RESUMEN

BACKGROUND: Adverse economic conditions often prevent the widespread implementation of modern surgical techniques in third world countries such as in Sub-Sahara Africa. AIM OF THE STUDY: To demonstrate that a modern technique (laparoscopic totally extraperitoneal inguinal hernioplasty [TEP]) can safely be performed at significantly lower cost using inexpensive mesh material. SETTINGS: Douala University Hospital Gynecology, Obstetrics and Pediatrics and two affiliated centers, Ayos Regional Hospital and Edéa Regional Hospital in Cameroon. PATIENTS AND METHODS: Prospective randomized controlled trial (RCT) of consecutive adult patients presenting with primary inguinal hernia treated by TEP, comparing implantation of sterilized mosquito mesh (MM) with conventional polypropylene mesh (CM). Primary endpoints were peroperative, early and midterm postoperative complications and hernia recurrence at 30 months. RESULTS: Sixty-two patients (48 males) were randomized to MM (n = 32) or CM (n = 30). Groups were similar in age distribution and occupational features. Peroperative and early outcomes differed in terms of conversion rate (2/32 MM) due to external (electrical power supply) factors and mesh removal for early obstruction (1/30 CM). No outcome differences, including no recurrences, were noted after a median follow-up of 21 months. CONCLUSION: In this RCT with medium-term follow-up, TEP performed with MM appears not inferior to CM.

RESUMEN

AIM: To access the incidence and predictive factors of incisional hernia after single-incision laparoscopic cholecystectomy (SILC). METHODS: Eighty-two consecutive patients operated on for uncomplicated cholelithiasis between 2009 and 2013 were eligible for the study. Clinical outcome was assessed by a combination of case notes review, office consultation and telephone interview. Long-term incisional hernia rate was the major outcome of the study. Secondary outcome was the evaluation of predictive factors. Univariate and multivariate statistical analyses were performed using the following variables: age, gender, ASA score, BMI, risk, or comorbidity factors and surgical site infection. RESULTS: Six patients (7 %) were lost to follow-up after the 1-month office visit and excluded. The study group consisted of 16 men and 60 women with a median age of 42 years (range 18-69) and a BMI of 25 (range 19-34). Eight patients had risk or comorbidity factors, 46 were classified ASA I, and 30 ASA II. Early postoperative course was uneventful in all cases but two patients developed a superficial wound abscess after hospital discharge. With a median follow-up of 44 months (range 12-72), incisional hernia was noted in six patients (7.9 %). Multivariate logistic analysis revealed that age (OR 1.08, 95 % CI 1.00-1.16, p < 0.038) and BMI (OR 1.37, 95 % CI 1.03-1.82, p < 0.029) were independent predictive factors of developing an incisional hernia. The incidence of hernia was, respectively, 15 % in patients with an age ≥ 50 and 33 % in patients with a BMI ≥ 30. CONCLUSION: After SILC, we noted an incisional hernia rate of 8 %. To decrease the risk of developing that specific complication, SILC should only be proposed to young and non-obese patients.

RESUMEN

OBJECTIVES: Sleeve gastrectomy (SG) has been used as the first step of a staged malabsorptive procedure for high-risk patients. More recently SG was proposed as an stand alone procedure in the treatment of morbidly obese patients. The aim of this study is to analyze perioperative outcome of morbid obese patients after SG. METHODS: 301 patients, 201 women and 100 men, undergoing SG were retrospectively analyzed. SG was performed by 17 surgeons all member of the Club Coelio. The mean BMI was 44.7kg/m2 (27.4-70.3 kg/m2). 34 patients (11.3%) of our series had SG as revisional surgery. These revisional procedures consisted of 32 conversions from gastric banding, 1 conversion from vertical gastroplasty (VBG) and 1 from transoral endoscopic gastroplasty. Among the 32 patients that had revisional SG after a gastric banding, 13 bands were removed at least 3 months before the revisional SG and 19 bands were removed during the SG procedure. Endpoints were perioperative morbidity and mortality and potential risk factors for complications, mainly per or postoperative bleeding or leakage. RESULTS: Overall mortality was 0% and morbidity was 10.3%. Perioperative bleeding occurred in 10 patients (3.3%), leakage in 12 patients (4%) patients and stenosis in 3 patients (1%). The risk of leakage was significantly higher after revisional bariatric surgery and in case of gastric perforation during surgery (p = 0.0001). Previous gastric banding is also associated with a higher risk of postoperative bleeding (p = 0.0006). CONCLUSIONS: SG can be safely performed but patients and surgeons must be aware of a higher risk of postoperative complications when SG is proposed as a revisional surgery.

