The Utilisation of Digital Applications for Measuring Patient Outcomes Following Bariatric Surgery: a Systematic Review and Meta-analysis of Comparative Studies.

In the context of escalating obesity rates, bariatric surgery holds a crucial role in managing severely obese patients. With a demonstrated effectiveness in weight loss and with the advent of ambulatory surgery, bariatric surgery allows for a streamlined care pathway, ideally suited for postoperative surveillance using digital health applications. The aim of this systematic review and meta-analysis is to evaluate the effect of eHealth-delivered health services or support for adults undergoing bariatric surgery. Five studies, encompassing 2210 patients, were analysed. The intervention group showed a 10% increase in total weight reduction and a 22% reduction in excess weight loss. ED visitation rates also trended towards reduction. Despite the absence of clear statistical superiority for DHA, the findings suggest potential benefits of DHA in postoperative monitoring.

Is a giant incisional hernia a contraindication for laparoscopic cholecystectomy?

Laparoscopic cholecystectomy (LC) is one of the most commonly performed surgical procedures worldwide. A previous abdominal operation is not considered a significant risk factor for conversion to open cholecystectomy. We describe the case of an 80-year-old woman with a surgical history of a giant uncomplicated incisional midline hernia presenting at our department with choledocholithiasis and acute cholangitis. After an ERCP with extraction of common bile duct stones, a LC was planned. The first trocar was inserted in the right midclavicular line, using an open technique and a careful inspection of the abdominal cavity and the hernia sac content. An uncomplicated cholecystectomy was performed and the postoperative course was uneventful.

A giant parastomal hernia in a high risk patient: preparation to make surgery worthwhile.

BACKGROUND: Parastomal hernia (PH) is a frequent and well-known complication of stoma placement. Most PHs are asymptomatic and those who are not are usually well tolerated by patients. Thus, watchful waiting is a common practice. Nevertheless, this management policy is associated with a risk of complications and with an inevitable risk of hernia enlargement, complicating its subsequent surgery. Moreover, PH can affect body image and alter the quality of life. METHODS: We herein present a complex case of a 67-year-old man with multiple comorbidities, who presented with an uncommon, below knee, giant PH, which was managed in a two-steps surgery by a multidisciplinary team comprising a senior digestive surgeon, experienced in abdominal wall repair, cardiologist, pulmonologist, anesthesiologist, psychiatrist, dietitian and physiotherapist. RESULT: Treatment started with 8 months hygienic measures comprising smoking cessation, strict control of diabetes and hypertension, a strict diet, and a physical fitness and pulmonary rehabilitation program. Two steps surgery started by colostomy transposition along with pre-peritoneal mesh repair to the right side and the second step consisted of a prophylactic PH repair using a Key-hole preperitoneal polypropelene mesh. CONCLUSION: PH is a common and sometimes inevitable complication of stoma creation. The success achieved by operating a heavily morbid patient, is only possible through the combined efforts of the multidisciplinary team and a preoperative rigorous management.

Esophageal cancer: Outcome and potential benefit of esophagectomy in elderly patients.

BACKGROUND: This analysis evaluated the morbimortality and the potential benefit of esophagectomy for cancer in elderly patients. METHODS: Patients who underwent esophagectomy for EC were divided into elderly (≥70 years) and nonelderly (<70 years) groups. The groups were compared regarding patient and tumor characteristics, postoperative morbimortality, and disease-free, overall and cancer-specific survival. RESULTS: Sixty-one patients were classified into elderly, and 187 into nonelderly groups. The elderly were characterized by a higher rate of WHO score (p < 0.0001), higher cardiac (p < 0.004) and renal (p < 0.023) comorbidities. The rate of neoadjuvant therapy and especially of neoadjuvant CRT was significantly lower in elderly patients (p < 0.018 and p < 0.007). Operative morbidity was also higher in this group (p < 0.024). The 30- and 90-day mortality was 8.2 and 11.5%, respectively in elderly patients and 0.5 and 3.2% in nonelderly patients (p < 0.004 and p < 0.012). This 90-day mortality decreased when specific surgery-related deaths were taken into consideration. OS and DFS were significantly better in the nonelderly group (p < 0.003 and p < 0.005) while no difference was observed for cancer-specific survival (CSS). CONCLUSION: No difference in CSS was observed. Although elderly patients with EC had higher postoperative morbimortality, the age should not be a criterion whether to perform, or not to perform, esophagectomy. This decision must be based on the balance between the patient's general condition and aggressive disease.

