Combined endoscopic-laparoscopic resection of colon polyps.

Aims: To analyze the current literature on combined endoscopic-laparoscopic resection of colon polyps and to compare this new approach to standard laparoscopic colonic resection for polyps not suitable for endoscopic resection. Results: Several studies demonstrated that with a combined endoscopic-laparoscopic approach, polyps were successfully resected in 82-91% with a low morbidity of 3-10% and a short hospital stay of 1-2 days. Segmental laparoscopic resection was necessary in only 9-12%, but had a conversion rate to open surgery of 15% with an average hospital stay of 6-11 days. A cancerous polyp was found in 6-13% after a combined approach, with lymph node metastasis in 6%. Recurrent polyps after a combined endoscopic-laparoscopic resection seem to be rare, but follow-up of most studies is short and incomplete. Conclusion: Combined endoscopic-laparoscopic resection of colon polyps is feasible, safe, and has a high success rate. Malignant lesions can be treated laparoscopically during the same operation, avoiding the need for a second procedure, and with good long-term oncologic outcome.

Transrectal specimen extraction after laparoscopic left colectomy: a case-matched study.

Aim  Avoiding 'mini-laparotomy' to extract a colectomy specimen may decrease wound complications and further improve recovery after laparoscopic surgery. The aim of this study was to develop a new technique for transrectal specimen extraction (TRSE) and to compare it with conventional laparoscopy (CL) for left sided colectomy. Method  Eleven patients with benign disease requiring either sigmoid or left colon resection underwent TRSE. The unfired circular stapler was inserted transanally and used as a guide to suture-close the recto-sigmoid junction laparoscopically and as a handle to pull the sutured sigmoid through the opened rectum inside a laparoscopic camera bag. The anvil was inserted into the lumen of the intussuscepted sigmoid and pushed to the level of the anastomosis. The anastomosis was fashioned end-to-end in the first patients and side-to-end in the following patients to improve safety. Intra-operative and postoperative outcomes of patients undergoing TRSE were compared with those of a group of 20 patients undergoing CL, who were matched for type of resection, body mass index and age. Results  The procedure was successful in all but the first patient who was converted to conventional laparoscopic colectomy without any additional morbidity. Two patients in the end-to-end anastomosis group, but none in the side-to-end group, developed peri-anastomotic sepsis. Compared with CL, patients undergoing TRSE did not show any significant differences in operative time, recovery or morbidity. Conclusion  Transrectal specimen extraction after left colectomy using the circular stapler technique is feasible. A side-to-end anastomosis appears safer than an end-to-end anastomosis. Further studies are needed to explore the potential advantages of this procedure over CL.

The role of laparoscopic biopsies in lumbar spondylodiscitis.

Infection of an intervertebral disk is a serious condition. Diagnosis often is elusive and difficult. It is imperative to obtain appropriate microbiological specimens before initiation of treatment. The authors describe a 51-year-old woman with lumbar spondylodiscitis that was because of infection after the placement of an epidural catheter for postoperative analgesia. A spinal magnetic resonance imaging confirmed the diagnosis, but computed tomography-guided fine needle biopsy did not provide adequate material for a microbiologic diagnosis. Laparoscopic biopsies of the involved disk provided good specimens and a diagnosis of Propionibacterium acnes infection. The authors believe that this minimally invasive procedure should be performed when computed tomography-guided fine needle biopsy does not provide a microbiologic diagnosis in spondylodiscitis.

Transhiatal laparoscopic resection of intrathoracic esophageal duplication in a 6-month-old boy.

We report the case of a 6-month-old boy known antenatally to have a mediastinal cyst. Postnatal workup showed a noncommunicating compressive cyst bound to the lower third of the native esophagus. He underwent its removal by transhiatal laparoscopy. This appears to be the first case of laparoscopic removal of a thoracic esophageal duplication cyst in a child.