RESUMEN

BACKGROUND: The aim of that study is to assess the surgical outcomes after laparoscopic repair of primary ventral hernias (PVH). METHODS: The series consisted of 118 consecutive patients presenting with PVH (13 epigastric and 105 umbilical hernias) operated between 2001 and 2010 by laparoscopy. Surgical repair consisted in intraperitoneal placement of a Parietex composite mesh centred on the defect with a minimum overlapping of 3 cm. The mesh was secured to the abdominal wall with a double crown of helical tacks alone or by an association of transfascial sutures and tacks. Patients' data were recorded prospectively. All patients were checked during office visit one month and one year after surgery and thereafter periodically evaluated by phone call. RESULTS: There were 32 women and 86 men with a mean age of 53 +/- 12 years and a body mass index (BMI) of 32 +/- 5. The median width of the defect was 2 cm (range : 1-6 cm). There was no conversion to open surgery. The mean operative time was 44 +/- 18 min. and the hospital stay 2 +/- 1 days. We noted 7 (6%) postoperative complications: 6 seromas and 1 hypodermitis. One month after surgery, no umbilical skin necrosis was observed and 102 patients (84%) considered the cosmetic result as excellent. With a mean follow-up of 66 +/- 37 months, no complication related to the use of the mesh was recorded and the recurrence rate was 3% (4/118). Predictive factors of recurrence were: BMI > or = 35 (14% (4/29), p < 0.001), mesh overlapping < 5 cm (20% (3/15), p < 0.002) and mesh fixation by tacks alone (8% (4/48), p < 0.05). CONCLUSION: Laparoscopic PVH repair is associated with very low morbidity, excellent cosmetic result and a recurrence rate of 3%. Improvement in surgical repair technique with systematic use of transfascial sutures and mesh overlapping > or = 5 cm should decrease the recurrence rate especially in obese patients.

RESUMEN

AIM: To compare surgical outcomes of patients presenting with uncomplicated cholelithiasis and operated by single incision (SILC) or by conventional laparoscopic cholecystectomy (CLC). METHODS: The series concerned 58 consecutive patients operated between October 2008 and October 2009. There were 11 men and 47 women with a mean age of 47 years and a BMI of 29. Six patients had a past surgical history with a midline incision. The main parameters analysed were duration of operation, morbidity, postoperative pain, return to normal activities and aesthetic result. One month and one year after surgery, the cosmetic result was assessed on a visual analogue scale (VAS), a score between 9 and 10 was considered as an excellent cosmetic result. RESULTS: A SILC was performed in 26 and a CLC in 32 patients. Patients in the SILC group were characterised by a lower BMI : 25 versus 32 (p <0.001) and by the absence of previous midline incision: 0/26 (0%) versus 6/32 (19%) (p <0.028). Outcomes were similar between groups except the aesthetic result. Multivariate statistical analysis revealed that the percentage of excellent cosmetic result was higher in SILC than in CLC group : respectively 73% (19/26) vs. 28% (9/32) one month postoperatively (OR : 5.3, 95% CI: 1-23, p <0.03) and 92% (22/24) versus 55% (17/31) one year postoperatively (OR : 6.9, 95% CI : 1-46, p < 0.04). CONCLUSIONS: Our study demonstrates that SILC is a feasible and safe procedure in a selected population. Compared to CLC, the only obvious benefit is a better cosmetic result that is still observed one year after surgery.