Salvage esophagectomy after failure of definitive radiochemotherapy for esophageal cancer.

BACKGROUND: Definitive radiochemotherapy (dRCT) in locally advanced esophageal cancer is associated with a high rate of loco-regional recurrence. In this condition, salvage esophagectomy may be considered as a therapeutic option. The aim of this analysis is to evaluate the feasibility and the morbi-mortality of this strategy. METHODS: Between January 2006 and April 2014, 208 patients underwent esophagectomy for esophageal cancer at ULB-Erasme-Bordet. Thirty-two patients received a preoperative radiochemotherapy (pRCT) followed by planned esophagectomy (Group 1) for locally advanced disease. Sixteen patients underwent salvage esophagectomy for recurrence or failure after dRCT (Group 2). Data on post-operative morbidity and mortality and survival were collected and analyzed. RESULTS: An increase of overall morbidity was detected in Group 2 as compared to Group 1 (43% vs. 37.5%), mainly related to respiratory complications (35.5% vs. 28%) and anastomotic leak (25% vs. 3%). No 90-days mortality was observed in the two surgical groups. The 1, 2, and 3-year survival rates after surgery were respectively 89%, 80%, and 71% for Group1 and 84%, 73%, and 63% for Group 2. CONCLUSIONS: In our experience, both salvage esophagectomy and esophagectomy after pRCT showed good survival results with low postoperative morbidity and mortality. Salvage surgery remains a therapeutic indication in selected patients. J. Surg. Oncol. 2016;114:833-837. © 2016 2016 Wiley Periodicals, Inc.

New Trends in Acute Management of Colonic Diverticular Bleeding: A Systematic Review.

Colonic diverticular disease is the most common cause of lower gastrointestinal bleeding. In the past, this condition was usually managed with urgent colectomy. Recently, the development of endoscopy and interventional radiology has led to a change in the management of colonic diverticular bleeding.The aim of this systematic review is to define the best treatment for colonic diverticular bleeding.A systematic bibliographic research was performed on the online databases for studies (randomized controlled trials [RCTs], observational trials, case series, and case reports) published between 2005 and 2014, concerning patients admitted with a diagnosis of diverticular bleeding according to the PRISMA methodology.The outcomes of interest were: diagnosis of diverticulosis as source of bleeding; incidence of self-limiting diverticular bleeding; management of non self-limiting bleeding (endoscopy, angiography, surgery); and recurrent diverticular bleeding.Fourteen studies were retrieved for analysis. No RCTs were found. Eleven non-randomized clinical controlled trials (NRCCTs) were included in this systematic review. In all studies, the definitive diagnosis of diverticular bleeding was always made by urgent colonoscopy. The colonic diverticular bleeding stopped spontaneously in over 80% of the patients, but a re-bleeding was not rare. Recently, interventional endoscopy and angiography became the first-line approach, thus relegating emergency colectomy to patients presenting with hemodynamic instability or as a second-line treatment after failure or complications of hemostasis with less invasive treatments.Colonoscopy is effective to diagnose diverticular bleeding. Nowadays, interventional endoscopy and angiographic treatment have gained a leading role and colectomy should only be entertained in case of failure of the former.

Clinical role of gasless laparoscopic adrenalectomy.

