study and the mean (SD) age was 61.9±14.8. In the present series, 30% of patients were ≥70 years old, and three were ≥80 years old. Four patients were ASA class 3. Fifty-two percent of patients had comorbidities, and two had different system malignancies in their medical history. While the mean (SD) body mass index (BMI) was 25±4.3, BMI of 4 patients were over 30. Six of patients had a history of previous abdominal surgery. No perioperative mortality was observed. Thirteen percent of the patients developed wound site infection. Anastomotic leakage occurred in 2 cases, and one of them underwent reoperation. The mean (SD) operation time was 168±33 min. Good quality specimens were obtained with a mean (SD) length of 34.2±9.7 cm, a proximal margin of 14±8.2 cm and a distal margin of 16.6±8.9 cm. The mean (SD) number of harvested lymph nodes was 31.9±7.7. The radial surgical margin of all specimens was negative. The mean (SD) postoperative hospital stay was 7.2±2.8 days. Conclusion: We believe that our CME technique performed by laparoscopic method for right-sided colon cancers is safe and applicable, and allows obtaining good quality specimens when evaluating the short-term results. However, there is still a need for randomized controlled trials to evaluate the contribution to survival. [ABSTRACT FROM AUTHOR]