RESUMEN

The breast carcinoma metastases preferentially in the axillary lymph nodes, bones, lungs, liver and soft tissues. Gastrointestinal or bladder dissemination is very rare. We report the case of a 63-year-old female with a clinical presentation of acute cholecystitis, who underwent laparoscopic cholecystectomy in emergency. The gallbladder showed a nodule at the infundibulum, which was responsible for the gallbladder hydrops with macroscopic features of a cholangiocarcinoma. Histological examination disclosed a metastasis from a lobular breast carcinoma with positive hormone receptors, but no overexpression of the Neu oncogene. Immunohistochemistry showed positive staining for cytokeratin7 suggesting a lesion of breast origin. The absence of E-cadherin was consistent with lobular carcinoma while negative CA 19.9 excluded cholangiocarcinoma. The patient had received 15 years previously a right mastectomy with axillary dissection followed by chemotherapy and radiotherapy for breast carcinoma of ductal type labeled SBR stage III, pT3N1 M0, showing hormone receptors but absent Neu oncogene. Proofreading of the mastectomy histological slide concluded that it was a lobular rather than a ductal type carcinoma, confirming the finding of a gallbladder metastasis 15 years after the mastectomy. The patient showed no local recurrence or contralateral lesions on magnetic resonance imaging (MRI). The bone scan showed metastases in the skull, scapula, right rib cage, thoracolumbar spine and pelvis, also confirmed by MRI. A treatment with exemestane and zoledronic acid was introduced. The follow-up at 6 months showed regression of the bone lesions and absence of parenchymal new locations.

RESUMEN

The authors report a case of a 3 cm hepatocellular carcinoma at the junction of segments VI and VII with double bile duct tumoral thrombi (Types I and III). The type I thrombus was suspected during the pre-operative workup, but the type III bile duct tumoral thrombus (BDTT) was an intra-operative additional finding on cholangiography. The patient underwent a bisegmental posterolateral resection to remove the primary tumour and the first tumoral thrombus located in the posterolateral intrahepatic duct. A choledocotomy was also performed to remove, by balloon catheter, the floating thrombus located in the common bile duct just over the papilla. The authors discuss their diagnostic and therapeutic approach and review the literature.

RESUMEN

AIM: To compare the results of open and laparoscopic appendectomy and to determine if the laparoscopic approach might be more effective for some subgroups of patients. MATERIAL AND METHODS: We retrospectively analysed the computerised data of 326 consecutive adult patients operated on for suspected appendicitis between 2001 and 2005. The series consisted of 166 men and 160 women with a mean age of 32 +/- 16 years and a mean Body Mass Index (BMI) of 24 +/- 4. There were 265 ASA I, 46 ASA II and 5 ASA III patients. According to the surgeon's preference, 176 patients had an open appendectomy (OA) and 150 a laparoscopic appendectomy (LA). RESULTS: The mean operative time and hospital stay were equivalent in the two groups : respectively 49 +/- 19 min. and 4.1 +/- 2.5 days in OA and 50 +/- 16 min. and 3.5 +/- 1.8 days in LA. However, subgroup analysis revealed that overweight (BMI > 25) patients (n = 102) and patients with ectopic appendices (n = 86) had an obvious benefit from LA. In cases of OA, operative time and hospital stay were longer in overweight patients than in normal weight patients: respectively 63 +/- 20 min. and 5.3 +/- 2.9 days versus 44 +/- 16 min. (p < 0.01) and 3.7 +/- 2.2 days (p < 0.01). On the contrary, no difference was observed in the LA group. Operative time and hospital stay were also longer in patients with ectopic appendices submitted to OA than in patients with an appendix in the normal position: respectively 60 +/- 18 min. and 4.7 +/- 2.7 days versus 45 +/- 18 min. (p < 0.01) and 3.9 +/- 2.4 days (p < 0.01). Again, such a difference was not observed in cases of LA. We noted no mortality, but 24 patients (7%) developed an abdominal complication : 18 wound infections and 6 intra-abdominal abscesses. Wound infections were more common in the OA than in the LA group : 7.3% (13/176) versus 3.3% (5/150) (p = 0.1). In the LA group, 4 wound infections were observed in our early experience, at a time where no endoscopic bag was used for the removal of the appendix. The rate of intra-abdominal abscesses was similar: 1.7% (3/176) in the OA group and 2% (3/150) in the LA group. CONCLUSIONS: LA is an effective procedure with a reduced risk of developing wound infection. The laparoscopic approach is particularly effective for overweight patients and/or patients with ectopic appendices as far as shortening the operative time and hospital stay is concerned.