BACKGROUND: Several studies have demonstrated that the pneumoperitoneum (PNP) may have several hemodynamic, metabolic, neurologic, and humoral effects; in a limited number of patients, these effects represent a contraindication to the use of the PNP in the presence of glaucoma, cardiovascular insufficiency, advanced chronic obstructive bronchitis, and neurologic disease. PATIENTS AND METHODS: Between May 2002 and July 2008, we performed 9 laparoscopic gasless adrenalectomies in 8 patients (5 male and 3 female): 4 left, 3 right, and 1 bilateral, treated in 2 different operations. Mean age was 54.8 years (range: 34 to 76 y). Preoperative diagnosis was Cushing in 5 cases, pheochromocytoma in 1 case, incidentaloma in 1 case, and Conn in 2 cases. Postoperative histologic findings were cortical adenoma in 6 cases, pheochromocytoma in 1 case, and cortical hyperplasia in 2 cases. Contraindication to PNP were vascular endocranicanic malformation, acute glaucoma, history of vascular cerebral accident and hypertensive retinopathy, and recent neurosurgical intervention. We performed laparoscopic adrenalectomy in lateral flank position, using the LaparoTenser, an abdominal wall retractor, with 2 curved needles (Aghi Pluriplan) placed in the subcutaneous tissue of the anterolateral abdominal wall that allows low-pressure PNP offering a better view without negative effects of intra-abdominal pressure. RESULTS: The mean operative time was 73 minutes (range: 45 to 120 min): left average 71.2 minutes, right average 75.0 minutes. The mean postoperative hospital stay was 3.38 days (range: 3 to 5 d). There was no conversion to open surgery. There were no intraoperative or postoperative complications. All patients are alive and there were no recurrences. CONCLUSIONS: The gasless technique is a valid alternative to PNP when patients present a contraindication to the PNP, as it makes it possible to avoid the risks of intra-abdominal pressure and to conserve the advantages of a mini-invasive access.

Laparoscopic adjustable silicone gastric banding vs laparoscopic vertical banded gastroplasty in morbidly obese patients: long-term results of a prospective randomized controlled clinical trial.

BACKGROUND: Aim of the study is to present long-term results of a prospective randomized single-institution clinical trial comparing laparoscopic adjustable silicone gastric banding (LASGB) with laparoscopic vertical banded gastroplasty (LVBG) in morbid obesity. METHODS: A total of 100 morbidly obese patients (body mass index 40 to 50 kg/m2) were randomized to LASGB (n=49) or LVBG (n=51) and followed up for a minimum of 7 years. RESULTS: Mean operative time was 65.4 min in LASGBs and 94.2 min in LVBGs (p<0.05); mean hospital stay was 3.7 and 6.6 days, respectively (p<0.05). Late complication rates were 36.7% in LASGBs vs 15.7% in LVBGs at 3 years (p<0.05), 46.9% vs 43.1% at 5 years (NS), and 55.1% vs 47.1% at 7 years (NS). Late reoperation rates were 28.6% in LASGBs and 2.0% in LVBGs at 3 years (p<0.001), 38.8% and 2.0% at 5 years (p<0.001), and 46.9% and 7.8% at 7 years (p<0.001). Excess weight loss in LASGBs was 41.8% at 3 years, 33.2% at 5 years, and 29.9% at 7 years; excess weight loss in LVBGs was 60.9%, 57%, and 53.1%, respectively (p<0.05). CONCLUSIONS: This study demonstrates that in a carefully selected group of patients, LVBG is significantly more effective than LASGB in terms of late complications, late reoperations, and long-term results on weight loss.

Randomized controlled trial of laparoscopic Heller myotomy plus Dor fundoplication versus Nissen fundoplication for achalasia: long-term results.

OBJECTIVES: To compare in a prospective, randomized trial the long-term results of laparoscopic Heller myotomy plus Dor fundoplication versus laparoscopic Heller myotomy plus floppy-Nissen for achalasia. SUMMARY BACKGROUND DATA: Anterior fundoplication is usually performed after Heller myotomy to control GER; however, the incidence of postoperative GER ranges between 10% and 30%. Total fundoplication may aid in reducing GER rates. METHODS: From December 1993 to September 2002, 153 patients with achalasia underwent Heller laparoscopic myotomy plus antireflux fundoplication. Of these, 9 were excluded from the study. The remaining 144 patients were randomly assigned to 2 treatment groups: Heller laparoscopic myotomy plus anterior fundoplication (Dor procedure) or Heller laparoscopic myotomy plus total fundoplication (floppy-Nissen procedure). The primary end point was incidence of clinical and instrumental GER after a minimum of 60 months follow-up. The secondary end point was recurrence of dysphagia. Follow-up clinical assessments were performed at 1, 3, 12, and 60 months using a modified DeMeester Symptom Scoring System (MDSS). Esophageal manometry and 24-hour pH monitoring were performed at 3, 12, and 60 months postoperative. RESULTS: Of the 144 patients originally included in the study, 138 were available for long-term analysis: 71 (51%) underwent antireflux fundoplication plus a Dor procedure (H + D group) and 67 (49%) antireflux fundoplication plus a Nissen procedure (H + N group). No mortality was observed. The mean follow-up period was 125 months. No statistically significant differences in clinical (5.6% vs. 0%) or instrumental GER (2.8% vs. 0%) were found between the 2 groups; however, a statistically significant difference in dysphagia rates was noted (2.8% vs. 15%; P < 0.001). CONCLUSIONS: Although both techniques achieved long-term GER control, the recurrence rate of dysphagia was significantly higher among the patients who underwent Nissen fundoplication. This evidence supports the use of Dor fundoplication as the preferred method to re-establish GER control in patients undergoing laparoscopic Heller myotomy.

