Because of uncertainties about the complexity of laparoscopic ventral hernia repair for varying patient populations, surgeons may be reluctant to perform this procedure. This study aimed to delineate the risk factors that can be identified in the preoperative setting predictive of longer operative times and complexity in laparoscopic ventral hernia repair. ⋯ At least 10 preoperatively identifiable patient variables, either alone or in combination, are predictive of prolonged operative times during laparoscopic ventral hernia repair and may be used as surrogates to determine the complexity of a minimally invasive approach.

Obesity is becoming an epidemic health problem and is associated with concomitant diseases, such as sleep apnea syndrome and gastroesophageal reflux disease (GERD). There is no standardized diagnostic workup for the upper gastrointestinal tract in obese patients; many patients have no upper gastrointestinal symptoms, and few data are available on safety of endoscopy in morbidly obese patients. ⋯ Upper gastrointestinal endoscopy can be performed safely. However, careful monitoring and anesthesiological support are required for patients with concomitant diseases and those receiving sedation. Because 80% of the patients with pathological findings were asymptomatic, every morbidly obese patient should undergo endoscopy before bariatric surgery because there may be findings that might change the surgical strategy.

Fast-track (FT) recovery protocols have demonstrated advantages over historical recovery routines after open colectomy; however, their impact in recovery after laparoscopic colectomy is not clearly defined. This study was designed to determine whether patients who recover on FT protocol after laparoscopic colectomy have a shorter length of stay (LOS) and fewer complications compared with patients who recover on standard (non-FT) protocol. ⋯ Fast-track recovery is independently associated with a shorter LOS and decreased morbidity after laparoscopic right hemicolectomy.

The effect of mechanical ventilation tidal volume during pneumoperitoneum on shoulder pain after a laparoscopic appendectomy.
Postlaparoscopic shoulder pain (PLSP) frequently occurs after various laparoscopic surgical procedures. Its mechanism is commonly assumed to be overstretching of the diaphragmatic muscle fibers due to the pressure of a pneumoperitoneum, which causes phrenic nerve-mediated referred pain to the shoulder. Based on this hypothesis, we speculated that during inspiration, the lung could squeeze out the phrenic nerve with carbon dioxide gas against the constantly pressurized abdominal cavity with increasing tidal volume (V(T)). Thus, we examined whether mechanical ventilation with a low V(T) (LTV, V(T) 7 ml/kg) during a pneumoperitoneum might reduce PLSP in patients undergoing laparoscopic appendectomy compared with ventilation with the traditional V(T) (TTV, V(T) 10 ml/kg). ⋯ Mechanical ventilation with a reduced 7 ml/kg V(T) during a pneumoperitoneum does not reduce the frequency and severity of PLSP after laparoscopic appendectomy compared with ventilation with the traditional V(T) (10 ml/kg).

Laparoscopic splenectomy (LS) has become a safe and feasible procedure for cases involving spleens of normal size. Only a few publications report on the outcome of LS with preoperative splenic artery embolization (SAE) for massive splenomegaly. The authors present their experience in patients with massive splenomegaly who underwent laparoscopic-assisted splenectomy (LAS) or hand-assisted laparoscopic splenectomy (HALS) following SAE. ⋯ In the setting of massive splenomegaly, LAS or HALS with preoperative SAE is safe and has a low conversion rate. Postoperative imaging surveillance for PVT should be performed routinely in this patient population.