Randomized clinical trial on epidural versus patient-controlled analgesia for laparoscopic colorectal surgery within an enhanced recovery pathway.

OBJECTIVE: To compare epidural analgesia (EDA) to patient-controlled opioid-based analgesia (PCA) in patients undergoing laparoscopic colorectal surgery. BACKGROUND: EDA is mainstay of multimodal pain management within enhanced recovery pathways [enhanced recovery after surgery (ERAS)]. For laparoscopic colorectal resections, the benefit of epidurals remains debated. Some consider EDA as useful, whereas others perceive epidurals as unnecessary or even deleterious. METHODS: A total of 128 patients undergoing elective laparoscopic colorectal resections were enrolled in a randomized clinical trial comparing EDA versus PCA. Primary end point was medical recovery. Overall complications, hospital stay, perioperative vasopressor requirements, and postoperative pain scores were secondary outcome measures. Analysis was performed according to the intention-to-treat principle. RESULTS: Final analysis included 65 EDA patients and 57 PCA patients. Both groups were similar regarding baseline characteristics. Medical recovery required a median of 5 days (interquartile range [IQR], 3-7.5 days) in EDA patients and 4 days (IQR, 3-6 days) in the PCA group (P = 0.082). PCA patients had significantly less overall complications [19 (33%) vs 35 (54%); P = 0.029] but a similar hospital stay [5 days (IQR, 4-8 days) vs 7 days (IQR, 4.5-12 days); P = 0.434]. Significantly more EDA patients needed vasopressor treatment perioperatively (90% vs 74%, P = 0.018), the day of surgery (27% vs 4%, P < 0.001), and on postoperative day 1 (29% vs 4%, P < 0.001), whereas no difference in postoperative pain scores was noted. CONCLUSIONS: Epidurals seem to slow down recovery after laparoscopic colorectal resections without adding obvious benefits. EDA can therefore not be recommended as part of ERAS pathways in laparoscopic colorectal surgery.

Sagittal abdominal diameter is a better predictor than body mass index for duration of laparoscopic left colectomy.

BACKGROUND: Visceral obesity (VO) increases technical difficulty in laparoscopic surgery. The body mass index (BMI) does not always correlate to intra-abdominal fat distribution. Our hypothesis was that simple anthropometric measures that reflect VO, could predict technical difficulty in laparoscopic colorectal surgery, as reflected by the operative time, more accurately than the BMI. METHODS: Charts of all consecutive patients who underwent laparoscopic left colon resection in our institution between 2007 and 2010 were reviewed retrospectively. On a preoperative CT scan, anthropometric measures were taken on an axial plane at the L4-L5 level. Demographic, operative and anthropometric CT measures were correlated with the operative time. Logistic regression analysis was performed to assess the value of anthropometric CT measures or BMI to predict the duration of the colectomy. RESULTS: 121 patients with elective left colon resection for benign (56%) or malignant disease (44%) were included. There were 74 sigmoid resections (61%), 21 left hemicolectomies (17%) and 26 low anterior resections (22%). A longer sagittal abdominal diameter (≥24.8 cm) was significantly associated with longer corrected operative time (248 vs. 228 min, p = 0.043). In multivariate analysis, greater sagittal abdominal diameter, sagittal internal diameter and abdominal perimeter were significantly associated with longer operative time. No significant association was found for the BMI neither in univariate nor in multivariate analysis. CONCLUSIONS: This study suggests that simple linear measures taken on a CT scan, such as sagittal abdominal diameter, sagittal internal diameter and abdominal perimeter, may predict longer operative time in laparoscopic left colonic resections more accurately than BMI.

Place actuelle de la papillotomie chirurgicale transduodénale [Current status of surgical transduodenal papillotomy].