[Laparoscopic adrenalectomy: our experience]. / La surrenalectomia laparoscopica: nostra esperienza.

Since 2002 19 laparoscopic adrenalectomies with a lateral transperitoneal access have been performed at our Division of Surgery. Three patients had Conn's syndrome, 8 incidentaloma, 4 pheochromocytoma, 2 Cushing's syndrome, 1 metastases from a contralateral renal cancer and 1 metastases from lung cancer. The parameters considered for data analysis were: intra- and postoperative hypertensive crises, haemorrhage, subcutaneous emphysema, conversions, dura- tion of surgery, hospital stay, postoperative comfort, and canalisation and mobilisation times. The results obtained in our experience were comparable to those reported in the literature, confirming the reproducibility and feasibility of this type of surgical procedure. Comparison of the data obtained with laparoscopic, surgery and those obtained with traditional surgical treatment suggest that it is reasonable to claim that the laparoscopic approach is today the gold standard for adrenal surgery.

Acute nonspecific abdominal pain: A randomized, controlled trial comparing early laparoscopy versus clinical observation.

AIMS: To evaluate, in a prospective, randomized, single-institution trial, the role of early laparoscopy in the management of nonspecific abdominal pain (NSAP) in young women. PATIENTS AND METHODS: Women aging from 13 to 45 years, admitted for NSAP at the emergency department, were included in the study. Exclusion criteria were pregnancy, previous appendectomy, contraindications to laparoscopy, diagnosis of malignancy, or chronic disease. NSAP was defined as an abdominal pain in right iliac or hypogastric area lasting more than 6 hours and less than 8 days, without fever, leukocytosis, or obvious peritoneal signs and uncertain diagnosis after physical examination and baseline investigations including abdominal sonography. Patients were randomly assigned to early (<12 hours from admission) laparoscopy group (LAP) or to clinical observation group (OBS). After discharge a follow-up was carried out. RESULTS: From January 2001 to February 2004, 508 female patients without previous abdominal surgery were evaluated in admitting area for acute right iliac or hypogastric abdominal pain, in 373 patients diagnosis was established for obvious signs or with baseline investigations. Of the remaining 135 patients, 31 were excluded from study for various reasons, 53 patients were randomly assigned to LAP and 51 to OBS. Groups were similar for age, mean BMI, white blood cell count, and duration of pain. During hospitalization diagnosis was established in 83.4% of the LAP and in 45.1% of OBS (P < 0.05). Twenty patients of OBS (39.2%) were operated during observation because of worsening of symptoms or appearance of peritoneal sign. Diagnoses in LAP were appendicitis in 16 patients (30.1%), pelvic inflammatory disease in 7 (13.2%), carcinoid in 1 (1.9%), other in 18 (33.9%), no diagnosis in 11 (20.7%); diagnoses in OBS were appendicitis in 3 patients (5.8%), pelvic inflammatory disease in 8 (15.6%), other in 12 (23.5%), and no diagnosis in 28 (54.9%). Mean length of hospital stay was 3.7 +/- 0.8 days in LAP and 4.7 +/- 2.4 days in OBS (P < 0.05); no differences were found regarding mortality, morbidity, radiation dose, and analgesia. Mean follow-up time was 29.3 months (range, 12-60 months) for LAP and 30.6 months for OBS (range, 12-60 months). After 3 months from discharge, 20% of patients in LAP and 52% in OBS had recurrent abdominal pain (P < 0.05); after 12 months, 16% in LAP and 25% in OBS (P = not significant). Six patients in OBS required readmission for surgery. CONCLUSIONS: Compared with active clinical observation, early laparoscopy did not show a clear benefit in women with NSAP. A higher number of diagnosis and a shorter hospital stay in the LAP group did not led to a significant reduction in symptoms recurrences at 1 year.
