Total mesorectal excision: a comparison of oncological and functional outcomes between robotic and laparoscopic surgery for rectal cancer.

BACKGROUND: Long-term data from the CLASICC study demonstrated the oncologic equivalence of laparoscopic and open rectal cancer surgery despite an increased circumferential resection margin involvement in the laparoscopic group in the initial report. Moreover, laparoscopic total mesorectal excision (TME) may be associated with increased rates of male sexual dysfunction compared to conventional open TME. Robotic surgery could potentially obtain better results than laparoscopy. The aim of this study was to compare the clinical and functional outcomes of robotic and laparoscopic surgery in a single-center experience. METHODS: This study was based on 100 patients who underwent minimally invasive anterior rectal resection with TME. Fifty consecutive robotic rectal anterior resections with TME (R-TME) were compared to the first 50 consecutive laparoscopic rectal resections with TME (L-TME). RESULTS: Median operative time was 270 min in R-TME and 275 min in L-TME. No conversions occurred in the R-TME group whereas six conversions occurred in the L-TME group. The mean number of harvested lymph nodes was 16.5 ± 7.1 for R-TME and 13.8 ± 6.7 for L-TME. The circumferential margin (CRM) was <2 mm in six L-TME patients, whereas no one in R-TME group had a CRM <2 mm. The International Prostate Symptom Score (IPSS) scores were significantly increased 1 month after surgery in both the L-TME and R-TME groups, but they normalized 1 year after surgery. Erectile function worsened significantly 1 month after surgery in both the groups but it was restored completely 1 year after surgery in the R-TME group and partially in the L-TME group. CONCLUSIONS: Robotic TME is oncologically safe and adequate for rectal cancer treatment, showing better results than laparoscopic TME in terms of CRM, conversions, and hospital length of stay. Better recovery in voiding and sexual function is achieved with the robotic technique.

Fully robotic treatment of an epiphrenic diverticulum: report of a case.

Epiphrenic diverticula are rare protrusions of the distal esophagus attributed to esophageal motility disorders or obstructive diseases. In presence of a relevant symptomatology, surgery is mandatory. Although many reports confirm the feasibility of the laparoscopic transhiatal approach, the mobilization of the esophagus and the myotomy appear challenging. The intrinsic characteristics of the da Vinci Robotic System could facilitate the approach to the esophagogastric junction and an extended mobilization of the esophagus. We describe a robotic transhiatal surgical treatment of an epiphrenic diverticulum with a Dor antireflux procedure. Robotic-assisted diverticulectomy appears feasible and safe with a low risk of esophageal perforation and pleura damage.

Laparoscopic treatment of a carcinoma of the cecum incarcerated in a right groin hernia: report of a case.

A carcinoma in a groin hernia is uncommon. We herein report a case of an intrasaccular carcinoma of the cecum in a right inguinoscrotal hernia with a simultaneous left inguinal hernia treated by a laparoscopic approach. A 70-year-old man presented with a painful, not completely reducible bilateral hernia. Blood examinations showed severe anemia. A computed tomography scan of the abdomen confirmed the presence of the cecum in the hernia sac, showing a round wall thickening of the herniated portion of the colon. A standard laparoscopic right colectomy with radical oncological purpose was performed. An incarcerated inguinal hernia is a relatively common surgical problem. In the case of anemia or other signs suggestive of malignancy, a specific preoperative work-up should be assessed. This case demonstrates that it is possible to perform an oncologically correct laparoscopic resection when the presence of malignancy is confirmed while performing an open traditional hernioplasty to avoid any possible contamination of the mesh.

The recurrent goiter: prevention and management.

AIM OF THE STUDY: Conservative surgery of thyroid is followed by recurrence in 2 to 70% of cases in an 8-20 years period. The surgical treatment of such recurrence is affected by higher morbidity than a primary total thyroidectomy. We wanted verify in our series this difference and discuss motivations for conservative or radical surgery of goiter. MATERIALS AND METHODS: We compared a series of 91 primary total thyroidectomy (A) with 11 cases of total thyroidectomy for recurrence (B) performed between 2001 and 2005. RESULTS: Postoperative complications were: Transient hypocalcemia 7 (7.69%) in A and 3 (27%) in B, Permanent hypocalcemia only 1 (9%) in B, Transient RLN deficit 2 (2.1%) in A and 2 (18.1%) in B. CONCLUSIONS: Due to the need of a lifelong therapy with LT4 no utility is observed in conservative surgery of thyroid. Further, in primary surgery, differences in incidence of perioperative complications cannot be advocated to justify a conservative approach. Sophisticated technologies are not able to prevent all damages to parathyroid or to recurrent nerves when operating on recurrent goiter. Our experience confirms the results of a review of literature on this topic: the best management of recurrent goiter is its prevention by primary total thyroidectomy.