The treatment of biliary lithiasis has changed during the past 20 years. Cholecystectomy remains the gold standard for cholelithiasis, but many options are available for calculi of the common bile duct. Among them are surgical open or laparoscopic choledochotomy, biliary-enteric anastomosis, transduodenal sphincterotomy (TDS), endoscopic sphincterotomy. With the aim to describe the current place of TDS, we reviewed the patients operated on in our department between 1976 and 1992. We found 78 patients with a mean age of 58 years (26-89 years). 34 (43%) of them had acute cholecystitis, with 26 being operated on urgently. 47 (60%) were jaundiced, 15 (19%) had pancreatitis and 12 (15%) had cholangitis before operation. Indications for TDS have been impacted stone or absence of progression of the contrast medium on intraoperative cholangiography in 71 patients (91%). 3 patients died (1 pulmonary embolism, 1 sepsis of pulmonary origin, 1 MOF syndrome complicating preoperative necrotizing pancreatitis). 30 patients (38%) had complications, of which 20 were directly related to TDS. Hemorrhage occurred in 4 cases, and resolved spontaneously without transfusion. Hyperamylasemia occurred in 17 instances, but clinical pancreatitis developed in only 1 case, with complete resolution. 1 duodenal fistula healed after conservative therapy. No death is attributable directly to TDS. Today, the importance of endoscopic sphincterotomy is increasing. This retrospective study shows that TDS, if performed with caution, does not increase the operative risks even in emergent operations. During surgical exploration of the common bile duct, TDS is indicated to remove an impacted stone, or as a bilio-enteric anastomosis if multiple stones are present with a thin common duct.(ABSTRACT TRUNCATED AT 250 WORDS)

Impact of examinees' stereopsis and near visual acuity on laparoscopic virtual reality performance.

PURPOSE: Laparoscopic surgery represents specific challenges, such as the reduction of a three-dimensional anatomic environment to two dimensions. The aim of this study was to investigate the impact of the loss of the third dimension on laparoscopic virtual reality (VR) performance. METHODS: We compared a group of examinees with impaired stereopsis (group 1, n = 28) to a group with accurate stereopsis (group 2, n = 29). The primary outcome was the difference between the mean total score (MTS) of all tasks taken together and the performance in task 3 (eye-hand coordination), which was a priori considered to be the most dependent on intact stereopsis. RESULTS: The MTS and performance in task 3 tended to be slightly, but not significantly, better in group 2 than in group 1 [MTS: -0.12 (95 % CI -0.32, 0.08; p = 0.234); task 3: -0.09 (95 % CI -0.29, 0.11; p = 0.385)]. The difference of MTS between simulated impaired stereopsis between group 2 (by attaching an eye patch on the adominant eye in the 2nd run) and the first run of group 1 was not significant (MTS: p = 0.981; task 3: p = 0.527). CONCLUSION: We were unable to demonstrate an impact of impaired examinees' stereopsis on laparoscopic VR performance. Individuals with accurate stereopsis seem to be able to compensate for the loss of the third dimension in laparoscopic VR simulations.

Laparoscopic technique to perform a true Stamm gastrostomy in children.

PURPOSE: A surgical gastrostomy is mandatory in cases where a PEG is not feasible. Various minimally invasive techniques have been described, but many involve unusable materials in small children and/or have risk of disunion. We describe a technique for true Stamm gastrostomy performed by laparoscopy (LSG) with a purse string suture and four points of attachment onto the wall. METHOD: We reviewed 20 children who underwent an LSG from 2010 to 2013. After incision of the skin at the location planned for the gastrostomy, using three 3-5mm ports the stomach is fixed to the wall by three suspension stitches, which are entered and then emerged subcutaneously. A fourth stitch of attachment is used to make an award on the stomach and tie around the gastrostomy tube. RESULTS: Mean age was 4.2years, with 70% aged <2years. All children were malnourished, most often severely. All but two underwent a concomitant fundoplication. Feeding through the gastrostomy started on D0 or D1. Total feeding by gastrostomy was achieved in a mean duration of 2.9day. Mean hospital stay was 4.5days. There was no perioperative complication. Mean follow-up was 14months. Once, the balloon was accidently deflated and reinflated in the wall leading to its necrosis. Five peristomial granulomas were noticed. It was always possible to replace the tube by a gastrostomy device at least 6weeks after surgery. CONCLUSION: This new technique for true Stamm gastrostomy by laparoscopy reproduces exactly the one done by laparotomy, without special equipment. It can be made since the neonatal period, in all the circumstances when a laparoscopy is possible.