Very atypical presentation of a retroperitoneal "atypical lipoma". A well differentiated liposarcoma presenting as sciatic hernia.

Unlike hernias and neoplasms of any other body site, the sciatic hernia is uncommon and the finding of an atypical lipoma in it is probably unique. In such instance making the correct diagnosis is paramount in order to perform a procedure with a radical intent. A CT scan must be considered any time a rare form of hernia is observed and the surgical treatment of a retroperitoneal lipoma has to be radical, to prevent a recurrence. This is the strategy followed by the authors in a case of a 53 year old lady presenting with a large retroperitoneal lipomatous neoplasm within a sciatic hernia.

Robotic adrenalectomy: technical aspects, early results and learning curve.

BACKGROUND: Adrenal surgery is undergoing continuous evolution, and robotic technology may extend indications for a minimally invasive approach to adrenalectomy. METHODS: Thirty robot-assisted unilateral transperitoneal adrenalectomy procedures have been performed at our Department over the last 5 years. The presence of bilateral lesions and vascular involvement were the only contra-indications for a minimally invasive approach. Several patients presented with significant co-morbidities: BMI > 35 kg/m(2) (20%); ASA score III-IV (58.7%); and moderate to severe impaired respiratory function (36.6%). In addition, 40% of patients had undergone previous abdominal surgery. RESULTS: Two patients presented with intra-operative complications (6.6%) and only one patient required conversion to an open procedure (3.3%). None of the patients required intraoperative transfusions. Hospital morbidity was 10% but no mortality was recorded. The mean hospital stay was 5.2 ± 2.2 days. The mean size of the resected adrenal mass was 5.1 ± 2.4 cm. A significant reduction in operative times was found with gaining experience. CONCLUSIONS: Thanks to robotic technology, some subpopulations of patients with clinical or oncological contra-indications to laparoscopic treatment may be addressed with minimally invasive treatment.

Robotic splenectomy for mesothelial cyst: a case report.

Cystic lesions of the spleen represent a rare entity with an overall incidence of 0.5% among splenectomies. They can remain asymptomatic in 30% to 60% of patients or may cause symptoms for secondary compression of adjacent structures. Peripheral cysts may be suitable for conservative treatment whereas splenectomy is the accepted procedure for bulky and/or central lesions. Laparoscopy is the standard approach for elective splenic surgery, but in the last decade, introduction of the da Vinci robotic system has represented a further improvement in minimally invasive surgery, thanks to 3-dimensional vision and more accurate motion control. Herein, we report a case of a mesothelial splenic cysts successfully treated by robotic splenectomy; some anatomical considerations and technical aspects of robotic procedures have been discussed: it is a feasible and safe approach, particularly indicated in the presence of anatomic features such as an enlarged pancreatic tail and a type II vascular pattern of splenic pedicle. In such patients, the choice of a robotic approach may decrease the risk of intraoperative bleeding, thereby representing a further improvement in laparoscopic techniques.

Splenic rupture after colonoscopy: Report of a case and review of literature.

Splenic rupture is a rare complication of colonoscopy. For this reason the diagnosis could be delayed and the outcome dismal. Fifty-four cases of splenic rupture after colonoscopy have been described in the literature. The majority of the cases required emergent or delayed splenectomy, 13 of these cases were treated conservatively. The main feature that stands out from the review of the literature is the "surprise" of this unexpected complication. This factor explains the elevated mortality (2 out of 54 cases), likely due to the delay in diagnosis. The case here described is probably among the most complex published in the literature; in fact the presence of dense intra-abdominal adhesions not only contributed to the complication itself, but also explain the confinement of the hemoperitoneum to the left supra-mesocolic space and the delayed presentation (13 days from the time of the trauma).