Complications After Laparoscopic Roux-en-Y Gastric Bypass in 1573 Consecutive Patients: Are There Predictors?

BACKGROUND: Roux-en-Y gastric bypass (RYGBP), one of the commonest performed bariatric procedures, remains a technically challenging operation associated with significant morbidity in high-risk patients. This study was conducted in order to identify predictors of complications after laparoscopic RYGBP. METHODS: Our prospectively established database has been assessed to review 30-day and in-hospital complications graded according to a validated scoring system (Clavien-Dindo) and separated into minor (Clavien-Dindo I-IIIa) and major (Clavien-Dindo IIIb-IV) complications. Patient- and procedure-related factors were analyzed using univariate analysis. Significant factors associated with morbidity were introduced into a multivariate analysis to identify independent predictors. RESULTS: Between 1999 and 2012, 1573 patients underwent laparoscopic RYGBP, 374 male and 1199 female. Mean age was 41 years, and mean body mass index (BMI) was 44.5 kg/m(2). One hundred fifty-nine procedures were reoperations. One hundred fifty (9.5 %) patients developed at least one complication, and 43 (2.7 %) had major complications, leading to death in one case (0.06 %). Risk factors for morbidity were male gender (p = 0.006) and overall experience of the team (p < 0.0001). Prolonged 3-day antibiotic therapy was associated with significantly reduced overall (p < 0.0001) and major (p = 0.005) complication rates. Major complications were associated with smoking (p = 0.016). CONCLUSIONS: The most significant individual risk factors for early complications after RYGBP are male gender, limited surgical experience, and single dose of antibiotics. RYGBP should be performed by experienced teams. Smoking should be discontinued before surgery. Prolonged antibiotic therapy could be considered, especially if a circular stapled gastrojejunostomy is performed with the anvil introduced transorally.

Laparoscopic Roux-en-Y gastric bypass in patients over the age of 60 years

The prevalence of obesity is increasing even in older patients. Bariatric surgery is often considered more risky in this group, and not necessarily associated with the same benefits as in younger patients. In France, guidelines recommend to assess indication for surgery based on comorbidities and physiological age.

Rôle de la chirurgie laparoscopique dans le traitement de la maladie de reflux gastro-oesophagien [Laparoscopic treatment of gastroesophageal reflux disease]

Un certain nombre de malades ne sont toujours pas soulagés de manière satisfaisante par le traitement médical de la maladie de de reflux gastro-oesophagien (MR). Ce travail rapport notre expérience de 55 malades ayant bénéficié d'un montage anti-reflux réalisé par laparoscopie entre février 1992 et février 1997. La durée opératoire moyenne a été de 181 minutes, et tend à diminuer. La médiane de s&jour postopératoire a été de 4 jours. Quatre-vingt-neuf pour-cent des malades ont eu un suivi complet de 2 à 62 mois. Nonante-deux pour-cent d'entre eux étaient satisfaits ou très satisfaits du résultat. L'enthousiasme lié au traitement laparoscopique de la MR est justifié. Les résultats dépendent de la maîtrise technique du chirurgien, de sa connaissance de la MR, et de ses capacités à adapter le type de montage anti-reflux en fonction de l'évaluation préopératoire. L'intervention donne alors un résultat prévisible, ce qui incite à la proposer aux malades mal contrôlés médicalement, ou qui préfèrent éviter les contraintes d'un traitement de maintien à long terme.
